BECAUSE IT IS A SUMMARY, IT DOES NOT CONTAIN ALL OF THE INFORMATION THAT YOU SHOULD CONSIDER BEFORE INVESTING IN THE SHARES. YOU SHOULD READ THE ENTIRE PROSPECTUS AND THE DOCUMANTS INCORPORATED HEREIN BY REFERENCE CAREFULLY. OUR COMPANY OVERVIEW We are a leader in the commercialization of genomics-based drug discovery. We have over ten years of experience in genomic research and have been selected as the only commercial genomics company to participate in the Human Genome Project sponsored by the United States government. Our commercial strategy is to apply our broad understanding of human and infectious disease genomics and our integrated proprietary technologies to identify and validate novel drug targets for commercialization through alliances with pharmaceutical companies. We currently have six alliances to develop drugs to treat or diagnose a variety of human and infectious diseases. Our multi-year alliances with Wyeth-Ayerst, Schering-Plough, AstraZeneca, and bioMerieux combine our genomics expertise with our partners' small molecule drug libraries and world-class commercialization franchises. We are working with our partners to develop drugs for major indications such as osteoporosis, asthma, ulcers, drug resistant bacterial infections and fungal infections as well as genomic-based diagnostics for infectious diseases. Our depth of experience in the genomics field has permitted us to emerge as a leader in creating industrial scale genomics tools for product development. Our tools include: - high-throughput sequencing - sequence finishing - bioinformatics - functional genomics - assay development Our fully-integrated genomics technologies, highly automated processes and information systems are designed to rapidly generate comprehensive information about gene sequences, gene expression, and biological pathways that we use to identify and validate targets for the development of new therapeutic and diagnostic products. We are concentrating our product discovery efforts in two principal areas: human diseases believed to have a significant genetic component and infectious diseases caused by pathogens, including bacteria and fungi. We are pursuing the discovery of products based on our genomic discoveries both through strategic alliances with corporate partners and through internal research programs. In the area of human diseases, we have alliances with Wyeth-Ayerst Laboratories, the pharmaceutical division of American Home Products Corporation, to develop treatments for osteoporosis and with Schering-Plough Corporation to develop treatments for asthma. In the area of infectious diseases, we have ongoing alliances with Schering-Plough to develop treatments for drug resistant bacterial infections, including STAPH. AUREUS, and to develop novel antifungals. We are working with AstraZeneca PLC to develop treatments for ulcers caused by H. PYLORI and have partnered with bioMerieux Incorporated to develop diagnostics for infectious diseases. As part of our emerging businesses, we are continuing to invest in our internal infectious disease franchise and build our pharmacogenomics program. We are typically entitled to receive a combination of up-front license fees, 1 research funding, milestone payments, and royalty payments on product sales in exchange for a license to our genetic research data and other information in our alliances. We have extensive experience in high-throughput sequencing. In addition to the sponsored genomic sequencing research done on behalf of the U.S. government, we also provide customized sequencing services to biotechnology companies and pharmaceutical companies that need industrial scale, high quality customized sequencing capability but may lack the expertise or in-house capacity to carry out the project. Since the launch of our GTC Sequencing Center in July 1999, we have entered into sequencing contracts with thirteen commercial, government and research customers. In 1997, we introduced our PathoGenome Database, a database consisting of genetic information from over thirty microbial organisms, a substantial part of which is proprietary to us. We have granted to six companies non-exclusive access to a large volume of highly organized and functionally annotated sequence information related to some of the most medically important microbial organisms and fungi. We are continuing to explore ways to leverage this genomic asset by pursuing alliances that will facilitate broader access to our PathoGenome Database. We are also internally funding programs to create additional value from our existing competitive strengths in genomics. We are seeking to develop new, more effective drugs through both our pharmacogenomics and infectious disease programs. We plan to work with collaborators to identify more appropriate patient populations using pharmacogenomics to enable the development of more effective, safer drugs and "rescue" promising drugs that could succeed in trials using pre-selected populations based upon genetically determined responsiveness. We are also mining our PathoGenome Database to identify genes that are novel targets for our internally funded infectious disease program. Our proprietary technology has enabled our scientists to discover genes that are essential for the survival of pathogenic organisms and to identify broad spectrum microbial targets that are essential in bacteria. 2 RISK FACTORS THIS OFFERING INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD CONSIDER CAREFULLY THE RISKS DESCRIBED BELOW BEFORE YOU DECIDE TO BUY OUR COMMON STOCK. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES FACING US. ADDITIONAL RISKS NOT PRESENTLY KNOWN TO US OR THAT WE CURRENTLY DEEM IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS OPERATIONS. IF ANY OF THE FOLLOWING RISKS WERE TO OCCUR, OUR BUSINESS, FINANCIAL CONDITION OR RESULTS OF OPERATIONS WOULD LIKELY SUFFER. IN THAT EVENT, THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE, AND YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT. RISKS RELATED TO OUR BUSINESS WE HAVE A HISTORY OF SIGNIFICANT OPERATING LOSSES AND EXPECT THESE LOSSES TO CONTINUE IN THE FUTURE. We have experienced significant operating losses since our inception and expect these losses to continue for the foreseeable future. We had a net loss of approximately $6,328,000 for the fiscal year ended August 31, 1999 and a net loss of approximately $195,000 for the twenty-six-week period ended February 26, 2000, and, as of February 26, 2000, we had an accumulated deficit of approximately $66,892,000. The losses have resulted primarily from costs incurred in research and development and from general and administrative costs associated with our operations. These costs have exceeded our revenues which to date have been generated principally from collaborations and government grants. We anticipate incurring additional losses this year and in future years and cannot predict when, if ever, we will achieve profitability. These losses may increase in the near future as we expand our research and development activities. In addition, our partners' product development efforts which utilize our products are at an early stage and, accordingly, we do not expect our losses to be substantially mitigated by revenues from milestone payments or royalties under those agreements for a number of years, if ever. USE OF GENOMIC INFORMATION TO DEVELOP OR COMMERCIALIZE PRODUCTS IS UNPROVEN. The development of new drugs and the diagnosis of disease based on genomic information is unproven. Our business strategy is based on the assumption that identifying and characterizing genes and sequencing select human genes and the genomes of select pathogens may help scientists better understand complex disease processes and develop drugs to treat these diseases. There is limited understanding of the roles of genes in diseases. Few therapeutic, vaccine or diagnostic products based on genomic information have been developed and commercialized. To date, no one has developed or commercialized any pharmaceutical, diagnostic or vaccine products based on our technologies. If we fail to identify genes useful for the discovery and development of such products, or if partners are unable to use the genomic information that we provide to them to develop such products, our current and potential customers may lose confidence in our products or their value for drug discovery, and our business may suffer as a result. WE RELY HEAVILY UPON EXISTING AND PROSPECTIVE ALLIANCE PARTNERS AND LICENSEES, AND A SIGNIFICANT PORTION OF OUR REVENUE HAS BEEN DERIVED FROM ONE ALLIANCE PARTNER. Our strategy for developing and commercializing therapeutic, vaccine and diagnostic products depends, in large part, on strategic alliances and licensing arrangements with pharmaceutical and biotechnology partners. We currently have alliances with AstraZeneca, bioMerieux, Schering-Plough, and Wyeth-Ayerst. We have received a substantial portion of our revenue from these alliances, and we expect to continue to do so. Under these arrangements we are entitled to receive payments and royalties based on the achievement by us and our partners of certain development milestones and the successful development of products arising from the collaborations. Although we have achieved many of the scientific milestones under our agreements, we cannot assure you that we will continue these 3 achievements in the future or that milestones dependent on our partners' development and commercialization activities will be attained. In addition, we cannot assure you that we will maintain our current collaborations or establish additional collaborations. Competition among genomics companies for collaborations with pharmaceutical companies is intense. This competition is enhanced by the trend towards consolidation among large pharmaceutical companies. Consequently, we cannot be sure that we will be able to enter into new collaborations or maintain our existing ones, and any new or renewed collaborations may be on terms less favorable to us than past collaborations. Our failure to maintain existing collaborations or to enter into additional collaborations would have a material adverse effect on our business. In particular, if funding from partners was not available or was reduced, we would need to devote additional internal resources to our research programs or possibly scale back or terminate some programs. Since 1996, we have received a significant amount of revenues based on payments under our alliances with Schering-Plough. We have two infectious disease alliances with Schering-Plough and a third alliance with Schering-Plough that relates to asthma genetics. The funded research phase under these agreements is scheduled to end in March 2000, September 2001 and December 2001, respectively. In addition, Schering-Plough is a subscriber to our PathoGenome Database. For the fiscal years ended August 31, 1997, 1998 and 1999 and the twenty-six week period ended February 26, 2000, revenues from Schering-Plough accounted for approximately 48%, 71%, 75% and 55%, respectively, of our total revenue. If Schering-Plough fails to extend the funded research phase of the agreements scheduled to end in September 2001 or December 2001, we would lose significant research funding, which could have a material adverse effect on us. Our strategy includes entering into multiple, concurrent alliances. We cannot assure you that we will be able to continue to manage multiple alliances successfully. The risks we face in managing multiple alliances include maintaining confidentiality among partners, avoiding conflicts between partners and avoiding conflicts between us and our partners. If we fail to manage our alliances effectively, or if any of the problems described above arise, one or more of the following could occur which could have a material adverse effect on our business: - use of significant resources to resolve conflicts - delay in research - legal claims involving significant time - expense - loss of reputation - termination of one or more alliances - loss of capital and loss of revenues If our partners develop products using our genomic information, we will rely on these partners for product development, regulatory approval, manufacturing and marketing of those products before we can receive some of the milestone payments, royalties and other payments to which we may be entitled under the terms of some of our collaboration agreements. Our agreements with our partners typically allow the partners significant discretion in electing whether to pursue any of these activities. We cannot control the amount and timing of resources our partners may devote to our programs or potential products. As a result, we cannot assure you that our partners will perform their obligations as expected. In addition, if a partner is involved in a business combination, such as a merger or acquisition, or changes its business focus, its performance in our agreement may suffer and, as a result, we may not 4 generate any revenues from the royalty, milestone and similar payment provisions of our alliance agreement with that partner. OUR ALLIANCE PARTNERS MAY NOT BE SUCCESSFUL IN DEVELOPING OR COMMERCIALIZING THERAPEUTIC, DIAGNOSTIC OR VACCINE PRODUCTS UNDER OUR AGREEMENTS WITH THEM. Development of therapeutic, diagnostic and vaccine products based on our discoveries will be subject to the high risks of failure inherent in the development or commercialization of health care products. These risks include the possibility that any such products will be found to be toxic, be found to be ineffective, fail to receive and maintain necessary regulatory approvals, be difficult or impossible to manufacture on a large scale, be uneconomical to market, fail to be developed prior to the successful marketing of similar products by competitors or infringe on proprietary rights of third parties. OUR CURRENT AND POTENTIAL ALLIANCE PARTNERS ARE PRIMARILY FROM, AND ARE SUBJECT TO RISKS FACED BY, THE PHARMACEUTICAL AND BIOTECHNOLOGY INDUSTRIES. We derive a substantial portion of our revenues from fees paid by pharmaceutical companies for our information products and services. We expect that pharmaceutical and biotechnology companies will be our primary source of revenues for the foreseeable future. As a result, we are subject to risks and uncertainties that affect the pharmaceutical and