Note Insurer, as the Controlling Party under the Transaction Documents, has

amended as provided for herein to document fully the effect of such waivers; and

provided for herein are of a type permitted by Section 8.02(b) of the Servicing
Agreement without requiring the consent of the noteholders under the Indenture.

                  Agreement, within 15 Business Days thereafter and, to the
                  extent there has been a temporary waiver, permanently waived
                  in writing, in accordance with the terms of the Credit
                  Agreement, within 30 days; provided that any such exception
                  resulting from a temporary waiver shall extend only to the
                  earlier of the date on which such temporary waiver expires or
                  12:00 midnight on the 30th day after the date of the original
