                                PROXY STATEMENT

                              GENERAL INFORMATION

     The Annual Meeting of Shareholders of Martin Marietta Materials, Inc., a
North Carolina corporation (the "Corporation"), will be held on Thursday, May 1,
1997, at the North Raleigh Hilton, 3415 Wake Forest Road, Raleigh, North
Carolina, for the purposes set forth in the accompanying Notice of Annual
Meeting of Shareholders ("Annual Meeting" or "Meeting"). This statement is
furnished in connection with the solicitation by the Board of Directors of the
Corporation of proxies to be used at such meeting and at any and all
adjournments of such meeting.

     The Corporation's Annual Report for the fiscal year ended December 31,
1996, including audited financial statements, is being mailed to shareholders
with this Proxy Statement.

     Whether or not you plan to attend the meeting, we urge you to date, sign
and return your proxy in the enclosed envelope. You may revoke your proxy at any
time prior to its exercise at the Annual Meeting (i) by filing with the
Corporation's Secretary an instrument revoking the proxy prior to the Meeting,
(ii) by timely delivery to the Corporation's Secretary, or at the Meeting, of a
subsequently dated and executed proxy, or (iii) if you attend the Meeting, by
voting your shares in person. Attendance at the Meeting will not in and of
itself constitute a revocation of a proxy.

     The principal office of the Corporation is at 2710 Wycliff Road, Raleigh,
North Carolina 27607. This Proxy Statement, the Proxy Card, and the Notice of
Meeting will be sent to shareholders of record commencing approximately March
26, 1997.

Voting Securities and Record Date

     Only shareholders of record at the close of business on March 14, 1997 are
entitled to notice of and to vote at the Annual Meeting. On March 14, 1997,
there were 46,079,604 shares outstanding of the Corporation's Common Stock, $.01
par value per share ("Common Stock" or "Stock"). Each share is entitled to one
vote.

     Votes cast by proxy or in person at the Annual Meeting will be tabulated by
an independent inspector of election appointed by the Corporation's Board of
Directors for the Meeting from First Union National Bank of North Carolina, the
Corporation's transfer agent. The inspector of election will determine whether a
quorum is present. For purposes of determining the presence of a quorum,
abstentions will be counted as shares that are present and entitled to vote. If
a broker indicates on the proxy that it does not have discretionary authority to
vote on a particular matter and specific instructions are not received from the
shareholder regarding that matter, those shares represented by the proxy will
not be considered as present and entitled to vote with respect to that matter.



                                       1
<PAGE>   6



     The election of Directors requires a plurality of the votes cast with a
quorum present. Approval of any other proposals presented at the meeting
requires the affirmative vote of a majority of the votes cast by proxy or in
person. Brokers holding shares for beneficial owners must vote those shares
according to the specific instructions they receive from the beneficial owners.
If specific instructions are not received, brokers may generally vote these
shares in their discretion. However, the New York Stock Exchange rules preclude
brokers from exercising their voting discretion on certain proposals. In such
cases, absent specific instructions from the beneficial owner, the broker may
not vote on those proposals. This results in what is known as a "broker
non-vote." Because the Corporation's Bylaws require the affirmative vote of
either a plurality or majority of the votes cast at the Meeting to authorize
action on any matter (as described above), abstentions and broker non-votes,
which will not be counted "for" or "against" proposals, have no effect on the
vote for the election of Directors or approval of any of the other proposals.

     Each participant in the Corporation's Performance Sharing Plan and Savings
and Investment Plan may direct the trustee as to the manner in which shares of
Common Stock allocated to the plan participant's account are to be voted. If the
plan participant does not return a voting instruction card to the trustee in a
timely manner or returns a card without indicating any voting instructions, the
trustee will vote the shares in the same proportion as shares for which the
trustee receives voting instructions for that plan.

     In October 1996, the Corporation's Common Stock that was held by Lockheed
Martin Corporation became available to the public market when Lockheed Martin
disposed of its 81% ownership interest (the "Split-Off"). Before the effective
date of the Split-Off, Lockheed Martin Corporation and Martin Marietta
Investments Inc. held voting power over shares of Common Stock that represented
approximately 72.2% and 8.8%, respectively, of the shares entitled to be cast
for the election of the Board of Directors and approval of other proposals.
Martin Marietta Investments Inc. is a wholly-owned subsidiary of Lockheed Martin
Corporation, which is a Maryland corporation that was formed as the parent
corporation of Martin Marietta Corporation and Lockheed Corporation as a result
of the business combination of those two companies in March 1995. Martin
Marietta Corporation and Lockheed Corporation were subsequently merged into
Lockheed Martin Corporation in January 1996. Lockheed Martin Corporation is the
successor to Martin Marietta Technologies, Inc., which formerly held
approximately 72.2% of the Corporation's Common Stock. Unless otherwise
indicated, "Lockheed Martin Corporation" is used herein to refer to Martin
Marietta Corporation and its subsidiaries (other than the Corporation) prior to
its merger into Lockheed Martin Corporation in January 1996 and to Lockheed
Martin Corporation.

                             ELECTION OF DIRECTORS

     At the Special Meeting of Shareholders of the Corporation held on September
27, 1996 (the "Special Meeting"), the shareholders approved a proposal amending
the Corporation's Articles of Incorporation to provide for, among other things,
a classified board of directors such that the Board of Directors is divided into
three classes, each of which serves for three years. The Board of Directors has
nominated three persons for election as Directors to serve three-year terms
expiring in 2000. Unless otherwise directed, proxies will be voted in favor of
these three



                                       2

nominees. Each nominee has agreed to serve if elected. Each of the nominees is
currently serving as a Director. Should any nominee become unable to serve as a
Director, the persons named in the enclosed form of proxy will, unless otherwise
directed, vote for the election of such other person for such position as the
present Board of Directors may recommend in place of such nominee.

     The following sets forth certain biographical information, current
occupation and business experience for the past five years for each of the

                               BOARD OF DIRECTORS

     The Corporation's Board of Directors held eight meetings during 1996, of
which five were regularly scheduled meetings. In addition, management confers
frequently with its Directors on an informal basis to discuss Corporation
affairs. Other than Directors who are also officers of the Corporation or, prior
to the Split-Off, any affiliate of the Corporation (including officers of
Lockheed Martin Corporation), Directors serving in 1996 received a retainer of
$17,000 on an annualized basis until August 1996, and thereafter, $19,000 on an
annualized basis. Directors also received $1,000 for each regular or special
meeting of the Board and $500 for each Board committee meeting attended, in
addition to reimbursement for travel and other expenses related to attendance at
Board and committee meetings. Beginning in January 1997, Directors receive an
annual retainer of $25,000 and each committee chairman (other than the chairman
of the Executive Committee) also receives an annual fee of $1,000. Prior to the
Split-Off, Directors who were also officers of Lockheed Martin Corporation did
not receive any retainer or reimbursement of expenses from the Corporation in
connection with their attendance at meetings of the Board or its committees.

