    This
      Pooling and Servicing Agreement, dated and effective as of January 1, 2006
      (this
“Agreement”), is executed by and among Deutsche Alt-A Securities, Inc., as
      depositor (the “Depositor”), Wells Fargo Bank, National Association, as master
      servicer (the “Master Servicer”) and securities administrator (the “Securities
      Administrator”), and HSBC Bank USA, National Association, as trustee (the
“Trustee”). Capitalized terms used in this Agreement and not otherwise defined
      have the meanings ascribed to such terms in Article I hereof.

     

    PRELIMINARY
      STATEMENT

     

    The
      Depositor at the Closing Date is the owner of the Loans and the other property
      being conveyed by it to the Trustee for inclusion in the Trust Fund. The Trust
      Fund will consist of a segregated pool of assets comprised of the Loans, the
      Subsequent Loans and certain other assets. On the Closing Date, the Depositor
      will acquire the Certificates from the Trust Fund as consideration for its
      transfer to the Trust Fund of the Loans and certain other assets and will be
      the
      owner of the Certificates. The Depositor has duly authorized the execution
      and
      delivery of this Agreement to provide for the conveyance to the Trustee of
      the
      Loans and the issuance to the Depositor of the Certificates representing in
      the
      aggregate the entire beneficial ownership of the Trust Fund. All covenants
      and
      agreements made by the Depositor, the Master Servicer, the Securities
      Administrator and the Trustee herein with respect to the Loans and the other
      property constituting the Trust Fund are for the benefit of the Holders from
      time to time of the Certificates. The Depositor, the Master Servicer, the
      Securities Administrator and the Trustee are entering into this Agreement,
      and
      the Trustee is accepting the trust created hereby, for good and valuable
      consideration, the receipt and sufficiency of which are hereby
      acknowledged.

     

    The
      Certificates issued hereunder, other than the Junior Subordinate Certificates,
      have been offered for sale pursuant to a Prospectus, dated August 26, 2005
      and a
      Prospectus Supplement, dated January 31, 2006 of the Depositor (together, the
      “Prospectus”). The Junior Subordinate Certificates have been offered for sale
      pursuant to a Private Placement Memorandum, dated January 31, 2006. The Trust
      Fund created hereunder is intended to be the “Trust” as described in the
      Prospectus and the Certificates are intended to be the “Certificates” described
      therein.

     

    REMIC
      I

     

    As
      provided herein, the Trustee will make an election to treat the segregated
      pool
      of assets described in the definition of REMIC I (as defined herein), and
      subject to this Agreement, as a real estate mortgage investment conduit (a
      “REMIC”) for federal income tax purposes and such segregated pool of assets will
      be designated as “REMIC I”. The REMIC I Regular Interests will be the “regular
      interests” in REMIC I and Component R-1 of the Class I-R Certificates will
      represent the sole Class of “residual interests” in REMIC I for purposes of the
      REMIC Provisions (as defined herein) under the federal income tax law. The
      following table irrevocably sets forth the designation, the Uncertificated
      REMIC
      I Pass-Through Rate, the initial Uncertificated Principal Balance, and for
      purposes of satisfying Treasury regulation Section 1.860G-1(a)(4)(iii), the
“latest possible maturity date” for each of the REMIC I Regular Interests. None
      of the REMIC I Regular Interests will be certificated.

    REMIC
      II

     

    As
      provided herein, the Trustee will elect to treat the segregated pool of assets
      consisting of the REMIC II Regular Interests as a REMIC for federal income
      tax
      purposes, and such segregated pool of assets will be designated as “REMIC II.”
Component R-2 of the Class I-R Certificates will evidence the sole class of
      “residual interests” in REMIC II for purposes of the REMIC Provisions. The
      following table irrevocably sets forth the designation, the Uncertificated
      REMIC
      II Pass-Through Rate, the initial aggregate Uncertificated Principal Balance
      and, for purposes of satisfying Treasury regulation
      Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for each
      of the REMIC II Regular Interests. None of the REMIC II Regular Interests will
      be certificated.

    ___________________________

    (1) For
      purposes of Section 1.860G-1(a)(4)(iii) of the Treasury regulations, the
      Distribution Date immediately following the maturity date for the Mortgage
      Loan
      with the latest maturity date has been designated as the “latest possible
      maturity date” for each REMIC II Regular Interest.

     

    (2) Calculated
      in accordance with the definition of “Uncertificated REMIC II Pass-Through Rate”
herein.

     

    (3) REMIC
      II
      Regular Interest IO will not have an Uncertificated Principal Balance, but
      will
      accrue interest on its Notional Amount.

     

    

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    REMIC
      III

     

    As
      provided herein, the Trustee will make an election to treat the segregated
      pool
      of assets consisting of the REMIC II Regular Interests as a REMIC for federal
      income tax purposes, and such segregated pool of assets will be designated
      as
“REMIC III”. Component R-3 of the Class I-R Certificates shall represent the
      sole Class of “residual interests” in REMIC III for purposes of the REMIC
      Provisions under federal income tax law. The following table irrevocably sets
      forth the designations, the Initial Pass-Through Rate and initial aggregate
      Certificate Principal Balance for each Class of Group I Certificates which,
      together with Component R-3, constitute the entire beneficial interests in
      REMIC
      III. Determined for purposes of satisfying Treasury regulation
      Section 1.860G-1(a)(4)(iii), the “latest possible maturity date” for each
      Class of Group I Certificates shall be the Distribution Date in the month
      following the maturity date for the Group I Mortgage Loan with the latest
      maturity date:

    Certificate
      Principal Balance:
      The

      amount that the holder of such Certificate is entitled to receive as
      distributions allocable to principal from the cash flow on the Loans in the
      related Loan Group and the other assets in the Trust Fund. The Certificate
      Principal Balance of a Senior Certificate and any Subordinate Certificate,
      as of
      any date of determination is equal to the initial Certificate Principal Balance
      of such Certificate reduced by the aggregate of (i) all amounts allocable to
      principal previously distributed with respect to that Certificate and (ii)
      any
      reductions in the Certificate Principal Balance of such Certificate deemed
      to
      have occurred in connection with allocations of Realized Losses, if any;
      provided that, the Certificate Principal Balance of any Class of Group I Senior
      Certificates and Mezzanine Certificates with the highest payment priority to
      which Realized Losses on the Group I Loans have been allocated shall be
      increased by the amount of any Subsequent Recoveries on the Group I Loans
      received by the related Servicer or the Master Servicer, but not by more than
      the amount of Realized Losses previously allocated to reduce the Certificate
      Principal Balance of that certificate and not previously reimbursed to such
      certificate as an Allocated Realized Loss Amount; provided, further that, the
      Certificate Principal Balance of any Group II-V Senior Certificates or
      Subordinate Certificates with the highest payment priority to which Realized
      Losses on the Group II-V Loans have been allocated shall be increased by the
      amount of any Subsequent Recoveries on the Group II-V Loans received by the
      related Servicer or the Master Servicer, but not by more than the amount of
      Realized Losses previously allocated to reduce the Certificate Principal Balance
      of that Certificate and not previously reimbursed to such Certificate as
      provided in this Agreement. The Certificate Principal Balance of the Class
      I-CE
      Certificate as of any date of determination is equal to the excess, if any,
      of
      (i) the then aggregate principal balance of the Group I Loans over (ii) the
      then
      aggregate Certificate Principal Balance of the Group I Senior Certificates
      and
      the Mezzanine Certificates. The initial Certificate Principal Balance of each
      of
      the Class I-P1 Certificates and the Class I-P2 Certificates is equal to $100.
      The initial Certificate Principal Balance of each Class of Certificates is
      set
      forth in the Preliminary Statement hereto. When used in reference to a Class,
      the term Certificate Principal Balance means the aggregate of the Certificate
      Principal Balances of all Certificates of such Class, and when used in reference
      to a group of Certificates (such as the Group I Senior Certificates and
      Subordinate Certificates) shall mean the aggregate Certificate Principal
      Balances of all Classes of Certificates included in such group.

     

    Certificate
      Register:
      The
      register maintained pursuant to Section 5.2.

     

    Certificateholder
      or Holder:
      The
      person in whose name a Certificate is registered in the Certificate Register,
      except that, solely for the purposes of giving any consent pursuant to this
      Agreement, any Certificate registered in the name of the Depositor, the Master
      Servicer, the Securities Administrator, the Trustee or any Affiliate thereof
      shall be deemed not to be outstanding and the Percentage Interest evidenced
      thereby shall not be taken into account in determining whether the requisite
      percentage of Percentage Interests necessary to effect any such consent has
      been
      obtained. The Trustee or the Securities Administrator may conclusively rely
      upon
      a certificate of the Depositor, the Sponsor or the Master Servicer in
      determining whether a Certificate is held by an Affiliate thereof. All
      references herein to “Holders” or “Certificateholders” shall reflect the rights
      of Certificate Owners as they may indirectly exercise such rights through the
      Depository and participating members thereof, except as otherwise specified
      herein; provided, however, that the Trustee or the Securities Administrator
      shall be required to recognize as a “Holder” or “Certificateholder” only the
      Person in whose name a Certificate is registered in the Certificate
      Register.

      With
      respect to any Distribution Date (i) prior to the Group I Stepdown Date or
      on or
      after the Group I Stepdown Date if a Group I Trigger Event is in effect for
      that
      Distribution Date, the remaining Group I Principal Distribution Amount for
      that
      Distribution Date after distributions to the Supplemental Interest Trust
      pursuant to Section 4.1(b)(i), distribution of the Group I Senior Principal
      Distribution Amount or (ii) on or after the Group I Stepdown Date if a Group
      I

      Group I Senior Principal Distribution Amount on the Distribution Date and (ii)

      during the related Prepayment Period) over the product of (i) 0.50% and (ii)
      the
      aggregate principal balance of the Group I Loans as of the Cut-Off
      Date.

      providing for such investment; provided, however, that securities issued by

      held in the Distribution Account;

      a
      right to receive only interest payments or (ii) the right to receive principal
      and interest payments derived from the underlying investment provides a yield
      to

      one
      month rate which appears on the Dow Jones Telerate System, page 3750, as of

      procedure:

      principal London offices of each of four major Reference Banks in the London
      interbank market, as selected by the Securities Administrator, to provide the
      Securities Administrator with its offered quotation for deposits in United
      States dollars for the upcoming one-month period, commencing on the second
      LIBOR
      Business Day immediately following such LIBOR Determination Date, to prime
      banks

      Determination Date will be the arithmetic mean of such quotations.

     

    (ii)
       If
      fewer
      than two quotations are provided, LIBOR determined on such LIBOR Determination
      Date will be the arithmetic mean of the rates quoted at approximately 11:00
      a.m.
      in New York City on such LIBOR Determination Date by three major banks in New
      York City selected by the Securities Administrator for one-month United States
      dollar loans to lending European banks, in a principal amount that is
      representative for a single transaction in United States dollars in such market
      at such time; provided, however, that if the banks so selected by the Securities
      Administrator are not quoting as mentioned in this sentence, LIBOR determined
      on

      effect on such LIBOR Determination Date.

     

    The
      establishment of LIBOR and each Pass-Through Rate for the Group I Certificates

      cause the Servicers to be reimbursed for any such costs the Servicers may incur
      in connection with performing its obligations under this Agreement.

      2.2 Acceptance
      by Trustee.
      The
      Trustee acknowledges receipt, subject to the provisions of Section 2.1
      hereof and Section 2 of the Custodial Agreements, of the Loan Documents and
      all other assets included in the definition of “REMIC I” and “REMIC A”
under clauses (i), (ii), (to the extent of amounts deposited into the
      Distribution Accounts), (iv) and (v) and declares that it holds (or the related
      Custodian on its behalf holds) and will hold such documents and the other
      documents delivered to it constituting a Loan Document, and that it holds (or
      the related Custodian on its behalf holds) or will hold all such assets and
      such
      other assets included in the definition of “REMIC I” and “REMIC A” in trust
      for the exclusive use and benefit of all present and future
      Certificateholders.

     

    Section
      2.3 Repurchase
      or Substitution of Loans.

     

    (a) Upon
      discovery or receipt of notice of any materially defective document in, or
      that
      a document is missing from, a Mortgage File or of a breach by the Sponsor of
      any
      representation, warranty or covenant under the Mortgage Loan Purchase Agreement
      in respect of any Loan that materially and adversely affects the value of such
      Loan or the interest therein of the Certificateholders, the Trustee or the
      related Custodian shall promptly notify the Sponsor of such defect, missing
      document or breach and request that the Sponsor deliver such missing document,
      cure such defect or breach within 60 days from the date the Sponsor was notified
      of such missing document, defect or breach, and if the Sponsor does not deliver
      such missing document or cure such defect or breach in all material respects
      during such period, the Trustee shall enforce the obligations of the Sponsor
      under the Mortgage Loan Purchase Agreement to repurchase such Loan from REMIC
      I
      or REMIC A at the Purchase Price within 90 days after the date on which the
      Sponsor was notified of such missing document, defect or breach, if and to
      the
      extent that the Sponsor is obligated to do so under the Mortgage Loan Purchase
      Agreement. The Purchase Price for the repurchased Loan shall be deposited in
      the
      Distribution Account and the Trustee, upon receipt of written certification
      from
      the Securities Administrator of such deposit and receipt by the related
      Custodian of a properly completed request for release for such Loan in the
      form
      of Exhibit
      3
      to the
      Custodial Agreements, shall release or cause the related Custodian to release
      to
      the Sponsor the related Mortgage File and the Trustee shall execute and deliver
      such instruments of transfer or assignment, in each case without recourse,
      representation or warranty, as the Sponsor shall furnish to it and as shall
      be
      necessary to vest in the Sponsor any Loan released pursuant hereto, and the
      Trustee shall not have any further responsibility with regard to such Mortgage
      File. In lieu of repurchasing any such Loan as provided above, if so provided
      in
      the Mortgage Loan Purchase Agreement, the Sponsor may cause such Loan to be
      removed from REMIC I or REMIC A (in which case it shall become a Deleted
      Loan) and substitute one or more Substitute Loans in the manner and subject
      to
      the limitations set forth in Section 2.3(b). It is understood and agreed
      that the obligation of the Sponsor to cure or to repurchase (or to substitute
      for) any 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 respecting such omission, defect
      or
      breach available to the Trustee and the Certificateholders. Notwithstanding
      the
      foregoing, if the representation made by the Sponsor in Section 6(xxiv) of
      the Mortgage Loan Purchase Agreement is breached, the Trustee shall enforce
      the
      obligation of the Sponsor to repurchase such Loan at the Purchase Price, or
      to
      provide a Substitute Loan (plus any costs and damages incurred by the Trust
      Fund
      in connection with any violation by any such Loan of any predatory or abusive
      lending law) within 90 days after the date on which the Sponsor was notified
      of
      such breach. 

     

    In
      addition, promptly upon the earlier of discovery by the Master Servicer or
      receipt of notice from a Servicer or the Sponsor to a Responsible Officer of
      the
      Master Servicer of the breach of the representation of the Sponsor set forth
      in
      Section 5(x) of the Mortgage Loan Purchase Agreement which materially and
      adversely affects the interests of the Holders of the Certificates in any
      Prepayment Charge, the Master Servicer shall promptly notify the Sponsor and
      the
      Trustee of such breach. The Trustee shall enforce the obligations of the Sponsor
      under the Mortgage Loan Purchase Agreement to remedy such breach to the extent
      and in the manner set forth in the Mortgage Loan Purchase
      Agreement.

     

    (b) Any
      substitution of Substitute Loans for Deleted Loans made pursuant to
      Section 2.3(a) must be effected prior to the date which is two years after
      the Startup Day for REMIC I.

     

    As
      to any
      Deleted Loan for which the Sponsor, substitutes a Substitute Loan or Loans,
      such
      substitution shall be effected by the Sponsor delivering to the Trustee or
      the
      related Custodian on behalf of the Trustee, for such Substitute Loan or Loans,
      the Mortgage Note, the Mortgage, the Assignment to the Trustee, and such other
      documents and agreements, with all necessary endorsements thereon, as are
      required by Section 2 of the Custodial Agreements, as applicable, together
      with an Officers’ Certificate providing that each such Substitute Loan satisfies
      the definition thereof and specifying the Substitution Shortfall Amount (as
      described below), if any, in connection with such substitution. The related
      Custodian on behalf of the Trustee shall acknowledge receipt of such Substitute
      Loan or Loans and, within ten Business Days thereafter, review such documents
      and deliver to the Depositor, the Trustee and the Master Servicer, with respect
      to such Substitute Loan or Loans, an initial certification pursuant to the
      related Custodial Agreement, with any applicable exceptions noted thereon.
      Within one year of the date of substitution, the related Custodian on behalf
      of
      the Trustee shall deliver to the Depositor, the Trustee and the Master Servicer
      a final certification pursuant to the related Custodial Agreement with respect
      to such Substitute Loan or Loans, with any applicable exceptions noted thereon.
      Monthly Payments due with respect to Substitute Loans in the month of
      substitution are not part of REMIC I or REMIC A and shall be retained by
      the Sponsor. For the month of substitution, distributions to Certificateholders
      shall reflect the Monthly Payment due on such Deleted Loan on or before the
      Due
      Date in the month of substitution, and the Sponsor shall thereafter be entitled
      to retain all amounts subsequently received in respect of such Deleted Loan.
      The
      Depositor shall give or cause to be given written notice to the
      Certificateholders that such substitution has taken place, shall amend the
      Loan
      Schedule to reflect the removal of such Deleted Loan from the terms of this
      Agreement and the substitution of the Substitute Loan or Loans and shall deliver
      a copy of such amended Loan Schedule to the Trustee and the Master Servicer.
      Upon such substitution, such Substitute Loan or Loans shall constitute part
      of
      the Trust Fund and shall be subject in all respects to the terms of this
      Agreement and the Mortgage Loan Purchase Agreement including all applicable
      representations and warranties thereof included herein or in the Mortgage Loan
      Purchase Agreement.

     

    For
      any
      month in which the Sponsor substitutes one or more Substitute Loans for one
      or
      more Deleted Loans, the Master Servicer shall determine the amount (the
“Substitution Shortfall Amount”), if any, by which the aggregate Purchase Price
      of all such Deleted Loans exceeds the aggregate of, as to each such Substitute
      Loan, the Scheduled Principal Balance thereof as of the Due Date in the month
      of
      substitution, together with one month’s interest on such Scheduled Principal
      Balance at the applicable Net Mortgage Rate, plus all outstanding Advances
      and
      Servicing Advances (including Nonrecoverable Advances) related thereto. On
      the
      date of such substitution, the Sponsor shall deliver or cause to be delivered
      to
      the Securities Administrator for deposit in the related Distribution Account
      an
      amount equal to the Substitution Shortfall Amount, if any, and the Trustee
      or
      the related Custodian on behalf of the Trustee, upon receipt of the related
      Substitute Loan or Loans and certification by the Securities Administrator
      of
      such deposit and receipt by the related Custodian of a properly completed
      request for release for such Loan in the form of Exhibit
      3
      to the
      Custodial Agreements, shall release to the Sponsor the related Mortgage File
      or
      Files and the Trustee shall execute and deliver such instruments of transfer
      or
      assignment, in each case without recourse, representation or warranty, as the
      Sponsor shall deliver to it and as shall be necessary to vest therein any
      Deleted Loan released pursuant hereto.

     

    In
      addition, the Sponsor shall obtain at its own expense and deliver to the Trustee
      an Opinion of Counsel to the effect that such substitution will not cause (a)
      any federal tax to be imposed on any REMIC, including without limitation, any
      federal tax imposed on “prohibited transactions” under Section 860F(a)(1)
      of the Code or on “contributions after the startup date” under
      Section 860G(d)(1) of the Code, or (b) any REMIC to fail to qualify as a
      REMIC at any time that any Certificate is outstanding.

     

    (c) Upon
      discovery by the Depositor, the Sponsor, the Master Servicer or the Trustee
      that
      any 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 Sponsor shall repurchase or substitute one or more
      Substitute Loans for the affected Loan within 90 days of the earlier of
      discovery or receipt of such notice with respect to such affected Loan. Such
      repurchase or substitution shall be made by (i) the Sponsor, if the affected
      Loan’s status as a non-qualified mortgage is or results from a breach of any
      representation, warranty or covenant made by the Sponsor under the Mortgage
      Loan
      Purchase Agreement or (ii) the Depositor, if the affected Loan’s status as a
      non-qualified mortgage does not result from a breach of representation or
      warranty. Any such repurchase or substitution shall be made in the same manner
      as set forth in Section 2.3(a). The Trustee shall reconvey to the Sponsor
      or the Depositor the Loan to be released pursuant hereto in the same manner,
      and
      on the same terms and conditions, as it would a Loan repurchased for breach
      of a
      representation or warranty.

     

    (d) Within
      90
      days of the earlier of discovery by the Master Servicer or receipt of notice
      by
      the Master Servicer of the breach of any representation, warranty or covenant
      of
      the Master Servicer set forth in Section 2.5 which materially and adversely
      affects the interests of the related Certificateholders in any Loan or
      Prepayment Charge, the Master Servicer shall cure such breach in all material
      respects.

      Interests and Residual Interests.

      caused the Securities Administrator to execute and authenticate and has

    ADMINISTRATION
      AND SERVICING OF THE LOANS; ACCOUNTS

     

    Section
      3.1 Master
      Servicer.
      The
      Master Servicer shall supervise, monitor and oversee the obligation of the
      Servicers to service and administer their respective Loans in accordance with
      the terms of the applicable Servicing Agreement and shall have full power and
      authority to do any and all things which it may deem necessary or desirable
      in
      connection with such master servicing and administration. In performing its
      obligations hereunder, the Master Servicer shall act in a manner consistent
      with
      Accepted Master Servicing Practices. Furthermore, the Master Servicer shall
      oversee and consult with each Servicer as necessary from time-to-time to carry
      out the Master Servicer’s obligations hereunder, shall receive, review and
      evaluate all reports, information and other data provided to the Master Servicer
      by each Servicer and shall cause each Servicer to perform and observe the
      covenants, obligations and conditions to be performed or observed by such
      Servicer under the applicable Servicing Agreement. The Master Servicer shall
      independently and separately monitor each Servicer’s servicing activities with
      respect to each related Loan, reconcile the results of such monitoring with
      such
      information provided in the previous sentence on a monthly basis and coordinate
      corrective adjustments to the Servicers’ and Master Servicer’s records, and
      based on such reconciled and corrected information, prepare the statements
      specified in Section 4.6 and any other information and statements required
      to be provided by the Master Servicer hereunder. The Master Servicer shall
      reconcile the results of its Loan monitoring with the actual remittances of
      the
      Servicers to the Distribution Account pursuant to the applicable Servicing
      Agreements.

     

    The
      Trustee shall furnish the Servicers and the Master Servicer with any limited
      powers of attorney and other documents in form acceptable to it necessary or
      appropriate to enable the Servicers and the Master Servicer to service or master
      service and administer the related Loans and REO Property. The Trustee shall
      have no responsibility for any action of the Master Servicer or any Servicer
      pursuant to any such limited power of attorney and shall be indemnified by
      the
      Master Servicer or such Servicer for any cost, liability or expense arising
      from
      the misuse thereof by the Master Servicer or such Servicer.

     

    The
      Trustee, the Custodians and the Securities Administrator shall provide access
      to
      the records and documentation in possession of the Trustee, the Custodians
      or
      the Securities Administrator regarding the related Loans and REO Property and
      the servicing thereof to the Certificateholders, the FDIC, and the supervisory
      agents and examiners of the FDIC, such access being afforded only upon
      reasonable prior written request and during normal business hours at the office
      of the Trustee, the Custodians or the Securities Administrator; provided,
      however, that, unless otherwise required by law, none of the Trustee, the
      Custodians or the Securities Administrator shall be required to provide access
      to such records and documentation if the provision thereof would violate the
      legal right to privacy of any Mortgagor. The Trustee, the Custodians and the
      Securities Administrator shall allow representatives of the above entities
      to
      photocopy any of the records and documentation and shall provide equipment
      for
      that purpose at a charge that covers the Trustee’s, a Custodian’s or the
      Securities Administrator’s actual costs.

     

    The
      Trustee shall execute and deliver to the related Servicer or the Master Servicer
      upon request any court pleadings, requests for trustee’s sale or other documents
      necessary or desirable and, in each case, provided to the Trustee by such
      Servicer or Master Servicer to (i) the foreclosure or trustee’s sale with
      respect to a Mortgaged Property; (ii) any legal action brought to obtain
      judgment against any Mortgagor on the Mortgage Note or any other Loan Document;
      (iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any
      other rights or remedies provided by the Mortgage Note or any other Loan
      Document or otherwise available at law or equity.

     

    Section
      3.2 REMIC-Related
      Covenants.
      For as
      long as each REMIC shall exist, the Trustee and the Securities Administrator
      shall treat each REMIC as a REMIC, and the Trustee and the Securities
      Administrator shall comply with any directions of the Sponsor, the related
      Servicer or the Master Servicer to assure such continuing treatment. In
      particular, the Trustee shall not (a) sell or permit the sale of all or any
      portion of the Loans or of any investment of deposits in an Account unless
      such
      sale is as a result of a repurchase of the Loans pursuant to this Agreement
      or
      the Trustee has received an Opinion of Counsel stating that such sale will
      not
      result in an Adverse REMIC Event as defined in Section 10.1(f)
      hereof  prepared at the expense of the Trust Fund; and (b) other than
      with respect to a substitution pursuant to the Mortgage Loan Purchase Agreement,
      the Assignment Agreements or Section 2.3 of this Agreement, as applicable,
      accept any contribution to any REMIC after the Startup Day without receipt
      of an
      Opinion of Counsel stating that such contribution will not result in an Adverse
      REMIC Event as defined in Section 10.1(f) hereof.

     

    Section
      3.3 Monitoring
      of Servicers.
      a) The
      Master Servicer shall be responsible for monitoring the compliance by each
      Servicer with its duties under the related Servicing Agreement. In the review
      of
      each Servicer’s activities, the Master Servicer may rely upon an officer’s
      certificate of any Servicer with regard to such Servicer’s compliance with the
      terms of its Servicing Agreement. In the event that the Master Servicer, in
      its
      judgment, determines that a Servicer should be terminated in accordance with
      its
      Servicing Agreement, or that a notice should be sent pursuant to such Servicing
      Agreement with respect to the occurrence of an event that, unless cured, would
      constitute grounds for such termination, the Master Servicer shall notify the
      Sponsor and the Trustee thereof and the Master Servicer shall issue such notice
      or take such other action as it deems appropriate; provided, however, that
      if
      the defaulting Servicer is Wells Fargo, the Trustee shall issue such notice
      or
      take such action as it deems appropriate.

     

    (b) The
      Master Servicer, for the benefit of the Trustee and the Certificateholders,
      shall enforce the obligations of each Servicer (other than Wells Fargo) under
      the related Servicing Agreement, and shall, in the event that a Servicer fails
      to perform its obligations in accordance with the related Servicing Agreement,
      subject to the preceding paragraph, terminate the rights and obligations of
      such
      Servicer thereunder and act as servicer of the related Loans or to cause the
      Trustee to enter in to a new Servicing Agreement with a successor servicer
      selected by the Master Servicer; provided, however, that if the defaulting
      servicer is Wells Fargo, the Trustee shall terminate the rights and obligations
      of such Servicer and enter into a new servicing agreement with a successor
      servicer selected by it, provided further that, it is understood and
      acknowledged 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 such successor servicer. Such enforcement, including, without
      limitation, the legal prosecution of claims, termination of Servicing Agreements
      and the pursuit of other appropriate remedies, shall be in such form and carried
      out to such an extent and at such time as the Master Servicer or the Trustee,
      if
      applicable, in its good faith business judgment, would require were it the
      owner
      of the related Loans. The Master Servicer or the Trustee, as applicable, shall
      pay the costs of such enforcement at its own expense, provided that the Master
      Servicer or the Trustee, if applicable, shall not be required to prosecute
      or
      defend any legal action except to the extent that the Master Servicer or the
      Trustee, if applicable, shall have received indemnity reasonably acceptable
      to
      it for its costs and expenses in pursuing such action.

     

    (c) To
      the
      extent that the costs and expenses of the Master Servicer or the Trustee, if
      applicable, related to any termination of a Servicer, appointment of a successor
      servicer or the transfer and assumption of servicing by the Master Servicer
      or
      the Trustee, if applicable with respect to any Servicing Agreement (including,
      without limitation, (i) all legal costs and expenses and all due diligence
      costs
      and expenses associated with an evaluation of the potential termination of
      the
      related Servicer as a result of an event of default by such Servicer and (ii)
      all costs and expenses associated with the complete transfer of servicing,
      including all servicing files and all servicing data and the completion,
      correction or manipulation of such servicing data as may be required by the
      successor servicer to correct any errors or insufficiencies in the servicing
      data or otherwise to enable the successor servicer to service the Loans in
      accordance with the related Servicing Agreement) are not fully and timely
      reimbursed by the terminated Servicer, the Master Servicer or the Trustee,
      if
      applicable, shall be entitled to reimbursement of such costs and expenses from
      the Distribution Account.

     

    (d) The
      Master Servicer shall require each Servicer to comply with the remittance
      requirements and other obligations set forth in the related Servicing
      Agreement.

     

    (e) If
      the
      Master Servicer acts as Servicer, it shall not assume liability for the
      representations and warranties of the Servicer, if any, that it
      replaces.

     

    Section
      3.4 Fidelity
      Bond.
      The
      Master Servicer, at its expense, shall maintain in effect a blanket fidelity
      bond and an errors and omissions insurance policy that would meet the
      requirements of Fannie Mae or Freddie Mac, affording coverage with respect
      to
      all directors, officers, employees and other Persons acting on such Master
      Servicer’s behalf, and covering errors and omissions in the performance of the
      Master Servicer’s obligations hereunder. The errors and omissions insurance
      policy and the fidelity bond shall be in such form and amount generally
      acceptable for entities serving as master servicers or trustees. Any such errors
      and omissions policy and fidelity bond may not be cancelable without thirty
      (30)
      days’ prior written notice to the Trustee.

     

    Section
      3.5 Power
      to Act; Procedures.
      The
      Master Servicer shall master service the Loans and shall have full power and
      authority, subject to the REMIC Provisions and the provisions of Article X
      hereof, to do any and all things that it may deem necessary or desirable in
      connection with the master servicing and administration of the Loans, including
      but not limited to the power and authority (i) to execute and deliver, on behalf
      of the Certificateholders and the Trustee, customary consents or waivers and
      other instruments and documents, (ii) to consent to transfers of any Mortgaged
      Property and assumptions of the Mortgage Notes and related Mortgages, (iii)
      to
      collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate
      foreclosure or other conversion of the ownership of the Mortgaged Property
      securing any Loan, in each case, in accordance with the provisions of this
      Agreement and the related Servicing Agreement, as applicable; provided, however,
      that the Master Servicer shall not (and, consistent with its responsibilities
      under Section 3.3, shall not permit any Servicer to) knowingly or
      intentionally take any action, or fail to take (or fail to cause to be taken)
      any action reasonably within its control and the scope of duties more
      specifically set forth herein, that, under the REMIC Provisions, if taken or
      not
      taken, as the case may be, would cause any REMIC to fail to qualify as a REMIC
      or result in the imposition of a tax upon the Trust Fund (including but not
      limited to the tax on prohibited transactions as defined in
      Section 860F(a)(2) of the Code and the tax on contributions to a REMIC set
      forth in Section 860G(d) of the Code) unless the Master Servicer has
      received an Opinion of Counsel (but not at the expense of the Master Servicer)
      to the effect that the contemplated action will not cause any REMIC to fail
      to
      qualify as a REMIC or result in the imposition of a tax upon any REMIC. The
      Trustee shall furnish the Master Servicer, upon written request from a Servicing
      Officer, with any powers of attorney, in form acceptable to the Trustee,
      empowering the Master Servicer or the
      related Servicer
      to execute and deliver instruments of satisfaction or cancellation, or of
      partial or full release or discharge, and to foreclose upon or otherwise
      liquidate Mortgaged Property, and to appeal, prosecute or defend in any court
      action relating to the Loans or the Mortgaged Property, in accordance with
      the
      applicable Servicing Agreement and this Agreement, and the Trustee shall execute
      and deliver such other documents, as the Master Servicer or the related Servicer
      may request, to enable the Master Servicer to master service and administer
      the
      Loans and carry out its duties hereunder, in each case in accordance with
      Accepted Master Servicing Practices (and the Trustee shall have no liability
      for
      the misuse of any such powers of attorney or any other executed documents
      delivered by the Trustee pursuant to this paragraph, by the Master Servicer
      or
      any Servicer and shall be indemnified by the Master Servicer or such Servicer
      for any costs, liabilities or expenses incurred by the Trustee in connection
      with such misuse). If the Master Servicer or the Trustee has been advised that
      it is likely that the laws of the state in which action is to be taken prohibit
      such action if taken in the name of the Trustee or that the Trustee would be
      adversely affected under the “doing business” or tax laws of such state if such
      action is taken in its name, the Master Servicer shall join with the Trustee
      in
      the appointment of a co-trustee pursuant to Section 8.10 hereof. In the
      performance of its duties hereunder, the Master Servicer shall be an independent
      contractor and shall not, except in those instances where it is taking action
      authorized pursuant to this Agreement to be taken by it in the name of the
      Trustee, be deemed to be the agent of the Trustee.

     

    Section
      3.6 Due-on-Sale
      Clauses; Assumption Agreements.
      To the
      extent provided in the applicable Servicing Agreement and to the extent Loans
      contain enforceable due-on-sale clauses, the Master Servicer shall cause the
      Servicers to enforce such clauses in accordance with the applicable Servicing
      Agreement. If applicable law prohibits the enforcement of a due-on-sale clause
      or such clause is otherwise not enforced in accordance with the applicable
      Servicing Agreement, and, as a consequence, a Loan is assumed, the original
      Mortgagor may be released from liability in accordance with the applicable
      Servicing Agreement.

     

    Section
      3.7 Release
      of Mortgage Files.

     

    (a) Upon
      becoming aware of a Payoff with respect to any Loan, or the receipt by any
      Servicer of a notification that payment in full has been escrowed in a manner
      customary for such purposes for payment to Certificateholders on the next
      Distribution Date, the applicable Servicer will (or if the applicable Servicer
      does not, the Master Servicer may), if required under the applicable Servicing
      Agreement, promptly furnish to the related Custodian, on behalf of the Trustee,
      two copies of a request for release substantially in the form attached to the
      related Custodial Agreement, and signed by a Servicing Officer or in a mutually
      agreeable electronic format which will, in lieu of a signature on its face,
      originate from a Servicing Officer (which certification shall include a
      statement to the effect that all amounts received in connection with such
      payment that are required to be deposited in the Protected Account maintained
      by
      the applicable Servicer pursuant to its Servicing Agreement have been or will
      be
      so deposited) and shall request that the related Custodian, on behalf of the
      Trustee, deliver to the applicable Servicer the related Mortgage File. Upon
      receipt of such certification and request, the related Custodian, on behalf
      of
      the Trustee, shall promptly release the related Mortgage File to the applicable
      Servicer and the Trustee and related Custodian shall have no further
      responsibility with regard to such Mortgage File. Upon any such Payoff, each
      Servicer is authorized to give, as agent for the Trustee, as the mortgagee
      under
      the Mortgage that secured the Loan, an instrument of satisfaction (or assignment
      of mortgage without recourse) regarding the Mortgaged Property subject to the
      Mortgage, which instrument of satisfaction or assignment, as the case may be,
      shall be delivered to the Person or Persons entitled thereto against receipt
      therefor of such payment, it being understood and agreed that no expenses
      incurred in connection with such instrument of satisfaction or assignment,
      as
      the case may be, shall be chargeable to the Distribution Account.

     

    (b) From
      time
      to time and as appropriate for the servicing or foreclosure of any Loan and
      in
      accordance with the applicable Servicing Agreement, the Trustee shall execute
      such documents as shall be prepared and furnished to the Trustee by a Servicer
      or the Master Servicer (in form reasonably acceptable to the Trustee) and as
      are
      necessary to the prosecution of any such proceedings. The related Custodian,
      on
      behalf of the Trustee, shall, upon the request of a Servicer or the Master
      Servicer, and delivery to the Custodian, on behalf of the Trustee, of two copies
      of a request for release signed by a Servicing Officer substantially in the
      form
      attached to the related Custodial Agreement (or in a mutually agreeable
      electronic format which will, in lieu of a signature on its face, originate
      from
      a Servicing Officer), release the related Mortgage File held in its possession
      or control to the related Servicer or the Master Servicer, as applicable. Such
      request for release shall obligate such Servicer or the Master Servicer to
      return the Mortgage File to the related Custodian on behalf of the Trustee,
      when
      the need therefor by the related Servicer or the Master Servicer no longer
      exists unless the Loan shall be liquidated, in which case, upon receipt of
      a
      certificate of a Servicing Officer similar to that hereinabove specified, the
      Mortgage File shall be released by the related Custodian, on behalf of the
      Trustee, to such Servicer or the Master Servicer.

