    This
      Pooling And Servicing Agreement, dated as of June 1, 2007, among IndyMac MBS,
      Inc., a Delaware corporation, as depositor (the
“Depositor”), IndyMac Bank,
      F.S.B.  (“IndyMac”), a federal savings bank,
      as seller (in that capacity, the “Seller”) and as
      servicer (in that capacity, the “Servicer”), and
      Deutsche Bank National Trust Company, a national banking association, as trustee
      (the “Trustee”),

     

    W
      i t n e s s e t h  T h a t

     

    In
      consideration of the mutual agreements set forth in this Agreement, the parties
      agree as follows:

     

    P
      r e l i m i n a r y  S t a t e m e n t

     

    The
      Depositor is the owner of the Trust Fund that is hereby conveyed to the Trustee
      in return for the Certificates.  As provided in this Agreement, the
      Trustee shall elect that the Trust Fund (exclusive of any amounts in respect
      of
      waived Prepayment Charges paid by the Servicer to the Class P Certificates
      pursuant to Section 3.20(b) and any amounts in respect of waived Late Payment
      Fees paid by the Servicer to the Class L Certificates pursuant to Section
      3.21(b)) be treated for federal income tax purposes as comprising two real
      estate mortgage investment conduits (each, a “REMIC”
or, in the alternative, “REMIC 1” and the
“Master
      REMIC”).  Each Certificate, other
      than the Class A-R and Class L Certificates, will represent ownership of one
      or
      more regular interests in the Master REMIC for purposes of the REMIC
      Provisions.  The Class A-R represents ownership of the sole class of
      residual interest in each REMIC described in this Agreement.  The
      Master REMIC will hold as assets the several classes of uncertificated REMIC
      1
      Interests (other than the Class R-1 Interest).  REMIC 1 will hold as
      assets all property of the Trust Fund.  Each REMIC 1 Interest (other
      than the Class R-1 Interest) is hereby designated as a regular interest in
      REMIC
      1.  The latest possible maturity date of all REMIC regular interests
      created in this Agreement shall be the Latest Possible Maturity
      Date.  All amounts in respect of waived Prepayment Charges paid by the
      Servicer to the Class P Certificates pursuant to Section 3.20(b) will be treated
      as paid directly by the Servicer to the Class P Certificates and not as paid
      by

    _______________

    (1)
      Each
      Class A Interest will have a principal balance initially equal to 0.9% of the
      Assumed Balance of its corresponding Loan Group. Each Class B Interest will
      have
      a principal balance initially equal to 0.1% of the the Assumed Balance of its
      corresponding Loan Group. The initial principal balance of each Class C Interest
      will equal the excess of the initial aggregate principal balance of its
      corresponding Loan Group over the initial aggregate principal balances of the
      Class A and Class B Interests (and of the Class  1-$100 Interest, in
      the case of the Class C-1 Interest) corresponding to such Loan
      Group.

     

    (2)
      The
      Weighted Average Adjusted Net Mortgage Rate of the Mortgage Loans in the
      corresponding Loan Group.

     

    (3)
      The
      Class 1-P Interests will not bear interest.  The Class 1-P Interests
      will be entitled to 100% of any Prepayment Charges paid on the Mortgage
      Loans.

     

    (4)
      The
      Weighted Average Adjusted Net Mortgage Rate of Mortgage Loans in Loan Group
      1.

     

    (5)
      The
      Class R-1 Interest is the sole class of residual interest in REMIC 1. It has
      no
      principal balance and pays no principal or interest.

     

    On
      each
      Distribution Date, the Available Funds shall be distributed with respect to
      the
      REMIC 1 Interests in the following manner:

     

    (1)
      Interest is to be distributed with respect to each REMIC 1 Interest according
      to
      the formulas described above;

     

    (2)           Principal
      Amounts and Realized Losses will be allocated to make the balances of the Class
      1-P and Class 1-$100 Interest equal to the principal balances of the Class
      P and
      Class A-R Certificates, respectively, for such Distribution Date.

     

    (3)
      If
      Cross-Over Situation does not exist with respect to any Class of Interests,
      then
      Principal Amounts and Realized Losses arising with respect to each Loan Group
      will be allocated: first to cause the Loan Group's corresponding Class A and
      Class B Interest to equal, respectively, 0.9% of the Assumed Balance and 0.1%
      of
      the Assumed Balance; and second to the Loan Group’s corresponding Class C
      Interest;

     

    (4)
      If a
      Cross-Over Situation exists with respect to the Class A and Class B Interests
      then:

     

    (a)
      if
      the Calculation Rate in respect of the outstanding Class A and Class B Interests
      is less than the Subordinate Pass-Through Rate, Principal Relocation Payments
      will be made proportionately to the outstanding Class A Interests prior to
      any
      other distributions of principal from each such Loan Group; and

     

    (b)
      if
      the Calculation Rate in respect of the outstanding Class A and Class B Interests
      is greater than the Subordinate Pass-Through Rate, Principal Relocation Payments
      will be made proportionately to the outstanding Class B Interests prior to
      any
      other distributions of principal from each such Loan Group.

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    In
      case
      of either (a) or (b), Principal Relocation Payments will be made so as to cause
      the Calculation Rate in respect of the outstanding Class A and Class B Interests
      to equal the Subordinate Pass-Through Rate. With respect to each Loan Group,
      if
      (and to the extent that) the sum of (a) the principal payments comprising the
      Principal Amount received during the Due Period and (b) the Realized Losses
      on
      the Mortgage Loans in that Loan Group, are insufficient to make the necessary
      reductions of principal on the Class A and Class B Interests, then interest
      will
      be added to the Loan Group's other REMIC 1 Interests that are not receiving
      Principal Relocation Payments, in proportion to their principal
      balances.

     

    (c)
      Unless otherwise required to achieve the Calculation Rate, the outstanding
      aggregate Class A and Class B Interests for all Loan Groups will not be reduced
      below 1% of the excess of (i) the aggregate Stated Principal Balances of the
      Mortgage Loans as of the end of any Due Period (reduced by any Principal
      Prepayments received after the Due Period that are to be distributed on the
      Distribution Date related to the Due Period)over (ii) the Certificate Balance
      of
      the Senior Certificates (excluding the Class A-R Certificates) for all
      Certificate Groups as of the related Distribution Date (after taking into
      account distributions of principal on such Distribution Date).

     

    If
      (and
      to the extent that) the limitation in paragraph (c) prevents the distribution
      of
      principal to the Class A and Class B Interests of a Loan Group, and if the
      Loan
      Group's Class C Interest has already been reduced to zero, then the excess
      principal from that Loan Group will be paid to the Class C Interests of the
      other Loan Group, the aggregate Class A and Class B Interests of which are
      less
      than 1% of the Assumed Balance.  If the Mortgage Loans in the Loan
      Group of the Class C Interest that receives such payment has a Weighted Average
      Adjusted Net Mortgage Rate below the Weighted Average Adjusted Net Mortgage
      Rate
      of the Loan Group making the payment, then the payment will be treated by the
      REMIC 1 as a Realized Loss. Conversely, if the Mortgage Loans in the Loan Group
      of the Class C Interest that receives such payment has a Weighted Average
      Adjusted Net Mortgage Rate above the Weighted Average Adjusted Net Mortgage
      Rate
      of the Mortgage Loans in the Loan Group making the payment, then the payment
      will be treated by the REMIC 1 as a reimbursement for prior Realized
      Losses.

                this

                Payment Fees collected.  For federal income tax purposes, the

                the
                Holders of the Class L Certificates and shall treat such portion
                of the
                Trust Fund as an interest in a “trust” within the meaning of Treasury
                Regulations section 301.7701-4(a) (the “Grantor Trust”).  The
                Class L Certificate shall be issued as a single

    The
      foregoing REMIC structure is intended to cause all of the cash from the Mortgage
      Loans to flow through to the Master REMIC as cash flow on a REMIC regular
      interest, without creating any shortfall—actual or potential (other than for
      credit losses) to any REMIC regular interest.

     

    For
      any
      purpose for which the Pass-Through Rates is calculated, the interest rate on
      the
      Mortgage Loans shall be appropriately adjusted to account for the difference
      between the monthly day count convention of the Mortgage Loans and the monthly
      day count convention of the regular interests issued by each of the
      REMICs.  For purposes of calculating the Pass-Through Rates for each
      of the interests issued by REMIC 1 and the Master REMIC such rates shall be
      adjusted to equal a monthly day count convention based on a 30 day month for
      each Due Period and a 360-day year so that the Mortgage Loans and all regular
      interests will be using the same monthly day count convention.

      the related Senior Percentage for that Distribution Date and (y) after the
      Distribution Date in June 2010, the Aggregate Subordinated Percentage is at
      least 200% of the Aggregate Subordinated Percentage as of the Closing Date,

      month preceding the month of such Distribution Date, the lesser of (x) the
      related Senior Percentage of the Stated Principal Balance of such Mortgage
      Loan
      and (y) either (A) if no Excess Losses were sustained on the Liquidated Mortgage
      Loan during the preceding calendar month, the related Senior Prepayment
      Percentage of the amount of the Liquidation Proceeds allocable to principal

      respect to such Liquidated Mortgage Loan during such preceding calendar month,
      the Senior Percentage of the amount of the Liquidation Proceeds allocable to
      principal received with respect to such Mortgage Loan, and (iii) the sum of
      (x)
      the Senior Prepayment Percentage of the amounts described in clause (f) of
      the
      definition of Principal Amount for that Loan Group and such Distribution Date,
      and (y) the applicable Senior Prepayment Percentage of any Subsequent Recoveries
      described in clause (g) of the definition of Principal Amount for that Loan
      Group and such Distribution Date; provided, however, that if a Bankruptcy Loss
      that is an Excess Loss is sustained with respect to a Mortgage Loan in that
      Loan
      Group that is not a Liquidated Mortgage Loan, the Senior Principal Distribution
      Amount will be reduced on the related Distribution Date by the Senior Percentage
      of the applicable principal portion of such Bankruptcy Loss; provided further,
      however, on any Distribution Date after the second Senior Termination Date,
      the
      Senior Principal Distribution Amount for the remaining Senior Certificate Group
      will be calculated pursuant to the above formula based on all the Mortgage
      Loans
      in the Mortgage Pool, as opposed to the Mortgage Loans in the related Loan
      Group.

    Except
      as
      otherwise expressly provided in this Agreement or unless the context clearly
      requires otherwise

     

    (a)  References
      to designated articles, sections, subsections, exhibits, and other subdivisions
      of this Agreement, such as “Section 6.12 (a),” refer to the designated article,
      section, subsection, exhibit, or other subdivision of this Agreement as a whole
      and to all subdivisions of the designated article, section, subsection, exhibit,
      or other subdivision.  The words “herein,” “hereof,” “hereto,”
“hereunder,” and other words of similar import refer to this Agreement as a
      whole and not to any particular article, section, exhibit, or other subdivision
      of this Agreement.

     

    (b)  Any
      term
      that relates to a document or a statute, rule, or regulation includes any

    (c)  Any
      party
      may execute any of the requirements under this Agreement either directly or
      through others, and the right to cause something to be done rather than doing
      it
      directly shall be implicit in every requirement under this
      Agreement.  Unless a provision is restricted as to time or limited as
      to frequency, all provisions under this Agreement are implicitly available
      and
      things may happen from time to time.

    (d)  The
      term
“including” and all its variations mean “including but not limited to.” Except
      when used in conjunction with the word “either,” the word “or” is always used
      inclusively (for example, the phrase “A or B” means “A or B or both,” not
“either A or B but not both”).

     

    (e)  A
      reference to “a [thing]” or “any [of a thing]” does not imply the existence or
      occurrence of the thing referred to even though not followed by “if any,” and
“any [of a thing]” is any of it.  A reference to the plural of
      anything as to which there could be either one or more than one does not imply
      the existence of more than one (for instance, the phrase “the obligors on a
      note” means “the obligor or obligors on a note”).  “Until [something
      occurs]” does not imply that it must occur, and will not be modified by the word
“unless.” The word “due” and the word “payable” are each used in the sense that
      the stated time for payment has passed.  The word “accrued” is used in
      its accounting sense, i.e., an amount paid is no longer accrued.  In
      the calculation of amounts of things, differences and sums may generally result
      in negative numbers, but when the calculation of the excess of one thing over
      another results in zero or a negative number, the calculation is disregarded
      and
      an “excess” does not exist.  Portions of things may be expressed as
      fractions or percentages interchangeably.

     

    (f)  All
      accounting terms used in an accounting context and not otherwise defined, and
      accounting terms partly defined in this Agreement, to the extent not completely
      defined, shall be construed in accordance with generally accepted accounting
      principles.  To the extent that the definitions of accounting terms in
      this Agreement are inconsistent with their meanings under generally accepted
      accounting principles, the definitions contained in this Agreement shall
      control.  Capitalized terms used in this Agreement without definition
      that are defined in the Uniform Commercial Code are used in this Agreement
      as
      defined in the Uniform Commercial Code.

     

    (g)  In
      the
      computation of a period of time from a specified date to a later specified
      date
      or an open-ended period, the words “from” and “beginning” mean “from and
      including,” the word “after” means “from but excluding,” the words “to” and
“until” mean “to but excluding,” and the word “through” means “to and
      including.” Likewise, in setting deadlines or other periods, “by” means “by.”
The words “preceding,” “following,” and words of similar import, mean
      immediately preceding or following.  References to a month or a year
      refer to calendar months and calendar years.

     

    (h)  Any
      reference to the enforceability of any agreement against a party means that
      it
      is enforceable, subject as to enforcement against the party, to applicable
      bankruptcy, insolvency, reorganization, and other similar laws of general
      applicability relating to or affecting creditors’ rights and to general equity
      principles.

    Conveyance
      Of Mortgage Loans; Representations And Warranties

     

    Section
      2.01  Conveyance
      of Mortgage Loans.

     

    (a)  The
      Seller, concurrently with the execution and delivery of this Agreement, hereby
      transfers to the Depositor, without recourse, all the interest of the Seller
      in
      each Mortgage Loan, including all interest and principal received or receivable
      by the Seller on each Mortgage Loan after the Cut-off Date and all interest
      and
      principal payments on each Mortgage Loan received before the Cut-off Date for
      installments of interest and principal due after the Cut-off Date but not
      including payments of principal and interest due by the Cut-off Date. By the
      Closing Date, the Seller shall deliver to the Depositor or, at the Depositor’s
      direction, to the Trustee or other designee of the Depositor, the Mortgage
      File
      for each  Mortgage Loan listed in the Mortgage Loan Schedule (except
      that, in the case of Mortgage Loans that are Delay Delivery Mortgage Loans,
      such
      delivery may take place within five Business Days of the Closing Date) as of
      the
      Closing Date.  The delivery of the Mortgage Files shall be made
      against payment by the Depositor of the purchase price, previously agreed to
      by
      the Seller and Depositor, for the Mortgage Loans.  With respect to any
      Mortgage Loan that does not have a first payment date on or before the Due
      Date
      in the month of the first Distribution Date, the Seller shall deposit into
      the
      Distribution Account on the first Distribution Account Deposit Date an amount
      equal to one month’s interest at the related Adjusted Mortgage Rate on the
      Cut-off Date Principal Balance of such Mortgage Loan.  Also on the
      Closing Date the Depositor shall deposit $100 into the Certificate Account
      for
      the benefit of the Class P Certificates.

     

    (b)  The
      Depositor, concurrently with the execution and delivery of this Agreement,
      hereby transfers to the Trustee for the benefit of the Certificateholders,
      without recourse, all the interest of the Depositor in the Trust Fund, together
      with the Depositor’s right to require the Seller to cure any breach of a
      representation or warranty made in this Agreement by the Seller or to repurchase
      or substitute for any affected Mortgage Loan in accordance with this
      Agreement.

     

    (c)  In
      connection with the transfer and assignment of each Mortgage Loan, the Depositor
      has delivered (or, in the case of the Delay Delivery Mortgage Loans, will
      deliver to the Trustee within the time periods specified in the definition
      of
      Delay Delivery Mortgage Loans), for the benefit of the Certificateholders the
      following documents or instruments with respect to each Mortgage Loan so
      assigned:

     

    (i)  The
      original Mortgage Note, endorsed by manual or facsimile signature in blank
      in
      the following form: “Pay to the order of _______________ ______________without
      recourse,” with all intervening endorsements showing a complete chain of
      endorsement from the originator to the Person endorsing the Mortgage Note (each
      endorsement being sufficient to transfer all interest of the party so endorsing,
      as noteholder or assignee thereof, in that Mortgage Note) or a lost note
      affidavit for any Lost Mortgage Note from the Seller stating that the original
      Mortgage Note was lost or destroyed, together with a copy of the Mortgage
      Note.

     

    (ii)  Except
      as
      provided below and for each Mortgage Loan that is not a MERS Mortgage Loan,
      the
      original recorded Mortgage or a copy of such Mortgage certified by the Seller
      as
      being a true and complete copy of the Mortgage (or, in the case of a Mortgage
      for which the related Mortgaged Property is located in the Commonwealth of
      Puerto Rico, a true copy of the Mortgage certified as such by the applicable
      notary) and in the case of each MERS Mortgage Loan, the original Mortgage,
      noting the presence of the MIN of the Mortgage Loans and either language
      indicating that the Mortgage Loan is a MOM Loan if the Mortgage Loan is a MOM
      Loan or if the Mortgage Loan was not a MOM Loan at origination, the original
      Mortgage and the assignment thereof to MERS, with evidence of recording
      indicated thereon, or a copy of the Mortgage certified by the public recording
      office in which such Mortgage has been recorded;

     

    
      
        
        

      

      
        40

        
          

        

      

      
        
        

      

    

     

    (iii)  In
      the
      case of a Mortgage Loan that is not a MERS Mortgage Loan, a duly executed
      assignment of the Mortgage (which may be included in a blanket assignment or
      assignments), together with, except as provided below, all interim recorded
      assignments of the mortgage (each assignment, when duly and validly completed,
      to be in recordable form and sufficient to effect the assignment of and transfer
      to its assignee of the Mortgage to which the assignment relates).  If
      the related Mortgage has not been returned from the applicable public recording
      office, the assignment of the Mortgage may exclude the information to be
      provided by the recording office.  The assignment of Mortgage need not
      be delivered in the case of a Mortgage for which the related Mortgage Property
      is located in the Commonwealth of Puerto Rico.

     

    (iv)  The
      original or copies of each assumption, modification, written assurance, or
      substitution agreement.

     

    (v)  Except
      as
      provided below, the original or duplicate original lender’s title policy and all
      its riders.

     

    (vi)  The
      originals of the following documents for each Cooperative Loan:

     

    
      	
              (A)    

            	
              the
                Co-op Shares, together with a stock power in
                blank;

            


    

     

    
      	
              (B)
                    

            	
              the
                executed Security Agreement;

            


    

     

    
      	
              (C)
                    

            	
              the
                executed Proprietary Lease;

            


    

     

    
      	
               
                (D)    

            	
              the
                executed Recognition Agreement;

            


    

     

    
      	
              (E)
                    

            	
              the
                executed UCC-1 financing statement that has been filed in all places
                required to perfect the Seller’s interest in the Co-op Shares and the
                Proprietary Lease with evidence of recording on it;
                and

            


    

     

    
      	
              (F)
                    

            	
              executed
                UCC-3 financing statements or other appropriate UCC financing statements
                required by state law, evidencing a complete and unbroken line from
                the
                mortgagee to the Trustee with evidence of recording thereon (or in
                a form
                suitable for recordation).

            


    

     

    In
      addition, in connection with the assignment of any MERS Mortgage Loan, the
      Seller agrees that it will cause, at the Seller’s expense, the MERS® System to
      indicate that the Mortgage Loans sold by the Seller to the Depositor have been
      assigned by the Seller to the Trustee in accordance with this Agreement for
      the
      benefit of the Certificateholders by including (or deleting, in the case of
      Mortgage Loans that are repurchased in accordance with this Agreement) in such
      computer files the information required by the MERS® System to identify the
      series of the Certificates issued in connection with such Mortgage
      Loans.  The Seller further agrees that it will not, and will not
      permit the Servicer to, and the Servicer agrees that it will not, alter the
      information referenced in this paragraph with respect to any Mortgage Loan
      sold
      by the Seller to the Depositor during the term of this Agreement unless and
      until such Mortgage Loan is repurchased in accordance with the terms of this
      Agreement.

     

    
      
        
        

      

      
        41

        
          

        

      

      
        
        

      

    

     

    In
      the
      event that in connection with any Mortgage Loan that is not a MERS Mortgage
      Loan
      the Depositor cannot deliver (a) the original recorded Mortgage, (b) all interim
      recorded assignments or (c) the lender’s title policy (together with all riders
      thereto) satisfying the requirements of clause (ii), (iii) or (v) above,
      respectively, concurrently with the execution and delivery of this Agreement
      because such document or documents have not been returned from the applicable
      public recording office in the case of clause (ii) or (iii) above, or because
      the title policy has not been delivered to either the Servicer or the Depositor
      by the applicable title insurer in the case of clause (v) above, then the
      Depositor shall promptly deliver to the Trustee, in the case of clause (ii)
      or
      (iii) above, the original Mortgage or the interim assignment, as the case may
      be, with evidence of recording indicated on when it is received from the public
      recording office, or a copy of it, certified, if appropriate, by the relevant
      recording office and in the case of clause (v) above, the original or a copy
      of
      a written commitment or interim binder or preliminary report of title issued
      by
      the title insurance or escrow company, with the original or duplicate copy
      thereof to be delivered to the Trustee upon receipt thereof.  The
      delivery of the original Mortgage Loan and each interim assignment or a copy
      of
      them, certified, if appropriate, by the relevant recording office, shall not
      be
      made later than one year following the Closing Date, or, in the case of clause
      (v) above, later than 120 days following the Closing Date.  If the
      Depositor is unable to deliver each Mortgage by that date and each interim
      assignment because any documents have not been returned by the appropriate
      recording office, or, in the case of each interim assignment, because the
      related Mortgage has not been returned by the appropriate recording office,
      the
      Depositor shall deliver the documents to the Trustee as promptly as possible
      upon their receipt and, in any event, within 720 days following the Closing
      Date.

     

    The
      Depositor shall forward to the Trustee (a) from time to time additional original
      documents evidencing an assumption or modification of a Mortgage Loan and (b)
      any other documents required to be delivered by the Depositor or the Servicer
      to
      the Trustee.  If the original Mortgage is not delivered and in
      connection with the payment in full of the related Mortgage Loan the public
      recording office requires the presentation of a “lost instruments affidavit and
      indemnity” or any equivalent document, because only a copy of the Mortgage can
      be delivered with the instrument of satisfaction or reconveyance, the Servicer
      shall execute and deliver the required document to the public recording
      office.  If a public recording office retains the original recorded
      Mortgage or if a Mortgage is lost after recordation in a public recording
      office, the Seller shall deliver to the Trustee a copy of the Mortgage certified
      by the public recording office to be a true and complete copy of the original
      recorded Mortgage.

     

    As
      promptly as practicable after any transfer of a Mortgage Loan under this
      Agreement, and in any event within thirty days after the transfer, the Trustee
      shall (i) affix the Trustee’s name to each assignment of Mortgage, as its
      assignee, and (ii) cause to be delivered for recording in the appropriate public
      office for real property records the assignments of the Mortgages to the
      Trustee, except that, if the Trustee has not received the information required
      to deliver any assignment of a Mortgage for recording, the Trustee shall deliver
      it as soon as practicable after receipt of the needed information and in any
      event within thirty days.

     

    If
      any
      Mortgage Loans have been prepaid in full as of the Closing Date, the Depositor,
      in lieu of delivering the above documents to the Trustee, will deposit in the
      Certificate Account the portion of the prepayment that is required to be
      deposited in the Certificate Account pursuant to Section 3.06.

     

    Notwithstanding
      anything to the contrary in this Agreement, within five Business Days after
      the
      Closing Date, the Seller shall either

     

    (x)           deliver
      to the Trustee the Mortgage File as required pursuant to this Section 2.01
      for
      each Delay Delivery Mortgage Loan or

     

    
      
        
        

      

      
        42

        
          

        

      

      
        
        

      

    

     

    (y)           (A)
      repurchase the Delay Delivery Mortgage Loan or (B) substitute the Substitute
      Mortgage Loan for a Delay Delivery Mortgage Loan, which repurchase or
      substitution shall be accomplished in the manner and subject to the conditions
      in Section 2.03 (treating each such Delay Delivery Mortgage Loan as a Deleted
      Mortgage Loan for purposes of such Section 2.03);

     

    provided,
      however, that if the Seller fails to deliver a Mortgage File for any
      Delay Delivery Mortgage Loan within the period specified herein, the Seller
      shall use its best reasonable efforts to effect a substitution, rather than
      a
      repurchase of, such Deleted Mortgage Loan and provided further that the cure
      period provided for in Section 2.02 or in Section 2.03 shall not apply to the
      initial delivery of the Mortgage File for such Delay Delivery Mortgage Loan,
      but
      rather the Seller shall have five (5) Business Days to cure such failure to
      deliver.  At the end of such period, the Trustee shall send a Delay
      Delivery Certification for the Delay Delivery Mortgage Loans delivered during
      such period in accordance with the provisions of Section 2.02.

     

    (d)  Notwithstanding
      the foregoing, however, the assignments of Mortgage shall not be required to
      be
      submitted for recording (except with respect to any Mortgage Loan secured by
      Mortgaged Property located in Maryland) unless such failure to record would,
      as
      certified to the Trustee in writing by the Servicer, result in a withdrawal
      or a
      downgrading by any Rating Agency of the rating on any Class of Certificates;
      provided, however, that each assignment of Mortgage shall be submitted for
      recording by the Seller (at the direction of the Servicer) in the manner
      described above, at no expense to the Trust Fund or the Trustee, upon the
      earliest to occur of: (i) reasonable direction by the Holders of Certificates
      entitled to at least 25% of the Voting Rights, (ii) the occurrence of a
      bankruptcy, insolvency or foreclosure relating to the Seller, (iii) the
      occurrence of a servicing transfer as described in Section 7.02 and (iv) if
      the
      Seller is not the Servicer and with respect to any one assignment or Mortgage,
      the occurrence of a bankruptcy, insolvency or foreclosure relating to the
      Mortgagor under the related Mortgage.  Notwithstanding the foregoing,
      if the Seller is unable to pay the cost of recording the assignments of
      Mortgage, such expense shall be paid by the Trustee and shall be reimbursable
      out of the Distribution Account.

     

    (e)   The
      Seller agrees to treat the transfer of the Mortgage Loans to the Depositor
      as a
      sale for all tax, accounting, and regulatory purposes.

     

    (f)  The
      Trust
      Fund does not intend to acquire or hold any Mortgage Loan that would violate
      the
      representations made by the Seller set forth in clause (27) of Schedule
      III.

     

    Section
      2.02  Acceptance
      by the Trustee of the Mortgage Loans.

     

    The
      Trustee acknowledges receipt of the documents identified in the Initial
      Certification in the form of Exhibit G-1, and declares that it holds and will
      hold such documents and the other documents delivered to it constituting the
      Mortgage Files for the Mortgage Loans, and that it holds or will hold such
      other
      assets as are included in the Trust Fund, in trust for the exclusive use and
      benefit of all present and future Certificateholders.

     

    The
      Trustee acknowledges that it will maintain possession of the related Mortgage
      Notes in the State of California, unless otherwise permitted by the Rating
      Agencies.  The Trustee agrees to execute and deliver on the Closing
      Date to the Depositor, the Servicer and the Seller an Initial Certification
      in
      the form of Exhibit G-1.  Based on its review and examination, and
      only as to the documents identified in such Initial Certification, the Trustee
      acknowledges that such documents appear regular on their face and relate to
      such
      Mortgage Loans.  The Trustee shall be under no duty or obligation to
      inspect, review or examine said documents, instruments, certificates or other
      papers to determine that the same are genuine, enforceable or appropriate for
      the represented purpose or that they have actually been recorded in the real
      estate records or that they are other than what they purport to be on their
      face.

     

    
      
        
        

      

      
        43

        
          

        

      

      
        
        

      

    

     

    By
      the
      thirtieth day after the Closing Date (or if that day is not a Business Day,
      the
      succeeding Business Day), the Trustee shall deliver to the Depositor, the
      Servicer, and the Seller a Delay Delivery Certification with respect to the
      Mortgage Loans substantially in the form of Exhibit G-2, with any applicable
      exceptions noted thereon.

     

    By
      the
      ninetieth day after the Closing Date (or if that day is not a Business Day,
      the
      succeeding Business Day), the Trustee shall deliver to the Depositor, the
      Servicer and the Seller a Final Certification with respect to the Mortgage
      Loans
      in the form of Exhibit H, with any applicable exceptions noted
      thereon.

     

    If,
      in
      the course of its review, the Trustee finds any document constituting a part
      of
      a Mortgage File that does not meet the requirements of Section 2.01, the Trustee
      shall list such as an exception in the Final Certification.  The
      Trustee shall not make any determination as to whether (i) any endorsement
      is
      sufficient to transfer all interest of the party so endorsing, as noteholder
      or
      assignee thereof, in that Mortgage Note or (ii) any assignment is in recordable
      form or is sufficient to effect the assignment of and transfer to the assignee
      thereof under the mortgage to which the assignment relates.  The
      Seller shall promptly correct any defect that materially and adversely affects
      the interests of the Certificateholders within 90 days from the date it was
      so
      notified of the defect and, if the Seller does not correct the defect within
      that period, the Seller shall either (a) substitute for the related Mortgage
      Loan a Substitute Mortgage Loan, which substitution shall be accomplished in
      the
      pursuant Section 2.03, or (b) purchase the Mortgage Loan at its Purchase Price
      from the Trustee within 90 days from the date the Seller was notified of the
      defect in writing.

     

    If
      a
      substitution or purchase of a Mortgage Loan pursuant to this provision is
      required because of a delay in delivery of any documents by the appropriate
      recording office, or there is a dispute between either the Servicer or the
      Seller and the Trustee over the location or status of the recorded document,
      then the substitution or purchase shall occur within 720 days from the Closing
      Date.  In no other case may a substitution or purchase occur more than
      540 days from the Closing Date.

     

    Any
      substitution pursuant to (a) above or purchase pursuant to (b) above shall
      not
      be effected before the delivery to the Trustee of the Opinion of Counsel, if
      required by Section 2.05, and any substitution pursuant to (a) above shall
      not
      be effected before the additional delivery to the Trustee of a Request for
      Release substantially in the form of Exhibit N.  No substitution is
      permitted to be made in any calendar month after the Determination Date for
      the
      month.

     

    The
      Purchase Price for any Mortgage Loan shall be deposited by the Seller in the
      Certificate Account by the Distribution Account Deposit Date for the
      Distribution Date in the month following the month of repurchase and, upon
      receipt of the deposit and certification with respect thereto in the form of
      Exhibit N, the Trustee shall release the related Mortgage File to the Seller
      and
      shall execute and deliver at the Seller’s request any instruments of transfer or
      assignment prepared by the Seller, in each case without recourse, necessary
      to
      vest in the Seller, or a designee, the Trustee’s interest in any Mortgage Loan
      released pursuant hereto.

     

    If
      pursuant to the foregoing provisions the Seller repurchases a Mortgage Loan
      that
      is a MERS Mortgage Loan, the Servicer shall either (i) cause MERS to execute
      and
      deliver an assignment of the Mortgage in recordable form to transfer the
      Mortgage from MERS to the Seller and shall cause such Mortgage to be removed
      from registration on the MERS® System in accordance with MERS’ rules and
      regulations or (ii) cause MERS to designate on the MERS® System the Seller as
      the beneficial holder of such Mortgage Loan.

    The
      Trustee shall retain possession and custody of each Mortgage File in accordance
      with and subject to the terms and conditions set forth herein.  The
      Servicer shall promptly deliver to the Trustee, upon the execution or receipt
      thereof, the originals of any other documents or instruments constituting the
      Mortgage File that come into the possession of the Servicer from time to
      time.

     

    The
      obligation of the Seller to substitute for or to purchase any Mortgage Loan
      that
      does not meet the requirements of Section 2.01 shall constitute the sole remedy
      respecting the defect available to the Trustee, the Depositor, and any
      Certificateholder against the Seller.

     

    Section
      2.03  Representations,
      Warranties, and Covenants of the Seller and the
      Servicer.

     

    (a)  IndyMac,
      in its capacities as Seller and Servicer, makes the representations and
      warranties in Schedule II, and by this reference incorporated in this Agreement,
      to the Depositor and the Trustee, as of the Closing Date.

     

    (b)  The
      Seller, in its capacity as Seller, makes the representations and warranties
      in
      Schedule III, and by this reference incorporated in this Agreement, to the
      Depositor and the Trustee, as of the Closing Date, or if so specified in
      Schedule III, as of the Cut-off Date.

     

    (c)  Upon
      discovery by any of the parties hereto of a breach of a representation or
      warranty made pursuant to Section 2.03(b) that materially and adversely affects
      the interests of the Certificateholders in any Mortgage Loan, the party
      discovering such breach shall give prompt notice thereof to the other
      parties.  Any breach of representations and warranties under clauses
      (27) and (32) of Schedule III shall be deemed to materially and adversely affect
      the interests of the Certificateholders in the affected Mortgage
      Loans.  The Seller covenants that within 90 days of the earlier of its
      discovery or its receipt of written notice from any party of a breach of any
      representation or warranty made pursuant to Section 2.03(b) which materially
      and
      adversely affects the interests of the Certificateholders in any Mortgage Loan,
      it shall cure such breach in all material respects, and if such breach is not
      so
      cured, shall, (i) if the 90-day period expires before the second anniversary
      of
      the Closing Date, remove the Mortgage Loan (a “Deleted Mortgage
      Loan”) from the Trust Fund and substitute in its place a
      Substitute Mortgage Loan, in accordance with this Section 2.03; or (ii)
      repurchase the affected Mortgage Loan or Mortgage Loans from the Trustee at
      the
      Purchase Price in the manner set forth below.  Any substitution
      pursuant to (i) above shall not be effected before the delivery to the Trustee
      of the Opinion of Counsel, if required by Section 2.05, and a Request for
      Release substantially in the form of Exhibit N, and the Mortgage File for any
      Substitute Mortgage Loan.  The Seller shall promptly reimburse the
      Servicer and the Trustee for any expenses reasonably incurred by the Servicer
      or
      the Trustee in respect of enforcing the remedies for the breach.

     

    With
      respect to any Substitute Mortgage Loan or Loans, the Seller shall deliver
      to
      the Trustee for the benefit of the Certificateholders the Mortgage Note, the
      Mortgage, the related assignment of the Mortgage, and such other documents
      and
      agreements as are required by Section 2.01, with the Mortgage Note endorsed
      and
      the Mortgage assigned as required by Section 2.01.  No substitution is
      permitted to be made in any calendar month after the Determination Date for
      such
      month.  Scheduled Payments due with respect to Substitute Mortgage
      Loans in the month of substitution shall not be part of the Trust Fund and
      will
      be retained by the Seller on the next succeeding Distribution
      Date.  For the month of substitution, distributions to
      Certificateholders will include the monthly payment due on any Deleted Mortgage
      Loan for such month and thereafter the Seller shall be entitled to retain all
      amounts received in respect of such Deleted Mortgage Loan.

