PROSPECTUS SUMMARY THIS SUMMARY HIGHLIGHTS INFORMATION CONTAINED ELSEWHERE IN THIS PROSPECTUS. YOU SHOULD READ THE ENTIRE PROSPECTUS CAREFULLY, INCLUDING THE "RISK FACTORS" SECTION. OUR COMPANY We are a global developer, manufacturer and marketer of innovative, enabling tools used in drug discovery research at pharmaceutical and biotechnology companies, universities and government laboratories. We sell approximately 10,000 products to more than 5,000 customers in over 60 countries. Our proprietary products accounted for approximately 82% of our revenues for the nine months ended September 30, 2000. We have designed our tools to accelerate the speed and to reduce the cost at which our customers can discover and commercialize new drugs. By providing research tools, we participate in the revolutions in genomics, the study of genes, and proteomics, the study of proteins, without bearing the risks inherent in attempting to discover new drugs. Since our reorganization in March 1996, we have focused on developing tools to alleviate two critical bottlenecks in the drug discovery process: - PROTEIN PURIFICATION, which is the removal of contaminants such as salts, buffers, detergents and cellular debris from a protein sample, and - ADMET SCREENING, which is the testing of the absorption, distribution, metabolism, elimination and toxicology properties of drug candidates. Our proteomics products are tools that allow researchers to purify and analyze proteins contained in a sample. Our ADMET screening products are tools that enable researchers to test drug candidates to determine their absorption, distribution, metabolism, elimination and toxicology properties prior to conducting costly clinical trials. We market our products primarily through our 1,000 page catalog to approximately 100,000 researchers worldwide. Our catalog is also available on our website. We distribute most of our products directly through our operations in the United States, the United Kingdom, Germany, France and Canada. In addition to our catalog distribution channel, we have a long-standing distribution and marketing relationship with Amersham Pharmacia Biotech, or APBiotech, one of the largest companies in the life sciences industry. OUR OPPORTUNITY Drug discovery is a time-consuming and costly process. In the pre-genomics era, the compound development, primary screening and clinical trials stages were bottlenecks in this process. The recent successes of genomics, combinatorial chemistry (the automated production of large numbers of chemical compounds) and high throughput screening have alleviated the bottlenecks at the compound development and primary screening stages. However, these bottlenecks have been replaced by bottlenecks at later stages in the drug discovery process. Our opportunity lies in alleviating these bottlenecks with products that increase the productivity and reduce the cost of drug discovery. OUR PRODUCTS We have a broad array of established products for proteomics and ADMET screening. We believe our products offer drug discovery researchers the most comprehensive protein purification and 1

ADMET screening solutions. In the past two years, we have expanded our product base by introducing the following proprietary tools: PROTEIN PURIFICATION: - specially coated pipette tips, which are small plastic tubes coated on the inside with a material that selectively extracts proteins but not contaminants, - micro spin columns, which are small plastic tubes partially filled with a material that selectively extracts proteins but not contaminants, and - micro dialyzers, which are small plastic tubes each containing a dialysis membrane which allows small molecules to pass through but retains large molecules such as proteins. ADMET SCREENING: - NaviCyte diffusion chambers, which measure drug absorption by simulating membranes in the human body, - small plastic plates with 96 wells, which each contain a dialysis membrane that allows small molecules to pass through but retains large molecules such as proteins, and - ScanTox instruments, which enable toxicology testing without the use of animals. In protein purification, these new products increase productivity and reduce cost by avoiding the cumbersome sample handling steps required by current technology and by being compatible with automated liquid-handling robots. Many of the products are available in 96 well plate formats. In ADMET screening, these new products lower cost and increase automation by using molecular, cellular, tissue and organ based assays to reduce the use of live animals. In addition to our proprietary products, we provide a broad selection of non-proprietary products that are frequently used in conjunction with our proprietary products. We seek to be a single source for our customers' product needs in protein purification and ADMET screening. OUR STRATEGY Our goal is to become the leading provider of innovative, enabling technologies and products for proteomics and ADMET research in the drug discovery process. Key elements of our strategy are to: - establish our new proteomics and ADMET screening products as industry standards, - launch a broad range of innovative new tools for drug discovery, - leverage our existing distribution and marketing channels, - provide a single source of tools for our customers' research needs in proteomics and ADMET screening, and - acquire complementary technologies. ------------------------ We organized our company as a Massachusetts corporation on March 7, 1996 in connection with our purchase of a portion of the assets of Harvard Apparatus, a business which, with its predecessors, had been in existence since 1901.

RISK FACTORS AN INVESTMENT IN OUR COMMON STOCK INVOLVES SIGNIFICANT RISKS. YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS BEFORE YOU DECIDE TO BUY OUR COMMON STOCK. IF WE ARE UNABLE TO ACHIEVE AND SUSTAIN MARKET ACCEPTANCE OF OUR NEW PROTEOMICS AND ADMET SCREENING PRODUCTS ACROSS THEIR BROAD INTENDED RANGE OF APPLICATIONS, WE WILL NOT GENERATE EXPECTED REVENUE GROWTH. Our business strategy depends on our successfully developing and commercializing our new proteomics and ADMET screening technologies to meet our customers' expanding needs and demands. For example, our recent acquisition of AmiKa Corporation involved the purchase of the technology that we are using to develop our 96 well plate for serum protein binding analysis. Market acceptance of this and other new products will depend on many factors, including the extent of our marketing efforts and our ability to demonstrate to existing and potential customers that our technologies are superior to other technologies and products that are available now or may become available in the future. If our new products do not gain market acceptance, it could materially adversely affect our business and future growth prospects. OUR PRODUCTS COMPETE IN MARKETS THAT ARE SUBJECT TO RAPID TECHNOLOGICAL CHANGE, AND THEREFORE ONE OR MORE OF OUR PRODUCTS COULD BE MADE OBSOLETE BY NEW TECHNOLOGIES. Because the market for drug discovery tools is characterized by rapid technological change and frequent new product introductions, our product lines may be made obsolete unless we are able to continually improve our existing products and develop new products. To meet the evolving needs of our customers, we must continually enhance our current and planned products and develop and introduce new products. However, we may experience difficulties which may delay or prevent the successful development, introduction and marketing of new products or product enhancements. In addition, our product lines are based on complex technologies which are subject to rapid change as new technologies are developed and introduced in the marketplace. We may have difficulty in keeping abreast of the rapid changes affecting each of the different markets we serve or intend to serve. Our failure to develop and introduce products in a timely manner in response to changing technology, market demands or the requirements of our customers could cause our product sales to decline, and we could experience significant losses. We offer and plan to offer a broad product line and have incurred and expect to continue to incur substantial expenses for development of new products and enhanced versions of our existing products. The speed of technological change in our market may prevent us from being able to successfully market some or all of our products for the length of time required to recover their often significant development costs. Failure to recover the development costs of one or more products or product lines could decrease our profitability or cause us to experience significant losses. WE HAVE LIMITED EXPERIENCE IN MANUFACTURING SOME OF OUR PRODUCTS WHICH COULD CAUSE PROBLEMS OR DELAYS RESULTING IN LOST REVENUE. We have only recently begun to manufacture and therefore currently have limited manufacturing capacity for some of our products, such as our PrepTip protein purification pipette tips. If we fail to manufacture and deliver products in a timely manner, our relationships with our customers could be seriously harmed, and our revenue could decline. To achieve the production levels necessary for successful commercialization, we will need to scale-up our manufacturing facilities and establish automated manufacturing methods and quality control procedures. We cannot assure you that manufacturing or quality control problems will not arise as we attempt to scale-up our production or that we can scale-up manufacturing and quality control in a timely manner or at commercially 6

reasonable costs. If we are unable to manufacture these products consistently on a timely basis because of these or other factors, we may not achieve the level of sales from these products that we otherwise anticipate. IF AMERSHAM PHARMACIA BIOTECH TERMINATES ITS DISTRIBUTION AGREEMENT WITH US OR FAILS TO PERFORM ITS OBLIGATIONS UNDER OUR DISTRIBUTION AGREEMENT, IT COULD IMPAIR THE MARKETING AND DISTRIBUTION EFFORTS FOR SOME OF OUR PRODUCTS AND RESULT IN LOST REVENUES. For the nine months ended September 30, 2000, approximately 39% of our revenues were generated through an agreement with Amersham Pharmacia Biotech, or APBiotech, under which APBiotech acts as our primary marketing and distribution channel for the products of our Biochrom subsidiary. Under the terms of this agreement, we are restricted from allowing another person or entity to distribute, market and sell the majority of the products of our Biochrom subsidiary. We are also restricted from making or promoting sales of the majority of the products of our Biochrom subsidiary to any person or entity other than APBiotech or its authorized subdistributors. We have little or no control over APBiotech's marketing and sales activities or the use of its resources. APBiotech may fail to purchase sufficient quantities of products from us or perform appropriate marketing and sales activities. The failure by APBiotech to perform these activities could materially adversely affect our business and growth prospects during the term of this agreement. In addition, our inability to maintain our arrangement with APBiotech for product distribution, could materially impede the growth of our business and our ability to generate sufficient revenue. Our agreement with APBiotech may be terminated under some circumstances, including in the event of a breach of a material term by us. This agreement has a perpetual term; however, it may be terminated by either party upon 18 months' prior written notice. While we believe our relationship with APBiotech is good, we cannot guarantee that the contract will be renewed or that APBiotech will aggressively market our products in the future. WE MAY BE ADVERSELY AFFECTED BY THREATENED LITIGATION INVOLVING HARVARD UNIVERSITY. We received correspondence from counsel to Harvard University on November 7, 2000 alleging trademark infringement, false designation of origin, unfair competition and cybersquatting and threatening legal action against us if we do not take certain steps, including ceasing our use of the term "Harvard Bioscience" and other terms containing the term "Harvard." We do not currently intend to take such steps, and we believe it is likely that Harvard University will pursue this matter against us. This legal action could include, among other things, the filing of a complaint against us seeking injunctive relief and treble damages with respect to these claims. We may suffer adverse consequences as a result of this matter which we cannot now predict. If claims for injunctive relief or other damages are asserted and are decided against us, we could suffer monetary damages, lose our ability to use the names "Harvard Bioscience" and "Harvard Apparatus," lose the reputation and goodwill associated with these names and ultimately experience decreased revenues and earnings in subsequent periods. In addition, any lawsuit or claim for injunctive relief may result in significant litigation expenses. OUR COMPETITORS AND POTENTIAL COMPETITORS MAY DEVELOP PRODUCTS AND TECHNOLOGIES THAT ARE MORE EFFECTIVE OR COMMERCIALLY ATTRACTIVE THAN OUR PRODUCTS. We expect to encounter increased competition from both established and development-stage companies that continually enter our market. We anticipate that these competitors will include: - companies developing and marketing life sciences research tools, - health care companies that manufacture laboratory-based tests and analyzers, - diagnostic and pharmaceutical companies, and - companies developing drug discovery technologies. 7

Currently, our principal competition comes from established companies that provide products which perform many of the same functions for which we market our products. Our competitors may develop or market products that are more effective or commercially attractive than our current or future products. Many of our competitors have substantially greater financial, operational, marketing and technical resources than we do. Moreover, these competitors may offer broader product lines and tactical discounts, and may have greater name recognition. In addition, we may face competition from new entrants into our field. We may not have the financial resources, technical expertise or marketing, distribution or support capabilities to compete successfully in the future. IF WE ARE UNABLE TO EFFECTIVELY PROTECT OUR INTELLECTUAL PROPERTY, THIRD PARTIES MAY USE OUR TECHNOLOGY, WHICH WOULD IMPAIR OUR ABILITY TO COMPETE IN OUR MARKETS. Our continued success will depend in significant part on our ability to obtain and maintain meaningful patent protection for our products throughout the world. Patent law relating to the scope of claims in the technology fields in which we operate is still evolving. The degree of future protection for our proprietary rights is uncertain. We own ten U.S. patents and have four patent applications pending in the U.S. We also own numerous U.S. registered trademarks and trade names and have applications for the registration of trademarks and trade names pending. We rely on patents to protect a significant part of our intellectual property and to enhance our competitive position. However, our presently pending or future patent applications may not issue as patents, and any patent previously issued to us may be challenged, invalidated, held unenforceable or circumvented. Furthermore, the claims in patents which have been issued or which may be issued to us in the future may not be sufficiently broad to prevent third parties from producing competing products similar to our products. In addition, the laws of various foreign countries in which we compete may not protect our intellectual property to the same extent as do the laws of the United States. If we fail to obtain adequate patent protection for our proprietary technology, our ability to be commercially competitive will be materially impaired. In addition to patent protection, we also rely on protection of trade secrets, know-how and confidential and proprietary information. To maintain the confidentiality of trade secrets and proprietary information, we generally seek to enter into confidentiality agreements with our employees, consultants and strategic partners upon the commencement of a relationship with us. However, we may not obtain these agreements in all circumstances. In the event of unauthorized use or disclosure of this information, these agreements, even if obtained, may not provide meaningful protection for our trade secrets or other confidential information. In addition, adequate remedies may not exist in the event of unauthorized use or disclosure of this information. The loss or exposure of our trade secrets and other proprietary information would impair our competitive advantages and could have a material adverse effect on our operating results, financial condition and future growth prospects. WE MAY BE INVOLVED IN LAWSUITS TO PROTECT OR ENFORCE OUR PATENTS WHICH WOULD BE EXPENSIVE AND TIME-CONSUMING. In order to protect or enforce our patent rights, we may initiate patent litigation against third parties. We may also become subject to interference proceedings conducted in the patent and trademark offices of various countries to determine the priority of inventions. Several of our products are based on patents which are closely surrounded by patents held by competitors or potential competitors. As a result, we believe there is a greater likelihood of a patent dispute than would be expected if our patents were not closely surrounded by other patents. The defense and prosecution, if necessary, of intellectual property suits, interference proceedings and related legal and administrative proceedings would be costly and divert our technical and management personnel from their normal responsibilities. We may not prevail in any of these suits. An adverse determination of any litigation or defense proceedings could put our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing. 8

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. For example, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments in the litigation. Securities analysts or investors may perceive these announcements to be negative, which could cause the market price of our stock to decline. OUR SUCCESS WILL DEPEND PARTLY ON OUR ABILITY TO OPERATE WITHOUT INFRINGING ON OR MISAPPROPRIATING THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS. We may be sued for infringing on the intellectual property rights of others, including the patent rights, trademarks and trade names of third parties. Intellectual property litigation is costly and the outcome is uncertain. If we do not prevail in any intellectual property litigation, in addition to any damages we might have to pay, we could be required to stop the infringing activity, or obtain a license to or design around the intellectual property in question. If we are unable to obtain a required license on acceptable terms, or are unable to design around any third party patent, we may be unable to sell some of our products and services, which could result in reduced revenue. AmiKa Corporation, whose assets we purchased in July 2000, has received and responded to correspondence from counsel to a third party competitor regarding the possible infringement by it of a patent and other pending patent applications held by such third party. Because this competitor has not pursued this matter since AmiKa's reply on June 7, 2000 in which AmiKa stated that it did not believe it was infringing on this competitor's patents, we believe that this matter has been concluded. However, we cannot assure you that this third party competitor will not assert these or similar claims in the future. We do not currently derive a significant portion of our revenue from products which depend on the intellectual property related to this alleged infringement. CHANGES IN ACCOUNTING FOR GOODWILL AMORTIZATION MAY HAVE A MATERIAL ADVERSE AFFECT ON US. We currently amortize goodwill purchased in our acquisitions on a straight line basis ranging from 5 to 15 years. At September 30, 2000, we had unamortized goodwill of $9.1 million, or 39.4% of total assets. Any changes in accounting rules under generally accepted accounting principles that reduce the period over which we may amortize goodwill may have an adverse effect on our ability to consummate future acquisitions and our financial results. A shorter goodwill amortization period would increase annual amortization expense and reduce our net income over the amortization period. In addition, we continually evaluate whether any portion of the remaining balance of goodwill may not be recoverable. If it is determined in the future that a portion of our goodwill is impaired, we may be required to write off that portion of our goodwill which would have an adverse effect on our net income for the period in which the write off occurs. WE ARE DEPENDENT UPON OUR LICENSED TECHNOLOGIES AND MAY NEED TO OBTAIN ADDITIONAL LICENSES IN THE FUTURE TO OFFER OUR PRODUCTS AND REMAIN COMPETITIVE. We have licensed key components of our technologies from third parties. If these agreements were to terminate prematurely or if we breach the terms of any licenses or otherwise fail to maintain our rights to these technologies, we may lose the right to manufacture or sell our products. In addition, we may need to obtain licenses to additional technologies in the future in order to keep our products competitive. If we fail to license or otherwise acquire necessary technologies, we may not be able to develop new products that we need to remain competitive. 9

MANY OF OUR CURRENT AND POTENTIAL CUSTOMERS ARE FROM THE PHARMACEUTICAL AND BIOTECHNOLOGY INDUSTRIES AND ARE SUBJECT TO RISKS FACED BY THOSE INDUSTRIES. We derive a substantial portion of our revenues from pharmaceutical and biotechnology companies. We expect that pharmaceutical and biotechnology companies will continue to be our major source of revenues for the foreseeable future. As a result, we are subject to risks and uncertainties that affect the pharmaceutical and biotechnology industries, such as pricing pressures as third-party payers continue challenging the pricing of medical products and services, government regulation, ongoing consolidation and uncertainty of technological change, and to reductions and delays in research and development expenditures by companies in these industries. In particular, several proposals are being contemplated by lawmakers in the United States to extend the federal Medicare program to include reimbursement for prescription drugs. Many of these proposals involve negotiating decreases in prescription drug prices or imposing price controls on prescription drugs. If appropriate reimbursement cannot be obtained, it could result in our customers purchasing fewer products from us as they reduce their research and development expenditures. In addition, we are dependent, both directly and indirectly, upon general health care spending patterns, particularly in the research and development budgets of the pharmaceutical and biotechnology industries, as well as upon the financial condition of various governments and government agencies. Many of our customers, including universities, government research laboratories, private foundations and other institutions, obtain funding for the purchase of our products from grants by governments or government agencies. There exists the risk of a potential decrease in the level of governmental spending allocated to scientific and medical research which could substantially reduce or even eliminate these grants. If government funding necessary to purchase our products were to decrease, our business and results of operations could be materially adversely affected. OUR BUSINESS IS SUBJECT TO ECONOMIC, POLITICAL AND OTHER RISKS ASSOCIATED WITH INTERNATIONAL REVENUES AND OPERATIONS. Since we manufacture and sell our products worldwide, our business is subject to risks associated with doing business internationally. Our revenues from our non-U.S. operations represented approximately 69% of our total revenues for the nine months ended September 30, 2000. We anticipate that revenue from international operations will continue to represent a substantial portion of our total revenues. In addition, a number of our manufacturing facilities and suppliers are located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including: - changes in foreign currency exchange rates, which resulted in a foreign currency loss of $456,000 for the nine months ended September 30, 2000, - changes in a specific country's or region's political or economic conditions, including Western Europe, in particular, - trade protection measures and import or export licensing requirements, - potentially negative consequences from changes in tax laws affecting our ability to expatriate profits, - difficulty in staffing and managing widespread operations, and - unfavorable labor regulations applicable to our European operations, such as the unenforceability of non-competition agreements in the United Kingdom. 10

WE MAY LOSE MONEY WHEN WE EXCHANGE FOREIGN CURRENCY RECEIVED FROM INTERNATIONAL REVENUES INTO U.S. DOLLARS. For the nine months ended September 30, 2000, approximately 69% of our business was conducted in currencies other than the U.S. dollar, which is our reporting currency. As a result, currency fluctuations among the U.S. dollar and the currencies in which we do business have caused and will continue to cause foreign currency transaction gains and losses. Currently, we attempt to manage foreign currency risk through the matching of assets and liabilities. In the future, we may undertake to manage foreign currency risk through additional hedging methods. We recognize foreign currency gains or losses arising from our operations in the period incurred. We cannot guarantee that we will be successful in managing foreign currency risk or in predicting the effects of exchange rate fluctuations upon our future operating results because of the number of currencies involved, the variability of currency exposure and the potential volatility of currency exchange rates. IF WE ENGAGE IN ANY ACQUISITION, WE WILL INCUR A VARIETY OF COSTS, AND MAY NEVER REALIZE THE ANTICIPATED BENEFITS OF THE ACQUISITION. Our business strategy includes the future acquisition of businesses, technologies, services or products that we believe are a strategic fit with our business. If we do undertake any acquisition, the process of integrating an acquired business, technology, service or product may result in unforeseen operating difficulties and expenditures and may absorb significant management attention that would otherwise be available for ongoing development of our business. Moreover, we may fail to realize the anticipated benefits of any acquisition. Future acquisitions could reduce your ownership and could cause us to incur debt, expose us to future liabilities and result in amortization expenses related to goodwill and other intangible assets. IF WE FAIL TO RETAIN OUR KEY PERSONNEL AND HIRE, TRAIN AND RETAIN QUALIFIED EMPLOYEES, WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY, WHICH COULD RESULT IN REDUCED REVENUE. Our success is highly dependent on the continued services of key management, technical and scientific personnel. Our management and other employees may voluntarily terminate their employment with us at any time upon short notice. The loss of the services of any member of our senior management team, including our Chief Executive Officer, Chane Graziano, and our President, David Green, or any of our technical or scientific staff may significantly delay or prevent the achievement of product development and other business objectives. We maintain key person life insurance on Messrs. Graziano and Green. Our future success will also depend on our ability to identify, recruit and retain additional qualified scientific, technical and managerial personnel. Competition for qualified personnel in the technology area is intense, and we operate in several geographic locations where labor markets are particularly competitive, including Boston, Massachusetts and London and Cambridge, England, and where demand for personnel with these skills is extremely high and is likely to remain high. As a result, competition for qualified personnel is intense, particularly in the areas of information technology, engineering and science and the process of hiring suitably qualified personnel is often lengthy. If we are unable to hire and retain a sufficient number of qualified employees, our ability to conduct and expand our business could be seriously reduced. WE PLAN SIGNIFICANT GROWTH, AND THERE IS A RISK THAT WE WILL NOT BE ABLE TO MANAGE THIS GROWTH. Our success will depend on the expansion of our operations. Effective growth management will place increased demands on our management, operational and financial resources. To manage our growth, we must expand our facilities, augment our operational, financial and management systems, and hire and train additional qualified personnel. Our failure to manage this growth effectively could impair our ability to generate revenue or could cause our expenses to increase more rapidly than revenue, resulting in operating losses. 11

OUR EXISTING STOCKHOLDERS WILL HAVE SUBSTANTIAL INFLUENCE OVER MATTERS REQUIRING A STOCKHOLDER VOTE. Following the completion of this offering, our current stockholders will beneficially own or control approximately 74% of the outstanding shares of our common stock. If all of these stockholders were to vote together as a group, they would have the ability to elect our board of directors and control the outcome of stockholder votes, including votes concerning by-law amendments and possible mergers, corporate control contests and other significant corporate transactions. In addition, this concentration of ownership may delay or prevent a change of control of our company at a premium price if these stockholders oppose it. The interests of these stockholders may not always coincide with our interests as a company or the interests of other stockholders. BECAUSE OUR STOCK PRICE IS LIKELY TO BE HIGHLY VOLATILE, OUR STOCK PRICE COULD EXPERIENCE SUBSTANTIAL DECLINES AND OUR MANAGEMENT'S ATTENTION MAY BE DIVERTED FROM MORE PRODUCTIVE TASKS. The market price of our common stock is likely to be volatile and could decline, perhaps substantially, following this offering in response to various factors, many of which are beyond our control, including: - technological innovations by competitors or in competing technologies, - revenues and operating results fluctuating or failing to meet the expectations of securities analysts or investors in any quarter, - downward revisions in securities analysts' estimates, - conditions or trends in the biotechnology and pharmaceutical industries, - announcements by us of significant acquisitions or financings or changes in strategic partnerships, and - a decrease in the demand for our common stock. In addition, the stock market in general, and the Nasdaq National Market and the biotechnology industry market in particular, have experienced significant price and volume fluctuations that at times have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. In the past, securities class action litigation has often been instituted following periods of volatility in the market price of a company's securities. A securities class action suit against us could result in substantial costs, potential liabilities and the diversion of our management's attention and resources. PROVISIONS OF DELAWARE LAW AND OF OUR CHARTER AND BY-LAWS MAY MAKE A TAKEOVER MORE DIFFICULT WHICH COULD CAUSE OUR STOCK PRICE TO DECLINE. Provisions in our certificate of incorporation and by-laws and in the Delaware corporate law may make it difficult and expensive for a third party to pursue a tender offer, change in control or takeover attempt which is opposed by our management and board of directors. Public stockholders who might desire to participate in such a transaction may not have an opportunity to do so. We also have a staggered board of directors which makes it difficult for stockholders to change the composition of the board of directors in any one year. These anti-takeover provisions could substantially impede the ability of public stockholders to change our management and board of directors. Such provisions may also limit the price that investors might be willing to pay for shares of our common stock in the future. 12

FAILURE TO RAISE ADDITIONAL CAPITAL OR GENERATE THE SIGNIFICANT CAPITAL NECESSARY TO EXPAND OUR OPERATIONS AND INVEST IN NEW PRODUCTS COULD REDUCE OUR ABILITY TO COMPETE AND RESULT IN LOWER REVENUE. We anticipate that our existing capital resources and the net proceeds from this offering will enable us to maintain currently planned operations for at least the next two years. However, we premise this expectation on our current operating plan, which may change as a result of many factors, including market acceptance of our new products and future opportunities with collaborators. Consequently, we may need additional funding sooner than anticipated. Our inability to raise capital could seriously harm our business and product development efforts. If we raise additional funds through the sale of equity or convertible debt or equity-linked securities, your percentage ownership in the company will be reduced. In addition, these transactions may dilute the value of our outstanding stock. We may issue securities that have rights, preferences and privileges senior to our common stock. If we raise additional funds through collaborations or licensing arrangements, we may relinquish rights to certain of our technologies or products, or grant licenses to third parties on terms that are unfavorable to us. We may be unable to raise additional funds on terms acceptable to us. If future financing is not available to us or is not available on terms acceptable to us, we may have to curtail or cease operations. SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING COULD ADVERSELY AFFECT OUR STOCK PRICE. The market price of our common stock could decline as a result of sales of shares by our existing stockholders after this offering, or the perception that such sales will occur. These sales also might make it difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. After this offering, we will have 24,782,422 shares of common stock outstanding. Of these shares, all of the shares sold in this offering will be freely tradeable. All of our existing stockholders have executed lock-up agreements. Those lock-up agreements restrict all of our existing stockholders from selling, pledging or otherwise disposing of their shares for a period of 180 days after the date of this prospectus without the prior written consent of Thomas Weisel Partners LLC. However, Thomas Weisel Partners LLC may, in its sole discretion, release all or any portion of the common stock from the restrictions of the lock-up agreements. In addition, after this offering, we also intend to register 3,750,000 shares of common stock for issuance under our 2000 Stock Option and Incentive Plan and 500,000 shares under our Employee Stock Purchase Plan. WE WILL HAVE BROAD DISCRETION AS TO THE USE OF THE PROCEEDS FROM THIS OFFERING AND MAY USE THE PROCEEDS IN A MANNER WITH WHICH YOU DISAGREE. Our board of directors and our management will have broad discretion over the use of the net proceeds of this offering. You may disagree with the judgment of our board of directors and our management regarding the application of the proceeds of this offering. We intend to use a majority of the proceeds from this offering for payment of existing debt, redemption of our series A preferred stock, working capital and general corporate purposes and to fund potential acquisitions, if any. Because of the number and variability of factors that determine our use of the net proceeds from this offering, we cannot assure you that our actual use will not vary substantially from our currently planned uses. Initially, we intend to invest the net proceeds from this offering in income producing, investment grade securities. FUTURE ISSUANCE OF OUR PREFERRED STOCK MAY DILUTE THE RIGHTS OF OUR COMMON STOCKHOLDERS. Our board of directors has the authority to issue up to 5,000,000 shares of preferred stock and to determine the price, privileges and other terms of these shares. The board of directors may exercise this authority without any further approval of our stockholders. The rights of the holders of common stock may be adversely affected by the rights of future holders of our preferred stock. 13

YOU WILL NOT RECEIVE CASH DIVIDENDS ON YOUR INVESTMENT IN OUR COMMON STOCK. We intend to retain all of our earnings to finance the development and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. Moreover, our ability to declare and pay cash dividends on our common stock is restricted by covenants in our senior credit facility and in the indenture governing our senior subordinated notes. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future. AN ACTIVE TRADING MARKET FOR OUR COMMON STOCK MAY NOT DEVELOP. Prior to this offering, there has been no public market for our common stock. Although we expect our common stock to be quoted on the Nasdaq National Market, an active trading market for our shares may not develop or be sustained following this offering. You may not be able to resell your shares at prices equal to or greater than the initial public offering price. The initial public offering price will be determined through negotiations between us and the underwriters and may not be indicative of the market price for these shares following this offering. You should read "Underwriting" for a discussion of the factors to be considered in determining the initial public offering price. 14

USE OF PROCEEDS We estimate that the net proceeds we will receive from the sale of 6,250,000 shares of common stock will be approximately $68.3 million, or approximately $78.7 million if the underwriters fully exercise their over-allotment option, at the assumed offering price of $12.00 per share, in each case after deducting estimated underwriting discounts, commissions and offering expenses payable by us. We will not receive any proceeds from the sale of shares by our president as a selling stockholder in this offering. The principal purposes of this offering are as follows: - to permit us to repay approximately $665,000 in subordinated debt and $9.6 million under our credit facility, - to permit us to redeem our series A redeemable preferred stock at a cost of approximately $1.5 million, - to provide us with funds to complete potential acquisitions and enhance our ability to use our common stock as consideration for potential acquisitions, - to increase our equity capital and facilitate our future access to public equity markets, - to increase our working capital, and - to increase funds available for general corporate purposes. Except for the payment of existing debt and the redemption of preferred stock listed above, the use of proceeds has not been specifically identified or allocated due to the flexible nature of our planning process and the constantly changing nature of our industry. We will retain broad discretion in the allocation and use of the net proceeds of this offering. Pending the uses described above, we intend to invest the remaining net proceeds from this offering in short-term, investment grade, interest-bearing securities. Our subordinated debt bears interest at an annual rate of 13.0% and matures upon the consummation of this offering. All of the subordinated debt will be retired out of the proceeds of this offering. Our credit facility consists of two term loans and a revolving credit line. One term loan and the revolving line of credit mature in January 2002. The other term loan matures in June 2004. The interest rate for the credit facility is equal to our lender's base rate plus 1.0%. This interest rate was 10.5% at October 15, 2000. In July 2000, we increased our borrowings under our credit facility by $2.5 million to finance the acquisition of AmiKa Corporation. All of our outstanding indebtedness under our credit facility will be repaid out of the proceeds of this offering. DIVIDEND POLICY We have never declared or paid dividends on our common stock in the past and do not intend to pay dividends on our common stock in the foreseeable future. Any future determination to pay dividends will be at the discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements and other factors the board of directors deems relevant. In addition, our existing credit facility does not permit us to pay cash dividends, and any future credit facilities may not permit us to pay cash dividends. 16

CAPITALIZATION The following table describes our capitalization as of September 30, 2000: - on an actual basis assuming the filing of an amended certificate of incorporation to increase the number of authorized shares of common stock, - on a pro forma basis to give effect to the conversion of all outstanding shares of convertible preferred stock into an aggregate of 955,935 shares of common stock, the exercise of all outstanding warrants for an aggregate of 8,509,905 shares of common stock upon the closing of this offering and the filing of our amended and restated certificate of incorporation prior to the effective date of this offering, and - on a pro forma as adjusted basis to reflect the sale of 6,250,000 shares of common stock by us in this offering at an assumed initial offering price of $12.00 per share, after deducting estimated underwriting discounts, commissions and offering expenses payable by us and the application of the net proceeds therefrom.

The above table also assumes no exercise of the underwriters' over-allotment option. 17

DILUTION Our pro forma net tangible book value as of September 30, 2000, was approximately $(3.0) million, or $(0.19) per share of common stock. Pro forma net tangible book value per share represents the amount of our total pro forma tangible assets less total liabilities divided by the pro forma number of shares of common stock outstanding. After giving effect to the issuance and sale by us of 6,250,000 shares of common stock offered by this prospectus at an assumed initial offering price of $12.00 per share and after deducting estimated underwriting discounts, commissions and offering expenses payable by us, our pro forma net tangible book value as of September 30, 2000 would have been $65 million, or $2.63 per share. This represents an immediate increase in the pro forma net tangible book value of $2.82 per share to existing stockholders and an immediate dilution of $9.37 per share to new stockholders in this offering illustrated by the following table: Assumed initial public offering price per share........... $ 12.00 Pro forma net tangible book value per share before this offering.............................................. $(0.19) Increase per share attributable to new stockholders..... 2.82 ------ Pro forma net tangible book value per share after the offering................................................ 2.63 -------- Dilution per share to new investors....................... $ 9.37 ======== The following table sets forth on a pro forma basis as of September 30, 2000, the number of shares of common stock purchased from us, the total consideration paid and the average price per share paid by existing and new stockholders before deducting underwriting discounts, commissions and offering expenses payable by us: SHARES PURCHASED TOTAL CONSIDERATION --------------------- ---------------------- AVERAGE PRICE NUMBER PERCENT AMOUNT PERCENT PER SHARE ---------- -------- ----------- -------- ------------- Existing stockholders......... 18,532,422 74.8% $ 2,558,106 3.3% $ 0.14 New stockholders....... 6,250,000 25.2 75,000,000 96.7 12.00 ---------- ------ ----------- ----- Total.............. 24,782,422 100.0% $77,558,106 100.0% ========== ====== =========== ===== The foregoing discussion and tables assume no issuance of shares by us pursuant to the underwriters' over-allotment option and no exercise of any stock options outstanding. As of September 30, 2000, there were options outstanding to purchase a total of approximately 598,612 shares of common stock with a weighted average exercise price of $1.00 per share. To the extent that any of these options are exercised, your investment will be further diluted. In addition, we may grant more options in the future under our stock plans. 18

SELECTED FINANCIAL DATA You should read the following selected consolidated financial data in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our consolidated financial statements and related notes included elsewhere in this prospectus. The statement of operations data for the years ended December 31, 1997, 1998 and 1999 and for the nine-month period ended September 30, 2000 and the balance sheet data at December 31, 1998 and 1999 and September 30, 2000 are derived from our audited consolidated financial statements appearing elsewhere in this prospectus. The balance sheet data at December 31, 1997 and 1996, and the statement of operations data for the period from March 15, 1996 to December 31, 1996 are derived from our audited consolidated financial statements not included in this prospectus. The statement of operations data for the year ended December 31, 1995 and for the period from January 1, 1996 to March 14, 1996 and the balance sheet data at December 31, 1995 represents data of a predecessor company and are derived from their unaudited consolidated financial statements not included in this prospectus. The interim statement of operations data for the nine-month period ended September 30, 1999 are derived from our unaudited consolidated interim financial statements appearing elsewhere in this prospectus which, in the opinion of management, have been prepared on the same basis as the audited consolidated financial statements and reflect all adjustments necessary for a fair presentation of that data.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS YOU SHOULD READ THE FOLLOWING DISCUSSION IN CONJUNCTION WITH OUR CONSOLIDATED FINANCIAL STATEMENTS, THE RELATED NOTES AND OTHER FINANCIAL INFORMATION APPEARING ELSEWHERE IN THIS PROSPECTUS. OVERVIEW We are a provider of innovative, enabling tools for drug discovery research at pharmaceutical and biotechnology companies, universities and government research laboratories. We focus on two critical bottlenecks in the drug discovery process, proteomics during the target validation stage of the drug discovery process and ADMET screening during the secondary screening stage of the drug discovery process. Our proteomics products consist of tools that allow our customers to purify and analyze proteins. Our ADMET screening products are tools that enable our customers to test drug candidates to determine their absorption, distribution, metabolism, elimination and toxicology properties prior to conducting costly clinical trials. In providing tools for drug discovery generally, we have established a significant base business and have achieved brand recognition through our sale of precision pumps, ventilators and tissue/organ systems. Since our reorganization in 1996, we have built upon our base business and brand recognition by adding new technologies within the areas of proteomics and ADMET screening. Specifically, we have acquired the following product lines, businesses and technologies: - In June 1998, we acquired products for cell injection systems from Medical Systems Corporation for $1.0 million in cash, - In March 1999, we acquired Biochrom, which develops and manufactures DNA/RNA/protein calculators, spectrophotometers, amino acid analyzers and related consumables in the United Kingdom, from Pharmacia Biotech (Biochrom) Ltd for $7.0 million in cash, - In March 1999, we entered into an exclusive license for the technology underlying our ScanTox in vitro toxicology testing product for $25,000 in cash and ongoing royalties and licensing fee payments, - In September 1999, we acquired products for intracellular research from Clark Electromedical Instruments for $349,000 in cash, - In November 1999, we acquired our NaviCyte diffusion chamber systems product for drug absorption testing from a subsidiary of Trega Biosciences for $390,000 in cash and future royalties, - In November 1999, we acquired substantially all the assets and certain liabilities of Hugo Sachs Elektronik, consisting primarily of products for organ testing, for $568,000 in cash, - In May 2000, we acquired certain assets of Biotronik, consisting primarily of products for amino acid analysis, for $469,000 in cash, and - In July 2000, we acquired substantially all the assets of AmiKa Corporation consisting of purification tips, spin columns, a 96 well drug binding assay and related technology and intellectual property for $3.1 million in cash. We have also entered into a non-binding letter of intent to acquire substantially all the assets and certain liabilities of a company that produces tools for toxicity testing. The non-binding letter of intent provides for an initial cash payment of $200,000, a second cash payment of $100,000 approximately one month following the initial cash payment and additional contingent payments and royalty payments based on future sales of the acquired products. This non-binding letter of intent will expire on 20

December 15, 2000. We are working to complete this acquisition by that date although we cannot be certain that this acquisition will be completed by that date or at all. REVENUES. We generate revenues by selling instruments, devices and consumables through our catalog, our distributors and our website. We distribute our catalog initially in a series of bulk mailings, first to our existing customers, followed by mailings to targeted markets of potential customers. Distribution is then made singly to potential and existing customers through direct mail, trade shows and telephone inquiries over the life of the catalog. From time to time, we provide catalog supplements that promote selected areas of our catalog or new products to targeted subsets of our customer base. Future distributions of our catalog will be determined primarily by the incidence of new product introductions, which cannot be predicted. Our customers are end user research scientists at pharmaceutical and biotechnology companies, universities and government laboratories. Revenue from catalog sales in any period is a function of time elapsed since the last mailing of the catalog, the number of catalogs mailed and the number of new items included in the catalog. Catalog sales tend to increase immediately following a mailing and level off or decline slightly from the increased level until the next mailing, which repeats the cycle. For the nine months ended September 30, 2000, approximately 82% of our revenues were derived from products we manufacture. The remaining 18% of our revenues were derived from complementary products we distribute in order to provide researchers with a single source for all equipment needed to conduct a particular experiment. Approximately one-half of our revenues are derived through catalog sales and through reference to our website, which is an electronic version of our catalog. We do not currently have the capability to accept purchase orders through our website. For the nine months ended September 30, 2000, approximately 69% of our revenues were derived from sales made by our non-U.S. operations. A majority of our international sales during this period consisted of sales to Amersham Pharmacia Biotech, the distributor for our spectrophotometers and amino acid analyzers. Amersham Pharmacia Biotech distributes these products to customers around the world from its distribution center in Upsalla, Sweden, including to many customers located in the United States. As a result, we believe our international sales would have been less as a percentage of our revenues for the nine months ended September 30, 2000 than indicated above if we had shipped our products directly to their end users. COST OF GOODS SOLD. Cost of goods sold includes material, labor and manufacturing overhead costs, obsolescence charges, packaging costs, warranty costs, shipping charges and royalties. Our costs of goods sold may vary over time based on the mix of products sold. We sell products that we manufacture and products that we purchase from third parties. The products that we purchase from third parties have lower margins because the profit is effectively shared with the original manufacturer. For the nine months ended September 30, 2000, our manufactured products had lower cost of goods sold. We anticipate that our manufactured products will continue to have a lower cost of goods sold for the forseeable future. GENERAL AND ADMINISTRATIVE EXPENSE. General and administrative expense consists primarily of salaries and other related costs for personnel in executive, finance, accounting, information technology and human relations functions. Other costs include facility costs, professional fees for legal and accounting services, and provision for doubtful accounts. SALES AND MARKETING EXPENSE. Sales and marketing expense consists primarily of salaries and related expenses for personnel in sales, marketing and customer support functions. We also incur costs for trade shows, demonstration equipment, public relations and marketing materials, consisting primarily of the printing and distribution of our 1,000 page catalog and the maintenance of our web site. We may from time to time in the future expand our marketing efforts by employing additional technical marketing specialists in an effort to increase sales of selected categories of products in our catalog. 21

RESEARCH AND DEVELOPMENT EXPENSE. Research and development expense consists primarily of salaries and related expenses for personnel and capital resources used to develop and enhance our products. Other research and development expense includes fees paid to consultants and outside service providers, and material costs for prototype and test units. We expense research and development costs as incurred. We believe that significant investment in product development is a competitive necessity and plan to continue this investment in order to realize the potential of our new technologies for proteomics and ADMET. STOCK COMPENSATION EXPENSE. Stock compensation resulting from stock option grants to our employees represents the difference between the fair market value and the exercise price of the stock options on the date the stock options were granted for those options that are considered fixed awards. Stock compensation expense is also recorded for stock option grants that were considered variable awards as the number of shares to be acquired by employees was indeterminable at the date of grant. Deferred compensation on fixed awards is amortized as a charge to operations over the vesting period of the options. Based on grants in 2000, we incurred deferred compensation of $9.9 million and recognized deferred compensation expense of $3.3 million for the nine months ended September 30, 2000. Since our reorganization in 1996, we have experienced substantial revenue growth. In the future we intend to introduce new products for proteomics and ADMET research that support emerging and potentially large markets. In order to support the anticipated growth of these new products, we may expand our product development and sales and marketing activities. In the event we pursue activities which increase our product development and sales and marketing expenses, operating results will be adversely affected if revenues do not increase proportionately. If revenues are below expectations, our business, operating results and financial condition are likely to be materially and adversely affected. Net income may be disproportionately affected by a reduction in revenues as a relatively smaller amount of our expenses vary with changes in our revenues. As a result, we believe that period-to-period comparisons of our results of operations are not necessarily meaningful and should not be relied upon as indications of future performance. NINE MONTHS ENDED SEPTEMBER 30, 2000 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30, 1999 REVENUES. Revenues increased $3.6 million, or 20%, to $22.1 million in 2000 from $18.5 million in 1999. Excluding the impact of changes in foreign currency exchange rates, revenues based on 1999 rates would have been approximately $22.8 million in 2000. Approximately $1.1 million of the $3.6 million increase, or 31%, was attributable to the full period effect of revenues from the acquisition of our Biochrom subsidiary in March 1999 net of exchange rate effects of $508,000. The balance of the increase was attributable to $2.5 million of revenue from product line acquisitions made in the second half of 1999 partially offset by the cyclical nature of catalog sales of traditional products. During the year preceding the mailing of a new catalog in April 2000, traditional products were not promoted because we were concentrating on the acquisition of new products or businesses as well as the development of the new catalog to include these newly acquired products. COST OF GOODS SOLD. Cost of goods sold increased $2.1 million, or 23%, to $11.5 million in 2000 from $9.4 million in 1999. The increase in cost of goods sold as a percentage of revenues was due to slightly higher cost of goods sold on acquired product lines and for our Biochrom subsidiary acquired in March 1999. Our Biochrom subsidiary experiences lower revenues and correspondingly lower general and administration and sales and marketing expenses relative to cost of goods sold as a consequence of marketing its products primarily through a distributor. GENERAL AND ADMINISTRATIVE EXPENSE. General and administrative expense increased $807,000, or 28%, to $3.7 million in 2000 from $2.9 million in 1999 due primarily to the full period effect of Biochrom as well as increased support for operations. 22

SALES AND MARKETING EXPENSE. Sales and marketing expense increased $517,000, or 28%, to $2.4 million in 2000 from $1.8 million in 1999. The increase was primarily due to expenses of acquisitions as well as the addition of marketing personnel and additional catalog costs. As a percentage of revenues, marketing and sales expense was 11% in 2000 and 10% in 1999. This increasing percentage reflects the addition of marketing personnel to promote newly acquired technology. In the future we may add employees to expand selected categories of our catalog as well as to expand the capabilities of our web site and integrate it into our business planning and processes. RESEARCH AND DEVELOPMENT EXPENSE. Research and development spending increased $367,000, or 44%, to $1.2 million in 2000 from $841,000 in 1999. The increase in research and development expense resulted from expenses of acquisitions, spending on product enhancement and new product development, primarily on ScanTox in vitro toxicology testing and other core technology. As a percentage of revenues, research and development expense was 6% in 2000 and 5% in 1999. This increasing percentage reflects expanded efforts on ADMET testing products. STOCK COMPENSATION EXPENSE. We recorded $13.3 million of stock compensation expense in the nine months ended September 30, 2000. In connection with the grant of stock options to employees in 2000, we recorded deferred compensation of approximately $3.3 million and will recognize approximately $6.6 million of additional expense over the remaining vesting life of the options. In addition, in the third quarter of 2000, we also recorded $10.0 million of stock compensation expense in connection with options granted in 1996 and 1999. In 1999, we recorded $937,000 of stock compensation expense related to these 1996 and 1999 option grants. AMORTIZATION OF GOODWILL. Amortization of goodwill was $423,000 in 2000 and $252,000 in 1999. The increase is the result of amortizing additional goodwill incurred in connection with our acquisitions in 2000. OTHER EXPENSE, NET. Other expense, net, was $72.1 million in 2000 compared to $7.9 million in 1999. Other expense, net, included a non-cash charge for common stock warrant interest expense of $70.9 million in 2000 and $7.4 million in 1999. This amount represents the difference between the fair value of the warrant for financial reporting purposes and its exercise price. This liability represents the right of warrant holders to require us to pay cash equal to the fair market value of the warrants in exchange for the warrants, or any common stock from the exercise of the warrants, beginning March 15, 2002. Effective with this offering, the warrants will be exercised for common stock and the right to be paid cash will terminate. The liability previously recorded will become part of common stock and additional-paid-in capital, and no additional liability will be incurred with respect to these warrants. Net interest expense increased $186,000, or 40%, to $655,000 in 2000 from $468,000 in 1999. The increase resulted primarily from higher debt balances in 2000, which were incurred to finance acquisitions. INCOME TAXES. The Company's effective income tax rates were 39% for 2000 and 33% for 1999 notwithstanding the impacts for common stock warrant interest expense and stock compensation expense in excess of allowable tax benefits on exercise of options, which are not deductible for income tax purposes. The increase in the rate is principally due to certain blended higher foreign statutory jurisdiction income tax rates. The effective income tax rates may change compared to the remainder of each respective calendar year if operating results differ significantly from the interim results. YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 1998 REVENUES. Revenues increased $14.0 million, or 115%, to $26.2 million in 1999 from $12.2 million in 1998. Approximately $12.2 million, or 87%, of the increase was derived from the March 1999 acquisition of Biochrom. Excluding the impact of changes in foreign currency exchange rates, revenues based on 1998 rates would have been approximately $26.3 million in 1999. Revenues from our existing 23

business increased $1.8 million, or 15%, to $14.0 million in 1999 from $12.2 million in 1998. The increase was attributable to full year revenues of $570,000 from the products acquired from Medical Systems in June 1998, increased sales resulting from our expanded direct marketing efforts on traditional products of $884,000, which included hiring additional marketing staff, producing a CD-ROM of our catalog, and creating and installing an electronic version of our catalog on our website, with the balance due to revenues from product lines acquired in the second half of 1999. COST OF GOODS SOLD. Cost of goods sold increased $8.2 million, or 153%, to $13.5 million in 1999 from $5.4 million in 1998. As a percentage of revenues, cost of goods sold increased to 52% in 1999 from 44% in 1998. The increase in cost of goods sold in 1999 was primarily the result of the acquisition of Biochrom. The percentage increase was also the result of Biochrom, which experiences higher costs of goods sold as a percentage of revenues due to the marketing of its products primarily through a distributor, which receives a discount to the list price that is calculated to cover the distributor's costs and profits. GENERAL AND ADMINISTRATIVE EXPENSE. General and administration expense increased $5.1 million, or 221%, to $7.4 million in 1999 from $2.3 million in 1998. Biochrom accounted for $1.1 million, or 22%, of the increase. Also in 1999, $3.3 million was recorded as non-cash compensation expense from options granted in 1996. Excluding the Biochrom acquisition and the compensation expense, expenses increased $800,000, or 35%, to $3.1 million in 1999 from $2.3 million in 1998. The increase was due to the need to support expanding operations. As a percentage of revenues, general and administration expense increased to 28% in 1999 from 19% in 1998. SALES AND MARKETING EXPENSE. Sales and marketing expense increased $727,000, or 42%, to $2.4 million in 1999 from $1.7 million in 1998. Biochrom accounted for $608,000, or 84%, of the increase. Excluding the Biochrom acquisition, expenses increased $119,000, or 7%, to $1.8 million in 1999 from $1.7 million in 1998. The increase was due to expanded direct marketing efforts and the full year effect of support for the products acquired in June 1998. As a percentage of revenues, sales and marketing expense decreased to 9% in 1999 from 14% in 1998. The decrease in sales and marketing expense as a percentage of revenues was primarily due to the acquisition of Biochrom, which has lower sales and marketing expense because those expenses are primarily borne by its distributor. RESEARCH AND DEVELOPMENT EXPENSE. Research and development spending increased $863,000 in 1999, or 266%, to $1.2 million from $325,000 in 1998. The acquisition of Biochrom contributed $577,000 to the increase. The balance of the increase was spending for development of our newly licensed ScanTox technology and expansion of our core drug screening products. As a percentage of revenues, research and development expense increased to 5% in 1999 from 3% in 1998. The increase in research and development expense as a percentage of revenues was primarily due to Biochrom, our employment of additional engineers and increased charges for outside services. AMORTIZATION OF GOODWILL. Amortization of goodwill was $368,000 in 1999 and $28,000 in 1998. The increase is the result of amortizing additional goodwill incurred in connection with our acquisitions in 1999 and the full year effect of the acquisition of the Medical Systems products in June 1998. OTHER EXPENSE, NET. Other expense, net was $30.5 million in 1999 compared to $1.6 million in 1998. Other expense, net, included a non-cash charge for common stock warrant interest expense of $29.7 million in 1999 and $1.4 million in 1998. Net interest expense increased $447,000, or 214%, to $656,000 in 1999 from $209,000 in 1999. The increase resulted primarily from higher debt balances in 1999, which were incurred to finance acquisitions. INCOME TAXES. The Company's effective income tax rates were 33% for 1999 and 35% for 1998 notwithstanding the impact for common stock warrant interest expense which is not deductible for 24

income tax purposes. The decrease in the rate is principally due to certain lower foreign statutory jurisdiction income tax rates, specifically the result of the acquisition of a United Kingdom subsidiary. YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997 REVENUES. Revenues increased $690,000, or 6%, to $12.2 million in 1998, from $11.5 million in 1997. The increase was due to the introduction of new products from the acquisition of Medical Systems in June 1998, which accounted for $510,000 of the increase, as well as growth in sales of existing products, primarily due to the issuance of two catalog supplements in 1998 compared to one supplement issued in 1997. COST OF GOODS SOLD. Cost of goods sold increased approximately $224,000, or 4%, to $5.4 million in 1998 from $5.1 million in 1997. As a percentage of revenues, cost of goods sold decreased to 44% in 1998 from 45% in 1997. The decrease was due to spreading manufacturing overhead across increased production relating to the products acquired with the purchase of Medical Systems. GENERAL AND ADMINISTRATIVE EXPENSE. General and administrative expense remained constant at $2.3 million from 1997 to 1998. As a percentage of revenues, general and administrative expense decreased to 19% in 1998 from 20% in 1997. The decrease in general and administrative expense as a percentage of revenues was primarily due to spreading general and administrative costs over a greater revenue base. SALES AND MARKETING EXPENSE. Sales and marketing expense increased $49,000, or 3%, to $1.7 million in 1998 from $1.7 million in 1997. As a percentage of revenues, sales and marketing expense decreased to 14% in 1998 from 15% in 1997. The decrease in sales and marketing expense as a percentage of revenues was primarily due to spreading sales and marketing costs over a greater revenue base. RESEARCH AND DEVELOPMENT EXPENSE. Research and development spending increased $118,000, or 57%, to $325,000 in 1998 from $206,000 in 1997. The increase in spending represented investments in product development and enhancement of the existing family of products. As a percentage of revenues, research and development expense increased to 3% in 1998 from 2% in 1997. AMORTIZATION OF GOODWILL. Amortization of goodwill consisted of a charge of $28,000 in 1998 resulting from the acquisition of Medical Systems. There was no corresponding charge in 1997. OTHER EXPENSES, NET. Other expenses, net were $1.6 million in 1998 compared to $330,000 in 1997. The increase was due primarily to a charge of $1.4 million for common stock warrant interest expense. INCOME TAXES. The Company's effective income tax rates were 35% for 1998 and 36% for 1997 notwithstanding the impact for common stock warrant interest expense which is not deductible for income tax purposes. The change in the tax rate is principally due to certain tax rates in foreign jurisdictions. LIQUIDITY AND CAPITAL RESOURCES Historically, we have financed our business through cash provided by operating activities, the issuance of common and preferred stock, and bank borrowings. Our liquidity requirements have arisen primarily from investing activities, including funding of acquisitions, payments on outstanding indebtedness, research and development expenditures, and capital expenditures. As of September 30, 2000, we had cash of $2.1 million. Since our reorganization in March 1996, we have raised $14.2 million, consisting of $2.5 million of preferred and common stock and $11.7 million of debt. As of September 30, 2000, we had $6.8 million in debt under a bank term loan, $478,000 in subordinated debt and $3.1 million outstanding under a $3.8 million revolving credit facility. 25

