(2)  The initial Interest Rate will be in effect during the first Accrual Period; the Interest Rate will adjust monthly thereafter. The Weighted Average Coupon Classes, Classes IW and IX, will accrue interest during each Accrual  Period  in  an  amount  derived  by  aggregating  the  accrued  interest  on  their  related REMIC Classes for such Accrual Period. The initial Interest Rate of Class IW is approximately 5.33428% and of Class IX is approximately 5.58266%, each of which will be in effect for the first Accrual Period. Allocation  of  Principal:  On  each  Distribution  Date  for  a  Security  Group,  the  following distributions will be made to the related Securities: SECURITY GROUP 1 The Group 1 Principal Distribution Amount and the ZA Accrual Amount will be allocated in the following order of priority: 1.  Concurrently, to EA and FA, pro rata, until reduced to their Aggregate Scheduled Principal Balance for that Distribution Date 2.  To ZA, until retired 3.  Concurrently, to EA and FA, pro rata, without regard to their Aggregate Scheduled Principal Balances, until retired S-6
