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 correct
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.

We have examined management's assertion about M&T Mortgage Corporation's (the

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

standards.

In our opinion, management's assertion that the Company complied with the

Management 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 correct 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.
