(1)  Assumes conversion of all of the holder's notes at a conversion ratio of
     50.6401 shares per $1,000 principal amount of notes.  However, this
     conversion ratio will be subject to further 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 49,034,316
     shares of common stock outstanding as of September 14, 2001.  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 November 8, 2001.
