(1)   Assumes conversion of all of the selling securityholder’s notes at the conversion rate of 22.7518 shares per note. However, the conversion rate is subject to adjustment as described under “Description of the Notes — Conversion of Notes” in the accompanying prospectus. As a result, the amount of common stock issuable upon conversion of the notes may increase or decrease in the future. Assuming a conversion rate of 22.7518 shares per note, no selling securityholder will own more than 1% of our outstanding common stock upon conversion of the debentures.

(2)   All amounts have been adjusted to reflect a three-for-two stock split that occurred on February 2, 2004.

(3)   Assumes that all of the notes and/or all of the common stock into which the notes are convertible are sold. No selling securityholder will own more than 1% of our outstanding common stock after the offering by such securityholder.

     We prepared this table based on the information supplied to us by the selling securityholders named in the table prior to the date hereof. The selling securityholders listed in the above table may have sold or transferred, in transactions exempt from the registration requirements of the Securities Act, some or all of their notes since the date on which the information is presented in the above table. Information about the selling securityholders may change over time. Any changed information will be set forth in prospectus supplements to the accompanying prospectus.

     Because the selling securityholders may offer all or some of their notes or the underlying common stock from time to time, we cannot estimate the amount of the notes or the underlying common stock that will be held by the selling securityholders upon the termination of any particular offering. See “Plan of Distribution” in the accompanying prospectus.

     None of the named selling securityholders nor any of their affiliates, officers, directors or principal equity holders has held any position or office or has had any material relationship with us within the past three years.

     Investing in the notes involves risks. See “Risk Factors” beginning on page 7 of the accompanying prospectus.

            

     Neither the Securities and Exchange Commission nor any other federal or state securities commission or regulatory authority has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is July 21, 2004.
