INDEPENDENT ACCOUNTANTS' REPORT ON COMEPLIANCE WITH UNIFORM SINGLE ATTESTATION
PROGRAM FOR MORTGAGE BANKERS

Audit Committee of the Board of Directors
Washington Mutual, Inc.
Seattle, Washington


We have examined management's assertion about Washington Mutual, Inc.'s
(the Company) compliance with the minimum servicing standards identified 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, 2001, included
in the accompanying management assertion. 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 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 Company's compliance with the
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 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, 2001, is fairly stated, in all material respects.
