Report of Independent Registered Public Accounting Firm

To the Partners of Litton Loan Servicing LP:

We have examined management's assertion that Litton Loan Servicing LP (the
Company) has complied as of and for the year ended December 31, 2004, with its
established minimum servicing standards described in the accompanying Management
Assertion Report dated February 16, 2005. 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 conducted in accordance with attestation standards
established by the American Institute of Certified Public Accountants as adopted
by the Public Company Accounting Oversight Board (United States) and,
accordingly, included examining, on a test basis, evidence about the Company's
compliance with its 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 its 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, 2004 is fairly stated, in all material respects based on the criteria set
forth in Appendix I.
