responsible for the Company's compliance with those requirements. Our
responsibility is to express an opinion on management's assertion about the

Our examination was conducted in accordance with attestation standards

standards as set forth in the Mortgage Bankers Association of America's Uniform

ended December 31, 2004, the Company complied, in all material respects, with
the minimum servicing standards set forth in the USAP.

As of and for this same period, the Company was insured as a subsidiary of
KeyCorp. As of December 31, 2004, the Company had $100,000,000 fidelity bond
coverage and $100,000,000 errors and omissions coverage.
