    This
      TRUST AGREEMENT, dated as of October 1, 2007 (the “Agreement”), is by and among
      STRUCTURED ASSET SECURITIES CORPORATION, a Delaware corporation, as depositor
      (the “Depositor”), AURORA LOAN SERVICES LLC, as master servicer (the “Master
      Servicer”) and U.S. BANK NATIONAL ASSOCIATION, a national banking association,
      as trustee (the “Trustee”).

     

    PRELIMINARY
      STATEMENT

     

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

     

    As
      provided herein, elections shall be made in accordance with the provisions
      of
      Section 10.01 that the Trust Fund (other than (i) the Basis Risk Reserve Fund,
      (ii) the rights to receive Prepayment Penalty Amounts distributable to the
      Class
      P Certificates and the Class P Reserve Funds, (iii) 1-X Component Account and
      (iv) the Lower Tier Interests) be treated for federal income tax purposes as
      comprising five 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”).
      Each
      Pool 1 Certificate and the Class X Certificate represents ownership of one
      or
      more regular interests in REMIC I-3 for purposes of the REMIC Provisions. In
      addition, each Pool 1 Senior Certificate (other than the Class 1-AX
      Certificates) represents the right to receive payments with respect to Excess
      Interest. The Class R-I Certificate represents ownership of the sole Class
      of
      residual interest in each of REMIC I-1, REMIC I-2 and REMIC I-3 for purposes
      of
      the REMIC Provisions. Each Pool 2 Certificate (other than the Class R-II
      Certificate) represents ownership of regular interests in REMIC II-2 for
      purposes of the REMIC Provisions. The Class R-II Certificate represents
      ownership of the sole Class of residual interest in each of REMIC II-1 and
      REMIC
      II-2.

     

    POOL
      1 REMICS

     

    REMIC
      I-3 shall hold as its assets the classes of REMIC I-2 Regular
      Interests,
      and the REMIC I-2 Regular Interests are hereby designated as regular interests
      in REMIC I-2. 

     

    REMIC
      I-2
      shall hold as its assets the classes of REMIC I-1 Regular Interests, and the
      REMIC I-1 Regular Interests are hereby designated as regular interests in REMIC
      I-1. REMIC I-1 shall hold as its assets the property of the Trust Fund related
      to Pool 1 other than (i) the Basis Risk Reserve Fund, (ii) the rights to receive
      Prepayment Penalty Amounts distributable to the Class P Certificates and the
      Class P Reserve Funds, (iii) the 1-X Component Account and (iv) the Lower Tier

              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-II 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 their respective Corresponding Certificates. Notwithstanding the
      preceding sentence, (i) the first $0.12 of losses with respect to principal
      on
      the Mortgage Loans in Pool 2 shall be allocated to the Class LTII1-2B6 Interest
      and (ii) immediately preceding any payment to the Class R-II Certificate
      pursuant to Section 5.02(j) attributable to principal received with respect
      to
      any Mortgage Loan in Pool 2, a payment shall be treated as made to the Class
      LTII1-2B6 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 Pool 2 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 all of the several classes of uncertificated
      REMIC
      II-1 Regular Interests.

    


    Each
      of
      the Pool 2 Certificates (other than the Class R-II Certificate) 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-II Certificate. The entitlement of the Class
      R-II
      Certificate to payments of principal and interest shall be attributable to
      its
      representation of the Class LTII2-R Interest.

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

     

    All
      calculations of interest on each regular interest in REMIC II-1 will be made
      on

    LIBOR:
      With
      respect to each 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 six-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” (US0006M). 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.

      (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

      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

      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

      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, applicable Custodian and the Master Servicer.

    Realized
      Loss:
      With
      respect to Pool 1, the excess of the outstanding principal balance of a

      each
      Liquidated Mortgage Loan, an amount equal to (i) the unpaid principal balance
      of
      such Mortgage Loan as of the date of liquidation, plus (ii) interest at the
      applicable Net Mortgage Rate from the date as to which interest was last paid

      of principal and interest due on or before such date), and all such payments
      due
      after such date but received prior to such date and intended by the related
      Mortgagors to be applied after such date, together with all of the Depositor’s
      right, title and interest in and to the Collection Account and all amounts

      Properties and any Additional Collateral, and any proceeds of the foregoing,
      to
      have and to hold, in trust; and the Trustee declares that, subject to the review
      provided for in Section 2.02, it (or a Custodian on its behalf) has received

      conditions set forth in this Agreement, and, concurrently with such receipt,
      the
      Certificates have been executed, authenticated and delivered to or upon the
      order of the Depositor, in exchange for the Trust Fund, in the authorized
      denominations evidencing the entire ownership of the Trust Fund.

    Concurrently
      with the execution and delivery of this Agreement, the Depositor does hereby
      assign to the Trustee all of its rights and interest under the Mortgage Loan
      Sale Agreement; including all rights of the Seller under the applicable
      Servicing Agreement and any related Transfer Agreement (other than first payment
      date default or early payment date default rights against the Transferor, as
      described in such Transfer Agreement) to the extent assigned under the Mortgage
      Loan Sale Agreement. The Trustee hereby accepts such assignment, and shall
      be
      entitled to exercise all rights of the Depositor under the Mortgage Loan Sale
      Agreement as if, for such purpose, it were the Depositor. The Trustee is hereby
      directed to acknowledge and deliver the Servicing Agreement (to the extent
      it is
      a party thereto) and perform in accordance therewith. 

    


    It
      is
      agreed and understood by the Depositor and the Trustee (and the Seller has
      so
      represented and recognized in the Mortgage Loan Sale Agreement) that it is
      not
      intended that any Mortgage Loan to be included in the Trust Fund is a “High-Cost
      Mortgage Loan” as defined under any applicable federal law or state or local
      regulation, ordinance or law.

    


    The
      foregoing sale, transfer, assignment, set-over, deposit and conveyance and
      the
      assignment and transfer with respect to Additional Collateral does not and
      is
      not intended to result in creation or assumption by the Trustee of any
      obligation of the Depositor, the Seller, or any other Person in connection
      with
      the Mortgage Loans, the Servicing Agreements or any other agreement or
      instrument relating thereto except as specifically set forth
      herein.

    


    In
      addition, with respect to any Pledged Asset Mortgage Loan, the Depositor does
      hereby transfer, assign, set-over and otherwise convey to the Trustee without
      recourse (except as provided herein) (i) its rights as assignee under any
      security agreements, pledge agreements or guarantees relating to the Additional
      Collateral supporting any Pledged Asset Mortgage Loan, (ii) its security
      interest in and to any Additional Collateral, (iii) its right to receive
      payments in respect of any Pledged Asset Mortgage Loan pursuant to the
      Additional Collateral Servicing Agreement, and (iv) its rights as beneficiary
      under the surety bond in respect of any Pledged Asset Mortgage Loan.
      Notwithstanding anything to the contrary in this Agreement, the Trust Fund
      shall
      not obtain title to or beneficial ownership of any Additional Collateral as
      a
      result of or in lieu of the disposition thereof or otherwise.

    (b) In
      connection with such transfer and assignment, the Depositor does hereby deliver
      to, and deposit with, or cause to be delivered to and deposited with, the
      Trustee, and/or the Custodian acting on the Trustee’s behalf, the following
      documents or instruments with respect to each Mortgage Loan (each a “Mortgage
      File”) so transferred and assigned (other than the Participations):

    


    (i) with
      respect to each Mortgage Loan, the original Mortgage Note endorsed without
      recourse in proper form to the order of the Trustee, or in blank (in each case,
      with all necessary intervening endorsements as applicable);

    


    (ii) the
      original of any guarantee, security agreement or pledge agreement relating
      to
      any Additional Collateral and executed in connection with the Mortgage Note,

    (iii) with
      respect to each Mortgage Loan other than a Cooperative Loan, the original
      recorded Mortgage with evidence of recording indicated thereon and the original
      recorded power of attorney, if the Mortgage was executed pursuant to a power
      of
      attorney, with evidence of recording thereon or, if such Mortgage or power
      of
      attorney has been submitted for recording but has not been returned from the
      applicable public recording office, has been lost or is not otherwise available,

      to
      be a true and complete copy of the original submitted for recording. If, in
      connection with any Mortgage Loan, the Depositor cannot deliver the Mortgage
      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 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, pending delivery of the original thereof, together with an Officer’s

      in the case of a Mortgage that has been lost, a copy thereof (certified as
      provided for under the laws of the appropriate jurisdiction) and a written
      Opinion of Counsel acceptable to the Trustee and the Depositor that an original
      recorded Mortgage 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,

      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)

      public recording office;

      respect to each Non-MERS Mortgage Loan other than a Cooperative Loan, the
      original Assignment of Mortgage, in form and substance acceptable for recording.
      The Mortgage shall be assigned either (A) in blank, without recourse or (B)

      Mortgage Loan Trust Mortgage Pass Through Certificates, Series 2007-10,” without
      recourse for each Mortgage Loan;

    


    (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 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
      guaranty insurance is required;

    (ix) the
      original of any security agreement, chattel mortgage or equivalent instrument
      executed in connection with the Mortgage or as to any security agreement,

      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

    (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, the Rating Agencies and any NIMS Insurer, 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 the applicable 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 the applicable 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.

    


    (f) 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.

    


    (g) The
      issuing entity is hereby named Structured Adjustable Rate Mortgage Loan Trust,
      Series 2007-10.

      and
      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, 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

      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 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 Trustee, the
      Depositor, the Master Servicer and any NIMS Insurer. 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, the Master Servicer and any NIMS
      Insurer 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.

