          Martin Marietta Materials, Inc., a corporation organized and existing

of amending its articles of incorporation to fix the preferences, limitations
and relative rights of a series of a class of its shares:

          1. The name of the Corporation is MARTIN MARIETTA MATERIALS, INC.

          2. Pursuant to the authority conferred upon the Board of Directors by
Article 2 of the Articles of Incorporation of this Corporation and in accordance

2




          (A) Subject to the prior and superior rights of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Class A Preferred Stock with respect to dividends, the holders of shares of
Class A Preferred Stock shall be entitled to receive, when, as and if declared
by the Board of Directors out of funds legally available for the purpose,
quarterly dividends payable in cash on the first day of January, April, July and
October in each year (each such date being referred to herein as a "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or fraction of a share of Class A Preferred
Stock, in an amount per share (rounded to the nearest cent), subject to the
provision for adjustment hereinafter set forth, equal to 1000 times the
aggregate per share amount of all cash dividends, and 1000 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock, par value $.01 per share, of the
Corporation (the "Common Stock") since the immediately preceding Quarterly
Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Class A
Preferred Stock. In the event the Corporation shall at any time (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount to which holders of
shares of Class A Preferred Stock were entitled immediately prior to such event
under clause (b) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

          (B) The Corporation shall declare a dividend or distribution on the
Class A Preferred Stock as provided in paragraph (A) above immediately after it
declares a dividend or distribution on the Common Stock (other than a dividend
payable in shares of Common Stock).

          (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Class A Preferred Stock from the Quarterly Dividend Payment Date next
preceding the date of issue of such shares of Class A Preferred Stock, unless
the date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such shares shall
begin to accrue from the date of issue of such shares, or unless the date of
issue is a Quarterly Dividend Payment Date or is a date after the record date
for the determination of holders of shares of Class A Preferred Stock entitled
to receive a quarterly dividend and before such



                                       2
3




Quarterly Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Class A Preferred Stock in an amount less than the total amount of
such dividends at the time accrued and payable on such shares shall be allocated
pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Class A Preferred Stock entitled to receive payment of a
dividend or distribution declared thereon, which record date shall be no more
than thirty (30) days prior to the date fixed for the payment thereof.

          Section 3. Voting Rights. The holders of shares of Class A Preferred
Stock shall have the following voting rights:

          (A) Subject to the provision for adjustment hereinafter set forth,
each share of Class A Preferred Stock shall entitle the holder thereof to 1000
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time (i) declare any dividend on
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
Common Stock, or (iii) combine the outstanding Common Stock into a smaller
number of shares, then in each such case the number of votes per share to which
holders of shares of Class A Preferred Stock were entitled immediately prior to
such event shall be adjusted by multiplying such number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

          (B) Except as otherwise provided herein or by law, the holders of
shares of Class A Preferred Stock and the holders of shares of Common Stock
shall vote together as one class on all matters submitted to a vote of
stockholders of the Corporation.

          (C) (i) If at any time dividends on any Class A Preferred Stock shall
be in arrears in an amount equal to four (4) quarterly dividends thereon, the
occurrence of such contingency shall mark the beginning of a period (herein
called a "default period") which shall extend until such time when all accrued
and unpaid dividends for all previous quarterly dividend periods and for the
current quarterly dividend period on all shares of Class A Preferred Stock then
outstanding shall have been declared and paid or set apart for payment. During
each default period, all holders of Preferred Stock (including holders of the
Class A Preferred Stock) with dividends in arrears in an amount equal to four
(4) quarterly dividends thereon, voting as a class, irrespective of series,
shall have the right to elect two (2) Directors.





                                       3
4




          (ii) During any default period, such voting right of the holders of
Class A Preferred Stock may be exercised initially at a special meeting called
pursuant to subparagraph (iii) of this Section 3(C) or at any annual meeting of
stockholders, and thereafter at annual meetings of stockholders, provided that
neither such voting right nor the right of the holders of any other series of
Preferred Stock, if any, to increase, in certain cases, the authorized number of
Directors shall be exercised unless the holders of ten percent (10%) in number
of shares of Preferred Stock outstanding shall be present in Person or by proxy.
The absence of a quorum of the holders of Common Stock shall not affect the
exercise by the holders of Preferred Stock of such voting right. At any meeting
at which the holders of Preferred Stock shall exercise such voting right
initially during an existing default period, they shall have the right, voting
as a class, to elect Directors to fill such vacancies, if any, in the Board of
Directors as may then exist up to two (2) Directors or, if such right is
exercised at an annual meeting, to elect two (2) Directors. If the number which
may be so elected at any special meeting does not amount to the required number,
the holders of the Preferred Stock shall have the right to make such increase in
the number of Directors as shall be necessary to permit the election by them of
the required number. After the holders of the Preferred Stock shall have
exercised their right to elect Directors in any default period and during the
continuance of such period, the number of Directors shall not be increased or
decreased except by vote of the holders of Preferred Stock as herein provided or
pursuant to the rights of any equity securities ranking senior to or pari passu
with the Class A Preferred Stock.