     Pursuant to the Amended and Restated Martin Marietta Materials, Inc. Common
Stock Purchase Plan for Directors, approved by the shareholders at the Special
Meeting, Directors may receive their compensation in either cash or, if
deferred, Common Stock, and may defer all or a portion of their fees until the
date the person ceases to be a Director or the date that is one month and one
year following the date the person ceases to be a Director. The Board of
Directors unanimously agreed that a minimum of 30% of each Director's annual
retainer would be paid in Common Stock and deferred under the plan.

     The Corporation's Board of Directors has five standing committees: an Audit
Committee, a Compensation Committee, an Ethics, Environment, Safety and Health
Committee, an Executive Committee and a Finance Committee. Prior to November
1996, the Corporation also had an Equity-Related Awards Committee.

     The Audit Committee, which is composed of Directors who are not officers or
employees of the Corporation, held four meetings during 1996. The Audit
Committee possesses and may exercise the powers of the Board of Directors,
except when such powers are by statute or the Articles of Incorporation or
Bylaws reserved to the full Board, relating to all accounting and auditing
matters of the Corporation. The Audit Committee recommends to the Board of
Directors the selection of the independent auditors. The Committee also monitors
the independence of the independent auditors. The Committee reviews the scope
and timing of work to be performed by the independent auditors; compensation to
be paid to the independent auditors; financial accounting and reporting
principles used by the Corporation; policies and procedures concerning audits,
accounting and financial controls; recommendations to improve existing
practices; and results of the audit and the report of the independent auditors.
The Committee also reviews the qualifications and the plan and scope of work of
the corporate

internal audit function. The Committee's current members are Directors Reed
(Chairman), Adamson, McDonald and Menaker.

     The Compensation Committee is composed of Directors who are not officers or
employees of the Corporation and who are also "disinterested" and "outside"
Directors as those terms are defined by the Securities and Exchange Act of 1934
and the Internal Revenue Code of 1986. It held five meetings during 1996. The
Committee has the power to fix the compensation to be paid for all elected
officers and employees. The Committee also approves and administers the grants
of stock options and any other awards that may be granted under the Martin
Marietta Materials, Inc. Amended Omnibus Securities Award Plan. The Committee
also has the power to administer any other compensation plan in connection with
which the Corporation or any of its employees may realize a benefit from
administration by disinterested Directors. The Committee's current members are
Directors Leonard (Chairman), Bennett, McDonald and Sansom.

     The Equity-Related Awards Committee held three meetings during 1996. The
Committee was composed of Directors who were not employees or officers of the
Corporation, and were also "disinterested" and "outside" Directors as those
terms are defined by the Securities Act of 1934 and the Internal Revenue Code of
1986. The Committee approved and administered the grants of awards under the
Corporation's Amended Omnibus Securities Award Plan, until November 1996, when
the Committee was dissolved by the Board of Directors and its former
responsibilities delegated to the Compensation Committee. The Committee's
members were Directors Sansom (Chairman), Leonard and Reed.

     The Ethics, Environment, Safety and Health Committee held four meetings
during 1996. It monitors compliance with the Martin Marietta Materials, Inc.
Code of Ethics and Standards of Conduct and reviews all matters presented to it
by the Corporate Ethics Officer concerning the ethical practices of the
Corporation and its employees, including conflicts or potential conflicts of
interest between the Corporation and any of its employees. The Committee also
reviews and monitors the adequacy of the Corporation's policies and procedures
and organizational structure for ensuring compliance with environmental laws and
regulations, and matters relating to health and safety. The Committee's current
members are Directors Sansom (Chairman), Adamson, Menaker and Vinroot.

     The Executive Committee held one meeting during 1996. It has the authority
to act during the intervals between the meetings of the Board of Directors and
may exercise the powers of the Board in the management of the business and
affairs of the Corporation as may be authorized by the Board of Directors. The
Committee's current members are Directors Bennett (Chairman), Reed and Zelnak.

     The Finance Committee held five meetings during 1996. It has been delegated
general oversight powers related to the management of the financial affairs of
the Corporation, including but not limited to, establishing lines of credit or
other short-term borrowing arrangements and investing excess working capital
funds on a short-term basis. The Committee reviews and makes recommendations to
the Board of Directors concerning changes to capital structure, including the



                                       7
<PAGE>   12


incurrence of long-term debt and issuance of equity securities, capital
expenditures and the contributions budget and the payment of dividends. The
Committee's current members are Directors Bennett (Chairman), Leonard, Reed and
Zelnak.

     The Bylaws of the Corporation require advance notice for any proposal for
the nomination for election as a Director at an annual meeting of shareholders
that is not included in the Corporation's notice of meeting or made by or at the
direction of the Board of Directors. In general, nominations must be delivered
to the Secretary of the Corporation at its principal executive offices, 2710
Wycliff Road, Raleigh, North Carolina 27607, not less than 60 days nor more than
90 days prior to the first anniversary of the preceding year's annual meeting
and must contain specified information concerning the nominee and the
shareholder proposing the nomination. Any shareholder desiring a copy of the
Bylaws of the Corporation will be furnished a copy without charge upon written
request to the Secretary of the Corporation.

     The following tables show annual and long-term compensation received from
the Corporation and Lockheed Martin Corporation for services in all capacities
to the Corporation (and prior to its incorporation, to Martin Marietta
Corporation), of the Chief Executive Officer and the next four most highly
compensated executive officers for the years ended December 31, 1996, 1995 and
1994. Other than compensation paid by the Corporation or Lockheed Martin
Corporation as set forth below, no annual or long-term compensation of any kind
was paid to the Chief Executive Officer or other named executive officers of the
Corporation in each of the years in the three-year period ended December 31,
1996. The information set forth in the table captioned "Option Grants in Last
Fiscal Year" relates to stock options with respect to the Common Stock of the
Corporation. The information set forth in the table captioned "Aggregated
Option/SAR Exercises in Last Fiscal Year and Fiscal Year-End Option/SAR Values"
relates to stock options and stock appreciation rights ("SARs") under plans
sponsored by the Corporation or by Lockheed Martin Corporation. Each stock
option and SAR outstanding under Martin Marietta Corporation stock option plans
at the time of the business combination between Martin Marietta Corporation and
Lockheed Corporation (effective as of March 1995), were fully vested (pursuant
to the change-in-control provisions in the plans) and converted into an option
and SAR with respect to the common stock of Lockheed Martin Corporation
(pursuant to an agreement entered into in connection with the combination).
Accordingly, securities granted under these plans are options exercisable for
the common stock of Lockheed Martin Corporation and in connection with the
Split-Off, terminate if not exercised before October 1997.

