Allocation of Amount to be Distributed on the Class A Non-PO Certificates

      On each Distribution Date occurring prior to the Subordination Depletion
Date, the Class A Non-PO Principal Distribution Amount will be allocated among
and distributed in reduction of the Principal Balances of the Class A Non-PO
Certificates, sequentially, as follows:

      first, to the Class A-R Certificates;

      second, to the Class A-3 Certificates, up to the Priority Amount for such
Distribution Date;

      third, to the Class A-1 Certificates;

      fourth, concurrently, to the Class A-2 and Class A-4 Certificates, pro
rata; and

      fifth, to the Class A-3 Certificates.

      The "Priority Amount" for any Distribution Date means the product of (i)
the Priority Percentage, (ii) the Shift Percentage and (iii) the sum of the
Scheduled Principal Amount and Unscheduled Principal Amount.

      The "Priority Percentage" means the Principal Balance of the Class A-3
Certificates divided by the Aggregate Non-PO Principal Balance.

      The "Scheduled Principal Amount" means the sum for each outstanding
Mortgage Loan (including each defaulted Mortgage Loan with respect to which the
related Mortgaged Property has been acquired by the Trust Estate) of the product
of (A) the Non-PO Fraction for such Mortgage Loan and (B) the sum of the amounts
for such Mortgage Loan described in clauses B(i) and B(iv) of the definition of
"Class A Non-PO Optimal Principal Amount", but without such amounts being
multiplied by the Class A Percentage.

      The "Unscheduled Principal Amount" means the sum for each outstanding
Mortgage Loan (including each defaulted Mortgage Loan with respect to which the
related Mortgage Property has been acquired by the Trust Estate) of the product
of (A) the Non-PO Fraction for such Mortgage Loan and (B) the sum of the amounts
for such Mortgage Loan described in clauses B(ii) and B(iii) of the definition
of "Class A Non-PO Optimal Principal Amount", but without such amounts being
multiplied by the Class A Prepayment Percentage.

      The "Shift Percentage" for any Distribution Date will be the percentage
indicated below:
