Selling Securityholders

                The following information supplements and updates the table of selling securityholders contained on pages 67 through 68 of the prospectus, as such table has been previously supplemented and updated by previous prospectus supplements.  Where the name of a selling securityholder identified in the table below appears in the table in the prospectus or the earlier prospectus supplements, the information set forth in the table below regarding that selling securityholder supersedes and replaces the information regarding such selling securityholder in the prospectus or the earlier prospectus supplements.

                The information below, which has been prepared based on information furnished to us by or on behalf of the selling securityholders named therein, sets forth the name of each selling securityholder, the principal amount of notes that each selling securityholder owns and may offer pursuant to the prospectus, as amended or supplemented, and the number of common shares into which those notes are convertible.  Unless set forth below, to our knowledge, none of the selling securityholders has, or within the past three years has had, any material relationship with us or any of our predecessors or affiliates or beneficially owns in excess of 1% of our outstanding common shares.

                We have prepared the table below based on information received from the selling securityholders on or prior to June 23, 2008.  However, any or all of the notes or common shares listed below may be offered for sale pursuant to the prospectus by the selling securityholders from time to time.  Accordingly, no estimate can be given as to the amount of notes or number of common shares that will be held by the selling securityholders upon consummation of any sales.  In addition, the selling securityholders listed in the table below may have acquired, sold or transferred, in transactions exempt from the registration requirements of the Securities Act of 1933, as amended, some or all of their notes since the date as of which the information in the table is presented.

                Information about the selling securityholders may change over time, and we may not be made aware of changes in the ownership of our notes.  Any changed information that is provided to us by selling securityholders will be set forth in additional prospectus supplements to the prospectus.

(2)          Represents maximum number of common shares issuable upon conversion of notes by a named selling securityholder at an initial conversion rate of 19.8018 common shares per $1,000 principal amount of notes (subject to adjustment under certain circumstances—see “Description of Notes—Conversion Rights” in the prospectus).

(3)          The selling securityholder has disclosed that it is a registered broker-dealer.  Therefore, it may be deemed to be, under interpretations of the Securities and Exchange Commission, an “underwriter” within the meaning of the Securities Act of 1933, as amended.  Any profits realized by this selling securityholder may be deemed to be underwriting commissions.  This selling securityholder has represented that it acquired its securities in the ordinary course of business, and, at the time of the acquisition of the securities, had no agreements or understandings to distribute the securities.   The securities are under the total control of KBC Financial Products Cayman Islands Ltd.  KBC Financial Products Cayman Islands Ltd. is a direct wholly-owned subsidiary of KBC Financial Holdings, Inc., which in turn is a direct wholly-owned subsidiary of KBC Bank N.V., which in turn is a direct wholly-owned subsidiary of KBC Group N.V., a publicly traded entity.

(6)          A maximum of 5,000,000 common shares have been registered for resale upon conversion of the notes.  Amounts in the table above may add up to more than 5,000,000 but in no event will we issue more than 5,000,000 common shares for resale under the prospectus, as supplemented.  We do not anticipate issuing more than an aggregate of 5,000,000 shares in connection with conversions of the notes due to our ability to settle a portion of the conversions in cash.  See “Description of Notes-Conversion Settlement” in the prospectus.
