SELLING SECURITYHOLDERS

The information in the table appearing under the heading "Selling Securityholders" beginning on page 76 of the prospectus is amended by adding the information below with respect to persons not previously listed in the prospectus, and by superseding the information with respect to persons listed in the prospectus that are listed below.

The following table sets forth certain information as of August 1, 2005, except where otherwise noted, concerning the principal amount of debentures 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 debentures shown in the table below assumes conversion of the full amount of debentures held by each holder at an initial conversion price of $29.10 per share. This conversion price is subject to adjustments in certain circumstances. Because the selling securityholders may offer all or some portion of the debentures or the common stock issuable upon conversion of the debentures, we have assumed for purposes of the table below that the named selling securityholders will sell all of the debentures or convert all of the debentures and sell all of the common stock issuable upon conversion of the debentures 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 debentures since the date on which they provided the information regarding their debentures 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. Because the selling securityholders may offer all or some of their debentures or the underlying common stock from time to time, we cannot estimate the amount of debentures or underlying common stock that will be held by the selling securityholders upon the termination of any particular offering. See "Plan of Distribution" for further information.
