  Report of Independent Accountants

  To the Board of Directors and Shareholder of Bank of America, N.A.

  We have examined management's assertion about compliance by the mortgage
  division of Bank of America, N.A. (the "Company"), an operating division of
  Bank of America, N.A., with the minimum servicing standards identified in the
  Mortgage Bankers Association of America's Uniform Single Attestation Program
  for Mortgage Bankers ("USAP") as of and for the year ended December 31, 2003
  included in the accompanying management assertion (see Exhibit 1). Management
  is responsible for the 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
  American Institute of Certified Public Accountants and, accordingly, included
  examining, on a test basis, evidence about the Company's compliance with the
  minimum servicing standards and performing such other procedures as we
  considered necessary in the circumstances. We believe that our examination
  provides a reasonable basis for our opinion. Our examination does not provide
  a legal determination on the Company's compliance with the minimum servicing
  standards.

  In our opinion, management's assertion that the Company complied with the
  aforementioned minimum servicing standards as of and for the year ended
  December 31,2003 is fairly stated, in all material respects.
