    This
      TRUST AGREEMENT, dated as of March 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 (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 and
      the
      Swap Counterparty. 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
      Swap Agreement, (ii) the Supplemental Interest Trust, (iii) the Basis Risk
      Reserve Fund, (iv) the Capitalized Interest Account, (v) the rights to receive
      Prepayment Premiums distributable to the Class P Certificates, (vi) the Lower
      Tier Interests and (vii) the Class X Account) be treated for federal income
      tax
      purposes as comprising three real estate mortgage investment conduits (each
      a
“REMIC” or, in the alternative, the “SWAP REMIC,” “REMIC 1” and “REMIC 2”). Each
      Certificate (other than the Class C, Class R and Class P Certificates)
      represents ownership of one or more regular interests in REMIC 2 for purposes
      of
      the REMIC Provisions. In addition, each Offered Certificate represents (i)
      the
      right to receive payments with respect to Excess Interest and (ii) the
      obligation to make payments in respect of Class I Shortfalls. The Class R
      Certificate represents ownership of the sole Class of residual interest in
      each
      of the SWAP REMIC, REMIC 1 and REMIC 2 for purposes of the REMIC
      Provisions.

     

    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 several
      Classes of uncertificated SWAP REMIC Regular Interests and each such SWAP REMIC
      Regular Interest is hereby designated as a regular interest in the SWAP REMIC.
      The SWAP REMIC shall hold as its assets the property of the Trust Fund other
      than (i) the Capitalized Interest Account, (ii) the Lower Tier Interests, (iii)
      the Basis Risk Reserve Fund, (iv) the Swap Agreement, (v) the Supplemental
      Interest Trust, (vi) the rights to receive Prepayment Premiums distributable
      to
      the Class P Certificates and (vii) the Class X Account.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

     

    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.

              The
                interest rate with respect to any Distribution Date (and the related
                Accrual Period) for each of these REMIC 1 Interests is a per annum
                rate
                equal to the product of (i) the weighted average of the interest
                rates on
                the SWAP REMIC Regular Interests for such Distribution Date and (ii)
                a
                fraction the numerator of which is 30 and the denominator of which
                is the
                actual number of days in the Accrual Period for the LIBOR Certificates,
                provided however, that for any Distribution Date on which the Class
                LT1-IO
                Interest is entitled to a portion of interest accruals on a SWAP
                REMIC
                Regular Interest ending with a designation “A” as described in footnote 4
                below, such weighted average shall be computed by first subjecting
                the
                rate on such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR
                for

    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.

      Trustee;

     

    (iii) with
      respect to any Mortgage Loan other than a Cooperative Loan, the original
      recorded Mortgage with evidence of recording indicated thereon and the original
      recorded power of attorney, with evidence of recording thereon. If, in
      connection with any Mortgage Loan, the Depositor cannot deliver the Mortgage
      or
      power of attorney with evidence of recording thereon on or prior to the Closing
      Date because of a delay caused by the public recording office where such
      Mortgage has been delivered for recordation or because such Mortgage or power
      of
      attorney has been lost, the Depositor shall deliver or cause to be delivered
      to
      the Trustee (or the applicable Custodian), in the case of a delay due to
      recording, a true copy of such Mortgage or power of attorney, pending delivery
      of the original thereof, together with an Officer’s Certificate of the Depositor
      certifying that the copy of such Mortgage or power of attorney delivered to
      the

      or power of attorney has been forwarded to the public recording office, or,
      in
      the case of a Mortgage or power of attorney that has been lost, a copy thereof
      (certified as provided for under the laws of the appropriate jurisdiction)
      and a
      written Opinion of Counsel delivered to the Trustee and the Depositor that
      an
      original recorded Mortgage or power of attorney is not required to enforce
      the
      Trustee’s interest in the Mortgage Loan;

     

    (iv) the
      original of each assumption, modification or substitution agreement, if any,
      relating to the Mortgage Loans, or, as to any assumption, modification or
      substitution agreement which cannot be delivered on or prior to the Closing
      Date
      because of a delay caused by the public recording office where such assumption,
      modification or substitution agreement has been delivered for recordation,
      a
      photocopy of such assumption, modification or substitution agreement, pending
      delivery of the original thereof, together with an Officer’s Certificate of the
      Depositor certifying that the copy of such assumption, modification or
      substitution agreement delivered to the Trustee (or the applicable Custodian)
      is
      a true copy and that the original of such agreement has been forwarded to the
      public recording office;

     

    (v) with
      respect to each Non-MERS Mortgage Loan, an original Assignment of Mortgage,
      in
      form and substance acceptable for recording. The related Mortgage shall be
      assigned either (A) in blank, without recourse or (B) to “U.S. Bank National
      Association, as Trustee of the Lehman XS Trust Mortgage Pass-Through
      Certificates, Series 2006-4N,” without recourse;

    (vi) if
      applicable, such original intervening assignments of the Mortgage, notice of
      transfer or equivalent instrument (each, an “Intervening Assignment”), as may be
      necessary to show a complete chain of assignment from the originator, or, in
      the
      case of an Intervening Assignment that has been lost, a written Opinion of
      Counsel delivered to the Trustee that such original Intervening Assignment
      is
      not required to enforce the Trustee’s interest in the Mortgage
      Loans;

     

    (vii) with
      respect to any Mortgage Loan other than a Cooperative Loan, the original
      mortgagee title insurance policy or attorney’s opinion of title and abstract of
      title, and, if applicable, the original Primary Mortgage Insurance Policy or
      certificate;

     

    (viii) the
      original of any security agreement, chattel mortgage or equivalent instrument
      executed in connection with the Mortgage or as to any security agreement,
      chattel mortgage or their equivalent instrument that cannot be delivered on
      or
      prior to the Closing Date because of a delay caused by the public recording
      office where such document has been delivered for recordation, a photocopy
      of
      such document, pending delivery of the original thereof, together with an
      Officer’s Certificate of the Depositor certifying that the copy of such security
      agreement, chattel mortgage or their equivalent instrument delivered to the
      Trustee (or the applicable Custodian) is a true copy and that the original
      of
      such document has been forwarded to the public recording office;

     

    (ix) with
      respect to any manufactured housing contract, any related manufactured housing
      sales contract, installment loan agreement or participation interest;
      and

     

    (x) with
      respect to any Cooperative Loan, the Cooperative Loan Documents.

     

    The
      parties hereto acknowledge and agree that the form of endorsement attached
      hereto as Exhibit B-4 is intended to effect the transfer to the Trustee, for
      the
      benefit of the Certificateholders, of the Mortgage Notes and the
      Mortgages.

     

    (c) (1) Assignments
      of Mortgage with respect to each Non-MERS Mortgage Loan other than a Cooperative
      Loan shall be recorded; provided, however, that such Assignments need not be
      recorded if, on or prior to the Closing Date, the Depositor delivers, at its
      own
      expense, an Opinion of Counsel addressed to the Trustee (which must be
      Independent counsel) acceptable to the Trustee, the Rating Agencies and any
      NIMS
      Insurer, to the effect that recording in such states is not required to protect
      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
      such
      Servicer to take such actions as are necessary under applicable law in order
      to
      perfect the interest of the Trustee in the related Mortgaged
      Property.

     

    
      
        
        

      

      
        57

        
          

        

      

      
        
        

      

    

    

     

    (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.

     

    (d) In
      instances where a Title Insurance Policy is required to be delivered to the
      Trustee or the applicable 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 applicable 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 applicable 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 applicable 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.

     

    Section
      2.02. Acceptance
      of Trust Fund by Trustee: Review of Documentation for Trust Fund.

     

    (a) The
      Trustee, by execution and delivery hereof, acknowledges receipt by it or by
      the
      applicable 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 applicable Custodian on behalf of the Trustee, under
      this Section 2.02. The Trustee, or the applicable 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 applicable
      Custodial Agreement as Exhibit B-1, as applicable).

     

    (b) Within
      45
      days after the Closing Date, the Trustee or the applicable 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 applicable 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 applicable 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.

     

    
      
        
        

      

      
        58

        
          

        

      

      
        
        

      

    

    

     

    (c) If
      in the
      course of the review described in paragraph (b) above the Trustee or the
      applicable 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 applicable 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 applicable
      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 applicable 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 applicable 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, any Custodian or the Certificateholders of any unsatisfied
      duty, claim or other liability on any Mortgage Loan or to any
      Mortgagor.

     

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

     

    Section
      2.03. Representations
      and Warranties of the Depositor.

     

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

     

    (i) the
      Depositor is a corporation duly organized, validly existing and in good standing
      under the laws governing its creation and existence and has full corporate
      power
      and authority to own its property, to carry on its business as presently
      conducted, to enter into and perform its obligations under this Agreement,
      and
      to create the trust pursuant hereto;

     

    (ii) the
      execution and delivery by the Depositor of this Agreement have been duly
      authorized by all necessary corporate action on the part of the Depositor;
      neither the execution and delivery of this Agreement, nor the consummation
      of
      the transactions herein contemplated, nor compliance with the provisions hereof,
      will conflict with or result in a breach of, or constitute a default under,
      any
      of the provisions of any law, governmental rule, regulation, judgment, decree
      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
      the
      consummation of the transactions contemplated hereby do not require the consent
      or approval of, the giving of notice to, the registration with, or the taking
      of
      any other action in respect of, any state, federal or other governmental
      authority or agency, except such as has been obtained, given, effected or taken
      prior to the date hereof;

     

    (iv) this
      Agreement has been duly executed and delivered by the Depositor and, assuming
      due authorization, execution and delivery by the Trustee and the Master Servicer
      constitutes a valid and binding obligation of the Depositor enforceable against
      it in accordance with its terms except as 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;

     

    
      
        
        

      

      
        60

        
          

        

      

      
        
        

      

    

    

     

    (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

     

    (vi) immediately
      prior to the transfer and assignment of the Mortgage Loans to the Trustee,
      the
      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. 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 applicable
      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.

    (b) With
      respect to each Qualifying Substitute Mortgage Loan to be delivered to the
      Trustee (or the applicable 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 applicable
      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 the
      Supplemental Interest Trust and all proceeds of any and all property
      constituting the Trust Fund and the Supplemental Interest Trust to secure
      payment of the Certificates (such security interest being, to the extent of
      the
      assets that constitute the Supplemental Interest Trust, pari passu with the
      security interest as provided in clause (4) below; (3) this Agreement shall
      constitute a security agreement under applicable law; and (4) the Swap
      Counterparty shall be deemed, during the term of such agreement and while such
      agreement is the property of the Trustee, to have a security interest in all
      of
      the assets that constitute the Supplemental Interest Trust, but only to the
      extent of such Swap Counterparty’s right to payment under the Swap Agreement
      (such security interest being pari passu with the security interest as provided
      in clause (2) above). 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.

     

    (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 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 Offered 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 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 P Certificates shall be maintained in
      definitive, fully registered form in a minimum denomination equal to 100% of
      the
      Percentage Interest of such Class of Certificates. 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 may be issued in the form of typewritten
      certificates.

     

    (b) The
      Certificates shall be executed by manual or facsimile signature on behalf of
      the
      Trustee by an authorized officer. Each Certificate 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 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 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 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.

    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

     

    
      
        
        

      

      
        66

        
          

        

      

      
        
        

      

    

    

     

    (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 an ERISA-Restricted Swap Certificate shall be made unless the
      Trustee shall have received a representation letter from the transferee of
      such
      Certificate, substantially in the form set forth in Exhibit H, to the effect
      that either (i) 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 Swap Agreement, the acquisition and holding of the
      ERISA-Restricted Swap Certificate are eligible for exemptive relief under
      Prohibited Transaction Class Exemption (“PTCE”) 84-14, PTCE 90-1, PTCE 91-38,
      PTCE 95-60 or PTCE 96-23. 

     

    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 (solely in the case of the
      Class X Certificate, after the termination of the Swap Agreement), 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.

     

    
      
        
        

      

      
        67

        
          

        

      

      
        
        

      

    

    

    
      Except
        in
        the case of Definitive Certificates, the representations set forth in the
        two
        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 an ERISA
        Restricted Swap 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 ERISA Restricted Swap 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 ERISA Restricted Swap
        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 an ERISA
      Restricted Swap Certificate, 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 ERISA Restricted
      Swap 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 ERISA
      Restricted Swap 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 ERISA Restricted Swap 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”).

     

    
      
        
        

      

      
        68

        
          

        

      

      
        
        

      

    

    

     

    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, the 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 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 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).

     

    (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.

     

    
      
        
        

      

      
        70

        
          

        

      

      
        
        

      

    

    

     

    (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.

     

    The
      Trustee may appoint a Paying Agent (which may be the Trustee), acceptable to
      the
      NIMS Insurer, for the purpose of making distributions to Certificateholders
      hereunder. The Trustee shall cause such Paying Agent 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. 

     

    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 6.21,
      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 (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.

     

    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):

     

    
      
        
        

      

      
        71

        
          

        

      

      
        
        

      

    

    

     

    (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.

      Account.

     

    (a) On
      the
      Closing Date, the Master Servicer shall open and shall thereafter maintain
      a
      segregated account held in trust (the “Collection Account”), entitled
“Collection Account, Aurora Loan Services LLC, as Master Servicer, in trust
      for
      the benefit of the Holders of Lehman XS Trust Mortgage Pass-Through
      Certificates, Series 2006-4N” or its nominee. 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
      new Collection Account that is an Eligible Account within 15 days and transfer
      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,

    (ii) all
      payments on account of interest on the Mortgage Loans, in all cases, net of
      the
      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

      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

      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 and the Holders of Lehman XS Trust Mortgage
      Pass-Through Certificates, Series 2006-4N. 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.

     

    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 applicable 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 applicable 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;

     

    
      
        
        

      

      
        75

        
          

        

      

      
        
        

      

    

    

     

    (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 applicable
      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).

     

    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).

     

    
      
        
        

      

      
        76

        
          

        

      

      
        
        

      

    

    

     

    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 and shall be accounted for in such
      manner.

     

    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 are 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.

    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.
      In preparing or furnishing the foregoing information, the Trustee shall be
      entitled to rely conclusively on the accuracy 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 Swap Agreement, that has been provided to the Trustee
      by
      the Swap Counterparty, 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 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 Trustee 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

    Section
      4.04. Certificate
      Account.

     

    (a) The
      Trustee shall establish and maintain in its name, as trustee, a trust account
      (the “Certificate Account”) entitled “Certificate Account, U.S. Bank National
      Association, as Trustee, in trust for the benefit of the Holders of Lehman
      XS
      Trust Mortgage Pass-Through Certificates, Series 2006-4N” until disbursed
      pursuant to the terms of this Agreement. The Certificate Account shall be an
      Eligible Account and shall be for the benefit of the Certificateholders. If
      the
      existing Certificate Account ceases to be an Eligible Account, the Trustee
      shall
      establish a new Certificate Account that is an Eligible Account within 20
      Business Days and transfer all funds and investment property on deposit in
      such
      existing Certificate Account into such new Certificate Account. The Certificate
      Account shall relate solely to the Certificates issued hereunder and funds
      in
      the Certificate Account shall be held separate and apart from and shall not
      be
      commingled with any other monies including, without limitation, other monies
      of
      the Trustee held under this Agreement. The Trustee shall give to the Depositor,
      Master Servicer and any NIMS Insurer prior written notice of the name and
      address of the depository institution at which the Certificate Account is
      maintained and the account number of such Certificate Account. 

     

    (b) The
      Trustee shall deposit or cause to be deposited into the Certificate Account,
      on
      the day on which, or, if such day is not a Business Day, the Business Day
      immediately following the day on which, any monies are remitted by the Master
      Servicer to the Trustee, all such amounts. The Trustee shall make withdrawals
      from the Certificate Account only for the following purposes:

     

    (i) to
      pay
      itself any investment income earned with respect to funds in the Certificate
      Account invested in Eligible Investments as set forth in subsection (c) below,
      and to make payments to itself and others prior to making distributions pursuant
      to Section 5.02 for any expenses or other indemnification owing to itself and
      others pursuant to any provision of this Agreement or any Custodial Agreement;
      provided that such payments are for “unanticipated expenses” within the meaning
      of Treasury Regulation Section 1.860G-1(b)(3)(ii);

     

    
      
        
        

      

      
        81

        
          

        

      

      
        
        

      

    

    

     

    (ii) to
      make
      payment to itself pursuant to any provision of this Agreement, or to reimburse
      itself or its agents for any amounts reimbursable to it pursuant to Sections
      6.11, 6.12 or 7.01; provided that such payments are for “unanticipated expenses”
within the meaning of Treasury Regulation Section
      1.860G-1(b)(3)(ii);

     

    (iii) to
      withdraw amounts deposited in the Certificate Account in error;

     

    (iv) to
      make
      payments to itself and others pursuant to any provision of this Agreement;
      and

     

    (v) to
      clear
      and terminate the Certificate Account pursuant to Section 7.02.

     

    Any
      withdrawals described in the preceding sentence shall be allocated and limited
      to collections or other recoveries and shall be accounted for in such
      manner.

     

    The
      Trustee may invest, or cause to be invested, funds held in the Certificate
      Account, which funds, if invested, shall be invested in Eligible Investments
      (which may be obligations of 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 Trustee (in its capacity as such) or its nominee.
      All
      income and gain realized from any such investment shall be compensation to
      the
      Trustee and shall be subject to its withdrawal on order from time to time.
      The
      amount of any losses incurred in respect of any such investments shall be paid
      by the Trustee for deposit in the Certificate Account out of its own funds,
      without any right of reimbursement therefor, immediately as
      realized.

     

    Except
      as
      otherwise expressly provided in this Agreement, if any default occurs in the
      making of a payment due under any Eligible Investment, or if a default occurs
      in
      any other performance required under any Eligible Investment, the Trustee may
      and, subject to Section 6.01 and Section 6.02(iv), upon the request of the
      NIMS
      Insurer, shall take such action as may be appropriate to enforce such payment
      or
      performance, including the institution and prosecution of appropriate
      proceedings.

    DISTRIBUTIONS
      TO HOLDERS OF CERTIFICATES

     

    Section
      5.01. Distributions
      Generally.

     

    
      
        
        

      

      
        82

        
          

        

      

      
        
        

      

    

    

     

    (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 to the Swap Counterparty
      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 and the Swap Counterparty. 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.

     

    Section
      5.02. Distributions
      from the Certificate Account.

     

    (a) On
      each
      Distribution Date, the Trustee (or the Paying Agent on behalf of the Trustee)
      shall withdraw from the Certificate Account the Total Distribution Amount
      (excluding all Prepayment Premiums) and amounts that are available for payment
      to the Swap Counterparty and shall allocate such amount to the interests issued
      in respect of each REMIC and shall distribute such amount as specified in this
      Section. 

     

    (b) On
      each
      Distribution Date, the Trustee shall distribute the Interest Remittance Amount
      as follows:

     

    (i) On
      each
      Distribution Date (or, with respect to clause (1) below, on the related Swap
      Payment Date), the Trustee shall distribute the Interest Remittance Amount
      for
      such date as follows: 

     

    (1) for
      deposit into the Supplemental Interest Trust Account, the Net Swap Payment
      or
      Swap Termination Payment owed to the Swap Counterparty (including amounts
      remaining unpaid from previous Distribution Dates);

     

    
      
        
        

      

      
        83

      Certificates, Current Interest and any Carryforward Interest for such classes
      for such Distribution Date; provided, however, that if funds available are
      insufficient to pay such amounts, any resulting shortfalls will be allocated
      pro
      rata on the basis of Current Interest and Carryforward Interest due such classes
      on such Distribution Date; provided, further, however, any interest shortfall
      resulting from Deferred Interest on the Mortgage Loans will be allocated to
      the
      Senior Certificates and Subordinate Certificates, pro rata, according to the
      Certificate Principal Amount of each such class of Certificates, in reduction
      of
      the amount of interest otherwise distributable to such class of Certificates;
      provided, further, however, that to the extent the amount of Net Negative
      Amortization otherwise allocable to the Senior Certificates and the Subordinate
      Certificates exceeds the amount of Accrued Certificate Interest (as reduced
      by
      each such class’s share of any Net Prepayment Interest Shortfalls for such
      Distribution Date) accrued on the Related REMIC 2 Interest, 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 in respect
      of the Uncertificated Class X Interest, and then, if necessary, among the
      Certificates in proportion to, and up to, the amount of any remaining interest
      otherwise distributable on the Related REMIC 2 Interest;

     

    (3) for
      application pursuant to Section 5.02(b)(ii), any such Interest Remittance Amount
      remaining undistributed for such Distribution Date.

     

    (ii) On
      each
      Distribution Date, the Trustee will distribute the aggregate of any remaining
      Interest Remittance Amounts from Section 5.02(b)(i)(3) above, in the following
      order of priority:

     

    (A) concurrently,
      to each class of Senior Certificates, Current Interest and any Carryforward
      Interest for such classes for such Distribution Date (any shortfall in Current
      Interest and Carryforward Interest to be allocated among such classes in
      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 Section 5.02(b)(i)(2) above;

     

    
      
        
        

      

      
        84

        
          

        

      

      
        
        

      

    

    

     

    (B) to
      each
      class of Subordinate Certificates, in accordance with the Subordinate Priority,
      Current Interest and any Carryforward Interest for such classes for such
      Distribution Date; provided, however, any interest shortfall resulting from
      Deferred Interest on the Mortgage Loans will be allocated to the Senior
      Certificates and the Subordinate Certificates, pro rata, according to the
      Certificate Principal Amount of each such class of Certificates, in reduction
      of
      the amount of interest otherwise distributable to such classes of Certificates;
      provided, further, however, that to the extent the amount of Net Negative
      Amortization otherwise allocable to the Senior Certificates and the Subordinate
      Certificates exceeds the amount of Accrued Certificate Interest (as reduced
      by
      each such class’s share of any Net Prepayment Interest Shortfalls for such
      Distribution Date) accrued on the Related REMIC 2 Interest, 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 in respect
      of the Uncertificated Class X Interest, and then, if necessary, among the
      Certificates in proportion to, and up to, the amount of any remaining interest
      otherwise distributable on the Related REMIC 2 Interest;

     

    (C) to
      the
      Trustee, previously unreimbursed extraordinary costs, liabilities and expenses
      related to the Certificates; and

     

    (D) for
      application as part of Monthly Excess Cashflow for such Distribution Date,
      pursuant to Section 5.02(d), any such Interest Remittance Amount remaining
      undistributed for such Distribution Date.

      all amounts distributed pursuant to this Section 5.02(f)(2) on prior

    Section
      5.04. Advances
      by Master Servicer, 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, any Servicer determines that
      any
      Scheduled Payments due during the related Collection Period (other than Balloon
      Payments) and relating to any of the Mortgage Loans that it services have not
      been received, such Servicer shall advance such amount to the extent provided
      in
      the related Servicing Agreement. If the applicable Servicer fails to remit
      Advances required to be made under the related Servicing Agreement, the Master
      Servicer shall itself make, or shall cause the successor Servicer to make,
      such
      Advance on the Deposit Date immediately following such Determination Date;
      provided, however, that required Advances remitted by the applicable Servicer
      or
      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 or the applicable 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 and the Servicers 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.

     

    
      
        
        

      

      
        92

        
          

        

      

      
        
        

      

    

    

     

    (b) In
      the
      event that the Master Servicer or any 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 or any Servicer that would have
      been
      deposited in such Certificate Account over (b) the amount of any Advance made
      by
      the Master Servicer or such 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 not be responsible for making any Compensating Interest
      Payments not made by the Servicers. Any Compensating Interest Payments made
      by
      the Servicers shall be a component of the Interest Remittance
      Amount.

     

    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.

     

    (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
      5.07. Supplemental
      Interest Trust.

