      permitted by this Indenture.

     

    The

      borders).

     

    The
      terms
      of the Notes set forth in Exhibits A-1, A-2 and A-3 to this Indenture are part

      The

    Notes
      bearing the manual or facsimile signature of individuals who were at any time
      Authorized Officers of the Issuing Entity shall bind the Issuing Entity,

    Section
      2.03  Acceptance
      of Mortgage Loans by Indenture Trustee.

     

    (a)  The
      Indenture Trustee shall acknowledge receipt of, subject to the exceptions the
      Indenture Trustee notes pursuant to the procedures described below, the
      documents (or certified copies thereof) referred to in Section 2.1(b) of the
      Mortgage Loan Purchase Agreement, and to declare that it holds and will continue
      to hold those documents and any amendments, replacements or supplements thereto
      and all other assets of the Trust Estate, in trust for the use and benefit
      of
      all present and future Holders of the Notes. No later than the Closing Date,
      with respect to the Mortgage Loans (or, with respect to any Eligible Substitute
      Mortgage Loan, within 5 days after the receipt by the Indenture Trustee thereof
      and, with respect to any documents received after the Closing Date, promptly
      thereafter), the Indenture Trustee shall, for the benefit of the Noteholders,
      review each Mortgage File delivered to it and to execute and deliver, or cause
      to be executed and delivered, to the Sponsor and the Servicer, an Initial
      Certification in the form annexed hereto as Exhibit H. In conducting such
      review, the Indenture Trustee shall ascertain whether all required documents
      described in Section 2.1(b)(i) to (v) (except clause (v)(ii)) of the Mortgage
      Loan Purchase Agreement, with respect to the Mortgage Loans, have been executed
      and received and whether those documents relate, to the Mortgage Loans it has
      received, as identified in Exhibit B to this Indenture, as supplemented
      (provided,
      however,
      that
      with respect to those documents described in subclause (b)(vi) of such section,
      the Indenture Trustee’s obligations shall extend only to documents actually
      delivered pursuant to such subclause). In performing any such review, the
      Indenture Trustee may conclusively rely on the purported due execution and
      genuineness of any such document and on the purported genuineness of any
      signature thereon. If the Indenture Trustee finds any document constituting
      part
      of the Mortgage File not to have been executed or received, or to be unrelated
      to the Mortgage Loans identified in Exhibit B to this Indenture or to not
      conform with the review criteria set forth in Exhibit H (a “defect”), the
      Indenture Trustee shall promptly notify the Sponsor of such finding and the
      Sponsor’s obligation to cure such defect or repurchase or substitute for the
      related Mortgage Loan. To the extent the Indenture Trustee has not received
      a
      Mortgage File with respect to any of the Mortgage Loans by the Closing Date,
      the
      Indenture Trustee shall not require the deposit of cash into the Payment Account
      or any other account to cover the amount of that Mortgage Loan and shall solely
      treat such Mortgage Loan as if it were in breach of a representation or
      warranty; provided that the aggregate Stated Principal Balance of such Mortgage
      Loans does not exceed 1% of the (i) sum of the Cut-off Date Balances of the
      Mortgage Loans.

     

    (i)  No
      later
      than 180 days after the Closing Date (with respect to the Mortgage Loans),
      the
      Indenture Trustee will review, for the benefit of the Noteholders, the Mortgage
      Files and will execute and deliver or cause to be executed and delivered to
      the
      Sponsor and the Servicer, a Final Certification in the form annexed hereto
      as
      Exhibit I. In conducting such review, Indenture Trustee will ascertain whether
      an original of each document described in subclauses (b)(ii)-(iv) of Section
      2.1
      of the Mortgage Loan Purchase Agreement, with respect to the Mortgage Loans,
      required to be recorded has been returned from the applicable recording office
      with evidence of recording thereon or a certified copy has been obtained from
      such recording office. If the Indenture Trustee finds any document constituting
      part of the Mortgage File has not been executed or received, or to be unrelated,
      to the Mortgage Loans identified in Exhibit B to this Indenture or to appear
      defective on its face, the Indenture Trustee shall promptly notify the
      Sponsor.

     

    (ii)  Upon
      deposit by the Sponsor of the Repurchase Price in the Payment Account, the
      Indenture Trustee shall release to the Sponsor or the Servicer, the related
      Mortgage File and the Indenture Trustee shall execute and deliver all
      instruments of transfer or assignment, without recourse, representation or
      warranty, furnished to it by the Sponsor or the Servicer, as are necessary
      to
      vest in the Sponsor or the Servicer, title to and rights under the related
      Mortgage Loan. Such purchase shall be deemed to have occurred on the date on
      which the deposit of the Repurchase Price in the Payment Account was received
      by
      the Indenture Trustee. The Indenture Trustee shall amend the Mortgage Loan
      Schedule to reflect such repurchase and shall promptly notify the Master
      Servicer, the Servicer and
      the
      Securities Administrator of such amendment.

     

    Section
      2.04  Acceptance
      of Cap Contracts and Corridor Contract by Indenture Trustee.
      The
      Indenture Trustee acknowledges receipt of the Cap Contract and the Corridor
      Contract and declares that it holds and will continue to hold these documents
      and any amendments, replacements or supplements thereto and all other assets
      of
      the Trust Estate as Indenture Trustee in trust for the use and benefit of all
      present and future Holders of the Notes. The Indenture Trustee shall enforce
      the
      Cap Contract and the Corridor Contract in accordance with their
      terms.

      of conditions set forth herein, Notes may be surrendered for registration of
      transfer or exchange, and where notices and demands to or upon the Issuing
      Entity in respect of the Notes and this Indenture may be served. The Issuing
      Entity hereby initially appoints the Indenture Trustee to serve as its agent
      for
      the foregoing purposes. If at any time the Issuing Entity shall fail to maintain
      any such office or agency or shall fail to furnish the Indenture Trustee with

      provided in Section 3.01, all payments of amounts due and payable with respect
      to any Notes that are to be made from amounts withdrawn from the Payment Account
      pursuant to Section 3.01 shall be made on behalf of the Issuing Entity by the
      Indenture Trustee or by the Paying Agent, and no amounts so withdrawn from
      the
      Payment Account for payments of Notes shall be paid over to the Issuing Entity
      except as provided in this Section 3.03. The Issuing Entity hereby appoints
      the
      Indenture Trustee as its Paying Agent.

     

    The
      Issuing Entity will cause each Paying Agent other than the Indenture Trustee
      to
      execute and deliver to the Indenture Trustee an instrument in which such Paying
      Agent shall agree with the Indenture Trustee (and if the Indenture Trustee
      acts
      as Paying Agent it hereby so agrees), subject to the provisions of this Section
      3.03, that such Paying Agent will:

     

    (a)  hold
      all
      sums held by it for the payment of amounts due with respect to the Notes in
      trust for the benefit of the Persons entitled thereto until such sums shall
      be
      paid to such Persons or otherwise disposed of as herein provided and pay such
      sums to such Persons as herein provided;

     

    (b)  give
      the
      Indenture Trustee notice of any default by the Issuing Entity of which it has
      actual knowledge in the making of any payment required to be made with respect
      to the Notes;

     

    (c)  at
      any
      time during the continuance of any such default, upon the written request of
      the
      Indenture Trustee, forthwith pay to the Indenture Trustee all sums so held
      in
      trust by such Paying Agent;

     

    (d)  immediately
      resign as Paying Agent and forthwith pay to the Indenture Trustee all sums
      held
      by it in trust for the payment of Notes if at any time it ceases to meet the
      standards required to be met by a Paying Agent at the time of its
      appointment;

     

    (e)  comply
      with all requirements of the Code with respect to the withholding from any

    (f)  not
      commence a bankruptcy proceeding against the Issuing Entity in connection with
      this Indenture.

     

    The
      Issuing Entity may at any time, for the purpose of obtaining the satisfaction
      and discharge of this Indenture or for any other purpose, by Issuing Entity
      Request direct any Paying Agent to pay to the Indenture Trustee all sums held
      in
      trust by such Paying Agent, such sums to be held by the Indenture Trustee upon
      the same trusts as those upon which the sums were held by such Paying Agent;
      and
      upon such payment by any Paying Agent to the Indenture Trustee, such Paying
      Agent shall be released from all further liability with respect to such
      money.

     

    Subject
      to applicable laws with respect to escheat of funds, any money held by the
      Indenture Trustee or any Paying Agent in trust for the payment of any amount
      due
      with respect to any Note and remaining unclaimed for one year after such amount
      has become due and payable shall be discharged from such trust and be paid
      to
      the Issuing Entity; and the Holder of such Note shall thereafter, as an
      unsecured general creditor, look only to the Issuing Entity for payment thereof
      (but only to the extent of the amounts so paid to the Issuing Entity), and
      all
      liability of the Indenture Trustee or such Paying Agent with respect to such
      trust money shall thereupon cease; provided,
      however,
      that the
      Indenture Trustee or such Paying Agent, before being required to make any such
      repayment, shall at the expense and direction of the Issuing Entity cause to
      be
      published once, in an Authorized Newspaper published in the English language,
      notice that such money remains unclaimed and that, after a date specified
      therein which shall not be less than 30 days from the date of such publication,
      any unclaimed balance of such money then remaining will be repaid to the Issuing
      Entity. The Indenture Trustee may also adopt and employ, at the expense and
      direction of the Issuing Entity, any other reasonable means of notification
      of
      such repayment (including, but not limited to, mailing notice of such repayment
      to Holders whose Notes have been called but have not been surrendered for
      redemption or whose right to or interest in monies due and payable but not
      claimed is determinable from the records of the Indenture Trustee or of any
      Paying Agent, at the last address of record for each such Holder).

     

    Section
      3.04  Existence.
      The
      Issuing Entity will keep in full effect its existence, rights and franchises
      as
      a statutory trust under the laws of the State of Delaware (unless it becomes,
      or
      any successor Issuing Entity hereunder is or becomes, organized under the laws
      of any other state or of the United States of America, in which case the Issuing
      Entity will keep in full effect its existence, rights and franchises under
      the
      laws of such other jurisdiction) and will obtain and preserve its qualification
      to do business in each jurisdiction in which such qualification is or shall

      the
      Note Principal Balances thereof, until the aggregate Note Principal Balance
      of
      the Group II-C Senior Notes or Group II-NC Senior Notes, as applicable, is
      equal
      to the aggregate Stated Principal Balance of the Mortgage Loans in its related

      II-M Notes or Class II-B Notes on such Payment Date will be reduced, if
      necessary, and distributed to such Class or Classes of Group II-C Senior Notes
      or Group II-NC Senior Notes, as applicable, in an amount equal to the Accrued
      Note Interest for such Payment Date on the excess of (x) the aggregate Note
      Principal Balance of the Group II-C Senior Notes or Group II-NC Senior Notes,
      as
      applicable, over (y) the aggregate Stated Principal Balance of the Mortgage
      Loans in the related Loan Group. Any such reduction in the Accrued Note Interest
      on the Class II-M Notes and Class II-B Notes shall be allocated first to the
      Class II-B Notes and second, in reverse order of the Class II-M Notes’ numerical
      designations, commencing with the Class II-M-5 Notes.

     

    On
      each
      Payment Date, any Group II-C Available Funds or Group II-NC Available Funds
      remaining after payment of interest and principal to the Classes of Notes
      entitled thereto, as described above, shall be distributed to the Certificate
      Paying Agent, as designee of the Issuing Entity, for the benefit of the Holders

      of
      the representations and warranties made by the Sponsor in the Mortgage Loan
      Purchase Agreement concerning the Sponsor and the Mortgage Loans to the same
      extent as though such representations and warranties were made directly to
      the
      Indenture Trustee. If a Responsible Officer of the Indenture Trustee has actual
      knowledge of any breach of any representation or warranty made by the Sponsor
      in
      the Mortgage Loan Purchase Agreement, the Indenture Trustee shall promptly
      notify the Sponsor of such finding and of the Sponsor’s obligation to cure such

      for purposes of perfection under Section 9-305 of the Uniform Commercial Code
      or
      other similar applicable law, rule or regulation of the state in which such
      property is held by the Servicer, the Issuing Entity and the Indenture Trustee
      hereby acknowledge that the Servicer is acting as bailee of the Indenture
      Trustee in holding amounts on deposit in the related Collection Account and
      the
      related Protected Account, as well as its bailee in holding any Related
      Documents released to the Servicer, and any other items constituting a part
      of
      the Trust Estate which from time to time come into the possession of the
      Servicer. It is intended that, by the Servicer’s acceptance of such bailee
      arrangement, the Indenture Trustee, as a secured party of the Mortgage Loans
      will be deemed to have possession of such Related Documents, such monies and
      such other items for purposes of Section 9-305 of the Uniform Commercial Code
      of
      the state in which such property is held by the Servicer. The Indenture Trustee
      shall not be liable with respect to such documents, monies or items while in
      possession of the Servicer.

      the rules and regulations thereunder (taking into account not only the general
      definition of the term “investment company” but also any available exceptions to
      such general definition); provided,
      however,
      that the
      Issuing Entity shall be in compliance with this Section 3.19 if it shall have
      obtained an order exempting it from regulation as an “investment company” so
      long as it is in compliance with the conditions imposed in such

      Indenture, the Issuing Entity has not pledged, assigned, sold, granted a
      security interest in, or otherwise conveyed any of the Collateral.

     

    (c)  With
      respect to any Collateral in which a security interest may be perfected by
      filing, the Issuing Entity has not authorized the filing of, and is not aware
      of
      any financing statements against, the Issuing Entity, that include a description
      of collateral covering such Collateral, other than any financing statement
      relating to the security interest granted to the Indenture Trustee hereunder
      or
      that has been terminated. The Issuing Entity is not aware of any judgment or
      tax
      lien filings against the Issuing Entity.

     

    (d)  The
      Issuing Entity has caused or will have caused, within ten days of the Closing
      Date, the filing of all appropriate financing statements in the proper filing
      office in the appropriate jurisdictions under applicable law in order to perfect
      the security interest in all Collateral granted to the Indenture Trustee
      hereunder in which a security interest may be perfected by filing. Any financing
      statement that is filed in connection with this Section 3.37 shall contain
      a
      statement that a purchase or security interest in any collateral described
      therein will violate the rights of the secured party named in such financing
      statement.

     

    (e)  The
      foregoing representations may not be waived and shall survive the issuance
      of
      the Notes.

    THE
      NOTES; SATISFACTION AND DISCHARGE OF INDENTURE

     

    Section
      4.01  The
      Notes.
      Each
      Class of Offered Notes shall be registered in the name of a nominee designated
      by the Depository. With respect to the Offered Notes, Beneficial Owners will
      hold interests in such Notes through the book-entry facilities of the Depository
      in minimum initial Note Principal Balances of $100,000 and integral multiples
      of
      $1 in excess thereof. The Non-Offered Notes will be issued in fully registered
      definitive physical form in minimum dollar denominations of $25,000 and integral
      multiples of $1 in excess thereof.

     

    The
      Indenture Trustee may for all purposes (including the making of payments due
      on
      the Notes) deal with the Depository as the authorized representative of the
      Beneficial Owners with respect to the Offered
      Notes
      for
      the purposes of exercising the rights of Holders of the Notes hereunder. Except
      as provided in the next succeeding paragraph of this Section 4.01, the rights
      of
      Beneficial Owners with respect to the Offered Notes shall be limited to those
      established by law and agreements between such Beneficial Owners and the
      Depository and Depository Participants. Except as provided in Section 4.08
      hereof, Beneficial Owners shall not be entitled to definitive certificates
      for
      the Offered Notes as to which they are the Beneficial Owners. Requests and
      directions from, and votes of, the Depository as Holder of the Offered Notes
      shall not be deemed inconsistent if they are made with respect to different
      Beneficial Owners. The Indenture Trustee may establish a reasonable record
      date
      in connection with solicitations of consents from or voting by Noteholders
      and
      give notice to the Depository of such record date. Without the consent of the
      Issuing Entity and the Indenture Trustee, no Offered Note may be transferred
      by
      the Depository except to a successor Depository that agrees to hold such Note
      for the account of the Beneficial Owners.

     

    In
      the
      event the Depository Trust Company resigns or is removed as Depository, the
      Indenture Trustee with the approval of the Issuing Entity may appoint a
      successor Depository. If no successor Depository has been appointed within
      30
      days of the effective date of the Depository’s resignation or removal, each
      Beneficial Owner shall be entitled to certificates representing the Offered
      Notes it beneficially owns in the manner prescribed in Section
      4.08.

     

    The
      Notes
      shall, on original issue, be executed on behalf of the Issuing Entity by the
      Owner Trustee, not in its individual capacity but solely as Owner Trustee,
      authenticated by the Indenture Trustee and delivered by the Indenture Trustee
      to
      or upon an Issuing Entity Request.

     

    Section
      4.02  Registration
      of and Limitations on Transfer and Exchange of Notes; Appointment of Note
      Registrar and Certificate Registrar.

     

    (a)  The
      Issuing Entity shall cause to be kept at the Corporate Trust Office of the
      Note
      Registrar a Note Register in which, subject to such reasonable regulations
      as it
      may prescribe, the Note Registrar shall provide for the registration of Notes
      and of transfers and exchanges of Notes as herein provided.

     

    Subject
      to the restrictions and limitations set forth below, upon surrender for
      registration of transfer of any Note at
      the
office
      designated by
      the
Indenture
      Trustee,
      the
      Issuing Entity shall execute and the Note Registrar shall authenticate and
      deliver, in the name of the designated transferee or transferees, one or more
      new Notes in authorized initial Note Principal Balances evidencing the same
      Class and aggregate Percentage Interests.

     

    Subject
      to the foregoing, at the option of the Noteholders, Notes may be exchanged
      for
      other Notes of like tenor and in authorized initial Note Principal Balances
      evidencing the same Class and aggregate Percentage Interests upon surrender
      of
      the Notes to be exchanged at the office designated by the Note Registrar.
      Whenever any Notes are so surrendered for exchange, the Issuing Entity shall
      execute and the Indenture Trustee shall authenticate and deliver the Notes
      which
      the Noteholder making the exchange is entitled to receive. Each Note presented
      or surrendered for registration of transfer or exchange shall (if so required
      by
      the Note Registrar) be duly endorsed by, or be accompanied by a written
      instrument of transfer in form reasonably satisfactory to the Note Registrar
      duly executed by the Holder thereof or his attorney duly authorized in writing
      with such signature guaranteed by a commercial bank or trust company located
      or
      having a correspondent located in the city of New York. Notes delivered upon
      any
      such transfer or exchange will evidence the same obligations, and will be
      entitled to the same rights and privileges, as the Notes
      surrendered.

     

    No
      service charge shall be made for any registration of transfer or exchange of
      Notes, but the Note Registrar shall require payment of a sum sufficient to
      cover
      any tax or governmental charge that may be imposed in connection with any
      registration of transfer or exchange of Notes.

     

    The
      Issuing Entity hereby appoints the Indenture Trustee as (i) Certificate
      Registrar to keep at its Corporate Trust Office a Certificate Register pursuant
      to Section 3.09 of the Trust Agreement in which, subject to such reasonable
      regulations as it may prescribe, the Certificate Registrar shall provide for
      the
      registration of Certificates and of transfers and exchanges thereof pursuant
      to
      Section 3.05 of the Trust Agreement and (ii) Note Registrar under this
      Indenture. The Indenture Trustee hereby accepts such appointments.

     

    (b)  No
      Person
      shall become a Holder of Non-Offered Notes until it shall establish its
      non-foreign status by submitting to the Paying Agent an IRS Form W-9 and the
      Certificate of Non-Foreign Status set forth in Exhibit L hereto.

     

    No
      transfer, sale, pledge or other disposition of a Non-Offered Note shall be
      made
      unless such transfer, sale, pledge or other disposition is exempt from the
      registration requirements of the Securities Act and any applicable state
      securities laws or is made in accordance with said Act and laws. In the event
      of
      any such transfer, the Note Registrar or the Depositor shall prior to such
      transfer require the transferee to execute (A) either (i) (a) an investment
      letter in substantially the form attached hereto as Exhibit K (or in such form
      and substance reasonably satisfactory to the Note Registrar and the Depositor)
      which investment letter shall not be an expense of the Trust, the Owner Trustee,
      the Indenture Trustee, the Securities Administrator, the Note Registrar, the
      Master Servicer, the Servicer, the Sponsor or the Depositor and which investment
      letter states that, among other things, such transferee (1) is a “qualified
      institutional buyer” as defined under Rule 144A, acting for its own account or
      the accounts of other “qualified institutional buyers” as defined under Rule
      144A, and (2) is aware that the proposed transferor intends to rely on the
      exemption from registration requirements under the Securities Act of 1933,
      as
      amended, provided by Rule 144A or (ii) (a) a written Opinion of Counsel
      acceptable to and in form and substance satisfactory to the Note Registrar
      and
      the Depositor that such transfer may be made pursuant to an exemption,
      describing the applicable exemption and the basis therefor, from said Act and
      laws or is being made pursuant to said Act and laws, which Opinion of Counsel
      shall not be an expense of the Trust, the Owner Trustee, the Indenture Trustee,
      the Securities Administrator, the Note Registrar, the Master Servicer, the
      Servicer, the Sponsor or the Depositor and (b) either (1) the transferee
      executes a representation letter, substantially in the form of Exhibit M hereto,
      and the transferor executes a representation letter, substantially in the form
      of Exhibit N hereto, each acceptable to and in form and substance satisfactory
      to the Note Registrar certifying the facts surrounding such transfer, which
      representation letters shall not be an expense of the Trust, the Owner Trustee,
      the Indenture Trustee, the Securities Administrator, the Note Registrar, the
      Master Servicer, the Servicer, the Sponsor or the Depositor or (2) an
      Opinion of Counsel has been rendered by nationally recognized tax counsel
      stating that such Notes will be treated as debt for federal income tax
      purposes
      and (B)
      the Certificate of Non-Foreign Status (in substantially the form attached hereto
      as Exhibit L) acceptable to and in form and substance reasonably satisfactory
      to
      the Note Registrar, which certificate shall not be an expense of the Trust,
      the
      Owner Trustee, the Indenture Trustee, the Securities Administrator, the Note
      Registrar, the Master Servicer, the Servicer, the Sponsor or the Depositor.
      The
      Holder of a Non-Offered Note desiring to effect such transfer shall, and does
      hereby agree to, indemnify the Trust, the Owner Trustee, the Indenture Trustee,
      the Paying Agent, the Note Registrar, the Master Servicer, the Servicer 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.

     

    No
      person
      shall become a Holder of Non-Offered Notes, so long as any Notes are
      Outstanding, until it shall establish its status as a real estate investment
      trust (“REIT”) or as a “qualified REIT subsidiary” (“QRS”) within the meaning of
      Section 856(a) or Section 856(i) of the Code, respectively, by submitting to
      the
      Note Registrar and the Transferee Certificate set forth in Exhibit P hereto
      and,
      following such transfer, such Holder of Non-Offered Notes shall own 100% of
      the
      Non-Offered Notes and the Trust Certificates.

