    This
      TRUST AGREEMENT, dated as of December 1, 2006 (the “Agreement”), is by and among
      STRUCTURED ASSET SECURITIES CORPORATION, a Delaware corporation, as depositor
      (the “Depositor”), AURORA LOAN SERVICES LLC, as master servicer (the “Master
      Servicer”), and U.S. BANK NATIONAL ASSOCIATION, a national banking association,
      as trustee (the “Trustee”).

     

    PRELIMINARY
      STATEMENT

     

    The
      Depositor has acquired the Mortgage Loans from Lehman Brothers Holdings Inc.
      (the “Seller”), and at the Closing Date is the owner of the Mortgage Loans and
      the other property being conveyed by it to the Trustee hereunder for inclusion
      in the Trust Fund. On the Closing Date, the Depositor will acquire the
      Certificates from the Trust Fund as consideration for its transfer to the Trust
      Fund of the Mortgage Loans and the other property constituting the Trust Fund.
      The Depositor has duly authorized the execution and delivery of this Agreement
      to provide for the conveyance to the Trustee of the Mortgage Loans and the
      other
      property constituting the Trust Fund. All covenants and agreements made by
      the
      Seller in the Mortgage Loan Sale Agreement and by the Depositor, the Master
      Servicer and the Trustee herein with respect to the Mortgage Loans and the
      other
      property constituting the Trust Fund are for the benefit of the Holders from
      time to time of the Certificates and, to the extent provided herein, any NIMS
      Insurer. The Depositor, the Trustee and the Master Servicer are entering into
      this Agreement, and the Trustee is accepting the Trust Fund created hereby,
      for
      good and valuable consideration, the receipt and sufficiency of which are hereby
      acknowledged.

     

    As
      provided herein, the Trustee shall elect that the Trust Fund (other than (i)
      the
      Basis Risk Reserve Fund, (ii) the rights to receive Prepayment Premiums
      distributable to the Class P Certificates, (iii) the Class X Account, (iv)
      the
      assets of the Grantor Trusts established pursuant to Section 5.02(h) and (v)
      the
      Lower Tier Interests) be treated for federal income tax purposes as comprising
      two real estate mortgage investment conduits (each a “REMIC” or, in the
      alternative, “REMIC 1” and “REMIC 2”). Each LIBOR Certificate represents
      ownership of a regular interest in REMIC 2 for purposes of the REMIC Provisions.
      In addition, each LIBOR Certificate represents the right to receive payments
      with respect to Excess Interest. In addition, each of the Class 1-A3B
      Certificates represents ownership of the Balance Guaranteed Cap Agreement.
      Each
      Grantor Trust Certificate represents a beneficial interest in a Grantor Trust
      holding the related Underlying Interest and certain other assets for the benefit
      of the Grantor Trust Certificates. The Class R Certificate represents ownership
      of the sole Class of residual interest in each of REMIC 1 and REMIC
      2.

     

    REMIC
      2
      shall hold as its assets the several Classes of uncertificated REMIC 1 Regular
      Interests and each such REMIC 1 Regular Interest is hereby designated as a
      regular interest in REMIC 1. REMIC
      1
      shall hold as its assets the property of the Trust Fund other than (i) the
      Lower
      Tier Interests, (ii) the Basis Risk Reserve Fund, (iii) the Class X Account,
      (iv) the assets of the Grantor Trusts established pursuant to Section 5.02(h)
      and (v) the rights to receive Prepayment Premiums distributable to the Class
      P
      Certificates.

     

    The
      startup day for each REMIC created hereby for purposes of the REMIC Provisions
      is the Closing Date. In addition, for purposes of the REMIC Provisions, the
      latest possible maturity date for each regular interest in each REMIC created
      hereby is the Latest Possible Maturity Date.

    LIBOR:
      With
      respect to the first Accrual Period, the Initial LIBOR Rate. With respect to
      each subsequent Accrual Period, a per annum rate determined on the LIBOR
      Determination Date in the following manner by the Trustee on the basis of the
      “Interest Settlement Rate” set by the British Bankers’ Association (the “BBA”)
      for one-month United States dollar deposits, as such rates appear on the
      Telerate Page 3750, as of 11:00 a.m. (London time) on such LIBOR Determination
      Date.

     

    If
      on
      such a LIBOR Determination Date, the BBA’s Interest Settlement Rate does not
      appear on the Telerate Page 3750 as of 11:00 a.m. (London time), or if the
      Telerate Page 3750 is not available on such date, the Trustee will obtain such
      rate from Reuters’ “page LIBOR 01” or Bloomberg’s page “BBAM.” If such rate is
      not published for such LIBOR Determination Date, LIBOR for such date will be
      the
      most recently published Interest Settlement Rate. In the event that the BBA
      no
      longer sets an Interest Settlement Rate, the Trustee will designate an
      alternative index that has performed, or that the Trustee expects to perform,
      in
      a manner substantially similar to the BBA’s Interest Settlement Rate. The
      Trustee will select a particular index as the alternative index only if it
      receives an Opinion of Counsel (a copy of which shall be furnished to any NIMS
      Insurer), which opinion shall be an expense reimbursed from the Certificate
      Account pursuant to Section 4.04, that the selection of such index will not
      cause any of the REMICs to lose their classification as REMICs for federal
      income tax purposes.

     

    The
      establishment of LIBOR by the Trustee and the Trustee’s subsequent calculation
      of the Certificate Interest Rate applicable to the LIBOR Certificates for the
      relevant Accrual Period, in the absence of manifest error, will be final and
      binding.

     

    LIBOR
      Business Day:
      Any day
      on which banks in London, England and The City of New York are open and
      conducting transactions in foreign currency and exchange.

      expense, an Opinion of Counsel addressed to the Trustee (which must be

      the Trustee’s interest in the related Non-MERS Mortgage Loans; provided,
      further, that notwithstanding the delivery of any Opinion of Counsel, the Master
      Servicer shall cause the Servicer to submit each Assignment of Mortgage for
      recording upon the occurrence of a bankruptcy, insolvency or foreclosure
      relating to the Mortgagor under the related Mortgage. Subject to the preceding
      sentence, as soon as practicable after the Closing Date (but in no event more
      than three months thereafter except to the extent delays are caused by the
      applicable recording office), the Master Servicer, at the expense of the
      Depositor and with the cooperation of the applicable Servicer, shall cause
      to be
      properly recorded by such Servicer in each public recording office where the
      related Mortgages are recorded each Assignment of Mortgage referred to in
      subsection (b)(v) above with respect to each Non-MERS Mortgage Loan. With
      respect to each Cooperative Loan, the Master Servicer, at the expense of the
      Depositor and with the cooperation of the applicable Servicer, shall cause

      to
      perfect the interest of the Trustee in the related Mortgaged
      Property.

    (ii) With
      respect to each MERS Mortgage Loan, the Master Servicer, at the expense of
      the
      Depositor and with the cooperation of the Servicer, shall cause the Servicer
      to
      take such actions as are necessary to cause the Trustee to be clearly identified
      as the owner of each such Mortgage Loan on the records of MERS for purposes
      of
      the system of recording transfers of beneficial ownership of mortgages
      maintained by MERS.

      instances where a Title Insurance Policy is required to be delivered to the
      Trustee or the Custodian on behalf of the Trustee under clause (b)(vii) above
      and is not so delivered, the Depositor will provide a copy of such Title
      Insurance Policy to the Trustee, or to the Custodian on behalf of the Trustee,
      as promptly as practicable after the execution and delivery hereof, but in
      any
      case within 180 days of the Closing Date.

     

    (e) For
      Mortgage Loans (if any) that have been prepaid in full after the Cut-off Date
      and prior to the Closing Date, the Depositor, in lieu of delivering the above
      documents, herewith delivers to the Trustee, or to the Custodian on behalf
      of
      the Trustee, an Officer’s Certificate which shall include a statement to the
      effect that all amounts received in connection with such prepayment that are
      required to be deposited in the Collection Account pursuant to Section 4.01
      have
      been so deposited. All original documents that are not delivered to the Trustee
      or the Custodian on behalf of the Trustee shall be held by the Master Servicer
      or the applicable Servicer in trust for the benefit of the Trustee and the
      Certificateholders.

    (a) The
      Trustee, by execution and delivery hereof, acknowledges receipt by it or by
      the
      Custodian on its behalf of the Mortgage Files pertaining to the Mortgage Loans
      listed on the Mortgage Loan Schedule, subject to review thereof by the Trustee,
      or by the Custodian on behalf of the Trustee, under this Section 2.02. The
      Trustee, or the Custodian on behalf of the Trustee, will execute and deliver
      to
      the Trustee, the Depositor, the Master Servicer and any NIMS Insurer on the
      Closing Date an Initial Certification in the form annexed hereto as Exhibit
      B-1
      (or in the form annexed to the Custodial Agreement as Exhibit B-1, as
      applicable).

     

    (b) Within
      45
      days after the Closing Date, the Trustee or the Custodian on behalf of the
      Trustee, will, for the benefit of Holders of the Certificates and any NIMS
      Insurer, review each Mortgage File to ascertain that all required documents
      set
      forth in Section 2.01 have been received and appear on their face to contain
      the
      requisite signatures by or on behalf of the respective parties thereto, and
      shall deliver to the Trustee, the Depositor, the Master Servicer and any NIMS
      Insurer an Interim Certification in the form annexed hereto as Exhibit B-2
      (or
      in the form annexed to the applicable Custodial Agreement as Exhibit B-2, as
      applicable) to the effect that, as to each Mortgage Loan listed in the Mortgage
      Loan Schedule (other than any Mortgage Loan prepaid in full or any specifically
      identified in such certification as not covered by such certification), (i)
      all
      of the applicable documents specified in Section 2.01(b) are in its possession
      and (ii) such documents have been reviewed by it and appear to relate to such
      Mortgage Loan. The Trustee, or the Custodian on behalf of the Trustee, shall
      determine whether such documents are executed and endorsed, but shall be under
      no duty or obligation to inspect, review or examine any such documents,
      instruments, certificates or other papers to determine that the same are valid,
      binding, legally effective, properly endorsed, genuine, enforceable or
      appropriate for the represented purpose or that they have actually been recorded
      or are in recordable form or that they are other than what they purport to
      be on
      their face. Neither the Trustee nor the Custodian shall have any responsibility
      for verifying the genuineness or the legal effectiveness of or authority for
      any
      signatures of or on behalf of any party or endorser.

     

    
      
        
        

      

      
        -56-

        
          

        

      

      
        
        

      

    

     

    (c) If
      in the
      course of the review described in paragraph (b) above the Trustee or the
      Custodian discovers any document or documents constituting a part of a Mortgage
      File that is missing, does not appear regular on its face (i.e., is mutilated,
      damaged, defaced, torn or otherwise physically altered) or appears to be
      unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule (each,
      a “Material Defect”), the Trustee, or the Custodian on behalf of the Trustee,
      discovering such Material Defect shall promptly identify the Mortgage Loan
      to
      which such Material Defect relates in the Interim Certification delivered to
      the
      Trustee, the Depositor, the Master Servicer and any NIMS Insurer. Within 90
      days
      of its receipt of such notice, the Transferor, or, if the Transferor does not
      do
      so, the Depositor shall be required to cure such Material Defect (and, in such
      event, the Depositor shall provide the Trustee with an Officer’s Certificate
      confirming that such cure has been effected). If the applicable Transferor
      or
      the Depositor, as applicable, does not so cure such Material Defect, the
      Transferor, or, if the Transferor does not do so, the Depositor, shall, if
      a
      loss has been incurred with respect to such Mortgage Loan that would, if such
      Mortgage Loan were not purchased from the Trust Fund, constitute a Realized
      Loss, and such loss is attributable to the failure of the Depositor to cure
      such
      Material Defect, repurchase the related Mortgage Loan from the Trust Fund at
      the
      Purchase Price. A loss shall be deemed to be attributable to the failure of
      the
      Depositor to cure a Material Defect if, as determined by the Depositor, upon
      mutual agreement with the Trustee each acting in good faith, absent such
      Material Defect, such loss would not have been incurred. Within the two-year
      period following the Closing Date, the Depositor may, in lieu of repurchasing
      a
      Mortgage Loan pursuant to this Section 2.02, substitute for such Mortgage Loan
      a
      Qualifying Substitute Mortgage Loan subject to the provisions of Section 2.05.
      The failure of the Trustee or the Custodian to give the notice contemplated
      herein within 45 days after the Closing Date shall not affect or relieve the
      Depositor of its obligation to repurchase any Mortgage Loan pursuant to this
      Section 2.02 or any other Section of this Agreement requiring the repurchase
      of
      Mortgage Loans from the Trust Fund.

     

    (d) Within
      180 days following the Closing Date, the Trustee, or the Custodian, shall
      deliver to the Trustee, the Depositor, the Master Servicer and any NIMS Insurer
      a Final Certification substantially in the form attached as Exhibit B-3 (or
      in
      the form annexed to the Custodial Agreement as Exhibit B-3, as applicable)
      evidencing the completeness of the Mortgage Files in its possession or control,
      with any exceptions noted thereto.

     

    (e) Nothing
      in this Agreement shall be construed to constitute an assumption by the Trust
      Fund, the Trustee, the Custodian or the Certificateholders of any unsatisfied
      duty, claim or other liability on any Mortgage Loan or to any
      Mortgagor.

     

    
      
        
        

      

      
        -57-

        
          

        

      

      
        
        

      

    

     

    (f) Each
      of
      the parties hereto acknowledges that the Custodian shall perform the applicable
      review of the Mortgage Loans and respective certifications thereof as provided
      in this Section 2.02 and in the Custodial Agreement.

     

    (g) Upon
      execution of this Agreement, the Depositor hereby delivers to the Trustee and
      the Trustee acknowledges a receipt of the Mortgage Loan Sale Agreement and
      the
      Servicing Agreement.

      or
      order binding on the Depositor or its properties or the certificate of
      incorporation or bylaws of the Depositor;

     

    (iii) the
      execution, delivery and performance by the Depositor of this Agreement and

      to
      (A) applicable bankruptcy and insolvency laws and other similar laws affecting
      the enforcement of the rights of creditors generally and (B) general principles
      of equity regardless of whether such enforcement is considered in a proceeding
      in equity or at law;

     

    (v) there
      are
      no actions, suits or proceedings pending or, to the knowledge of the Depositor,
      threatened or likely to be asserted against or affecting the Depositor, before
      or by any court, administrative agency, arbitrator or governmental body (A)
      with
      respect to any of the transactions contemplated by this Agreement or (B) with
      respect to any other matter which in the judgment of the Depositor will be
      determined adversely to the Depositor and will if determined adversely to the
      Depositor materially and adversely affect it or its business, assets, operations
      or condition, financial or otherwise, or adversely affect its ability to perform
      its obligations under this Agreement; and

     

    
      
        
        

      

      
        -58-

      Depositor was the sole owner of record and holder of each Mortgage Loan, and
      the
      Depositor had good and marketable title thereto, and had full right to transfer
      and sell each Mortgage Loan to the Trustee free and clear, subject only to
      (1)
      liens of current real property taxes and assessments not yet due and payable
      and, if the related Mortgaged Property is a condominium unit, any lien for
      common charges permitted by statute, (2) covenants, conditions and restrictions,
      rights of way, easements and other matters of public record as of the date
      of
      recording of such Mortgage acceptable to mortgage lending institutions in the
      area in which the related Mortgaged Property is located and specifically
      referred to in the lender’s Title Insurance Policy or attorney’s opinion of
      title and abstract of title delivered to the originator of such Mortgage Loan,
      and (3) such other matters to which like properties are commonly subject which
      do not, individually or in the aggregate, materially interfere with the benefits
      of the security intended to be provided by the Mortgage, of any encumbrance,
      equity, participation interest, lien, pledge, charge, claim or security
      interest, and had full right and authority, subject to no interest or
      participation of, or agreement with, any other party, to sell and assign each
      Mortgage Loan pursuant to this Agreement.

     

    (b) The
      representations and warranties of the Transferor with respect to the related
      Mortgage Loans in the applicable Transfer Agreement, which have been assigned
      to
      the Trustee hereunder, were made as of the date specified in the applicable
      Transfer Agreement (or underlying agreement, if such Transfer Agreement is
      in
      the form of an assignment of a prior agreement). To the extent that any fact,
      condition or event with respect to a Mortgage Loan constitutes a breach of
      both
      (i) a representation or warranty of the applicable Transferor under the
      applicable Transfer Agreement and (ii) a representation or warranty of the
      Seller under the Mortgage Loan Sale Agreement, the only right or remedy of
      the
      Trustee or any Certificateholder hereunder (other than a breach by the Seller
      of
      the representations made pursuant to Sections 1.04(b)(xii), 1.04(b)(xvii),
      1.04(b)(xviii), 1.04(b)(ix) and 1.04(b)(xx) of the Mortgage Loan Sale Agreement)
      shall be their rights to enforce the obligations of the applicable Transferor
      under any applicable representation or warranty made by it. Pursuant to the
      terms of the Mortgage Loan Sale Agreement, the representations and warranties
      made by the Seller pursuant to Sections 1.04(b)(xii), 1.04(b)(xvii),
      1.04(b)(xviii), 1.04(b)(ix) and 1.04(b)(xx) of the Mortgage Loan Sale Agreement
      shall be the direct obligations of the Seller. With the exception of the
      immediately proceeding sentence, the Seller shall not have any other obligation
      or liability with respect to any breach of a representation or warranty made
      by
      it with respect to the Mortgage Loans sold by it if the fact, condition or
      event
      constituting such breach also constitutes a breach of a representation or
      warranty made by the applicable Transferor in the applicable Transfer Agreement,
      without regard to whether such Transferor fulfills its contractual obligations
      in respect of such representation or warranty. The Depositor shall have no
      obligation or liability with respect to any breach of any representation or
      warranty with respect to the Mortgage Loans (except as set forth in Section
      2.03(a)(vi)) under any circumstances.

    Section
      2.04. Discovery
      of Breach

     

    It
      is
      understood and agreed that the representations and warranties (i) set forth
      in
      Section 2.03, (ii) of the Seller set forth in the Mortgage Loan Sale Agreement
      and assigned to the Depositor by the Seller under the Mortgage Loan Sale
      Agreement and to the Trustee by the Depositor hereunder and (iii) of the
      Transferor and of the Servicer assigned by the Seller to the Depositor pursuant
      to the Mortgage Loan Sale Agreement and assigned to the Trustee by the Depositor
      hereunder, shall each survive delivery of the Mortgage Files and the Assignment
      of Mortgage of each Mortgage Loan to the Trustee and shall continue throughout
      the term of this Agreement. Upon discovery by any of the Depositor, any NIMS
      Insurer, the Master Servicer or the Trustee of a breach of any of such
      representations and warranties that materially and adversely affects the value
      of the related Mortgage Loan, the party discovering such breach shall give
      prompt written notice to the other parties; provided, to the extent that
      knowledge of such breach with respect to any Mortgage Loan is known by any
      officer, director, employee or agent of Aurora acting in any capacity other
      than
      as Master Servicer hereunder, the Master Servicer shall not be deemed to have
      knowledge of any such breach until an officer of Aurora acting in a capacity
      as
      Master Servicer has actual knowledge thereof. Within 90 days of the discovery
      of
      a breach of any representation or warranty given to the Trustee by the Depositor
      or given by a Transferor or the Seller and assigned to the Trustee, the
      Depositor, such Transferor or the Seller, as applicable, shall either (a) cure
      such breach in all material respects, (b) repurchase such Mortgage Loan or
      any
      property acquired in respect thereof from the Trustee at the Purchase Price
      (or,
      with respect to Mortgage Loans as to which there is a breach of a representation
      or warranty set forth in Section 1.04(b)(v) of the Mortgage Loan Sale Agreement,
      at the purchase price therefor paid by the Seller under the Mortgage Loan Sale
      Agreement) or (c) within the two-year period following the Closing Date,
      substitute a Qualifying Substitute Mortgage Loan for the affected Mortgage
      Loan.
      In the event of discovery of a breach of any representation and warranty of
      a
      Transferor assigned to the Trustee, the Trustee shall enforce its rights under
      the applicable Transfer Agreement and the Mortgage Loan Sale Agreement for
      the
      benefit of Certificateholders. As provided in the Mortgage Loan Sale Agreements,
      if a Transferor substitutes a mortgage loan for a Deleted Mortgage Loan pursuant
      to the Transfer Agreement and such substitute mortgage loan is not a Qualifying
      Substitute Mortgage Loan, then pursuant to the terms of the Mortgage Loan Sale
      Agreement the Seller will, in exchange for such substitute mortgage loan, (i)
      pay to the Trust Fund the applicable Purchase Price for the affected Mortgage
      Loan or (ii) within two years of the Closing Date, substitute a Qualifying
      Substitute Mortgage Loan.

     

    Section
      2.05. Repurchase,
      Purchase or Substitution of Mortgage Loans

     

    (a) With
      respect to any Mortgage Loan repurchased by the Depositor pursuant to this
      Agreement, by the Seller pursuant to the Mortgage Loan Sale Agreement, or by
      the
      Transferor pursuant to the applicable Transfer Agreement, the principal portion
      of the funds received by the Master Servicer in respect of such repurchase
      of a
      Mortgage Loan will be considered a Principal Prepayment and the Purchase Price
      shall be deposited in the Collection Account or a Custodial Account, as
      applicable. The Trustee (i) upon receipt of the full amount of the Purchase
      Price for a Deleted Mortgage Loan, (ii) upon receipt of a written certification
      from the Master Servicer that it has received the full amount of the Purchase
      Price for a Deleted Mortgage Loan and has deposited such amount in the
      Collection Account or (iii) upon receipt of notification from the Custodian
      that
      it had received the Mortgage File for a Qualifying Substitute Mortgage Loan
      substituted for a Deleted Mortgage Loan (and any applicable Substitution
      Amount), shall release or cause to be released and reassign to the Depositor,
      the Seller or the Transferor, as applicable, the related Mortgage File for
      the
      Deleted Mortgage Loan and shall execute and deliver such instruments of transfer
      or assignment, in each case without recourse, representation or warranty, as
      shall be necessary to vest in such party or its designee or assignee title
      to
      any Deleted Mortgage Loan released pursuant hereto, free and clear of all
      security interests, liens and other encumbrances created by this Agreement,
      which instruments shall be prepared by the applicable Servicer and the Trustee
      shall have no further responsibility with respect to the Mortgage File relating
      to such Deleted Mortgage Loan. The Seller indemnifies and holds the Trust Fund,
      the Master Servicer, the Trustee, the Depositor and each Certificateholder
      harmless against any and all taxes, claims, losses, penalties, fines,
      forfeitures, reasonable legal fees and related costs, judgments, and any other
      costs, fees and expenses that the Trust Fund, the Trustee, the Master Servicer,
      the Depositor and any Certificateholder may sustain in connection with any
      actions of the Seller relating to a repurchase of a Mortgage Loan other than
      in
      compliance with the terms of this Section 2.05 and the Mortgage Loan Sale
      Agreement, to the extent that any such action causes an Adverse REMIC
      Event.

     

    
      
        
        

      

      
        -60-

        
          

        

      

      
        
        

      

    

     

    (b) With
      respect to each Qualifying Substitute Mortgage Loan to be delivered to the
      Trustee (or the Custodian) pursuant to the terms of this Article II in exchange
      for a Deleted Mortgage Loan: (i) the Depositor, the Transferor or the Seller,
      as
      applicable, must deliver to the Trustee (or the Custodian) the Mortgage File
      for
      the Qualifying Substitute Mortgage Loan containing the documents set forth
      in
      Section 2.01(b) along with a written certification certifying as to the delivery
      of such Mortgage File and containing the granting language set forth in Section
      2.01(a); and (ii) the Depositor will be deemed to have made, with respect to
      such Qualifying Substitute Mortgage Loan, each of the representations and
      warranties made by it with respect to the related Deleted Mortgage Loan. As
      soon
      as practicable after the delivery of any Qualifying Substitute Mortgage Loan
      hereunder, the Master Servicer, at the expense of the Depositor and with the
      cooperation of the applicable Servicer, shall (i) with respect to a Qualifying
      Substitute Mortgage Loan that is a Non-MERS Mortgage Loan, cause the Assignment
      of Mortgage to be recorded by the applicable Servicer if required pursuant
      to
      Section 2.01(c), or (ii) with respect to a Qualifying Substitute Mortgage Loan
      that is a MERS Mortgage Loan, cause to be taken such actions as are necessary
      to
      cause the Trustee to be clearly identified as the owner of each such Mortgage
      Loan on the records of MERS if required pursuant to Section
      2.01(c).

     

    (c) Notwithstanding
      any other provision of this Agreement, the right to substitute Mortgage Loans
      pursuant to this Article II shall be subject to the additional limitations
      that
      no substitution of a Qualifying Substitute Mortgage Loan for a Deleted Mortgage
      Loan shall be made unless the Trustee and the NIMS Insurer have received an
      Opinion of Counsel (at the expense of the party seeking to make the
      substitution) that, under current law, such substitution will not result in
      an
      Adverse REMIC Event.

     

    Section
      2.06. Grant
      Clause

     

    (a) It
      is
      intended that the conveyance of the Depositor’s right, title and interest in and
      to property constituting the Trust Fund pursuant to this Agreement shall
      constitute, and shall be construed as, a sale of such property and not a grant
      of a security interest to secure a loan. However, if such conveyance is deemed
      to be in respect of a loan, it is intended that: (1) the rights and obligations
      of the parties shall be established pursuant to the terms of this Agreement;
      (2)
      the Depositor hereby grants to the Trustee for the benefit of the Holders of
      the
      Certificates a first priority security interest to secure repayment of an
      obligation in an amount equal to the aggregate Class Principal Amount of the
      Certificates in all of the Depositor’s right, title and interest in, to and
      under, whether now owned or hereafter acquired, the Trust Fund and all proceeds
      of any and all property constituting the Trust Fund to secure payment of the
      Certificates and (3) this Agreement shall constitute a security agreement under
      applicable law. If such conveyance is deemed to be in respect of a loan and
      the
      trust created by this Agreement terminates prior to the satisfaction of the
      claims of any Person holding any Certificate, the security interest created
      hereby shall continue in full force and effect and the Trustee shall be deemed
      to be the collateral agent for the benefit of such Person, and all proceeds
      shall be distributed as herein provided.

     

    
      
        
        

      

      
        -61-

        
          

        

      

      
        
        

      

    

     

    (b) The
      Depositor shall, to the extent consistent with this Agreement, take such
      reasonable actions as may be necessary to ensure that, if this Agreement were
      deemed to create a security interest in the Mortgage Loans and the other
      property described above, such security interest would be deemed to be a
      perfected security interest of first priority under applicable law and shall
      be
      maintained as such throughout the term of this Agreement. The Depositor shall,
      at its own expense, make all initial filings on or about the Closing Date and
      shall forward a copy of such filing or filings to the Trustee. Without limiting
      the generality of the foregoing, the Depositor shall prepare and forward for
      filing, or shall cause to be forwarded for filing, at the expense of the
      Depositor, all filings necessary to maintain the effectiveness of any original
      filings necessary under the relevant UCC to perfect the Trustee’s security
      interest in or lien on the Mortgage Loans, including without limitation (x)
      continuation statements, and (y) such other statements as may be occasioned
      by
      (1) any change of name of the Seller, the Depositor or the Trustee, (2) any
      change of location of the jurisdiction of organization of the Seller or the
      Depositor, (3) any transfer of any interest of the Seller or the Depositor
      in
      any Mortgage Loan or (4) any change under the relevant UCC or other applicable
      laws. Neither the Seller nor the Depositor shall organize under the law of
      any
      jurisdiction other than the State under which each is organized as of the
      Closing Date (whether changing its jurisdiction of organization or organizing
      under an additional jurisdiction) without giving 30 days prior written notice
      of
      such action to its immediate and intermediate transferee, including the Trustee.
      Before effecting such change, the Seller or the Depositor proposing to change
      its jurisdiction of organization shall prepare and file in the appropriate
      filing office any financing statements or other statements necessary to continue
      the perfection of the interests of its immediate and mediate transferees,
      including the Trustee, in the Mortgage Loans. In connection with the
      transactions contemplated by this Agreement, the Seller and the Depositor
      authorizes its immediate or mediate transferee to file in any filing office
      any
      initial financing statements, any amendments to financing statements, any
      continuation statements, or any other statements or filings described in this
      paragraph (b).

    ARTICLE
      III.


     

    THE
      CERTIFICATES

     

    Section
      3.01. The
      Certificates

     

    (a) The
      Certificates (other than the Underlying Interests) shall be issuable in
      registered form only and shall be securities governed by Article 8 of the New
      York Uniform Commercial Code. The Book-Entry Certificates will be evidenced
      by
      one or more certificates, beneficial ownership of which will be held in the
      dollar denominations in Certificate Principal Amount (or Notional Amount),
      or in
      the Percentage Interests, specified herein. Each Class of LIBOR Certificates
      (other than the Underlying Interests) and Grantor Trust Certificates will be
      issued in the minimum denominations in Certificate Principal Amount (or Notional
      Amount) specified in the Preliminary Statement hereto and in integral multiples
      of $1 in excess thereof. The Class C, Class P and Class X Certificates shall
      be
      maintained in definitive, fully registered form in a minimum denomination equal
      to 10% of the Percentage Interest of the Class. The Class R Certificate shall
      be
      issued as a single Certificate and maintained in definitive, fully registered
      form in a minimum denomination equal to 100% of the Percentage Interest of
      such
      Class. The Certificates (other than the Underlying Interests) may be issued
      in
      the form of typewritten certificates.

     

    (b) The
      Certificates (other than the Underlying Interests) shall be executed by manual
      or facsimile signature on behalf of the Trustee by an authorized officer. Each
      Certificate (other than the Underlying Interests) shall, on original issue,
      be
      authenticated by the Trustee upon the order of the Depositor upon receipt by
      the
      Trustee of the Mortgage Files described in Section 2.01. No Certificate (other
      than the Underlying Interests) shall be entitled to any benefit under this
      Agreement, or be valid for any purpose, unless there appears on such Certificate
      a certificate of authentication substantially in the form provided for herein,
      executed by an authorized officer of the Trustee or the Authenticating Agent,
      if
      any, by manual signature, and such certification upon any Certificate shall
      be
      conclusive evidence, and the only evidence, that such Certificate has been
      duly
      authenticated and delivered hereunder. All Certificates (other than the
      Underlying Interests) shall be dated the date of their authentication. At any
      time and from time to time after the execution and delivery of this Agreement,
      the Depositor may deliver Certificates executed by the Depositor to the Trustee
      or the Authenticating Agent for authentication and the Trustee or the
      Authenticating Agent shall authenticate and deliver such Certificates as in
      this
      Agreement provided and not otherwise.

     

    Section
      3.02. Registration

     

    The
      Trustee is hereby appointed, and hereby accepts its appointment as, Certificate
      Registrar in respect of the Certificates (other than the Underlying Interests)
      and shall maintain books for the registration and for the transfer of
      Certificates (the “Certificate Register”). The Trustee may appoint a bank or
      trust company to act as Certificate Registrar. A registration book shall be
      maintained for the Certificates collectively. The Certificate Registrar may
      resign or be discharged or removed and a new successor may be appointed in
      accordance with the procedures and requirements set forth in Sections 6.06
      and
      6.07 hereof with respect to the resignation, discharge or removal of the Trustee
      and the appointment of a successor trustee. The Certificate Registrar may
      appoint, by a written instrument delivered to the Holders and the Master
      Servicer, any bank or trust company to act as co registrar under such conditions
      as the Certificate Registrar may prescribe; provided, however, that the
      Certificate Registrar shall not be relieved of any of its duties or
      responsibilities hereunder by reason of such appointment.

     

    
      
        
        

      

      
        -63-

        
          

        

      

      
        
        

      

    

     

    Section
      3.03. Transfer
      and Exchange of Certificates

     

    (a) A
      Certificate (other than Book Entry Certificates, which shall be subject to
      Section 3.09 hereof) may be transferred by the Holder thereof only upon
      presentation and surrender of such Certificate at the office of the Certificate
      Registrar duly endorsed or accompanied by an assignment duly executed by such
      Holder or his duly authorized attorney in such form as shall be satisfactory
      to
      the Certificate Registrar. Upon the transfer of any Certificate in accordance
      with the preceding sentence, the Trustee shall execute, and the Trustee or
      any
      Authenticating Agent shall authenticate and deliver to the transferee, one
      or
      more new Certificates of the same Class and evidencing, in the aggregate, the
      same aggregate Certificate Principal Amount or Percentage Interest as the
      Certificate being transferred. No service charge shall be made to a
      Certificateholder for any registration of transfer of Certificates, but the
      Certificate Registrar may require payment of a sum sufficient to cover any
      tax
      or governmental charge that may be imposed in connection with any registration
      of transfer of Certificates.

     

    (b) A
      Certificate may be exchanged by the Holder thereof for any number of new
      Certificates of the same Class, in authorized denominations, representing in
      the
      aggregate the same Certificate Principal Amount or Percentage Interest as the
      Certificate surrendered, upon surrender of the Certificate to be exchanged
      at
      the office of the Certificate Registrar duly endorsed or accompanied by a
      written instrument of transfer duly executed by such Holder or his duly
      authorized attorney in such form as is satisfactory to the Certificate
      Registrar. Certificates delivered upon any such exchange will evidence the
      same
      obligations, and will be entitled to the same rights and privileges, as the
      Certificates surrendered. No service charge shall be made to a Certificateholder
      for any exchange of Certificates, but the Certificate Registrar may require
      payment of a sum sufficient to cover any tax or governmental charge that may
      be
      imposed in connection with any exchange of Certificates. Whenever any
      Certificates are so surrendered for exchange, the Trustee shall execute, and
      the
      Trustee or the Authenticating Agent shall authenticate, date and deliver the
      Certificates which the Certificateholder making the exchange is entitled to
      receive.

