    This
      TRUST AGREEMENT dated as of February 1, 2007 (the “Agreement”),
      is
      between MORGAN STANLEY CAPITAL I INC., a Delaware corporation, as depositor
      (the
“Depositor”)
      and
      LASALLE BANK NATIONAL ASSOCIATION, a national banking association, as trustee
      (the “Trustee”)
      and
      acknowledged by MORGAN STANLEY MORTGAGE CAPITAL INC., a New York corporation,
      as
      seller (the “Seller”),
      for
      purposes of Section 2.05.

    


    WITNESSETH
      THAT

    


    In
      consideration of the mutual agreements herein contained, the parties hereto
      agree as follows:

    


    PRELIMINARY
      STATEMENT

    


    The
      Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee
      in return for the Certificates. As provided herein, the Trustee will make
      multiple elections to treat a segregated pool of assets subject to this
      Agreement for federal income tax purposes as the following two separate real
      estate mortgage investment conduits (each, a “REMIC”):
      the
      Subsidiary REMIC and the Master REMIC. The Subsidiary REMIC will consist of
      the
      Mortgage Loans. The Subsidiary REMIC will issue the uncertificated REMIC regular
      interests specified below (each, a “Subsidiary
      REMIC Regular Interest”).
      The
      Subsidiary REMIC Regular Interests will represent the “regular interests” in the
      Subsidiary REMIC and the Class SR Interest will represent the single Class
      of
“residual interest” in the Subsidiary REMIC. 

     

    
      The
        Trustee will hold the Subsidiary REMIC Regular Interest for the benefit of
        the
        Master REMIC. The Master REMIC will consist of the Subsidiary REMIC Regular
        Interests and will be evidenced by the Certificates (other than the Class
        R
        Certificates), which will constitute the regular interests in the Master
        REMIC
        (the “Regular
        Certificates”)
        and
        the Class MR Interest, which will represent the single Class of “residual
        interest” in the Master REMIC. The Class R Certificates will represent the
        beneficial ownership of each of the Class SR and Class MR Interests. The
        “latest
        possible maturity date”
for
        federal income tax purposes of all REMICs, and regular and residual interests
        created hereunder will be the Latest Possible Maturity Date.



    

    Subsidiary
      REMIC

    


    The
      Subsidiary REMIC Interests, each of which (except for the Class SR Interest)
      is
      hereby designated as a REMIC regular interest for federal income tax purposes,
      will have the principal balances, pass-through rates and Corresponding Master
      REMIC Certificates as set forth in the following table:

      of delivery to the Trustee of the Custodian’s certifications as required under
      the related Custodial Agreement, that a document is missing from, a Trustee
      Mortgage File, or discovery by the Trustee, the Depositor, the Seller or the
      related Originator of the breach by such Originator or Seller of any
      representation or warranty under the related Purchase Agreement, as modified
      by
      the Acknowledgement, in the case of the Originator, or under this Agreement,
      in
      the case of the Seller, in respect of any Mortgage Loan which materially
      adversely affects the value of that Mortgage Loan or the interest therein of
      the
      Certificateholders (a “Defective
      Mortgage Loan”)
      (each
      of the Depositor, the Seller and the related Originator hereby agreeing to
      give
      written notice thereof to the Trustee and the other of such parties), the
      Trustee, or the applicable Custodian, shall promptly notify the Depositor and
      the Seller or the related Originator, as applicable, in writing of such
      nonconforming or missing document or breach and request that the Seller or
      related Originator deliver such missing document or cure or cause the cure
      of
      such defect or breach within a period of time specified in the related Purchase
      Agreement, and if the Seller or related Originator, as applicable, does not
      deliver such missing document or cure such defect or breach in all material
      respects during such period, the Trustee, shall notify the Depositor of such
      and, in consultation with the Depositor, undertake commercially reasonable
      efforts to enforce the obligations of the related Originator under the related
      Purchase Agreement, as modified by the Acknowledgement, or the Seller under
      this
      Agreement, as applicable, and cause the related Originator or the Seller, as
      the
      case may be, to repurchase that Mortgage Loan from the Trust Fund at the
      Purchase Price on or prior to the Determination Date following the expiration
      of
      such specified period (subject to Section 2.05(d) below); provided,
      however,
      that,
      in connection with any such breach that could not reasonably have been cured
      within such specified period (unless permitted a greater period of time to
      cure
      under the related Purchase Agreement), subject to Section 2.05(d) below, if
      the
      related Originator or the Seller, as applicable, shall have commenced to cure
      such breach within such specified period, the related Originator or the Seller
      shall be permitted to proceed thereafter diligently and expeditiously to cure
      the same within such additional time as is reasonably necessary to cure such
      breach. To the extent that any costs and damages are incurred by the Trust
      Fund
      as a result of any violation of any applicable federal, state, or local
      predatory or abusive lending law arising from or in connection with the
      origination of any Mortgage Loan repurchased by the related Originator or the
      Seller, such costs and damages shall be included in the Purchase Price of such
      repurchased Mortgage Loan and shall be borne by the Seller. With respect to
      a
      breach of a representation or warranty of by the related Originator under the
      related Purchase Agreement, if that Originator fails to cure the breach or
      repurchase the affected Mortgage Loan within the time period required by such
      Purchase Agreement, the Seller hereby agrees to honor that Originator’s cure
      obligations. The Purchase Price for the repurchased Mortgage Loan shall be
      deposited in the related Distribution Account, and the Trustee shall cause
      the
      related Custodian to release to the related Originator or the Seller, as
      applicable, the related Trustee Mortgage File and shall execute and deliver
      such
      instruments of transfer or assignment, in each case without recourse,
      representation or warranties, as either party shall furnish to it and as shall
      be necessary to vest in such party any Mortgage Loan released pursuant hereto
      and the Trustee, and the related Custodian, shall have no further responsibility
      with regard to such Trustee Mortgage File (it being understood that the Trustee
      shall have no responsibility for determining the sufficiency of such assignment
      for its intended purpose). If pursuant to the foregoing provisions the related
      Originator or the Seller repurchases a Mortgage Loan that is a MERS Mortgage
      Loan, the Servicer shall cause MERS to designate on the MERS® System the related
      Originator or the Seller, as applicable, as the beneficial holder of such
      Mortgage Loan.

    In
      lieu
      of repurchasing any such Mortgage Loan as provided above, the Originator or
      the
      Seller may cause such Mortgage Loan to be removed from the Trust Fund (in which
      case it shall become a Deleted Mortgage Loan) and substitute one or more
      Replacement Mortgage Loans in the manner and subject to the limitations set
      forth in Section 2.05(c) below. It is understood and agreed that the
      obligations of the Originators and the Seller to cure or to repurchase (or
      to
      substitute for) any related Mortgage Loan as to which a document is missing,
      a
      material defect in a constituent document exists or as to which such a breach
      has occurred and is continuing shall constitute the sole remedy against the
      such
      party respecting such omission, defect or breach available to the Trustee on
      behalf of the Certificateholders.

    


    (c) Any
      substitution of Replacement Mortgage Loans for Deleted Mortgage Loans made
      pursuant to Section 2.05(b) above must be effected prior to the last
      Business Day that is within two years after the Closing Date. As to any Deleted
      Mortgage Loan for which the related Originator or the Seller substitutes a
      Replacement Mortgage Loan or Loans, such substitution shall be effected by
      delivering to the related Custodian, on behalf of the Trustee, for such
      Replacement Mortgage Loan or Loans, the Mortgage Note, the Mortgage, any related
      assignment thereof and the Acknowledgement to the Trustee, and such other
      documents and agreements, with all necessary endorsements thereon, together
      with
      an Officers’ Certificate stating that each such Replacement Mortgage Loan
      satisfies the definition thereof and specifying the Substitution Adjustment
      Amount (as described below), if any, in connection with such substitution.
      Monthly Payments due with respect to Replacement Mortgage Loans in the month
      of
      substitution shall not be included as part of the Trust Fund and shall be
      retained by the related Originator or the Seller, as applicable. For the month
      of substitution, distributions to the Certificateholders shall reflect the
      collections and recoveries in respect of such Deleted Mortgage in the Due Period
      preceding the month of substitution and the related Originator or the Seller,
      as
      applicable, shall thereafter be entitled to retain all amounts subsequently
      received in respect of such Deleted Mortgage Loan. Upon such substitution,
      such
      Replacement Mortgage Loan shall constitute part of the Trust Fund and shall
      be
      subject in all respects to the terms of this Agreement and the related Purchase
      Agreement, as modified by the related Acknowledgement, including all
      representations and warranties thereof included in such Purchase Agreement,
      as
      modified by the Acknowledgement, in each case as of the date of
      substitution.

    For
      any
      month in which an Originator or the Seller substitutes one or more Replacement
      Mortgage Loans for one or more Deleted Mortgage Loans, the Servicer shall
      determine the excess (each, a “Substitution
      Adjustment Amount”),
      if
      any, by which the aggregate Purchase Price of all such Deleted Mortgage Loans
      exceeds the aggregate Stated Principal Balance of the Replacement Mortgage
      Loans
      replacing such Deleted Mortgage Loans, together with one month’s interest on
      such excess amount at the applicable Net Mortgage Rate. On the date of such
      substitution, the related Originator or Seller, as applicable, shall deliver
      or
      cause to be delivered to the Servicer for deposit in the related Custodial
      Account an amount equal to the related Substitution Adjustment Amount, if any,
      and the related Custodian, on behalf of the Trustee, upon receipt of the related
      Replacement Mortgage Loan or Loans and certification by the Servicer of such
      deposit, shall release to the related Originator or the Seller, as applicable,
      the related Trustee Mortgage File or Files and shall execute and deliver such
      instruments of transfer or assignment, in each case without recourse, as the
      related Originator or Seller shall deliver to it and as shall be necessary
      to
      vest therein any Deleted Mortgage Loan released pursuant hereto.

    


    In
      addition, the related Originator or the Seller, as applicable, shall obtain
      at
      its own expense and deliver to the Trustee an Opinion of Counsel to the effect
      that such substitution (either specifically or as a class of transactions)
      shall
      not cause an Adverse REMIC Event. If such Opinion of Counsel cannot be
      delivered, then such substitution may only be effected at such time as the
      required Opinion of Counsel can be given.

     

    
      (d) Upon
        discovery by the related Originator, the Seller, the Depositor or the Trustee
        that any Mortgage Loan does not constitute a “qualified mortgage” within the
        meaning of Section 860G(a)(3) of the Code, the party discovering such fact
        shall within two Business Days give written notice thereof to the other parties.
        In connection therewith, the applicable Originator or the Seller shall
        repurchase or, subject to the limitations set forth in Section 2.05(c),
        substitute one or more Replacement Mortgage Loans for the affected Mortgage
        Loan
        within 90 days of the earlier of discovery or receipt of such notice with
        respect to such affected Mortgage Loan. Any such repurchase or substitution
        shall be made in the same manner as set forth in Section 2.05(c) above
        and/or in accordance with this Section 2.05(d). The Trustee shall re-convey
        to
        the related Originator or the Seller, as applicable, the Mortgage Loan to
        be
        released pursuant hereto in the same manner, and on the same terms and
        conditions, as it would a Mortgage Loan repurchased for breach of a
        representation or warranty.