     

    No
      offer,
      sale, transfer, pledge, hypothecation or other disposition (including any
      pledge, sale or transfer under a repurchase transaction or securities loan)
      of
      any Non-Offered Note shall be made to any transferee unless, prior to such
      disposition, the proposed transferor delivers to the Note Registrar (i) an
      Opinion of Counsel, rendered by a law firm generally recognized to be qualified
      to opine concerning the tax aspects of asset securitization, to the effect
      that
      such transfer (including any disposition permitted following any default under
      any pledge or repurchase transaction) will not cause the Trust to be no longer
      be treated for federal income tax purposes as a “qualified REIT subsidiary”
within the meaning of Section 856(i) of the Code and (ii) a certificate that
      stating that any Non-Offered Notes may be transferred by the related lender
      under any such related loan agreement or repurchase agreement upon a default
      under any such indebtedness, in which case the transferor shall deliver to
      the
      Note Registrar and the Indenture Trustee substantially in the form attached
      hereto as Exhibit Q certifying to such effect. Notwithstanding the foregoing,
      the provisions of this paragraph shall not apply to the initial transfer of
      the
      Non-Offered Notes to the Depositor.

     

    No
      offer,
      sale, transfer or other disposition (including pledge) of any Non-Offered Note
      shall be made to any affiliate of the Depositor or the Issuing Entity, other
      than the initial transfer of the Non-Offered Notes to the
      Depositor.

     

    With
      respect to the restriction on transfer of the Notes contained in this Section
      4.02 and in Section 4.15, any transferor providing an Opinion of Counsel shall
      (i) deliver such opinion to the appropriate addressees, (ii) confirm the
      acceptability of such opinion with the applicable addressees and (iii) inform
      the Note Registrar of delivery and confirmation described in clause (i) and
      clause (ii).

     

    Section
      4.03  Mutilated,
      Destroyed, Lost or Stolen Notes.
      If (i)
      any mutilated Note is surrendered to the Indenture Trustee, or the Indenture
      Trustee receives evidence to its satisfaction of the destruction, loss or theft
      of any Note, and (ii) there is delivered to the Indenture Trustee such security
      or indemnity as may be required by it to hold the Issuing Entity and the
      Indenture Trustee harmless, then, in the absence of notice to the Issuing
      Entity, the Note Registrar or the Indenture Trustee that such Note has been
      acquired by a bona fide purchaser, and provided that the requirements of Section
      8-405 of the UCC are met, the Issuing Entity shall execute, and upon Issuing
      Entity Request the Indenture Trustee shall authenticate and deliver, in exchange
      for or in lieu of any such mutilated, destroyed, lost or stolen Note, a
      replacement Note; provided,
      however,
      that if
      any such destroyed, lost or stolen Note, but not a mutilated Note, shall have
      become or within seven days shall be due and payable, instead of issuing a
      replacement Note, the Issuing Entity may pay such destroyed, lost or stolen
      Note
      when so due or payable without surrender thereof. If, after the delivery of
      such
      replacement Note or payment of a destroyed, lost or stolen Note pursuant to
      the
      proviso to the preceding sentence, a bona fide purchaser of the original Note
      in
      lieu of which such replacement Note was issued presents for payment such
      original Note, the Issuing Entity and the Indenture Trustee shall be entitled
      to
      recover such replacement Note (or such payment) from the Person to whom it
      was
      delivered or any Person taking such replacement Note from such Person to whom
      such replacement Note was delivered or any assignee of such Person, except
      a
      bona fide purchaser, and shall be entitled to recover upon the security or
      indemnity provided therefor to the extent of any loss, damage, cost or expense
      incurred by the Issuing Entity or the Indenture Trustee in connection
      therewith.

     

    Upon
      the
      issuance of any replacement Note under this Section 4.03, the Issuing Entity
      may
      require the payment by the Holder of such Note of a sum sufficient to cover
      any
      tax or other governmental charge that may be imposed in relation thereto and
      any
      other reasonable expenses (including the fees and expenses of the Indenture
      Trustee) connected therewith.

     

    Every
      replacement Note issued pursuant to this Section 4.03 in replacement of any
      mutilated, destroyed, lost or stolen Note shall constitute an original
      additional contractual obligation of the Issuing Entity, whether or not the
      mutilated, destroyed, lost or stolen Note shall be at any time enforceable
      by
      anyone, and shall be entitled to all the benefits of this Indenture equally
      and
      proportionately with any and all other Notes duly issued hereunder.

     

    The
      provisions of this Section 4.03 are exclusive and shall preclude (to the extent
      lawful) all other rights and remedies with respect to the replacement or payment
      of mutilated, destroyed, lost or stolen Notes.

     

    Section
      4.04  Persons
      Deemed Owners.
      Prior
      to due presentment for registration of transfer of any Note, the Issuing Entity,
      the Indenture Trustee, the Paying Agent and any agent of the Issuing Entity
      or
      the Indenture Trustee or the Paying Agent may treat the Person in whose name
      any
      Note is registered (as of the day of determination) as the owner of such Note
      for the purpose of receiving payments of principal of and interest, if any,
      on
      such Note and for all other purposes whatsoever, whether or not such Note be
      overdue, and neither the Issuing Entity, the Indenture Trustee, the Paying
      Agent
      nor any agent of the Issuing Entity or the Indenture Trustee or the Paying
      Agent
      shall be affected by notice to the contrary.

     

    Section
      4.05  Cancellation.
      All
      Notes surrendered for payment, registration of transfer, exchange or redemption
      shall, if surrendered to any Person other than the Indenture Trustee, be
      delivered to the Indenture Trustee and shall be promptly cancelled by the
      Indenture Trustee. The Issuing Entity may at any time deliver to the Indenture
      Trustee for cancellation any Notes previously authenticated and delivered
      hereunder which the Issuing Entity may have acquired in any manner whatsoever,
      and all Notes so delivered shall be promptly cancelled by the Indenture Trustee.
      No Notes shall be authenticated in lieu of or in exchange for any Notes
      cancelled as provided in this Section 4.05, except as expressly permitted by
      this Indenture. All cancelled Notes may be held or disposed of by the Indenture
      Trustee in accordance with its standard retention or disposal policy as in
      effect at the time unless the Issuing Entity shall direct by an Issuing Entity
      Request that they be destroyed or returned to it; provided,
      however,
      that
      such Issuing Entity Request is timely and the Notes have not been previously
      disposed of by the Indenture Trustee.

     

    Section
      4.06  Book-Entry
      Notes.
      The
Offered
      Notes,
      upon original issuance, will be issued in the form of typewritten Notes
      representing the Book-Entry Notes, to be delivered to The Depository Trust
      Company, the initial Depository, or its designated custodian, by, or on behalf
      of, the Issuing Entity. The Offered Notes shall initially be registered on
      the
      Note Register in the name of Cede & Co., the nominee of the initial
      Depository, and no Beneficial Owner will receive a Definitive Note representing
      such Beneficial Owner’s interest in such Note, except as provided in Section
      4.08. With respect to such Notes, unless and until definitive, fully registered
      Notes (the “Definitive Notes”) have been issued to Beneficial Owners pursuant to
      Section 4.08:

     

    (i)  the
      provisions of this Section 4.06 shall be in full force and effect;

     

    (ii)  the
      Note
      Registrar, the Paying Agent and the Indenture Trustee shall be entitled to
      deal
      with the Depository for all purposes of this Indenture (including the payment
      of
      principal of and interest on the Notes and the giving of instructions or
      directions hereunder) as the sole Holder of the Notes, and shall have no
      obligation to the Beneficial Owners of the Notes;

     

    (iii)  to
      the
      extent that the provisions of this Section 4.06 conflict with any other
      provisions of this Indenture, the provisions of this Section 4.06 shall
      control;

     

    (iv)  the
      rights of Beneficial Owners shall be exercised only through the Depository
      and
      shall be limited to those established by law and agreements between such Owners
      of Notes and the Depository and/or the Depository Participants. Unless and
      until
      Definitive Notes are issued pursuant to Section 4.08, the initial Depository
      will make book-entry transfers among the Depository Participants and receive
      and
      transmit payments of principal of and interest on the Notes to such Depository
      Participants; and

     

    (v)  whenever
      this Indenture requires or permits actions to be taken based upon instructions
      or directions of Holders of Notes evidencing a specified percentage of the
      Note
      Principal Balances of the Notes, the Depository shall be deemed to represent
      such percentage with respect to the Notes only to the extent that it has
      received instructions to such effect from Beneficial Owners and/or Depository
      Participants owning or representing, respectively, such required percentage
      of
      the beneficial interest in the Notes and has delivered such instructions to
      the
      Indenture Trustee.

     

    Section
      4.07  Notices
      to Depository.
      Whenever a notice or other communication to the Noteholders is required under
      this Indenture, unless and until Definitive Notes shall have been issued to
      Beneficial Owners pursuant to Section 4.08, the Indenture Trustee shall give
      all
      such notices and communications specified herein to be given to Holders of
      the
      Offered Notes to the Depository, and shall have no obligation to the Beneficial
      Owners.

     

    Section
      4.08  Definitive
      Notes.
      If (i)
      the Depositor advises the Indenture Trustee or the Note Registrar in writing
      that the Depository is no longer willing or able to properly discharge its
      responsibilities as clearing agency with respect to the Offered Notes and the
      Depositor is unable to locate a qualified successor within 30 days, (ii) the
      Depositor, at its option (with the consent of the Indenture Trustee, which
      consent shall not by unreasonably withheld), elects to terminate the book-entry
      system through the Depository or (iii) after the occurrence of an Event of
      Default, any Note Owner materially and adversely affected thereby may, at its
      option, request and receive a Definitive Note evidencing such Note Owner’s
      Percentage Interest in the related Class of Offered Notes. Upon surrender to
      the
      Indenture Trustee of the global Offered Note or definitive typewritten Notes
      representing the Book-Entry Notes by the Depository, accompanied by registration
      instructions, the Note Registrar will re-issue the Book-Entry Notes as
      Definitive Notes issued in the respective Note Principal Balances owned by
      individual Note Owners. None of the Issuing Entity, the Note Registrar or the
      Indenture Trustee shall be liable for any delay in delivery of such instructions
      and may conclusively rely on, and shall be protected in relying on, such
      instructions. Upon the issuance of Definitive Notes, the Indenture Trustee
      shall
      recognize the Holders of the Definitive Notes as Noteholders.

     

    Section
      4.09  Tax
      Treatment.
      The
      Issuing Entity has entered into this Indenture, and the Notes will be issued
      with the intention that, for federal, state and local income, single business
      and franchise tax purposes, the Notes (other than the Non-Offered Notes, which
      at the time of issuance, American Home Mortgage Investment Corp. or one of
      its
      qualified REIT subsidiaries acquires beneficial ownership thereof)will qualify
      as indebtedness. The Issuing Entity and the Indenture Trustee (in accordance
      with Section 6.06 hereof), by entering into this Indenture, and each Noteholder,
      by its acceptance of its Note (and each Beneficial Owner by its acceptance
      of an
      interest in the applicable Book-Entry Note), agree to treat the Notes for
      federal, state and local income, single business and franchise tax purposes
      as
      indebtedness.

     

    Section
      4.10  Satisfaction
      and Discharge of Indenture.
      This
      Indenture shall cease to be of further effect with respect to the Notes except
      as to (i) rights of registration of transfer and exchange, (ii) substitution
      of
      mutilated, destroyed, lost or stolen Notes, (iii) rights of Noteholders to
      receive payments of principal thereof and interest thereon, (iv) Sections 3.03
      and 3.05, (v) the rights and immunities of the Indenture Trustee hereunder
      (including the rights of the Indenture Trustee under Section 6.07) and the
      obligations of the Indenture Trustee under Section 4.11 and (vi) the rights
      of
      Noteholders as beneficiaries hereof with respect to the property so deposited
      with the Indenture Trustee payable to all or any of them, and the Indenture
      Trustee, on demand of and at the expense of the Issuing Entity, shall execute
      proper instruments acknowledging satisfaction and discharge of this Indenture
      with respect to the Notes and shall release and deliver the Collateral to or
      upon the Issuing Entity Request, when

     

              
      (A)  either

     

    (1)  all
      Notes
      theretofore authenticated and delivered (other than (i) Notes that have been
      destroyed, lost or stolen and that have been replaced or paid as provided in

      provided in Section 3.03) have been delivered to the Indenture Trustee for
      cancellation; or

     

    (2)  all

    and
      the
      Issuing Entity, in the case of a. or b. above, has irrevocably deposited or
      caused to be irrevocably deposited with the Indenture Trustee cash or direct
      obligations of or obligations guaranteed by the United States of America (which
      will mature prior to the date such amounts are payable), in trust for such
      purpose, in an amount sufficient to pay and discharge the entire indebtedness
      on
      such Notes then outstanding not theretofore delivered to the Indenture Trustee
      for cancellation when due on the Final Scheduled Payment Date or other final
      Payment Date and has delivered to the Indenture Trustee a verification report
      with respect to such direct obligations or obligations guaranteed by the United
      States of America from a nationally recognized accounting firm certifying that
      the amounts deposited with the Indenture Trustee are sufficient to pay and
      discharge the entire indebtedness of such Notes, or, in the case of c. above,
      the Issuing Entity shall have complied with all requirements of Section 8.08
      hereof; and

     

    (B)  the
      Issuing Entity has delivered to the Indenture Trustee, an Officer’s Certificate
      and an Opinion of Counsel, each meeting the applicable requirements of Section
      10.01 hereof, each stating that all conditions precedent herein provided for
      relating to the satisfaction and discharge of this Indenture have been complied
      with and, if the Opinion of Counsel relates to a deposit made in connection
      with
      Section 4.10(A)(2)b. above, such opinion shall further be to the effect that
      such deposit will constitute an “in-substance defeasance” within the meaning of
      Revenue Ruling 85-42, 1985-1 C.B. 36, and in accordance therewith, the Issuing
      Entity will be the owner of the assets deposited in trust for federal income
      tax
      purposes.

     

    Section
      4.11  Application
      of Trust Money.
      All
      monies deposited with the Indenture Trustee pursuant to Section 4.10 hereof
      shall be held in trust and applied by it, in accordance with the provisions
      of
      the Notes and this Indenture, to the payment, either directly or through any

      as the Indenture Trustee may determine, to the Holders of Securities, of all
      sums due and to become due thereon for principal and interest or otherwise;

      applied according to Section 3.05 and thereupon such Person shall be released
      from all further liability with respect to such monies.

     

    Section
      4.14  Temporary
      Notes.
      Pending
      the preparation of any Definitive Notes, the Issuing Entity may execute and
      upon
      its written direction, the Indenture Trustee may authenticate and make available
      for delivery, temporary Notes that are printed, lithographed, typewritten,
      photocopied or otherwise produced, in any denomination, substantially of the
      tenor of the Definitive Notes in lieu of which they are issued and with such
      appropriate insertions, omissions, substitutions and other variations as the
      officers executing such Notes may determine, as evidenced by their execution
      of
      such Notes.

     

    If
      temporary Notes are issued, the Issuing Entity will cause Definitive Notes
      to be
      prepared without unreasonable delay. After the preparation of the Definitive
      Notes, the temporary Notes shall be exchangeable for Definitive Notes upon
      surrender of the temporary Notes at the office of the agent of the Indenture
      Trustee located at c/o DB Services Tennessee, 648 Grassmere Park Road,
      Nashville, Tennessee 37211-3658, without charge to the Holder. Upon surrender
      for cancellation of any one or more temporary Notes, the Issuing Entity shall
      execute and, upon Issuing Entity Request, the Indenture Trustee shall
      authenticate and make available for delivery, in exchange therefor, Definitive
      Notes of authorized denominations and of like tenor, class and aggregate
      principal amount. Until so exchanged, such temporary Notes shall in all respects
      be entitled to the same benefits under this Indenture as Definitive
      Notes.

     

    Section
      4.15  Representation
      Regarding ERISA.
      By
      acquiring an Offered Note or interest therein, each Holder of such Note or
      Beneficial Owner of any such interest will be deemed to represent that either
      (1) it is not acquiring such Note with Plan Assets or (2) (A) the acquisition,
      holding and transfer of such Note will not give rise to a non-exempt prohibited
      transaction under Section 406 of ERISA or Section 4975 of the Code and (B)
      the
      Offered Note is rated investment grade or better and such person believes that
      the Offered Note is properly treated as indebtedness without substantial equity
      features for purposes of Department of Labor regulation 29 C.F.R. § 2510.3-101
      (the “DOL Regulations”), and agrees to so treat the Note. Alternatively,
      regardless of the rating of the Offered Note, such person may provide the
      Indenture Trustee and the Owner Trustee with an opinion of counsel, which
      opinion of counsel will not be at the expense of the Issuing Entity, the
      Sponsor, the Depositor, any Underwriter, the Owner Trustee, the Indenture
      Trustee, the Securities Administrator, the Servicer or any successor servicer
      which opines that the acquisition, holding and transfer of such Offered Note
      or
      interest therein is permissible under applicable law, will not constitute or
      result in a non-exempt prohibited transaction under ERISA or Section 4975 of
      the
      Code and will not subject the Issuing Entity, the Sponsor, the Depositor, any
      Underwriter, the Owner Trustee, the Indenture Trustee, the Servicer, the Master
      Servicer or the Securities Administrator or any successor servicer to any
      obligation in addition to those undertaken in the Indenture.

     

    No
      transfer of Non-Offered Notes or any interest therein shall be made to any
      Person unless the Depositor, the Owner Trustee, the Indenture Trustee, the
      Note
      Registrar and the Servicer are provided with an Opinion of Counsel which
      establishes to the satisfaction of the Note Registrar that the purchase of
      Non-Offered Notes, operation of the Trust and management of Trust assets are
      permissible under applicable law, will not constitute or result in any
      prohibited transaction under ERISA or Section 4975 of the Code and will not
      subject the Depositor, the Owner Trustee, the Note Registrar, the Securities
      Administrator, the Master Servicer, the Sponsor, the Servicer or any successor
      servicer to any obligation or liability (including obligations or liabilities
      under ERISA or Section 4975 of the Code) in addition to those undertaken in
      this
      Agreement, which Opinion of Counsel shall not be an expense of the Depositor,
      the Owner Trustee, the Indenture Trustee, the Note Registrar, the Securities
      Administrator, the Master Servicer, the Servicer or the Sponsor. In lieu of
      such
      Opinion of Counsel, a Person acquiring such Non-Offered Notes may provide a
      certification in the form of Exhibit O hereto to the Depositor, the Owner
      Trustee and the Note Registrar, which the Depositor, the Owner Trustee, the
      Indenture Trustee, the Note Registrar, the Securities Administrator, the Master
      Servicer, the Servicer and the Sponsor may rely upon without further inquiry
      or
      investigation. Neither an Opinion of Counsel nor a certification will be
      required in connection with the initial transfer of any such Non-Offered Note
      by
      the Depositor to an affiliate of the Depositor (in which case, the Depositor
      or
      any affiliate thereof shall be deemed to have represented that such affiliate
      is
      not a Plan or a Person investing Plan Assets of any Plan) and the Owner Trustee
      and the Note Registrar shall be entitled to conclusively rely upon a
      representation (which, upon the request of the Owner Trustee or the Note
      Registrar, shall be a written representation) from the Depositor of the status
      of such transferee as an affiliate of the Depositor.

    DEFAULT
      AND REMEDIES

     

    Section
      5.01  Events
      of Default.
      The
      Issuing Entity shall deliver to the Indenture Trustee, within five days after
      learning of the occurrence of an Event of Default, written notice in the form
      of
      an Officer’s Certificate of any event which with the giving of notice and the
      lapse of time would become an Event of Default under clause (c) or (d) of the
      definition of “Event of Default”, its status and what action the Issuing Entity
      is taking or proposes to take with respect thereto. The Indenture Trustee shall
      not be deemed to have knowledge of any Event of Default unless a Responsible
      Officer has actual knowledge thereof or unless written notice of such Event
      of
      Default is received by a Responsible Officer and such notice references the
      Notes, the Trust Estate or this Indenture.

     

    Section
      5.02  Acceleration
      of Maturity; Rescission and Annulment.
      If an
      Event of Default should occur and be continuing, then and in every such case
      the
      Indenture Trustee (i) with respect to the Notes, at the written direction of
      the
      Holders of Notes representing not less than a majority of the aggregate Note
      Principal Balance of the Notes, and upon any such declaration the unpaid Note
      Principal Balance of the Notes, together with accrued and unpaid interest
      thereon through the date of acceleration, shall become immediately due and
      payable.

     

    At
      any
      time after such declaration of acceleration of maturity with respect to an
      Event
      of Default has been made and before a judgment or decree for payment of the
      money due has been obtained by the Indenture Trustee as hereinafter in this
      Article V provided, (i) with respect to the Notes, the Holders of the Notes
      representing not less than a majority of the aggregate Note Principal Balance
      of
      each Class of Notes, by written notice to the Issuing Entity and the Indenture
      Trustee, may waive the related Event of Default and rescind and annul such
      declaration and its consequences if:

     

    (a)  the
      Issuing Entity has paid or deposited with the Indenture Trustee a sum sufficient
      to pay:

     

    (A)  all
      payments of principal of and interest on the Notes and all other amounts that
      would then be due hereunder or under the Notes if the Event of Default giving
      rise to such acceleration had not occurred;

     

    (B)  all
      sums
      paid or advanced by the Indenture Trustee hereunder and the reasonable
      compensation, expenses, disbursements and advances of the Indenture Trustee
      and
      its agents and counsel; and

     

    (C)  all
      amounts owed to the Cap Counterparty and the Corridor Provider.

     

    (b)  All
      Events of Default, other than the nonpayment of the principal of the Notes
      that
      has become due solely by such acceleration, have been cured or waived as
      provided in Section 5.12.

     

    No
      such
      rescission shall affect any subsequent default or impair any right consequent
      thereto.

     

    Section
      5.03  Collection
      of Indebtedness and Suits for Enforcement by Indenture Trustee.

     

    (a)  The
      Issuing Entity covenants that if (i) default is made in the payment of any
      interest on any Note when the same becomes due and payable, and such default
      continues for a period of five days, or (ii) default is made in the payment
      of
      the principal of or any installment of the principal of any Note when the same
      becomes due and payable, the Issuing Entity shall, upon demand of the Indenture
      Trustee, with respect to the Notes at the written direction of the Holders
      of a
      majority of the aggregate Note Principal Balances of the Notes, pay to the
      Indenture Trustee, the Holders of Notes, the whole amount then due and payable
      on the related Notes for principal and interest, with interest at the applicable
      Note Interest Rate upon the overdue principal, and in addition thereto such
      further amount as shall be sufficient to cover the costs and expenses of
      collection, including the reasonable compensation, expenses, disbursements
      and
      advances of the Indenture Trustee and its agents and counsel.

