INDEPENDENT ACCOUNTANTS' REPORT

To the Board of Directors and Stockholder of
EMC Mortgage Corporation:

We have examined the accompanying management assertion that EMC Mortgage
Corporation (the "Company") (a wholly owned subsidiary of The Bear Stearns
Companies Inc.) complied with the minimum servicing standards identified in the
Mortgage Bankers Association of America's Uniform Single Attestation Program for
Mortgage Bankers as of and for the year ended November 30, 2001. Management is
responsible for the Company's compliance with those requirements. 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 and,
accordingly, included examining, on a test basis, evidence about the Company's
compliance with the 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 the
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 November
30, 2001, is fairly stated, in all material respects.

the American Institute of Certified Public Accountants and, accordingly,
included examining, on a test basis, evidence about NCM's compliance with those

compliance with specified requirements.

In our opinion, management's assertion, that NCM complied with the
aforementioned requirements during the year ended December 31, 2001, is fairly
stated, in all material respects.

This report is intended solely for the information and use of the audit
committee, management, Federal Home Loan Mortgage Corporation, Federal National
