    We have examined the accompanying management assertion that CapMark

    set forth in the Mortgage Bankers Association of America's ("MBA's")
    Uniform Single Attestation Program for Mortgage Bankers ("USAP") as of and

    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 standards established by the

    examining, on a test basis, evidence about the Company's compliance with the

    considered necessary in the circumstances.  We believe that our examination
    provides a reasonable basis for our opinion.  Our  examination  does not
