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 conducted in accordance with attestation 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 its 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 its 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 based on the criteria set forth in Appendix I. /s/ Deloitte & Touche LLP - --------------------------------------------- February 20, 2004 -8- <page> APPENDIX I MINIMUM SERVICING STANDARDS AS SET FORTH IN THE MORTGAGE BANKERS ASSOCIATION OF AMERICA'S UNIFORM SINGLE ATTESTATION PROGRAM FOR MORTGAGE BANKERS I.