     

    (c) By
      acceptance of a Restricted Certificate or QIB-Restricted Certificate, whether
      upon original issuance or subsequent transfer, each Holder of such a Certificate
      acknowledges the restrictions on the transfer of such Certificate set forth
      thereon and agrees that it will transfer such a Certificate only as provided
      herein. 

     

    The
      following restrictions shall apply with respect to the transfer and registration
      of transfer of a Restricted Certificate to a transferee that takes delivery
      in
      the form of a Definitive Certificate:

     

    (i) The
      Certificate Registrar shall register the transfer of a Restricted Certificate
      if
      the requested transfer is (x) to the Depositor or an affiliate (as defined
      in
      Rule 405 under the Securities Act of 1933, as amended (the “Act”)) of the
      Depositor or (y) being made to a “qualified institutional buyer” (a “QIB”) as
      defined in Rule 144A under the Act by a transferor that has provided the Trustee
      with a certificate in the form of Exhibit F hereto; and

     

    
      
        
        

      

      
        -64-

        
          

        

      

      
        
        

      

    

     

    (ii) The
      Certificate Registrar shall register the transfer of a Restricted Certificate
      if
      the requested transfer is being made to an “accredited investor” under Rule
      501(a)(1), (2), (3) or (7) under the Act, or to any Person all of the equity
      owners in which are such accredited investors, by a transferor who furnishes
      to
      the Trustee a letter of the transferee substantially in the form of Exhibit
      G
      hereto.

     

    (d) No
      transfer of a Grantor Trust Certificate will be registered unless the Trustee,
      the Certificate Registrar and the Depositor receive (A) a representation as
      set
      forth in Exhibit H to the effect that such transferee is not, and is not acting
      for, on behalf of or with any assets of, an employee benefit plan or other
      arrangement subject to Title I of ERISA or plan subject to Section 4975 of
      the
      Code, or (ii) until the termination of the applicable Deferred Interest Cap
      Agreement, the acquisition and holding of the Grantor Trust Certificate are
      eligible for exemptive relief under any of Section 408(b)(17) of ERISA or
      Section 4975(d)(20) of the Code, Prohibited Transaction Class Exemption (“PTCE”)
      84-14, PTCE 90-1, PTCE 91-38, PTCE 95-60 or PTCE 96-23, each as amended.


     

    No
      Transfer of an ERISA-Restricted Certificate or a Class R Certificate will be
      registered unless the Trustee, the Certificate Registrar and the Depositor
      receive (A) a representation as set forth in Exhibit D-1 for Class R
      Certificates or Exhibit H for ERISA-Restricted Certificates to the effect that
      such transferee is not an employee benefit plan or other arrangement subject
      to
      Title I of ERISA, a plan subject to Section 4975 of the Code or a plan subject
      to any provisions under any federal, state, local, non-U.S. or other laws or
      regulations that are substantively similar to the foregoing provisions of ERISA
      or the Code (“Similar Law”) (collectively, a “Plan”), and is not directly or
      indirectly acquiring the Class R Certificate for, on behalf of, or with any
      assets of any such Plan, or (B) solely in the case of an ERISA-Restricted
      Certificate (I) a representation as set forth in Exhibit H for ERISA-Restricted
      Certificates that, if the Certificate has been the subject of an
      ERISA-Qualifying Underwriting, such transferee is an insurance company that
      is
      acquiring the Certificate with assets contained in an “insurance company general
      account,” as defined in Section V(e) of Prohibited Transaction Class Exemption
      (“PTCE”) 95-60, and the acquisition and holding of the Certificate are covered
      and exempt under Sections I and III of PTCE 95-60, or (II) solely in the case
      of
      an ERISA-Restricted Certificate that is a Definitive Certificate, an Opinion
      of
      Counsel satisfactory to the Trustee, the Certificate Registrar and the
      Depositor, and upon which the Trustee, the Certificate Registrar and the
      Depositor shall be entitled to rely, to the effect that the acquisition and
      holding of such Certificate will not constitute or result in a nonexempt
      prohibited transaction under ERISA or the Code, or a violation of Similar Law,
      and will not subject the Trustee, the Certificate Registrar, the Master
      Servicer, any Servicer or the Depositor to any obligation in addition to those
      expressly undertaken in this Agreement, which Opinion of Counsel shall not
      be an
      expense of the Trustee, the Certificate Registrar, the Master Servicer, any
      Servicer or the Depositor.

     

    Except
      in
      the case of Definitive Certificates, the representations set forth in the
      preceding paragraphs, other than clause (B)(II) in the immediately preceding
      paragraph, shall be deemed to have been made to the Trustee, the Certificate
      Registrar and the Depositor by the transferee’s acceptance of a Grantor Trust
      Certificate, an ERISA-Restricted Certificate or a Class R Certificate (or the
      acceptance by a Certificate Owner of the beneficial interest in any Class of
      Grantor Trust Certificate, ERISA Restricted Certificate or Class R Certificate).
      The Trustee, the Certificate Registrar and the Depositor shall not have any
      obligation to monitor transfers of Book-Entry Certificates or Restricted Global
      Securities that are Grantor Trust Certificates, ERISA-Restricted Certificates
      or
      Class R Certificates or any liability for transfers of such Certificates in
      violation of the transfer restrictions.

    Notwithstanding
      any other provision herein to the contrary, any purported transfer of a Grantor
      Trust Certificate, an ERISA-Restricted Certificate or Class R Certificate to
      or
      on behalf of a Plan without the delivery to the Trustee, the Certificate
      Registrar and the Depositor of a representation or an Opinion of Counsel
      satisfactory to the Trustee, the Certificate Registrar and the Depositor as
      described above shall be void and of no effect and the next preceding permitted
      beneficial owner will be treated as the beneficial owner of that Certificate,
      retroactive to the date of transfer to the purported beneficial owner. The
      Trustee, the Certificate Registrar and the Depositor shall not have any
      liability to any Person for any registration or transfer of any Grantor
      Trust Certificate, ERISA
      Restricted Certificate or Class R Certificate that is in fact not permitted
      by
      this Section 3.03(d) and the Trustee, the Certificate Registrar and the
      Depositor shall not have any liability for making any payments due on such
      Certificate to the Holder thereof or taking any other action with respect to
      such Holder under the provisions of this Agreement so long as the transfer
      was
      registered by the Certificate Registrar in accordance with the foregoing
      requirements. The Trustee, the Certificate Registrar and the Depositor shall
      be
      entitled, but not obligated, to recover from any Holder of any Grantor Trust
      Certificate, ERISA Restricted Certificate or Class R Certificate that was in
      fact a Plan and that held such Certificate in violation of this Section 3.03(d)
      all payments made on such Grantor Trust Certificate, ERISA Restricted
      Certificate or Class R Certificate at and after the time it commenced such
      holding. Any such payments so recovered shall be paid and delivered to the
      last
      preceding Holder of such Certificate that is not a Plan.

     

    (e) As
      a
      condition of the registration of transfer or exchange of any Certificate, the
      Certificate Registrar may require the certified taxpayer identification number
      of the owner of the Certificate and the payment of a sum sufficient to cover
      any
      tax or other governmental charge imposed in connection therewith; provided,
      however, that the Certificate Registrar shall have no obligation to require
      such
      payment or to determine whether or not any such tax or charge may be applicable.
      No service charge shall be made to the Certificateholder for any registration,
      transfer or exchange of a Certificate.

     

    (f) Notwithstanding
      anything to the contrary contained herein, no Residual Certificate may be owned,
      pledged or transferred, directly or indirectly, by or to (i) a Disqualified
      Organization or (ii) an individual, corporation or partnership or other person
      unless, in the case of clause (ii), such person is (A) not a Non-U.S. Person
      or
      (B) is a Non-U.S. Person that holds a Residual Certificate in connection with
      the conduct of a trade or business within the United States and has furnished
      the transferor and the Trustee with an effective Internal Revenue Service Form
      W-8ECI or successor form at the time and in the manner required by the Code
      (any
      such person who is not covered by clause (A) or (B) above is referred to herein
      as a “Non-permitted Foreign Holder”).

     

    
      
        
        

      

      
        -66-

        
          

        

      

      
        
        

      

    

     

    Prior
      to
      and as a condition of the registration of any transfer, sale or other
      disposition of a Residual Certificate, the proposed transferee shall deliver
      to
      the Trustee an affidavit in substantially the form attached hereto as Exhibit
      D-1 representing and warranting, among other things, that such transferee is
      neither a Disqualified Organization, an agent or nominee acting on behalf of
      a
      Disqualified Organization, nor a Non-permitted Foreign Holder (any such
      transferee, a “Permitted Transferee”), and the proposed transferor shall deliver
      to the Trustee an affidavit in substantially the form attached hereto as Exhibit
      D-2. In addition, the Trustee may (but shall have no obligation to) require,
      prior to and as a condition of any such transfer, the delivery by the proposed
      transferee of an Opinion of Counsel, addressed to the Depositor, the Master
      Servicer, any NIMS Insurer and the Trustee satisfactory in form and substance
      to
      the Depositor, that such proposed transferee or, if the proposed transferee
      is
      an agent or nominee, the proposed beneficial owner, is not a Disqualified
      Organization, agent or nominee thereof, or a Non-permitted Foreign Holder.
      Notwithstanding the registration in the Certificate Register of any transfer,
      sale, or other disposition of a Residual Certificate to a Disqualified
      Organization, an agent or nominee thereof, or Non-permitted Foreign Holder,
      such
      registration shall be deemed to be of no legal force or effect whatsoever and
      such Disqualified Organization, agent or nominee thereof, or Non-permitted
      Foreign Holder shall not be deemed to be a Certificateholder for any purpose
      hereunder, including, but not limited to, the receipt of distributions on such
      Residual Certificate. The Trustee shall not be under any liability to any person
      for any registration or transfer of a Residual Certificate to a Disqualified
      Organization, agent or nominee thereof or Non-permitted Foreign Holder or for
      the maturity of any payments due on such Residual Certificate to the Holder
      thereof or for taking any other action with respect to such Holder under the
      provisions of the Agreement, so long as the transfer was effected in accordance
      with this Section 3.03(f), unless a Responsible Officer of the Trustee shall
      have actual knowledge at the time of such transfer or the time of such payment
      or other action that the transferee is a Disqualified Organization, or an agent
      or nominee thereof, or Non-permitted Foreign Holder. The Trustee shall be
      entitled, but not obligated, to recover from any Holder of a Residual
      Certificate that was a Disqualified Organization, agent or nominee thereof,
      or
      Non-permitted Foreign Holder at the time it became a Holder or any subsequent
      time it became a Disqualified Organization, agent or nominee thereof, or
      Non-permitted Foreign Holder, all payments made on such Residual Certificate
      at
      and after either such times (and all costs and expenses, including but not
      limited to attorneys’ fees, incurred in connection therewith). Any payment (not
      including any such costs and expenses) so recovered by the Trustee shall be
      paid
      and delivered to the last preceding Holder of such Residual
      Certificate.

     

    If
      any
      purported transferee shall become a registered Holder of a Residual Certificate
      in violation of the provisions of this Section 3.03(f), then upon receipt of
      written notice to the Trustee that the registration of transfer of such Residual
      Certificate was not in fact permitted by this Section 3.03(f), the last
      preceding Permitted Transferee shall be restored to all rights as Holder thereof
      retroactive to the date of such registration of transfer of such Residual
      Certificate. The Trustee shall be under no liability to any Person for any
      registration of transfer of a Residual Certificate that is in fact not permitted
      by this Section 3.03(f), for making any payment due on such Certificate to
      the
      registered Holder thereof or for taking any other action with respect to such
      Holder under the provisions of this Agreement so long as the transfer was
      registered upon receipt of the affidavit described in the preceding paragraph
      of
      this Section 3.03(f).

     

    
      
        
        

      

      
        -67-

        
          

        

      

      
        
        

      

    

     

    (g) Each
      Holder or Certificate Owner of a Restricted Certificate, ERISA-Restricted
      Certificate, QIB-Restricted Certificate or Residual Certificate, or an interest
      therein, by such Holder’s or Owner’s acceptance thereof, shall be deemed for all
      purposes to have consented to the provisions of this section.

     

    Section
      3.04. Cancellation
      of Certificates

     

    Any
      Certificate surrendered for registration of transfer or exchange shall be
      cancelled and retained in accordance with normal retention policies with respect
      to cancelled certificates maintained by the Trustee or the Certificate
      Registrar.

     

    Section
      3.05. Replacement
      of Certificates

     

    If
      (i)
      any Certificate is mutilated and is surrendered to the Trustee or any
      Authenticating Agent or (ii) the Trustee or any Authenticating Agent receives
      evidence to its satisfaction of the destruction, loss or theft of any
      Certificate, and there is delivered to any NIMS Insurer and the Trustee or
      the
      Authenticating Agent such security or indemnity as may be required by them
      to
      save each of them harmless, then, in the absence of notice to the Depositor
      and
      any Authenticating Agent that such destroyed, lost or stolen Certificate has
      been acquired by a bona fide purchaser, the Trustee shall execute and the
      Trustee or any Authenticating Agent shall authenticate and deliver, in exchange
      for or in lieu of any such mutilated, destroyed, lost or stolen Certificate,
      a
      new Certificate of like tenor and Certificate Principal Amount. Upon the
      issuance of any new Certificate under this Section 3.05, the Trustee and
      Authenticating Agent may require the payment of a sum sufficient to cover any
      tax or other governmental charge that may be imposed in relation thereto and
      any
      other expenses (including the fees and expenses of the Trustee or the
      Authenticating Agent) connected therewith. Any replacement Certificate issued
      pursuant to this Section 3.05 shall constitute complete and indefeasible
      evidence of ownership in the applicable Trust Fund, as if originally issued,
      whether or not the lost, stolen or destroyed Certificate shall be found at
      any
      time.

     

    Section
      3.06. Persons
      Deemed Owners

     

    Subject
      to the provisions of Section 3.09 with respect to Book Entry Certificates,
      the
      Depositor, the Master Servicer, the Trustee, any NIMS Insurer, the Certificate
      Registrar and any agent of any of them may treat the Person in whose name any
      Certificate is registered upon the books of the Certificate Registrar as the
      owner of such Certificate for the purpose of receiving distributions pursuant
      to
      Sections 5.01 and 5.02 and for all other purposes whatsoever, and neither the
      Depositor, the Master Servicer, the Trustee, any NIMS Insurer, the Certificate
      Registrar nor any agent of any of them shall be affected by notice to the
      contrary.

     

    Section
      3.07. Temporary
      Certificates

     

    (a) Pending
      the preparation of Definitive Certificates, upon the order of the Depositor,
      the
      Trustee shall execute and shall authenticate and deliver temporary Certificates
      that are printed, lithographed, typewritten, mimeographed or otherwise produced,
      in any authorized denomination, substantially of the tenor of the Definitive
      Certificates in lieu of which they are issued and with such variations as the
      authorized officers executing such Certificates may determine, as evidenced
      by
      their execution of such Certificates.

     

    
      
        
        

      

      
        -68-

        
          

        

      

      
        
        

      

    

     

    (b) If
      temporary Certificates are issued, the Depositor will cause Definitive
      Certificates to be prepared without unreasonable delay. After the preparation
      of
      Definitive Certificates, the temporary Certificates shall be exchangeable for
      Definitive Certificates upon surrender of the temporary Certificates at the
      office or agency of the Trustee without charge to the Holder. Upon surrender
      for
      cancellation of any one or more temporary Certificates, the Trustee shall
      execute and authenticate and deliver in exchange therefor a like aggregate
      Certificate Principal Amount of Definitive Certificates of the same Class in
      the
      authorized denominations. Until so exchanged, the temporary Certificates shall
      in all respects be entitled to the same benefits under this Agreement as
      Definitive Certificates of the same Class.

     

    Section
      3.08. Appointment
      of Paying Agent

     

    (a) The
      Trustee hereby appoints itself as Paying Agent. The Trustee may appoint a
      successor Paying Agent acceptable to the NIMS Insurer, for the purpose of making
      distributions to Certificateholders hereunder. The Trustee shall cause such
      Paying Agent (if other than the Trustee) to execute and deliver to the Trustee
      an instrument in which such Paying Agent shall agree with the Trustee that
      such
      Paying Agent will hold all sums held by it for the payment to Certificateholders
      in an Eligible Account in trust for the benefit of the Certificateholders
      entitled thereto until such sums shall be paid to the Certificateholders. All
      funds remitted by the Trustee to any such Paying Agent for the purpose of making
      distributions shall be paid to Certificateholders on each Distribution Date
      and
      any amounts not so paid shall be returned on such Distribution Date to the
      Trustee. If the Paying Agent is not the Trustee, the Trustee shall cause to
      be
      remitted to the Paying Agent on or before the Business Day prior to each
      Distribution Date, by wire transfer in immediately available funds, the funds
      to
      be distributed on such Distribution Date. 

     

    (b) Any
      Paying Agent shall be either a bank or trust company or otherwise authorized
      under law to exercise corporate trust powers. A Paying Agent shall comply with
      its reporting obligations under Regulation AB with respect to the Trust Fund
      in
      form and substance similar to those of the Trustee pursuant to Section 6.20,
      and
      the related assessment of compliance shall cover, at a minimum, the matters
      indicated as obligations with respect to the Paying Agent on Exhibit R attached
      hereto. In addition, the Paying Agent (if other than the Trustee) shall notify
      the Sponsor, the Master Servicer and the Depositor within five (5) calendar
      days
      of knowledge thereof (i) of any legal proceedings pending against the Paying
      Agent of the type described in Item 1117
      (§
      229.1117) of Regulation AB, (ii) any merger, consolidation or sale of
      substantially all of the assets of the Paying Agent and (iii) if the Paying
      Agent shall become (but only to the extent not previously disclosed) at any
      time
      an Affiliate of any of the parties listed on Exhibit S hereto or any of their
      Affiliates.

     

    (c) Any
      Paying Agent (if other than the Trustee) agrees to indemnify the Depositor,
      the
      Trustee (if other than the Paying Agent) and the Master Servicer, and each
      of
      their respective directors, officers, employees and agents and the Trust Fund
      and hold each of them harmless from and against any losses, damages, penalties,
      fines, forfeitures, legal fees and expenses and related costs, judgments, and
      any other costs, fees and expenses that any of them may sustain arising out
      of
      or based upon the failure by such Paying Agent to deliver any information,
      report or certification when and as required under Section 6.20 and Section
      9.25(a), provided, however, that this sentence shall not apply if the Paying
      Agent is the Trustee. This indemnification shall survive the termination of
      this
      Agreement or the termination of such Paying Agent hereunder.

     

    
      
        
        

      

      
        -69-

        
          

        

      

      
        
        

      

    

     

    Section
      3.09. Book
      Entry Certificates

     

    (a) Each
      Class of Book Entry Certificates, upon original issuance, shall be issued in
      the
      form of one or more typewritten Certificates representing the Book Entry
      Certificates. The Book Entry Certificates shall initially be registered on
      the
      Certificate Register in the name of the nominee of the Clearing Agency, and
      no
      Certificate Owner will receive a Definitive Certificate representing such
      Certificate Owner’s interest in the Book Entry Certificates, except as provided
      in Section 3.09(c). Unless Definitive Certificates have been issued to
      Certificate Owners of Book Entry Certificates pursuant to Section
      3.09(c):

     

    (i) the
      provisions of this Section 3.09 shall be in full force and effect;

     

    (ii) the
      Depositor, the Master Servicer, the Paying Agent, the Registrar and the Trustee
      may deal with the Clearing Agency for all purposes (including the making of
      distributions on the Book Entry Certificates) as the authorized representatives
      of the Certificate Owners and the Clearing Agency shall be responsible for
      crediting the amount of such distributions to the accounts of such Persons
      entitled thereto, in accordance with the Clearing Agency’s normal
      procedures;

     

    (iii) to
      the
      extent that the provisions of this Section 3.09 conflict with any other
      provisions of this Agreement, the provisions of this Section 3.09 shall control;
      and

     

    (iv) the
      rights of Certificate Owners shall be exercised only through the Clearing Agency
      and the Clearing Agency Participants and shall be limited to those established
      by law and agreements between such Certificate Owners and the Clearing Agency
      and/or the Clearing Agency Participants. Unless and until Definitive
      Certificates are issued pursuant to Section 3.09(c), the initial Clearing Agency
      will make book entry transfers among the Clearing Agency Participants and
      receive and transmit distributions of principal of and interest on the Book
      Entry Certificates to such Clearing Agency Participants.

     

    (b) Whenever
      notice or other communication to the Certificateholders is required under this
      Agreement, unless and until Definitive Certificates shall have been issued
      to
      Certificate Owners pursuant to Section 3.09(c), the Trustee shall give all
      such
      notices and communications specified herein to be given to Holders of the Book
      Entry Certificates to the Clearing Agency.

     

    (c) If
      (i)
      (A) the Depositor advises the Trustee in writing that the Clearing Agency is
      no
      longer willing or able to discharge properly its responsibilities with respect
      to the Book-Entry Certificates, and (B) the Trustee or the Depositor is unable
      to locate a qualified successor, or (ii) after the occurrence of an Event of
      Default, Certificate Owners representing beneficial interests aggregating not
      less than 50% of the Class Principal Amount of a Class of Book Entry
      Certificates identified as such to the Trustee by an Officer’s Certificate from
      the Clearing Agency advise the Trustee and the Clearing Agency through the
      Clearing Agency Participants in writing that the continuation of a book entry
      system through the Clearing Agency is no longer in the best interests of the
      Certificate Owners of a Class of Book Entry Certificates, the Trustee shall
      notify or cause the Certificate Registrar to notify the Clearing Agency to
      effect notification to all Certificate Owners, through the Clearing Agency,
      of
      the occurrence of any such event and of the availability of Definitive
      Certificates to Certificate Owners requesting the same. Upon surrender to the
      Trustee of the Book Entry Certificates by the Clearing Agency, accompanied
      by
      registration instructions from the Clearing Agency for registration, the Trustee
      shall issue the Definitive Certificates. Neither the Depositor nor the Trustee
      shall be liable for any delay in delivery of such instructions and may
      conclusively rely on, and shall be protected in relying on, such instructions.
      Upon the issuance of Definitive Certificates all references herein to
      obligations imposed upon or to be performed by the Clearing Agency shall be
      deemed to be imposed upon and performed by the Trustee, to the extent
      applicable, with respect to such Definitive Certificates and the Trustee shall
      recognize the holders of the Definitive Certificates as Certificateholders
      hereunder.

    (a) On
      the
      Closing Date, the Master Servicer shall open and shall thereafter maintain
      a
      segregated account held in trust (the “Collection Account”), entitled “Aurora
      Loan Services LLC, as Master Servicer, in trust for the benefit of the Holders
      of GreenPoint Mortgage Funding Trust Mortgage Pass-Through Certificates, Series
      2006-AR8.” The Collection Account shall relate solely to the Certificates issued
      by the Trust Fund hereunder, and funds in such Collection Account shall not
      be
      commingled with any other monies.

     

    (b) The
      Collection Account shall be an Eligible Account. If an existing Collection
      Account ceases to be an Eligible Account, the Master Servicer shall establish
      a

      all funds and investment property on deposit in such existing Collection Account
      into such new Collection Account.

     

    (c) The
      Master Servicer shall give to the Trustee and any NIMS Insurer prior written
      notice of the name and address of the depository institution at which the
      Collection Account is maintained and the account number of such Collection
      Account. The Master Servicer shall take such actions as are necessary to cause
      the depository institution holding the Collection Account to hold such account
      in the name of the Master Servicer under this Agreement. No later than 2:00
      p.m.
      New York City time on each Deposit Date, the entire amount on deposit in the
      Collection Account (subject to permitted withdrawals set forth in Section 4.02),
      other than amounts not included in the Total Distribution Amount for such
      Distribution Date, shall be remitted to the Trustee for deposit into the
      Certificate Account by wire transfer in immediately available funds. The Master
      Servicer, at its option (but with prior notice to the Trustee), may choose
      to
      make daily remittances from the Collection Account to the Trustee for deposit
      into the Certificate Account.

     

    (d) The
      Master Servicer shall deposit or cause to be deposited into the Collection
      Account, no later than the second Business Day following the Closing Date,
      any
      amounts received with respect to the Mortgage Loans representing Scheduled
      Payments on the Mortgage Loans due after the Cut-off Date and unscheduled
      payments received on or after the Cut-off Date and on or before the Closing

      Business Days following receipt thereof, the following amounts received or
      payments made by it (other than in respect of principal of and interest on

      collections, and any Prepayment Premiums, on the Mortgage Loans;

    (ii) all
      payments on account of interest on the Mortgage Loans, in all cases, net of
      the
      General Servicing Fee with respect to each such Mortgage Loan, but only to
      the
      extent of the amount permitted to be withdrawn or withheld from the Collection
      Account in accordance with Sections 5.04 and 9.21;

     

    (iii) any
      unscheduled payment or other recovery with respect to a Mortgage Loan not
      otherwise specified in this paragraph (d), including any Subsequent Recovery,
      all Net Liquidation Proceeds with respect to the Mortgage Loans and REO
      Property, and all amounts received in connection with the operation of any
      REO
      Property, net of (x) any unpaid General Servicing Fees with respect to such
      Mortgage Loans (but only to the extent of the amount permitted to be withdrawn
      or withheld from the Collection Account in accordance with Sections 5.04 and
      9.21) and (y) any amounts reimbursable to the applicable Servicer with respect
      to such Mortgage Loan under the related Servicing Agreement and retained by
      such
      Servicer;

     

    (iv) all
      Insurance Proceeds;

      to
      any Qualifying Substitute Mortgage Loan and any purchase price paid by any
      NIMS
      Insurer for the purchase of any Distressed Mortgage Loan under Section
      7.04.

     

    (e) Funds
      in
      the Collection Account may be invested in Eligible Investments selected by
      and
      at the written direction of the Master Servicer, which shall mature not later
      than one Business Day prior to the Deposit Date (except that if such Eligible
      Investment is an obligation of the Trustee, then such Eligible Investment shall
      mature not later than such applicable Deposit Date) and any such Eligible
      Investment shall not be sold or disposed of prior to its maturity. All such
      Eligible Investments shall be made in the name of the Master Servicer in trust
      for the benefit of the Trustee, the Holders of GreenPoint Mortgage Funding
      Trust
      Mortgage Pass-Through Certificates, Series 2006-AR8. All income and gain
      realized from any Eligible Investment shall be for the benefit of the Master
      Servicer and shall be subject to its withdrawal or order from time to time
      and
      shall not be part of the Trust Fund. The amount of any losses incurred in
      respect of any such investments shall be deposited in such Collection Account
      by
      the Master Servicer out of its own funds, without any right of reimbursement
      therefor, immediately as realized. The foregoing requirements for deposit in
      the
      Collection Account are exclusive, it being understood and agreed that, without
      limiting the generality of the foregoing, payments of interest on funds in
      the
      Collection Account and payments in the nature of late payment charges,
      assumption fees, prepayment penalties with respect to mortgages for which the
      Seller does not own the servicing rights, and other incidental fees and charges
      relating to the Mortgage Loans (other than Prepayment Premiums) need not be
      deposited by the Master Servicer in the Collection Account and may be retained
      by the Master Servicer or the applicable Servicer as additional servicing
      compensation. If the Master Servicer deposits in the Collection Account any
      amount not required to be deposited therein, it may at any time withdraw such
      amount from such Collection Account.

    Section
      4.02. Application
      of Funds in the Collection Account

     

    (a) The
      Master Servicer may, from time to time, make, or cause to be made, withdrawals
      from the Collection Account for the following purposes:

     

    (i) to
      reimburse itself or any Servicer for Advances or Servicing Advances made by
      it
      or by such Servicer pursuant to Section 5.04 or the applicable Servicing
      Agreement; such right to reimbursement pursuant to this sub-clause (i) is
      limited to amounts received on or in respect of a particular Mortgage Loan
      (including, for this purpose, Liquidation Proceeds and amounts representing
      Insurance Proceeds with respect to the property subject to the related Mortgage)
      which represent late recoveries (net of the General Servicing Fee) of payments
      of principal or interest respecting which any such Advance was made, it being
      understood, in the case of any such reimbursement, that the Master Servicer’s or
      Servicer’s right thereto shall be prior to the rights of the
      Certificateholders;

     

    (ii) to
      reimburse itself or any Servicer, following a final liquidation of a Mortgage
      Loan (except as otherwise provided in the applicable Servicing Agreement) for
      any previously unreimbursed Advances or Servicing Advances made by it or by
      such
      Servicer (A) that it or such Servicer determines in good faith will not be
      recoverable from amounts representing late recoveries of payments of principal
      or interest respecting the particular Mortgage Loan as to which such Advance
      or
      Servicing Advance was made or from Liquidation Proceeds or Insurance Proceeds
      with respect to such Mortgage Loan and/or (B) to the extent that such
      unreimbursed Advances or Servicing Advances exceed the related Liquidation
      Proceeds or Insurance Proceeds, it being understood, in the case of each such
      reimbursement, that such Master Servicer’s or Servicer’s right thereto shall be
      prior to the rights of the Certificateholders;

     

    (iii) to
      reimburse itself or any Servicer from Liquidation Proceeds for Liquidation
      Expenses and for amounts expended by it pursuant to Sections 9.20 and 9.22(c)
      or
      the applicable Servicing Agreement in good faith in connection with the
      restoration of damaged property and, to the extent that Liquidation Proceeds
      after such reimbursement exceed the unpaid principal balance of the related
      Mortgage Loan, together with accrued and unpaid interest thereon at the
      applicable Mortgage Rate less the General Servicing Fee Rate for such Mortgage
      Loan to the Due Date next succeeding the date of its receipt of such Liquidation
      Proceeds, to pay to itself out of such excess the amount of any unpaid
      assumption fees, late payment charges or other Mortgagor charges on the related
      Mortgage Loan and to retain any excess remaining thereafter as additional
      servicing compensation, it being understood, in the case of any such
      reimbursement or payment, that such Master Servicer’s or Servicer’s right
      thereto shall be prior to the rights of the Certificateholders;

     

    
      
        
        

      

      
        -73-

        
          

        

      

      
        
        

      

    

     

    (iv) [Reserved];

     

    (v) to
      reimburse itself or any Servicer for expenses incurred by and recoverable by
      or
      reimbursable to it or such Servicer pursuant to Sections 9.04, 9.05, 9.06,
      9.07(a), 9.16, 9.30 or 11.15 or pursuant to the applicable Servicing
      Agreement;

     

    (vi) to
      pay to
      the Depositor, the Seller or the Transferor, as applicable, with respect to
      each
      Mortgage Loan or REO Property acquired in respect thereof that has been
      purchased pursuant to this Agreement, all amounts received thereon and not
      distributed on the date on which the related repurchase was effected, and to
      pay
      to the applicable Person any Advances and Servicing Advances to the extent
      specified in the definition of Purchase Price;

     

    (vii) subject
      to Section 5.05, to pay to itself income earned on the investment of funds
      deposited in the Collection Account;

     

    (viii) to
      make
      payments to the Trustee on each Deposit Date for deposit into the Certificate
      Account in the amount provided in Section 4.04;

     

    (ix) to
      make
      payment to itself, the Trustee and others pursuant to any other provision of
      this Agreement and to reimburse any Custodian pursuant to the Custodial
      Agreement, but only to the extent that the items reimbursed constitute
“unanticipated expenses” within the meaning of Treasury Regulation Section
      1.860G-1(b)(3)(ii);

     

    (x) to
      withdraw funds deposited in error in the Collection Account;

     

    (xi) to
      clear
      and terminate the Collection Account pursuant to Section 7.02;

     

    (xii) to
      reimburse the Trustee and a successor master servicer (solely in its capacity
      as
      successor master servicer), for any fee or advance occasioned by a termination
      of the Master Servicer, and the assumption of such duties by the Trustee or
      a
      successor master servicer appointed by the Trustee pursuant to Section 6.14,
      in
      each case to the extent not reimbursed by the terminated Master Servicer, it
      being understood, in the case of any such reimbursement or payment, that the
      right of the Master Servicer or the Trustee thereto shall be prior to the rights
      of the Certificateholders; and

     

    (xiii) to
      reimburse any Servicer for such amounts as are due thereto under the applicable
      Servicing Agreement and have not been retained by or paid to such Servicer,
      to
      the extent provided in such Servicing Agreement.

     

    If
      provided in its applicable Servicing Agreement, a Servicer shall be entitled
      to
      retain as additional servicing compensation any Prepayment Interest Excess
      (to
      the extent not offset by Prepayment Interest Shortfalls).

     

    
      
        
        

      

      
        -74-

        
          

        

      

      
        
        

      

    

     

    In
      the
      event that the Master Servicer fails on any Deposit Date to remit to the Trustee
      any amounts required to be so remitted to the Trustee pursuant to sub-clause
      (viii) by such date, the Master Servicer shall pay the Trustee, for the account
      of the Trustee, interest calculated at the “prime rate” (as published in the
“Money Rates” section of The Wall Street Journal) on such amounts not timely
      remitted for the period from and including that Deposit Date to but not
      including the related Distribution Date. The Master Servicer shall only be
      required to pay the Trustee interest for the actual number of days such amounts
      are not timely remitted (e.g., one day’s interest, if such amounts are remitted
      one day after the Deposit Date).

     

    In
      connection with withdrawals pursuant to sub-clauses (i), (ii), (iii), and (vi)
      above, the Master Servicer’s, any Servicer’s or such other Person’s entitlement
      thereto is limited to collections or other recoveries on the related Mortgage
      Loan. The Master Servicer shall therefore keep and maintain a separate
      accounting for each Mortgage Loan it master services for the purpose of
      justifying any withdrawal from the Collection Account it maintains pursuant
      to
      such sub-clause (i), (ii), (iii) and (vi).

     

    Any
      withdrawals described in this section shall be allocated and limited to
      collections or other recoveries on the related Mortgage Pool and shall be
      accounted for in such manner.

