     WHEREAS, the Trust desires to have the Bond Administrator and the Administrator, respectively, perform certain of the duties of the Trust referred to in the preceding clause, and to provide such additional services consistent with the terms of this Agreement, the Related Agreements and the Trust Agreement as the Trust may from time to time request; and

     WHEREAS, the Bond Administrator and the Administrator have the capacity to provide the respective services required hereby and are willing to perform such services for the Trust and the Owner Trustee on the terms set forth herein.

     NOW, THEREFORE, in consideration of the mutual covenants contained herein, and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows:

     Section 1. Duties of the Bond Administrator.

          (i) The Bond Administrator accepts its appointment as Bond Administrator and agrees to perform such duties as are specifically set forth hereunder. The Bond Administrator shall not have any duties or responsibilities except those expressly set forth in this Agreement or be a trustee for or have any fiduciary obligation to any party hereto.