(1)  Bonuses were paid pursuant to the Martin Marietta Materials, Inc. Executive
     Incentive Plan. A portion of the cash bonus in 1996 and 1995 paid to the
     named executive officers and certain other key employees of the Corporation
     was deferred pursuant to the Martin Marietta Materials, Inc. Incentive
     Stock Plan. The amounts deferred in 1996 for each of the named executive
     officers are as follows: Mr. Zelnak, $170,000; Mr. Sipling, $54,100; Mr.
     Winchester, $26,550; Ms. Henry, $43,900; and Mr. Deerson, $29,100. The

     follows: Mr. Zelnak, $122,500; Mr. Sipling, $17,500; Mr. Winchester,
     $9,910; Ms. Henry, $15,440; and Mr. Deerson, $30,100. The amounts reported
     under "Bonus" do not include such deferred portion which are reported under
     "Other Annual Compensation."
(2)  The amounts reported under "Other Annual Compensation" represent the value
     of units that correspond to Common Stock credited to participants under the
     Martin Marietta Materials, Inc. Incentive Stock Plan (the "Plan"). Pursuant
     to the Plan, each participant at his or her election is permitted to use up
     to 50% of the annual incentive bonus earned by the participant to be
     credited towards units ("Units") that will subsequently be converted into
     Common Stock of the Corporation pursuant to the terms of the Plan at a 20%
     discount from the fair market value of the Common Stock (the closing price
     of the Common Stock as reported in the Wall Street Journal) on the date the
     amount of the bonus is determined. Each of the executive officers named are
     required to use a minimum of 10% of the annual incentive bonus towards the
     crediting of Units under the Plan, except for Mr. Zelnak, who is required
     to use a minimum of 25% towards the crediting of such Units. Any election
     to purchase Units under the Plan (in addition to the mandatory purchases)
     must be made at least six months prior to the date the amount of the annual
     incentive bonus is determined. The Units credited under the Plan generally
     vest at the end of the fiscal year in the year that is immediately
     preceding three years from the date of grant, at which time shares of
     Common Stock are issued to the participant. Dividend equivalents are paid
     on the Units at the same rate as dividends are paid to all shareholders.
     Such payments are included in the amounts reported. The amounts reported
     under "Other Annual Compensation" represent the market value on the date of
     grant of the Units credited to each named executive officer. The number of
     Units credited in 1996 to each of the named executives is as follows: Mr.
     Zelnak, 8,293; Mr. Sipling, 2,640; Mr. Winchester, 1,296; Ms. Henry, 2,142;
     and Mr. Deerson, 1,420. The number of Units credited in 1995 to each of the
     named executives is as follows: Mr. Zelnak, 7,292; Mr. Sipling, 1,191; Mr.
     Winchester, 590; Ms. Henry, 920; and Mr. Deerson 1,792.
(3)  Options granted are for Common Stock of the Corporation.
(4)  Amounts reported under this column represent payouts of awards under the
     Amended and Restated Martin Marietta Corporation Long Term Performance
     Incentive Compensation Plan. Upon consummation of the business combination
     of Martin Marietta Corporation and Lockheed Corporation, the plan was
     terminated as an active plan and no further awards will be made.
(5)  Amounts reported under "All Other Compensation" represent matching
     contributions to the Lockheed Martin Corporation Performance Sharing Plan
     and the Corporation's Performance Sharing Plan, and in 1995, for Mr.
     Zelnak, amounts paid under the Martin Marietta Corporation Deferred
     Compensation and Estate Supplement Plan. Amounts reported in 1995 also
     represent awards granted in 1993 under the Amended and Restated Martin
     Marietta Corporation Long Term Performance Incentive Compensation Plan,
     payment of which was accelerated upon the business combination of Martin
     Marietta Corporation and Lockheed Corporation. Accelerated payments were in
     the amounts that follow: Mr. Zelnak, $512,050; Mr. Sipling, $131,670; Mr.
     Winchester, $124,355; Ms. Henry, $146,300; and Mr. Deerson, $73,150.

(1)  Awards are granted at the discretion of a disinterested committee (the
     "Committee") of the Board of Directors of the Corporation upon the
     recommendation of management of the Corporation, except for Mr. Zelnak, for
     whom the Committee formulates its own decision, and may be awarded based on
     past performance or as incentive for future efforts. A maximum of 2,000,000
     shares of the Corporation's stock are authorized for grants to key
     employees. Each award under the Omnibus Plan is evidenced by an award
     agreement setting forth the number and type of stock-based incentives
     subject to the award and such other terms and conditions applicable to the
     award as determined by the Committee. Under the award agreement, options
     vest and become exercisable in three approximately equal increments on the
     first, second and third anniversary dates of the grant and expire 10 years
     from the date of grant. No individual may receive annual grants for more
     than 10 percent of the shares available under the Omnibus Plan. Options
     awarded in 1996 expire ninety days following termination of employment,
     except in instances following death, disability or retirement. In the event
     of death, all outstanding options vest immediately and will expire one year
     following the date of death. In instances of disability or normal
     retirement, the award agreement states that the terms of all outstanding
     options will be unaffected by such retirement or disability. In the event
     of early retirement, options that are not vested will terminate on the
     second business day after such retirement and options that are vested will
     terminate 90 days thereafter unless the Committee determines that all
     outstanding options will be unaffected by such retirement. The exercise
     price of the shares of Common Stock subject to options is set by the
     Committee and must be at least 100% of the fair market value of the shares
     on the date the option is granted. The award agreement provides that shares
     to be issued upon exercise of options may be purchased by the Company in
     the open market.
(2)  The dollar amounts set forth in these columns are the result of
     calculations at the 5 percent and 10 percent rates set by the Securities

Performance Sharing Plan

     The Martin Marietta Materials, Inc. Performance Sharing Plan (the
"Performance Sharing Plan"), which is sponsored by the Corporation, permits
eligible employees of the Corporation to make regular savings contributions on a
pre-tax or after-tax basis through systematic payroll deductions. For the year
ended December 31, 1996, participants could contribute up to 17 percent of their
current base salary subject to the limitations imposed by the Internal Revenue
Code, and direct the investment of such contributions into a Short-Term
Investment Fund, an Indexed Equity Fund, a fund which consists of the
Corporation's Common Stock, two Bond Funds, and five publicly traded mutual
funds. In addition, the Corporation makes monthly matching contributions to the
participant's account equal to 50 percent of up to the first 7 percent of the
compensation contributed by the participant. Plan contributions are 100 percent
vested.

