                will supply AAIPharma with sufficient quantities of Active Pharmaceutical
                Ingredient (“API”) and a current MSDS. Note:
                Client will supply the API accompanied by a Certificate of Analysis
                (COA)
                and a release statement or a COA from an independent laboratory in
                order
                for AAIPharma to perform limited release testing.

      performed on the drug product. Data reports will be provided as generated for
      each time point and a final report will be issued at the end of the study.
      A
      stability protocol will be developed by AAIPharma and reviewed and accepted
      in
      writing by Protalex. The stability protocol and analytical testing are described
      in the following table:

    In
      addition, Client will be charged for all out-of-pocket costs and/or expenses
      associated with the activities outlined herein. Such costs and expenses shall
      include required raw materials, travel and shipping expenses, and lab supplies
      such as columns, standards and chemicals unavailable from Client. All documented
      and reasonable out-of-pocket costs and/or expenses will be billed at cost plus
      15%. Actual costs based on vendor invoices plus 15% will be
      invoiced.

    

    AAIPharma
      will provide Client with copies of raw data upon request. These data will be
      provided at a charge of $XXXX for non-chromatographic projects and $XXXX for
      chromatographic projects. 

    

    AAIPharma
      will revise the final reports once at no additional charge upon Client’s
      request. Additional revisions to final reports will be conducted at $XXXX per
      hour. Client will not be charged for revisions required due to AAIPharma
      error.

    

    AAIPharma
      will notify Client should testing yield aberrant or out-of-specification data.
      All work (including time spent reviewing the investigation with laboratory
      management and quality assurance personnel) associated with laboratory
      investigations that are not due to AAIPharma’s error will be charged to Client
      at $XXXX per hour. Client also agrees to pay for any re-tests that confirm
      the
      original test results including marginal pass/fail results.

    

    AAIPharma
      will perform all testing per the methods indicated. Should method optimization
      or development be required, Client will be notified and, upon approval, method
      optimization/development will be conducted at $XXXX per hour.

    

    Stability
      setup and storage charges are due and payable upon initiation of the study.
      These fees are not refundable. Client will be entitled to terminate the project
      at any time with thirty (30) days prior written notice. Any revisions to the
      stability protocol made after the initiation of the study will be charged to
      Client at $XXXX per hour. 

    

    This
      cost
      estimate is based on the information available and AAIPharma’s experience with
      the procedures involved. AAIPharma reserves the right to revise this Agreement
      should the scope of the project change. Any changes in the scope or the nature
      of the work covered by this service Agreement must be mutually agreed to and
      confirmed by a written change order.

    PRELIMINARY
      STATEMENT

     

    The
      Board
      of Directors of the Depositor has duly authorized the formation of GSR Mortgage
      Loan Trust 2007-2F as a trust (the “Trust”)
      to
      issue a series of securities with an aggregate initial outstanding principal
      balance of $627,203,524 to be known as the Mortgage Pass-Through Certificates,
      Series 2007-2F (the “Certificates”).
      The
      Trust is formed by this Trust Agreement. The Certificates in the aggregate
      evidence the entire beneficial ownership in the Trust. The Certificates consist
      of the Classes set forth herein. 

     

    Pursuant
      to Section 12.01 of the Standard Terms, the Securities Administrator, on behalf
      of the Trustee, shall make an election to treat all of the Trust Estate as
      three
      real estate mortgage investment conduits (each, a “REMIC”
and,
      individually, “REMIC
      LT1,”
      “REMIC
      MT”
and
      “REMIC
      UT”)
      for
      federal income tax purposes. 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 number
      of
      the Senior Certificates (“1,” “2,” “3” or “4”), if any, refers to the Collateral
      Group, the letter (“A,” “M” or “B”), refers to the status of the interest (“A”
for senior or “M” or “B” for subordinate) and the final character or characters
      (“1,” “2,” “3,” “4,” “5,” “6,” “7,” “8,” “9,” “10,” “P,” “R” or “RC”) refers to
      the specific Class.

