HYBRIDON, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
JUNE 30, 2005
(UNAUDITED)
(1) Organization
     Hybridon, Inc. (the Company) was incorporated in the State of Delaware on May 25, 1989. The Company is engaged in the discovery, development and commercialization of novel therapeutics based on synthetic DNA for the treatment of cancer, asthma/allergies and infectious diseases. Hybridon’s activities are primarily focused on the development of its immune modulatory oligonucleotide, or IMO, technology. Hybridon’s IMO compounds are synthetic DNA-based sequences that are designed to mimic bacterial DNA and be recognized by a specific protein receptor called Toll-like Receptor 9, or TLR9, which triggers the activation and modulation of the immune system. The Company has also been a pioneer in the development of antisense technology, which uses synthetic DNA to block the production of disease causing proteins at the cellular level. Since 2003, Hybridon has devoted substantially all of its research and development efforts to developing its IMO technology and products and expects to continue to focus its research and development efforts in 2005 and in future years on its IMO technology and products. The Company plans to continue to seek to enter into collaborations with third parties for the development and commercialization of products based on its antisense technology.
     Based on its current operating plan, the Company believes that its current cash, cash equivalents, short-term investments and the $4.0 million upfront payment received in July 2005 in connection with the Novartis collaboration will be sufficient to fund operations through mid 2006. The Company’s actual cash requirements will depend on many factors, including particularly the scope and pace of its research and development efforts and its success in entering into strategic alliances.
     The Company does not expect to generate significant additional funds internally until it successfully completes development and obtains marketing approval for products, either alone or in collaborations with third parties, which the Company expects will take a number of years. In addition, it has no committed external sources of funds. As a result, in order for the Company to continue to pursue its clinical and preclinical development programs and continue its operations beyond mid 2006, the Company must raise additional funds from debt, equity financings or from collaborative arrangements with biotechnology or pharmaceutical companies. There can be no assurance that the requisite funds will be available in the necessary time frame or on terms acceptable to the Company. If the Company is unable to raise sufficient funds, the Company may be required to delay, scale back or eliminate some or all of its operating plans and possibly relinquish rights to portions of the Company’s technology or products. In addition, increases in expenses or delays in clinical development may adversely impact the Company’s cash position and require further cost reductions. No assurance can be given that the Company will be able to operate profitably on a consistent basis, or at all, in the future.
(2) Unaudited Interim Financial Statements
     The accompanying unaudited consolidated condensed financial statements included herein have been prepared by the Company in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of interim period results have been included. The Company believes that its disclosures are adequate to make the information presented not misleading. Interim results for the three and six-month periods ended June 30, 2005 are not necessarily indicative of results that may be expected for the year ended December 31, 2005. For

further information, refer to the financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2004, which was filed with the Securities and Exchange Commission on March 25, 2005.
(3) Net Loss per Common Share
     The following table sets forth the computation of basic and diluted loss per share:
                                 
    Three Months Ended June 30,   Six Months Ended June 30,
    2005   2004   2005   2004
Numerator:
                               
Net loss
  $ (3,653,085 )   $ (3,170,747 )   $ (6,875,428 )   $ (5,903,641 )
Accretion of preferred stock dividends
    (164 )     (158 )     (328 )     (2,675,677 )
 
                               
Numerator for basic and diluted loss per share applicable to common shareholders
  $ (3,653,249 )   $ (3,170,905 )   $ (6,875,756 )   $ (8,579,318 )
 
                               
 
                               
Denominator for basic and diluted loss per share
    111,044,873       98,269,236       111,006,164       89,620,691  
 
                               
Loss per share — basic and diluted:
                               
Net loss per share
  $ (0.03 )   $ (0.03 )   $ (0.06 )   $ (0.07 )
Accretion of preferred stock dividends
    (0.00 )     (0.00 )     (0.00 )     (0.03 )
 
                               
Net loss per share applicable to common stockholders
  $ (0.03 )   $ (0.03 )   $ (0.06 )   $ (0.10 )
 
                               
     Basic net loss per common share is computed using the weighted average number of shares of common stock outstanding during the period. For the three and six months ended June 30, 2005 and 2004, diluted net loss per share of common stock is the same as basic net loss per share of common stock, as the effects of the Company’s common stock equivalents are antidilutive. Total antidilutive securities were 39,373,895 and 27,972,186 at June 30, 2005 and 2004, respectively. These antidilutive securities, including stock options, warrants, convertible preferred stock and convertible debt instruments are not included in the Company’s calculation of diluted net loss per common share.
(4) Cash Equivalents and Investments
     The Company considers all highly liquid investments with maturities of 90 days or less when purchased to be cash equivalents. Cash and cash equivalents at June 30, 2005 and December 31, 2004 consisted of cash and money market funds.
     The Company accounts for investments in accordance with Statement of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt and Equity Securities. Management determines the appropriate classification of marketable securities at the time of purchase. In accordance with SFAS No. 115, investments that the Company does not have the positive intent to hold to maturity are classified as “available-for-sale” and reported at fair market value. Unrealized gains and losses associated with “available-for-sale” investments are recorded in “Accumulated other comprehensive loss” on the accompanying consolidated balance sheet. The amortization of premiums and accretion of discounts, and any realized gains and losses and declines in value judged to be other than temporary, and interest and dividends are included in “Investment income, net” on the accompanying consolidated statement of operations for all available-for-sale securities. The Company had no “held-to-maturity” investments, as defined by SFAS No. 115, at June 30, 2005 and December 31, 2004. The cost of securities sold is based on the specific identification method. The Company had no realized gains or losses on its investments for the three and six months ended June 30, 2005 and 2004, respectively. There were no losses or permanent declines in value included in “investment income” for any securities in the three and six months ended June 30, 2005 and 2004.
     The Company had no long-term investments as of June 30, 2005 and December 31, 2004. Available-for-sale securities are classified as short-term regardless of their maturity date if the Company has them available to fund

operations within one year of the balance sheet date. Auction securities are highly liquid securities that have floating interest or dividend rates that reset periodically through an auctioning process that sets rates based on bids. Issuers include municipalities, closed-end bond funds and corporations. These securities can either be debt or preferred shares. The Company’s short-term investments consisted of the following at June 30, 2005 and December 31, 2004:
                 
    June 30,   December 31,
    2005   2004
Short-term available-for-sale investments at market value:
               
Corporate bonds

Government bonds
    1,997,820       2,986,990

    5,400,000       4,400,000  
 
               
Total
  $ 7,397,820     $ 9,391,140  
 
               
(5) Property and Equipment
     At June 30, 2005 and December 31, 2004, net property and equipment at cost consists of the following:
                 
    June 30,   December 31,
    2005   2004
Leasehold improvements
  $ 424,500     $ 424,500  
Laboratory equipment and other
    1,706,590       1,804,799  
 
               
Total property and equipment, at cost
    2,131,090       2,229,299  
Less: Accumulated depreciation and amortization
    1,842,050       1,877,508  
 
