The section entitled Selling Securityholders in the prospectus is superceded in its entirety with the following:
SELLING SECURITYHOLDERS
We originally issued the notes in a private placement in May 2007 to Bear, Stearns & Co. Inc. and Banc of America Securities LLC, as representatives of the initial purchasers (the Representatives). The initial purchasers resold the notes to purchasers they reasonably believed to be qualified institutional buyers in transactions exempt from registration pursuant to Rule 144A under the Securities Act. The selling securityholders listed below and, to the extent permitted, their transferees, pledgees, donees, assignees, successors, partnership distributees and others who later hold any of the selling securityholders interests, to which we collectively refer as the selling securityholders, may from time to time offer and sell any and all of the notes and the shares of common stock issuable upon conversion of the notes pursuant to this prospectus or any applicable prospectus supplement. The Representatives have in the past and may in the future provide financial advisory and other services to us and our affiliates.
The following table and related footnotes show information received by us on or prior to March 3, 2008, with respect to the selling securityholders and the principal amounts of notes and our common stock issuable upon conversion of the notes beneficially owned that may be offered under this prospectus or any applicable prospectus supplement. We prepared this table based on the information supplied to us by or on behalf of the selling securityholders named in the table, and we have not sought to verify such information. Information concerning the selling securityholders may change from time to time and any changed information will be set forth in amendments or supplements to this prospectus or any applicable prospectus supplement if and when necessary.
The selling securityholders may offer all, some or none of the notes or common stock into which the notes are convertible. Thus, we cannot estimate the amount of the notes or the common stock that will be held by the selling securityholders upon consummation of any sales. The column showing ownership after completion of the offering assumes that the selling securityholders will sell all of the securities offered by this prospectus or any applicable prospectus supplement. Unless set forth below, none of the selling securityholders has held any position or office or had any material relationship with us or our affiliates within the past three years. All of the notes were restricted securities under the Securities Act prior to this registration. In addition, the selling securityholders identified below may have sold, transferred or otherwise disposed of all or a portion of their notes since the date on which they provided the information about their notes in transactions exempt from the registration requirements of the Securities Act.