     

    NOW,
      THEREFORE, in consideration of the mutual promises, covenants, representations
      and warranties hereinafter set forth, the Depositor, the Trustee, the Securities
      Administrator, the Custodians and the Master Servicer agree as

      2.01. Conveyance
      to the Trustee.

     

    (a) To
      provide for the distribution of the principal of and interest on the
      Certificates and Interests in accordance with their terms, all of the sums
      distributable under this Trust Agreement with respect to the Certificates and
      the Interests and the performance of the covenants contained in this Trust
      Agreement, the Depositor hereby bargains, sells, conveys, assigns and transfers
      to the Trustee, in trust, without recourse and for the exclusive benefit of
      the
      Holders of the Certificates, all of the Depositor’s right, title and interest in
      and to any and all benefits accruing to the Depositor from: (i) the Mortgage
      Loans, the related Trustee Mortgage Loan Files, and all Monthly Payments due
      thereon after the Cut-Off Date and all principal prepayments collected with
      respect to the Mortgage Loans and paid by a Borrower on or after the Cut-Off
      Date, and proceeds of the conversion, voluntary or involuntary, of the
      foregoing; (ii) the Sale and Servicing Agreements; provided
      that the
      Depositor hereby reserves its right to indemnification under the Sale and
      Servicing Agreements; (iii) the Custodial Agreement; (iv) the Assignment
      Agreements; (v) the Distribution Account, the Master Servicer Account, the
      Certificate Account and the Collection Accounts and (vi) proceeds of all of
      the
      foregoing (including, without limitation, all amounts, other than investment
      earnings, from time to time held or invested in the Collection Account and
      the
      Certificate Account, whether in the form of cash, instruments, securities or
      other property, all proceeds of any mortgage insurance, mortgage guarantees,
      hazard insurance, or title insurance policy relating to the Mortgage Loans,

      or
      part or are included in the proceeds of any of the foregoing) to pay the REMIC
      Interests and the Certificates as specified herein (collectively items (i)
      through (vi), the “Trust Estate”). 

     

    (b) It
      is
      intended that the conveyance of the Trust Estate by the Depositor to the Trustee
      as provided in this Section be, and be construed as, a sale of the Trust Estate
      by the Depositor to the Trustee for the benefit of the Certificateholders.
      It
      is, further, not intended that such conveyance be deemed a pledge of the Trust
      Estate by the Depositor to the Trustee to secure a debt or other obligation
      of
      the Depositor. However, in the event that the Trust Estate is held to be the
      property of the Depositor, or if for any reason this Agreement is held or deemed
      to create a security interest in the Trust Estate, then it is intended that
      this
      Agreement shall also be deemed to be a security agreement within the meaning
      of
      Articles 8 and 9 of the UCC and the corresponding articles of the Uniform
      Commercial Code of any other applicable jurisdiction; and the Depositor hereby
      grants to the Trustee for the benefit of the Certificateholders a security
      interest in all of the Depositor’s right, title and interest, whether now owned
      or existing or hereafter acquired or arising, in and to the Trust Estate. The
      Depositor and the Trustee, at the Depositor’s direction and expense, shall, to
      the extent consistent with this Agreement, take such actions as may be necessary
      to ensure that, if this Agreement were deemed to create a security interest
      in
      assets constituting the Trust Estate described above, such security interest
      would be deemed to be a perfected security interest of first priority under
      applicable law and will be maintained as such throughout the term of the
      Agreement.

    (c) The
      foregoing sale, transfer, assignment, set-over and conveyance does not and
      is
      not intended to result in the creation of an assumption by the Trustee of any
      obligation of the Depositor, the Seller or any other person in connection with
      the Mortgage Loans, the Sale and Servicing Agreements, the Assignment Agreements
      or under any agreement or instrument relating thereto except as specifically
      set
      forth herein.

     

    (d) It
      is
      agreed and understood by the Depositor and the Trustee (and the Depositor so
      represents and recognizes) that it is not intended that any Mortgage Loan to
      be
      included in the Trust Estate be (i) a “High-Cost Home Loan” as defined in the
      New Jersey Home Ownership Act effective November 27, 2003, (ii) a “High-Cost
      Home Loan” as defined in the New Mexico Home Loan Protection Act effective

      effective February 1, 2005.