     

    (b) The
      Trustee shall afford the NIMS Insurer upon reasonable notice, during normal
      business hours, access to all records maintained by the Trustee in respect
      of
      its duties hereunder and access to officers of the Trustee responsible for
      performing such duties. The Trustee shall cooperate fully with the NIMS Insurer
      and shall make available to the NIMS Insurer for review and copying at the
      expense of the NIMS Insurer such books, documents or records as may be requested
      with respect to the Trustee’s duties hereunder. The NIMS Insurer shall not have
      any responsibility or liability for any action or failure to act by the Trustee
      and is not obligated to supervise the performance of the Trustee under this
      Agreement or otherwise. The Trustee shall also afford the NIMS Insurer, upon
      reasonable notice, during normal business hours, access to the Mortgage Files
      and shall cause the Master Servicer and the Servicer to provide such access
      to
      the Mortgage Files.

    In
      addition to the information listed above for any year in which the Depositor
      is
      subject to Exchange Act reporting with respect to the Certificates, such
      Distribution Date report shall also include such other information as is
      required by Form 10-D, including, but not limited to, the information required
      by Item 1121 (§ 229.1121) of Regulation AB to the extent that the Trustee
      shall have received any such information from the Depositor, the Sponsor, the
      Master Servicer, any Servicer, the Custodian, the Cap Provider or any
      Subservicer or Subcontractor therefor, as applicable, no later than four
      Business Days prior to the Distribution Date.

     

    The
      Trustee will make such report and additional loan level information (and, at
      its
      option, any additional files containing the same information in an alternative
      format) provided to it by the Master Servicer available each month to
      Certificateholders, any NIMS Insurer, and the Rating Agencies via the Trustee’s
      internet website. The Trustee’s internet website shall initially be located at
      http://trustinvestorreporting.com and assistance in using the website can be
      obtained by emailing the Trustee’s customer service desk at
      ct.information.delivery@usbank.com. Such parties that are unable to use the
      website are entitled to have a paper copy mailed to them via first class mail
      by
      calling the customer service desk and indicating such. The Trustee shall have
      the right to change the way such statements are distributed in order to make
      such distribution more convenient and/or more accessible to the above parties
      and the Trustee shall provide timely and adequate notification to all above
      parties regarding any such changes.

     

    The
      Trustee shall provide a “zero settlement file” to Bloomberg L.P. within seven
      (7) calendar days after the receipt of the collateral data file from the
      Depositor, but in no event later than the first Distribution Date, which shall
      contain all of the information in the initial Monthly Report (without giving
      effect to any distributions); provided, however, that in no event will such
      zero
      settlement file contain any mortgagor-specific information.

     

    The
      foregoing information and reports shall be prepared and determined by the
      Trustee based solely on Mortgage Loan data provided to the Trustee by the Master
      Servicer (in a format agreed to by the Trustee and the Master Servicer) no
      later
      than 2:00 p.m. Eastern Time four Business Days prior to the Distribution Date
      or
      such other time period as set forth in Section 9.23(c). In preparing or
      furnishing the foregoing information, the Trustee shall be entitled to rely
      conclusively on the accuracy and completeness of the information or data (i)
      regarding the Mortgage Loans and the related REO Property that has been provided
      to the Master Servicer by the Servicer and to the Trustee by the Master Servicer
      and (ii) regarding the Cap Agreement that has been provided to the Trustee
      by
      the Cap Provider, and the Trustee shall not be obligated to verify, recompute,
      reconcile or recalculate any such information or data. The Trustee shall be
      entitled to conclusively rely on the Mortgage Loan data provided by the Master
      Servicer and shall have no liability for any errors or omissions in such
      Mortgage Loan data.

     

    (b) Upon
      the
      reasonable advance written request of any Certificateholder that is a savings
      and loan, bank or insurance company, the Master Servicer shall provide, or
      cause
      to be provided, to the extent such information is available to the Master
      Servicer exercising reasonable efforts to obtain such information (or, to the
      extent that such information or documentation is not required to be provided
      by
      the applicable Servicer under the related Servicing Agreement, shall use
      reasonable efforts to obtain such information and documentation from such
      Servicer, and provide) to such Certificateholder such reports and access to
      information and documentation regarding the Mortgage Loans as such
      Certificateholder may reasonably deem necessary to comply with applicable
      regulations of the Office of Thrift Supervision or its successor or other
      regulatory authorities with respect to the NIM Securities or an investment
      in
      the Certificates; provided, however, that the Master Servicer shall be entitled
      to be reimbursed by such Certificateholder for the actual expenses incurred
      in
      providing such reports and access.

    (c) Within
      90
      days, or such shorter period as may be required by statute or regulation, after
      the end of each calendar year, the Trustee shall, upon written request, have
      prepared and shall make available to each Person who at any time during the
      calendar year was a Certificateholder of record, and to any NIMS Insurer, and
      make available to Certificate Owners (identified as such by the Clearing Agency)
      in accordance with applicable regulations, a report summarizing the items
      provided to the Certificateholders pursuant to Section 4.03(a)(i) and (ii)
      on an
      annual basis as may be required to enable such Holders to prepare their federal
      income tax returns; provided, however that this Section 4.03(c) shall not be
      applicable where relevant reports or summaries are required elsewhere in this
      Agreement. Such information shall include the amount of original issue discount
      accrued on each Class of Certificates and information regarding the expenses
      of
      the Trust Fund. The Trustee shall be deemed to have satisfied this requirement
      if it forwards such information in any other format permitted by the Code.
      The
      Master Servicer shall provide the Trustee with such information as is necessary
      for the Trustee to prepare such reports.

     

    (d) The
      Trustee shall prepare and file with the IRS, on behalf of the Trust Fund, an
      application for an employer identification number on IRS Form SS-4 or by any
      other acceptable method. The Trustee shall also file a Form 8811 as required.
      The Trustee, upon receipt from the IRS of the Notice of Taxpayer Identification
      Number Assigned, shall upon request promptly forward a copy of such notice
      to
      the Master Servicer and the Depositor. The Trustee shall furnish any other
      information that is required by the Code and regulations thereunder to be made
      available to Certificateholders. The Master Servicer shall provide the Trustee
      with such information (to the extent readily available to the Master Servicer)
      as is necessary for the Trustee to comply with the foregoing.

      the Trustee). All such investments must be payable on demand or mature no later
      than the next Distribution Date, and shall not be sold or disposed of prior
      to
      their maturity. All such Eligible Investments will be made in the name of the

    DISTRIBUTIONS
      TO HOLDERS OF CERTIFICATES

     

    Section
      5.01. Distributions
      Generally

     

    (a) Subject
      to Section 7.01 respecting the final distribution on the Certificates, on each
      Distribution Date the Trustee or the Paying Agent shall make distributions
      in
      accordance with this Article V. Such distributions shall be made by wire
      transfer if the Certificateholder has provided the Trustee with wire
      instructions or by check mailed to the address of such Certificateholder as
      it
      appears in the books of the Trustee if the Certificateholder has not provided
      the Trustee with wire instructions in immediately available funds to an account
      specified in the request and at the expense of such Certificateholder; provided,
      however, that the final distribution in respect of any Certificate shall be
      made
      only upon presentation and surrender of such Certificate at the Corporate Trust
      Office; provided, further, that the foregoing provisions shall not apply to
      any
      Class of Certificates as long as such Certificate remains a Book-Entry
      Certificate in which case all payments made shall be made through the Clearing
      Agency and its Clearing Agency Participants. Notwithstanding such final payment
      of principal of any of the Certificates, each Residual Certificate will remain
      outstanding until the termination of each REMIC and the payment in full of
      all
      other amounts due with respect to the Residual Certificates and at such time
      such final payment in retirement of any Residual Certificate will be made only
      upon presentation and surrender of such Certificate at the Corporate Trust
      Office. If any payment required to be made on the Certificates is to be made
      on
      a day that is not a Business Day, then such payment will be made on the next
      succeeding Business Day.

    (b) All
      distributions or allocations made with respect to Certificateholders within
      each
      Class on each Distribution Date shall be allocated among the outstanding
      Certificates of such Class equally in proportion to their respective initial
      Class Principal Amounts or initial Class Notional Amounts (or Percentage
      Interests).

     

    (c) The
      Trustee shall make payments to Certificateholders and any other person pursuant
      to this Article V based solely on the information set forth in the monthly
      report furnished by the Trustee in accordance with Section 4.03(a), and shall
      be
      entitled to conclusively rely on such information and reports, and on the
      calculations contained therein, when making distributions to Certificateholders.
      The Trustee shall have no liability for any errors in such reports or
      information, and shall not be required to verify, recompute, reconcile or
      recalculate any such information or data.

      basis of Current Interest and Carryforward Interest due such Classes on such
      Distribution Date;

      proportion to the amount of Current Interest and Carryforward Interest that
      would otherwise be distributable thereon) to the extent not paid on such
      Distribution Date pursuant to Sections 5.02(a)(i)(A) and
      5.02(a)(ii)(A);

    (i) On
      each

      a
      Trigger Event is in effect, until the aggregate Certificate Principal Amount

      for
      the benefit of the holders of the Class 1-A3B Certificates, a Balance Guaranteed

      to time from the Cap Provider with respect to each Deferred Interest Cap
      Agreement into the applicable Deferred Interest Cap Account. 

     

    Funds
      in
      the Balance Guaranteed Cap Account and Deferred Interest Cap Accounts shall
      remain uninvested. For federal income tax purposes, the Class 1-A3B Certificates
      shall evidence ownership of the Balance Guaranteed Cap Agreement and the Balance
      Guaranteed Cap Account. For federal income tax purposes, the Class 1-A1A, Class
      1-A1B, Class 1-A3B and Class 2-A Certificates shall each evidence a beneficial
      interest in the Deferred Interest Cap Agreement related to such Class and the
      Deferred Interest Cap Account related to such Deferred Interest Cap Agreement.
      For federal income tax purposes, (i) each Underlying Interest, (ii) the related
      Deferred Interest Cap Agreement, (iii) the related Deferred Interest Cap Account
      and (iv) the related Grantor Trust Certificate Account shall be treated as
      comprising a “grantor trust” within the meaning of the Grantor Trust Provisions
      for the benefit of the holders of the related Grantor Trust
      Certificates.

     

    (i) On
      each
      Distribution Date, the Trustee, as holder of the Underlying Interests, shall
      deposit all distributions received on those Underlying Interests for that
      Distribution Date into the related Grantor Trust Certificate Account. On each
      Distribution Date, the Trustee will withdraw the Grantor Trust Available Funds
      for each Grantor Trust Fund and such amounts will be distributed in the
      following priority:

     

    (i) to
      the
      Cap Provider, interest, if any, on the Cap Deferred Interest Amount due to
      the
      Cap Provider from the applicable Grantor Trust Available Funds;

     

    
      
        
        

      

      
        -89-

        
          

        

      

      
        
        

      

    

     

    (ii) to
      the
      related Grantor Trust Certificates, the Current Interest and any Carryforward
      Interest for such Distribution Date;

     

    (iii) to
      the
      Cap Provider, the Cap Deferred Interest Amount for such Distribution Date from
      the applicable Grantor Trust Available Funds;

     

    (iv) to
      the
      related Grantor Trust Certificates, any principal distributions received from
      the Class
      1-A1A Underlying Interest (in the case of the Class 1-A1A Certificates), Class
      1-A1B Underlying Interest (in the case of the Class 1-A1B Certificates), Class
      1-A3B Underlying Interest (in the case of the Class 1-A3B Certificates) and
      Class 2-A Underlying Interest (in the case of the Class 2-A
      Certificates),
      in
      reduction of the Class Principal Amount of such Grantor Trust Certificates,
      until the Class Principal Amount thereof has been reduced to zero;
      and

     

    (v) to
      the
      Cap Provider, any termination payments (as set forth in the related Deferred
      Interest Cap Agreement) from the applicable Grantor Trust Available
      Funds.

     

    (j) Any
      interest shortfall resulting from Deferred Interest on the Mortgage Loans in
      a
      Mortgage Pool will be allocated to the related LIBOR Certificates, pro
      rata,
      according to the Class Principal Amount of each such Class of related Senior
      Certificates and according to the related Apportioned Principal Balances of
      the
      Subordinate Certificates in reduction of the amount of interest otherwise
      distributable to such Classes of Certificates; provided, however, that to the
      extent the amount of Net Negative Amortization otherwise allocable to such
      Certificates exceeds the amount of Current Interest accrued
      on such Certificates
      (or on
      the Apportioned Principal Balance thereof in the case of the Subordinate
      Certificates),
      then
      such excess Net Negative Amortization shall be allocated to the Class X
      Certificates to the extent payments would otherwise be made to the Class X
      Certificates, and then, if necessary, among the related LIBOR Certificates
      in
      proportion to, and up to, the amount of any remaining interest otherwise
      distributable on the related Senior Certificates and in the case of the
      Subordinate Certificates,
      on
      their respective Apportioned Principal Balances.

     

    The
      amount of the reduction of Current Interest distributable to each Class of
      Certificates attributable to Net Negative Amortization will be added to the
      Class Principal Amount of that Class (other than the Grantor Trust Certificates,
      unless there has been a default in payment under the related Deferred Interest
      Cap Agreement). 

     

    Section
      5.03. Allocation
      of Losses

     

    On
      each
      Distribution Date, the aggregate Class Principal Amount of the Certificates

      following order of priority: 

     

    (i) to

    Section
      5.04. Advances
      by Master Servicer and Trustee

     

    (a) Subject
      to Section 9.07, Advances shall be made in respect of each Determination Date
      as
      provided herein. If, on any Determination Date, the Master Servicer determines
      that any Scheduled Payments due during the related Collection Period (other
      than
      Balloon Payments) and relating to any of the Mortgage Loans have not been
      received, the Master Servicer shall advance such amount; provided, however,
      that
      required Advances remitted by the Master Servicer may be reduced by an amount,
      if any, to be set forth in an Officer’s Certificate to be delivered to the
      Trustee on such Determination Date, which if advanced the Master Servicer has
      determined would not be recoverable from amounts received with respect to such
      Mortgage Loan, including late payments, Liquidation Proceeds, Insurance Proceeds
      or otherwise. If the Master Servicer determines that an Advance is required,
      it
      shall on the Deposit Date immediately following such Determination Date either
      (i) remit to the Trustee from its own funds (or funds advanced by the applicable
      Servicer) for deposit in the Certificate Account immediately available funds
      in
      an amount equal to such Advance, (ii) cause to be made an appropriate entry
      in
      the records of the Collection Account that funds in such account being held
      for
      future distribution or withdrawal have been, as permitted by this Section 5.04,
      used by the Master Servicer to make such Advance, and remit such immediately
      available funds to the Trustee for deposit in the Certificate Account or (iii)
      make Advances in the form of any combination of clauses (i) and (ii) aggregating
      the amount of such Advance. Any funds being held in the Collection Account
      for
      future distribution to Certificateholders and so used shall be replaced by
      the
      Master Servicer from its own funds by remittance to the Trustee for deposit
      in
      the Certificate Account on or before any future Deposit Date to the extent
      that
      funds in the Certificate Account on such Deposit Date shall be less than
      payments to Certificateholders required to be made on the related Distribution
      Date. The Master Servicer shall be entitled to be reimbursed from the Collection
      Account for all Advances made by it as provided in Section 4.02. Notwithstanding
      anything to the contrary herein, in the event the Master Servicer determines
      in
      its reasonable judgment that an Advance is non-recoverable, the Master Servicer
      shall be under no obligation to make such Advance. The Trustee shall be entitled
      to conclusively rely upon any determination by the Master Servicer that an
      Advance, if made, would constitute a non-recoverable Advance.

     

    
      
        
        

      

      
        -91-

        
          

        

      

      
        
        

      

    

     

    (b) In
      the
      event that the Master Servicer fails for any reason to make an Advance required
      to be made pursuant to this Section 5.04 on or before the Deposit Date, the
      Trustee, solely in its capacity as successor master servicer pursuant to Section
      6.14, shall, on or before the related Distribution Date, deposit in the
      Certificate Account an amount equal to the excess of (a) Advances required
      to be
      made by the Master Servicer that would have been deposited in such Certificate
      Account over (b) the amount of any Advance made by the Master Servicer with
      respect to such Distribution Date; provided, however, that the Trustee shall
      be
      required to make such Advance only if it is not prohibited by law from doing
      so
      and it has determined that such Advance would be recoverable from amounts to
      be
      received with respect to such Mortgage Loan, including late payments,
      Liquidation Proceeds, Insurance Proceeds, or otherwise. The Trustee shall be
      entitled to be reimbursed from the Certificate Account for Advances made by
      it
      pursuant to this Section 5.04 as if it were the Master Servicer.

     

    Section
      5.05. Compensating
      Interest Payments

     

    The
      Master Servicer shall be responsible for making all Compensating Interest
      Payments. Any Compensating Interest Payments made by the Master Servicer shall
      be a component of the Interest Remittance Amount. The Servicers shall not be
      responsible for making any Compensating Interest Payments not made by the Master
      Servicer. 

     

    Section
      5.06. Basis
      Risk Reserve Fund

     

    (a) On
      the
      Closing Date, the Trustee shall establish and maintain in its name, in trust
      for
      the benefit of the holders of the Certificates, a 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 Trustee
      held pursuant to this Agreement.

     

    
      
        
        

      

      
        -92-

        
          

        

      

      
        
        

      

    

     

    (b) [Reserved]

     

    (c) Funds
      in
      the Basis Risk Reserve Fund shall be invested in Eligible Investments. The
      Class
      X Certificates shall evidence ownership of the Basis Risk Reserve Fund for
      federal income tax purposes and LBH, on behalf of the Holders thereof, shall
      direct the Trustee, in writing, as to investment of amounts on deposit therein.
      LBH shall be liable for any losses incurred on such investments. In the absence
      of written instructions from LBH as to investment funds on deposit in the Basis
      Risk Reserve Fund, such funds shall remain uninvested.

    Section
      5.11. [Reserved]

     

    Section
      5.12. Class
      X Account

     

    (a) On
      the
      Closing Date, the Trustee shall establish and maintain in its name, in trust
      for
      the benefit of the holders of the Class X Certificates, the Class X Account.
      No
      later than the first date on which any NIM Securities are issued, the Depositor
      may deposit a dollar amount into the Class X Account. The Class X Account 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 Trustee held pursuant to this
      Agreement.

     

    (b) Funds
      in
      the Class X Account may be invested in Eligible Investments having fixed
      maturities described in clauses (i), (iv), (v) or (vii) of the definition
      thereof by the Trustee at the direction of the holders of the Class C
      Certificates maturing on or prior to the next succeeding Distribution Date.
      No
      Eligible Investments shall be acquired or disposed of for the primary purpose
      of
      recognizing gains or decreasing losses from market value changes. Any funds
      held
      in the Class X Account that are not invested shall be held in cash. In the
      absence of such written direction, all funds in the Class X Account shall remain
      uninvested. Any investment earnings on such amounts shall be payable to the
      holders of the Class C Certificates. The Trustee shall account for the Class
      X
      Account as an outside reserve fund within the meaning of Treasury regulation
      1.860G-2(h) and not an asset of any REMIC created pursuant to this Agreement.
      The Class C Certificates shall evidence ownership of the Class X Account for
      federal tax purposes and the Holders thereof shall direct the Trustee in writing
      as to the investment of amounts therein. The Trustee shall have no liability
      for
      losses on investments in Eligible Investments made pursuant to this Section
      5.12(b) (other than as obligor on any such investments). Upon termination of
      the
      Class X Account, any amounts remaining in the Class X Account shall be
      distributed to the Holders of the Class C Certificates in the same manner as
      if
      distributed pursuant to Section 5.02(e)(1) hereof.

     

    
      
        
        

      

      
        -93-

        
          

        

      

      
        
        

      

    

     

    (c) On
      each
      Distribution Date on or prior to the Class X Termination Date, amounts on
      deposit in the Class X Account will be withdrawn and applied to make payments
      on
      the Class X and Class C Certificates, as provided in Section 5.02(e)(1) of
      this
      Agreement. Any amounts that the Trustee is not required to distribute from
      the
      Class X Account pursuant to Section 5.02(e) of this Agreement shall remain
      on
      deposit in the Class X Account.

     

    (d) The
      Class
      X Account shall terminate on the earlier of (i) the Class X Account Termination
      Date or (ii) the Distribution Date on which the amount on deposit in the Class
      X
      Account is reduced to zero.

     

    ARTICLE
      VI.


     

    CONCERNING
      THE TRUSTEE; EVENTS OF DEFAULT

     

    Section
      6.01. Duties
      of Trustee

     

    (a) The
      Trustee, except during the continuance of an Event of Default of which a
      Responsible Officer of the Trustee shall have actual knowledge, undertakes
      to
      perform such duties and only such duties as are specifically set forth in this
      Agreement. Any permissive right of the Trustee provided for in this Agreement
      shall not be construed as a duty of the Trustee. If an Event of Default (of
      which a Responsible Officer of the Trustee shall have actual knowledge) has
      occurred and has not otherwise been cured or waived, the Trustee shall exercise
      such of the rights and powers vested in it by this Agreement and use the same
      degree of care and skill in their exercise as a prudent Person would exercise
      or
      use under the circumstances in the conduct of such Person’s own affairs, unless
      the Trustee is acting as Master Servicer, in which case it shall use the same
      degree of care and skill as the Master Servicer hereunder.

     

    (b) The
      Trustee, upon receipt of all resolutions, certificates, statements, opinions,
      reports, documents, orders or other instruments furnished to the Trustee which
      are specifically required to be furnished pursuant to any provision of this
      Agreement, shall examine them to determine whether they are, on their face,
      in
      the form required by this Agreement; provided, however, that the Trustee shall
      not be responsible for the accuracy or content of any such resolution,
      certificate, statement, opinion, report, document, order or other instrument
      furnished by the Master Servicer, the Cap Provider or any Servicer to the
      Trustee pursuant to this Agreement, and shall not be required to recalculate
      or
      verify any numerical information furnished to the Trustee pursuant to this
      Agreement. Subject to the immediately preceding sentence, if any such
      resolution, certificate, statement, opinion, report, document, order or other
      instrument is found not to conform on its face to the form required by this
      Agreement in a material manner the Trustee shall notify the Person providing
      such resolutions, certificates, statements, opinions, reports or other documents
      of the non-conformity, and if the instrument is not corrected to the Trustee’s
      satisfaction, the Trustee will provide notice thereof to the Certificateholders
      and any NIMS Insurer and will, at the expense of the Trust Fund, which expense
      shall be reasonable given the scope and nature of the required action, take
      such
      further action as directed by the Certificateholders and any NIMS
      Insurer.

     

    (c) The
      Trustee shall not have any liability arising out of or in connection with this
      Agreement, except for its negligence or willful misconduct. Notwithstanding
      anything in this Agreement to the contrary, the Trustee shall not be liable
      for
      special, indirect or consequential losses or damages of any kind whatsoever
      (including, but not limited to, lost profits). No provision of this Agreement
      shall be construed to relieve the Trustee from liability for its own negligent
      action, its own negligent failure to act or its own willful misconduct;
      provided, however, that:

     

    (i) The
      Trustee shall not be personally liable with respect to any action taken,
      suffered or omitted to be taken by it in good faith in accordance with the
      consent or direction of the Holders of Certificates as provided in Section
      6.18
      hereof;

     

    
      
        
        

      

      
        -94-

        
          

        

      

      
        
        

      

    

     

    (ii) For
      all
      purposes under this Agreement, the Trustee shall not be deemed to have notice
      of
      any Event of Default (other than resulting from a failure by the Master Servicer
      to remit funds or to furnish information to the Trustee when required to do
      so)
      unless a Responsible Officer of the Trustee has actual knowledge thereof or
      unless written notice of any event which is in fact such a default is received
      by the Trustee at the address provided in Section 11.07, and such notice
      references the Holders of the Certificates and this Agreement; and

     

    (iii) The
      Trustee shall not be responsible for the acts or omissions of any Servicer,
      Custodian or the Master Servicer, it being understood that this Agreement shall
      not be construed to render any of them agents of one another.

     

    (d) The
      Trustee shall have no duty hereunder with respect to any complaint, claim,
      demand, notice or other document it may receive or which may be alleged to
      have
      been delivered to or served upon it by the parties as a consequence of the
      assignment of any Mortgage Loan hereunder; provided, however, that the Trustee
      shall promptly remit to the Master Servicer upon receipt any such complaint,
      claim, demand, notice or other document (i) which is delivered to the Corporate
      Trust Office of the Trustee and makes reference to this series of Certificate
      or
      this Agreement, (ii) of which a Responsible Officer has actual knowledge, and
      (iii) which contains information sufficient to permit the Trustee to make a
      determination that the real property to which such document relates is a
      Mortgaged Property.

     

    (e) The
      Trustee shall not be personally liable with respect to any action taken,
      suffered or omitted to be taken by it in good faith in accordance with the
      direction of any NIMS Insurer or the Certificateholders of any Class holding
      Certificates which evidence, as to such Class, Percentage Interests aggregating
      not less than 25% as to the time, method and place of conducting any proceeding
      for any remedy available to the Trustee or exercising any trust or power
      conferred upon the Trustee under this Agreement.

     

    (f) The
      Trustee shall not be required to perform services under this Agreement, or
      to
      expend or risk its own funds or otherwise incur financial liability for the
      performance of any of its duties hereunder or the exercise of any of its rights
      or powers if there is reasonable ground for believing that the timely payment
      of
      its fees and expenses or the repayment of such funds or adequate indemnity
      against such risk or liability is not reasonably assured to it, and none of
      the
      provisions contained in this Agreement shall in any event require the Trustee
      to
      perform, or be responsible for the manner of performance of, any of the
      obligations of the Master Servicer or any Servicer under this Agreement or
      any
      Servicing Agreement except during such time, if any, as the Trustee shall be
      the
      successor to, and be vested with the rights, duties, powers and privileges
      of,
      the Master Servicer in accordance with the terms of this Agreement, except
      with
      respect to the Trustee, during such time, if any, as the Trustee shall be the
      successor to, and be vested with the rights, duties, powers and privileges
      of,
      the Master Servicer in accordance with the terms of this Agreement.

     

    
      
        
        

      

      
        -95-

        
          

        

      

      
        
        

      

    

     

    (g) The
      Trustee shall not be held liable by reason of any insufficiency in any account
      (including without limitation the Collection Account and the Certificate
      Account) held by or on behalf of the Trustee resulting from any investment
      loss
      on any Eligible Investment included therein (except to the extent that the
      Trustee is the obligor and has defaulted thereon).

     

    (h) Except
      as
      otherwise provided herein, the Trustee shall not have any duty (A) to see to
      any
      recording, filing, or depositing of this Agreement or any agreement referred
      to
      herein or any financing statement or continuation statement evidencing a
      security interest, or to see to the maintenance of any such recording or filing
      or depositing or to any rerecording, refiling or redepositing of any thereof,
      (B) to see to any insurance, (C) to see to the payment or discharge of any
      tax,
      assessment, or other governmental charge or any lien or encumbrance of any
      kind
      owing with respect to, assessed or levied against, any part of the Trust Fund
      other than from funds available in the Collection Account or the Certificate
      Account, or (D) to confirm or verify the contents of any reports or certificates
      of the Master Servicer, any Servicer, the Cap Provider or the Depositor
      delivered to the Trustee pursuant to this Agreement believed by the Trustee
      to
      be genuine and to have been signed or presented by the proper party or
      parties.

     

    (i) The
      Trustee shall not be liable in its individual capacity for an error of judgment
      made in good faith by a Responsible Officer or other officers of the Trustee
      unless it shall be proved that the Trustee was negligent in ascertaining the
      pertinent facts.

     

    (j) Notwithstanding
      anything in this Agreement to the contrary, the Trustee shall not be liable
      for
      special, indirect or consequential losses or damages of any kind whatsoever
      (including, but not limited to, lost profits), even if the Trustee has been
      advised of the likelihood of such loss or damage and regardless of the form
      of
      action.

     

    (k) This
      Agreement shall not be construed to render the Trustee an agent of the Master
      Servicer or any Servicer.

     

    (l) For
      so
      long as the Depositor is subject to Exchange Act reporting requirements for
      the
      GreenPoint Mortgage Funding Trust Mortgage Pass-Through Certificates, Series
      2006-AR8 transaction, the Trustee shall give prior written notice to the
      Sponsor, the Master Servicer and the Depositor of the appointment of any
      Subcontractor by it and a written description (in form and substance
      satisfactory to the Sponsor and the Depositor) of the role and function of
      each
      Subcontractor utilized by the Trustee, specifying (A) the identity of each
      such
      Subcontractor and (B) which elements of the servicing criteria set forth under
      Item 1122(d) of Regulation AB will be addressed in assessments of compliance
      provided by each such Subcontractor.

     

    (m) The
      Trustee shall notify the Sponsor, the Master Servicer and the Depositor within
      five (5) calendar days of knowledge thereof (i) of any legal proceedings pending
      against the Trustee, of the type described in Item 1117 (§ 229.1117) of
      Regulation AB, (ii) of any merger, consolidation or sale of substantially all
      of
      the assets of the Trustee and (iii) if the Trustee shall become (but only to
      the
      extent not previously disclosed) at any time an affiliate of any of the parties
      listed on Exhibit S hereto or any of their affiliates. On or before March 1st
      of

    Section
      6.02. Certain
      Matters Affecting the Trustee

     

    Except
      as
      otherwise provided in Section 6.01:

     

    (i) The
      Trustee may request, and may rely upon and shall be protected in acting or
      refraining from acting upon any resolution, Officer’s Certificate, certificate
      of auditors or any other certificate, statement, instrument, opinion, report,
      notice, request, consent, order, approval, bond or other paper or document
      believed by it to be genuine and to have been signed or presented by the proper
      party or parties;

     

    (ii) The
      Trustee may consult with counsel and any advice of its counsel or Opinion of
      Counsel shall be full and complete authorization and protection in respect
      of
      any action taken or suffered or omitted by it hereunder in good faith and in
      accordance with such advice or Opinion of Counsel;

     

    (iii) The
      Trustee shall not be personally liable for any action taken, suffered or omitted
      by it in good faith and reasonably believed by it to be authorized or within
      the
      discretion or rights or powers conferred upon it by this Agreement;

     

    (iv) Unless
      an
      Event of Default shall have occurred and be continuing, the Trustee shall not
      be
      bound to make any investigation into the facts or matters stated in any
      resolution, certificate, statement, instrument, opinion, report, notice,
      request, consent, order, approval, bond or other paper or document (provided
      the
      same appears regular on its face), unless requested in writing to do so by
      any
      NIMS Insurer or the Holders of at least a majority in Class Principal Amount
      (or
      Percentage Interest) of each Class of Certificates; provided, however, that,
      if
      the payment within a reasonable time to the Trustee of the costs, expenses
      or
      liabilities likely to be incurred by it in the making of such investigation
      is,
      in the opinion of the Trustee not reasonably assured to the Trustee by the
      security afforded to it by the terms of this Agreement, the Trustee may require
      reasonable indemnity against such expense or liability or payment of such
      estimated expenses from any NIMS Insurer or the Certificateholders, as
      applicable, as a condition to proceeding. The reasonable expense thereof shall
      be paid by the party requesting such investigation and if not reimbursed by
      the
      requesting party shall be reimbursed to the Trustee by the Trust
      Fund;

     

    (v) The
      Trustee may execute any of the trusts or powers hereunder or perform any duties
      hereunder either directly or by or through agents, custodians or attorneys,
      which agents, custodians or attorneys shall have any and all of the rights,
      powers, duties and obligations of the Trustee conferred on them by such
      appointment, provided that the Trustee shall continue to be responsible for
      its
      duties and obligations hereunder to the extent provided herein, and provided
      further that the Trustee shall not be responsible for any misconduct or
      negligence on the part of any such agent or attorney appointed with due care
      by
      the Trustee;

     

    
      
        
        

      

      
        -97-

        
          

        

      

      
        
        

      

    

     

    (vi) The
      Trustee shall not be under any obligation to exercise any of the trusts or
      powers vested in it by this Agreement or to institute, conduct or defend any
      litigation hereunder or in relation hereto, in each case at the request, order
      or direction of any of the Certificateholders or any NIMS Insurer pursuant
      to
      the provisions of this Agreement, unless such Certificateholders or any NIMS
      Insurer shall have offered to the Trustee reasonable security or indemnity
      against the costs, expenses and liabilities which may be incurred therein or
      thereby;

     

    (vii) The
      right
      of the Trustee to perform any discretionary act enumerated in this Agreement
      shall not be construed as a duty, and the Trustee shall not be answerable for
      other than its negligence or willful misconduct in the performance of such
      act;
      and

     

    (viii) The
      Trustee shall not be required to give any bond or surety in respect of the
      execution of the Trust Fund created hereby or the powers granted
      hereunder.

     

    Section
      6.03. Trustee
      Not Liable for Certificates

     

    The
      Trustee makes no representations as to the validity or sufficiency of this
      Agreement, the Cap Agreements or of the Certificates (other than the certificate
      of authentication on the Certificates) or of any Mortgage Loan, or related
      document save that the Trustee represents that, assuming due execution and
      delivery by the other parties hereto, this Agreement has been duly authorized,
      executed and delivered by it and constitutes its valid and binding obligation,
      enforceable against it in accordance with its terms except that such
      enforceability may be subject to (A) applicable bankruptcy and insolvency laws
      and other similar laws affecting the enforcement of the rights of creditors
      generally, and (B) general principles of equity regardless of whether such
      enforcement is considered in a proceeding in equity or at law. The Trustee
      shall
      not be accountable for the use or application by the Depositor of funds paid
      to
      the Depositor in consideration of the assignment of the Mortgage Loans to the
      Trust Fund by the Depositor or for the use or application of any funds deposited
      into the Collection Account, the Certificate Account, any Escrow Account or
      any
      other fund or account maintained with respect to the Certificates. The Trustee
      shall not be responsible for the legality or validity of this Agreement or
      the
      Deferred Interest Cap Agreements or the validity, priority, perfection or
      sufficiency of the security for the Certificates issued or intended to be issued
      hereunder. Except as otherwise provided herein, the Trustee shall have no
      responsibility for filing any financing or continuation statement in any public
      office at any time or to otherwise perfect or maintain the perfection of any
      security interest or lien granted to it hereunder or to record this
      Agreement.