     

    (a) A
      separate trust is hereby established (the “Supplemental Interest Trust”), the
      corpus of which shall be held by the Trustee, in trust, for the benefit of
      the
      holders of the Certificates and the Swap Counterparty. The Trustee, as trustee
      of the Supplemental Interest Trust, shall establish an account (the
“Supplemental Interest Trust Account”), into which LBH shall initially deposit
      $1,000. The Supplemental Interest Trust 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) The
      Trustee shall deposit into the Supplemental Interest Trust Account any Net

      Account any Net Swap Payment required pursuant to Section 5.02(e)(i) or Swap
      Termination Payment required pursuant to Sections 5.02(e)(ii) and
      (viii).

     

    (c) Funds
      in
      the Supplemental Interest Trust Account shall be invested in Eligible
      Investments. Any earnings on such amounts shall be distributed on each

      tax purposes and the Holder thereof shall direct the Trustee, in writing, as
      to
      investment of amounts on deposit therein. The Class X Certificateholders shall
      be liable for any losses incurred on such investments. In the absence of written
      instructions from the Class X Certificateholders as to investment of funds
      on
      deposit in the Supplemental Interest Trust Account, such funds shall be invested
      in the First American Government Obligations Fund or comparable investment
      vehicle. Any amounts on deposit in the Supplemental Interest Trust Account
      in
      excess of the Supplemental Interest Trust Amount on any Distribution Date shall
      be held for distribution pursuant to Section 5.02(e) on the following
      Distribution Date.

     

    (d) Upon
      termination of the Trust Fund, any amounts remaining in the Supplemental
      Interest Trust Account shall be distributed pursuant to the priorities set
      forth
      in Section 5.02(e).

     

    (e) It
      is the
      intention of the parties hereto that, for federal and state income and state
      and
      local franchise tax purposes, the Supplemental Interest Trust be disregarded
      as
      an entity separate from the holder of the Class X Certificates unless and until
      the date when either (a) there is more than one Class X Certificateholder or
      (b)
      any Class of Certificates in addition to the Class X Certificates is
      recharacterized as an equity interest in the Supplemental Interest Trust for
      federal income tax purposes. The Trustee shall not be responsible for any entity
      level tax reporting for the Supplemental Interest Trust.

     

    (f) To
      the
      extent that the Supplemental Interest Trust is determined to be a separate
      legal
      entity from the Trustee, any obligation of the Trustee under the Swap Agreement
      shall be deemed to be an obligation of the Supplemental Interest
      Trust.

    Section
      5.08. Rights
      of Swap Counterparty.
      

     

    The
      Swap
      Counterparty shall be deemed a third-party beneficiary of this Agreement to
      the
      same extent as if it were a party hereto and shall have the right, upon
      designation of an “Early Termination Date” (as defined in the Swap Agreement),
      to enforce its rights under this Agreement, which rights include but are not
      limited to the obligation of the Trustee (A) to deposit any Net Swap Payment
      required pursuant to Sections 5.02(b), 5.02(c) and 5.02(e), and any Swap
      Termination Payment required pursuant to Sections 5.02(b), 5.02(c) and 5.02(e),
      into the Supplemental Interest Trust Account, (B) to deposit any amounts from
      the Basis Risk Reserve Fund required pursuant to Section 5.07(b) into the
      Supplemental Interest Trust Account, (C) to pay any Net Swap Payment required
      pursuant to Section 5.02(e)(i) or Swap Termination Payment required pursuant
      to
      Sections 5.02(e)(ii) and (viii) to the Swap Counterparty and (D) to establish
      and maintain the Supplemental Interest Trust Account, to make such deposits
      thereto, investments therein and distributions therefrom as are required
      pursuant to Section 5.07. For the protection and enforcement of the provisions
      of this Section the Swap Counterparty shall be entitled to such relief as can
      be
      given either at law or in equity.

     

    Section
      5.09. Termination
      Receipts.
      

     

    In
      the
      event of an “Early Termination Event” as defined under the Swap Agreement, (i)
      any Swap Termination Payment made by the Swap Counterparty to the Supplemental
      Interest Trust and paid pursuant to Section 5.02(e)(viii) (“Termination
      Receipts”) will be deposited in a segregated non-interest bearing account which
      shall be an Eligible Account established by the Trustee (the “Termination
      Receipts Account”) and (ii) any amounts received from a replacement Swap
      Counterparty (“Replacement Receipts”) will be deposited in a segregated
      non-interest bearing account which shall be an Eligible Account established
      by
      the Trustee (the “Replacement Receipts Account”). The Trustee shall invest, or
      cause to be invested, funds held in the Termination Receipts Account and the
      Replacement Receipts Account in time deposits of the Trustee as permitted by
      clause (ii) of the definition of Eligible Investments or as otherwise directed
      in writing by a majority of the Certificateholders. All such investments must
      be
      payable on demand or mature on a Swap Payment Date or such other date as
      directed by the Certificateholders. All such Eligible Investments will be made
      in the name of the Trustee of the Supplemental Interest Trust (in its capacity
      as such) or its nominee. All income and gain realized from any such investment
      shall be deposited in the Termination Receipts Account or the Replacement
      Receipts Account, as applicable, and all losses, if any, shall be borne by
      the
      related account. 

     

    Unless
      otherwise permitted by the Rating Agencies as evidenced in a written
      confirmation, the Depositor shall arrange for replacement Swap Agreement(s)
      and
      the Trustee shall promptly, with the assistance and cooperation of the
      Depositor, use amounts on deposit in the Termination Receipts Account, if
      necessary, to enter into replacement Swap Agreement(s) which shall be executed
      and delivered by the Trustee on behalf of the Supplemental Interest Trust upon
      receipt of written confirmation from each Rating Agency that such replacement
      Swap Agreement(s) will not result in the reduction or withdrawal of the rating
      of any outstanding Class of Certificates with respect to which it is a Rating
      Agency.

    Amounts
      on deposit in the Replacement Receipts Account shall be held for the benefit
      of
      the related Swap Counterparty and paid to such Swap Counterparty if the
      Supplemental Interest Trust is required to make a payment to such Swap
      Counterparty following an event of default or termination event with respect
      to
      the Supplemental Interest Trust under the related Swap Agreement. Any amounts
      not so applied shall, following the termination or expiration of such Swap
      Agreement, be paid to the Class X Certificates. Neither the Termination Receipts
      Account nor the Replacement Receipts Account shall be the asset of any REMIC.
      

     

    Section
      5.10. Capitalized
      Interest Account.

     

    (a) No
      later
      than the Closing Date, the Trustee shall establish and maintain a segregated
      trust account that is an Eligible Account, which shall be titled “Capitalized
      Interest Account, U.S. Bank National Association, as trustee for the registered
      holders of Lehman XS Trust Mortgage Pass-Through Certificates Series 2006-4N”
(the “Capitalized Interest Account”). The Trustee shall, promptly upon receipt,
      deposit in the Capitalized Interest Account and retain therein the Capitalized
      Interest Amount remitted on the Closing Date to the Trustee by the Depositor.
      Funds deposited in the Capitalized Interest Account shall be held in trust
      by
      the Trustee on behalf of the Certificateholders for the uses and purposes set
      forth herein. With respect to each Distribution Date up to and including the
      Distribution Date in April 2006, the Trustee will withdraw funds from the
      Capitalized Interest Account and such funds shall be used to pay (i) first,
      to
      the Senior Certificates, the amount of any Basis Risk Shortfalls and Unpaid
      Basis Risk Shortfalls for each such class and such Distribution Date, in
      proportion to the amount of such shortfalls and (ii) second, to the Subordinate
      Certificates, in accordance with the Subordinate Priority, any applicable Basis
      Risk Shortfalls and Unpaid Basis Risk Shortfalls for each such class and such
      Distribution Date. 

     

    (b) The
      Trustee will invest funds deposited in the Capitalized Interest Account in
      Eligible Investments as directed in writing by the Depositor (provided that
      if
      the Trustee does not receive written direction from the Depositor, the amounts
      in the Capitalized Interest Account shall not be invested) with a maturity
      date
      no later than the Business Day preceding each Distribution Date. For federal
      income tax purposes, the Depositor shall be the owner of the Capitalized
      Interest Account and shall report all items of income, deduction, gain or loss
      arising therefrom. At no time will the Capitalized Interest Account be an asset
      of any of the REMICs provided for herein. All income and gain realized from
      investment of funds deposited in the Capitalized Interest Account shall be
      for
      the sole and exclusive benefit of the Depositor and shall be remitted by the
      Trustee to the Depositor on each Distribution Date. The Depositor shall deposit
      in the Capitalized Interest Account the amount of any net loss incurred in
      respect of any such Eligible Investment immediately upon realization of such
      loss.

     

    (c) On
      the
      Distribution Date in April 2006, any amount remaining on deposit in the
      Capitalized Interest Account after withdrawals pursuant to paragraph (a) above
      shall be withdrawn by the Trustee and paid to the Depositor or its
      designee.

    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 NIMS Securities are issued, the Depositor
      shall 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(f)(1) hereof.

     

    (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(f)(1) of
      this
      Agreement. Any amounts that the Trustee is not required to distribute from
      the
      Class X Account pursuant to Section 5.02(f) 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.

      VI

     

    CONCERNING
      THE TRUSTEE EVENTS OF DEFAULT

     

    Section
      6.01. Duties
      of Trustee.

     

    
      
        
        

      

      
        97

        
          

        

      

      
        
        

      

    

    

     

    (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 Swap Counterparty 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;

     

    (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

     

    
      
        
        

      

      
        98

        
          

        

      

      
        
        

      

    

    

     

    (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.

     

    (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 Swap Counterparty 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.

     

    
      
        
        

      

      
        99

        
          

        

      

      
        
        

      

    

    

     

    (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
      Lehman XS Trust Mortgage Pass-Through Certificates, Series 2006-4N 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

      6.02. Certain
      Matters Affecting the Trustee.

     

    Except
      as
      otherwise provided in Section 6.01:

     

    (i) The
      Trustee may request, and may rely 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;

     

    
      
        
        

      

      
        100

        
          

        

      

      
        
        

      

    

    

     

    (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;

     

    (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 Swap Agreement 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
      Swap Agreement 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.

    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, the Master
      Servicer and the Swap Counterparty. 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, the Swap Counterparty 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 the Trustee so removed,
      one
      copy each to the successor trustee and one copy to the Master Servicer, the
      Swap
      Counterparty 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 the Depositor, one copy to the Trustee and one copy to the Master
      Servicer, the Swap Counterparty and any NIMS Insurer; the Depositor shall
      thereupon appoint a successor trustee in accordance with this Section mutually
      acceptable to the Depositor and the Master Servicer and any NIMS
      Insurer.

     

    (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.

     

    
      
        
        

      

      
        103

        
          

        

      

      
        
        

      

    

    

     

    (a) Any
      successor trustee appointed as provided in Section 6.06 shall execute,
      acknowledge and deliver to the Depositor and the Master Servicer and any NIMS
      Insurer and the Swap Counterparty 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 each 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.

     

    
      
        
        

      

      
        104

        
          

        

      

      
        
        

      

    

    

     

    (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 each 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;

     

    (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.

     

    
      
        
        

      

      
        105

        
          

        

      

      
        
        

      

    

    

     

    (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 report 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 in any
      way
      related to any 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 or
      under the Swap Agreement, the Mortgage Loan Sale Agreement, 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:

     

    
      
        
        

      

      
        107

        
          

        

      

      
        
        

      

    

    

     

    (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.

    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

      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

     

    (iv) The
      Master Servicer shall consent to the appointment of a conservator or receiver
      or
      liquidator in any insolvency, readjustment of debt, marshalling of assets and
      liabilities, voluntary liquidation or similar proceedings of or relating to
      the
      Master Servicer or of or relating to all or substantially all of its property;
      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

      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

      permitted hereunder and without the prior written consent of the Trustee, any
      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

      the
      Trustee for the benefit of Certificateholders under the terms of this Agreement,
      including any Advance, on any Deposit Date, which failure continues unremedied

        110

        
          

        

      

      
        
        

      

    

    

     

    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.

     

    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(i), (ii), (iii), (v), (vii) and (ix) to the extent such
      reimbursement relates to the period prior to such Master Servicer’s
      termination.

     

    
      
        
        

      

      
        111

        
          

        

      

      
        
        

      

    

    

     

    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, the
      Swap
      Counterparty 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.

    (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 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 and the
      Swap Counterparty. 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 and the Swap
      Counterparty. 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.

    Section
      6.20. Preparation
      of Tax Returns and Other Reports.

     

    (a) The
      Trustee shall prepare or cause to be prepared on behalf of the Trust Fund,
      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 resulting from any error in
      any
      of such tax or information returns directly resulting from errors in the
      information provided by such Master Servicer.

     

    (b) The
      Trustee shall prepare and file with the Internal Revenue Service (“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.

     

    (c) Reports
      Filed on Form 10-D.

     

    (i) Within
      15
      days after each Distribution Date (or, if applicable, within such shorter period
      of time as is required under the rules of the Commission as in effect from
      time
      to time (the “Rules”)), the Trustee shall prepare and file on behalf of the
      Trust Fund any Form 10-D required by the Exchange Act, in form and substance
      as
      required by the Exchange Act. The Trustee shall file each Form 10-D with a
      copy
      of the related Distribution Date Statement attached thereto. Any disclosure
      in
      addition to the Distribution Date Statement that is required to be included
      on
      Form 10-D (“Additional Form 10-D Disclosure”) shall be determined and prepared
      by and at the direction of the Depositor pursuant to the following paragraph
      and
      the Trustee will have no duty or liability for any failure hereunder to
      determine or prepare any Additional Form 10-D Disclosure, except as set forth
      in
      the next paragraph.

    (ii) As
      set
      forth on Exhibit Q-1 hereto, within five calendar days after the related
      Distribution Date, (A) certain parties to the Lehman XS Trust Mortgage
      Pass-Through Certificates, Series 2006-4N transaction shall be required to
      provide to the Trustee, to the extent known by a responsible officer thereof,
      in
      EDGAR-compatible form (which may be Word or Excel documents easily convertible
      to EDGAR format), or in such other form as otherwise agreed upon by the Trustee
      and such party, the form and substance of any Additional Form 10-D Disclosure,
      if applicable, and included with such Additional Form 10-D Disclosure, an
      Additional Disclosure Notification in the form attached hereto as Exhibit Q-4,
      (B) the Trustee shall forward to the Depositor, the form and substance of the
      Additional Form 10-D Disclosure, and (C) the Depositor will approve, as to
      form
      and substance, or disapprove, as the case may be, the 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 filing 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.

      set
      forth on Exhibit Q-2 hereto, no later than March 15 of each year that the Trust

      performance by the parties listed on Exhibit Q-2 of their duties under this
      paragraph or proactively solicit or procure from such parties any Form 10-K

    (iii) After
      preparing the Form 10-K, the Trustee shall forward electronically a draft copy
      of the Form 10-K to the Exchange Act Signing Party for review and approval.
      If
      the Master Servicer is the Exchange Act Signing Party and the Form 10-K includes
      Additional Form 10-K Disclosure, then the Form 10-K shall also be electronically
      distributed to the Depositor for review and approval. No later than the close

      this Section 6.20. Promptly (but no later than one Business Day) after filing
      with the Commission, the Trustee will make available on its internet website

      strictly observing all applicable deadlines in the performance of their duties
      under this Section 6.20(d), Section 9.25(a), Section 9.25(b) and Section 9.26.
      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-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 10-K,
      not resulting from its own negligence, bad faith or willful
      misconduct.

     

    (iv) Each
      Form

      Certification shall be entitled to indemnification from the Trust Fund for
      any
      liability or expense incurred by it in connection with such certification,
      other

      survive any termination of this Agreement and the resignation or removal of
      such
      Person.

     

    (e) Reports
      Filed on Form 8-K.

     

    (i) Within
      four Business Days after the occurrence of an event requiring disclosure on
      Form
      8-K (each such event, a “Reportable Event”) or such later date as may be
      required by the Commission, and if requested by the Depositor, the Trustee
      shall
      prepare and file on behalf of the Trust Fund any Form 8-K, as required by the
      Exchange Act; provided that the Depositor shall file the initial Form 8-K in
      connection with the issuance of the Certificates. Any disclosure or information
      related to a Reportable Event or that is otherwise required to be included
      on
      Form 8-K (“Form 8-K Disclosure Information”) shall be determined and prepared by
      and at the direction of the Depositor pursuant to the following paragraphs
      and
      the Trustee will have no duty or liability for any failure hereunder to
      determine or prepare any Form 8-K Disclosure Information or any Form 8-K, except
      as set forth in the next paragraph.

     

    (ii) As
      set
      forth on Exhibit Q-3 hereto, for so long as the Trust Fund is subject to the
      Exchange Act reporting requirements, no later than Noon New York City time
      on
      the 2nd Business Day after the occurrence of a Reportable Event (A) certain
      parties to the Lehman XS Trust Mortgage Pass-Through Certificates, Series
      2006-4N transaction shall be required to provide to the Trustee, to the extent
      known by a responsible officer thereof, in EDGAR-compatible form (which may
      be
      Word or Excel documents easily convertible to EDGAR format), or in such other
      form as otherwise agreed upon by the Trustee and such party, the form and
      substance of any Form 8-K Disclosure Information, if applicable, and include
      with such Form 8-K Disclosure Information, an Additional Disclosure Notification
      in the form attached hereto as Exhibit Q-4, (B) the Trustee shall forward to
      the
      Depositor, the form and substance of the Form 8-K Disclosure Information, and
      (C) the Depositor will approve, as to form and substance, or disapprove, as
      the
      case may be, the inclusion of the Form 8-K Disclosure Information. The Trustee
      has no duty under this Agreement to monitor or enforce the performance by the
      parties listed on Exhibit Q-3 of their duties under this paragraph or
      proactively solicit or procure from such parties any Form 8-K Disclosure
      Information. The Sponsor will be responsible for any reasonable fees and
      expenses assessed or incurred by the Trustee in connection with including any
      Form 8-K Disclosure Information on Form 8-K pursuant to this
      paragraph.

     

    (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
      shall sign the Form 8-K and return an electronic or fax copy of such signed
      Form
      8-K (with an original executed hard copy to follow by overnight mail) to the
      Trustee. If a Form 8-K cannot be filed on time or if a previously filed Form
      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 filing with the Commission, the Trustee will, make available on
      its
      internet website a final executed copy of each Form 8-K. The parties to this
      Agreement acknowledge that the performance by the 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, 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 in 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,

      in
      Section 11.07, in each case to the attention of a designated contact specified
      by each of McKee Nelson LLP and the Depositor, respectively.

    PURCHASE
      OF MORTGAGE LOANS AND

    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 and the Swap Counterparty 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 the SWAP REMIC, 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 Purchase Price,
      pursuant to Section 7.03(a) hereof. Upon exercise of such option, the property
      of the Mortgage Pool shall be sold to the Master Servicer at a price (the
“Purchase 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
      Swap Termination Payment payable to the Swap Counterparty 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 Purchase 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”). 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 NIMS 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 Purchase Price to the Master
      Servicer one Business Day prior to the day the Master Servicer is required
      to
      remit the Purchase Price to the Trustee. Following its receipt from the NIMS
      Insurer of the entire Purchase Price and its subsequent remittance to the
      Trustee of the entire Purchase 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. The Master Servicer,
      the
      Servicer, the Trustee and the Custodian shall be reimbursed from the Purchase
      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
      related 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 applicable Custodian, to the extent such amounts
      relate to the Mortgage Loans. 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 Purchase 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 directly resulting from or relating to 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.

      Master Servicer, the Swap Counterparty and the Certificate Registrar at the
      time
      such notice is given to Holders of the related Certificates. The Master Servicer
      shall give notice to the Swap Counterparty on the date the Master Servicer
      elects to exercise its option pursuant to 7.01(b). 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 shall be reimbursed from proceeds received
      from
      the liquidation of the Mortgage Pool.

     

    Section
      7.03. Additional
      Trust Fund Termination Requirements.

     

    (a) 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) On
      the
      date specified for final payment of the Certificates, the Trustee shall make
      final distributions of principal and interest on the Certificates and shall
      pay
      any Swap Termination Payment owed to the Swap Counterparty on the related Swap
      Payment Date (to the extent not paid on previous Swap Payment Dates) in
      accordance with Section 5.02 and, after payment of, or provision for any
      outstanding expenses, distribute or credit, or cause to be distributed or
      credited, to the Holders of the Residual Certificates all cash on hand after
      such final payment (other than cash retained to meet claims), and the Trust
      Fund
      (and each REMIC) shall terminate at that time;

     

    (ii) In
      the
      case of a sale of the assets:

     

    (A) 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

     

    (B) 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, 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.

      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.

     

    (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, any NIMS Insurer, and the Depositor a copy of
      its
      annual unaudited financial statements on or prior to March 15 of each year,
      beginning March 15, 2007. Such financial statements shall include a balance
      sheet, income statement, statement of retained earnings, statement of additional
      paid in capital, statement of changes in financial position and all related
      notes and schedules and shall be in comparative form, certified by a nationally
      recognized firm of Independent Accountants to the effect that such 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 or
      cause the applicable Servicer (if required by the related Servicing Agreement)
      to 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 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.

     

    
      
        
        

      

      
        132

        
          

        

      

      
        
        

      

    

    

     

    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 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
      applicable 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 applicable Custodial Agreement)
      the
      Trustee or the applicable 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 applicable
      Custodian, shall promptly release the related Mortgage File to the Servicer
      and
      neither the Trustee nor such 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 applicable Custodian,
      shall, upon request of the Master Servicer, or of the applicable Servicer,
      and
      delivery to the Trustee or such 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 applicable
      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.

     

    Section
      9.13. Documents,
      Records and Funds in Possession of Master Servicer To Be Held for
      Trustee.

     

    (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 applicable 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 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 respective agents and accountants and to 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 any 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
      Master Servicer is not a party to or bound by any agreement or instrument or
      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;

     

    
      
        
        

      

      
        138

        
          

        

      

      
        
        

      

    

    

     

    (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;

     

    (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 Offering Document 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 resulting from 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 each 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.

    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).

     

    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 applicable 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 applicable 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
      applicable 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.

    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 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 Net Master
      Servicing Fees or 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.

     

    
      
        
        

      

      
        143

        
          

        

      

      
        
        

      

    

    

     

    (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.

     

    (a) Not
      later
      than 30 days after each Distribution Date, the Master Servicer shall, upon
      request, forward to the Trustee and any NIMS Insurer a statement, deemed to
      have
      been certified by a Servicing Officer, setting forth the status of the
      Collection Account maintained by the Master Servicer as of the close of business
      on the related Distribution Date, indicating that all distributions required
      by
      this Agreement to be made by the Master Servicer have been made (or if any
      required distribution has not been made by the Master Servicer, specifying
      the
      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)).

     

    
      
        
        

      

      
        144

        
          

        

      

      
        
        

      

    

    

     

    (b) Not
      later
      than two Business Days following each Distribution Date, the Master Servicer
      shall deliver to one Person designated by the Depositor, in a format consistent
      with other electronic loan level reporting supplied by the Master Servicer
      in
      connection with similar transactions, “loan level” information with respect to
      the Mortgage Loans as of the related Determination Date, to the extent that
      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
      Agreement shall be based upon information supplied to the Master Servicer by
      the
      Servicers without independent verification thereof and the Master Servicer
      shall
      be entitled to rely on such information.

     

    (d) The
      Master Servicer shall provide the Trustee with such information as the Trustee
      may reasonably request in connection with its responsibilities under Section
      10.01 hereof.

     

    Section
      9.25. Assessment
      of Compliance and Attestation Reports.

     

    (a) Assessment
      of Compliance

      15 of each year, commencing in March 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

      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.

     

    (ii) When
      the
      Master Servicer, the Paying Agent (if other than the Trustee) and the Trustee
      (or any Servicing Function Participant engaged by it) submit their assessments
      to the Trustee and the Master Servicer, such parties will also at such time
      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.

