NOTES TO CONDENSED FINANCIAL STATEMENTS (unaudited) (1) 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 development of new biotherapeutics that address large medical markets, including cardiovascular disease and cancer. (2) Basis of Presentation --------------------- The interim financial information contained herein is unaudited but, in management's opinion, includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation. Following the rules and regulations of the Securities and Exchange Commission (the "SEC"), we have omitted footnote disclosures that would substantially duplicate the disclosures contained in the annual audited financial statements. The condensed financial statements should be read in conjunction with the Company's audited financial statements and notes thereto for the year ended December 31, 2002 included in the Company's Annual Report on Form 10-K. Results for the interim periods are not necessarily indicative of results for other interim periods or for the full year. (3) Restructuring ------------- In July 2002, the Company announced a workforce reduction which resulted in the termination of 42 research and administrative employees. 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. Information related to the restructuring charges is included in the table below (in thousands). Accrued Cash Accrued at Payments at December 31, 2002 Made March 31, 2003 ----------------- ----------------- ----------------- Severance and related $ 277 $ 193 $ 84 Contractual obligations 149 149 -- ------- ------- ------- $ 426 $ 342 $ 84 ======= ======= ======= (4) Net Loss Per Share ------------------ Net loss per share for the three months ended March 31, 2003 and 2002 is computed using the weighted-average number of common shares outstanding. Options totaling 3,609,000 and 3,196,000 shares were excluded from the calculation of diluted net loss per share for the three months ended March 31, 2003 and 2002 respectively. In addition, 3,733,000 and 3,312,000 shares from the assumed conversion of the 5.5% convertible senior subordinated notes issued in 1999 have been excluded from this calculation for the three months ended March 31, 2003 and 2002, respectively. 4 NOTES TO CONDENSED FINANCIAL STATEMENTS, CONTINUED (5) Accounting for Stock-Based Compensation --------------------------------------- The Company accounts for its stock-based plans in accordance with the recognition provisions of APB 25 and related interpretations. Stock compensation expense is recorded on the date of grant only when options are granted to outside consultants in accordance with the provisions of SFAS 123 and the Emerging Issues Task Force consensus Issue 96-18, "Accounting for Equity Instruments that are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services." 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). Three Months Ended March 31, ------------------------------- 2003 2002 -------------- -------------- Net loss - As reported $ (4,625) $ (5,190) Net loss - Pro forma $ (5,377) $ (6,561) Basic and diluted net loss per share - As reported $ (0.17) $ (0.19) Basic and diluted net loss per share - Pro forma $ (0.19) $ (0.24) The per share weighted-average fair market value of options to purchase the Company's common stock granted to employees during the three months ended March 31, 2002 was $4.93, using the Black-Scholes option-pricing model. No options to purchase the Company's common stock were granted to employees during the three months ended March 31, 2003. The per share weighted-average fair market value of options to purchase the Company's common stock granted to members of the board of directors during the three months ended March 31, 2003 and 2002 was $1.33 and $5.06, respectively, on the date of grant. The following weighted-average assumptions were used in calculating compensation cost for stock-based plans under SFAS 123: Three Months Ended March 31, ----------------------------- 2003 2002 ------------- ------------- Expected dividend yield 0% 0% Risk-free interest rate 3.96% 4.18% Expected life 10.00 years 7.27 years Expected volatility 79.50% 81.67% (6) Proposed Merger --------------- On February 24, 2003, the Company executed 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. The transaction is currently anticipated to close in the second quarter of 2003, subject to approval by stockholders of both companies. Upon completion of the proposed merger, the holder of the convertible notes payable 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 following the closing of the proposed merger, then the Company will have an obligation to pay the principal of the notes in cash and the Company 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. 5 NOTES TO CONDENSED FINANCIAL STATEMENTS, CONTINUED (7) Litigation ---------- On March 4, 2003 the Asset Value Fund Limited Partnership ("AVF") filed a purported class action complaint against Corvas and its directors in Delaware state court alleging that the board of directors violated its fiduciary duties when it approved the merger agreement. Specifically, the complaint alleges that (1) the directors failed to consider all available information when deciding to pursue the combination, (2) the directors failed to negotiate a mechanism to protect stockholders from the effects of a decline in Dendreon's common stock price before the combination, and (3) a minority of the directors were furthering their own interests in approving the combination instead of the interests of Corvas' stockholders. AVF is seeking to enjoin Corvas from proceeding with the combination, and also seeks compensatory damages and reimbursement of the costs of bringing suit. Corvas was served with the complaint on March 13, 2003. Corvas denies the allegations in the complaint and intends to defend the action vigorously. Corvas is obligated to advance the costs of defense to its directors, subject to their undertaking to repay the advanced costs under specified circumstances. The insurer has yet not indicated whether it will provide coverage with respect to this claim. On April 10, 2003, AVF filed a books and records action under Section 220 of the Delaware General Corporation Law seeking to inspect Corvas' books and records. Corvas has provided AVF with some documents responsive to its inspection demand, but AVF is seeking additional books and records. To the extent that the purposes AVF stated in its request to review Corvas' books and records are improper or insufficiently stated or AVF seeks documents unrelated to purposes it has properly stated, if any, Corvas will vigorously defend the action. 6 Item 2. 