covered by this Annual Report, of the Trust;

     2. Based on my knowledge, the information in the Reports, taken as a whole,
does not  contain  any untrue  statement  of a material  fact or omit to state a
material  fact  necessary  to  make  the  statements   made,  in  light  of  the
circumstances  under which such  statements  were made, not misleading as of the
last day of the period covered by this Annual Report;

     3.  Based  on my  knowledge,  the  distribution  or  servicing  information
required  to be  provided  to the  Trustee  by the  Servicers  under  the  Trust

with the terms of the  Servicing  Agreements,  and  except as  disclosed  in the
Reports,  the Servicers have  fulfilled  their  obligations  under the Servicing

     5. The  Reports  disclose  all  significant  deficiencies  relating  to the
Servicer's compliance with the minimum servicing standards based upon the report
provided by an  independent  public  accountant,  after  conducting  a review in
compliance with the Uniform Single  Attestation  Program for Mortgage Bankers or
similar  procedure,  as set forth in the Trust  Agreement,  that is  included in
the Reports.

                         Report of Independent Auditors


To the Board of Directors of
JPMorgan Chase Bank, N.A.:

We have examined  management's  assertion about JPMorgan Chase Bank, N.A.'s (the
"Company")  compliance with the minimum servicing  standards as set forth in the
Mortgage Bankers Association of America's Uniform Single Attestation Program for
Mortgage  Bankers  ("USAP") as of and for the year ended  December 31, 2005. The
Company  has  interpreted  USAP  and  determined  that  USAP  minimum  servicing
standards I.1, I.2, I.3, III.1,  III.5, IV.1, and VII.1 are applicable to master
servicers and are included in the accompanying management assertion (see Exhibit
I).  Management is responsible  for the Company's  compliance with these minimum
servicing standards. Our responsibility is to express an opinion on management's
assertion,  as it relates to the Company's  compliance  with the  aforementioned
minimum  servicing  standards,  based  on  our  examination.   The  Company  has
interpreted USAP and determined that USAP minimum servicing standards I.4, II.1,
II.2, II.3, II.4, III.2,  III.3,  III.4,  III.6, V.1, V.2, V.3, V.4 and VI.1 are
not applicable to master servicers. The Company uses a subservicing organization
to perform the servicing  obligations  subject to servicing standards I.4, II.1,
II.2, II.3, II.4, III.2, III.3, III.4, III.6, V.1, V.2, V.3, V.4 and VI.1 of the
USAP. We did not examine the Company's  compliance with the servicing  standards
referred to in the previous sentence and accordingly,  do not express an opinion
thereon.

Our examination was made in accordance with attestation standards established by
the  American  Institute  of  Certified  Public  Accountants  and,  accordingly,
included  examining,  on a test basis,  evidence about the Company's  compliance
with the minimum servicing  standards and performing such other procedures as we
considered  necessary  in the  circumstances.  We believe  that our  examination
provides a reasonable basis for our opinion.  Our examination does not provide a
legal  determination  on the  Company's  compliance  with the minimum  servicing
standards.

In our  opinion,  management's  assertion  that the  Company  complied  with the
aforementioned  minimum  servicing  standards solely as they relate to standards
I.1,  I.2,  I.3,  III.1,  III.5,  IV.1,  and VII.1 as of and for the year  ended
December 31, 2005 is fairly stated, in all material respects.

                                                                      EXHIBIT I

             Management's Assertion Concerning Compliance with USAP
                          Minimum Servicing Standards


March 29, 2006

As of and for the year ended December 31, 2005,  JPMorgan Chase Bank,  N.A. (the
"Company")  has complied in all  material  respects  with the minimum  servicing
standards set forth in the Mortgage  Bankers  Association  of America's  Uniform
Single Attestation Program for Mortgage Bankers ("USAP") that we have determined
are applicable to master servicers. We have interpreted USAP and determined that
minimum servicing  standards I.1, I.2, I.3, III.1, III.5, IV.1, and VII.1 as set
forth in USAP are applicable to master servicers.  We have also interpreted that
USAP minimum  servicing  standards I.4, II.1, II.2, II.3,  II.4,  III.2,  III.3,
III.4,  III.6,  V.1,  V.2,  V.3,  V.4 and  VI.1  as set  forth  in USAP  are not
applicable  to master  servicers;  for these  minimum  servicing  standards  the
Company relies on the performance of its  subservicers.  This assertion  relates
specifically to the Company's Master Servicing Portfolio.