    


    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 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;

    
      
        
        

      

      
        61

        
          

        

      

      
        
        

      

    

    


    (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;

    


    (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. 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 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 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 any of the Depositor,
      any NIMS Insurer, 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; provided, to the extent that
      knowledge of such breach with respect to any Mortgage Loan is known by any
      officer, director, employee or agent of Aurora acting in any capacity other
      than
      as Master Servicer hereunder, the Master Servicer shall not be deemed to have
      knowledge of any such breach until an officer of the Master Servicer has actual
      knowledge thereof. 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 a mortgage loan 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.

    


    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 Lehman Brothers Holdings pursuant to the 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,
      the Purchase Price 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 certification from the Master Servicer that
      it
      is in receipt of such amount, 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. 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 applicable
      Transferor, or Lehman Brothers Holdings, 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 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 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 (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.

    Section
      2.06. Grant
      Clause.

    


    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 to secure repayment
      of an
      obligation in an amount equal to the aggregate Class Principal Amount of the
      Certificates in all of the Depositor’s right, title and interest in, to and
      under, whether now owned or hereafter acquired, the Trust Fund and all proceeds
      of any and all property constituting the Trust Fund to secure payment of the
      Certificates; and (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.

    


    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 Principal Amount 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 Class R-II Certificates shall each be issued as a single
      Certificate and maintained in definitive, fully registered form in a minimum
      denomination equal to $100, and the and Class P Certificates shall each be
      issued as a single Certificate and maintained in definitive, fully registered
      form in a minimum denomination equal to $1000. The Class X and Class C
      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.

    
      
        
        

      

      
        65

        
          

        

      

      
        
        

      

    

    


    (b) The
      Certificates shall be executed by manual or facsimile signature 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 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 direct the Trustee to execute
      the Certificates and deliver such Certificates by the Depositor to the
      Authenticating Agent for authentication and the Authenticating Agent shall
      authenticate and deliver such Certificates as in this Agreement provided and
      not
      otherwise. The Depositor hereby directs the Trustee to execute the Certificates
      on the Closing Date. 

    


    (c) The
      Privately
      Offered Certificates offered and sold in reliance on the exemption from
      registration under Rule 144A under the Act 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
      Trustee,
      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 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
      Privately Offered 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 Trustee, as custodian for DTC and registered in the name of
      a
      nominee of DTC, duly executed and authenticated by the Trustee and 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 Trustee or DTC or its
      nominee, as the case may be, as hereinafter provided.

    


    (d) The
      Privately Offered 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.

    


    Section
      3.02. Registration.

    


    The
      Trustee 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”) and in such capacity shall be afforded the same protections, rights
      and indemnifications afforded to it as Trustee. 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 any 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 “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 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.

    
      
        
        

      

      
        67

        
          

        

      

      
        
        

      

    

    


    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 ERISA-Restricted Certificate or Residual 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 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. 

    
      
        
        

      

      
        68

        
          

        

      

      
        
        

      

    

    


    Except
      in
      the case of a Definitive Certificate, the representations set forth in the
      preceding two 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 Certificate or Residual Certificate (or the acceptance by
      a
      Certificate Owner of the beneficial interest in any Class of ERISA-Restricted
      Certificate or 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.

    


    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, 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 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 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 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 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”).

    
      
        
        

      

      
        69

        
          

        

      

      
        
        

      

    

    


    Prior
      to
      and as a condition of the registration of any transfer, sale or other
      disposition of a Residual Certificate, the proposed transferee shall deliver
      to
      the Trustee an affidavit in substantially the form attached hereto as Exhibit
      D-1 representing and warranting, among other things, that such transferee is
      neither a Disqualified Organization, an agent or nominee acting on behalf of
      a
      Disqualified Organization, nor a Non-permitted Foreign Holder (any such
      transferee, a “Permitted Transferee”), and the proposed transferor shall deliver
      to the Trustee an affidavit in substantially the form attached hereto as Exhibit
      D-2. In addition, the Trustee may (but shall have no obligation to) require,
      prior to and as a condition of any such transfer, the delivery by the proposed
      transferee of an Opinion of Counsel, addressed to the Depositor, the Master
      Servicer, any NIMS Insurer and the Trustee satisfactory in form and substance
      to
      the Depositor, that such proposed transferee or, if the proposed transferee
      is
      an agent or nominee, the proposed beneficial owner, is not a Disqualified
      Organization, agent or nominee thereof, or 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 a
      Responsible Officer of 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).

    
      
        
        

      

      
        70

        
          

        

      

      
        
        

      

    

    


    (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 Privately Offered 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).

    


    (i) Subject
      to clauses (ii) and (iii) of this Section 3.03(h), transfers of a Global
      Security representing any of the Privately Offered 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.

    


    (ii) 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,
      or
      to transfer its interest in such Restricted Global Security to a Person who
      wishes to take delivery thereof in the form of an interest in a Regulation
      S
      Global Security, such holder, provided such holder is not a U.S. person, may,
      subject to the rules and procedures of DTC, exchange or cause the exchange
      of
      such interest for an equivalent beneficial interest in the Regulation S Global
      Security. Upon receipt by the Certificate Registrar, of (I) instructions from
      DTC directing the Certificate Registrar, to be credited a beneficial interest
      in
      a Regulation S Global Security in an amount equal to the beneficial interest
      in
      such Restricted Global Security to be exchanged but not less than the minimum
      denomination applicable to such holder’s Certificates held through a Regulation
      S Global Security, (II) a written order given in accordance with DTC’s
      procedures containing information regarding the participant account of DTC
      and,
      in the case of a transfer pursuant to and in accordance with Regulation S,
      the
      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
      beneficial interest stating that the exchange or transfer of such interest
      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
      specified in such instructions a beneficial interest in the Regulation S Global
      Security equal to the reduction in the principal amount of the Restricted Global
      Security.

    
      
        
        

      

      
        71

        
          

        

      

      
        
        

      

    

    


    (iii) 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 of 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 under the Act 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.

    


    (iv) 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.

    


    (v) Restrictions
      on U.S. Transfers.
      Transfers of interests in the Regulation S Global Security to U.S. persons
      (as
      defined in Regulation S) shall be limited to transfers made pursuant to the
      provisions of Section 3.03(h)(iii).

    


    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.

    
      
        
        

      

      
        72

        
          

        

      

      
        
        

      

    

    


    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 the 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 the Trustee or 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 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.

    


    
      
        
        

      

      
        73

        
          

        

      

      
        
        

      

    

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

    


    (b) Any
      Paying Agent shall be either a bank or trust company or otherwise authorized
      under law to exercise corporate trust powers. Any 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 Sections 6.20
      and
      9.25, and the related assessment of compliance shall cover, at a minimum, the
      matters indicated as obligations with respect to the Paying Agent on Exhibit
      O
      attached hereto, provided that if the Trustee is the Paying Agent, any reporting
      obligations under Regulation AB specific to the Paying Agent shall be undertaken
      by the Trustee in the course of its own reporting and not separately. In
      addition, any Paying Agent 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 R hereto or any of their
      Affiliates.

    


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

    


    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, 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):

    
      
        
        

      

      
        74

        
          

        

      

      
        
        

      

    

    


    (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 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;

    


    (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 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 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.

      4.01. Collection
      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 “Aurora
      Loan Services LLC as Master Servicer, in trust for the benefit of the Holders
      of
      Structured Adjustable Rate Mortgage Loan Trust Mortgage Pass-Through
      Certificates, Series 2007-10.” The Collection Account shall relate solely to the

      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 10 days and transfer
      all funds on deposit in such existing Collection Account into such new
      Collection Account.

      and
      address of the depository institution at which the Collection Account is
      maintained and the account number of such Collection Account. No later than
      1:00

      4.02), not including any amounts which are to be excluded from the Available
      Distribution Amount for such Distribution Date pursuant to clauses (A) through
      (H) of paragraph (i) of the definition thereof (other than any amounts due

      reimbursable to the Trustee or the Custodians pursuant to this Agreement),
      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,
      may
      choose to make daily remittances from the Collection Account to the Trustee
      for
      deposit into the Certificate Account.

    


    (d) The
      Master Servicer shall deposit or cause to be deposited into the Collection
      Account, no later than the second Business Day following the Closing Date,
      any

      Collection Account on the earlier of the applicable Remittance Date and two
      Business Days following receipt thereof, the following amounts received or
      payments made by it (other than in respect of principal of and interest on
      the

    (i) all
      payments on account of principal, including Principal Prepayments and late
      collections, on the Mortgage Loans;

    


    (ii) all
      payments on account of interest on the Mortgage Loans (other than payments
      due
      prior to the Cut-off Date), net of the applicable Servicing Fee and Master
      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;

    
      
        
        

      

      
        76

        
          

        

      

      
        
        

      

    

    


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

    


    (iv) all
      Insurance Proceeds;

    


    (v) all
      Advances made by the Master Servicer or the applicable Servicer pursuant to
      Section 5.04 or the applicable Servicing Agreement;

    


    (vi) all
      Prepayment Penalty Amounts; 

    


    (vii) all
      proceeds of any Mortgage Loan purchased by any Person; and 

    


    (viii) the
      Purchase Price or Repurchase Price of any Mortgage Loan repurchased by the
      Depositor, the Seller, the Master Servicer or any other Person, and any
      Substitution Amount related 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 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 in trust
      for the benefit of the Trustee and Holders of Structured Adjustable Rate
      Mortgage Loan Trust, Mortgage Pass-Through Certificates, Series 2007-10. 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.

    Section
      4.02. Application
      of Funds in the Collection Account.

    


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

    


    (i) to
      reimburse itself or any Servicer for Advances 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

      Servicing Fees or “unanticipated expenses” within the meaning of Treasury
      Regulation Section 1.860G-1(b)(3)(ii).

    In

      (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), (ii),

      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).