     

    
      
        
        

      

      
        145

        
          

        

      

      
        
        

      

    

    

     

    (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 applicable Custodial Agreement in respect of any
      Custodian, and shall notify the Depositor of any exceptions.

     

    (b) Attestation
      Reports

     

    (i) By
      March
      15 of each year, commencing in March 2007, the Master Servicer, the Paying
      Agent
      (if other than the Trustee) and the Trustee, each at its own expense, shall
      cause, and each such party shall cause any Servicing Function Participant
      engaged by it to cause, each at its own expense, a registered public accounting
      firm (which may also render other services to the Master Servicer, the Paying
      Agent and the Trustee, as the case may be) that is a member of the American
      Institute of Certified Public Accountants to furnish a report to the Sponsor,
      the Depositor, the Master Servicer and the Trustee, to the effect that (A)
      it
      has obtained a representation regarding certain matters from the management
      of
      such party, which includes an assertion that such party has complied with the
      Relevant Servicing Criteria, and (B) on the basis of an examination conducted
      by
      such firm in accordance with standards for attestation engagements issued or
      adopted by the PCAOB, it is expressing an opinion as to whether such party’s
      compliance with the Relevant Servicing Criteria was fairly stated in all
      material respects, or it cannot express an overall opinion regarding such
      party’s assessment of compliance with the Relevant Servicing Criteria. In the
      event that an overall opinion cannot be expressed, such registered public
      accounting firm shall state in such report why it was unable to express such
      an
      opinion. Such report must be available for general use and not contain
      restricted use language.

     

    (ii) Promptly
      after receipt of such report from the Master Servicer, the Paying Agent, the
      Trustee or any Servicing Function Participant engaged by such parties, the
      Trustee shall confirm that each assessment submitted pursuant subsection (a)
      of
      this Section 9.25 is coupled with an attestation meeting the requirements of
      this Section and notify the Depositor of any exceptions.

     

    (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.

      Officer’s Certificate stating, as to the signer thereof, that (A) a review of
      such party’s activities during the preceding calendar year or portion thereof
      and of such party’s performance under this Agreement, or such other applicable
      agreement in the case of an Additional Servicer, has been made under such
      officer’s supervision and (B) to the best of such officer’s knowledge, based on
      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
      Servicer shall notify the Depositor, 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
      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. 

     

    (a) 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 and
      an
      assessment report as provided in Section 9.26, which reports the Master Servicer
      shall include in its attestation and assessment reports. 

     

    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 as a result of (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, (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 applicable Servicing Fee
      Rate.

    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, (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 (if applicable)
      and
      shall be accounted for in such manner.

    (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.

     

    
      
        
        

      

      
        151

        
          

        

      

      
        
        

      

    

    

     

    (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 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) The
      Swap
      REMIC 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 Swap Agreement, (iv) the Supplemental Interest Trust and (v) the
      Basis
      Risk Reserve Fund (vi) the Capitalized Interest Account, (vii) the rights to
      receive Prepayment Premiums distributable to the Class P Certificates and (viii)
      the Class X Account. The SWAP REMIC Regular Interests shall be designated as
      the
      regular interests in the SWAP REMIC, and the Class SW-R Interest shall be
      designated as the sole class of residual interest in the SWAP REMIC. Each of
      the
      SWAP REMIC Regular Interests shall have the characteristics set forth in the
      Preliminary Statement.

     

    REMIC
      1
      shall consist of the SWAP REMIC Regular Interests. 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 and other
      than
      the Class LT2-IO Interest) shall be subject to a cap equal to the REMIC
      Pass-Through Rate.

     

    
      
        
        

      

      
        152

        
          

        

      

      
        
        

      

    

    

     

    The
      beneficial ownership of the Class SW-R Interest, the Class LT1-R Interest and
      the Residual Interest shall be represented by the Class R Certificate. None
      of
      the Class SW-R Interest, the Class LT1-R Interest and the Residual Interest
      shall have a principal balance or bear interest.

     

    (n) It
      is
      intended that the rights of each Class of Offered 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 Offered 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 Offered 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 Offered Certificates
      receive payments in respect of Excess Interest, such amounts, to the extent
      not
      derived from payments on the Swap Agreement or 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 Offered 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 beneficial owners of the Offered Certificates shall be treated
      as having entered into a notional principal contract with respect to the
      beneficial owners of the Class X Certificates. Pursuant to each such notional
      principal contract, all beneficial owners of the Offered Certificates shall
      be
      treated as having agreed to pay, on each Distribution Date, to the beneficial
      owners of the Class X Certificates an aggregate amount equal to the excess,
      if
      any, of (i) the amount payable on such Distribution Date on the Related REMIC
      2
      Interest corresponding to such Class of Offered Certificates over (ii) the
      amount payable on such Class of Offered Certificates on such Distribution Date
      (disregarding any amount payable from the Capitalized Interest Account) (such
      excess, a “Class I Shortfall”). A Class I Shortfall shall be allocated to each
      Class of Offered Certificates to the extent that interest accrued on such Class
      for the related Accrual Period at the Certificate Interest Rate for a Class,
      computed by substituting “REMIC Pass-Through Rate” for the Net Funds Cap set
      forth in the definition thereof, exceeds the amount of interest payable on
      such
      Certificate for the related Accrual Period (disregarding any amount payable
      from
      the Capitalized Interest Account), and a Class I Shortfall payable from
      principal collections shall be allocated to the most subordinate Class of
      Offered Certificates with an outstanding principal balance to the extent of
      such
      balance. In addition, pursuant to such notional principal contract, the
      beneficial owner of the Class X Certificates shall be treated as having agreed
      to make payments in respect of Excess Interest to the beneficial holders of
      the
      Offered Certificates in accordance with the terms of this Agreement. Any
      payments to the Certificates in light of the foregoing shall not be payments
      with respect to a “regular interest” in a REMIC within the meaning of Code
      Section 860G(a)(1). However, any payment by beneficial owners of Offered
      Certificates of a Class I Shortfall shall be treated for tax purposes as having
      been received by the beneficial owners of such Certificates in respect of their
      interests in the REMIC 2 and as having been paid by such beneficial owners
      to
      the Class X Certificates pursuant to the notional principal contract. Thus,
      each
      Offered Certificate and each Class X Certificate shall be treated as
      representing not only ownership of regular interests in REMIC 2, but also
      ownership of an interest in (and obligations with respect to) a notional
      principal contract.

     

    
      
        
        

      

      
        153

        
          

        

      

      
        
        

      

    

    

     

    It
      is
      intended that the rights of each Class of Offered Certificates to receive
      payments from the Capitalized Interest Account shall be treated as a right
      in
      interest rate cap contracts written by the Depositor in favor of the holders
      of
      each Class of the Offered 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 Offered 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
      uncertificated Class LT2-IO Interest, the rights to receive payments in respect
      of Class I Shortfalls from the holders of the Offered Certificates, the Swap
      Agreement, the Supplemental Interest Trust, 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 Offered 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 Offered 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).

     

    The
      parties intend that all amounts paid to the Swap Counterparty under the Swap
      Agreement shall be deemed for federal income tax purposes to be paid by the
      Class X Certificates first, out of funds deemed received in respect of the
      Class
      LT2-IO Interest, second, out of funds deemed received in respect of the
      Uncertificated Class X Interest and third, out of funds deemed received in
      respect of Class I Shortfalls described in Section 10.01(n), and the provisions
      hereof shall be interpreted consistently with this intention. 

     

    The
      Supplemental Interest Trust shall be an “outside reserve fund” for federal
      income tax purposes and not an asset of any REMIC. Furthermore, the Holders
      of
      the Class X Certificates shall be the beneficial owners of the Supplemental
      Interest Trust for all federal income tax purposes, and shall be taxable on
      all
      income earned thereon.

     

    (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 any 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.

     

    The
      Swap Loan REMIC:
      On each
      Distribution Date, the Trustee shall first pay or charge as an expense of the
      Swap Loan REMIC all expenses of the Trust Fund for such Distribution Date,
      other
      than any Net Swap Payment or Swap Termination Payment required to be made from
      the Trust Fund.

     

    On
      each
      Distribution Date the Trustee shall distribute the aggregate Interest Remittance
      Amount (net of expenses described in the preceding paragraph) with respect
      to
      each of the SWAP REMIC Regular Interests based on the interest rates for such
      interests set forth in the Preliminary Statement hereto.

     

    On
      each
      Distribution Date, the Trustee shall distribute the aggregate Principal
      Remittance Amount with respect to the SWAP REMIC Regular Interests, first to
      the
      Class SW-Z Interest until its principal balance is reduced to zero, and then
      sequentially, to the other SWAP REMIC Regular Interests in ascending order
      of
      their numerical class designation, and, with respect to each pair of classes
      having the same numerical designation, in equal amounts to each such class,
      until the principal balance of each such class is reduced to zero. All losses
      on
      the Mortgage Loans shall be allocated among the SWAP REMIC Regular Interests
      in
      the same manner that principal distributions are allocated. Increases in
      principal amount as a result of Subsequent Recoveries with respect to the
      Mortgage Loans shall be allocated among the SWAP REMIC Regular Interests in
      the
      reverse fashion from the manner in which losses are allocated. Increases in
      principal amount as a result of Net Negative Amortization with respect to the
      Mortgage Loans for any Distribution Date shall be allocated among the SWAP
      REMIC
      Regular Interests, first to the Class SW-Z Interest up to an amount equal to
      the
      accrued interest thereon for such Distribution Date, and then sequentially,
      to
      the other SWAP REMIC Regular Interests in ascending order of their numerical
      class designation, and, with respect to each pair of classes having the same
      numerical designation, in equal amounts to each such class, up to an amount
      equal to the accrued interest thereon for such Distribution Date. Any amounts
      remaining in the SWAP REMIC after the aforementioned distributions shall be
      distributed to the Class SW-R Interest.

    REMIC
      1:
      All
      payments received by REMIC 1 with respect to the SWAP REMIC Regular Interests
      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. 

     

    On
      each
      Distribution Date,

     

    (i) interest
      shortfalls with respect to the Mortgage Loans (other than interest shortfalls
      attributable to Negative Amortization) shall be allocated to the REMIC 1 Regular
      Interests (other than the Class LT1-IO Interest) pro rata based on the principal
      amounts of such interests immediately prior to such Distribution
      Date;

     

    (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) cash
      received by REMIC 1 with respect to the SWAP REMIC Regular Interests shall
      be
      distributed first to the Class LT1-IO Interest in reduction of its principal
      balance so that its principal balance is as close as possible to zero. Any
      remaining cash shall be distributed to, and losses with respect to the Mortgage
      Loans shall be allocated to:

     

    first,
      to the

      principal balance is as close as possible to 50% of the principal balance of

    If
      on
any
      Distribution Date there is an increase in the Certificate Principal Amount
      of
      any Offered Certificate as a result of the proviso in the definition of

      in
      the principal amount of the REMIC 1 Regular Interests allocated as
      follows:

     

    first,
      to each
      of the REMIC 1 Regular Interests (other than the Class LT1-X Interest and other
      than the Class LT1-IO Interest) so that the principal balance of each such

      as possible to the sum of (x) 50% of the aggregate Scheduled Principal Balance
      of the Mortgage Loans and (y) 50% of the Overcollateralization
      Amount.

     

    (s) Notwithstanding
      the priority and sources of payments set forth in Article 5 hereof or otherwise,
      the Trustee shall account for all distributions with respect to a Class of
      Certificates in amounts that differ from those payable pursuant to the regular
      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).

    Section
      10.02.  Prohibited
      Transactions and Activities.

     

    None
      of
      the Depositor, the Master Servicer or the Trustee shall sell, dispose of, or
      substitute for any of the Mortgage Loans, except in a disposition pursuant
      to
      (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund,
      (iii) the termination of the REMIC holding such Mortgage Loan pursuant to
      Article VII of this Agreement, (iv) a substitution pursuant to Article II of
      this Agreement or (v) a repurchase of Mortgage Loans pursuant to Article II
      of
      this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of
      any
      investments in the Certificate Account for gain, nor accept any contributions
      to
      any REMIC after the Closing Date, unless it has received an Opinion of Counsel
      (at the expense of the party causing such sale, disposition, or substitution),
      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
      Trust Fund (except pursuant to the provisions of this Agreement).

     

    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.

     

    
      
        
        

      

      
        159

        
          

        

      

      
        
        

      

    

    

    
      (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.

      (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 but without the consent
        of
        the Swap Counterparty (except to the extent that the rights or obligations
        of
        (1) the Swap Counterparty hereunder or (2) the Swap Counterparty under the
        Swap
        Agreement (or the ability of the Trustee on behalf of the Supplemental Interest
        Trust to perform fully and timely its obligations under the Swap Agreement),
        are
        affected thereby, in which case prior written consent of the Swap Counterparty
        is required) 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, the NIMS Insurer and the Swap Counterparty shall
        be
        provided with an Opinion of Counsel addressed to the Trustee, the NIMS Insurer
        and the Swap Counterparty (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, but without the consent of the
      Swap
      Counterparty (except to the extent that the rights or obligations of (1) the
      Swap Counterparty hereunder or (2) the Swap Counterparty under the Swap
      Agreement (or the ability of the Trustee on behalf of the Supplemental Interest
      Trust to perform fully and timely its obligations under the Swap Agreement),
      are
      affected thereby, in which case prior written consent of the Swap Counterparty
      is required) 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 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, the Swap Counterparty 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
      such consent shall approve the substance thereof. The manner of obtaining such
      consents and of evidencing the authorization of the execution thereof by Holders
      shall be subject to such reasonable regulations as the Trustee may
      prescribe.

     

    (e) Notwithstanding
      anything to the contrary in any Servicing Agreement, the Trustee shall not
      consent to any amendment of any Servicing Agreement unless (i) such amendment
      is
      effected pursuant to the standards provided in this Section with respect to
      amendment of this Agreement and (ii) except for a Permitted Servicing Amendment,
      any such amendment pursuant to Section 11.03(a)(iii) shall not be materially
      inconsistent with the provisions of such Servicing Agreement.

     

    (f) Notwithstanding
      anything to the contrary in this Section 11.03, this Agreement may be amended
      from time to time by the Depositor, the Master Servicer and the Trustee to
      the
      extent necessary, in the judgment of the Depositor and its counsel, to comply
      with the Rules, Regulation AB and any related rules and
      regulations.

     

    Section
      11.04.  Voting
      Rights.

     

    Except
      to
      the extent that the consent of all affected Certificateholders is required
      pursuant to this Agreement, with respect to any provision of this Agreement
      requiring the consent of Certificateholders representing specified percentages
      of aggregate outstanding Certificate Principal Amount or Class Notional Amount
      (or Percentage Interest), Certificates owned by the Depositor, the Master
      Servicer, the Trustee, the Servicer or Affiliates thereof are not to be counted
      so long as such Certificates are owned by the Depositor, the Master Servicer,
      the Trustee, any Servicer or any Affiliate thereof.

    (a) For
      so
      long as any of the Certificates of any Series or Class are “restricted
      securities” within the meaning of Rule 144(a)(3) under the Act, each of the
      Depositor, the Master Servicer and the Trustee agree to cooperate with each
      other to provide to any Certificateholders, and to any prospective purchaser
      of
      Certificates designated by such holder, upon the request of such holder or
      prospective purchaser, any information required to be provided to such holder
      or
      prospective purchaser to satisfy the condition set forth in Rule 144A(d)(4)
      under the Act. Any reasonable, out-of-pocket expenses incurred by the Trustee
      in
      providing such information shall be reimbursed by the Depositor.

     

    (b) The
      Trustee shall make available to any person to whom a Prospectus was delivered,
      upon the request of such person specifying the document or documents requested,
      (i) a copy (excluding exhibits) of any report on Form 8-K, Form 10-D or Form
      10-K filed with the Commission pursuant to Section 6.20(c), (d) or (e) and
      (ii)
      a copy of any other document incorporated by reference in the Prospectus (to
      the
      extent that the Trustee has such documents in its possession or such documents
      are reasonably obtainable by the Trustee). Any reasonable out-of-pocket expenses
      incurred by the Trustee in providing copies of such documents shall be
      reimbursed by the Depositor.

    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 the NIMS Insurer, such consent not to be unreasonably
      withheld;

     

    
      
        
        

      

      
        165

        
          

        

      

      
        
        

      

    

    

     

    (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 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;

     

    (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

                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.

              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

                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.

              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.

                of the
                Code and the regulations promulgated thereunder and that such transfer
                of
                a Residual Certificate will not be disregarded for federal income
                tax

                States trustees have authority to control all substantial decisions
                of the

      _____________________________ (the “Transferee”), and has no actual knowledge
      that such affidavit is not true and has no reason to believe that the
      information contained in paragraph 7 thereof is not true, and has no reason
      to
      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
      with
      respect to a Residual Certificate. In addition, the Transferor has conducted
      a
      reasonable investigation at the time of the transfer and found that the
      Transferee had historically paid its debts as they came due and found no
      significant evidence to indicate that the Transferee will not continue to pay
      its debts as they become due.

                from
                such transferee in the form hereof to confirm that the proposed sale
                is
                being made pursuant to an exemption from, or in a transaction not

      accordance with Item 1123 of Regulation AB (the “Compliance Statement”),] the
      report on assessment of the Company’s compliance with the Servicing Criteria set
      forth in Item 1122(d) of Regulation AB (the “Servicing Criteria”), provided in

    (2) Based
      on
      my knowledge, the Company Servicing Information, taken as a whole, does not
      contain any untrue statement of a material fact or omit to state a material
      fact

      which such statements were made, not misleading with respect to the period
      of
      time covered by the Company Servicing Information;

     

    (3) Based

      my knowledge, all of the Company Servicing Information required to be provided
      by the Company under the Agreement has been provided to the Depositor, the

    (4) I
      am
      responsible for reviewing the activities performed by [_______] as [_______]
      under the [_______] (the “Agreement”), and based on my knowledge [and the
      compliance review conducted in preparing the Compliance Statement] and except
      as
      disclosed in [the Compliance Statement,] the Servicing Assessment or the
      Attestation Report, the Company has fulfilled its obligations under the
      Agreement in all material respects; and

     

    (5) [The
      Compliance Statement required to be delivered by the Company pursuant to the
      Agreement, and] [The] [the] Servicing Assessment and Attestation Report required
      to be provided by the Company and [by any Subservicer or Subcontractor] pursuant
      to the Agreement, have been provided to the Depositor, the Master Servicer
      and
      the Trustee. Any material instances of noncompliance described in such reports
      have been disclosed to the Depositor, the Master Servicer and the Trustee.

      material instance of noncompliance with the Servicing Criteria has been
      disclosed in such reports.

    This
      TRUST AGREEMENT, dated as of March 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”), WELLS FARGO BANK, N.A., a national banking corporation, as
      securities administrator (the “Securities Administrator”) 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 (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 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 Depositor,
      the Master Servicer, the Securities Administrator 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. The
      Depositor, the Securities Administrator 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 the
      rights to Prepayment Penalty Amounts or the Funding Account) be treated for
      federal income tax purposes as comprising seven real estate mortgage investment
      conduits (each a “REMIC” or, in the alternative, REMIC I-1, REMIC I-2, REMIC
      I-3, REMIC II-1 and REMIC II-2). As
      is
      described in Section 10.01 hereof, the Trust Fund will also be treated for
      federal income tax purposes as including six grantor trusts.

              The

                interest
                in REMIC I-1. The Class LTI1-R Interest will not have a principal
                amount
                or an interest rate. The Class LTI1-R Interest shall be represented
                by the
                Class R Certificate.

            

    

     

    Distributions
      shall be deemed to be made to the REMIC I-1 Regular Interests first, so as
      to
      keep the uncertificated principal balance of each REMIC I-1 Regular Interest
      ending with the designation “B” equal to 1% of the aggregate Scheduled Principal
      Balance of the Mortgage Loans in the related Mortgage Pool; second, to each
      REMIC I-1 Regular Interest ending with the designation “A” so that the
      uncertificated principal balance of each such REMIC I-1 Regular Interest is
      equal to 1% of the excess of (x) the aggregate Scheduled Principal Balance
      of
      the Mortgage Loans in the related Mortgage Pool over (y) the aggregate Class
      Principal Amounts of the Certificate Group related to such Mortgage Pool (except
      that if 1% of any such excess is greater than the principal amount of the
      corresponding REMIC I-1 Regular Interest ending with the designation “A”, the
      least amount of principal shall be distributed to such REMIC I-1 Regular
      Interests such that the REMIC I-1 Subordinated Balance Ratio is maintained);
      and
      finally, any remaining principal to the Class LTI1-Z Interest. Realized Losses
      shall be applied after all distributions have been made on each Distribution
      Date first, so as to keep the uncertificated principal balance of each REMIC
      I-1
      Regular Interest ending with the designation “B” equal to 1% of the aggregate
      Scheduled Principal Balance of the Mortgage Loans in the related Mortgage Pool;
      second, to each REMIC I-1 Regular Interest ending with the designation “A” so
      that the uncertificated principal balance of each such REMIC I-1 Regular
      Interest is equal to 1% of the excess of (x) the aggregate Scheduled Principal
      Balance of the Mortgage Loans in the related Mortgage Pool over (y) the
      aggregate Class Principal Amounts of the Certificate Group related to such
      Mortgage Pool (except that if 1% of any such excess is greater than the
      principal amount of the corresponding REMIC I-1 Regular Interest ending with
      the
      designation “A”, the least amount of Realized Losses shall be allocated to such
      REMIC I-1 Regular Interests such that the REMIC I-1 Subordinated Balance Ratio
      is maintained); and third, the remaining Realized Losses shall be allocated
      to
      the Class LTI1-Z Interest. All computations with respect to any REMIC I-1
      Interest shall be taken out to eight decimal places.

    If
      on any
      Distribution Date there is an increase in the Certificate Principal Amount
      of
      any Class of Group I Certificates as a result of the proviso in the definition
      of Certificate Principal Amount, then, prior to distributions of principal
      and
      allocations of losses on such Distribution Date with respect to REMIC I-1,
      there
      shall be a corresponding increase in the principal amount of the REMIC I-1
      Regular Interests, with such increase allocated among the REMIC I-1 Regular
      Interests as follows: (i) first, to each REMIC I-1 Regular Interest ending
      with
      the designation “B” so as to keep the uncertificated principal balance of such
      REMIC I-1 Regular Interest equal to 1% of the aggregate Scheduled Principal
      Balance of the Mortgage Loans in the related Mortgage Pool, (ii) second, to
      each
      REMIC I-1 Regular Interest ending with the designation “A”, so that the
      uncertificated principal balance of each such REMIC I-1 Regular Interest is
      as
      close as possible to (but does not exceed) 1% of the excess of (x) the aggregate
      Scheduled Principal balance of the Mortgage Loans in the related Mortgage Pool
      over (y) the aggregate Class Principal Amounts of the Senior Certificates of
      the
      Certificate Group related to such Mortgage Pool; provided, however, that (a)
      the
      REMIC I-1 Subordinated Balance Ratio is maintained and (b) amounts allocated
      to
      any REMIC I-1 Regular Interest pursuant to this clause (ii) shall not exceed
      the
      amount of any previous realized losses allocated to such REMIC I-1 Regular
      Interest not previously offset by distributions or increases in the principal
      amount of such REMIC I-1 Regular Interest and (iii) finally, all remaining
      increases are allocated to the Class LTI1-Z Interest.

      payment shall be treated as made to the Class LTI2-B7I Interest in reduction
      of
      the principal balance thereof, if any, to zero.

     

    If
      on any
      Distribution Date there is an increase in the Certificate Principal Amount
      of
      any Class of Group I Certificates as a result of the proviso in the definition

      Interest for each Distribution Date through the Distribution Date in February
      2013. Such “specified portion” shall equal all interest accruing on the Class

              The
                Class LTII1-R Interest shall represent the sole class of residual
                interest
                in REMIC II-1. The Class LTII1-R Interest will not have a principal
                amount
                or an interest rate. The Class LTII1-R Interest shall be represented
                by
                the Class R Certificate.

