Item 5.  Other Events

Adoption of Stockholder Rights Plan

         On  October  15,  1996,  the  Board of  Directors  of  Martin
Marietta Materials,  Inc. (the "Company")  declared a dividend  distribution of
one Right for each  outstanding  share of the Company's  common stock,  par
value $.01 per share (the "Common  Stock"),  payable to  stockholders of record
at the close of business on October 21, 1996 (the "Record  Date") and with
respect to the Common Stock issued  thereafter  until the  Distribution  Date
(defined  below) and, in certain  circumstances,  with  respect  to the  Common
Stock  issued  after the Distribution Date. Each Right, when it becomes
exercisable,  generally entitles the registered  holder to purchase from the
Company a unit consisting  initially of one  one-thousandth  of a share (a
"Unit") of Junior  Participating  Class A Preferred  Stock,  par value  $.01
per share  (the  "Preferred  Stock"),  of the Company,  at a  Purchase  Price
of $100 per Unit,  subject  to  adjustment  (the "Purchase  Price").  The
description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement"), dated as of October 21, 1996, between the Company and
First Union National Bank of North Carolina, as Rights Agent.

         Initially, the Rights will be attached to all certificates
representing shares of Common Stock then outstanding, and no separate
certificates evidencing the Rights ("Rights Certificates") will be distributed.
The Rights will separate from the Common Stock and a Distribution Date will
occur upon the earlier of (i) ten (10) days (or such later  date as the Board
of  Directors  shall  determine) following  public  disclosure that a Person or
group of affiliated or associated Persons has become an "Acquiring  Person" (as
defined  below),  or (ii) ten (10) business  days (or such later date as the
Board of  Directors  shall  determine) following the commencement of a tender
offer or exchange offer that would result in a Person or group becoming an
"Acquiring Person".  Except as set forth below, an "Acquiring  Person" is a
Person or group of affiliated or associated  Persons who has acquired
beneficial  ownership of 15% or more of the outstanding shares of Common Stock.
The term "Acquiring Person" excludes (i) the Company,  (ii) any subsidiary of
the Company, (iii) any employee benefit plan of the Company or any subsidiary
of the Company, and (iv) any Person or entity organized, appointed or
established by the Company for or pursuant to the terms of any such plan.

         Until the occurrence of the  Distribution  Date, (i) the Rights will
be evidenced by the Common Stock certificates and will be transferred with and
only with such Common Stock  certificates,  (ii) new Common Stock certificates
issued after the Record Date will contain a notation incorporating the Rights
Agreement by  reference,  and (iii) the  surrender  for transfer of any
certificates  for Common Stock outstanding will also

3


         constitute the transfer of the Rights  associated with the Common
Stock represented by such certificate.  Pursuant to the Rights Agreement,  the
Company reserves the right to require prior to the occurrence of a Triggering
Event (as defined  below)  that,  upon any  exercise  of  Rights,  a number  of
Rights be exercised so that only whole shares of Preferred Stock will be
issued.

         As soon as practicable  after the occurrence of the Distribution
Date, Rights  Certificates  will be mailed to holders of record of the Common
Stock as of the close of business on the Distribution Date and, thereafter,
the separate Rights  Certificates  alone  will  represent  the  Rights.
Except  in  certain circumstances  specified in the Rights  Agreement or as
otherwise  determined by the  Board of  Directors,  only  shares  of  Common
Stock  issued  prior to the Distribution Date will be issued with Rights.

         The Rights are not exercisable until the occurrence of the
Distribution Date and until the Rights no longer are  redeemable.  The Rights
will expire at the close of business on October 21, 2006,  unless extended or
earlier  redeemed by the Company as described below.

         In the event that,  at any time  following  the  Distribution  Date,
a Person becomes an Acquiring Person,  each holder of a Right will thereafter
have the right to receive,  upon exercise of the Right,  Common Stock (or, in
certain circumstances, cash, property or other securities of the Company)
having a value equal to two times the exercise price of the Right.
Notwithstanding  any of the foregoing,  following the  occurrence of the event
set forth in this  paragraph, all Rights that are, or (under  certain
circumstances  specified  in the Rights Agreement)  were,  beneficially  owned
by any Acquiring  Person will be null and void and  nontransferable  and any
holder  of any  such  right  (including  any purported  transferee  or
subsequent  holder)  will be  unable to  exercise  or transfer any such right.
For example,  at an exercise  price of $100 per Right, each Right not owned by
an  Acquiring  Person (or by  certain  related  parties) following a
Triggering  Event (as defined  below)  would  entitle its holder to purchase
$200 worth of Common Stock (or other consideration, as noted above) for $100.
Assuming that the Common Stock had a per share value of $25 at such time, the
holder of each valid Right would be entitled to purchase 8 (eight) shares of
Common Stock for $100.

         In the event that,  at any time  following  the date on which there
has been public disclosure that, or of facts indicating that, a Person has
become an Acquiring Person (the "Stock Acquisition  Date"), (i) the Company is
acquired in a merger or other business  combination  transaction in which the
Company is not the  surviving  corporation,  or (ii)  50% or more of the
Company's  assets  or earning power is sold, mortgaged or transferred,  each
holder of a Right (except Rights which previously have been voided as set forth
above) shall thereafter

4


         have the right to receive, upon exercise, common stock of the
acquiring company having a value equal to two times the exercise  price of the
Right.  The events set forth in this  paragraph and in the preceding  paragraph
are referred to as the "Triggering Events."