Our operating activities generated cash of $2.0 million in the first nine months of 2000, $2.9 million in fiscal 1999, $1.8 million in fiscal 1998 and $1.1 million in fiscal 1997. For all periods presented, operating cash flows were primarily due to operating results, including the full-year effect of acquisitions prior to non-cash charges, partially offset by working capital requirements. Working capital requirements were affected by acquisitions, which increased accounts receivable and inventory carrying amounts partially offset by increased amounts in accounts payable and accrued expenses. Our investing activities used cash of $4.7 million in the first nine months of 2000, $8.5 million in fiscal 1999, $1.4 million in fiscal 1998 and $653,000 in fiscal 1997. Cash has been used in the following technology and business acquisitions: - $469,000 for Biotronik's amino acid analysis systems business in May 2000, - $390,000 for the NaviCyte diffusion chamber systems product line in November 1999, - $568,000 for Hugo Sachs Elektronik in November 1999, - $349,000 for intracellular research products from Clark Electromedical Instruments in September 1999, - $7.0 million for Biochrom in March 1999, - $1.0 million for Medical Systems Corporation's cell injection systems business in June 1998, and - $3.1 million for substantially all the assets of AmiKa Corporation in July 2000. Our financing activities provided cash of $2.5 million for the first nine months of 2000 and $7.0 million in fiscal 1999, and used cash of $105,000 in fiscal 1998 and $874,000 in fiscal 1997. Financing cash flows consisted of borrowings under a revolving credit facility, long-term debt and the issuance of preferred stock. As of September 30, 2000, we had approximately $600,000 available under our revolving credit facility, subject to our ability to maintain compliance with all of the covenants contained in our revolving credit agreement. We were not in compliance with the net income covenants as of September 30, 2000 due to non-cash stock compensation and imputed interest on warrants. Our credit facility was amended to exclude the accounting treatment for stock option compensation and warrant interest expense. Prior to 1999, we had historically generated sufficient cash flow from operations to fund expenditures on capital equipment, debt service, equity transactions, stock repurchases and preferred dividend payments. In 1999, in connection with the acquisition of Biochrom, we increased our long-term indebtedness by approximately $5.5 million and issued approximately $1.0 million in convertible preferred stock. As a result, the level of debt service required increased substantially compared to historical levels. Upon completion of the offering, we intend to use a portion of the proceeds to redeem our series A redeemable preferred stock in the amount of $1.5 million, and to repay the bank term loan, the subordinated debt and the revolving credit facility. Based on our operating plans, we expect that proceeds from this offering, available cash, cash generated from operations, and cash available from our revolving credit facility will be sufficient to finance operations and capital expenditures for at least two years from the date of this prospectus. However, we may use a substantial portion of the proceeds from this offering to accelerate product development, expand our sales and marketing activities or consummate acquisitions, although we have no current plans in this regard. Therefore, we may need to raise additional capital, which may be dilutive to existing stockholders. The additional capital may not be available on acceptable terms or at all. Accordingly, there can be no assurance that we will be successful in raising additional capital. 26

IMPACT OF FOREIGN CURRENCIES We sell our products in many countries and a substantial portion of our sales, costs and expenses are denominated in foreign currencies, especially the United Kingdom pound sterling and the Euro. In the first nine months of 2000 and in 1999, the U.S. dollar strengthened against these currencies resulting in reduced consolidated revenue growth, as expressed in U.S. dollars. In addition, the currency fluctuations resulted in foreign currency losses of approximately $48,000 in 1999 and $456,000 in the first nine months of 2000. Historically, we have not hedged our foreign currency position. Currently, we attempt to manage foreign currency risk through the matching of assets and liabilities. However, as our sales expand internationally, we plan to evaluate our currency risks and we may enter into foreign exchange contracts from time to time to mitigate foreign currency exposure. BACKLOG Our order backlog was approximately $2.7 million as of September 30, 2000 and $2.1 million as of September 30, 1999. We include in backlog only those orders for which we have received valid purchase orders. Purchase orders may be cancelled at any time prior to shipment. Our backlog as of any particular date may not be representative of actual sales for any succeeding period. We expect to ship substantially all of the September 30, 2000 backlog by December 31, 2000. ACCOUNTING PRONOUNCEMENTS In June 1998, the Financial Accounting Standard Board issued Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS 133 establishes accounting and reporting standards requiring that every derivative instrument be recorded in the balance sheet as either an asset or liability measured at its fair value. SFAS 133, as amended by SFAS 137 and SFAS 138, is effective for years beginning after June 15, 2000. SFAS 133 will be adopted on January 1, 2001. We believe the adoption of this statement will not have a significant impact on our financial position, results of operations or cash flows. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Interest rate risk and foreign currency rate risk are the primary sources of market risk to our operations. As of September 30, 2000, we had aggregate variable rate long-term debt of $6.8 million and revolving credit facility debt of $3.2 million. A 10% change in interest rates would change the annual interest expense on our long-term debt by approximately $68,000 and on our revolving credit facility by approximately $32,000. 27

BUSINESS OVERVIEW We are a global provider of innovative, research enabling tools for drug discovery. We provide a broad array of tools designed to accelerate the speed and to reduce the cost at which our customers can introduce new drugs. Since our 1996 reorganization, we have focused on alleviating the protein purification and ADMET screening bottlenecks in drug discovery. To address these two critical bottlenecks in protein purification and ADMET screening, we recently introduced several new proprietary tools. For protein purification, these tools include specially treated pipette tips, spin columns and micro-dialyzers. For ADMET screening, these tools include NaviCyte diffusion chambers for drug absorption testing, 96 well equilibrium dialysis plates for drug distribution testing and ScanTox in vitro toxicology screening instruments. We also have an established product base in proteomics, which is the study of gene function through the analysis of protein interactions. This product base consists of DNA/RNA/protein calculators, life science spectrophotometers and amino acid analysis systems, as well as precision infusion pumps, organ testing systems and ventilators used in ADMET screening. OUR HISTORY Our business began in 1901 and has grown over the intervening years with the development and evolution of modern drug discovery tools. Our past inventions include the mechanical syringe pump in the 1950s for drug infusion and the microprocessor controlled syringe pump in the 1980s. In March 1996, a group of investors led by our current management team acquired a majority of the then existing business of our predecessor, Harvard Apparatus. Following this acquisition, we redirected our strategy to focus on high growth areas within drug discovery by acquiring innovative technologies through strategic acquisitions and licensing while continuing to grow our existing business through internal product development and marketing. We have completed five business acquisitions, including Biochrom, the licensing of key new technology for in vitro toxicology assays and drug absorption measurement chambers, the internal development of new product lines, including new generation syringe pumps and DNA/RNA/protein calculators and the mailing of expanded new catalogs. INDUSTRY OVERVIEW The life sciences research industry is undergoing fundamental change and growth resulting principally from the explosive growth in gene discovery and the demand for greater efficiency in the drug discovery process. Industry experts estimate that in 2000, the life sciences research industry will spend more than $50 billion on drug discovery research and development. The goal of drug discovery is to find compounds that will bind specifically to a given target without significantly affecting any other molecules in the body. Traditionally, chemists have laboriously synthesized new compounds with potential therapeutic activity one at a time or painstakingly isolated them from natural resources. Today, combinatorial chemistry techniques are used to greatly increase the supply and diversity of such compounds. Libraries of hundreds of thousands, or even millions, of compounds are now available for testing in biological assays against targets. Until recently, life sciences researchers had identified only a few hundred targets against which to test these compounds. Driven by large-scale DNA sequencing projects, such as the Human Genome Project, life sciences researchers expect to identify tens of thousands of new genes as they decipher the genomes of both humans and disease-causing organisms. When a gene, which is a segment of DNA, is expressed, a copy of the gene sequence is carried in messenger RNA, or mRNA, which is used to direct the manufacture of a protein. Although genes, DNA, mRNA and proteins are all targets for 28

drug discovery, proteins are by far the most common. Proteins are the molecular machines of the cell that are responsible for performing the majority of cellular functions. Once proteins are identified and validated as potential targets, they need to be screened against hundreds of thousands, if not millions, of compounds in a process known as primary screening. Drug discovery is a time-consuming and costly process. In the pre-genomics era, the compound development, primary screening and clinical trials stages were bottlenecks in this process. The successes of genomics, combinatorial chemistry and high throughput screening in recent years have alleviated the bottlenecks at the compound development and primary screening stages. However, these bottlenecks have been replaced by bottlenecks at the target validation, assay development and absorption, distribution, metabolism, elimination and toxicology, or ADMET, testing stages. The revolution in genomics is expected to increase the number of targets from 500 to 10,000, which will consequently greatly increase the need for protein purification and analysis. The increase in the number of compounds in libraries from tens of thousands to millions together with the increase in the number of targets is greatly increasing the number of leads requiring ADMET screening. THE DRUG DISCOVERY PROCESS The drug discovery process consists of several steps, which are illustrated below. The diagram that illustrates the drug discovery process is initially split into two parallel tracks which merge into a single track as the diagram moves to the right. The upper track of the diagram is titled "Compound Development" and includes an arrow titled "Compound Libraries." Below the arrow are the words "Combinatorial Chemistry." The lower track of the diagram is titled "Target Discovery" and includes two arrows. The first arrow is titled "Target Identification." Below this arrow is the word "Genomics." The next arrow to the right is titled "Target Validation." Below this arrow is the word "Proteomics." Following the "Compound Libraries" arrow on the upper track and the "Target Validation" arrow on the lower track, the two tracks of the diagram combine and include arrows to illustrate the remaining stages and key bottlenecks in the drug discovery process. The individual arrows from left to right include an arrow titled "Assay Development" followed by an arrow titled "High Throughput Screening." These two arrows in the diagram appear under the title "Primary Screening." To the right of the "High Throughput Screening" arrow is an arrow titled "Lead Optimization" followed by an arrow titled "ADMET Screening." These two arrows in the diagram appear under the title "Secondary Screening." To the right of the "ADMET Screening" arrow is an arrow titled "Clinical Trials," the final arrow in the process flow diagram. TARGET IDENTIFICATION involves isolating a particular molecule, typically a protein, and evaluating the role that it plays in the body to determine whether it might be a viable target for further investigation. Today, this activity is most often initiated by genomics studies, including DNA sequencing, RNA analysis and genetic mapping. TARGET VALIDATION involves demonstrating that affecting the function of a particular target has a positive effect on the course of a disease. Target validation employs a variety of methods including RNA analysis, protein analysis and cell biology. Target validation is a more time-consuming process than target identification. PRIMARY SCREENING involves the large-scale testing of collections of chemical compounds, known as compound libraries, against validated targets. These libraries are tested using high throughput assays. The goal is to find individual compounds that bind to and inhibit or activate a particular target, commonly referred to as a hit. An assay, in the context of screening compounds against a new target, refers to a test a researcher must develop for measuring whether particular compounds in a library interact with the target in a certain manner. An assay must be developed for each target to be screened. The major pharmaceutical companies are moving towards screening up to 100 targets annually with libraries of up to one million compounds each. SECONDARY SCREENING involves the refinement of hits into leads that can be used in clinical trials. This step consists of lead optimization and ADMET testing. Lead optimization involves conducting successive rounds of chemical alterations and biological tests to find compounds similar to the original compound identified in primary screening which have improved drug properties over the initial compound, particularly efficacy. ADMET testing involves the conducting of various tests on compounds 29

to ensure that they are safe and have good pharmacological properties such as high adsorption into the blood from the digestive tract and good distribution to the site of the target molecule in the body. This stage also involves the testing of compounds to determine therapeutic activity in animal models of disease and to ensure that the compounds can be manufactured with consistent quality. CLINICAL TRIALS involve the testing of pharmaceutical compounds in humans to demonstrate their safety and efficacy. Because clinical trials are by far the most expensive part of drug discovery, and undesirable ADMET properties are the most common reasons for failure, pharmaceutical and biotechnology companies can achieve substantial cost savings by identifying drug candidates with poor ADMET properties as early in the drug discovery process as possible. Drugs with successful clinical trials are almost always commercialized. PROTEOMICS Proteomics involves the large-scale purification, identification and analysis of proteins. Proteins are manufactured in the body's cells according to the code contained in DNA and are the molecular machines of the cell that are responsible for performing the majority of cellular functions. Proteins are the most common targets in the field of drug discovery because proteins tend to be far more accessible to drugs than either DNA or mRNA which are located in the nucleus of the cell. Every protein that is identified as a potential target must be analyzed. The trend in protein analysis currently is moving towards the use of mass spectrometry, which is the fastest and most accurate technique for protein analysis. Because mass spectrometers are highly sensitive, they require the use of pure samples in order to properly analyze the protein. Thus, protein purification, the removal of reagents such as salts, detergents and buffers, is essential to target discovery. In the last few years the revolution in genomics and the completion of the Human Genome Project has vastly increased the number of known targets. Before the Human Genome Project there were only approximately 500 known targets. Some experts believe that the sequencing of the human genome will ultimately lead to the identification of 50,000 to 100,000 genes and over 1,000,000 proteins. Many scientists expect that this will in turn lead to the identification of up to 10,000 targets. Each of these targets, many of which will be proteins, will need to be purified and analyzed many times prior to becoming a validated target for primary screening. As a result of the recent and projected increases in the number of known drug targets, purifying protein samples has been and will continue to be a significant bottleneck in the drug discovery process. ADMET SCREENING The goal of ADMET screening is to identify compounds that have toxic side effects or undesirable pharmacological properties. These compounds are then either eliminated or further chemically modified and re-screened. While ADMET screening is traditionally conducted late in the drug discovery process, early application of ADMET screening can be highly beneficial. This is because more than half of the 90% of lead compounds which fail in the costly clinical trial stage of drug discovery fail due to poor pharmacological properties. These important pharmacological properties consist of absorption, distribution, metabolism and elimination which, together with toxicology, are described below: ABSORPTION. Absorption describes the ability of a drug to pass through the wall of the digestive tract and enter the blood stream. Absorption is an important property of an effective drug because adequate absorption allows a drug to be administered orally rather than by direct injection into the blood. If a lead candidate cannot be absorbed easily from the digestive tract into the blood, its commercial viability will be adversely impacted even if it effectively acts against the target. 30

DISTRIBUTION. Distribution describes the amount of a drug that different tissues in the body take in from the blood. Distribution of the drug to the tissue containing the target molecule is necessary for the drug to have the desired effect. Moreover, undesirable side effects may occur if the drug is distributed to tissues other than the one containing the target molecule. Effective distribution requires the drug to be transported around the body and released into the tissue containing the target molecule at an appropriate rate. The flow of blood alone is often an effective distribution method. However, while the binding of a drug to blood proteins can increase the proper distribution of a drug, it can cause toxic problems if the bond formed is too strong. METABOLISM. Metabolism describes the chemical changes that the body makes to a drug. This is an important property of an effective drug for three reasons. First, some drugs must be metabolized in order to become effective. Second, some drugs may have no toxic side effects, but the byproducts of their metabolism, known as metabolites, may be toxic. Third, metabolism usually makes drugs more soluble in water, which in turn makes it easier for the body to eliminate them in the urine. ELIMINATION. Elimination describes the process by which the body expels a drug. If the blood absorbs a drug, it will be primarily eliminated in the urine either in its native or metabolized forms. Elimination is important because toxicity is primarily a matter of concentration--even common compounds such as aspirin and caffeine are toxic at high enough concentrations. If the body does not eliminate a drug, the drug's concentration will build up with every dose taken, eventually reaching toxic levels. TOXICOLOGY. Toxicology describes the adverse effects a drug has on the body. These range from nausea to death. All drugs must be shown to be safe to the satisfaction of regulatory authorities prior to commercialization. Toxicology consists of tests designed to determine the likelihood that a drug will cause death or the growth of tumors, disrupt normal reproductive function or the immune system or mutate DNA. For every 1,000 hits identified through primary screening, only about ten survive secondary screening and make it into clinical trials, the final stage of drug discovery. Of those ten, only one, on average, survives the regulatory process to be commercialized as a new drug. CURRENT TECHNOLOGIES FOR PROTEIN PURIFICATION AND ADMET SCREENING PROTEIN PURIFICATION. Protein purification is an essential step in proteomics. Researchers must remove any salts, buffers, detergents and cellular debris prior to analyzing a protein sample. Current technologies for protein purification include packed bed columns and dialysis. In order to isolate a specific protein, two-dimensional gel electrophoresis, or 2DGE, is typically used in advance of running a sample through a packed bed column or dialysis. Two-dimensional gel electrophoresis isolates different types of proteins in a two-stage process using electric currents passed through gels. Each protein migrates to a specific location in the gel. The protein can then be separated from the gel residue using packed bed columns or dialysis. PACKED BED COLUMNS are small disposable plastic tubes containing chromatography media. A protein sample is typically pipetted into the top of the column, which is then placed in a centrifuge or vacuum manifold to draw the sample through the media. These columns will remove salts, detergents, buffers and 2DGE gel residue, but may retain some of the protein in the media. DIALYSIS involves the use of a porous membrane which allows small molecules such as salts, detergents, buffers and 2DGE gel residue to pass through but blocks larger molecules such as proteins from passing through. Dialysis involves pipetting the protein sample into a device which consists of a chamber with the porous membrane covering one otherwise open end. The chamber is then placed in a large volume of pure water and stirred for a period of time, which may be minutes or hours. 31

ADMET SCREENING. ADMET testing at the secondary screening stage has traditionally relied almost exclusively on live animal testing instead of tools. The most common animals used in drug discovery studies are laboratory rats and mice. As a drug compound moves closer to human clinical trials, the United States Food and Drug Administration requires that studies be performed using larger animals, such as rabbits and dogs. LIMITATIONS OF CURRENT TECHNOLOGIES PROTEIN PURIFICATION. Current technologies for protein purification in proteomics have the following limitations: - LOW PRODUCTIVITY. Neither packed bed columns nor dialyzers are easily capable of automated sample handling. Using packed bed columns, either alone or in connection with two-dimensional gel electrophoresis, requires centrifugation or the use of a vacuum to move the sample through the purification media. This means the sample must be physically moved to the centrifuge or vacuum pump, left to run--typically for several minutes--then removed, washed and the protein eluted. - LOSS OF PROTEIN SAMPLE. Packed bed columns consume a portion of the sample leading to sample loss. The amount of sample lost in the purification process may only be microliters. This is not a significant problem if several milliliters of sample are available, as is common in DNA purification. However, if only a few microliters of sample are available, as is common in protein purification, the loss of even one microliter may be a large percentage of the total. In addition, protein samples are typically expensive and thus sample loss must be minimized. ADMET SCREENING. Current technologies for ADMET screening have the following limitations: - HIGH COST. Animal assays are costly because all animals have to be housed and cared for under strict government regulations often in clean room environments and with a significant staff to care for the animals. A standard 14-day range finding study performed using laboratory rats costs approximately $75,000, and a two-year carcinogenicity study carried out with laboratory rats costs approximately $1 million. A later stage 90-day study carried out using dogs typically costs almost twice as much as the same test performed using laboratory rats. - LABOR INTENSITY. By their nature, animal assays cannot be automated and thus require the time of highly skilled research scientists, such as surgeons and pathologists. - ETHICAL CONSIDERATIONS. Even though researchers must use the lowest number of the least sentient animals to achieve the scientifically needed information, avoid pain and consider alternatives to the use of live animals, the large number of animals used still creates ethical considerations. OUR SOLUTIONS We overcome the limitations of current technologies by providing innovative, enabling tools for protein purification and ADMET screening. PROTEIN PURIFICATION Our protein purification technologies are designed to be quick to use and to reduce sample loss. - HIGHER PRODUCTIVITY. Our purification pipette tips are quicker to use than packed bed columns because a centrifugation or vacuuming step is not necessary. This avoids both the moving of the sample to and from the centrifuge or vacuum pump and the run time in the centrifuge or vacuum pump. We believe our protein purification pipette tips are the only pipette tips capable of being fitted to standard pipetting workstations and thus being used for automated protein 32

purification. This automation increases our customers' productivity. In addition, our 96 well plate versions of dialyzers and spin columns can be used directly in automated equipment, again increasing our customers' productivity. - REDUCED SAMPLE LOSS. Our miniaturization of dialyzers and spin columns reduces sample loss in the membrane or column material. Our purification pipette tips contain smaller volumes of material than packed bed columns and thus less sample is retained in the material. ADMET SCREENING Our ADMET screening technologies employ novel approaches to obtaining ADMET data while reducing the use of large numbers of live animals. - LOWER COST. Most of our ADMET screening products use organs, tissue or blood proteins rather than live animals. For example, our in vitro toxicology assay uses the lenses of cows' eyes obtained as a by-product of the beef industry, and our 96 well plate for serum protein binding uses blood proteins in vitro rather than in the bloodstream of live laboratory animals. - IMPROVED AUTOMATION. Our in vitro toxicology assay can be run in a few minutes of instrument time and a few hours of elapsed time. By contrast, basic toxicology tests in animals typically take days of elapsed time and more advanced tests take weeks or months. Our 96 well plate for serum protein binding, for instance, can be run on automated liquid handling equipment. - REDUCED ANIMAL USAGE. Our in vitro toxicology assay uses cow eye lenses instead of live animals to detect toxic effects of compounds. Our drug absorption chamber uses cultured human colon cells instead of animal intestinal tissue to simulate the absorption of a drug into the blood from the digestive tract. Our 96 well plate for serum protein binding tests the binding ability of compounds on extracted blood proteins instead of infusing the compounds into the bloodstreams of live test animals. OUR STRATEGY Our goal is to become the leading provider of innovative, enabling technologies and products for proteomics and ADMET research in the drug discovery process. Key elements of our strategy are to: ESTABLISH OUR PROTEOMICS AND ADMET SCREENING PRODUCTS AS INDUSTRY STANDARDS In order to establish our products as industry standards, we intend to provide a broad selection of products focused on the target validation and ADMET screening stages of the drug discovery process. We have recently introduced several new innovative products designed to reduce the cost and time associated with protein purification and ADMET screening in drug discovery. We have already begun to realize revenue from the sales of our products, including purification pipette tips, spin columns, dialyzers, in vitro toxicology assays and equilibrium dialysis plates. We intend to rapidly increase the market acceptance of these products through the development of new uses for these products, focused, direct marketing campaigns to our extensive customer base and promotions at scientific exhibitions. LAUNCH A BROAD RANGE OF INNOVATIVE NEW TOOLS FOR DRUG DISCOVERY Since our reorganization in 1996, we have focused on becoming a leading provider of tools for proteomics and ADMET screening. We believe that our customers are eager to acquire new and innovative tools that reduce drug discovery time and expense. Since 1996, we have introduced several new tools for proteomics and ADMET screening such as our protein and DNA purification pipette tips, protein purification dialyzers, ScanTox in vitro toxicology assay and NaviCyte diffusion chambers. We intend to continue to identify, develop and introduce new tools to alleviate bottlenecks in all stages of the drug discovery process. 33

LEVERAGE OUR EXISTING DISTRIBUTION AND MARKETING CHANNELS We intend to leverage the strength of our existing distribution channels to launch new products. Our 1,000 page catalog is currently distributed worldwide to approximately 100,000 researchers engaged in drug discovery and is also accessible on our website. Our customer list consists primarily of research personnel, who are the end-users of our products and largely responsible for initiating the purchase of our products. We also have wholly-owned subsidiaries in the United Kingdom, Germany, France and Canada providing us with an international market presence. In addition, some of our products are sold through a distribution arrangement with Amersham Pharmacia Biotech, or APBiotech, providing us with access to APBiotech's extensive customer base, reputation and support infrastructure. We believe that our extensive existing distribution channels, when combined with our strong reputation for high quality, reliable and durable tools, provides us with a competitive advantage in bringing new products to market quickly and cost effectively. PROVIDE A SINGLE SOURCE OF TOOLS FOR OUR CUSTOMERS' RESEARCH NEEDS IN PROTEOMICS AND ADMET SCREENING We seek to provide our customers with all of the tools necessary to conduct a wide variety of proteomic and ADMET experiments that are crucial to the drug discovery process. We believe that being a single source sets us apart from our competitors by increasing the likelihood that our customers will turn to our catalog or website first when looking for help with a particular experiment. Currently, our catalog and website include approximately 10,000 products. In addition, our extensive product selection allows us to leverage the sales of our proprietary products through the simultaneous sale of complementary products. ACQUIRE COMPLEMENTARY TECHNOLOGIES We intend to selectively acquire companies and technologies which we believe will strengthen our portfolio of tools for drug discovery, particularly in the areas of proteomics and ADMET screening. Since 1996, we have completed the acquisition of Biochrom, four other acquisitions involving the integration of acquired products and technology into our existing manufacturing base and distribution channel, and three technology acquisition or licensing transactions. In the future, we may pursue acquisitions of new products and technologies through business acquisitions, partnerships or licensing arrangements. 34

This coating selectively binds proteins, but not the salts, detergents, electrophoresis gels, buffers and cellular debris that are often mixed in with the proteins. Our PrepTip pipette tip enables customers to rapidly purify proteins by avoiding the time-consuming usage of a centrifuge required when using spin columns. In addition, it is easy to use because the protein solution is handled entirely within the pipette tip and does not have to 35

be moved through a separate device like a packed bed column or dialyzer. Because our PrepTip pipette tips use the same chromatography media as packed bed columns, they can take advantage of the wide range of existing purification protocols using these media. PURETIP DNA PURIFICATION PIPETTE TIPS PureTip pipette tip uses a pipette tip that is similar to the PrepTip pipette tip, but is loaded with a gel rather than coated. This is well suited for performing DNA purification. PureTip pipette tips are more adaptable to automation than spin columns because they fit onto automated pipetting workstations. We expect to launch the PureTip pipette tip later this year. SPIN COLUMNS Spin columns are short plastic tubes that contain purification media. Once a sample is placed in the tube, it is typically spun in a centrifuge to move the sample through the media and separate the proteins from the other cellular debris. Our Ultra Micro spin columns, which we provide in both single and 96 well plate versions, contain chromatography media for use in purifying sample volumes as small as five microliters. This is significantly smaller than the sample volume required by columns produced by our largest competitors. PROTEIN PURIFICATION DIALYZERS Dialyzers are small chambers with an open end covered with a membrane. The membrane allows small molecules to pass through but not large molecules. Because proteins are large molecules and most contaminants are small molecules, this is an effective way to purify proteins. We make single- and double-sided reusable and disposable dialyzers. DISPOSABLE EQUILIBRIUM DIALYZERS Our proprietary disposable equilibrium dialyzers are effective cost-efficient products for protein binding studies and can handle sample sizes as small as 75 microliters. These disposable products are particularly useful for binding studies involving radioactively labeled compounds because the dialyzer does not require cleaning after use. PROTEOMICS PRODUCTS--PROTEIN ANALYSIS MOLECULAR BIOLOGY SPECTROPHOTOMETERS A spectrophotometer is an instrument widely used in molecular biology and cell biology to quantify the amount of a compound in a sample by shining a beam of white light through a prism or grating to divide it into component wavelengths. Each wavelength in turn is shone through a liquid sample and the spectrophotometer measures the amount of light absorbed at each wavelength. This enables the quantification of the amount of a compound in a sample. We sell a wide range of spectrophotometers under the names UltroSpec and NovaSpec. These products are manufactured by our Biochrom subsidiary and sold primarily through our distribution arrangement with Amersham Pharmacia Biotech. DNA/RNA/PROTEIN CALCULATORS A DNA/RNA/protein calculator is a bench top instrument dedicated to quantifying the amount of DNA, RNA or protein in a sample. It uses a process similar to that of a molecular biology spectrophotometer. These are sold under the names GeneQuant and GeneQuantPro. Launched in 1993, we believe that we were the first company to sell such an instrument. These products are manufactured by our Biochrom subsidiary and sold primarily through Amersham Pharmacia Biotech. MULTI-WELL PLATE READERS Multi-well plate readers are widely used for high throughput screening assays in the drug discovery process. The most common format is 96 wells. They use light to detect chemical interactions. We plan to introduce a range of these products beginning with absorbance readers in the fourth quarter of 2000 36

and luminescence and fluorescence readers in 2001 primarily for distribution through Amersham Pharmacia Biotech. AMINO ACID ANALYSIS SYSTEMS An amino acid analysis system uses chromatography to separate the amino acids in a sample and then uses a chemical reaction to detect each one in turn as they flow out of the chromatography column. Amino acids are the building blocks of proteins. In June 2000, we acquired substantially all of the amino acid analysis systems business of the Biotronik subsidiary of Eppendorf-Netheler-Hinz GmbH and integrated it with the existing amino acid analysis systems business in our Biochrom subsidiary. ADMET SCREENING PRODUCTS We have traditionally sold products for ADMET testing that are based upon animal models. However, as a result of a series of acquisitions and licensing transactions, we have begun to develop and manufacture organ testing systems, tissue testing systems and serum protein binding assays for early toxicology testing. NAVICYTE DIFFUSION CHAMBERS A diffusion chamber is a small plastic chamber with a membrane separating the two halves of the chamber used to measure the absorption of a drug into the bloodstream. The membrane can either be tissue such as intestinal tissue or a cultured layer of cells such as human colon cells. This creates a miniaturized model of intestinal absorption. We entered this market with our 1999 acquisition of the assets of NaviCyte Inc. a wholly owned subsidiary of Trega Biosciences. 96 WELL EQUILIBRIUM DIALYSIS PLATE FOR SERUM PROTEIN BINDING ASSAYS Our 96 well equilibrium dialysis plate operates in a similar way to the equilibrium dialyzers for target validation described above. The difference is that both chambers on either side of the membrane are capped. The protein target is placed on one side of the membrane and the drug on the other. The small molecule drug diffuses through the membrane. If it binds to the target, it cannot diffuse back again. If it does not bind, it will diffuse back and forth until an equilibrium is established. Thus, measuring the drug concentration determines the strength of binding. This product is principally used for ADMET screening to determine if a drug binds to blood proteins. A certain level of reversible binding is advantageous in order to promote good distribution of a drug through the human body. However, if the binding is too strong, it may impair normal protein function and cause toxic effects. ORGAN TESTING SYSTEMS Organ testing systems use glass or plastic chambers together with stimulators and recording electrodes to study organ function. Organ testing systems enable either whole organs or strips of tissue from organs such as hearts, livers and lungs to be kept functioning outside the body while researchers perform experiments with them. They are typically used in place of live animals. We have sold basic versions of these systems for many years, but have significantly expanded our product offerings through our November 1999 acquisition of Hugo Sachs Elektronik. Studies on isolated livers are useful in determining metabolism and studies on kidneys are useful in determining elimination. SCANTOX IN VITRO TOXICOLOGY SCREENING Our proprietary ScanTox in vitro toxicology screening system uses a living organ system, a bovine eye lens, to detect the toxic effect of compounds by measuring the refraction of laser light passing through the eye lens. A healthy lens focuses light to a point, but when a toxic compound is added to 37

the lens environment, the lens reacts by defocusing. The extent of defocusing is measured and analyzed by the instrument. Its advantages include: - higher relevance to whole body toxicology than a cell-based assay, without the complicated support and measurement apparatus needed for other organs such as hearts or lungs, - higher sensitivity and reproducibility than live animal assays, - higher sensitivity than other tissue assays, and - easier operation than other animal or tissue assays because the data is collected and analyzed automatically. PRECISION INFUSION PUMPS Infusion pumps, typically syringe pumps, are used to accurately infuse very small quantities of liquid, commonly drugs. Infusion pumps are typically used for long-term toxicology testing of drugs by infusion into animals, typically laboratory rats. We sell 80 types of syringe pumps. OTHER PRODUCTS CELL INJECTION SYSTEMS Cell injection systems use extremely fine bore glass capillaries to penetrate and inject drugs into or around individual cells. Cell injection systems are used to study the effects of drugs on single cells. Injection is accomplished either with air pressure or, if the drug molecule is electrically charged, by applying an electric current. We entered this market with our 1998 acquisition of the research products of Medical Systems Corporation. VENTILATORS Ventilators use a piston driven air pump to inflate the lungs of an anesthestised animal. Ventilators are typically used in surgical procedures common in drug discovery. Our advanced Inspira ventilators have significant safety and ease of use features, such as default safety settings, not found on other ventilators. CPK ATOMIC MODELS CPK atomic models use colored plastic parts to accurately model molecular structures, such as DNA. We offer a wide range of components and assembled models. STRONGHOLD LABORATORY CLAMPS Stronghold laboratory clamps are made from glass reinforced nylon. Our clamps resist rusting which is a common problem with steel clamps. We provide a wide variety of clamps, stands and lattices. OEM PRODUCTS Our reputation for quality, durability and reliability has led to the formation of a number of original equipment manufacturer, or OEM, relationships with major life science instrument companies. These relationships are conducted through purchase orders and are not contractual. A good example of these relationships is with respect to our syringe pumps. Our syringe pumps are capable of delivering flow rates as low as 0.001 microliters per hour while maintaining high accuracy. We have adapted, in conjunction with our OEMs, the core technology embodied in our syringe pumps to make specialized sample injectors for many of the major mass spectrometry manufacturers. 38

DISTRIBUTED PRODUCTS In addition to the manufactured products described above, we buy and resell through our catalog products made by other manufacturers. We have negotiated supply agreements with the majority of the companies that provide our distributed products. These supply agreements specify pricing only and contain no minimum purchase commitments. None of these agreements represents more than two percent of our revenues. Distributed products accounted for approximately 18% of our revenues for the nine months ended September 30, 2000. These distributed products enable us to provide our customers with a single source for their experimental needs. These complementary products consist of a large variety of devices, instruments and consumable items used in experiments involving animals and biological tissue in the fields of proteomics, physiology, pharmacology, neuroscience, cell biology, molecular biology and toxicology. Our manufactured products are often leaders in their fields, but researchers often need complementary products in order to conduct their particular experiments. Most of these complementary products come from small companies without our extensive distribution and marketing channel. OUR CUSTOMERS Our customers are primarily end user research scientists at pharmaceutical and biotechnology companies, universities and government laboratories, such as the U.S. National Institutes of Health, or NIH. Our largest customers in the United States include Baylor College of Medicine, Bristol-Myers Squibb Company, Eli Lilly and Company, Johns Hopkins University, Merck & Co., Inc., NIH, Parke- Davis, Pfizer Inc., Schering-Plough Corporation, SmithKline Beecham plc and the University of California. We conduct direct sales in the United States, the United Kingdom, Germany, France and Canada. We also maintain distributors in other countries. Aggregate sales to our largest customer, Amersham Pharmacia Biotech, as a distributor with end users similar to ours, accounted for approximately 39% of our revenue for the nine months ended September 30, 2000, and 44% of our revenue for the fiscal year ended December 31, 1999. We have several thousand customers worldwide and no other customer accounted for more than five percent of our revenue for such periods. SALES AND MARKETING DIRECT SALES We periodically produce and mail approximately 100,000 copies of our 1,000-page catalog, which contains approximately 10,000 items. We distribute the majority of our products ordered from our catalog through our worldwide subsidiaries. Our manufactured products accounted for approximately 82% of our revenues for the nine months ended September 30, 2000. The complete catalog is also available as a CD-ROM and can be accessed on our website, www.harvardbioscience.com. Our significant positions in many of our manufactured products create traffic to the catalog and web site which enables cross-selling and facilitates the introduction of new products. In addition to the comprehensive catalog, we create and mail abridged catalogs which focus on specific product areas along with direct mailers which introduce or promote new products. AMERSHAM PHARMACIA BIOTECH DISTRIBUTOR Since the 1970s, our Biochrom subsidiary has used Amersham Pharmacia Biotech, or APBiotech, and its predecessors as its primary marketing and distribution channel. When we acquired Biochrom from Pharmacia and Upjohn in 1999, we signed a distribution, marketing and new product development agreement with APBiotech. Under the terms of this agreement, APBiotech serves as the exclusive distributor, marketer and seller of a majority of the products of our Biochrom subsidiary. During the term of this agreement, APBiotech has agreed to purchase a minimum number of our products for an 39

annual amount of $12.5 million, subject to adjustment for price increases and product sales volume. We have certain affirmative duties under the agreement to assist APBiotech in the sale of our products. For example, we have agreed to cooperate with APBiotech in its sales and marketing program and to provide sales, demonstration and support training for APBiotech. This agreement may be terminated early under specified circumstances. For example, if we breach the exclusivity, pricing or shipping provisions of the agreement and fail to remedy the breach within 30 days of receiving written notice of the breach from APBiotech, then the agreement may be terminated. In addition, we may terminate the agreement under specified circumstances. For example, failure by APBiotech to place certain information in escrow, to pay for products or to purchase a minimum number of products each year enables us to terminate the agreement unless APBiotech remedies the breach within 30 days of receiving written notice of the breach from us. This agreement may be terminated by either party upon 18 months' prior written notice. This agreement does not have a finite term, but remains in effect until terminated by either us or APBiotech. RESEARCH AND DEVELOPMENT Our principal research and development mission is to develop a broad portfolio of technologies, products and core competencies in drug discovery tools, particularly for application in the areas of proteomics and ADMET. Our development expenditures were $206,000 in 1997, $325,000 in 1998 and $1.2 million in 1999. We anticipate that we will continue to make significant development expenditures. We plan to continue to pursue a balanced development portfolio strategy of originating new products from internal research and development programs and business and technology acquisitions. We maintain development staff in each of our manufacturing facilities to design and develop new products. In-house development is focused on our current technologies. For new technologies, our strategy has been to license or acquire proven technology from universities and biotechnology companies and then develop the technology into commercially viable products. MANUFACTURING We manufacture and test the majority of our products in our four principal manufacturing facilities located in the United States, the United Kingdom and Germany. We have considerable manufacturing flexibility at our various facilities, and each facility can manufacture multiple products at the same time. We maintain in-house key manufacturing know-how, technologies and resources. We seek to maintain multiple suppliers for key components that are not manufactured in-house. Our manufacturing operations are essentially to assemble and test. Our manufacturing of syringe pumps, ventilators, cell injectors and protein purification products takes place in Holliston, Massachusetts. Our manufacturing of spectrophotometers and amino acid analysis systems takes place in Cambridge, England. Our manufacturing of surgery-related products and teaching products takes place in Edenbridge, England. Our manufacturing of complete organ testing systems takes place in March-Hugstetten, Germany. Our Cambridge, England facility is certified to ISO 9001. COMPETITION The markets into which we sell our products are highly competitive, and we expect the intensity of competition to increase. We compete with many companies engaged in developing and selling tools for drug discovery. Many of our competitors have greater financial, operational, sales and marketing resources, and more experience in research and development and commercialization than we have. Moreover, competitors may have greater name recognition than we do, and many offer discounts as a competitive tactic. These competitors and other companies may have developed or could in the future develop new technologies that compete with our products or which could render our products obsolete. 40

We cannot assure you that we will be able to make the enhancements to our technologies necessary to compete successfully with newly emerging technologies. We are not aware of any significant products sold by us which are currently obsolete. We believe that we offer one of the broadest selections of protein purification and ADMET technologies to companies engaged in drug discovery. We are not aware of any competitor which offers a product line of comparable breadth within the protein purification and ADMET product markets. We have numerous competitors on a product line basis. We believe that we compete favorably with our competitors on the basis of product performance, including quality, reliability and speed, technical support, price and delivery time. We compete with several companies that provide instruments for proteomics and ADMET screening. In the DNA/RNA/protein calculator area, we compete with PerkinElmer Instruments, Inc. and Bio-Rad Laboratories, Inc. In the molecular biology spectrophotometer area, we compete with Beckman Coulter, Inc. and PerkinElmer Instruments, Inc. In the protein sample preparation area, we compete with Millipore Corporation, Pierce Chemical Company and Spectrum Medical. In the ADMET screening area, we compete with KD Scientific, Razel Scientific Instruments, Inc., Experimetria Ltd., Kent Scientific Corporation, Warner Instruments, General Valve Company, Eppendorf-Netheler-Hinz GmbH, Ugo Basile and Becton, Dickinson and Company. In the area of OEM products, we face competition primarily from the in-house engineering teams of our OEM customers. INTELLECTUAL PROPERTY To establish and protect our proprietary technologies and products, we rely on a combination of patent, copyright, trademark and trade-secret laws, as well as confidentiality provisions in our contracts. Most of our new technology is covered by patents or patent applications. Most of our base business is protected by trade names and trade secrets only. We have implemented a patent strategy designed to provide us with freedom to operate and facilitate commercialization of our current and future products. We currently own ten issued U.S. patents and have four pending applications. We also hold exclusive licenses for the technologies used in our ScanTox in vitro toxicology products, our NaviCyte drug absorption products and our PureTip pipette tip products. In addition to these licenses, our principal technologies are covered by issued patents for our dialyzers and our Ultra Micro spin columns and by pending applications for our PrepTip pipette tips. Furthermore, international patent applications are pending in connection with one of our U.S. patent applications and one of our licensed patents. Generally, U.S. patents have a term of 17 years from the date of issue for patents issued from applications filed with the U.S. Patent Office prior to June 8, 1995, and 20 years from the application filing date or earlier claimed priority date in the case of patents issued from applications filed on or after June 8, 1995. Our issued US patents will expire between 2011 and 2018. Our success depends to a significant degree upon our ability to develop proprietary products and technologies. We intend to continue to file patent applications as we develop new products and technologies. Patents provide some degree of protection for our intellectual property. However, the assertion of patent protection involves complex legal and factual determinations and is therefore uncertain. The scope of any of our issued patents may not be sufficiently broad to offer meaningful protection. In addition, our issued patents or patents licensed to us may be successfully challenged, invalidated, circumvented or unenforceable so that our patent rights would not create an effective competitive barrier. Moreover, the laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States. In addition, the laws governing patentability and the scope of patent coverage continue to evolve, particularly in areas of interest to us. As a result, there can be no assurance that patents will issue from any of our patent applications or from applications 41

licensed to us. In view of these factors, our intellectual property positions bear some degree of uncertainty. We also rely in part on trade-secret protection of our intellectual property. We attempt to protect our trade secrets by entering into confidentiality agreements with third parties, employees and consultants. Our employees and consultants also sign agreements requiring that they assign to us their interests in patents and copyrights arising from their work for us. Many of our U.S. employees have signed agreements not to compete unfairly with us during their employment and after termination of their employment, through the misuse of confidential information, soliciting employees, soliciting customers and the like. However, it is possible that these agreements may be breached or invalidated and if so, there may not be an adequate corrective remedy available. Despite the measures we have taken to protect our intellectual property, we cannot assure you that third parties will not independently discover or invent competing technologies, or reverse engineer our trade secrets or other technologies. Therefore, the measures we are taking to protect our proprietary rights may not be adequate. We do not believe that our products infringe on the intellectual property rights of any third party. We cannot assure you, however, that third parties will not claim such infringement by us or our licensors with respect to current or future products. We expect that product developers in our market will increasingly be subject to such claims as the number of products and competitors in our market segment grows and the product functionality in different market segments overlaps. In addition, patents on production and business methods are becoming more common and we expect that more patents will issue in our technical field. Any such claims, with or without merit, could be time-consuming, result in costly litigation and diversion of management's attention and resources, cause product shipment delays or require us to enter into royalty or licensing agreements. Moreover, such royalty or licensing agreements, if required, may not be on terms acceptable to us, or at all, which could seriously harm our business or financial condition. GOVERNMENT REGULATION We are not subject to direct governmental regulation other than the laws and regulations generally applicable to businesses in the domestic and foreign jurisdictions in which we operate. In particular, we are not subject to regulatory approval by the United States Food and Drug Administration as none of our products are sold for use in diagnostic procedures or on human clinical patients. In addition, we believe we are in compliance with all relevant environmental laws. EMPLOYEES As of October 15, 2000, we had 127 full-time employees and 6 part-time employees, 38 of whom resided in the United States, 77 of whom resided in the United Kingdom, 11 of whom resided in Germany, 3 of whom resided in France and 4 of whom resided in Canada. None of our employees is subject to any collective bargaining agreement. We believe that our relationship with our employees is good. FACILITIES Our four principal facilities incorporate manufacturing, development, sales and marketing and administration functions. Our facilities consist of: - a leased 20,000 square foot facility in Holliston, Massachusetts, which is our corporate headquarters, - a leased 28,000 square foot facility in Cambridge, England, - an owned 15,500 square foot facility in Edenbridge, England, and 42

- a leased 9,000 square foot facility in March-Hugstetten, Germany. We lease additional facilities for sales and administrative support in Les Ulix, Paris France and Montreal, Quebec Canada. LEGAL PROCEEDINGS On November 7, 2000, we received correspondence from counsel to Harvard University claiming that our use of the term "Harvard Bioscience" and other terms containing or consisting of the term "Harvard" constitutes trademark infringement, false designation of origin, unfair competition and cybersquatting. Counsel to Harvard University has also threatened us with legal action if we do not cease and permanently refrain from using these terms. We do not currently intend to take such steps, and we believe it is likely that Harvard University will pursue this matter against us. We believe that these claims are without merit, and we will vigorously seek to protect our rights regarding such claims. While we are still investigating the matter, we do not believe that the matter will have a material adverse effect on our business, financial position or results of operations. From time to time, we may be involved in various other claims and legal proceedings arising in the ordinary course of business. We are not currently a party to any other claims or proceedings which, we believe, if decided adversely to us, would either individually or in the aggregate have a material adverse effect on our business, financial condition or results of operations. 43

The following table sets forth the potential realizable value of the options granted to the listed executive officers using our assumed initial public offering price of $12.00 per share: POTENTIAL REALIZABLE VALUE AT ASSUMED ANNUAL RATES OF STOCK PRICE NUMBER OF APPRECIATION SECURITIES FOR OPTION TERM UNDERLYING ------------------------ OPTIONS GRANTED 5% 10% --------------- ---------- ----------- Chane Graziano........................................ 458,257 $8,478,047 $13,783,827 David Green........................................... 458,257 $8,478,047 $13,783,827 The potential realizable value is not intended to predict future appreciation of the price of our common stock. The values shown do not consider non-transferability, vesting or termination of the options upon termination of the employee's employment relationship with us. FISCAL YEAR-END OPTION VALUES The following table sets forth information concerning the number and value of unexercised options to purchase common stock held as of December 31, 1999 by the executive officers listed in the Summary Compensation Table. There was no public trading market for our common stock as of December 31, 1999. Accordingly, the values of the unexercised in-the-money options have been calculated on the basis of the estimated fair value of our common stock at December 31, 1999 of $3.67, less the applicable exercise price multiplied by the number of shares which may be acquired on exercise. None of the executive officers listed in the Summary Compensation Table exercised any stock options in fiscal 1999.