     Prior to the Split-Off, eligible employees of the Corporation were entitled
to participate in the Martin Marietta Corporation Performance Sharing Plan,
which was substantially similar to the Corporation's Performance Sharing Plan
except that participants could choose to invest in a Lockheed Martin common
stock fund instead of a fund that consists of the Corporation's Common Stock. In
connection with the Split-Off, participants in the Martin Marietta Corporation
Performance Sharing Plan who had balances in the Lockheed Martin Corporation
common stock fund had the opportunity to exchange such shares for Common Stock
of the Corporation held in the Corporation's Performance Sharing Plan in
accordance with the Lockheed Martin Corporation Offer to Exchange pursuant to
the Offering Circular-Prospectus dated September 16, 1996, to otherwise transfer
the balance into other investment options in the Performance Sharing Plan or to
leave the balance in the Lockheed Martin Corporation common stock fund. Any
remaining balances in the Lockheed Martin Corporation common stock fund can be
withdrawn or transferred by the participant in accordance with the terms of the
Performance Sharing Plan for a period of 24 months following the Split-Off.
Thereafter, any remaining balances will automatically be reallocated to the
Short-Term Investment Fund in the Corporation's Performance Sharing Plan.

     Full distributions under the Performance Sharing Plan are generally made
upon the termination, layoff, retirement, disability or death of the
participant. Distributions of account balances invested in the Corporation's
Common Stock or in Lockheed Martin Corporation common stock are automatically
distributed in kind unless a recipient requests otherwise.

Pension Plans

     Prior to the Split-Off, the named executives participated in the Martin
Marietta Corporation Pension Plan for Salaried Employees (the "Pension Plan"),
which was sponsored by Lockheed Martin Corporation and covered all of the
Corporation's executive officers and substantially all of the salaried employees
of the Corporation on a non-contributing basis. In connection with the
Split-Off, the Pension Plan name was changed to the Martin Marietta Materials,
Inc. Pension Plan for Salaried Employees, and the plan sponsor changed to the
Corporation. Set forth below is a pension plan table which shows the estimated
annual benefits

(a)  Calculated under the Post-ERISA Formula.

(b)  The benefits payable under the Pension Plan may be limited by sections
     401(a)(17) and 415 of the Internal Revenue Code. The maximum earnings
     amount which may be considered to compute a benefit in accordance with
     Section 401(a)(17) of the Code is $150,000. The maximum annual amount
     payable under the Plan as of December 31, 1996 in accordance with Section
     415(b) of the Code is $120,000.

     Compensation covered by the Pension Plan generally includes, but is not
limited to, base salary, executive incentive compensation awards including the
deferred portion thereof, lump sum payments in lieu of a salary increase, and
overtime. The normal retirement age under the Pension Plan is 65, but unreduced
early retirement benefits are available at age 62 and reduced benefits are
available as early as age 55. The calculation of benefits under the Pension Plan
is generally based on an annual accrual rate, average compensation for the
highest consecutive five years of the ten years preceding retirement and the
participant's number of years of credited service. Maximum benefits payable
under the Pension Plan are subject to current Internal Revenue Code limitations.
The amounts listed in the foregoing table are not subject to any deduction for
Social Security benefits or other offsets amounts.

     Employees who participated prior to October 1, 1975 in a pension plan
covering employees of Martin Marietta Corporation's aerospace businesses are
eligible for an alternative pension formula (the "Pre-ERISA Formula").
Commencing in 1991, if a highly compensated employee eligible for the Pre-ERISA
Formula would receive a higher benefit under the Pre-ERISA Formula than under
the formula applicable to other employees (the "Post-ERISA Formula"), the
portion of the difference earned in 1991 and thereafter will be paid out of
general corporate assets. One executive officer of the Corporation was eligible
for the Pre-ERISA Formula during 1996.

     As of December 31, 1996, the estimated total annual benefits payable upon
retirement at age 65 for the individuals named in the compensation table, based
on continued employment at current compensation, are as follows: Mr. Zelnak,
$218,994; Mr. Sipling, $108,099; Mr. Winchester, $126,939; Ms. Henry, $146,279;
and Mr. Deerson, $104,709. These amounts include benefits that would have been
payable under Lockheed Martin Corporation's Supplemental Excess Retirement Plan.
The years of credited service upon assumed retirement at age 65 for Mr. Zelnak,
Mr. Sipling, Mr. Winchester, Ms. Henry, and Mr. Deerson are 28.75 years, 27.67
years, 31.08 years, 41.67 years, and 36.75 years, respectively.



                                       16



<PAGE>   21

     Sections 401(a) (17) and 415 of the Internal Revenue Code limit the annual
benefits payable under the Pension Plan. As permitted by ERISA, Lockheed Martin
Corporation maintained the Supplemental Excess Retirement Plan, which provides
for the payment of benefits in excess of those limits and payment of amounts
equalizing the differences in the accrual method for those certain employees who
were not participants in the Pension Plan prior to October 1, 1975.

Employment Protection Agreements

     The Corporation has entered into Employment Protection Agreements (the
"Agreements") with each of the named executive officers. The purpose of these
Agreements is to provide the Corporation's key executives with payments and
benefits upon certain types of terminations within two years and 30 days
following a "Change of Control." For purposes of the Agreements, a Change of
Control is generally defined as (i) the acquisition by any person, or related
group of persons, of 40% or more of either the outstanding Common Stock of the
Corporation or the combined voting power of the Corporation's outstanding
securities, (ii) consummation of a reorganization, merger or consolidation or
sale or other disposition of all or substantially all of the Corporation's
assets following which the Corporation's shareholders before such event fail to
own more than 40% of the resulting entity, (iii) a change in the majority
membership of the Board, (iv) a liquidation or dissolution of the
Corporation, or (v) a sale of all or substantially all of the Corporation's
assets.