               
Property and equipment, net
  $ 289,040     $ 351,791  
 
               
     In the first quarter of 2005, the Company wrote off unused property and equipment that had a cost of approximately $109,000 resulting in a loss of approximately $2,000.
(6) Stock-Based Compensation Related to Repriced Options
     In September 1999, the Company’s Board of Directors authorized the repricing of options to purchase 5,251,827 shares of common stock to an exercise price of $0.50 per share, which represented the market value of the common stock on the date of the repricing. These options are subject to variable plan accounting which requires the Company to remeasure the intrinsic value of the repriced options, through the earlier of the date of exercise, cancellation or expiration, at each reporting date. For the three months ended June 30, 2005 and 2004, the Company recognized a credit of approximately $56,000 and $257,000, respectively, as stock compensation relating to these repriced options as a result of a decrease in the intrinsic value of these options between March 31, 2005 and June 30, 2005 and March 31, 2004 and June 30, 2004, respectively. For the six months ended June 30, 2005, the Company recognized approximately $28,000 as stock compensation expense relating to these repriced options as a result of an increase in the intrinsic value of these options between December 31, 2004 and June 30, 2005. For the six months ended June 30, 2004, the Company recognized a credit of approximately $574,000 for stock compensation from repriced options as a result of a decrease in the intrinsic value of these options between December 31, 2003 and June 30, 2004. As of June 30, 2005 and 2004, options to purchase 2,108,802 and 2,406,546 shares, respectively, remained subject to variable plan accounting.
(7) Series A Convertible Preferred Stock
     On December 4, 2003, the Company’s stockholders approved amendments to the Company’s Restated Certificate of Incorporation that:
    reduced the liquidation preference of the Company’s Series A convertible preferred stock from $100 per share to $1 per share;
 
    reduced the annual dividend on the Company’s Series A convertible preferred stock from 6.5% to 1%; and

    increased the number of shares of the Company’s common stock issuable upon conversion of the Company’s Series A convertible preferred stock by 25% over the number of shares that would otherwise be issuable for a 60-day conversion period between December 4, 2003 and February 2, 2004 inclusive.
     During the 60-day conversion period, the conversion ratio was increased so that the Series A convertible preferred stockholders could receive approximately 29.41 shares of common stock for each share of Series A convertible preferred stock converted instead of the stated conversion rate of 23.53 shares. The value of the additional shares issued during the 60-day conversion period was recorded as an addition to dividends in the statement of operations at the time of conversion. For the six months ended June 30, 2004 the Company recorded $3.2 million of preferred stock dividends related to the additional shares issued in 2004.
     From January 1, 2004 through June 30, 2004, 488,570 shares of Series A convertible preferred stock were converted into 14,369,740 shares of the Company’s common stock at the adjusted conversion ratio. As a result of these conversions, $570,000 of dividends accreted during the year ended December 31, 2003 were reversed during the six month period ended June 30, 2004 because the former holders of these shares of Series A convertible preferred stock were no longer entitled to such dividends once their shares of series A convertible preferred stock were converted into common stock.
(8) Stock-Based Compensation
     The Company applies the disclosure-only provisions of SFAS No. 123, Accounting for Stock-Based Compensation. The Company continues to account for employee stock compensation at intrinsic value, in accordance with Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees and related interpretations, with disclosure of the effects of fair value accounting on net income or net loss and related per share amounts on a pro forma basis.
     The pro forma effect of applying SFAS No. 123 for the three and six months ended June 30, 2005 and 2004 would be as follows:
                                 
    Three months ended June 30,   Six months ended June 30,

(11) Notes Payable
     On May 24, 2005, Hybridon sold approximately $5.0 million in principal amount of 4% convertible subordinated notes due April 30, 2008 (the 4% Notes). The Company has agreed to pay interest on the 4% Notes in arrears on December 15, 2005 for the period from the issuance to that date, and thereafter semi-annually in arrears on April 30 and October 30 and at maturity or conversion. The Company has the option to pay interest on the 4% Notes in cash or in shares of the Company’s common stock at the then current market value of the Company’s common stock. Holders of the 4% Notes may convert, at any time prior to maturity, the principal amount of the 4% Notes (or any portion thereof) into shares of the Company’s common stock at a conversion price of $0.89 per share. The Company may cause the principal amount of the 4% Notes to be converted into shares of the Company’s common stock at the then current conversion price at any time prior to May 24, 2006 if the volume weighted average of the closing sales prices of the Company’s common stock for 10 consecutive trading days is equal to at least $1.78 per share or at any time on or after May 24, 2006 if the volume weighted average of the closing sales prices of the Company’s common stock for 10 consecutive trading days is equal to at least $1.12 per share. If the Company conducts a financing resulting in greater than $10.0 million in gross proceeds, the Company may elect to convert the 4% Notes into shares of the Company’s common stock at the then current conversion price if the purchase price paid by the new investors in the financing (on a common stock equivalent basis) is greater than the then current conversion price of the 4% Notes. Holders of the 4% Notes may demand that the Company redeem the 4% Notes upon a change in control, a merger with an independent company, or a change in the Company’s listing status.
     The Company capitalized its financing costs associated with the sale of the 4% Notes and is amortizing them over the term of the 4% Notes. These costs include the Black-Scholes value of the warrants, legal expenses and miscellaneous costs related to the placement agent.
     On April 1, 2004, the Company’s 9% convertible subordinated notes matured. As a result, the Company paid $1,306,000 to the note holders in payment of the principal amount outstanding under the notes plus accrued interest through the maturity date of $58,770.

(12) Financing
     In April 2004, the Company raised approximately $11.8 million in gross proceeds through a registered direct offering. In the offering, the Company sold 16,899,800 shares of common stock and warrants to purchase 3,041,964 shares of common stock to institutional and other investors. The warrants to purchase common stock have an exercise price of $1.14 per share and are exercisable at any time on or after October 21, 2004 and on or prior to April 20, 2009. The warrants may be exercised by cash payment only. On or after October 21, 2005, the Company may redeem the warrants if the closing sales price of the common stock for each day of any 20 consecutive trading day period ending within 30 days prior to providing notice of redemption is greater than or equal to $2.60 per share. The redemption price will be $0.01 per share of common stock underlying the warrants. The Company may exercise its right to redeem the warrants by providing 30 days prior written notice to the holders of the warrants. The net proceeds to the Company from the offering, excluding the proceeds of any future exercise of the warrants, totaled approximately $10.7 million.
(13) Option Awards
     On May 12, 2005, Hybridon’s Compensation Committee of the Board of Directors approved a grant of 1,000,000 stock options to the Company’s Chief Executive Office. These options vest quarterly over a three-year period. In addition, on May 12, 2005, the Compensation Committee agreed to grant additional stock options to the CEO to purchase an aggregate of 1,000,000 shares of the Company’s common stock upon the achievement of specified milestones. Any options granted as a result of the achievement of these milestones will vest over a three-year period commencing on the date the specified milestone was achieved. On June 1, 2005, 400,000 of these options were granted resulting in a charge to deferred compensation of $72,000, which represents the difference between the option exercise price and the market price on the date that the milestone was achieved. The exercise price of the remaining 600,000 options, if granted, will be set at the current market price on the date of grant.
(14) Novartis Collaboration
     On May 31, 2005, the Company entered into a research collaboration and option agreement and a license, development and commercialization agreement with Novartis International Pharmaceutical Ltd. to discover, develop and potentially commercialize immune-modulatory oligonucleotides that are toll-like receptor 9 agonists and that are identified as potential treatments for human allergy and respiratory diseases. In addition, beginning on May 31, 2007, if specified conditions are satisfied, Novartis may expand the collaboration to include additional human disease areas, other than oncology and infectious diseases. Under the terms of the agreements, Novartis paid the Company a $4.0 million license fee in July 2005 and agreed to fund substantially all research activities. If Novartis elects to exercise its option to develop and commercialize licensed IMOs in the initial collaboration disease areas, Novartis is potentially obligated to pay the Company up to $132.0 million based on the achievement of clinical development, regulatory approval and cumulative net sales milestones. Novartis is also obligated to make royalty payments based on annual net sales of the product(s) commercialized under the agreement.
     As of June 30, 2005, the $4.0 million upfront payment was recorded on the Company’s balance sheet in accounts receivable and deferred revenue. The Company is recognizing the $4.0 million upfront payment as revenue over the two-year term of the research collaboration.
(15) New Accounting Pronouncement
     In December 2004, the FASB issued SFAS No. 123 (revised 2004), “Share-Based Payment”, which is a revision of SFAS No. 123, “Accounting for Stock-Based Compensation”. SFAS No. 123(R) supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees”, and amends SFAS No. 95, “Statement of Cash Flows”. Generally, the approach in SFAS No. 123(R) is similar to the approach described in SFAS No. 123. However, SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Pro forma disclosure is no longer an alternative. The new standard will be effective for the Company in the quarter beginning January 1, 2006.

