Biotechnology Value Fund Urges Stockholders to Remove and Replace Current Board of Avigen, Inc. in an Effort to Protect and Maxi

NEW YORK, March 12  /PRNewswire/ -- Biotechnology Value Fund, L.P. ("BVF"), today announced that it has sent a letter to the stockholders of Avigen, Inc.

BVF, the beneficial owner of approximately 30% of the Company's outstanding common stock, has called the Special Meeting to give stockholders the opportunity to protect what remains of Avigen's assets, which it believes are in danger of being completely wasted by the Board.

ELECT DIRECTORS WHO ARE DEDICATED TO MAXIMIZING VALUE FOR ALL AVIGEN STOCKHOLDERS BY REDUCING CORPORATE WASTE AND PROTECTING STOCKHOLDERS' DOWNSIDE RISK WHILE MAINTAINING SIGNIFICANT UPSIDE POTENTIAL

Dear Fellow Stockholders:

SAN FRANCISCO - March 12, 2009 - We, the Biotechnology Value Fund ("BVF"), are the owners of 8,819,600 shares, or approximately 30% of Avigen's outstanding common stock. Since we took the lead in protecting value for all stockholders of Avigen in October of 2008, the stock price has increased by over 65%. We have successfully caused the Avigen management team and Board to reduce expenses and sell off programs that they do not have the necessary expertise to develop. We now need your participation to secure Avigen's substantial remaining value by removing the members of the current self-serving Board and electing our independent nominees who are committed to protecting value for all stockholders.

Let me state from the outset that we neither seek, nor would we accept, any consideration or benefit solely for ourselves. Avigen has falsely accused us of this numerous times, even though we have been crystal clear on this fundamental issue all along. We are waging this effort because (a) we feel a sense of responsibility to do so on behalf of all stockholders given our unique position as the largest stockholder and (b) we believe it is the right thing to do, especially in the context of the current economic environment caused, in part, by similar self-serving managements and Boards.

  Throughout this process we have sought only three simple things:
  1. that Avigen stop recklessly wasting stockholder money;
  2. that stockholders be empowered to decide the fate of Avigen's remaining
     cash; and
  3. that stockholders be guaranteed a quantified worst-case outcome of
     approximately Avigen's liquidation value.




Thus far we have made progress with #1 and #2 above. Facing pressure from BVF, Avigen has abandoned, at least temporarily, its plan to spend money on its remaining products. In addition, the Company has now been forced to call a special meeting to finally permit stockholders the opportunity to weigh in. Prior to our intervention, Avigen's stock traded at a mere 33% of the cash in the bank and at a steep discount to its current price. This is a remarkable reflection on how poorly Avigen was and is viewed by the investment community. Prior to our intervention, Avigen's plan was to spend all stockholder money over two years on uncompelling products that it has subsequently conceded were not worthy of investment.

  It is worth reflecting on some of Avigen's historical "accomplishments":

  1. Avigen has consumed over $250 million of investor capital, with little
     value to show for it. Why should they be entrusted with the last $50
     million?
  2. Avigen selected a Chief Executive Officer who lives in Park City, Utah
     when the Company is based in California.
  3. Avigen has committed to pay significant fees in the form of golden
     parachutes to its senior executives and multiple investment bankers,
     lawyers and consultants in an amount that, we believe, could exceed $5
     million under certain circumstances.
  4. Despite purporting to have reduced their use of cash and working to
     protect stockholders, we believe Avigen will spend nearly $20 million,
     or over $0.65 per share, between the time they announced the failure of
     AV650 and when they supposedly hope to complete a merger.
  5. Avigen adopted a "poison pill," which we believe is just another
     example of the Board acting first to protect their jobs rather than the
     stockholders they have a fiduciary duty to represent.
  6. Avigen delayed calling the special meeting for approximately two months
     before setting a rushed meeting date that we believe was set to prevent
     stockholders from having adequate opportunity to receive and review
     proxy materials and vote at the special meeting.




We have grown increasingly dismayed that Avigen's Board and management team, who collectively own little stock, have wasted money on golden parachutes, multiple investment bankers, consultants and lawyers. Had Avigen merely agreed to guarantee a worst case scenario for stockholders, this fight would not have transpired. Thus, we can only conclude that Avigen is likely to gamble stockholders' remaining capital that, precedent warns, could result in a near total destruction of stockholder value.

We are frankly surprised that the Board has not previously addressed our concerns by affirmatively and unequivocally agreeing to proceed only with a transaction that provides for stockholders to receive no less than the Company's approximate liquidation value. In fact, it appears to us that the Board is only now even mentioning an undefined intent to provide some merger liquidity in response to our demand for full downside protection for all stockholders. We believe that Avigen's shares are undervalued by the market as a result of stockholders' concern about the direction the current Board is taking the Company. New leadership is needed to prevent further erosion of each stockholder's investment in Avigen, as well as to take advantage of opportunities that exist to maximize stockholder value.