    


    (c) 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 cause the Master Servicer, the
      Custodian and the Servicer to provide the NIMS Insurer with access to the
      Mortgage Files upon reasonable notice and during normal business
      hours.

      data
      regarding the Mortgage Loans and the related REO Property that has been provided

      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,
      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 the NIM Securities or an investment
      in the Certificates; provided, however, that the Master Servicer shall be
      entitled to be reimbursed by such Certificateholder for such Master Servicer’s
      actual expenses incurred in providing such reports and access.

      in accordance with applicable regulations, a report summarizing the items
      provided to Certificateholders pursuant to Section 4.03(a) on an annual basis
      as

      where relevant reports or summaries are required elsewhere in this Agreement.
      Such information shall include the amount of original issue discount accrued
      on
      each Class of Certificates and information regarding the expenses of the Trust
      Fund. The Trustee shall be deemed to have satisfied this requirement if it
      forwards such information in any other format permitted by the Code. The Master
      Servicer, to the extent available to the Master Servicer pursuant to this
      Agreement and each Servicing Agreement, shall provide the Trustee with such
      Mortgage Loan level information as is necessary for the Trustee to prepare
      such

      of
      Taxpayer Identification Number Assigned, shall upon request promptly forward
      a
      copy of such notice to the Master Servicer and the Depositor. The Trustee shall

      Treasury Regulation Section 1.860G-1(b)(3)(ii));

      make
      distributions to the Certificateholders pursuant to Article V; and

    (c) 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 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

    DISTRIBUTIONS
      TO HOLDERS OF CERTIFICATES

    


    Section
      5.01. Distributions
      Generally.

    


    (a) Subject
      to Section 7.01 with respect to the final distribution on the Certificates,
      on
      each Distribution Date the Trustee (or any 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. 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 or Percentage
      Interests).

    


    (c) The
      Trustee (or Paying Agent, as applicable) shall make payments to
      Certificateholders and any other person pursuant to this Article V based solely
      on the information set forth in the monthly report furnished by the Trustee
      in
      accordance with Section 4.03(a), and shall be entitled to conclusively rely
      on
      such information and reports, and on the calculations contained therein, when
      making distributions to Certificateholders and any other party. The Trustee
      (or
      Paying Agent, as applicable) 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.

      Original Credit Support Percentage for such Class, then, notwithstanding
      anything to the contrary in Section 5.02(d), no distribution of amounts

      reduced to zero; and

    


    eighth,
      to the
      Classes of Pool 1 Senior Certificates, pro
      rata,
      in
      accordance with their Class Principal Amounts; provided, however, that
any
      Applied Loss Amount 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.
      

    


    (ii) On
      any
      Distribution Date, the principal portion of each Realized Loss (other than
      any
      Excess Loss) in respect of Pool 2 shall be allocated in the following order
      of
      priority:

    


    first,
      to the
      Class 2-B6 Certificates, until the Class Principal Amount thereof has been

      to the
      related Pool 2 Certificates on the basis of the Certificate Principal Balances;
      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)

    


    (c) Any
      Applied Loss Amounts or 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
      of

      Principal Amount of the related Certificates on the related Distribution Date
      in
      accordance with Section 5.03(d).

    


    (d) Applied
      Loss Amounts or Realized Losses allocated in accordance with this Section 5.03

      in
      which such loss was incurred and, in the case of the principal portion thereof,
      after giving effect to distributions made on such Distribution
      Date.

    


    (e) On
      each
      Distribution Date, amounts described in clauses (i) and (ii) of the definition
      of Subordinate Certificate Writedown Amount for such date shall effect
      corresponding reductions in the Class Principal Amount of the lowest ranking
      Class of outstanding Pool 2 Subordinate Certificates, which reductions shall
      occur on such Distribution Date after giving effect to distributions made on
      such Distribution Date.

    Section
      5.04. Advances
      by the Master Servicer.

    


    (a) Advances
      shall be made in respect of each Deposit Date as provided herein. If, on any
      Determination Date, the Master Servicer determines that any Scheduled Payments
      due during the related Due Period (other than Balloon Payments) have not been
      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 Trustee on such Determination Date, which if 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 Trustee 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 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 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. 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
      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 on Pool
      2
      Mortgage Loans made by the Servicers shall be a component of the Available
      Distribution Amount. Any Compensating Interest Payments on Pool 1 Mortgage
      Loans
      made by the Servicers shall be a component of the Interest Remittance
      Amount.

    Section
      5.07. Basis
      Risk Reserve Funds.

    


    (a) On

      Trust
      Fund, in trust for the benefit of the holders of the Pool 1 Certificates, the
      Basis Risk Reserve Fund. The Basis Risk Reserve Fund shall be an Eligible
      Account, and funds on deposit therein shall be held separate and apart from,
      and
      shall not be commingled with, any other moneys, including, without limitation,
      other moneys of the Trustee held pursuant to this Agreement.

    


    (b) On
      each
      Distribution Date the Trustee shall distribute in the order of priority and
      to
      the extent specified in Section 5.02(e)(iv) of this Agreement the sum of
      (without duplication) any amounts then on deposit in the Basis Risk Reserve
      Fund, including any earnings thereon. On any Distribution Date, any amounts
      that
      the Trustee is not required to distribute from the Basis Risk Reserve Fund
      pursuant to Section 5.02(e)(iv)of this Agreement shall remain on deposit in
      the
      Basis Risk Reserve Fund.

    


    (c) Funds
      in
      the Basis Risk Reserve Fund shall be invested in Eligible Investments. In the
      absence of written instructions from Lehman Brothers Holdings as to investment
      of funds on deposit in the Basis Risk Reserve Fund, such funds shall remain
      uninvested. The Basis Risk Reserve Fund will be terminated after the termination
      of the Trust Fund pursuant to Article VII.

      Omitted. 

    


    Section
      5.12. 1-X
      Component Account.

    


    (a) No
      later
      than the first date on which any NIM Securities are issued, the Trustee shall
      establish and maintain in its name, on behalf of the Trust Fund, for the benefit
      of the holders of the Class X Certificates, the 1-X Component Account and the
      Depositor may deposit a dollar amount into the 1-X Component Account. The 1-X
      Component 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 1-X Component 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 written 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 1-X Component Account that are not invested shall be held in cash. In
      the
      absence of such written direction, all funds in the 1-X Component Account shall
      remain uninvested. Any investment earnings on such amounts shall be payable
      to
      the Class C Certificates. The Trustee shall account for the 1-X Component
      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 1-X Component Account
      for federal tax purposes and the Holders thereof shall direct the Trustee in
      writing as to the investment of amounts therein. Upon termination of the 1-X
      Component Account, any amounts remaining in the 1-X Component 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)(i) hereof. 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).

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

    


    (d) The
      1-X
      Component Account shall terminate on the earlier of (i) the 1-X Component
      Account Termination Date or (ii) the Distribution Date on which the amount
      on
      deposit in the 1-X Component Account is reduced to zero.

    


    Section
      5.13. The
      Class P Reserve Fund.

      National Association, as trustee, in trust for the registered holders of
      Structured Adjustable Rate Mortgage Loan Trust, Mortgage Pass-Through
      Certificates, Series 2007-10” (the “Class 1-AP Reserve Fund”) and “Class 2-AP
      Reserve Fund, U.S. Bank National Association, as trustee, in trust for the
      registered holders of Structured Adjustable Rate Mortgage Loan Trust, Mortgage
      Pass-Through Certificates, Series 2007-10” (the “Class 2-AP Reserve Fund”). The
      Trustee shall credit each of the Class 1-AP Reserve Fund and the Class 2-AP
      Reserve Fund with $1,000 remitted for such purpose to the Trustee by LBH. Funds
      deposited in the Class 1-AP Reserve Fund and the Class 2-AP Reserve Fund shall
      be held in trust by the Trustee on behalf of the Certificateholders until
      distributed pursuant to Section 5.13(c).

    


    (b) Funds
      in
      each of the Class 1-AP Reserve Fund and the Class 2-AP Reserve Fund shall remain
      uninvested.

    


    (c) On

      Distribution Date in September 2012, the Trustee shall distribute $1,000 from
      the Class 1-AP Reserve Fund to the Holders of the Class 1-AP Certificates and

    ARTICLE
      VI

    


    CONCERNING
      THE TRUSTEE; EVENTS OF DEFAULT

    


    Section
      6.01. Duties
      of Trustee.

    


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

    


    (b) The
      Trustee, upon receipt of all resolutions, certificates, statements, opinions,
      reports, documents, orders or other instruments furnished to the Trustee which
      are specifically required to be furnished pursuant to any provision of this
      Agreement, shall examine them to determine whether they are 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 NIMS Insurer or any Servicer to the Trustee pursuant to this
      Agreement, and the Trustee 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. 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 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

    
      
        
        

      

      
        100

        
          

        

      

      
        
        

      

    

    


    (iii) For
      all
      purposes under this Agreement, the Trustee shall not be deemed to have notice
      or
      be required to take notice of any default or 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. In the absence of receipt of such notice
      or
      actual knowledge, the Trustee may conclusively assume that there is no default
      or Event of Default; 

    


    (iv) 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 use its commercially reasonable 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) 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 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.

    


    (g) The
      Trustee shall not be held liable by reason of any insufficiency in any account
      (including without limitation the Collection Account and 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).

    
      
        
        

      

      
        101

        
          

        

      

      
        
        

      

    

    


    (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 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, any Custodian, any Servicer, the NIMS Insurer or the
      Depositor delivered to the Trustee pursuant to this Agreement believed by the
      Trustee to be genuine and to have been signed or presented by the proper party
      or parties.

    


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

    


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

    


    (k) 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.

    


    (l) For
      so
      long as the Depositor is subject to Exchange Act reporting requirements for
      the
Structured
      Adjustable Rate Mortgage Loan Trust Mortgage
      Pass-Through Certificates, Series 2007-10,
      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, and (ii) of any merger, consolidation or sale of substantially
      all of the assets of the Trustee and (iii) if the Trustee shall become (but
      only
      to the extent not previously disclosed) at any time an affiliate of any of
      the
      parties listed on Exhibit R hereto. On or before March 1st of each year, the
      Depositor shall distribute the information on Exhibit R to the Trustee.


