Report of Independent Registered Public Accounting Firm


To the Board of Directors and Stockholder of
EMC Mortgage Corporation


We have examined EMC Mortgage Corporation's (the "Company") (a wholly owned
subsidiary of The Bear Stearns Companies Inc.) compliance with its established
minimum servicing standards described in the accompanying Management's
Assertion dated February 24, 2005, as of and for the year ended November 30,
2004. 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.


Our examination disclosed the following material noncompliance in regards to
resolving reconciling items within ninety (90) calendar days of their original
identification, applicable to the Company during the year ended November 30,
2004. The reconciliations in three of the twenty custodial bank accounts
selected for testing included twenty three reconciling items which were
resolved after 90 calendar days from their original identification.


In our opinion, except for the material noncompliance described in the
preceding paragraph, the Company complied, in all material respects, with the
aforementioned minimum servicing standards as of and for the year ended
November 30, 2004 based on the criteria set forth in Appendix A.
