INDEPENDENT ACCOUNTANTS' REPORT

Board of Directors
Wilshire Credit Corporation

     We  have  examined  Wilshire  Credit   Corporation's  (the  "Company"),   a
wholly-owned  subsidiary of Wilshire Financial Services Group, Inc.,  compliance
with its established  minimum servicing  standards described in the accompanying
Management's  Assertion on Minimum Servicing Standards,  dated March 26, 2004 as
of and for the year ended December 31, 2003.  Management is responsible  for the
Company's compliance with those minimum servicing standards.  Our responsibility
is to express an opinion on the Company'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 its  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 its minimum
servicing standands.

     Our examination  disclosed the following  material  noncompliance  with the
Company's  established minimum servicing standards set forth in Appendix I, Item
V.2,  relating to interest rate  adjustments on adjustable rate mortgage ("ARM")
loans. In two of the  thirty-five ARM loans selected for testing,  the Company's
calculations  of the interest rate  adjustments  were not in accordance with the
related mortgage notes and any ARM rider.

     In our  opinion,  except for the  material  noncompliance  described in the
preceding paragraph,  the Company complied,  in all material respects,  with the
aforementioned minimum servicing standards as of and for the year ended December
31, 2003 as set forth in Appendix I.

                        MANAGEMENT'S ASSERTION ON
                        MINIMUM SERVICING STANDARDS

As of and for the year ended December 31, 2003,  Wilshire Credit Corporation has
complied,  in all  material  respects,  (except to the extent as decribed in the
following  paragraph) with Wilshire  Credit  Corporation's  established  minimum
servicing  standards for residential  mortgages loans as set forth in Appendix I
(the "Standards").  The Standards are based on the Mortgage Banker's Association
of America's Uniform Single Attestation Program for Mortgage Bankers.

Our auditors have  concluded that 2 out of 35 ARM loans selected for testing had
adjustments  that were not in accordance with the related mortgage notes and any
ARM rider.

As of and for this same period, the Wilshire Credit Corporation had in effect an
errors  and  omissions  policy in the  amount  of  $5,000,000.  Wilshire  Credit
Corporation  had in effect a  fidelity  bond in the amount of  $10,000,000  from
January 1, 2003 through September 30, 2003 and in the amount of $20,000,000 from
October 1, 2003 through December 31, 2003.
