NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

     The unaudited condensed consolidated financial statements included in this quarterly report have been prepared by Targeted Genetics Corporation, or Targeted Genetics, without audit, according to the rules and regulations of the Securities and Exchange Commission, or SEC. Our condensed consolidated financial statements include the accounts of Targeted Genetics, our wholly owned subsidiaries Genovo, Inc. (inactive) and TGCF Manufacturing Corporation (inactive), and our majority-owned subsidiary, CellExSys, Inc., or CellExSys. CellExSys was merged into Chromos Molecular Systems, Inc., or Chromos, on July 27, 2004. The condensed consolidated balance sheet as of December 31, 2003, and our results of operations for the three and six months ended June 30, 2003, do not include the accounts of Emerald Gene Systems, Ltd., or Emerald, our majority-owned research and development joint venture with Elan International Services Ltd., or Elan, because we did not have operating control of Emerald during those periods. In connection with a termination agreement with Elan effective March 31, 2004, we acquired all of Elan’s equity interest in Emerald. As a result, Emerald became a wholly-owned subsidiary as of March 31, 2004, and is consolidated into our financial statements as of that date. The operations of Emerald terminated during 2002; therefore, the impact of consolidating the accounts of Emerald into our financial results is not significant. We are in the process of dissolving Emerald. All significant inter-company transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted in accordance with the SEC’s rules and regulations. The financial statements reflect, in the opinion of management, all adjustments which consist solely of normal recurring adjustments necessary to present fairly our financial position and results of operations as of and for the periods indicated. Certain reclassifications have been made to conform prior period results to the current period presentation.

     We do not believe that our results of operations for the three and six months ended June 30, 2004 are necessarily indicative of the results to be expected for the full year.

     The unaudited condensed consolidated financial statements included in this quarterly report should be read in conjunction with our audited consolidated financial statements and related footnotes included in our annual report on Form 10-K for the year ended December 31, 2003.

Total long-term obligations
  $ 10,873,000     $ 11,227,000  
 
   
 
     
 
 

     Future aggregate principal payments related to long-term obligations are $1,139,000 for the remainder of 2004, $1,092,000 in 2005, $10,140,000 in 2006 and $13,000 in 2007.

3. Accrued Restructure Charges

     We record accrued restructure charges as they relate to the leases on our facilities in Bothell, Washington and Sharon Hill, Pennsylvania. In December 2002, we began to pursue options to sublease or terminate our lease on the Bothell facility and in February 2003, we closed our Sharon Hill facility. Accrued restructure charges represent our best estimate of the fair value of the liability as determined under Statement of Financial Accounting Standards, or SFAS, No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” and is computed as the fair value of the difference between the remaining lease payments due on these leases and the estimated sub-lease market rates. These assumptions are periodically reviewed and updated as appropriate and adjustment is made to the accrued restructure charge. Accretion expense is also recorded on an ongoing basis and results from the difference between the fair value of payments in the estimate of accrued restructure liability compared to actual payments made during the quarter. Accretion expense is reflected as a restructure charge on the consolidated statements of operations. To the extent that a portion of our facilities are not being offered for sublease, the cost of the assumed sublease income is recognized ratably as research and development expense over the remaining term of the lease.

     If we proceed with further development or commercialization of any of our product candidates, we may need to resume use of the Bothell facility to fulfill our manufacturing requirements. If we decide to resume use of this facility, any remaining accrued restructure charges related to the manufacturing facility will be reversed and recorded as a one-time credit to restructure charges, reflected in the period in which use is resumed. Any decision to resume use of the facility will be based on a number of factors, including the progress of our product candidates in clinical development, the estimated duration of facility design and construction, the estimated timing of product manufacturing requirements, the ability of our current manufacturing capabilities to meet demand, and the availability of resources. However, unless we resume use of the Bothell facility, we will continue to account for the lease in accordance with SFAS No. 146 and will periodically evaluate the assumptions and record additional restructure charges if necessary. Because we compute restructure charges using estimates and assumptions regarding the timing and amounts of future events, further significant adjustments to the accrual may be necessary based on the actual outcome of events and as we become aware of new facts and circumstances.

     The charges in 2004 represent accretion expense on the accrued restructure charges of $270,000 and an additional charge of $146,000 due to a change in estimate related to the Sharon Hill facility to reflect our belief that we can not secure a sublease tenant prior to the expiration of the lease. Estimated future charges represent our estimate of the accretion expense throughout the remainder of the lease term.

4. Shareholders’ Equity

     Stock Option Increase and Conversion of Series B Preferred Stock

     In May 2004, our shareholders approved an increase in the number of shares of common stock issuable under our 1999 Stock Option Plan by 6,000,000, from 3,500,000 to 9,500,000 shares. Effective March 31, 2004, Elan converted the Series B preferred stock it held into 4,330,000 shares of our common stock. Shares reserved for future issuance are as follows:

                 
    June 30,   December 31,
    2004
  2003
Issued and outstanding stock options
    6,277,840       4,097,687  
Shares available for future stock option grants
    4,072,360       322,927

Conversion of Series B preferred stock
          4,765,500  
 
   
 
     
 
 
Total reserved shares
    12,350,200       11,189,940  
 
   
 
     
 
 

   Stock Compensation

     As permitted by the provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” we have elected to follow Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations in accounting for employee stock option grants. In addition, we follow the disclosure requirements of SFAS No. 148, “Accounting for Stock-Based Compensation – Transition and Disclosure – an amendment of SFAS No. 123,” which require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. We do not recognize any compensation expense for options granted to employees because we grant all options at fair market value on the date of grant. Options and warrants to purchase common stock granted to non-employees or directors are recorded as an expense over their service period based on their fair value, which is determined using the Black-Scholes method.

     As allowed by SFAS No. 123, we do not recognize compensation expense on stock options or warrants granted to employees and directors. If we had elected to recognize compensation expense based on the fair market value at the grant dates for stock options granted, the pro forma net loss and net loss per common share would have been as follows:

5. Merger Agreement Between CellExSys, Inc. and Chromos Molecular Systems, Inc.

     On July 27, 2004, Chromos acquired all of the outstanding shares of CellExSys through a merger between CellExSys and Chromos Inc., a wholly owned subsidiary of Chromos. Under the terms of the merger agreement, Chromos has issued to CellExSys shareholders 1,500,000 shares of Chromos common stock and a secured convertible debenture totaling approximately $2.5 million. The debenture bears annual interest of 2% and is payable in two annual installments on the first and second anniversary of the closing.

