BUSINESS OVERVIEW We are a biopharmaceutical company focused on the development of new biotherapeutics that address large medical markets, including cardiovascular disease and cancer. In November 2002 we initiated a Phase II clinical program for rNAPc2, a novel anticoagulant intended for the treatment of people affected by acute coronary syndromes, which include unstable angina and non-ST-segment elevation myocardial infarction, or UA/NSTEMI. Our cancer research programs are focused on the development of new biotherapies, including monoclonal antibodies and synthetic prodrugs, that target serine proteases associated with the growth and spread of cancerous tumors. Our core expertise is the design of drugs that inhibit, or otherwise modulate, enzymes known as serine proteases, which mediate a variety of normal biological and disease processes. Our scientists employ their understanding of the molecular and cellular mechanisms underlying blood clotting and tumor growth towards the ultimate goal of developing therapeutics administered by injection or taken in pill form that intervene at specific steps involved in disease processes. By targeting the molecular underpinnings of disease processes, we strive to develop new drugs that have improved potency, specificity and safety over currently available therapeutics. In support of this goal, we have integrated expertise from both the traditional pharmaceutical and biotechnology industries. These capabilities include gene expression and protein engineering, cellular, molecular and structural biology, medicinal chemistry and pharmacology. Through the use of medicinal chemistry, we have developed a new series of synthetic compounds that specifically deliver cytotoxic compounds to solid tumors following activation by serine proteases located on the cell surface. This technology, known as Protease Activated Cancer Therapy, or PACT, has advanced through testing in animal models of human prostate and breast cancer and we believe that this program will yield a clinical candidate within the next 12-18 months. We believe that coupling our PACT approach with our program to identify monoclonal antibodies directed against selected tumor-associated serine proteases will enable us to efficiently select multiple drug leads for targets throughout this important protease gene family. On February 25, 2003, we executed a definitive merger agreement under which Dendreon Corporation will acquire us, subject to various closing conditions including approval by the stockholders of each company. Under the terms of this agreement, each share of our common stock will be exchanged for a fixed ratio of 0.45 shares of Dendreon common stock in a tax-free reorganization. Upon successful closing of this transaction, our existing stockholders will own approximately 31.4% of the combined company. The transaction is anticipated to close in the second quarter of 2003, subject to approval by stockholders of both companies. -2- OTHER INFORMATION We originally incorporated in California in 1987 and reincorporated in Delaware in 1993.

LEAD IDENTIFICATION is the identification of compounds that modulate the activity of the target. rNAPc2 Recombinant nematode anticoagulant protein c2, or rNAPc2, is a novel and potent anticoagulant in clinical development for the prevention and treatment of acute coronary syndromes, which include unstable angina, or UA, and non-ST-segment elevation myocardial infarction, or NSTEMI. We originally discovered NAPc2, a natural form of the protein, in blood-feeding hookworms. rNAPc2 has been evaluated in over 500 patients and healthy volunteers in several Phase I studies, Phase II trials for the prevention of deep vein thrombosis, or DVT, and pulmonary embolism, as well as a Phase IIa safety trial in low-risk patients undergoing elective percutaneous coronary intervention, or PCI. Since many UA/NSTEMI patients receive medical intervention to open up clogged arteries, we conducted this study to determine the safety of rNAPc2 in such -3- circumstances. The data showed that rNAPc2 appears to be safe and well tolerated in this patient population. Based upon this safety data, in November 2002, we initiated a Phase II clinical program in UA/NSTEMI patients. Abnormal blood clot formation, or thrombosis, can reduce or completely block the flow of blood and oxygen supply to vital organs, which can lead to serious clinical conditions. The formation of blood clots in one or more coronary arteries of the heart may result in UA/NSTEMI, which oftentimes progresses to myocardial infarction, or heart attack, if left untreated. UA and NSTEMI are characterized by severe chest pain, even at rest, often the result of clogged coronary arteries. Blood clot formation is a normal repair mechanism that the body uses to recover from damage to blood vessels resulting from cuts, bruises or disease. The formation of a blood clot results from a complex series of biochemical events known as the blood coagulation cascade, which involves enzymes called serine proteases, cellular fragments called platelets and other proteins in blood. The coagulation cascade is most often triggered when there is damage or disruption to the lining of the blood vessel wall, or endothelium. This damage or disruption exposes the protein Tissue Factor, or TF, to the blood, allowing the serine protease Factor VIIa, which circulates freely in the blood, to bind to TF. The resulting Factor VIIa/Tissue Factor complex, or FVIIa/TF, is the initial trigger of the coagulation cascade and promotes the formation of another serine protease Factor Xa. Factor Xa causes the formation of the key serine protease thrombin. Thrombin then cleaves the protein fibrinogen into fibrin and activates platelets in the blood, which stick to each other and to the fibrin matrix, to form a blood clot in the damaged blood vessel. The resulting blood clot blocks blood flow and oxygen delivery to heart tissues, causing severe chest pain. The blood coagulation cascade is characterized by exponential amplification, starting with a small number of FVIIa/TF complexes and culminating in the formation of millions of thrombin molecules. Recombinant NAPc2 inhibits FVIIa/TF, thereby preventing the formation of thrombin. We believe that inhibiting the relatively few FVIIa/TF complexes early in the cascade may have significant safety and efficacy advantages over other anticoagulant strategies including indirect thrombin inhibitors such as unfractionated heparins and low molecular weight heparins, or LMWH, as well as direct thrombin inhibitors such as Angiomax, all of which target thrombin late in the cascade after amplification has occurred. Results from our Phase II open-label dose-ranging trial in 292 patients undergoing elective unilateral knee replacement surgery demonstrated that rNAPc2 appeared to reduce the risk of developing DVT and related complications by greater than 50% compared to the current standard therapy of unfractionated LMWH without compromising safety. Based on an end-of-Phase II meeting and subsequent communications with the Food and Drug Administration, or FDA, we concluded that an additional Phase II trial for DVT would be required to firmly establish a more commercially viable fixed dosing regimen. Although we continue to believe that rNAPc2 is a safe and effective therapy for the prevention of DVT, we made a decision in October 2001 to focus the clinical development of rNAPc2 on unstable coronary syndromes, which we believe is more commercially viable based on both the time to market and the rapidly-changing commercial environment in the DVT prophylaxis arena. Future clinical development of rNAPc2 in DVT will depend on securing an appropriate development partner. MARKET OPPORTUNITY. It is estimated that there are over 1.4 million hospitalizations for UA/NSTEMI each year in the United States alone. Historically, UA/NSTEMI has been treated with aspirin plus LMWH or unfractionated heparin. Recent guidelines have recommended that nearly all patients receive the antiplatelet agent Plavix in addition to the historical standard of care. We are developing rNAPc2 to be added to the current standard of care therapies. In moderate to high-risk patients with severe coronary artery disease, UA/NSTEMI may be treated with interventions such as PCI, which includes percutaneous transluminal coronary angioplasty, or PTCA, and stent placement. -4- Patients may also undergo coronary arterial bypass grafting or bypass surgery. In some cases, these patients may then receive antiplatelet drugs such as glycoprotein IIb/IIIa antagonists like ReoPro, Integrelin or Aggrastat. Traditional therapies are not completely effective; it is estimated that 8-15% of UA/NSTEMI patients will require additional PCI, suffer a heart attack or chest pain, or die within 30 days of hospital admission despite treatment with the current standard and use of an early interventional approach. By blocking the first step in the formation of a blood clot, we believe rNAPc2 may afford significant clinical benefit in high-risk patients with UA/NSTEMI when administered in combination with LMWH and aspirin, which work at later steps of the coagulation cascade. DEVELOPMENT STATUS. In order to establish the safety of rNAPc2 prior to initiating clinical trials in patients with unstable angina, we completed a double-blinded, placebo-controlled, dose-ranging Phase IIa study in patients undergoing elective PCI. In this trial, patients were randomized to receive either rNAPc2 or placebo with unfractionated heparin, aspirin and, in most cases, Plavix. The primary goal of the study was to assess safety as measured by femoral, or groin, compression time, which is a measure of the extent of bleeding at the surgical site used for placement of the coronary catheter. The Phase IIa results indicate that rNAPc2 appears to be safe and well tolerated in this patient population and that, in contrast to standard therapy with unfractioned heparin, aspirin and Plavix alone, rNAPc2 was shown to be more effective in suppressing the formation of thrombin in this elective PCI patient population. Based on the safety data obtained in this Phase IIa trial, in November 2002 we initiated a double-blinded, placebo-controlled Phase II clinical program of rNAPc2 in unstable angina patients. This trial, referred to as the Anticoagulation with NAPc2 To Help Eliminate MACE (ANTHEM/TIMI-32), is being coordinated with the help of the Thrombolysis in Myocardial Infarction, or TIMI, Group led by Dr. Eugene Braunwald of Brigham and Women's Hospital and Harvard Medical School. The TIMI Group has been performing clinical research in patients suffering from acute coronary syndromes since 1984. The ANTHEM/TIMI-32 Phase II program is composed of three parts. We will have an opportunity to decide whether to proceed with the trial following the conclusion of each part based on an evaluation of safety and efficacy. The first part, which is ongoing, is a double-blinded, randomized, placebo-controlled, dose-ranging trial which is designed to determine the safety of intravenously administered rNAPc2 in moderate to high-risk UA/NSTEMI patients undergoing PCI. This part is intended to sequentially enroll 125 patients at clinical centers in the United States randomized to either placebo or one of five rNAPc2 dose groups starting at 1.5 micrograms per kilogram of body weight increasing to 5.0 micrograms per kilogram. All patients will receive the low molecular weight heparin enoxaparin, or Lovenox, and aspirin, with the use of glycoprotein IIb/IIIa antagonists and Plavix determined by the attending physician. The primary objective of this portion of the trial is to determine a safe dose range for rNAPc2 in these patients using established and accepted criteria for bleeding. During the first part of this program, we will measure efficacy by the incidence of ischemic events as determined from seven day continuous electrocardiographic monitoring using portable Holter devices. The second and third parts of the ANTHEM/TIMI-32 program, which will follow the first part assuming favorable clinical results, are intended to focus on a broader patient population in both North America and Europe and will include moderate to high-risk patients that are not subject to an early interventional treatment strategy such as PCI. The primary efficacy endpoint for these subsequent phases of the clinical program are planned to be ischemic events measured using Holter monitors and clinical events including death, myocardial infarction and recurrent ischemia requiring re-hospitalization. This entire clinical program, which is expected to enroll 1,525 patients, is scheduled to take 18-24 months to complete. -5- PROTEASE MODULATION DISCOVERY AND DEVELOPMENT PROGRAMS FOR CANCER We are pursuing a new approach to the discovery and development of cancer therapeutics by targeting the serine protease gene family for drug discovery. Through our research on serine proteases involved in cardiovascular and viral disease, we have built a resident expertise in the understanding of serine protease biology and the design of synthetic small molecules that inhibit, or otherwise modulate, the activity of this protease family. In addition to protein drugs like rNAPc2 and small molecule inhibitors of the hepatitis C NS3A serine protease developed with Schering-Plough, we have developed core capabilities in the area of protease inhibition based on our fundamental understanding of serine protease structure and function. Serine proteases constitute the largest protease gene family in the human genome and have well-established roles in biological processes such as blood coagulation. The potential role serine proteases may play in the growth and progression of solid tumors is now emerging, and we believe that we are well positioned to exploit this knowledge for the development of novel anti-cancer agents. Proteases are proteins that act as molecular scissors to cleave other proteins to activate or inactivate them, and are responsible for regulating normal cellular function. The maintenance of normal health requires that the activity of proteases be tightly controlled. Excessive or deficient protease activity underlies many serious diseases in humans, including cardiovascular disease, cancer and many infectious diseases. The growth and progression of human tumors involve different proteases at multiple stages during these processes. Serine proteases are thought to be important for tumor cell growth directly and through the modulation of growth factors required for tumor growth. In addition, serine proteases have been shown to indirectly support tumor cell growth through their effects on the network of blood vessels that is essential for tumor survival, a process known as angiogenesis. We are focused on the development of drugs that suppress the growth of primary and secondary solid tumors by inhibiting known and novel key serine proteases involved in cancer processes. We employ an integrated approach to drug discovery that spans the discovery of serine proteases as cancer targets, the design and optimization of lead monoclonal antibody candidates against selected targets, and the subsequent validation of lead molecules in animal models of cancer. We use functional genomics to discover and validate serine protease targets, which includes initially cloning the full-length gene sequence and producing the functional domain or active portion of the protease as a recombinant enzyme. Using the recombinant enzymes, we have established automated assays to select monoclonal antibodies and small protein inhibitors in collaboration with external partners Dyax Corp. and Abgenix, Inc. In addition, we have determined the three-dimensional structure of several serine proteases complexed with lead small molecule inhibitors that were developed early in the program. We discontinued our small molecule development program in July 2002 as part of the realignment of our programs. We believe that this proprietary structural information will facilitate the optimization of drug candidates in collaboration with an appropriate partner using computer-aided drug design technologies that may be applicable to multiple targets across the serine protease gene family due to the similarities in their three-dimensional structure. In April 2002, we entered into an exclusive collaboration agreement with Abgenix to discover, develop and commercialize fully-human monoclonal antibodies against two selected antigens from our portfolio of membrane-bound serine proteases. Under the terms of the collaboration, Abgenix will use its human antibody technologies to generate and select antibodies against the Corvas targets. Both companies will have the right to co-develop and commercialize, or, if co-development is not elected, to solely develop and commercialize any antibody products discovered during the collaboration. Both companies will share equally in the product development costs and any profits from sales of products successfully commercialized from any co-development efforts. -6- In September 2001, we entered into a strategic alliance with Dyax to discover, develop and commercialize antibody, small protein and peptide inhibitors for two targets that we isolated and characterized. Under the terms of this agreement, both companies will jointly develop any inhibitory agents that may be identified and will share commercialization rights and profits, if any, from any marketed products. We believe that such joint development efforts may help maximize the potential of our serine protease approach to combat cancer by enabling a more rapid validation of these potential cancer targets and by providing additional sources of potential lead drug candidates to advance into clinical testing. We have also entered into a research and exclusive license agreement with Georgetown University related to Georgetown's intellectual property for matriptase, a novel serine protease cancer target implicated in several solid tumors including breast and prostate cancer. In the event that we develop and commercialize any products covered by Georgetown's intellectual property, we would be required to make milestone and royalty payments. We may enter into additional collaborative relationships to complement our resident expertise in protease modulation and help advance our cancer programs into the clinic. PROTEASE ACTIVATED CANCER THERAPY (PACT) PROGRAM. We have developed a strategy that exploits, rather than blocks, the activity of proteases on the surface of tumor cells. The goal of this prodrug approach is to deliver a potent cytotoxic, or cell-killing, drug directly to the tumor cells, thereby sparing healthy tissue from the toxic treatment. This program, called PACT, involves the design of synthetic molecules composed of a sequence of amino acids that are recognized by a targeted serine protease. This sequence of amino acids is chemically attached to a known cancer chemotherapeutic or cytotoxic drug such as doxorubicin, or dox, yielding a hybrid or conjugate molecule. We believe that our PACT approach will reduce damage to normal, non-tumor cells because the sequence of attached amino acids will prevent the cytotoxic drug from entering the normal cells where it could cause its lethal effects. In contrast, with the PACT approach a solid tumor should be more susceptible to the cytotoxic drug because the serine