    


    Section
      6.02. Certain
      Matters Affecting the Trustee.

    


    Except
      as
      otherwise provided in Section 6.01:

    


    (a) The
      Trustee may request, and may rely upon and shall be protected in acting or
      refraining from acting upon any resolution, Officer’s Certificate, certificate
      of auditors, 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 and to have been signed or presented
      by
      the proper party or parties;

    
      
        
        

      

      
        102

        
          

        

      

      
        
        

      

    

    


    (b) The
      Trustee may consult with counsel and any advice or opinion of its counsel shall
      be full and complete authorization and protection in respect of any action

      such
      advice or opinion of counsel;

    


    (c) 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

      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 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 of the costs, expenses

      payment of such estimated expenses as a condition to proceeding. The reasonable

      by
      the Trust Fund;

    


    (e) 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

      litigation hereunder or in relation hereto, in each case at the request, order
      or direction of any of the Certificateholders pursuant to the provisions of
      this
      Agreement, unless such Certificateholders shall have offered to the Trustee
      security or indemnity satisfactory to the Trustee against the costs, expenses
      and liabilities which may be incurred therein or thereby;

    Section
      6.03. Trustee
      Not Liable for Certificates.

    


    The
      Trustee makes no representations as to the validity or sufficiency of this
      Agreement or any Custodial Agreement, of the Certificates (other than the
      certificate of authentication on the Certificates), or of any Mortgage Loan
      or
      Servicing Agreement, 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, the Custodial Agreements or the Servicing Agreements or
      the
      validity, priority, perfection or sufficiency of the security for the
      Certificates issued or intended to be issued hereunder. Except as otherwise
      provided herein, the Trustee shall not have any 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

    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 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 insured by the FDIC
      and (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 a rating of not less than “A-” by
      S&P, and subject to supervision or examination by federal or state
      authority. 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 either the Trustee shall cease to be eligible in accordance with provisions
      of this Section, the Trustee, as applicable, 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 Trustee, the Depositor, the Rating
      Agencies, any NIMS Insurer and the Master Servicer. Upon receiving such notice
      of resignation, the Depositor will promptly appoint a successor trustee
      acceptable to any NIMS Insurer by written instrument, one copy of which
      instrument shall be delivered to the resigning Trustee, one copy to the
      successor trustee, one copy to each of the Rating Agencies and one copy to
      each
      of the Master Servicer and any NIMS Insurer. If no successor trustee shall
      have
      been so appointed and shall have accepted appointment within 30 days after
      the
      giving of such notice of resignation, the resigning Trustee may petition any
      court of competent jurisdiction for the appointment of a successor
      trustee.

    


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

    


    (c) The
      Holders of more than 50% of the Class Principal Amount (or Class Notional
      Amount) 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 so removed and one copy
      to
      the Master Servicer 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
      acceptance of appointment by the successor trustee as provided in Section
      6.07.

    


    Section
      6.07. Successor
      Trustee.

    


    (a) Any
      successor trustee appointed as provided in Section 6.06 shall execute,
      acknowledge and deliver to the Depositor, the Master Servicer, any NIMS Insurer
      and to its predecessor trustee an instrument accepting such appointment
      hereunder, and thereupon the resignation or removal of the predecessor trustee
      shall become effective and such successor trustee without any further act,
      deed
      or conveyance, shall become fully vested with all the rights, powers, duties
      and
      obligations of its predecessor hereunder, with like effect as if originally
      named as trustee herein. The predecessor trustee shall deliver to the successor
      trustee (or assign to the successor 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 record 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 Master Servicer shall mail notice of the succession of such trustee and
      to
      all Holders of Certificates at their addresses as shown in the Certificate
      Register and to the Rating Agencies. The expenses of such mailing shall be
      borne
      by the party initiating the replacement of the Trustee.

    


    Section
      6.08. Merger
      or Consolidation of Trustee. 

    


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

    


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

    


    (a) Notwithstanding
      any other provisions hereof, at any time, the Trustee, the Depositor or the
      Certificateholders evidencing more than 50% of the Class Principal Amount (or
      Class Notional Amount) of each Class of Certificates shall each 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 hereof shall not be affected or assigned by the appointment of
      a
      co-trustee, provided, however, that prior to the appointment hereunder of any
      such 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
      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.

    
      
        
        

      

      
        106

        
          

        

      

      
        
        

      

    

    


    (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 and a copy given to any NIMS
      Insurer.

    
      
        
        

      

      
        107

        
          

        

      

      
        
        

      

    

    


    (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
      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 under
      such
      Section).

    


    (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, the Trustee and the Depositor and (b) requiring any such
      Subcontractor to provide to the Trustee an assessment of compliance as provided
      in Section 9.25(a) and an attestation report as provided in Section 9.25(b),
      which reports the Trustee shall include in its assessment and attestation
      reports. The Trustee shall indemnify the Depositor, the Master Servicer and
      any
      director, officer, employee or agent of each of the Depositor and the Master
      Servicer and hold them harmless against any and all claims, losses, damages,
      penalties, fines, forfeitures, reasonable and necessary legal fees and related
      costs, judgments, and any other costs, fees and expenses that any of them may
      sustain arising out of or based upon (i) the failure by the Trustee to give
      notice of the engagement of any Subcontractor or (ii) the failure by such
      Subcontractor engaged by the Trustee to provide the Master Servicer and the
      Depositor, either directly or indirectly through 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.

    
      
        
        

      

      
        108

        
          

        

      

      
        
        

      

    

    


    (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
      is
      hereby appointed to act as the initial Authenticating Agent, and the Trustee
      hereby accepts such appointment. Notwithstanding anything to the contrary
      provided herein, 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, such consent shall not
      be
      unreasonably withheld.

    


    (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, provided that such action was
      undertaken without negligence or willful misconduct. 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 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 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:

    
      
        
        

      

      
        109

        
          

        

      

      
        
        

      

    

    


    (a) with
      respect to any such claim, the Trustee shall have given the Depositor, the
      Master Servicer and the Holders written notice thereof promptly after a
      Responsible Officer of 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;

    


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

    


    (c) 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; and

    


    (d) any
      such
      loss, liability or expense identified 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 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 (a) the Trustee 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
      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), 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). 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 (or any
      successor Paying Agent on behalf of 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.

      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 it 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.

      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

    (vi) 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
      such

      does not meet the criteria for a successor servicer as specified in Section
      9.27
      hereof; or

    


    (ix) If
      a

      incorrect as of the time made in any respect that materially and adversely
      affects the interests of the Certificateholders, and the circumstance or

      shall not have been eliminated or cured within 60 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 not less than 25% of the Aggregate Certificate
      Principal Amount of each Class of Certificates or by any NIMS Insurer;
      or

    


    (x) A
      sale or
      pledge of any of the rights of the Master Servicer hereunder or an assignment
      of
      this Agreement by the Master Servicer or a delegation of the rights or duties
      of
      the Master Servicer hereunder shall have occurred in any manner not otherwise
      permitted hereunder, any NIMS Insurer and Certificateholders holding more than
      50% of the Class Principal Amount (or Class Notional Amount) of each Class
      of
      Certificates; or

      not either an FNMA- or FHLMC-approved Seller/Servicer, and the Master Servicer
      has not terminated the rights and obligations of such Servicer under the
      applicable Servicing Agreement and replaced such Servicer with an FNMA- or
      FHLMC-approved servicer within 60 days of the date the Master Servicer receives
      such notice or actual knowledge; or

    


    (xii) After
      any
      receipt of notice from any NIMS Insurer, any failure of the Master Servicer
      to
      remit to the Trustee any payment required to be made to the Trustee for the
      benefit of Certificateholders under the terms of this Agreement, including
      any
      Advance, on any Deposit Date, which such failure continues unremedied after
      1:00
      p.m. Eastern Standard Time one Business Day after the date upon which notice
      of
      such failure shall have been given to the Master Servicer by the
      Trustee.

    
      
        
        

      

      
        112

        
          

        

      

      
        
        

      

    

    


    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 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 (xii) of this
      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 this Section 6.14(a), the Trustee,
      by
      notice in writing to the Master Servicer and the NIMS Insurer, 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 Trustee 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 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 the 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 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 Trustee to correct
      any errors or insufficiencies in the 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; 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.

    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
      has
      actual knowledge, the Trustee shall promptly notify any NIMS Insurer and the
      Rating Agencies of the nature and extent of such Event of Default upon becoming
      aware of the occurrence thereof through the proper execution of its duties
      under
      this Agreement. The Trustee 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 (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 receive 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 Trustee or Master Servicer, as
      applicable, receives written notice pursuant to Section 6.14(a) or Section
      9.28,
      the Trustee, unless another master servicer acceptable to the NIMS Insurer,
      such
      consent shall not be unreasonably withheld, 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 and the compensation described in Section
      9.21. 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 if
      any NIMS Insurer so requests in writing to the Trustee, or shall, if it is
      unable to so act, 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. 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.

    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.

    


    35%
      or
      more 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 (or any successor Paying Agent on behalf
      of
      the Trustee) to make any required payment of principal of or interest on the
      Certificates may only be waived with the consent of 100% of the affected
      Certificateholders and with the consent of any NIMS Insurer. Upon any such
      waiver of a past default, such default shall cease to exist, and any Event
      of
      Default arising therefrom shall be deemed to have been remedied for every
      purpose of this Agreement. No such waiver shall extend to any subsequent or
      other default or impair any right consequent thereon except to the extent
      expressly so waived.

    


    Section
      6.17. Notification
      to Holders.