     

    (b)  In
      case
      the Issuing Entity shall fail forthwith to pay such amounts upon such demand,
      the Indenture Trustee, in its own name and as trustee of an express trust,
      subject to the provisions of Section 4.12 and Section 10.16 hereof, may
      institute a Proceeding for the collection of the sums so due and unpaid, and
      may
      prosecute such Proceeding to judgment or final decree, and may enforce the
      same
      against the Issuing Entity or other obligor upon the Notes and collect in the
      manner provided by law out of the property of the Issuing Entity or other
      obligor upon the Notes, wherever situated, the monies adjudged or decreed to
      be
      payable.

     

    (c)  If
      an
      Event of Default occurs and is continuing, the Indenture Trustee, subject to
      the
      provisions of Section 4.12 and Section 10.16 hereof, may, as more particularly
      provided in Section 5.04 hereof, in its discretion, proceed to protect and
      enforce its rights and the rights of the Noteholders by such appropriate
      Proceedings as directed in writing by the Holders of a majority of the aggregate
      Note Principal Balances of each Class of Notes, to protect and enforce any
      such
      rights, whether for the specific enforcement of any covenant or agreement in
      this Indenture or in aid of the exercise of any power granted herein, or to
      enforce any other proper remedy or legal or equitable right vested in the
      Indenture Trustee by this Indenture or by law.

     

    (d)  In
      case
      there shall be pending, relative to the Issuing Entity or any other obligor
      upon
      the Notes or any Person having or claiming an ownership interest in the Trust
      Estate, Proceedings under Title 11 of the United States Code or any other
      applicable federal or state bankruptcy, insolvency or other similar law, or
      in
      case a receiver, assignee or trustee in bankruptcy or reorganization,
      liquidator, sequestrator or similar official shall have been appointed for
      or
      taken possession of the Issuing Entity or its property or such other obligor
      or
      Person, or in case of any other comparable judicial Proceedings relative to
      the
      Issuing Entity or other obligor upon the Notes, or to the creditors or property
      of the Issuing Entity or such other obligor, the Indenture Trustee, as directed
      in writing by the Holders of a majority of the aggregate Note Principal Balances
      of each Class of Notes, irrespective of whether the principal of any Notes
      shall
      then be due and payable as therein expressed or by declaration or otherwise
      and
      irrespective of whether the Indenture Trustee shall have made any demand
      pursuant to the provisions of this Section, shall be entitled and empowered,
      by
      intervention in such Proceedings or otherwise:

     

    (i)  to

      and prove a claim or claims for the whole amount of principal and interest
      owing
      and unpaid in respect of the Notes and to file such other papers or documents
      as

      Trustee (including any claim for reasonable compensation to the Indenture
      Trustee and each predecessor Indenture Trustee, and their respective agents,
      attorneys and counsel, and for reimbursement of all expenses and liabilities
      incurred, and all advances made, by the Indenture Trustee and each predecessor
      Indenture Trustee, except as a result of negligence, willful misconduct or
      bad
      faith) and of the Noteholders allowed in such Proceedings;

     

    (ii)  unless
      prohibited by applicable law and regulations, to vote on behalf of the Holders
      of Notes in any election of a trustee, a standby trustee or Person performing
      similar functions in any such Proceedings;

      any
      such claims and to distribute all amounts received with respect to the claims
      of
      the Noteholders and of the Indenture Trustee on their behalf, and

     

    (iv)  to
      file
      such proofs of claim and other papers or documents as may be necessary or
      advisable in order to have the claims of the Indenture Trustee or the Holders
      of
      Notes allowed in any judicial proceedings relative to the Issuing Entity, its
      creditors and its property;

     

    and
      any
      trustee, receiver, liquidator, custodian or other similar official in any such
      Proceeding is hereby authorized by each of such Noteholders to make payments
      to
      the Indenture Trustee, and, in the event that the Indenture Trustee shall
      consent to the making of payments directly to such Noteholders, to pay to the
      Indenture Trustee such amounts as shall be sufficient to cover reasonable
      compensation to the Indenture Trustee, each predecessor Indenture Trustee and
      their respective agents, attorneys and counsel, and all other expenses and
      liabilities incurred, and all advances made, by the Indenture Trustee and each
      predecessor Indenture Trustee.

     

    (e)  Nothing
      herein contained shall be deemed to authorize the Indenture Trustee to authorize
      or consent to or vote for or accept or adopt on behalf of any Noteholder any
      plan of reorganization, arrangement, adjustment or composition affecting the
      Notes or the rights of any Holder thereof or to authorize the Indenture Trustee
      to vote in respect of the claim of any Noteholder in any such proceeding except,
      as aforesaid, to vote for the election of a trustee in bankruptcy or similar
      Person.

     

    (f)  All
      rights of action and of asserting claims under this Indenture, or under any
      of
      the Notes, may be enforced by the Indenture Trustee without the possession
      of
      any of the Notes or the production thereof in any trial or other Proceedings
      relative thereto, and any such action or proceedings instituted by the Indenture
      Trustee shall be brought in its own name as trustee of an express trust, and
      any
      recovery of judgment, subject to the payment of the expenses, disbursements
      and
      compensation of the Indenture Trustee, each predecessor Indenture Trustee and
      their respective agents and attorneys, shall be for the ratable benefit of
      the
      Holders of the Notes, subject to Section 5.05 hereof.

     

    (g)  In
      any
      Proceedings brought by the Indenture Trustee (and also any Proceedings involving
      the interpretation of any provision of this Indenture to which the Indenture
      Trustee shall be a party), the Indenture Trustee shall be held to represent
      all
      the Holders of the Notes, and it shall not be necessary to make any Noteholder
      a
      party to any such Proceedings.

     

    (h)  When
      the
      Indenture Trustee incurs expenses or renders services in connection with an
      Event of Default specified in clause (e) of the definition thereof or any other
      related Proceedings the expenses (including the reasonable charges and expenses
      of its counsel) and the compensation for the services are intended to constitute
      expenses of administration under any applicable Federal or state bankruptcy,
      insolvency or other similar law.

     

    Section
      5.04  Remedies;
      Priorities.

     

    (a)  If
      an
      Event of Default shall have occurred and be continuing and if an acceleration
      has been declared and not rescinded pursuant to Section 5.02 hereof, the
      Indenture Trustee, subject to the provisions of Section 10.16 hereof, may and
      shall, with respect to the Notes, at
      the
      written direction of the Holders of a majority of the aggregate Note Principal
      Balances of the Notes,
      do one
      or more of the following (subject to Section 5.05 hereof):

     

    (i)  institute
      Proceedings in its own name and as trustee of an express trust for the
      collection of all amounts then payable on the Notes or under this Indenture
      with
      respect thereto, whether by declaration or otherwise, enforce any judgment
      obtained, and collect from the Issuing Entity and any other obligor upon such
      Notes monies adjudged due;

     

    (ii)  institute
      Proceedings from time to time for the complete or partial foreclosure of this
      Indenture with respect to the Trust Estate;

     

    (iii)  exercise
      any remedies of a secured party under the UCC and take any other appropriate
      action to protect and enforce the rights and remedies of the Indenture Trustee
      and the Holders of the Notes; and

     

    (iv)  sell
      the
      Trust Estate or any portion thereof or rights or interest therein, at one or
      more public or private sales called and conducted in any manner permitted by
      law;

     

    provided,
      however,
      that
      the Indenture Trustee may not sell or otherwise liquidate the Trust Estate
      following an Event of Default, unless (A) the Indenture Trustee receives the
      consent of the Holders of 100% of the aggregate Note Principal Balance of the
      Notes then outstanding, (B) it is determined that the proceeds of such sale
      or
      liquidation distributable to the Holders of the Notes are sufficient to
      discharge in full all amounts then due and unpaid upon such Notes for principal
      and interest or (C) it is determined that the mortgage loans will not continue
      to provide sufficient funds for the payment of principal of and interest on
      the
      applicable Notes as they would have become due if the Notes had not been
      declared due and payable, and the Indenture Trustee receives the consent of
      the
      Holders of 66 2/3% of the aggregate Note Principal Balance of the Notes then
      outstanding. In determining such sufficiency or insufficiency with respect
      to
      clause (B) and (C), the Indenture Trustee may, but need not, obtain and rely
      upon an opinion (obtained at the expense of the Trust) of an Independent
      investment banking or accounting firm of national reputation as to the
      feasibility of such proposed action and as to the sufficiency of the Trust
      Estate for such purpose. Notwithstanding the foregoing, so long as an Event
      of
      Master Servicer Termination has not occurred, any Sale of the Trust Estate
      shall
      be made subject to the continued servicing of the Mortgage Loans by the Servicer
      as provided in the related Servicing Agreement.

     

    (b)  If
      the
      Indenture Trustee collects any money or property with respect to the Group
      I
      Loans, Group II-C Loans or Group II-NC Loans, pursuant to this Article V, it
      shall pay out the money or property in the following order as determined by
      the
      Securities Administrator for each Loan Group:

     

    FIRST:
      to
      the Indenture Trustee, the Securities Administrator, the Master Servicer and
      Servicer for amounts due and not previously paid under
      the
      Basic Documents;

     

    SECOND:
      to the Cap Counterparty and the Corridor Provider, any amounts due and unpaid
      to
      the Cap Counterparty and the Corridor Provider under the Cap Contracts and
      the
      Corridor Contract, respectively;

     

    THIRD:
      to
      the related Noteholders, the amount of interest then due and unpaid on the
      related Notes (other than Basis Risk Shortfall Carry-Forward Amounts and Net
      WAC
      Shortfall Carry-Forward Amounts), first, to the related Class A Noteholders,
      on
      a pro
      rata basis,
      the
      related Accrued Note Interest for such Class, plus any related Unpaid Interest
      Shortfalls, and second, to the Class M Noteholders, sequentially, according
      to
      the amounts due and payable on such Notes for interest;

     

    FOURTH:
      to the related Noteholders the amount of principal then due and unpaid on the
      related Notes, and to each such Noteholder, on a pro rata basis, without
      preference or priority of any kind, until the Note Principal Balance of each
      such Class is reduced to zero;

     

    FIFTH:
      with respect to the Group I Loans, to the Class I-A-2, Class I-A-3 and Class
      I-M
      Notes, and with respect to the Group II-C Loans and Group II-NC Loans, II-A-2
      Notes or the Class II-A-4 Notes, as applicable, and Class II-B Notes and Class
      II-M Notes, in order of payment priority as set forth in Section 3.38, the
      amount of any related Allocated Realized Loss Amount not previously
      paid;

     

    SIXTH:
      to
      the related Notes, in order of payment priority, the amount of any related
      Basis
      Risk Shortfall Carry-Forward Amounts or Net WAC Shortfall Carry-Forward Amounts,
      as applicable, not previously paid; and

     

    SEVENTH:
      to the payment of the remainder, if any, to the Holder of the Trust Certificate
      on behalf of the Issuing Entity.

     

    The
      Indenture Trustee may fix a record date and Payment Date for any payment to
      Noteholders pursuant to this Section 5.04. At least 15 days before such record
      date, the Indenture Trustee shall mail to each Noteholder a notice that states
      the record date, the Payment Date and the amount to be paid.

     

    Section
      5.05  Optional
      Preservation of the Trust Estate.
      If the
      Notes have been declared to be due and payable under Section 5.02 following
      an
      Event of Default and such declaration and its consequences have not been
      rescinded and annulled, the Indenture Trustee may, and shall, at the written
      direction of the Holders of a majority of the aggregate Note Principal Balances
      of the Notes, elect to take and maintain possession of the Trust Estate. It
      is
      the desire of the parties hereto and the Noteholders that there be at all times
      sufficient funds for the payment of principal of and interest on the Notes
      and
      other obligations of the Issuing Entity and the Indenture Trustee, shall take
      such desire into account when determining whether or not to take and maintain
      possession of the Trust Estate. In determining whether to take and maintain
      possession of the Trust Estate, the Indenture Trustee may, but need not, obtain
      and rely upon an opinion of an Independent investment banking or accounting
      firm
      of national reputation as to the feasibility of such proposed action and as
      to
      the sufficiency of the Trust Estate for such purpose.

     

    Section
      5.06  Limitation
      of Suits.
      No
      Holder of any Note, shall have any right to institute any Proceeding, judicial
      or otherwise, with respect to this Indenture, or for the appointment of a
      receiver or trustee, or for any other remedy hereunder, unless and subject
      to
      the provisions of Section 10.16 hereof:

     

    (i)  such
      Holder has previously given written notice to the Indenture Trustee of a
      continuing Event of Default;

     

    (ii)  the
      Holders of not less than 25% of the aggregate Note Principal Balances of the
      Notes have made a written request to the Indenture Trustee to institute such
      Proceeding in respect of such Event of Default in its own name as Indenture
      Trustee hereunder;

     

    (iii)  such
      Holder or Holders have offered to the Indenture Trustee reasonable indemnity
      against the costs, expenses and liabilities to be incurred in complying with
      such request;

     

    (iv)  the
      Indenture Trustee, for 60 days after its receipt of such notice of request
      and
      offer of indemnity, has failed to institute such Proceedings; and

     

    (v)  no
      direction inconsistent with such written request has been given to the Indenture
      Trustee during such 60-day period by the Holders of a majority of the Note
      Principal Balances of the Notes.

     

    It
      is
      understood and intended that no one or more Holders of Notes shall have any
      right in any manner whatever by virtue of, or by availing of, any provision
      of
      this Indenture to affect, disturb or prejudice the rights of any other Holders
      of Notes or to obtain or to seek to obtain priority or preference over any
      other
      Holders or to enforce any right under this Indenture, except in the manner
      herein provided. No Holder of any Note shall have any right to institute any
      Proceeding, judicial or otherwise, with respect to a TMP Trigger Event, with
      respect to the meeting of the conditions to a REMIC Conversion or with respect
      to a REMIC Conversion.

     

    Subject
      to the last paragraph of Section 5.11 herein, in the event the Indenture Trustee
      shall receive conflicting or inconsistent requests and indemnity from two or
      more groups of Holders of Notes, each representing less than a majority of
      the
      Note Principal Balances of the Notes, the Indenture Trustee shall take the
      action requested by the group of Holders representing the largest percentage
      of
      the Note Principal Balance.

     

    Section
      5.07  Unconditional
      Rights of Noteholders To Receive Principal and Interest.
      Notwithstanding any other provisions in this Indenture, the Holder of any Note
      shall have the right, which is absolute and unconditional, to receive payment
      of
      the principal of and interest, if any, on such Note on or after the respective
      due dates thereof expressed in such Note or in this Indenture and to institute
      suit for the enforcement of any such payment, and such right shall not be
      impaired without the consent of such Holder. Notwithstanding the foregoing,
      in
      the event of a REMIC Conversion, Holders of Offered Notes shall receive, in
      a
      mandatory exchange for such Notes, REMIC Notes, whose principal and interest
      entitlement shall not be determined by this Indenture but rather by the
      provisions of an indenture and pooling and servicing agreement governing the
      cashflows of the REMIC Notes and REMIC Privately Offered Certificates, as
      applicable. In addition, in the event of a REMIC Conversion, Holders of the
      Non-Offered Notes shall receive, in a mandatory exchange for such Notes, REMIC
      Privately Offered Certificates, whose principal and interest entitlement shall
      not be determined by this Indenture but rather by the provisions of a pooling
      and servicing agreement governing the cashflows of the REMIC Privately Offered
      Certificates.

     

    Section
      5.08  Restoration
      of Rights and Remedies.
      If the
      Indenture Trustee or any Noteholder has instituted any Proceeding to enforce
      any
      right or remedy under this Indenture and such Proceeding has been discontinued
      or abandoned for any reason or has been determined adversely to the Indenture
      Trustee or to such Noteholder, then and in every such case the Issuing Entity,
      the Indenture Trustee and the Noteholders shall, subject to any determination
      in
      such Proceeding, be restored severally and respectively to their former
      positions hereunder, and thereafter all rights and remedies of the Indenture
      Trustee and the Noteholders shall continue as though no such Proceeding had
      been
      instituted.

     

    Section
      5.09  Rights
      and Remedies Cumulative.
      No
      right or remedy herein conferred upon or reserved to the Indenture Trustee
      or to
      the Noteholders is intended to be exclusive of any other right or remedy, and
      every right and remedy shall, to the extent permitted by law, be cumulative
      and
      in addition to every other right and remedy given hereunder or now or hereafter
      existing at law or in equity or otherwise. The assertion or employment of any
      right or remedy hereunder, or otherwise, shall not prevent the concurrent
      assertion or employment of any other appropriate right or remedy.

     

    Section
      5.10  Delay
      or Omission Not a Waiver.
      No
      delay or omission of the Indenture Trustee or any Holder of any Note to exercise
      any right or remedy accruing upon any Event of Default shall impair any such
      right or remedy or constitute a waiver of any such Event of Default or an
      acquiescence therein. Every right and remedy given by this Article V or by
      law
      to the Indenture Trustee or to the Noteholders may be exercised from time to
      time, and as often as may be deemed expedient, by the Indenture Trustee or
      by
      the Noteholders, as the case may be.

     

    Section
      5.11  Control
      By Noteholders.
      (i)
      With respect to the Notes, the Holders of a majority of the aggregate Note
      Principal Balances of Notes, shall have the right to direct the time, method
      and
      place of conducting any Proceeding for any remedy available to the Indenture
      Trustee with respect to the related Notes or exercising any trust or power
      conferred on the Indenture Trustee; provided that:

     

    (a)  such
      direction shall not be in conflict with any rule of law or with this
      Indenture;

     

    (b)  any
      direction to the Indenture Trustee to sell or liquidate the Trust Estate shall
      be by Holders of Notes representing not less than 100% of the Note Principal
      Balances of the Notes; and

     

    (c)  the
      Indenture Trustee may take any other action deemed proper by the Indenture
      Trustee that is not inconsistent with such direction of the Holders of Notes
      representing a majority of the Note Principal Balances of the
      Notes.

     

    Notwithstanding
      the rights of Noteholders set forth in this Section 5.11 the Indenture Trustee
      need not take any action that it determines might involve it in
      liability.

     

    Section
      5.12  Waiver
      of Past Defaults.
      Prior
      to the declaration of the acceleration of the maturity of the Notes as provided
      in Section 5.02 hereof, with respect to the Notes, the Holders of Notes
      representing not less than a majority of the aggregate Note Principal Balance
      of
      each Class of Notes may waive any past Event of Default and its consequences
      except an Event of Default (a) with respect to payment of principal of or
      interest on any of the Notes, or (b) in respect of a covenant or provision
      hereof which cannot be modified or amended without the consent of the Holder
      of
      each Note. In the case of any such waiver, the Issuing Entity, the Indenture
      Trustee and the Holders of the Notes shall be restored to their former positions
      and rights hereunder, respectively, but no such waiver shall extend to any
      subsequent or other Event of Default or impair any right consequent
      thereto.

     

    Upon
      any
      such waiver, any Event of Default arising therefrom shall be deemed to have
      been
      cured and not to have occurred for every purpose of this Indenture; but no
      such
      waiver shall extend to any subsequent or other Event of Default or impair any
      right consequent thereto.

     

    Section
      5.13  Undertaking
      for Costs.
      All
      parties to this Indenture agree, and each Holder of any Note and each Beneficial
      Owner of any interest therein by such Holder’s or Beneficial Owner’s acceptance
      thereof shall be deemed to have agreed, that any court may in its discretion
      require, in any suit for the enforcement of any right or remedy under this
      Indenture, or in any suit against the Indenture Trustee for any action taken,
      suffered or omitted by it as Indenture Trustee, the filing by any party litigant
      in such suit of an undertaking to pay the costs of such suit, and that such
      court may in its discretion assess reasonable costs, including reasonable
      attorneys’ fees, against any party litigant in such suit, having due regard to
      the merits and good faith of the claims or defenses made by such party litigant;
      but the provisions of this Section 5.13 shall not apply to (a) any suit
      instituted by the Indenture Trustee, (b) any suit instituted by any Noteholder,
      or group of Noteholders, in each case holding in the aggregate more than 10%
      of
      the Note Principal Balances of the Notes or (c) any suit instituted by any
      Noteholder for the enforcement of the payment of principal of or interest on
      any
      Note on or after the respective due dates expressed in such Note and in this
      Indenture.

     

    Section
      5.14  Waiver
      of Stay or Extension Laws.
      The
      Issuing Entity covenants (to the extent that it may lawfully do so) that it
      will
      not at any time insist upon, or plead or in any manner whatsoever, claim or
      take
      the benefit or advantage of, any stay or extension law wherever enacted, now
      or
      at any time hereafter in force, that may affect the covenants or the performance
      of this Indenture; and the Issuing Entity (to the extent that it may lawfully
      do
      so) hereby expressly waives all benefit or advantage of any such law, and
      covenants that it shall not hinder, delay or impede the execution of any power
      herein granted to the Indenture Trustee, but will suffer and permit the
      execution of every such power as though no such law had been
      enacted.

     

    Section
      5.15  Sale
      of Trust Estate.

     

    (a)  The
      power
      to effect any sale or other disposition (a “Sale”) of any portion of the Trust
      Estate pursuant to Section 5.04 hereof is expressly subject to the provisions
      of
      Sections 5.05 and 5.11(b) hereof and this Section 5.15. The power to effect
      any
      such Sale shall not be exhausted by any one or more Sales as to any portion
      of
      the Trust Estate remaining unsold, but shall continue unimpaired until the
      entire Trust Estate shall have been sold or all amounts payable on the Notes
      and
      under this Indenture shall have been paid. The Indenture Trustee may from time
      to time postpone any public Sale by public announcement made at the time and
      place of such Sale. The Indenture Trustee hereby expressly waives its right
      to
      any amount fixed by law as compensation for any Sale.

     

    (b)  The
      Indenture Trustee shall not in any private Sale sell the Trust Estate, or any
      portion thereof, unless

     

    (1)  the
      Holders of all Notes consent to or direct the Indenture Trustee to make, such
      Sale, or

     

    (2)  the
      proceeds of such Sale would be not less than the entire amount which would
      be
      payable to the Noteholders under the Notes on the Payment Date next succeeding
      the date of such Sale,

     

    (3)  the
      Indenture Trustee determines that the conditions for retention of the Trust
      Estate set forth in Section 5.05 hereof cannot be satisfied (in making any
      such
      determination, the Indenture Trustee may rely upon an opinion of an Independent
      investment banking firm obtained and delivered as provided in Section 5.05
      hereof), the Holders of Notes representing at least 100% of the Note Principal
      Balances of the Notes consent to such Sale; or

     

    (4)  such
      Sale
      occurs following the occurrence of a TMP Trigger Event in accordance with the
      terms and conditions of this Indenture and the Trust Agreement.