              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 in all
      of
      the Depositor’s right, title and interest in, to and under, whether now owned or
      hereafter acquired, the Trust Fund and all proceeds of any and all property
      constituting the Trust Fund to secure payment of the Certificates; and
      (3) this Agreement shall constitute a security agreement under applicable
      law. If such conveyance is deemed to be in respect of a loan and the trust
      created by this Agreement terminates prior to the satisfaction of the claims
      of
      any Person holding any Certificate, the security interest created hereby shall
      continue in full force and effect and the Trustee shall be deemed to be the
      collateral agent for the benefit of such Person, and all proceeds shall be
      distributed as herein provided.

    


    (b) The
      Depositor shall, to the extent consistent with this Agreement, take such
      reasonable actions as may be necessary to ensure that, if this Agreement were
      deemed to create a security interest in the Mortgage Loans and the other
      property described above, such security interest would be deemed to be a
      perfected security interest of first priority under applicable law and will
      be
      maintained as such throughout the term of this Agreement. The Depositor will,
      at
      its own expense, make all initial filings on or about the Closing Date and
      shall
      forward a copy of such filing or filings to the Trustee. Without limiting the
      generality of the foregoing, the Depositor shall prepare and forward for filing,
      or shall cause to be forwarded for filing, at the expense of the Depositor,
      all
      filings necessary to maintain the effectiveness of any original filings
      necessary under the relevant UCC to perfect the Trustee’s security interest in
      or lien on the Mortgage Loans, including without limitation
      (x) continuation statements, and (y) such other statements as may be
      occasioned by (1) any change of name of an Originator, the Depositor or the
      Trustee, (2) any change of location of the place of business or the chief
      executive office of the Seller or the Depositor, (3) any transfer of any
      interest of an Originator or the Depositor in any Mortgage Loan or (4) any
      change under the relevant UCC or other applicable laws. Neither the Originators
      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,
      any Originator 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 Originators and the Depositor authorizes its
      immediate or intermediate transferee (but not the Trustee) 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).

    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 Balance, or
      in
      the Percentage Interests, specified herein. Each Class of Certificates will
      be
      issued in the minimum denominations and integral multiples thereof of the
      initial Certificate Balance specified in the Preliminary Statement hereto.
      

    


    (b) The
      Certificates shall be executed by manual or facsimile signature on behalf of
      the
      Trustee by an authorized officer of the Trustee. 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 Trustee Mortgage Files
      described in Section 2.01. No Certificate shall be entitled to any benefit
      under this Agreement, or be valid for any purpose, unless there appears on
      such
      Certificate a certificate of authentication substantially in the form provided
      for herein, executed by an authorized officer of the Authenticating Agent,
      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 or on behalf of the Trustee to the Authenticating Agent for authentication
      and the Authenticating Agent shall authenticate and deliver such Certificates
      as
      in this Agreement provided and not otherwise.

    


    (c) The
      Class
      OC, Class  B-4, Class B-5, Class P and Class R Certificates offered
      and sold in reliance on the exemption from registration under Rule 144A
      under the Securities Act shall be issued initially 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”).

                3.02

            	
              Registration.
                

            


    

    


    The
      Trustee is hereby appointed, and the Trustee hereby accepts its appointment
      as,
      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 successor 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, 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.

              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 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 Balance 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 Balance 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 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, whether upon original issuance or
      subsequent transfer, each Holder of such a Certificate acknowledges the
      restrictions on the transfer of such Certificate set forth thereon and agrees
      that it will transfer such a Certificate only as provided herein.

    


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

    



    
      
        
        

      

      
        49

        
          

        

      

      
        
        

      

    


    (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 1933 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 Certificate Registrar with a certificate in the form of
      Exhibit H 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 Certificate Registrar a letter of the transferee
      substantially in the form of Exhibit I hereto.

    


    (d) No
      transfer of an ERISA-Restricted Certificate in the form of a Definitive
      Certificate shall be made to any Person or shall be effective unless the
      Certificate Registrar, on behalf of the Trustee, has received (A) a
      certificate substantially in the form of Exhibit J hereto (or
      Exhibit B, in the case of a Residual Certificate) from such transferee or
      (B) an Opinion of Counsel satisfactory to the Certificate Registrar and the
      Trustee to the effect that the purchase and holding of such a Certificate will
      not constitute or result in any nonexempt prohibited transactions under
      Title I of ERISA or Section 4975 of the Code and will not subject the
      Certificate Registrar, the Trustee or the Depositor to any obligation in
      addition to those undertaken in the Agreement; provided,
      however,
      that
      the Certificate Registrar 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 Certificate Registrar 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 and will not subject the Certificate Registrar,
      the Trustee or the Depositor to any obligation in addition to those undertaken
      in this Agreement. Each Transferee of an ERISA-Restricted Certificate that
      is a
      Book-Entry Certificate shall be deemed to have made the appropriate
      representation set forth in paragraph 2 and the representation set forth in
      paragraph 3 of Exhibit J. The preparation and delivery of the certificate
      and opinions referred to above shall not be an expense of the Trust Fund, the
      Certificate Registrar, the Trustee or the Depositor.

    


    Notwithstanding
      the foregoing, no opinion or certificate shall be required for the initial
      issuance of the ERISA-Restricted Certificates to the Underwriter. The
      Certificate Registrar 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 Certificate Registrar 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) and neither the Trustee
      nor the Paying Agent shall 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 shall be entitled, but not obligated, to recover
      from
      any Holder of any ERISA-Restricted Certificate that was in fact a Plan or a
      Person acting on behalf of a Plan any payments made on such ERISA-Restricted
      Certificate at and after such time. Any such payments so recovered by the
      Trustee shall be paid and delivered by the Trustee to the last preceding Holder
      of such Certificate that is not such a Plan or Person acting on behalf of a
      Plan.

    (e) As
      a
      condition of the registration of transfer or exchange of any Certificate, the
      Certificate Registrar may require the certified taxpayer identification number
      of the owner of the Certificate and the payment of a sum sufficient to cover
      any
      tax or other governmental charge imposed in connection therewith; provided,
      however,
      that
      the Certificate Registrar shall have no obligation to require such payment
      or to
      determine whether or not any such tax or charge may be applicable. No service
      charge shall be made to the Certificateholder for any registration, transfer
      or
      exchange of 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 (A) is 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 Certificate Registrar 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 Certificate Registrar an affidavit in substantially the form attached hereto
      as Exhibit B 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 and the Certificate
      Registrar an affidavit in substantially the form attached hereto as
      Exhibit C. In addition, the Trustee or the Certificate Registrar may (but
      shall have no obligation to) require, prior to and as a condition of any such
      transfer, the delivery by the proposed transferee of an Opinion of Counsel,
      addressed to the Trustee and the Certificate Registrar, 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 Depositor and the
      Certificate Registrar shall be under no 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 Trustee or the Paying Agent making any payments due on such Residual
      Certificate to the Holder thereof or for taking any other action with respect
      to
      such Holder under the provisions of the Agreement, so long as the transfer
      was
      effected in accordance with this Section 3.03(f), unless the 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, or an agent or nominee thereof, or Non-permitted Foreign Holder.
      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 Certificate Registrar
      shall be paid and delivered to the last preceding Holder of such Residual
      Certificate.

    If
      any
      purported transferee shall become a registered Holder of a Residual Certificate
      in violation of the provisions of this Section 3.03(f), then upon receipt
      of written notice to the Trustee or the Certificate Registrar that the
      registration of transfer of such Residual Certificate was not in fact permitted
      by this Section 3.03(f), the last preceding Permitted Transferee shall be
      restored to all rights as Holder thereof retroactive to the date of such
      registration of transfer of such Residual Certificate. The Depositor, the
      Certificate Registrar and 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), or for the Trustee or the Paying Agent
      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.

    


    Neither
      the Certified Registrar nor the Trustee will have any responsibility for any
      aspect of the records relating to or payments made on account of beneficial
      ownership interests of the Book-Entry Certificates or for maintaining,
      supervising or reviewing any records relating to such beneficial ownership
      interests or transfers thereof.

                of Certificates. 

            


    

    


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

                of Certificates. 

            


    

    


    If
      (i) any Certificate is mutilated and is surrendered to the Trustee or the
      Certificate Registrar or (ii) the Certificate Registrar receives evidence
      to its satisfaction of the destruction, loss or theft of any Certificate, and
      there is delivered to the Trustee and the Certificate Registrar 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, the Trustee or the Certificate Registrar
      that such destroyed, lost or stolen Certificate has been acquired by a protected
      purchaser, the Trustee shall execute and 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 Balance. Upon the issuance of any new Certificate under this
      Section 3.05, the Trustee, the Depositor or the Certificate Registrar 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, the Depositor or the Certificate
      Registrar) 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.

    If
      after
      the delivery of such new Certificate, a protected purchaser of the original
      Certificate in lieu of which such new Certificate was issued presents for
      payment such original Certificate, the Depositor, the Certificate Registrar
      and
      the Trustee or any agent shall be entitled to recover such new Certificate
      from
      the Person to whom it was delivered or any Person taking therefrom, except
      a
      protected purchaser, and shall be entitled to recover upon the security or
      indemnity provided therefor to the extent of any loss, damage, cost or expenses
      incurred by the Depositor, the Certificate Registrar, the Trustee or any agent
      in connection therewith.

      the Depositor, the Trustee, the Certificate Registrar, the Paying Agent and
      any
      agent of any of them shall 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 Trustee, the Certificate Registrar, the Paying Agent nor

                Certificates. 

            


    

    


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

    


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

              Appointment
                of Paying Agent. 

            


    

    


    The
      Trustee may appoint a Paying Agent (which may be the Trustee) for the purpose
      of
      making distributions to the Certificateholders hereunder. The Trustee is hereby
      appointed as the initial Paying Agent. The Trustee shall cause any Paying Agent,
      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 the Certificateholders in an
      Eligible Account (which shall be the Distribution 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 the
      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.

                Certificates. 

            


    

    


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

    


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

    


    (ii) the
      Certificate Registrar, the Paying Agent and the Trustee shall 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
      (A) the Clearing Agency or 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 satisfactory to
      the Depositor and the Certificate Registrar, the Certificate Registrar 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 Certificate Registrar of the Book-Entry Certificates
      by the Clearing Agency, accompanied by registration instructions from the
      Clearing Agency for registration, the Certificate Registrar shall issue the
      Definitive Certificates. Neither the Depositor, the Certificate Registrar 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 Certificate Registrar, to the
      extent applicable, with respect to such Definitive Certificates and the
      Certificate Registrar shall recognize the holders of the Definitive Certificates
      as Certificateholders hereunder. Notwithstanding the foregoing, the Certificate
      Registrar, upon the instruction of the Depositor, shall have the right to issue
      Definitive Certificates on the Closing Date in connection with credit
      enhancement programs.

      this Agreement, any Purchase Agreement, the Servicing Agreement or the related
      Custodial Agreement.

    


    (e) Funds
      in
      the Distribution Account may be invested in Permitted Investments selected
      by
      and at the written direction of the Trustee, which shall mature not later than
      one Business Day prior to the Distribution Date (except that if such Permitted
      Investment is an obligation of the Trustee or any of its Affiliates, or is
      managed or advised by the Trustee or any Affiliate, then such Permitted
      Investment shall mature not later than such applicable Distribution Date) and
      any such Permitted Investment shall not be sold or disposed of prior to its
      maturity. All such Permitted Investments shall be made in the name of the
      Trustee (in its capacity as such) or its nominee. All income and gain realized
      from any Permitted Investment of amounts on deposit in the Distribution Account
      shall be for the benefit of the Trustee, as additional compensation for its
      duties hereunder, and shall be subject to its withdrawal or order from time
      to
      time, and shall not be part of the Trust Fund; provided,
      however,
      that if
      LaSalle Bank National Association is no longer the Trustee, any such income
      and
      gain shall be paid to the successor Trustee. The amount of any losses incurred
      in respect of any such investments shall be deposited in such Distribution
      Account by the Trustee out of its own funds, without any right of reimbursement
      therefor, immediately as realized. At the Trustee’s discretion, funds in the
      Distribution Account may remain uninvested.