    


    Upon
      termination of the Master Servicer or appointment of a successor to the Master
      Servicer, in each case as provided herein, the Trustee shall promptly mail
      notice thereof by first class mail to the Certificateholders at their respective
      addresses appearing on the Certificate Register and any NIMS Insurer. The
      Trustee shall also, within 45 days after the occurrence of any Event of Default,
      of which a Responsible Officer of the Trustee has actual knowledge, 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 Class Notional Amount) of each Class of Certificates 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
      security or indemnity reasonably satisfactory to it 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. Notwithstanding
      anything to the contrary provided herein, and 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 a Certificateholder.

    (b) [Reserved].

    


    (c) The

      on
      Form 8-K. Thereafter, the Trustee shall, in accordance with industry standards
      and the rules of the Commission as in effect from time to time (the “Rules”),
      prepare and file with the Commission via the Electronic Data Gathering and
      Retrieval System (“EDGAR”), the reports listed in subsections (d) through (g) of
      this Section 6.20 in respect of the Trust Fund as and to the extent required
      under the Exchange Act.

    


    (d) Reports
      Filed on Form 10-D. 

    


    (i) Within
      15
      days after each Distribution Date (subject to permitted extensions under the
      Exchange Act reporting requirements), 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 P-1 hereto, within five calendar days after the related
      Distribution Date, (A) certain parties to the Structured Adjustable Rate
      Mortgage Loan Trust 2007-10 transaction shall be required to provide to the
      Trustee 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 Trustee 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 Trustee in connection with including
      any Additional Form 10-D Disclosure on Form 10-D pursuant to this
      paragraph.

    
      
        
        

      

      
        117

        
          

        

      

      
        
        

      

    

    


    (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
      duly
      authorized 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 (h)(ii) of this
      Section 6.20. Promptly (but no later than one Business Day) after the deadline
      for filing such report with the Commission, the Trustee will make available
      on
      its internet website a final executed copy of each Form 10-D filed by the
      Trustee. Each party to this Agreement acknowledges that the performance by
      the
      Trustee 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 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.

    


    (e) Reports
      Filed on Form 10-K.

    


    (i) Unless
      and until a Form 15 suspension notice shall have been filed, on or prior to

      90th calendar day after the end of each fiscal year of the Trust Fund or such
      earlier date as may be required by the Exchange Act (the “10-K Filing Deadline”)

      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

      firm attestation report described under Section 9.25(b) hereof or in any
      Servicing Agreement or Custodial Agreement identifies any material instance
      of
      noncompliance, disclosure identifying such instance of noncompliance, or if

      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-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 2008,
      (A) the parties to the Structured Adjustable Rate Mortgage Loan Trust 2007-10
      transaction shall be required to provide to the Trustee 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 Trustee 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 Trustee 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
      Trustee in connection with including any Additional Form 10-K Disclosure on
      Form
      10-K pursuant to this paragraph. 

    


    (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
      of
      business New York City time on the 4th Business Day prior to the 10-K Filing
      Deadline, a senior officer of the Exchange 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 Trustee. If
      a
      Form 10-K cannot be filed on time or if a previously filed Form 10-K needs
      to be
      amended, the Trustee will follow the procedures set forth in subsection (h)(ii)
      of this Section 6.20. Promptly (but no later than one Business Day) after the
      deadline for filing such report with the Commission, the Trustee will make
      available on its internet website a final executed copy of each Form 10-K filed
      by the Trustee. 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 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 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
      10-K shall include the Sarbanes-Oxley Certification. The Trustee, the Paying
      Agent (if other than the Trustee) and, if the Depositor is the Exchange Act
      Signing Party, the Master Servicer, shall, and the Trustee, the Paying Agent
      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-1 or, in the case of (x) the Paying Agent (if other than the Trustee),
      in the form attached hereto as Exhibit Q-2 and (y) the Trustee, the form
      attached hereto as Exhibit Q-2), 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 Paying Agent, the Trustee 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) Each
      of
      Form 10-D and Form 10-K requires the registrant to indicate (by checking “yes”
or “no”) that it “(1) has filed all reports required to be filed by Section 13
      or 15(d) of the Exchange Act during the preceding 12 months (or for such shorter
      period that the registrant was required to file such reports), and (2) has
      been
      subject to such filing requirements for the past 90 days.” The Depositor shall
      notify the Trustee in writing, no later than the fifth calendar day after the
      related Distribution Date with respect to the filing of a report on Form 10-
      D
      and no later than March 15th with respect to the filing of a report on Form
      10-K, whether the Trustee should indicate “[Yes ____] or [No____]” on Form 10-D
      or Form 10-K, as applicable; provided, that if the Trustee does not receive
      such
      written notification from the Depositor, then the Trustee shall be entitled
      to
      affirmatively conclude that the Depositor (1) has filed all reports required
      to
      be filed by Section 13 or 15(d) of the Exchange Act during the preceding 12
      months (or for such shorter period if applicable), and (2) has been subject
      to
      such filing requirements for the past 90 days. The Trustee shall be entitled
      to
      rely on such written notification or an affirmative indication in the absence
      of
      such notification in timely preparing, executing and/or filing any such report
      in accordance with this Section 6.20(f).

      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 paragraph 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.

      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) the parties
      to the Structured Adjustable Rate Mortgage Loan Trust 2007-10 transaction (as
      identified on Exhibit P-3) shall provide to the Trustee and the Depositor,
      to
      the extent known by a Responsible Officer thereof, in EDGAR-compatible form

      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 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 Trustee 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
      Trustee in connection with including any Form 8-K Disclosure Information on
      Form
      8-K pursuant to this paragraph.

      a

      forth in subsection (h)(ii) of this Section 6.20. Promptly (but no later than
      one Business Day) after the deadline for filing such form with the Commission,
      the Trustee will make available on its internet website a final executed copy
      of
      each Form 8-K prepared and filed by it pursuant to this Section 6.20(g). The
      parties to this Agreement acknowledge that the performance by the Trustee of

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


    


    (h) Delisting;
      Amendments; Late Filings.

    


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

    


    (ii) In
      the
      event that the Trustee becomes aware that it will be unable to timely file
      with
      the Commission all or any required portion of any Form 8-K, 10-D or 10-K
      required to be filed by this Agreement because required disclosure information
      was either not delivered to it or delivered to it after the delivery deadlines
      set forth in this Agreement or for any other reason, the Trustee will 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 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 due to a change
      to
      an additional reporting item, the Trustee will notify the Depositor and any
      applicable party 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 duly authorized officer or a senior officer of the
      Exchange Act Signing Party, as applicable. The parties to this Agreement
      acknowledge that the performance by the Trustee of its duties under this Section
      6.20(h) 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.

    (i) 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.
      

    


    (j) 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.

      reasonable requests made by the Sponsor, the Master Servicer, the Trustee or
      the
      Depositor for delivery of additional or different information as the Sponsor,
      the Master Servicer, the Trustee or the Depositor may determine in good faith
      is
      necessary to comply with the provisions of Regulation AB, provided that such
      information is available without unreasonable effort or expense and within
      such
      timeframe as may be reasonably requested.

      by the Trustee 

    


    The
      Trustee (including in its capacity as Paying Agent) agrees to indemnify the

    Section
      7.01. Termination
      of Trust Fund Upon Repurchase or Liquidation of All Mortgage
      Loans.

    


    (a) The
      respective obligations and responsibilities of the Trustee and the Master
      Servicer created hereby (other than the obligation of the Trustee to make
      payments to Certificateholders as set forth in Section 7.02, the obligation
      of
      the Master Servicer to make a final remittance to the Trustee for deposit into
      the Certificate Account 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 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 Pool 1 is less than 10% of the
      Scheduled Principal Balance of the Mortgage Loans in Pool 1 as of the Cut-off
      Date or (y) the aggregate total Scheduled Principal Balance of the Mortgage
      Loans in Pool 2 is less than 10% of the aggregate Scheduled Principal Balance
      of
      the Mortgage Loans in Pool 2 as of the Cut-off Date the Master Servicer, with
      the prior written consent of any NIMS Insurer and the Seller (which consent
      will
      not be 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 or
      (y)
      Pool 2, as applicable, 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 the 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 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
      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 any NIMS Insurer, and (iii) any
      unreimbursed Servicing Advances with respect to each applicable Mortgage Loan
      and; 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 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 Trustee shall distribute the assets of the applicable
      Pool or Pools 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 related 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 sale
      or purchase of the Pool Assets 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. For purposes of the REMIC Provisions, any NIM Redemption
      Amount shall not be treated as having been paid into any REMIC.

    Section
      7.02. Procedure
      Upon Termination of Trust Fund.

    


    (a) Notice
      of
      any termination of the Trust Fund (or the retirement of the Certificates related
      to Mortgage Pool 1 or Mortgage Pool 2, as applicable) pursuant to the provisions
      of Section 7.01, specifying the Distribution Date upon which the final
      distribution shall be made, shall be given promptly by the Trustee by first
      class mail to the applicable Certificateholders, the Trustee and any NIMS
      Insurer mailed (x) no later than five Business Days after the Trustee has
      received notice from the Master Servicer of its intent to exercise its right
      to
      cause the termination of the Trust Fund pursuant to Section 7.01(b) (or the
      retirement of the Certificates related to Mortgage Pool 1 or Mortgage Pool
      2, as
      applicable, to the extent the other such Mortgage Pool is not terminated
      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 Trustee therein specified. The Trustee shall give such
      notice to the Master Servicer, the Custodians, 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, and the Trustee shall terminate 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.

    
      
        
        

      

      
        126

        
          

        

      

      
        
        

      

    

    


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

    


    (c) Any
      reasonable expenses incurred by the Trustee in connection with any termination
      or liquidation of the Trust Fund (or a Mortgage 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).

    


    Section
      7.03. Additional
      Requirements under the REMIC Provisions.