     The Agreements provide that if, within the two year period following a
Change of Control, an executive is terminated without "Cause" (as defined in the
Agreements) or terminates his employment with "Good Reason" (as defined in the
Agreements), or if the executive voluntarily terminates his employment for any
reason during the thirty-day period following the second anniversary of the
Change of Control, the Corporation is obligated to pay the executive, in a lump
sum, an amount equal to twice the sum of the executive's "Base Salary" and
"Annual Bonus." For purposes of the Agreements, Base Salary means the highest
annual rate of base salary that the executive received within the twelve-month
period ending on the date of the Change of Control and Annual Bonus means the
executive's highest annual bonus paid during the period beginning five years
prior to the Change of Control and ending on the date of the executive's
termination of employment. In addition, for two years following termination of
employment, the Corporation must provide the executive with welfare benefits
that are generally as favorable as those the executive enjoyed prior to the
Change of Control. Furthermore, the Agreements provide for "gross-up" payments
to compensate the executives for any golden parachute excise taxes imposed under
the Internal Revenue Code on account of the severance amounts.

     The term of the Agreements is three years following their effective dates.
On each anniversary date of the effective date, the Agreements are renewed for
one additional year, unless either party gives notice of its intent to cancel
the automatic extension.

                      REPORT OF THE COMPENSATION COMMITTEE
                            ON EXECUTIVE COMPENSATION

     The Corporation's executive compensation program is administered by the
Compensation Committee (the "Committee") of the Board of Directors and, prior to
November 1996, the Equity-Related Awards Committee. The role of the Compensation
Committee is to approve salaries and other compensation of the executive
officers of the Corporation. The role of the Equity-Related Awards Committee,
which was redelegated by the Board of Directors to the Compensation Committee in
November 1996, was to review, approve and administer grants of stock options and
equity-related awards to all employees, including the principal officers of the
Corporation, and to administer any other compensation plan in connection with
which the Corporation or any of its employees may realize a benefit from
administration by disinterested Directors. The Equity-Related Awards Committee
was dissolved in November 1996.

General Compensation Policies and Practices

     The Committee supports the Corporation's belief that executive compensation
should further the Corporation's strategic goals. To accomplish this, the
Committee's policy with respect to executive compensation holds that the
Corporation's employees are its most important resource and should be
compensated fairly in order to achieve optimum operating performance for the
Corporation. The Committee focuses on operating performance rather than
short-term changes in stock price based on its view that the long-term operating
performance of the Corporation will be reflected by stock price performance over
the long-term. Competitive compensation levels serve to attract and retain
individuals of outstanding ability and motivate such individuals to sustain high
levels of personal performance. The type and amount of compensation granted is
based upon the subjective judgment of the Committee; nevertheless, in the
exercise of its discretion, the Committee considers a number of objective
criteria which are discussed below in the context of the components of
compensation to which they apply.

Compensation Structure and Awards for 1996

     The key elements of the Corporation's compensation structure are:

- -    Annual Compensation - consisting of base salary and bonus (incentive
     compensation).

- -    Long-Term Compensation - consisting of stock options and incentive stock
     awards.

     Annual Compensation - Base Salary. In setting base salaries for 1996, the
Committee reviewed surveys conducted by an outside compensation consulting firm
of a selected peer group of companies in the aggregates, cement and specialty
chemical industries, including those in the Performance Graph peer group on page
22, and of a selected group of general industry companies with comparable
revenues to those of the Corporation. The Committee also reviewed national
surveys of compensation levels for executives employed in similar positions in
general industry companies with revenues similar to that of the Corporation. The
group of companies 



                                       18



<PAGE>   23

reflected in the compensation surveys was broader than the group of peer
companies set forth in the Performance Graph on page 22. The Committee also
considered the advice of independent compensation advisors.

     Salaries for executives are reviewed by the Compensation Committee on an
annual basis and may be increased at that time based on: (1) the Committee's
agreement on the individual's contribution to the Corporation, and (2) increases
in median competitive pay levels. The total cash compensation (base salary and
bonus described below) for each of the named executive officers was below the
median compensation of executives having similar responsibilities in the
compensation surveys, including those in the Performance Graph peer group.

     The base salary for the Vice Chairman, President and Chief Executive
Officer of the Corporation was increased during 1996 to $420,000. This
represents an approximate 20 percent increase from 1995. The rate of increase in
1996 reflected the Committee's unanimous agreement on Mr. Zelnak's continued
superior leadership ability as demonstrated by the Corporation's excellent
financial performance as to record sales and earnings. Under Mr. Zelnak's
guidance, the Corporation achieved strong earnings growth and remained an
industry leader in performance as measured by return on sales and return on
investment. In addition, the Committee also reviewed base salary data for chief
executive officers in the compensation studies and in the Performance Graph peer
group.

     Annual Compensation - Bonus. To encourage achievement of the performance
objectives of the Corporation, a significant portion of annual compensation
takes the form of an incentive compensation bonus. In 1996, under the
Corporation's Executive Incentive Plan, the maximum amount that an executive
could receive was based upon a percentage of that executive's base salary. All
of the executive officers participate in the plan, except for Mr. Zelnak, for
whom bonus consideration is made outside the plan.

     Following review of the achievements of the Corporation as compared to the
targeted goals set at the end of the previous year, a comparative review of each
of the individual contributions of all participants towards achieving these
goals is conducted. The Compensation Committee also considers qualitative
measures of performance such as adherence to and implementation of the
Corporation's policy on ethics and standards of conduct, customer satisfaction
and product quality.

     The amount actually awarded to each participant in the plan is based upon
the Compensation Committee's assessment of each individual's achievement of
targeted objectives, including standard measures of financial performance such
as sales, earnings, return on capital investments and cash generation. These
objectives are established at the beginning of each plan year and are based upon
the Corporation's Long Range Operating Plan. For executives in corporate staff
positions, 50 percent of the determination is made with respect to the
Corporation's performance and 50 percent is based on the individual's
performance. The Committee considers the recommendations of the Corporation's
Chief Executive Officer but retains complete discretion in performing these
reviews.



                                       19


<PAGE>   24

     Mr. Zelnak was awarded an annual incentive bonus of $340,000 for 1996 based
on Mr. Zelnak's outstanding performance and leadership in connection with the
Corporation's financial achievements and the Split-Off. The Corporation's
Incentive Stock Plan requires Mr. Zelnak to use 25% of his 1996 annual incentive
bonus towards credits of Common Stock units at a 20% discount to market value,
which generally vest in three years. In addition, Mr. Zelnak made an irrevocable
choice six months prior to the bonus determination to use 25% more, for a total
of 50% of his annual incentive bonus, towards Common Stock units. Although there
was no special attempt to set Mr. Zelnak's 1996 bonus in any particular
relationship to the compensation data, Mr. Zelnak's bonus was at the median
level of bonus compensation of CEO's in the compensation surveys, including
those in the Performance Graph peer group. His total cash compensation (base
salary and bonus) was below the median compensation of those CEOs. The
Compensation Committee retains complete discretion in determining the amount of
incentive compensation to be awarded to Mr. Zelnak. Consequently, no particular
weighting of criteria is required or performed.