proteases in the tumor cells should free the cytotoxic drug in the vicinity of the tumor cell. Once free, the cytotoxic drug can enter into the tumor cell and kill it. We believe that this strategy of using the conjugate molecules will result in fewer side effects compared to cytotoxic drugs alone, many of which are in widespread use today. We have synthesized several different classes of conjugate molecules that have shown protease-specific liberation of the cytotoxic drug in cell culture. In addition, we have conducted extensive studies in mouse xenograft models of human prostate cancer. These models are commonly used to evaluate potential anti-tumor drugs prior to clinical development. In our animal studies, we have shown that our PACT approach enhanced uptake of the cytotoxic drug dox in several different human prostate tumors using our conjugate strategy in comparison to the use of dox alone. In addition, we have shown significant anti-tumor activity with several of our lead PACT compounds with fewer overall toxic side effects compared to dox alone. We expect to select a PACT clinical development candidate within the next 12-18 months, with clinical trials expected to begin in 2004. MEMBRANE-BOUND SERINE PROTEASE INHIBITOR PROGRAM. We also have a cancer program based on an emerging class of membrane-bound proteases which have been implicated in supporting the growth and progression of several types of solid tumors including prostate, breast, ovarian and colorectal cancers. Certain membrane-bound serine proteases have been shown to activate growth factors that are thought to promote the metastatic spread and establishment of tumor cells, as well as formation of new blood vessels, a process called angiogenesis, that nourish tumor cells and the growing tumor mass. Unlike most proteases, which are either secreted from or retained in the cell, membrane-bound serine proteases are located on the cell surface of the tumor cell. This confined location may offer a unique opportunity to target cancer treatments directly to diseased tumor cells, thereby avoiding damage to healthy cells and tissues, which is a serious problem associated with many current therapies including radiation and chemotherapy. -7- With our collaborators at the Max-Planck Institute for Biochemistry in Germany, we published the three-dimensional structure of matriptase, which represents the first structural characterization of this emerging class of cancer-associated transmembrane serine proteases. We have used matriptase as a target itself for the development of monoclonal antibodies. In addition we have also used a potent, specific small molecule inhibitor of matriptase developed in our now-discontinued small molecule program in experimental models of late-stage, human prostate cancer. The reported animal data demonstrates the anti-tumor effects of selective matriptase inhibition, which is an important step in validating this serine protease as a potential cancer target. In addition, we have cloned close to 30 genes encoding a growing number of members of this protease family from human cancer tissue or cell lines, as well as from human endothelial cells. Endothelial cells are key participants in supporting tumor growth through angiogenesis. UROKINASE PLASMINOGEN ACTIVATOR (u-PA) INHIBITOR PROGRAM. Urokinase is a serine protease that has been implicated in the growth and progression of certain solid tumors in the breast, ovary, colon and prostate. This serine protease facilitates angiogenesis and the survival of metastatic tumors in organs and tissues distant from the primary tumor. We have a portfolio of potent and selective inhibitors of urokinase plasminogen activator, or u-PA, developed prior to the discontinuance of our small molecule programs. We may collaborate with others on the development of these inhibitors as anti-tumor agents. In addition, we have also designed highly selective and potent monoclonal antibodies that have been shown to slow tumor growth in animal models. MARKET OPPORTUNITY. Cancer is the second leading cause of death in the United States, following heart disease. Breast and prostate cancer, our initial therapeutic focus areas, represent two of the largest cancer markets today, each accounting for over 180,000 new cases every year in the United States alone. It is estimated that over 1.1 million new cases of solid tumor cancers, including breast, prostate, ovarian and colorectal cancer, are diagnosed annually in the United States. Despite recent product introductions, we believe that physicians and patients are unsatisfied with currently available cancer treatments, presenting opportunities for companies like Corvas to develop more effective treatments. OTHER PROGRAMS HEPATITIS C LICENSE. We have collaborated with Schering-Plough to identify and optimize lead synthetic compounds for the inhibition of the key serine protease involved in the replication of the hepatitis C virus. Schering-Plough has exclusive rights to develop and commercialize products resulting from this collaboration, if any. We have no further responsibility for this program and would receive royalties on certain products that are commercialized by Schering-Plough under the license, if any. However, Schering-Plough has no obligation to pursue the commercialization of any products under this agreement, and we have no information on the status of ongoing efforts, if any. rNIF. As with rNAPc2, we discovered recombinant neutrophil inhibitory factor, or rNIF, from blood-feeding hookworms. In 1997, we licensed to Pfizer this anti-inflammatory agent, which was being developed for reperfusion injury associated with ischemic stroke. Based on results from a Phase IIb clinical trial, Pfizer terminated this collaboration in June 2002 and returned all rights to us. Based on the favorable safety profile that was obtained from several Phase I and two Phase II studies of more than 2,000 patients and volunteers conducted by Pfizer, we have been investigating alternative clinical indications for rNIF. We believe there may be alternative uses for rNIF in the treatment of acute inflammation that has been implicated in several cardiovascular indications including cardiopulmonary bypass surgery. We are planning to investigate these alternative opportunities for rNIF in relevant preclinical models prior to making any decisions to move forward with the development of this compound. In addition to its safety profile, we have a well-defined, proprietary manufacturing process that would be used to develop rNIF for alternative indications. -8- OUR STRATEGY In the event that we continue as a stand-alone company, our objective is to build a profitable, fully integrated biopharmaceutical company focused on the development of new biotherapeutics that address large markets, including cardiovascular disease and cancer. Our strategy involves the generation of a revenue stream by completing the development and commercialization of our rNAPc2 cardiovascular product candidate currently in clinical trials, ultimately with the support of strategic alliances. Our internal growth will focus on the advancement of our cancer pipeline through our own internal drug discovery and development efforts, strategic partnerships and opportunistic acquisitions of complementary technologies, products or companies that are consistent with our growth objectives. The key elements of our strategy to accomplish this objective are to: o ADVANCE THE DEVELOPMENT OF rNAPc2. We intend to continue the development of rNAPc2 for the treatment of acute coronary syndromes, which include UA/NSTEMI. In order to maximize the value of rNAPc2 and reduce our cash requirements for clinical trials, we may enter into one or more appropriate strategic partnerships for the commercialization of this drug following either the completion of any of the parts of the ongoing ANTHEM/TIMI-32 trial or following completion of the entire trial. o DISCOVER AND DEVELOP NOVEL THERAPEUTICS FOR SOLID TUMOR CANCER. We plan to use our expertise in modulating protease activity to discover and develop a new generation of drugs for treating solid tumors focused on exploiting known and novel serine protease targets. We expect our initial product candidate to come from our PACT program. We will also focus on developing product candidates based on monoclonal antibodies through external collaborations such as Dyax and Abgenix. We selected this therapeutic area due to its large market size and unmet medical need, the potential for expedited review by the FDA, and the smaller and, oftentimes, less expensive clinical trials required for the commercialization of cancer drugs. We also believe we can effectively build an internal sales force to commercialize any cancer products we may develop due to the relatively small number of treating physicians in oncology. o FORM CORPORATE COLLABORATIONS TO SUPPORT THE DEVELOPMENT AND COMMERCIALIZATION OF OUR PRODUCTS. We intend to continue to pursue collaborations to expand our product development capabilities. We believe that collaborations will be particularly useful for the development of products with a large target market where clinical development and commercialization efforts will require a very substantial investment of financial and human resources. We believe that by entering into collaborations with respect to selected programs, we also create the potential for multiple sources of revenue and diversify our scientific and financial risk. o ACQUIRE COMPLEMENTARY PRODUCTS, TECHNOLOGIES OR COMPANIES, OR COMBINE WITH ANOTHER COMPANY. Our strategy of seeking to expand on our internal development efforts by in-licensing or acquiring potential products or technologies developed by third parties or acquiring complementary businesses led us to execute the definitive merger agreement with Dendreon. If this merger is not completed for any reason, we would re-access this strategy. PATENTS AND PROPRIETARY RIGHTS We believe that patents, trademarks, copyrights and other proprietary rights are important to our business. We rely on trade secrets, know-how, continuing technological innovations and licensing opportunities to develop and maintain our competitive position. Our success will depend in part on our ability to obtain additional patents, maintain trade secrets and operate without infringing the proprietary rights of others, both in the United States and other -9- countries. We periodically file patent applications to protect the technology, inventions and improvements that may be important to the development of our business. Our strategy is to file applications as appropriate for patents covering both our products and processes. As of February 28, 2003, we have 68 issued U.S. patents and have received Notices of Allowance for three U.S. patent applications that have not yet issued as patents. Our issued patents and patent applications include claims directed to potential pharmaceutical compounds, such as rNAPc2, rNIF and protease inhibitors, to methods of making the compounds and for treating specific diseases using the compound. We have filed approximately 46 additional patent applications that currently are pending in the U.S. Patent and Trademark Office. Most of these patent applications relate to our cancer programs and are directed to novel protease targets, novel pharmaceutical compounds which modulate these protease targets, methods of identifying such pharmaceutical compounds and methods of treating specific diseases by modulating these protease targets with novel or known pharmaceutical compounds. We have filed foreign counterparts to some of our issued patents and patent applications in many countries. Generally, it is our policy to file foreign counterparts in countries with significant pharmaceutical markets. Some of these foreign counterparts have issued as patents or have been allowed. We continue to actively seek patent protection for these related technologies in the United States and foreign countries. Under the terms of our collaborations, third parties may have rights to patents owned by us as specified under applicable agreements. It is possible that a patent will not issue from any of our owned or licensed patent applications, and the breadth or scope of protection allowed under any issued patents may not provide adequate protection to protect our products. In addition, any patents that we own may be challenged and invalidated by a third party or circumvented, and any rights granted to us may not provide adequate protection. We also rely on trade secrets and contractual arrangements to protect our trade secrets. Much of the know-how important to our technology and many of its processes are dependent upon the knowledge, experience and skills of our key scientific and technical personnel and are not the subject of pending patent applications or issued patents. To protect our rights to know-how and technology, we require all of our employees, consultants, advisors and collaborators to enter into confidentiality agreements with us that prohibit the unauthorized use of, and restrict the disclosure of, confidential information, and require disclosure and assignment to us during the term of their employment of their ideas, developments, discoveries and inventions related to the services that they perform for us. In the past, some of our research has been funded in part by grants from the U.S. government. As a result of this funding, the government has rights to any technology, including inventions, developed with the funding. These rights include the grant of a non-exclusive, paid-up, worldwide license to related inventions for any governmental purpose. In addition, the government has the right to require us to grant an exclusive license to any of these inventions to a third party if the government determines that: o adequate steps have not been taken to commercialize those inventions; o the license is necessary to meet public health or safety needs; and o the license is necessary to meet requirements for public use under federal regulations. Federal law requires any licensor of an invention that was partially funded by federal grants to obtain a covenant from its exclusive licensee to manufacture any products using the invention in the United States. In addition, our licenses may also relate to technology developed with federal funding and, therefore, may also be subject to rights held by the government. -10- GOVERNMENT REGULATION Research, preclinical development, clinical trials, manufacturing and marketing activities are subject to regulation for safety, efficacy and quality by numerous governmental authorities in the United States and other countries. In the United States, drugs are subject to rigorous FDA regulation. The Federal Food, Drug and Cosmetic Act and other federal and state statutes and regulations govern, among other things, the testing, manufacture, safety, efficacy, labeling, storage, record keeping, approval, advertising and promotion of our products. Product development and approval within this regulatory framework take a number of years and involve substantial resources. The steps required before a pharmaceutical agent may be marketed in the United States include: o preclinical laboratory tests, animal pharmacology and toxicology studies, and formulation studies; o the submission of an investigational new drug application, or an IND, to the FDA for human clinical testing, which may be reviewed by the FDA before human clinical trials may commence; o the carrying out of adequate and well-controlled human clinical trials must be conducted by us or our collaborators to establish the safety and efficacy of the drug candidate; o the submission of a new drug application to the FDA; and o FDA approval of the new drug application to allow us to conduct any commercial sale or shipment of the drug. In addition to obtaining FDA approval for each product, each domestic drug manufacturing establishment must be registered with the FDA. Domestic drug manufacturing establishments are subject to regular inspections by the FDA and must comply with FDA regulations. To supply products for use in the United States, foreign manufacturing establishments must also comply with FDA regulations and are subject to periodic inspection by the FDA, or by corresponding regulatory agencies in their home countries under reciprocal agreements with the FDA. Preclinical studies include the laboratory evaluation of in vitro pharmacology, product chemistry and formulation, as well as animal studies to assess the potential safety and efficacy of a product. Compounds must be formulated according to the FDA's regulations on Good Manufacturing Practices and preclinical safety tests must be conducted by laboratories that comply with FDA regulations regarding Good Laboratory Practices. The results of the preclinical tests are submitted to the FDA as part of an IND and are reviewed by the FDA before human clinical trials may begin. The IND must also contain protocols for any clinical trials that will be carried out. If the FDA does not object to an IND, the IND becomes effective 30 days following its receipt by the FDA. At any time during this 30 day waiting period or at any time thereafter, the FDA may halt proposed or ongoing clinical trials until the agency authorizes trials under specified terms. Such a halt, called a clinical hold, continues in effect unless and until the FDA's concerns are adequately addressed. In some cases, clinical holds are never lifted. Imposition by the FDA of a clinical hold can delay or preclude further product development. The IND process may be extremely costly and may substantially delay product development. -11- Clinical trials must be sponsored and conducted in accordance with good clinical practice under protocols and methodologies that: o ensure receipt of signed consents from participants that inform them of risks; o detail the protocol and objectives of the study; o detail the parameters to be used to monitor safety; and o detail the efficacy criteria to be evaluated. Furthermore, each clinical study must be conducted under the supervision of a principal investigator operating under the auspices of an Institutional Review Board, or IRB, at the institution where the study is conducted. The IRB will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution. Sponsors, investigators and IRB members are obligated to avoid conflicts of interests and ensure compliance with all legal requirements. Clinical trials are typically conducted in three sequential phases. In Phase I, the initial introduction of the drug into a small number of patients or healthy volunteers is undertaken. The drug is evaluated for safety by assessing the adverse effects, dosage tolerance, metabolism, distribution, excretion and clinical pharmacology. The Phase I trial must provide pharmacological data that is sufficient to devise the Phase II trials. Phase II trials involve studies in a larger, yet limited, patient population in order to: o obtain initial indications of the efficacy of the drug for specific, targeted indications; o determine dosage tolerance and optimal dosage; and o identify possible adverse affects and safety risks. When a compound is determined preliminarily to be effective and to have an acceptable safety profile in Phase Il evaluation, Phase III trials can be undertaken to evaluate safety and efficacy endpoints further in expanded patient populations at geographically diverse clinical trial sites. Positive results in Phase II trials are no guarantee of positive results in Phase III. The results of the pharmaceutical development, preclinical studies and clinical trials are submitted to the FDA in the form of a new drug application, which must be complete, accurate and in compliance with FDA regulations. The approval of a new drug application permits commercial-scale manufacturing, marketing, distribution, exporting from the United States and sale of the drug in the United States. The testing and approval process typically requires substantial time, effort and expense. The FDA may deny a new drug application filed by us or our collaborators if the applicable scientific and regulatory criteria are not satisfied and thus, we may not be able to manufacture and sell the product in the United States. Moreover, the FDA may require additional testing or information, or may require post-approval testing, surveillance and reporting to monitor the products. Notwithstanding any of the foregoing, the FDA may ultimately decide that a new drug application filed by us or our collaborators does not meet the applicable agency standards and, even if approval is granted, it can be limited or revoked if evidence subsequently emerges casting doubt on the safety or efficacy of a product or if the manufacturing facility, processes or controls do not comply with regulatory standards. Finally, an approval may include limitations on the uses, labeling, dosage forms, distribution and packaging of the product. -12- Among the conditions for new drug approval is the requirement that the prospective manufacturer's quality control, record keeping, notifications and reporting, and manufacturing systems conform to the FDA's regulations on current Good Manufacturing Practices. In complying with the standards contained in these regulations, manufacturers must continue to expend time, money, resources and effort in order to ensure compliance. Outside the United States, our ability to market a product is contingent upon receiving a marketing authorization from the appropriate regulatory authority. This foreign regulatory approval process includes many of the same steps associated with FDA approval described above. In addition to regulations enforced by the FDA, we are subject to regulation under the Occupational Safety and Health Act, the Environmental Protection Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act and other present and future federal, state or local regulations. Our research and development activities involve the controlled use of hazardous materials, chemicals and various radioactive compounds. