On each Distribution Date on which the Senior Certificates (other than the Class A-P Certificates) of two or more Certificate Groups remain outstanding, any amounts distributable pursuant to this Section 3.01(b) shall be distributed in proportion to the aggregate Certificate Principal Balances of such Certificates of each such Certificate Group.

On any Distribution Date on which any Certificate Group constitutes an Undercollateralized Group, all amounts with respect to the related Mortgage Loans otherwise distributable as principal on the Subordinate Certificates, in reverse order of priority (other than amounts necessary to pay Deferred Principal Amounts or unpaid Current Shortfalls) (or, following the Credit Support Depletion Date, such other amounts described in the immediately following sentence), shall be distributed as principal to the Senior Certificates (other than any Interest Only Certificates and the Class A-P Certificates) of such Undercollateralized Group pursuant to Section 3.01(a)(2), until the aggregate Certificate Principal Balance of such Senior Certificates equals the Non-AP Pool Balance of the related Collateral Group (such distribution, an “Undercollateralization Distribution”). In the event that any Certificate Group constitutes an Undercollateralized Group on any Distribution Date following the Credit Support Depletion Date, Undercollateralization Distributions shall be made from any Available Distribution Amount for the Collateralized Groups not related to an Undercollateralized Group remaining after all required amounts have been distributed to the Senior Certificates (other than the Class A-P Certificates) of such other Certificate Groups. In addition, the amount of any unpaid Current Shortfalls with respect to an Undercollateralized Group on any Distribution Date (including any Current Shortfalls for such Distribution Date) shall be distributed to the Senior Certificates (other than the Class A-P Certificates) of such Undercollateralized Group prior to the payment of any Undercollateralization Distributions from amounts otherwise distributable as principal on the related Subordinate Certificates, in reverse order of priority (or, following the Credit Support Depletion Date, as provided in the preceding sentence).

If on any Distribution Date two or more Certificate Groups are Undercollateralized Groups, the distribution described in the immediately preceding paragraph shall be made in proportion to the amount by which the aggregate Certificate Principal Balance of the Senior Certificates (other than the Class A-P Certificates) of each such Certificate Group, after giving effect to distributions pursuant to Section 3.01(a) on such Distribution Date, exceeds the Non-AP Pool Balance of the related Collateral Group for such Distribution Date.

(c)

REMIC I-1 Distributions. On each Distribution Date, the Securities Administrator shall apply amounts in the REMIC I-1 Distribution Account to the REMIC I-1 Regular Interests in the same manner that amounts are distributed on any Corresponding Classes of Certificates on such Distribution Date.

On each Distribution Date, the Securities Administrator shall apply remaining amounts in the REMIC I-1 Distribution Account in respect of interest to the Class I Pool, Class I-Sub-A and Class I-Sub-B Interests in accordance with their interest rates set forth above. In addition, on each Distribution Date, the Trustee shall apply amounts in the REMIC I-1 Distribution Account in respect of principal to the Class I-Pool, Class I-Sub-A and Class I-Sub-B Interests as follows:

(i)

first, to the Class I-Sub-A and Class I-Sub-B Interests, the minimum amounts to each such that following that allocation the weighted average rate of the Class I-Sub-A and Class I-Sub-B Interests, weighted on the principal balances thereof and determined by subjecting the Class I-Sub-A Interest to a floor of 7.5194% and subjecting the Class I-Sub-B Interest to a cap of 4.0000%, equals the interest rate on the Class B Certificates for the following Distribution Date;

(ii)

second, to the Class I-Pool Interest until its principal balance is reduced to zero; and

(iii)

third, pro rata to the Class I-Sub-A and Class I-Sub-B Interests in accordance with their principal balances following clause (i) above.

Realized Losses and Shortfalls shall be allocated in the same manner.

The Securities Administrator shall withdraw all amounts allocated to the various REMIC I-1 Regular Interests and deposit such amounts in the Certificate Account for distribution pursuant to Section 3.01(a) above on such Distribution Date. Any amount remaining in the REMIC I-1 Distribution Account after making all other payments required under this Section 3.01(c) shall be distributed to the holder of the Class R2 Certificates.

(d)

REMIC I-2 Distributions. On each Distribution Date, the Securities Administrator shall apply amounts in the REMIC I-2 Distribution Account to the REMIC I-2 Regular Interests in the same manner that amounts are distributed on the Corresponding Classes of Certificates on such Distribution Date. Realized Losses and Shortfalls shall be allocated in the same manner. The Securities Administrator shall withdraw all amounts allocated to the various REMIC I-2 Regular Interests and deposit such amounts in the Certificate Account for distribution pursuant to Section 3.01(a) above on such Distribution Date. Any amount remaining in the REMIC I-2 Distribution Account after making all other payments required under this Section 3.01(d) shall be distributed to the holder of the Class R1 Certificates.

(e)

On each Distribution Date on which any Fair Market Value Excess is on deposit in the Certificate Account and such Fair Market Value Excess has not been previously distributed in accordance with this Section 3.01(e), the Securities Administrator shall withdraw such Fair Market Value Excess, from the Certificate Account, and shall distribute it to the Holder of the Class R2 Certificates.

Section 3.02

Allocation of Realized Losses and Shortfalls.

(a)

Realized Losses of Principal.

