(1)   For the purposes herein, the shares “beneficially owned” by each of the selling stockholders reflects the maximum number of shares of common stock which may be beneficially owned by each of the selling stockholders (other than Alloy Ventures 2002, L.P. and Alloy Partners 2002, L.P. (collectively, the “Alloy Entities”)) after proposed distributions of such shares by the Alloy Entities to their limited partners (the “Proposed Distribution”). Each distribution to such limited partners will result in the Alloy Entities’ aggregate beneficial ownership decreasing by an amount equal to such distribution. The beneficial ownership of the Alloy Entities includes warrants to purchase up to 1,748,684 shares of common stock that are exercisable within 60 days of May 23, 2003.
 
(2)   For the purposes herein, the number of shares of common stock offered by each of the selling stockholders (other than the Alloy Entities) reflects the maximum number of shares of common stock which may be offered by each selling stockholder after the Proposed Distribution. For the Alloy Entities, the number reflects the maximum number of shares of common stock which may be offered prior to the Proposed Distribution.

Furthermore, the selling stockholders identified in the table set forth under the caption “Selling Stockholders” in the Prospectus may have sold, transferred or otherwise disposed of all or a portion of their shares of our common stock since the date on which they provided us with information regarding their common stock ownership. We have not made any independent inquiries as to the foregoing.

This Prospectus Supplement provides specific information about the offering of common stock under the Registration Statement, and updates information provided in the Prospectus. You should read both this Prospectus Supplement and the Prospectus carefully.

AN INVESTMENT IN OUR SECURITIES INVOLVES SUBSTANTIAL RISKS. THESE RISKS ARE DESCRIBED UNDER THE CAPTION “RISK FACTORS” BEGINNING ON PAGE 2 OF THE PROSPECTUS.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY OTHER REGULATORY BODY HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS SUPPLEMENT OR THE PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
