      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 Holders of the Class L Certificates) 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 or through any REMIC created
        under
        this Agreement.  All amounts in respect of waived Late Payment Fees
        paid by the Servicer to the Holders of the Class L Certificates will be treated
        as paid directly by the Servicer to the Class L Certificates pursuant to
        Section
        3.21(b) and not as paid through any REMIC created under this Agreement or
        by or
        through the Grantor Trust described in this Agreement.

       

      REMIC

      The
        REMIC
        1 Regular Interests will have the initial principal balance, Pass-Through
        Rates
        and corresponding Loan Groups as set forth in the following table:

      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 the
        REMIC.  For purposes of calculating the Pass-Through Rates for each of
        the interests issued by 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.

      (i)           A

      (iii)           a
        partnership (or entity treated as a partnership for tax purposes) organized
        in
        the United States or under the laws of the United States or of any state

      Section
        1.02                                Rules
        of Construction.

       

      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
        amendments, modifications, supplements, or any other changes that may have
        occurred since the document, statute, rule, or regulation came into being,
        including changes that occur after the date of this Agreement.

       

      (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.

       

      
        
          
          

        

        
          34

          
            

          

        

        
          
          

        

      

      (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.

      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;

      (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.

      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.

       

      
        
          
          

        

        
          37

          
            

          

        

        
          
          

        

      

      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

       

      
        
          
          

        

        
          38

          
            

          

        

        
          
          

        

      

      (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 Properties 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 hereof 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.

       

      
        
          
          

        

        
          39

          
            

          

        

        
          
          

        

      

      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 clause (a) above or purchase pursuant to clause
        (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 clause
        (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.

       

      
        
          
          

        

        
          40

          
            

          

        

        
          
          

        

      

      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.

       

      
        
          
          

        

        
          41

          
            

          

        

        
          
          

        

      

      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.

        2.06                                Execution
        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
        3.02                                [Reserved].

      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.

      (b)  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 the Prepayment
        Interest Excess and of 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;

       

      (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

       

      
        
          
          

        

        
          47

          
            

          

        

        
          
          

        

      

      (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.

       

      (c)  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.

       

      (d)  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.

      (e)  [Reserved].

       

      (f)  [Reserved].

       

      (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.

        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

        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;

        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;

      (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.

      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.

       

      
        
          
          

        

        
          52

          
            

          

        

        
          
          

        

      

      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.

       

      
        
          
          

        

        
          53

          
            

          

        

        
          
          

        

      

      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.

       

      
        
          
          

        

        
          54

          
            

          

        

        
          
          

        

      

      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 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
        policy or bond from an insurer or issuer meeting the above requirements as
        of
        the date of the 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 upon actual knowledge by 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.

        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 a 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) 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.

        4.02                                Priorities
        of Distribution.

       

      (a)  On
        each Distribution Date, the Trustee shall withdraw the Available Funds from
        the
        Distribution Account and apply such funds to distributions on the Certificates
        in the following priority, in each case, to the extent of Available Funds
        remaining:

       

      (i)           concurrently,
        to each interest-bearing Class of Senior Certificates, an amount allocable
        to
        interest equal to the related Class Optimal Interest Distribution Amount,
        any
        shortfall being allocated among such Classes in proportion to the amount
        of the
        Class Optimal Interest Distribution Amount that would have been distributed
        in
        the absence of such shortfall;

       

      (ii)           [reserved];

       

      (iii)           concurrently,
        to each Class of Senior Certificates as follows:

       

      
        	
                 

              	
                (A)

              	
                [reserved];
                  and

              


      

       

      
        	
                 

              	
                (B)

              	
                on
                  each Distribution Date, the Principal Amount, up to the amount
                  of the
                  Senior Principal Distribution Amount for such Distribution Date
                  will be

      (b)  [reserved].

       

      (c)  On

        notwithstanding the allocation and priority set forth in Section 4.02(a)(iii),
        the Principal Amount up to the amount of the related Senior Principal
        Distribution Amount for such Distribution Date will be distributed concurrently,
        as principal, of the Classes of Senior Certificates, pro rata, on the basis
        of
        their respective Class Certificate Balances, until the Class Certificate
        Balances thereof are reduced to zero.

      (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 the related Class Optimal
        Interest Distribution Amount 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 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 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 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), 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)(vi).  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 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 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.

        follows:

       

      (i)             [reserved];
        and

       

      (A)
        any
        Realized Loss (other than any Excess Loss) on the Mortgage Loans 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, second, sequentially, to the Class A-2 and Class A-1
        Certificates, in that order, until their respective Class Certificate Balances
        are reduced to zero.