biotechnology industries and to reduction and delays in research and development expenditures by companies in these industries. These effects on the pharmaceutical and biotechnology industries may affect our ability to conclude deals with collaborative partners. In addition, our future revenues may be adversely affected by mergers and consolidation in the pharmaceutical and biotechnology industries, which will reduce the number of our potential customers. Large pharmaceutical and biotechnology customers could also decide to conduct their own genomic programs, rely on publicly available information or join consortia or seek other providers instead of using our products and services. THE GENOMICS INDUSTRY IS INTENSELY COMPETITIVE AND EVOLVING. There is intense competition among entities attempting to sequence segments of the human genome and identify genes associated with specific diseases and develop products and services based on these discoveries. We face competition in these areas from genomic, pharmaceutical, biotechnology and diagnostic companies, academic and research institutions and government or other publicly-funded agencies, both in the United States and abroad. One of our competitors has announced that it expects to complete the sequencing of the entire human genome before the end of 2000, which could adversely affect our business. Some of our competitors are developing databases containing gene sequence, gene expression, genetic variation or other genomic information and are marketing or plan to market their data to pharmaceutical companies. Additional competitors may attempt to establish databases containing this information in the future. In addition, some entities are attempting to identify and patent randomly sequenced genes and gene fragments, while others are pursuing a gene identification, characterization and product development strategy based on other genomic technologies. Numerous pharmaceutical companies also are developing genomic research programs, either alone or in partnership with our competitors. Competition among these entities to sequence genes, identify and characterize genes of interest, obtain patent protection and market this genomic information is intense and is expected to increase. In order to compete against existing and future technologies, we will need to demonstrate to potential customers that our technologies and capabilities are superior to those of our competitors. 5 Many of our competitors have substantially greater capital resources, sequencing capabilities, research and developmental staffs, facilities, manufacturing and marketing experience, distribution channels and human resources than us. These competitors may discover, characterize or develop important genes, drug targets or leads, drug discovery technologies or drugs before us or our customers or which are more effective than those developed by us or our customers, or may obtain regulatory approvals of their drugs more rapidly than our customers do, any of which could have a material adverse effect on any of our similar programs. Moreover, these competitors may obtain patent protection or other intellectual property rights that would limit our rights or our customers' ability to use our products to commercialize therapeutic, diagnostic or vaccine products. In addition, in our internal development efforts we may compete with our customers to whom we have granted access to our proprietary databases. Future competition will come from existing competitors as well as other companies seeking to develop new technologies for drug discovery based on gene sequencing, target gene identification, bioinformatics and related technologies. In addition, certain pharmaceutical and biotechnology companies have significant needs for genomic information and may choose to develop or acquire competing technologies to meet such needs. In the area of bioinformatics, we also face competition from providers of software. A number of companies have announced their intent to develop and market software to assist pharmaceutical companies and academic researchers in managing and analyzing their own genomic data and publicly available data. WE FACE RAPID TECHNOLOGICAL CHANGE IN THE GENOMICS INDUSTRY WHICH COULD RESULT IN DRUG DEVELOPMENT TECHNOLOGY SUPERIOR TO THAT WHICH WE ARE DEVELOPING. The field of genomics is characterized by significant and rapid technological change. Many of our competitors have greater research and development capabilities and experience, as well as greater financial resources than do we. They may develop techniques for genomic-based drug discovery that are superior to those we are developing and render our technologies non-competitive or obsolete even before they generate revenue. WE PLAN TO MAKE A SUBSTANTIAL INVESTMENT TO BUILD A NEW PHARMACOGENOMICS PROGRAM AND INCREASE OUR INVESTMENT IN OUR INFECTIOUS DISEASE FRANCHISE, BOTH OF WHICH ARE COMMERCIALLY UNPROVEN, AND ARE AREAS IN WHICH WE LACK EXTENSIVE OPERATING EXPERIENCE. The area of pharmacogenomics is relatively new and it has not been proven to be commercially viable. We intend to make a significant investment to build a new pharmacogenomics program. We lack extensive experience in utilizing pharmacogenomics in drug development programs or in marketing our pharmacogenomics capabilities to pharmaceutical companies. In the area of infectious disease, we plan to move further down the drug development process toward identifying and validating compounds internally. This activity will require increased research and development investment in an area where we lack experience. If our new product programs in either of these areas prove unsuccessful, our results of operations may be materially adversely affected. OUR INTELLECTUAL PROPERTY PROTECTION MAY BE INADEQUATE TO PROTECT OUR PROPRIETARY RIGHTS. Our success will depend, in part, on our ability to obtain commercially valuable patent claims and protect our intellectual property. Our patent position is generally uncertain and involves complex legal and factual questions. Legal standards relating to the validity and scope of claims in our technology field are still evolving. Therefore, the degree of future protection for our proprietary rights is uncertain. 6 The risks and uncertainties that we face with respect to our patents and other proprietary rights include the following: - the pending patent applications we have filed or to which we have exclusive rights may not result in issued patents or may take longer than we expect to result in issued patents - the claims of any patents which are issued may be limited from those in our patent applications as filed and may not provide meaningful protection - we may not be able to develop additional proprietary technologies that are patentable - the patents licensed or issued to us or our customers may not provide a competitive advantage - other companies may challenge patents licensed or issued to us or our customers - patents issued to other companies may substantially impair our ability to conduct our business - other companies may independently develop similar or alternative technologies or duplicate our technologies - other companies may design around technologies we have licensed or developed We may apply for patent protection for compositions and methods relating to gene expression and disease-specific patterns of gene expression that we identify and individual disease genes and targets that we discover. These patent applications may include claims relating to novel genes, gene fragments or encoded protein and to novel uses for known genes, gene fragments or proteins identified from the use of our genomic information and our databases. We may not be able to obtain meaningful patent protection for our discoveries. Even if patents are issued, their scope of coverage or protection is uncertain. For example, we or our collaborators have filed patent applications with respect to a number of full length genes and corresponding proteins and partial genes of H. PYLORI, of M. LEPRAE and several other organisms. These applications seek to protect these full length and partial gene sequences and corresponding proteins, as well as equivalent sequences and products and uses derived from these sequences and proteins. Some court decisions indicate that disclosure of a partial sequence may not be sufficient to support the patentability of a full length sequence. In addition, we are aware that companies have published patent applications relating to nucleic acids encoding several H. PYLORI proteins and, in other disease programs, relating to genes for which we have found mutations of interest. If these companies are issued patents, their patents may limit our ability and the ability of our collaborators to practice under any patents that may be issued to us or our collaborators. Because of this, we or our collaborators may not be able to obtain patents with respect to the genes of infectious agents such as H. PYLORI, or the value of certain other patents issued to us or our collaborators that are the subject of other collaborations may be limited. Also, even if a patent were issued to us, the scope of coverage or protection afforded to such patent may be limited. OUR PROPRIETARY POSITION MAY DEPEND ON OUR ABILITY TO PROTECT TRADE SECRETS. We rely on trade secret protection for our confidential and proprietary information and procedures, including procedures related to sequencing genes and to searching and identifying important regions of genetic information. We currently protect such information and procedures as trade secrets. We protect our trade secrets through recognized practices, including access control, confidentiality agreements with employees, consultants, collaborators, and customers, and other security measures. These confidentiality agreements may be breached, however, and we may not have adequate remedies for any such breach. In addition, our trade secrets may otherwise become known or be independently developed by competitors. 7 WE MAY INFRINGE THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES AND MAY BECOME INVOLVED IN EXPENSIVE INTELLECTUAL PROPERTY LITIGATION. The intellectual property rights of biotechnology companies, including our company, are generally uncertain and involve complex legal, scientific and factual questions. Our success in the functional genomics field may depend, in part, on our ability to operate without infringing on the intellectual property rights of others and to prevent others from infringing on our intellectual property rights. There has been substantial litigation regarding patents and other intellectual property rights in the genomics industry. We may become party to patent litigation or proceedings at the U.S. Patent and Trademark Office or a foreign patent office to determine our patent rights with respect to third parties which may include subscribers to our database information services. Interference proceedings in the U.S. Patent Office or opposition proceedings in a foreign patent office may be necessary to establish which party was the first to discover such intellectual property. We may become involved in patent litigation against third parties to enforce our patent rights, to invalidate patents held by such third parties, or to defend against such claims. The cost to us of any patent litigation or similar proceeding could be substantial, and it may absorb significant management time. If an infringement litigation against us is resolved unfavorably to us, we may be enjoined from manufacturing or selling certain of our products or services without a license from a third party. We may not be able to obtain such a license on commercially acceptable terms, or at all. The U.S. Patent and Trademark Office has begun issuing patents to third parties relating to single nucleotide polymorphisms, commonly referred to as SNPs. We believe that many patent applications covering SNPs have been filed with the U.S. PTO. Therefore, our ability to obtain patent protection on SNPs could be reduced. PUBLIC DISCLOSURE OF GENOMICS SEQUENCE DATA COULD JEOPARDIZE OUR INTELLECTUAL PROPERTY PROTECTION AND HAVE AN ADVERSE EFFECT ON THE VALUE OF OUR PRODUCTS AND SERVICES. The federally funded Human Genome Project and other research consortia engaged in similar research have committed to make available to the public basic human sequence data. These disclosures might limit the scope of our claims or make subsequent discoveries related to full-length genes unpatentable. We cannot be certain that such publication of sequence data has not affected and will not affect the ability to obtain patent protection. Customers may conclude that uncertainties about this type of protection decrease the value of our information products and services, and as a result, we may be required to reduce the fees we charge for these products and services. In addition, there has been recent public discussion questioning whether patent protection should be available for gene sequences. If we or our partners are unable to obtain patents for gene sequences, our business could be materially adversely affected. WE MAY NOT BE ABLE TO OBTAIN MEANINGFUL PATENT PROTECTION FOR DISCOVERIES UNDER OUR GOVERNMENT CONTRACTS. Under our government grants and contracts, the government has a statutory right to practice or have practiced any inventions developed under the government research contracts. In addition, under certain circumstances, such as inaction on our part or the part of our licensees to achieve practical application of the invention or a need to alleviate public health or safety concerns not reasonably satisfied by us or our licensees, the government has the right to grant to other parties licenses to any inventions first reduced to practice under the government grants and contracts. If the government grants such a license to a third party, our patent position may be jeopardized. In addition, the government has ownership rights in the data, clones, genes and other material derived from the material furnished to us by the government, while we have ownership rights in other technology developed solely by us. We are also obligated under certain government grants to submit sequencing 8 data and materials resulting from our research to public databases within 24 hours from the date such data and materials are developed. Our ability to obtain