Report of Independent Accountants

To Option One Mortgage Corporation

We have examined management's  assertion about Option One Mortgage Corporation's
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  April 30, 2000 included  in the
accompanying  management  assertion.  Management is  responsible  for Option One
Mortgage  Corporation's  compliance with those minimum servicing standards.  Our
responsibility  is to express and 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 Option One Mortgage  Corporation's
compliance with the minimum servicing standards 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 Option One Mortgage  Corporation's  compliance with the
minimum servicing standards.

In our opinion,  management's  assertion  that Option One  Mortgage  Corporation
complied with the aforementioned  minimum servicing  standards as of and for the
year ended April 30, 2000 is fairly stated, in all material respects.