    The
      Trustee shall withdraw funds from the Distribution Account for distributions
      to
      Certificateholders in the manner specified in this Agreement (and to withhold
      from the amounts so withdrawn, the amount of any taxes that it is authorized
      to
      withhold pursuant to Section 9.01). In addition, the Trustee may from time
      to
      time make withdrawals from the Distribution Account for the following
      purposes:

    


    (i) to
      pay
      all amounts described in the sixth bullet of clause (1) of the definition of
      “Available Distribution Amount”;

    (ii) to
      withdraw and retain the investment earnings on the Distribution Account as
      its
      compensation for the related Distribution Date;

    


    (iii) to
      withdraw and return to the Servicer any amount deposited in the Distribution
      Account and not required to be deposited therein; and

    


    (iv) to
      clear
      and terminate the Distribution Account upon termination of the Agreement
      pursuant to Section 7.01.

                of Servicer’s Obligations.

            


    

    


    (a) Upon
      the
      occurrence of a default under the Servicing Agreement of which a Responsible
      Officer of the Trustee has actual knowledge, the Trustee, so long as any such
      default shall be continuing, may, and shall if it determines such action to
      be
      in the best interests of Certificateholders, (i) terminate all of the
      rights and powers of the Servicer pursuant to the applicable provisions of
      the
      Servicing Agreement; (ii) exercise any rights it may have to enforce the
      Servicing Agreement against the Servicer; and/or (iii) waive any such
      default under the Servicing Agreement or take any other action with respect
      to
      such default as is permitted thereunder; provided,
      however,
      that
      the Trustee shall not waive any default by the Servicer in making any P&I
      Advance required to be made by the Servicer under the Servicing Agreement.
      

    


    (b) Any
      termination by the Trustee of the Servicer’s rights and powers pursuant to the
      Servicing Agreement shall not be effected unless or until the Trustee shall
      have
      assumed all of the rights and obligations of the Servicer under the Servicing
      Agreement or shall have appointed, with the consent of the Rating Agencies
      and
      in accordance with the applicable provisions of the Servicing Agreement, a
      new
      Fannie Mae- or FHLMC-approved Person to serve as successor to the Servicer
      and
      such successor to the Servicer has accepted such appointment; provided,
      however,
      that it
      is understood and agreed by the parties hereto that there will be a period
      of
      transition (not to exceed 90 days) before the actual servicing functions can
      be
      fully transferred to a successor servicer. Upon appointment of a successor
      servicer, as authorized under this Section 4.03(b), unless the successive
      servicer shall have assumed the obligations of the terminated Servicer under
      the
      Servicing Agreement, the Trustee and such successor servicer shall enter into
      a
      servicing agreement in a form substantially similar to the affected Servicing
      Agreement. In connection with any such appointment, the Trustee may make such
      arrangements for the compensation of such successor servicer as it and such
      successor servicer shall agree, but in no event shall such compensation of
      any
      successor servicer be in excess of that payable to the Servicer under the
      Servicing Agreement. If the Trustee assumes the servicing of the Mortgage Loans,
      it will not assume liability for the representations or warranties of the
      Servicer it replaces or for the actions, errors or omissions of such
      Servicer.

    


    (c) Upon
      any
      termination of the Servicer’s rights and powers pursuant to the Servicing
      Agreement, the Trustee shall promptly notify each Rating Agency and the
      Depositor, specifying in such notice that the successor servicer has succeeded
      the Servicer under the Servicing Agreement (or under any other servicing
      agreement reasonably satisfactory to the Trustee and the Rating Agencies),
      which
      notice shall also specify the name and address of any such successor
      servicer.

    (d) The
      Depositor shall not consent to the assignment by the Servicer of the Servicer’s
      rights and obligations under the Servicing Agreement without the prior written
      consent of the Trustee, which consent shall not be unreasonably
      withheld.

    


    (e) The
      Trustee shall execute and deliver, at the written request of the Servicer,
      and
      furnish to the Servicer, at the expense of the requesting party, a power of
      attorney in the standard form provided by the Trustee to take title to the
      Mortgaged Properties after foreclosure in the name of and on behalf of the
      Trustee and for the purposes described herein to the extent necessary or
      desirable to enable the Servicer to perform its duties. The Trustee shall not
      be
      liable for the actions of the Servicer under such powers of attorney or under
      its Servicing Agreement.

      The

        the
        Trustee’s customer service desk at (312) 904-4373. Certificateholders and other
        parties that are unable to use the website are entitled to have a paper copy
        mailed to them via first class mail by contacting the Trustee and indicating
        such. In preparing or furnishing the foregoing reports, the Trustee shall
        be
        entitled to rely conclusively on the accuracy and completeness of the
        information or data regarding the Mortgage Loans and the related REO Properties
        that has been provided to the Trustee by the Servicer, without any independent
        investigation, and the Trustee shall not be obligated to verify, recompute,
        reconcile or recalculate any such information or data.


    

    Upon
      the
      reasonable advance written request of any Certificateholder that is a savings
      and loan, bank or insurance company, the Trustee shall provide, or cause to
      be
      provided, (or, to the extent that such information or documentation is not
      required to be provided by the Servicer under the Servicing Agreement, shall
      use
      reasonable efforts to obtain such information and documentation from the
      Servicer, and provide) to such Certificateholders such reports and access to
      information and documentation regarding the Mortgage Loans as such
      Certificateholders 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 an investment in the Certificates;
provided,
      however,
      that
      the Trustee shall be entitled to be reimbursed by such Certificateholders for
      the Trustee’s actual expenses incurred in providing such reports and
      access.

    


    For
      all
      purposes of this Agreement, with respect to any Mortgage Loan, delinquencies
      shall be determined and reported based on the so-called “OTS” methodology for
      determining delinquencies on mortgage loans similar to the Mortgage Loans.
      By
      way of example, a Mortgage Loan would be delinquent with respect to a Scheduled
      Payment due on a Due Date if such Scheduled Payment is not made by the close
      of
      business on the Mortgage Loan’s next succeeding Due Date, and a Mortgage Loan
      would be more than 30-days Delinquent with respect to such Scheduled Payment
      if
      such Scheduled Payment were not made by the close of business on the Mortgage
      Loan’s second succeeding Due Date. The Servicer hereby represents and warrants
      to the Depositor that this delinquency recognition policy is not less
      restrictive than any delinquency recognition policy established by the primary
      safety and soundness regulator, if any, of the Servicer.

      utilized by the Trustee and determined by the Trustee to be “participating in a
      servicing function” within the meaning of Item 1122 of Regulation AB (in each
      case, a “Servicing Function Participant”), to deliver, each at its own expense,
      to the Depositor and the Trustee, a report on an assessment of compliance with
      the Servicing Criteria applicable to it that contains (A) a statement by such
      party of its responsibility for assessing compliance with the Servicing Criteria
      applicable to it, (B) a statement that such party used the Servicing Criteria
      to
      assess compliance with the applicable Servicing Criteria, (C) such party’s
      assessment of compliance with the applicable Servicing Criteria as of and for
      the period ending the end of the fiscal year covered by the Form 10-K required
      to be filed pursuant to Section 6.14 of the Trust Agreement, including, if
      there
      has been any material instance of noncompliance with the applicable 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 Person’s assessment of compliance with the applicable
      Servicing Criteria as of and for such period. Each such assessment of compliance
      report shall be addressed to the Depositor and signed by an authorized officer
      of the applicable company, and shall address each of the applicable Servicing
      Criteria set forth on Exhibit N hereto, or as set forth in the notification
      furnished to the Depositor and the Trustee pursuant to Section 4.05(c). The
      Trustee and the Custodian hereby acknowledge and agree that their respective
      assessments of compliance will cover the items identified on Exhibit N hereto
      are being covered by such party. Promptly after receipt of each such report
      on
      assessment of compliance, (i) the Depositor shall review each such report and,
      if applicable, consult with the Trustee or the Custodian, as applicable,
      Servicer as to the nature of any material instance of noncompliance with the
      Servicing Criteria (and Servicing Function Participant engaged or utilized
      by
      the Trustee), as the case may be. None of the Trustee, the Custodian or
      Servicing Function Participant shall be required to cause the delivery of any
      such assessments if it has received written confirmation from the Depositor
      that
      a Form 10-K is not required to be filed in respect of the Trust for the
      preceding calendar year.

      and
      the Custodian shall cause, and the Trustee shall cause each Servicing Function
      Participant utilized by the Trustee to cause, each at its own expense, a
      registered public accounting firm (which may also render other services to
      such
      party) and that is a member of the American Institute of Certified Public
      Accountants to furnish a report to the Trustee and the Depositor, with a copy
      to
      the Rating Agencies, to the effect that (i) it has obtained a representation
      regarding certain matters from the management of such Person, which includes
      an
      assertion that such Person has complied with the Servicing Criteria applicable
      to it and (ii) on the basis of an examination conducted by such firm in
      accordance with standards for attestation engagements issued or adopted by
      the
      PCAOB, that attests to and reports on such Person’s assessment of compliance
      with the Servicing Criteria applicable to it. 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. Each such related
      accountant’s attestation report shall be made in accordance with Rules
      1-02(a)(3) and 2-02(g) of Regulation S-X under the Securities Act and the
      Exchange Act. Such report must be available for general use and not contain
      restricted use language. Promptly after receipt of each such accountants’
attestation report, the Depositor shall review the report and, if applicable,
      consult with the Trustee or the Custodian, as applicable, as to the nature
      of
      any defaults by the Trustee or the Custodian, as applicable, (and each Servicing
      Function Participant engaged or utilized by the Trustee), as the case may be,
      in
      the fulfillment of any of the Trustee’s, the Custodian’s or the applicable
      Servicing Function Participant’s obligations hereunder. None of the Trustee or
      the Custodian or the Servicing Function Participant shall be required to cause
      the delivery of any such attestation required by this paragraph in any year
      in
      which a Form 10-K is not required to be filed in respect of the Trust for the
      preceding calendar year.

      will be required to be filed in respect of the Trust for the preceeding calendar
      year, the Trustee shall notify the Depositor as to the name of each Servicing
      Function Participant utilized by it, and each such notice will specify what
      specific Servicing Criteria will be addressed in the report on assessment of
      compliance prepared by such Servicing Function Participant in each case, to
      the
      extent of any change from the prior year’s notice, if any. When the Trustee
      submits its assessment pursuant to Section 4.05(a), the Trustee will also at
      such time include the assessment (and related attestation pursuant to Section
      4.05(b)) of each Servicing Function Participant utilized by it.

              Distributions
                Generally. 