     

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

     

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

     

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

     

    Section
      3.9 Standard
      Hazard Insurance and Flood Insurance Policies.

     

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

     

    (b) Pursuant
      to Section 3.23, any amounts collected by the Master Servicer or by any
      Servicer, under any insurance policies (other than amounts to be applied to
      the
      restoration or repair of the property subject to the related Mortgage or
      released to the Mortgagor in accordance with the applicable Servicing Agreement)
      shall be deposited into the Distribution Account, subject to withdrawal pursuant
      to Section 3.24. Any cost incurred by the Master Servicer or any Servicer
      in maintaining any such insurance if the Mortgagor defaults in its obligation
      to
      do so shall be added to the amount owing under the Loan where the terms of
      the
      Loan so permit; provided, however, that the addition of any such cost shall
      not
      be taken into account for purposes of calculating the distributions to be made
      to Certificateholders and shall be recoverable by the Master Servicer or such
      Servicer pursuant to Section 3.24.

     

    Section
      3.10 Presentment
      of Claims and Collection of Proceeds.
      The
      Master Servicer shall (to the extent provided in the applicable Servicing
      Agreement) cause the related Servicer to, prepare and present on behalf of
      the
      Trustee and the related Certificateholders all claims under any insurance
      policies and take such actions (including the negotiation, settlement,
      compromise or enforcement of the insured’s claim) as shall be necessary to
      realize recovery under such policies. Any proceeds disbursed to the Master
      Servicer (or disbursed to a Servicer and remitted to the Master Servicer) in
      respect of such policies, bonds or contracts shall be promptly deposited in
      the
      Distribution Account upon receipt, except that any amounts realized that are
      to
      be applied to the repair or restoration of the related Mortgaged Property as
      a
      condition precedent to the presentation of claims on the related Loan to the
      insurer under any applicable insurance policy need not be so deposited (or
      remitted).

     

    Section
      3.11 Maintenance
      of the Primary Mortgage Insurance Policies.

     

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

     

    (b) The
      Master Servicer agrees to cause each Servicer (to the extent required under
      the
      related Servicing Agreement) to present, on behalf of the Trustee and the
      related Certificateholders, claims to the insurer under any primary mortgage
      insurance policies and, in this regard, to take such reasonable action as shall
      be necessary to permit recovery under any primary mortgage insurance policies
      respecting defaulted Loans. Pursuant to Sections 3.22 and 3.23, any amounts
      collected by the Master Servicer or any Servicer under any primary mortgage
      insurance policies shall be deposited by the related Servicer in its Protected
      Accounts or by the Master Servicer in the related Distribution Account, subject
      to withdrawal pursuant to Section 3.22 or 3.24, as applicable.

     

    Section
      3.12 Trustee
      to Retain Possession of Certain Insurance Policies and Documents.

     

    The
      Trustee or the related Custodian, shall retain possession and custody of the
      originals (to the extent available) of any primary mortgage insurance policies,
      or certificate of insurance if applicable, and any certificates of renewal
      as to
      the foregoing as may be issued from time to time as contemplated by this
      Agreement. Until all amounts distributable in respect of the Certificates have
      been distributed in full and the Master Servicer otherwise has fulfilled its
      obligations under this Agreement, the Trustee or the related Custodian shall
      also retain possession and custody of each Mortgage File in accordance with
      and
      subject to the terms and conditions of this Agreement and the related Custodial
      Agreement. The Master Servicer shall promptly deliver or cause to be delivered
      to the Trustee or the related Custodian, upon the execution or receipt thereof
      the originals of any primary mortgage insurance policies, any certificates
      of
      renewal, and such other documents or instruments that constitute Loan Documents
      that come into the possession of the Master Servicer from time to
      time.

     

    Section
      3.13 Realization
      Upon Defaulted Loans.
      The
      Master Servicer shall cause each Servicer (to the extent required under the
      related Servicing Agreement) to foreclose upon, repossess or otherwise
      comparably convert the ownership of Mortgaged Properties securing such of the
      Loans as come into and continue in default and as to which no satisfactory
      arrangements can be made for collection of delinquent payments, all in
      accordance with the applicable Servicing Agreement.

     

    Section
      3.14 Compensation
      for the Master Servicer.

     

    (a) In
      addition to the Master Servicer’s right to receive its Master Servicing Fee, all

      related Loan, the deed or certificate of sale shall be issued to the Trustee,
      or
      to its nominee, on behalf of the related Certificateholders. The Master Servicer
      shall, to the extent provided in the applicable Servicing Agreement, cause
      the
      applicable Servicer to sell any REO Property as expeditiously as possible and
      in
      accordance with the provisions of this Agreement and the related Servicing
      Agreement, as applicable. Further, the Master Servicer shall, to the extent
      provided in the related Servicing Agreement, cause the applicable Servicer
      to
      sell any REO Property prior to three years after the end of the calendar year
      of
      its acquisition by REMIC I, unless (i) the Trustee and the Securities
      Administrator shall have been supplied with an Opinion of Counsel to the effect
      that the holding by the Trust Fund of such REO Property subsequent to such
      three-year period will not result in the imposition of taxes on “prohibited
      transactions” of any REMIC hereunder as defined in Section 860F of the Code
      or cause any REMIC hereunder to fail to qualify as a REMIC at any time that
      any
      Certificates are outstanding, in which case the Trust Fund may continue to
      hold
      such Mortgaged Property (subject to any conditions contained in such Opinion
      of
      Counsel) or (ii) the applicable Servicer shall have applied for, prior to the
      expiration of such three-year period, an extension of such three-year period
      in
      the manner contemplated by Section 856(e)(3) of the Code, in which case the
      three-year period shall be extended by the applicable extension period. The
      Master Servicer shall cause the applicable Servicer (to the extent provided
      in
      the related Servicing Agreement) to protect and conserve, such REO Property
      in
      the manner and to the extent required by the applicable Servicing Agreement,
      in
      accordance with the REMIC Provisions and in a manner that does not result in
      a
      tax on “net income from foreclosure property” or cause such REO Property to fail
      to qualify as “foreclosure property” within the meaning of
      Section 860G(a)(8) of the Code.

     

    (b) The
      Master Servicer shall, to the extent required by the related Servicing
      Agreement, cause the applicable Servicer to deposit all funds collected and
      received in connection with the operation of any REO Property in the Protected
      Account.

     

    (c) The
      Master Servicer or the related Servicer, as applicable, upon the final
      disposition of any REO Property, shall be entitled to reimbursement for any
      related unreimbursed Advances and other unreimbursed advances as well as any
      unpaid Servicing Fees or Master Servicing Fees from Liquidation Proceeds
      received in connection with the final disposition of such REO Property;
      provided, that any such unreimbursed Advances as well as any unpaid Servicing
      Fees or Master Servicing Fees may be reimbursed or paid, as the case may be,
      prior to final disposition, out of any net rental income or other net amounts
      derived from such REO Property.

     

    (d) To
      the
      extent provided in the related Servicing Agreement, the Liquidation Proceeds
      from the final disposition of the REO Property, net of any payment to the Master
      Servicer or the applicable Servicer as provided above shall be deposited in
      the
      Protected Account on or prior to the Determination Date in the month following
      receipt thereof and be remitted by wire transfer in immediately available funds
      to the Master Servicer for deposit into the Distribution Account on the next

      understood and agreed that, without limiting the generality of the foregoing,
      payments in the nature of late payment charges or assumption, tax service,
      statement account or payoff, substitution, satisfaction, release and other
      like
      fees and charges, need not be credited by the Master Servicer or the related
      Servicer to the related Distribution Account. In the event that the Master
      Servicer shall deposit or cause to be deposited to the Distribution Account
      any
      amount not required to be credited thereto, the Securities Administrator, upon
      receipt of a written request therefor signed by a Servicing Officer of the
      Master Servicer, shall promptly transfer such amount to the Master Servicer,
      any
      provision herein to the contrary notwithstanding.

     

    (c)          
      The
      Distribution Accounts shall constitute a trust accounts of the Trust Fund
      segregated on the books of the Securities Administrator and held by the
      Securities Administrator in trust in its Corporate Trust Office, and the
      Distribution Accounts and the funds deposited therein shall not be subject
      to,
      and shall be protected from, all claims, liens, and encumbrances of any
      creditors or depositors of the Securities Administrator (whether made directly,
      or indirectly through a liquidator or receiver of the Securities Administrator).
      The amount at any time credited to the Distribution Accounts shall be invested
      in the name of the Master Servicer, in such Eligible Investments selected by
      the
      Master Servicer or deposited in demand deposits with such depository
      institutions as selected by the Master Servicer, provided that time deposits
      of
      such depository institutions would be an Eligible Investment. All Eligible
      Investments shall mature or be subject to redemption or withdrawal on or before,
      and shall be held until, the Distribution Date following the date of the
      investment of such funds (the “Investment Withdrawal Distribution Date”) if the
      obligor for such Eligible Investment is the Securities Administrator or, if
      such
      obligor is any other Person, the Business Day preceding such Investment
      Withdrawal Distribution Date. All investment earnings on amounts on deposit
      in
      the Distribution Account from time to time shall be for the account of the
      Master Servicer. The Master Servicer shall be permitted to receive distribution
      of any and all investment earnings from the Distribution Accounts on each
      Distribution Date. If there is any loss on an Eligible Investment or demand
      deposit, the Master Servicer shall deposit such amount in the Distribution
      Account. With respect to each Distribution Account and the funds deposited
      therein, the Securities Administrator shall take such action as may be necessary
      to ensure that the related Certificateholders shall be entitled to the
      priorities afforded to such a trust account (in addition to a claim against
      the
      estate of the Securities Administrator) as provided by 12 U.S.C. § 92a(e), and
      applicable regulations pursuant thereto, if applicable, or any applicable
      comparable state statute applicable to state chartered banking
      corporations.

      Master Servicer shall keep and maintain separate accounting, on a Loan by Loan
      basis, for the purpose of accounting for any reimbursement from the related
      Distribution Account pursuant to subclauses (i) through (vi), inclusive, or
      with
      respect to any such amounts which would have been covered by such subclauses
      had
      the amounts not been retained by the Master Servicer without being deposited
      in
      the related Distribution Account under Section 3.23(b).

     

    (c)           
      On
      each
      Distribution Date, the Securities Administrator shall distribute the Available
      Distribution Amount with respect to each Loan Group to the Holders of the
      related Certificates in accordance with Section 4.1.

     

    Section
      3.25 Group
      I Reserve Fund.

     

    (a) No
      later
      than the Closing Date, the Securities Administrator shall establish and maintain
      a separate segregated trust account titled, “Group I Reserve Fund, Wells Fargo
      Bank, National Association, in trust for the registered holders of Deutsche
      Alt-A Securities, Inc. Mortgage Loan Trust, Series 2006-AR1, Group I Mortgage
      Pass-Through Certificates.” On the Closing Date, the Depositor will deposit, or
      cause to be deposited, into the Group I Reserve Fund $1,000.

     

    (b) On
      each
      Distribution Date, the Securities Administrator will deposit into the Group
      I
      Reserve Fund an amount equal to the sum of the Net WAC Rate Carryover Amounts
      with respect to the Group I Senior Certificates and Mezzanine Certificates
      rather than distributing such amounts to the Class I-CE Certificateholders.
      On
      each Distribution Date, after making the distributions required under
      Section 4.1(c)(i) through (ix), the Securities Administrator will withdraw
      from the Group I Reserve Fund the amounts on deposit therein and distribute
      such
      amounts to the Group I Senior Certificates and Mezzanine Certificates in respect
      of any Net WAC Rate Carryover Amounts due to the Group I Senior Certificates
      and
      Mezzanine Certificates for such Distribution Date.

     

    (c) 
      The
      Group I Reserve Fund constitutes an “outside reserve fund” within the meaning of
      Treasury Regulation § 1.860G-2(h) and is not an asset of any REMIC. For federal
      and state income tax purposes, the Class I-CE Certificateholders will be deemed
      to be the owner of the Group I Reserve Fund. Upon the termination of the Trust
      Fund, or the payment in full of the Group I Certificates, all amounts remaining
      on deposit in the Group I Reserve Fund will be released by the Trust Fund and
      distributed to the Class I-CE Certificateholders or their designees. The Group
      I
      Reserve Fund will be part of the Trust Fund but not part of any REMIC and any
      payments to the Holders of the Group I Senior Certificates and Mezzanine
      Certificates of Net WAC Rate Carryover Amounts, will not be payments with
      respect to a “regular interest” in a REMIC within the meaning of Code
      Section 860(G)(a)(1).

     

    (d) By
      accepting a Class I-CE Certificate, each Class I-CE Certificateholder hereby
      agrees that the Securities Administrator will deposit into the Group I Reserve
      Fund the amounts described above on each Distribution Date rather than
      distributing such amounts to the Class I-CE Certificateholders. By accepting
      a
      Class I-CE Certificate, each Class I-CE Certificateholder further agrees that
      its agreement to such action by the Securities Administrator is given for good
      and valuable consideration, the receipt and sufficiency of which is acknowledged
      by such acceptance.

     

    (e) At
      the
      direction of the Holders of a majority in Percentage Interest in the Class
      I-CE
      Certificates, the Securities Administrator shall direct any depository
      institution maintaining the Group I Reserve Fund to invest the funds in such
      account in one or more Eligible Investments bearing interest or sold at a
      discount, and maturing, unless payable on demand, (i) no later than the
      Business Day immediately preceding the date on which such funds are required
      to
      be withdrawn from such account pursuant to this Agreement, if a Person other
      than the Securities Administrator or an Affiliate manages or advises such
      investment, and (ii) no later than the date on which such funds are required
      to
      be withdrawn from such account pursuant to this Agreement, if the Securities
      Administrator or an Affiliate manages or advises such investment. All income
      and
      gain earned upon such investment shall be deposited into the Group I Reserve
      Fund. In no event shall the Securities Administrator be liable for any
      investments made pursuant to this clause (e). If the Holders of a majority
      in
      Percentage Interest in the Class I-CE Certificates fail to provide investment
      instructions, funds on deposit in the Group I Reserve Fund shall be held
      uninvested by the Securities Administrator without liability for interest or
      compensation.

     

    (f) For
      federal tax return and information reporting, the right of the Holders of the
      Group I Senior Certificates and Mezzanine Certificates to receive payments
      from
      the Group I Reserve Fund in respect of any Net WAC Rate Carryover Amount shall
      be assigned a value of zero.

    Section
      3.27 Prepayment
      Penalty Verification.

     

    On
      or
      prior to each Servicer Remittance Date, each Servicer shall, to the extent
      provided in the respective Servicing Agreement, provide in an electronic format
      acceptable to the Master Servicer the data necessary for the Master Servicer
      to
      perform its verification duties agreed to by the Master Servicer and the
      Depositor. The Master Servicer or a third party reasonably acceptable to the
      Master Servicer and the Depositor (the “Verification Agent”) will perform such
      verification duties and will use its best efforts to issue its findings in
      a
      report (the “Verification Report”) delivered to the Master Servicer and the
      Depositor within ten (10) Business Days following the related Distribution
      Date;
      provided, however, that if the Verification Agent is unable to issue the
      Verification Report within ten (10) Business Days following the Distribution
      Date, the Verification Agent may issue and deliver to the Master Servicer and
      the Depositor the Verification Report upon the completion of its verification
      duties. The Master Servicer shall forward the Verification Report to the
      respective Servicer and shall notify such Servicer if the Master Servicer has
      determined that such Servicer did not deliver the appropriate Prepayment Charges
      to the Master Servicer in accordance with the respective Servicing Agreement.
      Such written notification from the Master Servicer shall include the loan
      number, prepayment penalty code and prepayment penalty amount as calculated
      by
      the Master Servicer or the Verification Agent, as applicable, of each Loan
      for
      which there is a discrepancy. If the respective Servicer agrees with the
      verified amounts, such Servicer shall adjust the immediately succeeding
      Remittance Report and the amount remitted to the Master Servicer with respect
      to
      prepayments accordingly. If the respective Servicer disagrees with the
      determination of the Master Servicer, such Servicer shall, within five (5)
      Business Days of its receipt of the Verification Report, notify the Master
      Servicer of such disagreement and provide the Master Servicer with detailed
      information to support such Servicer’s position. The respective Servicer and the
      Master Servicer shall cooperate to resolve any discrepancy on or prior to the
      immediately succeeding Servicer Remittance Date, and such Servicer will indicate
      the effect of such resolution on the related Remittance Report and shall adjust
      the amount remitted with respect to prepayments on such Servicer Remittance
      Date
      accordingly.

     

    During
      such time as the respective Servicer and the Master Servicer are resolving
      discrepancies with respect to the Prepayment Charges, no payments in respect
      of
      any disputed Prepayment Charges will be remitted to the Distribution Account
      and
      the Master Servicer shall not be obligated to remit such payments, unless
      otherwise required pursuant to Section 7.1 hereof. In connection with such
      duties, the Master Servicer shall be able to rely solely on the information
      provided to it by the respective Servicer in accordance with this Section.
      The
      Master Servicer shall not be responsible for verifying the accuracy of any
      of
      the information provided to it by the respective Servicer or for performing
      the
      Master Servicer’s duties under this Section 3.27 with respect to a Servicer
      if such Servicer is unable or unwilling to provide the required data to the
      Master Servicer or is not required to provide such information to the Master
      Servicer.

      respect to any failure to properly prepare, execute and/or timely file such

      or failure to obtain or receive, on a timely basis, any information from any
      other party hereto needed to prepare, arrange for execution or file such Form
      10-D, not resulting from its own negligence, bad faith or willful

      so under applicable law, the Securities Administrator shall prepare and file
      a
      Form 15 relating to the automatic suspension of reporting in respect of the
      Trust under the Exchange Act. 

     

    (ii) In
      the
      event that the Securities Administrator 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 by this Agreement because required disclosure information was either
      not delivered to it or delivered to it after the delivery deadlines set forth
      in
      this Agreement or for any other reason, the Securities Administrator will
      promptly notify the Depositor. In the case of Form 10-D and 10-K, the parties
      to
      this Agreement will 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 Securities Administrator will, upon receipt of all required Form
      8-K Disclosure Information and upon the approval and direction of the Depositor,
      include such disclosure information on the next Form 10-D. In the event that
      any
      previously filed Form 8-K, 10-D or 10-K needs to be amended and such amendment
      includes any Additional Form 10-D Disclosure, any Additional Form 10-K
      Disclosure or any Form 8-K Disclosure Information or any amendment to such
      disclosure, the Securities Administrator will notify the Depositor of the
      amendment pertaining to an additional reporting item on such form and the
      Depositor will cooperate with the Securities Administrator to prepare any
      necessary 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 Master Servicer
      in
      charge of the master servicing function. The parties to this Agreement
      acknowledge that the performance by the Master Servicer and the Securities
      Administrator of its duties under this Section 3.28(c) related to the timely
      preparation, execution and filing of Form 15, a Form 12b-25 or any amendment
      to
      Form 8-K, 10-D or 10-K is contingent upon each such party performing its duties
      under this Agreement. Neither the Master Servicer nor the Securities
      Administrator shall have any liability for any loss, expense, damage, claim
      arising out of or with respect to any failure to properly prepare, execute
      and/or timely file any such Form 15, Form 12b-25 or any amendments to Forms
      8-K,
      10-D or 10-K, where such failure results from the Securities Administrator’s
      inability or failure to obtain or receive, on a timely basis, any information
      from any other party hereto needed to prepare, arrange for execution or file
      such Form 15, Form 12b-25 or any amendments to Forms 8-K, 10-D or 10-K, not
      resulting from its own negligence, bad faith or willful misconduct.

     

    (d)         
      (i) 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”) (it being
      understood that the fiscal year for the Trust ends on December 31st of each
      year), commencing in March 2007, the Securities Administrator 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 Securities Administrator
      within the applicable time frames set forth in this Agreement, the Servicing
      Agreements and the Custodial Agreements, (i) an annual compliance statement
      for
      the Servicers, each Additional Servicer, the Master Servicer, the Securities
      Administrator and any Servicing Function Participant engaged by such parties
      (together with the Custodians, each, a “Reporting Servicer”) as described under
      the related Servicing Agreement or Custodial Agreement and Section 3.16, (ii)(A)
      the annual reports on assessment of compliance with servicing criteria for
      each
      Reporting Servicer, as described in the related Servicing Agreement and Section
      3.17, and (B) if each Reporting Servicer’s report on assessment of compliance
      with servicing criteria described under the related Servicing Agreement and
      Section 3.17 identifies any material instance of noncompliance, disclosure
      identifying such instance of noncompliance, or if each Reporting Servicer’s
      report on assessment of compliance with servicing criteria described in the
      related Servicing Agreement or Custodial Agreement and Section 3.17 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 each Reporting
      Servicer, as described in the related Servicing Agreement or Custodial Agreement
      or under Section 3.18, and (B) if any registered public accounting firm
      attestation report described in the related Servicing Agreement or Custodial
      Agreement or under Section 3.18 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) the Sarbanes-Oxley
      Certification as described in Section 3.19. 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 determined and prepared by and at
      the direction of the Depositor pursuant to the following paragraph and the
      Securities Administrator will have no duty or liability for any failure
      hereunder to determine or prepare any Additional Form 10-K Disclosure, except
      as
      set forth in the next paragraph.

     

    (ii) As
      set
      forth on Exhibit G hereto, no later than March 15 of each year that the Trust
      is
      subject to the Exchange Act reporting requirements, commencing in 2007, (i)
      the
      parties to the Deutsche Alt-A Securities Mortgage Loan Trust, Series 2006-AR1
      transaction shall be required to provide to the Securities Administrator and
      the
      Depositor, to the extent known by a responsible officer thereof, in
      EDGAR-compatible form, or in such other form as otherwise agreed upon by the
      Securities Administrator and such party, the form and substance of any
      Additional Form 10-K Disclosure, if applicable, together with an Additional
      Disclosure Notification and (ii) the Depositor will approve, as to form and
      substance, or disapprove, as the case may be, the inclusion of the Additional
      Form 10-K Disclosure on Form 10-K. The Depositor will be responsible for any
      reasonable fees and expenses assessed or incurred by the Securities
      Administrator in connection with including any Additional Form 10-K Disclosure
      on Form 10-K pursuant to this paragraph.

     

    (iii) After
      preparing the Form 10-K, the Securities Administrator shall forward
      electronically a draft copy of the Form 10-K to the Master Servicer and, if
      the
      Form 10-K contains Additional Form 10-K Disclosure, the Form 10-K will be sent
      to the Depositor for review and approval prior to execution by the Master
      Servicer. No later than the Business Day prior to the date specified in the
      next
      sentence, the Depositor and the Master Servicer shall notify the Securities
      Administrator of any changes to or approval of such Form 10-K. No later than
      12:00 noon New York time on the 4th
      Business
      Day prior to the 10-K Filing Deadline, an officer of the Master Servicer in
      charge of the master servicing function shall sign the Form 10-K and return
      an
      electronic or fax copy of such signed Form 10-K (with an original executed
      hard
      copy to follow by overnight mail) to the Securities Administrator. If a Form
      10-K cannot be filed on time or if a previously filed Form 10-K needs to be
      amended, the Securities Administrator will follow the procedures set forth
      in
      Section 3.28(c)(ii). Promptly (but no later than 1 Business Day) after filing
      with the Commission, the Securities Administrator will make available on its
      internet website a final executed copy of each Form 10-K that has been prepared
      and filed by the Securities Administrator. The parties to this Agreement
      acknowledge that the performance by the Master Servicer and the Securities
      Administrator of their respective duties under this Section 3.28(d) related
      to
      the timely preparation, execution and filing of Form 10-K is contingent upon
      such parties (and any Additional Servicer or Servicing Function Participant)
      strictly observing all applicable deadlines in the performance of their duties
      under this Section 3.28(d), the related Servicing Agreement, Section 3.17,
      Section 3.18 and Section 3.19. Neither the Master Servicer nor the Securities
      Administrator shall have any liability for any loss, expense, damage, claim
      arising out of or with respect to any failure to properly prepare, execute
      and/or timely file such Form 10-K, where such failure results from the
      Securities Administrator’s inability or failure to obtain or receive, on a
      timely basis, any information from any other party hereto needed to prepare,
      arrange for execution or file such Form 10-K, not resulting from its own
      negligence, bad faith or willful misconduct.

     

    (e)          
      The
      Securities Administrator shall indemnify and hold harmless the Depositor, the
      Trustee and their respective officers, directors 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 a breach of the Securities Administrator’s obligations under
      this Section 3.28 or the Securities Administrator’s negligence, bad faith or
      willful misconduct in connection therewith. 

     

    Notwithstanding
      the provisions of Section 11.1, this Section 3.28 may be amended without the
      consent of the Certificateholders.

      provisions.

      Certificates in the following manner and order of priority: first,
      concurrently to the Group I Senior Certificates, on a pro
      rata
      basis,

      in
      each case on a pro rata basis, based on the Certificate Principal Balance of

      has
      been reduced to zero;

     

    (iii) third,
      from
      the related Available Distribution Amount remaining after payments pursuant
      to
      clauses (i) and (ii) above, to each class of Group II-V Senior Certificates
      for
      which a Senior Interest Shortfall Amount exists, the Senior Interest Shortfall

      clauses (i) through (iii) above, to each class of Group II-V Senior
      Certificates, the amount of any unreimbursed losses previously allocated to
      each
      class; and

     

    (v) fifth,
      to the Class A-R Certificates, the remainder, if any (which is expected to
      be
      zero), of the Group II-V Available Distribution Amount remaining after
      distributions pursuant to clauses (i) through (iv) above.

     

    (q) If
      on any
      Distribution Date there is an Undercollateralized Group, then the following
      will
      occur:

     

    (i) the
      related Group II-V Available Distribution Amount of the Overcollateralized
      Group
      will be reduced, after distributions of interest to the Group III-VII Senior
      Certificates related to such Overcollateralized Group, by an amount equal to
      one
      month’s interest on the Transfer Payment Received by the Undercollateralized
      Group at the weighted average Net Mortgage Rate of the Loans in such
      Undercollateralized Group and that amount will be added to the related Group
      II
      V Available Distribution Amount of the Undercollateralized Group;
      and

     

    (ii) the
      portion of the related Group II-V Available Distribution Amount in respect
      of
      principal on the Loans in the Overcollateralized Group, after distributions
      of
      principal to the Group II V Senior Certificates of the Overcollateralized Group,
      will be distributed, to the extent of the portion of the Available Distribution
      Amount available therefor, to the Group II-V Senior Certificates of the
      Undercollateralized Group until the Certificate Principal Balance of the Group
      II-V Senior Certificates of the Undercollateralized Group equals the aggregate
      Principal Balance of the Loans in the related Group II-V Loan
      Group.

     

    Consequently,
      the Group II-V Subordinate Certificates will not receive any distributions
      of
      principal until each Undercollateralized Group is no longer
      undercollateralized.

     

    All
      or a
      portion of the distributions to the Group II-V Senior Certificates pursuant
      to
      the transfer payment provisions described above may be made on the Distribution
      Date in the month following the month during which such Transfer Payment occurs
      (without any additional distribution of interest or earnings thereon with
      respect to such delay).

     

    (r) On
      each
      Distribution Date, the Securities Administrator will withdraw from the related
      distribution account all Prepayment Charges received on the Group II-V Loans
      during the related Prepayment Period. Any Prepayment Charge collected that
      relates to a Group II-V Loan serviced by GMAC Mortgage Corporation, Residential
      Funding Corporation and GreenPoint Mortgage Funding, Inc. will be distributed
      to
      the holders of the Class II/V-P1 Certificates. Any Prepayment Charge collected
      that relates to a Group II-V Mortgage Loan serviced by IndyMac Bank, F.S.B.
      will
      be distributed to the holders of the Class II/V-P2 Certificates. The payment
      of
      such Prepayment Charges shall not reduce the Certificate Principal Balance
      of
      the Class II/V-P1 Certificates or Class II/V-P2 Certificates. On the
      Distribution Date immediately following the expiration of the latest Prepayment
      Charge term on the Group II-V Loans or any Distribution Date thereafter, the
      Securities Administrator shall make a payment of principal to the Class II/V-P1
      Certificates and Class II/V-P2 Certificates in reduction of the Certificate
      Principal Balances thereof from amounts on deposit in a separate reserve account
      established and maintained by the Securities Administrator for the exclusive
      benefit of the Class II/V-P1 Certificateholders and Class II/V-P2
      Certificateholders.

      of
      such Certificate and of any Certificate issued upon the registration of transfer
      or exchange therefor or in lieu thereof, whether or not such distribution is
      noted on such Certificate. Holders of such Certificates will not be entitled
      to
      any payment in respect of current interest on the amount of such increases
      for
      any Interest Accrual Period preceding the Distribution Date on which such
      increase occurs.

     

    (b) 
      The
      final distribution of principal of each Certificate (and the final distribution
      with respect to the Residual Certificates upon termination of the Trust Fund)
      shall be payable in the manner provided above only upon presentation and
      surrender thereof on or after the Distribution Date therefor at the office
      or

      on the basis of Curtailments, Payoffs and Monthly Payments on the Loans and
      related Insurance Proceeds and Liquidation Proceeds received and expected to

      believes that the entire remaining unpaid aggregate Certificate Principal
      Balance of any Class of Certificates shall become distributable on the next
      Distribution Date, the Securities Administrator shall, no later than the
      Determination Date of the month of such Distribution Date, mail or cause to
      be
      mailed to each Person in whose name a Certificate to be so retired is registered
      at the close of business on the Record Date, to the Underwriter and to each
      Rating Agency a notice to the effect that:

     

    (i) it
      is
      expected that funds sufficient to make such final distribution shall be
      available in the related Distribution Account on such Distribution Date,
      and

     

    (ii) if
      such
      funds are available, (A) such final distribution shall be payable on such
      Distribution Date, but only upon presentation and surrender of such Certificate
      at the office or agency of the Securities Administrator maintained for such
      purpose (the address of which shall be set forth in such notice), and (B) no
      interest shall accrue on such Certificate after such Distribution
      Date.

    Notwithstanding
      any other provision of this Agreement, the Trustee and the Securities
      Administrator shall comply with all federal withholding requirements respecting
      payments to Certificateholders of interest or original issue discount that
      the
      Trustee and the Securities Administrator reasonably believe are applicable
      under
      the Code. The consent of Certificateholders shall not be required for such
      withholding. In the event the Securities Administrator does withhold any amount
      from interest or original issue discount payments or advances thereof to any
      Certificateholder pursuant to federal withholding requirements, the Securities
      Administrator shall indicate the amount withheld to such
      Certificateholders.

    The
      Securities Administrator shall make such statement (and, at its option, any
      additional files containing the same information in an alternative format)
      available each month to the Certificateholders, the Trustee and the Rating
      Agencies via the Securities Administrator’s internet website. The Securities
      Administrator’s internet website shall initially be located at
      http:\\www.ctslink.com and assistance in using the website can be obtained
      by
      calling the Securities Administrator’s customer service desk at 1-301-815-6600.
      Parties that are unable to use the above distribution option are entitled to
      have a paper copy mailed to them via first class mail by calling the customer
      service desk and indicating such. The Securities Administrator shall have the
      right to change the way such statements are distributed in order to make such
      distribution more convenient and/or more accessible to the above parties and
      the
      Securities Administrator shall provide timely and adequate notification to
      all
      above parties regarding any such changes.

     

    In
      the
      case of information furnished pursuant to subclause (i) above, the amounts
      shall
      be expressed as a dollar amount per single Certificate of the relevant
      Class.

     

    Within
      a
      reasonable period of time after the end of each calendar year, the Securities
      Administrator shall furnish to each Person who at any time during the calendar
      year was a Holder of a Regular Interest Certificate a statement containing
      the
      information set forth in subclause (i) above, aggregated for such calendar
      year
      or applicable portion thereof during which such person was a Certificateholder.
      Such obligation of the Securities Administrator shall be deemed to have been
      satisfied to the extent that substantially comparable information shall be
      provided by the Securities Administrator pursuant to any requirements of the
      Code as from time to time are in force.

     

    Within
      a
      reasonable period of time after the end of each calendar year, the Securities
      Administrator shall furnish to each Person who at any time during the calendar
      year was a Holder of a Class R Certificate a statement setting forth the amount,
      if any, actually distributed with respect to the Class R Certificates aggregated
      for such calendar year or applicable portion thereof during which such Person
      was a Certificateholder.

     

    The
      Securities Administrator shall, upon request, furnish to each Certificateholder,
      during the term of this Agreement, such periodic, special, or other reports
      or
      information, whether or not provided for herein, as shall be reasonable with
      respect to the Certificateholder, as applicable, or otherwise with respect
      to
      the purposes of this Agreement, all such reports or information to be provided
      at the expense of the Certificateholder, in accordance with such reasonable
      and
      explicit instructions and directions as the Certificateholder may
      provide.

      Certificates as of such Distribution Date, using a format and media mutually
      acceptable to the Securities Administrator and Bloomberg.

     

    Section
      4.7 Advances.

     

    If
      the
      Monthly Payment on a Loan or a portion thereof is delinquent as of its Due
      Date,
      other than as a result of interest shortfalls due to bankruptcy proceedings
      or
      application of the Relief Act, and the related Servicer fails to make an advance
      of the delinquent amount pursuant to the related Servicing Agreement, the Master
      Servicer shall deposit in the related Distribution Account, from its own funds
      or from amounts on deposit in the related Distribution Account that are held
      for
      future distribution, not later than the Distribution Account Deposit Date
      immediately preceding the related Distribution Date an amount equal to such
      delinquency, net of the Servicing Fee and Master Servicing Fee for such Loan
      except to the extent the Master Servicer determines any such advance to be
      nonrecoverable from Liquidation Proceeds, Insurance Proceeds, or future payments
      on the Loan for which such Advance was made. Any amounts held for future
      distribution and so used shall be appropriately reflected in the Master
      Servicer’s records and replaced by the Master Servicer by deposit in the related
      Distribution Account on or before any future Distribution Account Deposit Date
      to the extent that related Available Distribution Amount (determined without
      regard to Advances to be made on the related Distribution Account Deposit Date)
      shall be less than the total amount that would be distributed to the related
      Classes of Certificateholders pursuant to Section 4.1 on such Distribution
      Date if such amounts held for future distributions had not been so used to
      make
      Advances. Subject to the foregoing, the Master Servicer shall continue to make
      such Advances through the date that the related Servicer is required to do
      so
      under its Servicing Agreement. In the event the Master Servicer elects not
      to
      make an Advance because the Master Servicer deems such Advance nonrecoverable
      pursuant to this Section 4.7 on the related Distribution Account Deposit
      Date, the Master Servicer shall present an Officer’s Certificate to the Trustee
      (i) stating that the Master Servicer elects not to make an Advance in a stated
      amount and (ii) detailing the reason it deems the advance to be
      nonrecoverable.

     

    Section
      4.8 Supplemental
      Interest Trust.

     

    (a) On
      the
      Closing Date, the Securities Administrator shall establish and maintain in
      the
      name of the Trustee a separate account for the benefit of the Holders of the
      Group I Senior Certificates, Mezzanine Certificates and Class I-CE Certificates
      (the “Supplemental Interest Trust”). The Supplemental Interest Trust shall be an
      Eligible Account, and funds on deposit therein shall be held separate and apart
      from, and shall not be commingled with, any other monies, including, without
      limitation, other monies of the Trustee or of the Securities Administrator
      held
      pursuant to this Agreement. 

     

    (b) On
      each
      Distribution Date, the Securities Administrator shall withdraw all amounts
      which
      were deposited in the Supplemental Interest Trust as specifically described
      in
      this Agreement and the Group I Swap Agreement and distribute such amounts in
      accordance with the provisions of Section 4.1 of this
      Agreement.

     

    (c) The
      Supplemental Interest Trust constitutes an “outside reserve fund” within the
      meaning of Treasury Regulation § 1.860G-2(h) and is not an asset of any REMIC.
      The Holders of the Class I-CE Certificates shall be the beneficial owner of
      the
      Supplemental Interest Trust, subject to the power of the Securities
      Administrator to transfer amounts under this Agreement. The Securities
      Administrator shall keep records that accurately reflect the funds on deposit
      in
      the Supplemental Interest Trust. The Securities Administrator shall, at the
      written direction of the majority of the Class I-CE Certificateholders, invest
      amounts on deposit in the Supplemental Interest Trust in Eligible Investments.
      In the absence of written direction to the Securities Administrator from the
      majority of the Class I-CE Certificateholders, all funds in the Supplemental
      Interest Trust shall remain uninvested. On each Distribution Date, the
      Securities Administrator shall distribute, not in respect of any REMIC, any
      interest earned on the Supplemental Interest Trust in the prior month to the
      Holders of the Class I-CE Certificates.

