REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors of
Wilshire Credit Corporation:

We have examined management's assertion that Wilshire Credit Corporation, a
wholly owned subsidiary of Merrill Lynch Mortgage Capital Inc., a division of
Merrill Lynch & Co., New York, NY (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 on Minimum
Servicing Standards dated February 27, 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.
