                                          FORM 10-K/A
                                        Amendment No. 1



The Issuing Entity is filing this Form 10-K/A to replace Exhibits 31,
33(a),33(b), 34(a), and 34(b) to the original Form 10-K filed on April 2, 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 these revised
assessments of compliance under Exhibits 33(a) and 33(b), the related
attestations under Exhibits 34(a) and 34(b), 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 April 2,
2007.

            and December 31, 2005, and for each of the years in the three-year

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


            See Exhibit (33) and (34)

  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 First American Real Estate Solutions of Texas, L.P.
  (as Sub-Contractor for Fifth Third Mortgage Company ) has disclosed the
  following material instance of noncompliance with the servicing criteria set
  forth in Item 1122(d)(2)(vii)(B) of Regulation AB applicable to the Company
  during year ended December 31, 2006. Account reconciliations for all
  asset-backed securities related bank accounts were not prepared within 30
  calendar days after the bank statement cutoff date, or such other number of
  days specified in the transaction agreements as required by Item
  1122(d)(2)(vii)(B) of Regulation AB.


1. GreenPoint has identified the following noncompliance with servicing criteria
   1122(d)(1)(i), 1122(d)(2)(iv), and 1122(d)(3)(ii) applicable to the Platform
   during the year ended December 31, 2006 as follows:

   1122(d)(1)(i) - GreenPoint did not institute policies and procedures to
   monitor performance or other triggers and events of default in accordance
   with the transaction agreements.

   1122(d)(2)(iv) - GreenPoint did not establish separate P&I and T&I accounts
   for certain securitizations which allowed funds to be commingled in various
   custodial accounts.

   1122(d)(3)(ii) - In certain situations where GreenPoint has received mortgage
   insurance proceeds prior to the liquidation of the related properties, the
   mortgage insurance proceeds were not remitted at the time of the next
   regularly scheduled remittance date as required by the transaction
   agreements, but instead remained in the related custodial account and were
   remitted at the time the REO liquidation proceeds were remitted to the Master
   Servicer.


2. GreenPoint has implemented the following remediation procedures:

   1122(d)(1)(i) - GreenPoint has active monitoring of the entire portfolio and
   at investor levels but not at the securitization transaction level.
   GreenPoint will establish policies and procedures to monitor performance or
   other triggers and events of default in accordance with the transaction
   agreements.

   1122(d)(2)(iv) - GreenPoint has separated the commingled funds and
   established proper custodial and escrow accounts and improved the oversight
   of establishing such accounts as required by the related agreements.

   1122(d)(3)(ii) - GreenPoint is modifying applicable agreements to clarify
   that such mortgage insurance proceeds may be remitted at the time of the
   remittance of the REO liquidation proceeds or modifying its remittance
   practice to remit the mortgage insurance proceeds during the next regularly
   schedule remittance where required.


  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
  Servicers', Fifth Third Mortgage Company, GMAC Mortgage LLC f/k/a GMAC
  Mortgage Corporation, and GreenPoint Mortgage Funding Inc., Assessments of
  Compliance and related Attestation Reports did not address each of the
  servicing criteria that the Servicers were required to address under the terms
  of the related Servicing Agreements. The Servicers have 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 Servicers assert that those items are not applicable to the
  Servicers.


  Item 1123 of Regulation AB, Servicer Compliance Statement.
