 The Board of Directors
 First Horizon Home Loan Corporation and Subsidiaries:

 We have examined managements assertion, included in the accompanying
 management assertion letter, that First Horizon Home Loan Corporation
 and its wholly owned subsidiary, First Tennessee Mortgage Services,
 Inc., which includes a consolidated investment in FH-FF Mortgage
 Services, L.P. (the Company), complied with the minimum servicing
 standards set forth in the Mortgage Bankers Association of Americas
 Uniform Single Attestation Program for Mortgage Bankers (USAP) as of
 and for the year ended December 31, 2005.  Management is responsible
 for the Companys compliance with those minimum servicing standards.
 Our responsibility is to express an opinion on managements assertion
 about the Companys compliance based on our examination.

 Our examination was conducted in accordance with the attestation
 standards established by the American Institute of Certified Public
 Accountants and, accordingly, included examining, on a test basis,
 evidence about the Companys 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 Companys
 compliance with the minimum servicing standards.

 In our opinion, managements assertion that the Company complied with
 the aforementioned minimum servicing standards as of and for the year
 ended December 31, 2005, is fairly stated, in all material respects.

        premiums, if applicable, have been paid and are in full force
        and effect.

 3.	Properties are adequately insured and your interest, as
        Mortgagee, is properly provided for in the mortgage clause.
        This includes both flood and hazard insurance.

 4.	For those loans being escrowed for the payment of taxes and
        insurance, sufficient amounts are being collected monthly to
        provide for payment of future items.

 5.	Property inspections have been completed according to the
        provisions of our servicing agreement, if applicable.

 6.	All other provisions of the servicing agreements have been
        adhered to.

        that are deemed to be material in nature, such exception(s)
        will be recited in an Exhibit attached hereto and accompanied
        by an explanation thereof. In the event, no Exhibit is attached
        hereto it is to be presumed that no exceptions of a material
        nature to the foregoing exist.