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of an accident, we could be liable for any damages that may result. COMPETITION Due to the high incidence of cardiovascular disease and cancer, most, if not all, of the major pharmaceutical companies have significant research and product development programs in these areas. We expect to encounter significant competition both in the United States and in foreign markets for each of the drugs we seek to develop. Several existing products have well-established market positions and there are a number of new products in advanced clinical development. If commercialized, the success of rNAPc2 will depend upon cardiologists accepting the drug as part of the current standard of care for the acute treatment of UA/NSTEMI. Many biotechnology and pharmaceutical companies are focused on the development of drugs to treat cancer, and we expect that any products we develop may compete against today's standard treatments and any potential new drugs that are currently under development. Our competitors include fully-integrated pharmaceutical and biotechnology companies both in the United States and in foreign markets which have expertise in research and development, manufacturing processes, testing, obtaining regulatory clearances and marketing, and may have significantly greater financial and other resources than we do. Smaller companies may also prove to be significant competitors. Academic institutions, U.S. and foreign government agencies and other public and private research organizations conduct research relating to diseases we target, and may develop products for the treatment of these diseases that may compete directly with any we develop. Our competitors may also compete with us for collaborations. In addition, these companies and institutions compete with us in recruiting and retaining highly qualified scientific personnel. Our competition will be determined, in part, by the potential indications that are ultimately cleared for marketing by regulatory authorities, by the timing of any clearances and market introductions and by whether any currently available drugs, or drugs under development by others, are effective in the same indications. Accordingly, the relative speed with which we can develop product candidates, complete the clinical trials, receive regulatory approval and supply commercial quantities of the products to the market is expected to be an important competitive factor. We expect that competition among products approved for sale will be based, among other things, on product efficacy, safety, reliability, availability, price and patent position. Our competitive position also depends on our ability to attract and retain qualified personnel, obtain protection for our proprietary products and processes, and secure sufficient capital resources. -13- EMPLOYEES As of February 28, 2003, we employed 55 individuals on a full-time basis, of which 14 hold Ph.D. degrees. A significant number of our management and professional employees have had prior experience with pharmaceutical, biotechnology or medical product companies. None of our employees is covered by a collective bargaining agreement. All of our employees are covered by confidentiality agreements, and three of our officers have employment contracts. We believe that our relationship with employees is good. AVAILABLE INFORMATION Our website address is www.corvas.com. We make available free of charge through our website our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and all amendments to those reports as soon as reasonably practicable after such material is electronically filed with or furnished to the Securities and Exchange Commission. RISK FACTORS WE MAY NOT BE SUCCESSFUL IN COMPLETING OUR PROPOSED ACQUISITION BY DENDREON CORPORATION. Although we executed a definitive merger agreement with Dendreon, it is subject to various closing conditions including approval by the stockholders of both companies and it is possible that the merger may not be completed in the stated timeframe or at all. Two of our stockholders have publicly stated that they are opposed to the merger and intend to vote against it. If the proposed merger is not completed or is delayed, our business may suffer for a number of reasons including, but not limited to, other opportunities foregone while the transaction was pending, additional costs incurred in support of the proposed merger, loss of employees due to uncertainty surrounding the acquisition and a further reduction in our cash balances. Even if the proposed merger is completed, we may fail to realize the anticipated benefits of the merger. WE HAVE A HISTORY OF OPERATING LOSSES AND WE MAY NEVER BECOME PROFITABLE. We have experienced significant operating losses since our inception in 1987. At December 31, 2002, we had an accumulated deficit of approximately $146.2 million. We have not earned any revenues from commercial sales of any therapeutic products. We have funded our operations principally from sales of our equity and debt securities, payments received from collaborators and interest income. Currently, we do not have any committed sources of external funding. We will continue to incur substantial additional operating losses for at least the next several years as we pursue our clinical trials and research and development efforts. To become profitable as a stand-alone company, we, either alone or with our collaborators, would have to successfully identify, develop, manufacture and market new product candidates. We do not expect to generate revenues from product sales or royalties from commercial sales of our products for at least a number of years, and it is possible that we will never have product sales revenue or receive significant royalties from sales of any of our licensed products. -14- WE HAVE NEVER HAD A PRODUCT CANDIDATE ADVANCE BEYOND PHASE II CLINICAL TRIALS AND WE DO NOT HAVE, AND MAY NEVER DEVELOP, ANY COMMERCIAL DRUGS OR OTHER PRODUCTS THAT GENERATE REVENUES. We are at an early stage of development as a biopharmaceutical company, and we do not have any commercial products. In November 2002, we initiated the ANTHEM/TIMI-32 trial for our only clinical stage product candidate, rNAPc2. rNAPc2 will require significant additional development, clinical trials, regulatory clearances and additional investment before it can be commercialized. Our product development efforts may not lead to commercial drugs, either because our product candidates fail to be safe and effective in clinical trials or because we have inadequate financial or other resources to pursue the program through the clinical trial process. We do not expect to be able to market rNAPc2 or any future product candidates for a number of years, if at all. If we remain a stand-alone company and we are unable to develop any commercial drugs, or if such development is delayed, we may be required to we raise additional capital through financings, scale back or discontinue some part of our operations, or cease our operations entirely. WE ARE DEPENDENT ON THE SUCCESSFUL OUTCOME OF THE CLINICAL TRIALS FOR OUR rNAPc2 PRODUCT CANDIDATE. Because we currently have only one product in clinical development, our business prospects depend in large part on our ability, alone or with collaborators, to successfully commercialize rNAPc2. Many factors will affect our current and future clinical trials for rNAPc2 including patient enrollment, which is affected by the size of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the trial, competing clinical trials and new drug approvals. Delays in patient enrollment in our current or any future trials may result in increased costs, program delays, or both, which could slow down our product development and approval process. If clinical trials for rNAPc2 are not completed or conducted as planned, due to any reason including, but not limited to, rNAPc2 not being safe or effective, the commercialization of rNAPc2 would likely be delayed or prevented, our business would likely be materially harmed and, if we remain a stand-alone company, our stock price would likely decline. In addition, if we do not receive required regulatory approvals, we may never commercialize rNAPc2 and therefore may never be profitable. Finally, if rNAPc2 were to fail in the ANTHEM/TIMI-32 trial prior to the closing of the proposed merger with Dendreon, then Dendreon would have the right to terminate the merger agreement due to the occurrence of a material adverse event. OUR rNAPc2 CLINICAL TRIALS MAY TAKE LONGER TO COMPLETE THAN WE PROJECT. Many factors including, but not limited to, difficulty recruiting and enrolling patients who meet our trial eligibility criteria, regulatory requirements, and problems at the clinical sites may cause delays that would extend the duration of any of the three parts of the ANTHEM/TIMI-32 trial, or prevent the completion of any part of this trial. Further, we are relying primarily upon third parties to conduct, supervise and monitor our rNAPc2 clinical trials under the oversight of our clinical group and, therefore, have less control over the timing and other aspects of this program than if we conducted the trials on our own. If such delays are significant, we may never commercialize rNAPc2 and therefore may never be profitable. OUR PRECLINICAL AND CLINICAL TESTING RESULTS ARE UNCERTAIN. IF TRIAL RESULTS ARE NEGATIVE, WE MAY BE FORCED TO STOP DEVELOPING PRODUCT CANDIDATES IMPORTANT TO OUR FUTURE. The results of preclinical studies and initial clinical trials of our product candidates will not necessarily predict the results obtained from later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy endpoints despite having progressed through initial clinical testing. In addition, the data collected from clinical trials of our product candidates may not be sufficient to support FDA or other regulatory approval. Although we have completed a Phase IIa clinical trial of rNAPc2 in patients undergoing elective coronary angioplasty to -15- establish safety prior to conducting additional clinical trials in patients with UA/NSTEMI, results from our ANTHEM/TIMI-32 trial may not support the continued development of rNAPc2. rNAPc2, or any future product candidates we may develop, may not be safe for human use. Administering any of our product candidates to humans may produce undesirable side effects. These side effects could interrupt, delay or cause us or the FDA to halt clinical trials of our product candidates and could result in the FDA or other regulatory authorities denying approval of our product candidates for any or all targeted indications. Along with the FDA or other regulatory authorities, we, or our collaborators, may suspend or terminate clinical trials at any time. THE FDA HAS NEVER APPROVED ANY CORVAS PRODUCT CANDIDATE AND WE MAY NEVER BE PERMITTED TO COMMERCIALIZE ANY PRODUCT WE DEVELOP. We have never had a product candidate advance beyond the early stages of development and none have received the regulatory clearance required from the FDA or any other regulatory body to be commercially marketed and sold. While our goal is to commence commercial sales of rNAPc2 and any other product candidate we may develop, we may not achieve this goal for any product candidate in the expected timeframe, or at all. The regulatory clearance process typically takes many years and is extremely expensive, and regulatory clearance is never guaranteed. If we fail to obtain regulatory clearance for our current or future product candidates, we will be unable to market and sell any products and therefore may never be profitable. As part of the regulatory clearance process, for each of our product candidates we must conduct, at our own expense or a collaborator's expense, preclinical research and clinical trials to demonstrate safety and efficacy. In addition, it is difficult to predict if the FDA will agree with the design of our clinical trials. Even though earlier clinical trial results for a particular compound and a specific indication may indicate that the compound appears to be safe and effective, the FDA may suggest or even require that additional clinical trials be completed before advancing to later-stage trials. The number of preclinical studies and clinical trials that will be required varies depending on many factors including the product, disease or condition that the product is in development for, and regulations applicable to a particular product. The FDA can delay, limit or not grant approval for many reasons, including: o a product candidate may not demonstrate sufficient safety or efficacy; o FDA officials may interpret data from preclinical testing and clinical trials in different ways than we interpret it, or require data that is different from what was obtained in our clinical trials; o the FDA may not approve our manufacturing processes or facilities, or the processes or facilities of our collaborators; and o the FDA may change its approval policies or adopt new regulations. The FDA also may approve a product candidate for fewer indications than requested or may condition approval on the performance of post-marketing studies for a product candidate. Even if we receive FDA and other regulatory approvals, our product candidates may later exhibit adverse effects that limit or prevent their widespread use or that force us to withdraw those product candidates from the market. In addition, any marketed product and its manufacturer continue to be subject to strict regulations after approval. Any unforeseen problems with an approved product or any violation of regulations could result in restrictions on the product, including its withdrawal from the market. -16- The process of obtaining approvals in foreign countries is subject to delay and failure for many of the same reasons. Any delay in, or failure to receive approval for, any of our products could materially harm our business, financial condition and results of operations. IF WE FAIL TO ENTER INTO FUNDED COLLABORATION AGREEMENTS FOR OUR DRUG PROGRAMS, WE MAY BE UNABLE TO COMPLETE THE DEVELOPMENT AND COMMERCIALIZATION OF rNAPc2 AND ANY OTHER PRODUCT CANDIDATES WE MAY DEVELOP, OR TO CONTINUE OUR RESEARCH AND DEVELOPMENT PROGRAMS. Our operations have consumed substantial amounts of cash since inception. Our sources of revenue have been primarily limited to research funding, license fees and milestone payments from corporate collaborators. In 2002, we had a net loss of approximately $21.2 million and we anticipate that our 2003 net loss will be larger. As a stand-alone company, we expect that we will continue to spend substantial amounts on research and development, including the costs of our ongoing ANTHEM/TIMI-32 trial as well as clinical trials for future product candidates, if any. Our future burn rate and capital needs will depend on many factors, including, but not limited to, the outcome of the first part of the ongoing ANTHEM/TIMI-32 trial and those factors outlined in "Liquidity and Capital Resources." We do not have committed external sources of funding. If we are unable to enter into future collaboration agreements, including co-development and marketing agreements, or raise additional capital when required or on acceptable terms, we may have to significantly delay, scale back or discontinue one or more of our drug discovery programs, clinical trials or other aspects of our operations. We also could be required to: o seek corporate collaborators for programs at an earlier stage than would be desirable to maximize the rights that we retain to future product candidates; and/or o relinquish or license rights to technologies, product candidates or products that we would otherwise seek to develop or commercialize ourselves on terms that are less favorable to us than might otherwise be available. IF WE DO NOT FIND COLLABORATORS FOR rNAPc2 AND FOR ANY OTHER PRODUCT CANDIDATES WE MAY DEVELOP, WE MAY HAVE TO REDUCE OR DELAY OUR RATE OF PRODUCT DEVELOPMENT AND/OR INCREASE OUR EXPENDITURES. Our strategy for developing, manufacturing and commercializing our products includes entering into various relationships with pharmaceutical and/or biotechnology companies to advance our programs and reduce our expenditures on each program. We may not be able to negotiate additional collaborations on acceptable terms or at all. If we are not able to establish additional collaborative arrangements, we may have to reduce or delay further development of rNAPc2 or some of our cancer programs in the future and/or increase our expenditures and undertake further development activities at our own expense. Beyond completion of the ongoing ANTHEM/TIMI-32 trial, future clinical development of rNAPc2 may depend on