     

    (d) For
      federal income tax purposes, amounts paid to the Supplemental Interest Trust
      on
      each Distribution Date pursuant to Section 4.1(a)(i), 4.1(b)(i) and
      4.1(d)(vi) shall first be deemed paid to the Supplemental Interest Trust in
      respect of the Class IO Interest to the extent of the amount distributable
      on
      such Class IO Interest on such Distribution Date, and any remaining amount
      shall
      be deemed paid to the Supplemental Interest Trust in respect of a Class IO
      Distribution Amount. For federal income tax purposes, the Supplemental Interest
      Trust will be a disregarded entity.

     

    (e) The
      Securities Administrator shall treat the Holders of the Group I Senior
      Certificates and Mezzanine Certificates as having entered into a notional
      principal contract with respect to the Holders of the Class I-CE Certificates.
      Pursuant to each such notional principal contract, all Holders of the Group
      I
      Senior Certificates and Mezzanine Certificates shall be treated as having agreed
      to pay, on each Distribution Date, to the Holder of the Class I-CE Certificates
      an aggregate amount equal to the excess, if any, of (i) the amount payable
      on
      such Distribution Date on the Regular Interest ownership of which is represented
      by such Class of Certificates over (ii) the amount payable on such Class of
      Certificates on such Distribution Date (such excess, a “Class IO Distribution
      Amount”). A Class IO Distribution Amount payable from interest collections shall
      be allocated pro rata among such Certificates based on the amount of interest
      otherwise payable to such Certificates, and a Class IO Distribution Amount
      payable from principal collections shall be allocated to the most subordinate
      Class of such Certificates with an outstanding principal balance to the extent
      of such balance. In addition, pursuant to such notional principal contract,
      the
      Holder of the Class I-CE Certificates shall be treated as having agreed to
      pay
      Net WAC Rate Carryover Amounts to the Holders of the Group I Senior Certificates
      and Mezzanine Certificates in accordance with the terms of this Agreement.
      Any
      payments to such Certificates from amounts deemed received in respect of this
      notional principal contract shall not be payments with respect to a Regular
      Interest in a REMIC within the meaning of Code Section 860G(a)(1). However,
      any payment from the Group I Senior Certificates and Mezzanine Certificates
      of a
      Class IO Distribution Amount shall be treated for tax purposes as having been
      received by the Holders of such Certificates in respect of the Regular Interest
      ownership of which is represented by such Certificates, and as having been
      paid
      by such Holders to the Supplemental Interest Trust pursuant to the notional
      principal contract. Thus, each Group I Senior Certificates, Mezzanine
      Certificates and Class I-CE Certificates shall be treated as representing not
      only ownership of a Regular Interest in REMIC III, but also ownership of an
      interest in, and obligations with respect to, a notional principal
      contract.

     

    (f) For
      federal tax return and information reporting, the right of the holders of the
      Group I Senior Certificates, Mezzanine Certificates and Class I-CE Certificates
      to receive payments from the Supplemental Interest Trust shall be assigned
      a
      value of $5,000.

     

    (g) In
      the
      event that the Group I Swap Agreement is terminated prior to the Distribution
      Date in November 2011, the Trustee on behalf of the Supplemental Interest Trust,
      at the direction of the Depositor, shall use reasonable efforts to appoint
      a
      successor swap provider using any Group I Swap Termination Payments paid by
      the
      Group I Swap Provider. To the extent the Supplemental Interest Trust is required
      to pay a Group I Swap Termination Payment to the Group I Swap Provider, all
      or a
      portion of such amount received from a replacement swap provider upon entering
      into a replacement interest rate swap agreement or similar agreement will be
      applied to the Group I Swap Termination Payment owing to the Group I Swap
      Provider. If the Trustee on behalf of the Supplemental Interest Trust is unable
      to locate a qualified successor swap provider, any such Group I Swap Termination
      Payments will be deposited in the Supplemental Interest Trust and the Securities
      Administrator, on each subsequent Distribution Date (until the termination
      date
      of the Group I Swap Agreement or the appointment of a successor swap provider),
      will withdraw the amount of any Group I Net Swap Payment due to the Supplemental
      Interest Trust (calculated in accordance with the terms of the Group I Swap
      Agreement) and distribute such Group I Net Swap Payment to the holders of the
      Group I Certificates in accordance with Section 4.1.

     

    Section
      4.9 Tax
      Treatment of Group I Swap Payments and Group I Swap Termination
      Payments.

     

    For
      federal income tax purposes, each holder of a Group I Certificate is deemed
      to
      own an undivided beneficial ownership interest in a REMIC regular interest
      and
      the right to receive payments from either the Group I Reserve Fund or the
      Supplemental Interest Trust in respect of any Net WAC Rate Carryover Amounts
      or
      the obligation to make payments to the Supplemental Interest Trust. For federal
      income tax purposes, the Securities Administrator will account for payments
      to
      each Group I Certificate as follows: each Group I Certificate will be treated
      as
      receiving their entire payment from REMIC III (regardless of any Group I Swap
      Termination Payment or obligation under the Group I Swap Agreement) and
      subsequently paying their portion of any Group I Swap Termination Payment in
      respect of each such Class’s obligation under the Group I Swap Agreement. In the
      event that any such Class is resecuritized in a REMIC, the obligation under
      the
      Group I Swap Agreement to pay any such Group I Swap Termination Payment (or
      any
      shortfall in Group I Net Swap Payment), will be made by one or more of the
      REMIC
      Regular Interests issued by the resecuritization REMIC subsequent to such REMIC
      Regular Interest receiving its full payment from any such Group I Certificate.
      Resecuritization of any Group I Certificate in a REMIC will be permissible
      only
      if the Securities Administrator hereunder is the trustee/securities
      administrator in such resecuritization.

     

    The
      REMIC
      Regular Interest corresponding to an Group I Certificate will be entitled to
      receive interest and principal payments at the times and in the amounts equal
      to
      those made on the certificate to which it corresponds, except that (i) the
      maximum interest rate of that REMIC regular interest will equal the Net WAC
      Pass-Through Rate computed for this purpose by limiting the Group I Swap
      Notional Amount of the Group I Swap Agreement to the aggregate Scheduled
      Principal Balance of the Loans and (ii) any Group I Swap Termination Payment
      will be treated as being payable solely from amounts otherwise payable to the
      Class I-CE Certificates. As a result of the foregoing, the amount of
      distributions and taxable income on the REMIC Regular Interest corresponding
      to
      a Group I Certificate may exceed the actual amount of distributions on the
      Group
      I Certificate.

    THE
      CERTIFICATES

     

    Section
      5.1 The
      Certificates.

     

    (a) The
      Certificates in the aggregate will represent the entire beneficial ownership
      interest in the Loans and all other assets included in REMIC I or
      REMIC A.

     

    The
      Certificates will be substantially in the forms annexed hereto as Exhibits
      A-1
      through A-8. The Certificates of each Class will be issuable in registered
      form
      only, in denominations of authorized Percentage Interests as described in the
      definition thereof. Each Certificate will share ratably in all rights of the
      related Class.

     

    Upon
      original issue, the Certificates shall be executed and authenticated by the
      Securities Administrator and delivered by the Trustee to and upon the written
      order of the Depositor. The Certificates shall be executed by manual or
      facsimile signature on behalf of the Trust by the Securities Administrator
      by an
      authorized signatory. Certificates bearing the manual or facsimile signatures
      of
      individuals who were at any time the proper officers of the Securities
      Administrator shall bind the Trust, notwithstanding that such individuals or
      any
      of them have ceased to hold such offices prior to the authentication and
      delivery of such Certificates or did not hold such offices at the date of such
      Certificates. 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 herein
      executed by the Securities Administrator by manual signature, and such
      certificate of authentication 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.

     

    (b) The
      Certificates, other than the Class R, Class P and Junior Subordinate
      Certificates, shall initially be issued as one or more Certificates held by
      the
      Book-Entry Custodian or, if appointed to hold such Certificates as provided
      below, the Depository and registered in the name of the Depository or its
      nominee and, except as provided below, registration of such Certificates may
      not
      be transferred by the Securities Administrator except to another Depository
      that
      agrees to hold such Certificates for the respective Certificate Owners with
      Ownership Interests therein. The Certificate Owners shall hold their respective
      Ownership Interests in and to such Certificates through the book-entry
      facilities of the Depository and, except as provided below, shall not be
      entitled to definitive, fully registered Certificates (“Definitive
      Certificates”) in respect of such Ownership Interests. All transfers by
      Certificate Owners of their respective Ownership Interests in the Book-Entry
      Certificates shall be made in accordance with the procedures established by
      the
      Depository Participant or brokerage firm representing such Certificate Owner.
      Each Depository Participant shall only transfer the Ownership Interests in
      the
      Book-Entry Certificates of Certificate Owners it represents or of brokerage
      firms for which it acts as agent in accordance with the Depository’s normal
      procedures. The Securities Administrator is hereby initially appointed as the
      Book-Entry Custodian and hereby agrees to act as such in accordance herewith
      and
      in accordance with the agreement that it has with the Depository authorizing
      it
      to act as such. The Book-Entry Custodian may, and, if it is no longer qualified
      to act as such, the Book-Entry Custodian shall, appoint, by a written instrument
      delivered to the Depositor, the Servicers, the Master Servicer and, if the
      Trustee is not the Book-Entry Custodian, the Trustee, any other transfer agent
      (including the Depository or any successor Depository) to act as Book-Entry
      Custodian under such conditions as the predecessor Book-Entry Custodian and
      the
      Depository or any successor Depository may prescribe, provided that the
      predecessor Book-Entry Custodian shall not be relieved of any of its duties
      or
      responsibilities by reason of any such appointment of other than the Depository.
      If the Securities Administrator resigns or is removed in accordance with the
      terms hereof, the successor Securities Administrator or, if it so elects, the
      Depository shall immediately succeed to its predecessor’s duties as Book-Entry
      Custodian. The Depositor shall have the right to inspect, and to obtain copies
      of, any Certificates held as Book-Entry Certificates by the Book-Entry
      Custodian.

     

    (c) Any
      Junior Subordinate Certificate or Class P Certificate initially offered and
      sold
      in offshore transactions in reliance on Regulation S shall be issued in the
      form
      of a temporary global certificate in definitive, fully registered form (each,
      a
“Regulation S Temporary Global Certificate”), which shall be deposited with the
      Securities Administrator or an agent of the Securities Administrator as
      custodian for the Depository and registered in the name of Cede & Co. as
      nominee of the Depository for the account of designated agents holding on behalf
      of Euroclear or Clearstream. Beneficial interests in each Regulation S Temporary
      Global Certificate may be held only through Euroclear or Clearstream; provided,
      however, that such interests may be exchanged for interests in a Definitive
      Certificate in accordance with the requirements described in Section 5.2.
      After the expiration of the Release Date, a beneficial interest in a Regulation
      S Temporary Global Certificate may be exchanged for a beneficial interest in
      the
      related permanent global certificate of the same Class (each, a “Regulation S
      Permanent Global Certificate”), in accordance with the procedures set forth in
      Section 5.2. Each Regulation S Permanent Global Certificate shall be
      deposited with the Securities Administrator or an agent of the Securities
      Administrator as custodian for the Depository and registered in the name of
      Cede
& Co. as nominee of the Depository.

     

    (d) The
      Junior Subordinate Certificates and Class P Certificates offered and sold to
      Qualified Institutional Buyers (“QIBs”) in reliance on Rule 144A under the
      Securities Act (“Rule 144A”) will be issued in the form of Definitive
      Certificates.

     

    (e) The
      Trustee, the Servicers, the Securities Administrator, the Master Servicer and
      the Depositor may for all purposes (including the making of payments due on
      the
      Book-Entry Certificates and Global Certificates) deal with the Depository as
      the
      authorized representative of the Certificate Owners with respect to the
      Book-Entry Certificates and Global Certificates for the purposes of exercising
      the rights of Certificateholders hereunder. The rights of Certificate Owners
      with respect to the Book-Entry Certificates and Global Certificates shall be
      limited to those established by law and agreements between such Certificate
      Owners and the Depository Participants and brokerage firms representing such
      Certificate Owners. Multiple requests and directions from, and votes of, the
      Depository as Holder of the Book-Entry Certificates and Global Certificates
      with
      respect to any particular matter shall not be deemed inconsistent if they are
      made with respect to different Certificate Owners. The Securities Administrator
      may establish a reasonable record date in connection with solicitations of
      consents from or voting by Certificateholders and shall give notice to the
      Depository of such record date.

     

    If
      (i)(A)
      the Depositor advises the Securities Administrator in writing that the
      Depository is no longer willing or able to properly discharge its
      responsibilities as Depository, and (B) the Depositor is unable to locate a
      qualified successor, (ii) the Depositor at its option advises the Securities
      Administrator in writing that it elects to terminate the book-entry system
      through the Depository or (iii) after the occurrence of a Master Servicer Event
      of Default, Certificate Owners representing in the aggregate not less than
      51%
      of the Ownership Interests of the Book-Entry Certificates advise the Securities
      Administrator through the Depository, in writing, that the continuation of
      a
      book-entry system through the Depository is no longer in the best interests
      of
      the Certificate Owners, the Securities Administrator shall notify all
      Certificate Owners, through the Depository, of the occurrence of any such event
      and of the availability of Definitive Certificates to Certificate Owners
      requesting the same. With respect to a Global Certificate, the related
      Certificate Owner (other than a Holder of a Regulation S Temporary Global
      Certificate) may request that its interest in a Global Certificate be exchanged
      for a Definitive Certificate. Upon surrender to the Securities Administrator
      of
      the Book-Entry Certificates by the Book-Entry Custodian or the Depository,
      as
      applicable, or the Global Certificates by the Depository accompanied by
      registration instructions from the Depository for registration of transfer,
      the
      Securities Administrator shall cause the Definitive Certificates to be issued.
      Such Definitive Certificates will be issued in minimum denominations of $10,000
      except that any beneficial ownership that was represented by a Book-Entry
      Certificate, or a Global Certificate, as applicable in an amount less than
      $10,000 immediately prior to the issuance of a Definitive Certificate shall
      be
      issued in a minimum denomination equal to the amount represented by such
      Book-Entry Certificate or a Global Certificate, as applicable. None of the
      Depositor, the Servicers, the Master Servicer, the Securities Administrator
      or
      the Trustee shall be liable for any delay in the 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 Depository shall be deemed
      to be imposed upon and performed by the Securities Administrator on behalf
      of
      the Trustee, to the extent applicable with respect to such Definitive
      Certificates, and the Securities Administrator on behalf of the Trustee shall
      recognize the Holders of the Definitive Certificates as Certificateholders
      hereunder.

     

    (f) Neither
      the Trustee nor the Securities Administrator shall have any liability to the
      Trust Fund and shall be indemnified by the Trust Fund for, any cost, liability
      or expense incurred by them arising from a registration of a Certificate or
      transfer, pledge sale or other disposition of a Certificate in reliance upon
      a
      certification, Officer’s Certificate, affidavit, ruling or Opinion of Counsel
      described in this Article V.

     

    Section
      5.2 Registration
      of Transfer and Exchange of Certificates.

     

    (a) The
      Securities Administrator shall cause to be kept at one of the offices or
      agencies to be appointed by the Securities Administrator in accordance with
      the
      provisions of Section 8.11, a Certificate Register for the Certificates in
      which, subject to such reasonable regulations as it may prescribe, the
      Securities Administrator shall provide for the registration of Certificates
      and
      of transfers and exchanges of Certificates as herein provided.

     

    (b) No
      transfer of any Junior Subordinate Certificate or Class P Certificate shall
      be
      made unless that transfer is made pursuant to an effective registration
      statement under the Securities Act, and effective registration or qualification
      under applicable state securities laws, or is made in a transaction that does
      not require such registration or qualification. In the event that such a
      transfer of a Junior Subordinate Certificate or Class P Certificate is to be
      made without registration or qualification (other than in connection with the
      initial transfer of any such Certificate by the Depositor), the Securities
      Administrator shall require receipt of: (i) if such transfer is purportedly
      being made in reliance upon Rule 144A under the Securities Act, written
      certifications from the Certificateholder desiring to effect the transfer and
      from such Certificateholder’s prospective transferee, substantially in the form
      attached hereto as Exhibit B-1; (ii) if such transfer is purportedly being
      made
      in reliance upon Rule 501(a) under the Securities Act, written certifications
      from the Certificateholder desiring to effect the transfer and from such
      Certificateholder’s prospective transferee, substantially in the form attached
      hereto as Exhibit B-2; (iii) if such transfer is purportedly being made in
      reliance on Regulation S, a written certification from the prospective
      transferee, substantially in the form attached hereto as Exhibit B-3 and (iv)
      in
      all other cases, an Opinion of Counsel satisfactory to the Securities
      Administrator that such transfer may be made without such registration or
      qualification (which Opinion of Counsel shall not be an expense of the Trust
      Fund or of the Depositor, the Trustee, the Master Servicer, the Securities
      Administrator or the Servicers), together with copies of the written
      certification(s) of the Certificateholder desiring to effect the transfer and/or
      such Certificateholder’s prospective transferee upon which such Opinion of
      Counsel is based, if any. Neither of the Depositor nor the Securities
      Administrator is obligated to register or qualify any such Certificates under
      the Securities Act or any other securities laws or to take any action not
      otherwise required under this Agreement to permit the transfer of such
      Certificates without registration or qualification. Any Certificateholder
      desiring to effect the transfer of any such Certificate shall, and does hereby
      agree to, indemnify the Trustee, the Depositor, the Master Servicer, the
      Securities Administrator and the Servicers against any liability that may result
      if the transfer is not so exempt or is not made in accordance with such federal
      and state laws.

     

    A
      holder
      of a beneficial interest in a Regulation S Temporary Global Certificate must
      provide Euroclear or Clearstream, as the case may be, with a certificate in
      the
      form of Annex A to Exhibit B-4 hereto certifying that the beneficial owner
      of
      the interest in such Global Certificate is not a U.S. Person (as defined in
      Regulation S), and Euroclear or Clearstream, as the case may be, must provide
      to
      the Trustee and Securities Administrator a certificate in the form of Exhibit
      B-4 hereto prior to (i) the payment of interest or principal with respect to
      such holder’s beneficial interest in the Regulation S Temporary Global
      Certificate and (ii) any exchange of such beneficial interest for a beneficial
      interest in a Regulation S Permanent Global Certificate.

     

    (c) No
      transfer of a Residual Certificate or Class P Certificate or any interest
      therein shall be made to any Plan subject to ERISA or Section 4975 of the
      Code, any Person acting, directly or indirectly, on behalf of any such Plan
      or
      any Person acquiring such Certificates with “Plan Assets” of a Plan within the
      meaning of the Department of Labor regulation promulgated at 29 C.F.R. §
2510.3-101 (“Plan Assets”) unless the Securities Administrator is provided with
      an Opinion of Counsel on which the Depositor, the Master Servicer, the
      Securities Administrator, the Trustee and the Servicers may rely, which
      establishes to the satisfaction of the Securities Administrator that the
      purchase of such Certificates is permissible under applicable law, will not
      constitute or result in any prohibited transaction under ERISA or
      Section 4975 of the Code and will not subject the Depositor, the Servicers,
      the Trustee, the Master Servicer, the Securities Administrator or the Trust
      Fund
      to any obligation or liability (including obligations or liabilities under
      ERISA
      or Section 4975 of the Code) in addition to those undertaken in this
      Agreement, which Opinion of Counsel shall not be an expense of the Depositor,
      the Servicers, the Trustee, the Master Servicer, the Securities Administrator,
      the Trust Fund. An Opinion of Counsel will not be required in connection with
      the initial transfer of any such Certificate by the Depositor to an affiliate
      of
      the Depositor (in which case, the Depositor or any affiliate thereof shall
      have
      deemed to have represented that such affiliate is not a Plan or a Person
      investing Plan Assets) and the Securities Administrator shall be entitled to
      conclusively rely upon a representation (which, upon the request of the
      Securities Administrator, shall be a written representation) from the Depositor
      of the status of such transferee as an affiliate of the Depositor.

     

    For
      so
      long as the Supplemental Interest Trust is in existence, each beneficial owner
      of a Class A, Mezzanine or Class B Certificate or any interest therein, shall
      be
      deemed to have represented, by virtue of its acquisition or holding of such
      Certificate, or interest therein, that either (i) it is not a Plan or (ii)(A)
      it
      is an accredited investor within the meaning of Prohibited Transaction Exemption
      2002-41, as amended from time to time (the “Exemption”) and (B) the acquisition
      and holding of such Certificate and the separate right to receive payments
      from
      the Supplemental Interest Trust are eligible for the exemptive relief available
      under Prohibited Transaction Class Exemption (“PTCE”) 84-14 (for transactions by
      independent “qualified professional asset managers”), 91-38 (for transactions by
      bank collective investment funds), 90-1 (for transactions by insurance company
      pooled separate accounts), 95-60 (for transactions by insurance company general
      accounts) or 96-23 (for transactions effected by “in-house asset managers”) in
      the case of an Offered Certificate, or PTCE 95-60 in the case of a Junior
      Subordinate Certificate.

     

    Each
      Transferee of a Mezzanine Certificate, Class B Certificate or any interest
      therein that is acquired after the termination of the Supplemental Interest
      Trust will be deemed to have represented by virtue of its purchase or holding
      of
      such Certificate (or interest therein) or with respect to each Transferee of
      a
      Junior Subordinate Certificate, shall certify that either (a) such Transferee
      is
      not a Plan or purchasing such Certificate with Plan Assets, (b) for Certificates
      other than Junior Subordinate Certificates, it has acquired and is holding
      such
      Certificate in reliance on Prohibited Transaction Exemption (“PTE”) 94-84 or FAN
      97-03E, as amended by PTE 97-34, 62 Fed. Reg. 39021 (July 21, 1997), PTE
      2000-58, 65 Fed. Reg. 67765 (November 13, 2000) and PTE 2002-41, 67 Fed. Reg.
      54487 (August 22, 2002) (the “Exemption”), and that it understands that there
      are certain conditions to the availability of the Exemption including that
      such
      Certificate must be rated, at the time of purchase, not lower than “BBB-” (or
      its equivalent) by a Rating Agency or (c) the following conditions are
      satisfied: (i) such Transferee is an insurance company, (ii) the source of
      funds
      used to purchase or hold such Certificate (or interest therein) is an “insurance
      company general account” (as defined in PTCE 95-60, and (iii) the conditions set
      forth in Sections I and III of PTCE 95-60 have been satisfied.

     

    If
      any
      Certificate or any interest therein is acquired or held in violation of the
      conditions described in this Section 5.2(c), the next preceding permitted
      beneficial owner will be treated as the beneficial owner of that Certificate,
      retroactive to the date of transfer to the purported beneficial owner. Any
      purported beneficial owner whose acquisition or holding of any certificate
      or
      interest therein was effected in violation of the conditions described in this
      Section 5.2(c) shall indemnify and hold harmless the Depositor, the
      Trustee, the Servicers, the Master Servicer, the Securities Administrator and
      the Trust Fund from and against any and all liabilities, claims, costs or
      expenses incurred by those parties as a result of that acquisition or
      holding.

     

    (d) Each
      Transferee of a Class R Certificate shall be deemed by the acceptance or
      acquisition of the related Ownership Interest to have agreed to be bound by
      the
      following provisions and to have irrevocably appointed the Depositor or its
      designee as its attorney-in-fact to negotiate the terms of any mandatory sale
      under clause (v) below and to execute all instruments of transfer and to do
      all
      other things necessary in connection with any such sale, and the rights of
      each
      Transferee of a Class R Certificate are expressly subject to the following
      provisions:

     

    (i) Each
      such
      Transferee shall be a Permitted Transferee and shall promptly notify the
      Securities Administrator of any change or impending change in its status as
      a
      Permitted Transferee.

     

    (ii) No
      Person
      shall acquire an Ownership Interest in a Class R Certificate unless such
      Ownership Interest is a pro
      rata
      undivided interest.

     

    (iii) In
      connection with any proposed transfer of any Ownership Interest in a Class
      R
      Certificate, the Securities Administrator shall as a condition to registration
      of the transfer, require delivery to it, in form and substance satisfactory
      to
      it, of each of the following:

     

    (A)
       an
      affidavit in the form of Exhibit C hereto from the proposed Transferee to the
      effect that such Transferee is a Permitted Transferee and that it is not
      acquiring its Ownership Interest in the Class R Certificate that is the subject
      of the proposed transfer as a nominee, trustee or agent for any Person who
      is
      not a Permitted Transferee; and

     

    (B)
       a
      covenant of the proposed Transferee to the effect that the proposed Transferee
      agrees to be bound by and to abide by the transfer restrictions applicable
      to
      the Class R Certificates.

     

    (iv) Any
      attempted or purported transfer of any Ownership Interest in a Class R
      Certificate in violation of the provisions of this Section shall be absolutely
      null and void and shall vest no rights in the purported Transferee. If any
      purported Transferee shall, in violation of the provisions of this Section,
      become a Holder of a Class R Certificate, then the prior Holder of such Class
      R
      Certificate that is a Permitted Transferee shall, upon discovery that the
      registration of transfer of such Class R Certificate was not in fact permitted
      by this Section, be restored to all rights as Holder thereof retroactive to the
      date of registration of transfer of such Class R Certificate. The Securities
      Administrator shall be under no liability to any Person for any registration
      of
      transfer of a Class R Certificate that is in fact not permitted by this Section
      or for making any distributions due on such Class R 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 Securities Administrator received
      the documents specified in clause (iii). The Securities Administrator shall
      be
      entitled to recover from any Holder of a Class R Certificate that was in fact
      not a Permitted Transferee at the time such distributions were made all
      distributions made on such Class R Certificate. Any such distributions so
      recovered by the Securities Administrator shall be distributed and delivered
      by
      the Securities Administrator to the prior Holder of such Class R Certificate
      that is a Permitted Transferee.

     

    (v) If
      any
      Person other than a Permitted Transferee acquires any Ownership Interest in
      a
      Class R Certificate in violation of the restrictions in this Section, then
      the
      Securities Administrator shall have the right but not the obligation, without
      notice to the Holder of such Class R Certificate or any other Person having
      an
      Ownership Interest therein, to notify the Depositor to arrange for the sale
      of
      such Class R Certificate. The proceeds of such sale, net of commissions (which
      may include commissions payable to the Depositor or its affiliates in connection
      with such sale), expenses and taxes due, if any, will be remitted by the
      Securities Administrator to the previous Holder of such Class R Certificate
      that
      is a Permitted Transferee, except that in the event that the Securities
      Administrator determines that the Holder of such Class R Certificate may be
      liable for any amount due under this Section or any other provisions of this
      Agreement, the Securities Administrator may withhold a corresponding amount
      from
      such remittance as security for such claim. The terms and conditions of any
      sale
      under this clause (v) shall be determined in the sole discretion of the
      Securities Administrator and it shall not be liable to any Person having an
      Ownership Interest in a Class R Certificate as a result of its exercise of
      such
      discretion.

     

    (vi) If
      any
      Person other than a Permitted Transferee acquires any Ownership Interest in
      a
      Class R Certificate in violation of the restrictions in this Section, then
      the
      Securities Administrator upon receipt of reasonable compensation will provide
      to
      the Internal Revenue Service, and to the persons specified in Sections
      860E(e)(3) and (6) of the Code, information needed to compute the tax imposed
      under Section 860E(e)(5) of the Code on transfers of Class R interests to
      Disqualified Organizations.

     

    The
      foregoing provisions of this Section shall cease to apply to transfers occurring
      on or after the date on which there shall have been delivered to the Securities
      Administrator, in form and substance satisfactory to the Securities
      Administrator, (i) written notification from each Rating Agency that the removal
      of the restrictions on transfer set forth in this Section will not cause such
      Rating Agency to downgrade its rating of the Certificates and (ii) an Opinion
      of
      Counsel to the effect that such removal will not cause any REMIC created
      hereunder to fail to qualify as a REMIC. The Holder of the Class R Certificate
      issued hereunder, while not a Disqualified Organization, is the Tax Matters
      Person.

     

    (e) Subject
      to the preceding subsections, upon surrender for registration of transfer of
      any
      Certificate at any office or agency of the Securities Administrator maintained
      for such purpose pursuant to Section 8.11, the Securities Administrator
      shall execute, authenticate and deliver, in the name of the designated
      Transferee or Transferees, one or more new Certificates of the same Class of
      a
      like aggregate Percentage Interest.

     

    (f) At
      the
      option of the Holder thereof, any Certificate may be exchanged for other
      Certificates of the same Class with Authorized Denominations and a like
      aggregate Percentage Interest, upon surrender of such Certificate to be
      exchanged at any office or agency of the Securities Administrator maintained
      for
      such purpose pursuant to Section 8.11. Whenever any Certificates are so
      surrendered for exchange, the Securities Administrator shall execute,
      authenticate and deliver, the Certificates which the Certificateholder making
      the exchange is entitled to receive. Every Certificate presented or surrendered
      for transfer or exchange shall (if so required by the Securities Administrator)
      be duly endorsed by, or be accompanied by a written instrument of transfer
      in
      the form satisfactory to the Securities Administrator duly executed by, the
      Holder thereof or his attorney duly authorized in writing.

     

    (g) No
      service charge to the Certificateholders shall be made for any transfer or
      exchange of Certificates, but the Securities Administrator may require payment
      of a sum sufficient to cover any tax or governmental charge that may be imposed
      in connection with any transfer or exchange of Certificates.

     

    (h) All
      Certificates surrendered for transfer and exchange shall be canceled and
      destroyed by the Securities Administrator in accordance with its customary
      procedures.

     

    Section
      5.3 Mutilated,
      Destroyed, Lost or Stolen Certificates.

     

    If
      (i)
      any mutilated Certificate is surrendered to the Securities Administrator, or
      the
      Securities Administrator receives evidence to its satisfaction of the
      destruction, loss or theft of any Certificate and of the ownership thereof,
      and
      (ii) there is delivered to Securities Administrator such security or indemnity
      as may be required by it to save it harmless, then, in the absence of actual
      knowledge by the Securities Administrator that such Certificate has been
      acquired by a protected purchaser, the Securities Administrator, shall execute,
      authenticate and deliver, in exchange for or in lieu of any such mutilated,
      destroyed, lost or stolen Certificate, a new Certificate of the same Class
      and
      of like denomination and Percentage Interest. Upon the issuance of any new
      Certificate under this Section, the Securities Administrator 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 Securities Administrator) connected therewith. Any
      replacement Certificate issued pursuant to this Section shall constitute
      complete and indefeasible evidence of ownership in the applicable REMIC created
      hereunder, as if originally issued, whether or not the lost, stolen or destroyed
      Certificate shall be found at any time.

     

    Section
      5.4 Persons
      Deemed Owners.

     

    The
      Depositor, the Servicers, the Trustee, the Master Servicer, the Securities
      Administrator and any agent of any of them may treat the Person in whose name
      any Certificate is registered as the owner of such Certificate for the purpose
      of receiving distributions pursuant to Section 4.1 and for all other
      purposes whatsoever, and none of the Depositor, the Servicers, the Trustee,
      the
      Master Servicer, the Securities Administrator or any agent of any of them shall
      be affected by notice to the contrary.

     

    Section
      5.5 Certain
      Available Information.

     

    On
      or
      prior to the date of the first sale of any Junior Subordinate Certificate or
      Class P Certificate to an Independent third party, the Depositor shall provide
      to the Securities Administrator ten copies of any private placement memorandum
      or other disclosure document used by the Depositor in connection with the offer
      and sale of such Certificate. In addition, if any such private placement
      memorandum or disclosure document is revised, amended or supplemented at any
      time following the delivery thereof to the Securities Administrator, the
      Depositor promptly shall inform the Securities Administrator of such event
      and
      shall deliver to the Securities Administrator ten copies of the private
      placement memorandum or disclosure document, as revised, amended or
      supplemented. The Securities Administrator shall maintain at its office as
      set
      forth in Section 11.5 hereof and shall make available free of charge during
      normal business hours for review by any Holder of a Certificate or any Person
      identified to the Securities Administrator as a prospective transferee of a
      Certificate, originals or copies of the following items: (i) in the case of
      a
      Holder or prospective transferee of a Junior Subordinate Certificate or Class
      P
      Certificate, the private placement memorandum or other disclosure document
      relating to such Class of Certificates, in the form most recently provided
      to
      the Securities Administrator; and (ii) in all cases, (A) this Agreement and
      any
      amendments hereof entered into pursuant to Section 11.1, (B) all monthly
      statements required to be delivered to Certificateholders of the Junior
      Subordinate Certificates and Class P Certificates pursuant to Section 4.6
      since the Closing Date, and all other notices, reports, statements and written

    THE
      DEPOSITOR AND THE MASTER SERVICER

     

    Section
      6.1 Liability
      of the Depositor and the Master Servicer.

     

    The
      Depositor and the Master Servicer each shall be liable in accordance herewith
      only to the extent of the obligations specifically imposed by this Agreement
      upon them in their respective capacities as Depositor and Master Servicer and
      undertaken hereunder by the Depositor and the Master Servicer
      herein.

     

    Section
      6.2 Merger
      or Consolidation of the Depositor or the Master Servicer.

     

    Subject
      to the following paragraph, the Depositor shall keep in full effect its
      existence, rights and franchises as a corporation under the laws of the
      jurisdiction of its incorporation. Subject to the following paragraph, the
      Master Servicer shall keep in full effect its existence, rights and franchises
      as a corporation under the laws of the jurisdiction of its formation. The
      Depositor and the Master Servicer each shall obtain and preserve its
      qualification to do business as a foreign corporation in each jurisdiction
      in
      which such qualification is or shall be necessary to protect the validity and
      enforceability of this Agreement, the Certificates or any of the Loans and
      to
      perform its respective duties under this Agreement.

     

    The
      Depositor or the Master Servicer may be merged or consolidated with or into
      any
      Person, or transfer all or substantially all of its assets to any Person, in
      which case any Person resulting from any merger or consolidation to which the
      Depositor or the Master Servicer shall be a party, or any Person succeeding
      to
      the business of the Depositor or the Master Servicer, shall be the successor
      of
      the Depositor or the Master Servicer, as the case may be, hereunder, without
      the
      execution or filing of any paper or any further act on the part of any of the
      parties hereto, anything herein to the contrary notwithstanding; provided,
      however, that the Rating Agencies’ ratings of the Certificates in effect
      immediately prior to such merger or consolidation will not be qualified, reduced
      or withdrawn as a result thereof (as evidenced by a letter to such effect from
      the Rating Agencies).

     

    Section
      6.3 Limitation
      on Liability of the Depositor, the Master Servicer, the Servicers, the
      Securities Administrator and Others.

     

    None
      of
      the Depositor, the Master Servicer, the Securities Administrator, the Servicers
      or any of the directors, officers, employees or agents of the Depositor, the
      Master Servicer, the Securities Administrator or the Servicers shall be under
      any liability to the Trust Fund or the Certificateholders for any action taken
      or for refraining from the taking of any action in good faith pursuant to this
      Agreement or the Servicing Agreements, or for errors in judgment; provided,
      however, that this provision shall not protect the Depositor, the Master
      Servicer, the Securities Administrator, the Servicers or any such person against
      any breach of warranties, representations or covenants made herein or in the
      Servicing Agreements, or against any specific liability imposed on the Master
      Servicer, the Securities Administrator or the Servicers pursuant hereto or
      pursuant to the Servicing Agreements, or against any liability which would
      otherwise be imposed by reason of willful misfeasance, bad faith or gross
      negligence in the performance of duties or by reason of reckless disregard
      of
      obligations and duties hereunder or under the Servicing Agreements. The
      Depositor, the Master Servicer, the Securities Administrator, the Servicers
      and
      any director, officer, employee or agent of the Depositor, the Master Servicer,
      the Securities Administrator or the Servicers may rely in good faith on any
      document of any kind which, prima
      facie,
      is
      properly executed and submitted by any Person respecting any matters arising
      hereunder or under the Servicing Agreements. The Depositor, the Master Servicer,
      the Servicers, the Securities Administrator, the Custodians and any director,
      officer, employee or agent of the Depositor, the Master Servicer, the Servicers,
      the Custodians or the Securities Administrator shall be indemnified and held
      harmless by the Trust Fund against any loss, liability or expense incurred
      in
      connection with any legal action relating to this Agreement, the Certificates
      or
      any Servicing Agreement, or any loss, liability or expense incurred by any
      of
      such Persons other than by reason of such Person’s willful misfeasance, bad
      faith or gross negligence in the performance of its duties hereunder or by
      reason of reckless disregard of its obligations and duties hereunder. None
      of
      the Depositor, the Master Servicer, the Securities Administrator, the Custodian
      or any Servicer shall be under any obligation to appear in, prosecute or defend
      any legal action unless such action is related to its respective duties under
      this Agreement, the Custodial Agreement or the applicable Servicing Agreement
      and, in its opinion, does not involve it in any expense or liability; provided,
      however, that each of the Depositor, the Master Servicer, the Securities
      Administrator, the Custodians may in its discretion undertake any such action
      which it may deem necessary or desirable with respect to this Agreement and
      the
      rights and duties of the parties hereto and the interests of the
      Certificateholders hereunder. In such event, the legal expenses and costs of
      such action and any liability resulting therefrom (except any loss, liability
      or
      expense incurred by reason of willful misfeasance, bad faith or gross negligence
      in the performance of duties hereunder or by reason of reckless disregard of
      obligations and duties hereunder) shall be expenses, costs and liabilities
      of
      the Trust Fund, and the Depositor, the Master Servicer, the Custodians, the
      Servicers and the Securities Administrator shall be entitled to be reimbursed
      therefor from the Distribution Account as and to the extent provided in Article
      III, any such right of reimbursement being prior to the rights of the
      Certificateholders to receive any amount in the Distribution
      Account.

