                       Report of Independent Auditors


To the Board of Directors of
Chase Manhattan Mortgage Corporation:


We  have  examined   management's   assertion  about  Chase  Manhattan  Mortgage
Corporation'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, 2004. 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 such 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, 2004 is fairly stated, in all material respects.

             Management's Assertion Concerning Compliance with USAP
                          Minimum Servicing Standards


March 23, 2005

As of and for  the  year  ended  December  31,  2004,  Chase  Home  Finance  LLC
(successor by merger to Chase Manhattan  Mortgage  Corporation)  (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 those
USAP reports for the year ended  December 31, 2004 are available as of March 23,
2005. As of March 23, 2005, the Company has obtained USAP reports for 32% of its
subservicers.  These  subservicers  serviced loans  comprising 90% of the unpaid
principal balance of the Company's Master Servicing Portfolio as of December 31,
2004.  Instances of  non-compliance  noted in the USAP reports received from the
subservicers as of March 23, 2005, 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  policy in the amounts of  $250,000,000  and  $25,000,000,
respectively.

                      Chase Manhattan Mortgage Corporation
                      Subservicers' USAP Report Exceptions


It is the policy of Chase  Manhattan  Mortgage  Corporation  (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, 2004.  As of March 23, 2005,  the Company has obtained and reviewed
USAP reports for 32% of its  subservicers.  These  subservicers  serviced  loans
comprising 90% of the unpaid principal balance of the Company's Master Servicing
Portfolio as of December 31, 2004. The Company noted instances of  noncompliance
included in the USAP reports received as of March 23, 2005, which are summarized
below.



Servicer                                        Exception

Cendant Mortgage  Corporation     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.


North Fork Bancorporation, Inc.   The mortgage interest rate changes on certain
                                  Home Equity Lines of Credit were not adjusted
                                  at the appropriate date in accordance with
                                  the mortgagor's loan documents. This resulted
                                  in the mortgagor being overcharged for the
                                  period from the interest rate change until
                                  the correct effective date, which was the
                                  first day of the following month.


GMAC Mortgage Corporation         There were bank accounts over the course of
                                  several months where the Company was not in
                                  full compliance with USAP requirements as it
                                  related to the preparation of custodial bank
                                  reconciliations within 45 calendar days of
                                  cutoff as well as the resolution of
                                  reconciling items within 90 calendar days of
                                  original identification. The Company
                                  remediated the issues related to the
                                  preparation of custodial bank accounts
                                  reconciliations within 45 calendar days as of
                                  December 31, 2004.

We have  examined the  accompanying  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,  (collectively,  the Company) complied with the

and for the year ended  December 31, 2004.  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' 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  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

IndyMac Bank, F.S.B.


We have examined  management's  assertion,  included in the accompanying  report
titled Report of Management,  that IndyMac Bank, F.S.B, (the Bank) 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  December  31,  2004.   Management  is
responsible for the Bank's  compliance with these  specified  minimum  servicing
standards. Our responsibility is to express an opinion on management's assertion
about the Bank'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  Bank'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  Bank's  compliance  with  the  specified  minimum
servicing standards.

In  our  opinion,  management's  assertion  that  the  Bank  complied  with  the
aforementioned  specified  minimum  servicing  standards  during  the year ended
December 31, 2004, is fairly stated, in all material respects.

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

Management  (the  specific  minimum  servicing  standards)  as set  forth in the

Our  responsibility  is to express an opinion on management's  assertions  about
NCM's compliance based on our examination.

In our opinion, management's assertion that NCM complied with the aforementioned
specified minimum  servicing  standards during the year ended December 31, 2004,