            


    

    


    (a) Subject
      to Section 7.01 respecting the final distribution on the Certificates, on
      each Distribution Date the Trustee or the Paying Agent shall make all
      distributions in accordance with this Article V. Such distributions shall be
      made by check mailed to each Certificateholder’s address as it appears on the
      Certificate Register of the Certificate Registrar or, upon written request
      made
      to the Trustee at least five Business Days prior to the related Record Date
      by
      any Certificateholder owning an aggregate initial Certificate Balance of at
      least $1,000,000, by wire transfer in immediately available funds to an account
      specified in the request and at the expense of such Certificateholder;
provided,
      however,
      that
      the final distribution in respect of any Certificate shall be made only upon
      presentation and surrender of such Certificate at the Certificate Registrar’s
      Corporate Trust Office; provided,
      further,
      that
      the foregoing provisions shall not apply to any Class of Certificates as long
      as
      such Certificate remains a Book-Entry Certificate in which case all payments
      made shall be made through the Clearing Agency and its Clearing Agency
      Participants. Notwithstanding the reduction of the Class Principal Balance
      of
      any Class of Certificates to zero, such Class will be outstanding hereunder
      (solely for the purpose of receiving distributions and not for any other
      purpose) until the termination of the respective obligations and
      responsibilities of the Depositor and the Trustee hereunder in accordance with
      Article VII. Wire transfers will 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 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 Certificate Registrar’s Corporate Trust
      Office. If any payment required to be made on the Certificates is to be made
      on
      a day that is not a Business Day, then such payment will be made on the next
      succeeding Business Day.

    (b) All
      distributions or allocations made with respect to the 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 Balances or Percentage Interests.

      to the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class B-1, Class
      B-2 and Class B-3 Certificates, in that order, 
      any
      unpaid remaining Basis Risk Carry Forward Amount for each such
      Class;

    

      (xxiv) to
        the
        Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class B-1, Class B-2,
        Class B-3, Class B-4 and Class B-5 Certificates the amount by which the
        Subordinate Interest Distribution Amount for such Distribution Date was less
        than the amount of interest accrued at the stated Pass-Through Rate for such
        Class and such Distribution Date;

        


    

    (xxv) to
      the
      Class OC Certificates, the Class OC Distributable Amount; and

    


    (xxvi) to
      the
      holders of the Class R Certificates, any remaining amounts.

    


    For
      the
      avoidance of doubt, Section 5.02(c) is intended to cause the Class OC
      Certificates to receive from amounts remaining after the application of all
      other clauses of Section 5.02(c) preceding it, an amount up to the sum of the
      Class OC Distributable Amount for that Distribution Date and any Class OC
      Distributable Amounts remaining unpaid from prior Distribution Dates and the
      Trustee shall construe Section 5.02(c) as necessary so as to accomplish such
      result.

    


    (d) On
      each
      Distribution Date, the Class P Distribution Amount received during the related
      Prepayment Period will be distributed to the holders of the Class P
      Certificates. On the Distribution Date in March 2012, the $100 held in trust
      for
      the Class P Certificates will be distributed to the holders of the Class P
      Certificates.

              Allocation
                of Losses. 

            


    

    


    (a) On
      or
      prior to each Distribution Date, the Trustee shall aggregate the information
      provided by the Servicer with respect to the total amount of Realized Losses
      for
      the related Distribution Date.

    


    (b) Any
      Applied Loss Amounts on the Mortgage Loans shall be allocated to the
      Subordinated Certificates in reverse order of their respective priorities of
      payment (beginning with the Class of Class B Certificates then outstanding
      with
      the highest numerical Class designation or, if no Classes of Class B
      Certificates are outstanding, then beginning with the Class of Class M
      Certificates then outstanding with the highest numerical Class designation)
      until the respective Class Principal Balance of each such Class is reduced
      to
      zero.

    


    (c) The
      Class
      Principal Balance of the Class of Subordinated Certificates then outstanding
      with the highest numerical Class designation shall be reduced on each
      Distribution Date by the Applied Loss Amount, if any. For the avoidance of
      doubt, no reductions will be made in the Class Principal Balance of the Senior
      Certificates in respect of Realized Losses on the Mortgage Loans.

    


    (d) Any
      Applied Loss Amounts allocated to a Class of Certificates or any reduction
      in
      the Class Principal Balance of a Class of Certificates pursuant to Section
      5.03(b) above shall be allocated among the Certificates of such Class in
      proportion to their respective Certificate Balances.

    (e) Any
      allocation of Realized Losses to a Certificate or any reduction in the
      Certificate Balance of a Certificate, pursuant to Section 5.03(b) above shall
      be
      accomplished by reducing the Certificate Balance thereof immediately following
      the distributions made on the related Distribution Date in accordance with
      the
      definition of “Certificate Balance.” 

    


    (f) For
      the
      avoidance of doubt, no Realized Losses on the Mortgage Loans shall be allocated
      to the Class P Certificates.

    


    (g) In
      the
      event of any Subsequent Recoveries, (i) such amount shall be treated as a
      Principal Prepayment and shall be included in the Available Distribution Amount
      for the Distribution Date occurring in the month following the month in which
      such recovery is received and (ii) the Certificate Balance of the Class or
      Classes to which the related Realized Loss had previously been allocated,
      whether or not such Class or Classes remain outstanding, shall be increased
      in
      direct order of priority, in each case by an amount equal to the lesser of
      (x)
      the amount of such recovery and (y) the aggregate amount of Realized Losses
      previously allocated to such Classes less amounts previously allocated to such
      Classes pursuant to this paragraph.

    


    
      	 	
              Section
                5.04

            	
              Determination
                of Pass-Through Rates for LIBOR
                Certificates.

            


    

    


    (a) On
      each
      Interest Determination Date after the initial Interest Determination Date and
      for so long as any LIBOR Certificates are outstanding, the Trustee will
      determine LIBOR on the basis of the British Bankers’ Association (“BBA”)
      “Interest Settlement Rate” for one-month deposits in U.S. dollars as found on
      Telerate Page 3750 as of 11:00 a.m. London time on each Interest Determination
      Date.

    


    (b) If
      on any
      Interest Determination Date, LIBOR cannot be determined as provided in paragraph
      (a) of this Section 5.05, the Trustee shall either (i) request each Reference
      Bank to inform the Trustee of the quotation offered by its principal London
      office for making one-month United States dollar deposits in leading banks
      in
      the London interbank market, as of 11:00 a.m. (London time) on such Interest
      Determination Date or (ii) in lieu of making any such request, rely on such
      Reference Bank quotations that appear at such time on the Reuters Screen LIBO
      Page (as defined in the International Swap Dealers Association Inc. Code of
      Standard Wording, Assumptions and Provisions for Swaps, 1986 Edition), to the
      extent available. LIBOR for the next Interest Accrual Period will be established
      by the Trustee on each interest Determination Date as follows:

    


    (i) If
      on any
      Interest Determination Date two or more Reference Banks provide such offered
      quotations, LIBOR for the next applicable Interest Accrual Period shall be
      the
      arithmetic mean of such offered quotations (rounding such arithmetic mean
      upwards if necessary to the nearest whole multiple of 1/32%).

    


    (ii) If
      on any
      Interest Determination Date only one or none of the Reference Banks provides
      such offered quotations, LIBOR for the next Interest Accrual Period shall be
      whichever is the higher of (i) LIBOR as determined on the previous Interest
      Determination Date or (ii) the Reserve Interest Rate. The “Reserve
      Interest Rate”
shall
      be the rate per annum which the Trustee determines to be either (i) the
      arithmetic mean (rounded upwards if necessary to the nearest whole multiple
      of
      1/32%) of the one-month United States dollar lending rates that New York City
      banks selected by the Trustee are quoting, on the relevant Interest
      Determination Date, to the principal London offices of at least two of the
      Reference Banks to which such quotations are, in the opinion of the Trustee,
      being so made, or (ii) in the event that the Trustee can determine no such
      arithmetic mean, the lowest one-month United States dollar lending rate which
      New York City banks selected by the Trustee are quoting on such Interest
      Determination Date to leading European banks. 

    



    
      
        
        

      

      
        67

        
          

        

      

      
        
        

      

    


    (iii) If
      on any
      Interest Determination Date the Trustee is required but is unable to determine
      the Reserve Interest Rate in the manner provided in paragraph (b) above, LIBOR
      for the related Classes of Certificates shall be LIBOR as determined on the
      preceding applicable Interest Determination Date.

    


    (iv) In
      the case of the first Distribution Date, LIBOR shall be 5.3200%.

    


    Until
      all
      of the LIBOR Certificates are paid in full, the Trustee will at all times retain
      at least four Reference Banks for the purpose of determining LIBOR with respect
      to each Interest Determination Date. The Trustee initially shall designate
      the
      Reference Banks. Each “Reference
      Bank”
shall
      be a leading bank engaged in transactions in Eurodollar deposits in the
      international Eurocurrency market, shall not control, be controlled by, or
      be
      under common control with, the Trustee and shall have an established place
      of
      business in London. If any such Reference Bank should be unwilling or unable
      to
      act as such or if the Trustee should terminate its appointment as Reference
      Bank, the Trustee shall promptly appoint or cause to be appointed another
      Reference Bank. The Trustee shall have no liability or responsibility to any
      Person for (i) the selection of any Reference Bank for purposes of determining
      LIBOR or (ii) any inability to retain at least four Reference Banks which is
      caused by circumstances beyond its reasonable control.

    


    (c) The
      Pass-Through Rate for each Class of LIBOR Certificates for each Interest Accrual
      Period shall be determined by the Trustee on each Interest Determination Date
      so
      long as the LIBOR Certificates are outstanding on the basis of LIBOR and the
      respective formulae appearing in footnotes corresponding to the LIBOR
      Certificates in the table relating to the Certificates in the Preliminary
      Statement.

    


    (d) In
      determining LIBOR, any Pass-Through Rate for the LIBOR Certificates, any
      Interest Settlement Rate, or any Reserve Interest Rate, the Trustee may
      conclusively rely and shall be protected in relying upon the offered quotations
      (whether written, oral or on the Dow Jones Markets) from the BBA designated
      banks, the Reference Banks or the New York City banks as to LIBOR, the Interest
      Settlement Rate or the Reserve Interest Rate, as appropriate, in effect from
      time to time. The Trustee shall not have any liability or responsibility to
      any
      Person for (i) the selection of New York City banks for purposes of determining
      any Reserve Interest Rate or (ii) its inability, following a good-faith
      reasonable effort, to obtain such quotations from, the BBA designated banks,
      the
      Reference Banks or the New York City banks or to determine such arithmetic
      mean,
      all as provided for in this Section 5.04.

    (e) The
      establishment of LIBOR and each Pass-Through Rate for the LIBOR Certificates
      by
      the Trustee shall (in the absence of manifest error) be final, conclusive and
      binding upon each Holder of a Certificate and the Trustee.

    CONCERNING
      THE TRUSTEE; EVENTS OF DEFAULT

    


    
      	 	
              Section
                6.01

            	
              Duties
                of Trustee. 

            


    

    


    (a) The
      Trustee 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.

    


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

    


    (i) The
      Trustee shall not have any liability arising out of or in connection with this
      Agreement, except for its negligence or willful misconduct. No provision of
      this
      Agreement shall be construed to relieve the Trustee from liability for its
      own
      negligent action, its own negligent failure to act or its own willful
      misconduct; provided,
      however,
      that:

    


    (ii) 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
      indemnity reasonably satisfactory to it against such risk or liability is not
      reasonably assured to it; and

    


    (iii) The
      Trustee shall not be responsible for any act or omission of the Depositor,
      the
      Seller, the Servicer or any Custodian (unless the Trustee and the Custodian
      are
      the same Person).

    


    (c) 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.

    (d) 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 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 or the Acknowledgements.

    


    (e) 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 indemnity reasonably
      satisfactory to it 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 Servicer under this Agreement or the Servicing
      Agreement.