     

    Section
      6.04. Trustee
      May Own Certificates

     

    The
      Trustee and any Affiliate or agent of the Trustee in its individual or any
      other
      capacity may become the owner or pledgee of Certificates and may transact
      banking and trust business with the other parties hereto and their Affiliates
      with the same rights it would have if it were not Trustee or such
      agent.

     

    Section
      6.05. Eligibility
      Requirements for Trustee

     

    The
      Trustee hereunder shall at all times be (i) an institution whose accounts are
      insured by the FDIC, (ii) a corporation or national banking association,
      organized and doing business under the laws of any State or the United States
      of
      America, authorized under such laws to exercise corporate trust powers, having
      a
      combined capital and surplus of not less than $50,000,000 and subject to
      supervision or examination by federal or state authority and (iii) not an
      Affiliate of the Master Servicer or any Servicer. If such corporation or
      national banking association publishes reports of condition at least annually,
      pursuant to law or to the requirements of the aforesaid supervising or examining
      authority, then, for the purposes of this Section, the combined capital and
      surplus of such corporation or national banking association shall be deemed
      to
      be its combined capital and surplus as set forth in its most recent report
      of
      condition so published. In case at any time the Trustee shall cease to be
      eligible in accordance with provisions of this Section, the Trustee shall resign
      immediately in the manner and with the effect specified in Section
      6.06.

     

    
      
        
        

      

      
        -98-

        
          

        

      

      
        
        

      

    

     

    Section
      6.06. Resignation
      and Removal of Trustee

     

    (a) The
      Trustee may at any time resign and be discharged from the trust hereby created
      by giving written notice thereof to the Depositor, any NIMS Insurer and the
      Master Servicer. Upon receiving such notice of resignation, the Depositor will
      promptly appoint a successor trustee acceptable to any NIMS Insurer by written
      instrument, one copy of which instrument shall be delivered to the resigning
      Trustee, one copy to the successor trustee and one copy to each of the Master
      Servicer and any NIMS Insurer. If no successor trustee shall have been so
      appointed and shall have accepted appointment within 30 days after the giving
      of
      such notice of resignation, the resigning Trustee may petition any court of
      competent jurisdiction for the appointment of a successor trustee.

     

    (b) If
      at any
      time (i) the Trustee shall cease to be eligible in accordance with the
      provisions of Section 6.05 and shall fail to resign after written request
      therefor by the Depositor or any NIMS Insurer, (ii) the Trustee shall become
      incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver
      of the Trustee or of its property shall be appointed, or any public officer
      shall take charge or control of the Trustee or of its property or affairs for
      the purpose of rehabilitation, conservation or liquidation, (iii) a tax is
      imposed or threatened with respect to the Trust Fund by any state in which
      the
      Trustee or the Trust Fund held by the Trustee is located, (iv) the continued
      use
      of the Trustee would result in a downgrading of the rating by any Rating Agency
      of any Class of Certificates with a rating or (v) the Trustee shall fail to
      provide the information required pursuant to Section 6.01(l) or (m) or Section
      9.25 hereof, then the Depositor, any NIMS Insurer or the Master Servicer shall
      remove the Trustee and the Depositor shall appoint a successor trustee
      acceptable to any NIMS Insurer and the Master Servicer by written instrument,
      one copy of which instrument shall be delivered to each of the Trustee so
      removed, the successor trustee, the Master Servicer and any NIMS
      Insurer.

     

    (c) The
      Holders of more than 50% of the Class Principal Amount (or Percentage Interest)
      of each Class of Certificates (or any NIMS Insurer in the event of failure
      of
      the Trustee to perform its obligations hereunder) may at any time upon 30 days’
written notice to the Trustee and the Depositor remove the Trustee by such
      written instrument, signed by such Holders or their attorney in fact duly
      authorized (or by any NIMS Insurer), one copy of which instrument shall be
      delivered to each of the Depositor, the Trustee, the Master Servicer and any
      NIMS Insurer; and the Depositor shall thereupon appoint a successor trustee
      in
      accordance with this Section mutually acceptable to the Depositor, the Master
      Servicer and any NIMS Insurer.

     

    
      
        
        

      

      
        -99-

        
          

        

      

      
        
        

      

    

     

    (d) Any
      resignation or removal of the Trustee and appointment of a successor trustee
      pursuant to any of the provisions of this Section shall become effective upon
      (i) the payment of all unpaid amounts owed to the Trustee and (ii) the
      acceptance of appointment by the successor trustee as provided in Section
      6.07.

     

    Section
      6.07. Successor
      Trustee

     

    (a) Any
      successor trustee appointed as provided in Section 6.06 shall execute,
      acknowledge and deliver to the Depositor, the Master Servicer and any NIMS
      Insurer and to its predecessor trustee an instrument accepting such appointment
      hereunder, and thereupon the resignation or removal of the predecessor trustee
      shall become effective and such successor trustee without any further act,
      deed
      or conveyance, shall become fully vested with all the rights, powers, duties
      and
      obligations of its predecessor hereunder, with like effect as if originally
      named as trustee herein. The predecessor trustee (or its custodian) shall
      deliver to the successor trustee (or assign to the Trustee its interest under
      the Custodial Agreement, to the extent permitted thereunder) all Mortgage Files
      and documents and statements related to each Mortgage File held by it hereunder,
      and shall duly assign, transfer, deliver and pay over to the successor trustee
      the entire Trust Fund, together with all necessary instruments of transfer
      and
      assignment or other documents properly executed necessary to effect such
      transfer and such of the records or copies thereof maintained by the predecessor
      trustee in the administration hereof as may be requested by the successor
      trustee and shall thereupon be discharged from all duties and responsibilities
      under this Agreement. In addition, the Master Servicer and the predecessor
      trustee shall execute and deliver such other instruments and do such other
      things as may reasonably be required to more fully and certainly vest and
      confirm in the successor trustee all such rights, powers, duties and
      obligations.

     

    (b) No
      successor trustee shall accept appointment as provided in this Section unless
      at
      the time of such appointment such successor trustee shall be eligible under
      the
      provisions of Section 6.05.

     

    (c) Upon
      acceptance of appointment by a successor trustee as provided in this Section,
      the predecessor trustee shall mail notice of the succession of such trustee
      hereunder to all Holders of Certificates at their addresses as shown in the
      Certificate Register and to any Rating Agency. The expenses of such mailing
      shall be borne by the predecessor trustee.

     

    Section
      6.08. Merger
      or Consolidation of Trustee

     

    Any
      Person into which the Trustee may be merged or with which it may be
      consolidated, or any Person resulting from any merger, conversion or
      consolidation to which the Trustee shall be a party, or any Persons succeeding
      to the corporate trust business of the Trustee shall be the successor to the
      Trustee hereunder, without the execution or filing of any paper or any further
      act on the part of any of the parties hereto, anything herein to the contrary
      notwithstanding, provided that such Person shall be eligible under the
      provisions of Section 6.05. As
      a
      condition to the succession to the Trustee under this Agreement by any Person
      (i) into which the Trustee may be merged or consolidated, or (ii) which may
      be
      appointed as a successor to the Trustee, the Trustee shall notify the Depositor
      and the Master Servicer, at least 15 calendar days prior to the effective date
      of such succession or appointment, of such succession or appointment and shall
      furnish to the Depositor in writing and in form and substance reasonably
      satisfactory to the Depositor, all information reasonably necessary for the
      Trustee to accurately and timely report, pursuant to Section 6.20, the event
      under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports under
      the Exchange Act are required to be filed under the Exchange Act).

    Section
      6.09. Appointment
      of Co-Trustee, Separate Trustee or Custodian

     

    (a) Notwithstanding
      any other provisions hereof, at any time, the Trustee, the Depositor or the
      Certificateholders evidencing more than 50% of the Class Principal Amount (or
      Percentage Interest) of every Class of Certificates shall have the power from
      time to time to appoint one or more Persons, approved by the Trustee and any
      NIMS Insurer, to act either as co-trustees jointly with the Trustee, or as
      separate trustees, or as custodians, for the purpose of holding title to,
      foreclosing or otherwise taking action with respect to any Mortgage Loan outside
      the state where the Trustee has its principal place of business where such
      separate trustee or co-trustee is necessary or advisable (or the Trustee has
      been advised by the Master Servicer that such separate trustee or co-trustee
      is
      necessary or advisable) under the laws of any state in which a property securing
      a Mortgage Loan is located or for the purpose of otherwise conforming to any
      legal requirement, restriction or condition in any state in which a property
      securing a Mortgage Loan is located or in any state in which any portion of
      the
      Trust Fund is located. The separate Trustees, co-trustees, or custodians so
      appointed shall be trustees or custodians for the benefit of all the
      Certificateholders and shall have such powers, rights and remedies as shall
      be
      specified in the instrument of appointment; provided, however, that no such
      appointment shall, or shall be deemed to, constitute the appointee an agent
      of
      the Trustee. The obligation of the Trustee to make Advances pursuant to Section
      5.04 and 6.14 shall not be affected or assigned by the appointment of a
      co-trustee. Prior to the appointment hereunder of any co-trustee, separate
      trustee, or custodian pursuant to this Section 6.09, such Person shall enter
      into an agreement, in form and substance satisfactory to the Depositor, the
      Master Servicer and the Trustee, relating to the satisfaction of such Person
      of
      its reporting obligations under Regulation AB with respect to any servicing
      performed by it in connection with the Trust Fund. The Trustee shall not be
      responsible for any action or omission of any separate trustee, co-trustee
      or
      custodian. Notwithstanding the foregoing, if such co-custodian or co-trustee
      is
      determined to be a Servicing Function Participant, no such co-custodian or
      co-trustee shall be vested with any powers, rights and remedies under this
      Agreement unless such party has agreed to comply with all Regulation AB
      requirements set forth under this Agreement or the Custodial Agreement, as
      applicable.

     

    (b) Every
      separate trustee, co-trustee, and custodian shall, to the extent permitted
      by
      law, be appointed and act subject to the following provisions and
      conditions:

     

    (i) all
      powers, duties, obligations and rights conferred upon the Trustee in respect
      of
      the receipt, custody and payment of moneys shall be exercised solely by the
      Trustee;

     

    (ii) all
      other
      rights, powers, duties and obligations conferred or imposed upon the Trustee
      shall be conferred or imposed upon and exercised or performed by the Trustee
      and
      such separate trustee, co-trustee, or custodian jointly, except to the extent
      that under any law of any jurisdiction in which any particular act or acts
      are
      to be performed the Trustee shall be incompetent or unqualified to perform
      such
      act or acts, in which event such rights, powers, duties and obligations,
      including the holding of title to the Trust Fund or any portion thereof in
      any
      such jurisdiction, shall be exercised and performed by such separate trustee,
      co-trustee, or custodian;

    
       

      
        
          
          

        

        
          -101-

          
            

          

        

        
          
          

        

      

       

    

    (iii) no
      trustee or custodian hereunder shall be personally liable by reason of any
      act
      or omission of any other trustee or custodian hereunder; and

     

    (iv) the
      Trustee or the Certificateholders evidencing more than 50% of the Aggregate
      Voting Interests of the Certificates may at any time accept the resignation
      of
      or remove any separate trustee, co-trustee or custodian, so appointed by it
      or
      them, if such resignation or removal does not violate the other terms of this
      Agreement.

     

    (c) Any
      notice, request or other writing given to the Trustee shall be deemed to have
      been given to each of the then separate trustees and co-trustees, as effectively
      as if given to each of them. Every instrument appointing any separate trustee,
      co-trustee or custodian shall refer to this Agreement and the conditions of
      this
      Article VI. Each separate trustee and co-trustee, upon its acceptance of the
      trusts conferred, shall be vested with the estates or property specified in
      its
      instrument of appointment, either jointly with the Trustee or separately, as
      may
      be provided therein, subject to all the provisions of this Agreement,
      specifically including every provision of this Agreement relating to the conduct
      of, affecting the liability of, or affording protection to, the Trustee. Every
      such instrument shall be filed with the Trustee and a copy given to the Master
      Servicer and any NIMS Insurer.

     

    (d) Any
      separate trustee, co-trustee or custodian may, at any time, constitute the
      Trustee its agent or attorney in fact with full power and authority, to the
      extent not prohibited by law, to do any lawful act under or in respect of this
      Agreement on its behalf and in its name. If any separate trustee, co-trustee
      or
      custodian shall die, become incapable of acting, resign or be removed, all
      of
      its estates, properties, rights, remedies and trusts shall vest in and be
      exercised by the Trustee, to the extent permitted by law, without the
      appointment of a new or successor trustee.

     

    (e) No
      separate trustee, co-trustee or custodian hereunder shall be required to meet
      the terms of eligibility as a successor trustee under Section 6.05 hereunder
      and
      no notice to Certificateholders of the appointment shall be required under
      Section 6.07 hereof.

     

    (f) The
      Trustee agrees to instruct the co-trustees, if any, to the extent necessary
      to
      fulfill the Trustee’s obligations hereunder.

     

    (g) The
      Trustee shall pay the reasonable compensation of the co-trustees requested
      by
      the Trustee to be so appointed (which compensation shall not reduce any
      compensation payable to the Trustee) and, if paid by the Trustee, shall be
      a
      reimbursable expense pursuant to Section 6.12.

     

    (h) Notwithstanding
      the foregoing, for so long as reports are required to be filed with the
      Commission under the Exchange Act with respect to the Trust, the Trustee shall
      not utilize any Subcontractor for the performance of its duties hereunder if
      such Subcontractor would be “participating in the servicing function” within the
      meaning of Item 1122 of Regulation AB without (a) giving notice to the Seller,
      the Master Servicer and the Depositor and (b) requiring any such Subcontractor
      to provide to the Trustee an assessment of compliance as provided in Section
      9.25(a) and an attestation report as provided in Section 9.25(b), which reports
      the Trustee shall include in its assessment and attestation reports. The Trustee
      shall indemnify the Depositor and the Master Servicer and any director, officer,
      employee or agent of each of the Depositor and the Master Servicer and hold
      them
      harmless against any and all claims, losses, damages, penalties, fines,
      forfeitures, reasonable and necessary legal fees and related costs, judgments,
      and any other costs, fees and expenses that any of them may sustain arising
      out
      of or based upon the failure by the Trustee (i) to give notice of the engagement
      of any Subcontractor or (ii) to require any Subcontractor to provide the Trustee
      an assessment of compliance as provided in Section 9.25(a) and an attestation
      report as provided in Section 9.25(b). This indemnity shall survive the
      termination of this Agreement or the earlier resignation or removal of the
      Trustee.

    Section
      6.10. Authenticating
      Agents

     

    (a) The
      Trustee may appoint one or more Authenticating Agents which shall be authorized
      to act on behalf of the Trustee in authenticating Certificates. Wherever
      reference is made in this Agreement to the authentication of Certificates by
      the
      Trustee or the Trustee’s certificate of authentication, such reference shall be
      deemed to include authentication on behalf of the Trustee by an Authenticating
      Agent and a certificate of authentication executed on behalf of the Trustee
      by
      an Authenticating Agent. Each Authenticating Agent must be a corporation
      organized and doing business under the laws of the United States of America
      or
      of any state, having a combined capital and surplus of at least $15,000,000,
      authorized under such laws to do a trust business and subject to supervision
      or
      examination by federal or state authorities and acceptable to any NIMS
      Insurer.

     

    (b) Any
      Person into which any Authenticating Agent may be merged or converted or with
      which it may be consolidated, or any Person resulting from any merger,
      conversion or consolidation to which any Authenticating Agent shall be a party,
      or any Person succeeding to the corporate agency business of any Authenticating
      Agent, shall continue to be the Authenticating Agent without the execution
      or
      filing of any paper or any further act on the part of the Trustee or the
      Authenticating Agent.

     

    (c) Any
      Authenticating Agent may at any time resign by giving at least 30 days’ advance
      written notice of resignation to the Trustee, any NIMS Insurer and the
      Depositor. The Trustee may at any time terminate the agency of any
      Authenticating Agent by giving written notice of termination to such
      Authenticating Agent, any NIMS Insurer and the Depositor. Upon receiving a
      notice of resignation or upon such a termination, or in case at any time any
      Authenticating Agent shall cease to be eligible in accordance with the
      provisions of this Section 6.10, the Trustee may appoint a successor
      Authenticating Agent, shall give written notice of such appointment to the
      Depositor and any NIMS Insurer and shall mail notice of such appointment to
      all
      Holders of Certificates. Any successor Authenticating Agent upon acceptance
      of
      its appointment hereunder shall become vested with all the rights, powers,
      duties and responsibilities of its predecessor hereunder, with like effect
      as if
      originally named as Authenticating Agent. No successor Authenticating Agent
      shall be appointed unless eligible under the provisions of this Section 6.10.
      No
      Authenticating Agent shall have responsibility or liability for any action
      taken
      by it as such at the direction of the Trustee. Any Authenticating Agent shall
      be
      entitled to reasonable compensation for its services and, if paid by the
      Trustee, it shall be a reimbursable expense pursuant to Section
      6.12.

    Section
      6.11. Indemnification
      of Trustee

     

    The
      Trustee and its respective directors, officers, employees and agents shall
      be
      entitled to indemnification from the Trust Fund for any loss, liability or
      expense incurred in connection with any legal proceeding or incurred without
      negligence or willful misconduct on their part (it being understood that the
      negligence or willful misconduct of any Custodian shall not constitute
      negligence or willful misconduct on the part of the Trustee or its directors,
      officers, employees or agents for such purpose), arising out of, or in
      connection with, the acceptance or administration of the trusts created
      hereunder or in connection with the performance of their duties hereunder,
      the
      Mortgage Loan Sale Agreement, the Cap Agreements, any Transfer Agreement, any
      Servicing Agreement or any Custodial Agreement, including any applicable fees
      and expenses payable pursuant to Section 6.12 and the costs and expenses of
      defending themselves against any claim in connection with the exercise or
      performance of any of their powers or duties hereunder, provided
      that:

     

    (i) with
      respect to any such claim, the Trustee shall have given the Depositor, the
      Master Servicer and the Holders written notice thereof promptly after the
      Trustee shall have knowledge thereof; provided that failure to so notify shall
      not relieve the Trust Fund of the obligation to indemnify the Trustee; however,
      any reasonable delay by the Trustee to provide written notice to the Depositor,
      the Master Servicer and the Holders promptly after the Trustee shall have
      obtained knowledge of a claim shall not relieve the Trust Fund of the obligation
      to indemnify the Trustee under this Section 6.11;

     

    (ii) while
      maintaining control over its own defense, the Trustee shall cooperate and
      consult fully with the Depositor in preparing such defense; and

     

    (iii) notwithstanding
      anything to the contrary in this Section 6.11, the Trust Fund shall not be
      liable for settlement of any such claim by the Trustee entered into without
      the
      prior consent of the Depositor, which consent shall not be unreasonably
      withheld.

     

    The
      provisions of this Section 6.11 shall survive any termination of this Agreement
      and the resignation or removal of the Trustee and shall be construed to include,
      but not be limited to any loss, liability or expense under any environmental
      law.

     

    Section
      6.12. Fees
      and Expenses of Trustee and Custodian

     

    The
      Trustee shall be entitled to (i) receive, and is authorized to pay itself,
      the
      amount of income or gain earned from investment of funds in the Certificate
      Account and (ii) reimbursement of all reasonable expenses, disbursements and
      advances incurred or made by the Trustee in accordance with this Agreement
      (including fees and expenses of its counsel and all persons not regularly in
      its
      employment and any amounts described in Section 10.01 to which the Trustee
      is
      entitled as provided therein), except for expenses, disbursements and advances
      that either (i) do not constitute “unanticipated expenses” within the meaning of
      Treasury Regulations Section 1.860G-1(b)(3)(ii) or (ii) arise from its
      negligence, bad faith or willful misconduct. The Custodian shall receive
      compensation and reimbursement or payment of its expenses under the Custodial
      Agreement as provided therein; provided that, to the extent required under
      Section 6 or Section 20 of the Custodial Agreement, the Trustee is hereby
      authorized to pay such compensation or reimbursement from amounts on deposit
      in
      the Certificate Account prior to any distributions to Certificateholders
      pursuant to Section 5.02 hereof.

     

    
      
        
        

      

      
        -104-

        
          

        

      

      
        
        

      

    

     

    Section
      6.13. Collection
      of Monies

     

    Except
      as
      otherwise expressly provided in this Agreement, the Trustee may demand payment
      or delivery of, and shall receive and collect, all money and other property
      payable to or receivable by the Trustee pursuant to this Agreement. The Trustee
      shall hold all such money and property received by it as part of the Trust
      Fund
      and shall distribute it as provided in this Agreement. If the Trustee shall
      not
      have timely received amounts to be remitted with respect to the Mortgage Loans
      from the Master Servicer, the Trustee shall request the Master Servicer to
      make
      such distribution as promptly as practicable or legally permitted. If the
      Trustee shall subsequently receive any such amount, it may withdraw such
      request.

     

    Section
      6.14. Events
      of Default; Trustee To Act; Appointment of Successor

     

    (a) The
      occurrence of any one or more of the following events shall constitute an “Event
      of Default”:

     

    (i) Any
      failure by the Master Servicer to furnish to the Trustee the Mortgage Loan
      data
      sufficient to prepare the reports described in Section 4.03(a) which continues
      unremedied for a period of two (2) Business Days after the date upon which
      written notice of such failure shall have been given to such Master Servicer
      by
      the Trustee or to such Master Servicer and the Trustee by any NIMS Insurer
      or
      Holders of not less than 25% of the Class Principal Amount of each Class of
      Certificates affected thereby; or

     

    (ii) Any
      failure on the part of the Master Servicer duly to observe or perform in any
      material respect any other of the covenants or agreements on the part of the
      Master Servicer contained in this Agreement which continues unremedied for
      a
      period of 30 days (or 15 days, in the case of failure to maintain any Insurance
      Policy required to be maintained pursuant to this Agreement) after the date
      on
      which written notice of such failure, requiring the same to be remedied, shall
      have been given to the Master Servicer by the Trustee or to the Master Servicer
      and the Trustee by any NIMS Insurer or Holders of not less than 25% of the
      Class
      Principal Amount (or Class Notional Amount) of each Class of Certificates
      affected thereby or by any NIMS Insurer; or

     

    (iii) A
      decree
      or order of a court or agency or supervisory authority having jurisdiction
      for
      the appointment of a conservator or receiver or liquidator in any insolvency,
      readjustment of debt, marshalling of assets and liabilities or similar
      proceedings, or for the winding up or liquidation of its affairs, shall have
      been entered against the Master Servicer, and such decree or order shall have
      remained in force undischarged or unstayed for a period of 60 days or any Rating
      Agency reduces or withdraws or threatens to reduce or withdraw the rating of
      the
      Certificates because of the financial condition or loan servicing capability
      of
      such Master Servicer; or

     

    
      
        
        

      

      
        -105-

        
          

        

      

      
        
        

      

    

     

    (iv) The
      Master Servicer shall consent to the appointment of a conservator or receiver

      or

     

    (v) The
      Master Servicer shall admit in writing its inability to pay its debts generally
      as they become due, file a petition to take advantage of any applicable
      insolvency or reorganization statute, make an assignment for the benefit of
      its
      creditors or voluntarily suspend payment of its obligations; or

     

    (vi) The
      Master Servicer shall be dissolved, or shall dispose of all or substantially
      all
      of its assets, or consolidate with or merge into another entity or shall permit
      another entity to consolidate or merge into it, such that the resulting entity
      does not meet the criteria for a successor servicer as specified in Section
      9.27
      hereof; or

     

    (vii) If
      a
      representation or warranty set forth in Section 9.14 hereof shall prove to
      be
      incorrect as of the time made in any respect that materially and adversely
      affects the interests of the Certificateholders, and the circumstance or
      condition in respect of which such representation or warranty was incorrect
      shall not have been eliminated or cured within 30 days after the date on which
      written notice of such incorrect representation or warranty shall have been
      given to the Master Servicer by the Trustee or to the Master Servicer and the
      Trustee by the Holders of more than 50% of the Aggregate Voting Interests of

      NIMS Insurer and Certificateholders holding more than 50% of the Aggregate
      Voting Interests of the Certificates; or

     

    (ix) The
      Master Servicer has notice or actual knowledge that a Servicer at any time
      is
      not either a Fannie Mae- or Freddie Mac- approved Seller/Servicer, and the
      Master Servicer has not terminated the rights and obligations of such Servicer
      under the Servicing Agreement and replaced such Servicer with a Fannie Mae-
      or
      Freddie Mac-approved servicer within 60 days of the date the Master Servicer
      receives such notice or acquires such actual knowledge; or

     

    (x) After
      any
      receipt of notice from the Trustee or any NIMS Insurer, any failure of the
      Master Servicer to remit to the Trustee any payment required to be made to
      the
      Trustee for the benefit of Certificateholders under the terms of this Agreement,
      including any Advance, on any Deposit Date, which failure continues unremedied
      for a period of one Business Day after the date upon which such written notice
      of such failure shall have been given to the Master Servicer by the
      Trustee.

     

    
      
        
        

      

      
        -106-

        
          

        

      

      
        
        

      

    

     

    If
      an
      Event of Default described in clauses (i) through (ix) of this Section 6.14
      shall occur, then, in each and every case, subject to applicable law, so long
      as
      any such Event of Default shall not have been remedied within any period of
      time
      prescribed by this Section, the Trustee, by notice in writing to the Master
      Servicer may, and shall, if so directed by Certificateholders evidencing more
      than 50% of the Class Principal Amount (or Class Notional Amount) of each Class
      of Certificates or any NIMS Insurer, terminate all of the rights and obligations
      of the Master Servicer hereunder and in and to the Mortgage Loans and the
      proceeds thereof. If an Event of Default described in clause (x) of this Section
      6.14 shall occur, then, in each and every case, subject to applicable law,
      so
      long as such Event of Default shall not have been remedied within the time
      period prescribed by clause (x) of this Section 6.14, the Trustee, by notice
      in
      writing to the Master Servicer and the NIMS Insurer, shall promptly terminate
      all the rights and obligations of the Master Servicer hereunder and in and
      to
      the Mortgage Loans and the proceeds thereof. On or after the receipt by the
      Master Servicer of such written notice, all authority and power of the Master
      Servicer, and only in its capacity as Master Servicer under this Agreement,
      whether with respect to the Mortgage Loans or otherwise, shall pass to and
      be
      vested in the Trustee and pursuant to and under the terms of this Agreement;
      provided, however, the parties acknowledge that notwithstanding the preceding
      sentence, there may be a transition period, not to exceed 90 days, in order
      to
      effect the transfer of the Master Servicer’s obligations to the Trustee, the
      Trustee is hereby authorized and empowered to execute and deliver, on behalf
      of
      the defaulting Master Servicer as attorney-in-fact or otherwise, any and all
      documents and other instruments, and to do or accomplish all other acts or
      things necessary or appropriate to effect the purposes of such notice of
      termination, whether to complete the transfer and endorsement or assignment
      of
      the Mortgage Loans and related documents or otherwise. The defaulting Master
      Servicer agrees to cooperate with the Trustee in effecting the termination
      of
      the defaulting Master Servicer’s responsibilities and rights hereunder as Master
      Servicer including, without limitation, notifying the Servicers of the
      assignment of the master servicing function and providing the Trustee or its
      designee all documents and records in electronic or other form reasonably
      requested by it to enable the Trustee or its designee to assume the defaulting
      Master Servicer’s functions hereunder and the transfer to the Trustee for
      administration by it of all amounts which shall at the time be or should have
      been deposited by the defaulting Master Servicer in the Collection Account
      maintained by such defaulting Master Servicer and any other account or fund
      maintained with respect to the Certificates or thereafter received with respect
      to the Mortgage Loans. The Master Servicer being terminated (or the Trust Fund,
      if the Master Servicer is unable to fulfill its obligations hereunder) as a
      result of an Event of Default shall bear all costs of a master servicing
      transfer, including but not limited to those of the Trustee reasonably allocable
      to specific employees and overhead, legal fees and expenses, accounting and
      financial consulting fees and expenses, and costs of amending the Agreement,
      if
      necessary.

     

    The
      Trustee shall be entitled to be reimbursed from the Master Servicer (or by
      the
      Trust Fund, if the Master Servicer is unable to fulfill its obligations
      hereunder) for all costs associated with the transfer of master servicing from
      the predecessor Master Servicer, including, without limitation, any costs or
      expenses associated with the complete transfer of all master servicing data
      and
      the completion, correction or manipulation of such servicing data as may be
      required by the Trustee to correct any errors or insufficiencies in the master
      servicing data or otherwise to enable the Trustee to master service the Mortgage
      Loans properly and effectively. If the terminated Master Servicer does not
      pay
      such reimbursement within thirty (30) days of its receipt of an invoice
      therefor, such reimbursement shall be an expense of the Trust Fund and the
      Trustee shall be entitled to withdraw such reimbursement from amounts on deposit
      in the Certificate Account pursuant to Section 4.04(b); provided that the
      terminated Master Servicer shall reimburse the Trust Fund for any such expense
      incurred by the Trust Fund.

     

    
      
        
        

      

      
        -107-

        
          

        

      

      
        
        

      

    

     

    Notwithstanding
      the termination of its activities as Master Servicer, each terminated Master
      Servicer shall continue to be entitled to reimbursement to the extent provided
      in Section 4.02(a)(i), (ii), (iii), (v), (vii) and (ix) to the extent such
      reimbursement relates to the period prior to such Master Servicer’s
      termination.

     

    If
      any
      Event of Default shall occur of which a Responsible Officer of the Trustee
      has
      actual knowledge, the Trustee, shall promptly notify any NIMS Insurer and each
      Rating Agency of the nature and extent of such Event of Default. The Trustee
      shall immediately give written notice to the Master Servicer upon the Master
      Servicer’s failure to remit funds on the Deposit Date.

     

    (b) On
      or
      after the time the Master Servicer (and the Trustee, if notice is sent by any
      NIMS Insurer) receives a notice of termination from the Trustee pursuant to
      Section 6.14(a) or the Trustee receives the resignation of the Master Servicer
      evidenced by an Opinion of Counsel pursuant to Section 9.28, the Trustee, within
      90 days of such notice unless another master servicer acceptable to the NIMS
      Insurer shall have been appointed, shall be the successor in all respects to
      the
      Master Servicer in its capacity as such under this Agreement and the
      transactions set forth or provided for herein and shall have all the rights
      and
      powers and be subject to all the responsibilities, duties and liabilities
      relating thereto and arising thereafter placed on the Master Servicer hereunder,
      including the obligation to make Advances; provided, however, that any failure
      to perform such duties or responsibilities caused by the Master Servicer’s
      failure to provide information required by this Agreement shall not be
      considered a default by the Trustee hereunder. In addition, the Trustee shall
      have no responsibility for any act or omission of the Master Servicer prior
      to
      the issuance of any notice of termination. The Trustee shall have no liability
      relating to the representations and warranties of the Master Servicer set forth
      in Section 9.14. In the Trustee’s capacity as such successor, the Trustee shall
      have the same limitations on liability herein granted to the Master Servicer.
      As
      compensation therefor, the Trustee shall be entitled to receive all compensation
      payable to the Master Servicer under this Agreement, including the Master
      Servicing Fee. The Trustee shall be entitled to be reimbursed from the Master
      Servicer (or by the Trust Fund if the Master Servicer is unable to fulfill
      its
      obligations hereunder) for all costs associated with the transfer of master
      servicing from the predecessor master servicer, including, without limitation,
      any costs or expenses associated with the complete transfer of all master
      servicing data and the completion, correction or manipulation of such master
      servicing data as may be required by the Trustee to correct any errors or
      insufficiencies in the master servicing data or otherwise to enable the Trustee
      to master service the Mortgage Loans properly and effectively.

     

    
      
        
        

      

      
        -108-

        
          

        

      

      
        
        

      

    

     

    (c) Notwithstanding
      the above, the Trustee may, if it shall be unwilling to continue to so act,
      or
      shall, if it is unable to so act or if any NIMS Insurer so requests in writing
      to the Trustee, request the Depositor to appoint, petition a court of competent
      jurisdiction to appoint, or appoint on its own behalf any established housing
      and home finance institution servicer, master servicer, servicing or mortgage
      servicing institution acceptable to the NIMS Insurer having a net worth of
      not
      less than $15,000,000 and meeting such other standards for a successor master
      servicer as are set forth in this Agreement, as the successor to such Master
      Servicer in the assumption of all of the responsibilities, duties or liabilities
      of a master servicer, like the Master Servicer hereunder. Any entity designated
      by the Trustee as a successor master servicer may be an Affiliate of the
      Trustee; provided, however, that, unless such Affiliate meets the net worth
      requirements and other standards set forth herein for a successor master
      servicer, the Trustee in its individual capacity shall agree, at the time of
      such designation, to be and remain liable to the Trust Fund for such Affiliate’s
      actions and omissions in performing its duties hereunder. In connection with
      such appointment and assumption, the Trustee may make such arrangements for
      the
      compensation of such successor out of payments on Mortgage Loans as it and
      such
      successor shall agree; provided, however, that no such compensation shall be
      in
      excess of that permitted to the Master Servicer hereunder. The Trustee and
      such
      successor shall take such actions, consistent with this Agreement, as shall
      be
      necessary to effectuate any such succession and may make other arrangements
      with
      respect to the servicing to be conducted hereunder which are not inconsistent
      herewith. The Master Servicer shall cooperate with the Trustee and any successor
      master servicer in effecting the termination of the Master Servicer’s
      responsibilities and rights hereunder including, without limitation, notifying
      Mortgagors of the assignment of the master servicing functions and providing
      the
      Trustee and successor master servicer, as applicable, all documents and records
      in electronic or other form reasonably requested by it to enable it to assume
      the Master Servicer’s functions hereunder and the transfer to the Trustee or
      such successor master servicer, as applicable, all amounts which shall at the
      time be or should have been deposited by the Master Servicer in the Collection
      Account and any other account or fund maintained with respect to the
      Certificates or thereafter be received with respect to the Mortgage Loans.
      Neither the Trustee nor any other successor master servicer shall be deemed
      to
      be in default hereunder by reason of any failure to make, or any delay in
      making, any distribution hereunder or any portion thereof caused by (i) the
      failure of the Master Servicer to deliver, or any delay in delivering, cash,
      documents or records to it, (ii) the failure of the Master Servicer to cooperate
      as required by this Agreement, (iii) the failure of the Master Servicer to
      deliver the Mortgage Loan data to the Trustee or such successor master servicer
      as required by this Agreement or (iv) restrictions imposed by any regulatory
      authority having jurisdiction over the Master Servicer. No successor master
      servicer shall be deemed to be in default hereunder by reason of any failure
      to
      make, or any delay in making, any distribution hereunder or any portion thereof
      caused by (i) the failure of the terminated Master Servicer to deliver, or
      any
      delay in delivering cash, documents or records to it, or (ii) the failure of
      the
      terminated Master Servicer to cooperate as required by this
      Agreement.

