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

Report of Independent Accountants

Board of Directors
ARCap Servicing, Inc.

We have examined management's assertion, included in the accompanying report
titled Report of Management, that ARCap Servicing, Inc. (the Company) complied
with the minimum servicing standards, as stated in Attachment A, which were
derived from the Mortgage Bankers Association of America's Uniform Single
Attestation Program for Mortgage Bankers (USAP) except, for commercial loan
and multifamily loan servicing, minimum servicing standards V.4. and VI.1.,
which the Mortgage Bankers Association of America has interpreted as
inapplicable to such servicing during the year ended December 31, 2003.
Management is responsible for the Company's compliance with those
requirements. Our responsibility is to express an opinion on management's
assertions about the Company's 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 those requirements 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 specified requirements.

In our opinion, management's assertion, that the Company complied with the
aforementioned requirements during the year ended December 31, 2003, is fairly
stated, in all material respects.
