(1)  Assumes conversion of all of the holder's notes at a conversion price of
     $45.7993 per share of common stock. However, this conversion price will be
     subject to adjustment as described under "Description of Notes-Conversion
     of Notes." As a result, the amount of common stock issuable upon conversion
     of the notes may increase or decrease in the future.

(2)  Calculated based on Rule 13d-3(d)(i) of the Exchange Act using 24,020,358
     shares of common stock outstanding as of April 14, 2000. In calculating
     this amount, we treated as outstanding the number of shares of common stock
     issuable upon conversion of all of that particular holder's notes. However,
     we did not assume the conversion of any other holder's notes.

     Because the selling securityholders listed above and in the prospectus
under the caption Selling Securityholders may, pursuant to the prospectus, as
supplemented, offer all or some portion of the notes, no estimate can be given
as to the amount of notes that will be held by the selling securityholders upon
termination of any such sales.

     Furthermore, the selling securityholders identified in the table set forth
in the prospectus under the caption Selling Securityholders may have sold,
transferred or otherwise disposed of all or a portion of their notes or common
stock since the date on which they provided us with information regarding their
notes or common stock, and we have not made any independent inquiries as to the
foregoing.

     Unless otherwise noted, all information provided in this prospectus
supplement is as of July 27, 2000.