Our board of directors has adopted the 2000 Stock Option and Incentive Plan, subject to stockholder approval. The 2000 Stock Option and Incentive Plan will be submitted to our stockholders for approval in November 2000. The 2000 Stock Option and Incentive Plan allows for the issuance of up to 3,750,000 shares of common stock plus an additional amount equal to 15% of any net increase in the total number of shares of common stock outstanding after this offering. Our compensation committee will administer the 2000 Stock Option and Incentive Plan. Under the 2000 Stock Option and Incentive Plan, our compensation committee may: - grant incentive stock options, - grant non-qualified stock options, - grant stock appreciation rights, - issue or sell common stock with vesting or other restrictions, or without restrictions, 48

- grant rights to receive common stock in the future with or without vesting, - grant common stock upon the attainment of specified performance goals, and - grant dividend rights in respect of common stock. These grants and issuances may be made to our officers, employees, directors, consultants, advisors and other key persons. Our compensation committee has the right, in its discretion, to select the individuals eligible to receive awards, determine the terms and conditions of the awards granted, accelerate the vesting schedule of any award and generally administer and interpret the plan. The exercise price of options granted under the 2000 Stock Option and Incentive Plan is determined by our compensation committee. Under present law, incentive stock options and options intended to qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986 may not be granted at an exercise price less than the fair market value of the common stock on the date of grant, or less than 110% of the fair market value in the case of incentive stock options granted to optionees holding more than 10% of the voting power. Non-qualified stock options may be granted at prices which are less than the fair market value of the underlying shares on the date granted. Options are typically subject to vesting schedules, terminate 10 years from the date of grant and may be exercised for specified periods after the termination of the optionee's employment or other service relationship with us. Upon the exercise of options, the option exercise price must be paid in full either in cash or by certified or bank check or other instrument acceptable to the committee or, in the sole discretion of the committee, by delivery of shares of common stock that have been owned by the optionee free of restrictions for at least six months. The 2000 Stock Option and Incentive Plan and all awards issued under the plan will terminate upon a merger, reorganization or consolidation, the sale of all or substantially all of our assets or all of our outstanding capital stock or a liquidation or other similar transaction, unless Harvard Bioscience and the other parties to such transactions have agreed otherwise. All participants under the 2000 Stock Option and Incentive Plan will be permitted to exercise for a period of 30 days before any such termination all awards held by them which are then exercisable or will become exercisable upon the closing of the transaction. EMPLOYEE STOCK PURCHASE PLAN. The Employee Stock Purchase Plan was adopted by our board of directors in October 2000 subject to stockholder approval. The Employee Stock Purchase Plan will be submitted to stockholders in November 2000. Up to 500,000 shares of our common stock may be issued under the Employee Stock Purchase Plan. The Employee Stock Purchase Plan is administered by our compensation committee. The first offering under the Employee Stock Purchase Plan will commence on January 1, 2001 and end on June 30, 2001. Subsequent offerings will commence on each January 1 and July 1 thereafter and will have a duration of six months. Generally, all employees who are customarily employed for more than 20 hours per week as of the first day of the applicable offering period are eligible to participate in the Employee Stock Purchase Plan. Any employee who owns or is deemed to own shares of stock representing in excess of 5% of the combined voting power of all classes of our stock may not participate in the Employee Stock Purchase Plan. During each offering, an employee may purchase shares under the Employee Stock Purchase Plan by authorizing payroll deductions of up to 10% of his cash compensation during the offering period. Unless the employee has previously withdrawn from the offering, his accumulated payroll deductions will be used to purchase shares of our common stock on the last business day of the period at a price equal to 85% of the fair market value of our common stock on the first or last day of the offering period, whichever is lower. Under applicable tax rules, an employee may purchase no more than 49

$25,000 worth of our common stock in any calendar year under the Employee Stock Purchase Plan. We have not issued any shares to date under the Employee Stock Purchase Plan. 1996 STOCK OPTION AND GRANT PLAN. Our 1996 Stock Option and Grant Plan was initially approved by our board of directors and was approved by our stockholders in March 1996. Our 1996 Stock Option and Grant Plan provides for the issuance of 4,072,480 shares of our common stock. As of October 15, 2000, options to purchase 599,096 shares of our common stock were outstanding under our 1996 Stock Option and Grant Plan. Options granted under our 1996 Stock Option and Grant Plan generally vest over four years and terminate on the tenth anniversary of the date of grant. We will not make any additional grants under our 1996 Stock Option and Grant Plan after the completion of this offering. EMPLOYMENT ARRANGEMENTS We anticipate entering into employment agreements with each of Messrs. Graziano, Green and Warren. Each proposed agreement is for a period of two years, other than Mr. Warren's agreement which is for one year. Messrs. Graziano and Green's agreement automatically extends for two additional years on the second anniversary date and Mr. Warren's agreement automatically extends for one additional year on the anniversary date unless either party has given notice that it does not wish to extend the agreement. Each agreement provides for the payment of base salary and incentive compensation and for the provision of certain fringe benefits to the executive. Under their respective employment agreements, the annual salary for Mr. Graziano is $275,000, the annual salary for Mr. Green is $225,000 and the annual salary for Mr. Warren is $185,000. The agreements require our executive officers to refrain from competing with us and from soliciting our employees for a period of 12 months following termination for any reason. Each agreement also provides for certain payments and benefits for an executive officer should his or her employment with us be terminated because of death or disability, by the executive for good reason or by us without cause, as further defined in the agreements. In general, in the case of a termination by the executive officer for good reason, or by us without cause, the executive officer will receive up to two years' salary and bonus in the cases of Messrs. Graziano and Green and one years' salary and bonus in the case of Mr. Warren, an extension of benefits for one year and an acceleration of vesting for stock options and restricted stock which otherwise would vest during the next twenty-four months. Upon a change of control, as defined in the agreements, the executive officer is eligible for payment of up to three years' salary and bonus in the cases of Messrs. Graziano and Green and one-and-a-half years' salary and bonus in the case of Mr. Warren, an extension of benefits for one year and an acceleration of vesting for all outstanding stock options and restricted stock. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION Messrs. Dick and Klaffky are the members of our compensation committee. Neither Mr. Dick nor Mr. Klaffky is an executive officer of our company or has received any compensation from us within the last three years other than in his capacity as a director. 50

RELATIONSHIPS AND RELATED PARTY TRANSACTIONS STOCK REDEMPTIONS AND LOAN REPAYMENTS WITH STOCKHOLDERS In March 1996, our business was acquired by a group that was led by our current management team of Chane Graziano, our Chief Executive Officer, and David Green, our President, and that also included Paul Grindle, a former member of our board of directors, Ascent Venture Partners, L.P. (formerly known as Pioneer Venture Limited Partnership), Ascent Venture Partners II, L.P. (formerly known as Pioneer Venture Limited Partnership II) and First New England Capital, L.P. In connection with this acquisition, we issued redeemable preferred stock for an aggregate purchase price of $1.5 million and subordinated debentures with an aggregate principal amount of $1.0 million to our investors. The redeemable preferred stock pays cumulative dividends at the rate of $0.26 per share quarterly in arrears and the subordinated debentures bear interest at an annual rate of 13% payable quarterly in arrears. The terms of the redeemable preferred stock and the subordinated debentures require us to redeem or repay these instruments upon the completion of this offering. A portion of the proceeds of this offering will be used to retire the redeemable preferred stock and the subordinated debentures. The redemption of the preferred stock and the retirement of the subordinated debentures will result in payments of approximately $167,000 to Mr. Graziano, our Chief Executive Officer and a member of our board of directors, $500,000 to Ascent Venture Partners, L.P., $1.0 million to Ascent Venture Partners II, L.P. and $500,000 to First New England Capital, L.P. Christopher W. Dick, a member of our board of directors, is a Managing Director of Ascent Venture Management, Inc., the general partner of Ascent Venture Partners, L.P., and Ascent Management SBIC Corp., the general partner of Ascent Venture Partners II, L.P., and Richard C. Klaffky, Jr., a member of our board of directors, is the President of FINEC Corp., the general partner of First New England Capital, L.P. TRANSACTIONS WITH AN AFFILIATE OF AN EXECUTIVE OFFICER In March 1996, we acquired our business from a company now known as Harvard Clinical Technology Inc. Following this acquisition, we entered into several transition-related transactions with Harvard Clinical. In 1997, we sold Harvard Clinical several items of furniture, fixtures, appliances and equipment, leased Harvard Clinical office space on the same terms as the underlying lease with the third-party landlord, provided transition support services and assumed Harvard Clinical's obligations to pay $10,000 in professional fees in exchange for 1,529,180 shares of our common stock held by a principal stockholder of Harvard Clinical at an agreed upon value of $0.11 per share. The assets purchased by Harvard Clinical had an aggregate purchase price of approximately $93,000, which reflected their estimated fair market value as determined by Mr. Graziano, our Chief Executive Officer, and the value at which they were recorded on our balance sheet. We originally purchased these assets as part of the March 1996 acquisition of our business. We believe that each of these transactions was consummated on terms at least as favorable to us as could have been obtained from unaffiliated parties. Diane Green, who is an officer, director and stockholder of Harvard Clinical, is the spouse of Mr. Green, our President and a member of our board of directors. LOANS TO OFFICERS IN CONNECTION WITH OPTION EXERCISES In October 2000, Mr. Graziano, our Chief Executive Officer, and Mr. Green, our President, each exercised options to purchase 740,228 shares of our common stock. Each of these officers paid substantially all of the exercise price for these shares by issuing promissory notes to the Company. The aggregate loans to Mr. Graziano are $789,000 and to Mr. Green are $789,000 pursuant to these promissory notes. Each of these promissory notes is due in October 2003 and bears interest at an annual rate of 10%. These promissory notes are secured by a pledge of all of the shares for which the exercise price was paid with the respective promissory notes as well as additional shares held by each of these officers. 51

DESCRIPTION OF CAPITAL STOCK Following this offering, our authorized capital stock will consist of 80,000,000 shares of common stock and 5,000,000 shares of undesignated preferred stock, issuable in one or more series designated by our board of directors. No other class of capital stock will be authorized. Prior to this offering, our common stock was held by seven stockholders of record. The following information relates only to our certificate of incorporation and by-laws, as they will exist after this offering. COMMON STOCK VOTING RIGHTS. The holders of our common stock have one vote per share. Holders of our common stock are not entitled to vote cumulatively for the election of directors. Generally, all matters to be voted on by stockholders must be approved by a majority, or, in the case of election of directors, by a plurality, of the votes cast at a meeting at which a quorum is present, voting together as a single class, subject to any voting rights granted to holders of any then outstanding preferred stock. DIVIDENDS. Holders of common stock will share ratably in any dividends declared by our board of directors, subject to the preferential rights of any preferred stock then outstanding. Dividends consisting of shares of common stock may be paid to holders of shares of common stock. OTHER RIGHTS. Upon our liquidation, dissolution or winding up, all holders of common stock are entitled to share ratably in any assets available for distribution to holders of shares of common stock. No shares of common stock are subject to redemption or have preemptive rights to purchase additional shares of common stock. PREFERRED STOCK Our certificate of incorporation provides that 5,000,000 shares of preferred stock may be issued from time to time in one or more series. Our board of directors is authorized to fix the voting rights, if any, designations, powers, preferences, qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our board of directors may, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of the common stock and could have anti-takeover effects, including preferred stock or rights to acquire preferred stock in connection with implementing a shareholder rights plan. We have no present plans to issue any shares of preferred stock. The ability of our board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control with respect to our company or the removal of existing management. WARRANTS As of October 15, 2000, we had outstanding warrants to purchase 8,509,905 shares of common stock at an exercise price of $0.0005 per share. The warrants will expire on March 15, 2003. These warrants will be exercised in connection with this offering. REGISTRATION RIGHTS Following this offering, the holders of 17,208,101 shares of our common stock will have rights with respect to registration of these shares under the Securities Act of 1933. These rights are provided under the terms of a securityholders agreement between us and certain of the holders of registrable securities. Under these registration rights, holders of registrable securities holding 30% or more of the then outstanding registrable securities held by all holders of registrable securities may require on two occasions that we register their shares for public resale. In addition, certain holders of registrable securities may require that we register their shares for public resale on Form S-3 or similar short-form registration, if we are eligible to use Form S-3 or similar short form registration and the value of the 54

securities to be registered is at least $2,000,000. If we elect to register any of our shares of common stock for any public offering, the holders of registrable securities are entitled to include shares of common stock in the registration. However, we may reduce the number of shares proposed to be registered in view of market conditions. We will pay all expenses in connection with any registration, other than underwriting discounts and commissions. INDEMNIFICATION MATTERS Prior to the offering, we will have entered into indemnification agreements with each of our directors. The form of indemnification agreement provides that we will indemnify our directors for expenses incurred because of their status as a director to the fullest extent permitted by Delaware law, our certificate of incorporation and our by-laws. Our certificate of incorporation contains a provision permitted by Delaware law that generally eliminates the personal liability of directors for monetary damages for breaches of their fiduciary duty, including breaches involving negligence or gross negligence in business combinations, unless the director has breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or a knowing violation of law, paid a dividend or approved a stock repurchase in violation of the Delaware General Corporation Law or obtained an improper personal benefit. This provision does not alter a director's liability under the federal securities laws and does not affect the availability of equitable remedies, such as an injunction or rescission, for breach of fiduciary duty. Our by-laws provide that directors and officers shall be, and in the discretion of our board of directors, non-officer employees may be, indemnified by us to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended, against all expenses and liabilities reasonably incurred in connection with service for or on behalf of us. Our by-laws also provide for the advancement of expenses to directors and, in the discretion of our board of directors, to officers and non-officer employees. In addition, our by-laws provide that the right of directors and officers to indemnification shall be a contract right and shall not be exclusive of any other right now possessed or hereafter acquired under any by-law, agreement, vote of stockholders or otherwise. We also have directors' and officers' insurance against certain liabilities. We believe that the indemnification agreements, together with the limitation of liability and indemnification provisions of our certificate of incorporation and by-laws and directors' and officers' insurance will assist us in attracting and retaining qualified individuals to serve as our directors and officers. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be provided to directors, officers or persons controlling us as described above, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. At present, there is no pending material litigation or proceeding involving any of our directors, officers, employees or agents in which indemnification will be required or permitted. PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND BY-LAWS THAT MAY HAVE ANTI-TAKEOVER EFFECTS Certain provisions of our certificate of incorporation and by-laws described below, as well as the ability of our board of directors to issue shares of preferred stock and to set the voting rights, preferences and other terms thereof, may be deemed to have an anti-takeover effect and may discourage takeover attempts not first approved by our board of directors, including takeovers which particular stockholders may deem to be in their best interests. These provisions also could have the effect of discouraging open market purchases of our common stock because they may be considered disadvantageous by a stockholder who desires subsequent to such purchases to participate in a business combination transaction with us or to elect a new director to our board. 55

NO STOCKHOLDER ACTION BY WRITTEN CONSENT Our certificate of incorporation provides that any action required or permitted to be taken by our stockholders at an annual or special meeting of stockholders must be effected at a duly called meeting and may not be taken or effected by a written consent of stockholders. SPECIAL MEETINGS OF STOCKHOLDERS Our certificate of incorporation and by-laws provide that a special meeting of stockholders may be called only by our board of directors. Our by-laws provide that only those matters included in the notice of the special meeting may be considered or acted upon at that special meeting unless otherwise provided by law. ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND STOCKHOLDER PROPOSALS Our by-laws include advance notice and informational requirements and time limitations on any director nomination or any new proposal which a stockholder wishes to make at an annual meeting of stockholders. For the first annual meeting following the completion of this offering, a stockholder's notice of a director nomination or proposal will be timely if delivered to our secretary at our principal executive offices not later than the close of business on the later of the 75th day prior to the scheduled date of such annual meeting or the 10th day following the day on which public announcement of the date of such annual meeting is made by us. AMENDMENT OF THE CERTIFICATE OF INCORPORATION As required by Delaware law, any amendment to our certificate of incorporation must first be approved by a majority of our board of directors and, if required by law, thereafter approved by a majority of the outstanding shares entitled to vote with respect to such amendment, except that any amendment to the provisions relating to stockholder action by written consent, directors, limitation of liability and the amendment of our certificate of incorporation must be approved by not less than 75% of the outstanding shares entitled to vote with respect to such amendment. AMENDMENT OF BY-LAWS Our certificate of incorporation and by-laws provide that our by-laws may be amended or repealed by our board of directors or by the stockholders. Such action by the board of directors requires the affirmative vote of a majority of the directors then in office. Such action by the stockholders requires the affirmative vote of at least 75% of the shares present in person or represented by proxy at an annual meeting of stockholders or a special meeting called for such purpose unless our board of directors recommends that the stockholders approve such amendment or repeal at such meeting, in which case such amendment or repeal only requires the affirmative vote of a majority of the shares present in person or represented by proxy at the meeting. STATUTORY BUSINESS COMBINATION PROVISION Following the offering, we will be subject to Section 203 of the Delaware General Corporation Law, which prohibits a publicly-held Delaware corporation from consummating a "business combination," except under certain circumstances, with an "interested stockholder" for a period of three years after the date such person became an "interested stockholder" unless: - before such person became an interested stockholder, the board of directors of the corporation approved the transaction in which the interested stockholder became an interested stockholder or approved the business combination; 56

- upon the closing of the transaction that resulted in the interested stockholder becoming such, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding shares held by directors who are also officers of the corporation and shares held by employee stock plans; or - following the transaction in which such person became an interested stockholder, the business combination is approved by the board of directors of the corporation and authorized at a meeting of stockholders by the affirmative vote of the holders of at least two-thirds of the outstanding voting stock of the corporation not owned by the interested stockholder. The term "interested stockholder" generally is defined as a person who, together with affiliates and associates, owns, or, within the prior three years, owned, 15% or more of a corporation's outstanding voting stock. The term "business combination" includes mergers, consolidations, asset sales involving 10% or more of a corporation's assets and other similar transactions resulting in a financial benefit to an interested stockholder. Section 203 makes it more difficult for an "interested stockholder" to effect various business combinations with a corporation for a three-year period. A Delaware corporation may "opt out" of Section 203 with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or by-laws resulting from an amendment approved by holders of at least a majority of the outstanding voting stock. Neither our certificate of incorporation nor our by-laws contain any such exclusion. TRADING ON THE NASDAQ NATIONAL MARKET SYSTEM We have applied to have our common stock approved for quotation on the Nasdaq National Market under the symbol "HBIO." NO PREEMPTIVE RIGHTS No holder of any class of our stock has any preemptive right to purchase any of our securities. TRANSFER AGENT AND REGISTRAR The transfer agent and registrar for our common stock will be Registrar and Transfer Company. 57

SHARES ELIGIBLE FOR FUTURE SALE Upon consummation of the offering, we will have outstanding 24,782,422 shares of common stock or 25,719,922 shares if the underwriters' over-allotment option is exercised in full, in each case excluding shares underlying outstanding options. Of these shares, all of the shares sold in this offering (6,422,450 shares, or 7,359,950 shares if the underwriters' over-allotment option is exercised in full) will be freely tradeable without restriction or further registration under the Securities Act except for any shares purchased by an "affiliate," which will be subject to the limitations of Rule 144 of the Securities Act. As defined in Rule 144, an "affiliate" of an issuer is a person that directly, or indirectly through one or more intermediaries, controls, is controlled by or is under common control with the issuer. The remaining outstanding shares of common stock will be "restricted securities" as defined in Rule 144 and may not be resold in the absence of registration under the Securities Act or pursuant to an exemption from such registration, including exemptions provided by Rule 144. In addition, our executive officers, directors, and existing stockholders, who own all of the shares of our capital stock outstanding prior to this offering, have signed lock-up agreements in which they have agreed not to offer, sell, contract to sell or otherwise dispose of any common stock or any securities convertible into or exchangeable for common stock for a period of 180 days after the date of this prospectus without the prior written consent of Thomas Weisel Partners LLC. Immediately following this offering, the shares subject to the lock-up agreements will represent approximately 74% of the then outstanding shares of common stock (71% if the underwriters' over-allotment option is exercised in full). While the underwriters have indicated no present intention to waive these restrictions, were they to do so, up to approximately an additional 18,359,972 shares of our common stock could be available for sale during the period following the offering, which could harm our stock price or make it more difficult to sell our shares. Historically, factors that have led underwriters to waive lock-up restrictions on a case by case basis include bona fide gifts to charitable institutions and other small waivers which underwriters reasonably believe will have minimal effect on the trading price of the common stock of the applicable company. RULE 144 In general, under Rule 144, beginning 90 days after the date of this prospectus, a person who has beneficially owned restricted shares for at least one year, including persons who are affiliates, would be entitled to sell within any three-month period a number of shares that does not exceed the greater of: - 1% of the then outstanding shares of our common stock, approximately 247,824 shares immediately after this offering; or - the reported average weekly trading volume of our common stock during the four calendar weeks preceding a sale by such person. Sales under Rule 144 are also subject to manner-of-sale provisions, notice requirements and the availability of current public information. RULE 144(k) Under Rule 144(k), a person who has not been one of our affiliates during the 90 days preceding a sale, and who has beneficially owned the shares proposed to be sold for at least two years, is free to sell such shares without regard to the volume, manner-of-sale or certain other limitations contained in Rule 144. Upon completion of this offering, no holders of shares of our common stock will be eligible to freely sell shares under Rule 144(k). Prior to this offering, there has been no public market for our common stock and we can make no predictions about the effect, if any, that market sales of shares or the availability of shares for sale will have on the market price of our common stock prevailing from time to time. Future sales of substantial 58

amounts of our common stock in the public market, or the perception that such sales may occur, may cause the market prices of our common stock to decline. REGISTRATION RIGHTS After the 180-day period following the closing of this offering, the holders of 17,208,101 shares of our common stock will have rights which require us to register their shares for sale. See "Description of Capital Stock--Registration Rights." OPTIONS As of October 15, 2000, options to purchase 599,096 shares of our common stock were outstanding. At some time following the effectiveness of the offering chosen by the board of directors in its discretion, we intend to file a registration statement on Form S-8 under the Securities Act to register all of the shares of our common stock reserved for issuance under our 2000 Stock Option and Incentive Plan, our Employee Stock Purchase Plan and our 1996 Stock Option and Grant Plan. The filing of this registration statement will allow these shares, other than those held by members of management who are deemed to be affiliates, to be eligible for resale without restriction, subject to the lock-up period related to this offering, or further registration upon issuance to participants.

UNDERWRITING GENERAL Subject to the terms and conditions set forth in an agreement among the underwriters and us, each of the underwriters named below, through their representatives, Thomas Weisel Partners LLC, Dain Rauscher Incorporated and ING Barings LLC have severally agreed to purchase from us the aggregate number of shares of common stock set forth opposite its name below: NUMBER OF UNDERWRITERS SHARES - ------------ ---------- Thomas Weisel Partners LLC.................................. Dain Rauscher Incorporated.................................. ING Barings LLC............................................. ---------- Total................................................... 6,422,450 ========== Of the 6,422,450 shares to be purchased by the underwriters, 6,250,000 shares will be purchased from us and 172,450 shares will be purchased from our president as a selling stockholder. The underwriting agreement provides that the obligations of the several underwriters are subject to various conditions. The nature of the underwriters' obligations commits them to purchase and pay for all of the shares of common stock listed above if any are purchased. The underwriting agreement provides that we and the selling stockholder will indemnify the underwriters against liabilities specified in the underwriting agreement under the Securities Act or will contribute to payments that the underwriters may be required to make relating to these liabilities. Thomas Weisel Partners LLC expects to deliver the shares of common stock to purchasers on , 2000. OVER-ALLOTMENT OPTION We have granted a 30-day over-allotment option to the underwriters to purchase up to a total of 937,500 additional shares of our common stock from us at the initial public offering price, less the underwriting discounts and commissions payable by us, as set forth on the cover page of this prospectus. If the underwriters exercise this option in whole or in part, then each of the underwriters will be separately committed, subject to conditions described in the underwriting agreement, to purchase the additional shares of our common stock in proportion to their respective commitments set forth in the table above. DETERMINATION OF OFFERING PRICE Prior to this offering, there has been no public market for our common stock. The initial public offering price will be determined through negotiations between us and the representatives. In addition to prevailing market conditions, the factors to be considered in determining the initial public offering price will include: - the valuation multiples of publicly-traded companies that the representatives believe are comparable to us, - our financial information, 60

- our history and prospects and the outlook for our industry, - an assessment of our management, our past and present operations, and the prospects for, and timing of, our future revenues, - the present state of our development and the progress of our business plan, and - the above factors in relation to market values and various valuation measures of other companies engaged in activities similar to ours. We cannot assure you that an active or orderly trading market will develop for our common stock or that our common stock will trade in the public markets subsequent to this offering at or above the initial offering price. COMMISSIONS AND DISCOUNTS The underwriters propose to offer the shares of common stock directly to the public at the public offering price set forth on the cover page of this prospectus, and at this price less a concession not in excess of $ per share of common stock to other dealers specified in a master agreement among underwriters who are members of the National Association of Securities Dealers, Inc. The underwriters may allow, and the other dealers specified may reallow, concessions, not in excess of $ per share of common stock to these other dealers. After this offering, the offering price, concessions and other selling terms may be changed by the underwriters. Our common stock is offered subject to receipt and acceptance by the underwriters and to other conditions, including the right to reject orders in whole or in part. The following table summarizes the compensation to be paid to the underwriters by us and the expenses payable by us: TOTAL ------------------------------- WITHOUT WITH PER SHARE OVER-ALLOTMENT OVER-ALLOTMENT --------- -------------- -------------- Public offering price................................... $ $ $ Underwriting discount................................... Proceeds, before expenses, to us........................ Proceeds, before expenses, to our president as a selling stockholder........................................... INDEMNIFICATION OF THE UNDERWRITERS We and the selling stockholder will indemnify the underwriters against some civil liabilities, including liabilities under the Securities Act and liabilities arising from breaches of our representations and warranties contained in the underwriting agreement. If we are unable to provide this indemnification, we will contribute to payments the underwriters may be required to make in respect of those liabilities. RESERVED SHARES The underwriters, at our request, have reserved for sale at the initial public offering price up to 300,000 shares of common stock to be sold in this offering for sale to our employees and other persons designated by us. The number of shares available for sale to the general public will be reduced to the extent that any reserved shares are purchased. Any reserved shares not purchased in this manner will be offered by the underwriters on the same basis as the other shares offered in this offering. 61

NO SALES OF SIMILAR SECURITIES Our directors, officers, selling stockholder and other stockholders holding all of the outstanding shares of our capital stock prior to this offering have agreed or have a contractual obligation to agree, subject to specified exceptions, not to offer, sell, agree to sell, directly or indirectly, or otherwise dispose of any shares of common stock or any securities convertible into or exchangeable for shares of common stock without the prior written consent of Thomas Weisel Partners LLC for a period of 180 days after the date of this prospectus. We have agreed that for a period of 180 days after the date of this prospectus we will not, without the prior written consent of Thomas Weisel Partners LLC, offer, sell, or otherwise dispose of any shares of common stock, except for the shares of common stock offered in the offering and the shares of common stock issuable upon exercise of outstanding options and warrants on the date of this prospectus. INFORMATION REGARDING THOMAS WEISEL PARTNERS LLC Thomas Weisel Partners LLC, one of the representatives of the underwriters, was organized and registered as a broker-dealer in December 1998. Since December 1998, Thomas Weisel Partners LLC has been named as a lead or co-manager on 148 completed transactions and has acted as a syndicate member in an additional 129 public offerings of equity securities. Thomas Weisel Partners LLC does not have any material relationship with us or any of our officers, directors or other controlling persons, except with respect to its contractual relationship with us pursuant to the underwriting agreement entered into in connection with this offering. NASDAQ NATIONAL MARKET LISTING We have applied to have our common stock approved for quotation on the Nasdaq National Market under the symbol "HBIO." DISCRETIONARY ACCOUNTS The underwriters do not expect sales of shares of common stock offered by this prospectus to any accounts over which they exercise discretionary authority to exceed five percent of the shares offered. SHORT SALES, STABILIZING TRANSACTIONS AND PENALTY BIDS In order to facilitate this offering, persons participating in this offering may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock during and after this offering. Specifically, the underwriters may engage in the following activities in accordance with the rules of the U.S. Securities and Exchange Commission. SHORT SALES. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional shares from the issuer in the offering. The underwriters may close out any covered short position by either exercising their option to purchase shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. "Naked" short sales are any sales in excess of such over-allotment option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in the offering. 62

STABILIZING TRANSACTIONS. The underwriters may make bids for or purchases of the shares for the purpose of pegging, fixing or maintaining the price of the shares, so long as stabilizing bids do not exceed a specified maximum. PENALTY BIDS. If the underwriters purchase shares in the open market in a stabilizing transaction or syndicate covering transaction, they may reclaim a selling concession from the underwriters and selling group members who sold those shares as part of this offering. Stabilization and syndicate covering transactions may cause the price of the shares to be higher than it would be in the absence of these transactions. The imposition of a penalty bid might also have an effect on the price of the shares if it discourages resales of the shares. The transactions above may occur on the Nasdaq National Market or otherwise. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of the shares. If these transactions are commenced, they may be discontinued without notice at any time. LEGAL MATTERS The validity of the shares of common stock offered hereby will be passed upon for us by Goodwin, Procter & Hoar LLP, Boston, Massachusetts. Various legal matters related to the sale of the common stock offered hereby will be passed upon for the underwriters by Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., Boston, Massachusetts.

When the stock split referred to in note 20 of the notes to the consolidated financial statements has been consummated, we will be in a position to render the following report: INDEPENDENT AUDITORS' REPORT The Board of Directors Harvard Apparatus, Inc.: We have audited the accompanying consolidated balance sheets of Harvard Apparatus, Inc. and subsidiaries (the "Company") as of September 30, 2000, December 31, 1999 and 1998, and the related consolidated statements of operations, stockholders' equity (deficit) and comprehensive income (loss), and cash flows for the nine months ended September 30, 2000 and for each of the years in the three-year period ended December 31, 1999. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Harvard Apparatus, Inc. and subsidiaries at September 30, 2000, December 31, 1999 and 1998, and the results of their operations and their cash flows for the nine months ended September 30, 2000 and for each of the years in the three-year period ended December 31, 1999, in conformity with accounting principles generally accepted in the United States of America.

HARVARD APPARATUS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (1) ORGANIZATION On March 15, 1996, HAI Acquisition Corp. and its subsidiary, Guell Limited, purchased certain assets and assumed certain liabilities of the former Harvard Apparatus, Inc. and its subsidiary in the United Kingdom, Harvard Apparatus, Ltd. (the "Purchase"). For cash consideration of approximately $3,342,000 (including $342,000 of acquisition related expenses). The costs of the acquisition were allocated based on the fair market value of the assets acquired. The assets acquired consisted principally of cash of $441,000, accounts receivable of $1,397,000, inventories of $1,661,000, miscellaneous prepaid assets of $241,000, fixed assets of $846,000, and catalog costs of $366,000. The Company assumed liabilities of approximately $1,605,000. The acquisition was financed principally by issuing preferred stock of $1,500,000 and debt of $1,750,000. Assets acquired at the time of the purchase included 79% of the capital stock of Ealing Scientific Ltd. (Canada) and Ealing S.A.R.L., now Harvard Apparatus S.A.R.L. (France). The remainder of the capital stock of Ealing Scientific Ltd. and Ealing S.A.R.L. was also acquired directly from the stockholder at the time of the Purchase. After the date of the Purchase, HAI Acquisition Corp. and Guell Limited legally changed their names to Harvard Apparatus, Inc. and Harvard Apparatus, Ltd., respectively. The Company manufactures and distributes syringe pumps, ventilators, cell injectors, diffusion chambers and other products principally used in the toxicology, metabolism and efficacy testing of new drugs, as well as spectrophotometers and amino acid analyzers primarily used in molecular biology which are manufactured by Biochrom Ltd., a wholly owned subsidiary acquired during 1999. (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (A) PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of Harvard Apparatus, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. (B) INTERIM CONSOLIDATED FINANCIAL STATEMENTS The interim consolidated financial statements for the nine months ended September 30, 1999 are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the financial position and results of operations have been included in such unaudited consolidated financial statements. The results of operations for the nine months ended September 30, 2000 are not necessarily indicative of the results to be expected for the entire year. (C) CASH AND CASH EQUIVALENTS For purposes of the consolidated statements of cash flows, the Company considers all highly liquid instruments with original maturities of three months or less to be cash equivalents. (D) INVENTORIES Inventories are stated at the lower of cost or market. Cost is determined using a standard costing system which approximates the first-in, first-out (FIFO) method. F-8

HARVARD APPARATUS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (E) PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are stated at cost. Equipment under capital leases is stated at the present value of the minimum lease payments at the lease agreement date. Property, plant and equipment is depreciated using the straight-line method over the estimated useful lives of the assets as follows: Buildings................................................ 40 years Machinery and equipment.................................. 3-10 years Computer equipment....................................... 3-7 years Furniture and fixtures................................... 5-10 years Automobiles.............................................. 4-6 years (F) CATALOG COSTS Significant costs of product catalog design, development and production are capitalized and amortized over the expected useful life of the catalog (usually two to three years). Costs of drawings and design that were acquired at the purchase on March 15, 1996 are being amortized over their estimated useful life of six years. (G) INCOME TAXES Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. (H) FOREIGN CURRENCY TRANSLATION All assets and liabilities of the Company's foreign subsidiaries are translated at exchange rates in effect at year-end. Income and expenses are translated at rates which approximate those in effect on the transaction dates. The resulting translation adjustment is recorded as a separate component of stockholders' equity in other comprehensive income. (I) STOCK OPTIONS The Company accounts for stock options granted to employees in accordance with the requirements of Statement of Financial Accounting Standards (SFAS) No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION. As is permitted by this Statement, the Company has elected to account for stock options in accordance with the provisions of APB Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES and provide the additional disclosures that are required by SFAS No. 123. F-9

HARVARD APPARATUS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (J) USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of management's estimates. Such estimates include the determination and establishment of certain accruals and provisions, including those for inventory obsolescence, catalog cost amortization and reserves for bad debts. Actual results could differ from those estimates. (K) REVENUE RECOGNITION The Company recognizes revenue from product sales at the time of shipment. Product returns are estimated and provided for based on historical experience. (L) GOODWILL Goodwill, which represents the excess of purchase price over fair value of net assets acquired, is amortized on a straight-line basis over the expected periods to be benefited, ranging from 5 to 15 years. The Company continually evaluates whether events or circumstances have occurred that indicate that the remaining useful life of goodwill may warrant revision or that the remaining balance may not be recoverable. When factors indicate that goodwill should be evaluated for possible impairment, the Company estimates the undiscounted cash flow of the business segment, net of tax, over the remaining life of the asset in determining whether the asset is recoverable. Charges for impairment of goodwill would be recorded to the extent unamortized book value exceeds the related future discounted cash flow, net of tax. The discount factor would be the long-term debt rate currently obtainable by the Company. (M) IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF The Company uses the provisions of SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF. This statement requires that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. (N) EFFECT OF ACCOUNTING CHANGES In 1998, the Financial Accounting Standards Board issued SFAS 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. SFAS 133, which was deferred through the issuance of SFAS 137 and subsequently amended by SFAS 138, is effective for fiscal years beginning after June 15, 2000. SFAS 133 will be adopted on January 1, 2001. Its impact on the consolidated financial statements is still being evaluated, but is not expected to be material. F-10

HARVARD APPARATUS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (O) FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying value of the Company's cash and cash equivalents, trade accounts receivable, trade accounts payable and accrued expenses approximate their fair values because of the short maturities of those instruments. The carrying value of the Company's debt approximates its fair value because of the short maturities and/or interest rates which are comparable to those available to the Company on similar terms. (3) ACQUISITION OF BUSINESSES On June 30, 1998, the Company acquired certain assets of Medical Systems Corporation, a manufacturer and product developer of research medical equipment. Cash consideration of approximately $1,000,000 plus certain acquisition costs was paid for the assets. The costs of the acquisition were allocated on the basis of the estimated fair market value of the assets acquired. The net purchase price resulted in an allocation of $784,047 to goodwill and $281,506 to tangible net assets. On February 26, 1999, the Company acquired substantially all of the assets and certain liabilities of Pharmacia Biotech (Biochrom) Ltd. ("Biochrom"), a UK manufacturer and developer of spectrophotometers, amino acid analyzers and other related research equipment. Cash consideration of approximately $6,981,000 (including $502,000 of acquisition related expenses) was paid for the assets. The costs of the acquisition allocated on the basis of estimated fair market value of the assets acquired using the purchase method of accounting resulted in an allocation of $5,446,000 to goodwill and other intangibles. The assets acquired consisted of approximately $61,000 of accounts receivable, $1,039,000 of inventory, $100,000 of prepaid expenses, $612,000 of fixed assets, $372,000 of pension assets and liabilities assumed totaled approximately $649,000. On September 10, 1999, the Company acquired certain assets of Clark Electromedical Instruments, a manufacturer of glass capillaries and distributor of research equipment. Cash consideration of approximately $349,000 was paid for the assets. The costs of the acquisition allocated on the basis of estimated fair market value of the assets acquired using the purchase method of accounting resulted in an allocation of $288,000 to goodwill and other intangibles. On November 19, 1999, the Company acquired the NaviCyte diffusion chamber systems product line from NaviCyte, a wholly-owned subsidiary of Trega Biosciences, Inc. Cash consideration of approximately $390,000 (including $33,000 of acquisition related expenses) was paid for the assets. The costs of the acquisition allocated on the basis of estimated fair market value of the assets acquired and the purchase method of accounting resulted in an allocation of $333,000 to goodwill and other intangibles. On November 30, 1999, the Company acquired substantially all of the assets and certain liabilities of Hugo Sachs Elektronik a developer and manufacturer of perfusion systems for research. Cash consideration of approximately $568,000 was paid for the assets, net of cash acquired of $31,000. The costs of the acquisition allocated on the basis of estimated fair market value of the assets acquired and the purchase method of accounting resulted in an allocation of $89,000 to goodwill and other intangibles. F-11

HARVARD APPARATUS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (3) ACQUISITION OF BUSINESSES (CONTINUED) On May 19, 2000, the Company acquired substantially all of the assets of Biotronik, a manufacturer of Amino Acid Analyzers. Cash consideration of approximately $469,000 was paid for the assets (including approximately $12,000 of acquisition related expenses). The cost of the acquisition was allocated on the basis of fair market value of the assets acquired and the purchase method of accounting resulted in an allocation of $335,000 to goodwill. On July 14, 2000, the Company acquired substantially all of the assets of Amika Corporation, a manufacturer and distributor of sample preparation devices and consumables. Cash consideration of $3,096,000 was paid for the assets including approximately $61,000 of acquisition related expenses. The cost of the acquisition allocated on the basis of fair market value of the assets acquired and the purchase method of accounting resulted in an allocation of $3,011,000 to goodwill and other intangibles. The assets acquired consisted of approximately $85,000 of inventory. In addition, the Company acquired the right of first refusal to all new technologies developed and offered for sale by the predecessor Company for a period of four years on a fair value licensing arrangement. All acquisitions have been accounted for by the purchase method of accounting for business combinations. Accordingly, the accompanying consolidated statements of operations do not include any revenues or expenses related to these acquisitions prior to the respective acquisition dates. The following unaudited pro forma results of operations gives effect to the acquisition of Biochrom as if it had occurred at the beginning of fiscal 1998 (the effect of the other acquisitions are considered insignificant). Such pro forma information reflects certain adjustments including amortization of goodwill, interest expense, income tax effect and an increase in the number of weighted average shares outstanding. The pro forma information does not necessarily reflect the results of operations that would have occurred had the acquisition taken place as described and is not necessarily indicative of results that may be obtained in the future.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (7) LONG-TERM DEBT Long-term debt consists of the following: DECEMBER 31, --------------------- SEPTEMBER 30, 1998 1999 2000 -------- ---------- ------------- Subordinated debentures, at 13%, payable in quarterly installments through March 15, 2003................................ $787,500 $ 727,500 $ 477,500 Notes payable............................. -- 5,125,000 6,800,000 Capital lease obligations (note 10)....... 41,355 14,614 9,431 -------- ---------- ----------- 828,855 5,867,114 7,286,931 Less current installments................. 190,389 794,173 1,556,618 -------- ---------- ----------- $638,466 $5,072,941 $ 5,730,313 ======== ========== =========== On March 2, 1999, the Company entered into two loan agreements with two banks to borrow up to $5.5 million. The purpose of the loan agreements was to partially finance the acquisition of Biochrom (see note 3). Principal and interest are being paid in quarterly installments, with the final payment due in January 2002. The interest rate is determined by one of the banks base rate plus 1%, (10.5% and 9.5% at September 30, 2000 and December 31, 1999, respectively). The loans are secured by substantially all of the Company's assets. The loan agreements contain covenants relating to net income, debt service coverage and cash flow coverage. At September 30, 2000 and December 31, 1999, the Company was not in compliance with certain of its covenants. The Company has either received waivers from its banks or had the covenants amended by its banks. Financing costs of $221,074 were incurred in 1999. These costs were capitalized and are being amortized over the term of the loans. Amortization expense was $56,102 for the nine months ended September 30, 2000 and $63,442 for the year ended December 31, 1999. Aggregate annual principal payments on all long-term debt, excluding capital lease obligations, for the next five years and thereafter at September 30, 2000 are as follows: 2001........................................................ $ 1,550,004 2002........................................................ 4,449,996 2003........................................................ 777,500 2004........................................................ 500,000 Thereafter.................................................. -- ----------- $ 7,277,500 =========== (8) CONVERTIBLE AND REDEEMABLE PREFERRED STOCK During 1999, 48,500 shares of Series B convertible and redeemable preferred stock were issued to partially finance the acquisition of Biochrom (note 3). The net proceeds from this issuance were $925,174. The Company's Series B convertible redeemable preferred stock has a dividend preference over the Series A preferred stock, and as a result, no dividends shall be paid in respect of shares of F-14

HARVARD APPARATUS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (8) CONVERTIBLE AND REDEEMABLE PREFERRED STOCK (CONTINUED) Series A preferred stock unless all accrued dividends that become payable in respect of Series B preferred stock have been paid. The Series B redeemable convertible preferred stock is convertible at the option of the holder, at any time, into shares of common stock of the Company at a conversion rate of 19.71 shares of common stock for each share of Series B redeemable convertible preferred stock, subject to adjustment for subdivision of Series B preferred stock or any issuance of additional shares of Series B preferred stock. Redeemable preferred Series A stock pays quarterly cumulative dividends in arrears at a rate of approximately $0.26 per share. On March 3, 2000, convertible and redeemable preferred "B" stock started to accrue dividends at a rate of $1.44 that will be payable a year in arrears on March 3, 2001, and thereafter quarterly in arrears. In the event of any liquidation of the Company, the holders of the Company's redeemable preferred stock are entitled to be paid from the assets available for distribution to holders of the Company's capital stock $2,500,000, plus any related dividends that are accrued but unpaid at such time, prior to other stock distributions. Mandatory redemption requirements for the preferred stock are as follows: SERIES "A" SERIES "B" ------------ ------------ March 15, 2002....................................... $ 500,000 $ 333,320 March 15, 2003....................................... 500,000 333,320 March 15, 2004....................................... 500,000 333,320 ---------- ---------- $1,500,000 $1,000,000 ========== ========== (9) COMMON STOCK WARRANTS At September 30, 2000, December 31, 1999 and 1998, there were outstanding 8,509,905 warrants, which enable the holders to purchase a like amount of the Company's common stock for $0.0005 per share. The warrants were issued in connection with the issuance of Series A redeemable preferred stock (6,046,510 warrants) and subordinated debentures (2,463,395 warrants) that occurred on March 15, 1996. Commencing on March 15, 2002, the holders of the warrants may at any time require the Company to repurchase the warrants, or any common shares previously acquired from exercise of the warrants, for their fair market value as determined in good faith by the Company's board of directors. Such repurchase price would be repaid in 12 equal quarterly installments beginning on the first business day of the month following the surrender of the warrants or applicable shares of common stock. In 1999, 1998 and 1997 and for the nine months ended September 30, 2000 and 1999, $29,694,019, $1,379,460, $116,574, $70,920,242 and $7,402,457, respectively, has been recorded as interest expense to accrue the estimated amount of this potential liability in accordance with EITF 96-13, ACCOUNTING FOR DERIVATIVE FINANCIAL INSTRUMENTS INDEXED TO AND POTENTIALLY SETTLED IN, A COMPANY'S OWN STOCK. Future changes in the fair value of common stock warrants will also be recorded as interest expense. In September 2000, the holders of the warrants agreed to automatically terminate the requirement of the Company to repurchase the warrants in the event of an initial public offering of the Company's Common Stock.

The agreement was scheduled to expire on March 15, 2001 or at the time of any initial public offering of the Company's stock or other sale of a material portion of the Company's stock or assets, if such a transaction occurred before that date. As of September 30, 2000, the agreement with the former stockholder was rescinded. The related consulting expense amounted to $294,583 for the nine months ended September 30, 2000 and $258,437, $262,040 and $268,030 for the years ended December 31, 1999, 1998 and 1997, respectively.

Based upon the level of historical taxable income and projections for future taxable income over the periods during which deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences.

Those earnings are considered to be indefinitely reinvested and, accordingly, no related provision for U.S federal and state income taxes has been provided. Upon distribution of those earnings in the form of dividends or otherwise, the Company will be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes in the various foreign countries. (14) STOCK OPTION PLAN The Company has adopted a stock option plan (the "Plan") pursuant to which the Company's Board of Directors may grant stock options to employees. The Plan authorizes grants of options to purchase up to 4,072,480 shares of authorized but unissued stock. For the nine months ended September 30, 2000, and for the years ended December 31, 1999 and 1998, 2,254,272, 1,119,725 and 1,119,725 "Incentive Stock Options," and 1,812,295, 1,812,295 and 895,780 "Non-qualified Stock Options," respectively, had been granted to employees. The Incentive Stock Options become fully vested over a four year period, on a pro rata basis. The Non-qualified F-21

HARVARD APPARATUS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED) SEPTEMBER 30, 2000, DECEMBER 31, 1999 AND 1998 (14) STOCK OPTION PLAN (CONTINUED) Stock Options granted prior to 1999 only become vested if, prior to the end of the year 2000: a sale of substantially all of the Company's assets or capital stock occurs; or an initial public offering of the Company's common stock at a net price of not less than $1.42 per share; or the fair market value of the Company's common stock is otherwise determined to be, on a fully diluted basis, not less than $1.42 per common share. For non-qualified options granted under the plan during 1999, prior to an amendment to the plan dated September 29, 2000, the options were deemed to be vested and exercisable upon either (i) the sale of all or substantially all of the assets or capital stock of the Company for an actual or implied price per share of not less than $2.09 or (ii) an initial public offering of the Company's stock with a price per share of not less than $2.09 and gross proceeds to the Company of at least $15 million. On September 29, 2000, the vesting schedule was amended so that the options are vested and exercisable upon either (i) a sale of all or substantially all of the assets or capital stock of the Company for an actual or implied net price per share of Common Stock of not less than $2.09 or (ii) if the fair market value of the Company at any time prior to December 31, 2000 results in a per share valuation, on a fully diluted basis, of not less than $2.09 per share. As a result of the Plan amendment, the related options vested immediately as a per share valuation of $2.09 was attained. The Company applies APB Opinion No. 25 in accounting for the Plan. APB No. 25 requires no recognition of compensation expense for stock option awards when on the date of grant the exercise price is equal to the estimated fair market value of the Company's common stock and the number of options granted is fixed. During the nine months ended September 30, 2000, 1,134,547 stock options were granted to employees at an exercise price of $1.05 which was estimated to be less than the fair market value of the Company's common stock on the date of grant. Accordingly, compensation expense of $3,292,593 was recognized on these stock option grants. Additional compensation expense will be recognized in future periods over the four year vesting period of the options. The Company's 1996 and 1999 Non-qualified Stock Option awards are considered variable awards as the number of shares to be acquired by the employees is indeterminable at the date of grant. Accordingly, in 1999 and for the nine months ended September 30, 1999, the Company recognized compensation expense of $3,283,164 and $937,138, respectively, on the non-qualified Stock Options granted in 1996. At December 31, 1999, all non-qualified stock options granted in 1996 were fully vested because a per share valuation of $1.42 was attained. For the nine months ended September 30, 2000, the Company recognized compensation expense of $10,039,350 on the non-qualified options granted in 1999. On September 29, 2000, two employees exercised 563,942 non-vested options that were granted during 2000 for 563,942 shares of restricted common shares for cash consideration of $286 and two promissory notes amounting to $589,652 payable to the Company. The notes have a three-year maturity and a fixed interest rate of 10% per annum, compounded annually. The restricted stock becomes fully vested over a four-year period, on a pro rata basis. The estimated fair market value of the shares awarded on the original option date grant and on the date of exercise was estimated to be $6,767,310 of which $2,412,865 has been recognized as stock compensation expense for the nine months ended September 30, 2000. The remaining unearned compensation is being amortized to expense over the four year vesting period. Also on September 29, 2000, two employees of the Company exercised 916,514 fully vested options for cash of $465 and two promissory notes amounting to $958,298 payable to the Company. The notes have a three-year maturity and a fixed interest rate of 10% per annum, compounded annually. F-22

PHARMACIA & UPJOHN (CAMBRIDGE) LIMITED FORMERLY PHARMACIA BIOTECH (BIOCHROM) LIMITED NOTES TO THE ACCOUNTS YEAR ENDED 31ST DECEMBER 1998 1. ACCOUNTING POLICIES (a) BASIS OF ACCOUNTING Although it is intended that the Company shall cease to trade following the sale of its net assets on the 26th February 1999 (note 23), the accounts have been prepared on the going concern basis. This is because in the directors' opinion there is no material difference between the recoverable amounts of the assets and liabilities and their values in the balance sheet. The accounts have been prepared on the historical cost basis and in accordance with applicable Accounting Standards in the United Kingdom. A summary of the more important accounting policies which have been applied consistently is set out below: (b) DEPRECIATION OF TANGIBLE FIXED ASSETS The cost of fixed assets is their purchase cost, together with any incidental costs of acquisition. Depreciation is calculated using the straight line method to write off the fixed assets over their estimated useful lives as follows: Leasehold improvements...................................... -- 7 years Plant, machinery, equipment and tooling..................... -- 3-7 years Computer equipment.......................................... -- 5 years (c) DEFERRED TAXATION Provision is made using the liability method for the tax effect of all material timing differences between profits computed for taxation purposes and those stated in the accounts, except insofar as the timing differences are expected to continue for the foreseeable future. (d) FOREIGN CURRENCY Assets and liabilities in foreign currencies are translated to sterling at the rates of exchange ruling at the end of the financial year. Exchange differences resulting from changes in foreign currency rates are written off to the profit and loss account. (e) RESEARCH AND DEVELOPMENT EXPENDITURE Expenditure on research and development is written off to the profit and loss account during the year in which it is incurred. (f) OPERATING LEASES Costs in respect of operating leases are charged on a straight line basis in arriving at the operating profit. F-35

PHARMACIA & UPJOHN (CAMBRIDGE) LIMITED FORMERLY PHARMACIA BIOTECH (BIOCHROM) LIMITED NOTES TO THE ACCOUNTS YEAR ENDED 31ST DECEMBER 1998 1. ACCOUNTING POLICIES (CONTINUED) (g) STOCKS AND WORK IN PROGRESS Stocks are stated at the lower of cost and net realisable value. Cost in this context includes all attributable costs in getting each item to its present location and condition and, for finished goods and work in progress, a proportion of attributable overheads based on a normal level of activity. Net realisable value is the price at which stock can be sold in the normal course of business after allowing for the costs of realisation, and where appropriate, the costs of conversion from their existing state to a finished condition. Provision is made for obsolete, slow moving and defective stocks. (h) PENSION COSTS The Company operates a funded defined benefit pension scheme which is contracted out of the state scheme. The fund is valued every three years by a professionally qualified independent actuary, the rates of contribution payable being determined by the actuary. Pension costs are accounted for on the basis of charging the expected cost of providing pensions over the period during which the company benefits from the employees' services. The effects of variations from regular cost are spread over the expected average remaining service lives of members of the scheme. 2. TURNOVER Turnover represents the invoiced value of goods and services supplied during the year, less trade discounts and trade commissions, excluding Value Added Tax. Turnover arises from the principal activity of the Company and was derived from the following geographical areas by destination: 1998 1997 ------------------ ------------------ L L Europe............................................... 4,519,415 5,280,673 Asia and Australasia................................. 831,277 978,144 The Americas......................................... 1,693,897 2,301,527 Middle East and Africa............................... 57,187 139,600 ------------------ ------------------ Turnover is all UK by origin......................... 7,101,776 8,699,944 ================== ================== F-36

PENSION OBLIGATIONS The Company participates in a pension fund operated by Pharmacia Biotech UK, a branch office of Pharmacia Biotech Europe GmbH (previously Pharmacia Limited) providing benefits based on final pensionable pay. The assets of the fund are held separately from those of the Company being invested with investment managers in a managed fund. F-43

PHARMACIA & UPJOHN (CAMBRIDGE) LIMITED FORMERLY PHARMACIA BIOTECH (BIOCHROM) LIMITED NOTES TO THE ACCOUNTS (CONTINUED) YEAR ENDED 31ST DECEMBER 1998 20. PENSION OBLIGATIONS (CONTINUED) The total pension cost for the company is set out in note 7. The pension cost is assessed in accordance with the advice of an independent qualified actuary using the projected unit method. The most recent actuarial valuation adopted by the Trustees of the Pharmacia Limited Staff Superannuation Fund was as at 1 January 1997. The assumptions which had the most significant effect on the results of the valuation were those relating to: a) the future rate of investment return on the fund; b) the future rate at which members' salaries would increase; c) the rate of withdrawal from service. It was assumed that the long term rate of investment return would be at an average of 9% per annum and the rate of future salary increases would be at 7.5% per annum. The rate of withdrawal from service was selected at a rate slightly less than the rate experienced over the inter-valuation period. The most recent actuarial valuation adopted by the Trustees showed that the market value of the fund's assets was L5,564,000 and that the actuarial value of those assets represented 112% of the benefits that had accrued to members, after allowing for expected future increases in basic salary. The existing pension fund was formed in 1986 by the amalgamation of the Pharmacia Biotech Limited and Pharmacia LKB Biochrom Limited schemes. Following the net asset sale on 26 February 1999 (note 23), all Pharmacia Biotech active members (staff formerly employed by Pharmacia Biotech Limited) will transfer into the Nycomed Amersham Scheme. The remaining "Biochrom" active members will have the choice to transfer into the new Biochrom Limited pension scheme. All current and deferred members will remain in the Pharmacia Biotech UK Pension Fund which will be administered by Pharmacia & Upjohn at Milton Keynes. 21. RELATED PARTY TRANSACTIONS As a wholly owned subsidiary, whose results are included in the consolidated financial statements of Pharmacia & Upjohn, Inc. (see note 22), the company is exempt from the requirement to disclose details of transactions with other group companies. The Director regards Amersham Pharmacia Biotech AB ("APB") as a related party by virtue of the fact that the company's ultimate parent undertaking Pharmacia & Upjohn Inc. holds a 45% interest in APB and that there are certain common directorships. Sales to APB group companies amounted to L6,608,485 and the company was owed L1,010,761 as at 31 December 1998 in relation to trading balances. F-44

PHARMACIA & UPJOHN (CAMBRIDGE) LIMITED FORMERLY PHARMACIA BIOTECH (BIOCHROM) LIMITED NOTES TO THE ACCOUNTS (CONTINUED) YEAR ENDED 31ST DECEMBER 1998 22. ULTIMATE AND IMMEDIATE PARENT UNDERTAKING The directors regard Pharmacia & Upjohn, Inc, a company incorporated in the USA, as the ultimate parent and controlling undertaking. Copies of the ultimate parent's consolidated financial statements may be obtained from: Pharmacia & Upjohn, Inc 7000 Portage Road, Kalamazoo Michigan 49001, USA According to the register kept by the company, Pharmacia & Upjohn Limited, a company registered in England and Wales, has a 100% interest in the equity capital of the company at 31 December 1998. 23. POST BALANCE SHEET EVENTS On the 26th February 1999, the Company sold the majority of its net assets to Biochrom Limited for a consideration of US Dollars 6,362,574. Following this, the Company will cease to trade. 24. SUMMARY OF DIFFERENCES BETWEEN UK AND US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES ("GAAP") The company has prepared financial statements in accordance with UK GAAP. There are no reconciling differences between US and UK GAAP related to the equity shareholders' funds as of 31 December 1997 and 1998 and the net income for the years ended 31 December 1997 and 1998. The financial statements reflect all costs of doing business including costs incurred by other group companies on behalf of the Company. As of 31 December 1997 and 1998 the following other differences exist: DEFERRED TAXATION Under UK GAAP, provision for deferred tax is only required to the extent that it is probable that a taxation liability or asset will crystallise, in the foreseeable future, as a result of timing differences between taxable profits and accounting profit, with provision made at the known tax rate. Under US GAAP, full provision for deferred tax is required to the extent that accounting profit differs from taxable profit due to temporary differences. Provision is made at the tax rate in effect at the time the difference is likely to reverse. A valuation adjustment is made against deferred tax assets when it is more likely than not that a deferred tax asset will not be realised. As such, provision for the taxable losses carried forward of L46,451 would be provided with a valuation allowance for the full amount, resulting in no net impact on the profit and loss account or shareholders' equity, as of 31 December 1998. Provision for the taxable losses carried forward of L66,380 would be provided with a valuation allowance for the full amount, resulting in no net impact on the profit and loss account or shareholders' equity, as of 31 December 1997.

