Section 2.05 Initial Capital Contribution of Owner Trust Estate. The Depositor hereby sells, assigns, transfers, conveys and sets over to the Trust, as of the date hereof, the sum of $1. The Owner Trustee hereby acknowledges receipt in trust from the Depositor, as of the date hereof, of the foregoing contribution, which shall constitute the initial corpus of the Trust and shall be deposited in the Certificate Distribution Account. The Owner Trustee also acknowledges on behalf of the Trust the receipt in trust of the Mortgage Loans, the rights with respect to the Swap Agreements, Cap Contracts and Floor Contract and the rights with respect to the representations and warranties made by the Sponsor under the Mortgage Loan Purchase Agreement which shall constitute the Owner Trust Estate.

Section 2.06 Declaration of Trust. The Owner Trustee hereby declares that it shall hold the Owner Trust Estate in trust upon and subject to the conditions set forth herein for the use and benefit of the Certificateholder, subject to the obligations of the Trust under the Basic Documents. It is the intention of the parties hereto that the Trust constitute a “statutory trust” under the Statutory Trust Statute and that this Trust Agreement constitute the governing instrument of such statutory trust.

Except with respect to the Mortgage Loans, which will be assigned to the Indenture Trustee pursuant to the Indenture, legal title to the Owner Trust Estate shall be vested at all times in the Trust as a separate legal entity except where applicable law in any jurisdiction requires title to any part of the Owner Trust Estate to be vested in a trustee or trustees, in which case title shall be deemed to be vested in the Owner Trustee, a co-trustee and/or a separate trustee, as the case may be.

Section 2.09 Situs of Trust. The Trust will be located and administered in the State of Delaware. All bank accounts maintained by the Owner Trustee on behalf of the Trust shall be located in the State of Delaware. The Trust shall not have any employees in any state other than Delaware; provided, however, that nothing herein shall restrict or prohibit the Owner Trustee from having employees within or without the State of Delaware or taking actions outside the State of Delaware in order to comply with Section 2.03. Payments will be received by the Trust only in Delaware, New York, Maryland, Minnesota or California, and payments will be made by the Trust only from Delaware, Maryland, Minnesota, California or New York. The only office of the Trust will be at the Corporate Trust Office in Delaware or California.

Section 2.10 Representations and Warranties of the Depositor. The Depositor hereby represents and warrants to the Owner Trustee that:

(i) The Depositor is duly organized and validly existing as a limited liability company in good standing under the laws of the State of Delaware, with power and authority to own its properties and to conduct its business as such properties are currently owned and such business is presently conducted.

(ii) The Depositor is duly qualified to do business as a foreign corporation in good standing and has obtained all necessary licenses and approvals in all jurisdictions in which the ownership or lease of its property or the conduct of its business shall require such qualifications and in which the failure to so qualify would have a material adverse effect on the business, properties, assets or condition (financial or other) of the Depositor.

(iii) The Depositor has the power and authority to execute and deliver this Trust Agreement and to carry out its terms; the Depositor has full power and authority to convey and assign the property to be conveyed and assigned to and deposited with the Trust as part of the Owner Trust Estate and the Depositor has duly authorized such conveyance and assignment and deposit to the Trust by all necessary corporate action; and the execution, delivery and performance of this Trust Agreement have been duly authorized by the Depositor by all necessary corporate action.

(iv) The consummation of the transactions contemplated by this Trust Agreement and the fulfillment of the terms hereof do not conflict with, result in any breach of any of the terms and provisions of, or constitute (with or without notice or lapse of time) a default under, the certificate of formation or the limited liability agreement or bylaws of the Depositor, or any indenture, agreement or other instrument to which the Depositor is a party or by which it is bound; nor result in the creation or imposition of any Lien upon any of its properties pursuant to the terms of any such indenture, agreement or other instrument (other than pursuant to the Basic Documents); nor violate any law or, to the best of the Depositor's knowledge, any order, rule or regulation applicable to the Depositor of any court or of any federal or state regulatory body, administrative agency or other governmental instrumentality having jurisdiction over the Depositor or its properties.

(v) The Trust is not required to register as an investment company under the Investment Company Act and is not under the control of a Person required to so register.

(vi) The Depositor has been a “qualified REIT subsidiary” as defined in Section 856(i) of the Code throughout its existence.

Section 2.11 Investment Company. Neither the Depositor nor any holder of a Certificate shall take any action which would cause the Trust to become an “investment company” which would be required to register under the Investment Company Act.

