                         MARTIN MARIETTA MATERIALS, INC.


     1.  The name of the corporation is Martin Marietta Materials, Inc.
(hereinafter the "Corporation").

     2.  The number of shares the Corporation is authorized to issue is One
Hundred Ten Million (110,000,000), divided into One Hundred Million
(100,000,000) Common Shares and Ten Million (10,000,000) Preferred Shares, each
with a par value of one cent ($.01) per share.

The  preferences,  limitations  and relative  rights of each class and series of
shares are as follows:

         (a)  Common Shares
              -------------

              The common shares shall be entitled to one vote per share and to
              all other rights of shareholders subject only to any rights
              granted to Preferred Shares under subparagraph (b) of this Article
              2.

         (b)  Preferred Shares
              ----------------

              The Preferred Shares may be issued in one or more series with such
              designations, preferences, limitations, and relative rights as the
              board of directors may determine from time to time in accordance
              with applicable law.

     3.  The address of the registered office of the Corporation in the State of
North Carolina is 225 Hillsborough Street, Raleigh, Wake County, North Carolina
27603; and the name of its registered agent at such address is CT Corporation
System.

     4.  The name and address of the incorporator are Russell M. Robinson, II,
1900 Independence Center, Charlotte, Mecklenburg County, North Carolina 28246.

     5.  (a) The number of directors of the Corporation shall be not less than
nine (9) nor more than eleven (11). By vote of a majority of the Board of
Directors or shareholders of the Corporation, the number of directors of the
Corporation may be increased or decreased, from time to time, within the range
above specified; provided, however, that the tenure of office of a director
shall not be affected by any decrease in the number of directors so made by the
Board or the shareholders.

             (b)(i) The directors shall be divided into three classes,
             designated Class I, Class II and Class III. Each class shall
             consist, as nearly as may






2

             be possible, of one-third of the total number of directors
             constituting the Board of Directors. Prior to the 1997 annual
             meeting of shareholders, the Board of Directors shall determine
             which directors shall be designated as Class I, Class II and Class
             III directors. The term of the initial Class I directors shall
             terminate on the date of the 1997 annual meeting of shareholders;
             the term of the initial Class II directors shall terminate on the
             date of the 1998 annual meeting of shareholders; and the term of
             the initial Class III directors shall terminate on the date of the
             1999 annual meeting of shareholders. At each annual meeting of
             shareholders beginning in 1997, successors to the class of
             directors whose term expires at that annual meeting shall be
             elected for a three-year term. Those persons who receive the
             highest number of votes at a meeting at which a quorum is present
             shall be deemed to have been elected.

       (ii)  If the number of directors is changed, any increase or decrease
             shall be apportioned among the classes so as to maintain the number
             of directors in each class as nearly equal as possible, but in no
             case will a decrease in the number of directors shorten the term of
             any incumbent director. A director shall hold office until the
             annual meeting for the year in which his or her term expires and
             until his or her successor shall be elected and shall qualify,
             subject, however, to prior death, resignation, retirement,
             disqualification or removal from office.

       (iii) Notwithstanding the foregoing, whenever the holders of any one or
             more classes or series of Preferred Shares issued by the
             Corporation shall have the right, voting separately by class or
             series, to elect directors at an annual or special meeting of
             shareholders, the election, term of office, filling of vacancies
             and other features of such directorships shall be governed by the
             terms of these Restated Articles of Incorporation or the resolution
             or resolutions adopted by the Board of Directors pursuant to
             Article 2(b) of these Restated Articles of Incorporation applicable
             thereto, and such directors so elected shall not be divided into
             classes pursuant to this Article 5(b) unless expressly provided by
             the terms of such Preferred Shares.