     

    
      
        
        

      

      
        45

        
          

        

      

      
        
        

      

    

     

    The
      Servicer shall amend the Mortgage Loan Schedule for the benefit of the
      Certificateholders to reflect the removal of the Deleted Mortgage Loan and
      the
      substitution of the Substitute Mortgage Loans and the Servicer shall deliver
      the
      amended Mortgage Loan Schedule to the Trustee.  Upon the substitution,
      the Substitute Mortgage Loans shall be subject to this Agreement in all
      respects, and the Seller shall be deemed to have made with respect to the
      Substitute Mortgage Loans, as of the date of substitution, the representations
      and warranties made pursuant to Section 2.03(b) with respect to the Mortgage
      Loan.  Upon any substitution and the deposit to the Certificate
      Account of the amount required to be deposited therein in connection with the
      substitution as described in the following paragraph, the Trustee shall release
      the Mortgage File held for the benefit of the Certificateholders relating to
      the
      Deleted Mortgage Loan to the Seller and shall execute and deliver at the
      Seller’s direction such instruments of transfer or assignment prepared by the
      Seller, in each case without recourse, as shall be necessary to vest title
      in
      the Seller, or its designee, the Trustee’s interest in any Deleted Mortgage Loan
      substituted for pursuant to this Section 2.03.

     

    For
      any
      month in which the Seller substitutes one or more Substitute Mortgage Loans
      for
      one or more Deleted Mortgage Loans, the Servicer will determine the amount
      (if
      any) by which the aggregate principal balance of all such Substitute Mortgage
      Loans as of the date of substitution is less than the aggregate Stated Principal
      Balance of all such Deleted Mortgage Loans (after application of the scheduled
      principal portion of the monthly payments due in the month of
      substitution).  The amount of such shortage (the
“Substitution Adjustment Amount”) plus, if the Seller
      is not the Servicer, an amount equal to the aggregate of any unreimbursed
      Advances and Servicer Advances with respect to such Deleted Mortgage Loans
      shall
      be deposited into the Certificate Account by the Seller by the Distribution
      Account Deposit Date for the Distribution Date in the month succeeding the
      calendar month during which the related Mortgage Loan became required to be
      purchased or replaced hereunder.  If the Seller repurchases a Mortgage
      Loan, the Purchase Price therefor shall be deposited in the Certificate Account
      pursuant to Section 3.06 by the Distribution Account Deposit Date for the
      Distribution Date in the month following the month during which the Seller
      became obligated hereunder to repurchase or replace the Mortgage Loan and upon
      such deposit of the Purchase Price and receipt of a Request for Release in
      the
      form of Exhibit N, the Trustee shall release the related Mortgage File held
      for
      the benefit of the Certificateholders to such Person, and the Trustee shall
      execute and deliver at such Person’s direction such instruments of transfer or
      assignment prepared by such Person, in each case without recourse, as shall
      be
      necessary to transfer title from the Trustee.  The obligation under
      this Agreement of any Person to cure, repurchase, or replace any Mortgage Loan
      as to which a breach has occurred and is continuing shall constitute the sole
      remedy against the Person respecting the breach available to Certificateholders,
      the Depositor, or the Trustee on their behalf.

     

    The
      representations and warranties made pursuant to this Section 2.03 shall survive
      delivery of the respective Mortgage Files to the Trustee for the benefit of
      the
      Certificateholders and shall not be waived by the Depositor.

     

    The
      Seller assigns to the Depositor and the Depositor assigns to the Trustee all
      rights the Seller might have under contracts with third parties relating to
      early payment defaults on the Mortgage Loans (“EPD
      Rights”) and the Servicer assumes any related duties as part of
      its servicing obligations.  Consistent with the Servicing Standard,
      the Servicer shall attempt to enforce the EPD rights.  If the
      Servicer’s enforcement of the EPD Rights obligates the Servicer to sell a
      Mortgage Loan to a third party, the Servicer shall repurchase the Mortgage
      Loan
      at the Purchase Price and sell the Mortgage Loan to the third party, provided
      however, in no case shall the Servicer be obligated to repurchase a Mortgage
      Loan on account of EPD Rights unless and until the Servicer shall have
      previously received repurchase payment from a third party.  The
      Servicer shall deposit into the Certificate Account all amounts received in
      connection with the enforcement of EPD Rights, not exceeding the Purchase Price,
      with respect to any Mortgage Loan.  Any amounts received by the
      Servicer with respect a Mortgage Loan in excess of the Purchase Price shall
      be
      retained by the Servicer as additional servicing compensation. The Trustee,
      upon
      receipt of certification from the Servicer of the deposit of the Purchase Price
      in connection with a repurchase of a Mortgage Loan and a Request for File
      Release from the Servicer, shall release or cause to be released to the
      purchaser of such Mortgage Loan the related Mortgage File and shall execute
      and
      deliver such instruments of transfer or assignment prepared by the purchaser
      of
      such Mortgage Loan, in each case without recourse, as shall be necessary to
      vest
      in the purchaser of such Mortgage Loan any Mortgage Loan released pursuant
      hereto and the purchaser of such Mortgage Loan shall succeed to all the
      Trustee’s right, title and interest in and to such Mortgage Loan and all
      security and documents related thereto.  Such assignment shall be an
      assignment outright and not for security.  The purchaser of such
      Mortgage Loan shall thereupon own such Mortgage Loan, and all security and
      documents, free of any further obligation to the Trustee or the
      Certificateholders with respect thereto.

    Section
      2.04  Representations
      and Warranties of the Depositor as to the Mortgage
      Loans.

     

    The
      Depositor represents and warrants to the Trustee with respect to each Mortgage
      Loan as of the date of this Agreement or such other date set forth in this
      Agreement that as of the Closing Date, and following the transfer of the
      Mortgage Loans to it by the Seller, the Depositor had good title to the Mortgage
      Loans and the Mortgage Notes were subject to no offsets, defenses, or
      counterclaims.

     

    The
      representations and warranties in this Section 2.04 shall survive delivery
      of
      the Mortgage Files to the Trustee.  Upon discovery by the Depositor or
      the Trustee of any breach of any of the representations and warranties in this
      Section that materially and adversely affects the interest of the
      Certificateholders, the party discovering the breach shall give prompt written
      notice to the others and to each Rating Agency.

     

    Section
      2.05  Delivery
      of Opinion of Counsel in Connection with
      Substitutions.

     

    (a)  Notwithstanding
      any contrary provision of this Agreement, no substitution pursuant to Section
      2.02 or 2.03 shall be made more than 90 days after the Closing Date unless
      the
      Seller delivers to the Trustee an Opinion of Counsel, which Opinion of Counsel
      shall not be at the expense of either the Trustee or the Trust Fund, addressed
      to the Trustee, to the effect that such substitution will not (i) result in
      the
      imposition of the tax on “prohibited transactions” on the Trust Fund or
      contributions after the Startup Date, as defined in sections 860F(a)(2) and
      860G(d) of the Code, respectively or (ii) cause any REMIC created under this
      Agreement to fail to qualify as a REMIC at any time that any Certificates are
      outstanding.

     

    (b)  Upon
      discovery by the Depositor, the Seller, the Servicer or the Trustee that any
      Mortgage Loan does not constitute a “qualified mortgage” within the meaning of
      section 860G(a)(3) of the Code, the party discovering such fact shall promptly
      (and in any event within five Business Days of discovery) give written notice
      thereof to the other parties.  In connection therewith, the Trustee
      shall require the Seller, at the Seller’s option, to either (i) substitute, if
      the conditions in Section 2.03(c) with respect to substitutions are satisfied,
      a
      Substitute Mortgage Loan for the affected Mortgage Loan, or (ii) repurchase
      the
      affected Mortgage Loan within 90 days of such discovery in the same manner
      as it
      would a Mortgage Loan for a breach of representation or warranty made pursuant
      to Section 2.03.  The Trustee shall reconvey to the Seller the
      Mortgage Loan to be released pursuant hereto in the same manner, and on the
      same
      terms and conditions, as it would a Mortgage Loan repurchased for breach of
      a
      representation or warranty contained in Section 2.03.

    Section

      and Delivery of Certificates.

     

    The
      Trustee acknowledges the transfer and assignment to it of the Trust Fund and,
      concurrently with such transfer and assignment, has executed and delivered
      to or
      upon the order of the Depositor, the Certificates in authorized denominations
      evidencing directly or indirectly the entire ownership of the Trust
      Fund.  The Trustee agrees to hold the Trust Fund and exercise the
      rights referred to above for the benefit of all present and future Holders
      of
      the Certificates.

     

    Section
      2.07  REMIC
      Matters.

     

    The
      Preliminary Statement sets forth the designations and “latest possible maturity
      date” for federal income tax purposes of all interests created under this
      Agreement.  The “Startup Day” for purposes of the REMIC Provisions
      shall be the Closing Date.  Each REMIC’s fiscal year shall be the
      calendar year.

    Administration
      and Servicing of Mortgage Loans

     

    Section
      3.01  Servicer
      to Service Mortgage Loans.

     

    For
      and
      on behalf of the Certificateholders, the Servicer shall service and administer
      the Mortgage Loans in accordance with this Agreement and the Servicing
      Standard.

     

    The
      Servicer shall not make or permit any modification, waiver, or amendment of
      any
      term of any Mortgage Loan that would cause any REMIC created under this
      Agreement to fail to qualify as a REMIC or result in the imposition of any
      tax
      under section 860F(a) or section 860G(d) of the Code.

     

    Without
      limiting the generality of the foregoing, the Servicer, in its own name or
      in
      the name of the Depositor and the Trustee, is hereby authorized and empowered
      by
      the Depositor and the Trustee, when the Servicer believes it appropriate in
      its
      reasonable judgment, to execute and deliver, on behalf of the Trustee, the
      Depositor, the Certificateholders, or any of them, any instruments of
      satisfaction or cancellation, or of partial or full release or discharge, and
      all other comparable instruments, with respect to the Mortgage Loans, and with
      respect to the Mortgaged Properties held for the benefit of the
      Certificateholders.  The Servicer shall prepare and deliver to the
      Depositor or the Trustee any documents requiring execution and delivery by
      either or both of them appropriate to enable the Servicer to service and
      administer the Mortgage Loans to the extent that the Servicer is not permitted
      to execute and deliver such documents pursuant to the preceding
      sentence.  Upon receipt of the documents, the Depositor or the Trustee
      shall execute the documents and deliver them to the Servicer.

     

    The
      Servicer further is authorized and empowered by the Trustee, on behalf of the
      Certificateholders and the Trustee, in its own name, when the Servicer believes
      it appropriate in its best judgment to register any Mortgage Loan on the MERS®
System, or cause the removal from the registration of any Mortgage Loan on
      the
      MERS® System, to execute and deliver, on behalf of the Trustee and the
      Certificateholders or any of them, any and all instruments of assignment and
      other comparable instruments with respect to such assignment or re-recording
      of
      a Mortgage in the name of MERS, solely as nominee for the Trustee and its
      successors and assigns.

     

    In
      accordance with and to the extent of the Servicing Standard, the Servicer shall
      advance funds necessary to effect the payment of taxes and assessments on the
      Mortgaged Properties, which advances shall be reimbursable in the first instance
      from related collections from the Mortgagors pursuant to Section 3.07, and
      further as provided in Section 3.09.  The costs incurred by the
      Servicer in effecting the timely payments of taxes and assessments on the
      Mortgaged Properties and related insurance premiums shall not, for the purpose
      of calculating monthly distributions to the Certificateholders, be added to
      the
      Stated Principal Balances of the related Mortgage Loans, notwithstanding that
      the Mortgage Loans so permit.

     

    Nothing
      in this Agreement to the contrary shall limit the Servicer from undertaking
      any
      legal action that it may deem appropriate with respect to the Mortgage Loans
      including, without limitation, any rights or causes of action arising out of
      the
      origination of the Mortgage Loans.

    Section
      3.03  Rights
      of the Depositor and the Trustee in Respect of the
      Servicer.

     

    The
      Depositor may, but is not obligated to, enforce the obligations of the Servicer
      under this Agreement and may, but is not obligated to, perform, or cause a
      designee to perform, any defaulted obligation of the Servicer under this
      Agreement and in connection with any such defaulted obligation to exercise
      the
      related rights of the Servicer under this Agreement; provided that the Servicer
      shall not be relieved of any of its obligations under this Agreement by virtue
      of such performance by the Depositor or its designee.  Neither the
      Trustee nor the Depositor shall have any responsibility or liability for any
      action or failure to act by the Servicer nor shall the Trustee or the Depositor
      be obligated to supervise the performance of the Servicer under this Agreement
      or otherwise.

     

    Section
      3.04  [Reserved].

     

    Section
      3.05  Trustee
      to Act as Servicer.

     

    If
      the
      Servicer for any reason is no longer the Servicer under this Agreement
      (including because of the occurrence or existence of an Event of Default or
      termination by the Depositor), the Trustee or its successor shall assume all
      of
      the rights and obligations of the Servicer under this Agreement arising
      thereafter (except that the Trustee shall not be

     

    (i)  liable
      for losses of the Servicer pursuant to Section 3.10 or any acts or omissions
      of
      the predecessor Servicer hereunder,

     

    (ii)  obligated
      to make Advances if it is prohibited from doing so by applicable
      law,

     

    (iii)  obligated
      to effectuate repurchases or substitutions of Mortgage Loans hereunder,
      including repurchases or substitutions pursuant to Section 2.02 or
      2.03,

     

    (iv)  responsible
      for expenses of the Servicer pursuant to Section 2.03, or

     

    (v)  deemed
      to
      have made any representations and warranties of the Servicer
      hereunder).  Any assumption shall be subject to Section
      7.02.

     

    Notwithstanding
      anything else in this Agreement to the contrary, in no event shall the Trustee
      be liable for any servicing fee or for any differential in the amount of the
      Servicing Fee paid under this Agreement and the amount necessary to induce
      any
      successor Servicer to act as successor Servicer under this Agreement and the
      transactions provided for in this Agreement.

     

    Section
      3.06  Collection
      of Mortgage Loan Payments; Certificate Account; Distribution
      Account.

     

    (a)  In
      accordance with and to the extent of the Servicing Standard, the Servicer shall
      make reasonable efforts in accordance with the customary and usual standards
      of
      practice of prudent mortgage servicers to collect all payments called for under
      the Mortgage Loans to the extent the procedures are consistent with this
      Agreement and any related Required Insurance Policy.  Consistent with
      the foregoing, the Servicer may in its discretion (i) subject to Section 3.21,
      waive any Late Payment Fee or, subject to Section 3.20, waive any Prepayment
      Charge in connection with the prepayment of a Mortgage Loan and (ii) extend
      the
      due dates for payments due on a Delinquent Mortgage Loan for a period not
      greater than 125 days.  In connection with a seriously delinquent or
      defaulted Mortgage Loan, the Servicer may, consistent with the Servicing
      Standard, waive, modify or vary any term of that Mortgage Loan (including
      modifications  that change the Mortgage Rate, forgive the payment of
      principal or interest or extend the final maturity date of that Mortgage Loan
      ),
      accept payment from the related Mortgagor of an amount less than the Stated
      Principal Balance in final satisfaction of that Mortgage Loan, or consent to
      the
      postponement of strict compliance with any such term or otherwise grant
      indulgence to any Mortgagor if in the Servicer’s determination such waiver,
      modification, postponement or indulgence is not materially adverse to the
      interests of the Certificateholders (taking into account any estimated loss
      that
      might result absent such action) and is expected to minimize the loss on such
      Mortgage Loan; provided, however, the Servicer shall not initiate new lending
      to
      such Mortgagor through the Trust and cannot, except as provided in the
      immediately succeeding sentence, extend the maturity of any Mortgage Loan past
      the date on which the final payment is due on the latest maturing Mortgage
      Loan
      as of the Cut-off Date.  With respect to no more than 5% of the
      Mortgage Loans (measured by aggregate Cut-off Date Principal Balance of the
      Mortgage Loans), the Servicer may extend the maturity of a Mortgage Loan past
      the date on which the final payment is due on the latest maturing Mortgage
      Loan
      as of the Cut-off Date, but in no event more than one year past such date.
      In
      the event of any such arrangement, the Servicer shall make Advances on the
      related Mortgage Loan in accordance with Section 4.01 during the scheduled
      period in accordance with the amortization schedule of the Mortgage Loan without
      modification thereof because of the arrangements.  The Servicer shall
      not be required to institute or join in litigation with respect to collection
      of
      any payment (whether under a Mortgage, Mortgage Note, or otherwise or against
      any public or governmental authority with respect to a taking or condemnation)
      if it reasonably believes that enforcing the provision of the Mortgage or other
      instrument pursuant to which the payment is required is prohibited by applicable
      law.  The Servicer shall not have the discretion to sell any
      Delinquent or defaulted Mortgage Loan.

    (d)  The
      Servicer shall establish and maintain a Certificate Account into which the
      Servicer shall deposit within two Business Days of receipt or as otherwise
      specified in this Agreement, the following payments and collections received
      by
      it in respect of Mortgage Loans after the Cut-off Date (other than in respect
      of
      principal and interest due on the Mortgage Loans by the Cut-off Date) and the
      following amounts required to be deposited hereunder:

     

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

     

    (ii)  all
      payments on account of interest on the Mortgage Loans, net of Prepayment
      Interest Excess and the Servicing Fee;

     

    (iii)  all
      Insurance Proceeds, Subsequent Recoveries and Liquidation Proceeds, other than
      proceeds to be applied to the restoration or repair of the Mortgaged Property
      or
      released to the Mortgagor in accordance with the Servicer’s normal servicing
      procedures;

     

    (iv)  any
      amount required to be deposited by the Servicer pursuant to Section 3.06(f)
      in
      connection with any losses on Permitted Investments;

     

    (v)       
      any
      amounts required to be deposited by the Servicer pursuant to Sections 3.10
      and
      3.12;

     

    
      
        
        

      

      
        51

        
          

        

      

      
        
        

      

    

     

    (vi)       
      all
      Purchase Prices from the Servicer or Seller and all Substitution Adjustment
      Amounts;

     

    (vii)  all
      Advances made by the Servicer pursuant to Section 4.01;

     

    (viii)     
      any
      other
      amounts required to be deposited under this Agreement; and

     

    (ix)        
      all
      Prepayment Charges collected and amounts payable by the Servicer for the waiver
      of such amounts.

     

    In
      addition, with respect to any Mortgage Loan that is subject to a buydown
      agreement, on each Due Date for the Mortgage Loan, in addition to the monthly
      payment remitted by the Mortgagor, the Servicer shall cause funds to be
      deposited into the Certificate Account in an amount required to cause an amount
      of interest to be paid with respect to the Mortgage Loan equal to the amount
      of
      interest that has accrued on the Mortgage Loan from the preceding Due Date
      at
      the Mortgage Rate net of the Servicing Fee Rate on that date.

     

    The
      foregoing requirements for remittance by the Servicer to the Certificate Account
      shall be exclusive, it being understood and agreed that, without limiting the
      generality of the foregoing, payments in the nature of assumption fees, if
      collected, need not be remitted by the Servicer.  If the Servicer
      remits any amount not required to be remitted, it may at any time withdraw
      that
      amount from the Certificate Account, any provision in this Agreement to the
      contrary notwithstanding.  The withdrawal or direction may be
      accomplished by delivering written notice of it to the Trustee or any other
      institution maintaining the Certificate Account that describes the amounts
      deposited in error in the Certificate Account.  The Servicer shall
      maintain adequate records with respect to all withdrawals made pursuant to
      this
      Section 3.06.  All funds deposited in the Certificate Account shall be
      held in trust for the Certificateholders until withdrawn in accordance with
      Section 3.09.

     

    (e)  The
      Trustee shall establish and maintain the Distribution Account on behalf of
      the
      Certificateholders.  The Trustee shall, promptly upon receipt, deposit
      in the Distribution Account and retain in the Distribution Account the
      following:

     

    (i)  the
      aggregate amount remitted by the Servicer to the Trustee pursuant to Section
      3.09(a);

     

    (ii)     
      any
      amount deposited by the Servicer pursuant to Section 3.06(f) in connection
      with
      any losses on Permitted Investments; and

     

    (iii)    
      any
      other
      amounts deposited under this Agreement that are required to be deposited in
      the
      Distribution Account.

     

    If
      the
      Servicer remits any amount not required to be remitted, it may at any time
      direct the Trustee in writing to withdraw that amount from the Distribution
      Account, any provision in this Agreement to the contrary
      notwithstanding.  The direction may be accomplished by delivering an
      Officer’s Certificate to the Trustee that describes the amounts deposited in
      error in the Distribution Account.  All funds deposited in the
      Distribution Account shall be held by the Trustee in trust for the
      Certificateholders until disbursed in accordance with this Agreement or
      withdrawn in accordance with Section 3.09.  In no event shall the
      Trustee incur liability for withdrawals from the Distribution Account at the
      direction of the Servicer.

    (f)  Each
      institution at which the Certificate Account is maintained shall invest the
      funds in such account as directed in writing by the Servicer in Permitted
      Investments, which shall mature not later than the second Business Day preceding
      the related Distribution Account Deposit Date (except that if the Permitted
      Investment is an obligation of the institution that maintains the account,
      then
      the Permitted Investment shall mature not later than the Business Day preceding
      the Distribution Account Deposit Date) and which shall not be sold or disposed
      of before its maturity.  The funds in the Distribution Account shall
      remain uninvested.  All such Permitted Investments shall be made in
      the name of the Trustee, for the benefit of the
      Certificateholders.  All income realized from any such investment of
      funds on deposit in the Certificate Account shall be for the benefit of the
      Servicer as servicing compensation and shall be remitted to it monthly as
      provided in this Agreement.  The amount of any realized losses on
      Permitted Investments in the Certificate Account shall promptly be deposited
      by
      the Servicer in the Certificate Account.  The Trustee shall not be
      liable for the amount of any loss incurred in respect of any investment or
      lack
      of investment of funds held in the Certificate Account and made in accordance
      with this Section 3.06.

     

    (g)  The
      Servicer shall give notice to the Trustee, the Seller, each Rating Agency and
      the Depositor of any proposed change of the location of the Certificate Account
      not later than 30 days and not more than 45 days prior to any change of this
      Agreement.  The Trustee shall give notice to the Servicer, the Seller,
      each Rating Agency and the Depositor of any proposed change of the location
      of
      the Distribution Account not later than 30 days and not more than 45 days prior
      to any change of this Agreement.

     

    (h)  Upon
      a
      downgrade in the rating of an institution at which an Eligible Account is held
      below the required ratings set forth in the definition of Eligible Account,
      within 30 days of such downgrade, such account will be transferred to an account
      meeting the requirements of the definition of Eligible Account; provided,
      however, that this transfer requirement may be waived by the applicable Rating
      Agency.

     

    Section
      3.07   Collection
      of Taxes, Assessments and Similar Items; Escrow
      Accounts.

     

    (a)  To
      the
      extent required by the related Mortgage Note and not violative of current law,
      the Servicer shall establish and maintain one or more accounts (each, an
“Escrow Account”) and deposit and retain therein all
      collections from the Mortgagors (or advances) for the payment of taxes,
      assessments, hazard insurance premiums or comparable items for the account
      of
      the Mortgagors.  Nothing herein shall require the Servicer to compel a
      Mortgagor to establish an Escrow Account in violation of applicable
      law.

     

    (b)  Withdrawals
      of amounts so collected from the Escrow Accounts may be made only to effect
      timely payment of taxes, assessments, hazard insurance premiums, condominium
      or
      PUD association dues, or comparable items, to reimburse (without duplication)
      the Servicer out of related collections for any payments made pursuant to
      Section 3.01 (with respect to taxes and assessments and insurance premiums)
      and
      Section 3.10 (with respect to hazard insurance), to refund to any Mortgagors
      any
      sums determined to be overages, to pay interest, if required by law or the
      related Mortgage or Mortgage Note, to Mortgagors on balances in the Escrow
      Account or to clear and terminate the Escrow Account at the termination of
      this
      Agreement in accordance with Section 9.01.  The Escrow Accounts shall
      not be a part of the Trust Fund.

     

    (c)  The
      Servicer shall advance any payments referred to in Section 3.07(a) that are
      not
      timely paid by the Mortgagors or advanced by the Servicer on the date when
      the
      tax, premium or other cost for which such payment is intended is due, but the
      Servicer shall be required so to advance only to the extent that such advances,
      in the good faith judgment of the Servicer, will be recoverable by the Servicer
      out of Insurance Proceeds, Liquidation Proceeds or otherwise.

    Section
      3.08  Access
      to Certain Documentation and Information Regarding the Mortgage
      Loans.

     

    The
      Servicer shall afford the Depositor and the Trustee reasonable access to all
      records and documentation regarding the Mortgage Loans and all accounts,
      insurance information and other matters relating to this Agreement, such access
      being afforded without charge, but only upon reasonable request and during
      normal business hours at the office designated by the Servicer.

     

    Upon
      reasonable advance notice in writing, the Servicer will provide to each
      Certificateholder or Certificate Owner that is a savings and loan association,
      bank, or insurance company certain reports and reasonable access to information
      and documentation regarding the Mortgage Loans sufficient to permit the
      Certificateholder or Certificate Owner to comply with applicable regulations
      of
      the OTS or other regulatory authorities with respect to investment in the
      Certificates.  The Servicer shall be entitled to be reimbursed by each
      such Certificateholder or Certificate Owner for actual expenses incurred by
      the
      Servicer in providing the reports and access.

     

    Section
      3.09  Permitted
      Withdrawals from the Certificate Account and the Distribution
      Account.

     

    (a)  The
      Servicer may (and, in the case of clause (ix) below, shall) from time to time
      make withdrawals from the Certificate Account for the following
      purposes:

     

    (i)  to
      pay to
      the Servicer (to the extent not previously retained) the servicing compensation
      to which it is entitled pursuant to Section 3.15, and to pay to the Servicer,
      as
      additional servicing compensation, earnings on or investment income with respect
      to funds in or credited to the Certificate Account;

     

    (ii)     
      to
      reimburse the Servicer or successor Servicer for the unreimbursed Advances
      made
      by it, such right of reimbursement pursuant to this subclause (ii) being limited
      to amounts received on the Mortgage Loans in respect of which the Advance was
      made;

     

    (iii)    
      to
      reimburse the Servicer or successor Servicer for any Nonrecoverable Advance
      previously made by it;

     

    (iv)    
      to
      reimburse the Servicer for Insured Expenses from the related Insurance
      Proceeds;

     

    (v)  to
      reimburse the Servicer for (a) unreimbursed Servicing Advances, the Servicer’s
      right to reimbursement pursuant to this clause (a) with respect to any Mortgage
      Loan being limited to amounts received on the Mortgage Loans that represent
      late
      recoveries of the payments for which the advances were made pursuant to Section
      3.01 or Section 3.07, (b) unreimbursed Servicing Advances made in respect of
      a
      Mortgage Loan for which such Servicing Advances are not recoverable from the
      Mortgagor and (c) for unpaid Servicing Fees as provided in Section
      3.12;

     

    (vi) 
         to
      pay to
      the purchaser, with respect to each Mortgage Loan or property acquired in
      respect of such Mortgage Loan that has been purchased pursuant to Section 2.02,
      2.03, or 3.12, all amounts received thereon after the date of such
      purchase;

     

    (vii)     to
      reimburse the Seller, the Servicer, or the Depositor for expenses incurred
      by
      any of them and reimbursable pursuant to Section 6.03;

     

    
      
        
        

      

      
        54

        
          

        

      

      
        
        

      

    

     

    (viii)  to
      withdraw any amount deposited in the Certificate Account and not required to
      be
      deposited in the Certificate Account;

     

    (ix)         
      by
      the
      Distribution Account Deposit Date, to withdraw (1) the Available Funds and
      the
      Trustee Fee for the Distribution Date, to the extent on deposit and (2) the
      Prepayment Charges on deposit, and remit such amount to the Trustee for deposit
      in the Distribution Account; and

     

    (x)           to
      clear
      and terminate the Certificate Account upon termination of this Agreement
      pursuant to Section 9.01.

     

    The
      Servicer shall keep and maintain separate accounting, on a Mortgage Loan by
      Mortgage Loan basis, to justify any withdrawal from the Certificate Account
      pursuant to subclauses (i), (ii), (iv), (v), and (vi).  Before making
      any withdrawal from the Certificate Account pursuant to subclause (iii), the
      Servicer shall deliver to the Trustee an Officer’s Certificate of a Servicing
      Officer indicating the amount of any previous Advance determined by the Servicer
      to be a Nonrecoverable Advance and identifying the related Mortgage Loans and
      their respective portions of the Nonrecoverable Advance.

     

    In
      addition to the amounts remitted to the Trustee by the Servicer from the
      Certificate Account, by the Distribution Account Deposit Date, the Servicer
      shall remit all Late Payment Fees assessable and not waived pursuant to Section
      3.21(a) to the Trustee for deposit in the Distribution Account.

     

    (b)   The
      Trustee shall withdraw funds from the Distribution Account for distributions
      to
      Certificateholders in the manner specified in this Agreement (and to withhold
      from the amounts so withdrawn the amount of any taxes that it is authorized
      to
      withhold pursuant to the third paragraph of Section 8.11).  In
      addition, the Trustee may from time to time make withdrawals from the
      Distribution Account for the following purposes:

     

    (i)        
      to
      pay to
      itself the Trustee Fee for the related Distribution Date;

     

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

     

    (iii)  to
      clear
      and terminate the Distribution Account upon termination of the Agreement
      pursuant to Section 9.01.

     

    Section
      3.10  Maintenance
      of Hazard Insurance; Maintenance of Primary Insurance
      Policies.

     

    (a)    
      The
      Servicer shall maintain, for each Mortgage Loan, hazard insurance with extended
      coverage in an amount that is at least equal to the lesser of

     

    (i)           the
      maximum insurable value of the improvements securing the Mortgage Loan
      and

     

    (ii)           the
      greater of (y) the outstanding principal balance of the Mortgage Loan and (z)
      an
      amount such that the proceeds of the policy are sufficient to prevent the
      Mortgagor or the mortgagee from becoming a co-insurer.

     

    Each
      policy of standard hazard insurance shall contain, or have an accompanying
      endorsement that contains, a standard mortgagee clause.  Any amounts
      collected under the policies (other than the amounts to be applied to the
      restoration or repair of the related Mortgaged Property or amounts released
      to
      the Mortgagor in accordance with the Servicer’s normal servicing procedures)
      shall be deposited in the Certificate Account.  Any cost incurred in
      maintaining any insurance shall not, for the purpose of calculating monthly
      distributions to the Certificateholders or remittances to the Trustee for their
      benefit, be added to the principal balance of the Mortgage Loan, notwithstanding
      that the Mortgage Loan so permits.  Such costs shall be recoverable by
      the Servicer out of late payments (other than Late Payment Fees) by the related
      Mortgagor or out of Liquidation Proceeds to the extent permitted by Section
      3.09.  No earthquake or other additional insurance is to be required
      of any Mortgagor or maintained on property acquired in respect of a Mortgage
      other than pursuant to any applicable laws and regulations in force that require
      additional insurance.  If the Mortgaged Property is located at the
      time of origination of the Mortgage Loan in a federally designated special
      flood
      hazard area and the area is participating in the national flood insurance
      program, the Servicer shall maintain flood insurance for the Mortgage
      Loan.  The flood insurance shall be in an amount equal to the least of
      (i) the original principal balance of the related Mortgage Loan, (ii) the
      replacement value of the improvements that are part of the Mortgaged Property,
      and (iii) the maximum amount of flood insurance available for the related
      Mortgaged Property under the national flood insurance program.

     

    
      
        
        

      

      
        55

        
          

        

      

      
        
        

      

    

     

    If
      the
      Servicer obtains and maintains a blanket policy insuring against hazard losses
      on all of the Mortgage Loans, it shall have satisfied its obligations in the
      first sentence of this Section 3.10.  The policy may contain a
      deductible clause on terms substantially equivalent to those commercially
      available and maintained by comparable servicers.  If the policy
      contains a deductible clause and a policy complying with the first sentence
      of
      this Section 3.10 has not been maintained on the related Mortgaged Property,
      and
      if a loss that would have been covered by the required policy occurs, the
      Servicer shall deposit in the Certificate Account, without any right of
      reimbursement, the amount not otherwise payable under the blanket policy because
      of the deductible clause.  In connection with its activities as
      Servicer of the Mortgage Loans, the Servicer agrees to present, on behalf of
      itself, the Depositor, and the Trustee for the benefit of the
      Certificateholders, claims under any blanket policy.

     

    (b)  The
      Servicer shall not take any action that would result in non-coverage under
      any
      applicable Primary Insurance Policy of any loss that, but for the actions of
      the
      Servicer, would have been covered thereunder.  The Servicer shall not
      cancel or refuse to renew any Primary Insurance Policy that is in effect at
      the
      date of the initial issuance of the Certificates and is required to be kept
      in
      force hereunder unless the replacement Primary Insurance Policy for the canceled
      or non-renewed policy is maintained with a Qualified Insurer.  The
      Servicer need not maintain any Primary Insurance Policy if maintaining the
      Primary Insurance Policy is prohibited by applicable law.  The
      Servicer agrees, to the extent permitted by applicable law, to effect the timely
      payment of the premiums on each Primary Insurance Policy, and any costs not
      otherwise recoverable shall be recoverable by the Servicer from the related
      liquidation proceeds.

     

    In
      connection with its activities as Servicer of the Mortgage Loans, the Servicer
      agrees to present, on behalf of itself, the Trustee and the Certificateholders,
      claims to the insurer under any Primary Insurance Policies and, in this regard,
      to take any reasonable action in accordance with the Servicing Standard
      necessary to permit recovery under any Primary Insurance Policies respecting
      defaulted Mortgage Loans.  Any amounts collected by the Servicer under
      any Primary Insurance Policies shall be deposited in the Certificate
      Account.

     

    Section
      3.11  Enforcement
      of Due-On-Sale Clauses; Assumption Agreements.

     

    (a)  Except
      as
      otherwise provided in this Section 3.11, when any property subject to a Mortgage
      has been conveyed by the Mortgagor, the Servicer shall to the extent that it
      has
      knowledge of the conveyance and in accordance with the Servicing Standard,
      enforce any due-on-sale clause contained in any Mortgage Note or Mortgage,
      to
      the extent permitted under applicable law and governmental regulations, but
      only
      to the extent that enforcement will not adversely affect or jeopardize coverage
      under any Required Insurance Policy.  Notwithstanding the foregoing,
      the Servicer is not required to exercise these rights with respect to a Mortgage
      Loan if the Person to whom the related Mortgaged Property has been conveyed
      or
      is proposed to be conveyed satisfies the conditions contained in the Mortgage
      Note and Mortgage related thereto and the consent of the mortgagee under the
      Mortgage Note or Mortgage is not otherwise so required under the Mortgage Note
      or Mortgage as a condition to the transfer.

     

    
      
        
        

      

      
        56

        
          

        

      

      
        
        

      

    

     

    If
      (i)
      the Servicer is prohibited by law from enforcing any due-on-sale clause, (ii)
      coverage under any Required Insurance Policy would be adversely affected, (iii)
      the Mortgage Note does not include a due-on-sale clause, or (iv) nonenforcement
      is otherwise permitted hereunder, the Servicer is authorized, subject to Section
      3.11(b), to take or enter into an assumption and modification agreement from
      or
      with the person to whom the property has been or is about to be conveyed,
      pursuant to which the person becomes liable under the Mortgage Note and, unless
      prohibited by applicable state law, the Mortgagor remains liable
      thereon.  The Mortgage Loan must continue to be covered (if so covered
      before the Servicer enters into the agreement) by the applicable Required
      Insurance Policies.

     

    The
      Servicer, subject to Section 3.11(b), is also authorized with the prior approval
      of the insurers under any Required Insurance Policies to enter into a
      substitution of liability agreement with the Person, pursuant to which the
      original Mortgagor is released from liability and the Person is substituted
      as
      Mortgagor and becomes liable under the Mortgage Note.  Notwithstanding
      the foregoing, the Servicer shall not be deemed to be in default under this
      Section 3.11 because of any transfer or assumption that the Servicer reasonably
      believes it is restricted by law from preventing, for any reason
      whatsoever.