Table of Contents

     As permitted by SFAS 123, the Company currently accounts for share-based payments to employees using APB 25’s intrinsic value method and, as such, generally, except for marking to market the repriced options discussed in Note 6, the Company recognizes no compensation cost for employee stock options. Accordingly, the adoption of SFAS 123(R)’s fair value method may have a material impact on the Company’s results of operations, although it will have no impact on the Company’s overall financial position. The impact of adopting SFAS 123(R) cannot be predicted at this time because it will depend on levels of share-based payments granted in the future. However, had the company adopted SFAS 123(R) in a prior period, the impact of applying that standard would have approximated the impact of SFAS 123 as described in the disclosure of pro forma net loss and net loss per share in Note 8 to these financial statements. The Company is currently evaluating the impact of adopting of SFAS 123(R) on its financial position and results of operations, including the valuation methods and support for the assumptions that underlie the valuation of the awards.
ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
GENERAL
     We are engaged in the discovery, development and commercialization of novel therapeutics based on synthetic DNA for the treatment of cancer, asthma/allergies and infectious diseases. Our activities are primarily focused on the development of our immune modulatory oligonucleotide, or IMO, technology. Our IMO compounds are synthetic DNA-based sequences that are designed to mimic bacterial DNA and be recognized by a specific protein receptor called Toll-like Receptor 9, or TLR9, which triggers the activation and modulation of the immune system. We also have been a pioneer in the development of antisense technology, which uses synthetic DNA to block the production of disease causing proteins at the cellular level. Since 2003, we have devoted substantially all of our research and development efforts to our IMO technology and products and expect to continue to focus our research and development efforts in 2005 and in future years on our IMO technology and products. We plan to continue to seek to enter into collaborations with third parties for the development and commercialization of products based on our antisense technology.
     We have incurred total losses of $306.2 million through June 30, 2005 and expect to incur substantial operating losses in the future. In order to commercialize our therapeutic products, we need to address a number of technological challenges and to comply with comprehensive regulatory requirements.
APPLICATION OF CRITICAL ACCOUNTING POLICIES
     This management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments, including those related to revenue recognition. Management bases its estimates and judgments on historical experience and on various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
     We regard an accounting estimate or assumption underlying our financial statements as a “critical accounting estimate” where (i) the nature of the estimate or assumption is material due to the level of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change; and (ii) the impact of the estimates and assumptions on financial condition or operating performance is material.

Table of Contents

     Our significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2004. Not all of these significant accounting policies, however, fit the definition of “critical accounting estimates.” We believe that our accounting policies relating to revenue recognition, as described under the caption “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” in our Annual Report on Form 10-K for the year ended December 31, 2004, fit the definition of “critical accounting estimates and judgments.”
RESULTS OF OPERATIONS
Three and Six Months Ended June 30, 2005 and 2004
Alliance Revenues
     Total alliance revenue increased by $223,000, or 253%, from $88,000 for the three months ended June 30, 2004 to $311,000 for the three months ended June 30, 2005 and decreased by $250,000, or 34%, from $733,000 for the six-months ended June 30, 2004 to $483,000 for the six months ended June 30, 2005. Alliance revenue consists of revenue we receive under our collaboration and licensing agreements and includes research and development payments, milestone payments, license fees, sublicense fees, and royalty payments. The increase in revenue in the second quarter of 2005 reflects the portion of the $4.0 million upfront fee under the Novartis agreement recognized during the period and related research and development revenue associated with the agreement. The decrease in the first half of 2005 as compared to the first half of 2004 primarily reflects research and development revenue in the first half of 2004 associated with supplying a collaborator with drug product for clinical trials during the first quarter of 2004 and the achievement of a milestone for which milestone fees were earned in the first quarter of 2004.
     Research and Development Expenses
     Research and development expenses increased by $511,000, or 20%, from $2,541,000 for the three months ended June 30, 2004 to $3,052,000 for the three months ended June 30, 2005 and increased by $305,000, or 6%, from $5,346,000 for the six months ended June 30, 2004 to $5,651,000 for the six months ended June 30, 2005. The increase for the three and six months ended June 30, 2005 primarily reflects the manufacturing costs for the production of clinical drug supply being utilized in our ongoing phase 2 study of IMOxine for the treatment of renal cell carcinoma and other future trials. The increase in the six-month period ended June 30, 2005 is also attributable to our purchase of raw materials in the first quarter of 2005 in anticipation of the production of clinical drug supplies completed in the second quarter of 2005. The increase in costs in the six-month period was partially offset by increased costs in the 2004 period incurred in connection with the cost of supplying a collaboration partner with drug product for clinical trials during the first quarter of 2004. Our other research and development costs in both periods relate primarily to the cost of advancing our basic IMO research program and developing our IMO technology. These costs include salaries, allocated overhead, general lab supplies and patent preparation costs and related filing fees.
     Our lead drug candidate in our IMO program is HYB2055. We are developing HYB2055 for oncology applications under the name IMOxine. In connection with developing HYB2055, we incurred approximately $1.3 million and $0.7 million in direct external expenses in the three months ended June 30, 2005 and 2004, respectively, and we incurred approximately $2.0 million and $1.3 million in direct external expenses in the six months ended June 30, 2005 and 2004, respectively. These expenses include payments to independent contractors and vendors for preclinical studies and drug manufacturing and related costs but exclude internal costs such as payroll and overhead. In October 2004, we commenced patient recruitment for an open label, multi-center phase 2 clinical trial of IMOxine as a monotherapy in patients with metastatic or recurrent clear cell renal carcinoma. We plan to recruit a minimum of 46 patients into the first stage of the trial. We are also conducting a phase 1 clinical trial of IMOxine in patients with refractory solid tumor cancers, which is being conducted at the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center in Washington, D.C. Except for one patient who has received IMOxine treatment in the trial for over eighteen months, treatment under the protocol was completed in June 2004 and results were presented at the American Society of Clinical Oncology annual meeting in May 2005. Weekly IMOxine treatment was well tolerated by advanced cancer patients.

