Ladies and Gentlemen:

I am delivering this opinion as general counsel (“Counsel”) of National Rural Utilities Cooperative Finance Corporation, a District of Columbia cooperative association (the “Borrower”), and am familiar with matters pertaining to the loan to Borrower in the principal amount of $_______________, provided for in Master Note Purchase Agreement, dated as of __________________, 2015, as well as the Supplemental Note Purchase Agreement dated as of _____________, 20___ (together, as from time to time amended, the “Note Purchase Agreement”), among the Borrower, Farmer Mac Mortgage Securities Corporation (the “Purchaser”) and Federal Agricultural Mortgage Corporation (“Farmer Mac”).

I have examined such corporate records and proceedings of the Borrower, and such other documents as I have deemed necessary as a basis for the opinions hereinafter expressed.

I have also examined the following documents as executed and delivered: (a) the Note Purchase Agreement; (b) the Note dated as of ____________, in the principal amount of $____________ (“Note”), said Note payable to the Purchaser; and (c) the Amended, Restated and Consolidated Pledge Agreement, dated as of __________________, 2015, among the Borrower, the Purchaser, Farmer Mac and U.S. Bank National Association (as amended, the “Pledge Agreement”). The documents described in items (a) through (c) above are collectively referred to herein as the “Note Documents.”

Based on the foregoing, but subject to the assumptions, exceptions, qualifications and limitations hereinafter expressed, I am of the opinion that:

(1)The Borrower has been duly incorporated and is validly existing as a cooperative association in good standing under the laws of the District of Columbia with corporate power and authority to execute and perform its obligations under the Note Documents.

(2)The Note Documents have been duly authorized, executed and delivered by the Borrower, and such documents constitute the legal, valid and binding agreements of the Borrower, enforceable against the Borrower in accordance with their respective terms.

(3)Neither the execution nor the delivery by the Borrower of any of the Note Documents nor the consummation by the Borrower of any of the transactions contemplated therein, including, without limitation, the pledge of the Pledged Securities (as such term is defined in the Pledge Agreement) to Farmer Mac, nor the fulfillment by the Borrower of the terms of any of the Note Documents will conflict with or violate, result in a breach of or constitute a default under any term or provision of the Articles of Incorporation or By-laws of the Borrower or any law or any regulation or any order known to Counsel currently applicable to the Borrower of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Borrower or the terms of any indenture, deed of trust, note, note agreement or instrument to which the Borrower is a party or by which the Borrower or any of its properties is bound.

(4)No approval, authorization, consent, order, registration, filing, qualification, license or permit of or with any state or Federal court or governmental agency or body having jurisdiction over the Borrower is required for any consummation by the Borrower of the transactions contemplated by the Note Documents; provided, however, no opinion is expressed as to the applicability of any Federal or state securities law to any sale, transfer or other disposition of the Note after the date hereof.

(5)Except as set forth in writing and previously delivered to Farmer Mac or attached hereto as Exhibit A, there is no pending or, to Counsel’s knowledge, threatened action, suit or proceeding before any court or governmental agency, authority or body or any arbitrator with respect to the Borrower, or any of the Note Documents, which, if adversely determined, would have a material adverse effect on the Borrower’s financial condition or its ability to perform its obligations under any of the Note Documents.

(6)With respect to the Pledged Securities in the Certificate of Pledged Collateral (as such term is defined in the Pledge Agreement), (x) all action with respect to the recording, registering or filing of financing statements in the jurisdiction of organization of National Rural has been taken as is necessary to perfect the security interest intended to be created in such items under the Uniform Commercial Code and (y) in the case of each Eligible Security (as such term is defined in the Pledge Agreement) constituting a certificated security or instrument under the Uniform Commercial Code, such Eligible Security has been delivered to the Collateral Agent such that the taking and retention of the possession by the Collateral Agent of such Eligible Security is sufficient to perfect the security interest to be created under the Uniform Commercial Code. For purposes of the opinion set forth in this section (6), I have assumed that the Uniform Commercial Code of the District of Columbia is the same as that of the State of New York.

The foregoing opinions are subject to the following assumptions, exceptions, qualifications and limitations:

A.    I am a member of the Bar of the District of Columbia and render no opinion on the laws of any jurisdiction other than the laws of the District of Columbia, the federal laws of the United States of America and the General Corporation Law of the District of Columbia.

B.    My opinions are limited to the present laws and to the facts, as they presently exist. I assume no obligation to revise or supplement this opinion should the present laws of the jurisdictions referred to in paragraph A above be changed by legislative action, judicial decision or otherwise.

C.    The opinions expressed in paragraph 2 above shall be understood to mean only that if there is a default in performance of an obligation, (i) if a failure to pay or other damage can be shown and (ii) if the defaulting party can be brought into a court which will hear the case and apply the governing law, then, subject to the availability of defenses, and to the exceptions set forth in the next paragraph, the court will provide a money damage (or perhaps injunctive or specific performance) remedy.

D.     My opinions are also subject to the effect of: (1) bankruptcy, insolvency, reorganization, receivership, moratorium and other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances, fraudulent transfers and preferential transfers); and (2) the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the applicable agreements are considered in proceeding in equity or at law).

E.    This letter is rendered to you in connection with the Note Documents and the transactions related thereto, and may not be relied upon by any other person or by you in any other context or for any other purpose.

F.    I have assumed with your permission (i) the genuineness of all signatures by each party other than the Borrower, (ii) the authenticity of documents submitted to me as originals and the conformity to authentic original documents of all documents submitted to me as copies, and (iii) the due execution and delivery, pursuant to due authorization, of the Note Documents by each party other than the Borrower.

Yours sincerely,

Roberta B. Aronson