    


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

    


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

    


    (h) 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.

    


    (i) 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.

    


    For
      all
      purposes under this Agreement, the Trustee shall not be deemed to have any
      notice of any event of default under a Servicing Agreement 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 of the Trustee, and such notice references the Holders
      of
      the Certificates and this Agreement.

    Except
      as
      otherwise provided in Section 6.01:

    


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

    


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

    


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

    


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

    


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

    


    (vi) The
      Trustee shall not be under any obligation to exercise any of the trusts or
      powers vested in it by this Agreement or the Acknowledgements or to institute,
      conduct or defend any litigation hereunder or in relation hereto, in each case
      at the request, order or direction of any of the Certificateholders pursuant
      to
      the provisions of this Agreement, unless such Certificateholders shall have
      offered to the Trustee security or indemnity reasonably satisfactory to it

    The
      Trustee makes no representations as to the validity or sufficiency of this
      Agreement, any Purchase Agreement, the Servicing Agreement, the Custodial
      Agreements or Acknowledgement or of the Certificates (other than the certificate
      of authentication on the Certificates) or of any Mortgage Loan, or related
      document save that the Trustee represents that, assuming due execution and
      delivery by the other parties hereto, this Agreement has been duly authorized,
      executed and delivered by it and constitutes its valid and binding obligation,
      enforceable against it in accordance with its terms except that such
      enforceability may be subject to (A) applicable bankruptcy and insolvency
      laws and other similar laws affecting the enforcement of the rights of creditors
      generally, and (B) general principles of equity regardless of whether such
      enforcement is considered in a proceeding in equity or at law. The Trustee
      shall
      not be accountable for the use or application by the Depositor of funds paid
      to
      the Depositor in consideration of the assignment of the Mortgage Loans to the
      Trust Fund by the Depositor or for the use or application of any funds deposited
      into the Distribution Account or any other fund or account maintained with
      respect to the Certificates. The Trustee shall not be responsible for the
      legality or validity of this Agreement or any other document or agreement
      described in this Section 6.03 or the validity, priority, perfection or
      sufficiency of the security for the Certificates issued or intended to be issued
      hereunder. The Trustee shall not have any responsibility for filing any
      financing or continuation statement in any public office at any time or to
      otherwise perfect or maintain the perfection of any security interest or lien
      granted to it hereunder or to record this Agreement.

                Requirements for Trustee. 

            


    

    


    The
      Trustee hereunder shall at all times be a corporation or association organized
      and doing business under the laws of a state or the United States of America,
      authorized under such laws to exercise corporate trust powers, having a combined
      capital and surplus of at least $50,000,000, subject to supervision or
      examination by federal or state authority and with a credit rating which would
      not cause any of the Rating Agencies to reduce their respective then current
      ratings of the Certificates (or having provided such security from time to
      time
      as is sufficient to avoid such reduction) as evidenced in writing by each Rating
      Agency. If such corporation or association publishes reports of condition at
      least annually, pursuant to law or to the requirements of the aforesaid
      supervising or examining authority, then for the purposes of this Section 6.05
      the combined capital and surplus of such corporation or association shall be
      deemed to be its combined capital and surplus as set forth in its most recent
      report of condition so published. In case at any time the Trustee shall cease
      to
      be eligible in accordance with the provisions of this Section 6.05, the Trustee
      shall resign immediately in the manner and with the effect specified in Section
      6.06 hereof. The entity serving as Trustee may have normal banking and trust
      relationships with the Depositor, the Seller, the Servicer, each Custodian
      and
      their respective affiliates.

    


    The
      Trustee (i) may not be an Originator, Servicer, the Depositor or an affiliate
      of
      the Depositor, (ii) must be authorized to exercise corporate trust powers under
      the laws of its jurisdiction of organization, and (iii) must be rated at least
      "A/A1" by S&P or the equivalent rating by Moody's (or such rating acceptable
      to S&P and Moody’s pursuant to a written confirmation). If at any time the
      Trustee shall cease to be eligible in accordance with the provisions of this
      Section 6.05, the Trustee shall resign in the manner and with the effect
      specified in Section 6.06.

              Resignation
                and Removal of Trustee. 

            


    

    


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

    


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

    (c) The
      Holders of more than 50% of the Class Principal Balance (or Percentage Interest)
      of each Class of Certificates may at any time upon 30 days’ written notice to
      the Trustee and to the Depositor remove the Trustee by such written instrument,
      signed by such Holders or their attorney-in-fact duly authorized, one copy
      of
      which instrument shall be delivered to the Depositor, one copy to the Trustee
      and one copy to the Servicer; the Depositor shall thereupon appoint a successor
      trustee in accordance with this Section 6.06.

    


    (d) Any
      resignation or removal of the Trustee and appointment of a successor trustee
      pursuant to any of the provisions of this Section shall become effective upon
      acceptance of appointment by the successor trustee, as provided in
      Section 6.07. If no successor trustee shall have been so appointed and
      shall have accepted appointment within 30 days after such notice of dismissal,
      the Trustee who received such notice of dismissal may petition any court of
      competent jurisdiction for the appointment of a successor trustee.

    (a) Any
      successor trustee appointed as provided in Section 6.06 shall execute,
      acknowledge and deliver to the Depositor 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 all Trustee Mortgage
      Files and documents and statements related to each Trustee 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 Depositor 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 6.07
      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
      6.07, such successor trustee shall mail notice of the succession of such trustee
      hereunder to all Holders of Certificates at their addresses as shown in the
      Certificate Register and to any Rating Agency. The costs of such mailing shall
      be borne by the Trustee.

      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

                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 Balance
      (or
      Percentage Interest) of every Class of Certificates shall have the power from
      time to time to appoint one or more Persons, approved by the Trustee, to act
      either as co-trustees jointly with the Trustee, or as separate trustees, or
      as
      custodians, for the purpose of holding title to, foreclosing or otherwise taking
      action with respect to any Mortgage Loan outside the state where the Trustee
      has
      its principal place of business where such separate trustee or co-trustee is
      necessary or advisable (or the Trustee has been advised by the 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. 

    


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

    


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

    


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

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

    


    (iv) the
      Trustee may at any time, by an instrument in writing executed by it, with the
      concurrence of the Depositor, 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
      Servicer.

    


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

    


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

    


    (f) The
      Trust
      shall pay the reasonable compensation of the co-trustees (which compensation
      shall not reduce any compensation payable to the Trustee under such
      Section).

                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. In the absence
      of any such appointment, references herein to the Authenticating Agent shall
      mean the Trustee. 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

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

    


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

    The
      Trustee (in its individual capacity and in its capacity as trustee hereunder)
      and its directors, officers, employees and agents shall be entitled to

      its
      agents or counsel), incurred without negligence or willful misconduct on their

      notice thereof promptly after the Trustee shall have knowledge
      thereof;

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

    


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

                Filings

            


    

    


    (a)
      The
      Trustee shall reasonably cooperate with the Depositor in connection with the
      reporting requirements of the Trust under the Exchange Act. The Trustee shall
      prepare for execution by the Depositor any Forms 8-K (other than the initial
      report on Form 8-K), 10-D and 10-K required by the Exchange Act and the rules
      and regulations of the Commission thereunder, in order to permit the timely
      filing thereof pursuant to the terms of this Section 6.14, and the Trustee
      shall
      file (via the Commission’s Electronic Data Gathering and Retrieval System) such
      Forms executed by the Depositor. The Trustee shall have no duty to verify
      information received by it from other Persons (other than Subcontractors
      utilized by the Trustee) in connection with its duties under this Section
      6.14.

    


    (b)
      Within 15 calendar days after each Distribution Date (subject to permitted
      extensions under the Exchange Act), the Trustee shall prepare and file on behalf
      of the Trust 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 Monthly Statement attached thereto. Any disclosure in
      addition to the Monthly Statement that is required to be included on Form 10-D
      (“Additional Form 10-D Disclosure”) shall be prepared by the party responsible
      for preparing such disclosure as set forth on Exhibit O hereto and the Trustee
      shall compile such disclosure pursuant to the following paragraph. The Trustee
      will have no duty or liability for any failure hereunder to determine, prepare
      or file any Additional Form 10-D Disclosure, except as set forth in the next
      paragraph.

    


    As
      set
      forth on Exhibit O hereto, within 5 calendar days after the related Distribution
      Date, certain parties to this Agreement shall be required to provide to the
      Trustee and the Depositor, to the extent known by such applicable parties,
      any
      Additional Form 10-D Disclosure, if applicable. In addition, the Servicer is
      obligated under the Servicing Agreement to provide certain information to the
      Trustee. The Trustee shall compile all such information provided to it in a
      Form
      10-D prepared by it.

    After
      preparing the Form 10-D, the Trustee shall forward electronically a draft copy
      of the Form 10-D to the Depositor for review, verification and execution by
      the
      Depositor. No later than 2 Business Days prior to the 15th calendar day after
      the related Distribution Date, an officer of the Depositor 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 Section
      6.14(f)(ii). The signing party at the Depositor can be contacted at the
      Depositor’s address for notices set forth in Section 10.07, or such other
      address as to which the Depositor has provided prior written notice to the
      Trustee. The Depositor acknowledges that the performance by the Trustee of
      its
      duties under this Section 6.14(b) related to the timely preparation and filing
      of Form 10-D is contingent upon the Servicer, the Depositor and any other Person
      obligated to provide Additional Form 10-D Disclosure as set forth on Exhibit
      O
      hereto observing all applicable deadlines in the performance of their duties
      under this Section 6.14(b) or the applicable provisions of the Servicing
      Agreement. 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 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 party hereto or the Servicer or Custodian (other than the Trustee
      or
      any Subcontractor utilized by the Trustee) needed to prepare, arrange for
      execution or file such Form 10-D, not resulting from its own negligence, bad
      faith or willful misconduct.

    


    (c)
      Within 90 days after the end of each fiscal year of the Trust or such earlier
      date as may be required by the Exchange Act (the “10-K Filing Deadline”),
      commencing in March 2007, the Trustee shall prepare and file on behalf of the
      Trust 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 Trustee within the applicable time frames set
      forth in this Agreement, (i) an annual compliance statement for the Servicer,
      and each Subservicer engaged by the Servicer, and the Trustee, (ii)(A) the
      annual reports on assessment of compliance with servicing criteria for the
      Trustee, the Servicer, the Custodian, each Subservicer engaged by the Servicer
      and each Servicing Function Participant utilized by the Servicer or the Trustee,
      and (B) if any such report on assessment of compliance with servicing criteria
      identifies any material instance of noncompliance, disclosure identifying such
      instance of noncompliance, or such report on assessment of compliance with
      servicing criteria 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, (iii)(A) the registered public accounting firm attestation report
      for
      the Trustee, the Servicer, the Custodian, each Subservicer engaged by the
      Servicer and each Servicing Function Participant utilized by the Servicer,
      or
      the Trustee, and (B) if any registered public accounting firm attestation report
      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 (iv) a certification in the form attached hereto as Exhibit L,
      with such changes as may be necessary or appropriate as a result of changes
      promulgated by the Commission (the “Sarbanes Certification”), which shall be
      signed by the senior officer of the Depositor in charge of securitization.
      Any
      disclosure or information in addition to (i) through (iv) above that is required
      to be included on Form 10-K (“Additional Form 10-K Disclosure”) shall be
      prepared by party responsible for preparing such disclosure as set forth on
      Exhibit P hereto, and the Trustee shall compile such disclosure pursuant to
      the
      following paragraph. 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.

