                         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.

             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.

It is the policy of JPMorgan Chase Bank,  N.A. (the "Company") to obtain Uniform

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.

                                 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 Accountants

Board of Directors
LaSalle Bank Corporation

We have examined  management's  assertion,  included in the accompanying  report
titled Report of Management,  that ABN AMRO Mortgage Group, Inc. (AAMG, a wholly
owned  subsidiary  of LaSalle  Bank  Corporation)  complied  with the  servicing
standards  identified in Exhibit A to the Report of Management  (the  "specified
minimum servicing  standards") as set forth in the Mortgage Bankers  Association
of America's  Uniform  Single  Attestation  Program for Mortgage  Bankers (USAP)
during the year ended December 31, 2005.  Management is  responsible  for AAMG's
compliance with those specified minimum servicing standards.  Our responsibility
is to express an opinion on management's assertion about AAMG'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  AAMG'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 AAMG's  compliance with the specified  minimum servicing
standards.

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

      Forth in the Uniform Single Attestation Program for Mortgage Bankers

owned subsidiary of LaSalle Bank Corporation) 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  AAMG's  compliance  with  the  specified  minimum
servicing  standards as of December 31, 2005 and for the year then ended.  Based
on this evaluation,  we assert that during the year ended December 31, 2005, the
Bank complied,  in all material  respects,  with the specified minimum servicing
standards.

             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

         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.

         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.

             Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholder
of Bank of America, N.A.:

We have examined management's assertion concerning the mortgage division of Bank
of  America,  N.A.'s (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's  Assertion
Concerning  Compliance  with USAP Minimum  Servicing  Standards (see Exhibit 1).
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  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
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 Auditors


To the Board of Directors and Stockholder
of Chase Home Finance LLC:

We have  examined  management's  assertion  about Chase Home Finance  LLC's (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 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 as of and for the year ended December
31, 2005 is fairly stated, in all material respects.

To the Board of Directors and Stockholder
of JPMorgan Chase Bank, National Association:


We have examined  management's  assertion  about JPMorgan  Chase Bank,  National

Attestation  Program  for  Mortgage  Bankers  ("USAP")  solely as they relate to
standard VII, Insurance Policies (the "Applicable Standard"),  as of and for the
year ended December 31,2005 included in the accompanying  management  assertion.
Management is  responsible  for the  Company's  compliance  with the  Applicable
Standard.  Our responsibility is to express an opinion on management's assertion
about the Company's compliance,  solely as it relates to the Applicable Standard
based on our examination. The Company uses subservicing organizations to perform
the servicing  obligations  subject to minimum servicing standards I-VI of USAP.
We did not examine the Company's  compliance  with  standards  I-VI of USAP 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  Applicable  Standard  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 Applicable Standard.

In our  opinion,  management's  assertion  that the  Company  complied  with the
Applicable Standard solely as it relates to standard VII, Insurance Policies, as
of and for the year ended  December  31,2005 is fairly  stated,  in all material
respects.

examination.

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


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors of Fifth Third Mortgage Company:

We have examined  management's  assertion that Fifth Third Mortgage Company (the
"Company") has complied as of and for the year ended December 31, 2005, with its
established minimum servicing standards for residential mortgage loans described
in the accompanying  Management's  Assertion dated March 9, 2006.  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,  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.

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 based on the criteria set
forth in Appendix I.

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.

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


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.