Table of Contents

     Because these projects are in the early stage of development and given the technological and regulatory hurdles likely to be encountered in the development and commercialization of our products, the future timing and costs of our various research and development programs are uncertain.
     General and Administrative Expenses
     General and administrative expenses decreased by $11,000, or 1%, from $1,025,000 in the three months ended June 30, 2004 to $1,014,000 in the three months ended June 30, 2005 and decreased by $130,000, or 7%, from $1,922,000 in the six months ended June 30, 2004 to $1,792,000 in the six months ended June 30, 2005. The decrease for the three and six month periods is primarily the result of lower compensation costs. The decrease in the three- and six-month periods was partially offset by higher corporate legal expenses associated with our Novartis agreement in the three months ended June 30, 2005. The decrease in the six month period is also attributable to lower insurance expenses in the first quarter of 2005.
     Stock-Based Compensation
     As a result of repricing of our stock options in September 1999, some of our outstanding stock options are subject to variable plan accounting which requires us to measure the intrinsic value of the repriced options through the earlier of the date of exercise, cancellation or expiration at each reporting date. Operating results include a credit of approximately $56,000 and $257,000 for the three months ended June 30, 2005 and 2004, respectively, as a result of a decrease in the intrinsic value of these repriced options from March 31 to June 30 of each year. We recorded approximately $28,000 of expense for the six months ended June 30 ,2005 from these repriced options as a result of an increase in the intrinsic value of these options between December 31, 2004 and June 30, 2005. For the six months ended June 30, 2004, we recorded a credit of approximately $574,000 to stock compensation as a result of a decrease in the intrinsic value of these repriced options from December 31, 2003 to June 30, 2004. Compensation charges and credits will likely occur in the future based upon changes in the market value of our common stock.
     Investment Income, net
     Investment income increased by approximately $33,000, or 66%, from $50,000 in the three months ended June 30, 2004 to $83,000 in the three months ended June 30, 2005 and increased by approximately $64,000, or 74%, from $86,000 in the six months ended June 30, 2004 to $150,000 in the six months ended June 30, 2005. The change for the three and six months ended June 30, 2005 was primarily a result of higher interest rates.
     Interest Expense
     Interest expense in the three and six months ended June 30, 2005 consisted of interest on our 4% notes secured in May 2005 and amortization of deferred financing costs associated with these notes. Our interest expense for the six months ended June 30, 2004 consisted of interest on our 9% notes. On April 1, 2004, upon the maturity of our 9% notes, we paid $1,306,000 representing the outstanding principal amount of our 9% notes, plus accrued interest. As a result, we had no interest expense for the three months ended June 30, 2004.
     Preferred Stock Dividends
     Dividends on the remaining 655 shares of Series A preferred stock outstanding are accreted at an annual rate of 1%. Accretion of preferred stock dividends decreased by approximately $2,676,000, or 100%, from $2,676,000 for the six months ended June 30, 2004 to nearly zero for the six months ended June 30, 2005. The decrease for the six-month period was primarily attributable to the conversions of Series A convertible preferred stock into common stock in the fourth quarter of 2003 and the first quarter of 2004. The conversion took place in accordance with an amendment to our Restated Certificate of Incorporation approved by our stockholders on December 4, 2003 that increased the number of shares of our common stock issuable upon conversion of our series A convertible preferred stock by 25% over the number of shares that would otherwise have been issuable upon conversion during a 60-day conversion period. The value of the additional shares issued during the 60-day conversion period was recorded as an

14


Table of Contents

addition to dividends in the statement of operations at the time of conversion. The value of the additional dividend amounted to $3,245,000 during the first six months of 2004 and was partially offset by a reversal of $570,000 of dividends accreted during the year ended December 31, 2003 with respect to these shares that was reversed during the six month period ended June 30, 2004 because the former holders of these shares of Series A convertible preferred stock were no longer entitled to such dividends once their shares of series A convertible preferred stock were converted into common stock.
Net Loss Applicable to Common Stockholders
     As a result of the factors discussed above, our net loss applicable to common stockholders amounted to approximately $3,653,000 and $3,171,000 for the three months ended June 30, 2005 and 2004, respectively and to approximately $6,876,000 and $8,579,000 for the six months ended June 30, 2005 and 2004, respectively.
LIQUIDITY AND CAPITAL RESOURCES
Sources of Liquidity
     We require cash to fund our operating expenses, to make capital expenditures and to pay debt service. We have funded our cash requirements primarily through equity and debt financing, license fees and research funding under collaborative and license agreements.
Cash Flows
     As of June 30, 2005, we had approximately $11,429,000 in cash, cash equivalents and short-term investments, a decrease of approximately $2,984,000 from December 31, 2004.
     We used $7,685,000 of cash for operating activities during the six months ended June 30, 2005, principally to fund our research and development expenses and our general and administrative expenses. The $7,685,000 primarily consists of our net loss of $6,875,000 for the period, as adjusted for the increase in our accounts receivable and prepaid expenses reflecting the upfront license fee and research and development payments due us under our collaboration agreement with Novartis and annual insurance premiums paid at the beginning of the year, respectively, and for the decrease in our accrued expenses reflecting charges for raw materials paid in the second quarter for future manufacturing of our drug products and the continued payments due under our former CEO’s severance agreement.
     Net cash provided by investing activities reflects the proceeds of $4,000,000 that we received from the sale and maturity of “available-for-sale” securities offset by the purchase of $2,000,000 in “available-for-sale” securities in the six months ended June 30, 2005.
     Net cash provided by financing activities reflects the approximately $5,033,000 we received from the issuance of our 4% notes offset by the expenses associated with their issuance in the six months ended June 30, 2005.
Funding Requirements
     Based on our current operating plan, we believe that our existing cash, cash equivalents, short-term investments and the $4.0 million upfront payment received in July 2005 in connection with the Novartis collaboration will be sufficient to fund operations through mid 2006. Our actual cash requirements will depend on many factors, including particularly the scope and pace of our research and development efforts and our success in entering into strategic alliances.
     In May 2005, we issued approximately $5.0 million in principal amount of 4% convertible subordinated notes due April 30, 2008. Interest on the 4% convertible subordinated notes is payable in arrears on December 15, 2005 for the period from issuance to that date, and thereafter semi-annually on April 30 and October 30 and at maturity or

conversion. We have the option to pay interest on the 4% convertible subordinated notes in cash or in shares of common stock at the then current market value of the common stock.
     We do not expect to generate significant additional funds internally until we successfully complete development and obtain marketing approval for products, either alone or in collaboration with third parties, which we expect will take a number of years. In addition, we have no committed external sources of funds. As a result, in order for us to continue to pursue our clinical and preclinical development programs and continue operations beyond mid 2006, we will need to raise additional funds from debt, equity financings or from collaborative arrangements with biotechnology or pharmaceutical companies. There can be no assurance that the requisite funds will be available in the necessary time frame or on terms acceptable to us. Should we be unable to raise sufficient funds, we may be required to significantly curtail our operating plans and possibly relinquish rights to portions of our technology or products. In addition, increases in expenses or delays in clinical development may adversely impact our cash position and require further cost reductions. No assurance can be given that we will be able to operate profitably on a consistent basis, or at all, in the future. We believe that the key factors that will affect our internal and external sources of cash are:
  the success of our clinical and preclinical development programs;
 
  the receptivity of the capital markets to financings by biotechnology companies; and
 
  our ability to enter into strategic collaborations with biotechnology and pharmaceutical companies and the success of such collaborations.
Contractual Obligations
     We have contractual obligations in the form of employment agreements, operating leases and consulting and collaboration agreements. Our contractual obligations as of December 31, 2004 were set forth under the caption “Contractual Obligations” in our Annual Report on Form 10-K for the year ended December 31, 2004.
     In May 2005, we issued approximately $5.0 million in principal amount of 4% convertible subordinated notes. On April 30, 2008 the entire principal amount of 4% convertible subordinated notes will become due and payable.