       

      (B)
        on
        each Distribution Date, Excess Losses on the Mortgage Loans shall be allocated
        pro rata among the Classes of Senior Certificates on the basis of 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
        Trustee’s responsibility for disbursing the above information to
        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

        (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
        shall
        cause to be furnished to each Person who at any time during the calendar
        year
        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.

       

      Section
        4.07                                [Reserved].

       

      Section
        4.08                                [Reserved].

       

      Section
        4.09                                Determination
        of Pass-Through Rates for LIBOR Certificates.

       

      On
        each
        LIBOR Determination Date so long as the LIBOR Certificates are outstanding,
        the
        Trustee will determine LIBOR on the basis of the British Bankers’ Association
        (“BBA”) “Interest Settlement Rate” for one-month
        deposits in U.S. dollars as found on Reuters Page LIBOR01 as of 11:00 a.m.
        London time on each LIBOR Determination Date.

       

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

       

      (b)  LIBOR
        for the next Interest Accrual Period for a Class of LIBOR Certificates will
        be
        established by the Trustee on each LIBOR Determination Date as
        follows:

       

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

       

      
        
          
          

        

        
          67

          
            

          

        

        
          
          

        

      

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

       

      (iii)           If
        on any LIBOR Determination Date the Trustee is required but is unable to
        determine the Reserve Interest Rate in the manner provided in paragraph (b)
        above, LIBOR shall be LIBOR as determined on the preceding LIBOR Determination
        Date, or, in the case of the first LIBOR Determination Date, the Initial
        LIBOR
        Rate.

       

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

       

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

       

      (e)           In
        determining LIBOR, any Pass-Through Rate for the LIBOR Certificates, any
        Interest Settlement Rate, or any Reserve Interest Rate, the Trustee may
        conclusively rely and shall be protected in relying upon the offered quotations
        (whether written, oral or on the Dow Jones Markets) from the BBA designated
        banks, the Reference Banks or the New York City banks as to LIBOR, the Interest
        Settlement Rate or the Reserve Interest Rate, as appropriate, in effect from
        time to time.  The Trustee shall not have any liability or
        responsibility to any Person for (i) the Trustee’s selection of New York City
        banks for purposes of determining any Reserve Interest Rate or (ii) its
        inability, following a good-faith reasonable effort, to obtain such quotations
        from, the BBA designated banks, the Reference Banks or the New York City
        banks
        or to determine such arithmetic mean, all as provided for in this Section
        4.08.

       

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

       

      (g)  The
        Pass-Through Rate for the Interest Accrual Period for the first Distribution
        Date for each Class of LIBOR Certificates is set forth in the applicable
        footnote under the heading “Master REMIC” in the Preliminary
        Statement.

      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.

      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.

      (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
        Deemed Owners.

       

      The
        Servicer, the Trustee, and any agent of the Servicer or the Trustee may treat
        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.

       

      Section
        5.05                                Access
        to List of Certificateholders’ Names and Addresses.

       

      If
        three
        or more Certificateholders and/or Certificate Owners (a) request such
        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.

        5.06                                Maintenance
        of Office or Agency.

       

      The
        Certificate Registrar will maintain at its expense an office or offices or

      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
        6.04                                Limitation
        on Resignation of the Servicer.

       

      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.

      Default

       

      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.

      In
        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

        appropriate recording office.  The successor Servicer shall cause such
        assignment to be delivered to the Trustee promptly upon receipt of the original

        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;

       

      
        
          
          

        

        
          78

          
            

          

        

        
          
          

        

      

      (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

       

      
        
          
          

        

        
          79

          
            

          

        

        
          
          

        

      

      (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

       

      
        
          
          

        

        
          80

          
            

          

        

        
          
          

        

      

      (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.

      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.

       

      Section
        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;

       

      
        
          
          

        

        
          83

          
            

          

        

        
          
          

        

      

      (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;

       

      
        
          
          

        

        
          84

          
            

          

        

        
          
          

        

      

      (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.

       

      
        
          
          

        

        
          85

          
            

          

        

        
          
          

        

      

      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

      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.

        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.

      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 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,

      (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.

        purpose of facilitating the recordation of this Agreement as herein provided
        and
        for other purposes, this Agreement may be executed simultaneously in any

        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

      2.  The

        of
        any successor;

       

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

       

      5.  The
        final distribution to Certificateholders.

        deemed to have been duly given when delivered to (a) in the case of the

        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.

