Transaction Overview (Cont.)

Collateral:	The Mortgage Loans will consist of 30 year adjustable rate loans with an expected aggregate principal balance $[734,470,724], subject to a 5% variance.

At the end of the initial fixed-rate period the mortgage rate on each Mortgage Loan will adjust based on an index plus the related margin. For approximately 97.6% of the Mortgage Loans the "Mortgage Index" for the mortgage rates is the twelve-month average monthly yield on U.S. Treasury Securities adjusted to a constant maturity of one-year, as published by the Federal Reserve Board in the Federal Reserve Statistical Release "Selected Interest Rates (H-15)" (1-year MTA"). For the remaining Mortgage Loans the "Mortgage Index" for the mortgage rates is based on other indices including COFI and LIBOR.

Credit Enhancement:	Credit Enhancement for the Certificates will be provided by a senior/subordinate shifting interest structure. Subordination is expected to be [8.8525]% +/- 0.50% with respect to the Senior Certificates.

Advances:	The Master Servicer will make cash advances with respect to delinquent payments of principal and interest on the mortgage loans to the extent the Master Servicer believes that the cash advances can be repaid from future payments on the mortgage loans.

Class I-A-1 Cap Contract:			The Class I-A-1 Certificates will have the benefit of an interest rate cap contract.

Negative Amortization:		Since the Mmortgage Lloans are subject to negative amortization, the Senior Certificates, the Mezzanine Certificates and the Subordinate Certificates are subject to increases in their principal balances. However, the amount of negative amortization that occurs in each interest accrual period with respect to each Mmortgage Lloan will be offset by unscheduled principal collections for such period. Any negative amortization that is not offset by unscheduled principal collections will be accreted pro rata to the Senior Certificates and the Subordinate Certificates based on the amount of interest due but not paid with regard to each such class without giving effect to the allocation of negative amortization.

Class I-XX Certificates:		Solely for purposes of determining distributions of principal and interest and the allocation of realized losses on the mortgage loans, the Class I-XX Certificates will be comprised of two components: an interest-only component with the notional balance described above and a principal and interest component (the "Class I-XXP Component") with a principal balance (initially, zero) that will increase depending on the amount of deferred interest allocated to the Class X Certificates.