     Long Term Compensation - Stock Options. Stock options awarded under the
Corporation's Amended Omnibus Securities Award Plan link the compensation
provided to a group of 75 executive officers and key personnel with gains
realized by the shareholders. The vesting periods associated with stock options
encourage continued employment with the Corporation while also serving to confer
on recipients an ownership interest in the Corporation.

     The number of options granted to an individual is based upon survey data
provided by compensation consultants. The data shows the value of option awards
as a multiple of base pay for comparable executive positions in other
corporations. In making 1996 stock option award decisions, the Committee elected
to provide option awards, as a multiple of base salary, near the average for
awards made by firms in a national compensation group comprised of the same
companies surveyed in the Compensation Committee's review of base salaries. The
determination of the number of options awarded is in the complete discretion of
the Committee, which considers the recommendations of the Chief Executive
Officer with respect to participants other than the Chief Executive Officer, and
which formulates its own decision with respect to the Chief Executive Officer.
The Committee awarded Mr. Zelnak 47,000 options in 1996 to align more directly
Mr. Zelnak's compensation with the Corporation's performance. In exercising its
discretion, the Committee generally follows the same procedures as are followed
in determining the amount of incentive compensation awards discussed above.

     Since long-term awards vest over time, the Committee grants new awards to
provide continuing incentives for future performance without regard to the
number of options currently held by the recipient. Options awarded are not
transferable and have an exercise price equal to the closing price of the
Corporation's Common Stock on the date of grant, and therefore, have no value to
the recipient unless the price of the Common Stock increases.

     Long Term Compensation - Incentive Stock Awards. In 1996, a group of 25
executive officers and key personnel was granted awards under the Martin
Marietta Materials, Inc. Incentive Stock Plan. The plan is intended to give key
employees who participate in the Executive Incentive Plan the opportunity to
invest up to 50% of their annual incentive awards to 


                                       20


<PAGE>   25

purchase units that are subsequently converted into shares of Common Stock
pursuant to the terms of the plan at a 20% discount from the market price of the
Corporation's Common Stock on the date of the award. The units become fully
vested and are distributed in the form of unrestricted Common Stock after three
years of continued additional employment with the Corporation. Participation in
the plan is elective, except that executive officers of the Corporation are
required to invest a minimum percentage of their annual incentive awards in
units that are subsequently converted into the Corporation's Common Stock in
accordance with the terms of the Incentive Stock Plan. The plan is intended to
assist the Corporation in attracting and retaining key employees, to link
directly executive officer and management compensation to shareholder returns,
and to foster stock ownership in the Corporation among its key employees.

     The value, if any, of stock-based awards is dependent upon the performance
of the Corporation's Common Stock. Further, as noted above, in exercising its
discretion in determining the type and amount of award made, the Committee
considers many factors related to the Corporation's performance and the
performance of the individual being considered for an award. While objective
criteria are carefully considered, the Committee has the discretion to make
awards as it deems appropriate. Therefore, there is no formula that results in a
direct or quantifiable correlation between performance and stock-related awards.


Policy with Respect to Deductibility of Compensation

     The Corporation has not awarded any compensation that is non-deductible
under Section 162(m) of the Internal Revenue Code. In the event that the
Committee considers awarding compensation in the future that would not be
deductible under Section 162(m), the Committee may, if it deems it appropriate,
consider taking actions to seek to make such compensation deductible.

     Messrs. Bennett, Leonard, McDonald and Sansom served on the Corporation's
Compensation Committee during 1996. Mr. Bennett is Executive Vice President,
Chief Financial Officer and a Director of Lockheed Martin Corporation which,
until the Split-Off, owned approximately 81% of the Corporation's Common Stock.
He is not, and was not, an officer or employee of the Corporation or any of its
subsidiaries. Information with respect to transactions between the Corporation
and Lockheed Martin Corporation can be found in "Certain Related Transactions"
below.

                          CERTAIN RELATED TRANSACTIONS

     The following transactions involve amounts exceeding $60,000 in which
certain shareholders or Directors of the Corporation may have a material
interest.

Transactions with Lockheed Martin Corporation

     Before the Split-Off, Lockheed Martin Corporation (which was formed as a
result of the business combination of Martin Marietta Corporation and Lockheed
Corporation) owned directly and through its wholly owned subsidiary Martin
Marietta Investments Inc. approximately 81% of the Corporation's outstanding
Common Stock. The Corporation's relationship with Lockheed Martin Corporation
was governed by agreements, as amended from time to time, entered into in
connection with the incorporation of the Corporation in November 1993 and the
initial public offering of a portion of the Corporation's Common Stock in
February 1994 (the "Offering"), including a credit agreement, a cash management
agreement, a services agreement, an assumption agreement and certain other
agreements. Because of Lockheed Martin Corporation's control of the Corporation,
and its Board of Directors, none of the agreements resulted from an arm's-length
negotiation.

     Credit Agreement

     Pursuant to an Amended and Restated Credit Agreement dated as of January 2,
1995, as amended from time to time (the "Credit Agreement") between the
Corporation and Lockheed Martin Corporation, Lockheed Martin Corporation agreed
to provide (i) term loans of up to $75 million and (ii) a revolving credit loan
of up to $25 million, each for general corporate purposes. In March 1996, the
Credit Agreement was amended to increase the revolving credit loan to provide
for up to $55 million. Under the term loan portion of the Credit Agreement,
Lockheed Martin Corporation's commitment to extend credit expired on June 30,
1995.

     There was no required prepayment or scheduled reduction of availability of
credit under the revolving credit loan. The Corporation and Lockheed Martin had
the right, upon 90 or 120 days notice, respectively, to reduce the unused
portion of the revolving credit loan. Depending on type and duration of
borrowing, interest payments were due monthly, quarterly or upon maturity of the
revolving credit loan.




                                       23


<PAGE>   28

     Subject to certain conditions, revolving credit loans outstanding under the
Credit Agreement in 1996 bore interest either at (i) the rate announced from
time to time by Morgan Guaranty Trust Company of New York as its prime rate, or
(ii) LIBOR plus a margin. The Credit Agreement provided that, as of March 1996,
loans borrowed at LIBOR carried a margin of .25 to .40 percent depending upon
the rating received by the Corporation from nationally recognized rating
agencies on the Corporation's unsecured senior long-term debt. Prior to March
1996, loans borrowed at LIBOR carried a margin of .375%.