     Each shareholder of CellExSys will receive a pro rata distribution of Chromos common stock and principal and interest payments received on the debenture, based on the shareholder’s equity interest in CellExSys as of July 27, 2004, the date of closing. We owned approximately 79% of CellExSys at the time of the merger. The debenture is repayable by Chromos at its option in either cash or by the issuance of shares of Chromos common stock, assuming certain limited conditions are met by Chromos. In combination with the shares of Chromos common stock issued at closing, if the debenture is fully paid in shares of Chromos common stock, the shareholders of CellExSys would receive up to 3.5 million shares, which represents approximately 17.2 percent of Chromos, based on issued and outstanding shares of Chromos as of the date of closing. The value of these 3.5 million shares as of the date of closing was approximately $1.4 million. Chromos has funded certain of CellExSys’ operational costs through the closing of the merger. This funding totaled $502,000 and is reflected as current portion of long-term obligations in the condensed consolidated balance sheets. As a result of the merger, we will record a gain during the quarter ended September 30, 2004 equal to the combination of 1) the net liabilities assumed by Chromos, 2) the deposits received from Chromos to fund pre-closing operating costs and 3) our pro-rata share of the fair value of the merger consideration. Subsequent to the merger, we have agreed to provide certain transition services and assistance to CellExSys for a limited period of time, which CellExSys will pay on a monthly basis.

Forward-Looking Statements

     This quarterly report on Form 10-Q contains forward-looking statements that involve risks and uncertainties. Forward-looking statements include statements about our product development and commercialization goals and expectations, potential market opportunities, our plans for and anticipated results of our clinical development activities and the potential advantage of our product candidates, and other statements that are not historical facts. Words such as “may,” “will,” “believes,” “estimates,” “expects,” “anticipates,” “plans” and “intends,” or statements concerning “potential” or “opportunity” and other words of similar meaning or the negative thereof, may identify forward-looking statements, but the absence of these words does not mean that the statement is not forward-looking. In making these statements, we rely on a number of assumptions and make predictions about the future. Our actual results could differ materially from those stated in, or implied by, forward-looking statements for a number of reasons, including the risks described in the section entitled “Factors Affecting Our Operating Results, Our Business and Our Stock Price” in Part I, Item 2 of this quarterly report.

     You should not unduly rely on these forward-looking statements, which speak only as of the date of this quarterly report. We undertake no obligation to publicly revise any forward-looking statement after the date of this quarterly report to reflect circumstances or events occurring after the date of this quarterly report or to conform the statement to actual results or changes in our expectations. You should, however, review the factors, risks and other information we provide in the reports we file from time to time with the SEC.

Business Overview

     Targeted Genetics Corporation develops gene therapy products and technologies for treating both acquired and inherited diseases. Our gene therapy product candidates are designed to treat disease by regulating cellular function at a genetic level. This involves introducing genetic material into target cells and activating it in a manner that provides the desired effect. We have assembled a broad base of proprietary intellectual property that we believe gives us the potential to address the significant diseases that are the primary focus of our business. Our proprietary intellectual property includes genes, methods of transferring genes into cells, processes to manufacture our lead gene delivery product candidates and other proprietary technologies and processes. In addition, we have established expertise and development capabilities focused in the areas of preclinical research and biology, manufacturing and manufacturing process scale-up, quality control, quality assurance, regulatory affairs and clinical trial design and implementation. We believe that our focus and expertise will enable us to develop products based on our proprietary intellectual property.

     Gene therapy products involve the use of delivery vehicles, called vectors, to place genetic material into target cells. Our proprietary vector technologies include both viral and synthetic vectors. Our viral vector development activities, which use modified viruses to deliver genes into cells, focus primarily on adeno-associated virus, or AAV, a common virus that has not been associated with any human disease or illness. We believe that AAV provides a number of safety and gene delivery advantages over other viruses for several of our potential gene therapy products. Our synthetic vectors deliver genes into cells using lipids, which are fatty, water-insoluble organic substances that can promote gene uptake through cell membranes. We believe that synthetic vectors may provide a number of gene delivery advantages for repeated, efficient delivery of therapeutic genes into rapidly dividing cells, such as certain types of tumor cells. Although our current product development candidates utilize AAV as the delivery vector, we believe that possessing capabilities in both viral and synthetic approaches provides advantages in our corporate partnering efforts and increases the range of our potential products that may reach the market.

     We have an AAV-based product candidate under development for treating cystic fibrosis that is being evaluated in a second Phase II clinical trial initiated in July 2003. We designed this trial to enroll up to 100 patients and are conducting it in collaboration with the Cystic Fibrosis Foundation, or CF Foundation. In June 2004, we announced that an independent data monitoring committee, or DMC, met for a scheduled interim analysis of this Phase II clinical trial. Based upon its review, the DMC recommended continuation of the study as planned. The DMC provided its recommendation based upon an analysis of whether or not there was a chance that, upon full patient enrollment, the study could show a statistically significant positive impact on lung function measurements in patients treated with tgAAVCF compared to placebo. We expect to complete patient accrual and dosing by the end of 2004. This second Phase II trial follows an initial repeat dosing trial for which we announced final data in June 2003. Data from this trial showed a good safety profile and indicated a statistically significant improvement in lung function at day 30 and a decrease in levels of an inflammatory cytokine at day 14 in patients treated with tgAAVCF when compared to placebo.

     We are developing an AAV-based vaccine product candidate for high-risk populations in developing nations to protect against the progression of Human Immunodeficiency Virus, or HIV, infection to Acquired Immune Deficiency Syndrome, or AIDS, in partnership with the International AIDS Vaccine Initiative, or IAVI, a non-profit organization, and The Columbus Children’s

Table of Contents

Research Institute at Children’s Hospital in Columbus, Ohio, or CCRI. In December 2003, we initiated a Phase I initial dose escalation safety trial in humans for our AIDS vaccine product candidate in Europe. This dose-escalation safety trial is designed to enroll up to 50 volunteers who are uninfected with HIV and in good health. Each participant in this trial will receive a single injection of the vaccine candidate or placebo and will be monitored for safety and immune response. We expect to complete the dose-escalation phase of this trial by the end of 2004.

     We are also developing an AAV-based product candidate for the treatment of rheumatoid arthritis. In March 2004, we initiated a Phase I clinical trial for this product candidate for treating rheumatoid arthritis. This dose-escalation safety trial is designed to enroll up to 32 patients with rheumatoid arthritis and will be conducted at multiple sites in the United States and Canada. Patients will be monitored for safety and secondarily for improvements in arthritis signs and symptoms. We expect to complete patient accrual and dosing in this trial by the first quarter of 2005. We have additional product candidates focused on treating cancer and hemophilia; however, we have suspended further development of these programs until we can find other sources of funding for the programs.

     We have developed processes to manufacture our potential products using methods and at a scale amenable to clinical development and expandable to large-scale production for advancing our potential products to clinical evaluation and commercialization. These methods are similar to the methods used to manufacture other biologics. As a result, we evaluated and continue to evaluate opportunities to utilize excess capacity to manufacture biologics for other companies. In March 2003, we entered into a manufacturing services agreement with GenVec, Inc., or GenVec, to manufacture clinical supply of GenVec’s cancer product candidate, TNFerade™, an adeno-viral-based gene therapy product. In January 2004, we completed our manufacturing work for GenVec.

