                   investors did not provide information with respect to certain
                   liquidation proceeds calculated in accordance with the terms
                   specified in the transaction agreements;

                   (iii) with respect to Item 1122(d)(3)(ii), certain
                   liquidation proceeds and prepayment fees due to investors
                   were not allocated and remitted in accordance with

              The Report on Assessment of Compliance With Servicing Criteria for

              American Security Insurance Company, Standard Guaranty Insurance
              Company and TrackSure Insurance Agency, Inc. (affiliates of
              Assurant Inc.), included as Exhibits 33.4 and 34.4, respectively,
              to this Form 10-K identified a material instance of noncompliance
              with the servicing criterion set forth in Item 1122(d)(4)(xii) of
              Regulation AB. Specifically, American Security Insurance Company,
              Standard Guaranty Insurance Company and TrackSure Insurance
              Agency, Inc. did not have sufficient policies and procedures to
              capture the information necessary to determine compliance with
              Item 1122(d)(4)(xii) of Regulation AB, which requires that any
              late payment penalties in connection with any payment to be made
              on behalf of an obligor are paid from the servicer's funds are not
              charged to the obligor, unless the late payment was due to the
              obligor's error or omission. The Company has received a letter
              from American Security Insurance Company, Standard Guaranty
              Insurance Company and TrackSure Insurance Agency, Inc.
              (affiliates of Assurant Inc.) stating that as of January 1, 2008
              practices and procedures have been implemented to capture the
              information necessary to assess compliance with Item
              1122(d)(4)(xii) of Regulation AB. The Company, however, has taken
              no steps to independently verify, and has not been able to
              independently verify, the contents of that letter.