         The purchase price payable,  and the number of Units of Preferred
Stock or other  securities  or  property  issuable,  upon  exercise  of the
Rights are subject to adjustment from time to time to prevent  dilution (i) in
the event of a stock dividend on, or a subdivision,  combination or
reclassification  of, the Preferred  Stock,  (ii) if holders of the  Preferred
Stock are granted  certain rights or warrants to subscribe for Preferred Stock
or convertible securities at less than the current  market price of the
Preferred  Stock,  or (iii) upon the distribution  to holders of the Preferred
Stock of evidences of indebtedness or assets (excluding regular quarterly cash
dividends) or of subscription rights or warrants (other than those referred to
above).

         With certain  exceptions,  no adjustment in the purchase  price will
be required  until  cumulative  adjustments  amount to at least 1% of the
purchase price. No fractional Units will be issued and, in lieu thereof, an
adjustment in cash will be made based on the market price of the  Preferred
Stock on the last trading date prior to the date of exercise.

         Because of the nature of the Preferred  Stock's  dividend,
liquidation and voting rights,  the value of the one  one-thousandth  interest
in a share of Preferred Stock  purchasable upon exercise of each Right should
approximate the value of one share of Common Stock.  Shares of Preferred Stock
purchasable upon exercise of the Rights will not be  redeemable.  Each share of
Preferred  Stock will be  entitled  to a quarterly  dividend  payment of 1000
times the  dividend declared per share of Common Stock. In the event of
liquidation,  each share of Preferred  Stock will be entitled to a $10.00
preference,  and  thereafter  the holders  of the  shares of  Preferred  Stock
will be  entitled  to an  aggregate payment of 1000 times the aggregate payment
made per share of Common Stock. Each share of Preferred  Stock will have 1000
votes,  voting together with the shares of  Common  Stock.  These  rights  are
protected  by  customary   anti-dilution provisions.

         At any time until ten days  following  a Stock  Acquisition  Date,
the Company  may  redeem  the  Rights in  whole,  but not in part,  at a price
(the "Redemption  Price") of $.01 per Right.  The Redemption  Price may be
payable in cash,  Common Stock or other  consideration  deemed  appropriate by
the Board of Directors. Following a Stock Acquisition Date, the redemption of
any Rights must be  approved  by a majority  of the  Continuing  Directors,
and the  Continuing Directors must constitute a majority of the directors then
in office.  Moreover, during the 120-day  period  immediately  following a
change in a majority of the Board of

5


         Directors  as a result of a proxy or consent  solicitation,  the
Rights may only be redeemed if approved by a majority of the  Directors  then
in office who were in office at the commencement of such proxy or consent
solicitation.  A "Continuing  Director"  is (i) any Person who on the Record
Date was a member of the Board of Directors,  while such Person is a member of
the Board,  who is not an Acquiring  Person,  or an Affiliate or Associate of
an Acquiring Person, or a representative  or nominee of an  Acquiring  Person
or of any such  Affiliate or Associate,  or (ii) any Person who  subsequently
becomes a member of the Board, while such Person is a member of the Board, who
is not an Acquiring  Person,  or an Affiliate or Associate of an Acquiring
Person, or a representative or nominee of an Acquiring  Person or of any such
Affiliate or Associate,  if such Person's nomination for election or election
to the Board is recommended or approved by a majority of the Continuing
Directors.  The redemption of the Rights may be made effective  at such  time
and on such  terms  and  conditions  as the  Board  of Directors in its sole
discretion may establish. Immediately following the action of the Board of
Directors  effecting the  redemption  of the Rights,  the Rights will
terminate  and the only right of the  holders of Rights will be to receive the
Redemption Price.

         At any time after the Rights  become  exercisable  for Common  Stock
or other  consideration  of the Company,  the Board of  Directors  may exchange
the Rights,  in whole or in part, at an exchange ratio of one share of Common
Stock, and/or  equity  securities  deemed to have the same value as one share
of Common Stock, per Right, subject to adjustment.

         Until a Right is exercised,  the holder thereof,  as such, will have
no rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive  dividends.  While the distribution of the Rights
will not be taxable to stockholders or to the Company,  stockholders may,
depending upon the circumstances,  recognize taxable income in the event that
the Rights become exercisable  for Common  Stock (or other  consideration)  of
the  Company or for common stock of the acquiring company as set forth above.

         Other than those provisions relating to the principal economic terms
of the Rights,  any of the  provisions  of the Rights  Agreement  may be
amended by resolution of the Company's Board of Directors prior to the
Distribution  Date; provided that,  following a Stock  Acquisition Date, such
resolution is approved by  a  majority  of  the  Continuing  Directors  and
the  Continuing  Directors constitute a majority of the directors  then in
office.  After the  Distribution Date, the provisions of the Rights Agreement
may be amended by resolution of the Company's  Board of  Directors in order to
cure any  ambiguity,  to make changes which do not adversely affect the
interests of holders of Rights  (excluding the interests  of any  Acquiring
Person or its  affiliates  or  associates),  or to shorten or lengthen any time

6


         period under the Rights  Agreement;  provided  that,  following a
Stock Acquisition  Date,  such  resolution is approved by a majority of the
Continuing Directors and the  Continuing  Directors  constitute a majority of
the directors then in office;  and  provided  further,  that no  amendment  to
adjust the time period  governing  redemption  shall be made at such time as
the  Rights are not redeemable.

         A copy of the Rights Agreement, which includes as Exhibit B the form
of Rights  Certificate,  is  filed  as an  Exhibit  hereto.  A copy  of the
Rights Agreement is available free of charge from the Company. This summary
description of the Rights does not purport to be complete  and is  qualified in
its entirety by reference to the Rights Agreement.