     

    (b)  Subject
      to the Servicer’s duty to enforce any due-on-sale clause to the extent set forth
      in Section 3.11(a), in any case in which a Mortgaged Property has been conveyed
      to a Person by a Mortgagor, and the Person is to enter into an assumption
      agreement or modification agreement or supplement to the Mortgage Note or
      Mortgage that requires the signature of the Trustee, or if an instrument of
      release signed by the Trustee is required releasing the Mortgagor from liability
      on the Mortgage Loan, the Servicer shall prepare and deliver to the Trustee
      for
      signature and shall direct the Trustee, in writing, to execute the assumption
      agreement with the Person to whom the Mortgaged Property is to be conveyed,
      and
      the modification agreement or supplement to the Mortgage Note or Mortgage or
      other instruments appropriate to carry out the terms of the Mortgage Note or
      Mortgage or otherwise to comply with any applicable laws regarding assumptions
      or the transfer of the Mortgaged Property to the Person.  In
      connection with any such assumption, no material term of the Mortgage Note
      may
      be changed.

     

    In
      addition, the substitute Mortgagor and the Mortgaged Property must be acceptable
      to the Servicer in accordance with its underwriting standards as then in
      effect.  Together with each substitution, assumption, or other
      agreement or instrument delivered to the Trustee for execution by it, the
      Servicer shall deliver an Officer’s Certificate signed by a Servicing Officer
      stating that the requirements of this subsection have been met in connection
      with such Officer’s Certificate.  The Servicer shall notify the
      Trustee that any substitution or assumption agreement has been completed by
      forwarding to the Trustee the original of the substitution or assumption
      agreement, which in the case of the original shall be added to the related
      Mortgage File and shall, for all purposes, be considered a part of the Mortgage
      File to the same extent as all other documents and instruments constituting
      a
      part of the Mortgage File.  The Servicer will retain any fee collected
      by it for entering into an assumption or substitution of liability agreement
      as
      additional servicing compensation.

     

    Section
      3.12  Realization
      Upon Defaulted Mortgage Loans.

     

    The
      Servicer shall use reasonable efforts in accordance with the Servicing Standard
      to foreclose on or otherwise comparably convert the ownership of assets securing
      such of the Mortgage Loans as come into and continue in default and as to which
      no satisfactory arrangements can be made for collection of delinquent
      payments.  In connection with the foreclosure or other conversion, the
      Servicer shall follow the Servicing Standard and shall follow the requirements
      of the insurer under any Required Insurance Policy.  The Servicer
      shall not be required to expend its own funds in connection with any foreclosure
      or towards the restoration of any property unless it determines (i) that the
      restoration or foreclosure will increase the proceeds of liquidation of the
      Mortgage Loan after reimbursement to itself of restoration expenses and (ii)
      that restoration expenses will be recoverable to it through Liquidation Proceeds
      (respecting which it shall have priority for purposes of withdrawals from the
      Certificate Account).  The Servicer shall be responsible for all other
      costs and expenses incurred by it in any foreclosure proceedings.  The
      Servicer is entitled to reimbursement of such costs and expenses from the
      liquidation proceeds with respect to the related Mortgaged Property, as provided
      in the definition of Liquidation Proceeds.  If the Servicer has
      knowledge that a Mortgaged Property that the Servicer is contemplating acquiring
      in foreclosure or by deed in lieu of foreclosure is located within a one mile
      radius of any site listed in the Expenditure Plan for the Hazardous Substance
      Clean Up Bond Act of 1984 or other site with environmental or hazardous waste
      risks known to the Servicer, the Servicer will, before acquiring the Mortgaged
      Property, consider the risks and only take action in accordance with its
      established environmental review procedures.

     

    
      
        
        

      

      
        57

        
          

        

      

      
        
        

      

    

     

    With
      respect to any REO Property, the deed or certificate of sale shall be taken
      in
      the name of the Trustee for the benefit of the Certificateholders, or its
      nominee, on behalf of the Certificateholders.  The Trustee’s name
      shall be placed on the title to the REO Property solely as the Trustee hereunder
      and not in its individual capacity.  The Servicer shall ensure that
      the title to the REO Property references the Pooling and Servicing Agreement
      and
      the Trustee’s capacity hereunder.  Pursuant to its efforts to sell the
      REO Property, the Servicer shall either itself or through an agent selected
      by
      the Servicer protect and conserve the REO Property in accordance with the
      Servicing Standard.

     

    The
      Servicer shall perform the tax reporting and withholding required by sections
      1445 and 6050J of the Code with respect to foreclosures and abandonments, the
      tax reporting required by section 6050H of the Code with respect to the receipt
      of mortgage interest from individuals and, if required by section 6050P of
      the
      Code with respect to the cancellation of indebtedness by certain financial
      entities, by preparing any required tax and information returns, in the form
      required.

     

    If
      the
      Trust Fund acquires any Mortgaged Property as aforesaid or otherwise in
      connection with a default or imminent default on a Mortgage Loan, the REO
      Property shall only be held temporarily, shall be actively marketed for sale,
      and the Servicer shall dispose of the Mortgaged Property as soon as practicable,
      and in any case before the end of the third calendar year following the calendar
      year in which the Trust Fund acquires the property.  Notwithstanding
      any other provision of this Agreement, no Mortgaged Property acquired by the
      Trust Fund shall be rented (or allowed to continue to be rented) or otherwise
      used for the production of income by or on behalf of the Trust
      Fund.

     

    The
      decision of the Servicer to foreclose on a defaulted Mortgage Loan shall be
      subject to a determination by the Servicer that the proceeds of the foreclosure
      would exceed the costs and expenses of bringing a foreclosure
      proceeding.  The proceeds received from the maintenance of any REO
      Properties, net of reimbursement to the Servicer for costs incurred (including
      any property or other taxes) in connection with maintenance of the REO
      Properties and net of unreimbursed Servicing Fees, Advances, and Servicing
      Advances, shall be applied to the payment of principal of and interest on the
      related defaulted Mortgage Loans (with interest accruing as though the Mortgage
      Loans were still current and adjustments, if applicable, to the Mortgage Rate
      were being made in accordance with the Mortgage Note) and all such proceeds
      shall be deemed, for all purposes in this Agreement, to be payments on account
      of principal and interest on the related Mortgage Notes and shall be deposited
      into the Certificate Account.  To the extent the net proceeds received
      during any calendar month exceeds the amount attributable to amortizing
      principal and accrued interest at the related Mortgage Rate on the related
      Mortgage Loan for the calendar month, the excess shall be considered to be
      a
      partial prepayment of principal of the related Mortgage Loan.

     

    
      
        
        

      

      
        58

        
          

        

      

      
        
        

      

    

     

    The
      proceeds from any liquidation of a Mortgage Loan, as well as any proceeds from
      an REO Property, will be applied in the following order of priority: first,
      to
      reimburse the Servicer for any related unreimbursed Servicing Advances or
      Servicing Fees or for any related unreimbursed Advances, as applicable; second,
      to reimburse the Servicer, as applicable, and to reimburse the Certificate
      Account for any Nonrecoverable Advances (or portions thereof) that were
      previously withdrawn by the Servicer pursuant to Section 3.09(a)(iii) that
      related to the Mortgage Loan; third, to accrued and unpaid interest (to the
      extent no Advance has been made for such amount or any such Advance has been
      reimbursed) on the Mortgage Loan or related REO Property, at the Adjusted Net
      Mortgage Rate to the Due Date occurring in the month in which such amounts
      are
      required to be distributed; and fourth, as a recovery of principal of the
      Mortgage Loan.  The Servicer will retain any Excess Proceeds from the
      liquidation of a Liquidated Mortgage Loan as additional servicing compensation
      pursuant to Section 3.15.

     

    The
      Servicer may agree to a modification of any Mortgage Loan at the request of
      the
      related Mortgagor if (i) the modification is in lieu of a refinancing and (ii)
      the Servicer purchases that Mortgage Loan from the Trust Fund as described
      below.  Upon the agreement of the Servicer to modify a Mortgage Loan
      in accordance with the preceding sentence, the Servicer shall purchase that
      Mortgage Loan and all interest of the Trustee in that Mortgage Loan shall
      automatically be deemed transferred and assigned to the Servicer and all
      benefits and burdens of ownership thereof, including the right to accrued
      interest thereon from the date of purchase and the risk of default thereon,
      shall pass to the Servicer.  The Servicer shall promptly deliver to
      the Trustee a certification of a Servicing Officer to the effect that all
      requirements of this paragraph have been satisfied with respect to a Mortgage
      Loan to be repurchased pursuant to this paragraph.

     

    The
      Servicer shall deposit the Purchase Price for any Mortgage Loan repurchased
      pursuant to Section 3.12 in the Certificate Account pursuant to Section 3.06
      within one Business Day after the purchase of the Mortgage Loan.  Upon
      receipt by the Trustee of written notification of any such deposit signed by
      a
      Servicing Officer, the Trustee shall release to the Servicer the related
      Mortgage File and shall execute and deliver such instruments of transfer or
      assignment, in each case without recourse, as shall be necessary to vest in
      the
      Servicer any Mortgage Loan previously transferred and assigned pursuant
      hereto.  The Servicer covenants and agrees to indemnify the Trust Fund
      against any liability for any “prohibited transaction” taxes and any related
      interest, additions, and penalties imposed on the Trust Fund established
      hereunder as a result of any modification of a Mortgage Loan effected pursuant
      to this Section, or any purchase of a Mortgage Loan by the Servicer in
      connection with a modification (but such obligation shall not prevent the
      Servicer or any other appropriate Person from contesting any such tax in
      appropriate proceedings and shall not prevent the Servicer from withholding
      payment of such tax, if permitted by law, pending the outcome of such
      proceedings).  The Servicer shall have no right of reimbursement for
      any amount paid pursuant to the foregoing indemnification, except to the extent
      that the amount of any tax, interest, and penalties, together with interest
      thereon, is refunded to the Trust Fund.

     

    Section
      3.13  Trustee
      to Cooperate; Release of Mortgage Files.

     

    Upon
      the
      payment in full of any Mortgage Loan, or the receipt by the Servicer of a
      notification that payment in full will be escrowed in a manner customary for
      such purposes, the Servicer will immediately notify the Trustee by delivering
      a
      Request for Release substantially in the form of Exhibit N.  Upon
      receipt of the request, the Trustee shall promptly release the related Mortgage
      File to the Servicer, and the Trustee shall at the Servicer’s direction execute
      and deliver to the Servicer the request for reconveyance, deed of reconveyance,
      or release or satisfaction of mortgage or such instrument releasing the lien
      of
      the Mortgage in each case provided by the Servicer, together with the Mortgage
      Note with written evidence of cancellation thereon.  The Servicer is
      authorized to cause the removal from the registration on the MERS System of
      such
      Mortgage and to execute and deliver, on behalf of the Trustee and the
      Certificateholders or any of them, any and all instruments of satisfaction
      or
      cancellation or of partial or full release.  Expenses incurred in
      connection with any instrument of satisfaction or deed of reconveyance shall
      be
      chargeable to the related Mortgagor.

    From
      time
      to time and as shall be appropriate for the servicing or foreclosure of any
      Mortgage Loan, including for such purpose collection under any policy of flood
      insurance, any fidelity bond or errors or omissions policy, or for the purposes
      of effecting a partial release of any Mortgaged Property from the lien of the
      Mortgage or the making of any corrections to the Mortgage Note or the Mortgage
      or any of the other documents included in the Mortgage File, the Trustee shall,
      upon delivery to the Trustee of a Request for Release in the form of Exhibit
      M
      signed by a Servicing Officer, release the Mortgage File to the Servicer or
      its
      designee.  Subject to the further limitations set forth below, the
      Servicer shall cause the Mortgage File or documents so released to be returned
      to the Trustee when the need therefor by the Servicer no longer exists, unless
      the Mortgage Loan is liquidated and the proceeds thereof are deposited in the
      Certificate Account, in which case the Servicer shall deliver to the Trustee
      a
      Request for Release in the form of Exhibit N, signed by a Servicing
      Officer.

     

    If
      the
      Servicer at any time seeks to initiate a foreclosure proceeding in respect
      of
      any Mortgaged Property as authorized by this Agreement, the Servicer shall
      deliver to the Trustee, for signature, as appropriate, any court pleadings,
      requests for trustee’s sale, or other documents necessary to effectuate such
      foreclosure or any legal action brought to obtain judgment against the Mortgagor
      on the Mortgage Note or the Mortgage or to obtain a deficiency judgment or
      to
      enforce any other remedies or rights provided by the Mortgage Note or the
      Mortgage or otherwise available at law or in equity.

     

    Section
      3.14  Documents,
      Records and Funds in Possession of the Servicer to be Held for the
      Trustee.

     

    The
      Servicer shall account fully to the Trustee for any funds it receives or
      otherwise collects as Liquidation Proceeds or Insurance Proceeds in respect
      of
      any Mortgage Loan.  All Mortgage Files and funds collected or held by,
      or under the control of, the Servicer in respect of any Mortgage Loans, whether
      from the collection of principal and interest payments or from Liquidation
      Proceeds, including any funds on deposit in the Certificate Account, shall
      be
      held by the Servicer for and on behalf of the Trustee and shall be and remain
      the sole and exclusive property of the Trustee, subject to the applicable
      provisions of this Agreement.  The Servicer also agrees that it shall
      not create, incur or subject any Mortgage File or any funds that are deposited
      in the Certificate Account, Distribution Account, or any Escrow Account, or
      any
      funds that otherwise are or may become due or payable to the Trustee for the
      benefit of the Certificateholders, to any claim, lien, security interest,
      judgment, levy, writ of attachment, or other encumbrance, or assert by legal
      action or otherwise any claim or right of setoff against any Mortgage File
      or
      any funds collected on, or in connection with, a Mortgage Loan, except, however,
      that the Servicer shall be entitled to set off against and deduct from any
      such
      funds any amounts that are properly due and payable to the Servicer under this
      Agreement.

     

    Section
      3.15  Servicing
      Compensation.

     

    The
      Servicer may retain or withdraw from the Certificate Account the Servicing
      Fee
      for each Mortgage Loan for the related Distribution Date.  If the
      Servicer directly services a Mortgage Loan, the Servicer may retain the
      Servicing Fee for its own account as compensation for performing
      services.  Notwithstanding the foregoing, the Servicing Fee payable to
      the Servicer shall be reduced by the lesser of the aggregate of the Prepayment
      Interest Shortfalls with respect to the Distribution Date and the aggregate
      Compensating Interest for the Distribution Date.

    Additional
      servicing compensation in the form of Excess Proceeds, Prepayment Interest
      Excess, assumption fees and all income net of any losses realized from Permitted
      Investments shall be retained by the Servicer to the extent not required to
      be
      deposited in the Certificate Account pursuant to Section 3.06.  The
      Servicer shall be required to pay all expenses incurred by it in connection
      with
      its servicing activities hereunder (including the payment of any premiums for
      hazard insurance, and any Primary Insurance Policy and maintenance of the other
      forms of insurance coverage required by this Agreement) and shall not be
      entitled to reimbursement therefor except as specifically provided in this
      Agreement.

     

    Section
      3.16  Access
      to Certain Documentation.

     

    The
      Servicer shall provide to the OTS and the FDIC and to comparable regulatory
      authorities supervising Holders of Certificates and Certificate Owners and
      the
      examiners and supervisory agents of the OTS, the FDIC, and such other
      authorities, access to the documentation regarding the Mortgage Loans required
      by applicable regulations of the OTS and the FDIC.  Access shall be
      afforded without charge, but only upon reasonable prior written request and
      during normal business hours at the offices designated by the
      Servicer.  Nothing in this Section 3.16 shall limit the obligation of
      the Servicer to observe any applicable law prohibiting disclosure of information
      regarding the Mortgagors and the failure of the Servicer to provide access
      as
      provided in this Section 3.16 as a result of such obligation shall not
      constitute a breach of this Section 3.16.

     

    Section
      3.17  Annual
      Statement as to Compliance.

     

    (a)  By
      March
      15 of each year, commencing with 2008, the Servicer shall deliver to the Trustee
      via electronic mail (DBSEC.Notifications@db.com) and the Depositor an Officer’s
      Certificate signed by two Servicing Officers stating, as to each signer thereof,
      that (i) a review of the activities of the Servicer during the preceding
      calendar year (or applicable portion thereof) and of the performance of the
      Servicer under this Agreement has been made under such officer’s supervision,
      and (ii) to the best of such officer’s knowledge, based on the review, the
      Servicer has fulfilled all its obligations under this Agreement, in all material
      respects throughout the year (or applicable portion thereof), or, if there
      has
      been a failure to fulfill any obligation in any material respect, specifying
      each failure known to the officer and the nature and status
      thereof.

     

    (b)  [Reserved].

     

    (c)  Copies
      of
      such statement shall be provided by the Trustee to any Certificateholder or
      Certificate Owner upon request at the Servicer’s expense, provided such
      statement is delivered by the Servicer to the Trustee.

     

    Section
      3.18  Errors
      and Omissions Insurance; Fidelity Bonds.

     

    The
      Servicer shall obtain and maintain in force (a) policies of insurance covering
      errors and omissions in the performance of its obligations as Servicer hereunder
      and (b) a fidelity bond covering its officers, employees, and
      agents.  Each policy and bond shall, together, comply with the
      requirements from time to time of FNMA or FHLMC for persons performing servicing
      for mortgage loans purchased by FNMA or FHLMC.  If any policy or bond
      ceases to be in effect, the Servicer shall obtain a comparable replacement

    Section
      3.19  Notification
      of Adjustments.

     

    On
      each
      Adjustment Date, the Servicer shall make interest rate adjustments for each
      Mortgage Loan in compliance with the requirements of the related Mortgage and
      Mortgage Note and applicable regulations.  The Servicer shall execute
      and deliver the notices required by each Mortgage and Mortgage Note and
      applicable regulations regarding interest rate adjustments.  The
      Servicer also shall provide timely notification to the Trustee of all applicable
      data and information regarding such interest rate adjustments and the Servicer’s
      methods of implementing such interest rate adjustments.  Upon the
      discovery by the Servicer or the Trustee that the Servicer has failed to adjust
      or has incorrectly adjusted a Mortgage Rate or a monthly payment pursuant to
      the
      terms of the related Mortgage Note and Mortgage, the Servicer shall immediately
      deposit in the Certificate Account from its own funds the amount of any loss
      caused thereby without reimbursement therefor; provided, however, the Servicer
      shall not be liable with respect to any interest rate adjustments made by any
      servicer prior to the Servicer.

     

    Section
      3.20  Prepayment
      Charges.

     

    (a)  The
      Servicer will not waive any part of any Prepayment Charge unless the waiver
      relates to a default or a reasonably foreseeable default, the Prepayment Charge
      would cause an undue hardship to the related borrower, the Mortgaged Property
      is
      sold by the Mortgagor, the collection of any Prepayment Charge would violate
      any
      relevant law or regulation or the waiving of the Prepayment Charge would
      otherwise benefit the Trust Fund and it is expected that the waiver would
      maximize recovery of total proceeds taking into account the value of the
      Prepayment Charge and related Mortgage Loan and doing so is standard and
      customary in servicing similar Mortgage Loans (including any waiver of a
      Prepayment Charge in connection with a refinancing of a Mortgage Loan that
      is
      related to a default or a reasonably foreseeable default).  The
      Servicer will not waive a Prepayment Charge in connection with a refinancing
      of
      a Mortgage Loan that is not related to a default or a reasonably foreseeable
      default.

     

    (b)  If
      a
      Prepayment Charge is waived other than as permitted by the prior paragraph,
      then
      the Servicer is required to pay the amount of such waived Prepayment Charge,
      for
      the benefit of the Holders of the Class P Certificates, by depositing such
      amount into the Distribution Account from its own funds, without any right
      of
      reimbursement therefor, together with and at the time that the amount prepaid
      on
      the related Mortgage Loan is required to be deposited into the Distribution
      Account.

     

    (c)  The
      Seller represents and warrants to the Depositor and the Trustee, as of the
      Closing Date, that the information in the Prepayment Charge Schedule (including
      the attached prepayment charge summary) is complete and accurate in all material
      respects at the dates as of which the information is furnished and each
      Prepayment Charge is permissible and enforceable in accordance with its terms
      under applicable state law, except as the enforceability thereof is limited
      due
      to acceleration in connection with a foreclosure or other involuntary
      payment.

     

    (d)  Upon
      discovery by the Servicer or a Responsible Officer of the Trustee (provided,
      however, that the Trustee shall have no obligation to conduct an independent
      investigation or inquiry in relation thereto) of a breach of the foregoing
      clause (c) that materially and adversely affects the right of the Holders of
      the
      Class P Certificates to any Prepayment Charge, the party discovering the breach
      shall give prompt written notice to the other parties.  Within 60 days
      of the earlier of discovery by the Servicer or receipt of notice by the Servicer
      of breach, the Servicer shall cure the breach in all material respects or shall
      pay into the Certificate Account the amount of the Prepayment Charge that would
      otherwise be due from the Mortgagor, less any amount representing such
      Prepayment Charge previously collected and paid by the Servicer into the
      Certificate Account.

    Section
      3.21  Late
      Payment Fees.

     

    (a)  The
      Servicer shall not waive any part of any Late Payment Fee unless (i) the
      collection of any Late Payment Fee would violate any relevant law or regulation
      or (ii) the waiving of the Late Payment Fee would otherwise benefit the Trust
      Fund and it is expected that the waiver would maximize recovery of total
      proceeds, taking into account the value of the Late Payment Fee and related
      Mortgage Loan and doing so is standard and customary in servicing similar
      Mortgage Loans (including the waiver of a Late Payment Fee in connection with
      a
      refinancing of a Mortgage Loan that is related to a default or reasonably
      foreseeable default).

     

    (b)  If
      the
      covenants made by the Servicer in clause (a) above is breached, the Servicer
      must pay into the Certificate Account prior to the Distribution Account Deposit
      Date following the end of the related Prepayment Period the amount of the waived
      Late Payment Fee.

     

    (c)  The
      Servicer shall remit Late Payment Fees assessable and not waived pursuant to
      clause (a) above in accordance with Section 3.09.

    Distributions
      and Advances by the Servicer

     

    Section
      4.01  Advances.

     

    (a)  The
      Servicer shall determine on or before each Servicer Advance Date whether it
      is
      required to make an Advance pursuant to the definition thereof.  If
      the Servicer determines it is required to make an Advance, it shall, on or
      before the Servicer Advance Date, either (i) deposit into the Certificate
      Account an amount equal to the Advance or (ii) make an appropriate entry in
      its
      records relating to the Certificate Account that any Amount Held for Future
      Distribution has been used by the Servicer in discharge of its obligation to
      make any such Advance.  Any funds so applied shall be replaced by the
      Servicer by deposit in the Certificate Account no later than the close of
      business on the next Servicer Advance Date.  The Servicer shall be
      entitled to be reimbursed from the Certificate Account for all Advances of
      its
      own funds made pursuant to this Section 4.01 as provided in Section
      3.09.  The obligation to make Advances with respect to any Mortgage
      Loan shall continue if such Mortgage Loan has been foreclosed or otherwise
      terminated and the Mortgaged Property has not been liquidated.  The
      Servicer shall inform the Trustee of the amount of the Advance to be made on
      each Servicer Advance Date no later than the second Business Day before the
      related Distribution Date.

     

    (b)  If
      the
      Servicer determines that it will be unable to comply with its obligation to
      make
      the Advances as and when described in the second sentence of Section 4.01(a),
      it
      shall use its best efforts to give written notice thereof to the Trustee (each
      such notice an “Advance Notice”; and such notice may
      be given by telecopy), not later than 3:00 P.M., New York time, on the Business
      Day immediately preceding the related Servicer Advance Date, specifying the
      amount that it will be unable to deposit (each such amount an
“Advance Deficiency”) and certifying that such Advance
      Deficiency constitutes an Advance hereunder and is not a Nonrecoverable
      Advance.  If the Trustee receives a Trustee Advance Notice on or
      before 3:00 P.M., New York time on a Servicer Advance Date, the Trustee is
      entitled to immediately terminate the Servicer under Section 7.01, and shall,
      not later than 3:00 P.M., New York time, on the related Distribution Date,
      deposit in the Distribution Account an amount equal to the Advance Deficiency
      identified in such Trustee Advance Notice unless it is prohibited from so doing
      by applicable law.  Notwithstanding the foregoing, the Trustee shall
      not be required to make such deposit if the Trustee shall have received written
      notification from the Servicer that the Servicer has deposited or caused to
      be
      deposited in the Certificate Account an amount equal to such Advance Deficiency
      by 3:00 P.M. New York time on the related Distribution Date.  If the
      Trustee has not terminated the Servicer, the Servicer shall reimburse the
      Trustee for the amount of any Advance (including interest at the Prime Rate
      on
      the day of such reimbursement published in The Wall Street Journal) on
      such amount, made by the Trustee pursuant to this Section 4.01(b) not later
      than
      the second day following the related Servicer Advance Date.  In the
      event that the Servicer does not reimburse the Trustee in accordance with the
      requirements of the preceding sentence, the Trustee shall immediately (a)
      terminate all of the rights and obligations of the Servicer under this Agreement
      in accordance with Section 7.01 and (b) subject to the limitations set forth
      in
      Section 3.05, assume all of the rights and obligations of the Servicer
      hereunder.

     

    (c)  The
      Servicer shall, not later than the close of business on the Business Day
      immediately preceding each Servicer Advance Date, deliver to the Trustee a
      report (in form and substance reasonably satisfactory to the Trustee) that
      indicates (i) the Mortgage Loans with respect to which the Servicer has
      determined that the related Scheduled Payments should be advanced and (ii)
      the
      amount of the related Scheduled Payments.  The Servicer shall deliver
      to the Trustee on the related Servicer Advance Date an Officer’s Certificate of
      a Servicing Officer indicating the amount of any proposed Advance determined
      by
      the Servicer to be a Nonrecoverable Advance.

                Pro Rata Share for such Distribution Date until the Class Certificate
                Balance thereof is reduced to zero;

            


    

     

    
      	
              (K)    

            	
              to
                the Class B-6 Certificates, an amount allocable to interest equal
                to the
                Class Optimal Interest Distribution Amount for such Class for such
                Distribution Date; and

            


    

     

    
      	
              (L)    

            	
              to

                to its
                Pro Rata Share for such Distribution Date until the Class Certificate
                Balance thereof is reduced to zero;

            


    

     

    (6)           [reserved];
      and

    


    (7)           to
      the Class A-R Certificates, any remaining funds; provided, that such amounts
      shall not include the $100 held in trust for the Class P
      Certificates.

    


    On
      each
      Distribution Date, all amounts representing Prepayment Charges received during
      the related Prepayment Period (and amounts paid by the Servicer for waiving
      them) will be distributed to the holders of the Class P
      Certificates.  On the Distribution Date immediately following the
      expiration of the latest Prepayment Charge Period of the Mortgage Loans, the
      $100 held in trust for the Class P Certificates shall be withdrawn from the
      Certificate Account and distributed to the Class P Certificates.  On
      each Distribution Date, all amounts representing Late Payment Fees assessable
      during the related Prepayment Period (and amounts paid by the Servicer for
      waiving them less any such amounts not deposited into the Distribution Account
      by the preceding Distribution Account Deposit date plus any such amounts
      deposited into the Distribution Account with respect to prior Prepayment
      Periods) will be distributed to the Holders of the Class L
      Certificates.

     

    (b)  [reserved].

     

    (c)  [reserved].

     

    (d)  On
      each
      Distribution Date, the amount referred to in clause (i) of the definition of
      Class Optimal Interest Distribution Amount for each Class of Certificates for
      such Distribution Date shall be reduced by (i) the related Class’ pro rata share
      of Net Prepayment Interest Shortfalls based on (x) with respect to a Class
      of
      Senior Certificates, the related Class Optimal Interest Distribution Amount
      and
      (y) with respect to a Class of Subordinated Certificates on and prior to the
      second Senior Termination Date, the related Assumed Interest Amount for such
      Distribution Date or after the second Senior Termination Date, the Class Optimal
      Interest Distribution Amount for such Distribution Date, in each case in the
      absence of such Net Prepayment Interest Shortfalls and (ii) the related Class’
Allocable Share of (A) after the Special Hazard Coverage Termination Date,
      with
      respect to each Mortgage Loan in the related Loan Group (or, after the Senior
      Credit Support Depletion Date, any Mortgage Loan) that became a Special Hazard
      Mortgage Loan during the calendar month preceding the month of such Distribution
      Date, the excess of one month’s interest at the Adjusted Net Mortgage Rate on
      the Stated Principal Balance of such Mortgage Loan as of the Due Date in such
      month over the amount of Liquidation Proceeds applied as interest on such
      Mortgage Loan with respect to such month, (B) after the Bankruptcy Coverage
      Termination Date, with respect to each Mortgage Loan that became subject to
      a
      Bankruptcy Loss during the calendar month preceding the month of such
      Distribution Date, the interest portion of the related Debt Service Reduction
      or
      Deficient Valuation, (C) each Relief Act Reduction for the Mortgage Loans in
      the
      related Loan Group (or, after the Senior Credit Support Depletion Date, any
      Mortgage Loan) incurred during the calendar month preceding the month of such
      Distribution Date and (D) after the Fraud Loss Coverage Termination Date, with
      respect to each Mortgage Loan in the related Loan Group (or, after the Senior
      Credit Support Depletion Date, any Mortgage Loan) that became a Fraud Loan
      during the calendar month preceding the month of such Distribution Date, the
      excess of one month’s interest at the related Adjusted Net Mortgage Rate on the
      Stated Principal Balance of such Mortgage Loan as of the Due Date in such month
      over the amount of Liquidation Proceeds applied as interest on such Mortgage
      Loan with respect to such month.

    (e)  Notwithstanding
      the priority and allocation contained in Section 4.02(a)(5), if, with respect
      to
      any Class of Subordinated Certificates, on any Distribution Date the sum of
      the
      related Class Subordination Percentages of such Class and of all Classes of
      Subordinated Certificates that have a higher numerical Class designation than
      such Class (the “Applicable Credit Support
      Percentage”) is less than the Original Applicable Credit Support
      Percentage for such Class, no distribution of Principal Prepayments on the
      Mortgage Loans will be made to any such Classes (the “Restricted
      Classes”) and the amount of such Principal Prepayments otherwise
      distributable to the Restricted Classes shall be distributed to the Classes
      of
      Subordinated Certificates having lower numerical Class designations than such
      Class, pro rata, based on their respective Class Certificate Balances
      immediately prior to such Distribution Date and shall be distributed in the
      sequential order set forth in Section 4.02(a)(5).  Notwithstanding the
      foregoing, the Class of Subordinated Certificates then outstanding with the
      lowest numerical class designation shall not be a Restricted Class.

     

    (f)  If
      the
      amount of a Realized Loss on a Mortgage Loan in a Loan Group has been reduced
      by
      application of Subsequent Recoveries with respect to such Mortgage Loan, the
      amount of such Subsequent Recoveries will be applied sequentially, in the order
      of payment priority, to increase the Class Certificate Balance of each related
      Class of Certificates to which Realized Losses have been allocated, but in
      each
      case by not more than the amount of Realized Losses previously allocated to
      that
      Class of Certificates pursuant to Section 4.05.  Holders of such
      Certificates will not be entitled to any payment in respect of the Class Optimal
      Interest Distribution Amount on the amount of such increases for any Interest
      Accrual Period preceding the Distribution Date on which such increase
      occurs.  Any such increases shall be applied to the Certificate
      Balance of each Certificate of such Class in accordance with its respective
      Percentage Interest.

     

    Section
      4.03  Cross-Collateralization;
      Adjustments to Available Funds

     

    (a)  On
      each
      Distribution Date prior to the earlier of the Senior Credit Support Depletion
      Date and the second Senior Termination Date, but after a Senior Termination
      Date, the Trustee shall distribute the principal portion of Available Funds
      on
      the Mortgage Loans relating to such Senior Certificates that will have been
      paid
      in full, to the holders of the Senior Certificates of the other Certificate
      Groups, pro rata, based on their Class Certificate Balances, provided, however,
      that the Trustee shall not make such distribution on such Distribution Date
      if
      (a) the Aggregate Subordinated Percentage for such Distribution Date is greater
      than or equal to 200% of such Aggregate Subordinated Percentage as of the
      Closing Date and (b) the average Stated Principal Balance of the Mortgage Loans
      in each Loan Group delinquent 60 days or more over the last six months, as
      a
      percentage of the aggregate Class Certificate Balance of the Subordinated
      Certificates, is less than 50%.

     

    
      
        
        

      

      
        68

        
          

        

      

      
        
        

      

    

     

    (b)  If
      on any
      Distribution Date the Class Certificate Balance of the Senior Certificates
      in a
      Loan Group is greater than the aggregate Stated Principal Balance of the
      Mortgage Loans in such Loan Group (each, an “Undercollateralized
      Group”), then the Trustee shall reduce the Available Funds of the
      other Loan Group(s) that are not undercollateralized (each, an
“Overcollateralized Group”), as follows:

     

    (i)  to
      add to
      the Available Funds of the Undercollateralized Group an amount equal to the
      lesser of (a) one month’s interest on the Transfer Payment Received of the
      Undercollateralized Group at the Weighted Average Adjusted Net Mortgage Rate
      applicable to the Undercollateralized Group and (b) Available Funds of the
      Overcollateralized Group(s) remaining after making distributions to the
      Certificates of the Overcollateralized Group(s) on such Distribution Date
      pursuant to Section 4.02; and

     

    (ii)  to
      the
      Senior Certificates of the Undercollateralized Group, to the extent of the
      principal portion of Available Funds of the Overcollateralized Group(s)
      remaining after making distributions to the Senior Certificates of the
      Overcollateralized Group(s) on such Distribution Date pursuant to Section 4.02,
      until the Class Certificate Balance of the Senior Certificates of such
      Undercollateralized Group equals the aggregate Stated Principal Balance of
      the
      Mortgage Loans in the related Loan Group.

     

    The
      portion of the payment received by the Undercollateralized Group allocable
      to
      principal is referred to as a “Transfer Payment
      Received.” The portion of the payment made by the
      Overcollateralized Group allocable to principal is referred to as a
“Transfer Payment Made.”

     

    If
      more
      than one Overcollateralized Group exists on any Distribution Date, reductions
      in
      the Available Funds of such Overcollateralized Groups to make payments required
      to be made pursuant to this Section 4.03 on such Distribution Date shall be
      made
      pro rata, based on the amount of remaining Available Funds for each such
      Overcollateralized Group.  If more than one Undercollateralized Group
      exists on any Distribution Date, the payments required to be made pursuant
      to
      this Section 4.03 on such Distribution Date shall be made pro rata, based on
      the
      amount of payments to be made to the Undercollateralized Groups.

      4.04  [Reserved].

     

    Section
      4.05  Allocation
      of Realized Losses.

     

    (a)  On
      or
      prior to each Determination Date, the Trustee shall determine the total amount
      of Realized Losses, including Excess Losses, with respect to each related
      Distribution Date.

     

    Realized
      Losses with respect to any Distribution Date shall be allocated as
      follows:

     

    (i)             [reserved];
      and

    (A)
      any
      Realized Loss (other than any Excess Loss) on the Mortgage Loans in a Loan
      Group
      shall be allocated first to the Subordinated Certificates in reverse order
      of
      their respective numerical Class designations (beginning with the Class of
      Subordinated Certificates then outstanding with the highest numerical Class
      designation) until the respective Class Certificate Balance of each such Class
      is reduced to zero, and second to the Classes of Senior Certificates of the
      related Senior Certificate Group, pro rata on the basis of their
      respective Class Certificate Balances, in each case immediately prior to the
      related Distribution Date, until the respective Class Certificate Balance of
      each such Class is reduced to zero, provided, however, that any
      Realized Losses other than Excess Losses on the Group 1 Mortgage Loans that
      would otherwise be allocated to the Class 1-A-1 Certificates will instead be
      allocated to the Class 1-A-2 Certificates until its Class Certificate Balance
      is
      reduced to zero and any Realized Losses other than Excess Losses on the Group
      2
      Mortgage Loans that would otherwise be allocated to the Class2-A-1 Certificates
      will instead be allocated to the Class 2-A-2 Certificates until its Class
      Certificate Balance is reduced to zero.