    As
      set
      forth on Exhibit P hereto, no later than March 15th of
      each
      year that the Trust is subject to the Exchange Act reporting requirements,
      commencing in 2007, certain parties to this Agreement and the Servicer and
      the
      Custodian shall be required to provide to the Trustee and the Depositor, to
      the
      extent known by such applicable parties, any Additional Form 10-K Disclosure,
      if
      applicable. In addition, the Servicer is obligated under the Servicing Agreement
      to provide certain information to the Trustee. The Trustee shall compile all
      such information provided to it in a Form 10-K prepared by it.

    


    After
      preparing the Form 10-K, the Trustee shall forward electronically a draft copy
      of the Form 10-K to the Depositor for review, verification and execution by
      the
      Depositor. No later than 5:00 p.m. EST on the 3rd Business Day prior to the
      10-K
      Filing Deadline, an officer of the Depositor 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 Section 6.14(f)(ii). The signing
      party at the Depositor can be contacted at the Depositor’s address for notices
      set forth in Section 10.07, or such other address as to which the Depositor
      has
      provided prior written notice to the Trustee. The Depositor acknowledges that
      the performance by the Trustee of its duties under this Section 6.14(c) related
      to the timely preparation and filing of Form 10-K is contingent upon the
      Servicer (and any Subservicer or Servicing Function Participant engaged by
      the
      Servicer) and the Depositor and any other Person obligated to provide Additional
      Form 10-K Disclosure as set forth on Exhibit P hereto, observing all applicable
      deadlines in the performance of their duties under this Section 6.14(c), Section
      6.14(d), or the applicable provisions of the Servicing Agreement. 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
      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 party hereto
      (other than the Trustee or any Subcontractor utilized by the Trustee) needed
      to
      prepare, arrange for execution or file such Form 10-K, not resulting from its
      own negligence, bad faith or willful misconduct.

    


    (d)
      In
      connection with the execution of a Sarbanes Certification, the Trustee shall
      sign a certification (in the form attached hereto as Exhibit M, with such
      changes as may be necessary or appropriate as a result of changes promulgated
      by
      the Commission) for the benefit of the Depositor and its officers, directors
      and
      Affiliates, and the Servicer shall sign a certification solely with respect
      to
      the Servicer (in the form attached to the Servicing Agreement, with such changes
      as may be necessary or appropriate as a result of changes promulgated by the
      Commission) for the benefit of the Depositor, the Trustee and their respective
      officers, directors and Affiliates. Each such certification shall be delivered
      to the Depositor no later than March 10th of each year (or if such day is not
      a
      Business Day, the immediately preceding Business Day) and the Depositor shall
      deliver the Sarbanes Certification no later than the time set forth for the
      delivery to the Trustee of the signed Form 10-K pursuant to Section 6.14(d)
      for
      such year. In the event that prior to the filing date of the Form 10-K in March
      of each year, the Trustee or the Servicer has actual knowledge of information
      material to the Sarbanes Certification, that party shall promptly notify the
      Depositor and each of the other parties signing the certifications. In addition,
      the Trustee shall indemnify and hold harmless the Depositor and the Sponsor
      and
      their officers, directors, employees, agents and Affiliates from and against
      any
      losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
      fees and related costs, judgments and other costs and expenses arising out
      of or
      based upon any breach of the Trustee’s obligations under this Section 6.14(d) or
      any material misstatement or material omission contained in any information,
      report, certification or other material provided by the Trustee in written
      or
      electronic form pursuant to Section 6.14 of this Agreement and Exhibits O,
      P and
      Q to this Agreement provided by the Trustee (excluding any information, report,
      accountants’ letter, certification or other materials provided in written or
      electronic form by or on behalf of any Person other than the Trustee or any
      Subcontractor utilized by the Trustee), which results from negligence, bad
      faith
      or willful misconduct on the part of the Trustee in connection therewith. If
      the
      indemnification provided for herein is unavailable or insufficient to hold
      harmless any indemnified party, then the Trustee agrees in connection with
      a
      breach of the Trustee’s obligations under this Section 6.14(d) or any material
      misstatement or material omission contained in any information, report,
      certification or other material provided in written or electronic form pursuant
      to Section 6.14 of this Agreement and Exhibits O, P and Q to this Agreement
      provided by or on behalf of the Trustee (excluding any information, report,
      certification, accountants’ letter or other materials provided in written or
      electronic form by or on behalf of any Person other than the Trustee or any
      Subcontractor utilized by the Trustee), results from the negligence, bad faith
      or willful misconduct on the part of the Trustee in connection therewith that
      it
      shall contribute to the amount paid or payable by the Depositor and the Sponsor
      as a result of the losses, claims, damages or liabilities of the Depositor
      and
      the Sponsor in such proportion as is appropriate to reflect the relative fault
      of the Depositor and the Sponsor on the one hand and the Trustee on the
      other.

    (e)
      Upon
      any filing with the Commission, the Trustee shall promptly deliver to the
      Depositor a copy of each such executed report, statement or
      information.

    


    (f)
      (i)
      The obligations set forth in paragraphs (a) through (d) of this Section shall
      only apply with respect to periods for which reports are required to be filed
      with respect to the Trust under the Exchange Act. Prior to January 30 of the
      first year in which the Trustee is able to do so under applicable law, the
      Trustee shall file a Form 15 Suspension Notification with respect to the Trust,
      with a copy to the Depositor. At any time after the filing of a Form 15
      Suspension Notification, if the number of Holders of the Offered Certificates
      of
      record exceeds the number set forth in Section 15(d) of the Exchange Act or
      the
      regulations promulgated pursuant thereto which would cause the Trust to again
      become subject to the reporting requirements of the Exchange Act, the Trustee
      shall recommence preparing and filing reports on Form 10-K, 10-D and 8-K as
      required pursuant to this Section 6.14 and the parties hereto shall again have
      the obligations set forth in this Section, in Section 12 of the Custodial
      Agreement and Section 5.04 of the Servicing Agreement.

    (ii)
      In
      the event that the Trustee is 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 pursuant
      to 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, the Trustee will immediately notify the Depositor and the
      Servicer. In the case of Form 10-D and 10-K, the Depositor, the Servicer and
      the
      Trustee will thereupon cooperate to prepare and file a Form 12b-25 and a 10-DA
      and 10-KA 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 disclosure information
      required to be included on Form 8-K, include such disclosure information on
      the
      next Form 10-D. In the event that any previously filed Form 8-K, 10-D or 10-K
      needs to be amended, the party to this Agreement deciding that an amendment
      to
      such Form 8-K, 10-D or 10-K is required will notify the Depositor, the Trustee
      and the Servicer and such parties will cooperate to prepare any necessary Form
      8-KA, 10-DA or 10-KA. Any Form 15, Form 12b-25 or any amendment to Form 8-K,
      10-D or 10-K shall be signed by an officer of the Depositor. The Depositor
      acknowledges that the performance by the Trustee of its duties under this
      Section 6.14(f) related to the timely preparation and filing of Form 15, a
      Form
      12b-25 or any amendment to Form 8-K, 10-D or 10-K is contingent upon the
      Servicer, the Depositor observing all applicable deadlines in the performance
      of
      their duties under this Section 6.14 or the applicable provisions of the
      Servicing Agreement. 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 the Depositor,
      the
      Servicer or the Custodian (other than the Trustee or any Subcontractor utilized
      by the Trustee) needed to prepare, arrange for execution or file such Form
      15,
      Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, not resulting from
      its
      own negligence, bad faith or willful misconduct.

    


    (g)
      Within four (4) Business Days after the occurrence of an event requiring
      disclosure on Form 8-K (each such event, a “Reportable
      Event”),
      and
      also if requested by the Depositor, the Trustee shall prepare and file on behalf
      of the Trust 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 prepared by the party responsible for preparing such
      disclosure as set forth on Exhibit Y hereto and compiled by the Trustee pursuant
      to the following paragraph. 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.

    


    As
      set
      forth on Exhibit Q hereto, for so long as the Trust is subject to the Exchange
      Act reporting requirements, no later than noon on the 2nd Business Day after
      the
      occurrence of a Reportable Event, certain parties to this Agreement and the
      Servicer under the Servicing Agreement shall be required to provide to the
      Depositor and the Trustee, to the extent known by such applicable parties,
      any
      Form 8-K Disclosure Information, if applicable. In addition, the Servicer is
      obligated under the Servicing Agreement to provide certain information to the
      Trustee. The Trustee shall compile all such information provided to it in a
      Form
      8-K prepared by it.

    After
      preparing the Form 8-K, the Trustee shall forward electronically a draft copy
      of
      the Form 8-K to the Depositor for review, verification and execution by the
      Depositor. No later than the end of the 3rd Business Day after the Reportable
      Event, an officer of the Depositor 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 Section 6.14(f)(ii). The signing party at
      the
      Depositor can be contacted at the Depositor’s address for notices set forth in
      Section 10.07, or such other address as to which the Depositor has provided
      prior written notice to the Trustee. The Depositor acknowledges that the
      performance by the Trustee of its duties under this Section 6.14(g) related
      to
      the timely preparation and filing of Form 8-K is contingent upon the Servicer,
      the Depositor and any other Person obligated to provide Form 8-K Disclosure
      Information as set forth on Exhibit Q hereto, observing all applicable deadlines
      in the performance of their duties under this Section 6.14(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 party hereto (other than
      the Trustee or any Subcontractor utilized by the Trustee) needed to prepare,
      arrange for execution or file such Form 8-K, not resulting from its own
      negligence, bad faith or willful misconduct.

    


    (h)
      The
      Trustee shall have no liability for any loss, expense, damage or claim arising
      out of or resulting from (i) the accuracy or inaccuracy of any Additional Form
      10-D Disclosure, Additional Form 10-K Disclosure or Form 8-K Disclosure
      Information (excluding any information therein provided by the Trustee or any
      Subcontractor utilized by the Trustee) provided to the Trustee in connection
      with the preparation of Forms 10-D, 10-K and 8-K pursuant to this Section 6.14,
      or (ii) the failure of the Depositor to timely execute and return for filing
      any
      Forms 10-D, 10-K and 8-K required to be filed by the Trustee pursuant to this
      Section 6.14, in either case, not resulting from the Trustee’s own negligence,
      bad faith or misconduct.

    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. 

            


    

    


    (a) The
      obligations and responsibilities of the Trustee created hereby (other than
      the
      obligation of the Trustee to make payments to the Certificateholders as set
      forth in Section 7.02), 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 or
      auction of the property held by the Trust Fund in accordance with
      Section 7.01(b) or 7.01(c) and (iii) the Latest Possible Maturity
      Date; provided,
      however,
      that in
      no event shall the Trust Fund created hereby continue beyond the expiration
      of
      21 years from the death of the last survivor of the descendants of Joseph P.
      Kennedy, the late Ambassador of the United States to the Court of St. James’s,
      living on the date hereof. Any termination of the Trust Fund shall be carried
      out in such a manner so that the termination of each REMIC included therein
      shall qualify as a “qualified liquidation” under the REMIC
      Provisions.

