FIRST NATIONAL CORPORATION RESTRICTED STOCK UNIT AGREEMENT

Exhibit 10.1

FIRST NATIONAL CORPORATION

RESTRICTED STOCK UNIT AGREEMENT

This Restricted Stock Unit Agreement (the “Agreement”), dated as of                     , by and between First National Corporation (the “Company”) and                      evidences the grant on                      by the Company of an award of restricted stock units (the “Restricted Stock Unit Award”) to you and your acceptance of the Restricted Stock Unit Award.

The grant of this Restricted Stock Unit Award is made in accordance with the First National Corporation 2014 Stock Incentive Plan (the “Plan”), a copy of which is available from the Company upon request. The terms of the Plan are incorporated into this Agreement by reference. In the case of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control. Any term used in this Agreement that is defined in the Plan shall have the same meaning given to that term in the Plan. References in this Agreement to the “Company” also shall mean and refer to any business entity that, directly or indirectly through one or more intermediaries, controls, is controlled by, or is under common control with the Company, unless the context otherwise requires.

1. Award of Restricted Stock Units.

(a) The Board awards you              restricted stock units (the “Restricted Stock Units”). Each Restricted Stock Unit represents the right to receive one share of common stock of the Company (“Company Stock”), subject to the vesting schedule in Section 2 and the other terms and conditions of this Agreement and the Plan.

(b) The Restricted Stock Units shall be credited to a separate account maintained for you on the books and records of the Company (the “Account”). All amounts credited to the Account shall continue for all purposes to be part of the general assets of the Company.

2. Vesting. Except as otherwise provided herein, provided that you remain an employee of the Company through the applicable vesting date, the Restricted Stock Units will vest in accordance with the following schedule (the period during which the restrictions apply, the “Restricted Period”):

Vesting Date Number of Restricted Stock Units That Vest

Once vested, the Restricted Stock Units become “Vested Units” and shares of Company Stock representing the Vested Units will be issued in accordance with the settlement procedures set forth in Section 6.

3. Effect of Termination.

(a) If your employment is terminated for any reason other than your death or Disability before the vesting dates, all Restricted Stock Units that are not then vested shall be automatically forfeited upon such termination of employment and neither the Company nor any Affiliate shall have any further obligation to you under this Agreement.

(b) If you die or become Disabled while employed, all Restricted Stock Units that are not vested shall become Vested Units as of the date of your death or Disability.

(c) Unless otherwise determined by the Board in accordance with Section 15 of the Plan at the time of a Change in Control, a Change in Control shall have no impact on the vesting of the Restricted Stock Units.

4. Restrictions. Subject to any exceptions set forth in this Agreement or the Plan, during the Restricted Period and until such time as the Restricted Stock Units are settled in accordance with Section 6, the Restricted Stock Units or the rights relating thereto may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by you. Any attempt to assign, alienate, pledge, attach, sell or otherwise transfer or encumber the Restricted Stock Units or the rights

50

relating thereto shall be wholly ineffective and, if any such attempt is made, the Restricted Stock Units will be forfeited by you and all of your rights to such units shall immediately terminate without any payment or consideration by the Company. Notwithstanding any other provision in this Agreement to the contrary, no shares of Company Stock underlying the Restricted Stock Units may be sold until the expiration of six months from the Date of Grant.

5. Rights as a Shareholder.

(a) You shall not have any rights of a shareholder with respect to the shares of Company Stock underlying the Restricted Stock Units unless and until the Restricted Stock Units vest and are settled by the issuance of such shares of Company Stock.

(b) Upon and following the settlement of the Restricted Stock Units, you shall be the record owner of the shares of Company Stock underlying the Restricted Stock Units unless and until such shares are sold or otherwise disposed of, and as record owner shall be entitled to all rights of a shareholder of the Company (including voting rights).

6. Settlement of Vested Restricted Stock Units. Subject to Section 10, effective as of the vesting date the Company shall: (i) issue and deliver to you the number of shares of Company Stock equal to the number of Vested Units; and (ii) enter your name on the books of the Company as the shareholder of record with respect to the shares of Company Stock delivered to you.

7. No Right to Continued Employment. Neither the Plan nor this Agreement shall confer upon you any right to continued employment by the Company nor shall it interfere in any way with the right of the Company to terminate your employment at any time.

8. Change in Capital Structure. If the number of outstanding shares of the Company Stock is increased or decreased as a result of a subdivision or consolidation of shares, the payment of a stock dividend, stock split, or any other change in the capitalization effective without receipt of consideration by the Company, the number of Restricted Units awarded under this Agreement that have not vested shall be appropriately adjusted by the Company, whose determination shall be binding.

9. Governing Law. This Agreement is governed by the laws of the Commonwealth of Virginia.

10. Tax Liability and Withholding.

(a) You shall be required to pay to the Company, and the Company shall have the right to deduct from any compensation paid to you pursuant to the Plan, the amount of any required withholding taxes in respect of the Restricted Stock Units and to take all such other action as the Committee deems necessary to satisfy all obligations for the payment of such withholding taxes. The Committee may permit you to satisfy any federal, state or local tax withholding obligation by any of the following means, or by a combination of such means:

(i) tendering a cash payment;

(ii) authorizing the Company to withhold shares of Company Stock from the shares of Company Stock otherwise issuable or deliverable to you as a result of the vesting of the Restricted Stock Units; provided, however, that no shares of Common Stock shall be withheld with a value exceeding the minimum amount of tax required to be withheld by law; or

(iii) delivering to the Company previously owned and unencumbered shares of Company Stock.

(b) Notwithstanding any action the Company takes with respect to any or all income tax, payroll tax, or other tax-related withholding (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains your responsibility and the Company: (i) makes no representation or undertakings regarding the treatment of any Tax-Related Items in connection with the grant, vesting or settlement of the Restricted Stock Units or the subsequent sale of any shares; and (ii) does not commit to structure the Restricted Stock Units to reduce or eliminate your liability for Tax-Related Items.

11. Acceptance of Award. By signing below, you confirm your acceptance of the Restricted Stock Unit Award and agreement to the terms and conditions set forth in this Agreement, which, together with the terms of the Plan, shall become the Company’s Restricted Stock Unit Award Agreement with you. You also agree to all of the terms and conditions of the Plan. This Agreement will not be effective until it is signed and returned.

13. Compliance with Law. The issuance and transfer of shares of Company Stock shall be subject to compliance by the Company and you with all applicable requirements of federal and state securities laws and with all applicable requirements of any stock exchange on which the Company’s shares of common stock may be listed. No shares of Company Stock shall be issued or transferred unless and until any then applicable requirements of state and federal laws and regulatory agencies have been fully complied with to the satisfaction of the Company and its counsel.