     

    Section
      2.02. Acceptance
      by the Trustee and Securities Administrator.

     

    By
      its
      execution of this Trust Agreement, the Trustee acknowledges and declares that

      Custodian) all documents delivered to any such person from time to time with
      respect to the Mortgage Loans and all assets included in the definition of
      Trust
      Estate herein in trust for the exclusive use and benefit of all present and
      future Holders of the Certificates. The Trustee has not created and shall not
      create, and no Officer of the Trustee has any actual knowledge or has received
      actual notice of, any interest in the Trust Estate contrary to the interests
      created by this Trust Agreement. The Trustee has not entered, nor intends to
      enter, into any subordination agreement or intercreditor agreement with respect
      to any assets included in the Trust Estate.

      appointment of the Custodians and agrees to deliver, or cause to be delivered,
      to the applicable Custodian all Mortgage Loan documents that are to be included
      in the Trustee Mortgage Loan File for each Mortgage Loan for which such
      Custodian shall act as custodian. The Depositor and the Custodians acknowledge
      that, pursuant to the Custodial Agreement and in connection with the formation
      of the Trust, the Depositor hereby assigns the Custodial Agreement to the
      Trustee and agrees to cause a receipt to be issued in the name of the Trustee.
      It is understood that each Custodian will charge for its services under this
      Agreement as set forth in a separate agreement between such Custodian and the
      Securities Administrator, the payment of which fees and expenses (as set forth
      in such separate agreement) shall be the sole obligation of the Securities
      Administrator. The Securities Administrator will further pay or reimburse each
      Custodian upon its request for all reasonable expenses, disbursements and
      advances incurred or made by such Custodian in accordance with this Agreement,
      the Custodial Agreement and any document executed in connection herewith or
      therewith.

              (7)

            	
              to
                the Class 3A-7 and Class 3A-8 Certificates, pro
                rata,
                in proportion to the Class Principal Balance of each such class,
                until the
                Class Principal Balance of each such class is reduced to
                zero;

            

    

     

    (D) to
      the
      Class 4A-1 Certificates, in reduction of their Class Principal Balance, from
      the
      Available Distribution Amount for Collateral Group 4 in an amount up to the
      Senior Principal Distribution Amount for Collateral Group 4 for such
      Distribution Date, until the Class Principal Balance of such class is reduced
      to
      zero; and

     

    (E) to
      the
      Class A-P Certificates, in reduction of their Class Principal Balance, from
      the
      Available Distribution Amount for Collateral Group P in an amount up to the
      A-P
      Principal Distribution Amount for Collateral Group P for such Distribution
      Date,
      until the Class Principal Balance thereof is reduced to zero;

     

    (iii) from
      amounts otherwise payable to the Subordinate Certificates, to the Class A-P
      Certificates, the principal portion of Current Realized Losses and the Deferred
      Principal Amount for such Class A-P Certificates and such Distribution Date,
      provided,
      however,
      that, if
      necessary, the aggregate of all such amounts distributed on such Distribution
      Date shall not exceed the aggregate Subordinate Principal distribution Amount
      (without regard to the proviso of such definition) for the Subordinate
      Certificates and, provided
      further,
      that
      such amounts shall not reduce the Class Principal Balance of such Class A-P
      Certificates;

     

    (iv) 
      to the
      extent of the remaining Available Distribution Amount for Collateral Group
      1,
      Collateral Group 2, Collateral Group 3 and Collateral Group 4, but subject
      to
      the prior distribution of amounts described under Section 3.01(e) below, to
      the
      related classes of Subordinate Certificates, in their order of seniority the
      sum
      of (i) Accrued Certificate Interest pro
      rata on
      the
      basis of the amount owing to each such Class, and (ii) their pro
      rata shares,
      based on their outstanding Certificate Balances, of the Subordinate Principal
      Distribution Amount for each such Collateral Group, as applicable; provided,
      however,
      that on
      any Distribution Date on which the Subordination Level for any Class of
      Subordinate Certificates is less than its Subordination Level as of the Closing
      Date, the portion of the related Subordinate Principal Prepayment Amount
      otherwise allocable to the Class or Classes of the Subordinate Certificates
      junior to such class will be allocated pro
      rata
      to the
      most senior Class of Subordinate Certificates for which the Subordination Level
      on such Distribution Date is less than the Subordination Level as of the Closing
      Date and all Classes of Subordinate Certificates senior thereto;
      and