     

    Section
      6.15. Additional
      Remedies of Trustee Upon Event of Default

     

    During
      the continuance of any Event of Default, so long as such Event of Default shall
      not have been remedied, the Trustee, in addition to the rights specified in
      Section 6.14, shall have the right, in its own name and as trustee of an express
      trust, to take all actions now or hereafter existing at law, in equity or by
      statute to enforce its rights and remedies and to protect the interests, and
      enforce the rights and remedies, of any NIMS Insurer and the Certificateholders
      (including the institution and prosecution of all judicial, administrative
      and
      other proceedings and the filings of proofs of claim and debt in connection
      therewith). Except as otherwise expressly provided in this Agreement, no remedy
      provided for by this Agreement shall be exclusive of any other remedy, and
      each
      and every remedy shall be cumulative and in addition to any other remedy, and
      no
      delay or omission to exercise any right or remedy shall impair any such right
      or
      remedy or shall be deemed to be a waiver of any Event of Default.

    Section
      6.16. Waiver
      of Defaults

     

    More
      than
      50% of the Aggregate Voting Interests of Certificateholders (with the consent
      of
      any NIMS Insurer) may waive any default or Event of Default by the Master
      Servicer in the performance of its obligations hereunder, except that a default
      in the making of any required deposit to the Certificate Account that would
      result in a failure of the Trustee to make any required payment of principal
      of
      or interest on the Certificates may only be waived with the consent of 100%
      of
      the affected Certificateholders and with the consent of any NIMS Insurer. Upon
      any such waiver of a past default, such default shall cease to exist, and any
      Event of Default arising therefrom shall be deemed to have been remedied for
      every purpose of this Agreement. No such waiver shall extend to any subsequent
      or other default or impair any right consequent thereon except to the extent
      expressly so waived.

     

    Section
      6.17. Notification
      to Holders

     

    Upon
      termination of the Master Servicer or appointment of a successor to the Master
      Servicer, in each case as provided herein, the Trustee shall promptly mail
      notice thereof by first class mail to the Certificateholders at their respective
      addresses appearing on the Certificate Register and any NIMS Insurer. The
      Trustee shall also, within 45 days after the occurrence of any Event of Default
      known to a Responsible Officer of the Trustee, give written notice thereof
      to
      any NIMS Insurer and the Certificateholders, unless such Event of Default shall
      have been cured or waived prior to the issuance of such notice and within such
      45 day period.

     

    Section
      6.18. Directions
      by Certificateholders and Duties of Trustee During Event of
      Default

     

    Subject
      to the provisions of Section 8.01 hereof, during the continuance of any Event
      of
      Default, Holders of Certificates evidencing not less than 25% of the Class
      Principal Amount (or Percentage Interest) of each Class of Certificates affected
      thereby may, with the consent of any NIMS Insurer, direct the time, method
      and
      place of conducting any proceeding for any remedy available to the Trustee,
      or
      exercising any trust or power conferred upon the Trustee, under this Agreement;
      provided, however, that the Trustee shall be under no obligation to pursue
      any
      such remedy, or to exercise any of the trusts or powers vested in it by this
      Agreement (including, without limitation, (i) the conducting or defending of
      any
      administrative action or litigation hereunder or in relation hereto and (ii)
      the
      terminating of the Master Servicer or any successor master servicer from its
      rights and duties as master servicer hereunder) at the request, order or
      direction of any of the Certificateholders, or any NIMS Insurer, unless such
      Certificateholders, or any NIMS Insurer, shall have offered to the Trustee
      reasonable security or indemnity against the cost, expenses and liabilities
      which may be incurred therein or thereby; and, provided further, that, subject
      to the provisions of Section 8.01, the Trustee shall have the right to decline
      to follow any such direction if the Trustee, in accordance with an Opinion
      of
      Counsel, determines that the action or proceeding so directed may not lawfully
      be taken or if the Trustee in good faith determines that the action or
      proceeding so directed would involve it in personal liability for which it
      is
      not indemnified to its satisfaction or be unjustly prejudicial to the non
      assenting Certificateholders.

    Section
      6.19. Action
      Upon Certain Failures of the Master Servicer and Upon Event of
      Default

     

    In
      the
      event that a Responsible Officer of the Trustee shall have actual knowledge
      of
      any action or inaction of the Master Servicer that would become an Event of
      Default upon the Master Servicer’s failure to remedy the same after notice, the
      Trustee shall give notice thereof to the Master Servicer. For all purposes
      of
      this Agreement, in the absence of actual knowledge by a Responsible Officer
      of
      the Trustee, the Trustee shall not be deemed to have knowledge of any failure
      of
      the Master Servicer or any other Event of Default unless notified in writing
      by
      the Depositor, the Master Servicer or the Certificateholders.

      based
      upon information calculated in accordance with this Agreement pursuant to
      instructions given by the Depositor, and the Trustee shall file federal tax
      returns, all in accordance with Article X hereof. The Trustee shall prepare
      and
      file required state income tax returns and such other returns as may be required
      by applicable law relating to the Trust Fund, and, if required by state law,
      and
      shall file any other documents to the extent required by applicable state tax
      law (to the extent such documents are in the Trustee’s possession). The Trustee
      shall forward copies to the Depositor of all such returns and Form 1099
      supplemental tax information and such other information within the control
      of
      the Trustee as the Depositor may reasonably request in writing, and shall
      distribute to each Certificateholder such forms and furnish such information
      within the control of the Trustee as are required by the Code and the REMIC
      Provisions to be furnished to them, and will prepare and distribute to
      Certificateholders Form 1099 (supplemental tax information) (or otherwise
      furnish information within the control of the Trustee) to the extent required
      by
      applicable law. The Master Servicer shall indemnify the Trustee for any
      liability of or assessment against the Trustee arising out of or based upon
      any
      error in any of such tax or information returns arising out of or based upon
      errors in the information provided by such Master Servicer.

     

    (b) The
      Trustee shall prepare and file with the IRS, on behalf of each REMIC created
      hereby, an application on IRS Form SS-4. The Trustee, upon receipt from the
      IRS
      of the Notice of Taxpayer Identification Number Assigned for each REMIC, shall
      promptly forward copies of such notices to the Master Servicer and the
      Depositor. The Trustee will file an IRS Form 8811 for all REMICs created
      hereunder. The Trustee shall have no obligation to verify the information in
      any
      Form 8811 or Form SS-4 filing.

      as
      set forth in the next paragraph.

     

    (ii) As
      set
      forth on Exhibit Q-1 hereto, within five calendar days after the related

      inclusion of the Additional Form 10-D Disclosure on Form 10-D. The Sponsor
      will
      be responsible for any reasonable fees and expenses assessed or incurred by
      the
      Trustee in connection with including any Additional Form 10-D Disclosure on
      Form
      10-D pursuant to this paragraph.

     

    (iii) After
      preparing the Form 10-D, the Trustee shall forward electronically a draft copy
      of the Form 10-D to the Exchange Act Signing Party for review and approval.
      If
      the Master Servicer is the Exchange Act Signing Party and the Form 10-D includes
      Additional Form 10-D Disclosure, then the Form 10-D shall also be electronically
      distributed to the Depositor for review and approval. No later than two Business
      Days prior to the 15th calendar day after the related Distribution Date, a
      senior officer of the Exchange Act Signing Party shall sign the Form 10-D and
      return an electronic or fax copy of such signed Form 10-D (with an original
      executed hard copy to follow by overnight mail) to the Trustee. If a Form 10-D
      cannot be filed on time or if a previously filed Form 10-D needs to be amended,
      the Trustee will follow the procedures set forth in subsection (f)(ii) of this
      Section 6.20. Promptly (but no later than one Business Day) after the deadline
      for filing such report with the Commission, the Trustee will make available
      on
      its internet website a final executed copy of each Form 10-D. Each party to
      this
      Agreement acknowledges that the performance by the Trustee of its duties under
      this Section 6.20(c) related to the timely preparation and filing of Form 10-D
      is contingent upon such parties strictly observing all applicable deadlines
      in
      the performance of their duties under this Section 6.20(c). The Trustee shall
      have no liability for any loss, expense, damage, claim arising out of or with
      respect to any failure to properly prepare and/or timely file such Form 10-D,
      where such failure results from the Trustee’s inability or failure to obtain or
      receive, on a timely basis, any information from any other party hereto needed
      to prepare, arrange for execution or file such Form 10-D, not resulting from
      its
      own negligence, bad faith or willful misconduct.

      loss, expense, damage, claim arising out of or with respect to any failure

      any information from any other party hereto needed to prepare, arrange for
      execution or file such Form 10-K, not resulting from its own negligence, bad

    (iii) After
      preparing the Form 8-K, the Trustee shall forward electronically, no later
      than
      Noon New York city time on the 3rd Business Day after the Reportable Event,
      a
      draft copy of the Form 8-K to the Exchange Act Signing Party for review and
      approval. If the Master Servicer is the Exchange Act Signing Party, then the
      Form 8-K shall also be electronically distributed to the Depositor for review
      and approval. No later than Noon New York City time on the 4th Business Day
      after the Reportable Event, a senior officer of the Exchange Act Signing Party

      8-K
      needs to be amended, the Trustee will follow the procedures set forth in
      subsection (f) of this Section 6.20. Promptly (but no later than one Business
      Day) after the deadline for filing such form with the Commission, the Trustee
      will, make available on its internet website a final executed copy of each

      Trustee of its duties under this Section 6.20(e) related to the timely
      preparation and filing of Form 8-K is contingent upon such parties strictly
      observing all applicable deadlines in the performance of their duties under
      this
      Section 6.20(e). The Trustee shall have no liability for any loss, expense,
      damage or claim arising out of or with respect to any failure to properly
      prepare and/or timely file such Form 8-K, where such failure results from the
      Trustee’s inability or failure to obtain or receive, on a timely basis, any
      information from any other party hereto needed to prepare, arrange for execution
      or file such Form 8-K, not resulting from its own negligence, bad faith or
      willful misconduct.

     

    (f) Delisting;
      Amendments; Late Filings.

     

    (i) Prior
      to
      January 30 of the first year in which the Trustee is able to do so under
      applicable law, unless otherwise directed by the Depositor, the Trustee shall
      prepare and file a Form 15 relating to the automatic suspension of reporting
      in
      respect of the Trust Fund under the Exchange Act.

     

    (ii) In
      the
      event that the Trustee becomes aware that it will be unable to timely file
      with
      the Commission all or any required portion of any Form 8-K, 10-D or 10-K
      required to be filed by this Agreement because required disclosure information
      was either not delivered to it or delivered to it after the delivery deadlines
      set forth in this Agreement or for any other reason, the Trustee will
      immediately notify the Depositor. In the case of Form 10-D and 10-K, the parties
      to this Agreement and the Servicer will cooperate to prepare and file a Form
      12b-25 and a 10-D/A and 10-K/A as applicable, pursuant to Rule 12b-25 of the
      Exchange Act. In the case of Form 8-K, the Trustee will, upon receipt of all
      required Form 8-K Disclosure Information and upon the approval and direction
      of
      the Depositor, include such disclosure information on the next Form 10-D. In
      the
      event that any previously filed Form 8-K, 10-D or 10-K needs to be amended,
      the
      Trustee will notify the Depositor and the Servicer and such parties will
      cooperate to prepare any necessary 8-K/A, 10-D/A or 10-K/A. Any Form 15, Form
      12b-25 or any amendment to Form 8-K, 10-D or 10-K shall be signed by a senior
      officer of the Exchange Act Signing Party. The parties to this Agreement
      acknowledge that the performance by the Trustee of its duties under this Section
      6.20(f) related to the timely preparation and filing of Form 15, a Form 12b-25
      or any amendment to Form 8-K, 10-D or 10-K is contingent upon each such party
      performing its duties under this Section. The Trustee shall have no liability
      for any loss, expense, damage, claim arising out of or with respect to any
      failure to properly prepare and/or timely file any such Form 15, Form 12b-25
      or
      any amendments to Forms 8-K, 10-D or 10-K, where such failure results from
      the
      Trustee’s inability or failure to obtain or receive, on a timely basis, any
      information from any other party hereto needed to prepare, arrange for execution
      or file such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K,
      not resulting from its own negligence, bad faith or willful
      misconduct.

    (g) Any
      party
      that signs any Exchange Act report that the Trustee is required to file shall
      provide to the Trustee prompt notice of the execution of such Exchange Act
      report along with the name and contact information for the person signing such
      report and shall promptly deliver to the Trustee the original executed signature
      page for such report. In addition, each of the parties agrees to provide to
      the
      Trustee such additional information related to such party as the Trustee may
      reasonably request, including evidence of the authorization of the person
      signing any certification or statement, financial information and reports,
      and
      such other information related to such party or its performance
      hereunder.

     

    (h) The
      Depositor and the Master Servicer, by mutual agreement, shall determine which
      of
      the Depositor or the Master Servicer shall be the initial Exchange Act Signing
      Party. Upon such determination, the Depositor shall timely notify the Trustee,
      and such notice shall provide contact information for the Exchange Act Signing
      Party. If the Depositor and Master Servicer, at any time, mutually agree to
      change the identity of the Exchange Act Signing Party, the Depositor shall
      provide timely notice to the Trustee of any such change.

     

    (i) The
      Trustee shall promptly send copies of each periodic report filed on Form 8-K,
      Form 10-D or other applicable form, each annual report on Form 10-K, and each

    TERMINATION
      OF THE TRUST FUND

     

    Section
      7.01. Purchase
      of Mortgage Loans; Termination of the Trust Fund Upon Purchase or Liquidation
      of
      Mortgage Loans

     

    (a) The
      respective obligations and responsibilities of the Trustee and the Master
      Servicer created hereby (other than the obligation of the Trustee to make
      payments to Certificateholders as set forth in Section 7.02, the obligation
      of
      the Master Servicer to make a final remittance to the Trustee pursuant to
      Section 4.01, and the obligations of the Master Servicer to the Trustee pursuant
      to Sections 9.10 and 9.14) shall terminate on the earliest of (i) the final
      payment or other liquidation of the last Mortgage Loan remaining in the Trust
      Fund and the disposition of all REO Property, (ii) the sale of the property
      held
      by the Trust Fund in accordance with Section 7.01(b) and (iii) the Latest
      Possible Maturity Date; provided, however, that in no event shall the Trust
      Fund
      created hereby continue beyond the expiration of 21 years from the death of
      the
      last survivor of the descendants of Joseph P. Kennedy, the late Ambassador
      of
      the United States to the Court of St. James’s, living on the date hereof. Any
      termination of the Trust Fund shall be carried out in such a manner so that
      the
      termination of each REMIC included therein shall qualify as a “qualified
      liquidation” under the REMIC Provisions.

    (b) On
      any
      Distribution Date occurring on or after the Initial Optional Termination Date,
      the Master Servicer, with the prior written consent of any NIMS Insurer and
      the
      Seller, which consent shall not be unreasonably withheld, has the option to
      cause each of REMIC 1 and REMIC 2 to adopt a plan of complete liquidation and
      to
      purchase the Mortgage Loans and any REO Property related to the Mortgage Pool
      (the “Pool Assets”) for a price equal to the Repurchase Price, pursuant to
      Section 7.03 hereof. Upon exercise of such option, the property of the Mortgage
      Pool shall be sold to the Master Servicer at a price (the “Repurchase Price”)
      equal to the sum of (i) 100% of the unpaid principal balance of each Mortgage
      Loan on the day of such purchase plus interest accrued thereon at the Mortgage
      Rate with respect to such Mortgage Loan to the Due Date in the Collection Period
      immediately preceding the Distribution Date on which the proceeds of such sale
      will be distributed to the holders of the Certificates, (ii) the fair market
      value of any REO Property related to the Mortgage Loans and any other property
      related to the Mortgage Loans held by any REMIC, such fair market value to
      be
      determined by an independent appraiser or appraisers mutually agreed upon by
      the
      Master Servicer, any NIMS Insurer and the Trustee (reduced, in the case of
      REO
      Property, by (1) reasonably anticipated disposition costs and (2) any amount
      by
      which the fair market value as so reduced exceeds the outstanding principal
      balance of the related Mortgage Loan plus interest accrued thereon at the
      applicable Net Mortgage Rate to the date of such purchase), (iii) any
      unreimbursed Servicing Advances and other amounts to be reimbursed pursuant
      to
      the immediately following sentence related to the Mortgage Loans and (iv) any
      Cap Termination Payment payable to the Cap Provider as a result of a termination
      pursuant to this Section 7.01; provided, however, if there are any NIM
      Securities outstanding, the Master Servicer may only exercise its option after
      receiving the prior written consent of the holders of such NIM Securities and,
      if such consent is given, the Repurchase Price shall also include an amount
      equal to the sum of (1) any accrued interest on the NIM Securities related
      to
      the Mortgage Loans, (2) the unpaid principal balance of any such NIM Securities
      and (3) any other reimbursable expenses owed by the issuer of the NIM Securities
      (the “NIM Redemption Amount”). The Master Servicer, the Servicer, the Trustee
      and the Custodian shall be reimbursed from the Repurchase Price for any Mortgage
      Loan or related REO Property for any Advances made or other amounts advanced
      with respect to the Mortgage Loans that are reimbursable to any such entity
      under this Agreement, the related Servicing Agreement or the Custodial
      Agreement, together with any accrued and unpaid compensation and any other
      amounts due to the Master Servicer or the Trustee hereunder or the applicable
      Servicer or the Custodian, to the extent such amounts relate to the Mortgage
      Loans. If the Master Servicer fails to exercise such right, the NIMS Insurer
      will have the option to direct the Master Servicer to exercise such option
      so
      long as it is insuring the NIM Securities or it is owed any amounts in
      connection with its guaranty of the NIM Securities. Following receipt of such
      notice from the NIMS Insurer, the Master Servicer shall advise the NIMS Insurer
      whether it will exercise the option under this Section 7.01(b) for its own
      account and using its own funds, or whether it will exercise such option in
      its
      own name but for the NIMS Insurer's account and utilizing the NIMS Insurer's
      funds. If the Master Servicer exercises such option for the NIMS Insurer's
      account, the NIMS Insurer will remit the Repurchase Price to the Master Servicer
      one Business Day prior to the day the Master Servicer is required to remit
      the
      Repurchase Price to the Trustee. Following its receipt from the NIMS Insurer
      of
      the entire Repurchase Price and its subsequent remittance to the Trustee of
      the
      entire Repurchase Price, the Master Servicer will convey to the NIMS Insurer
      all
      of the rights it receives from the Trustee with respect to the related Mortgage
      Loans as a result of such remittance. Subject to Section 7.03, the Trustee
      shall
      distribute the assets of the Trust Fund on the Distribution Date on which the
      repurchase occurred. If the NIMS Insurer directs the Master Servicer to exercise
      such right as described above, then (i) the Master Servicer shall cause each
      REMIC to adopt a plan of complete liquidation as described above and (ii) the
      NIMS Insurer shall remit the Repurchase Price in immediately available funds
      to
      the Master Servicer at least three Business Days prior to the applicable
      Distribution Date and, upon receipt of such funds from the NIMS Insurer, the
      Master Servicer shall promptly deposit such funds in the Collection Account.
      The
      NIMS Insurer shall be obligated to reimburse the Master Servicer and the Trustee
      for their reasonable out-of-pocket expenses incurred in connection with the
      purchase of the Mortgage Loans and REO Property related to the Mortgage Pool
      at
      the direction of the NIMS Insurer and shall indemnify and hold harmless the
      Master Servicer and the Trustee for any losses, liabilities or expenses
      resulting from any claims arising out of or based upon the Master Servicer’s or
      Trustee’s purchase of the Pool Assets at the direction of the NIMS Insurer at
      the direction of the NIMS Insurer, except to the extent such losses, liabilities
      or expenses arise out of or result from the Master Servicer’s or Trustee’s, as
      the case may be, negligence, bad faith or willful misconduct.

      to Holders of the related Certificates. Upon any termination pursuant to Section
      7.01(b), the duties of the Certificate Registrar with respect to the applicable
      Certificates shall terminate and the Trustee shall terminate or request the
      Master Servicer to terminate, the Collection Account it maintains, the
      Certificate Account and any other account or fund maintained with respect to
      the
      related Certificates, subject to the Trustee’s obligation hereunder to hold all
      amounts payable to Certificateholders in trust without interest pending such
      payment.

     

    (b) In
      the
      event that all of the Holders do not surrender their Certificates for
      cancellation within three months after the time specified in the above mentioned
      written notice, the Trustee shall give a second written notice to the remaining
      Certificateholders to surrender their Certificates for cancellation and receive
      the final distribution with respect thereto. If within one year after the second
      notice any Certificates shall not have been surrendered for cancellation, the
      Trustee may take appropriate steps to contact the remaining Certificateholders
      concerning surrender of such Certificates, and the cost thereof shall be paid
      out of the amounts distributable to such Holders. If within two years after
      the
      second notice any Certificates shall not have been surrendered for cancellation,
      the Trustee shall, subject to applicable state law relating to escheatment,
      hold
      all amounts distributable to such Holders for the benefit of such Holders.
      No
      interest shall accrue on any amount held by the Trustee and not distributed
      to a
      Certificateholder due to such Certificateholder’s failure to surrender its
      Certificate(s) for payment of the final distribution thereon in accordance
      with
      this Section.

     

    (c) Any
      reasonable expenses incurred by the Trustee in connection with any termination
      or liquidation of the Trust Fund (or a Mortgage Pool thereof) shall be
      reimbursed from proceeds received from the liquidation of the related Mortgage
      Pool or Mortgage Pools.

    Section
      7.03. Additional
      Trust Fund Termination Requirements

     

    Any
      sale
      pursuant to Section 7.01(b) shall be effected in accordance with the following
      additional requirements, unless the Trustee seeks (at the request of the party
      exercising the option to repurchase all of the Mortgage Loans pursuant to
      Section 7.01(b)), and subsequently receives, an Opinion of Counsel (at the
      expense of such requesting party), addressed to the Trustee and any NIMS Insurer
      to the effect that the failure of the Trust Fund to comply with the requirements
      of this Section 7.03 will not (I) result in the imposition of taxes on any
      REMIC
      under the REMIC Provisions or (II) cause any REMIC established hereunder to
      fail
      to qualify as a REMIC at any time that any Certificates are
      outstanding:

     

    (i) The
      Trustee shall sell all of the assets of the Mortgage Pool for cash and, within
      90 days of such sale, shall distribute the proceeds of such sale to the
      Certificateholders in complete liquidation of each REMIC; and

     

    (ii) The
      Trustee shall attach a statement to the final Federal income tax return for
      each
      REMIC stating that pursuant to Treasury Regulation § 1.860F-1, the first day of
      the 90-day liquidation period for each such REMIC was the date on which the
      Trustee sold such assets.

     

    Section
      7.04. Optional
      Purchase Right of NIMS Insurer

     

    The
      NIMS
      Insurer may purchase any Distressed Mortgage Loan for a purchase price equal
      to
      the outstanding principal balance of such Mortgage Loan, plus accrued interest
      thereon to the date of repurchase plus any unreimbursed Advances, Servicing
      Advances, General Servicing Fees or Trustee Fees and any unreimbursed expenses
      of the Trustee allocable to such Distressed Mortgage Loan. Any such purchase
      shall be accomplished by the NIM Insurer’s remittance of the purchase price for
      the Distressed Mortgage Loan to the Master Servicer for deposit into the
      Collection Account.

     

    Section
      7.05. Grantor

      1-A1A Grantor Trust, Class 1-A1B Grantor Trust, the Class 1-A3B Grantor Trust
      and the Class 2-A Grantor Trust each will terminate on the earlier of the date

      CERTIFICATEHOLDERS

     

    Section
      8.01. Limitation
      on Rights of Holders

     

    (a) The
      death
      or incapacity of any Certificateholder shall not operate to terminate this
      Agreement or this Trust Fund, nor entitle such Certificateholder’s legal
      representatives or heirs to claim an accounting or take any action or proceeding
      in any court for a partition or winding up of this Trust Fund, nor otherwise
      affect the rights, obligations and liabilities of the parties hereto or any
      of
      them. Except as otherwise expressly provided herein, no Certificateholder,
      solely by virtue of its status as a Certificateholder, shall have any right
      to
      vote or in any manner otherwise control the Master Servicer or the operation
      and
      management of the Trust Fund, or the obligations of the parties hereto, nor
      shall anything herein set forth, or contained in the terms of the Certificates,
      be construed so as to constitute the Certificateholders from time to time as
      partners or members of an association, nor shall any Certificateholder be under
      any liability to any third person by reason of any action taken by the parties
      to this Agreement pursuant to any provision hereof.

    (b) No
      Certificateholder, solely by virtue of its status as Certificateholder, shall
      have any right by virtue or by availing of any provision of this Agreement
      to
      institute any suit, action or proceeding in equity or at law upon or under
      or
      with respect to this Agreement, unless such Holder previously shall have given
      to the Trustee a written notice of an Event of Default and of the continuance
      thereof, as hereinbefore provided, and unless also the Holders of Certificates
      evidencing not less than 25% of the Class Principal Amount or Class Notional
      Amount (or Percentage Interest) of Certificates of each Class affected thereby
      shall have made written request upon the Trustee to institute such action,
      suit
      or proceeding in its own name as Trustee hereunder and shall have offered to
      the
      Trustee such reasonable indemnity as it may require against the cost, expenses
      and liabilities to be incurred therein or thereby, and the Trustee, for sixty
      days after its receipt of such notice, request and offer of indemnity, shall
      have neglected or refused to institute any such action, suit or proceeding
      and
      no direction inconsistent with such written request has been given such Trustee
      during such sixty day period by such Certificateholders; it being understood
      and
      intended, and being expressly covenanted by each Certificateholder with every
      other Certificateholder and the Trustee, that no one or more Holders of
      Certificates shall have any right in any manner whatever by virtue or by
      availing of any provision of this Agreement to affect, disturb or prejudice
      the
      rights of the Holders of any other of such Certificates, or to obtain or seek
      to
      obtain priority over or preference to any other such Holder, or to enforce
      any
      right under this Agreement, except in the manner herein provided and for the
      benefit of all Certificateholders. For the protection and enforcement of the
      provisions of this Section, each and every Certificateholder and the Trustee
      shall be entitled to such relief as can be given either at law or in
      equity.

     

    Section
      8.02. Access
      to List of Holders

     

    (a) If
      the
      Trustee is not acting as Certificate Registrar, the Certificate Registrar will
      furnish or cause to be furnished to the Trustee, within fifteen days after
      receipt by the Certificate Registrar of a request by the Trustee in writing,
      a
      list, in such form as the Trustee may reasonably require, of the names and
      addresses of the Certificateholders of each Class as of the most recent Record
      Date.

     

    (b) If
      three
      or more Holders or Certificate Owners (hereinafter referred to as “Applicants”)
      apply in writing to the Trustee, and such application states that the Applicants
      desire to communicate with other Holders with respect to their rights under
      this
      Agreement or under the Certificates and is accompanied by a copy of the
      communication which such Applicants propose to transmit, then the Trustee shall,
      within five Business Days after the receipt of such application, afford such
      Applicants reasonable access during the normal business hours of the Trustee
      to
      the most recent list of Certificateholders held by the Trustee or shall, as
      an
      alternative, send, at the Applicants’ expense, the written communication
      proffered by the Applicants to all Certificateholders at their addresses as
      they
      appear in the Certificate Register.

    (c) Every
      Holder or Certificate Owner, if the Holder is a Clearing Agency, by receiving
      and holding a Certificate, agrees with the Depositor, the Master Servicer,
      the
      Certificate Registrar and the Trustee, that none of the Depositor, the Master
      Servicer, the Certificate Registrar, the Paying Agent or the Trustee shall
      be
      held accountable by reason of the disclosure of any such information as to
      the
      names and addresses of the Certificateholders hereunder, regardless of the
      source from which such information was derived.

     

    Section
      8.03. Acts
      of Holders of Certificates

     

    (a) Any
      request, demand, authorization, direction, notice, consent, waiver or other
      action provided by this Agreement to be given or taken by Holders or Certificate
      Owner, if the Holder is a Clearing Agency, may be embodied in and evidenced
      by
      one or more instruments of substantially similar tenor signed by such Holders
      in
      person or by agent duly appointed in writing; and, except as herein otherwise
      expressly provided, such action shall become effective when such instrument
      or
      instruments are delivered to the Trustee, the Certificate Registrar and the
      Paying Agent and, where expressly required herein, to the Master Servicer.
      Such
      instrument or instruments (as the action embodies therein and evidenced thereby)
      are herein sometimes referred to as an “act” of the Holders signing such
      instrument or instruments. Proof of execution of any such instrument or of
      a
      writing appointing any such agents shall be sufficient for any purpose of this
      Agreement and conclusive in favor of the Trustee and the Master Servicer, if
      made in the manner provided in this Section. Each of the Trustee and the Master
      Servicer shall promptly notify the other of receipt of any such instrument
      by
      it, and shall promptly forward a copy of such instrument to the
      other.

     

    (b) The
      fact
      and date of the execution by any Person of any such instrument or writing may
      be
      proved by the affidavit of a witness of such execution or by the certificate
      of
      any notary public or other officer authorized by law to take acknowledgments
      or
      deeds, certifying that the individual signing such instrument or writing
      acknowledged to him the execution thereof. Whenever such execution is by an
      officer of a corporation or a member of a partnership on behalf of such
      corporation or partnership, such certificate or affidavit shall also constitute
      sufficient proof of his authority. The fact and date of the execution of any
      such instrument or writing, or the authority of the individual executing the
      same, may also be proved in any other manner which the Trustee deems
      sufficient.

     

    (c) The
      ownership of Certificates (whether or not such Certificates shall be overdue
      and
      notwithstanding any notation of ownership or other writing thereon made by
      anyone other than the Trustee) shall be proved by the Certificate Register,
      and
      none of the Trustee, the Master Servicer, the Paying Agent or the Depositor
      shall be affected by any notice to the contrary.

     

    (d) Any
      request, demand, authorization, direction, notice, consent, waiver or other
      action by the Holder of any Certificate shall bind every future Holder of the
      same Certificate and the Holder of every Certificate issued upon the
      registration of transfer thereof or in exchange therefor or in lieu thereof,
      in
      respect of anything done, omitted or suffered to be done by the Trustee or
      the
      Master Servicer in reliance thereon, whether or not notation of such action
      is
      made upon such Certificate.

    ADMINISTRATION
      AND SERVICING OF MORTGAGE LOANS

    BY
      THE
      MASTER SERVICER

     

    Section
      9.01. Duties
      of the Master Servicer

     

    The
      Certificateholders, by their purchase and acceptance of the Certificates,
      appoint Aurora Loan Services LLC, as Master Servicer. For and on behalf of
      the
      Depositor, the Trustee and the Certificateholders, the Master Servicer shall
      master service the Mortgage Loans in accordance with the provisions of this
      Agreement and the provisions of the Servicing Agreements.

     

    Section
      9.02. Master
      Servicer Fidelity Bond and Master Servicer Errors and Omissions Insurance
      Policy

     

    (a) The
      Master Servicer, at its expense, shall maintain in effect a Master Servicer
      Fidelity Bond and a Master Servicer Errors and Omissions Insurance Policy,
      affording coverage with respect to all directors, officers, employees and other
      Persons acting on such Master Servicer’s behalf, and covering errors and
      omissions in the performance of the Master Servicer’s obligations hereunder. The
      Master Servicer Errors and Omissions Insurance Policy and the Master Servicer
      Fidelity Bond shall be in such form and amount that would meet the requirements
      of Fannie Mae or Freddie Mac if it were the purchaser of the Mortgage Loans,
      and
      if the Master Servicer receives notice that such policy is or shall be
      cancelled, it shall immediately notify the NIMS Insurer. The Master Servicer
      shall provide the Trustee and any NIMS Insurer upon request, with a copy of
      such
      policy and fidelity bond. The Master Servicer shall (i) require each Servicer
      to
      maintain an Errors and Omissions Insurance Policy and the Servicer Fidelity
      Bond
      in accordance with the provisions of the applicable Servicing Agreement, (ii)
      cause each Servicer to provide to the Master Servicer certificates evidencing
      that such policy and bond is in effect and to furnish to the Master Servicer
      any
      notice of cancellation, non-renewal or modification of the policy or bond
      received by it, as and to the extent provided in the applicable Servicing
      Agreement, and (iii) furnish copies of such policies and of the certificates
      and
      notices referred to in clause (ii) to the Trustee upon request. The Fidelity
      Bond and Errors and Omissions Insurance Policy may be obtained and maintained
      in
      blanket form.

