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
specified minimum servicing standards and performing such other procedures as we
considered necessary in the circumstances. We believe that our examination