     

    (v) to
      each
      related Class of Certificates, in the order of their seniority, the amount
      of
      any unreimbursed Realized Losses previously allocated to such Certificates;
      and

     

    (vi) after
      all
      of the other Classes of Certificates (other than the Residual 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 (other than any Fair
      Market Value Excess remaining after an optional termination of the Trust Estate)
      to the Class RC Certificates to the extent such remainder is applicable to
      REMIC
      LT1 and otherwise to the Class R Certificates. 

     

    
      
        
        

      

      
        29

        
          

        

      

      
        
        

      

    

    (b) On
      each
      Distribution Date on or after the Credit Support Depletion Date, to the extent
      of the Available Distribution Amount allocable to each Collateral Group on
      such
      Distribution Date, distributions shall be made to the Senior Certificates
      related to each such Collateral Group, in respect of interest (pro
      rata
      according to Accrued Certificate Interest for such Distribution Date) and then
      with respect to principal (pro
      rata
      according to their outstanding principal balances; and the remainder (other
      than
      any Fair Market Value Excess remaining after the optional termination of the
      Trust Estate), if any, which is expected to be zero, of the Available
      Distribution Amount for each such Collateral Group shall be distributed to
      the
      holders of the Class RC Certificates to the extent such remainder is applicable
      to REMIC LT1 and otherwise to the holder of the Class R
      Certificates.

     

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

     

    (c) 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 related Subordinate
      Certificates, in reverse order of priority (other than amounts necessary to
      pay
      Deferred Principal Amounts or unpaid Current Shortfalls) (or, following the
      related 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(e),
      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 related Credit Support Depletion Date,
      Undercollateralization Distributions shall be made from any Available
      Distribution Amount for each related Collateral Group that does not constitute
      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 REMIC Certificates that are 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).

     

    
      
        
        

      

      
        30

        
          

        

      

      
        
        

      

    

    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 REMIC Certificates that are 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.

     

    (d) 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 7.680% and subjecting the Class
                LT1-Sub-B
                Interest to a cap of 4.000%, equals the interest rate on the Class
                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.

     

    The
      Securities Administrator shall withdraw all amounts allocated to the various
      REMIC LT1 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 LT1 Distribution Account after making all
      other payments required under this Section 3.01(d) shall be distributed to
      the
      holder of the Class RC Certificates.

     

    
      
        
        

      

      
        31

        
          

        

      

      
        
        

      

    

    (e) REMIC
      MT
      Distributions. On each Distribution Date, the Securities Administrator shall
      apply amounts in the REMIC MT Distribution Account to the REMIC MT 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 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(e) shall be distributed to the holder of the Class R
      Certificates.

     

    (f) 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(h), 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) any Realized Losses otherwise allocable to the Class 1A-4 Certificates
      shall
      instead be allocated to the Class 1A-5 Certificates, until the Class Principal
      Balance of the Class 1A-5 Certificates is reduced to zero; (b) any Realized
      Losses otherwise allocable to the Class 2A-7 Certificates shall instead be
      allocated to the Class 2A-8 Certificates, until the Class Principal Balance
      of
      the Class 2A-8 Certificates is reduced to zero; and (c) any Realized Losses
      otherwise allocable to the Class 3A-7 Certificates shall instead be allocated
      to
      the Class 3A-8 Certificates, until the Class Principal Balance of the Class
      3A-8
      Certificates is reduced to zero.

     

    (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 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.

     

    
      
        
        

      

      
        32

        
          

        

      

      
        
        

      

    

    (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.

     

    (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 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.

      or
      Interests, as applicable, that may be executed and delivered under this Trust