Section 2.12 Transfer of Trust Estate to Owner Trustee. (a) Effective as of the date hereof, the Depositor does hereby assign, transfer, and otherwise convey to, and deposit with, the Trust, until this Agreement terminates pursuant to Section 8.01, the entire Trust Estate, such conveyance to be made in exchange for the Notes and the Certificate. Such assignment includes, without limitation, all amounts payable to and all rights of the holder of the Collateral pursuant to this Agreement.

The conveyance of the Collateral and all other assets constituting the Trust Estate by the Depositor as contemplated hereby is absolute and is intended by the parties to constitute a sale of the Collateral and all other assets constituting the Trust Estate by the Depositor to the Trust. It is, further, not intended that such conveyance be deemed a pledge of security for a loan. If such conveyance is deemed to be a pledge of security for a loan, however, the Depositor intends that the rights and obligations of the parties to such loan shall be established pursuant to the terms of this Agreement. The Depositor also intends and agrees that, in such event:

(i) this Agreement shall constitute a security agreement under applicable law and shall be deemed to create a valid and continuing security interest (as defined in the applicable UCC) in the Trust Estate (including, without limitation, the Collateral, the Certificate Distribution Account and any proceeds thereof) in favor of the Trust, which security interest is prior to all other Liens, and is enforceable as such as against creditors of and purchasers from the Depositor;

(ii) other than the security interest granted to the Trust pursuant to this Agreement, Depositor has not pledged, assigned, sold, granted a security interest in, or otherwise conveyed any of the Trust Estate, has not authorized the filing of and is not aware of any financing statements against the Trust Estate that includes a description of collateral covering the Trust Estate other than any financing statements relating to the security interest granted to the Trust hereunder or that has been terminated. The Depositor is not aware of any judgment or tax lien filings against Depositor;

(iii) the Depositor owns and has good and marketable title to the Trust Estate free and clear of any Lien, claim or encumbrance of any Person;

(iv) the Certificate Distribution Account constitutes a “deposit account” within the meaning of the applicable UCC, and the Depositor has directed the Certificate Paying Agent to become the account holder of the Certificate Distribution Account. The Certificate Distribution Account is not in the name of any Person other than as provided in Section 3.10 of this Agreement. The Depositor has not consented to the maintenance of the Certificate Distribution Account in compliance with instructions of any Person other than the Certificate Paying Agent;

(v) the Trust Estate (excluding the Certificate Distribution Account and any proceeds thereof) constitutes “general intangibles” within the meaning of the applicable UCC. The Depositor has received all required consents and approvals to the pledge of the portions of the Trust Estate (excluding the Certificate Distribution Account and any proceeds thereof) constituting payment intangibles;

(vi) the Depositor has caused or will have caused, within ten days of the Closing Date, the filing of all appropriate financing statements in the appropriate filing offices under applicable law in order to perfect the security interest in the Trust Estate granted to the Trust hereunder. All financing statements filed or to be filed against the Depositor in favor of the Trust (or any subsequent assignee, including, without limitation, the Indenture Trustee) in connection herewith describing the Trust Estate contain a statement to the following effect, “A purchase of, or security interest in, any collateral described in this financing statement will violate the rights of the secured party;” and

(vii) the Depositor shall, to the extent consistent with this Agreement, take such additional reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other assets of the Trust Estate, such security interest would be a perfected security interest of first priority under applicable law and will be maintained as such throughout the life of this Agreement. Notifications to, and acknowledgments, receipts or confirmations from, Persons holding such property, shall be deemed to be notifications to, or acknowledgments, receipts or confirmations from, financial intermediaries, bailees or agents (as applicable) of the Owner Trustee on behalf of the Trust (or any subsequent assignee, including, without limitation, the Indenture Trustee) for the purpose of perfecting such security interest under applicable law.

(b) The Owner Trustee hereby acknowledges the receipt by it of the Trust Estate and such other documents and instruments referenced above, and declares that it holds and will hold the Trust Estate and such documents and instruments and that it holds and will hold all other assets and documents to be included in the Trust Estate, in trust for the exclusive use and benefit of the present and future Certificateholder.

(c) Except as expressly provided in Section 8.01, neither the Depositor nor any Certificateholder shall be able to revoke the Trust established hereunder. Except as provided in Sections 2.08, 4.01, 4.02, 4.03, 5.01 and 8.01 hereof, the Owner Trustee or Certificate Paying Agent (as applicable) shall not assign, sell, dispose of or transfer any interest in, nor may the Depositor or any Certificateholder withdraw from the Trust, the Collateral or other asset constituting the Trust Estate.