SUMMARY OF DIFFERENCES BETWEEN UK AND US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES ("GAAP") (CONTINUED) CASH FLOW STATEMENTS The cash flow statement is prepared in accordance with United Kingdom Financial Reporting Standard 1 "FRS 1 (Revised 1996)", whose objective and principles are similar to those set out in SFAS No.95, "Statement of Cash Flows". The principal differences between the standards relate to classification. Under FRS 1 (Revised 1996), the company presents its cash flows for (a) operating activities, (b) returns on investments and servicing of finance, (c) taxation, (d) capital expenditure and financial investment, (e) equity dividends paid, (f) management of liquid resources and (g) financing. SFAS No.95 requires only three categories of cash flow activity being (a) operating, (b) investing and (c) financing. Cash flows from taxation and returns on investments and servicing of finance under FRS 1 (Revised 1996) would be included as operating activities under SFAS No.95, capital expenditure and financial investment would be included as investing activities, and equity dividends paid would be included as a financing activity under SFAS No.95. Under FRS 1 (Revised 1996) cash comprises cash in hand and deposits repayable on demand, less overdrafts repayable on demand, and liquid resources comprise current asset investments held as readily disposable stores of value. Under SFAS No.95 cash equivalents, comprising short-term highly liquid investments, generally with original maturities of three months or less, are grouped together with cash. Cash equivalents exclude overdrafts. There are no differences between cash as stated under UK GAAP and cash and cash equivalents as stated under US GAAP at 31 December 1997 and 1998. Set out below, for illustrative purposes, is a summary of cash flows under US GAAP.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES Set forth in chronological order below is information regarding the number of shares of capital stock issued by us since October 15, 1997. Also included is the consideration, if any, received by us for such shares. There was no public offering in any such transaction and we believe that each transaction was exempt from the registration requirements of the Securities Act of 1933 by reason of Section 4(2) thereof, based on the private nature of the transactions and the financial sophistication of the purchasers, all of whom had access to complete information concerning us and acquired the securities for investment and not with a view to the distribution thereof. In addition, we believe that the transactions described below with respect to issuances and option grants to our employees and directors were exempt from the registration requirements of said Act by reason of Section 4(2) of said Act or Rule 701 promulgated thereunder. (a) ISSUANCE OF CAPITAL STOCK (i) In 1999, we issued an aggregate of 48,500 shares of our series B convertible preferred stock to Ascent Venture Partners, L.P.

UNDERTAKINGS The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof.

The number of authorized shares of the class of Undesignated Preferred Stock may from time to time be increased or decreased (but not below the number of shares outstanding) by the affirmative vote of the holders of a majority of the outstanding shares of Common Stock entitled to vote, without a vote of the holders of the Preferred Stock (subject to the terms of the Series A Preferred Stock and the Series B Preferred Stock and except as otherwise provided in any certificate of designations of any series of Undesignated Preferred Stock). The powers, preferences and rights of, and the qualifications, limitations and restrictions upon, each class or series of stock shall be determined in accordance with, or as set forth below in, this Article IV. A. COMMON STOCK Subject to all the rights, powers and preferences of the Preferred Stock and except as provided by law or in this Article IV (or in any certificate of designations of any series of Undesignated Preferred Stock): (a) the holders of the Common Stock shall have the exclusive right to vote for the election of directors of the Corporation (the "Directors") and on all other matters requiring stockholder action, each outstanding share entitling the holder thereof to one vote on each matter properly submitted to the stockholders of the Corporation for their vote; PROVIDED, HOWEVER, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate (or on any amendment to a certificate of designations of any series of Undesignated Preferred Stock) that alters or changes the powers, preferences, rights or other terms of one or more outstanding series of Undesignated Preferred Stock if the holders of such affected series are entitled to vote, either separately or together with the holders of one or more other such series, on such amendment pursuant to this Certificate (or pursuant to a certificate of designations of any series of Undesignated Preferred Stock) or pursuant to the DGCL; (b) dividends may be declared and paid or set apart for payment upon the Common Stock out of any assets or funds of the Corporation legally available for the payment of 2

B. SERIES A REDEEMABLE PREFERRED STOCK AND SERIES B CONVERTIBLE PREFERRED STOCK. 1. DESIGNATION; NUMBER OF SHARES. A total of 469,300 shares of the Corporation's Preferred Stock shall be designated as Series A Redeemable Preferred Stock, $0.01 par value per share (the "Series A Preferred Stock"). A total of 48,500 shares of the Corporation's Preferred Stock shall be designated as Series B Convertible Preferred Stock, $0.01 par value per share (the "Series B Preferred Stock") (the Series A Preferred Stock and the Series B Preferred Stock are hereinafter sometimes referred to collectively in this Section B as the "Preferred Stock"). The relative rights, preferences, restrictions and other matters relating to the Preferred Stock are as follows: 2. DIVIDENDS. (a) CUMULATIVE; RATE. The holders of the outstanding shares of Preferred Stock shall be entitled to receive cash dividends, when, as and if declared by the Board of Directors, out of assets which are legally available for the payment of such dividends and contingent upon and limited to the extent of earnings. Dividends shall be cumulative and will accrue: (i) on each share of Series A Preferred Stock from the date of issue thereof and (ii) on each share of Series B Preferred Stock from the later of (x) the date of issue thereof and (y) March 3, 2000, in each case, whether or not earned or declared by the Board of Directors. Except as otherwise set forth herein, the annual dividend rate per share: (1) of Series A Preferred Stock shall be $.25569998 (which amount shall be subject to equitable adjustment whenever there shall occur a stock dividend, stock split, combination, reorganization, recapitalization, reclassification or other similar event involving a change in the capital structure of the Corporation (hereinafter an "Equitable Adjustment")) and (2) of Series B Preferred Stock shall be $1.443 (subject to Equitable Adjustment). Dividends on the Preferred Stock shall be payable on each January 1, April 1, July 1 and October 1 in each year; PROVIDED, HOWEVER, that no dividend shall be payable until: (i) in the case of the Series A Preferred Stock, March 15, 1997 and (ii) in the case of the Series B Preferred Stock, March 3, 2001. In addition, the Series B Preferred Stock shall rank senior to the Series A Preferred Stock with respect to dividends, and as a result, no dividend shall be paid in respect of shares of the Series A Preferred Stock unless all accrued dividends that have become payable in respect of the Series B Preferred Stock shall have been paid. In the event a dividend is not paid when due (the "Dividend Payment Date") the annual dividend rate per share: (a) of the Series A Preferred Stock shall be $.319624976 (which amount shall be subject to Equitable 3

Adjustment) and (b) of the Series B Preferred Stock shall be $1.80375 (which amount shall be subject to Equitable Adjustment), in each case accruing from the first day of the dividend period immediately succeeding the dividend period in which such unpaid dividend accrued and continuing until all accrued dividends on such series of Preferred Stock have been paid in full, whereupon the dividend rate shall return to the rate specified in clause (1) or (2) above, as applicable. Dividends payable on the Preferred Stock for any period less than a full quarter shall be computed on the basis of the actual number of days elapsed and a 360-day year, consisting of four 90-day quarters. Notwithstanding anything to the contrary contained herein, all accrued and unpaid dividends shall be payable upon liquidation, dissolution or winding up of the Corporation within the meaning of Section B.3 hereof or upon redemption as provided in Section B.5 hereof. (b) RESTRICTIONS. (i) SERIES A PREFERRED STOCK. Unless all accrued dividends on each share of the Series A Preferred Stock shall have been paid, no dividend shall be paid or declared, and no distribution shall be made on any Series A Junior Stock (as defined below) (other than a stock dividend on Common Stock solely in the form of additional shares of Common Stock). Furthermore, except to the extent in any instance written approval is provided by the holders of at least a majority of the outstanding shares of Series A Preferred Stock (the "Majority A Holders"), the Corporation shall not declare or pay any dividends, or purchase, redeem, retire, or otherwise acquire for value any of its capital stock ranking junior to the Series A Preferred Stock (or rights, options or warrants to purchase such shares), now or hereafter outstanding (collectively, "Series A Junior Stock"), return any capital to any stockholders holding any Series A Junior Stock as such, or make any distribution of assets on such Series A Junior Stock, or permit any subsidiary to do any of the foregoing, except that wholly-owned subsidiaries may declare and make payment of cash and stock dividends, return capital and make distributions of assets to the Corporation. (ii) SERIES B PREFERRED STOCK. Unless all accrued dividends on each share of the Series B Preferred Stock shall have been paid, no dividend shall be paid or declared, and no distribution shall be made on any Series B Junior Stock (as defined below) (other than a stock dividend on Common Stock solely in the form of additional shares of Common Stock). Furthermore, except to the extent in any instance written approval is provided by the holders of at least a majority of the outstanding shares of Series B Preferred Stock (the "Majority B Holders"), the Corporation shall not declare or pay any dividends, or purchase, redeem, retire, or otherwise acquire for value any of its capital stock ranking junior to the Series B Preferred Stock, including for all purposes unless otherwise specifically set forth herein, the Series A Preferred Stock (or rights, options or warrants to purchase such shares) now or hereafter outstanding (collectively, "Series B Junior Stock"), return any capital to any stockholders holding any Series B Junior Stock as such, or make any distribution of assets on such Series B Junior Stock, or permit any subsidiary to do any of the foregoing, except that wholly-owned subsidiaries may declare and make payment of cash and stock dividends, return capital and make distributions of assets to the Corporation. 4

(iii) GENERAL. Nothing in this Section B.2(b) shall prevent the Corporation from: (1) effecting a stock split or declaring or paying any dividend consisting of shares of any class of capital stock to the holders of shares of such class of capital stock; or (2) complying with any specific term or provision of the Preferred Stock, or any other class or series of the Corporation's capital stock ranking senior to or on parity with the Preferred Stock; or (3) repurchasing any security issued to any officer, employee, director or consultant of the Corporation pursuant to the Corporation's 1996 Stock Option and Grant Plan, or any other stock option plan approved by the Majority A Holders and the Majority B Holders, pursuant to any rights of first refusal or repurchase rights of the Corporation under such plan(s); or (4) repurchasing any security required to be repurchased pursuant to and in accordance with the provisions of the Amended and Restated Securityholders' Agreement among the Corporation and certain stockholders of the Corporation named therein dated as of March 2, 1999 (as amended, modified and supplemented from time to time, the "Securityholders' Agreement"); or (5) complying with any specific term or provision of the warrants (the "Warrants") purchased pursuant to the Investment and Stockholders' Agreement dated March 15, 1996 among the Corporation and certain stockholders of the Corporation (the "Investment Agreement") OTHER THAN the repurchase of the Warrants or any other payment in respect thereof; or (6) paying dividends on, purchasing, redeeming, retiring or otherwise acquiring for value any shares of the Series B Preferred Stock, which Series B Preferred Stock, except as specifically set forth herein, shall rank senior to the Series A Preferred Stock with respect to dividends, liquidation and/or redemption. 3. LIQUIDATION, DISSOLUTION OR WINDING UP. (a) TREATMENT AT LIQUIDATION, DISSOLUTION OR WINDING UP. Subject to the rights and preferences of any class or series of Preferred Stock senior to, or on parity with, the Series A Preferred Stock and/or the Series B Preferred Stock with respect to liquidation preferences, in the event of any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, or in the event of its insolvency, before any distribution or 5

payment is made to any holders of: (i) Series B Junior Stock, the holders of each share of Series B Preferred Stock shall be entitled to be paid out of the assets of the Corporation available for distribution to the holders of the Corporation's capital stock, whether such assets are capital, surplus or earnings, an amount equal to $20.6185567 per share of Series B Preferred Stock (which amount shall be subject to Equitable Adjustment) plus all accrued and unpaid dividends thereon, whether or not earned or declared, up to and including the date full payment shall be tendered to the holders of the Series B Preferred Stock with respect to such liquidation, dissolution or winding up and (ii) Series A Junior Stock, the holders of each share of Series A Preferred Stock shall be entitled to be paid out of the assets of the Corporation available for distribution to holders of the Corporation's capital stock, whether such assets are capital, surplus or earnings, an amount equal to $3.19624976 per share of Series A Preferred Stock (which amount shall be subject to Equitable Adjustment) plus all accrued and unpaid dividends thereon, whether or not earned or declared, up to and including the date full payment shall be tendered to the holders of the Series A Preferred Stock with respect to such liquidation, dissolution or winding up. After payment shall have been made in full to the holders of the Preferred Stock as set forth above, or funds necessary for such payment shall have been irrevocably set aside by the Corporation in trust for the account of holders of the Preferred Stock so as to be available for such payment, the remaining assets available for distribution shall be distributed ratably among the holders of the Common Stock and any other class of Series A Junior Stock. If, in connection with any such liquidation, dissolution or winding up, the funds of the Corporation legally available to be paid to the holders of Preferred Stock are insufficient to pay in full the liquidation preference owing to the holders of a series of Preferred Stock, the holders of shares of any such series shall share ratably in funds available to be paid in respect of such series of Preferred Stock (in the priority set forth above in the preceding paragraph) according to the respective amounts which would be payable with respect to the number of shares owned by them if all the shares of such series were paid the full amount of the liquidation preference of such series. (b) In the event that the Corporation undertakes any transaction, the result of which is: (i) a consolidation or merger of the Corporation with or into another corporation or entity (other than a wholly-owned subsidiary) in which an unaffiliated third-party owns a majority of the outstanding capital stock of the surviving corporation or entity, (ii) the sale, transfer or other disposition of all or substantially all of the assets or all or a majority of the outstanding capital stock of the Corporation to an unaffiliated third party, or (iii) the consummation of a public offering of the Common Stock pursuant to an effective registration statement filed pursuant to the Securities Act in a transaction that does not meet the criteria of a "Qualified Public Offering" as set forth in Section B.9(c) hereof (each of (i), (ii) and (iii), a "Liquidation Event"), then pursuant to Section B.5(a)(iv) hereof, any holder of Series B Preferred Stock may elect to treat such Liquidation Event as a liquidation, dissolution or winding up within the meaning of Section B.3(a) above, and as a result of any such election, such holder of Series B Preferred Stock shall be entitled to the amount set forth in Section B.3(a) above in respect of each of its shares of Series B Preferred Stock. 6

(c) DISTRIBUTIONS OTHER THAN CASH. Whenever the distribution provided for in this Section B.3 shall be payable in property other than cash, the value of such distribution shall be the fair market value of such property, as determined in good faith by two-thirds of the members of the Board of Directors of the Corporation. Any dispute that arises in connection with the Board of Directors' determination of fair market value shall be resolved as set forth in Section B.10. 4. VOTING RIGHTS. (a) Except as otherwise expressly provided herein or as required by law, each holder of: (i) Series A Preferred Stock shall be entitled to one vote for each share of Series A Preferred Stock held of record by such holder, as if such share were a share of Common Stock and (ii) Series B Preferred Stock shall be entitled to the number of votes per share of Series B Preferred Stock as shall equal the number of shares of Common Stock into which such share of Series B Preferred Stock is then convertible. Notwithstanding the foregoing, with respect to the Series A Preferred Stock, if (i) the sum of (x) the total number of shares of Series A Preferred Stock issued to any original holder thereof (the "Original Holder Shares") pursuant to the Investment Agreement PLUS (y) the aggregate number of shares of Common Stock issued by the Corporation upon exercise of any Warrant issued by the Corporation to such original holder pursuant to the Investment Agreement (whether or not subsequently transferred by the original holder), exceeds (ii) the maximum number of shares of Common Stock, in the aggregate, as adjusted, theretofore issued and thereafter issuable to such holder upon exercise of such Warrant (the "Maximum Voting Limit"), then the number of votes to which any holder of such Original Holder Shares (including the original holder and any transferee of such shares) is entitled shall be reduced by the amount of such excess on a share for share basis (and if there is more than one holder of the Original Holder Shares, such reduction shall be effected on a pro-rata basis). (b) Except as otherwise expressly provided herein or as required by law, the holders of Series A Preferred Stock, Series B Preferred Stock and Common Stock shall vote together as a single class on all matters (with each share of Preferred Stock having such number of votes as are specified above in subparagraph (a)). (c) Fractional votes shall not be permitted and any fractional voting rights resulting from any of the above shall be rounded to the nearest whole number (with one-half being rounded upward). 5. REDEMPTION. (a) REDEMPTION EVENTS. (i) SCHEDULED REDEMPTION OF SERIES A PREFERRED STOCK AND SERIES B PREFERRED STOCK. On March 15 in each of 2002, 2003 and 2004, the Corporation shall redeem the number of then outstanding shares of Series A Preferred Stock set forth below (subject to 7

Equitable Adjustment) for the Series A Redemption Price (as defined below) and the number of then outstanding shares of Series B Preferred Stock set forth below (subject to Equitable Adjustment) for the Series B Redemption Price (as defined below). For the purposes of any redemption of Preferred Stock pursuant to this Section B.5(a)(i), the Series A Preferred Stock shall be on parity with the Series B Preferred Stock and shall not be included within the term "Series B Junior Stock."

(iii) AUTOMATIC REDEMPTION OF SERIES A PREFERRED STOCK UPON MERGER OR REORGANIZATION. Immediately prior to and conditioned upon the consummation of the closing of (A) any acquisition of the Corporation by means of a merger or other form of corporate reorganization in which the outstanding shares of the Corporation are exchanged for securities or other consideration issued or paid, or caused to be issued or paid, by the acquiring company or its subsidiary and following which the stockholders of the Corporation own, in the aggregate, less than fifty percent (50%) of the total issued and outstanding voting capital stock of the surviving entity, or (B) any sale of all or substantially all of the assets of the Corporation and its subsidiaries, or (C) any sale of a material and substantial asset or group of assets of the Corporation or of any subsidiary of the Corporation other than in the ordinary course of business (including, without limitation, any sale of the capital stock of any subsidiary of the Corporation), whether in one transaction or in a series of transactions, in which the aggregate consideration paid to the Corporation by the purchaser or purchasers of such asset or group of assets exceeds $2,000,000, the Corporation shall redeem each outstanding share of Series A Preferred Stock for the Series A Redemption Price. (iv) OPTIONAL REDEMPTION BY ANY HOLDER OF SERIES B PREFERRED STOCK UPON MERGER, REORGANIZATION OR NON-QUALIFIED IPO. Any Liquidation Event (as defined in Section B.3(b) above) shall, at the election of a holder of Series B Preferred Stock, be deemed to be a liquidation, dissolution or winding up within the meaning of Section B.3(a), and as a result of any such election, such holder of Series B Preferred Stock shall be entitled to the 8

amount set forth in Section B.3(a) above in respect of each of its shares of Series B Preferred Stock. (b) EVENTS OF DEFAULT; CONTROL OF THE BOARD OF DIRECTORS. If any Event of Default (as hereinafter defined) shall have occurred and be continuing, the Majority A Holders and/or the Majority B Holders may give the Corporation a written notice (an "Event of Default Notice") requiring: (i) the Corporation to repurchase the outstanding shares of Series A Preferred Stock for the Series A Redemption Price, and/or the outstanding shares of Series B Preferred Stock for the Series B Redemption Price, as applicable, in each case plus interest at the rate of ten percent (10%) per annum on any accrued and unpaid dividends outstanding as of the date of such Event of Default Notice, accruing from the date on which such dividend was payable, and/or (ii) the Board of Directors be reconstituted as provided in the immediately succeeding sentence. If the Corporation fails to repurchase outstanding shares of either class of Preferred Stock as required under Section B.5(a) above or fails to repurchase the shares of either class of Preferred Stock pursuant to this Section B.5(b) within thirty (30) days following its receipt of the Event of Default Notice from the Majority A Holders and/or the Majority B Holders, as the case may be, or in the event the Event of Default Notice so requires, the holders of the Series A Preferred Stock and Series B Preferred Stock, voting together as a single class (in accordance with Section B.4(a) above) shall be entitled to elect the smallest number of directors which shall constitute a majority of the authorized number of directors of the Corporation, and the holders of Common Stock shall be entitled to elect the remaining directors. Within two (2) business days after the failure of the Corporation to repurchase the outstanding shares of either class of Preferred Stock as aforesaid, or in the event the Event of Default Notice so requires, the Corporation shall call a special meeting of stockholders for the election of directors to be held as promptly as practicable. At such meeting and at any other meeting held while the holders of the Preferred Stock have such class voting rights, the holders of a majority of the voting power of the Preferred Stock (as set forth in the preceding paragraph) present in person or by proxy shall be sufficient to constitute a quorum for the election of directors as herein provided. In the case of any vacancy in the office of a director elected by a class of stock under this Section B.5(b), the remaining directors elected by such class may elect a successor to fill the vacancy. Any director elected pursuant to this Section B.5(b) may, at a meeting called for the purposes, be removed with or without cause by the vote of the holders of a majority of the shares of the class of stock that elected such director. Any of the following shall constitute an Event of Default hereunder: (i) The failure by the Corporation to pay any dividend in accordance with the terms of the Series A Preferred Stock or Series B Preferred Stock when due, which failure is not remedied within sixty (60) days after the Corporation's receipt of written notice 9

thereof from the Majority A Holders or the Majority B Holders, as applicable ("Default Notice"). (ii) The failure of the Corporation to observe or perform any covenant or agreement contained in any of Sections 8.2, 8.3, 8.4, 8.5 or 8.6 of the Securityholders' Agreement, which failure is not remedied within thirty (30) days after the Corporation's receipt of a Default Notice with respect thereto, provided, however, in the case of Section 8.2 of the Securityholders' Agreement, it shall not be an Event of Default hereunder for so long as the Corporation is using commercially reasonable efforts to satisfy such Section 8.2; (iii) The failure of the Corporation to observe or perform any covenant or agreement contained in any of Articles IV, VI or VII or Sections 8.1 or 8.7 of the Securityholders' Agreement; PROVIDED, HOWEVER, if any such failure is subject to cure within ten (10) business days of such failure, then it shall not be an Event of Default hereunder, until the expiration of such ten (10) business days so long as the Corporation is diligently seeking to cure such failure during such period; (iv) The breach by the Corporation of any material covenant or agreement (other than a breach described in clause (i) above, or clause (v) below) contained in these Restated Articles of Organization, including, without limitation, the failure to redeem any shares of either series of Preferred Stock required to be redeemed as provided in this Section B.5; (v) The breach by the Corporation of any covenant or agreement contained in these Restated Articles of Organization (other than a breach described in clause (i) or (iv) above) which such breach is not remedied within thirty (30) days after the Corporation's receipt of a Default of Notice with respect thereto from the Majority A Holders or the Majority B Holders, as applicable; (vi) In the event (A) Chane Graziano (1) dies, (2) is disabled for a period of time in excess of six (6) months and is unable to perform his duties for the Corporation in all material respects or (3) ceases to be an employee of the Corporation for any reason (any of clauses (1), (2) or (3), a "Triggering Event") and (B) either (I) a replacement for Mr. Graziano mutually acceptable to the Corporation, the Majority A Holders and the Majority B Holders is not installed within ninety (90) days of the Triggering Event or (II) a replacement for Mr. Graziano acceptable to the Majority A Holders and the Majority B Holders is not installed within one-hundred and twenty (120) days of the Triggering Event; (vii) The failure by the Corporation to repurchase any securities (including without limitation any warrants) required to be so repurchased in accordance with the terms thereof; PROVIDED THAT it shall not be an Event of Default hereunder if such failure by the Corporation is a result of any provision in these Restated Articles of Organization or the lack of consent by the holders of Series A Preferred Stock and/or Series B Preferred Stock; or 10

(viii) An Event of Default (as defined in the Securityholders' Agreement) shall have occurred. Notwithstanding anything contained herein to the contrary, the rights of the holders of the Preferred Stock as aforesaid to elect a majority of the Board of Directors hereunder shall not preclude such holders from seeking and obtaining any other remedy, legal or equitable, with respect to their rights of redemption set forth hereunder. (c) OPTIONAL REDEMPTION BY THE CORPORATION OF PREFERRED STOCK. All or any of the shares of Preferred Stock shall be redeemable at any time or from time to time after issuance, in whole or in part, at the option of the Corporation by vote or approval of (i) two-thirds of the members of the Board of Directors, (ii) the Majority A Holders and (iii) the Majority B Holders. Any such redemption of Preferred Stock by the Corporation under this Section B.5(c) shall be made pro-rata among all outstanding shares of Series A Preferred Stock and Series B Preferred Stock on a combined basis (unless, with respect to shares of Series B Preferred Stock only, such redemption is waived in accordance with Section B.5(g) hereof), and for the purposes of any redemption of Preferred Stock pursuant to this Section B.5(c), the Series A Preferred Stock shall be on parity with the Series B Preferred Stock and shall not be included within the term "Series B Junior Stock." Any redemption of Series A Preferred Stock under this Section B.5(c) shall be at the Series A Redemption Price. Any Redemption of Series B Preferred Stock under this Section B.5(c) shall be at the price specified in Section B.3(a) above. (d) PRO RATA. If any redemption of either series of Preferred Stock shall be of less than all of the then outstanding shares of such series of Preferred Stock, such redemption shall be made so that the number of shares of such series of Preferred Stock held by each registered owner shall be reduced in an amount which shall bear the same ratio to the total number of shares of such series of Preferred Stock being so redeemed as the number of shares of such series of Preferred Stock then held by such registered owner bears to the aggregate number of shares of such series of Preferred Stock then outstanding; PROVIDED, HOWEVER, that the Corporation shall not be required to redeem fractional shares, and the shares of a series of Preferred Stock to be redeemed from any holder thereof may be rounded to the nearest full share. (e) (i) SERIES A REDEMPTION PRICE. The redemption price for each share of Series A Preferred Stock (the "Series A Redemption Price") redeemed pursuant to this Section B.5 shall be $3.19624976 (which amount shall be subject to Equitable Adjustment) plus all accrued and unpaid dividends thereon, if any, whether or not earned or declared, on such shares up to and including the date fixed for redemption. (ii) SERIES B REDEMPTION PRICE. The redemption price for each share of Series B Preferred Stock (the "Series B Redemption Price") redeemed pursuant to Section B.5(a)(i) or B.5(b) above (but not B.5(a)(iv) or B.5(c) above for which the price specified in Section B.3(a) shall apply) shall be equal to the greater of (1) $20.6185567 (which amount 11

shall be subject to Equitable Adjustment) plus all accrued and unpaid dividends thereon, if any, whether or not earned or declared, on such shares up to and including the date fixed for redemption or (2) the amount per share that would be received if each share of Series B Preferred Stock were converted into Common Stock and such Common Stock were redeemed at its fair market value, as determined in good faith by two-thirds of the members of the Board of Directors of the Corporation, but without any discount for lack of control. Any dispute between the Corporation and any holder or holders representing at least 10% of the outstanding shares of Series B Preferred Stock that arises in connection with such determination of fair market value shall be resolved as set forth in Section B.10. (f) REDEMPTION NOTICE. At least thirty (30) days but no more than sixty (60) days prior to each date fixed for redemption (the "Redemption Date") pursuant to Section B.5(a) or B.5(c) hereof, or promptly following the Corporation's receipt of the Event of Default Notice pursuant to Section B.5(b), the Corporation shall mail, postage prepaid, written notice (the "Redemption Notice") to each holder of record of the each series of Preferred Stock, at its address shown on the records of the Corporation; PROVIDED, HOWEVER, that the Corporation's failure to give such Redemption Notice shall in no way affect its obligation to redeem the shares of Preferred Stock as provided in Sections B.5(a) and B.5(b) hereof. The Redemption Notice shall contain the following information: (i) the number of shares of each series of Preferred Stock held by the holder which shall be redeemed by the Corporation and the total number of shares of each series of Preferred Stock held by all holders to be so redeemed; (ii) the Redemption Date, the Series A Redemption Price and the Series B Redemption Price; and (iii) that the holder is to surrender to the Corporation, at the place designated therein, its certificate or certificates representing the shares of Preferred Stock to be redeemed. (g) WAIVER OF REDEMPTION. (i) SERIES A PREFERRED STOCK. The Corporation's obligation to redeem all or any portion of the shares of Series A Preferred Stock pursuant to Sections B.5(a) or B.5(b) may be waived in whole or in part (such partial waiver to apply on a pro rata basis to all holders of shares of Series A Preferred Stock) by the written consent of the Majority A Holders. Such waiver shall be in writing and delivered to the Corporation before the Redemption Date applicable thereto and such waiver shall be on the terms and conditions specified therein. (ii) SERIES B PREFERRED STOCK. The Corporation's obligation to redeem all or any portion of any holder's shares of Series B Preferred Stock may be waived in whole or in part by such holder. Such waiver shall be in writing and delivered to the 12

Corporation before the Redemption Date applicable thereto and such waiver shall be on the terms and conditions specified therein. (h) SURRENDER OF CERTIFICATES. Each holder of shares of Preferred Stock to be redeemed shall surrender the certificate(s) representing such shares to the Corporation at the place designated in the Redemption Notice, and thereupon the redemption price for such shares as set forth in this Section B.5 shall be paid to the order of the person whose name appears on such certificate(s) and each surrendered certificate shall be canceled and retired. In the event some but not all of the shares of either series of Preferred Stock represented by a certificate(s) surrendered by a holder are being redeemed, the Corporation shall execute and deliver to or to the order of the holder, at the expense of the Corporation, a new certificate representing the number of shares of such series of Preferred Stock which were not redeemed. (i) DIVIDENDS AFTER REDEMPTION. From and after the Redemption Date, unless there shall have been a default in payment of the Redemption Price therefor, no shares of Preferred Stock subject to redemption shall be entitled to any further dividends pursuant to Section B.2 hereof or any other rights hereunder. (j) NO REISSUANCE OF PREFERRED STOCK. No share or shares of Preferred Stock (of either series) acquired by the Corporation by reason of redemption, purchase or otherwise shall be reissued, and all such shares shall be canceled, retired and eliminated from the shares which the Corporation shall be authorized to issue. The Corporation shall from time to time take such appropriate corporate action as may be necessary to reduce the authorized number of shares of each series Preferred Stock. (k) INSUFFICIENT FUNDS FOR REDEMPTION. If the funds of the Corporation legally available for redemption of Preferred Stock pursuant to Section B.5(a)(i) or Section B.5(c) only on any Redemption Date are insufficient to redeem in full all of the Preferred Stock to be so redeemed on such Redemption Date, the holders of such shares of Preferred Stock to be so redeemed shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the number of shares owned by them if the shares to be so redeemed on such Redemption Date were redeemed in full. If the funds of the Corporation legally available for redemption of Preferred Stock other than pursuant to Section B.5(a)(i) or B.5(c) on any Redemption Date are insufficient to redeem in full all of the Preferred Stock to be so redeemed on such Redemption Date, then until the Series B Redemption Price is paid in full, the holders of shares of Series B Preferred Stock shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the number of shares of Series B Preferred Stock owned by them if the shares of Series B Preferred Stock to be so redeemed on such Redemption Date were redeemed in full; thereafter, the holders of shares of Series A Preferred Stock shall share ratably in any funds legally available for redemption of such shares according to the respective amounts which would be payable with respect to the number of shares of Series A Preferred Stock owned by them if the shares to be so redeemed on such Redemption Date were redeemed in full. The shares of either series of 13

Preferred Stock not redeemed shall remain outstanding and entitled to all rights and preferences provided herein so long as such amounts remain unpaid, notwithstanding Section B.5(i) above. At any time thereafter when additional funds of the Corporation are legally available for the redemption of such shares of Preferred Stock, such funds will be used, immediately, to redeem the balance of such shares, or such portion thereof for which funds are then legally available, on the basis set forth above. 6. RESTRICTIONS AND LIMITATIONS. (a) AMENDMENTS TO CHARTER; CORPORATE ACTION-CONSENT OF ALL PREFERRED STOCK. Notwithstanding anything to the contrary contained herein, the Corporation shall not amend its Articles of Organization without the approval by vote or written consent of the Majority A Holders and the Majority B Holders. In addition, the Corporation will not take any other corporate action without such approval or consent of the Majority A Holders and the Majority B Holders, if such corporate action would: (i) authorize or issue, or obligate the Corporation to authorize or issue, additional shares of Preferred Stock or other class of security senior to or on a parity with the Series A Preferred Stock or Series B Preferred Stock with respect to liquidation preferences, dividend rights, voting rights (other than voting rights of Common Stock with one (1) vote per share), redemption rights; or (ii) merge or consolidate the Corporation with, or sell, assign, lease or otherwise dispose of or voluntarily part with the control of (whether in one transaction or in a series of transactions) all, or substantially all, of its assets or capital stock (whether now owned or hereinafter acquired) or sell, assign or otherwise dispose of (whether in one transaction or in a series of transactions) any asset or group of assets which is material to the business or operations of the Corporation and its subsidiaries, taken as a whole, or permit any subsidiary to do any of the foregoing, except for sales or other dispositions of assets in the ordinary course of business and except that (1) any subsidiary may merge into or consolidate with or transfer assets to any other subsidiary and (2) any subsidiary may merge into or transfer assets to the Corporation; or (iii) acquire or obligate the Corporation to acquire the stock or assets of any entity (other than a wholly-owned subsidiary of the Corporation) for consideration in excess of $10,000 in the aggregate in one or a series of related transactions; PROVIDED, HOWEVER, that investments in short-term U.S. government securities, bank certificates of deposit or other similar investments shall not be deemed a breach of this clause (iii). (b) CORPORATE ACTION-REQUIRED CONSENT OF SERIES B PREFERRED STOCK. In addition to the provisions of subparagraph (a), above, the Corporation will not take any corporate action without the approval of each of the holders of Series B Preferred Stock if such corporate action would: 14

(i) reduce the amount payable to the holders of Series B Preferred Stock upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; or (ii) adversely affect the liquidation preferences, dividend rights, voting rights, redemption rights, conversion rights or other rights of the holders of Series B Preferred Stock. (c) CORPORATE ACTION-REQUIRED CONSENT OF SERIES A PREFERRED STOCK. In addition, the Corporation will not take any corporate action without the approval of the Majority A Holders if such corporate action would: (i) reduce the amount payable to the holders of Series A Preferred upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation; or (ii) adversely affect the liquidation preferences, dividend rights, voting rights or redemption rights of the holders of Series A Preferred Stock. 7. NO IMPAIRMENT. The Corporation will not, by amendment of its Articles of Organization or through any reorganization, transfer of capital stock or assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of either series of Preferred Stock set forth herein, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holders of the Preferred Stock against impairment. Without limiting the generality of the foregoing the Corporation will not transfer all or substantially all of its properties and assets to any other person (corporate or otherwise), or consolidate with or merge into any other person or permit any such person to consolidate with or merge into the Corporation (if the Corporation is not the surviving person), unless such transaction is effected in accordance with Section B.6 and such other person shall expressly assume in writing and will be bound by all the terms of each series of Preferred Stock set forth herein. 8. NOTICES OF RECORD DATE. In the event of (a) any taking by the Corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of capital stock of any class or any other securities or property, or to receive any other right, or (b) any capital reorganization of the Corporation, any reclassification or recapitalization of the capital stock of the Corporation, any merger or consolidation of the Corporation, or any transfer of all or substantially all of the assets of the Corporation or any subsidiary of the Corporation or any material and substantial asset or group of assets of the 15

Corporation or of any subsidiary of the Corporation to any other company, or any other entity or person, or (c) any voluntary or involuntary dissolution, liquidation or winding up of the Corporation, then and in each such event the Corporation shall mail or cause to be mailed to each holder of Series A Preferred Stock and each holder of Series B Preferred Stock, a notice specifying (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or right and a description of such dividend, distribution or right, (ii) the date on which any such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding up is expected to become effective, and (iii) the time, if any, that is to be fixed, as to when the holders of record of Common Stock (or other securities) shall be entitled to exchange their shares of Common Stock (or other securities) for securities or other property deliverable upon such reorganization, reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding up. Such notice shall be delivered by hand, sent by reputable overnight courier service or electronic facsimile transmission (return receipt requested or mailed by first class mail, postage prepaid, at least thirty (30) days prior to the date specified in such notice on which such action is to be taken. 9. CONVERSION RIGHTS. The holders of Series B Preferred Stock shall have conversion rights as follows: (a) RIGHT TO CONVERT. Subject to and in compliance with the provisions of this Section B.9, any shares of Series B Preferred Stock may be converted at any time and from time to time into fully-paid and non-assessable shares of Common Stock. The number of shares of Common Stock to which each share of the Series B Preferred Stock shall be converted shall be computed by multiplying the number of shares of Series B Preferred Stock to be converted by $20.6185567 (which amount shall be subject to adjustment upon any subdivision of shares of Series B Preferred Stock or any issuance of additional shares of Series B Preferred Stock as a dividend or other distribution on outstanding Series B Preferred Stock) and dividing the result by the applicable Conversion Price then in effect. The initial Conversion Price shall be $20.6185567, subject to adjustment from time to time pursuant to this Section B.9. (b) VOLUNTARY CONVERSION. (i) At any time and from time to time, upon the written election of any holder of Series B Preferred Stock, all or any part of the shares of Series B Preferred Stock of such holder may be converted into a number of shares of Common Stock calculated in accordance with Section B.9(a) above. 16

(ii) At any time, upon the written election of holders of at least seventy percent (70%) in interest of the then outstanding shares of Series B Preferred Stock, all of the shares of Series B Preferred Stock then outstanding shall be converted into a number of shares of Common Stock calculated in accordance with Section B.9(a) above. (c) AUTOMATIC CONVERSION. Each share of Series B Preferred Stock outstanding shall automatically be converted into the number of shares of Common Stock into which such shares are convertible pursuant to the formula set forth in Section B.9(a) above at the then effective Conversion Price immediately upon the closing of an underwritten public offering (a "Qualified Public Offering") pursuant to an effective registration statement under the Securities Act of 1933, as amended, covering the offer and sale of Common Stock of the Corporation of which the aggregate net proceeds attributable to sales for the account of the Corporation exceed $15,000,000 at a per share price to the public (as set forth in the final prospectus in connection with such public offering) equal to at least $41.2371134 (which amount shall be subject to Equitable Adjustment). (d) CONVERSION PROCEDURES. (i) Upon the occurrence of an event specified in subparagraphs (b)(ii) or (c) above, the outstanding shares of Series B Preferred Stock shall be converted automatically without any further action by the holders of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent; PROVIDED, HOWEVER, that the Corporation shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion unless certificates evidencing such shares of the Series B Preferred Stock being converted are delivered to the Corporation or any transfer agent, or the holder notifies the Corporation or any transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement reasonably satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection therewith. (ii) Upon surrender at the principal executive office of the Corporation or the offices of the transfer agent for the Series B Preferred Stock or such office or offices in the continental United States of an agent for conversion as may from time to time be designated by notice to the holders of the Series B Preferred Stock by the Corporation, of either (x) the certificate or certificates representing the Series B Preferred Stock being converted, duly assigned or endorsed for transfer to the Corporation (or accompanied by duly executed stock powers relating thereto) or (y) an affidavit certifying that such certificate(s) has been lost, stolen or destroyed (along with an agreement reasonably satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection therewith), in either case accompanied by written notice of conversion and the payment to the Corporation of a sum sufficient to cover any tax or governmental charge imposed with respect to the issuance of Common Stock in a name other than that of the holder of the Series B Preferred Stock being converted, the Corporation shall issue and send by hand delivery, by courier or by first class mail (postage prepaid) to the holder thereof or to such holder's designee, at the address designated by such holder, a certificate or certificates for the number 17

of shares of Common Stock to which such holder shall be entitled upon conversion, and the Corporation shall pay to the holder of the Series B Preferred Stock being converted an amount equal to all accrued and unpaid dividends thereon, whether or not earned or declared, up to and including the effective date of conversion. (e) EFFECTIVE DATE OF CONVERSION. The issuance by the Corporation of shares of Common Stock upon a conversion of Series B Preferred Stock into shares of Common Stock shall be effective as to any holder upon the earliest of the date that holders of at least seventy percent (70%) of the then outstanding shares of Series B Preferred Stock or such holder of Series B Preferred Stock shall have elected conversion pursuant to Section B.9(b) hereof by notice to the Corporation to such effect or immediately prior to the closing of a Qualified Public Offering, as applicable. On and after the effective date of conversion, the person or persons entitled to receive the Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock. (f) FRACTIONAL SHARES. The Corporation shall not be obligated to deliver to holders of Series B Preferred Stock any fractional share of Common Stock issuable upon any conversion of such Series B Preferred Stock, but in lieu thereof may make a cash payment in respect thereof in any manner permitted by law. (g) RESERVATION OF COMMON STOCK. The Corporation shall at all times reserve and keep available out of its authorized and unissued Common Stock, solely for issuance upon the conversion of Series B Preferred Stock as herein provided, free from any preemptive rights or other obligations, such number of shares of Common Stock as shall from time to time be issuable upon the conversion of all the Series B Preferred Stock then outstanding, provided that the shares of Common Stock so reserved shall not be reduced or affected in any manner whatsoever so long as any shares of Series B Preferred Stock are outstanding. The Corporation shall prepare and shall use its best efforts to obtain and keep in force such governmental or regulatory permits or other authorizations as may be required by law, and shall comply with all requirements as to registration, qualification or listing of the Common Stock, in order to enable the Corporation lawfully to issue and deliver to each holder of record of Series B Preferred Stock such number of shares of its Common Stock as shall from time to time be sufficient to effect the conversion of all Series B Preferred Stock then outstanding and convertible into shares of Common Stock. (h) ADJUSTMENTS TO CONVERSION PRICE. The Conversion Price in effect from time to time shall be subject to adjustment, regardless of whether any shares of Series B Preferred Stock are then issued and outstanding, as follows: (i) STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. Upon the issuance of additional shares of Common Stock as a dividend or other distribution on outstanding Common Stock or other capital stock, the subdivision of outstanding shares of Common Stock into a greater number of shares of Common Stock, or the combination of outstanding shares of Common Stock into a smaller number of shares of the Common Stock, 18

the Conversion Price shall, simultaneously with the happening of such dividend, subdivision or split be adjusted by multiplying the then effective Conversion Price by a fraction, the NUMERATOR of which shall be the number of shares of Common Stock outstanding immediately prior to such event and the DENOMINATOR of which shall be the number of shares of Common Stock outstanding immediately after such event. An adjustment made pursuant to this Section B.9(h)(i) shall be given effect, upon payment of such a dividend or distribution, as of the record date for the determination of stockholders entitled to receive such dividend or distribution (on a retroactive basis) and in the case of a subdivision or combination shall become effective immediately as of the effective date thereof. (ii) SALE OF COMMON STOCK. In the event the Corporation shall at any time, or from time to time, issue, sell or exchange any shares of Common Stock (including shares held in the Corporation's treasury but excluding (i) up to 206,620 shares of Common Stock (as appropriately adjusted for stock splits, stock dividends and the like) issued or to be issued to officers, directors, employees, consultants or agents of the Corporation or upon the exercise of options or other rights issued or to be issued to such officers, directors, employees, consultants or agents pursuant to the Corporation's 1996 Stock Option and Grant Plan, (ii) up to 431,756 shares of Common Stock (as appropriately adjusted for stock splits, stock dividends and the like) issuable upon exercise or conversion of the Warrants and (iii) the shares of Common Stock issuable upon conversion of the Series B Preferred Stock (collectively, (the "Excluded Shares")), for a consideration per share less than the Conversion Price in effect immediately prior to the issuance, sale or exchange of such shares, then, and thereafter successively upon each such issuance, sale or exchange, the Conversion Price in effect immediately prior to the issuance, sale or exchange of such shares shall forthwith be reduced to an amount determined by multiplying such Conversion Price by a fraction: (1) the NUMERATOR of which shall be (i) the number of shares of Common Stock outstanding immediately prior to the issuance of such additional shares of Common Stock (excluding treasury shares but including all shares of Common Stock issuable upon conversion, exchange or exercise of any outstanding Preferred Stock, options, warrants, rights or other convertible or exchangeable securities), plus (ii) the number of shares of Common Stock which the net aggregate consideration received by the Corporation for the total number of such additional shares of Common Stock so issued would purchase at the Conversion Price (prior to adjustment), and (2) the DENOMINATOR of which shall be (i) the number of shares of Common Stock outstanding immediately prior to the issuance of such additional shares of Common Stock (excluding treasury shares but including all shares of Common Stock issuable upon conversion or exercise of any outstanding Preferred Stock, options, warrants, rights or other convertible or exchangeable securities), plus (ii) the number of such additional shares of Common Stock so issued. 19