            

    

     

    Principal
      and interest shall be payable to, and shortfalls, losses and prepayments are
      allocable to, the REMIC II-1 Regular Interests as such amounts are payable
      and
      allocable to the Corresponding Certificates or REMIC II-2 Interests.
      Notwithstanding the preceding sentence, (i) the first $0.22 of losses with
      respect to principal on the Mortgage Loans in Mortgage Group II shall be
      allocated to the Class LTII1-B7II Interest and (ii) immediately preceding any
      payment to the Class R Certificate pursuant to Section 5.02(e) attributable
      to
      principal received with respect to any Mortgage Loan in Mortgage Group II,
      a
      payment shall be treated as made to the Class LTII1-B7II Interest in reduction
      of the principal balance thereof, if any, to zero.

     

    If
      on any
      Distribution Date there is an increase in the Certificate Principal Amount
      of
      any Class of Group II Certificates as a result of the proviso in the definition
      of Certificate Principal Amount, then there shall be a corresponding increase
      in
      the principal amount of the corresponding REMIC II-1 Regular
      Interest.

     

    REMIC
      II-2

    

    REMIC
      II-2 shall hold as its assets the several classes of uncertificated REMIC II-1
      Regular Interests.

    

    Each
      of
      the Group II Certificates is referred to herein as a REMIC II-2 Regular Interest
      and is hereby designated as a regular interest in REMIC II-2. The Class LTII2-R
      Interest is hereby designated as the sole class of residual interest in REMIC
      II-2. The Class LTII2-R Interest shall be represented by the Class R
      Certificate. The Class LTII2-R Interest shall not have a principal amount or
      an
      interest rate.

    The
      REMIC
      II-2 Regular Interests and the Class LTII2-R Interest are referred to herein
      as
      the REMIC II-2 Interests.

     

    Solely
      for the purposes of the REMIC Provisions, the Class 4-AX Certificates shall
      represent a “specified portion” of the interest accrued on the Class LTII1-4A
      Interest for each Distribution Date through the Distribution Date in February
      2016. Such “specified portion” shall equal all interest accruing on the Class
      LTII1-4A Interest in excess of the interest accruing thereon at a per annum
      rate
      equal to 6.00%.

      In the

      Loan
      that, on the date of substitution, (i) has a Scheduled Principal Balance
      (together with that of any other mortgage loan substituted for the same Deleted
      Mortgage Loan) as of the Due Date in the month in which such substitution occurs
      not in excess of the Scheduled Principal Balance of the related Deleted Mortgage
      Loan, provided, however, that, to the extent that the Scheduled Principal
      Balance of such Mortgage Loan is less than the Scheduled Principal Balance
      of
      the related Deleted Mortgage Loan, then such differential in principal amount,
      together with interest thereon at the applicable Mortgage Rate net of the
      applicable Master Servicing Fee and the applicable Servicing Fee from the date
      as to which interest was last paid through the end of the Due Period in which
      such substitution occurs, shall be paid by the party effecting such substitution
      to the Master Servicer for deposit into the Collection Account, and shall be
      treated as a Principal Prepayment hereunder; (ii) has a Net Mortgage Rate not
      lower than the Net Mortgage Rate of the related Deleted Mortgage Loan and will
      be a Discount Mortgage Loan if the Deleted Mortgage Loan was a Discount Mortgage
      Loan or a Non-Discount Mortgage Loan if the Deleted Mortgage Loan was a
      Non-Discount Mortgage Loan; (iii) has a remaining stated term to maturity not
      more than eighteen months longer than, and not more than eighteen months shorter
      than, the remaining term to stated maturity of the related Deleted Mortgage
      Loan; (iv) (A) has a Loan-to-Value Ratio as of the date of such substitution
      of
      not greater than 80%, provided, however, that if the related Deleted Mortgage
      Loan has a Loan-to-Value Ratio of greater than 80%, then the Loan-to-Value
      Ratio
      of such substitute Mortgage Loan may be greater than 80% but shall not be
      greater than the Loan-to-Value Ratio of the related Deleted Mortgage Loan and
      (B) the addition of such substitute Mortgage Loan does not increase the weighted
      average Loan-to-Value Ratio of the related Mortgage Pool by more than 5%; (v)
      will comply with all of the representations and warranties relating to Mortgage
      Loans set forth herein, as of the date as of which such substitution occurs;
      (vi) is not a Cooperative Loan unless the related Deleted Mortgage Loan was
      a
      Cooperative Loan; (vii) if applicable, has the same index as and a margin not
      less than that of the related Deleted Mortgage Loan; (viii) has not been
      delinquent for a period of more than 30 days more than once in the twelve months
      immediately preceding such date of substitution; (ix) is covered by a Primary
      Mortgage Insurance Policy if the related Deleted Mortgage Loan is so covered,
      and the Loan-to-Value Ratio of such Mortgage Loan is greater than 80%; (x)
      has a
      Credit Score not greater than 20 points lower than the Credit Score of the
      related Deleted Mortgage Loan, provided, however, that if the Deleted Mortgage
      Loan does not have a Credit Score, then such substitute Mortgage Loan shall
      have
      a Credit Score equal to or greater than 700; (xi) has its initial adjustment
      date after the related Reset Date; and (xii) has a gross margin no less than
      the
      related Deleted Mortgage Loan. In the event that either one mortgage loan is
      substituted for more than one Deleted Mortgage Loan or more than one mortgage
      loan is substituted for one or more Deleted Mortgage Loans, then (a) the
      Scheduled Principal Balance referred to in clause (i) above shall be determined
      such that the aggregate Scheduled Principal Balance of all such substitute
      Mortgage Loans shall not exceed the aggregate Scheduled Principal Balance of
      all
      Deleted Mortgage Loans and (b) each of (1) the rate referred to in clause (ii)
      above, (2) the remaining term to stated maturity referred to in clause (iii)
      above, (3) the Loan-to-Value Ratio referred to in clause (iv) above and (4)
      the
      Credit Score referred to in clause (x) above shall be determined on a weighted
      average basis, provided that the final scheduled maturity date of any Qualifying
      Substitute Mortgage Loan shall not exceed the Final Scheduled Distribution
      Date
      of any Class of Certificates. Whenever a Qualifying Substitute Mortgage Loan
      is
      substituted for a Deleted Mortgage Loan pursuant to this Agreement, the party
      effecting such substitution shall certify such qualification in writing to
      the
      Trustee and the Master Servicer.

      instrument relating thereto except as specifically set forth

    (i)           with
      respect to each Mortgage Loan, the original Mortgage Note endorsed without

    (ii)          the
      original of any guarantee, security agreement or pledge agreement relating

    (iv)         the
      original of each assumption, modification or substitution agreement, if any,
      relating to the Mortgage Loans, or, as to any assumption, modification or
      substitution agreement which cannot be delivered on or prior to the Closing
      Date

      delivery of the original thereof, together with an Officer’s Certificate of the

      transfer or equivalent instrument (each, an “Intervening Assignment”), as may be
      necessary to show a complete chain of assignment from the originator, or, in
      the
      case of an Intervening Assignment that has been lost, a written Opinion of
      Counsel acceptable to the Trustee that such original Intervening Assignment
      is
      not required to enforce the Trustee’s interest in the Mortgage
      Loans;

     

    (vii)        the
      original Primary Mortgage Insurance Policy or certificate, if private mortgage

      has
      been delivered for recordation, a photocopy of such document, pending delivery

    (x)           with
      respect to any Cooperative Loan, the Cooperative Loan Documents.

     

    The
      parties hereto acknowledge and agree that the form of endorsement attached
      hereto as Exhibit B-4 is intended to effect the transfer to the Trustee, for
      the
      benefit of the Certificateholders, of the Mortgage Notes and the
      Mortgages.

     

    With
      respect to each Participation, the Depositor does hereby deliver to, and deposit
      with, or cause to be delivered to and deposited with, the Trustee, and/or any
      custodian acting on the Trustee’s behalf, a copy of the Participation Agreement
      and the original Participation issued to the Trustee.

     

    (c)           (1)           Assignments
      of Mortgage with respect to each Non-MERS Mortgage Loan other than a Cooperative
      Loan shall be recorded; provided, however, that such Assignments need not be
      recorded if, in the Opinion of Counsel (which must be from Independent counsel)
      acceptable to the Trustee and the Rating Agencies, recording in such states
      is
      not required to protect the Trustee’s interest in the related Non-MERS Mortgage
      Loans. Subject to the preceding sentence, as soon as practicable after the
      Closing Date (but in no event more than 3 months thereafter except to the extent
      delays are caused by the applicable recording office), the Master Servicer
      (or
      its Custodian), 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 a
      Non-MERS Mortgage Loan. With respect to each Cooperative Loan, the Master
      Servicer (or its Custodian), at the expense of the Depositor and with the
      cooperation of the applicable Servicer, shall cause such Servicer to take such
      actions as are necessary under applicable law in order to perfect the interest
      of the Trustee in the related Mortgaged Property.

    (ii)           With
      respect to each MERS Mortgage Loan, the Master Servicer (or its applicable
      Custodian), at the expense of the Depositor and with the cooperation of the
      applicable Servicer, shall cause to be taken such actions by such Servicer
      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.

     

    (d)           In
      instances where a Title Insurance Policy is required to be delivered to the
      Trustee, or to the applicable Custodian on behalf of the Trustee, under clause
      (b)(viii) above and is not so delivered, the Depositor will provide a copy
      of
      such Title Insurance Policy to the Trustee, or to the applicable 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 applicable 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 applicable Collection Account pursuant
      to
      Section 4.01 have been so deposited. All original documents that are not
      delivered to the Trustee or the applicable 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.

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

    (b)           Within
      45 days after the Closing Date, the applicable Custodian will, on behalf of
      the
      Trustee and for the benefit of Holders of the Certificates, 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 and the Master Servicer 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 Mortgage Loan 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 applicable Custodian on behalf of the Trustee, shall make
      sure that the 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 any 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.

     

    (c)           If
      in the course of the review described in paragraph (b) above the Trustee or
      the
      applicable 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 applicable Custodian on behalf
      of the Trustee, shall promptly identify the Mortgage Loan to which such Material
      Defect relates in the Interim Certificate delivered to the Depositor or the
      Master Servicer (and to the Trustee). Within 90 days of its receipt of such
      notice, 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 Depositor
      does
      not so cure such Material Defect, it 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 Servicer 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 applicable 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 applicable Custodian,
      shall deliver to the Trustee, the Depositor and the Master Servicer a Final
      Certification substantially in the form annexed hereto as Exhibit B-3 (or in
      the
      form annexed to the applicable 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 or the Certificateholders of any unsatisfied duty, claim
      or
      other liability on any Mortgage Loan or to any Mortgagor.

     

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

              Representations
                and Warranties of the Depositor.

            

    

     

    (a)           The
      Depositor hereby represents and warrants to the Trustee, for the benefit of
      Certificateholders, the Master Servicer and the Securities Administrator, as
      of
      the Closing Date or such other date as is specified, that:

     

    (i)           the
      Depositor is a corporation duly organized, validly existing and in good standing
      under the laws governing its creation and existence and has full corporate
      power
      and authority to own its property, to carry on its business as presently
      conducted, to enter into and perform its obligations under this Agreement,
      and
      to create the trust pursuant hereto;

     

    (ii)           the
      execution and delivery by the Depositor of this Agreement have been duly
      authorized by all necessary corporate action on the part of the Depositor;
      neither the execution and delivery of this Agreement, nor the consummation
      of
      the transactions herein contemplated, nor compliance with the provisions hereof,
      will conflict with or result in a breach of, or constitute a default under,
      any
      of the provisions of any law, governmental rule, regulation, judgment, decree
      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
      the
      consummation of the transactions contemplated hereby do not require the consent
      or approval of, the giving of notice to, the registration with, or the taking
      of
      any other action in respect of, any state, federal or other governmental
      authority or agency, except such as has been obtained, given, effected or taken
      prior to the date hereof;

     

    (iv)           this
      Agreement has been duly executed and delivered by the Depositor and, assuming
      due authorization, execution and delivery by the Trustee, the Securities
      Administrator and the Master Servicer, constitutes a valid and binding
      obligation of the Depositor enforceable against it in accordance with its terms
      except as 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;

     

    
      
        
        

      

      
        52

        
          

        

      

      
        
        

      

    

    (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

     

    (vi)           immediately
      prior to the transfer and assignment of the Mortgage Loans to the Trustee,
      the
      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 each 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 Lehman
      Brothers Holdings under the Mortgage Loan Sale Agreement, the only right or
      remedy of the Trustee or of any Certificateholder shall be the Trustee’s right
      to enforce the obligations of the applicable Transferor under any applicable
      representation or warranty made by it. The Trustee acknowledges that Lehman
      Brothers Holdings shall have no obligation or liability with respect to any
      breach of a representation or warranty made by it with respect to the Mortgage
      Loans 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 Trustee further acknowledges that 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.

              Discovery
                of Breach.

            

    

     

    It
      is
      understood and agreed that the representations and warranties (i) set forth
      in
      Section 2.03, (ii) of Lehman Brothers Holdings set forth in the Mortgage Loan
      Sale Agreement and assigned to the Trustee by the Depositor hereunder and (iii)
      of each Transferor, assigned by Lehman Brothers Holdings 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 either the Depositor,
      the Master Servicer or the Trustee of a breach of any of such representations
      and warranties that adversely and materially affects the value of the related
      Mortgage Loan, the party discovering such breach shall give prompt written
      notice to the other parties. Within 90 days of the discovery of a breach of
      any
      representation or warranty given or assigned to the Trustee by the Depositor,
      any Transferor, or Lehman Brothers Holdings, the Depositor, such Transferor,
      or
      Lehman Brothers Holdings, 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 (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 any 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 Agreement,
      if any Transferor substitutes for a Mortgage Loan for which there is a breach
      of
      any representations and warranties in the related Transfer Agreement which
      adversely and materially affects the value of such Mortgage Loan and such
      substitute mortgage loan is not a Qualifying Substitute Mortgage Loan, under
      the
      terms of the Mortgage Loan Sale Agreement, Lehman Brothers Holdings will, in
      exchange for such substitute Mortgage Loan, (i) provide the applicable Purchase
      Price for the affected Mortgage Loan or (ii) within two years of the
      Closing Date, substitute such affected Mortgage Loan with a Qualifying
      Substitute Mortgage Loan.

              Repurchase,
                Purchase or Substitution of Mortgage Loans.

            

    

     

    (a)           With
      respect to any Mortgage Loan repurchased by the Depositor pursuant to this
      Agreement, by Lehman Brothers Holdings pursuant to the applicable Mortgage
      Loan
      Sale Agreement or by any 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 shall be deposited in the Collection Account pursuant to Section
      4.01. The Trustee, upon receipt of the full amount of the Purchase Price for
      a
      Deleted Mortgage Loan, or upon receipt of notification from the related
      Custodian that it 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 to the Depositor,
      Lehman Brothers Holdings or the applicable 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 Trustee (or a Custodian), and the Trustee shall have no further
      responsibility with respect to the Mortgage File relating to such Deleted
      Mortgage Loan.

    (b)           With
      respect to each Qualifying Substitute Mortgage Loan to be delivered to the
      Trustee (or a Custodian) pursuant to the terms of this Article II in exchange
      for a Deleted Mortgage Loan: (i) the Depositor, the applicable Transferor,
      or
      Lehman Brothers Holdings, as applicable, must deliver to the Trustee (or its
      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 Qualified 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 at the direction 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 such Servicer if required pursuant to Section 2.01(c)(i), or (ii)
      with respect to a Qualifying Substitute Mortgage Loan that is a MERS Mortgage
      Loan, cause to be taken such actions by such Servicer 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)(ii).

     

    (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 has received an Opinion of Counsel (at
      the
      expense of the party seeking to make the substitution) that, under current
      law,
      such substitution will not (A) affect adversely the status of any REMIC
      established hereunder as a REMIC, or of the related “regular interests” as
“regular interests” in any such REMIC, or (B) cause any such REMIC to engage in
      a “prohibited transaction” or “prohibited contribution” pursuant to the REMIC
      Provisions. The Depositor shall cause the Mortgage Loan Schedule to be amended
      in accordance with the terms of this Agreement.

    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: (i) the rights and obligations
      of the parties shall be established pursuant to the terms of this Agreement;
      (ii) the Depositor hereby grants to the Trustee for the benefit of the Holders
      of the Certificates a first priority security interest 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 (iii) 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.

    (a)           The
      Certificates 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 Principal Amount, as applicable, or in the Percentage
      Interests, specified herein. Each Class of Book-Entry Certificates shall be
      issued in the minimum denominations in Certificate Principal Amount (or Notional
      Amount) or Percentage Interest specified in the Preliminary Statement hereto
      and
      in integral multiples of $1 or 5% (in the case of Certificates issued in
      Percentage Interests) in excess thereof. Each Class of Non-Book Entry
      Certificates other than the Residual Certificate shall be issued in definitive,
      fully registered form 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 Residual Certificate shall
      be
      issued as a single Certificate and maintained in definitive, fully registered
      form in a minimum denomination equal to $100. Each of the Class P Certificates
      shall be maintained in definitive, fully registered form in a minimum
      denomination equal to 25% of the Percentage Interest of such Class of
      Certificates. The Certificates may be issued in the form of typewritten
      certificates. One Certificate of each Class of Certificates other than any
      Class
      of Residual Certificates may be issued in any denomination in excess of the
      minimum denomination.

     

    (b)           The
      Certificates shall be executed by manual or facsimile signature on behalf of
      the
      Authenticating Agent by an authorized officer of the Trustee or the
      Authenticating Agent. Each Certificate shall, on original issue, be
      authenticated by the Authenticating Agent upon the order of the Depositor upon
      receipt by the Trustee of the Mortgage Files described in Section 2.01. No
      Certificate 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 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.

    (c)           The
      Class B5-I, Class B6-I, Class B7-I, Class B5-II, Class B6-II or Class B7-II
      Certificates offered and sold in reliance on the exemption from registration
      under Rule 144A shall be issued initially in the form of one or more permanent
      global Certificates in definitive, fully registered form without interest
      coupons with the applicable legends set forth in Exhibit A added to the forms
      of
      such Certificates (each, a “Restricted Global Security”), which shall be
      deposited on behalf of the subscribers for such Certificates represented thereby
      with the Securities Administrator, as custodian for DTC and registered in the
      name of a nominee of DTC, duly executed and authenticated by the Trustee as
      hereinafter provided. The aggregate principal amounts of the Restricted Global
      Securities may from time to time be increased or decreased by adjustments made
      on the records of the Trustee or DTC or its nominee, as the case may be, as
      hereinafter provided.

     

    The
      Class
      B5-I, Class B6-I, Class B7-I, Class B5-II, Class B6-II or Class B7-II
      Certificates sold in offshore transactions in reliance on Regulation S shall
      be
      issued initially in the form of one or more permanent global Certificates in
      definitive, fully registered form without interest coupons with the applicable
      legends set forth in Exhibit A hereto added to the forms of such Certificates
      (each, a “Regulation S Global Security”), which shall be deposited on behalf of
      the subscribers for such Certificates represented thereby with the Securities
      Administrator, as custodian for DTC and registered in the name of a nominee
      of
      DTC, duly executed and authenticated by the Trustee or the Authenticating Agent
      as hereinafter provided. The aggregate principal amounts of the Regulation
      S
      Global Securities may from time to time be increased or decreased by adjustments
      made on the records of the Securities Administrator or DTC or its nominee,
      as
      the case may be, as hereinafter provided.

     

    (d)           The
      Class B5-I, Class B6-I, Class B7-I, Class B5-II, Class B6-II or Class B7-II
      Certificates sold to an “accredited investor” complying with the transfer
      provision set forth in Section 3.03 under Rule 501(a)(1), (2), (3) or (7) under
      the Act shall be issued initially in the form of one or more Definitive
      Certificates.

              Registration.

            

    

     

    The
      Securities Administrator is hereby appointed, and hereby accepts its appointment
      as, the initial Certificate Registrar in respect of the Certificates and shall
      maintain books for the registration and for the transfer of Certificates (the
      “Certificate Register”). 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.

     

    
      	 	
              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 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.

     

    
      
        
        

      

      
        57

        
          

        

      

      
        
        

      

    

    (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 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 a Regulation S Global Security,
      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. In addition, each Holder of a Regulation S Global Security
      shall be deemed to have represented and warranted to the Trustee, the
      Certificate Registrar and any of their respective successors that: (i) such
      Person is not a U.S. person within the meaning of Regulation S and was, at
      the
      time the buy order was originated, outside the United States and (ii) such
      Person understands that such Certificates have not been registered under the
      Securities Act of 1933, as amended (the “Securities Act”), and that (x) until
      the expiration of the 40-day distribution compliance period (within the meaning
      of Regulation S), no offer, sale, pledge or other transfer of such Certificates
      or any interest therein shall be made in the United States or to or for the
      account or benefit of a U.S. person (each as defined in Regulation S), (y)
      if in
      the future it decides to offer, resell, pledge or otherwise transfer such
      Certificates, such Certificates may be offered, resold, pledged or otherwise
      transferred only (A) to a person which the seller reasonably believes is a
      “qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the
      Securities Act, that is purchasing such Certificates for its own account or
      for
      the account of a qualified institutional buyer to which notice is given that
      the
      transfer is being made in reliance on Rule 144A or (B) in an offshore
      transaction (as defined in Regulation S) in compliance with the provisions
      of
      Regulation S, in each case in compliance with the requirements of this
      Agreement; and it will notify such transferee of the transfer restrictions
      specified in this Section.

    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 the Placement Agent, an
      affiliate (as defined in Rule 405 under the Act) of the Depositor or the
      Placement Agent or (y) being made to a QIB by a transferor that has provided
      the
      Certificate Registrar with a certificate in the form of Exhibit F hereto;
      and

     

    (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 by a transferor who furnishes to the
      Certificate Registrar a letter of the transferee substantially in the form
      of
      Exhibit G hereto.

     

    (d)           No
      Transfer of an ERISA-Restricted Certificate or a Residual 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 Residual
      Certificates or Exhibit H for ERISA-Restricted Certificates to the effect that
      such transferee is not an employee benefit plan or 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 ERISA-Restricted
      Certificates (I) if the Certificate has been the subject of an ERISA-Qualifying
      Underwriting, a representation as set forth in Exhibit H that 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 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
      or
      the Depositor.

     

    Except
      in
      the case of a Definitive Certificate, the representations set forth in the
      immediately preceding paragraph, 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 an
      ERISA-Restricted Certificate or a Residual Certificate (or the acceptance by
      a
      Certificate Owner of the beneficial interest in any Class of ERISA-Restricted
      Certificates or a Residual 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
      ERISA-Restricted Certificates or Residual Certificates or any liability for
      transfers of such Certificates in violation of the transfer
      restrictions.

     

    
      
        
        

      

      
        59

        
          

        

      

      
        
        

      

    

    Notwithstanding
      any other provision herein to the contrary, any purported transfer of an
      ERISA-Restricted Certificate or Residual 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 (or
      its
      custodian), the Certificate Registrar and the Depositor as described above
      shall
      be void and of no effect. The Trustee, the Certificate Registrar and the
      Depositor shall not have any liability to any Person for any registration or
      transfer of any ERISA-Restricted Certificate or Residual 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 Trustee 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 ERISA-Restricted
      Certificate or Residual 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
      ERISA-Restricted 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 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”).

