     We have examined management's  assertion dated February 25, 2004 that Wells

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

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

     In our opinion,  management's  assertion that the Company complied with the