ARTICLE III

CONVEYANCE OF THE MORTGAGE LOANS; THE CERTIFICATE

Section 3.01 Conveyance of the Mortgage Loans. The Depositor, concurrently with the execution and delivery hereof, does hereby contribute, transfer, convey and assign to the Trust, on behalf of the Holders of the Notes and the Certificate, without recourse, all its right, title and interest in and to the Mortgage Loans, including all interest and principal received on or with respect to the Mortgage Loans after the Cut-off Date (other than payments of principal and interest due on the Mortgage Loans on or before the Cut-off Date). In addition, the Depositor hereby assigns to the Trust all of its right, title, and interest in, to, and under the Mortgage Loan Purchase Agreement. In addition, the Depositor hereby assigns to the Trust all of its right, title and interest in, to, and under the Swap Agreements, Cap Contracts and Floor Contract.

The conveyance of the Mortgage Loans by the Depositor to the Trust hereunder is intended to facilitate the simultaneous issuance of the Notes under the Indenture and issuance of the Certificate hereunder to the Depositor as Holder. The Depositor intends to sell the Certificate to an affiliate of the Depositor and the Sponsor. Accordingly, at the time of the transaction set forth herein, the Depositor will retain without interruption, through the ownership of the Certificate, the economic benefits associated with ownership of the Mortgage Loans as well as the economic burdens associated with such ownership, subject to the lien of the Indenture and subject to this Agreement. If the transactions contemplated by this Trust Agreement are determined to constitute a financing, the Depositor hereby grants to the Trust a security interest in the Owner Trust Estate and all distributions thereon and proceeds thereof, and this Trust Agreement shall constitute a security agreement under applicable law. In the event of a REMIC Conversion, the assets of the Owner Trust Estate will be comprised of REMIC Regular interests.

Section 3.02 Initial Ownership. Upon the formation of the Trust by the contribution by the Depositor pursuant to Section 2.05 and until the conveyance of the Mortgage Loans pursuant to Section 3.01 and the issuance of the Certificate, and thereafter except as otherwise permitted hereunder, the Depositor shall be the sole Certificateholder.

Section 3.03 The Certificate. The Certificate shall be issued in the form of a single Certificate, representing 100% Certificate Percentage Interest. The Certificate (which includes the Transferor Interest) shall initially be registered in the name of American Home Mortgage Investment Corp. The Certificate shall be executed on behalf of the Trust by manual or facsimile signature of an authorized officer of the Owner Trustee and authenticated in the manner provided in Section 3.04. The Certificate, bearing the manual or facsimile signatures of individuals who were, at the time when such signatures shall have been affixed, authorized to sign on behalf of the Trust, shall be validly issued and entitled to the benefit of this Trust Agreement, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the authentication and delivery of such Certificate or did not hold such offices at the date of authentication and delivery of such Certificate. A Person shall become a Certificateholder and shall be entitled to the rights and subject to the obligations of a Certificateholder hereunder upon such Person's acceptance of a Certificate duly registered in such Person's name, pursuant to Section 3.05.

A transferee of a Certificate shall become a Certificateholder and shall be entitled to the rights and subject to the obligations of a Certificateholder hereunder upon such transferee's acceptance of a Certificate duly registered in such transferee's name pursuant to and upon satisfaction of the conditions set forth in Section 3.05.

Section 3.04 Authentication of Certificate. The Owner Trustee shall cause the Certificate issued hereunder to be executed and authenticated on behalf of the Trust, authenticated and delivered to or upon the written order of the Depositor, signed by its chairman of the board, its president or any vice president, without further corporate action by the Depositor, in authorized denominations. The Certificate shall not entitle its holder to any benefit under this Trust Agreement or be valid for any purpose unless there shall appear on such Certificate a certificate of authentication substantially in the form set forth in Exhibit A, executed by the Owner Trustee or the Certificate Registrar by manual signature; such authentication shall constitute conclusive evidence that such Certificate shall have been duly authenticated and delivered hereunder. The Certificate shall be dated the date of its authentication.

Section 3.05 Registration of and Limitations on Transfer and Exchange of the Certificate. The Certificate Registrar shall keep or cause to be kept, a Certificate Register in which, subject to such reasonable regulations as it may prescribe, the Certificate Registrar shall provide for the registration of Certificate and of transfer and exchange of the Certificate as herein provided. The Securities Administrator shall be the initial Certificate Registrar. If the Certificate Registrar resigns or is removed, the Owner Trustee shall appoint a successor Certificate Registrar. The provisions of Sections 6.01, 6.04, 6.05, 6.06, 6.07, 6.08 and 7.01 shall apply to the Certificate Registrar to the same extent applicable to the Owner Trustee except the context requires otherwise.

