    This
      TRUST AGREEMENT dated as of March 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,
      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 for inclusion in the
      Trust Fund. On the Closing Date, the Depositor will acquire the Certificates
      from the Trust Fund, as consideration for its transfer to the Trust Fund of
      the
      Mortgage Loans and the other property constituting the Trust Fund. The Depositor
      has duly authorized the execution and delivery of this Agreement to provide
      for
      the conveyance to the Trustee of the Mortgage Loans and the other property
      constituting the Trust Fund. All covenants and agreements made by the Depositor,
      the Master Servicer and the Trustee herein with respect to the Mortgage Loans
      and the other property constituting the Trust Fund are for the benefit of the
      Holders from time to time of the Certificates. The Depositor and the Master
      Servicer are entering into this Agreement, and the Trustee is accepting the
      Trust Fund created hereby, for good and valuable consideration, the receipt
      and
      sufficiency of which are hereby acknowledged.

     

    As
      provided herein, the Trustee shall elect that the Trust Fund (excluding the
      Supplemental Prepayment Trust) be treated for federal income tax purposes as
      comprising three real estate mortgage investment conduits (each a “REMIC” or, in
      the alternative, REMIC I, REMIC II and REMIC III (the “Upper Tier REMIC”)). Each
      Underlying REMIC Certificate and each Certificate (other than the Exchange
      and
      Exchangeable Certificates, the Class P Components, the Class LT-R or Class
      R
      Certificate, and exclusive of the right to receive any FPD Premiums in the
      case
      of the Class 1-A2 Certificates), represents ownership of one or more regular
      interests in REMIC III for purposes of the REMIC Provisions. The Class LT-R
      Certificate represents ownership of the sole class of residual interest in
      REMIC
      I for purposes of the REMIC Provisions. The Class R Certificate represents
      ownership of the sole class of residual interest in each remaining REMIC for
      purposes of the REMIC Provisions. 

     

    The
      Upper
      Tier REMIC shall hold as its assets the several Classes of uncertificated Lower
      Tier Interests in REMIC II, other than the Class R-2 Interest, and each such
      Lower Tier Interest is hereby designated as a regular interest in REMIC II.
      REMIC II shall hold as its assets the several Classes of uncertificated Lower
      Tier Interests in REMIC I, and each such Lower Tier Interest is hereby
      designated as a regular interest in REMIC I. REMIC I shall hold as its assets
      the property of the Trust Fund other than the Lower Tier Interests in REMIC
      I
      and REMIC II.

     

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

    REMIC
      I:

     

    REMIC
      I
      shall issue one uncertificated interest in respect of each Mortgage Loan held
      by
      the Trust on the Closing Date, each of which is hereby designated as a regular
      interest in REMIC I (the “REMIC I Regular Interests”). Each REMIC I Regular
      Interest shall have an initial principal balance equal to the Scheduled
      Principal Balance of the Mortgage Loan to which it relates and shall bear
      interest at a per annum rate equal to the Net Mortgage Rate of such Mortgage
      Loan. In the event a Qualified Substitute Mortgage Loan is substituted for
      such
      Mortgage Loan (the “Original Mortgage Loan”), no amount of interest payable on
      such Qualified Substitute Mortgage Loan shall be distributed on such REMIC
      I
      Regular Interest at a rate in excess of the Net Mortgage Rate of the Original
      Mortgage Loan.

     

    On
      each
      Distribution Date the Trustee shall distribute the interest portion of the
      Available Distribution Amount (net of expenses described in the preceding
      paragraph) with respect to each of the Lower Tier Interests in REMIC I based
      on
      the above-described interest rates.

     

    On
      each
      Distribution Date, the Trustee shall distribute the principal portion of the
      Available Distribution Amount among the Lower Tier Interests in REMIC I in
      accordance with the amount of the principal attributable to the Mortgage Loan
      corresponding to each such Lower Tier Interests in REMIC I. All losses on the
      Mortgage Loans shall be allocated among the Lower Tier Interests in REMIC I
      in
      the same manner that principal distributions are allocated.

     

    On
      each
      Distribution Date, the Trustee shall first pay or charge as an expense of REMIC
      I all expenses of the Trust Fund for such Distribution Date.

     

    REMIC
      II

     

    REMIC
      II
      shall hold as assets the REMIC I Regular Interests. REMIC II shall issue the
      several classes of uncertificated REMIC II Interests set out below. Each such
      REMIC II Interest, other than the Class R-2 Interest, is hereby designated
      as a
      regular interest in REMIC II. The following table specifies the Class
      designation, interest rate, and principal amount for each Class of REMIC II
      Interests:

    On

      Distribution Date, the portion of the Available Distribution Amount
      distributable as interest shall be distributed as interest with respect to

      Distribution Date, Net Prepayment Shortfalls and Excess Losses sustained with
      respect to any Collateral Group are to be allocated among the Classes of REMIC
      II Interests related to such Collateral Group based on the relative amounts
      of
      interest otherwise accrued for the related Accrual Period on each such REMIC
      II
      Interest.

     

    On

      Distribution Date, the portion of the Available Distribution Amount
      distributable as principal shall be distributed as principal on REMIC II
      Interests as follows: 

     

    
      	 	
              (1)

            	
              First,

                1,
                to
                the Class LTII-1-GSA Interest until its principal balance equals
                one
                percent of the Group Subordinate Amount for Collateral Group 1 after
                such
                Distribution Date;

            


    

     

    
      	 	
              (2)

            	
              Second,
                from the remaining Available Distribution Amount for Collateral Group
                2,
                to

                one
                percent of the Group Subordinate Amount for Collateral Group 2 after
                such
                Distribution Date;

            


    

     

    
      	 	
              (3)

            	
              Third,
                to
                the
                Class LTII-1-GSA and Class LTII-2-GSA Interests, from the remaining
                Available Distribution Amount for Collateral Group 1 and Collateral
                Group
                2, the minimum amount necessary to cause the ratio of the principal
                balance of each such REMIC II Interest to the principal balances
                of the
                other REMIC II Interest to equal the ratio of the Group Subordinate
                Amount
                related to such REMIC II Interest to the Group Subordinate Amount
                related

                Date;

              Fourth,
                from the remaining Available Distribution Amount from each of the
                Collateral Groups, concurrently, as follows -


            


    

     

    (a) To
      the
      Class LTII-1-Pool until the sum of (a) its principal balance and (b) the
      principal balance of the LTII-1-GSA, after taking into account distributions
      made pursuant to priorities (1) and (3) above, equals the Group Subordinate
      Amount for Collateral Group 1 immediately after such Distribution
      Date;

     


    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    


    (b) To
      the
      Class LTII-2-Pool until the sum of (a) its principal balance and (b) the
      principal balance of the LTII-2-GSA, after taking into account distributions
      made pursuant to priorities (2) and (3) above, equals the Group Subordinate
      Amount for Collateral Group 2 immediately after such Distribution
      Date;

     

    
      	 	
              (5)

            	
              Finally,
                from the remaining Available Distribution Amount from each of the
                Collateral Groups to each REMIC II Interest for which there is a
                Corresponding Class of Certificates until the principal balance of
                such
                REMIC II Interest equals the Class Principal Amount of the Corresponding
                Class of Certificates immediately after such Distribution
                Date.

            


    

     

    For
      each
      Distribution Date, Realized Losses, other than Excess Losses, shall be allocated
      among the REMIC II Interests in the same manner that principal is allocated
      among the REMIC II Interests.

      Class of Certificates constituting an interest in the Trust Fund created
      hereunder (other than the Class P Components, Class LT-R and Class R
      Certificates) is hereby designated (along with each Underlying REMIC
      Certificate) as one or more regular interests in REMIC III. The Class Table
      specifies the Class designation, Certificate Interest Rate, initial Class
      Principal (or Notional) Amount and minimum denomination for (1) each class
      of
      Certificates and (2) for convenience, each Class of Exchange and Exchangeable
      Certificates issued under the Exchange Trust Agreement.

     

    Each
      Class of Underlying REMIC Certificates shall be issued hereunder in
      uncertificated form to the Exchange Trustee, and held in trust pursuant to
      the
      terms of the Exchange Trust Agreement. Classes of Certificates having identical
      characteristics and sharing the same Class designation shall also be issued
      under the Exchange Trust Agreement.

     

    The
      Class
      R Certificate represents ownership of the residual interest in each of REMIC
      II
      and REMIC III and will be issued in a single Certificate representing a 100%
      Percentage Interest in such Class.

     

    The
      Class
      LT-R Certificate will be issued without a Class Principal Amount and will not
      bear interest at a stated rate. The Class LT-R Certificate represents ownership
      of the residual interest in REMIC I and shall be issued as a single Certificate
      evidencing the entire Percentage Interest in such Class.

     

    As
      of the
      Cut-off Date, the Mortgage Loans had an aggregate Scheduled Principal Balance
      of
      $250,589,163.46.

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

     

    If
      on

      appear on the Telerate Page 3750 as of 11:00 a.m. (London time), or if the

      rate first
      from
      Reuters’ “page LIBOR 01,” or if such page is not available, then from
      Bloomberg’s page “BBAM”. If such rate is not published for such LIBOR
      Determination Date, LIBOR for such date will be the most recently published
      Interest Settlement Rate. In the event that the BBA no longer sets an Interest
      Settlement Rate, the Trustee will designate an alternative index that has
      performed, or that the Trustee expects to perform, in a manner substantially
      similar to the BBA’s Interest Settlement Rate. The Trustee will select a
      particular index as the alternative index only if it receives an Opinion of
      Counsel, 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.

      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
      a Substitution Amount shall be paid by the party effecting such substitution
      to
      the Trustee for deposit into the Certificate 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 a Net Mortgage Rate
      within the Net Mortgage Rate parameters of the related Subgroup; (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; provided,
      however,
      in no
      case shall such substitute Mortgage Loan have a remaining stated term to
      maturity later than the Final Scheduled Distribution Date; (iv) (A) has a
      Loan-to-Value Ratio as of the date of such substitution of not greater than
      80%;
provided,
      however,
      that if
      the related Deleted Mortgage Loan has a Loan-to-Value Ratio of greater than
      80%
      as of the date of substitution, then the Loan-to-Value Ratio of such substitute
      Mortgage Loan may be greater than 80% but shall not be greater than the
      Loan-to-Value Ratio of the related Deleted Mortgage Loan and (B) the addition
      of
      such substitute Mortgage Loan does not increase the weighted average
      Loan-to-Value Ratio, as of the date of substitution of the Mortgage Pool by
      more
      than 5%; (v) will comply with all of the representations and warranties relating
      to Mortgage Loans set forth herein, as of the date as of which such substitution
      occurs; (vi) is not a Cooperative Loan unless the related Deleted Mortgage
      Loan
      was a Cooperative Loan; (vii) if applicable, has the same index as and a margin
      not less than that of the related Deleted Mortgage Loan; (viii) has not been
      delinquent for a period of more than 30 days more than once in the twelve months
      immediately preceding such date of substitution; (ix) is covered by a Primary
      Mortgage Insurance Policy if the related Deleted Mortgage Loan is so covered,
      and the Loan-to-Value Ratio of such Mortgage Loan is greater than 80%; and
      (x)
      has a Credit Score not greater than 20 points lower than the Credit Score of
      the
      related Deleted Mortgage Loan; provided,
      however,
      that if
      the Deleted Mortgage Loan does not have a Credit Score, then such substitute
      Mortgage Loan shall have a Credit Score equal to or greater than 700. In the
      event that either one mortgage loan is substituted for more than one Deleted
      Mortgage Loan or more than one mortgage loan is substituted for one or more
      Deleted Mortgage Loans, then (a) the Scheduled Principal Balance referred to
      in
      clause (i) above shall be determined such that the aggregate Scheduled Principal
      Balance of all such substitute Mortgage Loans shall not exceed the aggregate
      Scheduled Principal Balance of all Deleted Mortgage Loans and (b) each of (1)
      the rate referred to in clause (ii) above, (2) the remaining term to stated
      maturity referred to in clause (iii) above, (3) the Loan-to-Value Ratio referred
      to in clause (iv) above and (4) the Credit Score referred to in clause (x)
      above
      shall be determined on a weighted average basis, provided
      that the
      final scheduled maturity date of any Qualifying Substitute Mortgage Loan shall
      not exceed the Final Scheduled Distribution Date of any Class of Certificates.
      Whenever a Qualifying Substitute Mortgage Loan is substituted for a Deleted
      Mortgage Loan pursuant to this Agreement, the party effecting such substitution
      shall certify such qualification in writing to the Trustee. Notwithstanding
      any
      provision herein to the contrary, a Qualifying Substitute Mortgage Loan shall
      be
      deemed to have the same Applicable Fraction as that of the Deleted Mortgage
      Loan
      for which it was substituted.

      respect to the Distribution Date on or after the eighth anniversary but prior
      to
      the ninth anniversary of the first Distribution Date, 45% of the Original Group
      Subordinate Amount and (e) with respect to the Distribution Date on or after

      Collateral Group due during the related Due Period;

     

    (ii) the

      and the proceeds thereof, the Depositor’s rights under any Insurance Policies
      related to the Mortgage Loans, and the Depositor’s security interest in any
      collateral pledged to secure the Mortgage Loans, including the Mortgaged
      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
      and
      shall hold the Trust Fund, as trustee, in trust, for the benefit and use of

    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 Servicing Agreements
      and Transfer Agreements (other than first payment date default or early payment
      date default rights against the related Transferor), to the extent assigned
      under such Mortgage Loan Sale Agreement or the Assignment Agreement (as
      applicable). 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 foregoing sale, transfer,
      assignment, set-over, deposit and conveyance 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
      or any other agreement or instrument relating thereto except as specifically
      set
      forth herein.

    In
      addition, concurrently with the execution and delivery of this Agreement, the
      Depositor does hereby transfer, assign, set over, and otherwise convey to the
      Trustee, without recourse, in trust, all right, title and interest of the
      Depositor in and to the Depositor’s right to receive Prepayment Penalty Amounts

      that regard with respect to the Designated Agreement. Such conveyance includes
      all such amounts received on or after the Cut-off Date.

     

    It
      is
      agreed and understood by the Depositor and the Trustee (and the Depositor 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 be a (i)
“High-Cost Home Loan” as defined in the New Jersey Home Ownership Act effective
      November 27, 2003; (ii) “High-Cost Home Loan” as defined in the New Mexico Home
      Loan Protection Act effective January 1, 2004; (iii) “High-Cost Home Mortgage
      Loans” as defined in the Massachusetts Predatory Home Loan Practices Act
      effective November 7, 2004 and (iv) “High Cost Home Loans” as defined in the
      Indiana Home Loan Practices Act effective January 1, 2005. 

     

    (b) In
      connection with such transfer and assignment, the Depositor does hereby deliver

      and/or any Custodian acting on the Trustee’s behalf, if applicable, the
      following documents or instruments with respect to each Mortgage Loan (each
      a
“Mortgage File”) so transferred and assigned:

     

    (i) with
      respect to each Mortgage Loan, the original Mortgage Note endorsed without
      recourse in proper form to the order of the Trustee, as shown in Exhibit B-4,
      or
      in blank (in each case, with all necessary intervening endorsements as
      applicable);

     

    (ii) the
      original of any guarantee, security agreement or pledge agreement executed
      in
      connection with the Mortgage Note, assigned to the Trustee;

     

    (iii) with

      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,
      a copy of such Mortgage or power of attorney, as the case may be, certified
      to
      be 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
      Certificate of the Depositor certifying that the copy of such Mortgage delivered
      to the Trustee (or the applicable Custodian) is a true copy and that the
      original of such Mortgage has been forwarded to the public recording office,
      or,
      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

      modification or substitution agreement has been delivered for recordation,
      a
      photocopy of such assumption, modification or substitution agreement, pending
      delivery of the original thereof, together with an Officer’s Certificate of the
      Depositor certifying that the copy of such assumption, modification or
      substitution agreement delivered to the Trustee (or the applicable Custodian)
      is

      public recording office;

     

    (v) with
      respect to each Non-MERS Mortgage Loan other than a Cooperative Loan, an
      original Assignment of Mortgage, in form and substance acceptable for recording.
      The Mortgage shall be assigned either (A) in blank, without recourse or (B)
      to
“U.S. Bank National Association, as Trustee of the Lehman Mortgage Trust
      2007-3,” without recourse;

     

    (vi) if
      applicable, such original intervening assignments of the Mortgage, notice of
      transfer or equivalent instrument (each, an “Intervening Assignment”), as may be
      necessary to show a complete chain of assignment from the originator, or, in
      the
      case of an Intervening Assignment that has been lost, a written Opinion of
      Counsel acceptable to the Depositor 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;

     

    (viii) with
      respect to each Mortgage Loan other than a Cooperative Loan, the original
      mortgagee title insurance policy or attorney’s opinion of title and abstract of
      title;

     

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

     

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

     

    


    
      
        
          
          

        

        
          43

          
            

          

        

        
          
          

        

      

    

    


    (xi) in
      connection with any pledge of Additional Collateral, the original additional
      collateral pledge and security agreement executed in connection therewith,
      assigned to the Trustee; and

     

    (xii) with
      respect to any manufactured housing contract, any related manufactured housing
      sales contract, installment loan agreement or participation
      interest.

     

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

     

    (c) (i) Assignments
      of Mortgage with respect to each Non-MERS Mortgage Loan other than a Cooperative
      Loan shall be recorded; provided,
      however,
      that
      such Assignments of Mortgage need not be recorded if, in the Opinion of Counsel
      (which must be from Independent counsel) (which Opinion of Counsel may be in
      the
      form of a memorandum of law) acceptable to the Trustee and the Rating Agencies,
      recording in such states is not required to protect the Trustee’s interest in
      the related Non-MERS Mortgage Loans. Subject to the preceding sentence, as
      soon
      as practicable after the Closing Date (but in no event more than 3 months
      thereafter except to the extent delays are caused by the applicable recording
      office), the Trustee, at the expense of the Depositor and with the cooperation
      of the applicable Servicer, shall cause to be properly recorded by such Servicer
      in each public recording office where the related Mortgages are recorded each
      Assignment of Mortgage referred to in subsection (b)(v) above with respect
      to
      each Non-MERS Mortgage Loan. With respect to each Cooperative Loan, the Trustee,
      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 applicable Servicer, at the expense
      of
      the Depositor and with the cooperation of the Trustee, shall take such actions
      as are necessary to cause the Trustee to be clearly identified as the owner
      of
      each such Mortgage Loan on the records of MERS for purposes of the system of
      recording transfers of beneficial ownership of mortgages maintained by
      MERS.

