Item 5.  Interest in Securities of the Issuer.
         ------------------------------------

         (a)    NEA 10 is the record owner of the Record Shares. As the sole
                general partner of NEA 10, NEA Partners 10 may be deemed to own
                beneficially the Record Shares. As the individual general
                partners of NEA Partners 10, each of the General Partners also
                may be deemed to own beneficially the Record Shares.

                NEA 10 holds warrants to purchase the Warrant Shares which
                warrants are exercisable within 60 days of December 3, 2002. As

                own beneficially 5.3% of the Record and Warrant Shares. Alsop,
                Barris, McConnell and Perry may be deemed to own beneficially
                5.4% of the Record and Warrant Shares. These percentages are
                calculated based upon 48,792,631 Shares reported to be
                outstanding in the Issuer's most recent Quarterly Report on Form
                10-Q, as adjusted to reflect the issuance of 6,963,788 shares of

                The working capital of NEA 10 was the source of the funds for
                the purchase. No part of the purchase price paid by NEA 10 was
                represented by funds or other consideration borrowed or
                otherwise obtained for the purpose of acquiring, holding,
                trading or voting the Record Shares. In connection with the
                purchase of the Common Stock, NEA 10 also received a three year
                warrant to purchase 732,950 shares (the "Three Year Warrant
                Shares") of Common Stock which warrant is presently immediately
                exercisable. In connection with the purchase of the Common
                Stock, NEA 10 also received a four year warrant to purchase