It is  the  Company's  policy  to  obtain  and  review  USAP  reports  from  the
independent  auditors of its  subservicers on an annual basis.  Not all of these
USAP reports for the year ended  December 31, 2005 are available as of March 29,
2006. As of March 29, 2006, the Company has obtained USAP reports for 36% of its
subservicers.  These  subservicers  serviced loans  comprising 92% of the unpaid
principal balance of the Company's Master Servicing Portfolio as of December 31,
2005. Instances of  non-compliance  noted in the USAP reports  received from the
subservicers as of March 29, 2006, have been included in Exhibit II hereto.

As of and for this same  period,  the  Company had in effect  fidelity  bond and
errors and omissions  policies in the amounts of $250,000,000  and  $25,000,000,
respectively.

                      Subservicers' USAP Report Exceptions


It is the policy of JPMorgan Chase Bank,  N.A. (the "Company") to obtain Uniform
Single  Attestation  Program for  Mortgage  Bankers  ("USAP")  reports  from the
independent  auditors of its  subservicers as of and for the year ended December
31,  2005.  As of March 29, 2006,  the Company has  obtained  and reviewed  USAP
reports  for  36%  of  its  subservicers.   These  subservicers  serviced  loans
comprising 92% of the unpaid principal balance of the Company's Master Servicing
Portfolio as of December 31, 2005. The Company noted instances of  noncompliance
included in the USAP reports received as of March 29, 2006, which are summarized
below.

        Servicer                               Exception
       ----------                             -----------

Ocwen Loan Servicing, LLC        The Company did not comply with the requirement
                                 to   prepare   custodial   bank   account
                                 reconciliations  and   to  resolve  reconciling
                                 items   within  90  calendar  days   of   their
                                 original  identification  as specified by their
                                 minimum servicing standards.

                                 Certain ARM  loans serviced by the Company were
                                 transferred  in  with  an  incorrect  look back
                                 date due to errors in prior  servicer  records.
                                 These  certain   loans   had   ARM  adjustments
                                 shortly  after servicing transfer, but prior to
                                 the  Company  receiving  the  related  mortgage
                                 documents  from  the  prior  servicer. When the
                                 Company  received  the  mortgage  documents and
                                 these errors  were  identified, the Company did
                                 not adjust the principal and  interest  payment
                                 amount.   The  Company  has  subsequently  made
                                 adjustments  to   their  procedures  when  they
                                 identify  an error  in  prior  servicer data to
                                 analyze  the  effect  on the customer's account
                                 and make the appropriate adjustment.

North Fork Bancorporation, Inc.  The Company did not comply with the requirement
                                 to  prepare   custodial   bank   account
                                 reconciliations  within  45 calendar days after
                                 the cutoff date and  the requirement to resolve
                                 reconciling  items  within  90 calendar days of
                                 their original identification as  specified  by
                                 their  minimum  servicing  standards.  For  the
                                 month  ended  December 31, 2005,  all custodial
                                 bank  reconciliations  had  been  completed and
                                 reviewed on a timely basis.

PHH Mortgage Corporation         The   Company   completed  all  custodial  bank
                                 account  reconciliations  within 60 days of the
                                 cutoff  date,  however  did  not  complete  all
                                 reconciliations within 45 days of the cutoff as
                                 specified by the minimum  servicing  standards.
                                 As such, the Company has determined that it was
                                 materially  non-compliant  with the requirement
                                 to   prepare   custodial   bank   account
                                 reconciliations within 45 days after the cutoff
                                 date.

