REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors of
Washington Mutual Bank and Subsidiaries

We have examined management's assertion that Washington Mutual Bank and
Subsidiaries (the "Company") has complied as of and for the year ended December
31, 2005, with its established minimum servicing standards described in the
accompanying Management's Assertion, dated March 10, 2006. 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, 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, 2005, is fairly stated, in all material respects based on the criteria set
forth in Appendix I.