     

    The
      purchase by the Indenture Trustee of all or any portion of the Trust Estate
      at a
      private Sale shall not be deemed a Sale or other disposition thereof for
      purposes of this Section 5.15(b).

     

    (c)  [Reserved]

     

    (d)  In
      connection with a Sale of all or any portion of the Trust Estate,

     

    (1)  any
      Holder or Holders of Notes may bid for and purchase the property offered for
      sale, and upon compliance with the terms of sale may hold, retain and possess
      and dispose of such property, without further accountability, and may, in paying
      the purchase money therefor, deliver any Notes or claims for interest thereon
      in
      lieu of cash up to the amount which shall, upon distribution of the net proceeds
      of such sale, be payable thereon, and such Notes, in case the amounts so payable
      thereon shall be less than the amount due thereon, shall be returned to the
      Holders thereof after being appropriately stamped to show such partial
      payment;

     

    (2)  the
      Indenture Trustee may, but is in no event obligated to, bid for and acquire
      the
      property offered for Sale in connection with any Sale thereof, and, subject
      to
      any requirements of, and to the extent permitted by, applicable law in
      connection therewith, may purchase all or any portion of the Trust Estate in
      a
      private sale, and, in lieu of paying cash therefor, may make settlement for
      the

      on the Payment Date next succeeding the date of such Sale and (B) the expenses
      of the Sale and of any Proceedings in connection therewith which are
      reimbursable to it, without being required to produce the Notes in order to
      complete any such Sale or in order for the net Sale price to be credited against
      such Notes, and any property so acquired by the Indenture Trustee shall be
      held
      and dealt with by it in accordance with the provisions of this
      Indenture;

     

    (3)  the
      Indenture Trustee shall execute and deliver an appropriate instrument of
      conveyance, prepared by the Issuing Entity and satisfactory to the Indenture
      Trustee, transferring its interest in any portion of the Trust Estate in
      connection with a Sale thereof;

     

    (4)  the
      Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact
      of the Issuing Entity to transfer and convey its interest in any portion of
      the
      Trust Estate in connection with a Sale thereof, and to take all action necessary
      to effect such Sale; and

      Indenture Trustee’s right to seek and recover judgment on the Notes or under
      this Indenture shall not be affected by the seeking, obtaining or application
      of
      any other relief under or with respect to this Indenture. Neither the lien
      of
      this Indenture nor any rights or remedies of the Indenture Trustee or the
      Noteholders shall be impaired by the recovery of any judgment by the Indenture
      Trustee against the Issuing Entity or by the levy of any execution under such
      judgment upon any portion of the Trust Estate or upon any of the assets of
      the
      Issuing Entity. Any money or property collected by the Indenture Trustee shall
      be applied in accordance with Section 5.04(b) hereof.

      as the Indenture Trustee may request to cause the Issuing Entity to compel
      or
      secure the performance and observance by the Sponsor and the Servicer, as
      applicable, of each of their obligations to the Issuing Entity under or in
      connection with the Mortgage Loan Purchase Agreement and the Servicing
      Agreement, and to exercise any and all rights, remedies, powers and privileges
      lawfully available to the Issuing Entity under or in connection with the

    THE
      INDENTURE TRUSTEE AND THE SECURITIES ADMINISTRATOR

     

    Section
      6.01  Duties
      of Indenture Trustee and Securities Administrator.

     

    (a)  If
      an
      Event of Default has occurred and is continuing, the Indenture Trustee shall
      exercise the rights and powers vested in it by this Indenture 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.

     

    (b)  Except
      during the continuance of an Event of Default:

     

    (i)  the
      Indenture Trustee and the Securities Administrator undertakes to perform such
      duties and only such duties as are specifically set forth in this Indenture
      and
      no implied covenants or obligations shall be read into this Indenture against
      the Indenture Trustee or the Securities Administrator; and

     

    (ii)  in
      the
      absence of bad faith on its part, the Indenture Trustee and the Securities
      Administrator may each conclusively rely, as to the truth of the statements
      and
      the correctness of the opinions expressed therein, upon certificates, reports,
      documents, Issuing Entity Requests or other instruments or opinions furnished
      to
      each of the Indenture Trustee and the Securities Administrator and conforming
      to
      the requirements of this Indenture; however, the Indenture Trustee and the
      Securities Administrator shall examine the certificates, reports, documents,
      Issuing Entity Requests or other instruments and opinions to determine whether
      or not they conform to the requirements of this Indenture (but need not confirm
      or investigate the accuracy of mathematical calculations or other facts stated
      therein).

     

    (c)  The
      Indenture Trustee and the Securities Administrator may not be relieved from
      liability for its own negligent action, its own negligent failure to act or
      its
      own willful misconduct, except that:

     

    (i)  this
      paragraph does not limit the effect of paragraph (b) of this Section
      6.01;

     

    (ii)  neither
      the Indenture Trustee nor the Securities Administrator shall be liable
      for any error of judgment made in good faith by a Responsible Officer unless
      it
      is proved that the Indenture Trustee was negligent in ascertaining the pertinent
      facts;

     

    (iii)  neither
      the Indenture Trustee nor the Securities Administrator shall be liable with
      respect to any action it takes or omits to take in good faith in accordance
      with
      a written direction received by it from Noteholders, the Certificateholders
      or
      the Issuing Entity, which they are entitled to give under the Basic
      Documents;

     

    (iv)  neither
      the Indenture Trustee nor the Securities Administrator shall be liable for
      interest or income on any money received by it, except, in the case of the
      Securities Administrator, as set forth in the Basic Documents;

     

    (v)  money
      held in trust by the Indenture Trustee or the Securities Administrator need
      not
      be segregated from other trust funds except to the extent required by law or
      the
      terms of this Indenture or the Trust Agreement;

     

    (vi)  no
      provision of this Indenture or other Basic Document shall require the Indenture
      Trustee or the Securities
      Administrator to
      expend
      or risk its own funds or otherwise incur financial liability in the performance
      of any of its duties hereunder or in the exercise of any of its rights or
      powers, if it shall have reasonable grounds to believe that repayment of such
      funds or indemnity satisfactory to it against such risk or liability is not
      reasonably assured to it;

     

    (vii)  every
      provision of this Indenture or other Basic Document relating to the conduct
      or
      affecting the liability of or affording protection to the Indenture Trustee
      shall be subject to the provisions of this Section and to the provisions of
      the
      TIA;

     

    (viii)  the
      Indenture Trustee shall execute and act in accordance with the Servicing
      Agreement and
      the
      Master Servicing Agreement;
      in no
      event however, shall the Indenture Trustee or the Securities Administrator
      have
      any liability for any act or omission of the Master Servicer, the Servicer,
      any
      Subservicer or the Owner Trustee or for each other; and

     

    (ix)  the
      Indenture Trustee shall not be deemed to have notice or knowledge of any Default
      or Event of Default, any Servicer Default or other event unless a Responsible
      Officer of the Indenture Trustee has actual knowledge thereof or unless written
      notice of any such event that is in fact an Event of Default, Default, Servicer
      Default or other event is received by the Indenture Trustee at its Corporate
      Trust Office and such notice references the Notes or Certificates generally,
      the
      Issuing Entity, the Trust Estate or this Indenture.

     

    Section
      6.02  Rights
      of Indenture Trustee and the Securities Administrator.

     

    (a)  The
      Indenture Trustee and the Securities Administrator may rely conclusively on
      and
      shall be protected in acting or refraining from acting upon any resolution,
      certificate, statement, instrument, opinion, report, notice, request, direction,
      consent, order, bond, debenture, note, other evidence of indebtedness or other
      paper or document believed by it to be genuine and to have been signed or
      presented by the proper Person, party or parties. The Indenture Trustee and
      the
      Securities Administrator need not investigate any fact or matter stated in
      any
      such document.

     

    (b)  Before
      the Indenture Trustee or the Securities Administrator acts or refrains from
      acting, it may require an Officer’s Certificate or an Opinion of Counsel.
      Neither the Indenture Trustee nor the Securities Administrator shall be liable
      for any action it takes or omits to take in good faith in reliance on and in
      accordance with an Officer’s Certificate or Opinion of Counsel.

     

    (c)  Subject
      to the provisions of Section 6.01(c), neither the Indenture Trustee nor the
      Securities Administrator shall be liable for any action it takes or omits to
      take in good faith which it believes to be authorized or within its rights
      or
      powers.

     

    (d)  The
      Indenture Trustee and the Securities Administrator may each consult with counsel
      of its selection, and the written advice or Opinion of Counsel with respect
      to
      legal matters relating to this Indenture and the Notes or any Basic Document
      shall be full and complete authorization and protection from liability in
      respect to any action taken, omitted or suffered by it hereunder in good faith
      and in accordance with the written advice or Opinion of such
      counsel.

     

    (e)  For
      the
      limited purpose of effecting any action to be undertaken by each of the
      Indenture Trustee and the Securities Administrator, but not specifically as
      a
      duty of the Indenture Trustee or the Securities Administrator in the Indenture,
      each of the Indenture Trustee and the Securities Administrator may execute
      any
      of the trusts or powers hereunder or perform any duties hereunder, either
      directly or by or through agents, attorneys, custodians or nominees appointed
      with due care, and shall not be responsible for any willful misconduct or
      negligence on the part of any agent, attorney, custodian or nominee so
      appointed.

     

    (f)  The
      Indenture Trustee or its Affiliates are permitted to receive additional
      compensation that could be deemed to be in the Indenture 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
      Eligible Investments, (ii) using Affiliates to effect transactions in certain
      Eligible Investments and (iii) effecting transactions in certain Eligible
      Investments. Such compensation shall not be considered an amount, or effect
      a
      reduction in any amount, that is reimbursable or payable to the Indenture
      Trustee (i) as part of the Indenture Trustee Fee, (ii) pursuant to Sections
      5.04(b), 6.07, 8.02(c), 8.05(a) or 8.07 hereunder or (iii) out of Available
      Funds.

     

    (g)  In
      order
      to comply with laws, rules and regulations applicable to banking institutions,
      including those relating to the funding of terrorist activities and money
      laundering, the Indenture Trustee is required to obtain, verify and record
      certain information relating to individuals and entities which maintain a
      business relationship with the Indenture Trustee. Accordingly, each of the
      parties agrees to provide to the Indenture Trustee upon its request from time
      to
      time such party’s complete name, address, tax identification number and such
      other identifying information together with copies of such party’s constituting
      documentation, securities disclosure documentation and such other identifying
      documentation as may be available for such party.

     

    (h)  Whenever
      in the administration of this Indenture the Indenture Trustee or the Securities
      Administrator shall deem it desirable that a matter be proved or established
      prior to taking, suffering or omitting any action hereunder, the Indenture
      Trustee or the Securities Administrator (unless other evidence be herein
      specifically prescribed) may, in the absence of bad faith on its part,
      conclusively rely upon an Officer’s Certificate of the Issuing
      Entity.

     

    (i)  The
      rights, privileges, protections, immunities and benefits given to the Indenture
      Trustee, including, without limitation, its right to be indemnified, are
      extended to, and shall be enforceable by, the Indenture Trustee and the
      Securities Administrator in each of its capacities hereunder, and to each
      custodian employed to act hereunder.

     

    (j)  The
      Indenture Trustee and the Securities Administrator may request that the Issuing
      Entity deliver an Officer’s Certificate setting forth the names of individuals
      and/or titles of officers authorized at such time to take specified actions
      pursuant to this Indenture, which Officer’s Certificate may be signed by any
      person authorized to sign an Officer’s Certificate, including any person
      specified as so authorized in any such certificate previously delivered and
      not
      superseded.

     

    Section
      6.03  Individual
      Rights.
      Each of
      the Indenture Trustee and the Securities Administrator in its individual or
      any
      other capacity may become the owner or pledgee of Notes and may otherwise deal
      with the Issuing Entity or its Affiliates with the same rights it would have
      if
      it were not Indenture Trustee or Securities Administrator, as applicable,
      subject to the requirements of the Trust Indenture Act. Any Note Registrar,
      co-registrar or co-paying agent may do the same with like rights. However,
      the
      Indenture Trustee must comply with Sections 6.11 and 6.12 hereof.

     

    Section
      6.04  Indenture
      Trustee’s and Securities Administrator’s Disclaimer.
      The
      Indenture Trustee and the Securities Administrator shall not be responsible
      for
      and make no representation as to the validity or adequacy of this Indenture,
      the
      Notes or any other Basic Document, it shall not be accountable for the Issuing
      Entity’s use of the proceeds from the Notes, and it shall not be responsible for
      any statement of the Issuing Entity in the Indenture or in any document issued
      in connection with the sale of the Notes or in the Notes other than the
      Indenture Trustee’s certificate of authentication.

     

    Section
      6.05  Notice
      of Event of Default.
      Subject
      to Section 5.01, the Indenture Trustee shall promptly mail to each Noteholder
      notice of the Event of Default after it is known to a Responsible Officer of
      the
      Indenture Trustee, unless such Event of Default shall have been waived or cured.
      Except in the case of an Event of Default in payment of principal of or interest
      on any Note, the Indenture Trustee may withhold the notice if and so long as
      a
      committee of its Responsible Officers in good faith determines that withholding
      the notice is in the best interests of Noteholders.

     

    Section
      6.06  Reports
      by Securities Administrator to Holders and Tax Administration.
      The
Securities
      Administrator shall
      deliver to each Noteholder such information as may be required to enable such
      holder to prepare its federal and state income tax returns.

     

    The
      Securities Administrator shall prepare and file (or cause to be prepared and
      filed), on behalf of the Owner Trustee, all information reports on Form 1099
      required to be provided to Noteholders and the Holder of the Certificates.
      The
      Securities Administrator shall prepare and file all tax returns required to
      be
      filed on behalf of the Trust pursuant to Section 5.03 of the Trust Agreement.
      All tax returns and information reports shall be signed by the Owner Trustee
      as
      provided in Section 5.03 of the Trust Agreement.

     

    Section
      6.07  Compensation
      and Indemnity.
      The
      Indenture Trustee’s compensation shall not be limited by any law on compensation
      of a trustee of an express trust. The Issuing Entity shall reimburse the
      Indenture Trustee and the Securities Administrator as provided in Section
      8.02(c) for all reasonable out-of-pocket expenses incurred or made by it,
      including costs of collection, in addition to compensation for its services.
      Such expenses shall include reasonable compensation and expenses, disbursements
      and advances of the Indenture Trustee’s or Securities Administrator’s agents,
      counsel, accountants and experts. The Issuing Entity shall indemnify the
      Indenture Trustee and the Securities Administrator as provided in Section
      8.02(c) against any and all loss, liability, claims, damage, costs or expense
      (including reasonable attorneys’ fees and expenses) incurred by it in connection
      with the administration of this Trust and the performance of its duties
      hereunder and under the other Basic Documents. The Indenture Trustee and the
      Securities Administrator shall notify the Issuing Entity promptly of any claim
      for which it may seek indemnity. Failure by the Indenture Trustee or the
      Securities Administrator to so notify the Issuing Entity shall not relieve
      the
      Issuing Entity of its obligations hereunder. The Issuing Entity shall defend
      any
      such claim, and the Indenture Trustee and the Securities Administrator may
      have
      separate counsel and the Issuing Entity shall pay the fees and expenses of
      such
      counsel. The Issuing Entity is not obligated to reimburse any expense or
      indemnify against any loss, liability or expense incurred by the Indenture
      Trustee or the Securities Administrator or any of its agents, counsel,
      accountants or experts through the Indenture Trustee’s or such agent’s,
      counsel’s, accountant’s or expert’s own willful misconduct, negligence or bad
      faith.

     

    The
      Issuing Entity’s payment and indemnity obligations to the Indenture Trustee or
      the Securities Administrator pursuant to this Section 6.07 shall survive the
      discharge of this Indenture and the termination or resignation of the Indenture
      Trustee or the Securities Administrator. If the Indenture Trustee or the
      Securities Administrator incurs expenses after the occurrence of an Event of
      Default with respect to the Issuing Entity, the expenses are intended to
      constitute expenses of administration under Title 11 of the United States Code
      or any other applicable federal or state bankruptcy, insolvency or similar
      law.

     

    Section
      6.08  Replacement
      of Indenture Trustee and the Securities Administrator.
      No
      resignation or removal of the Indenture Trustee or the Securities Administrator
      and no appointment of a successor Indenture Trustee or successor Securities
      Administrator shall become effective until the acceptance of appointment by
      the
      successor Indenture Trustee or successor Securities Administrator pursuant
      to
      this Section 6.08. The Indenture Trustee or the Securities Administrator may
      resign at any time by so notifying the Issuing Entity. The Holders of a majority
      of Note Principal Balances of each Class of Notes may remove the Indenture
      Trustee or the Securities Administrator by so notifying the Indenture Trustee
      or
      the Securities Administrator and may appoint a successor Indenture Trustee
      or
      successor Securities Administrator. The Issuing Entity shall remove the
      Indenture Trustee or Securities Administrator , as applicable, if:

     

    (i)  the
      Indenture Trustee fails to comply with or qualify pursuant to the provisions
      of
      Section 6.11 hereof;

     

    (ii)  the
      Indenture Trustee or the Securities Administrator is adjudged a bankrupt or
      insolvent;

     

    (iii)  a
      receiver or other public officer takes charge of the Indenture Trustee or the
      Securities Administrator or its property; or

     

    (iv)  the
      Indenture Trustee or the Securities Administrator otherwise becomes incapable
      of
      acting.

     

    (v)  If
      the
      Indenture Trustee or the Securities Administrator resigns or is removed or
      if a
      vacancy exists in the office of the Indenture Trustee or the Securities
      Administrator for any reason (the Indenture Trustee or the Securities
      Administrator in such event being referred to herein as the retiring Indenture
      Trustee or retiring Securities Administrator), the Issuing Entity shall promptly
      appoint a successor Indenture Trustee or successor Securities
      Administrator.

     

    Each
      of a
      successor Indenture Trustee or successor Securities Administrator shall deliver
      a written acceptance of its appointment to the retiring Indenture Trustee,
      retiring Securities Administrator and to the Issuing Entity. Thereupon, the
      resignation or removal of the retiring Indenture Trustee or retiring Securities
      Administrator shall become effective, and the successor Indenture Trustee or
      successor Securities Administrator shall have all the rights, powers and duties
      of the Indenture Trustee or Securities Administrator under this Indenture.
      Each
      of the successor Indenture Trustee and successor Securities Administrator shall
      mail a notice of its succession to Noteholders. The retiring Indenture Trustee
      or retiring Securities Administrator shall promptly transfer all property held
      by it as Indenture Trustee or Securities Administrator to the successor
      Indenture Trustee or successor Securities Administrator.

     

    If
      a
      successor Indenture Trustee or successor Securities Administrator does not
      take
      office within 60 days after the retiring Indenture Trustee or retiring
      Securities Administrator resigns or is removed, the retiring Indenture Trustee
      or retiring Securities Administrator, the successor Indenture Trustee or
      successor Securities Administrator, the Issuing Entity or the Holders of a
      majority of Note Principal Balances of the Notes may petition any court of
      competent jurisdiction for the appointment of a successor Indenture Trustee
      or
      successor Securities Administrator.

     

    Notwithstanding
      the replacement of the Indenture Trustee or the Securities Administrator
      pursuant to this Section, the Issuing Entity’s obligations under
      Section 6.07 shall continue for the benefit of the retiring Indenture
      Trustee or retiring Securities Administrator.

     

    Section
      6.09  Successor
      Indenture Trustee and Successor Securities Administrator by
      Merger.
      If the
      Indenture Trustee or Securities Administrator consolidates with, merges or
      converts into, or transfers all or substantially all of its corporate trust
      business or assets to, another corporation, company or banking association,
      the
      resulting, surviving or transferee corporation, without any further act, shall
      be the successor Indenture Trustee or successor Securities Administrator;
      provided, that, in the case of the Indenture Trustee, such corporation, company
      or banking association shall be otherwise qualified and eligible under Section
      6.11 hereof. The Indenture Trustee and Securities Administrator shall each
      provide the Rating Agencies and the Issuing Entity with prior written notice,
      and the Noteholders with prompt written notice, of any such
      transaction.

     

    If
      at the
      time such successor or successors by merger, conversion or consolidation to
      the
      Indenture Trustee or shall succeed to the trusts created by this Indenture
      and
      any of the Notes shall have been authenticated but not delivered, any such
      successor to the Indenture Trustee may adopt the certificate of authentication
      of any predecessor trustee and deliver such Notes so authenticated; and if
      at
      that time any of the Notes shall not have been authenticated, any successor
      to
      the Indenture Trustee may authenticate such Notes either in the name of any
      predecessor hereunder or in the name of the successor to the Indenture Trustee;
      and in all such cases such certificates shall have the full force which is
      in
      the Notes or in this Indenture provided that the certificate of the Indenture
      Trustee shall have.

     

    Section
      6.10  Appointment
      of Co-Indenture Trustee or Separate Indenture Trustee.

     

    (a)  Notwithstanding
      any other provisions of this Indenture, at any time, for the purpose of meeting
      any legal requirement of any jurisdiction in which any part of the Trust Estate
      may at the time be located, the Indenture Trustee shall have the power and
      may
      execute and deliver all instruments to appoint one or more Persons to act as
      a
      co-trustee or co-trustees, or separate trustee or separate trustees, of all
      or
      any part of the Trust Estate, and to vest in such Person or Persons, in such
      capacity and for the benefit of the Noteholders, such title to the Trust Estate,
      or any part hereof, and, subject to the other provisions of this Section, such
      powers, duties, obligations, rights and trusts as the Indenture Trustee may
      consider necessary or desirable. No co-trustee or separate trustee hereunder
      shall be required to meet the terms of eligibility as a successor trustee under
      Section 6.11 hereof.

     

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

     

    (i)  all
      rights, powers, duties and obligations conferred or imposed upon the Indenture
      Trustee shall be conferred or imposed upon and exercised or performed by the
      Indenture 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 Indenture 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 the Indenture Trustee shall be incompetent or
      unqualified to perform such act or acts, in which event such rights, powers,
      duties and obligations (including the holding of title to the Trust Estate
      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 Indenture Trustee;

     

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

     

    (iii)  the
      Indenture Trustee may at any time accept the resignation of or remove any
      separate trustee or co-trustee.

     

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

     

    (v)  Any
      separate trustee or co-trustee may at any time constitute the Indenture 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 Indenture
      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
      Indenture Trustee, to the extent permitted by law, without the appointment
      of a
      new or successor trustee.

     

    Section
      6.11  Eligibility;
      Disqualification. 

