This prospectus supplement should be read in conjunction with the prospectus. Capitalized terms used and not defined in this prospectus supplement have the meaning given to them in the prospectus.

Investing in the notes or our common stock involves risks. See "Risk Factors" beginning on page 6 of the prospectus.

The Securities and Exchange Commission and state securities regulators have not approved or disapproved these securities or determined if this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is March 4, 2005.

        The section of the prospectus entitled "Selling Securityholders" on pages 48-53 of the prospectus is amended and restated in its entirety to read as follows:

SELLING SECURITYHOLDERS

        We originally sold the notes on December 12, 2003 to Morgan Stanley & Co. Incorporated, Credit Suisse First Boston LLC and U.S. Bancorp Piper Jaffray Inc., as initial purchasers. The initial purchasers of the notes have advised us that the notes were resold in transactions exempt from the registration requirements of the Securities Act to "qualified institutional buyers," as defined in Rule 144A of the Securities Act. These subsequent purchasers, or their transferees, pledgees, donees or successors, may from time to time offer and sell any or all of the notes and/or shares of the common stock issuable upon conversion of the notes pursuant to this prospectus.

        Pursuant to the registration rights agreement, we are required to file a registration statement with regard to the notes and the shares of our common stock issuable upon conversion of the notes and to keep the registration statement effective until the earlier of:

•

such date when no registrable securities remain outstanding; and



•

such date that is two years after the date the Commission declares this registration statement effective.

        The selling securityholders may choose to sell notes and/or the shares of common stock issuable upon conversion of the notes from time to time. The transfer of the securities is further discussed under the heading "Plan of Distribution."

        The following table sets forth:

(1)

the name of each selling securityholder who has provided us with notice as of the date of this prospectus pursuant to the registration rights agreement of their intent to sell or otherwise dispose of notes and/or shares of common stock issuable upon conversion of the notes pursuant to the registration statement;



(2)

the principal amount of notes and the number of shares of our common stock issuable upon conversion of the notes which they may sell from time to time pursuant to the registration statement; and



(3)

the amount of outstanding notes and our common stock beneficially owned by the selling securityholder prior to the offering, assuming no conversion of the notes.

        To our knowledge, no selling securityholder nor any of its affiliates has held any position or office with, been employed by or otherwise has had any material relationship with us or our affiliates, during the three years prior to the date of this prospectus.

        A selling securityholder may offer all or some portion of the notes and shares of the common stock issuable upon conversion of the notes. Accordingly, no estimate can be given as to the amount or percentage of notes or our common stock that will be held by the selling securityholders upon termination of sales pursuant to this prospectus. In addition, the selling securityholders identified below may have sold, transferred or disposed of all or a portion of their notes since the date on which they provided the information regarding their holdings in transactions exempt from the registration requirements of the Securities Act.

        The information contained under the column heading "Shares of Common Stock That May be Sold" assumes conversion of:

•

the full amount of Series A notes held by the holders at the initial rate of $31.8928 in principal amount of the Series A notes per share of common stock; and



•

the full amount of Series B notes held by the holders at the initial rate of $29.8352 in principal amount of the Series B notes per share of common stock.
