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 related 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 related 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 related 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)

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 1A-2 Certificates shall instead be allocated to the Class 1A-17 Certificates, until the Class Principal Balance of the Class 1A-17 Certificates is reduced to zero; (b) Realized Losses otherwise allocable to the Class 1A-9 Certificates shall instead be allocated to the Class 1A-10 Certificates, until the Class Principal Balance of the Class 1A-10 Certificates has been reduced to zero; (c) Realized Losses otherwise allocable to the Class 1A-15 Certificates shall instead be allocated to the Class 1A-16 Certificates, until the Class Principal Balance of the Class 1A-16 Certificates has been reduced to zero; (d) Realized Losses otherwise allocable to the Class 2A-5 Certificates shall instead be allocated to the Class 2A-6 Certificates, until the Class Principal Balance of the Class 2A-6 Certificates has been reduced to zero; (e) Realized Losses otherwise allocable to the Class 2A-7 Certificates shall instead be allocated to the Class 2A-11 Certificates until the Class Principal Balance of the Class 2A-11 Certificates has been reduced to zero; (f) Realized Losses otherwise allocable to the Class 2A-9 Certificates shall instead be allocated to the Class 2A-10 Certificates, until the Class Principal Balance of the Class 2A-10 Certificates has been reduced to zero; (g) Realized Losses otherwise allocable to the Class 2A-16 Certificates shall instead be allocated to the Class 2A-17 Certificates, until the Class Principal Balance of the Class 2A-17 Certificates has been reduced to zero; (h) Realized Losses otherwise allocable to the Class 4A-1 Certificates (or any Class of certificates in the 4A-1 Group) shall instead be allocated to the Class 4A-2 Certificates until the Class Principal Balance of the Class 4A-2 Certificates has been reduced to zero; (i) Realized Losses otherwise allocable to the Class 5A-8 Certificates (or any Class of certificates in the 5A-8 Group), the Class 5A-1 Certificates or the Class 5A-9 Certificates shall instead be allocated to the Class 5A-2 Certificates, until the Class Principal Balance of the Class 5A-2 Certificates has been reduced to zero and, after the Class Principal Balance of the Class 5A-2 Certificates has been reduced to zero, Realized Losses otherwise allocable to the Class 5A-1 Certificates shall instead be allocated to the Class 5A-9 Certificates, until the Class Principal Balance of the Class 5A-9 Certificates has been reduced to zero; and (j) 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)

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 related Class A-P Interest, the amount of such Realized Loss shall be reimbursed from the aggregate Subordinate Principal Distribution Amount for the related Collateral Groups, 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 MT, 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 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.

Section 3.03.

The Separate Interest Trust.

The Depositor hereby assigns and conveys to the Securities Administrator on behalf of the Trustee, and the Securities Administrator on behalf of the Trustee is hereby directed by the Depositor to accept and does accept, the Interest Rate Cap Agreement on behalf of a trust, separate from the Trust Estate, for the benefit of the Class 2A-7 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.

Section 3.04.

Basis Risk Reserve Fund.

(a)

On the Closing Date, the Securities Administrator shall establish and maintain in the name of the Trustee, in the Separate Interest Trust for the benefit of the holders of the Class 2A-7 and Class X Certificates, the Basis Risk Reserve Fund, into which the Depositor shall deposit $1,000. The Securities Administrator on behalf of the Trustee shall hold the Interest Rate Cap Agreement as an asset in the Basis Risk Reserve Fund. The Basis Risk Reserve Fund shall be an Eligible Account, and funds on deposit therein shall be held separate and apart from, and shall not be commingled with, any other moneys, including without limitation other moneys of the Securities Administrator held pursuant to this Agreement. The Basis Risk Reserve Fund shall not be an asset of any REMIC or the Trust Estate established hereby.

(b)

On each Distribution Date, after deposit of any portion of Interest Rate Cap Amounts remaining after distributions to the Holders of the Class 2A-7 Certificates pursuant to Section 3.05(c), the Securities Administrator shall distribute the amounts then on deposit in the Basis Risk Reserve Fund, including any earnings thereon, on behalf of the Trust Estate for distribution to the Class 2A-7 Certificates in the amount of (i) any remaining Basis Risk Shortfalls for such Class and such Distribution Date and (ii) any Basis Risk Shortfalls for such Class that remain unpaid from prior Distribution Dates. On any Distribution Date, any amounts that the Securities Administrator is not required to distribute from the Basis Risk Reserve Fund pursuant to this Section 3.04(b) shall remain on deposit in the Basis Risk Reserve Fund.