     

    
      
        
        

      

      
        60

        
          

        

      

      
        
        

      

    

    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 or the Certificate Registrar 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 or the Certificate
      Registrar 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 Trustee and the Certificate
      Registrar 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 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. Neither the Trustee
      nor the Certificate Registrar shall 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 the Trustee or the Certificate Registrar
      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, agent or
      nominee thereof, or Non-permitted Foreign Holder. The Trustee or the Certificate
      Registrar shall be entitled 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 or the Certificate Registrar 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 or the Certificate Registrar 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. Neither the Trustee nor the Certificate
      Registrar shall be under any 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).

     

    (g)           Each
      Holder of a Residual Certificate, by such Holder’s acceptance thereof, shall be
      deemed for all purposes to have consented to the provisions of this
      section.

    (h)           Notwithstanding
      any provision to the contrary herein, so long as a Global Security representing
      any of the Class B5-I, Class B6-I, Class B7-I, Class B5-II, Class B6-II or
      Class
      B7-II Certificates remains outstanding and is held by or on behalf of DTC,
      transfers of a Global Security representing any such Certificates, in whole
      or
      in part, shall only be made in accordance with Section 3.01 and this Section
      3.03(h).

     

    (A)           Subject
      to clauses (B) and (C) of this Section 3.03(h), transfers of a Global Security
      representing any of the Class B5-I, Class B6-I, Class B7-I, Class B5-II, Class
      B6-II or Class B7-II or Certificates shall be limited to transfers of such
      Global Security, in whole or in part, to nominees of DTC or to a successor
      of
      DTC or such successor’s nominee.

     

    (B)           Restricted
      Global Security to Regulation S Global Security.
      If a
      holder of a beneficial interest in a Restricted Global Security deposited with
      or on behalf of DTC wishes at any time to exchange its interest in such
      Restricted Global Security for an interest in a Regulation S Global Security,

      Euroclear or Clearstream account to be credited with such increase and (III)
      a
      certificate in the form of Exhibit L-1 hereto given by the holder of such

      has
      been made in compliance with the transfer restrictions applicable to the Global
      Securities, including that the holder is not a U.S. person, and pursuant to
      and
      in accordance with Regulation S, the Certificate Registrar, shall reduce the
      principal amount of the Restricted Global Security and increase the principal
      amount of the Regulation S Global Security by the aggregate principal amount
      of
      the beneficial interest in the Restricted Global Security to be exchanged,
      and
      shall instruct Euroclear or Clearstream, as applicable, concurrently with such
      reduction, to credit or cause to be credited to the account of the Person

    (C)           Regulation
      S Global Security to Restricted Global Security.
      If a
      holder of a beneficial interest in a Regulation S Global Security deposited
      with
      or on behalf of DTC wishes at any time to transfer its interest in such
      Regulation S Global Security to a Person who wishes to take delivery thereof
      in
      the form of an interest in a Restricted Global Security, such holder may,
      subject to the rules and procedures DTC, exchange or cause the exchange of
      such
      interest for an equivalent beneficial interest in a Restricted Global Security.
      Upon receipt by the Certificate Registrar, of (I) instructions from DTC
      directing the Certificate Registrar, to cause to be credited a beneficial
      interest in a Restricted Global Security in an amount equal to the beneficial
      interest in such Regulation S Global Security to be exchanged but not less
      than
      the minimum denomination applicable to such holder’s Certificates held through a
      Restricted Global Security, to be exchanged, such instructions to contain
      information regarding the participant account with DTC to be credited with
      such
      increase, and (II) a certificate in the form of Exhibit L-2 hereto given by
      the
      holder of such beneficial interest and stating, among other things, that the
      Person transferring such interest in such Regulation S Global Security
      reasonably believes that the Person acquiring such interest in a Restricted
      Global Security is a QIB, is obtaining such beneficial interest in a transaction
      meeting the requirements of Rule 144A and in accordance with any applicable
      securities laws of any State of the United States or any other jurisdiction,
      then the Certificate Registrar, will reduce the principal amount of the
      Regulation S Global Security and increase the principal amount of the Restricted
      Global Security by the aggregate principal amount of the beneficial interest
      in
      the Regulation S Global Security to be transferred and the Certificate
      Registrar, shall instruct DTC, concurrently with such reduction, to credit
      or
      cause to be credited to the account of the Person specified in such instructions
      a beneficial interest in the Restricted Global Security equal to the reduction
      in the principal amount of the Regulation S Global Security.

     

    (D)           Other
      Exchanges.
      In the
      event that a Global Security is exchanged for Certificates in definitive
      registered form without interest coupons, pursuant to Section 3.09(c) hereof,
      such Certificates may be exchanged for one another only in accordance with
      such
      procedures as are substantially consistent with the provisions above (including
      certification requirements intended to insure that such transfers comply with
      Rule 144A, comply with Rule 501(a)(1), (2), (3) or (7) or are to Non-U.S.
      Persons in compliance with Regulation S under the Act, as the case may be),
      and
      as may be from time to time adopted by the Certificate Registrar.

     

    (E)           Restrictions
      on U.S. Transfers.

    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 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.

      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 Securities Administrator, the Master Servicer, the
      Trustee, the Certificate Registrar nor any agent of any of them shall be
      affected by notice to the contrary.

                Certificates.

            

    

     

    (a)           Pending
      the preparation of Definitive Certificates, upon the order of the Depositor,
      the
      Trustee shall execute and the Trustee or the Authenticating Agent 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.

     

    (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 Certificate Registrar without charge to the Holder.
      Upon
      surrender for cancellation of any one or more temporary Certificates, the
      Trustee shall execute and the Authenticating Agent shall authenticate and
      deliver in exchange therefore 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.

              Appointment
                of Paying Agent.

            

    

     

    The
      Trustee may appoint a Paying Agent (which may be the Trustee) for the purpose
      of
      making distributions to Certificateholders hereunder. The Securities
      Administrator is hereby appointed, and hereby accepts its appointment as Paying
      Agent in respect of the Certificates. 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. Any Paying Agent shall be either
      a
      bank or trust company or otherwise authorized under law to exercise corporate
      trust powers. To the extent that the Paying Agent is a Person not otherwise
      already subject to the reporting obligations under Regulation AB with respect
      to
      the Trust Fund, such Person shall comply with such obligations in form and
      substance similar to those of the Securities Administrator pursuant to Sections
      6.01, 6.23 and 9.25 and 9.26.

              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, to be delivered to The Depository Trust Company, the initial
      Clearing Agency, by, or on behalf of, the Depositor. 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 Securities Administrator, the Master Servicer, the Paying Agent,
      the Certificate 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;

     

    
      
        
        

      

      
        65

        
          

        

      

      
        
        

      

    

    (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 Certificate Registrar 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, (ii) the
      Depositor, at its option, advises the Trustee in writing that it elects to
      terminate the book-entry system through the Clearing Agency or (iii) 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.

      Eligible Investment is an obligation of the Trustee or the Paying Agent, if
      other than the Trustee, and such Collection Account is maintained with the
      Trustee or the Paying Agent, if other than 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

      Rate Mortgage Loan Trust, Mortgage Pass-Through Certificates, Series 2006-3.
      All
      income and gain realized from any such investment shall be for the benefit
      of
      the Master Servicer, while such Collection Account is maintained by 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 or
      assumption fees 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.

    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 made by it or by such Servicer
      pursuant to Section 5.04 or the applicable Servicing Agreement; the Master
      Servicer’s right to reimburse itself pursuant to this subclause (i) is limited
      to amounts received on or in respect of particular Mortgage Loans (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 applicable Servicing Fee and the Master
      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 for any Advances or Servicing Advances made
      by
      it or by such Servicer 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, it being understood, in the case
      of
      any 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(a)
      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 applicable Servicing Fee and the Master
      Servicing Fee 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;

     

    (iv)         in
      the event it has elected not to pay itself the Master Servicing Fee out of
      any
      Mortgagor payment on account of interest or other recovery with respect to
      a
      particular Mortgage Loan prior to the deposit of such Mortgagor payment or
      recovery in the Collection Account, to pay to itself the Master Servicing Fee
      for each Distribution Date and any unpaid Master Servicing Fees for prior
      Distribution Dates, as reduced pursuant to Section 5.05, from any Mortgagor
      payment as to interest or such other recovery with respect to that Mortgage
      Loan, as is permitted by this Agreement;

     

    (v)          to
      reimburse itself or any Servicer for expenses incurred by and recoverable by
      or
      reimbursable to it or such Servicer pursuant to Section 9.04, 9.06, 9.16 or
      9.22(a) or pursuant to the applicable Servicing Agreement (to the extent such
      reimbursement constitutes “unanticipated expenses” within the meaning of
      Treasury Regulation Section 1.860G-1(b)(3)(ii)), and to reimburse itself for
      any
      expenses reimbursable to it pursuant to Section 10.01(c);

    (vi)         to
      pay to the applicable Person, with respect to each Mortgage Loan or REO Property
      acquired in respect thereof that has been repurchased by such Person pursuant
      to
      this Agreement, all amounts received thereon and not distributed on the date
      on
      which the related repurchase was effected;

     

    (vii)        subject
      to Section 5.04, to pay to itself income earned on the investment of funds
      deposited in the Collection Account;

     

    (viii)       to
      make payments to the Securities Administrator on each Deposit Date for deposit
      into the Certificate Account in the amounts and in the manner provided for
      in
      Section 4.04;

     

    (ix)          to
      make payment to itself, the Trustee and others pursuant to any provision of
      this
      Agreement and to reimburse the 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 any Collection Account pursuant to Section
      7.02;

     

    (xii)         to
      reimburse a successor Master Servicer (solely in its capacity as successor
      Master Servicer, including the Securities Administrator), for any fee or advance
      occasioned by a termination of the Master Servicer, and the assumption of such
      duties by the Securities Administrator or a successor Master Servicer appointed
      by the Securities Administrator 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 Securities Administrator 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 provided such amounts are
      Servicing Fees or “unanticipated expenses” within the meaning of Treasury
      Regulation Section 1.860G-1(b)(3)(ii).

     

    If
      provided in the related Servicing Agreement, each Servicer shall be entitled
      to
      retain as additional servicing compensation any Prepayment Interest Excess
      (to
      the extent not offset by Prepayment Interest Shortfalls). The Servicers of
      the
      Participations shall be entitled to retain as additional servicing compensation
      any Prepayment Penalty Amounts received with respect to the
      Participations.

     

    In
      connection with withdrawals pursuant to subclauses (i), (iii), (iv) and (vi)
      above, the Master Servicer’s or Servicer’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 subclause (i), (iii),
      (iv) and (vi).

    In
      the
      event that the Master Servicer fails on any Deposit Date to remit to the
      Securities Administrator any amounts required to be so remitted to the
      Securities Administrator pursuant to sub-clause (viii) by such date, the
      Master Servicer shall pay the Securities Administrator, for the account of
      the
      Securities Administrator, 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 Securities Administrator 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).

      the
      website are entitled to have a paper copy mailed to them via first class mail

      Securities Administrator by the Master Servicer (in a format agreed to by the
      Securities Administrator and the Master Servicer) no later than four Business
      Days prior to the Distribution Date. In preparing or furnishing the Mortgage
      Loan data to the Securities Administrator, the Master Servicer shall be entitled
      to rely conclusively on the accuracy of the information or data regarding the
      Mortgage Loans and the related REO Property that has been provided to the Master
      Servicer by each Servicer, and the Master Servicer shall not be obligated to
      verify, recompute, reconcile or recalculate any such information or data. The
      Securities Administrator shall be entitled to conclusively rely on the Mortgage
      Loan data provided by the Master Servicer and shall have no liability for any
      errors in such Mortgage Loan data or other information.

     

    On
      each
      Distribution Date, in the event the above referenced Securities Administrator’s
      Internet web site is not accessible to the Depositor, the Securities
      Administrator shall also provide or make available to the Depositor a copy
      of
      the above described written report, to the following address: Lehman Brothers
      Inc., 745 Seventh Avenue, 7th Floor, New York, New York 10019, Attention:
      Michael Hitzmann, or to such other address as the Depositor may
      designate.

     

    (b)           Upon
      the reasonable advance written request of any Certificateholder that is a
      savings and loan, bank or insurance company, which request, if received by
      the
      Trustee or the Securities Administrator, will be promptly forwarded to the
      Master Servicer, the Master Servicer shall provide, or cause to be provided,
      (or, to the extent that such information or documentation is not required to
      be
      provided by a Servicer under the applicable 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 investment in the Certificates; provided,
      however, that the Master Servicer shall be entitled to be reimbursed by such
      Certificateholder for such Master Servicer’s 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 Securities Administrator shall have
      prepared and shall make available, upon written request, to each Person who
      at
      any time during the calendar year was a Certificateholder of record, 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 Certificateholders pursuant to Section 4.03(a) on an annual basis as may
      be
      required to enable such Holders to prepare their federal income tax returns.
      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 Securities Administrator 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 Securities Administrator with such
      Mortgage Loan level information as is necessary for the Securities Administrator
      to prepare such reports.

      administrator, a trust account (the “Certificate Account”), to be held in trust
      for the benefit of the Certificateholders until disbursed pursuant to the terms
      of this Agreement. The Certificate Account shall be an Eligible Account. If
      the
      existing Certificate Account ceases to be an Eligible Account, the Securities
      Administrator shall establish a new Certificate Account that is an Eligible
      Account within 20 Business Days and transfer all funds on deposit in such
      existing Certificate Account into such new Certificate Account. The Certificate
      Account shall relate solely to the Certificates issued hereunder and funds
      in
      the Certificate Account shall be held separate and apart from and shall not
      be
      commingled with any other monies including, without limitation, other monies
      of
      the Securities Administrator held under this Agreement.

     

    (b)           The
      Securities Administrator shall cause to be deposited into the Certificate
      Account on the day on which, or, if such day is not a Business Day, the Business

      withdraw amounts deposited in the Certificate Account in error;

     

    (ii)          to
      pay itself the Securities Administrator Fee and any investment income earned
      with respect to funds in the Certificate Account invested in Eligible
      Investments as set forth in subsection (c) below, and to make payments to

      1.860G-1(b)(3)(ii));

     

    (iii)         to

    (c)           The
      Securities Administrator may invest, or cause to be invested, funds held in
      the
      Certificate Account, which funds, if invested, shall be invested in Eligible
      Investments (which may be obligations of the Securities Administrator). All
      such
      investments must 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 Securities Administrator (in its capacity as
      such) or its nominee. All income and gain realized from any such investment
      shall be paid to the Securities Administrator and shall be subject to its
      withdrawal on order from time to time. The amount of any losses incurred in
      respect of any such investments shall be paid by the Securities Administrator
      for deposit in the Certificate Account out of its own funds, without any right
      of reimbursement therefore, immediately as realized. Funds held in the
      Certificate Account that are not invested shall be held in cash.

                Generally.

            

    

     

    (a)           Subject
      to Section 7.01 with respect to 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 check
      mailed to each Certificateholder’s address as it appears on the Certificate
      Register of the Certificate Registrar or, upon written request made to the
      Securities Administrator at least five Business Days prior to the related
      Distribution Date to any Certificateholder, by wire transfer 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. Wire transfers may be made
      at
      the expense of the Holder requesting such wire transfer by deducting a wire
      transfer fee from the related distribution. 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 Certificate and at such time
      such
      final payment in retirement of the Residual Certificate will be made only upon
      presentation and surrender of such Certificate at the Corporate Trust Office
      of
      the Certificate Registrar. 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 in such Class equally in proportion to their respective initial
      Certificate Principal Amounts (or initial Notional Amounts).

    (b)           Net
      Prepayment Interest Shortfalls for each Mortgage Pool shall be allocated among

    Any
      amount not distributed in respect of any Class on any Distribution Date pursuant
      to the immediately preceding paragraph will be allocated among the remaining
      related Subordinate Classes in proportion to their respective Certificate
      Principal Amounts.

     

    (d)           On
      each Distribution Date, the Paying Agent shall distribute to the Holders of
      the
      Class P-I Certificates, any Prepayment Penalty Amounts paid by borrowers upon
      voluntary full or partial prepayment of the Mortgage Loans in Pool 1, Pool
      2 and
      Pool 3. On each Distribution Date, the Paying Agent shall distribute to the
      Holders of the Class P-II Certificates, any Prepayment Penalty Amounts paid
      by
      borrowers upon voluntary full or partial prepayment of the Mortgage Loans in
      Pool 4.

     

    (e)           On

      the
      Class R Certificate any Available Distribution Amount for each of the Mortgage
      Pools remaining for such Distribution Date after application of all amounts
      described in paragraph (a) through (d) of this Section 5.02. Any distributions
      pursuant to this paragraph (e) shall not reduce the Class Principal Amount
      of
      the Class R Certificate.

     

    (f)           (2)           On
      each Distribution Date prior to the Credit Support Depletion Date but on or
      after the date on which the aggregate Certificate Principal Amount of the Senior
      Certificates of any Certificate Group (other than the Group 4 Certificates)
      has
      been reduced to zero, amounts otherwise distributable as principal on each
      Class
      of Group I Subordinate Certificates in accordance with the priorities set forth
      in Section 5.02(a)(v), in reverse order of priority, in respect of such Class’s
      Subordinate Class Percentage of the Subordinate Principal Distribution Amount
      for the Mortgage Pool relating to such retired Senior Certificates, shall be
      distributed as principal to the Senior Certificates (other than the Group 4
      Certificates) remaining outstanding in accordance with the priorities set forth
      in Sections 5.02(a)(iv), until the Class Principal Amounts thereof have been
      reduced to zero, provided that on such Distribution Date (a) the Aggregate
      Subordinate Percentage for such Distribution Date is less than 200% of the
      Aggregate Subordinate Percentage as of the first Distribution Date or (b) the
      average outstanding principal balance of the Mortgage Loans in Pool 1 (if the
      aggregate Certificate Principal Amount of the Senior Certificates of any other
      Certificate Group other than the Group 4 Certificates have been reduced to
      zero), Pool 2 (if the aggregate Certificate Principal Amount of the Senior
      Certificates of any other Certificate Group other than the Group 4 Certificates
      have been reduced to zero) or Pool 3 (if the aggregate Certificate Principal
      Amount of the Senior Certificates of any other Certificate Group other than
      the
      Group 4 Certificates have been reduced to zero), that are delinquent 60 days
      or
      more for the last six months as a percentage of the related Group Subordinate
      Amount is greater than or equal to 50%. If the Senior Certificates of two or
      more Certificate Groups (other than the Group 4 Certificates) remain
      outstanding, the distributions described above will be made in proportion to
      the
      aggregate Certificate Principal Amount of such Senior Certificates of each
      such
      Certificate Group (other than the Group 4 Certificates).

    (ii)           On
      any Distribution Date on which any Certificate Group (other than the Group
      4
      Certificates) constitutes an Undercollateralized Group, all amounts otherwise
      distributable as principal on the Group I Subordinate Certificates, in reverse
      order of priority (other than amounts necessary to pay unpaid Interest
      Shortfalls) (or, following the Credit Support Depletion Date, such other amounts
      described in the immediately following sentence), will be distributed as
      principal to the Senior Certificates of such Undercollateralized Group in
      accordance with the priorities set forth in Section 5.02(a)(iv), until the
      aggregate Certificate Principal Amount of such Senior Certificates equals the
      Pool Balance of the related Mortgage Pool (such distribution, an
“Undercollateralization Distribution”). In the event that any Certificate Group
      (other than the Group 4 Certificates) constitutes an Undercollateralized Group
      on any Distribution Date following the Credit Support Depletion Date,
      Undercollateralization Distributions will be made from the excess of the
      Available Distribution Amount for the other such Mortgage Pools not related
      to
      an Undercollateralized Group (other than Pool 4) remaining after all required
      amounts have been distributed to the Senior Certificates of the other
      Certificate Groups (other than the Group 4 Certificates). In addition, the
      amount of any unpaid Interest Shortfalls with respect to an Undercollateralized
      Group (other than the Group 4 Certificates) on any Distribution Date (including
      any Interest Shortfalls for such Distribution Date) will be distributed to
      the
      Senior Certificates of such Undercollateralized Group prior to the payment
      of
      any Undercollateralization Distributions from amounts otherwise distributable
      as
      principal on the Group I Subordinate Certificates, in reverse order of priority
      (or, following the Credit Support Depletion Date, as provided in the preceding
      sentence). If more than one of the Certificate Groups (other than the Group
      4
      Certificates) is an Undercollateralized Group, the distributions described
      above
      will be made in proportion to the amount by which the aggregate Certificate
      Principal Amount of the Senior Principal Amount of the Senior Certificates
      of
      each such Certificate Group exceeds the Pool Balance of the related Mortgage
      Pool.

      be allocated in the following order of priority:

     

    first,

      rata,
      in
      accordance with their Class Principal Amounts; provided, that any such loss
      allocated to any Class of Accrual Certificates shall be allocated (subject
      to
      Section 5.03(c)) on the basis of the lesser of (x) the Class Principal Amount
      thereof immediately prior to the applicable Distribution Date and (y) the Class
      Principal Amount thereof on the Closing Date (as reduced by any Realized Losses
      previously allocated thereto); provided, however, that any
      Realized Losses otherwise allocable to the Class 1-A1 Certificates pursuant
      to
      this Section 5.03 shall be allocated to the Class 1-A2 Certificates until the
      Class Principal Amount of such Class has been reduced to zero, any Realized
      Losses otherwise allocable to the Class 2-A1 Certificates pursuant to this
      Section 5.03 shall be allocated to the Class 2-A2 Certificates until the Class
      Principal Amount of such Class has been reduced to zero
      and any
      Realized Losses otherwise allocable to the Class 3-A1 and Class 3-A2
      Certificates pursuant to this Section 5.03 shall be allocated to the Class
      3-A3
      Certificates until the Class Principal Amount of such Class has been reduced
      to
      zero.

     

    Notwithstanding
      the foregoing, the first $0.98 of principal portion of Realized Losses in
      Mortgage Group I shall not be allocated to any Class of
      Certificates.

     

    (ii)           On
      any Distribution Date, the principal portion of each Realized Loss (other than
      any Excess Loss) in respect of a Mortgage Loans in Pools 4 shall be allocated
      in
      the following order of priority:

      reduced to zero;

      to
      any Class of Accrual Certificates (and any Accrual Component) shall be allocated
      (subject to Section

      immediately prior to the applicable Distribution Date and (y) the Class
      Principal Amount thereof on the Closing Date (as reduced by any Realized Losses
      previously allocated thereto).

     

    (c)           Any
      Realized Losses allocated to a Class of Certificates pursuant to Section 5.03(a)
      or (b) shall be allocated among the Certificates of such Class in proportion
      to
      their respective Certificate Principal Amounts or Component Principal Amounts
      of
      such Certificates. Any allocation of Realized Losses pursuant to this paragraph
      (c) shall be accomplished by reducing the Certificate Principal Amount or
      Component Principal Amount of the related Certificates on the related
      Distribution Date in accordance with Section 5.03(d).

      definition of Subordinate Certificate Writedown Amount for such date shall
      effect corresponding reductions (i) in the Class Principal Amount of the lowest
      ranking Class of outstanding Group I Subordinate Certificates and (ii) in the
      Class Principal Amount of the lowest ranking Class of outstanding Group II
      Subordinate Certificates, which reductions shall occur on such Distribution

    (a)           Advances
      shall be made in respect of each Deposit Date as provided herein. If, on any

      received, the Master Servicer shall, or shall cause the applicable Servicer
      to,
      advance such amount on the Deposit Date immediately following such Determination
      Date, less an amount, if any, to be set forth in an Officer’s Certificate to be
      delivered to the Securities Administrator on such Determination Date, which

      advanced the Master Servicer or such 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. The
      Securities Administrator shall be able to rely conclusively on any
      non-recoverability determination made by the Master Servicer. 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 Securities
      Administrator 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 Securities Administrator 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
      Securities Administrator 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 Securities Administrator shall be
      entitled to conclusively rely upon any determination by the Master Servicer
      that
      an Advance, if made, would constitute a non-recoverable advance. The Master
      Servicer and each Servicer shall be entitled to be reimbursed from the
      Collection Account for all Advances made by it as provided in Section
      4.02.

