EXHIBIT 10(iii)(n) AMENDED AND RESTATED MARTIN MARIETTA CORPORATION LONG TERM PERFORMANCE INCENTIVE COMPENSATION PLAN February 25, 1993 August 27, 1994 (Amended) 1. PURPOSE ------- The purpose of the Amended and Restated Long Term Performance Incentive Compensation Plan ("Plan") is to retain the services of key employees in positions which contribute materially to the successful operation of the business of the Corporation by rewarding such employees for their efforts in increasing the earnings of the Corporation, thereby enhancing the long-term value of the Corporation to the shareholders. It is intended that this purpose will be effected through the granting of performance units, as provided herein. The Plan was originally adopted by the Compensation Committee of the Board of Directors on November 12, 1990. The Plan was amended and restated by the Board of Directors, effective July 23, 1992. All Awards granted prior to July 23, 1992 will be governed by the terms of the Plan as adopted on November 12, 1990. All Awards granted on or after that date shall be governed by this Amended and Restated Plan. 2. DEFINITIONS ----------- As used in the Plan the following terms when capitalized, shall have the meanings set forth below: "Award" shall mean the granting by the Committee of Units in accordance with this Plan. "Base Earnings Share" shall mean, with respect to a particular Redemption Period for an Award, the value established by the Committee for use in computing the Redemption Value.

"Employee" means officers and other key employees of the Corporation but excludes directors who are not also officers or employees of the Corporation.

ELIGIBLE EMPLOYEES ------------------ 2 LONG TERM PERFORMANCE INCENTIVE COMPENSATION PLAN - ------------------------------------------------- Awards of Units may be granted only to exempt salaried employees of the Corporation. 5. TERMS OF AWARDS OF UNITS ------------------------ Awards of Units under this Plan will be made from time to time by the Committee. Units awarded to Employees on or after July 23, 1992 may be exchanged by such Employee for the Redemption Value of the Units in accordance with the terms of this Amended and Restated Plan. (a) For each Award of Units, the Committee shall determine the following terms: (i) whether the Units in the Award are non forfeitable immediately or the terms or conditions under which all or a portion of any Award shall become non forfeitable; (ii) the Redemption Period or Periods applicable to such Award; (iii) the Base Earnings Per Share(s) and Multiplier(s) applicable to the Redemption Period(s) for each such Award; and (iv) such other terms as the Committee deems appropriate. An Award of Units may have one or multiple Redemption Periods, Base Earnings Per Share, or Multipliers applicable to it. (b) An Award of Units shall be evidenced by a certificate that will specify the number of Units and the terms designated as applicable to that Award by the Committee in accordance with Section 5(a) above, a form of which shall be made an Exhibit to this Plan. (c) The amount exchanged for the Units during a Redemption Period will be equal to the Redemption Value times the number of Units being exchanged. The Corporation shall pay the Redemption Value for Units from its general assets. Payments will be made in a single lump sum cash payment during the Redemption Period or as soon as practicable thereafter.

ADJUSTMENTS ----------- (a) If there shall be any significant change affecting the outstanding number of shares of the Corporation's common stock through merger, consolidation, reorganization, recapitalization, stock dividend, stock split or combination, or otherwise, the Committee may make 3 LONG TERM PERFORMANCE INCENTIVE COMPENSATION PLAN - ------------------------------------------------- appropriate proportional adjustments to the aggregate number of Units or such terms described in Section 5(a) as is necessary to be consistent with the purposes of this Plan. (b) In the event that there is an unusual nonrecurring event or events that significantly affects the Corporation's Earnings Per Share in a particular year, the Committee may in its sole discretion, consistent with the purposes of the Plan and subject to ratification by the Board of Directors, make an adjustment to the Earnings Per Share (solely for the purposes of this Plan) so that the Earnings Per Share for the applicable Redemption Period is determined without regard to the nonrecurring event or events. (c) In the event of a proposed dissolution or liquidation of the Corporation, each Unit awarded under the Plan shall terminate as of a date, to be fixed by the Committee. At least thirty (30) days' written notice of the date so fixed shall be given to each Employee awarded Units (or other person entitled to exercise the Unit). During the period of thirty (30) days preceding such termination, all outstanding Units shall be exchanged for the Redemption Value paid for Units in that Award in the immediately preceding Redemption Period applicable to that Award, or if the date for exchange would fall within a Redemption Period, the Redemption Value applicable to that Award in that Redemption Period, or if there has not yet been a Redemption Period for such Units, the Redemption Value will be $1.00 per Unit. The right to exchange Units shall apply to all Units, including those which would not otherwise be vested. (d) In the event of a Change of Control, all Units, including Units which are not yet vested, shall, within sixty (60) days of the Change of Control, be exchanged for a Redemption Value based upon using 200% of the Base Earnings Per Share applicable to each Award as the Earnings Per Share.

(ii) The Corporation is merged or consolidated with another corporation and, as a result of such merger or consolidation, less than 75% of the outstanding voting securities of the surviving or resulting corporation shall then be owned in the aggregate by the former stockholders of the Corporation, other than affiliates within the meaning of the Securities Exchange Act of 1934 (the "Exchange Act") or any 4 LONG TERM PERFORMANCE INCENTIVE COMPENSATION PLAN - ------------------------------------------------- party to such merger or consolidation. (iii) The Corporation transfers substantially all of its assets to another corporation or entity which is not a wholly owned Subsidiary of the Corporation. 5 LONG TERM PERFORMANCE INCENTIVE COMPENSATION PLAN - ------------------------------------------------- (iv) Any "person" (as such term is used in Sections 3(a)(9) and 13(d)(3) of the Exchange Act) is or becomes the beneficial owner, directly or indirectly, of securities of the Corporation representing 25% or more of the combined voting power of the Corporation's then outstanding securities, and the effect of such ownership is to take over and control the affairs of the Corporation. (v) As the result of a tender offer, merger, consolidation, sale of assets, or contested election, or any combination of such transactions, the persons who were members of the Board of Directors of the Corporation immediately before the transaction, cease to constitute at least a majority thereof. (e) In the event that a transaction occurs that would be a Change of Control under Section 6(d) but for the fact that the transaction was approved by the affirmative vote of two-thirds of the Continuing Directors (as that term in hereinafter defined), each Unit including those not yet vested, shall within sixty (60) days of the effective date of the transaction, be exchanged for an amount to be determined by the Committee. (f) For the purposes of this Section, the term "Continuing Directors" shall mean a Director who either (a) was a member of the Board of Directors of the Corporation immediately prior to the Change in Control; or (b) was designated (before his or her election as director) as a Continuing Director by a majority of the then Continuing Directors. 7.

(b) If a Participant retires from the Corporation prior to reaching age 65 but on or after reaching age 55, then (i) Units which are not vested on the effective date of such retirement shall expire upon such retirement and (ii) those Units which are vested on the effective date of such retirement shall be exchanged during the earliest Redemption Period applicable to that Award which is coincident with or following the date of retirement; provided, however, that, in the sole discretion of the Chief Executive Officer, Units which are not otherwise vested may become vested.
