                     THE MARTIN MARIETTA MATERIALS, INC.
                     SHAREHOLDER VALUE ACHIEVEMENT PLAN

INTRODUCTION

     The Martin Marietta Materials, Inc. Shareholder Value Achievement Plan
(the "Plan") is designed to foster and promote the long-term growth and
performance of the Company by enhancing the Company's ability to attract and
retain qualified key employees and motivating key employees through stock
ownership and performance-based incentives, and to more closely align the goals
of such employees with that of the Company's shareholders.  To achieve this
purpose, this Plan provides authority for the grant of performance-based stock
awards.

faith and without reasonable belief that his action or omission was in the best
interest of the Company.

amended (the "Exchange Act")) (a "Person") of beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act) of 40% or more of

Common Stock"), or (ii) the combined voting power of the then outstanding

directors (the "Outstanding Company Voting Securities"); provided, however,
that for purposes of this subsection (a), the following acquisitions shall not
constitute a Change of Control: (A) any acquisition by the Company or any

director subsequent to such effective date whose election, or nomination for
election by the Company's shareholders, was approved by a vote of at least a
majority of the directors then comprising the Incumbent Board shall be
considered as though such individual were a member of the Incumbent Board, but
excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an actual or threatened election contest with

solicitation of proxies or consents by or on behalf of a Person other than the
Board; or

of, respectively, the then outstanding shares of common stock and the combined
voting power of the then outstanding voting securities entitled to vote

assets either directly or through one or more subsidiaries) in substantially
the same proportions as their ownership, immediately prior to such Business
Combination, of the Outstanding Company Common Stock and Outstanding Company
Voting Securities, as the case may be, and (ii) no Person (excluding any
employee benefit plan (or related trust) sponsored or maintained by the Company
or any Affiliate of the Company, or such corporation resulting from such
Business Combination or any Affiliate of such corporation) beneficially owns,

any applicable waiting period).  If the Company does not maintain a long-term
disability program, or if a Participant does not elect coverage under such
program, Disability shall mean the incapacity of the Participant such that he

   5

benefits from the Company's qualified defined benefit retirement plan or (b) if

ARTICLE 2 - ELIGIBILITY

     All key employees of the Company and any of its direct or indirect
subsidiaries, including officers whether or not members of the Board of
Directors, are eligible for the grant of Awards. The selection of key employees
to receive Awards will be within the discretion of the Committee.

ARTICLE 3 - COMMON STOCK AVAILABLE FOR AWARDS; ADJUSTMENT

     3.1 Number of Shares of Common Stock.  Subject to adjustment as provided
for in Section 3.3, the aggregate number of shares of Common Stock that may be
subject to Awards granted under this Plan shall be 250,000 shares of Common
Stock.  The assumption of awards granted by an organization acquired by the
Company, or the grant of Awards under this Plan in substitution of any such
awards, will not reduce the number of shares of Common Stock available for the
grant of Awards under this Plan.

     Common Stock subject to an Award that expires or is forfeited, terminated,
or canceled will again be available for grant under this Plan, without reducing
the number of shares of Common Stock available for grant of Awards under this
Plan.

     3.2 No Fractional Shares.  No fractional shares of Common Stock will be
issued under the Plan, and the Committee will round the number of shares to
which a Participant is entitled down to the nearest whole share.



                                      5

   6

     3.3 Adjustment.  The aggregate number of shares of Common Stock which may
be issued pursuant to Awards granted hereunder, the number of shares of Common
Stock covered by each outstanding Award and the price per share thereof shall
be appropriately adjusted for any increase or decrease in the number of
outstanding shares of Common Stock resulting from a stock split or other
subdivision or consolidation of shares of Common Stock or for other capital
adjustments or payments of stock dividends or distributions or other increases
or decreases in the outstanding shares of Common Stock without receipt of
consideration by the Company.

     In the event of any change in the outstanding shares of Common Stock by
reason of any recapitalization, merger, consolidation, spin-off, combination or
exchange of shares or other corporate change, or any distributions to common
shareholders other than cash dividends, the Committee shall make such
substitution or adjustment, if any, as it deems to be equitable, as to the
number or kind of shares of Common Stock or other securities issued or reserved
for issuance pursuant to the Plan, and the number or kind of shares of Common
Stock or other securities covered by outstanding Awards, and the price thereof.
In instances where another corporation or other business entity is being
acquired by the Company, and the Company has assumed outstanding employee award
grants and/or the obligation to make future or potential grants under a prior
existing plan of the acquired entity, similar adjustments are permitted at the
discretion of the Committee.  The adjustments provided for in this Section 3.3,
and the manner of their application, shall be determined by the Committee in
its sole discretion.

