Independent Accountants' Report


The Board of Directors
HomEq Servicing Corporation

We have examined management's assertion, included in the accompanying
Management's Assertion, that Homeq Servicing Corporation (the Company) 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, 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.
