Independent Accountants' Report

The Board of Directors
North Fork Bancorporation Inc.:

We have examined management's assertion, included in the accompanying
Management Assertion, that GreenPoint Mortgage Funding, Inc., a wholly owned
subsidiary of North Fork Bancorporation, 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)
as of and for the year ended December 31, 2004.  Management is responsible
for Greenpoint Mortgage Funding, Inc.'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 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 GreenPoint
Mortgage Funding, Inc.'s compliance with the minimum servicing standards
specified above 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 GreenPoint Mortgage Funding, Inc.'s compliance with the
minimum servicing standards.

Management identified the following material noncompliance with minimum
servicing standards over mortgage payments as of and for the year ended
December 31, 2004.  The mortgage interest rate changes on certain Home Equity
Lines of Credit were not adjusted at the appropriate date in accordance with
the mortgagor's loan documents.  This resulted in the mortgagor being
overcharged for the period from the interest rate change until the corrective
effective date, which was the first day of the following month.

In our opinion, except for the material noncompliance described in the third
paragraph, management's assertion that GreenPoint Mortgage Funding, Inc.
complied with the aforementioned minimum servicing standards as of and for
the year ended December 31, 2004 is fairly stated, in all material respects.

Management's Assertion
March 17, 2005

As of and for the year ended December 31, 2004, GreenPoint Mortgage Funding,
Inc. (the "Company") has complied in all material respects with the minimum
servicing standards set forth in the Mortgage Bankers association of
America's Uniform Single Attestation Program for Mortgage Bankers, except
for the following:

	In certain circumstances, the mortgage interest rate changes on certain
      Home Equity Lines of Credit were not adjusted at the appropriate date in
      accordance with the mortgagor's loan documents.  This resulted in the
      mortgagor being overcharged for the period from the interest rate change
      until the corrective effective date, which was the first day of the
      following month.  This error was identified by Management and the
      systemic issue that caused the incorrect calculation of interest was
      resolved prior to the issuance of this letter.

As of and for the year ended December 31, 2004, the Company had in effect a
fidelity bond in the amount of $25,000,000 for a single loss limit and an
aggregate limit of liability of $50,000,000 and an errors and omissions policy
in the amount of $25,000,000 for a single loss limit and no aggregate limit of
liability.