ARTICLE 4 - ADMINISTRATION

     4.1 Committee.  This Plan will be administered by the Committee.  The
Committee will, subject to the terms of this Plan, have the authority to (a)
select the eligible employees who will receive Awards, (b) grant Awards, (c)
determine the number of Awards to be granted to Participants, (d) determine the
terms, conditions, and restrictions applicable to Awards (including the
establishment of Performance Goals pursuant to Section 5.3), (e) adopt, alter,
and repeal administrative rules and practices governing this Plan, (f)
interpret the terms and provisions of this Plan and any Awards granted under
this Plan, (g) prescribe the forms of any Award Agreement, or other instruments
relating to Awards, and (h) otherwise supervise the administration of this 


                                      6

   7

Plan and exercise such rights and responsibilities as are delegated to it
thereunder.  All decisions by the Committee will be made with the approval of
not less than a majority of its members.                                   

     4.2 Delegation.  The Committee may delegate any of its authority to any
other person or persons that it deems appropriate, provided the delegation does
not cause this Plan or any Awards granted under this Plan to fail to qualify
for the exemption provided by Rule 16b-3 or Section 162(m).

     4.3 Decisions Final.  All decisions by the Committee, and by any other
person or persons to whom the Committee has delegated authority, will be final
and binding on all persons.

ARTICLE 5 - AWARDS

     5.1 General.  The Committee may, in its discretion, grant to Participants
Awards valued by reference to shares of Common Stock that are wholly contingent
on the attainment of performance goals established by the Committee in
accordance with the terms of this Plan.

     5.2 Grant of Awards.  (a) Awards shall be granted to Participants as of
the beginning of a Measurement Period.  The payment with respect to the Awards
shall be conditioned on the satisfaction of the performance goals described in
Section 5.3 at the end of the applicable Measurement Period.  Once established,
the Committee shall not have discretion to modify the terms of the Awards
except with respect to any discretion specifically granted to the Committee
under this Plan.  It is intended that all payments hereunder to Participants
will satisfy the requirements for the exemption under Section 162(m) and
related regulations for "qualified performance-based compensation."

     (b) Not later than 90 days after the beginning of the Measurement Period
(or, if earlier, the date on which 25% of the Measurement Period has elapsed),
the Committee shall grant a specified number of Awards to each Participant with
respect to that Measurement Period.  No Participant may be granted Awards with
respect to a Measurement Period having as a target amount in excess of the
lesser of (i) an aggregate of 20,000 shares of Common Stock or (ii) a dollar
value of $500,000 based on the Fair Market Value of the target number of shares
of Common Stock 



                                      7

   8

subject thereto on the first day of the applicable Measurement Period.         

     (c) At the end of the Measurement Period, the Committee shall determine
the percentage, if any, of the Awards granted to the Participant for that
Measurement Period that are earned by the Participant.  That percentage shall
be based on the degree to which the performance goals for that Measurement
Period are satisfied.  The formula for determining the correlation between the
percentage of the Awards earned and the level of performance for a Measurement
Period shall be established in writing by the Committee at the time the
performance goals are determined.  Prior to the payment of any Awards, the
Committee must certify in writing the degree of attainment of the applicable
performance goals.

     5.3 Performance Goals.  Performance goals used to compute Awards shall be
adopted by the Committee in writing prior to the grant of any Awards to which
such performance goals apply.  The performance goals shall be based on one or
more of the following performance measures:  (a) total return to shareholders,
(b) cash flow, (c) return on equity, (d) return on assets, (e) stock price, and
(f) earnings per share.  Any such performance goals and the applicable
performance measures will be reflected in each Award Agreement to which such
goals and measures relate.  The number of Awards that will be paid out to any
Participant at the end of the applicable Measurement Period will depend on the
extent to which the Company attains the established performance goals, as
established pursuant to Section 5.2(c).

     5.4 Nonforfeitability of the Award.  (a)  General.  Except as provided in
Section 5.4(b) and (c) and Article 6, a Participant must remain employed by the
Company until the end of a Measurement Period to receive payment with respect
to any Award.

     (b) Death or Disability.  Subject to Section 5.4(d), if during a
Measurement Period a Participant terminates employment on account of death or
Disability, (together, a "Qualifying Termination"), such Participant (or in the
case of death, his estate) shall be entitled to a prorated payment with respect
to Awards held by the Participant with respect to that Measurement Period, as
described in the next sentence.  The Participant shall be entitled to payment
with respect to a percentage of such 



                                      8

   9

Awards as set forth below based on the Fiscal Year during the Measurement
Period in which his Qualifying Termination occurs:




                           FISCAL YEAR  PERCENTAGE  
                           -----------  ----------  
                                     
                                  1st   0%          
                                  2nd   33-1/3%     
                                  3rd   66-2/3%     


For purposes of determining the payment with respect to a Participant's Awards
under this Section 5.4(b), it shall be assumed that the Company has achieved
the target level of performance it established for the Measurement Period.  If
the Measurement Period is other than three Fiscal Years, then the Committee
shall make appropriate adjustments to the above schedule in its sole
discretion.

