          construed as an admission by any reporting person that it is a
          beneficial owner of any securities other than those directly held
          by such reporting person.

                    Under the definition of "beneficial ownership" in Rule
          13d-3 under the Securities Exchange Act of 1934, it is also
          possible that the individual general partners of Hambrecht &
          Quist Venture Partners and/or the directors and executive
          officers of Hambrecht & Quist Group might be deemed the
          "beneficial owners" of some or all of the securities to which
          this Schedule 13G relates in that they might be deemed to share
          the power to direct the voting and disposition of such
          securities.  Neither the filing of this Schedule 13G nor any of
          its contents shall be deemed to constitute an admission that any
          of such individuals is, for any purpose, the beneficial owner of
          any of the securities to which this Schedule 13G relates, and
          such beneficial ownership is expressly disclaimed.
