     (a)  On each Distribution Date, the Trustee shall make the following
allocations from the Distribution Account of an amount equal to the Group I
Interest Funds in the following order of priority, and each such allocation
shall be made only after all preceding allocations have been made until such
amount shall have been fully allocated for such Distribution Date:

          (i)    to the Group I Class A Certificates, the Current Interest and
                 any Interest Carry Forward Amount for the Group I Class A
                 Certificates; provided, however, if the Group I Interest Funds
                 and any amounts transferred from the Capitalized Interest
                 Account for the Group I Mortgage Loans are not sufficient to
                 make a full distribution of the Current Interest and any
                 Interest Carry Forward Amount with respect to all the Group I
                 Class A Certificates, such amount will be distributed pro rata
                 among each Class of the Group I Class A Certificates based on
                 the ratio of (x) the Current Interest and Interest Carry
                 Forward Amount for each Class of the Group I Class A
                 Certificates to (y) the total amount of Current Interest and

                 Group I Interest Funds and any amounts transferred from the
                 Capitalized Interest Account for the Group I Mortgage Loans are
                 not sufficient to make a full distribution of the Current
                 Interest with respect to the Class BF-1 and Class BF-1A
                 Certificates, such Interest Funds and amounts will be
                 distributed pro rata among each Class of the Class BF-1 and
                 Class BF-1A Certificates based on the ratio of (x) the Current
                 Interest for such Class to (y) the total amount of Current
                 Interest for the Class BF-1 and Class BF-1A Certificates; and

          (v)    any remainder pursuant to Section 3.02(e) hereof.

     (b)  On each Distribution Date, the Trustee shall make the following

shall be made only after all preceding allocations shall have been made until
such amount shall have been fully allocated for such Distribution Date:

          (i)    to the Group II Class A Certificates, the Current Interest and
                 any Interest Carry Forward Amount for the Group II Class A
                 Certificates; provided, however, if the Group II Interest Funds
                 and any amounts transferred from the Capitalized Interest
                 Account for the Group II Mortgage Loans are not sufficient to
                 make a full distribution of the Current Interest and any
                 Interest Carry Forward Amount with respect to all the Group II
                 Class A Certificates, such amount will be distributed pro rata
                 among each Class of the Group II Class A Certificates based on
                 the ratio of (x) the Current Interest and Interest Carry
                 Forward Amount for each Class of the Group II Class A
                 Certificates to (y) the total amount of Current Interest and

          (iv)   pro rata, to the Class BV-1 and Class BV-1A Certificates, the
                 Class BV-1 and Class BV-1A Current Interest; provided, however,
                 if the Group II Interest Funds and any amounts transferred from
                 the Capitalized Interest Account for the Group II Mortgage
                 Loans are not sufficient to make a full distribution of the
                 Current Interest with respect to the Class BV-1 and Class BV-1A
                 Certificates, such Interest Funds and amounts will be
                 distributed pro rata among each Class of the Class BV-1 and
                 Class BV-1A Certificates based on the ratio of (x) the Current
                 Interest for such Class to (y) the total amount of Current
                 Interest for the Class BV-1 and Class BV-1A Certificates; and

                 Class AF-2, Class AF-3, Class AF-4, Class AF-5 and Class AF-6
                 Certificates so that no such distribution pursuant to this
                 clause (y) will be made to any such Class until the Certificate
                 Principal Balances of all Group I Class A Certificates with a
                 lower numeral designation shall have been reduced to zero;
                 provided, however, that, on any Distribution Date on which the
                 Group I Class A Certificate Principal Balance is equal to or
                 greater than the Scheduled Principal Balances of Group I, the