patent protection for our discoveries and inventions may be adversely affected by this publication. INTERNATIONAL PATENT PROTECTION IS UNCERTAIN. Patent law outside the United States is uncertain and is currently undergoing review and revision in many countries. Further, the laws of some foreign countries may not protect our intellectual property rights to the same extent as U.S. laws. We may participate in opposition proceedings to determine the validity of our or our competitors' foreign patents, which could result in substantial costs and diversion of our efforts. Finally, some forms of patent protection available in the United States are not available to us in foreign countries due to the laws of those countries. THE USE OF OUR GENOMIC PRODUCTS AND SERVICES BY OUR CUSTOMERS MAY BE SUBJECT TO GOVERNMENT REGULATION. The manufacture and marketing of products which may be developed by us or our collaborators are subject to certain U.S. Food and Drug Administration or other regulatory approvals. For example, any new drug developed by our efforts or the efforts of our customers must undergo an extensive regulatory review process. This process can take many years and require substantial expense. Also, changes in FDA policies and the policies of similar foreign regulatory bodies can increase the delay for each new drug, product license and biological license application. We expect similar delays in the regulatory review process for any diagnostic or agricultural product, where similar review or other approval is required. Even if marketing clearance is obtained, a marketed product and its manufacturer are subject to continuing review. Discovery of previously unknown problems with a product may result in withdrawal of the product from the market. Furthermore, we may be directly subject to regulations as a provider of diagnostic information. To the extent that such regulations restrict the sale of our products or impose other costs, our business may be materially adversely affected. OUR RESEARCH AND PRODUCT DEVELOPMENT DEPENDS ON ACCESS TO TISSUE SAMPLES AND OTHER BIOLOGICAL MATERIALS AND GENE DATA FROM INDIVIDUALS. To continue to build our database products, we will need access to normal and diseased human and other tissue samples, other biological materials and related clinical and other information, which may be in limited supply. We compete with many other companies for these materials and information. We may not be able to obtain or maintain access to these materials and information on acceptable terms. In addition, government regulation in the United States and foreign countries could result in restricted access to, or use of, human and other tissue samples. If we lose access to sufficient numbers or sources of tissue samples, or if tighter restrictions are imposed on our use of the information generated from tissue samples, our business may be harmed. Competition among genomics companies is also increasing for access to unique data from related individuals that we use to identify genes for specific human diseases. ETHICAL, LEGAL AND SOCIAL ISSUES RELATED TO THE USE OF GENETIC INFORMATION AND GENETIC TESTING MAY CAUSE LESS DEMAND FOR OUR PRODUCTS. Genetic testing has raised issues regarding confidentiality and the appropriate uses of the resulting information. For example, concerns have been expressed towards insurance carriers and employers using such tests to discriminate on the basis of such information, resulting in barriers to the acceptance of such tests by consumers. This could lead to governmental authorities calling for limits on or regulation of the use of genetic testing or prohibit testing for genetic predisposition to certain diseases, 9 particularly those that have no known cure. Any of these scenarios could reduce the potential markets for our products. WE RELY ON FUNDING FROM THE UNITED STATES GOVERNMENT. As of February 26, 2000, we had approximately $25.1 million of government research contracts outstanding under which we had not yet completed all of the services. Funding under our government grants and research contracts is subject to appropriation each year by the United States Congress and can be discontinued or reduced at any time. In addition, we cannot be certain that we will receive additional grants or contracts in the future. The government's failure to fund our research in this area not only would end our participation in the program, but might adversely affect the industry-wide perception of genomics and the utility of genomic information. WE MAY NOT SUCCEED IN REALIZING ANY ADDITIONAL REVENUE FROM THE PATHOGENOME DATABASE. In 1997, we introduced the PathoGenome Database which consists of genetic information from more than thirty microbial organisms. Our strategy for our database depends on entering into subscription agreements with pharmaceutical, biotechnology and other companies for the use of our database. Each of the agreements that we have with our customers is for a specific term, and we expect that they may not be renewed upon expiration. If any agreements expire and are not renewed and we are unsuccessful in broadening access to our database, our business could suffer. OUR SALES CYCLE IS LENGTHY AND WE MAY SPEND CONSIDERABLE RESOURCES ON UNSUCCESSFUL NEGOTIATION EFFORTS OR MAY NOT BE ABLE TO COMPLETE DEALS ON THE SCHEDULE ANTICIPATED. Our ability to obtain new customers for genomic information products depends on our customers' belief that we can help accelerate their drug discovery efforts. Our negotiation cycle is typically lengthy because we need to educate potential customers and sell the benefits of our products and services to a variety of constituencies within companies. In addition, each agreement involves the negotiation of unique terms. We may expend substantial funds and management effort with no assurance that an agreement will result. Actual and proposed consolidations of pharmaceutical companies have affected and may in the future affect the timing and progress of our ability to conclude deals with collaborative partners. WE MAY NEED TO RAISE ADDITIONAL FUNDS IN THE FUTURE. We believe that the net proceeds of this offering together with existing cash and marketable securities, borrowings under equipment financing arrangements and anticipated cash flow from operations will be sufficient to support our current plans for at least one year. However, we may choose to raise additional capital due to market conditions or strategic considerations even if we have sufficient funds for our operating plan. In particular, we may need additional funds to increase our research and development activities. We may seek funding through additional public or private equity offerings, debt financings or agreements with customers. If we raise additional capital by issuing equity or convertible debt securities, the issuances may dilute share ownership of existing investors and future investors may be granted rights superior to those of current shareholders. Additional financing may not be available when needed, or, if available, may not be available on favorable terms. If we cannot obtain adequate financing on acceptable terms when such financing is required, our business will be adversely affected. WE DEPEND ON KEY PERSONNEL IN A HIGHLY COMPETITIVE MARKET FOR SKILLED PERSONNEL. We are highly dependent on the principal members of our senior management and key scientific and technical personnel. None of our employees are bound by a long term employment agreement, a 10 non-competition agreement or are the subject of key man life insurance, other than Robert J. Hennessey who has a non-competition agreement. The loss of any of these personnel could have a material adverse effect on our ability to achieve our goals. Our future success is also dependent upon our ability to attract and retain additional qualified scientific, technical and managerial personnel. Our plan to build our pharmacogenomics program will require us to hire a number of new personnel with expertise in this area. We experience intense competition for qualified personnel and may not be able to continue to attract and retain skilled personnel necessary for the development of our business. OUR ACTIVITIES INVOLVE HAZARDOUS MATERIALS AND MAY SUBJECT US TO ENVIRONMENTAL LIABILITY. Our research and development involve the controlled use of hazardous and radioactive materials and biological waste. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these materials and certain waste products. Although we believe that our safety procedures for handling and disposing of these materials comply with legally prescribed standards, we cannot completely eliminate the risk of accidental contamination or injury from these materials. In the event of an accident, we could be held liable for damages or penalized with fines, and this liability could exceed our resources. We believe that we are in compliance in all material respects with applicable environmental laws and regulations and currently do not expect to make material additional capital expenditures for environmental control facilities in the near term. However, we may have to incur significant costs to comply with current or future environmental laws and regulations. WE MAY HAVE DIFFICULTY MANAGING OUR GROWTH. We expect to continue to experience growth in the number of our employees and customers and the scope of our operations. In particular, we plan significant growth in our sequencing and pharmacogenomics business. This growth may continue to place a significant strain on our management and operations. Our ability to manage this growth will depend upon our ability to broaden our management team and our ability to attract, hire and retain skilled employees. Our success will also depend on the ability of our officers and key employees to continue to implement and improve our operational and other systems, to manage multiple, concurrent customer relationships and to hire, train and manage our employees. In addition, we must continue to invest in customer support resources as the number of database customers and their requests for support increase. Our customers may have worldwide operations and require support at multiple U.S. and foreign sites. RISKS RELATED TO THE SECURITIES MARKET AND THIS OFFERING OUR STOCK PRICE IS HIGHLY VOLATILE. The market price of our stock has been and is likely to continue to be highly volatile due to the risks and uncertainties described in this section of the prospectus, as well as other factors, including: - conditions and publicity regarding the genomics or life sciences industries generally - termination of, or an adverse development in, our strategic alliances, subscription agreements, or commercial or governmental contract sequencing arrangements - price and volume fluctuations in the stock market at large which do not relate to our operating performance - comments by securities analysts, or our failure to meet market expectations - the level of investment in our new pharmacogenomics program 11 - the timing of achievement of our development milestones and other payments under our strategic alliance agreements The stock market has from time to time experienced extreme price and volume fluctuations that are unrelated to the operating performance of particular companies. In the past, companies that have experienced volatility have sometimes been the subject of securities class action litigation. If litigation were instituted on this basis, it could result in substantial costs and a diversion of management's attention and resources. MULTIPLE FACTORS BEYOND OUR CONTROL MAY CAUSE FLUCTUATIONS IN OUR OPERATING RESULTS AND MAY CAUSE OUR BUSINESS TO SUFFER. Our revenues and results of operations may fluctuate significantly, depending on a variety of factors, including the following: - our success in concluding deals for, and changes in the demand for, our products - variations in the timing of payments from partners and customers and the recognition of these payments as revenues - the terms we are able to negotiate in our deals - the timing of our new product introductions, if any - changes in the research and development budgets of our customers and potential customers - the introduction of new products and services by our competitors - regulatory actions - expenses related to, and the results of, litigation and other proceedings relating to intellectual property rights - the cost and timing of our adoption of new technologies - the cost, quality and availability of cell and tissue samples, reagents and related components and technologies, including those supplied to us pursuant to contractual arrangements - our sales cycle for concluding alliances and other deals is lengthy We will not be able to control many of these factors. In addition, if our revenues in a particular period do not meet expectations, we may not be able to adjust our expenditures in that period, which could cause our business to suffer. We believe that period-to-period comparisons of our financial results will not necessarily be meaningful. You should not rely on these comparisons as an indication of our future performance. If our operating results in any future period fall below the expectations of securities analysts and investors, our stock price may fall, possibly by a significant amount. FUTURE ACQUISITIONS MAY ABSORB SIGNIFICANT RESOURCES AND MAY BE UNSUCCESSFUL. As part of our strategy, we may pursue acquisitions, investments and other relationships and alliances. Acquisitions may involve significant cash expenditures, debt incurrence, additional operating losses, dilutive issuances of equity securities, and expenses that could have a material adverse effect on our financial condition and results of operations. For example, to the extent that we elect to pay the purchase price for such acquisitions in shares of our stock, the issuance of additional shares of our stock will be dilutive to our stockholders. Acquisitions involve numerous other risks, including: - difficulties integrating acquired technologies and personnel into our business - diversion of management from daily operations 12 - inability to obtain required financing on favorable terms - entering new markets in which we have little or no previous experience - potential loss of key employees or customers of acquired companies - assumption of the liabilities and exposure to unforseen