Report on Management's Assertion on Compliance
With Minimum Servicing Standards Set Forth in the
Uniform Single Attestation Program for Mortgage Bankers

Report of Independent Accountants

Board of Directors
ABM AMRO North America, Inc.

We have examined  management's  assertion,  included in the accompanying  report
titled  Report of  Management,  that except for  noncompliance  with the minimum
servicing   standard   for   custodial   bank  and  related   clearing   account
reconciliations, ABN AMRO Mortgage Group, Inc. (AAMG, wholly owned subsidiary of
ABN AMRO North America,  Inc.) complied with the minimum servicing standards set
forth  in  the  Mortgage  Bankers   Association  of  America's   Uniform  Single
Attestation  Program for Mortgage  Bankers (USAP) during the year ended December
31,  2001.   Management  is  responsible   for  AAMG's   compliance  with  those
requirements.  Our  responsibility  is to express  an  opinion  on  management's
assertions about AAMG's compliance based on our examination.

Our examination was made in accordance with attestation standards established by
the  American  Institute  of  Certified  Public  Accountants  and,  accordingly,
included examining, on a test basis, evidence about AAMG's compliance with those
requirements 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
AAMG's compliance with specified requirements.

In our  opinion,  management's  assertion,  that except for  noncompliance  with
custodial bank and related clearing account reconciliations,  AAMG complied with
the  aforementioned  requirements  during the year ended  December 31, 2001,  is
fairly stated, in all material respects.

This  report is  intended  solely  for the  information  and use of the board of
directors,  management,  and AAMG's private  investors and is not intended to be
and should not be used for anyone other than these specified parties.

INDEPENDENT AUDITORS' REPORT ON AGREEMENTS
WITH THE CHASE MANHATTAN BANK

Board of Directors
Washington Mutual Bank, FA

We have audited, in accordance with auditing standards generally accepted in the
United States of America,  the consolidated  statement of financial condition of
Washington  Mutual  Bank,  FA  and  subsidiaries  (including  Washington  Mutual
Mortgage  Securities  Corp.  (WMMSC)) as of December 31,  2001,  and the related
consolidated  statements  of  income,  stockholder's  equity  and  comprehensive
income,  and of cash flows for the year then  ended,  and have issued our report
thereon  dated  February  19, 2002  (March 1, 2002,  as to  Note2)(which  report
expresses an unqualified opinion and includes an explanatory  paragraph relating
to the  adoption  of  Statement  of  Financial  Accounting  Standards  No.  133,
Accounting for Derivative  Instruments and Hedging  Activities,  as amended,  on
January 1, 2001).

In connection  with our audit,  nothing came to our attention  that caused us to
believe that WMMSC failed to comply with the terms,  covenants,  provisions,  or
conditions  of the  sections  of the  agreements  between  WMMSC  and The  Chase
Manhattan Bank (Chase), as listed in the accompanying schedule,  insofar as they
relate to financial and accounting matters.  However, our audit was not directed
primarily toward obtaining knowledge of noncompliance.

This  report is  intended  solely  for the  information  and use of the Board of
Directors,  management  of  Washington  Mutual  Bank FA, and  Chase,  and is not
intended  to be and  should not be used by anyone  other  than  these  specified
parties.