(iii) SALE OF OPTIONS, RIGHTS OR CONVERTIBLE SECURITIES. In the event the Corporation shall at any time or from time to time, issue options, warrants or rights to subscribe for shares of Common Stock (other than any options for Excluded Shares), or issue any securities convertible into or exchangeable for shares of Common Stock (or any options, warrants, or rights to subscribe for such convertible or exchangeable securities), for a consideration per share (determined by dividing the Net Aggregate Consideration (as determined below) by the aggregate number of shares of Common Stock that would be issued if all such options, warrants, rights or convertible or exchangeable securities were exercised, converted or exchanged to the fullest extent permitted by their terms) less than the Conversion Price in effect immediately prior to the issuance of such options or rights or convertible or exchangeable securities, the Conversion Price in effect immediately prior to the issuance of such options, warrants or rights or convertible or exchangeable securities shall forthwith be reduced to an amount determined by multiplying such Conversion Price by a fraction: (1) the NUMERATOR of which shall be (i) the number of shares of Common Stock outstanding immediately prior to the issuance of such options, rights or convertible securities (excluding treasury shares but including all shares of Common Stock issuable upon conversion or exercise of any outstanding Preferred Stock, options, warrants, rights or other convertible or exchangeable securities), plus (ii) the number of shares of Common Stock which the net aggregate amount of consideration received by the Corporation for the issuance of such options, warrants, rights or other convertible or exchangeable securities, plus the minimum amount set forth in the terms of such security as payable to the Corporation upon the exercise, exchange or conversion thereof (the "Net Aggregate Consideration") would purchase at the Conversion Price (prior to adjustment), and (2) the DENOMINATOR of which shall be (i) the number of shares of Common Stock outstanding immediately prior to the issuance of such options, warrants, rights or convertible or exchangeable securities (excluding treasury shares but including all shares of Common Stock issuable upon conversion, exchange or exercise of any outstanding Preferred Stock, options, warrants, rights or other convertible or exchangeable securities), plus (ii) the aggregate number of shares of Common Stock that would be issued if all such options, warrants, rights or other convertible or exchangeable securities were exercised, exchanged or converted. (iv) EXPIRATION OR CHANGE IN PRICE OR NUMBER OF SHARES. If the consideration per share and/or the number of shares issuable provided for in any options or rights to subscribe for shares of Common Stock or any securities exchangeable for or convertible into shares of Common Stock (other than options, warrants or convertible securities for Excluded Shares), changes at any time (other than in connection with a transaction provided for elsewhere in this Section B.9 and for which adjustment has been made pursuant to this Section B.9), the Conversion Price in effect at the time of such change shall be 20

readjusted to the Conversion Price which would have been in effect at such time had such options, rights or exchangeable or convertible securities provided for such changed consideration and/or changed number of shares issuable per share (determined as provided in Section B.9(h)(iii) hereof), at the time initially granted, issued or sold (subject to any intervening adjustments); PROVIDED, that such adjustment of the Conversion Price will be made only as and to the extent that the Conversion Price effective upon such adjustment remains less than or equal to the Conversion Price that would be in effect if such options, rights or securities had not been issued. No adjustment of the Conversion Price shall be made under this Section B.9 upon the issuance of any shares of Common Stock which are issued pursuant to the exercise of any warrants, options or other subscription or purchase rights or pursuant to the exercise of any conversion or exchange rights in any convertible securities if an adjustment shall previously have been made upon the issuance of such warrants, options or other rights. Any adjustment of the Conversion Price shall be disregarded and rescinded if (but only to the extent), as, and when the rights to acquire shares of Common Stock upon exercise or conversion of the warrants, options, rights or convertible securities which gave rise to such adjustment expire or are canceled without having been exercised, so that the Conversion Price effective immediately upon such cancellation or expiration shall be equal to the Conversion Price in effect at the time of the issuance of the expired or canceled warrants, options, rights or convertible securities (subject to any intervening adjustments), with such additional adjustments as would have been made to that Conversion Price had the expired or canceled warrants, options, rights or convertible securities not been issued. (i) MERGERS AND OTHER REORGANIZATIONS. If at any time or from time to time there shall be a capital reorganization of the Common Stock (other than a subdivision, combination, reclassification or exchange of shares provided for elsewhere in this Section B.9) or a merger or consolidation of the Corporation with or into another corporation or the sale of all or substantially all of the Corporation's properties and assets to any other person, then, as a part of and as a condition to the effectiveness of such reorganization, merger, consolidation or sale, lawful and adequate provision shall be made so that the holders of the Series B Preferred Stock shall thereafter be entitled to receive upon conversion of the Series B Preferred Stock the kind and amount of shares of stock or other securities or property resulting from such merger or consolidation or sale, to which a holder of Common Stock deliverable upon such conversion would have been entitled on such capital reorganization, merger, consolidation, or sale. In any such case, appropriate provisions shall be made with respect to the rights of the holders of the Series B Preferred Stock after the reorganization, merger, consolidation or sale to the end that the provisions of this Section B.9 (including without limitation provisions for adjustment of the Conversion Price and the number of shares purchasable upon conversion of the Series B Preferred Stock) shall thereafter be applicable, as nearly as may be, with respect to any shares of stock, securities or assets to be deliverable thereafter upon the conversion of the Series B Preferred Stock. Upon the occurrence of a Liquidation Event (as defined in Section B.3(b)), each holder of Series B Preferred Stock shall have the option, upon written election of such holder, of 21

having its shares of Series B Preferred Stock treated under either this Section B.9(i) or Section B.5(a)(iv) hereof. (j) OTHER ADJUSTMENTS. In the event the Corporation shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation other than shares of Common Stock, then and in each such event lawful and adequate provision shall be made so that the holders of Series B Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the number of securities of the Corporation which they would have received had their Series B Preferred Stock been converted into Common Stock on the date of such event and had they thereafter, during the period from the date of such event to and including the effective date of the conversion, retained such securities receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under this Section B.9 as applied to such distributed securities. If the Common Stock issuable upon the conversion of the Series B Preferred Stock shall be changed into the same or different number of shares of any class or classes of stock, whether by reclassification or otherwise (other than a subdivision or combination of shares or stock dividend provided for above, or a reorganization, merger, consolidation or sale of assets provided for elsewhere in this Section B.9), then and in each such event the holder of each share of Series B Preferred Stock shall have the right thereafter to convert such share of Series B Preferred Stock into the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification or other change, by holders of the number of shares of Common Stock into which such shares of Series B Preferred Stock might have been converted immediately prior to such reorganization, reclassification or change, all subject to further adjustment as provided herein. (k) NOTICES. In each case of an adjustment or readjustment of the Conversion Price, the Corporation will furnish each holder of Series B Preferred Stock with a certificate, prepared by the Chief Financial Officer of the Corporation, showing such adjustment or readjustment, and stating in detail the facts upon which such adjustment or readjustment is based. In the event of any dispute between the Corporation and holders representing at least 10% of the outstanding Series B Preferred Stock regarding such adjustment or readjustment, the Corporation and such holders of the Series B Preferred Stock shall first use their best efforts to resolve such dispute among themselves or to agree upon the selection of the firm of independent certified public accountants of recognized standing (each, an "Independent Accounting Firm"), to make a final and binding determination of the adjustment or readjustment. If the parties are unable to resolve the dispute or to agree upon an Independent Accounting Firm within 30 calendar days after the commencement of efforts to resolve the dispute, a majority-in-interest of such holders, on one hand, and the Corporation, on the other hand, shall each select an Independent Accounting Firm within 30 days after the conclusion of such initial 30 day period. Within 10 days after such selection, each such Independent Accounting Firm shall select a third Independent Accounting Firm to make a final and binding 22

determination of such adjustment or readjustment. Each of the Corporation, on the one hand, and such holders of the Series B Preferred Stock, on the other hand, shall be responsible for the fees and expenses of the Independent Accounting Firm selected by such party(ies). The determination of the Independent Accounting Firm selected by agreement of the parties or selected by their respective Independent Accounting Firms shall be final and binding on the Corporation and the holders and the expenses of such Independent Accounting Firm shall be borne one-half by the Corporation and one-half by such holders, pro rata in proportion to the number of shares of Series B Preferred Stock owned by each such holder. (l) OTHER DILUTIVE EVENTS. If any other transaction or event (other than those explicitly referred to in this Section B.9) shall occur as to which the other provisions of this Section B.9 are not strictly applicable but the failure to make any adjustment to the Conversion Price or any of the other terms of the Series B Preferred Stock would not fairly protect the conversion or other rights of the holders of the Series B Preferred Stock set forth herein in accordance with the essential intent and principles hereof, then, and as a condition to the consummation of any such transaction or event, and in each such case, the Corporation and the Majority B Holders shall appoint an Independent Accounting Firm (in the manner provided in the preceding subparagraph (k)) which shall give its opinion as to the adjustment, if any, on a basis consistent with the essential intent and principle established in this Section B.9(l), necessary to preserve, without dilution, the rights of the holders of the Series B Preferred Stock. 10. DISPUTES AS TO FAIR MARKET VALUE. In the event of any dispute between the Corporation and any holder or holders representing at least 10% of the outstanding shares of any class of Preferred Stock regarding the determination of fair market value of any property or security, the Corporation and such holders of such class of Preferred Stock shall first use their best efforts to resolve such dispute among themselves or to agree upon the selection of an independent, non-affiliated appraiser of recognized standing with at least five (5) years of experience in the relevant industry (each an "Independent Appraiser") to make a final and binding determination of the fair market value of such property or security (without any discount for lack of control, if applicable). If the parties are unable to resolve the dispute or to agree upon an Independent Appraiser within thirty (30) calendar days after the commencement of efforts to resolve the dispute, a majority-in-interest of such holders of such class of Preferred Stock and the Corporation each shall select an Independent Appraiser within thirty (30) days after the conclusion of such initial thirty (30) day period. Within ten (10) days after such selection, such Independent Appraisers shall select a third non-affiliated appraiser of recognized standing with at least five (5) years experience in the relevant industry (the "Third Appraiser") to make a final and binding determination of the fair market value of such property or security (without any discount for lack of control, if applicable). Each of the Corporation, on the one hand, and such holders of the shares of such class of Preferred Stock, on the other hand, shall be responsible for the fees and expenses of the Independent Appraiser selected by such party(ies). The determination of the Independent Appraiser selected by agreement of the parties or the Third Appraiser selected as provided above (as the case may be) shall be final and binding on the Corporation and the holders, and the expenses of such 23

agreed upon Independent Appraiser or Third Appraiser (as the case may be) shall be borne one-half by the Corporation and one-half by such holders, pro-rata in proportion to the number of shares of such class of Preferred Stock owned by each such holder. C. UNDESIGNATED PREFERRED STOCK The Board of Directors or any authorized committee thereof is expressly authorized, to the fullest extent permitted by law, to provide for the issuance of the shares of Undesignated Preferred Stock in one or more series of such stock, and by filing a certificate pursuant to applicable law of the State of Delaware, to establish or change from time to time the number of shares of each such series, and to fix the designations, powers, including voting powers, full or limited, or no voting powers, preferences and the relative, participating, optional or other special rights of the shares of each series and any qualifications, limitations and restrictions thereof. ARTICLE V STOCKHOLDER ACTION 1. ACTION WITHOUT MEETING. Except as otherwise provided herein, any action required or permitted to be taken by the stockholders of the Corporation at any annual or special meeting of stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders and may not be taken or effected by a written consent of stockholders in lieu thereof. 2. SPECIAL MEETINGS. Except as otherwise required by statute and subject to the rights, if any, of the holders of any series of Undesignated Preferred Stock, special meetings of the stockholders of the Corporation may be called only by the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the Directors then in office. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation. ARTICLE VI DIRECTORS 1. GENERAL. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors except as otherwise provided herein or required by law. 2. ELECTION OF DIRECTORS.

3. NUMBER OF DIRECTORS; TERM OF OFFICE. The number of Directors of the Corporation shall be fixed solely and exclusively by resolution duly adopted from time to time by the Board of Directors. The Directors, other than those who may be elected by the holders of any series or class of Preferred Stock, shall be classified, with respect to the term for which they severally hold office, into three classes, as nearly equal in number as reasonably possible. The initial Class I Directors of the Corporation shall be Christopher W. Dick, Robert Dishman and Richard C. Klaffky, Jr.; the initial Class II Directors of the Corporation shall be David Green and John F. Kennedy; and the initial Class III Directors of the Corporation shall be Chane Graziano and Earl R. Lewis. The initial Class I Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2001, the initial Class II Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2002, and the initial Class III Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2003. At each annual meeting of stockholders, Directors elected to succeed those Directors whose terms expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election. Notwithstanding the foregoing, the Directors elected to each class shall hold office until their successors are duly elected and qualified or until their earlier resignation or removal. Notwithstanding the foregoing, whenever, pursuant to the provisions of Article IV of this Certificate, the holders of any one or more series or class of Preferred Stock shall have the right, voting separately as a series or together with holders of other such series, to elect Directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of this Certificate and any certificate of designations applicable thereto. 4. VACANCIES. Subject to the rights, if any, of the holders of any series or class of Preferred Stock to elect Directors and to fill vacancies in the Board of Directors relating thereto, any and all vacancies in the Board of Directors, however occurring, including, without limitation, by reason of an increase in size of the Board of Directors, or the death, resignation, disqualification or removal of a Director, shall be filled solely and exclusively by the affirmative vote of a majority of the remaining Directors then in office, even if less than a quorum of the Board of Directors, and not by the stockholders. Any Director appointed in accordance with the preceding sentence shall hold office for the remainder of the full term of the class of Directors in which the new directorship was created or the vacancy occurred and until such Director's successor shall have been duly elected and qualified or until his or her earlier resignation or removal. Subject to the rights, if any, of the holders of any series or class of Preferred Stock to elect Directors, when the number of Directors is increased or decreased, the Board of Directors shall, subject to Article VI.3 hereof, determine the class or classes to which the increased or decreased number of Directors shall be apportioned; PROVIDED, HOWEVER, that no decrease in the number of Directors shall shorten the term of any incumbent Director. 5. REMOVAL. Subject to the rights, if any, of any series or class of Preferred Stock to elect Directors and to remove any Director whom the holders of any such stock have the 25

right to elect, any Director (including persons elected by Directors to fill vacancies in the Board of Directors) may be removed from office (i) only with cause and (ii) only by the affirmative vote of the holders of 75% or more of the shares then entitled to vote at an election of Directors. At least forty-five (45) days prior to any meeting of stockholders at which it is proposed that any Director be removed from office, written notice of such proposed removal and the alleged grounds thereof shall be sent to the Director whose removal will be considered at the meeting. ARTICLE VII LIMITATION OF LIABILITY A Director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a Director, except for liability (a) for any breach of the Director's duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL or (d) for any transaction from which the Director derived an improper personal benefit. If the DGCL is amended after the effective date of this Certificate to authorize corporate action further eliminating or limiting the personal liability of Directors, then the liability of a Director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. Any repeal or modification of this Article VII by either of (i) the stockholders of the Corporation or (ii) an amendment to the DGCL, shall not adversely affect any right or protection existing at the time of such repeal or modification with respect to any acts or omissions occurring before such repeal or modification of a person serving as a Director at the time of such repeal or modification. ARTICLE VIII AMENDMENT OF BY-LAWS 1. AMENDMENT BY DIRECTORS. Except as otherwise provided by law, the By-laws of the Corporation may be amended or repealed by the Board of Directors by the affirmative vote of a majority of the Directors then in office. 2. AMENDMENT BY STOCKHOLDERS.

of the shares present in person or represented by proxy at such meeting and entitled to vote on such amendment or repeal, voting together as a single class. ARTICLE IX AMENDMENT OF CERTIFICATE OF INCORPORATION The Corporation reserves the right to amend or repeal this Certificate in the manner now or hereafter prescribed by statute and this Certificate, and all rights conferred upon stockholders herein are granted subject to this reservation. Whenever any vote of the holders of voting stock is required to amend or repeal any provision of this Certificate, and in addition to any other vote of holders of voting stock that is required by this Certificate or by law, such amendment or repeal shall require the affirmative vote of the majority of the outstanding shares entitled to vote on such amendment or repeal, and the affirmative vote of the majority of the outstanding shares of each class entitled to vote thereon as a class, at a duly constituted meeting of stockholders called expressly for such purpose; PROVIDED, HOWEVER, that the affirmative vote of not less than 75% of the outstanding shares entitled to vote on such amendment or repeal, and the affirmative vote of not less than 75% of the outstanding shares of each class entitled to vote thereon as a class, shall be required to amend or repeal any provision of Article V, Article VI, Article VII or Article IX of this Certificate.

If no Annual Meeting has been held for a period of thirteen months after the Corporation's last Annual Meeting, a special meeting in lieu thereof may be held, and such special meeting shall have, for the purposes of these By-laws or otherwise, all the force and effect of an Annual Meeting. Any and all references hereafter in these By-laws to an Annual Meeting or Annual Meetings also shall be deemed to refer to any special meeting(s) in lieu thereof. SECTION 2. NOTICE OF STOCKHOLDER BUSINESS AND NOMINATIONS. (a) ANNUAL MEETINGS OF STOCKHOLDERS. (1) Nominations of persons for election to the Board of Directors of the Corporation and the proposal of business to be considered by the stockholders may be made at an Annual Meeting (a) pursuant to the Corporation's notice of meeting, (b) by or at the direction of the Board of Directors or (c) by any stockholder of the Corporation who was a stockholder of record at the time of giving of notice provided for in this By-law, who is entitled to vote at the meeting, who is present (in person or by proxy) at the meeting and who complies with the notice procedures set forth in this By-law. In addition to the other requirements set forth in this By-law, for any proposal of business to be considered at an Annual Meeting, it must be a proper subject for action by stockholders of the Corporation under Delaware law. (2) For nominations or other business to be properly brought before an Annual Meeting by a stockholder pursuant to clause (c) of paragraph (a)(1) of this By-law, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a stockholder's notice shall be delivered to the Secretary at the principal executive offices of the Corporation not later than the close of

business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year's Annual Meeting; provided, however, that in the event that the date of the Annual Meeting is advanced by more than 30 days before or delayed by more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to such Annual Meeting and not later than the close of business on the later of the 90th day prior to such Annual Meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. Notwithstanding anything to the contrary provided herein, for the first Annual Meeting following the initial public offering of common stock of the Corporation, a stockholder's notice shall be timely if delivered to the Secretary at the principal executive offices of the Corporation not later than the close of business on the later of the 90th day prior to the scheduled date of such Annual Meeting or the 10th day following the day on which public announcement of the date of such Annual Meeting is first made or sent by the Corporation. Such stockholder's notice shall set forth (a) as to each person whom the stockholder proposes to nominate for election or reelection as a director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the "Exchange Act") and Rule 14a-11 thereunder (including such person's written consent to being named in the proxy statement as a nominee and to serving as a director if elected); (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting, any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made, and the names and addresses of other stockholders known by the stockholder proposing such business to support such proposal, and the class and number of shares of the Corporation's capital stock beneficially owned by such other stockholders; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the Corporation's books, and of such beneficial owner, and (ii) the class and number of shares of the Corporation which are owned beneficially and of record by such stockholder and such beneficial owner. (3) Notwithstanding anything in the second sentence of paragraph (a)(2) of this By-law to the contrary, in the event that the number of directors to be elected to the Board of Directors of the Corporation is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the Corporation at least 85 days prior to the first anniversary of the preceding year's Annual Meeting, a stockholder's notice required by this By-law shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal 2

executive offices of the Corporation not later than the close of business on the 10th day following the day on which such public announcement is first made by the Corporation. (b) GENERAL. (1) Only such persons who are nominated in accordance with the provisions of this By-law shall be eligible for election and to serve as directors and only such business shall be conducted at an Annual Meeting as shall have been brought before the meeting in accordance with the provisions of this By-law. The Board of Directors or a designated committee thereof shall have the power to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the provisions of this By-law. If neither the Board of Directors nor such designated committee makes a determination as to whether any stockholder proposal or nomination was made in accordance with the provisions of this By-law, the presiding officer of the Annual Meeting shall have the power and duty to determine whether the stockholder proposal or nomination was made in accordance with the provisions of this By-law. If the Board of Directors or a designated committee thereof or the presiding officer, as applicable, determines that any stockholder proposal or nomination was not made in accordance with the provisions of this By-law, such proposal or nomination shall be disregarded and shall not be presented for action at the Annual Meeting. (2) For purposes of this By-law, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act. (3) Notwithstanding the foregoing provisions of this By-law, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this By-law. Nothing in this By-law shall be deemed to affect any rights of (i) stockholders to request inclusion of proposals in the Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act or (ii) the holders of any series of Undesignated Preferred Stock to elect directors under specified circumstances. SECTION 3. SPECIAL MEETINGS. Except as otherwise required by statute and subject to the rights, if any, of the holders of any series of Undesignated Preferred Stock, special meetings of the stockholders of the Corporation may be called only by the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the Directors then in office. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation. 3

SECTION 4. NOTICE OF MEETINGS; ADJOURNMENTS. A written notice of each Annual Meeting stating the hour, date and place of such Annual Meeting shall be given not less than 10 days nor more than 60 days before the Annual Meeting, to each stockholder entitled to vote thereat by delivering such notice to such stockholder or by mailing it, postage prepaid, addressed to such stockholder at the address of such stockholder as it appears on the Corporation's stock transfer books. Such notice shall be deemed to be given when hand delivered to such address or deposited in the mail so addressed, with postage prepaid. Notice of all special meetings of stockholders shall be given in the same manner as provided for Annual Meetings, except that the written notice of all special meetings shall state the purpose or purposes for which the meeting has been called. Notice of an Annual Meeting or special meeting of stockholders need not be given to a stockholder if a written waiver of notice is signed before or after such meeting by such stockholder or if such stockholder attends such meeting, unless such attendance was for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting was not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any Annual Meeting or special meeting of stockholders need be specified in any written waiver of notice. The Board of Directors may postpone and reschedule any previously scheduled Annual Meeting or special meeting of stockholders and any record date with respect thereto, regardless of whether any notice or public disclosure with respect to any such meeting has been sent or made pursuant to Section 2 of this Article I of these By-laws or otherwise. In no event shall the public announcement of an adjournment, postponement or rescheduling of any previously scheduled meeting of stockholders commence a new time period for the giving of a stockholder's notice under Section 2 of this Article I of these By-laws. When any meeting is convened, the presiding officer may adjourn the meeting if (a) no quorum is present for the transaction of business, (b) the Board of Directors determines that adjournment is necessary or appropriate to enable the stockholders to consider fully information which the Board of Directors determines has not been made sufficiently or timely available to stockholders, or (c) the Board of Directors determines that adjournment is otherwise in the best interests of the Corporation. When any Annual Meeting or special meeting of stockholders is adjourned to another hour, date or place, notice need not be given of the adjourned meeting other than an announcement at the meeting at which the adjournment is taken of the hour, date and place to which the meeting is adjourned; provided, however, that if the adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting shall be given to each stockholder of record entitled to vote thereat and each stockholder who, by law or under the Certificate of Incorporation of the Corporation (as the same may hereafter be amended and/or restated, the "Certificate") or these By-laws, is entitled to such notice. 4

SECTION 5. QUORUM. A majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders. If less than a quorum is present at a meeting, the holders of voting stock representing a majority of the voting power present at the meeting or the presiding officer may adjourn the meeting from time to time, and the meeting may be held as adjourned without further notice, except as provided in Section 5 of this Article I. At such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally noticed. The stockholders present at a duly constituted meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. SECTION 6. VOTING AND PROXIES. Stockholders shall have one vote for each share of stock entitled to vote owned by them of record according to the stock ledger of the Corporation, unless otherwise provided by law or by the Certificate. Stockholders may vote either (i) in person, (ii) by written proxy or (iii) by a transmission permitted by Section 212(c) of the Delaware General Corporation Law ("DGCL"). Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission permitted by Section212(c) of the DGCL may be substituted for or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission. Proxies shall be filed in accordance with the procedures established for the meeting of stockholders. Except as otherwise limited therein or as otherwise provided by law, proxies authorizing a person to vote at a specific meeting shall entitle the persons authorized thereby to vote at any adjournment of such meeting, but they shall not be valid after final adjournment of such meeting. A proxy with respect to stock held in the name of two or more persons shall be valid if executed by or on behalf of any one of them unless at or prior to the exercise of the proxy the Corporation receives a specific written notice to the contrary from any one of them. SECTION 7. ACTION AT MEETING. When a quorum is present at any meeting of stockholders, any matter before any such meeting (other than an election of a director or directors) shall be decided by a majority of the votes properly cast for and against such matter, except where a larger vote is required by law, by the Certificate or by these By-laws. Any election of directors by stockholders shall be determined by a plurality of the votes properly cast on the election of directors. The Corporation shall not directly or indirectly vote any shares of its own stock; provided, however, that the Corporation may vote shares which it holds in a fiduciary capacity to the extent permitted by law. SECTION 8. STOCKHOLDER LISTS. The Secretary or an Assistant Secretary (or the Corporation's transfer agent or other person authorized by these By-laws or by law) shall prepare and make, at least 10 days before every Annual Meeting or special meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares 5

registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the hour, date and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. SECTION 9. PRESIDING OFFICER. The Chairman of the Board, if one is elected, or if not elected or in his or her absence, the President, shall preside at all Annual Meetings or special meetings of stockholders and shall have the power, among other things, to adjourn such meeting at any time and from time to time, subject to Sections 5 and 6 of this Article I. The order of business and all other matters of procedure at any meeting of the stockholders shall be determined by the presiding officer. SECTION 10. INSPECTORS OF ELECTIONS. The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the presiding officer shall appoint one or more inspectors to act at the meeting. Any inspector may, but need not, be an officer, employee or agent of the Corporation. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspectors shall perform such duties as are required by the DGCL, including the counting of all votes and ballots. The inspectors may appoint or retain other persons or entities to assist the inspectors in the performance of the duties of the inspectors. The presiding officer may review all determinations made by the inspectors, and in so doing the presiding officer shall be entitled to exercise his or her sole judgment and discretion and he or she shall not be bound by any determinations made by the inspectors. All determinations by the inspectors and, if applicable, the presiding officer, shall be subject to further review by any court of competent jurisdiction. ARTICLE II DIRECTORS SECTION 1. POWERS.

Any action required or permitted to be taken at any meeting of the Board of Directors may be taken without a meeting if all members of the Board of Directors consent thereto in writing.

MANNER OF PARTICIPATION. Directors may participate in meetings of the Board of Directors by means of conference telephone or similar communications equipment by means of which all directors participating in the meeting can hear each other, and participation in a meeting in accordance herewith shall constitute presence in person at such meeting for purposes of these By-laws.

Other officers may be elected by the Board of Directors at such regular annual meeting of the Board of Directors or at any other regular or special meeting. SECTION 3. QUALIFICATION.

Any officer may be required by the Board of Directors to give bond for the faithful performance of his or her duties in such amount and with such sureties as the Board of Directors may determine.

SECTION 13. TREASURER AND ASSISTANT TREASURERS.

The Treasurer shall have custody of all funds, securities, and valuable documents of the Corporation. He or she shall have such other duties and powers as may be designated from time to time by the Board of Directors or the Chief Executive Officer. Any Assistant Treasurer shall have such powers and perform such duties as the Board of Directors or the Chief Executive Officer may from time to time designate. 10

In his or her absence from any such meeting, a temporary secretary chosen at the meeting shall record the proceedings thereof. The Secretary shall have charge of the stock ledger (which may, however, be kept by any transfer or other agent of the Corporation). The Secretary shall have custody of the seal of the Corporation, and the Secretary, or an Assistant Secretary, shall have authority to affix it to any instrument requiring it, and, when so affixed, the seal may be attested by his or her signature or that of an Assistant Secretary. The Secretary shall have such other duties and powers as may be designated from time to time by the Board of Directors or the Chief Executive Officer. In the absence of the Secretary, any Assistant Secretary may perform his or her duties and responsibilities. Any Assistant Secretary shall have such powers and perform such duties as the Board of Directors or the Chief Executive Officer may from time to time designate. SECTION 15. OTHER POWERS AND DUTIES. Subject to these By-laws and to such limitations as the Board of Directors may from time to time prescribe, the officers of the Corporation shall each have such powers and duties as generally pertain to their respective offices, as well as such powers and duties as from time to time may be conferred by the Board of Directors or the Chief Executive Officer. ARTICLE IV CAPITAL STOCK SECTION 1. CERTIFICATES OF STOCK. Each stockholder shall be entitled to a certificate of the capital stock of the Corporation in such form as may from time to time be prescribed by the Board of Directors. Such certificate shall be signed by the Chairman of the Board of Directors, the President or a Vice President and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary. The Corporation seal and the signatures by the Corporation's officers, the transfer agent or the registrar may be facsimiles. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed on such certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he or she were such officer, transfer agent or registrar at the time of its issue. Every certificate for shares of stock which are subject to any restriction on transfer and every certificate issued when the Corporation is authorized to issue more than one class or series of stock shall contain such legend with respect thereto as is required by law. SECTION 2. TRANSFERS. Subject to any restrictions on transfer and unless otherwise provided by the Board of Directors, shares of stock may be transferred only on the books of 11

SECTION 3. RECORD HOLDERS. Except as may otherwise be required by law, by the Certificate or by these By-laws, the Corporation shall be entitled to treat the record holder of stock as shown on its books as the owner of such stock for all purposes, including the payment of dividends and the right to vote with respect thereto, regardless of any transfer, pledge or other disposition of such stock, until the shares have been transferred on the books of the Corporation in accordance with the requirements of these By-laws. SECTION 4. RECORD DATE. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date: (a) in the case of determination of stockholders entitled to vote at any meeting of stockholders, shall, unless otherwise required by law, not be more than sixty nor less than ten days before the date of such meeting and (b) in the case of any other action, shall not be more than sixty days prior to such other action. If no record date is fixed: (i) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held and (ii) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

SECTION 2. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Subject to the operation of Section 4 of this Article V of these By-laws, each Director and Officer shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment) against any and all Expenses, judgments, penalties, fines and amounts reasonably paid in settlement that are incurred by such Director or Officer or on such Director's or Officer's behalf in connection with any threatened, pending or completed Proceeding or any claim, issue or matter therein, which such Director or Officer is, or is threatened to be made, a party to or participant in by reason of such Director's or Officer's Corporate Status, if such Director or Officer acted in good faith and in a manner such Director or Officer reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 2 shall continue as to a Director or Officer after he or she has ceased to be a Director or Officer and shall inure to the benefit of his or her heirs, executors, administrators and personal representatives. Notwithstanding the foregoing, the Corporation shall indemnify any Director or Officer seeking indemnification in connection with a Proceeding initiated by such Director or Officer only if such Proceeding was authorized by the Board of Directors of the Corporation, unless such Proceeding was brought to enforce an Officer or Director's rights to Indemnification or, in the case of Directors, advancement of Expenses under these By-laws in accordance with the provisions set forth herein. SECTION 3. INDEMNIFICATION OF NON-OFFICER EMPLOYEES. Subject to the operation of Section 4 of this Article V of these By-laws, each Non-Officer Employee may, in the discretion of the Board of Directors of the Corporation, be indemnified by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against any or all Expenses, judgments, penalties, fines and amounts reasonably paid in settlement that are incurred by such Non-Officer Employee or on such Non-Officer Employee's behalf in connection with any threatened, pending or completed Proceeding, or any claim, issue or matter therein, which such Non-Officer Employee is, or is threatened to be made, a party to or participant in by reason of such Non-Officer Employee's Corporate Status, if such Non-Officer Employee acted in good faith and in a manner such Non-Officer Employee reasonably believed to be in or not opposed to the best interests of the Corporation and, with 14

respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 3 shall exist as to a Non-Officer Employee after he or she has ceased to be a Non-Officer Employee and shall inure to the benefit of his or her heirs, personal representatives, executors and administrators. Notwithstanding the foregoing, the Corporation may indemnify any Non-Officer Employee seeking indemnification in connection with a Proceeding initiated by such Non-Officer Employee only if such Proceeding was authorized by the Board of Directors of the Corporation. SECTION 4. GOOD FAITH. Unless ordered by a court, no indemnification shall be provided pursuant to this Article V to a Director, to an Officer or to a Non-Officer Employee unless a determination shall have been made that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal Proceeding, such person had no reasonable cause to believe his or her conduct was unlawful. Such determination shall be made by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board of Directors, (b) a committee comprised of Disinterested Directors, such committee having been designated by a majority vote of the Disinterested Directors (even though less than a quorum), (c) if there are no such Disinterested Directors, or if a majority of Disinterested Directors so directs, by independent legal counsel in a written opinion, or (d) by the stockholders of the Corporation. SECTION 5. ADVANCEMENT OF EXPENSES TO DIRECTORS PRIOR TO FINAL DISPOSITION. (a) The Corporation shall advance all Expenses incurred by or on behalf of any Director in connection with any Proceeding in which such Director is involved by reason of such Director's Corporate Status within ten (10) days after the receipt by the Corporation of a written statement from such Director requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Director and shall be preceded or accompanied by an undertaking by or on behalf of such Director to repay any Expenses so advanced if it shall ultimately be determined that such Director is not entitled to be indemnified against such Expenses. (b) If a claim for advancement of Expenses hereunder by a Director is not paid in full by the Corporation within 10 days after receipt by the Corporation of documentation of Expenses and the required undertaking, such Director may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and if successful in whole or in part, such Director shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such advancement of Expenses under this Article V shall not be a defense to the action and shall not create a presumption that such advancement is not permissible. The 15

burden of proving that a Director is not entitled to an advancement of expenses shall be on the Corporation. (c) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Director has not met any applicable standard for indemnification set forth in the DGCL. SECTION 6. ADVANCEMENT OF EXPENSES TO OFFICERS AND NON-OFFICER EMPLOYEES PRIOR TO FINAL DISPOSITION. (a) The Corporation may, at the discretion of the Board of Directors of the Corporation, advance any or all Expenses incurred by or on behalf of any Officer and Non-Officer Employee in connection with any Proceeding in which such is involved by reason of the Corporate Status of such Officer or Non-Officer Employee upon the receipt by the Corporation of a statement or statements from such Officer or Non-Officer Employee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer and Non-Officer Employee and shall be preceded or accompanied by an undertaking by or on behalf of such to repay any Expenses so advanced if it shall ultimately be determined that such Officer or Non-Officer Employee is not entitled to be indemnified against such Expenses. (b) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Officer or Non-Officer Employee has not met any applicable standard for indemnification set forth in the DGCL. SECTION 7. CONTRACTUAL NATURE OF RIGHTS. (a) The foregoing provisions of this Article V shall be deemed to be a contract between the Corporation and each Director and Officer entitled to the benefits hereof at any time while this Article V is in effect, and any repeal or modification thereof shall not affect any rights or obligations then existing with respect to any state of facts then or theretofore existing or any Proceeding theretofore or thereafter brought based in whole or in part upon any such state of facts. (b) If a claim for indemnification of Expenses hereunder by a Director or Officer is not paid in full by the Corporation within 60 days after receipt by the Corporation of a written claim for indemnification, such Director or Officer may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, such Director or Officer shall also be entitled to be paid the expenses of prosecuting 16

such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel, or stockholders) to make a determination concerning the permissibility of such indemnification under this Article V shall not be a defense to the action and shall not create a presumption that such indemnification is not permissible. The burden of proving that a Director or Officer is not entitled to indemnification shall be on the Corporation. (c) In any suit brought by a Director or Officer to enforce a right to indemnification hereunder, it shall be a defense that such Director or Officer has not met any applicable standard for indemnification set forth in the DGCL. SECTION 8. NON-EXCLUSIVITY OF RIGHTS. The rights to indemnification and advancement of Expenses set forth in this Article V shall not be exclusive of any other right which any Director, Officer, or Non-Officer Employee may have or hereafter acquire under any statute, provision of the Certificate or these By-laws, agreement, vote of stockholders or Disinterested Directors or otherwise. SECTION 9. INSURANCE. The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer or Non-Officer Employee against any liability of any character asserted against or incurred by the Corporation or any such Director, Officer or Non-Officer Employee, or arising out of any such person's Corporate Status, whether or not the Corporation would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article V. ARTICLE VI MISCELLANEOUS PROVISIONS SECTION 1. FISCAL YEAR. The fiscal year of the Corporation shall be determined by the Board of Directors. SECTION 2. SEAL. The Board of Directors shall have power to adopt and alter the seal of the Corporation. SECTION 3. EXECUTION OF INSTRUMENTS. All deeds, leases, transfers, contracts, bonds, notes and other obligations to be entered into by the Corporation in the ordinary course of its business without director action may be executed on behalf of the Corporation by the Chairman of the Board, if one is elected, the President or the Treasurer or any other officer, employee or agent of the Corporation as the Board of Directors or Executive Committee may authorize. SECTION 4. VOTING OF SECURITIES. Unless the Board of Directors otherwise provides, the Chairman of the Board, if one is elected, the President or the Treasurer may waive notice of and act on behalf of this Corporation, or appoint another person or persons to act as proxy 17

or attorney in fact for this Corporation with or without discretionary power and/or power of substitution, at any meeting of stockholders or shareholders of any other corporation or organization, any of whose securities are held by this Corporation.

SECTION 8. AMENDMENT OF BY-LAWS. (a) AMENDMENT BY DIRECTORS. Except as provided otherwise by law, these By-laws may be amended or repealed by the Board of Directors by the affirmative vote of a majority of the directors then in office. (b) AMENDMENT BY STOCKHOLDERS. These By-laws may be amended or repealed at any Annual Meeting, or special meeting of stockholders called for such purpose, by the affirmative vote of at least 75% of the shares present in person or represented by proxy at such meeting and entitled to vote on such amendment or repeal, voting together as a single class; provided, however, that if the Board of Directors recommends that stockholders approve such amendment or repeal at such meeting of stockholders, such amendment or repeal shall only require the affirmative vote of the majority of the shares present in person or represented by proxy at such meeting and entitled to vote on such amendment or repeal, voting together as a single class. Notwithstanding the foregoing, stockholder approval shall not be required unless mandated by the Certificate, these By-laws, or other applicable law.

(the "Company") in connection with the preparation and filing with the Securities and Exchange Commission under the Securities Act of 1933 of a Registration Statement on Form S-1 (the "Registration Statement") relating to 7,359,950 shares of Common Stock, par value $.01 per share (the "Registered Shares"), including 6,250,000 primary shares to be sold by the Company (the "Primary Shares"), and 937,500 shares to be sold by the Company which the underwriters have an option to purchase solely for the purpose of covering over-allotments (the "Company Option Shares" and, together with the Primary Shares, the "Company Shares") and 172,450 shares to be sold by a stockholder of the Company named in the Registration Statement (the "Stockholder Shares"). The Registered Shares are to be sold to the several underwriters (the "Underwriters") of which Thomas Weisel Partners LLC, Dain Rauscher Incorporated and ING Barings LLC are the representatives (the "Representatives") pursuant to an Underwriting Agreement (the "Underwriting Agreement") to be entered into between the Company and the Representatives of the Underwriters. As counsel for the Company, we have examined the form of the proposed Underwriting Agreement being filed as an exhibit to the Registration Statement, the Company's Amended and Restated Certificate of Incorporation and the Company's Amended and Restated By-laws, each as will be in effect at the time of the issuance of the Registered Shares, and the Company's Certificate of Ownership and Merger as will be filed prior to the issuance of the Registered Shares and such records, certificates and other documents of the Company as we have deemed necessary or appropriate for the purposes of this opinion.

Based on the foregoing, we are of the opinion that (i) when the Company's Amended and Restated Certificate of Incorporation and the Certificate of Ownership and Merger are filed the Stockholder Shares will be duly authorized, legally issued, fully paid and non-assessable by the Company under the Delaware General Corporation Law (the "DGCL") and (ii) when the Underwriting Agreement is completed (including the insertion therein of pricing terms) and executed by the Company and on behalf of the Underwriters, and the Company Shares are sold to the Underwriters and paid for pursuant to the terms of the Underwriting Agreement, the Company Shares will be duly authorized, legally issued, fully paid and non-assessable by the Company under the DGCL. We hereby consent to being named as counsel to the Company in the Registration Statement, to the references therein to our firm under the caption "Legal Matters," and to the inclusion of this opinion as an exhibit to the Registration Statement. Very truly yours, /s/ GOODWIN, PROCTER & HOAR LLP GOODWIN, PROCTER & HOAR LLP

(vi) subject to the provisions of Section 5(a)(ii), to extend at any time the period in which Stock Options may be exercised; (vii) to determine at any time whether, to what extent, and under what circumstances distribution or the receipt of Stock and other amounts payable with respect to an Award shall be deferred either automatically or at the election of the grantee and whether and to what extent the Company shall pay or credit amounts constituting interest (at rates determined by the Administrator) or dividends or deemed dividends on such deferrals; and (viii) at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems advisable for the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan.

Any such delegation by the Administrator shall include a limitation as to the amount of Awards that may be granted during the period of the delegation and shall contain guidelines as to the determination of the exercise price of any Stock Option or Stock Appreciation Right, the conversion ratio or price of other Awards and the vesting criteria. The Administrator may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator's delegate or delegates that were consistent with the terms of the Plan. (d) INDEMNIFICATION. Neither the Board nor the Committee, nor any member of either or any delegatee thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Committee (and any delegatee thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, reasonable attorneys' fees) arising or resulting therefrom to the fullest extent permitted by law and/or under any directors' and officers' liability insurance coverage which may be in effect from time to time. 4

SECTION 3. STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION (a) STOCK ISSUABLE. Subject to adjustment as provided in Section 3(b), the maximum number of shares of Stock reserved and available for issuance under the Plan shall be such aggregate number of shares of Stock as does not exceed the sum of (i) three million seven hundred fifty thousand (3,750,000) shares; plus (ii) as of each June 30 and December 31 following the closing of the Company's initial public offering, an additional positive number equal to fifteen percent (15%) of the shares of Stock issued by the Company during the six-month period then ended (excluding shares issued in the Company's initial public offering); provided that not more than three million seven hundred fifty thousand (3,750,000) shares shall be issued in the form of Unrestricted Stock Awards, Restricted Stock Awards, or Performance Share Awards except to the extent such Awards are granted in lieu of cash compensation or fees. For purposes of this limitation, the shares of Stock underlying any Awards which are forfeited, canceled, reacquired by the Company, satisfied without the issuance of Stock or otherwise terminated (other than by exercise) shall be added back to the shares of Stock available for issuance under the Plan. Subject to such overall limitation, shares of Stock may be issued up to such maximum number pursuant to any type or types of Award; provided, however, that Stock Options or Stock Appreciation Rights with respect to no more than 1,000,000 shares of Stock may be granted to any one individual grantee during any one calendar year period. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the Company and held in its treasury. (b) CHANGES IN STOCK. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company's capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for a different number or kind of securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, including the maximum number of shares that may be issued in the form of Unrestricted Stock Awards, Restricted Stock Awards or Performance Share Awards, (ii) the number of Stock Options or Stock Appreciation Rights that can be granted to any one individual grantee and the maximum number of shares that may be granted under a Performance-based Award, (iii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iv) the repurchase price per share subject to each outstanding Restricted Stock Award, and (v) the price for each share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The adjustment by the 5

Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares. The Administrator may also adjust the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration material changes in accounting practices or principles, extraordinary dividends, acquisitions or dispositions of stock or property or any other event if it is determined by the Administrator that such adjustment is appropriate to avoid distortion in the operation of the Plan, provided that no such adjustment shall be made in the case of an Incentive Stock Option, without the consent of the grantee, if it would constitute a modification, extension or renewal of the Option within the meaning of Section 424(h) of the Code. (c) MERGERS AND OTHER TRANSACTIONS. In the case of and subject to the consummation of (i) the dissolution or liquidation of the Company, (ii) the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated person or entity, (iii) a merger, reorganization or consolidation in which the outstanding shares of Stock are converted into or exchanged for a different kind of securities of the successor entity and the holders of the Company's outstanding voting power immediately prior to such transaction do not own a majority of the outstanding voting power of the successor entity immediately upon completion of such transaction, or (iv) the sale of all of the Stock of the Company to an unrelated person or entity (in each case, a "Sale Event"), all Options and Stock Appreciation Rights that are not exercisable immediately prior to the effective time of the Sale Event shall become fully exercisable as of the effective time of the Sale Event and all other Awards with conditions and restrictions relating solely to the passage of time and continued employment shall become fully vested and nonforfeitable as of the effective time of the Sale Event, except as the Administrator may otherwise specify with respect to particular Awards. Upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder shall terminate, unless provision is made in connection with the Sale Event in the sole discretion of the parties thereto for the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree (after taking into account any acceleration hereunder). In the event of such termination, each grantee shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to exercise all outstanding Options and Stock Appreciation Rights held by such grantee, including those that will become exercisable upon the consummation of the Sale Event; provided, however, that the exercise of Options and Stock Appreciation Rights not exercisable prior to the Sale Event shall be subject to the consummation of the Sale Event. Notwithstanding anything to the contrary in this Section 3.2(c), in the event of a Sale Event pursuant to which holders of the Stock of the Company will receive upon consummation thereof a cash payment for each share surrendered in the Sale Event, the Company shall have the right, but not the obligation, to make or provide for a cash payment to the grantees holding 6

Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the value as determined by the Administrator of the consideration payable per share of Stock pursuant to the Sale Event (the "Sale Price") times the number of shares of Stock subject to outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options and Stock Appreciation Rights. (d) SUBSTITUTE AWARDS. The Administrator may grant Awards under the Plan in substitution for stock and stock based awards held by employees, directors or other key persons of another corporation in connection with the merger or consolidation of the employing corporation with the Company or a Subsidiary or the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The Administrator may direct that the substitute awards be granted on such terms and conditions as the Administrator considers appropriate in the circumstances. Any substitute Awards granted under the Plan shall not count against the share limitation set forth in Section 3(a). SECTION 4. ELIGIBILITY Grantees under the Plan will be such full or part-time officers and other employees, Independent Directors and key persons (including consultants and prospective employees) of the Company and its Subsidiaries as are selected from time to time by the Administrator in its sole discretion. SECTION 5. STOCK OPTIONS Any Stock Option granted under the Plan shall be in such form as the Administrator may from time to time approve. Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a "subsidiary corporation" within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option. No Incentive Stock Option shall be granted under the Plan after October 26, 2010. (a) STOCK OPTIONS GRANTED TO EMPLOYEES AND KEY PERSONS. The Administrator in its discretion may grant Stock Options to eligible employees and key persons of the Company or any Subsidiary. Stock Options granted pursuant to this Section 5(a) shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines, Stock Options may be granted in lieu of cash compensation at the optionee's election, subject to such terms and conditions as the Administrator may establish. 7

(i) EXERCISE PRICE. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5(a) shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant in the case of Incentive Stock Options, or 85 percent of the Fair Market Value on the date of grant, in the case of Non-Qualified Stock Options (other than options granted in lieu of cash compensation). If an employee owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the option price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date. (ii) OPTION TERM. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than 10 years after the date the Stock Option is granted. If an employee owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the term of such Stock Option shall be no more than five years from the date of grant. (iii) EXERCISABILITY; RIGHTS OF A STOCKHOLDER. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. (iv) METHOD OF EXERCISE. Stock Options may be exercised in whole or in part, by giving written notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods to the extent provided in the Option Award agreement: (A) In cash, by certified or bank check or other instrument acceptable to the Administrator; (B) Through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the optionee on the open market or that have been beneficially owned by the optionee for at least six months and are not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date; (C) By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company 8

for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure; or (D) By the optionee delivering to the Company a promissory note if the Board has expressly authorized the loan of funds to the optionee for the purpose of enabling or assisting the optionee to effect the exercise of his Stock Option; provided that at least so much of the exercise price as represents the par value of the Stock shall be paid other than with a promissory note if otherwise required by state law. Payment instruments will be received subject to collection. The delivery of certificates representing the shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Option Award agreement or applicable provisions of laws. In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of shares attested to. (v) ANNUAL LIMIT ON INCENTIVE STOCK OPTIONS. To the extent required for "incentive stock option" treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option. (b) RELOAD OPTIONS. At the discretion of the Administrator, Options granted under the Plan may include a "reload" feature pursuant to which an optionee exercising an option by the delivery of a number of shares of Stock in accordance with Section 5(a)(iv)(B) hereof would automatically be granted an additional Option (with an exercise price equal to the Fair Market Value of the Stock on the date the additional Option is granted and with such other terms as the Administrator may provide) to purchase that number of shares of Stock equal to the sum of (i) the number delivered to exercise the original Option and (ii) the number withheld to satisfy tax liabilities, with an Option term equal to the remainder of the original Option term unless the Administrator otherwise determines in the Award agreement for the original Option grant. 9

(c) STOCK OPTIONS GRANTED TO INDEPENDENT DIRECTORS. (i) AUTOMATIC GRANT OF OPTIONS. (A) Each person who is an Independent Director on the effective date of the Initial Public Offering, other than Christopher W. Dick and Richard C. Klaffky, Jr., shall be granted a Non-Qualified Stock Option to acquire 10,000 shares of Stock. (B) Each Independent Director who is first elected to serve as a Director after the Initial Public Offering shall be granted, on the fifth business day after his election, a Non-Qualified Stock Option to acquire 10,000 shares of Stock. (C) Each Independent Director, other than Christopher W. Dick and Richard C. Klaffky, Jr., who is serving as Director of the Company on the fifth business day after each annual meeting of shareholders, beginning with the 2001 annual meeting, shall automatically be granted on such day a Non-Qualified Stock Option to acquire 2,500 shares of Stock. (D) The exercise price per share for the Stock covered by a Stock Option granted under this Section 5(c) shall be equal to the Fair Market Value of the Stock on the date the Stock Option is granted. (E) The Administrator, in its discretion, may grant additional Non-Qualified Stock Options to Independent Directors. Any such grant may vary among individual Independent Directors. (ii) EXERCISE; TERMINATION. (A) Unless otherwise determined by the Administrator, an Option granted under Section 5(c) shall be exercisable as to one-third of the shares of Stock covered thereby as of the first anniversary of the grant date, as to a second one-third of the shares of Stock covered thereby as of the second anniversary of the grant date, and as to the remaining one-third of the shares of Stock covered thereby as of the third anniversary of the grant date. An Option issued under this Section 5(c) shall not be exercisable after the expiration of ten years from the date of grant. (B) Options granted under this Section 5(c) may be exercised only by written notice to the Company specifying the number of shares to be purchased. Payment of the full purchase price of the shares to be purchased may be made by one or more of the methods specified in Section 5(a)(iv). An optionee shall 10

have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. (d) NON-TRANSFERABILITY OF OPTIONS. No Stock Option shall be transferable by the optionee otherwise than by will or by the laws of descent and distribution and all Stock Options shall be exercisable, during the optionee's lifetime, only by the optionee, or by the optionee's legal representative or guardian in the event of the optionee's incapacity. Notwithstanding the foregoing, the Administrator, in its sole discretion, may provide in the Award agreement regarding a given Option that the optionee may transfer his Non-Qualified Stock Options to members of his immediate family, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Option. SECTION 6. STOCK APPRECIATION RIGHTS. (a) NATURE OF STOCK APPRECIATION RIGHTS. A Stock Appreciation Right is an Award entitling the recipient to receive an amount in cash or shares of Stock or a combination thereof having a value equal to the excess of the Fair Market Value of the Stock on the date of exercise over the exercise price Stock Appreciation Right, which price shall not be less than 85 percent of the Fair Market Value of the Stock on the date of grant (or more than the option exercise price per share, if the Stock Appreciation Right was granted in tandem with a Stock Option) multiplied by the number of shares of Stock with respect to which the Stock Appreciation Right shall have been exercised, with the Administrator having the right to determine the form of payment. (b) GRANT AND EXERCISE OF STOCK APPRECIATION RIGHTS. Stock Appreciation Rights may be granted by the Administrator in tandem with, or independently of, any Stock Option granted pursuant to Section 5 of the Plan. In the case of a Stock Appreciation Right granted in tandem with a Non-Qualified Stock Option, such Stock Appreciation Right may be granted either at or after the time of the grant of such Option. In the case of a Stock Appreciation Right granted in tandem with an Incentive Stock Option, such Stock Appreciation Right may be granted only at the time of the grant of the Option. A Stock Appreciation Right or applicable portion thereof granted in tandem with a Stock Option shall terminate and no longer be exercisable upon the termination or exercise of the related Option. (c) TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS. Stock Appreciation Rights shall be subject to such terms and conditions as shall be determined from time to time by the Administrator, subject to the following: 11