    


    (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, 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 related REMIC) shall terminate at that
      time; 

    


    (ii) in
      the
      case of a sale of the assets of Pool 1:

    


    (A) The
      Trustee shall sell all of the assets of Pool 1 for cash and, within 90 days
      of

      I-3; and

    


    (B) The
      Trustee shall attach a statement to the final Federal income tax return for
      each

      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

    
      
        
        

      

      
        127

        
          

        

      

      
        
        

      

    

    


    (iii) in
      the
      case of a sale of the assets of Pool 2:

    


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

    


    (B) The
      Trustee shall attach a statement to the final Federal income tax return for
      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

      OF
      CERTIFICATEHOLDERS

    


    Section
      8.01. Limitation
      on Rights of Holders.

    


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

    (b) No
      Certificateholder, solely by virtue of its status as Certificateholder, shall
      have any right by virtue or by availing of any provision of this Agreement
      to
      institute any suit, action or proceeding in equity or at law upon or under
      or
      with respect to this Agreement, unless such Holder previously shall have given
      to the Trustee a written notice of an Event of Default and of the continuance
      thereof, as hereinbefore provided, and unless also the Holders of Certificates
      evidencing not less than 25% of the Class Principal Amount (or Class Notional
      Amount or Percentage Interest) of Certificates of each Class affected thereby
      shall have made written request upon the Trustee to institute such action,
      suit
      or proceeding in its own name as Trustee hereunder and shall have offered to
      the
      Trustee such indemnity reasonably satisfactory to it 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
      any
      other party other than the Trustee is acting as Certificate Registrar, then
      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 Trustee, the Master
      Servicer and the Certificate Registrar that neither the Depositor, 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..

    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, 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
      Master Servicer, if made in the manner provided in this Section. Each of the
      Trustee and 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 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 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.

    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 Fidelity Bond and
      an
      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 FNMA or FHLMC 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 a 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 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
      Trustee 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.

    


    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 each
      Rating Agency, any NIMS Insurer, and the Depositor a copy of the annual audited
      financial statements of its corporate parent on or prior to March 31st of each
      year commencing on March 31, 2008.  Such financial statements shall include
      comparative balance sheets, income statements, statement of changes in
      shareholder's equity, statements of cash flows, a consolidating schedule showing
      consolidated subsidiaries and any related notes required pursuant to generally
      accepted accounting principles, certified by a nationally recognized firm of
      Independent Accountants to the effect that such financial statements were
      examined and prepared in accordance with generally accepted accounting
      principles applied on a basis consistent with that of the preceding
      year.

    Section
      9.04. Power
      to Act; Procedures.

    


    (a) The
      Master Servicer shall master service the Mortgage Loans and shall have full
      power and authority, subject to the REMIC Provisions and the provisions of
      Article X hereof, and each Servicer shall have full power and authority (to
      the
      extent provided in the applicable Servicing Agreement) to do any and all things
      that it may deem necessary or desirable in connection with the servicing and
      administration of the Mortgage Loans, including but not limited to the power
      and
      authority (i) to execute and deliver, on behalf of the Certificateholders and
      the Trustee, customary consents or waivers and other instruments and documents,
      (ii) to consent to transfers of any Mortgaged Property and assumptions of the
      Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds
      and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion
      of the ownership of the Mortgaged Property securing any Mortgage Loan, in each
      case, in accordance with the provisions of this Agreement and the applicable
      Servicing Agreement, as applicable; provided that the Master Servicer shall
      not
      take, or knowingly permit any Servicer to take, any action that is inconsistent
      with or prejudices the interests of the Trust Fund or the Certificateholders
      in
      any Mortgage Loan or the rights and interests of the Depositor, the Trustee
      and
      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 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. Notwithstanding anything to the contrary, the
      Master Servicer shall not without 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 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;
      provided, however, that the maturity of any Mortgage Loan shall not be extended
      past the Final Scheduled Distribution 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 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 (i) the collection of the Prepayment
      Penalty Amount would be in violation of applicable laws or (ii) 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) such modification, waiver or amendment would not
      cause an Adverse REMIC Event.

    (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 therefor 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.

    


    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 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).

    


    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 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.

    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 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.

    


    Section
      9.09. No
      Contractual Relationship Between the Servicers, any NIMS Insurer and Trustee
      or
      Depositor.

    


    Any
      Servicing Agreement that may be entered into 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, the Trustee 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.

    


    Section
      9.10. Assumption
      of Servicing Agreement by 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 Trustee receives written notice
      from
      the Trustee pursuant to Section 6.14 or Section 9.28, as applicable, the Trustee
      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 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.

    


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

    


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

    


    Section
      9.12. Release
      of Mortgage Files.

    


    (a) Upon
      (i)
      becoming aware of the payment in full of any Mortgage Loan, (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 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, 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 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
      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.

    


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

    


    (a) The
      Master Servicer shall transmit, or cause the applicable Servicer to transmit,
      to
      the Trustee or the applicable custodian 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 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 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 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.

    
      
        
        

      

      
        138

        
          

        

      

      
        
        

      

    

    


    (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 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.

    


    (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.

    (a) The

      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 certificate of formation or limited liability company
      agreement, (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,

      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

      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

      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;

    
      
        
        

      

      
        140

        
          

        

      

      
        
        

      

    

    


    (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
      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; 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 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 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, Master Servicer, any NIMS
      Insurer 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).

    
      
        
        

      

      
        141

        
          

        

      

      
        
        

      

    

    


    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.

    


    Section
      9.15. Closing
      Certificate and Opinion.

    


    On
      or
      before the Closing Date, the Master Servicer shall cause to be delivered to
      the
      Depositor, the Trustee and Lehman Brothers Inc. an Opinion 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 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.

    


    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
      (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.

    


    Section
      9.17. Presentment
      of Claims and Collection of Proceeds.

    


    The
      Master Servicer shall, or 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 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
      released to the Mortgagor in accordance with the Master Servicer’s or the
      Servicer’s normal servicing procedures need not be so deposited (or
      remitted).

    
      
        
        

      

      
        142

        
          

        

      

      
        
        

      

    

    


    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 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.

    


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

    


    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, on behalf of 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), 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.

    


    Section
      9.20. Realization
      Upon Defaulted Mortgage Loans.

    


    (a)
      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).

    
      
        
        

      

      
        143

        
          

        

      

      
        
        

      

    

    


    (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 (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 Paying
      Agent 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 additional compensation. The provisions of this Section
      9.21
      are subject to the provisions of Section 6.14(b).

    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, 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 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.

    (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 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 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. 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.

    


    (c) In
      the
      event of the appointment of any NIMS Insurer, the Depositor or Seller shall
      promptly notify the Master Servicer and the Trustee of such appointment.

    (a) Not
      later
      than 30 days after each Distribution Date, the Master Servicer shall forward

      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 Trustee 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 Trustee with such statement or (ii)
      the Trustee shall be unaware of the Master Servicer’s failure to provide such
      statement)).

    


    (b) Not
      later
      than two Business Days following each Distribution Date, the Master Servicer
      shall deliver to the Person designated by the Depositor, in a format consistent

      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
      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 provided that such information is in the possession of the Master
      Servicer.

    


    Section
      9.25. Assessment
      of Compliance and Attestation Reports.

    


    (a) Assessment
      of Compliance

    


    (i) On
      or
      before March 15th of each calendar year in which the Depositor is required
      to
      file reports with respect to the Trust Fund in accordance with the Exchange
      Act
      and the rules and regulations of the Commission, beginning with March 15, 2008,
      the Master Servicer, the Paying Agent (if other than the Trustee) and the
      Trustee, each at its own expense, shall furnish, and each such party shall
      cause
      any Servicing Function Participant engaged by it to furnish, each at its own
      expense, to the Sponsor, the Depositor, the Master Servicer and the Trustee,
      a
      report on an assessment of compliance with the Relevant Servicing Criteria
      that
      contains (A) a statement by such party of its responsibility for assessing
      compliance with the Relevant Servicing Criteria, (B) a statement that such
      party
      used the Servicing Criteria to assess compliance with the Relevant Servicing
      Criteria, (C) such party’s assessment of compliance with the Relevant Servicing
      Criteria as of and for the fiscal year covered by the Form 10-K required to
      be
      filed pursuant to Section 6.20(e), including, if there has been any material
      instance of noncompliance with the Relevant Servicing Criteria, a discussion
      of
      each such failure and the nature and status thereof, and (D) a statement that
      a
      registered public accounting firm has issued an attestation report on such
      party’s assessment of compliance with the Relevant Servicing Criteria as of and
      for such period. 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. If the Trustee and the Paying Agent are
      the
      same party, the Relevant Servicing Criteria of the Paying Agent shall be
      included in the Trustee's report. The Master Servicer shall furnish to the
      Trustee copies of the assessments of compliance provided to it by the Custodians
      pursuant to the Custodial Agreements and by each Servicer pursuant to the
      related Servicing Agreement, to the extent that the Trustee is not entitled
      to
      receive such assessments pursuant to each such applicable
      agreement.

    


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

    
      
        
        

      

      
        147

        
          

        

      

      
        
        

      

    

    


    (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 Criteria) for each party as set forth on Exhibit O and on any similar
      exhibit set forth in each Servicing Agreement in respect of each Servicer,
      and
      each Custodial Agreement in respect of each Custodian, and shall notify the
      Depositor of any exceptions. By way of clarification and for the avoidance
      of
      doubt, it is acknowledged that the Trustee shall rely exclusively on Exhibit
      O
      and any similar exhibit set forth in each Servicing Agreement in respect of
      each
      Servicer and each Custodial Agreement in respect of each Custodian, to determine
      such applicable Servicing Criteria and Relevant Servicing Criteria, as the
      case
      may be, and shall not otherwise be reporting on the content of or sufficiency
      of
      such assessments. 