Payment with respect to Awards under this Section 5.4(b), if any, will be made
as soon as practicable after the Participant's Qualifying Termination occurs.

     (c) Retirement and Certain Terminations.  Subject to Section 5.4(d), if a
Participant holding Awards terminates employment on account of Retirement, or
is involuntarily terminated by the Company without Cause before the end of the
applicable Measurement Period, the Participant shall be entitled to payment
with respect to such Awards at the end of such Measurement Period as if he had
remained employed until that time.

     (d) Committee Negative Discretion. The Committee may, in its sole
discretion, decide to reduce or eliminate any amount otherwise payable with
respect to an Award under Section 5.4(b) or (c).

     5.5 Payment of the Award.  A Participant's Award shall be paid as soon as
practicable after the end of the Measurement Period (or, in the case of a
Participant who dies or incurs a Disability and becomes entitled to payment
with respect to an Award pursuant to Section 5.4(b), as soon as practicable
following death or the determination of Disability).  Payment shall be made in
shares of Common Stock or, in the discretion of the Committee, all or in part
cash, based on the Fair Market Value of the applicable number of shares of
Common Stock on the payment date.



                                      9

   10

ARTICLE 6 - CHANGE OF CONTROL

     6.1 Effect of Change of Control.  Notwithstanding any provision of this
Plan to the contrary, in the event that a Change of Control occurs, all
conditions applicable to outstanding Awards will be deemed to have been
satisfied at the target level as of the date of the Change of Control.  Payment
with respect to such Awards shall be made as soon as practicable after the
Change of Control in accordance with the last sentence of Section 5.5.

ARTICLE 7 - GENERAL

     7.1 Nonassignability of Awards.  No right or interest of a Participant
under the Plan shall be subject in any manner to anticipation, alienation,
sale, assignment, transfer, encumbrance, pledge, attachment, garnishment by
creditors of the Participant or his successors, or shall be transferable by a
Participant otherwise than by will or the laws of intestate succession.  Any
attempt to take an action with respect to an Award which is prohibited by the
preceding sentence shall render such Award null and void.

     7.2 No Right or Obligation of Continued Employment.  Nothing contained in
this Plan shall require the Company or a related company to continue to employ
a Participant, nor shall the Participant be required to remain in the
employment of the Company or a related company.

     7.3 Withholding.  The Company shall withhold all required local, state and
federal taxes from any amount payable in respect of an Award, including
withholding of shares of Common Stock otherwise payable pursuant to the Plan.

     7.4 Effective Date.  This Plan shall be effective as of the latest to
occur of (a) approval by the Company's shareholders and (b) the distribution by
Lockheed Martin Corporation of such number of shares of Common Stock which
results in Lockheed Martin Corporation no longer owning, directly or
indirectly, more than fifteen percent (15%) of the outstanding Common Stock
(the "Split-Off").  If both of the above conditions do not occur by December
31, 1997, all Awards previously granted shall become null and void.  Moreover,
no payment shall be made to a Participant pursuant to an Award prior to such
shareholder 



                                     10

   11


approval being obtained and the Split-Off having occurred.  This Section 7.4
shall supersede any other provision of the Plan.
            
     7.5 Amendment and Termination of the Plan.  The Plan may be amended or
terminated at any time by the Board of Directors or by the Committee as
delegated by the Board of Directors, provided that such termination or
amendment shall not, without the consent of the Participant, adversely affect
such Participant's rights with respect to Awards previously awarded to him.
Shareholder approval for any amendment is required to the extent necessary to
preserve the exemption for "qualified performance-based compensation" under
Section 162(m).  With the consent of the Participant affected, the Board of
Directors, or by delegation of authority by the Board of Directors, the
Committee, may amend outstanding Award Agreements in a manner not inconsistent
with the Plan.

     7.6 Binding on Successors.  The obligations of the Company under the Plan
shall be binding upon any organization which shall succeed to all or
substantially all of the assets of the Company, or into which the Company may
merge, and the term "Company," whenever used in the Plan, shall mean and
include any such organization after the succession.

     7.7 References.  Any masculine personal pronoun shall be considered to
mean also the corresponding feminine or neuter personal pronoun, as the context
requires.

     7.8 Applicable Law.  The Plan shall be governed by and construed in
accordance with the laws of the State of North Carolina.