securing an appropriate development partner. If we elect to increase our expenditures to fund our development programs, we will need to obtain additional capital, which may not be available on acceptable terms or at all. We may have to rely on our collaborators for all aspects of partnered programs, including the conduct of research and development that the collaborator chooses to conduct, clinical trials and the regulatory approval process. We may have no control over the amount and timing of resources that our collaborators dedicate to the development of our licensed product candidates, if any. Our ability to generate royalties from our collaborators depends on their abilities to establish the safety and efficacy of our product candidates, obtain regulatory approvals and achieve market acceptance of our products. -17- Collaborative agreements generally pose the following risks: o collaborators may not pursue further development and commercialization of compounds resulting from collaborations or may elect not to renew research and development programs; o collaborators may delay clinical trials, underfund a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials, require a new formulation or encounter other manufacturing difficulties of a product candidate for clinical testing; o collaborators could independently develop, or develop with third parties, products that could compete with our future products; o the terms of our agreements with current or future collaborators may not be favorable to us in the future; o a collaborator with marketing and distribution rights to one or more products may not commit enough resources to the marketing and distribution of our products, limiting our potential revenues from the commercialization of a product; o disputes may arise delaying or terminating the research, development or commercialization of our product candidates, or result in significant litigation or arbitration; o collaborations through which our collaborator is funding all or a portion of the research and development may be terminated and we will experience increased capital requirements if we elect to pursue further development of the product candidate; and o collaborators may not have the financial or other resources to fund the research, development or commercialization of our product candidates, and we will experience increased capital requirements if we elect to pursue further development of these candidates. In addition, there have been a significant number of business consolidations among and between large pharmaceutical and biopharmaceutical companies that have resulted in a reduced number of potential future collaborators. If business combinations involving our existing or potential collaborators were to occur, the effect could be to diminish, terminate or cause delays in one or more of our product development programs. OUR COMPETITORS MAY DEVELOP AND MARKET DRUGS THAT ARE LESS EXPENSIVE, MORE EFFECTIVE, OR SAFER, OR REACH THE MARKET SOONER WHICH MAY DIMINISH OR ELIMINATE THE COMMERCIAL SUCCESS OF ANY PRODUCTS WE MAY COMMERCIALIZE. The biopharmaceutical market is highly competitive. We expect that competition from other biopharmaceutical companies, pharmaceutical companies, universities and public and private research institutions will increase. Almost all of the larger biopharmaceutical companies have developed, or are attempting to develop, products that will compete with products we may develop, including some that are in advanced stage clinical trials. In particular, many other companies and institutions have active programs for cardiovascular disease and cancer against which ours may compete. It is possible that our competitors will develop and market products that are less expensive, more effective or safer than our future products, if any, or that will render our products obsolete. It is also possible that our competitors will commercialize competing products before any of our products are approved and marketed. Many of our competitors -18- have substantially greater financial, technical, research and other resources than we do. We may not have the financial resources, technical expertise or marketing, distribution or support capabilities to compete successfully. MARKET ACCEPTANCE OF rNAPc2 AND FUTURE PRODUCT CANDIDATES, IF ANY, IS UNCERTAIN. If approved, we intend for rNAPc2 to be used in combination with the current treatment regimen for UA/NSTEMI. However, physicians may not ultimately use rNAPc2. Physicians will only prescribe rNAPc2 or any of our future products if they determine, based on experience, clinical data, side effect profiles and other factors, that they are beneficial in combination with other products or preferable to other products then in use. Recommendations and endorsements by influential physicians will be essential for market acceptance of rNAPc2 or future products, if any, and we may not be able to obtain these recommendations and endorsements. In addition, many other factors influence the adoption of new drugs, including marketing and distribution restrictions, adverse publicity, product pricing and reimbursement by third-party payers. Even if rNAPc2 and our future product candidates, if any, achieve market acceptance, the market may not be sufficiently large to result in significant revenues. If any of our products do not achieve adequate sales, we may never be profitable and our business and financial condition would be adversely affected. FAILURE TO RETAIN KEY SCIENTIFIC PERSONNEL COULD DECREASE OUR ABILITY TO DEVELOP OUR PRODUCT CANDIDATES AND, IF WE REMAIN A STAND-ALONE COMPANY, TO CONTINUE TO OBTAIN NEW COLLABORATIONS OR OTHER SOURCES OF FUNDING. We depend, to a significant extent, on the efforts of our key employees. The loss of these individuals may delay or prevent us from achieving our business objective of commercializing our product candidates. Our future success will also depend in large part on our continued ability to attract and retain other highly qualified scientific, technical and management personnel, as well as personnel with expertise in clinical testing and governmental regulation. We face intense competition for personnel from other companies, universities, public and private research institutions, government entities and other organizations. If we are unsuccessful in our recruitment and retention efforts, our business operations will be harmed. BECAUSE WE HAVE LIMITED MANUFACTURING EXPERIENCE AND WE RELY ON THIRD-PARTY MANUFACTURERS, WE ARE UNABLE TO CONTROL THE AVAILABILITY OF, AND MANUFACTURING COSTS FOR, OUR PRODUCT CANDIDATES. In order to be successful, our product candidates must be capable of being manufactured in sufficient quantities, in compliance with regulatory requirements, and at an acceptable cost. We have only limited experience in pilot scale manufacturing. For larger-scale production, which is required for clinical testing, we expect to continue to rely on third parties to manufacture our product candidates. There are only a limited number of contract manufacturers capable of manufacturing rNAPc2. If we cannot continue to contract for large-scale manufacturing capabilities on acceptable terms, or if we encounter delays or difficulties with manufacturers, we may not be able to conduct clinical trials as planned. This would delay or cause us to halt submission of our product candidates for regulatory clearance, and may prevent us from selling our products and achieving profitability. Also, our third-party manufacturers may be unable to manufacture any product candidate we develop in commercial quantities on a cost-effective basis. We may need to expand our existing relationships or establish new relationships with third-party manufacturers for rNAPc2 and for future product candidates, if any. We may be unable to establish or maintain relationships with third-party manufacturers on acceptable terms, or at all. Our dependence on third parties may reduce our profit margins and delay or limit our ability to develop and commercialize our products on a timely and competitive basis. Furthermore, third-party manufacturers may encounter manufacturing or quality control problems in connection with the manufacture of our product candidates -19- and may be unable to obtain or maintain the necessary governmental licenses and approvals to manufacture our product candidates. Any such failure could delay or preclude receiving regulatory approvals to sell our product candidates. IF WE ARE UNABLE TO PROTECT OUR PROPRIETARY TECHNOLOGY, WE MAY NOT BE ABLE TO COMPETE AS EFFECTIVELY. Our success depends in part on our ability to obtain and enforce patent protection for our products, both in the United States and other countries, and operate without infringing the proprietary rights of third parties. The scope and extent of patent protection for our product candidates is uncertain and frequently involves complex legal and factual questions. We cannot predict the breadth of claims that will be allowed and issued in patents related to biotechnology or pharmaceutical applications. Once patents have issued, we cannot predict how the claims will be construed or enforced. In addition, statutory differences between countries may limit the protection we can obtain on some of our inventions outside of the United States. For example, methods of treating humans are not patentable in many countries outside of the United States. We rely on patent and other intellectual property protection to prevent our competitors from developing, manufacturing and marketing products based on our technology. Our patents may not be enforceable and they may not afford us protection against competitors, especially since there is a lengthy lead time between when a patent application is filed and when it is actually issued. Because of this, we may infringe on intellectual property rights of others without being aware of the infringement. If a patent holder believes that one of our product candidates infringes on their patent, they may sue us even if we have applied, or received patent protection, for our technology. If another party claims we are infringing their technology, we could face a number of issues, including the following: o defending a lawsuit, which is very expensive and time consuming; o paying a large sum for damages if we are found to be infringing; o being prohibited from selling or licensing our products or product candidates until we obtain a license from the patent holder, who may refuse to grant us a license or only agree to do so on unfavorable terms. Even if we are granted a license, we may have to pay substantial royalties or grant cross-licenses to our patents; and o redesigning our drug so it does not infringe on the patent holder's technology. This may not be possible and, even if possible, it would require substantial additional capital, FDA approval, and would delay commercialization. The coverage claimed in a patent application can be significantly narrowed before a patent is issued, either in the United States or abroad. We do not know whether any of our pending or future patent applications will result in the issuance of patents. To the extent patents have been issued or will be issued, we do not know whether these patents will be subjected to further proceedings limiting their scope, will provide significant proprietary protection or competitive advantage, or will be circumvented or invalidated. Furthermore, patents already issued to us, or patents that may issue on our pending applications, may become subject to dispute, including interference proceedings in the United States to determine priority of invention or opposition proceedings in foreign countries contesting the validity of issued patents. We also rely on trade secrets, proprietary know-how and continuing inventions to develop and maintain our competitive position. While we believe that we have protected our trade secrets, some of our current or former employees, consultants or scientific advisors, or current or prospective corporate collaborators, may unintentionally or willfully disclose our confidential information to competitors or use our proprietary technology for their own benefit. Furthermore, enforcing a claim alleging the infringement of our trade secrets would be expensive and difficult to prove, making the outcome -20- uncertain. Our competitors may also independently develop equivalent knowledge, methods and know-how or gain access to our proprietary information through some other means. Because we collaborate with third parties on some of our technology, there is also the risk that disputes may arise as to the rights to technology or drugs developed in collaboration with other parties. IF WE BECOME SUBJECT TO PRODUCT LIABILITY CLAIMS, THE DAMAGES MAY EXCEED OUR INSURANCE. It is impossible to fully predict the potential adverse effects that a product candidate may have in humans from the results of studies in animals. Because we conduct clinical trials on humans, we face the risk that the use of our product candidates will result in adverse effects. These risks will exist even for products that may be cleared for commercial sale. Although we maintain liability insurance of $10.0 million for our product candidates in clinical trials, the amount of insurance coverage we currently hold may not be adequate to protect us from any liabilities. Furthermore, coverage is becoming increasingly expensive and we may not be able to maintain or obtain insurance at a reasonable cost or in sufficient amounts to protect us against potential losses. We may not have sufficient resources to pay for any liabilities resulting from a claim beyond the limit of our insurance coverage. CHANGES IN, OR INTERPRETATIONS OF, ACCOUNTING RULES AND REGULATIONS COULD RESULT IN UNFAVORABLE ACCOUNTING CHARGES. Accounting regulations and corporate governance practices are receiving increased scrutiny and continue to be subject to further review, interpretation and guidance from relevant accounting authorities, including the Securities and Exchange Commission, or the SEC. Although we believe that our accounting practices are consistent with current accounting regulations, changes to, or interpretations of, accounting methods or policies in the future may require us to reclassify, restate or otherwise change or revise our financial statements, which may adversely affect our results of operations and business. THE REIMBURSEMENT STATUS OF NEWLY APPROVED HEALTHCARE DRUGS IS UNCERTAIN AND FAILURE TO OBTAIN ADEQUATE REIMBURSEMENT COULD LIMIT OUR ABILITY TO MARKET ANY PRODUCTS WE MAY DEVELOP AND DECREASE OUR ABILITY TO GENERATE REVENUE. There is significant uncertainty related to the reimbursement of newly approved pharmaceutical products. Our ability, and that of our collaborators, to commercialize our products in both domestic and foreign markets will partially depend on the reimbursements obtained from third-party payers such as government health administration authorities, private health insurers, managed care programs and other organizations. Third-party payers are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement of new pharmaceutical products. Cost control initiatives could decrease the price that we, or our collaborators, would receive for our products and affect our ability to commercialize any products we may develop so that the sale of our drugs would not be economically feasible. If third parties fail to provide reimbursement for any drugs we may develop, consumers and physicians may not choose to use our products, and we may not realize an acceptable return on our investment in product development. -21- IF WE ARE UNABLE TO CREATE SALES, MARKETING AND DISTRIBUTION CAPABILITIES OR ENTER INTO AGREEMENTS WITH THIRD PARTIES TO PERFORM THESE FUNCTIONS, WE WILL NOT BE ABLE TO COMMERCIALIZE OUR PRODUCTS. Because we do not have any marketed products, we have virtually no experience in sales, marketing and distribution. To directly market and distribute any products we may develop, we must build a substantial marketing and sales force with appropriate technical expertise and supporting distribution capabilities. Alternatively, we may obtain the assistance of a pharmaceutical company or other entity with a large distribution system and a large direct sales force. We may not be able to establish sales, marketing and distribution capabilities of our own or enter into such arrangements with third parties in a timely manner or on acceptable terms. To the extent that we enter into co-promotion or other licensing arrangements, our product revenues are likely to be lower than if we directly marketed and sold our products, and some or all of the revenues we receive will depend upon the efforts of third parties, which efforts may not be successful. WE USE HAZARDOUS MATERIALS IN OUR BUSINESS AND WE MUST COMPLY WITH ENVIRONMENTAL LAWS AND REGULATIONS, WHICH CAN BE EXPENSIVE. Our research and development activities involve the controlled use of hazardous materials, including chemicals and radioactive and biological materials. Our operations also produce hazardous waste products. We are subject to a variety of federal, state and local regulations relating to the use, handling, storage and disposal of these materials. We generally contract with third parties for the disposal of such substances, and store our low level radioactive waste at our facility until the materials are no longer considered radioactive because there are no facilities permitted to accept such waste in California or neighboring states. We cannot eliminate the risk of accidental contamination or injury from these materials. We may be required to incur substantial costs to comply with current or future environmental and safety regulations. In the event of an accident or contamination, we would likely incur significant costs associated with civil penalties or criminal fines and in complying with environmental laws and regulations. ITEM 2. PROPERTIES We currently lease approximately 42,300 square feet of laboratory and office space in San Diego, California. Our lease expires in September 2006. ITEM 3. LEGAL PROCEEDINGS From time to time, we may be involved in certain litigation arising out of our operations. We maintain liability insurance, including product liability coverage, in amounts our management believes is adequate. We are not currently engaged in any legal proceedings that we expect would materially harm our business or financial condition. However, our evaluation of the likely impact of these actions could change in the future and an unfavorable outcome, depending upon the amount and timing, could have a material adverse effect on our results of operations or our cash flows in a future period. -22- On March 4, 2003, the Asset Value Fund Limited Partnership, or AVF, filed a purported class action complaint against us and our directors in Delaware state court alleging that our Board of Directors violated their fiduciary duties to shareholders when they approved the proposed merger of us and Dendreon Corporation. Specifically, the complaint alleges that (1) the directors failed to consider all available information when deciding to pursue the merger, (2) the directors failed to negotiate a mechanism to protect shareholders from the effects of a decline in Dendreon's stock price before the merger, and (3) a minority of the directors were furthering their own interests in approving the merger instead of the interests of shareholders. AVF seeks to enjoin us from proceeding with the merger, and also seeks compensatory damages and reimbursement of the costs of bringing suit. Neither the Company nor any of our directors has yet been served with the complaint. We deny the material allegations in the complaint and, if the complaint is served, intend to defend the action vigorously. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS None PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS Since 1992, our common stock has traded on the Nasdaq National Market under the symbol "CVAS." The following table sets forth, for the periods indicated, the high and low sales prices of our common stock, as reported on the Nasdaq National Market. HIGH LOW ---- --- 2001 First Quarter....................................... $ 15.00 $ 6.09 Second Quarter...................................... 14.55 7.63 Third Quarter....................................... 12.77 4.98 Fourth Quarter...................................... 7.46 5.00 2002 First Quarter....................................... $ 7.35 $ 5.47 Second Quarter...................................... 6.10 1.79 Third Quarter....................................... 2.35 1.20 Fourth Quarter...................................... 1.75 1.21 2003 First Quarter (through February 28, 2003)........... $ 2.11 $ 1.23 On February 28, 2003, the closing price of our common stock was $1.74 per share, and there were approximately 600 holders of record of our common stock. We have never declared or paid dividends on our capital stock. We anticipate that we will retain our earnings, if any, to support our operations and to finance the growth and development of our business. Therefore, we do not expect to pay cash dividends in the foreseeable future. -23- ITEM 6. SELECTED FINANCIAL DATA This section presents our historical financial data.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS THE FOLLOWING DISCUSSION OF OUR FINANCIAL CONDITION AND RESULTS OF OPERATIONS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. OUR ACTUAL RESULTS MAY DIFFER MATERIALLY FROM WHAT IS DISCUSSED IN THE FORWARD-LOOKING STATEMENTS. FACTORS THAT MIGHT CAUSE SUCH A DIFFERENCE INCLUDE, BUT ARE NOT LIMITED TO, THOSE DISCUSSED ABOVE UNDER THE HEADING "RISK FACTORS." THE TERMS "CORVAS," "WE," "US" AND "OUR" REFER TO CORVAS INTERNATIONAL, INC. OVERVIEW We are a biopharmaceutical company focused on the development of new biotherapeutics that address large medical markets, including cardiovascular disease and cancer. In November 2002 we initiated a Phase II clinical program for rNAPc2 in patients with acute coronary syndromes, which include unstable angina and non-ST-segment elevation myocardial infarction, or UA/NSTEMI. Our cancer research programs are focused on the development of new biotherapies, including monoclonal antibodies and synthetic prodrugs, that target serine proteases associated with the growth and spread of cancerous tumors. On February 25, 2003, we executed a definitive merger agreement under which Dendreon Corporation will acquire us, subject to various closing conditions including approval by the stockholders of each company. Under the terms of this agreement, each share of our common stock will be exchanged for a fixed ratio of 0.45 shares of Dendreon common stock in a tax-free reorganization. The transaction is anticipated to close in the second quarter of 2003, subject to approval by stockholders of both companies. All of the projections, trends and forward-looking statements included herein are based on Corvas operating as a stand-alone entity. In the event that this proposed merger is completed, these projections, trends and forward-looking statements will likely change, and the changes may be significant. We currently have no products for sale and are focused on research and development and clinical trial activities. We have not been profitable on an annual basis since inception and we anticipate that we will incur substantial additional operating losses over the next several years as we progress in our cardiovascular and cancer programs. To date, we have funded our operations primarily through the sale of equity and debt securities, payments received from collaborators and interest income. At December 31, 2002, we had an accumulated deficit of $146.2 million. Unless we enter into any new collaborative agreements that include funding for research and development or funding for the continued development of our drug candidates, we expect that our major source of income, if any, for the next several years will continue to primarily be interest income. We may not enter into any additional collaborative agreements and may not recognize any associated revenue. RESTRUCTURING In July 2002, we initiated a workforce reduction of nearly 40% of our research and administrative staff as part of an extensive strategic realignment of our research and development programs. This restructuring was implemented to focus our resources on the continued clinical development of our proprietary rNAPc2 product candidate and on our cancer research programs focused on therapeutic antibodies and synthetic prodrugs. We expect to realize annualized cost savings estimated at more than $8.0 million from this restructuring and related cost-cutting measures. -25- RESULTS OF OPERATIONS REVENUES. Our 2002 operating revenues decreased to $142,000 from $312,000 in 2001 and $6.1 million in 2000. We recorded no revenues from collaborative agreements or license fees in 2002 and 2001, compared to $5.8 million in 2000. Revenues from collaborative agreements in 2000 included $3.0 million from an agreement with Schering-Plough related to oral anticoagulants for chronic thrombosis, and $263,000 from an agreement with Schering-Plough related to oral inhibitors of the hepatitis C virus. A $2.5 million license fee from Schering-Plough for the hepatitis C inhibitor program was also recognized in 2000. Royalty revenues of $142,000, $117,000 and $167,000 were recognized in 2002, 2001 and 2000, respectively, from our license agreements related to sales of recombinant tissue factor. Due to the completion of a research grant in August 2001, no research grant revenue was recognized in 2002, compared to $195,000 and $198,000 in 2001 and 2000, respectively. RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses, which accounted for 70% of our total costs and expenses in 2002, 82% in 2001 and 79% in 2000, decreased to $16.6 million in 2002 from $24.0 million in 2001. This $7.4 million decrease was attributable to both non-recurring manufacturing costs associated with the manufacturing of rNAPc2 in 2001 and our July 2002 workforce reduction, which also resulted in a realignment of our ongoing research programs. Research and development expenses in 2001 increased to $24.0 million from $14.9 million in 2000. This $9.1 million increase was primarily attributable to rNAPc2 manufacturing costs, as well as growth in the number of scientists along with licensing and patent activities in support of our cancer programs. We expect that our 2003 research and development expenses will continue to be comprised of costs associated with rNAPc2 development as well as our internally-funded cancer research programs. Although our expenses for basic research are expected to decrease as a result of the workforce reduction which primarily impacted our scientists, we expect that our 2003 research and development costs will increase over 2002 due to the recent initiation of our rNAPc2 Phase II clinical program in UA/NSTEMI patients. As of December 31, 2002, we had paid approximately $2.8 million for this trial. We have not prepaid any significant expenses for the second and third parts of this trial. We will continue to incur expenses for the first part of the trial, as we pay a per patient fee and associated costs as each patient is enrolled. GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses in 2002 increased to $5.2 million from $5.1 million in 2001 and $4.1 million in 2000. The 2002 increase of $38,000 compares to a $1.0 million increase in 2001, primarily due to increased facility costs resulting from additional square footage assumed in 2000 and, to a lesser extent, costs associated with hiring a new executive. We expect that our general and administrative expenses in 2003 will increase over the 2002 amounts, mainly due to legal and other costs associated with the proposed merger with Dendreon. RESTRUCTURING CHARGES. In connection with the July 2002 restructuring of nearly 40% of our research and administrative staff, we recorded total restructuring charges of $1.9 million. Approximately 68% or $1.3 million of the total charges were comprised of severance payments and related benefits. Settlement of contractual obligations and legal costs accounted for 15% or $295,000 of the total charges, while 9% or $170,000 was incurred for outplacement services provided to the impacted employees and 8% or $160,000 related to a non-cash charge for impaired assets. Future cash payments of $426,000 are expected to be paid through July 2003 in connection with the restructuring. See Note 4 of the Notes to Financial Statements for more details regarding the restructuring charges. NET OTHER INCOME. Net other income was $2.4 million in 2002, compared to $5.4 million in the previous year. This $3.0 million decrease was due to a combination of lower balances available for investment and the significant -26- reduction in interest rates. Net other income in 2001 increased by $3.2 million over the $2.2 million recognized in 2000. This increase was attributable to the investment of net proceeds from our November 2000 public offering of common stock. Interest income in each of these years was partially offset by interest expense of $841,000, $797,000 and $762,000 in 2002, 2001 and 2000, respectively, attributable to the outstanding convertible notes. As a result of the lower prevailing interest rates and lower balances available for investment, we expect that our interest income will continue to decline. We expect that we will continue to incur substantial additional operating losses for at least the next several years as we pursue our clinical trials and research and development efforts. We also expect both our expenses and losses to fluctuate from year to year and that the fluctuations may, at times, be substantial. LIQUIDITY AND CAPITAL RESOURCES Since inception, our operations have been financed primarily through public offerings and private placements of our debt and equity securities, payments received through collaborative agreements, and interest income earned on cash and investment balances. Our principal sources of liquidity are cash and cash equivalents, time deposits and short- and long-term held to maturity debt securities, which, net of $303,000 in restricted time deposits, totaled $90.2 million as of December 31, 2002. Working capital, which is our current assets minus our current liabilities, was $79.8 million at December 31, 2002. We invest available cash in accordance with an investment policy set by our board of directors. During the year ended December 31, 2002, we used net cash of $20.5 million in our operating activities, $20.4 million of which was provided by our investing activities. Net cash of $172,000 was provided by financing activities in 2002 from the exercise of stock options and purchases of stock through our employee stock purchase plan. In August and October of 1999 we issued and sold, in two private financings, a total of 2,000,000 shares of our common stock for $2.50 per share and 5.5% convertible senior subordinated notes due in August 2006, or the convertible notes, in an aggregate principal amount of $10.0 million. Net proceeds of $14.8 million were raised in these financings. At the option of the note holder, the principal balance of both notes is convertible into shares of our common stock at $3.25 per share, subject to certain adjustments. Interest on the outstanding principal amounts of these convertible notes accretes at 5.5% per annum, compounded semi-annually, with interest payable upon redemption or conversion. Upon maturity, these notes will have an accreted value of $14.6 million. At our option, the accreted interest portion of both notes may be paid in cash or in our common stock priced at the then-current market price. We have agreed to pay any applicable withholding taxes on behalf of the note holder that may be incurred in connection with the accreted interest, which are estimated and accrued at 30% of the annual accretion. We may redeem the convertible notes any time after August 18, 2002 upon payment of the outstanding principal and accreted interest. In the event we are acquired by Dendreon, the note holder may require the redemption of the convertible notes within 30 business days following the change of control. If the holder exercises this right, as is currently expected, then the principal of the convertible notes must be paid in cash and Dendreon will have the option of paying the accreted interest in cash or in Dendreon common stock priced at the average closing price for the 20 trading days immediately prior to the redemption. In April 2002, we entered into an exclusive collaboration agreement with Abgenix, Inc. to discover, develop and commercialize fully-human monoclonal antibodies against two selected antigens from our portfolio of membrane-bound serine proteases. Under the terms of the collaboration, Abgenix will use its human antibody technologies to generate and select antibodies against the Corvas targets. Both companies will have the right to co-develop and commercialize, or, if co-development is not elected, to solely develop and commercialize any antibody products discovered during the collaboration. Both companies will share -27- equally in the product development costs and any profits from sales of products successfully commercialized from any co-development efforts. In September 2001, we entered into a collaboration agreement with Dyax Corp. to discover, develop and commercialize novel cancer therapeutics focused on serine protease inhibitors for two targets that we isolated and characterized. Under the terms of this agreement, both companies will assume joint development of any product candidates that may be identified and will share commercialization rights and profits from any marketed products. In July 2001, we entered into an agreement with Incyte Genomics, Inc. for a multi-year subscription to Incyte's LifeSeq(R) Gold database that was used in certain of our cancer research and development programs prior to our July 2002 restructuring. In January 2003, we terminated this agreement and paid a $100,000 termination fee. For at least the next several years, we expect additional operating losses and negative cash flows from operations. We currently expect our 2003 burn rate to be in the low to mid $20 million range. Our current estimate does not account for any potential strategic transactions and assumes that we proceed with the second and third parts of the ANTHEM/TIMI-32 trial without having a corporate partner in place to fund any of the trial costs. We expect to fund our working capital and capital expenditure requirements during the next 12 months from our available cash and investments. Based on our current estimates, including expected annualized cost savings of more than $8.0 million from our restructuring and other cost-cutting measures, we believe that our available cash and investments should be sufficient to satisfy our anticipated funding requirements for at least the next several years as a stand-alone company. Our material contractual obligations are as follows (in thousands): Payments Due/Estimated by Period -------------------------------- Less than 1 After year 1-3 years 4-5 years 5 years Total (2003) (2004-2006) (2007-2008) (2009 +) ----- ------ ----------- ----------- -------- Commitments(1) -------------- Operating lease $ 5,320 $ 1,345 $ 3,975 $ -0- $ -0- Capital expenditures (2) 268 268 -0- -0- -0- Committed research and development (3) 20,566 3,047 17,147 248 124 Workforce reduction and related costs 426 426 -0- -0- -0- ----------- ----------- ------------ ------------ ------------ Total contractual obligations $ 26,580 $ 5,086 $ 21,122 $ 248 $ 124 =========== =========== ============ ============ ============ _________________ 1 Does not include payment of outstanding principal and accreted interest on the convertible notes as we expect they will be converted into shares of our common stock. This may change for many reasons including, but not limited to, the reasons listed on the next page. 2 Based on 2003 capital purchases and purchase commitments. This estimate is less than our approved capital budget for 2003. This estimate may change for many reasons including, but not limited to, the reasons listed on the next page. 3 Includes committed costs for rNAPc2, assuming that we complete all three parts of our Phase II study, as well as for our cancer programs. Further, assumes various license agreements are not terminated prior to the time period indicated and are renewed annually. These future estimates may change for many reasons including, but not limited to, the reasons listed on the next page. -28- Our current estimate of our future burn rate and capital requirements will change in the event we are acquired by Dendreon. In addition, our estimates may change for many other reasons, some of which are beyond our control, including, but not limited to: o the costs associated with our recently-initiated ANTHEM/TIMI-32 trial, including the timing of the initiation of various parts of the program; o the rate of patient enrollment in all parts of our ANTHEM/TIMI-32 trial; o the timing and magnitude of expenses incurred to further develop and potentially commercialize rNAPc2; o the progress related to our collaboration agreements with Abgenix and Dyax, including the selection of any preclinical candidates; o the progress on, and scope of, our internally-funded cancer programs, including the timing of selection of a clinical drug candidate from our PACT program; o our success in entering into future collaborative agreements, if any; o competing technological and market developments; o the costs we incur in obtaining and enforcing patent and other proprietary rights; o the costs we incur in defending against potential infringement of the patents of others or in obtaining a license to operate under such patents; o the timing and form of payment (cash or common stock) related to repayment of our outstanding convertible notes; and o costs associated with our pending transaction with Dendreon, including, but not limited to, proxy solicitation expenses, legal fees and costs associated with the class action complaint purportedly filed in Delaware state court. Our expected cash requirements may vary materially from those now anticipated for many reasons. In the future we may need to raise additional capital through strategic or other financings or through collaborative relationships. Our ability to raise additional funds through the sale of securities depends in part on investors' perceptions of the biotechnology industry, in general, and of Corvas, in particular. Market prices for securities of biotechnology companies, including Corvas, have historically been highly volatile and may continue to