                                 During  the  year ended December  31, 2005, the
                                 Company  determined   it   was   materially
                                 non-compliant with  the  requirement to resolve
                                 reconciling items resulting from custodial bank
                                 account reconciliations within 90 calendar days
                                 as   specified   by   the   minimum   servicing
                                 standards.

            Report of Independent Registered Public Accounting Firm

Member
Aurora Loan Services LLC

We have examined  management's  assertion,  included in the accompanying  report
titled  Report of  Management,  that Aurora Loan  Services  LLC (the  "Company")
complied with the  servicing  standards  identified in Exhibit A (the  specified
minimum  servicing  standards) to the Report of  Management  as set forth in the
Mortgage Bankers Association of America's Uniform Single Attestation Program for
Mortgage  Bankers (USAP) during the year ended November 30, 2005.  Management is
responsible for the Company's  compliance with those specified minimum servicing
standards. Our responsibility is to express an opinion on management's assertion
about the Company's compliance based on our examination.

Our  examination  was  made in  accordance  with  standards  established  by the
American  Institute of Certified Public Accountants and,  accordingly,  included
examining,  on a test basis,  evidence about the Company's  compliance  with the
specified minimum servicing standards and performing such other procedures as we
considered  necessary  in the  circumstances.  We believe  that our  examination
provides a reasonable basis for our opinion.  Our examination does not provide a
legal  determination  on the Company's  compliance  with the  specified  minimum
servicing standards.

In our  opinion,  management's  assertion  that the  Company  complied  with the
aforementioned  specified  minimum  servicing  standards  during  the year ended
November 30, 2005, is fairly stated, in all material respects.

                              Report of Management


We, as members of management of Aurora Loan  Services LLC (the  "Company"),  are
responsible  for  complying  with  the  servicing  standards  identified  in the
attached Exhibit A (the "specified minimum servicing standards") as set forth in
the Mortgage Bankers Association of America's Uniform Single Attestation Program
for Mortgage  Bankers  ("USAP").  We are also  responsible for  establishing and
maintaining  effective  internal  control over  compliance  with these specified
minimum  servicing  standards.  We have performed an evaluation of the Company's
compliance  with the specified  minimum  servicing  standards as of November 30,
2005 and for the year then  ended.  Based on this  evaluation,  we  assert  that
during the year ended November 30, 2005, the Company  complied,  in all material
respects, with the specified minimum servicing standards.

As of November 30, 2005 and for the year then ended, the Company had in effect a
fidelity bond in the amount of $110,000,000  and an errors and omissions  policy
in the amounts of $150,000,000.

                                                                   ----------

               b.   be prepared  within  forty-five (45) calendar days after the

                    account is reconciled  every  month.  It  may, or  may  not,
                    coincide with a prescribed investor reporting date but shall
                    be consistent from period to period;

               c.   be reviewed  and  approved by  someone other than the person
                    who prepared the reconciliation; and

               d.   document explanations for reconciling items. These
                    reconciling items shall be resolved within ninety (90)
                    calendar days of their original identification.

     2.  Funds of the servicing entity shall be advanced in cases where there is

         depository institution in trust for the applicable investor.

     4.  Escrow  funds  held in trust for a  mortgagor  shall be returned to the

         documents  shall be  posted to the applicable mortgagor  records within

     3.  Mortgage payments shall be allocated to principal, interest, insurance,
         taxes or other escrow  items in  accordance with  the  mortgagor's loan
         documents.

     4.  Mortgage payments identified as loan  payoffs  shall  be  allocated  in
         accordance with the mortgagor's loan documents.

III. Disbursements

     1.  Disbursements  made  via  wire  transfer on  behalf  of  a mortgagor or
         investor shall be made only by authorized personnel.

     2.  Disbursements made on behalf of a mortgagor or investor shall be posted
         within two (2) business days to the mortgagor's  or investor's  records
         maintained by the servicing entity.

