EX-33 (a)
Certification Regarding Compliance with Applicable Servicing Criteria

1.   Ameriquest Mortgage Company and AMC Mortgage Services, Inc. (together the
     "Company"), wholly-owned subsidiaries of ACC Capital Holding Corporation,
     are responsible for assessing compliance with the servicing criteria
     applicable to the Company under paragraph (d) of Item 1122 of Regulation
     AB, as of and for the 12-month period ending December 31, 2006 (the
     "Reporting Period"), as set forth in Appendix B hereto. The transactions on
     which the Company acted as a master servicer, a servicer and/or a
     subservicer which are subject to the requirements set forth in Regulation
     AB and covered by this report are set forth on Appendix A hereto (the
     "Platform");

2.   The Company has engaged certain vendors (the "Vendors") to perform
     specific, limited or scripted activities, and the Company has elected to
     take responsibility for assessing compliance with the servicing criteria or
     portion of the servicing criteria applicable to such Vendors' activities as
     set forth in Appendix B hereto, as permitted by Interpretation 17.06 of
     the Securities and Exchange Commission Division of Corporate Finance Manual
     of Publicly Available Telephone Interpretations ("Interpretation 17.06"),
     except for certain Vendors that have provided their own reports on
     assessment of compliance with the applicable servicing criteria. The
     Company determined the Vendors for which the Company has elected to take
     responsibility for assessing compliance with the applicable servicing
     criteria are not "servicers" as defined in Item 1101(j) of Regulation AB
     and asserted that it has policies and procedures in place to provide
     reasonable assurance that these Vendors' activities comply, in all material
     respects, with the servicing criteria applicable to each such Vendor;

3.   Except as set forth in paragraph 4 below, the Company used the criteria set
     forth in paragraph (d) of Item 1122 of Regulation AB to assess the
     compliance with the applicable servicing criteria. Although the Company is
     responsible for assessing compliance with the servicing criterion
     1122(d)(4)(vi), the Company has determined there were no servicing
     criterion to be complied with;

4.   The criteria listed in the column titled "Inapplicable Servicing Criteria"
     on Appendix B hereto are inapplicable to the Company based on the
     activities it performs, directly or through its Vendors for which the
     Company has elected to take responsibility for assessing compliance with
     the applicable servicing criteria, with respect to the Platform when taken
     as a whole, as of December 31, 2006 and for the Reporting Period;

5.   The Company has complied, in all material respects, with the applicable
     servicing criteria as of December 31, 2006 and for the Reporting Period
     with respect to the Platform taken as a whole, except as described on
     Appendix C hereto;

6.   The Company has not identified and is not aware of any material instance of
     noncompliance as of December 31, 2006 and for the Reporting Period with
     respect to the Platform taken as a whole by the Vendors for which the
     Company has elected to take responsibility for assessing compliance with
     the applicable servicing criteria;

7.   The Company has not identified any material deficiency in its policies and
     procedures to monitor the compliance by the Vendors for which the Company
     has elected to take


(page)


     responsibility for assessing compliance, with the applicable servicing
     criteria as of December 31, 2006 and for the Reporting Period with respect
     to the Platform, taken as a whole;

8.   Ernst & Young, LLP, an independent registered public accounting firm, has
     issued an attestation report on the Company's assessment of compliance with
     the applicable servicing criteria for the Reporting Period.

Other Matters to be Reported:

     As further described on Appendix C hereto, due to a programming error in
     their servicing system, the Company did not analyze on a timely basis as
     required in accordance with the servicing criterion 1122(d)(4)(x)(A)
     certain escrow accounts on the Regulation AB Item 1122 Servicing Platform
     which were due for annual escrow analysis in 2007.

     The Company engaged American Security Insurance Company, Standard Guaranty
     Insurance Company and Safeco Financial Institution Solutions, Inc.
     (collectively "Assurant") to perform portions of the servicing functions,
     including those pursuant to the servicing criterion 1122(d)(4)(xii).
     Assurant provided its own report on assessment of compliance; however, it
     did not assert to the servicing criterion 1122(d)(4)(xii) as further
     described on Appendix C hereto.

(2)  These criteria are inapplicable to the Platform as of December 31, 2006 and
     for the Reporting Period since the Company, directly or through Vendors for
     which the Company has elected to take responsibility for assessing
     compliance with the applicable servicing criteria, was not required to
     perform any related activities.