     

    (a)  The
      Indenture Trustee shall at all times satisfy the requirements of TIA § 310(a).
      The Indenture Trustee shall have a combined capital and surplus of at least
      $50,000,000 as set forth in its most recent published annual report of condition
      and it or its parent shall have a long-term debt rating of Baa3 or better by
      Moody’s and BBB or better by Standard & Poor’s. The Indenture Trustee shall
      comply with TIA § 310(b), including the optional provision permitted by the
      second sentence of TIA § 310(b)(9); provided,
      however,
      that
      there shall be excluded from the operation of TIA § 310(b)(1) any indenture or
      indentures under which other securities of the Issuing Entity are outstanding
      if
      the requirements for such exclusion set forth in TIA § 310(b)(1) are
      met.

     

    (b)  The
      Securities Administrator (i) may not be an Originator, Master Servicer,
      Servicer, the Depositor or an affiliate of the Depositor unless the Securities
      Administrator is in an institutional trust department, (ii) must be authorized
      to exercise corporate trust powers under the laws of its jurisdiction of

      a
      Rating Agency (or such rating acceptable to Fitch pursuant to a rating
      confirmation), or the equivalent rating by Standard & Poor’s or Moody's. If
      no successor Securities Administrator shall have been appointed and shall have
      accepted appointment within 60 days after the Securities Administrator ceases
      to
      be the securities administrator pursuant to Section 6.08, then the Indenture
      Trustee shall become the successor Securities Administrator in accordance with
      this Article VI and in such capacity shall perform the duties of the Securities
      Administrator pursuant to this Agreement. The Indenture Trustee shall notify
      the
      Rating Agencies of any change of Securities Administrator. 

     

    Section
      6.12  Preferential
      Collection of Claims Against Issuing Entity.
      The
      Indenture Trustee shall comply with TIA § 311(a), excluding any creditor
      relationship listed in TIA § 311(b). An Indenture Trustee who has resigned or
      been removed shall be subject to TIA § 311(a) to the extent
      indicated.

      deal with any of its Affiliates; provided, however, that the terms of any such
      transactions or dealings shall be in accordance with any directions received
      from the Issuing Entity and shall be, in the Indenture Trustee’s opinion, no
      less favorable to the Issuing Entity than would be available from unaffiliated
      parties.

     

    (c)  The

      of Derivative Contracts and other Documents.
      The
      Issuing Entity hereby directs the Indenture Trustee to enter into and execute

    Section
      6.20  Indenture
      Trustee’s Application For Instructions From the Issuing Entity.

     

    Any

      Entity may, at the option of the Indenture Trustee, set forth in writing any
      action proposed to be taken or omitted by the Indenture Trustee under this
      Indenture and the date on and/or after which such action shall be taken or
      such
      omission shall be effective. The Indenture Trustee shall not be liable for
      any
      action taken by, or omission of, the Indenture Trustee in accordance with a
      proposal included in such application on or after the date specified in such
      application (which date shall not be less than three Business Days after the
      date any officer of the Issuing Entity actually receives such application,
      unless any such officer shall have consented in writing to any earlier date)
      unless prior to taking any such action (or the effective date in the case of
      an
      omission), the Indenture Trustee shall have received written instructions in
      response to such application specifying the action to be taken or
      omitted.

     

    Section
      6.21  Limitation
      of Liability.

     

    It
      is
      understood by the parties hereto other than Deutsche Bank National Trust Company
      (the “Bank”) that the sole recourse of the parties hereto other than the Bank in
      respect of the obligations of the Trust hereunder and under the other documents
      contemplated thereby and related thereto to which it is a party shall be to
      the
      parties hereto other than the Bank. In addition, the Bank is entering into
      this
      Indenture and the other documents contemplated thereby and related thereto
      to
      which it is a party solely in its capacity as Indenture Trustee under the
      Indenture and not in its individual capacity (except as expressly stated herein)
      and in no case shall the Bank (or any Person acting as successor Indenture
      Trustee under the Indenture) be personally liable for or on account of any
      of
      the statements, representations, warranties, covenants or obligations stated
      to
      be those of the Issuing Entity hereunder or thereunder, all such liability,
      if
      any, being expressly waived by the parties hereto and any person claiming by,
      through or under such party, provided, however, that the Bank (or any such
      successor Indenture Trustee) shall be personally liable hereunder and thereunder
      for its own negligence or willful misconduct or for its material breach of
      its
      covenants, representations and warranties contained herein or therein, to the
      extent expressly covenanted or made in its individual capacity. In no event
      shall the Indenture Trustee, in its capacity as Paying Agent, Note Registrar
      or
      in any other capacity hereunder, be liable under or in connection with this
      Indenture for indirect, special, incidental, punitive or consequential losses
      or
      damages of any kind whatsoever, including but not limited to lost profits,
      whether or not foreseeable, even if the Indenture Trustee has been advised
      of
      the possibility thereof and regardless of the form of action in which such
      damages are sought. The provisions of this section shall survive the termination
      of the Indenture and the resignation or removal of the Indenture
      Trustee.

     

    Section
      6.22  Assignment
      of Rights, Not Assumption of Duties.

     

    Anything
      herein contained to the contrary notwithstanding, (a) the Issuing Entity shall
      remain liable under this Indenture and each Basic Document to which it is a
      party to the extent set forth therein to perform all of its duties and
      obligations thereunder to the same extent as if this Indenture had not been
      executed, (b) the exercise by the Indenture Trustee or any Holder of any of
      their rights, remedies or powers hereunder shall not release the Issuing Entity
      from any of its duties or obligations under each of such documents to which
      it
      is a party and (c) none of any Holder nor the Indenture Trustee shall have
      any
      obligation or liability under any of such documents to which the Issuing Entity
      is a party by reason of or arising out of this Indenture, nor shall any Holder
      or the Indenture Trustee be obligated to perform any of the obligations or
      duties of the Issuing Entity thereunder or, except as expressly provided herein
      with respect to the Indenture Trustee, to take any action to collect or enforce
      any claim for payment assigned hereunder or otherwise.

      shall have received an Opinion of Counsel as to the enforceability of any such
      indenture supplement, and that, except for indenture supplements entered into
      for the purposes described in (v) and (viii) above, such indenture supplements
      shall not adversely affect in any material respect the interests of any
      Noteholder and to the effect that (i) such indenture supplement is permitted
      hereunder and (ii) entering into such indenture supplement will not result
      in a
“substantial modification” of the Notes under Treasury Regulation Section
      1.1001-3 or adversely affect the status of the Notes as indebtedness for federal
      income tax purposes, provided that, for purposes of the foregoing, a TMP Trigger
      Event shall be deemed to result in a “significant modification” of the
      aforementioned Notes under Treasury Regulation Section 1.1001-3.

     

    The
      Indenture Trustee is hereby authorized to join in the execution of any such
      supplemental indenture and to make any further appropriate agreements and
      stipulations that may be therein contained.

     

    (b)  The
      Issuing Entity, the Securities Administrator and the Indenture Trustee, when
      authorized by an Issuing Entity Request, may, also without the consent of any
      of
      the Holders of the Notes and prior notice to the Rating Agencies, enter into
      an
      indenture or indentures supplemental hereto for the purpose of adding any
      provisions to, or changing in any manner or eliminating any of the provisions
      of, this Indenture or of modifying in any manner the rights of the Holders
      of
      the Notes under this Indenture; provided,
      however,
      that
      such action as evidenced by an Opinion of Counsel, (i) is permitted by this
      Indenture, (ii) shall not adversely affect in any material respect the interests
      of any Noteholder and (iii) if 100% of the Certificates and the Retained Notes
      (to the extent that such Retained Notes have not received a “will be debt”
opinion) are not owned by American Home Mortgage Acceptance, Inc., cause the
      Issuing Entity to be subject to an entity level tax for federal income tax
      purposes.

     

    Section
      9.02  Supplemental
      Indentures With Consent of Noteholders.
      The
      Issuing Entity, the Securities Administrator and the Indenture Trustee, when
      authorized by an Issuing Entity Request, also may, with prior notice to the
      Rating Agencies and, with the consent of the Holders of not less than a majority
      of the Note Principal Balance of each Class of Notes affected thereby, by Act
      (as defined in Section 10.03 hereof) of such Holders, delivered to the Issuing
      Entity, the Securities Administrator and the Indenture Trustee, enter into
      an
      indenture or indentures supplemental hereto for the purpose of adding any
      provisions to, or changing in any manner or eliminating any of the provisions
      of, this Indenture or of modifying in any manner the rights of the Holders
      of
      the Notes under this Indenture; provided,
      however,
      that no
      such supplemental indenture shall, without the consent of the Holder of each
      Note affected thereby:

     

    (i)  change
      the date of payment of any installment of principal of or interest on any Note,
      or reduce the principal amount thereof or the interest rate thereon, change
      the
      provisions of this Indenture relating to the application of collections on,
      or
      the proceeds of the sale of, the Trust Estate and to payment of principal of
      or
      interest on the Notes, or change any place of payment where, or the coin or
      currency in which, any Note or the interest thereon is payable, or impair the
      right to institute suit for the enforcement of the provisions of this Indenture
      requiring the application of funds available therefor, as provided in Article
      V,
      to the payment of any such amount due on the Notes on or after the respective
      due dates thereof;

     

    (ii)  reduce
      the percentage of the Note Principal Balances of the Notes, or any Class of
      Notes, the consent of the Holders of which is required for any such supplemental
      indenture, or the consent of the Holders of which is required for any waiver
      of
      compliance with certain provisions of this Indenture or certain defaults
      hereunder and their consequences provided for in this Indenture;

     

    (iii)  modify
      or
      alter the provisions of the proviso to the definition of the term “Outstanding”
or modify or alter the exception in the definition of the term
“Holder”;

     

    (iv)  reduce
      the percentage of the Note Principal Balances of the Notes, or any Class of
      Notes, required to direct the Indenture Trustee to direct the Issuing Entity
      to
      sell or liquidate the Trust Estate pursuant to Section 5.04 hereof;

     

    (v)  modify
      any provision of this Section 9.02 except to increase any percentage specified
      herein or to provide that certain additional provisions of this Indenture or
      the
      Basic Documents cannot be modified or waived without the consent of the Holder
      of each Note affected thereby;

     

    (vi)  modify
      any of the provisions of this Indenture in such manner as to affect the
      calculation of the amount of any payment of interest or principal due on any
      Note on any Payment Date (including the calculation of any of the individual
      components of such calculation); or

     

    (vii)  permit
      the creation of any lien ranking prior to or on a parity with the lien of this
      Indenture with respect to any part of the Trust Estate or, except as otherwise
      permitted or contemplated herein, terminate the lien of this Indenture on any
      property at any time subject hereto or deprive the Holder of any Note of the
      security provided by the lien of this Indenture;

     

    and
      provided,
      further,
      that
      such action shall not, as evidenced by an Opinion of Counsel, cause the Issuing
      Entity (if 100% of the Certificates and the Retained Notes (to the extent that
      such Retained Notes have not received a “will be debt” opinion) are not owned by
      American Home Mortgage Acceptance Inc.) to be subject to an entity level tax
      for
      federal income tax purposes.

     

    Any
      such
      action shall not adversely affect in any material respect the interest of any
      Holder (other than a Holder who shall consent to such supplemental indenture)
      as
      evidenced by an Opinion of Counsel (provided by the Person requesting such
      supplemental indenture) delivered to the Indenture Trustee.

     

    It
      shall
      not be necessary for any Act of Noteholders under this Section 9.02 to approve
      the particular form of any proposed supplemental indenture, but it shall be
      sufficient if such Act shall approve the substance thereof.

     

    Promptly
      after the execution by the Issuing Entity, the Securities Administrator and
      the
      Indenture Trustee of any supplemental indenture pursuant to this Section 9.02,
      the Indenture Trustee shall mail to the Owner Trustee and the Holders of the
      Notes to which such amendment or supplemental indenture relates a notice setting
      forth in general terms the substance of such supplemental indenture. Any failure
      of the Indenture Trustee to mail such notice, or any defect therein, shall
      not,
      however, in any way impair or affect the validity of any such supplemental
      indenture.

     

    Section
      9.03  Execution
      of Supplemental Indentures.
      In
      executing, or permitting the additional trusts created by, any supplemental
      indenture permitted by this Article VI or the modification thereby of the trusts
      created by this Indenture, the Indenture Trustee shall be entitled to receive,
      and subject to Sections 6.01 and 6.02 hereof, shall be fully protected in
      relying upon, an Opinion of Counsel stating that the execution of such
      supplemental indenture is authorized or permitted by this Indenture and that
      all
      conditions precedent thereto have been complied with. The Indenture Trustee
      may,
      but shall not be obligated to, enter into any such supplemental indenture that
      affects the Indenture Trustee’s own rights, duties, liabilities or immunities
      under this Indenture or otherwise.

     

    Section
      9.04  Effect
      of Supplemental Indenture.
      Upon
      the execution of any supplemental indenture pursuant to the provisions hereof,
      this Indenture shall be and shall be deemed to be modified and amended in
      accordance therewith with respect to the Notes affected thereby, and the
      respective rights, limitations of rights, obligations, duties, liabilities
      and
      immunities under this Indenture of the Indenture Trustee, the Issuing Entity
      and
      the Holders of the Notes shall thereafter be determined, exercised and enforced
      hereunder subject in all respects to such modifications and amendments, and
      all
      the terms and conditions of any such supplemental indenture shall be and be
      deemed to be part of the terms and conditions of this Indenture and the Notes
      for any and all purposes.

     

    Section
      9.05  Conformity
      with Trust Indenture Act.
      Every
      amendment of this Indenture and every supplemental indenture executed pursuant
      to this Article IX shall conform to the requirements of the Trust Indenture
      Act
      as then in effect so long as this Indenture shall then be qualified under the
      Trust Indenture Act.

     

    Section
      9.06  Reference
      in Notes to Supplemental Indentures.
      Notes
      authenticated and delivered after the execution of any supplemental indenture
      pursuant to this Article IX may, and if required by the Indenture Trustee shall,
      bear a notation in form approved by the Indenture Trustee as to any matter
      provided for in such supplemental indenture. If the Issuing Entity or the
      Indenture Trustee shall so determine, new Notes so modified as to conform,
      in
      the opinion of the Indenture Trustee and the Issuing Entity, to any such
      supplemental indenture may be prepared and executed by the Issuing Entity and
      authenticated and delivered by the Indenture Trustee in exchange for Outstanding
      Notes.

    Section
      10.01  Compliance
      Certificates and Opinions, etc.
      (a)
      Upon any
      application or request by the Issuing Entity to the Indenture Trustee to take
      any action under any provision of this Indenture, the Issuing Entity shall
      furnish to the Indenture Trustee (i) an Officer’s Certificate stating that all
      conditions precedent, if any, provided for in this Indenture relating to the
      proposed action have been complied with and (ii) an Opinion of Counsel stating
      that in the opinion of such counsel all such conditions precedent, if any,
      have
      been complied with, except that, in the case of any such application or request
      as to which the furnishing of such documents is specifically required by any
      provision of this Indenture, no additional certificate or opinion need be
      furnished.

     

    Every
      certificate or opinion with respect to compliance with a condition or covenant
      provided for in this Indenture shall include:

     

    (1)  a
      statement that each signatory of such certificate or opinion has read or has
      caused to be read such covenant or condition and the definitions herein relating
      thereto;

     

    (2)  a
      brief
      statement as to the nature and scope of the examination or investigation upon
      which the statements or opinions contained in such certificate or opinion are
      based;

     

    (3)  a
      statement that, in the opinion of each such signatory, such signatory has made
      such examination or investigation as is necessary to enable such signatory
      to
      express an informed opinion as to whether or not such covenant or condition
      has
      been complied with;

     

    (4)  a
      statement as to whether, in the opinion of each such signatory, such condition

      signatory of such certificate or opinion is required to be Independent, the
      statement required by the definition of the term “Independent”.

     

    (b)  Prior
      to
      the deposit of any Collateral or other property or securities with the Indenture
      Trustee that is to be made the basis for the release of any property or
      securities subject to the lien of this Indenture, the Issuing Entity shall,
      in
      addition to any obligation imposed in Section 10.01 (a) or elsewhere in this
      Indenture, furnish to the Indenture Trustee an Officer’s Certificate certifying
      or stating the opinion of each person signing such certificate as to the fair
      value (within 90 days prior to such deposit) to the Issuing Entity of the
      Collateral or other property or securities to be so deposited and a report
      from
      a nationally recognized accounting firm verifying such value.

     

    (c)  Whenever
      the Issuing Entity is required to furnish to the Indenture Trustee an Officer’s
      Certificate certifying or stating the opinion of any signer thereof as to the
      matters described in clause (i) above, the Issuing Entity shall also deliver
      to
      the Indenture Trustee an Independent Certificate from a nationally recognized
      accounting firm as to the same matters, if the fair value of the securities
      to
      be so deposited and of all other such securities made the basis of any such
      withdrawal or release since the commencement of the then current fiscal year
      of
      the Issuing Entity, as set forth in the certificates delivered pursuant to
      clause (i) above and this clause (ii), is 10% or more of the Note Principal
      Balances of the Notes, but such a certificate need not be furnished with respect
      to any securities so deposited, if the fair value thereof as set forth in the
      related Officer’s Certificate is less than $25,000 or less than one percent of
      the then outstanding Note Principal Balances of the Notes.

     

    (d)  Whenever
      any property or securities are to be released from the lien of this Indenture,

      certificate as to the fair value (within 90 days prior to such release) of
      the
      property or securities proposed to be released and stating that in the opinion
      of such person the proposed release will not impair the security under this
      Indenture in contravention of the provisions hereof.

     

    (e)  Whenever
      the Issuing Entity is required to furnish to the Indenture Trustee an Officer’s
      Certificate certifying or stating the opinion of any signer thereof as to the
      matters described in clause (iii) above, the Issuing Entity shall also furnish
      to the Indenture Trustee an Independent Certificate as to the same matters
      if
      the fair value of the property or securities and of all other property or
      securities released from the lien of this Indenture since the commencement
      of
      the then-current calendar year, as set forth in the certificates required by
      clause (iii) above and this clause (iv), equals 10% or more of the Note
      Principal Balances of the Notes, but such certificate need not be furnished
      in
      the case of any release of property or securities if the fair value thereof
      as
      set forth in the related Officer’s Certificate is less than $25,000 or less than
      one percent of the then outstanding Note Principal Balances of the
      Notes.

     

    Section
      10.02  Form
      of Documents Delivered to Indenture Trustee.
      In any
      case where several matters are required to be certified by, or covered by an
      opinion of, any specified Person, it is not necessary that all such matters
      be
      certified by, or covered by the opinion of, only one such Person, or that they
      be so certified or covered by only one document, but one such Person may certify
      or give an opinion with respect to some matters and one or more other such
      Persons as to other matters, and any such Person may certify or give an opinion
      as to such matters in one or several documents.

     

    Any
      certificate or opinion of an Authorized Officer of the Issuing Entity may be
      based, insofar as it relates to legal matters, upon a certificate or opinion
      of,
      or representations by, counsel, unless such officer knows, or in the exercise
      of
      reasonable care should know, that the certificate or opinion or representations
      with respect to the matters upon which his certificate or opinion is based
      are
      erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel
      may be based, insofar as it relates to factual matters, upon a certificate
      or
      opinion of, or representations by, an officer or officers of the Sponsor or
      the
      Issuing Entity, stating that the information with respect to such factual
      matters is in the possession of the Sponsor or the Issuing Entity, unless such
      counsel knows, or in the exercise of reasonable care should know, that the
      certificate or opinion or representations with respect to such matters are
      erroneous.

     

    Where
      any
      Person is required to make, give or execute two or more applications, requests,
      consents, certificates, statements, opinions or other instruments under this
      Indenture, they may, but need not, be consolidated and form one
      instrument.

     

    Whenever
      in this Indenture, in connection with any application or certificate or report
      to the Indenture Trustee, it is provided that the Issuing Entity shall deliver
      any document as a condition of the granting of such application, or as evidence
      of the Issuing Entity’s compliance with any term hereof, it is intended that the
      truth and accuracy, at the time of the granting of such application or at the
      effective date of such certificate or report (as the case may be), of the facts
      and opinions stated in such document shall in such case be conditions precedent
      to the right of the Issuing Entity to have such application granted or to the
      sufficiency of such certificate or report. The foregoing shall not, however,
      be
      construed to affect the Indenture Trustee’s right to rely upon the truth and
      accuracy of any statement or opinion contained in any such document as provided
      in Article VI.

     

    Section
      10.03  Acts
      of Noteholders.

     

    (a)  Any
      request, demand, authorization, direction, notice, consent, waiver or other
      action provided by this Indenture to be given or taken by Noteholders may be
      embodied in and evidenced by one or more instruments of substantially similar
      tenor signed by such Noteholders in person or by agents duly appointed in
      writing; and except as herein otherwise expressly provided, such action shall
      become effective when such instrument or instruments are delivered to the
      Indenture Trustee, and, where it is hereby expressly required, to the Issuing
      Entity. Such instrument or instruments (and the action embodied therein and
      evidenced thereby) are herein sometimes referred to as the “Act” of the
      Noteholders signing such instrument or instruments. Proof of execution of any
      such instrument or of a writing appointing any such agent shall be sufficient
      for any purpose of this Indenture and (subject to Section 6.01 hereof)
      conclusive in favor of the Indenture Trustee and the Issuing Entity, if made
      in
      the manner provided in this Section 10.03 hereof.

     

    (b)  The
      fact
      and date of the execution by any person of any such instrument or writing may
      be
      proved in any manner that the Indenture Trustee deems sufficient.

     

    (c)  The
      ownership of Notes shall be proved by the Note Registrar.

     

    (d)  Any
      request, demand, authorization, direction, notice, consent, waiver or other
      action by the Holder of any Notes shall bind the Holder of every Note issued
      upon the registration thereof or in exchange therefor or in lieu thereof, in
      respect of anything done, omitted or suffered to be done by the Indenture
      Trustee or the Issuing Entity in reliance thereon, whether or not notation
      of
      such action is made upon such Note.