     

    (b) The
      Master Servicer shall promptly report to the Trustee any material changes that
      may occur in the Master Servicer Fidelity Bond or the Master Servicer Errors
      and
      Omissions Insurance Policy and shall furnish to the Trustee, on request,
      certificates evidencing that such bond and insurance policy are in full force
      and effect. The Master Servicer shall promptly report to the Trustee all cases
      of embezzlement or fraud, if such events involve funds relating to the Mortgage
      Loans. The total losses, regardless of whether claims are filed with the
      applicable insurer or surety, shall be disclosed in such reports together with
      the amount of such losses covered by insurance. If a bond or insurance claim
      report is filed with any of such bonding companies or insurers, the Master
      Servicer shall promptly furnish a copy of such report to the Trustee. Any
      amounts relating to the Mortgage Loans collected by the Master Servicer under
      any such bond or policy shall be promptly remitted by the Master Servicer to
      the
      Trustee for deposit into the Certificate Account. Any amounts relating to the
      Mortgage Loans collected by a Servicer under any such bond or policy shall
      be
      remitted to the Master Servicer to the extent provided in the applicable
      Servicing Agreement.

    Section
      9.03. Master
      Servicer’s Financial Statements and Related Information

     

    For
      each
      year this Agreement is in effect, the Master Servicer shall submit to the
      Trustee, each Rating Agency and the Depositor a copy of the annual audited
      financial statements of its parent on or prior to March 31st of each year
      commencing on March 31, 2007. Such financial statements shall include
      comparative balance sheets, income statements, statement of changes in
      shareholder's equity, statements of cash flows, a consolidating schedule showing
      consolidated subsidiaries and any related notes required pursuant to generally
      accepted accounting principles, certified by a nationally recognized firm of
      Independent Accountants to the effect that such financial statements were
      examined and prepared in accordance with generally accepted accounting
      principles applied on a basis consistent with that of the preceding
      year.

     

    Section
      9.04. Power
      to Act; Procedures

     

    (a) The
      Master Servicer shall master service the Mortgage Loans and shall have full
      power and authority, subject to the REMIC Provisions and the provisions of
      Article X hereof, and each Servicer shall have full power and authority (to
      the
      extent provided in the applicable Servicing Agreement) to do any and all things
      that it may deem necessary or desirable in connection with the servicing and
      administration of the Mortgage Loans, including but not limited to the power
      and
      authority (i) to execute and deliver, on behalf of the Certificateholders and
      the Trustee, customary consents or waivers and other instruments and documents,
      (ii) to consent to transfers of any Mortgaged Property and assumptions of the
      Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds
      and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion
      of the ownership of the Mortgaged Property securing any Mortgage Loan, in each
      case, in accordance with the provisions of this Agreement and the applicable
      Servicing Agreement, as applicable; provided that the Master Servicer shall
      not
      take, or knowingly permit any Servicer to take, any action that is inconsistent
      with or prejudices the interests of the Trust Fund or the Certificateholders
      in
      any Mortgage Loan or the rights and interests of the Depositor, the Trustee,
      or
      the Certificateholders under this Agreement. The Master Servicer further is
      authorized and empowered by the Trustee, on behalf of the Certificateholders
      and
      the Trustee, in its own name or in the name of any Servicer (to the extent
      permitted in the applicable Servicing Agreement), when the Master Servicer
      or a
      Servicer, as the case may be, believes it is appropriate in its best judgment
      to
      register any Mortgage Loan with MERS, or cause the removal from the registration
      of any Mortgage Loan on the MERS system, to execute and deliver, on behalf
      of
      the Trustee and the Certificateholders or any of them, any and all instruments
      of assignment and other comparable instruments with respect to such assignment
      or re-recording of a Mortgage in the name of MERS, solely as nominee for the
      Trustee and its successors and assigns. The Master Servicer shall represent
      and
      protect the interests of the Trust Fund in the same manner as it protects its
      own interests in mortgage loans in its own portfolio in any claim, proceeding
      or
      litigation regarding a Mortgage Loan and shall not make or knowingly permit
      any
      Servicer to make any modification, waiver or amendment of any term of any
      Mortgage Loan that would cause an Adverse REMIC Event. Without limiting the
      generality of the foregoing, the Master Servicer in its own name or in the
      name
      of a Servicer, and each Servicer, to the extent such authority is delegated
      to
      such Servicer under the applicable Servicing Agreement, is hereby authorized
      and
      empowered by the Trustee when the Master Servicer or a Servicer, as the case
      may
      be, believes it appropriate in its best judgment and in accordance with Accepted
      Servicing Practices and the applicable Servicing Agreement, to execute and
      deliver, on behalf of itself and the Certificateholders, the Trustee or any
      of
      them, any and all instruments of satisfaction or cancellation, or of partial
      or
      full release or discharge and all other comparable instruments, with respect
      to
      the Mortgage Loans and with respect to the Mortgaged Properties. The Trustee
      shall execute, upon request, any powers of attorney furnished to it by the
      Master Servicer empowering the Master Servicer or such Servicer to execute
      and
      deliver instruments of satisfaction or cancellation, or of partial or full
      release or discharge, and to foreclose upon or otherwise liquidate Mortgaged
      Property, and to appeal, prosecute or defend in any court action relating to
      the
      Mortgage Loans or the Mortgaged Property, in accordance with the applicable
      Servicing Agreement and this Agreement, and the Trustee shall execute and
      deliver such other documents, as the Master Servicer may request, necessary
      or
      appropriate to enable the Master Servicer to master service the Mortgage Loans
      and carry out its duties hereunder and to allow each Servicer to service the
      Mortgage Loans, in each case in accordance with Accepted Servicing Practices
      (and the Trustee shall have no liability for misuse of any such powers of
      attorney by the Master Servicer or the applicable Servicer). If the Master
      Servicer or the Trustee has been advised that it is likely that the laws of
      the
      state in which action is to be taken prohibit such action if taken in the name
      of the Trustee or that the Trustee would be adversely affected under the “doing
      business” or tax laws of such state if such action is taken in its name, then
      upon request of the Trustee the Master Servicer shall join with the Trustee
      in
      the appointment of a co-trustee pursuant to Section 6.09 hereof. In the
      performance of its duties hereunder, the Master Servicer shall be an independent
      contractor and shall not, except in those instances where it is taking action
      in
      the name of the Trustee, be deemed to be the agent of the Trustee.
      Notwithstanding anything to the contrary, the Master Servicer shall not without
      the Trustee’s written consent: (i) initiate any action, suit or proceeding
      solely under the Trustee’s name without indicating the Master Servicer’s
      representative capacity or (ii) take any action with the intent to cause, and
      which actually does cause, the Trustee to be registered to do business in any
      state.

    (b) In
      master
      servicing and administering the Mortgage Loans, the Master Servicer shall employ
      procedures, and shall exercise the same care that it customarily employs and
      exercises master servicing and administering loans for its own account, giving
      due consideration to Accepted Servicing Practices where such practices do not
      conflict with this Agreement. Consistent with the foregoing, the Master Servicer
      may, and may permit the Servicer to, in its discretion (i) waive any late
      payment charge (but not any Prepayment Premium, except as set forth below)
      and
      (ii) extend the due dates for payments due on a Mortgage Note for a period
      not
      greater than 120 days; provided, however, that the maturity of any Mortgage
      Loan
      shall not be extended past the date on which the final payment is due on the
      latest maturing Mortgage Loan as of the Cut-off Date. In the event of any
      extension described in clause (ii) above, the Master Servicer shall make
      Advances on the related Mortgage Loan in accordance with the provisions of
      Section 5.04 on the basis of the amortization schedule of such Mortgage Loan
      without modification thereof by reason of such extension. Notwithstanding
      anything to the contrary in this Agreement, the Master Servicer shall not make
      or knowingly permit any modification, waiver or amendment of any material term
      of any Mortgage Loan unless: (1) such Mortgage Loan is in default or default
      by
      the related Mortgagor is, in the reasonable judgment of the Master Servicer
      or
      the applicable Servicer, reasonably foreseeable, (2) in the case of a waiver
      of
      a Prepayment Premium if (a) such Mortgage Loan is in default or default by
      the
      related Mortgagor is, in the reasonable judgment of the Master Servicer or
      Servicer, reasonably foreseeable, and such waiver would maximize recovery of
      total proceeds taking into account the value of such Prepayment Premium and
      the
      related Mortgage Loan or (b) if the prepayment is not the result of a
      refinancing by the Servicer or any of its Affiliates and (i) such Mortgage
      Loan
      is in default or default by the related Mortgagor is, in the reasonable judgment
      of the Master Servicer or the applicable Servicer, reasonably foreseeable,
      and
      such waiver would maximize recovery of total proceeds taking into account the
      value of such Prepayment Premium and the related Mortgage Loan or (ii) the
      collection of the Prepayment Premium would be in violation of applicable laws
      or
      (iii) the collection of such Prepayment Premium would be considered “predatory”
pursuant to written guidance published or issued by any applicable federal,
      state or local regulatory authority acting in its official capacity and having
      jurisdiction over such matters, and (3) the Master Servicer shall have provided
      or caused to be provided to the Trustee an Opinion of Counsel addressed to
      the
      Trustee (which opinion shall, if provided by the Master Servicer, be an expense
      reimbursed from the Collection Account pursuant to Section 4.02(v)) in writing
      to the effect that such modification, waiver or amendment would not cause an
      Adverse REMIC Event; provided, in no event shall an Opinion of Counsel be
      required for the waiver of a Prepayment Premium under clause (2)
      above.

    Section
      9.05. Enforcement
      of Servicers’ and Master Servicer’s Obligations

     

    (a) Each
      Servicing Agreement requires the applicable Servicer to service the Mortgage
      Loans in accordance with the provisions thereof. References in this Agreement
      to
      actions taken or to be taken by the Master Servicer include actions taken or
      to
      be taken by a Servicer on behalf of the Master Servicer. Any fees, costs,
      expenses and other amounts payable to such Servicer shall be deducted from
      amounts remitted to the Master Servicer by the Servicer to the extent permitted
      by the applicable Servicing Agreement and shall not be an obligation of the
      Trust Fund, the Trustee or the Master Servicer.

     

    (b) The
      Master Servicer shall not be required to (i) take any action with respect to
      the
      servicing of any Mortgage Loan that the applicable Servicer is not required
      to
      take under the related Servicing Agreement and (ii) cause a Servicer to take
      any
      action or refrain from taking any action if the related Servicing Agreement
      does
      not require such Servicer to take such action or refrain from taking such
      action; in both cases notwithstanding any provision of this Agreement that
      requires the Master Servicer to take such action or cause such Servicer to
      take
      such action.

     

    (c) The
      Master Servicer, for the benefit of the Trustee and the Certificateholders,
      shall use its reasonable best efforts to enforce the obligations of each
      Servicer under the related Servicing Agreement, and shall, upon obtaining actual
      knowledge of the failure of a Servicer to perform its obligations in accordance
      therewith, to the extent that such non-performance of such obligations would
      have a material adverse effect on a Mortgage Loan, the Trust Fund or the
      Certificateholders, terminate the rights and obligations of such Servicer
      thereunder and either act as servicer of the related Mortgage Loans or cause
      the
      other parties hereto to enter into a Servicing Agreement (and such parties
      hereby agree to execute and deliver any such successor Servicing Agreement),
      with a successor Servicer. Such enforcement, including, without limitation,
      the
      legal prosecution of claims, termination of Servicing Agreements and the pursuit
      of other appropriate remedies, shall be in such form and carried out to such
      an
      extent and at such time as the Master Servicer, in its good faith business
      judgment, would require were it the owner of the related Mortgage Loans. The
      Master Servicer shall pay the costs of such enforcement at its own expense,
      and
      shall be reimbursed therefor initially (i) from a general recovery resulting
      from such enforcement only to the extent, if any, that such recovery exceeds
      all
      amounts due in respect of the related Mortgage Loans, (ii) from a specific
      recovery of costs, expenses or attorneys’ fees against the party against whom
      such enforcement is directed, and then, (iii) to the extent that such amounts
      are insufficient to reimburse the Master Servicer for the costs of such
      enforcement, from the Collection Account.

    (d) The
      Master Servicer shall be entitled to conclusively rely on any certifications
      or
      other information provided by the Servicers under the terms of the applicable
      Servicing Agreement, in its preparation of any certifications, notifications,
      filings or reports, in accordance with the terms hereof or as may be required
      by
      applicable law or regulation.

     

    Section
      9.06. Collection
      of Taxes, Assessments and Similar Items

     

    (a) To
      the
      extent provided in the applicable Servicing Agreement, the Master Servicer
      shall
      cause each Servicer to establish and maintain one or more custodial accounts
      at
      a depository institution (which may be a depository institution with which
      the
      Master Servicer or the Servicer establishes accounts in the ordinary course
      of
      its servicing activities), the accounts of which are insured to the maximum
      extent permitted by the FDIC (each, an “Escrow Account”) and to deposit therein
      any collections of amounts received with respect to amounts due for taxes,
      assessments, water rates, Standard Hazard Insurance Policy premiums, Payaheads,
      if applicable, or any comparable items for the account of the Mortgagors.
      Withdrawals from any Escrow Account may be made (to the extent amounts have
      been
      escrowed for such purpose) only in accordance with the Servicing Agreements.
      Each Servicer shall be entitled to all investment income not required to be
      paid
      to Mortgagors on any Escrow Account maintained by such Servicer. The Master
      Servicer shall make (or cause to be made) to the extent provided in the
      applicable Servicing Agreement advances to the extent necessary in order to
      effect timely payment of taxes, water rates, assessments, Standard Hazard
      Insurance Policy premiums or comparable items in connection with the related
      Mortgage Loan (to the extent that the Mortgagor is required, but fails, to
      pay
      such items), provided that it or the applicable Servicer has determined that
      the
      funds so advanced are recoverable from escrow payments, reimbursement pursuant
      to Section 4.02 or otherwise.

     

    (b) Costs
      incurred by the Master Servicer or by the Servicers in effecting the timely
      payment of taxes and assessments on the properties subject to the Mortgage
      Loans
      may be added to the amount owing under the related Mortgage Note where the
      terms
      of the Mortgage Note so permit; provided, however, that the addition of any
      such
      cost shall not be taken into account for purposes of calculating the
      distributions to be made to Certificateholders. Such costs, to the extent that
      they are unanticipated, extraordinary costs, and not ordinary or routine costs
      shall be recoverable as a Servicing Advance by the Master Servicer pursuant
      to
      Section 4.02.

     

    
      
        
        

      

      
        -128-

        
          

        

      

      
        
        

      

    

     

    Section
      9.07. Termination
      of Servicing Agreements; Successor Servicers

     

    (a) The
      Master Servicer shall be entitled to terminate the rights and obligations of
      any
      Servicer under the applicable Servicing Agreement in accordance with the terms
      and conditions of such Servicing Agreement and without any limitation by virtue
      of this Agreement; provided, however, that in the event of termination of any
      Servicing Agreement by the Master Servicer or a related Servicer, the Master
      Servicer shall either act as Servicer of the related Mortgage Loans or provide
      for the servicing of the Mortgage Loans by a successor Servicer to be appointed
      as provided in the related Servicing Agreement.

     

    The
      parties acknowledge that notwithstanding the preceding sentence, there may
      be a
      transition period, not to exceed 90 days, in order to effect the transfer of
      servicing to a successor Servicer. The Master Servicer shall be entitled to
      be
      reimbursed from each Servicer (or by the Trust Fund, if such Servicer is unable
      to fulfill its obligations hereunder) for all costs associated with the transfer
      of servicing from the predecessor servicer, including without limitation, any
      costs or expenses associated with the complete transfer of all servicing data
      and the completion, correction or manipulation of such servicing data, as may
      be
      required by the Master Servicer to correct any errors or insufficiencies in
      the
      servicing data or otherwise to enable the Master Servicer to service the
      Mortgage Loans properly and effectively.

     

    (b) If
      the
      Master Servicer acts as a successor Servicer, it will not assume liability
      for
      the representations and warranties of the Servicer, if any, that it replaces.
      The Master Servicer shall use reasonable efforts to have the successor Servicer
      assume liability for the representations and warranties made by the terminated
      Servicer in the related Servicing Agreement, and in the event of any such
      assumption by the successor Servicer, the Trustee or the Master Servicer, as
      applicable, may, in the exercise of its business judgment, release the
      terminated Servicer from liability for such representations and
      warranties.

     

    (c) If
      the
      Master Servicer acts as a successor servicer, it will have no obligation to
      make
      an Advance if it determines in its reasonable judgment that such Advance is
      non-recoverable. To the extent that the Master Servicer is unable to find a
      successor servicer that is willing to service the Mortgage Loans for the
      Servicing Fee because of the obligation of the servicer to make Advances
      regardless of whether such Advance is recoverable, the applicable Servicing
      Agreement may be amended to provide that the successor servicer shall have
      no
      obligation to make an Advance if it determines in its reasonable judgment that
      such Advance is non-recoverable and provides an Officer’s Certificate to such
      effect to the Master Servicer and the Trustee.

     

    Section
      9.08. Master
      Servicer Liable for Enforcement

     

    Notwithstanding
      any Servicing Agreement, the Master Servicer shall remain obligated and liable
      to the Trustee and the Certificateholders in accordance with the provisions
      of
      this Agreement, to the extent of its obligations hereunder, without diminution
      of such obligation or liability by virtue of such Servicing Agreements. The
      Master Servicer shall use commercially reasonable efforts to ensure that the
      Mortgage Loans are serviced in accordance with the provisions of this Agreement
      and shall use commercially reasonable efforts to enforce the provisions of
      each
      Servicing Agreement for the benefit of the Certificateholders. The Master
      Servicer shall be entitled to enter into any agreement with the Servicers for
      indemnification of the Master Servicer and nothing contained in this Agreement
      shall be deemed to limit or modify such indemnification. Except as expressly
      set
      forth herein, the Master Servicer shall have no liability for the acts or
      omissions of any Servicer in the performance by such Servicer of its obligations
      under the related Servicing Agreement.

    Section
      9.09. No
      Contractual Relationship Between the Servicer, Any NIMS Insurer and Trustee
      or
      Depositor

     

    Any
      Servicing Agreement and any other transactions or services relating to the
      Mortgage Loans involving a Servicer in its capacity as such and not as an
      originator shall be deemed to be between such Servicer, the Seller and the
      Master Servicer, and the Trustee and the Depositor shall not be deemed parties
      thereto and shall have no obligations, duties or liabilities with respect to
      such Servicer except as set forth in Section 9.10 hereof, but shall have rights
      thereunder as third party beneficiaries.

     

    Section
      9.10. Assumption
      of Servicing Agreement by the Trustee

     

    (a) In
      the
      event the Master Servicer shall for any reason no longer be the Master Servicer
      (including by reason of any Event of Default under this Agreement), after a
      period not to exceed ninety days after the issuance of any notice of termination
      pursuant to Section 6.14 or Section 9.28, as applicable, the Trustee, or a
      successor master servicer appointed by it in accordance with Section 6.14,
      shall
      assume all of the rights and obligations of such Master Servicer hereunder
      and
      under each Servicing Agreement entered into with respect to the Mortgage Loans.
      The Trustee, its designee or any successor master servicer appointed by the
      Trustee shall be deemed to have assumed all of the Master Servicer’s interest
      herein and therein to the same extent as if such Servicing Agreement had been
      assigned to the assuming party, except that the Master Servicer shall not
      thereby be relieved of any liability or obligations of the Master Servicer
      under
      such Servicing Agreement accruing prior to its replacement as Master Servicer,
      and shall be liable to the Trustee, and hereby agrees to indemnify and hold
      harmless the Trustee from and against all costs, damages, expenses and
      liabilities (including reasonable attorneys’ fees) incurred by the Trustee as a
      result of such liability or obligations of the Master Servicer and in connection
      with the Trustee’s assumption (but not its performance, except to the extent
      that costs or liability of the Trustee are created or increased as a result
      of
      negligent or wrongful acts or omissions of the Master Servicer prior to its
      replacement as Master Servicer) of the Master Servicer’s obligations, duties or
      responsibilities thereunder; provided that the Master Servicer shall not
      indemnify or hold harmless the Trustee against negligent or willful misconduct
      of the Trustee.

     

    (b) The
      Master Servicer that has been terminated shall, upon request of the Trustee
      but
      at the expense of such Master Servicer or at the expense of the Trust Fund,
      deliver to the assuming party all documents and records relating to each
      Servicing Agreement and the related Mortgage Loans and an accounting of amounts
      collected and held by it and otherwise use its best efforts to effect the
      orderly and efficient transfer of each Servicing Agreement to the assuming
      party.

    Section
      9.11. Due-on-Sale
      Clauses; Assumption Agreements; Easements

     

    (a) To
      the
      extent provided in the applicable Servicing Agreement, to the extent Mortgage
      Loans contain enforceable due on sale clauses, and to the extent that the Master
      Servicer has knowledge of the conveyance of a Mortgaged Property, the Master
      Servicer shall use its reasonable best efforts to cause the Servicers to enforce
      such clauses in accordance with the applicable Servicing Agreement. If
      applicable law prohibits the enforcement of a due on sale clause or such clause
      is otherwise not enforced in accordance with the applicable Servicing Agreement,
      and, as a consequence, a Mortgage Loan is assumed, the original Mortgagor may
      be
      released from liability in accordance with the applicable Servicing Agreement.
      

     

    (b) The
      Master Servicer or the related Servicer, as the case may be, shall be entitled
      to approve a request from a Mortgagor for the granting of an easement thereon
      in
      favor of another Person or any alteration or demolition of the related Mortgaged
      Property if it has determined, exercising its good faith business judgment
      in
      the same manner as it would if it were the owner of the related Mortgage Loan,
      that the security for, and the timely and full collectability of, such Mortgage
      Loan would not be materially adversely affected thereby. Any fee collected
      by
      the Master Servicer or the related Servicer for processing such a request will
      be retained by the Master Servicer or such Servicer as additional servicing
      compensation.

     

    Section
      9.12. Release
      of Mortgage Files

     

    (a) Upon
      (i)
      becoming aware of the payment in full of any Mortgage Loan or (ii) the receipt
      by the Master Servicer of a notification that payment in full has been or will
      be escrowed in a manner customary for such purposes, the Master Servicer shall,
      or shall cause the applicable Servicer to, promptly notify the Trustee (or
      the
      Custodian) by a certification (which certification shall include a statement
      to
      the effect that all amounts received in connection with such payment that are
      required to be deposited in the Collection Account maintained by the Master
      Servicer pursuant to Section 4.01 hereof have been or will be so deposited)
      of a
      Servicing Officer and shall request (on the form attached hereto as Exhibit
      C or
      on the form attached to the Custodial Agreement) the Trustee or the Custodian,
      to deliver to the applicable Servicer the related Mortgage File; provided,
      however, that in lieu of sending a hard copy certification of a Servicing
      Officer, the Master Servicer may, or may cause the applicable Servicer to,
      deliver the request for release in a mutually agreeable electronic format,
      and
      to the extent that such a request, on its face, originates from a Servicing
      Officer, no original signature shall be required. Upon receipt of such
      certification and request, the Trustee or the Custodian, shall promptly release
      the related Mortgage File to the Servicer and neither the Trustee nor the
      Custodian shall have any further responsibility with regard to such Mortgage
      File. Upon any such payment in full, the Master Servicer is authorized, and
      the
      applicable Servicer, to the extent such authority is provided for under the
      related Servicing Agreement, is authorized, to give, as agent for the Trustee,
      as the mortgagee under the Mortgage that secured the Mortgage Loan, an
      instrument of satisfaction (or assignment of mortgage without recourse)
      regarding the Mortgaged Property subject to the Mortgage, which instrument
      of
      satisfaction or assignment, as the case may be, shall be delivered to the Person
      or Persons entitled thereto against receipt therefor of such payment, it being
      understood and agreed that no expenses incurred in connection with such
      instrument of satisfaction or assignment, as the case may be, shall be
      chargeable to the Collection Account.

    (b) From
      time
      to time and as appropriate for the servicing or foreclosure of any Mortgage
      Loan
      and in accordance with Accepted Servicing Practices and the applicable Servicing
      Agreement, the Trustee shall execute such documents as shall be prepared and
      furnished to the Trustee by the Master Servicer, or by the applicable Servicer
      (in form reasonably acceptable to the Trustee) and as are necessary to the
      prosecution of any such proceedings. The Trustee or the Custodian, shall, upon
      request of the Master Servicer, or of the applicable Servicer, and delivery
      to
      the Trustee or the Custodian, of a trust receipt signed by a Servicing Officer
      substantially in the form of Exhibit C, release the related Mortgage File held
      in its possession or control to the Master Servicer (or the applicable
      Servicer). Such trust receipt shall obligate the Master Servicer or applicable
      Servicer to return the Mortgage File to the Trustee or the Custodian, as
      applicable, when the need therefor by the Master Servicer or applicable Servicer
      no longer exists unless (i) the Mortgage Loan shall be liquidated, in which
      case, upon receipt of a certificate of a Servicing Officer similar to that
      hereinabove specified, the trust receipt shall be released by the Trustee or
      the
      Custodian, as applicable, to the Master Servicer (or the applicable Servicer)
      or
      (ii) the Mortgage File has been delivered directly or through a Servicer to
      an
      attorney, or to a public trustee or other public official as required by law,
      for purposes of initiating or pursuing legal action or other proceedings for
      the
      foreclosure of the Mortgaged Property either judicially or non-judicially,
      and
      the Master Servicer has delivered directly or through a Servicer to the Trustee
      a certificate of a Servicing Officer certifying as to the name and address
      of
      the Person to which such Mortgage File or such document was delivered and the
      purpose of such delivery.

      9.13. Documents,

    (a) The
      Master Servicer shall transmit, or shall cause the applicable Servicer to
      transmit, to the Trustee such documents and instruments coming into the
      possession of the Master Servicer or such Servicer from time to time as are
      required by the terms hereof or of the related Servicing Agreement to be
      delivered to the Trustee or the Custodian. Any funds received by the Master
      Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise
      are
      collected by the Master Servicer or a Servicer as a Subsequent Recovery,
      Liquidation Proceeds or Insurance Proceeds in respect of any Mortgage Loan
      shall
      be held for the benefit of the Trustee and the Certificateholders subject to
      the
      Master Servicer’s right to retain or withdraw from the Collection Account the
      Master Servicing Fee, the General Servicing Fee and other amounts provided
      in
      this Agreement and to the right of each Servicer to retain its Servicing Fee
      and
      other amounts as provided in the Servicing Agreement. The Master Servicer shall,
      and shall (to the extent provided in the applicable Servicing Agreement) cause
      each Servicer to, provide access to information and documentation regarding
      the
      Mortgage Loans to the Trustee, its agents and accountants and any NIMS Insurer,
      at any time upon reasonable request and during normal business hours, and to
      Certificateholders that are savings and loan associations, banks or insurance
      companies, the Office of Thrift Supervision, the FDIC and the supervisory agents
      and examiners of such Office and Corporation or examiners of any other federal
      or state banking or insurance regulatory authority if so required by applicable
      regulations of the Office of Thrift Supervision or other regulatory authority,
      such access to be afforded without charge but only upon reasonable request
      in
      writing and during normal business hours at the offices of the Master Servicer
      designated by it. In fulfilling such a request the Master Servicer shall not
      be
      responsible for determining the sufficiency of such information. The Master
      Servicer shall afford the NIMS Insurer, and shall (to the extent provided in
      the
      Servicing Agreement) cause the Servicer to afford the NIMS Insurer, upon
      reasonable advance notice, during normal business hours access to all records
      related to their respective rights and obligations hereunder and access to
      officers of the Master Servicer and the Servicer responsible for such
      obligations.

    (b) All
      Mortgage Files and funds collected or held by, or under the control of, the
      Master Servicer, or any Servicer, in respect of any Mortgage Loans, whether
      from
      the collection of principal and interest payments or from a Subsequent Recovery,
      Liquidation Proceeds or Insurance Proceeds, shall be held by the Master
      Servicer, or by such Servicer, for and on behalf of the Trustee and the
      Certificateholders and shall be and remain the sole and exclusive property
      of
      the Trustee; provided, however, that the Master Servicer and each Servicer
      shall
      be entitled to setoff against, and deduct from, any such funds any amounts
      that
      are properly due and payable to the Master Servicer or such Servicer under
      this
      Agreement or the applicable Servicing Agreement and shall be authorized to
      remit
      such funds to the Trustee in accordance with this Agreement.

     

    (c) The
      Master Servicer hereby acknowledges that concurrently with the execution of
      this
      Agreement, the Trustee shall own or, to the extent that a court of competent
      jurisdiction shall deem the conveyance of the Mortgage Loans from the Seller
      to
      the Depositor not to constitute a sale, the Trustee shall have a security
      interest in the Mortgage Loans and in all Mortgage Files representing such
      Mortgage Loans and in all funds and investment property now or hereafter held
      by, or under the control of, a Servicer or the Master Servicer that are
      collected by such Servicer or the Master Servicer in connection with the
      Mortgage Loans, whether as scheduled installments of principal and interest
      or
      as full or partial prepayments of principal or interest or as a Subsequent
      Recovery, Liquidation Proceeds or Insurance Proceeds or otherwise, and in all
      proceeds of the foregoing and proceeds of proceeds (but excluding any fee or
      other amounts to which such Servicer is entitled under the applicable Servicing
      Agreement, or the Master Servicer or the Depositor is entitled to hereunder);
      and the Master Servicer agrees that so long as the Mortgage Loans are assigned
      to and held by the Trustee or the Custodian, all documents or instruments
      constituting part of the Mortgage Files, and such funds relating to the Mortgage
      Loans which come into the possession or custody of, or which are subject to
      the
      control of, the Master Servicer or any Servicer shall be held by the Master
      Servicer or such Servicer for and on behalf of the Trustee as the Trustee’s
      agent and bailee for purposes of perfecting the Trustee’s security interest
      therein as provided by the applicable Uniform Commercial Code or other
      applicable laws.

     

    (d) The
      Master Servicer agrees that it shall not, and shall not authorize any Servicer
      to, create, incur or subject any Mortgage Loans, or any funds that are deposited
      in any Custodial Account, Escrow Account or the Collection Account, or any
      funds
      that otherwise are or may become due or payable to the Trustee, to any claim,
      lien, security interest, judgment, levy, writ of attachment or other
      encumbrance, nor assert by legal action or otherwise any claim or right of
      setoff against any Mortgage Loan or any funds collected on, or in connection
      with, a Mortgage Loan.

    Section
      9.14. Representations
      and Warranties of the Master Servicer

     

    (a) The
      Master Servicer hereby represents and warrants to the Depositor and the Trustee,
      for the benefit of the Certificateholders, as of the Closing Date
      that:

     

    (i) it
      is
      validly existing and in good standing under the laws of the State of Delaware,
      and as Master Servicer has full power and authority to transact any and all
      business contemplated by this Agreement and to execute, deliver and comply
      with
      its obligations under the terms of this Agreement, the execution, delivery
      and
      performance of which have been duly authorized by all necessary corporate action
      on the part of the Master Servicer;

     

    (ii) the
      execution and delivery of this Agreement by the Master Servicer and its
      performance and compliance with the terms of this Agreement will not (A) violate
      the Master Servicer’s charter or bylaws, (B) violate any law or regulation or
      any administrative decree or order to which it is subject or (C) constitute
      a
      default (or an event which, with notice or lapse of time, or both, would
      constitute a default) under, or result in the breach of, any material contract,
      agreement or other instrument to which the Master Servicer is a party or by
      which it is bound or to which any of its assets are subject, which violation,
      default or breach would materially and adversely affect the Master Servicer’s
      ability to perform its obligations under this Agreement;

     

    (iii) this
      Agreement constitutes, assuming due authorization, execution and delivery hereof
      by the other respective parties hereto, a legal, valid and binding obligation
      of
      the Master Servicer, enforceable against it in accordance with the terms hereof,
      except as such enforcement may be limited by bankruptcy, insolvency,
      reorganization, moratorium and other laws affecting the enforcement of
      creditors’ rights in general, and by general equity principles (regardless of
      whether such enforcement is considered in a proceeding in equity or at
      law);

     

    (iv) the
      Master Servicer is not in default with respect to any order or decree of any
      court or any order or regulation of any federal, state, municipal or
      governmental agency to the extent that any such default would materially and
      adversely affect its performance hereunder;

     

    (v) the

      subject to any charter provision, bylaw or any other corporate restriction
      or
      any judgment, order, writ, injunction, decree, law or regulation that may
      materially and adversely affect its ability as Master Servicer to perform its
      obligations under this Agreement or that requires the consent of any third
      person to the execution of this Agreement or the performance by the Master
      Servicer of its obligations under this Agreement;

     

    (vi) no
      litigation is pending or, to the best of the Master Servicer’s knowledge,
      threatened against the Master Servicer which would prohibit its entering into
      this Agreement or performing its obligations under this Agreement;

     

    (vii) the
      Master Servicer, or an Affiliate thereof the primary business of which is the
      servicing of conventional residential mortgage loans, is a Fannie Mae- or
      Freddie Mac-approved seller/servicer;

     

    (viii) no
      consent, approval, authorization or order of any court or governmental agency
      or
      body is required for the execution, delivery and performance by the Master
      Servicer of or compliance by the Master Servicer with this Agreement or the
      consummation of the transactions contemplated by this Agreement, except for
      such
      consents, approvals, authorizations and orders (if any) as have been
      obtained;

     

    
      
        
        

      

      
        -134-

        
          

        

      

      
        
        

      

    

     

    (ix) the
      consummation of the transactions contemplated by this Agreement are in the
      ordinary course of business of the Master Servicer;

     

    (x) the
      Master Servicer has obtained an Errors and Omissions Insurance Policy and a
      Fidelity Bond in accordance with Section 9.02 each of which is in full force
      and
      effect, and each of which provides at least such coverage as is required
      hereunder; and

     

    (xi) the
      information about the Master Servicer under the heading “The Master Servicer” in
      the Prospectus relating to the Master Servicer does not include an untrue
      statement of a material fact and does not omit to state a material fact, with
      respect to the statements made, necessary in order to make the statements in
      light of the circumstances under which they were made not
      misleading.

