Report of Independent Auditors

Board of Directors
Aurora Loan Services Inc.

     We have  audited the  accompanying  statements  of  financial  condition of
Aurora Loan Services Inc. (the  "Company") as of November 30, 2001 and 2000, and
the related statements of operations,  stockholder's  equity, and cash flows for
the years then ended.  These financial  statements are the responsibility of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audits.

     We conducted our audits in accordance  with  auditing  standards  generally
accepted in the United States and the standards  applicable to financial  audits
contained in Government Auditing Standards, issued by the Comptroller General of
the United States. Those standards require that we plan and perform the audit to
obtain reasonable  assurance about whether the financial  statements are free of
material  misstatement.  An audit includes  examining on a test basis,  evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

     In our opinion,  the financial statements referred to above present fairly,
in all material  respects,  the financial position a November 30, 2001 and 2000,
and the results of its operations and its cash flows for the year then ended, in
conformity with accounting principles generally accepted in the United States.

     Our  audits  were  conducted  for the  purpose of forming an opinion on the
financial  statements  taken as a whole. The Schedule of GNMA Adjusted Net Worth
and GNMA Required Net Worth,  Schedule of GNMA Required Fidelity Bond and Errors
and Omissions Coverage and Computation of Adjusted Net Worth for Recertification
of  Nonsupervised  Mortgages other than Loan  Correspondents  as of November 30,
2001 are presented  for purposes of  additional  analysis and are not a required
part of the financial  statements.  Such  information  has been subjected to the
auditing procedures applied in our audit of the financial statements and, in our
opinion,  is fairly stated in all material respects in relation to the financial
statements taken as a whole.

     In accordance with Government Auditing  Standards,  we have issued a report
dated December 28, 2001 on our  consideration of the Company's  internal control
over financial  reporting and our tests of its compliance  with certain laws and
regulations. That report is an integral part of an audit performed in accordance
with  Government  Standards and should be read in  conjunction  with this report
when considering the results of our audits.
