Independent Accountants' Report

The Board of Directors
Wells Fargo Home Mortgage, a division of Wells Fargo Bank, N.A.:


We have examined management's assertion, included in the accompanying
Assertion of Management of Wells Fargo Home Mortgage, a division of Wells
Fargo Bank, N.A. (the Company), that 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's compliance based on our examination.


Our examination was conducted 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 the Company complied with the
aforementioned minimum servicing standards as of and for the year ended
December 31, 2004 is fairly stated, in all material respects.