liabilities of acquired companies - amortization of the intangible assets of acquired companies It may be difficult for us to complete these types of transactions quickly and to integrate the businesses efficiently into our current business. Any acquisitions or investments by us may ultimately have a negative impact on our business and financial condition. FOLLOWING THE OFFERING, OUR SHAREHOLDERS MAY BE ABLE TO SELL SHARES WHICH COULD ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK. Upon completion of this offering and assuming we sell all of the shares offered, we will have approximately 24,038,566 shares of common stock outstanding, assuming no exercise of outstanding options to purchase common stock and excluding the restricted shares of common stock granted but not yet issued. Substantially all outstanding shares of our common stock are eligible for an immediate resale as a result of having been registered for resale under the Securities Act, pursuant to the provisions of Rule 144 or otherwise. The shares not eligible for immediate resale will remain eligible for sale pursuant to Rule 144, subject only to the volume limitation and manner of sale restrictions of Rule 144. In addition, the shares of common stock issuable upon the exercise of outstanding options have been registered under the Securities Act and, upon exercise, will be eligible for immediate resale. The sale of shares of our common stock could adversely affect the prevailing market price of our common stock. SOME OF OUR SHAREHOLDERS HAVE REGISTRATION RIGHTS THAT COULD DILUTE OUR COMMON STOCK. Pursuant to an agreement between us and bioMerieux, in the event we elect to register any of our equity securities under the Securities Act for our shareholders, subject to certain exceptions and limitations, we are obligated to use our best efforts to include any shares requested to be registered by bioMerieux in the registration if the registration occurs after September 30, 2001. We are required to bear all registration expenses incurred in connection with the registration of these shares. We may have an obligation to pay the costs incurred by Robert J. Hennessey in connection with an underwritten public offering of some or all of Robert J. Hennessey's shares of common stock. 13 FORWARD-LOOKING STATEMENTS This prospectus and the documents we have filed with the Securities and Exchange Commission contain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Therefore, we do not intend to pay any cash dividends on our common stock in the foreseeable future. Certain of our equipment lease facilities prevent us from paying any cash dividends while there are amounts outstanding under these facilities without consent of the lessor. 15 BUSINESS OF GENOME THERAPEUTICS OVERVIEW We are a leader in the commercialization of genomics-based drug discovery. Through the identification of genes and the characterization of the function of those genes, we are seeking to accelerate the discovery and development of products to treat and diagnose a number of diseases. The United States government has selected us to participate in a number of government sponsored gene discovery programs, including the Human Genome Project and the Mouse Genome Sequencing Network. Our depth of experience in the genomics field has permitted us to emerge as a leader in creating industrial scale genomics tools for product development. Our tools include: - high-throughput sequencing - sequence finishing - bioinformatics - functional genomics - assay development We have combined our genomics tools into an integrated platform of highly automated technologies which allows us to rapidly generate high quality genomic information that we use to identify and validate targets for the development of new therapeutic and diagnostic products. We concentrate our product discovery efforts in two principal areas: human diseases believed to have a significant genetic component and infectious diseases caused by pathogens, including bacteria and fungi. We are pursuing the discovery of products based on our genomic discoveries both through strategic alliances with corporate partners and through internal research programs. In the area of human diseases, we have alliances with Wyeth-Ayerst to develop treatments for osteoporosis and with Schering-Plough to develop treatments for asthma. In the area of infectious diseases, we have ongoing collaborations with Schering-Plough to develop treatments for drug resistant bacterial infections, including STAPH. AUREUS, and to develop novel anti-fungals. We are working with AstraZeneca to develop treatments for ulcers caused by H. PYLORI. We have also partnered with bioMerieux to develop diagnostics for infectious diseases. As part of our emerging businesses, we are continuing to invest in our internal infectious disease franchise and build our pharmacogenomics program. In addition to our drug discovery programs, we have formed the GTC Sequencing Center to provide industrial scale, high quality customized sequencing services to pharmaceutical companies and biotechnology companies on a contract basis. Since the launch of the GTC Sequencing Center in July 1999, we have entered into 11 sequencing contracts with pharmaceutical and biotechnology companies and other research institutions, in addition to our work in the United States government's genomics programs. We are also seeking to increase access to our PathoGenome Database beyond our initial six subscribers by making it available to a broader spectrum of users. SCIENTIFIC BACKGROUND Genes define the inherited characteristics of an organism and are found in all living cells, including human, animal and pathogen cells. Each gene is responsible for producing a specific protein that performs a specific biological function in the body. A variety of factors cause human disease, including genetic defects, pathogens and environmental factors, with many of the most common life threatening and chronic diseases believed to have a genetic component. Genetic defects in humans may lead to overproduction or underproduction of proteins, resulting in disease. Consequently, the identification and characterization of genes and the proteins associated with these genes may lead to new therapies and diagnostic tests. In the case of diseases caused by pathogens, the identification and characterization of the genes essential to the survival of the pathogen may lead to the development of new drugs and vaccines to combat the pathogen. An individual's genetic makeup may also predetermine his or her 16 susceptibility to types of treatments or specific drugs. This genomic profile may permit the application of pharmacogenomics to optimize the efficacy or minimize the toxicity of novel or existing drugs. While efforts to identify and characterize the genes responsible for various diseases by the Human Genome Project and genomics companies have resulted in the generation of tremendous amounts of gene sequence and other genetic information, the discovery of new products based on this information has been limited. The U.S. government and several private companies are spending enormous resources toward the completion of the entire human genomic sequence containing over 100,000 gene pairs. This has led to a further effort to identify those genetic abnormalities or mutations that have a relationship to a specific disease state. These mutations add millions of potential genetic sequence combinations to the universe of potential drug targets. Identifying genes that cause or are associated with a specific disease and determining how those genes contribute to the disease has been a formidable challenge. Therefore, industrialized discovery technologies that can convert this large amount of genomic data into actual drug candidates is critical to translate these early-stage discoveries into actual treatments for human disease. An integrated suite of technologies, tools and data management and analysis capabilities is required to bridge this gap between data inputs and drug candidates. We have designed an integrated platform of highly automated, industrial scale technologies that permits us to rapidly analyze and draw conclusions from high quality genomic information. Our approach will allow us and our collaborators to effectively use genomic information to identify and validate targets that will then be successfully developed into novel therapeutics and diagnostic products. OUR STRATEGY We intend to use our integrated suite of genomics technologies to accelerate drug discovery both in our internal research programs and those of our collaborators. The key elements of our strategy include: ESTABLISH AND EXPAND ALLIANCES WITH INDUSTRY LEADERS IN SPECIFIC DISEASES We believe our current alliances with Wyeth-Ayerst, Schering-Plough, AstraZeneca, and bioMerieux, all industry leaders in their fields, provide us the best opportunity to convert our genomics expertise into product opportunities. We have met or exceeded our development schedule with all of our collaborators and will continue to deliver high quality genomic information on a timely basis to our collaborators. We will also seek to expand these alliances. We will also seek to enter into additional alliances with partners that have franchises in the treatment of major disease indications. We believe companies that have major research efforts and/or commercial products focused on a particular disease will be motivated to utilize genomic information to develop novel products that will allow them to maintain their market leadership position. USE OUR CONTRACT SEQUENCING BUSINESS TO GENERATE NEAR-TERM REVENUE AND BUILD RELATIONSHIPS WITH POTENTIAL COLLABORATORS Our reputation for rapid, high quality sequencing has been recognized by the U.S. government, which has selected us as one of ten U.S. centers for the Human Genome Project and one of five initial centers for the Mouse Genome Sequencing Network, and the only commercial entity involved in either project. In order to leverage fully our sequencing capabilities, in July 1999 we launched the GTC Sequencing Center to provide high quality, industrial scale customized sequencing services to pharmaceutical and biotechnology companies on a contract basis. We intend to use our contract sequencing business to generate near-term revenues and as an opportunity to familiarize customers with our genomics capabilities. In this way, our customized sequencing business may permit us to broaden our business relationships with our biotechnology and pharmaceutical customers, extending our relationships into more comprehensive strategic alliances. 17 LEVERAGE PATHOGENOME DATABASE We intend to maximize the potential of our PathoGenome Database. In 1997, we introduced the PathoGenome Database, a database containing both proprietary and publicly available genetic information on over thirty microbial organisms. To date we have commercialized the PathoGenome Database through non-exclusive subscriptions to pharmaceutical companies, including Aventis (formerly known as Hoechst Marion Roussel), Bayer, Bristol-Myers Squibb, Schering-Plough and Scriptgen Pharmaceuticals. Going forward, we intend to increase access to the PathoGenome Database by making it available to a larger universe of scientific and other users. We are pursuing alliances that will facilitate broader access to our PathoGenome Database. We believe this will increase the value of the PathoGenome Database by enhancing our exposure to scientific and pharmaceutical researchers and solidifying our reputation as a leader in pathogen genomics. EXPAND INTERNAL DEVELOPMENT PROGRAMS IN PHARMACOGENOMICS AND INFECTIOUS DISEASES We have ongoing internal development programs to build businesses in pharmacogenomics and expand our existing infectious disease franchise. In the pharmacogenomics area, we intend to form alliances with pharmaceutical and biotechnology companies to use our integrated platform of technologies to detect genetic variations that affect individual drug response. We believe that our technology will allow us both to select the best leads for drug development and to "rescue" drugs that have foundered. In the field of infectious diseases, we plan to expand our internal program to pursue leads for novel drugs based upon the results of our genomic research. PHARMACEUTICAL AND DIAGNOSTIC PROGRAMS We are building on our experience and knowledge in high-throughput sequencing, bioinformatics, disease gene identification and functional genomics to identify and characterize genes that we believe will lead to discoveries of new or improved drugs, vaccines or diagnostic products that represent significant commercial opportunities. The following table describes our existing collaborations with pharmaceutical companies to develop drugs to treat human and infectious diseases and to develop infectious disease diagnostics. 