     3.  Tax and insurance payments shall be made on or  before  the  penalty or
         insurance  policy  expiration  dates, as  indicated  on  tax bills  and
         insurance premium notices, respectively, provided that such support has
         been received by the  servicing  entity at least thirty (30) calendar
         days prior to these dates.

     4.  Any late payment  penalties paid in conjunction with the payment of any
         tax bill or insurance  premium notice shall  be paid from the servicing
         entity's  funds  and not  charged to  the mortgagor,  unless  the  late
         payment was due to the mortgagor's error or omission.

     5.  Amounts remitted to investors per the servicer's investor reports shall
         agree with cancelled checks, or  other  form  of  payment, or custodial
         bank statements.

     6.  Unissued  checks  shall  be  safeguarded so  as to prevent unauthorized
         access.

IV.  Investor Accounting and Reporting

     1.  The servicing  entity's investor reports shall agree with, or reconcile
         to, investors'  records  on  a  monthly  basis as  to the total  unpaid
         principal balance and number of loans serviced by the servicing entity.

V.   Mortgagor Loan Accounting

         in accordance with the applicable state laws.

VI.  Delinquencies

     1.  Records documenting collection efforts  shall be maintained  during the
         period a loan is in default and shall be undated at least monthly. Such
         records shall describe the entity's activities in monitoring delinquent
         loans including, for example, phone calls, letters and mortgage payment
         rescheduling plans in cases where the delinquency  is deemed  temporary
         (i.e., illness or unemployment).

VII. Insurance Policies

     1.  A fidelity bond and errors  and omissions  policy shall be in effect on
         the servicing entity  throughout the reporting  period in the amount of
         coverage represented to investors in management's assertion.

                        Independent Accountants' Report

The Board of Directors
Countrywide Financial Corporation:

We have examined management's assertion, included in the accompanying Management
Assertion,  that Countrywide Financial  Corporation and subsidiaries,  including
its  wholly-owned   subsidiary,  Countrywide  Home  Loans,  Inc.  ("CHL"),   and
Countrywide  Home Loans  Servicing,  L.P.,  a  wholly-owned  subsidiary  of CHL,
(collectively,  the "Company") complied with the minimum servicing standards set
forth  in  the  Mortgage  Bankers   Association  of  America's   Uniform  Single
Attestation  Program for  Mortgage  Bankers  (USAP) as of and for the year ended
December 31, 2005.  Management is responsible for the Company's  compliance with
those minimum servicing  standards.  Our responsibility is to express an opinion
on  management's   assertion  about  the  Company's   compliance  based  on  our
examination.

Our  examination  was  conducted  in  accordance  with   attestation   standards
established  by the  American  Institute of Certified  Public  Accountants  and,
accordingly,  included examining,  on a test basis, evidence about the Company's
compliance with the minimum servicing  standards  specified above and performing
such other  procedures  as we  considered  necessary  in the  circumstances.  We
believe that our examination  provides a reasonable  basis for our opinion.  Our
examination does not provide a legal  determination on the Company's  compliance
with the minimum servicing standards.

In our opinion,  management's  assertion that Countrywide  Financial Corporation
and subsidiaries, including its wholly-owned subsidiary, Countrywide Home Loans,
Inc.  ("CHL"),  and  Countrywide  Home Loans  Servicing,  L.P.,  a  wholly-owned
subsidiary of CHL, complied with the aforementioned  minimum servicing standards
as of and for year ended  December  31, 2005 is fairly  stated,  in all material
respects.

                       Report of Independent Accountants

To the Board of Directors and Shareholder
of GMAC Mortgage Corporation:

We have examined management's  assertion about GMAC Mortgage Corporation and its
subsidiaries  (the "Company")  compliance with the minimum  servicing  standards
identified  in the Mortgage  Bankers  Association  of America's  Uniform  Single
Attestation  Program for Mortgage  Bankers ("USAP") as of and for the year ended
December 31, 2005 included in the accompanying management assertion (see Exhibit
I).  Management is responsible  for the Company's  compliance with those minimum
servicing standards. Our responsibility is to express an opinion on management's
assertion about the Company's compliance based on our examination.