     We believe that a wide range of diseases may potentially be treated, or prevented, with gene-based products, including cancer, genetic diseases and infectious diseases. We believe that there is also a significant opportunity to treat diseases that are currently treated using proteins and monoclonal antibodies, or small molecule drugs. These diseases may be more effectively treated by gene-based therapies due to their ability to provide a long-term or a localized method of treatment. Our business strategy is to develop multiple gene delivery systems, which we believe will maximize our product opportunities. Using AAV gene delivery systems, we are developing product candidates across multiple diseases with the belief that gene-based therapies may provide a means to treat diseases not fully treatable with current biologic and pharmaceutical drugs. We believe that, if successful, we can establish significant market potential for our product candidates. There currently are no commercially available gene therapy products in the United States. We intend to pursue product development programs to enable us to demonstrate proof of concept and eventually commercialize gene-based therapeutics to address currently unmet medical needs in treating disease.

     The development of pharmaceutical products involves extensive preclinical development followed by human clinical trials that take several years or more to complete. The length of time required to completely develop any product candidate varies substantially according to the type, complexity and novelty of the product candidate, the degree of involvement by a development partner, and the intended use of the product candidate. Our commencement and rate of completion of clinical trials may vary or be delayed for many reasons, including those discussed in the section entitled “Factors Affecting Our Operating Results, Our Business and Our Stock Price” in Part I, Item 2 of this quarterly report.

Results of Operations

     Revenue

          Revenue. Revenue increased to $2.8 million for the three months ended June 30, 2004 from $2.1 million for the same period in 2003. This increase in revenue reflects higher research and development activities under our AIDS vaccine collaboration with IAVI and revenue from completing our contract manufacturing agreement with GenVec, partially offset by no corresponding revenue for Biogen, Inc., or Biogen, in 2004. Revenue decreased to $4.1 million for the six months ended June 30, 2004 from $7.7 million for the same period in 2003. Revenue for the six months ended June 30, 2003 includes $3.9 million of revenue related to the termination of our collaboration with Wyeth Pharmaceuticals, or Wyeth, in February 2003 and $1.7 million of previously deferred payments received from Biogen under a collaboration that ended in September 2003.

          We expect that our revenue for the remainder of 2004 will consist of research and development revenue from our collaboration with IAVI, which we expect will increase through the remainder of 2004 as planned program activities increase. As a result of the conclusion of our former collaborations with Biogen and Wyeth in 2003, we expect total revenue in 2004 to be less than 2003. Our revenue for the next several years will depend on the continuation of the current collaboration with IAVI and our success with entering into and performing under potential new collaborations.

     Operating Expenses

          Research and Development Expenses. Research and development expenses increased to $4.8 million for the three months ended June 30, 2004 from $4.3 million for the same period in 2003, and increased to $9.1 million for the six months ended June 30, 2004 from $8.9 million for the same period in 2003. These increases reflect higher costs in our AIDS vaccine and rheumatoid arthritis programs, which moved out of preclinical development and into clinical testing in late 2003 and early 2004. As a result, the costs associated with these programs are included in the costs of programs in clinical development, which increased in 2004 compared to 2003.

          The following is an allocation of our total research and development costs between our programs in clinical development and those that are in research or preclinical stages of development:

          Research and development costs attributable to programs in clinical development include the applicable costs of salaries, benefits, clinical trials, outside services, materials and supplies incurred to support the programs, and any preclinical activities conducted in support of the clinical program. Indirect costs allocated to clinical programs include facility and occupancy costs, research and development administrative costs, and license and royalty payments. Our development partners separately fund the clinical trial costs of our cystic fibrosis and AIDS vaccine programs. As a result, we do not include those costs in our research and development expenses.

          Costs attributed to research and preclinical programs represent our earlier stage development activities, including costs incurred on programs prior to their transition into clinical trials, as well as costs that are not allocable to a clinical development program, such as unallocated manufacturing infrastructure costs. Because we conduct multiple research projects and utilize resources across several programs, our research and preclinical development costs are not directly assigned to individual programs.

          For purposes of reimbursement from our collaboration partners, we capture the level of effort expended on a program through our project management system, which is based primarily on human resource time allocated to each program, supplemented by an allocation of indirect costs and other specifically identifiable costs, if any. As a result, the costs allocated to a program do not necessarily reflect the actual costs of the program.

          We initiated clinical testing of our AIDS vaccine product candidate in December 2003 and our rheumatoid arthritis product candidate in March 2004. As a result, all related development activities associated with our cystic fibrosis, rheumatoid arthritis and AIDS vaccine programs are reflected as costs associated with programs in clinical development as of the date of initiation of clinical testing. Therefore, during 2004, we expect our research and development expenses associated with programs under clinical development to increase, reflecting the transition of these programs into clinical testing.

          General and Administrative Expenses. General and administrative expenses increased to $2.1 million for the three months ended June 30, 2004, from $1.4 million for the same period in 2003, and increased to $3.8 million for the six months ended June 30, 2004 from $2.8 million for the same period in 2003. This increase primarily reflects higher professional service costs related to patent issuances and regulatory compliance, and higher personnel costs.

          Restructure Charges. Restructure charges decreased to $221,000 for the three months ended June 30, 2004, from $2.9 million for the same period in 2003, and decreased to $416,000 for the six months ended June 30, 2004, from $3.2 million for the same period in 2003. The charge for the six months ended June 30, 2004 represents accretion expense of $270,000 due to the passage of time and results from the difference between the fair value of payments in the estimate of the accrued restructure liability compared to the actual rent payments made during the quarter and an additional charge of $146,000 due to updates to our assumptions as to rental income that may be achieved under a sublease arrangement of our Sharon Hill facility. The charges for

11


Table of Contents

the three and six months ended June 30, 2003, primarily represent changes in the restructure accrual due to significant changes in our expectations regarding market conditions and sublease assumptions.

     Other Income and Expense

          Investment Income. Investment income decreased to $21,000 for the three months ended June 30, 2004, from $56,000 for the same period in 2003. This decrease resulted from a decrease in the net yield of our cash equivalents. Investment income increased to $145,000 for the six months ended June 30, 2004, from $108,000 for the same period in 2003. This increase resulted from higher average cash balances in 2004 as a result of our financing completed in February 2004, partially offset by lower yields.

          Interest Expense. Interest expense relates to interest on outstanding loans from our collaborative partners, notes and obligations under equipment financing arrangements and installment loans we use to finance purchases of laboratory and computer equipment, furniture and leasehold improvements. Interest expense decreased to $117,000 for the three months ended June 30, 2004, from $360,000 for the same period in 2003 and decreased to $237,000 for the six months ended June 30, 2004, from $722,000 for the same period in 2003. These decreases reflects lower average principal balances as the result of our conversion of approximately $9.4 million of debt owed to Elan into shares of our common stock in September 2003.

