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

            Information required by Item 1119 was provided previously in a
            prospectus timely filed pursuant to Rule 424 promulgated under the
            Securities Act of 1933, under the same Central Index Key (CIK) code
            as this annual report on Form 10-K. No material changes to such
            information have occurred since the initial Rule 424 filing.

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

             See Item 15, exhibits (33) and (34) and as otherwise disclosed
             below.

               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  assessment  of  compliance  of 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.  Such assessment further states that 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.  The assessment  also indicates that all
               necessary   adjustments   to  data   processing   systems  and/or
               interpretive  clarifications  have  been  made to  correct  those
               errors and to remedy related procedures.

              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, Assessment of Compliance and
              related Attestation Report of Countrywide Home Loans Servicing LP,
              as Servicer, 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.   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.


  Item 1123 of Regulation AB, Servicer Compliance Statement.