     

    (B)
      On
      each Distribution Date, Excess Losses on the Mortgage Loans in a Loan Group
      shall be allocated pro rata among the Classes of Senior Certificates of the
      related Senior Certificate Group and the Subordinated Certificates as follows:
      (i) in the case of the Senior Certificates, the Senior Percentage of such Excess
      Losses shall be allocated among the Classes of Senior Certificates in the
      related Senior Certificate Group, pro rata, on the basis of their respective
      Class Certificate Balances immediately prior to the related Distribution Date
      and (ii) in the case of the Subordinated Certificates, the Subordinated
      Percentage of such Excess Loss shall be allocated among the Classes of
      Subordinated Certificates, pro rata, based on each Class’ share of the Assumed
      Balance of the related Loan Group immediately prior to the related Distribution
      Date; provided, however, on any Distribution Date after the second Senior
      Termination Date, such Excess Losses on the Mortgage Loans in the related Loan
      Group shall be allocated to the Senior Certificates and the Subordinated
      Certificates on the basis of their respective Class Certificate Balances
      immediately prior to such Distribution Date; provided further, however, on
      any
      Distribution Date on and after the Senior Credit Support Depletion Date, any
      Excess Loss shall be allocated, pro rata, among the Classes of Senior
      Certificates based on their respective Class Certificate Balances immediately
      prior to the related Distribution Date.

     

    (b)  The
      Class
      Certificate Balance of the Class of Subordinated Certificates then outstanding
      with the highest numerical Class designation shall be reduced on each
      Distribution Date by the amount, if any, by which the aggregate Class
      Certificate Balance of all outstanding Classes of Certificates (after giving
      effect to the distribution of principal and the allocation of Realized Losses
      on
      such Distribution Date) exceeds the aggregate Stated Principal Balance of the
      Mortgage Loans as of the Due Date in the month of such Distribution Date (after
      giving effect to Principal Prepayments in the Prepayment Period related to
      such
      Due Date).

     

    (c)  Any
      Realized Loss allocated to a Class of Certificates or any reduction in the
      Class
      Certificate Balance of a Class of Certificates pursuant to Section 4.05(a)
      or
      (b) shall be allocated among the Certificates of such Class in proportion to
      their respective Certificate Balances.

     

    (d)  Any
      allocation of Realized Losses to a Certificate or any reduction in the
      Certificate Balance of a Certificate pursuant to Section 4.05(a) or (b) shall
      be
      accomplished by reducing the Certificate Balance thereof immediately following
      the distributions made on the related Distribution Date in accordance with
      the
      definition of Certificate Balance.

      the
      aggregate Stated Principal Balance of the Mortgage Loans in each Loan Group
      and
      in the aggregate that became Liquidated Mortgage Loans in the prior month and

    The
      Trustee's responsibility for disbursing the above information to the
      Certificateholders is limited to the availability, timeliness and accuracy
      of
      the information derived from the Servicer.

     

    By
      the
      Reporting Date, the Servicer shall provide to the Trustee in electronic form
      the
      information needed to determine the distributions to be made pursuant to Section
      4.02 and any other information on which the Servicer and the Trustee mutually
      agree.

     

    On
      or
      before the fifth Business Day following the end of each Prepayment Period (but
      in no event later than the third Business Day prior to the related Distribution
      Date), the Servicer shall deliver to the Trustee (which delivery may be by
      electronic data transmission) a report in substantially the form set forth
      as
      Schedule V.

     

    Within
      a
      reasonable period of time after the end of each calendar year, the Trustee

      was a Certificateholder, a statement containing the information set forth in
      clauses (a)(vii) and (a)(viii) of this Section 4.06 aggregated for such calendar
      year or applicable portion thereof during which such Person was a
      Certificateholder.  Such obligation of the Trustee shall be deemed to
      have been satisfied to the extent that substantially comparable information
      shall be provided by the Trustee pursuant to any requirements of the Code as
      from time to time in effect.

    The
      Certificates

     

    Section
      5.01  The
      Certificates.

     

    The
      Certificates shall be substantially in the forms attached hereto as
      exhibits.  The Certificates shall be issuable in registered form, in
      the minimum denominations, integral multiples of $1,000 in excess thereof
      (except that one Certificate in each Class may be issued in a different amount
      which must exceed the applicable minimum denomination) and aggregate
      denominations per Class set forth in the Preliminary Statement.

     

    Subject
      to Section 9.02 respecting the final distribution on the Certificates, on each
      Distribution Date the Trustee shall make distributions to each Certificateholder
      of record on the preceding Record Date either (x) by wire transfer in
      immediately available funds to the account of such holder at a bank or other
      entity having appropriate facilities therefor, if such Holder has so notified
      the Trustee at least five Business Days before the related Record Date or (y)
      by
      check mailed by first class mail to such Certificateholder at the address of
      such holder appearing in the Certificate Register.

     

    The
      Trustee shall execute the Certificates by the manual or facsimile signature
      of
      an authorized officer.  Certificates bearing the manual or facsimile
      signatures of individuals who were, at the time such signatures were affixed,
      authorized to sign on behalf of the Trustee shall bind the Trustee,
      notwithstanding that such individuals or any of them have ceased to be so
      authorized before the countersignature and delivery of any such Certificates
      or
      did not hold such offices at the date of such Certificate.  No
      Certificate shall be entitled to any benefit under this Agreement, or be valid
      for any purpose, unless countersigned by the Trustee by manual signature, and
      such countersignature upon any Certificate shall be conclusive evidence, and
      the
      only evidence, that such Certificate has been duly executed and delivered
      hereunder.  All Certificates shall be dated the date of their
      countersignature.  On the Closing Date, the Trustee shall countersign
      the Certificates to be issued at the direction of the Depositor, or any
      affiliate thereof.

     

    The
      Depositor shall provide the Trustee, on a continuous basis with an adequate
      inventory of Certificates to facilitate transfers.

     

    Section
      5.02  Certificate
      Register; Registration of Transfer and Exchange of
      Certificates.

     

    (a)  The
      Trustee shall maintain, in accordance with Section 5.06, a Certificate Register
      for the Trust Fund in which, subject to subsections (b) and (c) below and to
      such reasonable regulations as it may prescribe, the Trustee shall provide
      for
      the registration of Certificates and of transfers and exchanges of Certificates
      as herein provided.  Upon surrender for registration of transfer of
      any Certificate, the Trustee shall execute and deliver, in the name of the
      designated transferee or transferees, one or more new Certificates of the same
      Class and aggregate Percentage Interest.

     

    At
      the
      option of a Certificateholder, Certificates may be exchanged for other
      Certificates of the same Class in authorized denominations and evidencing the
      same aggregate Percentage Interest upon surrender of the Certificates to be
      exchanged at the office or agency of the Trustee.  Whenever any
      Certificates are so surrendered for exchange, the Trustee shall execute,
      authenticate, and deliver the Certificates that the Certificateholder making
      the
      exchange is entitled to receive.  A written instrument of transfer in
      form satisfactory to the Trustee duly executed by the holder of a Certificate
      or
      his attorney duly authorized in writing shall accompany every Certificate
      presented or surrendered for registration of transfer or exchange.

     

    
      
        
        

      

      
        74

        
          

        

      

      
        
        

      

    

     

    No
      service charge to the Certificateholders shall be made for any registration
      of
      transfer or exchange of Certificates, but 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 may be required.

     

    All
      Certificates surrendered for registration of transfer or exchange shall be
      cancelled and subsequently destroyed by the Trustee in accordance with the
      Trustee’s customary procedures.

     

    (b)  No
      transfer of a Private Certificate shall be made unless such transfer is made
      pursuant to an effective registration statement under the Securities Act and
      any
      applicable state securities laws or is exempt from the registration requirements
      under the Securities Act and such state securities laws.  If a
      transfer is to be made in reliance on an exemption from the Securities Act
      and
      such state securities laws, to assure compliance with the Securities Act and
      such state securities laws, the Certificateholder desiring to effect such
      transfer and such Certificateholder’s prospective transferee shall each certify
      to the Trustee in writing the facts surrounding the transfer in substantially
      the form set forth in Exhibit J (the “Transferor
      Certificate”) and deliver to the Trustee either (i) a letter in
      substantially the form of either Exhibit K (the “Investment
      Letter”) or Exhibit L (the “Rule 144A
      Letter”) or (ii) at the expense of the transferor, an Opinion of
      Counsel that the transfer may be made without registration under the Securities
      Act.  The Depositor shall provide to any Holder of a Private
      Certificate and any prospective transferee designated by that Holder,
      information regarding the related Certificates and the Mortgage Loans and any
      other information necessary to satisfy the condition to eligibility in Rule
      144A(d)(4) for transfer of the Certificate without registration thereof under
      the Securities Act pursuant to the registration exemption provided by Rule
      144A.  The Trustee and the Servicer shall cooperate with the Depositor
      in providing the Rule 144A information referenced in the preceding sentence,
      including providing to the Depositor such information regarding the
      Certificates, the Mortgage Loans, and other matters regarding the Trust Fund
      as
      the Depositor reasonably requests to meet its obligation under the preceding
      sentence.  Each Holder of a Private Certificate desiring to effect a
      transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor,
      the Seller, and the Servicer 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 an ERISA-Restricted Certificate shall be made unless the Trustee
      shall have received either (i) a representation from the transferee of such
      Certificate acceptable to and in form and substance satisfactory to the Trustee
      (if the Certificate is a Private Certificate, the requirement is satisfied
      only
      by the Trustee’s receipt of a representation letter from the transferee
      substantially in the form of Exhibit K or Exhibit L, and if the Certificate
      is a
      Residual Certificate, the requirement is satisfied only by the Trustee’s receipt
      of a representation letter from the transferee substantially in the form of
      Exhibit I), to the effect that (x) the transferee is not an employee benefit
      plan or arrangement subject to section 406 of ERISA or a plan subject to section
      4975 of the Code, or a person acting on behalf of any such plan or arrangement
      or using the assets of any such plan or arrangement to effect the transfer,
      or
      (y) if the ERISA-Restricted Certificate has been the subject of an
      ERISA-Qualifying Underwriting, a representation that the transferee is an
      insurance company that is purchasing such Certificate with funds contained
      in an
“insurance company general account” (as such term is defined in Section V(e) of
      Prohibited Transaction Class Exemption 95-60 (“PTCE
      95-60”) and that the purchase and holding of such Certificate
      satisfies the requirements for exemptive relief under Sections I and III of
      PTCE
      95-60, or (ii) in the case of any ERISA-Restricted Certificate presented for
      registration in the name of an employee benefit plan subject to ERISA, or a
      plan
      or arrangement subject to section 4975 of the Code (or comparable provisions
      of
      any subsequent enactments), or a trustee of any such plan or any other person
      acting on behalf of any such plan or arrangement or using such plan’s or
      arrangement’s assets, an Opinion of Counsel satisfactory to the Trustee, which
      Opinion of Counsel shall not be an expense of the Trustee, the Servicer or
      the
      Trust Fund, addressed to the Trustee and the Servicer, to the effect that the
      purchase and holding of such ERISA-Restricted Certificate will not result in
      a
      non-exempt prohibited transaction under ERISA or section 4975 of the Code and
      will not subject the Trustee or the Servicer to any obligation in addition
      to
      those expressly undertaken in this Agreement or to any liability.  For
      purposes of the preceding sentence, with respect to an ERISA-Restricted
      Certificate that is not a Residual Certificate, if the appropriate
      representation letter or Opinion of Counsel referred to in the preceding
      sentence is not furnished, the representation in clause (i) above, shall be
      deemed to have been made to the Trustee by the transferee’s (including an
      initial acquirer’s) acceptance of the ERISA-Restricted
      Certificates.  If the representation is violated, or any attempt is
      made to transfer to a plan or arrangement subject to section 406 of ERISA or
      a
      plan subject to section 4975 of the Code, or a person acting on behalf of any
      such plan or arrangement or using the assets of any such plan or arrangement,
      without the Opinion of Counsel described above, the attempted transfer or
      acquisition shall be void.

    To
      the
      extent permitted under applicable law (including ERISA), the Trustee shall
      be
      under no liability to any Person for any registration of transfer of any
      ERISA-Restricted Certificate that is in fact not permitted by this Section
      5.02(b) or for making any payments due on such Certificate to the Holder thereof
      or taking any other action with respect to such Holder under this Agreement
      so
      long as the transfer was registered by the Trustee in accordance with the
      foregoing requirements.

     

    (c)  Each
      Person who has or who acquires any Ownership Interest in a Residual Certificate
      shall be deemed by the acceptance or acquisition of such Ownership Interest
      to
      have agreed to be bound by the following provisions, and the rights of each
      Person acquiring any Ownership Interest in a Residual Certificate are expressly
      subject to the following provisions:

     

    (i)  Each
      Person holding or acquiring any Ownership Interest in a Residual Certificate
      shall be a Permitted Transferee and shall promptly notify the Trustee of any
      change or impending change in its status as a Permitted Transferee.

     

    (ii)  No
      Ownership Interest in a Residual Certificate may be registered on the Closing
      Date or thereafter transferred, and the Trustee shall not register the Transfer
      of any Residual Certificate unless, in addition to the certificates required
      to
      be delivered to the Trustee under subparagraph (b) above, the Trustee shall
      have
      been furnished with an affidavit (a “Transfer
      Affidavit”) of the initial owner or the proposed transferee in the
      form of Exhibit I.

     

    (iii)  Each
      Person holding or acquiring any Ownership Interest in a Residual Certificate
      shall agree (A) to obtain a Transfer Affidavit from any other Person to whom
      such Person attempts to Transfer its Ownership Interest in a Residual
      Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such
      Person is acting as nominee, trustee or agent in connection with any Transfer
      of
      a Residual Certificate and (C) not to Transfer its Ownership Interest in a
      Residual Certificate or to cause the Transfer of an Ownership Interest in a
      Residual Certificate to any other Person if it has actual knowledge that such
      Person is not a Permitted Transferee.

     

    (iv)  Any
      attempted or purported Transfer of any Ownership Interest in a Residual
      Certificate in violation of this Section 5.02(c) shall be absolutely null and
      void and shall vest no rights in the purported Transferee.  If any
      purported transferee shall become a Holder of a Residual Certificate in
      violation of this Section 5.02(c), then the last preceding Permitted Transferee
      shall be restored to all rights as Holder thereof retroactive to the date of
      registration of Transfer of such Residual Certificate.  The Trustee
      shall be under no liability to any Person for any registration of Transfer
      of a
      Residual Certificate that is in fact not permitted by Section 5.02(b) and this
      Section 5.02(c) or for making any payments due on such Certificate to the Holder
      thereof or taking any other action with respect to such Holder under this
      Agreement so long as the Transfer was registered after receipt of the related
      Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter
      or
      the Investment Letter.  The Trustee shall be entitled but not
      obligated to recover from any Holder of a Residual Certificate that was in
      fact
      not a Permitted Transferee at the time it became a Holder or, at such subsequent
      time as it became other than a Permitted Transferee, all payments made on such
      Residual Certificate at and after either such time.  Any such payments
      so recovered by the Trustee shall be paid and delivered by the Trustee to the
      last preceding Permitted Transferee of such Certificate.

     

    
      
        
        

      

      
        76

        
          

        

      

      
        
        

      

    

     

    (v)  The
      Depositor shall use its best efforts to make available, upon receipt of written
      request from the Trustee, all information necessary to compute any tax imposed
      under section 860E(e) of the Code as a result of a Transfer of an Ownership
      Interest in a Residual Certificate to any Holder who is not a Permitted
      Transferee.

     

    The
      restrictions on Transfers of a Residual Certificate set forth in this Section
      5.02(c) shall cease to apply (and the applicable portions of the legend on
      a
      Residual Certificate may be deleted) with respect to Transfers occurring after
      delivery to the Trustee of an Opinion of Counsel, which Opinion of Counsel
      shall
      not be an expense of the Trust Fund, the Trustee, the Seller or the Servicer,
      to
      the effect that the elimination of such restrictions will not cause any REMIC
      created under this Agreement to fail to qualify as a REMIC at any time that
      the
      Certificates are outstanding or result in the imposition of any tax on the
      Trust
      Fund, a Certificateholder or another Person.  Each Person holding or
      acquiring any Ownership Interest in a Residual Certificate hereby consents
      to
      any amendment of this Agreement which, based on an Opinion of Counsel furnished
      to the Trustee, is reasonably necessary (a) to ensure that the record ownership
      of, or any beneficial interest in, a Residual Certificate is not transferred,
      directly or indirectly, to a Person that is not a Permitted Transferee and
      (b)
      to provide for a means to compel the Transfer of a Residual Certificate which
      is
      held by a Person that is not a Permitted Transferee to a Holder that is a
      Permitted Transferee.

     

    (d)  The
      preparation and delivery of all certificates and opinions referred to above
      in
      this Section 5.02 in connection with transfer shall be at the expense of the
      parties to such transfers.

     

    (e)  Except
      as
      provided below, the Book-Entry Certificates shall at all times remain registered
      in the name of the Depository or its nominee and at all times: (i) registration
      of the Certificates may not be transferred by the Trustee except to another
      Depository; (ii) the Depository shall maintain book-entry records with respect
      to the Certificate Owners and with respect to ownership and transfers of such
      Book-Entry Certificates; (iii) ownership and transfers of registration of the
      Book-Entry Certificates on the books of the Depository shall be governed by
      applicable rules established by the Depository; (iv) the Depository may collect
      its usual and customary fees, charges and expenses from its Depository
      Participants; (v) the Trustee shall deal with the Depository, Depository
      Participants and Indirect Participants as representatives of the Certificate
      Owners of the Book-Entry Certificates for purposes of exercising the rights
      of
      holders under this Agreement, and requests and directions for and votes of
      such
      representatives shall not be deemed to be inconsistent if they are made with
      respect to different Certificate Owners; and (vi) the Trustee may rely and
      shall
      be fully protected in relying upon information furnished by the Depository
      with
      respect to its Depository Participants and furnished by the Depository
      Participants with respect to Indirect Participants and persons shown on the
      books of such Indirect Participants as direct or indirect Certificate
      Owners.

     

    All
      transfers by Certificate Owners of Book-Entry Certificates shall be made in
      accordance with the procedures established by the Depository Participant or
      brokerage firm representing the Certificate Owner.  Each Depository
      Participant shall only transfer 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.

    If
      (x)
      (i)  the Depository or the Depositor advises the Trustee in writing
      that the Depository is no longer willing or able to properly discharge its
      responsibilities as Depository, and (ii) the Trustee or the Depositor is unable
      to locate a qualified successor or (y) after the occurrence of an Event of
      Default, Certificate Owners representing at least 51% of the Certificate Balance
      of the Book-Entry Certificates together advise the Trustee and the Depository
      through the Depository Participants 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 Trustee shall notify all Certificate Owners, through
      the Depository, of the occurrence of any such event and of the availability
      of
      definitive, fully-registered Certificates (the “Definitive
      Certificates”) to Certificate Owners requesting the
      same.  Upon surrender to the Trustee of the related Class of
      Certificates by the Depository, accompanied by the instructions from the
      Depository for registration, the Trustee shall issue the Definitive
      Certificates.  Neither the Servicer, the Depositor nor the Trustee
      shall be liable for any delay in delivery of such instruction and each may
      conclusively rely on, and shall be protected in relying on, such
      instructions.  The Servicer shall provide the Trustee with an adequate
      inventory of certificates to facilitate the issuance and transfer of Definitive
      Certificates.  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 Trustee,
      to
      the extent applicable with respect to such Definitive Certificates and the
      Trustee shall recognize the Holders of the Definitive Certificates as
      Certificateholders hereunder; provided that the Trustee shall not by virtue
      of
      its assumption of such obligations become liable to any party for any act or
      failure to act of the Depository.

     

    Section
      5.03  Mutilated,
      Destroyed, Lost or Stolen Certificates.

     

    If
      (a)
      any mutilated Certificate is surrendered to the Trustee, or (b) the Trustee
      receives evidence to its satisfaction of the destruction, loss, or theft of
      any
      Certificate and the Servicer and the Trustee receive the security or indemnity
      required by them to hold each of them harmless, then, in the absence of notice
      to the Trustee that the Certificate has been acquired by a Protected Purchaser,
      and if the requirements of Section 8-406 of the UCC are met and subject to
      Section 8-405 of the UCC, the Trustee shall execute, countersign, and deliver,
      in exchange for or in lieu of any such mutilated, destroyed, lost, or stolen
      Certificate, a new Certificate of like Class, tenor, and Percentage
      Interest.  In connection with the issuance of any new Certificate
      under this Section 5.03, the Trustee may require the payment of a sum sufficient
      to cover any tax or other governmental charge that may be imposed in relation
      thereto and any other expenses (including the fees and expenses of the Trustee)
      connected therewith.  Any replacement Certificate issued pursuant to
      this Section 5.03 shall constitute complete and indefeasible evidence of
      ownership, as if originally issued, whether or not the lost, stolen, or
      destroyed Certificate is found at any time.

     

    Section
      5.04  Persons

      the Person in whose name any Certificate is registered as the owner of such
      Certificate for the purpose of receiving distributions as provided in this
      Agreement and for all other purposes whatsoever, and neither the Servicer,
      the
      Trustee nor any agent of the Servicer or the Trustee shall be affected by any
      notice to the contrary.

      5.05  Access
      to List of Certificateholders’ Names and Addresses.

     

    If
      three

      information in writing from the Trustee, (b) state that such Certificateholders
      and/or Certificate Owners desire to communicate with other Certificateholders
      and/or Certificate Owners with respect to their rights under this Agreement
      or
      under the Certificates, and (c) provide a copy of the communication which such
      Certificateholders and/or Certificate Owners propose to transmit, or if the
      Depositor or Servicer shall request such information in writing from the
      Trustee, then the Trustee shall, within ten Business Days after the receipt
      of
      such request, provide the Depositor, the Servicer or such Certificateholders
      and/or Certificate Owners at such recipients’ expense the most recent list of
      the Certificateholders of such Trust Fund held by the Trustee.  The
      Depositor and every Certificateholder and/or Certificate Owner, by receiving
      and
      holding a Certificate, agree that the Trustee shall not be held accountable
      because of the disclosure of any such information as to the list of the
      Certificateholders hereunder, regardless of the source from which such
      information was derived.

    Section
      6.01  Respective
      Liabilities of the Depositor and the Servicer.

     

    The
      Depositor and the Servicer shall each be liable in accordance with this
      Agreement only to the extent of the obligations specifically and respectively
      imposed upon and undertaken by them in this Agreement.

     

    Section
      6.02  Merger
      or Consolidation of the Depositor or the Servicer.

     

    The
      Depositor and the Servicer will each keep in full effect their existence and
      their rights and franchises as a corporation and a federal savings bank,
      respectively, under the laws of the United States or under the laws of one
      of
      the states thereof and will each 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, or any of the Mortgage Loans and to perform
      its respective duties under this Agreement.

     

    Any
      Person into which the Depositor or the Servicer may be merged or consolidated,
      or any Person resulting from any merger or consolidation to which the Depositor
      or the Servicer shall be a party, or any person succeeding to the business
      of
      the Depositor or the Servicer, shall be the successor of the Depositor or the
      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 successor
      or
      surviving Person to the Servicer shall be qualified to sell mortgage loans
      to,
      and to service mortgage loans on behalf of, FNMA or FHLMC.

     

    As
      a
      condition to the effectiveness of any merger or consolidation, at least 15
      calendar days prior to the effective date of any merger or consolidation of
      the
      Servicer, the Servicer shall provide (x) written notice to the Depositor of
      any
      successor pursuant to this Section and (y) in writing and in form and substance
      reasonably satisfactory to the Depositor, all information reasonably requested
      by the Depositor in order to comply with its reporting obligation under Item
      6.02 of Form 8-K with respect to a replacement Servicer.

     

    Section
      6.03  Limitation
      on Liability of the Depositor, the Seller, the Servicer, and
      Others.

     

    None
      of
      the Depositor, the Seller, the Servicer or any of the directors, officers,
      employees or agents of the Depositor, the Seller or the Servicer shall be under
      any liability to the Certificateholders for any action taken or for refraining
      from the taking of any action in good faith pursuant to this Agreement, or
      for
      errors in judgment; provided, however, that this provision shall not protect
      the
      Depositor, the Seller, the Servicer or any such Person against any breach of
      representations or warranties made by it herein or protect the Depositor, the
      Seller, the Servicer or any such Person from any liability which would otherwise
      be imposed by reasons of willful misfeasance, bad faith or gross negligence
      in
      the performance of duties or because of reckless disregard of obligations and
      duties hereunder.  The Depositor, the Seller, the Servicer, and any
      director, officer, employee or agent of the Depositor, the Seller or the
      Servicer may rely in good faith on any document of any kind prima facie properly
      executed and submitted by any Person respecting any matters arising
      hereunder.  The Depositor, the Seller, the Servicer, and any director,
      officer, employee or agent of the Depositor, the Seller or the Servicer shall
      be
      indemnified by the Trust Fund and held harmless against any loss, liability
      or
      expense incurred in connection with any audit, controversy or judicial
      proceeding relating to a governmental taxing authority or any legal action
      relating to this Agreement or the Certificates, other than any loss, liability
      or expense related to any specific Mortgage Loan or Mortgage Loans (except
      as
      any such loss, liability or expense shall be otherwise reimbursable pursuant
      to
      this Agreement) and any loss, liability or expense incurred because of willful
      misfeasance, bad faith or gross negligence in the performance of duties
      hereunder or because of reckless disregard of obligations and duties
      hereunder.  None of the Depositor, the Seller or the Servicer shall be
      under any obligation to appear in, prosecute or defend any legal action that
      is
      not incidental to its respective duties hereunder and which in its opinion
      may
      involve it in any expense or liability; provided, however, that any of the
      Depositor, the Seller or the Servicer may in its discretion undertake any such
      action that it may deem appropriate in respect of this Agreement and the rights
      and duties of the parties hereto and interests of the Trustee and the
      Certificateholders hereunder.  In such event, the legal expenses and
      costs of such action and any liability resulting therefrom shall be expenses,
      costs and liabilities of the Trust Fund, and the Depositor, the Seller, and
      the
      Servicer shall be entitled to be reimbursed therefor out of the Certificate
      Account.

    Section

    The
      Servicer shall not resign from the obligations and duties hereby imposed on
      it
      except (a) upon appointment of a successor servicer and receipt by the Trustee
      of a letter from each Rating Agency that such a resignation and appointment
      will
      not result in a downgrading, qualification or withdrawal of the rating of any
      of
      the Certificates or (b) upon determination that its duties under this Agreement
      are no longer permissible under applicable law.  Any such
      determination under clause (b) permitting the resignation of the Servicer shall
      be evidenced by an Opinion of Counsel to such effect delivered to the
      Trustee.  No such resignation shall become effective until the Trustee
      or a successor servicer shall have assumed the Servicer’s responsibilities,
      duties, liabilities and obligations under this Agreement and the Depositor
      shall
      have received the information described in the following sentence.  As
      a condition to the effectiveness of any such resignation, at least 15 calendar
      days prior to the effective date of such resignation, the Servicer shall provide
      (x) written notice to the Depositor of any successor pursuant to this Section
      and (y) in writing and in form and substance reasonably satisfactory to the
      Depositor, all information reasonably requested by the Depositor in order to
      comply with its reporting obligation under Item 6.02 of Form 8-K with respect
      to
      the resignation of the Servicer.

    Section
      7.01  Events
      of Default.

     

    “Event
      of Default,” wherever used in this Agreement, means any one of the
      following events:

     

    (a)  any
      failure by the Servicer to deposit in the Certificate Account or remit to the
      Trustee any payment required to be made by it under this Agreement, which
      failure continues unremedied for five days after the date on which written
      notice of the failure has been given to the Servicer by the Trustee or the
      Depositor or to the Servicer and the Trustee by the Holders of Certificates
      of
      any Class evidencing not less than 25% of the aggregate Percentage Interests
      of
      the Class; or

     

    (b)  any
      failure by the Servicer to observe or perform in any material respect any other
      of the covenants or agreements on the part of the Servicer contained in this
      Agreement (except with respect to a failure related to a Limited Exchange Act
      Reporting Obligation), which failure materially affects the rights of
      Certificateholders and continues unremedied for a period of 60 days after the
      date on which written notice of such failure shall have been given to the
      Servicer by the Trustee or the Depositor, or to the Servicer and the Trustee
      by
      the Holders of Certificates of any Class evidencing not less than 25% of the
      Percentage Interests of the Class; provided that the sixty-day cure period
      shall
      not apply to the initial delivery of the Mortgage File for Delay Delivery
      Mortgage Loans nor the failure to repurchase or substitute in lieu thereof;
      or

     

    (c)  a
      decree
      or order of a court or agency or supervisory authority having jurisdiction
      in
      the premises for the appointment of a receiver, conservator or liquidator in
      any
      insolvency, readjustment of debt, marshalling of assets and liabilities or
      similar proceedings, or for the winding-up or liquidation of its affairs, shall
      have been entered against the Servicer and such decree or order shall have
      remained in force undischarged or unstayed for a period of 60 consecutive days;
      or

     

    (d)  the
      Servicer shall consent to the appointment of a receiver, conservator or
      liquidator in any insolvency, readjustment of debt, marshalling of assets and
      liabilities or similar proceedings of or relating to the Servicer or all or
      substantially all of the property of the Servicer; or

     

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

     

    (f)  the
      Servicer shall fail (i) to make an Advance on the Servicer Advance Date or
      (ii)
      to reimburse in full the Trustee within two days of the Servicer Advance Date
      for any Advance made by the Trustee pursuant to Section 4.01(b).

     

    If
      an
      Event of Default described in clauses (a) through (f) of this Section 7.01
      occurs, then, and in each and every such case, so long as such Event of Default
      shall not have been remedied, the Trustee may, or at the direction of the
      Holders of Certificates of any Class evidencing not less than 66 2/3% of the
      Percentage Interests of the Class, the Trustee shall by notice in writing to
      the
      Servicer (with a copy to each Rating Agency), terminate all of the rights and
      obligations of the Servicer under this Agreement and in the Mortgage Loans
      and
      the proceeds thereof, other than its rights as a Certificateholder
      hereunder.  In addition, if during the period that the Depositor is
      required to file Exchange Act Reports with respect to the Trust Fund, the
      Servicer shall fail to observe or perform any of the obligations that constitute
      a Limited Exchange Act Reporting Obligation or the obligations set forth in
      Section 3.17(a) or Section 11.07(a)(i) and (ii), and such failure continues
      for
      the lesser of 10 calendar days or such period in which the applicable Exchange
      Act Report can be filed timely (without taking into account any extensions),
      so
      long as such failure shall not have been remedied, the Trustee shall, but only
      at the direction of the Depositor, terminate all of the rights and obligations
      of the Servicer under this Agreement and in and to the Mortgage Loans and the
      proceeds thereof, other than its rights as a Certificateholder
      hereunder.  The Depositor shall not be entitled to terminate the
      rights and obligations of the Servicer if a failure of the Servicer to identify
      a Subcontractor “participating in the servicing function” within the meaning of
      Item 1122 of Regulation AB was attributable solely to the role or functions
      of
      such Subcontractor with respect to mortgage loans other than the Mortgage
      Loans.

    On
      and
      after the receipt by the Servicer of such written notice, all authority and
      power of the Servicer hereunder, whether with respect to the Mortgage Loans
      or
      otherwise, shall pass to and be vested in the Trustee.  The Trustee
      shall make any Advance that the Servicer failed to make subject to Section
      3.05,
      whether or not the obligations of the Servicer have been terminated pursuant
      to
      this Section.  The Trustee is hereby authorized and empowered to
      execute and deliver, on behalf of the Servicer, as attorney-in-fact or
      otherwise, any documents and other instruments, and to do or accomplish all
      other acts or things necessary or appropriate to effect the purposes of such
      notice of termination, whether to complete the transfer and endorsement or
      assignment of the Mortgage Loans and related documents, or
      otherwise.  Unless expressly provided in such written notice, no such
      termination shall affect any obligation of the Servicer to pay amounts owed
      pursuant to Article VIII.  The Servicer agrees to cooperate with the
      Trustee in effecting the termination of the Servicer’s responsibilities and
      rights hereunder, including the transfer to the Trustee of all cash amounts
      which shall at the time be credited to the Certificate Account, or thereafter
      be
      received with respect to the Mortgage Loans.  If the Servicer fails to
      make any Advance required under Section 4.01 of this Agreement, thereby
      triggering an Event of Default described in clause (f) of this Section 7.01,
      the
      Trustee shall make such Advance on that Distribution Date.

     

    Notwithstanding
      any termination of the activities of the Servicer under this Agreement, the
      Servicer shall be entitled to receive, out of any late collection of a Scheduled
      Payment on a Mortgage Loan which was due before the notice terminating such
      Servicer’s rights and obligations as Servicer hereunder and received after such
      notice, that portion thereof to which such Servicer would have been entitled
      pursuant to Sections 3.09(a)(i) through (viii), and any other amounts payable
      to
      such Servicer hereunder the entitlement to which arose before the termination
      of
      its activities hereunder.

     

    If
      the
      Servicer is terminated, the Trustee shall provide the Depositor in writing
      and
      in form and substance reasonably satisfactory to the Depositor, all information
      reasonably requested by the Depositor in order to comply with its reporting
      obligation under Item 6.02 of Form 8-K with respect to a successor servicer
      in
      the event the Trustee should succeed to the duties of the Servicer as set forth
      herein.

     

    Section
      7.02  Trustee
      to Act; Appointment of Successor.

