HYBRIDON, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

MARCH 31, 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 immunomodulatory 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. In 2003 and 2004, Hybridon 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 existing cash, cash equivalents and short-term investments will be sufficient to fund operations midway through the first quarter of 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 midway through the first quarter of 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-month period ended March 31, 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 March 31,  
    2005     2004  
Numerator:
               
Net loss
  $ (3,222,344 )   $ (2,732,894 )
Accretion of preferred stock dividends
    (164 )     (2,675,519 )
 
           
Numerator for basic and diluted loss per share applicable to common stockholders
  $ (3,222,508 )   $ (5,408,413 )
 
           
Denominator for basic and diluted loss per share
    110,967,025       80,972,146  
 
           
Loss per share – basic and diluted:
               
Net loss per share
  $ (0.03 )   $ (0.04 )
Accretion of preferred stock dividends
          (0.03 )
 
           
Net loss per share applicable to common stockholders
  $ (0.03 )   $ (0.07 )
 
           

     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 months ended March 31, 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 potential common stock equivalents are antidilutive. Total antidilutive securities were 32,121,929 and 24,983,929 for the three months ended March 31, 2005 and 2004, respectively. These antidilutive securities include stock options, warrants and convertible preferred stock and are not included in the Company’s calculation of diluted net loss per common share. Antidilutive securities for the three months ended March 31, 2004 also included convertible debt instruments on an as-converted basis.

(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 March 31, 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 March 31, 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 for the three-month periods ended March 31, 2005 and 2004. There were no losses or permanent declines in value included in “investment income” for any securities in the three months ended March 31, 2005 and 2004.

Table of Contents

     The Company had no long-term investments as of March 31, 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 March 31, 2005 and December 31, 2004:

                 
    March 31,     December 31,  
    2005     2004  
Short-term available-for-sale investments at market value:
               
Corporate bonds
  $     $ 2,004,150  
Government bonds
    2,990,280       2,986,990  
Auction securities
    4,400,000       4,400,000  
 
           
Total
  $ 7,390,280     $ 9,391,140  
 
           

(5) Property and Equipment

     At March 31, 2005 and December 31, 2004, net property and equipment at cost consists of the following:

                 
    March 31,     December 31,  
    2005     2004  
Leasehold improvements
  $ 424,500     $ 424,500  
Laboratory equipment and other
    1,703,723       1,804,799  
 
           
Total property and equipment, at cost
    2,128,223       2,229,299  
Less: Accumulated depreciation and amortization
    1,807,166       1,877,508  
 
           
Property and equipment, net
  $ 321,057     $ 351,791  
 
           

     In the first quarter of 2005, the Company wrote off unused property and equipment that had a gross 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 $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 March 31, 2005, the Company recognized approximately $84,000 as stock compensation expense from repriced options as a result of an increase in the intrinsic value of these options between December 31, 2004 and March 31, 2005. For the three months ended March 31, 2004, the Company recognized a credit of approximately $317,000 for stock compensation from repriced options as a result of a decrease in the intrinsic value of these options between December 31, 2003 and March 31, 2004. As of March 31, 2005 and 2004, respectively, options to purchase 2,371,922 and 2,431,549 shares were 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

Table of Contents

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 three months ended March 31, 2004 the Company recorded $3.2 million of preferred stock dividends related to the additional shares issued. During the 60-day conversion period, 99.9% of the Series A convertible preferred stock was converted to common stock.

     The combined effects of the amendments to the Company’s Restated Certificate of Incorporation and the Series A convertible preferred stock conversions are as follows:

                         
    December 3, 2003     December 31, 2003     February 2, 2004  
Shares:
                       
Series A convertible preferred stock outstanding
    722,727       489,205       635  
Common stock issued upon conversions (cumulative)
          6,868,288       21,238,028  
Common stock outstanding
    63,595,442       70,482,570       84,900,627  
Series A preferred liquidation preference
  $ 73,055,654     $ 494,912     $ 643  
Annual dividend amount
  $ 4,697,726     $ 937,643     $ 864  

     From January 1, 2004 through March 31, 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 three month period ended March 31, 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.

