     B. We have become aware that “Defaults” and “Events of Default” may have occurred under the Parent Credit Agreement as of October 1, 2008 (the “Credit Agreement Defaults”) as a result of non-compliance by the borrower thereunder with certain covenants contained in Section 7.1(a) and Section 7.1(b) of the Parent Credit Agreement. To the extent of such Defaults and Events of Default, a Termination Event has occurred under clause (h)(ii) of the definition of Termination Event in the Sale Agreement (collectively, together with the Potential Termination Events and Termination Events resulting directly therefrom, including, without limitation, the circumstances described in the next sentence,. the “Existing Termination Events”). In addition, to the extent of the occurrence of the Existing Termination Events, the Seller should not have and should not have been since September 30, 2008 permitted to accept any additional Purchases under Section 7.2 of the Sale Agreement and the Collection Agent is required to set aside and hold in trust all Collections for application pursuant to Section 2.3(b) of the Sale Agreement. Failure to comply with such obligations would also result in Potential Termination Events or Termination Events under the Sale Agreement.

     C. The Seller has requested that the Agent and the Purchasers waive the Existing Termination Events under the terms and conditions set forth herein.

     D. The Agent and Purchasers constituting the Instructing Group (collectively, the “Waiving Parties”) are willing to waive the Existing Termination Events subject to the terms hereof.

     E. In order to accommodate the Seller’s request, during and only during the period (the “Waiver Period”) beginning on the Effective Date (as defined below) of this Amendment and Waiver, but with effect as of the date hereof, and ending on November 25, 2008 (the “Scheduled Waiver Expiration Date”), the Waiving Parties are willing to waive the Existing Termination Events on the terms, conditions, and provisions contained in this Amendment and Waiver.

     F. The parties hereto also desire to amend the Sale Agreement pursuant to Section 9.6 of the Sale Agreement under the terms and conditions provided herein;

     NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby agree that the Sale Agreement shall be and is hereby amended as follows:

The defined terms in the Recitals set forth above are hereby incorporated into this Amendment and Waiver by reference. All other capitalized terms used herein without definition shall have the same meanings herein as such terms have in the Sale Agreement.

     2. Acknowledgment of Default(s). The Existing Termination Events constituted a Termination Event under the Sale Agreement. Each of the Seller and Collection Agent represents to the Agent and Purchasers that there are no Potential Termination Events other than the Existing Termination Events.
