(c)

REMIC LT1 Distributions. On each Distribution Date, the Securities Administrator shall apply amounts in the REMIC LT1 Distribution Account to the REMIC LT1 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 LT1 Distribution Account in respect of interest to the Class LT1 Pool, Class LT1-Sub-A and Class LT1-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 LT1 Distribution Account in respect of principal to the Class LT1-Pool, Class LT1-Sub-A and Class LT1-Sub-B Interests as follows:

(i)

first, to the Class LT1-Sub-A and Class LT1-Sub-B Interests, the minimum amounts to each such that following that allocation the weighted average rate of the Class LT1-Sub-A and Class LT1-Sub-B Interests, weighted on the principal balances thereof and determined by subjecting the Class LT1-Sub-A Interest to a floor of 7.7762% and subjecting the Class LT1-Sub-B Interest to a cap of 4.0000%, equals the interest rate on the Class 1-B Certificates for the following Distribution Date;

(ii)

second, to the Class LT1-Pool Interest until its principal balance is reduced to zero; and

(iii)

third, pro rata to the Class LT1-Sub-A and Class LT1-Sub-B Interests in accordance with their principal balances following clause (i) above.

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

Realized Losses and Shortfalls shall be allocated in the same manner. The Securities Administrator shall withdraw all amounts allocated to the various REMIC MT 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 MT Distribution Account after making all other payments required under this Section 3.01(d) shall be distributed to the holder of the Class R 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 RC 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 (a) Realized Losses otherwise allocable to the Class 2A-13 Certificates shall instead be allocated to the Class 2A-14 Certificates, until the Class Principal Balance of the Class 2A-14 Certificates is reduced to zero; (b) Realized Losses otherwise allocable to the Class 3A-4 Certificates shall instead be allocated to the Class 3A-5 Certificates, until the Class Principal Balance of the Class 3A-5 Certificates has been reduced to zero; and (c) any Realized Loss 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)

Any Realized Losses allocated to a Class of REMIC MT 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 UT 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, on the Class Principal Balance thereof, in the case of the Senior Certificates, and the related Apportioned Principal Balance, in the case of the Subordinated Interests, to each Class of related REMIC Interests; provided that the interest portion of any Realized Losses allocated to the related 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 Monthly 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 of any Subsequent Recovery, (i) such amount shall be treated as a Principal Prepayment Amount and shall be included in the related 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 Class or Classes to which the related Realized Loss had previously been allocated, whether or not such Class or Classes 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.