(i) Stock Appreciation Rights granted in tandem with Options shall be exercisable at such time or times and to the extent that the related Stock Options shall be exercisable. (ii) Upon exercise of a Stock Appreciation Right, the applicable portion of any related Option shall be surrendered. (iii) All Stock Appreciation Rights shall be exercisable during the grantee's lifetime only by the grantee or the grantee's legal representative. SECTION 7. RESTRICTED STOCK AWARDS (a) NATURE OF RESTRICTED STOCK AWARDS. A Restricted Stock Award is an Award entitling the recipient to acquire, at such purchase price as determined by the Administrator, shares of Stock subject to such restrictions and conditions as the Administrator may determine at the time of grant ("Restricted Stock"). Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The grant of a Restricted Stock Award is contingent on the grantee executing the Restricted Stock Award agreement. The terms and conditions of each such agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. (b) RIGHTS AS A STOCKHOLDER. Upon execution of a written instrument setting forth the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the Restricted Stock, subject to such conditions contained in the written instrument evidencing the Restricted Stock Award. Unless the Administrator shall otherwise determine, certificates evidencing the Restricted Stock shall remain in the possession of the Company until such Restricted Stock is vested as provided in Section 7(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank. (c) RESTRICTIONS. Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Restricted Stock Award agreement. If a grantee's employment (or other service relationship) with the Company and its Subsidiaries terminates for any reason, the Company shall have the right to repurchase Restricted Stock that has not vested at the time of termination at its original purchase price, from the grantee or the grantee's legal representative. (d) VESTING OF RESTRICTED STOCK. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Stock and the Company's right of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Stock 12

and shall be deemed "vested." Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, a grantee's rights in any shares of Restricted Stock that have not vested shall automatically terminate upon the grantee's termination of employment (or other service relationship) with the Company and its Subsidiaries and such shares shall be subject to the Company's right of repurchase as provided in Section 7(c) above. (e) WAIVER, DEFERRAL AND REINVESTMENT OF DIVIDENDS. The Restricted Stock Award agreement may require or permit the immediate payment, waiver, deferral or investment of dividends paid on the Restricted Stock. SECTION 8. DEFERRED STOCK AWARDS (a) NATURE OF DEFERRED STOCK AWARDS. A Deferred Stock Award is an Award of phantom stock units to a grantee, subject to restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The grant of a Deferred Stock Award is contingent on the grantee executing the Deferred Stock Award agreement. The terms and conditions of each such agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. At the end of the deferral period, the Deferred Stock Award, to the extent vested, shall be paid to the grantee in the form of shares of Stock. (b) ELECTION TO RECEIVE DEFERRED STOCK AWARDS IN LIEU OF COMPENSATION. The Administrator may, in its sole discretion, permit a grantee to elect to receive a portion of the cash compensation or Restricted Stock Award otherwise due to such grantee in the form of a Deferred Stock Award. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with rules and procedures established by the Administrator. The Administrator shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate. (c) RIGHTS AS A STOCKHOLDER. During the deferral period, a grantee shall have no rights as a stockholder; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the phantom stock units underlying his Deferred Stock Award, subject to such terms and conditions as the Administrator may determine. (d) RESTRICTIONS. A Deferred Stock Award may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of during the deferral period. (e) TERMINATION. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, a grantee's right in all Deferred Stock Awards that have not vested shall 13

automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason. SECTION 9. UNRESTRICTED STOCK AWARDS GRANT OR SALE OF UNRESTRICTED STOCK. The Administrator may, in its sole discretion, grant (or sell at par value or such higher purchase price determined by the Administrator) an Unrestricted Stock Award to any grantee pursuant to which such grantee may receive shares of Stock free of any restrictions ("Unrestricted Stock") under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to such grantee. SECTION 10. PERFORMANCE SHARE AWARDS (a) NATURE OF PERFORMANCE SHARE AWARDS. A Performance Share Award is an Award entitling the recipient to acquire shares of Stock upon the attainment of specified performance goals. The Administrator may make Performance Share Awards independent of or in connection with the granting of any other Award under the Plan. The Administrator in its sole discretion shall determine whether and to whom Performance Share Awards shall be made, the performance goals, the periods during which performance is to be measured, and all other limitations and conditions. (b) RIGHTS AS A STOCKHOLDER. A grantee receiving a Performance Share Award shall have the rights of a stockholder only as to shares actually received by the grantee under the Plan and not with respect to shares subject to the Award but not actually received by the grantee. A grantee shall be entitled to receive a stock certificate evidencing the acquisition of shares of Stock under a Performance Share Award only upon satisfaction of all conditions specified in the Performance Share Award agreement (or in a performance plan adopted by the Administrator). (c) TERMINATION. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, a grantee's rights in all Performance Share Awards shall automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason. (d) ACCELERATION, WAIVER, ETC. At any time prior to the grantee's termination of employment (or other service relationship) by the Company and its Subsidiaries, the Administrator may in its sole discretion accelerate, waive or, subject to Section 15, amend any or all of the goals, restrictions or conditions applicable to a Performance Share Award. 14

SECTION 11. PERFORMANCE-BASED AWARDS TO COVERED EMPLOYEES Notwithstanding anything to the contrary contained herein, if any Restricted Stock Award, Deferred Stock Award or Performance Share Award granted to a Covered Employee is intended to qualify as "Performance-based Compensation" under Section 162(m) of the Code and the regulations promulgated thereunder (a "Performance-based Award"), such Award shall comply with the provisions set forth below: (a) PERFORMANCE CRITERIA. The performance criteria used in performance goals governing Performance-based Awards granted to Covered Employees may include any or all of the following: (i) the Company's return on equity, assets, capital or investment, (ii) pre-tax or after-tax profit levels of the Company or any Subsidiary, a division, an operating unit or a business segment of the Company, or any combination of the foregoing; (iii) cash flow, funds from operations or similar measure; (iv) total shareholder return; (v) changes in the market price of the Stock; (vi) sales or market share; or (vii) earnings per share. (b) GRANT OF PERFORMANCE-BASED AWARDS. With respect to each Performance-based Award granted to a Covered Employee, the Committee shall select, within the first 90 days of a Performance Cycle (or, if shorter, within the maximum period allowed under Section 162(m) of the Code) the performance criteria for such grant, and the achievement targets with respect to each performance criterion (including a threshold level of performance below which no amount will become payable with respect to such Award). Each Performance-based Award will specify the amount payable, or the formula for determining the amount payable, upon achievement of the various applicable performance targets. The performance criteria established by the Committee may be (but need not be) different for each Performance Cycle and different goals may be applicable to Performance-based Awards to different Covered Employees. (c) PAYMENT OF PERFORMANCE-BASED AWARDS. Following the completion of a Performance Cycle, the Committee shall meet to review and certify in writing whether, and to what extent, the performance criteria for the Performance Cycle have been achieved and, if so, to also calculate and certify in writing the amount of the Performance-based Awards earned for the Performance Cycle. The Committee shall then determine the actual size of each Covered Employee's Performance-based Award, and, in doing so, may reduce or eliminate the amount of the Performance-based Award for a Covered Employee if, in its sole judgment, such reduction or elimination is appropriate. (d) MAXIMUM AWARD PAYABLE. The maximum Performance-based Award payable to any one Covered Employee under the Plan for a Performance Cycle is 500,000 Shares (subject to adjustment as provided in Section 3(b) hereof). 15

SECTION 12. DIVIDEND EQUIVALENT RIGHTS (a) DIVIDEND EQUIVALENT RIGHTS. A Dividend Equivalent Right is an Award entitling the grantee to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend Equivalent Right (or other award to which it relates) if such shares had been issued to and held by the grantee. A Dividend Equivalent Right may be granted hereunder to any grantee as a component of another Award or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in the Award agreement. Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a component of another Award may provide that such Dividend Equivalent Right shall be settled upon exercise, settlement, or payment of, or lapse of restrictions on, such other award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under the same conditions as such other award. A Dividend Equivalent Right granted as a component of another Award may also contain terms and conditions different from such other award. (b) INTEREST EQUIVALENTS. Any Award under this Plan that is settled in whole or in part in cash on a deferred basis may provide in the grant for interest equivalents to be credited with respect to such cash payment. Interest equivalents may be compounded and shall be paid upon such terms and conditions as may be specified by the grant. (c) TERMINATION. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, a grantee's rights in all Dividend Equivalent Rights or interest equivalents shall automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason. SECTION 13. TAX WITHHOLDING (a) PAYMENT BY GRANTEE. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the grantee for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company's obligation to deliver stock certificates to any grantee is subject to and conditioned on tax obligations being satisfied by the grantee. 16

(b) PAYMENT IN STOCK. Subject to approval by the Administrator, a grantee may elect to have the minimum required tax withholding obligation satisfied, in whole or in part, by (i) authorizing the Company to withhold from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due, or (ii) transferring to the Company shares of Stock owned by the grantee with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due. SECTION 14. TRANSFER, LEAVE OF ABSENCE, ETC. For purposes of the Plan, the following events shall not be deemed a termination of employment: (a) a transfer to the employment of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another; or (b) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee's right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing. SECTION 15. AMENDMENTS AND TERMINATION The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder's consent. If and to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code or to ensure that compensation earned under Awards qualifies as performance-based compensation under Section 162(m) of the Code, if and to the extent intended to so qualify, Plan amendments shall be subject to approval by the Company stockholders entitled to vote at a meeting of stockholders. Nothing in this Section 15 shall limit the Administrator's authority to take any action permitted pursuant to Section 3(c). SECTION 16. STATUS OF PLAN With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company's obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence. 17

SECTION 17. CHANGE OF CONTROL PROVISIONS Upon the occurrence of a Change of Control as defined in this Section 17: (a) Except as otherwise provided in the applicable Award agreement, each outstanding Stock Option and Stock Appreciation Right shall automatically become fully exercisable. (b) Except as otherwise provided in the applicable Award Agreement, conditions and restrictions on each outstanding Restricted Stock Award, Deferred Stock Award and Performance Share Award which relate solely to the passage of time and continued employment will be removed. Performance or other conditions (other than conditions and restrictions relating solely to the passage of time and continued employment) will continue to apply unless otherwise provided in the applicable Award agreement. (c) "Change of Control" shall mean the occurrence of any one of the following events: (i) any "Person," as such term is used in Sections 13(d) and 14(d) of the Act (other than the Company, any of its Subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its Subsidiaries), together with all "affiliates" and "associates" (as such terms are defined in Rule 12b-2 under the Exchange Act) of such person, shall become the "beneficial owner" (as such term is defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 25 percent or more of the combined voting power of the Company's then outstanding securities having the right to vote in an election of the Company's Board of Directors ("Voting Securities") (in such case other than as a result of an acquisition of securities directly from the Company); or (ii) persons who, as of the Effective Date, constitute the Company's Board of Directors (the "Incumbent Directors") cease for any reason, including, without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of the Board, provided that any person becoming a director of the Company subsequent to the Effective Date shall be considered an Incumbent Director if such person's election was approved by or such person was nominated for election by either (A) a vote of at least a majority of the Incumbent Directors or (B) a vote of at least a majority of the Incumbent Directors who are members of a nominating committee comprised, in the majority, of Incumbent Directors; but provided further, that any such person whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of members of the Board of Directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board, including by reason of agreement intended to 18

avoid or settle any such actual or threatened contest or solicitation, shall not be considered an Incumbent Director; or (iii) the consummation of a consolidation, merger or consolidation or sale or other disposition of all or substantially all of the assets of the Company (a "Corporate Transaction"); excluding, however, a Corporate Transaction in which the stockholders of the Company immediately prior to the Corporate Transaction, would, immediately after the Corporate Transaction, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than 50 percent of the voting shares of the corporation issuing cash or securities in the Corporate Transaction (or of its ultimate parent corporation, if any); or (iv) the approval by the stockholders of any plan or proposal for the liquidation or dissolution of the Company. Notwithstanding the foregoing, a "Change of Control" shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as the result of an acquisition of securities by the Company which, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of shares of Voting Securities beneficially owned by any person to 25 percent or more of the combined voting power of all then outstanding Voting Securities; PROVIDED, HOWEVER, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns 25 percent or more of the combined voting power of all then outstanding Voting Securities, then a "Change of Control" shall be deemed to have occurred for purposes of the foregoing clause (i). SECTION 18. GENERAL PROVISIONS (a) NO DISTRIBUTION; COMPLIANCE WITH LEGAL REQUIREMENTS. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof. No shares of Stock shall be issued pursuant to an Award until all applicable securities law and other legal and stock exchange or similar requirements have been satisfied. The Administrator may require the placing of such stop-orders and restrictive legends on certificates for Stock and Awards as it deems appropriate. (b) DELIVERY OF STOCK CERTIFICATES. Stock certificates to grantees under this Plan shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee's last known address on file with the Company. 19

(c) OTHER COMPENSATION ARRANGEMENTS; NO EMPLOYMENT RIGHTS. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary. (d) TRADING POLICY RESTRICTIONS. Option exercises and other Awards under the Plan shall be subject to such Company's insider trading policy, as in effect from time to time. (e) LOANS TO GRANTEES. The Company shall have the authority to make loans to grantees of Awards hereunder (including to facilitate the purchase of shares) and shall further have the authority to issue shares for promissory notes hereunder. (f) DESIGNATION OF BENEFICIARY. Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee's death. Any such designation shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee's estate. SECTION 19. EFFECTIVE DATE OF PLAN This Plan shall become effective upon approval by the holders of a majority of the votes cast at a meeting of stockholders at which a quorum is present. Subject to such approval by the stockholders and to the requirement that no Stock may be issued hereunder prior to such approval, Stock Options and other Awards may be granted hereunder on and after adoption of this Plan by the Board. SECTION 20. GOVERNING LAW This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of Delaware, applied without regard to conflict of law principles.

Exhibit 10.3 HARVARD BIOSCIENCE, INC. EMPLOYEE STOCK PURCHASE PLAN The purpose of the Harvard Bioscience, Inc. Employee Stock Purchase Plan ("the Plan") is to provide eligible employees of Harvard Bioscience, Inc. (the "Company") and certain of its subsidiaries with opportunities to purchase shares of the Company's common stock, par value $.01 per share (the "Common Stock"). Five hundred thousand (500,000) shares of Common Stock in the aggregate have been approved and reserved for this purpose. The Plan is intended to constitute an "employee stock purchase plan" within the meaning of Section 423(b) of the Internal Revenue Code of 1986, as amended (the "Code"), and shall be interpreted in accordance with that intent. 1. ADMINISTRATION. The Plan will be administered by the person or persons (the "Administrator") appointed by the Company's Board of Directors (the "Board") for such purpose. The Administrator has authority to make rules and regulations for the administration of the Plan, and its interpretations and decisions with regard thereto shall be final and conclusive. No member of the Board or individual exercising administrative authority with respect to the Plan shall be liable for any action or determination made in good faith with respect to the Plan or any option granted hereunder. 2. OFFERINGS. The Company will make one or more offerings to eligible employees to purchase Common Stock under the Plan ("Offerings"). Unless otherwise determined by the Administrator, the initial Offering will begin on January 1, 2001 and will end on June 30, 2001 (the "Initial Offering"). Thereafter, unless otherwise determined by the Administrator, an Offering will begin on the first business day occurring on or after each January 1 and July 1

and will end on the last business day occurring on or before the following June 30 and December 31, respectively. The Administrator may, in its discretion, designate a different period for any Offering, provided that no Offering shall exceed six months in duration or overlap any other Offering. 3. ELIGIBILITY. All employees of the Company (including employees who are also directors of the Company) and all employees of each Designated Subsidiary (as defined in Section 11) are eligible to participate in any one or more of the Offerings under the Plan, provided that as of the first day of the applicable Offering (the "Offering Date") they are customarily employed by the Company or a Designated Subsidiary for more than 20 hours a week. 4. PARTICIPATION. An employee eligible on any Offering Date may participate in such Offering by submitting an enrollment form to his appropriate payroll location at least 15 business days before the Offering Date (or by such other deadline as shall be established for the Offering). The form will (a) state a whole percentage to be deducted from his Compensation (as defined in Section 11) per pay period, (b) authorize the purchase of Common Stock for him in each Offering in accordance with the terms of the Plan and (c) specify the exact name or names in which shares of Common Stock purchased for him are to be issued pursuant to Section 10. An employee who does not enroll in accordance with these procedures will be deemed to have waived his right to participate. Unless an employee files a new enrollment form or withdraws from the Plan, his deductions and purchases will continue at the same percentage of Compensation for future Offerings, provided he remains eligible. 2

Notwithstanding the foregoing, participation in the Plan will neither be permitted nor be denied contrary to the requirements of the Code. 5. EMPLOYEE CONTRIBUTIONS. Each eligible employee may authorize payroll deductions at a minimum of one percent (1%) up to a maximum of ten percent (10%) of his Compensation for each pay period. The Company will maintain book accounts showing the amount of payroll deductions made by each participating employee for each Offering. No interest will accrue or be paid on payroll deductions. 6. DEDUCTION CHANGES. Except as may be determined by the Administrator in advance of an Offering, an employee may not increase or decrease his payroll deduction during any Offering, but may increase or decrease his payroll deduction with respect to the next Offering (subject to the limitations of Section 5) by filing a new enrollment form at least 15 business days before the next Offering Date (or by such other deadline as shall be established for the Offering). The Administrator may, in advance of any Offering, establish rules permitting an employee to increase, decrease or terminate his payroll deduction during an Offering. 7. WITHDRAWAL. An employee may withdraw from participation in the Plan by delivering a written notice of withdrawal to his appropriate payroll location. The employee's withdrawal will be effective as of the next business day. Following an employee's withdrawal, the Company will promptly refund to him his entire account balance under the Plan (after payment for any Common Stock purchased before the effective date of withdrawal). Partial withdrawals are not permitted. The employee may not begin participation again during the 3

remainder of the Offering, but may enroll in a subsequent Offering in accordance with Section 4. 8. GRANT OF OPTIONS. On each Offering Date, the Company will grant to each eligible employee who is then a participant in the Plan an option ("Option") to purchase on the last day of such Offering (the "Exercise Date"), at the Option Price hereinafter provided for, (a) a number of shares of Common Stock, which number shall not exceed the number of whole shares which is less than or equal to $12,500 divided by the closing price per share of Common Stock on the Offering Date, or (b) such other lesser maximum number of shares as shall have been established by the Administrator in advance of the Offering. The purchase price for each share purchased under each Option (the "Option Price") will be 85% of the Fair Market Value of the Common Stock on the Offering Date or the Exercise Date, whichever is less. Notwithstanding the foregoing, no employee may be granted an option hereunder if such employee, immediately after the option was granted, would be treated as owning stock, possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or any Parent or Subsidiary (as defined in Section 11). For purposes of the preceding sentence, the attribution rules of Section 424(d) of the Code shall apply in determining the stock ownership of an employee, and all stock which the employee has a contractual right to purchase shall be treated as stock owned by the employee. In addition, no employee may be granted an Option which permits his rights to purchase stock under the Plan, and any other employee stock purchase plan of the Company and its Parents and Subsidiaries, to accrue at a rate which exceeds $25,000 of the fair market value of such stock (determined on 4

the option grant date or dates) for each calendar year in which the Option is outstanding at any time. The purpose of the limitation in the preceding sentence is to comply with Section 423(b)(8) of the Code. 9. EXERCISE OF OPTION AND PURCHASE OF SHARES. Each employee who continues to be a participant in the Plan on the Exercise Date shall be deemed to have exercised his Option on such date and shall acquire from the Company such number of whole shares of Common Stock reserved for the purpose of the Plan as his accumulated payroll deductions on such date will purchase at the Option Price, subject to any other limitations contained in the Plan. Any amount remaining in an employee's account at the end of an Offering solely by reason of the inability to purchase a fractional share will be carried forward to the next Offering; any other balance remaining in an employee's account at the end of an Offering will be refunded to the employee promptly. 10. ISSUANCE OF CERTIFICATES. Certificates representing shares of Common Stock purchased under the Plan may be issued only in the name of the employee, in the name of the employee and another person of legal age as joint tenants with rights of survivorship, or in the name of a broker authorized by the employee to be his, or their, nominee for such purpose. 11. DEFINITIONS. The term "Compensation" means the amount of base pay, prior to salary reduction pursuant to either Section 125 or 401(k) of the Code, but excluding overtime, commissions, incentive or bonus awards, allowances and reimbursements for expenses such as relocation allowances or travel expenses, income or gains on the exercise of Company stock options, and similar items. 5

The term "Designated Subsidiary" means any present or future Subsidiary (as defined below) that has been designated by the Board to participate in the Plan. The Board may so designate any Subsidiary, or revoke any such designation, at any time and from time to time, either before or after the Plan is approved by the stockholders. The term "Fair Market Value of the Common Stock" on any given date means the fair market value of the Common Stock determined in good faith by the Administrator; PROVIDED, HOWEVER, that if the Common Stock is admitted to quotation on the National Association of Securities Dealers Automated Quotation System ("Nasdaq"), Nasdaq National System or national securities exchange, the determination shall be made by reference to market quotations. If there are no market quotations for such date, the determination shall be made by reference to the last date preceding such date for which there are market quotations. The term "Initial Public Offering" means the consummation of the first fully underwritten, firm commitment public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended, other than on Forms S-4 or S-8 or their then equivalents, covering the offer and sale by the Company of its Common Stock. The term "Parent" means a "parent corporation" with respect to the Company, as defined in Section 424(e) of the Code. The term "Subsidiary" means a "subsidiary corporation" with respect to the Company, as defined in Section 424(f) of the Code. 12. RIGHTS ON TERMINATION OF EMPLOYMENT. If a participating employee's employment terminates for any reason before the Exercise Date for any Offering, no payroll deduction will be taken from any pay due and owing to the employee and the balance in his 6

account will be paid to him or, in the case of his death, to his designated beneficiary as if he had withdrawn from the Plan under Section 7. An employee will be deemed to have terminated employment, for this purpose, if the corporation that employs him, having been a Designated Subsidiary, ceases to be a Subsidiary, or if the employee is transferred to any corporation other than the Company or a Designated Subsidiary. 13. SPECIAL RULES. Notwithstanding anything herein to the contrary, the Administrator may adopt special rules applicable to the employees of a particular Designated Subsidiary, whenever the Administrator determines that such rules are necessary or appropriate for the implementation of the Plan in a jurisdiction where such Designated Subsidiary has employees; provided that such rules are consistent with the requirements of Section 423(b) of the Code. Such special rules may include (by way of example, but not by way of limitation) the establishment of a method for employees of a given Designated Subsidiary to fund the purchase of shares other than by payroll deduction, if the payroll deduction method is prohibited by local law or is otherwise impracticable. Any special rules established pursuant to this Section 13 shall, to the extent possible, result in the employees subject to such rules having substantially the same rights as other participants in the Plan. 14. OPTIONEES NOT STOCKHOLDERS. Neither the granting of an Option to an employee nor the deductions from his pay shall constitute such employee a holder of the shares of Common Stock covered by an Option under the Plan until such shares have been purchased by and issued to him. 7

15. RIGHTS NOT TRANSFERABLE. Rights under the Plan are not transferable by a participating employee other than by will or the laws of descent and distribution, and are exercisable during the employee's lifetime only by the employee. 16. APPLICATION OF FUNDS. All funds received or held by the Company under the Plan may be combined with other corporate funds and may be used for any corporate purpose. 17. ADJUSTMENT IN CASE OF CHANGES AFFECTING COMMON STOCK. In the event of a subdivision of outstanding shares of Common Stock, or the payment of a dividend in Common Stock, the number of shares approved for the Plan, and the share limitation set forth in Section 8, shall be increased proportionately, and such other adjustments shall be made as may be deemed equitable by the Administrator. In the event of any other change affecting the Common Stock, such adjustment shall be made as may be deemed equitable by the Administrator to give proper effect to such event. 18. AMENDMENT OF THE PLAN. The Board may at any time, and from time to time, amend the Plan in any respect, except that without the approval, within 12 months of such Board action, by the stockholders, no amendment shall be made increasing the number of shares approved for the Plan or making any other change that would require stockholder approval in order for the Plan, as amended, to qualify as an "employee stock purchase plan" under Section 423(b) of the Code. 19. INSUFFICIENT SHARES. If the total number of shares of Common Stock that would otherwise be purchased on any Exercise Date plus the number of shares purchased under previous Offerings under the Plan exceeds the maximum number of shares issuable under the Plan, the shares then available shall be apportioned among participants in proportion to the 8

amount of payroll deductions accumulated on behalf of each participant that would otherwise be used to purchase Common Stock on such Exercise Date. 20. TERMINATION OF THE PLAN. The Plan may be terminated at any time by the Board. Upon termination of the Plan, all amounts in the accounts of participating employees shall be promptly refunded. 21. GOVERNMENTAL REGULATIONS. The Company's obligation to sell and deliver Common Stock under the Plan is subject to obtaining all governmental approvals required in connection with the authorization, issuance, or sale of such stock. The Plan shall be governed by Delaware law except to the extent that such law is preempted by federal law. 22. ISSUANCE OF SHARES. Shares may be issued upon exercise of an Option from authorized by unissued Common Stock, from shares held in the treasury of the Company, or from any other proper source. 23. TAX WITHHOLDING. Participation in the Plan is subject to any minimum required tax withholding on income of the participant in connection with the Plan. Each employee agrees, by entering the Plan, that the Company and its Subsidiaries shall have the right to deduct any such taxes from any payment of any kind otherwise due to the employee, including shares issuable under the Plan. 9

24. NOTIFICATION UPON SALE OF SHARES. Each employee agrees, by entering the Plan, to give the Company prompt notice of any disposition of shares purchased under the Plan where such disposition occurs within two years after the date of grant of the Option pursuant to which such shares were purchased. 25. EFFECTIVE DATE AND APPROVAL OF SHAREHOLDERS. The Plan shall take effect on the first day of the Company's Initial Public Offering, subject to approval by the holders of a majority of the votes cast at a meeting of stockholders at which a quorum is present or by written consent of the stockholders.

(ii) In the event that any dispute, claim or controversy shall not be so resolved by the parties between themselves, Newco and AP Biotech agree that any and all disputes, claims or controversies arising out of or relating to this Agreement or a breach thereof, whether grounded in common law or statutory law, shall be finally settled in accordance with the Arbitration Rules of the International Chamber of Commerce in effect on the Closing Date.

(iii) The number of arbitrators shall be three, chosen in accordance with the procedures set out in this Section 19(d). The award of the arbitrators shall be final and binding on the parties. (iv) Each party shall appoint one arbitrator.

(v) The arbitrators thus appointed shall choose a further arbitrator who will act as the presiding arbitrator of the tribunal. If within (30) days after the appointment of arbitrators under (d)(iv) above, they have not agreed upon the choice of the presiding arbitrator, then at the request of any party to the arbitration proceeding the presiding arbitrator shall be appointed by the appointing authority. (vi) The Chartered Institute of Arbitrators, London, England shall be the appointing authority. (vii) At the request of any party to the arbitration ("requesting party") the arbitrators shall order the other party ("furnishing party") to supply and furnish to the requesting party (the cost of which shall be reimbursed upon demand by the requesting party to the furnishing party) true and complete copies of the Relevant Material and to produce to the arbitral tribunal any or all of the Relevant Material and/or copies thereof as any part or the arbitral tribunal shall require. 28

THE LOCATIONS OF THE OMITTED INFORMATION HAVE BEEN INDICATED WITH ASTERISKS. (viii) The procedures leading to the production of Relevant Material under this paragraph shall be determined by the arbitrators, and may include the preparation of lists of Relevant Material for initial evaluation by the requesting party prior to disclosure and/or inspection of Relevant Material by the requesting party prior to supply and furnishing the copies. In making such determination, the arbitrators shall take into account the urgency with which the Relevant Material should be brought before the arbitral tribunal. (ix) No party shall use or disclose any Relevant Material obtained under this paragraph for any purpose except in the course of the conduct of the arbitration and (as far as applicable) proceedings before any court, and then only to the extent necessary for the implementation and enforcement of any aware of the arbitrators. (x) The arbitration, including the making of the award, shall take place in London, U.K. (xi) All submissions and awards in relation to arbitration hereunder shall be made in English and all arbitration proceedings shall be conducted in English.

The parties to this Agreement hereby acknowledge and agree that the failure of AP Biotech to deposit the Initial Customer Information or any Semi-Annual Customer Information with the Escrow Agent in accordance with the delivery requirements of Section 1A(a) and Section 1A(b) hereof, respectively, will cause irreparable damage to Newco and its businesses and that, accordingly, Newco shall be entitled, if the circumstances so require, to seek the equitable remedy of specific performance to force AP Biotech to deliver such Initial Customer Information or Semi-Annual Customer Information. (e) ASSIGNABILITY; BINDING EFFECT. This Agreement shall be binding upon and inure to the benefit of the parties hereto, their successors and permitted assigns.

In addition to Base Salary, Executive shall be eligible to receive cash incentive compensation as determined by the Board or a Committee thereof from time to time, and shall also be eligible to participate in such incentive compensation plans as the Board or a Committee thereof shall determine from time to time for employees of the same status within the hierarchy of the Company. (b) EXPENSES. Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by him in performing services hereunder during the Period of Employment, in accordance with the policies and procedures then in effect and established by the Company for its senior executive officers. (c) OTHER BENEFITS. During the Period of Employment, Executive shall be entitled to continue to participate in or receive benefits under all of the Company's Employee Benefit Plans in effect on the date hereof, or under plans or arrangements that provide no less favorable treatment to the Executive then the Employee Benefit Plans provided to other members of the Company's senior management. As used herein, the term "Employee Benefit Plans" includes, without limitation, each pension and retirement plan; supplemental pension, retirement and deferred compensation plan; savings and profit-sharing plan; stock ownership plan; stock purchase plan; stock option plan; life insurance plan; medical insurance plan; disability plan; and health and accident plan or arrangement established and maintained by the Company on the date hereof for employees of the same status within the hierarchy of the Company. During the Period of Employment, Executive shall be entitled to an automobile or to a lease for an automobile (the "Company Car") for up to $1,500.00 per month and the cost of automobile insurance for such Company Car. To the extent that the scope or nature of benefits described in this section is determined under the policies of the Company based in whole or in part on the seniority or tenure of an employee's service, Executive shall be deemed to have a tenure with the Company equal to the actual time of Executive's service with the Company. During the Period of Employment, Executive shall be entitled to participate in or receive benefits under any employee benefit plan or arrangement which may, in the future, be made available by the Company to its executives and key management employees, subject to and on a basis consistent with the terms, conditions and overall administration of such plan or arrangement. Any payments or benefits payable to Executive under a plan or arrangement referred to in this Subparagraph 3(c) in respect of any calendar year during which Executive is employed by the Company for less than the whole of such year shall, unless otherwise provided in the applicable plan or arrangement, be prorated in accordance with the number of days in such calendar year during which he is so employed. Should any such payments or benefits accrue on a fiscal (rather than calendar) year, then the proration in the preceding sentence shall be on the basis of a fiscal year rather than calendar year. 2

(d) VACATIONS. Executive shall be entitled to [_______(___)] paid vacation days in each calendar year, which shall be accrued ratably during the calendar year. Executive shall also be entitled to all paid holidays given by the Company to its executives. To the extent that the scope or nature of benefits described in this section are determined under the policies of the Company based in whole or in part on the seniority or tenure of an employee's service, Executive shall be deemed to have a tenure with the Company equal to the actual time of Executive's service with Company. 4. UNAUTHORIZED DISCLOSURE. (a) CONFIDENTIAL INFORMATION. Executive acknowledges that in the course of his employment with the Company (and, if applicable, its predecessors), he has been allowed to become, and will continue to be allowed to become, acquainted with the Company's business affairs, information, trade secrets, and other matters which are of a proprietary or confidential nature, including but not limited to the Company's and its affiliates' and predecessors' operations, business opportunities, price and cost information, finance, customer information, business plans, various sales techniques, manuals, letters, notebooks, procedures, reports, products, processes, services, and other confidential information and knowledge (collectively the "Confidential Information") concerning the Company's and its affiliates' and predecessors' business. The Company agrees to provide on an ongoing basis such Confidential Information as the Company deems necessary or desirable to aid Executive in the performance of his duties. Executive understands and acknowledges that such Confidential Information is confidential, and he agrees not to disclose such Confidential Information to anyone outside the Company except to the extent that (i) Executive deems such disclosure or use reasonably necessary or appropriate in connection with performing his duties on behalf of the Company; (ii) Executive is required by order of a court of competent jurisdiction (by subpoena or similar process) to disclose or discuss any Confidential Information, provided that in such case, Executive shall promptly inform the Company of such event, shall cooperate with the Company in attempting to obtain a protective order or to otherwise restrict such disclosure, and shall only disclose Confidential Information to the minimum extent necessary to comply with any such court order; (iii) such Confidential Information becomes generally known to and available for use in the Company's industry (the "laboratory analytical instruments industry"), other than as a result of any action or inaction by Executive; or (iv) such information has been rightfully received by a member of the laboratory analytical instruments industry or has been published in a form generally available to the laboratory analytical instruments industry prior to the date Executive proposes to disclose or use such information. Executive further agrees that he will not during employment and/or at any time thereafter use such Confidential Information in competing, directly or indirectly, with the Company. At such time as Executive shall cease to be employed by the Company, he will immediately turn over to the Company all Confidential Information, including papers, documents, writings, electronically stored information, other property, and all copies of them provided to or created by him during the course of his employment with the Company. 3

(b) HEIRS, SUCCESSORS, AND LEGAL REPRESENTATIVES. The foregoing provisions of this Paragraph 4 shall be binding upon Executive's heirs, successors, and legal representatives. The provisions of this Paragraph 4 shall survive the termination of this Agreement for any reason. 5. COVENANT NOT TO COMPETE. In consideration for Executive's employment by the Company under the terms provided in this Agreement and as a means to aid in the performance and enforcement of the terms of the provisions of Paragraph 4, Executive agrees that (a) during the term of Executive's employment with the Company and for a period of twelve (12) months thereafter, regardless of the reason for termination of employment, Executive will not, directly or indirectly, as an owner, director, principal, agent, officer, employee, partner, consultant, servant, or otherwise, carry on, operate, manage, control, or become involved in any manner with any business, operation, corporation, partnership, association, agency, or other person or entity which is engaged in a business that produces products that compete directly with any of the Company's products which are produced by the Company or any affiliate of the Company or which the Company or any affiliate of the Company has active plans to produce as of the date of Executive's termination of employment with the Company, in any area or territory in which the Company or any affiliate of the Company conducts or has active plans to conduct operations as of the date of the Executive's termination of employment with the Company; provided, however, that the foregoing shall not prohibit Executive from owning up to one percent (1%) of the outstanding stock of a publicly held company engaged in the laboratory analytical instruments industry; and (b) during the term of Executive's employment with the Company and for a period of twelve (12) months thereafter, regardless of the reason for termination of employment, Executive will not directly or indirectly solicit or induce any present or future employee of the Company or any affiliate of the Company to accept employment with Executive or with any business, operation, corporation, partnership, association, agency, or other person or entity with which Executive may be associated, and Executive will not hire or employ or cause any business, operation, corporation, partnership, association, agency, or other person or entity with which Executive may be associated to hire or employ any present or future employee of the Company. Should Executive violate any of the provisions of this Paragraph, then in addition to all other rights and remedies available to the Company at law or in equity, the duration of this covenant shall automatically be extended for the period of time from which Executive began such violation until he permanently ceases such violation. 6. TERMINATION. Executive's employment hereunder may be terminated without any breach of this Agreement under the following circumstances: (a) DEATH. Executive's employment hereunder shall terminate upon his death. (b) DISABILITY. If, as a result of Executive's incapacity due to physical or mental illness, Executive shall have been absent from his duties hereunder on a full-time basis for one 4

hundred eighty (180) calendar days in the aggregate in any twelve (12) month period, the Company may terminate Executive's employment hereunder. (c) TERMINATION BY COMPANY FOR CAUSE. At any time during the Period of Employment, the Company may terminate Executive's employment hereunder for Cause if such termination is approved by not less than a majority of the Board at a meeting of the Board called and held for such purpose. For purposes of this Agreement, "Cause" shall mean: (A) conduct by Executive constituting a material act of willful misconduct in connection with the performance of his duties, including, without limitation, misappropriation of funds or property of the Company or any of its affiliates other than the occasional, customary and de minimis use of Company property for personal purposes; (B) criminal or civil conviction of Executive, a plea of nolo contendere by Executive or conduct by Executive that would reasonably be expected to result in material injury to the reputation of the Company if he were retained in his position with the Company, including, without limitation, conviction of a felony involving moral turpitude; (C) continued, willful and deliberate non-performance by Executive of his duties hereunder (other than by reason of Executive's physical or mental illness, incapacity or disability) which has continued for more than thirty (30) days following written notice of such non-performance from the Board; (D) a breach by Executive of any of the provisions contained in Paragraphs 4 and 5 of this Agreement; or (E) a violation by Executive of the Company's employment policies which has continued following written notice of such violation from the Board. (d) TERMINATION WITHOUT CAUSE. At any time during the Period of Employment, the Company may terminate Executive's employment hereunder without Cause if such termination is approved by a majority of the Board at a meeting of the Board called and held for such purpose. Any termination by the Company of Executive's employment under this Agreement which does not constitute a termination for Cause under Subparagraph 6(c) or result from the death or disability of the Executive under Subparagraph 6(a) or (b) shall be deemed a termination without Cause. If the Company provides notice to Executive under Paragraph 1 that it does not wish to extend the Period of Employment, such action shall be deemed a termination without Cause. (e) TERMINATION BY EXECUTIVE. At any time during the Period of Employment, Executive may terminate his employment hereunder for any reason, including but not limited to Good Reason. If Executive provides notice to the Company under Paragraph 1 that he does not wish to extend the Period of Employment, such action shall be deemed a voluntary termination by Executive and one without Good Reason. For purposes of this Agreement, "Good Reason" shall mean that Executive has complied with the "Good Reason Process" (hereinafter defined) following the occurrence of any of the following events: (A) a substantial diminution or other substantive adverse change, not consented to by Executive, in the nature or scope of Executive's responsibilities, authorities, powers, functions or duties; (B) any removal, during the Period of Employment, from Executive of his title of Chief Executive Officer; (C) an involuntary reduction in Executive's Base Salary except for across-the-board reductions similarly affecting all or substantially all management employees; (D) a breach by the Company of any of its other material obligations under this Agreement and the failure of the Company to cure such breach 5

within thirty (30) days after written notice thereof by Executive; (E) the involuntary relocation of the Company's offices at which Executive is principally employed or the involuntary relocation of the offices of Executive's primary workgroup to a location more than 30 miles from such offices, or the requirement by the Company that Executive be based anywhere other than the Company's offices at such location on an extended basis, except for required travel on the Company's business to an extent substantially consistent with Executive's business travel obligations; or (F) the failure of the Company to obtain the agreement from any successor to the Company to assume and agree to perform this Agreement as required by Paragraph 10. "Good Reason Process" shall mean that (i) Executive reasonably determines in good faith that a "Good Reason" event has occurred; (ii) Executive notifies the Company in writing of the occurrence of the Good Reason event; (iii) Executive cooperates in good faith with the Company's efforts, for a period not less than ninety (90) days following such notice, to modify Executive's employment situation in a manner acceptable to Executive and Company; and (iv) notwithstanding such efforts, one or more of the Good Reason events continues to exist and has not been modified in a manner acceptable to Executive. If the Company cures the Good Reason event in a manner acceptable to Executive during the ninety (90) day period, Good Reason shall be deemed not to have occurred. (f) NOTICE OF TERMINATION. Except for termination as specified in Subparagraph 6(a), any termination of Executive's employment by the Company or any such termination by Executive shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon. (g) DATE OF TERMINATION. "Date of Termination" shall mean: (A) if Executive's employment is terminated by his death, the date of his death; (B) if Executive's employment is terminated on account of disability under Subparagraph 6(b) or by the Company for Cause under Subparagraph 6(c), the date on which Notice of Termination is given; (C) if Executive's employment is terminated by the Company under Subparagraph 6(d), sixty (60) days after the date on which a Notice of Termination is given; and (D) if Executive's employment is terminated by Executive under Subparagraph 6(e), thirty (30) days after the date on which a Notice of Termination is given. 7. COMPENSATION UPON TERMINATION OR DURING DISABILITY. (a) DEATH. If Executive's employment terminates by reason of his death, the Company shall, within ninety (90) days of death, pay in a lump sum amount to such person as Executive shall designate in a notice filed with the Company or, if no such person is designated, to Executive's estate, Executive's accrued and unpaid Base Salary to the date of his death, plus his accrued and unpaid incentive compensation, if any, under Subparagraph 3(a). Upon the death of Executive, all unvested stock options shall immediately vest in Executive's estate or other legal representatives and become exercisable. All other stock-based grants and awards held by Executive shall vest or be canceled upon the death of Executive in accordance with their terms. For a period of one (1) year following the Date of Termination, the Company shall pay such 6

health insurance premiums as may be necessary to allow Executive's spouse and dependents to receive health insurance coverage substantially similar to coverage they received prior to the Date of Termination. In addition to the foregoing, any payments to which Executive's spouse, beneficiaries, or estate may be entitled under any employee benefit plan shall also be paid in accordance with the terms of such plan or arrangement. Such payments, in the aggregate, shall fully discharge the Company's obligations hereunder. (b) DISABILITY. During any period that Executive fails to perform his duties hereunder as a result of incapacity due to physical or mental illness, Executive shall continue to receive his accrued and unpaid Base Salary and accrued and unpaid incentive compensation, if any, under Subparagraph 3(a), until Executive's employment is terminated due to disability in accordance with Subparagraph 6(b) or until Executive terminates his employment in accordance with Subparagraph 6(e), whichever first occurs. Upon the Date of Termination, all unvested stock options shall immediately vest and become exercisable. All other stock-based grants and awards held by Executive shall vest or be canceled upon the Date of Termination in accordance with their terms. For a period of one (1) year following the Date of Termination, the Company shall pay such health insurance premiums as may be necessary to allow Executive and Executive's spouse and dependents to receive health insurance coverage substantially similar to coverage they received prior to the Date of Termination. Upon termination due to death prior to the termination first to occur as specified in the preceding sentence, Subparagraph 7(a) shall apply. (c) TERMINATION OTHER THAN FOR GOOD REASON. If Executive's employment is terminated by Executive other than for Good Reason as provided in Subparagraph 6(e), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given. Thereafter, the Company shall have no further obligations to Executive except as otherwise expressly provided under this Agreement, provided any such termination shall not adversely affect or alter Executive's rights under any employee benefit plan of the Company in which Executive, at the Date of Termination, has a vested interest, unless otherwise provided in such employee benefit plan or any agreement or other instrument attendant thereto. In addition, all vested but unexercised stock options held by Executive as of the Date of Termination must be exercised by Executive within three (3) months following the Date of Termination or by the end of the option term, if earlier. All other stock-based grants and awards held by Executive shall vest or be canceled upon the Date of Termination in accordance with their terms. (d) TERMINATION FOR GOOD REASON. If Executive terminates his employment for Good Reason as provided in Subparagraph 6(e) or if Executive's employment is terminated by the Company without Cause as provided in Subparagraph 6(d), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given and his accrued and unpaid incentive compensation, if any, under Subparagraph 3(a). In addition, subject to signing by Executive of a general release of claims in a form and manner satisfactory to the Company, 7

(i) the Company shall pay Executive an amount equal to two (2) times the sum of Executive's Average Base Salary and his Average Incentive Compensation (the "Severance Amount"). The Severance Amount shall be paid out in substantially equal bi-weekly installments over twelve (12) months, in arrears or in a lump sum. For purposes of this Agreement, "Average Base Salary" shall mean the average of the annual Base Salary received by Executive for each of the three (3) immediately preceding fiscal years or such fewer number of complete fiscal years as Executive may have been employed by the Company or the amount of Base Salary for the prior fiscal year, whichever is higher. For purposes of this Agreement, "Average Incentive Compensation" shall mean the average of the annual incentive compensation under Subparagraph 3(a) received by Executive for the three (3) immediately preceding fiscal years or such fewer number of complete fiscal years as Executive may have been employed by the Company or the amount of incentive compensation for the prior fiscal year, whichever is higher. In no event shall "Average Incentive Compensation" include any sign-on bonus, retention bonus or any other special bonus. Notwithstanding the foregoing, if the Executive breaches any of the provisions contained in Paragraphs 4 and 5 of this Agreement, all payments of the Severance Amount shall immediately cease. Furthermore, in the event Executive terminates his employment for Good Reason as provided in Subparagraph 6(e), he shall be entitled to the Severance Amount only if he provides the Notice of Termination provided for in Subparagraph 6(f) within thirty (30) days after the occurrence of the event or events which constitute such Good Reason as specified in clauses (A), (B), (C), (D) and (E) of Subparagraph 6(e); and (ii) upon the Date of Termination, each unvested stock option that would otherwise vest during the next twenty-four (24) months shall accelerate and immediately vest. All other stock-based grants and awards held by Executive that would otherwise vest during the next twenty-four (24) months shall accelerate and immediately vest upon the Date of Termination; and (iii) in addition to any other benefits to which Executive may be entitled in accordance with the Company's then existing severance policies, the Company shall, for a period of one (1) year commencing on the Date of Termination, pay such health insurance premiums as may be necessary to allow Executive and Executive's spouse and dependents to continue to receive health insurance coverage. (e) TERMINATION FOR CAUSE. If Executive's employment is terminated by the Company for Cause as provided in Subparagraph 6(c), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given. Thereafter, the Company shall have no further obligations to Executive except as otherwise expressly provided under this Agreement, provided any such termination shall not adversely affect or alter Executive's rights under any employee benefit plan of the Company in which Executive, at the Date of Termination, has a vested interest, unless otherwise provided in such employee benefit plan or any agreement or other instrument attendant thereto. In addition, all stock options held by Executive as of the Date of Termination shall 8

immediately terminate and be of no further force and effect, and all other stock-based grants and awards shall be canceled or terminated in accordance with their terms. (f) Nothing contained in the foregoing Subparagraphs 7(a) through 7(e) shall be construed so as to affect Executive's rights or the Company's obligations relating to agreements or benefits which are unrelated to termination of employment. 8. CHANGE IN CONTROL PAYMENT. The provisions of this Paragraph 8 set forth certain terms of an agreement reached between Executive and the Company regarding Executive's rights and obligations upon the occurrence of a Change in Control of the Company. These provisions are intended to assure and encourage in advance Executive's continued attention and dedication to his assigned duties and his objectivity during the pendency and after the occurrence of any such event. These provisions shall apply in lieu of, and expressly supersede, the provisions of Subparagraph 7(d)(i) regarding severance pay upon a termination of employment, if such termination of employment occurs within eighteen (18) months after the occurrence of the first event constituting a Change of Control, provided that such first event occurs during the Period of Employment. These provisions shall terminate and be of no further force or effect beginning eighteen (18) months after the occurrence of a Change of Control. (a) CHANGE IN CONTROL. (i) If within eighteen (18) months after the occurrence of the first event constituting a Change in Control, Executive's employment is terminated by the Company without Cause as provided in Subparagraph 6(d) or Executive terminates his employment for Good Reason as provided in Subparagraph 6(e), then the Company shall pay Executive a lump sum in cash in an amount equal to three (3) times the sum of (A) Executive's current or most recent Base Salary plus (B) Executive's most recent annual incentive compensation under Subparagraph 3(a) for the most recent fiscal year, excluding any sign-on bonus, retention bonus or any other special bonus; and (ii) Notwithstanding anything to the contrary in any applicable option agreement or stock-based award agreement, upon a Change in Control, all stock options and other stock-based awards granted to Executive by the Company shall immediately accelerate and become exercisable or non-forfeitable as of the effective date of such Change in Control. Executive shall also be entitled to any other rights and benefits with respect to stock-related awards, to the extent and upon the terms provided in the employee stock option or incentive plan or any agreement or other instrument attendant thereto pursuant to which such options or awards were granted; and (iii) The Company shall, for a period of one (1) year commencing on the Date of Termination, pay such health insurance premiums as may be necessary to allow Executive, Executive's spouse and dependents to continue to receive health insurance coverage substantially similar to the coverage they received prior to the Date of Termination. 9

(b) GROSS UP PAYMENT. (i) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any compensation, payment or distribution by the Company to or for the benefit of Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the "Severance Payments"), would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), or any interest or penalties are incurred by Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then Executive shall be entitled to receive an additional payment (a "Gross-Up Payment") such that the net amount retained by Executive, after deduction of any Excise Tax on the Severance Payments, any Federal, state, and local income tax, employment tax and Excise Tax upon the payment provided by this subsection, and any interest and/or penalties assessed with respect to such Excise Tax, shall be equal to the Severance Payments. (ii) Subject to the provisions of Subparagraph 8(b)(iii), all determinations required to be made under this Subparagraph 8(b)(ii), including whether a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall be made by KPMG LLP or any other nationally recognized accounting firm selected by the Company (the "Accounting Firm"), which shall provide detailed supporting calculations both to the Company and Executive within fifteen (15) business days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or Executive. For purposes of determining the amount of the Gross-Up Payment, Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the Gross-Up Payment is to be made, and state and local income taxes at the highest marginal rates of individual taxation in the state and locality of Executive's residence on the Date of Termination, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. The initial Gross-Up Payment, if any, as determined pursuant to this Subparagraph 8(b)(iii), shall be paid to Executive within five (5) days of the receipt of the Accounting Firm's determination. Any determination by the Accounting Firm shall be binding upon the Company and Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (an "Underpayment"). In the event that the Company exhausts its remedies pursuant to Subparagraph 8(b)(iii) and Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred, consistent with the calculations required to be made hereunder, and any such Underpayment, and any interest and penalties imposed on the Underpayment and required to be paid by 10

Executive in connection with the proceedings described in Subparagraph 8(b)(iii), shall be promptly paid by the Company to or for the benefit of Executive. (iii) Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after Executive knows of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which he gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim, provided that the Company has set aside adequate reserves to cover the Underpayment and any interest and penalties thereon that may accrue, Executive shall: (A) give the Company any information reasonably requested by the Company relating to such claim, (B) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney selected by the Company, (C) cooperate with the Company in good faith in order to effectively contest such claim, and (D) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax, including interest and penalties with respect thereto, imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Subparagraph 8(b)(iii), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to Executive on 11

an interest-free basis and shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax, including interest or penalties with respect thereto, imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company's control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and Executive shall be entitled to settle or contest, as the case may be, any other issues raised by the Internal Revenue Service or any other taxing authority. (iv) If, after the receipt by Executive of an amount advanced by the Company pursuant to Subparagraph 8(b)(iii), Executive becomes entitled to receive any refund with respect to such claim, Executive shall (subject to the Company's complying with the requirements of Subparagraph 8(b)(iii)) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by Executive of an amount advanced by the Company pursuant to Subparagraph 8(b)(iii), a determination is made that Executive shall not be entitled to any refund with respect to such claim and the Company does not notify Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. (c) DEFINITIONS. For purposes of this Paragraph 8, the following terms shall have the following meanings: "CHANGE IN CONTROL" shall mean any of the following: (a) any "person," as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the "Act") (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all "affiliates" and "associates" (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the "beneficial owner" (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing twenty-five percent (25%) or more of either (A) the combined voting power of the Company's then outstanding securities having the right to vote in an election of the Company's Board ("Voting Securities") or (B) the then outstanding shares of Company's common stock, par value $0.01 per share ("Common Stock") (other than as a result of an acquisition of securities directly from the Company); or 12

(b) persons who, as of the Commencement Date, constitute the Company's Board (the "Incumbent Directors") cease for any reason, including, without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of the Board, provided that any person becoming a director of the Company subsequent to the Commencement Date shall be considered an Incumbent Director if such person's election was approved by or such person was nominated for election by a vote of at least a majority of the Incumbent Directors; but provided further, that any such person whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of members of the Board or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board, including by reason of agreement intended to avoid or settle any such actual or threatened contest or solicitation, shall not be considered an Incumbent Director; or (c) the stockholders of the Company shall approve (A) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than fifty percent (50%) of the voting shares of the Company issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), (B) any sale, lease, exchange or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company or (C) any plan or proposal for the liquidation or dissolution of the Company. Notwithstanding the foregoing, a "Change of Control" shall not be deemed to have occurred for purposes of the foregoing clause (a) solely as the result of an acquisition of securities by the Company which, by reducing the number of shares of Common Stock or other Voting Securities outstanding, increases the proportionate number of shares beneficially owned by any person to twenty-five percent (25%) or more of either (A) the combined voting power of all of the then outstanding Voting Securities or (B) Common Stock; PROVIDED, HOWEVER, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities or Common Stock (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns twenty-five percent (25%) or more of either (A) the combined voting power of all of the then outstanding Voting Securities or (B) Common Stock, then a "Change of Control" shall be deemed to have occurred for purposes of the foregoing clause (a). 9.

