  2.  Based
        on
        my knowledge, the information in the Reports, taken as a whole, does not
        contain
        any untrue statement of a material fact or omit to state a material fact
        necessary to make the statements made, in light of the circumstances under

        the master servicer and the special servicer have fulfilled their
        obligations under the Pooling and Servicing Agreement; and
  5.  The
        Reports disclose all significant deficiencies relating to the compliance
        of the
        master servicer and the special servicer with the minimum servicing standards
        based upon the report provided by an independent public accountant, after
        conducting a review in compliance with the Uniform Single Attestation Program
        for Mortgage Bankers or similar procedure, as set forth in the Pooling and
        Servicing Agreement, that is included in the Reports.
