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 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 of 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, 2002 is fairly stated, in all material respects. 	/s/ Deloitte & Touche 	January 10, 2003 	99.4 Management Assertion on USAP Litton Loan Servicing LP An Affiliate of C-Bass 4828 Loop Central Drive, Suite 600 Houston, TX 77081 Telephone (713) 960-9676 Fax 	 (713) 966-8830 January 10, 2003 As of December 31, 2002, Litton Loan Servicing LP (the Company) has complied in all material respects with the minimum servicing standards set forth in the Mortgage Bankers Association of America's Uniform Single Attestation Program for Mortgage Bankers. As of and for this same period, Litton Loan Servicing LP had in effect a fidelity bond in the amount of $15,000,000 and an errors and omissions policy in the amount of $15,000,000. In January 2003, the Company identified certain custodial accounts that had not been reconciled timely during the year ended December 31, 2002.