Liquidity and Capital Resources

          Our combined cash and cash equivalents increased to $37.4 million at June 30, 2004, compared to $21.1 million at December 31, 2003. For the six months ended June 30, 2004, the principal sources of cash were $23.8 million in net proceeds from the issuance of approximately 10.9 million shares of our common stock in February 2004 and collaborative funding received from partners. Our principal use of cash was $6.9 million to fund our operations during the period.

          Our shareholders’ equity increased to $48.7 million at June 30, 2004, compared to $33.5 million at December 31, 2003. This increase includes net proceeds of $23.8 million from the February 2004 sale of our common stock and the February 2004 acquisition of the minority interest in CellExSys of $750,000, reduced by the net loss during the period of $9.3 million.

          We have financed our product development activities and general corporate functions primarily through proceeds from public and private sales of our equity securities, through cash payments received from our collaborative partners and proceeds from the issuance of debt. To a lesser degree, we have also financed our operations through interest earned on cash and cash equivalents, loan funding under equipment leasing agreements and research grants. These financing sources have historically allowed us to maintain adequate levels of cash and investments.

          Our cystic fibrosis product candidate is in a second Phase II clinical trial, our AIDS vaccine candidate is in a Phase I clinical trial and we initiated a Phase I clinical trial for our rheumatoid arthritis product candidate in March 2004. We expect to continue incurring significant expense in advancing our product candidates toward commercialization. As a result, we do not expect to generate sustained positive cash flow from our operations for at least the next several years and only then if we can successfully develop and commercialize our product candidates. We will require substantial additional financial resources to fund the development and commercialization of our product candidates and expand research and development of our product candidates for treating additional diseases.

          We expect to maintain our focus on our key development programs in cystic fibrosis, AIDS and rheumatoid arthritis in 2004. We believe that our cash needs will increase by approximately 20% during 2004 compared to 2003 to support the advancement of these clinical development programs. We expect to continue to receive financial support for specific programs to offset some of the costs of development.

          We have an ongoing collaboration with IAVI and CCRI to develop an AIDS vaccine. The term of this collaboration has been extended through December 2006. Assuming that we complete all of the planned development activities, we expect to receive up to $10.7 million in funding from IAVI to cover the costs of this program in 2004. We also have a collaboration with the CF Foundation related to our second Phase II clinical trial for our product candidate for treating cystic fibrosis. Under this collaboration, the CF Foundation is providing funding to the sites conducting this trial to cover their direct costs of the trial.

          We expect that our cash and cash equivalents at June 30, 2004, plus the funding we expected from IAVI to fund 2004 work under our AIDS vaccine collaboration, will be sufficient to fund our operations until at least the beginning of 2006. We believe that this will be sufficient time to complete each of our current clinical trials, evaluate the results, and, assuming satisfactory results, plan or initiate further clinical testing. In August 2006, our $10 million note payable to Biogen becomes due, which will require that we raise additional capital to repay the note or seek an alternative arrangement to repay the note. We also have a $650,000 loan from Biogen that becomes due in September 2005. Although our development collaboration with IAVI has been

12


Table of Contents

extended through the end of 2006, the development plan and budget under the collaboration is established on an annual basis. While we expect this program to continue through at least the duration of the current collaboration term, we have not established the work plan and budget for 2005 and 2006 with IAVI and have therefore not yet made an assumption as to the level of funding that we may receive from IAVI in those years.

     We expect the level of our future operating expenses to be driven by the needs of our product development programs, offset by the availability of funds through partner-funded collaborations, equity offerings or other financing activities. The size, scope and pace of our development activities depend on the availability of these resources. Our future cash requirements will depend on many factors, including:

  the rate and extent of scientific progress in our research and development programs;
 
  the timing, costs and scope of, and our success in, clinical trials, obtaining regulatory approvals and filing, prosecuting and enforcing patents;
 
  competing technological and market developments;
 
  the timing and costs of, and our success in, any product commercialization activities and facility expansions, if and as required; and
 
  the expense and outcome of any litigation or administrative proceedings involving our intellectual property, or access to third-party intellectual property through licensing agreements.

     IAVI has the right to terminate our collaboration and its obligation to provide research funding at any time for any reason with 90 days’ notice. If we were to lose the collaborative funding expected from IAVI and were unable to obtain alternative sources of funding for the AIDS vaccine product candidate, we may be unable to continue our research and development program for that product candidate. The CF Foundation has the right to terminate our funding agreement at any time for any reason.

     We are seeking partners for our hemophilia and cancer programs and evaluating other opportunities to obtain additional capital to fund our future operations. Additional sources of financing could involve one or more of the following:

  entering into additional product development and funding collaborations or other strategic transactions, or extending or expanding our current collaborations;
 
  selling or licensing our technology or product candidates;
 
  borrowing under loan or equipment leasing arrangements;
 
  issuing equity in the public or private markets; or
 
  issuing debt.

     Additional funding may not be available to us on reasonable terms, if at all. Depending on our ability to successfully access additional funding, we may be forced to implement significant cost reduction measures. These adjustments may include scaling back, delaying or terminating one or more research and development programs, curtailing capital expenditures or reducing other operating activities. We may also be required to relinquish some rights to our technology or product candidates or grant licenses on unfavorable terms, either of which would reduce the ultimate value to us of the technology or product candidates.

Factors Affecting Our Operating Results, Our Business and Our Stock Price

     In addition to the other information contained in this quarterly report, you should carefully read and consider the following risk factors. If any of these risks actually occur, our business, operating results or financial condition could be harmed. This could cause the trading price of our stock to decline, and you could lose all or part of your investment.

Risks Related to Our Business

We expect to continue to operate at a loss and may never become profitable.

     Substantially all of our revenue has been derived under collaborative research and development agreements relating to the development of our potential product candidates. We have incurred, and will continue to incur for the foreseeable future, significant expense to develop our research and development programs, conduct preclinical studies and clinical trials, seek regulatory approval for our product candidates and provide general and administrative support for these activities. As a result, we have incurred significant net losses since inception, and we expect to continue to incur substantial additional losses in the future. As of June 30, 2004, we had an accumulated deficit of approximately $226 million. We may never generate profits and, if we do become profitable, we may be unable to sustain or increase profitability.

All of our product candidates are in early-stage clinical trials or preclinical development, and if we are unable to successfully develop and commercialize our product candidates we will be unable to generate sufficient capital to maintain our business.