     

    (d) In
      instances where a Title Insurance Policy is required to be delivered to the
      Trustee, or 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 a Servicer in trust for the benefit of the Trustee and the
      Certificateholders.

    (f) The
      Depositor shall have the right to receive any and all loan-level information
      regarding the characteristics and performance of the Mortgage Loans upon
      request, and to publish, disseminate or otherwise utilize such information
      in
      its discretion, subject to applicable laws and regulations.

     

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

     

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

     

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

     

    (c) If
      in the
      course of the review described in paragraph (b) above the Trustee or the
      applicable Custodian discovers any document or documents constituting a part
      of
      a Mortgage File that is missing, does not appear regular on its face (i.e.,
      is
      mutilated, damaged, defaced, torn or otherwise physically altered) or appears
      to
      be unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule
      (each, a “Material Defect”), the Trustee, or the applicable Custodian on behalf
      of the Trustee, shall promptly identify the Mortgage Loan to which such Material
      Defect relates in the Interim Certification delivered to the Depositor, the
      Master Servicer and the Trustee. Within 90 days of its receipt of such notice,
      the Transferor, or if the Transferor does not do so, the Depositor shall be
      required to cure such Material Defect (and, in such event, the Depositor shall
      provide the Trustee with an Officer’s Certificate confirming that such cure has
      been effected). If the applicable Transferor or the Depositor, as applicable,
      does not so cure such Material Defect, 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 applicable Transferor or 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 applicable Transferor or the Depositor to cure a Material Defect
      if, as determined by the Depositor, upon mutual agreement with the Master
      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.

     

    


    
      
        
          
          

        

        
          45

          
            

          

        

        
          
          

        

      

    

    


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

     

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

     

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


     

    (g) Notwithstanding
      anything to the contrary contained herein, the parties hereto acknowledge that
      the functions of the Trustee with respect to the custody, acceptance, inspection
      and release of Mortgage Files, including but not limited to certain insurance
      policies and documents contemplated by this Agreement or the Servicing
      Agreement(s), and preparation and delivery of the certifications shall be
      performed by the Custodians pursuant to the terms and conditions of the
      Custodial Agreements.

    (h) The
      Trustee, solely in its capacity as Trustee, is hereby authorized and directed
      by

    Section
      2.03. Representations
      and Warranties of the Depositor.

     

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

     

    (i) the
      Depositor is a corporation duly organized, validly existing and in good standing

    (ii) the
      execution and delivery by the Depositor of this Agreement have been duly
      authorized by all necessary corporate action on the part of the Depositor;
      neither the execution and delivery of this Agreement, nor the consummation
      of
      the transactions herein contemplated, nor compliance with the provisions hereof,
      will conflict with or result in a breach of, or constitute a default under,
      any
      of the provisions of any law, governmental rule, regulation, judgment, decree
      or
      order binding on the Depositor or its properties or the certificate of
      incorporation or bylaws of the Depositor;

     

    (iii) the
      execution, delivery and performance by the Depositor of this Agreement and
      the
      consummation of the transactions contemplated hereby do not require the consent
      or approval of, the giving of notice to, the registration with, or the taking
      of
      any other action in respect of, any state, federal or other governmental
      authority or agency, except such as has been obtained, given, effected or taken
      prior to the date hereof;

     

    (iv) this
      Agreement has been duly executed and delivered by the Depositor and, assuming
      due authorization, execution and delivery by the Trustee and the Master
      Servicer, constitutes a valid and binding obligation of the Depositor

      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 LBH
      under
      the Mortgage Loan Sale Agreement, the only right or remedy of the Trustee or
      of
      any Certificateholder shall be the Trustee’s right to enforce the obligations of
      the applicable Transferor under any applicable representation or warranty made
      by it. The Trustee acknowledges that LBH shall have no obligation or liability
      with respect to any breach of a representation or warranty made by it with
      respect to the Mortgage Loans if the fact, condition or event constituting
      such
      breach also constitutes a breach of a representation or warranty made by the
      applicable Transferor in the applicable Transfer Agreement, without regard
      to
      whether such Transferor fulfills its contractual obligations in respect of
      such
      representation or warranty. The Trustee further acknowledges that the Depositor
      shall have no obligation or liability with respect to any breach of any
      representation or warranty with respect to the Mortgage Loans (except as set
      forth in Section 2.03(a)(vi)) under any circumstances.

     

    Section
      2.04. Discovery
      of Breach.

     

    It
      is
      understood and agreed that the representations and warranties (i) of the
      Depositor set forth in Section 2.03 hereof, (ii) of LBH set forth in the
      Mortgage Loan Sale Agreement and assigned to the Trustee by the Depositor
      hereunder and (iii) of each Transferor, assigned by LBH 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,
      the Master Servicer, or a Responsible Officer of 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 Loan Services LLC 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 notice of discovery
      of a breach of any representation or warranty given to the Trustee by the
      Depositor, any Transferor or LBH and assigned to the Trustee hereunder, the
      Depositor, such Transferor or LBH 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 in the case of a
      First Payment Default Mortgage Loan, the FPD 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 the 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 the
      Certificateholders. As provided in the Mortgage Loan Sale Agreement, if any
      Transferor substitutes for a Mortgage Loan for which there is a breach of any
      representations and warranties in the related Transfer Agreement which adversely
      and materially affects the value of such Mortgage Loan and such substitute
      mortgage loan is not a Qualifying Substitute Mortgage Loan, under the terms
      of
      the Mortgage Loan Sale Agreement, LBH will, in exchange for such Substitute
      Mortgage Loan, either (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 LBH pursuant to the Mortgage Loan Sale Agreement or by any
      Transferor pursuant to the applicable Transfer Agreement, the principal portion
      of the funds (including the FPD Purchase Price in the case of any First Payment
      Default Mortgage Loan) received by the Trustee in respect of such repurchase
      of
      a Mortgage Loan will be considered a Principal Prepayment and the Purchase
      Price
      or FPD Purchase Price, as applicable, shall be deposited in the Certificate
      Account. The Trustee, upon receipt by LBH or a Transferor of the full amount
      of
      the Purchase Price for a Deleted Mortgage Loan, or upon its receipt of
      notification from the applicable Custodian that it has received the Mortgage
      File for a Qualifying Substitute Mortgage Loan substituted for a Deleted
      Mortgage Loan (and any applicable Substitution Amount), shall release or cause
      to be released and reassigned to the Depositor, LBH 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 applicable Servicer or the Trustee (or the applicable
      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 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 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 (i) any federal or state tax to be imposed on the
      Trust Fund, including without limitation, any federal tax imposed on “prohibited
      transactions” under Section 860F(2) of the Code, or (ii) any REMIC created
      hereunder to fail to qualify as a REMIC at any time that any Certificate is
      outstanding.

     

    


    
      
        
          
          

        

        
          49

          
            

          

        

        
          
          

        

      

    

    


    (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 LBH 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, 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 such Servicer shall,
      with respect to a Qualifying Substitute Mortgage Loan that is a MERS Mortgage
      Loan, cause to be taken such actions as are necessary to cause the Trustee
      to be
      clearly identified as the owner of each such Mortgage Loan on the records of
      MERS if required pursuant to Section 2.01(c)(ii).

     

    (c) Notwithstanding
      any other provision of this Agreement, the right to substitute Mortgage Loans
      pursuant to this Article II shall be subject to the additional limitations
      that
      no substitution of a Qualifying Substitute Mortgage Loan for a Deleted Mortgage
      Loan shall be made unless the Trustee has received an Opinion of Counsel (at
      the
      expense of the party seeking to make the substitution) that, under current
      law,
      such substitution will not (A) affect adversely the status of any REMIC
      established hereunder as a REMIC, or of the related “regular interests” as
“regular interests” in any such REMIC, or (B) cause any such REMIC to engage in
      a prohibited transaction or prohibited contribution pursuant to the REMIC
      Provisions.

    

      Section
        2.06. Grant
        Clause.

       

    

    


    
      
        
          
          

        

        
          50

          
            

          

        

        
          
          

        

      

    

     

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

     

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

    ARTICLE
      III


     

    THE
      CERTIFICATES

     

    Section
      3.01. The
      Certificates.

     

    (a) The
      Certificates shall be issuable in registered form only and shall be securities
      governed by Article 8 of the New York Uniform Commercial Code. The Book-Entry
      Certificates will be evidenced by one or more certificates, beneficial ownership
      of which will be held in the dollar denominations in Certificate Principal
      Amount or Notional Amount, as applicable, or in the Percentage Interests,
      specified herein. Each Class of Book-Entry Certificates shall be issued in
      the
      minimum denominations in Certificate Principal Amount (or Notional Amount)
      or
      Percentage Interest specified in the Preliminary Statement hereto and in
      integral multiples of $1 or 5% (in the case of Certificates issued in Percentage
      Interests) in excess thereof. Each Class of Non-Book Entry Certificates other
      than the Residual Certificate shall be issued in definitive, fully registered
      form in the minimum denominations in Certificate Principal Amount (or Notional
      Amount) specified in the Preliminary Statement hereto and in integral multiples
      of $1 in excess thereof. The Residual Certificates shall each be issued as
      a
      single Certificate and maintained in definitive, fully registered form in a
      minimum denomination equal to 100% of the Percentage Interest of such Class.
      The
      Certificates may be issued in the form of typewritten certificates. One
      Certificate of each Class of Certificates other than any Class of Residual
      Certificates may be issued in any denomination in excess of the minimum
      denomination.

     

    (b) The
      Certificates shall be executed by manual or facsimile signature on behalf of
      the
      Trustee by an authorized signatory. Each Certificate shall, on original issue,
      be authenticated by the Trustee upon the order of the Depositor upon receipt
      by
      the Trustee (or the Custodian on its behalf) 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 signatory of the Trustee or the Authenticating Agent,
      if any, by manual signature, and such certification upon any Certificate shall
      be conclusive evidence, and the only evidence, that such Certificate has been
      duly authenticated and delivered hereunder. All Certificates shall be dated
      the
      date of their authentication. At any time and from time to time after the
      execution and delivery of this Agreement, the Depositor may deliver Certificates
      executed by the Depositor to the Trustee or the Authenticating Agent for
      authentication and the Trustee or the Authenticating Agent shall authenticate
      and deliver such Certificates as in this Agreement provided and not otherwise.

    (c) The
      Privately Offered Certificates offered and sold in reliance on the exemption
      from registration under Rule 144A under the Securities 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, in the case of the Privately Offered
      Certificates, 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 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, in
      the case of the Privately Offered Certificates, 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 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.

     

    The
      Privately Offered Certificates sold to an “accredited investor” 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, Certificate
      Registrar in respect of the Certificates (and, after a Section 7.01(c) Purchase
      Event, the Lower Tier REMIC I Uncertificated Regular Interests, if applicable)
      and shall maintain books for the registration and for the transfer of
      Certificates (and, after a Section 7.01(c) Purchase Event, the Lower Tier REMIC
      I Uncertificated Regular Interests, if applicable) (the “Certificate Register”).
      A registration book shall be maintained for the Certificates (and, after a
      Section 7.01(c) Purchase Event, the Lower Tier REMIC I Uncertificated Regular
      Interests, if applicable) collectively. The Certificate Registrar may resign
      or
      be discharged or removed and a new successor may be appointed by the Trustee
      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.

    


    Upon
      the
      occurrence of a Section 7.01(c) Purchase Event, the Master Servicer shall
      provide the Trustee with written notice of the identity of any transferee of
      the
      Master Servicer’s interest in the Lower Tier REMIC I Uncertificated Regular
      Interests, which notice shall contain a certification that such transferee
      is
      permitted LTURI holder. The Lower Tier REMIC I Uncertificated Regular Interests
      may only be transferred in whole and not in part to no more than one LTURI
      holder at a time who is either (1) an affiliate of the Master Servicer or (2)
      a
      trustee of a privately placed securitization. The Trustee and the Depositor
      shall treat the Person in whose name the Lower Tier REMIC I Uncertificated
      Regular Interests are registered on the books of the Certificate Registrar
      as
      the LTURI holder for all purposes hereunder.

    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 (except as provided in the Exchange Trust
      Agreement), but the Certificate Registrar may require payment of a sum
      sufficient to cover any tax or governmental charge that may be imposed in
      connection with any exchange of Certificates. Whenever any Certificates are
      so
      surrendered for exchange, the Trustee shall execute, and the Trustee or the
      Authenticating Agent shall authenticate, date and deliver the Certificates
      which
      the Certificateholder making the exchange is entitled to receive.

     

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

     

    


    
      
        
          
          

        

        
          54

          
            

          

        

        
          
          

        

      

    

    


    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, the Servicers or the Placement
      Agent or to an affiliate (as defined in Rule 405 under the Securities Act)
      of
      the Depositor or the Placement Agent or (y) being made to a QIB by a transferor
      that has provided the Trustee 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 Securities Act by a transferor who
      furnishes to the Trustee a letter of the transferee substantially in the form
      of
      Exhibit G hereto.

     

    (d) No
      transfer of an ERISA-Restricted Certificate in the form of a Definitive
      Certificate shall be made to any Person or shall be effective unless the Trustee
      has received (A) a certificate substantially in the form of Exhibit H hereto
      (or
      Exhibit D-1, in the case of a Residual Certificate) from such transferee or
      (B)
      other than in the case of the Class 1-A5 and Class 1-A6 Certificates, an Opinion
      of Counsel reasonably satisfactory to the Trustee to the effect that the
      purchase and holding of such a Certificate will not constitute or result in
      prohibited transactions under Title I of ERISA or Section 4975 of the Code
      and
      will not subject the Trustee, the Master Servicer or the Depositor to any
      obligation in addition to those undertaken in the Agreement; provided,
      however,
      that
      the Trustee will not require such certificate or opinion in the event that,
      as a
      result of a change of law or otherwise, the Trustee receives an Opinion of
      Counsel to the effect that the purchase and holding of an ERISA-Restricted
      Certificate by a Plan or a Person that is purchasing or holding such a
      Certificate with the assets of a Plan will not constitute or result in a
      prohibited transaction under Title I of ERISA or Section 4975 of the Code.
      Each
      Transferee of an ERISA-Restricted Certificate that is a Book-Entry Certificate
      shall be deemed to have made the representations set forth in Exhibit H. The
      preparation and delivery of the certificate and opinions referred to above
      shall
      not be an expense of the Trust Fund, the Trustee, the Master Servicer or the
      Depositor.

     

    


    
      
        
          
          

        

        
          55

          
            

          

        

        
          
          

        

      

    

    


    Notwithstanding
      the foregoing, no opinion or certificate shall be required for the initial
      issuance of the ERISA-Restricted Certificates. The Trustee shall have no
      obligation to monitor transfers of Book-Entry Certificates that are
      ERISA-Restricted Certificates and shall have no liability for transfers of
      such
      Certificates in violation of the transfer restrictions. The Trustee shall be
      under no liability to any Person for any registration of transfer of any
      ERISA-Restricted Certificate that is in fact not permitted by this Section
      3.03(d) or for making any payments due on such Certificate to the Holder thereof
      or taking any other action with respect to such Holder under the provisions
      of
      this Agreement so long as the transfer was registered by the Trustee in
      accordance with the foregoing requirements. The Trustee shall be entitled,
      but
      not obligated, to recover from any Holder of any ERISA-Restricted Certificate
      that was in fact a Plan or a Person acting on behalf of a Plan any payments
      made
      on such ERISA-Restricted Certificate at and after either such time. Any such
      payments so recovered by the Trustee shall be paid and delivered by the Trustee
      to the last preceding Holder of such Certificate that is not such a Plan or
      Person acting on behalf of a Plan.

     

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

     

    (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 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”).

     

    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 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. The Trustee shall not
      be
      under any liability to any person for any registration or transfer of a Residual
      Certificate to a Disqualified Organization, agent or nominee thereof, or
      Non-permitted Foreign Holder or for the maturity of any payments due on such
      Residual Certificate to the Holder thereof or for taking any other action with
      respect to such Holder under the provisions of the Agreement, so long as the
      transfer was effected in accordance with this Section 3.03(f), unless a
      Responsible Officer of the Trustee shall have actual knowledge at the time
      of
      such transfer or the time of such payment or other action that the transferee
      is
      a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign
      Holder. The Trustee shall be entitled to recover from any Holder of a Residual
      Certificate that was a Disqualified Organization, agent or nominee thereof,
      or
      Non-permitted Foreign Holder at the time it became a Holder or any subsequent
      time it became a Disqualified Organization, agent or nominee thereof, or
      Non-permitted Foreign Holder, all payments made on such Residual Certificate
      at
      and after either such times (and all costs and expenses, including but not
      limited to attorneys’ fees, incurred in connection therewith). Any payment (not
      including any such costs and expenses) so recovered by the Trustee shall be
      paid
      and delivered to the last preceding Holder of such Residual
      Certificate.

     

    


    
      
        
          
          

        

        
          56

          
            

          

        

        
          
          

        

      

    

    


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

     

    (g) Each
      Holder 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).

     

    


    
      
        
          
          

        

        
          57

          
            

          

        

        
          
          

        

      

    

     

    (A) Subject
      to clauses (B) and (C) 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.

     

    (B) Restricted
      Global Security to Regulation S Global Security.
      If a
      holder of a beneficial interest in a Restricted Global Security deposited with
      or on behalf of DTC wishes at any time to exchange its interest in such
      Restricted Global Security for an interest in a Regulation S Global Security,
      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 Trustee,
      as
      Certificate Registrar, of (I) instructions from DTC directing the Trustee,
      as
      Certificate Registrar, to cause 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 N-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
      Regulation S Global Securities, including that the holder is not a U.S. person,
      and pursuant to and in accordance with Regulation S, the Trustee, as 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.

     

    (C) Regulation
      S Global Security to Restricted Global Security.
      If a
      holder of a beneficial interest in a Regulation S Global Security deposited
      with
      or on behalf of DTC wishes at any time to transfer its interest in such
      Regulation S Global Security to a Person who wishes to take delivery thereof
      in
      the form of an interest in a Restricted Global Security, such holder may,
      subject to the rules and procedures DTC, exchange or cause the exchange of
      such
      interest for an equivalent beneficial interest in a Restricted Global Security.
      Upon receipt by the Trustee, as Certificate Registrar, of (I) instructions
      from
      DTC directing the Trustee, as 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 N-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 Securities Act and in accordance
      with any applicable securities laws of any State of the United States or any
      other jurisdiction, then the Trustee, as 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 Trustee, as 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.