      10.04  Notices
      etc., to Indenture Trustee, Issuing Entity, Securities Administrator and Rating

      from the Noteholders to the Issuing Entity; or

     

    (b)  the
      Issuing Entity by the Indenture Trustee or by any Noteholder shall be sufficient
      for every purpose hereunder if made, given, furnished or filed in writing and
      mailed first-class, postage prepaid to the Issuing Entity addressed to: American

      previously furnished in writing to the Indenture Trustee by the Issuing Entity.
      The Issuing Entity shall promptly transmit any notice received by it from the
      Noteholders to the Indenture Trustee; or

     

    (c)  the
      Securities Administrator by the Indenture Trustee, any Noteholder or by the

      Issuing Entity; or

     

    (d)  Notices

    Section
      10.05  Notices
      to Noteholders; Waiver.
      Where
      this Indenture provides for notice to Noteholders of any event, such notice
      shall be sufficiently given (unless otherwise herein expressly provided) if
      made, given, furnished or filed in writing and mailed, first-class, postage
      prepaid to each Noteholder affected by such event, at such Person’s address as
      it appears on the Note Register, not later than the latest date, and not earlier
      than the earliest date, prescribed for the giving of such notice. In any case
      where notice to Noteholders is given by mail, neither the failure to mail such
      notice nor any defect in any notice so mailed to any particular Noteholder
      shall
      affect the sufficiency of such notice with respect to other Noteholders, and
      any
      notice that is mailed in the manner herein provided shall conclusively be
      presumed to have been duly given regardless of whether such notice is in fact
      actually received.

     

    Where
      this Indenture provides for notice in any manner, such notice may be waived
      in
      writing by any Person entitled to receive such notice, either before or after
      the event, and such waiver shall be the equivalent of such notice. Waivers
      of
      notice by Noteholders shall be filed with the Indenture Trustee but such filing
      shall not be a condition precedent to the validity of any action taken in
      reliance upon such a waiver.

     

    In
      case,
      by reason of the suspension of regular mail service as a result of a strike,
      work stoppage or similar activity, it shall be impractical to mail notice of
      any
      event to Noteholders when such notice is required to be given pursuant to any
      provision of this Indenture, then any manner of giving such notice as shall
      be
      satisfactory to the Indenture Trustee shall be deemed to be a sufficient giving
      of such notice.

     

    Where
      this Indenture provides for notice to the Rating Agencies, failure to give
      such
      notice shall not affect any other rights or obligations created hereunder,
      and
      shall not under any circumstance constitute an Event of Default.

     

    Section
      10.06  Conflict
      with Trust Indenture Act.
      If any
      provision hereof limits, qualifies or conflicts with another provision hereof
      that is required to be included in this Indenture by any of the provisions
      of
      the Trust Indenture Act, such required provision shall control.

     

    The
      provisions of TIA §§ 310 through 317 that impose duties on any Person (including
      the provisions automatically deemed included herein unless expressly excluded
      by
      this Indenture) are a part of and govern this Indenture, whether or not
      physically contained herein.

      10.08  Successors
      and Assigns.

      shall bind its successors and assigns, whether so expressed or not. All
      agreements of the Indenture Trustee in this Indenture shall bind its successors,
      co-trustees and agents.

     

    Section
      10.09  Separability.
      In case
      any provision in this Indenture or in the Notes shall be invalid, illegal or
      unenforceable, the validity, legality, and enforceability of the remaining
      provisions shall not in any way be affected or impaired thereby.

     

    Section
      10.10  Benefits
      of Indenture.
      Nothing
      in this Indenture or in the, express or implied, shall give to any Person,
      other
      than the parties hereto and their successors hereunder and the Noteholders,
      any
      benefit or any legal or equitable right, remedy or claim under this
      Indenture.

     

    Section
      10.11  Legal
      Holidays.
      In any
      case where the date on which any payment is due shall not be a Business Day,
      then (notwithstanding any other provision of the Notes or this Indenture)
      payment need not be made on such date, but may be made on the next succeeding
      Business Day with the same force and effect as if made on the date on which
      nominally due, and no interest shall accrue for the period from and after any
      such nominal date.

      and all such parties hereby irrevocably agree that all claims in respect of
      such
      action or proceeding may be heard and determined in such New York State or
      federal court and hereby irrevocably waive, to the fullest extent that they
      may
      legally do so, the defense of an inconvenient forum to the maintenance of such
      action or proceeding. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES,
      TO
      THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL
      BY
      JURY IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE,

      Petition.
      The

      accepting a Note, hereby covenant and agree that they will not at any time
      prior
      to one year from the date of termination hereof, institute against the Depositor
      or the Issuing Entity, or join in any institution against the Depositor or
      the
      Issuing Entity of, any bankruptcy, reorganization, arrangement, insolvency
      or
      liquidation proceedings, or other proceedings under any United States federal

      state bankruptcy or similar law in connection with any obligations relating
      to
      the Notes, this Indenture or any of the Basic Documents, provided, however,

      claim.

     

    Section
      10.17  Inspection.
      The
      Issuing Entity agrees that, at its expense, on reasonable prior notice, it
      shall
      permit any representative of the Indenture Trustee, during the Issuing Entity’s
      normal business hours, to examine all the books of account, records, reports
      and
      other papers of the Issuing Entity, to make copies and extracts therefrom,
      to
      cause such books to be audited by Independent certified public accountants,
      and
      to discuss the Issuing Entity’s affairs, finances and accounts with the Issuing

      information except to the extent disclosure may be required by law, regulation,
      administrative or regulatory authority (and all reasonable applications for

      Indenture Trustee may reasonably determine that such disclosure is consistent
      with its obligations hereunder, provided, however, that the Indenture Trustee
      may disclose such information, on a confidential basis, to its agents, attorneys
      and auditors in connection with the performance of its responsibilities under
      this Indenture.

      respect to such Note on account of principal [and reduced by the aggregate
      amount of cumulative Realized Losses allocated to such Note on all prior Payment
      Dates, and increased by any Subsequent Recoveries allocated to such
      Note.]

     

    The
      principal of, and interest on, this Note are due and payable as described in
      the
      Indenture, in such coin or currency of the United States of America as at the
      time of payment is legal tender for payment of public and private debts. All
      payments made by the Issuing Entity with respect to this Note shall be equal
      to
      this Note’s pro rata share of the aggregate payments on all Class [__]-A-[__]
      Notes as
      described above, and shall be applied as between interest and principal as
      provided in the Indenture.

     

    All
      principal and interest accrued on the Notes, if not previously paid, will become
      finally due and payable at the Final Scheduled Payment Date.

     

    By
      acceptance of this Note, the Holder hereof agrees to surrender this Note to
      the
      Indenture Trustee promptly upon receipt of the corresponding Class of REMIC
      Notes following the occurrence of the REMIC Conversion as described in the
      Indenture.

     

    The
      Majority Certificateholder shall have the option to purchase the related assets
      of the Trust and thereby redeem the related Notes on or after the Payment Date
      on which the Stated Principal Balance of the related Mortgage Loans, and
      properties acquired in respect thereof has been reduced to less than 20% of
      the
      aggregate stated principal balance of the related Mortgage Loans as of the
      Cut-Off Date.

     

    The
      Issuing Entity shall not be liable upon the indebtedness evidenced by the Notes
      except to the extent of amounts available from the Trust Estate which
      constitutes security for the payment of the Notes. The assets included in the
      Trust Estate will be the sole source of payments on the Class [__]-A-[__]
      Notes,
      and each Holder hereof, by its acceptance of this Note, agrees that (i) such
      Note will be limited in right of payment to amounts available from the Trust
      Estate as provided in the Indenture and (ii) such Holder shall have no recourse
      to the Issuing Entity, the Owner Trustee, the Indenture Trustee, the Depositor,
      the Sponsor, the Securities Administrator, the Master Servicer, the Servicer
      or
      any of its affiliates, or to the assets of any of the foregoing entities, except
      the assets of the Issuing Entity pledged to secure the Class [__]-A-[__]
      Notes
      pursuant to the Indenture and the rights conveyed to the Issuing Entity under
      the Indenture.

     

    Any
      payment of principal or interest payable on this Note which is punctually paid
      on the applicable Payment Date shall be paid to the Person in whose name such
      Note is registered at the close of business on the Record Date for such Payment
      Date by check mailed to such person’s address as it appears in the Note Register
      on such Record Date, except for the final installment of

    principal
      and interest payable with respect to such Note, which shall be payable as
      provided below. Notwithstanding the foregoing, upon written request with
      appropriate instructions by the Holder of this Note delivered to the Indenture
      Trustee at least five Business Days prior to the Record Date, any payment of
      principal or interest, other than the final installment of principal or
      interest, shall be made by wire transfer to an account in the United States
      designated by such Holder. All reductions in the principal amount of a Note
      effected by payments of principal made on any Payment Date shall be binding
      upon
      all Holders of this Note and of any Note issued upon the registration of
      transfer thereof or in exchange therefor or in lieu thereof, whether or not
      such
      payment is noted on such Note. The final payment of this Note shall be payable
      upon presentation and surrender thereof on or after the Payment Date thereof
      at
      the office or agency designated by the Indenture Trustee and maintained by
      it
      for such purpose pursuant to Section 3.02 of the Indenture.

     

    Subject
      to the foregoing provisions, each Note delivered under the Indenture, upon
      registration of transfer of or in exchange for or in lieu of any other Note,
      shall carry the right to unpaid principal and interest that were carried by
      such
      other Note.

     

    If
      an
      Event of Default as defined in the Indenture shall occur and be continuing
      with
      respect to the Notes, the Notes may become or be declared due and payable in
      the
      manner and with the effect provided in the Indenture. If any such acceleration
      of maturity occurs prior to the payment of the entire unpaid Note Principal
      Balance of the Notes, the amount payable to the Holder of this Note will be
      equal to the sum of the unpaid Note Principal Balance of this Note, together
      with accrued and unpaid interest thereon as described in the Indenture. The
      Indenture provides that, notwithstanding the acceleration of the maturity of
      the
      Notes, under certain circumstances specified therein, all amounts collected
      as
      proceeds of the Trust Estate securing the Notes or otherwise shall continue
      to
      be applied to payments of principal of and interest on the Notes as if they
      had
      not been declared due and payable.

     

    The
      failure to pay any Unpaid Interest Shortfall at any time when funds are not
      available to make such payment as provided in the Indenture shall not constitute
      an Event of Default under the Indenture.

     

    The
      Holder of this Note or Beneficial Owner of any interest herein is deemed to
      represent that either (1) it is not acquiring the Note with Plan Assets or
      (2)
      (A) the acquisition, holding and transfer of a Note will not give rise to a
      non-exempt prohibited transaction under Section 406 of ERISA or Section 4975
      of
      the Code and (B) the Note is rated investment grade or better and such person
      believes that the Note is properly treated as indebtedness without substantial
      equity features for purposes of the DOL Regulations, and agrees to so treat
      the
      Note. Alternatively, regardless of the rating of the Note, such person may
      provide the Indenture Trustee and the Owner Trustee with an opinion of counsel,
      which opinion of counsel will not be at the expense of the Issuing Entity,
      the
      Sponsor, the Depositor, any Underwriter, the Owner Trustee, the Indenture
      Trustee, the Securities Administrator, the Master Servicer, the Servicer or
      any
      successor servicer, which opines that the acquisition, holding and transfer
      of
      such Note or interest therein is permissible under applicable law, will not
      constitute or result in a non-exempt prohibited transaction under ERISA or
      Section 4975 of the Code and will not subject the Issuing Entity, the Sponsor,
      the Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the
      Securities Administrator, the Master Servicer, the Servicer or any successor
      servicer to any obligation in addition to those undertaken in the
      Indenture.

     

    As
      provided in the Indenture and subject to certain limitations therein set forth,
      the transfer of this Note may be registered on the Note Register of the Issuing
      Entity. Upon surrender for registration of transfer of, or presentation of
      a
      written instrument of transfer for, this Note at the office or agency designated
      by the Issuing Entity pursuant to the Indenture, accompanied by proper
      instruments of assignment in form satisfactory to the Indenture Trustee, one
      or
      more new Notes of any authorized denominations and of a like aggregate then
      outstanding Note Principal Balance, will be issued to the designated transferee
      or transferees.

     

    Prior
      to
      the due presentment for registration of transfer of this Note, the Issuing
      Entity, the Indenture Trustee and any agent of the Issuing Entity or the
      Indenture Trustee may treat the Person in whose name this Note is registered
      as
      the owner of such Note (i) on the applicable Record Date for the purpose of
      making payments and interest of such Note, and (ii) on any other date for all
      other purposes whatsoever, as the owner hereof, whether or not this Note be
      overdue, and neither the Issuing Entity, the Indenture Trustee nor any such
      agent of the Issuing Entity or the Indenture Trustee shall be affected by notice
      to the contrary.

     

    The
      Indenture permits, with certain exceptions as therein provided, the amendment
      thereof and the modification of the rights and obligations of the Issuing Entity
      and the rights of the Holders of the Notes under the Indenture at any time
      by
      the Issuing Entity and the Holders of a majority of each Class of Notes affected
      thereby. The Indenture also contains provisions permitting the Holders of Notes
      representing not less than a majority of the aggregate Note Principal Balance
      of
      the Notes, to waive any past Event of Default and its consequences except an
      Event of Default (a) with respect to payment of principal of or interest on
      any
      of the Notes, or (b) in respect of a covenant or provision of the Indenture
      which cannot be modified or amended without the consent of the Holder of each
      Note. Any such waiver by the Holder, at the time of the giving thereof, of
      this
      Note (or any one or more predecessor Notes) shall bind the Holder of every
      Note
      issued upon the registration of transfer hereof or in exchange hereof or in
      lieu
      hereof, whether or not notation of such consent or waiver is made upon such
      Note. The Indenture also permits the Issuing Entity and the Indenture Trustee,
      following prior notice to the Rating Agencies, to amend or waive certain terms
      and conditions set forth in the Indenture without the consent of the Holders
      of
      the Notes issued thereunder.

     

    Initially,
      the Notes will be registered in the name of Cede & Co. as nominee of DTC,
      acting in its capacity as the Depository for the Notes. The Notes will be
      delivered by the clearing agency in denominations as provided in the Indenture
      and subject to certain limitations therein set forth. The Notes are exchangeable
      for a like aggregate then outstanding Note Principal Balance of Notes of
      different authorized denominations, as requested by the Holder surrendering
      same.

     

    Unless
      the Certificate of Authentication hereon has been executed by the Indenture
      Trustee by manual signature, this Note shall not be entitled to any benefit
      under the Indenture, or be valid or obligatory for any purpose.

     

    Anything
      herein to the contrary notwithstanding, except as expressly provided in the
      Basic Documents, neither the Owner Trustee in its individual capacity, nor
      any
      of its respective partners, beneficiaries, agents, officers, directors,
      employees, or successors or assigns, shall be personally liable for, nor shall
      recourse be had to any of them for, the payment of principal of or interest
      on,
      or performance of, or omission to perform, any of the covenants, obligations
      or
      indemnifications contained in this Note, it being expressly understood that
      said
      covenants, obligations and indemnifications have been made solely by the Trust
      to the extent of the assets of the Trust. The Holder of this Note by the
      acceptance hereof agrees that, except as expressly provided in the Basic
      Documents, the Holder shall have no claim against any of the foregoing for
      any
      deficiency, loss or claim therefrom; provided, however, that nothing contained
      herein shall be taken to prevent recourse to, and enforcement against, the
      assets of the Trust Estate for any and all liabilities, obligations and
      undertakings contained in this Note.

     

    AS
      PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS NOTE SHALL
      BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF
      NEW
      YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

    IN
      WITNESS WHEREOF, the Issuing Entity has caused this instrument to be duly
      executed by Wilmington Trust Company, not in its individual capacity but solely
      as Owner Trustee.

    American
      Home Mortgage Investment Trust 2006-1 (the “Issuing Entity”), a Delaware
      statutory trust, for value received, hereby promises to pay to [____________]
      or
      registered assigns, the principal sum of $[______________] in monthly
      installments on the twenty-fifth day of each month or, if such day is not a
      Business Day, the next succeeding Business Day (each a “Payment Date”),
      commencing in April 2006 and ending on or before the Payment Date occurring
      in
      _________________ (the “Final Scheduled Payment Date”) and to pay interest on
      the Note Principal Balance of this Note (this “Note”) outstanding from time to
      time as provided below.

     

    This
      Note
      is one of a duly authorized issue of the Issuing Entity’s Mortgage-Backed Notes,
      Series 2006-1 (the “Notes”), issued under an Indenture dated as of March 29,
      2006 (the “Indenture”), between the Issuing Entity, Deutsche Bank National Trust
      Company, as indenture trustee (the “Indenture Trustee”) and Wells Fargo Bank,
      N.A., as securities administrator (the “Securities Administrator”), to which
      Indenture and all indentures supplemental thereto reference is hereby made
      for a
      statement of the respective rights thereunder of the Issuing Entity, the
      Indenture Trustee, the Securities Administrator and the Holders of the Notes
      and
      the terms upon which the Notes are to be authenticated and delivered. All terms
      used in this Note which are defined in the Indenture shall have the meanings
      assigned to them in the Indenture.

     

    Payments
      of principal and interest on this Note will be made on each Payment Date to
      the
      Noteholder of record as of the related Record Date. The “Note Principal Balance”
of a Note as of any date of determination is equal to the initial Note Principal
      Balance thereof, reduced by the aggregate of all amounts previously paid with
      respect to such Note on account of principal and the aggregate amount of
      cumulative Realized Losses allocated to such Note on all prior Payment Dates,
      and increased by any Subsequent Recoveries allocated to such Note.

     

    The
      principal of, and interest on, this Note are due and payable as described in
      the
      Indenture, in such coin or currency of the United States of America as at the
      time of payment is legal tender for payment of public and private debts. All
      payments made by the Issuing Entity with respect to this Note shall be equal
      to
      this Note’s pro rata share of the aggregate payments on all Class [__]-M-[__]
      Notes as described above, and shall be applied as between interest and principal
      as provided in the Indenture.

     

    All
      principal and interest accrued on the Notes, if not previously paid, will become
      finally due and payable at the Final Scheduled Payment Date.

     

    By
      acceptance of this Note, the Holder hereof agrees to surrender this Note to
      the
      Indenture Trustee promptly upon receipt of the corresponding Class of REMIC
      Notes or REMIC Privately Offered Certificates, as applicable, following the
      occurrence of the REMIC Conversion as described in the Indenture.

     

    The
      Majority Certificateholder shall have the option to purchase the related assets
      of the Trust and thereby redeem the related Notes on or after the Payment Date
      on which the Stated Principal Balance of the related Mortgage Loans, and
      properties acquired in respect thereof has been reduced to less than 20% of
      the
      aggregate stated principal balance of the related Mortgage Loans as of the
      Cut-Off Date.

     

    The
      Issuing Entity shall not be liable upon the indebtedness evidenced by the Notes
      except to the extent of amounts available from the Trust Estate which
      constitutes security for the payment of the Notes. The assets included in the
      Trust Estate will be the sole source of payments on the Class [__]-M-[__] Notes,
      and each Holder hereof, by its acceptance of this Note, agrees that (i) such
      Note will be limited in right of payment to amounts available from the Trust
      Estate as provided in the Indenture and (ii) such Holder shall have no recourse
      to the Issuing Entity, the Owner Trustee, the Indenture Trustee, the Depositor,
      the Securities Administrator, the Sponsor, the Master Servicer, the Servicer
      or
      any of its affiliates, or to the assets of any of the foregoing entities, except
      the assets of the Issuing Entity pledged to secure Class [__]-M-[__] Notes
      pursuant to the Indenture and the rights conveyed to the Issuing Entity under
      the Indenture.

     

    Any
      payment of principal or interest payable on this Note which is punctually paid
      on the applicable Payment Date shall be paid to the Person in whose name such
      Note is registered at the close of business on the Record Date for such Payment
      Date by check mailed to such person’s address as it appears in the Note Register
      on such Record Date, except for the final installment of principal and interest
      payable with respect to such Note, which shall be payable as provided below.
      Notwithstanding the foregoing, upon written request with appropriate
      instructions by the Holder of this Note delivered to the Indenture Trustee
      at
      least five Business Days prior to the Record Date, any payment of principal
      or
      interest, other than the final installment of principal or interest, shall
      be
      made by wire transfer to an account in the United States designated by such
      Holder. All reductions in the principal amount of a Note effected by payments
      of
      principal made on any Payment Date shall be binding upon all Holders of this
      Note and of any note issued upon the registration of transfer thereof or in
      exchange therefor or in lieu thereof, whether or not such payment is noted
      on
      such Note. The final payment of this Note shall be payable upon presentation
      and
      surrender thereof on or after the Payment Date thereof at the office or agency
      designated by the Indenture Trustee and maintained by it for such purpose
      pursuant to Section 3.02 of the Indenture.

     

    Subject
      to the foregoing provisions, each Note delivered under the Indenture, upon
      registration of transfer of or in exchange for or in lieu of any other Note,
      shall carry the right to unpaid principal and interest that were carried by
      such
      other Note.

     

    If
      an
      Event of Default as defined in the Indenture shall occur and be continuing
      with
      respect to the Notes, the Notes may become or be declared due and payable in
      the
      manner and with the effect provided in the Indenture. If any such acceleration
      of maturity occurs prior to the payment of the entire unpaid Note Principal
      Balance of the Notes, the amount payable to the Holder of this Note will be
      equal to the sum of the unpaid Note Principal Balance of this Note, together
      with accrued and unpaid interest thereon as described in the Indenture. The
      Indenture provides that, notwithstanding the acceleration of the maturity of
      the
      Notes, under certain circumstances specified therein, all amounts collected
      as
      proceeds of the Trust Estate securing the Notes or otherwise shall continue
      to
      be applied to payments of principal of and interest on the Notes as if they
      had
      not been declared due and payable.

     

    The
      failure to pay any Unpaid Interest Shortfall at any time when funds are not
      available to make such payment as provided in the Indenture shall not constitute
      an Event of Default under the Indenture.

     

    [For
      Offered Notes] [The Holder of this Note or Beneficial Owner of any interest
      herein is deemed to represent that either (1) it is not acquiring the Note
      with
      Plan Assets or (2) (A) the acquisition, holding and transfer of a Note will
      not
      give rise to a non-exempt prohibited transaction under Section 406 of ERISA
      or
      Section 4975 of the Code and (B) the Note is rated investment grade or better
      and such person believes that the Note is properly treated as indebtedness
      without substantial equity features for purposes of the DOL Regulations, and
      agrees to so treat the Note. Alternatively, regardless of the rating of the
      Note, such person may provide the Indenture Trustee and the Owner Trustee with
      an opinion of counsel, which opinion of counsel will not be at the expense
      of
      the Issuing Entity, the Sponsor, the Depositor, any Underwriter, the Owner
      Trustee, the Indenture Trustee, the Securities Administrator, the Master
      Servicer, the Servicer of any successor servicer, which opines that the
      acquisition, holding and transfer of such Note or interest therein is
      permissible under applicable law, will not constitute or result in a non-exempt
      prohibited transaction under ERISA or Section 4975 of the Code and will not
      subject the Issuing Entity, the Sponsor, the Depositor, any Underwriter, the
      Owner Trustee, the Indenture Trustee, the Securities Administrator, the Master
      Servicer, the Servicer or any successor servicer to any obligation in addition
      to those undertaken in the Indenture.]