RISK FACTORS
Investing in our common stock involves a high degree of risk, and you should carefully consider the risks and uncertainties described below in addition to the other information included or incorporated by reference in this quarterly report. If any of the following risks actually occurs, our business, financial condition or results of operations would likely suffer, possibly materially. In that case, the trading price of our common stock could fall.
Risks Relating to Our Financial Results and Need for Financing
We have incurred substantial losses and expect to continue to incur losses. We will not be successful unless we reverse this trend.
     We have incurred losses in every year since our inception, except for 2002 when our recognition of revenues under a license and collaboration agreement resulted in us reporting net income for that year. As of June 30, 2005, we had incurred operating losses of approximately $306.2 million. We expect to continue to incur substantial operating losses in future periods. These losses, among other things, have had and will continue to have an adverse effect on our stockholders’ equity, total assets and working capital.
     We have received no revenues from the sale of drugs. To date, almost all of our revenues have been from collaborative and license agreements. We have devoted substantially all of our efforts to research and development, including clinical trials, and we have not completed development of any drugs. Because of the numerous risks and uncertainties associated with developing drugs, we are unable to predict the extent of any future losses, whether or when any of our products will become commercially available, or when we will become profitable, if at all.
We will need additional financing, which may be difficult to obtain. Our failure to obtain necessary financing or doing so on unattractive terms could adversely affect our discovery and development programs and other operations.
We will require substantial funds to conduct research and development, including preclinical testing and clinical trials of our drugs. We will also require substantial funds to conduct regulatory activities and to establish commercial manufacturing, marketing and sales capabilities. We believe that, based on our current operating plan, our existing cash, cash equivalents, short-term investments, and the $4.0 million upfront payment that we received in July 2005 in connection with the Novartis collaboration, will be sufficient to fund our operations through mid 2006. However, we could reduce planned activities if we need to conserve such funds.
We will need to raise additional funds to operate our business beyond such time. We believe that the key factors that will affect our ability to obtain additional funding are:
    the success of our clinical and preclinical development programs;
 
    the receptivity of the capital markets to financings by biotechnology companies; and
 
    our ability to enter into strategic collaborations with biotechnology and pharmaceutical companies and the success of such collaborations.
     Additional financing may not be available to us when we need it or may not be available to us on favorable terms. We could be required to seek funds through arrangements with collaborators or others that may require us to relinquish rights to some of our technologies, drug candidates or drugs which we would otherwise pursue on our own. In addition, if we raise additional funds by issuing equity securities, our then existing stockholders will experience dilution. The terms of any financing may adversely affect the holdings or the rights of existing stockholders. If we are unable to obtain adequate funding on a timely basis or at all, we may be required to significantly curtail one or more of our discovery or development programs. For example, we significantly curtailed expenditures on our research and development programs during 1999 and 2000 because we did not have sufficient funds available to advance these programs at planned levels.

Risks Relating to Our Business, Strategy and Industry
We are depending heavily on the success of our lead drug candidate, IMOxine, which is in clinical development. If we are unable to commercialize this product, or experience significant delays in doing so, our business will be materially harmed.
     We are investing a significant portion of our time and financial resources in the development of our lead drug candidate, IMOxine. We anticipate that our ability to generate product revenues will depend heavily on the successful development and commercialization of this product. The commercial success of this product will depend on several factors, including the following:
    successful completion of clinical trials;
 
    receipt of marketing approvals from the FDA and equivalent foreign regulatory authorities;
 
    establishing commercial manufacturing arrangements with third party manufacturers;
 
    launching commercial sales of the product, whether alone or in collaboration with others; and
 
    acceptance of the product in the medical community and with third party payors.
Our efforts to commercialize this product are at an early stage, as we are currently conducting a phase 2 clinical trial in patients with metastatic or recurrent clear cell renal carcinoma. If we are not successful in commercializing this product, or are significantly delayed in doing so, our business will be materially harmed.
If our clinical trials are unsuccessful, or if they are significantly delayed, we may not be able to develop and commercialize our products.
     We may not be able to successfully complete any clinical trial of a potential product within any specified time period. In some cases, we may not be able to complete the trial at all. Moreover, clinical trials may not show our potential products to be both safe and efficacious. Thus, the FDA and other regulatory authorities may not approve any of our potential products for any indication.
     In order to obtain regulatory approvals for the commercial sale of our products, we will be required to complete extensive clinical trials in humans to demonstrate the safety and efficacy of our drug candidates. We may not be able to obtain authority from the FDA or other equivalent foreign regulatory agencies to complete these trials or commence and complete any other clinical trials.
     The results from preclinical testing of a drug candidate that is under development may not be predictive of results that will be obtained in human clinical trials. In addition, the results of early human clinical trials may not be predictive of results that will be obtained in larger scale, advanced stage clinical trials. A failure of one or more of our clinical trials can occur at any stage of testing. Further, there is to date little data on the long-term clinical safety of our lead compounds under conditions of prolonged use in humans, nor on any long-term consequences subsequent to human use. We may experience numerous unforeseen events during, or as a result of, preclinical testing and the clinical trial process that could delay or inhibit our ability to receive regulatory approval or commercialize our products, including:
    regulators or institutional review boards may not authorize us to commence a clinical trial or conduct a clinical trial at a prospective trial site;
 
    our preclinical tests or clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional preclinical testing or clinical trials or we may abandon projects that we expect may not be promising;

18


Table of Contents

    we might have to suspend or terminate our clinical trials if the participating patients are being exposed to unacceptable health risks;
 
    regulators or institutional review boards may require that we hold, suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements;
 
    the cost of our clinical trials may be greater than we currently anticipate; and
 
    the effects of our products may not be the desired effects or may include undesirable side effects or the products may have other unexpected characteristics.
     As an example, in 1997, after reviewing the results from the clinical trial of GEM91, a 1st generation antisense compound and our lead drug candidate at the time, we determined not to continue the development of GEM91 and suspended clinical trials of this product candidate.
     The rate of completion of clinical trials is dependent in part upon the rate of enrollment of patients. The rate of enrollment in our ongoing phase 2 clinical trial of IMOxine has thus far been slower than anticipated and may delay the completion of trial beyond the time we expected. Patient accrual is a function of many factors, including:
    the size of the patient population,
 
    the proximity of patients to clinical sites,
 
    the eligibility criteria for the study,
 
    the nature of the study,
 
    the existence of competitive clinical trials and
 
    the availability of alternative treatments.
Our product development costs will increase if we experience delays in our clinical trials. We do not know whether planned clinical trials will begin as planned, will need to be restructured or will be completed on schedule, if at all. Significant clinical trial delays also could allow our competitors to bring products to market before we do and impair our ability to commercialize our products.
We face substantial competition which may result in others discovering, developing or commercializing drugs before or more successfully than us.
     The biotechnology industry is highly competitive and characterized by rapid and significant technological change. We face, and will continue to face, intense competition from organizations such as pharmaceutical and biotechnology companies, as well as academic and research institutions and government agencies. Some of these organizations are pursuing products based on technologies similar to our technologies. Other of these organizations have developed and are marketing products, or are pursuing other technological approaches designed to produce products, that are competitive with our product candidates in the therapeutic effect these competitive products have on diseases targeted by our product candidates. Our competitors may discover, develop or commercialize products or other novel technologies that are more effective, safer or less costly than any that we are developing. Our competitors may also obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours.
     Many of our competitors are substantially larger than we are and have greater capital resources, research and development staffs and facilities than we have. In addition, many of our competitors are more experienced than we