     

    


    
      
        
          
          

        

        
          58

          
            

          

        

        
          
          

        

      

    

    


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

     

    (E) Restrictions
      on U.S. Transfers.
      Transfers of interests in a 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)(C).

     

    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 Certificate Registrar.

     

    Section
      3.05. Replacement
      of Certificates.

    


    If
      (i)
      any Certificate is mutilated and is surrendered to the Trustee or any
      Authenticating Agent or (ii) the Trustee or any Authenticating Agent receives
      evidence to its satisfaction of the destruction, loss or theft of any
      Certificate, and there is delivered to 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 Trustee and any Authenticating
      Agent that such destroyed, lost or stolen Certificate has been acquired by
      a
bona
      fide
      purchaser, the Trustee shall execute and the Trustee or any Authenticating
      Agent
      shall authenticate and deliver, in exchange for or in lieu of any such
      mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
      tenor and Certificate Principal Amount (or Notional 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, 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, the Certificate Registrar nor any agent of any
      of
      them shall be affected by notice to the contrary.

     

    Section
      3.07. Temporary
      Certificates.

     

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

     

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

    


    Section
      3.08. Appointment
      of Paying Agent.

     

    


    
      
        
          
          

        

        
          60

          
            

          

        

        
          
          

        

      

    

     

    The
      Trustee may appoint a Paying Agent (which may be the Trustee) 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, on behalf of the Trustee, in trust
      for the benefit of the Certificateholders entitled thereto until such sums
      shall
      be paid to the Certificateholders. All funds remitted by the Trustee to any
      such
      Paying Agent for the purpose of making distributions shall be paid to
      Certificateholders on each Distribution Date and any amounts not so paid shall
      be returned on such Distribution Date to the Trustee. If the Paying Agent is
      not
      the Trustee, the Trustee shall cause to be remitted to the Paying Agent on
      or
      before the Business Day prior to each Distribution Date, by wire transfer in
      immediately available funds, the funds to be distributed on such Distribution
      Date. Any Paying Agent shall be either a bank or trust company or otherwise
      authorized under law to exercise corporate trust powers. As of the Closing
      Date,
      the Trustee is the Paying Agent.

     

    At
      any time during the period that a Form 10-K is being filed with respect to
      the
      Trust in accordance with the Exchange Act and the rules and regulations of
      the
      Commission, the Trustee shall not appoint a Paying Agent that is not the Trustee
      unless that Paying Agent first agrees in writing with the Trustee (i) to deliver
      an assessment of compliance and an accountant’s attestation in such manner and
      at such times in compliance with Section 9.25(a) and 9.25(b) of this Agreement,
      (ii) to comply with the provisions of Section 9.25(a), 9.25(b), 6.20(e)(i)
      and
      6.20(e)(iv)of this Agreement and (iii) to indemnify the Depositor and the Master
      Servicer, and their respective directors, officers, employees and agents and
      the
      Trust Fund and hold each of them harmless as set forth in Section 6.23. For
      so
      long as the Depositor is subject to Exchange Act reporting requirements with
      respect to the Trust, the Paying Agent (if other than the Trustee) shall give
      prior written notice to the Sponsor, the Master Servicer, the Trustee and the
      Depositor of the appointment of any Subcontractor by it and a written
      description (in form and substance reasonably satisfactory to the Sponsor and
      the Depositor) of the role and function of each Subcontractor utilized by the
      Paying Agent, as applicable, 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 Subcontractor. In addition, for so long as the Depositor is
      subject to Exchange Act reporting requirements with respect to the Trust, the
      Paying Agent (including the Trustee in its capacity as Paying Agent, to the
      extent not already required of the Trustee under this Agreement) shall notify
      the Sponsor, the Master Servicer, the Trustee and the Depositor within five
      (5)
      calendar days of knowledge thereof (i) of any legal proceedings pending under
      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 I hereto or any of their
      affiliates. On or before March 1st
      of each year, the Depositor shall distribute the information in Exhibit I to
      the
      Paying Agent.

     

    


    
      
        
          
          

        

        
          61

          
            

          

        

        
          
          

        

      

    

    


    Any
      Paying Agent (if other than the Trustee) agrees to indemnify the Depositor,
      the
      Trustee (if other than the Paying Agent) and the Master Servicer, and each
      of
      their respective directors, officers, employees and agents and the Trust Fund
      and hold each of them harmless from and against any losses, damages, penalties,
      fines, forfeitures, legal fees and expenses and related costs, judgments, and
      any other costs, fees and expenses that any of them may sustain arising out
      of
      or based upon the failure by such Paying Agent to deliver any information,
      report or certification when and as required under Section 6.20 and Section
      9.25(a). This indemnification shall survive the termination of this Agreement
      or
      the termination of such Paying Agent hereunder.

     

    In
      addition, the Paying Agent (if other than the Trustee) (i) may not be an
      originator of Mortgage Loans, the Master Servicer, a Servicer, the Depositor
      or
      an affiliate of the Depositor unless the Paying Agent is in an institutional
      trust department of the Paying Agent, (ii) must be authorized to exercise
      corporate trust powers under the laws of its jurisdiction of organization and
      (iii) must be rated at least “A/F1” by Fitch, if Fitch is a Rating Agency that
      has rated the Paying Agent, or the equivalent rating by S&P. If no successor
      Paying Agent shall have been appointed and shall have accepted appointment
      within 60 days after the Paying Agent ceases to be the Paying Agent pursuant
      to
      this Section 3.08, then the Trustee shall perform the duties of the Paying
      Agent
      pursuant to this Agreement. The Trustee shall notify the Rating Agencies of
      any
      change of Paying Agent.

     

    Section
      3.09. Book-Entry
      Certificates.

     

    (i) 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, or its custodian,
      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):

     

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

     

    (iii) 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;

     

    (iv) 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

     

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

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

     

    (c) If
      (i)
      (A) the Depositor advises the Trustee in writing that the Clearing Agency is
      no
      longer willing or able to discharge properly its responsibilities with respect
      to the Book-Entry Certificates, and (B) the Trustee or the Depositor is unable
      to locate a qualified successor or (ii) after the occurrence of an Event of
      Default, Certificate Owners representing beneficial interests aggregating not
      less than 50% of the Class Principal Amount (or Class Notional Amount) of a
      Class of Book-Entry Certificates identified as such to the Trustee by an
      Officer’s Certificate from the Clearing Agency advise the Trustee and the
      Clearing Agency through the Clearing Agency Participants in writing that the
      continuation of a book-entry system through the Clearing Agency is no longer
      in
      the best interests of the Certificate Owners of a Class of Book-Entry
      Certificates, the Trustee shall notify or cause the Certificate Registrar to
      notify the Clearing Agency to effect notification to all Certificate Owners,
      through the Clearing Agency, of the occurrence of any such event and of the
      availability of Definitive Certificates to Certificate Owners requesting the
      same. Upon surrender to the Trustee of the Book-Entry Certificates by the
      Clearing Agency, accompanied by registration instructions from the Clearing
      Agency for registration, the Trustee shall issue the Definitive Certificates.
      Neither the Transferor 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. None of the Seller, the Depositor, the Underwriter, the Master
      Servicer or the Trustee shall have any responsibility for any aspect of the
      records relating to or payments made on account of beneficial ownership
      interests of the Book Entry Certificates held by the Clearing Agency or for
      maintaining, supervising or reviewing any records relating to such beneficial
      ownership interests.

      3.10. Deposit
      of Underlying REMIC Certificates under the Exchange Trust

    ADMINISTRATION
      OF THE TRUST FUND

     

    Section
      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 Lehman Mortgage Trust Mortgage Pass-Through Certificates, Series 2007-3.” The
      Collection Account shall relate solely to the Certificates issued by the Trust
      Fund hereunder, and funds in such Collection Account shall not be commingled
      with any other monies.

     

    (b) The
      Collection Account shall be an Eligible Account. If an existing Collection
      Account ceases to be an Eligible Account, the Master Servicer shall establish
      a
      new Collection Account that is an Eligible Account within 30 days and transfer
      all funds on deposit in such existing Collection Account into such new
      Collection Account.

     

    (c) The
      Master Servicer shall give to the Trustee prior written notice of the name
      and
      address of the depository institution at which the Collection Account is
      maintained and the account number of such Collection Account. No later than
      2:00
      p.m. New York City time on each Master Servicer Remittance Date, the entire
      amount on deposit in the Collection Account (subject to permitted withdrawals
      set forth in Section 4.02), excluding any amounts that are not included in
      the
      Available Distribution Amount for such Distribution Date (other than amounts
      due
      or reimbursable to the Trustee or 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
      and
      with prior notice to the Trustee, may choose to make daily remittances from
      the
      Collection Account to the Trustee for deposit into the Certificate
      Account.

     

    (d) The
      Master Servicer shall deposit or cause to be deposited into the Collection
      Account, no later than two Business Days following the Closing Date, any amounts
      representing Scheduled Payments on the Mortgage Loans due after the Cut-off
      Date
      and received by the Master Servicer on or before the Closing Date. Thereafter,
      the Master Servicer shall deposit or cause to be deposited in the Collection
      Account on the earlier of the applicable Master Servicer 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
      Mortgage Loans due on or before the Cut-off Date):

     

    (i) all
      payments on account of principal, including Principal Prepayments and late
      collections, as indicated in the Mortgage Loan Schedule, 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;

     

    


    
      
        
          
          

        

        
          64

          
            

          

        

        
          
          

        

      

    

     

    (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; provided
      that if
      the applicable Servicer is also the Retained Interest Holder with respect to
      any
      Mortgage Loan, payments on account of interest on the Mortgage Loans as to
      which
      such Servicer is the Retained Interest Holder may also be made net of the
      related Retained Interest with respect to each such Mortgage Loan.

     

    (iv) all
      Insurance Proceeds;

     

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

     

    (vi) all
      proceeds of any Mortgage Loan purchased by any Person and any Substitution
      Amounts related to any Qualifying Substitute Mortgage Loan; and

     

    (vii) the
      Purchase Price or FPD Purchase Price (including any FPD Premium) 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

     

    (viii) all
      Prepayment Penalty Amounts received in respect of the Designated Mortgage
      Loans.

     

    (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 the earlier of (a) the Master Servicer Remittance Date or (b) the day
      on
      which the funds in such Collection Account are required to be remitted to the
      Trustee for deposit into the Certificate Account, 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 the Certificates. All income
      and
      gain realized from any such investment shall be for the benefit of the Master
      Servicer as compensation and shall be subject to its withdrawal on 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 the 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 the Collection Account.

      4.02. Application
      of Funds in the Collection Account.

     

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

     

    (i) to
      reimburse itself or any Servicer for Advances made by it or by such Servicer
      pursuant to Section 5.04 or the applicable Servicing Agreement; provided,
      however,
      that the
      Master Servicer’s right to reimburse itself pursuant to this subclause 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; provided,
      further,
      that
      following the final liquidation of a Mortgage Loan, the Master Servicer may
      reimburse itself for previously unreimbursed Advances in excess of Liquidation
      Proceeds or Insurance Proceeds with respect to such Mortgage Loans from any
      funds in the Collection Account, 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 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 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) to
      reimburse itself or any Servicer for expenses incurred by and recoverable by
      or
      reimbursable to it or such Servicer pursuant to Section 9.04, 9.05, 9.06, 9.16
      or 9.22(a) or pursuant to the applicable Servicing Agreement, and to reimburse
      itself for any expenses reimbursable to it pursuant to Section
      10.01(c);

     

    (v) to
      pay to
      the applicable Person, with respect to each Mortgage Loan or REO Property
      acquired in respect thereof that has been repurchased by such Person pursuant
      to
      this Agreement, all amounts received thereon and not distributed on the date
      on
      which the related repurchase was effected, and to pay to the applicable Person
      any Advances and Servicing Advances to the extent specified in the definition
      of
      Purchase Price, any FPD Premium, or any amounts paid by LBH for shortfalls
      in
      the Purchase Price for repurchases of First Payment Default Mortgage Loans
      pursuant to Section 1.04(f) of the Mortgage Loan Sale Agreement relating to

    (vi) to
      pay to
      itself income earned on the investment of funds deposited in the Collection
      Account;

     

    (vii) to
      make
      payments to the Trustee for deposit into the Certificate Account in the amounts
      and in the manner provided for in Section 4.01(c);

     

    (viii) to
      make
      distributions of any Retained Interest to the Retained Interest Holder on each
      Distribution Date (other than any Retained Interest not deposited into the
      Collection Account in accordance with Section 4.01(d)(iii));

     

    (ix) to
      make
      payment to itself, the Trustee and others pursuant to any provision of this
      Agreement;

     

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

     

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

     

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

     

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

    In
      the
      event that the Master Servicer fails on any Master Servicer Remittance Date
      to
      remit to the Trustee any amounts required to be so remitted to the Trustee
      pursuant to subclause (vii) on 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 Master
      Servicer Remittance Date through the date such funds are remitted to and
      received by the Trustee.

     

    In
      connection with withdrawals pursuant to subclauses (i), (iii), (iv) and (vi)
      above, the Master Servicer’s or Servicer’s entitlement thereto is limited to
      collections or other recoveries on the related Mortgage Loan, except as provided
      herein. 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
      subclauses (i), (iii), (iv) and (vi) above.

    The
      Trustee shall make such report and any additional loan level information (and,
      at its option, any additional files containing the same information in an
      alternative format) available each month to the Certificateholders and the
      Rating Agencies via the Trustee’s internet website. The Trustee’s internet
      website shall initially be located at “www.usbank.com/abs.” Assistance in using
      the website can be obtained by calling the Trustee’s customer service desk at
      (800) 934-6802. Such parties that are unable to use the website are entitled
      to
      have a paper copy mailed to them via first class mail by calling the customer
      service desk and indicating such. The Trustee shall have the right to change
      the
      way such statements are distributed in order to make such distribution more
      convenient and/or more accessible to the above parties and the Trustee shall
      provide timely and adequate notification to all above parties regarding any
      such
      changes.

     

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

     

    (b) Upon
      the
      reasonable advance written request of any Certificateholder that is a savings
      and loan, bank or insurance company, 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 investment in the Certificates;
      provided,
      however,
      that
      the Master Servicer shall be entitled to be reimbursed by such Certificateholder
      for such Master Servicer’s actual expenses incurred in providing such reports
      and access.

     

    (c) Within
      90
      days, or such shorter period as may be required by statute or regulation, after
      the end of each calendar year, the Trustee shall make available to each Person
      who at any time during the calendar year was a Certificateholder of record,
      a
      report summarizing the items provided to Certificateholders pursuant to Section
      4.03(a)(i) and (ii) on an annual basis as may be required to enable such Holders
      to prepare their federal income tax returns. Such information shall include
      the
      amount of original issue discount accrued on each Class of Certificates and
      information regarding the expenses of the Trust Fund. The Trustee shall be
      deemed to have satisfied this requirement if it forwards such information in
      any
      other format permitted by the Code. The Master Servicer shall provide the
      Trustee with such information (to the extent available to the Master Servicer
      pursuant to this Agreement and each Servicing Agreement) as is necessary for
      the
      Trustee to prepare such reports (and the Trustee may rely solely upon such
      information).

    (d) The
      Trustee shall, to the extent reasonably available, furnish any other information
      that is required by the Code and regulations thereunder to be made available
      to
      Certificateholders. The Master Servicer shall, to the extent reasonably
      available, provide the Trustee with such information as is necessary for the
      Trustee to prepare such reports (and the Trustee may rely solely upon such
      information).

     

    (e) So
      long
      as not prohibited by applicable law, the Master Servicer shall provide to the
      Depositor or to any party designated by the Depositor, as promptly as
      practicable upon the Depositor’s request, any and all loan-level information
      that the Depositor may request in any format reasonably requested by the
      Depositor.

    DISTRIBUTIONS
      TO HOLDERS OF CERTIFICATES

     

    Section
      5.01. Distributions
      Generally.

     

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

      however,
      that
      any shortfall in available amounts for such Collateral Group shall be allocated
      among the Classes of Senior Certificates related to such Collateral Group in
      proportion to the amount of Accrued Certificate Interest (as so reduced) that
      would otherwise be distributable thereon;

          76

          
            

          

        

        
          
          

        

      

    

    


    (d) With
      respect to each Class of Subordinate Certificates (other than the Class B1
      Certificates), if on any Distribution Date the Credit Support Percentage for
      that Class is less than the Original Credit Support Percentage for such Class,
      then, notwithstanding anything to the contrary in Section 5.02(a), no
      distribution of amounts described in clauses (ii) and (iii) of the definition
      of
      the related Subordinate Principal Distribution Amount will be made to any
      Subordinate Certificates of lower priority. Any such amounts will be distributed
      proportionately to such Class of Subordinate Certificates entitled to
      distributions in respect such clauses (ii) and (iii) of the definition of
      Subordinate Principal Distribution Amount on such date. Any amount not
      distributed in respect of any Class on any Distribution Date pursuant to the
      immediately preceding paragraph shall be allocated among the remaining Classes
      of Subordinate Certificates in proportion to their respective Class Principal
      Amounts.

     

    (e) On
      each
      Distribution Date, the Trustee shall distribute to the Holder of the Class
      R
      Certificate any amounts remaining in REMIC III for such Distribution Date after
      application of all amounts described in paragraph (a) of this Section 5.02.
      Any
      distributions pursuant to this paragraph (e) shall not reduce the Class
      Principal Amount of the Class R Certificate.

