                        Independent Accountants' Report

Board of Directors
Countrywide Financial Corporation:

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
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, 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
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, 2004 is fairly  stated,  in all material
respects.

            Report of Independent Registered Public Accounting Firm


Board of Directors and Shareholder
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.

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 Bank's  compliance
with the specified minimum  servicing  standards as of December 31, 2004 and for
the year then ended.  Based on this  evaluation,  we assert that during the year
ended December 31, 2004, the Bank complied,  in all material respects,  with the
specified minimum servicing standards.

As of December  31,  2004 and for the year then ended,  the Bank had in effect a

     related bank clearing accounts within two (2) business days of receipt.

2.   Mortgage  payments made in accordance with the  mortgagor's  loan documents
     shall be posted to the  applicable  mortgagor  records  within two (2)
     business days of receipt.

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

     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

1.   The servicing entity's mortgage loan records shall agree with, or reconcile
     to, the records of mortgagors with respect to the unpaid principal  balance
     on a monthly basis.

2.   Adjustments  on adjustable rate mortgage (ARM) loans shall be computed
     based on the related  mortgage note and any ARM rider.

     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.