     In July 2003, we initiated a confirmatory Phase II clinical trial for our cystic fibrosis product candidate in the United States. In December 2003, we initiated a Phase I trial for our AIDS vaccine product candidate in Europe. In March 2004, we initiated a Phase I trial for our rheumatoid arthritis product candidate in the United States and Canada. Our product candidates for cancer have been evaluated in Phase I and Phase II clinical trials. We will not generate any product revenue for at least several years and then only if we can successfully develop and commercialize our product candidates. Commercializing our potential products depends on successful completion of additional research and development and testing, in both preclinical development and clinical trials. Clinical trials may take several years or more to complete. The commencement, cost and rate of completion of our clinical trials may vary or be delayed for many reasons, including the risks discussed elsewhere in this section. If we are unable to successfully complete preclinical and clinical development of some or all of our product candidates in a timely manner, we may be unable to generate sufficient product revenue to maintain our business.

     Even if our potential products succeed in clinical trials and are approved for marketing, these products may never achieve market acceptance. If we are unsuccessful in commercializing our product candidates for any reason, including greater effectiveness or economic feasibility of competing products or treatments, the failure of the medical community or the public to accept or use any products based on gene delivery, inadequate marketing and distribution capabilities or other reasons discussed elsewhere in this section, we will be unable to generate sufficient product revenue to maintain our business.

If we are unable to raise additional capital when needed, we will be unable to conduct our operations and develop our potential products.

     Because internally generated cash flow will not fund development and commercialization of our product candidates, we will require substantial additional financial resources. Our future capital requirements will depend on many factors, including:

  the rate and extent of scientific progress in our research and development programs;
 
  the timing, costs and scope of, and our success in, conducting clinical trials, obtaining regulatory approvals and pursuing patent prosecutions;
 
  competing technological and market developments;
 
  the timing and costs of, and our success in, any commercialization activities and facility expansions, if and as required; and
 
  the existence and/or outcome of any litigation or administrative proceedings involving intellectual property.

     As of June 30, 2004, we had approximately $37.4 million in cash and cash equivalents. We expect that our cash resources at June 30, 2004 and the funding expected from IAVI to fund 2004 work under our AIDS vaccine collaboration will be sufficient to fund our operations until at least the beginning of 2006. We are evaluating opportunities to obtain additional capital to fund our operations beyond that time. Additional sources of financing could involve one or more of the following:

14


Table of Contents

  extending or expanding our current collaborations;
 
  entering into additional product development collaborations;
 
  selling or licensing our technology or product candidates;
 
  borrowing under loan or equipment leasing arrangements;
 
  issuing equity in the public or private markets; or
 
  issuing debt.

     Additional funding may not be available to us on reasonable terms, if at all.

     The funding that we expect to receive from IAVI depends on continued scientific progress under the collaboration and IAVI’s ability and willingness to continue or extend the collaboration. If we are unable to successfully access additional capital, we may need to scale back, delay or terminate one or more of our key development programs, curtail capital expenditures or reduce other operating activities. We may also be required to relinquish some rights to our technology or product candidates or grant or take licenses on unfavorable terms, either of which would reduce the ultimate value to us of our technology or product candidates.

The regulatory approval process for our product candidates is costly, time-consuming and subject to unpredictable changes and delays, and our product candidates may never receive regulatory approval.

     To our knowledge, no gene therapy products have received regulatory approval for marketing from the U.S. Food and Drug Administration, or FDA. Because our product candidates involve new and unproven technologies, we believe that the regulatory approval process may proceed more slowly compared to clinical trials involving traditional drugs. The FDA and applicable state and foreign regulators must conclude at each stage of clinical testing that our clinical data suggest acceptable levels of safety in order for us to proceed to the next stage of clinical trials. In addition, gene therapy clinical trials conducted at institutions that receive funding for recombinant DNA research from the U.S. National Institutes of Health, or NIH, are subject to review by the NIH’s Office of Biotechnology Activities Recombinant DNA Advisory Committee, or RAC. Although NIH guidelines do not have regulatory status, the RAC review process can impede the initiation of the trial, even if the FDA has reviewed the trial and approved its initiation. Moreover, before a clinical trial can begin at an NIH-funded institution, that institution’s Institutional Biosafety Committee must review the proposed clinical trial to assess the safety of the trial.

     The regulatory process for our product candidates is costly, time-consuming and subject to unpredictable delays. The clinical trial requirements of the FDA, NIH and other agencies and the criteria these regulators use to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty and intended use of the potential products. In addition, regulatory requirements governing gene and cell therapy products have changed frequently and may change in the future. Accordingly, we cannot predict how long it will take or how much it will cost to obtain regulatory approvals for clinical trials or for manufacturing or marketing our potential products. Some or all of our product candidates may never receive regulatory approval. A product candidate that appears promising at an early stage of research or development may not result in a commercially successful product. Our clinical trials may fail to demonstrate the safety and efficacy of a product candidate or a product candidate may generate unacceptable side affects or other problems during or after clinical trials. Should this occur, we may have to delay or discontinue development of the product candidate, and the corporate partner that supports development of that product candidate may terminate its support. Delay or failure to obtain, or unexpected costs in obtaining, the regulatory approval necessary to bring a potential product to market could decrease our ability to generate sufficient product revenue to maintain our business.

If we are unable to obtain or maintain licenses for necessary third-party technology on acceptable terms or to develop alternative technology, we may be unable to develop and commercialize our product candidates.

     We have entered into exclusive and nonexclusive license agreements that give us and our partners rights to use technologies owned or licensed by commercial and academic organizations in the research, development and commercialization of our potential products. For example, we have a gene transfer technology license agreement with Amgen Inc., or Amgen, as the successor to Immunex Corporation, or Immunex, under which we have license rights to certain Immunex proprietary technology specifically applicable to gene therapy applications. In a February 2004 letter, Amgen took the position that we are not licensed, either exclusively or non-exclusively, to use Immunex intellectual property covering TNFR:Fc or therapeutic uses for TNFR:Fc. We have responded with a letter confirming our confidence that the gene transfer technology license agreement provides us with an exclusive worldwide license to use the gene construct coding for TNFR:Fc for gene therapy applications. We have had and expect to have further communications with Amgen regarding our differences. Notwithstanding our confidence, it is possible that

15


Table of Contents

a resolution of those differences, through litigation or otherwise, could cause delay or discontinuation of our development of tgAAC94 or our inability to commercialize any resulting product.

     We believe that we will need to obtain additional licenses to use patents and unpatented technology owned or licensed by others for use, compositions, methods, processes to manufacture compositions, processes to manufacture and purify gene delivery product candidates and other technologies and processes for our present and potential product candidates. If we are unable to maintain our current licenses for third-party technology or obtain additional licenses on acceptable terms, we may be required to expend significant time and resources to develop or license replacement technology. If we are unable to do so, we may be unable to develop or commercialize the affected product candidates. In addition, the license agreements for technology for which we hold exclusive licenses typically contain provisions that require us to meet minimum development milestones in order to maintain the license on an exclusive basis for some or all fields of the license. We also have license agreements for some of our technologies, which may require us to sublicense certain of our rights. If we do not meet these requirements, our licensor may convert all or a portion of the license to a nonexclusive license or, in some cases, terminate the license.