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 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 pro-drugs, that target serine proteases associated with the growth and spread of cancerous tumors. On February 24, 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 currently 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 March 31, 2003, we had an accumulated deficit of $150.8 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. Our research and development costs are comprised of direct costs as well as indirect costs allocated to research and development. Our direct costs include wages, payroll taxes and benefits for our employees engaged in research and development and clinical development activities as well as laboratory supplies, license fees payable to third parties, clinical manufacturing costs, costs incurred for consultants and other outside services, and clinical trial expenses, including patient enrollment fees and amounts paid to the TIMI Group for coordinating the ANTHEM/TIMI-32 trial. Our indirect costs include facility-related costs such as rent, utilities and facilities maintenance, administrative costs associated with our research and development programs and a portion of our general and administrative overhead, each of which is allocated to research and development based upon time expended. 7 RESULTS OF OPERATIONS THREE MONTHS ENDED MARCH 31, 2003 AND 2002 REVENUES. Our operating revenues increased to $38,000 for the three months ended March 31, 2003 from $27,000 in the corresponding period of 2002. Our only source of revenues during these periods was attributable to royalties from license agreements related to sales of recombinant tissue factor, which increased by $11,000 in the quarter ended March 31, 2003 over one year earlier. RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses decreased to $3.2 million, or 64% of our total expenses, in the quarter ended March 31, 2003 compared to $4.7 million, or 79%, in the corresponding quarter of 2002. This $1.5 million decrease was primarily attributable to our July 2002 workforce reduction, which resulted in a realignment of our ongoing preclinical research programs. Our research and development related activities during the quarters ended March 31, 2003 and 2002 related to discovery research in our preclinical cancer programs and our clinical program for rNAPc2, as detailed below: Three Months Ended March 31, --------------------------- 2003 2002 ------------ ------------ Clinical programs: Cardiovascular $ 884 $ 1,282 Indirect costs 444 575 ------------ ------------ Total clinical programs 1,328 1,857 Discovery research 1,835 2,867 ------------ ------------ Total research and development expenses $ 3,163 $ 4,724 ============ ============ We expect that our 2003 research and development expenses will continue to be comprised of costs associated with rNAPc2 development as well as our preclinical cancer research programs. Although we expect to incur costs related to our rNAPc2 Phase II clinical program in UA/NSTEMI patients, we expect our 2003 research and development costs to be lower than those in 2002 as a result of our workforce reduction. As of March 31, 2003, we had paid approximately $2.9 million of costs associated with the first part of this trial and we have not prepaid any significant expenses for subsequent parts of this three-part trial, which we refer to as the ANTHEM/TIMI-32 trial. Since we pay a per patient fee and associated costs for each patient enrolled, we will continue to incur expenses for the first part of this trial until patient enrollment has been completed. We cannot reasonably estimate the timeframe in which the clinical development of rNAPc2 will be completed or the timeframe for advancing any of our preclinical cancer programs into clinical development. 8 GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses for the three months ended March 31, 2003 increased by $500,000 to $1.8 million from $1.3 million in the same quarter of 2002. This increase, primarily due to legal and accounting fees and due diligence associated with our proposed merger with Dendreon, was partially offset by headcount reductions from our July 2002 restructuring. NET OTHER INCOME. Net other income in the first quarter of 2003 was $281,000, compared to $774,000 one year earlier. This $493,000 decrease was attributable to both lower balances available for investment and lower prevailing interest rates. 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 quarter to quarter 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 equity and debt 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 $86.0 million as of March 31, 2003. As of March 31, 2003, our current assets were $70.9 million and our current liabilities were $2.1 million. Working capital, which is our current assets minus our current liabilities, was $68.8 million at March 31, 2003. We invest available cash in accordance with an investment policy set by our board of directors. During the quarter ended March 31, 2003, we used net cash of $3.5 million in our operating activities, all of which was provided by our investing activities. 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 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 at any time 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 we currently expect following the closing of the proposed merger with Dendreon, then we will have an obligation to pay the principal of the notes in cash and we 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. We expect to use our existing cash resources to fund the redemption of the notes. 9 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 equally in the product development costs and any profits from product 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. For at least the next several years, we expect additional operating losses and negative cash flows from operations. As a stand-alone company, we would currently expect our burn rate for 2003 to be in the $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, 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. 10 Our material contractual obligations are as follows (in thousands): Payments Due/Estimated by Period -------------------------------- Less than After 5 1 year 1-3 years 4-5 years years Total (2003) (2004-2006) (2007-2008) (2009 +) ----- ------ ----------- ----------- -------- Commitments(1) - -------------- Operating lease $ 4,987 $ 1,012 $ 3,975 $ -0- $ -0- Capital expenditures (2) 4 4 -0- -0- -0- Committed research and development (3) 19,712 2,998 16,447 178 89 Workforce reduction and related costs 84 84 -0- -0- -0- ------- ------- ------- ------- ------- Total contractual obligations $24,787 $ 4,098 $20,422 $ 178 $ 89 ======= ======= ======= ======= ======= - ------------------ (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 or, in the event we are acquired by Dendreon, paid in cash post-acquisition. This may change for many reasons including, but not limited to, the reasons listed below and in the Risk Factors section. (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 below and in the Risk Factors section. (3) Includes committed costs for rNAPc2, assuming that we complete all three parts of our ANTHEM/TIMI-32 trial, as well as for our preclinical cancer programs. We can elect not to proceed with the ANTHEM/TIMI-32 trial at the end of part one or part two. 