18 PHARMACEUTICAL AND DIAGNOSTIC PRODUCT PROGRAMS PARTNER PROCEEDS RECEIVED AS DISEASE INDICATION (DATE OF AGREEMENT) STATUS OF ALLIANCE OF FEBRUARY 26, 2000 POTENTIAL PROCEEDS* - ------------------ ------------------- ------------------- -------------------- ------------------- Osteoporosis Wyeth-Ayerst Functional studies $1.3 million $118.0 million Division of to confirm identity American Home of target gene Products ongoing; project (December 1999) planning commenced Asthma Schering-Plough Identification of $25.5 million $75.9 million (December 1996) candidate genes ongoing; research program extended to December 2001 Ulcers AstraZeneca Target $13.5 million $23.3 million (September 1995) identification completed; program transferred to AstraZeneca for pre-clinical testing Drug Resistant Schering-Plough Validated targets $18.8 million $42.8 million Bacterial (December 1995) and screening Infections assays transferred to Schering-Plough Fungal Infections Schering-Plough Targets identified $9.7 million $36.0 million (September 1997) for screening; research program extended to September 2001 Infectious Disease bioMerieux PathoGenome $5.4 million $6.2 million Diagnostics (September 1999) Database delivered; guaranteed in first identification of year (includes gene markers completed equity ongoing investment) - -------------------------- * Assumes receipt of all license fees, funded research and contingent payments for achieving milestones; excludes potential royalties OSTEOPOROSIS. Osteoporosis is a major health problem characterized by low bone mass that affects more than 200 million people worldwide and approximately one-third of post-menopausal women. In the U.S. alone, osteoporosis contributes to more than 1.5 million bone fractures per year. Estimated national direct expenditures for osteoporotic and associated fractures is $13.8 billion, and the cost is rising in the Unites States. Twin and family studies suggest a strong genetic component to the disease. Under a collaboration with Creighton University of Omaha, Nebraska, we have gained access to data from related individuals identified by Creighton that exhibit high bone mass. We believe the identification of genes regulating bone density and disease progression will lead to the discovery of novel drugs for treating osteoporosis by increasing bone mass, as well as the development of diagnostic tests. In December 1999, we formed an alliance with Wyeth-Ayerst to develop drugs to treat osteoporosis based on our genetic research. Wyeth-Ayerst is a leader in the field of women's health with a broad array of products, including Premarin-Registered Trademark-, a leading estrogen replacement therapy. As of February 26, 2000, we had received payments of $1.3 million under this alliance and have rights to 19 receive, subject to the achievement of milestones, up to an additional $116.7 million in license fees, milestone payments and research support, as well as royalties on sales of any products developed. Under this alliance, we are carrying out functional studies to confirm the identity of target genes. ASTHMA. Asthma affects over 155 million people worldwide according to the World Health Organization. The incidence appears to be rising dramatically worldwide; in the United States, the incidence has doubled over the past two decades. Asthma affects approximately 4% to 10% of the United States population, and accounts for $12.6 billion in direct and indirect costs. Published research suggests that multiple genetic factors as well as environmental influences play a role in the disease. We believe that the asthma genes that we have identified will facilitate the development of superior diagnostics and novel drugs. In December 1996, we formed an alliance with Schering-Plough to use our disease gene identification strategies to identify genes involved in the origin of asthma. Schering-Plough has extended our alliance through December 2001. Schering-Plough is a leader in the field of allergy and respiratory care products, with products such as Afrin-Registered Trademark- nasal spray, the leading product in the branded nasal spray market, and the Claritin-Registered Trademark- line of antihistamines, which generated $2.3 billion of sales in 1998. As of February 26, 2000, we had received payments of $25.5 million under this alliance and have rights to receive, based on attainment of milestones, an additional $50.4 million of payments as well as potential royalties. We are using our proprietary genomics tools, bioinformatics and high-throughput sequencing to identify candidate genes believed to be involved in the development of asthma in certain individuals. ULCERS. H. PYLORI infection affects an estimated 30% of the United States population, causing more than 5 million cases of peptic ulcer disease per year. Industry sources estimate that the market for ulcer disease products worldwide was $11.5 billion in 1999. The pathogen H. PYLORI is believed to be responsible for 90% of duodenal ulcers, the most common type of ulcer, and approximately 80% of gastric peptic ulcers. The World Health Organization has estimated that H. PYLORI is responsible for 550,000 new cases of stomach cancer per year worldwide. Using our sequencing technology, we completed the random sequencing and finishing of the genome of H. PYLORI. The most common forms of treatment of H. PYLORI, antibiotics and antisecretory drugs, do not eradicate H. PYLORI. We believe that drugs targeted at genes essential to the survival of H. PYLORI will provide novel treatments for peptic ulcers. In September 1995, we formed an alliance with AstraZeneca to identify genes critical to the survival of H. PYLORI and proteins on the surface of the bacterium that we believe to be likely targets for drugs and vaccines. AstraZeneca is a leader in the field of products to treat peptic ulcer disease. Its anti-ulcer drug, Prilosec-Registered Trademark-, was the world's biggest selling prescription drug in 1999 with sales of $5.9 billion. As of February 26, 2000, we had received payments of $13.5 million under this alliance and have rights to receive, based on attainment of milestones, an additional $9.8 million of payments in addition to potential royalties. As of August 1999, we had completed our research obligations under this alliance and had turned over validated drug and vaccine targets to AstraZeneca for pre-clinical testing. DRUG RESISTANT BACTERIAL INFECTIONS. Infectious diseases remain the world's leading cause of premature death. Each year approximately 2 million patients in the U.S. develop antibiotic resistant infections while being treated in hospitals. These infections are caused by antibiotic resistant organisms, many of which have multiple antibiotic resistance. Industry sources estimate that the market for anti-infective products worldwide was $58 billion in 1999. The pathogen STAPH. AUREUS is a common cause of skin, wound and blood infections. STAPH. AUREUS infections are typically treated with antibiotics. In recent decades, the incidence of STAPH. AUREUS infections that are resistant to traditional antibiotic treatments has risen. Using our high-throughput sequencing capabilities, we have sequenced the genome of antibiotic-resistant STAPH. AUREUS. We believe that drugs targeted at genes essential to the 20 survival of STAPH. AUREUS will provide novel treatments for skin, wound and blood infections contracted in hospitals. In December 1995, we formed an alliance with Schering-Plough to identify and validate gene targets for the development of drugs to target STAPH. AUREUS and other pathogens that have become resistant to current antibiotics. Schering-Plough is an established participant in the anti-infective market, and a leader in the utilization of genomics to discover novel anti-infective products. As of February 26, 2000, we had received payments of $18.8 million under this alliance and have rights to receive, based on attainment of milestones, an additional $24.0 million of payments in addition to potential royalties. To date, we have delivered numerous validated drug targets to Schering-Plough for pre-clinical testing. Schering-Plough is continuing to screen validated targets to identify drug candidates. FUNGAL INFECTIONS. In the past twenty years, we have seen dramatic changes in the pattern of fungal infections in humans. These pathogens have assumed a much greater importance because of their increasing incidence in immunocompromised patients, such as AIDS patients, transplant recipients, cancer patients and other groups of immunocompromised individuals. Increased international travel and misuse of antimicrobial agents have also contributed to this trend and the emerging resistance to certain treatments. Industry sources estimate that the market for prescription antifungal drugs worldwide was approximately $1.8 billion in 1999, with non-prescription fungal treatments adding significantly to overall market size. Currently, there are a limited number of antifungals available for use against hospital related fungal infections, and many of the products currently on the market have serious side effects. We believe that drugs targeted at genes that are essential to the survival of fungal pathogens will provide novel and effective treatments for fungal infections. In September 1997, we formed an alliance with Schering-Plough to use our high-throughput sequencing capabilities and genomic tools to identify new, validated fungal targets for the development of drugs to treat fungal infections. Schering-Plough has extended our alliance through September 2001. Schering-Plough is a leader in the field of drugs targeted against fungal infections, with market leading products such as the Lotrimin AF-Registered Trademark- and Tinactin-Registered Trademark- lines of topical antifungals. As of February 26, 2000 we had received payments of $9.7 million under this alliance and have rights to receive, based on attainment of milestones, an additional $26.3 million of payments in addition to potential royalties. In the course of the program, we identified multiple essential fungal genes, and in October 1999, we delivered multiple assays for validated targets to Schering-Plough for drug candidate screening. INFECTIOUS DISEASE DIAGNOSTICS. The World Health Organization estimates that more than 17 million people die of an infectious disease each year, with many of those infections acquired in hospitals. There has been a global resurgence of infectious diseases, including the identification of new pathogens, the re-emergence of old infectious agents and the rapid spread of resistance to anti-infective agents. The ability to rapidly identify the specific microorganisms involved in disease is becoming increasingly important and complex, providing challenges and opportunities for infectious disease testing. Highly sophisticated and versatile methods are needed to identify a larger and more diverse list of pathogens, including variants with drug resistant characteristics. According to industry sources, the global market for IN VITRO diagnostics for infectious disease was approximately $3.2 billion in 1997. In September 1999, we entered into a strategic alliance with bioMerieux to develop, manufacture and sell IN VITRO pathogen diagnostics for human clinical and industrial applications. A privately held company based in France, bioMerieux is one of the top 10 diagnostics companies in the world and the leader in the field of microbiology. We will receive a minimum of $6.2 million in the first year under this alliance. As of February 26, 2000, we had received payments of $5.4 million, including a completed equity investment, and have rights to receive future milestone payments and royalties based upon successful commercialization of diagnostic products. We have delivered the PathoGenome Database to bioMerieux and are currently identifying gene markers that can be employed in diagnostic product development. 21 GENOMIC SEQUENCING AND DATABASES We launched the GTC Sequencing Center in July 1999, capitalizing on our sequencing strengths by providing sequencing services to customers on a contractual basis. Our business focuses on providing customized sequencing services to biotechnology companies and pharmaceutical companies that need industrial scale, high quality customized sequencing capability. We have extensive experience in high-throughput sequencing. With approximately fifty full-time sequencers on staff and our highly automated sequencing center operating twenty-four hours per day, seven days per week, we are currently sequencing over 10 million base pairs (10 megabases) per day. The U.S. government has recognized the quality of our sequencing work by naming us as one of ten U.S. centers for the Human Genome Project and one of five initial centers for the Mouse Genome Sequencing Network. We are the only commercial entity selected for either project. Since the launch of the GTC Sequencing Center in July 1999, we have entered into sequencing contracts with thirteen commercial, government and research customers, including the companies and institutions that we are able to disclose publicly as follows: SELECTED CONTRACT SEQUENCING CUSTOMERS AstraZeneca Aventis Biogen Cubist Pharmaceuticals Memorial Sloan-Kettering Cancer Center Phylos Human Genome Project Mouse Genome Sequencing Network Cancer Research Center--Queen's University, Ireland The GTC Sequencing Center is a key component of our strategy because it provides us with near-term revenues and the ability to defray a portion of the expenses associated with our sequencing operations. We believe the GTC Sequencing Center permits us to establish business relationships with a broader variety of participants in the biotechnology and pharmaceutical industries, which may lead to more comprehensive strategic alliances. PATHOGENOME DATABASE. In 1997, we introduced to the market the PathoGenome Database, a database consisting of proprietary and publicly available genetic information from over thirty microbial organisms, including organisms responsible for the most prevalent bacterial infections. The PathoGenome Database provides subscribers with non-exclusive access to a large volume of highly organized and functionally annotated sequence information related to some of the most medically important microbial organisms and fungi. We designed the PathoGenome Database to be accessed at the client site using our proprietary bioinformatics software. It enables researchers to search for new genes among multiple pathogens and cross-reference genomic information for the development of new anti-infective products. The following six companies have subscribed to the PathoGenome Database: SUBSCRIBERS TO PATHOGENOME DATABASE Aventis Bayer bioMerieux Bristol-Myers Squibb Schering-Plough Scriptgen Pharmaceuticals 22 We received payments for access to the PathoGenome Database for a specified term for all subscribers, and we have rights to receive royalties from future product sales if the subscriber develops a product based on proprietary information in the PathoGenome Database. We are currently exploring opportunities to broaden access to the PathoGenome Database by commercial and academic researchers from all over the world. We are considering alliances to facilitate this access and extend the market for our PathoGenome Database. EMERGING BUSINESSES Expenditures for new drug development have been steadily increasing and there continues to be a shortfall in the number of new pharmaceutical product introductions in the market. In addition, adverse drug events together with poor side effect profiles may limit the success of existing pharmaceuticals. We are seeking to employ our platform of genomics technologies to develop new, more effective drugs through both our pharmacogenomics and infectious disease programs. PHARMACOGENOMICS. Understanding the