Subject to satisfaction of the conditions set forth below with respect to the Certificate, upon surrender for registration of transfer of the Certificate at the office or agency maintained pursuant to Section 3.09, the Owner Trustee or the Certificate Registrar shall execute, authenticate and deliver in the name of the designated transferee or transferees, a new Certificate evidencing no less than a 100% Certificate Percentage Interest in authorized denominations of a like aggregate amount and dated the date of authentication by the Owner Trustee or the Certificate Registrar.

Every Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder or such Holder's attorney duly authorized in writing. Each Certificate surrendered for registration of transfer or exchange shall be cancelled and subsequently disposed of by the Certificate Registrar in accordance with its customary practice.

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

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

No transfer, sale, pledge or other disposition of a Certificate 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 Certificate 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 C which investment letter shall not be an expense of the Trust, the Owner Trustee, the Indenture Trustee, the Certificate Registrar, Securities Administrator, 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 Certificate Registrar 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 Certificate Registrar, the Securities Administrator, the Master Servicer, the Servicer, the Sponsor or the Depositor and (b) the transferee executes a representation letter, substantially in the form of Exhibit F to the Agreement, and the transferor executes a representation letter, substantially in the form of Exhibit E hereto, each acceptable to and in form and substance satisfactory to the Certificate Registrar, certifying the facts surrounding such transfer, which representation letters shall not be an expense of the Trust, the Owner Trustee, the Certificate Registrar, the Securities Administrator, the Master Servicer, the Servicer, the Sponsor or the Depositor and (B) the Certificate of Non-Foreign Status (in substantially the form attached hereto as Exhibit D) acceptable to and in form and substance reasonably satisfactory to the Certificate Registrar, which certificate shall not be an expense of the Trust, the Owner Trustee, the Certificate Registrar or the Depositor; provided, however that no certification or Opinion of Counsel will be required in connection with the initial transfer of any such Certificate by the Depositor to an affiliate of the Depositor. The Holder of a Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trust, the Owner Trustee, the Certificate Registrar, the Securities Administrator, 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.

Prior to a REMIC conversion no transfer, sale, pledge or other disposition of the Certificate or interest herein shall be made unless the intended transferee certifies in the form of Exhibit H hereto to the Owner Trustee, the Certificate Registrar, and the Indenture Trustee that, in connection with the transfer, it will acquire both the Trust Certificate and a 100% Percentage Interest in each Class of Privately Offered Notes then Outstanding, thus becoming a Single Owner upon completion of the transfer. Notwithstanding the foregoing, a Certificate may be pledged to secure indebtedness and may be the subject of repurchase agreements treated as secured indebtedness for federal income tax purposes. Upon a default under any such indebtedness, the lender or repurchase agreement counterparty, as applicable may deliver to the Certificate Registrar, the Securities Administrator, the Owner Trustee and the Indenture Trustee a certificate substantially in the form attached hereto as Exhibit I certifying that a default has occurred and that a REMIC Conversion should be undertaken. Notwithstanding the foregoing, the provisions of this paragraph shall not apply to the initial transfer of the Certificate to the Depositor or any Affiliate thereof or to the transfer to the Initial Single Owner.

No transfer of the Certificate or any interest therein shall be made to any Person unless the Depositor, the Owner Trustee, the Indenture Trustee, the Certificate Registrar and the Master Servicer are provided with an Opinion of Counsel which establishes to the satisfaction of the Certificate Registrar that the purchase of the Certificate, 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 Certificate Registrar the Securities Administrator, 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 this Agreement, which Opinion of Counsel shall not be an expense of the Depositor, the Owner Trustee, the Indenture Trustee, the Certificate Registrar, the Securities Administrator, the Master Servicer, the Servicer or the Sponsor. In lieu of such Opinion of Counsel, a Person acquiring such Certificate may provide a certification in the form of Exhibit G to this Agreement to the Depositor, the Owner Trustee and the Certificate Registrar, which the Depositor, the Owner Trustee, the Indenture Trustee, the Certificate 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 Certificate 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 Certificate Registrar shall be entitled to conclusively rely upon a representation (which, upon the request of the Owner Trustee or the Certificate Registrar, shall be a written representation) from the Depositor of the status of such transferee as an affiliate of the Depositor.

