    This
      TRUST AGREEMENT, dated as of February 1, 2007 (the “Agreement”), is by and
      among STRUCTURED ASSET SECURITIES CORPORATION, a Delaware corporation, as
      depositor (the “Depositor”), U.S. BANK NATIONAL ASSOCIATION, as trustee (the
“Trustee”), AURORA LOAN SERVICES LLC, as master servicer (the “Master
      Servicer”), WELLS FARGO BANK, N.A., as securities administrator (the “Securities
      Administrator”), and CLAYTON FIXED INCOME SERVICES INC., as credit risk manager
      (the “Credit Risk Manager”).

     

    PRELIMINARY
      STATEMENT

     

    The
      Depositor has acquired the Mortgage Loans from the Seller, and at the Closing
      Date is the owner of the Mortgage Loans and the other property being conveyed
      by
      it to the Trustee hereunder for inclusion in the Trust Fund. On the Closing
      Date, the Depositor will acquire the Certificates from the Trust Fund, as
      consideration for its transfer to the Trust Fund of the Mortgage Loans and
      the
      other property constituting the Trust Fund. The Depositor has duly authorized
      the execution and delivery of this Agreement to provide for the conveyance
      to
      the Trustee of the Mortgage Loans and the other property constituting the Trust
      Fund. All covenants and agreements made by the Seller in the Mortgage Loan
      Sale
      Agreement and by the Depositor, the Master Servicer, the Securities
      Administrator and the Trustee herein with respect to the Mortgage Loans and
      the
      other property constituting the Trust Fund are for the benefit of the Holders
      from time to time of the Certificates and, to the extent provided herein, any
      NIMS Insurer, the Swap Counterparty and the Cap Counterparty. The Depositor,
      the
      Trustee, the Master Servicer, the Securities Administrator and the Credit Risk
      Manager 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, an election shall be made that the Trust Fund (exclusive of
      (i)
      the Swap Agreement, (ii) the Swap Account, (iii) the right to receive and the
      obligation to pay Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls, (iv)
      the Basis Risk Reserve Fund, (v) the Supplemental Interest Trust, (vi) the
      Interest Rate Cap Agreement, (vii) the Interest Rate Cap Account, (viii) the
      Collateral Account, (ix) the right to receive FPD Premiums and (x) the
      obligation to pay Class I Shortfalls (collectively, the “Excluded Trust
      Assets”)) be treated for federal income tax purposes as comprising four real
      estate mortgage investment conduits under Section 860D of the Code (each a
      “REMIC” or, in the alternative “REMIC 1,” “REMIC 2,” “REMIC 3,” and “REMIC 4”
(REMIC 4 also being referred to as the “Upper Tier REMIC”)). Any inconsistencies
      or ambiguities in this Agreement or in the administration of this Agreement
      shall be resolved in a manner that preserves the validity of such REMIC
      elections.

     

    Each
      Certificate, other than the Class R and Class LT-R Certificates, represents
      ownership of a regular interest in the Upper Tier REMIC for purposes of the
      REMIC Provisions. In addition, each Certificate, other than the Class R, Class
      LT-R, Class X and Class P Certificates, represents (i) the right to receive
      payments with respect to any Basis Risk Shortfalls and Unpaid Basis Risk
      Shortfalls and (ii) the obligation to pay Class I Shortfalls. The Class LT-R
      Certificate represents ownership of the sole Class of residual interest in
      REMIC
      1. The Class R Certificate represents ownership of the sole Class of residual
      interest in each of REMIC 2, REMIC 3, and the Upper Tier REMIC for purposes
      of
      the REMIC Provisions.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    The
      Upper
      Tier REMIC shall hold as its assets the uncertificated Lower Tier Interests
      in
      REMIC 3, other than the Class LT3-R interest, and each such Lower Tier Interest
      is hereby designated as a regular interest in REMIC 3 for purposes of the REMIC
      Provisions. REMIC 3 shall hold as its assets the uncertificated Lower Tier
      Interests in REMIC 2, other than the Class LT2-R interest, and each such Lower
      Tier Interest is hereby designated as a regular interest in REMIC 2. REMIC
      2
      shall hold as its assets the uncertificated Lower Tier Interests in REMIC 1,
      and
      each such Lower Tier Interest is hereby designated as a regular interest in
      REMIC 1. REMIC 1 shall hold as its assets the property of the Trust Fund other
      than the Lower Tier Interests in REMIC 1, REMIC 2 and REMIC 3 and the Excluded
      Trust Assets.

     

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

     

    REMIC
      1:  

     

    REMIC
      1
      shall issue one uncertificated interest in respect of each Mortgage Loan held
      by
      the Trust Fund on the Closing Date, each of which is hereby designated as a
      regular interest in REMIC 1 (the “REMIC 1 Regular Interests”). REMIC 1 shall
      also issue the Class LT-R Certificate, which shall represent the sole class
      of
      residual interest in REMIC 1. Each REMIC 1 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 Qualifying
      Substitute Mortgage Loan is substituted for such Mortgage Loan (the “Original
      Mortgage Loan”), no amount of interest payable on such Qualifying Substitute
      Mortgage Loan shall be distributed on such REMIC 1 Regular Interest at a rate
      in
      excess of the Net Mortgage Rate of the Original Mortgage Loan.

     

    On
      each
      Distribution Date, the Trustee shall first pay or charge as an expense of
      REMIC 1 all expenses of the Trust Fund for such Distribution Date, other
      than any expenses in respect of the Swap Agreement.

     

    On
      each
      Distribution Date the Trustee shall distribute the aggregate Interest Remittance
      Amount (net of expenses described in the preceding paragraph) with respect
      to
      each of the Lower Tier Interests in REMIC 1 based on the above-described
      interest rates.

     

    On
      each
      Distribution Date, the Trustee shall distribute the aggregate Principal
      Remittance Amount among the Lower Tier Interests in REMIC 1 in accordance with
      the amount of the Principal Remittance Amount attributable to the Mortgage
      Loan
      corresponding to each such Lower Tier Interest in REMIC 1. All losses on the
      Mortgage Loans shall be allocated among the Lower Tier Interests in REMIC 1
      in
      the same manner that principal distributions are allocated.

     

    On
      each
      Distribution Date, the Trustee shall distribute the Prepayment Premiums
      collected during the preceding Prepayment Period to the Lower Tier Interest
      in
      REMIC 1 corresponding to the Mortgage Loan with respect to which such amounts
      were received.

      above-described interest rates.

      each
      Distribution Date, the Trustee shall distribute the aggregate Principal
      Remittance Amount with respect to the two Mortgage Pools with respect to the
      Lower Tier Interests in REMIC 2, first to the Class LT2-A Interest until its
      principal balance is reduced to zero, and then sequentially, to the other Lower
      Tier Interests in REMIC 2 in ascending order of their numerical class
      designation, and, with respect to each pair of classes having the same numerical
      designation, in equal amounts to each such class, until the principal balance
      of
      each such class is reduced to zero. All losses on the Mortgage Loans shall
      be
      allocated among the Lower Tier Interests in REMIC 2 in the same manner that
      principal distributions are allocated.

     

    On
      each
      Distribution Date, the Trustee shall distribute the Prepayment Premiums
      collected during the preceding Prepayment Period to the Class LT2-F71 Lower
      Tier
      Interest.

              For
                any Distribution Date (and the related Accrual Period) the interest
                rate
                for each of these Lower Tier Interests in REMIC 3 is a per annum
                rate
                equal to the weighted average of the interest rates on the Lower
                Tier
                Interests in REMIC 2 for such Distribution Date, provided,
                however, that
                for any Distribution Date on which the Class LT3-IO Interest is entitled
                to a portion of the interest accruals on a Lower Tier Interest in
                REMIC 2
                having an “F” in its class designation, as described in footnote two
                below, such weighted average shall be computed by first subjecting
                the
                rate on such Lower Tier Interest in REMIC 2 to a cap equal to Swap
                LIBOR
                for such Distribution Date.

              The
                Class LT3-IO is an interest only class that does not have a principal
                balance. For only those Distribution Dates listed in the first column
                in
                the table below, the Class LT3-IO shall be entitled to interest accrued
                on
                the Lower Tier Interest in REMIC 2 listed in the second column in
                the
                table below at a per annum rate equal to the excess, if any, of (i)
                the
                interest rate for such Lower Tier Interest in REMIC 2 for such
                Distribution Date over (ii) Swap LIBOR for such Distribution
                Date.

              This
                interest shall have an initial class principal amount equal to one-half
                of
                the initial Class Principal Amount of its Corresponding Class of
                Certificates.

            

    

     

    
      	 	
              (4)

            	
              This
                interest shall have an initial class principal amount equal to the
                excess
                of (i) the Aggregate Pool Balance as of the Cut-off Date, over (ii)
                the
                aggregate initial class principal amount of each other regular interest
                in
                REMIC 3.

              The
                Class LT3-R interest is the sole class of residual interests in REMIC
                3.
                It does not have an interest rate or a principal
                balance.

            

    

     

    On
      each
      Distribution Date, interest shall be distributed on the Lower Tier Interests
      in
      REMIC 3 based on the above-described interest rates,
      provided,
      however,
      that
      interest that accrues on the Class LT3-Q Interest shall be deferred in an amount
      equal to one-half of the increase, if any, in the Overcollateralization Amount
      for such Distribution Date. Any interest so deferred shall itself bear interest
      at the interest rate for the Class LT3-Q Interest. An amount equal to the
      interest so deferred shall be distributed as additional principal on the other
      Lower Tier Interests in REMIC 3 having a principal balance in the manner
      described under priority (a) below.

     

    On
      each
      Distribution Date principal shall be distributed, and Realized Losses shall
      be
      allocated, among the Lower Tier Interests in REMIC 3 in the following order
      of
      priority:

     

    (a)
      First, to the Class LT3-A1, Class LT3-A2, Class LT3-A3, Class LT3-A4, Class
      LT3-A5, Class LT3-M1, Class LT3-M2, Class LT3-M3, Class LT3-M4, Class
      LT3-M5, Class LT3-M6, Class LT3-M7, Class LT3-M8, Class LT3-M9, Class LT3-B1
      and
      Class LT3-B2 Interests until the principal balance of each such Lower Tier
      Interest equals one-half of the Class Principal Amount of the Corresponding
      Class of Certificates immediately after such Distribution Date; and

     

    (b)
      Second, to the Class LT3-Q Interest, any remaining amounts.

     

    On
      each
      Distribution Date, the Trustee shall be deemed to have distributed the
      Prepayment Premiums passed through with respect to the Class LT2-F71 Lower
      Tier
      Interest in REMIC 2 on such Distribution Date to the Class LT3-Q
      Interest.

                applicable; on any Distribution Date on which the Certificate Interest

                Class B2 Certificateholders to the Supplemental Interest Trust, all

              For
                purposes of the REMIC Provisions, Class X Certificates shall have
                an
                initial principal balance of $14,656,830.84, and the right to receive
                distributions of such amount represents a regular interest in the
                Upper
                Tier REMIC. The Class X Certificate shall also comprise two notional
                components, each of which represents a regular interest in the Upper
                Tier
                REMIC. The first such component has a notional balance that will
                at all
                times equal the aggregate of the Class Principal Amounts of the Lower
                Tier
                Interests in REMIC 3, and, for each Distribution Date (and the related
                Accrual Period) this notional component shall bear interest at a
                per annum
                rate equal to the excess, if any, of (i) (a) the weighted average
                of the
                interest rates on the Lower Tier Interests in REMIC 3 (other than
                any
                interest-only regular interest) minus (b) the Credit Risk Manager’s Fee
                Rate, over (ii) the Adjusted Lower Tier WAC. The second notional
                component
                represents the right to receive all distributions in respect of the
                Class
                LT3-IO Interest in REMIC 3 (the “Class LT4-I” interest). In addition, for
                purposes of the REMIC Provisions, the Class X Certificate shall represent
                beneficial ownership of (i) the Basis Risk Reserve Fund; (ii) the
                Supplemental Interest Trust, including the Swap Agreement, the Swap
                Account, the Interest Rate Cap Agreement and the Interest Rate Cap
                Account, (iii) any FPD Premiums and (iv) an interest in the notional
                principal contracts described in Section 10.01(n)
                hereof.

                and
                will not bear interest at a stated rate. The Class R Certificate
                represents ownership of the residual interest in the Upper Tier REMIC,
                as
                well as ownership of the Class LT2-R Interest and Class LT3-R Interest.
                The Class R Certificate will be issued as a single Certificate evidencing
                the entire Percentage Interest in such
                Class.

                the
                Holders of the Class P Certificates as provided in Section 5.02(i).
                For
                purposes of the REMIC Provisions, Class P shall represent a regular
                interest in the Upper Tier REMIC.

                and
                will not bear interest at a stated rate. The Class LT-R Certificate
                represents ownership of the residual interest in REMIC 1. The Class
                LT-R
                Certificate will be issued as a single Certificate evidencing the
                entire
                Percentage Interest in such Class.

        $200,000 during any Anniversary Year. In the event that the Trustee incurs
        reimbursable amounts in excess of $200,000, it may seek reimbursement for
        such
        amounts in subsequent Anniversary Years, but in no event shall more than
        $200,000 be reimbursed to the Trustee per Anniversary Year. Notwithstanding
        the
        foregoing, costs and expenses incurred by the Trustee pursuant to Section
        6.14(a) in connection with any transfer of servicing shall be excluded from
        the
        $200,000 per Anniversary Year limit on reimbursable amounts. For the avoidance
        of doubt, (i) the Interest Remittance Amount available on each Swap Payment
        Date
        for distributions to the Swap Account shall be equal to the Interest Remittance
        Amount on the related Distribution Date and (ii) the Interest Remittance
        Amount
        for each Distribution Date shall be calculated without regard to any
        distributions to the Swap Account on the related Swap Payment Date.

      LIBOR:
        (a)
        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 Securities Administrator
        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.

      (b) If
        on
        such a LIBOR Determination Date, the BBA’s Interest Settlement Rate does not
        appear on the Telerate Page 3750 as of 11:00 a.m. (London time), or if the
        Telerate Page 3750 is not available on such date, the Securities Administrator
        will obtain such rate first
        from
        Reuters’ “page LIBOR 01,” or if such page is not available, then from
        Bloomberg’s page “BBAM.” If any 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 Securities Administrator will designate an alternative
        index that has performed, or that the Securities Administrator expects to
        perform, in a manner substantially similar to the BBA’s Interest Settlement
        Rate. The Securities Administrator will select a particular index as the
        alternative index only if it receives an Opinion of Counsel (a copy of which
        shall be furnished to the Trustee and any NIMS Insurer), which opinion shall
        be
        an expense reimbursed from the Securities Administration Account pursuant
        to
        Section 4.05, that the selection of such index will not cause any of the
        REMICs
        to lose their classification as REMICs for federal income tax
        purposes.

       

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

      Concurrently
        with the execution of this Agreement, the MGIC Letter Agreement and the PMI
        Letter Agreement shall be delivered to the Trustee on behalf of the Trust
        Fund.
        In connection therewith, the Depositor hereby directs the Trustee (solely
        in its
        capacity as such) and the Trustee is hereby authorized to execute and deliver
        the MGIC Letter Agreement and the PMI Letter Agreement for the benefit of
        the
        Certificateholders. The Seller, the Master Servicer, the Securities
        Administrator, the Depositor, the Servicers and the Certificateholders (by
        their
        acceptance of such Certificates) acknowledge and agree that the Trustee is
        executing and delivering the MGIC Letter Agreement and the PMI Letter Agreement
        solely in its capacity as Trustee of the Trust Fund, and not in its individual
        capacity.

      Concurrently
        with the execution of this Agreement, the Swap Agreement and the Interest
        Rate
        Cap Agreement shall be delivered to the Trustee. In connection therewith,
        the
        Depositor hereby directs the Trustee (solely in its capacity as such) and
        the
        Trustee is hereby authorized to execute and deliver the Swap Agreement and
        the
        Interest Rate Cap Agreement (each on behalf of the Supplemental Interest
        Trust)
        for the benefit of, the Certificateholders. The Seller, the Master Servicer,
        the

        and
        agree that the Trustee is executing and delivering the Swap Agreement and
        the
        Interest Rate Cap Agreement solely in its capacity as Trustee of the
        Supplemental Interest Trust and not in its individual capacity. The Trustee
        shall have no duty or responsibility to enter into any other swap agreement
        or
        interest rate cap agreement upon the expiration or termination of the Swap
        Agreement or the Interest Rate Cap Agreement other than as provided in Section
        5.09(a) and (b), respectively.

       

      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
        Agreement, but only to the extent assigned under the Mortgage Loan Sale
        Agreement. The Trustee hereby accepts such assignment, and shall be entitled
        to
        exercise all the rights of the Depositor under the Mortgage Loan Sale Agreement
        as if, for such purpose, it were the Depositor. 

       

      It
        is
        agreed and understood by the Depositor and the Trustee (and the Seller has
        so
        represented and recognized in the Mortgage Loan Sale Agreement) that it is
        not
        intended that any Mortgage Loan to be included in the Trust Fund be (i) a
        “High-Cost Home Loan” as defined in the New Jersey Home Ownership Act effective

        Indiana Home Loan Practices Act effective January 1, 2005.

       

      The
        foregoing sale, transfer, assignment, set-over, deposit and conveyance does
        not
        and is not intended to result in the creation or assumption by the Trustee
        of
        any obligation of the Depositor, the Seller or any other Person in connection
        with the Mortgage Loans. 

       

      The
        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.

       

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

        to
        any lost Mortgage Note, a lost note affidavit stating that the original Mortgage
        Note was lost, misplaced or destroyed, together with a copy of the related
        Mortgage Note;

        respect to any Mortgage Loan other than a Cooperative Loan, the original

        connection with any Mortgage Loan, the Depositor cannot deliver the Mortgage
        or
        power of attorney with evidence of recording thereon on or prior to the Closing
        Date because of a delay caused by the public recording office where such
        Mortgage has been delivered for recordation or because such Mortgage or power
        of
        attorney has been lost, the Depositor shall deliver or cause to be delivered
        to
        the Trustee (or the Custodian), in the case of a delay due to recording,
        a true
        copy of such Mortgage or power of attorney, pending delivery of the original

        the
        Custodian) is a true copy and that the original of such Mortgage or power
        of
        attorney has been forwarded to the public recording office, or, in the case
        of a
        Mortgage or power of attorney that has been lost, a copy thereof (certified
        as
        provided for under the laws of the appropriate jurisdiction) and a written
        Opinion of Counsel acceptable to the Trustee and the Depositor that an original

        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 Custodian) is a true

        applicable, such original intervening assignments of the Mortgage, notice

        necessary to show a complete chain of assignment from the originator, or,
        in the
        case of an Intervening Assignment that has been lost, a written Opinion of
        Counsel acceptable to the Trustee and any NIMS Insurer that such original
        Intervening Assignment is not required to enforce the Trustee’s interest in the
        Mortgage Loan;

      (viii)
         if
        applicable, the original Primary Mortgage Insurance Policy or certificate
        or, an
        electronic certification evidencing the existence of the Primary Mortgage
        Insurance Policy or certificate, if private mortgage guaranty insurance is
        required;

       

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

        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 need not be recorded if, on or prior to the Closing Date,
        the
        Depositor delivers, at its own expense, an Opinion of Counsel addressed to
        the
        Trustee (which must be Independent counsel) acceptable to the Trustee and
        the
        Rating Agencies, to the effect that recording in such states is not required
        to
        protect the Trustee’s interest in the related Non-MERS Mortgage Loans;
provided,
        further,
        that
        notwithstanding the delivery of any Opinion of Counsel, the Master Servicer
        shall direct the applicable Servicer to submit each Assignment of Mortgage
        for
        recording upon the occurrence of a bankruptcy, insolvency or foreclosure
        relating to the Mortgagor under the related Mortgage. Subject to the preceding
        sentence, as soon as practicable after the Closing Date (but in no event
        more
        than three months thereafter except to the extent delays are caused by the
        applicable recording office), the Master Servicer, at the expense of the
        Depositor and with the cooperation of the applicable Servicer, shall direct
        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.

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

       

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

       

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

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

              

      

       

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

       

      (b) Within
        45
        days after the Closing Date, the Trustee or the Custodian on behalf of the
        Trustee, will, for the benefit of Holders of the Certificates, review each
        Mortgage File to ascertain that all required documents set forth in Section
        2.01
        have been received and appear on their face to contain the requisite signatures
        by or on behalf of the respective parties thereto, and shall deliver to the
        Trustee, the Depositor, the Master Servicer and any NIMS Insurer an Interim
        Certification in the form annexed hereto as Exhibit B-2 (or in the form annexed
        to the 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 Custodian on behalf of the Trustee, shall determine
        whether such documents are executed and endorsed, but shall be under no duty
        or
        obligation to inspect, review or examine any such documents, instruments,
        certificates or other papers to determine that the same are valid, binding,
        legally effective, properly endorsed, genuine, enforceable or appropriate
        for
        the represented purpose or that they have actually been recorded or are in
        recordable form or that they are other than what they purport to be on their
        face. Neither the Trustee nor the Custodian shall have any responsibility
        for
        verifying the genuineness or the legal effectiveness of or authority for
        any
        signatures of or on behalf of any party or endorser.

       

      
        
          
          

        

        
          66

          
            

          

        

        
          
          

        

      

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

       

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

       

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

      (f) Each
        of
        the parties hereto acknowledges that the Custodian shall perform the applicable
        review of the Mortgage Loans and respective certifications thereof as provided
        in this Section 2.02 and the Custodial Agreement. The Trustee, solely in
        its
        capacity as Trustee hereunder, is hereby authorized and directed by the
        Depositor to appoint the Custodian and to execute and deliver the Custodial
        Agreement.

       

      (g) Upon
        execution of this Agreement, the Depositor hereby delivers to the Trustee
        and
        the Trustee acknowledges a receipt of the Mortgage Loan Sale Agreement, each
        Servicing Agreement and the Bulk PMI Policies. The Depositor hereby directs
        the
        Trustee, solely in its capacity as Trustee hereunder, to execute and deliver,
        concurrently with the execution and delivery of this Agreement, the Bulk
        PMI
        Policies and each Servicing Agreement to which the Trustee is a
        party.

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

       

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

       

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

       

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

       

      (iv)
         this
        Agreement has been duly executed and delivered by the Depositor and, assuming
        due authorization, execution and delivery by the Trustee, the Securities
        Administrator, the Master Servicer and the Credit Risk Manager, constitutes
        a
        valid and binding obligation of the Depositor enforceable against it in
        accordance with its terms except as such enforceability may be subject to
        (A)
        applicable bankruptcy and insolvency laws and other similar laws affecting
        the
        enforcement of the rights of creditors generally and (B) general principles

        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.

                Discovery
                  of Breach. 

              

      

       

      It
        is
        understood and agreed that the representations and warranties (i) of the
        Depositor set forth in Section 2.03, (ii) of the Seller set forth in the
        Mortgage Loan Sale Agreement and assigned to the Depositor by the Seller
        under
        the Mortgage Loan Sale Agreement and to the Trustee by the Depositor hereunder
        and (iii) of the Servicers assigned by the Seller to the Depositor pursuant
        to
        the Mortgage Loan Sale Agreement and assigned to the Trustee by the Depositor
        hereunder, shall each survive delivery of the Mortgage Files and the Assignment
        of Mortgage of each Mortgage Loan to the Trustee and shall continue throughout
        the term of this Agreement. Upon discovery by any of the Depositor, the Master
        Servicer, the Securities Administrator or the Trustee of a breach of any
        of such
        representations and warranties that adversely and materially affects the
        value
        of the related Mortgage Loan, the party discovering such breach shall give
        prompt written notice to the other parties. Within 90 days of the discovery
        of a
        breach of any representation or warranty given to the Trustee by the Depositor
        or the Seller, the Depositor or the Seller, as applicable, shall either (a)
        cure
        such breach in all material respects, (b) repurchase such Mortgage Loan or
        any
        property acquired in respect thereof from the Trustee at the Purchase Price
        (or
        in the case of a First Payment Default Mortgage Loan, the FPD Purchase Price
        (excluding any FPD Premium)) or (c) within the two-year period following
        the
        Closing Date, substitute a Qualifying Substitute Mortgage Loan for the affected
        Mortgage Loan.

                Repurchase,
                  Purchase or Substitution of Mortgage Loans.

              

      

       

      (a) With
        respect to any Mortgage Loan repurchased by the Depositor pursuant to this
        Agreement or by the Seller pursuant to the Mortgage Loan Sale Agreement,
        the
        principal portion of the funds (including the FPD Purchase Price (excluding
        any
        FPD Premium) 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 (excluding
        any FPD Premium), as applicable, shall be deposited in the Certificate Account.
        The Trustee (i) upon receipt of the full amount of the Purchase Price for
        a
        Deleted Mortgage Loan, (ii) upon receipt of a written certification from
        the
        Master Servicer that it has received the full amount of the Purchase Price
        for a
        Deleted Mortgage Loan and has deposited such amount in the Collection Account
        or
        (iii) upon receipt of notification from the Custodian that it had received
        the
        Mortgage File for a Qualifying Substitute Mortgage Loan substituted for a
        Deleted Mortgage Loan (and any applicable Substitution Amount), shall release
        or
        cause to be released and reassign to the Depositor or the Seller, 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 related Servicer and the Trustee shall have no further responsibility
        with
        respect to the Mortgage File relating to such Deleted Mortgage Loan. The
        Seller
        indemnifies and holds the Trust Fund, the Master Servicer, the Securities
        Administrator, the Trustee, the Depositor, and NIMS Insurer 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 Securities
        Administrator, the Trustee, the Master Servicer, the Depositor, any NIMS
        Insurer
        and any Certificateholder may sustain in connection with any actions of such
        Seller relating to a repurchase of a Mortgage Loan other than in compliance
        with
        the terms of this Section 2.05 and the Mortgage Loan Sale Agreement, to the
        extent that any such action causes an Adverse REMIC Event.

       

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

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

                Grant
                  Clause. 

              

      

       

      (a) It
        is
        intended that the conveyance of the Depositor’s right, title and interest in and
        to property constituting the Trust Fund pursuant to this Agreement shall
        constitute, and shall be construed as, a sale of such property and not a
        grant
        of a security interest to secure a loan. However, if such conveyance is deemed
        to be in respect of a loan, it is intended that: (1) the rights and obligations
        of the parties shall be established pursuant to the terms of this Agreement;
        (2)
        the Depositor hereby grants to the Trustee for the benefit of the Holders
        of the
        Certificates a first priority security interest to secure repayment of an
        obligation in an amount equal to the aggregate Class Principal Amount of
        the
        Certificates (or the aggregate principal balance of the Lower Tier REMIC
        1
        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, the Supplemental Interest Trust and all proceeds
        of
        any and all property constituting the Trust Fund and the Supplemental Interest
        Trust to secure payment of the Certificates or Lower Tier REMIC 1 Uncertificated
        Regular Interests, as applicable (such security interest being, to the extent
        of
        the assets that constitute the Supplemental Interest Trust, pari
        passu
        with the
        security interest as provided in clause (4) below); (3) this Agreement shall
        constitute a security agreement under applicable law; and (4) the Swap
        Counterparty shall be deemed, during the term of such agreement and while
        such
        agreement is the property of the Trustee, to have a security interest in
        all of
        the assets that constitute the Supplemental Interest Trust, but only to the
        extent of such Swap Counterparty’s right to payment under the Swap Agreement
        (such security interest being pari
        passu
        with the
        security interest as provided in clause (2) above). If such conveyance is
        deemed
        to be in respect of a loan and the trust created by this Agreement terminates
        prior to the satisfaction of the claims of any Person holding any Certificate
        or
        Lower Tier REMIC 1 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 shall
        be
        maintained as such throughout the term of this Agreement. The Depositor shall,
        at its own expense, make all initial filings on or about the Closing Date
        and
        shall forward a copy of such filing or filings to the Trustee. Without limiting
        the generality of the foregoing, the Depositor shall prepare and forward
        for
        filing, or shall cause to be forwarded for filing, at the expense of the
        Depositor, all filings necessary to maintain the effectiveness of any original
        filings necessary under the relevant UCC to perfect the Trustee’s security
        interest in or lien on the Mortgage Loans, including without limitation (x)
        continuation statements, and (y) such other statements as may be occasioned
        by
        (1) any change of name of the Seller, the Depositor or the Trustee, (2) any
        change of location of the jurisdiction of organization of the Seller or the
        Depositor, (3) any transfer of any interest of the Seller or the Depositor
        in
        any Mortgage Loan or (4) any change under the relevant UCC or other applicable
        laws. Neither the Seller nor the Depositor shall organize under the law of
        any
        jurisdiction other than the State under which each is organized as of the
        Closing Date (whether changing its jurisdiction of organization or organizing
        under an additional jurisdiction) without giving 30 days prior written notice
        of
        such action to its immediate and intermediate transferee, including the Trustee.
        Before effecting such change, the Seller or the Depositor proposing to change
        its jurisdiction of organization shall prepare and file in the appropriate
        filing office any financing statements or other statements necessary to continue
        the perfection of the interests of its immediate and intermediate 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 immediate or intermediate 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).

                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 in the Percentage Interests, specified herein. Each Class of
        Book-Entry Certificates will be issued in the minimum denominations in
        Certificate Principal Amount specified in the Preliminary Statement hereto
        and
        in integral multiples of $1 in excess thereof. The Class P and Class X
        Certificates shall each be maintained in definitive, fully registered form
        in
        the minimum denomination specified in the Preliminary Statement hereto and
        in
        integral multiples of 1% in excess thereof. Each of the Class R and Class
        LT-R
        Certificate shall be issued as a single Certificate and maintained in
        definitive, fully registered form in a minimum denomination equal to 100%
        of the
        Percentage Interest of such Class. The Certificates may be issued in the
        form of
        typewritten certificates. 

       

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

      (c) The
        Class
        B1 and Class B2 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 shall be deposited on behalf of the subscribers for such
        Certificates represented thereby with the Trustee, as custodian for The
        Depository Trust Company (“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.

       

      (d) The
        Class
        B1 and Class B2 Certificates sold in offshore transactions in reliance on
        Regulation S shall be issued initially in the form of one or more permanent
        global Certificates in definitive, fully registered form without interest
        coupons with the applicable legends set forth in Exhibit A hereto added to
        the
        forms of such Certificates (each, a “Regulation S Global Security”), which shall
        be deposited on behalf of the subscribers for such Certificates represented
        thereby with the Trustee, as custodian for DTC and registered in the name
        of a
        nominee of DTC, duly executed and authenticated by the Trustee 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.

       

      (e) The
        Class
        B1 and Class B2 Certificates sold to an “accredited investor” under Rule
        501(a)(1), (2), (3) or (7) under the Securities Act shall be issued initially
        in
        the form of one or more Definitive Certificates.

      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 1 Uncertificated Regular Interests) 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 1 Uncertificated
        Regular Interests) (the “Certificate Register”). The Trustee may appoint a bank
        or trust company to act as Certificate Registrar. A registration book shall
        be
        maintained for the Certificates (and Lower Tier REMIC 1 Uncertificated Regular
        Interests, as the case may be) collectively. The Certificate Registrar may
        resign or be discharged or removed and a new successor may be appointed in
        accordance with the procedures and requirements set forth in Sections 6.06
        and
        6.07 hereof with respect to the resignation, discharge or removal of the
        Trustee
        and the appointment of a successor Trustee. The Certificate Registrar may
        appoint, by a written instrument delivered to the Holders, any NIMS Insurer
        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 1 Uncertificated Regular
        Interests, which notice shall contain a certification that such transferee
        is a
        permitted LTURI-holder hereunder. The Lower Tier REMIC 1 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 1
        Uncertificated Regular Interests are registered on the books of the Certificate
        Registrar as the LTURI-holder for all purposes hereunder.

                Transfer
                  and Exchange of Certificates. 

              

      

       

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

       

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

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

       

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

       

      (i)
         The
        Certificate Registrar shall register the transfer of a Restricted Certificate
        if
        the requested transfer is (x) to the Depositor or an affiliate (as defined
        in
        Rule 405 under the Securities Act) of the Depositor or (y) being made to
        a
“qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the
        Securities Act 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, or to any Person all
        of the
        equity owners in which are such accredited investors, by a transferor who
        furnishes to the Trustee a letter of the transferee substantially in the
        form of
        Exhibit G hereto.

       

      (d) (i)
        No
        transfer of an ERISA-Restricted Certificate in the form of a Definitive
        Certificate shall be made to any Person 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) an Opinion
        of
        Counsel 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 Securities Administrator, the Master Servicer, any Servicer,
        any
        NIMS Insurer 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, counsel satisfactory to the Trustee,
        has
        rendered an opinion 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 Securities Administrator,
        the Master Servicer, any NIMS Insurer or the Depositor.

       

      
        
          
          

        

        
          75

          
            

          

        

        
          
          

        

      

      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 any such 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.

       

      (ii)
        No
        transfer of an ERISA-Restricted Trust Certificate shall be made prior to
        the
        termination of the Swap Agreement and the Interest Rate Cap Agreement, unless
        the Trustee shall have received a representation letter from the transferee
        of
        such Certificate, substantially in the form set forth in Exhibit H, to the
        effect that either (i) such transferee is neither a Plan nor a Person acting
        on
        behalf of any such Plan or using the assets of any such Plan to effect such
        transfer or (ii) the acquisition and holding of the ERISA-Restricted Trust
        Certificate are eligible for exemptive relief under Prohibited Transaction
        Class
        Exemption (“PTCE”) 84-14, PTCE 90-1, PTCE 91-38, PTCE 95-60 or PTCE 96-23.
        Notwithstanding anything else to the contrary herein, prior to the termination
        of the Swap Agreement and the Interest Rate Cap Agreement, any purported
        transfer of an ERISA-Restricted Trust Certificate on behalf of a Plan without
        the delivery to the Trustee of a representation letter as described above
        shall
        be void and of no effect. If the ERISA-Restricted Trust Certificate is a
        Book-Entry Certificate, prior to the termination of the Swap Agreement and
        the
        Interest Rate Cap Agreement, the transferee will be deemed to have made a
        representation as provided in clause (i) or (ii) of this paragraph, as
        applicable.

       

      If
        any
        ERISA-Restricted Trust Certificate, or any interest therein, is acquired
        or held
        in violation of the provisions of the preceding paragraph, the next preceding
        permitted beneficial owner will be treated as the beneficial owner of that
        Certificate, retroactive to the date of transfer to the purported beneficial
        owner. Any purported beneficial owner whose acquisition or holding of an
        ERISA-Restricted Trust Certificate, or interest therein, was effected in
        violation of the provisions of the preceding paragraph shall indemnify to
        the
        extent permitted by law and hold harmless the Depositor, the Trustee, the
        Securities Administrator, any NIMS Insurer and the Master Servicer from and
        against any and all liabilities, claims, costs or expenses incurred by such
        parties as a result of such acquisition or holding.

       

      
        
          
          

        

        
          76

          
            

          

        

        
          
          

        

      

      To
        the
        extent permitted under applicable law (including, but not limited to, ERISA),
        the Trustee shall be under no liability to any Person for any registration
        of
        transfer of any ERISA-Restricted Trust Certificate that is in fact not permitted
        by this Section 3.03(d)(ii) 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.

       

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

       

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

       

      
        
          
          

        

        
          77

          
            

          

        

        
          
          

        

      

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

       

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

       

      (h) Notwithstanding
        any provision to the contrary herein, so long as a Global Security representing
        any Class B1 or Class B2 Certificate remains outstanding and is held by or
        on
        behalf of DTC, transfers of a Global Security representing any such
        Certificates, in whole or in part, shall only be made in accordance with
        Section
        3.01 and this Section 3.03(h).

       

      (A) Subject
        to clauses (B) and (C) of this Section 3.03(h), transfers of a Global Security
        representing any Class B1 or Class B2 Certificate 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
        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
        M-1
        hereto given by the holder of such beneficial interest stating that the exchange
        or transfer of such interest has been made in compliance with the transfer
        restrictions applicable to the Global Securities, including that the holder
        is
        not a U.S. person, and pursuant to and in accordance with Regulation S, the
        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 of 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 M-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.

      (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 the Regulation S Global Security to U.S. persons
        (as
        defined in Regulation S) shall be limited to transfers made pursuant to the
        provisions of Section 3.03(h)(C).

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

                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 and the Authenticating
        Agent
        and any NIMS Insurer 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. 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.

      Subject
        to the provisions of Section 3.09 with respect to Book-Entry Certificates,
        the
        Depositor, the Master Servicer, the Trustee, the Securities Administrator,
        the
        Certificate Registrar, any NIMS Insurer 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 none of the Depositor, the Master Servicer, the
        Trustee, the Securities Administrator, the Certificate Registrar, any NIMS
        Insurer or any agent of any of them shall be affected by notice to the
        contrary.

                  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.

                Appointment
                  of Paying Agent. 

              

      

       

      (a) The
        Trustee, subject to the consent of the NIMS Insurer, 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 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 shall be the Paying Agent.