19


Table of Contents

are in drug discovery, development and commercialization, obtaining regulatory approvals and drug manufacturing and marketing.
     We anticipate that the competition with our products and technologies will be based on a number of factors including product efficacy, safety, availability and price. The timing of market introduction of our products and competitive products will also affect competition among products. We expect the relative speed with which we can develop products, complete the clinical trials and approval processes and supply commercial quantities of the products to the market to be important competitive factors. Our competitive position will also depend upon our ability to attract and retain qualified personnel, to obtain patent protection or otherwise develop proprietary products or processes and to secure sufficient capital resources for the period between technological conception and commercial sales.
Because the products that we may develop will be based on new technologies and therapeutic approaches, the market may not be receptive to these products upon their introduction.
     The commercial success of any of our products for which we may obtain marketing approval from the FDA or other regulatory authorities will depend upon their acceptance by the medical community and third party payors as clinically useful, cost-effective and safe. Many of the products that we are developing are based upon technologies or therapeutic approaches that are relatively new and unproven. The FDA has only granted marketing approval for one product based on antisense technology which is currently being marketed by another company for the treatment of cytomegalovirus retinitis, an infectious disease, in patients with AIDs. The FDA has not granted marketing approval to any products based on IMO technology and no such products are currently being marketed. As a result, it may be more difficult for us to achieve regulatory approval or market acceptance of our products. Our efforts to educate the medical community on these potentially unique approaches may require greater resources than would be typically required for products based on conventional technologies or therapeutic approaches. The safety, efficacy, convenience and cost-effectiveness of our products as compared to competitive products will also affect market acceptance.
Competition for technical and management personnel is intense in our industry, and we may not be able to sustain our operations or grow if we are unable to attract and retain key personnel.
     Our success is highly dependent on the retention of principal members of our technical and management staff, including Sudhir Agrawal. Dr. Agrawal serves as our President, Chief Scientific Officer and Chief Executive Officer. Dr. Agrawal has extensive experience in the pharmaceutical industry, has made significant contributions to the field of nucleic acid chemistry and is named as an inventor on over 200 patents and patent applications worldwide. Dr. Agrawal provides the scientific leadership for our research and development activities and directly supervises our research staff. The loss of Dr. Agrawal’s services would be detrimental to our ongoing scientific progress and the execution of our business plan.
     We are a party to an employment agreement with Dr. Agrawal for a term commencing on April 1, 2002 and ending on April 1, 2007. The agreement is currently being amended to reflect Dr. Agrawal’s current responsibilities as Chief Executive Officer. This agreement may be terminated by us or Dr. Agrawal for any reason or no reason at any time upon notice to the other party. We do not carry key man life insurance for Dr. Agrawal.
     Furthermore, our future growth will require hiring a significant number of qualified technical and management personnel. Accordingly, recruiting and retaining such personnel in the future will be critical to our success. There is intense competition from other companies and research and academic institutions for qualified personnel in the areas of our activities. If we are not able to continue to attract and retain, on acceptable terms, the qualified personnel necessary for the continued development of our business, we may not be able to sustain our operations or grow.
Regulatory Risks
We may not be able to obtain marketing approval for products resulting from our development efforts.

20


Table of Contents

     All of the products that we are developing or may develop in the future will require additional research and development, extensive preclinical studies and clinical trials and regulatory approval prior to any commercial sales. This process is lengthy, often taking a number of years, is uncertain and is expensive. Since our inception, we have conducted clinical trials of a number of compounds. In 1997, we determined not to continue clinical development of GEM91, our lead product candidate at the time. Currently, we are conducting clinical trials of IMOxine, our lead IMO drug candidate.
     We may need to address a number of technological challenges in order to complete development of our products. Moreover, these products may not be effective in treating any disease or may prove to have undesirable or unintended side effects, unintended alteration of the immune system over time, toxicities or other characteristics that may preclude our obtaining regulatory approval or prevent or limit commercial use.
We are subject to comprehensive regulatory requirements, which are costly and time consuming to comply with; if we fail to comply with these requirements, we could be subject to adverse consequences and penalties.
     The testing, manufacturing, labeling, advertising, promotion, export and marketing of our products are subject to extensive regulation by governmental authorities in Europe, the United States and elsewhere throughout the world.
     In general, submission of materials requesting permission to conduct clinical trials may not result in authorization by the FDA or any equivalent foreign regulatory agency to commence clinical trials. In addition, submission of an application for marketing approval to the relevant regulatory agency following completion of clinical trials may not result in the regulatory agency approving the application if applicable regulatory criteria are not satisfied, and may result in the regulatory agency requiring additional testing or information.
     Any regulatory approval of a product may contain limitations on the indicated uses for which the product may be marketed or requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. Any product for which we obtain marketing approval, along with the facilities at which the product is manufactured, any post-approval clinical data and any advertising and promotional activities for the product will be subject to continual review and periodic inspections by the FDA and other regulatory agencies.
     Both before and after approval is obtained, violations of regulatory requirements may result in:
    the regulatory agency’s delay in approving, or refusal to approve, an application for approval of a product;
 
    restrictions on such products or the manufacturing of such products;
 
    withdrawal of the products from the market;
 
    warning letters;
 
    voluntary or mandatory recall;
 
    fines;
 
    suspension or withdrawal of regulatory approvals;
 
    product seizure;
 
    refusal to permit the import or export of our products;
 
    injunctions or the imposition of civil penalties; and
 
    criminal penalties.

21


Table of Contents

We have only limited experience in regulatory affairs and our products are based on new technologies; these factors may affect our ability or the time we require to obtain necessary regulatory approvals.
     We have only limited experience in filing the applications necessary to gain regulatory approvals. Moreover, the products that result from our research and development programs will likely be based on new technologies and new therapeutic approaches that have not been extensively tested in humans. The regulatory requirements governing these types of products may be more rigorous than for conventional drugs. As a result, we may experience a longer regulatory process in connection with obtaining regulatory approvals of any product that we develop.
Risks Relating to Collaborators
We need to establish collaborative relationships in order to succeed.
     An important element of our business strategy includes entering into collaborative relationships for the development and commercialization of products based on our discoveries. We face significant competition in seeking appropriate collaborators. Moreover, these arrangements are complex to negotiate and time-consuming to document. We may not be successful in our efforts to establish collaborative relationships or other alternative arrangements.
     The success of collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Our collaborators will have significant discretion in determining the efforts and resources that they will apply to these collaborations. The risks that we face in connection with these collaborations include the following:
    disputes may arise in the future with respect to the ownership of rights to technology developed with collaborators;
 
    disagreements with collaborators could delay or terminate the research, development or commercialization of products, or result in litigation or arbitration;
 
    we may have difficulty enforcing the contracts if one of our collaborators fails to perform;
 
    our collaborators may terminate their collaborations with us, which could make it difficult for us to attract new collaborators or adversely affect the perception of us in the business or financial communities;
 
    collaborators have considerable discretion in electing whether to pursue the development of any additional drugs and may pursue technologies or products either on their own or in collaboration with our competitors that are similar to or competitive with our technologies or products that are the subject of the collaboration with us; and
 
    our collaborators may change the focus of their development and commercialization efforts. Pharmaceutical and biotechnology companies historically have re-evaluated their priorities following mergers and consolidations, which have been common in recent years in these industries. The ability of our products to reach their potential could be limited if our collaborators decrease or fail to increase spending relating to such products.
     Given these risks, it is possible that any collaborative arrangements into which we enter may not be successful. In May 2005, we entered into collaborative arrangements with Novartis involving our IMO technology. Previous collaborative arrangements to which we were a party with F. Hoffmann-La Roche and G.D. Searle & Co, involving our antisense technology, both were terminated prior to the development of any product. The failure of any of our collaborative relationships could delay our drug development or impair commercialization of our products.
Risks Relating to Intellectual Property

