MARTIN MARIETTA MATERIALS, INC.

RESTRICTED STOCK UNIT AGREEMENT

THIS RESTRICTED STOCK UNIT AGREEMENT (the “Award Agreement”), made as of                     , 20    , between Martin Marietta Materials, Inc., a North Carolina corporation (the “Corporation”), and «Name», «Address», «City_Zip» (the “Director”).

Pursuant to the Martin Marietta Materials, Inc. Amended and Restated Stock-Based Award Plan (the “Plan”), the Corporation hereby grants the Director                     Restricted Stock Units on the terms and conditions contained in this Award Agreement, and subject to the terms and conditions of the Plan. The term “Restricted Stock Unit” or “Unit(s)” as used in this Award Agreement refers only to the Restricted Stock Units awarded to the Director under this Award Agreement.

The Grant Date is                     , 20    .

The Restricted Stock Units granted hereby shall vest immediately, but Common Stock issuable with respect to Restricted Stock Units shall be delivered as provided in Section 5.

On each date that dividends are paid (each a “Dividend Payment Date”) on shares of the Corporation’s common stock, par value $0.01 per share (the “Common Stock”) with respect to which the record date (the “Record Date”) occurs before the conversion date, the Corporation will credit to an account for the Director an amount equal to the dividend paid on a share of the Common Stock multiplied by the number of Restricted Stock Units. These dividend equivalent amounts shall be paid (without interest) to the Director quarterly on each March 31, June 30, September 30 and December 31 during the period beginning on the date of this Award and ending on the conversion date; provided, however, that if any such date falls on a non-business day, such payment will be made on the business day immediately prior to such date. Any remaining dividend equivalent amounts credited to the account of the Director on the date that the Restricted Stock Units are converted to shares of Common Stock, or subsequently credited to such account with respect to a Record Date that occurs before the conversion date, shall be paid to the Director on the next successive Dividend Payment Date. The dividend equivalent amounts shall be paid from the general assets of the Corporation and shall be treated and reported as additional compensation for the year in which payment is made.

(ii) The other fifty percent (50%) (or, if the Director files an Election Form, the percentage not deliverable as provided in Section 5(a)(i)) of the Restricted Stock Units granted hereunder will be converted into shares of Common Stock and delivered to the Director as soon as practicable following the Grant Date.

(iii) The Director may file an Election Form to increase the percentage of Restricted Stock Units granted hereunder that are deliverable as provided in Section 5(a)(i) from fifty percent (50%) to any whole percentage greater than fifty percent (50%) and less than or equal to one hundred percent (100%).

(iv) For purposes of determining the number of shares of Common Stock deliverable to the Director under this Section 5, the conversion from Units to Common Stock will be one Unit for one share of Common Stock.

This Restricted Stock Unit grant shall not be assignable or transferable by the Director except by will or the laws of descent and distribution.

Except as otherwise required by law, the Corporation will not withhold any taxes at the time of vesting or distribution in accordance with Section 5. The Director is responsible for the payment of any applicable taxes.

In the event of a change in control of the Corporation, as defined in Section 11 of the Plan, all outstanding Units shall convert to shares of Common Stock. Such shares will be distributed no later than 2 ¹/₂ months following the date of such change in control.

As provided in Section 8 of the Plan, subject to certain limitations contained within Section 8, the Board of Directors may at any time amend, suspend or discontinue the Plan and the Management Development and Compensation Committee of the Board of Directors may at any time alter or amend all Award Agreements under the Plan. Notwithstanding Section 8 of the Plan, no such amendment, suspension or discontinuance of the Plan or alteration or amendment of this Award Agreement shall accelerate any distribution under the Plan or, except with the Director’s express written consent, adversely affect any Restricted Stock Unit granted under this Award Agreement; provided, however, that the Board of Directors or the Management Development and Compensation Committee may amend the Plan or this Award Agreement to the extent it deems appropriate to cause this Agreement or the Units hereunder to comply with Section 409A (including the distribution requirements thereunder) or be exempt from Section 409A or the tax penalty under Section 409A(a)(1)(B). If the Plan and the Award Agreement are terminated in a manner consistent with the requirements of Treas. Reg. § 1.409A-3(j)(4)(ix), the Board of Directors may, in its sole discretion, accelerate the conversion of Units to shares of Common Stock and immediately distribute such shares of Common Stock to the Director.

No Restricted Stock Unit granted under this Award Agreement is distributable nor is this Award Agreement enforceable until this Award Agreement has been fully executed by the Corporation and the Director. By executing this Award Agreement, the Director shall be deemed to have accepted and consented to any action taken under the Plan by the Management Development and Compensation Committee, the Board of Directors or their delegates.
