*  A Mortgage Loan is considered delinquent in a given month when a payment
due on the first day of the prior month has not been made on or before the
first day of such prior month.

**  Reflects the outstanding principal balance of the Mortgage Pool after the
application of all December 01, 2002 scheduled payments and November 01, 2002
unscheduled payments on the mortgage loans.

***  Reflects outstanding principal balance of delinquent mortgage loans as of
November 31, 2002.

Trading Factor, calculated as of distribution date : 0.71726105.
By multiplying this factor by the original balance of the Mortgage Pool as of
the Cut-Off Date, current outstanding balance of the Mortgage Pool (after
application of scheduled payments up to and including December 01, 2002, and
unscheduled prepayments in months prior to December ) can be calculated.
