INDEPENDENT ACCOUNTANTS' REPORT


To Cendant Mortgage Corporation:

     We  have   examined   management's   assertion   about   Cendant   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 December 31, 2002 included
in the accompanying management assertion.  Management is responsible for Cendant
Mortgage  Corporation'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  Cendant  Mortgage  Corporation'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 Cendant Mortgage  Corporation's  compliance
with the minimum servicing standands.

     In our opinion,  management's  assertion that Cendant Mortgage  Corporation
complied with the aforementioned  minimum servicing  standards as of and for the
year ended December 31, 2002 is fairly stated, in all material respects.
