     The information in this prospectus supplement concerning the selling securityholders supplements the statements set forth under the caption “Selling Securityholders” in the prospectus. Capitalized items used and not defined herein shall have the meanings given to them in the prospectus. The information set forth under the caption “Selling Securityholders” in the prospectus is supplemented as follows:

SELLING SECURITYHOLDERS

     We originally issued the convertible notes covered by this prospectus on December 12, 2003 and January 7, 2004 to Credit Suisse First Boston LLC, whom we refer to as the initial purchaser of the convertible notes. The initial purchaser of the convertible notes advised us that the convertible 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 convertible notes and/or shares of the common stock issuable upon conversion of the convertible notes pursuant to this prospectus.

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

          (1) the sale of all the securities registered pursuant to the registration rights agreement, and

          (2) the expiration of the holding period applicable to these securities under Rule 144(k) under the Securities Act or any successor provision.

     The selling securityholders may choose to sell convertible notes and/or the shares of common stock issuable upon conversion of the convertible notes from time to time. See “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 that they may intend to sell or otherwise dispose of convertible notes and/or shares of common stock issuable upon conversion of the convertible notes pursuant to the registration statement,

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

          (3) the amount of outstanding convertible notes and share of our common stock beneficially owned by the selling securityholder after completion of the

offering (excluding any shares owned or acquired other than upon conversion of the convertible 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 convertible notes and shares of the common stock issuable upon conversion of the convertible notes. Accordingly, no estimate can be given as to the amount or percentage of convertible 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 convertible 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” represents shares issuable upon conversion of the principal amount of convertible notes listed and assumes conversion of the full amount of the convertible notes at the initial rate of $15.45 per $1,000 in principal amount of the convertible notes. The information in the last row of the table below reflects securities held by the remaining selling securityholders. We are unable to provide the names of these securityholders because certain of these convertible notes are currently evidenced by a global convertible note which has been deposited with DTC and registered in the name of Cede & Co. as DTC’s nominee.