      (b) Any
        Paying Agent shall comply with its reporting obligations under Regulation
        AB
        with respect to the Trust Fund in form and substance similar to those of
        the
        Trustee pursuant to Section 6.20, and the related assessment of compliance
        and
        attestation shall cover, at a minimum, the elements of the servicing criteria
        applicable to the Paying Agent indicated in Exhibit S attached hereto; provided
        that if the Trustee is the Paying Agent, any reporting obligations under
        Regulation AB specific to the Paying Agent shall be undertaken by the
        Trustee in the course of its own reporting and not separately. For so long
        as
        the Depositor is subject to Exchange Act reporting requirements with respect
        to
        the Trust, the Paying Agent shall give prior written notice to the Sponsor,
        the
        Master Servicer, the Securities Administrator 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 such Subcontractor.
        In
        addition, for so long as the Depositor is subject to Exchange Act reporting
        requirements with respect to the Trust, the Paying Agent shall notify the
        Sponsor, the Master Servicer, the Securities Administrator and the Depositor
        within five (5) calendar days of knowledge thereof (i) of any legal proceedings
        pending against the Paying Agent of the type described in Item 1117 (§ 229.1117)
        of Regulation AB, (ii) any merger, consolidation or sale of substantially
        all of
        the assets of the Paying Agent and (iii) if the Paying Agent shall become
        (but
        only to the extent not previously disclosed) at any time an affiliate of
        any of
        the parties listed on Exhibit V hereto or any of their affiliates. On or
        before
        March 1st
        of each
        year, the Depositor shall furnish any change in the information in Exhibit
        V to
        the Paying Agent and the Securities Administrator.

       

      (c) Any
        Paying Agent agrees to indemnify the Depositor, the Securities Administrator
        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(e)(iv) and Section 9.25(a). This indemnification shall survive
        the
        termination of this Agreement or the termination of such Paying Agent
        hereunder.

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

       

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

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

       

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

       

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

       

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

       

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

      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 BNC Mortgage Loan Trust 2007-1 Mortgage Pass-Through Certificates, Series
        2007-1.” The Collection Account shall relate solely to the Certificates and to
        the Lower Tier REMIC 1 Uncertificated Regular Interests 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 10 days and transfer
        all funds and investment property on deposit in such existing Collection
        Account
        into such new Collection Account.

       

      (c) The
        Master Servicer shall give to the Trustee and the Securities Administrator
        prior
        written notice of the name and address of the depository institution at which
        the Collection Account is maintained and the account number of such Collection
        Account. The Master Servicer shall take such actions as are necessary to
        cause
        the depository institution holding the Collection Account to hold such account
        in the name of the Master Servicer under this Agreement. 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), other than amounts not
        included in the Total Distribution Amount for such Distribution Date shall
        be
        remitted to the Securities Administrator for deposit into the Securities
        Administration Account by wire transfer in immediately available funds. The
        Master Servicer, at its option, may choose to make daily remittances from
        the
        Collection Account to the Securities Administrator for deposit into the
        Securities Administration Account.

       

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

       

      
        
          
          

        

        
          84

          
            

          

        

        
          
          

        

      

      (i)
         all
        payments on account of principal, including Principal Prepayments, any
        Subsequent Recovery and any Scheduled Payment attributable to principal received
        after its related Due Date, on the Mortgage Loans;

       

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

       

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

       

      (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)
         any
        Seller Remittance Amounts remitted by a Servicer;

       

      (vii)
         all
        amounts paid by any Servicer with respect to Net Simple Interest Shortfalls
        and
        Prepayment Interest Shortfalls; and 

       

      (viii)
         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
        any
        purchase price paid by any NIMS Insurer for the purchase of any Distressed
        Mortgage Loan under Section 7.04.

       

      The
        Master Servicer shall also deposit from its own funds into the Collection
        Account (to the extent not already received from the related Servicer), without
        right of reimbursement, except from Net Simple Interest Excess, an amount
        equal
        to any Net Simple Interest Shortfall (to the extent not offset by Net Simple
        Interest Excess) for the related Collection Period.

       

      (e) Funds
        in
        the Collection Account may be invested in Eligible Investments selected by
        and
        at the written direction of the Master Servicer, which shall mature not later
        than one Business Day prior to the Master Servicer Remittance Date (except
        that
        if such Eligible Investment is an obligation of the Securities Administrator,
        then such Eligible Investment shall mature not later than such applicable
        Master
        Servicer Remittance Date) and any such Eligible Investment shall not be sold
        or
        disposed of prior to its maturity. All such Eligible Investments shall be
        made
        in the name of the Master Servicer in trust for the benefit of the Trustee
        and
        Holders of the BNC Mortgage Loan Trust 2007-1 Mortgage Pass-Through
        Certificates, Series 2007-1. All income and gain realized from any Eligible
        Investment shall be for the benefit of the Master Servicer and shall be subject
        to its withdrawal or order from time to time, subject to Section 5.05 hereof,
        and shall not be part of the Trust Fund. The amount of any losses incurred
        in
        respect of any such investments shall be deposited in such Collection Account
        by
        the Master Servicer out of its own funds, without any right of reimbursement
        therefor, immediately as realized. The foregoing requirements for deposit
        in the
        Collection Account are exclusive, it being understood and agreed that, without
        limiting the generality of the foregoing, payments of interest on funds in
        the
        Collection Account and payments in the nature of late payment charges,
        assumption fees and other incidental fees and charges relating to the Mortgage
        Loans (other than Prepayment Premiums) need not be deposited by the Master
        Servicer in the Collection Account and may be retained by the Master Servicer
        or
        the applicable Servicer as additional servicing compensation. If the Master
        Servicer deposits in the Collection Account any amount not required to be
        deposited therein, it may at any time withdraw such amount from such Collection
        Account.

                Section
                  4.02

              	
                Application
                  of Funds in the Collection Account.

              

      

       

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

       

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

       

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

       

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

       

      
        
          
          

        

        
          86

          
            

          

        

        
          
          

        

      

      (iv)
         to
        the
        extent of any previous Advances made by the Master Servicer with respect
        to
        Simple Interest Mortgage Loans, to pay itself an amount equal to Net Simple
        Interest Excess for the related Collection Period to the extent not offset
        by
        Net Simple Interest Shortfalls;

       

      (v)
         to
        reimburse itself or any Servicer for expenses incurred by and recoverable
        by or
        reimbursable to it or any Servicer pursuant to this Agreement, including,
        without limitation, Sections 9.04, 9.05(b), 9.07(a), 9.30 or 11.15;

       

      (vi)
         to
        pay to
        the Seller any Seller Remittance Amount;

       

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

       

      (viii)
         if
        applicable, to pay the PMI Insurance Premium with respect to each Bulk PMI
        Policy;

       

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

       

      (x)
         to
        make
        payments to the Securities Administrator for deposit into the Securities
        Administration Account in the amounts and in the manner provided
        herein;

       

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

       

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

       

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

       

      (xiv)
         to
        reimburse the Trustee, the Securities Administrator, 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 Securities Administrator or a successor master servicer
        appointed by the Trustee pursuant to Section 6.14, in each case to the extent
        not reimbursed by the terminated Master Servicer, it being understood, in
        the
        case of any such reimbursement or payment, that the right of the Master
        Servicer, the Trustee or the Securities Administrator or other successor
        master
        servicer thereto shall be prior to the rights of the Certificateholders;
        and

       

      
        
          
          

        

        
          87

          
            

          

        

        
          
          

        

      

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

       

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

      (a) On
        each
        Distribution Date, the Securities Administrator shall have prepared (based
        solely on information provided by the Master Servicer, the Cap Counterparty
        and
        the Swap Counterparty) and shall make available to the Trustee, the Paying
        Agent, any NIMS Insurer, the Swap Counterparty, the Credit Risk Manager,
        the
        Seller and each Certificateholder a report (the “Distribution Date Statement”)
        setting forth the following information (on the basis of Mortgage Loan level
        information obtained from the Master Servicer):

        aggregate amount of the distribution to be made on such Distribution Date
        to the
        Holders of each Class of Certificates, to the extent applicable, allocable
        to
        principal on the Mortgage Loans, including Liquidation Proceeds and Insurance
        Proceeds, stating separately the amount attributable to scheduled principal
        payments and unscheduled payments in the nature of principal;

       

      (ii)
         the
        aggregate amount of the distribution to be made on such Distribution Date
        to the

      (b) Upon
        the
        reasonable advance written request of any NIMS Insurer or any Certificateholder
        that is a savings and loan, bank or insurance company, which request, if
        received by the Trustee, shall be promptly forwarded to the Securities
        Administrator, the Securities Administrator shall provide, or cause to be

        shall use reasonable efforts to obtain such information and documentation
        from

        Certificateholder or the NIMS Insurer for the actual expenses incurred in
        providing such reports and access.

        basis as may be required to enable any NIMS Insurer and such Holders to prepare

        however,

        in any
        other format permitted by the Code. The Securities Administrator shall 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).

        shall
        be an Eligible Account and shall be for the benefit of the Certificateholders,
        subject to the rights of the Trustee set forth herein. If the existing

      (b) The
        Trustee shall deposit or cause to be deposited into the Certificate Account,
        on

        immediately following the day on which, any monies are remitted by the
        Securities Administrator to the Trustee, all such amounts. The Trustee shall
        make withdrawals from the Certificate Account only for the following
        purposes:

       

      (i)
         to
        make
        payment to itself pursuant to any provision of this Agreement or to reimburse
        itself for any fees or expenses reimbursable to it pursuant to Section 6.12;
        provided,
        however,
        that
        any amounts in excess of the annual cap described in clause (b) of the
        definition of “Interest Remittance Amount” and clause (b) of the definition of
“Principal Remittance Amount” in any Anniversary Year, other than costs and

        and paid to the Trustee and the Trustee’s reimbursement for such excess amounts
        shall be made pursuant to Section 5.02(b)(v);

       

      (ii)

      (iii)

        payments to itself and others pursuant to any provision of this Agreement;
        

       

      (iv)
         to
        make
        distributions to Certificateholders pursuant to Article V; and

       

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

       

      (c) Funds
        in
        the Certificate Account may be invested by the Trustee at the direction of
        the
        Master Servicer in Eligible Investments (which may be obligations of the
        Trustee
        or its affiliates). If invested, all such investments must be payable on
        demand
        or mature no later than one Business Day prior to the next Distribution Date
        (unless such investments are obligations of the Trustee, in its individual
        capacity, in which case such investments may mature on the related Distribution
        Date), and shall not be sold or disposed of prior to their maturity. All
        such
        Eligible Investments will be made in the name of the Trustee (in its capacity
        as
        such) or its nominee. All income and gain realized from any such investment
        for
        each Distribution Date shall be compensation (1) to the Trustee, in payment
        of
        its Trustee Fee to the extent not paid by the Securities Administrator when
        due,
        (2) to the Custodian in payment of its Custodial Compensation to the extent
        not
        paid by the Securities Administrator when due and (3) to the Master Servicer,
        any income and gain remaining. Subject to the preceding sentence, all income
        and
        gain realized from any such investment for each Distribution Date shall be
        subject to withdrawal by the Master Servicer from time to time. The amount
        of
        any losses incurred in respect of any such investments shall be paid by the

                  Administration Account.

              

      

       

      (a) On
        the
        Closing Date, the Securities Administrator shall open and shall thereafter
        maintain an account to be held in trust (the “Securities Administration
        Account”), entitled “Wells Fargo Bank, N.A., as Securities Administrator, in
        trust for the benefit of the Holders of BNC Mortgage Loan Trust 2007-1 Mortgage
        Pass-Through Certificates, Series 2007-1.” The Securities Administration Account
        shall relate solely to the Certificates issued by the Trust Fund hereunder,
        and

        any
        other monies.

       

      (b) The
        Securities Administration Account shall be an Eligible Account. If an existing
        Securities Administration Account ceases to be an Eligible Account, the
        Securities Administrator shall establish a new Securities Administration
        Account
        that is an Eligible Account within 10 Business Days of notice thereof to
        the
        Securities Administrator, and shall transfer all funds on deposit in such
        existing Securities Administration Account into such new Securities
        Administration Account.

       

      (c) The
        Securities Administrator shall make withdrawals from the Securities
        Administration Account only for the following purposes:

         to
        make
        payments of any investment income or earnings on the Securities Administration
        Account to (A) the Trustee to pay the Trustee Fee, if due, (B) the Custodian
        to
        pay the Custodial Compensation, if due and (C) then any remaining amounts
        of
        investment income or earnings to itself;

       

      (iii)
         to
        reimburse itself for any amounts reimbursable under the terms of this
        Agreement;

       

      (iv)
         to
        make
        payments to the Trustee for deposit into the Certificate Account pursuant
        to
        Section 4.04; and

       

      
        
          
          

        

        
          94

          
            

          

        

        
          
          

        

      

      (v)

        clear
        and terminate the Securities Administration Account pursuant to Section
        7.02.

       

      (d) The
        Securities Administrator shall give to the Trustee prior written notice of
        the
        name and address of the depository institution at which the Securities
        Administration Account is maintained and the account number of such Securities
        Administration Account. On each Deposit Date, the entire amount on deposit
        in
        the Securities Administration Account (less any amounts withdrawn pursuant
        to
        Section 4.05(c)(i) and (ii)), shall be remitted to the Trustee for deposit
        into
        the Certificate Account by wire transfer in immediately available funds.
        The
        Securities Administrator, at its option, may choose to make daily remittances
        from the Securities Administration Account to the Trustee for deposit into
        the
        Certificate Account.

       

      (e) The
        Securities Administrator shall cause to be deposited into the Securities
        Administration Account on the Master Servicer Remittance Date, any monies
        remitted by the Master Servicer to the Securities Administrator on such date
        pursuant to the terms of this Agreement.

       

      (f) The
        Securities Administrator may invest, or cause to be invested, funds held
        in the
        Securities Administration Account, which funds, if invested, shall be invested
        in Eligible Investments (which may be obligations of the Securities
        Administrator or its Affiliate). All such investments must be payable on
        demand
        or mature no later than the next Deposit Date, and shall not be sold or disposed
        of prior to their maturity. All such Eligible Investments will be made in
        the
        name of the Trustee (in its capacity as such) or its nominee. All income
        and
        gain realized from any such investment for each Distribution Date shall be
        compensation (1) to the Trustee, in payment of its Trustee Fee, to the extent
        not paid when due in accordance with Section 6.12, (2) to the Custodian, in
        payment of its Custodial Compensation, to the extent not paid when due in
        accordance with Section 6.12 and (3) to the Securities Administrator, any
        income
        and gain remaining. The Securities Administrator shall pay to the Trustee
        the
        Trustee Fee and the Custodian its Custodial Compensation on behalf of the
        Trust
        Fund and all income and gain realized from any such investments shall be
        subject
        to its withdrawal on order from time to time. The amount of any losses incurred
        in respect of any such investments shall be paid by the Securities Administrator
        for deposit in the Securities Administration Account out of its own funds,
        without any right of reimbursement therefor, immediately as
        realized.

                  5.01

              	
                Distributions
                  Generally. 

              

      

       

      (a) Subject
        to Section 7.01 respecting the final distribution on the Certificates or
        Lower
        Tier REMIC 1 Uncertificated Regular Interests, on each Distribution Date
        the
        Trustee or the Paying Agent shall make allocations and/or distributions in
        accordance with the Preliminary Statement and this Article V and based solely
        on
        the reports for such Distribution Date provided to it by the Securities
        Administrator pursuant to Section 4.03(a). Such distributions shall be made
        by
        wire transfer in immediately available funds to an account specified in writing
        to the Trustee at least five (5) Business Days prior to the first Distribution
        Date to such Certificateholder and at the expense of such
        Certificateholder.

      (b) The
        final
        distribution in respect of any Certificate shall be made only upon presentation
        and surrender of such Certificate at the Corporate Trust Office; provided,
        however,
        that
        the foregoing provisions shall not apply to any Class of Certificates as
        long as
        such Certificate remains a Book-Entry Certificate in which case all payments
        made shall be made through the Clearing Agency and its Clearing Agency
        Participants. Notwithstanding such final payment of principal of any of the
        Certificates, each Residual Certificate will remain outstanding until the
        termination of each REMIC and the payment in full of all other amounts due
        with
        respect to the Residual Certificates and at such time such final payment
        in
        retirement of any Residual Certificate will be made only upon presentation
        and
        surrender of such Certificate at the Corporate Trust Office. If any payment
        required to be made on the Certificates or Lower Tier REMIC 1 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. 

       

      (c) 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
        Class Principal Amounts (or Percentage Interests).

       

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

        Trustee) shall withdraw from the Certificate Account the Total Distribution
        Amount (to the extent such amount is on deposit in the Certificate Account),
        and
        amounts that are available for payment to the Swap Counterparty, and shall
        allocate such amount to the interests issued in respect of each REMIC created
        pursuant to this Agreement and shall distribute such amount as specified
        in
        subparagraphs (b) through (i) of this Section 5.02; provided,
        that

        paid on
        the related Swap Payment Date. On each Distribution Date after a Section
        7.01(c)
        Purchase Event but on or prior to a Trust Fund Termination Event, the Trustee
        (or the Paying Agent acting on behalf of the Trustee) shall withdraw from
        the
        Certificate Account the Total Distribution Amount (to the extent such amount
        is
        on deposit in the Certificate Account), and amounts that are available for
        payment to the Swap Counterparty, and shall allocate such amount to the

      (b) On
        each

                Advances
                  by Master Servicer, Servicers and Securities Administrator.
                  

              

      

       

      (a) Subject
        to Section 9.07, Advances shall be made in respect of each Master Servicer
        Remittance Date as provided herein. If, on any Determination Date, any Servicer
        determines that any Scheduled Payments (or in the case of Simple Interest
        Mortgage Loans, the amount of any scheduled interest payments) due during
        the
        related Collection Period (other than Balloon Payments) have not been received,
        such Servicer shall advance such amount to the extent provided in the applicable
        Servicing Agreement. If any Servicer fails to remit Advances required to
        be made
        under the applicable Servicing Agreement, the Master Servicer shall itself
        make,
        or shall cause the successor servicer to make, such Advance on the Master
        Servicer Remittance Date immediately following such Determination Date. 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 Securities Administrator from its own funds (or funds advanced
        by the applicable Servicer) for deposit in the Securities Administration
        Account
        immediately available funds in an amount equal to such Advance, (ii) cause
        to be
        made an appropriate entry in the records of the Collection Account that funds
        in
        such account being held for future distribution or withdrawal have been,
        as
        permitted by this Section 5.04, used by the Master Servicer to make such
        Advance, and remit such immediately available funds to the Securities
        Administrator for deposit in the Securities Administration Account or (iii)
        make
        Advances in the form of any combination of clauses (i) and (ii) aggregating
        the
        amount of such Advance. Any funds being held in the Collection Account for
        future distribution to Certificateholders and so used shall be replaced by
        the
        Master Servicer from its own funds by remittance to the Securities Administrator
        for deposit in the Securities Administration 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 rely conclusively 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. Notwithstanding anything to the contrary herein, in the
        event
        the Master Servicer determines in its reasonable judgment that an Advance
        is
        non-recoverable, the Master Servicer shall be under no obligation to make
        such
        Advance.

       

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

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

                Basis
                  Risk Reserve Fund. 

              

      

       

      (a) On
        the
        Closing Date, the Trustee shall establish and maintain in its name, in trust
        for
        the benefit of the Certificateholders, a Basis Risk Reserve Fund, into which
        Lehman Brothers Holdings Inc. (“LBH”) shall initially deposit $1,000. The Basis
        Risk Reserve Fund shall be an Eligible Account, and funds on deposit therein
        shall be held separate and apart from, and shall not be commingled with,
        any
        other monies, including, without limitation, other monies of the Trustee
        held
        pursuant to this Agreement.

       

      (b) The
        Trustee (or Paying Agent) shall make withdrawals from the Basis Risk Reserve
        Fund to make distributions pursuant to Section 5.02(f)(iv) hereof in accordance
        with the Distribution Date reports prepared by the Securities Administrator.
        Notwithstanding the foregoing, the initial deposit of $1,000 made pursuant
        to
        subsection (a) above may be applied by the Trustee (or Paying Agent) to make
        such distributions.

       

      (c) Funds
        in
        the Basis Risk Reserve Fund shall be invested in Eligible Investments. Any
        earnings on such amounts shall be distributed on each Distribution Date to
        the
        Holders of the Class X Certificates. The Class X Certificates shall evidence
        ownership of the Basis Risk Reserve Fund for federal income tax purposes
        and LBH
        on behalf of the Holder thereof shall direct the Trustee, in writing, as
        to
        investment of amounts on deposit therein. LBH shall be liable for any losses
        incurred on such investments. In the absence of written instructions from
        LBH as
        to investment of funds on deposit in the Basis Risk Reserve Fund, such funds
        shall be invested in the U.S. Bank First American Prime Obligation Fund,
        Class
        A. The Basis Risk Reserve Fund shall be terminated after the earlier of (A)
        a
        Section 7.01(c) Purchase Event or (B) a Trust Fund Termination Event and
        any
        funds remaining in such fund upon such termination shall be released to Holders
        of the Class X Certificates.

                Supplemental
                  Interest Trust. 

              

      

       

      (a) A
        separate trust is hereby established (the “Supplemental Interest Trust”), the
        corpus of which shall be held by the Trustee, in trust, for the benefit of
        the
        Certificateholders and the Swap Counterparty. The Trustee, as trustee of
        the
        Supplemental Interest Trust, shall establish an account (the “Swap Account”),
        into which LBH shall initially deposit $1,000. The Swap Account shall be
        an
        Eligible Account, and funds on deposit therein shall be held separate and
        apart
        from, and shall not be commingled with, any other monies, including, without
        limitation, other monies of the Trustee held pursuant to this Agreement.
        After
        payment in full to the Swap Counterparty of any Net Swap Payments or Swap
        Termination Payments owed to it pursuant to the Swap Agreement, any funds
        remaining in such fund upon termination of the Swap Account shall be released
        to
        Holders of the Class X Certificates pursuant to Sections 5.02(g)(xi) and
        5.02(g)(xii).

       

      
        
          
          

        

        
          111

          
            

          

        

        
          
          

        

      

      (b) In
        addition, the Trustee, as trustee of the Supplemental Interest Trust, shall
        establish an account (the “Interest Rate Cap Account”), into which LBH shall
        initially deposit $1,000. The Interest Rate Cap Account shall be an Eligible
        Account, and funds on deposit therein shall be held separate and apart from,
        and
        shall not be commingled with, any other monies, including, without limitation,
        other monies of the Trustee held pursuant to this Agreement.

       

      (c) In
        addition, on the Closing Date, the Trustee, on behalf of the Supplemental
        Interest Trust, shall establish an account (the “Collateral Account”) into which
        funds shall be deposited pursuant to Section 5.07(h). The Collateral Account
        shall be an Eligible Account, and funds on deposit therein shall be held
        separate and apart from, and shall not be commingled with, any other monies,
        including, without limitation, other monies of the Trustee held pursuant
        to this
        Agreement.

       

      (d) The
        Trustee shall deposit into the Swap Account any Net Swap Payment required
        pursuant to Sections 5.02(b), (c), (e) and (j), any Swap Termination Payment
        required pursuant to Sections 5.02(b), (c), (e) and (j), any amounts received
        from the Swap Counterparty under the Swap Agreement and any amounts distributed
        from the Basis Risk Reserve Fund required pursuant to Sections 5.02(f)(iv)(C)
        and (f)(vi), and shall distribute from the Swap Account any Net Swap Payment
        required pursuant to Section 5.02(g)(i) or Section 5.02(k), as applicable,
        or
        Swap Termination Payment required pursuant to Section 5.02(g)(ii), Section
        5.02(g)(x) or Section 5.02(k), as applicable. Notwithstanding
        the foregoing, the initial deposit of $1,000 made pursuant to subsection
        (a)
        above may be applied by the Trustee to make such distributions of any Net
        Swap
        Payment or any Swap Termination Payment.

       

      (e) The
        Trustee shall deposit into the Interest Rate Cap Account any amounts received
        from the Cap Counterparty under the Interest Rate Cap Agreement and shall
        distribute from the Interest Rate Cap Account any Interest Rate Cap Amount
        pursuant to Section 5.02(h) or Section 5.02(l), as applicable.

       

      (f) Funds
        in
        the Swap Account shall be invested in Eligible Investments. Any earnings
        on such
        amounts shall be distributed on each Distribution Date pursuant to Section
        5.02(g) or Section 5.02(k), as applicable. The Class X Certificates shall
        evidence ownership of the Swap Account for federal income tax purposes and
        the
        Holder thereof shall direct the Trustee, in writing, as to investment of
        amounts
        on deposit therein. LBH shall be liable for any losses incurred on such
        investments. In the absence of written instructions from the Class X
        Certificateholders as to investment of funds on deposit in the Swap Account,
        such funds shall be invested in the U.S. Bank First American Government
        Obligations Fund, Class A or comparable investment vehicle. Any amounts on
        deposit in the Swap Account in excess of the Swap Amount on any Distribution
        Date shall be held for distribution pursuant to Section 5.02(g) or Section
        5.02(k), as applicable, on the following Distribution Date.

      (g) Funds
        in
        the Interest Rate Cap Account shall be invested in Eligible Investments.
        Any
        earnings on such amounts shall be distributed on each Distribution Date pursuant
        to Section 5.02(h) or Section 5.02(l), as applicable. The Class X Certificates
        shall evidence ownership of the Interest Rate Cap Account for federal income
        tax
        purposes and the Holder thereof shall direct the Trustee, in writing, as
        to
        investment of amounts on deposit therein. LBH shall be liable for any losses
        incurred on such investments. In the absence of written instructions from
        the
        Class X Certificateholders as to investment of funds on deposit in the Interest
        Rate Cap Account, such funds shall be invested in the U.S. Bank First American
        Government Obligations Fund, Class A or comparable investment vehicle. Any
        amounts on deposit in the Interest Rate Cap Account in excess of the Interest
        Rate Cap Amount on any Distribution Date shall be held for distribution pursuant
        to Section 5.02(h) or Section 5.02(l), as applicable, on the following
        Distribution Date.

       

      (h) Funds
        or
        collateral required to be held pursuant to the Credit Support Annex shall
        be
        deposited into the Collateral Account. Funds posted by the Cap Counterparty
        (or
        its credit support provider) and/or the Swap Counterparty (or its credit
        support
        provider) in the Collateral Account shall be invested in Eligible Investments.
        Any interest earnings on such amounts shall be remitted to the Cap Counterparty
        and/or Swap Counterparty, as applicable, pursuant to the terms of the Credit
        Support Annex. For federal income tax purposes, the Swap Counterparty shall
        be
        considered the owner of funds deposited in the Collateral Account on account
        of
        the Swap Agreement, and the Cap Counterparty shall be considered the owner
        of
        the funds deposited in the Collateral Account on account of the Interest
        Rate
        Cap Agreement, and each shall direct the Trustee, in writing, as to investment
        of the applicable amounts on deposit therein. The Trustee shall not be liable
        for any losses incurred on such investments. In the absence of written
        instructions from the Cap Counterparty (or its credit support provider) and/or
        the Swap Counterparty (or its credit support provider) as to investment of
        funds
        on deposit in the Collateral Account, such funds shall be invested in the
        U.S.
        Bank First American Government Obligations Fund, Class A or comparable
        investment vehicle. On the first Distribution Date immediately following
        any
        Swap Payment Date as to which a shortfall exists with respect to a Net Swap
        Payment or a Swap Termination Payment owed by the Swap Counterparty as a
        result
        of its failure to make payments pursuant to the Swap Agreement, amounts
        necessary to cover such shortfall shall be removed from the Collateral Account,
        remitted to the Swap Account and distributed as all or a portion of such
        Net
        Swap Payment or Swap Termination Payment pursuant to Section 5.02(g) or Section
        5.02(k), as applicable. On any Distribution Date as to which a shortfall
        exists
        with respect to Interest Rate Cap Amounts owed by the Cap Counterparty as
        a
        result of its failure to make payments pursuant to the Interest Rate Cap
        Agreement, amounts necessary to cover such shortfall shall be removed from
        the
        Collateral Account, remitted to the Interest Rate Cap Account and distributed
        as
        all or a portion of such Interest Rate Cap Amount pursuant to Section 5.02(h)
        or
        Section 5.02(l), as applicable. Any amounts on deposit in the Collateral
        Account
        required to be returned to the Cap Counterparty (or its credit support provider)
        and/or the Swap Counterparty (or its credit support provider), as applicable,
        as
        a result of (i) the termination of the Swap Agreement or Interest Rate Cap
        Agreement, as applicable, (ii) the procurement of a guarantor, (iii) the
        reinstatement of required ratings or (iv) otherwise pursuant to the Swap
        Agreement, shall be released directly to the Swap Counterparty and/or the
        Cap
        Counterparty, as applicable, pursuant to the terms of the Credit Support
        Annex.

      (i) Upon
        termination of the Trust Fund, any amounts remaining in the Swap Account
        shall
        be distributed pursuant to the priorities set forth in Section 5.02(g) or
        Section 5.02(k), as applicable.

       

      (j) Upon
        termination of the Trust Fund, any amounts remaining in the Interest Rate
        Cap
        Account shall be distributed pursuant to the priorities set forth in Section
        5.02(h) or Section 5.02(l), as applicable.

       

      (k) Upon
        termination of the Trust Fund, any amounts remaining in the Collateral Account
        shall be distributed as required pursuant to the terms of the Credit Support
        Annex.

       

      (l) It
        is the
        intention of the parties hereto that, for federal and state income and state
        and
        local franchise tax purposes, the Supplemental Interest Trust be disregarded
        as
        an entity separate from the holder of the Class X Certificates unless and
        until
        the date when either (a) there is more than one Class X Certificateholder
        or (b)
        any Class of Certificates in addition to the Class X Certificates is
        recharacterized as an equity interest in the Supplemental Interest Trust
        for
        federal income tax purposes. Neither the Securities Administrator nor the
        Trustee shall be responsible for any entity level tax reporting for the
        Supplemental Interest Trust.

       

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

       

      (n) In
        the
        event that either the Swap Counterparty or the Cap Counterparty fails to
        perform
        any of its obligations under the Swap Agreement or the Interest Rate Cap
        Agreement, respectively (including, without limitation, its obligations to
        make
        any payment or transfer collateral), or breaches any of its representations
        and
        warranties under the Swap Agreement or the Interest Rate Cap Agreement, as
        applicable, or in the event that an Event of Default, Termination Event,
        or
        Additional Termination Event occurs (as such terms are defined in the Swap
        Agreement or the Interest Rate Cap Agreement, as applicable), the Securities
        Administrator or the Trustee, on behalf of the Supplemental Interest Trust,
        shall (upon a Responsible Officer of the Securities Administrator or the
        Trustee
        receiving written notice or obtaining actual knowledge of the occurrence
        thereof), as soon as practicable following such written notice or obtaining
        knowledge, notify the Swap Counterparty or Cap Counterparty, as applicable,
        and
        give any notice of such failure and make any demand for payment pursuant
        to the
        Swap Agreement or Interest Rate Cap Agreement, as applicable. In the event
        that
        the Swap Counterparty’s obligations under the Swap Agreement or Cap
        Counterparty’s obligations under the Interest Rate Cap Agreement are at any time
        guaranteed by a third party, then to the extent that the Swap Counterparty
        or

                  of Swap Counterparty. 

              

      

       

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

       

      
        	
                Section
                  5.09

              	
                Termination
                  Receipts. 

              

      

       

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

       

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

      Amounts
        on deposit in the Swap Replacement Receipts Account shall be held for the
        benefit of the related Swap Counterparty and paid to such Swap Counterparty
        if
        the Supplemental Interest Trust is required to make a payment to such Swap
        Counterparty following an event of default or termination event with respect
        to
        the Supplemental Interest Trust under the related Swap Agreement. Any amounts
        not so applied shall, following the termination or expiration of such
        replacement swap agreement, be paid to the Class X Certificates.

       

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

       

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

      CONCERNING
        THE TRUSTEE AND THE SECURITIES ADMINISTRATOR; EVENTS OF DEFAULT

       

      
        	
                Section
                  6.01

              	
                Duties
                  of Trustee and Securities Administrator.

              

      

       

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

       

      
        
          
          

        

        
          116

          
            

          

        

        
          
          

        

      

      (b) Each
        of
        the Trustee and the Securities Administrator, upon receipt of all resolutions,
        certificates, statements, opinions, reports, documents, orders or other
        instruments furnished to the Trustee or the Securities Administrator, as
        applicable, 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
        neither the Trustee nor the Securities Administrator shall be responsible
        for
        the accuracy or content of any such resolution, certificate, statement, opinion,
        report, document, order or other instrument furnished by the Master Servicer,
        any Servicer, the Swap Counterparty, the Cap Counterparty or the Credit Risk
        Manager to the Trustee or the Securities Administrator pursuant to this
        Agreement, and shall not be required to recalculate or verify any numerical
        information furnished to the Trustee or the Securities Administrator 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 or Securities Administrator, as
        applicable, 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 or Securities Administrator’s,
        as applicable, satisfaction, the Trustee or Securities Administrator, as
        applicable, will provide notice thereof to the Certificateholders and any
        NIMS
        Insurer and will, at the expense of the Trust Fund, which expense shall be
        reasonable given the scope and nature of the required action, take such further
        action as directed by the Certificateholders and any NIMS Insurer.

       

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

       

      (i)
         Neither
        the Trustee nor the Securities Administrator shall 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 Corporate Trust Office, and such
        notice references the Holders of the Certificates and this
        Agreement;

       

      
        
          
          

        

        
          117

          
            

          

        

        
          
          

        

      

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

       

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

       

      (v)
         Neither
        the Trustee nor the Securities Administrator shall be responsible for any
        act or
        omission of the Master Servicer, any Servicer, the Credit Risk Manager, the
        Depositor, the Seller, the Custodian, the Swap Counterparty or the Cap
        Counterparty and neither the Securities Administrator nor the Trustee shall
        be
        responsible for any act or omission of the other.

       

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

       

      (e) Neither
        the Trustee nor the Securities Administrator shall be personally liable with
        respect to any action taken, suffered or omitted to be taken by it in good
        faith
        in accordance with the direction of any NIMS Insurer or the Certificateholders
        of any Class holding Certificates which evidence, as to such Class, Percentage
        Interests aggregating not less than 25% as to the time, method and place
        of
        conducting any proceeding for any remedy available to the Trustee or the
        Securities Administrator or exercising any trust or power conferred upon
        the
        Trustee or the Securities Administrator, as applicable, under this
        Agreement.

       

      (f) Neither
        the Trustee nor the Securities Administrator shall be 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 or the Securities Administrator, as
        applicable, 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 Securities
        Administrator shall be the successor to, and be vested with the rights, duties,
        powers and privileges of, the Master Servicer in accordance with the terms
        of
        this Agreement.

      (g) The
        Trustee shall not be held liable by reason of any insufficiency in the
        Collection Account or any other account established under this Agreement
        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 shall not and, except as otherwise provided herein, the Securities
        Administrator 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 Collection Account, the Securities Administration Account
        or
        the Certificate Account, as applicable. Except as otherwise provided herein,
        neither the Trustee nor the Securities Administrator shall have any duty to
        confirm or verify the contents of any reports or certificates of the Master
        Servicer, any Servicer, the Swap Counterparty, the Cap Counterparty or the
        Credit Risk Manager delivered to the Trustee or the Securities Administrator
        pursuant to this Agreement believed by the Trustee or the Securities
        Administrator, as applicable, to be genuine and to have been signed or presented
        by the proper party or parties.

       

      (i) Neither
        the Securities Administrator nor the Trustee shall be liable in its individual
        capacity for an error of judgment made in good faith by a Responsible Officer
        or
        other officers of the Trustee or the Securities Administrator, as applicable,
        unless it shall be proved that the Trustee or the Securities Administrator,
        as
        applicable, was negligent in ascertaining the pertinent facts.

       

      (j) Notwithstanding
        anything in this Agreement to the contrary, none of the Securities
        Administrator, any Paying Agent or the Trustee shall be liable for special,
        indirect or consequential losses or damages of any kind whatsoever (including,
        but not limited to, lost profits), even if the Securities Administrator,
        the
        Paying Agent or the Trustee, as applicable, has been advised of the likelihood
        of such loss or damage and regardless of the form of action, provided,
        however,
        that

        shall
        give prior written notice to the Sponsor, the Master Servicer and the Depositor
        of the appointment of any Subcontractor by it and a written description (in
        form
        and substance satisfactory to the Sponsor and the Depositor) of the role
        and

        to the Trustee or the Securities Administrator by the security afforded to
        it by

        the
        resigning Trustee or resigning Securities Administrator, as applicable, may

        either of their property or affairs for the purpose of rehabilitation,
        conservation or liquidation, (iii) the Securities Administrator shall fail
        to
        observe or perform in any material respect any of the covenants or agreements
        of
        the Securities Administrator contained in this Agreement, including (A) any
        failure to remit payment to the Trustee on the Deposit Date which failure
        continues unremedied for a period of one Business Day (unless such failure
        to
        remit payment is directly caused by a failure by the Master Servicer to remit
        payments to the Securities Administrator and the Trustee has not terminated
        the
        Master Servicer as a result of such failure to remit, in which case the
        Securities Administrator shall remit payment as promptly as possible, but
        in no
        case later than one Business Day after recovering payment from the Master
        Servicer) and (B) any failure to provide the information, reports, assessments
        or attestations required pursuant to Subsection 9.25(a) or 9.25(b) hereof,

        a tax is imposed or threatened with respect to the Trust Fund by any state
        in
        which the Trustee or the Trust Fund held by the Trustee is located, (v) the

        delivered to the Depositor, one copy to the Trustee, one copy each to the
        Master
        Servicer and any NIMS Insurer; the Depositor shall thereupon appoint a successor
        trustee or successor securities administrator, as applicable, in accordance
        with
        this Section mutually acceptable to the Depositor, the Master Servicer and
        any

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

       

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

       

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

      (d) Upon
        the
        resignation or removal of the Trustee pursuant to this Section 6.06, the
        Trustee
        shall deliver the amounts held in its possession for the benefit of the
        Certificateholders to the successor trustee upon the appointment of the
        successor trustee.

                  of Co-Trustee, Separate Trustee or Custodian.
                  

