                      SERIES SET FORTH ON EXHIBIT I HERETO

      I, Gary K. Bettin, a Senior Vice President of Bank of America, N.A.,
certify that:

     1. I have reviewed the annual reports on Form 10-K for the calendar year
        2003 and all monthly current reports on Form 8-K containing a copy of
        the monthly statement to certificateholders (the "Distribution Date
        Statements") delivered pursuant to Section 5.04(b) of the Pooling and
        Servicing Agreements listed on Exhibit I hereto (each, an "Agreement")
        filed in respect of periods included in the year covered by such annual
        reports of the trusts (each, a "Trust") formed pursuant to such
        Agreements;

     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 statements made, in light of the circumstances under which such
        statements were made, not misleading as of the last day of the period
        covered by such annual report;

     3. Based on my knowledge, the distribution or servicing information
        required to be provided to the trustee by the 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 the 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, the servicer has fulfilled its obligations under each
        Agreement;

     5. The reports disclose all significant deficiencies relating to the
        servicer's compliance 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 Agreement that
        is included in these reports; and

     6. In giving the certifications above, I have reasonably relied on
        information provided to me by the following unaffiliated party: The Bank
        of New York.
