The Seller Parties, the Purchasers and the Agents are parties to that certain Second Amended and Restated Receivables Purchase Agreement dated as of February 21, 2008, as heretofore amended (the “RPA”; capitalized terms used and not otherwise defined herein are used with the meanings attributed thereto in the RPA).

Certain events of default have occurred under the ABL Credit Agreement, as a result of which, Amortization Events exist under Sections 9.1(d), (f) and (k) of the RPA and a Termination Event exists under Section 5.1(d) of the U.S. Receivables Sale Agreement. In addition, an Amortization Event has occurred under Section 9.1(u) of the RPA.

The lenders party to the ABL Credit Agreement are entering into a Amendment No. 16 to Amended and Restated Credit Agreement and Waiver dated as of the date hereof pursuant to which they will waive the events of default thereunder and make certain amendments to the terms thereof (the “ABL Waiver and Amendment”). The Seller Parties have requested that the Agents and the Purchasers (i) consent to the ABL Waiver and Amendment, (ii) waive such Amortization Events and Termination Event and (iii) amend the RPA as set forth herein. The Agents and the Purchasers are willing to agree to such consent, waiver and amendments only on the terms and subject to the conditions hereinafter set forth.