     

    (f) On
      each
      Distribution Date prior to the Credit Support Depletion Date but after the
      date
      on which the total Certificate Principal Amount of the Senior Certificate or
      Certificates (other than any interest-only Certificates) relating to a
      Collateral Group has been reduced to zero, amounts otherwise distributable
      as
      principal on each Class of Subordinate Certificates pursuant to Section
      5.02(a)(iv), in reverse order of priority, in respect of such Class’s
      Subordinate Class Percentage of the Subordinate Principal Distribution Amount
      relating to such retired Certificates, shall be distributed as principal to
      such
      Senior Certificates (other than any interest-only Certificates) remaining
      outstanding pursuant to Section 5.02(a)(iii) until the Class Principal Amounts
      thereof have been reduced to zero, provided
      that on
      such Distribution Date (a) the Aggregate Subordinate Percentage for both
      Collateral Groups for such Distribution Date is less than 200% of such Aggregate
      Subordinate Percentage for the Subordinate Certificates, as of the Cut-off
      Date
      or (b) the average outstanding principal balance of the Mortgage Loans in any
      of
      such Collateral Groups that are delinquent 60 days or more for the last six
      months (including for this purpose any REO Property or Mortgage Loans in
      foreclosure or bankruptcy and the Scheduled Payments that would have been due
      on
      Mortgage Loans with respect to which the related Mortgaged Property has been
      acquired by the Trust Fund if the related Mortgage Loan had remained in
      existence) as a percentage of the related Group Subordinate Amount is greater
      than or equal to 50%.

     

    On
      each
      Distribution Date on which the Class Principal Amounts of the Senior
      Certificates (other than any interest-only Certificates) relating to a
      Collateral Group has been reduced to zero, any amounts distributable pursuant
      to
      this Section 5.02(f) will be allocated, as to each applicable Class of
      Subordinate Certificates, in proportion to such Class’s Subordinate Class
      Percentage of the Subordinate Principal Distribution Amount for the Collateral
      Group relating to each such retired Senior Certificate.

     

    


    
      
        
          
          

        

        
          77

          
            

          

        

        
          
          

        

      

    

    


    On
      each
      Distribution Date on which the Senior Certificates (other than any interest-only
      Certificates) for a Collateral Group remains outstanding, any amounts
      distributable pursuant to this Section 5.02(f) will be distributed in proportion
      to the aggregate Certificate Principal Amount of such Certificates relating
      to
      each such Collateral Group.

     

    (g) (A) On
      any Distribution Date on which the Senior Certificates relating to any
      Collateral Group constitute an Undercollateralized Class or Classes, all amounts
      otherwise distributable as principal on the Subordinate Certificates, in reverse
      order of priority (other than amounts necessary to pay any unpaid Interest
      Shortfalls) (or, following the Credit Support Depletion Date, such other amounts
      described in the immediately following sentence), will be distributed as
      principal to such Undercollateralized Class or Classes pursuant to Section
      5.02(a)(iii), until the total Certificate Principal Amount of the
      Undercollateralized Class or Classes equals the Pool Balance of the related
      Collateral Group, (such distribution, an “Undercollateralization Distribution”).
      In the event that any Senior Certificate or Certificates constitute an
      Undercollateralized Class or Classes on any Distribution Date following the
      Credit Support Depletion Date, Undercollateralization Distributions will be
      made
      from any Available Distribution Amount not related to an Undercollateralized
      Class or Classes remaining after all required amounts have been distributed
      to
      the Senior Certificates related to such other Collateral Groups. In addition,
      the amount of any unpaid Interest Shortfalls with respect to an
      Undercollateralized Class on any Distribution Date (including any Interest
      Shortfalls for such Distribution Date) will be distributed to such
      Undercollateralized Class or Classes prior to the payment of any related
      Undercollateralization Distributions from amounts otherwise distributable as
      principal on the Subordinate Certificates, in reverse order of priority (or,
      following the Credit Support Depletion Date, as provided in the preceding
      sentence).

     

    (B) If
      on any Distribution Date the Senior Certificates relating to more than one
      Collateral Group are Undercollateralized Classes, the distribution described
      in
      paragraph (A) above will be made in proportion to the amount by which the total
      Certificate Principal Amount of the Senior Certificate or Certificates relating
      to each such Collateral Group, after giving effect to distributions pursuant
      to
      Section 5.02(a) on such Distribution Date, exceeds the Pool Balance for the
      related Collateral Group for such Distribution Date.

     

    (h) On
      each
      Distribution Date occurring after a Section 7.01(c) Purchase Event but on or
      prior to a Trust Fund Termination Event, the Trustee (or the Paying Agent on
      behalf of the Trustee), shall withdraw from the Certificate Account the
      Available Distribution Amount (to the extent such amount is on deposit in the
      Certificate Account), and shall allocate such amount to the interests issued
      in
      respect of the Lower Tier REMIC 1 Uncertificated Regular Interests created
      pursuant to this Agreement and shall distribute such amount first, to the
      Trustee, any amounts reimbursable pursuant to Section 4.04(b)(i) and not
      previously reimbursed to the Trustee, second, to the LTURI-holder, any remaining
      Available Distribution Amount to the extent payable on the Lower Tier REMIC
      1
      Uncertificated Regular Interests as provided in the Preliminary Statement,
      and
      third, to the Class LT-R Certificates.

    (i) [Reserved]

     

    (j) On
      each
      Distribution Date, all FPD Premiums to which the Trust Fund is entitled received
      with respect to a First Payment Default Mortgage Loan, shall be distributed
      to
      the Class 1-A2 Certificates.

     

    (k) For
      federal income tax purposes, the Trustee shall treat the beneficial owners
      of
      the Class 1-A2 Certificates (an “FPD Certificate”) as having entered into a
      cash-settled option contract. Pursuant to each cash-settled option contract,
      each FPD Certificate has the right to receive amounts in respect of FPD
      Premiums. Any payments to an FPD Certificate in light of the foregoing shall
      not
      be payments with respect to a “regular interest” in a REMIC within the meaning
      of Code Section 860G(a)(1). Notwithstanding the priority and sources of payments
      set forth in Article V or otherwise, the Trustee shall account for all
      distributions in respect of FPD Premiums on an FPD Certificate as set forth
      in
      this section. For purposes of providing tax information reporting with respect
      to the FPD Certificates, the Trustee shall treat each cash-settled option
      contract described in this paragraph as having a value of $10,000 as of the
      Closing Date.

     

    Section
      5.03. Allocation
      of Realized Losses.

     

    (a) On
      any
      Distribution Date, the related Applicable Fraction of the principal portion
      of
      each Realized Loss (other than any Excess Loss) in respect of a Mortgage Loan,
      shall be allocated in the following order of priority:

     

    first,
      to the
      Class B6 Certificates, in reduction of their Class Principal Amount, until
      the
      Class Principal Amount thereof has been reduced to zero; 

     

    second,
      to the
      Class B5 Certificates, in reduction of their Class Principal Amount, until
      the
      Class Principal Amount thereof has been reduced to zero;

     

    third,
      to the
      Class B4 Certificates, in reduction of their Class Principal Amount, until
      the
      Class Principal Amount thereof has been reduced to zero; 

     

    fourth,
      to the
      Class B3 Certificates, in reduction of their Class Principal Amount, until
      the
      Class Principal Amount thereof has been reduced to zero;

     

    fifth,
      to the
      Class B2 Certificates, in reduction of their Class Principal Amount, until
      the
      Class Principal Amount thereof has been reduced to zero;

     

    sixth,
      to the
      Class B1 Certificates, in reduction of their Class Principal Amount, until
      the
      Class Principal Amount thereof has been reduced to zero; and

     

    seventh,
      to the
      related Classes of Senior Certificates (other than any interest-only
      Certificates), pro
      rata,
      in
      accordance with their respective Class Principal Amounts provided,
      however,
      that
      any Realized Loss (or Excess Loss) allocated to the Class 1-A3 Certificates
      shall instead be allocated to the Class 1-A4 Certificates until the Class
      Principal Amount thereof has been reduced to zero.

     

    


    
      
        
          
          

        

        
          79

          
            

          

        

        
          
          

        

      

    

    


    (b) With
      respect to any Distribution Date, the related Applicable Fraction of the
      principal portion of any Excess Loss in respect of a Mortgage Loan in any
      Collateral Group shall be allocated, pro
      rata,
      to the
      Subordinate Certificates and related Senior Certificate or Certificates (other
      than any interest-only Certificates) on the basis of the Apportioned Principal
      Balances of the Classes of Subordinate Certificates and Class Principal Amounts
      of the Senior Certificates (other than any interest-only Certificates) (and
      in
      the same manner as specified in clause seventh
      of
      subsection (a) above).

     

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

     

    (d) Realized
      Losses allocated in accordance with this Section 5.03 shall be allocated on
      the
      Distribution Date in the month following the month 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, the Subordinate Certificate Writedown Amount for such date
      shall effect a corresponding reduction in the Class Principal Amount of the
      lowest ranking Class of outstanding Subordinate Certificates, which reduction
      shall occur on such Distribution Date after giving effect to distributions
      made
      on such Distribution Date.

     

    (f) In
      addition, any Realized Loss (including any Excess Loss) allocated to an Exchange
      Class shall be proportionately allocated to the related Exchangeable Class
      or
      Classes.

     

    Section
      5.04. Advances
      by the Master Servicer and the Trustee.

     

    (a) Advances
      shall be made in respect of each Master Servicer Remittance 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 cause the
      applicable Servicer to, advance such amount on the Master Servicer Remittance
      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 the applicable
      Servicer has determined would not be recoverable from amounts received with
      respect to such Mortgage Loan, including late payments, Liquidation Proceeds,
      Insurance Proceeds or otherwise. If the Master Servicer determines that an
      Advance is required, it shall on the Master Servicer Remittance 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 Master Servicer Remittance Date to the extent
      that funds in the Certificate Account on such Master Servicer Remittance 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.

     

    


    
      
        
          
          

        

        
          80

          
            

          

        

        
          
          

        

      

    

    


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

     

    Section
      5.05. Compensating
      Interest Payments.

     

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

     

    Section
      5.06. Distributions
      from the Supplemental Prepayment Trust.

     

    A
      separate trust is hereby established (the “Supplemental Prepayment Trust”), the
      corpus of which shall be held by the Trustee, in trust, for the benefit of
      the
      Class 1-A5 and Class 1-A6 Certificateholders. Soft Prepayment Penalties and
      Hard
      Prepayment Penalties in respect of the Designated Mortgage Loans received by
      the
      Trustee and identified as such shall be held separate and apart from, and shall
      not be commingled with, any other monies, including, without limitation, other
      monies of the Trustee held pursuant to this Agreement. Distributions from the
      Supplemental Prepayment Trust shall be made concurrently as
      follows:

     

    


    
      
        
          
          

        

        
          81

          
            

          

        

        
          
          

        

      

    

    


    (a) On
      each
      Distribution Date, the Trustee (or the Paying Agent on behalf of the Trustee),
      shall withdraw from the Supplemental Prepayment Trust, any Soft Prepayment
      Penalties remitted by the Master Servicer to the Trustee in respect of the
      Designated Mortgage Loans on the preceding Master Servicer Remittance Date,
      and
      shall distribute such amount to the Holders of the Class 1-A5 Certificates
      (in
      respect of the Class P Component thereof), regardless of whether the Class
      Notional Amount of the Class I Component thereof has been reduced to zero.
      

     

    (b) On
      each
      Distribution Date, the Trustee (or the Paying Agent on behalf of the Trustee),
      shall withdraw from the Supplemental Prepayment Trust, any Hard Prepayment
      Penalties remitted by the Master Servicer to the Trustee in respect of the
      Designated Mortgage Loans on the preceding Master Servicer Remittance Date,
      and
      shall distribute such amount to the Holders of the Class 1-A6 Certificates
      (in
      respect of the Class P Component thereof), regardless of whether the Class
      Notional Amount of the Class I Component thereof has been reduced to
      zero.

     

    The
      Trustee (or the Paying Agent on behalf of the Trustee) shall make the
      distributions pursuant to this Section 5.06 in respect of the Class P Components
      of the Class 1-A5 and Class 1-A6 Certificates until the earlier to occur of
      (1)
      the termination of the trust fund to which the Designated Mortgage Loans were
      conveyed or (2) the final scheduled maturity date relating to such trust fund,
      which is the distribution date in April 2037.

     

    It
      is the
      intent of the parties hereto that the segregated pool of assets consisting
      of
      any collections in respect of the amounts payable to the Class P Components
      constitutes, for federal income tax purposes, a grantor trust as described
      in
      Subpart E of Part I of Subchapter J of the Code and Treasury Regulation
§301.7701-4(c)(2). 

     

    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, 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 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 its exercise as a prudent Person would exercise
      or
      use under the circumstances in the conduct of such Person’s own affairs, unless
      the Trustee is acting as Master Servicer, in which case it shall use the same
      degree of care and skill as the Master Servicer hereunder.

     

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

     

    


    
      
        
          
          

        

        
          82

          
            

          

        

        
          
          

        

      

    

    


    (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 liable with respect to any action taken, suffered or
      omitted to be taken by it in good faith in accordance with the direction of
      the
      Holders as provided in Section 6.18 hereof;

     

    (ii) For
      all
      purposes under this Agreement, the Trustee shall not be deemed to have notice
      of
      any Event of Default unless a Responsible Officer of the Trustee has actual
      knowledge thereof or unless written notice of any event which is in fact such
      a
      default is received by the Trustee at the address provided in Section 11.07,
      and
      such notice references the Holders of the Certificates and this
      Agreement;

     

    (iii) 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 (i) remit funds (or make Advances) when required to do so or (ii) 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 its
      Corporate Trust Office, and such notice references the Holders of the
      Certificates and this Agreement;

     

    (iv) No
      provision of this Agreement shall require the Trustee to expend or risk its
      own
      funds or otherwise incur any financial liability in the performance of any
      of
      its duties hereunder, or in the exercise of any of its rights or powers, if
      it
      shall have reasonable grounds for believing that repayment of such funds or
      adequate indemnity against such risk or liability is not reasonably assured
      to
      it; and none of the provisions contained in this Agreement shall in any event
      require the Trustee to perform, or be responsible for the manner of performance
      of, any of the obligations of the Master Servicer under this
      Agreement;

     

    


    
      
        
          
          

        

        
          83

          
            

          

        

        
          
          

        

      

    

    


    (v) The
      Trustee shall not be responsible for any act or omission of the Master Servicer,
      any Servicer, the Depositor, the Seller or the Custodian.

     

    (d) The
      Trustee shall have no duty hereunder with respect to any complaint, claim,
      demand, notice or other document it may receive or which may be alleged to
      have
      been delivered to or served upon it by the parties as a consequence of the
      assignment of any Mortgage Loan hereunder; provided,
      however,
      that the
      Trustee shall promptly remit to the Master Servicer upon receipt any such
      complaint, claim, demand, notice or other document (i) which is delivered to
      the
      address of the Trustee provided in Section 11.07 and makes reference to this
      series of Certificate or this Agreement, (ii) of which a Responsible Officer
      has
      actual knowledge, and (iii) which contains information sufficient to permit
      the
      Trustee to make a determination that the real property to which such document
      relates is a Mortgaged Property.

     

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

     

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

     

    (g) The
      Trustee shall not be held liable by reason of any insufficiency in the
      Collection Account resulting from any investment loss on any Eligible Investment
      included therein (except to the extent that the Trustee is the obligor and
      has
      defaulted thereon).

     

    (h) The
      Trustee, except as otherwise provided herein, shall not have any duty (A) to
      see
      to any recording, filing, or depositing of this Agreement or any agreement
      referred to herein or any financing statement or continuation statement
      evidencing a security interest, or to see to the maintenance of any such
      recording or filing or depositing or to any rerecording, refiling or
      redepositing of any thereof, (B) to see to any insurance or claim under any
      Insurance Policy, and (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
      or
      the Supplemental Interest Trust other than from funds available in the
      Certificate Account. Except as otherwise provided herein, the Trustee shall
      not
      have any duty to confirm or verify the contents of any reports or
      certificates of the Master Servicer, or any Servicer 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.

     

    


    
      
        
          
          

        

        
          84

          
            

          

        

        
          
          

        

      

    

    


    (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, neither the Trustee nor any Paying
      Agent shall be liable for special, indirect or consequential losses or damages
      of any kind whatsoever (including, but not limited to, lost profits), even
      if
      the Trustee or such Paying Agent, as applicable, has been advised of the
      likelihood of such loss or damage and regardless of the form of
      action.

     

    (k) For

      resolution, certificate, statement, instrument, opinion, report, notice,
      request, consent, order, approval, bond or other paper or document (provided

      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

      other than its negligence or willful misconduct in the performance of such
      act;
      and

     

    (h) The
      Trustee shall not be required to give any bond or surety in respect of the
      execution of the Trust Fund or Supplemental Interest Trust created hereby or

      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

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

     

    (a) Notwithstanding
      any other provisions hereof, at any time, the Trustee, the Depositor or the
      Certificateholders evidencing more than 50% of the Class Principal Amount (or
      Percentage Interest) of every Class of Certificates shall
      have the power from time to time to appoint one or more Persons, approved by
      the
      Trustee, 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. Notwithstanding the foregoing, if such co-custodian
      or co-trustee is determined to be a Servicing Function Participant no such
      co-custodian or co-trustee shall be vested with any powers, rights and remedies
      under this Agreement unless such party has agreed to comply with all Regulation
      AB requirements set forth under this Agreement or the related Custodial
      Agreement, as applicable.

     

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

     

    (i) all
      powers, duties, obligations and rights conferred upon the Trustee in respect
      of
      the receipt, custody and payment of monies 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;

     

    


    
      
        
          
          

        

        
          90

          
            

          

        

        
          
          

        

      

    

    


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

     

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

     

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

     

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

     

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

     

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

     

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

     

    Section
      6.10. Authenticating
      Agents. 

