      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.
