ARTICLE IX

GUARANTEE

SECTION 9.01. Guarantee.

(a) The Guarantor agrees to pay in full to the holder of each Note, the principal of, and interest on, the Notes when due, whether at maturity, upon redemption or otherwise (the “Guaranteed Obligations”), on the applicable due date for such payment.

(b) The Guarantor’s obligations hereunder shall inure to the benefit of and shall be enforceable by any holder of a Note if, for reason beyond the control of such holder, such holder shall have failed to receive the interest or principal, as applicable, payable to such holder any payment date, redemption date or stated maturity date. The Guarantor hereby irrevocably agrees that its obligations hereunder shall be unconditional, irrespective of the validity, legality or enforceability of, or any change in or amendment to, this Agreement, the Pledge Agreement or any Note, the absence of any action to enforce the same, the waiver or consent by the holder of any Note or by the Collateral Agent with respect to any provisions of this Agreement or the Pledge Agreement, or any action to enforce the same or any other circumstance that might otherwise constitute a legal or equitable discharge or defense of a guarantor. The Guarantor hereby waives diligence, presentment, demand of payment, protest or notice with respect to each Note or the interest represented thereby, and all demands whatsoever, and covenants that the guarantee will not be discharged except upon complete irrevocable payment of the principal and interest obligations represented by the Notes.

(c) The Guarantor shall be subrogated to and is hereby assigned all rights of the holder of the Notes against National Rural and the proceeds of the Pledged Collateral, all in respect of any amounts paid by the Guarantor pursuant to the provisions of the guarantee contained in this Article IX. Each holder shall execute and deliver to the Guarantor in each holder’s name such instruments and documents as the Guarantor may reasonably request in writing confirming or evidencing such subrogation and assignment.

(d) No reference herein shall alter or impair the guarantee, which is absolute and unconditional, of the due and punctual payment of principal of, and interest on, the Notes, on the dates such payments are due.

(e) The guarantee is not an obligation of, and is not a guarantee as to principal or interest by the Farm Credit Administration, the United States or any other agency or instrumentality of the United States (other than the Guarantor).

(f) The guarantee shall be governed by, and construed in accordance with, Federal law. To the extent Federal law incorporates state law, that state law shall be the laws of the District of Columbia applicable to contracts made and performed therein.

SECTION 9.02. Control by the Guarantor.

If the Guarantor is the Control Party, the Guarantor shall be considered the holder of all Notes outstanding for all purposes under the Pledge Agreement and shall be permitted to take any and all actions permitted to be taken by the holder thereunder. The Control Party will have the sole right to direct the time, method and place of conducting any proceeding for any remedy available to the Collateral Agent or any holder with respect to the Notes or exercising any power conferred on the Collateral Agent with respect to the Notes provided that:

(i) such direction shall not be in conflict with any rule of law or with the Pledge Agreement;

(ii) the Collateral Agent shall have been provided with indemnity from the Control Party reasonably satisfactory to it; and

(iii) the Collateral Agent may take any other action deemed proper by such Collateral Agent that is not inconsistent with such direction, provided, however, that the Collateral Agent need not take any action which it determines might expose it to liability.

[FORM OF OPINION OF COUNSEL TO NATIONAL RURAL]

[•]

Federal Agricultural Mortgage Corporation

▇▇▇▇ ▇▇▇▇▇▇-▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇

▇▇▇▇▇ ▇▇▇

▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

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 $500,000,000.00, provided for in the Note Purchase Agreement, dated as of December 15, 2008 (“Note Purchase Agreement"), among the Borrower, ▇▇▇▇▇▇ Mac Mortgage Securities Corporation (the “Purchaser”) and Federal Agricultural Mortgage Corporation (“▇▇▇▇▇▇ 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 Pledge Agreement, dated as of December 15, 2008, among the Borrower, the Purchaser, ▇▇▇▇▇▇ Mac and U.S. Bank Trust National Association. 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 ▇▇▇▇▇▇ 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 ▇▇▇▇▇▇ Mac, 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, (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 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,

▇▇▇▇ ▇. List
