INDEPENDENT AUDITORS' REPORT

To the Partners of
        Litton Loan Servicing LP:

     We have examined  management's  assertion  about Litton Loan Servicing LP's
(the "Company")  compliance 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 December 31, 2000, 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  Company's
compliance based on our examination.

     Our examination  was made in accordance  with standards  established by the
American  Institute of Certified Pubic  Accountants and,  accordingly,  included
examining, on a test basis, evidence about the Company's compliance with 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 of 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 December
31, 2000 is fairly stated, in all material respects.