     

    Section
      6.4 Limitation
      on Resignation of the Master Servicer.

     

    The
      Master Servicer shall not resign from the obligations and duties hereby imposed
      on it except upon determination that its duties hereunder are no longer
      permissible under applicable law. Any such determination pursuant to the
      preceding sentence permitting the resignation of the Master Servicer shall
      be
      evidenced by an Opinion of Counsel to such effect obtained at the expense of
      the
      Master Servicer and delivered to the Trustee and the Rating Agencies. No
      resignation of the Master Servicer shall become effective until the Trustee
      or a
      successor Master Servicer shall have assumed the Master Servicer’s
      responsibilities, duties, liabilities (other than those liabilities arising
      prior to the appointment of such successor) and obligations under this
      Agreement.

     

    Section
      6.5 Assignment
      of Master Servicing.

     

    The
      Master Servicer may sell and assign its rights and delegate its duties and
      obligations in its entirety as Master Servicer under this Agreement; provided,
      however, that: (i) the purchaser or transferee accepting such assignment and
      delegation (a) shall be a Person which shall be qualified to service mortgage
      loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less
      than
      $25,000,000 (unless otherwise approved by each Rating Agency pursuant to clause
      (ii) below); (c) shall be reasonably satisfactory to the Trustee (as evidenced
      in a writing signed by the Trustee); and (d) shall execute and deliver to the
      Trustee an agreement, in form and substance reasonably satisfactory to the
      Trustee, which contains an assumption by such Person of the due and punctual
      performance and observance of each covenant and condition to be performed or
      observed by it as master servicer under this Agreement, any custodial agreement
      from and after the effective date of such agreement; (ii) each Rating Agency
      shall be given prior written notice of the identity of the proposed successor
      to
      the Master Servicer and each Rating Agency’s rating of the Certificates in
      effect immediately prior to such assignment, sale and delegation will not be
      downgraded, qualified or withdrawn as a result of such assignment, sale and
      delegation, as evidenced by a letter to such effect delivered to the Master
      Servicer and the Trustee; and (iii) the Master Servicer assigning and selling
      the master servicing shall deliver to the Trustee an officer’s certificate and
      an Opinion of Independent counsel, each stating that all conditions precedent
      to
      such action under this Agreement have been completed and such action is
      permitted by and complies with the terms of this Agreement. No such assignment
      or delegation shall affect any liability of the Master Servicer arising prior
      to
      the effective date thereof.

     

    Section
      6.6 Rights
      of the Depositor in Respect of the Master Servicer.

     

    The
      Master Servicer shall afford the Depositor and the Trustee, upon reasonable
      notice, during normal business hours, access to all records maintained by the
      Master Servicer in respect of the Master Servicer’s rights and obligations
      hereunder and access to officers of the Master Servicer responsible for such
      obligations. Upon request, the Master Servicer shall furnish to the Depositor
      and the Trustee the most recent financial statements of its parent and such
      other information relating to the Master Servicer’s capacity to perform its
      obligations under this Agreement as it possesses. To the extent such information
      is not otherwise available to the public, the Depositor and the Trustee shall
      not disseminate any information obtained pursuant to the preceding two sentences
      without the Master Servicer’s written consent, except as required pursuant to
      this Agreement or to the extent that it is appropriate to do so (i) in working
      with legal counsel, auditors, taxing authorities or other governmental agencies
      or (ii) pursuant to any law, rule, regulation, order, judgment, writ, injunction
      or decree of any court or governmental authority having jurisdiction over the
      Depositor, the Trustee or the Trust Fund, and in any case, the Depositor or
      the
      Trustee, as the case may be, shall use its best efforts to assure the
      confidentiality of any such disseminated non-public information. The Depositor
      may, but is not obligated to, enforce the obligations of the Master Servicer
      under this Agreement and may, but is not obligated to, perform, or cause a
      designee to perform, any defaulted obligation of the Master Servicer under
      this
      Agreement or exercise the rights of the Master Servicer under this Agreement;
      provided that the Master Servicer shall not be relieved of any of its
      obligations under this Agreement by virtue of such performance by the Depositor
      or its designee. The Depositor shall not have any responsibility or liability
      for any action or failure to act by the Master Servicer and is not obligated
      to
      supervise the performance of the Master Servicer under this Agreement or
      otherwise.

     

    Section
      6.7 Transfer
      of Servicing by Sponsor of the Loans Serviced by GMAC; Special
      Servicer.

     

    (a) The
      Sponsor may, at its option, transfer the servicing responsibilities of GMAC
      as a
      Servicer with respect to the related Loans at any time without cause. No such
      transfer shall become effective unless and until a successor to GMAC shall
      have
      been appointed to service and administer the related Loans pursuant to the
      terms
      and conditions of the GMAC Servicing Agreement or a servicing agreement that
      is
      reasonably acceptable to the Sponsor, the Master Servicer and the Rating
      Agencies. No appointment shall be effective unless (i) such successor to GMAC
      meets the eligibility criteria set forth in this Section 6.7, (ii) the
      Master Servicer shall have consented to such appointment, (iii) the Rating
      Agencies have confirmed in writing that such appointment will not result in
      a
      downgrade, qualification or withdrawal of the then current ratings assigned
      to
      the Certificates and (iv) all amounts reimbursable to GMAC under the GMAC
      Servicing Agreement shall have been paid to GMAC, and all servicing transfer
      costs incurred by the Master Servicer shall have been paid to it, by the
      successor appointed pursuant to the terms of this Section 6.7 or by the
      Sponsor including, without limitation, all unreimbursed Monthly Advances and
      Servicing Advances made by GMAC and all out-of-pocket expenses of GMAC incurred
      in connection with the transfer of servicing to such successor. The Sponsor
      shall provide a copy of the written confirmation of the Rating Agencies and
      the
      servicing agreement executed by such successor to the Trustee, the Securities
      Administrator and the Master Servicer. In connection with such appointment
      and
      assumption described herein, the Sponsor may make such arrangements for the
      compensation of such successor out of payments on Loans as it and such successor
      shall agree; provided, however, that no such compensation shall be in excess
      of
      that permitted GMAC under the GMAC Servicing Agreement. The Sponsor shall take
      such action, consistent with this Agreement, as shall be necessary to effectuate
      any such succession.

     

    Notwithstanding
      the foregoing, any successor to GMAC appointed under this Agreement must (i)
      be
      an established mortgage loan servicing institution that is a Fannie Mae and
      Freddie Mac approved seller/servicer, (ii) be approved by each Rating Agency
      by
      a written confirmation from each Rating Agency that the appointment of such
      successor Servicer would not result in the reduction or withdrawal of the then
      current ratings of any outstanding Class of Certificates, (iii) have a net
      worth
      of not less than $25,000,000 and (iv) assume all the responsibilities, duties
      or
      liabilities of GMAC (other than liabilities of GMAC incurred prior to the
      transfer of servicing from GMAC) under the GMAC Servicing Agreement in
      connection with the servicing and administration of the related Loans or a
      servicing agreement that is reasonably acceptable to the Sponsor, the Master
      Servicer and the Rating Agencies.

     

    (b) In
      addition, if any Loan serviced by GMAC becomes ninety (90) days or more
      delinquent, the Sponsor shall have the option to transfer servicing with respect
      to such delinquent Loan to a Special Servicer. Immediately upon the transfer
      of
      servicing to the Special Servicer with respect to any Loan, the Special Servicer
      shall service such Loan in accordance with the applicable GMAC Servicing
      Agreement and a Special Servicer Agreement. Upon the exercise of such option
      and
      with respect to Loans that currently or subsequently become ninety (90) days
      or
      more delinquent, servicing on such Loans will transfer to the Special Servicer,
      upon prior written notice to the Master Servicer, without any further action
      by
      the Sponsor. Any Special Servicer Agreement shall be acceptable to the Master
      Servicer, the Trustee and the Rating Agencies and will not modify any material
      terms of the applicable GMAC Servicing Agreement, including but not limited
      to,
      increasing the Servicing Fee which was payable to GMAC with respect to such
      Loan. Notwithstanding anything to the contrary contained herein, upon the
      transfer of servicing with respect to any such Loan to the Special Servicer,
      GMAC (or any successor thereto other than the Special Servicer) shall have
      no
      further rights, obligations or liabilities with respect to such Loan. If any
      Mortgage Loan is serviced by the Special Servicer and subsequently becomes
      less
      than ninety (90) days delinquent, such Mortgage Loan shall be serviced by the
      Special Servicer in accordance with the applicable GMAC Servicing Agreement
      exclusively, without regard to any Special Servicer Agreement. Upon the
      appointment of the Special Servicer all provisions of the applicable GMAC
      Servicing Agreement shall be binding on and enforceable against the Special
      Servicer as if such Special Servicer was an original signatory and party to
      the
      applicable GMAC Servicing Agreement. Any costs and expenses of the Master
      Servicer in connection with the negotiation, execution and delivery of any
      Special Servicer Agreement and the transfer of servicing to a Special Servicer
      shall be an expense of the Sponsor. In the event that a Special Servicer is
      appointed under this Agreement, the Master Servicer and the Securities
      Administrator shall be entitled with respect to such Special Servicer and its
      related Special Servicer Agreement, to all the benefits, rights, indemnities
      and
      limitations on liability accorded to them under this Agreement and the related
      Servicing Agreement in respect of GMAC.

      or
      the Trustee may, and at the written direction of the Holders of Certificates
      evidencing, in aggregate, not less than 51% of the aggregate Certificate
      Principal Balance of the Certificates, the Trustee shall, by notice in writing
      to the Master Servicer (and to the Depositor if given by the Trustee or to
      the
      Trustee if given by the Depositor) with a copy to each Rating Agency, terminate
      all of the rights and obligations of the Master Servicer (and the Securities
      Administrator if the Master Servicer and the Securities Administrator are the
      same entity) in its capacity as Master Servicer (and in its capacity as
      Securities Administrator if the Master Servicer and the Securities Administrator
      are the same entity) under this Agreement, to the extent permitted by law,
      and
      in and to the Loans and the proceeds thereof. Except as otherwise provided
      in
      Section 7.4, if a Master Servicer Event of Default described in clause (vi)
      hereof shall occur, the Trustee shall, by notice in writing to the Master
      Servicer and the Depositor, terminate all of the rights and obligations of
      the
      Master Servicer (and the Securities Administrator if the Master Servicer and
      the
      Securities Administrator are the same entity) in its capacity as Master Servicer
      under this Agreement (and in its capacity as Securities Administrator if the
      Master Servicer and the Securities Administrator are the same entity) and in
      and
      to the Loans and the proceeds thereof. On or after the receipt by the Master
      Servicer of such written notice, all authority and power of the Master Servicer
      (and, if applicable, the Securities Administrator) under this Agreement, whether
      with respect to the Certificates (other than as a Holder of any Certificate)
      or
      the Loans or otherwise, shall pass to and be vested in the Trustee pursuant
      to
      and under this Section, and, without limitation, the Trustee is hereby
      authorized and empowered, as attorney-in-fact or otherwise, to execute and
      deliver, on behalf of and at the expense of the Master Servicer, (and, if
      applicable, the Securities Administrator) any and all documents and other
      instruments and to do or accomplish all other acts or things necessary or
      appropriate to effect the purposes of such notice of termination, whether to
      complete the transfer and endorsement or assignment of the Loans and related
      documents, or otherwise. The Master Servicer (and, if applicable, the Securities
      Administrator) agrees promptly (and in any event no later than ten Business
      Days
      subsequent to such notice) to provide the Trustee with all documents and records
      requested by it to enable it to assume the Master Servicer’s (and, if
      applicable, the Securities Administrator’s) functions under this Agreement, and
      to cooperate with the Trustee in effecting the termination of the Master
      Servicer’s (and, if applicable, the Securities Administrator’s) responsibilities
      and rights under this Agreement (provided, however, that the Master Servicer
      shall continue to be entitled to receive all amounts accrued or owing to it
      under this Agreement on or prior to the date of such termination, whether in
      respect of Advances or otherwise, and shall continue to be entitled to the
      benefits of Section 6.3, notwithstanding any such termination, with respect
      to events occurring prior to such termination). For purposes of this
      Section 7.1, the Trustee shall not be deemed to have knowledge of a Master
      Servicer Event of Default unless a Responsible Officer of the Trustee assigned
      to and working in the Trustee’s Corporate Trust Office has actual knowledge
      thereof or unless written notice of any event which is in fact such a Master
      Servicer Event of Default is received by the Trustee and such notice references
      the Certificates, the Trust or this Agreement. The Trustee shall promptly notify
      the Rating Agencies of the occurrence of a Master Servicer Event of Default
      of
      which it has knowledge as provided above.

     

    Section
      7.2 Trustee
      to Act; Appointment of Successor.

     

    On
      and
      after the time the Master Servicer receives a notice of termination, the Trustee
      shall be the successor in all respects to the Master Servicer (and, if
      applicable, the Securities Administrator) in its capacity as Master Servicer
      (and, if applicable, the Securities Administrator) under this Agreement and
      the
      transactions set forth or provided for herein, and all the responsibilities,
      duties and liabilities relating thereto and arising thereafter shall be assumed
      by the Trustee (except for any representations or warranties of the Master
      Servicer under this Agreement, the responsibilities, duties and liabilities
      contained in Section 2.3 and the obligation to deposit amounts in respect
      of losses pursuant to Section 3.23(c)) by the terms and provisions hereof
      including, without limitation, the Master Servicer’s obligations to make
      Advances no later than each Distribution Date pursuant to Section 4.7;
      provided, however, if the Trustee is prohibited by law or regulation from
      obligating itself to make advances regarding delinquent mortgage loans, then
      the
      Trustee shall not be obligated to make Advances pursuant to Section 4.7;
      and provided further, that any failure to perform such duties or
      responsibilities caused by the Master Servicer’s failure to provide information
      required by Section 7.1 shall not be considered a default by the Trustee as
      successor to the Master Servicer hereunder. As compensation therefor, the
      Trustee shall be entitled to the Master Servicing Fee and all funds relating
      to
      the Loans, investment earnings on the Distribution Account and all other
      remuneration to which the Master Servicer would have been entitled if it had
      continued to act hereunder. Notwithstanding the above and subject to the
      immediately following paragraph, the Trustee may, if it shall be unwilling
      to so
      act, or shall, if it is unable to so act or if it is prohibited by law from
      making advances regarding delinquent mortgage loans or if the Holders of
      Certificates evidencing, in aggregate, not less than 51% of the Certificate
      Principal Balance of the Certificates so request in writing promptly appoint
      or
      petition a court of competent jurisdiction to appoint, an established mortgage
      loan servicing institution acceptable to each Rating Agency and having a net
      worth of not less than $25,000,000, as the successor to the Master Servicer
      under this Agreement in the assumption of all or any part of the
      responsibilities, duties or liabilities of the Master Servicer under this
      Agreement.

     

    No
      appointment of a successor to the Master Servicer (and, if applicable, the
      Securities Administrator) under this Agreement shall be effective until the
      assumption by the successor of all of the Master Servicer’s (and, if applicable,
      the Securities Administrator’s) responsibilities, duties and liabilities
      hereunder. In connection with such appointment and assumption described herein,
      the Trustee may make such arrangements for the compensation of such successor
      out of payments on Loans as it and such successor shall agree; provided,
      however, that no such compensation shall be in excess of that permitted the
      Master Servicer (and, if applicable, the Securities Administrator) as such
      hereunder. The Depositor, the Trustee and such successor shall take such action,
      consistent with this Agreement, as shall be necessary to effectuate any such
      succession. Pending appointment of a successor to the Master Servicer (and,
      if
      applicable, the Securities Administrator) under this Agreement, the Trustee
      shall act in such capacity as hereinabove provided. The transition costs and
      expenses incurred by the Trustee in connection with the replacement of the
      Master Servicer (and, if applicable, the Securities Administrator) shall be
      reimbursed out of the Trust Fund.

     

    Section
      7.3 Notification
      to Certificateholders.

     

    (a) Upon
      any
      termination of the Master Servicer pursuant to Section 7.1 or any
      appointment of a successor to the Master Servicer pursuant to Section 7.2,
      the Trustee shall give prompt written notice thereof to the Certificateholders
      at their respective addresses appearing in the Certificate
      Register.

     

    (b) Not
      later
      than the later of 60 days after the occurrence of any event, which constitutes
      or which, with notice or lapse of time or both, would constitute a Master
      Servicer Event of Default or five days after a Responsible Officer of the
      Trustee becomes aware of the occurrence of such an event, the Trustee shall
      transmit by mail to all Holders of Certificates notice of each such occurrence,
      unless such default or Master Servicer Event of Default shall have been cured
      or
      waived.

     

    Section
      7.4 Waiver
      of Master Servicer Events of Default.

     

    The
      Holders evidencing, in aggregate, not less than 66-2/3% of the aggregate
      Percentage Interests of all Certificates affected by any default or Master
      Servicer Event of Default hereunder may waive such default or Master Servicer
      Event of Default; provided,
      however,
      a
      default or Master Servicer Event of Default under clause (vi) of
      Section 7.1 may be waived only by all of the Holders of the related Regular
      Interest Certificates. Upon any such waiver of a default or Master Servicer
      Event of Default, such default or Master Servicer Event of Default shall cease
      to exist and shall be deemed to have been remedied for every purpose hereunder.
      No such waiver shall extend to any subsequent or other default or Master
      Servicer Event of Default or impair any right consequent thereon except to
      the
      extent expressly so waived.

     

    
      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

    

     

    ARTICLE
      VIII

    CONCERNING
      THE TRUSTEE AND THE SECURITIES ADMINISTRATOR

     

    Section
      8.1 Duties
      of Trustee and Securities Administrator.

     

    The
      Trustee, prior to the occurrence of a Master Servicer Event of Default and
      after
      the curing or waiver of all Master Servicer Events of Default which may have
      occurred, and the Securities Administrator each undertake to perform such duties
      and only such duties as are specifically set forth in this Agreement as duties
      of the Trustee and the Securities Administrator, respectively. During the
      continuance of a Master Servicer Event of Default, the Trustee shall exercise
      such of the rights and powers vested in it by this Agreement, and use the same
      degree of care and skill in its exercise as a prudent person would exercise
      or
      use under the circumstances in the conduct of such person’s own affairs. Any
      permissive right of the Trustee enumerated in this Agreement shall not be
      construed as a duty.

     

    Each
      of
      the Trustee and the Securities Administrator, upon receipt of all resolutions,
      certificates, statements, opinions, reports, documents, orders or other
      instruments furnished to it, which are specifically required to be furnished
      pursuant to any provision of this Agreement, shall examine them to determine
      whether they conform on their face to the requirements of this Agreement. If
      any
      such instrument is found not to conform on its face to the requirements of
      this
      Agreement, the Trustee or the Securities Administrator, as the case may be,
      shall take such action as it deems appropriate to have the instrument corrected,
      and if the instrument is not corrected to its satisfaction, the Securities
      Administrator shall provide notice to the Trustee thereof and the Trustee shall
      provide notice to the Certificateholders.

     

    No
      provision of this Agreement shall be construed to relieve the Trustee or the
      Securities Administrator from liability for its own negligent action, its own
      negligent failure to act or its own misconduct; provided,
      however,
      that:

     

    (i) Prior
      to
      the occurrence of a Master Servicer Event of Default, and after the curing
      or
      waiver of all such Master Servicer Events of Default which may have occurred
      with respect to the Trustee and at all times with respect to the Securities
      Administrator, the duties and obligations of the Trustee and the Securities
      Administrator shall be determined solely by the express provisions of this
      Agreement, neither the Trustee nor the Securities Administrator shall be liable
      except for the performance of such duties and obligations as are specifically
      set forth in this Agreement, no implied covenants or obligations shall be read
      into this Agreement against the Trustee or the Securities Administrator and,
      in
      the absence of bad faith on the part of the Trustee or the Securities
      Administrator, respectively, the Trustee or the Securities Administrator,
      respectively, may conclusively rely, as to the truth of the statements and
      the
      correctness of the opinions expressed therein, upon any certificates or opinions
      furnished to the Trustee or the Securities Administrator, respectively, that
      conform to the requirements of this Agreement;

     

    (ii) Neither
      the Trustee nor the Securities Administrator shall be liable for an error of
      judgment made in good faith by a Responsible Officer or Responsible Officers
      of
      the Trustee or an officer or officers of the Securities Administrator,
      respectively, unless it shall be proved that the Trustee or the Securities
      Administrator, respectively, was negligent in ascertaining the pertinent facts;
      and

     

    (iii) Neither
      the Trustee nor the Securities Administrator shall be liable with respect to
      any
      action taken, suffered or omitted to be taken by it in good faith in accordance
      with the direction of the Holders of Certificates evidencing, in aggregate,
      not
      less than 25% (or such other percentage set forth in this Agreement) of the
      aggregate Certificate Principal Balance of the Certificates, relating to the
      time, method and place of conducting any proceeding for any remedy available
      to
      the Trustee or the Securities Administrator or exercising any trust or power
      conferred upon the Trustee or the Securities Administrator under this
      Agreement.

     

    Section
      8.2 Certain
      Matters Affecting Trustee and Securities Administrator.

     

    (a) Except
      as
      otherwise provided in Section 8.1:

     

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

     

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

     

    (iii) Neither
      the Trustee nor the Securities Administrator shall be under any obligation
      to
      exercise any of the trusts or powers vested in it by this Agreement or to
      institute, conduct or defend any litigation hereunder or in relation hereto
      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 or the Securities Administrator, as the case may be,
      reasonable security or indemnity satisfactory to it against the costs, expenses
      and liabilities which may be incurred therein or thereby; nothing contained
      herein shall, however, relieve the Trustee of the obligation, upon the
      occurrence of a Master Servicer Event of Default (which has not been cured
      or
      waived), to exercise such of the rights and powers vested in it by this
      Agreement, and to use the same degree of care and skill in their exercise as
      a
      prudent person would exercise or use under the circumstances in the conduct
      of
      such person’s own affairs;

     

    (iv) Neither
      the Trustee nor the Securities Administrator shall be liable for any action
      taken, suffered or omitted by it in good faith and believed by it to be
      authorized or within the discretion or rights or powers conferred upon it by
      this Agreement;

     

    (v) Prior
      to
      the occurrence of a Master Servicer Event of Default hereunder and after the
      curing or waiver of all Master Servicer Events of Default which may have
      occurred with respect to the Trustee and at all times with respect to the
      Securities Administrator, neither the Trustee nor the Securities Administrator
      shall 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 Certificates evidencing, in
      aggregate, not less than 25% of the Trust Fund; provided,
      however,
      if the
      payment within a reasonable time to the Trustee or the Securities Administrator
      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 or the Securities
      Administrator, as applicable, not reasonably assured to the Trustee or the
      Securities Administrator by such Certificateholders, the Trustee or the
      Securities Administrator, as applicable, may require reasonable indemnity
      satisfactory to it against such expense, or liability from such
      Certificateholders as a condition to taking any such action;

     

    (vi) The
      Trustee may execute any of the trusts or powers hereunder or perform any duties
      hereunder either directly or by or through agents or attorneys and the Trustee
      shall not be responsible for any misconduct or negligence on the part of any
      agent or attorney appointed with due care by it hereunder;

     

    (vii) The
      Securities Administrator shall not be liable for any loss resulting from the
      investment of funds held in the Distribution Account at the direction of the
      Master Servicer pursuant to Section 3.23(c);

     

    (viii) Neither
      the Trustee nor the Securities Administrator shall be liable for any action
      taken, suffered, or omitted to be taken 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;

     

    (ix) The
      Trustee shall not be deemed to have notice of any default or Master Servicer
      Event of Default unless a Responsible Officer of the Trustee has actual
      knowledge thereof or unless written notice of any event which is in fact such
      a
      default is received by the Trustee at the Corporate Trust Office of the Trustee,
      and such notice references the Certificates and this Agreement; and

     

    (x) The
      rights, privileges, protections, immunities and benefits given to the Trustee,
      including, without limitation, its right to be indemnified, are extended to,
      and
      shall be enforceable by, each agent, custodian and other Person employed to
      act
      hereunder.

     

    (b) All
      rights of action under this Agreement or under any of the Certificates,
      enforceable by the Trustee, may be enforced by it without the possession of
      any
      of the Certificates, or the production thereof at the trial or other proceeding
      relating thereto, and any such suit, action or proceeding instituted by the
      Trustee shall be brought in its name for the benefit of all the Holders of
      such
      Certificates, subject to the provisions of this Agreement.

     

    (c) The
      Trustee is hereby directed by the Depositor to execute the Group I Swap
      Agreement on behalf of the Supplemental Interest Trust in the form presented
      to
      it by the Depositor and shall have no responsibility for the contents of the
      Group I Swap Agreement, including, without limitation, the representations
      and
      warranties contained therein. Any funds payable by the Securities Administrator
      on behalf of the Supplemental Interest Trust under the Group I Swap Agreement
      shall be paid from funds of the Supplemental Interest Trust in accordance with
      the terms and provisions of this Agreement. Notwithstanding anything to the
      contrary contained herein or in the Group I Swap Agreement, the Securities
      Administrator shall be responsible for making any payments due to the Group
      I
      Swap Provider under the Group I Swap Agreement from the Group I Available
      Distribution Amount.

     

    (d) None
      of
      the Securities Administrator, the Master Servicer, the Servicers, the Sponsor,
      the Depositor, the Custodian or the Trustee shall be responsible for the acts
      or
      omissions of the others or the Group I Swap Provider, it being understood that
      this Agreement shall not be construed to render those partners joint venturers
      or agents of one another.

     

    Section
      8.3 Trustee
      and Securities Administrator not Liable for Certificates or
      Loans.

     

    The
      recitals contained herein and in the Certificates (other than the signature
      of
      the Securities Administrator, the authentication of the Securities Administrator
      on the Certificates, the acknowledgments of the Trustee contained in Article
      II
      and the representations and warranties of the Trustee in Section 8.12)
      shall be taken as the statements of the Depositor and neither the Trustee nor
      the Securities Administrator assumes any responsibility for their correctness.
      Neither the Trustee nor the Securities Administrator makes any representations
      or warranties as to the validity or sufficiency of this Agreement (other than
      as
      specifically set forth in Section 8.12), the Group I Swap Agreement, or of
      the Certificates (other than the signature of the Securities Administrator
      and
      authentication of the Securities Administrator on the Certificates) or of any
      Loan or related document. The Trustee shall not be accountable for the use
      or
      application by the Depositor of any of the Certificates or of the proceeds
      of
      such Certificates, or for the use or application of any funds paid to the
      Depositor or the Master Servicer in respect of the Loans or deposited in or
      withdrawn from the Distribution Accounts.

     

    Section
      8.4 Trustee,
      Master Servicer and Securities Administrator May Own Certificates.

     

    Each
      of
      the Trustee, the Master Servicer and the Securities Administrator in its
      individual capacity or any other capacity may become the owner or pledgee of
      Certificates and may transact business with other interested parties and their
      Affiliates with the same rights it would have if it were not Trustee, Master
      Servicer or the Securities Administrator.

     

    Section
      8.5 Fees
      and Expenses of Trustee and Securities Administrator.

     

    The
      agreed upon fees of the Trustee and the Securities Administrator hereunder
      and
      of Wells Fargo as the Custodian under the Wells Fargo Custodial Agreement or
      of
      DBNTC as the Custodian under the DBNTC Custodial Agreement shall be paid in
      accordance with a side letter agreement with the Master Servicer and at the
      sole
      expense of the Master Servicer. In addition, the Trustee, the Securities
      Administrator, the Custodians and any director, officer, employee or agent
      of
      the Trustee, the Securities Administrator and the Custodians shall be
      indemnified by the Trust Fund and held harmless against any loss, liability
      or
      expense (including reasonable attorney’s fees and expenses) incurred by the
      Trustee or the Securities Administrator in connection with any default
      administration to be performed by the Trustee or the Securities Administrator
      pursuant to this Agreement or other agreements related hereto(including, without
      limitation, the Group I Swap Agreement) and any claim or legal action or any
      pending or threatened claim or legal action arising out of or in connection
      with
      the acceptance or administration of its respective obligations and duties under
      this Agreement, including other agreements related hereto, other than any loss,
      liability or expense (i) for which the Trustee is indemnified by the Master
      Servicer, (ii) that constitutes a specific liability of the Trustee or the
      Securities Administrator, respectively, pursuant to Section 10.1(g) or
      (iii) any loss, liability or expense incurred by reason of willful misfeasance,
      bad faith or gross negligence by the Trustee, or Securities Administrator in
      the
      performance of its duties hereunder or by reason of reckless disregard of its
      obligations and duties hereunder. The Master Servicer agrees to indemnify the
      Trustee, from, and hold the Trustee harmless against, any loss, liability or
      expense (including reasonable attorney’s fees and expenses) incurred by the
      Trustee by reason of the Master Servicer’s willful misfeasance, bad faith or
      gross negligence in the performance of its duties under this Agreement or by
      reason of the Master Servicer’s reckless disregard of its obligations and duties
      under this Agreement. Such indemnity shall survive the termination or discharge
      of this Agreement and the resignation or removal of the Trustee. Any payment
      hereunder made by the Master Servicer to the Trustee shall be from the Master
      Servicer’s own funds, without reimbursement from REMIC I therefor.

     

    Section
      8.6 Eligibility
      Requirements for Trustee and Securities Administrator.

     

    The
      Trustee and the Securities Administrator shall at all times be a corporation
      or
      an association (other than the Depositor, the Sponsor, the Master Servicer
      or
      any Affiliate of the foregoing) organized and doing business under the laws
      of
      any state or the United States of America, authorized under such laws to
      exercise corporate trust powers, having a combined capital and surplus of at
      least $50,000,000 (or a member of a bank holding company whose capital and
      surplus is at least $50,000,000) and subject to supervision or examination
      by
      federal or state authority. If such corporation or association publishes reports
      of conditions at least annually, pursuant to law or to the requirements of
      the
      aforesaid supervising or examining authority, then for the purposes of this
      Section the combined capital and surplus of such corporation or association
      shall be deemed to be its combined capital and surplus as set forth in its
      most
      recent report of conditions so published. In case at any time the Trustee or
      the
      Securities Administrator, as applicable, shall cease to be eligible in
      accordance with the provisions of this Section, the Trustee or the Securities
      Administrator, as applicable, shall resign immediately in the manner and with
      the effect specified in Section 8.7.

     

    Additionally,
      the Securities Administrator (i) may not be an originator, Master Servicer,
      Servicer, the Depositor or an affiliate of the Depositor unless the Securities
      Administrator is in an institutional trust department, (ii) must be authorized
      to exercise corporate trust powers under the laws of its jurisdiction of
      organization, and (iii) must be rated at least “A/F1” by Fitch, if Fitch is a
      Rating Agency, or the equivalent rating by S&P or Moody’s (or such rating
      acceptable to Fitch pursuant to a rating confirmation). If no successor
      securities administrator shall have been appointed and shall have accepted
      appointment within 60 days after Wells Fargo Bank, N.A., as Securities
      Administrator, ceases to be the securities administrator pursuant to this
      Section 8.6, then the Trustee shall perform the duties of the Securities
      Administrator pursuant to this Agreement. The Trustee shall notify the Rating
      Agencies of any change of Securities Administrator. Notwithstanding the above,
      the Trustee may, if it shall be unwilling to so act, or shall, if it is unable
      to so act, promptly appoint or petition a court of competent jurisdiction to
      appoint, a Person that satisfies the eligibility criteria set forth herein
      as
      the Trustee under this Agreement in the assumption of all or any part of the
      responsibilities, duties or liabilities of the Trustee under this Agreement.
      Wells Fargo Bank, N.A. shall act as Securities Administrator for so long as
      it
      is Master Servicer under this Agreement.

     

    Section
      8.7 Resignation
      and Removal of Trustee and Securities Administrator.

     

    The
      Trustee and the Securities Administrator may at any time resign (including,
      in
      the case of the Securities Administrator, in connection with the resignation
      or
      termination of the Master Servicer) and be discharged from the trust hereby
      created by giving written notice thereof to the Depositor, to the Master
      Servicer, to the Securities Administrator (or the Trustee, if the Securities
      Administrator resigns) and to the Certificateholders. Upon receiving such notice
      of resignation, the Depositor shall promptly appoint a successor trustee or
      successor securities administrator by written instrument, in duplicate, which
      instrument shall be delivered to the resigning Trustee or Securities
      Administrator, as applicable, and to the successor trustee or successor
      securities administrator, as applicable. A copy of such instrument shall be
      delivered to the Certificateholders, the Trustee, the Securities Administrator
      and the Master Servicer by the Depositor. If no successor trustee or successor
      securities administrator shall have been so appointed and have accepted
      appointment within 30 days after the giving of such notice of resignation,
      the
      resigning Trustee or Securities Administrator, as the case may be, may, at
      the
      expense of the Trust Fund, petition any court of competent jurisdiction for
      the
      appointment of a successor trustee, successor securities administrator, Trustee
      or Securities Administrator, as applicable.

     

    If
      at any
      time the Trustee or the Securities Administrator shall cease to be eligible in
      accordance with the provisions of Section 8.6 and shall fail to resign
      after written request therefor by the Depositor, or if at any time the Trustee
      or the Securities Administrator shall become incapable of acting, or shall
      be
      adjudged bankrupt or insolvent, or a receiver of the Trustee or the Securities
      Administrator or of its property shall be appointed, or any public officer
      shall
      take charge or control of the Trustee or the Securities Administrator or of
      its
      property or affairs for the purpose of rehabilitation, conservation or
      liquidation, then the Depositor may remove the Trustee or the Securities
      Administrator, as applicable and appoint a successor trustee or successor
      securities administrator, as applicable, by written instrument, in duplicate,
      which instrument shall be delivered to the Trustee or the Securities
      Administrator so removed and to the successor trustee or successor securities
      administrator. A copy of such instrument shall be delivered to the
      Certificateholders, the Trustee, the Securities Administrator and the Master
      Servicer by the Depositor.

     

    The
      Holders of Certificates evidencing, in aggregate, not less than 51% of the
      Certificate Principal Balance of the Certificates, may at any time remove the
      Trustee or the Securities Administrator and appoint a successor trustee or
      successor securities administrator by written instrument or instruments, in
      triplicate, signed by such Holders or their attorneys-in-fact duly authorized,
      one complete set of which instruments shall be delivered to the Depositor,
      one
      complete set to the Trustee or the Securities Administrator so removed and
      one
      complete set to the successor so appointed. A copy of such instrument shall
      be
      delivered to the Certificateholders, the Trustee (in the case of the removal
      of
      the Securities Administrator), the Securities Administrator (in the case of
      the
      removal of the Trustee) and the Master Servicer by the Depositor. All costs
      and
      expenses incurred by the Trustee in connection with its removal without cause
      hereunder shall be reimbursed to it by the Trust Fund.

     

    Any
      resignation or removal of the Trustee or the Securities Administrator and
      appointment of a successor trustee or successor securities administrator
      pursuant to any of the provisions of this Section shall not become effective
      until acceptance of appointment by the successor trustee or successor securities
      administrator, as applicable, as provided in Section 8.8.

     

    Notwithstanding
      anything to the contrary contained herein, the Master Servicer and the
      Securities Administrator shall at all times be the same Person.