(i)

On each Distribution Date, the respective Applicable Fractions of each Realized Loss on a Mortgage Loan, to the extent allocable to principal, shall be allocated to the related Collateral Groups for further allocation to the Class or Classes of REMIC Interests supported by such Collateral Groups in reduction of the Certificate Balance thereof; provided, however, that any Realized Loss allocated to a Collateral Group shall be allocated first to the Subordinate Interests related to such Collateral Group, in reverse numerical order, until the Certificate Balance thereof is reduced to zero, and then pro rata to the Senior Interests related to such Collateral Group; provided further, that any Realized Loss otherwise allocable to the Class 1A-6 Certificates shall instead be allocated to the Class 1A-7 Certificates, until the Class Principal Balance thereof is reduced to zero; any Realized Loss otherwise allocable to the Class 3A-2 Certificates shall instead be allocated to the Class 3A-10 Certificates, until the Class Principal Balance thereof is reduced to zero; any Realized Loss otherwise allocable to the Class 3A-6 Certificates shall instead be allocated to the Class 3A-8 Certificates, until the Class Principal Balance thereof is reduced to zero; and any Realized Loss otherwise allocable to the Class 3A-19 Certificates shall instead be allocated to the Class 3A-20 Certificates, until the Class Principal Balance thereof is reduced to zero. Any Realized Losses allocated to a Class of REMIC Interests and not reimbursed on the same Distribution Date shall be allocated to the Corresponding Class or Classes of Certificates as described below.

(ii)

Prior to the Credit Support Depletion Date, to the extent that the principal portion of a Realized Loss has been allocated to reduce the Certificate Principal Balance of the Class A-P Interest, the amount of such Realized Loss shall be reimbursed from the Subordinate Principal Distribution Amount, to reimburse the Current Realized Losses and Deferred Principal Amounts. The distribution of any Current Realized Losses and Deferred Principal Amounts to a Class of Senior Interests on any Distribution Date shall not result in a further reduction of the Certificate Balance of such Class of Senior Interests, but instead shall result in the reduction of the Certificate Balance of the Subordinate Interests in REMIC I-2, until the Certificate Balance thereof has been reduced to zero. The Current Realized Losses and Deferred Principal Amounts shall be paid from the amounts otherwise payable to the Classes of Subordinate Interests related to the applicable REMIC, beginning with the Class having the highest numerical designation. Any Current Realized Losses and Deferred Principal Amounts not paid on the Distribution Date relating to the Due Period in which the Realized Loss was incurred shall be carried forward and shall be included in the Current Realized Losses and Deferred Principal Amounts for the next Distribution Date.

(iii)

Any Realized Losses allocated to a Class of REMIC I-2 Interests pursuant to Section 3.02(a)(i) and not reimbursed on the same Distribution Date shall be allocated on the same date to the Corresponding Class or Classes of REMIC I-3 Certificates.

(b)

Realized Losses Allocable to Interest. On each Distribution Date, the portion of each Realized Loss on a Mortgage Loan that exceeds the outstanding principal amount of such Mortgage Loan shall be allocated pro rata to the related Collateral Group or Groups, on the basis of the amount of interest due to such Collateral Group from such Mortgage Loan. On each Distribution Date, the interest portion of each Realized Loss allocated to a Collateral Group in accordance with the preceding sentence shall be further allocated pro rata, on the basis of Accrued Certificate Interest, to each Class of related REMIC Interests; provided that the interest portion of any Realized Losses allocated to the Subordinate Interests in a REMIC as provided in this Section 3.02(b) shall be allocated to such Subordinate Interests in reverse order of seniority.

(c)

Interest Shortfall. Notwithstanding anything in the Standard Terms to the contrary, on each Distribution Date, before any distributions are made on the REMIC Interests and the Certificates, Month End Interest Shortfall not covered by compensating interest from P&I Advances and Servicemembers Shortfall with respect to any Mortgage Loan shall be allocated pro rata among the Classes of the related REMIC based on the amount of interest otherwise owing thereto in reduction of that amount. Such amounts shall be allocated proportionately based on (1) in the case of the Senior Certificates, the Accrued Certificate Interest otherwise distributable thereon and (2) in the case of the Subordinate Certificates, interest accrued on their related Apportioned Principal Balances without regard to any reduction pursuant to this paragraph, for that Distribution Date.

(d)

Modification Losses. In the event that the Note Rate on a Mortgage Loan is reduced as a result of a modification of the terms of such Mortgage Loan, such modification shall be disregarded for purposes of calculating the Certificate Rate on any Class of Certificates or Class of REMIC Interest. Any shortfall resulting from any such modifications, however, shall be treated as a Realized Loss occurring on each Distribution Date and shall be applied to reduce the Certificate Balances of the Certificates and REMIC Interests in the manner and order of priority set forth above.

(e)

In the event that there is a recovery of an amount in respect of principal of a Mortgage Loan, which amount had previously been allocated as a Realized Loss to one or more Classes of Certificates (i) such amount shall be treated as a Principal Prepayment Amount and shall be included in the Available Distribution Amount for the Distribution Date occurring in the month following the month in which such recovery is received and (ii) the Certificate Balance of the Classes to which any Realized Loss had previously been allocated, whether or not such Classes remain outstanding, shall be increased in direct order of priority, in each case by an amount equal to the lesser of (x) the amount of such recovery and (y) the aggregate amount of Realized Losses previously allocated to such Classes less amounts previously allocated to such Classes pursuant to this paragraph.

Section 3.03

The Separate Interest Trust. (a) The Trustee is hereby directed by the Depositor to accept the Interest Rate Cap Agreements on behalf of a trust, separate from the Trust Estate, for the benefit of the Class 3A-1, Class 3A-2, Class 4A-1 and Class X Certificateholders (referred to herein as a “Separate Interest Trust”) in the forms presented to it by the Depositor and shall have no responsibility for the contents, adequacy or sufficiency of the Interest Rate Cap Agreements including without limitation, the representations and warranties contained therein.
