SELLING SECURITYHOLDERS The following table provides information regarding the principal amount of notes beneficially owned by certain of our selling securityholders, the percentage of outstanding notes held by each selling securityholder, the number of shares of our common stock beneficially owned by each selling securityholder, the number of shares of our common stock each selling securityholder would beneficially own upon conversion of its entire principal amount of notes and the percentage of our outstanding common stock held by each selling securityholder. The table below supplements or amends the table of securityholders contained on pages 2 through 5 of the prospectus supplement dated December 13, 2002, which superseded the table of securityholders contained in the prospectus and our previous prospectus supplements filed prior to December 13, 2002. Where the name of a selling securityholder identified in the table below also appears in the table in the prospectus or in the previous prospectus supplements, the information set forth in the table below regarding that selling securityholder supersedes the information in the prospectus or in the previous prospectus supplements. This information was furnished to us by the selling securityholders listed below on or before December 29, 2003. Because selling securityholders may trade all or some of the notes listed at any time without notifying us, the table below may not reflect the exact value of notes held by each selling securityholder on the date of this supplement. The date of this prospectus supplement is December 31, 2003.

(4) Assumes conversion of all of the selling securityholder's notes at a conversion rate of 17.763 per note and a cash payment in lieu of the issuance of any fractional share interest. However, this conversion rate is subject to adjustment as described under "Description of the Notes -- Conversion Rights." As a result, the number of shares of common stock issuable upon conversion of the notes may increase or decrease in the future. (5) Reflects rounding down of fractional shares of common stock issuable to each selling securityholder upon conversion of the notes. (6) Calculated based on Rule 13d-3 of the Securities Exchange Act of 1934 using 42,691,244 shares of common stock outstanding as of December 12, 2002.