differences in responses to drug therapy related to single nucleotide polymorphisms, commonly referred to as SNPs, in the genetic make-up of individuals can play a significant role in improving the overall safety and efficacy of drugs. We have developed a highly accurate and efficient platform to support our pharmacogenomics program. We are using our technology platform, based on our high quality, high throughput sequencing capability and a proprietary SNP screening assay, to search for genetic causes responsible for variations among individuals in response to drugs. As a first step in our pharmacogenomics program we have entered into a contract with a biotechnology company to determine genetic variations to validate that company's target. We plan to work with collaborators to identify more appropriate patient populations using pharmacogenomics to enable the development of more effective, safer drugs and the recovery of promising drugs that could succeed in trials using pre-selected populations based upon genetically determined responsiveness. INFECTIOUS DISEASES. We are mining the sequence information contained in our PathoGenome Database to identify genes that are novel targets and, as a result, good candidates for internally funded infectious disease drug development. Using our proprietary functional genomics technology, our scientists have been able to discover genes that are essential for the survival of pathogenic organisms. This technology, when combined with our bioinformatics capabilities, enables us to identify broad-spectrum microbial targets that are essential in bacteria. Thus, our gene discovery approach generates validated microbial targets that possess both selectivity and specificity, which are ideal attributes for drug intervention. These targets serve as the basis for our emerging internal drug discovery efforts. In this regard, we have drawn upon our strengths in microbial genetics to develop both biochemical and cell based assays for these targets for use in high-throughput compound screens. We will continue to pursue joint ventures similar to our joint venture with ArQule, a combinatorial chemistry company, where we have screened ArQule's proprietary chemical libraries against our assays to identify small molecule anti-infectives. In addition, we intend to build internal capabilities through the acquisition of novel compound libraries, technologies and/or products. It is anticipated that these efforts will lead to the further growth of our own infectious disease franchise. We may enter into alliances with other companies to engage in the development, commercialization and marketing of leads identified through our internal infectious disease program. Under certain circumstances, we may have an obligation to give Schering-Plough a right of first negotiation to develop certain of our infectious disease related discoveries with us if we decide to seek a third party collaborator to develop such discovery. OUR TECHNOLOGY We have created an integrated high quality platform of genomic technologies that can identify and validate novel targets for drug, vaccine and diagnostic product development. Proteins, expressed by genes, are the targets of most current drugs. We believe identification of human disease genes and genes essential to the functioning of pathogens should enable the development of new drugs and other 23 products. We believe our technology platform will allow us to accelerate drug, vaccine and diagnostic development for both our human and infectious disease directed programs. Our integrated technology platform includes high quality, industrial scale sequencing and sequence finishing, bioinformatics, functional genomics technologies, and assay development. The following chart illustrates the principal steps in the discovery and development of novel targets for drug development using genomic-based discovery tools. As demonstrated by the chart, our integrated platform of technologies spans the drug discovery landscape, from gene identification to compound optimization. DRUG DISCOVERY & DEVELOPMENT PROCESS [LOGO] HIGH-THROUGHPUT SEQUENCING. We have developed a high-quality, industrial scale process for sequencing. The GTC Sequencing Center utilizes a fully automated process which makes use of DNA sequencing instruments and computers to sequence and analyze genes. Our current sequencing production is over 10 million base pairs (10 megabases) of raw sequence daily. We maintain high quality standards for all steps of our sequencing process by strictly controlling the quality of the raw data generated. Using our technology, we have sequenced and continue to sequence the genomes of bacterial and fungal pathogens and various regions of the human, mouse and other genomes. SEQUENCE FINISHING. Finishing is the final step to organizing the genomic data once the the majority of the sequence information has been generated. Finishing is necessary because the individual clones sequenced contain small, randomly selected fragments of the complete genome. We assemble these fragments using sophisticated proprietary computer software that identifies overlapping regions and arranges the fragments into large contiguous regions. We also employ a directed sequencing approach in order to specifically target and obtain sequences for the missing regions to facilitate completion of the full genome sequence. We have developed a proprietary finishing platform that utilizes integrated computational and biochemical approaches to specify the required quality of the end-product sequence and then directs the process to achieve the desired quality level. As a result of our emphasis on quality, we currently have a finished data accuracy of 99.99%. 24 BIOINFORMATICS. Vast amounts of data result from DNA sequencing, finishing, microarray and other genomic technologies that we employ. In order to determine the biological significance and function of the genomic data that we compile, it must be organized, managed, and analyzed. Bioinformatics involves the use of computers, software, and databases to track, process, store, retrieve and analyze data generated by genomic research. We were one of the first companies to develop a significant bioinformatics capability due to our early work in large-scale genetic linkage and sequence analysis. A central focus of our current bioinformatics program is the development and application of genomic data mining and visualization software to strengthen our gene and drug discovery programs. The objective of our bioinformatics program is to accelerate the discovery of genes and the determination of their function. FUNCTIONAL GENOMICS. Functional genomics is the process of assigning biochemical functions and disease roles to genes. In the target discovery and validation stages of our pharmaceutical and diagnostic programs, functional genomics confirms that specific gene targets are appropriate for the development of pharmaceutical, vaccine, or diagnostic products. We have developed a number of technologies to accelerate the functional analysis of important disease genes, including gene expression, micro arrays, high throughput protein-protein interaction technologies and gene knockouts. When we combine our expertise in bioinformatics with these technologies, we bridge the gap between gene discovery and drug discovery. ASSAY DEVELOPMENT. After determining that a gene target is susceptible to treatment by a small molecule drug and, in the case of a pathogen gene, essential for the survival or virulence of a pathogen, we then develop screening assays or tests for chemical compounds which interact with these targets. The development of screening assays involves confirming the consistency of the validated target under conditions that are pertinent to its viability for treatment of humans. Following successful completion of the assay development stage, we are then able to identify chemical compound leads that could enter into clinical testing and that could ultimately result in a marketable drug. STRATEGIC ALLIANCES The primary focus of our commercialization strategy is to pursue strategic alliances with pharmaceutical companies that are leaders in particular fields for the development and commercialization of products resulting from our genomic discoveries. This strategy provides us access to the substantial resources and product development expertise of our partners and permits us to benefit financially from the commercialization of products based on our gene discoveries, without incurring the substantial costs required for pharmaceutical product development and commercialization. We generally expect to license (either exclusively or non-exclusively) to a partner most rights in a specific field to therapeutic products and vaccines and, depending upon the gene, diagnostic products that may be developed by the partner from the particular genetic information that we provided to the partner. In exchange for a license to our genetic research data and other information in a certain area, we are typically entitled to receive a combination of: - up-front license fees - research funding - milestone payments - royalty payments on product sales To date, we have entered into strategic alliances with Wyeth-Ayerst, Schering-Plough (three distinct disease focused alliances), AstraZeneca, and bioMerieux. We also have government collaborations specifically focusing on our gene sequencing capability. Our strategic alliances are described in more detail below. 25 WYETH-AYERST/AHP. In December 1999, we entered into a strategic alliance with Wyeth-Ayerst to develop novel drugs and other therapeutics for the prevention and treatment of osteoporosis. Our alliance will focus on developing drugs utilizing targets based on the characterization of a gene associated with a unique high bone mass trait, the mirror image of osteoporosis. Under the agreement, we granted Wyeth-Ayerst an exclusive worldwide license to make, use and sell pharmaceutical and vaccine products based on this gene in the field of osteoporosis. We have commenced functional studies to confirm the identity of the gene responsible for the high bone mass trait. We are focusing on the validation of gene targets in preparation for drug development utilizing the extensive experience and capabilities of Wyeth-Ayerst in bone research. Under this agreement, Wyeth-Ayerst has agreed to pay us up to $118 million in up-front licensing fees, funded research and contingent payments for achieving milestones. We also have the right to receive royalty payments on Wyeth-Ayerst's sales of products based on technologies they have licensed from us under the agreement. As of February 26, 2000, we had received payments of $1.3 million under this alliance. Wyeth-Ayerst has the right to terminate the alliance prior to its completion in certain circumstances when we are not in breach under the agreement, including if Wyeth-Ayerst determines that the prospects for drug discovery under the alliance are minimal, or if Wyeth-Ayerst determines that third party intellectual property rights are likely to impair development or commercialization of a product under this alliance. In the event of such a termination all licensed intellectual property rights revert to us. Certain technologies licensed to Wyeth-Ayerst will be exclusively licensed by us from Creighton University and sublicensed to Wyeth-Ayerst. We will owe Creighton royalties under the license. SCHERING-PLOUGH. We have three strategic alliances in place with Schering-Plough, focusing on asthma, drug resistant bacterial infections and fungal infections. ASTHMA. In December 1996, we established a strategic alliance with Schering-Plough to use our genomics research abilities to help discover new pharmaceutical products to treat asthma. In May 2000, Schering-Plough extended this alliance through December 2001. Under this alliance, we employ our high-throughput disease gene identification, bioinformatics, and genomics sequencing capabilities to identify genes and associated proteins that Schering-Plough can use to develop pharmaceuticals and vaccines for treating asthma. We are using our proprietary genomics tools, bioinformatics and high-throughput sequencing to identify candidate genes believed to be involved in the development of asthma in certain individuals. The research phase of this alliance is scheduled to end in December 2001. Under the agreement, Schering-Plough agreed to pay us up to $75.9 million in initial license fees, funded research and contingent payments for achieving milestones. Of the total potential payments, approximately $31.4 million represents license fees and funded research payments and $44.5 million represents milestone payments based on achievement of research and product development objectives. We have achieved a number of milestones under this agreement and have received payments as of February 26, 2000 of $25.5 million. In November 1998, Schering-Plough accelerated the program to increase funding and development in earlier years. The agreement also obligates Schering-Plough to pay us royalties based upon any sales of therapeutic products developed from this collaboration. Under the agreement, we granted Schering-Plough an exclusive worldwide license to make, use and sell pharmaceutical and vaccine products that may result from this collaboration. Under certain circumstances, we may have an obligation to give Schering-Plough a right of first negotiation to develop with us certain of our asthma related discoveries if we decide to seek a third party collaborator to develop such discovery. We retain the rights to make, use and sell diagnostic products resulting from our research under the agreement. 