              

      

       

      (a) Notwithstanding
        any other provisions hereof, at any time, the Trustee, the Depositor or the
        Certificateholders evidencing more than 50% of the Class Principal Amount
        (or
        Percentage Interest) of every Class of Certificates shall
        have the power from time to time to appoint one or more Persons, approved
        by the
        Trustee and any NIMS Insurer, to act either as co-trustees jointly with the
        Trustee, or as separate trustees, or as custodians, for the purpose of holding
        title to, foreclosing or otherwise taking action with respect to any Mortgage
        Loan outside the state where the Trustee has its principal place of business
        where such separate trustee or co-trustee is necessary or advisable (or the
        Trustee has been advised by the Master Servicer that such separate trustee
        or
        co-trustee is necessary or advisable) under the laws of any state in which
        a
        property securing a Mortgage Loan is located or for the purpose of otherwise
        conforming to any legal requirement, restriction or condition in any state
        in
        which a property securing a Mortgage Loan is located or in any state in which
        any portion of the Trust Fund is located. The separate Trustees, co-trustees,
        or
        custodians so appointed shall be trustees or custodians for the benefit of
        all
        the Certificateholders and shall have such powers, rights and remedies as
        shall
        be specified in the instrument of appointment; provided,
        however,
        that no
        such appointment shall, or shall be deemed to, constitute the appointee an
        agent
        of the Trustee. The obligation of the Securities Administrator 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 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;

       

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

       

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

       

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

       

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

        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.

                  Agents. 

              

      

       

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

       

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

       

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

      Each

        any
        legal proceeding or incurred without negligence or willful misconduct on
        their
        part (it being understood that the negligence or willful misconduct of any
        Custodian shall not constitute negligence or willful misconduct on the part
        of
        the Trustee or any of its directors, officers, employees or agents for such
        purpose) arising out of, or in connection with, the acceptance or administration
        of the trusts created hereunder or in connection with the performance of
        its
        duties hereunder or under the Swap Agreement, the Interest Rate Cap Agreement,
        the Mortgage Loan Sale Agreement, the Transfer Agreement, any Servicing
        Agreement, the MGIC Letter Agreement, the PMI Letter Agreement or the Custodial
        Agreement, including any applicable fees and expenses payable pursuant to
        Section 6.12 and the costs and expenses of defending themselves against any
        claim in connection with the exercise or performance of any of their powers
        or
        duties hereunder, provided that:

       

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

       

      (ii)
         while
        maintaining control over its own defense, the Trustee or the Securities
        Administrator, as applicable, shall cooperate and consult fully with the
        Depositor, the Master Servicer and any NIMS Insurer in preparing such defense;
        and

       

      (iii)
         notwithstanding
        anything to the contrary in this Section 6.11, the Trust Fund shall not be
        liable for settlement of any such claim by the Trustee or the Securities
        Administrator, as applicable, entered into without the prior consent of the
        Depositor, the Master Servicer and any NIMS Insurer, 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 fifth 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 or the Securities Administrator,
        as applicable, and shall be construed to include, but not be limited to any
        loss, liability or expense under any environmental law.

        and
        the Securities Administrator shall be entitled to reimbursement of all
        reasonable expenses, disbursements and advances incurred or made by the
        Securities Administrator or Trustee, as applicable, 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
        such party 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. If either the Trustee Fee
        or
        the Custodial Compensation is not fully paid from (i) the Securities
        Administrator’s own funds or (ii) investment income and earnings on amounts on
        deposit in the Securities Administration Account or the Certificate Account,
        as
        applicable, then prior to any distribution to Certificateholders pursuant
        to
        Section 5.02 hereof, the Trust Fund shall immediately reimburse the Trustee,
        or
        the Custodian, as applicable, upon demand for any such shortfall from amounts
        on
        deposit in the Certificate Account. To the extent required under Section
        20 of
        the Custodial Agreement, the Trustee is hereby authorized to pay any
        indemnification amounts from amounts on deposit in the Certificate Account
        prior
        to any distributions to Certificateholders pursuant to Section 5.02 hereof.

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

        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

      (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

        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,
        any
        NIMS Insurer 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
        Fannie Mae- or Freddie Mac -approved servicer within 60 days of the date
        the
        Master Servicer receives such notice or acquires such actual knowledge;
        or

       

      (xii)
         After

        Insurer, any failure of the Master Servicer to remit to the Securities
        Administrator any payment required to be made to the Securities Administrator
        for the benefit of Certificateholders under the terms of this Agreement,
        including any Advance, on any Master Servicer Remittance 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 (xii) 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 (with a copy to the Securities Administrator) 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 (with a copy to the Securities
        Administrator), shall promptly terminate all of the rights and obligations
        of
        the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds
        thereof. On or after the receipt by the Master Servicer of such written notice,
        all authority and power of the Master Servicer, and only in its capacity
        as
        Master Servicer under this Agreement, whether with respect to the Mortgage
        Loans
        or otherwise, shall pass to and be vested in the Securities Administrator
        and
        upon receipt of written notice by the Securities Administrator from the Trustee
        pursuant to and under the terms of this Agreement; provided,
        however,
        the
        parties acknowledge that notwithstanding the preceding sentence there may
        be a
        transition period, not to exceed 90 days, in order to effect the transfer
        of the
        Master Servicing obligations to the Securities Administrator; provided,
        further,
        the
        obligation to make Advances by the Securities Administrator shall be effective
        upon the Trustee providing notice to the Securities Administrator of the
        termination of the Master Servicer pursuant to this Section 6.14. The Securities
        Administrator is hereby authorized and empowered to execute and deliver,
        on
        behalf of the defaulting Master Servicer as attorney-in-fact or otherwise,
        any
        and all documents and other instruments, and to do or accomplish all other
        acts
        or things necessary or appropriate to effect the purposes of such notice
        of
        termination, whether to complete the transfer and endorsement or assignment
        of
        the Mortgage Loans and related documents or otherwise. The defaulting Master
        Servicer agrees to cooperate with the Trustee and the Securities Administrator
        in effecting the termination of the defaulting Master Servicer’s
        responsibilities and rights hereunder as Master Servicer including, without
        limitation, notifying the Servicers of the assignment of the master servicing
        function and providing the Securities Administrator or its designee all
        documents and records in electronic or other form reasonably requested by
        it to
        enable the Securities Administrator or its designee to assume the defaulting
        Master Servicer’s functions hereunder and the transfer to the Securities
        Administrator for administration by it of all amounts which shall at the
        time be
        or should have been deposited by the defaulting Master Servicer in the
        Collection Account maintained by such defaulting Master Servicer and any
        other
        account or fund maintained with respect to the Certificates or thereafter
        received with respect to the Mortgage Loans. The Master Servicer being
        terminated (or the Trust Fund, if the Master Servicer is unable to fulfill
        its
        obligations hereunder) as a result of an Event of Default shall bear all
        costs
        of a master servicing transfer, including but not limited to those of the
        Trustee or Securities Administrator reasonably allocable to specific employees
        and overhead, legal fees and expenses, accounting and financial consulting
        fees
        and expenses, and costs of amending the Agreement, if necessary.

       

      
        
          
          

        

        
          131

          
            

          

        

        
          
          

        

      

      The
        Securities Administrator and 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 Securities Administrator to correct
        any
        errors or insufficiencies in the master servicing data or otherwise to enable
        the Securities Administrator to master service the Mortgage Loans properly
        and
        effectively. If the terminated Master Servicer does not pay such reimbursement
        within thirty (30) days of its receipt of an invoice therefor, such
        reimbursement shall be an expense of the Trust Fund and the Securities
        Administrator and the Trustee, as applicable, shall be entitled to withdraw
        such
        reimbursement from amounts on deposit in the Certificate Account pursuant
        to
        Section 4.04(b); provided that the terminated Master Servicer shall reimburse
        the Trust Fund for any such expense incurred by the Trust Fund; and provided,
        further, that the Securities Administrator 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.

       

      
        
          
          

        

        
          132

          
            

          

        

        
          
          

        

      

      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 Securities Administrator or the Trustee,
        upon
        a Responsible Officer of such party becoming aware of the occurrence thereof,
        shall promptly notify the Securities Administrator, the Trustee, any NIMS
        Insurer, the Swap Counterparty, the Cap Counterparty, and each Rating Agency
        of
        the nature and extent of such Event of Default. The Securities Administrator
        shall immediately give written notice to the Master Servicer and the Trustee
        upon the Master Servicer’s failure to remit funds to the Securities
        Administrator 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
        and within a period of time not to exceed 90 days after the Securities
        Administrator receives written notice from the Trustee pursuant to Section
        6.14(a) or Section 9.28, the Securities Administrator, unless another master
        servicer shall have been appointed, shall be the successor in all respects
        to
        the Master Servicer in its capacity as such under this Agreement and the
        transactions set forth or provided for herein and shall have all the rights
        and
        powers and be subject to all the responsibilities, duties and liabilities
        relating thereto and arising thereafter placed on the Master Servicer hereunder,
        including the obligation to make Advances; provided,
        however,
        that
        any failure to perform such duties or responsibilities caused by the Master
        Servicer’s or the Trustee’s failure to provide information required by this
        Agreement shall not be considered a default by the Securities Administrator
        or
        the Trustee hereunder. In addition, the Securities Administrator shall have
        no
        responsibility for any act or omission of the Master Servicer prior to the
        issuance of any notice of termination and within a period of time not to
        exceed
        90 days after the Securities Administrator receives written notice from the
        Trustee pursuant to Section 6.14(a) or Section 9.28, as applicable. The
        Securities Administrator shall have no liability relating to the representations
        and warranties of the Master Servicer set forth in Section 9.14. In the
        Securities Administrator’s capacity as such successor, the Securities
        Administrator shall have the same limitations on liability herein granted
        to the
        Master Servicer. As compensation therefor, the Securities Administrator shall
        be
        entitled to receive all compensation payable to the Master Servicer under
        this
        Agreement, including the Master Servicing Fee.

       

      
        
          
          

        

        
          133

          
            

          

        

        
          
          

        

      

      (c) Notwithstanding
        the above, the Securities Administrator may, if it shall be unwilling to
        continue to so act, or shall, if it is unable to so act, request the Trustee
        to
        appoint, petition a court of competent jurisdiction to appoint, or appoint
        on
        its own behalf any established housing and home finance institution servicer,
        master servicer, servicing or mortgage servicing institution having a net
        worth
        of not less than $15,000,000 and meeting such other standards for a successor
        master servicer as are set forth in this Agreement, as the successor to such
        Master Servicer in the assumption of all of the responsibilities, duties
        or
        liabilities of the Master Servicer hereunder. Such successor master servicer
        shall have no responsibility for any act or omission of the Master Servicer
        prior to such successor’s assumption of the Master Servicer’s rights and
        obligations hereunder and such successor master servicer shall also have
        no
        liability relating to the representations and warranties of the Master Servicer
        set forth in Section 9.14. Any entity designated by the Trustee or the
        Securities Administrator as a successor master servicer may be an Affiliate
        of
        the Trustee or the Securities Administrator; provided,
        however,
        that,
        unless such Affiliate meets the net worth requirements and other standards
        set
        forth herein for a successor master servicer, the Trustee or the Securities
        Administrator, in its individual capacity shall agree, at the time of such
        designation, to be and remain liable to the Trust Fund for such Affiliate’s
        actions and omissions in performing its duties hereunder. In connection with
        such appointment and assumption, the Trustee or the Securities Administrator
        may
        make such arrangements for the compensation of such successor out of payments
        on
        Mortgage Loans as it and such successor shall agree; provided,
        however,
        that no
        such compensation shall be in excess of that permitted to the Master Servicer
        hereunder. The Trustee, the Securities Administrator and such successor shall
        take such actions, consistent with this Agreement, as shall be necessary
        to
        effectuate any such succession and may make other arrangements with respect
        to
        the servicing to be conducted hereunder which are not inconsistent herewith.
        The
        Master Servicer shall cooperate with the Trustee, the Securities Administrator
        and any successor master servicer in effecting the termination of the Master
        Servicer’s responsibilities and rights hereunder including, without limitation,
        notifying Mortgagors of the assignment of the master servicing functions
        and
        providing the Trustee, the Securities Administrator and successor master
        servicer, as applicable, all documents and records in electronic or other
        form
        reasonably requested by it to enable it to assume the Master Servicer’s
        functions hereunder and the transfer to the Trustee, the Securities
        Administrator or such successor master servicer, as applicable, all amounts
        which shall at the time be or should have been deposited by the Master Servicer
        in the Collection Account and any other account or fund maintained with respect
        to the Certificates or the Lower Tier REMIC 1 Uncertificated Regular Interests
        or thereafter be received with respect to the Mortgage Loans. Neither the
        Trustee, the Securities Administrator nor any other successor master servicer
        shall be deemed to be in default hereunder by reason of any failure to make,
        or
        any delay in making, any distribution hereunder or any portion thereof caused
        by
        (i) the failure of the Master Servicer to deliver, or any delay in delivering,
        cash, documents or records to it, (ii) the failure of the Master Servicer
        to
        cooperate as required by this Agreement, (iii) the failure of the Master
        Servicer to deliver the Mortgage Loan data to the Securities Administrator
        as
        required by this Agreement or (iv) restrictions imposed by any regulatory
        authority having jurisdiction over the Master Servicer. Neither the Securities
        Administrator nor any other successor master servicer shall be deemed to
        be in
        default hereunder by reason of any failure to make, or any delay in making,
        any
        distribution hereunder or any portion thereof caused by (i) the failure of
        the
        Trustee to deliver, or any delay in delivering cash, documents or records
        to it,
        or (ii) the failure of Trustee to cooperate as required by this Agreement.

      During

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

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

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

      Subject

        limitation, (i) the conducting or defending of any administrative action

        Certificateholders or any NIMS Insurer, unless such Certificateholders or
        any
        NIMS Insurer shall have offered to the Trustee reasonable security or indemnity
        against the cost, expenses and liabilities which may be incurred therein
        or
        thereby; and, provided further, that, subject to the provisions of Section
        8.01,
        the Trustee shall have the right to decline to follow any such direction
        if the
        Trustee, in accordance with an Opinion of Counsel acceptable to any NIMS
        Insurer, 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.

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

       

      (b) The
        Securities Administrator 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 Securities Administrator
        shall also file a Form 8811 as required. The Securities Administrator, 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 Trustee
        and 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 Securities Administrator shall, in accordance with
        industry standards and the rules of the Commission as in effect from time
        to
        time (the “Rules”), prepare and file with the Commission via the Electronic Data
        Gathering and Retrieval System (“EDGAR”), the reports listed in subsections (d)
        through (g) of this Section 6.20 in respect of the Trust Fund as and to the
        extent required under the Exchange Act.

       

      (d) Reports
        Filed on Form 10-D. 

       

      (i)
         Within
        15
        days after each Distribution Date (subject to permitted extensions under
        the
        Exchange Act), the Securities Administrator 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 Securities Administrator shall file
        each
        Form 10-D with a copy of the related Distribution Date Statement and a copy
        of
        each report made available by the Credit Risk Manager pursuant to Section
        9.34
        (provided each such report is made available to the Securities Administrator
        in
        a format compatible with EDGAR filing requirements) attached thereto. Any
        disclosure in addition to the Distribution Date Statement that is required
        to be
        included on Form 10-D (“Additional Form 10-D Disclosure”) shall be determined
        and prepared by and at the direction of the Depositor pursuant to the following
        paragraph and the Securities Administrator will have no duty or liability
        for
        any failure hereunder to determine or prepare any Additional Form 10-D
        Disclosure, except as set forth in the next paragraph.

       

      (ii)
         As
        set
        forth on Exhibit P-1 hereto, within five calendar days after the related
        Distribution Date, (A) certain parties to the BNC Mortgage Loan Trust 2007-1
        transaction shall be required to provide to the Depositor and the Securities
        Administrator, to the extent known by a responsible officer thereof, in
        EDGAR-compatible form (which may be Word or Excel documents easily convertible
        to EDGAR format), or in such other form as otherwise agreed upon by the
        Securities Administrator and such party, the form and substance of any
        Additional Form 10-D Disclosure, if applicable, and include with such Additional
        Form 10-D Disclosure an Additional Disclosure Notification in the form attached
        hereto as Exhibit P-4 and (B) the Depositor will approve, as to form and
        substance, or disapprove, as the case may be, the inclusion of the Additional
        Form 10-D Disclosure on Form 10-D. The Sponsor will be responsible for any
        reasonable fees and expenses assessed or incurred by the Securities
        Administrator in connection with including any Additional Form 10-D Disclosure
        on Form 10-D pursuant to this paragraph.

       

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

      (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.” Unless the Depositor has given the
        Securities Administrator prior notice as provided below, at the date of filing
        of each report on Form 10-D, the Depositor shall be deemed to represent to
        the
        Securities Administrator, as of such date, that 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
        Securities Administrator 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 Securities Administrator
        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)
         Unless
        and until a Form 15 suspension notice shall have been filed, within 90 days
        after the end of each fiscal year of the Trust Fund or such earlier date
        as may
        be required by the Exchange Act (the “10-K Filing Deadline”) (it being
        understood that the fiscal year for the Trust Fund ends on December
        31st
        of each
        year), commencing in March 2008, the Securities Administrator shall prepare
        and
        file on behalf of the Trust Fund a Form 10-K, in form and substance as required
        by the Exchange Act. Each such Form 10-K shall include the following items,
        in
        each case to the extent they have been delivered to the Securities Administrator

        Credit Risk Manager, any Servicing Function Participant, the Paying Agent
        and
        the Securities Administrator (each, a “Reporting Servicer”), as described under
        Section 9.25(a) hereof and in each Servicing Agreement and Custodial Agreement,
        and (II) if any Reporting Servicer’s report on assessment of compliance with
        servicing criteria described under Section 9.25(a) hereof or in each 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 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 Securities Administrator
        will have no duty or liability for any failure hereunder to determine or
        prepare
        any Additional Form 10-K Disclosure, except as set forth in the next paragraph.
        

       

      
        
          
          

        

        
          138

          
            

          

        

        
          
          

        

      

      (ii)
         As
        set
        forth on Exhibit P-2 hereto, no later than March 15 of each year that the
        Trust
        Fund is subject to the Exchange Act reporting requirements, commencing in
        2008,
        (A) certain parties to the BNC Mortgage Loan Trust 2007-1 transaction shall
        be
        required to provide to the Depositor and the Securities Administrator, to
        the
        extent known by a responsible officer thereof, in EDGAR-compatible form (which
        may be Word or Excel documents easily convertible to EDGAR format), or in
        such
        other form as otherwise agreed upon by the Securities Administrator and such
        party, the form and substance of any Additional Form 10-K Disclosure, if
        applicable, and include with such Additional Form 10-K Disclosure, an Additional
        Disclosure Notification in the form attached hereto as Exhibit P-4 and (B)
        the
        Depositor will approve, as to form and substance, or disapprove, as the case
        may
        be, the inclusion of the Additional Form 10-K Disclosure on Form 10-K. The
        Securities Administrator has no duty under this Agreement to monitor or enforce
        the performance by the parties listed on Exhibit P-2 of their duties under
        this
        paragraph or proactively solicit or procure from such parties any Form 10-K
        Disclosure Information. The Sponsor will be responsible for any reasonable
        fees
        and expenses assessed or incurred by the Securities Administrator in connection
        with including any Additional Form 10-K Disclosure on Form 10-K pursuant
        to this
        paragraph. 

       

      
        
          
          

        

        
          139

          
            

          

        

        
          
          

        

      

      (iii)
         After
        preparing the Form 10-K, the Securities Administrator 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 fourth
        Business Day prior to the 10-K Filing Deadline, a senior officer of the Exchange
        Act Signing Party shall sign the Form 10-K and return an electronic or fax
        copy
        of such signed Form 10-K (with an original executed hard copy to follow by
        overnight mail) to the Securities Administrator. If a Form 10-K cannot be
        filed
        on time or if a previously filed Form 10-K needs to be amended, the Securities
        Administrator will follow the procedures set forth in subsection (g) of this
        Section 6.20. Promptly (but no later than one Business Day) after filing
        with
        the Commission, the Securities Administrator will make available on its internet
        website a final executed copy of each Form 10-K prepared and filed by the
        Securities Administrator. The parties to this Agreement acknowledge that
        the
        performance by the Securities Administrator of its duties under this Section
        6.20(e) related to the timely preparation and filing of Form 10-K is contingent
        upon such parties (and any Additional Servicer or Servicing Function
        Participant) strictly observing all applicable deadlines in the performance
        of
        their duties under this Section 6.20(e), Section 9.25(a), Section 9.25(b)
        and
        Section 9.26. The Securities Administrator shall have no liability for any
        loss,
        expense, damage, claim arising out of or with respect to any failure to properly
        prepare and/or timely file such Form 10-K, where such failure results from
        the
        Securities Administrator’s inability or failure to obtain or receive, on a
        timely basis, any information from any other party hereto needed to prepare,
        arrange for execution or file such Form 10-K, not resulting from its own
        negligence, bad faith or willful misconduct.

       

      (iv)
         Each
        Form
        10-K shall include the Sarbanes-Oxley Certification. The Securities
        Administrator, the Paying Agent (if other than the Trustee) and the Trustee
        (including in its capacity as Paying Agent) and, if the Depositor is the
        Exchange Act Signing Party, the Master Servicer, shall, and the Securities
        Administrator, the Trustee (including in its capacity as Paying Agent), 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”), (x) in the
        case of the Master Servicer, in the form attached hereto as Exhibit Q-1,
        (y) in
        the case of the Securities Administrator, the form attached hereto as Exhibit
        Q-2, and (z) in the case of the Paying Agent or the Trustee (including in
        its
        capacity as Paying Agent), such other form as agreed to between such party
        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 Securities Administrator, the
        Trustee (including in its capacity as Paying Agent), 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.

       

      
        
          
          

        

        
          140

          
            

          

        

        
          
          

        

      

      (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.” Unless the Depositor has given the
        Securities Administrator prior notice as provided below, at the date of filing
        of each report on Form 10-K, the Depositor shall be deemed to represent to
        the
        Securities Administrator, as of such date, that 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
        Securities Administrator 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 Securities Administrator 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”) or such later date as may be
        required by the Commission, and if requested by the Depositor, the Securities
        Administrator shall prepare and file on behalf of the Trust Fund any Form
        8-K,
        as required by the Exchange Act; provided
        that the
        Depositor shall file the initial Form 8-K in connection with the issuance
        of the
        Certificates. Any disclosure or information related to a Reportable Event
        or
        that is otherwise required to be included on Form 8-K (“Form 8-K Disclosure
        Information”) shall be determined and prepared by and at the direction of the
        Depositor pursuant to the following paragraph and the Securities Administrator
        will have no duty or liability for any failure hereunder to determine or
        prepare
        any Form 8-K Disclosure Information or any Form 8-K, except as set forth
        in the
        next paragraph. 

       

      (ii)
         As
        set
        forth on Exhibit P-3 hereto, for so long as the Trust Fund is subject to
        the
        Exchange Act reporting requirements, no later than Noon New York City time
        on
        the second Business Day after the occurrence of a Reportable Event (A) certain
        parties to the BNC Mortgage Loan Trust 2007-1 transaction shall be required
        to
        provide to the Depositor and the Securities Administrator, to the extent
        known
        by a responsible officer thereof, in EDGAR-compatible form (which may be
        Word or
        Excel documents easily convertible to EDGAR format), or in such other form
        as
        otherwise agreed upon by the Securities Administrator and such party, the
        form
        and substance of any Form 8-K Disclosure Information, if applicable, and
        include
        with such Form 8-K Disclosure Information, an Additional Disclosure Notification
        in the form attached hereto as Exhibit P-4 and (B) the Depositor will approve,
        as to form and substance, or disapprove, as the case may be, the inclusion
        of
        the Form 8-K Disclosure Information. The Securities Administrator has no
        duty
        under this Agreement to monitor or enforce the performance by the parties
        listed
        on Exhibit P-3 of their duties under this paragraph or proactively solicit
        or
        procure from such parties any Form 8-K Disclosure Information. The Sponsor
        will
        be responsible for any reasonable fees and expenses assessed or incurred
        by the
        Securities Administrator in connection with including any Form 8-K Disclosure
        Information on Form 8-K pursuant to this paragraph. 

       

      
        
          
          

        

        
          141

          
            

          

        

        
          
          

        

      

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

       

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

       

      (i)
         On
        or
        before January 30 of the first year in which the Securities Administrator
        is
        able to do so under applicable law, unless otherwise directed by the Depositor,
        the Securities Administrator shall prepare and file a Form 15 relating to
        the
        automatic suspension of reporting in respect of the Trust Fund under the
        Exchange Act. The Paying Agent is entitled to assume that a Form 15 will
        be
        filed for such year unless the Securities Administrator notifies the Paying
        Agent that a Form 15 will not be filed.

       

      
        
          
          

        

        
          142

          
            

          

        

        
          
          

        

      

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

       

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

       

      (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 Securities
        Administrator, and such notice shall provide contact information for the
        Exchange Act Signing Party. If the Depositor and Master Servicer, at any
        time,
        mutually agree to change the identity of the Exchange Act Signing Party,
        the
        Depositor shall provide timely notice to the Securities Administrator of
        any
        such change. Any notice delivered pursuant to this Section 6.20 may be by
        fax or
        electronic copy notwithstanding the notice provisions of Section
        11.07.

        information, to the extent that such information is available or reasonably
        attainable within such time frame as may be requested, as the Sponsor, the
        Master Servicer, the Depositor or the Securities Administrator may determine
        in
        good faith is necessary to comply with the provisions of Regulation

      PURCHASE
        OF MORTGAGE LOANS AND

      TERMINATION
        OF THE TRUST FUND

       

      
        	
                Section
                  7.01

              	
                Purchase
                  of Mortgage Loans; Termination of Trust Fund Upon Purchase or Liquidation
                  of All Mortgage Loans; Purchase of Lower Tier REMIC 1 Uncertificated
                  Regular Interests. 

              

      

       

      (a) The
        respective obligations and responsibilities of the Trustee, the Securities
        Administrator and the Master Servicer created hereby (other than the obligation
        of the Trustee to make payments to Certificateholders and the Swap Counterparty
        as set forth in Section 7.02, the obligation of the Master Servicer to make
        a
        final remittance to the Securities Administrator pursuant to Section 4.01,
        the
        obligation of the Securities Administrator to make a final remittance to
        the
        Trustee pursuant to Section 4.05 and the obligations of the Master Servicer
        to
        the Securities Administrator pursuant to Section 9.10 and to the Securities
        Administrator and the Trustee pursuant to Sections 9.14 and 9.31) shall
        terminate on the earliest of (i) the final payment or other liquidation of
        the
        last Mortgage Loan remaining in the Trust Fund and the disposition of all
        REO
        Property, (ii) the sale of the property held by the Trust Fund in accordance
        with Section 7.01(b) and (iii) the Latest Possible Maturity Date (each, a
“Trust
        Fund Termination Event”); provided,
        however,
        that in
        no event shall the Trust Fund created hereby continue beyond the expiration
        of
        21 years from the death of the last survivor of the descendants of Joseph
        P.
        Kennedy, the late Ambassador of the United States to the Court of St. James’s,
        living on the date hereof. 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 on or after the Initial Optional Termination
        Date,
        the Master Servicer or LTURI-holder, as applicable, with the prior written
        consent of any NIMS Insurer and the Seller, which consent shall not be
        unreasonably withheld, has the option to cause the Trust Fund to adopt a
        plan of
        complete liquidation pursuant to Section 7.03(a)(i) hereof to sell all of
        its
        property (each such option, a “Call Option”); provided,
        however,
        that
        any purchase of the Trust Fund’s property on or before the Distribution Date
        that is one year after the Initial Optional Termination Date shall be made
        by
        the Bid Holder pursuant to Section 7.01(d) below. Upon exercise of such option,
        the property of the Trust Fund shall be sold to the Master Servicer 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 Collection 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 independent appraiser or appraisers mutually agreed upon
        by the
        Master Servicer, any NIMS Insurer and the Trustee (reduced, in the case of
        REO
        Property, by (1) reasonably anticipated disposition costs and (2) any amount
        by
        which the fair market value as so reduced exceeds the outstanding principal
        balance of the related Mortgage Loan plus interest accrued thereon at the
        applicable Net Mortgage Rate to the date of such purchase), (iii) any
        unreimbursed Servicing Advances and (iv) any Swap Termination Payment payable
        to
        the Swap Counterparty as a result of a termination pursuant to this Section
        7.01; provided,
        however, if
        there
        are any NIM Securities outstanding, the Master Servicer may only exercise
        its
        option after receiving the prior written consent of the holders of such NIM
        Securities and, if such consent is given, the Termination Price shall also
        include an amount equal to the sum of (1) any accrued interest on the NIM
        Securities, (2) the unpaid principal balance of any such NIM Securities and
        (3)
        any other reimbursable expenses owed by the issuer of the NIM Securities
        (the
“NIM Redemption Amount”). The Master Servicer, each Servicer, the Trustee, the
        Securities Administrator and the 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 Custodial Agreement, together with any accrued and unpaid
        compensation and any other amounts due to the Master Servicer, the Securities
        Administrator or the Trustee hereunder or the Servicers or the Custodian.
        If the
        NIMS Insurer directs the Master Servicer to exercise its right to cause the
        Trust Fund to adopt a plan of complete liquidation as described above, then
        (i)
        the Master Servicer shall cause the Trust Fund to adopt a plan of complete
        liquidation as described above, (ii) the NIMS Insurer shall remit the
        Termination Price in immediately available funds to the Master Servicer at
        least
        three Business Days prior to the applicable Distribution Date and, upon receipt
        of such funds from the NIMS Insurer, the Master Servicer shall promptly deposit
        such funds in the Collection Account and (iii) upon termination of the Trust
        Fund, the Trustee will transfer the property of the Trust Fund to the NIMS
        Insurer. The NIMS Insurer shall be obligated to reimburse the Master Servicer
        and the Trustee for its reasonable out-of-pocket expenses incurred in connection
        with its termination of the Trust Fund at the direction of the NIMS Insurer
        and
        shall indemnify and hold harmless the Master Servicer and the Trustee for
        any
        losses, liabilities or expenses resulting from any claims arising out of
        or
        relating to the Master Servicer’s termination of the Trust Fund at the direction
        of the NIMS Insurer, except to the extent such losses, liabilities or expenses
        arise out of or result from the Master Servicer’s negligence, bad faith or
        willful misconduct.

      (c) On
        any
        Distribution Date occurring on or after the Initial Optional Termination
        Date
        and provided there are no NIM Securities outstanding, the Master Servicer,
        with
        the prior written consent of the Seller, which consent shall not be unreasonably
        withheld, has the option (the “Regular Interest Purchase 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, any NIMS Insurer and the Trustee
        (reduced, in the case of REO Property, by (1) reasonably anticipated disposition
        costs and (2) any amount by which the fair market value as so reduced exceeds
        the outstanding principal balance of the related Mortgage Loan plus interest
        accrued thereon at the applicable Net Mortgage Rate to the date of such
        purchase). If the Master Servicer elects to exercise such option, each REMIC
        created pursuant to this Agreement (other than REMIC 1) 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 1) 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).

      (d) (i)
        Prior
        to exercising the Call Option pursuant to Section 7.01(b) or the Regular
        Interests Purchase Option pursuant to Section 7.01(c), the Master Servicer
        shall
        on the first Business Day of the month of the occurrence of the Initial Optional
        Termination Date, and for so long as the Master Servicer shall not have
        exercised the Call Option or the Regular Interests Purchase Option, on the
        first
        Business Day of each succeeding month (each, a “Bid Month”), the Master Servicer
        shall give written notice in the form attached hereto as Exhibit Y (the “Call
        Option Notice”) to each Call Option Holder.

       

      (ii)
         Not
        later
        than three (3) Business Days prior to the related Bid Due Date, the Master
        Servicer shall give written notice to each Call Option Holder of the Termination
        Price for the related Distribution Date. 

       

      (iii)
         Not
        later
        than the 15th day (or if such date is not a Business Day, the immediately
        succeeding Business Day) of each Bid Month (the “Bid Due Date”), if any Call
        Option Holder desires that the Master Servicer exercise the option to purchase
        the Mortgage Loans and certain other property of the Trust Fund, such Call
        Option Holder shall give written notice in the form attached hereto as Exhibit
        Z
        (the “Purchaser Call Option Notice”) to the Master Servicer, requesting that the
        Master Servicer exercise such option on behalf of such Call Option Holder.
        The
        Purchaser Call Option Notice shall include the amount to be paid by a Call
        Option Holder with respect to the proceeds or assets to be received by the
        Master Servicer for the Mortgage Loans and certain other property of the
        Trust
        Fund (the “Bid Price”); provided,
        that
        the Bid Price must be equal to or greater than the Termination
        Price.

       

      (iv)
         One
        (1)
        Business Day after the related Bid Due Date, the Master Servicer shall notify
        the Call Option Holder, if any, that has submitted the highest Bid Price
        (the
“Bid Holder”) that such Bid Holder has the right to direct the Master Servicer
        to exercise the option to purchase the Mortgage Loans and certain other property
        of the Trust Fund. The Master Servicer shall thereafter notify any Call Option
        Holder that did not submit the highest Bid Price (or did not submit a Purchaser
        Call Option Notice) of the amount of the highest Bid Price. If two or more
        Call
        Option Holder shall have bid the same Bid Price, the Bid Holder shall be
        the
        Call Option Holder with the greater Percentage Interest in the NIM Residual
        Securities or Class X Certificates, as applicable. If the Master Servicer
        does
        not receive any Purchaser Call Option Notices by such Bid Due Date, or if
        no
        Purchaser Call Option Notice specifies a Bid Price equal to or greater than
        the
        Termination Price, then the Master Servicer shall not exercise the option
        to
        purchase the Mortgage Loans and certain other property of the Trust Fund
        on such
        Distribution Date (other than in accordance with clause (vii)
        below).

       

      
        
          
          

        

        
          147

          
            

          

        

        
          
          

        

      

      (v)
         Not
        later
        than three (3) Business Days immediately preceding the Distribution Date
        in the
        related Bid Month, the Bid Holder shall remit the Bid Price as specified
        in the
        Purchaser Call Option Notice to the Master Servicer, in immediately available
        funds. Upon receipt of such funds from the Bid Holder, the Master Servicer
        shall
        promptly deposit the Termination Price in the Collection Account for subsequent
        deposit in the Certificate Account in accordance with this Agreement. Any
        amounts received by the Master Servicer from the Bid Holder in excess of
        the
        Termination Price shall be remitted to the Trustee for distribution to the
        Call
        Option Holders. In no event shall any such excess be treated as being paid
        by
        any REMIC created hereby. 

       

      (vi)
         If
        the
        Bid Holder directs the Master Servicer to exercise the option to purchase
        the
        Mortgage Loans and certain other property of the Trust Fund, then the Master
        Servicer shall (i) cause the Trust Fund to adopt a plan of complete liquidation
        pursuant to Section 7.03(a)(i) hereof to sell all of its property and (ii)
        instruct the Trustee upon termination of the Trust Fund to transfer the property
        of the Trust Fund to the Bid Holder. The Bid Holder shall be obligated to
        reimburse the Master Servicer for its reasonable out-of-pocket expenses incurred
        in connection with its exercise of the option to purchase the Mortgage Loans
        and
        certain other property of the Trust Fund and to indemnify and hold harmless
        the
        Master Servicer for any losses, liabilities or expenses resulting from any
        claims directly resulting from or relating to the Master Servicer’s exercise of
        such option, except to the extent such losses, liabilities or expenses arise
        out
        of or result from the Master Servicer’s negligence, bad faith or willful
        misconduct. The terms of such expense reimbursement and the extent of such
        indemnity may be amended accordant to an agreement between the Master Servicer
        and the Bid Holder. 

