INDEPENDENT ACCOUNTANTS' REPORT

The Board of Directors
Wells Fargo Home Mortgage:

We have examined management's assertion dated February 25, 2003 that Wells
Fargo Home Mortgage 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, 2002.
Management is responsible for Wells Fargo Home Mortgage's compliance with
those minimum standards.  Our responsibility is to express an opinion on
management's assertion about Wells Fargo Home Mortgage'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 Wells Fargo
Home Mortgage'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 Wells
Fargo Home Mortgage's compliance with the minimum servicing standards.

In our opinion, management's assertion that Wells Fargo Home Mortgage complied
with the aforementioned minimum servicing standard as of and for the year ended
December 31, 2002, is fairly stated, in all material respects.