22


Table of Contents

If we are unable to obtain patent protection for our discoveries, the value of our technology and products will be adversely affected.
     Our patent positions, and those of other drug discovery companies, are generally uncertain and involve complex legal, scientific and factual questions.
     Our ability to develop and commercialize drugs depends in significant part on our ability to:
    obtain patents;
 
    obtain licenses to the proprietary rights of others on commercially reasonable terms;
 
    operate without infringing upon the proprietary rights of others;
 
    prevent others from infringing on our proprietary rights; and
 
    protect trade secrets.
     We do not know whether any of our patent applications or those patent applications which we license will result in the issuance of any patents. Our issued patents and those that may issue in the future, or those licensed to us, may be challenged, invalidated or circumvented, and the rights granted thereunder may not provide us proprietary protection or competitive advantages against competitors with similar technology. Furthermore, our competitors may independently develop similar technologies or duplicate any technology developed by us. Because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any of our products can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thus reducing any advantage of the patent.
     Because patent applications in the United States and many foreign jurisdictions are typically not published until 18 months after filing, or in some cases not at all, and because publications of discoveries in the scientific literature often lag behind actual discoveries, neither we nor our licensors can be certain that we or they were the first to make the inventions claimed in issued patents or pending patent applications, or that we or they were the first to file for protection of the inventions set forth in these patent applications.
Third parties may own or control patents or patent applications and require us to seek licenses, which could increase our development and commercialization costs, or prevent us from developing or marketing products.
     We may not have rights under some patents or patent applications related to our products. Third parties may own or control these patents and patent applications in the United States and abroad. Therefore, in some cases, to develop, manufacture, sell or import some of our products, we or our collaborators may choose to seek, or be required to seek, licenses under third party patents issued in the United States and abroad or under patents that might issue from United States and foreign patent applications. In such an event, we would be required to pay license fees or royalties or both to the licensor. If licenses are not available to us on acceptable terms, we or our collaborators may not be able to develop, manufacture, sell or import these products.
We may lose our rights to patents, patent applications or technologies of third parties if our licenses from these third parties are terminated. In such an event, we might not be able to develop or commercialize products covered by the licenses.
     We are party to ten royalty-bearing license agreements under which we have acquired rights to patents, patent applications and technology of third parties. Under these licenses we are obligated to pay royalties on net sales by us of products or processes covered by a valid claim of a patent or patent application licensed to us. We also are required in some cases to pay a specified percentage of any sublicense income that we may receive. These licenses impose various commercialization, sublicensing, insurance and other obligations on us. Our failure to comply with these requirements could result in termination of the licenses. These licenses generally will otherwise remain in

23


Table of Contents

effect until the expiration of all valid claims of the patents covered by such licenses or upon earlier termination by the parties. The issued patents covered by these licenses expire at various dates ranging from 2006 to 2022. If one or more of these licenses is terminated, we may be delayed in our efforts, or be unable, to develop and market the products that are covered by the applicable license or licenses.
We may become involved in expensive patent litigation or other proceedings, which could result in our incurring substantial costs and expenses or substantial liability for damages or require us to stop our development and commercialization efforts.
     There has been substantial litigation and other proceedings regarding patent and other intellectual property rights in the biotechnology industry. We may become a party to various types of patent litigation or other proceedings regarding intellectual property rights from time to time even under circumstances where we are not practicing and do not intend to practice any of the intellectual property involved in the proceedings. For instance, in 2002 and 2003, we became involved in two interference proceedings declared by the United States Patent and Trademark Office, or USPTO, which have since been resolved. In June 2005, we became aware of a third interference declared by the USPTO related to our Ribozyme technology. We are neither practicing nor intending to practice the intellectual property that is associated with any of these interference proceedings.
     The cost to us of any patent litigation or other proceeding, including the interferences referred to above, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain the cost of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. If any patent litigation or other proceeding is resolved against us, we or our collaborators may be enjoined from developing, manufacturing, selling or importing our drugs without a license from the other party and we may be held liable for significant damages. We may not be able to obtain any required license on commercially acceptable terms or at all.
     Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Patent litigation and other proceedings may also absorb significant management time.
Risks Relating to Product Manufacturing, Marketing and Sales and Reliance on Third Parties
Because we have limited manufacturing experience, we are dependent on third-party manufacturers to manufacture products for us. If we cannot rely on third-party manufacturers, we will be required to incur significant costs and devote significant efforts to establish our own manufacturing facilities and capabilities.
     We have limited manufacturing experience and no commercial scale manufacturing capabilities. In order to continue to develop our products, apply for regulatory approvals and ultimately commercialize products, we need to develop, contract for or otherwise arrange for the necessary manufacturing capabilities.
     We currently rely upon third parties to produce material for preclinical and clinical testing purposes and expect to continue to do so in the future. We also expect to rely upon third parties to produce materials that may be required for the commercial production of our products.
     There are a limited number of manufacturers that operate under the FDA’s current good manufacturing practices regulations capable of manufacturing our products. As a result, we may have difficulty finding manufacturers for our products with adequate capacity for our needs. If we are unable to arrange for third party manufacturing of our products on a timely basis, or to do so on commercially reasonable terms, we may not be able to complete development of our products or market them.
     Reliance on third party manufacturers entails risks to which we would not be subject if we manufactured products ourselves, including:
    reliance on the third party for regulatory compliance and quality assurance,

24


Table of Contents

    the possibility of breach of the manufacturing agreement by the third party because of factors beyond our control,
 
    the possibility of termination or nonrenewal of the agreement by the third party, based on its own business priorities, at a time that is costly or inconvenient for us,
 
    the potential that third party manufacturers will develop know-how owned by such third party in connection with the production of our products that is necessary for the manufacture of our products, and
 
    reliance upon third party manufacturers to assist us in preventing inadvertent disclosure or theft of our proprietary knowledge.
     We purchased oligonucleotides for preclinical and clinical testing from Avecia Biotechnology at a preferential price under a supply agreement, which expired in March 2004. We have continued to purchase all of the oligonucleotides we are using in our ongoing clinical trials and pre-clinical testing from Avecia. The terms of the agreement have been extended until such time as a new agreement is negotiated. If Avecia determines not to accept any purchase order for oligonucleotides or we are unable to enter into a new manufacturing arrangement with Avecia or a new contract manufacturer on a timely basis or at all, our ability to supply the product needed for our clinical trials could be materially impaired.
We have no experience selling, marketing or distributing products and no internal capability to do so.
     If we receive regulatory approval to commence commercial sales of any of our products, we will face competition with respect to commercial sales, marketing and distribution. These are areas in which we have no experience. To market any of our products directly, we would need to develop a marketing and sales force with technical expertise and with supporting distribution capability. In particular, we would need to recruit a large number of experienced marketing and sales personnel. Alternatively, we could engage a pharmaceutical or other healthcare company with an existing distribution system and direct sales force to assist us. However, to the extent we entered into such arrangements, we would be dependent on the efforts of third parties. If we are unable to establish sales and distribution capabilities, whether internally or in reliance on third parties, our business would suffer materially.
If third parties on whom we rely for clinical trials do not perform as contractually required or as we expect, we may not be able to obtain regulatory approval for or commercialize our products and our business may suffer.
     We do not have the ability to independently conduct the clinical trials required to obtain regulatory approval for our products. We depend on independent clinical investigators, contract research organizations and other third party service providers in the conduct of the clinical trials of our products and expect to continue to do so. For example, we have contracted with PAREXEL International to manage our Phase 2 clinical trials of IMOxine. We rely heavily on these parties for successful execution of our clinical trials, but do not control many aspects of their activities. We are responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with standards, commonly referred to as good clinical practices, for conducting, recording and reporting clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Third parties may not complete activities on schedule or may not conduct our clinical trials in accordance with regulatory requirements or our stated protocols. The failure of these third parties to carry out their obligations could delay or prevent the development, approval and commercialization of our products. If we seek to conduct any of these activities ourselves in the future, we will need to recruit appropriately trained personnel and add to our infrastructure.
If we are unable to obtain adequate reimbursement from third party payors for any products that we may develop or acceptable prices for those products, our revenues and prospects for profitability will suffer.