     

    Section
      8.8 Successor
      Trustee or Securities Administrator.

     

    Any
      successor trustee or successor securities administrator appointed as provided
      in
      Section 8.7 shall execute, acknowledge and deliver to the Depositor and its
      predecessor trustee or predecessor securities administrator an instrument
      accepting such appointment hereunder, and thereupon the resignation or removal
      of the predecessor trustee or predecessor securities administrator shall become
      effective and such successor trustee or successor securities administrator
      without any further act, deed or conveyance, shall become fully vested with
      all
      the rights, powers, duties and obligations of its predecessor hereunder, with
      the like effect as if originally named as trustee or securities administrator
      herein. The predecessor trustee or predecessor securities administrator shall
      deliver to the successor trustee or successor securities administrator all
      Loan
      Documents and related documents and statements to the extent held by it
      hereunder, as well as all moneys, held by it hereunder, and the Depositor and
      the predecessor trustee or predecessor securities administrator shall execute
      and deliver such instruments and do such other things as may reasonably be
      required for more fully and certainly vesting and confirming in the successor
      trustee or successor securities administrator all such rights, powers, duties
      and obligations.

     

    No
      successor trustee or successor securities administrator shall accept appointment
      as provided in this Section unless at the time of such acceptance such successor
      trustee or successor securities administrator shall be eligible under the
      provisions of Section 8.6 and the appointment of such successor trustee or
      successor securities administrator shall not result in a downgrading of any
      Class of Certificates by any Rating Agency, as evidenced by a letter from each
      Rating Agency.

     

    Upon
      acceptance of appointment by a successor trustee or successor securities
      administrator as provided in this Section, the Depositor shall mail notice
      of
      the succession of such trustee hereunder to all Holders of the related
      Certificates at their addresses as shown in the Certificate Register. If the
      Depositor fails to mail such notice within 10 days after acceptance of
      appointment by the successor trustee or successor securities administrator,
      the
      successor trustee or successor securities administrator shall cause such notice
      to be mailed at the expense of the Depositor.

     

    Section
      8.9 Merger
      or Consolidation of Trustee or Securities Administrator.

     

    Any
      corporation or association into which the Trustee or the Securities
      Administrator may be merged or converted or with which it may be consolidated
      or
      any corporation or association resulting from any merger, conversion or
      consolidation to which the Trustee or the Securities Administrator shall be
      a
      party, or any corporation or association succeeding to the business of the
      Trustee or the Securities Administrator shall be the successor of the Trustee
      or
      the Securities Administrator hereunder, provided such corporation or association
      shall be eligible under the provisions of Section 8.6, 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.

     

    Section
      8.10 Appointment
      of Co-Trustee or Separate Trustee.

     

    Notwithstanding
      any other provisions hereof, at any time, for the purpose of meeting any legal
      requirements of any jurisdiction in which any part of REMIC I or REMIC A or
      property securing the same may at the time be located, the Trustee shall have
      the power and shall execute and deliver all instruments to appoint one or more
      Persons approved by the Trustee to act as co-trustee or co-trustees, jointly
      with the Trustee, or separate trustee or separate trustees, of all or any part
      of REMIC I or REMIC A, and to vest in such Person or Persons, in such
      capacity, and for the benefit of the Holders of the Certificates, such title
      to
      REMIC I or REMIC A, or any part thereof, and, subject to the other
      provisions of this Section 8.10, such powers, duties, obligations, rights
      and trusts as the Trustee may consider necessary or desirable. No co-trustee
      or
      separate trustee hereunder shall be required to meet the terms of eligibility
      as
      a successor trustee under Section 8.6 hereunder and no notice to Holders of
      Certificates of the appointment of co-trustee(s) or separate trustee(s) shall
      be
      required under Section 8.8 hereof.

     

    In
      the
      case of any appointment of a co-trustee or separate trustee pursuant to this
      Section 8.10 all 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 or co-trustee jointly, except
      to the extent that under any law of any jurisdiction in which any particular
      act
      or acts are to be performed by the Trustee (whether as Trustee hereunder or
      as
      successor to a defaulting Master Servicer hereunder), 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 REMIC
      I or REMIC A or any portion thereof in any such jurisdiction) shall be
      exercised and performed by such separate trustee or co-trustee at the direction
      of the Trustee.

     

    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
      or
      co-trustee shall refer to this Agreement and the conditions of this Article
      VIII. Each separate trustee and co-trustee, upon its acceptance of the trust
      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.

     

    Any
      separate trustee or co-trustee 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 or co-trustee 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 or co-trustee.

     

    Section
      8.11 Appointment
      of Office or Agency.

     

    The
      Securities Administrator shall appoint an office or agency in the City of
      Minneapolis located at Sixth Street and Marquette Avenue, Minneapolis, Minnesota
      55479, where the Certificates may be surrendered for registration of transfer
      or
      exchange, and presented for final distribution and where notices and demands
      to
      or upon the Securities Administrator in respect of the Certificates and this
      Agreement may be served.

     

    Section
      8.12 Representations
      and Warranties of the Trustee.

     

    The
      Trustee hereby represents and warrants to the Master Servicer, the Securities
      Administrator and the Depositor as applicable, as of the Closing Date,
      that:

     

    (i) It
      is a
      national banking association duly organized, validly existing and in good
      standing under the laws of the United States of America.

     

    (ii) The
      execution and delivery of this Agreement by it, and the performance and
      compliance with the terms of this Agreement by it, will not violate its articles
      of incorporation or bylaws or constitute a default (or an event which, with
      notice or lapse of time, or both, would constitute a default) under, or result
      in the breach of, any material agreement or other instrument to which it is
      a
      party or which is applicable to it or any of its assets.

     

    (iii) It
      has
      the full power and authority to enter into and consummate all transactions
      contemplated by this Agreement, has duly authorized the execution, delivery
      and
      performance of this Agreement, and has duly executed and delivered this
      Agreement.

     

    (iv) This
      Agreement, assuming due authorization, execution and delivery by the other
      parties hereto, constitutes a valid, legal and binding obligation of it,
      enforceable against it in accordance with the terms hereof, subject to (A)
      applicable bankruptcy, insolvency, receivership, reorganization, moratorium
      and
      other laws affecting the enforcement of creditors’ rights generally, and (B)
      general principles of equity, regardless of whether such enforcement is
      considered in a proceeding in equity or at law.

     

    (v) It
      is not
      in violation of, and its execution and delivery of this Agreement and its
      performance and compliance with the terms of this Agreement will not constitute
      a violation of, any law, any order or decree of any court or arbiter, or any
      order, regulation or demand of any federal, state or local governmental or
      regulatory authority, which violation, in its good faith and reasonable
      judgment, is likely to affect materially and adversely either the ability of
      it
      to perform its obligations under this Agreement or its financial
      condition.

     

    (vi) No
      litigation is pending or, to the best of its knowledge, threatened against
      it,
      which would prohibit it from entering into this Agreement or, in its good faith
      reasonable judgment, is likely to materially and adversely affect either the
      ability of it to perform its obligations under this Agreement or its financial
      condition.

    Section
      9.1 Termination
      Upon Purchase or Liquidation of the Loans.

     

    (a) Subject
      to Section 9.2, the respective obligations and responsibilities under this
      Agreement of the Depositor, the Master Servicer, the Securities Administrator
      and the Trustee (other than the obligations of the Master Servicer to the

      to
      pay Compensating Interest to the Securities Administrator and the Securities
      Administrator to make payments in respect of REMIC Regular Interests or the

      to the Certificateholders and the deposit of all amounts held by or on behalf
      of
      the Trustee and required hereunder to be so paid or deposited on the
      Distribution Date coinciding with or following the earlier to occur of (i)
      a
      Group I Cleanup Call and a Group II-V Cleanup Call and (ii) the final payment
      or
      other liquidation (or any advance with respect thereto) of the last Loan or
      REO
      Property remaining in REMIC I and REMIC A; provided, however, that in no event
      shall the trust created hereby continue beyond the expiration of 21 years from
      the death of the last survivor of the descendants of Joseph P. Kennedy, the
      late
      ambassador of the United States to the Court of St. James, living on the date
      hereof. 

     

    (b) The
      Master Servicer shall have the right (the party exercising such right, the
      “Group I Terminator”) to purchase all of the Group I Loans and each Group I REO
      Property remaining in REMIC I no later than the Determination Date in the month
      immediately preceding the Distribution Date on which the Group I Certificates
      will be retired (a “Group I Cleanup Call”); provided, however, that the Group I
      Terminator may elect to institute a Group I Cleanup Call only if the aggregate
      Scheduled Principal Balance of the Group I Loans and the fair market value
      of
      each Group I REO Property remaining in the Trust Fund at the time of such
      election is less than or equal to 5% of the aggregate Scheduled Principal
      Balance of the Group I Loans as of the Cut-Off Date. 

     

    (c) The
      Master Servicer shall have the right (the party exercising such right, the
      “Group II-V Terminator”) to purchase all of the Group II-V Loans and each Group
      II-V REO Property remaining in REMIC A no later than the Determination Date
      in
      the month immediately preceding the Distribution Date on which the Group II-V
      Certificates will be retired (a “Group II-V Cleanup Call”); provided, however,
      that the Group II-V Terminator may elect to institute a Group II-V Cleanup
      Call
      only if (a) the aggregate Scheduled Principal Balance of the Group II-V Loans
      and the fair market value of each Group II-V REO Property remaining in the
      Trust
      Fund at the time of such election is less than or equal to 5% of the aggregate
      Scheduled Principal Balance of the Group II-V Loans as of the Cut-Off Date.
      

     

    (d) A
      Group I
      Cleanup Call or Group II-V Cleanup Call shall be at a price (each, a
“Termination Price”) equal to (i)(a) with respect to a Group I Cleanup Call, the
      aggregate Purchase Price of all the Group I Loans and the fair market value
      of
      all Group I REO Properties included in REMIC I or (b) with respect to a Group
      II-V Cleanup Call, the aggregate Purchase Price of all the Group II-V Loans
      and
      the fair market value of all Group II-V REO Properties include in REMIC A,
      (ii)
      in connection with the exercise of a Group I Cleanup Call, any Group I Swap
      Termination Payments payable to the Group I Swap Provider not due to a Group
      I
      Swap Provider Trigger Event, which remains unpaid or which is due to the
      exercise of the optional termination right by the Group I Terminator plus (iii)
      any amounts due the Servicers and the Master Servicer in respect of unpaid
      Servicing Fees, Master Servicing Compensation and outstanding Monthly Advances
      and Servicing Advances. In the event of any such Cleanup Call, the related
      Terminator shall deliver to the Securities Administrator for deposit in the
      related Distribution Account not later than the last Business Day of the month
      next preceding the month of the final distribution on the Certificates an amount
      in immediately available funds equal to the above described Termination Price.
      The Securities Administrator shall remit (a) to the Master Servicer from such
      funds deposited in the related Distribution Account (i) any amounts which the
      Master Servicer notifies it in writing that the Master Servicer would be
      permitted to withdraw and retain from the related Distribution Account pursuant
      to Section 3.24 and (ii) any other amounts otherwise payable by the Securities
      Administrator to the Master Servicer from amounts on deposit in the related
      Distribution Account pursuant to the terms of this Agreement and notified by
      the
      Master Servicer in writing and (b) to the related Servicer, any amounts
      reimbursable to such Servicer pursuant to the related Servicing Agreement,
      in
      each case prior to making any final distributions pursuant to Section 9.1(g)
      below. Upon certification to the Trustee and the Securities Administrator by
      a
      Servicing Officer of the making of such final deposit, the Trustee shall
      promptly release to the related Terminator the Mortgage Files for the remaining
      Group I Loans or Group II-V Loans, as applicable, and the Trustee shall execute
      all assignments, endorsements and other instruments necessary to effectuate
      such
      transfer in each case without recourse, representation or warranty.

     

    (e) Notice
      of
      the liquidation of the Certificates shall be given promptly by the Securities
      Administrator by letter to the Certificateholders mailed (a) in the event such
      notice is given in connection with the purchase of the Loans and each REO
      Property by the Master Servicer, not earlier than the 15th day and not later
      than the 25th day of the month next preceding the month of the final
      distribution on the Certificates or (b) otherwise during the month of such
      final
      distribution on or before the Determination Date in such month, in each case
      specifying (i) the Distribution Date upon which the Trust Fund will terminate
      and the final payment in respect of REMIC Regular Interests or the Certificates
      will be made upon presentation and surrender of the related Certificates at
      the
      office of the Securities Administrator therein designated, (ii) the amount
      of
      any such final payment, (iii) that no interest shall accrue in respect of REMIC
      Regular Interests or Certificates from and after the Interest Accrual Period
      relating to the final Distribution Date therefor and (iv) that the Record Date
      otherwise applicable to such Distribution Date is not applicable, payments being
      made only upon presentation and surrender of the Certificates at the office
      of
      the Securities Administrator. 

     

    (f) Upon
      presentation of the Certificates by the Certificateholders on the final
      Distribution Date, the Securities Administrator shall distribute to each
      Certificateholder so presenting and surrendering its Certificates the amount
      otherwise distributable on such Distribution Date in accordance with
      Section 4.1 in respect of the Certificates so presented and surrendered.
      Any funds not distributed to any Holder or Holders of Certificates being retired
      on such Distribution Date because of the failure of such Holder or Holders
      to
      tender their Certificates shall, on such date, be set aside and held in trust
      and credited to the account of the appropriate non-tendering Holder or Holders.
      If any Certificates as to which notice has been given pursuant to this
      Section 9.1 shall not have been surrendered for cancellation within six
      months after the time specified in such notice, the Securities Administrator
      shall mail a second notice to the remaining non-tendering Certificateholders
      to
      surrender their Certificates for cancellation in order to receive the final
      distribution with respect thereto. If within one year after the second notice
      all such Certificates shall not have been surrendered for cancellation, the
      Securities Administrator shall, directly or through an agent, mail a final
      notice to the remaining non-tendering Certificateholders concerning surrender
      of
      their Certificates. The costs and expenses of maintaining the funds in trust
      and
      of contacting such Certificateholders shall be paid out of the assets (related
      to the Group I Loans in the case of a Group I Cleanup Call or Group II-V Loans
      in the case of a Group II-V Cleanup Call) remaining in the trust fund. If within
      one year after the final notice any such Certificates shall not have been
      surrendered for cancellation, the Securities Administrator shall pay to the
      Depositor all such amounts, and all rights of non-tendering Certificateholders
      in or to such amounts shall thereupon cease. No interest shall accrue or be
      payable to any Certificateholder on any amount held in trust by the Securities
      Administrator as a result of such Certificateholder’s failure to surrender its
      Certificate(s) for final payment thereof in accordance with this
      Section 9.1. Any such amounts held in trust by the Securities Administrator
      shall be held in an Eligible Account and the Securities Administrator may direct
      any depository institution maintaining such account to invest the funds in
      one
      or more Eligible Investments. All income and gain realized from the investment
      of funds deposited in such accounts held in trust by the Securities
      Administrator shall be for the benefit of the Securities Administrator;
provided,
      however,
      that
      the Securities Administrator shall deposit in such account the amount of any
      loss of principal incurred in respect of any such Eligible Investment made
      with
      funds in such accounts immediately upon the realization of such
      loss.

     

    Immediately
      following the deposit of funds in trust hereunder in respect of the
      Certificates, the related REMICs shall terminate.

     

    Section
      9.2 Additional
      Termination Requirements.

     

    (a) In
      the
      event of (x) a Group I Cleanup Call or a Group II-V Cleanup Call or (y) the
      final payment on or other liquidation of the last Loan or REO Property remaining
      in REMIC I or REMIC A pursuant to Section 9.1, the related REMICs shall be

      a qualified liquidation under Section 860F of the Code and any regulations
      thereunder, as evidenced by an Opinion of Counsel obtained by and at the expense
      of the Terminator;

     

    (ii) During
      such 90-day liquidation period and, at or prior to the time of making of the
      final payment on the Certificates, the Securities Administrator shall sell
      all
      of the assets of REMIC I or REMIC A to the Terminator for cash; 

     

    (iii) At
      the
      time of the making of the final payment on the Certificates, the Securities
      Administrator shall distribute or credit, or cause to be distributed or
      credited, to the Holders of the Residual Certificates all cash on hand in the
      Trust Fund (other than cash retained to meet claims), and the Trust Fund shall
      terminate at that time; 

     

    (iv) If
      the
      Trust Fund is being terminated as a result of the occurrence of the event
      described in clause (x) of the first paragraph of this Section 9.2, the Final
      Terminator (as described below), at its own expense, shall prepare or cause
      to
      be prepared the documentation required in connection with the adoption of a
      plan
      of liquidation of each REMIC pursuant to this Section 9.2. The Final Terminator
      pursuant to this Section 9.2(a)(iv) shall be the (A) Group I Terminator if
      the
      Group I Cleanup Call occurs later than the Group II-V Cleanup Call or (B) the

      described in clause (y) of the first paragraph of Section 9.2, at the expense

      prepared the documentation required in connection with the adoption of a plan
      of
      liquidation of each related REMIC pursuant to this Section 9.2.

      Regular Interests, the REMIC II Regular Interests, the REMIC A Regular Interests
      and the interests represented by the Certificates (other than the Class A-R

    (b) The
      Closing Date is hereby designated as the “Startup Day” of each REMIC created
      hereunder within the meaning of Section 860G(a)(9) of the
      Code.

     

    (c) The
      Securities Administrator shall be reimbursed for any and all expenses relating
      to any tax audit of the Trust Fund (including, but not limited to, any
      professional fees or any administrative or judicial proceedings with respect
      to
      each REMIC that involve the Internal Revenue Service or state tax authorities),
      including the expense of obtaining any tax related Opinion of Counsel except
      as
      specified herein. The Securities Administrator, as agent for each REMIC’s tax
      matters person shall (i) act on behalf of the Trust Fund in relation to any
      tax
      matter or controversy involving any REMIC and (ii) represent the Trust Fund

      Section 1.860F-4(d) and Treasury regulations Section 301.6231(a)(7)-1,
      as the tax matters person of the related REMIC created hereunder. By their
      acceptance thereof, the holder of the largest Percentage Interest of the

      Administrator or an Affiliate as its agent to perform all of the duties of
      the
      tax matters person for the Trust Fund.

     

    (d) The
      Securities Administrator shall prepare and file and the Trustee shall sign
      all
      of the Tax Returns in respect of each REMIC created hereunder. The expenses
      of
      preparing and filing such returns shall be borne by the Securities Administrator
      without any right of reimbursement therefor.

     

    (e) The
      Securities Administrator 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,
      as required by the Code, the REMIC Provisions or other such compliance guidance,
      the Securities Administrator shall provide (i) to any Transferor of a Residual
      Certificate such information as is necessary for the application of any tax
      relating to the transfer of a Residual Certificate to any Person who is not
      a
      Permitted Transferee upon receipt of additional reasonable compensation, (ii)
      to
      the Certificateholders such information or reports as are required by the Code
      or the REMIC Provisions including reports relating to interest, original issue
      discount and market discount or premium (using the prepayment assumption (as
      set
      forth in the Prospectus Supplement) as required) and (iii) to the Internal
      Revenue Service the name, title, address and telephone number of the person
      who
      shall serve as the representative of each REMIC. The Depositor shall provide
      or
      cause to be provided to the Securities Administrator, within ten (10) days
      after
      the Closing Date, all information or data that the Securities Administrator
      reasonably determines to be relevant for tax purposes as to the valuations
      and
      issue prices of the Certificates, including, without limitation, the price,
      yield, prepayment assumption and projected cash flow of the
      Certificates.

     

    (f) To
      the
      extent in the control of the Trustee or the Securities Administrator, each
      such
      Person (i) shall take such action and shall cause each REMIC created hereunder
      to take such action as shall be necessary to create or maintain the status
      thereof as a REMIC under the REMIC Provisions, (ii) shall not take any action,
      cause the Trust Fund 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 (A) endanger the status of each REMIC as a REMIC or
      (B)
      result in the imposition of a tax upon the Trust Fund (including but not limited
      to the tax on prohibited transactions as defined in Section 860F(a)(2) of
      the Code and the tax on contributions to a REMIC set forth in
      Section 860G(d) of the Code) (either such event, an “Adverse REMIC Event”)
      unless such action or inaction is permitted under this Agreement or the Trustee
      and the Securities Administrator have received an Opinion of Counsel, addressed
      to them (at the expense of the party seeking to take such action but in no
      event
      at the expense of the Trustee or the Securities Administrator) to the effect
      that the contemplated action will not, with respect to any REMIC, endanger
      such
      status or result in the imposition of such a tax, nor (iii) shall the Securities
      Administrator take or fail to take any action (whether or not authorized
      hereunder) as to which the Trustee has advised it in writing that it has
      received an Opinion of Counsel to the effect that an Adverse REMIC Event could
      occur with respect to such action; provided that the Securities Administrator
      may conclusively rely on such Opinion of Counsel and shall incur no liability
      for its action or failure to act in accordance with such Opinion of Counsel.
      In
      addition, prior to taking any action with respect to any REMIC or the respective
      assets of each, or causing any REMIC to take any action, which is not
      contemplated under the terms of this Agreement, the Securities Administrator
      shall 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 the Securities Administrator shall not 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. The Trustee may consult
      with
      counsel to make such written advice, and the cost of same shall be borne by
      the
      party seeking to take the action not permitted by this Agreement, but in no
      event shall such cost be an expense of the Trustee.

     

    (g) In
      the
      event that any tax is imposed on “prohibited transactions” of any REMIC created
      hereunder as defined in Section 860F(a)(2) of the Code, on the “net income
      from foreclosure property” of such REMIC as defined in Section 860G(c) of
      the Code, on any contributions to any such REMIC after the Startup Day therefor
      pursuant to Section 860G(d) of the Code, or any other tax is imposed by the
      Code or any applicable provisions of state or local tax laws, such tax shall
      be
      charged (i) to the Trustee pursuant to Section 10.3 hereof, if such tax
      arises out of or results from a breach by the Trustee of any of its obligations
      under this Article X, (ii) to the Securities Administrator pursuant to
      Section 10.3 hereof, if such tax arises out of or results from a breach by
      the Securities Administrator of any of its obligations under this Article X,
      (iii) to the Master Servicer pursuant to Section 10.3 hereof, if such tax
      arises out of or results from a breach by the Master Servicer of any of its
      obligations under Article III or under this Article X, or (iv) against amounts
      on deposit in the Distribution Account and shall be paid by withdrawal
      therefrom.

     

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

     

    (i) Following
      the Startup Day, the Trustee shall not accept any contributions of assets to
      any
      REMIC other than in connection with any Substitute Loan delivered in accordance
      with Section 2.3 unless it shall have received an Opinion of Counsel
      addressed to it to the effect that the inclusion of such assets in the Trust
      Fund will not cause the related REMIC to fail to qualify as a REMIC at any
      time
      that any Certificates are outstanding or subject such REMIC to any tax under
      the
      REMIC Provisions or other applicable provisions of federal, state and local
      law
      or ordinances.

     

    (j) Neither
      the Trustee nor the Securities Administrator shall knowingly enter into any
      arrangement by which any REMIC will receive a fee or other compensation for
      services nor permit any REMIC to receive any income from assets other than
      “qualified mortgages” as defined in Section 860G(a)(3) of the Code or
“permitted investments” as defined in Section 860G(a)(5) of the
      Code.

     

    (k) The
      Securities Administrator shall apply for an employer identification number
      with
      the Internal Revenue Service via a Form SS-4 or other comparable method for
      each
      REMIC. In connection with the foregoing, the Securities Administrator shall
      provide the name and address of the person who can be contacted to obtain
      information required to be reported to the holders of Regular Interests in
      each
      REMIC as required by IRS Form 8811.

     

    Section
      10.2 Prohibited
      Transactions and Activities.

     

    None
      of
      the Depositor, the Securities Administrator, the Master Servicer or the Trustee
      shall sell, dispose of or substitute for any of the Loans (except in connection
      with (i) the foreclosure of a Loan, including but not limited to, the
      acquisition or sale of a Mortgaged Property acquired by deed in lieu of
      foreclosure, (ii) the bankruptcy of REMIC I or REMIC A (iii) the
      termination of REMIC I pursuant to Article IX of this Agreement, (iv) a
      substitution pursuant to Article II of this Agreement or (v) a purchase of
      Loans
      pursuant to Article II of this Agreement), nor acquire any assets for any REMIC
      (other than REO Property acquired in respect of a defaulted Loan), nor sell
      or
      dispose of any investments in the Distribution Account for gain, nor accept
      any
      contributions to any REMIC after the Closing Date (other than a Substitute
      Loan
      delivered in accordance with Section 2.3), unless it has received an
      Opinion of Counsel, addressed to the Trustee (at the expense of the party
      seeking to cause such sale, disposition, substitution, acquisition or
      contribution but in no event at the expense of the Trustee) that such sale,
      disposition, substitution, acquisition or contribution will not (a) affect
      adversely the status of any REMIC as a REMIC or (b) cause any REMIC to be
      subject to a tax on “prohibited transactions” or “contributions” pursuant to the
      REMIC Provisions.

     

    Section
      10.3 Indemnification.

      Trustee agrees to be liable for any taxes and costs incurred by the Trust Fund,
      the Depositor, the Securities Administrator or the Master Servicer including,
      without limitation, any reasonable attorneys fees imposed on or incurred by
      the
      Trust Fund, the Depositor, the Securities Administrator or the Master Servicer
      as a result of the Trustee’s failure to perform its covenants set forth in this
      Article X in accordance with the standard of care of the Trustee set forth
      in
      this Agreement.

     

    (b) The
      Master Servicer agrees to indemnify the Trust Fund, the Depositor and the
      Trustee for any taxes and costs including, without limitation, any reasonable
      attorneys’ fees imposed on or incurred by the Trust Fund, the Depositor or the
      Trustee, as a result of the Master Servicer’s failure to perform its covenants
      set forth in Article III in accordance with the standard of care of the Master
      Servicer set forth in this Agreement.

     

    (c) The
      Securities Administrator agrees to be liable for any taxes and costs incurred
      by
      the Trust Fund, the Depositor or the Trustee including, without limitation,
      any
      reasonable attorneys fees imposed on or incurred by the Trust Fund, the
      Depositor or the Trustee as a result of the Securities Administrator’s failure
      to perform its covenants set forth in this Article X in accordance with the
      standard of care of the Securities Administrator set forth in this
      Agreement.

      XI

    MISCELLANEOUS
      PROVISIONS

     

    Section
      11.1 Amendment.
      This
      Agreement may be amended from time to time by the Depositor, the Master
      Servicer, the Securities Administrator and the Trustee, but without the consent
      of any of the Certificateholders, (a) to cure any ambiguity, to correct or
      supplement any provision herein which may be inconsistent with any other
      provision herein, or to make any other provisions with respect to matters or
      questions arising under this Agreement, (b) to ensure compliance with Regulation
      AB or (c) to modify, eliminate or add to any provisions to such extent as shall
      be necessary to maintain the qualification of the Trust Fund as four REMICs
      at
      all times that any Certificates are outstanding, provided, that such action
      shall not, as evidenced by an Opinion of Counsel addressed and delivered to
      the
      Trustee, adversely affect in any material respect the interests of any
      Certificateholder. No amendment shall be deemed to adversely affect in any
      material respect the interests of any Certificateholder who shall have consented
      thereto, and no Opinion of Counsel shall be required to address the effect
      of
      any such amendment on any such consenting Certificateholder.

     

    This
      Agreement may also be amended from time to time by the Depositor, the Master
      Servicer, the Securities Administrator and the Trustee (with the consent of
      the
      Group I Swap Provider only with respect to matters affecting the Group I Swap
      Agreement) and the Holders of Certificates evidencing, in aggregate, not less
      than 66-2/3% of the Trust Fund for the purpose of adding any provisions 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 of Certificates;
provided,
      however, that no such amendment shall (a) reduce in any manner the amount of,
      or
      delay the timing of, payments received on Loans which are required to be
      distributed in respect of any Certificate without the consent of the Holder
      of
      such Certificate; (b) adversely affect in any material respect the interest
      of
      the Holders of the Senior Certificates (other than the Class R Certificates)
      in
      a manner other than as described in (a) above without the consent of the Holders
      of such Senior Certificates (other than the Class R Certificates) aggregating
      not less than 66-2/3% of the aggregate Percentage Interest evidenced by all
      Senior Certificates (other than the Class R Certificates); (c) adversely affect
      in any material respect the interest of the Holders of the Subordinate
      Certificates in a manner other than as described in clause (a) above without
      the
      consent of the Holders of Subordinate Certificates aggregating not less than
      66-2/3% of the aggregate Percentage Interest evidenced by all Subordinate
      Certificates; (d) adversely affect in any material respect the interest of
      the
      Holders of the Class I-P Certificates in a manner other than as described in
      clause (a) above without the consent of the Holders of the Class I-P
      Certificates; (e) adversely affect in any material respect, the interest of
      the
      Holders of the Class II-P Certificates in a manner other than as described
      in
      clause (a) above, without the consent of the Holders of the Class II-P
      Certificates; (f) Class R Certificateholder without the consent of the Holder
      of
      the Class R Certificates; (g) change in any material respect the rights and
      obligations of the Master Servicer or successor Master Servicer under this
      Agreement without the prior written consent of such party; or (h) reduce the
      aforesaid percentage of the Certificates the Holders of which are required
      to
      consent to any such amendments without the consent of the Holders of all
      Certificates then outstanding; provided, that for the purposes of this
      Agreement, the Holder of the Class R Certificate shall have no right to vote
      at
      all times that any Senior Certificates (other than the Class R Certificates),
      or
      Subordinate Certificates are outstanding if such amendment relates to the
      modification, elimination or addition of any provision necessary to maintain
      the
      qualification of the Trust Fund as five REMICs. Without limiting the generality
      of the foregoing, any amendment to this Agreement required in connection with
      the compliance with or the clarification of any reporting obligations described
      in Section 3.18 hereof shall not require the consent of any
      Certificateholder or any Opinion of Counsel or Rating Agency
      confirmation.

     

    Notwithstanding
      any contrary provision of this Agreement, the Trustee shall not consent to
      any
      amendment to this Agreement unless it shall have first received an Opinion
      of
      Counsel addressed to it to the effect that such amendment will not cause any
      of
      REMIC I, REMIC II, REMIC III, REMIC A or REMIC B of the Trust Fund to fail
      to
      qualify as a REMIC at any time that any REMIC Regular Interests or Regular
      Interest Certificates are outstanding.

     

    As
      soon
      as practicable after the execution of any such amendment, the Trustee shall
      furnish written notification of the substance of such amendment to each
      Certificateholder and Rating Agency.

     

    It
      shall
      not be necessary for the consent of the Certificateholders under this
      Section 11.1 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 Certificateholders shall be subject to such reasonable
      regulations as the Trustee may prescribe.

     

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

     

    Section
      11.2 Recordation
      of Agreement; Counterparts.
      To the
      extent permitted by applicable law, this Agreement (or an abstract hereof,
      if
      acceptable by the applicable recording office) is subject to recordation in
      all
      appropriate public offices for real property records in all the counties or
      other comparable jurisdictions in which any or all of the properties subject
      to
      the Mortgages are situated, and in any other appropriate public recording office
      or elsewhere, such recordation to be effected by the Depositor at the expense
      of
      the Certificateholders, but only after the Depositor has delivered to the
      Trustee an Opinion of Counsel to the effect that such recordation materially
      and
      beneficially affects the interests of the Certificateholders.

     

    For
      the
      purpose of facilitating the recordation of this Agreement as herein provided
      and
      for other purposes, this Agreement may be executed simultaneously in any number
      of counterparts, each of which counterparts shall be deemed to be an original,
      and such counterparts shall constitute but one and the same
      instrument.

     

    Section
      11.3 Limitation
      on Rights of Certificateholders.
      The
      death or incapacity of any Certificateholder shall not operate to terminate
      this
      Agreement or the 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 the 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 Certificateholder, shall have any right to vote or in any manner
      otherwise control 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

    No

      have any right by virtue or by availing of any provision of this Agreement
      to
      institute any suit, action or proceeding in equity or at law upon or under
      or
      with respect to this Agreement, unless such holder previously shall have given
      to the Trustee a written notice of default and of the continuance thereof,
      as
      hereinbefore provided, and unless all of the Holders of Certificates evidencing,
      in aggregate, not less than 25% of the Trust Fund 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 costs, expenses and liabilities to
      be
      incurred therein or thereby, and the Trustee, for 60 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; 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 11.3, each and every Certificateholder and the Trustee
      shall be entitled to such relief as can be given either at law or in
      equity.

    Section
      11.8 Article

    Section
      11.9 Grant
      of Security Interest.

     

    It
      is the
      express intent of the parties hereto that the conveyance of the Loans by the
      Depositor to the Trustee, on behalf of the Trust Fund and for the benefit of
      the
      Certificateholders, be, and be construed as, a sale of the Loans by the
      Depositor and not a pledge of the Loans to secure a debt or other obligation
      of
      the Depositor. However, in the event that, notwithstanding the aforementioned
      intent of the parties, the Loans are held to be property of the Depositor,
      then,
      (a) it is the express intent of the parties that such conveyance be deemed
      a
      pledge of the Loans by the Depositor to the Trustee, on behalf of the Trust
      Fund
      and for the benefit of the related Certificateholders, to secure a debt or
      other
      obligation of the Depositor and (b)(1) this Agreement shall also be deemed
      to be
      a security agreement within the meaning of Articles 8 and 9 of the Uniform
      Commercial Code as in effect from time to time in the State of New York; (2)
      the
      conveyance provided for in Section 2.1 hereof shall be deemed to be a grant
      by the Depositor to the Trustee, on behalf of the Trust Fund and for the benefit
      of the related Certificateholders, of a security interest in all of the
      Depositor’s right, title and interest in and to the Loans and all amounts
      payable to the holders of the Loans in accordance with the terms thereof and
      all
      proceeds of the conversion, voluntary or involuntary, of the foregoing into
      cash, instruments, securities or other property, including without limitation
      all amounts, other than investment earnings, from time to time held or invested
      in the Distribution Account, whether in the form of cash, instruments,
      securities or other property; (3) the obligations secured by such security
      agreement shall be deemed to be all of the Depositor’s obligations under this
      Agreement, including the obligation to provide to the Certificateholders the
      benefits of this Agreement relating to the Loans and the Trust Fund; and (4)
      notifications to persons holding such property, and acknowledgments, receipts
      or
      confirmations from persons holding such property, shall be deemed notifications
      to, or acknowledgments, receipts or confirmations from, financial
      intermediaries, bailees or agents (as applicable) of the Trustee for the purpose
      of perfecting such security interest under applicable law. Accordingly, the
      Depositor hereby grants to the Trustee, on behalf of the Trust Fund and for
      the
      benefit of the Certificateholders, a security interest in the Loans and all
      other property described in clause (2) of the preceding sentence, for the
      purpose of securing to the Trustee the performance by the Depositor of the
      obligations described in clause (3) of the preceding sentence. Notwithstanding
      the foregoing, the parties hereto intend the conveyance pursuant to
      Section 2.1 to be a true, absolute and unconditional sale of the Loans and
      assets constituting the Trust Fund by the Depositor to the Trustee, on behalf
      of
      the Trust Fund and for the benefit of the Certificateholders.

     

     

    IN
      WITNESS WHEREOF, the Depositor, the Master Servicer, the Securities
      Administrator and the Trustee have caused their names to be signed hereto by
      their respective officers thereunto duly authorized, all as of the day and
      year
      first above written.

      evidencing
        a fractional undivided interest in the distributions allocable to the Class
        I-A-[1][2][3][4]
        Certificates with respect to a trust fund generally consisting of a pool
        of
        conventional one- to four-family adjustable-rate mortgage loans (the “Mortgage
        Loans”) secured by one- to four- family residences, units in planned unit
        developments and individual condominium units (the “Trust Fund”) sold by
        DEUTSCHE ALT-A SECURITIES, INC.

       

      THIS
        CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A
        SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE
        TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS
        CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY
        OR
        INSTRUMENTALITY OF THE UNITED STATES.

       

      This
        certifies that [Cede & Co.] is the registered owner of the Percentage
        Interest evidenced hereby in the beneficial ownership interest of Certificates
        of the same Class as this Certificate in certain assets of the Trust Fund
        generally consisting of the Mortgage Loans and related assets sold by Deutsche
        Alt-A Securities, Inc. (the “Depositor”). This Certificate is primarily backed
        by the Group I Loans sold by DB Structured Products, Inc. to the Depositor.
        Wells Fargo Bank, N.A. will act as master servicer of the Mortgage Loans
        (the
“Master Servicer”, which term includes any successors thereto under the
        Agreement referred to below). The Trust Fund was created pursuant to the
        Pooling

        “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer
        and securities administrator (the “Securities Administrator”) and HSBC Bank USA,
        National Association as trustee (the “Trustee”), a summary of certain of the
        pertinent provisions of which is set forth hereafter. To the extent not defined
        herein, capitalized terms used herein shall have the meaning ascribed to
        them in
        the Agreement. This Certificate is issued under and is subject to the terms,
        provisions and conditions of the Agreement, to which Agreement the Holder
        of
        this Certificate by virtue of its acceptance hereof assents and by which
        such
        Holder is bound.

