The section entitled “Selling Security Holders” in the Prospectus is superseded in its entirety with the following:

SELLING SECURITY HOLDERS

On August 9, 2007, we issued all of the notes to Lehman Brothers Inc. The initial purchaser then resold the notes to persons reasonably believed by the initial purchaser to be qualified institutional buyers in reliance on Rule 144A of the Securities Act. Based on representations made to us by the selling security holders, we believe that the selling security holders purchased the notes in the ordinary course of business and that at the time of the purchase of the notes, such selling security holders had no agreements or understandings, directly or indirectly with any person to distribute such securities. All of the notes were issued as “restricted securities” under the Securities Act. Selling security holders may from time to time offer and sell pursuant to this prospectus any or all of the notes and shares of common stock issuable upon conversion of the notes.

The following table sets forth information, as of December 20, 2007, with respect to the selling security holders and the principal amounts of notes beneficially owned by each selling security holder that may be offered pursuant to this prospectus. The information is based on information provided by or on behalf of the selling security holders. The selling security holders may offer all, some or none of the notes or the common stock issuable upon conversion of the notes. The selling security holders 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 regarding their notes in transactions exempt from the registration requirements of the Securities Act. The number of shares of common stock owned prior to the offering includes shares of common stock issuable upon conversion of the notes. The percentage of common stock outstanding beneficially owned by each selling security holder is based on 605,486,837 shares of common stock outstanding on December 18, 2007. The number of shares of common stock issuable upon conversion of the notes offered hereby is based on a conversion price of $20.13 per share and a cash payment in lieu of any fractional share.