       

      (vii)
         Commencing
        on the Distribution Date of the one year anniversary of the Initial Optional
        Termination Date, and on each Distribution Date thereafter, the Master Servicer
        shall have the right to exercise the Call Option or the Regular Interests
        Purchase Option. If the Master Servicer desires to exercise the Call Option
        or
        the Regular Interests Purchase Option, the Master Servicer shall notify the
        Call
        Option Holders pursuant to a Call Option Notice that it desires to exercise
        such
        Call Option or such Regular Interest Purchase Option, as applicable, on the
        immediately succeeding Distribution Date. If one or more Call Option Holders

      (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 by the Trustee by first
        class
        mail to Certificateholders mailed promptly (and in no event later than five
        Business Days) (x) after the Trustee has received notice from the Master
        Servicer or the LTURI-holder, as applicable, of its election to cause (1)
        the
        sale of all of the property of the Trust Fund pursuant to Section 7.01(b)

        Fund Termination Event, the Trustee shall also give notice to the Master
        Servicer, the Swap Counterparty, the Cap Counterparty, the Securities
        Administrator and the Certificate Registrar at the time notice is given to
        Holders.

      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 1) will be made upon presentation and surrender of the Certificates
        (other
        than the Class LT-R 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 (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
        1) absent such purchase shall be payable to the LTURI-holder.

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

       

      (c) Any
        reasonable expenses incurred by the Trustee in connection with any Trust
        Fund
        Termination Event or any purchase of the Lower Tier REMIC 1 Uncertificated
        Regular Interests shall be reimbursed from proceeds received from such
        termination or purchase.

        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

        following additional requirements, unless the Trustee seeks (at the request
        of
        the party exercising the option to purchase all of the Mortgage Loans or

        Tier REMIC 1 Uncertificated Regular Interests pursuant to Section 7.01(b)
        or
        Section 7.01(c), respectively), and subsequently receives, an Opinion of
        Counsel
        (at the expense of such requesting party), addressed to the Trustee and any
        NIMS
        Insurer to the effect that the failure 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, the Securities Administrator, any NIMS Insurer 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 1, 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;

       

      (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 and shall pay, in the case of a Trust Fund
        Termination Event, any Net Swap Payment owed to the Swap Counterparty then
        remaining unpaid and any Swap Termination Payment owed to the Swap Counterparty
        on the related Swap Payment Date (to the extent not paid on previous Swap
        Payment Dates) in accordance with Section 5.01 and 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 agrees to
        accept the plan of complete liquidation prepared by the Depositor and adopted
        by
        the Trustee under this Section and to take such other action in connection
        therewith as may be reasonably requested by the Master Servicer or any
        Servicer.

       

      (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 the requirements
        of a
        qualified liquidation under the REMIC Provisions have been met.

      The
        NIMS
        Insurer, if any, may repurchase any Distressed Mortgage Loan for a purchase
        price equal to the outstanding principal balance of such Mortgage Loan, plus
        accrued interest thereon to the date of repurchase plus any unreimbursed
        Advances, Servicing Advances or Servicing Fees allocable to such Distressed
        Mortgage Loan. Any such repurchase shall be accomplished by the NIMS Insurer’s
        remittance of the purchase price for the Distressed Mortgage Loan to the
        Master
        Servicer for deposit into the Collection Account. The NIMS Insurer shall
        not use
        any procedure in selecting Distressed Mortgage Loans to be repurchased which
        would be materially adverse to Certificateholders.

        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

        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

        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 Percentage

        prior
        written consent of any NIMS Insurer, 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 the Trustee during such sixty-day period by such
        Certificateholders or any NIMS Insurer; it being understood and intended,
        and
        being expressly covenanted by each Certificateholder with every other
        Certificateholder, any NIMS Insurer, the Securities Administrator 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 the rights of any NIMS Insurer, or to obtain or seek to obtain
        priority over or preference to any other such Holder or any NIMS Insurer,
        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, the NIMS
        Insurer and the Trustee shall be entitled to such relief as can be given

        application states that the Applicants desire to communicate with other Holders

                  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 the Securities Administrator
        and,
        where expressly required herein, to the Master Servicer. Such instrument
        or
        instruments (as the action embodies therein and evidenced thereby) are herein
        sometimes referred to as an “act” of the Holders signing such instrument or
        instruments. Proof of execution of any such instrument or of a writing
        appointing any such agents shall be sufficient for any purpose of this Agreement
        and conclusive in favor of the Trustee, the Securities Administrator and
        the
        Master Servicer, if made in the manner provided in this Section. Each of
        the
        Trustee, the Securities Administrator 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 1 Uncertificated Regular Interests
        (whether or not such Certificates or Lower Tier REMIC 1 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, the
        Securities Administrator, the NIMS Insurer, 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 1 Uncertificated
        Regular Interest shall bind every future Holder of the same Certificate or
        Lower
        Tier REMIC 1 Uncertificated Regular Interest and the Holder of every Certificate
        or Lower Tier REMIC 1 Uncertificated Regular Interest 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 1 Uncertificated Regular
        Interest.

      The
        Certificateholders, by their purchase and acceptance of the Certificates
        or
        Lower Tier REMIC 1 Uncertificated Regular Interests, appoint Aurora Loan
        Services LLC, as Master Servicer. For and on behalf of the Depositor, the

        the
        Mortgage Loans in accordance with the provisions of this Agreement and the
        provisions of each Servicing Agreement. Notwithstanding anything in this
        Agreement, any Servicing Agreement or any Credit Risk Management Agreement
        to
        the contrary, the Master Servicer shall have no duty or obligation to enforce
        any Credit Risk Management Agreement or to supervise, monitor or oversee
        the
        activities of any Servicer under its Credit Risk Management Agreement with
        respect to any action taken or not taken by a Servicer at the direction of
        the
        Seller or pursuant to a recommendation of the Credit Risk Manager.

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

      (b) The
        Master Servicer shall promptly report to the Trustee and any NIMS Insurer
        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 and any NIMS Insurer, 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 and any NIMS Insurer 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 and any NIMS Insurer. 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 the applicable Servicer under any such bond or policy
        shall
        be remitted to the Master Servicer to the extent provided in the applicable
        Servicing Agreement.

      (a) The
        Master Servicer shall master service the Mortgage Loans and shall have full
        power and authority, subject to the REMIC Provisions and the provisions of
        Article X hereof, and each Servicer shall have full power and authority (to
        the
        extent provided in the applicable Servicing Agreement) to do any and all
        things
        that it may deem necessary or desirable in connection with the servicing
        and
        administration of the Mortgage Loans, including but not limited to the power
        and
        authority (i) to execute and deliver, on behalf of the Certificateholders
        and
        the Trustee, customary consents or waivers and other instruments and documents,
        (ii) to consent to transfers of any Mortgaged Property and assumptions of
        the
        Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds
        and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion
        of the ownership of the Mortgaged Property securing any Mortgage Loan, in
        each
        case, in accordance with the provisions of this Agreement and the applicable
        Servicing Agreement, as applicable; provided that the Master Servicer shall
        not
        take, or knowingly permit any Servicer to take, any action that is inconsistent
        with or prejudices the interests of the Trust Fund or the Certificateholders
        in
        any Mortgage Loan or the rights and interests of the Depositor, the Trustee,
        the
        Certificateholders under this Agreement. The Master Servicer shall represent
        and
        protect the interests of the Trust Fund in the same manner as it protects
        its
        own interests in mortgage loans in its own portfolio in any claim, proceeding
        or
        litigation regarding a Mortgage Loan and shall not make or knowingly permit
        any
        Servicer to make any modification, waiver or amendment of any term of any
        Mortgage Loan that would cause an Adverse REMIC Event. Without limiting the
        generality of the foregoing, the Master Servicer in its own name or in the
        name
        of a Servicer, and each Servicer, to the extent such authority is delegated
        to
        such Servicer under the applicable Servicing Agreement, is hereby authorized
        and
        empowered by the Trustee when the Master Servicer or such Servicer, as the
        case
        may be, believes it appropriate in its best judgment and in accordance with
        Accepted Servicing Practices and the applicable Servicing Agreement, to execute
        and deliver, on behalf of itself and the Certificateholders, the Trustee
        or any
        of them, any and all instruments of satisfaction or cancellation, or of partial
        or full release or discharge and all other comparable instruments, with respect
        to the Mortgage Loans and with respect to the Mortgaged Properties. The Trustee
        shall furnish to the Master Servicer, upon request, with any powers of attorney
        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 to allow each Servicer to service the Mortgage Loans,
        in each case in accordance with Accepted Servicing Practices (and the Trustee
        shall have no liability for misuse of any such powers of attorney by the
        Master
        Servicer or 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 no event shall the Master
        Servicer, without the Trustee’s written consent: (i) initiate any action, suit
        or proceeding solely under the Trustee’s name without indicating the Master
        Servicer in its applicable, representative capacity, so long as the
        jurisdictional and procedural rules will allow for this insertion to occur,
        (ii)
        initiate any action, suit or proceeding not directly relating to the servicing
        of a Mortgage Loan (including but not limited to actions, suits or proceedings
        against Certificateholders, or against the Depositor or the Transferor for
        breaches of representations and warranties) solely under the Trustee’s name,
        (iii) engage counsel to represent the Trustee in any action, suit or proceeding
        not directly relating to the servicing of a Mortgage Loan (including but
        not
        limited to actions, suits or proceedings against Certificateholders, or against
        the Depositor or the Transferor for breaches of representations and warranties),
        or (iv) prepare, execute or deliver any government filings, forms, permits,
        registrations or other documents or take any action with the intent to cause,
        and that actually causes, the Trustee to be registered to do business in
        any
        state. 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.
        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 on behalf of the Trust Fund, be
        deemed
        to be the agent of the Trustee.

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

       

      (c) As
        an
        alternative permitting a modification or effectuating a foreclosure or other
        conversion of the ownership of a Mortgaged Property, the Master Servicer
        may, at
        its option, purchase any Mortgage Loan that has become one hundred and twenty
        (120) days or more delinquent in payment (including, for the avoidance of
        doubt,
        any Mortgage Loan with respect to which the related borrower is in Bankruptcy);
        provided, however, that (i) the Master Servicer promptly notifies the related
        Servicer of its intention to purchase any such delinquent Mortgage Loan prior
        to
        its purchase and (ii) that the Master Servicer shall exercise any such option
        to
        purchase a Mortgage Loan within sixty (60) days after any such Mortgage Loan
        has
        become one hundred and twenty (120) days delinquent. The price at which the
        Master Servicer shall purchase any such delinquent Mortgage Loan shall equal
        the
        Purchase Price and such amount shall be deposited into the Collection Account
        on
        the date of purchase pursuant to Section 4.01(d)(viii). Upon receipt by the

        Servicer has exercised such option and deposited the full amount of the Purchase

        Request for Release of Documents (on the form attached hereto as Exhibit

        the
        related Mortgage File to or upon the order of the Master Servicer, and at
        the
        written requirement of the Master Servicer the Trustee shall execute and

        such instruments of transfer or assignment, in each case without recourse,

        Loan in the Master Servicer or its designee, which instruments shall be prepared
        by the Master Servicer.

                  of Servicer’s and Master Servicer’s Obligations.
                  

              

      

       

      (a) Each
        Servicing Agreement requires the applicable Servicer, respectively, to service
        the Mortgage Loans in accordance with the provisions thereof. References
        in this
        Agreement to actions taken or to be taken by the Master Servicer include
        actions
        taken or to be taken by a Servicer on behalf of the Master Servicer. Any
        fees
        and other amounts payable to a Servicer shall be deducted from amounts remitted
        to the Master Servicer by such 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 such Servicer to
        take
        such action.

       

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

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

                  of Taxes, Assessments and Similar Items.

              

      

       

      (a) To
        the
        extent provided in the applicable Servicing Agreement, the Master Servicer
        shall
        cause each Servicer to establish and maintain one or more custodial accounts
        at
        a depository institution (which may be a depository institution with which
        the
        Master Servicer or any Servicer establishes accounts in the ordinary course
        of
        its servicing activities), the accounts of which are insured to the maximum
        extent permitted by the FDIC (each, an “Escrow Account”) and to deposit therein
        any collections of amounts received with respect to amounts due for taxes,
        assessments, water rates, standard hazard insurance policy premiums, Payaheads,
        if applicable, or any comparable items for the account of the Mortgagors.
        Withdrawals from any Escrow Account may be made (to the extent amounts have
        been
        escrowed for such purpose) only in accordance with the 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 or the applicable Servicer has determined that
        the
        funds so advanced are recoverable from escrow payments, reimbursement pursuant
        to Section 4.02 or otherwise.

       

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

                  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,
        the
        Master Servicer shall provide for the servicing of the Mortgage Loans by
        a
        successor Servicer to be appointed as provided in the applicable Servicing
        Agreement.

       

      The
        parties acknowledge that notwithstanding the preceding sentence, there may
        be a
        transition period, not to exceed 90 days, in order to effect the transfer
        of
        servicing to a successor Servicer. The Master Servicer shall be entitled
        to be
        reimbursed from each Servicer (or by the Trust Fund, if the applicable 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.

       

      
        
          
          

        

        
          159

          
            

          

        

        
          
          

        

      

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

       

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

      Notwithstanding

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

        the Seller and the Master Servicer, and the Trustee, any NIMS Insurer and
        the
        Depositor shall not be deemed parties thereto and shall have no obligations,
        duties or liabilities with respect to such Servicer except as set forth in
        Section 9.10 hereof, but shall have rights thereunder as third party
        beneficiaries. It is furthermore understood and agreed by the parties hereto
        that the obligations of any Servicer are set forth in their entirety in such
        Servicer’s related Servicing Agreement and such Servicer has no obligations
        under and is not otherwise bound by the terms of this Agreement.

      (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 Securities Administrator receives
        written notice from the Trustee pursuant to Section 6.14 or Section 9.28,
        as
        applicable, the Securities Administrator shall thereupon assume all of the
        rights and obligations of such Master Servicer hereunder and under each
        Servicing Agreement entered into with respect to the Mortgage Loans. The
        Securities Administrator, its designee or any successor master servicer
        appointed by the Securities Administrator shall be deemed to have assumed
        all of
        the Master Servicer’s interest herein and therein to the same extent as if such
        Servicing Agreement had been assigned to the assuming party, except that
        the
        Master Servicer shall not thereby be relieved of any liability or obligations
        of
        the Master Servicer under such Servicing Agreement accruing prior to its
        replacement as Master Servicer, and shall be liable to the Securities
        Administrator, the Trustee and any NIMS Insurer, and hereby agrees to indemnify
        and hold harmless the Securities Administrator, the Trustee and any NIMS
        Insurer
        from and against all costs, damages, expenses and liabilities (including
        reasonable attorneys’ fees) incurred by the Securities Administrator, the
        Trustee or any NIMS Insurer as a result of such liability or obligations
        of the
        Master Servicer and in connection with the Securities Administrator’s (or other
        successor master servicer’s ) assumption (but not its performance, except to the
        extent that costs or liability of the Securities Administrator (or other
        successor master servicer’s ) 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

        Master Servicer that has been terminated shall, upon request of the Securities
        Administrator but at the expense of such Master Servicer, 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

      To
        the
        extent provided in the applicable Servicing Agreement, to the extent Mortgage
        Loans contain enforceable due-on-sale clauses, the Master Servicer shall
        cause
        the related Servicer 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

        (i)
        becoming aware of the payment in full of any Mortgage Loan or (ii) the receipt
        by the Master Servicer of a notification that payment in full has been or
        will
        be escrowed in a manner customary for such purposes, the Master Servicer
        will,
        or will cause the related Servicer to, promptly notify the Trustee (or the
        Custodian) and the Securities Administrator by a certification (which
        certification shall include a statement to the effect that all amounts received
        in connection with such payment that are required to be deposited in the
        Collection Account maintained by the Master Servicer pursuant to Section
        4.01
        have been or will be so deposited) of a Servicing Officer and shall request
        (on
        the form attached hereto as Exhibit C or on the form attached to the Custodial
        Agreement) the Trustee or the Custodian, to deliver to the applicable Servicer
        the related Mortgage File. Upon receipt of such certification and request,
        the
        Trustee or the Custodian (with the consent, and at the direction of the
        Trustee), shall promptly release the related Mortgage File to the applicable
        Servicer and the Trustee shall have no further responsibility with regard
        to
        such Mortgage File. Upon any such payment in full, the Master Servicer is
        authorized, and each Servicer, to the extent such authority is provided for
        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.

        reasonably acceptable to the Trustee) and as are necessary to the prosecution

        Servicer to return the Mortgage File to the Trustee or the Custodian, as
        applicable, when the need therefor by the Master Servicer or the applicable
        Servicer no longer exists unless the Mortgage Loan shall be liquidated, in
        which
        case, upon receipt of a certificate of a Servicing Officer similar to that
        hereinabove specified, the receipt shall be released by the Trustee or the
        Custodian, as applicable, to the Master Servicer (or the applicable
        Servicer).

        in this Agreement and to the right of each Servicer to retain its Servicing
        Fee
        and other amounts as provided in the related Servicing Agreement. The Master
        Servicer shall, and shall (to the extent provided in the applicable Servicing
        Agreement) cause each Servicer to, provide access to information and
        documentation regarding the Mortgage Loans to the Trustee, any NIMS Insurer,
        their respective agents and accountants at any time upon reasonable request
        and

        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 Liquidation Proceeds
        or Insurance Proceeds, shall be held by the Master Servicer, or by any Servicer,
        for and on behalf of the Trustee and the Certificateholders and shall be
        and
        remain the sole and exclusive property of the Trustee; provided,
        however,
        that the
        Master Servicer and each Servicer shall be entitled to setoff against, and
        deduct from, any such funds any amounts that are properly due and payable
        to the
        Master Servicer or such Servicer under this Agreement or the applicable
        Servicing Agreement and shall be authorized to remit such funds to the
        Securities Administrator in accordance with this Agreement.

       

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

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

        Servicer of its obligations under this Agreement;

         no
        litigation is pending or, to the best of the Master Servicer’s knowledge,

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

       

      (viii)
         no

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

       

      (b) It
        is

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

      Any
        cause
        of action against the Master Servicer relating to or arising out of the breach
        of any representations and warranties made in this Section shall accrue upon
        discovery of such breach by any of the Depositor, the Master Servicer, the
        Securities Administrator, the Trustee or any NIMS Insurer 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

        legal fees and related costs, judgments, and other costs and expenses resulting
        from any claim, demand, defense or assertion based on or grounded upon, or
        resulting from, a breach of the Depositor’s representations and warranties
        contained in Sections 2.03(a)(i) through (vi) hereof. It is understood and
        agreed that the enforcement of the obligation of the Depositor set forth
        in this
        Section to indemnify the Master Servicer as provided in this Section constitutes

        Depositor of the representations and warranties in Sections 2.03(a)(i) through
        (vi) hereof.

       

      (d) 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, the
        Securities Administrator, the Trustee or any NIMS Insurer or notice thereof
        by
        any one of such parties to the other parties. Notwithstanding anything in
        this
        Agreement to the contrary, the Master Servicer shall not be liable for special,
        indirect or consequential losses or damages of any kind whatsoever (including,
        but not limited to, lost profits).

        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

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

      The
        Master Servicer shall cause each Servicer (to the extent provided in the
        applicable Servicing Agreement) to, prepare and present on behalf of the
        Trustee
        and the Certificateholders all claims under the Insurance Policies with respect
        to the Mortgage Loans, and take such actions (including the negotiation,
        settlement, compromise or enforcement of the insured’s claim) as shall be
        necessary to realize recovery under such policies. Any proceeds disbursed
        to the
        Master Servicer (or disbursed to a Servicer and remitted to the Master Servicer)
        in respect of such policies or bonds shall be promptly deposited in the
        Collection Account or the Custodial Account upon receipt, except that any
        amounts realized that are to be applied to the repair or restoration of the

                  of the Primary Mortgage Insurance Policies.

              

      

       

      (a) The
        Master Servicer shall cause each Servicer to remit (with respect to any Primary
        Mortgage Insurance Policy) or shall remit on behalf of each Servicer to the
        PMI
        Insurer, the applicable PMI Insurance Premiums and provide monthly Mortgage
        Loan
        balance updates to the related PMI Insurers. The Master Servicer shall not
        take,
        or knowingly permit any Servicer (consistent with the applicable Servicing
        Agreement) to take, any action that would result in noncoverage under any
        applicable Primary Mortgage Insurance Policy of any loss which, but for the
        actions of such Master Servicer or such Servicer, would have been covered
        thereunder. The Master Servicer shall not, and shall not knowingly permit
        any
        Servicer to, cancel or refuse to renew any such Primary Mortgage Insurance
        Policy that is in effect at the date of the initial issuance of the Certificates
        and is required to be kept in force hereunder except in accordance with the
        provisions of this Agreement and the related Servicing Agreement, as applicable.
        

       

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

      The
        Master Servicer shall promptly deliver or cause each Servicer to deliver
        to the
        Custodian, upon the execution or receipt thereof the originals of the Primary
        Mortgage Insurance Policies or certificate of insurance, if applicable, and
        any

        that
        constitute portions of the Mortgage File that come into the possession of
        the
        Master Servicer or any Servicer from time to time. The Custodian, on behalf
        of
        the Trustee, shall retain possession and custody of the originals of such
        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 and delivered to the Custodian
        by the
        Master Servicer. 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 Custodian shall also retain possession
        and custody of each Mortgage File in accordance with and subject to the terms
        and conditions of this Agreement.

      The
        Master Servicer shall be entitled to withdraw from the Collection Account,
        subject to Section 5.05, the Master Servicing Fee to the extent permitted
        by

        late payment charges, as collected, if any, or otherwise (but not including
        any
        Prepayment Premium) shall be retained by the Master Servicer (or the applicable
        Servicer) and shall not be deposited in the Collection Account. If the Master
        Servicer does not retain or withdraw the Master Servicing Fee from the
        Collection Account as provided herein, the Master Servicer shall be entitled
        to
        direct the Trustee to pay the Master Servicing Fee to such Master Servicer
        by
        withdrawal from the Certificate Account to the extent that payments have
        been
        received with respect to the applicable Mortgage Loan. The Master Servicer
        shall
        be required to pay all expenses incurred by it in connection with its activities
        hereunder and shall not be entitled to reimbursement therefor except as provided
        in this Agreement. Pursuant to Sections 4.01(e) and 4.04(c), all income and
        gain
        realized from any investment of funds in the Collection Account and the
        Certificate 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.

        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.

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

        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 on the next succeeding Master Servicer Remittance

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

        upon each applicable Servicer strictly observing all requirements and deadlines
        in the performance of their duties under their related Servicing Agreements.

        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.

        nature and status thereof) and showing, for the period covered by such
        statement, the aggregate of deposits into and withdrawals from the Collection

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

        that 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.

        the Paying Agent (if other than the Trustee), the Trustee, the Securities
        Administrator or any Servicing Function Participant engaged by such parties,

        Securities Administrator 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

        shall
        not resign from the obligations and duties hereby imposed on it unless it

        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

      (a)
        Except as expressly provided herein, the Master Servicer shall not assign

        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 other Person to perform any of the duties,
        covenants or obligations to be performed by the Master Servicer hereunder;
        provided,
        however,
        that the
        Master Servicer shall have the right without the prior written consent of
        the
        Trustee, the Securities Administrator, any NIMS Insurer or the Depositor
        to
        delegate or assign to or subcontract with or authorize or appoint an Affiliate
        of the Master Servicer to perform and carry out any duties, covenants or
        obligations to be performed and carried out by the Master Servicer hereunder.
        In
        no case, however, shall any such delegation, subcontracting or assignment
        to an
        Affiliate of the Master Servicer relieve the Master Servicer of any liability
        hereunder. Notice of such permitted assignment, and the name of any such
        affiliated Subcontractor or Subservicer shall be given promptly by the Master
        Servicer to the Depositor, the Trustee, the Securities Administrator and
        any
        NIMS Insurer. If, pursuant to any provision hereof, the duties of the Master
        Servicer are transferred to a successor master servicer, the entire amount
        of
        the Master Servicing Fees and other compensation payable to the Master Servicer
        pursuant hereto, including amounts payable to or permitted to be retained
        or
        withdrawn by the Master Servicer pursuant to Section 9.21 hereof, shall
        thereafter be payable to such successor master servicer.

       

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

      (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.

        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 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 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, the
        Seller
        and the Depositor 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.

       

      The
        Master Servicer shall not be liable for any acts or omissions of any Servicer.
        In particular, the Master Servicer shall not be liable for any course of
        action
        taken by the Servicers with respect to loss mitigation of defaulted Mortgage
        Loans at the direction of the Credit Risk Manager or the Seller pursuant
        to any
        Credit Risk Management Agreement. Further, the Master Servicer shall not
        be
        liable for performance by any Servicer under any Credit Risk Management
        Agreement.

        the Depositor, the Sponsor, the Trustee, the Securities Administrator or

        information, data or materials provided by the Master Servicer, or (c) the
        negligence, bad faith or willful misconduct of the Master Servicer in connection
        with its performance hereunder. The Depositor, the Sponsor, the Trustee,
        the

        five
        calendar days of delivery to the Credit Risk Manager of such draft Form

        provided pursuant to Section 9.36 of this Agreement, neither the Credit Risk
        Manager, nor any of the directors, officers, employees or agents of the Credit
        Risk Manager, shall be under any liability to the Trustee, the Securities
        Administrator, the Certificateholders or the Depositor for any action taken
        or
        for refraining from the taking of any action in good faith pursuant to this
        Agreement, in reliance upon information provided by Servicers under the Credit
        Risk Management Agreements or for errors in judgment; provided, however,
        that
        this provision shall not protect the Credit Risk Manager or any such person
        against liability that would otherwise be imposed by reason of willful
        malfeasance, bad faith or gross negligence in its performance of its duties
        or
        by reason of reckless disregard for its obligations and duties under this
        Agreement or the Credit Risk Management Agreements. The Credit Risk Manager
        and
        any director, officer, employee or agent of the Credit Risk Manager 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, and may
        rely
        in good faith upon the accuracy of information furnished by the Servicers
        pursuant to the Credit Risk Management Agreements in the performance of its
        duties thereunder and hereunder.

      The
        Credit Risk Manager agrees to indemnify the Depositor, the Master Servicer,
        the
        Trustee and the Securities Administrator, and each of their respective
        directors, officers, employees and agents and the Trust Fund and hold each

        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 of any Subcontractor in violation of Section 9.34(e)
        or any
        failure by the Credit Risk Manager to deliver any information, report,
        certification, accountants’ letter or other material when and as required under
        this Agreement, including any report under Sections 9.25(a) or (b).

        Credit Risk Manager may be removed as Credit Risk Manager by Certificateholders
        holding not less than a 66-2/3% Voting Interests in the Trust, in the exercise
        of its or their sole discretion, at any time, without cause, upon ten (10)
        days
        prior written notice. The Certificateholders shall provide such written notice
        to the Trustee and upon receipt of such notice, the Trustee shall provide

                Section
                  10.01

              	
                REMIC
                  Administration.

              

      

       

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

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

       

      (c) The
        Securities Administrator shall represent the Trust Fund in any administrative
        or
        judicial proceeding relating to an examination or audit by any governmental
        taxing authority with respect thereto. The Securities Administrator 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 Securities
        Administrator in fulfilling its duties hereunder (including its duties as
        tax
        return preparer). The Securities Administrator shall be entitled to
        reimbursement of expenses to the extent provided in clause (i) above from
        the
        Securities Administration Account, provided,
        however,
        the
        Securities Administrator shall not be entitled to reimbursement for expenses
        incurred in connection with the preparation of tax returns and other reports
        as
        required by Section 6.20 and this Section.

       

      (d) The
        Securities Administrator shall prepare, the Trustee shall sign and the
        Securities Administrator shall file, all of each REMIC’s federal and appropriate
        state tax and information returns as such REMIC’s direct representative. The
        expenses of preparing and filing such returns shall be borne by the Securities
        Administrator.

       

      (e) The
        Securities Administrator or its designee 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 Securities Administrator shall provide (i) to the Treasury
        or
        other governmental authority such information as is necessary for the
        application of any tax relating to the transfer of a Residual Certificate
        to any
        disqualified person or organization pursuant to Treasury Regulation
        1.860E-2(a)(5) and any person designated in Section 860E(e)(3) of the Code
        and
        (ii) to the Trustee such information as is necessary for the Trustee to provide
        to the Certificateholders such information or reports as are required by
        the
        Code or REMIC Provisions.

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

       

      (g) Each
        Holder of a Residual Certificate shall pay when due any and all taxes imposed
        on
        the related REMIC by federal or state governmental authorities. To the extent
        that such taxes are not paid by a Residual Certificateholder, the Trustee,
        at
        the direction of the Securities Administrator, shall pay any remaining REMIC
        taxes out of current or future amounts otherwise distributable to the Holder
        of
        the Residual Certificate in any 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 any such REMIC, as the
        case
        may be.

       

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

       

      (i) No
        additional contributions of assets shall be made to any REMIC, except as
        expressly provided in this Agreement.

       

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

       

      (k) On
        or
        before October 15 of each calendar year beginning in 2007, the Securities
        Administrator shall deliver to the Trustee and any NIMS Insurer an Officer’s
        Certificate stating, without regard to any actions taken by any party other
        than
        the Securities Administrator, the Securities Administrator’s compliance with
        provisions of this Section 10.01.

      (l) The
        Securities Administrator shall treat each of the Basis Risk Reserve Fund
        and the
        Supplemental Interest Trust (exclusive of the Collateral Account) as an outside
        reserve fund within the meaning of Treasury Regulation Section 1.860G-2(h)
        that
        is owned by the Holders of the Class X Certificates and that is not an asset
        of
        any REMIC and all amounts deposited into the Basis Risk Reserve Fund or the
        Supplemental Interest Trust shall be treated as amounts distributed to the
        Class
        X Certificateholders. The Securities Administrator shall treat the Collateral
        Account as an outside reserve fund that is owned by the Swap Counterparty
        and
        the Cap Counterparty.

       

      (m) For
        federal income tax purposes, upon any sale of the property held by the Trust
        Fund pursuant to Section 7.01(b), any NIM Redemption Amount paid by the Master
        Servicer shall not be treated as a portion of the purchase price paid for
        such
        property but shall instead be treated as an amount paid by the Master Servicer
        to the Holder of the Class X Certificates in exchange for an interest in
        the
        Class X Certificates immediately before the purchase of the property held
        by the
        Trust Fund.

       

      (n) The
        Securities Administrator shall treat the beneficial owners of Certificates
        (other than the Class P, Class X, Class LT-R and Class R Certificates) as
        having
        entered into a notional principal contract with the beneficial owners of
        the
        Class X Certificates. Pursuant to each such notional principal contract,
        all
        beneficial owners of LIBOR Certificates shall be treated as having agreed
        to
        pay, on each Distribution Date, to the beneficial owners of the Class X
        Certificates an aggregate amount equal to the excess, if any, of (i) the
        amount
        payable on such Distribution Date on the interest in the Upper Tier REMIC
        corresponding to such Class of Certificates over
        (ii)
        the
        amount payable on such Class of Certificates on such Distribution Date (such
        excess, a “Class I Shortfall”). A Class I Shortfall payable from interest
        collections shall be allocated to each Class of Certificates to the extent
        that
        interest accrued on such Class for the related Accrual Period at the Certificate
        Interest Rate for a Class, computed by substituting “REMIC 3 Net Funds Cap” for
        the applicable “Net Funds Cap” in the definition thereof, exceeds the amount of
        interest accrued for the related Accrual Period based on the applicable Net
        Funds Cap, and a Class I Shortfall payable from principal collections shall
        be
        allocated to the most subordinate Class of Certificates with an outstanding
        principal balance to the extent of such balance. In addition, pursuant to
        such
        notional principal contract, the beneficial owner of the Class X Certificates
        shall be treated as having agreed to pay Basis Risk Shortfalls and Unpaid
        Basis
        Risk Shortfalls to the Owners of the LIBOR Certificates in accordance with
        the
        terms of this Agreement. Any payments to the Certificates in light of the
        foregoing shall not be payments with respect to a “regular interest” in a REMIC
        within the meaning of Code Section 860G(a)(1). However, any payment from
        the
        Certificates of a Class I Shortfall shall be treated for tax purposes as
        having
        been received by the beneficial owners of such Certificates in respect of
        their
        Interests in the Upper Tier REMIC and as having been paid by such beneficial
        owners to the Supplemental Interest Trust pursuant to the notional principal
        contract. Thus,
        each Certificate (other than a Class P, Class R and Class LT-R Certificates)
        shall be treated as representing not only ownership of regular interests
        in the
        Upper Tier REMIC, but also ownership of an interest in (and obligations with
        respect to) a notional principal contract. For tax purposes, the notional
        principal contract shall be deemed to have a value in favor of the Certificates
        entitled to receive Basis Risk Shortfalls and Unpaid Basis Risk Shortfalls
        of
        $48,853.75 as of the Closing Date.

      (o) Notwithstanding
        the priority and sources of payments set forth in Article V hereof or otherwise,
        the Securities Administrator shall account for all distributions on the
        Certificates as set forth in this Section 10.01. In no event shall any payments
        of Basis Risk Shortfalls or Unpaid Basis Risk Shortfalls provided for in
        this
        Section 10.01 be treated as payments with respect to a “regular interest” in a
        REMIC within the meaning of Code Section 860G(a)(1).

      Neither
        the Depositor, the Master Servicer nor the Trustee shall sell, dispose of,

        (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,

        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 the Trustee and any NIMS Insurer has received an Opinion of
        Counsel
        addressed to the Trustee (at the expense of the party causing such sale,
        disposition, or substitution) that such disposition, acquisition, substitution,
        or acceptance will not (a) result in an Adverse REMIC Event, (b) affect the
        distribution of interest or principal on the Certificates or (c) result in
        the
        encumbrance of the assets transferred or assigned to the Trust Fund (except
        pursuant to the provisions of this Agreement).

      Upon
        the
        occurrence of an Adverse REMIC Event due to the negligent performance by
        the
        Trustee or the Securities Administrator, as applicable, of its duties and
        obligations set forth herein, the Trustee or the Securities Administrator,
        as
        applicable, shall indemnify any NIMS Insurer, the Holder of the related Residual
        Certificate or the Trust Fund, as applicable, against any and all losses,
        claims, damages, liabilities or expenses (“Losses”) resulting from such
        negligence; provided,
        however,
        that
        neither the Trustee nor the Securities Administrator shall be liable for
        any
        such Losses attributable to the action or inaction of the Master Servicer,
        the
        Depositor, the Class X Certificateholders, the Holder of such Residual
        Certificate or the Securities Administrator (with regard to the Trustee),
        as
        applicable, nor for any such Losses resulting from misinformation provided
        by
        the Holder of such Residual Certificate on which the Securities Administrator
        has relied. The foregoing shall not be deemed to limit or restrict the rights
        and remedies of the Holder of such Residual Certificate now or hereafter
        existing at law or in equity. Notwithstanding the foregoing, however, in
        no
        event shall the Trustee or the Securities Administrator, as applicable, have
        any
        liability (1) for any action or omission that is taken in accordance with
        and in
        compliance with the express terms of, or which is expressly permitted by
        the
        terms of, this Agreement or any Servicing Agreement, (2) for any Losses other
        than arising out of a negligent performance by the Trustee or the Securities
        Administrator, as applicable, of its duties and obligations set forth herein,
        and (3) for any special or consequential damages to Certificateholders (in
        addition to payment of principal and interest on the Certificates); provided,
        however,
        that
        this sentence shall not apply in connection with any failure by the Securities
        Administrator to comply with the provisions of Subsections 6.01(l) hereof
        and
        Subsections 9.25(a) or (b) hereof. In addition, neither the Trustee nor the

        act of any other party hereto.

                REO
                  Property. 

              

      

       

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

       

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

        contemporaneous agreements, understandings, inducements and conditions, express

      (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, the Securities Administrator
        and the Trustee, with the consent of any NIMS Insurer, but without the consent
        of the Credit Risk Manager or the Swap Counterparty (except to the extent
        that
        the rights or obligations of (1) the Credit Risk Manager or the Swap
        Counterparty hereunder or (2) the Swap Counterparty under the Swap Agreement
        are
        affected thereby, and except to the extent the ability of the Trustee on
        behalf
        of the Supplemental Interest Trust and the Trust Fund to perform fully and
        timely its obligations under the Swap Agreement is adversely affected, in
        which
        case prior written consent of the Swap Counterparty is required) and without
        notice to or the consent of any of the Holders, (i) to cure any ambiguity,
        (ii)
        to cause the provisions herein to conform to or be consistent with or in
        furtherance of the statements made with respect to the Certificates, the
        Trust
        Fund or this Agreement in any Offering Document, or to correct or supplement
        any
        provision herein which may be inconsistent with any other provisions herein
        or
        with the provisions of any Servicing Agreement, (iii) to make any other
        provisions with respect to matters or questions arising under this Agreement
        or
        (iv) to add, delete, or amend any provisions to the extent necessary or
        desirable to comply with any requirements imposed by the Code and the REMIC
        Provisions as evidenced by an Opinion of Counsel. No such amendment effected
        pursuant to the preceding sentence shall, as evidenced by an Opinion of Counsel,
        result in an Adverse REMIC Event, nor shall such amendment effected pursuant
        to
        clause (iii) of such sentence adversely affect in any material respect the
        interests of any Holder. Prior to entering into any amendment without the
        consent of Holders pursuant to this paragraph, the Trustee, any NIMS Insurer
        and
        the Swap Counterparty shall be provided with an Opinion of Counsel addressed
        to
        the Trustee, any NIMS Insurer and the Swap Counterparty (at the expense of
        the
        party requesting such amendment) to the effect that such amendment is permitted
        under this Section. Any such amendment shall be deemed not to adversely affect
        in any material respect any Holder, if the Trustee receives written confirmation
        from each Rating Agency that such amendment will not cause such Rating Agency
        to
        reduce then current rating assigned to the Certificates.