     

    As
      provided in the Indenture and subject to certain limitations therein set forth,
      the transfer of this Note may be registered on the Note Register of the Issuing
      Entity. Upon surrender for registration of transfer of, or presentation of
      a
      written instrument of transfer for, this Note at the office or agency designated
      by the Issuing Entity pursuant to the Indenture, accompanied by proper
      instruments of assignment in form satisfactory to the Indenture Trustee, one
      or
      more new Notes of any authorized denominations and of a like aggregate then
      outstanding Note Principal Balance, will be issued to the designated transferee
      or transferees.

     

    Prior
      to
      the due presentment for registration of transfer of this Note, the Issuing
      Entity, the Indenture Trustee and any agent of the Issuing Entity or the
      Indenture Trustee may treat the Person in whose name this Note is registered
      as
      the owner of such Note (i) on the applicable Record Date for the purpose of
      making payments and interest of such Note, and (ii) on any other date for all
      other purposes whatsoever, as the owner hereof, whether or not this Note be
      overdue, and neither the Issuing Entity, the Indenture Trustee nor any such
      agent of the Issuing Entity or the Indenture Trustee shall be affected by notice
      to the contrary.

     

    The
      Indenture permits, with certain exceptions as therein provided, the amendment
      thereof and the modification of the rights and obligations of the Issuing Entity
      and the rights of the Holders of the Notes under the Indenture at any time
      by
      the Issuing Entity and the Holders of a majority of each Class of Notes affected
      thereby. The Indenture also contains provisions permitting the Holders of Notes
      representing not less than a majority of the aggregate Note Principal Balance
      of
      the Notes, to waive any past Event of Default and its consequences except an
      Event of Default (a) with respect to payment of principal of or interest on
      any
      of the Notes, or (b) in respect of a covenant or provision of the Indenture
      which cannot be modified or amended without the consent of the Holder of each
      Note. Any such waiver by the Holder, at the time of the giving thereof, of
      this
      Note (or any one or more predecessor Notes) shall bind the Holder of every
      Note
      issued upon the registration of transfer hereof or in exchange hereof or in
      lieu
      hereof, whether or not notation of such consent or waiver is made upon such
      Note. The Indenture also permits the Issuing Entity and the Indenture Trustee,
      following prior notice to the Rating Agencies, to amend or waive certain terms
      and conditions set forth in the Indenture without the consent of the Holders
      of
      the Notes issued thereunder.

     

    [Initially,
      the Notes will be registered in the name of ____________- ] [Initially, the
      Notes will be registered in the name of Cede & Co. as nominee of DTC, acting
      in its capacity as the Depository for the Notes. The Notes will be delivered
      by
      the clearing agency in denominations as provided in the Indenture and subject
      to
      certain limitations therein set forth.] The Notes are exchangeable for a like
      aggregate then outstanding Note Principal Balance of Notes of different
      authorized denominations, as requested by the Holder surrendering
      same.

     

    [No
      transfer, sale, pledge or other disposition of a Non-Offered Note shall be
      made
      unless such transfer, sale, pledge or other disposition is exempt from the
      registration requirements of the Securities Act and any applicable state
      securities laws or is made in accordance with said Act and laws. In the event
      of
      any such transfer, the Note Registrar or the Depositor shall prior to such
      transfer require the transferee to execute (A) either (i) (a) an investment
      letter in substantially the form attached to the Indenture as Exhibit K (or
      in
      such form and substance reasonably satisfactory to the Note Registrar and the
      Depositor) which investment letter shall not be an expense of the Trust, the
      Owner Trustee, the Indenture Trustee, the Securities Administrator, the Note
      Registrar, the Master Servicer, the Servicer, the Sponsor or the Depositor
      and
      which investment letter states that, among other things, such transferee (1)
      is
      a “qualified institutional buyer” as defined under Rule 144A, acting for its own
      account or the accounts of other “qualified institutional buyers” as defined
      under Rule 144A, and (2) is aware that the proposed transferor intends to rely
      on the exemption from registration requirements under the Securities Act of
      1933, as amended, provided by Rule 144A or (ii) (a) a written Opinion of Counsel
      acceptable to and in form and substance satisfactory to the Note Registrar
      and
      the Depositor that such transfer may be made pursuant to an exemption,
      describing the applicable exemption and the basis therefor, from said Act and
      laws or is being made pursuant to said Act and laws, which Opinion of Counsel
      shall not be an expense of the Trust, the Owner Trustee, the Indenture Trustee,
      the Securities Administrator, the Note Registrar, the Master Servicer, the
      Servicer, the Sponsor or the Depositor and (b) either (1) the transferee
      executes a representation letter, substantially in the form of Exhibit M hereto,
      and the transferor executes a representation letter, substantially in the form
      of Exhibit N hereto, each acceptable to and in form and substance satisfactory
      to the Note Registrar certifying the facts surrounding such transfer, which
      representation letters shall not be an expense of the Trust, the Owner Trustee,
      the Indenture Trustee, the Securities Administrator, the Note Registrar, the
      Master Servicer, the Servicer, the Sponsor or the Depositor or (2) an Opinion
      of
      Counsel has been rendered by nationally recognized tax counsel stating that
      such
      Notes will be treated as debt for federal income tax purposes and (B) the
      Certificate of Non-Foreign Status (in substantially the form attached to the
      Indenture as Exhibit L) acceptable to and in form and substance reasonably
      satisfactory to the Note Registrar, which certificate shall not be an expense
      of
      the Trust, the Owner Trustee, the Indenture Trustee, the Securities
      Administrator, the Note Registrar, the Master Servicer, the Servicer, the
      Sponsor or the Depositor. The Holder of a Non-Offered Note desiring to effect
      such transfer shall, and does hereby agree to, indemnify the Trust, the Owner
      Trustee, the Indenture Trustee, the Paying Agent, the Note Registrar, the Master
      Servicer, the Servicer 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.

     

    [For
      Non-Offered Notes] No transfer of Non-Offered Notes or any interest therein
      shall be made to any Person unless the Depositor, the Owner Trustee, the
      Securities Administrator, the Note Registrar, the Master Servicer, the Servicer
      and the Sponsor are provided with an Opinion of Counsel which establishes to
      the
      satisfaction of the Depositor, the Owner Trustee, the Indenture Trustee and
      the
      Note Registrar that the purchase of Non-Offered Notes is permissible under
      applicable law, will not constitute or result in any prohibited transaction
      under ERISA or Section 4975 of the Code and will not subject the Depositor,
      the
      Owner Trustee, the Indenture Trustee, the Securities Administrator, the Note
      Registrar, the Master Servicer, the Servicer or the Sponsor to any obligation
      or
      liability (including obligations or liabilities under ERISA or Section 4975
      of
      the Code) in addition to those undertaken in the Indenture, which Opinion of
      Counsel shall not be an expense of the Depositor, the Owner Trustee, the
      Indenture Trustee, the Securities Administrator, the Note Registrar, the Master
      Servicer, the Servicer or the Sponsor. In lieu of such Opinion of Counsel,
      a
      Person may provide a certification in the form of Exhibit G to the Indenture,
      which the Depositor, the Owner Trustee, the Indenture Trustee, the Securities
      Administrator, the Note Registrar, the Master Servicer, the Servicer and the
      Sponsor may rely upon without further inquiry or investigation. Neither an
      Opinion of Counsel nor a certification will be required in connection with
      the
      initial transfer of any such Note by the Depositor to an affiliate of the
      Depositor (in which case, the Depositor or any affiliate thereof shall have
      deemed to have represented that such affiliate is not a Plan or a Person
      investing Plan Assets) and the Owner Trustee shall be entitled to conclusively
      rely upon a representation (which, upon the request of the Owner Trustee, shall
      be a written representation) from the Depositor of the status of such transferee
      as an affiliate of the Depositor.

     

    No
      person
      shall become a Holder of Non-Offered Notes, so long as any Notes are
      Outstanding, until it shall establish its status as a real estate investment
      trust (“REIT”) or as a “qualified REIT subsidiary” (“QRS”) within the meaning of
      Section 856(a) or Section 856(i) of the Code, respectively, by submitting to
      the
      Note Registrar and the Transferee Certificate set forth in Exhibit H to the
      Indenture [for Non-Offered Notes] [, and following such transfer, such Holder
      of
      the Non-Offered Notes shall own 100% of the Non-Offered Notes and the Trust
      Certificates].

     

    No
      offer,
      sale, transfer, pledge, hypothecation or other disposition (including any
      pledge, sale or transfer under a repurchase transaction or securities loan)
      of
      any Non-Offered Note shall be made to any transferee unless, prior to such
      disposition, the proposed transferor delivers to the Note Registrar (i) an
      Opinion of Counsel, rendered by a law firm generally recognized to be qualified
      to opine concerning the tax aspects of asset securitization, to the effect
      that
      such transfer (including any disposition permitted following any default under
      any pledge or repurchase transaction) will not cause the Trust to be no longer
      be treated for federal income tax purposes as a “qualified REIT subsidiary”
within the meaning of Section 856(i) of the Code and (ii) a certificate that
      stating that any Non-Offered Notes may be transferred by the related lender
      under any such related loan agreement or repurchase agreement upon a default
      under any such indebtedness, in which case the transferor shall deliver to
      the
      Note Registrar and the Indenture Trustee substantially in the form attached
      as
      Exhibit I to the Indenture certifying to such effect. Notwithstanding the
      foregoing, the provisions of this paragraph shall not apply to the initial
      transfer of the Non-Offered Notes to the Depositor.]

     

    Unless
      the Certificate of Authentication hereon has been executed by the Indenture
      Trustee by manual signature, this Note shall not be entitled to any benefit
      under the Indenture, or be valid or obligatory for any purpose.

     

    Anything
      herein to the contrary notwithstanding, except as expressly provided in the
      Basic Documents, neither the Owner Trustee in its individual capacity, nor
      any
      of its respective partners, beneficiaries, agents, officers, directors,
      employees, or successors or assigns, shall be personally liable for, nor shall
      recourse be had to any of them for, the payment of principal of or interest
      on,
      or performance of, or omission to perform, any of the covenants, obligations
      or
      indemnifications contained in this Note, it being expressly understood that
      said
      covenants, obligations and indemnifications have been made solely by the Trust
      to the extent of the assets of the Trust. The Holder of this Note by the
      acceptance hereof agrees that, except as expressly provided in the Basic
      Documents, the Holder shall have no claim against any of the foregoing for
      any
      deficiency, loss or claim therefrom; provided, however, that nothing contained
      herein shall be taken to prevent recourse to, and enforcement against, the
      assets of the Trust Estate for any and all liabilities, obligations and
      undertakings contained in this Note.

     

    AS
      PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS NOTE SHALL
      BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF
      NEW
      YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    IN

      executed by Wilmington Trust Company, not in its individual capacity but solely
      as Owner Trustee.

    American
      Home Mortgage Investment Trust 2006-1 (the “Issuing Entity”), a Delaware
      statutory trust, for value received, hereby promises to pay to [____________]
      or
      registered assigns, the principal sum of $[______________] in monthly
      installments on the twenty-fifth day of each month or, if such day is not a
      Business Day, the next succeeding Business Day (each a “Payment Date”),
      commencing in April 2006 and ending on or before the Payment Date occurring
      in
      ______________ (the “Final Scheduled Payment Date”) [and to pay interest on the
      Note Principal Balance of this Note (this “Note”) outstanding from time to time
      as provided below.]

     

    This
      Note
      is one of a duly authorized issue of the Issuing Entity’s Mortgage-Backed Notes,
      Series 2006-1 (the “Notes”), issued under an Indenture dated as of March 29,
      2006 (the “Indenture”), between the Issuing Entity, Deutsche Bank National Trust
      Company, as indenture trustee (the “Indenture Trustee”) and Wells Fargo Bank,
      N.A., as securities administrator (the “Securities Administrator”), to which
      Indenture and all indentures supplemental thereto reference is hereby made
      for a
      statement of the respective rights thereunder of the Issuing Entity, the
      Indenture Trustee and the Holders of the Notes and the terms upon which the
      Notes are to be authenticated and delivered. All terms used in this Note which
      are defined in the Indenture shall have the meanings assigned to them in the
      Indenture.

     

    Payments
      of principal on this Note will be made on each Payment Date to the Noteholder
      of
      record as of the related Record Date. The “Note Principal Balance” of a Note as
      of any date of determination is equal to the initial Note Principal Balance
      thereof, reduced by the aggregate of all amounts previously paid with respect
      to
      such Note on account of principal and the aggregate amount of cumulative
      Realized Losses allocated to such Note on all prior Payment Dates, and increased
      by any Subsequent Recoveries allocated to such Note.

     

    The
      principal of this Note is due and payable as described in the Indenture, in
      such
      coin or currency of the United States of America as at the time of payment
      is
      legal tender for payment of public and private debts. All payments made by
      the
      Issuing Entity with respect to this Note shall be equal to this Note’s pro rata
      share of the aggregate payments on all Class II-B Notes
      as
      described above, and shall be applied as principal as provided in the
      Indenture.

     

    All
      principal on the Notes, if not previously paid, will become finally due and
      payable at the Final Scheduled Payment Date.

     

    By
      acceptance of this Note, the Holder hereof agrees to surrender this Note to
      the
      Indenture Trustee promptly upon receipt of the corresponding Class of REMIC
      Privately Offered Certificates following the occurrence of the REMIC Conversion
      as described in the Indenture.

     

    The
      Majority Certificateholder shall have the option to purchase the related assets
      of the Trust and thereby redeem the related Notes on or after the Payment Date
      on which the Stated Principal Balance of the related Mortgage Loans, and
      properties acquired in respect thereof has been reduced to less than 10% of
      the
      aggregate stated principal balance of the related Mortgage Loans as of the
      Cut-Off Date.

     

    The
      Issuing Entity shall not be liable upon the indebtedness evidenced by the Notes
      except to the extent of amounts available from the Trust Estate which
      constitutes security for the payment of the Notes. The assets included in the
      Trust Estate will be the sole source of payments on the Class II-B Notes,
      and each Holder hereof, by its acceptance of this Note, agrees that (i) such
      Note will be limited in right of payment to amounts available from the Trust
      Estate as provided in the Indenture and (ii) such Holder shall have no recourse
      to the Issuing Entity, the Owner Trustee, the Indenture Trustee, the Depositor,
      the Securities Administrator, the Sponsor, the Master Servicer, Servicer or
      any
      of its affiliates, or to the assets of any of the foregoing entities, except
      the
      assets of the Issuing Entity pledged to secure the Class II-B Notes
      pursuant to the Indenture and the rights conveyed to the Issuing Entity under
      the Indenture.

     

    Any
      payment of principal payable on this Note which is punctually paid on the
      applicable Payment Date shall be paid to the Person in whose name such Note
      is
      registered at the close of business on the Record Date for such Payment Date
      by
      check mailed to such person’s address as it appears in the Note Register on such
      Record Date, except for the final installment of principal payable with respect
      to such Note, which shall be payable as provided below. Notwithstanding the
      foregoing, upon written request with appropriate instructions by the Holder
      of
      this Note delivered to the Indenture Trustee at least five Business Days prior
      to the Record Date, any payment of principal, other than the final installment
      of principal, shall be made by wire transfer to an account in the United States
      designated by such Holder. All reductions in the principal amount of a Note
      effected by payments of principal made on any Payment Date shall be binding
      upon
      all Holders of this Note and of any note issued upon the registration of
      transfer thereof or in exchange therefor or in lieu thereof, whether or not
      such
      payment is noted on such Note. The final payment of this Note shall be payable
      upon presentation and surrender thereof on or after the Payment Date thereof
      at
      the office or agency designated by the Indenture Trustee and maintained by
      it
      for such purpose pursuant to Section 3.02 of the Indenture.

     

    Subject
      to the foregoing provisions, each Note delivered under the Indenture, upon
      registration of transfer of or in exchange for or in lieu of any other Note,
      shall carry the right to unpaid principal that was carried by such other
      Note.

     

    If
      an
      Event of Default as defined in the Indenture shall occur and be continuing
      with
      respect to the Notes, the Notes may become or be declared due and payable in
      the
      manner and with the effect provided in the Indenture. If any such acceleration
      of maturity occurs prior to the payment of the entire unpaid Note Principal
      Balance of the Notes, the amount payable to the Holder of this Note will be
      equal to the sum of the unpaid Note Principal Balance of this Note. The
      Indenture provides that, notwithstanding the acceleration of the maturity of
      the
      Notes, under certain circumstances specified therein, all amounts collected
      as
      proceeds of the Trust Estate securing the Notes or otherwise shall continue
      to
      be applied to payments of principal of the Notes as if they had not been
      declared due and payable.

     

    As
      provided in the Indenture and subject to certain limitations therein set forth,
      the transfer of this Note may be registered on the Note Register of the Issuing
      Entity. Upon surrender for registration of transfer of, or presentation of
      a
      written instrument of transfer for, this Note at the office or agency designated
      by the Issuing Entity pursuant to the Indenture, accompanied by proper
      instruments of assignment in form satisfactory to the Indenture Trustee, one
      or
      more new Notes of any authorized denominations and of a like aggregate then
      outstanding Note Principal Balance, will be issued to the designated transferee
      or transferees.

     

    Prior
      to
      the due presentment for registration of transfer of this Note, the Issuing
      Entity, the Indenture Trustee and any agent of the Issuing Entity or the
      Indenture Trustee may treat the Person in whose name this Note is registered
      as
      the owner of such Note (i) on the applicable Record Date for the purpose of
      making payments of such Note, and (ii) on any other date for all other purposes
      whatsoever, as the owner hereof, whether or not this Note be overdue, and
      neither the Issuing Entity, the Indenture Trustee nor any such agent of the
      Issuing Entity or the Indenture Trustee shall be affected by notice to the
      contrary.

     

    The
      Indenture permits, with certain exceptions as therein provided, the amendment
      thereof and the modification of the rights and obligations of the Issuing Entity
      and the rights of the Holders of the Notes under the Indenture at any time
      by
      the Issuing Entity and the Holders of a majority of each Class of Notes affected
      thereby. The Indenture also contains provisions permitting the Holders of Notes
      representing not less than a majority of the aggregate Note Principal Balance
      of
      the Notes, to waive any past Event of Default and its consequences except an
      Event of Default (a) with respect to payment of principal of on any of the
      Notes, or (b) in respect of a covenant or provision of the Indenture which
      cannot be modified or amended without the consent of the Holder of each Note.
      Any such waiver by the Holder, at the time of the giving thereof, of this Note
      (or any one or more predecessor Notes) shall bind the Holder of every Note
      issued upon the registration of transfer hereof or in exchange hereof or in
      lieu
      hereof, whether or not notation of such consent or waiver is made upon such
      Note. The Indenture also permits the Issuing Entity and the Indenture Trustee,
      following prior notice to the Rating Agencies, to amend or waive certain terms
      and conditions set forth in the Indenture without the consent of the Holders
      of
      the Notes issued thereunder.

     

    Initially,
      the Notes will be registered in the name of ____________. The Notes are
      exchangeable for a like aggregate then outstanding Note Principal Balance of
      Notes of different authorized denominations, as requested by the Holder
      surrendering same.

     

    No
      transfer, sale, pledge or other disposition of a Non-Offered Note shall be
      made
      unless such transfer, sale, pledge or other disposition is exempt from the
      registration requirements of the Securities Act and any applicable state
      securities laws or is made in accordance with said Act and laws. In the event
      of
      any such transfer, the Note Registrar or the Depositor shall prior to such
      transfer require the transferee to execute (A) either (i) (a) an investment
      letter in substantially the form attached to the Indenture as Exhibit K (or
      in
      such form and substance reasonably satisfactory to the Note Registrar and the
      Depositor) which investment letter shall not be an expense of the Trust, the
      Owner Trustee, the Indenture Trustee, the Securities Administrator, the Note
      Registrar, the Master Servicer, the Servicer, the Sponsor or the Depositor
      and
      which investment letter states that, among other things, such transferee (1)
      is
      a “qualified institutional buyer” as defined under Rule 144A, acting for its own
      account or the accounts of other “qualified institutional buyers” as defined
      under Rule 144A, and (2) is aware that the proposed transferor intends to rely
      on the exemption from registration requirements under the Securities Act of
      1933, as amended, provided by Rule 144A or (ii) (a) a written Opinion of Counsel
      acceptable to and in form and substance satisfactory to the Note Registrar
      and
      the Depositor that such transfer may be made pursuant to an exemption,
      describing the applicable exemption and the basis therefor, from said Act and
      laws or is being made pursuant to said Act and laws, which Opinion of Counsel
      shall not be an expense of the Trust, the Owner Trustee, the Indenture Trustee,
      the Securities Administrator, the Note Registrar, the Master Servicer, the
      Servicer, the Sponsor or the Depositor and (b) either (1) the transferee
      executes a representation letter, substantially in the form of Exhibit M hereto,
      and the transferor executes a representation letter, substantially in the form
      of Exhibit N hereto, each acceptable to and in form and substance satisfactory
      to the Note Registrar certifying the facts surrounding such transfer, which
      representation letters shall not be an expense of the Trust, the Owner Trustee,
      the Indenture Trustee, the Securities Administrator, the Note Registrar, the
      Master Servicer, the Servicer, the Sponsor or the Depositor or (2) an Opinion
      of
      Counsel has been rendered by nationally recognized tax counsel stating that
      such
      Notes will be treated as debt for federal income tax purposes and (B) the
      Certificate of Non-Foreign Status (in substantially the form attached to the
      Indenture as Exhibit L) acceptable to and in form and substance reasonably
      satisfactory to the Note Registrar, which certificate shall not be an expense
      of
      the Trust, the Owner Trustee, the Indenture Trustee, the Securities
      Administrator, the Note Registrar, the Master Servicer, the Servicer, the
      Sponsor or the Depositor. The Holder of a Non-Offered Note desiring to effect
      such transfer shall, and does hereby agree to, indemnify the Trust, the Owner
      Trustee, the Indenture Trustee, the Paying Agent, the Note Registrar, the Master
      Servicer, the Servicer 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.