     In many cases, patent prosecution of our licensed technology is controlled solely by the licensor. If our licensors fail to obtain and maintain patent or other protection for the proprietary intellectual property we license from them, we could lose our rights to the intellectual property or our exclusivity with respect to those rights, and our competitors could market competing products using the intellectual property. Licensing of intellectual property is of critical importance to our business and involves complex legal, business and scientific issues and is complicated by the rapid pace of scientific discovery in our industry. Disputes may arise regarding intellectual property subject to a licensing agreement, including:

  the scope of rights granted under the license agreement and other interpretation-related issues;
 
  the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;
 
  the sublicensing of patent and other rights under our collaborative development relationships;
 
  the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; and
 
  the priority of invention of patented technology.

     If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

Failure to recruit patients could delay or prevent clinical trials of our potential products, which could delay or prevent the development of potential products.

     Identifying and qualifying patients to participate in clinical trials of our potential products is critically important to our success. The timing of our clinical trials depends on the speed at which we can recruit patients to participate in testing our product candidates. We have experienced delays in some of our clinical trials, and we may experience similar delays in the future. If patients are unwilling to participate in our gene therapy trials because of negative publicity from adverse events in the biotechnology or gene therapy industries or for other reasons, including competitive clinical trials for similar patient populations, the timeline for recruiting patients, conducting trials and obtaining regulatory approval of potential products will be delayed. These delays could result in increased costs, delays in advancing our product development, delays in testing the effectiveness of our technology or termination of the clinical trials altogether.

Litigation involving intellectual property, product liability or other claims and product recalls could strain our resources, subject us to significant liability, damage our reputation or result in the invalidation of our proprietary rights.

     As our product development efforts progress, especially in potentially significant markets such as AIDS or rheumatoid arthritis therapies, the risk increases that others may claim that our processes and potential products infringe on their intellectual property rights. In addition, administrative proceedings, litigation or both may be necessary to enforce our intellectual property rights or determine the rights of others. Defending or pursuing these claims, regardless of their merit, would be costly and would likely divert management’s attention and resources away from our operations. If there were to be an adverse outcome in litigation or an interference proceeding, we could face potential liability for significant damages or be required to obtain a license to the patented process or technology at issue, or both. If we are unable to obtain a license on acceptable terms, or to develop or obtain alternative technology or processes, we may be unable to manufacture or market any product or potential product that uses the affected process or technology.

16


Table of Contents

     Clinical trials and the marketing of any potential products may expose us to liability claims resulting from the testing or use of our products. Gene therapy treatments are new and unproven, and potential known and unknown side effects of gene therapy may be serious and potentially life-threatening. Product liability claims may be made by clinical trial participants, consumers, healthcare providers or other sellers or users of our products. Although we currently maintain liability insurance, the costs of product liability and other claims against us may exceed our insurance coverage. In addition, we may require increased liability coverage as additional product candidates are used in clinical trials and commercialized. Liability insurance is expensive and may not continue to be available on acceptable terms. A product liability or other claim or product recall not covered by or exceeding our insurance coverage could significantly harm our financial condition. In addition, adverse publicity resulting from a product recall or a liability claim against us, one of our partners or another gene therapy company could significantly harm our reputation and make it more difficult to obtain the funding and collaborative partnerships necessary to maintain our business.

If we lose IAVI as a partner, we may be unable to develop our AIDS vaccine product candidate.

     We have a collaborative development agreement with IAVI, which expires in December 2006, that we expect to provide us with funding to reimburse research and development and manufacturing expenses we incur in connection with the collaboration. In addition, our collaboration with IAVI provides funding for the Phase I clinical trial for our AIDS vaccine product candidate. A significant portion of our operating and clinical trial expenses are funded through our collaborative agreements with IAVI.

     IAVI has the right to terminate the collaboration or its obligation to provide funding at any time for any reason with 90 days’ notice, which would significantly affect our operating activities. The loss of significant amounts of collaborative or clinical trial funding could cause the delay, reduction or termination of the related research and development programs, and a reduction in capital expenditures and other operating activities necessary to support general operations. Such a reduction could further impede our ability to develop our product candidates.

If we do not attract and retain qualified personnel, we may be unable to develop and commercialize some of our potential products.

     Our future success depends in large part on our ability to attract and retain key technical and management personnel. All of our employees, including our executive officers, can terminate their employment with us at any time. We have programs in place designed to retain personnel, including competitive compensation packages and programs to create a positive work environment. Other companies, research and academic institutions and other organizations in our field compete intensely for employees, however, and we may be unable to retain our existing personnel or attract additional qualified employees and consultants. If we experience significant turnover or difficulty in recruiting new personnel, our research and development of product candidates could be delayed and we could experience difficulty in generating sufficient revenue to maintain our business.

If our partners or scientific consultants terminate, reduce or delay our relationships with them, we may be unable to develop our potential products.

     Our partners provide funding, manage regulatory filings, aid and augment our internal research and development efforts and provide access to important intellectual property and know-how. Their activities include, for example, support in processing the regulatory filings of our product candidates and funding clinical trials. Our outside scientific consultants and contractors perform research, develop technology and processes to advance and augment our internal efforts and provide access to important intellectual property and know-how. Their activities include, for example, clinical evaluation of our product candidates, product development activities performed under our research collaborations, research under sponsored research agreements and contract manufacturing services. Collaborations with established pharmaceutical and biotechnology companies and academic, research and public health organizations often provide a measure of validation of our product development efforts in the eyes of securities analysts, investors and the medical community. The development of certain of our potential products, and therefore the success of our business, depends on the performance of our partners, consultants and contractors. If they do not dedicate sufficient time, regulatory or other technical resources to the research and development programs for our product candidates or if they do not perform their obligations as expected, we may experience delays in, and may be unable to continue, the preclinical or clinical development of those product candidates. Each of our collaborations and scientific consulting relationships concludes at the end of the term specified in the applicable agreement unless we and our partners agree to extend the relationship. Any of our partners may decline to extend the collaboration, or may be willing to extend the collaboration only with a significantly reduced scope, for a number of scientific or business reasons. Competition for scientific consultants and partners in gene therapy is intense. We may be unable to successfully maintain our existing relationships or establish additional relationships necessary for the development of our product candidates on acceptable terms, if at all. If we are unable to do so, our research and development programs may be delayed or we may lose access to important intellectual property or know-how.

The success of our clinical trials and preclinical studies may not be indicative of results in a large number of patients of either safety or efficacy.