Failure of the Company to obtain an assumption of this Agreement at or prior to the effectiveness of any succession shall be a breach of this Agreement and shall constitute Good Reason if the Executive elects to terminate employment. 11. MISCELLANEOUS.

The invalid portion of this Agreement, if any, shall be modified by any court having jurisdiction to the extent necessary to render such portion enforceable. 13. COUNTERPARTS. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument. 14. ARBITRATION; OTHER DISPUTES. In the event of any dispute or controversy arising under or in connection with this Agreement, the parties shall first promptly try in good faith to settle such dispute or controversy by mediation under the applicable rules of the American Arbitration Association before resorting to arbitration.

Notwithstanding the above, the Company shall be entitled to seek a restraining order or injunction in any court of competent jurisdiction to prevent any continuation of any violation of Paragraph 4 or 5 hereof. Furthermore, should a dispute occur concerning Executive's mental or physical capacity as described in Subparagraph 6(b), 6(c) or 7(b), a doctor selected by Executive and a doctor selected by the Company shall be entitled to examine Executive.

THIRD-PARTY AGREEMENTS AND RIGHTS. Executive represents to the Company that Executive's execution of this Agreement, Executive's employment with the Company and the performance of Executive's proposed duties for the Company will not violate any obligations Executive may have to any employer or other party, and Executive will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging to or obtained from any such previous employment or other party. 16. LITIGATION AND REGULATORY COOPERATION. During and after Executive's employment, Executive shall reasonably cooperate with the Company in the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that transpired while Executive was employed by the Company; provided, however, that such cooperation shall not materially and adversely affect Executive or expose Executive to an increased probability of civil or criminal litigation.

For purposes of this Agreement the "Company" shall refer to the Company and any of its predecessors. WHEREAS, the Company desires to employ Executive and Executive desires to be employed by the Company on the terms contained herein. NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: 1. EMPLOYMENT. The term of this Agreement shall extend from [__________________] (the "Commencement Date") until the second anniversary of the Commencement Date; provided, however, that the term of this Agreement shall automatically be extended for two additional years on each second anniversary of the Commencement Date unless, not less than 90 days prior to each such date, either party shall have given notice to the other that it does not wish to extend this Agreement; provided, further, that if a Change in Control occurs during the original or extended term of this Agreement, the term of this Agreement shall, notwithstanding anything in this sentence to the contrary, continue in effect for a period of not less than eighteen (18) months beyond the month in which the Change in Control occurred. The term of this Agreement shall be subject to termination as provided in Paragraph 6 and may be referred to herein as the "Period of Employment." 2. POSITION AND DUTIES. During the Period of Employment, Executive shall serve as the President and member of the Board of Directors of the Company and shall have such powers and duties as may from time to time be prescribed by the Board of Directors (the "Board") or the Chief Executive Officer of the Company, provided that such duties are consistent with Executive's position or other positions that he may hold from time to time. Executive shall devote his full working time and efforts to the business and affairs of the Company. Notwithstanding the foregoing, Executive may serve on other boards of directors, with the approval of the Board, or engage in religious, charitable or other community activities as long as such services and activities are disclosed to the Board and do not materially interfere with Executive's performance of his duties to the Company as provided in this Agreement. 3. COMPENSATION AND RELATED MATTERS. (a) BASE SALARY AND INCENTIVE COMPENSATION. Executive's initial annual base salary shall be Two Hundred Twenty-Five Thousand ($225,000) Dollars. Executive's base salary shall be redetermined annually by the Board or a Committee thereof. The base salary in effect at any

given time is referred to herein as "Base Salary." The Base Salary shall be payable in substantially equal bi-weekly installments. In addition to Base Salary, Executive shall be eligible to receive cash incentive compensation as determined by the Board or a Committee thereof from time to time, and shall also be eligible to participate in such incentive compensation plans as the Board or a Committee thereof shall determine from time to time for employees of the same status within the hierarchy of the Company. (b) EXPENSES. Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by him in performing services hereunder during the Period of Employment, in accordance with the policies and procedures then in effect and established by the Company for its senior executive officers. (c) OTHER BENEFITS. During the Period of Employment, Executive shall be entitled to continue to participate in or receive benefits under all of the Company's Employee Benefit Plans in effect on the date hereof, or under plans or arrangements that provide no less favorable treatment to the Executive then the Employee Benefit Plans provided to other members of the Company's senior management. As used herein, the term "Employee Benefit Plans" includes, without limitation, each pension and retirement plan; supplemental pension, retirement and deferred compensation plan; savings and profit-sharing plan; stock ownership plan; stock purchase plan; stock option plan; life insurance plan; medical insurance plan; disability plan; and health and accident plan or arrangement established and maintained by the Company on the date hereof for employees of the same status within the hierarchy of the Company. During the Period of Employment, Executive shall be entitled to an automobile or to a lease for an automobile (the "Company Car") for up to $1,500.00 per month and the cost of automobile insurance for such Company Car. To the extent that the scope or nature of benefits described in this section is determined under the policies of the Company based in whole or in part on the seniority or tenure of an employee's service, Executive shall be deemed to have a tenure with the Company equal to the actual time of Executive's service with the Company. During the Period of Employment, Executive shall be entitled to participate in or receive benefits under any employee benefit plan or arrangement which may, in the future, be made available by the Company to its executives and key management employees, subject to and on a basis consistent with the terms, conditions and overall administration of such plan or arrangement. Any payments or benefits payable to Executive under a plan or arrangement referred to in this Subparagraph 3(c) in respect of any calendar year during which Executive is employed by the Company for less than the whole of such year shall, unless otherwise provided in the applicable plan or arrangement, be prorated in accordance with the number of days in such calendar year during which he is so employed. Should any such payments or benefits accrue on a fiscal (rather than calendar) year, then the proration in the preceding sentence shall be on the basis of a fiscal year rather than calendar year. (d) VACATIONS. Executive shall be entitled to [_______(___)] paid vacation days in each calendar year, which shall be accrued ratably during the calendar year. Executive shall also be entitled to all paid holidays given by the Company to its executives. To the extent that the scope or nature of benefits described in this section are determined under the policies of the Company based in whole or in part on the seniority or tenure of an employee's service, Executive 2

shall be deemed to have a tenure with the Company equal to the actual time of Executive's service with Company. 4. UNAUTHORIZED DISCLOSURE. (a) CONFIDENTIAL INFORMATION. Executive acknowledges that in the course of his employment with the Company (and, if applicable, its predecessors), he has been allowed to become, and will continue to be allowed to become, acquainted with the Company's business affairs, information, trade secrets, and other matters which are of a proprietary or confidential nature, including but not limited to the Company's and its affiliates' and predecessors' operations, business opportunities, price and cost information, finance, customer information, business plans, various sales techniques, manuals, letters, notebooks, procedures, reports, products, processes, services, and other confidential information and knowledge (collectively the "Confidential Information") concerning the Company's and its affiliates' and predecessors' business. The Company agrees to provide on an ongoing basis such Confidential Information as the Company deems necessary or desirable to aid Executive in the performance of his duties. Executive understands and acknowledges that such Confidential Information is confidential, and he agrees not to disclose such Confidential Information to anyone outside the Company except to the extent that (i) Executive deems such disclosure or use reasonably necessary or appropriate in connection with performing his duties on behalf of the Company; (ii) Executive is required by order of a court of competent jurisdiction (by subpoena or similar process) to disclose or discuss any Confidential Information, provided that in such case, Executive shall promptly inform the Company of such event, shall cooperate with the Company in attempting to obtain a protective order or to otherwise restrict such disclosure, and shall only disclose Confidential Information to the minimum extent necessary to comply with any such court order; (iii) such Confidential Information becomes generally known to and available for use in the Company's industry (the "laboratory analytical instruments industry"), other than as a result of any action or inaction by Executive; or (iv) such information has been rightfully received by a member of the laboratory analytical instruments industry or has been published in a form generally available to the laboratory analytical instruments industry prior to the date Executive proposes to disclose or use such information. Executive further agrees that he will not during employment and/or at any time thereafter use such Confidential Information in competing, directly or indirectly, with the Company. At such time as Executive shall cease to be employed by the Company, he will immediately turn over to the Company all Confidential Information, including papers, documents, writings, electronically stored information, other property, and all copies of them provided to or created by him during the course of his employment with the Company. (b) HEIRS, SUCCESSORS, AND LEGAL REPRESENTATIVES. The foregoing provisions of this Paragraph 4 shall be binding upon Executive's heirs, successors, and legal representatives. The provisions of this Paragraph 4 shall survive the termination of this Agreement for any reason. 5. COVENANT NOT TO COMPETE. In consideration for Executive's employment by the Company under the terms provided in this Agreement and as a means to aid in the performance and enforcement of the terms of the provisions of Paragraph 4, Executive agrees that 3

(a) during the term of Executive's employment with the Company and for a period of twelve (12) months thereafter, regardless of the reason for termination of employment, Executive will not, directly or indirectly, as an owner, director, principal, agent, officer, employee, partner, consultant, servant, or otherwise, carry on, operate, manage, control, or become involved in any manner with any business, operation, corporation, partnership, association, agency, or other person or entity which is engaged in a business that produces products that compete directly with any of the Company's products which are produced by the Company or any affiliate of the Company or which the Company or any affiliate of the Company has active plans to produce as of the date of Executive's termination of employment with the Company, in any area or territory in which the Company or any affiliate of the Company conducts or has active plans to conduct operations as of the date of the Executive's termination of employment with the Company; provided, however, that the foregoing shall not prohibit Executive from owning up to one percent (1%) of the outstanding stock of a publicly held company engaged in the laboratory analytical instruments industry; and (b) during the term of Executive's employment with the Company and for a period of twelve (12) months thereafter, regardless of the reason for termination of employment, Executive will not directly or indirectly solicit or induce any present or future employee of the Company or any affiliate of the Company to accept employment with Executive or with any business, operation, corporation, partnership, association, agency, or other person or entity with which Executive may be associated, and Executive will not hire or employ or cause any business, operation, corporation, partnership, association, agency, or other person or entity with which Executive may be associated to hire or employ any present or future employee of the Company. Should Executive violate any of the provisions of this Paragraph, then in addition to all other rights and remedies available to the Company at law or in equity, the duration of this covenant shall automatically be extended for the period of time from which Executive began such violation until he permanently ceases such violation. 6. TERMINATION. Executive's employment hereunder may be terminated without any breach of this Agreement under the following circumstances: (a) DEATH. Executive's employment hereunder shall terminate upon his death. (b) DISABILITY. If, as a result of Executive's incapacity due to physical or mental illness, Executive shall have been absent from his duties hereunder on a full-time basis for one hundred eighty (180) calendar days in the aggregate in any twelve (12) month period, the Company may terminate Executive's employment hereunder. (c) TERMINATION BY COMPANY FOR CAUSE. At any time during the Period of Employment, the Company may terminate Executive's employment hereunder for Cause if such termination is approved by not less than a majority of the Board at a meeting of the Board called and held for such purpose. For purposes of this Agreement, "Cause" shall mean: (A) conduct by Executive constituting a material act of willful misconduct in connection with the performance of 4

his duties, including, without limitation, misappropriation of funds or property of the Company or any of its affiliates other than the occasional, customary and de minimis use of Company property for personal purposes; (B) criminal or civil conviction of Executive, a plea of nolo contendere by Executive or conduct by Executive that would reasonably be expected to result in material injury to the reputation of the Company if he were retained in his position with the Company, including, without limitation, conviction of a felony involving moral turpitude; (C) continued, willful and deliberate non-performance by Executive of his duties hereunder (other than by reason of Executive's physical or mental illness, incapacity or disability) which has continued for more than thirty (30) days following written notice of such non-performance from the Board; (D) a breach by Executive of any of the provisions contained in Paragraphs 4 and 5 of this Agreement; or (E) a violation by Executive of the Company's employment policies which has continued following written notice of such violation from the Board. (d) TERMINATION WITHOUT CAUSE. At any time during the Period of Employment, the Company may terminate Executive's employment hereunder without Cause if such termination is approved by a majority of the Board at a meeting of the Board called and held for such purpose. Any termination by the Company of Executive's employment under this Agreement which does not constitute a termination for Cause under Subparagraph 6(c) or result from the death or disability of the Executive under Subparagraph 6(a) or (b) shall be deemed a termination without Cause. If the Company provides notice to Executive under Paragraph 1 that it does not wish to extend the Period of Employment, such action shall be deemed a termination without Cause. (e) TERMINATION BY EXECUTIVE. At any time during the Period of Employment, Executive may terminate his employment hereunder for any reason, including but not limited to Good Reason. If Executive provides notice to the Company under Paragraph 1 that he does not wish to extend the Period of Employment, such action shall be deemed a voluntary termination by Executive and one without Good Reason. For purposes of this Agreement, "Good Reason" shall mean that Executive has complied with the "Good Reason Process" (hereinafter defined) following the occurrence of any of the following events: (A) a substantial diminution or other substantive adverse change, not consented to by Executive, in the nature or scope of Executive's responsibilities, authorities, powers, functions or duties; (B) any removal, during the Period of Employment, from Executive of his title of President; (C) an involuntary reduction in Executive's Base Salary except for across-the-board reductions similarly affecting all or substantially all management employees; (D) a breach by the Company of any of its other material obligations under this Agreement and the failure of the Company to cure such breach within thirty (30) days after written notice thereof by Executive; (E) the involuntary relocation of the Company's offices at which Executive is principally employed or the involuntary relocation of the offices of Executive's primary workgroup to a location more than 30 miles from such offices, or the requirement by the Company that Executive be based anywhere other than the Company's offices at such location on an extended basis, except for required travel on the Company's business to an extent substantially consistent with Executive's business travel obligations; or (F) the failure of the Company to obtain the agreement from any successor to the Company to assume and agree to perform this Agreement as required by Paragraph 10. "Good Reason Process" shall mean that (i) Executive reasonably determines in good faith that a "Good Reason" event has occurred; (ii) 5

Executive notifies the Company in writing of the occurrence of the Good Reason event; (iii) Executive cooperates in good faith with the Company's efforts, for a period not less than ninety (90) days following such notice, to modify Executive's employment situation in a manner acceptable to Executive and Company; and (iv) notwithstanding such efforts, one or more of the Good Reason events continues to exist and has not been modified in a manner acceptable to Executive. If the Company cures the Good Reason event in a manner acceptable to Executive during the ninety (90) day period, Good Reason shall be deemed not to have occurred. (f) NOTICE OF TERMINATION. Except for termination as specified in Subparagraph 6(a), any termination of Executive's employment by the Company or any such termination by Executive shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon. (g) DATE OF TERMINATION. "Date of Termination" shall mean: (A) if Executive's employment is terminated by his death, the date of his death; (B) if Executive's employment is terminated on account of disability under Subparagraph 6(b) or by the Company for Cause under Subparagraph 6(c), the date on which Notice of Termination is given; (C) if Executive's employment is terminated by the Company under Subparagraph 6(d), sixty (60) days after the date on which a Notice of Termination is given; and (D) if Executive's employment is terminated by Executive under Subparagraph 6(e), thirty (30) days after the date on which a Notice of Termination is given. 7. COMPENSATION UPON TERMINATION OR DURING DISABILITY. (a) DEATH. If Executive's employment terminates by reason of his death, the Company shall, within ninety (90) days of death, pay in a lump sum amount to such person as Executive shall designate in a notice filed with the Company or, if no such person is designated, to Executive's estate, Executive's accrued and unpaid Base Salary to the date of his death, plus his accrued and unpaid incentive compensation, if any, under Subparagraph 3(a). Upon the death of Executive, all unvested stock options shall immediately vest in Executive's estate or other legal representatives and become exercisable. All other stock-based grants and awards held by Executive shall vest or be canceled upon the death of Executive in accordance with their terms. For a period of one (1) year following the Date of Termination, the Company shall pay such health insurance premiums as may be necessary to allow Executive's spouse and dependents to receive health insurance coverage substantially similar to coverage they received prior to the Date of Termination. In addition to the foregoing, any payments to which Executive's spouse, beneficiaries, or estate may be entitled under any employee benefit plan shall also be paid in accordance with the terms of such plan or arrangement. Such payments, in the aggregate, shall fully discharge the Company's obligations hereunder. (b) DISABILITY. During any period that Executive fails to perform his duties hereunder as a result of incapacity due to physical or mental illness, Executive shall continue to receive his accrued and unpaid Base Salary and accrued and unpaid incentive compensation, if 6

any, under Subparagraph 3(a), until Executive's employment is terminated due to disability in accordance with Subparagraph 6(b) or until Executive terminates his employment in accordance with Subparagraph 6(e), whichever first occurs. Upon the Date of Termination, all unvested stock options shall immediately vest and become exercisable. All other stock-based grants and awards held by Executive shall vest or be canceled upon the Date of Termination in accordance with their terms. For a period of one (1) year following the Date of Termination, the Company shall pay such health insurance premiums as may be necessary to allow Executive and Executive's spouse and dependents to receive health insurance coverage substantially similar to coverage they received prior to the Date of Termination. Upon termination due to death prior to the termination first to occur as specified in the preceding sentence, Subparagraph 7(a) shall apply. (c) TERMINATION OTHER THAN FOR GOOD REASON. If Executive's employment is terminated by Executive other than for Good Reason as provided in Subparagraph 6(e), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given. Thereafter, the Company shall have no further obligations to Executive except as otherwise expressly provided under this Agreement, provided any such termination shall not adversely affect or alter Executive's rights under any employee benefit plan of the Company in which Executive, at the Date of Termination, has a vested interest, unless otherwise provided in such employee benefit plan or any agreement or other instrument attendant thereto. In addition, all vested but unexercised stock options held by Executive as of the Date of Termination must be exercised by Executive within three (3) months following the Date of Termination or by the end of the option term, if earlier. All other stock-based grants and awards held by Executive shall vest or be canceled upon the Date of Termination in accordance with their terms. (d) TERMINATION FOR GOOD REASON. If Executive terminates his employment for Good Reason as provided in Subparagraph 6(e) or if Executive's employment is terminated by the Company without Cause as provided in Subparagraph 6(d), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given and his accrued and unpaid incentive compensation, if any, under Subparagraph 3(a). In addition, subject to signing by Executive of a general release of claims in a form and manner satisfactory to the Company, (i) the Company shall pay Executive an amount equal to two (2) times the sum of Executive's Average Base Salary and his Average Incentive Compensation (the "Severance Amount"). The Severance Amount shall be paid out in substantially equal bi-weekly installments over twelve (12) months, in arrears or in a lump sum. For purposes of this Agreement, "Average Base Salary" shall mean the average of the annual Base Salary received by Executive for each of the three (3) immediately preceding fiscal years or such fewer number of complete fiscal years as Executive may have been employed by the Company or the amount of Base Salary for the prior fiscal year, whichever is higher. For purposes of this Agreement, "Average Incentive Compensation" shall mean the average of the annual incentive compensation under Subparagraph 3(a) received by 7

Executive for the three (3) immediately preceding fiscal years or such fewer number of complete fiscal years as Executive may have been employed by the Company or the amount of incentive compensation for the prior fiscal year, whichever is higher. In no event shall "Average Incentive Compensation" include any sign-on bonus, retention bonus or any other special bonus. Notwithstanding the foregoing, if the Executive breaches any of the provisions contained in Paragraphs 4 and 5 of this Agreement, all payments of the Severance Amount shall immediately cease. Furthermore, in the event Executive terminates his employment for Good Reason as provided in Subparagraph 6(e), he shall be entitled to the Severance Amount only if he provides the Notice of Termination provided for in Subparagraph 6(f) within thirty (30) days after the occurrence of the event or events which constitute such Good Reason as specified in clauses (A), (B), (C), (D) and (E) of Subparagraph 6(e); and (ii) upon the Date of Termination, each unvested stock option that would otherwise vest during the next twenty-four (24) months shall accelerate and immediately vest. All other stock-based grants and awards held by Executive that would otherwise vest during the next twenty-four (24) months shall accelerate and immediately vest upon the Date of Termination; and (iii) in addition to any other benefits to which Executive may be entitled in accordance with the Company's then existing severance policies, the Company shall, for a period of one (1) year commencing on the Date of Termination, pay such health insurance premiums as may be necessary to allow Executive and Executive's spouse and dependents to continue to receive health insurance coverage. (e) TERMINATION FOR CAUSE. If Executive's employment is terminated by the Company for Cause as provided in Subparagraph 6(c), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given. Thereafter, the Company shall have no further obligations to Executive except as otherwise expressly provided under this Agreement, provided any such termination shall not adversely affect or alter Executive's rights under any employee benefit plan of the Company in which Executive, at the Date of Termination, has a vested interest, unless otherwise provided in such employee benefit plan or any agreement or other instrument attendant thereto. In addition, all stock options held by Executive as of the Date of Termination shall immediately terminate and be of no further force and effect, and all other stock-based grants and awards shall be canceled or terminated in accordance with their terms. (f) Nothing contained in the foregoing Subparagraphs 7(a) through 7(e) shall be construed so as to affect Executive's rights or the Company's obligations relating to agreements or benefits which are unrelated to termination of employment. 8. CHANGE IN CONTROL PAYMENT. The provisions of this Paragraph 8 set forth certain terms of an agreement reached between Executive and the Company regarding Executive's rights and obligations upon the occurrence of a Change in Control of the Company. These provisions are 8

intended to assure and encourage in advance Executive's continued attention and dedication to his assigned duties and his objectivity during the pendency and after the occurrence of any such event. These provisions shall apply in lieu of, and expressly supersede, the provisions of Subparagraph 7(d)(i) regarding severance pay upon a termination of employment, if such termination of employment occurs within eighteen (18) months after the occurrence of the first event constituting a Change of Control, provided that such first event occurs during the Period of Employment. These provisions shall terminate and be of no further force or effect beginning eighteen (18) months after the occurrence of a Change of Control. (a) CHANGE IN CONTROL. (i) If within eighteen (18) months after the occurrence of the first event constituting a Change in Control, Executive's employment is terminated by the Company without Cause as provided in Subparagraph 6(d) or Executive terminates his employment for Good Reason as provided in Subparagraph 6(e), then the Company shall pay Executive a lump sum in cash in an amount equal to three (3) times the sum of (A) Executive's current or most recent Base Salary plus (B) Executive's most recent annual incentive compensation under Subparagraph 3(a) for the most recent fiscal year, excluding any sign-on bonus, retention bonus or any other special bonus; and (ii) Notwithstanding anything to the contrary in any applicable option agreement or stock-based award agreement, upon a Change in Control, all stock options and other stock-based awards granted to Executive by the Company shall immediately accelerate and become exercisable or non-forfeitable as of the effective date of such Change in Control. Executive shall also be entitled to any other rights and benefits with respect to stock-related awards, to the extent and upon the terms provided in the employee stock option or incentive plan or any agreement or other instrument attendant thereto pursuant to which such options or awards were granted; and (iii) The Company shall, for a period of one (1) year commencing on the Date of Termination, pay such health insurance premiums as may be necessary to allow Executive, Executive's spouse and dependents to continue to receive health insurance coverage substantially similar to the coverage they received prior to the Date of Termination. (b) GROSS UP PAYMENT. (i) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any compensation, payment or distribution by the Company to or for the benefit of Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the "Severance Payments"), would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), or any interest or penalties are incurred by Executive with respect to such excise tax (such excise tax, together with 9

any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then Executive shall be entitled to receive an additional payment (a "Gross-Up Payment") such that the net amount retained by Executive, after deduction of any Excise Tax on the Severance Payments, any Federal, state, and local income tax, employment tax and Excise Tax upon the payment provided by this subsection, and any interest and/or penalties assessed with respect to such Excise Tax, shall be equal to the Severance Payments. (ii) Subject to the provisions of Subparagraph 8(b)(iii), all determinations required to be made under this Subparagraph 8(b)(ii), including whether a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall be made by KPMG LLP or any other nationally recognized accounting firm selected by the Company (the "Accounting Firm"), which shall provide detailed supporting calculations both to the Company and Executive within fifteen (15) business days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or Executive. For purposes of determining the amount of the Gross-Up Payment, Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the Gross-Up Payment is to be made, and state and local income taxes at the highest marginal rates of individual taxation in the state and locality of Executive's residence on the Date of Termination, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. The initial Gross-Up Payment, if any, as determined pursuant to this Subparagraph 8(b)(iii), shall be paid to Executive within five (5) days of the receipt of the Accounting Firm's determination. Any determination by the Accounting Firm shall be binding upon the Company and Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (an "Underpayment"). In the event that the Company exhausts its remedies pursuant to Subparagraph 8(b)(iii) and Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred, consistent with the calculations required to be made hereunder, and any such Underpayment, and any interest and penalties imposed on the Underpayment and required to be paid by Executive in connection with the proceedings described in Subparagraph 8(b)(iii), shall be promptly paid by the Company to or for the benefit of Executive. (iii) Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after Executive knows of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which he gives such notice to the Company 10

(or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim, provided that the Company has set aside adequate reserves to cover the Underpayment and any interest and penalties thereon that may accrue, Executive shall: (A) give the Company any information reasonably requested by the Company relating to such claim, (B) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney selected by the Company, (C) cooperate with the Company in good faith in order to effectively contest such claim, and (D) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax, including interest and penalties with respect thereto, imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Subparagraph 8(b)(iii), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to Executive on an interest-free basis and shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax, including interest or penalties with respect thereto, imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company's control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and 11

Executive shall be entitled to settle or contest, as the case may be, any other issues raised by the Internal Revenue Service or any other taxing authority. (iv) If, after the receipt by Executive of an amount advanced by the Company pursuant to Subparagraph 8(b)(iii), Executive becomes entitled to receive any refund with respect to such claim, Executive shall (subject to the Company's complying with the requirements of Subparagraph 8(b)(iii)) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by Executive of an amount advanced by the Company pursuant to Subparagraph 8(b)(iii), a determination is made that Executive shall not be entitled to any refund with respect to such claim and the Company does not notify Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. (c) DEFINITIONS. For purposes of this Paragraph 8, the following terms shall have the following meanings: "CHANGE IN CONTROL" shall mean any of the following: (a) any "person," as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the "Act") (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all "affiliates" and "associates" (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the "beneficial owner" (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing twenty-five percent (25%) or more of either (A) the combined voting power of the Company's then outstanding securities having the right to vote in an election of the Company's Board ("Voting Securities") or (B) the then outstanding shares of Company's common stock, par value $0.01 per share ("Common Stock") (other than as a result of an acquisition of securities directly from the Company); or (b) persons who, as of the Commencement Date, constitute the Company's Board (the "Incumbent Directors") cease for any reason, including, without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of the Board, provided that any person becoming a director of the Company subsequent to the Commencement Date shall be considered an Incumbent Director if such person's election was approved by or such person was nominated for election by a vote of at least a majority of the Incumbent Directors; but provided further, that any such person whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of members of the Board or other actual or threatened solicitation of proxies or consents by or on behalf of a person other 12

than the Board, including by reason of agreement intended to avoid or settle any such actual or threatened contest or solicitation, shall not be considered an Incumbent Director; or (c) the stockholders of the Company shall approve (A) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than fifty percent (50%) of the voting shares of the Company issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), (B) any sale, lease, exchange or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company or (C) any plan or proposal for the liquidation or dissolution of the Company. Notwithstanding the foregoing, a "Change of Control" shall not be deemed to have occurred for purposes of the foregoing clause (a) solely as the result of an acquisition of securities by the Company which, by reducing the number of shares of Common Stock or other Voting Securities outstanding, increases the proportionate number of shares beneficially owned by any person to twenty-five percent (25%) or more of either (A) the combined voting power of all of the then outstanding Voting Securities or (B) Common Stock; PROVIDED, HOWEVER, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities or Common Stock (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns twenty-five percent (25%) or more of either (A) the combined voting power of all of the then outstanding Voting Securities or (B) Common Stock, then a "Change of Control" shall be deemed to have occurred for purposes of the foregoing clause (a). 9.

The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and agree to perform this Agreement to the same extent that the Company would be required to perform it if no succession had taken place. Failure of the Company to obtain an assumption of this Agreement at or prior to the effectiveness of any succession shall be a breach of this Agreement and shall constitute Good Reason if the Executive elects to terminate employment. 11. MISCELLANEOUS. No provisions of this Agreement may be modified, waived, or discharged unless such waiver, modification, or discharge is agreed to in writing and signed by Executive and such officer of the Company as may be specifically designated by the Board. No waiver by either party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.

VALIDITY. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

Judgment may be entered on the arbitrator's award in any court having jurisdiction. Notwithstanding the above, the Company shall be entitled to seek a restraining order or injunction in any court of competent jurisdiction to prevent any continuation of any violation of Paragraph 4 or 5 hereof. Furthermore, should a dispute occur concerning Executive's mental or physical capacity as described in Subparagraph 6(b), 6(c) or 7(b), a doctor selected by Executive and a doctor selected by the Company shall be entitled to examine Executive. If the opinion of the Company's doctor and Executive's doctor conflict, the Company's doctor and Executive's doctor shall together agree upon a third doctor, whose opinion shall be binding. 15. THIRD-PARTY AGREEMENTS AND RIGHTS. Executive represents to the Company that Executive's execution of this Agreement, Executive's employment with the Company and the performance of Executive's proposed duties for the Company will not violate any obligations Executive may have to any employer or other party, and Executive will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging to or obtained from any such previous employment or other party. 16.

During and after Executive's employment, Executive also shall cooperate fully with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while Executive was employed by the Company. The Company shall also provide Executive with compensation on an hourly basis at a rate of $120.71 for requested litigation and regulatory cooperation that occurs after his termination of employment, and reimburse Executive for all costs and expenses incurred in connection with his performance under this Paragraph 16, including, but not limited to, reasonable attorneys' fees and costs. 15

For purposes of this Agreement the "Company" shall refer to the Company and any of its predecessors. WHEREAS, the Company desires to employ Executive and Executive desires to be employed by the Company on the terms contained herein. NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows: 1. EMPLOYMENT. The term of this Agreement shall extend from [__________________] (the "Commencement Date") until the first anniversary of the Commencement Date; provided, however, that the term of this Agreement shall automatically be extended for one additional year on each anniversary of the Commencement Date unless, not less than 90 days prior to each such date, either party shall have given notice to the other that it does not wish to extend this Agreement; provided, further, that if a Change in Control occurs during the original or extended term of this Agreement, the term of this Agreement shall, notwithstanding anything in this sentence to the contrary, continue in effect for a period of not less than eighteen (18) months beyond the month in which the Change in Control occurred. The term of this Agreement shall be subject to termination as provided in Paragraph 6 and may be referred to herein as the "Period of Employment." 2. POSITION AND DUTIES. During the Period of Employment, Executive shall serve as the Chief Financial Officer and shall have such powers and duties as may from time to time be prescribed by the Board of Directors (the "Board") or the Chief Executive Officer of the Company, provided that such duties are consistent with Executive's position or other positions that he may hold from time to time. Executive shall devote his full working time and efforts to the business and affairs of the Company. Notwithstanding the foregoing, Executive may serve on other boards of directors, with the approval of the Board, or engage in religious, charitable or other community activities as long as such services and activities are disclosed to the Board and do not materially interfere with Executive's performance of his duties to the Company as provided in this Agreement. 3. COMPENSATION AND RELATED MATTERS. (a) BASE SALARY AND INCENTIVE COMPENSATION. Executive's initial annual base salary shall be One Hundred Eighty-Five Thousand ($185,000) Dollars. Executive's base salary shall be redetermined annually by the Board or a Committee thereof. The base salary in effect at any

given time is referred to herein as "Base Salary." The Base Salary shall be payable in substantially equal bi-weekly installments. In addition to Base Salary, Executive shall be eligible to receive cash incentive compensation as determined by the Board or a Committee thereof from time to time, and shall also be eligible to participate in such incentive compensation plans as the Board or a Committee thereof shall determine from time to time for employees of the same status within the hierarchy of the Company. (b) EXPENSES. Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by him in performing services hereunder during the Period of Employment, in accordance with the policies and procedures then in effect and established by the Company for its senior executive officers. (c) OTHER BENEFITS. During the Period of Employment, Executive shall be entitled to continue to participate in or receive benefits under all of the Company's Employee Benefit Plans in effect on the date hereof, or under plans or arrangements that provide no less favorable treatment to the Executive then the Employee Benefit Plans provided to other members of the Company's senior management.

To the extent that the scope or nature of benefits described in this section is determined under the policies of the Company based in whole or in part on the seniority or tenure of an employee's service, Executive shall be deemed to have a tenure with the Company equal to the actual time of Executive's service with the Company. During the Period of Employment, Executive shall be entitled to participate in or receive benefits under any employee benefit plan or arrangement which may, in the future, be made available by the Company to its executives and key management employees, subject to and on a basis consistent with the terms, conditions and overall administration of such plan or arrangement. Any payments or benefits payable to Executive under a plan or arrangement referred to in this Subparagraph 3(c) in respect of any calendar year during which Executive is employed by the Company for less than the whole of such year shall, unless otherwise provided in the applicable plan or arrangement, be prorated in accordance with the number of days in such calendar year during which he is so employed. Should any such payments or benefits accrue on a fiscal (rather than calendar) year, then the proration in the preceding sentence shall be on the basis of a fiscal year rather than calendar year. (d) VACATIONS. Executive shall be entitled to [_______(___)] paid vacation days in each calendar year, which shall be accrued ratably during the calendar year. Executive shall also be entitled to all paid holidays given by the Company to its executives. To the extent that the scope or nature of benefits described in this section are determined under the policies of the Company based in whole or in part on the seniority or tenure of an employee's service, Executive shall be deemed to have a tenure with the Company equal to the actual time of Executive's service with Company. 2

4. UNAUTHORIZED DISCLOSURE. (a) CONFIDENTIAL INFORMATION. Executive acknowledges that in the course of his employment with the Company (and, if applicable, its predecessors), he has been allowed to become, and will continue to be allowed to become, acquainted with the Company's business affairs, information, trade secrets, and other matters which are of a proprietary or confidential nature, including but not limited to the Company's and its affiliates' and predecessors' operations, business opportunities, price and cost information, finance, customer information, business plans, various sales techniques, manuals, letters, notebooks, procedures, reports, products, processes, services, and other confidential information and knowledge (collectively the "Confidential Information") concerning the Company's and its affiliates' and predecessors' business. The Company agrees to provide on an ongoing basis such Confidential Information as the Company deems necessary or desirable to aid Executive in the performance of his duties. Executive understands and acknowledges that such Confidential Information is confidential, and he agrees not to disclose such Confidential Information to anyone outside the Company except to the extent that (i) Executive deems such disclosure or use reasonably necessary or appropriate in connection with performing his duties on behalf of the Company; (ii) Executive is required by order of a court of competent jurisdiction (by subpoena or similar process) to disclose or discuss any Confidential Information, provided that in such case, Executive shall promptly inform the Company of such event, shall cooperate with the Company in attempting to obtain a protective order or to otherwise restrict such disclosure, and shall only disclose Confidential Information to the minimum extent necessary to comply with any such court order; (iii) such Confidential Information becomes generally known to and available for use in the Company's industry (the "laboratory analytical instruments industry"), other than as a result of any action or inaction by Executive; or (iv) such information has been rightfully received by a member of the laboratory analytical instruments industry or has been published in a form generally available to the laboratory analytical instruments industry prior to the date Executive proposes to disclose or use such information. Executive further agrees that he will not during employment and/or at any time thereafter use such Confidential Information in competing, directly or indirectly, with the Company. At such time as Executive shall cease to be employed by the Company, he will immediately turn over to the Company all Confidential Information, including papers, documents, writings, electronically stored information, other property, and all copies of them provided to or created by him during the course of his employment with the Company. (b) HEIRS, SUCCESSORS, AND LEGAL REPRESENTATIVES. The foregoing provisions of this Paragraph 4 shall be binding upon Executive's heirs, successors, and legal representatives. The provisions of this Paragraph 4 shall survive the termination of this Agreement for any reason. 5. COVENANT NOT TO COMPETE. In consideration for Executive's employment by the Company under the terms provided in this Agreement and as a means to aid in the performance and enforcement of the terms of the provisions of Paragraph 4, Executive agrees that (a) during the term of Executive's employment with the Company and for a period of twelve (12) months thereafter, regardless of the reason for termination of employment, Executive 3

will not, directly or indirectly, as an owner, director, principal, agent, officer, employee, partner, consultant, servant, or otherwise, carry on, operate, manage, control, or become involved in any manner with any business, operation, corporation, partnership, association, agency, or other person or entity which is engaged in a business that produces products that compete directly with any of the Company's products which are produced by the Company or any affiliate of the Company or which the Company or any affiliate of the Company has active plans to produce as of the date of Executive's termination of employment with the Company, in any area or territory in which the Company or any affiliate of the Company conducts or has active plans to conduct operations as of the date of the Executive's termination of employment with the Company; provided, however, that the foregoing shall not prohibit Executive from owning up to one percent (1%) of the outstanding stock of a publicly held company engaged in the laboratory analytical instruments industry; and (b) during the term of Executive's employment with the Company and for a period of twelve (12) months thereafter, regardless of the reason for termination of employment, Executive will not directly or indirectly solicit or induce any present or future employee of the Company or any affiliate of the Company to accept employment with Executive or with any business, operation, corporation, partnership, association, agency, or other person or entity with which Executive may be associated, and Executive will not hire or employ or cause any business, operation, corporation, partnership, association, agency, or other person or entity with which Executive may be associated to hire or employ any present or future employee of the Company. Should Executive violate any of the provisions of this Paragraph, then in addition to all other rights and remedies available to the Company at law or in equity, the duration of this covenant shall automatically be extended for the period of time from which Executive began such violation until he permanently ceases such violation. 6. TERMINATION. Executive's employment hereunder may be terminated without any breach of this Agreement under the following circumstances: (a) DEATH. Executive's employment hereunder shall terminate upon his death. (b) DISABILITY. If, as a result of Executive's incapacity due to physical or mental illness, Executive shall have been absent from his duties hereunder on a full-time basis for one hundred eighty (180) calendar days in the aggregate in any twelve (12) month period, the Company may terminate Executive's employment hereunder. (c) TERMINATION BY COMPANY FOR CAUSE. At any time during the Period of Employment, the Company may terminate Executive's employment hereunder for Cause if such termination is approved by not less than a majority of the Board at a meeting of the Board called and held for such purpose. For purposes of this Agreement, "Cause" shall mean: (A) conduct by Executive constituting a material act of willful misconduct in connection with the performance of his duties, including, without limitation, misappropriation of funds or property of the Company or any of its affiliates other than the occasional, customary and de minimis use of Company 4

property for personal purposes; (B) criminal or civil conviction of Executive, a plea of nolo contendere by Executive or conduct by Executive that would reasonably be expected to result in material injury to the reputation of the Company if he were retained in his position with the Company, including, without limitation, conviction of a felony involving moral turpitude; (C) continued, willful and deliberate non-performance by Executive of his duties hereunder (other than by reason of Executive's physical or mental illness, incapacity or disability) which has continued for more than thirty (30) days following written notice of such non-performance from the Board; (D) a breach by Executive of any of the provisions contained in Paragraphs 4 and 5 of this Agreement; or (E) a violation by Executive of the Company's employment policies which has continued following written notice of such violation from the Board. (d) TERMINATION WITHOUT CAUSE. At any time during the Period of Employment, the Company may terminate Executive's employment hereunder without Cause if such termination is approved by a majority of the Board at a meeting of the Board called and held for such purpose. Any termination by the Company of Executive's employment under this Agreement which does not constitute a termination for Cause under Subparagraph 6(c) or result from the death or disability of the Executive under Subparagraph 6(a) or (b) shall be deemed a termination without Cause. If the Company provides notice to Executive under Paragraph 1 that it does not wish to extend the Period of Employment, such action shall be deemed a termination without Cause. (e) TERMINATION BY EXECUTIVE. At any time during the Period of Employment, Executive may terminate his employment hereunder for any reason, including but not limited to Good Reason. If Executive provides notice to the Company under Paragraph 1 that he does not wish to extend the Period of Employment, such action shall be deemed a voluntary termination by Executive and one without Good Reason. For purposes of this Agreement, "Good Reason" shall mean that Executive has complied with the "Good Reason Process" (hereinafter defined) following the occurrence of any of the following events: (A) a substantial diminution or other substantive adverse change, not consented to by Executive, in the nature or scope of Executive's responsibilities, authorities, powers, functions or duties; (B) any removal, during the Period of Employment, from Executive of his title of Chief Financial Officer; (C) an involuntary reduction in Executive's Base Salary except for across-the-board reductions similarly affecting all or substantially all management employees; (D) a breach by the Company of any of its other material obligations under this Agreement and the failure of the Company to cure such breach within thirty (30) days after written notice thereof by Executive; (E) the involuntary relocation of the Company's offices at which Executive is principally employed or the involuntary relocation of the offices of Executive's primary workgroup to a location more than 30 miles from such offices, or the requirement by the Company that Executive be based anywhere other than the Company's offices at such location on an extended basis, except for required travel on the Company's business to an extent substantially consistent with Executive's business travel obligations; or (F) the failure of the Company to obtain the agreement from any successor to the Company to assume and agree to perform this Agreement as required by Paragraph 10. "Good Reason Process" shall mean that (i) Executive reasonably determines in good faith that a "Good Reason" event has occurred; (ii) Executive notifies the Company in writing of the occurrence of 5

the Good Reason event; (iii) Executive cooperates in good faith with the Company's efforts, for a period not less than ninety (90) days following such notice, to modify Executive's employment situation in a manner acceptable to Executive and Company; and (iv) notwithstanding such efforts, one or more of the Good Reason events continues to exist and has not been modified in a manner acceptable to Executive. If the Company cures the Good Reason event in a manner acceptable to Executive during the ninety (90) day period, Good Reason shall be deemed not to have occurred. (f) NOTICE OF TERMINATION. Except for termination as specified in Subparagraph 6(a), any termination of Executive's employment by the Company or any such termination by Executive shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon. (g) DATE OF TERMINATION. "Date of Termination" shall mean: (A) if Executive's employment is terminated by his death, the date of his death; (B) if Executive's employment is terminated on account of disability under Subparagraph 6(b) or by the Company for Cause under Subparagraph 6(c), the date on which Notice of Termination is given; (C) if Executive's employment is terminated by the Company under Subparagraph 6(d), sixty (60) days after the date on which a Notice of Termination is given; and (D) if Executive's employment is terminated by Executive under Subparagraph 6(e), thirty (30) days after the date on which a Notice of Termination is given. 7. COMPENSATION UPON TERMINATION OR DURING DISABILITY. (a) DEATH. If Executive's employment terminates by reason of his death, the Company shall, within ninety (90) days of death, pay in a lump sum amount to such person as Executive shall designate in a notice filed with the Company or, if no such person is designated, to Executive's estate, Executive's accrued and unpaid Base Salary to the date of his death, plus his accrued and unpaid incentive compensation, if any, under Subparagraph 3(a). Upon the death of Executive, all unvested stock options shall immediately vest in Executive's estate or other legal representatives and become exercisable. All other stock-based grants and awards held by Executive shall vest or be canceled upon the death of Executive in accordance with their terms. For a period of one (1) year following the Date of Termination, the Company shall pay such health insurance premiums as may be necessary to allow Executive's spouse and dependents to receive health insurance coverage substantially similar to coverage they received prior to the Date of Termination. In addition to the foregoing, any payments to which Executive's spouse, beneficiaries, or estate may be entitled under any employee benefit plan shall also be paid in accordance with the terms of such plan or arrangement. Such payments, in the aggregate, shall fully discharge the Company's obligations hereunder. (b) DISABILITY. During any period that Executive fails to perform his duties hereunder as a result of incapacity due to physical or mental illness, Executive shall continue to receive his accrued and unpaid Base Salary and accrued and unpaid incentive compensation, if 6

any, under Subparagraph 3(a), until Executive's employment is terminated due to disability in accordance with Subparagraph 6(b) or until Executive terminates his employment in accordance with Subparagraph 6(e), whichever first occurs. Upon the Date of Termination, all unvested stock options shall immediately vest and become exercisable. All other stock-based grants and awards held by Executive shall vest or be canceled upon the Date of Termination in accordance with their terms. For a period of one (1) year following the Date of Termination, the Company shall pay such health insurance premiums as may be necessary to allow Executive and Executive's spouse and dependents to receive health insurance coverage substantially similar to coverage they received prior to the Date of Termination. Upon termination due to death prior to the termination first to occur as specified in the preceding sentence, Subparagraph 7(a) shall apply. (c) TERMINATION OTHER THAN FOR GOOD REASON. If Executive's employment is terminated by Executive other than for Good Reason as provided in Subparagraph 6(e), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given. Thereafter, the Company shall have no further obligations to Executive except as otherwise expressly provided under this Agreement, provided any such termination shall not adversely affect or alter Executive's rights under any employee benefit plan of the Company in which Executive, at the Date of Termination, has a vested interest, unless otherwise provided in such employee benefit plan or any agreement or other instrument attendant thereto. In addition, all vested but unexercised stock options held by Executive as of the Date of Termination must be exercised by Executive within three (3) months following the Date of Termination or by the end of the option term, if earlier. All other stock-based grants and awards held by Executive shall vest or be canceled upon the Date of Termination in accordance with their terms. (d) TERMINATION FOR GOOD REASON. If Executive terminates his employment for Good Reason as provided in Subparagraph 6(e) or if Executive's employment is terminated by the Company without Cause as provided in Subparagraph 6(d), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given and his accrued and unpaid incentive compensation, if any, under Subparagraph 3(a). In addition, subject to signing by Executive of a general release of claims in a form and manner satisfactory to the Company, (i) the Company shall pay Executive an amount equal to the sum of Executive's Average Base Salary and his Average Incentive Compensation (the "Severance Amount"). The Severance Amount shall be paid out in substantially equal bi-weekly installments over twelve (12) months, in arrears or in a lump sum. For purposes of this Agreement, "Average Base Salary" shall mean the average of the annual Base Salary received by Executive for each of the three (3) immediately preceding fiscal years or such fewer number of complete fiscal years as Executive may have been employed by the Company or the amount of Base Salary for the prior fiscal year, whichever is higher. For purposes of this Agreement, "Average Incentive Compensation" shall mean the average of the annual incentive compensation under Subparagraph 3(a) received by 7

Executive for the three (3) immediately preceding fiscal years or such fewer number of complete fiscal years as Executive may have been employed by the Company or the amount of incentive compensation for the prior fiscal year, whichever is higher. In no event shall "Average Incentive Compensation" include any sign-on bonus, retention bonus or any other special bonus. Notwithstanding the foregoing, if the Executive breaches any of the provisions contained in Paragraphs 4 and 5 of this Agreement, all payments of the Severance Amount shall immediately cease. Furthermore, in the event Executive terminates his employment for Good Reason as provided in Subparagraph 6(e), he shall be entitled to the Severance Amount only if he provides the Notice of Termination provided for in Subparagraph 6(f) within thirty (30) days after the occurrence of the event or events which constitute such Good Reason as specified in clauses (A), (B), (C), (D) and (E) of Subparagraph 6(e); and (ii) upon the Date of Termination, each unvested stock option that would otherwise vest during the next twenty-four (24) months shall accelerate and immediately vest. All other stock-based grants and awards held by Executive that would otherwise vest during the next twenty-four (24) months shall accelerate and immediately vest upon the Date of Termination; and (iii) in addition to any other benefits to which Executive may be entitled in accordance with the Company's then existing severance policies, the Company shall, for a period of one (1) year commencing on the Date of Termination, pay such health insurance premiums as may be necessary to allow Executive and Executive's spouse and dependents to continue to receive health insurance coverage. (e) TERMINATION FOR CAUSE. If Executive's employment is terminated by the Company for Cause as provided in Subparagraph 6(c), then the Company shall, through the Date of Termination, pay Executive his accrued and unpaid Base Salary at the rate in effect at the time Notice of Termination is given. Thereafter, the Company shall have no further obligations to Executive except as otherwise expressly provided under this Agreement, provided any such termination shall not adversely affect or alter Executive's rights under any employee benefit plan of the Company in which Executive, at the Date of Termination, has a vested interest, unless otherwise provided in such employee benefit plan or any agreement or other instrument attendant thereto. In addition, all stock options held by Executive as of the Date of Termination shall immediately terminate and be of no further force and effect, and all other stock-based grants and awards shall be canceled or terminated in accordance with their terms. (f) Nothing contained in the foregoing Subparagraphs 7(a) through 7(e) shall be construed so as to affect Executive's rights or the Company's obligations relating to agreements or benefits which are unrelated to termination of employment. 8. CHANGE IN CONTROL PAYMENT. The provisions of this Paragraph 8 set forth certain terms of an agreement reached between Executive and the Company regarding Executive's rights and obligations upon the occurrence of a Change in Control of the Company. These provisions are 8

intended to assure and encourage in advance Executive's continued attention and dedication to his assigned duties and his objectivity during the pendency and after the occurrence of any such event. These provisions shall apply in lieu of, and expressly supersede, the provisions of Subparagraph 7(d)(i) regarding severance pay upon a termination of employment, if such termination of employment occurs within eighteen (18) months after the occurrence of the first event constituting a Change of Control, provided that such first event occurs during the Period of Employment. These provisions shall terminate and be of no further force or effect beginning eighteen (18) months after the occurrence of a Change of Control. (a) CHANGE IN CONTROL. (i) If within eighteen (18) months after the occurrence of the first event constituting a Change in Control, Executive's employment is terminated by the Company without Cause as provided in Subparagraph 6(d) or Executive terminates his employment for Good Reason as provided in Subparagraph 6(e), then the Company shall pay Executive a lump sum in cash in an amount equal to one and a half (1.5) times the sum of (A) Executive's current or most recent Base Salary plus (B) Executive's most recent annual incentive compensation under Subparagraph 3(a) for the most recent fiscal year, excluding any sign-on bonus, retention bonus or any other special bonus; and (ii) Notwithstanding anything to the contrary in any applicable option agreement or stock-based award agreement, upon a Change in Control, all stock options and other stock-based awards granted to Executive by the Company shall immediately accelerate and become exercisable or non-forfeitable as of the effective date of such Change in Control. Executive shall also be entitled to any other rights and benefits with respect to stock-related awards, to the extent and upon the terms provided in the employee stock option or incentive plan or any agreement or other instrument attendant thereto pursuant to which such options or awards were granted; and (iii) The Company shall, for a period of one (1) year commencing on the Date of Termination, pay such health insurance premiums as may be necessary to allow Executive, Executive's spouse and dependents to continue to receive health insurance coverage substantially similar to the coverage they received prior to the Date of Termination. (b) GROSS UP PAYMENT. (i) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any compensation, payment or distribution by the Company to or for the benefit of Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the "Severance Payments"), would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), or any interest or penalties are incurred by Executive with respect to such excise tax (such excise tax, together with 9

any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then Executive shall be entitled to receive an additional payment (a "Gross-Up Payment") such that the net amount retained by Executive, after deduction of any Excise Tax on the Severance Payments, any Federal, state, and local income tax, employment tax and Excise Tax upon the payment provided by this subsection, and any interest and/or penalties assessed with respect to such Excise Tax, shall be equal to the Severance Payments. (ii) Subject to the provisions of Subparagraph 8(b)(iii), all determinations required to be made under this Subparagraph 8(b)(ii), including whether a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall be made by KPMG LLP or any other nationally recognized accounting firm selected by the Company (the "Accounting Firm"), which shall provide detailed supporting calculations both to the Company and Executive within fifteen (15) business days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or Executive. For purposes of determining the amount of the Gross-Up Payment, Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the Gross-Up Payment is to be made, and state and local income taxes at the highest marginal rates of individual taxation in the state and locality of Executive's residence on the Date of Termination, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. The initial Gross-Up Payment, if any, as determined pursuant to this Subparagraph 8(b)(iii), shall be paid to Executive within five (5) days of the receipt of the Accounting Firm's determination. Any determination by the Accounting Firm shall be binding upon the Company and Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (an "Underpayment"). In the event that the Company exhausts its remedies pursuant to Subparagraph 8(b)(iii) and Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred, consistent with the calculations required to be made hereunder, and any such Underpayment, and any interest and penalties imposed on the Underpayment and required to be paid by Executive in connection with the proceedings described in Subparagraph 8(b)(iii), shall be promptly paid by the Company to or for the benefit of Executive. (iii) Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after Executive knows of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which he gives such notice to the Company 10

(or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim, provided that the Company has set aside adequate reserves to cover the Underpayment and any interest and penalties thereon that may accrue, Executive shall: (A) give the Company any information reasonably requested by the Company relating to such claim, (B) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney selected by the Company, (C) cooperate with the Company in good faith in order to effectively contest such claim, and (D) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax, including interest and penalties with respect thereto, imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Subparagraph 8(b)(iii), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to Executive on an interest-free basis and shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax, including interest or penalties with respect thereto, imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company's control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and 11

Executive shall be entitled to settle or contest, as the case may be, any other issues raised by the Internal Revenue Service or any other taxing authority. (iv) If, after the receipt by Executive of an amount advanced by the Company pursuant to Subparagraph 8(b)(iii), Executive becomes entitled to receive any refund with respect to such claim, Executive shall (subject to the Company's complying with the requirements of Subparagraph 8(b)(iii)) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by Executive of an amount advanced by the Company pursuant to Subparagraph 8(b)(iii), a determination is made that Executive shall not be entitled to any refund with respect to such claim and the Company does not notify Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. (c) DEFINITIONS. For purposes of this Paragraph 8, the following terms shall have the following meanings: "CHANGE IN CONTROL" shall mean any of the following: (a) any "person," as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the "Act") (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all "affiliates" and "associates" (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the "beneficial owner" (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing twenty-five percent (25%) or more of either (A) the combined voting power of the Company's then outstanding securities having the right to vote in an election of the Company's Board ("Voting Securities") or (B) the then outstanding shares of Company's common stock, par value $0.01 per share ("Common Stock") (other than as a result of an acquisition of securities directly from the Company); or (b) persons who, as of the Commencement Date, constitute the Company's Board (the "Incumbent Directors") cease for any reason, including, without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of the Board, provided that any person becoming a director of the Company subsequent to the Commencement Date shall be considered an Incumbent Director if such person's election was approved by or such person was nominated for election by a vote of at least a majority of the Incumbent Directors; but provided further, that any such person whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of members of the Board or other actual or threatened solicitation of proxies or consents by or on behalf of a person other 12

than the Board, including by reason of agreement intended to avoid or settle any such actual or threatened contest or solicitation, shall not be considered an Incumbent Director; or (c) the stockholders of the Company shall approve (A) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than fifty percent (50%) of the voting shares of the Company issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), (B) any sale, lease, exchange or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company or (C) any plan or proposal for the liquidation or dissolution of the Company. Notwithstanding the foregoing, a "Change of Control" shall not be deemed to have occurred for purposes of the foregoing clause (a) solely as the result of an acquisition of securities by the Company which, by reducing the number of shares of Common Stock or other Voting Securities outstanding, increases the proportionate number of shares beneficially owned by any person to twenty-five percent (25%) or more of either (A) the combined voting power of all of the then outstanding Voting Securities or (B) Common Stock; PROVIDED, HOWEVER, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities or Common Stock (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns twenty-five percent (25%) or more of either (A) the combined voting power of all of the then outstanding Voting Securities or (B) Common Stock, then a "Change of Control" shall be deemed to have occurred for purposes of the foregoing clause (a). 9.