     (c)  Vacancies in the Board of Directors, except for vacancies resulting
from an increase in the number of directors, shall be filled only by a majority
vote of the remaining



                                       2
3

directors then in office, though less than a quorum, except that vacancies
resulting from removal from office by a vote of the shareholders may be filled
by the shareholders at the same meeting at which such removal occurs. Vacancies
resulting from an increase in the number of directors shall be filled only by a
majority vote of the Board of Directors. Any director elected to fill a vacancy
shall hold office until the next shareholders' meeting at which directors are
elected. No decrease in the number of directors constituting the Board of
Directors shall affect the tenure of any incumbent director.

     (d)  Except as otherwise provided herein, any of the directors or the
entire Board of Directors, as the case may be, may be removed at any time, but
only for cause, by a vote of the shareholders and if the number of votes cast
to remove such director(s) or the entire Board of Directors, as the case may
be, exceeds the number of votes cast not to remove such director(s) or the
entire Board of Directors, as the case may be. Cause for removal shall be
deemed to exist only if the director(s) whose removal is proposed has been
convicted in a court of competent jurisdiction of a felony or has been adjudged
by a court of competent jurisdiction to be liable for fraudulent or dishonest
conduct, or gross abuse of authority or discretion, with respect to the
Corporation, and such conviction or adjudication has become final and
non-appealable. If a director is elected by a voting group of shareholders,
only the shareholders of that voting group may participate in the vote to
remove such director. A director may not be removed by the shareholders at a
meeting unless the notice of the meeting states the purpose, or one of the
purposes, of the meeting is removal of the director.  If any directors are so
removed, new directors may be elected at the same meeting.

     6.  To the fullest extent permitted by the North Carolina Business
Corporation Act as it exists or may hereafter be amended, no person who is
serving or who has served as a director of the Corporation shall be personally
liable to the Corporation or any of its shareholders for monetary damages for
breach of duty as a director. No amendment or repeal of this Article, nor the
adoption of any provision to these Restated Articles of Incorporation
inconsistent with this Article, shall eliminate or reduce the protection
granted herein with respect to any matter that occurred prior to such
amendment, repeal or adoption.

     7.  The provision of Article 9 of the North Carolina Business Corporation
Act entitled "The North Carolina Shareholder Protection Act" and of Article 9A
entitled "The North Carolina Control Share Acquisition Act" shall not be
applicable to the Corporation.

     8.  (a) Any purchase by the Corporation of shares of Voting Stock (as
hereinafter defined) from an Interested Shareholder (as hereinafter defined)
who has beneficially owned



                                       3

or any agreement in respect thereof, other than pursuant to an offer to the
holders of all of the outstanding  shares of the same class as those so
purchased,  at a per share price in excess of the Market Price (as hereinafter
defined),  at the time  of such  purchase  or any  agreement  in  respect
thereof  (whichever  is earlier), of the shares so purchased,  shall require
the affirmative vote of the holders of a majority of the voting power of the
Voting  Stock not  beneficially owned by the Interested Shareholder, voting
together as a single class.

     (b)  In addition to any affirmative vote required by law or these Restated
Articles of Incorporation:

                Subsidiary (as hereinafter defined) with (i) any Interested
                Shareholder or (ii) any other corporation (whether or not
                itself an Interested Shareholder) which is, or after such
                merger or consolidation would be, an Affiliate (as hereinafter
                defined) of an Interested Shareholder;

          (ii)  Any sale, lease, exchange, mortgage, pledge, transfer, or other
                disposition (in one transaction or a series of transactions) to
                or with any Interested Shareholder or any Affiliate of any
                Interested Shareholder of any assets of the Corporation or any
                Subsidiary having an aggregate Fair Market Value (as
                hereinafter defined) of $10,000,000 or more;

          (iii) The issuance or transfer by the Corporation or any Subsidiary

                Shareholder in exchange for cash, securities, or other property
                (or combination thereof);

          (iv)  The adoption of any plan or proposal for the liquidation or
                dissolution of the Corporation proposed by or on behalf of an
                Interested Shareholder or any Affiliate of any Interested
                Shareholder; or

          (v)   Any reclassification of securities (including any reverse stock
