               REPORT OF INDEPENDENT ACCOUNTANTS ON MANAGEMENT'S
           ASSERTION ON COMPLIANCE WITH MINIMUM SERVICING STANDARDS
            SET FORTH IN THE UNIFORM SINGLE ATTESTATION PROGRAM FOR
                               MORTGAGE BANKERS


Board of Directors
Countrywide Credit Industries, Inc.


We have examined management's assertion about Countrywide Credit Industries,
Inc. and Subsidiaries (which includes its wholly-owned subsidiary, Countrywide
Home Loans, Inc.) ("the Company") compliance with the minimum servicing
standards identified in the Mortgage Bankers Association of America's Uniform
Single Attestation Program for Mortgage Bankers (USAP) as of and for the year
ended February 28, 1999 included in the accompanying management assertion.
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 entity's compliance based on our examination.

Our examination was made in accordance with 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 Countrywide Credit Industries,
Inc. and Subsidiaries (which includes wholly-owned subsidiary, Countrywide
Home Loans, Inc.) complied with the aforementioned minimum servicing standards
as of and for the year ended February 28, 1999 is fairly stated, in all
material respects.
