      Common Stock that are currently issuable within 60 days of December 31,
      2002 upon the exercise of two warrants to purchase shares of Common
      Stock, one of which entitles it to purchase up to 327,980 shares of
      Common Stock and the other of which entitles the holder to purchase
      765,288 shares of Common Stock. Both warrants expire on September 29,
      2005. Pursuant to the terms of the warrants, the warrants are only
      exercisable to the extent that the number of shares of Common Stock
      issuable upon exercise of the warrants, together with any other shares
      of Common Stock beneficially owned by the Reporting Persons or any of

      would not result in the beneficial ownership of a Reporting Person or
      any of their affiliates exceeding 4.9% of the Common Stock then issued
      and outstanding.