     

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

     

    


    
      
        
          
          

        

        
          91

          
            

          

        

        
          
          

        

      

    

    


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

     

    (c) Any
      Authenticating Agent may at any time resign by giving at least 30 days’ advance
      written notice of resignation to the Trustee and the Depositor. The Trustee
      may
      at any time terminate the agency of any Authenticating Agent by giving written
      notice of termination to such Authenticating Agent and the Depositor. Upon
      receiving a notice of resignation or upon such a termination, or in case at
      any
      time any Authenticating Agent shall cease to be eligible in accordance with
      the
      provisions of this Section 6.10, the Trustee may appoint a successor
      Authenticating Agent, shall give written notice of such appointment to the
      Depositor and shall mail notice of such appointment to all Holders of
      Certificates. Any successor Authenticating Agent upon acceptance of its
      appointment hereunder shall become vested with all the rights, powers, duties
      and responsibilities of its predecessor hereunder, with like effect as if
      originally named as Authenticating Agent. No successor Authenticating Agent
      shall be appointed unless eligible under the provisions of this Section 6.10.
      No
      Authenticating Agent shall have responsibility or liability for any action
      taken
      by it as such at the direction of the Trustee. Any Authenticating Agent shall
      be
      entitled to reasonable compensation for its services and, if paid by the
      Trustee, it shall be a reimbursable expense 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 its part, arising out of, or in connection with, the
      acceptance or administration of the trusts created hereunder or in connection
      with the performance of its duties hereunder or under the Exchange Trust
      Agreement, the Mortgage Loan Sale Agreement, the Transfer Agreement, any
      Servicing Agreement or the Custodial Agreements, including any applicable fees
      and expenses payable pursuant to Section 6.12 and the costs and expenses of
      defending themselves against any claim in connection with the exercise or
      performance of any of their powers or duties hereunder, provided
      that:

     

    (i) with
      respect to any such claim, the Trustee shall have given the Depositor, the
      Master Servicer and the Holders written notice thereof promptly after a
      Responsible Officer of the Trustee shall have knowledge thereof provided
      that the
      failure to provide such prompt written notice shall not affect the Trustee’s
      right to indemnification hereunder;

     

    


    
      
        
          
          

        

        
          92

          
            

          

        

        
          
          

        

      

    

    


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

     

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

     

    The
      Trustee shall be further indemnified by the Seller for and held harmless
      against, any loss, liability or expense arising out of, or in connection with,
      the provisions set forth in the fourth paragraph of Section 2.01(a) hereof,
      including, without limitation, all costs, liabilities and expenses (including
      reasonable legal fees and expenses) of investigating and defending itself
      against any claim, action or proceeding, pending or threatened, relating to
      the
      provisions of such paragraph.

     

    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 receive, and is authorized to pay itself, any
      investment income and earnings on the Certificate Account. The Trustee shall
      be
      entitled to reimbursement of all reasonable expenses, disbursements and advances
      incurred or made by the Trustee in accordance with this Agreement (including
      fees and expenses of its counsel and all persons not regularly in its employment
      and any amounts described in Section 10.01 to which the Trustee is entitled
      as
      provided therein), except for expenses, disbursements and advances that either
      (i) do not constitute “unanticipated expenses” within the meaning of Treasury
      Regulation Section 1.860G-1(b)(3)(ii) or (ii) arise from its negligence, bad
      faith or willful misconduct. Each Custodian shall receive compensation and
      reimbursement or payment of its expenses under the applicable Custodial
      Agreement as provided therein; provided
      that,
      to the
      extent required under the Custodial Agreement, the Trustee is hereby authorized
      to pay such compensation or indemnity amounts from amounts on deposit in the
      Certificate Account prior to any distributions to Certificateholders pursuant
      to
      Section 5.02 hereof. The provisions of this Section 6.12 shall survive the
      termination of this Agreement and the resignation or removal of the
      Trustee.

     

    Section
      6.13. Collection
      of Monies. 

     

    Except
      as
      otherwise expressly provided in this Agreement, the Trustee may demand payment
      or delivery of, and shall receive and collect, all money and other property
      payable to or receivable by 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 amounts, it may withdraw such
      request.

      the date upon which written notice of such failure shall have been given to
      such
      Master Servicer by the Trustee or to such Master Servicer and the Trustee by
      the
      Holders of not less than 25% of the Class Principal Amount of each Class of

      required to be provided hereunder pursuant to Sections 9.23 and 9.29(b),
      including any items required to be included in any Exchange Act report;
      or

     

    (iv) Any

    (v) A

      for
      the appointment of a conservator or receiver or liquidator in any insolvency,
      readjustment of debt, marshalling of assets and liabilities or similar
      proceedings, or for the winding-up or liquidation of its affairs, shall have
      been entered against the Master Servicer, and such decree or order shall have
      remained in force undischarged or unstayed for a period of 60 days or any Rating
      Agency reduces or withdraws or threatens to reduce or withdraw the rating of

      liabilities, voluntary liquidation or similar proceedings of or relating to
      the
      Master Servicer or of or relating to all or substantially all of its property;
      or

     

    


    
      
        
          
          

        

        
          94

          
            

          

        

        
          
          

        

      

    

    


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

     

    (viii) The
      Master Servicer shall be dissolved, or shall dispose of all or substantially
      all
      of its assets, or consolidate with or merge into another entity or shall permit

    (ix) If
      a
      representation or warranty set forth in Section 9.14 hereof shall prove to
      be
      incorrect as of the time made in any respect that materially and adversely
      affects the interests of the Certificateholders, and the circumstance or
      condition in respect of which such representation or warranty was incorrect
      shall not have been eliminated or cured within 30 days after the date on which
      written notice of such incorrect representation or warranty shall have been
      given to the Master Servicer by the Trustee, or to the Master Servicer and
      the
      Trustee by the Holders of more than 50% of the Aggregate Voting Interests of
      the
      Certificates; 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 and without the prior written consent of the Trustee and
      Certificateholders holding more than 50% of the Aggregate Voting Interests
      of
      the Certificates; or

     

    (xi) The
      Master Servicer has notice or actual knowledge that any Servicer at any time
      is
      not either a Fannie Mae- or Freddie Mac- approved Seller/Servicer, and the
      Master Servicer has not terminated the rights and obligations of such Servicer
      under the applicable Servicing Agreement and replaced such Servicer with a

      Master Servicer receives such notice or acquires such actual
      knowledge.

     

    (xii) After
      receipt of notice from the Trustee, any failure of the Master Servicer to
      deposit into the Certificate Account any payment required to be made for the
      benefit of Certificateholders under the terms of this Agreement, including
      any
      Advance, on the Master Servicer Remittance Date immediately preceding the
      related Distribution Date which such failure continues unremedied for a period
      of one Business Day after the date upon which notice of such failure shall
      have
      been given to the Master Servicer by the Trustee.

     

    If
      an
      Event of Default described in clauses (i) through (xi) of this Section shall
      occur, then, in each and every case, subject to applicable law, so long as
      any
      such Event of Default shall not have been remedied within any period of time
      prescribed by this Section, the Trustee, by notice in writing to the Master
      Servicer may, and shall, if so directed by Certificateholders evidencing more
      than 50% of the Class Principal Amount of each Class of Certificates, terminate
      all of the rights and obligations of the Master Servicer hereunder and in and
      to
      the Mortgage Loans and the proceeds thereof. If an Event of Default described
      in
      clause (xii) of this Section 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, the
      Trustee, by notice in writing to the Master Servicer, shall promptly terminate
      all of the rights and obligations of the Master Servicer hereunder and in and
      to
      the Mortgage Loans and the proceeds thereof. On or after the receipt by the
      Master Servicer of such written notice, all authority and power of the Master
      Servicer, and only in its capacity as Master Servicer under this Agreement,
      whether with respect to the Mortgage Loans or otherwise, shall pass to and
      be
      vested in the Trustee; 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 Servicing 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 (or its designee) for administration
      by it of all amounts which shall at the time be or should have been deposited
      by
      the defaulting Master Servicer and any other account or fund maintained with
      respect to the Certificates or thereafter received with respect to the Mortgage
      Loans. The Master Servicer being terminated (or the Trust Fund, if the Master
      Servicer is unable to fulfill its obligations hereunder) as a result of an
      Event
      of Default shall bear all reasonable costs and expenses 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.

    


    
      
        
          
          

        

        
          95

          
            

          

        

        
          
          

        

      

    

    


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

     

    


    
      
        
          
          

        

        
          96

          
            

          

        

        
          
          

        

      

    

    


    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 to the extent such reimbursement relates to the period prior
      to
      such Master Servicer’s termination.

     

    If
      any
      Event of Default shall occur, the Trustee, upon a Responsible Officer of the
      Trustee becoming aware of the occurrence thereof, shall promptly notify each
      Rating Agency of the nature and extent of such Event of Default. The Trustee
      shall immediately give written notice to the Master Servicer upon the Master
      Servicer’s failure to remit funds to the Trustee on the Master Servicer
      Remittance Date.

     

    (b) On
      and
      after the time the Master Servicer receives a notice of termination from the
      Trustee pursuant to Section 6.14(a) or the Trustee receives the resignation
      of
      the Master Servicer evidenced by an Opinion of Counsel pursuant to Section
      9.28
      but in any event within a period of time not to exceed 90 days after the Master
      Servicer or the Trustee receives such written notice pursuant to Section 6.14(a)
      or Section 9.28, respectively, the Trustee, unless another master servicer
      shall
      have been appointed, shall be the successor in all respects to the Master
      Servicer in its capacity as such under this Agreement and the transactions
      set
      forth or provided for herein and shall have all the rights and powers and be
      subject to all the responsibilities, duties and liabilities relating thereto
      and
      arising thereafter placed on the Master Servicer hereunder, including the
      obligation to make Advances; provided,
      however,
      that
      any failure to perform such duties or responsibilities caused by the Master
      Servicer’s 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 and within a period of time in not
      to
      exceed 90 days after the Master Servicer or the Trustee receives such written
      notice pursuant to Section 6.14(a) or Section 9.28, as applicable. 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.

     

    (c) Notwithstanding
      the above, the Trustee may, if it shall be unwilling to continue to so act,
      or
      shall, if it is unable to so act, petition a court of competent jurisdiction
      to
      appoint, or appoint on its own behalf any established housing and home finance
      institution servicer, master servicer, servicing or mortgage servicing
      institution having a net worth of not less than $15,000,000 and meeting such
      other standards for a successor master servicer as are set forth in this
      Agreement, as the successor to such Master Servicer in the assumption of all
      of
      the responsibilities, duties or liabilities of the Master Servicer hereunder.
      Any entity designated by the Trustee as a successor master servicer may be
      an
      Affiliate of the Trustee; provided,
      however,
      that,
      unless such Affiliate meets the net worth requirements and other standards
      set
      forth herein for a successor master servicer, the Trustee, in its individual
      capacity shall agree, at the time of such designation, to be and remain liable
      to the Trust Fund for such Affiliate’s actions and omissions in performing its
      duties hereunder. In connection with such appointment and assumption, the
      Trustee may make such arrangements for the compensation of such successor out
      of
      payments on Mortgage Loans as it and such successor shall agree; provided,
      however,
      that no
      such compensation shall be in excess of that permitted to the Master Servicer
      hereunder. The Trustee and such successor shall take such actions, consistent
      with this Agreement, as shall be necessary to effectuate any such succession
      and
      may make other arrangements with respect to the servicing to be conducted
      hereunder which are not inconsistent herewith. The Master Servicer shall
      cooperate with the Trustee and any successor master servicer in effecting the
      termination of the Master Servicer’s responsibilities and rights hereunder
      including, without limitation, notifying Mortgagors of the assignment of the
      master servicing functions and providing the Trustee and successor master
      servicer, as applicable, all documents and records in electronic or other form
      reasonably requested by it to enable it to assume the Master Servicer’s
      functions hereunder and the transfer to the Trustee or such successor master
      servicer, as applicable, all amounts which shall at the time be or should have
      been deposited by the Master Servicer in the Collection Account and any other
      account or fund maintained with respect to the Certificates or the Lower Tier
      REMIC 1 Uncertificated Regular Interests 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.

      of
      the Master Servicing Fee or Servicing Fee paid hereunder or under the applicable
      Servicing Agreement and the amount necessary to induce any successor master
      servicer or successor servicer to act as successor master servicer or successor
      servicer under this Agreement or the applicable Servicing Agreement and the
      transactions set forth or provided for herein.

     

    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 the Certificateholders (including the
      institution and prosecution of all judicial, administrative and other
      proceedings and the filings of proofs of claim and debt in connection
      therewith). Except as otherwise expressly provided in this Agreement, no remedy
      provided for by this Agreement shall be exclusive of any other remedy, and
      each
      and every remedy shall be cumulative and in addition to any other remedy, and
      no
      delay or omission to exercise any right or remedy shall impair any such right
      or
      remedy or shall be deemed to be a waiver of any Event of Default.

    Section
      6.16. Waiver
      of Defaults. 

     

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

     

    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. The Trustee shall also, within
      45 days after the occurrence of any Event of Default known to a Responsible
      Officer of the Trustee, give written notice thereof to the Certificateholders,
      unless such Event of Default shall have been cured or waived prior to the
      issuance of such notice and within such 45-day period.

     

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


     

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

    Section
      6.20. Preparation
      of Tax Returns and Other Reports. 

     

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

     

    In
      addition, the Trustee shall prepare, sign and file all of the tax returns in
      respect of the grantor trust referred to in Section 5.06. The expenses of
      preparing and filing such returns shall be borne by the Trustee without any
      right of reimbursement therefor. The Trustee shall comply with each such
      requirement by filing Form 1041 or other applicable form.

     

    (b) The
      Trustee shall prepare and file with the Internal Revenue Service (“IRS”), on
      behalf of the Trust Fund and each of the REMICs specified in the Preliminary
      Statement, an application for an employer identification number on IRS Form
      SS-4
      or by any other acceptable method. The Trustee shall also file a Form 8811
      as
      required. The Trustee, upon receipt from the IRS of the Notice of Taxpayer
      Identification Number Assigned, shall upon request promptly forward a copy
      of
      such notice to the Depositor. The Trustee shall have no obligation to verify
      the
      information in any Form 8811 or Form SS-4 filing.

     

    (c) The
      Depositor shall prepare or cause to be prepared the initial current report
      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 (f) 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), 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. 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 L-1 hereto, within five calendar days after the related
      Distribution Date, (A) certain parties to the transaction contemplated hereby
      shall be required to provide to the Trustee and the Depositor, to the extent
      known by a responsible officer (or with respect to the Trustee, 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 Notification in the form attached hereto as Exhibit L-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.

    


    (iii) After
      preparing the Form 10-D, the Trustee shall forward electronically a 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. The Trustee will make
      available to the Exchange Act Signing Party the monthly statement to
      certificateholders containing the information with respect to exchanges required
      to be included in such report for each Distribution Date and the Exchange Act
      Signing Party shall have the right to ask the Trustee reasonable questions
      regarding any information reported in a certificateholder statement regarding
      any exchange. The Exchange Act Signing Party shall have the right to rely on
      any
      such information provided to it by the Trustee. No later than two Business
      Days
      prior to the 15th
      calendar
      day after the related Distribution Date, a duly authorized representative 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 (g)(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 prepared and 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.

    (iv) Form
      10-D
      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.” At the date of filing of each report
      on Form 10-D with respect to the Trust Fund, the Depositor shall be deemed
      to
      represent to the Trustee that as of such date the Depositor has filed all such
      required reports during the preceding 12 months and that it has been subject
      to
      such filing requirement 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 if the
      answer to the questions should be “no.” The Trustee shall be entitled to rely on
      such representations in preparing, executing and/or filing any such
      report.

    


    (e) Reports
      Filed on Form 10-K.

     

    (i) Within
      90
      days after the end of each fiscal year of the Trust Fund for which the Trust
      Fund is subject to Exchange Act reporting requirements or such earlier date
      as
      may be required by the Exchange Act (the “10-K Filing Deadline”) (it being
      understood that the fiscal year for the Trust Fund ends on December
      31st
      of each
      year), commencing in March 2008, the Trustee shall prepare and file on behalf
      of
      the Trust Fund a Form 10-K, in form and substance as required by the Exchange
      Act. To facilitate the Trustee's preparation of the From 10-K, the Depositor
      shall provide to the Trustee, no later than 30 days prior to the 10-K Filing
      Deadline, a template of the Form-10K in an Edgar-compatible format. Each such
      Form 10-K shall include the following items, in each case to the extent they
      have been delivered to the Trustee within the applicable time frames set forth
      in this Agreement and in the related Servicing Agreements and Custodial
      Agreement, (A) an annual compliance statement for each Servicer, each Additional
      Servicer and the Master Servicer, as described under Section 9.26 hereof and
      in
      each Servicing Agreement, (B)(I) the annual reports on assessment of compliance
      with servicing criteria for each Servicer, the Custodian, each Additional
      Servicer, the Master Servicer, any Servicing Function Participant, the Paying
      Agent (if other than the Trustee) and the Trustee (each, a “Reporting
      Servicer”), as described under Section 9.25(a) hereof and in each Servicing
      Agreement and Custodial Agreement, and (II) if any Reporting Servicer’s report
      on assessment of compliance with servicing criteria described under Section
      9.25(a) hereof or in any Servicing Agreement or Custodial Agreement identifies
      any material instance of noncompliance, disclosure identifying such instance
      of
      noncompliance, or if any Reporting Servicer’s report on assessment of compliance
      with servicing criteria described under Section 9.25(a) hereof or in the any
      Servicing Agreement or Custodial Agreement is not included as an exhibit to
      such
      Form 10-K, disclosure that such report is not included and an explanation why
      such report is not included, (C)(I) the registered public accounting firm
      attestation report for each Reporting Servicer, as described under Section
      9.25(b) hereof and in each Servicing Agreement and Custodial Agreement and
      (II)
      if any registered public accounting 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 any such registered public accounting firm
      attestation report is not included as an exhibit to such Form 10-K, disclosure
      that such report is not included and an explanation why such report is not
      included, and (D) a Sarbanes-Oxley Certification. Any disclosure or information
      in addition to (A) through (D) above that is required to be included on Form
      10-K (“Additional Form 10-K Disclosure”) shall be determined and prepared by and
      at the direction of the Depositor pursuant to the following paragraph and the
      Trustee will have no duty or liability for any failure hereunder to determine
      or

    (ii) As
      set
      forth on Exhibit L-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) certain parties to the transaction contemplated hereby shall be required
      to
      provide to the Trustee and the Depositor, to the extent known by a responsible
      officer (or with respect to the Trustee, 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 L-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 L-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 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 duly authorized representative 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 (g) 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 prepared and 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
      (if
      other than the Trustee) 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 (each, a “Back-Up Certification”), in the form attached hereto as
      Exhibit P (or, in the case of (x) the Paying Agent (if other than the Trustee),
      such other form as agreed to between the Paying Agent and the Exchange Act
      Signing Party), 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 Trustee, the Paying Agent (if other than 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.

    


    (vi) 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.” At the date of filing of each report
      on Form 10-K with respect to the Trust Fund, the Depositor shall be deemed
      to
      represent to the Trustee that as of such date the Depositor has filed all such
      required reports during the preceding 12 months and that it has been subject
      to
      such filing requirement for the past 90 days. The Depositor shall notify the
      Trustee in writing, no later than March 15th
      with
      respect to the filing of a report on Form 10-K, if the answer to the questions
      should be “no.” The Trustee shall be entitled to rely on such representations in
      preparing, executing and/or filing any such report.