     As a result of the amendments to the Company’s Restated Certificate of Incorporation and the Series A convertible preferred stock conversions, the Series A convertible preferred stock liquidation preference was reduced from $73,055,654 at December 3, 2003 to $494,912 at December 31, 2003 and $643 at March 31, 2004.

(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 months ended March 31, 2005 and 2004 would be as follows:

                 
    March 31,  
    2005     2004  
Net loss applicable to common stockholders, as reported
  $ (3,222,508 )   $ (5,408,413 )
Less: stock-based compensation expense (income) included in reported net loss
    83,753       (317,138 )
Add: stock-based employee compensation expense determined under fair value based method for all awards
    (216,072 )     (205,735 )
 
           
Pro forma net income (loss) applicable to common stockholders, as adjusted for the effect of applying SFAS No. 123

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 immunomodulatory 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. In 2004, we 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.

     Since we began operations in February 1990, we have been involved primarily in research and development and manufacturing. To date, almost all of our revenues have been from collaborative and license agreements. In addition, we generated revenues from the sale of synthetic DNA and reagent products manufactured by our Hybridon Specialty Products Division, or HSP, prior to our selling HSP in September 2000. The sale of HSP together with the sale of our interest in Methylgene, our first spin-off company, and net proceeds from our Collaboration and License Agreement with Isis Pharmaceuticals, Inc. generated approximately $52.5 million.

     We have incurred total losses of $302.5 million through March 31, 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

10


Table of Contents

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 conditions or operating performance is material.

     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 Months Ended March 31, 2005 and 2004

  Alliance Revenue

     Total alliance revenue decreased by $474,000, or 73%, from $645,000 for the three months ended March 31, 2004 to $171,000 for the three months ended March 31, 2005. Our revenues for both periods were comprised of revenue earned under various collaboration and licensing agreements for research and development, including reimbursement of third party expenses, license fees, sublicense fees, and royalty payments. The decrease in the first quarter of 2005 primarily reflects the revenue we recognized in the first quarter of 2004 in connection with supplying product to a collaborator for use in clinical trials and milestone revenue we earned in the first quarter of 2004, for which there was not comparable revenue earned in the first quarter of 2005.

  Research and Development Expenses

     Research and development expenses decreased by $206,000, or 7%, from $2,805,000 for the three months ended March 31, 2004 to $2,599,000 for the three months ended March 31, 2005. The decrease in the first quarter of 2005 was primarily attributable to a decrease in compensation and associated recruiting expenses. The decrease also reflects the cost of clinical supplies we incurred in the first quarter of 2004 to supply a collaborator under one of our collaboration and licensing agreements for which there was no comparable expense in the first quarter of 2005. These decreases were offset by our purchase of raw materials in the first quarter of 2005 for the production of clinical drug supplies to be utilized in our ongoing and future clinical trials of IMOxine. 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 the three months ended March 31, 2005 and 2004, we incurred approximately $0.7 million and $0.6 million, respectively, in direct external expenses to develop HYB2055. 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 one year, treatment under the protocol was completed in June 2004.

     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 $119,000, or 13%, from $897,000 in the three months ended March 31, 2004 to $778,000 in the three months ended March 31, 2005. The decrease primarily reflects lower compensation costs and lower insurance expenses in the first quarter of 2005. Other than these decreases, general and administrative expenses in the first quarter of 2005 were consistent with general and administrative expenses in the first quarter of 2004. These expenses consisted primarily of salaries, professional legal fees associated with our regulatory filing requirements and business development.