     

    On
      and
      after the time the Servicer receives a notice of termination pursuant to Section
      7.01, the Trustee shall, subject to and to the extent provided in Section 3.05,
      be the successor to the Servicer in its capacity as servicer under this
      Agreement and the transactions set forth or provided for herein and shall be
      subject to all the responsibilities, duties and liabilities relating thereto
      placed on the Servicer by the terms hereof and applicable law including the
      obligation to make Advances pursuant to Section 4.01.  As compensation
      therefor, the Trustee shall be entitled to all funds relating to the Mortgage
      Loans that the Servicer would have been entitled to charge to the Certificate
      Account or Distribution Account if the Servicer had continued to act hereunder,
      including, if the Servicer was receiving the Servicing Fee, the Servicing
      Fee.  Notwithstanding the foregoing, if the Trustee has become the
      successor to the Servicer in accordance with Section 7.01, the Trustee may,
      if
      it shall be unwilling to so act, or shall, if it is prohibited by applicable
      law
      from making Advances pursuant to Section 4.01 or if it is otherwise unable
      to so
      act, appoint, or petition a court of competent jurisdiction to appoint, any
      established mortgage loan servicing institution the appointment of which does
      not adversely affect the then current rating of the Certificates by each Rating
      Agency, as the successor to the Servicer hereunder in the assumption of all
      or
      any part of the responsibilities, duties or liabilities of the Servicer
      hereunder.  Any successor to the Servicer shall be an institution
      which is a FNMA and FHLMC approved seller/servicer in good standing, which
      has a
      net worth of at least $15,000,000, which is willing to service the Mortgage
      Loans and which executes and delivers to the Depositor and the Trustee an
      agreement accepting such delegation and assignment, containing an assumption
      by
      such Person of the rights, powers, duties, responsibilities, obligations and
      liabilities of the Servicer (other than liabilities of the Servicer under
      Section 6.03 incurred before termination of the Servicer under Section 7.01),
      with like effect as if originally named as a party to this Agreement; provided
      that each Rating Agency acknowledges that its rating of the Certificates in
      effect immediately before such assignment and delegation will not be qualified
      or reduced as a result of such assignment and delegation.  Pending
      appointment of a successor to the Servicer hereunder, the Trustee shall act
      in
      such capacity as provided above, subject to section 3.03 and unless prohibited
      by law.  In connection with such appointment and assumption, the
      Trustee may make such arrangements for the compensation of such successor out
      of
      payments on Mortgage Loans as it and such successor shall agree; provided,
      however, that in no case shall the rate of such compensation exceed the
      Servicing Fee Rate.  The Trustee and such successor shall take such
      action, consistent with this Agreement, as shall be necessary to effectuate
      any
      such succession.  Neither the Trustee nor any other successor servicer
      shall be deemed to be in default hereunder because of any failure to make,
      or
      any delay in making, any distribution hereunder or any portion thereof or any
      failure to perform, or any delay in performing, any duties or responsibilities
      hereunder, in either case caused by the failure of the Servicer to deliver
      or
      provide, or any delay in delivering or providing, any cash, information,
      documents or records to it.

      connection with the termination or resignation of the Servicer hereunder, either
      (i) the successor Servicer, including the Trustee if the Trustee is acting
      as
      successor Servicer, shall represent and warrant that it is a member of MERS
      in
      good standing and shall agree to comply in all material respects with the rules
      and procedures of MERS in connection with the servicing of the Mortgage Loans
      that are registered with MERS, or (ii) the predecessor Servicer shall cooperate
      with the successor Servicer either (x) in causing MERS to execute and deliver
      an
      assignment of Mortgage in recordable form to transfer the Mortgage from MERS
      to
      the Trustee and to execute and deliver such other notices, documents and other
      instruments as may be necessary or desirable to effect a transfer of such
      Mortgage Loan or servicing of such Mortgage Loan on the MERS® System to the
      successor Servicer or (y) in causing MERS to designate on the MERS® System the
      successor Servicer as the servicer of such Mortgage Loan.  The
      predecessor Servicer shall file or cause to be filed any such assignment in
      the
      appropriate recording office.  The successor Servicer shall cause such
      assignment to be delivered to the Trustee promptly upon receipt of the original
      with evidence of recording thereon or a copy certified by the public recording
      office in which such assignment was recorded.

     

    Any
      successor to the Servicer as servicer shall give notice to the Mortgagors of
      such change of servicer and shall, during the term of its service as servicer,
      maintain in force the policy or policies that the Servicer is required to
      maintain pursuant to this Agreement.

    ARTICLE
      EIGHT

     

    Concerning
      the Trustee

     

    Section
      8.01  Duties
      of the Trustee.

     

    The
      Trustee, before the occurrence of an Event of Default and after the curing
      of
      all Events of Default that may have occurred, shall undertake to perform such
      duties and only such duties as are specifically set forth in this
      Agreement.  In case an Event of Default has occurred and remains
      uncured, the Trustee shall exercise such of the rights and powers vested in
      it
      by this Agreement, and use the same degree of care and skill in their exercise
      as a prudent person would exercise or use under the circumstances in the conduct
      of such person’s own affairs.

     

    The
      Trustee, upon receipt of all resolutions, certificates, statements, opinions,
      reports, documents, orders or other instruments furnished to the Trustee that
      are specifically required to be furnished pursuant to any provision of this
      Agreement shall examine them to determine whether they are in the form required
      by this Agreement.  The Trustee shall not be responsible for the
      accuracy or content of any such resolution, certificate, statement, opinion,
      report, document, order, or other instrument.

     

    No
      provision of this Agreement shall be construed to relieve the Trustee from
      liability for its own negligent action, its own negligent failure to act or
      its
      own willful misconduct; provided, however, that, unless an Event of Default
      known to the Trustee has occurred and is continuing,

     

    (a)  the
      duties and obligations of the Trustee shall be determined solely by the express
      provisions of this Agreement, the Trustee shall not be liable except for the
      performance of the duties and obligations specifically set forth in this
      Agreement, no implied covenants or obligations shall be read into this Agreement
      against the Trustee, and the Trustee 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 and conforming to the
      requirements of this Agreement which it believed in good faith to be genuine
      and
      to have been duly executed by the proper authorities respecting any matters
      arising hereunder;

     

    (b)  the
      Trustee shall not be liable for an error of judgment made in good faith by
      a
      Responsible Officer or Responsible Officers of the Trustee, unless it is finally
      proven that the Trustee was negligent in ascertaining the pertinent facts;
      and

     

    (c)  the
      Trustee shall not be liable with respect to any action taken, suffered, or
      omitted to be taken by it in good faith in accordance with the direction of
      Holders of Certificates evidencing not less than 25% of the Voting Rights of
      Certificates relating to the time, method, and place of conducting any
      proceeding for any remedy available to the Trustee, or exercising any trust
      or
      power conferred upon the Trustee under this Agreement.  As long as any
      Voting Rights are held by parties other than the Seller, its Affiliates, or
      its
      agents, Voting Rights of Certificates held by the Seller, its Affiliates or
      its
      agents as the Seller shall certify to the Trustee upon any entity obtaining
      such
      ownership, will be excluded from participating in such voting arrangements,
      and
      excluded from determining the 25% threshold.

     

    Section
      8.02  Certain
      Matters Affecting the Trustee.

     

    Except
      as
      otherwise provided in Section 8.01:

     

    (a)  the
      Trustee may request and rely upon and shall be protected in acting or refraining
      from acting upon any resolution, Officer’s Certificate, certificate of auditors
      or any other certificate, statement, instrument, opinion, report, notice,
      request, consent, order, appraisal, bond or other paper or document believed
      by
      it to be genuine and to have been signed or presented by the proper party or
      parties and the Trustee shall have no responsibility to ascertain or confirm
      the
      genuineness of any signature of any such party or parties;

     

    
      
        
        

      

      
        86

        
          

        

      

      
        
        

      

    

     

    (b)  the
      Trustee may consult with counsel, financial advisers or accountants and the
      advice of any such counsel, financial advisers or accountants and 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 Opinion of Counsel;

     

    (c)  the
      Trustee shall not 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;

     

    (d)  the
      Trustee shall not be bound to make any investigation into the facts or matters
      stated in any resolution, certificate, statement, instrument, opinion, report,
      notice, request, consent, order, approval, bond or other paper or document,
      unless requested in writing so to do by Holders of Certificates evidencing
      not
      less than 25% of the Voting Rights allocated to each Class of Certificates;
      provided, however, that no Certificates held by the Seller, the Depositor or
      any
      Affiliate shall be given effect for the purpose of calculating any such
      aggregation of Voting Rights;

     

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

     

    (f)  the
      Trustee shall not be required to risk or expend its own funds or otherwise
      incur
      any financial liability in the performance of any of its duties or in the
      exercise of any of its rights or powers hereunder if it shall have reasonable
      grounds for believing that repayment of such funds or adequate indemnity against
      such risk or liability is not assured to it;

     

    (g)  the
      Trustee shall not be liable for any loss on any investment of funds pursuant
      to
      this Agreement (other than as issuer of the investment security);

     

    (h)  the
      Trustee shall not be deemed to have knowledge of an Event of Default until
      a
      Responsible Officer of the Trustee shall have received written notice
      thereof;

     

    (i)  the
      Trustee shall be under no obligation to exercise any of the trusts, rights
      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 this Agreement, unless such
      Certificateholders shall have offered to the Trustee reasonable security or
      indemnity satisfactory to the Trustee against the costs, expenses and
      liabilities which may be incurred therein or thereby;

     

    (j)  the
      Trustee or its Affiliates are permitted to receive additional compensation
      that
      could be deemed to be in the Trustee’s economic self-interest for (i) serving as
      investment adviser, administrator, shareholder servicing agent, custodian or
      sub-custodian with respect to certain of the Permitted Investments, (ii) using
      Affiliates to effect transactions in certain Permitted Investments and (iii)
      effecting transactions in certain Permitted Investments.  The Trustee
      does not guarantee the performance of any Permitted Investment; and

     

    
      
        
        

      

      
        87

        
          

        

      

      
        
        

      

    

     

    (k)  the
      Trustee shall not knowingly take any action that would cause the Trust Fund
      to
      fail to qualify as a qualifying special purpose entity.

     

    In
      order
      to comply with laws, rules, regulations and executive orders in effect from
      time
      to time applicable to banking institutions, including those relating to the
      funding of terrorist activities and money laundering ("Applicable Law"), the
      Trustee is required to obtain, verify and record certain information relating
      to
      individuals and entities which maintain a business relationship with the
      Trustee.  Accordingly, each of the parties agrees to provide to the
      Trustee upon its request from time to time such identifying
      information  and documentation as may be available for such party in
      order to enable the Trustee to comply with Applicable Law.

     

    Section
      8.03  Trustee
      Not Liable for Certificates or Mortgage Loans.

     

    The
      recitals contained herein and in the Certificates shall be taken as the
      statements of the Depositor or the Seller, as the case may be, and the Trustee
      assumes no responsibility for their correctness.  The Trustee makes no
      representations as to the validity or sufficiency of this Agreement or of the
      Certificates or of any Mortgage Loan or related document other than with respect
      to the Trustee’s execution and countersignature of the
      Certificates.  The Trustee shall not be accountable for the use or
      application by the Depositor or the Servicer of any funds paid to the Depositor
      or the Servicer in respect of the Mortgage Loans or deposited in or withdrawn
      from the Certificate Account by the Depositor or the Servicer.

     

    Except
      as
      provided in Section 2.01(c), the Trustee shall have no responsibility for filing
      or recording any financing or continuation statement in any public office at
      any
      time or to otherwise perfect or maintain the perfection of any security interest
      or lien granted to it hereunder (unless the Trustee shall have become the
      successor Servicer).  The Trustee makes no representations as to the
      validity or sufficiency of this Agreement or of the Certificates or of any
      Mortgage Loan or related document or of MERS or the MERS® System other than with
      respect to the Trustee’s execution and counter-signature of the
      Certificates.

     

    The
      Trustee executes the Certificates not in its individual capacity but solely
      as
      Trustee of the Trust Fund created by this Agreement, in the exercise of the
      powers and authority conferred and vested in it by this
      Agreement.  Each of the undertakings and agreements made on the part
      of the Trustee on behalf of the Trust Fund in the Certificates is made and
      intended not as a personal undertaking or agreement by the Trustee but is made
      and intended for the purpose of binding only the Trust Fund.

     

    Section
      8.04  Trustee
      May Own Certificates.

     

    The
      Trustee in its individual or any other capacity may become the owner or pledgee
      of Certificates with the same rights as it would have if it were not the
      Trustee.

     

    Section
      8.05  Trustee’s
      Fees and Expenses.

     

    As
      compensation for its activities under this Agreement, on each Distribution
      Date
      the Trustee may withdraw from the Distribution Account the Trustee Fee for
      that
      Distribution Date.  The Trustee and any director, officer, employee,
      or agent of the Trustee shall be indemnified by the Servicer against any loss,
      liability, or expense (including reasonable attorney’s fees) resulting from any
      error in any tax or information return prepared by the Servicer or incurred
      in
      connection with any claim or legal action relating to (a) this Agreement, (b)
      the Certificates, or (c) the performance of any of the Trustee’s duties under
      this Agreement, other than any loss, liability or expense incurred because
      of
      willful misfeasance, bad faith or negligence in the performance of any of the
      Trustee’s duties hereunder or incurred by reason of any action of the Trustee
      taken at the direction of the Certificateholders under this
      Agreement.  This indemnity shall survive the termination of this
      Agreement or the resignation or removal of the Trustee under this
      Agreement.  Without limiting the foregoing, except as otherwise agreed
      upon in writing by the Depositor and the Trustee, and except for any expense,
      disbursement, or advance arising from the Trustee’s negligence, bad faith, or
      willful misconduct, the Servicer shall pay or reimburse the Trustee, for all
      reasonable expenses, disbursements, and advances incurred or made by the Trustee
      in accordance with this Agreement with respect to

     

    
      
        
        

      

      
        88

        
          

        

      

      
        
        

      

    

     

    (A)  the
      reasonable compensation, expenses, and disbursements of its counsel not
      associated with the closing of the issuance of the Certificates,
      and

     

    (B)  the
      reasonable compensation, expenses, and disbursements of any accountant,
      engineer, or appraiser that is not regularly employed by the Trustee, to the
      extent that the Trustee must engage them to perform services under this
      Agreement.

     

    Except
      as
      otherwise provided in this Agreement, the Trustee shall not be entitled to
      payment or reimbursement for any routine ongoing expenses incurred by the
      Trustee in the ordinary course of its duties as Trustee, Registrar, or Paying
      Agent under this Agreement or for any other expenses.

     

    Section
      8.06  Eligibility
      Requirements for the Trustee.

     

    The
      Trustee hereunder shall at all times be a corporation or association organized
      and doing business under the laws of a state or the United States of America,
      authorized under such laws to exercise corporate trust powers, having a combined
      capital and surplus of at least $50,000,000, subject to supervision or
      examination by federal or state authority and with a credit rating which would
      not cause either of the Rating Agencies to reduce their respective then current
      ratings of the Certificates (or having provided such security from time to
      time
      as is sufficient to avoid such reduction) as evidenced in writing by each Rating
      Agency.  If such corporation or association publishes reports of
      condition at least annually, pursuant to law or to the requirements of the
      aforesaid supervising or examining authority, then for the purposes of this
      Section 8.06 the combined capital and surplus of such corporation or association
      shall be deemed to be its combined capital and surplus as set forth in its
      most
      recent report of condition so published.  In case at any time the
      Trustee shall cease to be eligible in accordance with this Section 8.06, the
      Trustee shall resign immediately in the manner and with the effect specified
      in
      Section 8.07.  The entity serving as Trustee may have normal banking
      and trust relationships with the Depositor and its affiliates or the Servicer
      and its affiliates; provided, however, that such entity cannot be an affiliate
      of the Seller, the Depositor or the Servicer other than the Trustee in its
      role
      as successor to the Servicer.

     

    Section
      8.07  Resignation
      and Removal of the Trustee.

     

    The
      Trustee may at any time resign and be discharged from the trusts hereby created
      by giving written notice of resignation to the Depositor, the Servicer, and
      each
      Rating Agency not less than 60 days before the date specified in such notice,
      when, subject to Section 8.08, such resignation is to take effect, and
      acceptance by a successor trustee in accordance with Section 8.08 meeting the
      qualifications set forth in Section 8.06.  If no successor trustee
      meeting such qualifications shall have been so appointed and have accepted
      appointment within 30 days after the giving of such notice or resignation,
      the
      resigning Trustee may petition any court of competent jurisdiction for the
      appointment of a successor trustee.

     

    As
      a
      condition to the effectiveness of any such resignation, at least 15 calendar
      days prior to the effective date of such resignation, the Trustee shall provide
      (x) written notice to the Depositor of any successor pursuant to this Section
      and (y) in writing and in form and substance reasonably satisfactory to the
      Depositor, all information reasonably requested by the Depositor in order to
      comply with its reporting obligation under Item 6.02 of Form 8-K with respect
      to
      the resignation of the Trustee.

     

    
      
        
        

      

      
        89

        
          

        

      

      
        
        

      

    

     

    If
      at any
      time (i) the Trustee shall cease to be eligible in accordance with Section
      8.06
      and shall fail to resign after written request thereto by the Depositor, (ii)
      the Trustee shall become incapable of acting, or shall be adjudged as bankrupt
      or insolvent, or a receiver of the Trustee or of its property shall be
      appointed, or any public officer shall take charge or control of the Trustee
      or
      of its property or affairs for the purpose of rehabilitation, conservation
      or
      liquidation, (iii)(A) a tax is imposed with respect to the Trust Fund by any
      state in which the Trustee or the Trust Fund is located and (B) the imposition
      of such tax would be avoided by the appointment of a different trustee, or
      (iv)
      during the period which the Depositor is required to file Exchange Act Reports
      with respect to the Trust Fund, the Trustee fails to comply with its obligations
      under the last sentence of Section 7.01, the preceding paragraph, Section 8.09
      or Article 11 and such failure is not remedied within the lesser of 10 calendar
      days or such period in which the applicable Exchange Act Report can be filed
      timely (without taking into account any extensions), then, in the case of
      clauses (i) through (iii), then the Depositor or the Servicer, or in the case
      of
      clause (iv), the Depositor, may remove the Trustee and appoint a successor
      trustee by written instrument, in triplicate, one copy of which shall be
      delivered to the Trustee, one copy to the Servicer and one copy to the successor
      trustee.

     

    The
      Holders of Certificates entitled to at least 51% of the Voting Rights may at
      any
      time remove the Trustee and appoint a successor trustee by written instrument
      or
      instruments, in triplicate, signed by such Holders or their attorneys-in-fact
      duly authorized, one complete set of which shall be delivered by the successor
      Trustee to the Servicer, one complete set to the Trustee so removed, one
      complete set to the successor so appointed and one complete set to the
      Depositor, together with a written description of the basis for such
      removal.  As long as any Voting Rights are held by parties other than
      the Seller, its Affiliates, or its agents, Voting Rights of Certificates held
      by
      the Seller, its Affiliates or its agents as the Seller shall certify to the
      Trustee upon any such entity obtaining such ownership will be excluded from
      participating in such voting arrangements, and excluded from determining the
      51%
      threshold.  The successor trustee shall notify each Rating Agency of
      any removal of the Trustee.

     

    Any
      resignation or removal of the Trustee and appointment of a successor trustee
      pursuant to this Section 8.07 shall become effective upon acceptance of
      appointment by the successor trustee as provided in Section 8.08.

     

    Section
      8.08  Successor
      Trustee.

     

    Any
      successor trustee appointed as provided in Section 8.07 shall execute,
      acknowledge and deliver to the Depositor and to its predecessor trustee and
      the
      Servicer an instrument accepting such appointment hereunder and thereupon the
      resignation or removal of the predecessor trustee shall become effective and
      such successor trustee, without any further act, deed or conveyance, shall
      become fully vested with all the rights, powers, duties and obligations of
      its
      predecessor hereunder, with the like effect as if originally named as trustee
      herein.  The Depositor, the Servicer and the predecessor trustee 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 all such rights, powers, duties, and obligations.

     

    No
      successor trustee shall accept appointment as provided in this Section 8.08
      unless, at the time of its acceptance, the successor trustee is eligible under
      Section 8.06 and its appointment does not adversely affect the then current
      rating of the Certificates and has provided to the Depositor in writing and
      in
      form and substance reasonably satisfactory to the Depositor, all information
      reasonably requested by the Depositor in order to comply with its reporting
      obligation under Item 6.02 of Form 8-K with respect to a replacement
      Trustee.

    Upon
      acceptance of appointment by a successor trustee as provided in this Section
      8.08, the Depositor shall mail notice of the succession of such trustee
      hereunder to all Holders of Certificates.  If the Depositor fails to
      mail such notice within 10 days after acceptance of appointment by the successor
      trustee, the successor trustee shall cause such notice to be mailed at the
      expense of the Depositor.

      8.09  Merger
      or Consolidation of the Trustee.

     

    Any
      corporation into which the Trustee may be merged or converted or with which
      it
      may be consolidated or any corporation resulting from any merger, conversion
      or
      consolidation to which the Trustee shall be a party, or any corporation
      succeeding to the business of the Trustee, shall be the successor of the Trustee
      hereunder, provided that such corporation shall be eligible under Section 8.06
      without the execution or filing of any paper or further act on the part of
      any
      of the parties hereto, anything herein to the contrary
      notwithstanding.

     

    As
      a
      condition to the effectiveness of any merger or consolidation, at least 15
      calendar days prior to the effective date of any merger or consolidation of
      the
      Trustee, the Trustee shall provide (x) written notice to the Depositor of any
      successor pursuant to this Section and (y) in writing and in form and substance
      reasonably satisfactory to the Depositor, all information reasonably requested
      by the Depositor in order to comply with its reporting obligation under Item
      6.02 of Form 8-K with respect to a replacement Trustee.

     

    Section
      8.10  Appointment
      of Co-Trustee or Separate Trustee.

     

    Notwithstanding
      any other provisions of this Agreement, at any time, for the purpose of meeting
      any legal requirements of any jurisdiction in which any part of the Trust Fund
      or property securing any Mortgage Note may at the time be located, the Servicer
      and the Trustee acting jointly 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 the Trust Fund, and to
      vest
      in such Person or Persons, in such capacity and for the benefit of the
      Certificateholders, such title to the Trust Fund or any part thereof, whichever
      is applicable, and, subject to the other provisions of this Section 8.10, such
      powers, duties, obligations, rights and trusts as the Servicer and the Trustee
      may consider appropriate.  If the Servicer shall not have joined in
      such appointment within 15 days after the receipt by it of a request to do
      so,
      or in the case an Event of Default shall have occurred and be continuing, the
      Trustee alone shall have the power to make such appointment.  No
      co-trustee or separate trustee hereunder shall be required to meet the terms
      of
      eligibility as a successor trustee under Section 8.06 and no notice to
      Certificateholders of the appointment of any co-trustee or separate trustee
      shall be required under Section 8.08.

     

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

     

    (a)  To
      the
      extent necessary to effectuate the purposes of this Section 8.10, all rights,
      powers, duties and obligations conferred or imposed upon the Trustee, except
      for
      the obligation of the Trustee under this Agreement to advance funds on behalf
      of
      the Servicer, shall be conferred or imposed upon and exercised or performed
      by
      the Trustee and such separate trustee or co-trustee jointly (it being understood
      that such separate trustee or co-trustee is not authorized to act separately
      without the Trustee joining in such act), except to the extent that under any
      law of any jurisdiction in which any particular act or acts are to be performed
      (whether as Trustee hereunder or as successor to the 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 the applicable Trust Fund or any portion thereof in any such
      jurisdiction) shall be exercised and performed singly by such separate trustee
      or co-trustee, but solely at the direction of the Trustee;

     

    
      
        
        

      

      
        91

        
          

        

      

      
        
        

      

    

     

    (b)  No
      trustee hereunder shall be held personally liable because of any act or omission
      of any other trustee hereunder and such appointment shall not, and shall not
      be
      deemed to, constitute any such separate trustee or co-trustee as agent of the
      Trustee;

     

    (c)  The
      Trustee may at any time accept the resignation of or remove any separate trustee
      or co-trustee; and

     

    (d)  The
      Servicer, and not the Trustee, shall be liable for the payment of reasonable
      compensation, reimbursement and indemnification to any such separate trustee
      or
      co-trustee.

     

    Any
      notice, request or other writing given to the Trustee shall be deemed to have
      been given to each of the separate trustees and co-trustees, when and 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 trusts conferred, shall be vested with
      the estates or property specified in its instrument of appointment, either
      jointly with the Trustee or separately, as may be provided therein, subject
      to
      all the provisions of this Agreement, specifically including every provision
      of
      this Agreement relating to the conduct of, affecting the liability of, or
      affording protection to, the Trustee.  Every such instrument shall be
      filed with the Trustee and a copy thereof given to the Servicer and the
      Depositor.

     

    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.

     

    Section
      8.11  Tax
      Matters.

     

    It
      is
      intended that the assets with respect to which one or more REMIC elections
      pertaining to the Trust Fund is to be made, as set forth in the Preliminary
      Statement, shall constitute, and that the conduct of matters relating to such
      assets shall be such as to qualify such assets as, a “real estate mortgage
      investment conduit” as defined in and in accordance with the REMIC
      Provisions.  In furtherance of such intention, the Trustee covenants
      and agrees that it shall act as agent (and the Trustee is hereby appointed
      to
      act as agent) on behalf of each REMIC created under this Agreement and that
      in
      such capacity it shall:

     

    (a)  prepare
      and file in a timely manner, a U.S. Real Estate Mortgage Investment Conduit
      Income Tax Return (Form 1066 or any successor form adopted by the Internal
      Revenue Service) with respect to each REMIC created hereunder and prepare and
      file with the Internal Revenue Service and applicable state or local tax
      authorities income tax or information returns for each taxable year with respect
      to each REMIC described in the Preliminary Statement, containing such
      information and at the times and in the manner as may be required by the Code
      or
      state or local tax laws, regulations, or rules, and furnish to
      Certificateholders the schedules, statements or information at such times and
      in
      such manner as may be required thereby;

     

    
      
        
        

      

      
        92

        
          

        

      

      
        
        

      

    

     

    (b)  within
      thirty days of the Closing Date, furnish to the Internal Revenue Service, on
      Forms 8811 or as otherwise may be required by the Code, the name, title,
      address, and telephone number of the person that the holders of the Certificates
      may contact for tax information relating thereto, together with such additional
      information as may be required by such Form, and update such information at
      the
      time or times in the manner required by the Code;

     

    (c)  make
      an
      election that each REMIC created under this Agreement be treated as a REMIC
      on
      the federal tax return for its first taxable year (and, if necessary, under
      applicable state law);

     

    (d)  prepare
      and forward to the Certificateholders and to the Internal Revenue Service and,
      if necessary, state tax authorities, all information returns and reports as
      and
      when required to be provided to them in accordance with the REMIC Provisions,
      including the calculations of any original issue discount and of taxable income
      or net loss to the holders of the residual interests in each REMIC created
      hereunder using the Prepayment Assumption (as defined in the Prospectus
      Supplement). For purposes of calculating taxable income or net loss to the
      holders of the residual interests in each such REMIC, the Trustee also shall
      assume that the indices in respect of any adjustable rate Mortgage Loans are
      static until the liquidation or purchase of the Mortgage Loans in accordance
      with Section 9.01;

     

    (e)  provide
      information necessary for the computation of tax imposed on the transfer of
      a
      Residual Certificate to a Person that is not a Permitted Transferee, or an
      agent
      (including a broker, nominee or other middleman) of a Person that is not a
      Permitted Transferee, or a pass-through entity in which a Person that is not
      a
      Permitted Transferee is the record holder of an interest (the reasonable cost
      of
      computing and furnishing such information may be charged to the Person liable
      for such tax);

     

    (f)  to
      the
      extent that they are under its control, conduct matters relating to such assets
      at all times that any Certificates are outstanding so as to maintain the status
      as any REMIC created under this Agreement under the REMIC
      Provisions;

     

    (g)  not
      knowingly or intentionally take any action or omit to take any action that
      would
      cause the termination of the REMIC status of any REMIC created under this
      Agreement;

     

    (h)  pay,
      from
      the sources specified in the third paragraph of this Section 8.11, the amount
      of
      any federal or state tax, including prohibited transaction taxes as described
      below, imposed on any REMIC before its termination when and as the same shall
      be
      due and payable (but such obligation shall not prevent the Trustee or any other
      appropriate Person from contesting any such tax in appropriate proceedings
      and
      shall not prevent the Trustee from withholding payment of such tax, if permitted
      by law, pending the outcome of such proceedings);

     

    (i)  ensure
      that federal, state or local income tax or information returns shall be signed
      by the Trustee or such other person as may be required to sign such returns
      by
      the Code or state or local laws, regulations or rules;

     

    (j)  maintain
      records relating to each REMIC created under this Agreement, including the
      income, expenses, assets, and liabilities thereof and the fair market value
      and
      adjusted basis of the assets determined at such intervals as may be required
      by
      the Code, as may be necessary to prepare the foregoing returns, schedules,
      statements or information; and

     

    (k)  as
      and
      when necessary and appropriate, represent each REMIC created under this
      Agreement in any administrative or judicial proceedings relating to an
      examination or audit by any governmental taxing authority, request an
      administrative adjustment as to any taxable year of such REMIC, enter into
      settlement agreements with any governmental taxing agency, extend any statute
      of
      limitations relating to any tax item of such REMIC, and otherwise act on behalf
      of such REMIC in relation to any tax matter or controversy involving
      it.

     

    
      
        
        

      

      
        93

        
          

        

      

      
        
        

      

    

     

    To
      enable
      the Trustee to perform its duties under this Agreement, the Depositor shall
      provide to the Trustee within ten days after the Closing Date all information
      or
      data that the Trustee requests in writing and determines to be relevant for
      tax
      purposes to the valuations and offering prices of the Certificates, including
      the price, yield, prepayment assumption, and projected cash flows of the
      Certificates and the Mortgage Loans.  Thereafter, the Depositor shall
      provide to the Trustee promptly upon written request therefor any additional
      information or data that the Trustee may, from time to time, reasonably request
      to enable the Trustee to perform its duties under this Agreement.  The
      Depositor hereby indemnifies the Trustee for any losses, liabilities, damages,
      claims, or expenses of the Trustee arising from any errors or miscalculations
      of
      the Trustee that result from any failure of the Depositor to provide, or to
      cause to be provided, accurate information or data to the Trustee on a timely
      basis.

     

    If
      any
      tax is imposed on “prohibited transactions” (as defined in section 860F(a)(2) of
      the Code) of any REMIC created under this Agreement, on the “net income from
      foreclosure property” of any REMIC created under this Agreement as defined in
      section 860G(c) of the Code, on any contribution to any REMIC created under
      this
      Agreement after the Startup Day pursuant to section 860G(d) of the Code, or
      any
      other tax is imposed, including any minimum tax imposed on any REMIC created
      hereunder pursuant to sections 23153 and 24874 of the California Revenue and
      Taxation Code, if not paid as otherwise provided for herein, the tax shall
      be
      paid by (i) the Trustee, if any such other tax arises out of or results from
      negligence of the Trustee in the performance of any of its obligations under
      this Agreement, (ii) the Servicer or the Seller, in the case of any such minimum
      tax, if such tax arises out of or results from a breach by the Servicer or
      Seller of any of their obligations under this Agreement, (iii) the Seller,
      if
      any such tax arises out of or results from the Seller’s obligation to repurchase
      a Mortgage Loan pursuant to Section 2.02 or 2.03, or (iv) in all other cases,
      or
      if the Trustee, the Servicer, or the Seller fails to honor its obligations
      under
      the preceding clauses (i), (ii), or (iii), any such tax will be paid with
      amounts otherwise to be distributed to the Certificateholders, as provided
      in
      Section 3.09(b).

     

    The
      Trustee shall file or cause to be filed with the Internal Revenue Service,
      Form
      1041 or such other form as may be applicable, and shall furnish or cause to
      be
      furnished to the Holders of the Class L Certificate the Late Payment Fees that
      are received, in the time or times and in the manner required by the
      Code.

     

    The
      Grantor Trust with respect to the Late Payment Fees
      shall terminate automatically upon termination of the Trust Fund.

    Termination

     

    Section
      9.01  Termination
      upon Liquidation or Purchase of the Mortgage Loans.

     

    Subject
      to Section 9.03, the obligations and responsibilities of the Depositor, the
      Servicer, and the Trustee created hereby shall terminate upon the earlier
      of

     

    (a)  the
      purchase by the Servicer of all Mortgage Loans (and REO Properties) at the
      price
      equal to the sum of

     

    (i)  100%
      of
      the Stated Principal Balance of each Mortgage Loan (other than in respect of
      a
      Delinquent Mortgage Loan or REO Property) plus one month’s accrued interest
      thereon at the applicable Adjusted Mortgage Rate less any amounts collected
      by
      the Servicer representing principal and interest due after the related Due
      Date,

     

    (ii)  the
      lesser of (x) the appraised value of any Delinquent Mortgage Loan or REO
      Property as determined by the higher of two appraisals completed by two
      independent appraisers selected by the Servicer at the expense of the Servicer
      and (y) the Stated Principal Balance of each such Delinquent Mortgage Loan
      or
      Mortgage Loan related to such REO Property, in each case plus accrued and unpaid
      interest thereon at the applicable Adjusted Net Mortgage Rate and

     

    (iii)  any
      costs
      and damages incurred by the Trust Fund in connection with any violation by
      each
      Mortgage Loan of any predatory or abusive lending law and

     

    (b)  the
      later
      of

     

    (i)  the
      maturity or other liquidation (or any Advance with respect thereto) of the
      last
      Mortgage Loan and the disposition of all REO Property and

     

    (ii)  the
      distribution to Certificateholders of all amounts required to be distributed
      to
      them pursuant to this Agreement.  In no event shall the trusts created
      hereby continue beyond the expiration of 21 years from the death of the survivor
      of the descendants of Joseph P.  Kennedy, the late Ambassador of the
      United States to the Court of St. James’s, living on the date of this
      Agreement.

     

    The
      right
      to purchase all Mortgage Loans and REO Properties pursuant to clause (a) above
      shall be conditioned upon the aggregate Stated Principal Balance of those
      Mortgage Loans, at the time of any such repurchase, aggregating less than ten
      percent (10%) of the aggregate Stated Principal Balance of the Mortgage Loans
      as
      of the Cut-off Date.  The first Distribution Date on which the right
      to purchase all Mortgage Loans and REO Properties pursuant to clause (a) above
      first becomes exercisable is referred to as the “Optional
      Termination Date.”  The Servicer shall effect any such
      repurchase by depositing the purchase price, as calculated above, as of the
      month preceding the date on which such purchase price shall be distributed
      to
      Certificateholders into the Certificate Account.  With such
      repurchase, the Servicer shall acquire any rights or potential rights of the
      Certificateholders or the Trustee to causes of action against any Person
      relating to the Mortgage Loans or the origination of the Mortgage Loans,
      including, without limitation, the right to enforce any breach of a
      representation or warranty made at any time with respect to the Mortgage
      Loans.

     

    The
      Grantor Trust with respect to the Late Payment Fees
      shall terminate automatically upon termination of the Trust Fund.

    Section
      9.02  Final
      Distribution on the Certificates.

     

    If
      on any
      Determination Date the Servicer determines that there are no Outstanding
      Mortgage Loans and no other funds or assets in the Trust Fund other than the
      funds in the Certificate Account, the Servicer shall direct the Trustee promptly
      to send a final distribution notice to each Certificateholder.  If the
      Servicer elects to terminate the Trust Fund pursuant to clause (a) of Section
      9.01, no later than the 15th day of
      the month
      preceding the month of the final Distribution Date the Servicer shall notify
      the
      Depositor and the Trustee of the date the Servicer intends to terminate the
      Trust Fund and of the applicable repurchase price of the Mortgage Loans and
      REO
      Properties.

     

    Notice
      of
      any termination of the Trust Fund specifying the Distribution Date on which
      Certificateholders may surrender their Certificates for payment of the final
      distribution and cancellation shall be given promptly by the Trustee by letter
      to Certificateholders mailed not earlier than the 15th day and not later than
      the last day of the month next preceding the month of such final
      distribution.  Any such notice shall specify (a) the Distribution Date
      upon which final distribution on the Certificates will be made upon presentation
      and surrender of Certificates at the office therein designated, (b) the amount
      of such final distribution, (c) the location of the office or agency at which
      such presentation and surrender must be made, and (d) that the Record Date
      otherwise applicable to the Distribution Date is not applicable, distributions
      being made only upon presentation and surrender of the Certificates at the
      office therein specified.  The Servicer will give such notice to each
      Rating Agency at the time such notice is given to
      Certificateholders.

     

    If
      this
      notice is given, the Servicer shall cause all funds in the Certificate Account
      to be remitted to the Trustee for deposit in the Distribution Account on the
      Business Day before the applicable Distribution Date in an amount equal to
      the
      final distribution in respect of the Certificates.  Upon such final
      deposit with respect to the Trust Fund and the receipt by the Trustee of a
      Request for Release therefor, the Trustee shall promptly release to the Servicer
      the Mortgage Files for the Mortgage Loans.

     

    Upon
      presentation and surrender of the Certificates, the Trustee shall cause to
      be
      distributed to the Certificateholders of each Class, in each case on the final
      Distribution Date and in the order set forth in Section 4.02, in proportion
      to their respective Percentage Interests, with respect to Certificateholders
      of
      the same Class, an amount equal to (i) as to each Class of Regular Certificates,
      its Certificate Balance plus for each such Class accrued interest thereon in
      the
      case of an interest-bearing Certificate and (ii) as to the Residual
      Certificates, any amount remaining on deposit in the Distribution Account (other
      than the amounts retained to meet claims) after application pursuant to clause
      (i) above.  Notwithstanding the reduction of the Certificate Balance
      of any Class of Certificates to zero, such Class will be outstanding hereunder
      solely for the purpose of receiving distributions and for no other purpose
      until
      the termination of the respective obligations and responsibilities of the
      Depositor, the Servicer and the Trustee hereunder in accordance with Article
      Nine.  The foregoing provisions are intended to distribute to each
      Class of Regular Certificates any accrued and unpaid interest and principal
      to
      which they are entitled based on the Pass-Through Rates and actual Class
      Certificate Balances set forth in the Preliminary Statement upon liquidation
      of
      the Trust Fund.

     

    If
      any
      affected Certificateholder does not surrender its Certificates for cancellation
      within six months after the date specified in the above mentioned written
      notice, the Trustee shall give a second written notice to the remaining
      Certificateholders to surrender their Certificates for cancellation and receive
      the final distribution with respect thereto.  If within six months
      after the second notice all the applicable Certificates shall not have been
      surrendered for cancellation, the Trustee may take appropriate steps, or may
      appoint an agent to take appropriate steps, to contact the remaining
      Certificateholders concerning surrender of their Certificates, and the cost
      thereof shall be paid out of the funds and other assets which remain a part
      of
      the Trust Fund.  If within one year after the second notice all
      Certificates shall not have been surrendered for cancellation, then the
      Class A-R Certificateholders shall be entitled to all unclaimed funds and
      other assets of the Trust Fund which remain subject hereto.

     

     

    Section
      9.03  Additional
      Termination Requirements.

     

    (a)  If
      the
      Servicer exercises its purchase option with respect to the Mortgage Loans as
      provided in Section 9.01, the Trust Fund shall be terminated in accordance
      with
      the following additional requirements, unless the Trustee has been supplied
      with
      an Opinion of Counsel, at the expense of the Servicer, to the effect that the
      failure to comply with the requirements of this Section 9.03 will not (i) result
      in the imposition of taxes on “prohibited transactions” on any REMIC created
      hereunder as defined in section 860F of the Code, or (ii) cause any REMIC
      created under this Agreement to fail to qualify as a REMIC at any time that
      any
      Certificates are outstanding:

     

    (b)  The
      Trustee shall sell all of the assets of the Trust Fund to the Servicer, and,
      within 90 days of such sale, shall distribute to the Certificateholders the
      proceeds of such sale in complete liquidation of each REMIC created under this
      Agreement.

     

    (c)  The
      Trustee shall attach a statement to the final federal income tax return for
      each
      REMIC created under this Agreement stating that pursuant to Treasury Regulation
      § 1.860F-1, the first day of the 90-day liquidation period for such REMIC was
      the date on which the Trustee sold the assets of the Trust Fund to the
      Servicer.

    Miscellaneous
      Provisions

     

    Section
      10.01  Amendment.

     

    This
      Agreement may be amended from time to time by the Depositor, the Servicer and
      the Trustee without the consent of any of the Certificateholders (i) to cure
      any
      ambiguity or mistake, (ii) to correct any defective provision in this Agreement
      or to supplement any provision in this Agreement which may be inconsistent
      with
      any other provision in this Agreement, (iii) to conform this Agreement to the
      Prospectus Supplement, (iv) to add to the duties of the Depositor, the Seller
      or
      the Servicer, (v) to modify, alter, amend, add to or rescind any of the terms
      or
      provisions contained in this Agreement to comply with any rules or regulations
      promulgated by the Commission from time to time, (vi) to add any other
      provisions with respect to matters or questions arising under this Agreement,
      or
      (vii) to modify, alter, amend, add to, or rescind any of the terms or provisions
      contained in this Agreement.

     

    No
      action
      pursuant to clauses (v), (vi) or (vii) above may, as evidenced by an Opinion
      of
      Counsel (which Opinion of Counsel shall not be an expense of the Trustee or
      the
      Trust Fund), adversely affect in any material respect the interests of any
      Certificateholder.  The amendment shall not be deemed to adversely
      affect in any material respect the interests of the Certificateholders if the
      Person requesting the amendment obtains a letter from each Rating Agency stating
      that the amendment would not result in the downgrading, qualification or
      withdrawal of the respective ratings then assigned to the
      Certificates.  Any such letter in and of itself will not represent a
      determination as to the materiality of any amendment and will represent a
      determination only as to the credit issues affecting any rating.  Each
      party to this Agreement agrees that it will cooperate with each other party
      in
      amending this Agreement pursuant to clause (v) above.

     

    The
      Trustee, the Depositor, and the Servicer also may at any time and from time
      to
      time amend this Agreement without the consent of the Certificateholders to
      modify, eliminate or add to any of its provisions to the extent necessary or
      helpful to (i) maintain the qualification of any REMIC created under this
      Agreement as a REMIC under the Code, (ii) avoid or minimize the risk of the
      imposition of any tax on any REMIC created under this Agreement pursuant to
      the
      Code that would be a claim at any time before the final redemption of the
      Certificates, or (iii) comply with any other requirements of the Code, if the
      Trustee has been provided an Opinion of Counsel, which opinion shall be an
      expense of the party requesting such opinion but in any case shall not be an
      expense of the Trustee or the Trust Fund, to the effect that the action is
      necessary or helpful for one of the foregoing purposes.

     

    This
      Agreement may also be amended from time to time by the Depositor, the Servicer,
      and the Trustee with the consent of the Holders of Certificates evidencing
      Percentage Interests aggregating not less than 51% of each Class of Certificates
      adversely affected thereby for the purpose of adding any provisions to or
      changing in any manner or eliminating any of the provisions of this Agreement
      or
      of modifying in any manner the rights of the Holders of
      Certificates.  As long as any Voting Rights are held by parties other
      than the Seller, its Affiliates, or its agents, as the Seller shall certify
      to
      the Trustee upon any such entity obtaining such ownership, Voting Rights of
      Certificates held by the Seller, its Affiliates or its agents will be excluded
      from participating in such voting arrangements, and excluded from determining
      the 51% threshold.  No amendment shall

     

     (i)           reduce
      in any manner the amount of, or delay the timing of, payments required to be
      distributed on any Certificate without the consent of the Holder of such
      Certificate,

     

    
      
        
        

      

      
        97

        
          

        

      

      
        
        

      

    

     

    (ii)           amend,
      modify, add to, rescind, or alter in any respect Section 10.13, notwithstanding
      any contrary provision of this Agreement, without the consent of the Holders
      of
      Certificates evidencing Percentage Interests aggregating not less than 66 2/3%
      (provided, however, that no Certificates held by the Seller, the Depositor
      or
      any Affiliate thereby shall be given effect for the purpose of calculating
      any
      such aggregation of Percentage Interests), or

     

    (iii)           reduce
      the aforesaid percentages of Certificates the Holders of which are required
      to
      consent to any such amendment, without the consent of the Holders of all such
      Certificates then outstanding.

     

    Notwithstanding
      any contrary provision of this Agreement, the Trustee shall not consent to
      any
      amendment to this Agreement unless (i) it shall have first received an Opinion
      of Counsel, which opinion shall not be an expense of the Trustee or the Trust
      Fund, to the effect that such amendment will not cause the imposition of any
      tax
      on any REMIC created under this Agreement or the Certificateholders or cause
      any
      REMIC created hereunder to fail to qualify as a REMIC at any time that any
      Certificates are outstanding and (ii) because the Trust Fund is required to
      be a
      Qualifying Special Purpose Entity (as that term is defined in Statement of
      Financial Accounting Standards No. 140 (“SFAS 140”),
      in order for the Seller to continue to account for the transfer of the Mortgage
      Loans under this Agreement as a sale under SFAS 140, prior to the parties hereto
      entering into such an amendment, the Trustee shall receive an Officer’s
      Certificate, which shall not be an expense of the Trustee or the Trust Fund,
      to
      the effect that such amendment would not “significantly change” (within the
      meaning of SFAS 140) the permitted activities of the Trust Fund so as to cause
      the Trust Fund to fail to qualify as a Qualifying Special Purpose
      Entity.

     

    Promptly
      after the execution of any amendment to this Agreement requiring the consent
      of
      Certificateholders, the Trustee shall furnish written notification of the
      substance or a copy of such amendment to each Certificateholder and each Rating
      Agency.

     

    It
      shall
      not be necessary for the consent of Certificateholders under this Section 10.01
      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.

     

    Nothing
      in this Agreement shall require the Trustee to enter into an amendment without
      receiving an Opinion of Counsel (which Opinion shall not be an expense of the
      Trustee or the Trust Fund), satisfactory to the Trustee that (i) such amendment
      is permitted and is not prohibited by this Agreement and that all requirements
      for amending this Agreement have been complied with; and (ii) either (A) the
      amendment does not adversely affect in any material respect the interests of
      any
      Certificateholder or (B) the conclusion set forth in the preceding clause (A)
      is
      not required to be reached pursuant to this Section 10.01.

     

    Section
      10.02  Recordation
      of Agreement; Counterparts.

     

    This
      Agreement 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 Servicer at its expense, but only upon receipt of 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
      10.03  Governing
      Law.

     

    THIS
      AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE SUBSTANTIVE
      LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED
      IN THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES
      HERETO AND THE CERTIFICATEHOLDERS SHALL BE DETERMINED IN ACCORDANCE WITH SUCH
      LAWS.

     

    Section
      10.04  Intention
      of Parties.

     

    It
      is the
      express intent of the parties hereto that the conveyance (i) of the Mortgage
      Loans by the Seller to the Depositor and (ii) of the Trust Fund by the Depositor
      to the Trustee each be, and be construed as, an absolute sale
      thereof.  It is, further, not the intention of the parties that such
      conveyances be deemed a pledge thereof.  However, if, notwithstanding
      the intent of the parties, the assets are held to be the property of the Seller
      or Depositor, as the case may be, or if for any other reason this Agreement
      is
      held or deemed to create a security interest in either such assets, then (i)
      this Agreement shall be deemed to be a security agreement within the meaning
      of
      the UCC and (ii) the conveyances provided for in this Agreement shall be deemed
      to be an assignment and a grant (i) by the Seller to the Depositor or (ii)
      by
      the Depositor to the Trustee, for the benefit of the Certificateholders, of
      a
      security interest in all of the assets transferred, whether now owned or
      hereafter acquired.

     

    The
      Seller and the Depositor for the benefit of the Certificateholders 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
      Trust Fund, 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 the Agreement.  The Depositor shall arrange for
      filing any Uniform Commercial Code continuation statements in connection with
      any security interest granted or assigned to the Trustee for the benefit of
      the
      Certificateholders.

     

    Section
      10.05  Notices.

     

    (a)  The
      Trustee shall use its best efforts to promptly provide notice to each Rating
      Agency with respect to each of the following of which it has actual
      knowledge:

     

    1.  Any
      material change or amendment to this Agreement;

     

    2.  The
      occurrence of any Event of Default that has not been cured;

     

    3.  The
      resignation or termination of the Servicer or the Trustee and the appointment
      of
      any successor;

     

    4.  The
      repurchase or substitution of Mortgage Loans pursuant to Section 2.03;
      and

     

    5.  The
      final distribution to Certificateholders.

    In
      addition, the Trustee shall promptly furnish to each Rating Agency copies of
      the
      following:

     

    1.  Each

      annual independent public accountants’ servicing report described in Section
      11.07; and

      notice of a purchase of a Mortgage Loan pursuant to Section 2.02, 2.03 or
      3.11.

     

    (b)  All
      directions, demands and notices hereunder shall be in writing and shall be
      deemed to have been duly given when delivered to (a) in the case of the
      Depositor, IndyMac MBS, Inc., 155 North Lake Avenue, Pasadena, California 91101,

      Servicer, IndyMac Bank, F.S.B., 888 East Walnut Street, Pasadena, California
      91101-7211, Attention: Secondary Marketing, Transaction Management or such
      other
      address as may be hereafter furnished to the Depositor and the Trustee by the
      Servicer in writing; (c) in the case of the Trustee to the Corporate Trust
      Office, Deutsche Bank National Trust Company, 1761 East St. Andrew Place, Santa
      Ana, California 92705-4934, Attention:  Trust Administration IN07D4,
      Series 2007-AR4, or such other address as the Trustee may hereafter furnish
      to
      the Depositor or Servicer and (d) in the case of each of the Rating Agencies,
      the address specified therefor in the definition corresponding to the name
      of
      such Rating Agency.  Notices to Certificateholders shall be deemed
      given when mailed, first class postage prepaid, to their respective addresses
      appearing in the Certificate Register.

     

    Section
      10.06  Severability
      of Provisions.

     

    If
      any
      one or more of the covenants, agreements, provisions or terms of this Agreement
      shall be for any reason whatsoever held invalid, then such covenants,
      agreements, provisions or terms shall be deemed severable from the remaining
      covenants, agreements, provisions or terms of this Agreement and shall in no
      way
      affect the validity or enforceability of the other provisions of this Agreement
      or of the Certificates or the rights of the Holders thereof.

     

    Section
      10.07  Assignment

     

    Notwithstanding
      anything to the contrary contained in this Agreement, except as provided in
      Section 6.02, this Agreement may not be assigned by the Servicer without the
      prior written consent of the Trustee and Depositor.

     

    Section
      10.08  Limitation
      on Rights of Certificateholders.

     

    The
      death
      or incapacity of any Certificateholder shall not operate to terminate this
      Agreement or the trust created by this Agreement, nor entitle such
      Certificateholder’s legal representative or heirs to claim an accounting or to
      take any action or commence any proceeding in any court for a petition or
      winding up of the trust created hereby, or otherwise affect the rights,
      obligations and liabilities of the parties to this Agreement or any of
      them.

     

    No
      Certificateholder shall have any right to vote (except as provided in this
      Agreement) or in any manner otherwise control the operation and management
      of
      the Trust Fund, or the obligations of the parties to this Agreement, 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 party because of any action taken by the parties
      to
      this Agreement pursuant to any provision of this Agreement.

    No
      Certificateholder shall have any right by virtue or by availing itself of any
      provisions of this Agreement to institute any suit, action or proceeding in
      equity or at law upon or under or with respect to this Agreement, unless such
      Holder previously shall have given to the Trustee a written notice of an Event
      of Default and of the continuance thereof, as provided in this Agreement, and
      unless the Holders of Certificates evidencing not less than 25% of the Voting
      Rights evidenced by the Certificates shall also have made written request to
      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 itself
      or
      themselves of any provisions of this Agreement to affect, disturb or prejudice
      the rights of the Holders of any other of the 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
      common benefit of all Certificateholders.  For the protection and
      enforcement of this Section 10.08, each Certificateholder and the Trustee shall
      be entitled to any relief that can be given either at law or in equity. As
      long
      as any Voting Rights are held by parties other than the Seller, its Affiliates,
      or its agents, Voting Rights of Certificates held by the Seller, its Affiliates
      or its agents as the Seller shall certify to the Trustee upon any entity
      obtaining such ownership, will be excluded from participating in such voting
      arrangements, and excluded from determining the 25% threshold.

     

    Section
      10.09  Inspection
      and Audit Rights.

     

    The
      Servicer agrees that, on reasonable prior notice, it will permit any
      representative of the Depositor or the Trustee during the Servicer’s normal
      business hours, to examine all the books of account, records, reports and other
      papers of the Servicer relating to the Mortgage Loans, to make copies and
      extracts therefrom, to cause such books to be audited by independent certified
      public accountants selected by the Depositor or the Trustee and to discuss
      its
      affairs, finances and accounts relating to the Mortgage Loans with its officers,
      employees and independent public accountants (and by this provision the Servicer
      hereby authorizes said accountants to discuss with such representative such
      affairs, finances and accounts), all at such reasonable times and as often
      as
      may be reasonably requested.  Any out-of-pocket expense incident to
      the exercise by the Depositor or the Trustee of any right under this Section
      10.09 shall be borne by the party requesting such inspection; all other such
      expenses shall be borne by the Servicer.

     

    Section
      10.10  Certificates
      Nonassessable and Fully Paid.

     

    It
      is the
      intention of the Depositor that Certificateholders shall not be personally
      liable for obligations of the Trust Fund, that the interests in the Trust Fund
      represented by the Certificates shall be nonassessable for any reason
      whatsoever, and that the Certificates, upon due authentication thereof by the
      Trustee pursuant to this Agreement, are and shall be deemed fully
      paid.

     

    Section
      10.11  Official
      Record.

     

    The
      Seller agrees that this Agreement is and shall remain at all times before the
      time at which this Agreement terminates an official record of the Seller as
      referred to in Section 13(e) of the Federal Deposit Insurance Act.

    Section
      10.12  Protection
      of Assets.

     

    (a)  Except

      Obligations.

     

    The
      Servicer, the Trustee and the Seller shall reasonably cooperate with the
      Depositor in connection with the satisfaction of the Depositor’s reporting
      requirements under the Exchange Act with respect to the Trust
      Fund.  In addition to the information specified below, if so requested
      by the Depositor for the purpose of satisfying its reporting obligation under
      the Exchange Act, the Servicer, the Trustee and the Seller shall provide the
      Depositor with (a) such information which is available to such Person without
      unreasonable effort or expense and within such timeframe as may be reasonably
      requested by the Depositor to comply with the Depositor’s reporting obligations
      under the Exchange Act and (b) to the extent such Person is a party (and the
      Depositor is not a party) to any agreement or amendment required to be filed,
      copies of such agreement or amendment in EDGAR-compatible form.

     

    Section
      11.02  Form
      10-D Filings.

     

    (a)  In
      accordance with the Exchange Act, unless no reporting obligation under the
      Exchange Act exists at such time with respect to the Trust Fund, the Trustee
      shall prepare for filing and file within 15 days after each Distribution Date
      (subject to permitted extensions under the Exchange Act) with the Commission
      with respect to the Trust Fund, a Form 10-D with copies of the Monthly Report
      and, to the extent delivered to the Trustee, no later than five calendar days
      following the Distribution Date, such other information identified by the
      Depositor or the Servicer, in writing, to be filed with the Commission (such
      other information, the “Additional Designated
      Information”).  If the Depositor or Servicer directs
      that any Additional Designated Information is to be filed with any Form 10-D,
      the Depositor or Servicer, as the case may be, shall specify the Item on Form
      10-D to which such information is responsive and, with respect to any Exhibit
      to
      be filed on Form 10-D, the Exhibit number.  Any information to be
      filed on Form 10-D shall be delivered to the Trustee in EDGAR-compatible form
      or
      as otherwise agreed upon by the Trustee and the Depositor or the Servicer,
      as
      the case may be, at the Depositor’s expense, and any necessary conversion to
      EDGAR-compatible format will be at the Depositor’s expense.  At the
      reasonable request of, and in accordance with the reasonable directions of,
      the
      Depositor or the Servicer, subject to the two preceding sentences, the Trustee
      shall prepare for filing and file an amendment to any Form 10-D previously
      filed
      with the Commission with respect to the Trust Fund.  The Depositor
      shall sign the Form 10-D filed on behalf of the Trust Fund.

    The
      Trustee shall prepare each Form 10-D and, no later than five Business Days
      prior
      to the date on which such Form 10-D is required to be filed, deliver a copy
      of
      such Form 10-D to the Depositor for review.  No later than the
      Business Day following the receipt thereof, the Depositor shall notify the
      Trustee of any changes to be made to the Form 10-D.  The Trustee shall
      make any changes thereto requested by the Depositor and deliver the final Form
      10-D to the Depositor for signature no later than three Business Days prior
      to
      the date on which such Form 10-D must be filed by the Trustee in accordance
      with
      this Section 11.02.  The Depositor shall execute the final Form 10-D
      and deliver the same to the Trustee via electronic mail
      (DBSEC.Notifications@db.com) or facsimile no later than the Business Day
      following receipt of the same (which, unless not received within such time
      frame
      from the Trustee, shall be no later than two Business Days prior to the date
      on
      which the Form 10-D is required to be filed), with an original executed hard
      copy to follow by overnight courier.

     

    (b)  No
      later
      than each Distribution Date, any party responsible for providing Additional
      Designated Information shall notify the Depositor and the Trustee of any Form
      10-D Disclosure Item, together with a description of any such Form 10-D
      Disclosure Item in form and substance reasonably acceptable to the
      Depositor.  In addition to such information as the Servicer and the
      Trustee are obligated to provide pursuant to other provisions of this Agreement,
      if so requested by the Depositor, each of the Servicer and the Trustee shall
      provide such information which is available to the Servicer and the Trustee,
      as
      applicable, without unreasonable effort or expense regarding the performance
      or
      servicing of the Mortgage Loans (in the case of the Trustee, based on the
      information provided by the Servicer) as is reasonably required to facilitate
      preparation of distribution reports in accordance with Item 1121 of Regulation
      AB.  Such information shall be provided concurrently with the
      Remittance Reports in the case of the Servicer and the Monthly Statement in
      the
      case of the Trustee, commencing with the first such report due not less than
      five Business Days following such request.

     

    (c)  The
      Trustee shall not have any responsibility to file any items (other than those
      generated by it) that have not been received in a format suitable (or readily
      convertible into a format suitable) for electronic filing via the EDGAR system
      and shall not have any responsibility to convert any such items to such format
      (other than those items generated by it or that are readily convertible to
      such
      format).  The Trustee shall have no liability to the
      Certificateholders, the Trust Fund, the Servicer or the Depositor with respect
      to any failure to properly prepare or file any of Form 10-D to the extent that
      such failure is not the result of any negligence, bad faith or willful
      misconduct on its part.  The Trustee will not have any duty to verify
      the accuracy or sufficiency of any information to be included in any Form 10-D
      not provided by it.  The Trustee shall have no liability with respect
      to any failure to properly prepare and file such periodic reports resulting
      from
      or relating to the Trustee’s inability or failure to obtain any information not
      resulting from its own negligence or willful misconduct.

     

    Section
      11.03  Form
      8-K Filings.

     

    The
      Servicer shall prepare and file on behalf of the Trust Fund any Form 8-K
      required by the Exchange Act.  Each Form 8-K must be signed by the
      Servicer.  Any reporting party identified on Exhibit T shall promptly
      notify the Depositor and the Servicer (if the notifying party is not the
      Servicer), but in no event later than one (1) Business Day after its occurrence,
      of any Reportable Event of which it has actual knowledge.  Each Person
      shall be deemed to have actual knowledge of any such event to the extent that
      it
      relates to such Person or any action or failure to act by such
      Person.

    Section
      11.04  Form
      10-K Filings.

     

    Prior
      to
      (x) March 31, 2008 and (y) unless and until a Form 15 Suspension Notice shall
      have been filed, March 31st of each year thereafter (or, in either case, such
      earlier date as may be required by the Exchange Act), the Trustee shall, subject
      to the provisions of this Section 11.04, file a Form 10-K, with respect to
      the
      Trust Fund.  The Trustee shall prepare and file on behalf of the Trust
      Fund a Form 10-K, in form and substance as required by the Exchange

      Business Days prior to the date on which such Form 10-K is required to be filed,
      deliver a copy of such Form 10-K to the Depositor for review.  No

      shall
      make any changes thereto requested by the Depositor and deliver the final Form
      10-K to the Depositor for signature no later than three Business Days prior
      to

      the
      Trustee, shall be no later than two Business Days prior to the date on which
      the
      From 10-K is required to be filed), with an original executed hard copy to
      follow by overnight mail. Such Form 10-K shall include the Assessment of

      Certification”), which shall be signed by the senior officer of the Depositor in
      charge of securitization, and an accountant’s report described under Section
      11.07.  Each Form 10-K shall also include any Sarbanes-Oxley
      Certification required to be included therewith, as described in Section
      11.05.

     

    If
      the
      Item 1119 Parties listed on Exhibit T have changed since the Closing Date,
      no
      later than March 1 of each year, the Depositor shall provide each of the
      Servicer and the Trustee via electronic mail (DBSEC.Notifications@db.com) with
      an updated Exhibit T setting forth the Item 1119 Parties.

     

    As
      to
      each item of information required to be included in any Form 10-D, Form 8-K
      or
      Form 10-K, the Trustee's or Depositor’s obligation to include the information in
      the applicable report is subject to receipt from the entity that is indicated
      in
      Exhibit Q as the responsible party for providing that information, if other
      than
      the Trustee or the Depositor, as applicable, as and when required as described
      above.  Each of the Trustee, the Servicer and the Depositor, as
      applicable, hereby agree to notify and provide to the Trustee and the Depositor
      all information that is required to be included in any Form 10-D, Form 8-K
      or
      Form 10-K, with respect to which that entity is indicated in Exhibit Q as the
      responsible party for providing that information. In the case of information
      to
      be included in the From 10-D, such information shall be delivered to the Trustee
      (with a copy to the Depositor) no later than 5 calendar days following each

      event.  In the case of information to be included in the From 10-K,
      such information, other than the documentation provided pursuant to Sections
      3.17 and 11.07, shall be delivered to the Trustee no later than (x) March 1,
      2008 (with a 15-day cure period) and (y) unless and until a Form 15 Suspension
      Notice shall have been filed, March 1st of each year thereafter.  The
      Servicer shall be responsible for determining the pool concentration applicable
      to any subservicer or originator at any time, for purposes of disclosure as
      required by Items 1117 and 1119 of Regulation AB.  The Trustee shall
      provide electronic or paper copies of all Form 10-D, 8-K and 10-K filings free
      of charge to any Certificateholder upon request.

     

    The
      Trustee shall sign a certification (in the form attached hereto as Exhibit
      O-2)
      for the benefit of the Depositor and its officers, directors and
      Affiliates.  The Trustee's certification shall be delivered to the
      Depositor by no later than March 18th of each year (or if such day is not a
      Business Day, the immediately preceding Business Day) and the Depositor shall
      deliver the Depositor Certification to the Trustee for filing no later than
      March 20th of each year (or if such day is not a Business Day, the immediately

    The
      Trustee shall indemnify and hold harmless the Depositor and its 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 (i) a breach of the
      Trustee’s obligations under this Section 11.04 and Section 11.07 or (ii) any
      material misstatement or omission contained in any information provided by
      the
      Trustee including, without limitation, in the certification provided by the
      Trustee in the form of Exhibit O-2 or the assessment of compliance provided
      pursuant to Section 11.07.  If the indemnification provided for herein
      is unavailable or insufficient to hold harmless the Depositor, then the Trustee,
      in connection with (i) a breach of the Trustee’s obligations under this Section
      11.04 or Section 11.07 or (ii) any material misstatement or omission contained
      in any information provided by the Trustee including, without limitation, in
      the
      certification provided by the Trustee in the form of Exhibit O-2, or in the
      assessment of compliance or attestation report provided pursuant to Section
      11.07, agrees that it shall contribute to the amount paid or payable by the
      Depositor as a result of the losses, claims, damages or liabilities of the
      Depositor in such proportion as is appropriate to reflect the relative fault
      of
      the Depositor on the one hand and the Trustee on the other.  This
      indemnification shall survive the termination of this Agreement or the
      termination of any party to this Agreement.

     

    The
      Servicer shall indemnify and hold harmless the Depositor, the Trustee and their
      respective officers, directors and Affiliates from and against any actual
      losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
      fees and related costs, judgments and other costs and expenses that such Person
      may sustain based upon (i) a breach of the Servicer’s obligations under Sections
      3.17, 11.07 or 11.04 or (ii) any material misstatement or omission contained
      in
      any information provided by the Servicer including, without limitation, in
      the
      information  provided pursuant to Sections 3.17 and 11.07. This
      indemnification shall survive the termination of this Agreement or the
      termination of any party to this Agreement.

     

    The
      Depositor shall indemnify and hold harmless the Servicer, the Trustee and their
      respective officers, directors and Affiliates from and against any actual
      losses, damages, penalties, fines, forfeitures, reasonable and necessary legal
      fees and related costs, judgments and other costs and expenses that such Person
      may sustain based upon (i) a breach of the Depositor’s obligations under this
      Section 11.04 or (ii) any material misstatement or omission contained in any
      information provided by the Depositor.

     

    The
      Trustee will have no duty or liability to verify the accuracy or sufficiency
      of
      any information not prepared by it included in any Form 10-D, Form 10-K or
      Form
      8-K.  The Trustee shall have no liability with respect to any failure
      to properly prepare or file any Form 10-D or Form 10-K resulting from or
      relating to the Trustee's inability or failure to receive any information in
      a
      timely manner from the party responsible for delivery of such
      information.  The Trustee shall have no liability with respect to any
      failure to properly file any Form 10-D or 10-K resulting from or relating to
      the
      Depositor's failure to timely comply with the provisions of this
      section.  Nothing herein shall be construed to require the Trustee or
      any officer, director or Affiliate thereof to sign any Form 10-D, Form 10-K
      or
      Form 8-K. Copies of all reports filed by the Trustee under the Exchange Act
      shall be sent to the Depositor electronically or at the address set forth in
      Section 10.05.  Fees and expenses incurred by the Trustee in
      connection with this Section 11.04 shall not be reimbursable from the Trust
      Fund.

     

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

    To
      the
      extent that, following the Closing Date, the Depositor certifies that reports
      and certifications differing from those required under this Section 11.04 are
      necessary to comply with the reporting requirements under the Exchange Act,
      the
      parties hereto hereby agree that each will reasonably cooperate to amend the
      provisions of this Section 11.04 in order to comply with such amended reporting
      requirements and such amendment of this Section 11.04.  Any such
      amendment may result in the reduction of the reports executed by and filed
      on
      behalf of the Depositor under the Exchange Act.  Notwithstanding the
      foregoing, the Trustee shall not be obligated to enter into any amendment
      pursuant to this Section that adversely affects its obligations and immunities
      under this Agreement.

     

    Each
      of
      the parties acknowledges and agrees that the purpose of Sections 3.17, 11.07
      and
      this Section 11.04 of this Agreement is to facilitate compliance by the
      Depositor with the provisions of Regulation AB.  Therefore, each of
      the parties agree that (a) the obligations of the parties hereunder shall be
      interpreted in such a manner as to accomplish that purpose, (b) the parties’
obligations hereunder will be supplemented and modified as necessary to be
      consistent with any such amendments, interpretive advice or guidance in respect
      of the requirements of Regulation AB, (c) the parties shall comply with
      reasonable requests made by the Depositor for delivery of additional or
      different information as the Depositor may determine in good faith is necessary
      to comply with the provisions of Regulation AB, and (d) no amendment of this
      Agreement shall be required to effect any such changes in the parties’
obligations as are necessary to accommodate evolving interpretations of the
      provisions of Regulation AB.

     

    Section
      11.05  Sarbanes-Oxley
      Certification.

     

    Each
      Form
      10-K shall include a certification (the “Sarbanes-Oxley
      Certification”) required by Rules 13a-14(d) and 15d-14(d) under
      the Exchange Act (pursuant to Section 302 of the Sarbanes-Oxley Act of 2002
      and
      the rules and regulations of the Commission promulgated thereunder (including
      any interpretations thereof by the Commission’s staff)).  No later
      than March 15 of each year, beginning in 2008, the Servicer and the Trustee
      shall (unless such person is the Certifying Person), and the Servicer shall
      cause each Reporting Subcontractor and the Trustee shall cause each Reporting
      Subcontractor to, provide to the Person who signs the Sarbanes-Oxley
      Certification (the “Certifying Person”) a
      certification (each, a “Performance Certification”),
      in the form attached hereto as Exhibit R on which the Certifying Person, the
      entity for which the Certifying Person acts as an officer, and such entity’s
      officers, directors and Affiliates (collectively with the Certifying Person,
      “Certification Parties”) can reasonably
      rely.  The senior officer in charge of the servicing function of the
      Servicer shall serve as the Certifying Person on behalf of the Trust
      Fund.  Neither the Servicer nor the Depositor will request delivery of
      a certification under this clause unless the Trustee is required under the
      Exchange Act to file an annual report on Form 10-K with respect to the Trust
      Fund.  In the event that prior to the filing date of the Form 10-K in
      March of each year, the Servicer or the Depositor has actual knowledge of
      information material to the Sarbanes-Oxley Certification, the Servicer or the
      Depositor, as the case may be, shall promptly notify the Servicer and the
      Trustee.  The respective parties hereto agree to cooperate with all
      reasonable requests made by any Certifying Person or Certification Party in
      connection with such Person’s attempt to conduct any due diligence that such
      Person reasonably believes to be appropriate in order to allow it to deliver
      any
      Sarbanes-Oxley Certification or portion thereof with respect to the Trust
      Fund.

      before March 15 of each calendar year, commencing in 2008, unless no reporting
      obligation under the Exchange Act exists at such time with respect to the Trust
      Fund:

     

    (i)  The
      Servicer shall deliver to the Trustee (with a copy to the Depositor) a report
      (in form and substance reasonably satisfactory to the Trustee) regarding the
      Servicer’s or the Trustee’s, as applicable, assessment of compliance with the
      Servicing Criteria during the immediately preceding calendar year, as required
      under Rules 13a-18 and 15d-18 of the Exchange Act and Item 1122 of Regulation
      AB.  Such report shall be signed by an authorized officer of such
      Person and shall address each of the Servicing Criteria applicable to each
      party
      specified on a certification delivered to the Trustee substantially in the
      form
      of Exhibit S.  To the extent any of the Servicing Criteria are not
      applicable to such Person, with respect to asset-backed securities transactions
      taken as a whole involving such Person and that are backed by the same asset
      type backing the Certificates, such report shall include such a statement to
      that effect.  The Trustee and the Servicer, and each of their
      respective officers and directors shall be entitled to rely upon each such
      servicing criteria assessment.

     

    (ii)  The
      Servicer shall deliver to the Trustee, and the Trustee shall provide on its
      own
      behalf, a report of a registered public accounting firm reasonably acceptable
      to
      the Trustee that attests to, and reports on, the assessment of compliance made
      by Servicer or the Trustee, as applicable, and delivered pursuant to the
      preceding paragraphs.  Such attestation shall be in accordance with
      Rules 1-02(a)(3) and 2-02(g) of Regulation S-X under the Securities Act and
      the
      Exchange Act, including, without limitation that in the event that an overall
      opinion cannot be expressed, such registered public accounting firm shall state
      in such report why it was unable to express such an opinion.  Such
      report must be available for general use and not contain restricted use
      language.  To the extent any of the Servicing Criteria are not
      applicable to such Person, with respect to asset-backed securities transactions
      taken as a whole involving such Person and that are backed by the same asset
      type backing the Certificates, such report shall include such a statement to
      that effect.

     

    (iii)  The
      Servicer shall cause each Reporting Subcontractor to deliver to the Trustee
      (with a copy to the Depositor) an assessment of compliance and accountant’s
      attestation as and when provided in paragraphs (a) and (b) of this Section
      11.07.

     

    (iv)  The
      Trustee shall cause each Reporting Subcontractor to deliver to the Trustee
      and
      the Servicer (with a copy to the Depositor) an assessment of compliance and
      accountant’s attestation as and when provided in paragraphs (a) and (b) of this
      Section.

     

    (v)  The
      Servicer shall execute (and the Servicer shall cause each Reporting
      Subcontractor to execute) a reliance certificate to enable the Certification
      Parties to rely upon each (A) annual compliance statement provided pursuant
      to
      Section 3.17, (B) annual report on assessments of compliance with servicing
      criteria provided pursuant to this Section 11.07 and (C) accountant’s report
      provided pursuant to this Section 11.07 and shall include a certification that
      each such annual compliance statement or report discloses any deficiencies
      or
      defaults described to the registered public accountants of such Person to enable
      such accountants to render the certificates provided for in this Section
      11.07.