No transfer of any Trust Certificate shall be made unless the proposed transferee of such Trust Certificate (1) provides to the Securities Administrator the appropriate tax certification form that would eliminate any withholding or deduction for taxes from amounts payable by the Swap Provider pursuant to the related Swap Agreement, to the Securities Administrator on behalf of the Trust (i.e., IRS Form W-9 (or any successor form thereto), together with any applicable attachments) and (2) agrees to update such forms (i) upon expiration of any such form, (ii) as required under then applicable U.S. Treasury regulations and (iii) promptly upon learning that such form has become obsolete or incorrect, each as a condition to such transfer. Upon receipt of any such tax certification form from a proposed transferee of the Trust Certificate, the Securities Administrator will forward such tax certification form provided to it to the Swap Provider. The holder of the Trust Certificate and any transferee thereof will be deemed to have consented to the Securities Administrator forwarding to the Swap Provider any such tax certification form it has provided and updated in accordance with these transfer restrictions. Any purported sales or transfers of the Trust Certificate to a transferee which does not comply with the requirements of this paragraph will be deemed null and void under the Trust Agreement. So long as the holder of the Trust Certificate complies with these restrictions and the Swap Provider receives the appropriate tax certification forms as described above, under current federal income tax law, there will be no withholding or deduction for taxes from any amounts payable by the Swap Provider, pursuant to the related Swap Agreement, to the Securities Administrator on behalf of the Trust. In addition, upon a REMIC Conversion, the REMIC Indenture will provide for delivery to the Swap Provider of the appropriate tax certification from the owner of the Derivative Account, for federal income tax purposes, forms that would eliminate any withholding or deduction for taxes from amounts payable by the Swap Provider pursuant to the related Swap Agreement, to the Securities Administrator on behalf of the Trust, (i.e., IRS Form W-9 or IRS Form X-0XXX, X-0XXX, X-0XXX or W-8ECI, as applicable (or any successor form thereto), together with any applicable attachments) and any updates thereto from the then applicable persons required to provide such forms to the Swap Provider.

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

With respect the restriction on transfer of the Notes contained in this Section 3.05, any transferor providing an Opinion of Counsel shall (i) deliver such opinion to the appropriate addresses, (ii) confirm the acceptability of such opinion with the applicable addresses and (iii) inform the Note Registrar of delivery and confirmation described in clause (i) and clause (ii).

Section 3.06 Mutilated, Destroyed, Lost or Stolen Certificate. If (a) any mutilated Certificate shall be surrendered to the Certificate Registrar, or if the Certificate Registrar shall receive evidence to its satisfaction of the destruction, loss or theft of any Certificate and (b) there shall be delivered to the Certificate Registrar and the Owner Trustee such security or indemnity as may be required by them to save each of them harmless, then in the absence of notice to the Certificate Registrar or the Owner Trustee that such Certificate has been acquired by a bona fide purchaser, the Owner Trustee shall execute on behalf of the Trust, and the Owner Trustee or the Certificate Registrar shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like tenor and denomination. In connection with the issuance of any new Certificate under this Section 3.06, the Owner Trustee or the Certificate Registrar may require the payment of a sum sufficient to cover any expenses of the Owner Trustee or the Certificate Registrar (including fees and expenses of counsel) and any tax or other governmental charge that may be imposed in connection therewith. Any duplicate Certificate issued pursuant to this Section 3.06 shall constitute conclusive evidence of ownership in the Trust, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

Section 3.07 Persons Deemed a Certificateholder. Prior to due presentation of a Certificate for registration of transfer, the Owner Trustee, the Certificate Registrar or any Certificate Paying Agent may treat the Person in whose name the Certificate is registered in the Certificate Register as the owner of such Certificate for the purpose of receiving distributions pursuant to Section 5.01 and for all other purposes whatsoever, and none of the Trust, the Owner Trustee, the Certificate Registrar or any Certificate Paying Agent shall be bound by any notice to the contrary.

Section 3.08 Access to the Certificateholder’s Names and Addresses. The Certificate Registrar shall furnish or cause to be furnished to the Depositor, the Certificate Paying Agent or the Owner Trustee, within 15 days after receipt by the Certificate Registrar of a written request therefor from the Depositor, the Certificate Paying Agent or the Owner Trustee,  of the name and address of the Certificateholder as of the most recent record date.   The  Holder, by receiving and holding  the  Certificate, shall be deemed to have agreed not to hold any of the Trust, the Depositor, the Certificate Paying Agent, the Certificate Registrar or the Owner Trustee accountable by reason of the disclosure of its name and address, regardless of the source from which such information was derived.

Section 3.09 Maintenance of Office or Agency. The Owner Trustee on behalf of the Trust, shall maintain an office or offices or agency or agencies where the Certificate may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Owner Trustee in respect of the Certificate and the Basic Documents may be delivered. The Owner Trustee initially designates the office of the Securities Administrator for purposes of service of notices and demands and surrender. The Owner Trustee shall give prompt written notice to the Depositor, the Certificate Paying Agent, the Certificate Registrar and the Certificateholder of any change in the location of the Certificate Register or any such office or agency.