          (iii) Unless the holders of Preferred Stock shall, during an existing
default period, have previously exercised their right to elect Directors, the
Board of Directors may order, or any stockholder or stockholders owning in the
aggregate not less than ten percent (10%) of the total number of shares of
Preferred Stock outstanding, irrespective of series, may request, the calling of
a special meeting of the holders of Preferred Stock, which meeting shall
thereupon be called by the President, a Vice-President or the Secretary of the
Corporation. Notice of such meeting and of any annual meeting at which holders
of Preferred Stock are entitled to vote pursuant to this paragraph (C)(iii)
shall be given to each holder of record of Preferred Stock by mailing a copy of
such notice to him at his last address as the same appears on the books of the
Corporation. Such meeting shall be called for a time not earlier than twenty
(20) days and not later than sixty (60) days after such order or request or in
default of the calling of such meeting within sixty (60) days after such order
or request, such meeting may be called on similar notice by any stockholder or
stockholders owning in the aggregate not less than ten percent (10%) of the
total number of shares of Preferred Stock outstanding. Notwithstanding the
provisions of this paragraph (C)(iii), no such special meeting shall be called
during the period within sixty (60) days



                                       4
5




immediately preceding the date fixed for the next annual meeting of the
stockholders.

          (iv) In any default period, the holders of Common Stock, and other
classes of stock of the Corporation if applicable, shall continue to be entitled
to elect the whole number of Directors until the holders of Preferred Stock
shall have exercised their right to elect two (2) Directors voting as a class,
after the exercise of which right (x) the Directors so elected by the holders of
Preferred Stock shall continue in office until their successors shall have been
elected by such holders or until the expiration of the default period, and (y)
any vacancy in the Board of Directors may (except as provided in paragraph
(C)(ii) of this Section 3) be filled by vote of a majority of the remaining
Directors theretofore elected by the holders of the class of stock which elected
the Director whose office shall have become vacant. References in this paragraph
(C) to Directors elected by the holders of a particular class of stock shall
include Directors elected by such Directors to fill vacancies as provided in
clause (y) of the foregoing sentence.

          (v) Immediately upon the expiration of a default period, (x) the right
of the holders of Preferred Stock as a class to elect Directors shall cease, (y)
the term of any Directors elected by the holders of Preferred Stock as a class
shall terminate, and (z) the number of Directors shall be such number as may be
provided for in the articles of incorporation or by-laws irrespective of any
increase made pursuant to the provisions of paragraph (C)(ii) of this Section 3
(such number being subject, however, to change thereafter in any manner provided
by law or in the articles of incorporation or by-laws). Any vacancies in the
Board of Directors effected by the provisions of clauses (y) and (z) in the
preceding sentence may be filled by a majority of the remaining Directors.

          (D) Except as set forth herein, holders of Class A Preferred Stock
shall have no special voting rights and their consent shall not be required
(except to the extent they are entitled to vote with holders of Common Stock as
set forth herein) for taking any corporate action.

          Section 4. Certain Restrictions.

          (A) Whenever quarterly dividends or other dividends or distributions
payable on the Class A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Class A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:

                (i) declare or pay  dividends  on, make any other  distributions
        on, or redeem or purchase or  otherwise  acquire for  consideration  any
        shares of stock ranking junior (either



                                       5
6




        as to dividends or upon liquidation, dissolution or winding up) to the
        Class A Preferred Stock;

                (ii) declare or pay dividends on or make any other distributions
        on any shares of stock  ranking on a parity  (either as to  dividends or
        upon liquidation,  dissolution or winding up) with the Class A Preferred
        Stock,  except dividends paid ratably on the Class A Preferred Stock and
        all such parity  stock on which  dividends  are payable or in arrears in
        proportion  to the total amounts to which the holders of all such shares
        are then entitled;

                (iii) redeem or purchase or otherwise  acquire for consideration
        shares of any stock ranking on a parity  (either as to dividends or upon
        liquidation,  dissolution  or  winding  up) with the  Class A  Preferred
        Stock, provided that the Corporation may at any time redeem, purchase or
        otherwise acquire shares of any such parity stock in exchange for shares
        of any stock of the  Corporation  ranking junior (either as to dividends
        or upon dissolution, liquidation or winding up) to the Class A Preferred
        Stock;