     

    (vi)  The
      Trustee shall execute (and the Trustee shall cause each Reporting Subcontractor
      to execute) a reliance certificate to enable the Certification Parties to rely
      upon each (A) annual report on assessments of compliance with servicing criteria
      provided pursuant to this Section 11.07 and (C) accountant’s report provided
      pursuant to this Section 11.07 and shall include a certification that each
      such
      report discloses any deficiencies or defaults described to the registered public
      accountants of such Person to enable such accountants to render the certificates
      provided for in this Section 11.07.

    (b)  In
      the
      event the Servicer, the Trustee or Reporting Subcontractor is terminated or
      resigns during the term of this Agreement, such Person shall provide documents
      and information required by this Section 11.07 with respect to the period of
      time it was subject to this Agreement or provided services with respect to
      the
      Trust Fund, the Certificates or the Mortgage Loans.

     

    (c)  An
      assessment of compliance provided by a Subcontractor pursuant to Section
      11.07(a)(iii) or (iv) need not address any elements of the Servicing Criteria
      other than those specified by the Servicer or the Trustee, as applicable,
      pursuant to Section 11.07(a)(i).

     

    Section
      11.08  Use
      of Subcontractors.

     

    (a)  [Reserved].

     

    (b)  It
      shall
      not be necessary for the Servicer or the Trustee to seek the consent of the
      Depositor or any other party hereto to the utilization of any
      Subcontractor.  The Servicer or the Trustee, as applicable, shall
      promptly upon request provide to the Trustee and the Depositor (or any designee
      of the Depositor, such as the Servicer or administrator) a written description
      (in form and substance satisfactory to the Depositor) of the role and function
      of each Subcontractor utilized by such Person, specifying (i) the identity
      of
      each such Subcontractor, (ii) which (if any) of such Subcontractors are
“participating in the servicing function” within the meaning of Item 1122 of
      Regulation AB, and (iii) which elements of the Servicing Criteria will be
      addressed in assessments of compliance provided by each Subcontractor identified
      pursuant to clause (ii) of this paragraph.

     

    As
      a
      condition to the utilization of any Subcontractor determined to be a Reporting
      Subcontractor, the Servicer or the Trustee, as applicable, shall cause any
      such
      Subcontractor used by such Person for the benefit of the Depositor to comply
      with the provisions of Sections 11.07 and 11.09 of this Agreement to the same
      extent as if such Subcontractor were the Servicer  (except with
      respect to the Servicer’s duties with respect to preparing and filing any
      Exchange Act Reports or as the Certifying Person) or the Trustee, as
      applicable.  The Servicer or the Trustee, as applicable, shall be
      responsible for obtaining from each Subcontractor and delivering to the Trustee
      and the Servicer, any assessment of compliance and attestation required to
      be
      delivered by such Subcontractor under Section 11.05 and Section 11.07, in each
      case as and when required to be delivered.

     

    Section
      11.09  Amendments.

     

    In
      the
      event the parties to this Agreement desire to further clarify or amend any
      provision of this Article 11, this Agreement shall be amended to reflect the
      new
      agreement between the parties covering matters in this Article 11 pursuant
      to
      Section 10.01, which amendment shall not require any Opinion of Counsel or
      Rating Agency confirmations or the consent of any
      Certificateholder.

     

    If,
      during the period that the Depositor is required to file Exchange Act Reports
      with respect to the Trust Fund, the Servicer is no longer an Affiliate of the
      Depositor, the Depositor shall assume the obligations and responsibilities
      of
      the Servicer in this Article 11 with respect to the preparation and filing
      of
      the Exchange Act Reports and/or acting as the Certifying Person, if the
      Depositor has received indemnity from such successor Servicer satisfactory
      to
      the Depositor, and such Servicer has agreed to provide a Sarbanes-Oxley
      Certification to the Depositor substantially in the form of Exhibit
      U.

    IndyMac
      MBS, Inc. Mortgage Pass-Through Certificates, Series 2007-AR4

     

    Representations
      and Warranties of the Seller/Servicer

     

    Indy
      Mac
      Bank, F.S.B. (“IndyMac”) hereby makes the
      representations and warranties set forth in this Schedule II to the Depositor
      and the Trustee, as of the Closing Date.  Capitalized terms used but
      not otherwise defined in this Schedule II shall have the meanings assigned
      thereto in the Pooling and Servicing Agreement (the “Pooling and
      Servicing Agreement”) relating to the above-referenced Series,
      among IndyMac, as seller and servicer, IndyMac MBS, Inc., as depositor, and
      Deutsche Bank National Trust Company, as trustee.

     

    (1)
      IndyMac is duly organized as a federally insured savings bank and is validly
      existing and in good standing under the laws of the United States of America
      and
      is duly authorized and qualified to transact any business contemplated by the
      Pooling and Servicing Agreement to be conducted by IndyMac in any state in
      which
      a Mortgaged Property is located or is otherwise not required under applicable
      law to effect such qualification and, in any event, is in compliance with the
      doing business laws of any such state, to the extent necessary to ensure its
      ability to enforce each Mortgage Loan, to service the Mortgage Loans in
      accordance with the Pooling and Servicing Agreement and to perform any of its
      other obligations under the Pooling and Servicing Agreement in accordance with
      the terms thereof.

     

    (2)
      IndyMac has the full corporate power and authority to sell and service each
      Mortgage Loan, and to execute, deliver and perform, and to enter into and
      consummate the transactions contemplated by the Pooling and Servicing Agreement
      and has duly authorized by all necessary corporate action on the part of IndyMac
      the execution, delivery and performance of the Pooling and Servicing Agreement;
      and the Pooling and Servicing Agreement, assuming the due authorization,
      execution and delivery thereof by the other parties thereto, constitutes a
      legal, valid and binding obligation of IndyMac, enforceable against IndyMac
      in
      accordance with its terms, except that (a) the enforceability thereof may be
      limited by bankruptcy, insolvency, moratorium, receivership and other similar
      laws relating to creditors’ rights generally and (b) the remedy of specific
      performance and injunctive and other forms of equitable relief may be subject
      to
      equitable defenses and to the discretion of the court before which any
      proceeding therefor may be brought.

     

    (3)
      The
      execution and delivery of the Pooling and Servicing Agreement by IndyMac, the
      sale and servicing of the Mortgage Loans by IndyMac under the Pooling and
      Servicing Agreement, the consummation of any other of the transactions
      contemplated by the Pooling and Servicing Agreement, and the fulfillment of
      or
      compliance with the terms thereof are in the ordinary course of business of
      IndyMac and will not (A) result in a material breach of any term or provision
      of
      the charter or by-laws of IndyMac or (B) materially conflict with, result in
      a
      material breach, violation or acceleration of, or result in a material default
      under, any other material agreement or instrument to which IndyMac is a party
      or
      by which it may be bound, or (C) constitute a material violation of any statute,
      order or regulation applicable to IndyMac of any court, regulatory body,
      administrative agency or governmental body having jurisdiction over IndyMac
      (including the OTS, the Federal Deposit Insurance Corporation or any other
      governmental entity having regulatory authority over IndyMac); and IndyMac
      is
      not in breach or violation of any material indenture or other material agreement
      or instrument, or in violation of any statute, order or regulation of any court,
      regulatory body, administrative agency or governmental body having jurisdiction
      over it (including the OTS, the Federal Deposit Insurance Corporation or any
      other governmental entity having regulatory authority over IndyMac) which breach

    Representations
      and Warranties as to the Mortgage Loans

     

    IndyMac
      Bank, F.S.B. (“IndyMac”) hereby makes the
      representations and warranties set forth in this Schedule III to the Depositor
      and the Trustee, as of the Closing Date or if so specified in this Schedule
      III,
      as of the Cut-off Date with respect to each Mortgage
      Loan.  Capitalized terms used but not otherwise defined in this
      Schedule III shall have the meanings assigned to them in the Pooling and
      Servicing Agreement (the “Pooling and Servicing
      Agreement”) relating to the above-referenced Series, among
      IndyMac, as seller and servicer, IndyMac MBS, Inc., as depositor, and Deutsche
      Bank National Trust Company, as trustee.

     

    (1)
      The
      information set forth on Schedule I to the Pooling and Servicing Agreement
      with
      respect to each Mortgage Loan is true and correct in all material respects
      as of
      the Closing Date.

     

    (2)
      All
      regularly scheduled monthly payments due with respect to each Mortgage Loan
      up
      to and including the Due Date before the Cut-off Date have been made; and as
      of
      the Cut-off Date, no Mortgage Loan had a regularly scheduled monthly payment
      that was 60 or more days Delinquent during the twelve months before the Cut-off
      Date.

     

    (3)
      With
      respect to any Mortgage Loan that is not a Cooperative Loan, each Mortgage
      is a
      valid and enforceable first lien on the Mortgaged Property subject only to
      (a)
      the lien of nondelinquent current real property taxes and assessments and liens
      or interests arising under or as a result of any federal, state or local law,
      regulation or ordinance relating to hazardous wastes or hazardous substances
      and, if the related Mortgaged Property is a unit in a condominium project or
      planned unit development, any lien for common charges permitted by statute
      or
      homeowner association fees, (b) covenants, conditions and restrictions, rights
      of way, easements and other matters of public record as of the date of recording
      of such Mortgage, such exceptions appearing of record being generally acceptable
      to mortgage lending institutions in the area wherein the related Mortgaged
      Property is located or specifically reflected in the appraisal made in
      connection with the origination of the related Mortgage Loan, and (c) other
      matters to which like properties are commonly subject which do not materially
      interfere with the benefits of the security intended to be provided by such
      Mortgage.

     

    (4)
      Immediately before the assignment of the Mortgage Loans to the Depositor, the
      Seller had good title to, and was the sole owner of, each Mortgage Loan free
      and
      clear of any pledge, lien, encumbrance or security interest and had full right
      and authority, subject to no interest or participation of, or agreement with,
      any other party, to sell and assign the same pursuant to the Pooling and
      Servicing Agreement.

     

    (5)
      As of
      the Closing Date, there was no delinquent tax or assessment lien against the
      related Mortgaged Property.

     

    (6)
      There
      is no valid offset, defense or counterclaim to any Mortgage Note or Mortgage,
      including the obligation of the Mortgagor to pay the unpaid principal of or
      interest on such Mortgage Note.

     

    
      
        
        

      

      
        S-III-1

        
          

        

      

      
        
        

      

    

     

    (7)
      There
      are no mechanics’ liens or claims for work, labor or material affecting any
      Mortgaged Property which are or may be a lien prior to or equal with, the lien
      of such Mortgage, except those which are insured against by the title insurance
      policy referred to in item (11) below.

     

    (8)  No
      Mortgaged Property has been materially damaged by water, fire, earthquake,
      windstorm, flood, tornado or similar casualty (excluding casualty from the
      presence of hazardous wastes or hazardous substances, as to which the Seller
      makes no representation) so as to affect adversely the value of the related
      Mortgaged Property as security for the Mortgage Loan.

     

    (9)
      Each
      Mortgage Loan at origination complied in all material respects with applicable
      local, state and federal laws and regulations, including usury, equal credit
      opportunity, real estate settlement procedures, truth-in-lending, and disclosure
      laws, or any noncompliance does not have a material adverse effect on the value
      of the related Mortgage Loan.

     

    (10)
      The
      Seller has not modified the Mortgage in any material respect (except that a
      Mortgage Loan may have been modified by a written instrument which has been
      recorded or submitted for recordation, if necessary, to protect the interests
      of
      the Certificateholders and which has been delivered to the Trustee); satisfied,
      cancelled or subordinated such Mortgage in whole or in part; released the
      related Mortgaged Property in whole or in part from the lien of such Mortgage;
      or executed any instrument of release, cancellation, modification or
      satisfaction with respect thereto.

     

    (11)
      A
      lender’s policy of title insurance together with a condominium endorsement and
      extended coverage endorsement, if applicable, in an amount at least equal to
      the
      Cut-off Date Principal Balance of each such Mortgage Loan or a commitment
      (binder) to issue the same was effective on the date of the origination of
      each
      Mortgage Loan and each such policy is valid and remains in full force and
      effect.

     

    (12)
      Each
      Mortgage Loan was originated (within the meaning of Section 3(a)(41) of the
      Exchange Act) by an entity that satisfied at the time of origination the
      requirements of Section 3(a)(41) of the Exchange Act.

     

    (13)
      All
      of the improvements which were included for the purpose of determining the
      Appraised Value of the Mortgaged Property lie wholly within the boundaries
      and
      building restriction lines of such property, and no improvements on adjoining
      properties encroach upon the Mortgaged Property, unless such failure to be
      wholly within such boundaries and restriction lines or such encroachment, as
      the
      case may be, does not have a material effect on the value of the Mortgaged
      Property.

     

    (14)
      As
      of the date of origination of each Mortgage Loan, no improvement located on
      or
      being part of the Mortgaged Property is in violation of any applicable zoning
      law or regulation unless such violation would not have a material adverse effect
      on the value of the related Mortgaged Property.  All inspections,
      licenses and certificates required to be made or issued with respect to all
      occupied portions of the Mortgaged Property and, with respect to the use and
      occupancy of the same, including certificates of occupancy and fire underwriting
      certificates, have been made or obtained from the appropriate authorities,
      unless the lack thereof would not have a material adverse effect on the value
      of
      the Mortgaged Property.

     

    (15)
      The
      Mortgage Note and the related Mortgage are genuine, and each is the legal,
      valid
      and binding obligation of the maker thereof, enforceable in accordance with
      its
      terms and under applicable law.

     

    
      
        
        

      

      
        S-III-2

        
          

        

      

      
        
        

      

    

     

    (16)
      The
      proceeds of the Mortgage Loan have been fully disbursed and there is no
      requirement for future advances thereunder.

     

    (17)
      The
      related Mortgage contains customary and enforceable provisions which render
      the
      rights and remedies of the holder thereof adequate for the realization against
      the Mortgaged Property of the benefits of the security, including, (i) in the
      case of a Mortgage designated as a deed of trust, by trustee’s sale, and (ii)
      otherwise by judicial foreclosure.

     

    (18)
      With
      respect to each Mortgage constituting a deed of trust, a trustee, duly qualified
      under applicable law to serve as such, has been properly designated and
      currently so serves and is named in such Mortgage, and no fees or expenses
      are
      or will become payable by the Certificateholders to the trustee under the deed
      of trust, except in connection with a trustee’s sale after default by the
      Mortgagor.

     

    (19)
      At
      the Closing Date, the improvements upon each Mortgaged Property are covered
      by a
      valid and existing hazard insurance policy with a generally acceptable carrier
      that provides for fire and extended coverage and coverage for such other hazards
      as are customarily required by institutional single family mortgage lenders
      in
      the area where the Mortgaged Property is located, and the Seller has received
      no
      notice that any premiums due and payable thereon have not been paid; the
      Mortgage obligates the Mortgagor thereunder to maintain all such insurance
      including flood insurance at the Mortgagor’s cost and
      expense.  Anything to the contrary in this item (19) notwithstanding,
      no breach of this item (19) shall be deemed to give rise to any obligation
      of
      the Seller to repurchase or substitute for such affected Mortgage Loan or Loans
      so long as the Servicer maintains a blanket policy pursuant to the second
      paragraph of Section 3.10(a) of the Pooling and Servicing
      Agreement.

     

    (20)
      If
      at the time of origination of each Mortgage Loan, the related Mortgaged Property
      was in an area then identified in the Federal Register by the Federal Emergency
      Management Agency as having special flood hazards, a flood insurance policy
      in a
      form meeting the then-current requirements of the Flood Insurance Administration
      is in effect with respect to the Mortgaged Property with a generally acceptable
      carrier.

     

    (21)
      There is no proceeding pending or threatened for the total or partial
      condemnation of any Mortgaged Property, nor is such a proceeding currently
      occurring.

     

    (22)
      There is no material event which, with the passage of time or with notice and
      the expiration of any grace or cure period, would constitute a material
      non-monetary default, breach, violation or event of acceleration under the
      Mortgage or the related Mortgage Note; and the Seller has not waived any
      material non-monetary default, breach, violation or event of
      acceleration.

     

    (23)
      Each
      Mortgage File contains an appraisal prepared in accordance with the Uniform
      Standards of Professional Appraisal Practice (USPAP).

     

    (24)
      Any
      leasehold estate securing a Mortgage Loan has a stated term of not less than
      five years in excess of the term of the related Mortgage Loan.

     

    (25)
      Each
      Mortgage Loan was selected from among the outstanding adjustable rate one-
      to
      four-family mortgage loans in the Seller’s portfolio at the Closing Date as to
      which the representations and warranties made with respect to the Mortgage
      Loans
      set forth in this Schedule III can be made.  No such selection was
      made in a manner intended to adversely affect the interests of the
      Certificateholders.

     

    
      
        
        

      

      
        S-III-3

        
          

        

      

      
        
        

      

    

     

    (26)
      Approximately 0.30% of the Mortgage Loans as of the Cut-off Date are Cooperative
      Loans.

     

    (27)
      None
      of the Mortgage Loans is a “high cost” loan, “covered” loan or any other
      similarly designated loan as defined under any state, local or federal
      law,  as defined by applicable predatory and abusive lending
      laws.

     

    (28)
      No
      proceeds from any Mortgage Loan underlying the Certificates were used to finance
      single-premium credit insurance policies.

     

    (29)
      None
      of the Mortgage Notes related to the Mortgage Loans impose a Prepayment Charge
      on the related Mortgage Loan for a term in excess of five years from the
      origination of the Mortgage Loan.

     

    (30)
      Each
      Mortgage Loan was in compliance with the anti-predatory lending eligibility
      for
      purchase requirements of Fannie Mae’s Selling Guide.

     

    (31)
      Each
      Mortgage Loan has been underwritten and serviced substantially in accordance
      with the Seller’s guidelines, subject to such variances as are reflected on the
      Mortgage Loan Schedule or that the Seller has approved.

     

    (32)
      No
      Mortgage Loan is a High Cost Loan or Covered Loan, as applicable (as such terms
      are defined in the then-current version of Standard & Poor's LEVELS®
Glossary, which is now Version 6.0 Revised, Appendix E) and no Mortgage Loan
      originated on or after October 1, 2002 through March 6, 2003 is governed by
      the
      Georgia Fair Lending Act.

     

    (33)
      The
      Pooling and Servicing Agreement creates a valid and continuing “security
      interest” (as defined in Section 1-201(37) of the UCC) in each Mortgage Note in
      favor of the Trustee, which security interest is prior to all other liens and
      is
      enforceable as such against creditors of and purchasers from the Depositor.
      Each
      Mortgage Note constitutes “promissory notes” (as defined in Section 9-102(a)(65)
      of the UCC). Immediately before the assignment of each Mortgage Note to the
      Trustee, the Depositor had good and marketable title to such Mortgage Note
      free
      and clear of any lien, claim, encumbrance of any Person. All original executed
      copies of each Mortgage Note have been or shall be delivered to the Trustee
      within five Business Days following the Closing Date. Other than the security
      interest granted to the Trustee, the Depositor has not pledged, assigned, sold,
      granted a security interest in, or otherwise conveyed any Mortgage Note. The
      Depositor has not authorized the filing of and is not aware of any financing
      statements against the Depositor that include a description of any of the
      Mortgage Notes. The Depositor is not aware of any judgment or tax liens filed
      against the Depositor.  None of the Mortgage Notes has any marks or
      notations indicating that they have been pledged, assigned or otherwise conveyed
      to any Person other than the Trustee.

     

    (34)
      To
      the best of the Seller’s knowledge, there was no fraud involved in the
      origination of any Mortgage Loan by the mortgagee or by the Mortgagor, any
      appraiser or any other party involved in the origination of the Mortgage
      Loan.

     

    (35)  Each
      Mortgage Loan constitutes a “qualified mortgage” within the meaning of Section
      860G(a)(3) of the Code.

      Certificate belongs) in certain monthly distributions with respect to a Trust
      Fund consisting primarily of the Mortgage Loans deposited by IndyMac MBS, Inc.

    Principal
      in respect of this Certificate is distributable monthly as set forth herein

    [No
      transfer of a Certificate of this Class shall be made unless such transfer
      is
      made pursuant to an effective registration statement under the Securities Act
      and any applicable state securities laws or is exempt from the registration
      requirements under said Act and such laws.  In the event that a
      transfer is to be made in reliance upon an exemption from the Securities Act
      and
      such laws, in order to assure compliance with the Securities Act and such laws,
      the Certificateholder desiring to effect such transfer and such
      Certificateholder’s prospective transferee shall each certify to the Trustee in
      writing the facts surrounding the transfer.  In the event that such a
      transfer is to be made within three years from the date of the initial issuance
      of Certificates pursuant hereto, there shall also be delivered (except in the
      case of a transfer pursuant to Rule 144A of the Securities Act) to the Trustee
      an Opinion of Counsel that such transfer may be made pursuant to an exemption
      from the Securities Act and such state securities laws, which Opinion of Counsel
      shall not be obtained at the expense of the Trustee, the Seller, the Servicer
      or
      the Depositor.  The Holder hereof desiring to effect such transfer
      shall, and does hereby agree to, indemnify the Trustee and the Depositor 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.]

    IndyMac
      INDA Mortgage Loan Trust 200_-_

    Mortgage
      Pass-Through Certificates, Series 200_-_

     

    evidencing
      the distributions allocable to the Class A-R Certificates with respect to a
      Trust Fund consisting primarily of a pool of conventional mortgage loans (the
      “Mortgage Loans”) secured by first liens on one- to four-family residential
      properties.

     

    IndyMac
      MBS, Inc., as Depositor

     

    Principal
      in respect of this Certificate is distributable monthly as set forth herein
      or
      in the Agreement (defined below).  Accordingly, the Certificate
      Balance at any time may be less than the Certificate Balance as set forth
      herein.  This Certificate does not evidence an obligation of, or an
      interest in, and is not guaranteed by the Depositor, the Seller, the Servicer
      or
      the Trustee referred to below or any of their respective
      affiliates.  Neither this Certificate nor the Mortgage Loans are
      guaranteed or insured by any governmental agency or
      instrumentality.

     

    This
      certifies that
                                
      is the registered owner of the Percentage Interest (obtained by dividing the
      denomination of this Certificate by the aggregate Initial Certificate Balances
      of the denominations of all Certificates of the Class to which this Certificate
      belongs) in certain monthly distributions with respect to a Trust Fund
      consisting of the Mortgage Loans deposited by IndyMac MBS, Inc. (the
“Depositor”).  The Trust Fund was created pursuant to a Pooling and
      Servicing Agreement dated as of the Cut-off Date specified above (the
“Agreement”) among the Depositor, IndyMac Bank, F.S.B., as seller (in such
      capacity, the “Seller”) and as servicer (in such capacity, the “Servicer”), and
      Deutsche Bank National Trust Company, as trustee (the “Trustee”).  To
      the extent not defined herein, the capitalized terms used herein have the
      meanings assigned 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 the acceptance
      hereof assents and by which such Holder is bound.

     

    Any
      distribution of the proceeds of any remaining assets of the Trust Fund will
      be
      made only upon presentment and surrender of this Class A-R Certificate at the
      Corporate Trust Office.

     

    No
      transfer of a Class A-R Certificate shall be made unless the Trustee shall
      have
      received either (i) a representation letter from the transferee of such
      Certificate, acceptable to and in form and substance satisfactory to the
      Trustee, to the effect that such transferee is not an employee benefit plan
      subject to Section 406 of ERISA or Section 4975 of the Code, nor a person
      investing on behalf of or with plan assets of any such plan, which
      representation letter shall not be an expense of the Trustee or the Servicer,
      (ii) if the purchaser is an insurance company, a representation that the
      purchaser is an insurance company which is purchasing such Certificate with
      funds contained in an “insurance company general account” (as such term is
      defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE
      95-60”)) and that the purchase and holding of such Certificate are covered under
      Sections I and III of PTCE 95-60 or (iii) in the case of any such Certificate
      presented for registration in the name of an employee benefit plan subject
      to
      ERISA or Section 4975 of the Code (or comparable provisions of any subsequent
      enactments), or a trustee of any such plan or any other person acting on behalf
      of any such plan, an Opinion of Counsel satisfactory to the Trustee to the
      effect that the purchase or holding of such Class A-R Certificate will not
      result in a nonexempt prohibited transaction under Section 406 of ERISA or
      Section 4975 of the Code and will not subject the Trustee or the Servicer to
      any
      obligation in addition to those undertaken in the Agreement, which Opinion
      of
      Counsel shall not be an expense of the Trustee, the Servicer or the Trust
      Fund.  Notwithstanding anything else to the contrary herein, any
      purported transfer of a Class A-R Certificate to or on behalf of an employee
      benefit plan subject to ERISA or to Section 4975 of the Code without the opinion
      of counsel satisfactory to the Trustee as described above shall be void and
      of
      no effect.

    Each
      Holder of this Class A-R Certificate will be deemed to have agreed to be bound
      by the restrictions of the Agreement, including but not limited to the
      restrictions that (i) each person holding or acquiring any Ownership Interest
      in
      this Class A-R Certificate must be a Permitted Transferee, (ii) no Ownership
      Interest in this Class A-R Certificate may be transferred without delivery
      to
      the Trustee of (a) a transfer affidavit of the proposed transferee and (b)
      a
      transfer certificate of the transferor, each of such documents to be in the
      form
      described in the Agreement, (iii) each person holding or acquiring any Ownership
      Interest in this Class A-R Certificate must agree to require a transfer
      affidavit and to deliver a transfer certificate to the Trustee as required
      pursuant to the Agreement, (iv) each person holding or acquiring an Ownership
      Interest in this Class A-R Certificate must agree not to transfer an Ownership
      Interest in this Class A-R Certificate if it has actual knowledge that the
      proposed transferee is not a Permitted Transferee and (v) any attempted or
      purported transfer of any Ownership Interest in this Class A-R Certificate
      in
      violation of such restrictions will be absolutely null and void and will vest
      no
      rights in the purported transferee.

     

    Reference
      is hereby made to the further provisions of this Certificate set forth on the
      reverse hereof, which further provisions shall for all purposes have the same
      effect as if set forth at this place.

     

    This
      Certificate shall not be entitled to any benefit under the Agreement or be
      valid
      for any purpose unless manually countersigned by an authorized signatory of
      the
      Trustee.

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

    IndyMac
      INDA Mortgage Loan Trust 200_-_

    Mortgage
      Pass-Through Certificates, Series 200_-_

     

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      IndyMac MBS, Inc. Mortgage Pass-Through Certificates, of the Series specified
      on
      the face hereof (herein collectively called the “Certificates”), and
      representing a beneficial ownership interest in the Trust Fund created by the
      Agreement.

     

    The
      Certificateholder, by its acceptance of this Certificate, agrees that it will
      look solely to the funds on deposit in the Distribution Account for payment
      hereunder and that the Trustee is not liable to the Certificateholders for
      any
      amount payable under this Certificate or the Agreement or, except as expressly
      provided in the Agreement, subject to any liability under the
      Agreement.

     

    This
      Certificate does not purport to summarize the Agreement and reference is made
      to
      the Agreement for the interests, rights and limitations of rights, benefits,
      obligations and duties evidenced thereby, and the rights, duties and immunities
      of the Trustee.

     

    Pursuant
      to the terms of the Agreement, a distribution 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 (the “Distribution Date”), commencing on the first
      Distribution Date specified on the face hereof, to the Person in whose name
      this
      Certificate is registered at the close of business on the applicable 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 Holders of Certificates
      of the Class to which this Certificate belongs on such Distribution Date
      pursuant to the Agreement.  The Record Date applicable to each
      Distribution Date is the last Business Day of the month next preceding the
      month
      of such Distribution Date.

     

    Distributions
      on this Certificate shall be made by wire transfer of immediately available
      funds to the account of the Holder hereof at a bank or other entity having
      appropriate facilities therefor, if such Certificateholder shall have so
      notified the Trustee in writing at least five Business Days prior to the Record
      Date and such Certificateholder shall satisfy the conditions to receive such
      form of payment set forth in the Agreement, or, if not, by check mailed by
      first
      class mail to the address of such Certificateholder appearing in the Certificate
      Register.  The final distribution on each Certificate will be made in
      like manner, but only upon presentment and surrender of such Certificate at
      the
      Corporate Trust Office or such other location specified in the notice to
      Certificateholders of such final distribution.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Trustee and
      the rights of the Certificateholders under the Agreement at any time by the
      Depositor, the Servicer and the Trustee with the consent of the Holders of
      Certificates affected by such amendment evidencing the requisite Percentage
      Interest, as provided in the Agreement.  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 therefor 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.

     

    
      
        
        

      

      
        E-1

        
          

        

      

      
        
        

      

    

     

    As
      provided in the Agreement and subject to certain limitations therein set forth,
      the transfer of this Certificate is registrable in the Certificate Register
      of
      the Trustee upon surrender of this Certificate for registration of transfer
      at
      the Corporate Trust Office, accompanied by a written instrument of transfer
      in
      form satisfactory to the Trustee and the Certificate Registrar 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 and evidencing the same aggregate Percentage Interest in the
      Trust
      Fund will be issued to the designated transferee or transferees.

     

    The
      Certificates are issuable only as registered Certificates without coupons in
      denominations 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
      and 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,
      but the Trustee may require payment of a sum sufficient to cover any tax or
      other governmental charge payable in connection therewith.

     

    The
      Depositor, the Servicer, the Seller and the Trustee and any agent of the
      Depositor or the Trustee may treat the Person in whose name this Certificate
      is
      registered as the owner hereof for all purposes, and neither the Depositor,
      the
      Trustee, nor any such agent shall be affected by any notice to the
      contrary.

     

    On
      any
      Distribution Date on which the aggregate Stated Principal Balance of the
      Mortgage Loans in the mortgage pool is less than 10% of the Cut-off Date Pool
      Principal Balance, the Servicer will have the option to repurchase, in whole,
      from the Trust Fund all remaining Mortgage Loans in the mortgage pool and all
      property acquired in respect of the Mortgage Loans in the mortgage pool at
      a
      purchase price determined as provided in the Agreement.  In the event
      that no such optional termination occurs, the obligations and responsibilities
      created by the Agreement will terminate upon the later of the maturity or other
      liquidation (or any advance with respect thereto) of the last Mortgage Loan
      remaining in the Trust Fund or the disposition of all property in respect
      thereof and the distribution to Certificateholders of all amounts required
      to be
      distributed pursuant to the Agreement.  In no event, however, will the
      trust created by the Agreement continue beyond the expiration of 21 years from
      the death of the last survivor of the descendants living at the date of the
      Agreement of a certain person named in the Agreement.

     

    Any
      term
      used herein that is defined in the Agreement shall have the meaning assigned
      in
      the Agreement, and nothing herein shall be deemed inconsistent with that
      meaning.

    evidencing
      a percentage interest in the distributions allocable to the Certificates of
      the
      above-referenced Class with respect to a Trust Fund consisting primarily of
      a
      pool of conventional mortgage loans (the “Mortgage Loans”) secured by first
      liens on one- to four-family residential properties.

     

    Distributors
      in respect of this Certificate are distributable monthly as set forth
      herein.  Accordingly, the Certificate Balance at any time may be less
      than the Certificate Balance as set forth herein.  This Certificate
      does not evidence an obligation of, or an interest in, and is not guaranteed
      by
      the Depositor, the Seller, the Servicer or the Trustee referred to below or
      any
      of their respective affiliates.  Neither this Certificate nor the
      Mortgage Loans are guaranteed or insured by any governmental agency or
      instrumentality.

     

    This
      certifies that ________________ is the registered owner of the Percentage
      Interest evidenced by this Certificate (obtained by dividing the denomination
      of
      this Certificate by the aggregate of the denominations of all Certificates
      of
      the Class to which this Certificate belongs) in certain monthly distributions
      with respect to a Trust Fund consisting primarily of the Mortgage Loans
      deposited by IndyMac MBS, Inc. (the “Depositor”).  The Trust Fund was
      created pursuant to a Pooling and Servicing Agreement dated as of the Cut-off
      Date specified above (the “Agreement”) among the Depositor, IndyMac Bank,
      F.S.B., as seller and servicer (the "Seller" or the "Servicer", as
      appropriate),  and Deutsche Bank National Trust Company, as trustee
      (the “Trustee”).  To the extent not defined herein, the capitalized
      terms used herein have the meanings assigned 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 the acceptance hereof assents and by which such Holder is
      bound.

    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 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.

     

    This
      Certificate does not have a Certificate Balance or Pass-Through Rate and will
      be
      entitled to distributions only to the extent set forth in the
      Agreement.  In addition, any distribution of the proceeds of any
      remaining assets of the Trust will be made only upon presentment and surrender
      of this Certificate at the Corporate Trust Office or the office or agency
      maintained by the Trustee.

     

    No
      transfer of a Certificate of this Class shall be made unless such disposition
      is
      exempt from the registration requirements of the Securities Act of 1933, as
      amended (the “1933 Act”), and any applicable state securities laws or is made in
      accordance with the 1933 Act and such laws.  In the event of any such
      transfer, the Trustee shall require the transferor to execute a transferor
      certificate (in substantially the form attached to the Pooling and Servicing
      Agreement) and deliver either (i) an Investment Letter  or the Rule
      144A Letter, in either case substantially in the form attached to the Agreement,
      or (ii) a written Opinion of Counsel to the Trustee that such transfer may
      be
      made pursuant to an exemption, describing the applicable exemption and the
      basis
      therefor, from the 1933 Act or is being made pursuant to the 1933 Act, which
      Opinion of Counsel shall be an expense of the transferor.

     

    [No
      transfer of a Certificate of this Class shall be made unless the Trustee shall
      have received either (i) a representation [letter] from the transferee of such
      Certificate, acceptable to and in form and substance satisfactory to the
      Trustee, to the effect that such transferee is not an employee benefit plan
      or
      other benefit plan subject to Section 406 of ERISA or Section 4975 of the Code,
      or a person acting on behalf of or investing plan assets of any such plan,
      which
      representation letter shall not be an expense of the Trustee or the Servicer,
      (ii) if the purchaser is an insurance company and the Certificate has been
      the
      subject of an ERISA-Qualifying Underwriting, a representation that the purchaser
      is an insurance company which is purchasing such Certificates with funds
      contained in an “insurance company general account” (as such term is defined in
      Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and
      that the purchase and holding of such Certificates are covered under Sections
      I
      and III of PTCE 95-60 or (iii) in the case of any such Certificate presented
      for
      registration in the name of an employee benefit plan subject to ERISA or Section
      4975 of the Code (or comparable provisions of any subsequent enactments), or
      a
      trustee of any such plan or any other person acting on behalf of any such plan,
      an Opinion of Counsel satisfactory to the Trustee and the Servicer to the effect
      that the purchase or holding of such Certificate will not result in a nonexempt
      prohibited transaction under ERISA or Section 4975 of the Code and will not
      subject the Trustee or the Servicer to any obligation in addition to those
      undertaken in the Agreement, which Opinion of Counsel shall not be an expense
      of
      the Trustee, the Servicer or the Trust Fund.  Notwithstanding anything
      else to the contrary herein, any purported transfer of a Certificate of this
      Class to or on behalf of an employee benefit plan subject to ERISA or to Section
      4975 of the Code without the opinion of counsel satisfactory to the Trustee
      as
      described above shall be void and of no effect.]

     

    Reference
      is hereby made to the further provisions of this Certificate set forth on the
      reverse hereof, which further provisions shall for all purposes have the same
      effect as if set forth at this place.