     The successful results of our technology in preclinical studies using animal models may not be predictive of the results that we will see in our clinical trials. In addition, results in early-stage clinical trials are based on limited numbers of patients and generally test for drug safety rather than efficacy. Our reported progress and results from our early phases of clinical testing of our product candidates may not be indicative of progress or results that will be achieved from larger populations, which could be less favorable. Moreover, we do not know if the favorable results we have achieved in clinical trials will have a lasting effect. If a larger group of patients does not experience positive results, or if any favorable results do not demonstrate a beneficial effect, our product candidate for cystic fibrosis, or any other potential products that we advance to clinical trials, may not receive approval from the FDA for further clinical trials or commercialization.

We may be unable to adequately protect our proprietary rights domestically or overseas, which may limit our ability to successfully market any product candidates.

     Our success depends substantially on our ability to protect our proprietary rights and operate without infringing on the proprietary rights of others. We own or license patents and patent applications, and will need to license additional patents, for genes, processes, practices and techniques critical to our present and potential product candidates. If we fail to obtain and maintain patent or other intellectual property protection for this technology, our competitors could market competing products using those genes, processes, practices and techniques. The patent process takes several years and involves considerable expense. In addition, patent applications and patent positions in the field of biotechnology are highly uncertain and involve complex legal, scientific and factual questions. Our patent applications may not result in issued patents and the scope of any patent may be reduced both before and after the patent is issued. Even if we secure a patent, the patent may not provide significant protection and may be circumvented or invalidated.

     We also rely on unpatented proprietary technology and technology that we have licensed on a nonexclusive basis. While we take precautions to protect our proprietary unpatented technology, we may be unable to meaningfully protect this technology from unauthorized use or misappropriation by a third party. Our competitors could also obtain rights to our nonexclusively licensed proprietary technology. In any event, other companies may independently develop equivalent proprietary information and techniques. If our competitors develop and market competing products using our unpatented or nonexclusively licensed proprietary technology or substantially similar technology, our products, if successfully developed, could suffer a reduction in sales or be forced out of the market.

If we do not develop adequate manufacturing, sales, marketing and distribution capabilities, either alone or with our business partners, we will be unable to generate sufficient product revenue to maintain our business.

     We currently do not have the physical capacity to manufacture large-scale quantities of our potential products. This could limit our ability to conduct large clinical trials of a product candidate and to commercially launch a successful product candidate. In order to manufacture product at such scale, we will need to expand or improve our current facilities and staff or supplement them through the use of contract providers. If we are unable to obtain and maintain the necessary manufacturing capabilities, either alone or through third parties, we will be unable to manufacture our potential products in quantities sufficient to sustain our business. Moreover, we are unlikely to become profitable if we, or our contract providers, are unable to manufacture our potential products in a cost-effective manner.

     In addition, we have no experience in sales, marketing and distribution. To successfully commercialize any products that may result from our development programs, we will need to develop these capabilities, either on our own or with others. We intend to enter into collaborations with other entities to utilize their mature marketing and distribution capabilities, but we may be unable to enter into marketing and distribution agreements on favorable terms, if at all. If our current or future collaborative partners do not commit sufficient resources to timely marketing and distributing our future products, if any, and we are unable to develop the necessary marketing and distribution capabilities on our own, we will be unable to generate sufficient product revenue to sustain our business.

Table of Contents

Post-approval manufacturing or product problems or failure to satisfy applicable regulatory requirements could prevent or limit our ability to market our products.

     Commercialization of any products will require continued compliance with FDA and other federal, state and local regulations. For example, our current manufacturing facility, which is designed for manufacturing our AAV vectors for clinical and development purposes, is subject to the Good Manufacturing Practices requirements and other regulations of the FDA, as well as to other federal, state and local regulations such as the Occupational Health and Safety Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act and the Environmental Protection Act. Any future manufacturing facilities that we may construct for large-scale commercial production will also be subject to regulation. We may be unable to obtain regulatory approval for or maintain in operation this or any other manufacturing facility. In addition, we may be unable to attain or maintain compliance with current or future regulations relating to manufacture, safety, handling, storage, record keeping or marketing of potential products. If we fail to comply with applicable regulatory requirements or discover previously unknown manufacturing, contamination, product side effects or other problems after we receive regulatory approval for a potential product, we may suffer restrictions on our ability to market the product or be required to withdraw the product from the market.

Risks Related to Our Industry

Adverse events in the field of gene therapy could damage public perception of our potential products and negatively affect governmental approval and regulation.

     Public perception of our product candidates could be harmed by negative events in the field of gene therapy. For example, in late 2002, two patients in a French academic clinical trial being treated for x-linked severe combined immunodeficiency in a gene therapy trial using a retroviral vector developed leukemia. Patient deaths, related and unrelated to gene therapy, have occurred in other clinical trials. These adverse events and the resulting publicity, as well as any other adverse events in the field of gene therapy that may occur in the future, could result in a decrease in demand for any products that we may develop. The commercial success of our product candidates will depend in part on public acceptance of the use of gene therapy for preventing or treating human diseases. If public perception is influenced by claims that gene therapy is unsafe, our product candidates may not be accepted by the general public or the medical community. The public and the medical community may conclude that our technology is unsafe.

     Future adverse events in gene therapy or the biotechnology industry could also result in greater governmental regulation, unfavorable public perception, stricter labeling requirements and potential regulatory delays in the testing or approval of our potential products. Any increased scrutiny could delay or increase the costs of our product development efforts or clinical trials.

Our use of hazardous materials exposes us to liability risks and regulatory limitations on their use, either of which could reduce our ability to generate product revenue.

     Our research and development activities involve the controlled use of hazardous materials, including chemicals, biological materials and radioactive compounds. Our safety procedures for handling, storing and disposing of these materials must comply with federal, state and local laws and regulations, including, among others, those relating to solid and hazardous waste management, biohazard material handling, radiation and air pollution control. We may be required to incur significant costs in the future to comply with environmental or other applicable laws and regulations. In addition, we cannot eliminate the risk of accidental contamination or injury from hazardous materials. If a hazardous material accident were to occur, we could be held liable for any resulting damages, and this liability could exceed our financial resources. Accidents unrelated to our operations could cause federal, state or local regulatory agencies to restrict our access to hazardous materials needed in our research and development efforts, which could result in delays in our research and development programs. Paying damages or experiencing delays caused by restricted access could reduce our ability to generate revenue and make it more difficult to fund our operations.

The intense competition and rapid technological change in our market may result in pricing pressures and failure of our potential products to achieve market acceptance.