       

      Pursuant
        to the terms of the Agreement, distributions will be made on the 25th
        day of
        each month or, if such 25th
        day is
        not a Business Day, the Business Day immediately following such 25th
        day (a
“Distribution Date”), commencing on the First Distribution Date specified above,
        to the Person in whose name this Certificate is registered at the close of
        business on the Business Day prior to the related Distribution Date (the
“Record
        Date”), in an amount equal to the product of the Percentage Interest evidenced
        by this Certificate and the amount required to be distributed to the Holders
        of
        Class I-A-[1][2][3][4] Certificates on such Distribution Date pursuant to
        the
        Agreement.

       

      All
        distributions to the Holder of this Certificate under the Agreement will
        be made
        or caused to be made by the Securities Administrator by wire transfer in
        immediately available funds to the account of the Person entitled thereto
        if
        such Person shall have so notified the Securities Administrator in writing
        at
        least five Business Days prior to the Record Date immediately prior to such
        Distribution Date and is the registered owner of Class I-A-[1][2][3][4]
        Certificates or otherwise by check mailed by first class mail to the address
        of
        the Person entitled thereto, as such name and address shall appear on the
        Certificate Register. Notwithstanding the above, the final distribution on
        this
        Certificate will be made after due notice by the Securities Administrator
        of the
        pendency of such distribution and only upon presentation and surrender of
        this
        Certificate at the office or agency appointed by the Securities Administrator
        for that purpose as provided in the Agreement.

       

      The
        Pass-Through Rate with respect to the first Distribution Date is equal to
        [_____]% per annum and with respect to any Distribution Date thereafter shall
        be
        a rate per annum (adjusted for the actual number of days which have elapsed
        in
        the related Interest Accrual Period) equal to the lesser of (i) One Month
        LIBOR
        plus [____]% per annum, in the case of each Distribution Date through and
        including the Optional Termination Date, or One-Month LIBOR plus [____]%,
        in the
        case of any Distribution Date following the Optional Termination Date and
        (ii)
        the applicable Net WAC Pass-Through Rate for such Distribution
        Date.

       

      This
        Certificate is one of a duly authorized issue of Certificates designated
        as
        Mortgage Pass-Through Certificate of the Series specified on the face hereof
        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        in the
        Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the related Mortgage Loans and payments received pursuant
        to the Group I Swap Agreement, all as more specifically set forth herein
        and in
        the Agreement. As provided in the Agreement, withdrawals from the Protected
        Accounts and the Distribution Account may be made from time to time for purposes
        other than distributions to Certificateholders, such purposes including
        reimbursement of advances made, or certain expenses incurred, with respect
        to
        the Mortgage Loans. 

       

      The
        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,
        the
        Master Servicer, the Trustee, the Securities Administrator and the rights
        of the
        Certificateholders under the Agreement at any time by the Depositor, the
        Master
        Servicer, the Trustee and the Securities Administrator with the consent of
        the
        Holders of Certificates evidencing, in the aggregate, not less than 66-2/3%
        Percentage Interests of all Certificates (and with respect to matters affecting
        the Group I Swap Agreement, the Group I Swap Provider). Any such consent
        by the
        Holder of this Certificate shall be conclusive and binding on such Holder
        and
        upon all future Holders of this Certificate and of any Certificate issued
        upon
        the transfer hereof or in exchange herefor or in lieu hereof whether or not
        notation of such consent is made upon this Certificate. The Agreement also
        permits the amendment thereof, in certain limited circumstances, without
        the
        consent of the Holders of any of the Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      Prior
        to
        the termination of the Supplemental Interest Trust, any transfer of this
        Certificate to a Plan subject to ERISA or Section 4975 of the Code, any Person
        acting, directly or indirectly, on behalf of any such Plan or any person
        using
        Plan Assets to acquire this Certificate by its acceptance thereof shall be
        deemed to make the representations in Section 5.2(c) of the
        Agreement.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the

        such
        Holder is bound.

       

      Pursuant
        to the terms of the Agreement, distributions will be made on the 25th
        day of
        each month or, if such 25th

        day (a
“Distribution Date”), commencing on the First Distribution Date specified above,
        to the Person in whose name this Certificate is registered at the close of
        business on the last Business Day of the month immediately preceding the

        to the
        Agreement.

       

      All

        be made
        or caused to be made by the Securities Administrator by wire transfer in
        immediately available funds to the account of the Person entitled thereto
        if

        Certificate Register. Notwithstanding the above, the final distribution on
        this
        Certificate will be made after due notice by the Securities Administrator
        of the
        pendency of such distribution and only upon presentation and surrender of
        this
        Certificate at the office or agency appointed by the Securities Administrator
        for that purpose as provided in the Agreement.

       

      The
        Pass-Through Rate with respect to the first Distribution Date is equal to
        [______]% per annum and with respect to any Distribution Date thereafter
        shall
        be a rate per annum equal to the weighted average of the Net Mortgage Rate
        of

        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        in the
        Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the related Mortgage Loans, all as more specifically
        set
        forth herein and in the Agreement. As provided in the Agreement, withdrawals
        from the Protected Accounts and the Distribution Account may be made from
        time
        to time for purposes other than distributions to Certificateholders, such
        purposes including reimbursement of advances made, or certain expenses incurred,
        with respect to the Mortgage Loans.

        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,

        Holders of this Certificate and of any Certificate issued upon the transfer
        hereof or in exchange herefor or in lieu hereof whether or not notation of
        such

        thereof, in certain limited circumstances, without the consent of the Holders
        of
        any of the Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assumes any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator, by manual signature, this Certificate shall not be entitled
        to
        any benefit under the Agreement or be valid for any purpose.

        to the terms of the Agreement, distributions will be made on the 25th
        day of
        each month or, if such 25th
        day is
        not a Business Day, the Business Day immediately following such 25th
        day (a
“Distribution Date”), commencing on the First Distribution Date specified above,
        to the Person in whose name this Certificate is registered at the close of
        business on the Business Day prior to the related Distribution Date (the
“Record
        Date”), in an amount equal to the product of the Percentage Interest evidenced
        by this Certificate and the amount required to be distributed to the Holders
        of
        Class I-M-[1][2][3][4][5][6][7][8] Certificates on such Distribution Date
        pursuant to the Agreement.

       

      All
        distributions to the Holder of this Certificate under the Agreement will
        be made
        or caused to be made by the Securities Administrator by wire transfer in
        immediately available funds to the account of the Person entitled thereto
        if
        such Person shall have so notified the Securities Administrator in writing
        at
        least five Business Days prior to the Record Date immediately prior to such
        Distribution Date and is the registered owner of Class
        I-M-[1][2][3][4][5][6][7][8] Certificates, or otherwise by check mailed by
        first
        class mail to the address of the Person entitled thereto, as such name and
        address shall appear on the Certificate Register. Notwithstanding the above,
        the
        final distribution on this Certificate will be made after due notice by the
        Securities Administrator of the pendency of such distribution and only upon
        presentation and surrender of this Certificate at the office or agency appointed
        by the Securities Administrator for that purpose as provided in the
        Agreement.

       

      The
        Pass-Through Rate with respect to the first Distribution Date is equal to
        [_____]% per annum and with respect to any Distribution Date thereafter shall
        be
        a rate per annum (adjusted for the actual number of days which have elapsed
        in
        the related Interest Accrual Period) equal to the lesser of (i) One Month
        LIBOR
        plus [____]% per annum, in the case of each Distribution Date through and
        including the Optional Termination Date, or One-Month LIBOR plus [____]%,
        in the
        case of any Distribution Date following the Optional Termination Date and
        (ii)
        the applicable Net WAC Pass-Through Rate for such Distribution
        Date.

       

      This
        Certificate is one of a duly authorized issue of Certificates designated
        as
        Mortgage Pass-Through Certificate of the Series specified on the face hereof
        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        interest in the Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the related Mortgage Loans and payments received pursuant
        to the Group I Swap Agreement, all as more specifically set forth herein
        and in
        the Agreement. As provided in the Agreement, withdrawals from the Protected
        Accounts and the Distribution Account may be made from time to time for purposes
        other than distributions to Certificateholders, such purposes including
        reimbursement of advances made, or certain expenses incurred, with respect
        to
        the Mortgage Loans. 

       

      The
        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,
        the
        Master Servicer, the Trustee, the Securities Administrator and the rights
        of the
        Certificateholders under the Agreement at any time by the Depositor, the
        Master
        Servicer, the Trustee and the Securities Administrator with the consent of
        the
        Holders of Certificates evidencing, in the aggregate, not less than 66-2/3%
        Percentage Interests of all Certificates (and with respect to matters affecting
        the Group I Swap Agreement, the Group I Swap Provider). Any such consent
        by the
        Holder of this Certificate shall be conclusive and binding on such Holder
        and
        upon all future Holders of this Certificate and of any Certificate issued
        upon
        the transfer hereof or in exchange herefor or in lieu hereof whether or not
        notation of such consent is made upon this Certificate. The Agreement also
        permits the amendment thereof, in certain limited circumstances, without
        the
        consent of the Holders of any of the Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      Any
        transferee of this Certificate shall be deemed to make the representations
        set
        forth in Section 5.2(c) of the Agreement.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assumes any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator by manual signature, this Certificate shall not be entitled
        to any
        benefit under the Agreement or be valid for any purpose.

        to be
        duly executed.

        PASS-THROUGH CERTIFICATE

       

      evidencing
        a fractional undivided interest in the distributions allocable to the Class
        M
        Certificates with respect to a trust fund generally consisting of a pool
        of
        conventional one- to four-family adjustable-rate mortgage loans (the “Mortgage
        Loans”) secured by one- to four- family residences, units in planned unit
        developments and individual condominium units (the “Trust Fund”) sold by
        DEUTSCHE ALT-A SECURITIES, INC.

       

      THIS
        CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A
        SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE
        TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS
        CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY
        OR
        INSTRUMENTALITY OF THE UNITED STATES.

       

      This
        certifies that [Cede & Co.] is the registered owner of the Percentage
        Interest evidenced hereby in the beneficial ownership interest of Certificates
        of the same Class as this Certificate in certain assets of the Trust Fund
        generally consisting of the Mortgage Loans and related assets sold by Deutsche
        Alt-A Securities, Inc. (the “Depositor”). The Mortgage Loans were sold by DB
        Structured Products, Inc. to the Depositor. Wells Fargo Bank, N.A. will act
        as
        master servicer of the Mortgage Loans (the “Master Servicer”, which term
        includes any successors thereto under the Agreement referred to below). The
        Trust Fund was created pursuant to the Pooling and Servicing Agreement dated
        as
        of the Cut-Off Date specified above (the “Agreement”), among the Depositor,
        Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the
        “Securities Administrator”) and HSBC Bank USA, National Association as trustee
        (the “Trustee”), a summary of certain of the pertinent provisions of which is
        set forth hereafter. To the extent not defined herein, capitalized terms
        used
        herein shall have the meaning ascribed to them in the Agreement. This
        Certificate is issued under and is subject to the terms, provisions and
        conditions of the Agreement, to which Agreement the Holder of this Certificate
        by virtue of its acceptance hereof assents and by which such Holder is
        bound.

       

      Pursuant
        to the terms of the Agreement, distributions will be made on the 25th
        day of
        each month or, if such 25th
        day is
        not a Business Day, the Business Day immediately following such 25th
        day (a
“Distribution Date”), commencing on the First Distribution Date specified above,
        to the Person in whose name this Certificate is registered at the close of
        business on the last Business Day of the month immediately preceding the
        month
        in which such Distribution Date occurs (the “Record Date”), in an amount equal
        to the product of the Percentage Interest evidenced by this Certificate and
        the
        amount required to be distributed to the Holders of Class M Certificates
        on such
        Distribution Date pursuant to the Agreement.

       

      All
        distributions to the Holder of this Certificate under the Agreement will
        be made
        or caused to be made by the Securities Administrator by wire transfer in
        immediately available funds to the account of the Person entitled thereto
        if
        such Person shall have so notified the Securities Administrator in writing
        at
        least five Business Days prior to the Record Date immediately prior to such
        Distribution Date and is the registered owner of Class M Certificates, or
        otherwise by check mailed by first class mail to the address of the Person
        entitled thereto, as such name and address shall appear on the Certificate
        Register. Notwithstanding the above, the final distribution on this Certificate
        will be made after due notice by the Securities Administrator of the pendency
        of
        such distribution and only upon presentation and surrender of this Certificate
        at the office or agency appointed by the Securities Administrator for that
        purpose as provided in the Agreement.

       

      The
        Pass-Through Rate with respect to the first Distribution Date is equal to
        [______]% per annum and with respect to any Distribution Date thereafter
        shall
        be a rate per annum equal to (1) the sum of the following for each loan group:
        the product of (x) the weighted average net mortgage rate of the related
        Mortgage Loans and (y) the Subordinate Amount immediately prior to that
        Distribution Date, divided by (2) the aggregate certificate principal balance
        of
        the Group II-V Subordinate Certificates immediately prior to that Distribution
        Date.

       

      This
        Certificate is one of a duly authorized issue of Certificates designated
        as a
        Mortgage Pass-Through Certificate of the Series specified on the face hereof
        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        interest in the Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the Mortgage Loans, all as more specifically set forth
        herein and in the Agreement. As provided in the Agreement, withdrawals from
        the
        Protected Accounts and the Distribution Account may be made from time to
        time
        for purposes other than distributions to Certificateholders, such purposes
        including reimbursement of advances made, or certain expenses incurred, with
        respect to the Mortgage Loans. 

       

      The
        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,
        the
        Master Servicer, the Trustee, the Securities Administrator and the rights
        of the
        Certificateholders under the Agreement at any time by the Depositor, the
        Master
        Servicer, the Trustee and the Securities Administrator with the consent of
        the
        Holders of Certificates evidencing, in the aggregate, not less than 66-2/3%
        Percentage Interests of all Certificates. Any such consent by the Holder
        of this
        Certificate shall be conclusive and binding on such Holder and upon all future
        Holders of this Certificate and of any Certificate issued upon the transfer
        hereof or in exchange herefor or in lieu hereof whether or not notation of
        such
        consent is made upon this Certificate. The Agreement also permits the amendment
        thereof, in certain limited circumstances, without the consent of the Holders
        of
        any of the Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      Any
        transferee of this Certificate shall be deemed to make the representations
        set
        forth in Section 5.2(c) of the Agreement.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assume any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator by manual signature, this Certificate shall not be entitled
        to any
        benefit under the Agreement or be valid for any purpose.

          WITNESS WHEREOF, the Securities Administrator has caused this Certificate
          to be
          duly executed.

      evidencing
        a fractional undivided interest in the distributions allocable to the Class
        B-[1][2] Certificates with respect to a trust fund generally consisting of
        a
        pool of conventional one- to four-family adjustable-rate mortgage loans (the

        unit developments and individual condominium units (the “Trust Fund”) sold by
        DEUTSCHE ALT-A SECURITIES, INC.

       

      THIS
        CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A
        SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE

        OR
        INSTRUMENTALITY OF THE UNITED STATES.

       

      This

        of the same Class as this Certificate in certain assets of the Trust Fund
        generally consisting of the Mortgage Loans and related assets sold by Deutsche
        Alt-A Securities, Inc. (the “Depositor”). The Mortgage Loans were sold by DB
        Structured Products, Inc. to the Depositor. Wells Fargo Bank, N.A. will act
        as
        master servicer of the Mortgage Loans (the “Master Servicer”, which term
        includes any successors thereto under the Agreement referred to below). The
        Trust Fund was created pursuant to the Pooling and Servicing Agreement dated

        Certificate is issued under and is subject to the terms, provisions and
        conditions of the Agreement, to which Agreement the Holder of this Certificate
        by virtue of its acceptance hereof assents and by which such Holder is
        bound.

       

      Pursuant
        to the terms of the Agreement, distributions will be made on the 25th day
        of
        each month or, if such 25th day is not a Business Day, the Business Day
        immediately following such 25th day (a “Distribution Date”), commencing on the
        First Distribution Date specified above, to the Person in whose name this
        Certificate is registered at the close of business on the last Business Day
        of
        the month immediately preceding the month in which such Distribution Date
        occurs
        (the “Record Date”), in an amount equal to the product of the Percentage
        Interest evidenced by this Certificate and the amount required to be distributed
        to the Holders of Class B-[1][2] Certificates on such Distribution Date pursuant
        to the Agreement.

       

      All
        distributions to the Holder of this Certificate under the Agreement will
        be made
        or caused to be made by the Securities Administrator by wire transfer in
        immediately available funds to the account of the Person entitled thereto
        if
        such Person shall have so notified the Securities Administrator in writing
        at
        least five Business Days prior to the Record Date immediately prior to such
        Distribution Date and is the registered owner of Class B-[1][2] Certificates,
        or
        otherwise by check mailed by first class mail to the address of the Person
        entitled thereto, as such name and address shall appear on the Certificate
        Register. Notwithstanding the above, the final distribution on this Certificate
        will be made after due notice by the Securities Administrator of the pendency
        of
        such distribution and only upon presentation and surrender of this Certificate
        at the office or agency appointed by the Securities Administrator for that
        purpose as provided in the Agreement.

       

      The
        Pass-Through Rate with respect to the first Distribution Date is equal to
        [______]% per annum and with respect to any Distribution Date thereafter
        shall
        be a rate per annum equal to (1) the sum of the following for each loan group:
        the product of (x) the weighted average net mortgage rate of the related
        Mortgage Loans and (y) the Subordinate Amount immediately prior to that
        Distribution Date, divided by (2) the aggregate certificate principal balance
        of
        the Group II-V Subordinate Certificates immediately prior to that Distribution
        Date.

       

      This
        Certificate is one of a duly authorized issue of Certificates designated
        as a
        Mortgage Pass-Through Certificate of the Series specified on the face hereof
        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        interest in the Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the Mortgage Loans, all as more specifically set forth
        herein and in the Agreement. As provided in the Agreement, withdrawals from
        the
        Protected Accounts and the Distribution Account may be made from time to
        time
        for purposes other than distributions to Certificateholders, such purposes
        including reimbursement of advances made, or certain expenses incurred, with
        respect to the Mortgage Loans. 

       

      The
        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,
        the
        Master Servicer, the Trustee, the Securities Administrator and the rights
        of the
        Certificateholders under the Agreement at any time by the Depositor, the
        Master
        Servicer, the Trustee and the Securities Administrator with the consent of
        the
        Holders of Certificates evidencing, in the aggregate, not less than 66-2/3%
        Percentage Interest of all Certificates. Any such consent by the Holder of
        this
        Certificate shall be conclusive and binding on such Holder and upon all future
        Holders of this Certificate and of any Certificate issued upon the transfer
        hereof or in exchange herefor or in lieu hereof whether or not notation of
        such
        consent is made upon this Certificate. The Agreement also permits the amendment
        thereof, in certain limited circumstances, without the consent of the Holders
        of
        any of the Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      Any
        transferee of this Certificate shall be deemed to make the representations
        set
        forth in Section 5.2(c) of the Agreement.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assume any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator, by manual signature, this Certificate shall not be entitled
        to
        any benefit under the Agreement or be valid for any purpose.

        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      No
        transfer of this Certificate shall be made unless the transfer is made pursuant
        to an effective registration statement under the Securities Act, and an
        effective registration or qualification under applicable state securities
        laws,
        or is made in a transaction that does not require such registration or
        qualification. In the event that such a transfer of this Certificate is to
        be
        made without registration or qualification, the Securities Administrator
        shall
        require receipt of (i) if such transfer is purportedly being made in reliance
        upon Rule 144A or Regulation S under the Securities Act, written certifications
        from the Holder of the Certificate desiring to effect the transfer, and from
        such Holder’s prospective transferee, substantially in the forms attached to the
        Agreement as Exhibits B-1 and B-3, respectively, (ii) if such transfer is
        purportedly being made in reliance upon Rule 501(a) under the Securities
        Act,
        written certifications from the Holder of the Certificate desiring to effect
        the
        transfer and from such Holder’s prospective transferee, substantially in the
        form attached to the Agreement as Exhibit B-2 and (iii) in all other cases,
        an
        Opinion of Counsel satisfactory to it that such transfer may be made without
        such registration or qualification (which Opinion of Counsel shall not be
        an
        expense of the Trust Fund or of the Depositor, the Trustee, the Master Servicer
        or the Securities Administrator in their respective capacities as such),
        together with copies of the written certification(s) of the Holder of the
        Certificate desiring to effect the transfer and/or such Holder’s prospective
        transferee upon which such Opinion of Counsel is based. None of the Depositor,
        the Trustee or the Securities Administrator is obligated to register or qualify
        the Class of Certificates specified on the face hereof under the Securities
        Act
        or any other securities law or to take any action not otherwise required
        under
        the Agreement to permit the transfer of such Certificates without registration
        or qualification. Any Holder desiring to effect a transfer of this Certificate
        shall be required to indemnify the Trustee, the Depositor, the Master Servicer
        and the Securities Administrator against any liability that may result if
        the
        transfer is not so exempt or is not made in accordance with such federal
        and
        state laws.

       

      No
        transfer of this Certificate shall be made to any person unless the Transferee
        provides a certification pursuant to Section 5.2(c) of the Agreement.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assume any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator, by manual signature, this Certificate shall not be entitled
        to
        any benefit under the Agreement or be valid for any purpose.

      This

        the
        Percentage Interest evidenced hereby in the beneficial ownership interest
        of

        Trust Fund generally consisting of the Mortgage Loans and related assets
        sold by
        Deutsche Alt-A Securities, Inc. (the “Depositor”). The Mortgage Loans were sold
        by DB Structured Products, Inc. to the Depositor. Wells Fargo Bank, N.A.
        will
        act as master servicer of the Mortgage Loans (the “Master Servicer”, which term
        includes any successors thereto under the Agreement referred to below). The

        as
        of the Cut-Off Date specified above (the “Agreement”), among the Depositor,
        Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the
        “Securities Administrator”) and HSBC Bank USA, National Association as trustee
        (the “Trustee”), a summary of certain of the pertinent provisions of which is
        set forth hereafter. To the extent not defined herein, capitalized terms
        used
        herein shall have the meaning ascribed to them in the Agreement. This
        Certificate is issued under and is subject to the terms, provisions and
        conditions of the Agreement, to which Agreement the Holder of this Certificate
        by virtue of its acceptance hereof assents and by which such Holder is
        bound.

       

      Pursuant
        to the terms of the Agreement, distributions will be made on the 25th
        day of
        each month or, if such 25th
        day is
        not a Business Day, the Business Day immediately following such 25th
        day (a
“Distribution Date”), commencing on the First Distribution Date specified above,
        to the Person in whose name this Certificate is registered at the close of
        business on the last Business Day of the month immediately preceding the
        month
        in which such Distribution Date occurs (the “Record Date”), in an amount equal
        to the product of the Percentage Interest evidenced by this Certificate and
        the
        amount required to be distributed to the Holders of Class [I-R][A-R]
        Certificates on such Distribution Date pursuant to the Agreement.

       

      All
        distributions to the Holder of this Certificate under the Agreement will
        be made
        or caused to be made by the Securities Administrator by wire transfer in
        immediately available funds to the account of the Person entitled thereto
        if
        such Person shall have so notified the Securities Administrator in writing
        at
        least five Business Days prior to the Record Date immediately prior to such
        Distribution Date and is the registered owner of Class [I-R][A-R] Certificates,
        or otherwise by check mailed by first class mail to the address of the Person
        entitled thereto, as such name and address shall appear on the Certificate
        Register. Notwithstanding the above, the final distribution on this Certificate
        will be made after due notice by the Securities Administrator of the pendency
        of
        such distribution and only upon presentation and surrender of this Certificate
        at the office or agency appointed by the Securities Administrator for that
        purpose as provided in the Agreement.

       

      The
        Pass-Through Rate with respect to the first Distribution Date is equal to
        [____]% per annum and with respect to any Distribution Date thereafter shall
        be
        equal to the weighted average of the Net Mortgage Rates of the Group [I][II-V]
        Loans for such Distribution Date.

       

      This
        Certificate is one of a duly authorized issue of Certificates designated
        as
        Mortgage Pass-Through Certificate of the Series specified on the face hereof
        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        interest in the Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the Mortgage Loans [and payments received pursuant
        to the
        Group I Swap Agreement], all as more specifically set forth herein and in
        the
        Agreement. As provided in the Agreement, withdrawals from the Protected Accounts
        and the Distribution Account may be made from time to time for purposes other
        than distributions to Certificateholders, such purposes including reimbursement
        of advances made, or certain expenses incurred, with respect to the Mortgage
        Loans. 

       

      The
        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,
        the
        Master Servicer, the Trustee, the Securities Administrator and the rights
        of the
        Certificateholders under the Agreement at any time by the Depositor, the
        Master
        Servicer, the Trustee and the Securities Administrator with the consent of
        the
        Holders of Certificates evidencing, in the aggregate, not less than 66-2/3%
        Percentage Interest of all Certificates [(and with respect to matters affecting
        the Group I Swap Agreement, the Group I Swap Provider).] Any such consent
        by the
        Holder of this Certificate shall be conclusive and binding on such Holder
        and
        upon all future Holders of this Certificate and of any Certificate issued
        upon
        the transfer hereof or in exchange herefor or in lieu hereof whether or not
        notation of such consent is made upon this Certificate. The Agreement also
        permits the amendment thereof, in certain limited circumstances, without
        the
        consent of the Holders of any of the Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, Certificates are exchangeable for new Certificates of
        the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      Each
        Holder of this Certificate will be deemed to have agreed to be bound by the
        restrictions set forth in the Agreement to the effect that (i) each person
        holding or acquiring any Ownership Interest in this Certificate must be a
        United
        States Person and a Permitted Transferee, (ii) the transfer of any Ownership
        Interest in this Certificate will be conditioned upon the delivery to the
        Securities Administrator of, among other things, an affidavit to the effect
        that
        it is a United States Person and Permitted Transferee, (iii) any attempted
        or
        purported transfer of any Ownership Interest in this Certificate in violation
        of
        such restrictions will be absolutely null and void and will vest no rights
        in
        the purported transferee, and (iv) if any person other than a United States
        Person and a Permitted Transferee acquires any Ownership Interest in this
        Certificate in violation of such restrictions, then the Depositor will have
        the
        right, in its sole discretion and without notice to the Holder of this
        Certificate, to sell this Certificate to a purchaser selected by the Depositor,
        which purchaser may be the Depositor, or any affiliate of the Depositor,
        on such
        terms and conditions as the Depositor may choose.

       

      No
        transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
        the
        Code, any Person acting, directly or indirectly, on behalf of any such Plan
        or
        any Person using “Plan Assets” to acquire this Certificate shall be made except
        in accordance with Section 5.2(c) of the Agreement.

       

      Prior
        to
        registration of any transfer, sale or other disposition of this Certificate,
        the
        proposed transferee shall provide to the Securities Administrator (i) an
        affidavit to the effect that such transferee is any Person other than a
        Disqualified Organization or the agent (including a broker, nominee or
        middleman) of a Disqualified Organization, and (ii) a certificate that
        acknowledges that (A) the Class [I-R][A-R] Certificates have been designated
        as
        representing the beneficial ownership of the residual interests in each REMIC,
        (B) it will include in its income a pro
        rata
        share of
        the net income of the Trust Fund and that such income may be an “excess
        inclusion,” as defined in the Code, that, with certain exceptions, cannot be
        offset by other losses or benefits from any tax exemption, and (C) it expects
        to
        have the financial means to satisfy all of its tax obligations including
        those
        relating to holding the Class [I-R][A-R] Certificates. Notwithstanding the
        registration in the Certificate Register of any transfer, sale or other
        disposition of this Certificate to a Disqualified Organization or an agent
        (including a broker, nominee or middleman) of a Disqualified Organization,
        such
        registration shall be deemed to be of no legal force or effect whatsoever
        and
        such Person shall not be deemed to be a Certificateholder for any purpose,
        including, but not limited to, the receipt of distributions in respect of
        this
        Certificate.

       

      The
        Holder of this Certificate, by its acceptance hereof, shall be deemed to
        have
        consented to the provisions of Section 5.2(c) of the Agreement and to any
        amendment of the Agreement deemed necessary by counsel of the Depositor to
        ensure that the transfer of this Certificate to any Person other than a
        Permitted Transferee or any other Person will not cause any portion of the
        Trust
        Fund to cease to qualify as a REMIC or cause the imposition of a tax upon
        any
        REMIC.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assume any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator, by manual signature, this Certificate shall not be entitled
        to
        any benefit under the Agreement or be valid for any purpose.

      

        
          
            
            

          

          
            
            

            
              

            

          

          
            
            

          

        

      

       

      
        IN
          WITNESS WHEREOF, the Securities Administrator has caused this Certificate
          to be
          duly executed.

        conditions of the Agreement, to which Agreement the Holder of this Certificate
        by virtue of its acceptance hereof assents and by which such Holder is
        bound.

       

      Pursuant
        to the terms of the Agreement, distributions will be made on the 25th day
        of

        First Distribution Date specified above, to the Person in whose name this
        Certificate is registered at the close of business on the last Business Day

        Register. Notwithstanding the above, the final distribution on this Certificate
        will be made after due notice by the Securities Administrator of the pendency
        of
        such distribution and only upon presentation and surrender of this Certificate
        at the office or agency appointed by the Securities Administrator for that
        purpose as provided in the Agreement.

       

      This
        Certificate is one of a duly authorized issue of Certificates designated
        as
        Mortgage Pass-Through Certificate of the Series specified on the face hereof
        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        interest in the Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the Mortgage Loans, all as more specifically set forth
        herein and in the Agreement. As provided in the Agreement, withdrawals from
        the
        Protected Accounts and the Distribution Account may be made from time to
        time
        for purposes other than distributions to Certificateholders, such purposes
        including reimbursement of advances made, or certain expenses incurred, with
        respect to the Mortgage Loans. 

       

      The
        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,
        the
        Master Servicer, the Trustee, the Securities Administrator, the Servicers
        and
        the rights of the Certificateholders under the Agreement at any time by the
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        the Servicers with the consent of the Holders of Certificates entitled to
        at
        least 66% of the Voting Rights (and with respect to matters affecting the
        Group
        I Swap Agreement, the Group I Swap Provider). Any such consent by the Holder
        of
        this Certificate shall be conclusive and binding on such Holder and upon
        all
        future Holders of this Certificate and of any Certificate issued upon the
        transfer hereof or in exchange herefor or in lieu hereof whether or not notation
        of such consent is made upon this Certificate. The Agreement also permits
        the
        amendment thereof, in certain limited circumstances, without the consent
        of the
        Holders of any of the Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same.

       

      No
        service charge will be made for any such registration of transfer or exchange
        of
        Certificates, but the Securities Administrator may require payment of a sum
        sufficient to cover any tax or other governmental charge that may be imposed
        in
        connection with any transfer or exchange of Certificates.

       

      No
        transfer of this Certificate shall be made unless the transfer is made pursuant
        to an effective registration statement under the Securities Act, and an
        effective registration or qualification under applicable state securities
        laws,
        or is made in a transaction that does not require such registration or
        qualification. In the event that such a transfer of this Certificate is to
        be
        made without registration or qualification, the Securities Administrator
        shall
        require receipt of (i) if such transfer is purportedly being made in reliance
        upon Rule 144A or Regulation S under the Securities Act, written certifications
        from the Holder of the Certificate desiring to effect the transfer, and from
        such Holder’s prospective transferee, substantially in the forms attached to the
        Agreement as Exhibits B-1 and B-3, respectively, (ii) if such transfer is
        purportedly being made in reliance upon Rule 501(a) under the Securities
        Act,
        written certifications from the Holder of the Certificate desiring to effect
        the
        transfer and from such Holder’s prospective transferee, substantially in the
        form attached to the Agreement as Exhibit B-2 and (iii) in all other cases,
        an
        Opinion of Counsel satisfactory to it that such transfer may be made without
        such registration or qualification (which Opinion of Counsel shall not be
        an
        expense of the Trust Fund or of the Depositor, the Trustee, the Master Servicer
        or the Securities Administrator in their respective capacities as such),
        together with copies of the written certification(s) of the Holder of the
        Certificate desiring to effect the transfer and/or such Holder’s prospective
        transferee upon which such Opinion of Counsel is based. None of the Depositor,
        the Trustee or the Securities Administrator is obligated to register or qualify
        the Class of Certificates specified on the face hereof under the Securities
        Act
        or any other securities law or to take any action not otherwise required
        under
        the Agreement to permit the transfer of such Certificates without registration
        or qualification. Any Holder desiring to effect a transfer of this Certificate
        shall be required to indemnify the Trustee, the Depositor, the Master Servicer
        and the Securities Administrator against any liability that may result if
        the
        transfer is not so exempt or is not made in accordance with such federal
        and
        state laws.

       

      No
        transfer of this Certificate shall be made to any person unless the Transferee
        provides a certification pursuant to Section 5.2(c) of the Agreement.

       

      No
        transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
        the
        Code, any Person acting, directly or indirectly, on behalf of any such Plan
        or
        any Person using “Plan Assets” to acquire this Certificate shall be made except
        in accordance with Section 5.2(c) of the Agreement.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee or the Securities Administrator nor any such agent
        shall
        be affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assume any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator, by manual signature, this Certificate shall not be entitled
        to
        any benefit under the Agreement or be valid for any purpose.

        by virtue of its acceptance hereof assents and by which such Holder is
        bound.

       

      Pursuant
        to the terms of the Agreement, distributions will be made on the 25th
        day of
        each month or, if such 25th
        day is
        not a Business Day, the Business Day immediately following such 25th
        day (a
“Distribution Date”), commencing on the First Distribution Date specified above,
        to the Person in whose name this Certificate is registered at the close of
        business on the last Business Day of the month immediately preceding the
        month
        in which such Distribution Date occurs (the “Record Date”), in an amount equal
        to the product of the Percentage Interest evidenced by this Certificate and
        the
        amount required to be distributed to the Holders of Class [I][II/V]-P-[1][2]
        Certificates on such Distribution Date pursuant to the Agreement.

       

      All
        distributions to the Holder of this Certificate under the Agreement will
        be made
        or caused to be made by the Securities Administrator by wire transfer in
        immediately available funds to the account of the Person entitled thereto
        if
        such Person shall have so notified the Securities Administrator in writing
        at
        least five Business Days prior to the Record Date immediately prior to such
        Distribution Date and is the registered owner of Class [I][II/V]-P-[1][2]
        Certificates the aggregate initial Certificate Principal Balance of which
        is in
        excess of the lesser of (i) $5,000,000 or (ii) two-thirds of the aggregate
        initial Certificate Principal Balance of the Class [I][II/V]-P-[1][2]
        Certificates, or otherwise by check mailed by first class mail to the address
        of
        the Person entitled thereto, as such name and address shall appear on the
        Certificate Register. Notwithstanding the above, the final distribution on
        this
        Certificate will be made after due notice by the Securities Administrator
        of the
        pendency of such distribution and only upon presentation and surrender of
        this
        Certificate at the office or agency appointed by the Securities Administrator
        for that purpose as provided in the Agreement.

       

      This
        Certificate is one of a duly authorized issue of Certificates designated
        as
        Mortgage Pass-Through Certificate of the Series specified on the face hereof
        (herein called the “Certificates”) and representing a Percentage Interest in the
        Class of Certificates specified on the face hereof equal to the denomination
        specified on the face hereof divided by the aggregate Certificate Principal
        Balance of the Class of Certificates specified on the face hereof. The
        Certificates, in the aggregate, evidence the entire beneficial ownership
        interest in the Trust Fund formed pursuant to the Agreement.

       

      The
        Certificates are limited in right of payment to certain collections and
        recoveries respecting the Mortgage Loans and certain other assets of the
        Trust
        Fund, all as more specifically set forth herein and in the Agreement. As
        provided in the Agreement, withdrawals from the Protected Accounts and the
        Distribution Account may be made from time to time for purposes other than
        distributions to Certificateholders, such purposes including reimbursement
        of
        advances made, or certain expenses incurred, with respect to the Mortgage
        Loans.

