      developing, with the goal of commercializing, a new class of therapeutic
      products called gene therapeutics. We believe that a wide range of diseases
      may
      potentially be treated or prevented with gene therapeutics. In addition to
      treating diseases for which there is no treatment, we believe that there is
      a
      significant opportunity to use gene therapeutics to more effectively treat
      diseases that are currently treated using other therapeutic classes of drugs
      such as protein-based drugs, monoclonal antibodies or small molecule

      therapeutics consist of a delivery vehicle, called a vector, and genetic
      material. The role of the vector is to carry the genetic material into a target
      cell. Once delivered into the cell, the gene can express or direct production
      of
      the specific proteins encoded by the gene. Gene therapeutics may be used to
      treat disease facilitating the normal protein production or gene regulation
      capabilities of cells. Gene therapeutics may be used to enable cells to produce
      more of a certain protein or different proteins than they normally produce,
      thereby treating a disease state. Vectors can also be used to deliver specific
      sequences that once delivered and expressed as interfering RNA, or RNAi, can
      shut down or interfere with messenger RNA production of disease specific
      genes.</font></div><br>

      increased to $2.5 million for the three months ended March 31, 2008 as compared
      to $1.7 million for the same period in 2007. The increase in revenue reflects
      an
      increase in research and development and manufacturing activities under the
      NIAID-funded HIV/AIDS vaccine project in collaboration with CHOP and NCH and
      is
      partially offset by lower research and development activities under our
      collaboration with </font><font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman">IAVI</font><font style="DISPLAY: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman">.
      We
      expect that our revenue for the remainder of 2008 will consist primarily of
      research and development revenue earned from our collaboration with Celladon
      and
      the NIAID-funded HIV/AIDS subcontract with CHOP and NCH. We expect that our
      revenue for 2008 will decrease from 2007 as our partnered programs emphasize
      clinical development in 2008 which results in fewer resources devoted to the
      manufacturing aspects of development. We expect our 2008 revenue generated
      from
      our Celladon collaboration to be at approximately the same level as in 2007.
      Our
      HIV/AIDS vaccine development revenue from the IAVI and NIAID-funded projects
      fluctuates year to year depending upon the scope of development efforts underway
      within each separate but complimentary program. For 2008, our HIV/AIDS efforts
      are focused on advancing the NIAID-funded HIV/AIDS vaccine efforts. Accordingly
      we expect no levels of activity within the IAVI-funded portion of our HIV/AIDS
      development work and we expect revenue under our NIAID-funded HIV/AIDS vaccine
      collaboration to decrease compared to 2007 due to less development activity
      as
      the project will be focused primarily on clinical activities in 2008.

      scope and pace of our product development activities depend on the availability
      of these resources. Our future cash requirements will depend on many factors,

      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 and loan
      funding under equipment financing agreements. These financing sources have
      historically allowed us to maintain adequate levels of cash and cash
      equivalents.</font></div>

      development collaborations have typically provided us with funding in several
      forms, including purchases of our equity securities, loans, payments for
      reimbursement of research and development costs and milestone fees and payments.
      We and our partners typically agree on a target disease and create a development
      plan for the product candidate, which generally spans several years and is
      subject to termination or extension. For example, when the Celladon
      collaboration was initiated in 2005, it originally had a research and
      development work plan that was established and funded based on quarterly costs.
      In 2008, we and Celladon agreed to a research and development work plan
      extending through January 2010. Also, in 2005, we extended the scope of our
      IAVI-funded HIV/AIDS vaccine program activities to the developed world via
      our
      collaboration with CHOP and NCH through a subcontract with NIAID. To date we
      have received $7.0 million under this subcontract and our portion of the
      remaining project funding could be up to an additional $11.3 million over the
      remaining three years of the contract. The funding is awarded to us in annual
      installments based on an approved work plan and achievement of milestones.
      For
      2008, this program comprises substantially all of our current HIV/AIDS product
      development activities.</font></div>

      funding from each of our collaborative partners fully offsets our incremental
      program costs incurred by each collaboration and our overhead and fixed costs.
      Our revenue from collaborative agreements and licenses totaled $10.3 million
      in
      2007 and, assuming that we complete all of the planned development activities
      for each of these funded projects, we expect revenue from our collaborative
      partners of approximately $8.0 million to $9.0 million in 2008. Our revenue
      plan
      for 2008 includes the expectation that we accomplish our current Celladon heart
      failure and NIAID-funded HIV/AIDS vaccine work plans.</font></div>

      terms
      of each of our collaborations include provisions that allow our partners the
      right to terminate both the underlying collaboration and the obligation to
      provide research funding at any time with as little as 90 days notice. As an
      example, Sirna recently decided not to continue its collaboration with us on
      our
      HD program and instead we acquired the rights necessary to continue that program
      on our own. If we were to lose the collaborative funding expected from the
      Celladon collaboration or the NIAID subcontract and were unable to obtain
      alternative sources of funding, we would be unable to continue our research
      and
      development program for that product candidate and/or we would not have
      sufficient resources available to fund our operations for as long as currently
      expected.</font></div>

      near-term financing strategy includes leveraging our development capabilities
      and intellectual property assets into additional capital raising opportunities,
      advancing our clinical development programs and being able to access the public
      and private capital markets at appropriate times.&#160;Our financing strategy is
      focused around the advancement of our arthritis and heart failure programs
      in
      clinical development, the advancement of our HIV/AIDS vaccine programs, the
      HD
      program and new product development initiatives and generating value from our
      intellectual assets and capabilities. Our ability to raise capital depends
      in
      part on product development success, however, there is a low percentage of
      success in biopharmaceutical product development of all types. </font></div>

      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. 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. In addition, the sale of
      significant quantities of stock by Special Situations, Biogen Idec, OrbiMed
      Advisors LLC, Elan, or other holders of significant amounts of shares of our
      stock, could adversely impact the price of our common stock.</font></div>