     

    (b)           In
      the event that the Master Servicer fails for any reason to make an Advance
      required to be made pursuant to Section 5.04(a) on or before the Deposit Date,
      the Securities Administrator, 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 or any Servicer that would
      have been deposited in such Certificate Account over (b) the amount of any
      Advance made by the Master Servicer or such Servicer with respect to such
      Distribution Date; provided, however, that the Securities Administrator 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 Securities
      Administrator 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.

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

                Account.

            

    

     

    (a)           No
      later than the Closing Date, the Securities Administrator shall establish and
      maintain a segregated trust account that is an Eligible Account, which shall
      be
      titled “Funding Account, Wells Fargo Bank, N.A., as securities administrator, in
      trust for the registered holders of Structured Adjustable Rate Mortgage Loan
      Trust Mortgage Pass-Through Certificates Series 2006-3” (the “Funding Account”).
      The Securities Administrator shall, promptly upon receipt, deposit in the
      Funding Account and retain therein the Funding Amount remitted on the Closing
      Date to the Securities Administrator by the Depositor. Funds deposited in the
      Funding Account shall be held in trust by the Securities Administrator on behalf
      of the Certificateholders for the uses and purposes set forth herein. On the
      Distribution Date in April 2006, the Securities Administrator will withdraw
      from
      the Funding Account an amount equal to the Funding Amount. The Securities
      Administrator shall pay the Funding Amount with respect to Pool 1 and Pool
      4 to
      the Certificateholders in accordance with the priorities set forth in Section
      5.02 as if such amounts were included in the Available Distribution Amounts
      of
      Pool 1 and Pool 4; provided, however, that the Securities Administrator shall
      not be entitled to any payment pursuant to Section 5.02(a)(i) with respect
      to
      the Funding Amount.

     

    (b)           The
      Securities Administrator will invest funds deposited in the Funding Account
      in
      Eligible Investments as directed in writing by the Depositor (provided that
      if
      the Securities Administrator does not receive written direction from the
      Depositor, the amounts in the Funding Account shall not be invested) with a
      maturity date no later than the Business Day preceding the first Distribution
      Date. For federal income tax purposes, the Depositor shall be the owner of
      the
      Funding Account and shall report all items of income, deduction, gain or loss
      arising therefrom. At no time will the Funding Account be an asset of any of
      the
      REMICs provided for herein. All income and gain realized from investment of
      funds deposited in the Funding Account shall be for the sole and exclusive
      benefit of the Depositor and shall be remitted by the Securities Administrator
      to the Depositor within eight (8) Business Days of the first Distribution Date.
      The Depositor shall deposit in the Funding Account the amount of any net loss
      incurred in respect of any such Eligible Investment immediately upon realization
      of such loss.

     

    (c)           On
      the Distribution Date in April 2006, any amounts remaining on deposit in the
      Funding Account after withdrawals pursuant to paragraph (a) above shall be
      withdrawn by the Securities Administrator and paid to the Depositor or its
      designee and the Securities Administrator shall terminate the Funding Account
      on
      such first Distribution Date.

    (d)           For
      purposes of computations throughout this Agreement (other than for purposes
      of
      computing any fee or the Net WAC of any Pool or portion thereof), (i) Pool
      1
      shall be deemed to include a certain Mortgage Loan with a Scheduled Principal
      Balance as of the Cut-off Date of $92,000.00 that is prepaid in full on the
      Closing Date such that its Scheduled Principal Balance for all Distribution
      Dates is $0 and (ii) Pool 4 shall be deemed to include certain Mortgage Loans
      with a Scheduled Principal Balance as of the Cut-off Date of $12,875,119.75
      that
      are prepaid in full on the Closing Date such that their Scheduled Principal
      Balance for all Distribution Dates is $0.

    CONCERNING
      THE TRUSTEE AND THE SECURITIES ADMINISTRATOR; 

    EVENTS
      OF
      DEFAULT

     

    
      	 	
              Section
                6.01.

            	
              Duties
                of Trustee and Securities Administrator.

            

    

     

    (a)           The
      Trustee, except during the continuance of an Event of Default (of which a
      Responsible Officer of the Trustee shall have actual knowledge), and the
      Securities Administrator undertakes to perform such duties and only such duties
      as are specifically set forth in this Agreement. Any permissive right of the
      Trustee or the Securities Administrator provided for in this Agreement shall
      not
      be construed as a duty of the Trustee or the Securities Administrator. If an
      Event of Default (of which a Responsible Officer of the Trustee or the
      Securities Administrator shall have actual knowledge) has occurred and has
      not
      otherwise been cured or waived, the Trustee or the Securities Administrator
      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 Securities Administrator is acting as Master Servicer,
      in
      which case it shall use the same degree of care and skill as the Master Servicer
      hereunder.

     

    (b)           Each
      of the Trustee and the Securities Administrator, upon receipt of all
      resolutions, certificates, statements, opinions, reports, documents, orders
      or
      other instruments furnished to the Trustee or the Securities Administrator
      which
      are specifically required to be furnished pursuant to any provision of this
      Agreement, shall examine them to determine whether they are in the form required
      by this Agreement; provided, however, that neither the Trustee nor the
      Securities Administrator shall 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, to the Trustee or the
      Securities Administrator, as applicable, pursuant to this Agreement, and neither
      the Trustee nor the Securities Administrator shall be required to recalculate
      or
      verify any numerical information furnished to the Trustee or the Securities
      Administrator pursuant to this Agreement.

     

    (c)           Neither
      the Trustee nor the Securities Administrator shall have any liability arising
      out of or in connection with this Agreement, except for its negligence or
      willful misconduct, except as may be otherwise expressly set forth herein.
      No
      provision of this Agreement shall be construed to relieve the Trustee or the
      Securities Administrator from liability for its own negligent action, its own
      negligent failure to act or its own willful misconduct; provided, however,
      that:

     

    
      
        
        

      

      
        89

        
          

        

      

      
        
        

      

    

    (i)           Neither
      the Trustee nor the Securities Administrator shall 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 Holders of Certificates as
      provided in Section 6.18 hereof;

     

    (ii)           For
      all purposes under this Agreement, the Trustee shall not be deemed to have
      notice of any Event of Default 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 Corporate Trust Office, and
      such notice references the Holders of the Certificates and this
      Agreement;

     

    (iii)           For
      all purposes under this Agreement, the Securities Administrator 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
      Securities Administrator when required to do so) unless a Responsible Officer
      of
      the Securities Administrator has actual knowledge thereof or unless written
      notice of any event which is in fact such a default is received by the
      Securities Administrator at the address provided in Section 11.07, and such
      notice references the Holders of the Certificates and this Agreement;
      and

     

    (iv)           With
      respect to amounts that would be treated as “unanticipated expenses” within the
      meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii) if paid or reimbursed
      by the REMICs hereunder, no provision of this Agreement shall require the
      Trustee or the Securities Administrator to expend or risk its own funds or
      otherwise incur any financial liability in the performance of any of its duties
      hereunder, or in the exercise of any of its rights or powers, if it shall have
      reasonable grounds for believing that 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 or the Securities Administrator to perform, or be responsible for
      the manner of performance of, any of the obligations of the Master Servicer
      under this Agreement except, with respect to the Securities Administrator,
      during such time, if any, as the Securities Administrator 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.

     

    (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 use its best efforts to 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, (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)           Neither
      the Trustee or the Securities Administrator shall 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 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 the Securities Administrator, as
      applicable, or exercising any trust or power conferred upon the Trustee or
      the
      Securities Administrator, as applicable, under this Agreement.

     

    (f)           Neither
      the Trustee nor the Securities Administrator shall be held liable by reason
      of
      any insufficiency in any account (including without limitation the Certificate
      Account) held by or on behalf of the Trustee or the Securities Administrator
      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).

     

    (g)           Except
      as otherwise provided herein, neither the Trustee nor the Securities
      Administrator shall 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 re-recording, re-filing or re-depositing 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 delivered to the Trustee or the Securities Administrator
      pursuant to this Agreement believed by the Trustee or the Securities
      Administrator, as applicable, to be genuine and to have been signed or presented
      by the proper party or parties.

     

    (h)           Neither
      the Securities Administrator nor the Trustee shall 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 or the Securities Administrator, as applicable,
      unless it shall be proved that the Trustee or the Securities Administrator,
      as
      applicable, was negligent in ascertaining the pertinent facts.

     

    (i)           Notwithstanding
      anything in this Agreement to the contrary, neither the Securities Administrator
      nor the Trustee shall 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 or the Securities Administrator, as applicable, has been
      advised of the likelihood of such loss or damage and regardless of the form
      of
      action, provided,
      however,
      that
      this Subsection 6.01(i) shall not apply in connection with any failure by the
      Securities Administrator to comply with the provisions of Subsections 6.01(k)
      and (l) hereof and Subsections 9.25(a) and (b) hereof.

     

    (j)           Neither
      the Securities Administrator nor the Trustee shall be responsible for the acts
      or omissions of the other or 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.

      Securities Administrator 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
      Securities Administrator, 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.

     

    (l)           The
      Trustee and the Securities Administrator shall each 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 or the
      Securities Administrator, as applicable, of the type described in Item 1117
      (§
229.1117) of Regulation AB, and (ii) of any merger, consolidation or sale of
      substantially all of the assets of the Trustee or the Securities Administrator,
      as applicable, and (iii) if the Trustee or the Securities Administrator, as
      applicable, shall become (but only to the extent not previously disclosed)
      at
      any time an affiliate of any of the parties listed on Exhibit R hereto. On
      or
      before March 1st
      of each
      year, the Depositor shall distribute the information on Exhibit R to the Trustee
      and the Securities Administrator.

    Except
      as
      otherwise provided in Section 6.01:

     

    (i)           Each
      of the Trustee and the Securities Administrator may request, and may rely and
      shall be protected in acting or refraining from acting upon any resolution,
      Officer’s Certificate, certificate of auditors, Opinion of Counsel 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

    (ii)          Each
      of the Trustee and the Securities Administrator 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)         Neither
      the Trustee nor the Securities Administrator shall 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, neither the Trustee

      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 Holders of at least a majority in Class
      Principal Amount (or Class Notional Amount) of each Class of Certificates;
      provided, however, that, if the payment within a reasonable time to the Trustee
      or the Securities Administrator, as applicable, 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 or the
      Securities Administrator, as applicable, may require reasonable indemnity
      against such expense or liability or payment of such estimated expenses as
      a
      condition to proceeding. The reasonable expense thereof shall be paid by the
      Holders requesting such investigation and if not reimbursed by the requesting

      any
      state in which a property securing a Mortgage Loan is located or in any state

      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

      appointee an agent of the Trustee. The obligation of the Securities
      Administrator to make Advances pursuant to Section 5.04 and 6.14 hereof shall

      however, that prior to the appointment hereunder of any such co-trustee,
      separate trustee, or custodian, 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

    (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;

    (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.

     

    (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. The Trustee shall not be responsible
      for any action or inaction of any separate trustee, co-trustee or custodian.
      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
      Trust Fund shall pay the reasonable compensation of the co-trustees to the
      extent, and in accordance with the standards, specified in Section 6.12 hereof
      (which compensation shall not reduce any compensation payable to the Trustee

              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. The Trustee
      hereby appoints the Securities Administrator to act as the initial
      Authenticating Agent, and the Securities Administrator hereby accepts such
      appointment. 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.

    (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 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 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 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 to the extent provided in Section
      6.12.

              Indemnification
                of Trustee and Securities Administrator.

            

    

     

    The
      Trustee and the Securities Administrator and their 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, 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 or under the Certificates, the Mortgage Loan Sale Agreement,
      any Custodial Agreement or any Servicing 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 or the Securities Administrator, as
      applicable, shall have given the Depositor, the Master Servicer and the Holders
      written notice thereof promptly after a Responsible Officer of the Trustee
      or
      the Securities Administrator, as applicable, shall have knowledge thereof;
      provided that failure to so notify shall not relieve the Trust Fund of the
      obligation to indemnify the Trustee or the Securities
      Administrator;

     

    
      
        
        

      

      
        99

        
          

        

      

      
        
        

      

    

    (ii)           while
      maintaining control over its own defense, the Trustee or the Securities
      Administrator, as applicable, 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 or the Securities
      Administrator, as applicable, entered into without the prior consent of the
      Depositor, which consent shall not be unreasonably withheld; and

     

    (iv)           any
      such loss, liability or expense indemnified by the Trust Fund must constitute
      an
“unanticipated expense” within the meaning of Treasury Regulations Section
      1.860G-1(b)(3)(ii).

     

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

    The
      Securities Administrator shall be entitled to (a) the Securities Administrator
      Fee, and is authorized to pay itself the amount of income or gain earned from
      investment of funds in the Certificate Account and (b) reimbursement of all
      reasonable expenses, disbursements and advancements incurred or made by the
      Securities Administrator in accordance with this Agreement (including fees
      and
      expenses of its counsel and all persons not regularly in its employment), except
      any such expenses, disbursements and advancements that either (i) arise from
      its
      negligence, bad faith or willful misconduct or (ii) do not constitute
“unanticipated expenses” within the meaning of Treasury Regulations Section
      1.860G-1(b)(3)(ii). The Trustee shall be paid the Trustee Fee by the Securities
      Administrator from its own funds, as separately agreed with the Securities
      Administrator. Each 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.

      Administrator 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 or Securities Administrator 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 or Securities Administrator
      shall not have timely received amounts to be remitted with respect to the
      Mortgage Loans from the Master Servicer, the Trustee or Securities Administrator
      shall request the Master Servicer to make such distribution as promptly as
      practicable or legally permitted. If the Trustee or Securities Administrator
      shall subsequently receive any such amount, it may withdraw such
      request.

    If
      an
      Event of Default described in clauses (i) through (xi) 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 6.14, 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, 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 (xii) of Section 6.14(a) 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 (xii) of Section 6.14(a), the Trustee, by notice in writing to the Master
      Servicer, shall promptly terminate all of 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 Securities Administrator upon
      receipt of written notice by the Securities Administrator from the Trustee
      pursuant to and under the terms of this Agreement; and the Securities
      Administrator 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 and the Securities Administrator
      in effecting the termination of the defaulting Master Servicer’s
      responsibilities and rights hereunder as Master Servicer including, without
      limitation, notifying Servicers of the assignment of the master servicing
      function and providing the Securities Administrator or its designee all
      documents and records in electronic or other form reasonably requested by it
      to
      enable the Securities Administrator or its designee to assume the defaulting
      Master Servicer’s functions hereunder and the transfer to the Securities
      Administrator 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 shall bear all costs of a master servicing transfer, including but
      not limited to those of the Trustee and Securities Administrator 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 Securities Administrator 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 servicing from the predecessor Master 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 Securities
      Administrator to correct any errors or insufficiencies in the servicing data
      or
      otherwise to enable the Securities Administrator 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
      Securities Administrator shall be entitled to withdraw such reimbursement from
      amounts on deposit in the Certificate Account pursuant to Section 4.04; provided
      that the terminated Master Servicer shall reimburse the Trust Fund for any
      such
      expense incurred by the Trust Fund; and provided, further, that the Trustee
      shall decide whether and to what extent it is in the best interest of the
      Certificateholders to pursue any remedy against any party obligated to make
      such
      reimbursement.

      
        
          
          

        

        
          103

          
            

          

        

        
          
          

        

      

    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(i), (ii), (iii), (iv), (v), (vi), (vii) and (x) 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
      or
      Securities Administrator has actual knowledge,
      the
      Trustee or Securities Administrator, as applicable, upon becoming aware of
      the
      occurrence thereof through the proper execution of its duties under this
      Agreement, shall promptly notify the Securities Administrator or Trustee and
      the
      Rating Agencies of the nature and extent of such Event of Default. The Trustee
      or the Securities Administrator shall immediately give written notice to the
      Master Servicer upon such Master Servicer’s failure to remit funds on the
      Deposit Date.

     

    (b)           On
      and after the time the Master Servicer receives a notice of termination from
      the
      Trustee or Securities Administrator 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 and within a period of time not to exceed
      90
      days after the Securities Administrator receives written notice from the Trustee
      pursuant to Section 6.14(a) or Section 9.28, the Securities Administrator,
      unless another master servicer 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 or the Trustee’s failure to provide information required
      by this Agreement shall not be considered a default by the Securities
      Administrator hereunder. In addition, the Securities Administrator shall have
      no
      responsibility for any act or omission of the Master Servicer prior to the
      issuance of any notice of termination and within a period of time not to exceed
      90 days after the Securities Administrator receives written notice from the
      Trustee pursuant to Section 6.14(a) or Section 9.28, as applicable. The
      Securities Administrator shall have no liability relating to the representations
      and warranties of the Master Servicer set forth in Section 9.14. In the
      Securities Administrator’s capacity as such successor, the Securities
      Administrator shall have the same limitations on liability herein granted to
      the
      Master Servicer. As compensation therefor, the Securities Administrator shall
      be
      entitled to receive all compensation payable to the Master Servicer under this
      Agreement, including the Master Servicing Fee and the compensation described
      in
      Section 9.21. The Securities Administrator 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 Securities Administrator to
      correct any errors or insufficiencies in the master servicing data or otherwise
      to enable the Securities Administrator to master service the Mortgage Loans
      properly and effectively.

    (c)           Notwithstanding
      the above, the Securities Administrator may, if it shall be unwilling to
      continue to so act, or shall, if it is unable to so act, request the Trustee
      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 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. Any entity
      designated by the Trustee or the Securities Administrator as a successor master
      servicer may be an Affiliate of the Trustee or the Securities Administrator;
      provided, however, that, unless such Affiliate meets the net worth requirements
      and other standards set forth herein for a successor master servicer, the
      Trustee or the Securities Administrator, 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 or the Securities
      Administrator 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, the Securities
      Administrator 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, the Securities Administrator 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 Securities Administrator
      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, the
      Securities Administrator 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, the Securities Administrator 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
      Securities Administrator as required by this Agreement or (iv) restrictions
      imposed by any regulatory authority having jurisdiction over the Master
      Servicer.

    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 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.

      or
      more of the Aggregate Voting Interests of Certificateholders 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.
      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.

      termination of the Master Servicer or appointment of a successor to the Master

      promptly mail notice thereof by first class mail to the Trustee and the
      Certificateholders at their respective addresses appearing on the Certificate
      Register. 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 the Securities Administrator 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.

    Subject

      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,
      unless such Certificateholders 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 or be unjustly
      prejudicial to the non-assenting Certificateholders.

      of
      the Trustee, the Trustee shall not be deemed to have knowledge of any failure
      of

      of

      as required by the Exchange Act. The Securities Administrator shall file each
      Form 10-D with a copy of the related Distribution Date Statement attached
      thereto. Any disclosure in addition to the Distribution Date Statement that
      is
      required to be included on Form 10-D (“Additional Form 10-D Disclosure”) shall
      be determined and prepared by and at the direction of the Depositor pursuant
      to

    (ii)           As
      set forth on Exhibit P-1 hereto, within five calendar days after the related
      Distribution Date, (A) certain parties to the Structured Adjustable Rate
      Mortgage Loan Trust 2006-3 transaction shall be required to provide to the
      Securities Administrator and the Depositor, to the extent known by a responsible
      officer thereof, in EDGAR-compatible form (which may be Word or Excel documents
      easily convertible to EDGAR format), or in such other form as otherwise agreed
      upon by the Securities Administrator and such party, the form and substance
      of
      any Additional Form 10-D Disclosure, if applicable, and include with such
      Additional Form 10-D Disclosure, an Additional Disclosure Notification in the
      form attached hereto as Exhibit P-4, and (B) the Depositor will approve, as
      to
      form and substance, or disapprove, as the case may be, the 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 Securities
      Administrator 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 Securities Administrator 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 Securities Administrator. If a Form 10-D cannot be filed on time
      or
      if a previously filed Form 10-D needs to be amended, the Securities
      Administrator will follow the procedures set forth in subsection (g)(ii) of
      this
      Section 6.20. Promptly (but no later than one Business Day) after filing with
      the Commission, the Securities Administrator 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 Securities Administrator of its duties
      under this Section 6.20(d) 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(d). The Securities
      Administrator 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 Securities
      Administrator’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.

      Servicer, each Custodian, each Additional Servicer, the Master Servicer, each
      Subservicer, each Subcontractor, any Servicing Function Participant and the
      Securities Administrator (each, a “Reporting Servicer”), as described under
      Section 9.25(a) hereof and in each Servicing Agreement and Custodial Agreement,
      and (II) if any Reporting Servicer’s report on assessment of compliance with
      servicing criteria described under Section 9.25(a) hereof or in any Servicing
      Agreement or Custodial Agreement identifies any material instance of
      noncompliance, disclosure identifying such instance of noncompliance, or if
      any
      Reporting Servicer’s report on assessment of compliance with servicing criteria
      described under Section 9.25(a) hereof or in the any Servicing Agreement or
      Custodial Agreement is not included as an exhibit to such Form 10-K, disclosure
      that such report is not included and an explanation why such report is not

      in
      any Servicing Agreement or Custodial Agreement identifies any material instance
      of noncompliance, disclosure identifying such instance of noncompliance, or
      if

      above that is required to be included on Form 10-K (“Additional Form 10-K
      Disclosure”) shall be determined and prepared by and at the direction of the
      Depositor pursuant to the following paragraph and the Securities Administrator
      will have no duty or liability for any failure hereunder to determine or prepare
      any Additional Form 10-K Disclosure, except as set forth in the next paragraph.
      

     

    (ii)           As
      set forth on Exhibit P-2 hereto, no later than March 15 of each year that the
      Trust Fund is subject to the Exchange Act reporting requirements, commencing
      in
      2007, (A) certain parties to the Structured Adjustable Rate Mortgage Loan Trust
      2006-3 transaction shall be required to provide to the Securities Administrator
      and the Depositor, to the extent known by a responsible officer thereof, in
      EDGAR-compatible form (which may be Word or Excel documents easily convertible

      Securities Administrator and such party, the form and substance of any
      Additional Form 10-K Disclosure, if applicable and include with such Additional
      Form 10-K Disclosure, an Additional Disclosure Notification in the form attached
      hereto as Exhibit P-4, and (B) the Depositor will approve, as to form and
      substance, or disapprove, as the case may be, the inclusion of the Additional
      Form 10-K Disclosure on Form 10-K. The Securities Administrator has no duty
      under this Agreement to monitor or enforce the performance by the parties listed
      on Exhibit P-2 of their duties under this paragraph or proactively solicit
      or
      procure from such parties any Form 10-K Disclosure Information. The Sponsor
      will
      be responsible for any reasonable fees and expenses assessed or incurred by
      the
      Securities Administrator in connection with including any Additional Form 10-K
      Disclosure on Form 10-K pursuant to this paragraph.

      electronically a draft copy of the Form 10-K to the Exchange Act Signing Party
      for review and approval. If the Master Servicer is the Exchange Act Signing
      Party and the Form 10-K includes Additional Form 10-K Disclosure, then the
      Form
      10-K shall also be electronically distributed to the Depositor for review and

      Act Signing Party shall sign the Form 10-K and return an electronic or fax
      copy
      of such signed Form 10-K (with an original executed hard copy to follow by
      overnight mail) to the Securities Administrator. If a Form 10-K cannot be filed
      on time or if a previously filed Form 10-K needs to be amended, the Securities
      Administrator will follow the procedures set forth in subsection (g) of this
      Section 6.20. Promptly (but no later than one Business Day) after filing with
      the Commission, the Securities Administrator will make available on its internet
      website a final executed copy of each Form 10-K. The parties to this Agreement
      acknowledge that the performance by the Securities Administrator of its duties
      under this Section 6.20(e) related to the timely preparation and filing of
      Form
      10-K is contingent upon such parties (and any Additional Servicer or Servicing
      Function Participant) strictly observing all applicable deadlines in the
      performance of their duties under this Section 6.20(e), Section 9.25(a), Section
      9.25(b) and Section 9.26. The Securities Administrator 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-K, where such
      failure results from the Securities Administrator’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-K, not
      resulting from its own negligence, bad faith or willful misconduct.

