Report on Management's Assertion on
Compliance with the Specified Minimum Servicing Standards Set Forth in the
Uniform Single Attestation Program for Mortgage Bankers

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.