    


    (b) On
      the
      Initial Optional Termination Date, at the option of and in consultation with
      the
      Depositor, the Auction Administrator shall solicit bids for the Pool Assets
      from
      at least three institutions that are regular purchasers and/or sellers in the
      secondary market of residential whole mortgage loans similar to the Mortgage
      Loans. If the Auction Administrator receives at least three bids for the Pool
      Assets, and one of such bids is equal to or greater than the Minimum Auction
      Price, the Auction Administrator shall sell the related Pool Assets to the
      highest bidder (the “Auction
      Purchaser”)
      at the
      price offered by the Auction Purchaser (the “Mortgage
      Loan Auction Price”).
      If
      the Auction Administrator receives less than three bids, or does not receive
      any
      bid that is at least equal to the Minimum Auction Price, unless the Servicer
      exercises its option under subsection (c) below, the Auction Administrator
      shall, on each six-month anniversary of the initial Optional Termination Date,
      repeat these auction procedures until the Auction Administrator receives a
      bid
      that is at least equal to the Minimum Auction Price, at which time the Auction
      Administrator shall sell the Pool Assets to the Auction Purchaser at that
      Mortgage Loan Auction Price; provided,
      however,
      that
      the Auction Administrator shall not be required to repeat these auction
      procedures on any Distribution Date for any six-month anniversary of the initial
      Optional Termination Date unless the Auction Administrator reasonably believes
      that there is a reasonable likelihood of receiving a bid of at least the Minimum
      Auction Price. The Auction Administrator shall give notice to the Rating
      Agencies and the Servicer that is servicing any of the Mortgage Loans of the
      sale of the Pool Assets pursuant to this Section 7.01(b) (an “Auction
      Sale”)
      and of
      the date of such auction (the “Auction
      Date”).
      The
      Trustee may engage an investment banking firm and/or other agents in connection
      with the Auction, the cost of which shall be included in the Minimum Auction
      Price (unless an Optional Termination does not occur in which case such costs
      shall be an expense of the Trust Fund); provided, however, that any such
      engagement and the choice of any such investment banking firm and/or other
      agents shall be subject to the consent of the Depositor.

    (c) On
      any
      Distribution Date occurring after the Initial Optional Purchase Date, the
      Servicer shall have the option to cause the Trust Fund to adopt a plan of
      complete liquidation of the Mortgage Loans pursuant to Sections 7.02 and
      7.03 hereof to sell all of the property related thereto. If the Servicer elects
      to exercise such option, it shall no later than 30 days prior to the
      Distribution Date selected for purchase of the Mortgage Loans and all other
      assets of the Trust Fund (the “Purchase
      Date”)
      deliver written notice to the Trustee and either (a) deposit in the
      Distribution Account the related Redemption Price or (b) state in such
      notice that the Redemption Price shall be deposited in the Distribution Account
      not later than 10:00 a.m., New York City time, on the applicable Purchase Date.
      Upon exercise of such option, the property of the Trust Fund shall be sold
      to
      the Servicer at a price equal to the related Redemption Price. 

    


    (d) The
      Depositor, the Servicer, the Trustee and each Custodian shall be reimbursed
      from
      the Redemption Price for any P&I Advances, Servicer Advances, accrued and
      unpaid Servicing Fees or other amounts with respect to the Mortgage Loans and
      any related assets being purchased pursuant to Section 7.01(b) or 7.01(c) above
      that are reimbursable to such parties (and such other amounts which, if not
      related to the Mortgage Loans and other assets of the Trust Fund not being
      purchased, that are then due and owing to any such Person) under this Agreement
      and the Servicing Agreement or the related Custodial Agreement.

              Procedure
                Upon Redemption of Trust Fund. 

            


    

    


    (a) Notice
      of
      any termination pursuant to the provisions of Section 7.01, specifying the
      Distribution Date upon which the final distribution shall be made or the
      purchase of the Trust’s assets will occur, shall be given promptly by the
      Trustee by first class mail to the Certificateholders mailed in the case of
      a
      redemption of the Certificates, no later than (i) the first day of the month
      in
      which the Distribution Date selected for redemption of such Certificates shall
      occur or (ii) upon (x) the sale of all of the property of the Trust Fund by
      the Trustee or in the case of a sale of assets of the Trust Fund, 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
      Initial Optional Purchase Date, 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 Certificate Registrar’s 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 Certificate
      Registrar, if not the Trustee, at the time such notice is given to Holders
      of
      the Certificates. Upon any such termination, the duties of the Certificate
      Registrar with respect to the affected Certificates shall terminate and the
      Trustee shall terminate the Distribution 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.

    


    (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 deliver any remaining funds being held by it to the Holder
      of
      the Class R Certificates and the Holder of the Class R Certificates 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 7.02. The foregoing provisions are intended to distribute to each
      Class of Certificates any accrued and unpaid interest and/or principal to which
      they are entitled based on their Pass-Through Rates and Class Certificate
      Balances set forth in the Preliminary Statement upon liquidation of the Trust
      Fund.

    (c) Any
      reasonable expenses incurred by the Trustee in connection with any purchase
      or
      termination or liquidation of the portion of the Trust Fund shall be reimbursed
      from proceeds received from the liquidation of the Trust Fund.

    


    (d) Any
      purchase of the Pool Assets by the Auction Purchaser shall be made on an Auction
      Date by receipt of the Auction Administrator of the Mortgage Loan Auction Price
      from the Auction Purchaser, and deposit of the Mortgage Loan Auction Price
      into
      the Distribution Account by the Auction Administrator before the Distribution
      Date on which such purchase is effected. Upon deposit of such purchase price
      into the Distribution Account, the Trustee shall, upon request and at the
      expense of the Auction Purchaser execute and deliver all such instruments of
      transfer or assignment, in each case without recourse, as shall be reasonably
      requested by the Auction Purchaser to vest title in the Auction Purchaser in
      the
      Pool Assets so purchased and shall transfer or deliver to the Auction Purchaser
      the purchased Pool Assets.

              Additional
                Trust Fund Termination Requirements.


            


    

    


    (a) On
      the
      termination of the Trust Fund under Section 7.01 (a), upon an Auction Sale
      pursuant to Section 7.01(b) or upon the exercise of the right to purchase all
      of
      the Mortgage Loans pursuant to Section 7.01(c), the Trustee shall comply with
      requirements of this Section 7.03 with respect to each REMIC and with respect
      to
      the Certificates, unless the party having the right to purchase the assets
      of
      the Affected REMIC (the “Purchaser”)
      delivers to the Trustee, an Opinion of Counsel (at the Servicer’s expense),
      addressed to the Trustee to the effect that the failure of the Trustee 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 making the final payment on the Certificates, (and
      upon notification by (1) the Auction Administrator in the case of a purchase
      under Section 7.01(b) or (2) the Servicer in the case of a purchase under
      Section 7.01(c)) the Trustee shall adopt on behalf of each REMIC, a plan of
      complete liquidation, meeting the requirements of a qualified liquidation under
      the REMIC Provisions;

    



    
      
        
        

      

      
        87

        
          

        

      

      
        
        

      

    


    (ii) Any
      sale
      of the assets of any REMIC shall be for cash and shall occur at or after the
      time the plan of complete liquidation is adopted and prior to the time the
      final
      payments on the Certificates are made;

    


    (iii) 
      On the
      date specified for final payment of the Certificates, the Trustee shall make
      final distributions of principal and interest on the Certificates 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 portion of the Trust Fund
      (and each REMIC) shall terminate at that time; and

    


    (i) In
      no
      event may the final payment on the Certificates or the final distribution or
      credit to the Holders of the Residual Certificates be made after the 89th day
      from the date on which the plan of complete liquidation is adopted.

    


    (b) By
      its
      acceptance of a Residual Certificate, each Holder thereof hereby agrees to
      accept the plan of complete liquidation adopted by the Trustee under this
      Section 7.03 and to take such other action in connection therewith as may be
      reasonably requested by the Trustee or the Servicer.

                Loans and Released Mortgage Loans. 

            


    

    


    Notwithstanding
      anything to the contrary contained in this Agreement, each Charged-off Loan
      that
      becomes a Released Mortgage Loan shall be released from the Trust Fund as soon
      as practicable after the Trustee has received notice in writing from the
      Servicer that a Mortgage Loan has become a Released Mortgage Loan. Upon receipt
      of such notice, the Trustee shall cause the related Custodian to release to
      the
      Released Mortgage Transferee the related Trustee Mortgage File and the Trustee
      shall execute and delivery such instruments of transfer or assignment, in each
      case without recourse, representation or warranty, as the Released Mortgage
      Transferee shall furnish to the Trustee and as shall be necessary to vest in
      such party the Mortgage Loan released pursuant hereto. Thereafter (i) the
      Released Mortgage Loan shall no longer constitute part of the Trust Fund or
      be
      an asset of any REMIC, and the Released Mortgage Transferee shall be entitled
      to
      any amounts subsequently received in respect of any such Released Mortgage
      Loans, (ii) the Released Mortgage Transferee may designate any servicer to
      service any such Released Mortgage Loan and (iii) the Released Mortgage
      Transferee may sell any such Released Mortgage Loan to a third party. For
      purposes of compliance with the REMIC Provisions, any such Released Mortgage
      Loan transferred to the Released Mortgage Transferee pursuant to this Section
      7.04 and having any value as of the date of such transfer shall be treated
      as
      having been transferred by the related REMIC as additional compensation for
      services provided to such REMIC and if no such services were provided, as an
      additional distribution to the Class OC Certificates.

                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 Trustee 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 the Holders of Certificates evidencing
      not less than 25% of the Class Principal 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 8.01, each and every Certificateholder and the Trustee shall
      be
      entitled to such relief as can be given either at law or in equity.

    (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 Certificate Registrar, 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
      Certificate Registrar shall, within five Business Days after the receipt of
      such
      application, afford such Applicants reasonable access during the normal business
      hours of the Certificate Registrar to the most recent list of Certificateholders
      held by the Certificate Registrar 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 Certificate Registrar
      and the Trustee that none of the Depositor, 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.

              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
      Owners, 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. 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, if made
      in
      the manner provided in this Section 8.03. 

    


    (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
      neither the Trustee nor 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 in
      reliance thereon, whether or not notation of such action is made upon such
      Certificate.

              Section
                9.01

            	
              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.

    


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

    


    (c) The
      Trustee shall represent the Trust Fund in any administrative or judicial
      proceeding relating to an examination or audit by any governmental taxing
      authority with respect thereto. The Trustee shall pay any and all tax related
      expenses (not including taxes) of each REMIC, including but not limited to
      any
      professional fees or expenses related to audits or any administrative or
      judicial proceedings with respect to such REMIC that involve the Internal
      Revenue Service or state tax authorities, but only to the extent that
      (i) such expenses are ordinary or routine expenses, including expenses of a
      routine audit but not expenses of litigation (except as described in (ii));
      or
      (ii) such expenses or liabilities (including taxes and penalties) are
      attributable to the negligence or willful misconduct of the Trustee in
      fulfilling its duties hereunder (including its duties as tax return preparer).
      The Trustee shall be entitled to reimbursement of expenses to the extent
      provided in clause (i) above from the Distribution Account, provided,
      however,
      the
      Trustee shall not be entitled to reimbursement for expenses incurred in
      connection with the preparation of tax returns and other reports as required
      by
      this Section 9.01.

    


    (d) The
      Trustee shall prepare, sign and 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 Trustee.
      In
      preparing such returns, the Trustee shall, with respect to each REMIC other
      than
      the Master REMIC: (i) treat the accrual period for interests in such REMIC
      as the calendar month; (ii) account for distributions made from each REMIC
      other than the Master REMIC as made on the first day of each succeeding calendar
      month; (iii) account for income under the all-OID method at the weighted
      average of the Net Mortgage Rates; (iv) use the aggregation method provided
      in Treasury Regulation section 1.1275-2(c); and (v) account for
      income and expenses related to each REMIC other than the Master REMIC in the
      manner resulting in the lowest amount of excess inclusion income possible
      accruing to the Holder of the residual interest in each such REMIC.