Section 3.10 Certificate Paying Agent. (a) The Certificate Paying Agent shall make distributions to the Certificateholder from the Certificate Distribution Account on behalf of the Trust in accordance with the provisions of the Certificate and the statement for such Payment Date provided by the Securities Administrator, in accordance with Section 7.05 of the Indenture hereof from payments remitted to the Certificate Paying Agent by the Indenture Trustee pursuant to Section 3.05 of the Indenture. The Trust hereby appoints the Securities Administrator as Certificate Paying Agent and the Securities Administrator hereby accepts such appointment and further agrees that it will be bound by the provisions of this Trust Agreement relating to the Certificate Paying Agent and shall:

(i) hold all sums held by it for the payment of amounts due with respect to the Certificate 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;

(ii) give the Owner Trustee notice of any default by the Trust of which a Responsible Officer of the Certificate Paying Agent has actual knowledge in the making of any payment required to be made with respect to the Certificate;

(iii) at any time during the continuance of any such default, upon the written request of the Owner Trustee forthwith pay to the Owner Trustee on behalf of the Trust all sums so held in Trust by such Certificate Paying Agent;

(iv) not resign from its position as Certificate Paying Agent so long as it is Securities Administrator except that it shall immediately resign as Certificate Paying Agent and forthwith pay to the Owner Trustee on behalf of the Trust all sums held by it in trust for the payment of the Certificate if at any time it ceases to meet the standards under this Section 3.10 required to be met by the Certificate Paying Agent at the time of its appointment;

(v) comply with all requirements of the Code with respect to the withholding from any payments made by it on the Certificate of any applicable withholding taxes imposed thereon and with respect to any applicable reporting requirements in connection therewith; and

(vi) not institute bankruptcy proceedings against the Issuing Entity in connection with this Trust Agreement.

(b) The Trust may revoke such power and remove the Certificate Paying Agent if it determines in its sole discretion that the Certificate Paying Agent shall have failed to perform its obligations under this Trust Agreement in any material respect. In the event that the Securities Administrator shall no longer be the Certificate Paying Agent under this Trust Agreement and Paying Agent under the Indenture, the Owner Trustee shall appoint a successor to act as Certificate Paying Agent (which shall be a bank or trust company) and which shall also be the successor Paying Agent under the Indenture. The Owner Trustee shall cause such successor Certificate Paying Agent or any additional Certificate Paying Agent appointed by the Owner Trustee to execute and deliver to the Owner Trustee an instrument to the effect set forth in Section 3.10(a) as it relates to the Certificate Paying Agent. The Certificate Paying Agent shall return all unclaimed funds to the Trust and upon removal of a Certificate Paying Agent such Certificate Paying Agent shall also return all funds in its possession to the Trust. The provisions of Sections 6.01, 6.04, 6.05, 6.06, 6.07, 6.08 and 7.01 shall apply to the Certificate Paying Agent to the same extent applicable to the Owner Trustee except the context requires otherwise. Any reference in this Agreement to the Certificate Paying Agent shall include any co-paying agent unless the context requires otherwise.

The Certificate Paying Agent shall establish and maintain with itself a trust account (the “Certificate Distribution Account”) in which the Certificate Paying Agent shall deposit, on the same day as it is received from the Indenture Trustee, each remittance received by the Certificate Paying Agent with respect to payments made pursuant to the Indenture. Funds in the Certificate Distribution Account shall not be invested. The Certificate Paying Agent shall make all distributions to the Certificate, from moneys on deposit in the Certificate Distribution Account, in accordance with Section 5.01 hereof.

In addition to the foregoing, the Owner Trustee is authorized, but shall not be obligated, except as otherwise provided in this Trust Agreement, to take all actions required of the Trust pursuant to the Basic Documents.

Section 4.02 General Duties. It shall be the duty of the Owner Trustee to discharge (or cause to be discharged) all of its responsibilities pursuant to the terms of this Trust Agreement and the Basic Documents to which the Trust is a party and to administer the Trust in the interest of the Certificateholder, subject to the Basic Documents and in accordance with the provisions of this Trust Agreement.

Such direction may be exercised at any time by written instruction of the Certificateholder pursuant to Article IV.

(b) Notwithstanding the foregoing, the Owner Trustee shall not be required to take any action hereunder or under any Basic Document if the Owner Trustee shall have reasonably determined, or shall have been advised by counsel, that such action is likely to result in liability on the part of the Owner Trustee or is contrary to the terms hereof or of any Basic Document or is otherwise contrary to law.