26 DRUG RESISTANT BACTERIAL INFECTIONS. In December 1995, we entered into a strategic alliance with Schering-Plough to identify and validate gene targets for the development of drugs to target STAPH. AUREUS and other pathogens that have become resistant to current antibiotics and are a primary cause of hospital-based infections. In March 1998, Schering-Plough elected to extend the research program through March 31, 2000. In August 1999, we delivered numerous validated drug targets to Schering-Plough for pre-clinical testing. Under this agreement, Schering-Plough has agreed to pay us up to $42.8 million in initial license fees, funded research and contingent payments for achieving milestones. We have achieved all of the research milestones under this agreement and have received payments of $18.8 million as of February 26, 2000. Subject to the achievement of additional product development milestones, Schering-Plough has agreed to pay us up to an additional $24 million in milestone payments. As part of this program, we granted Schering-Plough exclusive worldwide access to our proprietary STAPH. AUREUS genomic sequence database to make, use and sell pharmaceutical and vaccine products based on these databases and the technology developed during the course of the research program. We will be entitled to receive royalties on Schering-Plough's sale of therapeutic products and vaccines developed using the technology we licensed to Schering-Plough. We also granted Schering-Plough a non-exclusive license to use our bioinformatics systems for Schering-Plough's internal use in connection with the genomic databases licensed to Schering-Plough under our agreement and other genomic databases Schering-Plough develops or acquires. Subject to certain limitations, we retain the rights to make, use, and sell diagnostic products developed utilizing our genomic database licensed to Schering-Plough and the technology developed during the course of the research program. The research phase of this alliance is scheduled to end in March 2000. FUNGAL INFECTIONS. In September 1997, we established our third strategic alliance with Schering-Plough to use genomics to discover and develop new pharmaceutical products to treat fungal infections. In December 1999, Schering-Plough extended this alliance with us through September 2001. The alliance calls for us to use our bioinformatics, high-throughput sequencing and functional genomics capabilities to identify and validate genes and associated proteins as drug discovery targets that Schering-Plough can utilize to develop novel antifungal treatments. Schering-Plough receives exclusive access to certain genomic information developed in the collaboration related to two fungal pathogens, CANDIDA ALBICANS and ASPERGILLUS FUMIGATUS. In October 1999, we delivered multiple assays for validated targets to Schering-Plough, and Schering-Plough began high-throughput screening for new drug candidates. The research phase of this alliance is scheduled to end in September 2001. Under this agreement, Schering-Plough has agreed to pay us up to $36 million in initial license fees, funded research and contingent payments for achieving milestones. We have achieved all of the research milestones under this agreement and have received payments of $9.7 million as of February 26, 2000. Schering-Plough receives the exclusive worldwide right to make, use, and sell pharmaceutical products to treat human and animal diseases based on the technology developed during the course of the research program. We will be entitled to receive royalties on Schering-Plough's sale of therapeutic products and vaccines developed using the technology we licensed to Schering-Plough. Subject to certain limitations, we retain the rights to make, use and sell diagnostic products resulting from our research under the agreement. ASTRAZENECA. In August 1995, we entered into a strategic alliance with AstraZeneca to develop drugs, vaccines and diagnostic products effective against peptic ulcers or any other disease caused by H. PYLORI. In August 1999, we successfully concluded our research portion of the alliance and transitioned the program into AstraZeneca's pipeline for pre-clinical testing. In the course of our research, we 27 identified and validated a number of undisclosed targets and vaccine antigens. We delivered these targets, as well as screening assays, to AstraZeneca for high-throughput drug candidate screening. Under the alliance, we also granted AstraZeneca exclusive access to our H. PYLORI genomic sequence database. Under this agreement, AstraZeneca has agreed to pay us up to $23.3 million in license fees, funded research and contingent payments for achieving milestones. We have received approximately $13.5 million in license fees, milestone payments and research funding under this agreement through Feburary 26, 2000. Under the alliance, AstraZeneca holds the exclusive worldwide rights to make, use and sell products based on H. PYLORI technology licensed to AstraZeneca. We have rights to receive royalties on AstraZeneca's sale of any products protected by patent claims that we have licensed exclusively to AstraZeneca pursuant to the agreement, or resulting from a discovery enabled by our genomic database licensed to AstraZeneca. AstraZeneca has the rights to make, use and sell diagnostic products resulting from our research under the agreement. BIOMERIEUX. In September 1999, we entered into a strategic alliance with bioMerieux to develop, manufacture and sell IN VITRO pathogen diagnostics for human clinical and industrial applications. Under the terms of the alliance, we granted bioMerieux all rights not previously granted to others in the area of pathogen genetics for the development of diagnostic products. We have delivered the PathoGenome Database to bioMerieux and are currently identifying gene markers that can be employed in diagnostic product development. Under this collaboration, bioMerieux has guaranteed us payments of at least $6.2 million in the first year, which includes a $3.8 million equity investment that has been completed. bioMerieux also agreed to fund research in the area of infectious disease diagnostics for four years. We will receive future milestone payments and royalties based upon successful commercialization of diagnostic products. As of February 26, 2000, we had received payments of $5.4 million under this alliance, including the completed equity investment. GOVERNMENT COLLABORATIONS Since 1989, various agencies of the United States government have awarded us a number of research grants and contracts under government genomics programs. The scope of our research covered by grants and contracts includes technology development, sequencing production, technology automation projects and disease gene identification projects. These programs strengthened our genomics technology base and increased the number and enhanced the expertise of our scientific personnel. As of February 26, 2000, we had approximately $25.1 million of government research grants and contracts outstanding under which we had not yet completed all of the services. These grants and contracts call for us to perform services through October 2002. These programs are subject to annual appropriations by the government based upon the availability of government funds and our achievement of certain milestones. The government may discontinue or reduce our funding at any time. In July 1999, the government named us one of ten funded DNA sequencing centers in the U.S. for the international Human Genome Project. The government based the award on a peer review process that evaluated our industrial scale sequencing facility for production capacity, cost effectiveness and quality standards. We are the only commercial entity to have been chosen to participate in the project. We will participate in an international consortium in a full-scale effort to sequence the human genome. We will receive funding from the NHGRI of up to $15.6 million over a three-year period of which $5.0 million is guaranteed for the initial twelve months. In October 1999, the government named us as one of five initial centers in the Mouse Genome Sequencing Network. The government based the award on a peer review process that evaluated our 28 industrial scale sequencing facility for production capacity, cost effectiveness and quality standards. We are the only commercial entity to have been chosen to participate in deciphering the genetic makeup of the mouse. We will receive funding from the NHGRI of up to $12.9 million over a three-year period of which $2.4 million is guaranteed for the initial seven months. Under both these research contracts, the government has ownership rights to the data, clones, genes and other material derived from material furnished to us by the government. We have ownership rights in other inventions that we develop on our own under the contracts. PATENTS AND PROPRIETARY TECHNOLOGY Our ultimate commercial success depends in part on our ability to obtain patent protection on our methods, technologies and discoveries, including genes, proteins encoded by genes, patentable human single nucleotide polymorphisms or products based on genes or our proprietary gene technology. To that end, our policy is to protect our proprietary technology through patents, in spite of the fact that the current criteria for obtaining patent protection for partially sequenced genes and for genes are unclear. Our current strategy is to apply for patent protection upon the identification of a novel gene or novel gene fragment and pursue claims to these gene sequences as well as equivalent sequences, such as substantially homologous or orthologous sequences. If at the time of filing a patent application we have not characterized the biological function of a gene or gene fragment we supplement our patent filing as soon as additional biological function information about such gene or gene fragment becomes available. We have filed patent applications and will continue to do so with respect to a number of full-length genes and corresponding proteins and partial genes resulting from our pathogens program. Along with our collaborators, we file foreign counterparts of these U.S. applications within the appropriate time frames. Our patent applications seek to protect these full length and partial gene sequences and corresponding proteins, as well as equivalent sequences, and products derived from and uses of these sequences. There have been, and continue to be, intensive discussions on the scope of patent protection for gene fragments, single nucleotide polymorphisms, and full-length genes. In 1996, the U.S. Patent and Trademark Office issued guidelines limiting the number of nucleic acid sequences that can be covered in a single patent application. In addition, the U.S. courts continue to redefine and narrow the enforceable scope of claims to genes, gene fragments, and proteins. The U.S. PTO also issued new Utility Guidelines that address the requirements for demonstrating utility, particularly in inventions relating to human therapeutics, and proposed Written Description guidelines that address the amount of disclosure required to support claims to nucleotide sequences. Consequently, we continually must assess our patent applications to determine those that we can support for prosecution. While the guidelines do not require clinical efficacy data for issuance of patents for human therapeutics, the guidelines have been in effect for only a short period of time and it is possible that the U.S. PTO may interpret them in a way that could delay or adversely affect our ability or the ability of our collaborators to obtain patent protection. The biotechnology patent situation outside the United States is even more uncertain and is currently undergoing review and revision in many countries. We are free to apply for patents on the results of our research conducted with government funds. Under the government grants, subject to the limitations described below, we have exclusive ownership rights to any commercial applications of inventions that we first reduce to practice under the grants, including all gene discoveries and technology improvements created or discovered. We are under an obligation under some of the government grants to submit sequencing data resulting from the research to public databases within 24 hours from the date we generate such data and materials. The governmental grants also restrict us from applying for blanket patents on large numbers of human or mouse genes. In addition, the government has a statutory right to practice or permit others to practice 29 inventions that we first reduce to practice under a government grant or contract. In addition, under our government research contracts, the government has ownership rights in the data, clones, genes and other material derived from the material the government furnished to us. The patent positions of biotechnology and pharmaceutical companies are generally uncertain and involve complex legal and factual issues. No assurance can be given that any patent issued to or licensed by us or our collaborators will provide protection that has commercial significance. We cannot assure you that: - our patents will afford protection against competitors with similar compounds or technologies - our patent applications will issue - others will not obtain patents having claims similar to the claims in our patents or applications - the patents of others will not have an adverse effect on our ability to do business or - the patents issued to or licensed by us will not be infringed, challenged, opposed, narrowed, invalidated or circumvented Moreover, we believe that obtaining foreign patents may, in some cases, be more difficult than obtaining domestic patents because of differences in patent laws. We also recognize that our patent position may generally be stronger in the U.S. than abroad. In particular, we are aware that companies have published patent applications relating to nucleic acids encoding several H. PYLORI proteins and, in other disease programs, relating to genes for which we have found mutations of interest. If these companies are issued patents, their patents may limit our ability and the ability of our collaborators to practice under any patents that may be issued to us. Because of this, we or our collaborators may not be able to obtain a patent with respect to the genes of H. PYLORI or the value of certain other patents issued to us or our collaborators that are the subject of other collaborations may be limited. Also, even if a patent were issued to us or our collaborators, the scope of coverage or protection afforded to such patent may be limited. We also rely upon unpatented trade secrets and improvements, unpatented know-how and continuing technological innovation to develop and maintain our competitive position. We generally protect this information with confidentiality agreements that provide that all confidential information developed or made known to others during the