          NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein, the Borrower, the Lenders, the Administrative Agent and the Other Agents hereby agree as follows:

          1. Defined Terms. Unless otherwise defined herein, capitalized terms which are defined in the Credit Agreement, as amended hereby, are used herein as therein defined.

          2. Waiver, etc. The Required Lenders hereby waive (a) any Default or Event of Default (a) under Section 4.1 of the Credit Agreement, Section 6.1 of the Credit Agreement or any other provision of the Credit Agreement or any other Loan Document requiring an item or calculation to be determined in accordance with GAAP or resulting from the bring-down of representations and warranties by the Borrower or satisfaction of conditions in connection with any prior extension of credit under the Credit Agreement, in each case resulting from the Restatement; provided that the foregoing shall not be deemed to waive any Default or Event of Default with respect to a Financial Covenant, and (b) through September 30, 2007, delivery of the financial statements and certificates described in Sections 6.1 and 6.2 of the Credit

          3. Representations and Warranties. The Borrower hereby confirms that the representations and warranties set forth in Section 4 of the Credit Agreement (excluding Section 4.1 to the extent described herein), as amended by this Waiver, are true and correct in all material respects as if made as of the Waiver Effective Date (except such representations and warranties as are made as of a particular date, which such representations and warranties shall be true and correct in all material respects as if made as of such date).

          5. Continuing Effect of the Credit Agreement. This Waiver shall not constitute an amendment or waiver of any provision of the Credit Agreement not expressly referred to herein and shall not be construed as a waiver or consent to any further or future action on the part of the Borrower that would require a waiver or consent of the Lenders, the Administrative Agent or the Other Agents. Except as expressly amended hereby, the provisions of the Credit Agreement are and shall remain in full force and effect.

          6. Counterparts. This Waiver may be executed by the parties hereto in any number of separate counterparts (including telecopied counterparts), each of which shall be deemed to be an original, and all of which taken together shall be deemed to constitute one and the same instrument.

          IN WITNESS WHEREOF, the parties hereto have caused this Waiver to be duly executed and delivered by their respective proper and duly authorized officers as of the day and year first above written.