  Stock-Based Compensation

     As a result of our 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. For the three months ended March 31, 2005, we incurred stock-based compensation expense of $84,000 in operating results, which resulted from an increase in the intrinsic value of these options from December 31, 2004 to March 31, 2005. For the three months ended March 31, 2004, we recorded a credit of approximately $317,000 as a result of a decrease in the intrinsic value of these options from December 31, 2003 to March 31, 2004. We expect that compensation charges and credits may occur in the future based upon changes in the intrinsic value of our repriced stock options. Since all of the repriced options are fully vested, these compensation charges and credits will cease upon pending adoption of 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”.

  Investment Income, net

     Investment income increased by approximately $31,000, or 86%, from $36,000 in the three months ended March 31, 2004 to $67,000 in the three months ended March 31, 2005. This increase resulted from higher interest rates on higher cash and investment balances and less premium amortization offsetting interest income in 2005.

  Interest Expense

     We had no interest expense for the three months ended March 31, 2005. For the three months ended March 31, 2004, interest expense of approximately $29,000 related to the 9% Notes which matured and were repaid in full on April 1, 2004.

  Preferred Stock Dividends

     Accretion of preferred stock dividends decreased by approximately $2,676,000, or 100%, from $2,676,000 for the three months ended March 31, 2004 to nearly zero for the three months ended March 31, 2005. The decrease for the three-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 addition to dividends in the statement of operations at the time of conversion.

Table of Contents

     For the three months ended March 31, 2004, we recorded approximately $3,245,000 of preferred stock dividends related to the additional shares issued in connection with the conversion of Series A convertible preferred stock into common stock. This additional $3,245,000 dividend was partially offset by a reversal of $570,000 of dividends that were accreted in the fourth quarter of 2003 with respect to these shares but were reversed during the three months ended March 31, 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 $3,223,000 for the three months ended March 31, 2005, as compared to $5,408,000 for the three months ended March 31, 2004.

LIQUIDITY AND CAPITAL RESOURCES

Sources of Liquidity

     We require cash to fund our operating expenses, to make capital expenditures and to pay debt service. Historically, we have funded our cash requirements primarily through the following:

  •   equity and debt financing;
 
  •   license fees and research funding under collaborative and license agreements;
 
  •   interest income; and
 
  •   lease financings.

We have also funded our cash requirements through the following:

  •   manufacturing of synthetic DNA and reagent products within HSP prior to its sale in 2000;
 
  •   the sale of HSP for which we received a total of $15.0 million in 2000 and 2001; and
 
  •   the sale of our shareholding in MethylGene Inc. for which we received net proceeds of $6.9 million in 2001.

Cash Flows

     As of March 31, 2005, we had approximately $11,087,000 in cash, cash equivalents and short-term investments, a decrease of approximately $3,326,000 from December 31, 2004.

     We used $3,346,000 of cash for operating activities during the three months ended March 31, 2005, principally to fund our research and development expenses and our general and administrative expenses. The $3,346,000 primarily consists of our net loss of $3,222,000 for the period, as adjusted for the increase in our prepaid expenses reflecting annual insurance premiums paid at the beginning of the year and our accrued expenses reflecting charges for raw materials purchased for future manufacturing of our drug products.

     Net cash provided by investing activities reflects the proceeds of $2,000,000 that we received from the sale of “available-for-sale” securities in the three months ended March 31, 2005.

     Net cash provided by financing activities reflects the approximately $29,000 we received from the exercise of stock options during the three months ended March 31, 2005.

     As of March 31, 2005, we had no outstanding indebtedness.

Funding Requirements

     Based on our current operating plan, we believe that our existing cash, cash equivalents and short-term investments will be sufficient to fund operations midway through the first quarter of 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.

     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 many 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 midway through the first quarter of 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.

     We may not be successful in generating funds internally or from external sources on a timely basis, on acceptable terms or at all. If we are unable to obtain additional funds in the future, we may be required to delay, scale back or eliminate some or all of our research and development programs.

Contractual Obligations

     We have contractual obligations in the form of employment agreements, operating leases and consulting and collaboration agreements.