(c) Whenever the Owner Trustee is required to decide between alternative courses of action permitted or required by the terms of this Trust Agreement or under any Basic Document, or in the event that the Owner Trustee is unsure as to the application of any provision of this Trust Agreement or any Basic Document or any such provision is ambiguous as to its application, or is, or appears to be, in conflict with any other applicable provision, or in the event that this Trust Agreement permits any determination by the Owner Trustee or is silent or is incomplete as to the course of action that the Owner Trustee is required to take with respect to a particular set of facts, the Owner Trustee shall promptly give notice (in such form as shall be appropriate under the circumstances) to the Certificateholder requesting instruction as to the course of action to be adopted, and to the extent the Owner Trustee acts in good faith in accordance with any written instruction of the Certificateholder. If the Owner Trustee shall not have received appropriate instruction within 10 days of such notice (or within such shorter period of time as reasonably may be specified in such notice or may be necessary under the circumstances) it may, but shall be under no duty to, take or refrain from taking such action not inconsistent with this Trust Agreement or the Basic Documents, as it shall deem to be in the best interests of the Certificateholder, and the Owner Trustee shall have no liability to any Person for such action or inaction.

Notwithstanding the preceding sentence, the Owner Trustee will not prohibit any actions contemplated here in the case of a REMIC Conversion and will reasonably cooperate with the Securities Administrator in carrying out the events contemplated following a REMIC Conversion.

The Owner Trustee shall sign all tax and information returns prepared or caused to be prepared by the Securities Administrator pursuant to this Section 5.03 at the request of the Securities Administrator, and in doing so shall rely entirely upon, and shall have no liability for information or calculations provided by, the Securities Administrator. There shall be no separate tax reporting requirements with respect to the Transferor Interest.

The Paying Agent shall prepare or cause to be prepared the appropriate forms relating to the collection of withholding tax by the Certificate Registrar.

Subsequent to a TMP Trigger Event, the Securities Administrator shall prepare and file, or cause to be prepared and filed, in a timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return (Form 1066 or any successor form adopted by the Internal Revenue Service) and prepare and file or cause to be prepared and filed with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year with respect to any such REMIC, containing such information and at the times and in the manner as may be required by the Code or state or local tax laws, regulations, or rules, and furnish or cause to be furnished to the Certificateholder the schedules, statements or information at such times and in such manner as may be required thereby.

Section 5.04 Statements to the Certificateholder. On each Payment Date, the Securities Administrator shall make available to the Certificateholder the statement or statements provided to the Owner Trustee and the Certificate Paying Agent by the Securities Administrator pursuant to Section 7.05 of the Indenture with respect to such Payment Date.

Any separate trustee or co-trustee may at any time appoint the Owner Trustee as 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 Trust Agreement on its behalf and in its name. If any separate trustee or co-trustee shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts shall vest in and be exercised by the Owner Trustee, to the extent permitted by law, without the appointment of a new or successor co-trustee or separate trustee.

The Trust was created pursuant to a Short Form Trust Agreement, dated as of April [__], 2007, between the Depositor and Wilmington Trust Company, as owner trustee (the “Owner Trustee”, which term includes any successor entity under the Trust Agreement) (the “Short Form Trust Agreement”) as amended and restated by the Amended and Restated Trust Agreement dated as of April 20, 2007 (as amended and supplemented from time to time, together with the Short Form Trust Agreement, the “Trust Agreement”) among the Depositor, the Owner Trustee, Deutsche Bank National Trust Company, as indenture trustee and Xxxxx Fargo Bank, N.A. as Securities Administrator, a summary of certain of the pertinent provisions of which is set forth hereinafter. This Certificate is issued under and is subject to the terms, provisions and conditions of the Trust Agreement, to which Trust Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

This Certificate is one of a duly authorized issue of the Trust Certificate, Series 2007-2 (herein called the “Certificate”) issued under the Trust Agreement to which reference is hereby made for a statement of the respective rights thereunder of the Depositor, the Owner Trustee and the Holder of the Certificate and the terms upon which the Certificate is executed and delivered. All terms used in this Certificate which are defined in the Trust Agreement shall have the meanings assigned to them in the Trust Agreement. The Owner Trust Estate consists of the Mortgage Loans in the American Home Mortgage Investment Trust 2007-2. The rights of the Holder of the Certificate are subordinated to the rights of the Holders of the Notes, as set forth in the Indenture.