       

      
        
          
          

        

        
          93

          
            

          

        

        
          
          

        

      

      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
        for transactions and activities entered into in connection with the
        securitization that is the subject of this Agreement, the trust created by
        this
        Agreement is not authorized and has no power to:

       

      (1)           borrow
        money or issue debt;

       

      (2)           merge
        with another entity, reorganize, liquidate or sell assets;

       

      (3)           engage
        in any business or activities.

       

      (b)  Each
        party to this Agreement agrees that it will not file an involuntary bankruptcy
        petition against the Trustee or the Trust Fund or initiate any other form
        of
        insolvency proceeding until after the Certificates have been paid in
        full.

       

      Section
        10.13                                Qualifying
        Special Purpose Entity.

       

      Notwithstanding
        any contrary provision of this Agreement, the Trust Fund shall not hold any
        property or engage in any activity that would disqualify the Trust Fund from
        being a qualifying special purpose entity under generally accepted accounting
        principles.

      Section
        11.01                                Filing
        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

      (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

      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

        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
        Act.  The Trustee shall prepare each Form 10-K and, no later than 5
        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
        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-K. The Trustee
        shall
        make any changes thereto requested by the Depositor and deliver the final

        Compliance, Attestation Report, Annual Compliance Statements and other
        documentation provided by the Servicer pursuant to Sections 3.17 and 11.07,
        a
        certification in the form attached hereto as Exhibit O-1 (the “Depositor
        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
        Distribution Date. In the case of  information to be included in the
        Form 8-K, such information shall be delivered to the Depositor no later than
        no
        later 2 Business Days following the occurrence of a reportable
        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
        preceding Business Day).

       

      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.

       

      Section
        11.06                                Form
        15 Filing.

       

      Prior
        to
        January 30 of the first year in which the Depositor is able to do so under
        applicable law, the Trustee on behalf of the Depositor shall file a Form
        15
        relating to the automatic suspension of reporting in respect of the Trust
        Fund
        under the Exchange Act.

       

      Section
        11.07                                Report
        on Assessment of Compliance and Attestation.

       

      (a)  On
        or 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.

      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.

        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

        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)

        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

        of or
        compliance with the terms thereof are in the ordinary course of business

        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,

        is
        not in breach or violation of any material indenture or other material agreement

        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
        or violation may materially impair IndyMac’s ability to perform or meet any of
        its obligations under the Pooling and Servicing Agreement.

      IndyMac

      Mortgage
        Pass-Through Certificates,

      Series
        2007-AR17

       

      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
        Securities Exchange Act of 1934, as amended) by an entity that satisfied
        at the
        time of origination the requirements of Section 3(a)(41) of the Securities
        Exchange Act of 1934, as amended.

       

      (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)
        As
        of 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 of the related Mortgaged Property 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)
        No
        more than 0.09% of the Mortgage Loans 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 Oct. 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

        or
        the Trustee referred to below or any of their respective

        Fund consisting primarily of the Mortgage Loans deposited by IndyMac MBS,
        Inc.

        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

      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.

       

      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 evidenced by this
        Certificate (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 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 (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.

       

      [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.]

        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, 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 the Servicer,

        of such Certificate will not result in a nonexempt prohibited transaction

        Section 406 of ERISA or Section 4975 of the Code and will not subject the

        the

        that
        the purchaser is an insurance company which is purchasing such Certificates

        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

        plan

        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

      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.

      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.

      Class
        P

       

      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.

      Mortgage
        Pass-Through Certificates

       

      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
        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
        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.

       

      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.

      evidencing
        a percentage interest in the distributions allocable to the Certificates
        of the
        above-referenced Class payable solely from Late Payment Fees.

      


      Distributions
        in respect of this Certificate are distributable monthly 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
        pursuant to a Pooling and Servicing Agreement dated as of the Cut-off Date
        specified above (the “Agreement”) among IndyMac MBS, Inc., as depositor (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.

       

      This
        Certificate does not have a Pass-Through Rate and will be entitled to
        distributions only to the extent set forth in the Agreement and solely payable
        from Late Payment Fees.  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 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, subject to the provisions in Section 5.02(b) of the Agreement,
        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.]

        is hereby made to the further provisions of this Certificate set forth on

        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

        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

        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.

      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.