Without Any Evident Rational Motive, Avigen Has Not Aggressively Pursued The COMPELLING Merger Proposal By MediciNova That Offered BOTH Downside Protection AND Significant Upside To All Avigen Stockholders

Unlike the current Board, we believe that a merger with MediciNova makes sense for all Avigen stockholders and we cannot understand why only lip service was paid to pursue a deal with MediciNova. Among the extraordinary potential benefits we see in a merger with MediciNova are:

  --  Downside Protection: Based on our analysis, even if a merger with
      MediciNova is unsuccessful, Avigen stockholders would still receive
      the approximate current liquidation value of Avigen. This means that,
      even in the worst-case scenario, the merger would yield an approximate
      65% premium to Avigen's stock price before we submitted our request to
      the Company to call the special meeting.
  --  Tremendous Upside Potential: Based on our analysis, if a merger with
      MediciNova is successful, Avigen stockholders could own a substantial
      percentage of MediciNova (approximately 45% of the combined company).
      We believe the Board has not had any substantive discussions with
      MediciNova. We do not understand why they have dismissed the offer as
      providing little value.
  --  Free Option: Under the terms of the proposed merger, stockholders
      would have at least one year after the merger is consummated to choose
      whether they want downside protection or upside potential, as
      described above. We believe this free option period offers
      stockholders tremendous upside potential with low risk.




Neither BVF nor its nominees have any financial interests in MediciNova. BVF is only interested in the superior transaction for ALL stockholders. We simply believe that in light of similar historical transactions, it is important that stockholders have downside protection. If BVF's nominees are elected to the Board, stockholders can either tender their shares in the BVF tender, or not tender and participate with BVF in the future of Avigen, whether through a merger with MediciNova, subject to the nominees' fiduciary obligations, or if the merger is not feasible, to consider liquidation or other similar type transactions. In any case all stockholders will get to choose and have the opportunity to get immediate cash back. The nominees intend to present any potential MediciNova transaction to stockholders for approval - ensuring that stockholders will get a true say in the future of Avigen.

We believe the Board's failure to commit exclusively to a transaction that offers downside protection based on the Company's liquidation value suggests that the Board is considering other options, which will put the value of Avigen at risk. As the Company's largest stockholder, we share the interest of all stockholders in protecting and preserving our investment. Unlike the directors and management, BVF only profits if the stock price goes up and shares the interest of all stockholders to increase share value and limit share loss. We receive no other payments or compensation.

The vast majority of failed biotechnology companies that have found themselves in Avigen's current situation have managed to destroy between 80%-99% of stockholder value from their then liquidation value

We are concerned that Avigen will enter into a transaction without downside protection that would end up destroying value. We have good reason to fear this, because most recent mergers involving companies similarly situated to Avigen (e.g., Transcept Pharmaceuticals, Inc., Anesiva, Inc., ARCA biopharma, Inc., Evotec Aktiengesellschaft, Cardiovascular Systems, Inc. and others), managed to destroy stockholder value. In each of these transactions, the stock prices declined over 80% from their liquidation value following the Board's decision to pursue a transaction, resulting in aggregate lost value in excess of $200 million. Of course the management, directors, and bankers took their millions of dollars of fees in cash rather than stock in the companies they supposedly supported. The directors and management of companies like Avigen deserve recognition: it is quite a feat to destroy 80% of the liquidation value of a company possessing little else but cash! The charts below illustrate these astonishing failures.

* Approximate net cash per share liquidation value at time of negative binary event.

This repeated lost value and waste is a key reason why we believe downside protection is so important for all stockholders. We want to prevent Avigen from joining this long and infamous list of failures. This is a key reason why we believe the MediciNova transaction is so attractive.

We Believe The Avigen Board Is Entrenching Itself As It Prepares To Enter Into An Egregious Transaction That Could Burn Through Our Company's Remaining Cash

In a shameless example of protecting their own self-interest, in October 2008 Avigen increased its golden parachute payments, allegedly to attract and retain executive talent. Our first question is: which executive employees does Avigen need to retain when, in our view, Avigen does not possess a viable business? We have estimated that the golden parachute payouts total at least $2 million. Payments to consultants, bankers and lawyers are quickly adding up as well. Given the current economic conditions, we find it irresponsible for Avigen to engage in such behavior that amounts to a slap in the face of all Avigen stockholders. The recent addition of a poison pill by the Board adds further insult to stockholders who have already been insulted by a Board that ignores their pleas.

We are afraid that if the current Board remains in place, they will burn through Avigen's remaining cash by engaging in a transaction that will further destroy stockholder value. For example, any transaction proposed by Avigen is likely to have a substantial and non-refundable breakup fee that will not be returned to stockholders even if a transaction is not approved. Everyday that the current Board remains in place, the cash per share is dwindling.

After Delaying the Special Meeting for Months, the Board Finally Set AN Accelerated MEETING Date to Try and Prevent Stockholders from Having an Opportunity to Let Their Voice be Heard

The Board has now set March 27, 2009 as the date for the special meeting of stockholders. We delivered our notice to the board demanding that a special meeting be called approximately two months ago. Finally, after nearly two months of delay and significant and unnecessary corporate waste, the Company announced a March 27, 2009 meeting date, which will occur in just over two weeks, barely enough time to deliver our proxy materials to you. At this critical meeting, Avigen stockholders will be given the opportunity to remove the entire Board and elect independent directors who will strive to preserve and enhance value for all Avigen stockholders. We hope that you will support us by immediately voting the enclosed GOLD proxy card. If you Share our Concern for the Future of Our Company, Do Not Delay, Vote Your Gold Proxy Card Today.