    


    (b) Attestation
      Reports

    


    (i) On
      or
      before March 15th of each calendar year in which the Depositor is required
      to
      file reports with respect to the Trust Fund in accordance with the Exchange
      Act
      and the rules and regulations of the Commission, beginning with March 15, 2008,
      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, Paying Agent or 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, 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. If the Trustee and the Paying Agent are the
      same party, the attestation report caused to be furnished by the Trustee shall
      also address the Relevant Servicing Criteria of the Paying Agent. 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.

    
      
        
        

      

      
        148

        
          

        

      

      
        
        

      

    

    


    (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.

    


    Section
      9.26. Annual
      Statement of Compliance with Applicable Servicing Criteria .

    


    The
      Master Servicer shall deliver (and the Master Servicer shall cause any
      Additional Servicer engaged by it to deliver) to the Sponsor, the Depositor
      and
      the Trustee on or before March 15 of each year, commencing in March 2008, an
      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

      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
      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. 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 or the Trustee, no such resignation shall become effective
      until a period of time not to exceed ninety days after the Trustee receives
      written notice thereof from the Master Servicer, or the date on which the
      Trustee makes such determination, as applicable, 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,
      such consent shall not be unreasonably withheld, 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.

    Section
      9.29. 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 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 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. 

    


    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 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, the Seller 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. 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.

    


    Section
      9.31. Indemnification;
      Third-Party Claims.

    


    The

      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 or the Trustee
      (including in its capacity as the Certificate Registrar and the Paying Agent)
      may sustain arising out of or based upon (a) any material breach by the Master
      Servicer of any of its obligations hereunder, including particularly its
      obligations to provide any report under Section 9.25(a), Section 9.25(b) or
      Section 9.26 or any information, data or materials required to be included
      in
      any Exchange Act report, provided, however, that in no event shall the Master
      Servicer be liable for any special, consequential, indirect or punitive damages

      damages, (b) any material misstatement or omission on any information, data,

      Agreement or the Mortgage Loans entitling the Depositor, the Sponsor or the
      Trustee to indemnification hereunder, whereupon the Master Servicer shall assume

    Section
      10.01. REMIC
      and Grantor Trust Administration.

    


    (a) REMIC
      elections for each REMIC created hereunder 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. For purposes
      of such elections, (i) each of the REMIC I-1 Regular Interests is hereby
      designated as a regular interest in REMIC I-1; (ii) each of the REMIC I-2
      Regular Interests is hereby designated as a regular interest in REMIC I-2;
      (iii)
      each of the REMIC I-3 Regular Interests is hereby designated as a regular
      interest in REMIC I-3; (iv) each of the REMIC II-1 Regular Interests is hereby
      designated as a regular interest in REMIC II-1; and (v) each of the REMIC II-2
      Regular Interests 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
      Residual I 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-I Certificate evidences
      ownership of the Class LTI1-R Interest, the Class LTI2-R Interest and the
      Residual I Interest. The Class R-II Certificate evidences ownership of the
      Class
      LTII1-R Interest and the Class LTII2-R Interest. The Class 1-AP and Class 2-AP
      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 Penalty
      Amounts (i) related to the Mortgage Loans in Pool
      1 and (ii) related to the Mortgage Loans in Pool 2, each
      constitute a grantor trust for federal income tax purposes. The Trustee, by
      its
      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
      1-AP (in the case of collections of Prepayment Penalty Amounts related to Pool
      1) and Class 2-AP (in the case of collections of Prepayment Penalty Amounts
      related to Pool 2) Certificates. The
      rights of Holders of the Class 1-AP and Class 2-AP Certificates to receive
      distributions from the proceeds of the Grantor Trust Assets, and all ownership
      interests of such Holders in and to such distributions, shall be as set forth
      in
      this Agreement.

    The
      Class
      1-AP 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 in Pool 1 distributable to the Class 1-AP
      Certificates and the related Class P Reserve Fund 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 Class P Reserve Fund 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 1-AP Certificates. The rights of Holders of the
      Class 1-AP Certificates to receive distributions from the proceeds of such
      Prepayment Premiums and Class P Reserve Fund, and all ownership interests of
      such Holders in and to such distributions, shall be as set forth in this
      Agreement.

    


    The
      Class
      2-AP 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 in Pool 2 distributable to the Class 2-AP
      Certificates and the related Class P Reserve Fund 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 Class P Reserve Fund 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 2-AP Certificates. The rights of Holders of the
      Class 2-AP Certificates to receive distributions from the proceeds of such
      Prepayment Premiums and Class P Reserve Fund, and all ownership interests of
      such Holders in and to such distributions, shall be as set forth in this
      Agreement.

    


    (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
      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 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 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) 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). Any reimbursement described
      in
      the preceding sentence shall be allocated and limited to collections or other
      recoveries on the related Mortgage Pool and shall be accounted for in such
      manner.

    
      
        
        

      

      
        153

        
          

        

      

      
        
        

      

    

    


    (d) The
      Trustee shall prepare, file and sign, all of each REMIC’s federal and state tax
      and information returns as such REMIC’s direct representative. The Trustee shall
      prepare, file, and sign all of the tax 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. If any
      Disqualified Organization acquires any Ownership Interest in a Residual
      Certificate, then the Trustee 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 Trustee 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
      Trustee 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 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 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 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 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 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 (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 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
      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 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 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 NIMS Insurer or the Master Servicer has advised it
      in
      writing that an Adverse REMIC Event could occur.

    


    (g) 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 further, the Trustee shall sign and
      file, federal tax returns (including but not limited to appropriate REMIC
      elections on Form 1066) 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 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 will indemnify the Trustee for any liability
      of or assessment against 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
      Trustee shall prepare and file with the Internal Revenue Service (“IRS”), on
      behalf of each REMIC, 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 Trustee, the Master
      Servicer and the Depositor. The Trustee 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 Trustee
      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
      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.

    


    (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 Trustee 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 or any NIMS Insurer, the Trustee shall deliver
      to
      such Rating Agency and to the NIMS Insurer an Officer’s Certificate stating the
      Trustee’s compliance with the provisions of this Section 10.01. 

    


    (n) REMIC
      I-1
      shall consist of all of the assets of the Trust Fund related to Pool 1 (other
      than (i) the Basis Risk Reserve Fund, (ii) the rights to receive Prepayment
      Penalty Amounts distributable to the Class P Certificates and the Class P
      Reserve Funds, (iii) the 1-X Component Account, (iv) the Lower Tier Interests
      and (v) any of the grantor trusts described in Section 10.01 hereof). The REMIC
      I-1 Regular Interests shall be designated as the regular interests in REMIC
      I-1,
      and the Class LTI1-R Interest shall be designated as the sole class of residual
      interest in REMIC I-1. Each of the REMIC I-1 Regular Interests shall have the
      characteristics set forth in the Preliminary Statement.

    
      
        
        

      

      
        155

        
          

        

      

      
        
        

      

    

    


    The
      assets of REMIC I-2 shall be the REMIC I-1 Regular Interests. The REMIC I-2
      Regular Interests shall be designated as the regular interests in REMIC I-2,
      and
      the Class LTI2-R Interest shall be designated as the sole class of residual
      interest in REMIC I-2. Each of the REMIC I-2 Regular Interests shall have the
      characteristics set forth in the Preliminary Statement.

    


    The
      assets of REMIC I-3 shall be the REMIC I-2 Regular Interests. The REMIC I-3
      Regular Interests shall be designated as the regular interests in REMIC I-3
      and
      the Residual I Interest shall be designated as the sole class of residual
      interest in REMIC I-3.

    


    The
      beneficial ownership of the Class LTI1-R Interest, the Class LTI2-R Interest
      and
      the Residual I Interest shall be represented by the Class R-I Certificate.
      None
      of the Class LTI1-R Interest, the Class LTI2-R Interest and the Residual I
      Interest shall have a principal balance or bear interest.

    


    REMIC
      II-1 shall consist of all of the assets of the Trust Fund related to Pool 2
      (other than the rights to receive Prepayment Penalty Amounts distributable
      to
      the Class 2-AP Certificates and the Class P Reserve Funds). The REMIC II-1
      Regular Interests shall be designated as the regular interests in REMIC II-1,
      and the Class LTII1-R Interest shall be designated as the sole class of residual

    The
      beneficial ownership of the Class LTII1-R Interest and Class LTII2-R Interest
      shall be represented by the Class R-II Certificate. The entitlement of the
      Class
      R-II Certificate to payments of principal and interest shall be attributable
      to
      its representation of the Class LTII2-R Interest.

    


    (o) It
      is
      intended that the rights of each Class of Pool 1 Senior P&I 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 Pool 1 Senior P&I Certificates
      and such shall be accounted for as property held separate and apart from the
      regular interests in REMIC I-3 held by the holders of the Pool 1 Senior P&I
      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 Pool 1 Senior P&I Certificates receive payments in respect of
      Excess Interest, such amounts, to the extent not derived from payments in
      respect of Class I Shortfalls, will be treated as distributed by REMIC I-3
      to
      the Class X Certificates in
      respect of the Uncertificated Class 1-X Interest pro
      rata
      and then
      paid to the relevant Class of Pool 1 Senior P&I Certificates pursuant to the
      related interest rate cap agreement. The Trustee is hereby directed to perform
      its duties and obligations in accordance with this Section
      10.01(o).

    
      
        
        

      

      
        156

        
          

        

      

      
        
        

      

    

    


    (p) The
      parties hereto intend that the Uncertificated Class 1-X Interest, the Basis
      Risk
      Reserve Fund and the obligation of the holders of the Class X Certificates
      to
      pay amounts of Excess Interest to the holders of the Pool 1 Senior P&I
      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 Pool 1 Certificates and Class
      X 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(p).

    


    (q) [Reserved.]

    


    (r) 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.

    


    (s) The
      Trustee shall treat the 1-X Component 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. 

    


    (t) REMIC
      I-1:
      On each
      Distribution Date, the Trustee shall first pay or charge as an expense of REMIC
      I-1 all expenses of the Trust Fund related to Pool 1 for such Distribution
      Date.

