INDEPENDENT ACCOUNTANTS' REPORT

Board of Directors and Stockholder
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, 2002.
Management is responsible for the Company's compliance with those requirements.
Our responsibility is to express an opinion on management'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, 2002 is fairly stated, in all material respects.

Management, that National City Mortgage Co. (NCM) complied with the minimum

those requirements.  Our responsibility is to express an opinion on
management's assertions about NCM'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 NCM's
compliance with those requirements and performing such other procedures as we

provides a reasonable basis for our opinion.  Our examination does not provide
a legal determination on NCM's compliance with specified requirements.

In our opinion, management's assertion, that NCM complied with the
aforementioned requirements for the year ended December 31, 2002, is fairly
stated, in all material respects.

This report is intended solely for the information and use of the audit