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 below and in the Risk Factors section. Our current estimate of our future burn rate, our research and development expenditures 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 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 our success in entering into future collaborative agreements, if any; o the progress on, and scope of, our internally-funded cancer programs including the timing of selection of a clinical drug candidate from our synthetic pro-drug program; o the progress related to our collaboration agreements with Abgenix and Dyax, including the selection of any preclinical candidates; o competing technological and market developments; o the costs we incur in obtaining and enforcing our patents 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 combination with Dendreon, including, but not limited to, proxy solicitation expenses, legal fees and costs associated with the class action complaint filed in Delaware state court. 11 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. CRITICAL ACCOUNTING POLICIES The preparation of our financial statements in accordance with accounting principles generally accepted in the United State 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 included in our Annual Report on Form 10-K. 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 consistent with the completion of research and development objectives in the agreement. Advance payments received in excess of amounts earned are recorded as deferred revenue and recognized as revenue as the research and development objectives of the agreements are met. 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. The milestones specified in our collaborative agreements coincide with the completion of substantive research and development objectives of the agreements. Research grant revenues are recognized as the related research is performed under the terms of the grant. Aside from our license agreements related to sales of recombinant tissue factor from which we recognize modest royalties, we do not currently have any agreements in place under which we expect to recognize revenues in 2003. 12 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 of 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. 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. Item 3. 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. 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 allow us to aggregate their value. The carrying amount of all held to maturity investments as of March 31, 2003 is $77.8 million and they have a weighted-average interest rate of 2.2%. Considering our investment balances as of March 31, 2003, 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. 13 Item 4. CONTROLS AND PROCEDURES EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES Under the supervision and with the participation of our management, including our Chief Executive Officer and Vice President and Controller, we performed an evaluation of the effectiveness of our disclosure controls and procedures within 90 days before the filing date of this quarterly report. Based on that evaluation, our management, including our Chief Executive Officer and Vice President and Controller, concluded that our disclosure controls and procedures are effective. CHANGES IN INTERNAL CONTROLS There have been no significant changes in internal controls or in other factors that could significantly affect internal controls subsequent to the date we completed our evaluation. RISK FACTORS OUR PROPOSED ACQUISITION BY DENDREON CORPORATION MAY NOT BE COMPLETED. 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. Another stockholder has filed a class action lawsuit, seeking to enjoin us from proceeding with the merger. 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 March 31, 2003, we had an accumulated deficit of approximately $150.8 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 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 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, we 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. 15 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 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 rNAPc2 or any other 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; 16 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. 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 comparable as a stand-alone company. Further, 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. 17 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. 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; 18 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 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. 19 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 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, 20 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 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. 21 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 we may incur. Furthermore, coverage is becoming increasingly more 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. 22 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. 23 PART II -- OTHER INFORMATION Item 1. LEGAL PROCEEDINGS 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 when they approved the proposed combination of us and Dendreon Corporation. Specifically, the complaint alleges that (1) the directors failed to consider all available information when deciding to pursue the combination, (2) the directors failed to negotiate a mechanism to protect stockholders from the effects of a decline in Dendreon's stock price before the combination, and (3) a minority of the directors were furthering their own interests in approving the combination instead of the interests of stockholders. AVF is seeking to enjoin us from proceeding with the combination, and also seeks compensatory damages and reimbursement of the costs of bringing suit. We were served with the complaint on March 13, 2003. We deny the allegations in the complaint and intend to defend the action vigorously. We are obligated to advance the costs of defense to our directors, subject to their undertaking to repay the advanced costs under specified circumstances. The insurer has not yet indicated whether it will provide coverage with respect to this claim. On April 10, 2003, AVF filed a books and records action under Section 220 of the Delaware General Corporations Law seeking to inspect our books and records. We have provided AVF with some documents responsive to its inspection demand, but AVF is seeking additional books and records. To the extent that the purposes AVF stated in its request to review our books and records are improper or insufficiently stated or AVF seeks documents unrelated to purposes it has properly stated, if any, we will vigorously defend the action.