be volatile in the future. Accordingly, additional funding may not be available on acceptable terms or at all. If additional funds are raised by issuing securities, our stockholders will experience dilution, which may be substantial, especially if our stock price remains at the current low levels. If we are not able to raise adequate funds in the future, we may be required to significantly delay, scale back or discontinue one or more of our drug discovery programs, clinical trials or other aspects of our operations. Our net operating loss carryforwards available to offset future taxable income at December 31, 2002 were approximately $140.7 million for federal income tax reporting purposes, and begin to expire in 2003. The net operating loss carryforwards for state purposes, which expire five to ten years after generation, are approximately $81.8 million. We also had unused research and development tax credits for federal income tax reporting purposes of $7.2 million at December 31, 2002. In accordance with Internal Revenue Code Sections 382 and 383, the annual utilization of net operating loss carryforwards and credits existing prior to a change in control may be limited. The extent of such prior limitations, if any, has not been determined. -29- APPLICATION OF CRITICAL ACCOUNTING POLICIES The preparation of our financial statements in accordance with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. These estimates include, among others, revenue recognition, stock-based compensation and research and development expenses. We typically base our estimates on historical experience, terms of existing contracts, trends in the industry, information available from other outside sources, and on various other assumptions that we believe are reasonable under the circumstances. Actual results could vary from these estimates under different assumptions or conditions. Our significant accounting policies, which have been consistently applied in all material respects, are more fully described in Note 2 of our Notes to Financial Statements. We consider certain of these policies to be critical. REVENUE RECOGNITION. Revenues from collaborative agreements are recognized as the related research and development activities are performed under the terms of our agreements; any advance payments received in excess of amounts earned are recorded as deferred revenue and recognized as revenue in accordance with the terms of the agreements. Non-refundable license fees are recognized when we receive such payments, absent any continuing involvement as required by Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements." We recognize milestone payments as revenue upon achievement of the milestones specified in our agreements. Research grant revenues are recognized as the related research is performed under the terms of the grant. We do not currently have any agreements in place under which we expect to recognize any revenue in 2003. STOCK-BASED COMPENSATION. As permitted by Statement of Financial Accounting Standards No. 123, or SFAS 123, "Accounting for Stock-Based Compensation," as amended by Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure, an amendment of FASB Statement No. 123," we have elected to continue to apply the provisions of Accounting Principles Board, or APB, Opinion No. 25, "Accounting for Stock Issued to Employees" and related interpretations in accounting for our employee stock option and stock purchase plans. Accordingly, we recognize no compensation expense in connection with our employee stock option and stock purchase plans. We are required by SFAS 123 to disclose the pro forma effects on our reported net loss and loss per share as if compensation expense had been recognized for these items based on the fair value method of accounting prescribed by SFAS 123. In connection with stock options granted to certain consultants, we must make various valuation assumptions for purposes of recording compensation expense. Had we determined compensation cost for our stock-based plans based on the fair value at the grant date, our net loss and net loss per share would have been increased to the pro forma amounts indicated below (in thousands, except per share data). 2002 2001 2000 ------------- ------------ ------------- Net loss - As reported $ (21,178) $ (23,441) $ (10,689) Net loss - Pro forma $ (26,150) $ (29,709) $ (12,330) Basic and diluted net loss per share - As reported $ (0.77) $ (0.85) $ (0.49) Basic and diluted net loss per share - Pro forma $ (0.95) $ (1.08) $ (0.57) -30- RESEARCH AND DEVELOPMENT EXPENSES. We expense all research and development costs as they are incurred. Our research and development costs include, but are not limited to, payroll and related costs, lab supplies, clinical and preclinical studies, manufacturing costs for clinical supplies, sponsored research at other labs, consulting, legal patent fees and research-related overhead charges. Our accrued liabilities for research and development expenses are based, in part, on a number of estimates that are related to our clinical, preclinical and other studies. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS In December 2002, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards No. 148, or SFAS 148, "Accounting for Stock-Based Compensation - Transition and Disclosure, an amendment of FASB Statement No. 123." SFAS 148 enables companies that choose to adopt the fair value based method to report the full effect of employee stock options in their financial statements immediately upon adoption. We will continue to apply the disclosure-only provisions of SFAS 123. See Notes 2 and 6 of our Notes to Financial Statements for additional information regarding our treatment of stock options. The transition provisions of SFAS 148 are effective for fiscal years ending after December 15, 2002. The disclosure provisions are effective for financial reports containing condensed financial statements for interim periods beginning after December 15, 2002. In November 2002, the FASB published Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others." Interpretation No. 45 expands on the accounting guidance of Statements of Financial Accounting Standards Nos. 5, 57, and 107, and incorporates without change the provisions of FASB Interpretation No. 34, which is being superseded. Interpretation No. 45 elaborates on the existing disclosure requirements for most guarantees, including loan guarantees such as standby letters of credit. Further it requires companies to recognize an initial liability for the fair value, or market value, of the obligations it assumes under that guarantee and must disclose that information in its interim and annual financial statements at the time a guarantee is issued. The initial recognition and measurement provisions apply on a prospective basis to guarantees issued or modified after December 31, 2002, regardless of the guarantor's fiscal year end. The disclosure requirements in Interpretation No. 45 are effective for financial statements of interim or annual periods ending after December 15, 2002, and are not expected to have a material effect on our financial statements. In July 2002, the FASB issued Statement of Financial Accounting Standards No. 146, or SFAS 146, "Accounting for Restructuring Costs," which applies to costs associated with an exit activity, including restructuring, or with a disposal of long-lived assets. SFAS 146 requires that a liability be recorded for costs associated with an exit or disposal activity when that liability is incurred and can be measured at fair value, rather than at the date of commitment to an exit activity. SFAS 146 also requires disclosures about exit and disposal activities, the related costs, and changes in those costs in the notes to the financial statements that include the period in which an exit activity is initiated and in any subsequent period until the activity is completed. SFAS 146 is effective prospectively for exit or disposal activities initiated after December 31, 2002. We do not expect the adoption of SFAS 146 to have a material effect on our financial statements. -31- ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK In accordance with our investment policy, we do not invest in derivative financial instruments or any other market risk sensitive instruments. Our available cash is invested in high quality, fixed income investments that we intend to hold to maturity. See Note 2 of our Notes to Financial Statements for information about these financial instruments. We believe that our interest rate market risk is limited, and that we are not exposed to significant changes in fair value because our investments are held to maturity and are primarily short-term in nature. The fair value of each investment approximates its amortized cost. For purposes of measuring interest rate sensitivity, we have assumed that the similar nature of our investments allows us to aggregate their value. The carrying amount of all held to maturity investments as of December 31, 2002 is $85.7 million, and they have a weighted-average interest rate of 2.6%. These investments mature at various dates through August 18, 2004. Considering our investment balances as of December 31, 2002, rates of return and the fixed rate nature of the convertible notes payable that were issued in the second half of 1999, an immediate 10% change in interest rates would not have a material impact on our financial condition or results of operations. Since the $10.0 million aggregate principal of the 5.5% convertible senior subordinated notes that we issued is convertible into common stock at $3.25 per share at the option of the holder, there is underlying market risk related to an increase in our stock price or an increase in interest rates that may make conversion of these notes into common stock beneficial to the holder. Conversion of these convertible notes will have a dilutive effect on our common stock. ITEM 8.

F-5 CORVAS INTERNATIONAL, INC. Notes to Financial Statements December 31, 2002 and 2001 (l) The Company ----------- Corvas International, Inc. (the "Company") was incorporated on March 27, 1987 under the laws of the State of California. In July 1993, the Company reincorporated in the State of Delaware. The Company is focused on the discovery and development of novel therapeutics that address today's largest medical markets, cardiovascular disease and cancer, based on the Company's expertise in vascular biology and protease modulation. (2) Summary of Significant Accounting Policies ------------------------------------------ (a) Cash Equivalents: ----------------- Cash equivalents consist of investments in short-term government funds and a high-quality money market fund with original maturities of three months or less. Cash equivalents are stated at cost, which approximates market value. (b) Debt Securities Held to Maturity and Time Deposits: --------------------------------------------------- Short-term debt securities consist of highly liquid debt instruments of corporations and financial institutions with strong credit ratings and U.S. government obligations. The Company has the ability and intent to hold its investments until their maturity and, therefore, records its investments at amortized cost, which approximates market value. Short-term debt securities mature at various dates through December 31, 2003. Long-term debt securities have a maturity of more than twelve months as of December 31, and consist of highly liquid debt instruments of corporations and financial institutions with strong credit ratings. Long-term debt securities, all of which are held to maturity, are stated at amortized cost. The market value of long-term debt securities was $12.3 million as of December 31, 2002. Long-term debt securities mature at various dates through August 18, 2004. At both December 31, 2002 and 2001, time deposits of $303,000 were restricted related to the facility lease. See Note 8. (c) Concentration of Credit Risk: ----------------------------- Cash, cash equivalents and debt securities are financial instruments that potentially subject the Company to concentration of credit risk. The Company's investment policy establishes guidelines relative to diversification, maturities and minimum acceptable credit ratings to maintain safety and liquidity. As of December 31, 2002, the Company has not experienced any material losses on its investments. During the years ended December 31, 2002 and 2001, certain securities that were no longer in compliance with the Company's investment policy were sold prior to maturity due to downgrading of credit ratings. (d) Depreciation and Amortization: ------------------------------ Depreciation is provided using the straight-line method over estimated useful lives of three to five years. Leasehold improvements are amortized on a straight-line basis over the shorter of the lease terms or estimated useful lives of the assets. (e) Research and Development Costs: ------------------------------- Research and development costs are expensed in the period incurred. (f) Patents: -------- Costs to obtain and maintain patents are expensed as incurred. F-6 CORVAS INTERNATIONAL, INC. Notes to Financial Statements, Continued (g) Net Loss per Share: ------------------- Under Statement of Financial Accounting Standards No. 128, "Earnings per Share" ("SFAS 128"), basic and diluted net loss per share are required to be presented. Basic net loss per share is calculated using the weighted-average number of common shares outstanding during the period, while diluted net loss per share also includes potential dilutive common shares outstanding. Potential common equivalent shares from convertible securities, stock options and warrants are excluded from the calculation of diluted loss per share since the effect of their inclusion would be anti-dilutive; accordingly, there is no difference between the Company's basic and diluted net loss per share. For the years ended December 31, 2002, 2001 and 2000, 3,573,000, 3,237,000 and 2,248,000 options, respectively, were excluded from the calculation of dilutive net loss per share. In addition, 3,682,000, 3,488,000 and 3,303,000 shares from the assumed conversion of the 5.5% convertible senior subordinated notes issued in 1999 (see Note 5) were also excluded from this calculation for the years ended December 31, 2002, 2001 and 2000, respectively. (h) Accounting for Stock-Based Compensation: ---------------------------------------- As permitted by Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), as amended by Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure, an amendment of FASB Statement No. 123," the Company has elected to use the intrinsic value-based method as prescribed in Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees" and related interpretations. If the Company had determined compensation cost for its stock-based plans based on the fair value at the grant date, the Company's net loss and net loss per share would have been increased to the pro forma amounts indicated below (in thousands, except per share data). 2002 2001 2000 ------------ ------------- ------------- Net loss - As reported $ (21,178) $ (23,441) $ (10,689) Net loss - Pro forma $ (26,150) $ (29,709) $ (12,330) Basic and diluted net loss per share - As reported $ (0.77) $ (0.85) $ (0.49) Basic and diluted net loss per share - Pro forma $ (0.95) $ (1.08) $ (0.57) The following weighted-average assumptions were used in calculating compensation cost for stock-based plans under SFAS 123: 2002 2001 2000 ------------- ------------ ------------- Expected dividend yield 0% 0% 0% Risk-free interest rate 3.99% 4.29% 5.57% Expected life 6.71 years 7.74 years 7.31 years Expected volatility 78.86% 81.67% 81.69% (i) Revenue Recognition: -------------------- Revenue from collaborative agreements typically consists of non-refundable research and development funding under collaborative agreements with strategic partners. Revenue from collaborative agreements is recognized as the related research and development activities are performed under the terms of the agreements; any advance payments received in excess of amounts earned are recorded as deferred revenue and recognized as revenue in accordance with the terms of the agreements. License fees consist of non-refundable fees from the sale of rights under collaborative development and/or license agreements with strategic partners. Non-refundable license fees are recognized as revenue upon receipt, absent any continuing involvement as required by Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB 101"). Product development milestone payments, as specified in various collaborative agreements, are recognized as revenue upon achievement of the milestones specified in the agreements. Research grant revenue is recognized as the related research is performed under the terms of the grant. F-7 CORVAS INTERNATIONAL, INC. Notes to Financial Statements, Continued (j) Income Taxes: ------------- Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. (k) Use of Estimates: ----------------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management of the Company to make a number of estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes to financial statements. Actual results could differ from these estimates under different assumptions or conditions. (l) Fair Value of Financial Instruments: ------------------------------------ Statement of Financial Accounting Standards No. 107, "Disclosures about Fair Value of Financial Instruments" ("SFAS 107"), defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. The carrying value of cash and cash equivalents, short-term debt securities held to maturity, time deposits, receivables, other current assets, accounts payable, accrued liabilities, accrued benefits, accrued leave and accrued restructuring, included in the accompanying balance sheets, approximate the estimated fair value of those instruments because of their short-term nature. The carrying values of the long-term debt securities held to maturity approximate fair value due to the nature of these securities. (m) Impairment of Long-Lived Assets: -------------------------------- Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144") requires losses from impairment of long-lived assets used in operations to be recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying amount. The Company periodically evaluates the carrying value of long-lived assets to be held and used when events and circumstances indicate that the carrying amount of an asset may not be recovered. During the year ended December 31, 2002, the Company recorded an impairment charge of $160,000 in connection with its July 2002 restructuring. See Note 4. (n) Segment Reporting: ------------------ Statement of Financial Accounting Standards No. 131, "Disclosures About Segments of an Enterprise and Related Information" ("SFAS 131"), establishes reporting standards for a Company's operating segments and related disclosures about its products, services, geographic areas and major customers. An operating segment is defined as a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, and about which separate financial information is regularly evaluated by management in deciding how to allocate resources. The Company believes that it operates in a single segment, biopharmaceuticals. F-8 CORVAS INTERNATIONAL, INC.