     

    No
      transfer of Non-Offered Notes or any interest therein shall be made to any
      Person unless the Depositor, the Owner Trustee, the Securities Administrator,
      the Note Registrar, the Master Servicer, the Servicer and the Sponsor are
      provided with an Opinion of Counsel which establishes to the satisfaction of
      the
      Depositor, the Owner Trustee, the Indenture Trustee and the Note Registrar
      that
      the purchase of Non-Offered Notes is permissible under applicable law, will
      not
      constitute or result in any prohibited transaction under ERISA or Section 4975
      of the Code and will not subject the Depositor, the Owner Trustee, the Indenture
      Trustee, the Securities Administrator, the Note Registrar, the Master Servicer,
      the Servicer or the Sponsor to any obligation or liability (including
      obligations or liabilities under ERISA or Section 4975 of the Code) in addition
      to those undertaken in the Indenture, which Opinion of Counsel shall not be
      an
      expense of the Depositor, the Owner Trustee, the Indenture Trustee, the
      Securities Administrator, the Note Registrar, the Master Servicer, the Servicer
      or the Sponsor. In lieu of such Opinion of Counsel, a Person may provide a
      certification in the form of Exhibit G to the Indenture, which the Depositor,
      the Owner Trustee, the Indenture Trustee, the Securities Administrator, the
      Note
      Registrar, the Master Servicer, the Servicer and the Sponsor may rely upon
      without further inquiry or investigation. Neither an Opinion of Counsel nor
      a
      certification will be required in connection with the initial transfer of any
      such Note by the Depositor to an affiliate of the Depositor (in which case,
      the
      Depositor or any affiliate thereof shall have deemed to have represented that
      such affiliate is not a Plan or a Person investing Plan Assets) and the Owner
      Trustee shall be entitled to conclusively rely upon a representation (which,
      upon the request of the Owner Trustee, shall be a written representation) from
      the Depositor of the status of such transferee as an affiliate of the
      Depositor.

     

    No
      person
      shall become a Holder of Non-Offered Notes, so long as any Notes are
      Outstanding, until it shall establish its status as a real estate investment
      trust (“REIT”) or as a “qualified REIT subsidiary” (“QRS”) within the meaning of
      Section 856(a) or Section 856(i) of the Code, respectively, by submitting to
      the
      Note Registrar and the Owner Trustee and the Transferee Certificate set forth
      in
      Exhibit H to the Indenture, and following such transfer, such Holder of
      Non-Offered Notes shall own 100% of the Non-Offered Notes and the Trust
      Certificates.

     

    No
      offer,
      sale, transfer, pledge, hypothecation or other disposition (including any
      pledge, sale or transfer under a repurchase transaction or securities loan)
      of
      any Non-Offered Note shall be made to any transferee unless, prior to such
      disposition, the proposed transferor delivers to the Note Registrar (i) an
      Opinion of Counsel, rendered by a law firm generally recognized to be qualified
      to opine concerning the tax aspects of asset securitization, to the effect
      that
      such transfer (including any disposition permitted following any default under
      any pledge or repurchase transaction) will not cause the Trust to be no longer
      be treated for federal income tax purposes as a “qualified REIT subsidiary”
within the meaning of Section 856(i) of the Code and (ii) a certificate that
      stating that any Non-Offered Notes may be transferred by the related lender
      under any such related loan agreement or repurchase agreement upon a default
      under any such indebtedness, in which case the transferor shall deliver to
      the
      Note Registrar, the Owner Trustee and the Indenture Trustee substantially in
      the
      form attached as Exhibit I to the Indenture certifying to such effect.
      Notwithstanding the foregoing, the provisions of this paragraph shall not apply
      to the initial transfer of the Non-Offered Notes to the Depositor.

     

    Unless
      the Certificate of Authentication hereon has been executed by the Indenture
      Trustee by manual signature, this Note shall not be entitled to any benefit
      under the Indenture, or be valid or obligatory for any purpose.

     

    Anything
      herein to the contrary notwithstanding, except as expressly provided in the
      Basic Documents, neither the Owner Trustee in its individual capacity, nor
      any
      of its respective partners, beneficiaries, agents, officers, directors,
      employees, or successors or assigns, shall be personally liable for, nor shall
      recourse be had to any of them for, the payment of principal of [or interest
      on,] or performance of, or omission to perform, any of the covenants,
      obligations or indemnifications contained in this Note, it being expressly
      understood that said covenants, obligations and indemnifications have been
      made
      solely by the Trust to the extent of the assets of the Trust. The Holder of
      this
      Note by the acceptance hereof agrees that, except as expressly provided in
      the
      Basic Documents, the Holder shall have no claim against any of the foregoing
      for
      any deficiency, loss or claim therefrom; provided, however, that nothing
      contained herein shall be taken to prevent recourse to, and enforcement against,
      the assets of the Trust Estate for any and all liabilities, obligations and
      undertakings contained in this Note.

     

    AS
      PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS NOTE SHALL
      BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF
      NEW

      respect to any Mortgage File if no such documents appear in the Mortgage File
      delivered to the Indenture Trustee.

      the Rule 144A Securities described above to the undersigned buyer (the
“Buyer”).

     

    1.
      In
      connection with such transfer and in accordance with the agreements pursuant
      to
      which the Rule 144A Securities were issued, the Sponsor hereby certifies the
      following facts: Neither the Sponsor nor anyone acting on its behalf has
      offered, transferred, pledged, sold or otherwise disposed of the Rule 144A
      Securities, any interest in the Rule 144A Securities or any other similar

      or
      made any general solicitation by means of general advertising or in any other

      the
      Rule 144A Securities under the Securities Act of 1933, as amended (the “1933
      Act”), or that would render the disposition of the Rule 144A Securities a
      violation of Section 5 of the 1933 Act or require registration pursuant thereto,
      and that the Sponsor has not offered the Rule 144A Securities to any person
      other than the Buyer or another “qualified institutional buyer” as defined in
      Rule 144A under the 1933 Act.

    a.
      The
      Buyer understands that the Rule 144A Securities have not been registered under
      the 1933 Act or the securities laws of any state.

     

    b.
      The
      Buyer considers itself a substantial, sophisticated institutional investor
      having such knowledge and experience in financial and business matters that

      Securities.

     

    c.

      security with, any person in any manner, or made any general solicitation by
      means of general advertising or in any other manner, or taken any other action,
      that would constitute a distribution of the Rule 144A Securities under the
      1933
      Act or that would render the disposition of the Rule 144A Securities a violation
      of Section 5 of the 1933 Act or require registration pursuant thereto, nor
      will
      it act, nor has it authorized or will it authorize any person to act, in such
      manner with respect to the Rule 144A Securities.

     

    e.
      The
      Buyer is a “qualified institutional buyer” as that term is defined in Rule 144A
      under the 1933 Act and has completed either of the forms of certification to
      that effect attached hereto as Annex 1 or Annex 2. The Buyer is aware that
      the
      sale to it is being made in reliance on Rule 144A. The Buyer is acquiring the
      Rule 144A Securities for its own account or the accounts of other qualified
      institutional buyers, understands that such Rule 144A Securities may be resold,
      pledged or transferred only (i) to a person reasonably believed to be a

      account of a qualified institutional buyer to whom notice is given that the
      resale, pledge or transfer is being made in reliance on Rule 144A, or (ii)
      pursuant to another exemption from registration under the 1933 Act.

      Buyer warrants and represents to, and covenants with, the Sponsor, the Indenture
      Trustee, the Owner Trustee, the Note Registrar, the Master Servicer, the

      Buyer is (A) not an employee benefit plan (within the meaning of Section 3(3)
      of
      the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), or a
      plan (within the meaning of Section 4975(e)(1) of the Internal Revenue Code
      of
      1986 (“Code”)), which (in either case) is subject to ERISA or Section 4975 of
      the Code (each, a “Plan”), and (B) is not directly or indirectly purchasing the
      Rule 144A Securities on behalf of, as investment manager of, as named fiduciary

      that registration of transfer of any Rule 144A Securities to any Plan, or to
      any
      Person acting on behalf of any Plan, will not be made unless such Plan delivers
      an opinion of its counsel, addressed and satisfactory to the Owner Trustee,
      Indenture Trustee, Note Registrar and the Depositor, to the effect (A) that
      the
      purchase and holding of the Rule 144A Securities by, on behalf of or with “plan
      assets” of any Plan, (B) operation of the Trust and (C) management of Trust
      assets are permissible under applicable law, would not constitute or result
      in a
      prohibited transaction under ERISA or Section 4975 of the Code, and would not
      subject the Depositor, the Sponsor, the Owner Trustee, the Indenture Trustee,
      the Note Registrar, the Securities Administrator, the Master Servicer or the
      Servicer to any obligation or liability (including liabilities under ERISA
      or
      Section 4975 of the Code) in addition to those undertaken in the Agreement,
      which Opinion of Counsel shall not be an expense of the Depositor, the Sponsor,

                The Buyer is a trust fund whose trustee is a bank or trust company
                and
                whose participants are exclusively (a) plans established and maintained
                by
                a State, its political subdivisions, or any agency or instrumentality
                of
                the State or its political subdivisions, for the benefit of its employees,
                or (b) employee benefit plans within the meaning of Title I of the
                Employee Retirement Income Security Act of 1974, but is not a trust
                fund
                that includes as participants individual retirement accounts or H.R.
                10
                plans.

            

    

     

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

     

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

     

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

     

    
      	
              _____      
                _____           
                Will the Buyer be purchasing the Rule 144A

              Yes  
                No  Securities
                only for the Buyer's own account?

            

    

    

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

     

    7.
      The
      Buyer will notify each of the parties to which this certification is made of
      any
      changes in the information and conclusions herein. Until such notice is given,
      the Buyer's purchase of Rule 144A Securities will constitute a reaffirmation
      of
      this certification as of the date of such purchase.

    1.
      As

    2.
      In
      connection with purchases by Buyer, the Buyer is a “qualified institutional

      least $100,000,000 in securities (other than the excluded securities referred
      to
      below) as of the end of the Buyer's most recent fiscal year. For purposes of
      determining the amount of securities owned by the Buyer or the Buyer's Family

      accordance with Rule 144A).

     

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

     

    4.
      The
      term “securities”

      own account.

     

    6.

      undersigned will notify each of the parties to which this certification is
      made
      of any changes in the information and conclusions herein. Until such notice,

      certify that (a) we understand that the Non-Offered Notes 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 Non-Offered
      Notes, (c) we have had the opportunity to ask questions of and receive answers
      from the Depositor concerning the purchase of the Non-Offered Notes and all
      matters relating thereto or any additional information deemed necessary to
      our
      decision to purchase the Non-Offered Notes, (d) we are not an employee benefit
      plan that is subject to the Employee Retirement Income Security Act of 1974,
      as
      amended, or a plan 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, (e) we are
      acquiring the Non-Offered Notes for investment for our own account and not
      with
      a view to any distribution of such Non-Offered Notes (but without prejudice
      to
      our right at all times to sell or otherwise dispose of the Non-Offered Notes
      in
      accordance with clause (g) below), (f) we have not offered or sold any
      Non-Offered Notes to, or solicited offers to buy any Non-Offered Notes 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, and (g) we will not sell, transfer or otherwise dispose of any
      Non-Offered Notes 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 Non-Offered Note 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

      connection with the proposed Transfer to _____________________ (the
“Transferee”) of a non-offered note, Class [___] (the “Non-Offered Note”)
      representing ___% fractional undivided interest in American Home Mortgage
      Investment Trust 2006-1 (the “Trust”), issued pursuant to an Indenture, dated as
      of March 29, 2006 (the “Indenture”), among American Home Mortgage Investment
      Trust 2006-1, (the “Issuing Entity”), Deutsche Bank National Trust Company, as
      Indenture Trustee (the “Indenture Trustee”), and Wells Fargo Bank, N.A., as
      Securities Administrator (the “Securities Administrator”). Initially capitalized
      terms used but not defined herein have the meanings assigned to them in Appendix
      A to the Indenture. The Transferor hereby certifies, represents and warrants
      to,
      and covenants with, the Company, the Owner Trustee and the Note Registrar
      that:

     

    Neither
      the Transferor nor anyone acting on its behalf has (a) offered, pledged, sold,
      disposed of or otherwise transferred any Non-Offered Note, any interest in
      any
      Non-Offered Note or any other similar security to any person in any manner,
      (b)
      has solicited any offer to buy or to accept a pledge, disposition or other
      transfer of any Non-Offered Note, any interest in any Non-Offered Note or any
      other similar security from any person in any manner, (c) has otherwise
      approached or negotiated with respect to any Non-Offered Note, any interest
      in
      any Non-Offered Note or any other similar security with any person in any
      manner, (d) has made any general solicitation by means of general advertising
      or
      in any other manner, or (e) has taken any other action, that (as to any of
      (a)
      through (e) above) would constitute a distribution of the Non-Offered Notes
      under the Securities Act of 1933 (the “Act”), that would render the disposition
      of any Non-Offered Note a violation of Section 5 of the Act or any state
      securities law, or that would require registration or qualification pursuant
      thereto. The Transferor will not act in any manner set forth in the foregoing
      sentence with respect to any Non-Offered Note. The Transferor has not and will
      not sell or otherwise transfer any of the Non-Offered Notes, except in
      compliance with the provisions of the Indenture.

    APPENDIX
      A

    DEFINITIONS

     

    Accepted
      Master Servicing Practices:
      With
      respect to any Mortgage Loan, those customary mortgage master servicing
      practices of prudent mortgage servicing institutions that master service
      mortgage loans of the same type and quality as such Mortgage Loan in the
      jurisdiction where the related Mortgaged Property is located, to the extent
      applicable to the Indenture Trustee or the Master Servicer (except in its
      capacity as successor to the Servicer).

     

    Accrual
      Period:
      With
      respect to any Payment Date and the Notes, other than the Class II-A Notes
      and
      Class II-M-1 Notes, the period from the preceding Payment Date (or in the case
      of the first Payment Date, from the Closing Date) to and including the day
      preceding such Payment Date. With respect to any Payment Date and the Class
      II-A
      Notes and Class II-M-1 Notes, the prior calendar month. Accrued Note Interest
      for the Notes, other than the Class II-A Notes and Class II-M-1 Notes, shall
      be
      calculated on the basis of the actual number of days in the Accrual Period
      and a
      360-day year. Accrued Note Interest on the Class II-A Notes and Class II-M-1
      Notes shall be calculated on the basis of a 360-day year consisting of twelve
      30-day months.

     

    Accrued
      Note Interest:
      With
      respect to any Payment Date and each Class of Notes, interest accrued during
      the
      related Accrual Period at the then-applicable Note Interest Rate on the related
      Note Principal Balance thereof immediately prior to such Payment Date, plus
      any
      Accrued Note Interest remaining unpaid from any prior Payment Date with interest
      thereon at the related Note Interest Rate.

     

    Additional
      Form 10-D Disclosure:
      Has the
      meaning set forth in Section 4.06 of the Master Servicing
      Agreement.

     

    Additional
      Form 10-K Disclosure:
      Has the
      meaning set forth in Section 4.06 of the Master Servicing
      Agreement.

     

    Additional
      Negative Amortization Principal Amount:
      For any
      Payment Date, the excess, if any, of (x) the Negative Amortization Amount over
      (y) the Principal Remittance Amount for the Group I Loans (without regard to
      the
      last sentence of the definition thereof).

     

    Adjustment
      Fraction:
      For any
      Payment Date with respect to the Class
      I-A
      Notes and Class I-M Notes,
      a
      fraction, (x) the numerator of which is the aggregate Stated Principal Balance
      of the Group I Loans at the beginning of the related Due Period, and (y) the
      denominator of which is the aggregate Note Principal Balance of the Class I-A
      Notes and Class I-M Notes immediately prior to that Payment Date.

     

    Adjustment
      Date:
      As to
      each Mortgage Loan, each date set forth in the related Mortgage Note on which
      an
      adjustment to the interest rate on such Mortgage Loan becomes
      effective.

     

    Affiliate:
      With
      respect to any Person, any other Person controlling, controlled by or under
      common control with such Person. For purposes of this definition, “control”
means the power to direct the management and policies of a Person, directly
      or
      indirectly, whether through ownership of voting securities, by contract or
      otherwise and “controlling” and “controlled” shall have meanings correlative to
      the foregoing.

     

    Allocable
      Share:
      As to
      any Payment Date, the Subordinate Optimal Principal Amount and any Class of
      Group II Subordinate Notes, the portion of the Subordinate Optimal Principal
      Amount allocable to such Class, equal to the product of the Subordinate Optimal
      Principal Amount on such Payment Date and a fraction, the numerator of which
      is
      the related Note Principal Balance thereof and the denominator of which is
      the
      aggregate of the Note Principal Balances of the Group II Subordinate Notes;
      provided, that except as described in the succeeding sentence, no class of
      Group
      II Subordinate Notes (other than the class of Class II-M Notes
      outstanding with the lowest numerical designation, or the Class II-B Notes,
      if
      the aggregate Note Principal Balance of the Class II-M Notes has been reduced
      to
      zero) shall be entitled on any Payment Date to receive distributions pursuant
      to
      clauses (2), (3) and (5) of the definition of Subordinate Optimal Principal
      Amount unless the Class Prepayment Distribution Trigger for the related Class
      is
      satisfied for such Payment Date. If on any Payment Date the Note Principal
      Balance of any Class of Group II Subordinate Notes for which the related Class

    One-Month
      LIBOR:

      Administrator on the related Interest Determination Date on the basis of the
      London interbank offered rate for one-month United States dollar deposits,
      as
      such rates appear on the Telerate Screen Page 3750, as of 11:00 a.m. (London
      time) on such Interest Determination Date.

     

    In
      the
      event that on any Interest Determination Date, Telerate Screen Page 3750 fails
      to indicate the London interbank offered rate for one-month United States dollar
      deposits, then One-Month LIBOR for the related Accrual Period will be
      established by the Securities Administrator as follows:

     

    (i) If
      on
      such Interest Determination Date two or more Reference Banks provide such
      offered quotations, One-Month LIBOR for the related Accrual Period shall be
      the
      arithmetic mean of such offered quotations (rounded upwards if necessary to
      the
      nearest whole multiple of 1/16%).

     

    (ii) If
      on
      such Interest Determination Date fewer than two Reference Banks provide such
      offered quotations, One-Month LIBOR for the related Accrual Period shall be
      the
      higher of (i) One-Month LIBOR as determined on the previous Interest
      Determination Date and (ii) the Reserve Interest Rate.

     

    (iii) If
      no
      such quotations can be obtained and no Reference Bank rate is available,
      One-Month LIBOR will be the One-Month LIBOR rate applicable to the preceding
      Accrual Period.

     

    The
      establishment of One-Month LIBOR on each Interest Determination Date by the
      Securities Administrator and the Securities Administrator’s calculation of the
      applicable Note Interest Rate applicable for the related Accrual Period shall
      (in the absence of manifest error) be final and binding.

      preceding such Payment Date, and the denominator of which is the aggregate
      Stated Principal Balance of the Mortgage Loans in Loan Group II-C and Loan
      Group
      II-NC as of the beginning of the related Due Period, exceeds such percentage
      as

      the
      Class II-A-1, Class II-A-2, Class II-A-3 and Class II-A-4 Notes for such Payment
      Date will equal 100%.

    Six-Month
      LIBOR:
      With
      respect to any Accrual Period, the rate determined by the Securities
      Administrator on the related Interest Determination Date on the basis of the
      London interbank offered rate for six-month United States dollar deposits,
      as
      such rates appear on the Telerate Screen Page 3750, as of 11:00 a.m. (London
      time) on such Interest Determination Date.

     

    In
      the
      event that on any Interest Determination Date, Telerate Screen Page 3750 fails
      to indicate the London interbank offered rate for six-month United States dollar
      deposits, then Six-Month LIBOR for the related Accrual Period will be
      established by the Securities Administrator as follows:

     

    (i) If
      on
      such Interest Determination Date two or more Reference Banks provide such
      offered quotations, Six-Month LIBOR for the related Accrual Period shall be
      the
      arithmetic mean of such offered quotations (rounded upwards if necessary to
      the
      nearest whole multiple of 1/16%).

     

    (ii) If
      on
      such Interest Determination Date fewer than two Reference Banks provide such
      offered quotations, Six-Month LIBOR for the related Accrual Period shall be
      the
      higher of (i) Six-Month LIBOR as determined on the previous Interest
      Determination Date and (ii) the Reserve Interest Rate.

     

    (iii) If
      no
      such quotations can be obtained and no Reference Bank rate is available,
      Six-Month LIBOR will be the Six-Month LIBOR rate applicable to the preceding
      Accrual Period.

     

    The
      establishment of Six-Month LIBOR on each Interest Determination Date by the
      Securities Administrator and the Securities Administrator’s calculation of the
      applicable Note Interest Rate applicable for the related Accrual Period shall
      (in the absence of manifest error) be final and binding.

      Date, as specified in the amortization schedule at the time applicable thereto
      (after adjustment for previous principal prepayments but before any adjustment
      to such amortization schedule by reason of any bankruptcy or similar proceeding
      or any moratorium or similar waiver or grace period);

     

    (2)         
       the
      applicable Subordinate Prepayment Percentage of the Stated Principal Balance
      of
      each Mortgage Loan in the related Loan Group which was the subject of a
      prepayment in full received by the Servicer during the applicable Prepayment
      Period;

     

    (3)

      Loan in the related Loan Group;

      the
      related Due Period over (b) the sum of the amounts distributable to the Holders
      of the related Senior Notes pursuant to clause (4) of the definition of “Senior
      Optimal Principal Amount” on such Payment Date;

     

    (5)        
       the
      applicable Subordinate Prepayment Percentage of the sum of (a) the Stated
      Principal Balance of each Mortgage Loan in the related Loan Group which was

      such
      substitute mortgage loan; and

     

    (6) on
      the
      Payment Date on which the Note Principal Balances of the related Group II Senior
      Notes have all been reduced to zero, 100% of any applicable Senior Optimal
      Principal Amount. 

     

    Subordinate
      Percentage:
      As of
      any Payment Date and with respect to Loan Group II-C and Loan Group II-NC,
      100%
      minus the related Senior Percentage for the Class II-A-1, Class II-A-2, Class

    Subordinate
      Prepayment Percentage:
      As of
      any Payment Date and with respect to Loan Group II-C and Loan Group II-NC,
      100%
      minus the related Senior Prepayment Percentage for such Loan Group, except
      that
      on any Payment Date after the Note Principal Balance of each class of Group
      II
      Senior Notes of the related Note Group have each been reduced to zero, if (A)
      the weighted average of the Subordinate Percentages on such Payment Date equals
      or exceeds two times the initial weighted average of the Subordinate Percentages
      and (B) the aggregate Stated Principal Balance of the Mortgage Loans delinquent
      60 days or more (including for this purpose any such Mortgage Loans in
      foreclosure and bankruptcy and Mortgage Loans with respect to which the related
      mortgaged property has been acquired by the trust), averaged over the last
      six
      months, as a percentage of the sum of the aggregate Note Principal Balance
      of
      the Group II Subordinate Notes does not exceed 50%, the Subordinate Prepayment
      Percentage for the Group II Subordinate Notes with respect to such Loan Group
      will equal 100%. If the above test is not satisfied on any Payment Date after
      the Note Principal Balance of each class of Senior Notes of the related Note
      Group have each been reduced to zero, then the Subordinate Prepayment Percentage
      with respect to such Loan Group shall equal zero for such Payment
      Date.

     

    Subsequent
      Recoveries:
      Unexpected recoveries, net of reimbursable expenses, with respect to a
