The “startup day” of each REMIC for purposes of the REMIC Provisions is the Closing Date.

For purposes of naming the REMIC Interests and the Certificates, the first character (“I,” “II,” and “III”) refers to the Collateral Group; the second character (“A” or “B”) refers to the status of the interest (senior or subordinate) and the final character refers to the specific Class.

to the Senior Certificates related to such Collateral Group, other than any related Interest Only Certificates, to the extent of the remaining Available Distribution Amount for the related Collateral Group, as follows:

(A)

to the Class IA-1 and Class IA-2 Certificates, in reduction of their respective Class Principal Balances, from the Available Distribution Amount for Collateral Group I in an amount up to the Senior Principal Distribution Amount for Collateral Group I, pro rata to the Class IA-1 and Class IA-2 Certificates, until the Class Principal Balance of each such Class is reduced to zero;

(B)

(v)

to the Residual Certificates, after all of the other Classes of Certificates have been paid in full, the remainder, if any, which is expected to be zero, of the Available Distribution Amount for all Collateral Groups.

(b)

On each Distribution Date prior to the Credit Support Depletion Date but after the date on which the aggregate Certificate Principal Balance of the Senior Certificates of any Certificate Group has been reduced to zero, amounts otherwise distributable as principal on each Class of Subordinate Certificates pursuant to Section 3.01(a)(iii), in reverse order of priority, in respect of such Class’s Subordinate Class Percentage of the Subordinate Principal Distribution Amount for the Collateral Group relating to such retired Senior Certificates, shall be distributed as principal to the Senior Certificates (other than any Notional Certificates) remaining outstanding pursuant to Section 3.01(a)(ii) until the Class Principal Balances thereof have been reduced to zero, provided that on such Distribution Date (a) the related Aggregate Subordinate Percentage for such Distribution Date is less than 200% of such Aggregate Subordinate Percentage as of the Cut-Off Date or (b) the average outstanding principal balance of the Mortgage Loans contributing to any Collateral Group that are delinquent 60 days or more for the last six months (including Mortgage Loans in foreclosure or bankruptcy and property held by the Trust) as a percentage of the related Group Subordinate Amount is greater than or equal to 50%.

On each Distribution Date on which the aggregate Certificate Principal Balance of the Senior Certificates of two or more Certificate Groups has been reduced to zero, any amounts distributable pursuant to this Section 3.01(b) will be allocated, as to each applicable Class of Subordinate Certificates, in proportion to such Class’s Subordinate Class Percentage of the Subordinate Principal Distribution Amount for the Collateral Group relating to each such retired Certificate Group.

On each Distribution Date on which the Senior Certificates of two or more Certificate Groups remain outstanding, any amounts distributable pursuant to this Section 3.01(b) will 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 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), will be distributed as principal to the Senior Certificates (other than any Notional Certificates) of such Undercollateralized Group pursuant to Section 3.01(a)(ii), until the aggregate Certificate Principal Balance of such Senior Certificates equals the 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 will 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 of such other Certificate Groups.

If on any Distribution Date two or more Certificate Groups are Undercollateralized Groups, the distribution described in the immediately preceding paragraph will be made in proportion to the amount by which the aggregate Certificate Principal Balance of the Senior Certificates of each such Certificate Group, after giving effect to distributions pursuant to Section 3.01(a) on such Distribution Date, exceeds the 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 Interest and the Class I-Sub-B Interest, 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 7.250% and subjecting the Class I-Sub-B Interest to a cap of 4.940%, 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 Interest and the 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 REMIC I-2 Distribution Account for distribution pursuant to section 3.01(d) below 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 I-R 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 REMIC I-3 Distribution 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(c) shall be distributed to the holder of the Class 2-R 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 II-IA-1 Interest shall instead be allocated to the Class II-IA-2 Interest, until the Class Principal Balance thereof has been reduced to zero, and losses allocable to the Class II-IIIA-1 Interest shall instead be allocated to the Class II-IIIA-3 Interest, until the Class Principal Balance thereof has been 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)

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 seniority, 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.
