Independent Accountants' Report

The Board of Directors
Wachovia Bank National Association:

We have examined  management's  assertion, included in the accompanying  report,
that the Commercial Real Estate Servicing Division of Wachovia Bank National
Association (the Bank) complied with the minimum servicing standards set forth
in the Mortgage Bankers Association of America's  ("MBA's") Uniform Single
Attestation  Program for Mortgage Bankers, except for minimum  servicing
standards V.4 and VI.1, which the MBA has interpreted as being inapplicable to
the servicing of commercial and multifamily loans, as of and for the year
ended December 31, 2003.  Management  is  responsible  for the  Bank's
compliance  with  those  minimum  servicing  standards.  Our responsibility is
to express an opinion on management's assertion about the Bank'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 Bank'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 Bank's compliance with
the minimum servicing standards.

In our opinion, management's assertion that the Bank has complied with the
aforementioned  minimum servicing  standards as of and for the year ended
December 31, 2003 is fairly stated, in all material respects.
