      The date of this prospectus supplement is July 7, 2004.

      The information in the table appearing under the heading "Selling

The following table sets forth certain information as of June 29, 2004, except where otherwise noted, concerning the principal amount of notes beneficially owned by each selling securityholder and the number of shares of common stock that may be offered from time to time by each selling securityholder under this prospectus. The information is based on information provided by or on behalf of the selling securityholders. The number of shares of common stock issuable upon conversion of the notes shown in the table below assumes conversion of the full amount of notes held by each holder at an initial conversion price of $10.65 per share. This conversion price is subject to adjustments in certain circumstances. Because the selling securityholders may offer all or some portion of the notes or the common stock issuable upon conversion of the notes, we have assumed for purposes of the table below that the named selling securityholders will sell all of the notes or convert all of the notes and sell all of the common stock issuable upon conversion of the notes offered by this prospectus. In addition, the selling securityholders identified below may have sold, transferred or otherwise disposed of all or a portion of their notes since the date on which they provided the information regarding their notes in transactions exempt from the registration requirements of the Securities Act. Information about the selling securityholders may change over time. Any changed information given to us by the selling securityholders will be set forth in prospectus supplements if and when necessary. 2