     

    (b) It
      is
      understood and agreed that the representations and warranties set forth in
      this
      Section 9.14 shall survive the execution and delivery of this Agreement. The
      Master Servicer shall indemnify the Depositor and the Trustee and hold them
      harmless against any loss, damages, penalties, fines, forfeitures, legal fees
      and related costs, judgments, and other costs and expenses arising out of or
      based upon any claim, demand, defense or assertion based on or grounded upon,
      or
      resulting from, a breach of the Master Servicer’s representations and warranties
      contained in Section 9.14(a). It is understood and agreed that the enforcement
      of the obligation of the Master Servicer set forth in this Section to indemnify
      the Depositor and the Trustee as provided in this Section constitutes the sole
      remedy (other than as set forth in Section 6.14) of the Depositor and the
      Trustee, respecting a breach of the foregoing representations and warranties.
      Such indemnification shall survive any termination of the Master Servicer as
      Master Servicer hereunder, and any termination of this Agreement.

     

    Any
      cause
      of action against the Master Servicer relating to or arising out of the breach
      of any representations and warranties made in this Section shall accrue upon
      discovery of such breach by any of the Depositor, the Master Servicer, any
      NIMS
      Insurer or the Trustee or notice thereof by any one of such parties to the
      other
      parties. Notwithstanding anything in this Agreement to the contrary, the Master
      Servicer shall not be liable for special, indirect or consequential losses
      or
      damages of any kind whatsoever (including, but not limited to, lost
      profits).

     

    (c) It
      is
      understood and agreed that the representations and warranties of the Depositor
      set forth in Sections 2.03(a)(i) through (vi) shall survive the execution and
      delivery of this Agreement. The Depositor shall indemnify the Master Servicer
      and hold it harmless against any loss, damages, penalties, fines, forfeitures,
      legal fees and related costs, judgments, and other costs and expenses resulting
      from any claim, demand, defense or assertion based on or grounded upon, or
      resulting from, a breach of the Depositor’s representations and warranties
      contained in Sections 2.03(a)(i) through (vi) hereof. It is understood and
      agreed that the enforcement of the obligation of the Depositor set forth in
      this
      Section to indemnify the Master Servicer as provided in this Section constitutes
      the sole remedy hereunder of the Master Servicer respecting a breach by the
      Depositor of the representations and warranties in Sections 2.03(a)(i) through
      (vi) hereof.

     

    
      
        
        

      

      
        -135-

        
          

        

      

      
        
        

      

    

     

    Any
      cause
      of action against the Depositor relating to or arising out of the breach of
      the
      representations and warranties made in Sections 2.03(a)(i) through (vi) hereof
      shall accrue upon discovery of such breach by either the Depositor or the Master
      Servicer or notice thereof by any one of such parties to the other
      parties.

     

    Section
      9.15. Opinion

     

    On
      or
      before the Closing Date, the Master Servicer shall cause to be delivered to
      the
      Depositor, the Seller and the Trustee one or more Opinions of Counsel, dated
      the
      Closing Date, in form and substance reasonably satisfactory to the Depositor
      and
      Lehman Brothers Inc., as to the due authorization, execution and delivery of
      this Agreement by the Master Servicer and the enforceability
      thereof.

     

    Section
      9.16. Standard
      Hazard and Flood Insurance Policies

     

    For
      each
      Mortgage Loan (other than a Cooperative Loan), the Master Servicer shall
      maintain, or cause to be maintained by each Servicer, standard fire and casualty
      insurance and, where applicable, flood insurance, all in accordance with the
      provisions of this Agreement and the Servicing Agreement, as applicable. It
      is
      understood and agreed that such insurance shall be with insurers meeting the
      eligibility requirements set forth in the applicable Servicing Agreement and
      that no earthquake or other additional insurance is to be required of any
      Mortgagor or to be maintained on property acquired in respect of a defaulted
      loan, other than pursuant to such applicable laws and regulations as shall
      at
      any time be in force and as shall require such additional
      insurance.

     

    Pursuant
      to Section 4.01, any amounts collected by the Master Servicer, or by any
      Servicer, under any insurance policies maintained pursuant to this Section
      9.16
      or the applicable Servicing Agreement (other than amounts to be applied to
      the
      restoration or repair of the property subject to the related Mortgage or
      released to the Mortgagor in accordance with such Servicing Agreement) shall
      be
      deposited into the Collection Account, subject to withdrawal pursuant to Section
      4.02. Any cost incurred by the Master Servicer or any Servicer in maintaining
      any such insurance if the Mortgagor defaults in its obligation to do so shall
      be
      added to the amount owing under the Mortgage Loan where the terms of the
      Mortgage Loan so permit; provided, however, that the addition of any such cost
      shall not be taken into account for purposes of calculating the distributions
      to
      be made to Certificateholders and shall be recoverable by the Master Servicer
      or
      such Servicer pursuant to Section 4.02.

     

    Section
      9.17. Presentment
      of Claims and Collection of Proceeds

     

    The
      Master Servicer shall cause each Servicer (to the extent provided in the
      applicable Servicing Agreement) to, prepare and present on behalf of the Trustee
      and the Certificateholders all claims under the Insurance Policies with respect
      to the Mortgage Loans, and take such actions (including the negotiation,
      settlement, compromise or enforcement of the insured’s claim) as shall be
      necessary to realize recovery under such policies. Any proceeds disbursed to
      the
      Master Servicer (or disbursed to the Servicer and remitted to the Master
      Servicer) in respect of such policies or bonds shall be promptly deposited
      in
      the Collection Account or any Custodial Account upon receipt, except that any
      amounts realized that are to be applied to the repair or restoration of the
      related Mortgaged Property or released to the related Mortgagor in accordance
      with the Master Servicer’s or the applicable Servicer’s normal servicing
      procedures need not be so deposited (or remitted).

     

    
      
        
        

      

      
        -136-

        
          

        

      

      
        
        

      

    

     

    Section
      9.18. Maintenance
      of the Primary Mortgage Insurance Policies

     

    (a) The
      Master Servicer shall not take, or knowingly permit any Servicer (consistent
      with the applicable Servicing Agreement) to take, any action that would result
      in noncoverage under any applicable Primary Mortgage Insurance Policy of any
      loss which, but for the actions of such Master Servicer or such Servicer, would
      have been covered thereunder. To the extent that coverage is available, the
      Master Servicer shall use its best reasonable efforts to keep in force and
      effect, or to cause each Servicer to keep in force and effect (to the extent
      that the Mortgage Loan requires the Mortgagor to maintain such insurance),
      primary mortgage insurance applicable to each Mortgage Loan in accordance with
      the provisions of this Agreement and the applicable Servicing Agreement, as
      applicable. The Master Servicer shall not, and shall not knowingly permit any
      Servicer to, cancel or refuse to renew any such Primary Mortgage Insurance
      Policy that is in effect at the date of the initial issuance of the Certificates
      and is required to be kept in force hereunder except in accordance with the
      provisions of this Agreement and the applicable Servicing Agreement, as
      applicable.

     

    (b) The
      Master Servicer agrees, to the extent provided in the related Servicing
      Agreement, to cause each Servicer to present, on behalf of the Trustee and
      the
      Certificateholders, claims to the insurer under any Primary Mortgage Insurance
      Policies and, in this regard, to take such reasonable action as shall be
      necessary to permit recovery under any Primary Mortgage Insurance Policies
      respecting defaulted Mortgage Loans. Pursuant to Section 4.01, any amounts
      collected by the Master Servicer or any Servicer under any Primary Mortgage
      Insurance Policies shall be deposited in the Collection Account, subject to
      withdrawal pursuant to Section 4.02.

     

    Section
      9.19. Trustee
      To Retain Possession of Certain Insurance Policies and
      Documents

     

    The
      Trustee (or the Custodian) shall retain possession and custody of the originals
      of the Primary Mortgage Insurance Policies or certificate of insurance if
      applicable and any certificates of renewal as to the foregoing as may be issued
      from time to time as contemplated by this Agreement. Until all amounts
      distributable in respect of the Certificates have been distributed in full
      and
      the Master Servicer otherwise has fulfilled its obligations under this
      Agreement, the Trustee (or the Custodian) shall also retain possession and
      custody of each Mortgage File in accordance with and subject to the terms and
      conditions of this Agreement. The Master Servicer shall promptly deliver or
      cause the applicable Servicer to deliver to the Trustee (or the Custodian),
      upon
      the execution or receipt thereof the originals of the Primary Mortgage Insurance
      Policies and any certificates of renewal thereof, and such other documents
      or
      instruments that constitute portions of the Mortgage File that come into the
      possession of the Master Servicer or a Servicer from time to time.

     

    
      
        
        

      

      
        -137-

        
          

        

      

      
        
        

      

    

     

    Section
      9.20. Realization
      Upon Defaulted Mortgage Loans

     

    (a) The
      Master Servicer shall use its reasonable best efforts to, or to cause the
      applicable Servicer to, foreclose upon, repossess or otherwise comparably
      convert the ownership of Mortgaged Properties securing such of the Mortgage
      Loans as come into and continue in default and as to which no satisfactory
      arrangements can be made for collection of delinquent payments, all in
      accordance with the applicable Servicing Agreement. Alternatively, the Master
      Servicer may take, or authorize the applicable Servicer to take, other actions
      in respect of a defaulted Mortgage Loan, which may include (i) accepting a
      short
      sale (a payoff of the Mortgage Loan for an amount less than the total amount
      contractually owed in order to facilitate a sale of the Mortgaged Property
      by
      the Mortgagor) or permitting a short refinancing (a payoff of the Mortgage
      Loan
      for an amount less than the total amount contractually owed in order to
      facilitate refinancing transactions by the Mortgagor not involving a sale of
      the
      Mortgaged Property), (ii) arranging for a repayment plan or (iii) agreeing
      to a
      modification in accordance with Section 9.04. In connection with such
      foreclosure or other conversion or action, the Master Servicer shall, consistent
      with Section 9.18, follow such practices and procedures as it shall reasonably
      determine to be in the best interests of the Trust Fund and the
      Certificateholders and which shall be consistent with its customary practices
      in
      performing its general mortgage servicing activities; provided that the Master
      Servicer shall not be liable in any respect hereunder if the Master Servicer
      is
      acting in connection with any such foreclosure or other conversion or action
      in
      a manner that is consistent with the provisions of this Agreement. Neither
      the
      Master Servicer, nor any Servicer, shall be required to expend its own funds
      or
      incur other reimbursable charges in connection with any foreclosure, or
      attempted foreclosure which is not completed, or toward the correction of any
      default on a related senior mortgage loan, or towards the restoration of any
      property unless it shall determine (i) that such restoration and/or foreclosure
      will increase the proceeds of liquidation of the Mortgage Loan to the
      Certificateholders after reimbursement to itself for such expenses or charges
      and (ii) that such expenses and charges will be recoverable to it through
      Liquidation Proceeds or Insurance Proceeds (as provided in Section
      4.02).

     

    (b) Notwithstanding
      the foregoing provisions of this Section 9.20 or any other provision of this
      Agreement, with respect to any Mortgage Loan as to which the Master Servicer
      has
      received actual notice of, or has actual knowledge of, the presence of any
      toxic
      or hazardous substance on the related Mortgaged Property, the Master Servicer
      shall not, on behalf of the Trustee, either (i) obtain title to such Mortgaged
      Property as a result of or in lieu of foreclosure or otherwise, or (ii)
      otherwise acquire possession of, or take any other action with respect to,
      such
      Mortgaged Property, if, as a result of any such action, the Trustee, the Trust
      Fund or the Certificateholders would be considered to hold title to, to be
      a
“mortgagee-in-possession” of, or to be an “owner” or “operator” of such
      Mortgaged Property within the meaning of the Comprehensive Environmental
      Response, Compensation and Liability Act of 1980, as amended from time to time,
      or any comparable law, unless the Master Servicer has obtained the prior written
      consent of the NIMS Insurer.

     

    Section
      9.21. Compensation
      to the Master Servicer

     

    The
      Master Servicer shall be entitled to withdraw from the Collection Account,
      subject to Section 5.05, the Master Servicing Fee to the extent permitted by
      Section 4.02. Servicing compensation in the form of assumption fees, if any,
      late payment charges, as collected, if any, or otherwise (but not including
      any
      Prepayment Premium) shall be retained by the Master Servicer (or the applicable
      Servicer) and shall not be deposited in the Collection Account. If the Master
      Servicer does not retain or withdraw the Master Servicing Fee from the
      Collection Account as provided herein, the Master Servicer shall be entitled
      to
      direct the Trustee to pay the Master Servicing Fee to such Master Servicer
      by
      withdrawal from the Certificate Account to the extent that payments have been
      received with respect to the applicable Mortgage Loan. The Master Servicer
      shall
      be required to pay all expenses incurred by it in connection with its activities
      hereunder and shall not be entitled to reimbursement therefor except as provided
      in this Agreement. Pursuant to Section 4.01(e), all income and gain realized
      from any investment of funds in the Collection Account shall be for the benefit
      of the Master Servicer as compensation. The provisions of this Section 9.21
      are
      subject to the provisions of Section 6.14.

    Section
      9.22. REO
      Property

     

    (a) In
      the
      event the Trust Fund acquires ownership of any REO Property in respect of any
      Mortgage Loan, the deed or certificate of sale shall be issued to the Trustee,
      or to its nominee, on behalf of the Certificateholders. The Master Servicer
      shall use its reasonable best efforts to sell, or cause the applicable Servicer,
      to the extent provided in the related Servicing Agreement, to sell any REO
      Property as expeditiously as possible and in accordance with the provisions
      of
      this Agreement and such Servicing Agreement, as applicable, but in all events
      within the time period, and subject to the conditions set forth in Article
      X
      hereof. Pursuant to its efforts to sell such REO Property, the Master Servicer
      shall protect and conserve, or cause the applicable Servicer to protect and
      conserve, such REO Property in the manner and to such extent required by the
      related Servicing Agreement, subject to Article X hereof.

     

    (b) The
      Master Servicer shall deposit or cause to be deposited all funds collected
      and
      received by it, or recovered from the Servicer, in connection with the operation
      of any REO Property in the Collection Account.

     

    (c) The
      Master Servicer and the applicable Servicer, upon the final disposition of
      any
      REO Property, shall be entitled to reimbursement for any related unreimbursed
      Advances and other unreimbursed advances as well as any unpaid Master Servicing
      Fees or General Servicing Fees from Liquidation Proceeds received in connection
      with the final disposition of such REO Property; provided, that (without
      limitation of any other right of reimbursement that the Master Servicer or
      any
      Servicer shall have hereunder) any such unreimbursed Advances as well as any
      unpaid Master Servicing Fees or General Servicing Fees may be reimbursed or
      paid, as the case may be, prior to final disposition, out of any net rental
      income or other net amounts derived from such REO Property.

     

    (d) The
      Liquidation Proceeds from the final disposition of the REO Property, net of
      any
      payment to the Master Servicer and the applicable Servicer as provided above,
      shall be deposited in the Collection Account on or prior to the Determination
      Date in the month following receipt thereof (and the Master Servicer shall
      provide written notice to the Trustee upon such deposit) and be remitted by
      wire
      transfer in immediately available funds to the Trustee for deposit into the
      Certificate Account on the next succeeding Deposit Date.

    Section
      9.23. Notice
      to the Sponsor, the Depositor and the Trustee

     

    (a) The
      Master Servicer shall promptly notify the Trustee, the Sponsor and the Depositor
      (i) of any legal proceedings pending against the Master Servicer of the type
      described in Item 1117 (§ 229.1117) of Regulation AB.

     

    (b) On
      or
      before March 1st
      of each
      year, the Depositor shall distribute the information in Exhibit S to the Master
      Servicer. If the Master Servicer shall become at any time an affiliate of any
      of
      the parties listed on Exhibit S hereto or any of their affiliates who have
      been
      identified to the Master Servicer in writing, the Master Servicer shall notify
      the Trustee, the Sponsor and the Depositor of such affiliation by March 15
      of
      each year (but only to the extent that the Master Servicer has not previously
      notified the Trustee, the Sponsor or the Depositor of such
      affiliation.)

     

    (c) Not
      later
      than four Business Days prior to the Distribution Date of each month, the Master
      Servicer shall provide to the Trustee, the Sponsor and the Depositor notice
      of
      the occurrence of any material modifications, extensions or waivers of terms,
      fees, penalties or payments relating to the Mortgage Loans during the related
      Collection Period or that have cumulatively become material over time (Item
      1121(a)(11) of Regulation AB) along with all information, data, and materials
      related thereto as may be required to be included in the related Distribution
      Report on Form
      10-D,
      in each
      case solely as reported to the Master Servicer by the applicable Servicer.
      The
      parties to this Agreement acknowledge that the performance by the Master
      Servicer of its duties under this Section 9.23(c) related to the timely
      preparation and delivery of such information is contingent upon each applicable
      Servicer strictly observing all requirements and deadlines in the performance
      of
      their duties under their related Servicing Agreements. The Master Servicer
      shall
      have no liability for any loss, expense, damage or claim arising out of or
      with
      respect to any failure to properly prepare and/or timely deliver all such
      information where such failure results from the Master Servicer’s inability or
      failure to obtain or receive, on a timely basis, any information from any
      Servicer needed to prepare or deliver such information, which failure does
      not
      result from the Master Servicer’s own negligence, bad faith or willful
      misconduct.

     

    Section
      9.24. Reports
      to the Trustee

      nature and status thereof) and showing, for the period covered by such
      statement, the aggregate of deposits into and withdrawals from the Collection
      Account maintained by the Master Servicer. Copies of such statement shall be
      provided by the Master Servicer, upon request, to the Depositor, Attention:
      Contract Finance and to any Certificateholders (or by the Trustee at the Master
      Servicer’s expense if the Master Servicer shall fail to provide such copies to
      the Certificateholders (unless (i) the Master Servicer shall have failed to
      provide the Trustee with such statement or (ii) the Trustee shall be unaware
      of
      the Master Servicer’s failure to provide such statement)).

      such
      information has been provided to the Master Servicer by the Servicers or by
      the
      Depositor.

     

    (c) All
      information, reports and statements prepared by the Master Servicer under this

      9.25. Assessment
      of Compliance and Attestation Reports

     

    (a) Assessment
      of Compliance

     

    (i) On
      or
      before March 15th of each calendar year in which the Depositor is required
      to
      file reports with respect to the Trust Fund in accordance with the Exchange
      Act
      and the rules and regulations of the Commission, beginning with March 15, 2007,
      the Master Servicer, the Paying Agent (if other than the Trustee) and the
      Trustee, each at its own expense, shall furnish, and each such party shall
      cause
      any Servicing Function Participant engaged by it to furnish, each at its own
      expense, to the Sponsor, the Depositor, the Master Servicer and the Trustee,
      a
      report on an assessment of compliance with the Relevant Servicing Criteria
      that
      contains (A) a statement by such party of its responsibility for assessing
      compliance with the Relevant Servicing Criteria, (B) a statement that such
      party
      used the Servicing Criteria to assess compliance with the Relevant Servicing
      Criteria, (C) such party’s assessment of compliance with the Relevant Servicing
      Criteria as of and for the fiscal year covered by the Form 10-K required to
      be
      filed pursuant to Section 6.20(d), including, if there has been any material
      instance of noncompliance with the Relevant Servicing Criteria, a discussion
      of
      each such failure and the nature and status thereof, and (D) a statement that
      a
      registered public accounting firm has issued an attestation report on such
      party’s assessment of compliance with the Relevant Servicing Criteria as of and
      for such period. If the Trustee and the Paying Agent are the same party, the
      Relevant Servicing Criteria of the Paying Agent shall be included in the
      Trustee's report. The Master Servicer shall furnish to the Trustee a copy of
      each assessment of compliance provided to it by the Custodian pursuant to the
      Custodial Agreement and by each Servicer pursuant to the related Servicing
      Agreement, to the extent that the Trustee is not entitled to receive such
      assessments pursuant to each such applicable agreement.

     

    (ii) When
      the
      Master Servicer, the Paying Agent (if other than the Trustee) and the Trustee

      include the assessment (and attestation pursuant to subsection (b) of this
      Section 9.25) of each Servicing Function Participant engaged by it and shall
      indicate to the Trustee what Relevant Servicing Criteria will be addressed
      in
      any such reports prepared by any such Servicing Function Participant.


     

    (iii) Promptly
      after receipt of each report on assessment of compliance, the Trustee shall
      confirm that the assessments, taken as a whole, address all applicable Servicing
      Criteria and taken individually address the Relevant Servicing Criteria (and
      disclose the inapplicability of the Servicing Criteria not determined to be
      Relevant Servicing Criteria) for each party as set forth on Exhibit R and on
      any
      similar exhibit set forth in the applicable Servicing Agreement in respect
      of
      any Servicer, and the Custodial Agreement in respect of the Custodian, and
      shall
      notify the Depositor of any exceptions. By way of clarification and for the
      avoidance of doubt, it is acknowledged that the Trustee shall rely exclusively
      on Exhibit R to determine such applicable Servicing Criteria and Relevant
      Servicing Criteria, as the case may be, and shall not otherwise be reporting
      on
      the content of or sufficiency of such assessments.

      the Master Servicer, the Paying Agent (if other than the Trustee) and the
      Trustee shall, at its own expense, cause a firm of independent public
      accountants (who may also render other services to the Master Servicer, Paying
      Agent or Trustee), which is a member of the American Institute of Certified
      Public Accountants, to furnish to the Sponsor, the Master Servicer, the Trustee
      and the Depositor a report to the effect that such firm attests to, and reports
      on, the assessment made by such asserting party pursuant to Section 6.01(l)
      above, which report shall be made in accordance with standards for attestation
      engagements issued or adopted by the PCAOB. In addition, on or before March
      15th

    (c) The
      Trustee’s, the Paying Agent’s and the Master Servicer’s obligation to provide
      assessments of compliance and attestations under this Section 9.25 shall
      terminate upon the filing of a Form 15 suspension notice on behalf of the Trust
      Fund. After the occurrence of such event, and provided the Depositor is not
      otherwise provided with such reports or copies of such reports, the Trustee,
      the
      Paying Agent and the Master Servicer shall be obligated to provide a copy of
      such reports, by March 15 of each year, to the Depositor.

      such review, such party has fulfilled all its obligations under this Agreement,
      or such other applicable agreement in the case of an Additional Servicer, in
      all
      material respects throughout such year or portion thereof, or, if there has
      been
      a failure to fulfill any such obligation in any material respect, specifying
      each such failure known to such officer and the nature and status
      thereof.

    Section
      9.27. Merger
      or Consolidation

     

    Any
      Person into which the Master Servicer may be merged or consolidated, or any
      Person resulting from any merger, conversion, other change in form or
      consolidation to which the Master Servicer shall be a party, or any Person
      succeeding to the business of the Master Servicer, shall be the successor to
      the
      Master Servicer hereunder, without the execution or filing of any paper or
      any
      further act on the part of any of the parties hereto, anything herein to the
      contrary notwithstanding; provided, however, that the successor or resulting
      Person to the Master Servicer shall be a Person that shall be qualified and
      approved to service mortgage loans for Fannie Mae or Freddie Mac and shall
      have
      a net worth of not less than $15,000,000. Notwithstanding the foregoing, as
      a
      condition to the succession to the Master Servicer under this Agreement by
      any
      Person (i) into which the Master Servicer may be merged or consolidated, or
      (ii)
      which may be appointed as a successor to the Master Servicer, the Master

      Act).

     

    Section
      9.28. Resignation
      of Master Servicer

     

    Except
      as
      otherwise provided in Sections 9.27 and 9.29 hereof, the Master Servicer shall
      not resign from the obligations and duties hereby imposed on it unless it or
      the
      Trustee determines that the Master Servicer’s duties hereunder are no longer
      permissible under applicable law or are in material conflict by reason of
      applicable law with any other activities carried on by it and cannot be cured.
      Any such determination permitting the resignation of the Master Servicer shall
      be evidenced by an Opinion of Counsel that shall be Independent to such effect
      delivered to the Trustee and the NIMS Insurer. No such resignation shall become
      effective until a period of time not to exceed 90 days after the Trustee and
      the
      NIMS Insurer receives written notice thereof from the Master Servicer and until
      the Trustee shall have assumed, or a successor master servicer shall have been
      appointed by the Trustee, such successor master servicer being acceptable to
      the
      NIMS Insurer, and until such successor shall have assumed, the Master Servicer’s
      responsibilities and obligations under this Agreement. Notice of such
      resignation shall be given promptly by the Master Servicer and the Depositor
      to
      the Trustee.

    Section
      9.29. Assignment
      or Delegation of Duties by the Master Servicer

     

    Except
      as
      expressly provided herein, the Master Servicer shall not assign or transfer
      any
      of its rights, benefits or privileges hereunder to any other Person, or delegate
      to or subcontract with, or authorize or appoint any other Person to perform
      any
      of the duties, covenants or obligations to be performed by the Master Servicer
      hereunder; provided, however, that the Master Servicer shall have the right
      without the prior written consent of the Trustee or the Depositor to delegate
      or
      assign to or subcontract with or authorize or appoint an Affiliate of the Master
      Servicer to perform and carry out any duties, covenants or obligations to be
      performed and carried out by the Master Servicer hereunder. In no case, however,
      shall any such delegation, subcontracting or assignment to an Affiliate of
      the
      Master Servicer relieve the Master Servicer of any liability hereunder. Notice
      of such permitted assignment shall be given promptly by the Master Servicer
      to
      the Depositor and the Trustee. If, pursuant to any provision hereof, the duties
      of the Master Servicer are transferred to a successor master servicer, the
      entire amount of the Master Servicing Fees and other compensation payable to
      the
      Master Servicer pursuant hereto, including amounts payable to or permitted
      to be
      retained or withdrawn by the Master Servicer pursuant to Section 9.21 hereof,
      shall thereafter be payable to such successor master servicer.

     

    Notwithstanding
      the foregoing, for so long as reports are required to be filed with the
      Commission under the Exchange Act with respect to the Trust, the Master Servicer
      shall not utilize any Subcontractor for the performance of its duties hereunder
      if such Subcontractor would be “participating in the servicing function” within
      the meaning of Item 1122 of Regulation AB without (a) giving notice to the
      Trustee and the Depositor and (b) requiring any such Subcontractor to provide
      to
      the Master Servicer an attestation report as provided for in Section 9.25(b)
      and
      an assessment of compliance as provided in Section 9.25(a), which reports the
      Master Servicer shall include in its attestation report and assessment of
      compliance.

     

    Section
      9.30. Limitation
      on Liability of the Master Servicer and Others

     

    (a) The
      Master Servicer undertakes to perform such duties and only such duties as are
      specifically set forth in this Agreement.

     

    (b) No
      provision of this Agreement shall be construed to relieve the Master Servicer
      from liability for its own negligent action, its own negligent failure to act
      or
      its own willful misconduct; provided, however, that the duties and obligations
      of the Master Servicer shall be determined solely by the express provisions
      of
      this Agreement, the Master Servicer shall not be liable except for the
      performance of such duties and obligations as are specifically set forth in
      this
      Agreement; no implied covenants or obligations shall be read into this Agreement
      against the Master Servicer and, in absence of bad faith on the part of the
      Master Servicer, the Master Servicer may conclusively rely, as to the truth
      of
      the statements and the correctness of the opinions expressed therein, upon
      any
      certificates or opinions furnished to the Master Servicer and conforming to
      the
      requirements of this Agreement.

    (c) None
      of
      the Master Servicer, the Seller, any NIMS Insurer or the Depositor or any of
      the
      directors, officers, employees or agents of any of them shall be under any
      liability to the Trustee or the Certificateholders for any action taken or
      for
      refraining from the taking of any action in good faith pursuant to this
      Agreement, or for errors in judgment; provided, however, that this provision
      shall not protect the Master Servicer, the Seller, any NIMS Insurer or the
      Depositor or any such person against any liability that would otherwise be
      imposed by reason of willful misfeasance, bad faith or negligence in its
      performance of its duties or by reason of reckless disregard for its obligations
      and duties under this Agreement. The Master Servicer, the Seller, any NIMS
      Insurer and the Depositor and any director, officer, employee or agent of any
      of
      them shall be entitled to indemnification by the Trust Fund and will be held
      harmless against any loss, liability or expense incurred in connection with
      any
      legal action relating to this Agreement or the Certificates other than any
      loss,
      liability or expense incurred by reason of willful misfeasance, bad faith or
      negligence in the performance of his or its duties hereunder or by reason of
      reckless disregard of his or its obligations and duties hereunder. The Master
      Servicer, the Seller, any NIMS Insurer and the Depositor and any director,
      officer, employee or agent of any of them may rely in good faith on any document
      of any kind prima facie properly executed and submitted by any Person respecting
      any matters arising hereunder. The Master Servicer shall be under no obligation
      to appear in, prosecute or defend any legal action that is not incidental to
      its
      duties to master service the Mortgage Loans in accordance with this Agreement
      and that in its opinion may involve it in any expenses or liability; provided,
      however, that the Master Servicer may in its sole discretion undertake any
      such
      action that it may deem necessary or desirable in respect to this Agreement
      and
      the rights and duties of the parties hereto and the interests of the
      Certificateholders hereunder. In such event, the legal expenses and costs of
      such action and any liability resulting therefrom shall be expenses, costs
      and
      liabilities of the Trust Fund and the Master Servicer shall be entitled to
      be
      reimbursed therefor out of the Collection Account it maintains as provided
      by
      Section 4.02.

     

    Section
      9.31. Indemnification;
      Third Party Claims

     

    The
      Master Servicer agrees to indemnify the Depositor, the Sponsor, the Certificate
      Registrar, the Paying Agent and the Trustee (and each of their respective
      directors, officers, employees and agents) and hold each of them harmless
      against any and all claims, losses, penalties, fines, forfeitures, reasonable
      legal fees and related costs, judgments, and any other costs, liability, fees
      and expenses that the Depositor, the Sponsor, the Certificate Registrar, the
      Paying Agent or the Trustee may sustain arising out of or based upon (a) any
      material breach by the Master Servicer of any of its obligations hereunder,
      including particularly its obligations to provide any report under Section
      9.25(a), Section 9.25(b) or Section 9.26 or any information, data or materials
      required to be included in any Exchange Act report, provided, however, that
      in
      no event shall the Master Servicer be liable for any special, consequential,
      indirect or punitive damages pursuant to this Section 9.31, even if advised
      of
      the possibility of such damages, (b) any material misstatement or omission
      on
      any information, data, or materials provided by the Master Servicer, or (c)
      the
      negligence, bad faith or willful misconduct of the Master Servicer in connection
      with its performance hereunder. The Depositor, the Sponsor, the Certificate
      Registrar, the Paying Agent and the Trustee shall immediately notify the Master
      Servicer if a claim is made by a third party with respect to this Agreement
      or
      the Mortgage Loans entitling the Depositor, the Sponsor or the Trustee to
      indemnification hereunder, whereupon the Master Servicer shall assume the
      defense of any such claim and pay all expenses in connection therewith,
      including counsel fees, and promptly pay, discharge and satisfy any judgment
      or
      decree which may be entered against it or them in respect of such claim. This
      indemnification shall survive the termination of this Agreement or the
      termination of the Master Servicer as a party to this Agreement.

    Section
      9.32. Special
      Servicing of Delinquent Mortgage Loans

     

    If
      permitted under the terms of any Servicing Agreement, the Seller may appoint,
      pursuant to the terms of such Servicing Agreement and with the written consent
      of the Depositor, the Master Servicer, the Trustee and the NIMS Insurer, a
      Special Servicer to special service any Distressed Mortgage Loans. Any
      applicable Termination Fee related to the termination of the Servicer and the
      appointment of any Special Servicer shall be paid by the Seller. Any fees paid
      to any such Special Servicer shall not exceed the General Servicing Fee
      Rate.

     

    Section
      9.33. Allocation
      to Related Mortgage Pool

     

    Payments
      described in this Article IX made from the Trust Fund shall be allocated and
      limited to collections or other recoveries on the related Mortgage Pool or
      Mortgage Pools and shall be accounted for in such manner.

    REMIC
      ADMINISTRATION

     

    Section
      10.01. REMIC
      Administration

     

    (a) REMIC
      elections as set forth in the Preliminary Statement and this Section 10.01
      shall
      be made on Forms 1066 or other appropriate federal tax or information return
      for
      the taxable year ending on the last day of the calendar year in which the
      Certificates are issued. The regular interests and residual interest in each
      REMIC shall be as designated in the Preliminary Statement and this Section
      10.01. For purposes of such designations, the interest rate of any regular
      interest that is computed by taking into account the weighted average of the
      Net
      Mortgage Rates of the Mortgage Loans shall be reduced to take into account
      any
      expense paid by the Trust to the extent that (i) such expense was not taken
      into
      account in computing the Net Mortgage Rate of any Mortgage Loan or any Net
      Funds
      Cap, (ii) such expense does not constitute an “unanticipated expense” of a REMIC
      within the meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii) and (iii)
      the amount of such expense was not taken into account in computing the interest
      rate of a more junior Class of regular interests.

     

    (b) The
      Closing Date is hereby designated as the “Startup Day” of each REMIC within the
      meaning of section 860G(a)(9) of the Code. The latest possible maturity date
      for
      purposes of Treasury Regulation 1.860G-1(a)(4) will be the Latest Possible
      Maturity Date.