    


    All
      payments received by REMIC I-1 with respect to the Mortgage Loans in Pool 1
      (net
      of expenses described in the preceding paragraph) shall be paid to the REMIC
      I-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 LTI1-R
      Interest.

    


    On
      each
      Distribution Date,

    


    (i) interest
      shortfalls with respect to the Mortgage Loans in Pool 1 shall be allocated
      to
      the REMIC I-1 Regular Interests pro
      rata
      based on
      interest otherwise accrued thereon;

    


    (ii) the
      principal balance of each REMIC I-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 I-1 with respect to the Mortgage Loans in Pool 1 shall be
      distributed to, and losses with respect to the Mortgage Loans in Pool 1 shall
      be
      allocated, first, to each of the REMIC I-1 Marker Classes, in reduction of
      its
      principal balance so that its principal balance is a close as possible to 50%
      of
      the principal balance of its Corresponding Class, and second, to
      the
      Class LTI1-X Interest in reduction of its principal balance so that its
      principal balance is as close as possible to the sum of (x) 50% of the aggregate
      Scheduled Principal Balance of the Mortgage Loans in Pool 1 and (y) 50% of
      the
      Overcollateralization Amount with respect to Pool 1.

    
      
        
        

      

      
        157

        
          

        

      

      
        
        

      

    

    


    If
      on any
      Distribution Date there is an increase in the Certificate Principal Amount
      of
      any Pool 1 Certificate 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 REMIC I-1 Regular Interests allocated as
      follows:

    


    first,
      to each
      of the REMIC I-1 Regular Interests (other than the Class LTI1-X Interest) so
      that the principal balance of each such interest is as close as possible to
      50%
      of the principal balances of its Corresponding Class; and

    


    second,
      to the
      Class LTI1-X Interest so that the principal balance of such interest is as
      close
      as possible to the sum of (x) 50% of the aggregate Scheduled Principal Balance
      of the Mortgage Loans in Pool 1 and (y) 50% of the Overcollateralization Amount
      with
      respect to Pool 1.

    


    REMIC
      I-2:
      All payments received by REMIC I-2 with respect to the REMIC I-1 Regular
      Interests shall be paid to the REMIC I-2 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 LTI2-R
      Interest.

    


    The
      REMIC
      I-2 Regular Interests (other than the Class LTI2-X Interest) shall be entitled
      to all payments and allocations made with respect to their respective Related
      Certificates (disregarding any payments in respect of Excess Interest);
      provided, however, that for this purpose the Class 1-AX Certificates shall
      be
      treated as a Related Certificate of (i) the Class LTI2-1A1 Interest to the
      extent of the portion of its Class Notional Amount that is attributable to
      the
      Class Principal Amount of the Class 1-A1 Certificates and (ii) the Class
      LTI2-1A2 Interest to the extent of the portion of its Class Notional Amount
      that
      is attributable to the Class Principal Amount of the Class 1-A2 Certificates.
      The Class LTI2-X Interest shall be entitled to all payments and allocations
      made
      with respect to the Uncertificated Class 1-X Interest.

    


    (u) 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
      Pool
      1 Certificates in amounts that differ from those payable pursuant to the regular
      interest or interests in REMIC I-3 corresponding to such Class as amounts paid
      or received (as appropriate) pursuant to any 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.

    


    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, if applicable, 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), a copy of which shall be provided to any NIMS
      Insurer, 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.

    Section
      10.03. 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 of its duties and obligations set forth herein,
      the
      Trustee shall indemnify the NIMS Insurer and the Holder of the related Residual
      Certificate 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 NIMS Insurer, the Depositor, or the Holder of such
      Residual Certificate or any other party, as applicable, nor for any such Losses
      resulting from misinformation provided by the Master Servicer, 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 pursuant to this Section 10.03 (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 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 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 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.

    
      
        
        

      

      
        159

        
          

        

      

      
        
        

      

    

    


    (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 (b) the Master Servicer, acting on behalf
      of the Trustee 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 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.

    MISCELLANEOUS
      PROVISIONS

    


    Section
      11.01. Binding
      Nature of Agreement; Assignment.

    


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

    


    Section
      11.02. Entire
      Agreement.

    


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

    


    Section
      11.03. Amendment.

    


    (a) This
      Agreement may be amended from time to time by the Depositor, the Master Servicer
      and the Trustee, with the consent of the NIMS Insurer, but without the consent
      of any 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 and the NIMS Insurer 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
      and
      the NIMS Insurer receive 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).

    
      
        
        

      

      
        160

        
          

        

      

      
        
        

      

    

    


    (b) This
      Agreement may also be amended from time to time by the Depositor, the Master
      Servicer, the NIMS Insurer and the Trustee, with the consent of the Holders
      of
      not less than 66 2/3% of the Class Principal Amount (or 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 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 Securities Exchange Act of 1934, 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 Notional Amount or
      Percentage Interest), Certificates owned by the Depositor, the Master Servicer,
      the Trustee or any Servicer or Affiliates thereof are not to be counted so
      long
      as such Certificates are owned by the Depositor, the Master Servicer, the
      Trustee or any Servicer or Affiliates thereof.

    


    Section
      11.05. Provision
      of Information.

    


    (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 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 in providing such information shall be reimbursed by
      the
      Depositor.

    


    (b) The
      Trustee will 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 Securities and Exchange Commission pursuant to Section

      the
      Prospectus to the extent in the possession of the Trustee. Any reasonable
      out-of-pocket expenses incurred by the Trustee in providing copies of such

      rights under any Servicing Agreement or of the servicing thereunder or

      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:

    
      
        
        

      

      
        164

        
          

        

      

      
        
        

      

    

    


    (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;

    


    (iii) Such
      successor servicer must be qualified to service loans for FNMA or
      FHLMC;

    


    (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
      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;

    


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

    


    (vii) 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.

    To
      the
      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.

                containing the representations in paragraphs 2, 3 and 4
                hereof.

                provided financial statements or other financial information requested
                by
                the transferor in connection with the transfer of the Residual Certificate

    __________________

    Date

     

    Dear
      Sirs:

     

    In
      connection with our proposed purchase of $______________ principal amount of
      Structured Adjustable Rate Mortgage Loan Trust Mortgage Pass-Through
      Certificates, Series 2007-10 (the “Privately Offered Certificates”) of
      Structured Asset Securities Corporation (the “Depositor”) which are held in the
      form of Definitive Certificates, we confirm that:

     

    1. We
      understand that the Privately Offered Certificates have not been, and will
      not
      be, registered under the Securities Act of 1933, as amended (the “Securities
      Act”), and may not be sold except as permitted in the following sentence. We
      agree, on our own behalf and on behalf of any accounts for which we are acting
      as hereinafter stated, that if we should sell any Privately Offered Certificates
      within two years of the later of the date of original issuance of the Privately
      Offered Certificates or the last day on which such Privately Offered
      Certificates are owned by the Depositor or any affiliate of the Depositor (which
      includes the Placement Agent) we will do so only (A) to the Depositor, (B)
      to
“qualified institutional buyers” (within the meaning of Rule 144A under the
      Securities Act) in accordance with Rule 144A under the Securities Act (“QIBs”),
      (C) pursuant to the exemption from registration provided by Rule 144 under
      the
      Securities Act, or (D) to an institutional “accredited investor” within the
      meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
      Act that is not a QIB (an “Institutional Accredited Investor”) which, prior to
      such transfer, delivers to the Trustee under the Trust Agreement (the “Trust
      Agreement”), dated as of October 1, 2007 among Structured Asset Securities
      Corporation, as Depositor, Aurora Loan Services LLC, as Master Servicer and
      U.S.
      Bank National Association, as Trustee, a signed letter in the form of this
      letter; and we further agree, in the capacities stated above, to provide to
      any
      person purchasing any of the Privately Offered Certificates from us a notice
      advising such purchaser that resales of the Privately Offered Certificates
      are
      restricted as stated herein.

     

    2. We
      understand that, in connection with any proposed resale of any Privately Offered
      Certificates to an Institutional Accredited Investor, we will be required to
      furnish to the Trustee, the Certificate Registrar and the Depositor a
      certification 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 subject to, the registration requirements of the Securities Act. We further
      understand that the Privately Offered Certificates purchased by us will bear
      a
      legend to the foregoing effect.

     

    3. We
      are
      acquiring the Privately Offered Certificates for investment purposes and not
      with a view to, or for offer or sale in connection with, any distribution in
      violation of the Securities Act. We have such knowledge and experience in
      financial and business matters as to be capable of evaluating the merits and
      risks of our investment in the Privately Offered Certificates, and we and any
      account for which we are acting are each able to bear the economic risk of
      such
      investment.

    
      
        
        

      

      
        G-1

        
          

        

      

      
        
        

      

    

     

    4. We
      are an
      Institutional Accredited Investor and we are acquiring the Privately Offered
      Certificates purchased by us for our own account or for one or more accounts
      (each of which is an Institutional Accredited Investor) as to each of which
      we
      exercise sole investment discretion.

     

    5. We
      have
      received such information as we deem necessary in order to make our investment
      decision.

     

    6. If
      we are
      acquiring an ERISA-Restricted Certificate, we are not a Plan and we are not
      acquiring the ERISA-Restricted Certificate for, on behalf of or with any assets
      of a Plan, except as may be permitted pursuant to Section 3.03(d) of the Trust
      Agreement.

     

    Terms
      used in this letter which are not otherwise defined herein have the respective
      meanings assigned thereto in the Trust Agreement.

     

    You
      and
      the Depositor and the Trustee are entitled to rely upon this letter and are
      irrevocably authorized to produce this letter or a copy hereof to any interested
      party in any administrative or legal proceeding or official inquiry with respect
      to the matters covered hereby.