     

    (iv)           Each
      Form 10-K shall include the Sarbanes-Oxley Certification. The Securities
      Administrator and, if the Depositor is the Exchange Act Signing Party, the
      Master Servicer, shall, and the Securities Administrator and the Master Servicer
      (if applicable) shall cause any Servicing Function Participant engaged by it
      to,
      provide to the Person who signs the Sarbanes-Oxley Certification (the
“Certifying Person”), by March 15 of each year in which the Trust Fund is
      subject to the reporting requirements of the Exchange Act, a certification
      (each, a “Back-Up Certification”), in the form attached hereto as Exhibit Q,
      upon which the Certifying Person, the entity for which the Certifying Person
      acts as an officer, and such entity’s officers, directors and Affiliates
      (collectively with the Certifying Person, “Certification Parties”) can
      reasonably rely. The senior officer of the Exchange Act Signing Party shall
      serve as the Certifying Person on behalf of the Trust Fund. In the event the
      Master Servicer, the Securities Administrator or any Servicing Function
      Participant engaged by such parties is terminated or resigns pursuant to the
      terms of this Agreement, such party or Servicing Function Participant shall
      provide a Back-Up Certification to the Certifying Person pursuant to this
      Section 6.20(e)(iv) with respect to the period of time it was subject to this
      Agreement.

     

    (v)           Each
      person (including their officers or directors) that signs any Form 10-K
      Certification shall be entitled to indemnification from the Trust Fund for
      any
      liability or expense incurred by it in connection with such certification,
      other
      than any liability or expense attributable to such Person’s own bad faith,
      negligence or willful misconduct. The provisions of this subsection shall
      survive any termination of this Agreement and the resignation or removal of
      such
      Person.

    (f)           Reports
      Filed on Form 8-K.

     

    (i)           Within
      four Business Days after the occurrence of an event requiring disclosure on
      Form
      8-K (each such event, a “Reportable Event”), and if requested by the Depositor,
      the Securities Administrator shall prepare and file on behalf of the Trust
      Fund
      any Form 8-K, as required by the Exchange Act, provided
      that the
      Depositor shall file the initial Form 8-K in connection with the issuance of
      the
      Certificates. Any disclosure or information related to a Reportable Event or
      that is otherwise required to be included on Form 8-K (“Form 8-K Disclosure
      Information”) shall be determined and prepared by and at the direction of the
      Depositor pursuant to the following paragraph and the Securities Administrator
      will have no duty or liability for any failure hereunder to determine or prepare
      any Form 8-K Disclosure Information or any Form 8-K, except as set forth in
      the
      next paragraph. 

     

    

    (ii)           As
      set forth on Exhibit P-3 hereto, for so long as the Trust Fund is subject to
      the
      Exchange Act reporting requirements, no later than Noon New York City time
      on
      the 2nd Business Day after the occurrence of a Reportable Event (A) certain
      parties to the Structured Adjustable Rate Mortgage Loan Trust 2006-3 transaction
      shall be required to provide to the Securities Administrator and the Depositor,
      to the extent known by a responsible officer thereof, in EDGAR-compatible form
      (which may be Word or Excel documents easily convertible to EDGAR format),
      or in
      such other form as otherwise agreed upon by the Securities Administrator and
      such party, the form and substance of any Form 8-K Disclosure Information,
      if
      applicable, and include with such Form 8-K Disclosure Information, an Additional
      Disclosure Notification in the form attached hereto as Exhibit P-4, and (B)
      the
      Depositor will approve, as to form and substance, or disapprove, as the case
      may
      be, the inclusion of the Form 8-K Disclosure Information. The Securities
      Administrator has no duty under this Agreement to monitor or enforce the
      performance by the parties listed on Exhibit P-3 of their duties under this
      paragraph or proactively solicit or procure from such parties any Form 8-K
      Disclosure Information. The Sponsor will be responsible for any reasonable
      fees
      and expenses assessed or incurred by the Securities Administrator in connection
      with including any Form 8-K Disclosure Information on Form 8-K pursuant to
      this
      paragraph. 

     

    

    (iii)           After
      preparing the Form 8-K, the Securities Administrator 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 shall sign the Form 8-K and return an electronic
      or
      fax copy of such signed Form 8-K (with an original executed hard copy to follow
      by overnight mail) to the Securities Administrator. If a Form 8-K cannot be
      filed on time or if a previously filed Form 8-K needs to be amended, the
      Securities Administrator will follow the procedures set forth in subsection
      (g)
      of this Section 6.20. Promptly (but no later than one Business Day) after filing
      with the Commission, the Securities Administrator will, make available on its
      internet website a final executed copy of each Form 8-K prepared and filed
      by it
      pursuant to this Section 6.20(f). The parties to this Agreement acknowledge
      that
      the performance by the Securities Administrator of its duties under this Section
      6.20(f) 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(f). The Securities Administrator 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 8-K,
      where such failure results from the Securities Administrator’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.

      to do so under applicable law, unless otherwise directed by the Depositor,
      the
      Securities Administrator 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 Securities Administrator 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 Securities
      Administrator will promptly notify the Depositor. In the case of Form 10-D
      and
      10-K, the parties to this Agreement and each 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 Securities
      Administrator 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 Securities Administrator will notify
      the Depositor and each Servicer (provided that each Servicer will only be
      notified in the event of an additional disclosure item) 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 Securities Administrator of its duties
      under this Section 6.20(g) 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 Securities
      Administrator 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 Securities Administrator’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.

      party that signs any Exchange Act report that the Securities Administrator
      is
      required to file shall provide to the Securities Administrator 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
      Securities Administrator the original executed signature page for such report.
      In addition, each of the parties agrees to provide to the Securities
      Administrator such additional information related to such party as the
      Securities Administrator 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.

      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 Securities
      Administrator, 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 Securities Administrator of any
      such change.

    (a)           The
      respective obligations and responsibilities of the Trustee, the Securities
      Administrator and the Master Servicer created hereby (other than the obligation
      of the Trustee to make payments to Certificateholders as set forth in Section

      Securities Administrator for deposit into the Certificate Account pursuant
      to
      Section 4.01 and the obligations of the Master Servicer to the Securities
      Administrator and the Trustee pursuant to Sections 9.10 and 9.14), shall
      terminate on the earlier 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 and (ii) the sale of all remaining property held by the Trust Fund
      in
      accordance with Section 7.01(b); 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 after the date on which (x) the total Scheduled
      Principal Balance of the Mortgage Loans in Pools 1 through 3 is less than 10%
      of

      Pool
      3 (in the aggregate) as of the Cut-off Date or (y) the total Scheduled Principal
      Balance of the Mortgage Loans in Pools 4 is less than 10% of the Scheduled
      Principal Balance of the Mortgage Loans in Pool 4 as of the Cut-off Date, the

      unreasonably withheld), may, upon written direction to the Trustee, cause the
      Trustee to sell (or arrange for the sale of) the assets of (x) Pool 1, Pool
      2
      and Pool 3 (in the aggregate) or (y) Pool 4, and thereby effect the retirement
      of the related Certificates. Upon the repurchase of such Mortgage Loans, the
      Master Servicer shall, upon written direction to the Trustee, cause each of
      REMIC I-1, REMIC I-2 and REMIC I-3 (in the case of a sale of the assets
      described in clause (x) above) or each of REMIC II-1 and REMIC II-2 (in the
      case
      of a sale of the assets described in clause (y) above) to adopt a plan of
      complete liquidation pursuant to Section 7.03 hereof to sell all of its
      property. The property of the applicable Pool or Pools shall be sold at a price
      (the “Repurchase Price”) equal to: (i) 100% of the unpaid principal balance of
      each Mortgage Loan in such Pool or Pools on the day of such purchase plus
      interest accrued thereon at the applicable Mortgage Rate with respect to any
      such Mortgage Loan to the Due Date in the Due Period immediately preceding
      such
      Distribution Date, (ii) the fair market value of any applicable REO Property
      and
      any other applicable property (reduced, in the case of REO Property, by (x)
      reasonably anticipated disposition costs and (y) any amount by which the fair
      market value as so reduced exceeds the outstanding principal balance of the
      related Mortgage Loan), such fair market value to be determined by an appraiser
      or appraisers appointed by the Master Servicer with the consent of the Trustee
      and (iii) any unreimbursed Servicing Advances with respect to each applicable
      Mortgage Loan. The Master Servicer and each Servicer (or the Trustee, if
      applicable) shall be reimbursed from the Repurchase Price for any Mortgage
      Loan
      or related REO Property for any Advances or Servicing Advances made with respect
      to the Mortgage Loans that are reimbursable to the Master Servicer under this
      Agreement or to each Servicer under the related Servicing Agreement (or to
      the
      Trustee hereunder), together with any accrued and unpaid compensation and any
      other amounts due to the Master Servicer and the Trustee hereunder or the
      Custodians or the Servicers under their respective Custodial or Servicing
      Agreements, provided that any such compensation or other amount to be paid
      to
      the Custodians and any such other amounts to be paid to the Servicers are
“unanticipated expenses” within the meaning of Treasury Regulation Section
      1.860G-1(b)(3)(ii). The Securities Administrator shall distribute the assets
      of
      the applicable Pool or Pools on the Distribution Date on which the repurchase
      occurred. Upon the repurchase of all of the Mortgage Loans, the Trust Fund
      shall
      terminate in accordance with the terms of this Agreement.

      pursuant to such Section 7.01(b)) or (y) upon the final payment or other
      liquidation of the last Mortgage Loan or REO Property in the Trust Fund. Such
      notice shall specify (A) the Distribution Date upon which final distribution
      on
      the Certificates of all amounts required to be distributed to Certificateholders
      pursuant to Section 5.02 will be made upon presentation and surrender of the
      Certificates at the Corporate Trust Office, and (B) that the Record Date
      otherwise applicable to such Distribution Date is not applicable, distribution
      being made only upon presentation and surrender of the Certificates at the
      office or agency of the Securities Administrator therein specified. The
      Securities Administrator shall give such notice to the Trustee, the Master
      Servicer, the Depositor and the Certificate Registrar at the time such notice
      is
      given to Holders of the Certificates. Upon any such termination of the entire
      Trust Fund, 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 Securities Administrator’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 Securities Administrator 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 Securities Administrator 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 Securities
      Administrator 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 and the Securities Administrator
      in
      connection with any termination or liquidation of the Trust Fund (or a Mortgage
      Group thereof) shall be paid from proceeds received from the liquidation of
      the
      Trust Fund, but only to the extent that such expenses constitute “unanticipated
      expenses” within the meaning of Treasury Regulations Section
      1.860G-1(b)(3)(ii).

    (a)           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 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)           in
      the case of a sale of the assets of Mortgage Group I:

     

    (A)           The
      Trustee shall sell all of the assets of Mortgage Group I for cash and, within
      90
      days of such sale, shall distribute the proceeds of such sale to the Group
      I
      Certificateholders in complete liquidation of REMIC I-1, REMIC I-2 and REMIC
      I-3; and

     

    (B)           The
      Securities Administrator shall attach a statement to the final Federal income
      tax return for each of REMIC I-1, REMIC I-2 and REMIC I-3 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;
      and

    (ii)           in
      the case of a sale of the assets of Mortgage Group II:

     

    (A)           The
      Trustee shall sell all of the assets of Mortgage Group II for cash and, within
      90 days of such sale, shall distribute the proceeds of such sale to the Group
      II
      Certificateholders in complete liquidation of REMIC II-1 and REMIC II-2;
      and

     

    (B)           The
      Securities Administrator shall attach a statement to the final Federal income
      tax return for each of REMIC II-1 and REMIC II-2 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.

     

    (b)           By
      its acceptance of a Residual Certificate, each Holder thereof hereby (i)
      authorizes the Trustee to take the action described in paragraph (a) above
      and
      (ii) agrees to take such other action as may be necessary to facilitate
      liquidation of any REMIC created under this Agreement, which authorization
      shall
      be binding upon all successor Residual Certificateholders.

    (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) 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.

                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 Securities Administrator, 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 Securities Administrator shall, within five Business Days
      after the receipt of such application, afford such Applicants reasonable access
      during the normal business hours of the Securities Administrator to the most
      recent list of Certificateholders held by the Securities Administrator 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

      Administrator, the Master Servicer, the Certificate Registrar and the Trustee
      that neither the Depositor, the Securities Administrator, the Master Servicer,
      the Certificate Registrar nor 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.

    (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 Securities Administrator 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, the Securities Administrator and Master
      Servicer, if made in the manner provided in this Section. Each of the Trustee,
      the Securities Administrator and Master Servicer shall promptly notify the
      others of receipt of any such instrument by it, and shall promptly forward
      a
      copy of such instrument to the others.

    (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 Securities Administrator, the Master Servicer and
      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 therefore or in lieu thereof,
      in
      respect of anything done, omitted or suffered to be done by the Trustee, the
      Securities Administrator or the Master Servicer in reliance thereon, whether
      or
      not notation of such action is made upon such Certificate.

      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 Errors and Omissions Insurance
      Policy and the Fidelity Bond shall be in such form and amount that would meet
      the requirements of FNMA or FHLMC if it were the purchaser of the Mortgage
      Loans. The Master Servicer shall (i) require each Servicer to maintain an Errors
      and Omissions Insurance Policy and a Fidelity Bond in accordance with the
      provisions of the applicable Servicing Agreement, (ii) cause each Servicer
      to

      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 the certificates and notices referred to in clause (ii) to the Trustee upon
      its 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
      Securities Administrator for deposit into the Certificate Account. Any amounts
      relating to the Mortgage Loans collected by any Servicer under any such bond
      or
      policy shall be remitted to the Master Servicer to the extent provided in the
      applicable Servicing Agreement.

      the Trustee, in its own name or in the name of any Servicer, 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 any REMIC included in the Trust
      Fund to fail to qualify as a REMIC or result in the imposition of any tax under
      Section 860F(a) or Section 860G(d) of the Code. 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 by the Master 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 furnish the Master
      Servicer or a Servicer, upon request, with any powers of attorney prepared
      by
      the Master Servicer or such 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.

    (b)           In
      master servicing and administering the Mortgage Loans, the Master Servicer
      shall
      employ procedures and exercise the same care that it customarily employs and
      exercises in 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 any Servicer to, in its discretion (i) waive any
      late payment charge (but not any Prepayment Penalty Amount, 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
      or
      cause to be made 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 Penalty Amount if (a) such Mortgage Loan is in default
      or default by the related Mortgagor is reasonably foreseeable, and such waiver
      would maximize recovery of total proceeds taking into account the value of
      such
      Prepayment Penalty Amount and the related Mortgage Loan or (b) the prepayment
      is
      not the result of a refinance 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 Penalty Amount and
      the
      related Mortgage Loan or (ii) the collection of the Prepayment Penalty Amount
      would be in violation of applicable laws or (iii) the collection of such
      Prepayment Penalty Amount 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 (which opinion shall, if
      provided by the Master Servicer, be an expense reimbursed, to the extent it
      is
      an unanticipated expense within the meaning of Treasury Regulation Section
      1.860G-1(b)(3)(ii) 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 Penalty Amount under clause (2)
      above.

              Servicing
                Agreements Between the Master Servicer and Servicers; Enforcement
                of
                Servicers’ 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 such actions taken
      or to be taken by a Servicer pursuant to a Servicing Agreement. Any fees, costs
      and expenses and other amounts payable to such Servicers shall be deducted
      from
      amounts remitted to the Master Servicer by the applicable Servicer (to the
      extent permitted by the applicable Servicing Agreement) and shall not be an
      obligation of the Trust, 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 related 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 the 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 the Servicer to take such
      action.

     

    (c)           The
      Master Servicer, for the benefit of the Trustee and the Certificateholders,
      shall enforce the obligations of each Servicer under the related Servicing
      Agreement, and shall use its reasonable best efforts to enforce the obligations
      of each Servicer under the related Servicing Agreement and shall, upon its
      obtaining actual knowledge of the failure of a Servicer to perform its
      obligations in accordance with the related Servicing Agreement, to the extent
      that the non-performance of any such obligations would have a material adverse
      effect on a Mortgage Loan, the Trust Fund or Certificateholders, terminate
      the
      rights and obligations of such Servicer thereunder to the extent and in the
      manner permitted by the related Servicing Agreement and either act as servicer
      of the related Mortgage Loans or enter into a 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 therefore initially only (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, to the extent that such
      amounts are insufficient to reimburse the Master Servicer for the costs of
      such
      enforcement or (iii) 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, filings or
      reports, in accordance with the terms hereof or as may be required by applicable
      law or regulation.

                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 any 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 shall
      deposit therein any collections of amounts received with respect to amounts
      due
      for taxes, assessments, water rates, Standard Hazard Insurance Policy premiums
      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 applicable Servicing Agreement. 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 has determined that the funds so advanced are
      recoverable from escrow payments, reimbursement pursuant to Section 4.02(v)
      or
      otherwise.

     

    (b)           Costs
      incurred by the Master Servicer or by 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 expenses within the meaning of Treasury Regulations Section
      1.860G-1(b)(3)(ii) shall be recoverable by the Master Servicer pursuant to
      Section 4.02(v).

              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 the related Servicer, the Master
      Servicer shall either act as Servicer of the related Mortgage Loans, or enter
      into a Servicing Agreement with a successor Servicer.

     

    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 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 respect of the related Mortgage Loans, 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.

    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 or
      arrangements. 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.

      and the Depositor shall not be deemed parties thereto and shall have no claims,
      rights, obligations, duties or liabilities with respect to such Servicer except
      as set forth in Section 9.10 hereof.

      receives written notice from the Trustee pursuant to Section 6.14 or Section
      9.28, as applicable, the Securities Administrator shall thereupon assume all
      of
      the rights and obligations of such Master Servicer hereunder and enforce the
      rights under each Servicing Agreement entered into with respect to the Mortgage
      Loans. The Securities Administrator, its designee or any successor master
      servicer appointed by the Securities Administrator or 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 Securities Administrator, and hereby agrees to indemnify and
      hold
      harmless the Securities Administrator from and against all costs, damages,
      expenses and liabilities (including reasonable attorneys’ fees) incurred by the
      Securities Administrator as a result of such liability or obligations of the
      Master Servicer and in connection with the Securities Administrator’s assumption

      Securities Administrator are created or increased as a result of negligent

      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,

      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,

      Property if it has determined, exercising its good faith business judgment

      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.

              Release
                of Mortgage Files.

            

    

     

    (a)           Upon
      (i) becoming aware of the payment in full of any Mortgage Loan, (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, or (iii) in the case of
      a
      Mortgage Loan as to which the related Mortgaged Property is located in
      California, receipt by the Master Servicer of notification from the applicable
      Servicer that the Servicer reasonably expects that payment in full will be
      received promptly, the Master Servicer will, or will cause the applicable
      Servicer to, promptly notify the Trustee (or the applicable Custodian) by a
      certification (which certification shall include a statement to the effect
      that
      all amounts received or to be 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 have been or will be so deposited) of a
      Servicing Officer and shall request the Trustee or the applicable Custodian,
      to
      deliver to the applicable Servicer the related Mortgage File. In lieu of sending
      a hard copy certification of a Servicing Officer, the Master Servicer may,
      or
      may cause the Servicer to, deliver the request for release in a mutually
      agreeable electronic format. To the extent that such a request, on its face,
      originates from a Servicing Officer, no signature shall be required. Upon
      receipt of such certification and request, the Trustee or the applicable
      Custodian, shall promptly release the related Mortgage File to the applicable
      Servicer and neither the Trustee nor the Custodian shall have any further
      responsibility with regard to such Mortgage File. The Master Servicer is
      authorized, and each Servicer, to the extent such authority is delegated to
      such
      Servicer by the Master Servicer under the applicable 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 therefore 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, or other
      legal proceedings relating to, any Mortgage Loan and in accordance with Accepted
      Servicing Practices and the applicable Servicing Agreement, the Trustee shall
      execute such pleadings, request for trustee’s sale or other documents as shall
      be prepared and furnished to the Trustee by the Master Servicer, or by a
      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 a Servicer, and delivery to the
      Trustee or the applicable Custodian, of a trust receipt signed by a Servicing
      Officer substantially in the form annexed hereto as Exhibit C or in the form
      annexed to the applicable Custodial Agreement as 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 Custodian,
      as
      applicable, when the need therefore 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
      herein above 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 or purposes of such delivery.

    (a)           The
      Master Servicer shall transmit, or 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 to be delivered to the Trustee. 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 by 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 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 applicable 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 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.

    (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 Securities Administrator 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 any 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
      laws.

      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.

    (a)           The
      Master Servicer hereby represents and warrants to the Depositor, the Securities
      Administrator 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 jurisdiction of its
      formation, 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;

      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;

      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 an FNMA- and FHLMC-
      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

      consents, approvals, authorizations and orders (if any) as have been
      obtained;

     

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

     

    (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.

     

    (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, the Securities Administrator
      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 resulting from 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). 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). It is understood
      and
      agreed that the enforcement of the obligation of the Master Servicer set forth
      in this Section to indemnify the Depositor, the Securities Administrator and
      the
      Trustee as provided in this Section constitutes the sole remedy (other than
      as
      set forth in Section 6.14) of the Depositor, the Securities Administrator 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, the
      Securities Administrator or the Trustee or notice thereof by any one of such
      parties to the other parties.

    (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). 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 of the Master Servicer respecting a breach by the
      Depositor of the representations and warranties in Sections 2.03(a)(i) through
      (vi).

     

    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) 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.

    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 related 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.

      to Section 4.01, any amounts collected by the Master Servicer, or by any
      Servicer, under any insurance policies maintained pursuant to this Section

      (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
      the Master Servicer’s or the Servicer’s normal servicing procedures and Accepted
      Servicing Practices) 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(v).

      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 a Servicer and remitted to the Master Servicer)
      in respect of such policies or bonds shall be promptly deposited in the
      Collection Account upon receipt, except that any amounts realized that are
      to be
      applied to the repair or restoration of the related Mortgaged Property or
      release to the Mortgagor in accordance with the Master Servicer’s or the
      Servicer’s normal servicing procedures need not be so deposited (or
      remitted).

                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 non-coverage under any applicable Primary Mortgage Insurance Policy of any
      loss which, but for the actions of such Master Servicer or 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 related Servicing Agreement, as applicable.
      The Master Servicer shall not, and shall not 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 as required by a applicable law or in accordance
      with
      the provisions of this Agreement and the related Servicing Agreement, as
      applicable.

     

    (b)           The
      Master Servicer agrees to present, or 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.

              Trustee
                To Retain Possession of Certain Insurance Policies and

    The
      Trustee (or the applicable Custodian, as directed by the Trustee), 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 applicable
      Custodian, as directed by the Trustee) 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 to be
      delivered to the Trustee (or the applicable Custodian, as directed by the
      Trustee), 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 from time to
      time.

              Realization
                Upon Defaulted Mortgage Loans.

            

    

     

    The
      Master Servicer shall use its reasonable best efforts to, or to cause each
      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 any 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).

              Compensation
                to the Master Servicer.

            

    

     

    The
      Master Servicer shall (i) be entitled, at its election, either (a) to pay itself
      the Master Servicing Fee, in respect of the Mortgage Loans out of any Mortgagor
      payment on account of interest prior to the deposit of such payment in the
      Collection Account it maintains or (b) to withdraw from the Collection Account
      the Master Servicing Fee to the extent permitted by Section 4.02(iv). The Master
      Servicer shall also be entitled, at its election, either (a) to pay itself
      the
      Master Servicing Fee in respect of each delinquent Mortgage Loan master serviced
      by it out of Liquidation Proceeds in respect of such Mortgage Loan or other
      recoveries with respect thereto to the extent permitted in Section 4.02 or
      (b)
      to withdraw from the Collection Account it maintains the Master Servicing Fee
      in
      respect of each Liquidated Mortgage Loan to the extent of such Liquidation
      Proceeds or other recoveries, 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 Penalty
      Amount) 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 therefore 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 additional compensation. The provisions of this Section
      9.21
      are subject to the provisions of Section 6.14(b).