    (f) Reports
      Filed on Form 8-K.

     

    (i) Within
      four Business Days after the occurrence of an event requiring disclosure on
      Form
      8-K (each such event, a “Reportable Event”), and if requested by the Depositor,
      the 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) certain
      parties to the transaction contemplated hereby shall be required to provide

      the Trustee and the Depositor, to the extent known by a responsible officer
      thereof (or, with respect to the Trustee, a Responsible Officer thereof), in
      EDGAR-compatible form (which may be Word or Excel documents easily convertible
      to EDGAR format), or in such other form as otherwise agreed upon by the Trustee
      and such party, the form and substance of any Form 8-K Disclosure Information,
      if applicable, and include with such Form 8-K Disclosure Information, an
      Additional Disclosure Notification in the form attached hereto as Exhibit L-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 L-3 of their duties under this paragraph or
      proactively solicit or procure from such parties any Form 8-K Disclosure
      Information. The Sponsor will be responsible for any reasonable fees and
      expenses assessed or incurred by the Trustee in connection with including any
      Form 8-K Disclosure Information on Form 8-K pursuant to this paragraph.


    


    (iii) After
      preparing the Form 8-K, the Trustee shall forward electronically, no later
      than

      Day after the Reportable Event, a copy of the Form 8-K to the Exchange Act
      Signing Party for review and approval. If the Master Servicer is the Exchange
      Act Signing Party, then the Form 8-K shall also be electronically distributed
      to
      the Depositor for review and approval. No later than Noon New York City time
      on
      the 4th
      Business
      Day after the Reportable Event, a senior officer of the Exchange Act Signing
      Party shall sign the Form 8-K and return an electronic or fax copy of such
      signed Form 8-K (with an original executed hard copy to follow by overnight
      mail) to the Trustee. If a Form 8-K cannot be filed on time or if a previously
      filed Form 8-K needs to be amended, the Trustee will follow the procedures
      set
      forth in subsection (g) 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(f). The
      parties to this Agreement acknowledge that the performance by the Trustee of
      its
      duties under this Section 6.20(f) related to the timely preparation and filing
      of Form 8-K is contingent upon such parties strictly observing all applicable
      deadlines in the performance of their duties under this Section 6.20(f). The
      Trustee shall have no liability for any loss, expense, damage, claim arising
      out
      of or with respect to any failure to properly prepare and/or timely file such
      Form 8-K, where such failure results from the Trustee’s inability or failure to
      obtain or receive, on a timely basis, any information from any other party
      hereto needed to prepare, arrange for execution or file such Form 8-K, not
      resulting from its own negligence, bad faith or willful misconduct.

    (g) Suspension
      of Reporting Obligation; Amendments; Late Filings.

     

    (i) On
      or
      before January 30th
      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 with respect to
      an
      additional disclosure item, the Trustee will notify the Depositor and any
      applicable party affected thereby and such parties will cooperate to prepare
      any
      necessary 8-K/A, 10-D/A or 10-K/A. Any Form 15, Form 12b-25 or any amendment
      to
      Form 8-K, 10-D or 10-K shall be signed by a senior officer or a duly authorized
      representative, as applicable, of the Exchange Act Signing Party. The parties
      to
      this Agreement acknowledge that the performance by the Trustee of its duties
      under this Section 6.20(g) related to the timely preparation and filing of
      Form
      15, a Form 12b-25 or any amendment to Form 8-K, 10-D or 10-K is contingent
      upon
      each such party performing its duties under this Section. The 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.

    (h) 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.
      

    


    (i) 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. Any notice delivered
      pursuant to this Section 6.20 may be by fax or electronic copy notwithstanding
      the notice provisions of Section 11.07.

      6.21. [Reserved]

     

    Section
      6.22. No
      Merger. 

     

    (a) The
      Trustee shall not cause or otherwise knowingly permit the assets of the Trust
      Fund to be merged or consolidated with any other entity, except as a result
      of a
      final judicial determination.

     

    Section
      6.23. Indemnification
      by the Trustee and Paying Agent. 

     

    The
      Trustee (including in its capacity as Paying Agent) and any Paying Agent other
      than the Trustee each agrees to indemnify the Depositor 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 engagement by it of any Subcontractor in
      violation of Section 6.01(k) or any failure by it to deliver any assessment
      of
      compliance, information, report or certification when and as required under
      Sections 6.20 or 9.25(a).

     

    Section
      6.24. Compliance
      with Regulation AB.

     

    Each
      of
      the parties hereto acknowledges and agrees that the purpose of Sections 6.01
      and
      6.20 of this Agreement is to facilitate compliance by the Sponsor, the Master
      Servicer, the Depositor and the Trustee with the provisions of Regulation AB,
      as
      such may be amended or clarified from time to time. Therefore, each of the
      parties agrees that (a) the obligations of the parties hereunder shall be
      interpreted in such a manner as to accomplish compliance with Regulation AB,
      (b)
      the parties’ obligations hereunder will be supplemented and modified as
      necessary to be consistent with any such amendments, interpretive advice or
      guidance from the Commission, convention or consensus among active participants
      in the asset-backed securities markets, or otherwise in respect of the
      requirements of Regulation AB and (c) the parties shall comply with reasonable
      requests made by the Sponsor, the Master Servicer, the Depositor or the Trustee
      for delivery of additional or different information, to the extent such
      information is available or reasonably attainable within such time frame as

    PURCHASE
      AND TERMINATION

    OF
      THE
      TRUST FUND

     

    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 Trustee to make payments as set forth in Section 5.06 (relating to the
      Supplemental Prepayment Trust), 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 upon the occurrence
      of 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, (ii) the sale of the property held by the Trust Fund in accordance
      with Section 7.01(b) and (iii) the Latest Possible Maturity Date (each, a “Trust
      Fund Termination Event”); provided,
      however,
      that in
      no event shall the Trust Fund or Supplemental Prepayment Trust 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 or beyond the
      Latest Possible Maturity Date. Upon the occurrence of a Trust Fund Termination
      Event, each REMIC shall be terminated in a manner that shall qualify as a
“qualified liquidation” under the REMIC Provisions.

     

    (b) On
      any
      Distribution Date occurring after the date on which the aggregate Scheduled
      Principal Balance of the Mortgage Loans is less than 10% of the Cut-off Date
      Aggregate Principal Balance (the “Initial Optional Termination Date”), the
      Master Servicer or LTURI-holders, as applicable, may, upon written direction
      to
      the Trustee (delivered no later than 30 days prior to the anticipated sale
      date), cause (i) the Trustee to sell (or arrange for the sale of) in
      consultation with the Master Servicer or LTURI-holders, as applicable, the
      assets of the Trust Fund and (ii) the Trust Fund to adopt a plan of complete
      liquidation pursuant to Section 7.03(a)(i) hereof to sell all of its property.
      The property of the Trust Fund shall be sold at a price (the “Termination
      Price”) equal to the sum of: (i) 100% of the unpaid principal balance of each
      Mortgage Loan on the day of such purchase plus interest accrued thereon at
      the
      applicable Mortgage Rate with respect to any Mortgage Loan to the Due Date
      in
      the Due Period immediately preceding the related Distribution Date to the date
      of such repurchase, (ii) the fair market value of any REO Property and any
      other
      property held by any REMIC, such fair market value to be determined by an
      appraiser or appraisers appointed by the Master Servicer and reasonably
      acceptable to the Trustee (reduced, in the case of REO Property, by (1)
      reasonably anticipated disposition costs (as determined by the Master Servicer
      plus interest accrued thereon at the applicable Net Mortgage Rate to the date
      of
      purchases) and (2) any amount by which the fair market value as so reduced
      exceeds the outstanding principal balance of the related Mortgage Loan) and
      (iii) any unreimbursed Servicing Advances with respect to each Mortgage Loan.
      The Master Servicer, each Servicer, the Trustee and each Custodian shall be
      reimbursed from the Termination Price for any Mortgage Loan or related REO
      Property for any Advances made or other amounts advanced with respect to the
      Mortgage Loans that are reimbursable to any such entity under this Agreement,
      the applicable Servicing Agreement or the applicable Custodial Agreement,
      together with any accrued and unpaid compensation and any other amounts due
      to
      the Master Servicer or the Trustee hereunder or the Servicers or the
      Custodians.

    (c) On
      any
      Distribution Date occurring on or after the Initial Optional Termination Date,
      the Master Servicer, with the prior written consent of the Seller, which consent
      shall not be unreasonably withheld, has the option to purchase all of the Lower
      Tier REMIC 1 Uncertificated Regular Interests. Upon exercise of such option,
      the
      Lower Tier REMIC 1 Uncertificated Regular Interests shall be sold to the Master
      Servicer at a price (the “Lower Tier REMIC 1 Uncertificated Regular Interests
      Purchase Price”) equal to the sum of (i) 100% of the unpaid principal balance of
      each Mortgage Loan on the day of such purchase plus interest accrued thereon
      at
      the applicable Mortgage Rate with respect to any Mortgage Loan to the Due Date
      in the Collection Period immediately preceding the related Distribution Date
      to
      the date of such repurchase and (ii) the fair market value of any REO Property
      and any other property held by any REMIC, such fair market value to be
      determined by an independent appraiser or appraisers mutually agreed upon by
      the
      Master Servicer and the Trustee (reduced, in the case of REO Property, by (1)
      reasonably anticipated disposition costs and (2) any amount by which the fair
      market value as so reduced exceeds the outstanding principal balance of the
      related Mortgage Loan plus interest accrued thereon at the applicable Net
      Mortgage Rate to the date of such purchase). If the Master Servicer elects
      to
      exercise such option, each REMIC created pursuant to this Agreement (other
      than
      REMIC I) shall be terminated in such a manner so that the termination of each
      such REMIC shall qualify as a “qualified liquidation” under the REMIC Provisions
      and the Lower Tier REMIC 1 Uncertificated Regular Interests and the Class LT-R
      Certificates will evidence the entire beneficial interest in the property of
      the
      Trust Fund. Following a purchase of the Lower Tier REMIC 1 Uncertificated
      Regular Interests pursuant to this subsection, the Trust Fund (and REMIC I)
      will
      remain outstanding and final payment on the Certificates (other than the Class
      LT-R Certificates) will be made in accordance with Sections 7.03(a)(iii) and
      5.02. The Trust Fund will terminate upon the occurrence of a Trust Fund
      Termination Event, in accordance with Section 7.01(a).

      7.02. Procedure
      Upon Termination of Trust Fund.

    (a) Notice
      of
      any Trust Fund Termination Event and notice of the purchase of the Lower Tier
      REMIC 1 Uncertificated Regular Interests, specifying the Distribution Date
      upon
      which the final distribution to the Certificates (other than the Class LT-R
      Certificates, in the case of a purchase of the Lower Tier REMIC 1 Uncertificated
      Regular Interests) shall be made, shall be given promptly by the Trustee by
      first class mail to Certificateholders mailed no later than 5 Business Days
      after the Trustee has received notice from the Master Servicer of its election
      to cause (x) the sale of all of the property of the Trust Fund pursuant to
      Section 7.01(b), (y) the purchase of the Lower Tier REMIC 1 Uncertificated
      Regular Interests pursuant to Section 7.01(c) or (z) upon the final payment
      or
      other liquidation of the last Mortgage Loan or REO Property in the Trust Fund.
      In the case of a Trust Fund Termination Event, the Trustee shall also give
      notice to the Certificate Registrar (if the Trustee and the Certificate
      Registrar are not the same person) at the time notice is given to Holders of
      the
      Certificates.

     

    In
      the
      case of a Trust Fund Termination Event, such notice shall specify (A) the
      Distribution Date upon which final distribution on the Certificates or Lower
      Tier REMIC 1 Uncertificated Regular Interests 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.
      Upon
      any such Trust Fund Termination Event, the duties of the Certificate Registrar
      with respect to the Certificates or Lower Tier REMIC 1 Uncertificated Regular
      Interests shall terminate and the Trustee shall terminate or request the Master
      Servicer to terminate, the Collection Account it maintains, the Certificate
      Account and any other account or fund maintained with respect to the
      Certificates or Lower Tier REMIC 1 Uncertificated Regular Interests, subject
      to
      the Trustee’s obligation hereunder to hold all amounts payable to
      Certificateholders in trust without interest pending such payment. 

     

    In
      the
      case of a purchase of the Lower Tier REMIC 1 Uncertificated Regular Interests,
      such notice shall specify (A) the Distribution Date upon which final
      distribution on the Certificates (other than the Class LT-R Certificates) of
      all
      amounts required to be distributed to Certificateholders pursuant to Section
      5.02 (other than any distributions to the Class LT-R Certificates in respect
      of
      REMIC I) will be made upon presentation and surrender of the Certificates (other
      than the Class LT-R Certificates) at the Corporate Trust Office of the Trustee,
      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 (other than the Class LT-R Certificates) at the office or
      agency of the Trustee therein specified. Upon any such purchase of the Lower
      Tier REMIC 1 Uncertificated Regular Interests, the duties of the Certificate
      Registrar with respect to the Certificates other than the Class LT-R Certificate
      shall terminate but the Trustee shall not terminate or request the Master
      Servicer to terminate, the Collection Account it maintains, the Certificate
      Account and any other account or fund maintained with respect to the
      Certificates, subject to the Trustee’s obligation hereunder to hold all amounts
      payable to Certificateholders in trust without interest pending such payment.
      For all Distribution Dates following the Distribution Date on which the Master
      Servicer purchases the Lower Tier REMIC 1 Uncertificated Regular Interests,
      all
      amounts that would be distributed on the Certificates (other than the Class
      LT-R
      Certificate and exclusive of amounts payable from any fund held outside of
      REMIC
      I) absent such purchase shall be payable to the LTURI-holder.

     

    


    
      
        
          
          

        

        
          110

          
            

          

        

        
          
          

        

      

    

    


    (b) In
      the
      event that all of the applicable 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 such
      Certificateholders to surrender their Certificates for cancellation and receive
      the final distribution with respect thereto. If within one year after the second
      notice any such Certificates shall not have been surrendered for cancellation,
      the Trustee may take appropriate steps to contact such 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 such 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 Trust Fund
      Termination Event or any purchase of the Lower Tier REMIC I Uncertificated
      Regular Interests shall be reimbursed from proceeds received from the
      liquidation of the Trust Fund.

     

    Section
      7.03. Additional
      Requirements for any Trust Fund Termination Events or Purchase of the Lower
      Tier
      REMIC 1 Uncertificated Regular Interests. 

     

    (a) Any
      termination of the Trust Fund pursuant to Section 7.01(a) or any termination
      of
      a REMIC pursuant to Section 7.01(c) shall be effected in accordance with the
      following additional requirements, unless the Trustee receives (at the request
      of the party exercising the option to purchase all of the Mortgage Loans or
      Lower Tier REMIC 1 Uncertificated Regular Interests pursuant to Section 7.01(b)
      or Section 7.01(c), respectively) an Opinion of Counsel (at the expense of
      such
      requesting party), addressed to the Trustee to the effect that the failure
      to
      comply with the requirements of this Section 7.03 will not result in an Adverse
      REMIC Event:

     

    (i) Within
      89
      days prior to the time of the making of the final payment on the Certificates
      other than the Class LT-R Certificates, in the case of a purchase of the Lower
      Tier REMIC 1 Uncertificated Regular Interests, upon notification by the Master
      Servicer or an Affiliate of the Seller that it intends to exercise its option
      to
      cause the termination of the Trust Fund or purchase the Lower Tier REMIC 1
      Uncertificated Regular Interests, the Trustee shall adopt a plan of complete
      liquidation on behalf of each REMIC (other than REMIC I, in the case of a
      purchase of the Lower Tier REMIC 1 Uncertificated Regular Interests), meeting
      the requirements of a qualified liquidation under the REMIC Provisions;


     

    


    
      
        
          
          

        

        
          111

          
            

          

        

        
          
          

        

      

    

    


    (ii) Any
      sale
      of the assets of the Trust Fund or the Lower Tier REMIC 1 Uncertificated Regular
      Interests pursuant to Section 7.02 shall be a sale for cash and shall occur
      at
      or after the time of adoption of such a plan of complete liquidation and prior
      to the time of making of the final payment on the Certificates (other than
      the
      Class LT-R Certificates, in the case of a purchase of the Lower Tier REMIC
      1
      Uncertificated Regular Interests);

     

    (iii) On
      the
      date specified for final payment of the Certificates (other than the Class
      LT-R
      Certificates, in the case of a purchase of the Lower Tier REMIC 1 Uncertificated
      Regular Interests), the Trustee shall make final distributions of principal
      and
      interest on such Certificates in accordance with Section 5.02. In the case
      of a
      Trust Fund Termination Event, and, after payment of, or provision for any
      outstanding expenses, the Trustee shall distribute or credit, or cause to be
      distributed or credited, to the Holders of the Residual Certificates all cash
      on
      hand after such final payment (other than cash retained to meet claims), and
      the
      Trust Fund (and each REMIC) shall terminate at that time; and

     

    (iv) In
      no
      event may the final payment on the Certificates or the final distribution or
      credit to the Holders of the Residual Certificates in respect of the residual
      interest in any liquidated REMIC be made after the 89th day from the date on
      which the plan of complete liquidation for such REMIC is adopted.

     

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

     

    (c) In
      connection with the termination of the Trust Fund or a Section 7.01(c) Purchase
      Event, the Trustee may request an Opinion of Counsel addressed to the Trustee
      (at the expense of the Depositor) to the effect that all of the requirements
      of
      a qualified liquidation under the REMIC Provisions have been met.

     

    Section
      7.04. Charged-off
      Loans and Released Mortgage Loans.

     

    Notwithstanding
      anything to the contrary contained in this Agreement, each Charged-off Loan
      that
      becomes a Released Mortgage Loan shall be released from the Trust Fund as soon
      as practicable after becoming a Released Mortgage Loan and shall no longer
      be an
      asset of any REMIC. Each Released Mortgage Loan shall be transferred to the
      Released Mortgage Transferee, without recourse. The Trustee, upon receipt of
      certification from the Master Servicer that a Charged-off Loan has become a
      Released Mortgage Loan, shall execute such instruments of transfer, assignment
      or release, in each case, without recourse, as shall be provided by the Master
      Servicer and necessary to transfer such Released Mortgage Loan. Thereafter
      (i)
      the Released Mortgage Transferee shall be entitled to any amounts subsequently
      received in respect of any such Released Mortgage Loans, (ii) the Released
      Mortgage Transferee may designate any Servicer to service any such Released
      Mortgage Loan and (iii) the Released Mortgage Transferee may sell any such
      Released Mortgage Loan to a third party. For purposes of compliance with the
      REMIC Provisions, any such Released Mortgage Loan transferred to the Released
      Mortgage Transferee pursuant to this Section 7.04 and having any value as of
      the
      date of such transfer shall be treated as having been transferred by the related
      REMIC as additional compensation for services provided to such
      REMIC.