There will be distributed on the 25th day of each month or, if such 25th day is not a Business Day, the next Business Day (each, a “Payment Date”), commencing on May 25, 2007, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding such Payment Date (the “Record Date”), such Certificateholder's Percentage Interest in the amount to be distributed to the Certificateholder on such Payment Date.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Certificate Distribution Account that have been released from the Lien of the Indenture for payment hereunder and that neither the Owner Trustee in its individual capacity nor the Depositor is personally liable to the Certificateholder for any amount payable under this Certificate or the Trust Agreement or, except as expressly provided in the Trust Agreement, subject to any liability under the Trust Agreement.

No transfer, sale, pledge or other disposition of a Certificate 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 Certificate 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 Trust Agreement as Exhibit C (or in such form and substance reasonably satisfactory to the Certificate 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 Certificate 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 Certificate 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 Certificate Registrar, the Master Servicer, the Servicer, the Sponsor or the Depositor and (b) the transferee executes a representation letter, substantially in the form of Exhibit E to the Trust Agreement, and the transferor executes a representation letter, substantially in the form of Exhibit F to the Trust Agreement, each acceptable to and in form and substance satisfactory to the Certificate Registrar and the Depositor 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 Certificate Registrar, the the Master Servicer, the Servicer, the Sponsor or the Depositor and (B) the Certificate of Non-Foreign Status (in substantially the form attached to the Trust Agreement as Exhibit D) acceptable to and in form and substance reasonably satisfactory to the Certificate Registrar and the Depositor, which certificate shall not be an expense of the Trust, the Owner Trustee, the Indenture Trustee, the Securities Administrator, the Certificate Registrar, the Master Servicer, the Servicer, the Sponsor or the Depositor. The Holder of a Certificate desiring to effect such transfer shall, and does hereby agree to, indemnify the Trust, the Owner Trustee, the Indenture Trustee, the Certificate Paying Agent, the Certificate 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.

Prior to a REMIC conversion no transfer, sale, pledge or other disposition of the Certificate or interest herein shall be made unless the intended transferee certifies in the form of Exhibit H hereto to the Owner Trustee, the Certificate Registrar, and the Indenture Trustee that, in connection with the transfer, it will acquire both the Trust Certificate and a 100% Percentage Interest in each Class of Privately Offered Notes then Outstanding, thus becoming a Single Owner upon completion of the transfer and the Certificate Registrar has received proof of the Transferee’s status as a REIT or as a qualified REIT subsidiary, within the meaning of Section 856(a) or Section 856(i) of the Code, respectively. Notwithstanding the foregoing, a Certificate may be pledged to secure indebtedness and may be the subject of repurchase agreements treated as secured indebtedness for federal income tax purposes. Upon a default under any such indebtedness, the lender or repurchase agreement counterparty, as applicable may deliver to the Certificate Registrar, the Securities Administrator, the Owner Trustee and the Indenture Trustee a certificate substantially in the form attached hereto as Exhibit I certifying that a default has occurred and that a REMIC Conversion should be undertaken. Notwithstanding the foregoing, the provisions of this paragraph shall not apply to the initial transfer of the Certificate to the Depositor or any Affiliate thereof or to the transfer to the Initial Single Owner.

No transfer of the Certificate or any interest therein shall be made to any Person unless the Depositor, the Owner Trustee, the Indenture Trustee, the Certificate Registrar, the Master Servicer, the Servicer and the Sponsor are provided with an Opinion of Counsel which establishes to the satisfaction of the Certificate Registrar that the purchase of the Certificate 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 Certificate 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 Trust Agreement, which Opinion of Counsel shall not be an expense of the Depositor, the Owner Trustee, the Indenture Trustee, the Securities Administrator, the Certificate 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 Certificate Registrar, the Depositor and the Owner Trustee to the Agreement, which the Depositor, the Owner Trustee, the Indenture Trustee, the Securities Administrator, the Certificate 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 Certificate by the Depositor to an affiliate of the Depositor (in which case, the Depositor or any affiliate thereof shall have deemed to have represented that such affiliate is not a Plan or a Person investing Plan Assets of any Plan) and the Owner Trustee and the Certificate Registrar shall be entitled to conclusively rely upon a representation (which, upon the request of the Owner Trustee or the Certificate Registrar, shall be a written representation) from the Depositor of the status of such transferee as an affiliate of the Depositor.

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

Unless the certificate of authentication hereon shall have been executed by an authorized officer of the Owner Trustee, or an authenticating agent by manual signature, this Certificate shall not entitle the Holder hereof to any benefit under the Trust Agreement or be valid for any purpose.

THIS CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.