                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, to the extent
      provided in the applicable Servicing Agreement, cause the applicable Servicer
      to
      sell, any REO Property as expeditiously as possible and in accordance with
      the
      provisions of this Agreement and the related 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 applicable 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 any 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 as well as any unpaid Master Servicing Fees or 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
      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 Securities Administrator 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.

    (a)           The
      Master Servicer shall promptly notify the Securities Administrator, 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 and
      (ii) if the Master Servicer shall become (but only to the extent not previously
      disclosed to the Master Servicer and the Depositor) at any time an affiliate
      of
      any of the parties listed on Exhibit R to this Agreement. On or before March
      1st
      of each
      year, the Depositor shall distribute the information in Exhibit R to the Master
      Servicer.

     

    (b)           Not
      later than four Business Days prior to the Distribution Date of each month,
      the
      Master Servicer shall provide to the Securities Administrator, 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. The parties to this Agreement acknowledge
      that
      the performance by the Master Servicer of its duties under this Section 9.23(b)
      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.

      to
      have been certified by a Servicing Officer, setting forth the status of the
      Collection Account maintained by the Master Servicer as of the close of business
      on the related Distribution Date, indicating that all distributions required
      by
      this Agreement to be made by the Master Servicer have been made (or if any
      required distribution has not been made by the Master Servicer, specifying
      the
      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, upon request, any Certificateholders (or by the
      Securities Administrator at the Master Servicer’s expense if the Master Servicer
      shall fail to provide such copies (unless (i) the Master Servicer shall have
      failed to provide the Securities Administrator with such statement or (ii)
      the
      Securities Administrator shall be unaware of the Master Servicer’s failure to
      provide such statement)).

      Servicer shall deliver to the Person designated by the Depositor, in a format
      consistent with other electronic loan level reporting supplied by the Master
      Servicer in connection with similar transactions, “loan level” information with
      respect to the Mortgage Loans as of the related Determination Date, to the
      extent that 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
      Agreement shall be based on information supplied to the Master Servicer by

      shall
      be entitled to rely on such information.

      is in
      the possession of the Master Servicer.

    (a)           Assessment
      of Compliance

     

    (i)           By
      March 15 of each year, commencing in March 2007, the Master Servicer and the
      Securities Administrator, 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 Securities Administrator, 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

      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. Each such assessment, pursuant
      to
      clause (C) above, shall cover, at a minimum, the matters indicated as
      obligations with respect to such Person on Exhibit O attached hereto.

      the Master Servicer and the Securities Administrator (or any Servicing Function
      Participant engaged by it) submit their assessments to the Securities
      Administrator, such parties will also at such time 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 Securities
      Administrator what Relevant Servicing Criteria will be addressed in any such
      reports prepared by any such Servicing Function Participant.

      after receipt of each report on assessment of compliance, the Securities
      Administrator 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 Criteria) for each party as set forth on Exhibit
      O
      and on any similar exhibit set forth in each Servicing Agreement in respect
      of

      shall notify the Depositor of any exceptions.

     

    (iv)           On
      or prior to the Closing Date, the Master Servicer shall deliver to the Sponsor,
      the Securities Administrator and the Depositor a certification in the form

      Reports

     

    (i)           By
      March 15 of each year, commencing in March 2007, the Master Servicer and the
      Securities Administrator, each at its own expense, shall cause, and each such
      party shall cause any Servicing Function Participant engaged by it to cause,
      each at its own expense, a registered public accounting firm (which may also
      render other services to the Master Servicer and the Securities Administrator,
      as the case may be) that is a member of the American Institute of Certified
      Public Accountants to furnish a report to the Sponsor, the Depositor, the Master
      Servicer and the Securities Administrator, as applicable, to the effect that
      (A)
      it has obtained a representation regarding certain matters from the management
      of such party, which includes an assertion that such party has complied with
      the
      Relevant Servicing Criteria, and (B) on the basis of an examination conducted
      by
      such firm in accordance with standards for attestation engagements issued or
      adopted by the PCAOB, it is expressing an opinion as to whether such party’s
      compliance with the Relevant Servicing Criteria was fairly stated in all
      material respects, or it cannot express an overall opinion regarding such
      party’s assessment of compliance with the Relevant Servicing Criteria. In the
      event that an overall opinion cannot be expressed, such registered public
      accounting firm shall state in such report why it was unable to express such
      an
      opinion. Such report must be available for general use and not contain
      restricted use language.

     

    (ii)           Promptly

    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 FNMA or FHLMC and shall have a net worth
      of not less than $15,000,000. Notwithstanding the foregoing, as a condition

      furnish to the Depositor in writing and in form and substance reasonably
      satisfactory to the Depositor, all information reasonably necessary for the
      Securities Administrator to accurately and timely report, pursuant to Section

              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 or the Securities Administrator 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 Securities
      Administrator. In the event such determination of ineligibility of the Master
      Servicer to continue in the capacity of master servicer is made by the Master
      Servicer, the Securities Administrator or the Trustee, no such resignation
      shall
      become effective until a period of time not to exceed ninety days after the
      Securities Administrator receives written notice thereof from the Master
      Servicer or Trustee and until the Securities Administrator shall have assumed,
      or a successor master servicer shall have been appointed by the Trustee or
      the
      Securities Administrator, as applicable, 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 to the Depositor.

              Assignment
                or Delegation of Duties by the Master Servicer.

            

    

     

    (a)           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, the Securities
      Administrator, the Depositor or the Rating Agencies 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, the Securities Administrator 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.

     

    (b)           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, the Securities Administrator 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 and an assessment report as provided in Section
      9.26, which reports the Master Servicer shall include in its attestation and
      assessment reports.

              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)           Neither
      the Master Servicer nor any of the directors, officers, employees or agents
      of
      the Master Servicer 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
      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 and any director, officer, employee or agent
      of
      the Master Servicer 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 and any director, officer, employee or
      agent of the Master Servicer 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.
      Notwithstanding anything herein to the contrary, neither the Master Servicer
      nor
      the Trustee shall have any liability for the servicing of the Additional
      Collateral, including, without limitation, the perfection, continuation, partial
      release, release, termination, realization upon, substitution, foreclosure,
      sale, or any other matter with respect to the Additional Collateral, or the
      enforcement of the Additional Collateral Servicing Agreement.

      and
      the Securities Administrator, and their respective officers, directors, agents
      and affiliates, 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 Trustee or the Securities Administrator may sustain as a result
      of (a) any 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, (b) any 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
      Trustee and the Securities Administrator 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, the Trustee or the
      Securities Administrator 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.

      in
      accordance with the REMIC Provisions with respect to each of REMIC I-1, REMIC
      I-2, REMIC I-3, REMIC II-1 and REMIC II-2. The Trustee shall make such elections
      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. For purposes of such elections, (i) each of the REMIC
      I-1 Interests, other than the Class LTI1-R Interest, is hereby designated as
      a
      regular interest in REMIC I-1; (ii) each of the REMIC I-2 Interests, other
      than
      the Class LTI2-R Interest, is hereby designated as a regular interest in REMIC
      I-2; (iii) each of the REMIC I-3 Interests, other than the Class LTI3-R
      Interest, is hereby designated as a regular interest in REMIC I-3; (iv) each
      of
      the REMIC II-1 Interests, other than the Class LTII1-R Interest, is hereby
      designated as a regular interest in REMIC II-1; and
      (v)
      each of the REMIC II-2 Interests, other than the Class LTII2-R Interest, is
      hereby designated as a regular interest in REMIC II-2.
      The
      Class LTI1-R Interest is hereby designated as the sole residual interest in
      REMIC I-1. The Class LTI2-R Interest is hereby designated as the sole residual
      interest in REMIC I-2. The Class LTI3-R Interest is hereby designated as the
      sole residual interest in REMIC I-3.
      The
      Class LTII1-R Interest is hereby designated as the sole residual interest in
      REMIC II-1. The Class LTII2-R Interest is hereby designated as the sole residual
      interest in REMIC II-2. The Class R Certificate evidences ownership of the
      Class
      LTI1-R Interest, the Class the Class LTI2-R Interest, the Class LTI3-R Interest,
      the Class LTII1-R Interest and the Class LTII2-R Interest. The Class P-I and
      Class P-II 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

      1,
      Pool 2 and Pool 3, and (ii) related to the Mortgage Loans in Pool 4
      each

      execution and delivery hereof, acknowledges the assignment to it of the Grantor
      Trust Assets 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-I
      (in the case of collections of Prepayment Penalty Amounts related to Pool 1,
      Pool 2 and Pool 3) and Class P-II (in the case of collections of Prepayment
      Penalty Amounts related to Pool 4) Certificates. The rights of Holders of the

    (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 Section 1.860G-1(a)(4) is the “Latest Possible
      Maturity Date”.

     

    (c)           The
      Securities Administrator shall pay any and all tax related expenses (not
      including taxes) of each REMIC and each 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 such 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 Securities
      Administrator in fulfilling its duties hereunder (including its duties as tax
      return preparer). The Securities Administrator shall be entitled to
      reimbursement from the Certificate Account of the expenses to the extent (x)
      provided in clause (i) above and (y) in the case of expenses relating to a
      REMIC
      provided for hereunder, such expenses are “unanticipated expenses” within the
      meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii).

     

    (d)           The
      Securities Administrator shall prepare and file, and the Trustee shall sign,
      all
      of each REMIC’s federal and state tax and information returns as such REMIC’s
      direct representative. The Securities Administrator shall prepare and file,
      and
      the Trustee shall sign, all of the tax returns in respect of each Grantor Trust.
      The Securities Administrator shall comply with such requirement by filing Form
      1041. The expenses of preparing and filing such returns shall be borne by the
      Securities Administrator. If any Disqualified Organization acquires any
      Ownership Interest in a Residual Certificate, then the Securities Administrator
      will upon request provide to the Internal Revenue Service, and to the persons
      specified in Sections 860E(e)(3) and (6) of the Code, such information as
      required in Section 860D(a)(6)(B) of the Code needed to compute the tax imposed
      under Section 860E(e) of the Code on transfers of residual interests to
      disqualified organizations and the Securities Administrator will be reimbursed
      by the Trust for all expenses incurred therewith solely from amounts received
      for the provision of such information from persons specified in Sections
      860E(e)(3) and (6) of the Code.

     

    (e)           The
      Securities Administrator or its designee shall perform on behalf of each REMIC
      and each Grantor Trust all reporting and other tax compliance duties that are
      the responsibility of 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 Securities
      Administrator 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
      and (ii) to the Certificateholders such information or reports as are required
      by the Code or REMIC Provisions.

    (f)           The
      Trustee, the Securities Administrator, the Master Servicer and the Holders
      of
      Certificates shall take any action or cause any REMIC hereunder to take any
      action necessary to create or maintain the status of such 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 Securities Administrator, the
      Master Servicer nor the Holder of any Residual Certificate shall take any
      action, cause any REMIC to take any action or fail to take (or fail to cause
      to
      be taken) any action that, under the REMIC Provisions, if taken or not taken,
      as
      the case may be, could (i) endanger the status of any such REMIC as a REMIC
      or
      (ii) result in the imposition of a tax upon any such REMIC (including but not
      limited to the tax on prohibited transactions as defined in Code Section
      860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d)
      of the Code) (either such event, an “Adverse REMIC Event”) unless the Trustee,
      the Securities Administrator 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 endanger such status or result in the
      imposition of such a tax. In addition, prior to taking any action with respect
      to any such REMIC or the assets therein, or causing any such 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 Securities
      Administrator and 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 such REMIC, and no such Person shall take any such
      action or cause such REMIC to take any such action as to which the Trustee,
      the
      Securities Administrator or the Master Servicer has advised it in writing that
      an Adverse REMIC Event could occur.

     

    (g)           The
      Securities Administrator shall prepare or cause to be prepared on behalf of
      the
      Trust Fund, based upon information calculated in accordance with this Agreement
      pursuant to instructions given by the Depositor, the Trustee shall sign and
      the
      Securities Administrator shall file, federal tax returns and appropriate state
      income tax returns and such other returns as may be required by applicable
      law
      relating to the Trust Fund, and shall file any other documents to the extent
      required by applicable state tax law (to the extent such documents are in the
      Securities Administrator’s possession). The Securities Administrator 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 Securities
      Administrator as the Depositor may reasonably request in writing, and shall
      forward to the Trustee for distribution to each Certificateholder such forms
      and
      furnish such information within the control of the Securities Administrator
      as
      are required by the Code and the REMIC Provisions to be furnished to them,
      and
      will prepare and furnish to the Trustee for distribution to Certificateholders
      Form 1099 (supplemental tax information) (or otherwise furnish information
      within the control of the Securities Administrator) to the extent required
      by
      applicable law. The Master Servicer will indemnify the Securities Administrator
      and the Trustee for any liability of or assessment against the Securities
      Administrator or the Trustee, as applicable, resulting from any error in any
      of
      such tax or information returns directly resulting from errors in the
      information provided by such Master Servicer.

     

    (h)           The
      Securities Administrator shall prepare and file with the Internal Revenue
      Service (“IRS”), on behalf of each REMIC, an application on IRS Form SS-4. The
      Securities Administrator, 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 Trustee, the Master Servicer and the Depositor. The
      Securities Administrator will file an IRS Form 8811 for the REMICs created
      hereunder. The Trustee shall sign such forms referred to in this Section
      10.01(h) as may be required under applicable law.

    (i)           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 Trust taxes are not paid by a Residual Certificateholder, the
      Securities Administrator shall pay any remaining REMIC taxes out of current
      or
      future amounts otherwise distributable to the Holder of the Residual Certificate
      in 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 such REMIC, as the case may be.

     

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

     

    (k)           No
      additional contributions of assets shall be made to any REMIC, except as
      expressly provided in this Agreement with respect to Qualified Substitute
      Mortgage Loans and any contributions from the Funding Account as provided for
      in
      Section 5.06 hereof.

     

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

     

    (m)           Upon
      the request of any Rating Agency, the Securities Administrator shall deliver
      to
      such Rating Agency an Officer’s Certificate stating the Securities
      Administrator’s compliance with the provisions of this Section
      10.01.

     

    (n)           The
      Trustee shall provide the Securities Administrator such information as the
      Securities Administrator may reasonably request in connection with its
      responsibilities under this Section 10.01.

    Neither
      the Depositor, the Master Servicer nor the Trustee shall sell, dispose of,
      or
      substitute for any of the Mortgage Loans, except in a disposition pursuant
      to
      (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund,
      (iii) the termination of the REMIC holding such Mortgage Loan pursuant to
      Article VII of this Agreement, (iv) a substitution pursuant to Article II of
      this Agreement, or (v) a repurchase of Mortgage Loans pursuant to Article II
      of
      this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of
      any
      investments in the Certificate Account for gain, nor accept any contributions
      to
      any REMIC after the Closing Date (other than any contributions from the Funding
      Account as provided in Section 5.06 hereof), unless it has received an Opinion
      of Counsel (at the expense of the party causing such sale, disposition, or
      substitution) that such disposition, acquisition, substitution, or acceptance
      will not (a) affect adversely the status of such REMIC as a REMIC or of the
      Certificates other than the Residual Certificates as the regular interests
      therein, (b) affect the distribution of interest or principal on the
      Certificates, (c) result in the encumbrance of the assets transferred or
      assigned to the Trust Fund (except pursuant to the provisions of this Agreement)
      or (d) cause such REMIC to be subject to a tax on prohibited transactions or
      prohibited contributions pursuant to the REMIC Provisions.

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

            

    

     

    In
      the
      event that a REMIC fails to qualify as a REMIC, loses its status as a REMIC,
      or
      incurs federal, state or local taxes as a result of a prohibited transaction
      or
      prohibited contribution under the REMIC Provisions due to the negligent
      performance by the Trustee or the Securities Administrator, as applicable,
      of
      its duties and obligations set forth herein, the Trustee or the Securities
      Administrator, as applicable, shall indemnify the Holder of the Residual
      Certificate against any and all losses, claims, damages, liabilities or expenses
      (“Losses”) resulting from such negligence; provided, however, that neither the
      Trustee nor the Securities Administrator shall be liable for any such Losses
      attributable to the action or inaction of the Master Servicer, the Depositor,
      or
      the Holder of such Residual Certificate, as applicable, nor for any such Losses
      resulting from misinformation provided by the Holder of such Residual
      Certificate on which the Trustee or the Securities Administrator, as applicable,
      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 or the Securities Administrator 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, (2) for any Losses other than arising out of a negligent performance
      by the Trustee or the Securities Administrator, respectively, 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); provided,
      however, that
      this
      sentence shall not apply in connection with any failure by the Trustee to comply
      with the provisions of Section 6.01(l) hereof, or any failure by the Securities
      Administrator to comply with the provisions of Sections 6.01 (k) and (l) and
      Sections 9.25 (a) and (b) hereof.

              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), permit any Servicer to, rent, lease, or
      otherwise earn income or otherwise take or fail to take any action on behalf
      of
      any REMIC with respect to any REO Property which might cause such REO Property
      to fail to qualify as “foreclosure” property within the meaning of section
      860G(a)(8) of the Code or result in the receipt by any REMIC of any “income from
      non-permitted assets” within the meaning of section 860F(a)(2) of the Code or
      any “net income from foreclosure property” which is subject to tax under the
      REMIC Provisions unless the Master Servicer has advised, or has caused the
      applicable Servicer to advise, the Trustee and the Securities Administrator
      in
      writing to the effect that, under the REMIC Provisions, such action would not
      adversely affect the status of any REMIC as a REMIC and any income generated
      for
      such REMIC by the REO Property would not result in the imposition of a tax
      upon
      such REMIC.

     

    (b)           The
      Master Servicer shall make, or shall cause the applicable Servicer 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 from the end of
      the
      calendar year 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 and any relevant proposed legislation
      and under applicable state law, the applicable REMIC may hold REO Property
      for a
      longer period without adversely affecting the REMIC status of such REMIC or
      causing the imposition of a Federal or state tax upon such REMIC. If such an
      extension has been received, then (a) the Master Servicer shall provide a copy
      of such extension to the Trustee and Securities Administrator and (b) the Master
      Servicer, acting on behalf of the Trustee and Securities Administrator
      hereunder, shall, or shall cause the applicable 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, or the Master Servicer is acting
      on
      behalf of the Trustee and Securities Administrator hereunder, or the applicable
      Servicer is unable to sell the REO Property within 33 months after its
      acquisition by the Trust Fund or if the Trustee has received such an extension,
      and the Trustee, or the Master Servicer acting on behalf of the Trustee
      hereunder, is unable to sell the REO Property within the period ending three
      months before the close of the Extended Period, the Master Servicer shall,
      or
      shall cause the applicable Servicer to, before the end of the three year period
      or the Extended Period, as applicable, (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 the Master 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.

      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

              Amendment.

            

    

     

    (a)           This
      Agreement may be amended from time to time by the Depositor, the Master
      Servicer, the Securities Administrator and the Trustee, 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 as evidenced
      by an Opinion of Counsel. 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 may require an Opinion of Counsel (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 receives
      written confirmation from each Rating Agency that such amendment will not cause
      such Rating Agency to reduce, qualify or withdraw 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 Securities Administrator and the Trustee with the consent of
      the
      Holders of not less than 66 2/3% of the Class Principal Amount (or Percentage
      Interest) of each Class of 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, 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) 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 Securities Administrator on
      behalf of the Trustee shall furnish written notification of the substance of
      such amendment to each Holder, 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 such consent shall approve the substance thereof. The manner
      of
      obtaining such consents and of evidencing the authorization of the execution
      thereof by Holders shall be subject to such reasonable regulations as the
      Trustee may prescribe.

     

    (e)           Notwithstanding
      anything to the contrary in any Servicing Agreement, the Trustee shall not
      consent to any amendment of any Servicing Agreement unless (i) such amendment
      is
      effected pursuant to the standards provided in this Section with respect to
      amendment of this Agreement and (ii) except for a Permitted Servicing Amendment,
      any such amendment pursuant to Section 11.03(a)(iii) shall not be materially
      inconsistent with the provisions of such Servicing Agreement.

      anything to the contrary in this Section 11.03, this Agreement may be amended
      from time to time by the Depositor, the Master Servicer, the Securities
      Administrator and the Trustee to the extent necessary, in the judgment of the
      Depositor and its counsel, to comply with the Securities Exchange Act of 1934,
      Regulation AB and any related rules and regulations.

      of aggregate outstanding Certificate Principal Amount (or Notional Amount),
      Certificates owned by the Depositor, the Securities Administrator, the Master
      Servicer, the Trustee or any Servicer or Affiliates thereof are not to be

      so long as any of the Certificates of any Series or Class are “restricted
      securities” within the meaning of Rule 144(a)(3) under the Act, each of the
      Depositor, the Master Servicer, the Securities Administrator and the Trustee
      agree to cooperate with each other to provide to any Certificateholders and
      to
      any prospective purchaser of Certificates designated by such Certificateholder,
      upon the request of such Certificateholder or prospective purchaser, any
      information required to be provided to such holder or prospective purchaser
      to
      satisfy the condition set forth in Rule 144A(d)(4) under the Act. Any
      reasonable, out-of-pocket expenses incurred by the Trustee or the Securities
      Administrator in providing such information shall be reimbursed by the

              Transfer
                of Servicing.

            

    

     

    The
      Seller agrees that it shall provide written notice to the Trustee, the
      Securities Administrator and the Master Servicer thirty days prior to any
      transfer or assignment by the Seller of its rights under any Servicing Agreement
      or of the servicing thereunder or delegation of its rights or duties thereunder
      or any portion thereof to any Person other than the initial Servicer under
      such
      Servicing Agreement; provided
      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 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)          Such
      successor servicer must be qualified to service loans for FNMA or
      FHLMC;

     

    (iii)         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;

     

    (iv)         Such
      successor servicer must execute and deliver to the Trustee, the Securities
      Administrator and the Master Servicer an agreement, in form and substance
      reasonably satisfactory to the Trustee, the Securities Administrator 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 applicable Servicing
      Agreement or, 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;

     

    (v)          If
      the successor servicer is not a Servicer of Mortgage Loans at the time of such
      transfer, there must be delivered to the Trustee and the Securities
      Administrator 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;

     

    (vi)         The
      Seller shall, at its cost and expense, take such steps, or cause the terminated
      Servicer to take such steps, as may be necessary or appropriate to effectuate
      and evidence the transfer of the servicing of the Mortgage Loans to such
      successor 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
      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 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 servicer, or, if such transfer occurs after a Remittance Date but
      before the next succeeding Deposit Date, to the Master Servicer, all funds
      held
      by the applicable 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 servicer, continue to forward to such successor 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 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 servicer, continue to cooperate with the successor servicer
      to
      facilitate such transfer in such manner and to such extent as the successor
      servicer may reasonably request.

      extent that the terms of this Agreement conflict with the terms of any Servicing
      Agreement, the related Servicing Agreement shall govern, unless such provisions
      shall adversely affect the Trustee or the Trust Fund or the status of any REMIC
      created hereunder as a REMIC, provided that nothing in this Section 11.15 shall
      be construed to limit the rights or obligations of the Master Servicer under
      Section 9.05 of this Agreement.

      of
      the parties hereto acknowledges and agrees that the purpose of Sections 6.02,
      6.20, 9.25 and 9.26 of this Agreement is to facilitate compliance by the

      AB
      and (c) the parties shall comply, to the extent practicable from a timing and
