Report of Independent Auditors

To the Board of Directors and Stockholders of Irwin Financial Corporation:

We have examined management's assertion about Irwin Financial Corporation and
its subsidiaries, including Irwin Home Equity (the "Company") 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, 2003 included in the accompanying
management assertion (see Exhibit I). 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 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 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 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, 2003 is fairly stated, in all material respects.
