The Board of Directors
Wachovia Bank, National Association:


We have examined management's assertion, included in the accompanying management
assertion, 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, 2004. 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, 2004 is fairly stated, in all material respects.