       

      (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, the Securities
        Administrator and the Trustee, with the consent of any NIMS Insurer, but
        without
        the consent of the Credit Risk Manager or the Swap Counterparty (except to
        the
        extent that the rights or obligations of (1) the Credit Risk Manager or the
        Swap
        Counterparty hereunder or (2) the Swap Counterparty under the Swap Agreement
        are
        affected thereby, or the ability of the Trustee on behalf of the Supplemental
        Interest Trust and the Trust Fund to perform fully and timely its obligations
        under the Swap Agreement is adversely affected, in which case prior written
        consent of the Swap Counterparty is required) and with the consent of the
        Holders of not less than 66-2/3% of the Class Principal Amount (or Percentage
        Interest) of each Class of Certificates affected thereby for the purpose
        of
        adding any provisions to or changing in any manner or eliminating any of
        the
        provisions of this Agreement or of modifying in any manner the rights of
        the
        Holders; provided,
        however,
        that no
        such amendment shall be made unless the Trustee and any NIMS Insurer receives
        an
        Opinion of Counsel addressed to the Trustee and the NIMS Insurer, at the
        expense
        of the party requesting the change, that such change will not cause an Adverse
        REMIC Event and is permitted hereunder; and provided further, that no such
        amendment may (i) reduce in any manner the amount of, or delay the timing
        of,
        payments received on Mortgage Loans which are required to be distributed
        on any
        Certificate, without the consent of the Holder of such Certificate or (ii)
        reduce the aforesaid percentages of Class Principal Amount (or Percentage
        Interest) of Certificates of each Class, the Holders of which are required
        to
        consent to any such amendment without the consent of the Holders of 100%
        of the
        Class Principal Amount (or Percentage Interest) of each Class of Certificates
        affected thereby. For purposes of this paragraph, references to “Holder” or
“Holders” shall be deemed to include, in the case of any Class of Book-Entry
        Certificates, the related Certificate Owners.

      (c) 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 Securities Administrator, the LTURI-holder and the Trustee,
        but without the consent of the Credit Risk Manager, the Cap Counterparty,
        or the
        Swap Counterparty (except to the extent that the rights or obligations of
        (1)
        the Credit Risk Manager, the Cap Counterparty or the Swap Counterparty hereunder
        or (2) the Cap Counterparty or the Swap Counterparty under the Interest Rate
        Cap
        Agreement or the Swap Agreement, respectively, or the ability of the Trustee
        on
        behalf of the Supplemental Interest Trust and the Trust Fund to perform fully
        and timely its obligations under the Interest Rate Cap Agreement or Swap
        Agreement, as applicable, is adversely affected, in which case prior written
        consent of the Credit Risk Manager, the Cap Counterparty or the Swap
        Counterparty, as applicable, is required). Prior to entering into any amendment
        pursuant to this paragraph, the Trustee and the Swap Counterparty shall be
        provided with an Opinion of Counsel addressed to the Trustee, any NIMS Insurer
        and the Swap Counterparty (at the expense of the party requesting such
        amendment) to the effect that such amendment is permitted under this Section
        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,
        the Swap Counterparty, any NIMS Insurer 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.

       

      (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 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.
        

       

      (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, the Securities
        Administrator and the Trustee to the extent necessary, in the judgment of
        the
        Depositor and its counsel, to comply with the Rules.

      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 Percentage Interest),
        Certificates owned by the Depositor, the Master Servicer, the Trustee, the

      The
        Seller agrees that it shall provide written notice to the Master Servicer,
        the
        Securities Administrator, the Swap Counterparty, any NIMS Insurer and the
        Trustee thirty days prior to any proposed transfer or assignment by such
        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
        other Person other than the initial Servicer under such Servicing Agreement;
        provided that the Seller shall not be required to provide prior notice of
        (i) any transfer of servicing by Option One to Wells Fargo that occurs
        within three months of the Closing Date or to an entity that is a Servicer
        on
        the Closing Date or (ii) any assignment of any Servicing rights from one
        Seller to the other Seller. In addition, the ability of the Seller to transfer
        or assign its rights and delegate its duties under a Servicing Agreement
        or to
        transfer the servicing thereunder to a successor servicer shall be subject
        to
        the following conditions:

       

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

       

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

       

      (iii)
         Such
        successor servicer must satisfy the seller/servicer eligibility standards
        in the
        applicable Servicing Agreement, exclusive of any experience in mortgage loan
        origination;

       

      (iv)
         Such
        successor servicer must execute and deliver to the Trustee and the Master
        Servicer an agreement, in form and substance reasonably satisfactory to the
        Trustee and the Master Servicer, that contains an assumption by such successor
        servicer of the due and punctual performance and observance of each covenant
        and
        condition to be performed and observed by the applicable Servicer under the
        applicable Servicing Agreement or, in the case of a transfer of servicing
        to a
        party that is already a Servicer pursuant to this Agreement, an agreement
        to add
        the related Mortgage Loans to the Servicing Agreement already in effect with
        such Servicer;

       

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

      (vi)
         The
        Seller shall, at its cost and expense, take such steps, or cause the terminated
        Servicer to take such steps, as may be necessary or appropriate to effectuate
        and evidence the transfer of the servicing of the Mortgage Loans to such
        successor servicer, including, but not limited to, the following: (A) to
        the
        extent required by the terms of the Mortgage Loans and by applicable federal
        and
        state laws and regulations, the Seller shall cause the prior Servicer to
        timely
        mail to each obligor under a Mortgage Loan any required notices or disclosures
        describing the transfer of servicing of the Mortgage Loans to the successor
        servicer; (B) prior to the effective date of such transfer of servicing,
        the

        collection of any federal, state or local taxes legally required to be paid
        with
        respect to a Residual Certificate. In addition, the Transferor has conducted
        a
        reasonable investigation at the time of the transfer and found that the
        Transferee had historically paid its debts as they came due and found no
        significant evidence to indicate that the Transferee will not continue to
        pay
        its debts as they become due.

    (1) The
      interest rate with respect to any Distribution Date (and the related Accrual
      Period) for each of these REMIC I-1 Interests is a per annum rate equal to
      the
      weighted average of the interest rates on the SWAP REMIC Regular Interests
      for
      such Distribution Date, provided however, that for any Distribution Date on
      which the Class LTI1-IO Interest is entitled to a portion of interest accruals
      on a SWAP REMIC Regular Interest ending with a designation “A” as described in
      footnote 4 below, such weighted average shall be computed by first subjecting
      the rate on such SWAP REMIC Regular Interest to a cap equal to Swap LIBOR for
      such Distribution Date.

    (2) The
      initial principal amount for each of these REMIC I-1 Interests equals 50% of
      the
      initial principal amount of the Corresponding Class of
      Certificates.

     

    (3) This
      interest shall have an initial principal balance equal to the excess of (i)
      the
      Aggregate Loan Balance for Pool 1 as of the Cut-off Date over (ii) the aggregate
      initial principal balance of the REMIC I-1 Marker Classes.

     

    (4) The
      Class
      LTI1-IO Interest is an interest-only class that does not have a principal
      balance. For only those Distribution Dates listed in the first column of the
      table below, the Class LTI1-IO shall be entitled to interest accrued on the
      SWAP
      REMIC Regular Interest listed in the second column below at a per annum rate
      equal to the excess, if any, of (i) the interest rate for such SWAP REMIC
      Regular Interest for such Distribution Date over (ii) Swap LIBOR for such
      Distribution Date.

              The
                Class LTI1-R Interest is the sole Class of residual interest in REMIC
                I-1.
                It does not have an interest rate or a principal balance. It shall
                be
                represented by the Class R-I
                Certificate.

    (1) The
      interest rate with respect to any Distribution Date (and the related Accrual
      Period) for each of these REMIC I-2 Interests is a per annum rate equal to
      the
      Certificate Interest Rate for the Related Certificates, provided that in lieu
      of
      the Pool 1 Net Funds Cap set forth in the applicable Certificate Interest Rate,
      the Pool 1 Net Rate (as adjusted, in the case of any such REMIC I-2 Interest
      the
      Class of Related Certificates of which accrues interest on the basis of a
      360-day year consisting of twelve 30-day months, to reflect accruals on the
      basis of a 360-day year consisting of twelve 30-day months) shall be
      used.

     

    (2) The
      Uncertificated Class 1-X Interest shall have an initial principal balance equal
      to $1,028,910.61. The Uncertificated Class 1-X Interest shall accrue interest
      on
      a notional balance equal to the 1-X Component Notional Balance at a rate equal
      to the 1-X Component Interest Rate. The Uncertificated Class 1-X Interest shall
      be represented by the Class X Certificates.

     

    (3) The
      Class
      LTI2-IO Interest shall have no principal amount and will not have an interest
      rate, but will be entitled to 100% of the interest accrued with respect to
      the
      Class LTI1-IO Interest. The Class LTI2-IO Interest shall be represented by
      the
      Class X Certificates.

     

    (4) The
      Residual I Interest is the sole Class of residual interest in REMIC I-2. It
      does
      not have an interest rate or a principal balance.

     

    Pool
      2 REMICs

     

     

    REMIC
      II-1

     

    REMIC
      II-1 shall hold as its assets all rights related to Pool 2 (other than the
      Funding Account, rights to Prepayment Penalty Amounts and the right to receive
      FPD Premiums). 

     

    Solely
      for purposes of the REMIC Provisions, the Class 2-AX Certificates shall
      represent a “specified portion” of the interest on the Pool 2 Mortgage Loans
      disregarding the portion of the Funding Amount that is otherwise treated as
      a
      Pool 2 Mortgage Loan. Such “specified portion” shall accrue at a per annum rate
      equal to (A) for the first Distribution Date, the product of (I) 0.2777552869%
      and (y) a fraction the numerator of which is the aggregate Scheduled Principal
      Balance of the Pool 2 Mortgage Loans as of the Cut-off Date (including the
      portion of the Funding Amount that is treated as a Pool 2 Mortgage Loan) and
      the
      denominator of which is the aggregate Scheduled Principal Balance of the Pool
      2
      Mortgage Loans as of the Cut-off Date (disregarding the portion of the Funding
      Amount that is otherwise treated as a Pool 2 Mortgage Loan) and (B) for all
      other Distribution Dates on which the Class 2-AX Certificates are entitled
      to
      interest payments, 0.2777552869%.

     

    Each
      of
      the Pool 2 Certificates (other than the Class R-II Certificates and exclusive
      of
      the right of the Class 2-AX Certificates to receive FPD Premiums) is referred
      to
      herein as a REMIC II-1 Regular Interest and is hereby designated as a regular
      interest in REMIC II-1. The Class LTII1-R Interest is hereby designated as
      the
      sole class of residual interest in REMIC II-1. The Class LTII1-R Interest shall
      be represented by the Class R-II Certificate. The entitlement of the Class
      R-II
      Certificate to payments of principal and interest shall be attributable to
      its
      representation of the Class LTII1-R Interest.

    The
      REMIC
      II-1 Regular Interests and the Class LTII1-R Interest are referred to herein
      as
      the REMIC II-1 Interests.

     

    All
      calculations of interest on each regular interest in the SWAP REMIC, REMIC
      I-1
      and REMIC I-2 (other than the REMIC regular interest represented by the Class
      1-A2 Certificates) will be made on an “actual/360” basis. All calculations of
      interest on each regular interest in REMIC II-1 and the REMIC regular interest
      represented by the Class 1-A2 Certificates will be made on a “30/360”
basis.

        dollar amount of principal to which the Holder thereof is then entitled
        hereunder, such amount being equal to the initial principal amount set forth
        on
        the face of such Certificate (plus, in the case of any Negative Amortization
        Certificate, any Deferred Interest allocated thereto on previous Distribution
        Dates, and plus, in the case of any Accrual Certificate, its Percentage Interest
        of any related Accrual Amount for each previous Distribution Date), as reduced

        in

        Amount allocated to such Certificates; provided, however, that on any
        Distribution Date on which a Subsequent Recovery for a Mortgage Pool in Pool
        2
        is distributed, the Certificate Principal Amount of any Class of related
        Certificates then outstanding for which any Realized Loss or any Subordinate
        Certificate Writedown Amount has been applied will be increased, in order
        of
        seniority, by an amount equal to the lesser of (i) the amount the Class of
        Certificates has been reduced by any Realized Losses or any Subordinate
        Certificate Writedown Amount which have not been previously offset by any
        Subsequent Recovery pursuant to this proviso and (ii) the total amount of
        any
        Subsequent Recovery for such Mortgage Pool distributed on such date to
        Certificateholders (as reduced (x) by increases in the Certificate Principal
        Amount of more senior Classes of Certificates related to such Mortgage Pool
        on
        such Distribution Date and (y) to reflect a proportionate amount of what
        would
        (but for this clause (y) have been the increases in the Certificate Principal
        Amount of Classes of Certificates related to such Mortgage Pool of equal
        seniority on such Distribution Date). For purposes of Article V hereof, unless
        specifically provided to the contrary, Certificate Principal Amounts shall
        be
        determined as of the close of business of the immediately preceding Distribution
        Date, after giving effect to all distributions made on such date. Notional
        Certificates are issued without Certificate Principal Amounts.

        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.

      

      
        
          
            
            

          

          
            32

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

        an
        obligation of an insurance company or other corporation whose long-term debt
        is

        Substitute Mortgage Loan:
        In the

        Loan
        that, on the date of substitution, (i) has a Scheduled Principal Balance
        (together with that of any other mortgage loan substituted for the same Deleted
        Mortgage Loan) as of the Due Date in the month in which such substitution
        occurs
        not in excess of the Scheduled Principal Balance of the related Deleted Mortgage
        Loan, provided, however, that, to the extent that the Scheduled Principal
        Balance of such Mortgage Loan is less than the Scheduled Principal Balance
        of
        the related Deleted Mortgage Loan, then such differential in principal amount,
        together with interest thereon at the applicable Mortgage Rate net of the
        applicable Master Servicing Fee and the applicable Servicing Fee from the
        date
        as to which interest was last paid through the end of the Due Period in which
        such substitution occurs, shall be paid by the party effecting such substitution
        to the Master Servicer for deposit into the Collection Account, and shall
        be
        treated as a Principal Prepayment hereunder; (ii) has a Net Mortgage Rate
        not
        lower than the Net Mortgage Rate of the related Deleted Mortgage Loan and
        will
        be a Discount Mortgage Loan if the Deleted Mortgage Loan was a Discount Mortgage
        Loan or a Non-Discount Mortgage Loan if the Deleted Mortgage Loan was a
        Non-Discount Mortgage Loan; (iii) has a remaining stated term to maturity
        not
        more than eighteen months longer than, and not more than eighteen months

        Loan; (iv) (A) has a Loan-to-Value Ratio as of the date of such substitution
        of
        not greater than 80%, provided, however, that if the related Deleted Mortgage
        Loan has a Loan-to-Value Ratio of greater than 80%, then the Loan-to-Value
        Ratio
        of such substitute Mortgage Loan may be greater than 80% but shall not be
        greater than the Loan-to-Value Ratio of the related Deleted Mortgage Loan
        and
        (B) the addition of such substitute Mortgage Loan does not increase the weighted
        average Loan-to-Value Ratio of the related Mortgage Pool by more than 5%;

        Loans set forth herein, as of the date as of which such substitution occurs;

        months
        immediately preceding such date of substitution; (ix) is covered by a Primary
        Mortgage Insurance Policy if the related Deleted Mortgage Loan is so covered,
        and the Loan-to-Value Ratio of such Mortgage Loan is greater than 80%; (x)
        has a
        Credit Score not greater than 20 points lower than the Credit Score of the
        related Deleted Mortgage Loan, provided, however, that if the Deleted Mortgage
        Loan does not have a Credit Score, then such substitute Mortgage Loan shall
        have
        a Credit Score equal to or greater than 700; (xi) has its initial adjustment
        date after the related Reset Date; and (xii) has a gross margin no less than
        the
        related Deleted Mortgage Loan. In the event that either one mortgage loan
        is
        substituted for more than one Deleted Mortgage Loan or more than one mortgage
        loan is substituted for one or more Deleted Mortgage Loans, then (a) the
        Scheduled Principal Balance referred to in clause (i) above shall be determined
        such that the aggregate Scheduled Principal Balance of all such substitute
        Mortgage Loans shall not exceed the aggregate Scheduled Principal Balance

        Substitute Mortgage Loan shall not exceed the Final Scheduled Distribution
        Date
        of any Class of Certificates. Whenever a Qualifying Substitute Mortgage Loan
        is
        substituted for a Deleted Mortgage Loan pursuant to this Agreement, the party
        effecting such substitution shall certify such qualification in writing to
        the
        Trustee and the Master Servicer.

        balance of such Mortgage Loan immediately prior to such Deficient Valuation

        Valuation. In determining whether a Realized Loss on a Liquidated Mortgage
        Loan
        is a Realized Loss of interest or principal, Liquidation Proceeds shall be
        allocated, first, to payment of expenses related to such Liquidated Mortgage
        Loan, then to accrued unpaid interest and finally to reduce the principal
        balance of the Mortgage Loan.

        before the Distribution Date in February 2010, prior to giving effect to
        any
        distributions on such Distribution Date, the Senior Enhancement Percentage
        for
        Pool 2 for such Distribution Date is greater than or equal to twice the related
        Initial Senior Enhancement Percentage, then the Senior Prepayment Percentage
        for
        Pool 2 for such Distribution Date will equal the related Senior Percentage
        plus
        50% of the related Subordinate Percentage for such Pool 2 and (iii) unless

        in
        the paragraph above (calculated without regard to clause (ii) or clause (iii)
        of
        the paragraph above) shall be effective on any Distribution Date if, as of
        the
        first Distribution Date as to which any such decrease applies, (i) the average
        outstanding principal balance on such Distribution Date and for the preceding
        five Distribution Dates of all Mortgage Loans in Pool 2 that were delinquent
        60
        days or more (including for this purpose any Mortgage Loans in foreclosure
        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) is greater than or equal
        to

        with respect to each Distribution Date on or after the eighth anniversary
        and
        prior to the ninth anniversary of the first Distribution Date, 35% of the
        related Original Group Subordinate Amount, (d) with respect to each Distribution
        Date on or after the ninth anniversary and prior to the tenth anniversary
        of the
        first Distribution Date, 40% of the related Original Group Subordinate Amount,
        (e) with respect to each Distribution Date on or after the tenth anniversary

        assign to the Trustee all of its rights and interest under the Mortgage Loan
        Sale Agreement; including all rights of the Seller under the applicable
        Servicing Agreement and any related Transfer Agreement (including the right

        assignment, and shall be entitled to exercise all rights of the Depositor
        under
        the Mortgage Loan Sale Agreement as if, for such purpose, it were the Depositor.
        The Trustee is hereby directed to execute and deliver the Servicing Agreement
        (to the extent it is a party thereto) and perform in accordance therewith.

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

       

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

       

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

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

        case,
        with all necessary intervening endorsements as applicable);

       

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

      (iii) with
        respect to each Mortgage Loan other than a Cooperative Loan, the original
        recorded Mortgage with evidence of recording indicated thereon and the original
        recorded power of attorney, if the Mortgage was executed pursuant to a power
        of
        attorney, with evidence of recording thereon or, if such Mortgage or power
        of
        attorney has been submitted for recording but has not been returned from
        the
        applicable public recording office, has been lost or is not otherwise available,
        a copy of such Mortgage or power of attorney, as the case may be, certified
        to
        be a true and complete copy of the original submitted for recording. If,
        in
        connection with any Mortgage Loan, the Depositor cannot deliver the Mortgage
        with evidence of recording thereon on or prior to the Closing Date because
        of a
        delay caused by the public recording office where such Mortgage has been
        delivered for recordation or because such Mortgage has been lost, the Depositor
        shall deliver or cause to be delivered to the Trustee (or the applicable

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

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

       

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

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

       

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

        Loan Trust Mortgage Pass Through Certificates, Series 2007-2,” without recourse
        for each Mortgage Loan;

       

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

      

      
        
          
            
            

          

          
            65

            
              

            

          

          
            
            

          

        

      

      

       

      (vii) the
        original Primary Mortgage Insurance Policy or certificate, if private mortgage
        guaranty insurance is required;

       

      (viii) with

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

       

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

       

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

       

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

       

      (c) (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 need not
        be
        recorded if, in the Opinion of Counsel (which must be from Independent counsel)
        acceptable to the Trustee, the Rating Agencies and any NIMS Insurer, recording
        in such states is not required to protect the Trustee’s interest in the related
        Non-MERS Mortgage Loans. Subject to the preceding sentence, as soon as
        practicable after the Closing Date (but in no event more than 3 months
        thereafter except to the extent delays are caused by the applicable recording
        office), the Master Servicer (or the applicable Custodian), at the expense
        of
        the Depositor and with the cooperation of the applicable Servicer, shall

        the related Mortgages are recorded each Assignment of Mortgage referred to
        in
        subsection (b)(v) above with respect to a Non-MERS Mortgage Loan. With respect
        to each Cooperative Loan, the Master Servicer (or the applicable Custodian),
        at
        the expense of the Depositor and with the cooperation of the applicable
        Servicer, shall cause such Servicer to take such actions as are necessary
        under
        applicable law in order to perfect the interest of the Trustee in the related
        Mortgaged Property.

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

       

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

       

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

       

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

       

      (g) The
        issuing entity is hereby named Structured Adjustable Rate Mortgage Loan Trust,
        Series 2007-2.

       

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

       

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

       

      (b) Within
        45
        days after the Closing Date, the Trustee, or the applicable Custodian, on
        behalf
        of the Trustee, will, for the benefit of Holders of the Certificates and
        any
        NIMS Insurer, review each Mortgage File to ascertain that all required documents
        set forth in Section 2.01 have been received and appear on their face to
        contain
        the requisite signatures by or on behalf of the respective parties thereto,
        and
        shall deliver to the Trustee, the Depositor, the Master Servicer and any
        NIMS
        Insurer an Interim Certification in the form annexed hereto as Exhibit B-2
        (or
        in the form annexed to the applicable Custodial Agreement as Exhibit B-2,
        as
        applicable) to the effect that, as to each Mortgage Loan listed in the Mortgage
        Loan Schedule (other than any Mortgage Loan prepaid in full or any 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.

      

      
        
          
            
            

          

          
            67

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

      

      
        
          
            
            

          

          
            68

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

      Section
        2.03. Representations
        and Warranties of the Depositor.

       

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

       

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

       

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

       

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

       

      (iv) this
        Agreement has been duly executed and delivered by the Depositor and, assuming
        due authorization, execution and delivery by the Trustee and the Master
        Servicer, constitutes a valid and binding obligation of the Depositor
        enforceable against it in accordance with its terms except as such
        enforceability may be subject to (A) applicable bankruptcy and insolvency
        laws
        and other similar laws affecting the enforcement of the rights of creditors
        generally and (B) general principles of equity regardless of whether such
        enforcement is considered in a proceeding in equity or at law;

       

      (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

      

      
        
          
            
            

          

          
            69

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      (b) The
        representations and warranties of each Transferor with respect to the related
        Mortgage Loans in the applicable Transfer Agreement, which have been assigned
        to
        the Trustee hereunder, were made as of the date specified in the applicable
        Transfer Agreement (or underlying agreement, if such Transfer Agreement is
        in
        the form of an assignment of a prior agreement). To the extent that any fact,
        condition or event with respect to a Mortgage Loan constitutes a breach of
        both
        (i) a representation or warranty of the applicable Transferor under the
        applicable Transfer Agreement and (ii) a representation or warranty of Lehman
        Brothers Holdings under the Mortgage Loan Sale Agreement, the only right
        or
        remedy of the Trustee or of any Certificateholder shall be the Trustee’s right
        to enforce the obligations of the applicable Transferor under any applicable
        representation or warranty made by it. Lehman Brothers Holdings shall have
        no
        obligation or liability with respect to any breach of a representation or
        warranty made by it with respect to the Mortgage Loans if the fact, condition
        or
        event constituting such breach also constitutes a breach of a representation
        or
        warranty made by the applicable Transferor in the applicable Transfer Agreement,
        without regard to whether such Transferor fulfills its contractual obligations
        in respect of such representation or warranty. The Depositor shall have no
        obligation or liability with respect to any breach of any representation
        or
        warranty with respect to the Mortgage Loans (except as set forth in Section
        2.03(a)(vi)) under any circumstances.

       

      Section
        2.04. Discovery
        of Breach.

      

      
        
          
            
            

          

          
            70

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      Section
        2.05. Repurchase,
        Purchase or Substitution of Mortgage Loans.

       

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

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

       

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

       

      Section
        2.06. Grant
        Clause.

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

      THE
        CERTIFICATES

       

      Section
        3.01. The
        Certificates.

       

      (a) The
        Certificates shall be issuable in registered form only and shall be securities
        governed by Article 8 of the New York Uniform Commercial Code. The Book-Entry
        Certificates will be evidenced by one or more certificates, beneficial ownership
        of which will be held in the dollar denominations in Certificate Principal
        Amount or Notional Principal Amount or in the Percentage Interests, specified
        herein. Each Class of Book-Entry Certificates shall be issued in the minimum
        denominations in Certificate Principal Amount (or Notional Amount) or Percentage
        Interest specified in the Preliminary Statement hereto and in integral multiples
        of $1 or 5% (in the case of Certificates issued in Percentage Interests)
        in
        excess thereof. Each Class of Non-Book Entry Certificates other than the
        Residual Certificate shall be issued in definitive, fully registered form
        in the
        minimum denominations in Certificate Principal Amount (or Notional Amount)
        specified in the Preliminary Statement hereto and in integral multiples of
        $1 in
        excess thereof. The Class R-II Certificate shall be issued as a single
        Certificate and maintained in definitive, fully registered form in a minimum
        denomination equal to $100. Each of the Class P and Class X Certificates
        shall
        be maintained in definitive, fully registered form in a minimum denomination
        equal to 25% of the Percentage Interest of such Class of Certificates. The
        Certificates may be issued in the form of typewritten certificates. One
        Certificate of each Class of Certificates other than any Class of Residual
        Certificates may be issued in any denomination in excess of the minimum
        denomination.

      

      
        
          
            
            

          

          
            73

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      (c) The
        Class
        B4-II, Class B5-II or Class B6-II Certificates offered and sold in reliance
        on
        the exemption from registration under Rule 144A under the Act shall be issued
        initially in the form of one or more permanent global Certificates in
        definitive, fully registered form without interest coupons with the applicable
        legends set forth in Exhibit A added to the forms of such Certificates (each,
        a
“Restricted Global Security”), which shall be deposited on behalf of the
        subscribers for such Certificates represented thereby with the Trustee, as
        custodian for DTC and registered in the name of a nominee of DTC, duly executed
        and authenticated by the Trustee or the Authenticating Agent as hereinafter
        provided. The aggregate principal amounts of the Restricted Global Securities
        may from time to time be increased or decreased by adjustments made on the
        records of the Trustee or DTC or its nominee, as the case may be, as hereinafter
        provided.

       

      The
        Class
        B4-II, Class B5-II or Class B6-II Certificates sold in offshore transactions
        in
        reliance on Regulation S shall be issued initially in the form of one or
        more
        permanent global Certificates in definitive, fully registered form without
        interest coupons with the applicable legends set forth in Exhibit A hereto
        added
        to the forms of such Certificates (each, a “Regulation S Global Security”),
        which shall be deposited on behalf of the subscribers for such Certificates
        represented thereby with the Trustee, as custodian for DTC and registered
        in the
        name of a nominee of DTC, duly executed and authenticated by the Trustee
        and the
        Authenticating Agent as hereinafter provided. The aggregate principal amounts
        of
        the Regulation S Global Securities may from time to time be increased or
        decreased by adjustments made on the records of the Trustee or DTC or its
        nominee, as the case may be, as hereinafter provided.

       

      (d) The
        Class
        B4-II, Class B5-II or Class B6-II Certificates sold to an “accredited investor”
complying with the transfer provision set forth in Section 3.03 under Rule
        501(a)(1), (2), (3) or (7) under the Act shall be issued initially in the
        form
        of one or more Definitive Certificates.

       

      Section
        3.02. Registration.

      

      
        
          
            
            

          

          
            74

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      Section
        3.03. Transfer
        and Exchange of Certificates.

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            75

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      (i) The
        Certificate Registrar shall register the transfer of a Restricted Certificate
        if
        the requested transfer is (x) to the Depositor or the Placement Agent, an
        affiliate (as defined in Rule 405 under the Act) of the Depositor or the
        Placement Agent or (y) being made to a QIB by a transferor that has provided
        the
        Certificate Registrar with a certificate in the form of Exhibit F hereto;
        and

       

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

       

      (d) 
        No
        transfer of an ERISA-Restricted Swap Certificate shall be registered unless
        the
        Trustee and the Certificate Registrar shall have received a representation
        substantially in the form of Exhibit H hereto that either (i) the transferee
        is
        not, and is not acting for, on behalf of or with any assets of, an employee
        benefit plan or other arrangement subject to Title I of ERISA or plan subject
        to
        Section 4975 of the Code, or (ii) until the termination of the Swap Agreement,
        the acquisition and holding of such Certificate will
        not
        constitute or result in a nonexempt prohibited transaction under Title I
        of
        ERISA or Section 4975 of the Code.

       

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

      

      
        
          
            
            

          

          
            76

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

      

      
        
          
            
            

          

          
            77

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            78

            
              

            

          

          
            
            

          

        

      

      

       

      If
        any
        purported transferee shall become a registered Holder of a Residual Certificate
        in violation of the provisions of this Section 3.03(f), then upon receipt
        of
        written notice to the Trustee or the Certificate Registrar that the registration
        of transfer of such Residual Certificate was not in fact permitted by this
        Section 3.03(f), the last preceding Permitted Transferee shall be restored
        to
        all rights as Holder thereof retroactive to the date of such registration
        of
        transfer of such Residual Certificate. Neither the Trustee nor the Certificate
        Registrar shall be under any liability to any Person for any registration
        of
        transfer of a Residual Certificate that is in fact not permitted by this
        Section
        3.03(f), for making any payment due on such Certificate to the registered
        Holder
        thereof or for taking any other action with respect to such Holder under
        the
        provisions of this Agreement so long as the transfer was registered upon
        receipt
        of the affidavit described in the preceding paragraph of this Section
        3.03(f).

       

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

       

      (h) Notwithstanding
        any provision to the contrary herein, so long as a Global Security representing
        any of the Class B4-II, Class B5-II or Class B6-II Certificates remains
        outstanding and is held by or on behalf of DTC, transfers of a Global Security
        representing any such Certificates, in whole or in part, shall only be made
        in
        accordance with Section 3.01 and this Section 3.03(h).

       

      (i) Subject
        to clauses (ii) and (iii) of this Section 3.03(h), transfers of a Global
        Security representing any of the Class B4-II, Class B5-II or Class B6-II
        Certificates shall be limited to transfers of such Global Security, in whole
        or
        in part, to nominees of DTC or to a successor of DTC or such successor’s
        nominee.

       

      (ii) Restricted
        Global Security to Regulation S Global Security.
        If a
        holder of a beneficial interest in a Restricted Global Security deposited
        with
        or on behalf of DTC wishes at any time to exchange its interest in such
        Restricted Global Security for an interest in a Regulation S Global Security,
        or
        to transfer its interest in such Restricted Global Security to a Person who
        wishes to take delivery thereof in the form of an interest in a Regulation
        S
        Global Security, such holder, provided such holder is not a U.S. person,
        may,
        subject to the rules and procedures of DTC, exchange or cause the exchange
        of
        such interest for an equivalent beneficial interest in the Regulation S Global
        Security. Upon receipt by the Certificate Registrar, of (I) instructions
        from
        DTC directing the Certificate Registrar, to be credited a beneficial interest
        in
        a Regulation S Global Security in an amount equal to the beneficial interest
        in
        such Restricted Global Security to be exchanged but not less than the minimum
        denomination applicable to such holder’s Certificates held through a Regulation
        S Global Security, (II) a written order given in accordance with DTC’s
        procedures containing information regarding the participant account of DTC
        and,
        in the case of a transfer pursuant to and in accordance with Regulation S,
        the
        Euroclear or Clearstream account to be credited with such increase and (III)
        a
        certificate in the form of Exhibit L-1 hereto given by the holder of such
        beneficial interest stating that the exchange or transfer of such interest
        has
        been made in compliance with the transfer restrictions applicable to the
        Global
        Securities, including that the holder is not a U.S. person, and pursuant
        to and
        in accordance with Regulation S, the Certificate Registrar, shall reduce
        the
        principal amount of the Restricted Global Security and increase the principal
        amount of the Regulation S Global Security by the aggregate principal amount
        of
        the beneficial interest in the Restricted Global Security to be exchanged,
        and
        shall instruct Euroclear or Clearstream, as applicable, concurrently with
        such
        reduction, to credit or cause to be credited to the account of the Person
        specified in such instructions a beneficial interest in the Regulation S
        Global
        Security equal to the reduction in the principal amount of the Restricted
        Global
        Security.

      

      
        
          
            
            

          

          
            79

            
              

            

          

          
            
            

          

        

      

      

       

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

      

      
        
          
            
            

          

          
            80

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

      Section
        3.04. Cancellation
        of Certificates.

       

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

       

      Section
        3.05. Replacement
        of Certificates.

       

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

       

      Section
        3.06. Persons
        Deemed Owners.

       

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

      

      
        
          
            
            

          

          
            81

            
              

            

          

          
            
            

          

        

      

      

       

      Section
        3.07. Temporary
        Certificates.

       

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

       

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

       

      Section
        3.08. Appointment
        of Paying Agent.

       

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

       

      (b) Any
        Paying Agent shall be either a bank or trust company or otherwise authorized
        under law to exercise corporate trust powers. A Paying Agent shall comply
        with
        its reporting obligations under Regulation AB with respect to the Trust Fund
        in
        form and substance similar to those of the Trustee pursuant to Section 6.20
        and
        Section 9.25, and the related assessment of compliance and attestation shall
        cover, at a minimum, the matters indicated as obligations with respect to
        the
        Paying Agent on Exhibit O attached hereto. In addition, the Paying Agent
        (if
        other than the Trustee) shall notify the Sponsor, the Master Servicer and
        the
        Depositor within five (5) calendar days of knowledge thereof (i) of any legal
        proceedings pending against the Paying Agent of the type described in Item
        1117
        (§ 229.1117) of Regulation AB, (ii) any merger, consolidation or sale of
        substantially all of the assets of the Paying Agent and (iii) if the Paying
        Agent shall become (but only to the extent not previously disclosed) at any
        time
        an Affiliate of any of the parties listed on Exhibit R hereto or any of their
        Affiliates.

      

      
        
          
            
            

          

          
            82

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      Section
        3.09. Book-Entry
        Certificates.

       

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

       

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

       

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

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            83

            
              

            

          

          
            
            

          

        

      

      

       

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

      (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

      (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.

        and

        (H) of paragraph (i) of the definition thereof (other than any amounts due
        or
        reimbursable to the Trustee or the Custodians pursuant to this Agreement),
        shall
        be remitted to the Trustee for deposit into the Certificate Account by wire
        transfer in immediately available funds. The Master Servicer, at its option
        (but
        with prior notice to Trustee), may choose to make daily remittances from
        the
        Collection Account to the Trustee for deposit into the Certificate
        Account.

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

        due

        of
        the amount permitted to be withdrawn or withheld from the Collection Account
        in
        accordance with Sections 5.04 and 9.21;

        to be withdrawn or withheld from the Collection Account in accordance with
        Sections 5.04 and 9.21; 

       

      (iv) all
        Insurance Proceeds;

       

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

       

      (vi) all
        Prepayment Penalty Amounts;

        Loan repurchased by the Depositor, the Seller, the Master Servicer or any
        other
        Person, and any Substitution Amount related to any Qualifying Substitute
        Mortgage Loan and any purchase price paid by any NIMS Insurer for the purchase
        of any Distressed Mortgage Loan under Section 7.04. 