    RIGHTS
      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) of Certificates of each Class shall have made written request upon
      the
      Trustee to institute such action, suit or proceeding in its own name as Trustee
      hereunder and shall have offered to the Trustee such reasonable indemnity as
      it
      may require against the cost, expenses and liabilities to be incurred therein
      or
      thereby, and the Trustee, for sixty days after its receipt of such notice,
      request and offer of indemnity, shall have neglected or refused to institute
      any
      such action, suit or proceeding and no direction inconsistent with such written
      request has been given such Trustee during such sixty-day period by such
      Certificateholders; it being understood and intended, and being expressly
      covenanted by each Certificateholder with every other Certificateholder and
      the
      Trustee, that no one or more Holders of Certificates shall have any right in
      any
      manner whatever by virtue or by availing of any provision of this Agreement
      to
      affect, disturb or prejudice the rights of the Holders of any other of such
      Certificates, or to obtain or seek to obtain priority over or preference to
      any
      other such Holder, or to enforce any right under this Agreement, except in
      the
      manner herein provided and for the benefit of all Certificateholders. For the
      protection and enforcement of the provisions of this Section, each and every
      Certificateholder and the Trustee shall be entitled to such relief as can be
      given either at law or in equity.

    Section
      8.02. Access
      to List of Holders. 

     

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

     

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

     

    (c) Every
      Holder or Certificate Owner, if the Holder is a Clearing Agency, by receiving
      and holding a Certificate, agrees with the Depositor, the Master Servicer,
      the
      Certificate Registrar and the Trustee that 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
      the
      Master Servicer, if made in the manner provided in this Section. Each of the
      Trustee and the Master Servicer shall promptly notify the others of receipt
      of
      any such instrument by it, and shall promptly forward a copy of such instrument
      to the others.

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

     

    (c) The
      ownership of Certificates or Lower Tier REMIC I Uncertificated Regular Interests
      (whether or not such Certificates or Lower Tier REMIC I Uncertificated Regular
      Interests 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, or
      the
      Depositor shall be affected by any notice to the contrary.

     

    (d) Any
      request, demand, authorization, direction, notice, consent, waiver or other
      action by the Holder of any Certificate or Lower Tier REMIC I Uncertificated
      Regular Interests shall bind every future Holder of the same Certificate and
      the
      Holder of every Certificate or Lower Tier REMIC I Uncertificated Regular
      Interests 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 or Lower Tier REMIC
      I
      Uncertificated Regular Interests.

    Section
      9.01. Duties
      of the Master Servicer. 

     

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

     

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

     

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

      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

    (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.

      Servicer’s Financial Statements and Related Information. 

     

    For
      each

      Rating Agency, the Trustee and the Depositor a copy of the annual audited
      financial statements of its corporate parent on or prior to March 31st of each

      accepted accounting principles, certified by a nationally recognized firm of

    (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,
      the Trustee 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, 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 formed hereby 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 applicable Servicer, as the case may be,
      believes it appropriate in its best judgment and in accordance with Accepted
      Servicing Practices and the applicable Servicing Agreement, to execute and
      deliver, on behalf of itself and the Certificateholders, the Trustee or any
      of
      them, any and all instruments of satisfaction or cancellation, or of partial
      or
      full release or discharge and all other comparable instruments, with respect
      to
      the Mortgage Loans and with respect to the Mortgaged Properties. The Trustee
      shall execute, upon request, any powers of attorney furnished to it (and
      reasonably acceptable to it) by the Master Servicer empowering the Master
      Servicer or any 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 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 any 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. The Master
      Servicer shall indemnify the Trustee for any and all costs, liabilities and
      expenses incurred by the Trustee in connection with the negligent or willful
      misuse of such powers of attorney by the Master Servicer.

    (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 or any prepayment charge or penalty interest in connection with
      the prepayment of a Mortgage Loan, and, except as set forth below (ii) extend
      the due dates for payments due on a Mortgage Note for a period not greater
      than
      120 days; provided,
      however,
      that
      the maturity of any Mortgage Loan shall not be extended past the date on which
      the final payment is due on the latest maturing Mortgage Loan as of the Cut-off
      Date. In the event of any extension described in clause (ii) above, the Master
      Servicer shall make or cause to be made Advances on the related Mortgage Loan
      in
      accordance with the provisions of Section 5.04 on the basis of the amortization
      schedule of such Mortgage Loan without modification thereof by reason of such
      extension. Notwithstanding
      anything to the contrary in this Agreement, the Master Servicer shall not make
      or knowingly permit any modification, waiver or amendment of any material term
      of any Mortgage Loan unless: (1) such Mortgage Loan is in default or default
      by
      the related Mortgagor is, in the reasonable judgment of the Master Servicer
      or
      the applicable
      Servicer, reasonably foreseeable, (2) in the case of a waiver of a Prepayment
      Penalty Amount if (a) such Mortgage Loan is in default or default by the related
      Mortgagor is reasonably foreseeable, and such waiver would maximize recovery
      of
      total proceeds taking into account the value of such Prepayment Penalty Amount
      and the related Mortgage Loan or (b) if the prepayment is not the result of
      a
      refinance by a Servicer or any of its affiliates and (i) such Mortgage Loan
      is
      in default or default by the related Mortgagor is, in the reasonable judgment
      of
      the Master Servicer or the
      applicable
      Servicer, reasonably foreseeable, and such waiver would maximize recovery of
      total proceeds taking into account the value of such Prepayment Penalty Amount
      and the related Mortgage Loan or (ii) the collection of the Prepayment Penalty
      Amount would be in violation of applicable laws or (iii) the collection of
      such
      Prepayment Penalty Amount would be considered “predatory” pursuant to written
      guidance published or issued by any applicable federal, state or local
      regulatory authority acting in its official capacity and having jurisdiction
      over such matters, and (3) the Master Servicer shall have provided or caused
      to
      be provided to the Trustee an Opinion of Counsel(which opinion shall, if
      provided by the Master Servicer, be an expense reimbursed from the Collection
      Account pursuant to Section 4.02(v)) in writing to the effect that such
      modification, waiver or amendment would not cause an Adverse REMIC Event;
provided,
      in no event shall an Opinion of Counsel be required for the waiver of a
      Prepayment Penalty Amount under clause (2) above. Notwithstanding
      anything to the contrary, the Master Servicer shall not without the Trustee’s
      written consent: (i) initiate any action, suit or proceeding solely under the
      Trustee’s name without indicating the Master Servicer’s representative capacity
      or (ii) take any action with the intent to cause, and which actually does cause,
      the Trustee to be registered to do business in any state.

    Section
      9.05. Servicing
      Agreements Between the Master Servicer and Servicers; Enforcement of Servicers’
Obligations. 

     

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

     

    (b) The
      Master Servicer shall not be required to (i) take any action with respect to
      the
      servicing of any Mortgage Loan that the 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 such Servicer to take such action or refrain from taking such
      action; in both cases notwithstanding any provision of this Agreement that
      requires the Master Servicer to take such action or cause a 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 each 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 the 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 or (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,
      (iii) from the Collection Account.

    (d) The
      Master Servicer shall be entitled to rely conclusively on any certifications
      or
      other information provided by each Servicer under the terms of each Servicing
      Agreement in its preparation of any certifications, notifications, filings
      or
      reports to be made 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, extraordinary costs, and not ordinary
      or
      routine costs shall be recoverable by the Master Servicer pursuant to Section
      4.02(v).

      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 Agreement 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 such Servicer in the performance
      by a Servicer of its obligations under the related Servicing
      Agreement.

     

    Section
      9.09. No
      Contractual Relationship Between Servicers 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
      related Seller and the Master Servicer, and except to the extent expressly
      provided therein 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.

     

    


    
      
        
          
          

        

        
          121

          
            

          

        

        
          
          

        

      

    

    


    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 issuance of any notice of termination
      pursuant to Section 6.14 or Section 9.28, as applicable, the Trustee shall,
      in
      accordance with Section 6.14, 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 (or its designee) 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
      to
      the extent provided in this Agreement, 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.

     

    


    
      
        
          
          

        

        
          122

          
            

          

        

        
          
          

        

      

    

    


    (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 collectibility 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 the such Servicer as additional servicing
      compensation.

     

    Section
      9.12. Release
      of Mortgage Files.

     

    (a) Upon
      (i)
      becoming aware of the payment in full of any Mortgage Loan or, (ii) the receipt
      by the applicable Servicer of a notification that payment in full has been
      or
      will be escrowed in a manner customary for such purposes, 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 a 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 applicable
      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 the 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 applicable
      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 applicable Custodian, as applicable, when the need therefor by the
      Master Servicer or applicable Servicer no longer exists unless (i) the Mortgage
      Loan shall be liquidated, in which case, upon receipt of a certificate of a
      Servicing Officer similar to that herein above specified, the trust receipt
      shall be released by the Trustee or the applicable 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.

     

    


    
      
        
          
          

        

        
          123

          
            

          

        

        
          
          

        

      

    

    


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

     

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

     

    


    
      
        
          
          

        

        
          124

          
            

          

        

        
          
          

        

      

    

    


    (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 either Seller
      to the Depositor not to constitute a sale, the Trustee shall have a security
      interest in either Mortgage Loans and in all Mortgage Files representing such
      Mortgage Loans and in all funds 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 such 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 a 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 a Servicer
      to,
      create, incur or subject any Mortgage Loans, or any funds that are deposited
      in
      any custodial account, Escrow Account or the Collection Account, or any funds
      that otherwise are or may become due or payable to the Trustee, to any claim,
      lien, security interest, judgment, levy, writ of attachment or other
      encumbrance, nor assert by legal action or otherwise any claim or right of
      setoff against any Mortgage Loan or any funds collected on, or in connection
      with, a Mortgage Loan.

     

    Section
      9.14. Representations

          126

      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 either the Depositor, the Master Servicer 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) through (f) 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) through (f) hereof. It is understood and agreed
      that the enforcement of the obligation of the Depositor set forth in this
      Section to indemnify the Master Servicer as provided in this Section constitutes
      the sole remedy of the Master Servicer respecting a breach by the Depositor
      of
      the representations and warranties in Sections 2.03(a) through (f)
      hereof.

     

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

      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

    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 a Servicer’s normal servicing procedures and Accepted
      Servicing Practices) shall be deposited into the Collection Account, subject
      to
      withdrawal pursuant to Section 4.02. Any cost incurred by the Master Servicer
      or
      any Servicer in maintaining any such insurance if the Mortgagor defaults in
      its
      obligation to do so shall be added to the amount owing under the Mortgage Loan
      where the terms of the Mortgage Loan so permit; provided,
      however,
      that
      the addition of any such cost shall not be taken into account for purposes
      of
      calculating the distributions to be made to Certificateholders and shall be
      recoverable by the Master Servicer or such Servicer pursuant to Section
      4.02(v).

     

    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 a
      Servicer’s normal servicing procedures need not be so deposited (or
      remitted).

    Section
      9.18. Maintenance
      of the Primary Mortgage Insurance Policies. 

     

    (a) The
      Master Servicer shall not take, or knowingly permit any Servicer (consistent
      with the applicable Servicing Agreement) to take, any action that would result
      in 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 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 pursuant to the Custodial Agreement),
      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 any Custodian,
      as directed by the Trustee) shall also retain possession and custody of each
      Mortgage File in accordance with and subject to the terms and conditions of
      this
      Agreement. The Master Servicer shall promptly deliver or cause to be delivered
      to the Trustee (or the applicable Custodian pursuant to the Custodial
      Agreement), 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. 

     

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

    Section
      9.21. Compensation
      to the Master Servicer. 

     

    The
      Master Servicer shall be entitled to withdraw from the Collection Account,
      the
      Master Servicing Fee to the extent permitted by Section 4.02(vi). Servicing
      compensation in the form of assumption fees, if any, late payment charges,
      as
      collected, if any, or otherwise shall be retained by the Master Servicer (or
      the
      applicable Servicer) and shall not be deposited in the Collection Account.
      If
      the Master Servicer does not retain or withdraw the Master Servicing Fee from
      the Collection Account as provided herein, the Master Servicer shall be entitled
      to direct the Trustee to pay the Master Servicing Fee to such Master Servicer
      by
      withdrawal from the Certificate Account. 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.

     

    


    
      
        
          
          

        

        
          130

          
            

          

        

        
          
          

        

      

    

    


    (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 be remitted by wire transfer
      in
      immediately available funds to the Trustee for deposit into the Certificate
      Account on the next succeeding Master Servicer Remittance Date.

     

    Section
      9.23. Notices
      to the Depositor and the Trustee 

     

    (a) The
      Master Servicer shall promptly notify the Trustee, the Sponsor and the Depositor
      (i) of any legal proceedings pending against the Master Servicer of the type
      described in Item 1117 (§ 229.1117) of Regulation AB and (ii) if the Master
      Servicer shall become (but only to the extent not previously disclosed) at
      any
      time an affiliate of any of the parties listed on Exhibit I to this Agreement.
      On or before March 1st
      of each
      year, the Depositor shall distribute the information in Exhibit I to the Master
      Servicer.

     

    (b) Not
      later
      than three 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.

    Section
      9.24. Reports

      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
      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
      with other electronic loan level reporting supplied by the Master Servicer
      in

      the Mortgage Loans as of the related Determination Date (including information
      on any Net Prepayment Interest Shortfalls), 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

      of Compliance and Attestation Reports.

      thereof, and (D) a statement that a registered public accounting firm has issued
      an attestation report on such party’s assessment of compliance with the Relevant
      Servicing Criteria as of and for such period. If the Trustee and the Paying
      Agent are the same party, the Relevant Servicing Criteria of the Paying Agent
      shall be included in the Trustee’s report.

    (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, 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.

     

    (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 Q 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
      Q
      and on any similar exhibit set forth in the Servicing Agreement and Custodial
      Agreement 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) By
      March
      15 of each year, commencing in March 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, the Paying
      Agent and the Trustee, as the case may be) that is a member of the American
      Institute of Certified Public Accountants to furnish a report to the Sponsor,
      the Depositor, the Master Servicer and the Trustee, to the effect that (A)
      it
      has obtained a representation regarding certain matters from the management
      of
      such party, which includes an assertion that such party has complied with the
      Relevant Servicing Criteria, and (B) on the basis of an examination conducted
      by
      such firm in accordance with standards for attestation engagements issued or
      adopted by the PCAOB, it is expressing an opinion as to whether such party’s
      compliance with the Relevant Servicing Criteria was fairly stated in all
      material respects, or it cannot express an overall opinion regarding such
      party’s assessment of compliance with the Relevant Servicing Criteria. 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.

     

    


    
      
        
          
          

        

        
          133

          
            

          

        

        
          
          

        

      

    

    


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

     

    (c) The
      Trustee's, 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. Notwithstanding the foregoing after the occurrence of such event and
      provided the Depositor is not otherwise provided with such reports or copies
      of
      such reports, the Trustee and Paying Agent shall be obligated to provide a
      copy
      of such reports by March 15 of each year to the Depositor.

     

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

     

    (a) 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.

     

    Copies
      of
      such statements shall be provided to any Certificateholder upon request, by
      the
      Master Servicer or by the Trustee at the Master Servicer’s expense if the Master
      Servicer failed 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) The
      Master Servicer shall give prompt written notice to the Trustee, the Sponsor
      and
      the Depositor of the appointment of any Subcontractor by it and a written
      description (in form and substance satisfactory to the Trustee, the Sponsor
      and
      the Depositor) of the role and function of each Subcontractor utilized by the
      Master Servicer, 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.

    Section
      9.27. Merger
      or Consolidation. 

     

    Any
      Person into which the Master Servicer may be merged or consolidated, or any
      Person resulting from any merger, conversion, other change in form or
      consolidation to which the Master Servicer shall be a party, or any Person
      succeeding to the business of the Master Servicer, shall be the successor to
      the
      Master Servicer hereunder, without the execution or filing of any paper or
      any
      further act on the part of any of the parties hereto, anything herein to the
      contrary notwithstanding; provided,
      however,
      that
      the successor or resulting Person to the Master Servicer shall be a Person
      that
      shall be qualified and approved to service mortgage loans for FNMA or FHLMC
      and
      shall have a net worth of not less than $15,000,000.

     

    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
      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. No such resignation shall become effective until
      the
      Trustee shall have assumed, or a successor master servicer acceptable to the
      Trustee shall have been appointed by the Trustee and until such successor shall
      have assumed, the Master Servicer’s responsibilities and obligations under this
      Agreement. Notice of such resignation shall be given promptly by the Master
      Servicer and the Depositor to the Trustee.

     

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

     

    Except
      as
      expressly provided herein, the Master Servicer shall not assign or transfer
      any
      of its rights, benefits or privileges hereunder to any other Person, or delegate
      to or subcontract with, or authorize or appoint any Subservicer, Subcontractor
      or 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.

    The
      Master Servicer shall not permit a Subservicer to perform any master servicing
      responsibilities hereunder with respect to the Mortgage Loans unless that
      Subservicer first agrees in writing with such Master Servicer to deliver an
      assessment of compliance and an accountant’s attestation in such manner and at
      such times in compliance with Sections 9.25(a)(ii) and (b)(ii) of this
      Agreement.

     

    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 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 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 and the
      Depositor and any director, officer, employee or agent of any of them shall
      be
      entitled to indemnification by the Trust Fund and will be held harmless against
      any loss, liability or expense incurred in connection with any legal action
      relating to this Agreement or the Certificates other than any loss, liability
      or
      expense incurred by reason of willful misfeasance, bad faith or negligence
      in
      the performance of his or its duties hereunder or by reason of reckless
      disregard of his or its obligations and duties hereunder. The Master Servicer,
      the Seller and the Depositor and any director, officer, employee or agent of
      any
      of them may rely in good faith on any document of any kind prima facie properly
      executed and submitted by any Person respecting any matters arising hereunder.
      The Master Servicer shall be under no obligation to appear in, prosecute or
      defend any legal action that is not incidental to its duties to master service
      the Mortgage Loans in accordance with this Agreement and that in its opinion
      may
      involve it in any expenses or liability; provided,
      however,
      that the
      Master Servicer may in its sole discretion undertake any such action that it
      may
      deem necessary or desirable in respect to this Agreement and the rights and
      duties of the parties hereto and the interests of the Certificateholders
      hereunder. In such event, the legal expenses and costs of such action and any
      liability resulting therefrom shall be expenses, costs and liabilities of the
      Trust Fund and the Master Servicer shall be entitled to be reimbursed therefor
      out of the Collection Account it maintains as provided by Section
      4.02.

