4. On an as converted basis, IBT owns 3,670,100 shares of Common Stock (the

which percentage is calculated based upon 50,184,407 shares of Common Stock

of Common Stock - - the number of shares of Common Stock the Reporting Persons

contractual relationship between IBT and SIML and the affiliate relationships
among SIML, Daniel, Bingham and Haas, each of SIML, Daniel, Bingham and Haas may

Bingham and Haas may be deemed to own 3,670,100 shares of Common Stock of the

deemed to own beneficially 3,670,100 shares of Common Stock. In their capacity
as members of the investment committee of Schroder Ventures Life Sciences
Advisers (UK) Limited ("SVLSAL") which advises SIML, who have authority to vote
or direct the vote of the Record Shares, Daniel and Bingham may be deemed to own
beneficially 3,670,100 shares of Common Stock. In her capacity as fund manager
of IBT, Haas may be deemed to own beneficially 3,670,100 shares of Common Stock.

3,670,100 shares which it holds of record.

          (i)  Sole power to vote or direct the vote:
               0 shares for each Reporting Person.

          (ii) Shared power to vote or direct the vote:

     Pursuant to a contractual agreement dated as of November 7, 2000, IBT has
engaged SIML to act as its discretionary investment manager. Pursuant to such
agreement, SIML manages the business and assets of IBT, which includes the
authority to make decisions regarding the acquisition or disposition of
portfolio securities by IBT and to exercise any rights (including voting rights)
with respect to such securities. IBT has the right to terminate SIML's
appointment as manager at any time if SIML commits a material breach of its
obligations under the agreement and, if its breach is capable of remedy, fails
to make good the breach within 90 days of receipt of notice from IBT requiring
it to do so. Daniel and Bingham, in their capacity as members of the investment
committee of SVLSAL which advises SIML, have the ability to direct the vote with
respect to the portfolio securities held by IBT. Haas, in her capacity as fund
