evidencing a percentage interest in the distributions allocable to the Class A-[1][2][3][4][5] Certificates with respect to a Trust Fund consisting primarily of a pool of one-to four-family hybrid adjustable-rate first lien mortgage loans, which may be subject to negative amortization, formed and sold by AMERICAN HOME MORTGAGE ASSETS LLC.

This Certificate is payable solely from the assets of the Trust Fund, and does not represent an obligation of or interest in American Home Mortgage Assets LLC, the Master Servicer, the Securities Administrator or the Trustee referred to below or any of their affiliates. Neither this Certificate nor the underlying Mortgage Loans are guaranteed or insured by any governmental agency or instrumentality or by American Home Mortgage Assets LLC, the Master Servicer, the Securities Administrator, the Trustee or any of their affiliates. None of the Company, the Master Servicer, the Securities Administrator or any of their affiliates will have any obligation with respect to any certificate or other obligation secured by or payable from payments on the Certificates.

This certifies that Cede & Co. is the registered owner of the Percentage Interest evidenced by this Certificate (obtained by dividing the Initial Certificate Principal Balance of this Certificate by the aggregate Initial Certificate Principal Balance of all Class A-[1][2][3][4][5] Certificates, both as specified above) in certain distributions with respect to the Trust Fund consisting primarily of an interest in a pool of one- to four-family hybrid adjustable-rate first lien mortgage loans (the “Mortgage Loans”),which may be subject to negative amortization, sold by American Home Mortgage Assets LLC (hereinafter called the “Company,” which term includes any successor entity under the Agreement referred to below). The Trust Fund was created pursuant to a Pooling and Servicing Agreement, dated as specified above (the “Agreement”), among the Company, the Master Servicer, the Securities Administrator and Deutsche Bank National Trust Company, as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, the capitalized terms used herein have the meanings assigned in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following (the “Distribution Date”), commencing as described in the Agreement, to the Person in whose name this Certificate is registered, so long as this Certificate is a Book-Entry Certificate, at the close of business on the Business Day immediately prior to such Distribution Date, but if this Certificate is no longer a Book-Entry Certificate, then to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the calendar month preceding such Distribution Date (the “Record Date”), from the related Available Funds in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount of interest and principal, if any, required to be distributed to Holders of Class A-[1][2][3][4][5] Certificates on such Distribution Date.

Distributions on this Certificate will be made by the Securities Administrator either in immediately available funds (by wire transfer or otherwise) for the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator at least 5 Business Days prior to the related Record Date, or by check mailed to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register.

[For the Class A-3 Certificates and Class A-5 Certificates] [Financial Security Assurance Inc. (the “Certificate Insurer”), in consideration of the payment of the premium and subject to the terms of the financial guaranty insurance policy (the “Policy”) issued thereby, has unconditionally and irrecovably guaranteed the payment of an amount equal to the Scheduled Payment with respect to the Class A-[3][5] Certificates with respect to each Distribution Date.]

[For the Class A-3 Certificates and Class A-5 Certificates] [Prior to the termination of all of the supplemental interest trusts, each Transferee of this Certificate shall be deemed to have made the representations in Section 5.02 of the Agreement.]

[For the Class A-5 Certificates] [No transfer of this Certificate shall be made except in accordance with Section 5.02 of the Agreement.]

Notwithstanding the above, the final distribution on this Certificate will be made after due notice of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose in the City of Minneapolis and State of Minnesota. The Initial Certificate Principal Balance of this Certificate is set forth above. The Certificate Principal Balance hereof will be reduced to the extent of distributions allocable to principal.

This Certificate is one of a duly authorized issue of Certificates issued in several Classes designated as Mortgage-Backed Pass-Through Certificates of the Series specified hereon (herein collectively called the “Certificates”).

The Certificates are limited in right of payment to certain collections and recoveries respecting the Mortgage Loans, all as more specifically set forth herein and in the Agreement. In the event Master Servicer funds are advanced with respect to any Mortgage Loan, such advance is reimbursable to the Master Servicer, to the extent provided in the Agreement, from related recoveries on such Mortgage Loan or from other cash that would have been distributable to Certificateholders.

As provided in the Agreement, withdrawals from the Distribution Account created for the benefit of Certificateholders may be made by the Master Servicer from time to time for purposes other than distributions to Certificateholders, such purposes including without limitation reimbursement to the Trustee, the Company and the Master Servicer of advances made, or certain expenses incurred, by either of them.

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

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

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

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

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

This Certificate shall be governed by and construed in accordance with the laws of the State of New York.

The Mortgage Loans are subject to optional termination in whole, but not in part, by the Servicer or its designee on or after the first Distribution Date on which the aggregate outstanding Stated Principal Balance of the Mortgage Loans is less than or equal to 1% of the Aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-off Date.

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

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