                (iv) purchase or otherwise  acquire for consideration any shares
        of Class A Preferred  Stock,  or any shares of stock ranking on a parity
        with the Class A Preferred  Stock,  except in accordance with a purchase
        offer made in writing or by  publication  (as determined by the Board of
        Directors) to all holders of such shares upon such terms as the Board of
        Directors,  after  consideration of the respective annual dividend rates
        and other relative rights and  preferences of the respective  series and
        classes, shall determine in good faith will result in fair and equitable
        treatment among the respective series or classes.

          (B) The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

          Section 5. Reacquired Shares. Any shares of Class A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock and may be reissued as part of a new series of Preferred Stock
to be created by resolution or resolutions of the Board of Directors, subject to
the conditions and restrictions on issuance set forth herein.

          Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any
liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to



                                       6
7




the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Class A Preferred Stock unless,
prior thereto, the holders of shares of Class A Preferred Stock shall have
received $10.00 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment.
Thereafter, the holders of the Class A Preferred Stock shall be entitled to
receive an aggregate amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1000 times the aggregate amount to be
distributed per share to holders of shares of Common Stock. Following the
payment of the foregoing, holders of Class A Preferred Stock and holders of
shares of Common Stock shall receive their ratable and proportionate share of
the remaining assets to be distributed.

          (B) In the event, however, that there are not sufficient assets
available to permit payment in full of the Class A Preferred Stock liquidation
preference and the liquidation preferences of all other series of preferred
stock, if any, which rank on a parity with the Class A Preferred Stock, then
such remaining assets shall be distributed ratably to the holders of such parity
shares in proportion to their respective liquidation preferences.

          (C) In the event the Corporation shall at any time (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock (by reclassification or otherwise), or (iii) combine
the outstanding Common Stock into a smaller number of shares, then in each such
case the aggregate amount to which holders of shares of the Class A Preferred
Stock were entitled immediately prior to such event shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

          Section 7. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Class A Preferred Stock shall at the same time be similarly exchanged or changed
in an amount per share (subject to the provision for adjustment hereinafter set
forth) equal to 1000 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is changed or exchanged. In the event the
Corporation shall at any time (i) declare any dividend on Common Stock payable
in shares of Common Stock, (ii) subdivide the outstanding Common Stock (by
reclassification or otherwise), or (iii) combine the outstanding Common Stock
into a smaller number of shares, then in each such case the amount set forth in
the preceding sentence with respect to the exchange or



                                       7
8




change of shares of Class A Preferred Stock shall be adjusted by multiplying
such amount by a fraction the numerator of which is the number of shares of
Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately
prior to such event.

          Section 8. No Redemption. The shares of Class A Preferred Stock shall
not be redeemable.

          Section 9. Ranking. The Class A Preferred Stock shall rank junior to
all other series of the Corporation's Preferred Stock as to the payment of
dividends and the distribution of assets, unless the terms of any such series
shall provide otherwise.

          Section 10. Amendment. The Articles of incorporation, as amended, of
the Corporation shall not be further amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Class A Preferred Stock so as to affect them adversely without the affirmative
vote of the holders of a majority or more of the outstanding shares of Class A
Preferred Stock voting separately as a class.

          Section 11. Fractional Shares. Class A Preferred Stock may be issued
in fractions of a share which shall entitle the holder, in proportion to such
holder's fractional shares, to exercise voting rights, receive dividends,
participate in distributions and to have the benefit of all other rights of
holders of Class A Preferred Stock.

          3. The date on which the foregoing amendment to the Articles of
Incorporation of the Corporation was adopted was July 23, 1996.

          4. The foregoing amendment to the Articles of Incorporation was duly
adopted by the Board of Directors of the Corporation, and shareholder action was
not required to adopt such amendment because the Articles of Incorporation
permit the Board of Directors to fix designations, preferences, limitations and
relative rights of series of the Corporation's preferred stock without
shareholder approval and Section 55-6-02 of the North Carolina Business
Corporation Act provides that articles of amendment so establishing the
preferences, limitations or relative rights of a class or series of stock are
effective without shareholder action.




                                       8

          5. These Articles of Amendment shall be effective at 8:01 a.m. (EDT)
on the date of filing of these Articles of Amendment with the Secretary of State
of North Carolina.

          IN WITNESS WHEREOF, the undersigned has executed and subscribed this
Articles of Amendment on this the 18th day of October, 1996.
