  Item 1122 of Regulation AB, Compliance with Applicable Servicing Criteria.

            (a) See Exhibit 33 and Exhibit 34.

            (b) Material instances of noncompliance:

                On or about March 11, 2008, Assurant, Inc. provided the
                Registrant with a management's assessment of compliance with
                servicing criteria set forth in Item 1122(d) of Regulation AB
                and a registered public accounting firm assessment as set forth
                in Item 1122(b) of Regulation AB (the "Assurant Reports"). The
                Assurant Reports are attached as Exhibit 33(a) and
                Exhibit 34(a), respectively, to this report.

                Assurant, Inc. previously excluded the applicable servicing
                criteria set forth in Item 1122 (d)(4)(xii) from the scope of
                its assessment of compliance. Assurant, Inc. has now assessed
                its compliance with the Applicable Servicing Criteria for the
                Reporting Period and has identified a material instance of
                noncompliance with that servicing criterion. Specifically,
                Assurant, Inc. did not have, during the Reporting Period,
                sufficient policies and procedures to capture the information
                with respect to the Platform Transactions necessary to determine
                compliance with Item 1122(d)(4)(xii). Accordingly, Assurant,
                Inc. has restated its previous assessment for the Reporting
                Period, which excluded evaluation of the criterion, to include
                the criterion and reflect the material noncompliance as a result
                of its assessment.


                On or about March 11, 2008, Avelo provided the Registrant with
                a revised management's assessment of compliance with servicing
                criteria set forth in Item 1122(d) of Regulation AB and a
                registered public accounting firm assessment as set forth in
                Item 1122(b) of Regulation AB (the "Avelo Reports"). The Avelo
                Reports are attached as Exhibit 33(b) and Exhibit 34(b)
                respectively, to this report.


                Avelo Mortgage, L.L.C. has complied, in all material respects,
                with the applicable servicing criteria as of and for the
                Reporting Period except as follows:

                Avelo Mortgage, L.L.C. assessed its compliance with the
                Applicable Servicing Criteria for the Reporting Period and has
                identified a material instance of non-compliance with servicing
                criterion set forth in Item 1122(d)(2)(vii) of Regulation AB
                with respect to the Platform. Specifically, Avelo Mortgage,
                L.L.C. did not prepare reconciliations for all asset-backed
                securities related bank accounts within 30 calendar days after
                the bank statement cut-off date, or as such other number of days
                as specified in the transaction agreements and reconciling items
                were not resolved within 90 days of their original
                identification or such other number of days as specified in the
                transaction agreements.



                Material instances of noncompliance by Wells Fargo Bank,
                National Association:

                1122(d)(3)(i) Delinquency Reporting: During the reporting
                period, certain monthly investor or remittance reports included
                errors in the calculation and/or the reporting of delinquencies
                for the pool assets, which errors may or may not have been
                material. All such errors were the result of data processing
                errors and/or the mistaken interpretation of data provided by
                other parties participating in the servicing function. All
                necessary adjustments to data processing systems and/or
                interpretive clarifications have been made to correct those
                errors and to remedy related procedures.