       

      The
        Agreement permits, with certain exceptions therein provided, the amendment
        thereof and the modification of the rights and obligations of the Depositor,
        the
        Master Servicer, the Trustee, the Securities Administrator, and the rights
        of
        the Certificateholders under the Agreement at any time by the Depositor,
        the
        Master Servicer, the Trustee and the Securities Administrator with the consent
        of the Holders of Certificates entitled to at least 66% of the Voting Rights.
        Any such consent by the Holder of this Certificate shall be conclusive and
        binding on such Holder and upon all future Holders of this Certificate and
        of
        any Certificate issued upon the transfer hereof or in exchange herefor or
        in
        lieu hereof whether or not notation of such consent is made upon this
        Certificate. The Agreement also permits the amendment thereof, in certain
        limited circumstances, without the consent of the Holders of any of the
        Certificates.

       

      As
        provided in the Agreement and subject to certain limitations therein set
        forth,
        the transfer of this Certificate is registrable in the Certificate Register
        upon
        surrender of this Certificate for registration of transfer at the offices
        or
        agencies appointed by the Securities Administrator as provided in the Agreement,
        duly endorsed by, or accompanied by an assignment in the form below or other
        written instrument of transfer in form satisfactory to the Securities
        Administrator duly executed by, the Holder hereof or such Holder’s attorney duly
        authorized in writing, and thereupon one or more new Certificates of the
        same
        Class in authorized denominations evidencing the same aggregate Percentage
        Interest will be issued to the designated transferee or
        transferees.

       

      The
        Certificates are issuable in fully registered form only without coupons in
        Classes and denominations representing Percentage Interests specified in
        the
        Agreement. As provided in the Agreement and subject to certain limitations
        therein set forth, the Certificates are exchangeable for new Certificates
        of the
        same Class in authorized denominations evidencing the same aggregate Percentage
        Interest, as requested by the Holder surrendering the same. No service charge
        will be made for any such registration of transfer or exchange of Certificates,
        but the Securities Administrator may require payment of a sum sufficient
        to
        cover any tax or other governmental charge that may be imposed in connection
        with any transfer or exchange of Certificates.

       

      No
        transfer of this Certificate shall be made unless the transfer is made pursuant
        to an effective registration statement under the Securities Act, and an
        effective registration or qualification under applicable state securities
        laws,
        or is made in a transaction that does not require such registration or
        qualification. In the event that such a transfer of this Certificate is to
        be
        made without registration or qualification, the Securities Administrator
        shall
        require receipt of (i) if such transfer is purportedly being made in reliance
        upon Rule 144A or Regulation S under the Securities Act, written certifications
        from the Holder of the Certificate desiring to effect the transfer, and from
        such Holder’s prospective transferee, substantially in the forms attached to the
        Agreement as Exhibits B-1 and B-3, respectively, (ii) if such transfer is
        purportedly being made in reliance upon Rule 501(a) under the Securities
        Act,
        written certifications from the Holder of the Certificate desiring to effect
        the
        transfer and from such Holder’s prospective transferee, substantially in the
        form attached to the Agreement as Exhibit B-2 and (iii) in all other cases,
        an
        Opinion of Counsel satisfactory to it that such transfer may be made without
        such registration or qualification (which Opinion of Counsel shall not be
        an
        expense of the Trust Fund or of the Depositor, the Trustee, the Master Servicer
        or the Securities Administrator in their respective capacities as such),
        together with copies of the written certification(s) of the Holder of the
        Certificate desiring to effect the transfer and/or such Holder’s prospective
        transferee upon which such Opinion of Counsel is based. None of the Depositor,
        the Trustee or the Securities Administrator is obligated to register or qualify
        the Class of Certificates specified on the face hereof under the Securities
        Act
        or any other securities law or to take any action not otherwise required
        under
        the Agreement to permit the transfer of such Certificates without registration
        or qualification. Any Holder desiring to effect a transfer of this Certificate
        shall be required to indemnify the Trustee, the Depositor, the Master Servicer
        and the Securities Administrator against any liability that may result if
        the
        transfer is not so exempt or is not made in accordance with such federal
        and
        state laws.

       

      No
        transfer of this Certificate to a Plan subject to ERISA or Section 4975 of
        the
        Code, any Person acting, directly or indirectly, on behalf of any such Plan
        or
        any Person using “Plan Assets” to acquire this Certificate shall be made except
        in accordance with Section 5.2(c) of the Agreement.

       

      The
        Depositor, the Master Servicer, the Trustee, the Securities Administrator
        and
        any agent of the Depositor, the Master Servicer, the Trustee or the Securities
        Administrator may treat the Person in whose name this Certificate is registered
        as the owner hereof for all purposes, and none of the Depositor, the Master
        Servicer, the Trustee, the Securities Administrator nor any such agent shall
        be
        affected by notice to the contrary.

       

      The
        obligations created by the Agreement and the Trust Fund created thereby shall
        terminate upon payment to the Certificateholders of all amounts held by the
        Securities Administrator and required to be paid to them pursuant to the
        Agreement following the earlier of (i) the final payment or other liquidation
        (or any advance with respect thereto) of the last Mortgage Loan remaining
        in the
        Trust Fund and (ii) the purchase by the party designated in the Agreement
        at a
        price determined as provided in the Agreement of (A) all of the Group I Loans
        and all property acquired in respect of such Group I Loans, and (B) all of
        the
        Group II-V Loans and all properties acquired in respect of such Group II-V
        Loans. The Agreement permits, but does not require, the party designated
        in the
        Agreement to purchase all the Mortgage Loans and all property acquired in
        respect of any Mortgage Loan at a price determined as provided in the Agreement.
        The exercise of such right will effect early retirement of the Certificates
        relating to the applicable Loan Group; however, such right to purchase is
        subject to the aggregate Scheduled Principal Balance of the Group I Loans
        or the
        Group II-V Loans, as applicable, and the fair market value of each related
        REO
        Property remaining in the Trust Fund at the time of purchase, being less
        than or
        equal to 5% of the aggregate Scheduled Principal Balance of the Group I Loans
        or
        the Group II-V Loans, as applicable, as of the Cut-Off Date.

       

      The
        recitals contained herein shall be taken as statements of the Depositor and
        neither the Trustee nor the Securities Administrator assume any responsibility
        for their correctness.

       

      Unless
        the certificate of authentication hereon has been executed by the Securities
        Administrator, by manual signature, this Certificate shall not be entitled
        to
        any benefit under the Agreement or be valid for any purpose.

      Neither
        the Transferor nor anyone acting on its behalf has (a) offered, pledged,
        sold,
        disposed of or otherwise transferred any Certificate, any interest in any
        Certificate or any other similar security to any person in any manner, (b)
        has
        solicited any offer to buy or to accept a pledge, disposition or other transfer
        of any Certificate, any interest in any Certificate or any other similar
        security from any person in any manner, (c) has otherwise approached or
        negotiated with respect to any Certificate, any interest in any Certificate
        or

        general solicitation by means of general advertising or in any other manner,
        (e)
        has taken any other action, that (in the case of each of subclauses (a) through
        (e) above) would constitute a distribution of the Certificates under the
        Securities Act of 1933, as amended (the “1933 Act”), or would render the
        disposition of any Certificate a violation of Section 5 of the 1933 Act or
        any
        state securities law or would require registration or qualification pursuant
        thereto. The Transferor will not act, nor has it authorized or will it authorize
        any person to act, in any manner set forth in the foregoing sentence with
        respect to any Certificate. The Transferor will not sell or otherwise transfer

      Ladies

      In
        connection with the purchase from ______________________________ (the
“Transferor”) on the date hereof of the captioned trust certificates (the
“Certificates”), (the “Transferee”) hereby certifies as follows:

       

      The
        Transferee is a “qualified institutional buyer” as that term is defined in Rule
        144A (“Rule 144A”) under the Securities Act of 1933 (the “1933 Act”) and has
        completed either of the forms of certification to that effect attached hereto
        as
        Annex 1 or Annex 2. The Transferee is aware that the sale to it is being
        made in
        reliance on Rule 144A. The Transferee is acquiring the Certificates for its
        own
        account or for the account of a qualified institutional buyer, and understands
        that such Certificate may be resold, pledged or transferred only (i) to a
        person
        reasonably believed to be a qualified institutional buyer that purchases
        for its
        own account or for the account of a qualified institutional buyer to whom
        notice
        is given that the resale, pledge or transfer is being made in reliance on
        Rule
        144A, or (ii) pursuant to another exemption from registration under the 1933
        Act.

       

      The
        Transferee has been furnished with all information regarding (a) the
        Certificates and distributions thereon, (b) the nature, performance and
        servicing of the Mortgage Loans, (c) the Pooling and Servicing Agreement
        referred to below, and (d) any credit enhancement mechanism associated with
        the
        Certificates, that it has requested.

       

      The
        Transferee: (a) is not an employee benefit or other plan subject to the
        prohibited transaction provisions of the Employee Retirement Income Security
        Act
        of 1974, as amended (“ERISA), or Section 4975 of the Internal Revenue Code of
        1986, as amended (the “Code”) (each, a “Plan”), or any other person (including
        an investment manager, a named fiduciary or a trustee of any Plan) acting,
        directly or indirectly, on behalf of or purchasing any Certificate with “plan
        assets” of any Plan within the meaning of the Department of Labor (“DOL”)
        regulation at 29 C.F.R. §2510.3-101 or (b) [[for Class I-P1, Class I-P2, Class
        II/V-P1, Class II/V-P2] has provided the Securities Administrator with an
        opinion of counsel on which the Trustee, the Depositor, the Master Servicer
        and
        the Securities Administrator may rely, acceptable to and in form and substance
        satisfactory to the Trustee to the effect that the purchase of Certificates
        is
        permissible under applicable law, will not constitute or result in any
        non-exempt prohibited transaction under ERISA or Section 4975 of the Code
        and
        will not subject the Trust Fund, the Trustee, the Depositor, the Master Servicer
        or the Securities Administrator to any obligation or liability (including
        obligations or liabilities under ERISA or Section 4975 of the Code) in addition
        to those undertaken in the Pooling and Servicing Agreement.] [[for Class
        B-3,
        Class B-4, Class B-5] (i) is an insurance company, (ii) the source of funds
        used
        to acquire or hold the certificate or interest therein is an “insurance company
        general account,” as such term is defined in Prohibited Transaction Class
        Exemption (“PTCE”) 95-60, and (iii) (A) prior to the termination of the
        Supplemental Interest Trust, the acquisition and holding of such Certificate
        and
        the separate right to receive payments from the Supplemental Interest Trust
        are
        eligible for the exemptive relief under PTCE 95-60 and (B) subsequent to
        the
        termination of the Supplemental Interest Trust, the conditions in Sections
        I and
        III of PTCE 95-60 have been satisfied.]

       

      In
        addition, the Transferee hereby certifies, represents and warrants to, and
        covenants with, the Depositor, the Trustee, the Securities Administrator
        and the
        Master Servicer that the Transferee will not transfer such Certificates to
        any
        Plan or person unless such Plan or person meets the requirements set forth in
        paragraph 3 above.

       

      All
        capitalized terms used but not otherwise defined herein have the respective
        meanings assigned thereto in the Pooling and Servicing Agreement (the “Pooling
        and Servicing Agreement”), dated as of January 1, 2006, among Deutsche Alt-A

                Insurance
                  Company.
                  The Transferee is an insurance company whose primary and predominant
                  business activity is the writing of insurance or the reinsuring
                  of risks
                  underwritten by insurance companies and which is subject to supervision
                  by
                  the insurance commissioner or a similar official or agency of a
                  State,
                  territory or the District of
                  Columbia.

              

      

       

      
        	 	
                ___

              	
                State
                  or Local Plan.
                  The Transferee is a plan established and maintained by a State,
                  its
                  political subdivisions, or any agency or instrumentality of the
                  State or
                  its political subdivisions, for the benefit of its
                  employees.

              

      

       

      
        	 	
                ___

              	
                ERISA
                  Plan.
                  The Transferee is an employee benefit plan within the meaning of
                  Title I
                  of the Employee Retirement Income Security Act of
                  1974.

              

      

       

      
        	 	
                ___

              	
                Investment
                  Advisor
                  The Transferee is an investment advisor registered under the Investment
                  Advisers Act of 1940.

              

      

       

      3. The
        term
“securities”
        as used
        herein does
        not include
        (i)
        securities of issuers that are affiliated with the Transferee, (ii) securities
        that are part of an unsold allotment to or subscription by the Transferee,
        if
        the Transferee is a dealer, (iii) securities issued or guaranteed by the
        U.S. or
        any instrumentality thereof, (iv) bank deposit notes and certificates of
        deposit, (v) loan participations, (vi) repurchase agreements, (vii)
        securities owned but subject to a repurchase agreement and (viii) currency,
        interest rate and commodity swaps.

       

      4. For
        purposes of determining the aggregate amount of securities owned and/or invested
        on a discretionary basis by the Transferee, the Transferee used the cost
        of such
        securities to the Transferee and did not include any of the securities referred
        to in the preceding paragraph. Further, in determining such aggregate amount,
        the Transferee may have included securities owned by subsidiaries of the
        Transferee, but only if such subsidiaries are consolidated with the Transferee
        in its financial statements prepared in accordance with generally accepted
        accounting principles and if the investments of such subsidiaries are managed
        under the Transferee’s direction. However, such securities were not included if
        the Transferee is a majority-owned, consolidated subsidiary of another
        enterprise and the Transferee is not itself a reporting company under the
        Securities Exchange Act of 1934.

       

      5. The
        Transferee acknowledges that it is familiar with Rule 144A and understands
        that
        the Transferor and other parties related to the Certificates are relying
        and
        will continue to rely on the statements made herein because one or more sales
        to
        the Transferee may be in reliance on Rule 144A.

       

      ___ ___  Will
        the
        Transferee be purchasing the Certificates

      Yes No                
        only
        for
        the Transferee’s own account?

       

      6. If
        the
        answer to the foregoing question is “no”, the Transferee agrees that, in
        connection with any purchase of securities sold to the Transferee for the
        account of a third party (including any separate account) in reliance on
        Rule
        144A, the Transferee will only purchase for the account of a third party
        that at
        the time is a “qualified institutional buyer” within the meaning of Rule 144A.
        In addition, the Transferee agrees that the Transferee will not purchase
        securities for a third party unless the Transferee has obtained a current
        representation letter from such third party or taken other appropriate steps
        contemplated by Rule 144A to conclude that such third party independently
        meets
        the definition of “qualified institutional buyer” set forth in Rule
        144A.

       

      7. The
        Transferee will notify each of the parties to which this certification is
        made
        of any changes in the information and conclusions herein. Until such notice
        is
        given, the Transferee’s purchase of the Certificates will constitute a
        reaffirmation of this certification as of the date of such purchase. In
        addition, if the Transferee is a bank or savings and loan as provided above,
        the
        Transferee agrees that it will furnish to such parties updated annual financial
        statements promptly after they become available.

       

      
        

          

          
            1 Transferee
              must own and/or invest on a discretionary basis at least $100,000,000
              in
              securities unless Transferee is a dealer, and, in that case, Transferee
              must own
              and/or invest on a discretionary basis at least $10,000,000 in
              securities.

      The

“Transferor”) and Wells Fargo Bank, N.A., as Securities Administrator, with
        respect to the mortgage backed pass-through certificates (the “Certificates”)
        described in the Transferee Certificate to which this certification relates
        and
        to which this certification is an Annex:

       

      1. As
        indicated below, the undersigned is the President, Chief Financial Officer
        or
        Senior Vice President of the entity purchasing the Certificates (the
“Transferee”) or, if the Transferee is a “qualified institutional buyer” as that
        term is defined in Rule 144A under the Securities Act of 1933 (“Rule 144A”)
        because the Transferee is part of a Family of Investment Companies (as defined
        below), is such an officer of the investment adviser (the
“Adviser”).

       

      2. In
        connection with purchases by the Transferee, the Transferee is a “qualified
        institutional buyer” as defined in Rule 144A because (i) the Transferee is an
        investment company registered under the Investment Company Act of 1940, and
        (ii)
        as marked below, the Transferee alone, or the Transferee’s Family of Investment

        securities referred to below) as of the end of the Transferee’s most recent
        fiscal year. For purposes of determining the amount of securities owned by
        the

        securities was used.

                The
                  Transferee owned $________________________ in securities (other
                  than the
                  excluded securities referred to below) as of the end of the Transferee’s
                  most recent fiscal year (such amount being calculated in accordance
                  with
                  Rule 144A).

              

      

       

      
        	 	
                ___

                  in the

                  securities referred to below) as of the end of the Transferee’s most
                  recent fiscal year (such amount being calculated in accordance
                  with Rule
                  144A).

              

      

       

      3. The
        term
“Family
        of Investment Companies”
        as used
        herein means two or more registered investment companies (or series thereof)
        that have the same investment adviser or investment advisers that are affiliated
        (by virtue of being majority owned subsidiaries of the same parent or because
        one investment adviser is a majority owned subsidiary of the
        other).

       

      4. The
        term
“securities”
        as used
        herein does not include (i) securities of issuers that are affiliated with
        the
        Transferee or are part of the Transferee’s Family of Investment Companies, (ii)
        securities issued or guaranteed by the U.S. or any instrumentality thereof,

        which
        this certification is being made are relying and will continue to rely on
        the
        statements made herein because one or more sales to the Transferee will be

        reliance on Rule 144A. In addition, the Transferee will only purchase for
        the
        Transferee’s own account.

       

      6. The
        undersigned will notify the parties to which this certification is made of

        Transferee’s purchase of the Certificates will constitute a reaffirmation of
        this certification by the undersigned as of the date of such
        purchase.

        as follows:

       

      Neither
        the Transferor nor anyone acting on its behalf has (a) offered, pledged,
        sold,
        disposed of or otherwise transferred any Certificate, any interest in any
        Certificate or any other similar security to any person in any manner, (b)
        has
        solicited any offer to buy or to accept a pledge, disposition or other transfer
        of any Certificate, any interest in any Certificate or any other similar
        security from any person in any manner, (c) has otherwise approached or
        negotiated with respect to any Certificate, any interest in any Certificate
        or

        general solicitation by means of general advertising or in any other manner,
        or
        (e) has taken any other action, that (as to any of (a) through (e) above)
        would
        constitute a distribution of the Certificates under the Securities Act of
        1933
        (the “Act’), that would render the disposition of any Certificate a violation of
        Section 5 of the Act or any state securities law, or that would require
        registration or qualification pursuant thereto. The Transferor will not act,
        in
        any manner set forth in the foregoing sentence with respect to any Certificate.
        The Transferor has not and will not sell or otherwise transfer any of the

      Ladies
        and Gentlemen:

       

      In
        connection with the transfer by ______________________ (the “Transferor”) to
        __________________________ (the “Transferee”) of the captioned mortgage
        pass-through certificates (the “Certificates”), the Transferee hereby certifies
        as follows:

       

      1. The
        Transferee understands that (a) the Certificates have not been and will not
        be
        registered or qualified under the Securities Act of 1933, as amended (the
“Act”)
        or any state securities law, (b) the Depositor is not required to so register
        or
        qualify the Certificates, (c) the Certificates may be resold only if registered
        and qualified pursuant to the provisions of the Act or any state securities
        law,
        or if an exemption from such registration and qualification is available,
        (d)
        the Pooling and Servicing Agreement contains restrictions regarding the transfer
        of the Certificates and (e) the Certificates will bear a legend to the foregoing
        effect.

       

      2. The
        Transferee is acquiring the Certificates for its own account for investment
        only
        and not with a view to or for sale in connection with any distribution thereof
        in any manner that would violate the Act or any applicable state securities
        laws.

       

      3. The
        Transferee is (a) a substantial, sophisticated institutional investor having
        such knowledge and experience in financial and business matters, and, in
        particular, in such matters related to securities similar to the Certificates,
        such that it is capable of evaluating the merits and risks of investment
        in the
        Certificates, (b) able to bear the economic risks of such an investment and
        (c)
        an “accredited investor” within the meaning of Rule 501(a) promulgated pursuant
        to the Act.

       

      4. The
        Transferee has been furnished with, and has had an opportunity to review
        (a) a
        copy of the Pooling and Servicing Agreement and (b) such other information
        concerning the Certificates, the Mortgage Loans and the Depositor as has
        been
        requested by the Transferee from the Depositor or the Transferor and is relevant
        to the Transferee’s decision to purchase the Certificates. The Transferee has
        had any questions arising from such review answered by the Depositor or the
        Transferor to the satisfaction of the Transferee.

       

      5. The
        Transferee has not and will not nor has it authorized or will it authorize
        any
        person to (a) offer, pledge, sell, dispose of or otherwise transfer any
        Certificate, any interest in any Certificate or any other similar security
        to
        any person in any manner, (b) solicit any offer to buy or to accept a pledge,
        disposition of other transfer of any Certificate, any interest in any
        Certificate or any other similar security from any person in any manner,
        (c)
        otherwise approach or negotiate with respect to any Certificate, any interest
        in
        any Certificate or any other similar security with any person in any manner,
        (d)
        make any general solicitation by means of general advertising or in any other
        manner or (e) take any other action, that (as to any of (a) through (e) above)
        would constitute a distribution of any Certificate under the Act, that would
        render the disposition of any Certificate a violation of Section 5 of the
        1933
        Act or any state securities law, or that would require registration or
        qualification pursuant thereto. The Transferee will not sell or otherwise
        transfer any of the Certificates, except in compliance with the provisions
        of
        the Pooling and Servicing Agreement.

       

      6. The
        Transferee: (a) is not an employee benefit or other plan subject to the
        prohibited transaction provisions of the Employee Retirement Income Security
        Act
        of 1974, as amended (“ERISA”), or Section 4975 of the Internal Revenue Code of
        1986, as amended (the “Code”) (each, a “Plan”), or any other person (including
        an investment manager, a named fiduciary or a trustee of any Plan) acting,
        directly or indirectly, on behalf of or purchasing any Certificate with “plan
        assets” of any Plan within the meaning of the Department of Labor (“DOL”)
        regulation at 29 C.F.R. §12510.3-101 or (b) [[for Class I-P1, Class I-P2, Class
        II/V-P1, Class II/V-P2] has provided the Securities Administrator with an
        opinion of counsel on which the Trustee, the Depositor, the Master Servicer
        and
        the Securities Administrator may rely, acceptable to and in form and substance
        satisfactory to the Trustee to the effect that the purchase of Certificates
        is
        permissible under applicable law, will not constitute or result in any
        non-exempt prohibited transaction under ERISA or Section 4975 of the Code
        and
        will not subject the Trust Fund, the Trustee, the Depositor, the Master Servicer
        or the Securities Administrator to any obligation or liability (including
        obligations or liabilities under ERISA or Section 4975 of the Code) in addition
        to those undertaken in the Pooling and Servicing Agreement.] [[for Class
        B-3,
        Class B-4, Class B-5] (i) is an insurance company, (ii) the source of funds
        used
        to acquire or hold the certificate or interest therein is an “insurance company
        general account,” as such term is defined in Prohibited Transaction Class
        Exemption (“PTCE”) 95-60, and (iii) (A) prior to the termination of the
        Supplemental Interest Trust, the acquisition and holding of such Certificate
        and
        the separate right to receive payments from the Supplemental Interest Trust
        are
        eligible for the exemptive relief under PTCE 95-60 and (B) subsequent to
        the
        termination of the Supplemental Interest Trust, the conditions in Sections
        I and
        III of PTCE 95-60 have been satisfied.]

       

      In
        addition, the Transferee hereby certifies, represents and warrants to, and
        covenants with, the Depositor, the Trustee, the Securities Administrator
        and the
        Master Servicer that the Transferee will not transfer such Certificates to
        any
        Plan or person unless such Plan or person meets the requirements set forth
        in
        paragraph 6 above.

       

      All
        capitalized terms used but not otherwise defined herein have the respective
        meanings assigned thereto in the Pooling and Servicing Agreement (the “Pooling
        and Servicing Agreement”), dated as of January 1, 2006, among Deutsche Alt-A

      Reference
        is hereby made to the Pooling and Servicing Agreement (the “Agreement”), dated
        as of January 1, 2006, among Deutsche Alt-A Securities, Inc. (the “Depositor”),
        Wells Fargo Bank, N.A., as master and securities administrator (the “Master
        Servicer”) and HSBC Bank USA, National Association, as trustee (the “Trustee”).
        Capitalized terms used herein but not defined herein shall have the meanings
        assigned thereto in the Agreement.

       

      This
        letter relates to U.S. $[__________] Certificate Principal Balance of Class
        [B-[3][4][5]][I-P1][I-P2][II/V-P1][II/V-P2]] Certificates (the “Certificates”)
        which are held in the name of [name of transferor] (the “Transferor”) to effect
        the transfer of the Certificates to a person who wishes to take delivery
        thereof
        in the form of an equivalent beneficial interest [name of transferee] (the
        “Transferee”).

       

      In
        connection with such request, the Transferor hereby certifies that such transfer
        has been effected in accordance with the transfer restrictions set forth
        in the
        Agreement and the private placement memorandum dated January 31, 2006 relating
        to the Certificates and that the following additional requirements (if
        applicable) were satisfied:

       

      (a) the
        offer
        of the Certificates was not made to a person in the United States;

       

      (b) at
        the
        time the buy order was originated, the Transferee was outside the United
        States
        or the Transferor and any person acting on its behalf reasonably believed
        that
        the Transferee was outside the United States;

       

      (c) no
        directed selling efforts were made in contravention of the requirements of
        Rule
        903(b) or 904(b) of Regulation S, as applicable;

       

      (d) the

        requirements of the Securities Act;

      (f) the
        transfer was made in accordance with the applicable provisions of Rule 903(b)(2)
        or (3) or Rule 904(b)(1), as the case may be; and

       

      (g) the
        Transferee understands that the Certificates have not been and will not be
        registered under the Securities Act, that any offers, sales or deliveries
        of the
        Certificates purchased by the Transferee in the United States or to U.S.
        persons
        prior to the date that is 40 days after the later of (i) the commencement
        of the
        offering of the Certificates and (ii) the Closing Date, may constitute a
        violation of United States law, and that (x) distributions of principal and
        interest and (y) the exchange of beneficial interests in a Temporary Regulation
        S Global Certificate for beneficial interests in the related Permanent
        Regulation S Global Certificate, in each case, will be made in respect of

        of
        non-U.S. beneficial ownership, at the times and in the manner set forth in

          been
          satisfied upon delivery to the Purchaser or any assignee, transferee or
          designee
          of the Purchaser promptly upon receipt thereof by or on behalf of the Seller
          of
          either the original or a copy of such document certified by the applicable
          public recording office to be a true and complete copy of the
          original.

         

        In
          the

        Each
          original document relating to a Mortgage Loan which is not delivered to
          the
          Purchaser or its assignee, transferee or designee, if held by the Seller,
          shall
          be so held for the benefit of the Purchaser, its assignee, transferee or
          designee.

         

        (c)  Acceptance
          of Mortgage Loans.
          The
          documents delivered pursuant to Section 4(b) hereof shall be reviewed by
          the
          Purchaser or any assignee, transferee or designee of the Purchaser at any
          time
          before or after the Closing Date (and with respect to each document permitted
          to
          be delivered after the Closing Date, within seven (7) days of its delivery)
          to
          ascertain that all required documents have been executed and received and
          that
          such documents relate to the Mortgage Loans identified on the Closing
          Schedule.

         

        (d)  Transfer
          of Interest in Agreements.
          The
          Purchaser has the right to assign its interest under this Agreement, in
          whole or
          in part, to the Trustee, as may be required to effect the purposes of the
          Pooling and Servicing Agreement, without the consent of the Seller, and
          the
          assignee shall succeed to the rights and obligations hereunder of the Purchaser.
          Any expense reasonably incurred by or on behalf of the Purchaser or the
          Trustee
          in connection with enforcing any obligations of the Seller under this Agreement
          will be promptly reimbursed by the Seller.

         

        (e)  Examination
          of Mortgage Files.
          Prior
          to the Closing Date, the Seller shall either (i) deliver in escrow to the
          Purchaser or to any assignee, transferee or designee of the Purchaser for
          examination the Mortgage File pertaining to each Mortgage Loan or (ii)
          make such
          Mortgage Files available to the Purchaser or to any assignee, transferee
          or
          designee of the Purchaser for examination. Such examination may be made
          by the
          Purchaser or the Trustee, and their respective designees, upon reasonable
          notice
          to the Seller during normal business hours before the Closing Date and
          within
          sixty (60) days after the Closing Date. If any such person makes such
          examination prior to the Closing Date and identifies any Mortgage Loans
          that do
          not conform to the requirements of the Purchaser as described in this Agreement,
          such Mortgage Loans shall be deleted from the Closing Schedule. The Purchaser
          may, at its option and without notice to the Seller, purchase all or part
          of the
          Mortgage Loans without conducting any partial or complete examination.
          The fact
          that the Purchaser or any person has conducted or has failed to conduct
          any
          partial or complete examination of the Mortgage Files shall not affect
          the
          rights of the Purchaser or any assignee, transferee or designee of the
          Purchaser
          to demand repurchase or other relief as provided herein or under the Pooling
          and
          Servicing Agreement.

        The
          Seller hereby represents and warrants to the Purchaser, as of the date
          hereof
          and as of the Closing Date, and covenants, that:

          conducted by it to the extent material to the consummation of the transactions
          contemplated herein. The Agreement has been duly authorized, executed and
          delivered by the Seller. The Seller had the full corporate power and authority

          terms and conditions of, this Agreement;

          a legal, valid and binding obligation of the Seller, enforceable against
          it in
          accordance with its terms except as the enforceability thereof may be limited
          by
          bankruptcy, insolvency or reorganization or by general principles of
          equity;

         

        (iii)  The
          execution, delivery and performance of this Agreement by the Seller (x)
          does not
          conflict and will not conflict with, does not breach and will not result
          in a
          breach of and does not constitute and will not constitute a default (or
          an
          event, which with notice or lapse of time or both, would constitute a default)
          under (A) any terms or provisions of the articles of incorporation or by-laws
          of
          the Seller, (B) any term or provision of any material agreement, contract,
          instrument or indenture, to which the Seller is a party or by which the
          Seller
          or any of its property is bound, or (C) any law, rule, regulation, order,
          judgment, writ, injunction or decree of any court or governmental authority
          having jurisdiction over the Seller or any of its property and (y) does
          not
          create or impose and will not result in the creation or imposition of any
          lien,
          charge or encumbrance which would have a material adverse effect upon the
          Mortgage Loans or any documents or instruments evidencing or securing the
          Mortgage Loans;

         

        (iv)  No
          consent, approval, authorization or order of, registration or filing with,
          or
          notice on behalf of the Seller to any governmental authority or court is
          required, under federal laws or the laws of the State of New York, for
          the
          execution, delivery and performance by the Seller of, or compliance by
          the
          Seller with, this Agreement or the consummation by the Seller of any other
          transaction contemplated hereby and by the Pooling and Servicing Agreement;
          provided, however, that the Seller makes no representation or warranty
          regarding
          federal or state securities laws in connection with the sale or distribution
          of
          the Certificates;

         

        (v)  The
          Seller is not in violation of, and the execution and delivery of this Agreement
          by the Seller and its performance and compliance with the terms of this
          Agreement will not constitute a violation with respect to, any order or
          decree
          of any court or any order or regulation of any federal, state, municipal
          or
          governmental agency having jurisdiction over the Seller or its assets,
          which
          violation might have consequences that would materially and adversely affect
          the
          condition (financial or otherwise) or the operation of the Seller or its
          assets

        (vi)  Immediately
          prior to the sale of the Mortgage Loans to the Purchaser as herein contemplated,
          the Seller was the owner of the related Mortgage and the indebtedness evidenced
          by the related Mortgage Note, and, upon the payment to the Seller of the
          Purchase Price, in the event that the Seller retains or has retained record
          title, the Seller shall retain such record title to each Mortgage, each
          related
          Mortgage Note and the related Mortgage Files with respect thereto in trust
          for
          the Purchaser as the owner thereof from and after the date hereof;

         

        (vii)  There
          are
          no actions or proceedings against, or investigations known to it of, the
          Seller
          before any court, administrative or other tribunal (A) that might prohibit
          its
          entering into this Agreement, (B) seeking to prevent the sale of the Mortgage
          Loans by the Seller or the consummation of the transactions contemplated
          by this
          Agreement or (C) that might prohibit or materially and adversely affect
          the
          performance by the Seller of its obligations under, or validity or
          enforceability of, this Agreement;

         

        (viii)  The
          consummation of the transactions contemplated by this Agreement are in
          the
          ordinary course of business of the Seller, and the transfer, assignment
          and
          conveyance of the Mortgage Notes and the Mortgages by the Seller pursuant
          to
          this Agreement are not subject to the bulk transfer or any similar statutory
          provisions in effect in any relevant jurisdiction, except any as may have
          been
          complied with;

         

        (ix)  There
          is
          no litigation currently pending or, to the best of the Seller’s knowledge
          without independent investigation, threatened against the Seller that would
          reasonably be expected to adversely affect the transfer of the Mortgage
          Loans,
          the issuance of the Certificates or the execution, delivery, performance
          or
          enforceability of this Agreement; and

         

        (x)  The
          information set forth in the applicable part of the Closing Schedule relating
          to
          the existence of a Prepayment Charge is complete, true and correct in all
          material respects at the date or dates respecting which such information
          is
          furnished and each Prepayment Charge is permissible and enforceable in
          accordance with its terms upon the mortgagor’s full and voluntary principal
          prepayment under applicable law, except to the extent that: (1) the
          enforceability thereof may be limited by bankruptcy, insolvency, moratorium,
          receivership and other similar laws relating to creditors’ rights; (2) the
          collectability thereof may be limited due to acceleration in connection
          with a
          foreclosure or other involuntary prepayment; or (3) subsequent changes
          in
          applicable law may limit or prohibit enforceability thereof under applicable
          law. 

         

        SECTION
          6.  Representations
          and Warranties of the Seller Relating to the Mortgage
          Loans.