25


Table of Contents

     Most patients will rely on Medicare and Medicaid, private health insurers and other third party payors to pay for their medical needs, including any drugs we may market. If third party payors do not provide adequate coverage or reimbursement for any products that we may develop, our revenues and prospects for profitability will suffer. Congress recently enacted a limited prescription drug benefit for Medicare recipients in the Medicare Prescription Drug and Modernization Act of 2003. While the program established by this statute may increase demand for our products, if we participate in this program, our prices will be negotiated with drug procurement organizations for Medicare beneficiaries and are likely to be lower than we might otherwise obtain. Non-Medicare third party drug procurement organizations may also base the price they are willing to pay on the rate paid by drug procurement organizations for Medicare beneficiaries.
     A primary trend in the United States healthcare industry is toward cost containment. In addition, in some foreign countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take six to 12 months or longer after the receipt of regulatory marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost effectiveness of our product candidates or products to other available therapies. The conduct of such a clinical trial could be expensive and result in delays in commercialization of our products.
     Third party payors are challenging the prices charged for medical products and services, and many third party payors limit reimbursement for newly-approved healthcare products. In particular, third party payors may limit the indications for which they will reimburse patients who use any products that we may develop. Cost control initiatives could decrease the price we might establish for products that we may develop, which would result in lower product revenues to us.
We face a risk of product liability claims and may not be able to obtain insurance.
     Our business exposes us to the risk of product liability claims that is inherent in the manufacturing, testing and marketing of human therapeutic drugs. Although we have product liability and clinical trial liability insurance that we believe is adequate, this insurance is subject to deductibles and coverage limitations. We may not be able to obtain or maintain adequate protection against potential liabilities. If we are unable to obtain insurance at acceptable cost or otherwise protect against potential product liability claims, we will be exposed to significant liabilities, which may materially and adversely affect our business and financial position. These liabilities could prevent or interfere with our commercialization efforts.
Risks Relating to an Investment in Our Common Stock
Our corporate governance structure, including provisions in our certificate of incorporation and by-laws, our stockholder rights plan and Delaware law, may prevent a change in control or management that stockholders may consider desirable.
     Section 203 of the Delaware General Corporation Law and our certificate of incorporation, by-laws and stockholder rights plan contain provisions that might enable our management to resist a takeover of our company or discourage a third party from attempting to take over our company. These provisions include:

     These provisions could have the effect of delaying, deferring, or preventing a change in control of us or a change in our management that stockholders may consider favorable or beneficial. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors and take other corporate actions. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock.
Our stock price has been and may in the future be extremely volatile. In addition, because an active trading market for our common stock has not developed, our investors’ ability to trade our common stock may be limited. As a result, investors may lose all or a significant portion of their investment.
     Our stock price has been volatile. During the period from January 1, 2003 to June 30, 2005, the closing sales price of our common stock ranged from a high of $1.69 per share to a low of $0.41 per share. The stock market has also experienced significant price and volume fluctuations, and the market prices of biotechnology companies in particular have been highly volatile, often for reasons that have been unrelated to the operating performance of particular companies. The market price for our common stock may be influenced by many factors, including:
    results of clinical trials of our product candidates or those of our competitors;
 
    the regulatory status of our product candidates;
 
    failure of any of our product candidates, if approved, to achieve commercial success;
 
    the success of competitive products or technologies;
 
    regulatory developments in the United States and foreign countries;
 
    developments or disputes concerning patents or other proprietary rights;
 
    the departure of key personnel;
 
    variations in our financial results or those of companies that are perceived to be similar to us;
 
    our cash resources;
 
    the terms of any financing conducted by us;
 
    changes in the structure of healthcare payment systems;
 
    market conditions in the pharmaceutical and biotechnology sectors and issuance of new or changed securities analysts’ reports or recommendations; and
 
    general economic, industry and market conditions.
     In addition, our common stock has historically been traded at low volume levels and may continue to trade at low volume levels. As a result, any large purchase or sale of our common stock could have a significant impact on the price of our common stock and it may be difficult for investors to sell our common stock in the market without depressing the market price for the common stock or at all.
     As a result of the foregoing, investors may not be able to resell their shares at or above the price they paid for such shares. Investors in our common stock must be willing to bear the risk of fluctuations in the price of our common stock and the risk that the value of their investment in our stock could decline.

We may be unable to repay our 4% convertible subordinated notes when due or to repurchase the convertible subordinated notes if we are required to do so under the terms of our agreement with the holders of the 4% convertible subordinated notes.
     In May 2005, we sold approximately $5.0 million in principal amount of 4% convertible subordinated notes. On April 30, 2008, the entire outstanding principal amount of our 4% convertible subordinated notes will become due and payable. In addition, we may be required to redeem all or part of the convertible subordinated notes prior to the final maturity date if specified events occur. We may not have sufficient funds or may be unable to arrange for additional financing to pay the amount due under the convertible subordinated notes at maturity or to pay the price to repurchase the convertible subordinated notes. Any future borrowing arrangements or debt agreements to which we may become a party may restrict or prohibit us from repaying or repurchasing the convertible subordinated notes. If we are prohibited from repaying or repurchasing the convertible subordinated notes, we could try to obtain the consent of lenders under those arrangements, or we could attempt to refinance the indebtedness that contains the restrictions. If we could not obtain the necessary consents or refinance the indebtedness, we would be unable to repay or repurchase the convertible subordinated notes. Any such failure would constitute an event of default under the agreement with the holders of the 4% convertible subordinated notes, which could, in turn, constitute a default under the terms of any future indebtedness.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
     Historically, our primary exposures have been related to nondollar-denominated operating expenses in Europe. As of June 30, 2005, we have no assets and liabilities related to nondollar-denominated currencies.
     We maintain investments in accordance with our investment policy. The primary objectives of our investment activities are to preserve principal, maintain proper liquidity to meet operating needs and maximize yields. Although our investments are subject to credit risk, our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure from any single issue, issuer or type of investments. We do not own derivative financial investment instruments in our investment portfolio.
     Based on a hypothetical ten percent adverse movement in interest rates, the potential losses in future earnings, fair value of risk sensitive financial instruments, and cash flows are immaterial, although the actual effects may differ materially from the hypothetical analysis.
ITEM 4. CONTROLS AND PROCEDURES
     (a) Evaluation of Disclosure Controls and Procedures. Our management, with the participation of our chief executive officer and our chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2005. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2005, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
     (b) Changes in Internal Controls. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act) occurred during the fiscal quarter ended June 30, 2005 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