       

      Capitalized
        words and phrases used herein shall have the respective meanings assigned
        to
        them in the Pooling and Servicing Agreement.

                  received from the insurer, any one of an original title binder,
                  an

                  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

      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 paid in full or listed on the attached
        Document Exception Report) it has received:

       

      (i)  The
        original Mortgage Note, endorsed in the form provided in Section 2.01(c)
        of the

        complete chain of endorsement from the originator to the Seller.

       

      (ii)  The
        original recorded Mortgage.

       

      (iii)  An
        executed assignment of the Mortgage in the form provided in Section 2.01(c)
        of
        the Pooling and Servicing Agreement; 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, 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.

       

      (v)  The
        original or duplicate original lender’s title policy and all riders thereto or,
        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

      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

        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

      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

      (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.

      EXHIBIT
        1

      to
        EXHIBIT I

       

      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.

        2

      to
        EXHIBIT I

       

      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.

        the Transferee is not a Permitted Transferee.

      Ladies
        and Gentlemen:

       

      In
        connection with our acquisition of the above-referenced Certificates we certify
        that (a) we understand that the Certificates are not being registered under
        the
        Securities Act of 1933, as amended (the “Act”), or any state securities laws and
        are being transferred to us in a transaction that is exempt from the
        registration requirements of the Act and any such laws, (b) we are an
“accredited investor,” as defined in Regulation D under the Act, and have such
        knowledge and experience in financial and business matters that we are capable
        of evaluating the merits and risks of investments in the Certificates, (c)
        we
        have had the opportunity to ask questions of and receive answers from the
        Depositor concerning the purchase of the Certificates and all matters relating
        thereto or any additional information deemed necessary to our decision to
        purchase the Certificates, (d) either (i) we are not an employee benefit
        plan
        that is subject to the Employee Retirement Income Security Act of 1974, as
        amended, or a plan or arrangement that is subject to Section 4975 of the
        Internal Revenue Code of 1986, as amended, nor are we acting on behalf of
        any
        such plan or arrangement or using the assets of any such plan or arrangement
        to
        effect such acquisition or (ii) [in the case of a Certificate that has been
        the
        subject of an ERISA-Qualifying Underwriting] we are 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 the purchase and holding
        of such Certificates are covered under Sections I and III of PTCE 95-60,
        (e) we
        are acquiring the Certificates for investment for our own account and not
        with a
        view to any distribution of such Certificates (but without prejudice to our
        right at all times to sell or otherwise dispose of the Certificates in
        accordance with clause (g) below), (f) we have not offered or sold any
        Certificates to, or solicited offers to buy any Certificates from, any person,
        or otherwise approached or negotiated with any person with respect thereto,
        or
        taken any other action which would result in a violation of Section 5 of
        the
        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
        opinion of counsel satisfactory to the addressees of this Certificate that
        such
        sale, transfer or other disposition may be made pursuant to an exemption
        from
        the Act, (2) the purchaser or transferee of such Certificate has executed
        and
        delivered to you a certificate to substantially the same effect as this
        certificate, and (3) the purchaser or transferee has otherwise complied with
        any
        conditions for transfer set forth in the Pooling and Servicing Agreement
        and (h)
        if we are a corporation purchasing the Certificates in the State of California,
        we have a net worth of at least $14,000,000 according to our most recent
        audited
        financial statements.

      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

        holdings in its financial statements on the basis of their market value,

        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.

        Buyer is familiar with Rule 144A and understands that the parties listed
        in the
        Rule 144A Transferee Certificate to which this certification relates are

      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
        (the “Pooling Agreement”) by and among IndyMac Bank, F.S.B., as seller and

        Company, as trustee, pursuant to which was created the IndyMac INDX Mortgage

(the “Trust”). Capitalized terms used herein but not defined shall have the
        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 the
        period covered by this report on Form 10-K of IndyMac INDX Mortgage Loan
        Trust
        200 -   , Series 200 -    (the “Exchange
        Act Periodic Reports”);

       

      2.           For
        purposes of this certificate, “Relevant Information” means the information in
        the report on assessment of the Trustee’s compliance with the servicing criteria
        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

“Attestation Report”) applicable to the Trustee and the Monthly Statements
        (excluding information provided, or based on information provided, by the
        Servicer or any servicer) and those items in Exhibit S attached to the Pooling
        and Servicing Agreement which indicate the 4.03 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
        misleading with respect to the period covered by this annual report;
        and

       

      3.           Based
        on my knowledge, the distribution information required to be provided by
        the
        Trustee under the Pooling and Servicing Agreement is included in the Monthly
        Statements.

       

      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
        the
        Relevant Year. Relevant Year shall mean 200__.