(3)  The Company has obtained an assertion of management and an accompanying
     1122 attestation report from a Vendor regarding any unissued checks solely
     in the possession and control of such Vendor.

(4)  The Company has elected to take responsibility for assessing compliance
     with a portion of such servicing activity as permitted by Interpretation
     17.06 with respect to collateral and security on mortgage loan files while
     held by Vendors who are pursuing loss mitigation or recovery actions.

(5)  The Company has elected to take responsibility for assessing compliance
     with a portion of such servicing activity as permitted by Interpretation
     17.06 with respect to the safeguarding of mortgage loan files and related
     documents while held by Vendors who are pursuing loss mitigation or
     recovery actions.

     with a portion of such servicing activity an permitted by Interpretation

     responsibility of one or more Vendors from whom the Company has obtained an
     assertion of management and an accompanying 1122 attestation report;
     however, the Company takes responsibility for specific limited activities
     performed by it.

(8)  The Company obtained an 1122 Report from one of its Vendors, Assurant,
     which disclaimed the portion of the servicing activity performed by

APPENDIX C

1.   Material instances of noncompliance by the Company with respect to the
     Platform:

     a.   Item 1122(d)(2)(vi) with respect to the safeguarding of unissued
          checks.

     b.   Item 1122(d)(4)(vii) with respect to loss mitigation actions being
          conducted in accordance with the requirements set forth in the
          transaction documents.

2.   Remediation efforts related to material instance of noncompliance by the
     Company with respect to the Platform:

     a.   With respect to the criterion set forth in paragraph 1.a. above,
          physical access to restricted areas within the Company's cashiering
          departments was not always appropriate. The Company utilizes safety
          paper blank check stock which cannot be used without access to certain
          secured systems, which have been appropriately controlled. Physical
          access to applicable areas within the cashiering areas has since been
          restricted to ensure that unmailed checks are safeguarded.

     b.   With respect to the criterion set forth in paragraph 1.b. above, the
          Company's Loss Mitigation Plan attached as an exhibit to the pooling
          and servicing agreement on 8 of 10 Platform transactions issued by the
          Company requires borrowers placed on informal forbearance to provide
          documentation showing the existence of a financial hardship and the
          ability to make the payments required under the proposed forbearance
          plan. With respect to these 8 securitizations, no written
          documentation was obtained from borrowers placed on informal
          forbearance plans. The system of record of the Company was documented
          by an authorized servicing personnel based on verbal representation
          from the borrower. With respect to the final 2 Platform transactions
          which closed in 2006 issued by the Company, the Company updated the
          wording in its Loss Mitigation Plan to indicate that verbal
          documentation by the borrower to be received by authorized servicing
          personnel is acceptable. With respect to the 8 other securitization
          transactions, the Company is in the process of doing the same.

3.   No material instances of noncompliance by Vendors were identified by the
     Company.

4.   Remediation efforts related to material instances of noncompliance by
     Vendors identified by the Company - Not Applicable.

5.   No material deficiencies in the Company's policies and procedures to
     monitor Vendors were identified by the Company.

6.   Remediation efforts related to material deficiencies in the Company's
     policies and procedures to monitor vendors - Not Applicable

Other Matters to be Reported:

The Company determined that, due to a programming error in designing a query for
the loans due for escrow analysis, the query did not contain a date field that
resulted in certain escrow accounts not being timely analyzed. Upon the
Company's discovery of the query error, all loans were subsequently analyzed,
however outside the one year time frame. The Company will assess the impact of
this matter on its compliance with Regulation AB servicing criteria for the
Platform as of and for the year ending December 31, 2007.

The Company identified the following instance of noncompliance by Assurant who
provided their separate Regulation AB 1122 compliance report:

          Assurant performs certain activities with respect to the Company's
          Platform under the servicing criterion 1122(d)(4)(xii), however,
          Assurant informed the Company that it could not assert to the
          compliance of their activities with this criterion due to limitations
          in their servicing system, specifically with respect to Assurant's
          ability to accurately track, record and report to the Company portions
          of late payment penalties in connection with insurance payments made
          on behalf of obligors from their escrow accounts. Assurant has
          informed the Company that it is in the process of updating its
          servicing system to remediate this matter.