(c)

Funds in the Basis Risk Reserve Fund shall be invested in the ▇▇▇▇▇ Fargo Prime Advantage Money Market Fund. Any earnings on amounts in the Basis Risk Reserve Fund shall be for the benefit of the Class X Certificateholder. The Class X Certificate shall evidence ownership of the Basis Risk Reserve Fund for federal income tax purposes and the Class X Certificateholder shall direct the Trustee, in writing, as to investment of amounts on deposit therein. The Class X Certificateholder shall be liable for any losses incurred on such investments. In the absence of written instructions from the Class X Certificateholder as to investment of funds on deposit in the Basis Risk Reserve Fund, such funds shall be invested in money market funds as described in clause (v) of the definition of Permitted Investments.

(d)

Upon the earlier to occur of (i) the Distribution Date on which the Class Principal Balance of each of the Class 2A-7 Certificates is reduced to zero and (ii) the termination of the Trust Estate, any amounts remaining in the Basis Risk Reserve Fund shall be distributed to the Class X Certificateholder.

(e)

For federal income tax purposes, the Securities Administrator shall treat the holders of the Class 2A-7 Certificates as having entered into a notional principal contract with the holders of the Class X Certificates. Pursuant to such notional principal contract, all holders of the Class X Certificates shall be treated as having agreed to pay Basis Risk Shortfalls to the holders of the Class 2A-7 Certificates. Any payments to the Class 2A-7 Certificates in light of the foregoing shall not be payments with respect to a “regular interest” in a REMIC within the meaning of Code Section 860G(a)(1). Notwithstanding the priority and sources of payments set forth in Article III hereof or otherwise, the Securities Administrator shall account for all distributions on the Certificates as set forth in this section. For purposes of providing tax information reporting with respect to the Class 2A-7 Certificates, the Securities Administrator shall treat the notional principal contract described in this paragraph as having a value of $10,000.00 as of the Closing Date.

Section 3.05.

Any Interest Rate Cap Amounts received by the Securities Administrator on behalf of the Trustee pursuant to the Interest Rate Cap Agreement in connection with each such Distribution Date shall be deposited by the Securities Administrator on behalf of the Trustee into the Basis Risk Reserve Fund.

(c)

On each Distribution Date, the Securities Administrator on behalf of the Separate Interest Trust shall distribute amounts on deposit in the Basis Risk Reserve Fund representing the Interest Rate Cap Amount for such Distribution Date first, to the Holders of the Class 2A-7 Certificates, in an amount equal to the product of (i) one-twelfth and (ii) the excess, if any, of LIBOR for such Distribution Date (up to a maximum of 9.48% per annum) over 5.48% and (iii) the lesser of (x) an amount equal to the applicable notional amount under the Interest Rate Cap Agreement for such Distribution Date and (y) the aggregate Certificate Principal Balance of the Class 2A-7 Certificates for such Distribution Date and second, to the Holders of the Class 2A-7 Certificates, in an amount up to any Basis Risk Shortfalls on the Class 2A-7 Certificates remaining unpaid from prior Distribution Dates. Any portion of the Interest Rate Cap Amount remaining after such distributions shall be retained in the Basis Risk Reserve Fund for distribution pursuant to Section 3.04.

(d)

Upon termination of the Interest Rate Cap Agreement and payment of all amounts owed by the Interest Rate Cap Counterparty thereunder, following application by the Securities Administrator on behalf of the Trustee of funds in the Basis Risk Reserve Fund on the next succeeding Distribution Date to pay amounts owed pursuant to this Section and Section 3.04, the Securities Administrator on behalf of the Trustee shall terminate the Basis Risk Reserve Fund.

(e)

In the event of an early termination of the Interest Rate Cap Agreement, any termination payment made by the Interest Rate Cap Counterparty to the Separate Interest Trust (“Termination Receipts”) shall be deposited in a segregated non-interest bearing account which shall be an Eligible Account established by the Securities Administrator on behalf of the Trustee of the Separate Interest Trust (the “Termination Receipts Account”).

All income and gain realized from any such investment shall be deposited in the Termination Receipts Account.

(f)

Unless otherwise permitted by the Rating Agencies, the Securities Administrator shall promptly, with the assistance and cooperation of the Depositor, use amounts on deposit in the Termination Receipts Account, if necessary, to enter into replacement Interest Rate Cap Agreements which shall be executed and delivered by the Trustee of the Separate Interest Trust upon receipt of written confirmation from each Rating Agency that such replacement Interest Rate Cap Agreement(s) shall not result in the reduction or withdrawal of the rating of the Class 2A-7 Certificates.