      

      
        
          
            
            

          

          
            85

            
              

            

          

          
            
            

          

        

      

      

       

      (e) Funds
        in
        the Collection Account may be invested in Eligible Investments (selected
        by and
        at the written direction of the Master Servicer) which shall mature not later
        than one Business Day prior to the Deposit Date (except that if such Eligible
        Investment is an obligation of the Trustee or the Paying Agent, if other
        than
        the Trustee, and such Collection Account is maintained with the Trustee or
        the
        Paying Agent, if other than the Trustee, then such Eligible Investment shall
        mature not later than such applicable Deposit Date), and any such Eligible
        Investment shall not be sold or disposed of prior to its maturity. All such
        Eligible Investments shall be made in the name of the Master Servicer in
        trust
        for the benefit of the Trustee and Holders of Structured Adjustable Rate
        Mortgage Loan Trust, Mortgage Pass-Through Certificates, Series 2007-2. All
        income and gain realized from any such investment shall be for the benefit
        of
        the Master Servicer, while such Collection Account is maintained by the Master
        Servicer, and shall be subject to its withdrawal or order from time to time
        and
        shall not be part of the Trust Fund. The amount of any losses incurred in
        respect of any such investments shall be deposited in such Collection Account
        by
        the Master Servicer out of its own funds, without any right of reimbursement
        therefor, immediately as realized. The foregoing requirements for deposit
        in the
        Collection Account are exclusive, it being understood and agreed that, without
        limiting the generality of the foregoing, payments of interest on funds in
        the
        Collection Account and payments in the nature of late payment charges or
        assumption fees need not be deposited by the Master Servicer in the Collection
        Account and may be retained by the Master Servicer or the applicable Servicer
        as
        additional servicing compensation. If the Master Servicer deposits in the
        Collection Account any amount not required to be deposited therein, it may
        at
        any time withdraw such amount from such Collection Account.

       

      Section
        4.02. Application
        of Funds in the Collection Account.

       

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

       

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

       

      (ii) to
        reimburse itself or any Servicer for any Advances or Servicing Advances made
        by
        it or by such Servicer that it or such Servicer determines in good faith
        will
        not be recoverable from amounts representing late recoveries of payments
        of
        principal or interest respecting the particular Mortgage Loan as to which
        such
        Advance or Servicing Advance was made or from Liquidation Proceeds or Insurance
        Proceeds with respect to such Mortgage Loan, it being understood, in the

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

       

      (iv) in
        the
        event it has elected not to pay itself the Master Servicing Fee out of any
        Mortgagor payment on account of interest or other recovery with respect to

        Fee
        for each Distribution Date and any unpaid Master Servicing Fees for prior
        Distribution Dates, as reduced pursuant to Section 5.05, from any Mortgagor

        or
        9.22(a) or pursuant to the applicable Servicing Agreement (to the extent

        reimbursement constitutes “unanticipated expenses” within the meaning of
        Treasury Regulation Section 1.860G-1(b)(3)(ii)), and to reimburse itself
        for any

            87

            
              

            

          

          
            
            

          

        

      

      

       

      (ix) to

        payment to itself, the Trustee and others pursuant to any provision of this
        Agreement;

        to
        this Agreement, all amounts received thereon and not distributed on the date
        on
        which the related prepurchase was effected, and to pay the applicable person
        any
        Advances and Servicing Advances to the extent specified in the definition
        of
        Purchase Price (or FPD Purchase Price in the case of a First Payment Default
        Loan);

       

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

       

      (xii) to
        clear
        and terminate any Collection Account pursuant to Section 7.02;

       

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

       

      (xiv) to
        reimburse any Servicer for such amounts as are due thereto under the applicable
        Servicing Agreement and have not been retained by or paid to such Servicer
        to
        the extent provided in such Servicing Agreement provided such amounts are
        Servicing Fees or “unanticipated expenses” within the meaning of Treasury
        Regulation Section 1.860G-1(b)(3)(ii).

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            88

            
              

            

          

          
            
            

          

        

      

      

       

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

        completeness of the information or data (i) regarding the Mortgage Loans
        (including any Early Payment Default Mortgage Loans) and the related REO
        Property that has been provided to the Master Servicer by the Servicer and
        (ii)
        regarding the Pool 1 Interest Rate Cap Agreement and the Swap Agreement that
        has
        been provided to the Trustee by the Cap Counterparty and the Swap Counterparty,
        respectively. The Trustee shall be entitled to conclusively rely on the accuracy
        and completeness of (i) the Mortgage Loan data provided by the Master Servicer
        and shall have no liability for any errors or omissions in such Mortgage
        Loan
        data or other information, (ii) the Master Servicer shall have no liability
        for
        any errors or omissions in such mortgage loan data or information, and (iii)
        the
        information and data provided to the Trustee by the Cap Counterparty and
        Swap
        Counterparty, and, in each case, the Trustee shall not be obligated to verify,
        reconcile, recomputed or recalculate any such information or 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 the NIM Securities or an investment
        in the Certificates; provided, however, that the Master Servicer shall be
        entitled to be reimbursed by such Certificateholder for such Master Servicer’s
        actual expenses incurred in providing such reports and access.

       

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

      

      
        
          
            
            

          

          
            92

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      Section
        4.04. Certificate
        Account.

       

      (a) The
        Trustee shall establish and maintain in its name, as trustee, a trust account
        (the “Certificate Account”), entitled Wells Fargo Bank, N.A. as Trustee in trust
        for the holders of Structured Adjustable Rate Mortgage Loan Trust Mortgage
        Pass-Through Certificates, Series 2007-2, to be held in trust for the benefit
        of
        the Certificateholders until disbursed pursuant to the terms of this Agreement.
        The Certificate Account shall be an Eligible Account. If the existing
        Certificate Account ceases to be an Eligible Account, the Trustee shall
        establish a new Certificate Account that is an Eligible Account within 20
        Business Days and transfer all funds on deposit in such existing Certificate
        Account into such new Certificate Account. The Certificate Account shall
        relate
        solely to the Certificates issued hereunder and funds in the Certificate
        Account
        shall be held separate and apart from and shall not be commingled with any
        other
        monies including, without limitation, other monies of the Trustee held under
        this Agreement.

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            93

            
              

            

          

          
            
            

          

        

      

      

       

      (iii) to
        make
        payments of the Master Servicing Fee (to the extent not already withheld
        or
        withdrawn from the Collection Account by the Master Servicer) to the Master
        Servicer;

       

      (iv) to
        make
        distributions to the Certificateholders pursuant to Article V; and

       

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

       

      (c) The
        Trustee may invest, or cause to be invested, funds held in the Certificate
        Account, which funds, if invested, shall be invested in Eligible Investments
        (which may be obligations of the Trustee). All such investments must mature
        no
        later than the next Distribution Date, and shall not be sold or disposed
        of
        prior to their maturity. All such Eligible Investments will be made in the name
        of the Trustee (in its capacity as such) or its nominee. All income and gain
        realized from any such investment shall be paid to the Trustee and shall
        be
        subject to its withdrawal on order from time to time. The amount of any losses
        incurred in respect of any such investments shall be paid by the Trustee
        for
        deposit in the Certificate Account out of its own funds, without any right
        of
        reimbursement therefor, immediately as realized. Funds held in the Certificate
        Account that are not invested shall be held in cash.

       

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

       

      ARTICLE
        V

       

      DISTRIBUTIONS
        TO HOLDERS OF CERTIFICATES

       

      Section
        5.01. Distributions
        Generally.

       

      (a) Subject
        to Section 7.01 with respect to the final distribution on the Certificates,
        on
        each Distribution Date the Trustee (or any Paying Agent) shall make
        distributions in accordance with this Article V. Such distributions shall
        be
        made by wire transfer if the Certificateholder has provided the Trustee with
        wire instructions or by check mailed to the address of such Certificateholder
        as
        it appears in the books of the Trustee if the Certificateholder has not provided
        the Trustee with wire instructions in
        immediately available funds to an account specified in the request and at
        the
        expense of such Certificateholder; provided, however, that the final
        distribution in respect of any Certificate shall be made only upon presentation
        and surrender of such Certificate at the Corporate Trust Office. Wire transfers
        may be made at the expense of the Holder requesting such wire transfer by
        deducting a wire transfer fee from the related distribution. Notwithstanding
        such final payment of principal of any of the Certificates, each Residual
        Certificate will remain outstanding until the termination of each REMIC and
        the
        payment in full of all other amounts due with respect to the Residual
        Certificate and at such time such final payment in retirement of the Residual
        Certificate will be made only upon presentation and surrender of such
        Certificate at the Corporate Trust Office of the Certificate Registrar. If
        any
        payment required to be made on the Certificates is to be made on a day that
        is
        not a Business Day, then such payment will be made on the next succeeding
        Business Day.

      

      
        
          
            
            

          

          
            94

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

      Section
        5.02. Distributions
        from the Certificate Account.

       

      (a) On
        each
        Distribution Date, the Trustee (or any successor Paying Agent on behalf of
        the
        Trustee, as applicable) shall withdraw from the Certificate Account the Total
        Distribution Amount (excluding all Prepayment Penalty Amounts) and shall
        allocate such amount to the interests issued in respect of each REMIC and
        shall
        distribute such amount as specified in this Section. 

       

      (b) On
        each
        Distribution Date (or, with respect to clause (ii) below, on the related
        Swap
        Payment Date), the Trustee (or Paying Agent, as applicable) shall distribute
        the
        Interest Remittance Amount for Pool 1 as follows:

       

      (i) to
        the
        Trustee, the payment of the Trustee Fee allocable to Pool 1 for such

      (ii) for
        deposit into the Supplemental Interest Trust Account, any Net Swap Payment
        or
        Swap Termination Payment (not due to a Swap Counterparty Trigger Event) owed
        to
        the Swap Counterparty (including amounts remaining unpaid from previous
        Distribution Dates);

       

      (iii) concurrently,
        pro rata, to the Pool 1 Senior Certificates, Current Interest and any
        Carryforward Interest for such classes for such Distribution Date (any shortfall
        in Current Interest and Carryforward Interest to be allocated between such
        Classes in proportion to the amount of Current Interest and Carryforward
        Interest that would otherwise be distributable thereon);

       

      (iv) 
        to the
        Pool 1 Subordinate Certificates in accordance with the Pool 1 Subordinate
        Priority, Current Interest and Carryforward Interest for such classes for
        such
        Distribution Date; and

      

      
        
          
            
            

          

          
            95

            
              

            

          

          
            
            

          

        

      

      

       

      (v) for
        application as part of Monthly Excess Cashflow for such Distribution Date,
        pursuant to Section 5.02(e) below, any such Interest Remittance Amount for
        Pool
        1 remaining undistributed for such Distribution Date.

       

      (c) The
        Principal Distribution Amount for Pool 1 will be distributed on each
        Distribution Date (or, with respect to clause (i)(B) below, on the related
        Swap
        Payment Date), as follows:

       

      (i) On
        each
        Distribution Date (a) prior to the Pool 1 Stepdown Date or (b) on or after
        the
        Pool 1 Stepdown Date and with respect to which a Pool 1 Trigger Event is
        in
        effect, until the aggregate Certificate Principal Amount of the Pool 1 Senior
        Certificates equals the Pool 1 Target Amount for such Distribution Date,
        the
        Trustee shall distribute the Principal Distribution Amount for Pool 1 in

        Class Principal Amount of such Class has been reduced to zero.

       

      Notwithstanding
        the foregoing, the first $0.96 of principal portion of Realized Losses in
        Pool 2
        shall not be allocated to any Class of Certificates.

       

      (b) With
        respect to any Distribution Date, the principal portion of any Excess Loss
        in
        respect of a Mortgage Loan shall be allocated if such Mortgage Loan is in
        Pool
        2, pro
        rata,
        to the
        Pool 2 Senior Certificates and the Pool 2 Subordinate Certificates; provided,
        that any such loss allocated to any Class of Accrual Certificates shall be
        allocated (subject to Section
        5.03(c)) on the basis of the lesser of (x) the Class Principal Amount thereof
        immediately prior to the applicable Distribution Date and (y) the Class
        Principal Amount thereof on the Closing Date (as reduced by any Realized
        Losses
        previously allocated thereto).

       

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

       

      (d) Pool
        1
        Applied Loss Amounts or 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, amounts described in clauses (x) and (y) of the definition
        of
        Subordinate Certificate Writedown Amount for such date shall effect
        corresponding reductions in the Class Principal Amount of the lowest ranking
        Class of outstanding Pool 2 Subordinate Certificates, which reductions shall
        occur on such Distribution Date after giving effect to distributions made
        on
        such Distribution Date.

       

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

      

      
        
          
            
            

          

          
            108

            
              

            

          

          
            
            

          

        

      

      

       

      (a) Advances
        shall be made in respect of each Deposit Date as provided herein. If, on
        any
        Determination Date, the Master Servicer determines that any Scheduled Payments
        due during the related Due Period (other than Balloon Payments) have not
        been
        received, the Master Servicer shall, or shall cause the applicable Servicer
        to,
        advance such amount on the Deposit Date immediately following such Determination
        Date, less an amount, if any, to be set forth in an Officer’s Certificate to be
        delivered to the Trustee on such Determination Date, which if advanced the
        Master Servicer or such Servicer has determined would not be recoverable
        from
        amounts received with respect to such Mortgage Loan, including late payments,
        Liquidation Proceeds, Insurance Proceeds or otherwise. The Trustee shall
        be able
        to rely conclusively on any non-recoverability determination made by the
        Master
        Servicer. If the Master Servicer determines that an Advance is required,
        it
        shall on the Deposit Date immediately following such Determination Date either
        (i) remit to the Trustee from its own funds (or funds advanced by the applicable
        Servicer) for deposit in the Certificate Account immediately available funds
        in
        an amount equal to such Advance, (ii) cause to be made an appropriate entry
        in
        the records of the Collection Account that funds in such account being held
        for
        future distribution or withdrawal have been, as permitted by this Section
        5.04,
        used by the Master Servicer to make such Advance, and remit such immediately
        available funds to the Trustee for deposit in the Certificate Account or
        (iii)
        make Advances in the form of any combination of clauses (i) and (ii) aggregating
        the amount of such Advance. Any funds being held in the Collection Account
        for
        future distribution to Certificateholders and so used shall be replaced by
        the
        Master Servicer from its own funds by remittance to the Trustee for deposit
        in
        the Certificate Account on or before any future Deposit Date to the extent
        that
        funds in the Certificate Account on such Deposit Date shall be less than
        payments to Certificateholders required to be made on the related Distribution
        Date. The Trustee shall be entitled to conclusively rely upon any determination
        by the Master Servicer that an Advance, if made, would constitute a
        non-recoverable advance. The Master Servicer and each Servicer shall be entitled
        to be reimbursed from the Collection Account for all Advances made by it
        as
        provided in Section 4.02.

       

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

       

      Section
        5.05. Compensating
        Interest Payments.

       

      The
        Master Servicer shall not be responsible for making any Compensating Interest
        Payments not made by the Servicers. Any Compensating Interest Payments on
        Pool 2
        Mortgage Loans made by the Servicers shall be a component of the Available
        Distribution Amount. Any Compensating Interest Payments on Pool 1 Mortgage
        Loans
        made by the Servicers shall be a component of the Interest Remittance
        Amount.

      

      
        
          
            
            

          

          
            109

            
              

            

          

          
            
            

          

        

      

      

       

      Section
        5.06. Funding
        Account.

       

      (a) No
        later
        than the Closing Date, the Trustee shall establish and maintain a segregated
        trust account that is an Eligible Account, which shall be titled “Funding
        Account, U.S Bank National Association as trustee, in trust for the registered
        holders of Structured Adjustable Rate Mortgage Loan Trust Mortgage Pass-Through
        Certificates Series 2007-2” (the “Funding Account”). The Trustee shall, promptly
        upon receipt, deposit in the Funding Account and retain therein the Funding
        Amount remitted on the Closing Date to the Trustee by the Depositor. As of
        the
        closing date, the amount of $963,082.09 was deposited into the Funding Account.
        Funds deposited in the Funding Account shall be held in trust by the Trustee
        on
        behalf of the Certificateholders for the uses and purposes set forth herein.
        On
        the Distribution Date in March 2007, the Trustee will withdraw from the Funding
        Account an amount equal to the Funding Amount. The Trustee shall pay (i)
        the
        Funding Amount with respect to Pool 1 to the Certificateholders in accordance
        with the priorities set forth in Section 5.02 as if the interest portion
        of such
        amounts were included in the Interest Remittance Amount for Pool 1 and as
        if the
        principal portion of such amounts were included in the Principal Remittance
        Amount for Pool 1 and (ii) the Funding Amount with respect to Pool 2 to the
        Certificateholders in accordance with the priorities set forth in Section
        5.02
        as if such amounts were included in the Available Distribution Amount of
        Pool 2,
        provided, however, that the Trustee shall not be entitled to any payment
        pursuant to Sections 5.02(b)(i) or 5.02(c)(i)(A) with respect to the Funding
        Amount.

       

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

       

      (c) On
        the
        Distribution Date in March 2007, any amounts remaining on deposit in the
        Funding
        Account after withdrawals pursuant to paragraph (a) above shall be withdrawn
        by
        the Trustee and paid to the Depositor or its designee and the Trustee shall
        terminate the Funding Account on such first Distribution Date.

       

      (d) For
        purposes of computations throughout this Agreement (other than for purposes
        of
        computing any fee or the Net WAC of any Pool or portion thereof), (i) Pool
        1
        shall be deemed to include certain Mortgage Loans with a Scheduled Principal
        Balance as of the Cut-off Date of $540,000.00
        that
        are
        prepaid in full on the Closing Date such that their Scheduled Principal Balance
        for all Distribution Dates is $0 and (ii) Pool
        2
        shall be deemed to include certain Pool 2 Mortgage Loans with a Scheduled
        Principal Balance as of the Cut-off Date of $417,891.88
        that
        are
        prepaid in full on the Closing Date such that their Scheduled Principal Balance
        for all Distribution Dates is $0.

      Section
        5.07. Basis
        Risk Reserve Funds.

       

      (a) On
        the
        Closing Date, the Trustee shall establish and maintain in its name, and on
        behalf of the Trust Fund, in trust for the benefit of the holders of the
        Pool 1
        Certificates, the Pool 1 Basis Risk Reserve Fund. In addition, the Trustee
        shall
        hold on behalf of the Trust Fund, the Pool 1 Interest Rate Cap Agreement
        as an
        asset in the Pool 1 Basis Risk Reserve Fund. The Pool 1 Basis Risk Reserve
        Fund
        shall be an Eligible Account, and funds on deposit therein shall be held
        separate and apart from, and shall not be commingled with, any other moneys,
        including, without limitation, other moneys of the Trustee held pursuant
        to this
        Agreement.

       

      (b) On
        each
        Distribution Date on which there is a payment received under the Pool 1 Interest
        Rate Cap Agreement that is based on a notional amount in excess of the aggregate
        Class Principal Amount of the Pool 1 Certificates (such amount, the “C-X
        Component Excess Cap Amount”), the Trustee shall distribute such C-X Component
        Excess Cap Amount to the Class X Certificateholders in respect of the C-X
        Component pursuant to Section 5.02(e)(iv). On each Distribution Date the
        Trustee
        shall distribute in the order of priority and to the extent specified in
        Section
        5.02(e)(iv) of this Agreement the sum of (without duplication) (a) any payments
        made by the Cap Counterparty to the Trust Fund for such Distribution Date
        with
        respect to the Pool 1 Interest Rate Cap Agreement and (b) any amounts then
        on
        deposit in the Pool 1 Basis Risk Reserve Fund, including any earnings thereon.
        On any Distribution Date, any amounts that the Trustee is not required to
        distribute from the Pool 1 Basis Risk Reserve Fund pursuant to Section
        5.02(e)(iv)of this Agreement shall remain on deposit in the Pool 1 Basis
        Risk
        Reserve Fund.

       

      (c) Funds
        in
        the Pool 1 Basis Risk Reserve Fund shall be invested in Eligible Investments.
        The C-X Component of the Class X Certificates shall evidence ownership of
        the
        portion of the Pool 1 Basis Risk Reserve Fund related to the Pool 1 Interest
        Rate Cap Agreement for federal income tax purposes and LBH on behalf of the
        Holders thereof shall direct the Trustee, in writing, as to investment of
        amounts on deposit therein. LBH shall be liable for any losses incurred on
        such
        investments. In the absence of written instructions from LBH as to investment
        of
        funds on deposit in the Pool 1 Basis Risk Reserve Fund, such funds shall
        remain
        uninvested. The Pool 1 Basis Risk Reserve Fund will be terminated after the
        termination of the Trust Fund pursuant to Article VII.

       

      Section
        5.08. Supplemental
        Interest Trust.

       

      (a) A
        separate trust is hereby established (the “Supplemental Interest Trust”), the
        corpus of which shall be held by the Trustee, on behalf of the Trust Fund,
        for
        the benefit of the holders of the Certificates and the Swap Counterparty.
        The
        Trustee, as trustee of the Supplemental Interest Trust, shall establish an
        account (the “Supplemental Interest Trust Account”). The Supplemental Interest
        Trust Account shall be an Eligible Account, and funds on deposit therein
        shall
        be held separate and apart from, and shall not be commingled with, any other
        moneys, including, without limitation, other moneys of the Trustee held pursuant
        to this Agreement. 

      

      
        
          
            
            

          

          
            111

            
              

            

          

          
            
            

          

        

      

      

       

      (b) The
        Trustee shall deposit into the Supplemental Interest Trust Account any Net
        Swap
        Payment required pursuant to Sections 5.02(b)(ii), 5.02(c)(i)(B) and
        5.02(c)(ii)(B), any Swap Termination Payment required pursuant to Sections
        5.02(b)(ii), 5.02(c)(i)(B) and 5.02(c)(ii)(B), any amounts received from
        the
        Swap Counterparty under the Swap Agreement and any amounts required pursuant
        to
        Section 5.02(e)(vii), and shall distribute from the Supplemental Interest
        Trust
        Account any Net Swap Payment required pursuant to Section 5.02(f)(i) or Swap
        Termination Payment required pursuant to Sections 5.02(f)(ii) and
        (x).

       

      (c) Funds
        in
        the Supplemental Interest Trust Account shall be invested in Eligible
        Investments. Any earnings on such amounts shall be distributed on each
        Distribution Date pursuant to Section 5.02(f). The S-X Component of the Class
        X
        Certificates shall evidence ownership of the Supplemental Interest Trust
        Account
        for federal income tax purposes and the Holder thereof shall direct the Trustee,
        in writing, as to investment of amounts on deposit therein. The Class X
        Certificateholders shall be liable for any losses incurred on such investments.
        In the absence of written instructions from the Class X Certificateholders
        as to
        investment of funds on deposit in the Supplemental Interest Trust Account,
        such
        funds shall be invested in the Wells Fargo Advantage Prime Money Market Fund
        or
        comparable investment vehicle. Any amounts on deposit in the Supplemental
        Interest Trust Account in excess of the Supplemental Interest Trust Amount
        on
        any Distribution Date shall be held for distribution pursuant to Section
        5.02(f)
        on the following Distribution Date.

       

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

       

      (e) (Reserved)

       

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

       

      Section
        5.09. Collateral
        Account.

       

      In
        the
        event that the Swap Counterparty is required to post collateral pursuant
        to a
        downgrade event under the Swap Agreement, the Trustee, on behalf of the Trust
        Fund, is hereby authorized to establish on the Closing Date, a Collateral
        Account for the deposit of such monies. Funds in the Collateral Account shall
        not be commingled with any other monies and shall not be invested. Funds
        in the
        Collateral Account will be administered pursuant to the Credit Support Annex
        of
        the Swap Agreement. The Collateral Account shall not be an asset of any REMIC.
        On the first Distribution Date immediately following any Swap Payment Date
        as to
        which a shortfall exists with respect to a Net Swap Payment or a Swap
        Termination Payment owed by the Swap Counterparty as a result of its failure
        to
        make payments pursuant to the Swap Agreement, amounts necessary to cover
        such
        shortfall shall be removed from the Collateral Account and distributed as
        all or
        a portion of such Net Swap Payment or Swap Termination Payment pursuant to
        Section 5.02.

       

      Section
        5.10. Rights
        of Swap Counterparty.
        

      

        
          
            
            

          

          
            112

            
              

            

          

          
            
            

          

        

      The
        Swap
        Counterparty shall be deemed a third-party beneficiary of this Agreement
        to the
        same extent as if it were a party hereto and shall have the right, upon
        designation of an “Early Termination Date” (as defined in the Swap Agreement),
        to enforce its rights under this Agreement, which rights include but are
        not
        limited to the obligation of the Trustee (A) to deposit any Net Swap Payment
        required pursuant to Sections 5.02(b)(ii), 5.02(c)(i)(B) and 5.02(c)(ii)(B),
        and
        any Swap Termination Payment required pursuant to Sections 5.02(b)(ii),
        5.02(c)(i)(B) and 5.02(c)(ii)(B), into the Supplemental Interest Trust Account,
        (B) to deposit any amounts required pursuant to Section 5.08(b) into the
        Supplemental Interest Trust Account, (C) to pay any Net Swap Payment required
        pursuant to Section 5.02(f)(i) or Swap Termination Payment required pursuant
        to
        Sections 5.02(f)(ii) and (x) to the Swap Counterparty and (D) to establish
        and
        maintain the Supplemental Interest Trust Account, to make such deposits thereto,
        investments therein and distributions therefrom as are required pursuant
        to
        Section 5.08. For the protection and enforcement of the provisions of this
        Section the Swap Counterparty shall be entitled to such relief as can be
        given
        either at law or in equity.

       

      Section
        5.11. Termination
        Receipts.
        

       

      In
        the
        event of an “Early Termination Event” as defined under the Swap Agreement, (i)
        any Swap Termination Payment made by the Swap Counterparty to the Supplemental
        Interest Trust and paid pursuant to Section 5.02(f)(ix) (“Termination Receipts”)
        will be deposited in a segregated non-interest bearing account which shall
        be an
        Eligible Account established by the Trustee (the “Termination Receipts Account”)
        and (ii) any amounts received from a replacement Swap Counterparty (“Replacement
        Receipts”) will be deposited in a segregated non-interest bearing account which
        shall be an Eligible Account established by the Trustee (the “Replacement
        Receipts Account”). The Trustee shall invest, or cause to be invested, funds
        held in the Termination Receipts Account and the Replacement Receipts Account
        in
        time deposits of the Trustee as permitted by clause (ii) of the definition
        of
        Eligible Investments or as otherwise directed in writing by a majority of
        the
        Certificateholders. All such investments must be payable on demand or mature
        on
        a Swap Payment Date or such other date as directed by the Certificateholders.
        All such Eligible Investments will be made in the name of the Trustee of
        the
        Supplemental Interest Trust (in its capacity as such) or its nominee. All
        income
        and gain realized from any such investment shall be deposited in the Termination
        Receipts Account or the Replacement Receipts Account, as applicable, and
        all
        losses, if any, shall be borne by the related account. The Trustee shall
        have no
        liability for losses on investments in Eligible Investments made pursuant
        to
        this Section 5.11 (other than as obligor on any such investments). 

       

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

       

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

      Section
        5.12. 1-X
        Component Account.

       

      (a) No
        later
        than the first date on which any NIM Securities are issued , the Trustee
        shall
        establish and maintain in its name, on behalf of the Trust Fund, for the
        benefit
        of the holders of the Class X Certificates, the 1-X Component Account and
        the
        Depositor may deposit a dollar amount into the 1-X Component Account. The
        1-X
        Component Account shall be an Eligible Account, and funds on deposit therein
        shall be held separate and apart from, and shall not be commingled with,
        any
        other moneys, including, without limitation, other moneys of the Trustee
        held
        pursuant to this Agreement.

       

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

       

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

       

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

      ARTICLE
        VI

       

      CONCERNING
        THE TRUSTEE; EVENTS OF DEFAULT

       

      Section
        6.01. Duties
        of Trustee.

       

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

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            115

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      (iii) With
        respect to amounts that would be treated as “unanticipated expenses” within the
        meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii) if paid or reimbursed
        by the REMICs hereunder, no provision of this Agreement shall require the
        Trustee 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 except, with respect to the Trustee,
        during such time, if any, as the Trustee shall be the successor to, and be
        vested with the rights, duties, powers and privileges of, the Master Servicer
        in
        accordance with the terms of this Agreement.

       

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

       

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

       

      (e) The
        Trustee shall not be personally liable with respect to any action taken,
        suffered or omitted to be taken by it in good faith in accordance with the
        direction of any NIMS Insurer or 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.

      

      
        
          
            
            

          

          
            116

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

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

       

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

       

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

       

      (l) For
        so
        long as the Depositor is subject to Exchange Act reporting requirements for
        the
        Structured Adjustable Rate Mortgage Loan Trust Mortgage Pass-Through
        Certificates, Series 2007-2, the Trustee
        shall give prior written notice to the Sponsor, the Master Servicer and the
        Depositor of the appointment of any Subcontractor by it and a written
        description (in form and substance satisfactory to the Sponsor and the
        Depositor) of the role and function of each Subcontractor utilized by the
        Trustee, specifying (A) the identity of each such Subcontractor and (B) which
        elements of the servicing criteria set forth under Item 1122(d) of Regulation
        AB
        will be addressed in assessments of compliance provided by each such
        Subcontractor.

        Custodial Agreement, of the Certificates (other than the certificate of
        authentication on the Certificates), or of any Mortgage Loan or Servicing
        Agreement, or related document save that the Trustee represents that, assuming
        due execution and delivery by the other parties hereto, this Agreement has
        been
        duly authorized, executed and delivered by it and constitutes its valid and
        binding obligation, enforceable against it in accordance with its terms except
        that such enforceability may be subject to (A) applicable bankruptcy and
        insolvency laws and other similar laws affecting the enforcement of the rights

        perfection or sufficiency of the security for the Certificates issued or
        intended to be issued hereunder. Except as otherwise provided herein, the
        Trustee shall not have any responsibility for filing any financing or
        continuation statement in any public office at any time or to otherwise perfect

        other
        capacity may become the owner or pledgee of Certificates and may transact
        banking and trust business with the other parties hereto with the same rights
        it
        would have if it were not Trustee or such agent.

        the Rating Agencies of any Class of Certificates with a rating or (vi) the
        Trustee shall fail to provide the information, reports or assessments or
        attestations required pursuant to Section 9.25 hereof, then the Depositor

        Insurer.

        acknowledge and deliver to the Depositor, the Master Servicer, any NIMS Insurer,
        the Swap Counterparty and to its predecessor trustee an instrument accepting
        such appointment hereunder, and thereupon the resignation or removal of the
        predecessor trustee shall become effective and such successor trustee without
        any further act, deed or conveyance, shall become fully vested with all the
        rights, powers, duties and obligations of its predecessor hereunder, with
        like
        effect as if originally named as trustee herein. The predecessor trustee
        shall
        deliver to the successor trustee (or assign to the successor trustee its
        interest under each Custodial Agreement, to the extent permitted thereunder)
        all
        Mortgage Files and documents and statements related to each Mortgage File
        held
        by it hereunder, and shall duly assign, transfer, deliver and pay over to

        effect such transfer and such of the record or copies thereof maintained
        by the
        predecessor trustee in the administration hereof as may be requested by the
        successor trustee and shall thereupon be discharged from all duties and
        responsibilities under this Agreement. In addition, the Master Servicer and
        the
        predecessor trustee shall execute and deliver such other instruments and
        do such
        other things as may reasonably be required to more fully and certainly vest
        and
        confirm in the successor trustee all such rights, powers, duties and
        obligations.

       

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

       

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

        or Consolidation of Trustee.

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

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

       

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

       

      (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:

      

      
        
          
            
            

          

          
            122

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

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

       

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

       

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

       

      (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.

      

      
        
          
            
            

          

          
            123

            
              

            

          

          
            
            

          

        

      

      

       

      (g) The
        Trust
        Fund shall pay the reasonable compensation of the co-trustees to the extent,
        and
        in accordance with the standards, specified in Section 6.12 hereof (which
        compensation shall not reduce any compensation payable to the Trustee under
        such
        Section).

       

      (h) Notwithstanding
        the foregoing, for so long as reports are required to be filed with the
        Commission under the Exchange Act with respect to the Trust, the Trustee
        shall
        not utilize any Subcontractor for the performance of its duties hereunder
        if
        such Subcontractor would be “participating in the servicing function” within the
        meaning of Item 1122 of Regulation AB without (a) giving notice to the Seller,
        the Master Servicer and the Depositor and (b) requiring any such Subcontractor
        to provide to the Trustee an assessment report as provided in Section 9.25(a)
        and an attestation report as provided in Section 9.25(b), which reports the
        Trustee shall include in its assessment and attestation reports, and to the
        extent such subcontractor is acting in a trust capacity, the information
        (as
        though such subcontractor was the Trustee) pursuant to Section 6.01(m) and
        6.20(e)(iv) for delivery by the Trustee thereunder,. The Trustee shall indemnify
        the Depositor, the Master Servicer and any director, officer, employee or
        agent
        of each of the Depositor and the Master Servicer, and hold them harmless
        against
        any and all claims, losses, damages, penalties, fines, forfeitures, reasonable
        and necessary legal fees and related costs, judgments, and any other costs,
        fees
        and expenses that any of them may sustain arising out of or based on the
        failure
        by the Trustee (i) to give notice of the engagement of any Subcontractor
        or (ii)
        to require any Subcontractor to provide the Trustee or fail to provide to
        the
        master Servicer and the Depositor the information, when and as required,
        pursuant to this section 6.09(h). This indemnity shall survive the termination
        of this Agreement or the earlier resignation or removal of the
        Trustee.

       

      Section
        6.10. Authenticating
        Agents.

       

      (a) The
        Trustee may appoint one or more Authenticating Agents which shall be authorized
        to act on behalf of the Trustee in authenticating Certificates. The Trustee
        hereby appoints the Trustee to act as the initial Authenticating Agent, and
        the
        Trustee hereby accepts such appointment. Notwithstanding anything to the
        contrary provided herein, wherever reference is made in this Agreement to
        the
        authentication of Certificates by the Trustee or the Trustee’s certificate of
        authentication, such reference shall be deemed to include authentication
        on
        behalf of the Trustee by an Authenticating Agent and a certificate of
        authentication executed on behalf of the Trustee by an Authenticating Agent.
        Each Authenticating Agent must be a corporation organized and doing business
        under the laws of the United States of America or of any state, having a
        combined capital and surplus of at least $15,000,000, authorized under such
        laws
        to do a trust business and subject to supervision or examination by federal
        or
        state authorities and acceptable to any NIMS Insurer, such consent shall
        not be
        unreasonably withheld.

       

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

      

      
        
          
            
            

          

          
            124

            
              

            

          

          
            
            

          

        

      

      

       

      (c) (c) Any
        Authenticating Agent may at any time resign by giving at least 30 days’ advance
        written notice of resignation to the Trustee, any NIMS Insurer and the
        Depositor. The Trustee may at any time terminate the agency of any
        Authenticating Agent by giving written notice of termination to such
        Authenticating Agent, any NIMS Insurer and the Depositor. Upon receiving
        a
        notice of resignation or upon such a termination, or in case at any time
        any
        Authenticating Agent shall cease to be eligible in accordance with the
        provisions of this Section 6.10, the Trustee may appoint a successor
        Authenticating Agent, shall give written notice of such appointment to the
        Depositor and any NIMS Insurer and shall mail notice of such appointment
        to all
        Holders of Certificates. Any successor Authenticating Agent upon acceptance
        of
        its appointment hereunder shall become vested with all the rights, powers,
        duties and responsibilities of its predecessor hereunder, with like effect
        as if
        originally named as Authenticating Agent. No successor Authenticating Agent
        shall be appointed unless eligible under the provisions of this Section 6.10. No
        Authenticating Agent shall have responsibility or liability for any action
        taken
        by it as such at the direction of the Trustee, provided that such action
        was
        undertaken without negligence or willful misconduct. Any Authenticating Agent
        shall be entitled to reasonable compensation for its services and, if paid
        by
        the Trustee, it shall be a reimbursable expense pursuant to Section
        6.12.

       

      Section
        6.11. Indemnification
        of Trustee.

       

      The
        Trustee and its respective directors, officers, employees and agents shall
        be
        entitled to indemnification from the Trust Fund for any loss, liability or
        expense incurred in connection with any legal proceeding or incurred without
        negligence or willful misconduct on their part, (it being understood that
        the
        negligence or willful misconduct of any Custodian shall not constitute
        negligence or willful misconduct on the part of the Trustee or its directors,
        officers, employees or agents for such purpose), arising out of, or in
        connection with, the acceptance or administration of the trusts created
        hereunder or in connection with the performance of their duties hereunder
        or
        under the Certificates, the Mortgage Loan Sale Agreement, the Pool 1 Interest
        Rate Cap Agreement, the Swap Agreement, any Custodial Agreement or any Servicing
        Agreement, including any applicable fees and expenses payable pursuant to
        Section 6.12 and the costs and expenses of defending themselves against any
        claim in connection with the exercise or performance of any of their powers
        or
        duties hereunder, provided that:

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            125

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

      Section
        6.12. Fees
        and Expenses of Trustee and Custodian.