         

        The
          Seller hereby represents and warrants to the Purchaser that as to each
          Mortgage
          Loan as of the Closing Date (unless otherwise set forth herein):

         

        (i)  The
          information set forth in the Closing Schedule is true and correct in all
          material respects as of the Cut-Off Date;

         

        (ii)  No
          Monthly Payment required to be made under any Mortgage Loan has been
          contractually delinquent by one month or more at any time preceding the
          date
          such Mortgage Loan was purchased by the Seller;

         

        (iii)  To
          the
          best of the Seller’s knowledge, there
          are
          no delinquent taxes, assessment liens or insurance premiums affecting the
          related Mortgaged Property;

         

        (iv)  The
          buildings and improvements on the Mortgaged Property are insured against
          loss by
          fire and hazards of extended coverage (excluding earthquake insurance)
          in an
          amount which is at least equal to the lesser of (i) the amount necessary
          to
          compensate for any damage or loss to the improvements which are a part
          of such
          property on a replacement cost basis or (ii) the outstanding principal
          balance
          of the Mortgage Loan. To the best of the Seller’s knowledge, if the Mortgaged
          Property is in an area identified on a flood hazard map or flood insurance
          rate
          map issued by the Federal Emergency Management Agency as having special
          flood
          hazards (and such flood insurance has been made available), a flood insurance
          policy meeting the requirements of the current guidelines of the Federal
          Insurance Administration is in effect. All such insurance policies contain
          a
          standard mortgagee clause naming the originator of the Mortgage Loan, its
          successors and assigns as mortgagee and the Seller has not engaged in any
          act or
          omission which would impair the coverage of any such insurance policies.
          Except
          as may be limited by applicable law, the Mortgage obligates the Mortgagor
          thereunder to maintain all such insurance at the Mortgagor's cost and expense,
          and on the Mortgagor's failure to do so, authorizes the holder of the Mortgage
          to maintain such insurance at Mortgagor's cost and expense and to seek
          reimbursement therefor from the Mortgagor;

         

        (v)  Each
          Mortgage Loan and the related Prepayment Charge complied in all material
          respects with any and all requirements of any federal, state or local law
          including, without limitation, usury, truth in lending, real estate settlement
          procedures, consumer credit protection, equal credit opportunity, predatory
          and
          abusive lending, fair housing, or disclosure laws applicable to the origination
          and servicing of Mortgage Loans of a type similar to the Mortgage Loans
          and the
          consummation of the transactions contemplated hereby will not involve the
          violation of any such laws;

         

        (vi)  Except
          as
          the Mortgage File may reflect, the Mortgage has not been satisfied, cancelled,
          subordinated or rescinded in whole or in part, and the Mortgaged Property
          has
          not been released from the lien of the Mortgage, in whole or in part, nor
          has
          any instrument been executed that would effect any such satisfaction,
          cancellation, subordination, rescission or release;

         

        (vii)  The
          Mortgage was recorded or was submitted for recording in accordance with
          all
          applicable laws and is a valid, existing and enforceable first lien on
          the
          Mortgaged Property including all improvements on the Mortgaged
          Property;

         

        (viii)  The
          Mortgage Note and the related Mortgage are genuine and each is the legal,
          valid
          and binding obligation of the maker thereof, insured under the related
          title
          policy, and enforceable in accordance with its terms, except to the extent
          that
          the enforceability thereof may be limited by a bankruptcy, insolvency or
          reorganization;

         

        (ix)  The
          Seller is the sole legal, beneficial and equitable owner of the Mortgage
          Note
          and the Mortgage and has the full right to convey, transfer and sell the
          Mortgage Loan to the Purchaser free and clear of any encumbrance, equity,
          lien,
          pledge, charge, claim or security interest and immediately upon the sale,
          assignment and endorsement of the Mortgage Loans from the Seller to the
          Purchaser, the Purchaser shall have good and indefeasible title to and
          be the
          sole legal owner of the Mortgage Loans subject only to any encumbrance,
          equity,
          lien, pledge, charge, claim or security interest arising out of the Purchaser’s
          actions;

         

        (x)  Each
          Mortgage Loan is covered by either (a) an attorney’s opinion of title and
          abstract of title the form and substance of which is acceptable to mortgage
          lending institutions making mortgage loans in the area where the Mortgaged
          Property is located or (b) a valid and binding American Land Title Association
          lender's title insurance policy issued by a title insurer qualified to
          do
          business in the jurisdiction where the Mortgaged Property is located. No
          claims
          have been filed under such lender's title insurance policy, and the Seller
          has
          not done, by act or omission, anything that would impair the coverage of
          the
          lender's title insurance policy;

         

        (xi)  To
          the
          best of the Seller’s knowledge, there is no material default, breach, violation
          event or event of acceleration existing under the Mortgage or the Mortgage
          Note
          and no event which, with the passage of time or with notice and the expiration
          of any grace or cure period, would constitute a material default, breach,
          violation or event of acceleration, and the Seller has not, nor has its
          predecessors, waived any material default, breach, violation or event of
          acceleration;

         

        (xii)  To
          the
          best of the Seller’s knowledge, no Mortgage Loan permits negative amortization
          or the deferral of accrual interest;

         

        (xiii)  As
          of the
          date the Mortgage Loan was purchased by the Seller, to the best of the
          Seller’s
          knowledge, there was no proceeding pending for the total or partial condemnation
          of the Mortgaged Property;

         

        (xiv)  To
          the
          best of the Seller’s knowledge, the Mortgage Loan is not subject to any valid
          right of rescission, set-off, counterclaim or defense, including without
          limitation the defense of usury, nor will the operation of any of the terms
          of
          the Mortgage Note or the Mortgage, or the exercise of any right thereunder,
          render either the Mortgage Note or the Mortgage unenforceable, in whole
          or in
          part, or subject to any such right of rescission, set-off, counterclaim
          or
          defense, including without limitation the defense of usury, and no such
          right of
          rescission, set-off, counterclaim or defense has been asserted with respect
          thereto;

         

        (xv)  To
          the
          best of the Seller’s knowledge, each Mortgage Loan was originated on forms
          acceptable to FNMA or FHLMC;

         

        (xvi)  The
          Mortgaged Property is free of material damage and in good repair, excepting
          therefrom any Mortgage Loan subject to an escrow withhold as shown on the
          Closing Schedule and only to the extent of that escrow withhold;

         

        (xvii)  All
          parties to the Mortgage Note had the legal capacity to execute the Mortgage
          Note
          and the Mortgage, and the Mortgage Note and the Mortgage have been duly
          executed
          by such parties;

         

        (xviii)  To
          the
          best of the Seller’s knowledge, at the time of origination of the Mortgage Loan,
          no appraised improvement located on or being part of the Mortgaged Property
          was
          in violation of any applicable zoning law or regulation and to the best
          of the
          Seller’s knowledge, all inspections, licenses and certificates required in
          connection with the origination of any Mortgage Loan with respect to the
          occupancy of the Mortgaged Property, have been made or obtained from the
          appropriate authorities;

         

        (xix)  The
          Mortgage File contains an appraisal of the related Mortgaged Property which
          satisfied the standards of FNMA and FHLMC and was made prior to the origination
          of the Mortgage Loan by a qualified appraiser, duly appointed by the related
          originator and was made in accordance with the relevant provisions of the
          Financial Institutions Reform, Recovery, and Enforcement Act of
          1989;

         

        (xx)  Each
          Mortgage Loan is an obligation which is principally secured by an interest
          in
          real property within the meaning of Treasury Regulation section 1.860G
          2(a);

         

        (xxi)  Each
          Mortgage Loan is directly secured by a first lien on, and consists of a
          single
          parcel of, real property with a detached one-to-four family residence erected
          thereon, a townhouse or an individual condominium unit in a condominium
          project,
          or an individual unit in a planned unit development or stock in a cooperative
          housing corporation;

         

        (xxii)  With
          respect to any Mortgage Loan with an original Loan-to-Value Ratio greater
          than
          80%, the Mortgage Loan will be insured by a primary mortgage guaranty insurance
          policy, issued by an insurer which meets the requirements of FNMA and FHLMC,
          which insures that portion of the Mortgage Loan in excess of the portion
          of the
          appraised value of the Mortgaged Property required by FNMA. All provisions
          of
          such primary mortgage guaranty insurance policy have been and are being
          complied
          with, such policy is in full force and effect, and all premiums due thereunder
          have been paid. Any Mortgage subject to any such primary mortgage guaranty
          insurance policy obligates the Mortgagor thereunder to maintain such insurance
          and to pay all premiums and charges in connection therewith. The Mortgage
          Interest Rate for the Mortgage Loan does not include any such insurance
          premium;

         

        (xxiii)  Each
          Mortgage Loan was originated by a savings and loan association, savings
          bank,
          commercial bank, credit union, insurance company, or similar institution
          which
          is supervised and examined by a federal or state authority, or by a mortgagee
          approved by the Secretary of Housing and Urban Development or any successor
          thereto;

         

        (xxiv)  No
          Mortgage Loan is (a) subject to, covered by or in violation of the provisions
          of
          the Homeownership and Equity Protection Act of 1994, as amended, (b) a
“high
          cost”, “covered”, “abusive”, “predatory”, or “high risk” mortgage loan (or a
          similarly designated loan using different terminology) under any federal,
          state
          or local law, including without limitation, the provisions of the Georgia
          Fair
          Lending Act, New York Banking Law, Section 6-1, the Arkansas Home Loan
          Protection Act, effective as of June 14, 2003, Kentucky State Statute KRS
          360.100, effective as of June 25, 2003 or any other statute or regulation
          providing assignee liability to holders of such mortgage loans, (c) subject
          to
          or in violation of any such or comparable federal, state or local statutes
          or
          regulations;

         

        (xxv)  [Reserved];

         

        (xxvi)  No
          Mortgage Loan is a “High-Cost Home Loan” or a refinanced “Covered Home Loan,” in
          each case, as defined in the New Jersey Home Ownership Act effective November
          27, 2003 (N.J.S.A. 46;10B-22 et seq.);

         

        (xxvii)  No
          Mortgage Loan is a subsection 10 mortgage under the Oklahoma Home Ownership
          and
          Equity protection Act;

         

        (xxviii)  No
          Mortgage Loan is a “High-Cost Home Loan” as defined in the New Mexico Home Loan
          Protection Act effective January 1, 2004 (N.M. Stat. Ann. §§ 58-21A-1 et
          seq.);

         

        (xxix)  No
          Mortgage Loan is a “High-Risk Home Loan” as defined in the Illinois High-Risk
          Home Loan Act effective January 1, 2004 (815 Ill. Comp. Stat. 137/1 et
          seq.);

         

        (xxx)  There
          is

          7.  Repurchase
          Obligation for Defective Documentation and for
          Breach of Representation and Warranty.

         

        (a)  The
          representations and warranties contained in Section 6 shall not be impaired
          by
          any review and examination of the Mortgage Files or other documents evidencing
          or relating to the Mortgage Loans or any failure on the part of the Seller
          or
          the Purchaser to review or examine such documents and shall inure to the
          benefit
          of any assignee, transferee or designee of the Purchaser, including the
          Trustee
          for the benefit of the Certificateholders. With respect to the representations
          and warranties contained herein as to which the Seller has no knowledge,
          if it
          is discovered that the substance of any such representation and warranty
          was
          inaccurate as of the date such representation and warranty was made or
          deemed to
          be made, and such inaccuracy materially and adversely affects the value
          of the
          related Mortgage Loan or the interest therein of the Purchaser or the
          Purchaser’s assignee, transferee or designee, then notwithstanding the lack of
          knowledge by the Seller with respect to the substance of such representation
          and
          warranty being inaccurate at the time the representation and warranty was
          made,
          the Seller shall take such action described in the following paragraph
          in
          respect of such Mortgage Loan.

         

        Upon
          discovery by the Seller, the Purchaser or any assignee, transferee or designee
          of the Purchaser of any materially defective document in, or that any material
          document was not transferred by the Seller (as listed on the related Custodian’s
          preliminary exception reports, as described in the related Custodial
          Agreement,
          as part
          of any Mortgage File or of a breach of any of the representations and warranties
          contained in Section 6 that materially and adversely affects the value
          of any
          Mortgage Loan or the interest therein of the Purchaser or the Purchaser’s
          assignee, transferee or designee, the party discovering such breach shall
          give
          prompt written notice to the Seller. Within sixty (60) days of its discovery
          or
          its receipt of notice of any such missing documentation that was not transferred
          by the Seller as described above, or of materially defective documentation,
          or
          within sixty (60) days of any such breach of a representation and warranty,
          the
          Seller promptly shall deliver such missing document or cure such defect
          or
          breach in all material respects or, in the event the Seller cannot deliver
          such
          missing document or cannot cure such defect or breach, the Seller shall,
          within
          ninety (90) days of its discovery or receipt of notice of any such missing
          or
          materially defective documentation or within ninety (90) days of any such
          breach
          of a representation and warranty, either (i) repurchase the affected Mortgage
          Loan at the Purchase Price (as such term is defined in the Pooling and
          Servicing
          Agreement) or (ii) pursuant to the provisions of the Pooling and Servicing
          Agreement, cause the removal of such Mortgage Loan from the Trust Fund
          and
          substitute one or more Substitute Loans. The Seller shall amend the Closing
          Schedule to reflect the withdrawal of such Mortgage Loan from the terms
          of this
          Agreement and the Pooling and Servicing Agreement. Notwithstanding the
          foregoing, if the representation made by the Seller in Section 6(xxiv)
          of this
          Agreement is breached, the Trustee shall, in accordance with the terms
          of the
          Pooling and Servicing Agreement, enforce the obligation of the Seller to
          repurchase such Mortgage Loan at the Purchase Price, or to provide a Substitute
          Loan (plus any costs and damages incurred by the Trust Fund in connection
          with
          any violation by any such Mortgage Loan of any predatory or abusive lending
          law)
          within ninety (90) days after the date on which the Seller was notified
          of such
          breach. The Seller shall deliver to the Purchaser such amended Closing
          Schedule
          and shall deliver such other documents as are required by this Agreement
          or the
          Pooling and Servicing Agreement within five (5) days of any such amendment.
          Any
          repurchase pursuant to this Section 7(a) shall be accomplished by transfer
          to an
          account designated by the Purchaser of the amount of the Purchase Price
          in
          accordance with Section 2.3 of the Pooling and Servicing Agreement. Any
          repurchase required by this Section shall be made in a manner consistent
          with
          Section 2.3 of the Pooling and Servicing Agreement.

         

        (b)  If
          the
          representation made by the Seller in Section 5(x) is breached, the Seller
          shall
          not have the right or obligation to cure, substitute or repurchase the
          affected
          Mortgage Loan but shall remit to the Master Servicer for deposit in the
          Distribution Account, prior to the next succeeding Distribution Date, the
          amount
          of the Prepayment Charge indicated on the applicable part of the Closing
          Schedule to be due from the Mortgagor in the circumstances less any amount
          collected and remitted to the Master Servicer for deposit into the Distribution
          Account.

         

        (c)  It
          is
          understood and agreed that the obligations of the Seller set forth in this
          Section 7 to cure or repurchase a defective Mortgage Loan (and to make
          payments
          pursuant to Section 7(b)) constitute the sole remedies of the Purchaser
          against the Seller respecting a missing document or a breach of the
          representations and warranties contained in Section 6.

                    notice or
                    the passage of time, would constitute a default under this

        SECTION
          11.  Servicing.
          The
          Mortgage Loans will be master serviced by the Master Servicer under the
          Pooling
          and Servicing Agreement and serviced by GMAC
          Mortgage Corporation (“GMAC”), GreenPoint Mortgage Funding, Inc. (“GreenPoint”),
          National City Mortgage Co. (“NatCity”), Residential Funding Corporation (“RFC”),
          Franklin Bank, SSB (“Franklin Bank”), IndyMac, F.S.B. (“IndyMac”), Wells Fargo
          Bank, N.A. (“Wells Fargo”) and Countrywide Home Loans Servicing LP
          (“Countrywide”),
          as
          applicable, on behalf of the Trust, pursuant to separate servicing agreements
          identified in the Pooling and Servicing Agreement and assigned to the Purchaser
          on the Closing Date and the Seller has represented to the Purchaser that
          such
          Mortgage Loans are not subject to any other servicing agreements with third
          parties (other than the servicing agreements with GMAC, GreenPoint, Countrywide,
          NatCity, Franklin Bank, IndyMac, Wells Fargo Bank. and RFC). It is understood
          and agreed between the Seller and the Purchaser that the Mortgage Loans
          are to
          be delivered free and clear of any servicing agreements (other than the

          is
          entitled to receive any fee for releasing the Mortgage Loans from any such
          servicing agreement. For so long as the Master Servicer master services
          the
          Mortgage Loans and the applicable Servicer services the Mortgage Loans,
          the
          Master Servicer shall be entitled to the Master Servicing Fee and the applicable
          Servicer shall be entitled to the related Servicing Fee and such other
          payments
          as provided for under the terms of the Pooling and Servicing Agreement
          or the
          related servicing agreement, as applicable.

         

        SECTION
          12.  Mandatory
          Delivery; Grant of Security Interest.
          The
          sale and delivery on the Closing Date of the Mortgage Loans described on
          the
          Closing Schedule in accordance with the terms and conditions of this Agreement
          is mandatory. It is specifically understood and agreed that each Mortgage
          Loan
          is unique and identifiable on the date hereof and that an award of money
          damages
          would be insufficient to compensate the Purchaser for the losses and damages
          incurred by the Purchaser in the event of the Seller’s failure to deliver the
          Mortgage Loans on or before the Closing Date. The Seller hereby grants
          to the
          Purchaser a lien on and a continuing security interest in the Seller’s interest
          in each Mortgage Loan and each document and instrument evidencing each
          such
          Mortgage Loan to secure the performance by the Seller of its obligation
          hereunder, and the Seller agrees that it holds such Mortgage Loans in custody
          for the Purchaser, subject to the Purchaser’s (i) right, prior to the Closing
          Date, to reject any Mortgage Loan to the extent permitted by this Agreement
          and
          (ii) obligation to deliver or cause to be delivered the consideration for
          the
          Mortgage Loans pursuant to Section 8 hereof. Any Mortgage Loans rejected
          by the
          Purchaser shall concurrently therewith be released from the security interest
          created hereby. All rights and remedies of the Purchaser under this Agreement
          are distinct from, and cumulative with, any other rights or remedies under
          this
          Agreement or afforded by law or equity and all such rights and remedies
          may be
          exercised concurrently, independently or successively.

         

        Notwithstanding
          the foregoing, if on the Closing Date, each of the conditions set forth
          in
          Section 8 hereof shall have been satisfied and the Purchaser shall not
          have paid
          or caused to be paid the Purchase Price, or any such condition shall not
          have
          been satisfied and satisfaction of such condition shall not have been waived
          and
          the Purchaser determines not to pay or cause to be paid the Purchase Price,
          the
          Purchaser shall immediately effect the redelivery of the Mortgage Loans,
          if
          delivery to the Purchaser has occurred, and the security interest created
          by
          this Section 12 shall be deemed to have been released.

         

        SECTION
          13.  Notices.
          All
          demands, notices and communications hereunder shall be in writing and shall
          be
          deemed to have been duly given if personally delivered to or mailed by
          registered mail, postage prepaid, or transmitted by fax and, receipt of
          which is
          confirmed by telephone, if to the Purchaser, addressed to the Purchaser

        SECTION
          14.  Severability
          of Provisions.
          Any
          part, provision, representation or warranty of this Agreement that is prohibited
          or that is held to be void or unenforceable shall be ineffective to the
          extent
          of such prohibition or unenforceability without invalidating the remaining
          provisions hereof. Any part, provision, representation or warranty of this
          Agreement that is prohibited or unenforceable or is held to be void or
          unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
          to the extent of such prohibition or unenforceability without invalidating
          the
          remaining provisions hereof, and any such prohibition or unenforceability
          in any
          jurisdiction as to any Mortgage Loan shall not invalidate or render
          unenforceable such provision in any other jurisdiction. To the extent permitted
          by applicable law, the parties hereto waive any provision of law which
          prohibits
          or renders void or unenforceable any provision hereof.

         

        SECTION
          15.  Agreement
          of Parties.
          The
          Seller and the Purchaser each agree to execute and deliver such instruments
          and
          take such actions as either of the others may, from time to time, reasonably
          request in order to effectuate the purpose and to carry out the terms of
          this
          Agreement and the Pooling and Servicing Agreement.

         

        SECTION
          16.  Survival.
          The
          Seller agrees that the representations, warranties and agreements made
          by it
          herein and in any certificate or other instrument delivered pursuant hereto
          shall be deemed to be relied upon by the Purchaser, notwithstanding any
          investigation heretofore or hereafter made by the Purchaser or on its behalf,
          and that the representations, warranties and agreements made by the Seller
          herein or in any such certificate or other instrument shall survive the
          delivery
          of and payment for the Mortgage Loans and shall continue in full force
          and
          effect, notwithstanding any restrictive or qualified endorsement on the
          Mortgage
          Notes and notwithstanding subsequent termination of this Agreement, the
          Pooling
          and Servicing Agreement or the Trust Fund.

         

        SECTION
          17.  GOVERNING
          LAW.
          THIS
          AGREEMENT AND THE RIGHTS, DUTIES, OBLIGATIONS AND RESPONSIBILITIES OF THE
          PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
          LAWS
          (EXCLUDING THE CHOICE OF LAW PROVISIONS) AND DECISIONS OF THE STATE OF
          NEW YORK.
          THE PARTIES HERETO INTEND THAT THE PROVISIONS OF SECTION 5-1401 OF THE
          NEW YORK
          GENERAL OBLIGATIONS LAW SHALL APPLY TO THIS AGREEMENT.

         

        SECTION
          18.  Miscellaneous.
          This
          Agreement may be executed in two or more counterparts, each of which when
          so
          executed and delivered shall be an original, but all of which together
          shall
          constitute one and the same instrument. This Agreement shall inure to the
          benefit of and be binding upon the parties hereto and their respective
          successors and assigns. This Agreement supersedes all prior agreements
          and
          understandings relating to the subject matter hereof. Neither this Agreement
          nor
          any term hereof may be changed, waived, discharged or terminated orally,
          but
          only by an instrument in writing signed by the party against whom enforcement
          of
          the change, waiver, discharge or termination is sought. The headings in
          this
          Agreement are for purposes of reference only and shall not limit or otherwise
          affect the meaning hereof.

         

        It
          is the
          express intent of the parties hereto that the conveyance of the Mortgage
          Loans
          by the Seller to the Purchaser as provided in Section 4 hereof be, and
          be
          construed as, a sale of the Mortgage Loans by the Seller to the Purchaser
          and
          not as a pledge of the Mortgage Loans by the Seller to the Purchaser to
          secure a
          debt or other obligation of the Seller. However, in the event that,
          notwithstanding the aforementioned intent of the parties, the Mortgage
          Loans are
          held to be property of the Seller, then (a) it is the express intent of
          the
          parties that such conveyance be deemed a pledge of the Mortgage Loans by
          the
          Seller to the Purchaser to secure a debt or other obligation of the Seller
          and
          (b) (1) this Agreement shall also be deemed to be a security agreement
          within
          the meaning of Articles 8 and 9 of the New York Uniform Commercial Code,
          (2) the
          conveyance provided for in Section 4 hereof shall be deemed to be a grant
          by the
          Seller to the Purchaser of a security interest in all of the Seller’s right,
          title and interest in and to the Mortgage Loans and all amounts payable
          to the
          holders of the Mortgage Loans in accordance with the terms thereof and
          all
          proceeds of the conversion, voluntary or involuntary, of the foregoing
          into
          cash, instruments, securities or other property, including without limitation
          all amounts, other than investment earnings, from time to time held or
          invested
          in the Protected Accounts established by the Servicers of the related Mortgage
          Loans for the benefit of the owner thereof, whether in the form of cash,
          instruments, securities or other property, (3) the possession by the Purchaser
          or its agent of Mortgage Notes, the related Mortgages and such other items
          of
          property that constitute instruments, money, negotiable documents or chattel
          paper shall be deemed to be “possession by the secured party” for purposes of
          perfecting the security interest pursuant to Section 9-305 of the New York
          Uniform Commercial Code, and (4) notifications to persons holding such
          property
          and acknowledgments, receipts or confirmations from persons holding such
          property shall be deemed notifications to, or acknowledgments, receipts
          or
          confirmations from, financial intermediaries, bailees or agents (as applicable)
          of the Purchaser for the purpose of perfecting such security interest under
          applicable law. Any assignment of the interest of the Purchaser pursuant
          to
          Section 4(d) hereof shall also be deemed to be an assignment of any security
          interest created hereby. The Seller and the Purchaser shall, to the extent
          consistent with this Agreement, take such actions as may be necessary to
          ensure
          that, if this Agreement were deemed to create a security interest in the
          Mortgage Loans, 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 and the Pooling and Servicing
          Agreement.

         

        SECTION
          19.  Third
          Party Beneficiary.
          The
          parties hereto acknowledge and agree that DBSI and each of its respective
          successors and assigns shall have all the rights of a third-party beneficiary
          in
          respect of Section 12 of this Agreement and shall be entitled to rely upon
          and
          directly enforce the provisions of Section 12 of this Agreement.

          Ladies
            and Gentlemen:

          

          The
            purpose of this letter agreement ("Agreement") is to confirm the terms
            and
            conditions of the Transaction entered into on the Trade Date specified
            below
            (the "Transaction") between Deutsche Bank AG ("DBAG") and HSBC Bank USA,
            National Association, not individually, but solely as trustee of the
            Supplemental Interest Trust (“Counterparty”) created under the Pooling and
            Servicing Agreement, dated and effective as of January 1,
            2006,
            among Deutsche Alt-A Securities, Inc., as Depositor, Wells Fargo Bank,
            National
            Association, as Master Servicer and Securities Administrator, and HSBC
            Bank USA,
            National Association, as Trustee (the “Pooling and Servicing Agreement”). This
            Agreement, which evidences a complete and binding agreement between you
            and us
            to enter into the Transaction on the terms set forth below, constitutes
            a
            "Confirmation" as referred to in the "ISDA Form Master Agreement" (as
            defined
            below), as well as a “Schedule” as referred to in the ISDA Form Master
            Agreement.

          

          1. This
            Agreement is subject to the 2000
            ISDA Definitions (the
            “Definitions”), as published by the International Swaps and Derivatives
            Association, Inc. (“ISDA”). You and we have agreed to enter into this Agreement
            in lieu of negotiating a Schedule to the 1992 ISDA Master Agreement
            (Multicurrency—Cross Border) form (the "ISDA Form Master Agreement") but,
            rather, an ISDA Form Master Agreement shall be deemed to have been executed
            by
            you and us on the date we entered into the Transaction. In the event
            of any
            inconsistency between the provisions of this Agreement and the Definitions
            or
            the ISDA Form Master Agreement, this Agreement shall prevail for purposes
            of the
            Transaction. Terms capitalized but not defined herein shall have the
            meanings
            attributed to them in the Pooling and Servicing Agreement.

          

          

          2. The
            terms
            of the particular Transaction to which this Confirmation relates are
            as
            follows:

          (h) Governing
            Law. The
            parties to this Agreement hereby agree that the law of the State of New
            York
            shall govern their rights and duties in whole without regard to conflict
            of law
            provisions thereof other than New York General Obligations Law Sections
            5-1401
            and 5-1402. 

          

          (i) Severability. If
            any
            term, provision, covenant, or condition of this Agreement, or the application
            thereof to any party or circumstance, shall be held to be invalid or
            unenforceable (in whole or in part) for any reason, the remaining terms,
            provisions, covenants, and conditions hereof shall continue in full force
            and
            effect as if this Agreement had been executed with the invalid or unenforceable
            portion eliminated, so long as this Agreement as so modified continues
            to
            express, without material change, the original intentions of the parties
            as to
            the subject matter of this Agreement and the deletion of such portion
            of this
            Agreement will not substantially impair the respective benefits or expectations
            of the parties. 

          

          The
            parties shall endeavor to engage in good faith negotiations to replace
            any
            invalid or unenforceable term, provision, covenant or condition with
            a valid or
            enforceable term, provision, covenant or condition, the economic effect
            of which
            comes as close as possible to that of the invalid or unenforceable term,
            provision, covenant or condition. 

          

          (j) Consent
            to Recording. 
            Each
            party hereto consents to the monitoring or recording, at any time and
            from time
            to time, by the other party of any and all communications between officers

            employees of the parties, waives any further notice of such monitoring
            or
            recording, and agrees to notify its officers and employees of such monitoring
            or
            recording. 

          

          (k) Waiver
            of
            Jury Trial. Each
            party waives any right it may have to a trial by jury in respect of any
            Proceedings relating to this Agreement or any Credit Support Document.

            of
            managing its borrowings or investments, hedging its underlying assets
            or
            liabilities or in connection with a line of business.

          9)

            or future

            performance of any obligation between it and the other party hereunder
            against
            any obligation between it and the other party under any other agreements.
            The
            provisions for Set-off set forth in Section 6(e) of the Agreement shall
            not
            apply for purposes of this Transaction.

          

          10)
            Transfer,
            Amendment and Assignment.
            No
            transfer, amendment, waiver, supplement, assignment or other modification
            of

            respect
            Counterparty as the sole Affected Party (unless otherwise provided
            below): 

           

          (i)         DBAG
            fails to comply with the Rating Agency Downgrade provisions as set forth
            in

            Affected Party with respect to the occurrence of a Termination Event
            described
            in this Section 11(i).

           

          (ii)       
            With
            respect to Counterparty only, any amendment to the Pooling and Servicing
            Agreement which materially adversely affects any of DBAG's rights thereunder
            is
            made without prior written consent of DBAG, where such consent is required
            under
            the Pooling and Servicing Agreement.

           

          (iii)      
            If
            the
            Trustee is unable to pay its Class A Certificates or fails or admits
            in writing
            its inability to pay its Class A Certificates as they become due.

          

          (iv)       If,
            at
            any time, the Master Servicer purchases the Mortgage Loans pursuant to
            Section
            9.1 of the Pooling and Servicing Agreement, then an Additional Termination
            Event
            shall have occurred and Counterparty shall be the sole Affected Party
            with
            respect thereto; provided, however, that notwithstanding Section 6(b)(iv)
            of the
            ISDA Form Master Agreement, only Counterparty shall have the right to
            designate
            an Early Termination Date in respect of this Additional Termination
            Event.

          

          (v)      
            If,
            upon
            the occurrence of a Swap Disclosure Event (as defined in Part 13 below)
            DBAG has
            not, within 15 days after such Swap Disclosure Event complied with any
            of the
            provisions set forth in Part 13(iii) below, then an Additional Termination
            Event
            shall have occurred with respect to DBAG and DBAG shall be the sole Affected
            Party with respect to such Additional Termination Event.

          

          12)
            Rating
            Agency Downgrade.
            In the
            event that DBAG’s short-term unsecured and unsubordinated debt rating is
            withdrawn or reduced below “A-1” by S&P or, if DBAG has both a long-term
            credit rating and a short-term credit rating from Moody’s, and either its
            long-term unsecured and unsubordinated debt rating is withdrawn or reduced
            below
“A2” by Moody’s or its short-term credit rating is withdrawn or reduced below
“P-1” by Moody’s (and together with S&P, the “Swap Rating Agencies”, and
            such rating thresholds, “Approved Rating Thresholds”), then within 30 days after
            such rating withdrawal or downgrade, DBAG shall, subject to the Rating
            Agency
            Condition and at its own expense, either (i) cause another entity to
            replace
            DBAG as party to this Agreement that meets or exceeds the Approved Rating
            Thresholds on terms substantially similar to this Agreement, (ii) obtain
            a
            guaranty of, or a contingent agreement of another person with the Approved
            Rating Thresholds, to honor, DBAG’s obligations under this Agreement, (iii) post
            collateral which will be sufficient to restore the immediately prior
            ratings of
            the Certificates, or (iv) establish any other arrangement satisfactory
            to the
            Swap Rating Agencies, which will be sufficient to restore the immediately
            prior
            ratings of the Certificates. In the event that DBAG’s long-term unsecured and
            unsubordinated debt rating is reduced below “BBB-” or its short-term unsecured
            and unsubordinated debt rating is reduced below “A-3” or is withdrawn by
            S&P, then within 10 days after such rating withdrawal or downgrade, DBAG
            shall, subject to the Rating Agency Condition and at its own expense,
            either (i)
            cause another entity to replace DBAG as party to this Agreement that
            meets or
            exceeds the Approved Rating Thresholds on terms substantially similar
            to this
            Agreement or (ii) obtain a guaranty of, or a contingent agreement of
            another
            person with the Approved Rating Thresholds, to honor, DBAG’s obligations under
            this Agreement. For purposes of this provision, “Rating Agency Condition” means,
            with respect to any particular proposed act or omission to act hereunder
            that
            the party acting or failing to act must consult with each of the Swap
            Rating
            Agencies then providing a rating of the Certificates and receive from
            each of
            the Swap Rating Agencies a prior written confirmation that the proposed
            action
            or inaction would not cause a downgrade or withdrawal of the then-current
            rating
            of the Certificates.

          

          13)
            Compliance
            with Regulation AB.
            

          

          (i)       
            DBAG
            agrees and acknowledges that the Depositor is required under Regulation
            AB under
            the Securities Act of 1933, as amended, and the Securities Exchange Act
            of 1934,
            as amended (the “Exchange Act”) (“Regulation AB”), to disclose certain financial
            information regarding DBAG or its group of affiliated entities, if applicable,
            depending on the aggregate “significant percentage” of this Agreement and any
            other derivative contracts between DBAG or its group of affiliated entities,
            if
            applicable, and Counterparty, as calculated from time to time in accordance
            with
            Item 1115 of Regulation AB.

          

          (ii)       
            It
            shall
            be a swap disclosure event (“Swap Disclosure Event”) if, on any Business Day
            after the date hereof, the Depositor requests from DBAG the applicable
            financial
            information described in Item 1115 of Regulation AB (such request to
            be based on
            a reasonable determination by the Depositor, in good faith, that such
            information is required under Regulation AB) (the “Swap Financial
            Disclosure”).

          

          (iii)      
            Upon
            the
            occurrence of a Swap Disclosure Event, DBAG, at its own expense, shall
            (a)
            provide to the Depositor the Swap Financial Disclosure, (b) secure another
            entity to replace DBAG as party to this Agreement on terms substantially
            similar
            to this Agreement which entity (or a guarantor therefore) meets or exceeds
            the
            Approved Rating Thresholds and which satisfies the Rating Agency Condition
            and
            which entity is able to comply with the requirements of Item 1115 of
            Regulation
            AB or (c) obtain a guaranty of the DBAG’s obligations under this Agreement from
            an affiliate of the DBAG, subject to the Rating Agency Condition, that
            is able
            to comply with the financial information disclosure requirements of Item
            1115 of
            Regulation AB, such that disclosure provided in respect of the affiliate
            will
            satisfy any disclosure requirements applicable to the Swap Provider,
            and cause
            such affiliate to provide Swap Financial Disclosure. If permitted by
            Regulation
            AB, any required Swap Financial Disclosure may be provided by incorporation
            by
            reference from reports filed pursuant to the Exchange Act. 

          

          (iv)     
            DBAG
            and
            the primary obligor under any Credit Support Document agree that, in
            the event
            that DBAG provides Swap Financial Disclosure to the Depositor in accordance
            with
            Part 13(iii)(a) or causes its affiliate to provide Swap Financial Disclosure
            to
            the Depositor in accordance with Part 13(iii)(c), DBAG and such primary
            obligor
            will indemnify and hold harmless the Depositor, its respective directors
            or
            officers and any person controlling the Depositor, from and against any
            and all
            losses, claims, damages and liabilities caused by any untrue statement
            or
            alleged untrue statement of a material fact contained in such Swap Financial
            Disclosure or caused by any omission or alleged omission to state in
            such Swap
            Financial Disclosure a material fact, when considered in conjunction
            with any
            other information regarding Party A or the derivative instrument being
            written
            by Party A in the final prospectus for the Depositor-2006-SL1, required
            to be
            stated therein or necessary to make the statements therein, in light
            of the
            circumstances under which they were made, not misleading.

    WHEREAS,

      and the Trustee desire to amend the terms of the Agreement pursuant to and
      in
      accordance with the first paragraph of Section 12.01 of the
      Agreement.

     

    NOW,
      THEREFORE, in consideration of the mutual premises and agreements herein, the
      the Depositor, the Servicers, the Master Servicer, the Securities Administrator
      and the Trustee agree as follows:

     

    1. Capitalized
      terms used herein and not defined herein shall have the meanings assigned to
      such terms in the Agreement. 

    

    2. Article
      VIII of the Agreement is hereby amended effective as of the date hereof by
      deleting in their entirety the first and third paragraphs of Section 8.12(b)
      and
      replacing them with the following:

     

    (b) Within
      fifteen days after each Distribution Date (subject to permitted extensions
      under
      the Exchange Act), the Securities Administrator shall prepare and file, and
      the
      Master Servicer shall sign on behalf of the Trust and file with the Commission
      any distribution report on Form 10-D required by the Exchange Act, in form
      and
      substance as required by the Exchange Act. The Securities Administrator shall
      file each Form 10-D with a copy of the related 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
      S
      hereto and the Securities Administrator shall compile such disclosure pursuant
      to the following paragraph. The Securities Administrator will have no duty
      or
      liability for any failure hereunder to determine or prepare any Additional
      Form
      10-D Disclosure, except as set forth in the next paragraph.

     

    After
      preparing the Form 10-D, the Securities Administrator shall forward
      electronically a draft copy of the Form 10-D to the Depositor for review. No
      later than two Business Days following the tenth calendar day after the related
      Distribution Date, a duly authorized representative of the Master Servicer
      in
      charge of the master servicing function shall sign the Form 10-D and return
      such
      signed Form 10-D to the Securities Administrator and Depositor, and no later
      than 5:00 p.m. New York City time on the fifteenth calendar day after such
      Distribution Date the Securities Administrator shall file such Form 10-D with
      the Commission. If a Form 10-D cannot be filed on time or if a previously filed
      Form 10-D needs to be amended, the Securities Administrator will follow the
      procedures set forth in Section 8.12(f)(ii). Promptly (but no later than one
      Business Day) after filing with the Commission, the Securities Administrator
      will make available on its internet website (located at www.ctslink.com)
      a final
      executed copy of each Form 10-D prepared by the Securities Administrator. The
      signing party at the Master Servicer can be contacted at 9062 Old Annapolis
      Road, Columbia, Maryland 21045-1951, Attention: Corporate Trust, GSAMP 2006-S4.
      Each party to this Agreement acknowledges that the performance by the Securities
      Administrator of its duties under this Section 8.12(b) related to the timely
      preparation and filing of the Form 10-D is contingent upon such parties strictly
      observing all applicable deadlines in the performance of their duties under
      this
      Section 8.12(b). The Securities Administrator shall have no liability for any
      loss, expense, damage or claim arising out of or with respect to any failure
      to
      properly prepare and/or timely file such Form 10-D, where such failure results
      from the Securities Administrator’s inability or failure to obtain or receive on
      a timely basis, any information from any party hereto (other than the Securities
      Administrator or any Subcontractor utilized by the Securities Administrator)
      needed to prepare, arrange for execution or file such Form 10-D, not resulting
      from its own negligence, bad faith or willful misconduct.

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    

    IN
      WITNESS WHEREOF, the Depositor, the Servicers, the Master Servicer, the
      Securities Administrator and the Trustee have caused their names to be signed
      hereto by their respective officers thereunto duly authorized as of the day
      and