This restructuring was part of an extensive strategic realignment of research programs designed to focus the Company's resources on the continued development of its most-advanced cardiovascular and cancer programs. Summary information related to the restructuring as of December 31, 2002 is included in the table below (in thousands).

Net proceeds of $14.8 million were raised in these financings. At the option of the note holder, the principal balance of both notes is convertible into shares of common stock at $3.25 per share, subject to certain adjustments. Interest on the outstanding principal amounts of these notes accretes at 5.5% per annum, compounded semi-annually, with interest payable upon redemption or conversion. Upon maturity, these notes will have an accreted value of $14.6 million. At the Company's option, the accreted interest portion of both notes may be paid in cash or in common stock priced at the then-current market price. The Company agreed to pay any applicable withholding taxes on behalf of the note holder that may be incurred in connection with the accreted interest, which are estimated and accrued at 30% of the annual accretion. The Company may redeem the notes upon payment of the outstanding principal and accreted interest. The maximum number of shares that will be issued upon conversion of these notes is 4,484,000 shares of common stock, which have been reserved for the potential conversion of these notes. Interest expense of $841,000, $797,000 and $762,000 was recorded for the years ended December 31, 2002, 2001 and 2000, respectively, related to both of the convertible notes. F-9 CORVAS INTERNATIONAL, INC. Notes to Financial Statements, Continued (6) Stockholders' Equity -------------------- (a) Common Stock: ------------- In November 2000, the Company issued and sold 5,750,000 shares of common stock in a public offering, which resulted in net proceeds of $107.4 million. During the year ended December 31, 2000, the Company issued a total of 2,204,000 shares of common stock pursuant to the exercise of outstanding warrants, which resulted in aggregate net proceeds of $11.9 million. (b) Stock Option Plans: ------------------- The Company has several plans and agreements under which incentive stock options, non-statutory stock options, restricted stock awards and stock bonus awards can be granted to key personnel, including officers, directors and outside consultants. The grants are authorized by the Human Resources Committee of the Board of Directors. A total of 4,966,000 options to purchase shares of common stock are authorized for issuance as of December 31, 2002, and 631,000 shares of common stock are reserved for future grant. Stock options generally have a term of 10 years and a price per share equal to the fair market value on the date of grant. Annual grants to outside directors have an exercise price equal to 85% of the fair market value on the date of grant, and certain grants to outside consultants have a term of less than 10 years. Most options, except for certain grants to outside consultants and a 2002 grant made to all non-executive employees, become exercisable over a four-year period beginning one year from the date of grant, vesting 25% at the end of the first year and 6.25% each quarter thereafter. Activity under these plans is as follows (in thousands, except per share data): Number of Shares Weighted-Average Under Option Exercise Price per Share ------------------------- ---------------------------- Outstanding, December 31, 1999 2,234 $ 3.79 Granted 739 $ 15.19 Exercised (604) $ 3.96 Cancelled (121) $ 4.37 -------- Outstanding, December 31, 2000 2,248 $ 7.46 Granted 1,067 $ 7.70 Exercised (115) $ 3.01 Cancelled (48) $ 8.29 -------- Outstanding, December 31, 2001 3,152 $ 7.69 Granted 1,076 $ 1.95 Exercised (8) $ 3.34 Cancelled (647) $ 7.35 -------- Outstanding, December 31, 2002 3,573 $ 6.03 ======== F-10 CORVAS INTERNATIONAL, INC.

Accordingly, stock compensation expense is recorded on the date of grant only when options are granted to outside consultants. If the Company had determined compensation cost for its stock-based plans based on the fair value at the grant date, the Company's net loss and net loss per share would have been increased to the pro forma amounts indicated below (in thousands, except per share data). 2002 2001 2000 ------------ ------------- ------------- Net loss - As reported $ (21,178) $ (23,441) $ (10,689) Net loss - Pro forma $ (26,150) $ (29,709) $ (12,330) Basic and diluted net loss per share - As reported $ (0.77) $ (0.85) $ (0.49) Basic and diluted net loss per share - Pro forma $ (0.95) $ (1.08) $ (0.57) The per share weighted-average fair market value of stock options granted during 2002, 2001 and 2000 at exercise prices equal to the fair market value on the date of grant was $1.29, $5.80 and $13.09, respectively, using the Black-Scholes option-pricing model. The per share weighted-average fair market value of stock options granted during 2002, 2001 and 2000 at exercise prices less than the fair market value on the date of grant was $4.85, $10.61 and $8.35, respectively, on the date of grant.

In April 2000, the ESPP was amended to provide for the issuance of up to 350,000 shares of common stock. The ESPP is intended to qualify under Section 423 of the Internal Revenue Code and is for the benefit of qualifying employees, as designated by the Human Resources Committee of the Board of Directors. Under the terms of the ESPP, participating employees are eligible to have a maximum of 10% of their compensation withheld through payroll deductions to purchase shares of common stock at the lower of 85% of the fair market value (i) at the beginning of each offering period or (ii) on predetermined dates. As of December 31, 2002, 277,000 shares of common stock have been issued pursuant to the ESPP and 73,000 shares of common stock are reserved for future issuance. F-11 CORVAS INTERNATIONAL, INC. Notes to Financial Statements, Continued (e) Warrants: --------- During the year ended December 31, 2000, warrants were exercised to purchase a total of 2,204,000 shares of common stock at a weighted-average exercise price of $5.38 per share. As of December 31, 2002 and 2001, no warrants remained outstanding. (f) Stockholder Rights Plan: ------------------------ In September 1997, the Company adopted a stockholder rights plan and declared a dividend distribution of one preferred share purchase right (a "Right") for each outstanding share of common stock ("Common Shares"), effective for stockholders of record as of October 15, 1997 ("Record Date"). The Rights also attach to new Common Shares issued after the Record Date. Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share of Series C Junior Participating Preferred Stock, par value $0.001, at an exercise price of $50 (the "Purchase Price"). The Rights will become exercisable only if a person or group acquires 20% or more of the common stock or announces a tender offer for 20% or more of the common stock in a transaction not approved by the Board of Directors. If the Rights become exercisable, all holders of Rights, except the acquirer of more than 20% of the common stock, will be entitled to acquire for the Purchase Price that number of Common Shares having a market value of two times the Purchase Price of the Right, in lieu of purchasing Series C Junior Participating Preferred Stock. This Right will commence on the date of public announcement that a person has become an Acquiring Person (as defined in the Rights Agreement) or the effective date of a registration statement relating to distribution of the Rights, if later, and terminate 60 days later (subject to certain provisions in the Rights Agreement). The Rights will expire on September 18, 2007, unless exchanged or redeemed prior to that date. Until a Right is exercised, the holder of these Rights will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. See Note 13. (7) Income Taxes ------------ Income tax expense was zero for each of the years in the three-year period ended December 31, 2002, and differed from the amounts computed by applying the U.S. federal income tax rate of 34% to pretax loss as a result of the following (in thousands). 2002 2001 2000 -------------- -------------- ------------- Computed "expected" tax benefit $ (7,201) $ (7,970) $ (3,634) State and local income taxes, net of federal benefit 1 1 1 Credits (1,051) (939) (263) Other (1,424) 2,747 (10) Change in federal valuation allowance 9,675 6,161 3,906 ----------- ----------- ------------ $ --- $ --- $ --- =========== =========== ============ The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2002 and 2001 are presented below (in thousands). 2002 2001 ------------ ------------ Deferred tax assets: Fixed assets $ 207 $ 217 Net operating loss carryforwards 52,183 43,146 Credits 11,033 8,679 Stock options 2,799 2,524 Other 844 118 ------------ ------------ Total gross deferred tax assets 67,066 54,684 Less valuation allowance (67,066) (54,684) ------------ ------------ Net deferred tax assets $ --- $ --- ============ ============ F-12 CORVAS INTERNATIONAL, INC. Notes to Financial Statements, Continued The Company has no net, taxable temporary differences that would require recognition of deferred tax liabilities. Due to management's belief of the uncertainty of future realizability of deferred tax assets, the Company has recorded a valuation allowance against any net deferred tax assets for deductible temporary differences, tax operating loss carryforwards and tax credits. The Company increased its valuation allowance by approximately $12.4 million, $7.2 million and $7.7 million for the years ended December 31, 2002, 2001 and 2000, respectively, primarily as a result of the increase in tax operating loss carryforwards. The valuation allowance includes approximately $2.8 million related to stock option deductions, the benefit of which will eventually be credited to equity. At December 31, 2002, the Company had available net operating loss carryforwards of approximately $140.7 million for federal income tax reporting purposes that begin to expire in 2003. The net operating loss carryforwards for state purposes, which expire five to ten years after generation, are approximately $81.8 million. The Company has unused research and development tax credits for federal income tax purposes of $7.2 million at December 31, 2002, which begin to expire in 2003. In accordance with Internal Revenue Code Sections 382 and 383, the annual utilization of net operating loss carryforwards and credits existing prior to a change in control may be limited. The extent of such prior limitations, if any, has not been determined. (8) Commitments and Contingencies ----------------------------- (a) Lease Commitments: ------------------ The Company currently leases its principal facility under a noncancellable operating lease that expires in September 2006. The lease provides for escalating rent payments over the term of the lease. For financial reporting purposes, rent expense is recognized on a straight-line basis over the lease term. Accordingly, rent expense recognized in excess of cash rent paid is reflected as deferred rent. Total rent expense recognized under this lease for the years ended December 31, 2002, 2001 and 2000 was $1.3 million, $1.3 million and $1.2 million, respectively. The annual future minimum commitments under the facility lease for years ending December 31 are as follows (in thousands). 2003 $ 1,345 2004 1,392 2005 1,441 2006 1,142 ---------- Total minimum lease payments $ 5,320 ========== (b) Letter of Credit: ----------------- The Company has an unused standby letter of credit in the amount of $303,000 that expires on September 30, 2003, with provisions for annual renewal. This letter of credit, collateralized by a $303,000 time deposit, is pledged in lieu of a security deposit against the principal facility lease. (c) Litigation Contingencies: ------------------------- The Company is involved in routine litigation arising in the ordinary course of business. While the results of such litigation cannot be predicted with certainty, the Company believes, in part based on the advice of legal counsel, that the final outcome of such matters will not have a material adverse effect on the Company's financial position or results of operations. F-13 CORVAS INTERNATIONAL, INC. Notes to Financial Statements, Continued (d) Change in Control Arrangements: ------------------------------- In March 2002, the Board of Directors adopted the 2002 Change in Control Executive Severance Benefit Plan ("the Change in Control Plan"). The Change in Control Plan provides separation pay and benefits to each of our executive officers whose employment is involuntarily terminated without cause or voluntarily terminated for good reason during the period beginning one month before and ending 13 months following the effective date of a change in control of the Company. (9) Collaborative Agreements ------------------------ In June 2002, Pfizer Inc. terminated the license and development agreement originally entered into in 1997 to collaborate with the Company on the development of UK-279,276, or rNIF, an anti-inflammatory agent. Pfizer returned exclusive, worldwide development and commercialization rights for rNIF to the Company. In April 2002, the Company entered into an exclusive collaboration agreement with Abgenix, Inc. to discover, develop and commercialize fully-human monoclonal antibodies against two selected antigens from the Company's portfolio of membrane-bound serine proteases. Under the terms of the collaboration, Abgenix will use its human antibody technologies to generate and select antibodies against the Corvas targets. Both companies will have the right to co-develop and commercialize, or, if co-development is not elected, to solely develop and commercialize any antibody products discovered during the collaboration. Both companies will share equally in the product development costs and any profits from sales of products successfully commercialized from any co-development efforts. In September 2001, the Company entered into a collaboration agreement with Dyax Corp. to discover, develop and commercialize novel cancer therapeutics focused on serine protease inhibitors for two targets isolated and characterized by Corvas. Under the terms of this agreement, both companies will assume joint development of any product candidates that may be identified and will share commercialization rights and profits from any marketed products. In July 2001, the Company entered into an agreement with Incyte Genomics, Inc. for a multi-year subscription to Incyte's LifeSeq(R) Gold database that was used in certain of the Company's cancer research and development programs. The Company gave notice to Incyte of its intent to terminate this agreement; accordingly the $100,000 termination fee has been included in restructuring charges on the accompanying statements of operations. This agreement also required us to pay an annual access fee. Included in research and development expenses on the accompanying statements of operations is $500,000 in 2002 and $246,000 in 2001 attributable to this agreement. In May 2000, the Company and Schering-Plough amended the license and collaboration agreement originally entered into in 1997 that covers the design and development of an oral inhibitor of a key protease associated with hepatitis C virus replication, resulting in the recognition of a $2.5 million license fee in 2000. The Company also recognized $263,000 of revenue from collaborative agreements attributable to this collaboration in 2000. Under the terms of the amended agreement, Schering-Plough has an exclusive worldwide license to selected patents and other intellectual property related to hepatitis C virus replication, and is responsible for the conduct of any further research and development, if any. We have no continuing involvement with respect to the research and development of inhibitors of the hepatitis C virus. In December 1994, the Company entered into a strategic alliance agreement with Schering-Plough to collaborate on the discovery and commercialization of an oral anticoagulant for chronic thrombosis. Under the terms of the agreement, Schering-Plough funded the Company's research and development through December 31, 2000. The accompanying statements of operations reflect revenue from collaborative agreements pursuant to this collaboration of $3.0 million in 2000. Schering-Plough is responsible for the conduct of any further research and development, if any. We have no continuing involvement with respect to the further research and development of oral anticoagulants. In conjunction with this agreement, Schering-Plough purchased 1,000,000 shares of Series A Convertible Preferred Stock of the Company in 1994, which resulted in net proceeds of $4.9 million and 250,000 shares of Series B Convertible Preferred Stock in 1996, which yielded net proceeds of $2.0 million. Both series of preferred stock converted to common stock in February 2000. F-14 CORVAS INTERNATIONAL, INC. Notes to Financial Statements, Continued In November 1998, the Company entered into license agreements transferring manufacturing activities for recombinant tissue factor to two affiliates of Johnson & Johnson, superceding earlier agreements entered in June 1992. These agreements continue to provide for royalties to be paid to the Company based on unit sales of tissue factor. For the years ended December 31, 2002, 2001 and 2000, these royalties amounted to $142,000, $117,000 and $167,000, respectively. (10) Employee Benefits Plan ---------------------- Effective January 1, 1988, the Board of Directors approved the Corvas International, Inc. 401(k) Compensation Deferral Savings Plan (the "401(k) Plan"), adopting provisions of the Internal Revenue Code Section 401(k). The 401(k) Plan was approved by the IRS in 1989, and has been previously amended and restated as of January 1, 1997. The 401(k) Plan is for the benefit of all qualifying employees, and permits employee voluntary contributions, qualified nonelective contributions and Company profit-sharing contributions. No employer contributions have been approved by the Board of Directors through December 31, 2002. (11) Related Party Transaction ------------------------- The note receivable from related party of $250,000 as of December 31, 2001 consisted of a loan, evidenced by an amended promissory note, originally granted to an executive officer of the Company in connection with the officer's relocation to San Diego. This amended note was repaid in full in 2002. (12) Research Grant -------------- Pursuant to a Small Business Innovation Research (SBIR) grant from the National Institute for Allergy and Infectious Disease that ended in 2001, research grant revenue of $195,000 and $198,000 was recognized in 2001 and 2000, respectively. The related expenses, which equal research grant revenues, are recorded as research and development expenses in the accompanying statements of operations. (13) Subsequent Event ---------------- On February 25, 2003, Corvas announced the signing of a definitive merger agreement under which Dendreon Corporation will acquire Corvas, subject to various closing conditions including approval by the stockholders of each company. Under the terms of this agreement, each share of Corvas common stock will be exchanged for a fixed ratio of 0.45 shares of Dendreon common stock in a tax-free reorganization. Upon successful closing of this transaction, Corvas' existing stockholders will own approximately 31.4% of the combined company. The transaction is anticipated to close in the second quarter of 2003, subject to approval by stockholders of both companies. In connection with the Dendreon merger agreement, the Company entered into Amendment No. 1 to its Rights Agreement, which excluded the proposed merger. See Note 6. On March 4, 2003, the Asset Value Fund Limited Partnership ("AVF") filed a purported class action complaint against the Company and its directors in Delaware state court alleging that the Board of Directors violated their fiduciary duties to shareholders when they approved the proposed merger of the Company and Dendreon Corporation. Specifically, the complaint alleges that (1) the directors failed to consider all available information when deciding to pursue the merger, (2) the directors failed to negotiate a mechanism to protect shareholders from the effects of a decline in Dendreon's stock price before the merger, and (3) a minority of the directors were furthering their own interests in approving the merger instead of the interests of shareholders. AVF seeks to enjoin the Company from proceeding with the merger, and also seeks compensatory damages and reimbursement of the costs of bringing suit. Neither the Company nor any of its directors has yet been served with the complaint. The Company denies the material allegations in the complaint and, if the complaint is served, intends to defend the action vigorously. F-15 PART III ITEM 10.