     

    (c) The
      Trustee shall represent the Trust Fund in any administrative or judicial
      proceeding relating to an examination or audit by any governmental taxing
      authority with respect thereto. The Trustee shall pay any and all tax related
      expenses (not including taxes) of each REMIC and Grantor Trust, including but
      not limited to any professional fees or expenses related to audits or any
      administrative or judicial proceedings with respect to such REMIC or Grantor
      Trust that involve the Internal Revenue Service or state tax authorities, but
      only to the extent that (i) such expenses are ordinary or routine expenses,
      including expenses of a routine audit but not expenses of litigation (except
      as
      described in (ii)); or (ii) such expenses or liabilities (including taxes and
      penalties) are attributable to the negligence or willful misconduct of the
      Trustee in fulfilling its duties hereunder (including its duties as tax return
      preparer). The Trustee shall be entitled to reimbursement from the Certificate
      Account of the expenses to the extent (x) provided in clause (i) above and
      (y)
      with respect to each REMIC, such expenses are “unanticipated expenses” within
      the meaning of Treasury Regulation Section 1.860G-1(b)(3)(ii). Any reimbursement
      described in the preceding sentence shall be allocated and limited to
      collections or other recoveries on the related Mortgage Pool and shall be
      accounted for in such manner.

     

    
      
        
        

      

      
        -146-

        
          

        

      

      
        
        

      

    

     

    (d) The
      Trustee shall prepare, the Trustee shall sign, and the Trustee will file, all
      of
      each REMIC’s federal and state tax and information returns as such REMIC’s
      direct representative. The Trustee shall prepare, sign and file all of the
      tax
      or information returns in respect of each Grantor Trust. The Trustee shall
      comply with such requirement by filing Form 1041. The expenses of preparing
      and
      filing such returns shall be borne by the Trustee.

     

    (e) The
      Trustee or its designee shall perform on behalf of the Trust Fund and each
      REMIC
      and Grantor Trust all reporting and other tax compliance duties that are the
      responsibility of the Trust Fund or such REMIC or Grantor Trust under the Code,
      the REMIC Provisions, or other compliance guidance issued by the Internal
      Revenue Service or any state or local taxing authority. Among its other duties,
      if required by the Code, the REMIC Provisions, or other such guidance, the
      Trustee shall provide (i) to the Treasury or other governmental authority such
      information as is necessary for the application of any tax relating to the
      transfer of a Residual Certificate to any disqualified person or organization
      pursuant to Treasury Regulation 1.860E-2(a)(5) and any person designated in
      Section 860E(e)(3) of the Code and (ii) to the Certificateholders such
      information or reports as are required by the Code or REMIC
      Provisions.

     

    (f) The
      Trustee, the Master Servicer and the Holders of Certificates shall take any
      action, within their respective control and scope of their duties, or cause
      any
      REMIC to take any action necessary to create or maintain the status of any
      REMIC
      as a REMIC under the REMIC Provisions and shall assist each other as necessary
      to create or maintain such status. Neither the Trustee, the Master Servicer
      nor
      the Holder of any Residual Certificate shall knowingly take any action, cause
      any REMIC to take any action or fail to take (or fail to cause to be taken)
      any
      action, within their respective control and scope of their duties, that, under
      the REMIC Provisions, if taken or not taken, as the case may be, could result
      in
      an Adverse REMIC Event unless the Trustee, the NIMS Insurer and the Master
      Servicer have received an Opinion of Counsel (at the expense of the party
      seeking to take such action) to the effect that the contemplated action will
      not
      result in an Adverse REMIC Event. In addition, prior to taking any action with
      respect to any REMIC or the assets therein, or causing any REMIC to take any
      action, which is not expressly permitted under the terms of this Agreement,
      any
      Holder of a Residual Certificate will consult with the Trustee, the NIMS
      Insurer, the Master Servicer or their respective designees, in writing, with
      respect to whether such action could cause an Adverse REMIC Event to occur
      with
      respect to any REMIC, and no such Person shall take any such action or cause
      any
      REMIC to take any such action as to which the Trustee, the NIMS Insurer or
      the
      Master Servicer has advised it in writing that an Adverse REMIC Event could
      occur.

     

    (g) Each
      Holder of a Residual Certificate shall pay when due any and all taxes imposed
      on
      the related REMIC by federal or state governmental authorities. To the extent
      that such taxes are not paid by a Residual Certificateholder, the Trustee shall
      pay any remaining REMIC taxes out of current or future amounts otherwise
      distributable to the Holder of the Residual Certificate in any such REMIC or,
      if
      no such amounts are available, out of other amounts held in the Collection
      Account, and shall reduce amounts otherwise payable to holders of regular
      interests in any such REMIC, as the case may be.

     

    
      
        
        

      

      
        -147-

        
          

        

      

      
        
        

      

    

     

    (h) The
      Trustee shall, for federal income tax purposes, maintain books and records
      with
      respect to each REMIC on a calendar year and on an accrual basis.

     

    (i) No
      additional contributions of assets shall be made to any REMIC, except as
      expressly provided in this Agreement with respect to Qualifying Substitute
      Mortgage Loans.

     

    (j) Neither
      the Trustee nor the Master Servicer shall enter into any arrangement by which
      any REMIC will receive a fee or other compensation for services.

     

    (k) Upon
      the
      request of any Rating Agency or any NIMS Insurer, the Trustee shall deliver
      an
      Officer’s Certificate to the Rating Agency and to the NIMS Insurer stating,
      without regard to any actions taken by any party other than the Trustee, the
      Trustee’s compliance with provisions of this Section 10.01.

     

    (l) The
      Class
      P Certificates shall be neither regular interests nor residual interests in
      any
      REMIC created hereunder. It is the intention of the parties hereto that the
      segregated pool of assets consisting of any collections of Prepayment Premiums
      related to the Mortgage Loans distributable to the Class P Certificates shall
      constitute a grantor trust for federal income tax purposes. The Trustee, by
      its
      execution and delivery hereof, acknowledges the assignment to it of the rights
      to receive such Prepayment Premiums and declares that it holds and will hold
      such assets in trust for the exclusive use and benefit of all present and future
      Holders of the Class P Certificates. The rights of Holders of the Class P
      Certificates to receive distributions from the proceeds of such Prepayment
      Premiums, and all ownership interests of such Holders in and to such
      distributions, shall be as set forth in this Agreement.

     

    (m) REMIC
      1
      shall consist of all of the assets of the Trust Fund (other than (i) the Lower
      Tier Interests, (ii) the grantor trusts described in Section 10.01 hereof,
      (iii)
      the Basis Risk Reserve Fund, (iv) the rights to receive Prepayment Premiums
      distributable to the Class P Certificates, (v) the Class X Account and (vi)
      the
      assets of the Grantor Trusts established pursuant to Section 5.02(h). The REMIC
      1 Regular Interests shall be designated as the regular interests in REMIC 1,
      and
      the Class LT1-R Interest shall be designated as the sole class of residual
      interest in REMIC 1. Each of the REMIC 1 Regular Interests shall have the
      characteristics set forth in the Preliminary Statement.

     

    The
      assets of REMIC 2 shall be the REMIC 1 Regular Interests. The REMIC 2 Regular
      Interests shall be designated as the regular interests in REMIC 2 and the
      Residual Interest shall be designated as the sole class of residual interest
      in
      REMIC 2. For federal income tax purposes, the interest rate on each REMIC 2
      Regular Interest (other than the Uncertificated Class X Interest) shall be
      subject to a cap equal to the REMIC Pass-Through Rate.

     

    
      
        
        

      

      
        -148-

        
          

        

      

      
        
        

      

    

     

    The
      beneficial ownership of the Class LT1-R Interest and the Residual Interest
      shall
      be represented by the Class R Certificate. Neither the Class LT1-R Interest
      nor
      the Residual Interest shall have a principal balance or bear
      interest.

     

    (n) It
      is
      intended that the rights of each Class of LIBOR Certificates to receive payments
      in respect of Excess Interest shall be treated as a right in interest rate
      cap
      contracts written by the holders of the Class X Certificates in favor of the
      holders of each Class of the LIBOR Certificates and such shall be accounted
      for
      as property held separate and apart from the regular interests in REMIC 2 held
      by the holders of the LIBOR Certificates. This provision is intended to satisfy
      the requirements of Treasury Regulations Section 1.860G-2(i) for the treatment
      of property rights coupled with REMIC interests to be separately respected
      and
      shall be interpreted consistently with such regulation. On each Distribution
      Date, to the extent that any of the LIBOR Certificates receive payments in
      respect of Excess Interest, such amounts, to the extent not derived from
      payments in respect of Class X Shortfalls as set forth in Section 10.01(p),
      will
      be treated as distributed by REMIC 2 to the Class X Certificates in respect
      of
      the Uncertificated Class X Interest pro
      rata
      and then
      paid to the relevant Class of LIBOR Certificates pursuant to the related
      interest cap agreement. The Trustee is hereby directed to perform its duties
      and
      obligations in accordance with this Section 10.01(n).

     

    It
      is
      intended that the rights of the Class 1-A3B Certificates to receive payments
      in
      respect of the Balance Guaranteed Cap Agreement shall be treated as a right
      in
      interest rate cap contracts written by the Cap Provider in favor of the holders
      of the Class 1-A3B Certificates and such shall be accounted for as property
      held
      separate and apart from the regular interests in REMIC 2 held by the holders
      of
      the Class 1-A3B Certificates. This provision is intended to satisfy the
      requirements of Treasury Regulations Section 1.860G-2(i) for the treatment
      of
      property rights coupled with REMIC interests to be separately respected and
      shall be interpreted consistently with such regulation. The Trustee is hereby
      directed to perform its duties and obligations in accordance with this Section
      10.01(n).

     

    (o) The
      parties hereto intend that the Uncertificated Class X Interest, the Basis Risk
      Reserve Fund, the right to receive payments in respect of Class X Shortfalls
      as
      set forth in Section 10.01(p) and the obligation of the holders of the Class
      X
      Certificates to pay amounts of Excess Interest to the holders of the LIBOR
      Certificates shall be treated as a “grantor trust” under the Code, and the
      provisions hereof shall be interpreted consistently with this intention. In
      furtherance of such intention, the Trustee shall (i) furnish or cause to be
      furnished to the holders of the Class X Certificates information regarding
      their
      allocable share, if any, of the income with respect to such grantor trust,
      (ii)
      file or cause to be filed with the Internal Revenue Service Form 1041 (together
      with any necessary attachments) and such other forms as may be applicable and
      (iii) comply with such information reporting obligations with respect to
      payments from such grantor trust to the holders of LIBOR Certificates as may
      be
      applicable under the Code. The Trustee is hereby directed to perform its duties
      and obligations in accordance with this Section 10.01(o).

     

    
      
        
        

      

      
        -149-

        
          

        

      

      
        
        

      

    

     

    (p) The
      excess, if any, of amounts payable with respect to the REMIC regular interests
      held by REMIC 2 over the amounts payable with respect to the REMIC 2 Regular
      Interests with respect to each Accrual Period shall, solely for purposes of
      the
      REMIC Provisions, be deemed earned by the Master Servicer as an additional
      fee,
      which amount shall be deemed paid by the Master Servicer to the holders of
      the
      Class X Certificates. It is intended that the rights of the holders of the
      Class
      X Certificates to receive such deemed payments (“Class X Shortfalls”) shall be
      treated as rights in respect of an interest rate cap contract written by the
      Master Servicer in favor of the holders of the Class X Certificates and shall
      be
      accounted for as property separate and apart from the REMIC regular interest
      represented by the Class X Certificates. This provision is intended to comply
      with the requirements of Treasury Regulations Section 1.860G-2(i) for the
      treatment of property rights coupled with regular interests to be separately
      respected and shall be interpreted consistently with such regulation. The
      holders of the Class X Certificates agree by their acceptance of such
      Certificates, that they will take tax reporting positions that allocate no
      more
      than a nominal value to the right to receive deemed payments in respect of
      Class
      X Shortfalls. The Master Servicer and Trustee shall agree to take tax reporting
      positions consistent with the allocations by the holders of the Class X
      Certificates of no more than a nominal value to the right to receive deemed
      payments in respect of Class X Shortfalls. For information reporting purposes,
      it will be assumed that such rights have no value. Each payment deemed made
      to
      the Class X Certificates in respect of Class X Shortfalls shall be treated
      for
      federal income tax purposes or having been paid to the Master Servicer as an
      additional servicing fee and then paid by the Master Servicer to the Holders
      of
      the Class X Certificates. The Trustee and Master Servicer agree and each holder
      or beneficial owner of a Class X Certificate agrees, by virtue of its
      acquisition of such Certificate or beneficial interest, to adopt tax reporting
      positions consistent with the payments deemed made to the Class X Certificates
      in respect of Class X Shortfalls as payments in respect of interest rate cap
      agreements written by the Master Servicer. The Trustee is hereby directed to
      perform its duties and obligations in accordance with this Section
      10.01(p).

     

    (q) Payments
      in the nature of expenses, reimbursements and indemnifications made from the
      Trust Fund shall be allocated and limited to collections or other recoveries
      on
      the related Mortgage Pool or Mortgage Pools (if applicable) and shall be
      accounted for in such manner.

     

    (r) The
      Trustee shall treat the Class X Account as an outside reserve fund within the
      meaning of Treasury Regulation 1.860G-2(h) that is owned by the Holder of the
      Class C Certificates and that is not an asset of any REMIC.

     

    (s) On
      each
      Distribution Date, the Trustee shall first pay or charge as an expense of REMIC
      1 all expenses of the Trust Fund for such Distribution Date. All payments of
      principal and interest at the Net Mortgage Rate on each of the Mortgage Loans
      received with respect to the Mortgage Loans (net of payments in the nature
      of
      expenses, reimbursements and indemnifications related to such Mortgage Pool
      made
      from the Trust Fund (which payments shall be limited to collections or other
      recoveries on such Mortgage Loans and shall be accounted for in such manner))
      shall be paid to the REMIC 1 Regular Interests until the principal balance
      of
      all such interests have been reduced to zero and any losses allocated to such
      interests have been reimbursed. Any excess amounts shall be distributed to
      the
      Class LT1-R Interest.

      attributable to Negative Amortization) shall be allocated to the REMIC 1 Regular
      Interests pro
      rata
      based on
      the interest otherwise accrued thereon;

     

    (ii) the
      principal balance of each REMIC 1 Regular Interest shall be increased by the
      amount of interest accrued thereon (net of interest shortfalls allocated thereto
      pursuant to the immediately preceding clause (i));

     

    (iii) 50%
      of
      the cash received by REMIC 1 shall be distributed to, and 50% of losses with
      respect to the Mortgage Loans shall be allocated to the REMIC 1-II Marker
      Classes and the Class LT1-XII Interest in reduction of their principal amounts
      as follows:

     

    first,
      to each
      of the REMIC 1-II Marker Classes ending with the designation “B”, so that its

      Class LT1-XII Interest, all remaining amounts; 

     

    (iv) 50%
      of
      the cash received by REMIC 1 with respect to the Mortgage Loans shall be

    (b) 50%
      of
      such increase shall be allocated among the REMIC 1-I Marker Classes and the
      Class LT1-XI Interest as follows:

     

    first,
      to each
      of the REMIC 1-I Marker Classes so that the principal balance of each such
      interest is as close as possible to 25% of the principal balance of its
      Corresponding Class; and

     

    second,
      to the
      Class LT1-XI Interest so that the principal balance of such interest is as

      the Trustee shall account for all distributions with respect to a Class of

      interest in REMIC 2 corresponding to such Class as amounts paid or received
      (as
      appropriate) pursuant to the interest rate cap contracts or notional principal
      contracts provided for in this Section. In no event shall any such amounts
      be
      treated as payments with respect to a “regular interest” in a REMIC within the
      meaning of Code Section 860G(a)(1).

      a
      copy of which shall be provided to any NIMS Insurer, that such disposition,
      acquisition, substitution, or acceptance will not (a) result in an Adverse
      REMIC
      Event, (b) affect the distribution of interest or principal on the Certificates,
      or (c) result in the encumbrance of the assets transferred or assigned to the

    Section
      10.03. Indemnification
      with Respect to Certain Taxes and Loss of REMIC Status

     

    Upon
      the
      occurrence of an Adverse REMIC Event due to the negligent performance by the
      Trustee of its duties and obligations set forth herein, the Trustee shall
      indemnify the NIMS Insurer, the Holder of the related Residual Certificate
      or
      the Trust Fund, as applicable, against any and all losses, claims, damages,
      liabilities or expenses (“Losses”) resulting from such negligence; provided,
      however, that the Trustee shall not be liable for any such Losses attributable
      to the action or inaction of the Master Servicer, the Depositor, the Class
      X or
      Class R Certificateholder, as applicable, nor for any such Losses resulting
      from
      misinformation provided by the Holder of such Residual Certificate on which
      the
      Trustee has relied. The foregoing shall not be deemed to limit or restrict
      the
      rights and remedies of the Holder of such Residual Certificate now or hereafter
      existing at law or in equity. Notwithstanding the foregoing, however, in no
      event shall the Trustee have any liability (1) for any action or omission that
      is taken in accordance with and in compliance with the express terms of, or
      which is expressly permitted by the terms of, this Agreement or any Servicing
      Agreement, (2) for any Losses other than arising out of a negligent performance
      by the Trustee of its duties and obligations set forth herein, and (3) for
      any
      special or consequential damages to Certificateholders (in addition to payment
      of principal and interest on the Certificates).

     

    Section
      10.04. REO
      Property

     

    (a) Notwithstanding
      any other provision of this Agreement, the Master Servicer, acting on behalf
      of
      the Trustee hereunder, shall not, except to the extent provided in the
      applicable Servicing Agreement, knowingly permit any Servicer to, rent, lease,
      or otherwise earn income on behalf of any REMIC with respect to any REO Property
      which might cause an Adverse REMIC Event unless the Master Servicer has advised,
      or has caused such Servicer to advise, the Trustee in writing to the effect
      that, under the REMIC Provisions, such action would not result in an Adverse
      REMIC Event.

     

    (b) The
      Master Servicer shall cause the applicable Servicer (to the extent provided
      in
      the related Servicing Agreement) to make reasonable efforts to sell any REO
      Property for its fair market value. In any event, however, the Master Servicer
      shall, or shall cause the applicable Servicer to, dispose of any REO Property
      within three years of its acquisition by the Trust Fund unless the Master
      Servicer has received a grant of extension from the Internal Revenue Service
      to
      the effect that, under the REMIC Provisions, the REMIC may hold REO Property
      for
      a longer period without causing an Adverse REMIC Event. If the Master Servicer
      has received such an extension, then the Master Servicer, acting on the
      Trustee’s behalf hereunder, shall, or shall cause the Servicer to, continue to
      attempt to sell the REO Property for its fair market value for such period
      longer than three years as such extension permits (the “Extended Period”). If
      the Master Servicer has not received such an extension and the Master Servicer
      or the applicable Servicer, acting on behalf of the Trustee hereunder, is unable
      to sell the REO Property within 33 months after its acquisition by the Trust
      Fund or if the Master Servicer has received such an extension, and the Master
      Servicer or such Servicer is unable to sell the REO Property within the period
      ending three months before the close of the Extended Period, the Master Servicer
      shall cause such Servicer, before the end of the three year period or the
      Extended Period, as applicable, to (i) purchase such REO Property at a price
      equal to the REO Property’s fair market value or (ii) auction the REO Property
      to the highest bidder (which may be such Servicer) in an auction reasonably
      designed to produce a fair price prior to the expiration of the three year
      period or the Extended Period, as the case may be.

    Section
      11.01. Binding
      Nature of Agreement; Assignment

     

    This
      Agreement shall be binding upon and inure to the benefit of the parties hereto
      and their respective successors and permitted assigns.

     

    Section
      11.02. Entire
      Agreement

     

    This
      Agreement contains the entire agreement and understanding among the parties
      hereto with respect to the subject matter hereof, and supersedes all prior
      and
      contemporaneous agreements, understandings, inducements and conditions, express
      or implied, oral or written, of any nature whatsoever with respect to the
      subject matter hereof. The express terms hereof control and supersede any course
      of performance and/or usage of the trade inconsistent with any of the terms
      hereof.

     

    Section
      11.03. Amendment

     

    (a) This
      Agreement may be amended from time to time by the Depositor, the Master Servicer
      and the Trustee, with the consent of the NIMS Insurer and without notice to
      or
      the consent of any of the Holders, (i) to cure any ambiguity, (ii) to cause
      the
      provisions herein to conform to or be consistent with or in furtherance of
      the
      statements made with respect to the Certificates, the Trust Fund or this
      Agreement in any Offering Document, or to correct or supplement any provision
      herein which may be inconsistent with any other provisions herein or with the
      provisions of any Servicing Agreement, (iii) to make any other provisions with
      respect to matters or questions arising under this Agreement or (iv) to add,
      delete, or amend any provisions to the extent necessary or desirable to comply
      with any requirements imposed by the Code and the REMIC Provisions. No such
      amendment effected pursuant to the preceding sentence shall, as evidenced by
      an
      Opinion of Counsel, result in an Adverse REMIC Event, nor shall such amendment
      effected pursuant to clause (iii) of such sentence adversely affect in any
      material respect the interests of any Holder. Prior to entering into any
      amendment without the consent of Holders pursuant to this paragraph, the Trustee
      and the NIMS Insurer shall be provided with an Opinion of Counsel addressed
      to
      the Trustee and the NIMS Insurer (at the expense of the party requesting such
      amendment) to the effect that such amendment is permitted under this Section.
      Any such amendment shall be deemed not to adversely affect in any material
      respect any Holder, if the Trustee and the NIMS Insurer receive written
      confirmation from each Rating Agency that such amendment will not cause such
      Rating Agency to reduce the then current rating assigned to the Certificates
      (and any Opinion of Counsel requested by the Trustee in connection with any
      such
      amendment may rely expressly on such confirmation as the basis
      therefor).

      (b) This
        Agreement may also be amended from time to time by the Depositor, the Master
        Servicer, the NIMS Insurer and the Trustee, with the consent of the Holders
        of
        not less than 66 2/3% of the Class Principal Amount or Class Notional Amount
        (or
        Percentage Interest) of each Class of Certificates (other than the Grantor
        Trust
        Certificates) affected thereby, for the purpose of adding any provisions
        to or
        changing in any manner or eliminating any of the provisions of this Agreement
        or
        of modifying in any manner the rights of the Holders; provided, however,
        that no
        such amendment shall be made unless the Trustee receives an Opinion of Counsel
        addressed to the Trustee and the NIMS Insurer, at the expense of the party
        requesting the change, that such change will not cause an Adverse REMIC Event;
        and provided further, that no such amendment may (i) reduce in any manner
        the
        amount of, or delay the timing of, payments received on Mortgage Loans which
        are
        required to be distributed on any Certificate, without the consent of the
        Holder
        of such Certificate or (ii) reduce the aforesaid percentages of Class Principal
        Amount (or Percentage Interest) of Certificates of each Class, the Holders
        of
        which are required to consent to any such amendment without the consent of
        the
        Holders of 100% of the Class Principal Amount or Class Notional Amount (or
        Percentage Interest) of each Class of Certificates affected thereby. For
        purposes of this paragraph, references to “Holder” or “Holders” shall be deemed
        to include, in the case of any Class of Book-Entry Certificates, the related
        Certificate Owners.

       

      (c) Promptly
        after the execution of any such amendment, the Trustee shall furnish written
        notification of the substance of such amendment to each Holder, the NIMS
        Insurer, the Depositor and to the Rating Agencies.

       

      (d) It
        shall
        not be necessary for the consent of Holders under this Section 11.03 to approve
        the particular form of any proposed amendment, but it shall be sufficient
        if

      Section
        11.15. Transfer
        of Servicing

       

      The
        Seller agrees that it shall provide written notice to the Master Servicer,
        the
        NIMS Insurer and the Trustee thirty days prior to any proposed transfer or
        assignment by the Seller of its rights under any Servicing Agreement or of
        the
        servicing thereunder from time to time with respect to any Mortgage Loan
        or
        group of Mortgage Loans, or delegation of its rights or duties thereunder
        or any
        portion thereof to any other Person other than the initial Servicer under
        such
        Servicing Agreement; provided, however, that the Seller shall not be required
        to
        provide prior notice of any transfer of servicing that occurs within three
        months following the Closing Date to an entity that is a Servicer on the
        Closing
        Date. In addition, the ability of the Seller to transfer or assign its rights
        and delegate its duties under a Servicing Agreement or to transfer the servicing
        thereunder, from time to time with respect to any Mortgage Loan or group
        of
        Mortgage Loans, to a successor servicer shall be subject to the following
        conditions:

       

      (i) Satisfaction
        of the conditions to such transfer as set forth in the Servicing Agreement
        including, without limitation, receipt of written consent of the Master Servicer
        to such transfer;

       

      (ii) Receipt
        of the written consent of any NIMS Insurer, such consent not to be unreasonably
        withheld;

       

      (iii) Such
        successor servicer must be qualified to service loans for Fannie Mae or Freddie
        Mac, and must be a member in good standing of MERS;

       

      (iv) Such
        successor servicer must satisfy the seller/servicer eligibility standards
        in the
        applicable Servicing Agreement, exclusive of any experience in mortgage loan
        origination and must be reasonably acceptable to the Master Servicer, whose
        approval shall not be unreasonably withheld;

       

      (v) Such
        successor servicer must execute and deliver to the Trustee and the Master
        Servicer an agreement, in form and substance reasonably satisfactory to the
        Trustee and the Master Servicer, that contains an assumption by such successor
        servicer of the due and punctual performance and observance of each covenant
        and
        condition to be performed and observed by the applicable Servicer under the
        related Servicing Agreement or such successor servicer shall execute and
        deliver
        to the Trustee and the Master Servicer a servicing agreement which contains
        customary and reasonable servicing provisions and which will not cause either
        Rating Agency to qualify, withdraw or downgrade the then-current rating of
        any
        of the Certificates or, (i) in the case of a transfer of servicing to a party
        that is already a Servicer pursuant to this Agreement, an agreement to add
        the
        related Mortgage Loans to the Servicing Agreement already in effect with
        such
        Servicer and (ii) in the case of a transfer of servicing to a Special Servicer
        pursuant to Section 9.32 herein, a special servicing agreement in the form
        of
        that attached to the applicable Servicing Agreement;

       

      
        
          
          

        

        
          -160-

          
            

          

        

        
          
          

        

      

       

      (vi) If
        the
        successor servicer is not a Servicer of Mortgage Loans at the time of the
        transfer, there must be delivered to the Trustee and the Master Servicer
        a
        letter from each Rating Agency to the effect that such transfer of servicing
        will not result in a qualification, withdrawal or downgrade of the then-current
        rating of any of the Certificates; and

       

      (vii) The
        Seller shall, at its cost and expense, take such steps, or cause the
        transferring Servicer to take such steps, as may be necessary or appropriate
        to
        effectuate and evidence the transfer of the servicing of the specified Mortgage
        Loans to such successor or replacement servicer, including, but not limited
        to,
        the following: (A) to the extent required by the terms of the Mortgage Loans
        and
        by applicable federal and state laws and regulations, the Seller shall cause
        the
        prior Servicer to timely mail to each obligor under a Mortgage Loan any required
        notices or disclosures describing the transfer of servicing of the Mortgage
        Loans to the successor or replacement servicer; (B) prior to the effective
        date
        of such transfer of servicing, the Seller shall cause the prior Servicer
        to
        transmit to any related insurer notification of such transfer of servicing;
        (C)
        on or prior to the effective date of such transfer of servicing, the Seller
        shall cause the prior Servicer to deliver to the successor or replacement
        servicer all Mortgage Loan Documents and any related records or materials;
        (D)
        on or prior to the effective date of such transfer of servicing, the Seller
        shall cause the prior Servicer to transfer to the successor or replacement
        servicer, or, if such transfer occurs after a Servicer Remittance Date but
        before the next succeeding Deposit Date, to the Trustee, all funds held by
        the
        prior Servicer in respect of the Mortgage Loans; (E) on or prior to the
        effective date of such transfer of servicing, the Seller shall cause the
        prior
        Servicer to, after the effective date of the transfer of servicing to the
        successor or replacement servicer, continue to forward to such successor
        or
        replacement servicer, within one Business Day of receipt, the amount of any
        payments or other recoveries received by the prior Servicer, and to notify
        the
        successor or replacement servicer of the source and proper application of
        each
        such payment or recovery; and (F) the Seller shall cause the prior Servicer
        to,
        after the effective date of transfer of servicing to the successor or
        replacement servicer, continue to cooperate with the successor or replacement
        servicer to facilitate such transfer in such manner and to such extent as
        the
        successor or replacement servicer may reasonably request. Notwithstanding
        the
        foregoing, the prior Servicer shall be obligated to perform the items listed
        above to the extent provided in the applicable Servicing Agreement.

    [NAME
      OF
      OFFICER], _________________ being first duly sworn, deposes and

      plan subject to any provisions under any federal, state, local, non-U.S. or
      other laws or regulations that are substantively similar to the foregoing
      provisions of ERISA or the Code (collectively, a “Plan”), and is not directly or
      indirectly acquiring a Residual Certificate for, on behalf of or with any assets
      of any such Plan.

     

    5.  That
      the
      Purchaser hereby acknowledges that under the terms of the Trust Agreement (the
      “Agreement”) by and among Structured Asset Securities Corporation, as Depositor,

      Association, as Trustee, dated as of December 1, 2006, relating to GreenPoint
      Mortgage Funding Trust Mortgage Pass-Through Certificates, Series 2006-AR8,
      no
      transfer of the Residual Certificates shall be permitted to be made to any
      person unless the Depositor and Trustee have received a certificate from such
      transferee containing the representations in paragraphs 3 and 4
      hereof.

     

    
      
        
        

      

      
        D-1-1

        
          

        

      

      
        
        

      

       

    

    6.  That
      the
      Purchaser does not hold REMIC residual securities as nominee to facilitate
      the
      clearance and settlement of such securities through electronic book entry
      changes in accounts of participating organizations (such entity, a “Book-Entry
      Nominee”).

     

    7.  That
      the
      Purchaser does not have the intention to impede the assessment or collection
      of
      any federal, state or local taxes legally required to be paid with respect
      to
      such Residual Certificate, and that the Purchaser has provided financial
      statements or other financial information requested by the transferor in
      connection with the transfer of the Residual Certificate in order to permit
      the
      transferor to assess the financial capability of the Purchaser to pay such
      taxes.

     

    8.  That
      the
      Purchaser will not transfer a Residual Certificate to any person or entity
      (i)
      as to which the Purchaser has actual knowledge that the requirements set forth
      in paragraph 3, paragraph 6 or paragraph 10 hereof are not satisfied or that
      the
      Purchaser has reason to believe does not satisfy the requirements set forth
      in
      paragraph 7 hereof, and (ii) without obtaining from the prospective Purchaser
      an
      affidavit substantially in this form and providing to the Trustee a written
      statement substantially in the form of Exhibit D-2 to the
      Agreement.

     

    9.  That
      the
      Purchaser understands that, as the holder of a Residual Certificate, the
      Purchaser may incur tax liabilities in excess of any cash flows generated by
      the
      interest and that it intends to pay taxes associated with holding such Residual
      Certificate as they become due.

     

    10.  That
      the
      Purchaser (i) is not a Non U.S. Person or (ii) is a Non U.S. Person that holds
      a
      Residual Certificate in connection with the conduct of a trade or business
      within the United States and has furnished the transferor and the Trustee with
      an effective Internal Revenue Service Form W-8ECI (Certificate of Foreign
      Person’s Claim for Exemption From Withholding on Income Effectively Connected
      With the Conduct of a Trade or Business in the United States) or successor
      form
      at the time and in the manner required by the Code or (iii) is a Non U.S. Person
      that has delivered to both the transferor and the Trustee an opinion of a
      nationally recognized tax counsel to the effect that the transfer of such
      Residual Certificate to it is in accordance with the requirements of the Code
      and the regulations promulgated thereunder and that such transfer of a Residual
      Certificate will not be disregarded for federal income tax purposes. “Non U.S.
      Person” means an individual, corporation, partnership or other person other than
      (i) a citizen or resident of the United States; (ii) a corporation, partnership
      or other entity created or organized in or under the laws of the United States
      or any state thereof, including for this purpose, the District of Columbia;
      (iii) an estate that is subject to U.S. federal income tax regardless of the
      source of its income; (iv) a trust if a court within the United States is able
      to exercise primary supervision over the administration of the trust and one
      or
      more United States trustees have authority to control all substantial decisions
      of the trust; and, (v) to the extent provided in Treasury regulations, certain
      trusts in existence on August 20, 1996 that are treated as United States persons
      prior to such date and elect to continue to be treated as United States
      persons.

     

    
      
        
        

      

      
        D-1-2

        
          

        

      

      
        
        

      

       

    

    11.  That
      the
      Purchaser agrees to such amendments of the Trust Agreement as may be required
      to
      further effectuate the restrictions on transfer of any Residual Certificate
      to
      such a “disqualified organization,” an agent thereof, a Book Entry Nominee, or a
      person that does not satisfy the requirements of paragraph 7 and paragraph
      10
      hereof.

     

    12.  That
      the
      Purchaser consents to the designation of the Trustee as its agent to act as

      believe that the Transferee has the intention to impede the assessment or
      collection of any federal, state or local taxes legally required to be paid

      a

    In

      GreenPoint Mortgage Funding Trust Mortgage Pass Through Certificates, Series
      2006-AR8 (the “Privately Offered Certificates”) of the Structured Asset
      Securities Corporation (the “Depositor”), we confirm that:

     

    
      
        	(1)	
                We
                  understand that the Privately Offered Certificates have not been,
                  and will
                  not be, registered under the Securities Act of 1933, as amended
                  (the
                  “Securities Act”), and may not be sold except as permitted in the
                  following sentence. We agree, on our own behalf and on behalf of
                  any
                  accounts for which we are acting as hereinafter stated, that if

                  or the
                  last day on which such Privately Offered Certificates are owned
                  by the

                  Rule 144A under the Securities Act) in accordance with Rule 144A
                  under the

        	(2)	
                We
                  understand that, in connection with any proposed resale of any
                  Privately
                  Offered Certificates to an Institutional Accredited Investor, we
                  will be

                  from

                We
                  are acquiring the Privately Offered Certificates for investment
