                                        FORM 10-K/A
                                      Amendment No. 1

  The Issuing Entity is filing this Form 10-K/A to replace Exhibits 31, 33(a)
  and 34(a) to the original Form 10-K filed on March 30, 2007. American
  Security Insurance Company, Standard Guaranty Insurance Company and TrackSure
  Insurance Agency, Inc. (formerly, "Safeco Financial Institution Solutions,
  Inc.") ("Assurant Inc.") recently provided the Issuing Entity with a revised
  report on assessment of compliance with servicing criteria for asset-backed
  securities and a related attestation. In the original assessment previously
  provided to the Issuing Entity, Assurant Inc. excluded Item 1122(d)(4)(xii)
  from the scope of its assessment. Assurant Inc. recently provided the Issuing
  Entity with a revised assessment of compliance that assesses Assurant Inc.'s
  compliance with Item 1122(d)(4)(xii) and identifies material instance of non
  compliance with this criterion. This material instance of non compliance is
  noted in this Form 10-K/A under "Additional Disclosure Items Pursuant to
  General Instruction J." The Issuing Entity has included this revised
  assessment of compliance under Exhibit 33(a), the related attestation under
  Exhibit 34(a) and a revised Rule 13a-14(d)/15d-14(d) Certification under
  Exhibit 31. This Form 10-K/A does not otherwise amend the original Form 10-K
  filed with the Commission on March 30, 2007.

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


    Reports on assessment of compliance with the servicing criteria
    for asset-backed securities are attached hereto under Item 15.


            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 of
            January 1, 2006 through December 31, 2006 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.


            The 1122 statements for GreenPoint Mortgage Funding, Inc. has
            disclosed the following material noncompliance with servicing
            criteria 1122(d)(1)(i), 1122(d)(2)(iv), and 1122(d)(3)(ii)
            applicable to the Company's platform covered by this report
            during the year ended December 31, 2006. 1122(d)(1)(i) - There
            were no policies and procedures instituted to monitor the
            performance or other triggers and events of defaults in
            accordance with the transaction agreements; 1122(d)(2)(iv) - The
            related accounts for each transaction were not separately
            maintained as set forth in the transaction agreements; and,
            1122(d)(3)(ii) - Amounts due to investors were not remitted in
            accordance with the timeframes set forth in the transaction
            agreements.

             The 1122 statements for Wells Fargo Bank, National Association
            (Corporate Trust Services) has disclosed material noncompliance with
            criterion 1122(d)(3)(i), as applicable to the Company during the
            twelve months ended December 31. 2006.  Certain monthly investor or
            remittance reports included errors in the calculation and/or the
            reporting of delinquencies for the pool assets.


  Item 1123 of Regulation AB, Servicer Compliance Statement.

       Servicer compliance statements are attached hereto under Item 15.