     

    This
      Certificate shall not be entitled to any benefit under the Agreement or be
      valid
      for any purpose unless manually countersigned by an authorized signatory of
      the
      Trustee.

    This
      Certificate is one of a duly authorized issue of Certificates designated as
      IndyMac MBS, Inc. Mortgage Pass-Through Certificates, of the Series specified
      on
      the face hereof (herein collectively called the “Certificates”), and
      representing a beneficial ownership interest in the Trust Fund created by the
      Agreement.

     

    The
      Certificateholder, by its acceptance of this Certificate, agrees that it will
      look solely to the funds on deposit in the Distribution Account for payment
      hereunder and that the Trustee is not liable to the Certificateholders for
      any
      amount payable under this Certificate or the Agreement or, except as expressly
      provided in the Agreement, subject to any liability under the
      Agreement.

     

    This
      Certificate does not purport to summarize the Agreement and reference is made
      to
      the Agreement for the interests, rights and limitations of rights, benefits,
      obligations and duties evidenced thereby, and the rights, duties and immunities
      of the Trustee.

     

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

      immediately following (the “Distribution Date”), commencing on the first
      Distribution Date specified on the face hereof, to the Person in whose name
      this
      Certificate is registered at the close of business on the applicable 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 Holders of Certificates
      of the Class to which this Certificate belongs on such Distribution Date
      pursuant to the Agreement.  The Record Date applicable to each

      funds to the account of the Holder hereof at a bank or other entity having
      appropriate facilities therefor, if such Certificateholder shall have so
      notified the Trustee in writing at least five Business Days prior to the related
      Record Date and such Certificateholder shall satisfy the conditions to receive
      such form of payment set forth in the Agreement, or, if not, by check mailed

      Certificate Register.  The final distribution on each Certificate will
      be made in like manner, but only upon presentment and surrender of such
      Certificate at the Corporate Trust Office or such other location specified
      in
      the notice to Certificateholders of such final distribution.

     

    The
      Agreement permits, with certain exceptions therein provided, the amendment
      thereof and the modification of the rights and obligations of the Trustee and
      the rights of the Certificateholders under the Agreement at any time by the
      Depositor, the Servicer and the Trustee with the consent of the Holders of
      Certificates affected by such amendment evidencing the requisite Percentage
      Interest, as provided in the Agreement.  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 therefor 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
      of
      the Trustee upon surrender of this Certificate for registration of transfer
      at
      the Corporate Trust Office, accompanied by a written instrument of transfer
      in
      form satisfactory to the Trustee and the Certificate Registrar 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 and evidencing the same aggregate Percentage Interest in the
      Trust
      Fund will be issued to the designated transferee or transferees.

    The
      Certificates are issuable only as registered Certificates without coupons in
      denominations 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
      and 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,
      but the Trustee may require payment of a sum sufficient to cover any tax or
      other governmental charge payable in connection therewith.

     

    The
      Depositor, the Servicer, the Seller and the Trustee and any agent of the
      Depositor or the Trustee may treat the Person in whose name this Certificate
      is
      registered as the owner hereof for all purposes, and neither the Depositor,
      the
      Trustee, nor any such agent shall be affected by any notice to the
      contrary.

     

    On
      any
      Distribution Date on which the aggregate Stated Principal Balance of the
      Mortgage Loans is less than 10% of the Cut-off Date Pool Principal Balance,
      the
      Servicer will have the option to repurchase, in whole, from the Trust Fund
      all
      remaining Mortgage Loans and all property acquired in respect of the Mortgage
      Loans at a purchase price determined as provided in the Agreement.  In
      the event that no such optional termination occurs, the related obligations
      and
      responsibilities created by the Agreement will terminate upon the later of
      the
      maturity or other liquidation (or any advance with respect thereto) of the
      last
      Mortgage Loan remaining in the Trust Fund or the disposition of all property
      in
      respect thereof and the distribution to Certificateholders of all amounts
      required to be distributed pursuant to the Agreement.  In no event,
      however, will the trust created by the Agreement continue beyond the expiration
      of 21 years from the death of the last survivor of the descendants living at
      the
      date of the Agreement of a certain person named in the Agreement.

     

    Any
      term
      used herein that is defined in the Agreement shall have the meaning assigned
      in
      the Agreement, and nothing herein shall be deemed inconsistent with that
      meaning.

    Class
      L

     

    evidencing
      a percentage interest in the distributions allocable to the Certificates of
      the
      above-referenced Class with respect to a Trust Fund consisting primarily of
      a
      pool of 30-year conventional adjustable-rate mortgage loans (the “Mortgage
      Loans”) secured by first liens on one- to four-family residential
      properties.

     

    Distributions
      in respect of this Certificate are distributable monthly as set forth
      herein.  Accordingly, the Certificate Balance at any time may be less
      than the Certificate Balance as set forth herein.  This Certificate
      does not evidence an obligation of, or an interest in, and is not guaranteed
      by
      the Depositor, the Seller, the Servicer or the Trustee referred to below or
      any
      of their respective affiliates.  Neither this Certificate nor the
      Mortgage Loans are guaranteed or insured by any governmental agency or
      instrumentality.

     

    This
      certifies that ________________ is the registered owner of the Percentage
      Interest evidenced by this Certificate (obtained by dividing the denomination
      of
      this Certificate by the aggregate of the denominations of all Certificates
      of
      the Class to which this Certificate belongs) in certain monthly distributions
      with respect to a Trust Fund consisting primarily of the Mortgage Loans
      deposited by IndyMac MBS, Inc. (the “Depositor”).  The Trust Fund was
      created pursuant to a Pooling and Servicing Agreement dated as of the Cut-off
      Date specified above (the “Agreement”) among the Depositor, IndyMac Bank,
      F.S.B., as seller and servicer (the “Seller” or the “Servicer”, as
      appropriate),  and Deutsche Bank National Trust Company, as trustee
      (the “Trustee”).  To the extent not defined herein, the capitalized
      terms used herein have the meanings assigned 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 the acceptance hereof assents and by which such Holder is
      bound.

    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 Collection Account 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.

     

    This
      Certificate does not have a Certificate Balance or Pass-Through Rate and will
      be
      entitled to distributions only to the extent set forth in the
      Agreement.  In addition, any distribution of the proceeds of any
      remaining assets of the Trust will be made only upon presentment and surrender
      of this Certificate at the Corporate Trust Office or the office or agency
      maintained by the Trustee.

     

    No
      transfer of a Certificate of this Class shall be made unless such disposition
      is
      exempt from the registration requirements of the Securities Act of 1933, as
      amended (the “1933 Act”), and any applicable state securities laws or is made in
      accordance with the 1933 Act and such laws.  In the event of any such
      transfer, the Trustee shall require the transferor to execute a transferor
      certificate (in substantially the form attached to the Pooling and Servicing
      Agreement) and deliver either (i) an Investment Letter  or the Rule
      144A Letter, in either case substantially in the form attached to the Agreement,
      or (ii) a written Opinion of Counsel to the Trustee that such transfer may
      be
      made pursuant to an exemption, describing the applicable exemption and the
      basis
      therefor, from the 1933 Act or is being made pursuant to the 1933 Act, which
      Opinion of Counsel shall be an expense of the transferor.

     

    No
      transfer of a Certificate of this Class shall be made unless the Trustee shall
      have received either (i) a representation letter from the transferee of such
      Certificate, acceptable to and in form and substance satisfactory to the
      Trustee, to the effect that such transferee is not an employee benefit plan
      or
      arrangement subject to Section 406 of ERISA or Section 4975 of the Code, or
      a
      person investing on behalf of or with plan assets of any such plan, which
      representation letter shall not be an expense of the Trustee, or (ii) if the
      transferee is an insurance company and the Certificates have been the subject
      of
      an ERISA-Qualifying Underwriting, a representation that the purchaser is an
      insurance company which is purchasing such Certificates with funds contained
      in
      an “insurance company general account” (as such term is defined in Section V(e)
      of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and that the
      purchase and holding of such Certificates are covered under Sections I and
      III
      of PTCE 95-60, or (iii) in the case of a Certificate presented for registration
      in the name of an employee benefit plan or arrangement subject to ERISA, or
      a
      plan or arrangement subject to Section 4975 of the Code (or comparable
      provisions of any subsequent enactments), or a trustee of any such plan or
      arrangement or any other person acting on behalf of any such plan or arrangement
      or using such plan’s or arrangement’s assets, an Opinion of Counsel satisfactory
      to the Trustee and addressed to the Trustee and the Servicer, which Opinion
      of
      Counsel shall not be an expense of the Trustee, the Servicer or the Trust Fund,
      to the effect that the purchase and holding of such Certificate will not result

      4975 of the Code and will not subject the Trustee or the Servicer to any
      obligation in addition to those expressly undertaken in this Agreement or to

    Gentlemen:

     

    In
      accordance with Section 2.02 of the above-captioned Pooling and Servicing
      Agreement (the “Pooling and Servicing Agreement”), the undersigned, as Trustee,
      hereby certifies that, as to each Mortgage Loan listed in the Mortgage Loan
      Schedule (other than any Mortgage Loan listed in the attached schedule), it
      has
      received:

     

    (i)  the
      original Mortgage Note, endorsed as provided in the following
      form:  “Pay to the order of ________, without recourse”;
      and

     

    (ii)  an
      executed assignment of the Mortgage (which may be included in a blanket
      assignment or assignments); provided, however, that it has received no
      assignment with respect to any Mortgage for which the Mortgaged Property is
      located in the Commonwealth of Puerto Rico.

     

    Based
      on
      its review and examination and only as to the foregoing documents, such
      documents appear regular on their face and to such Mortgage Loan.

     

    The
      Trustee has made no independent examination of any documents contained in each
      Mortgage File beyond the review specifically required in the Pooling and
      Servicing Agreement.  The Trustee makes no representations as
      to:  (i) the validity, legality, sufficiency, enforceability or
      genuineness of any of the documents contained in each Mortgage File of any
      of
      the Mortgage Loans identified on the Mortgage Loan Schedule, or (ii) the
      collectability, insurability, effectiveness or suitability of any such Mortgage
      Loan.

    Gentlemen:

    Reference
      is made to the Initial Certification of Trustee relating to the above-referenced
      series, with the schedule of exceptions attached thereto (the “Schedule A”),
      delivered by the undersigned, as Trustee, on the Closing Date in accordance
      with
      Section 2.02 of the above-captioned Pooling and Servicing Agreement (the

      that, as to each Delay Delivery Mortgage Loan listed on Schedule A attached
      hereto (other than any Mortgage Loan paid in full or listed on Schedule B
      attached hereto) it has received:

     

    
      	
               

            	
              (i)

            	
              the
                original Mortgage Note, endorsed by the Seller or the originator
                of such
                Mortgage Loan, without recourse in the following form:  “Pay to
                the order of _______________ without recourse”, with all intervening
                endorsements that show a complete chain of endorsement from the originator
                to the Seller, or, if the original Mortgage Note has been lost or
                destroyed and not replaced, an original lost note affidavit from
                the
                Seller, stating that the original Mortgage Note was lost or destroyed,
                together with a copy of the Mortgage
                Note;

            


    

     

    
      	
               

            	
              (ii)

            	
              the
                original recorded Mortgage;

            


    

     

    
      	
               

            	
              (iii)

            	
              an
                executed assignment of the Mortgage to “Deutsche Bank National Trust
                Company, as trustee under the Pooling and Servicing Agreement dated
                as of
                June 1, 2007, without recourse” (each such assignment, when duly and
                validly completed, to be in recordable form and sufficient to effect
                the
                assignment of and transfer to the assignee thereof, under the Mortgage
                to
                which such assignment relates);

                Mortgage;

              the
                original or copies of each assumption, modification, written assurance
                or
                substitution agreement, if any, with evidence of recording thereon
                if
                recordation thereof is permissible under applicable law;
                and

            


    

     

    
      	
               

            	
              (vi)

            	
              the
                original or duplicate original lender’s title policy and all riders, if
                any, thereto or, in the event such original title policy has not
                been
                received from the insurer, any one of an original title binder, an
                original preliminary title report or an original title commitment,
                or a
                copy thereof certified by the title company, with the original policy
                of
                title insurance to be delivered within one year of the Closing
                Date.

            


    

     

    In
      the
      event that in connection with any Mortgage Loan for which the Seller cannot
      deliver the original recorded Mortgage or all interim recorded assignments
      of
      the Mortgage satisfying the requirements of clause (ii), (iii) or (iv), as
      applicable, the Trustee has received, in lieu thereof, a true and complete
      copy
      of such Mortgage and/or such assignment or assignments of the Mortgage, as
      applicable, each certified by the Seller, the applicable title company, escrow
      agent or attorney, or the originator of such Mortgage Loan, as the case may
      be,
      to be a true and complete copy of the original Mortgage or assignment of
      Mortgage submitted for recording.

     

    Based
      on
      its review and examination and only as to the foregoing documents, (i) such
      documents appear regular on their face and related to such Mortgage Loan, and
      (ii) the information set forth in items (i), (iv), (vi) and (xv) (solely as
      of origination, not as of the Cut-off Date) of the definition of the “Mortgage
      Loan Schedule” in Section 1.01 of the Pooling and Servicing Agreement
      accurately reflects information set forth in the Mortgage File.

     

    The
      Trustee has made no independent examination of any documents contained in each
      Mortgage File beyond the review specifically required in the above-referenced
      Pooling and Servicing Agreement.  The Trustee makes no representations
      as to:  (i) the validity, legality, sufficiency, enforceability
      or genuineness of any of the documents contained in each Mortgage File of any
      of
      the Mortgage Loans identified on the [Mortgage Loan Schedule][Loan Number and
      Borrower Identification Mortgage Loan Schedule] or (ii) the collectability,

      Loan.

      located in the Commonwealth of Puerto Rico, or, if the Depositor has certified
      or the Trustee otherwise knows that the Mortgage has not been returned from
      the
      applicable recording office, a copy of the assignment of the Mortgage (excluding
      information to be provided by the recording office).

     

    (iv)  The
      original or duplicate original recorded assignment or assignments of the
      Mortgage showing a complete chain of assignment from the originator to the
      Seller.

      any one of an original title binder, an original preliminary title report or
      an
      original title commitment, or a copy thereof certified by the title
      company.

     

    Based
      on
      its review and examination and only as to the foregoing documents, (a) such
      documents appear regular on their face and related to such Mortgage Loan, and
      (b) the information set forth in items (i), (ii), (iii), (iv), (vi) and (xv)
      (solely as of origination, not as of the Cut-off Date) of the definition of
      the
“Mortgage Loan Schedule” in Section 1.01 of the Pooling and Servicing Agreement
      accurately reflects information set forth in the Mortgage File.

      Servicing Agreement.  The Trustee makes no representations as
      to:  (i) the validity, legality, sufficiency, enforceability or
      genuineness of any of the documents contained in each Mortgage File of any
      of
      the Mortgage Loans identified on the Mortgage Loan Schedule, or (ii) the
      collectability, insurability, effectiveness or suitability of any such Mortgage
      Loan.  Notwithstanding anything herein to the contrary, the Trustee
      has made no determination and makes no representations as to whether (i) any
      endorsement is sufficient to transfer all right, title and interest of the
      party
      so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note
      or
      (ii) any assignment is in recordable form or sufficient to effect the assignment
      of and transfer to the assignee thereof, under the Mortgage to which the
      assignment relates.

    The
      undersigned, being first duly sworn, deposes and says as follows:

     

    1.           The
      undersigned is an officer of
                   ,
      the proposed Transferee of an Ownership Interest in a Class A-R Certificate
      (the
“Certificate”) issued pursuant to the Pooling and Servicing Agreement, (the
“Agreement”), relating to the above-referenced Series, by and among IndyMac MBS,
      Inc., as depositor (the “Depositor”), IndyMac Bank, F.S.B., as seller and
      servicer and Deutsche Bank National Trust Company, as
      Trustee.  Capitalized terms used, but not defined herein or in Exhibit
      1 hereto, shall have the meanings ascribed to such terms in the
      Agreement.  The Transferee has authorized the undersigned to make this
      affidavit on behalf of the Transferee.

     

    2.           The
      Transferee is, as of the date hereof, and will be, as of the date of the
      Transfer, a Permitted Transferee.  The Transferee is acquiring its
      Ownership Interest in the Certificate for its own account.

     

    3.           The
      Transferee has been advised of, and understands that (i) a tax will be imposed
      on Transfers of the Certificate to Persons that are not Permitted Transferees;
      (ii) such tax will be imposed on the transferor, or, if such Transfer is through
      an agent (which includes a broker, nominee or middleman) for a Person that
      is
      not a Permitted Transferee, on the agent; and (iii) the Person otherwise liable
      for the tax shall be relieved of liability for the tax if the subsequent
      Transferee furnished to such Person an affidavit that such subsequent Transferee
      is a Permitted Transferee and, at the time of Transfer, such Person does not
      have actual knowledge that the affidavit is false.

     

    4.           The
      Transferee has been advised of, and understands that a tax will be imposed
      on a
“pass-through entity” holding the Certificate if at any time during the taxable
      year of the pass-through entity a Person that is not a Permitted Transferee
      is
      the record holder of an interest in such entity.  The Transferee
      understands that such tax will not be imposed for any period with respect to
      which the record holder furnishes to the pass-through entity an affidavit that
      such record holder is a Permitted Transferee and the pass-through entity does
      not have actual knowledge that such affidavit is false.  (For this
      purpose, a “pass-through entity” includes a regulated investment company, a real
      estate investment trust or common trust fund, a partnership, trust or estate,
      and certain cooperatives and, except as may be provided in Treasury Regulations,
      persons holding interests in pass-through entities as a nominee for another
      Person.)

     

    5.           The
      Transferee has reviewed the provisions of Section 5.02(c) of the Agreement
      (attached hereto as Exhibit 2 and incorporated herein by reference) and
      understands the legal consequences of the acquisition of an Ownership Interest
      in the Certificate including, without limitation, the restrictions on subsequent
      Transfers and the provisions regarding voiding the Transfer and mandatory
      sales.  The Transferee expressly agrees to be bound by and to abide by
      the provisions of Section 5.02(c) of the Agreement and the restrictions noted
      on
      the face of the Certificate.  The Transferee understands and agrees
      that any breach of any of the representations included herein shall render
      the
      Transfer to the Transferee contemplated hereby null and void.

     

    
      
        
        

      

      
        I-1

        
          

        

      

      
        
        

      

    

     

    6.           The
      Transferee agrees to require a Transfer Affidavit from any Person to whom the
      Transferee attempts to Transfer its Ownership Interest in the Certificate,
      and
      in connection with any Transfer by a Person for whom the Transferee is acting
      as
      nominee, trustee or agent, and the Transferee will not Transfer its Ownership
      Interest or cause any Ownership Interest to be Transferred to any Person that
      the Transferee knows is not a Permitted Transferee.  In connection
      with any such Transfer by the Transferee, the Transferee agrees to deliver
      to
      the Trustee a certificate substantially in the form set forth as Exhibit J
      to
      the Agreement (a “Transferor Certificate”) to the effect that such Transferee
      has no actual knowledge that the Person to which the Transfer is to be made
      is
      not a Permitted Transferee.

     

    7.           The
      Transferee does not have the intention to impede the assessment or collection
      of
      any tax legally required to be paid with respect to the
      Certificate.

     

    8.           The
      Transferee’s taxpayer identification number is
           .

     

    9.           The
      Transferee is a U.S. Person as defined in Code Section 7701(a)(30).

     

    10.           The
      Transferee is aware that the Certificate may be a “noneconomic residual
      interest” within the meaning of proposed Treasury regulations promulgated
      pursuant to the Code and that the transferor of a noneconomic residual interest
      will remain liable for any taxes due with respect to the income on such residual
      interest, unless no significant purpose of the transfer was to impede the
      assessment or collection of tax.

     

    11.           The
      Transferee is not a foreign permanent establishment or fixed base (within the
      meaning of an applicable income tax treaty) of a U.S. taxpayer.

     

    12.           The
      Transferee will not transfer the Certificates, directly or indirectly, to a
      foreign permanent establishment or fixed base (within the meaning of an
      applicable income tax treaty) of the Transferee or another U.S.
      taxpayer.

     

    13.           The
      Transferee will not cause income from the Certificates to be attributable to
      a
      foreign permanent establishment or fixed base (within the meaning of an
      applicable income tax treaty) of the Transferee or another U.S.
      taxpayer.

     

    14.           Either:

     

    (a)
      (i)
      At the time of the transfer, and at the close of each of the Transferee’s two
      fiscal years preceding the Transferee’s fiscal year of transfer, the
      Transferee’s gross assets for financial reporting purposes exceed $100 million
      and its net assets for financial reporting purposes exceed $10 million. For
      purposes of the preceding sentence, the gross assets and net assets of a
      Transferee do not include any obligation of any Related Person, as defined
      below, or any other asset if a principal purpose for holding or acquiring the
      other asset is to permit the Transferee to satisfy the conditions of this
      paragraph 15(a); (ii) The Transferee is an Eligible Corporation, as defined
      below, and hereby agrees that any subsequent transfer of the interest will
      be to
      another Eligible Corporation in a transaction that satisfies this Transfer
      Affidavit, including this paragraph 15(a); and (iii) The Transferee has not
      given the Transferor any reason to know that the Transferee will not honor
      the
      restrictions on subsequent transfers of the residual interest or that the
      Transferee cannot or will not pay any taxes associated with the residual
      interest; or

     

    
      
        
        

      

      
        I-2

        
          

        

      

      
        
        

      

    

    (b)(i)
      The Transferee is a United States Person; (ii) The present value of the
      anticipated tax liabilities associated with holding the residual interest does
      not exceed the sum of: (A) The present value of any consideration given to
      the
      Transferee to acquire the interest; (B) The present value of the expected future
      distributions on the interest; and (C) The present value of the anticipated
      tax
      savings associated with holding the interest as any REMIC generates losses;
      and
      (iii) For purposes of calculating the aforementioned present values: (A) The
      transferee has assumed that it pays tax at a rate equal to the highest rate
      of
      tax specified in Code Section 11(b)(1) (unless the Transferee has been subject
      to the alternative minimum tax under Code Section 55 in the preceding two years
      and will compute its taxable income in the current taxable year using the
      alternative minimum tax rate, in which case the Transferee can assume that
      it
      pays tax at the rate specified in Code Section 55(b)(1)(B) provided the
      Transferee states in this Transfer Affidavit that it is using such alternate
      rate and that has been subject to the alternative minimum tax under Code Section
      55 in the preceding two years and will compute its taxable income in the current
      taxable year using the alternative minimum tax rate):and (B) The Transferee
      uses
      a discount rate equal to the Federal short-term rate prescribed by section
      1274(d) for the month of the transfer and the compounding period used by the
      Transferee.

     

    The
      term
“Eligible Corporation” means any domestic C corporation (as defined in section
      1361(a)(2) of the Code) other than a corporation which is exempt from, or is
      not
      subject to, tax under section 11 of the Code, an entity described in section
      851(a) or 856(a) of the Code, a REMIC; or an organization to which part I,
      subchapter T, chapter 1, subtitle A of the Code applies.  The Term
“Related Person” means any person that bears a relationship to the Transferee
      enumerated in section 267(b) or 707(b)(1) of the Code, using "20 percent"
      instead of "50 percent" where it appears under the provisions; or is under
      common control (within the meaning of section 52(a) and (b) of the Code) with
      the Transferee.

     

    15.           Either
      (i) the Transferee is not an employee benefit plan that is subject to ERISA
      or a
      plan that is subject to Section 4975 of the Code, and the Transferee is not
      acting on behalf of or with plan assets of such a plan; or (ii) the Transferee
      is an insurance company that is investing funds contained in an “insurance
      company general account” (as such term is defined in Section V(e) of Prohibited
      Transaction Class Exemption 95-60 (“PTCE 95-60”) and the purchase and holding of
      the Class A-R Certificate satisfy the requirements for exemptive relief under
      Sections I and III of PTCE 95-60.

      1

    Certain
      Definitions

     

    “Ownership
      Interest”:  As to any Certificate, any ownership interest in such
      Certificate, including any interest in such Certificate as the Holder thereof
      and any other interest therein, whether direct or indirect, legal or
      beneficial.

     

    “Permitted
      Transferee”:  Any Person other than (i) the United States, any State
      or political subdivision thereof, or any agency or instrumentality of any of
      the
      foregoing, (ii) a foreign government, International Organization or any agency
      or instrumentality of either of the foregoing, (iii) an organization (except
      certain farmers’ cooperatives described in Code Section 521) that is exempt from
      tax imposed by Chapter 1 of the Code (including the tax imposed by Code Section
      511 on unrelated business taxable income) on any excess inclusions (as defined
      in Code Section 860E(c)(1)) with respect to any Restricted Certificate, (iv)
      a
      rural electric and telephone cooperatives described in Code Section
      1381(a)(2)(c), (v) an “electing large partnership” as defined in Code Section
      775 of (vi) a Person that is not a U.S. Person, and (vii) any other Person
      so
      designated by the Depositor based upon an Opinion of Counsel that the Transfer
      of an Ownership Interest in a Residual Certificate to such Person may cause
      any
      REMIC to fail to qualify as a REMIC at any time that certain Certificates are
      Outstanding.  The terms “United States,” “State” and “International
      Organization” shall have the meanings set forth in Code Section 7701 or
      successor provisions.  A corporation will not be treated as an
      instrumentality of the United States or of any State or political subdivision
      thereof if all of its activities are subject to tax, and, with the exception
      of
      the FHLMC, a majority of its board of directors is not selected by such
      governmental unit.

     

    “Person”:  Any
      individual, corporation, partnership, joint venture, limited liability company,
      bank, joint stock company, trust (including any beneficiary thereof),
      unincorporated organization or government or any agency or political subdivision
      thereof.

     

    “Transfer”:  Any
      direct or indirect transfer or sale of any Ownership Interest in a Certificate,
      including the acquisition of a Certificate by the Depositor.

     

    “Transferee”:  Any
      Person who is acquiring by Transfer any Ownership Interest in a
      Certificate.

    Section
      5.02(c) of the Agreement

     

    (c)  Each
      Person who has or who acquires any Ownership Interest in a Residual Certificate
      shall be deemed by the acceptance or acquisition of such Ownership Interest
      to
      have agreed to be bound by the following provisions, and the rights of each
      Person acquiring any Ownership Interest in a Residual Certificate are expressly
      subject to the following provisions:

     

    (i)  Each
      Person holding or acquiring any Ownership Interest in a Residual Certificate
      shall be a Permitted Transferee and shall promptly notify the Trustee of any
      change or impending change in its status as a Permitted Transferee.

     

    (ii)  No
      Ownership Interest in a Residual Certificate may be registered on the Closing
      Date or thereafter transferred, and the Trustee shall not register the Transfer
      of any Residual Certificate unless, in addition to the certificates required
      to
      be delivered to the Trustee under subparagraph (b) above, the Trustee shall
      have
      been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner
      or the proposed transferee in the form attached hereto as Exhibit
      I.

     

    (iii)  Each
      Person holding or acquiring any Ownership Interest in a Residual Certificate
      shall agree (A) to obtain a Transfer Affidavit from any other Person to whom
      such Person attempts to Transfer its Ownership Interest in a Residual
      Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such
      Person is acting as nominee, trustee or agent in connection with any Transfer
      of
      a Residual Certificate and (C) not to Transfer its Ownership Interest in a
      Residual Certificate or to cause the Transfer of an Ownership Interest in a
      Residual Certificate to any other Person if it has actual knowledge that such
      Person is not a Permitted Transferee.

     

    (iv)  Any
      attempted or purported Transfer of any Ownership Interest in a Residual
      Certificate in violation of the provisions of this Section 5.02(c) shall be
      absolutely null and void and shall vest no rights in the purported
      Transferee.  If any purported transferee shall become a Holder of a
      Residual Certificate in violation of the provisions of this Section 5.02(c),
      then the last preceding Permitted Transferee shall be restored to all rights
      as
      Holder thereof retroactive to the date of registration of Transfer of such
      Residual Certificate.  The Trustee shall be under no liability to any
      Person for any registration of Transfer of a Residual Certificate that is in
      fact not permitted by Section 5.02(b) and this Section 5.02(c) or for making
      any
      payments due on such Certificate to the Holder thereof or taking any other
      action with respect to such Holder under the provisions of this Agreement so
      long as the Transfer was registered after receipt of the Transfer Affidavit,
      Transferor Certificate and either the Rule 144A Letter or the Investment
      Letter.  The Trustee shall be entitled but not obligated to recover
      from any Holder of a Residual Certificate that was in fact not a Permitted
      Transferee at the time it became a Holder or, at such subsequent time as it
      became other than a Permitted Transferee, all payments made on such Residual
      Certificate at and after either such time.  Any such payments so
      recovered by the Trustee shall be paid and delivered by the Trustee to the
      last
      preceding Permitted Transferee of such Certificate.

     

    (v)  The
      Depositor shall use its best efforts to make available, upon receipt of written
      request from the Trustee, all information necessary to compute any tax imposed
      under Section 860E(e) of the Code as a result of a Transfer of an Ownership
      Interest in a Residual Certificate to any Holder who is not a Permitted
      Transferee.

      (c)
      to the extent we are disposing of a Class A-R Certificate, we have no knowledge

      Act, (g) we will not sell, transfer or otherwise dispose of any Certificates
      unless (1) such sale, transfer or other disposition is made pursuant to an
      effective registration statement under the Act or is exempt from such
      registration requirements, and if requested, we will at our expense provide
      an

    ___           Small
      Business Investment Company.  Buyer is a small business investment
      company licensed by the U.S. Small Business Administration under Section 301(c)
      or (d) of the Small Business Investment Act of 1958.

     

    ___           Business
      Development Company.  Buyer is a business development company as
      defined in Section 202(a)(22) of the Investment Advisors Act of
      1940.

     

    3.  The
      term “securities” as used herein does not include (i) securities of issuers that
      are affiliated with the Buyer, (ii) securities that are part of an unsold
      allotment to or subscription by the Buyer, if the Buyer 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 Buyer, the Buyer used the cost of such
      securities to the Buyer and did not include any of the securities referred
      to in
      the preceding paragraph, except (i) where the Buyer reports its securities
      holdings in its financial statements on the basis of their market value, and
      (ii) no current information with respect to the cost of those securities has
      been published.  If clause (ii) in the preceding sentence applies, the
      securities may be valued at market.  Further, in determining such
      aggregate amount, the Buyer may have included securities owned by subsidiaries
      of the Buyer, but only if such subsidiaries are consolidated with the Buyer
      in
      its financial statements prepared in accordance with generally accepted
      accounting principles and if the investments of such subsidiaries are managed
      under the Buyer’s direction.  However, such securities were not
      included if the Buyer is a majority-owned, consolidated subsidiary of another
      enterprise and the Buyer is not itself a reporting company under the Securities
      Exchange Act of 1934, as amended.

     

    5.  The
      Buyer acknowledges that it is familiar with Rule 144A and understands that
      the
      seller to it 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
      Buyer may be in reliance on Rule 144A.

     

    6.  Until
      the date of purchase of the Rule 144A Securities, the Buyer 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
      Buyer’s purchase of the Certificates will constitute a reaffirmation of this
      certification as of the date of such purchase.  In addition, if the
      Buyer is a bank or savings and loan is provided above, the Buyer agrees that
      it
      will furnish to such parties updated annual financial statements promptly after
      they become available.

      Rule 144A Transferee Certificate to which this certification relates are relying
      and will continue to rely on the statements made herein because one or more
      sales to the Buyer will be in reliance on Rule 144A.  In addition, the
      Buyer will only purchase for the Buyer’s own account.

     

    
      
        
        

      

      
        L-3

    I,
      ____________________, a duly elected and acting officer of Deutsche Bank
      National Trust Company (the “Trustee”) hereby certify as follows:

     

    Reference
      is hereby made to the Pooling and Servicing Agreement dated as of June 1, 2007

      meanings assigned to them in the Pooling Agreement.

     

    1.           I
      am an authorized officer of the Trustee and I have reviewed this annual report
      on Form 10-K and all reports on Form 10-D required to be filed in respect of

      Act Periodic Reports”);

     

    2.           For
      purposes of this certificate, “Relevant Information” means the information in

      set forth in Item 1122(d) of Reg AB (the “Servicing Assessment”), the registered
      public accounting firm’s attestation provided in accordance with Rules 13a-18

      and Servicing Agreement which indicate the 4.06 statement or the Trustee as
      the
      responsible party during the Relevant Year. Based on my knowledge, the Relevant
      Information, taken as a whole, does not contain any untrue statement of a
      material fact or omit to state a material fact necessary to make the statements
      made, in light of the circumstances under which such statements were made,
      not

    4.           I
      am responsible for reviewing the activities performed by the Trustee, as
      servicer under the Pooling Agreement during the Relevant Year. Based upon the
      review required by the Pooling Agreement and except as disclosed in the
      Servicing Assessment or Attestation Report, to the best of my knowledge, the
      Trustee has fulfilled its obligations under the Pooling Agreement throughout

    I,
      ________________________________, the _______________________ of the Trustee
      (the “Trustee”), certify to the Depositor and the
      Servicer, and their officers, with the knowledge and intent that they will
      rely
      upon this certification, that:

     

    (i)           I
      have reviewed the report on assessment of the Trustee’s compliance with the
      servicing criteria set forth in Item 1122(d) of Regulation AB (the
“Servicing Criteria”), provided in accordance with
      Rules 13a-18 and 15d-18 under Securities Exchange Act of 1934, as amended (the
      “Exchange Act”) and Item 1122 of Regulation AB (the
“Servicing Assessment”), the registered public
      accounting firm’s attestation report provided in accordance with Rules 13a-18
      and 15d-18 under the Exchange Act and Section 1122(b) of Regulation AB (the
      “Attestation Report”), all reports on Form 10-D
      containing statements to certificateholders filed in respect of the period
      included in the year covered by the annual report of the Trust Fund
      (collectively, the “Distribution Date
      Statements”);

     

    (ii)           Assuming
      the accuracy and completeness of the information delivered to the Trustee by
      the
      Servicer as provided in the Pooling and Servicing Agreement and subject to
      paragraph (iv) below, to its knowledge the distribution information determined
      by the Trustee and set forth in the Distribution Date Statements contained
      in
      all Form 10-D’s included in the year covered by the annual report of such Trust
      on Form 10-K for the calendar year 200[  ], is complete and does not
      contain any material misstatement of fact as of the last day of the period
      covered by such annual report;

     

    (iii)           Based
      solely on the information delivered to the Trustee by the Servicer as provided
      in the Pooling and Servicing Agreement, the distribution information required
      under the Pooling and Servicing Agreement to be contained in the Trust Fund’s
      Distribution Date Statements is included in such Distribution Date
      Statements;

     

    (iv)           The
      Trustee is not certifying as to the accuracy, completeness or correctness of
      the
      information which it received from the Servicer and did not independently verify
      or confirm the accuracy, completeness or correctness of the information provided
      by the Servicer;

     

    (v)           I
      am responsible for reviewing the activities performed by the Trustee as a person
      “performing a servicing function” under the Pooling and Servicing Agreement, and
      based on my knowledge and the compliance review conducted in preparing the
      Servicing Assessment and except as disclosed in the Servicing Assessment or
      the
      Attestation Report, the Trustee has fulfilled its obligations under the Pooling
      and Servicing Agreement; and

     

    (vi)           The
      Servicing Assessment and Attestation Report required to be provided by the
      Trustee and by Subcontractor, if any, pursuant to the Pooling and Servicing
      Agreement, have been provided to the Servicer and the Depositor.  Any
      material instances of noncompliance described in such reports have been
      disclosed to the Servicer and the Depositor.  Any material instance of
      noncompliance with the Servicing Criteria has been disclosed in such
      reports.