    Section
      9.31. Indemnification;
      Third-Party Claims. 

     

    The
      Master Servicer agrees to indemnify the Depositor, the Sponsor and the Trustee,
      and their respective officers, directors, agents and affiliates, and hold each
      of them harmless against any and all claims, losses, penalties, fines,
      forfeitures, reasonable legal fees and related costs, judgments, and any other
      costs, liability, fees and expenses that the Depositor, the Sponsor or the
      Trustee may sustain as a result of (a) any material breach by the Master
      Servicer of any if its obligations hereunder, including particularly its
      obligations to provide any reports under Section 9.25(a), Section 9.25(b),
      Section 9.26 or any information, data or materials required to be included
      in
      any Exchange Act report, (b) any material misstatement or omission in any
      information, data or materials provided by the Master Servicer, or (c) the
      negligence, bad faith or willful misconduct of the Master Servicer in connection
      with its performance hereunder, provided,
      however,
      that in
      no event shall the Master Servicer be liable for any special, consequential,
      indirect or punitive damages pursuant to this Section 9.31, even if advised
      of
      the possibility of such damages. The Depositor, the Sponsor and the Trustee
      shall immediately notify the Master Servicer if a claim is made by a third
      party
      with respect to this Agreement or the Mortgage Loans entitling the Depositor,
      the Sponsor or the Trustee to indemnification hereunder, whereupon the Master
      Servicer shall assume the defense of any such claim and pay all expenses in
      connection therewith, including counsel fees, and promptly pay, discharge and
      satisfy any judgment or decree which may be entered against it or them in
      respect of such claim. Notwithstanding anything to the contrary contained
      herein, the Master Servicer shall not settle any claim involving any of the
      other parties hereto without such party’s prior written consent unless such
      settlement involves a complete and absolute release of such party from any
      and
      all liability in connection with such claim. This indemnification shall survive
      the termination of this Agreement or the termination of the Master Servicer
      as a
      party to this Agreement.

     

    Section
      9.32. Special
      Servicing of Delinquent Mortgage Loans. 

     

    If
      permitted under the terms of a Servicing Agreement, the Seller may appoint,
      pursuant to the terms of such Servicing Agreement and with the written consent
      of the Depositor, the Master Servicer and the Trustee, a special Servicer (the
      “Special Servicer”) to special service any Distressed Mortgage Loans. Any
      applicable termination fee related to the termination of a Servicer and the
      appointment of any Special Servicer shall be paid by the Mortgage Loan Seller
      from its own funds, without right of reimbursement from the Trust Fund. Any
      fees
      paid to any such Special Servicer shall not exceed the Servicing Fee
      Rate.

    REMIC
      ADMINISTRATION

     

    Section
      10.01. REMIC
      Administration. 

     

    (a) As
      set
      forth in the Preliminary Statement hereto, the Trustee shall elect REMIC status
      in accordance with the REMIC Provisions with respect to each of the REMICs.
      The
      Trustee shall make such elections on Forms 1066 or other appropriate federal
      tax
      or information return for the taxable year ending on the last day of the
      calendar year in which the Certificates are issued. For the purposes of such
      elections, each of the Interests in REMIC I, other than the Class LT-R
      Certificate, is hereby designated as a regular interest in REMIC I; each of
      the
      interests in REMIC II, other than the Class R-2 Interest, is hereby designated
      as a regular interest in REMIC II; and each Underlying REMIC Certificate and
      each Certificate (other than with respect to any Class P Component thereof
      or
      the Exchange Certificates, the Exchangeable Certificates, and the Class LT-R
      and
      Class R Certificates) are hereby designated as regular interests in REMIC III.
      In addition, the Class R-2 Interest is hereby designated as the sole residual
      interest in REMIC II, and the Class R Certificate evidences ownership of the
      Class R-2 Interest, and is also hereby designated as the sole residual interest
      in REMIC III.

     

    (b) The
      Closing Date is hereby designated as the “Startup Day” of each REMIC within the
      meaning of section 86OG(a)(9) of the Code. The latest possible maturity date
      for
      purposes of Treasury Regulation 1.86OG-1(a)(4) will be the Latest Possible
      Maturity Date.

     

    (c) The
      Trustee shall pay any and all tax related expenses (not including taxes) of
      each
      REMIC, including but not limited to any professional fees or expenses related
      to
      audits or any administrative or judicial proceedings with respect to such REMIC
      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 of expenses to the extent
      provided in clause (i) above from the Certificate Account, provided,
      however,
      the
      Trustee shall not be entitled to reimbursement for expenses incurred in
      connection with the preparation of tax returns and Form SS-4 as required by
      Section 6.20 and this Section 10.01.

     

    (d) The
      Trustee shall prepare, sign and file all of each REMIC’s federal and applicable
      state tax and information returns as such REMIC’s direct representative. As used
      in the previous sentence, “applicable state tax and information returns” shall
      mean such returns as may be required by the laws of any state, the applicability
      of which to the Trust Fund shall have been confirmed to the Trustee in writing
      either (i) by the delivery to the Trustee of an Opinion of Counsel to such
      effect, or (ii) by delivery to the Trustee of a written notification to such
      effect by the taxing authority of such state. 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. The Trustee shall be entitled to additional
      compensation from such person for the cost of providing such
      information.

    (e) The
      Trustee shall perform on behalf of each REMIC all reporting and other tax
      compliance duties that are the responsibility of such REMIC 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 the REMIC Provisions.

     

    If,
      after
      the Closing Date, as a result of any changes to the Code, the REMIC Provisions,
      or other compliance guidance issued by the Internal Revenue Service or any
      state
      or local taxing authority, the Trustee shall have additional duties or
      obligations pursuant to this subsection (e), the Trustee shall be entitled
      to
      receive reasonable compensation for the performance of its duties under this
      subsection (e); provided,
      however,
      that
      such compensation shall not exceed $5,000 per year.

     

    (f) The
      Trustee, the Master Servicer and the Holders of Certificates shall take any
      action within their respective control and scope of its duties or cause each
      REMIC 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. None of the Trustee, the Master
      Servicer or the Holder of any Residual Certificate shall take any action within
      their respective control, cause any REMIC to take any action or fail to take
      (or
      fail to cause to be taken) any action within its control and in the scope of
      its
      duties that, under the REMIC Provisions, if taken or not taken, as the case
      may
      be, could (i) endanger the status of any REMIC as a REMIC or (ii) result in
      the imposition of a tax upon any 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 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 REMIC or the assets therein, or causing any REMIC
      to
      take any action, which is not expressly permitted under the terms of this
      Agreement any Holder of a Residual Certificate will consult with the Trustee
      and
      the Master Servicer, or their respective designees, in writing, with respect
      to
      whether such action could cause an Adverse REMIC Event to occur with respect
      to
      any REMIC, and no such Person shall take any such action or cause any REMIC
      to
      take any such action as to which the Trustee or the Master Servicer has advised
      it in writing that an Adverse REMIC Event could occur.

     

    


    
      
        
          
          

        

        
          139

          
            

          

        

        
          
          

        

      

    

    


    (g) Each
      Holder of a Residual Certificate shall pay when due any and all taxes imposed
      on
      the related REMIC by federal or state governmental authorities. To the extent
      it
      has actual knowledge that such taxes were 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 Certificate Account, and shall reduce amounts otherwise
      payable to holders of regular interests in such REMIC, as the case may
      be.

     

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

     

    (i) No
      additional contributions of assets shall be made to any REMIC, except as
      expressly provided in this Agreement with respect to eligible substitute
      mortgage loans.

     

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

     

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

     

    Section
      10.02. Prohibited
      Transactions and Activities. 

     

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

     

    


    
      
        
          
          

        

        
          140

          
            

          

        

        
          
          

        

      

    

    


    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 Holder of the 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, a Servicer, the Depositor, or the Holder
      of
      such Residual Certificate, as applicable, or for any such Losses resulting
      from
      misinformation provided by the Holder of such Residual Certificate on which
      the
      Trustee has relied. The foregoing shall not be deemed to limit or restrict
      the
      rights and remedies of the Holder of such Residual Certificate now or hereafter
      existing at law or in equity. Notwithstanding the foregoing, however, in no
      event shall the Trustee have any liability (1) for any action or omission that
      is taken in accordance with and in compliance with the express terms of, or
      which is expressly permitted by the terms of, this Agreement, (2) for any Losses
      other than arising out of a negligent performance by the Trustee 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) permit any Servicer to, rent, lease, or
      otherwise earn income 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
      any REMIC by the REO Property would not result in the imposition of a tax upon
      such REMIC.

     

    (b) The
      Master Servicer shall make, or shall cause the applicable Servicer to make,
      reasonable efforts to sell any REO Property for its fair market value. In any
      event, however, the Master Servicer shall, or shall cause the applicable
      Servicer to, dispose of any REO Property within three years from the end of
      the
      calendar year of its acquisition by the Trust Fund unless the Master Servicer
      has received a grant of extension from the Internal Revenue Service to the
      effect that, under the REMIC Provisions and any relevant proposed legislation
      and under applicable state law, the 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
      Trust Fund, 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 Trust Fund hereunder, or the applicable Servicer
      is
      unable to sell the REO Property within 33 months after its acquisition by the
      Trust Fund or if an extension has been received and the Master Servicer acting
      on behalf of the Trust Fund 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) On
      or
      prior to a Section 7.01(c) Purchase Event, this Agreement may be amended from
      time to time by the Depositor, the Master Servicer and the Trustee, without
      notice to or the consent of any of the Holders, (i) to cure any ambiguity,
      (ii)
      to cause the provisions herein to conform to or be consistent with or in
      furtherance of the statements made with respect to the Certificates, the Trust
      Fund or this Agreement in any Offering Document; or to correct or supplement
      any
      provision herein which may be inconsistent with any other provisions herein,
      (iii) to make any other provisions with respect to matters or questions arising
      under this Agreement or with the provisions of any Servicing Agreement (iv)
      to
      add, delete, or amend any provisions to the extent necessary or desirable to
      comply with any requirements imposed by the Code and the REMIC Provisions.
      No
      such amendment effected pursuant to the preceding sentence shall, as evidenced
      by an Opinion of Counsel, adversely affect the status of any REMIC created
      pursuant to this Agreement, nor shall such amendment effected pursuant to clause
      (iii) of such sentence adversely affect in any material respect the interests
      of
      any Holder. Prior to entering into any amendment without the consent of Holders
      pursuant to this paragraph, the Trustee may require an Opinion of Counsel (at
      the expense of the party requesting such amendment) to the effect that such
      amendment is permitted under this paragraph. Any such amendment shall be deemed
      not to adversely affect in any material respect any Holder if the Trustee
      receives written confirmation from each Rating Agency that such amendment will
      not cause such Rating Agency to reduce, qualify or withdraw the then current
      rating assigned to the Certificates (and any Opinion of Counsel requested by
      the
      Trustee in connection with any such amendment may rely expressly on such
      confirmation as the basis therefor). 

     

    


    
      
        
          
          

        

        
          142

          
            

          

        

        
          
          

        

      

    

    


    (b) On
      or
      prior to a Section 7.01(c) Purchase Event, this Agreement may also be amended
      from time to time by the Depositor, the Master Servicer and the Trustee with
      the
      consent of the Holders of not less than 66 2/3% of the Class Principal Amount
      (or Class Notional Amount or Percentage Interest) of each Class of Certificates
      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,
      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 Class Notional
      Amount or Percentage Interest) of Certificates of each Class, the Holders of
      which are required to consent to any such amendment without the consent of
      the
      Holders of 100% of the Class Principal Amount (or Class Notional Amount) of
      each
      Class of Certificates affected thereby. For purposes of this paragraph,
      references to “Holder” or “Holders” shall be deemed to include, in the case of
      any Class of Book-Entry Certificates, the related Certificate
      Owners.

     

    (c) After
      a
      Section 7.01(c) Purchase Event but on or prior to a Trust Fund Termination
      Event, this Agreement may be amended from time to time by the Depositor, the
      Master Servicer, the
      Trustee,
      the LTURI holder and the Trustee. Prior to entering into any amendment without
      the consent of Holders pursuant to this paragraph, the Trustee
      shall be provided with an Opinion of Counsel addressed to the Trustee
      (at the expense of the party requesting such amendment) to the effect that
      such
      amendment is permitted under this Section and will not result in an Adverse
      REMIC Event.

     

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

     

    (e) 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.

     

    


    
      
        
          
          

        

        
          143

          
            

          

        

        
          
          

        

      

    

    


    (f) 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 Section 11.03(a) or Section
      11.03(b) 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 as evidenced by an Officer’s Certificate of the
      Depositor.

     

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

     

    (h) Prior
      to
      the execution of any amendment to this Agreement, the Trustee shall be entitled
      to receive and rely upon an Opinion of Counsel addressed to it stating that
      the
      execution of such amendment is authorized or permitted by this Agreement. The
      Trustee may, but shall not be obligated to, enter into any such amendment which
      affects the Trustee’s own rights, duties or immunities under this
      Agreement.

     

    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),
      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 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 or Form 10-K filed
      with the Securities and Exchange Commission pursuant to Section 6.20(c) and
      (ii)
      a copy of any other document incorporated by reference in 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 documents shall be

    Section

      of Servicing. 

     

    The
      Seller agrees that it shall provide written notice to the Trustee and the Master
      Servicer thirty days prior to any transfer or assignment by the Seller of its
      rights under any Servicing Agreement or of the servicing thereunder or
      delegation of its rights or duties thereunder or any portion thereof to any
      Person other than the initial Servicer under any Servicing Agreement;
provided,
      that
      (i) 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 or (ii) LBH or LBB shall be
      required to provide notice of any transfer of servicing rights by either of
      them
      to the other. In addition, the ability of the Seller to transfer or assign
      its
      rights and delegate its duties under any Servicing Agreement (other than a
      transfer of servicing rights between LBH and LBB) or to transfer the servicing
      thereunder to a successor servicer shall be subject to the following
      conditions:

     

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

     

    (ii) Such
      successor servicer must satisfy a 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;

     

    (iii) 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 a Servicer under the applicable
      Servicing Agreement or, (i) in the case of a transfer of servicing to a party
      that is already a Servicer pursuant to this Agreement, an agreement to add
      the
      related Mortgage Loans to each Servicing Agreement already in effect with each
      Servicer and (ii) in the case of a transfer of servicing to a Special Servicer
      pursuant to Section 9.32 herein, a special servicing agreement in the form
      of
      that attached to each Servicing Agreement;

    (iv) If
      the
      successor servicer is not a Servicer of Mortgage Loans at the time of 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;
      and

     

    (v) 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 Servicer Remittance
      Date
      but before the next succeeding Master Servicer Remittance 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.

      Certificate by the Investor will not result in any non-exempt prohibited

      subject the Trustee, the Certificate Registrar, the Depositor or the Master
      Servicer to any obligation in addition to those undertaken by such entities
      in
      the Trust Agreement, which opinion of counsel shall not be an expense of the
      Trust Fund or any of the above parties.

     

    5. That
      the
      Purchaser hereby acknowledges that under the terms of the Trust Agreement (the

    6. That

    7. That
      the
      Purchaser does not have the intention to impede the assessment or collection
      of

      to
      such Residual Certificate, and that the Purchaser has provided financial
      statements or other financial information requested by the transferor in

      taxes.

     

    8. That
      the
      Purchaser will not transfer a Residual Certificate to any person or entity

      a written statement substantially in the form of Exhibit G to the

    9. That

      Purchaser understands that, as the holder of a Residual Certificate, the

      Certificate as they become due.

     

    10. That
      the
      Purchaser (i) is a U.S. Person or (ii) is a Non-U.S. Person that holds a

      of Foreign Person’s Claim for exception From Withholding on Income Effectively
      Connected with the Conduct of a Trade or Business in the United States) or
      successor form at the time and in the manner required by the Code. “Non-U.S.

      States; (ii) a corporation (or entity treated as a corporation for tax purposes)
      created or organized in the United States or under the laws of the United States
      or of any state thereof, including, for this purpose, the District of Columbia;

      provided otherwise by future Treasury regulations); (iv) an estate whose income
      is includible in gross income for United States income tax purposes regardless
      of its source; (v) a trust, if a court within the United States is able to
      exercise primary supervision over the administration of the trust and one or
      more U.S. Persons have authority to control all substantial decisions of the

      in existence prior to August 20, 1996 that are treated as United States persons
      prior to such date and elect to continue to be treated as United States

    11. That
      the
      Purchaser agrees to such amendments of the Trust Agreement as may be required
      to
      further effectuate the restrictions on transfer of any Residual Certificate
      to

      person that does not satisfy the requirements of paragraph 7 and paragraph
      10
      hereof.

     

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

    In

              (1)

            	
              We
                understand that the Privately Offered Certificates have not been,

                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

                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

              (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 Certificate Registrar and the Depositor
                a
                certification from such transferee in the form hereof to confirm
                that the

                transaction not subject to, the registration requirements of the
                Securities Act. We further understand that the Privately Offered

                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.

    (2) To
      my
      knowledge, (a) the Reports, taken as a whole, do not contain any untrue
      statement of a material fact or omit to state a material fact necessary to

      report referred to below, taken as a whole, do not contain any untrue statement

      of
      compliance and attestation report;

      Agreement, and except as disclosed in the Reports, the Trustee has fulfilled
      its
      obligations under the Trust Agreement in all material respects; and

                    Class R Certificate will be issued in definitive, fully registered
                    form,

                  The
                    Class 1-A5 and Class 1-A6 Certificates will each be issued in
                    two
                    components: a Class I Component and a Class P Component, as described
                    herein. Each Class I Component will accrue interest at the rate
                    described
                    in the table above. Class P Components will not be issued with
                    an interest
                    rate or principal balance but will be entitled to amounts as
                    described
                    herein. The components are not
                    severable.