course of the employment, consulting or business relationship shall be kept confidential except in specified circumstances. Agreements with employees provide that all inventions conceived by the individual while employed by us are our exclusive property. We cannot guarantee, however, that these agreements will be honored, that we will have adequate remedies for breach if they are not honored or that our trade secrets will not otherwise become known or be independently discovered by competitors. COMPETITION The biotechnology industry generally, and our human genetics and pathogen genetics and drug discovery programs specifically, are characterized by rapidly evolving technology and intense competition. Our competitors include pharmaceutical and biotechnology companies both in the United States and abroad. We believe that our principal competitors include Human Genome Sciences, Incyte Pharmaceuticals, Millennium Pharmaceuticals and Myriad Genetics. In addition, universities and other non-profit research institutions and United States and foreign government-sponsored entities are conducting significant research to identify and sequence genes. These entities are becoming more aggressive in their pursuit of patent protections and licensing arrangements. Many of these institutions and other consortia, such as the SNP Consortium, are also 30 working to make large amounts of genetic information publicly available, shrinking the pool of information available for proprietary protection. Many of our competitors have greater research and product development capabilities and financial, scientific, marketing and human resources than we do, and some competitors' human genome programs are more advanced than our program. Therefore, our competitors may succeed in identifying or sequencing genes or developing products earlier, in obtaining authorization from the FDA for products more rapidly and in developing products that are more effective than those proposed by us or our collaborators. Any potential products based on genes that we identify will face competition both from companies developing gene-based products and from companies developing other forms of diagnosis or treatment for the particular diseases. Accordingly, competition with respect to our technologies and product candidates is and will be based on, among other things: - our ability to create and maintain advanced technology - the speed with which we can identify and characterize the genes involved in human diseases - our ability to rapidly sequence the genomes of selected pathogens - our partners' ability to develop and commercialize therapeutic, vaccine and diagnostic products based upon our gene discoveries - our ability to attract and retain qualified personnel - our ability to obtain patent protection - our ability to develop proprietary technology or processes - our ability to secure sufficient capital resources to fund our research operations We also face increasing competition for strategic alliances with leading pharmaceutical and biotechnology companies. We cannot be certain that we will be able to obtain such strategic alliances in the future or that we will be able to obtain them on terms comparable with existing alliances. Competition among genetics companies is also increasing for access to unique data from related individuals that we employ to identify genes for specific human diseases. Our competitive position will also depend upon our ability to attract and retain qualified personnel, to obtain patent protection or otherwise develop proprietary product or processes, and to secure sufficient capital resources for the often substantial period between technological conception and commercial sales. Competitive disadvantages in any of these factors could materially harm our business and financial condition. GOVERNMENT REGULATION Regulation by governmental entities in the United States and other countries will be a significant factor in the development, manufacturing and marketing of any products that we or our collaborators develop. The extent to which such regulation may apply to us or our collaborators will vary depending on the nature of the product. Virtually all of our or our collaborators' pharmaceutical products will require regulatory approval by governmental agencies prior to commercialization. In particular, the FDA in the United States and similar health authorities in foreign countries subject human therapeutic and vaccine products to rigorous preclinical and clinical testing and other approval procedures. Various federal and, in some cases, state statutes and regulations also govern or influence the manufacturing, safety, labeling, storage, record keeping and marketing of human therapeutic and vaccine products. Obtaining these approvals and complying with appropriate federal and foreign statutes and regulations requires a substantial amount of time and financial resources. 31 The FDA regulates human therapeutic products in one of three broad categories: drugs, biologics, or medical devices. Products based on our technologies could potentially fall into all three categories. The FDA generally requires the following steps for pre-market approval of a new drug or biological product: - preclinical laboratory and animal tests - submission to the FDA of an investigational new drug application, or IND, which must become effective before clinical trials may begin - adequate and well-controlled human clinical trials to establish the safety and efficacy of the product for its intended indication - submission to the FDA of a marketing application; a new drug application, or NDA, if the FDA classifies the product as a new drug; or a biologics license application, or BLA, if the FDA classifies the product as biologic - FDA review of the marketing application and NDA or BLA in order to determine, among other things, whether the product is safe and effective for its intended uses We or our collaborators also may develop diagnostic products based upon the human or pathogen genes that we identify. We believe that the FDA is likely to regulate these diagnostic products as devices rather than drugs or biologics. The nature of the FDA requirements applicable to diagnostic devices depends on how the FDA classifies the diagnostic devices. The FDA most likely will classify a diagnostic device that we or our collaborators develop as a Class III device, requiring pre-market approval. Obtaining pre-market approval involves the following process, which may be costly and time-consuming: - pre-clinical studies - obtain an investigational device exemption to conduct clinical tests - filing a pre-market approval application - FDA approval Products on the market are subject to continual review by the FDA; therefore, subsequent discovery of previously unknown problems, or failure to comply with the applicable regulatory requirements may result in restricted marketing or withdrawal of the product from the market and possible civil or criminal sanctions. The FDA also may subject biologic products to batch certification and lot release requirements. To the extent that any of our products involve recombinant DNA technology, additional layers of government regulation and review are possible. Similarly, there are additional regulatory requirements for products marketed outside the United States governing the conduct of clinical trials, product licensing, pricing and reimbursement. MANUFACTURING AND MARKETING We do not expect to manufacture or market pharmaceutical products in the near term. However, in the future, we may consider manufacturing and marketing if we believe they are appropriate under the circumstances. We have no recent experience in developing pharmaceutical products or in manufacturing or marketing pharmaceutical products. We may not have the resources to develop or manufacture or market by ourselves any products based on genes identified by us. In the event we decide to establish a manufacturing facility, we will require substantial additional funds and will need to hire and train significant additional personnel and will need to comply with the extensive "good manufacturing practice" regulations applicable to such a facility. In addition, if the FDA regulated any products produced at our facility as biologics, we would need to file and obtain approval of an ELA for our facility. 32 HUMAN RESOURCES As of February 26, 2000, we had 174 full-time equivalent employees; 151 of these employees engaged in research and development activities and 23 of them conducted general and administrative functions. Thirty-six of our employees hold Ph.D. degrees and 49 more hold other advanced degrees. None of our employees is covered by a collective bargaining agreement, and we consider our relations with our employees to be good. FACILITIES Our executive offices and laboratories are located at 100 Beaver Street, Waltham, Massachusetts. We lease approximately 80,000 square feet of space and our lease expires on November 15, 2006 with options to extend for two consecutive five-year periods. During fiscal 1999, we incurred aggregate rental costs, excluding maintenance, taxes and utilities, for our facility of approximately $900,000. 33 MANAGEMENT DIRECTORS AND EXECUTIVE OFFICERS Our directors and executive officers and their respective ages and positions as of March 15, 2000 are as follows: NAME AGE POSITION - ---- -------- -------- Robert J.

AGENTS We may designate agents who agree to use their reasonable efforts to solicit purchases for the period of their appointment or to sell shares on a continuing basis. UNDERWRITERS If we use underwriters for a sale of shares, the underwriters will acquire the shares for their own account. The underwriters may resell the shares in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the shares will be subject to the conditions set forth in the applicable underwriting agreement. Any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time. DIRECT SALES We may also sell securities directly to one or more purchasers without using underwriters or agents. Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act and any discounts or commissions they receive from us and any profit on their resale of the shares may be treated as underwriting discounts and commissions under the Securities Act. The applicable prospectus supplement will identify any underwriters, dealers or agents and will describe their compensation. We may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Underwriters, dealers and agents may engage in transactions with or perform services for us or our subsidiaries in the ordinary course of their business. TRADING MARKETS AND LISTING OF SECURITIES The shares offered by this prospectus have been listed on the Nasdaq National Market. It is possible that one or more underwriters may make a market in a class or series of our shares, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the shares. STABILIZATION ACTIVITIES Any underwriter may engage in over allotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the shares in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the shares originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the shares to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. 36 VALIDITY OF COMMON STOCK Ropes & Gray, Boston, Massachusetts will pass upon the validity of the shares of common stock we are offering.

INDEMNIFICATION OF DIRECTORS AND OFFICERS The Company is organized under the laws of The Commonwealth of Massachusetts. The Massachusetts Business Corporation Law provides that indemnification of directors, officers, employees, and other agents of another organization, or who serve at its request is any capacity with respect to any employee benefit plan, may be provided by the corporation to whatever extent specified in its charter documents or votes adopted by its shareholders, except that no indemnification may be provided for any person with respect to any matter as to which the person shall have been adjudicated in any proceeding not to have acted in good faith in the reasonable belief that his action was in the best interest of the corporation. Under Massachusetts law, a corporation can purchase and maintain insurance on behalf of any person against any liability incurred as a director, officer, employee, agent, or person serving at the request of the corporation as a director, officer, employee, or other agent of another organization or with respect to any employee benefit plan, in his capacity as such, whether or not the corporation would have power to itself indemnify him against such liability. The Company's Restated Articles of Organization, as amended to date, provide that its directors shall not be liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that the exculpation from liabilities is not permitted under the Massachusetts Business Corporation Law as in effect at the time such liability is determined. The By-Laws provide that the Company shall indemnify its directors and officers to the full extent permitted by the laws of The Commonwealth of Massachusetts. In addition, the Company holds a Directors and Officer Liability and Corporate Indemnification Policy. II-1 ITEM 16.

ITEM 17. UNDERTAKINGS The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement 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. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described under "Item 15--Indemnification of Directors and Officers" above, 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 Securities 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 Securities Act and will be governed by the final adjudication of such issue. II-2 The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act, 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 purposes of determining any liability under the Securities Act, 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 undersigned Registrant hereby undertakes (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; and (2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment 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; and (3) to remove from registration by means of post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused this Amendment No. 5 to the registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Waltham, Commonwealth of Massachusetts, on this 12th day of May, 2000.
