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. /s/ KPMG LLP March 17, 2005 KPMG LLP, a U.S. limited liability partnership, is the U.S. member firm of KPMG International, a Swiss cooperative.

(the Company), that the Company 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 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 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 the Company'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 the Company's compliance with the minimum servicing standards.

(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 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.
