2.    Based on my knowledge, with respect to each Trust, the information in
      these 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

      to be provided to the trustee by each servicer under each Agreement for
      inclusion in the related Trust's Distribution Date Statements is included
      in these reports;

4.    I am responsible for reviewing the activities performed by each servicer
      under each Agreement and based upon my knowledge and the annual compliance
      review required under each Agreement, and except as disclosed in the
      reports, each servicer has fulfilled its obligations under each Agreement;

5.    The reports disclose all significant deficiencies relating to each
      servicer's compliance with the minimum servicing standards, based upon the
