This Amendment No. 1 to the Annual Report on Form 10-K filed with the Securities
and Exchange Commission on April 2, 2007 (Accession No. 0001056404-07-001592)
by Structured Asset Mortgage Investments II Trust 2006-AR8 (the "Initial 10-K"),
for the fiscal year ended December 31, 2006, is being filed for the sole purpose
of restating the assessment of American Security Insurance Company, Standard
Guaranty Insurance Company and TrackSure Insurance Agency, Inc. (the "Asserting
Party") for the reporting period of January 1, 2006 through December 31, 2006.
The restated assessment, provided to the registrant in February 2008, identifies
a material instance of noncompliance with the servicing criteria set forth in
Item 1122(d)(4)(xii) under Regulation AB. Specifically, the Asserting Party did
not have, during the applicable 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). In response to a
Securities and Exchange Commission comment, as of January 1, 2008, the Asserting
Party has implemented practices and procedures to capture the information
necessary to assess compliance with Item 1122(d)(4)(xii).

  Item 1119 of Regulation AB, Affiliations and Certain Relationships and
             Related Transactions.


            On February 9, 2007, Bear Stearns Residential Mortgage Corporation,
            a wholly owned subsidiary of The Bear Stearns Companies Inc. and an
            affiliate of the Registrant, acquired certain assets used in the
            subprime wholesale mortgage banking division of Performance Credit
            Corporation (formerly known as Encore Credit Corp.) ("PCC"), a
            California corporation that, until February 9, 2007, originated and
            purchased one-to four-family residential mortgage loans offered to
            borrowers with a particular emphasis on "nonconforming" borrowers
            who generally do not satisfy the credit, collateral, documentation
            or other standards required by conventional mortgage lenders and
            loan buyers.


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


            The servicing criteria have been completed within the manner stated
            in the governing documents and are attached hereto under Item 15.

            The restated assessment of American Security Insurance Company,
            Standard Guaranty Insurance Company and TrackSure Insurance Agency,
            Inc. (the "Asserting Party") for the reporting period of January 1,
            2006 through December 31, 2006, provided to the registrant in
            February 2008, identifies a material instance of noncompliance with
            the servicing criteria set forth in Item 1122(d)(4)(xii) under
            Regulation AB. Specifically, the Asserting Party did not have,
            during the applicable 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). In response to a Securities and Exchange Commission comment,
            as of January 1, 2008, the Asserting Party has implemented practices
            and procedures to capture the information necessary to assess
            compliance with Item 1122(d)(4)(xii).

            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.

            Although each servicing criterion required by Item 1122(d) of
            Regulation AB is addressed in one or more of the Assessments of
            Compliance with Servicing Criteria and related Attestation Reports
            included with this report, the Servicer's, Countrywide Home Loans
            Servicing LP, Assessment of Compliance and related Attestation
            Report did not address each of the servicing criteria that the
            Servicer was required to address under the terms of the related
            Servicing Agreement. The Servicer has not identified such failure to
            provide an Assessment and Attestation for these items as a material
            failure to fulfill its obligations under the related servicing
            agreement in the Servicer's Compliance Statement provided under Item
            1123 of Regulation AB, because the Servicer asserts that those items
            are not applicable to the Servicer.



  Item 1123 of Regulation AB, Servicer Compliance Statement.


            The servicer compliance statements have been completed within the
            manner stated in the governing documents and are attached hereto
            under Item 15.