    



    
      
        
        

      

      
        91

        
          

        

      

      
        
        

      

    


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

    


    (f) To
      the
      extent within their control, the Trustee and the Holders of Certificates shall
      take any action or cause any REMIC to take any action necessary to 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 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 has received
      an
      Opinion of Counsel (at the expense of the party seeking to take such action)
      to
      the effect that the contemplated action will not endanger such status or result
      in the imposition of such a tax. In addition, prior to taking any action with
      respect to any REMIC or the assets therein, or causing any REMIC to take any
      action, which is not expressly permitted under the terms of this Agreement,
      any
      Holder of a Residual Certificate will consult with the Trustee or its designee,
      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 has
      advised it in writing that an Adverse REMIC Event could occur; provided,
      however,
      that if
      no Adverse REMIC Event would occur but such action could result in the
      imposition of additional taxes on the Residual Certificateholders, no such
      Person shall take any such action, or cause any REMIC to take any such action
      without the written consent of the Residual Certificateholders.

    


    (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 Paying Agent
      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, (A) out of other amounts held in the Distribution
      Account, and shall reduce amounts otherwise payable to holders of regular
      interests in any such REMIC or (B) to the extent that any such taxes are imposed
      on the REMIC as a result of the breach of any representation, warranty or
      covenant of the Trustee, then the Trustee shall pay when due any and all such
      taxes. 

    


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

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

    


    (j) The
      Trustee shall not enter into any arrangement by which any REMIC will receive
      a
      fee or other compensation for services.

    


    (k) The
      Class R Holder shall act as “tax matters person” with respect to each REMIC
      created hereunder and the Trustee shall act as agent for the Class R Holder
      in such roles, unless and until another party is so designated by the
      Class R Holder.

    


    (l) The
      Trustee shall treat the rights of the LIBOR Certificateholders to receive Basis
      Risk Carryforward Amounts as rights in an interest rate cap contract written
      by
      the Class OC Certificateholder in favor of such Certificateholders. Thus, each
      LIBOR Certificateholder shall be treated as representing not only ownership
      of
      regular interests in a REMIC, but also ownership of an interest in an interest
      rate cap contract. For tax purposes the interest rate cap contract will be
      deemed to have a value of $10,000.

    Neither
      the Depositor 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 each REMIC pursuant to Article VII of this Agreement, (iv) a
      substitution pursuant to Article II of this Agreement or (v) a repurchase
      of Mortgage Loans pursuant to Article II of this Agreement, nor acquire any
      assets for any REMIC, nor sell or dispose of any investments in the Distribution
      Account for gain, nor accept any contributions to any REMIC after the Closing
      Date, unless it has received an Opinion of Counsel (at the expense of the party
      causing such sale, disposition, substitution or acceptance) that such
      disposition, acquisition, substitution, or acceptance will not 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).

    


    The
      Trustee with respect to the Mortgage Loans shall not permit the Servicer to
      consent to any modification of any such Mortgage Loan for which the consent
      of
      the Trustee is required under the Servicing Agreement under which such Mortgage
      Loan is serviced, that would (i) increase the interest rate in respect of such
      Mortgage, defer for a period in excess of six months or forgive the payment
      of
      any principal or interest, reduce the outstanding principal amount (except
      for
      actual payments of principal), increase the Servicing Fee on such Mortgage
      Loan
      or extend the final maturity date on such Mortgage Loan, or (ii) result in
      a
      substitution or release of collateral or in the provision of additional
      collateral for the Mortgage Loan, unless the applicable Mortgage Loan is in
      default or default is reasonably foreseeable in respect of such Mortgage Loan,
      or the Trustee has received an Opinion of Counsel (at the expense of the party
      requesting consent for such modification) that such modification will not result
      in an Adverse REMIC Event.

    Upon
      the
      occurrence of an Adverse REMIC Event due to the negligent performance by the
      Trustee of its duties and obligations set forth herein, the Trustee shall
      indemnify the Certificateholders 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 Depositor or the Holder of the Residual Certificate, nor
      for
      any such Losses resulting from misinformation provided by any of the foregoing
      parties on which the Trustee has relied. Notwithstanding the foregoing, however,
      in no event shall the Trustee have any liability (1) for any action or
      omission that is taken in accordance with and in compliance with the express
      terms of, or which is expressly permitted by the terms of, this Agreement or
      under any Purchase Agreement or Servicing Agreements or under any
      Acknowledgement, (2) for any Losses other than arising out of malfeasance,
      willful misconduct or negligent performance by the Trustee of its duties and
      obligations set forth herein, and (3) for any special or consequential
      damages to Certificateholders of the related Residual Certificate (in addition
      to payment of principal and interest on the Certificates).

    


    
      	 	
              Section
                9.04

            	
              REO
                Property. 

            


    

    


    (a) Notwithstanding
      any other provision of this Agreement, the Trustee shall not, except to the
      extent provided in the Servicing Agreement, knowingly permit (if the permission
      of the Trustee is required by the Servicing Agreement) the 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 Servicer has
      provided to the Trustee an Opinion of Counsel concluding that, under the REMIC
      Provisions, such action would not adversely affect the status of any REMIC
      as a
      REMIC and any income generated for any REMIC by the REO Property would not
      result in an Adverse REMIC Event.

    


    (b) The
      Depositor shall cause the 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 Depositor shall, or shall cause the
      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
      Depositor or the Servicer (on behalf of the Trust Fund) has received a grant
      of
      extension from the Internal Revenue Service to the effect that, under the REMIC
      Provisions and any relevant proposed legislation and under applicable state
      law,
      the REMIC may hold REO Property for a longer period without causing an Adverse
      REMIC Event. If such an extension has been received, then the Depositor, acting
      on behalf of the Trustee hereunder, shall, or shall cause the Servicer to,
      continue to attempt to sell the REO Property for its fair market value for
      such
      period longer than three years as such extension permits (the “Extended
      Period”).
      If
      such an extension has not been received and the Depositor or the Servicer,
      acting on behalf of the Trust Fund hereunder, is unable to sell the REO Property
      within 33 months after its acquisition by the Trust Fund or if such an
      extension, has been received and the Depositor or the Servicer is unable to
      sell
      the REO Property within the period ending three months before the close of
      the
      Extended Period, the Depositor shall cause the 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
      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 and the Trustee,
      without notice to or the consent of any of the Holders, (i) to cure any
      ambiguity or mistake, (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 Purchase Agreement or
      Servicing Agreement, (iii) to make any other provisions with respect to
      matters or questions arising under this Agreement or (iv) to add, delete,
      or amend any provisions to the extent necessary or desirable to comply with
      any
      requirements imposed by the Code and the REMIC Provisions. No such amendment
      effected pursuant to the preceding sentence shall, as evidenced by an Opinion
      of
      Counsel, result in an Adverse REMIC Event, nor shall such amendment effected
      pursuant to clause (iii) of such sentence adversely affect in any material
      respect the interests of any Holder. Prior to entering into any amendment
      without the consent of Holders pursuant to this paragraph, the Trustee shall
      be
      provided with an Opinion of Counsel (at the expense of the party requesting
      such
      amendment) to the effect that such amendment is permitted under this Section
      10.03. 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 the then current rating assigned to the Certificates.

    


    (b) This
      Agreement may also be amended from time to time by the Depositor and the
      Trustee, with the consent of the Holders of not less than 66-2/3% of the Class
      Principal Balance or Percentage Interest of each Class of Certificates affected
      thereby for the purpose of adding any provisions to or changing in any manner
      or
      eliminating any of the provisions of this Agreement or of modifying in any
      manner the rights of the Holders; provided,
      however,
      that no
      such amendment shall be made unless the Trustee receives an Opinion of Counsel,
      at the expense of the party requesting the change, that such change will not
      cause an Adverse REMIC Event; and provided further, that no such amendment
      may
      (i) reduce in any manner the amount of, or delay the timing of, payments
      received on Mortgage Loans which are required to be distributed on any
      Certificate, without the consent of the Holder of such Certificate or (ii)
      reduce the aforesaid percentages of Class Principal Balance 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 Balance 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

    (d) It
      shall
      not be necessary for the consent of Holders under this Section 10.03 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.

                holding such Residual Certificate as they become
                due.

            


    

     

    
      	 	
              10.

            	
              That
                the Purchaser (i) is not a Non-U.S. Person or (ii) is a Non-U.S.
                Person that holds a Residual Certificate in connection with the conduct

                in
                accordance with the requirements of the Code and the regulations
                promulgated thereunder and that such transfer of a Residual Certificate
                will not be disregarded for federal income tax purposes. “Non-U.S.
                Person”
                means an individual, corporation, partnership or other person other
                than

                this
                purpose, the District of Columbia; (iii) an estate that is subject to
                U.S. federal income tax regardless of the source of its income;
                (iv) a trust if a court within the United States is able to exercise
                primary supervision over the administration of the trust and one
                or more
                United States trustees have authority to control all substantial
                decisions
                of the trust; and, (v) to the extent provided in Treasury
                regulations, certain trusts in existence on August 20, 1996 that
                are
                treated as United States persons prior to such date and elect to
                continue
                to be treated as United States
                persons.

              The
                Purchaser will not cause income from the Residual Certificate to

                the
                Purchaser or another U.S. taxpayer.

                thereof, a Book-Entry Nominee, or a person that does not satisfy
                the
                requirements of paragraph 7 and paragraph 10
                hereof.

      the
      assessment or collection of any federal, state or local taxes legally required

      has conducted a reasonable investigation at the time of the transfer and found

      no significant evidence to indicate that the Transferee will not continue to

    I,
      [identify the certifying individual], certify that:

     

    1. I
      have
      reviewed this annual report on Form 10-K (the “Annual
      Report”),
      and
      all reports on Form 8-K containing distribution reports (collectively with
      this
      Annual Report, the “Reports”)
      filed
      in respect of periods included in the year covered by this Annual Report, of
      the
      Trust;

     

    2. Based
      on
      my knowledge, the information in the Reports, taken as a whole, does not contain
      any untrue statement of a material fact or omit to state a material fact
      necessary to make the statements made, in light of the circumstances under
      which
      such statements were made, not misleading as of the last day of the period
      covered by this Annual Report;

     

    3. Based
      on
      my knowledge, the distribution or servicing information required to be provided
      to the Trustee by the Servicer under the Trust Agreement, for inclusion in
      the
      Reports is included in the Reports;

     

    4. Based
      on
      my knowledge and upon the annual compliance statement included in this Annual
      Report and required to be delivered to the Trustee in accordance with the terms
      of the Trust Agreement, and except as disclosed in the Reports, the Servicer
      has
      fulfilled its obligations under the Trust Agreement; and

     

    5. The
      Reports disclose all significant deficiencies relating to the Servicer’s
      compliance with the minimum servicing standards based upon the report provided
      by an independent public accountant, after conducting a review in compliance
      with the Uniform Single Attestation Program for Mortgage Bankers or similar
      procedure, as set forth in the Trust Agreement, that is included in the
      Reports.

     

    In
      giving
      the certifications above, I have reasonably relied on information provided
      to me
      by the following unaffiliated parties: the Trustee and the
      Servicer.

      the
      best of my knowledge, and assuming the accuracy of information and statements
      required to be made or delivered by the Servicer, Custodian and the Depositor,