       

      The
        Trustee shall be entitled to (a) receive, and is authorized to pay itself,
        the
        amount of income or gain earned from investment of funds in the Certificate
        Account and (b) reimbursement of all reasonable expenses, disbursements and
        advances incurred or made by the Trustee in accordance with this Agreement
        (including fees and expenses of its counsel and all persons not regularly
        in its
        employment and any amounts described in Section 10.01 to which the Trustee
        is
        entitled as provided therein), except any such expenses, disbursements and
        advances that either (i) arise from its negligence, bad faith or willful
        misconduct or (ii) do not constitute “unanticipated expenses” within the meaning
        of Treasury Regulations Section 1.860G-1(b)(3)(ii). Each Custodian shall
        receive
        compensation and reimbursement or payment of its expenses under the Custodial
        Agreement as provided therein; provided that, to the extent required under
        Section 6, Section 7 or Section 20 of the Custodial Agreement, the Trustee
        is
        hereby authorized to pay such compensation or reimbursement from amounts
        on
        deposit in the Certificate Account prior to any distributions to
        Certificateholders pursuant to Section 5.02 hereof.

       

      Section
        6.13. Collection
        of Monies.

       

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

       

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

       

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

       

      (i) Any
        failure by the Master Servicer to furnish to the Trustee the Mortgage Loan

        by
        the Trustee or to such Master Servicer and the Trustee by any NIMS Insurer
        or
        Holders of not less than 25% of the Class Principal Amount (or Class Notional
        Amount) of each Class of Certificates affected thereby; or

      

      
        
          
            
            

          

          
            126

            
              

            

          

          
            
            

          

        

      

      

       

      (ii) Any
        failure by the Master Servicer to duly perform, within the required time
        period

        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

        any
        material respect any other of the covenants or agreements on the part of
        such
        Master Servicer contained in this Agreement which continues unremedied for

        less than 25% of the Class Principal Amount (or Class Notional Amount) of
        each
        Class of Certificates affected thereby or by any NIMS Insurer; or

       

      (v) A
        decree
        or order of a court or agency or supervisory authority having jurisdiction
        for
        the appointment of a conservator or receiver or liquidator in any insolvency,
        readjustment of debt, marshalling of assets and liabilities or similar
        proceedings, or for the winding-up or liquidation of its affairs, shall have
        been entered against the Master Servicer, and such decree or order shall

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

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

      (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 60 days after the date on
        which
        written notice of such incorrect representation or warranty shall have been
        given to the Master Servicer by the Trustee or to the Master Servicer and
        the
        Trustee by the Holders of not less than 25% of the Aggregate Certificate
        Principal Amount of each Class of Certificates or by any NIMS Insurer;
        or

       

      (x) A
        sale or
        pledge of any of the rights of the Master Servicer hereunder or an assignment
        of
        this Agreement by the Master Servicer or a delegation of the rights or duties
        of
        the Master Servicer hereunder shall have occurred in any manner not otherwise
        permitted hereunder and without the prior written consent of the Trustee,
        any
        NIMS Insurer and Certificateholders holding more than 50% of the Class Principal
        Amount (or Class Notional Amount) of each Class of Certificates; or

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            128

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            129

            
              

            

          

          
            
            

          

        

      

      

       

      (b) On
        and
        after the time the Master Servicer (and the Trustee, if notice is sent by
        any
        NIMS Insurer) receives a notice of termination from the Trustee pursuant
        to
        Section 6.14(a) or the Trustee receives the resignation of the Master Servicer
        evidenced by an Opinion of Counsel pursuant to Section 9.28 and within 90
        days
        of such notice, the Trustee, unless another master servicer acceptable to
        the
        NIMS Insurer, such consent shall not be unreasonably withheld, shall have
        been
        appointed, shall be the successor in all respects to the Master Servicer
        in its
        capacity as such under this Agreement and the transactions set forth or provided
        for herein and shall have all the rights and powers and be subject to all
        the
        responsibilities, duties and liabilities relating thereto and arising thereafter
        placed on the Master Servicer hereunder, including the obligation to make
        Advances; provided, however, that any failure to perform such duties or
        responsibilities caused by the Master Servicer’s failure to provide information
        required by this Agreement shall not be considered a default by the Trustee
        hereunder. In addition, the Trustee shall have no responsibility for any
        act or
        omission of the Master Servicer prior to the issuance of any notice of
        termination. The Trustee shall have no liability relating to the representations
        and warranties of the Master Servicer set forth in Section 9.14. In the
        Trustee’s capacity as such successor, the Trustee shall have the same
        limitations on liability herein granted to the Master Servicer. As compensation
        therefor, the Trustee shall be entitled to receive all compensation payable
        to
        the Master Servicer under this Agreement, including the Master Servicing
        Fee and
        the compensation described in Section 9.21. The Trustee shall be entitled
        to be
        reimbursed from the Master Servicer (or by the Trust Fund if the Master Servicer
        is unable to fulfill its obligations hereunder) for all costs associated
        with
        the transfer of master servicing from the predecessor master servicer,
        including, without limitation, any costs or expenses associated with the
        complete transfer of all master servicing data and the completion, correction
        or
        manipulation of such master servicing data as may be required by the Trustee
        to
        correct any errors or insufficiencies in the master servicing data or otherwise
        to enable the Trustee to master service the Mortgage Loans properly and
        effectively.

       

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

      Section
        6.15. Additional
        Remedies of Trustee Upon Event of Default.

       

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

       

      Section
        6.16. Waiver
        of Defaults.

       

      35%
        or
        more of the Aggregate Voting Interests of Certificateholders (with the consent
        of any NIMS Insurer) may waive any default or Event of Default by the Master
        Servicer in the performance of its obligations hereunder, except that a default
        in the making of any required deposit to the Certificate Account that would
        result in a failure of the Trustee to make any required payment of principal
        of
        or interest on the Certificates may only be waived with the consent of 100%
        of
        the affected Certificateholders and with the consent of any NIMS Insurer.
        Upon
        any such waiver of a past default, such default shall cease to exist, and
        any
        Event of Default arising therefrom shall be deemed to have been remedied
        for
        every purpose of this Agreement. No such waiver shall extend to any subsequent
        or other default or impair any right consequent thereon except to the extent
        expressly so waived.

      Section
        6.17. Notification
        to Holders.

       

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

       

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

       

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

       

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

       

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

      (b) [Reserved].

       

      (c) The
        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 (g) of
        this Section 6.20 in respect of the Trust Fund as and to the extent required
        under the Exchange Act.

       

      (d) Reports
        Filed on Form 10-D. 

       

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

       

      (ii) As
        set
        forth on Exhibit P-1 hereto, within five calendar days after the related
        Distribution Date, (A) certain parties to the Structured Adjustable Rate
        Mortgage Loan Trust 2007-2 transaction, as identified on Exhibit P-1, shall
        provide to the Trustee and the Depositor, to the extent known by a Responsible
        Officer thereof, in EDGAR-compatible form (which may be Word or Excel documents
        easily convertible to EDGAR format), or in such other form as otherwise agreed
        upon by the Trustee and such party, the form and substance of any Additional
        Form 10-D Disclosure, if applicable, and include with such Additional Form
        10-D
        Disclosure, an Additional Disclosure Notification in the form attached hereto
        as
        Exhibit P-4, and (B) the Depositor will approve, as to form and substance,
        or
        disapprove, as the case may be, the inclusion of the Additional Form 10-D
        Disclosure on Form 10-D. The Sponsor will be responsible for any reasonable
        fees
        and expenses assessed or incurred by the Trustee in connection with including
        any Additional Form 10-D Disclosure on Form 10-D pursuant to this
        paragraph.

       

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

      (e) Reports

        to the
        90th
        calendar
        day after the end of each fiscal year of the Trust Fund or such earlier date
        as
        may be required by the Exchange Act (the “10-K Filing Deadline”) (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. Each such Form 10-K shall include the following items, in each case

        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

        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
        prepare any Additional Form 10-K Disclosure, except as set forth in the next
        paragraph.

      (ii) As
        set
        forth on Exhibit P-2 hereto, no later than March 15 of each year that the
        Trust
        Fund is subject to the Exchange Act reporting requirements, commencing in
        2008,
        (A) the parties to the Structured Adjustable Rate Mortgage Loan Trust 2007-2
        transaction (as identified on Exhibit P-2) shall provide to the Trustee and
        the
        Depositor, to the extent known by a Responsible Officer thereof, in
        EDGAR-compatible form (which may be Word or Excel documents easily convertible
        to EDGAR format), or in such other form as otherwise agreed upon by the Trustee
        and such party, the form and substance of any Additional Form 10-K Disclosure,
        if applicable and include with such Additional Form 10-K Disclosure, an
        Additional Disclosure Notification in the form attached hereto as Exhibit
        P-4,
        and (B) the Depositor will approve, as to form and substance, or disapprove,
        as
        the case may be, the inclusion of the Additional Form 10-K Disclosure on
        Form
        10-K. The Trustee has no duty under this Agreement to monitor or enforce
        the
        performance by the parties listed on Exhibit P-2 of their duties under this
        paragraph or proactively solicit or procure from such parties any Form 10-K
        Disclosure Information. The Sponsor will be responsible for any reasonable
        fees
        and expenses assessed or incurred by the Trustee in connection with including
        any Additional Form 10-K Disclosure on Form 10-K pursuant to this paragraph.
        

       

      (iii) After
        preparing the Form 10-K, the Trustee shall forward electronically a draft
        copy
        of the Form 10-K to the Exchange Act Signing Party for review and approval.
        If
        the Master Servicer is the Exchange Act Signing Party and the Form 10-K includes
        Additional Form 10-K Disclosure, then the Form 10-K shall also be electronically
        distributed to the Depositor for review and approval. No later than the close
        of
        business New York City time on the 4th Business Day prior to the 10-K Filing
        Deadline, a senior officer of the Exchange Act Signing Party shall sign the
        Form
        10-K and return an electronic or fax copy of such signed Form 10-K (with
        an
        original executed hard copy to follow by overnight mail) to the Trustee.
        If a
        Form 10-K cannot be filed on time or if a previously filed Form 10-K needs
        to be
        amended, the Trustee will follow the procedures set forth in subsection (g)(ii)
        of this Section 6.20. Promptly (but no later than one Business Day) after

        deadline for filing such report with the Commission, the Trustee will make
        available on its internet website a final executed copy of each Form 10-K
        filed
        by the Trustee. The parties to this Agreement acknowledge that the performance
        by the Trustee of its duties under this Section 6.20(e) related to the timely
        preparation and filing of Form 10-K is contingent upon such parties (and
        any
        Additional Servicer or Servicing Function Participant) strictly observing
        all
        applicable deadlines in the performance of their duties under this Section
        6.20(e), Section 9.25(a), Section 9.25(b) and Section 9.26. The Trustee shall
        have no liability for any loss, expense, damage, claim arising out of or
        with
        respect to any failure to properly prepare and/or timely file such Form 10-K,
        where such failure results from the Trustee’s inability or failure to obtain or
        receive, on a timely basis, any information from any other party hereto needed
        to prepare, arrange for execution or file such Form 10-K, not resulting from
        its
        own negligence, bad faith or willful misconduct.

      

      
        
          
            
            

          

          
            135

            
              

            

          

          
            
            

          

        

      

      

       

      (iv) Each
        Form
        10-K shall include the Sarbanes-Oxley Certification. The Trustee, the Paying
        Agent (if other than the Trustee) and, if the Depositor is the Exchange Act
        Signing Party, the Master Servicer, shall, and the Trustee, the Paying Agent
        and
        the Master Servicer (if applicable) shall cause any Servicing Function
        Participant engaged by it to, provide to the Person who signs the Sarbanes-Oxley
        Certification (the “Certifying Person”), by March 15 of each year in which the
        Trust Fund is subject to the reporting requirements of the Exchange Act,
        a
        certification (each, a “Back-Up Certification”), in the form attached hereto as
        Exhibit Q-1 or, in the case of (x) the Paying Agent (if other than the Trustee),
        such other form as agreed to between the Paying Agent and the Exchange Act
        Signing Party, and (y) the Trustee, the form attached hereto as Exhibit Q-2),
        upon which the Certifying Person, the entity for which the Certifying Person
        acts as an officer, and such entity’s officers, directors and Affiliates
        (collectively with the Certifying Person, “Certification Parties”) can
        reasonably rely. The senior officer of the Exchange Act Signing Party shall
        serve as the Certifying Person on behalf of the Trust Fund. In the event
        the
        Master Servicer, the Paying Agent, the Trustee or any Servicing Function
        Participant engaged by such parties is terminated or resigns pursuant to
        the
        terms of this Agreement, such party or Servicing Function Participant shall
        provide a Back-Up Certification to the Certifying Person pursuant to this
        Section 6.20(e)(iv) with respect to the period of time it was subject to
        this
        Agreement.

       

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

       

      (f) Each
        of
        Form 10-D and Form 10-K requires the registrant to indicate (by checking
“yes”
or “no”) that it “(1) has filed all reports required to be filed by Section 13
        or 15(d) of the Exchange Act during the preceding 12 months (or for such
        shorter
        period that the registrant was required to file such reports), and (2) has
        been
        subject to such filing requirements for the past 90 days.” The Depositor shall
        notify the Trustee in writing, no later than the fifth calendar day after
        the
        related Distribution Date with respect to the filing of a report on Form
        10- D
        and no later than March 15th with respect to the filing of a report on Form
        10-K, whether the Trustee should indicate “[Yes ____] or [No____]” on Form 10-D
        or Form 10-K, as applicable; provided, that if the Trustee does not receive
        such
        written notification from the Depositor, then the Trustee shall be entitled
        to
        affirmatively conclude that the Depositor (1) has filed all reports required
        to
        be filed by Section 13 or 15(d) of the Exchange Act during the preceding
        12
        months (or for such shorter period if applicable), and (2) has been subject
        to
        such filing requirements for the past 90 days. The Trustee shall be entitled
        to
        rely on such written notification or an affirmative indication in the absence
        of
        such notification in timely preparing, executing and/or filing any such report
        in accordance with this Section 6.20(f).

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

        to
        the extent known by a Responsible Officer thereof, in EDGAR-compatible form
        (which may be Word or Excel documents easily convertible to EDGAR format),

        such other form as otherwise agreed upon by the Trustee and such party, the
        form
        and substance of any Form 8-K Disclosure Information, if applicable, and
        include
        with such Form 8-K Disclosure Information, an Additional Disclosure Notification
        in the form attached hereto as Exhibit P-4 and (B) the Depositor will approve,
        as to form and substance, or disapprove, as the case may be, the inclusion
        of
        the Form 8-K Disclosure Information. The Trustee has no duty under this
        Agreement to monitor or enforce the performance by the parties listed on
        Exhibit
        P-3 of their duties under this paragraph or proactively solicit or procure
        from
        such parties any Form 8-K Disclosure Information. The Sponsor will be
        responsible for any reasonable fees and expenses assessed or incurred by
        the
        Trustee in connection with including any Form 8-K Disclosure Information
        on Form
        8-K pursuant to this paragraph. 

       

      (iii) After
        preparing the Form 8-K, the Trustee shall forward electronically, no later
        than
        Noon New York city time on the 3rd Business Day after the Reportable Event,
        a
        draft copy of the Form 8-K to the Exchange Act Signing Party for review and
        approval. If the Master Servicer is the Exchange Act Signing Party, then
        the
        Form 8-K shall also be electronically distributed to the Depositor for review
        and approval. No later than Noon New York City time on the 4th Business Day
        after the Reportable Event, a duly authorized 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 (h)(ii) of this Section 6.20. Promptly (but no later
        than
        one Business Day) after the deadline for filing such form with the Commission,
        the Trustee will make available on its internet website a final executed
        copy of
        each Form 8-K prepared and filed by it pursuant to this Section 6.20(g).
        The
        parties to this Agreement acknowledge that the performance by the Trustee
        of its
        duties under this Section 6.20(g) related to the timely preparation and filing
        of Form 8-K is contingent upon such parties strictly observing all applicable
        deadlines in the performance of their duties under this Section 6.20(g).
        The
        Trustee shall have no liability for any loss, expense, damage or claim arising
        out of or with respect to any failure to properly prepare and/or timely file
        such Form 8-K, where such failure results from the Trustee’s inability or
        failure to obtain or receive, on a timely basis, any information from any
        other
        party hereto needed to prepare, arrange for execution or file such Form 8-K,
        not
        resulting from its own negligence, bad faith or willful misconduct.

      (h) Delisting;
        Amendments; Late Filings.

       

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

       

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

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

       

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

       

      (k) Promptly,
        but no later than one Business day after filing with the Commission, the
        Trustee
        will make available on its internet website, a final executed copy of each
        periodic report filed on Form 8-K, Form 10-D or other applicable form, and
        each
        annual report on Form 10-K, together in each case with a copy of the acceptance
        confirmation receipt from EDGAR.

       

      Section
        6.21. Reporting
        Requirements of the Commission.

       

      Each
        of
        the parties hereto acknowledges and agrees that the purpose of Sections 6.01,
        6.20, 9.25 and 9.26 of this Agreement is to facilitate compliance by the
        Sponsor, the Master Servicer, the Trustee and the Depositor 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, convention or consensus among active participants in
        the
        asset-backed securities markets, advice of counsel, 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 Trustee
        or the
        Depositor for delivery of additional or different information as the Sponsor,
        the Master Servicer, the Trustee or the Depositor may determine in good faith
        is
        necessary to comply with the provisions of Regulation AB, provided that such
        information is available without unreasonable effort or expense and within
        such
        timeframe as may be reasonably requested.

      Section
        6.22. No
        Merger. 

       

      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. 

       

      The
        Trustee (including in its capacity as Paying Agent) 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 of any Subcontractor in violation of Section 6.01 or any failure
        by
        the Trustee to deliver when and as required, the information pursuant to
        Section
        6.01(m), the disclosure and certificates applicable to the Trustee pursuant
        to
        Section 6.20 or any assessment of compliance pursuant to Section 9.25(a).
        This
        indemnification shall survive the termination of this Agreement or the
        termination of the Trustee hereunder.

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

      

      
        
          
            
            

          

          
            140

            
              

            

          

          
            
            

          

        

      

      

       

      (b) On
        any
        Distribution Date occurring after the date on which (x) the total Scheduled
        Principal Balance of the Mortgage Loans in Pool 1 is less than 10% of the
        Scheduled Principal Balance of the Mortgage Loans in Pool 1 as of the Cut-off
        Date or (y) the total Scheduled Principal Balance of the Mortgage Loans in
        Pool
        2 is less than 10% of the Scheduled Principal Balance of the Mortgage Loans
        in
        Pool 2 as of the Cut-off Date, the Master Servicer, with the prior written
        consent of any NIMS Insurer and the Seller (which consent will not be
        unreasonably withheld), may, upon written direction to the Trustee, cause
        the
        Trustee to sell (or arrange for the sale of) the assets of (x) Pool 1 or
        (y)
        Pool 2 and thereby effect the retirement of the related Certificates. Upon
        the
        repurchase of such Mortgage Loans, the Master Servicer shall, upon written
        direction to the Trustee, cause each of the SWAP REMIC, REMIC I-1 and REMIC
        I-2
        (in the case of a sale of the assets described in clause (x) above) or REMIC
        II-1 (in the case of a sale of the assets described in clause (y) above)
        to
        adopt a plan of complete liquidation pursuant to Section 7.03 hereof to sell
        all
        of its property. The property of the applicable Pool shall be sold at a price
        (the “Repurchase Price”) equal to: (i) 100% of the unpaid principal balance of
        each Mortgage Loan in such Pool on the day of such purchase plus interest
        accrued thereon at the applicable Mortgage Rate with respect to any such
        Mortgage Loan to the Due Date in the Due Period immediately preceding such
        Distribution Date, (ii) the fair market value of any applicable REO Property
        and
        any other applicable property (reduced, in the case of REO Property, by (x)
        reasonably anticipated disposition costs and (y) any amount by which the
        fair
        market value as so reduced exceeds the outstanding principal balance of the
        related Mortgage Loan), such fair market value to be determined by an appraiser
        or appraisers appointed by the Master Servicer with the consent of the Trustee
        and any NIMS Insurer, (iii) any unreimbursed Servicing Advances with respect
        to
        each applicable Mortgage Loan and (iv) any Swap Termination Payment payable
        to
        the Swap Counterparty as a result of a termination pursuant to Section 7.01;
        provided, however, if there are any NIM Securities outstanding, the Master
        Servicer may only exercise its option after receiving the prior written consent
        of the holders of such NIM Securities and, if such consent is given, the
        Purchase Price shall also include an amount equal to the sum of (1) any accrued
        interest on the NIM Securities related to the Mortgage Loans, (2) the unpaid
        principal balance of any such NIM Securities and (3) any other reimbursable
        expenses owed by the issuer of the NIM Securities (the “NIM Redemption Amount”).
        If the Master Servicer fails to exercise such right, the NIMS Insurer will
        have
        the option to direct the Master Servicer to exercise such option so long
        as it
        is insuring the NIMS Securities or it is owed any amounts in connection with
        its
        guaranty of the NIM Securities. Following receipt of such notice from the
        NIMS
        Insurer, the Master Servicer shall advise the NIMS Insurer whether it will
        exercise the option under this Section 7.01(b) for its own account and using
        its
        own funds, or whether it will exercise such option in its own name but for
        the
        NIMS Insurer's account and utilizing the NIMS Insurer's funds. If the Master
        Servicer exercises such option for the NIMS Insurer's account, the NIMS Insurer
        will remit the Purchase Price to the Master Servicer one Business Day prior
        to
        the day the Master Servicer is required to remit the Purchase Price to the
        Trustee. Following its receipt from the NIMS Insurer of the entire Purchase
        Price and its subsequent remittance to the Trustee of the entire Purchase
        Price,
        the Master Servicer will convey to the NIMS Insurer all of the rights it
        receives from the Trustee with respect to the related Mortgage Loans as a
        result
        of such remittance. The Master Servicer and each Servicer (or the Trustee,
        if
        applicable) shall be reimbursed from the Repurchase Price for any Mortgage
        Loan
        or related REO Property for any Advances or Servicing Advances made with
        respect
        to the Mortgage Loans that are reimbursable to the Master Servicer under
        this
        Agreement or to each Servicer under the related Servicing Agreement (or to
        the
        Trustee hereunder), together with any accrued and unpaid compensation and
        any
        other amounts due to the Master Servicer and the Trustee hereunder or the
        Custodians or the Servicers under their respective Custodial or Servicing
        Agreements, provided that any such compensation or other amount to be paid
        to
        the Custodians and any such other amounts to be paid to the Servicers are
        “unanticipated expenses” within the meaning of Treasury Regulation Section
        1.860G-1(b)(3)(ii). The Trustee shall distribute the assets of the applicable
        Pool or Pools on the Distribution Date on which the repurchase occurred.
        If the
        NIMS Insurer directs the Master Servicer to exercise such right as described
        above, then (i) the Master Servicer shall cause each related REMIC to adopt
        a
        plan of complete liquidation as described above and (ii) the NIMS Insurer
        shall
        remit the Purchase Price in immediately available funds to the Master Servicer
        at least three Business Days prior to the applicable Distribution Date and,
        upon
        receipt of such funds from the NIMS Insurer, the Master Servicer shall promptly
        deposit such funds in the Collection Account. The NIMS Insurer shall be
        obligated to reimburse the Master Servicer and the Trustee for their reasonable
        out-of-pocket expenses incurred in connection with the purchase of the Mortgage
        Loans and REO Property related to the Mortgage Pool at the direction of the
        NIMS
        Insurer and shall indemnify and hold harmless the Master Servicer and the
        Trustee for any losses, liabilities or expenses resulting from any claims
        directly resulting from or relating to the Master Servicer’s or Trustee’s sale
        or purchase of the Pool Assets at the direction of the NIMS Insurer, except
        to
        the extent such losses, liabilities or expenses arise out of or result from
        the
        Master Servicer’s or Trustee’s, as the case may be, negligence, bad faith or
        willful misconduct. Notwithstanding anything herein to the contrary, only
        an
        amount not to exceed to the Purchase Price, reduced by the portion thereof
        consisting of any Swap Termination Payment (such portion, the “Swap Optional
        Termination Payment”), shall be made available for distribution to the
        Certificates. The Swap Optional Termination Payment shall be withdrawn by
        the
        Trustee from the Collection Account and remitted to the Supplemental Interest
        Trust for payment to the Swap Counterparty. The Swap Optional Termination
        Payment shall not be part of any REMIC and shall not be paid into any account

      Section
        7.02. Procedure
        Upon Termination of Trust Fund.

       

      (a) Notice
        of
        any termination of the Trust Fund (or the retirement of the Certificates
        related
        to Pool 1 or Pool 2, as applicable) pursuant to the provisions of Section
        7.01,
        specifying the Distribution Date upon which the final distribution shall
        be
        made, shall be given promptly by the Trustee by first class mail to the
        applicable Certificateholders and any NIMS Insurer mailed (x) no later than
        five
        Business Days after the Trustee has received notice from the Master Servicer
        of
        its intent to exercise its right to cause the termination of the Trust Fund
        pursuant to Section 7.01(b) (or the retirement of the Certificates related
        to
        Pool 1 or Pool 2, as applicable, to the extent the other such Mortgage Group
        is
        not terminated pursuant to such Section 7.01(b)) or (y) upon the final payment
        or other liquidation of the last Mortgage Loan or REO Property in the Trust
        Fund. Such notice shall specify (A) the Distribution Date upon which final
        distribution on the Certificates of all amounts required to be distributed
        to
        Certificateholders pursuant to Section 5.02 will be made upon presentation
        and
        surrender of the Certificates at the Corporate Trust Office, and (B) that
        the
        Record Date otherwise applicable to such Distribution Date is not applicable,
        distribution being made only upon presentation and surrender of the Certificates
        at the office or agency of the Trustee therein specified. The Trustee shall
        give
        such notice to the Master Servicer, the Depositor, the Swap Counterparty
        and the
        Certificate Registrar at the time such notice is given to Holders of the
        Certificates. The Master Servicer shall give notice to the Swap Counterparty
        on
        the date the Master Servicer elects its option pursuant to Section 7.01(b).
        Upon
        any such termination of the entire Trust Fund, the duties of the Certificate
        Registrar with respect to the applicable Certificates shall terminate and
        the
        Trustee shall terminate, or request the Master Servicer to terminate, the
        Collection Account it maintains, and the Trustee shall terminate the Certificate
        Account and any other account or fund maintained with respect to the related
        Certificates, subject to the Trustee’s obligation hereunder to hold all amounts
        payable to Certificateholders in trust without interest pending such
        payment.

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

       

      (c) Any
        reasonable expenses incurred by the Trustee in connection with any termination
        or liquidation of the Trust Fund (or a Mortgage Pool thereof) shall be paid
        from
        proceeds received from the liquidation of the Trust Fund, but only to the
        extent
        that such expenses constitute “unanticipated expenses” within the meaning of
        Treasury Regulations Section 1.860G-1(b)(3)(ii).

       

      Section
        7.03. Additional
        Requirements under the REMIC Provisions.

       

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

       

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

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

       

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

       

      (B) The
        Trustee shall attach a statement to the final Federal income tax return for
        each
        of the SWAP REMIC, REMIC I-1 and REMIC I-2 stating that pursuant to Treasury
        Regulation § 1.860F-1, the first day of the 90-day liquidation period for each
        such REMIC was the date on which the Trustee sold such assets; and

       

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

       

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

       

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

       

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

       

      Section
        7.04. Optional
        Purchase Right of NIMS Insurer.

       

      The
        NIMS

        Section
          8.01. Limitation
          on Rights of Holders.

         

      

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

       

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

       

      Section
        8.02. Access
        to List of Holders.

       

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

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

       

      (c) Every
        Holder or Certificate Owner, if the Holder is a Clearing Agency, by receiving
        and holding a Certificate, agrees with the Depositor, the Trustee, the Master
        Servicer, the Certificate Registrar and the Trustee that neither the Depositor,
        the Trustee, 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, the Certificate Registrar, the
        Paying
        Agent and, where expressly required herein, to the Master Servicer. Such
        instrument or instruments (as the action embodies therein and evidenced thereby)
        are herein sometimes referred to as an “Act” of the Holders signing such
        instrument or instruments. Proof of execution of any such instrument or of
        a
        writing appointing any such agents shall be sufficient for any purpose of
        this
        Agreement and conclusive in favor of the Trustee, the Trustee and Master
        Servicer, if made in the manner provided in this Section. The Trustee and
        Master
        Servicer shall promptly notify the other of receipt of any such instrument
        by
        it, and shall promptly forward a copy of such instrument to the
        other.

       

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

      (c) The
        ownership of Certificates (whether or not such Certificates shall be overdue
        and
        notwithstanding any notation of ownership or other writing thereon made by
        anyone other than the Trustee) shall be proved by the Certificate Register,
        and
        none of the Trustee, the Paying Agent, 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 shall bind every future Holder of
        the
        same Certificate and the Holder of every Certificate issued upon the
        registration of transfer thereof or in exchange therefor or in lieu thereof,
        in
        respect of anything done, omitted or suffered to be done by the Trustee or
        the
        Master Servicer in reliance thereon, whether or not notation of such action
        is
        made upon such Certificate.

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

       

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

       

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

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

       

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

       

      Section
        9.04. Power
        to Act; Procedures.

       

      (a) The
        Master Servicer shall master service the Mortgage Loans and shall have full
        power and authority, subject to the REMIC Provisions and the provisions of
        Article X hereof, and each Servicer shall have full power and authority (to
        the
        extent provided in the applicable Servicing Agreement) to do any and all
        things
        that it may deem necessary or desirable in connection with the servicing
        and
        administration of the Mortgage Loans, including but not limited to the power
        and
        authority (i) to execute and deliver, on behalf of the Certificateholders
        and
        the Trustee, customary consents or waivers and other instruments and documents,
        (ii) to consent to transfers of any Mortgaged Property and assumptions of
        the
        Mortgage Notes and related Mortgages, (iii) to collect any Insurance Proceeds
        and Liquidation Proceeds, and (iv) to effectuate foreclosure or other conversion
        of the ownership of the Mortgaged Property securing any Mortgage Loan, in
        each
        case, in accordance with the provisions of this Agreement and the applicable
        Servicing Agreement, as applicable; provided that the Master Servicer shall
        not
        take, or knowingly permit any Servicer to take, any action that is inconsistent
        with or prejudices the interests of the Trust Fund or the Certificateholders
        in
        any Mortgage Loan or the rights and interests of the Depositor, the Trustee
        and
        the Certificateholders under this Agreement. The Master Servicer further
        is
        authorized and empowered by the Trustee, on behalf of the Certificateholders
        and
        the Trustee, in its own name or in the name of any Servicer (to the extent
        permitted in the applicable Servicing Agreement), when the Master Servicer
        or a
        Servicer, as the case may be, believes it is appropriate in its best judgment
        to
        register any Mortgage Loan with MERS, or cause the removal from the registration
        of any Mortgage Loan on the MERS system, to execute and deliver, on behalf
        of
        the Trustee and the Certificateholders or any of them, any and all instruments
        of assignment and other comparable instruments with respect to such assignment
        or re-recording of a Mortgage in the name of MERS, solely as nominee for
        the
        Trustee and its successors and assigns. The Master Servicer shall represent
        and
        protect the interests of the Trust Fund in the same manner as it protects
        its
        own interests in mortgage loans in its own portfolio in any claim, proceeding
        or
        litigation regarding a Mortgage Loan and shall not make or knowingly permit
        any
        Servicer to make any modification, waiver or amendment of any term of any
        Mortgage Loan that would cause any REMIC included in the Trust Fund to fail
        to
        qualify as a REMIC or result in the imposition of any tax under Section 860F(a)
        or Section 860G(d) of the Code. Without limiting the generality of the
        foregoing, the Master Servicer in its own name or in the name of a Servicer,
        and
        each Servicer, to the extent such authority is delegated to such Servicer
        by the
        Master Servicer under the applicable Servicing Agreement, is hereby authorized
        and empowered by the Trustee when the Master Servicer or a Servicer, as the
        case
        may be, believes it appropriate in its best judgment and in accordance with
        Accepted Servicing Practices and the applicable Servicing Agreement, to execute
        and deliver, on behalf of itself and the Certificateholders, the Trustee
        or any
        of them, any and all instruments of satisfaction or cancellation, or of partial
        or full release or discharge and all other comparable instruments, with respect
        to the Mortgage Loans and with respect to the Mortgaged Properties. The Trustee
        shall furnish the Master Servicer or a Servicer, upon request, with any powers
        of attorney prepared by the Master Servicer or such Servicer empowering the
        Master Servicer or such Servicer to execute and deliver instruments of
        satisfaction or cancellation, or of partial or full release or discharge,
        and to
        foreclose upon or otherwise liquidate Mortgaged Property, and to appeal,
        prosecute or defend in any court action relating to the Mortgage Loans or
        the
        Mortgaged Property, in accordance with the applicable Servicing Agreement
        and
        this Agreement, and the Trustee shall execute and deliver such other documents,
        as the Master Servicer may request, necessary or appropriate to enable the
        Master Servicer to master service the Mortgage Loans and carry out its duties
        hereunder and to allow each Servicer to service the Mortgage Loans, in each
        case
        in accordance with Accepted Servicing Practices (and the Trustee shall have
        no
        liability for misuse of any such powers of attorney by the Master Servicer
        or
        the applicable Servicer). If the Master Servicer or the Trustee has been
        advised
        that it is likely that the laws of the state in which action is to be taken
        prohibit such action if taken in the name of the Trustee or that the Trustee
        would be adversely affected under the “doing business” or tax laws of such state
        if such action is taken in its name, then upon request of the Trustee, the
        Master Servicer shall join with the Trustee in the appointment of a co-trustee
        pursuant to Section 6.09 hereof. In the performance of its duties hereunder,
        the
        Master Servicer shall be an independent contractor and shall not, except
        in
        those instances where it is taking action in the name of the Trustee, be
        deemed
        to be the agent of the Trustee. Notwithstanding anything to the contrary,
        the
        Master Servicer shall not without Trustee’s written consent: (i) initiate any
        action, suit or proceeding solely under the Trustee’s name without indicating
        the Master Servicer’s representative capacity or (ii) take any action with the
        intent to cause, and which actually does cause, the Trustee to be registered
        to
        do business in any state.

      

      
        
          
            
            

          

          
            148

            
              

            

          

          
            
            

          

        

      

      

       

      (b) In
        master
        servicing and administering the Mortgage Loans, the Master Servicer shall
        employ
        procedures and exercise the same care that it customarily employs and exercises
        in master servicing and administering loans for its own account, giving due
        consideration to Accepted Servicing Practices where such practices do not
        conflict with this Agreement. Consistent with the foregoing, the Master Servicer
        may, and may permit any Servicer to, in its discretion (i) waive any late
        payment charge (but not any Prepayment Penalty Amount, except as set forth
        below) and (ii) extend the due dates for payments due on a Mortgage Note
        for a
        period not greater than 120 days; provided, however, that the maturity of
        any
        Mortgage Loan shall not be extended past the date on which the final payment
        is
        due on the latest maturing Mortgage Loan as of the Cut-off Date. In the event
        of
        any extension described in clause (ii) above, the Master Servicer shall make
        or
        cause to be made Advances on the related Mortgage Loan in accordance with
        the
        provisions of Section 5.04 on the basis of the amortization schedule of such
        Mortgage Loan without modification thereof by reason of such extension.
        Notwithstanding anything to the contrary in this Agreement, the Master Servicer
        shall not make or knowingly permit any modification, waiver or amendment
        of any
        material term of any Mortgage Loan unless: (1) such Mortgage Loan is in default
        or default by the related Mortgagor is, in the reasonable judgment of the
        Master
        Servicer or the applicable Servicer, reasonably foreseeable, (2) in the case
        of
        a waiver of a Prepayment Penalty Amount if (a) such Mortgage Loan is in default
        or default by the related Mortgagor is reasonably foreseeable, and such waiver
        would maximize recovery of total proceeds taking into account the value of
        such
        Prepayment Penalty Amount and the related Mortgage Loan or (b) the prepayment
        is
        not the result of a refinance by the Servicer or any of its affiliates and
        (i)
        such Mortgage Loan is in default or default by the related Mortgagor is,
        in the
        reasonable judgment of the Master Servicer or the applicable Servicer,
        reasonably foreseeable, and such waiver would maximize recovery of total
        proceeds taking into account the value of such Prepayment Penalty Amount
        and the
        related Mortgage Loan or (ii) the collection of the Prepayment Penalty Amount
        would be in violation of applicable laws or (iii) the collection of such
        Prepayment Penalty Amount would be considered “predatory” pursuant to written
        guidance published or issued by any applicable federal, state or local
        regulatory authority acting in its official capacity and having jurisdiction
        over such matters, and (3) the Master Servicer shall have provided or caused
        to
        be provided to the Trustee an Opinion of Counsel (which opinion shall, if
        provided by the Master Servicer, be an expense reimbursed, to the extent
        it is
        an unanticipated expense within the meaning of Treasury Regulation Section
        1.860G-1(b)(3)(ii) from the Collection Account pursuant to Section 4.02(v))
        in
        writing to the effect that such modification, waiver or amendment would not
        cause an Adverse REMIC Event; provided, in no event shall an Opinion of Counsel
        be required for the waiver of a Prepayment Penalty Amount under clause (2)
        above.

      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, the Trustee or the Master Servicer.

       

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

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

       

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

       

      Section
        9.06. Collection
        of Taxes, Assessments and Similar Items.

