Ladies and Gentlemen:

     I have acted as counsel to American Express Receivables Financing Corporation II, American Express Receivables Financing Corporation III LLC and American Express Receivables Financing Corporation IV LLC (the “Registrants”) and have examined the Registration Statement on Form S-3 (File Nos. 333-155765, 333-155765-01, 333-155765-02 and 333-155765-03), filed by the Registrants with the Securities and Exchange Commission on November 28, 2008, and declared effective on February 3, 2009 (the “Registration Statement”), in connection with the registration under the Securities Act of 1933, as amended (the “Act”), of the Class A Series 2011-1 Floating Rate Asset Backed Certificates (the “Class A Certificates”) and the Class B Series 2011-1 Floating Rate Asset Backed Certificates (the “Class B Certificates” and, together with the Class A Certificates, the “Certificates”).

     I have examined such instruments, documents and records as I deemed relevant and necessary as a basis of my opinion hereinafter expressed. In such examination, I have assumed the following: (a) the authenticity of original documents and the genuineness of all signatures; (b) the conformity to the originals of all documents submitted to me as copies; and (c) the truth, accuracy and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates I have reviewed.

     Based on such examination and the other assumptions set forth herein, and subject to the qualification that I am admitted to the practice of law in the State of New York and do not purport to be expert in the laws of any jurisdiction other than the State of New York, I am of the opinion that when the Certificates have been duly executed and delivered in accordance with the Pooling and Servicing Agreement and sold, the Certificates will be legally issued, fully paid and non-assessable, and the holders of the Certificates will be entitled to the benefits of the Pooling and Servicing Agreement, except as enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance, moratorium, or other laws relating to or affecting the rights of creditors generally and general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief, regardless of whether such enforceability is considered in a proceeding in equity or at law.

     I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of my name wherever appearing in the Prospectus. In giving such consent, I do not consider that I am an “expert,” within the meaning of the term as used in the Act or the rules and regulations of the Securities and Exchange Commission issued thereunder, with respect to any part of the Registration Statement, including this opinion, as an exhibit or otherwise.