SUCCESSOR TO COMPANY. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and agree to perform this Agreement to the same extent that the Company would be required to perform it if no succession had taken place. Failure of the Company to obtain an assumption of this Agreement at or prior to the effectiveness of any succession shall be a breach of this Agreement and shall constitute Good Reason if the Executive elects to terminate employment. 11. MISCELLANEOUS. No provisions of this Agreement may be modified, waived, or discharged unless such waiver, modification, or discharge is agreed to in writing and signed by Executive and such officer of the Company as may be specifically designated by the Board. No waiver by either party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, unless specifically referred to herein, with respect to the subject matter hereof have been made by either party which are not set forth expressly in this Agreement. The validity, interpretation, construction, and performance of this Agreement shall be governed by the laws of the Commonwealth of Massachusetts (without regard to principles of conflicts of laws). 12. VALIDITY. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. The invalid portion of this Agreement, if any, shall be modified by any court having jurisdiction to the extent necessary to render such portion enforceable. 14

13. COUNTERPARTS. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument. 14. ARBITRATION; OTHER DISPUTES. In the event of any dispute or controversy arising under or in connection with this Agreement, the parties shall first promptly try in good faith to settle such dispute or controversy by mediation under the applicable rules of the American Arbitration Association before resorting to arbitration.

Judgment may be entered on the arbitrator's award in any court having jurisdiction. Notwithstanding the above, the Company shall be entitled to seek a restraining order or injunction in any court of competent jurisdiction to prevent any continuation of any violation of Paragraph 4 or 5 hereof. Furthermore, should a dispute occur concerning Executive's mental or physical capacity as described in Subparagraph 6(b), 6(c) or 7(b), a doctor selected by Executive and a doctor selected by the Company shall be entitled to examine Executive. If the opinion of the Company's doctor and Executive's doctor conflict, the Company's doctor and Executive's doctor shall together agree upon a third doctor, whose opinion shall be binding. 15. THIRD-PARTY AGREEMENTS AND RIGHTS. Executive represents to the Company that Executive's execution of this Agreement, Executive's employment with the Company and the performance of Executive's proposed duties for the Company will not violate any obligations Executive may have to any employer or other party, and Executive will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging to or obtained from any such previous employment or other party. 16.

Executive's cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times. During and after Executive's employment, Executive also shall cooperate fully with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while Executive was employed by the Company.

LESSEE covenants to pay all rentals when due and payable without any set off, deduction or demand whatsoever. Any reasonable amounts paid or expenses incurred by LESSOR to correct violations of any of the LESSEE's obligations hereunder (following notice to LESSEE of such violations and the expiration without cure of the cure period specified in Article XIX hereof) shall be additional rental. Any additional rental provided for in this Lease becomes due with the next installment of Minimum Rent due after receipt of notice of such additional rental from LESSOR. Rentals and statements required of LESSEE shall be paid or delivered to LESSOR at the place designated for notices to LESSOR. If any payment of rent or additional rent due hereunder is received by LESSOR more than ten (10) days after notice from LESSOR that it is due, then LESSOR may, in addition to any other remedies LESSOR may have for late payment of rent, assess a late charge in the amount of two percent (2%) of the late payment, such late charge to be additional rent under this Lease.

(a) LESSEE shall pay as additional rent for each Tax Year during the term, an amount equal to LESSEE'S Proportionate Share of the Taxes for such Tax Year (the "Tax Payment"). LESSEE shall pay in advance of the first month and each month thereafter an estimate of one twelfth (1/12) of LESSEE's Proportionate Share of taxes which shall be an amount estimated and billed by LESSOR prior to the beginning of each Tax Year. Such estimate and billing may be revised by LESSOR, at LESSOR's sole option, during the Tax Year based on tax bills or assessments actually received by LESSOR relating to the current Tax Year. Within sixty (60) days of the end of each Tax Year LESSOR shall furnish LESSEE, in reasonable detail, the final computation and allocation of taxes for the preceding Tax Year. If the amount allocated to LESSEE exceeds the sum of the estimated taxes already paid by LESSEE, LESSEE shall pay such excess to LESSOR within thirty (30) days of demand therefor. If the amount allocated to LESSEE is less than that already paid by LESSEE, LESSOR shall credit the difference to future payments of Minimum Rent (or pay the same to LESSEE at the end of the term, if no extra Minimum Rent is due). The Tax Payment shall be prorated, if necessary, to correspond with that portion of a Tax Year occurring within the term of this Lease. (b) If LESSOR shall receive a refund for any Tax Year(s) in which a Tax Payment shall have been made by LESSEE, LESSOR shall repay to LESSEE LESSEE'S Proportionate Share of such refund up to the amount of such payment after deducting therefrom the costs and expenses of obtaining such refund, which costs and expenses shall be allocated to all of the Tax Years involved. LESSOR agrees to act in good faith in connection with a determination as to whether the filing of abatement applications affecting the Leased Premises would be appropriate. (c) With respect to any period at the expiration of the term of this Lease, as the same may be extended, which shall constitute a partial Tax Year, LESSOR'S statement shall adjust the amount of the additional rent due hereunder. The obligation of LESSEE in respect to such additional rent applicable for the last year of the term of this Lease as the same may be extended shall survive the expiration of the term of this Lease. 6

For the purpose of this Lease, the term "Tax Year" shall mean the twelve (12) month period established as the real estate tax year by the taxing authorities having lawful jurisdiction over the Industrial Park. 5.3 OPERATING EXPENSES. (a) OPERATING EXPENSES RENT. LESSEE shall pay as additional rent LESSEE's Proportionate Share of the Operating Expenses paid or incurred by LESSOR, provided, however, that during the initial five (5) year term, LESSEE shall not be required to pay more than One Dollar Twenty Five Cents ($1.25) per square foot of the Leased Premises per annum for any of the consecutive twelve (12) month periods which begin on the commencement date of the term and on each anniversary of the commencement date occurring during the initial term. (b) PAYMENT. During December of each calendar year or as soon thereafter as practicable, LESSOR will give LESSEE written notice of its estimate of LESSEE's Proportionate Share of operating Expenses for the ensuing calendar year on or before the first day of each month during the ensuing calendar year, LESSEE will pay to LESSEE One Twelfth (1/12th) of such estimated amounts, provided that if such notice is not given in December, LESSEE will continue to pay on the basis of the prior year's estimate until the month after such notice is given. If at any time or times it appears to LESSOR that the amounts payable for Operating Expenses for the current calendar year will vary from its estimate by more than Ten Percent (10%), LESSOR, by written notice to LESSEE, will revise its estimate for such year, and subsequent payments by LESSEE for such year will be in an amount so that by the end of such year LESSEE will have paid a total sum equal to such revised estimate. LESSOR will indicate in its notice to LESSEE the reasons LESSOR believes its estimate is low or high by more than Ten Percent (10%). (c) STATEMENT. Within ninety (90) days after the close of each calendar year or as soon after such ninety (90) day period as practicable, LESSOR will deliver to LESSEE a statement of amounts of LESSEE's Proportionate Share of operating Expenses payable under this Lease for such calendar year. If such statement shows an amount owing by LESSEE that is more than the estimated payments for such calendar year previously made by LESSEE, LESSEE will pay the deficiency to LESSOR within thirty (30) days after delivery of the statement. If the statement shows an amount which is less than the estimated payments previously paid by LESSEE for the calendar year, provided LESSEE is not then in default, LESSOR will remit the amount owed LESSEE with the statement. LESSEE has the right, exercisable no more than once each calendar year on reasonable notice and at a time reasonably acceptable to LESSOR, to cause an audit to be performed at LESSEE's sole cost and expense of LESSOR's operations and/or books and records pertaining to Operating Expenses and Taxes and Insurance of the preceding calendar year. LESSOR, at LESSOR's sole discretion, may provide such audit prepared by a certified public accountant in lieu of allowing LESSEE to audit LESSOR's operations and/or books. 7

(d) PRORATION. If for any reason other than the default of LESSEE, this Lease terminates on a day other than the last day of a calendar year, the amount of LESSEE's Proportionate Share of Operating Expenses payable by LESSEE applicable to the calendar year in which such termination occurs will be prorated on the basis which the number of days from the commencement of such calendar year to and including such termination date bears to Three Hundred Sixty Five (365). Likewise, in the year this Lease commences, LESSEE's Proportionate Share of Operating Expenses shall be prorated based upon the number of days from the Commencement Date to the end of the calendar year in which the Commencement Date occurs.

Throughout the term hereof, LESSOR shall maintain a policy of insurance on the Building against damage by fire and such other risks covered by the so-called Extended Coverage endorsement.

LESSEE shall procure such insurance on its improvements and personal property as it deems appropriate. 10.3 LESSEE's LIABILITY INSURANCE. LESSEE agrees to maintain with respect to the Leased Premises, Building, and the Industrial Park, broad form comprehensive general liability insurance with limits in the minimum amount of One Million Dollars ($1,000,000.00) per occurrence and property damage liability insurance in the minimum amount of Two Hundred Fifty Thousand Dollars ($250,000.00) per occurrence and to submit copies of such policies and certificates of such insurance to LESSOR.

LESSEE agrees to pay to LESSOR, upon demand, the amount of any extra premiums or any increase in the rate of such insurance which results from LESSEE's occupancy of or conduct in the Leased Premises, whether or not LESSOR has consented to such business.

otherwise furnish services, or for any cause or causes beyond the reasonable control of LESSOR (but LESSOR, in respect of those matters for which LESSOR is responsible, will use reasonable efforts to restore such services or make such repairs as soon as possible), nor in any event for any indirect or consequential damages; and failure or omission on the part of the LESSOR to furnish such service or make such repair under those circumstances and conditions shall not be construed as an eviction of the LESSEE, nor render the LESSOR liable in damages, nor entitle LESSEE to an abatement or rent, nor release the LESSEE from the obligation to fulfill any of the covenants under this Lease. 11.3. CONSTRUCTION. LESSEE acknowledges that LESSOR and/or lessees of the Building, on or after the date hereof , may be making improvements to their Premises, the, Building, or Industrial Park which will require construction work during normal business hours.

LESSEE shall have no right to any abatement of rental or other compensation or to any claim of breach of LESSOR'S covenants under this Lease (provided that there is no significant interruption to LESSEE'S access to the Leased Premises) or for loss of business or inconvenience, or in any event for consequential damages on account of such construction work. ARTICLE XII - CONSTRUCTION AND ALTERATIONS 12.1. Prior to the commencement of the term of this Lease, LESSOR shall substantially complete the work enumerated on Exhibit E attached hereto and made a part hereof and shall have obtained a certificate of occupancy for the Leased Premises. Exhibit E shall define the total scope of work which LESSOR is to perform within the Leased Premises, and, upon the completion of such work, LESSOR shall notify LESSEE that the work has been substantially completed and provide LESSOR with certificates to such effect from LESSOR's architect.

LESSEE shall prepare, at its sole cost and expense, complete plans and specifications prepared by a professional architect or engineer for all LESSEE'S work, whether original or alterations, and submit such plans and specifications to LESSOR or LESSOR'S designated representative for written approval no later than fifteen (15) days, prior to the planned commencement of any work, together with the name of the contractor or contractors to perform such work. All contractors or others performing work on the Leased Premises shall be approved in writing by LESSOR. All such allowed alterations shall be at LESSEE'S expense, shall be in quality at least equal to the contemplated or then existing construction, as the case may be, and shall be prosecuted diligently and completed in a good and workmanlike manner. Any alterations or improvements made by the LESSEE shall become the property of the LESSOR at the termination of occupancy as provided herein; provided, however, that LESSEE shall be obligated to remove such improvements, fixtures and equipment at the said termination of occupancy as LESSOR shall request prior to such termination, the LESSEE being obligated to repair any damage which such removal may cause.

In the event that LESSOR does any of the things it is by this paragraph empowered to do, LESSEE shall promptly reimburse LESSOR for any sums expended by LESSOR in connection therewith, including any sum paid in discharge of any lien or judgement, for premiums on bonds, or for attorney's fees.

ARTICLE XIII - ASSIGNMENT/SUBLEASING LESSEE agrees not to sell, assign, mortgage, pledge, franchise or in any manner transfer this Lease or any estate of interest thereunder and not to sublet the Leased Premises or any part or parts thereof and not to permit any licensee or concessionaire therein without the previous written consent of the LESSOR in each instance first obtained. Consent to a subletting by LESSEE shall not be unreasonably withheld or delayed. Consent by LESSOR to one assignment of this Lease or to one subletting, sale, mortgage, pledge or other transfer including licensing or the grant of a concession shall not be a waiver of LESSOR'S right under this Article as to any subsequent similar action. Notwithstanding any assignment or subletting, LESSEE shall remain fully liable on this Lease and shall not be released from performing any of the terms, covenants and conditions of this Lease. If, any time during the term of this Lease, LESSEE (and/or the guarantor of LESSEE, if any) is a corporation or a trust (whether or not having shares of beneficial interest) and there shall occur any change in the identity of any of the persons then having power to control the election or appointment of the directors, trustees, or other persons exercising like functions and managing the affairs of LESSEE to other than the families of the principals of LESSEE, the same shall be deemed an assignment requiring consent hereunder, and LESSEE shall so notify LESSOR thereof. This section shall not apply if the LESSEE (and/or guarantor, if any) named herein is a corporation and the outstanding voting stock thereof is listed on a recognized securities exchange or is wholly owned by another corporation whose outstanding voting stock is so listed. LESSOR'S rights to assign this Lease are and shall remain unqualified. Upon any bona fide sale of the Leased Premises in an arms length transaction and provided the purchaser agrees to assume all past and future obligations of LESSOR under this Lease, LESSOR shall thereupon and not otherwise be entirely freed of all obligations of the LESSOR hereunder and shall not be subject to any liability resulting from any act or omission or event occurring after such conveyance, except that any covenant or obligation of LESSOR hereunder affecting land owned by LESSOR shall continue for its term during such ownership, but no longer. Upon the sale or other transfer of LESSOR'S interest in this Lease, LESSEE agrees to recognize and attorn to such transferee as LESSOR, and LESSEE further agrees to execute and deliver a recordable instrument setting forth the provisions of this paragraph. ARTICLE XIV - SUBORDINATION This Lease is and shall be subject and subordinate to all ground leases and mortgages of record, any of which may now or hereafter be placed on or affect the Building, the Leased Premises, or any part thereof and to each advance made or to be made under any such mortgages, and to all renewals, modifications, consolidations, replacements and extensions thereof and all substitutions therefor, provided that said mortgagee agrees in writing delivered to LESSEE to recognize this Lease, and not to disturb LESSEE'S rights thereunder. LESSOR shall deliver such a non-disturbance agreement to LESSEE from any mortgage company 15

holding a mortgage covering the Building. In confirmation of such subordination, LESSEE shall execute and deliver promptly any nondisturbance, subordination, and attornment agreement that LESSOR and/or any mortgagee or lessor under any ground or underlying lease and/or their respective successors may require so long as the same is in substance similar to those customarily utilized in the Greater Boston, Massachusetts area. Without limitation of any of the provisions of this Lease, if any ground lessor or mortgagee shall succeed to the interest of LESSOR by reason of the exercise of its rights under such ground lease or mortgage (or the acceptance of voluntary conveyance in lieu thereof) or the expiration or sooner termination of such ground lease, however caused, then such successor shall give written notice to LESSEE (which in the case of a ground lease shall be within thirty (30) days after such expiration or sooner termination) that it is succeeding to the interest of LESSOR under this Lease; and in such event, the LESSEE shall attorn to such successor and shall ipso facto be and become bound directly to such successor in interest to LESSOR to perform and observe all the LESSEE'S obligations under this Lease without the necessity of the execution of any further instrument. Nevertheless, LESSEE agrees at any time and from time to time during the term hereof to execute a suitable instrument in confirmation of LESSEE'S agreement to LESSOR, pr any ground lessor, or such mortgagee, and/or their respective assigns and LESSEE'S attorney-in-fact, to execute and deliver any such agreement of attornment for and on behalf of LESSEE. ARTICLE XV - LESSOR'S ACCESS The LESSOR or agents of the LESSOR may, upon reasonable prior notice, at reasonable times, enter to view the Leased Premises and make repairs and alterations as LESSOR should elect to do and may show the Leased Premises to others, and at any time within six (6) months before the expiration of the term, may, affix to any suitable part of the Leased Premises a notice for selling the Leased Premises or property of which the Leased Premises are a part and keep the same so affixed without hindrance or molestation. LESSOR agrees to make such entries in a manner which will minimize any disruption to LESSEE within the Leased Premises. ARTICLE XVI - INDEMNIFICATION LESSEE hereby covenants to indemnify and save LESSOR harmless from and against any and all claims, liabilities or penalties asserted by or on behalf of any person, firm, corporation or public authority: (a) On account of or based upon any injury to person, or loss of or damage to property sustained or occurring on the Leased Premises on account of or based in whole or in part upon the act, omission, fault, negligence or misconduct of any person other than LESSOR or its employees, or agents after delivery of the Leased Premises to LESSEE; 16

(b) On account of or based in whole or in part upon any injury to person, or loss of or damage to property sustained or occurring in or about the Building or the Industrial Park, arising out of the use or occupancy of the Building or the Leased Premises by the LESSEE or by any person claiming by, through or under LESSEE, in addition to and not in limitation of Section (a) above; (c) on account of or based upon (including monies due on account of) any work or thing whatsoever done (other than by LESSOR or its contractors or agents or employees of either) on the Leased Premises during the term of this Lease, any further time during which LESSEE occupies the Leased Premises and, to the extent resulting from the actions of LESSEE or its servants, agents or contractors, during the time, if any, prior to the commencement date when LESSEE may have been given access to the Leased Premises; and, in respect of any of the foregoing, from and against all costs, expenses (including, without limitation, reasonable attorneys' fees and expenses) and liabilities incurred in or in connection with any such claim or any action or proceeding brought thereon; and in case any action or proceeding be brought against LESSOR, LESSEE shall at LESSEE'S expense resist and defend such action or proceeding and employ counsel therefor reasonably satisfactory to LESSOR, it being agreed that such counsel as may act for LESSEE'S insurance underwriters engaged in defense shall be deemed satisfactory. ARTICLE XVII - WAIVER OF SUBROGATION LESSEE covenants that with respect to any insurance coverage carried by LESSEE in connection with the Leased Premises or the Building or the parcel upon which it is located, (whether or not such insurance is required by the terms of this Lease) such insurance shall provide for the waiver by the insurance carrier of any subrogation rights against LESSOR, its agents, servants and employees. ARTICLE XVIII - DESTRUCTION OF PREMISES/EMINENT DOMAIN 18.1 PARTIAL DESTRUCTION. In the event of a partial destruction of the Premises during the term hereof, from any cause covered by insurance, LESSOR shall repair the same to the extent such repairs can be made with the insurance proceeds made available to LESSOR and within sixty (60) days under then existing governmental laws and regulations. Such partial destruction shall not terminate this Lease and LESSEE shall be entitled to a proportionate reduction of rent based upon the extent to which the LESSEE shall be deprived of productive use of the Premises if such repairs cannot be made within said sixty (60) days period, LESSOR, at its option, may make the repairs within a reasonable time not to exceed one hundred eighty (180) days. If LESSOR elects to make said repairs, this Lease will continue in effect and the rent will be proportionately abated as stated above. If the repairs cannot be made within sixty (60) days with the available insurance proceeds and LESSOR elects not to make said repairs, this Lease may be terminated at the option of either party. 17

18.2 MATERIAL/TOTAL DESTRUCTION. If the Building in which the Premises are situated or the Building and Land sustains damage of more than one third (1/3) of the replacement cost thereof, LESSOR may elect to terminate this Lease whether the Premises are injured or not. If the Premises are damaged significantly enough that in LESSOR's reasonable judgment repair of the damage will take over one hundred eighty (180) days, LESSEE may terminate this Lease. A total destruction of the Building in which the Premises are situated or the Building and Land shall terminate this Lease. 18.3 EMINENT DOMAIN. (a) In the event that a substantial portion of the Leased Premises or the Building or the Land shall be taken or appropriated by eminent domain or shall be condemned for any public or quasi-public use, then this Lease and the term hereof may be terminated at the election of LESSOR by a notice in writing of its election so to terminate, which notice shall be given no later than sixty (60) days following the date on which LESSOR shall have received notice of such taking, appropriation, or condemnation. If the entire Leased Premises or such portion thereof or a substantial portion of the Building or the access thereto shall be so taken, appropriated, or condemned, such that LESSEE shall be precluded from utilizing the Leased Premises substantially as contemplated, then this Lease and the term hereof may be terminated at the election of LESSEE by a notice in writing of its election so to terminate, which notice shall be given no later than sixty (60) days following the date on which LESSEE shall have received notice (clearly stating the effect of such taking upon the Leased Premises and the Industrial Park) of such taking, appropriation or condemnation. Upon the giving of any such notice of termination (either by LESSOR or LESSEE) this Lease and the term hereof shall terminate on or retroactively as of the date on which LESSEE shall be required to vacate any portion of the area so taken, appropriated or condemned or shall be deprived of the means of access thereto or upon ninety (90) days written notice after LESSOR is required to vacate the applicable portion of the Building or the Industrial Park, provided that no portion of the Leased Premises has been taken or condemned. In the event of such termination, this Lease and the term hereof shall expire as of such effective termination date and rent shall be apportioned as of such date. (b) If neither party (having the right to so) elects to terminate this Lease and the term hereof, LESSOR shall, with reasonable diligence and at LESSOR'S expense, restore the remainder of the Leased Premises (but not LESSEE'S personal property or alterations installed at LESSEE'S expense), and the means of access thereto, as nearly as practicable to the condition which obtained prior to such taking, appropriation or condemnation, in which event the rent shall be adjusted such that a just proportion of the rent shall be abated according to the nature and extent of the taking, appropriation or condemnation. LESSOR shall not be liable for any delays in such restoration which are due to acts of God, as defined herein, nor shall LESSOR be liable for any inconvenience or annoyance to LESSEE or injury to LESSEE'S business resulting from reasonable delays in such restoration (although the same shall be taken into account in connection with any abatement of rent). LESSOR expressly reserves and LESSEE hereby assigns to LESSOR, all rights to compensation and damages 18

created, accrued or accruing by reason of any such taking, appropriation or condemnation, excluding only rights to compensation or damages relating to LESSEE'S fixtures, property, or equipment or relocation expenses made directly to LESSEE by a governmental agency or entity. (c) If the Leased Premises or any part thereof or the access thereto shall be taken, appropriated or condemned for any temporary use (i) this Lease shall be and remain unaffected thereby and LESSEE shall continue to pay the full amount of the rent, (ii) LESSEE shall be entitled to receive for itself any award made for such use allocable to the term of this Lease, and (iii) LESSEE shall be responsible for any repairs necessary to restore the Leased Premises to their condition prior to such taking, appropriation or condemnation, provided that if any such taking, appropriation or condemnation extends beyond the term of this Lease, the costs of such repairs shall be allocated between LESSOR and LESSEE in proportion to the amount of any award each receives. Any taking, appropriation or condemnation continuing in excess of six (6) months shall be deemed to be a permanent taking, appropriation or condemnation and shall be governed by Sections (a) and (b) above. ARTICLE XIX - DEFAULT 19.1 If LESSEE shall default in the payment of rent or any other charges due hereunder and such default shall continue for ten (10) days after written notice to LESSEE, or if LESSEE shall default in the performance of any other of its obligations and such default shall continue for thirty (30) days after written notice thereof to the LESSEE (except that if the LESSEE cannot reasonably cure any such default of its other obligations within said thirty (30) day period, this period may be extended for a reasonable time not exceeding ninety (90) days, provided that the LESSEE commences to cure such default within the thirty (30) day period and proceeds diligently thereafter to effect such cure), or if the LESSEE shall file a petition under any bankruptcy or insolvency law, or if such a petition filed against LESSEE is not dismissed within sixty (60) days, or if the LESSEE shall be adjudicated bankrupt or insolvent according to law, or if the LESSEE shall make any assignment for the benefit of creditors, or if the LESSEE shall file any petition seeking a reorganization, arrangement or similar relief, or if a receiver, custodian, trustee or similar agent of the Leased Premises or of all or a substantial part of LESSEE's assets shall be authorized or appointed or if LESSEE's interest in this Lease is taken upon execution or other process of law in any action against LESSEE, then the LESSOR may lawfully enter the Leased Premises and repossess the same as the former estate of the LESSOR, or terminate this Lease by written notice to LESSEE and, in either event, expel the LESSEE and those claiming through or under the LESSEE, and remove their effects (forcibly, if necessary) without being deemed guilty of any manner of trespass and without prejudice to any other remedy which the LESSOR may have for arrears of rent and other charges due hereunder or proceeding on account of breach of covenant, and upon entry or notice as aforesaid, this Lease shall terminate. LESSEE covenants, in case of any default by LESSEE hereunder (which covenant shall survive the termination of this Lease), to pay LESSOR all costs of enforcing its rights under this Lease (including, without limitation, reasonable attorney's fees and expenses), reletting expenses, expenses incurred putting the 19

Leased Premises in good order and repair for rental, and brokerage fees together with, as agreed liquidated damages, the greater of either (i) the amount by which, at the termination of the Lease, the aggregate of the rent (including, without limitation, the tax payments projected on the basis of experience under this Lease) and other sums payable hereunder projected over a period from such termination until the termination date stated herein as the same may have been extended exceeds the aggregate projected fair market rental value of the Leased-Premises for such period, or (ii) an amount equal to the rent (including, without limitation, tax payments projected on the basis of experience under this Lease) and other sums which would have been payable had the Lease not so terminated (subject to off-set for net rents actually received from reletting after subtraction of the expenses of reletting), payable upon the due dates as specified herein. LESSOR may bring legal proceedings for the recovery of such damages, or any installments thereof, from time to time at its election, and nothing contained herein shall be deemed to require LESSOR to postpone suit until the date when the term of this Lease would have expired if it had not been terminated hereunder. Nothing herein contained shall be construed as limiting or precluding LESSOR'S recovery from LESSEE of any amount or damages (including, without limitation, reasonable attorney's fees and expenses) to which, in addition to the damages particularly provided above, LESSOR may lawfully be entitled by reason of any default hereunder on the part of LESSEE. LESSOR and LESSEE agree that, for the purpose of computing liquidated damages, increased tax payments for the period between the termination of this Lease pursuant to this Article and the date of termination called for hereunder as the same may have been extended shall be computed upon the assumption that the amount of the tax payment would increase for each fiscal year during the term by an amount determined by applying the average annual percentage increase over the three (3) Tax Years immediately preceding the Tax Year in which the Lease is terminated. 19.2 LESSOR shall not be in default of any of its obligations unless it shall fail to perform such obligations within thirty (30) days (or such further time as is reasonably necessary) after receipt of written notice thereof from LESSEE. LESSEE shall give like notice to any mortgagee which has so requested in writing, which mortgagee shall have like opportunity to cure. 19.3 If LESSEE shall default in the observance or performance of any term, covenant or condition on its part to be observed or performed under this Lease, LESSOR, without being under any obligation to do so and without thereby waiving such default, may remedy such default for the account and at the expense of LESSEE, immediately and without notice in case of emergency, and in any other case after LESSEE shall fail to remedy such default within the time set forth in this Lease, and after LESSOR shall have given notice to LESSEE of such failure. If LESSOR makes any expenditures or incurs any obligations for the payment of money in connection therewith, including, but not limited to, reasonable attorney's fees and 20

expenses, such sums paid or obligations incurred, with interest at the rate of eighteen percent (18%) shall be paid to LESSOR by LESSEE as rent hereunder. ARTICLE XX - NOTICE Any notice from the LESSOR to the LESSEE relating to the Leased Premises or to the occupancy thereof, shall be deemed duly served, if left at the Leased Premises addressed to the LESSEE or if mailed to the Leased Premises, registered or certified mail, return receipt requested, postage prepaid, or by Federal Express or other overnight mail service, addressed to the LESSEE. Any notice from the LESSEE to the LESSOR relating to the Leased Premises or to the occupancy thereof, shall be deemed duly served, if mailed to the LESSOR by registered or certified mail, return receipt requested, postage prepaid, or by Federal Express or other overnight mail service, addressed to the LESSOR c/o Parsons Commercial Group, 205 Newbury Street, Framingham, Massachusetts 01701, or at such other address as the LESSOR may from time to time advise in writing. ARTICLE XXI - SURRENDER The LESSEE shall at the expiration or other termination of this Lease remove all LESSEE'S goods and effects from the Leased Premises, (including, without hereby limiting the generality of the foregoing, all signs and lettering affixed or painted by the LESSEE, either inside or outside the Leased Premises). LESSEE shall deliver to the LESSOR the Leased Premises and all keys and locks thereto, and other fixtures connected therewith and all alterations and additions made to or upon the Leased Premises, in good condition, ordinary wear and tear, only excepted. In the event of the LESSEE'S failure to remove any of LESSEE'S property from the Leased Premises, LESSOR is hereby authorized, without liability to LESSEE for loss or damage thereto, and at the sole risk of LESSEE, to remove and store any of said property at LESSEE'S expense, or to retain same under LESSOR'S control or to sell at public or private sale, without notice of any or all of the property not so removed and to apply the net proceeds of such sale to the payment of any sum due hereunder, or to destroy such property. ARTICLE XXII - COVENANT OF QUIET ENJOYMENT LESSOR hereby warrants that it and no other person or corporation has the right to Lease the Leased Premises hereby demised. So long as LESSEE shall perform each and every covenant to be performed by LESSEE hereunder (subject to applicable grace periods), LESSEE shall have peaceful and quiet possession of the Leased Premises without hindrance on the part of the LESSOR or persons claiming by or through the LESSOR or anyone under LESSOR'S control. 21

ARTICLE XXIII - NON-WAIVER No reference to any specific right or remedy shall preclude LESSOR from exercising any other right or from having any other remedy or from maintaining any action to which it may otherwise be entitled either at law or in equity. LESSOR'S failure to insist upon a strict performance of any covenant of this Lease or to exercise any option or right herein contained shall not be a waiver or relinquishment for the future of such covenant, right or option, but the same shall remain in full force and effect. ARTICLE XXIV - INTENTIONALLY OMITTED ARTICLE XXV - APPLICABLE LAW This Lease shall be construed under the laws of the Commonwealth of Massachusetts. If any provision of this Lease, or portion thereof, or the application thereof to any person or circumstances shall, to any extent, be invalid or unenforceable, the remainder of this Lease shall not be effected thereby and each provision of this Lease shall be valid and enforceable to the fullest extent permitted by law. ARTICLE XXVI - NO PARTNERSHIP Any intention to create a joint venture or partnership relation between the parties hereto is hereby expressly disclaimed. ARTICLE XXVII - LIABILITY If two or more individuals, corporations, partnerships or other business associations (or any combination of two or more thereof) shall sign this Lease as LESSEE the liability of each individual, corporation, partnership or other business association to pay rent and perform all other obligations hereunder shall be deemed to be joint and several. In a like manner, if the LESSEE named in this Lease shall be a partnership or other business association, the members of which are, by virtue of statute or general law, subject to personal liability, the liability of each such member shall be deemed to be joint and several. LESSEE shall neither assert nor seek to enforce any claim for breach of this Lease against any of LESSOR'S assets other than LESSOR'S interest in the Building and Industrial Park and in the rents, issues and profits thereof, and LESSEE agrees to look solely to such interest for the satisfaction of any liability of LESSOR under this Lease. In no event shall any individual Trustee or beneficiary of the LESSOR (including without limitation all of the officers, trustees, directors, partners, beneficiaries, joint ventures, members' stockholders or other principals or representatives, disclosed or undisclosed, thereof) ever be personally liable for any such liability or ever be liable for damages, whether direct, consequential, punitive or otherwise. Each LESSOR shall be liable only for events occurring during that person's ownership of LESSOR'S estate. 22

ARTICLE XVIII - RULES AND REGULATIONS The rules and regulations attached to this Lease as Exhibit C are made a part of this Lease, and LESSEE agrees to comply with and observe the same. LESSEE'S failure to keep and observe said rules and regulations shall constitute a breach of the terms of this Lease in the manner as if the same were contained herein as covenants. LESSOR reserves the right from time to time to amend or supplement said rules and regulations and to adopt and promulgate additional rules and regulations applicable to the Leased Premises, the Building, and the Industrial Park. Notice of such additional rules and regulations, and amendments and supplements, if any, shall be given to LESSEE and LESSEE agrees thereupon to comply with and observe all such rules and regulations, and amendments thereto and supplements thereof. ARTICLE XXIX - EXAMINATION The submission of this Lease for examination does not constitute a reservation of or option for the Leased Premises, and this Lease becomes effective only upon execution and delivery thereof by LESSOR and LESSEE. ARTICLE XXX - ESTOPPEL LESSEE agrees that at any time and from time to time at reasonable intervals, within ten (10) days after written request by LESSOR, LESSEE will execute, acknowledge and deliver to LESSOR, LESSOR'S mortgagee, or an assignee designated by LESSOR, a writing ratifying this Lease and certifying: (a) that LESSEE has entered into occupancy of the Leased Premises and the date of such entry if such is the case; (b) that this Lease is in full force and effect, and has not been assigned, modified, supplemented or amended in any way (or if there has been any assignments, modification, supplement or amendment, identifying the same) ; (c) that this Lease represents the entire agreement between LESSOR and LESSEE as to the subject matter hereof (or if there has been any assignment, modification, supplement or amendment, identifying the same) ; (d) the date of commencement and expiration of the term; (e) that all conditions under this Lease to be performed by LESSOR have been satisfied and all required contributions by LESSOR to LESSEE on account of LESSEE'S improvements have been received (and, if not, what conditions remain unperformed or contribution unpaid); (f) that to the knowledge of the signer of such writing, except as otherwise stated, no default exists in the performance or observance of any covenant or condition in this Lease and there are no defense or offsets of which the signer may have knowledge; (g) that Minimum Rent and all other rentals have been paid under this Lease, if such be the case. ARTICLE XXXI - SECURITY DEPOSIT LESSEE, contemporaneously with the execution of this Lease, has deposited with LESSOR the sum of Thirteen Thousand Four Hundred Sixteen Dollars Sixty Seven Cents ($13,416.67), receipt of which is hereby acknowledged by LESSOR. In the event that LESSEE commences occupancy of the Premises upon receipt of notice that LESSOR'S work has been completed and otherwise commences performing LESSEE'S obligations as LESSEE 23

under this Lease, then Six Thousand Two Hundred Twenty Nine Dollars Seventeen Cents ($6,229.17) of the deposit shall be applied to the first full month's Minimum Rent due hereunder. The balance of said deposit shall be held by LESSOR, without liability for interest, as security for the faithful performance by LESSEE of all of the terms, covenants, and conditions of this Lease by said LESSEE to be kept and performed during the term hereof. If at any time during the term of this Lease any of the rent herein reserved shall be overdue and unpaid, the LESSOR may, at the option of the LESSOR, upon written notice to LESSEE, appropriate and apply any portion of said deposit to the payment of any such overdue rent or other sum. In the event of the failure of LESSEE to keep and perform any of the terms, covenants and conditions of this Lease to be kept and performed by LESSEE, then the LESSOR at its option, upon written notice to LESSEE, may appropriate and apply said entire deposit or so much thereof as may be necessary, to compensate the LESSOR for loss or damage sustained or suffered by LESSOR due to such breach on the part of LESSEE. Should the entire deposit, or any portion thereof, be appropriated and applied by LESSOR payment of overdue rent for the payment of overdue rent or other sums due and payable to LESSOR by LESSEE hereunder, then LESSEE shall, upon the written demand of LESSOR, forthwith remit to LESSOR a sufficient amount in cash to restore said security to the original sum deposited (less any amount applied to the first month's rent), and LESSEE'S failure to do so within five (5) days after receipt of such demand shall constitute a breach of this Lease. The said deposit, including any additions thereto (or the balance thereof not applied to the first months rent or obligations of LESSEE provided for herein), shall be returned in full to LESSEE at the end of the term of this Lease. ARTICLE XXXII - HOLDOVER If the LESSEE remains in the Leased Premises beyond the expiration of this Lease at the end of the term, or sooner following an early termination as provided for herein, such holding over shall be deemed to create a tenancy-at-will, subject to all of the LESSEE's obligations set forth herein, but at a monthly rate equal to one hundred ten percent (110%) for the first sixty (60) days and one hundred twenty five percent (125%) thereafter of the fixed Minimum Rent and additional rent and other charges provided for under this Lease. The tenancy-at-will may be canceled by either party with a thirty (30) day written notice. ARTICLE XXXIII - NOTICE OF LEASE LESSEE agrees that it will not record this Lease. LESSOR and LESSEE shall, upon request of either, execute and deliver a notice of this Lease in such recordable form as may be required by applicable statute. ARTICLE XXXIV - ALL AMOUNTS ARE RENT All amounts payable by LESSEE to LESSOR under any provision of this Lease shall be deemed to be rent or additional rent for the use of the Leased Premises, and LESSOR'S remedies for the nonpayment of such amounts shall be the same as for nonpayment of Minimum annual Rental. 24

ARTICLE XXXV - ACTS OF GOD In any case where either party is required to do any act other than the payment of rent, delays caused by or resulting from acts of God, war, civil commotion, fire, flood or other casualty, labor difficulties, shortages of labor, materials or equipment, unusual government regulations, unusually severe weather or other causes beyond such party's reasonable control shall not be counted in determining the time during which such act shall be completed, whether such time be designated as a fixed date, a fixed time or "a reasonable time", and such time shall be deemed to be extended by the period of such delay. ARTICLE XXXVI - NO ACCORD AND SATISFACTION No acceptance by LESSOR of a lesser sum than the Minimum Rent, additional rent, or any other charge then due shall be deemed to be other than on account of the earliest installment of such amount due, and notwithstanding any endorsement or statement on any check or any letter accompanying any check for payment, LESSOR may accept such check or payment without prejudice to LESSOR'S right to recover the balance of such amount or pursue any other remedy provided in this Lease or by law. ARTICLE XXXVII - PARTIAL INVALIDITY The invalidity of one more of the provisions of this Lease shall not affect the remaining portions of this Lease; and, if any one or more of the provisions of this Lease should be declared invalid by final order, decree or judgment of a court of competent jurisdiction, this Lease shall be construed as if such invalid provisions had not been included in this Lease. ARTICLE XXXVIII - SIGNAGE LESSOR shall cause LESSEE's name to be lettered on the front of the Building with other lessees of the Building as part of a Building Directory. LESSOR shall also cause LESSEE's name to be posted on the so-called "Park Directory" at the entrance to the Industrial Park. LESSEE shall not install any signage on the exterior of the Leased Premises or visible from outside the Leased Premises, without LESSOR'S prior written approval upon submission of detailed plans. LESSEE may install a free standing sign identifying LESSEE adjacent to the walk in front of the Building, the size and location of which shall be subject to the approval of LESSOR. All of LESSEE'S signage other than the above-mentioned signage for the Building Directory and Industrial Park Directory shall be erected at LESSEE'S sole cost and expense. All such signage must comply in all respects with local legal requirements. LESSOR reserves the right, at any time, to establish sign criteria to which all signs shall be made to conform, at LESSEE'S sole expense. 25

ARTICLE XXXIX - BROKERS LESSEE represents that it has not dealt with any person in connection with the Leased Premises or the negotiation or execution of this Lease other than Cushman & Wakefield of Massachusetts, Inc. and Parsons Commercial Group. LESSOR agrees to pay to Cushman & Wakefield of Massachusetts, Inc. and Parsons Commercial Group all fees and/or commission due in connection with this transaction. LESSEE shall indemnify and save harmless the LESSOR from and against all claims, liabilities, costs and expenses incurred as a result of any breach of the foregoing representation by LESSEE. ARTICLE XL - SUCCESSORS AND ASSIGNS This Lease and the terms hereof shall be binding upon and inure to the benefit of the parties hereto and their permitted successors and assigns. ARTICLE XLI - RIGHT OF FIRST REFUSAL The LESSEE is hereby given the right of first refusal to lease the space adjacent to the Leased Premises designated Suite Number L-2 currently occupied by Conners Design and shown as outlined in blue on Exhibit A (the "Adjacent Premises"). If at any time during the initial term of this Lease (i) while there are at least twenty four (24) months remaining in the initial term, or (ii) after LESSEE has exercised its option to extend hereunder, the Adjacent Premises shall become vacant, LESSEE is not then in default hereunder beyond any applicable grace period, and LESSOR has received an offer to lease all or part of the Adjacent Premises, the LESSOR shall notify the LESSEE of such fact, and the LESSEE shall thereupon have the right within ten (10) days from the receipt of notice from LESSOR to elect to lease such Adjacent Premises. LESSEE may exercise such right only by providing written notice of its election to exercise such right to LESSOR within ten (10) days of receipt of LESSOR'S notice. If the LESSEE shall not so elect within the said period, the LESSOR may then lease said Adjacent Premises or any portion thereof to any potential lessee upon such terms, conditions, and rental as LESSOR, in its sole discretion, determines. If the LESSEE elects to exercise said right of first refusal, the Adjacent Premises shall be delivered in "AS IS" condition on the later of ten (10) days after receipt of LESSEE's notice and the date that the same became vacant. If the LESSEE elects to exercise such right of first refusal, the parties shall enter into an amendment to this Lease providing that the rent per square foot and terms and conditions of lease of the Adjacent Premises shall be the same as contained in this Lease and that this Lease shall be amended to include the Adjacent Premises, and to the extent that LESSEE'S option to extend has or may be exercised with respect to the Premises, it shall also be deemed to have been exercised with respect to the Adjacent Premises. The right of first refusal herein contained shall expire on the first to occur of the following (i) the failure of the LESSOR and LESSEE to execute an amendment to this Lease for any reason whatsoever within ten (10) days after the election by LESSEE to exercise its right of first refusal, or (ii) LESSEE'S failure to notify LESSOR of its exercise of its right to lease the Adjacent Premises after notice duly given by LESSOR. 26

ARTICLE XLII - OPTION TO EXPAND PREMISES The LESSEE is hereby given the right during the term to lease the approximately Five Thousand (5,000) square feet in the Building, contiguous to the Premises and outlined in green on Exhibit A (the "Expansion Premises"). At any time during the initial term of this Lease while there are at least twelve (12) months remaining in the initial term, and provided LESSEE is not then in default hereunder, the LESSEE shall have the right to elect to lease such Expansion Premises by providing LESSOR with at least ninety (90) days advance written notice of its election to lease the Expansion Premises beginning no later than twelve (12) months prior to the expiration of the initial term. If the LESSEE elects to exercise said option, the Expansion Premises shall be delivered in "AS IS" condition and this Lease shall be amended to include the Expansion Premises. Such amendment shall provide, inter alia, (i) for Minimum Rent at the annual rate of Four Dollars ($4.00) per square foot during the initial term and at Ninety Five Percent (95%) of fair market value as determined in accordance with Article 4.2 hereof during the extension term, and (ii) that any buildout agreed to between LESSOR and LESSEE which is accomplished by LESSOR shall be amortized over the then remaining term of the Lease. ARTICLE XLIII - FINANCING REQUIREMENTS If in connection with obtaining financing for the Office Building, a bank, insurance company, pension trust or other institutional lender shall request reasonable modifications in this Lease as a condition to such financing, LESSEE will not unreasonably withhold, delay, or condition its consent thereto, provided that such modifications do not increase the obligations of LESSEE hereunder or materially adversely affect the leasehold interest hereby created. ARTICLE XLIV - CAPTIONS AND HEADINGS The captions and headings used herein are intended only for the convenience of the reference and are not to be used in construing this instrument. ARTICLE XLV - ENTIRE AGREEMENT This Lease and the Exhibits hereto constitute the full and complete agreement between the parties hereto and are no other terms, obligations, covenants, representations, warranties or conditions other than contained herein. 27

SEVEN OCTOBER HILLS LLC. EXHIBIT C RULES AND REGULATIONS 1. In the event of any conflict between the terms of these rules and regulations and the express provisions of the Lease, the express, applicable provisions of the Lease shall control. LESSOR reserves the right, without the approval of LESSEE, to rescind, add to and amend any rules or regulations, to add new reasonable rules or regulations and to waive any rules or regulations with respect to any lessee or lessees. LESSEE shall provide a copy of these rules and regulations to each of its employees to facilitate compliance with these standards. 2. The sidewalks, plaza entries, corridors and staircases of the Building shall not be obstructed, and shall not be used by LESSEE, or the employees, agents, servants, visitors or invitees of LESSEE, for any purpose other than ingress and egress to and from the Premises. No skateboards, roller skates, roller blades or similar items shall be used in or about the Building. 3.