       

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

      

      
        
          
            
            

          

          
            151

            
              

            

          

          
            
            

          

        

      

      

       

      (b) Costs
        incurred by the Master Servicer or by Servicers in effecting the timely payment
        of taxes and assessments on the properties subject to the Mortgage Loans
        may be
        added to the amount owing under the related Mortgage Note where the terms
        of the
        Mortgage Note so permit; provided, however, that the addition of any such
        cost
        shall not be taken into account for purposes of calculating the distributions
        to
        be made to Certificateholders. Such costs, to the extent that they are
        unanticipated expenses within the meaning of Treasury Regulations Section
        1.860G-1(b)(3)(ii) shall be recoverable by the Master Servicer pursuant to
        Section 4.02(v).

       

      Section
        9.07. Termination
        of Servicing Agreements; Successor Servicers.

       

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

       

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

       

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

       

      Section
        9.08. Master
        Servicer Liable for Enforcement.

       

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

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

       

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

       

      Section
        9.10. Assumption
        of Servicing Agreement by Trustee.

       

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

       

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

       

      Section
        9.11. “Due-on-Sale”
        Clauses; Assumption Agreements.

      
        

        
          
            
              
              

            

            
              153

              
                

              

            

            
              
              

            

          

        

        

      

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

       

       

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

       

      Section
        9.12. Release
        of Mortgage Files.

       

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

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

       

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

       

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

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

       

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

       

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

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

       

       

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

       

      (ii) the
        execution and delivery of this Agreement by the Master Servicer and its
        performance and compliance with the terms of this Agreement will not (A)
        violate
        the Master Servicer’s certificate of formation or limited liability company
        agreement, (B) violate any law or regulation or any administrative decree

        or
        result in the breach of, any material contract, agreement or other instrument
        to
        which the Master Servicer is a party or by which it is bound or to which
        any of
        its assets are subject, which violation, default or breach would materially
        and
        adversely affect the Master Servicer’s ability to perform its obligations under
        this Agreement;

       

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

       

      (iv) the
        Master Servicer is not in default with respect to any order or decree of
        any
        court or any order or regulation of any federal, state, municipal or

        adversely affect its performance hereunder;

       

      (v) the
        Master Servicer is not a party to or bound by any agreement or instrument
        or
        subject to any certificate of formation or limited liability company agreement
        provision or any other company restriction or any judgment, order, writ,
        injunction, decree, law or regulation that may materially and adversely affect
        its ability as Master Servicer to perform its obligations under this Agreement
        or that requires the consent of any third person to the execution of this
        Agreement or the performance by the Master Servicer of its obligations under
        this Agreement;

       

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

      
        

        
          
            
              
              

            

            
              157

              
                

              

            

            
              
              

            

          

        

        

      

      (vii) the
        Master Servicer, or an Affiliate thereof the primary business of which is
        the
        servicing of conventional residential mortgage loans, is an FNMA- and FHLMC-
        approved seller/servicer;

       

       

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

       

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

       

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

       

      (b) It
        is
        understood and agreed that the representations and warranties set forth in
        this
        Section 9.14 shall survive the execution and delivery of this Agreement.
        The
        Master Servicer shall indemnify the Depositor and the Trustee and hold them
        harmless against any loss, damages, penalties, fines, forfeitures, legal
        fees
        and related costs, judgments, and other costs and expenses arising out of
        or
        related to any claim, demand, defense or assertion based on or grounded upon,
        or
        resulting from, a breach of the Master Servicer’s representations and warranties
        contained in Section 9.14(a). Notwithstanding anything in this Agreement
        to the
        contrary, the Master Servicer shall not be liable for special, indirect or
        consequential losses or damages of any kind whatsoever (including, but not
        limited to, lost profits). It is understood and agreed that the enforcement
        of
        the obligation of the Master Servicer set forth in this Section to indemnify
        the
        Depositor and the Trustee as provided in this Section constitutes the sole
        remedy (other than as set forth in Section 6.14) of the Depositor and the
        Trustee, respecting a breach of the foregoing representations and warranties.
        Such indemnification shall survive any termination of the Master Servicer
        as
        Master Servicer hereunder, and any termination of this Agreement.

       

      Any
        cause
        of action against the Master Servicer relating to or arising out of the breach
        of any representations and warranties made in this Section shall accrue upon
        discovery of such breach by any of the Depositor, Master Servicer, any NIMS
        Insurer or the Trustee or notice thereof by any one of such parties to the
        other
        parties.

       

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

      
        

        
          
            
              
              

            

            
              158

              
                

              

            

            
              
              

            

          

        

        

      

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

       

       

      Section
        9.15. Closing
        Certificate and Opinion.

       

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

       

      Section
        9.16. Standard
        Hazard and Flood Insurance Policies.

       

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

       

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

       

      Section
        9.17. Presentment
        of Claims and Collection of Proceeds.

       

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

      Section
        9.18. Maintenance
        of the Primary Mortgage Insurance Policies.

       

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

       

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

       

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

       

      The
        Trustee (or the applicable Custodian, as directed by the Trustee), shall
        retain
        possession and custody of the originals of the Primary Mortgage Insurance
        Policies or certificate of insurance if applicable and any certificates of
        renewal as to the foregoing as may be issued from time to time as contemplated
        by this Agreement. Until all amounts distributable in respect of the
        Certificates have been distributed in full and the Master Servicer otherwise
        has
        fulfilled its obligations under this Agreement, the Trustee (or the applicable
        Custodian, 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), 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.

      
        

        
          
            
              
              

            

            
              160

              
                

              

            

            
              
              

            

          

        

        

      

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

       

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

       

      Section
        9.21. Compensation
        to the Master Servicer.

       

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

        Proceeds or other recoveries, to the extent permitted by Section 4.02. Servicing
        compensation in the form of assumption fees, if any, late payment charges,
        as

        Amount) shall be retained by the Master Servicer (or the applicable Servicer)
        and shall not be deposited in the Collection Account. If the Master Servicer
        does not retain or withdraw the Master Servicing Fee from the Collection
        Account
        as provided herein, the Master Servicer shall be entitled to direct the Paying
        Agent to pay the Master Servicing Fee to such Master Servicer by withdrawal
        from
        the Certificate Account to the extent that payments have been received with
        respect to the applicable Mortgage Loan. The Master Servicer shall be required
        to pay all expenses incurred by it in connection with its activities hereunder
        and shall not be entitled to reimbursement therefor except as provided in

        9.21
        are subject to the provisions of Section 6.14(b).

      Section
        9.22. REO
        Property.

       

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

       

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

       

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

       

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

      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 to
        the
        Master Servicer and the Depositor) at any time an affiliate of any of the
        parties listed on Exhibit R to this Agreement. On or before March 1st
        of each
        year, the Depositor shall distribute the information in Exhibit R to the
        Master
        Servicer.

       

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

       

      Section
        9.24. Reports
        to the Trustee.

       

      (a) Not
        later
        than 30 days after each Distribution Date, the Master Servicer shall forward
        to
        the Trustee and any NIMS Insurer a statement, deemed to have been certified

        Servicing Officer, setting forth the status of the Collection Account maintained
        by the Master Servicer as of the close of business on the related Distribution
        Date, indicating that all distributions required by this Agreement to be
        made by
        the Master Servicer have been made (or if any required distribution has not
        been
        made by the Master Servicer, specifying the nature and status thereof) and
        showing, for the period covered by such statement, the aggregate of deposits
        into and withdrawals from the Collection Account maintained by the Master
        Servicer. Copies of such statement shall be provided by the Master Servicer,
        upon request, to the Depositor, Attention: Contract Finance, and, upon request,
        any Certificateholders (or by the Trustee at the Master Servicer’s expense if
        the Master Servicer shall fail to provide such copies (unless (i) the Master
        Servicer shall have failed to provide the Trustee with such statement or
        (ii)
        the Trustee shall be unaware of the Master Servicer’s failure to provide such
        statement)).

      
        

        
          
            
              
              

            

            
              163

              
                

              

            

            
              
              

            

          

        

        

      

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

        in
        connection with similar transactions, “loan level” information with respect to
        the Mortgage Loans as of the related Determination Date, to the extent that
        such
        information has been provided to the Master Servicer by the Servicers or
        by the
        Depositor.

       

      (c) All
        information, reports and statements prepared by the Master Servicer under
        this
        Agreement shall be based on information supplied to the Master Servicer by
        the
        Servicers without independent verification thereof and the Master Servicer
        shall
        be entitled to rely on such information.

       

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

       

      Section
        9.25. Assessment
        of Compliance and Attestation Reports. 

       

      (a) Assessment
        of Compliance

       

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

      

      
        
          
            
            

          

          
            164

            
              

            

          

          
            
            

          

        

      

      

       

      (ii) When
        the
        Master Servicer, the Paying Agent (if other than the Trustee) and the Trustee
        (or any Servicing Function Participant engaged by it) submit their assessments
        to the Trustee and the Master Servicer, such parties will also at such time
        include the assessment (and attestation pursuant to subsection (b) of this
        Section 9.25) of each Servicing Function Participant engaged by it and shall
        indicate to the Trustee what Relevant Servicing Criteria will be addressed
        in
        any such reports prepared by any such Servicing Function
        Participant.

       

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

       

      (b) Attestation
        Reports

       

      (i) On
        or
        before March 15th of each calendar year in which the Depositor is required
        to
        file reports with respect to the Trust Fund in accordance with the Exchange
        Act
        and the rules and regulations of the Commission, beginning with March 15,
        2008,
        the Master Servicer, the Paying Agent (if other than the Trustee) and the
        Trustee, each at its own expense, shall cause, and each such party shall
        cause
        any Servicing Function Participant engaged by it to cause, each at its own
        expense, a registered public accounting firm (which may also render other
        services to the Master Servicer, Paying Agent or Trustee, as the case may
        be)
        that is a member of the American Institute of Certified Public Accountants
        to
        furnish a report to the Sponsor, the Depositor, the Master Servicer and the
        Trustee, as applicable, to the effect that (A) it has obtained a representation
        regarding certain matters from the management of such party, which includes
        an
        assertion that such party has complied with the Relevant Servicing Criteria,
        and
        (B) on the basis of an examination conducted by such firm in accordance with
        standards for attestation engagements issued or adopted by the PCAOB, it
        is
        expressing an opinion as to whether such party’s compliance with the Relevant
        Servicing Criteria was fairly stated in all material respects, or it cannot
        express an overall opinion regarding such party’s assessment of compliance with
        the Relevant Servicing Criteria. If the Trustee and the Paying Agent are
        the
        same party, the attestation report caused to be furnished by the Trustee
        shall
        also address the Relevant Servicing Criteria of the Paying Agent. In the
        event
        that an overall opinion cannot be expressed, such registered public accounting
        firm shall state in such report why it was unable to express such an opinion.
        Such report must be available for general use and not contain restricted
        use
        language.

      

      
        
          
            
            

          

          
            165

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      (c) The
        Trustee’s, the Paying Agent’s and the Master Servicer’s obligation to provide
        assessments of compliance and attestations under this Section 9.25 shall
        terminate upon the filing of a Form 15 suspension notice on behalf of the
        Trust
        Fund.

        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.

        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

        further act on the part of any of the parties hereto, anything herein to
        the
        contrary notwithstanding; provided, however, that the successor or resulting

        to
        the succession to the Master Servicer under this Agreement by any Person
        (i)
        into which the Master Servicer may be merged or consolidated, or (ii) which

        of
        such succession or appointment, of such succession or appointment and shall
        furnish to the Depositor in writing and in form and substance reasonably
        satisfactory to the Depositor, all information reasonably necessary for the
        Trustee to accurately and timely report, pursuant to Section 6.20, the event
        under Item 6.02 of Form 8-K pursuant to the Exchange Act (if such reports
        under
        the Exchange Act are required to be filed under the Exchange Act).

      Section
        9.28. Resignation
        of Master Servicer.

       

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

       

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

       

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

       

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

       

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

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

       

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

       

      (c) None
        of
        the Master Servicer, the Seller, any NIMS Insurer or the Depositor or any
        of the
        directors, officers, employees or agents of any of them shall be under any
        liability to the Trustee or the Certificateholders for any action taken or
        for
        refraining from the taking of any action in good faith pursuant to this
        Agreement, or for errors in judgment; provided, however, that this provision
        shall not protect the Master Servicer, the Seller, any NIMS Insurer or the
        Depositor or any such person against any liability that would otherwise be
        imposed by reason of willful misfeasance, bad faith or negligence in its
        performance of its duties or by reason of reckless disregard for its obligations
        and duties under this Agreement. The Master Servicer, the Seller, any NIMS
        Insurer and the Depositor and any director, officer, employee or agent of
        the
        Master Servicer shall be entitled to indemnification by the Trust Fund and
        will
        be held harmless against any loss, liability or expense incurred in connection
        with any legal action relating to this Agreement or the Certificates other
        than
        any loss, liability or expense incurred by reason of willful misfeasance,
        bad
        faith or negligence in the performance of his or its duties hereunder or
        by
        reason of reckless disregard of his or its obligations and duties hereunder.
        The
        Master Servicer, the Seller and the Depositor and any director, officer,
        employee or agent of any of them may rely in good faith on any document of
        any
        kind prima facie properly executed and submitted by any Person respecting
        any
        matters arising hereunder. The Master Servicer shall be under no obligation
        to
        appear in, prosecute or defend any legal action that is not incidental to
        its
        duties to master service the Mortgage Loans in accordance with this Agreement
        and that in its opinion may involve it in any expenses or liability; provided,
        however, that the Master Servicer may in its sole discretion undertake any
        such
        action that it may deem necessary or desirable in respect to this Agreement
        and
        the rights and duties of the parties hereto and the interests of the
        Certificateholders hereunder. In such event, the legal expenses and costs
        of
        such action and any liability resulting therefrom shall be expenses, costs
        and
        liabilities of the Trust Fund and the Master Servicer shall be entitled to
        be
        reimbursed therefor out of the Collection Account it maintains as provided
        by
        Section 4.02. Notwithstanding anything herein to the contrary, neither the
        Master Servicer nor the Trustee shall have any liability for the servicing
        of
        the Additional Collateral, including, without limitation, the perfection,
        continuation, partial release, release, termination, realization upon,
        substitution, foreclosure, sale, or any other matter with respect to the
        Additional Collateral, or the enforcement of the Additional Collateral Servicing
        Agreement.

        9.31. Indemnification;
        Third-Party Claims.

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

       

      Section
        9.32. Allocation
        to Related Mortgage Pool.

       

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

      REMIC
        ADMINISTRATION

       

      Section
        10.01. REMIC
        and Grantor Trust Administration.

       

      (a) REMIC
        elections for each REMIC created hereunder as set forth in the Preliminary
        Statement and this Section 10.01 shall be made on Forms 1066 or other
        appropriate federal tax or information return for the taxable year ending
        on the
        last day of the calendar year in which the Certificates are issued. For purposes
        of such elections, (i) each of the SWAP REMIC Regular Interests is hereby
        designated as a regular interest in the SWAP REMIC; (ii) each of the REMIC
        I-1
        Regular Interests is hereby designated as a regular interest in REMIC I-1;
        (iii)
        each of the REMIC I-2 Regular Interests is hereby designated as a regular
        interest in REMIC I-2 and (iv) each of the REMIC II-1 Regular Interests is
        hereby designated as a regular interest in REMIC II-1. The Class SW-R Interest
        is hereby designated as the sole residual interest in the SWAP REMIC. The
        Class
        LTI1-R Interest is hereby designated as the sole residual interest in REMIC
        I-1.
        The Residual I Interest is hereby designated as the sole residual interest
        in
        REMIC I-2. The Class LTII1-R Interest is hereby designated as the sole residual
        interest in REMIC II-1. The Class R-I Certificate evidences ownership of
        the
        Class SW-R Interest, the Class LTI1-R Interest and the Residual I Interest.
        The
        Class R-II Certificate evidences ownership of the Class LTII1-R Interest.
        The
        Class P-I and Class P-II Certificates shall be neither regular interests
        nor
        residual interests in any REMIC created hereunder. It is the intention of
        the
        parties hereto that the segregated pool of assets consisting of any collections
        of Prepayment Penalty Amounts (i) related to the Mortgage Loans in Pool
        1
        and (ii) related to the Mortgage Loans in Pool 2,
        each
        constitute a grantor trust for federal income tax purposes. The Trustee,
        by its
        execution and delivery hereof, acknowledges the assignment to it of the Grantor
        Trust Assets and declares that it holds and will hold such assets in trust
        for
        the exclusive use and benefit of all present and future Holders of the Class
        P-I
        (in the case of collections of Prepayment Penalty Amounts related to Pool
        1) and
        Class P-II (in the case of collections of Prepayment Penalty Amounts related
        to
        Pool 2) Certificates. The rights of Holders of the Class P-I and Class P-II
        Certificates to receive distributions from the proceeds of the Grantor Trust
        Assets, and all ownership interests of such Holders in and to such
        distributions, shall be as set forth in this Agreement. It
        is
        intended that the rights of the Class 2-AX Certificates to receive payments
        in
        respect of FPD Premiums shall be accounted for as property held separate
        and
        apart from the REMIC regular interest represented by such Certificates. This
        provision is intended to satisfy the requirements of Treasury Regulations
        Section 1.860G-2(i) for the treatment of property rights coupled with REMIC
        interests to be separately respected and shall be interpreted consistently
        with
        such regulation.

      

      
        
          
            
            

          

          
            169

            
              

            

          

          
            
            

          

        

      

      

       

      

       

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

       

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

       

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

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

       

      (f) The
        Trustee, the Master Servicer and the Holders of Certificates shall take any
        action, within their respective control and scope of their duties, or cause
        any
        REMIC hereunder to take any action necessary to create or maintain the status
        of
        such REMIC as a REMIC under the REMIC Provisions and shall assist each other
        as
        necessary to create or maintain such status. Neither the Trustee, the Master
        Servicer nor the Holder of any Residual Certificate shall take any action,
        cause
        any REMIC to take any action or fail to take (or fail to cause to be taken)
        any
        action within their respective control and scope of their duties, that, under
        the REMIC Provisions, if taken or not taken, as the case may be, could (i)
        endanger the status of any such REMIC as a REMIC or (ii) result in the
        imposition of a tax upon any such REMIC (including but not limited to the
        tax on
        prohibited transactions as defined in Code Section 860F(a)(2) and the tax on
        prohibited contributions set forth on Section 860G(d) of the Code) (either
        such
        event, an “Adverse REMIC Event”) unless the Trustee, the NIMS Insurer and the
        Master Servicer have received an Opinion of Counsel (at the expense of the
        party
        seeking to take such action) to the effect that the contemplated action will
        not
        endanger such status or result in the imposition of such a tax. In addition,
        prior to taking any action with respect to any such REMIC or the assets therein,
        or causing any such REMIC to take any action, which is not expressly permitted
        under the terms of this Agreement, any Holder of a Residual Certificate will
        consult with the Trustee, the NIMS Insurer, the Master Servicer, or their
        respective designees, in writing, with respect to whether such action could
        cause an Adverse REMIC Event to occur with respect to such REMIC, and no
        such
        Person shall take any such action or cause such REMIC to take any such action
        as
        to which the Trustee, the NIMS Insurer or the Master Servicer has advised
        it in
        writing that an Adverse REMIC Event could occur.

       

      (g) The
        Trustee shall prepare or cause to be prepared on behalf of the Trust Fund,
        based
        upon information calculated in accordance with this Agreement pursuant to
        instructions given by the Depositor, and further, the Trustee shall sign
        and
        shall file, federal tax returns (including but not limited to appropriate
        REMIC
        elections on Form 1066) and appropriate state income tax returns and such
        other
        returns as may be required by applicable law relating to the Trust Fund,
        and
        shall file any other documents to the extent required by applicable state
        tax
        law (to the extent such documents are in the Trustee’s possession). The Trustee
        shall forward copies to the Depositor of all such returns and Form 1099
        supplemental tax information and such other information within the control
        of
        the Trustee as the Depositor may reasonably request in writing, and shall
        distribute to each Certificateholder such forms and furnish such information
        within the control of the Trustee as are required by the Code and the REMIC
        Provisions to be furnished to them, and will prepare and distribute to
        Certificateholders Form 1099 (supplemental tax information) (or otherwise
        furnish information within the control of the Trustee) to the extent required
        by
        applicable law. The Master Servicer shall indemnify the Trustee for any
        liability of or assessment against the Trustee, arising out of or based on
        any
        error in any of such tax or information returns directly resulting from errors
        in the information provided by such Master Servicer.

      

      
        
          
            
            

          

          
            171

            
              

            

          

          
            
            

          

        

      

      

       

      (h) The
        Trustee shall prepare and file with the Internal Revenue Service (“IRS”), on
        behalf of each REMIC, an application on IRS Form SS-4. The Trustee, upon
        receipt
        from the IRS of the Notice of Taxpayer Identification Number Assigned for
        each
        REMIC, shall promptly forward copies of such notices to the Trustee, the
        Master
        Servicer and the Depositor. The Trustee will file an IRS Form 8811 for the
        REMICs created hereunder. The Trustee shall sign such forms referred to in
        this
        Section 10.01(h) as may be required under applicable law.

       

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

       

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

       

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

       

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

       

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

       

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

      

      
        
          
            
            

          

          
            172

            
              

            

          

          
            
            

          

        

      

      

       

      REMIC
        I-1
        shall consist of the SWAP REMIC Regular Interests. The REMIC I-1 Regular
        Interests shall be designated as the regular interests in REMIC I-1, and
        the
        Class LTI1-R Interest shall be designated as the sole class of residual interest
        in REMIC I-1. Each of the REMIC I-1 Regular Interests shall have the
        characteristics set forth in the Preliminary Statement.

       

      The
        assets of REMIC I-2 shall be the REMIC I-1 Regular Interests. The REMIC I-2
        Regular Interests shall be designated as the regular interests in REMIC I-2
        and
        the Residual I Interest shall be designated as the sole class of residual
        interest in REMIC I-2. For federal income tax purposes, the interest rate
        on
        each REMIC I-2 Regular Interest (other than the Uncertificated Class 1-X
        Interest and other than the Class LTI2-IO Interest) shall be subject to a
        cap
        equal to the REMIC Pass-Through Rate.

       

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

       

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

       

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

       

      (o) It
        is
        intended that the rights of each Class of Pool 1 Certificates to receive
        payments in respect of Excess Interest shall be treated as a right in interest
        rate cap contracts written by the holders of the Class X Certificates in
        favor
        of the holders of each Class of the Pool 1 Certificates and such shall be
        accounted for as property held separate and apart from the regular interests
        in
        REMIC I-2 held by the holders of the Pool 1 Certificates. This provision
        is
        intended to satisfy the requirements of Treasury Regulations Section 1.860G-2(i)
        for the treatment of property rights coupled with REMIC interests to be
        separately respected and shall be interpreted consistently with such regulation.
        On each Distribution Date, to the extent that any of the Pool 1 Certificates
        receive payments in respect of Excess Interest, such amounts, to the extent
        not
        derived from payments on the Pool 1 Interest Rate Cap Agreement or from payments
        on the Swap Agreement, will be treated as distributed by REMIC I-2 to the
        Class
        X Certificates in
        respect of the Uncertificated Class 1-X Interest pro
        rata
        and then
        paid to the relevant Class of Pool 1 Certificates pursuant to the related
        interest cap agreement. The Trustee is hereby directed to perform its duties
        and
        obligations in accordance with this Section 10.01(o).

      

      
        
          
            
            

          

          
            173

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      (p) The
        parties hereto intend that the Uncertificated Class 1-X Interest, the
        uncertificated Class LTI2-IO Interest, the Pool 1 Interest Rate Cap Agreement,
        the Swap Agreement, the Supplemental Interest Trust, the right to receive
        payments in respect of Class I Shortfalls from the holders of the Pool 1
        Certificates, the Pool 1 Basis Risk Reserve Fund, the obligation of the holders
        of the Class X Certificates to pay amounts of Excess Interest to the holders
        of
        the Pool 1 Certificates and the right to receive FPD Premiums shall be treated
        as a “grantor trust” under the Code, and the provisions hereof shall be
        interpreted consistently with this intention. In furtherance of such intention,
        the Trustee shall (i) furnish or cause to be furnished to the holders of
        the
        Class X Certificates information regarding their allocable share, if any,
        of the
        income with respect to such grantor trust, (ii) file or cause to be filed
        with
        the Internal Revenue Service Form 1041 (together with any necessary attachments)
        and such other forms as may be applicable and (iii) comply with such information
        reporting obligations with respect to payments from such grantor trust to
        the
        holders of Pool 1 Certificates and Class X Certificates as may be applicable
        under the Code. The Trustee is hereby directed to perform its duties and
        obligations in accordance with this Section 10.01(p).

       

      The
        parties intend that all amounts paid to the Swap Counterparty under the Swap
        Agreement shall be deemed for federal income tax purposes to be paid by the
        Class X Certificates first, out of funds deemed received in respect of the
        Class
        LTI2-IO Interest, second, out of funds deemed received in respect of the
        Uncertificated Class 1-X Interest and third, out of funds deemed received
        in
        respect of Class I Shortfalls described in Section 10.01(o), and the provisions
        hereof shall be interpreted consistently with this intention. 

      

      
        
          
            
            

          

          
            174

            
              

            

          

          
            
            

          

        

      

      

       

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

       

      (q) [Reserved.]

       

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

       

      (s) The
        Trustee shall treat the 1-X Component Account as an outside reserve fund
        within
        the meaning of Treasury Regulation 1.860G-2(h) that is owned by the Holder
        of
        the Class C Certificates and that is not an asset of any REMIC.

       

      (t) The
        SWAP REMIC:
        On each
        Distribution Date, the Trustee shall first pay or charge as an expense of
        the
        SWAP REMIC all expenses of the Trust Fund related to Pool 1 for such
        Distribution Date, other than any Net Swap Payment or Swap Termination Payment
        required to be made from the Trust Fund.

       

      On
        each
        Distribution Date the Trustee shall distribute the aggregate Interest Remittance
        Amount for Pool 1 (net of expenses described in the preceding paragraph)
        with
        respect to each of the SWAP REMIC Regular Interests based on the interest
        rates
        for such interests set forth in the Preliminary Statement hereto.

       

      On
        each
        Distribution Date, the Trustee shall distribute the aggregate Principal
        Remittance Amount for Pool 1 with respect to the SWAP REMIC Regular Interests,
        first to the Class SW-Z Interest until its principal balance is reduced to
        zero,
        and then sequentially, to the other SWAP REMIC Regular Interests in ascending
        order of their numerical class designation, and, with respect to each pair
        of
        classes having the same numerical designation, in equal amounts to each such
        class, until the principal balance of each such class is reduced to zero.
        All
        losses on the Mortgage Loans in Pool 1 shall be allocated among the SWAP
        REMIC
        Regular Interests in the same manner that principal distributions are allocated.
        Increases in principal amount as a result of Subsequent Recoveries with respect
        to the Mortgage Loans in Pool 1 shall be allocated among the SWAP REMIC Regular
        Interests in the reverse fashion from the manner in which losses are allocated.
        Any amounts remaining in the SWAP REMIC after the aforementioned distributions
        shall be distributed to the Class SW-R Interest.

       

      REMIC
        I-1:
        All
        payments received by REMIC I-1 with respect to the SWAP REMIC Regular Interests
        shall be paid to the REMIC I-1 Regular Interests until the principal balance
        of
        all such interests have been reduced to zero and any losses allocated to
        such
        interests have been reimbursed. Any excess amounts shall be distributed to
        the
        Class LTI1-R Interest. 

       

      On
        each
        Distribution Date,

      

      
        
          
            
            

          

          
            175

            
              

            

          

          
            
            

          

        

      

      

       

      (i) interest
        shortfalls with respect to the Mortgage Loans shall be allocated to the REMIC
        I-1 Regular Interests (other than the Class LTI1-IO Interest) pro
        rata
        based on
        interest otherwise accrued thereon;

       

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

       

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

       

      If
        on any
        Distribution Date there is an increase in the Certificate Principal Amount
        of
        any Pool 1 Certificate as a result of the proviso in the definition of
        Certificate Principal Amount, then there shall be a corresponding increase
        in
        the principal amount of the REMIC I-1 Regular Interests allocated as
        follows:

       

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

       

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

       

      (u) Notwithstanding
        the priority and sources of payments set forth in Article 5 hereof or otherwise,
        the Trustee shall account for all distributions with respect to a Class of
        Pool
        1 Certificates in amounts that differ from those payable pursuant to the
        regular
        interest in REMIC I-2 corresponding to such Class as amounts paid or received
        (as appropriate) pursuant to the interest rate cap contracts or notional
        principal contracts provided for in this Section. In no event shall any such
        amounts be treated as payments with respect to a “regular interest” in a REMIC
        within the meaning of Code Section 860G(a)(1).

       

      Section
        10.02. Prohibited
        Transactions and Activities.

       

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

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

       

      In
        the
        event that a REMIC fails to qualify as a REMIC, loses its status as a REMIC,
        or
        incurs federal, state or local taxes as a result of a prohibited transaction
        or
        prohibited contribution under the REMIC Provisions due to the negligent
        performance by the Trustee of its duties and obligations set forth herein,
        the
        Trustee shall indemnify the NIMS Insurer and the Holder of the related Residual
        Certificate against any and all losses, claims, damages, liabilities or expenses
        (“Losses”) resulting from such negligence; provided, however, that the Trustee
        shall not be liable for any such Losses attributable to the action or inaction
        of the Master Servicer, the NIMS Insurer, the Depositor, or the Holder of
        such
        Residual Certificate or any other party, as applicable, nor for any such
        Losses
        resulting from misinformation provided by the Master Servicer, the Holder
        of
        such Residual Certificate on which the Trustee has relied. The foregoing
        shall
        not be deemed to limit or restrict the rights and remedies of the Holder
        of such
        Residual Certificate now or hereafter existing at law or in equity.
        Notwithstanding the foregoing, however, in no event shall the Trustee have
        any
        liability pursuant to this Section 10.03 (1) for any action or omission that
        is
        taken in accordance with and in compliance with the express terms of, or
        which
        is expressly permitted by the terms of, this Agreement, (2) for any Losses
        other
        than arising out of a negligent performance by the Trustee of its duties
        and
        obligations set forth herein, and (3) for any special or consequential damages
        to Certificateholders (in addition to payment of principal and interest on
        the
        Certificates).

       

      Section
        10.04. REO
        Property.

       

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

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

      (a) This
        Agreement may be amended from time to time by the Depositor, the Master Servicer
        and the Trustee, with the consent of the NIMS Insurer, but without the consent
        of any Holders or the Swap Counterparty (except to the extent that the rights
        or
        obligations of (1) the Swap Counterparty hereunder or (2) the Swap Counterparty
        under the Swap Agreement (or the ability of the Trustee on behalf of the
        Supplemental Interest Trust) to perform fully and timely its obligations
        under
        the Swap Agreement are affected thereby, in which case the prior written
        consent
        of the Swap Counterparty is required), (i) to cure any ambiguity, (ii) to
        cause
        the provisions herein to conform to or be consistent with or in furtherance
        of
        the statements made with respect to the Certificates, the Trust Fund or this
        Agreement in any Offering Document; or to correct or supplement any provision
        herein which may be inconsistent with any other provisions herein or with
        the
        provisions of any Servicing Agreement, (iii) to make any other provisions
        with
        respect to matters or questions arising under this Agreement or (iv) to add,
        delete, or amend any provisions to the extent necessary or desirable to comply
        with any requirements imposed by the Code and the REMIC Provisions as evidenced
        by an Opinion of Counsel. No such amendment effected pursuant to the preceding
        sentence shall, as evidenced by an Opinion of Counsel, result in an Adverse
        REMIC Event, nor shall such amendment effected pursuant to clause (iii) of
        such
        sentence adversely affect in any material respect the interests of any Holder.
        Prior to entering into any amendment without the consent of Holders pursuant
        to
        this paragraph, the Trustee, the Swap Counterparty and the NIMS Insurer may
        require an Opinion of Counsel (at the expense of the party requesting such
        amendment) to the effect that such amendment is permitted under this Section.
        Any such amendment shall be deemed not to adversely affect in any material
        respect any Holder, if the Trustee and the NIMS Insurer receive written
        confirmation from each Rating Agency that such amendment will not cause such
        Rating Agency to reduce, qualify or withdraw the then current rating assigned
        to
        the Certificates (and any Opinion of Counsel requested by the Trustee in
        connection with any such amendment may rely expressly on such confirmation
        as
        the basis therefor).

       

      (b) This
        Agreement may also be amended from time to time by the Depositor, the Master
        Servicer, the NIMS Insurer and the Trustee, but without the consent of the
        Swap
        Counterparty (except to the extent that the rights or obligations of (1)
        the
        Swap Counterparty hereunder or (2) the Swap Counterparty under the Swap
        Agreement (or the ability of the Trustee on behalf of the Supplemental Interest
        Trust) to perform fully and timely its obligations under the Swap Agreement
        are
        affected thereby, in which case the prior written consent of the Swap
        Counterparty is required) with the consent of the Holders of not less than
        66
        2/3% of the Class Principal Amount (or Percentage Interest) of each Class
        of
        Certificates affected thereby for the purpose of adding any provisions to
        or
        changing in any manner or eliminating any of the provisions of this Agreement
        or
        of modifying in any manner the rights of the Holders; provided, however,
        that no
        such amendment shall be made unless the Trustee receives an Opinion of Counsel
        addressed to the Trustee and the NIMS Insurer, at the expense of the party
        requesting the change, that such change will not cause an Adverse REMIC Event;
        and provided further, that no such amendment may (i) reduce in any manner
        the
        amount of, or delay the timing of, payments received on Mortgage Loans which
        are
        required to be distributed on any Certificate, without the consent of the
        Holder
        of such Certificate or (ii) reduce the aforesaid percentages of Class Principal
        Amount (or Percentage Interest) of Certificates of each Class, the Holders
        of
        which are required to consent to any such amendment without the consent of
        the
        Holders of 100% of the Class Principal Amount (or Class Notional Amount or
        Percentage Interest) of each Class of Certificates affected thereby. For
        purposes of this paragraph, references to “Holder” or “Holders” shall be deemed
        to include, in the case of any Class of Book-Entry Certificates, the related
        Certificate Owners.

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

       

      (d) It
        shall
        not be necessary for the consent of Holders under this Section 11.03 to approve
        the particular form of any proposed amendment, but it shall be sufficient
        if
        such consent shall approve the substance thereof. The manner of obtaining
        such
        consents and of evidencing the authorization of the execution thereof by
        Holders
        shall be subject to such reasonable regulations as the Trustee may
        prescribe.

       

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

       

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

       

      Section
        11.04. Voting
        Rights.

       

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

       

      Section
        11.05. Provision
        of Information.

       

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

       

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

      THIS
        AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
        NEW
        YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL
        BE

      Section
        11.14. Transfer
        of Servicing.

       

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

       

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

       

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

       

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

       

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

       

      (v) Such
        successor servicer must execute and deliver to the Trustee and the Master
        Servicer an agreement, in form and substance reasonably satisfactory to the
        Trustee and the Master Servicer, that contains an assumption by such successor
        servicer of the due and punctual performance and observance of each covenant
        and
        condition to be performed and observed by the applicable Servicer under the
        applicable Servicing Agreement or, in the case of a transfer of servicing
        to a
        party that is already a Servicer pursuant to this Agreement, an agreement
        to add
        the related Mortgage Loans to the Servicing Agreement already in effect with
        such Servicer;

      

      
        
          
            
            

          

          
            183

            
              

            

          

          
            
            

          

        

      

      

       

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

       

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

       

      Section
        11.15. Conflicts.

       

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

        provisions of this Agreement.

          information contained in paragraph 6 thereof is not true, and has no reason
          to
          believe that the Transferee has the intention to impede the assessment
          or
          collection of any federal, state or local taxes legally required to be
          paid with
          respect to a Residual Certificate. In addition, the Transferor has conducted
          a
          reasonable investigation at the time of the transfer and found that the
          Transferee had historically paid its debts as they came due and found no
          significant evidence to indicate that the Transferee will not continue
          to pay

        Date

         

        Dear
          Sirs:

         

        In
          connection with our proposed purchase of $______________ principal amount
          of
          Structured Adjustable Rate Mortgage Loan Trust Mortgage Pass-Through
          Certificates, Series 2007-2 (the “Privately Offered Certificates”) of Structured
          Asset Securities Corporation (the “Depositor”) which are held in the form of
          Definitive Certificates, we confirm that:

         

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

         

        2. We
          understand that, in connection with any proposed resale of any Privately
          Offered
          Certificates to an Institutional Accredited Investor, we will be required
          to
          furnish to the Trustee, the Certificate Registrar and the Depositor a
          certification from such transferee in the form hereof to confirm that the
          proposed sale is being made pursuant to an exemption from, or in a transaction
          not subject to, the registration requirements of the Securities Act. We
          further
          understand that the Privately Offered Certificates purchased by us will
          bear a
          legend to the foregoing effect.

         

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

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

         

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

         

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

         

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

         

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

         

        Very
          truly yours,
