Notional Classes:  The Notional Classes will not receive distributions of principal but have Class Notional Balances for convenience in describing their entitlements to interest. The Class Notional Balance of each Notional Class represents the percentage indicated below of, and reduces to that extent with, the Class Principal Balance indicated: Class Original Class Notional Balance Represents Approximately IO........................................................ $ 3,255,384   3.255384%  of FA (PT Class) MI........................................................ 2,045,454   2.727272%  of MB (SEQ Class) SA ........................................................ 100,000,000 100%  of FA (PT Class) SB ........................................................ 50,000,000 100%  of FB (PT Class) SH........................................................ 40,868,571 100%  of FM (PAC I Class) SI  ........................................................ 40,868,571 100%  of FM (PAC I Class) TI ........................................................ 40,868,571 100%  of FM (PAC I Class) Tax Status:  Double REMIC Series.
