                         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.

                      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

               REPORT OF INDEPENDENT ACCOUNTANTS ON MANAGEMENT'S
            ASSERTION ON COMPLIANCE WITH MINIMUM SERVICING STANDARDS
            SET FORTH IN THE UNIFORM SINGLE ATTESTATION PROGRAM FOR
                                MORTGAGE BANKERS

Board of Directors
Specialized Loan Servicing, LLC

We have examined management's assertion about Specialized Loan Servicing,  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. 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 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  Specialized  Loan Servicing,  LLC
complied with the aforementioned  minimum servicing  standards as of and for the
year ended December 31, 2005 is fairly stated, in all material respects.