     The Corporation was required to pay Lockheed Martin Corporation a
commitment fee equal to .125 percent per annum on the amount of the available
but unused borrowing commitment under the Credit Agreement.

     The revolving credit loan portion of the Credit Agreement terminated on
January 31, 1997.

     Cash Management Agreement

     The Corporation and Lockheed Martin Corporation entered into a cash
management agreement dated February 17, 1994 (the "Cash Management Agreement")
pursuant to which Lockheed Martin Corporation provided daily liquidity and
investment capability for the Corporation. The Cash Management Agreement had an
initial term of three years from the completion of the Offering, but was
terminable by either party after one year on 90 days' written notice. In
accordance with the terms of the Cash Management Agreement, excess cash balances
of the Corporation were advanced to Lockheed Martin Corporation on an overnight
basis, and earned interest at a rate per annum equal to the federal funds rate
as in effect from time to time. Cash shortfalls, up to $2 million, were funded
by Lockheed Martin Corporation on an overnight basis, and bore interest at a
rate per annum equal to the federal funds rate as in effect from time to time.
The cost to the Corporation for the services provided pursuant to the Cash
Management Agreement were included in the Services Agreement, discussed below.
No additional compensation was paid to Lockheed Martin Corporation for such
services. The Cash Management Agreement was terminated on January 31, 1997.

     Services Agreement

     Pursuant to an intercompany services agreement dated February 17, 1994 (the
"Services Agreement"), up until the time of the Split-Off, Lockheed Martin
Corporation furnished to the Corporation a package of services in exchange for a
service fee, which was determined by Lockheed Martin Corporation on a basis
consistent with past practices, recognizing, to the extent practicable, Lockheed
Martin Corporation's reduced ownership of the Corporation after the Offering,
the Corporation's requirements for certain services for which it was previously
charged by Lockheed Martin Corporation and the Corporation's costs of obtaining
services previously provided by Lockheed Martin Corporation. The cost to the
Corporation reflecting the service fee in 1996 was approximately $4.8 million.
In addition to the service fee, the Corporation agreed to reimburse Lockheed
Martin Corporation for certain identified costs.


                                       24


<PAGE>   29

     The services provided by Lockheed Martin Corporation included certain tax
services; control and internal audit services; insurance advice and purchasing;
health, safety and environmental management services; treasury and cash
management services; employee relations services; legal services; employee
benefit plan investment services; and services of Lockheed Martin Corporation's
Executive Department (including services of Executive Department staff members
in connection with their duties as Directors of the Corporation).

     In addition to the identified services, Lockheed Martin Corporation
continued coverage of the Corporation under Lockheed Martin Corporation's
policies for primary, general and automobile liability, excess liability,
property, fiduciary liability, directors' and officers' liability, marine,
blanket crime and workers' compensation insurance. The Corporation agreed to
reimburse Lockheed Martin Corporation for the portion of Lockheed Martin
Corporation's premium cost with respect to such insurance that was attributable
to coverage of the Corporation. Under the Services Agreement, Lockheed Martin
Corporation charged the Corporation a premium that approximated the actual cost
to Lockheed Martin Corporation of coverage of the Corporation.

     Also, in addition to the identified services, Lockheed Martin Corporation
allowed employees of the Corporation to participate in certain of the Lockheed
Martin Corporation employee benefit plans. In addition to the monthly fee, under
the services agreement, the Corporation agreed to reimburse Lockheed Martin
Corporation for certain of Lockheed Martin Corporation's costs (including any
contributions and premium costs and including certain third-party expenses and
allocation of certain Lockheed Martin Corporation personnel expense) relating to
participation by the Corporation's employees in Lockheed Martin Corporation's
benefit plans. In addition to contribution and premium costs, the Corporation
paid in 1996 approximately $.9 million to Lockheed Martin Corporation
representing an allocation for certain administrative services relating to
employee benefits.

     The Services Agreement was terminated at the time of the Split-Off. A
Transition Agreement dated as of October 18, 1996 was entered into by the
Corporation and Lockheed Martin Corporation that provides, among other things,
for certain services to be continued to be provided by Lockheed Martin
Corporation throughout 1997 and for the transfer from Lockheed Martin
Corporation to the Corporation of certain assets related to the Corporation's
business, including those in connection with the Corporation's defined benefit,
defined contribution and certain other benefit plans.

     Assumption Agreement

     In connection with its incorporation, the Corporation assumed, among other
things, all payment obligations of Martin Marietta Technologies, Inc. (including
principal, interest and premium, if any, and including all fees, costs and
expenses with respect to such obligations) with respect to certain $125 million
principal amount of 9 1/2% Notes of Martin Marietta Technologies, Inc. which
were defeased in-substance, $100 million principal amount of 8 1/2% Notes of
Martin 


                                       25



<PAGE>   30

Marietta Technologies, Inc., and certain other indebtedness incurred in
connection with prior acquisitions by Martin Marietta Corporation's materials
group. The 9 1/2% Notes were defeased with net proceeds from the Offering and
subsequently paid in full. Lockheed Martin Corporation agreed to pay to the
Corporation, within five business days after the due date of each semiannual
payment of interest by the Corporation in respect of the 8 1/2 Notes, $1.75
million to reimburse the Corporation for the portion of interest paid by the
Corporation in excess of the market rate of interest on the date of the
assumption (5% per annum). The 8 1/2 Notes were repaid by the Corporation when
they became due on March 1, 1996.

     The Tax Sharing, Supplemental Tax 
     Sharing and Tax Assurance Agreements

     The Corporation was included in Lockheed Martin Corporation's consolidated
tax group until and including the effective day of the Split-Off, and therefore
the taxable income (or loss) of the Corporation and its subsidiaries (the
"Materials Consolidated Group") was included in the Lockheed Martin Corporation
consolidated federal income tax return until such date. The Corporation and
Lockheed Martin Corporation, as successor to Martin Marietta Corporation, are
parties to a Tax Sharing Agreement, dated February 18, 1994, that allocates
responsibility between the Corporation and Lockheed Martin Corporation for their
respective shares of the consolidated federal income tax liability of Lockheed
Martin Corporation and certain other liabilities. Pursuant to the Tax Sharing
Agreement, the Corporation and Lockheed Martin Corporation make payments between
them such that, with respect to any period, the amount of taxes paid by the
Corporation or any refund payable to the Corporation is determined as though the
Corporation filed separate federal, state and local income tax returns
(including any amounts determined to be due as a result of a redetermination of
the tax liability of Lockheed Martin Corporation arising from an audit or
otherwise) as the common parent of an affiliated group of corporations filing a
consolidated return rather than a consolidated subsidiary of Lockheed Martin
Corporation.