Our  examination  was  performed  in  accordance  with   attestation   standards
established  by the  American  Institute of Certified  Public  Accountants  and,
accordingly,  included examining,  on a test basis, evidence about the Company's
compliance  with the  minimum  servicing  standards  and  performing  such other
procedures as we considered necessary in the circumstances.  We believe that our
examination  provides a reasonable  basis for our opinion.  Our examination does
not provide a legal  determination on the Company's  compliance with the minimum
servicing standards.

In our  opinion,  management's  assertion  that the  Company  complied  with the
aforementioned minimum servicing standards as of and for the year ended December
31, 2005 is fairly stated, in all material respects.

                        Report of Independent Accountants


Board of Directors
National City Mortgage Co.

We have examined  management's  assertion,  included in the accompanying  report
titled Report of Management, that National City Mortgage Co. (NCM) complied with
the  minimum  servicing  standards  identified  in  Exhibit  A to the  Report of
Management  (the  specific  minimum  servicing  standards)  as set  forth in the
Mortgage Bankers Association of America's Uniform Single Attestation Program for
Mortgage  Bankers  during  the  year-ended  December  31,  2005.  Management  is
responsible for NCM's compliance with the specified minimum servicing standards.
Our  responsibility  is to express an opinion on management's  assertions  about
NCM's compliance based on our examination.

Our examination was made in accordance with attestation standards established by
the Public Company Accounting Oversight Board (United States) and,  accordingly,
included  examining,  on a test basis,  evidence about NCM's compliance with the
specified minimum servicing standards and performing such other procedures as we
considered  necessary  in the  circumstances.  We believe  that our  examination
provides a reasonable basis for our opinion.  Our examination does not provide a
legal  determination  on  NCM's  compliance  with  specified  minimum  servicing
standards.

In our opinion, management's assertion that NCM complied with the aforementioned
specified minimum  servicing  standards during the year ended December 31, 2005,
is fairly stated, in all material respects.

4.   Any late payment  penalties paid in conjunction with the payment of any tax

     servicing entity  throughout the reporting period in the amount of coverage
     represented to investors in management's assertion.

                                ---------------



REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To PHH Mortgage Corporation:

We have examined PHH Mortgage  Corporation's (the "Company") compliance with its
established   minimum   servicing   standards   described  in  the  accompanying
Management's  Assertion,  dated  February 28, 2006, as of and for the year ended
December 31, 2005.  Management is responsible  for compliance with those minimum
servicing  standards.  Our  responsibility  is to  express  an  opinion  on the
Company's compliance based on our examination.

Our examination was conducted in accordance with attention standards established
by the  American  Institute of Certified  Public  Accountants  as adopted by the
Public Company Accounting Oversight Board and, accordingly,  included examining,
on a test  basis,  evidence  about the  Company's  compliance  with its  minimum
servicing  standards  and  performing  such other  procedures  as we  considered
necessary  in the  circumstances.  We believe  that our  examination  provides a
reasonable  basis for our  opinion.  Our  examination  does not  provide a legal
determination on the Company's compliance with its minimum servicing standards.

Our examination disclosed the following instance of material  noncompliance with
the  reconciliation of custodial bank accounts  applicable to the Company during
the  year  ended  December  31,  2005.  The  Company  did not  comply  with  the
requirement to prepare custodial bank account reconciliations within 45 calendar
days after the cutoff  date and the  requirement  to resolve  reconciling  items
within 90 calendar days of their original  identification  as specified by their
minimum servicing standards.

In our opinion, except for the material noncompliance described in the preceding
paragraph,   the  Company  complied,   in  all  material   respects,   with  the
aforementioned minimum servicing standards as of and for the year ended December
31, 2005, as set forth in Appendix I.