BOARD COMMITTEES AND MEETINGS During 2002, the Board held four regularly scheduled meetings, one special meeting and acted by unanimous written consent one time without a meeting. We have four standing committees of the Board: a Human Resources Committee, an Audit Committee, a Governance and Nominating Committee and an Executive Committee. The Human Resources Committee currently consists of Ms. Vitullo as Chairwoman, Dr. Ingle and Dr. Sobel. The Human Resources Committee adopted a new written charter in 2002 that specifies that this committee shall have at least two members, comprised solely of independent, non-employee directors. The Human Resources Committee is authorized to exercise all powers and authority of the Board in all compensation matters, including the establishment of rates of salary, bonuses, retirement and other compensation for all directors, officers and such other personnel of the Company as the Board may from time to time designate. It is also authorized to exercise the authority of the Board in the administration of the Company's 1991 Incentive and Compensation Plan, or the 1991 Plan, the Company's 2000 Equity Incentive Plan, or the 2000 Plan, and the Company's Employee Stock Purchase Plan, or the ESPP. The Human Resources Committee held four regularly scheduled meetings and one special meeting during 2002.

The Audit Committee adopted a written charter in 2000 that specifies that the Audit Committee shall have at least three members, comprised solely of independent directors, each of whom has a working familiarity with basic finance and accounting practices. In addition, at least one member of the Audit Committee must have accounting or related financial management experience. The primary function of the Audit Committee is to assist the Board in fulfilling its responsibilities to the stockholders and the investment community relating to our corporate accounting and reporting practices, and the quality and integrity of our financial reports. The Audit Committee held seven regularly scheduled meetings during 2002. -35- The Governance and Nominating Committee, which was established by our Board in March 2002, currently consists of Ms. Bayh as Chairwoman, Dr. Ingle and Ms. Vitullo. This committee adopted a written charter in 2002 that specifies the Governance and Nominating Committee shall have at least three members, comprised solely of independent directors. The primary function of the Governance and Nominating Committee is to assist the Board with oversight of the integrity of the corporate governance process to ensure compliance with the standards for good corporate governance and to serve as a nominating committee for the Board. The Governance and Nominating Committee works in conjunction with the Board to interview and evaluate candidates for the directorships which become vacant and to make recommendations to the Board concerning the nomination of such candidates. The Governance and Nominating Committee held two regularly scheduled meetings during 2002. The Executive Committee consists of Dr. Ingle as Chairman, Ms. Vitullo and Mr. Woods. The Executive Committee is authorized to exercise the full authority of the Board except with respect to (i) those matters not permitted under the Delaware General Corporation Law to be delegated to any committee, (ii) approval of Company obligations in amounts greater than $200,000, (iii) approval of annual operating plans, business plans and major strategic decisions, and (iv) approval of other major transactions such as corporate partnerships or financing plans. The Executive Committee did not hold any meetings during 2002. During 2002, all directors attended at least 75% of the Board meetings held, except for Dr. Sobel who attended three of five, or 60%, of the Board meetings held due to scheduling conflicts. During 2002, all members of committees of the Board attended at least 75% of the committee meetings in which they were entitled to participate. SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934, or the Exchange Act, requires our directors and executive officers, and persons who own more than 10% of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other of our equity securities. Specific due dates for these reports have been established, and we are required to disclose any failure to file by these dates during 2002. Our officers, directors and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. Based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required during 2002, we believe that our officers, directors and greater than 10% beneficial owners complied with all applicable Section 16(a) filing requirements. ITEM 11. EXECUTIVE COMPENSATION COMPENSATION OF DIRECTORS Members of our Board who are employees of the Company or who are representatives of principal stockholders do not receive compensation for service as directors or for service as members of any committee of the Board. Drs. Sobel and Sorell, Ms. Bayh and Ms. Vitullo each currently receive compensation at the rate of $15,000 per year for their service as a non-employee director who is not a representative of one of our principal stockholders. Dr. Ingle is compensated at the rate of $20,000 per year for service as Chairman of the Board unaffiliated with any principal stockholder. During the year ended December 31, 2002, the total compensation paid to outside directors in connection with their service as directors was $80,000. Members of our Board are also reimbursed for their expenses incurred in connection with attendance at Board meetings in accordance with Company policy. -36- Pursuant to the 2000 Plan, each of our non-employee directors receives, on the first business day of each year, an annual non-discretionary stock option grant to purchase 8,000 shares of our common stock at an exercise price equal to 85% of the fair market value of the common stock on the date of grant. Our fair market value is defined as the average of the high and low sales price reported on The Nasdaq Stock Market for the date of grant. Further, each new non-employee director receives a one time stock option grant to purchase 15,000 shares of our common stock at an exercise price equal to 85% of the fair market value of the common stock on the date of grant. However, a non-employee director is not entitled to an annual grant if he or she received an initial grant in that same year or within 6 months of the initial grant. Options granted to non-employee directors under the 2000 Plan generally vest over a four-year period, 25% on the first anniversary of the grant date and 6.25% each quarter thereafter until fully vested, and have a maximum term of 10 years from the grant date. Under the 2000 Plan, upon certain corporate events resulting in a change in control of the Company, the surviving or acquiring corporation must assume or replace any outstanding options with substitute options. In the event the surviving or acquiring corporation refuses to assume or replace the outstanding options, the outstanding options will be accelerated in full and will terminate if not exercised at or prior to such event. Options granted to non-employee directors under the 1991 Plan became exercisable at the rate of 25% per year over four years, with a maximum term of 10 years from the grant date. Under the 1991 Plan, upon certain corporate events resulting in a change in control of the Company, at the discretion of the Board, the vesting of the outstanding options will accelerate for a period of 30 days prior to such event and the options will terminate if not exercised prior to the consummation of the transaction if the outstanding options are not assumed or substituted with equivalent options by the successor corporation. Options granted to non-employee directors under the 1991 Plan and the 2000 Plan are not intended to qualify as incentive stock options under the Internal Revenue Code of 1986, as amended, or the Code, nor do they disqualify the members of the Human Resources Committee from granting stock awards which, pursuant to Rule 16b-3, are exempt from the application of Section 16 of the Exchange Act. During the year ended December 31, 2002, pursuant to the 2000 Plan, we granted to non-employee directors options to purchase an aggregate of 48,000 shares at an exercise price of $5.4613, which represented 85% of the fair market value on the date of grant. On January 2, 2003, pursuant to the 2000 Plan, we granted to non-employee directors options to purchase an aggregate of 48,000 shares at an exercise price of $1.3388 which represented 85% of the fair market value on the date of grant.

As of February 28, 2003, options to purchase a total of 1,206,158 shares were outstanding under the 1991 Plan, stock awards totaling 5,400 shares of our common stock had been made under the 1991 Plan, and no shares remain available for grant thereunder.

Upon a change in control, the consequences to all outstanding options to purchase common stock granted under the 2000 Plan are described under the heading, "Executive Compensation, Compensation of Directors." (2) Based on an aggregate of 1,023,400 options granted to employees in 2002, including the above grants. This is not necessarily indicative of the number of options that will be granted in the future. (3) The exercise price is equal to 100% of the fair market value of our common stock on the date of grant. (4) The 5% and 10% assumed rates of appreciation are suggested by the rules of the SEC and do not represent our estimate or projection of our future common stock price. (5) The potential realizable value is calculated based on the term of the option at the time of grant (10 years in all cases above). It is calculated by assuming that the stock price on the date of grant appreciates at the indicated annual rate, compounded annually for the entire term of the option, and that the option is exercised and sold on the last day of its term for the appreciated stock price. No gain to the optionee is possible unless the stock price increases over the option term, which will benefit all stockholders. For example, a stockholder who purchased one share of stock on December 12, 2002 at $1.585, held the stock for 10 years and sold it on December 11, 2012 while the stock appreciated at 5% and 10% compounded annually, would have profits of $1.00 and $2.53, respectively, on his $1.585 investment. -40- AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES The following table sets forth certain information regarding stock options exercised by our executive officers during the year ended December 31, 2002, and the number and value of securities underlying unexercised options held by these officers as of December 31, 2002.

Options granted under both the 1991 Plan and the 2000 Plan generally vest over a four-year period, 25% on the first anniversary of the grant date and 6.25% each quarter thereafter until fully vested, and have a maximum term of 10 years from the grant date, subject to earlier termination upon the optionee's cessation of service with us. The consequences upon a change in control to outstanding options to purchase common stock granted under the 2000 Plan and the 1991 Plan are described under the heading, "Executive Compensation, Compensation of Directors." (2) Amounts reflected are based on the fair market value of our common stock at December 31, 2002 ($1.525), minus the exercise price of the options.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS In June 1996, as a recruiting incentive, we loaned Mr. Woods $200,000, interest-free, in connection with his relocation to San Diego County, California. The note was amended several times by our Board and Human Resources Committee, including an increase the principal amount of the note to $277,500 in July 2000. The $250,000 balance remaining on the loan was repaid in full in 2002. We have entered into employment agreements with Mr. Woods, Dr. Vlasuk and Mr. Keane, which are described under the heading, "Employment Agreements and Change in Control Arrangements." In addition, in March 2002, our Board adopted the Change in Control Plan which provides all of the executive officers with severance benefits upon termination following a change in control of the Company. This plan is also described under the heading, "Employment Agreements and Change in Control Arrangements." In the second half of 1999 we issued and sold, in two private financings, a total of 2,000,000 shares of our common stock for $2.50 per share and 5.5% convertible senior subordinated notes due in August 2006, or the convertible notes, in an aggregate principal amount of $10.0 million. Net proceeds of $14.8 million were raised in these financings. At the option of the note holder, the principal of both notes is convertible into shares of our common stock at $3.25 per share, subject to certain adjustments. Interest on the outstanding principal amounts of these convertible notes accretes at 5.5% per annum, compounded semi-annually, with interest payable upon redemption or conversion. Upon maturity, these notes will have an accreted value of $14.6 million. At our option, the accreted interest portion of both notes may be paid in cash or in our common stock priced at the then-current market price. We have agreed to pay any applicable withholding taxes on behalf of the note holder that may be incurred in connection with the accreted interest, which are estimated and accrued at 30% of the annual accretion. We may redeem the notes any time after August 18, 2002 upon payment of the outstanding principal and accreted interest. We have entered into indemnity agreements with our officers and directors which provide, among other things, that we will indemnify such officer or director, under the circumstances and to the extent provided for therein, for expenses, damages, judgments, fines and settlements such person may be required to pay in actions or proceedings which such person is or may be made a party by reason of their position as a director, officer or other agent of the Company, and otherwise to the full extent permitted under Delaware law and the Company's By-laws. RECENT EVENTS On February 25, 2003, we announced the signing of a definitive merger agreement under which Dendreon Corporation will acquire Corvas, subject to various closing conditions including approval by the stockholders of each company. Under the terms of the agreement, each share of our common stock will be exchanged for a fixed ratio of 0.45 shares of Dendreon common stock in a tax-free reorganization. Upon successful closing of this transaction, our existing stockholders will own approximately 31.4% of the combined company. The transaction is anticipated to close in the second quarter of 2003, subject to approval by stockholders of both companies.