     In anticipation of the Split-Off, the Corporation and Lockheed Martin
Corporation entered into a Supplemental Tax Sharing Agreement and a Tax
Assurance Agreement. The Supplemental Tax Sharing Agreement allocates
responsibility between the Corporation and Lockheed Martin Corporation for
certain tax liabilities (including any related liability of the Corporation or
Lockheed Martin Corporation to stockholders of Lockheed Martin Corporation) that
may result from the failure of the Split-Off to qualify as a fully tax-free
distribution. Pursuant to this agreement, any such liability generally will be
allocated 81% to Lockheed Martin Corporation and 19% to the Corporation, subject
to a maximum allocation of $25 million to the Corporation. However, if either
Lockheed Martin Corporation or the Corporation (but not both) knowingly or
willfully breaches a covenant contained in the Tax Assurance Agreement, which
contains covenants relating to the parties' post-Split-Off conduct which could
jeopardize the qualification of the Split-Off as fully tax-free (if, among other
things, there is a change of law or in the ruling policy of the IRS), and the
failure of the Split-Off to qualify as a fully tax-free distribution would not
have occurred but for such breach, the resulting liability will be allocated
solely to the breaching party. The Corporation would not be solely liable for
the resulting 


                                       26





<PAGE>   31

liability if it first obtained an opinion of counsel (satisfactory
to Lockheed Martin Corporation) to the effect that any action underlying a
breach would not cause the Split-Off to fail to qualify as a fully tax-free
distribution. Furthermore, if either Lockheed Martin Corporation or the
Corporation is acquired in a manner that causes the failure of the Split-Off to
qualify as a fully tax-free distribution under Section 355 of the Internal
Revenue Code (including the recognition of gain to Lockheed Martin Corporation
on the distribution of the Corporation's Common Stock pursuant to Section
355(d) of the Internal Revenue Code) and the gain did not result from a breach
of the Tax Assurance Agreement, the resulting liability will be allocated
solely to the corporation so acquired.

Other Transactions

     Mr. Vinroot is a partner with the law firm of Robinson, Bradshaw & Hinson,
P.A., which has provided certain legal services for the Corporation in an amount
less than 5% of such firm's gross revenues for the firm's last fiscal year.


                       SECTION 16(a) BENEFICIAL OWNERSHIP
                              REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act requires Directors and officers of the
Corporation and persons who own more than 10% of the Common Stock to file with
the Securities and Exchange Commission initial reports of ownership and reports
in changes in ownership of the Common Stock. Directors, officers and more than
10% shareholders are required by Securities and Exchange Commission regulations
to furnish to the Corporation copies of all Section 16(a) reports filed.

     Based solely on its review of the copies of reports furnished to the
Corporation and written representations that no other reports were required for
the year ended 1996, the Corporation is not aware of any reporting person who
failed to file on a timely basis all reports required by Section 16(a) to be
filed during 1996.

                              INDEPENDENT AUDITORS

     The Board of Directors recommends that the shareholders ratify the
appointment of Ernst & Young LLP, independent auditors, to audit the
consolidated financial statements of the Corporation for the fiscal year 1997.
The ratification of the appointment of Ernst & Young LLP is being submitted to
the shareholders because management believes this to be good corporate practice.
Should the shareholders fail to ratify this appointment, the Board of Directors
will review the matter. Representatives of Ernst & Young LLP are expected to
attend the Annual Meeting of Shareholders of the Corporation, will have the
opportunity to make a statement if they so desire, and will be available to
respond to appropriate questions from shareholders.

<PAGE>   32



                              FINANCIAL STATEMENTS

     Upon the written request of any shareholder, the Corporation will provide
without charge a copy of its Annual Report on Form 10-K for the year ended
December 31, 1996, filed with the Securities and Exchange Commission. Requests
should be mailed to the Corporate Secretary, Martin Marietta Materials, Inc.,
2710 Wycliff Road, Raleigh, North Carolina 27607.

                          METHOD OF PROXY SOLICITATION

     The entire cost of preparing, assembling, printing and mailing the Notice
of Meeting, this Proxy Statement and proxies and the cost of soliciting proxies
relating to the meeting, if any, has been or will be paid by the Corporation. In
addition to use of the mails, proxies may be solicited by officers, directors
and other regular employees of the Corporation by telephone, facsimile or
personal solicitation, and no additional compensation will be paid to such
individuals. The Corporation will use the services of Morrow & Co., Inc., a
professional soliciting organization, to assist in obtaining in person or by
proxy the largest number of shareholder vote as is possible. The Corporation
estimates its expenses for solicitation services will not exceed $12,500. The
Corporation will, if requested, reimburse banks, brokerage houses and other
custodians, nominees and certain fiduciaries for their reasonable expenses
incurred in mailing proxy materials to their principals.

                                 OTHER MATTERS

     At the time this Proxy Statement was filed with the Securities and Exchange
Commission, the Board of Directors was not aware that any matters not referred
to herein would be presented for action at the Annual Meeting. If any other
matters properly come before the Meeting, it is intended that the persons named
in the enclosed proxy will vote the shares represented by proxies on such
matters in accordance with their judgment in the best interest of the
Corporation. It is also intended that discretionary authority will be exercised
with respect to the vote on any matters incident to the conduct of the meeting.

     Proposals by shareholders intended to be presented at the 1998 Annual
Meeting of Shareholders of the Corporation must be received by the Secretary of
the Corporation no later than November 19, 1997 in order to be included in the
Proxy Statement and on the Proxy Card that will be solicited by the Board of
Directors in connection with that meeting. The inclusion of any proposal will be

specified information concerning the matter to be brought before such meeting
and concerning the shareholder proposing such a matter. Any waiver by the
Corporation of these requirements with respect to the submission of a particular
shareholder proposal shall not constitute a waiver with respect to the
submission of any other shareholder proposal nor shall it obligate the
Corporation to waive these requirements with respect to future submissions of
the shareholder proposal or any other shareholder proposal. Any shareholder
desiring a copy of the Bylaws of the Corporation will be furnished one without
charge upon written request to the Secretary of the Corporation at its principal