     We face increasingly intense competition from a number of commercial entities and institutions that are developing gene therapy and cell therapy technologies. Our competitors include early-stage and more established gene delivery companies, other biotechnology companies, pharmaceutical companies, universities, research institutions and government agencies developing gene therapy products or other biotechnology-based therapies designed to treat the diseases on which we focus. We also face competition from companies using more traditional approaches to treating human diseases, such as surgery, medical devices and pharmaceutical products. As our product candidates become commercial gene therapy products that may affect commercial markets of the analogous protein or traditional pharmaceutical therapy, disputes including lawsuits, demands, threats or patent challenges may arise in an effort to slow our development. In addition, we compete with other companies to acquire products or technology from research institutions or universities. Many of our competitors have substantially more financial and

19


Table of Contents

infrastructure resources and larger research and development staffs than we do. Many of our competitors also have greater experience and capabilities than we do in:

  research and development;
 
  clinical trials;
 
  obtaining FDA and other regulatory approvals;
 
  manufacturing; and
 
  marketing and distribution.

     In addition, the competitive positions of other companies, institutions and organizations, including smaller competitors, may be strengthened through collaborative relationships. Consequently, our competitors may be able to develop, obtain patent protection for, obtain regulatory approval for, or commercialize new products more rapidly than we do, or manufacture and market competitive products more successfully than we do. This could limit the prices we could charge for the products that we are able to market or result in our products failing to achieve market acceptance.

     Gene therapy is a rapidly evolving field and is expected to continue to undergo significant and rapid technological change and competition. Rapid technological development by our competitors, including development of technologies, products or processes that are more effective or more economically feasible than those we have developed, could result in our actual and proposed technologies, products or processes losing market share or becoming obsolete.

Healthcare reform measures and the unwillingness of third-party payors to provide adequate reimbursement for the cost of our products could impair our ability to successfully commercialize our potential products and become profitable.

     Sales of medical products and treatments depends substantially, both domestically and abroad, on the availability of reimbursement to the consumer from third-party payors. Our potential products may not be considered cost-effective by third-party payors, who may not provide coverage at the price set for our products, if at all. If purchasers or users of our products are unable to obtain adequate reimbursement, they may forego or reduce their use of our products. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realize a sufficient return on our investment.

     Increasing efforts by governmental and third-party payors, such as Medicare, private insurance plans and managed care organizations, to cap or reduce healthcare costs will affect our ability to commercialize our product candidates and become profitable. We believe that third-party payors will attempt to reduce healthcare costs by limiting both coverage and level of reimbursement for new products approved by the FDA. There have been and will continue to be a number of federal and state proposals to implement government controls on pricing, the adoption of which could affect our ability to successfully commercialize our product candidates. Even if the government does not adopt any such proposals or reforms, their announcement could impair our ability to raise capital.

Risks Related to Our Common Stock

Concentration of ownership of our common stock may give certain shareholders significant influence over our business.

     A small number of investors own a significant number of shares of our common stock. As of June 30, 2004, Biogen and Elan and its affiliates each held approximately 12.1 million shares of our common stock, or 14.9% of our current common shares outstanding. This concentration of stock ownership may allow these shareholders to exercise significant control over our strategic decisions and block, delay or substantially influence all matters requiring shareholder approval, such as:

  election of directors;
 
  amendment of our charter documents; or
 
  approval of significant corporate transactions, such as a change of control of Targeted Genetics.

20


Table of Contents

     The interests of these shareholders may conflict with the interests of other holders of our common stock with regard to such matters. Furthermore, this concentration of ownership of our common stock could allow these shareholders to delay, deter or prevent a third party from acquiring control of Targeted Genetics at a premium over the then-current market price of our common stock, which could result in a decrease in our stock price.

Market fluctuations or volatility could cause the market price of our common stock to decline and limit our ability to raise capital.

     The stock market in general and the market for biotechnology-related companies in particular have experienced extreme price and volume fluctuations, often unrelated to the operating performance of the affected companies. The market price of the securities of biotechnology companies, particularly companies such as ours without earnings and product revenue, has been highly volatile and is likely to remain so in the future. Any report of clinical trial results that are below the expectations of financial analysts or investors could result in a decline in our stock price. We believe that in the past, similar levels of volatility have contributed to the decline in the market price of our common stock, and may do so again in the future. Trading volumes of our common stock can increase dramatically, resulting in a volatile market price for our common stock. In addition, the trading price of our common stock could decline significantly as a result of sales of a substantial number of shares of our common stock, or the perception that significant sales could occur.

     For example, on March 31, 2004, we and Elan entered into a termination agreement that permits Elan to sell shares of our common stock, subject to certain exceptions, under the trading volume limitations of Rule 144(e)(1) promulgated under the Securities Act of 1933, as amended. The trading volume limitations on Elan are reduced over time subject to the terms of the termination agreement. In addition, Elan has registration rights with respect to its holdings pursuant to a registration rights agreement dated July 21, 1999. Both the termination agreement and the registration rights agreement permit Elan to sell quantities of stock, which could adversely impact the price of our common stock.

     In the past, securities class action litigation has been brought against companies that experience volatility in the market price of their securities. Market fluctuations in the price of our common stock could also adversely affect our collaborative opportunities and our future ability to sell equity securities at a price we deem appropriate. As a result, you could lose all or part of your investment.

Our future capital-raising activities will likely involve the issuance of equity securities, which will dilute your investment and could result in a decline in the trading price of our common stock.

     Since June 1, 2003, we have issued 18.6 million shares of our common stock in equity financings that have been priced at a discount to the then-current market price of our common stock. These financings were completed in order to fund our research and development programs and for other general corporate purposes. To meet all or a portion of our future funding requirements, we will likely sell additional securities in the public or private equity markets if and when conditions are favorable, even if we do not have an immediate need for additional capital at that time. Raising funds through the issuance of equity securities will dilute the ownership of our existing shareholders. Furthermore, we may enter into financing transactions at prices that represent a substantial discount to market price. A negative reaction by investors and securities analysts to any discounted sale of our equity securities could result in a decline in the trading price of our common stock.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     Cash and cash equivalents. Because of the short-term nature of our investments, we believe that our exposure to market rate fluctuations on those investments is minimal. Currently, we do not use any derivative or other financial instruments or derivative commodity instruments to hedge any market risks and do not plan to employ these instruments in the future. At June 30, 2004, we held $37.4 million in cash and cash equivalents, which are primarily invested in a money market fund that invests in securities that, on the average, mature in less than 60 days and a short-term bond fund that invests in securities that, on the average, mature in less than 12 months. An analysis of the impact on these securities of a hypothetical 10% change in short-term interest rates from those in effect at June 30, 2004, indicates that such a change in interest rates would not have a significant impact on our financial position or on our expected results of operations in 2004.

     Notes payable. Our results of operations are affected by changes in short-term interest rates as a result of a loan from Biogen that contains a variable interest rate. Interest payments on this loan are determined by the LIBOR plus a margin of 1%. The carrying amounts of the notes payable and equipment financing arrangements approximate fair value because the interest rates on these instruments change with, or approximate, market rates. The following table provides information as of June 30, 2004, about our obligations that are sensitive to changes in interest rate fluctuations:
