Dear Fellow Stockholder:
 
You are cordially invited to attend a special meeting of stockholders of Martin
Marietta Corporation on March 15, 1995, at 9:00 a.m. at The Drake Hotel, 140 E.
Walton Place, Chicago, Illinois. At this meeting, you will be asked to approve
the combination of the businesses of Martin Marietta and Lockheed Corporation.
Subject to the receipt of the requisite approvals, Martin Marietta and Lockheed
will become subsidiaries of a new holding company named Lockheed Martin
Corporation.
 
Upon completion of this transaction:
 
     -  each outstanding share of Martin Marietta Common Stock will be converted
        into the right to receive one share of Lockheed Martin Common Stock;
 
     -  each outstanding share of Lockheed Common Stock will be converted into
        the right to receive 1.63 shares of Lockheed Martin Common Stock; and
 
     -  each outstanding share of Martin Marietta Series A Preferred Stock will
        be converted into the right to receive one share of Series A Preferred
        Stock of Lockheed Martin.
 
The accompanying Joint Proxy Statement/Prospectus provides you with detailed
information concerning the special meeting, the proposed combination and the
Lockheed Martin stock to be issued once this transaction has closed. Please give
all of this information your careful attention.
 
The Board of Directors has thoroughly reviewed the terms and conditions of the
proposed combination. The Board believes that the new company created by this
combination will be strategically positioned in the aerospace industry. The
Board also believes this transaction will broaden Martin Marietta's core
businesses, both defense and non-defense, by providing economies of scale. This
will enable Lockheed Martin to make its products and services more competitive
in an ever more challenging global marketplace. In addition, the Board believes
the combination is a proactive, responsible step in the continuing consolidation
in the U.S. aerospace industry.
 
Bear, Stearns & Co. Inc., the Board's financial advisor in connection with this
transaction, has rendered its written opinion, a copy of which is attached to
the Joint Proxy Statement/Prospectus. It states that the proposed combination is
fair, from a financial point of view, to the stockholders of Martin Marietta.
 
The Board, by unanimous vote, has determined that the terms of the combination
are in the best interests of the stockholders of Martin Marietta and recommends
that you vote FOR the proposal to approve the combination.
 
At the special meeting, holders of Martin Marietta Common Stock will also be
asked to consider and approve the adoption of an omnibus performance award plan
and a directors deferred stock plan for Lockheed Martin, the terms of which are
also described in the Joint Proxy Statement/Prospectus. Consummation of the
combination is not conditioned on approval of the omnibus performance award plan
or the directors deferred
<PAGE>   3
 
stock plan. The Board also unanimously recommends that holders of Martin
Marietta Common Stock vote FOR the proposals to approve these plans.
 
Your vote is important, and I respectfully urge all stockholders to complete,
sign and date the enclosed proxy card and return it in the enclosed prepaid
envelope as soon as possible. This action does not limit your right to revoke
your proxy by attending the special meeting and voting in person.
 
                                            Sincerely yours,

                                            /s/ NORMAN R. AUGUSTINE

                             JOINT PROXY STATEMENT
 
                      FOR SPECIAL MEETINGS OF STOCKHOLDERS
                           TO BE HELD MARCH 15, 1995
                            ------------------------
 
                          LOCKHEED MARTIN CORPORATION
 
                                   PROSPECTUS
 
     This Joint Proxy Statement/Prospectus is being furnished to holders of
common stock of Lockheed Corporation, a Delaware corporation ("Lockheed"), and
holders of common stock and preferred stock of Martin Marietta Corporation, a
Maryland corporation ("Martin Marietta"), in connection with the solicitation of
proxies by the respective Boards of Directors of Lockheed and Martin Marietta
for use at their respective special meetings of stockholders, or any adjournment
or postponement thereof (together, the "Special Meetings"), called to consider
and vote upon a proposal (the "Combination Proposal") to approve and adopt an
Agreement and Plan of Reorganization, dated as of August 29, 1994, by and among
Lockheed, Martin Marietta and Lockheed Martin Corporation, a Maryland
corporation ("Lockheed Martin"), as amended as of February 7, 1995 (the
"Reorganization Agreement"), and the merger agreements contemplated thereby. The
combination of the businesses of Lockheed and Martin Marietta contemplated by
the Combination Proposal is referred to herein as the "Combination." At the
Special Meetings, holders of common stock of Lockheed and Martin Marietta also
will be asked to consider and vote upon a separate proposal (the "Omnibus Plan
Proposal") to approve the adoption of the Lockheed Martin 1995 Omnibus
Performance Award Plan (the "Lockheed Martin Omnibus Plan") and another separate
proposal (the "Directors Plan Proposal" and, with the Omnibus Plan Proposal, the
"Plan Proposals") to approve the adoption of the Lockheed Martin Directors
Deferred Stock Plan (the "Lockheed Martin Directors Plan").
 
     The Reorganization Agreement provides, among other things, for (a) the
merger of Atlantic Sub, Inc., a Maryland corporation and wholly owned subsidiary
of Lockheed Martin ("Atlantic Sub"), with and into Martin Marietta (the
"Atlantic Sub Merger") pursuant to a Plan and Agreement of Merger, dated as of
August 29, 1994 (the "Atlantic Merger Agreement"), among Martin Marietta,
Atlantic Sub and Lockheed Martin, and (b) the merger of Pacific Sub, Inc., a
Delaware corporation and a wholly owned subsidiary of Lockheed Martin ("Pacific
Sub"), with and into Lockheed pursuant to a Plan and Agreement of Merger, dated
as of August 29, 1994 (the "Pacific Merger Agreement"), among Lockheed, Pacific
Sub and Lockheed Martin (the "Pacific Sub Merger" and together with the Atlantic
Sub Merger, the "Mergers"). As a result of the Combination, each of Lockheed and
Martin Marietta will become a wholly owned subsidiary of Lockheed Martin and
stockholders of Lockheed and Martin Marietta will become stockholders of
Lockheed Martin on the terms described in this Joint Proxy Statement/Prospectus.
The Combination will be accomplished pursuant to the Mergers. The Mergers will
become effective pursuant to the filing of Articles of Merger with the
Department of Assessments and Taxation of the State of Maryland and the filing
of a Certificate of Merger with the Secretary of State of the State of Delaware
(the date on which the Mergers are to become effective being herein referred to
as the "Merger Date"), which is currently expected to occur shortly after the
Special Meetings if the Combination Proposal is approved and adopted by the
requisite vote of the respective stockholders of Lockheed and Martin Marietta,
and after receipt of requisite regulatory approvals. See "THE COMBINATION" and
"THE REORGANIZATION AGREEMENT."
 
     Lockheed Martin has filed a registration statement on Form S-4 (together
with all amendments, exhibits and schedules thereto, the "Registration
Statement") under the Securities Act of 1933, as amended (the "Act"), relating
to shares of Lockheed Martin Common Stock, par value $1.00 per share (the
"Lockheed Martin Common Stock"), that are proposed to be issued in connection
with the Combination to holders of outstanding shares of Lockheed Common Stock,
par value $1.00 per share (the "Lockheed Common Stock"), and to holders of
outstanding shares of Martin Marietta Common Stock, par value $1.00 per share
(the "Martin Marietta Common Stock"). This Joint Proxy Statement/ Prospectus
also constitutes the Prospectus of Lockheed Martin filed as part of the
Registration Statement.
 
     This Joint Proxy Statement/Prospectus and the accompanying form of proxy
are first being mailed to the respective stockholders of Lockheed and Martin
Marietta on or about February 11, 1995.
 
     THE SECURITIES TO BE ISSUED PURSUANT TO THIS JOINT PROXY
STATEMENT/PROSPECTUS HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION OR
ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
JOINT PROXY STATEMENT/PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
 
     This Joint Proxy Statement/Prospectus does not cover any resales of the
Lockheed Martin Common Stock or Lockheed Martin Series A Preferred Stock, par
value $1.00 per share (the "Lockheed Martin Series A Preferred Stock"), to be
received by the stockholders of Lockheed or Martin Marietta upon consummation of
the Combination, and no person is authorized to make any use of this Joint Proxy
Statement/Prospectus in connection with any such resale.
 
     The date of this Joint Proxy Statement/Prospectus is February 9, 1995.

THE COMBINATION PROPOSAL
 
     Consideration to be Received by Lockheed Stockholders.  Pursuant to the
Reorganization Agreement and the Pacific Merger Agreement, Pacific Sub will be
merged with and into Lockheed. Lockheed will be the surviving corporation of the
Pacific Sub Merger and will become a wholly owned subsidiary of Lockheed Martin.

Lockheed Common Stock will be converted into the right to receive 1.63 shares of
Lockheed Martin Common Stock and (ii) any outstanding shares of Lockheed Common
Stock owned by Martin Marietta or any subsidiary of Martin Marietta or held by
Lockheed in its treasury will be cancelled and cease to exist. Fractional shares
of Lockheed Martin Common Stock will not be issued in connection with the
Pacific Sub Merger. Holders of Lockheed Common Stock otherwise entitled to a
fractional share will be paid an amount in cash equal to the same fraction of
the fair market value of a whole share of Lockheed Martin Common Stock,
determined as set forth in the Reorganization Agreement. See "THE REORGANIZATION
AGREEMENT -- Consideration to be
 
                                        7
<PAGE>   13
 
Received in the Combination." For a description of the Lockheed Martin Common
Stock, see "DESCRIPTION OF LOCKHEED MARTIN CAPITAL STOCK." For a summary of the
principal differences between the rights of holders of Lockheed Common Stock and
the rights of holders of Lockheed Martin Common Stock, see "COMPARISON OF
STOCKHOLDERS' RIGHTS."
 
     LOCKHEED STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES WITH
THEIR PROXY CARDS.
 
     Consideration to be Received by Martin Marietta Stockholders. Pursuant to
the Reorganization Agreement and the Atlantic Merger Agreement, Atlantic Sub
will be merged with and into Martin Marietta. Martin Marietta will be the
surviving corporation of the Atlantic Sub Merger and will become a wholly owned
subsidiary of Lockheed Martin. Upon consummation of the Atlantic Sub Merger, (i)
each outstanding share of Martin Marietta Common Stock will be converted into
the right to receive one share of Lockheed Martin Common Stock, (ii) each
outstanding share of Martin Marietta Series A Preferred Stock will be converted
into the right to receive one share of Lockheed Martin Series A Preferred Stock
and (iii) any outstanding shares of Martin Marietta Common Stock owned by
Lockheed or any subsidiary of Lockheed will be cancelled and cease to exist. See
"THE REORGANIZATION AGREEMENT -- Consideration to be Received in the
Combination." For a description of the Lockheed Martin Common Stock and Lockheed
Martin Series A Preferred Stock, see "DESCRIPTION OF LOCKHEED MARTIN CAPITAL
STOCK." For a summary of the principal differences between the rights of holders
of Martin Marietta Common Stock and Lockheed Martin Common Stock, see
"COMPARISON OF STOCKHOLDERS' RIGHTS."
 
     MARTIN MARIETTA STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES
WITH THEIR PROXY CARDS.
 
     Ownership of Lockheed Martin After the Combination.  Immediately following
the Combination (i) the former holders of Lockheed Common Stock will
collectively hold approximately 52% of the issued and outstanding shares of
Lockheed Martin Common Stock, and (ii) the former holders of Martin Marietta
Common Stock will collectively hold approximately 48% of the issued and
outstanding shares of Lockheed Martin Common Stock. Immediately following the
Combination, GE, which currently holds 20,000,000 shares of Martin Marietta
Series A Preferred Stock, will hold 20,000,000 shares of Lockheed Martin Series
A Preferred Stock, which will be convertible into approximately 28.9 million
shares of Lockheed Martin Common Stock. Except as required by law or for
specified voting rights in the event of a default under Lockheed Martin's senior
bank facility, a failure to pay dividends under the Lockheed Martin Series A
Preferred Stock or certain mergers, consolidations, business combinations or
share exchanges as described under "DESCRIPTION OF LOCKHEED MARTIN CAPITAL
STOCK -- Series A Preferred Stock -- Voting Rights," the holders of the Lockheed
Martin Series A Preferred Stock will not be entitled to vote on any matter on
which the holders of any voting securities (including the Lockheed Martin Common
Stock) of Lockheed Martin will be entitled to vote. If the Lockheed Martin
Series A Preferred Stock were to be converted immediately after the Combination,
approximately 45% of the shares of Lockheed Martin Common Stock then outstanding
would be held by former holders of Lockheed Common Stock, approximately 42%
would be held by former holders of Martin Marietta Common Stock and
approximately 13% would be held by GE.
 
     Recommendation of Lockheed's Board of Directors: Lockheed's Reasons for the
Combination. The Board of Directors of Lockheed (the "Lockheed Board"), by
unanimous vote, has determined that the Combination is in the best interests of
the holders of Lockheed Common Stock and recommends that holders of Lockheed
Common Stock vote in favor of the Combination Proposal. The decision of the
Lockheed Board to enter into the Reorganization Agreement and to recommend that
stockholders vote in favor of the Combination Proposal is based upon its
evaluation of a number of factors including, among others, the opinion of Morgan
Stanley & Co. Incorporated ("Morgan Stanley"), Lockheed's financial advisor for
the Combination, that the exchange ratio of Lockheed Martin Common Stock for
Lockheed Common Stock reflected in the Reorganization Agreement is fair from a
financial point of view to the stockholders of Lockheed. See "THE
COMBINATION -- Recommendation of Lockheed Board; Lockheed's Reasons for the
Combination" and "-- Fairness Opinions -- Lockheed."

     Recommendation of Martin Marietta's Board of Directors: Martin Marietta's
Reasons for the Combination. The Board of Directors of Martin Marietta (the
"Martin Marietta Board"), by unanimous vote, has determined that the Combination
is in the best interests of the stockholders of Martin Marietta and recommends
that stockholders of Martin Marietta vote in favor of the Combination Proposal.
The decision of the Martin Marietta Board to enter into the Reorganization
Agreement and to recommend that stockholders vote in favor of the Combination
Proposal is based upon its evaluation of a number of factors including, among
others, the opinion of Bear, Stearns & Co. Inc. ("Bear Stearns"), Martin
Marietta's financial advisor for the Combination, to the effect that the
Combination is fair from a financial point of view to the stockholders of Martin
Marietta. See "THE COMBINATION -- Recommendation of Martin Marietta Board;
Martin Marietta's Reasons for the Combination" and "-- Fairness
Opinions -- Martin Marietta."
 
     Conditions to the Combination. The respective obligations of Lockheed and
Martin Marietta to consummate the Combination are subject to the satisfaction of
certain conditions, including approval of the stockholders of both Lockheed and
Martin Marietta, receipt of certain required regulatory approvals, letters from
the independent auditors for Martin Marietta and Lockheed with respect to the
availability of the pooling of interests method of accounting, opinions from tax
counsel for Martin Marietta and for Lockheed with respect to the tax
consequences of the Combination, and confirmation of certain factual matters.
See "THE REORGANIZATION AGREEMENT -- Conditions to the Combination."
 
     Termination of the Reorganization Agreement. The Reorganization Agreement
is subject to termination at the option of either Lockheed or Martin Marietta if
the Combination is not consummated on or before March 31, 1995, and prior to
such time upon the occurrence of certain events. Under certain circumstances,
Lockheed or Martin Marietta may be required to pay to the other a fee in the
amount of $50 million upon the termination of the Reorganization Agreement. See
"THE REORGANIZATION AGREEMENT -- Termination." In addition, in certain cases a
party's expenses, not to exceed $15 million, are reimbursable upon termination.
See "THE REORGANIZATION AGREEMENT -- Expenses."
 
     Regulatory Approvals. The Combination is subject to the requirements of the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), and the rules and regulations thereunder which provide that certain
transactions may not be consummated until required information and materials are
furnished to the Antitrust Division of the Department of Justice (the "Antitrust
Division") and the Federal Trade Commission (the "FTC") and the requisite
waiting period has expired or is terminated. Lockheed and Martin Marietta filed
the required information and materials with the Antitrust Division and the FTC
effective on September 23, 1994. The FTC, which reviewed the transaction, made a
request for additional information on October 21, 1994. Both Lockheed and Martin
Marietta completed their respective submissions of additional information on
December 22, 1994, and the statutory waiting period under the HSR Act expired on
January 11, 1995.
 
     On December 22, 1994, Lockheed, Martin Marietta, and Lockheed Martin
executed an Agreement Containing Consent Order with the FTC staff, which was
provisionally accepted by the FTC on January 11, 1995, subject to further review
at the expiration of a public comment period which expires on March 28, 1995.
After the expiration of the public comment period, the FTC will vote to either
finally accept the Consent Order or withdraw its acceptance of the Consent
Order.
 
     With respect to the HSR Act, Lockheed, Martin Marietta and Lockheed Martin
may consummate the Combination at any time subsequent to the January 11, 1995,
expiration of the HSR waiting period and are not required to delay consummation
until expiration of the public comment period and final FTC acceptance. If the
Combination is consummated prior to final FTC acceptance of the Consent Order
and the FTC withdraws its provisional acceptance of the Consent Order, the FTC
could file an administrative action challenging the Combination in whole or in
part, and could seek divestiture of all or part of Lockheed Martin's assets. Any
adverse FTC decision in any such administrative action would be subject to
review by a federal court of appeals. If the FTC withdraws its provisional
acceptance of the Consent Order prior to consummation of the Combination, the
FTC could seek a temporary restraining order and/or a preliminary injunction
pursuant to Section 13(b) of the Federal Trade Commission Act to prevent
consummation of the transaction subject to the completion of an administrative

     Lockheed, Martin Marietta and Lockheed Martin do not believe that, if the
Combination is consummated, compliance with the Consent Order will have a
material adverse affect on the business, results of operations or financial
condition of Lockheed Martin and its subsidiaries taken as a whole or on the
operating sectors anticipated to be organized by Lockheed Martin as reportable
business segments. See "BUSINESS OF LOCKHEED MARTIN" and "RECENT
DEVELOPMENTS -- Lockheed Plea Agreement."
 
     Lockheed, Martin Marietta and Lockheed Martin have agreed to comply with
the Consent Order during the public comment period and, if the FTC withdraws its
provisional acceptance of the Consent Order, for ten days thereafter. See "THE
COMBINATION -- Regulatory Approvals" for a summary of the material elements of
the Consent Order.
 
     Accounting Treatment. The Combination is expected to qualify as a pooling
of interests for accounting and financial reporting purposes. It is a condition
to the Combination that Lockheed and Martin Marietta each receive from Ernst &
Young LLP, Lockheed's and Martin Marietta's independent auditors, a letter dated
the Merger Date to the effect that they concur with the conclusions of
Lockheed's and Martin Marietta's managements that the transactions contemplated
by the Reorganization Agreement, if consummated, will qualify as transactions to
be accounted for in accordance with the pooling of interests method of
accounting under the requirements of Opinion No. 16, Business Combinations, of
the Accounting Principles Board of the American Institute of Certified Public
Accountants, as amended by applicable pronouncements by the Financial Accounting
Standards Board ("APB No. 16"). See "THE COMBINATION -- Accounting Treatment."
 
     Opinions of Financial Advisors. On August 29, 1994, prior to the execution
of the Reorganization Agreement, Morgan Stanley rendered to the Lockheed Board
its written opinion to the effect that, as of such date, the exchange ratio of
Lockheed Martin Common Stock for Lockheed Common Stock reflected in the
Reorganization Agreement was fair from a financial point of view to the
stockholders of Lockheed. Morgan Stanley has updated its opinion by delivery to
the Lockheed Board of a written opinion dated the date hereof.
 
     On August 27, 1994, Bear Stearns delivered to the Martin Marietta Board its
written opinion to the effect that, as of such date, the Combination was fair
from a financial point of view to the stockholders of Martin Marietta. Bear
Stearns has updated its opinion by delivery to the Martin Marietta Board of a
written opinion dated the date hereof.
 
     Lockheed and Martin Marietta stockholders are urged to read carefully the
opinions of Morgan Stanley and Bear Stearns, respectively, which are set forth
in their entirety as Appendices II and III to this Joint Proxy
Statement/Prospectus, for a description of the procedures followed, the factors
considered and the assumptions made by Morgan Stanley and Bear Stearns in
rendering their respective opinions. See "THE COMBINATION -- Fairness Opinions."
 
     Certain Federal Income Tax Consequences. The Combination has been
structured to qualify as a nontaxable exchange under the Internal Revenue Code
of 1986, as amended (the "Code"). It is a condition to the Combination that
Lockheed receive an opinion from O'Melveny & Myers (counsel to Lockheed) and
that Martin Marietta receive an opinion from King & Spalding (tax counsel to
Martin Marietta) to the effect that no gain or loss will be recognized by
Lockheed or Martin Marietta, as the case may be, or their respective
stockholders in connection with the Combination (other than with respect to cash
received in lieu of fractional shares by holders of Lockheed Common Stock). See
"THE COMBINATION -- Certain Federal Income Tax Consequences."
 
     Appraisal Rights. Holders of Lockheed Common Stock are not entitled to
dissenters' or appraisal rights in connection with the Pacific Sub Merger
because the Lockheed Common Stock is listed on a national securities exchange
and the shares of Lockheed Martin Common Stock that such holders will be
entitled to receive in the Pacific Sub Merger will also be listed on a national
securities exchange. Holders of Martin Marietta Common Stock are not entitled to
dissenters' or appraisal rights in connection with the Atlantic Sub Merger
because the Martin Marietta Common Stock is listed on a national securities
exchange.
 
     The holder of the outstanding shares of Martin Marietta Series A Preferred
Stock, GE, is entitled to exercise appraisal rights under Title 3, Subtitle 2 of
the MGCL. However, the management of GE has agreed to recommend to its Board of
Directors that GE not assert any appraisal rights under the MGCL in
 
                                       10
<PAGE>   16
 
connection with the transactions contemplated by the Reorganization Agreement
and that GE vote its shares of Martin Marietta Series A Preferred Stock in favor
of the Combination Proposal. See "THE COMBINATION -- Appraisal Rights."
 
SPECIAL CONSIDERATIONS
 
     Matters of special consideration to be noted by stockholders in determining
whether or not to vote in favor of the Combination Proposal include the
following: the possibility that currently unanticipated difficulties may arise
in integrating the operations of two major corporations; the risk that the
synergies expected from combining the operations of Lockheed and Martin Marietta
may not be realized; the possible adverse impact upon the combined operations of
Lockheed Martin of the plea agreement of Lockheed relating to violations of the
Foreign Corrupt Practices Act by a Lockheed division primarily engaged in the
production of military aircraft, including the possibility of suspension or
debarment from future government contracting, and the related U.S. Department of
State's policy to prospectively deny defense-related export privileges to that
division, subject to the grant on a case-by-case basis of transaction related
exceptions; the transition costs and expenses expected to be incurred in
connection with consummating the Combination and integrating the operations of
Lockheed and Martin Marietta, which costs and expenses (certain of which will
not be allowable under the Federal Acquisition Regulations) are currently
estimated to total approximately $850 million and will be charged against the
earnings of Lockheed Martin, primarily in 1995; and the number and terms of
authorized shares of Lockheed Martin Series Preferred Stock which may be
authorized for issuance by the Board of Directors of Lockheed Martin without
further stockholder approval. See "BUSINESS OF LOCKHEED MARTIN"; "RECENT
DEVELOPMENTS -- Lockheed Plea Agreement"; Note 3 under "NOTES TO UNAUDITED PRO
FORMA COMBINED CONDENSED FINANCIAL STATEMENTS"; "DESCRIPTION OF LOCKHEED MARTIN
CAPITAL STOCK"; and "THE COMBINATION -- Recommendation of Lockheed Board;
Lockheed's Reasons for the Combination"; and "-- Fairness Opinions."
 
THE PLAN PROPOSALS
 
     The Lockheed Board and the Martin Marietta Board believe that the future
growth and success of Lockheed Martin after the Combination will be enhanced by
the ability of Lockheed Martin and its subsidiaries to attract, motivate, retain
and reward talented and experienced individuals in a position to contribute to
Lockheed Martin's success by providing an opportunity to obtain an increased
proprietary interest in Lockheed Martin's performance. Therefore, the Lockheed
Board and the Martin Marietta Board recommend that their respective stockholders
approve the adoption of the Lockheed Martin Omnibus Plan and the Lockheed Martin
Directors Plan. See "LOCKHEED MARTIN 1995 OMNIBUS PERFORMANCE AWARD PLAN" and
"LOCKHEED MARTIN DIRECTORS DEFERRED STOCK PLAN."

SUMMARY SELECTED HISTORICAL AND UNAUDITED PRO FORMA
COMBINED CONDENSED FINANCIAL INFORMATION
 
     The summary selected historical financial information of Lockheed and
Martin Marietta for fiscal years 1993, 1992 and 1991 presented below, with the
exception of the balance sheet data for 1991, has been derived from the audited
consolidated financial statements of Lockheed and Martin Marietta incorporated
by reference herein. The historical balance sheet data for 1991 and the summary
financial information presented below for 1990 and 1989 have been derived from
audited consolidated financial statements previously filed with the Commission
but not incorporated by reference in this Joint Proxy Statement/Prospectus. The
unaudited pro forma combined financial data give effect to the Combination by
combining the financial statement data of Lockheed and Martin Marietta at and
for each year in the three fiscal year period ended December, 1993 and at and
for the fiscal nine months ended September, 1994 and 1993, on the pooling of
interests method of accounting. For a description of pooling of interests
accounting with respect to the Combination, see "THE COMBINATION -- Accounting
Treatment." The unaudited pro forma combined financial data are not necessarily
indicative of actual or future operating results or financial position that
would have occurred or will occur upon consummation of the Combination.
Historical financial data at and for the fiscal nine month periods ended
September, 1994 and 1993 with respect to Lockheed and Martin Marietta have been
derived from unaudited financial statements filed with the Commission, and in
the opinion of Lockheed's and Martin Marietta's respective managements, include
all adjustments necessary for a fair presentation of the results of operations
and financial position at and for each of the interim periods presented. No
material adjustments other than of a normal recurring nature were made, except
for certain 1993 nonrecurring adjustments in Lockheed's Aeronautical Systems
segment described in Item 2 of Lockheed's Quarterly Report on Form 10-Q for the
quarter ended September 25, 1994. The information shown below should be read in
conjunction with the historical consolidated financial statements of Lockheed
and Martin Marietta, including the respective notes thereto, which are
incorporated by reference in this Joint Proxy Statement/Prospectus and in
conjunction with the unaudited pro forma combined condensed financial
statements, including the notes thereto, appearing elsewhere in this Joint Proxy
Statement/Prospectus. Results for the fiscal nine months ended September, 1994
are not necessarily indicative of results which may be expected for any other
interim period or for the year as a whole. See "INCORPORATION OF CERTAIN
DOCUMENTS BY REFERENCE", "UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL
STATEMENTS" and "NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL
STATEMENTS."

COMPARATIVE PER SHARE MARKET PRICE INFORMATION
 
     The Lockheed Common Stock and the Martin Marietta Common Stock are listed
on the New York Stock Exchange, Inc. ("NYSE") and certain other stock exchanges.
On August 29, 1994, the last full trading day prior to the public announcement
of the proposed Combination, the closing price on the NYSE Composite Tape was
$66 per share of Lockheed Common Stock and $48 1/4 per share of Martin Marietta
Common Stock. On February 8, 1995, the most recent practicable date prior to the
printing of this Joint Proxy Statement/Prospectus, the closing price on the NYSE
Composite Tape was $74 1/8 per share of Lockheed Common Stock and $45 3/4 per
share of Martin Marietta Common Stock. Holders of Lockheed Common Stock and
Martin Marietta Common Stock are urged to obtain current market quotations prior
to making any decision with respect to the Combination. See "COMPARATIVE PER
SHARE MARKET PRICE AND DIVIDEND INFORMATION."
 
LISTING OF LOCKHEED MARTIN COMMON STOCK; QUARTERLY DIVIDEND
 
     Lockheed Martin expects to apply for listing of the Lockheed Martin Common
Stock on the NYSE and it is anticipated that such shares will trade on the NYSE
upon official notice of issuance under the symbol LMT. See "THE
COMBINATION -- Stock Exchange Listing."
 
     Except as described in the next paragraph, it is expected that the
quarterly dividend with respect to Lockheed Martin Common Stock will be at the
annual rate of $1.40 per share, subject to approval and declaration by the
Lockheed Martin Board. On an equivalent share basis this would represent $2.28
per equivalent share of Lockheed Common Stock and $1.40 per equivalent share of
Martin Marietta Common Stock. The annual rate of $1.40 per share of Lockheed
Martin Common Stock is intended to maintain the current indicated annual
dividend rate for the holders of Lockheed Common Stock and represents an
increase of approximately 46% over the current indicated annual dividend rate
for the holders of Martin Marietta Common Stock (the current indicated annual
dividend rates being based on the most recent quarterly dividend payments of
$0.57 per share for Lockheed and $0.24 per share for Martin Marietta). The
payment of dividends by Lockheed Martin will, however, necessarily be dependent
on business conditions, Lockheed Martin's financial position and earnings, and
other factors.
 
     In connection with a proposed settlement of certain stockholder litigation,
it is contemplated that Lockheed Martin will agree to pay a regular quarterly
dividend of $0.40 (rather than $0.35) per share of Lockheed Martin Common Stock
for each of the first three quarters after consummation of the Combination and
court approval of the settlement, subject to certain conditions. See "THE
COMBINATION -- Certain Litigation."

the affirmative vote, in person or by proxy, of the holders of a majority of the
shares of Lockheed Common Stock outstanding on the Lockheed Record Date is
required to approve and adopt the Reorganization Agreement and the Pacific

     Martin Marietta. The Martin Marietta Board has fixed the close of business
on February 7, 1995, as the Martin Marietta Record Date. Only holders of record

Participants in the Martin Marietta Dividend Reinvestment Plan and certain of
Martin Marietta's benefit plans are entitled to one vote for each full share of
Martin Marietta Common Stock held under each plan. Shares of Martin Marietta
Common Stock held in accounts under the Dividend Reinvestment Plan will be

     Bankers Trust Company, as trustee of the Martin Marietta Corporation
Performance Sharing Plan and the Martin Marietta Corporation Savings and
Investment Plan for Hourly Employees, reported that it held, as of December 31,
1994, 8,486,374 shares of Martin Marietta Common Stock (approximately 8.83% of
the Martin Marietta Common Stock outstanding on December 31, 1994). Bankers
Trust Company expressly disclaimed beneficial ownership of these shares. Each
participant in these plans will receive an instruction card on which the
participant may direct Bankers Trust Company as to the manner in which shares of
Martin Marietta Common Stock allocated to the participant's plan account are to
be voted. In addition, as of December 31, 1994, Bankers Trust Company reported
beneficial ownership of 1,810,544 shares of Martin Marietta Common Stock
(approximately 1.88% of the Martin Marietta Common Stock outstanding on December
31, 1994) as trustee for various trust and employee benefit plans not associated
with Martin Marietta.
 
     Effective August 15, 1994, Martin Marietta Common Stock was offered as an
investment option to participants in the Sandia Corporation Savings and Security
Plan and the Sandia Corporation Savings and Income Plan. Participants in these
plans may direct Fidelity Management Trust Company, as trustee for these plans,
as to the manner in which shares of Martin Marietta Common Stock allocated to
the plan participant's account are to be voted. Effective October 1, 1994,
Martin Marietta Common Stock was also offered as an investment option to
participants in the Martin Marietta Corporation Performance Sharing Plan for
Puerto Rico Employees. Participants in that plan may direct Bankers Trust
Company as to the manner in which shares of Martin Marietta Common Stock
allocated to the plan participant's account are to be voted. Participants in the
Martin Marietta Energy Systems, Inc. 401(k) Savings Plan for Hourly Employees,
the Martin Marietta Energy Systems, Inc. 401(k) Savings Plan for Salaried
Employees and the Martin Marietta Energy Systems Inc. Savings Plan for Salaried
and Hourly Employees may direct Chemical Bank, the trustee of these plans, as to
the manner in which shares of Martin Marietta Common Stock allocated to the plan
participant's account are to be voted.
 
     If a participant under any of the above plans does not return a voting
instruction card in a timely manner or returns a card without indicating any
voting instructions, subject to the requirements of applicable law, the shares
will be voted in the same proportion as shares for which voting instructions are
received for that plan.
 
     The Martin Marietta Common Stock and Martin Marietta Series A Preferred
Stock will vote together as a single class on the proposal to approve the
Reorganization Agreement and the Atlantic Merger Agreement. Each holder of
record, as of the Martin Marietta Record Date, of Martin Marietta Common Stock
is entitled to cast one vote per share in person or by proxy, on each proposal
properly presented at the Martin Marietta Meeting. GE, as the holder of all of
the Martin Marietta Series A Preferred Stock, is entitled to cast, in person or
by proxy, 28,941,466 votes, representing the number of shares of Martin Marietta
Common Stock into which the Martin Marietta Series A Preferred Stock is
convertible. As a holder of Martin Marietta Series A Preferred Stock, GE is not
entitled to vote on either of the Plan Proposals. The presence, in person or by
proxy, of the holders of a majority of the combined voting power of the
outstanding shares of Martin Marietta Common Stock and Martin Marietta Series A
Preferred Stock is necessary to constitute a quorum with respect to the
Combination Proposal at the Martin Marietta Meeting. The presence, in person or
by proxy, of the holders of a majority of the outstanding shares of Martin
Marietta Common Stock is necessary to constitute a quorum with respect to each
of the Plan Proposals at the Martin Marietta Meeting.

     Under Martin Marietta's Charter and the MGCL, the affirmative vote, in
person or by proxy, of the holders of record of a majority of the combined
voting power of the shares of Martin Marietta Common Stock and Martin Marietta
Series A Preferred Stock outstanding on the Martin Marietta Record Date, voting
together as a single class, is required to approve the Reorganization Agreement
and the Atlantic Merger Agreement. The management of GE has agreed to support
the Combination and to recommend to its Board of Directors that GE's shares of
Martin Marietta Series A Preferred Stock be voted in favor thereof. Assuming GE
votes in favor of the Combination Proposal, the Combination Proposal will be
approved if the holders of approximately 35% of the outstanding shares of Martin
Marietta Common Stock vote in favor thereof. If GE were not to vote in favor of
the Combination Proposal, the Combination Proposal would be approved only if
approximately 65% of the outstanding shares of Martin Marietta Common Stock
voted in favor thereof. See "OWNERSHIP OF LOCKHEED, MARTIN MARIETTA AND LOCKHEED
MARTIN -- Martin Marietta." Approval of the adoption of each of the Plan
Proposals requires the affirmative vote of the holders of a majority of the
shares of Martin Marietta Common Stock issued and outstanding on the Martin
Marietta Record Date. In addition, the Combination Proposal and each of the Plan
Proposals must also be approved by the holders of shares of Lockheed Common
Stock as described above.
 
PROXIES
 
     All shares of Lockheed Common Stock, Martin Marietta Common Stock and
Martin Marietta Series A Preferred Stock represented by properly executed
proxies received prior to or at the Lockheed Meeting, or the Martin Marietta
Meeting, as the case may be, and not revoked, will be voted in accordance with
the instructions indicated in such proxies. If no instructions are indicated on
a properly executed returned proxy, such proxies will be voted FOR the
Combination Proposal and FOR each of the Plan Proposals. A properly executed
proxy marked "ABSTAIN," although counted for purposes of determining whether
there is a quorum and for purposes of determining the aggregate voting power and
number of shares represented and entitled to vote at the applicable Special
Meeting, will not be voted. Accordingly, since the affirmative vote of a
majority of the aggregate voting power (in the case of Lockheed as it relates to
the Combination Proposal and in the case of Martin Marietta as it relates to the
Combination Proposal and each of the Plan Proposals), or a majority of the
aggregate voting power present in person or by proxy at the Special Meeting (in
the case of Lockheed as it relates to each of the Plan Proposals) is required
for approval of a particular proposal, a proxy marked "ABSTAIN" will have the
effect of a vote against the proposal. Shares represented by "broker non-votes"
(i.e., shares held by brokers or nominees which are represented at a meeting but
with respect to which the broker or nominee is not empowered to vote on a
particular proposal) will be counted for purposes of determining whether there
is a quorum at the applicable Special Meeting but, in the case of Lockheed as it
relates to each of the Plan Proposals, will not be counted as present in person
or by proxy. In accordance with NYSE rules, brokers and nominees are precluded
from exercising their voting discretion on the Combination Proposal and the Plan
Proposals and thus, absent specific instructions from the beneficial owner of
such shares, are not empowered to vote such shares on the Combination Proposal
or the Plan Proposals. Therefore, since the affirmative vote of a majority of
the aggregate voting power is required for approval of the Combination Proposal,
and in the case of Martin Marietta each of the Plan Proposals, a "broker
non-vote" with respect to the Combination Proposal, and in the case of Martin
Marietta each of the Plan Proposals, will have the effect of a vote against the
Combination Proposal and in the case of Martin Marietta each of the Plan
Proposals.
 
     At the time this Joint Proxy Statement/Prospectus was filed with the
Commission, neither the Lockheed Board nor the Martin Marietta Board was aware
that any matter not referred to herein would be presented for action at their
respective Special Meetings. It is intended that discretionary authority
conferred in the proxies will be exercised with respect to the vote on any
matters incident to the conduct of the respective Special Meetings.
 
     A stockholder may revoke his or her proxy at any time prior to its use by
delivering to the Secretary of Lockheed or Martin Marietta, as the case may be,
a signed notice of revocation or a later dated signed proxy or by attending the
applicable Special Meeting and voting in person. Attendance at the Lockheed
Meeting or the Martin Marietta Meeting will not in itself constitute the
revocation of a proxy.
 
                                       18

     It is the general practice of Lockheed and Martin Marietta to keep
confidential proxy cards, ballots and voting tabulations that identify
individual stockholders, except where disclosure is mandated by law, such
disclosure of a stockholder's vote is expressly requested by that stockholder or
during a contested election. It is also the general practice that the tabulators
and inspectors of election be independent and not employees of Lockheed or
Martin Marietta.
 
     The cost of solicitation of proxies will be paid by Lockheed for Lockheed
proxies and by Martin Marietta for Martin Marietta proxies. In addition to
solicitation by mail, arrangements will be made with brokerage houses and other
custodians, nominees and fiduciaries to send proxy material to beneficial
owners; and Lockheed, or Martin Marietta, as the case may be, will, upon
request, reimburse them for their reasonable expenses in so doing. Lockheed has
retained Georgeson & Company Inc. to aid in the solicitation of proxies and to
verify certain records related to the solicitation at a fee of $15,000 plus
expenses. Martin Marietta has retained Morrow & Co., Inc. to aid in the
solicitation of proxies and to verify certain records related to the
solicitation at a fee of $25,000 plus expenses. To the extent necessary in order
to ensure sufficient representation at its Special Meeting, Lockheed or Martin
Marietta may request by telephone or telegram the return of proxies. The extent
to which this will be necessary depends entirely upon how promptly proxies are
returned. Stockholders are urged to send in their proxies without delay.

                                THE COMBINATION
 
BACKGROUND
 
     Since 1985, the Federal defense budget for research, development, test and
evaluation and procurement has been reduced by almost two-thirds in constant,
inflation adjusted dollars. This reduction has caused continued pressures on
participants in the aerospace/defense industry to consolidate in order to
maintain critical mass and production economies. Both Lockheed and Martin
Marietta have been active participants in the consolidation of the industry. The
major acquisitions during this period involving Lockheed and Martin Marietta
included the following: in 1986, Lockheed purchased Sanders Associates, Inc., a
defense and commercial electronics company, for approximately $1.2 billion; in
1993, Lockheed purchased the Fort Worth Division of General Dynamics for
approximately $1.5 billion; in 1988, Martin Marietta purchased Gould Inc.'s
Ocean Systems Division for approximately $117 million; in 1993, Martin Marietta
effected a combination with the GE Aerospace businesses in a transaction valued
at approximately $3.05 billion; and, in 1994, Martin Marietta acquired the
General Dynamics Space Systems Division for approximately $161 million.
 
     In light of the anticipated continuation of decreases in military spending
and the accelerating consolidation in the aerospace/defense industry, Lockheed's
management and the Lockheed Board have periodically reviewed Lockheed's
strategic planning, including but not limited to the possibility of making
acquisitions, potential internal investment and entering into joint ventures and
business combinations with companies engaged in a similar or related business.
Lockheed retained Morgan Stanley to advise it regarding possible strategic
alternatives. Lockheed's strategic priorities as stated by management and the
Lockheed Board are to maximize long-term stockholder value as a continuing
entity by strengthening Lockheed's position in a consolidating industry and
expanding into related businesses, while keeping Lockheed financially sound
without excessive leverage.
 
     In response to the significant reduction in the Federal defense budget
referred to above and in anticipation of continued consolidation in the
aerospace/defense industry, in 1990 Martin Marietta adopted what it refers to as
its "Peace Dividend Strategy." This strategy called for (i) exploiting expansion
opportunities resulting from the consolidation in the aerospace/defense
industry, thereby maintaining the
 
                                       19
<PAGE>   25
 
technological and programmatic business base for long-term industry leadership;
(ii) aggressively expanding Martin Marietta's civil, commercial and
international businesses in closely related markets such as energy, information,
materials and services; and (iii) pursuing other steps to enhance stockholder
value, such as a share repurchase program. Management of Martin Marietta has
periodically reviewed the bases for the strategy with the Martin Marietta Board
and has actively pursued executing this strategy. The Martin Marietta Board
believes that a new phase of the consolidation process is now underway, in which
successful companies will seek to improve operating efficiencies, position
themselves competitively across a number of key industry segments, facilitate
efficient investment in research and development and expand in complementary
commercial, civil and international markets, thereby balancing their risk
profiles and potentially emerging as strategic participants in the restructured
aerospace/defense industry.
 
     On March 19, 1994, Daniel M. Tellep, Chairman of the Board and Chief
Executive Officer of Lockheed, telephoned Norman R. Augustine, Chairman of the
Board and Chief Executive Officer of Martin Marietta, regarding the possibility
of a business combination between Lockheed and Martin Marietta. Messrs. Tellep
and Augustine agreed that representatives of the two companies should meet to
explore various possibilities.
 
     On March 22, 1994, members of senior management of Lockheed and Martin
Marietta, including Messrs. Tellep and Augustine, held initial discussions
regarding a possible transaction between the two companies. Messrs. Tellep and
Augustine both stressed that neither Lockheed nor Martin Marietta was for sale.
The structure discussed was based upon the concept of a "merger of equals"
(i.e., a strategic combination of two similarly-sized companies in which neither
company is acquiring the other and each has an approximately equal voice in the
management of the combined entity) and each executive presented his position as
to the parameters of such a business combination. Further discussions regarding
the business rationale underlying a business combination, possible synergies to
be realized and structural details of a potential combination of the two
companies occurred at a meeting of senior executives held on March 25, 1994.
 
     On March 29, 1994, legal representatives of each company met to discuss,
among other things, the possible structure of a business combination and related
legal issues. The parties also negotiated and executed a Confidentiality and
Standstill Agreement, dated March 29, 1994 (the "Confidentiality and Standstill
Agreement"), relating, among other things, to the information to be provided by
each company to the other and limiting the ability of each party for three years
to acquire any voting securities or assets of, or solicit proxies or make a
public announcement of a proposal for any extraordinary transaction with respect
to, the other party. Both parties believed the Confidentiality and Standstill
Agreement was necessary and appropriate since neither company was for sale.
 
     On March 30, 1994, meetings occurred between members of senior financial
management of Lockheed and Martin Marietta, as well as the investment bankers
for each company, to discuss, among other things, the financial aspects of a
possible business combination, including valuation concepts. Further discussion
occurred concerning the business rationale and synergies that might be obtained
from the transaction.
 
     During a regularly scheduled meeting of the Lockheed Board on April 4,
1994, Mr. Tellep informed the Lockheed Board of the discussions with senior
management of Martin Marietta. Presentations regarding a possible business
combination were made by senior management, and outside legal counsel for
Lockheed gave a presentation on the duties of directors in considering a
business combination. Representatives of Morgan Stanley were also present. At
that meeting, the Lockheed Board decided to discontinue further discussions with
Martin Marietta pending further study by Lockheed's senior management of the
issues raised by a possible business combination.
 
     During a regularly scheduled meeting of the Martin Marietta Board on April
28, 1994, an initial presentation regarding a possible business combination with
Lockheed was made to the Martin Marietta Board by senior management.
Representatives of Bear Stearns were also present and participated. The
presentation to and discussion by the Martin Marietta Board was wide ranging and
included, among other things, a review of (a) management's current view of the
financial condition and prospects of Martin Marietta over the period encompassed
by the corporation's planning process; (b) the strategic alternatives available
to Martin Marietta and their possible implications in light of management's
objective of continuing stockholder
 
                                       20
<PAGE>   26
 
value growth; and (c) the current state of the industry consolidation and
potential consolidation opportunities and trends in the foreseeable future. A
review of Lockheed's organization, businesses, management and financials was
provided to the Martin Marietta Board, together with a discussion of the
potential strategic benefits of a business combination. A summary of the
financial implications was also provided. In addition, Bear Stearns presented an
independent view of possible market reactions and competitive responses to the
potential combination.
 
     During a regularly scheduled meeting of the Lockheed Board on May 9, 1994,
Mr. Tellep gave the Lockheed Board management's assessment of the strategic
options then available to Lockheed. Mr. Tellep reviewed Lockheed's strategic
situation, including the continued cuts in defense spending and the challenging
environment for foreign military and non-defense sales. Possible acquisition
candidates which had been identified by management were regarded as either too
expensive or unattractive for other reasons. He stated that a "merger of equals"
with a company in the same or similar business continued to be a viable
alternative. Mr. Tellep also described to the Lockheed Board possible joint
ventures and the possibility of a share repurchase program. Mr. Tellep undertook
to present strategic recommendations to the Lockheed Board at its regularly
scheduled meeting in June 1994.
 
     On June 14, 1994, the Chief Executive Officers and Chief Financial Officers
of Lockheed and Martin Marietta met to discuss, among other things, the basic
organizational structure of a combined company, valuation principles and the
structure of its board of directors. Representatives of Lockheed noted that, due
to the changing environment in the aerospace/defense industry, management of
Lockheed believed that a significant management presence in the Washington, D.C.
area was desirable and, accordingly, management of Lockheed had considered
moving Lockheed's executive offices to the East Coast. The parties agreed that
the location of the headquarters of the combined entity should be in the
Washington, D.C. area.
 
     During the regularly scheduled meeting of the Lockheed Board on June 20,
1994, Mr. Tellep gave an update on the strategic options available to Lockheed.
He noted the continued cuts in U.S. defense spending and the challenges to
various defense programs, including some of the programs in which Lockheed was
involved. After discussion, the Lockheed Board determined to defer any major
decisions until the strategic situation was further defined. The Lockheed Board
indicated a strong desire for additional details and encouraged continued
discussions with Martin Marietta.
 
     On June 24, 1994, during a regularly scheduled meeting, the Martin Marietta
Board was provided a status report concerning the activities that had transpired
since their April 28 meeting.
 
     On June 30, 1994, Messrs. Tellep and Augustine met to review the progress
of the discussions regarding a possible business combination and to discuss
issues requiring resolution in future meetings and organizational issues,
including their respective roles in a combined company.
 
     On July 13, 1994, the Chief Executive Officers and Chief Financial Officers
of Lockheed and Martin Marietta met to discuss several matters, including but
not limited to a proposed management philosophy for a combined company,
potential consolidation efficiencies, staffing, plans for contacting major
customers in the Department of Defense and NASA and the basis on which due
diligence reviews of the respective companies would occur. In addition, the
parties discussed the potential location of the executive offices of a combined
company and concluded for efficiency and economic reasons that the current
Martin Marietta headquarters facility would be used.
 
     On July 20, 21 and 29, 1994, members of senior management of each of
Lockheed and Martin Marietta as well as their respective legal and financial
advisors met to continue discussions regarding the structure, financial matters
and corporate governance matters relating to a possible business combination. In
connection with these meetings, Mr. Augustine telephoned the members of the
Martin Marietta Board and provided them with an overview of the status of
discussions with Lockheed and the various issues under consideration.
 
     At a special meeting of the Martin Marietta Board on July 27, 1994, the key
management and organizational concepts of the combination were discussed,
together with management's views of the necessary near term actions required to
resolve current open issues.
 
                                       21
<PAGE>   27
 
     During a regularly scheduled meeting of the Martin Marietta Board on July
28, 1994, the progress of the discussions with Lockheed was discussed in detail.
In this regard, Mr. Augustine made a presentation concerning management's review
of potential business combinations and other strategic opportunities available
to Martin Marietta that would increase the probability that Martin Marietta
would retain the ability to efficiently produce advanced technology products and
services in view of the continuing decline of the Federal defense budget for
research, development, test and evaluation, and procurement; the anticipated
continuation of decreases in military spending; and the accelerating
consolidation in the defense and aerospace industries. Thereafter, Mr. Bennett,
Martin Marietta's Chief Financial Officer, made a presentation to the Martin
Marietta Board in which he discussed, among other things, the financial risks
and rewards associated with the various strategic possibilities described by Mr.
Augustine. Additionally, Martin Marietta's General Counsel, Mr. Menaker,
reviewed the legal parameters associated with the presentations by Messrs.
Augustine and Bennett. Thereafter, management generally reminded the Martin
Marietta Board of Martin Marietta's strategic direction, presented management's
views as to the likelihood of continued industry consolidations, and discussed
the strategic benefits and disadvantages of a possible "merger of equals" with
Lockheed. A variety of pro forma financial analyses were shared with the Martin
Marietta Board, including a discussion of exchange ratios and dividend policies
and their effects on stockholder value. The Martin Marietta Board concluded that
management should proceed with due diligence and negotiation of the terms of a
possible transaction.
 
     At a regularly scheduled meeting of the Lockheed Board on August 1, 1994,
Mr. Tellep gave a presentation on the strategic options available to Lockheed.
Mr. Tellep reminded the Lockheed Board of the continuing decline in the U.S.
defense budget, accelerating defense and aerospace industry consolidation, as
well as the potential growth for non-defense businesses. He summarized the
financial forecast for Lockheed and each of its divisions. Mr. Tellep discussed
with the Lockheed Board various strategic alternatives, including but not
limited to making no strategic moves but focusing on internal investment and
actions to improve competitiveness, acquiring another company in a similar or
related business, entering into a joint venture with respect to part of its
business or merging with another company to strengthen Lockheed's lines of
business and add new markets and opportunities. Mr. Tellep summarized for the
Lockheed Board management's evaluation of each of these alternatives. The
Lockheed Board, after discussion of these various alternatives, preliminarily
concluded that (i) focusing on internal investment, although possibly a viable
alternative, involved significant risks and limited opportunities, (ii)
potential acquisitions were either too expensive or not otherwise appropriate,
(iii) potential joint ventures considered were not viable or appropriate for
various reasons, and (iv) a "merger of equals" offered the best possibility to
benefit Lockheed and its stockholders. Senior management of Lockheed and outside
legal counsel then gave a presentation to the Lockheed Board regarding a
possible business combination with Martin Marietta, including a summary of the
major programs and products of Martin Marietta, potential synergies between the
two companies, consolidation opportunities, the financial situation and
management of Martin Marietta, the status of the discussions with Martin
Marietta, the countervailing considerations associated with a business
combination with Martin Marietta and the duties of the directors in considering
a business combination. It was noted that a business combination with Martin
Marietta would result in a leading aerospace company providing critical mass and
economies of scale. The business combination would enhance the combined
company's position in commercial markets, provide potential for consolidation
savings and create a broader platform upon which to grow the combined business,
thus reducing dependence on any single program and the associated risks of
program cancellation. A business combination of equals with Martin Marietta
would also result in a capital structure with essentially no additional leverage
(as compared to a cash acquisition which could require significant additional
leverage) and increased cash flow potential which in turn would offer the
combined business the flexibility to pursue future opportunities. After
discussion, the Lockheed Board authorized management to proceed with due
diligence of Martin Marietta and to continue discussions regarding a possible
business combination.
 
     During August 1994, representatives of Lockheed and Martin Marietta
continued to conduct business, financial, accounting and legal due diligence, to
discuss legal issues and to negotiate the terms of the Reorganization Agreement.
The discussions included the possible ramifications of the June 1994 indictment
of Lockheed by a federal grand jury sitting in Atlanta, Georgia and the
possibility of suspension or debarment
 
                                       22
<PAGE>   28
 
of Lockheed from future government contracting. The indictment alleged
violations of the Foreign Corrupt Practices Act and other criminal statutes by
Lockheed and two of its employees. Also discussed was the notice received by
Lockheed from the U.S. Department of State which provides that, as a result of
the indictment, it will be the Department's policy prospectively to deny
defense-related export privileges to an unincorporated division of Lockheed,
primarily engaged in the manufacture of military aircraft for sale to the United
States Department of Defense and to foreign governments, subject to the grant on
a case-by-case basis of transaction related exceptions.
 
     In addition, during August 1994, Mr. Tellep and/or Mr. Augustine met with
various representatives of the Department of Defense and other major
governmental customers to advise them of the possibility of a business
combination between Lockheed and Martin Marietta.
 
     At a special meeting of the Lockheed Board on August 20, 1994, Mr. Tellep
reviewed with the Lockheed Board the events since the August 1, 1994 Lockheed
Board meeting. He described for the Lockheed Board the elements of a business
combination that had been preliminarily agreed to and the remaining open issues.
Members of senior management then gave an extensive presentation concerning
financial projections for the combined business, the proposed exchange ratios of
Lockheed and Martin Marietta stock for stock of the combined business and the
results of the business, financial, accounting and legal due diligence of Martin
Marietta. Representatives of Morgan Stanley then gave a presentation concerning,
among other things, Lockheed's strategic alternatives, the benefits of a "merger
of equals," the benefits of a business combination with Martin Marietta, certain
financial information regarding Lockheed, Martin Marietta and the combined
business, market information regarding both companies, the proposed range of
exchange ratios and the impact on Lockheed's stockholders. Outside legal counsel
also discussed with the Lockheed Board certain legal issues relating to a
possible business combination with Martin Marietta. At the conclusion of that
meeting, the Lockheed Board authorized management to continue to conduct due
diligence and negotiate with Martin Marietta.
 
     At a special meeting of the Martin Marietta Board on August 27, 1994, Mr.
Augustine reviewed for the Martin Marietta directors the background of the
proposed transaction, including the chronology of events and developments since
March when he and Mr. Tellep had the initial discussions referred to above. Mr.
Augustine reviewed the deliberations with respect to this matter at the
intervening meetings of the Martin Marietta Board. Mr. Augustine also provided
his overview of industry conditions (including the contraction of the defense
budget) and the outlook for the industry generally and for Martin Marietta in
particular. Martin Marietta's "Peace Dividend Strategy" was also discussed as
were the perceived benefits of a "merger of equals" with Lockheed in light of
that strategy. (See "-- Recommendation of Martin Marietta Board; Martin
Marietta's Reasons for the Combination.") Mr. Augustine reviewed the need for
regulatory and stockholder approvals and discussed various other aspects of the
proposed transaction. Senior management reported on the results of Martin
Marietta's "due diligence" review of Lockheed's business, financial condition
and other matters. Senior management also described the pooling of interests
method of accounting expected to be used in connection with the Combination, as
well as the expected tax treatment of the Combination. Senior management also
reviewed the negotiations and analysis leading to the proposed exchange ratio
and the proposed dividend of $1.40 per share (which would be an increase over
the current annualized dividend to holders of Martin Marietta Common Stock).
Representatives of Bear Stearns reviewed various aspects of the proposed
transaction with the Martin Marietta directors, analyzing factors such as stock
market trends, historical price to earnings ratios and relative contributions,
certain financial information regarding Martin Marietta and the proposed
combined entity and the impact of the transaction on Martin Marietta
stockholders. Bear Stearns delivered to the Martin Marietta Board its written
opinion to the effect that the Combination was fair, from a financial point of
view, to the stockholders of Martin Marietta. Outside legal counsel reviewed
various legal aspects of the proposed Combination, including the duties of the
directors with respect thereto. Mr. Menaker, Martin Marietta's General Counsel,
reviewed in detail with the Martin Marietta Board the various legal
considerations concerning the advisability of adopting a stockholders rights
plan. Thereafter, the Martin Marietta Board reviewed the terms of, and then
approved, a stockholder rights plan. At the conclusion of the meeting the Martin
Marietta Board unanimously approved the Reorganization Agreement and the
transactions contemplated thereby.

     At a special meeting of the Lockheed Board on August 29, 1994, Mr. Tellep
and other senior management reviewed with the Lockheed Board the strategic
option reviews which had occurred since 1993, the chronology of the discussions
with Martin Marietta and the reasons for and benefits of a business combination
with Martin Marietta. An update on the due diligence efforts was given to the
Lockheed Board including, but not limited to, a review of the adequacy of
reserves taken for Martin Marietta fixed priced contracts at the time of Martin
Marietta's transaction with GE (see "THE STANDSTILL AGREEMENT"), factors
regarding the marketing, pricing, and risks associated with commercial launch
vehicles, risks associated with a thrust reverser contract and certain
commercial contracts, and the growing uncertainty in the defense electronics
business. Senior management also reviewed with the Lockheed Board certain issues
relating to Lockheed, which were discussed with Martin Marietta, including but
not limited to the uncertainties relating to production of the C-130, F-22,
Trident and MILSTAR, the growing likelihood of declining facility utilization,
the financial outlook for certain subsidiaries and divisions and the status of
environmental and discontinued operations costs relating to Lockheed's Burbank
facility. Outside legal counsel reviewed with the Lockheed Board the status of
the negotiations with Martin Marietta and the provisions of the proposed
Reorganization Agreement, including but not limited to the negotiations with
respect to the termination provisions provided in the proposed Reorganization
Agreement. Morgan Stanley reviewed the financial analysis and valuation it
conducted with respect to the proposed business combination. On the basis of
these and other analyses, Morgan Stanley delivered their oral opinion, confirmed
later by a written opinion, that as of August 29, 1994, the exchange ratio of
Lockheed Martin Common Stock for Lockheed Common Stock as set forth in the
Reorganization Agreement was fair from a financial point of view to the holders
of Lockheed Common Stock. See "-- Fairness Opinions." After extended discussion,
the Lockheed Board unanimously approved the Reorganization Agreement and the
transactions contemplated thereby. The Lockheed Board also amended the Lockheed
Rights Agreement, dated December 8, 1986, between Lockheed and First Interstate
Bank, Ltd., as rights agent, as amended to date (the "Lockheed Rights
Agreement"), to provide that the Combination will not be an event that triggers
the exercisability of rights under the Lockheed Rights Agreement.
 
     At the conclusion of the Lockheed Board meeting, representatives of
Lockheed and Martin Marietta met to finalize and execute the Reorganization
Agreement.
 
     On February 7, 1995, Lockheed, Martin Marietta and Lockheed Martin amended
the Reorganization Agreement to (i) extend from February 15 to March 31, 1995,
the date after which either Lockheed or Martin Marietta may terminate the
Reorganization Agreement if the Combination has not yet been consummated and
(ii) make the changes described below under the heading "-- Certain Litigation".
 
RECOMMENDATION OF LOCKHEED BOARD; LOCKHEED'S REASONS FOR THE COMBINATION
 
     THE LOCKHEED BOARD, BY UNANIMOUS VOTE, HAS DETERMINED THAT THE COMBINATION
IS IN THE BEST INTERESTS OF THE HOLDERS OF LOCKHEED COMMON STOCK AND RECOMMENDS
THAT HOLDERS OF LOCKHEED COMMON STOCK VOTE FOR THE COMBINATION PROPOSAL.
 
     The Lockheed Board believes the Combination offers Lockheed and its
stockholders a unique opportunity to create a leading aerospace company which
can provide the critical mass and economies of scale necessary to compete
effectively in the current global business environment. The Lockheed Board
believes that the Combination offers, among other things, opportunities for
improved efficiencies, to preserve critical elements of the national defense
industrial base of Lockheed and Martin Marietta, to expand access to commercial,
civil and international markets for the combined business and to broaden the
platform on which to grow. The combined business will have a capital structure
with limited leverage and increased cash flow potential which should offer the
combined business the flexibility to pursue future opportunities.
 
                                       24
<PAGE>   30
 
     The decision of the Lockheed Board to approve the Reorganization Agreement
and to recommend approval of the Combination by the holders of Lockheed Common
Stock was based upon a number of factors, including without limitation, the
following:
 
          (i) the Lockheed Board's understanding of the present and anticipated
     environment in the aerospace/defense industry, the strategic options
     available to Lockheed and the potential for further consolidation within
     the industry which could adversely affect Lockheed's competitive position;
 
          (ii) the Lockheed Board's consideration of, among other things,
     information concerning the financial condition, results of operations,
     prospects and businesses of Lockheed and Martin Marietta, including
     internal financial forecasts of future operating results including
     anticipated revenues and net income for Lockheed through 1998 prepared by
     the management of Lockheed which showed some substantial increases during
     certain years over that time period (however keeping in mind the inherent
     uncertainties of such forecasts, especially in the later years);
 
          (iii) the Lockheed Board's consideration of, among other things,
     current industry, economic and market conditions;
 
          (iv) the Lockheed Board's consideration of, among other things,
     information concerning financial and business prospects for the combined
     business, including possible synergies and consolidations;
 
          (v) the Lockheed Board's understanding that the Combination should
     reduce dependence on any single program and the associated risks of program
     cancellation;
 
          (vi) the Lockheed Board's consideration of financial information
     indicating that the proposed exchange ratio of Lockheed Martin Common Stock
     for Lockheed Common Stock would not result in a near term dilution of
     earnings per share (before any restructuring charges) on an equivalent
     share basis to the stockholders of Lockheed and that the financial
     projections for the combined business would appear to support a dividend
     rate not less than the present equivalent dividend rate on Lockheed Common
     Stock;
 
          (vii) the Lockheed Board's understanding that the Combination could be
     accomplished without additional leverage; its understanding, based upon the
     opinion of its outside legal counsel, that the Combination is structured as
     a "merger of equals" and could be accomplished on a tax-free basis; and its
     understanding, after consultation with its outside auditors, that the
     Combination would be accounted for as a pooling of interests transaction;
 
          (viii) the Lockheed Board's review of presentations from, and
     discussions with, senior executives of Lockheed, representatives of its
     outside legal counsel and representatives of Morgan Stanley regarding the
     business, financial, accounting and legal due diligence with respect to
     Martin Marietta and the terms and conditions of the Reorganization
     Agreement; and
 
          (ix) the Lockheed Board's receipt of an opinion from Morgan Stanley
     that the exchange ratio of Lockheed Martin Common Stock for Lockheed Common
     Stock, as of August 29, 1994 and as of the date of this Joint Proxy
     Statement/Prospectus, is fair from a financial point of view to the holders
     of Lockheed Common Stock.
 
     The Lockheed Board did not assign relative weights to the factors discussed
above.
 
RECOMMENDATION OF MARTIN MARIETTA BOARD; MARTIN MARIETTA'S REASONS FOR THE
COMBINATION
 
     THE MARTIN MARIETTA BOARD, BY UNANIMOUS VOTE, HAS DETERMINED THAT THE
COMBINATION IS IN THE BEST INTERESTS OF THE STOCKHOLDERS OF MARTIN MARIETTA AND
RECOMMENDS THAT THE STOCKHOLDERS OF MARTIN MARIETTA VOTE FOR THE COMBINATION
PROPOSAL.
 
     The Martin Marietta Board believes that Lockheed Martin will be
strategically positioned in the aerospace industry, with competitive positions
across broad market segments. The Martin Marietta Board also believes that the
Combination will provide important economies of scale that will allow Lockheed
Martin to make its products and services more competitive across a wide range of
commercial, civil, defense and
 
                                       25
<PAGE>   31
 
international markets, which the Martin Marietta Board believes is particularly
important in a period of industry consolidation. The Martin Marietta Board also
believes that the combined entity will present enhanced opportunities to
continue to build stockholder value.
 
     In reaching its determination to recommend approval of the Combination, the
Martin Marietta Board considered the factors set forth below:
 
          (i) the continuing decline of the U.S. defense budget over the last
     several years and the expectation of further, albeit more gradual,
     declines;
 
          (ii) the belief that shrinkage in the defense market necessitates a
     consolidation of industry participants;
 
          (iii) the belief that the Combination will allow Lockheed Martin to
     improve operating efficiency, rationalize expenditures and reduce costs,
     thus increasing competitiveness;
 
          (iv) the fact that the Combination will result in Lockheed Martin
     holding competitive positions in key segments of the aerospace industry and
     will strengthen its prospects in commercial, civil, and international
     markets;
 
          (v) the belief that Lockheed Martin will have a more balanced risk
     profile, financially and competitively, than either Lockheed or Martin
     Marietta separately;
 
          (vi) the terms and conditions of the Reorganization Agreement,
     including the exchange ratios of Lockheed Martin Common Stock for Lockheed
     Common Stock and Martin Marietta Common Stock, and the exchange ratio of
     Lockheed Martin Series A Preferred Stock for Martin Marietta Series A
     Preferred Stock, which were considered to be fair in light of the financial
     conditions, businesses, prospects and stock trading histories of Lockheed
     and Martin Marietta;
 
          (vii) the structure of the Combination as a "merger of equals";
 
          (viii) the fact that the Combination will be accomplished without
     additional borrowings;
 
          (ix) the fact that the Combination is expected to be accomplished on a
     tax-free basis and to be accounted for as a pooling of interests
     transaction;
 
          (x) the perception that the management teams would complement each
     other and work well together; and
 
          (xi) the opinion of Bear Stearns that the terms of the Combination are
     fair from a financial point of view to the stockholders of Martin Marietta.
 
     In reaching its conclusion the Martin Marietta Board considered these
factors as a whole and did not attempt to assign relative weights to specific
factors. In addition, the Martin Marietta Board concluded that the U.S.
Department of State's policy to deny defense-related export privileges to the
Lockheed division referred to above would not be likely to materially limit
Lockheed Martin's potential ability to compete in international markets. See
"RECENT DEVELOPMENTS -- Lockheed Plea Agreement."
 
FAIRNESS OPINIONS
 
  Opinion of Lockheed's Financial Advisor
 
     Lockheed retained Morgan Stanley to act as financial advisor in connection
with the Combination. Morgan Stanley was selected by the Lockheed Board to act
as Lockheed's financial advisor based on Morgan Stanley's qualifications,
expertise and reputation, as well as Morgan Stanley's investment banking
relationship and familiarity with Lockheed. No limitations were imposed by the
Lockheed Board upon Morgan Stanley with respect to the investigations made
(except with respect to government classified programs) or the procedures
followed by it in rendering its fairness opinion. Morgan Stanley was not
requested to solicit, and did not solicit, indications of interest from any
party with respect to a business combination with Lockheed.

     Morgan Stanley has rendered to the Lockheed Board its written opinion dated
August 29, 1994 (the "Morgan Stanley August Opinion") that, based upon and
subject to the various considerations set forth in the opinion, on August 29,
1994, the exchange ratio of Lockheed Martin Common Stock for Lockheed Common
Stock reflected in the Reorganization Agreement (the "Lockheed Exchange Ratio")
was fair from a financial point of view to the holders of shares of Lockheed
Common Stock. Morgan Stanley has updated its written opinion as of the date of
this Joint Proxy Statement/Prospectus (the "Morgan Stanley Update Opinion"). The
Lockheed Exchange Ratio was determined by negotiation between Lockheed and
Martin Marietta with advice from Morgan Stanley and Bear Stearns, respectively.
 
     The full text of the Morgan Stanley Update Opinion, which sets forth
assumptions made, matters considered and limitations on the review undertaken,
is attached as Appendix II to this Joint Proxy Statement/Prospectus. Lockheed
stockholders are urged to read the opinion carefully and in its entirety in
conjunction with this Joint Proxy Statement/Prospectus. Morgan Stanley's opinion
addresses only the fairness of the Lockheed Exchange Ratio from a financial
point of view and does not constitute a recommendation to any stockholder of
Lockheed as to how such stockholder should vote on the Combination Proposal. The
summary of the opinion of Morgan Stanley set forth in this Joint Proxy
Statement/Prospectus is qualified in its entirety by reference to the full text
of such opinion.
 
     In rendering both the Morgan Stanley August Opinion and the Morgan Stanley
Update Opinion, Morgan Stanley, among other things: (i) analyzed certain
publicly available financial statements and other information of Lockheed and
Martin Marietta; (ii) analyzed certain internal financial statements and other
financial and operating data concerning Martin Marietta prepared by the
management of Martin Marietta; (iii) analyzed certain financial projections
prepared by the management of Martin Marietta; (iv) discussed the past and
current operations and financial condition and the prospects of Martin Marietta
with senior executives of Martin Marietta; (v) analyzed certain internal
financial statements and other financial and operating data concerning Lockheed
prepared by the management of Lockheed (including interim financial statements
on a company-wide and a divisional basis); (vi) analyzed certain financial
projections (including the budgets for Lockheed and its divisions for 1994 and
1995) prepared by the management of Lockheed; (vii) discussed the past and
current operations and financial condition and the prospects of Lockheed with
senior executives of Lockheed, and analyzed the pro forma impact of the
Combination on Lockheed's earnings per share and consolidated capitalization;
(viii) reviewed the reported prices and trading activity for the Lockheed Common
Stock and the Martin Marietta Common Stock, respectively; (ix) discussed with
the senior management of Lockheed their view of the strategic rationale for the
Combination and the benefits of the Combination to Lockheed and to the holders
of shares of Lockheed Common Stock; (x) compared the financial performance of
Lockheed and Martin Marietta and the prices and trading activity of the Lockheed
Common Stock and the Martin Marietta Common Stock with that of certain other
comparable publicly traded companies and their securities; (xi) reviewed the
financial terms, to the extent publicly available, of certain comparable merger
transactions; (xii) participated in discussions and negotiations among
representatives of Lockheed and Martin Marietta and their respective financial
and legal advisors; (xiii) reviewed the Reorganization Agreement; (xiv) reviewed
the agreements described below (under "OWNERSHIP OF LOCKHEED, MARTIN MARIETTA
AND LOCKHEED MARTIN -- Martin Marietta") between Martin Marietta and GE; (xv) in
the case of the Morgan Stanley Update Opinion, reviewed the Joint Proxy
Statement/Prospectus in substantially the final form to be sent to the
stockholders of Lockheed; and (xvi) performed such other analyses as Morgan
Stanley deemed appropriate, including analyzing quantitative and qualitative
business information supplied to it by the management of Lockheed concerning
strategic benefits of the Combination (which benefits are discussed above under
"-- Recommendation of Lockheed Board; Lockheed's Reasons for the Combination").
 
     Morgan Stanley assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by it for purposes of
rendering its opinion. With regard to the financial projections referred to in
clauses (iii) and (vi) of the preceding paragraph, Morgan Stanley assumed that
they were reasonably prepared on bases reflecting the best currently available
estimates of the future financial performance of Lockheed and Martin Marietta.
Morgan Stanley did not make any independent valuation or appraisal of the assets
or liabilities of Lockheed or Martin Marietta, nor was it furnished with any
such appraisals. Morgan Stanley assumed that the Combination would be accounted
for as a pooling of interests
 
                                       27
<PAGE>   33
 
business combination under the requirements of APB No. 16 and would be
consummated in accordance with the terms set forth in the Reorganization
Agreement. Each of Morgan Stanley's opinions states that it is necessarily based
on economic, market and other conditions as in effect on, and the information
made available to Morgan Stanley as of, the date of such opinion.
 
     The following is a brief summary of Morgan Stanley's presentation to the
Lockheed Board on August 20, 1994.
 
     Comparative Stock Price Performance. As part of its analysis, Morgan
Stanley reviewed the recent stock market performance of Lockheed and Martin
Marietta and compared such performance to that of a group of other companies in
the defense industry which was comprised of Northrop Corporation (now Northrop
Grumman Corporation), McDonnell Douglas Corporation, Loral Corporation, Raytheon
Company, E-Systems, Inc., TRW Inc., Rockwell International Corporation and The
Boeing Company. Morgan Stanley also reviewed the ratios of Lockheed's to Martin
Marietta's stock prices over various periods ending August 18, 1994, and
computed the premium or discount of the Lockheed Exchange Ratio in relation to
the aforementioned ratios. The ratios of closing stock prices of Lockheed to
Martin Marietta for the various periods ending August 18, 1994, were as follows:
1.609 for the previous five years; 1.597 for the previous three years; 1.567 for
the previous two years; 1.484 for the previous twelve months; 1.438 for the
previous six months; 1.444 for the previous three months; 1.380 for the previous
thirty days; 1.309 for August 18, 1994; and with respect to the low and high
ratios for the previous year, 1.309 and 1.726, respectively.
 
     Morgan Stanley observed that the Lockheed Exchange Ratio represented a
premium of approximately 1.3%, 2.1%, 4.0%, 9.8%, 13.4%, 12.9%, 18.1%, 24.5% and
24.5% and a discount of 5.6%, respectively, over the aforementioned ratios of
Lockheed to Martin Marietta stock prices.
 
     Contribution Analysis. Morgan Stanley analyzed the pro forma equity
contribution of each of Lockheed and Martin Marietta to the combined company if
the Combination was to be consummated. Such analysis was based on Morgan
Stanley's research analysts' estimates of 1994 and 1995 earnings before interest
and taxes ("EBIT"), net income before preferred stock dividends and free cash
flow (defined as net income before preferred stock dividends plus depreciation
and amortization minus capital expenditures) for Lockheed and Martin Marietta,
respectively. The estimates of Morgan Stanley's research analysts were generated
independently of, but were substantially consistent with, management's financial
projections referred to above. Such analysis showed that, for fiscal 1994,
Lockheed's contribution to the combined company's EBIT, net income before
preferred stock dividends and free cash flow, would result in an implied
ownership for Lockheed stockholders of approximately 43.9%, 45.3% and 46.4%,
respectively. For fiscal year 1995, such equity ownership would be approximately
equal to 42.4%, 44.7% and 45.8%, respectively. These contribution percentages
were computed before taking into account any synergies or cost savings that may
be realized if the Combination were to be consummated. These figures compared to
Lockheed stockholders' pro forma ownership in the combined company, pursuant to
the Combination, of 45.1% on a fully diluted basis (which assumes conversion of
the Martin Marietta Series A Preferred Stock), using the treasury stock method.
Morgan Stanley observed that the contribution analysis did not take into account
the different valuation multiples, such as the price-earnings multiples, that
the market ascribed to Lockheed and Martin Marietta. Morgan Stanley also
observed that Martin Marietta's 1994 and 1995 price-earnings multiples, based on
research analysts' estimates, were currently higher than Lockheed's
corresponding price-earnings multiples.
 
     Pro Forma Analysis of the Combination. Morgan Stanley analyzed certain pro
forma effects of the Combination on the earnings and capitalization of the
combined company, as well as Lockheed's earnings per share, after taking into
account the Lockheed Exchange Ratio. These analyses were based on Morgan
Stanley's research analysts' estimates of 1994 and 1995 net income for Lockheed
and Martin Marietta, respectively. Based on such analysis, Morgan Stanley
observed that the Combination would result in a slight decrease in Lockheed's
earnings per share in 1994 and a slight increase in Lockheed's earnings per
share in 1995. Morgan Stanley did not attempt to identify or quantify synergies
(through, for example, cost reductions and rationalizations, as described below)
which might be achieved in connection with the Combination. However, for
illustrative purposes, and as a hypothetical example, Morgan Stanley also
analyzed certain pro forma effects of the Combination on the earnings of the
combined company, as well as Lockheed's earnings
 
                                       28
<PAGE>   34
 
per share, assuming that $200 million in pre-tax synergies would be realized in
each of 1994 and 1995 in connection with the Combination. While a level of
synergy can be expected to be achieved in a strategic business combination such
as the Combination as a result of rationalization (through elimination of
duplicate facilities and more efficient utilization of capacity, including
research and development expenditures, manufacturing, sales and distribution
capacity) and cost reductions (including savings realized through economies of
scale), the $200 million pretax amount was arbitrarily selected by Morgan
Stanley without any investigation or as a result of any analysis, in order to
ascertain the arithmetic sensitivity of post-Combination earnings to the
achievement of synergies, and Morgan Stanley expressed no view as to whether
these synergies would be obtained, or the amount or timing of such synergies. No
assurances can be given that the hypothetical amount of these synergies bears
any relation to the synergies, if any, which might be realized as a result of
the Combination. Based on such illustrative analysis, Morgan Stanley observed
that, after taking into account such hypothetical synergies, the Combination
would result in an increase in Lockheed's earnings per share in fiscal 1994 and
1995 of 12.2% and 12.8%, respectively.
 
     Pro Forma Share Price Analysis. Morgan Stanley performed an analysis of
Lockheed's potential share price assuming the Combination were to be
consummated. Based on hypothetical multiples of 1995 net income for the combined
company, ranging from Lockheed's current multiple of estimated 1995 earnings to
Martin Marietta's current multiple of estimated 1995 earnings, and based on
Morgan Stanley's research analysts' estimates of 1995 net income for Lockheed
and Martin Marietta, respectively, and after giving effect to the Lockheed
Exchange Ratio of 1.63, Morgan Stanley calculated pro forma market values per
share of Lockheed Common Stock ranging from approximately $65 to $79. These
prices compared to Lockheed's market price of $64 per share on August 18, 1994.
For illustrative purposes, Morgan Stanley performed a similar analysis assuming
that $200 million in hypothetical pre-tax synergies would be realized in
connection with the Combination. Morgan Stanley expressed no view as to whether
these synergies would be obtained or the amount or timing of such synergies.
Such analysis resulted in pro forma market values ranging from approximately $72
to $89 per share of Lockheed Common Stock.
 
     The above summary of the presentations by Morgan Stanley to the Lockheed
Board does not purport to be a complete description of such presentations or of
all the advice rendered by Morgan Stanley, including advice with respect to the
structuring of and issues relating to consummation of the Combination. Morgan
Stanley believes that its analyses and the summary set forth above must be
considered as a whole and that selecting portions of its analyses, without
considering all analyses, or of the above summary, without considering all
factors and analyses, could create an incomplete view of the process underlying
the analyses set forth in Morgan Stanley's presentation to the Lockheed Board
and its opinion. In performing its analyses, Morgan Stanley made numerous
assumptions with respect to industry performance, general business and economic
conditions and other matters, many of which are beyond the control of Lockheed
or Martin Marietta. The analyses performed by Morgan Stanley are not necessarily
indicative of actual values or actual future results, which may be significantly
more or less favorable than suggested by such analyses. In addition, analyses
relating to value of businesses do not purport to be appraisals or to reflect
the prices at which businesses actually may be valued in the market place.
 
     Lockheed retained Morgan Stanley based upon its experience and expertise.
Morgan Stanley is an internationally recognized investment banking and advisory
firm. Morgan Stanley, as part of its investment banking business, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. Morgan Stanley makes a market
in Lockheed Common Stock and Martin Marietta Common Stock and may continue to
provide investment banking services to the combined entity in the future. In the
course of its market-making and other trading activities, Morgan Stanley may,
from time to time, have a long or short position in, and buy and sell securities
of, Lockheed and Martin Marietta. Morgan Stanley and its affiliates have, in the
past, provided financial advisory and financing services to Lockheed, including
services rendered in connection with Lockheed's purchase of the Tactical
Military Aircraft business of the General Dynamics Corporation in 1993, and has
received customary fees for the rendering of such services. Morgan Stanley and
its affiliates have also provided financial advisory and financing services to
Martin Marietta, including services rendered in
 
                                       29
<PAGE>   35
 
connection with the initial public offering of a portion of the stock of Martin
Marietta Materials, Inc. in 1994, and has received customary fees for the
rendering of such services.
 
     Pursuant to a letter agreement, dated August 9, 1994, between Lockheed and
Morgan Stanley, Lockheed paid Morgan Stanley a fee of $3.5 million upon
announcement of the proposed Combination and will pay an additional fee of $13.5
million only upon the successful consummation of the Combination. Lockheed has
also agreed to reimburse Morgan Stanley for its out-of-pocket expenses (of which
$171,000 has been billed and paid to date). In addition, Lockheed has agreed to
indemnify Morgan Stanley and its affiliates, their respective directors,
officers, agents and employees and each person, if any, controlling Morgan
Stanley or any of its affiliates against certain liabilities, including
liabilities under federal securities laws, and expenses, related to Morgan
Stanley's engagement.
 
  Opinion of Martin Marietta's Financial Advisor
 
     The Martin Marietta Board selected Bear Stearns as its financial advisor in
connection with the Combination. The Martin Marietta Board selected Bear Stearns
to act as its financial advisor and to render its opinion in connection with the
Combination based on Bear Stearns' qualifications, expertise, and reputation in
providing advice to companies in the aerospace and defense electronics
industries as well as its prior investment banking relationship and familiarity
with Martin Marietta.
 
     Bear Stearns delivered its written opinion to the Martin Marietta Board to
the effect that, as of August 27, 1994 (the "Bear Stearns August Opinion"), the
Combination was fair, from a financial point of view, to the stockholders of
Martin Marietta. Bear Stearns has updated its written opinion to the Martin
Marietta Board as of the date of this Joint Proxy Statement/Prospectus (the
"Bear Stearns Update Opinion").
 
     The full text of the Bear Stearns Update Opinion is attached as Appendix
III to this Joint Proxy Statement/Prospectus. Martin Marietta stockholders are
urged to, and should, read this opinion carefully in its entirety in conjunction
with this Joint Proxy Statement/Prospectus for assumptions made, matters
considered and limits of the review by Bear Stearns. No limitations were imposed
by the Martin Marietta Board upon Bear Stearns with respect to the
investigations made or procedures followed by Bear Stearns in rendering its
opinion, except that Bear Stearns was not provided with information regarding
government classified programs of Martin Marietta or Lockheed. Bear Stearns was
not requested to solicit and did not solicit indications of interest from third
parties with respect to a business combination with Martin Marietta. Bear
Stearns' opinion addresses only the fairness of the Combination from a financial
point of view and does not constitute a recommendation to any stockholder of
Martin Marietta as to how such stockholder should vote on the Combination
Proposal. The summary of the opinion of Bear Stearns set forth in this Joint
Proxy Statement/Prospectus is qualified in its entirety by reference to the full
text of such opinion.
 
     In rendering the Bear Stearns Update Opinion, Bear Stearns, among other
things: (i) reviewed the Joint Proxy Statement/Prospectus in substantially the
final form to be sent to the stockholders of Martin Marietta, (ii) reviewed
Martin Marietta's and Lockheed's Annual Reports to Stockholders and Annual
Reports on Form 10-K for the fiscal years ended December 1990 through 1993, and
Quarterly Reports on Form 10-Q for the fiscal periods ended March, June and
September 1994, (iii) reviewed certain operating and financial information,
including projections, provided by Martin Marietta's and Lockheed's managements
relating to Martin Marietta's and Lockheed's business prospects, including a
business plan prepared by the management of Martin Marietta, which included
estimates regarding revenue, operating profits, and earnings, (iv) had
discussions with certain members of the senior management of Martin Marietta and
Lockheed concerning their respective companies' operations, historical financial
statements and future prospects, and their views of the business, operational
and strategic benefits, potential synergies, cost savings and other implications
of the Combination (including the anticipated reduction of duplicate facilities,
corporate overhead, and excess research and development and manufacturing
capacity and the enhanced ability to operate as a prime contractor with a more
complete product because of the companies' complementary expertise), (v)
reviewed the pro forma financial impact of the Combination on Martin Marietta,
(vi) reviewed the historical stock prices and trading volumes of the Martin
Marietta Common Stock and the Lockheed Common Stock,
 
                                       30
<PAGE>   36
 
(vii) reviewed the publicly available financial information and stock market
performance of other publicly held companies in businesses similar to those of
Martin Marietta and Lockheed, (viii) considered the terms of selected
transactions deemed generally comparable to the Combination and (ix) considered
such other studies, analyses, inquiries and investigations which Bear Stearns
deemed relevant, including quantitative and qualitative business information
supplied to it by the management of Martin Marietta concerning the strategic
benefits of the Combination.
 
     Bear Stearns relied upon and assumed without independent verification the
accuracy and completeness of all of the financial and other information provided
to it for purposes of its opinion. In addition, Bear Stearns did not make or
seek to obtain appraisals of Martin Marietta's or Lockheed's assets and
liabilities in rendering its opinion. Bear Stearns further relied upon the
assurances of the managements of Martin Marietta and Lockheed that the
managements were not aware of any facts that would make the information provided
to Bear Stearns incomplete or misleading. Bear Stearns' opinion is necessarily
based upon the economic, market and other conditions as in effect on, and the
information made available to it as of, the date of its opinion. Bear Stearns
further assumed that the Combination would be accounted for in accordance with
the pooling of interests method of accounting under the requirements of APB No.
16.
 
     The following is a brief summary of certain of the financial analyses used
by Bear Stearns in connection with providing its opinions to the Martin Marietta
Board.
 
     Contribution Analysis. Bear Stearns analyzed the pro forma contribution of
each of Martin Marietta and Lockheed to the combined entity, if the Combination
were to be consummated, and reviewed certain historical and estimated future
operating and financial information including, among other things, the revenue,
operating cash flow, operating income and net income of Martin Marietta and
Lockheed, and the pro forma revenue, operating cash flow, operating income and
net income of the combined entity resulting from the Combination based on
internal financial analyses and forecasts for Martin Marietta and Lockheed
prepared by their respective managements. Such analysis did not take into
account any potential synergies or cost savings that might be realized after the
Combination. Such analysis indicated that, based on management forecasts, for
1994 Martin Marietta would contribute to pro forma (i) sales, (ii) operating
cash flow, (iii) operating income and (iv) net income of the combined entity
resulting from the Combination the respective amounts of (i) 42.5%, (ii) 53.8%,
(iii) 57.5% and (iv) 56.2%, with similar estimated respective amounts for 1995
being (i) 43.0%, (ii) 51.3%, (iii) 55.0% and (iv) 52.3%. Bear Stearns observed
that such amounts compared favorably with the approximately 54.8% of the pro
forma fully diluted number of shares for the combined entity to be owned by
former Martin Marietta common and preferred stockholders after the Combination.
Bear Stearns noted that the contribution analysis did not consider the different
valuation multiples, such as the price-earnings multiples, that the market
ascribed to Martin Marietta and Lockheed both on a current basis and on a
historical basis.
 
     Historical Stock Trading Analysis. Bear Stearns reviewed the historical
public trading prices of Martin Marietta Common Stock and of Lockheed Common
Stock for the five years ended August 26, 1994. Bear Stearns also reviewed both
the historical ratio of the public trading price per share of Martin Marietta
Common Stock to the public trading price per share of Lockheed Common Stock on a
quarterly basis from January 6, 1989 through and including August 26, 1994 as
well as the average public trading prices of Lockheed Common Stock and Martin
Marietta Common Stock over periods ranging from the 5 to the 180 days
immediately preceding August 26, 1994. Such analysis indicated that the ratio of
the average public trading price per share of Lockheed Common Stock to the
average public trading price per share of Martin Marietta Common Stock ranged
from 1.45 for the 180 days preceding August 26, 1994 to 1.32 for the 5 days
preceding August 26, 1994. From the week ended June 17, 1994 to the week ended
August 26, 1994, the ratio of the closing price of Lockheed Common Stock at the
end of each week to the closing price of Martin Marietta Common Stock at the end
of each week ranged from 1.52 to 1.35. Over the 12 month period ended August 26,
1994, the ratio of public trading prices of Lockheed Common Stock to Martin
Marietta Common Stock ranged from a high of 1.73 to a low of 1.31. Such amounts
were compared to the Lockheed Exchange Ratio of 1.63.
 
                                       31
<PAGE>   37
 
     Pro Forma Combination Analysis. Bear Stearns analyzed earnings per share
estimates for 1995, 1996 and 1997 for both Martin Marietta and, on a pro forma
basis, for the combined entity after the Combination. These analyses were based
upon projections provided by the managements of Martin Marietta and Lockheed and
consensus research analysts' estimates. Such analysis did not take into account
any potential synergies or cost savings that might be realized after the
Combination. Based on managements' projections, such analysis showed accretion
(dilution) in the fully diluted earnings per share resulting from the
Combination of 0.0%, (3.9%) and 10.3% for the years 1995, 1996 and 1997,
respectively.
 
     Imputed Equity Valuation Analysis. Bear Stearns derived a range of values
(i.e., a "reference range") to compare the equity value per fully-diluted share
of Martin Marietta Common Stock to the equity value per fully-diluted share of
the combined entity after the Combination, in order to analyze the fairness of
the Combination to the stockholders of Martin Marietta from a financial point of
view. The reference range of values was based on (i) a discounted cash flow
analysis, (ii) an analysis of selected comparable companies in the aerospace and
defense electronics industries and (iii) an analysis of selected transactions.
Selected actual and estimated financial, operating and stock market information
was analyzed for: Martin Marietta and Lockheed; selected aerospace companies
(i.e., Boeing, McDonnell Douglas, Northrop/Grumman and Rockwell); and selected
defense electronics companies (i.e., E-Systems, General Motors Class H Stock --
GM Hughes Electronics Corporation, Litton Industries Inc., Loral and Raytheon).
Bear Stearns observed that no company used in the above analysis as a comparison
is identical to Martin Marietta, Lockheed or the combined entity. The reference
range of values was also based, among other factors, on certain other analyses
performed by Bear Stearns, including an analysis of selected transactions
involving acquisitions of companies in the aerospace and/or defense electronics
business (i.e., Northrop/Grumman, Loral/IBM Federal Systems, Lockheed/General
Dynamics-Ft. Worth and Martin Marietta/GE Aerospace). In reviewing these
transactions, Bear Stearns noted that such transactions differed from the
Combination in that they involved a change of control of a public company or the
purchase of the assets of a division; none of these transactions involved a
"merger of equals" of public companies.
 
     Based upon a reference range of values for Martin Marietta of $7.5 billion
to $9.0 billion and after making certain adjustments related to, among other
things, the debt outstanding, Bear Stearns derived an imputed equity value per
share for Martin Marietta ranging from $47.04 to $58.69, based upon the fully
diluted number of shares. Based upon a reference range of values for the
combined entity after the Combination of $14.5 billion to $18.0 billion, and
after making certain adjustments described below, Bear Stearns derived an
imputed equity value per fully diluted share for the combined entity after the
Combination ranging from $50.81 to $65.65, which compares favorably to the
closing per share price of Martin Marietta Common Stock of $48.25 on August 26,
1994. These adjustments related to, among other things, the debt outstanding.
The adjustments also considered, for analytical purposes, the effect of (y) an
estimated $175.0 million per year in certain potential pre-tax cost savings and
other synergies which may arise from the Combination less (z) a one time $300.0
million estimated after-tax cash cost arising from the Combination inclusive of,
among other things, severance costs. These adjustments were based on amounts
estimated by the management of Martin Marietta and assumptions independently
made by Bear Stearns as to the amount and timing of cost savings and other
synergies that could be realized by the combined entity after the Combination
and the uncertainties associated with such estimates. Bear Stearns expressed no
view on when or whether the aforementioned cost savings or synergies could be
obtained. No assurances can be given that cost savings and synergies, if any, in
the amount estimated will be realized as a result of the Combination.
 
     Other Analyses. Bear Stearns conducted such other analyses as it deemed
necessary including the review of selected investment research reports on, and
earnings estimates for, Martin Marietta and Lockheed and the analysis of
available information regarding the stock ownership of Martin Marietta and
Lockheed.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analysis as a whole, could create an incomplete view of the processes
underlying Bear Stearns' opinion. In arriving at its opinion, Bear Stearns
considered the results of all such analyses. The analyses were prepared solely
for purposes of providing its opinion as to the fairness of the Combination to
Martin Marietta and do not purport to be appraisals or necessarily reflect the
prices at which businesses or securities actually
 
                                       32
<PAGE>   38
 
may be sold. Analyses based upon forecasts of future results are not necessarily
indicative of actual future results, which may be significantly more or less
favorable than suggested by such analyses. As described above, Bear Stearns'
opinion and presentation to the Martin Marietta Board was one of many factors
taken into consideration by the Martin Marietta Board in making its
determination to approve the Reorganization Agreement. The foregoing summary
does not purport to be a complete description of the analysis performed by Bear
Stearns.
 
     Bear Stearns is an internationally recognized investment banking firm and
is continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions and other purposes. Bear Stearns
recently advised Martin Marietta in its offer to purchase the Grumman
Corporation.
 
     In the ordinary course of its business, Bear Stearns may actively trade the
equity securities of Martin Marietta and Lockheed for its own account and for
the accounts of customers and, accordingly, may, at any time, hold a long or
short position in such securities.
 
     Pursuant to a letter agreement, dated August 23, 1994, Martin Marietta has
paid Bear Stearns a fee of $3.5 million for rendering its opinion in conjunction
with the Combination and will pay an additional fee of $13.5 million only upon
completion of the Combination. Martin Marietta has also agreed to reimburse Bear
Stearns for its reasonable out-of-pocket expenses (which have not yet been
billed), including the reasonable fees and disbursements of counsel, and to
indemnify Bear Stearns and certain related persons against certain liabilities
in connection with the engagement of Bear Stearns, including certain liabilities
under the federal securities laws. Bear Stearns, from time to time, has also
rendered investment banking and other financial advisory services to Martin
Marietta, for which it received customary fees in conjunction with these
services. Bear Stearns has also provided advice to Martin Marietta with regard
to the stockholder rights plan adopted at the time of the announcement of the
proposed Combination, for which no additional fee will be paid.
 
INTERESTS OF CERTAIN PERSONS IN THE COMBINATION
 
  Lockheed
 
     Termination Benefits Agreements. In 1991, Lockheed entered into revised
severance agreements (the "Termination Benefits Agreements") with 23 of the
current Board-elected executive officers, including members of senior
management. From January 1992 through March 1994, Lockheed entered into 14
additional Termination Benefit Agreements with certain executive officers when
they were elected by the Lockheed Board. The Termination Benefits Agreements
provide for the payment of certain benefits described below if, within three
years after the occurrence of certain events with respect to Lockheed (which are
defined in the Termination Benefits Agreements and would include the Pacific Sub
Merger), the covered executive officer either (a) is terminated by Lockheed
(other than on account of death, disability or retirement of the officer or for
"cause," defined in the Termination Benefits Agreements to include, among other
things, willful and continued failure to substantially perform his or her
duties, or willful misfeasance or gross negligence related to his or her
employment) or (b) terminates his or her employment with Lockheed for "good
reason" (as defined in the Termination Benefits Agreements to include, among
other things, a reduction in base salary, bonus or certain other benefits,
certain changes in status, duties or position with Lockheed or geographic
relocation).
 
     Lockheed's Termination Benefits Agreements generally provide for a lump sum
cash payment (the "Lump Sum Payment") equal to the sum of the following amounts:
two times the officer's base annual salary at the time of the triggering event
or termination, two times an amount determined by multiplying the officer's base
salary by the average percentage of awards under the Lockheed Management
Incentive Compensation Plan to base salary paid during the last two years, and
the cash value of the officer's contingent award established under the Lockheed
Long Term Performance Plan for each incomplete performance cycle as of the date
of termination, calculated on the basis that all performance goals were fully
attained and such performance cycles were completed in their entirety. The
Termination Benefits Agreements also provide for a payment equal to the value of
certain health and dental insurance plans and other fringe benefits as in effect
prior to the change in control for a two-year period following termination.
Additional benefits provided by the Termination Benefits Agreements include the
vesting of all retirement benefits and the addition of two years of
 
                                       33
<PAGE>   39
 
credited service under Lockheed's salaried retirement plans and the entitlement
to two additional years of matching contributions under Lockheed's savings
plans. If the officer attains age 65 within two years of termination of
employment, certain benefits under the Termination Benefits Agreement will be
pro-rated accordingly. If the officer obtains other employment, the Lump Sum
Payment received on termination may be reduced if compensation received from the
new employer exceeds fifty percent of the annualized salary and bonus included
in the Lump Sum Payment, provided that in no event will the Lump Sum Payment be
reduced to an amount less than one year's annual compensation. Benefits under
the Termination Benefits Agreements may be subject to an excise tax payable by
the officer, and may not be deductible by Lockheed, to the extent they exceed
certain statutory limitations.
 
     Each of the Termination Benefits Agreements continues in effect through the
end of the calendar year and is automatically extended on each January 1
thereafter for an additional year unless Lockheed gives the officer advance
notice to the contrary. Stockholder approval of the Combination will trigger an
automatic extension of the Termination Benefits Agreements to a date 36 months
after such approval.
 
     The severance policy of Lockheed with respect to executive officers as
reflected in the Termination Benefit Agreements was approved by an advisory vote
of the stockholders of Lockheed in April 1991.
 
     Employee Stock Option Programs. Under the Reorganization Agreement, stock
options outstanding under the stock option plans maintained by Lockheed will be
converted to options to acquire Lockheed Martin Common Stock as described in
greater detail below under "THE REORGANIZATION AGREEMENT -- Certain Benefits
Matters." Under the terms of the option agreements executed pursuant to
Lockheed's 1992 Employee Stock Option Program (the "Program"), upon consummation
of the Combination, options granted under the Program and held by persons then
employed by Lockheed or any subsidiary will become exercisable to the full
extent theretofore not exercisable. Based upon options outstanding at December
31, 1994, the exercisability of options to purchase an aggregate of 307,775
shares of Lockheed Common Stock valued at $2.2 million would be accelerated if
the Combination occurs. However, options with respect to 307,025 of these shares
would otherwise vest by the end of February 1996 even if the Combination is not
consummated. Of the options outstanding at December 31, 1994 subject to
acceleration, options to purchase an aggregate of 170,575 shares of Lockheed
Common Stock valued at $1.2 million are held by executive officers of Lockheed,
including options with respect to 7,500 (valued at $52,988); 7,500 (valued at
$52,988); 15,000 (valued at $105,975); 7,000 (valued at $49,455); and 30,000
(valued at $211,950) shares held by Messrs. Cannestra, Coffman, Marafino, Peline
and Tellep, respectively. See "OWNERSHIP OF LOCKHEED, MARTIN MARIETTA AND
LOCKHEED MARTIN -- Lockheed." Messrs. Marafino and Tellep have informed the
Lockheed Board in writing that they intend to voluntarily refrain from
exercising any options that become exercisable upon consummation of the
Combination prior to the date the options would have been exercisable had the
Combination not been consummated. The values set forth above are based on the
difference between the per share exercise price and the closing price of $71 7/8
per share for Lockheed Common Stock on the NYSE Composite Tape on February 1,
1995. See "COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION."
 
     Long Term Performance Plan. Awards under Lockheed's Long Term Performance
Plan are based on the corporation's financial performance over 3-year
performance cycles, beginning in successive years. Performance measurements for
the 1993 cycle and the 1994 cycle are based on Lockheed's absolute percentage
gain in total stockholder value as compared to an absolute target and Lockheed's
investment value relative to a peer group investment value. Lockheed has taken
action to terminate the Long Term Performance Plan effective upon the
consummation of the Combination. Under the terms of the plan, the participants
are entitled to prorated awards for compensation earned up to the Merger Date
for each performance cycle terminated prior to the end of the three year period,
with the awards calculated as if the pre-established targets had been attained.
Lockheed estimates the total prorated payments for the 1993 and 1994 performance
cycles for all participants, assuming consummation of the Combination on March
15, 1995, to be approximately $3.7 million, including payments to Messrs.
Cannestra, Coffman, Marafino, Peline and Tellep of approximately $193,154;
$222,154; $437,077; $169,138 and $555,770, respectively.

     Directors Deferred Compensation. Under a deferred compensation plan of
Lockheed, all or a portion of the cash annual fee and meeting fees payable by
Lockheed to its non-employee directors may be deferred to periods following the
time a participant ceases to be a member of the Lockheed Board. In addition,
$5,000 is paid annually on behalf of each non-employee director to a trust
maintained under the deferred compensation plan for the purpose of purchasing
Lockheed Common Stock on the open market for the benefit of such non-employee
directors. Prior to 1993, directors could also direct a portion of their cash
remuneration to the trust for the purchase of Lockheed Common Stock. Lockheed
Common Stock held by the trust is distributable after a participant ceases to be
a member of the Lockheed Board. Lockheed has amended the deferred compensation
plan so as to continue the deferral of the cash and stock balances of those
members of the Lockheed Board who become members of the Lockheed Martin Board
until after they cease to be members of the Lockheed Martin Board. Lockheed
Common Stock held by the trust would be exchanged for Lockheed Martin Common
Stock upon consummation of the Combination. See "OWNERSHIP OF LOCKHEED, MARTIN
MARIETTA AND LOCKHEED MARTIN -- Lockheed."
 
     Directors Retirement Plan. Non-employee directors of Lockheed who cease to
be members of the Lockheed Board and who have reached age 65 with five or more
years of service on the Lockheed Board are entitled to receive an annual
retirement benefit equal to the amount of the annual fee, including the portion
contributed in trust for the purchase of Lockheed Common Stock, in effect on the
date the director ceases to be a member of the Lockheed Board. Unless a director
elects an equivalent lump sum payment, the benefits are payable monthly to the
retired director or the director's surviving spouse for a period equal to the
number of years (including any partial year), up to twenty, that the director
served on the Lockheed Board. Lockheed has amended the retirement plan so as to
(i) vest all benefits under the plan but not otherwise increase the amount or
duration of the benefits and (ii) make the benefits payable on the later of
leaving the Lockheed Board or the Lockheed Martin Board. Assuming consummation
of the Combination on March 15, 1995, Directors Kirby, Savage, Trost and
Yearley, each with slightly over four years of service, would become entitled to
receive a monthly benefit of $2,500 for five years, payable as described in
clause (ii) above. Similarly, Directors Cheney and Cook would become entitled to
receive the same benefit for two years and four years, respectively, based on
service of approximately one year and 3 3/4 years, respectively. See "MANAGEMENT
OF LOCKHEED MARTIN -- Directors."
 
     Directors and Officers of Lockheed Martin. Twelve of the current 14
directors of Lockheed will become directors of Lockheed Martin. See "MANAGEMENT
OF LOCKHEED MARTIN -- Directors." In addition, certain executive officers of
Lockheed, including Messrs. Cannestra, Coffman, Marafino and Tellep, will become
officers of Lockheed Martin. See "MANAGEMENT OF LOCKHEED MARTIN -- Officers."
 
  Martin Marietta
 
     Under the terms of various of Martin Marietta's benefit plans, the
Combination (which will constitute a "change of control" as that term is defined
in the governing documents for such plans) will result in (a) the acceleration
of the payment of certain benefits that would otherwise have been payable over
time, (b) the early vesting of certain benefits that would not otherwise be
fully vested as of the Merger Date and (c) in the case of one such plan, the use
of modified formulae for calculating the amounts of such benefits. The Martin
Marietta Board has determined that it will defer certain payments of these
benefits to any individual who may be one of the five most highly compensated
executive officers of Lockheed Martin in the event that payment may prevent
Martin Marietta from deducting such payments for Federal income tax purposes.
 
     Under the Directors Deferred Compensation Plan an eligible director has the
option each year of deferring receipt of all or part of the fees earned as a
director until after termination of service as a director. A director's annual
election is irrevocable and interest is accrued on the amount deferred. Under
the terms of the plan, following consummation of the Combination, further
deferral of amounts earned prior to the Merger Date will not be permitted, and
each participating director will receive a disbursement of the balance of his or
her deferred compensation account as of the Merger Date. The amount of each
director's deferred compensation balance as of January 31, 1995 (including
accrued interest) was as follows: Mr. Byrne, $580,000; Mr. Clark, $561,000; Mr.
Colodny, $32,000; Mr. Hood, $130,000; Mr. Laird, $1,185,000; Mr. Macklin,
$224,000; and General Vessey, $372,000.
 
                                       35
<PAGE>   41
 
     The Post-Retirement Income Maintenance Plan for Directors provides that a
director who at the time of retirement has served as a director for five years
(or such shorter period as may be approved by the Nominating Committee of the
Martin Marietta Board) and who has attained retirement age (which is currently
age 72) will receive for life an annual fee equal to the annual basic retainer
in effect at the time of retirement. A director who retires early after
completing at least five years of service is entitled to receive an annual fee
equal to the annual retainer in effect at the time of retirement for a period
equal to the number of full years served on the Martin Marietta Board.
 
     Under the terms of the plan, as a result of the Combination, rather than
receiving these annual payments, each director will be entitled to receive a
lump sum payment equal to the present value (i.e., discounted value) of his or
her vested plan benefits determined as if he or she had retired from the Martin
Marietta Board on the Merger Date. Years of service will be rounded up to the
nearest whole year. Thus, as a result of the Combination, directors who have not
attained retirement age as of the Merger Date will be treated as if they had
retired early and not be eligible to receive a lifetime retirement benefit.
Pursuant to a recent amendment, any active director over the age of 62 with five
years of service who will not be nominated to the Lockheed Martin Board will
receive a lump sum amount based on the present value (i.e., discounted value) of
the amounts that would be payable over the longer of the following periods: (a)
the director's life expectancy or (b) years of service as a Martin Marietta
Board member. In determining present value, an after-tax discount rate will be
used. The Plan was also recently amended to provide (i) that non-continuous
service will be aggregated for the purpose of satisfying the service requirement
and (ii) that outside directors who are not nominated to the Lockheed Martin
Board will also receive board and committee fees that would have been paid had
the director continued to serve on the Board for the remaining term of election
by Martin Marietta's stockholders. Directors who have been nominated to the
Lockheed Martin Board will receive a lump sum payment based on the plan
provisions prior to these amendments.
 
     In view of the intended operation of the plan in the absence of a change in
control, the Martin Marietta Board has determined to value the benefit for
directors eligible to receive a lifetime benefit on the basis of the cost of an
annuity contract issued by an insurance company providing the same annual
payments on an after-tax basis over the expected life of the director. The cost
of such annuity contracts may differ from the cost of providing lump sum
payments; however, the differences in cost are not material.
 
     Assuming consummation of the Combination on March 1, 1995, the amount
payable under the plan to each eligible director is estimated to be as follows:
Mr. Alexander, $236,000; Mr. Augustine, $291,000; Mr. Byrne, $572,000; Mr.
Clark, $377,000; Mr. Colodny, $243,000; Mr. Everett, $465,000; Mr. Hennessy,
$357,000; Mr. Hurtt, $243,000; Mr. Laird, $427,000; Mr. Murray, $162,000;
General Vessey, $428,000; and Mr. Young, $190,000.
 
     The Directors Charitable Award Plan provides that in the event of the death
of an incumbent director, Martin Marietta will make donations to charities or
other eligible tax-exempt organizations previously recommended by the director
in an aggregate amount of $1 million. Directors are vested under this plan if
(a) they have served for at least five years on the Martin Marietta Board or (b)
their service on the Martin Marietta Board is terminated due to death,
disability or retirement. Under the terms of the plan, upon consummation of the
Combination, incumbent directors with fewer than five years of service on the
Board (Mrs. King and Messrs. Alexander, Bennett, Hood, Macklin, Murphy and
Murray), will become vested under this plan. This plan does not result in any
economic benefit to directors.
 
     Under the Deferred Compensation and Estate Supplement Plan, officers and
senior executive personnel are eligible to receive a benefit after retirement.
Benefit levels are determined by a schedule approved by the Martin Marietta
Board and depend on the position of the executive and years of plan
participation. A participant receives a percentage of the total scheduled
benefit payable based on age at retirement, payable over ten years commencing at
retirement (or, to a participant's estate, if a participant dies while an active
employee). Under the terms of the plan prior to the recent amendment described
below, payment of the total scheduled benefit would be due in full upon
consummation of the Combination. The Martin Marietta Board has recently amended
this plan to limit the payment upon consummation of the Combination to the
present value of the earned benefit as follows: (a) the total scheduled benefit
will be discounted to present value and
 
                                       36
<PAGE>   42
 
(b) each participant will, on the Merger Date, be entitled to receive a percent
(determined by the number of full years up to ten years, rounded up to the
nearest whole year, of plan participation, and ranging from 20% to 100%) of the
amount determined by such present value calculation. Assuming consummation of
the Combination on March 1, 1995, Martin Marietta estimates that benefit amounts
payable under this plan to 20 employee participants would be approximately
$8,200,000, including the following amounts payable to executive officers: Mr.
Augustine, $1,064,000; Mr. Young, $801,000; Mr. Teets, $561,000; Mr. Bennett,
$728,000; and Mr. Menaker, $367,000; and other executive officers, $1,337,000.
 
     The Post-Retirement Death Benefit Plan is a death benefit program covering
20 participants who hold specific positions approved for participation by the
Martin Marietta Board. The plan provides death benefit coverage commencing
immediately upon retirement in amounts ranging from 15 percent (upon retirement
at age 55) to 150 percent (upon retirement at or after age 64) of final
annualized salary, depending upon the age of the participant at retirement.
Benefits are grossed up for income taxes. This plan will be discontinued if the
Combination is consummated. In lieu thereof, a death benefit will be paid
calculated based on the applicable percentage (determined by age at retirement)
and annualized salary at the time of consummation of the Combination. If each
participant could retire on March 1, 1995 and the applicable percentage is
assumed to be 100% for each participant (which is assumed solely for purposes of
this calculation), the death benefits payable to such persons would be
approximately $6,400,000 in the aggregate. If Lockheed Martin should adopt a
death benefit plan covering any of the current participants in the Martin
Marietta plan, the death benefits payable with respect to those Martin Marietta
executives will be the greater of the amounts payable to them pursuant to the
Lockheed Martin plan or the Martin Marietta plan discussed above.
 
     The Reorganization Agreement provides for each stock option and stock
appreciation right outstanding under Martin Marietta and Lockheed stock option
plans to be converted into an option and stock appreciation right with respect
to stock of Lockheed Martin. Such conversion is described in greater detail
below under the heading "THE REORGANIZATION AGREEMENT -- Certain Benefits
Matters." Upon consummation of the Combination, stock options granted in 1992
under Martin Marietta's Amended Omnibus Securities Award Plan that in the
absence of the Combination would become exercisable in July 1995, will become
immediately exercisable. Likewise, stock options granted in 1993 that would
otherwise become exercisable in July 1995 and 1996, will become immediately
exercisable.
 
     Based upon options outstanding as of February 1, 1995 that were granted in
1992 and 1993, the exercisability of options to purchase an aggregate of
1,210,600 shares of Martin Marietta Common Stock, valued at $10,812,000 and held
by 466 persons, would be accelerated if the Combination occurs. Each of the
individuals listed below holds "in-the-money" options granted in 1992 and 1993
which will become exercisable as a result of the Combination with respect to the
following number of shares of Martin Marietta Common Stock and corresponding
aggregate values: Mr. Augustine, 106,800 shares valued at $1,012,200; Mr. Young,
63,400 shares valued at $595,800; Mr. Teets, 23,400 shares valued at $239,900;
Mr. Bennett, 21,000 shares valued at $215,600; and Mr. Menaker, 14,000 shares
valued at $143,800; and for other executive officers, 87,400 shares valued at
$753,300. The aggregate value is based on the difference between the per share
exercise price and the closing price of $44 3/8 per share on the NYSE Composite
Tape on February 1, 1995. See "SUMMARY -- Comparative Per Share Market Price
Information." Mr. Augustine has informed the Martin Marietta Board in writing
that he intends to voluntarily refrain from exercising any options that become
exercisable upon consummation of the Combination prior to the date the options
would have been exercisable had the Combination not been consummated.
 
     Martin Marietta granted options with respect to 1,353,650 shares of Martin
Marietta Common Stock to 659 employees during 1994. These stock options will not
become exercisable as a result of the Combination but will vest in accordance
with their regular schedule.
 
     Some senior executive personnel have received restricted stock awards under
Martin Marietta's stock plans. The executives are entitled to the stock if they
remain with Martin Marietta or an affiliate during the operative period of the
restrictions. Under the 1991 awards, 50% of which vested in July, 1994, the
restrictions associated with the remaining 50% of the award will continue in
accordance with the terms of the award following consummation of the Combination
unless the employee is terminated or gives notice of termination
 
                                       37
<PAGE>   43
 
for good cause (as defined in the award agreement) within two years following
the Merger Date. The 1993 restricted stock awards will vest upon consummation of
the Combination. Assuming a price for the restricted stock of $44 3/8 per share
(the closing price on the NYSE Composite Tape on February 1, 1995), the 1993
restricted stock awards, which totalled 170,000 shares for all 14 recipients,
would be valued at $7,543,800, including the following awards for executive
officers: Mr. Augustine, 32,000 shares, valued at $1,420,000; Mr. Young, 24,000
shares, valued at $1,065,000; Mr. Teets, 12,000 shares, valued at $532,500; Mr.
Bennett, 12,000 shares, valued at $532,500; and Mr. Menaker, 8,000 shares,
valued at $355,000; and other executive officers, 40,000 shares, valued at
$1,775,000.
 
     There were no restricted stock awards granted to executive officers in 1992
or 1994.
 
     The Amended and Restated Long Term Performance Incentive Compensation Plan
maintained by Martin Marietta applies to performance units awarded after 1990.
The plan provides that each vested unit will be exchanged for a cash amount
calculated under a formula which ties the redemption value of the performance
units to any increase in Martin Marietta's earnings per share ("EPS") at the end
of a three-year period over a base value established at the time of grant.
 
     Performance units granted in 1993 ("1993 Units") provide for redemption in
1996 based on the excess of Martin Marietta's 1995 EPS over the base value
established in 1993. Martin Marietta estimates that, in the absence of the
Combination, each 1993 Unit would be valued at approximately $8.00. The 1993
Units provide, however, that, in the event of a transaction such as the
Combination, such Units will immediately and fully vest in their entirety and a
modified formula will apply, which will result in a per Unit value of
approximately $36.50, which in turn will result in payments following
consummation of the Combination to 439 employee participants with an estimated
aggregate value of approximately $42,398,000, including payments to executive
officers as follows: Mr. Augustine, $3,657,500; Mr. Young, $2,194,500; Mr.
Teets, $731,500; Mr. Bennett, $658,400; and Mr. Menaker, $438,900; and other
executive officers, $3,255,175. Mr. Augustine and his wife have established a
charitable gift fund to which payments attributable to the difference between
the $36.50 to be paid per Unit and the approximately $8.00 which would have been
paid in the absence of the Combination will be contributed (net of taxes due
thereon) upon Mr. Augustine's receipt of such payments. Such receipt may be
deferred pursuant to the decision of the Martin Marietta Board, noted above, to
defer certain payments to the five most highly compensated executive officers in
the event that payment may prevent Martin Marietta from deducting such payments
for Federal income tax purposes. Additionally, with respect to all 1993 Units,
no amounts attributable to the difference between the amount paid per Unit and
that which would have been paid in the absence of the Combination will be
charged to the U.S. Government.
 
     In addition, in the absence of the Combination, 1994 performance units
("1994 Units") would be redeemable in 1997 based upon 1996 EPS. If the
Combination is consummated, the 1994 Units will immediately and fully vest in
their entirety and will be redeemed based upon an estimate of 1996 EPS,
discounted to March 1995. This will result in payments following consummation of
the Combination to 475 employee participants that are estimated to be
approximately $9,758,000 in the aggregate, including payments to executive
officers as follows: Mr. Augustine, $771,000; Mr. Young, $463,000; Mr. Teets,
$231,300; Mr. Bennett, $216,000; and Mr. Menaker, $154,200. The remaining
executive officers will receive $709,300 in the aggregate.
 
     If the Combination is consummated, no further performance units will be
awarded under the Amended and Restated Long Term Incentive Compensation Plan. In
addition, since all outstanding units awarded under the plan will immediately
and fully vest in their entirety and become payable upon consummation of the
Combination, no awards will be deemed to be outstanding for purposes of the
Reorganization Agreement. It is anticipated that any subsequent awards of this
type will be made pursuant to the Lockheed Martin Omnibus Plan or any successor
or substitute plan adopted by Lockheed Martin.
 
     Martin Marietta has employment agreements with Messrs. Augustine, Young,
Teets, Bennett and Menaker and six other executive officers. Under these
agreements, following consummation of the Combination, an officer may, for good
cause (as that term is defined in the various agreements) and within two years
after the Merger Date and within six months after the date on which
circumstances constituting good cause
 
                                       38
<PAGE>   44
 
exist, give notice that he or she elects to terminate employment under the
agreement. Upon receipt of such notice, or upon involuntary termination by
Martin Marietta, the agreements require Martin Marietta to pay the officer an
amount equal to three times his or her average annual taxable compensation for
the preceding five years, less one dollar, as well as any other compensation or
benefits due and any amount necessary to compensate the officer for any excise
tax imposed with respect to payments made under the agreement or any other
agreement between the officer and Martin Marietta. Mr. Augustine has voluntarily
waived his rights under his employment agreement as it relates to this
transaction.
 
     Directors and Officers of Lockheed Martin. Twelve of the current 17
directors of Martin Marietta will become directors of Lockheed Martin. See
"MANAGEMENT OF LOCKHEED MARTIN -- Directors." In addition, certain executive
officers of Martin Marietta, including Messrs. Augustine, Young, Teets, Bennett
and Menaker, will become officers of Lockheed Martin. See "MANAGEMENT OF
LOCKHEED MARTIN -- Officers."
 
ACCOUNTING TREATMENT
 
     The Combination is expected to qualify as a pooling of interests for
accounting and financial reporting purposes. Under this accounting method, the
assets and liabilities of Lockheed and Martin Marietta will be carried forward
to Lockheed Martin at their historical recorded bases. Results of operations of
Lockheed Martin will include the results of both Lockheed and Martin Marietta
for the entire fiscal year in which the Combination occurs. The reported balance
sheet amounts and results of operations of the separate corporations for prior
periods will be combined, reclassified and conformed, as appropriate, to reflect
the combined balance sheets and statements of results of operations for the new
corporation. It is a condition to the Combination that Lockheed and Martin
Marietta each receive from Ernst & Young LLP, Lockheed's and Martin Marietta's
independent auditors, a letter dated the Merger Date to the effect that they
concur with the conclusions of Lockheed's and Martin Marietta's managements that
the transactions contemplated by the Reorganization Agreement, if consummated,
will qualify as transactions to be accounted for in accordance with the pooling
of interests method of accounting under the requirements of APB No. 16. See
"UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS."
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a general description of the material Federal income tax
consequences of the Combination (i) to a stockholder of Lockheed whose shares of
Lockheed Common Stock are converted into shares of Lockheed Martin Common Stock
pursuant to the Pacific Sub Merger and (ii) to a stockholder of Martin Marietta
whose shares of Martin Marietta Common Stock are converted into shares of
Lockheed Martin Common Stock or whose shares of Martin Marietta Series A
Preferred Stock are converted into shares of Lockheed Martin Series A Preferred
Stock pursuant to the Atlantic Sub Merger. The discussion does not address all
aspects of Federal income taxation that may be important to particular
stockholders and may not be applicable to stockholders who are not citizens or
residents of the United States or who acquired their Lockheed or Martin Marietta
stock pursuant to the exercise of employee stock options or otherwise as
compensation. The effects of any applicable foreign, state, local or other tax
laws are not addressed. This discussion assumes that Lockheed and Martin
Marietta stockholders hold their respective shares of Lockheed and Martin
Marietta stock as capital assets as defined in the Code. Lockheed and Martin
Marietta stockholders should consult their own tax advisors as to the particular
tax consequences of the Pacific Sub Merger or the Atlantic Sub Merger, as the
case may be, to them.
 
     Neither Lockheed, Martin Marietta or Lockheed Martin intends to seek a
ruling from the Internal Revenue Service (the "Service") with respect to the tax
consequences of the Combination. Lockheed and Martin Marietta believe, based
upon the opinions of O'Melveny & Myers and King & Spalding, respectively, and it
is assumed for purposes of the following discussion, that for Federal income tax
purposes the Combination will constitute tax-free transactions under the Code
and no gain or loss will be recognized (i) by Lockheed or Lockheed stockholders
whose shares of Lockheed Common Stock are converted into shares of Lockheed
Martin Common Stock in the Pacific Sub Merger (except to the extent of cash paid
in lieu of fractional shares) or (ii) by Martin Marietta or by Martin Marietta
stockholders whose shares of Martin
 
                                       39
<PAGE>   45
 
Marietta Common Stock are converted into shares of Lockheed Martin Common Stock
or whose shares of Martin Marietta Series A Preferred Stock are converted into
shares of Lockheed Martin Series A Preferred Stock in the Atlantic Sub Merger.
In rendering such opinions, counsel has relied upon, among other things,
representations contained in certificates of Lockheed and Martin Marietta.
Consummation of each of the Pacific Sub Merger and the Atlantic Sub Merger is
conditioned upon the foregoing opinions of counsel being reconfirmed at the
Merger Date.
 
     The principal Federal income tax consequences of the Pacific Sub Merger to
Lockheed stockholders and the Atlantic Sub Merger to Martin Marietta
stockholders will be as set forth below.
 
     Consequences to Holders of Lockheed Common Stock. Except with respect to
cash received in lieu of fractional shares, no gain or loss will be recognized
by holders of Lockheed Common Stock upon the receipt of Lockheed Martin Common
Stock in the Pacific Sub Merger and the tax basis of the Lockheed Martin Common
Stock received will be equal to the tax basis of the Lockheed Common Stock
surrendered in exchange therefor. For Federal income tax purposes, the holding
period of the Lockheed Martin Common Stock received will include the holding
period of the Lockheed Common Stock surrendered. Based on the Service's advance
rulings policy of treating cash paid in lieu of fractional share interests
arising in corporate reorganizations as having been received by the stockholders
as payment for the fractional share interests redeemed, gains and losses
realized by a stockholder with respect to the receipt of cash in lieu of a
fractional share will be capital gain or loss. To determine the amount of such
gain or loss, a portion of the tax basis in the shares of Lockheed Common Stock
surrendered will be allocated to the fractional share. The amount of such gain
or loss will be the difference between the amount of cash received for such
fractional share and the amount of such basis. In the case of individuals,
long-term capital gains are subject to a maximum tax rate of 28%.
 
     Consequences to Holders of Martin Marietta Common Stock. No gain or loss
will be recognized by holders of Martin Marietta Common Stock upon the receipt
of Lockheed Martin Common Stock in the Atlantic Sub Merger and the tax basis of
the Lockheed Martin Common Stock received will be equal to the tax basis of the
Martin Marietta Common Stock surrendered in exchange therefor. For Federal
income tax purposes, the holding period of the Lockheed Martin Common Stock
received will include the holding period of the Martin Marietta Common Stock
surrendered.
 
     Consequences to the Holder of Martin Marietta Series A Preferred Stock. No
gain or loss will be recognized by the holder of Martin Marietta Series A
Preferred Stock upon receipt of Lockheed Martin Series A Preferred Stock in the
Atlantic Sub Merger. The tax basis of the Lockheed Martin Series A Preferred
Stock received will be equal to the tax basis of the Martin Marietta Series A
Preferred Stock surrendered in exchange therefor. For Federal income tax
purposes, the holding period of Lockheed Martin Series A Preferred Stock
received will include the holding period of the Martin Marietta Series A
Preferred Stock surrendered.
 
     Lockheed Martin. Based upon the opinions of O'Melveny & Myers and King &
Spalding, for Federal income tax purposes Lockheed Martin will recognize no gain
or loss on the issuance of Lockheed Martin Common Stock or Lockheed Martin
Series A Preferred Stock to the Lockheed and Martin Marietta stockholders in the
Pacific Sub Merger and the Atlantic Sub Merger, respectively.
 
     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED HEREIN FOR
GENERAL INFORMATION ONLY. LOCKHEED AND MARTIN MARIETTA STOCKHOLDERS ARE ADVISED
TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE
COMBINATION.
 
REGULATORY APPROVALS
 
     Antitrust. Under the HSR Act and the rules promulgated thereunder by the
FTC, the Combination may not be consummated until notifications have been given
and certain information has been furnished to the FTC and the Antitrust Division
and specified waiting period requirements have been satisfied. Lockheed and
Martin Marietta filed notification and report forms under the HSR Act with the
FTC and the Antitrust
 
                                       40
<PAGE>   46
 
Division effective on September 23, 1994. The FTC, which reviewed the
transaction, made a request for additional information on October 21, 1994. Both
Lockheed and Martin Marietta completed their respective submissions of
additional information on December 22, 1994, and the statutory waiting period
under the HSR Act expired on January 11, 1995.
 
     On December 22, 1994, Lockheed, Martin Marietta, and Lockheed Martin (the
"Companies") executed an Agreement Containing Consent Order with the FTC staff,
which was provisionally accepted by the FTC on January 11, 1995, subject to
further review at the expiration of a public comment period which expires on
March 28, 1995. After the expiration of the public comment period, the FTC will
vote to either finally accept the Consent Order or withdraw its acceptance of
the Consent Order.
 
     With respect to the HSR Act, the Companies may consummate the Combination
at any time subsequent to the January 11, 1995 expiration of the HSR waiting
period and are not required to delay consummation until expiration of the public
comment period and final FTC acceptance. If the Companies consummate the
Combination prior to final FTC acceptance of the Consent Order and the FTC
withdraws its provisional acceptance of the Consent Order, the FTC could file an
administrative action challenging the Combination in whole or in part, and could
seek divestiture of all or part of Lockheed Martin's assets. Any adverse FTC
decision in any such administrative action would be subject to review by a
federal court of appeals. If the FTC withdraws its provisional acceptance of the
Consent Order prior to consummation of the Combination, the FTC could seek a
temporary restraining order and/or a preliminary injunction pursuant to Section
13(b) of the Federal Trade Commission Act to prevent consummation of the
transaction subject to the completion of an administrative action, and any
resulting appeals, adjudicating the lawfulness of the transaction.
 
     The Companies have agreed to comply with the Consent Order during the
public comment period and, if the FTC withdraws its provisional acceptance of
the Consent Order, for ten days thereafter. A summary of the material elements
of the Consent Order is as follows:
 
          (i) The Companies will be prohibited from enforcing or attempting to
     enforce the exclusivity provisions of Lockheed's teaming agreement with GM
     Hughes Electronics Corporation ("Hughes") by which Lockheed and Hughes
     agreed to cooperate to compete for space based early warning satellite
     systems, and the Companies will be prohibited from enforcing or attempting
     to enforce any proprietary rights in the electro-optical sensors developed
     by Hughes for use in such systems in a manner that would inhibit Hughes
     from competing with the Companies. Thus, Hughes will be permitted (but not
     required) to team with other companies or may compete for space based early
     warning satellite systems independently.
 
          (ii) The Companies will be prohibited from enforcing or attempting to
     enforce the exclusivity provisions of Martin Marietta's teaming agreement
     with Northrop Grumman Corporation ("Grumman") by which Martin Marietta and
     Grumman agreed to cooperate to compete for space based early warning
     satellite systems, and the Companies will be prohibited from enforcing or
     attempting to enforce any proprietary rights in the electro-optical sensors
     developed by Grumman for use in such systems in a manner that would inhibit
     Grumman from competing with the Companies. Thus, Grumman will be permitted
     (but not required) to team with other companies or may compete for space
     based early warning satellite systems independently.
 
          (iii) The Companies are required to ensure that no non-public
     proprietary data provided by aircraft manufacturers to Martin Marietta's
     Electronics and Missiles Division ("Electronics and Missiles"), which
     produces LANTIRN night navigation, terrain following and targeting systems
     for aircraft, is disclosed or provided to Lockheed's Aeronautical Systems
     Group, which produces aircraft (except with the prior written consent of
     the proprietor of such data). Electronics and Missiles is required to use
     any such non-public proprietary data only in its capacity as the provider
     of LANTIRN systems.
 
          (iv) The Companies are prohibited from modifying, upgrading or
     otherwise changing LANTIRN systems in any way that discriminates against
     any military aircraft manufacturer with regard to the performance of the
     aircraft or the time or cost required to integrate LANTIRN systems into the
     aircraft
 
                                       41
<PAGE>   47
 
     unless such modifications are necessary to meet competition from other
     products or are approved by the Secretary of Defense or his or her
     designees.
 
          (v) The Companies are required to ensure that no non-public
     proprietary data provided by expendable launch vehicle manufacturers to the
     Companies, when the Companies are acting in their capacities as providers
     of satellites, is disclosed or provided to those portions of the Companies
     that manufacture or sell expendable launch vehicles or is used by the
     Companies otherwise than in their capacities as providers of satellites
     (except with the prior written consent of the proprietor of such data).
 
In addition to the material substantive provisions summarized above, the Consent
Order contains procedural provisions, including a requirement that the Companies
provide a copy of the Consent Order to designated aircraft and expendable launch
vehicle manufacturers from whom they obtain non-public proprietary information,
as well as a requirement that the Companies provide periodic compliance reports
to the FTC. The term of the Consent Order is twenty (20) years.
 
     The Companies do not believe that, if the Combination is consummated,
compliance with the Consent Order will have a material adverse impact on the
business, results of operations or financial condition of Lockheed Martin and
its subsidiaries taken as a whole or on the operating sectors anticipated to be
organized by Lockheed Martin as reportable business segments. See "BUSINESS OF
LOCKHEED MARTIN" and "RECENT DEVELOPMENTS -- Lockheed Plea Agreement."
 
     At any time before or after the consummation of the Combination, and
notwithstanding that the HSR Act waiting period has expired or been terminated,
any federal or state antitrust authorities could take action under the antitrust
laws as they deem necessary or desirable in the public interest. Such action
could include seeking to enjoin the consummation of the Combination or seeking
divestiture of all or part of the assets of Lockheed or Martin Marietta. Neither
Lockheed nor Martin Marietta is obligated to agree to divest any of its or the
other's material assets in order to obtain governmental approval. See "THE
REORGANIZATION AGREEMENT -- Certain Covenants." Private parties may also seek to
take legal action under the antitrust laws under certain circumstances.
 
     Foreign Approvals. The Combination required antitrust and other filings and
approvals in certain foreign jurisdictions. The parties believe that all
required filings have been made, and all required approvals have been obtained.
If it later appears that any foreign approval which the parties deem to be
material for Lockheed Martin has not been obtained by the time the parties are
otherwise ready to consummate the Combination, the parties may decide to delay
consummation of the Combination or may seek to negotiate with the appropriate
authorities a temporary "hold separate" or other arrangement with respect to
operations in the jurisdiction in question, to the extent necessary to enable
the parties to proceed with consummation of the Combination.
 
CERTAIN LITIGATION
 
     Lockheed, Martin Marietta and the directors of Lockheed are parties to
three lawsuits filed in the Superior Court of the State of California, Richard
Rampell and Frederick Rand v. Daniel M. Tellep, et al., filed August 31, 1994
(the "Rampell Complaint"), Stanton Discount Pharmacy, Inc. v. Daniel M. Tellep,
et al., filed September 12, 1994 (the "Stanton Complaint") and Rose Hadian v.
Daniel M. Tellep, et al., filed October 27, 1994 (the "Hadian Complaint"), and
one lawsuit filed in the Court of Chancery of the State of Delaware entitled
Daniel Lifshitz v. Lockheed Corporation, et al., filed September 26, 1994 (the
"Lifshitz Complaint"). Each of these lawsuits purports to be a class action on
behalf of all Lockheed stockholders similarly situated. Martin Marietta,
Lockheed and the directors of Martin Marietta are parties to a lawsuit filed in
the Superior Court of the State or California, Doris R. Fish v. Marcus C.
Bennett, et al., filed October 26, 1994 (the "Fish Complaint"). This lawsuit
purports to be a class action on behalf of all Martin Marietta stockholders
similarly situated.
 
                                       42
<PAGE>   48
 
     The Rampell Complaint alleges, among other things, that the defendants
either breached or aided and abetted the breach of various fiduciary duties by
(i) failing to maximize stockholder value by conducting an auction for Lockheed
or otherwise seeking out the highest possible bid for Lockheed; (ii) attempting
unfairly to deprive plaintiffs and other members of the class of the true value
of their interest in Lockheed; (iii) placing their personal interests ahead of
those of Lockheed's public stockholders; (iv) using their positions for the
purpose of benefiting themselves to the detriment of plaintiffs and other
members of the class; (v) depriving the stockholders of the opportunity for
substantial gains which Lockheed may realize; (vi) not acting independently so
that the interests of Lockheed's public stockholders would be protected from
conflicts of interest; (vii) failing to take all appropriate steps to enhance
Lockheed's value and attractiveness as a merger, acquisition, restructuring or
recapitalization candidate or to take steps to conduct an active auction for
Lockheed; and (viii) entering into the Combination without regard to the
fairness of the transaction to Lockheed's public stockholders. The Rampell
Complaint seeks to have the court order the defendants to carry out their
fiduciary duties, to enjoin the Combination, to rescind any transaction effected
by the defendants in an unfair manner and for an unfair price in the event that
the Combination is not enjoined, to have defendants account for all profits and
to have all such profits held in constructive trust for the benefit of the
plaintiff class, and for unspecified monetary damages.
 
     The Stanton Complaint alleges, among other things, that the consideration
to be paid to Lockheed stockholders is unconscionable and unfair and grossly
inadequate because, among other things, the intrinsic value of the Lockheed
Common Stock is materially in excess of the amount offered for those securities.
The Stanton Complaint also alleges that the Lockheed directors, aided and
abetted by Martin Marietta, have violated their fiduciary duties by allowing
Martin Marietta to lock up Lockheed prematurely and to effectively cap the price
of Lockheed stock, thus depriving plaintiff and the class of an opportunity to
realize any increase in the value of Lockheed stock and failing to maximize
shareholder value, including by failing to actively pursue the acquisition of
Lockheed by other companies (or conducting an adequate market check) and
otherwise failing to protect the interests of the class. The Stanton Complaint
seeks generally the same relief as the Rampell Complaint.
 
     The Hadian Complaint alleges, among other things, that the consideration to
be paid to Lockheed stockholders is unconscionable and unfair and grossly
inadequate because, among other things, the intrinsic value of the Lockheed
Common Stock is materially in excess of the amount offered for those securities
and the consideration agreed upon did not result from an appropriate
consideration of the value of the Lockheed Common Stock because the Lockheed
directors approved the Combination without adopting proper procedures for
Lockheed's value to be accurately ascertained through open bidding or at least a
"market check" mechanism. The Hadian Complaint also alleges that the
Reorganization Agreement inhibits the maximization of shareholder value and
Lockheed's stockholders will have no effective option other than to accept the
unfair terms of the Reorganization Agreement. Further, the Hadian Complaint
alleges that the Lockheed directors, aided and abetted by Martin Marietta, have
breached their fiduciary duties (i) by adopting a "poison pill" antitakeover
defense and a "lockup fee" provision, both of which are unconscionable and
unreasonable devices, (ii) by allowing Martin Marietta to lock up Lockheed
prematurely, which has allowed the price of the Lockheed Common Stock to be
effectively capped, and (iii) by failing to maximize shareholder value and
protect the interests of the Lockheed stockholders by, among other things,
failing actively to pursue the acquisition of Lockheed by other companies or
conducting an adequate market check. The Hadian Complaint seeks to have the
court (a) enjoin the Combination, (b) require the defendants to make full and
fair disclosure of the material facts prior to consummation of the Combination,
(c) if the Combination is consummated, rescind the transaction, and (d) award
unspecified monetary damages.
 
     The Lifshitz Complaint alleges, among other things, that the Combination is
demonstratively unequal and unfair to Lockheed's stockholders in that the terms
of the Combination ignore Lockheed's greater financial strength and performance
over the past four years. Further, the Lifshitz Complaint alleges that the
defendants breached their fiduciary duties by (i) failing to maximize
shareholder value or engage in open bidding or canvassing of the market to
ensure that the terms of the Combination were fair; (ii) permitting the price of
Lockheed's stock to be effectively capped, thereby depriving the plaintiff and
the class of the opportunity to realize any increase in the value of Lockheed's
stock; (iii) engaging in a scheme, conspiracy
 
                                       43
<PAGE>   49
 
and plan to entrench themselves and unlawfully thwart offers and proposals from
third parties; (iv) failing to fully inform themselves before taking, or
agreeing to refrain from taking, action; (v) failing to act with complete
candor; and (vi) triggering the provisions of the Lockheed Rights Agreement by
permitting a change of control to occur under its terms. As discussed under "THE
COMBINATION -- Background," the directors amended the Lockheed Rights Agreement
on August 29, 1994, to provide that the Combination will not be an event that
triggers the exercisability of rights under the Lockheed Rights Agreement.
 
     The Lifshitz Complaint seeks injunctive relief declaring that the Lockheed
directors have committed a gross abuse of trust and have breached their
fiduciary duties to the plaintiff class, declaring the Lockheed Rights Agreement
void, requiring Lockheed's directors to fulfill their fiduciary duties to
maximize shareholder value by exploring third-party interests and accepting the
highest offer obtainable for the public stockholders or by permitting the
stockholders to make the decision free of any coercion, and for unspecified
monetary damages.
 
     The Fish Complaint alleges, among other things, that the defendants have
engaged in a plan and scheme to benefit themselves at the expense of Martin
Marietta's public stockholders and to deprive them of the true value of their
investment in Martin Marietta. The Fish Complaint further alleges that the
defendants breached their fiduciary duties by: (i) not acting independently so
that the interests of the Martin Marietta public stockholders would be
protected; (ii) not adequately ensuring that no conflicts of interests exist;
(iii) not taking all appropriate steps to enhance Martin Marietta's value and
attractiveness as a merger, acquisition, restructuring or recapitalization
candidate; and (iv) not taking steps to conduct an active auction for Martin
Marietta. In addition, the Fish Complaint alleges that (i) the exchange ratio is
unfair to Martin Marietta stockholders in that it fails to take into account
Martin Marietta's increasing profitability as compared to Lockheed's, (ii) the
exchange ratio is unfair to holders of Martin Marietta Common Stock in that they
will own only a minority stake in Lockheed Martin if GE converts its Martin
Marietta Series A Preferred Stock, (iii) the $100 million termination fee
effectively rules out any serious chance for a fair and free auction and (iv)
the defendants have failed to disclose, among other things, the full extent of
the potential for growth and value potential of Martin Marietta. The Fish
Complaint seeks to have the court (i) order the defendants to carry out their
fiduciary duties, including those of loyalty, due care and candor; (ii) rescind
any transactions effected by the defendants in an unfair manner and for an
unfair price, (iii) enjoin the complained of transaction or any related
transactions and (iv) order defendants to pay monetary damages.
 
     Settlement discussions with respect to the pending litigations began
between the parties on or about January 4, 1995. During these discussions,
counsel for the plaintiffs requested and shortly thereafter received document
discovery from Lockheed and Martin Marietta relating to the Combination. Counsel
for the plaintiffs also announced their intention to consolidate all of the
shareholder class actions into a single case and to file an amended class action
and derivative complaint in California in the lead case, the Rampell Complaint
referenced above, incorporating all of the existing claims from the original
complaints, and adding claims relating to: (i) the formation of Lockheed's
Employee Stock Ownership Plan in 1989 after the disclosure by Valhi, Inc. and
persons related to it that they owned 5.3% of the Lockheed Common Stock; (ii)
Lockheed's plea agreement as described under "RECENT DEVELOPMENTS -- Lockheed
Plea Agreement" and Lockheed's payment of $24.8 million in fines and penalties
to the United States in that action; (iii) the compensation to be paid to
certain Martin Marietta officers and executives as a result of the Combination;
and (iv) disclosures made and proposed to be made to stockholders of Lockheed
and Martin Marietta. The parties continued their discussions regarding a
settlement of the claims alleged in the complaints referred to above (as well as
the claims expected to be alleged in the revised Rampell Complaint) and, in the
course of negotiations, reached an oral agreement in principle on January 30,
1995 with respect to the terms of a proposed settlement of such claims. On
February 2, 1995 the Rampell Complaint was amended to include the allegations
referred to above.
 
     The agreement in principle, which is subject to the execution and delivery
of a mutually-satisfactory stipulation of settlement (a "Stipulation"),
contemplates a settlement subject to Court approval involving the following
elements: (a) Lockheed Martin would agree, subject to any restrictions imposed
by Maryland law, to pay a regular quarterly dividend of $0.40 (rather than
$0.35, as otherwise contemplated) per share on each outstanding share of
Lockheed Martin Common Stock for each of the first three quarters after
consummation
 
                                       44
<PAGE>   50
 
of the Combination and approval of the settlement in which net income (excluding
non-recurring restructure costs and extraordinary charges and transaction
expenses) is sufficient to pay such a dividend; (b) the provisions of Section
6.7 of the Reorganization Agreement would be amended to permit either Lockheed
or Martin Marietta to initiate discussions with third parties regarding business
combination transactions if either company's Board of Directors, upon written
advice of counsel, has determined that it is in the best interests of such
company's stockholders to initiate such discussions; (c) the termination fee
specified in Section 8.2 of the Reorganization Agreement would be reduced from
$100 million to $50 million; (d) this Joint Proxy Statement/Prospectus would
reflect certain additional disclosures proposed by counsel for plaintiffs; (e)
in part as a result of the pendency of the plaintiffs' actions, Lockheed would
agree to strengthen its policies and procedures to help to insure compliance
with the Foreign Corrupt Practices Act; and (f) Lockheed Martin would agree to
the payment of $6 million in counsel fees and expenses to plaintiffs' counsel
with interest from the date plaintiffs' counsel delivers to defendants' counsel
a draft of the Stipulation.
 
     It is contemplated that the proposed settlement will be expressly
conditioned upon (i) the Combination being consummated substantially on the
terms set forth in the Reorganization Agreement, (ii) Lockheed and Martin
Marietta receiving evidence satisfactory to them that the provisions of the
proposed settlement will not result in the pooling of interests method of
accounting for the Combination being unavailable under the requirements of APB
No. 16; (iii) certification of the stockholder classes (for the purpose of
obtaining approval of the Stipulation and entry of an appropriate judgment);
(iv) court approval of the Stipulation; and (v) final dismissal of the actions
with prejudice and release of the claims asserted in such actions with
prejudice.
 
     As discussed above, the Combination is structured as a "merger of equals"
and does not involve a sale of Lockheed or Martin Marietta, and the Lockheed
Board and the Martin Marietta Board have thoroughly reviewed the terms and
conditions of the Combination and have determined that the Combination is in the
best interests of their respective stockholders (see "-- Background",
"-- Recommendation of Lockheed Board; Lockheed's Reasons for the Combination"
and "-- Recommendation of Martin Marietta Board; Martin Marietta's Reasons for
the Combination"). Lockheed, Martin Marietta and the other defendants have
denied, and continue to deny, that they have committed any violations of law,
and they have agreed in principle to the proposed settlement in order to
eliminate the burden and expense of further litigation and to facilitate the
consummation of a transaction that they believe to be in the best interests of
the stockholders of Lockheed and Martin Marietta. On February 7, 1995 Lockheed,
Martin Marietta and Lockheed Martin made the amendments to Sections 6.7 and 8.2
of the Reorganization Agreement contemplated by the terms of the proposed
settlement. Prior to reaching the agreement in principle described above,
plaintiffs' counsel reviewed the internal financial forecasts for Lockheed
through 1998 prepared by management of Lockheed and reviewed by Lockheed's Board
in connection with its consideration of the Combination. See "-- Recommendation
of Lockheed Board; Lockheed's Reasons for the Combination". If the proposed
settlement described above is not consummated, Lockheed, the Lockheed directors,
Martin Marietta and the Martin Marietta directors intend to contest the claims
asserted against them in these lawsuits.
 
STOCK EXCHANGE LISTING
 
     Lockheed Martin expects to apply for the listing of Lockheed Martin Common
Stock on the NYSE, and it is anticipated that such shares will trade on the NYSE
upon official notice of issuance, under the symbol LMT. It is a condition to the
Combination that the shares of Lockheed Martin Common Stock issuable in the
Combination be approved for listing on the NYSE upon official notice of
issuance.
 
DELISTING AND DEREGISTRATION OF LOCKHEED COMMON STOCK AND MARTIN MARIETTA COMMON
STOCK; CESSATION OF PERIODIC REPORTING
 
     If the Combination is consummated, Lockheed Common Stock and Martin
Marietta Common Stock will cease to be listed on the NYSE and the other
exchanges on which such securities are listed. In such event, Lockheed Martin
intends to apply to the Commission for the deregistration of such securities. In
addition,
 
                                       45
<PAGE>   51
 
Lockheed Martin may guarantee Lockheed's or Martin Marietta's publicly held debt
(or a portion of such debt). In such event, Lockheed or Martin Marietta, as the
case may be, intends to seek to obtain a no-action letter from the Commission
permitting it to cease filing periodic reports pursuant to the Exchange Act.
 
FEDERAL SECURITIES LAWS CONSEQUENCES
 
     All shares of Lockheed Martin Common Stock received by Lockheed and Martin
Marietta stockholders in the Combination will be freely transferable, except
that shares of Lockheed Martin Common Stock received by persons who are deemed
to be "affiliates" (as such term is defined under the Act) of Lockheed or Martin
Marietta prior to the Combination may be resold by them only in transactions
permitted by the resale provisions of Rule 145 promulgated under the Act (or
Rule 144 in the case of such persons who become affiliates of Lockheed Martin)
or as otherwise permitted under the Act. Persons who may be deemed to be
affiliates of Lockheed, Martin Marietta or Lockheed Martin generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include certain officers and directors of such
party as well as principal stockholders of such party. The Reorganization
Agreement requires Lockheed and Martin Marietta to use reasonable efforts to
cause each of their affiliates to execute a written agreement to the effect that
such persons will not offer or sell or otherwise dispose of any of the shares of
Lockheed Martin Common Stock or Lockheed Martin Series A Preferred Stock, as the
case may be, issued to such persons in or pursuant to the Combination in
violation of the Act or the rules and regulations promulgated by the Commission
thereunder.
 
APPRAISAL RIGHTS
 
     Holders of Lockheed Common Stock are not entitled to dissenters' or
appraisal rights in connection with the Pacific Sub Merger because the Lockheed
Common Stock is listed on a national securities exchange and the shares of
Lockheed Martin Common Stock that such holders will be entitled to receive in
the Pacific Sub Merger will also be listed on a national securities exchange.
Holders of Martin Marietta Common Stock are not entitled to dissenters' or
appraisal rights in connection with the Atlantic Sub Merger because the Martin
Marietta Common Stock is listed on a national securities exchange.
 
     GE, as the holder of Martin Marietta Series A Preferred Stock, is entitled
to exercise appraisal rights under Title 3, Subtitle 2 of the MGCL. However, the
management of GE has agreed to recommend to its Board of Directors that such
shares be voted in favor of the Combination Proposal and not to assert any
dissenters' or appraisal rights under the MGCL in connection with the
transactions set forth in the Reorganization Agreement. See "OWNERSHIP OF
LOCKHEED, MARTIN MARIETTA AND LOCKHEED MARTIN -- Martin Marietta."
 
                          THE REORGANIZATION AGREEMENT
 
GENERAL
 
     The Reorganization Agreement provides for the merger of Atlantic Sub and
Pacific Sub with and into Martin Marietta and Lockheed, respectively. As a
result of the Combination, Martin Marietta and Lockheed will become wholly owned
subsidiaries of Lockheed Martin. In the Combination, stockholders of Martin
Marietta and Lockheed will receive the consideration described below. The
Combination will be accomplished pursuant to the Mergers. The Mergers will
become effective in accordance with Articles of Merger to be filed with the
Department of Assessments and Taxation of the State of Maryland in the case of
the Atlantic Sub Merger, and a Certificate of Merger to be filed with the
Secretary of State of Delaware in the case of the Pacific Sub Merger. Such
filings are anticipated to take place as soon as practicable after the last of
the conditions precedent to the Combination set forth in the Reorganization
Agreement have been satisfied or, where permissible, waived, which is expected
to occur shortly after the Special Meetings. The following description of the
Reorganization Agreement is qualified in its entirety by reference to the
complete text of the Reorganization Agreement, which is incorporated by
reference herein and a copy of which is annexed to this Joint Proxy
Statement/Prospectus as Appendix I.

receive 1.63 shares of Lockheed Martin Common Stock and (ii) each outstanding
share of Lockheed Common Stock owned by Martin Marietta or any subsidiary of
Martin Marietta or held by Lockheed in its treasury will be cancelled and cease
to exist. Fractional shares of Lockheed Martin Common Stock will not be issued
in the Pacific Sub Merger. Holders of Lockheed Common Stock otherwise entitled
to a fractional share will be paid an amount in cash equal to such fractional
part of a share of Lockheed Martin Common Stock multiplied by the closing price
of a share of Lockheed Martin Common Stock on the NYSE on the last business day
preceding the Merger Date if such stock is then being traded, including without
limitation trading on a "when issued" basis, and otherwise the closing price on
the first business day that such stock is traded. For a description of Lockheed
Martin Common Stock, see "DESCRIPTION OF LOCKHEED MARTIN CAPITAL STOCK -- Common
Stock."
 
     For a description of the treatment of Lockheed and Martin Marietta stock
options and other employee benefit plans under the Reorganization Agreement, see
"-- Certain Benefits Matters" and "THE COMBINATION -- Interests of Certain
Persons in the Combination."
 
     Exchange of Shares. Promptly after the Merger Date, transmittal forms will
be mailed to each holder of record of shares of Lockheed Common Stock, Martin
Marietta Common Stock and Martin Marietta Series A Preferred Stock to be used in
forwarding certificates evidencing such shares for surrender and exchange for
certificates evidencing the shares of Lockheed Martin Common Stock or Lockheed
Martin Series A Preferred Stock, as the case may be, to which such holder has
become entitled and, if applicable, cash in lieu of a fractional share of
Lockheed Martin Common Stock. After receipt of such transmittal form, each
holder of certificates formerly representing Lockheed Common Stock, Martin
Marietta Common Stock or Martin Marietta Series A Preferred Stock should
surrender such certificates, together with a duly completed transmittal form, to
First Chicago Trust Company of New York, as exchange agent (the "Exchange
Agent"), and each such holder will receive in exchange therefor certificates
evidencing the whole number of shares of Lockheed Martin Common Stock or
Lockheed Martin Series A Preferred Stock, as the case may be, to which he or she
is entitled and any cash which may be payable in lieu of a fractional share.
Such transmittal forms will be accompanied by instructions specifying other
details of the exchange.
 
     STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL THEY RECEIVE A
TRANSMITTAL FORM.
 
     After the Merger Date, each certificate evidencing Martin Marietta Common
Stock or Martin Marietta Series A Preferred Stock (other than certificates
evidencing shares owned by Lockheed or its subsidiaries (which will be
cancelled)), or Lockheed Common Stock (other than certificates evidencing shares
owned by Martin Marietta or its subsidiaries or shares held by Lockheed in its
treasury (which will be cancelled)), until so surrendered and exchanged, will be
deemed, for all purposes, to evidence only the right to receive the number of
shares of Lockheed Martin Common Stock or Lockheed Martin Series A Preferred
Stock, as the case may be, which the holder of such certificate is entitled to
receive and the right to receive any cash payment in lieu of a fractional share
of Lockheed Martin Common Stock. The holder of such unexchanged certificate will
not be entitled to receive any dividends or other distributions payable by
Lockheed Martin until the certificate is surrendered. Subject to applicable laws
such dividends and distributions, if any, will be
 
                                       47
<PAGE>   53
 
accumulated and, at the time of such surrender, all such unpaid dividends and
distributions, together with any cash payment in lieu of a fractional share,
will be paid, without interest.
 
LOCKHEED MARTIN FOLLOWING THE COMBINATION
 
     The Reorganization Agreement provides that the Board of Directors of
Lockheed Martin (the "Lockheed Martin Board") will have 24 members, twelve of
whom will initially be designated by Martin Marietta and twelve of whom will
initially be designated by Lockheed. Membership on the major committees of the
Lockheed Martin Board will initially consist of an equal number of designees of
Martin Marietta and Lockheed. See "MANAGEMENT OF LOCKHEED MARTIN -- Directors"
and "-- Committees of the Board of Directors." In addition, the Reorganization
Agreement states that it is the intention of the parties thereto that the
initial quarterly dividend with respect to Lockheed Martin Common Stock will be
at the annual rate of $1.40 per share, subject to approval and declaration by
the Lockheed Martin Board. (See "THE COMBINATION -- Certain Litigation" for a
description of a proposed litigation settlement that would, if consummated,
result in an increase in the rate of such dividend for three quarters following
consummation of the Combination.)

applicable law and regulation to consummate and make effective the Combination
in accordance with the terms of the Reorganization Agreement and the related
merger agreements. Martin Marietta and Lockheed are not required, however, to
agree to the divestiture of any of its or the other party's material assets in
order to obtain any governmental approval.
 
NO SOLICITATION OF TRANSACTIONS
 
     The Reorganization Agreement provides that neither Martin Marietta nor
Lockheed nor any of their respective officers, directors or agents will directly
or indirectly, encourage, solicit or initiate discussions or negotiations with,
or engage in negotiations or discussions with, or provide any nonpublic
information to, any corporation, partnership, person or other entity or group

                                       49
<PAGE>   55
 
determined that it is in the best interests of such company's stockholders to do
so. In the event Martin Marietta or Lockheed receives any proposal concerning
any such transaction, such party shall promptly advise the other as to any such
proposal and as to any discussions conducted in connection therewith.
 
CERTAIN BENEFITS MATTERS
 
     Pursuant to the Reorganization Agreement, simultaneously with the Atlantic
Sub Merger, (i) each outstanding option to purchase or acquire a share of Martin
Marietta Common Stock under option plans presently maintained by Martin Marietta
("Martin Marietta Option Plans") will be converted into an option to purchase
that number of shares of Lockheed Martin Common Stock which could have been
obtained upon the exercise of such option at the same exercise price, and all
references in each such option to Martin Marietta shall be deemed to refer to
Lockheed Martin, where appropriate, (ii) each outstanding stock appreciation
right under the Martin Marietta Option Plans ("Martin Marietta SAR") to receive
a cash payment based on the Martin Marietta Common Stock will be converted into
a stock appreciation right to receive a cash payment based on the same number of
shares of Lockheed Martin Common Stock and at the same base price as applied to
the Martin Marietta SAR, and all references in each Martin Marietta SAR to
Martin Marietta shall be deemed to refer to Lockheed Martin, where appropriate,
(iii) Lockheed Martin will assume the obligations of Martin Marietta under the
Martin Marietta Option Plans and (iv) each outstanding award made pursuant to
Martin Marietta's Amended and Restated Long Term Performance Incentive
Compensation Plan and its predecessor plans will be amended or converted into a
similar instrument of Lockheed Martin, in either case with such adjustments to
the terms of such awards, including but not limited to, the formula setting
forth the redemption value of such awards, as are appropriate to preserve the
value inherent in such awards with no detrimental effects on the holders thereof
without their consent. Subject to approval of the Omnibus Plan Proposal, no
additional options or awards will be granted pursuant to the Martin Marietta
Option Plan after the Atlantic Sub Merger. See "THE COMBINATION -- Interests of
Certain Persons in the Combination -- Martin Marietta."
 
     In addition, simultaneously with the Pacific Sub Merger, (i) each
outstanding option (and related stock appreciation right ("Lockheed SAR"), if
any) to purchase or acquire a share of Lockheed Common Stock under option plans
presently maintained by Lockheed ("Lockheed Option Plans") will be converted
into an option (together with a related stock appreciation right of Lockheed
Martin, if applicable), to purchase 1.63 times the number of shares of Lockheed
Martin Common Stock which could have been obtained upon the exercise of each
such option, at an exercise price per share equal to the exercise price for each
such share of Lockheed Common Stock subject to an option (and related Lockheed
SAR, if any) under the Lockheed Option Plans divided by 1.63, and all references
in each such option (and related Lockheed SAR, if any) to Lockheed shall be
deemed to refer to Lockheed Martin, where appropriate and (ii) Lockheed Martin
will assume the obligations of Lockheed under the Lockheed Option Plans. Subject
to approval of the Omnibus Plan Proposal, no additional options or awards will
be granted pursuant to the Lockheed Option Plans after the Pacific Sub Merger.
See "THE COMBINATION -- Interests of Certain Persons in the Combination --
Lockheed."
 
     In the Reorganization Agreement, Martin Marietta and Lockheed have agreed
that effective as of the Merger Date, and subject to approval of the Omnibus
Plan Proposal, Lockheed Martin will adopt the Lockheed Martin Omnibus Plan for
the purpose of granting stock options, restricted stock, stock appreciation
rights or other stock based incentive awards to such employees of Lockheed
Martin, Martin Marietta and Lockheed, and their respective subsidiaries in such
amounts and upon such terms and conditions as the Compensation Committee of the
Lockheed Martin Board, shall, in its sole discretion, determine (subject to the
provisions of the Lockheed Martin Omnibus Plan). See "LOCKHEED MARTIN 1995
OMNIBUS PERFORMANCE AWARD PLAN."
 
INDEMNIFICATION AND INSURANCE
 
     The Reorganization Agreement provides that, for a period of six years after
the Merger Date, Lockheed Martin will cause to be maintained in effect (a) the
current provisions regarding indemnification of officers and directors contained
in the charter and bylaws of Martin Marietta and the certificate of
incorporation and bylaws and officers' and directors' indemnification agreements
of Lockheed, and (b) the current policies of
 
                                       50
<PAGE>   56
 
directors' and officers' liability insurance and fiduciary liability insurance
maintained by Martin Marietta and Lockheed (provided that Lockheed Martin may
substitute therefor policies of at least the same coverage and amounts
containing terms and conditions which are, in the aggregate, no less
advantageous to the insured) with respect to claims arising from facts or events
which occurred on or before the Merger Date.

of Martin Marietta and Lockheed; (b) by Martin Marietta or Lockheed if the
Merger Date shall not have occurred on or before March 31, 1995; (c) by Martin
Marietta or Lockheed if any court of competent jurisdiction in the United States
or other United States governmental body shall have issued an order, decree or
ruling or taken any other action restraining, enjoining or otherwise prohibiting
the Combination on substantially the terms contemplated by the Reorganization
Agreement and such order, decree, ruling or other action shall have become final
and non-appealable; (d) by Martin Marietta if (i) the Lockheed Board shall have
altered its determination to recommend that the stockholders of Lockheed adopt
and approve the Reorganization Agreement or (ii) any third party or group shall
have acquired, after the date of the Reorganization Agreement, beneficial
ownership of 15% or more of the outstanding shares of Lockheed Common Stock; (e)
by Lockheed if (i) the Martin Marietta Board shall have altered its
determination to recommend that the stockholders of Martin Marietta approve the
Reorganization Agreement or (ii) any third party or group shall have acquired,
after the date of the Reorganization Agreement, beneficial ownership of 15% or
more of the outstanding shares of Martin Marietta Common Stock; (f) by Lockheed
or Martin Marietta if there shall have been a material breach by the other of
any of its representations, warranties, covenants or agreements contained in the
Reorganization Agreement and such breach shall not have been cured within 30
days after notice thereof shall have been received by the party alleged to be in
breach; or (g) by Martin Marietta or Lockheed if, other than as a result of a
breach by it, it reasonably concludes that any of the conditions to its
obligations under the Reorganization Agreement described in clauses (b) through
(g) in the first paragraph under "-- Conditions to the Combination" shall have
become impossible of fulfillment. In the event of termination of the
Reorganization Agreement as described in this paragraph, the Reorganization
Agreement will terminate (except for certain provisions relating to the return
of documents, termination fee and expenses), and there will be no other
liability on the part of Martin Marietta or Lockheed to the other except
liability arising under the Confidentiality and Standstill Agreement and arising
out of a willful breach of the Reorganization Agreement.
 
     In the event of a termination by Martin Marietta as described in clause
(d)(i) of the preceding paragraph following receipt by Lockheed of an
Acquisition Proposal (as defined below), or as described in clause (d)(ii) of
the preceding paragraph, or a termination by Lockheed as described in clause
(e)(i) of the preceding paragraph following receipt by Martin Marietta of an
Acquisition Proposal, or as described in clause (e)(ii) of the preceding
paragraph, the terminating party will be paid a fee of $50 million by the other
party within two business days of such termination. For purposes of the
Reorganization Agreement, the term "Acquisition Proposal" means any bona fide
proposal made by a third party to (i) acquire beneficial ownership (as defined
under Rule 13(d) of the Exchange Act) of a majority equity interest in either
Martin Marietta or Lockheed pursuant to a merger, consolidation or other
business combination, sale of shares of capital stock, tender offer or exchange
offer or similar transaction, including, without limitation, any single or
multi-step transaction or series of related transactions which is structured to
permit such third party to acquire beneficial ownership of a majority or greater
equity interest in Martin Marietta or Lockheed, (ii) purchase all or
substantially all of the business or assets of Martin Marietta or Lockheed or
(iii) otherwise effect a business combination involving Martin Marietta or
Lockheed.
 
     Pursuant to the Confidentiality and Standstill Agreement, until March 29,
1997, the parties have agreed that neither Lockheed nor Martin Marietta nor any
of their respective controlled subsidiaries will, unless specifically invited by
the other party, (i) acquire, offer to acquire, or agree to acquire, directly or
indirectly, by purchase or otherwise, any voting securities, or direct or
indirect rights to acquire any voting securities, of the other party, or any
assets of the other party or any subsidiary or division thereof or of any such
successor or controlling person; (ii) make, or in any way participate in,
directly or indirectly, any "solicitation" of "proxies"
 
                                       51
<PAGE>   57
 
(as such terms are used in the rules of the Commission) to vote, or seek to
advise or influence any person or entity with respect to the voting of, any
voting securities of the other party; (iii) make any public announcement with
respect to, or submit a proposal for, or offer of (with or without conditions)
any extraordinary transactions involving the other party or its securities or
assets; or (iv) form, join or in any way participate in a "group" (as defined in
Section 13(d)(3) of the Exchange Act) in connection with any of the foregoing.
The parties also agreed that until March 29, 1997, neither will publicly request
the other (its officers, directors, employees and agents) or publicly disclose
any request, directly or indirectly, to waive any of the provisions described in
this paragraph.
 
EXPENSES
 
     The Reorganization Agreement states that in the event Martin Marietta or
Lockheed fails to recommend the transaction contemplated thereby to its
stockholders, or withdraws any such recommendation previously made and the
Combination is not consummated, such party will (unless a fee has become payable
as described in the second paragraph under "-- Termination" or unless such
failure to recommend or such withdrawal was a result of a breach of the
Reorganization Agreement by the other party) at the time of termination of the
Reorganization Agreement pay to the other party an amount equal to such other
party's actual costs and expenses incurred in connection with the transaction,
provided that such reimbursement shall not exceed $15 million.
 
     Pursuant to the Reorganization Agreement, except as described in the
preceding paragraph, whether or not the Combination is consummated, all costs
and expenses incurred in connection with the transactions contemplated thereby
will be paid by the party incurring such expenses, except that the expenses
incurred in connection with printing this Joint Proxy Statement/Prospectus and
any expenses incurred by Lockheed Martin relating to the issuance, registration
and listing of the Lockheed Martin Common Stock and the Lockheed Martin Series A
Preferred Stock and the qualification thereof under state blue sky or securities
laws, will be paid in equal shares by Martin Marietta and Lockheed.
 
                              BUSINESS OF LOCKHEED
 
     Lockheed's primary businesses involve research, development and production
of aerospace products, systems and services. During 1993, approximately 77% of
sales were to the United States government (approximately 64% in defense
programs and approximately 13% in nondefense programs). During 1993, sales to
foreign governments accounted for approximately 13% of revenues and sales to
commercial customers accounted for approximately 10% of revenues. Sales made to
foreign governments through the United States government are included in sales
to foreign governments.
 
     Lockheed's operating companies are aligned into four segments: Aeronautical
Systems, Missiles and Space Systems, Electronic Systems and Technology Services.
 
     The Aeronautical Systems segment comprises design and production of
fighter/bomber aircraft, special mission and high performance aircraft, and
systems for military operations, for airlift, for antisubmarine warfare, and for
reconnaissance and surveillance; and aircraft modification and maintenance for
military and civilian customers. Lockheed is the prime contractor on the F-16
"Fighting Falcon" fighter aircraft, the F-22 air superiority fighter program and
the C-130 airlift aircrafts. Lockheed is also involved in upgrading aircraft,
including the U-2 reconnaissance aircraft and the F-117 fighter bomber.
 
     The Missiles and Space Systems segment comprises military and civil space
systems, research laboratories, strategic fleet ballistic missiles, tactical
defense missiles and communications systems. Lockheed is the prime contractor on
the Trident II, a submarine launched, strategic deterrent, fleet ballistic
missile, the Milstar communications satellite and the Theater High Altitude Area
Defense (THAAD) program which is intended to be a system capable of intercepting
theater ballistic missiles at high altitudes and long ranges. Lockheed also is a
principal subcontractor on the space station, has contracted to build spacecraft
for Motorola's Iridium TM/SM global communication system and has created a
partnership with two of the Russian Federation's major aerospace firms with
worldwide rights to Russia's Proton rocket, and offers Lockheed Launch Vehicle
services.

     The Electronic Systems segment participates in both defense and commercial
markets. For defense markets, Lockheed develops and manufactures radio
frequency, infrared, and electro-optic countermeasures systems; mission planning
systems; surveillance systems; automated test equipment; antisubmarine warfare
systems; microwave systems; and avionics. Lockheed also manufactures computer
graphics equipment and other electronic products and distributes computer
equipment and workstations for commercial markets worldwide.
 
     The Technology Services segment comprises space shuttle processing,
engineering sciences and support, management of the Idaho National Engineering
Laboratory for the Department of Energy, other environmental services, military
equipment maintenance and support services, airport facilities development and
management, data processing and transaction services.

                              RECENT DEVELOPMENTS
 
1994 RESULTS OF OPERATIONS
 
     Lockheed has reported that sales for 1994 totaled $13.1 billion, unchanged
from 1993. Net earnings for 1994 increased 5%, totalling $445 million, or $7.00
per share, compared with 1993 net earnings of $422 million or $6.70 per share.
Included in Lockheed's 1994 results is a $24.8 million charge related to the
Lockheed plea agreement discussed below under "-- Lockheed Plea Agreement."
 
     Martin Marietta has reported that sales for 1994 totaled $9.87 billion,
representing a 4.6% increase over 1993 sales of $9.44 billion. Net earnings in
1994 increased by 41%, totaling $635.6 million, compared with 1993 earnings of
$450.3 million, before accounting changes. Fully diluted earnings per share were
$5.05 in 1994, a 33% increase over 1993's comparable earnings per share, before
accounting changes, of $3.80.
 
                                       53
<PAGE>   59
 
     Included in the 1994 Martin Marietta results is an after-tax gain of $70.2
million, or $0.56 per share, resulting from the initial public offering by
Martin Marietta Materials, Inc. of 19% of its common stock in February 1994. In
1993, Martin Marietta recognized $429.4 million in non-cash, after-tax charges
associated with changes in accounting for post-retirement and other
post-employment benefits.
 
LOCKHEED PLEA AGREEMENT
 
     On June 22, 1994, an indictment was returned by a federal grand jury
sitting in Atlanta, Georgia, against Lockheed and two of its employees. The
indictment charged that Lockheed and the two employees, one of whom was a
regional vice president of one of Lockheed's subsidiaries and the other a
divisional director of sales for the Middle East and North Africa, violated the
Foreign Corrupt Practices Act (the "FCPA"), conspired to violate the FCPA,
conspired to commit wire fraud, and impaired and impeded agencies of the United
States Department of Defense. The indictment related to allegations that
Lockheed retained a sales and marketing consultant in Egypt who was a member of
the Egyptian Parliament, and that the consultant received retainer payments and
a $1 million contract termination payment in connection with the sale by
Lockheed of three C-130 Hercules Aircraft, in violation of the FCPA.
 
     By letter dated August 18, 1994, the Acting Assistant Secretary, Department
of State, Bureau of Political-Military Affairs ("State Department") advised
Lockheed that it would be the State Department's policy prospectively to deny
defense-related export privileges to Lockheed Aeronautical Systems Company
("LASC"), a division of Lockheed. The State Department, referring to Sections
38, 39 and 42 of the Arms Export Control Act (22 U.S.C. Sections 2778, 2779 and
2791), announced that its action arose from the June 22, 1994, indictment
discussed above. The State Department announced that its action is confined to
LASC and does not affect any other division or subsidiary of Lockheed, although
it is possible that the State Department could expand its action in the future
to cover Lockheed or other divisions of Lockheed or Lockheed Martin or any of
its divisions. Moreover, the State Department announced that the action does not
apply to any approvals granted to LASC's programs before June 22, 1994, but
rather to future export license applications. Lockheed may seek exceptions to
the announced policy on a case-by-case basis at the discretion of the State
Department, Office of Defense Controls, which must consider United States
foreign policy and national security interests, as well as law enforcement
concerns. There is no stated time frame within which the State Department must
review an exception request. As of the date of this Joint Proxy
Statement/Prospectus, Lockheed has submitted written exception requests on
several major aircraft programs. The State Department has granted these requests
in a timely manner consistent with Lockheed's business plans, with no request
pending for more than ninety days. There can be no assurances as to how long the
State Department will take to review any future exception requests or whether
any other exceptions will be granted.
 
     On January 27, 1995, Lockheed and the United States of America entered into
a plea agreement pursuant to which Lockheed agreed to plead guilty to one count
of conspiring to violate the bribery provisions of the FCPA and conspiring to
falsify its books, records and accounts. All other counts of the indictment
referred to above were dismissed. To the knowledge of Lockheed, no directors or
executive officers of Lockheed have been or will be indicted in connection with
this matter. Lockheed agreed to pay the U.S. Government $24.8 million,
consisting of a fine of $21.8 million and a civil settlement of $3 million. The
United States Attorney's Office stated that Lockheed fully cooperated in its
efforts to gather documents and in making witnesses available during the course
of the investigation. The plea agreement does not preclude the possibility that
the Department of Defense, the State Department, or the Commission may take
further action against Lockheed or Lockheed Martin or any of their divisions as
a result of Lockheed's guilty plea, which could include the possibility of
suspension or debarment from future government contracting. Lockheed is
cooperating with these regulatory agencies to satisfy their concerns.
 
                          BUSINESS OF LOCKHEED MARTIN
 
     Lockheed Martin, a newly formed Maryland corporation, has not conducted any
business activities to date, other than those incident to its formation, its
execution of the Reorganization Agreement and related agreements and its
participation in the preparation of this Joint Proxy Statement/Prospectus.
Immediately following the consummation of the Combination, Lockheed Martin will
become a holding company for Lockheed and Martin Marietta and their respective
subsidiaries. Accordingly, the businesses of Lockheed
 
                                       54
<PAGE>   60
 
Martin, through its wholly owned subsidiaries Lockheed and Martin Marietta and
their respective subsidiaries, will be the businesses currently conducted by
Lockheed and Martin Marietta and their respective subsidiaries.
 
     The managements of Lockheed and Martin Marietta currently anticipate that
the businesses of Lockheed Martin will be organized into four major operating
sectors: Aeronautics; Electronics; Information and Technology Services; and
Space and Strategic Missiles. Other units will include Energy Systems, the
Sandia Corporation, Idaho Technologies and Martin Marietta Materials, Inc. It is
expected that initially approximately 40% of Lockheed Martin's sales will be in
civil, commercial and international markets. Following consummation of the
Combination, the management of Lockheed Martin will from time to time evaluate
its businesses and operations and take such actions with respect thereto as it
deems appropriate under then existing circumstances. See "BUSINESS OF LOCKHEED"
and "BUSINESS OF MARTIN MARIETTA."
 
     The managements of Lockheed and Martin Marietta believe that combining the
businesses of the two companies will present important consolidation and synergy
opportunities. It is expected that these opportunities will be derived from
consolidations in central areas such as headquarters, internal information
systems, capital expenditures, procurement, laboratories, travel,
telecommunications, bid proposals and financial services, as well as from
potential consolidation of facilities in the Space and Strategic Missiles,
Electronics, Aeronautics and Information and Technologies Services Sectors.
Savings from these opportunities, a portion of which will accrue to the benefit
of the U.S. Government, are expected to begin to be realized in 1995, with a
phase-in to full benefits over a several-year transition period, although no
assurances can be given that these savings will actually be realized or, if
realized, will occur during the next several years.
 
     The managements of Martin Marietta and Lockheed believe that Lockheed
Martin will have adequate capital resources to operate, compete and grow in an
increasingly challenging and competitive marketplace. As noted above, it is
anticipated that the Combination will present opportunities for Lockheed Martin
to improve operating efficiency, rationalize expenditures and reduce costs, thus
increasing the competitiveness and business prospects of the combined companies
as compared with either company alone. Additionally, the Combination is expected
to result in a more balanced risk profile for Lockheed Martin, financially and
competitively, than either Lockheed or Martin Marietta alone by reducing
dependence on any single program. Finally, the Combination, which will be
accomplished without additional borrowings, is expected to be accomplished on a
tax-free basis and to be accounted for as a pooling of interests transaction
thus avoiding the impact on net income which would, under purchase accounting,
result from the creation and amortization of goodwill. As a consequence of the
foregoing, it is anticipated that the long term effects of the Combination on
the results of operations, liquidity and capital resources of Lockheed and
Martin Marietta will be positive, but a charge against the earnings of Lockheed
Martin will be required for the transition costs and expenses expected to be
incurred in connection with consummating the Combination and integrating the
operations of Lockheed and Martin Marietta (see Note 3 under "NOTES TO UNAUDITED
PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS").
 
     After the consummation of the Combination, Lockheed Martin will require
that sources of credit be available to support the anticipated operations of
Lockheed Martin. It is anticipated that Lockheed Martin will enter into an
agreement or agreements with a syndicate of banks providing for revolving loan
facilities in the amount of $1.5 billion (the "Credit Facilities") to be
effective on the Merger Date. The Credit Facilities are expected to be on
substantially the same terms and conditions as the existing bank credit
facilities of Lockheed and Martin Marietta, with such changes as may be deemed
necessary or desirable by Lockheed Martin and the banks that are parties
thereto. The existing $1 billion credit facility of Lockheed and the existing
$800 million credit facility of Martin Marietta will be terminated effective
immediately prior to the Merger Date.

* Martin Marietta Common Stock prices and dividends have been adjusted for
  2-for-1 stock split (in the form of a stock dividend) effective September 30,
  1993.
 
     On August 29, 1994, the last full trading day prior to the public
announcement of the proposed Combination, the closing price on the NYSE
Composite Tape was $66 per share of Lockheed Common Stock and $48 1/4 per share
of Martin Marietta Common Stock and the Pro Forma Equivalent Price (as defined
below) was $72 1/8 per share for Lockheed Common Stock and $44 1/4 per share for
Martin Marietta Common Stock. On February 8, 1995, the most recent practicable
date prior to the printing of this Joint Proxy Statement/Prospectus, the closing
price on the NYSE Composite Tape was $74 1/8 per share of Lockheed Common Stock
and $45 3/4 per share of Martin Marietta Common Stock and the Pro Forma
Equivalent Price was $74 3/8 per share for Lockheed Common Stock and $45 5/8 per
share for Martin Marietta Common Stock. Pro Forma Equivalent Prices were
determined by (i) multiplying the market prices of Lockheed Common Stock and
Martin Marietta Common Stock on such date by the respective number of shares of
such common stock then outstanding, (ii) dividing the aggregate market value of
the Lockheed Common Stock and Martin Marietta Common Stock so determined by the
number of shares of Lockheed Martin Common Stock to be issued in connection with
the Combination and (iii) multiplying the pro forma market price per share of
Lockheed Martin Common Stock by 1.63 for Lockheed and 1.0 for Martin Marietta.
Holders of Lockheed Common Stock and Martin Marietta Common Stock are urged to
obtain current market quotations prior to making any decision with respect to
the Combination.

* Reflects reclassifications to conform combined condensed balance sheet
  presentation. Martin Marietta's adjustments were attributable to noncurrent
  receivables, inventories, customers' advances, and reserves being reclassified
  as current assets and current liabilities, consistent with Lockheed's policy
  of current classification of similar items for long-term contracts and
  programs whose operating cycles extend beyond one year. Additional
  reclassifications were made by both Lockheed and Martin Marietta to
  consistently report pension amounts, payroll related liabilities, overdrafts
  and environmental items. Income tax balances were also reclassified to be
  consistent with the related asset and liability classifications.

                          NOTES TO UNAUDITED PRO FORMA
                    COMBINED CONDENSED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION
 
     The accompanying unaudited pro forma combined condensed statement of
earnings presents the historical results of operations of Lockheed and Martin
Marietta giving effect to the Combination as if it had occurred at the beginning
of the earliest period presented, combining the results of Lockheed and Martin
Marietta for each of the three fiscal years in the fiscal period ended December
1993 and for the fiscal nine month periods ended September 1994 and 1993. The
unaudited pro forma combined condensed balance sheet gives effect to the
Combination as if it had occurred on the fiscal month end of September 1994,
combining the balance sheets of Lockheed and Martin Marietta at the fiscal month
end of September 1994.
 
2. EXCHANGE RATIO
 
     As described in the Reorganization Agreement, the exchange ratios are: (i)
each outstanding share of Lockheed Common Stock will be converted into the right
to receive 1.63 shares of Lockheed Martin Common Stock; (ii) each outstanding
share of Martin Marietta Common Stock will be converted into the right to
receive one share of Lockheed Martin Common Stock; and (iii) each outstanding
share of Martin Marietta Series A Preferred Stock will be converted into the
right to receive one share of Lockheed Martin Series A Preferred Stock. These
exchange ratios were used in the accompanying unaudited pro forma combined
condensed financial statements. See "THE REORGANIZATION
AGREEMENT -- Consideration to be Received in the Combination."
 
3. TRANSITION COSTS AND EXPENSES
 
     The accompanying unaudited pro forma combined condensed financial
statements do not include any transition costs and expenses which are expected
to be incurred in connection with consummating the Combination and integrating
the operations of Lockheed and Martin Marietta. It is not feasible to determine
the actual amount of these costs and expenses until the Combination is completed
and the related operational and transitional plans are complete. The managements
of Lockheed and Martin Marietta currently estimate that these costs and expenses
could total approximately $850 million. These costs and expenses relate directly
to completing the transactions, such as professional and registration fees;
employee benefit-related costs such as severance, relocation and retention
incentives; facility consolidations; and satisfaction of contractual
obligations; most of which will be incurred to eliminate duplicate facilities
and excess capacity in the combined Lockheed Martin operations. It is
anticipated that a significant portion of these costs and expenses will result
in charges to the earnings of Lockheed Martin. The exact timing of these charges
cannot be determined at this time; however, the managements of Lockheed and
Martin Marietta anticipate that plans and decisions will be completed and a
substantial portion of the related charges recorded in 1995. Additionally, while
the pro forma combined condensed statement of earnings does not reflect any net
cost savings or economies of scale that may be achieved by the Combination, the
Combination is expected to result in reduced costs for Lockheed Martin, a
portion of which will accrue to the benefit of the U.S. Government.

(a) Pro forma adjustments have been recorded to eliminate intercompany sales and
    cost of sales for the fiscal nine month periods ended September 1994 and
    1993, and for the fiscal years ended December 1993, 1992, and 1991. No
    adjustments have been made to eliminate the related intercompany profit in
    ending inventories and the net intercompany receivables and payables as of
    and for the above-referenced fiscal periods as such amounts are not
    material.
(b) Adjustments have been made to reflect the 1992 adoption of SFAS 106 and SFAS
    112 for the combined entity, to conform Lockheed's method of accounting for
    timing differences in cost recognition between Statement of Financial
    Accounting Standards No. 87, Employers' Accounting for Pensions, and
    applicable government contract accounting principles consistent with Martin
    Marietta, and to conform Martin Marietta's to Lockheed's classification of
    state income tax expenses as an element of general and administrative
    costs.
(c) Adjustments have been made to record the tax effect, using the applicable
    federal statutory rates for the respective periods, on the net pro forma
    adjustments.
(d) Adjustments have been made to reflect the exchange ratios, described in Note
    2 above, and the elimination of Treasury Shares in accordance with the
    MGCL.

                       COMPARISON OF STOCKHOLDERS' RIGHTS
 
     At the Merger Date, the stockholders of Martin Marietta and Lockheed will
become stockholders of Lockheed Martin, and their rights will be governed by the
MGCL and Lockheed Martin's charter (the "Lockheed Martin Charter") and bylaws
(the "Lockheed Martin Bylaws") in the forms that will become effective upon the
Merger Date. The following are summaries of certain differences between (i) the
rights of Martin Marietta stockholders and Lockheed Martin stockholders, and
(ii) the rights of Lockheed stockholders and Lockheed Martin stockholders.
 
     The following discussions are not intended to be complete and are qualified
in their entirety by reference to the MGCL, the DGCL, the Lockheed Martin
Charter and Lockheed Martin Bylaws, the charter and bylaws of Martin Marietta
(the "Martin Marietta Charter" and the "Martin Marietta Bylaws," respectively),
and the certificate of incorporation and bylaws of Lockheed (the "Lockheed
Charter" and the "Lockheed Bylaws," respectively), as appropriate. Copies of the
Lockheed Martin Charter and the Lockheed Martin Bylaws, in substantially the
forms to be adopted prior to the consummation of the Combination, are exhibits
to the Reorganization Agreement which is attached to this Joint Proxy
Statement/Prospectus as Appendix I. Copies of the Martin Marietta Charter and
the Martin Marietta Bylaws, and the Lockheed Charter and the Lockheed Bylaws are
incorporated by reference herein and will be sent to holders of shares of Martin
Marietta Common Stock (or Martin Marietta Series A Preferred Stock) and Lockheed
Common Stock, respectively, upon request. See "INCORPORATION OF CERTAIN
DOCUMENTS BY REFERENCE."
 
COMPARISON OF STOCKHOLDER RIGHTS WITH RESPECT TO LOCKHEED MARTIN AND MARTIN
MARIETTA
 
     Since both Lockheed Martin and Martin Marietta are organized under the laws
of the State of Maryland, any differences in the rights of holders of Martin
Marietta Common Stock and Lockheed Martin Common Stock will arise solely from
differences in their respective charters and bylaws. The Lockheed Martin Charter
and Lockheed Martin Bylaws are substantially similar to the Martin Marietta
Charter and Martin Marietta Bylaws, respectively, except for certain matters as
described herein.
 
     Authorized Capital. The total number of authorized shares of capital stock
of Martin Marietta is 550,000,000 shares, consisting of 20,000,000 shares of
Martin Marietta Series A Preferred Stock, 30,000,000 shares of series preferred
stock, par value $1.00 per share (the "Martin Marietta Series Preferred Stock"),
and 500,000,000 shares of Martin Marietta Common Stock. The authorized capital
of Lockheed Martin is as set forth under "DESCRIPTION OF LOCKHEED MARTIN CAPITAL
STOCK -- Authorized Capital Stock."
 
     Directors. The Lockheed Martin Charter provides for 24 directors, which
number may be increased or decreased by the Board of Directors, but which shall
not be less than 12. Pursuant to the Martin Marietta Charter, Martin Marietta
has 17 directors, which number may also be increased or decreased by the Board
of Directors, but not to less than five.
 
     The Lockheed Martin Board will not be divided into separate classes. Each
director will serve until the next annual meeting of stockholders after his or
her election. The Martin Marietta Charter establishes three classes of
directors, as nearly equal in number of directors as possible, with each
director elected for a term expiring at the third succeeding annual meeting of
stockholders after his or her election.
 
     Under the Lockheed Martin Bylaws, the required quorum for any meeting of
the Lockheed Martin Board will generally be a majority of its members. The
Martin Marietta Bylaws provide for a quorum of one-third of the Martin Marietta
Board, but in no case fewer than five directors.
 
     Absence of Rights Plan. Martin Marietta recently adopted a stockholder
rights plan and in connection therewith entered into a Rights Agreement, dated
as of August 29, 1994, with First Chicago Trust Company of New York, as rights
agent (the "Martin Marietta Rights Agreement"). Common stock purchase rights
were distributed to the holders of Martin Marietta Common Stock of record on
September 9, 1994, and rights attach to all shares of Martin Marietta Common
Stock issued thereafter until the earlier of the Distribution Date (as defined
therein), or on the date on which the rights expire or are redeemed. Initially,
the rights trade in tandem with the shares of Martin Marietta Common Stock. The
rights are exercisable only if a person or group acquires 15% or more of Martin
Marietta Common Stock or announces a tender offer for 30% or more
 
                                       65
<PAGE>   71
 
of Martin Marietta Common Stock, subject to certain exceptions specified in the
Martin Marietta Rights Agreement. The rights will expire immediately prior to
the consummation of the transactions contemplated by the Reorganization
Agreement; provided, however, that if the Reorganization Agreement is terminated
without consummation of the transactions contemplated thereby, then the Martin
Marietta Rights Agreement and the rights will expire at or prior to the close of
business on September 9, 2004. Lockheed Martin has not adopted a rights plan at
this time but may decide to do so in the future.
 
COMPARISON OF STOCKHOLDER RIGHTS WITH RESPECT TO LOCKHEED MARTIN AND LOCKHEED
 
     Lockheed Martin is organized under the laws of the State of Maryland and
Lockheed is organized under the laws of the State of Delaware. The following
discussion summarizes certain differences between the Lockheed Martin Charter
and Bylaws and the Lockheed Charter and Bylaws and between certain provisions of
the MGCL and the DGCL affecting stockholders' rights.
 
     Authorized Capital. The total number of authorized shares of capital stock
of Lockheed is 102,500,000, consisting of 2,500,000 shares of preferred stock,
$1.00 par value per share (including 1,000,000 shares of Lockheed Junior
Preferred Stock), and 100,000,000 shares of Lockheed Common Stock. The
authorized capital of Lockheed Martin is as set forth under "DESCRIPTION OF
LOCKHEED MARTIN CAPITAL STOCK -- Authorized Capital Stock."
 
     Directors. The Lockheed Bylaws provide for a minimum of three directors
(except in connection with rights to elect directors granted to holders of any
class or series of Lockheed preferred stock), with the exact number of directors
to be fixed from time to time by the Lockheed Board. There are currently 14
directors serving on the Lockheed Board. The Lockheed Martin Charter provides
for 24 directors, which number may be increased or decreased by the Lockheed
Martin Board, but which shall not be less than 12.
 
     The Lockheed Bylaws provide that a plurality of stockholder votes cast will
be sufficient to elect a director. The Lockheed Martin Bylaws require the vote
of stockholders representing a majority of the votes entitled to be cast to
elect a director. In addition, under the Lockheed Martin Charter, if any person
beneficially owns shares of capital stock entitled to vote generally in the
election of directors ("Voting Stock") representing 40% or more of the votes
entitled to be cast by all stockholders, the Lockheed Martin Board will be
elected by cumulative voting.
 
     Under the Lockheed Bylaws, a majority of any quorum of the Lockheed Board
must consist of directors who are not or have not theretofore ever been
employees of, or who do not have or have not had other business or professional
relations with, Lockheed. The Lockheed Martin Bylaws have no analogous
provision.
 
     Removal of Directors. The Lockheed Charter provides that, except with
respect to additional directors elected under specified circumstances by holders
of any class or series of Lockheed preferred stock, any director may be removed
by a vote of the majority of the outstanding shares entitled to vote in
connection with the election of such director, regardless of class, voting
together as a single class. The Lockheed Martin Charter provides that directors
may be removed, only for cause, by the affirmative vote of at least 80% of the
votes that the holders of the outstanding shares of capital stock are entitled
to cast at the annual election of directors.
 
     Filling Vacancies on the Board of Directors. Under the DGCL, vacancies and
newly created directorships may be filled by a majority of the directors then in
office or a sole remaining director (even though less than a quorum) unless
otherwise provided in the certificate of incorporation or bylaws. However, the
DGCL also provides that if the directors then in office constitute less than a
majority of the corporation's board of directors, then, upon application by
stockholders representing at least 10% of outstanding shares entitled to vote
for such directors, the Court of Chancery may order a stockholder election of
directors to be held. Under the Lockheed Bylaws, except with respect to
additional directors elected under specified circumstances by holders of any
class or series of Lockheed preferred stock, any vacancies resulting from death,
resignation, disqualification, removal or other cause or an increase in the
number of directors shall be filled solely by a majority vote of the remaining
directors, even if less than a quorum.
 
     Under the Lockheed Martin Charter and the Lockheed Martin Bylaws, a
majority of the remaining directors may appoint a director to fill a vacancy
unless there is an increase in the size of the Lockheed Martin
 
                                       66
<PAGE>   72
 
Board. Any vacancy resulting from an increase shall be filled only by a majority
vote of the entire Lockheed Martin Board. If the vacancy is caused by removal of
a director by the stockholders, the successor director may be elected by the
stockholders at the same meeting at which such removal occurs. Under the
Lockheed Martin Charter, the provision with respect to election of directors to
fill vacancies may be amended or repealed only by the affirmative vote of at
least 80% of the votes entitled to be cast in the election of directors.
 
     Amendment to Certificate of Incorporation or Charter. Under the DGCL and
the Lockheed Charter, the affirmative vote of a majority of the outstanding
shares entitled to vote is required to amend the Lockheed Charter. In addition,
amendments which make changes relating to the capital stock by increasing or
decreasing the par value or the aggregate number of authorized shares of a class
or otherwise adversely affecting the rights of such class, must be approved by
the majority vote of each class or series of stock affected, even though
ordinarily they would not have such voting rights.
 
     In accordance with the MGCL, under the Lockheed Martin Charter, except as
described below or in connection with the rights of the holders of any class or
series of Lockheed Martin Preferred Stock, the affirmative vote of a majority of
the outstanding shares entitled to vote is necessary to amend the Lockheed
Martin Charter. The affirmative vote of 80% of the votes that the holders of the
then outstanding shares of capital stock would be entitled to cast at an annual
election of directors is required to amend Sections 3 or 5 of Article V of the
Lockheed Martin Charter relating to removal of directors and the general powers
of the board of directors. Any amendment to Article XIII of the Lockheed Martin
Charter regarding "business combinations" requires the affirmative vote of (a)
80% of the outstanding shares of Voting Stock and (b) 67% of the outstanding
shares of Voting Stock excluding shares held by certain beneficial owners of 10%
or more of the outstanding shares of any class or series of Voting Stock (as
defined in the Lockheed Martin Charter, a "Related Person"), unless such
amendment shall have been approved in advance by not less than two-thirds of the
Lockheed Martin "continuing directors" (as defined in such Article XIII). Any
amendment to Article XIV of the Lockheed Martin Charter regarding certain
prohibitions on greenmail requires the affirmative vote of 80% of the votes
entitled to be cast by holders of shares of Voting Stock.
 
     Amendment of Bylaws. Under the DGCL, the Lockheed Bylaws and the Lockheed
Charter, the Lockheed Bylaws may be amended by the action of the Lockheed Board
or by the affirmative vote of a majority of the outstanding shares of stock,
voting as a single class.
 
     Under the MGCL, the power to adopt, amend or repeal a corporation's bylaws
is vested in the corporation's stockholders, except to the extent the
corporation's charter or bylaws vest it in the board of directors. The Lockheed
Martin Bylaws grant the Lockheed Martin Board exclusive power to adopt, amend,
alter or repeal the Lockheed Martin Bylaws.
 
     Advance Notice of Director Nominations and New Business. The Lockheed
Bylaws provide that with respect to any stockholder meeting, nominations of
persons for election to the Lockheed Board and the proposal of business to be
considered by stockholders may be made only (a) by or at the direction of the
Lockheed Board or (b) by a stockholder who has complied with the advance notice
procedures set forth in the Lockheed Bylaws.
 
     The Lockheed Martin Bylaws provide that (a) with respect to an annual
meeting of stockholders, nominations of persons for election to the Lockheed
Martin Board and the proposal of business to be considered by stockholders may
be made only (i) pursuant to Lockheed Martin's notice of the meeting, (ii) by or
at the direction of the Lockheed Martin Board or (iii) by a stockholder who has
complied with the advance notice procedures set forth in the Lockheed Martin
Bylaws and is entitled to vote at the meeting, and (b) with respect to special
meetings of stockholders, only the business specified in Lockheed Martin's
notice of meeting may be brought before the meeting and nominations of persons
for election to the Lockheed Martin Board may be made only pursuant to Lockheed
Martin's notice of the meeting (i) by or at the direction of the Lockheed Martin
Board or (ii) by a stockholder who has complied with the advance notice
procedures set forth in the Lockheed Martin Bylaws and is entitled to vote at
the meeting.
 
     Stockholder Meetings and Provisions for Notices. Under the DGCL and the
MGCL, stockholder meetings may be held at any place within or without the state,
as provided in the bylaws, provided that under
 
                                       67
<PAGE>   73
 
the MGCL, stockholder meetings must be held in the United States. Under the
Lockheed Bylaws, special stockholder meetings may be called by a majority of the
Lockheed Board or the Chairman or the Vice Chairman of the Lockheed Board. Under
the Lockheed Martin Bylaws, special stockholder meetings may be called by the
Executive Committee of the Lockheed Martin Board, a majority of the Lockheed
Martin Board, the Chairman of the Lockheed Martin Board, the President or by the
Secretary at the written request of stockholders entitled to cast at least 25%
of the votes entitled to be cast at such meeting. Under the MGCL, unless
requested by the holders of a majority of shares entitled to vote thereon, a
special meeting of stockholders does not need to be called to consider any
matter that is substantially the same as a matter voted on at a special meeting
held within the preceding 12 months.
 
     Under both the DGCL and the MGCL, written notice of a stockholders meeting
must state the place, date and time of the meeting, and if a special meeting,
the purpose. Under the Lockheed Bylaws, such notice must be delivered personally
or by mail not less than ten nor more than 60 days prior to the meeting. Under
the Lockheed Martin Bylaws, such notice must be delivered personally or mailed
not less than 30 nor more than 90 days prior to the meeting.
 
     In accordance with the DGCL, the Lockheed Bylaws provide that stockholder
proxies are valid for three years from their date unless the proxy provides for
a longer period. The MGCL and the Lockheed Martin Bylaws provide that proxies
are valid for 11 months from their date, unless the proxy otherwise provides.
 
     Voting by Stockholders. Under the Lockheed Bylaws, except with respect to
the election of directors (or as otherwise provided by the Lockheed Charter, the
Lockheed Bylaws, or by applicable law), action by Lockheed stockholders is taken
by the vote, at a meeting at which a quorum is present, of the holders of a
majority of the outstanding shares entitled to vote thereon. However, subject to
applicable law and the Lockheed Charter, the Lockheed Bylaws allow the Lockheed
Board to require a larger vote upon any question or election. Under the Lockheed
Martin Charter, except with respect to the amendment of certain provisions
thereof (or as otherwise provided by the Lockheed Martin Charter or by
applicable law), action by Lockheed Martin stockholders generally is taken by
the affirmative vote, at a meeting at which a quorum is present, of stockholders
representing a majority of all votes entitled to be cast on the matter
(including without limitation, certain extraordinary actions, such as mergers,
consolidations and charter amendments, that under the MGCL would, absent
provision in the Lockheed Martin Charter, require the affirmative vote of
two-thirds of the votes entitled to be cast thereon).
 
     Stockholder Action Without a Meeting. Under the Lockheed Charter,
consistent with the DGCL, no action may be taken by the stockholders except at a
meeting. Under the MGCL, Lockheed Martin stockholders may act by unanimous
written consent provided certain conditions are met.
 
     Absence of Rights Plan. Lockheed entered into the Lockheed Rights Agreement
in 1986. Lockheed Martin has not adopted a rights plan at this time but may
decide to do so in the future.
 
     Business Combinations. Under the MGCL, certain "business combinations"
(including a merger, consolidation, share exchange or, in certain circumstances,
an asset transfer or issuance or reclassification of equity securities) with
certain "interested stockholders" (as defined for purposes of such provisions)
may be prohibited for a five-year period and thereafter may be subject to, among
other things, certain stockholder approvals. See "DESCRIPTION OF LOCKHEED MARTIN
CAPITAL STOCK -- Certain Antitakeover Effects of Lockheed Martin Charter and
Bylaws and Maryland Law -- Business Combinations."
 
     In addition to the MGCL requirements, the Lockheed Martin Charter also
contains a provision requiring that, subject to certain exceptions, any
"business combination" between Lockheed Martin and a Related Person must be
approved by 80% of the outstanding shares of Voting Stock and by 67% of the
outstanding shares of Voting Stock not owned by the Related Person. See
"DESCRIPTION OF LOCKHEED MARTIN CAPITAL STOCK -- Certain Antitakeover Effects of
Lockheed Martin Charter and Bylaws and Maryland Law -- Business Combinations."
 
     Under Section 203 of the DGCL ("Section 203"), certain "business
combinations" with "interested stockholders" (each as defined in Section 203) of
Delaware corporations are subject to a three-year
 
                                       68
<PAGE>   74
 
moratorium unless specified conditions are met. The provisions of Section 203 do
not apply to Lockheed because Lockheed elected not to be subject to the
provisions of Section 203.
 
     Control Share Acquisitions.  Under the MGCL, stock acquired in certain
"control share" acquisitions has no voting rights except to the extent approved
by a vote of two-thirds of the votes entitled to be cast by stockholders in the
election of directors, excluding shares of stock as to which the acquiring
person, officers of the corporation and directors of the corporation who are
employees of the corporation are entitled to exercise or direct the exercise of
the voting power of the shares in the election of directors. See "DESCRIPTION OF
LOCKHEED MARTIN CAPITAL STOCK -- Certain Antitakeover Effects of Lockheed Martin
Charter and Bylaws and Maryland Law -- Control Share Acquisitions." The DGCL has
no comparable control share acquisition statute.
 
     Indemnification and Limitation of Liability. Delaware and Maryland have
similar laws respecting indemnification by a corporation of its officers,
directors, employees and other agents. The laws of both states also permit, with
certain exceptions, corporations to adopt a provision in their certificate of
incorporation or charter eliminating the liability of a director to the
corporation or its stockholders for monetary damages for breach of the
director's fiduciary duty of care. There are nonetheless certain differences
between the laws of the two states respecting indemnification and limitation of
liability.
 
     The Lockheed Charter eliminates the liability of directors to the fullest
extent permissible under the DGCL, as such law exists currently or as it may be
amended in the future. Such provision may not eliminate or limit director
monetary liability for (a) breaches of the director's duty of loyalty to the
corporation or its stockholders; (b) acts or omissions not in good faith or
involving intentional misconduct or knowing violations of law; (c) the payment
of unlawful dividends or unlawful stock repurchases or redemptions; or (d)
transactions in which the director received an improper personal benefit. The
DGCL provides that indemnification is mandatory to the extent a director,
officer, employee or agent acting in good faith and in a manner he or she
reasonably believed to be in, or not opposed to, the best interests of the
corporation, or with respect to any criminal action or proceeding, there was no
reason to believe his or her conduct was unlawful, or has been successful on the
merits or otherwise in the defense of any proceeding covered by the
indemnification statute.
 
     The DGCL generally permits (and the Lockheed Charter therefore requires)
indemnification for expenses incurred in the defense or settlement of derivative
or third-party actions, provided there is a determination by a quorum of
directors who were not parties to the action, or if such quorum is not
obtainable or if directed by such quorum by independent legal counsel or by a
majority vote of a quorum of the stockholders, that the person seeking
indemnification acted in good faith and in a manner reasonably believed to be
in, or not opposed to, the best interests of the corporation, or in a criminal
proceeding that the person had no reason to believe his or her conduct to be
unlawful. Without court approval, however, no indemnification may be made in
respect of any derivative action in which such person is adjudged liable. The
DGCL states that the indemnification provided by statute shall not be deemed
exclusive of any other rights under any bylaw, agreement, vote of stockholders
or disinterested directors or otherwise.
 
     The Lockheed Martin Charter limits the monetary liability of both officers
and directors to the maximum extent permissible under the MGCL. The exceptions
to such a liability limitation in the charter of a Maryland corporation
generally are to the extent that (a) it is proved that the person received an
improper benefit or profit in money, property or services, for the amount of
benefit or profit so received, and (b) a judgment or other final adjudication
adverse to the person is entered in a proceeding based on a finding that the
person's action or failure to act was the result of active and deliberate
dishonesty and was material to the cause of action. Under the MGCL, unless
limited by the charter, indemnification is mandatory if a director or an officer
has been successful on the merits or otherwise in the defense of any proceeding
by reason of his or her service as a director unless such indemnification is not
otherwise permitted as described in the following sentence. Indemnification is
permissive unless it is established that (a) the act or omission of the director
was material to the matter giving rise to the proceeding and was committed in
bad faith or was the result of active and deliberate dishonesty, (b) the
director actually received an improper personal benefit in money, property or
services or (c) in the case of a criminal proceeding, the director had

act or omission was unlawful. In addition to the foregoing, a court of
appropriate jurisdiction may under certain circumstances order indemnification
if it determines that the director or officer is fairly and reasonably entitled
to indemnification in view of all the relevant circumstances, whether or not the
director or officer has met the standards of conduct set forth in the preceding
sentence or has been adjudged liable on the basis that a personal benefit was
improperly received in a proceeding charging improper personal benefit to the
director or the officer. If the proceeding was an action by or in the right of
the corporation or involved a determination that the director or officer
received an improper personal benefit, however, no indemnification may be made
if the individual is adjudged liable to the corporation, except to the extent of
expenses approved by a court of appropriate jurisdiction.
 
     Under the MGCL, where indemnification is permissible it must be authorized
(a) by the board of directors by a majority vote of a quorum consisting of
directors who are not parties to the proceeding (or if such a quorum cannot be
obtained, the determination may be made by a majority vote of a committee of the
board which consists solely of two or more directors who are not parties to the
proceeding and who were designated to act by a majority of the full board), (b)
by special legal counsel selected by the board of directors or by a committee of
the board (or if the requisite quorum of the board cannot be obtained and the
committee cannot be established, a majority of the full board, including
directors who are parties, may select the special counsel), or (c) by a vote of
the stockholders other than those stockholder-directors who are party to the
proceedings.
 
     In Maryland, expenses may be advanced to a director, and to an officer,
employee or agent who is not a director to the same extent that they may be
advanced to a director unless limited by the charter. Advances to officers,
employees and agents may be generally authorized in the corporation's charter or
bylaws, by action of the board of directors or by contract. Delaware law permits
such general authorization of advances to directors and officers but requires
approval by the directors of advances to employees and agents of the
corporation.
 
     Dissenter's or Appraisal Rights. Under the DGCL, a stockholder of a
corporation who does not consent to certain major corporate transactions may,
under varying circumstances, be entitled to dissenter's or appraisal rights
pursuant to which such stockholder may receive cash in the amount of the fair
market value of his or her shares in lieu of the consideration he or she would
otherwise receive in the transaction. Unless the corporation's certificate of
incorporation provides otherwise, such appraisal rights are not available in
certain circumstances, including without limitation (a) with respect to the
sale, lease or exchange of all or substantially all of the assets of a
corporation, (b) with respect to a merger or consolidation by a corporation the
shares of which are either listed on a national securities exchange or are held
of record by more than 2,000 holders if such stockholders receive only shares of
the surviving corporation or shares of any other corporation which are either
listed on a national securities exchange or held of record by more than 2,000
holders, plus cash in lieu of fractional shares, or (c) to stockholders of a
corporation surviving a merger if no vote of the stockholders of the surviving
corporation is required to approve the merger because the merger agreement does
not amend the existing certificate of incorporation, each share of the surviving
corporation outstanding prior to the merger is an identical outstanding or
treasury share after the merger, and the number of shares to be issued in the
merger does not exceed 20% of the shares of the surviving corporation
outstanding immediately prior to the merger and if certain other conditions are
met. Under Delaware law, dissenter's or appraisal rights are not available to
Lockheed stockholders in connection with the Combination.
 
     Under the MGCL, stockholders have the right to demand and to receive
payment of the fair value of their stock in the event of (a) a merger or
consolidation, (b) a share exchange, (c) certain sales of all or substantially
all of the assets, (d) a charter amendment altering contract rights of
outstanding stock, as expressly set forth in the charter, and substantially
adversely affecting the stockholder's rights (unless, as is the case with the
Lockheed Martin Charter, the right to do so is reserved in the charter), or (e)
certain business combinations with interested stockholders which are subject to
or exempted from the MGCL's business combination statute and in connection with
the approval of voting rights of certain stockholders under the MGCL's control
share acquisition statute. Except with respect to certain business combinations
and in connection with appraisal and dissenters' rights existing as a result of
the MGCL's control share acquisition statute, the right to demand and receive
payment of fair value does not apply to (a) stock listed on a national
securities exchange or a national market system security designated on an
interdealer quotation system by the
 
                                       70
<PAGE>   76
 
National Association of Securities Dealers, Inc., (b) stock of the successor in
a merger (unless the merger alters the contract rights of the stock or converts
the stock in whole or in part into something other than stock, cash, scrip or
other interests) or (c) stock of an open-end investment company registered with
the Commission under the Investment Company Act of 1940 and the stock is valued
in the transaction at its net asset value. Except in the case of appraisal and
dissenters' rights existing as a result of the MGCL's control share acquisition
statutes, these rights are available only when the stockholder (a) files with
the corporation a timely, written objection to the transaction and (b) does not
vote in favor of the transaction. In addition, the stockholder must make a
demand on the successor corporation for payment of the stock within 20 days of
the acceptance of articles by the State Department of Assessments and Taxation
of the State of Maryland.
 
     Prohibition on Payment of Greenmail. The Lockheed Bylaws contain a
provision requiring that any purchase by Lockheed or any subsidiary of shares of
any class of equity securities from any beneficial owner of 5% or more of
Lockheed's outstanding capital stock entitled to vote in the election of
directors must first be approved by the affirmative vote of holders of a
majority of outstanding shares of such stock not owned by such person. The
provision is not effective with respect to the purchase, acquisition, redemption
or exchange of such capital stock provided for under the Lockheed Charter or
made as a part of a tender offer or exchange offer by Lockheed to purchase all
securities of the same class made on the same terms to all holders.
 
     The Lockheed Martin Charter contains a provision requiring that any
purchase by Lockheed Martin of shares of stock entitled to vote generally in the
election of directors from a beneficial owner for less than two years of 5% or
more of outstanding shares of such stock at a price per share in excess of the
market price for the shares at such time or certain other transactions with such
stockholder, including a merger or consolidation, or the sale or transfer of
more than $10,000,000 of assets or equity securities, must first be approved by
the affirmative vote of holders of a majority of outstanding shares of such
stock not owned by such stockholder. Under the Lockheed Martin Charter, this
provision may be amended or repealed only by the affirmative vote of holders of
at least 80% of the outstanding shares of such stock.
 
     Dissolution. Under the DGCL, unless the board of directors approves the
proposal to dissolve, dissolution of the corporation must be approved by all
stockholders entitled to vote thereon. Only if the dissolution is initiated by
the board of directors may it be approved by a simple majority of the
corporation's stockholders.
 
     Under the DGCL, the Court of Chancery, upon application by any stockholder,
may appoint a custodian or receiver (a) if the stockholders are so divided that
they have failed to elect successors to directors whose terms have expired, (b)
if the business of the corporation is suffering or is threatened with
irreparable injury because of a deadlock of directors, or (c) if the corporation
has abandoned its business but has not liquidated. Upon the order of the Court
of Chancery or in the event of clause (c) above, the corporation may be
liquidated and its assets distributed.
 
     The MGCL provides for the voluntary dissolution of a corporation by a
resolution adopted by a majority of the corporation's board of directors. A vote
of two-thirds of all votes entitled to be cast on the matter generally is
necessary to approve the dissolution, but, in accordance with the MGCL, the
Lockheed Martin Charter reduces the stockholder vote required to approve a
dissolution to a majority of the votes entitled to be cast on the matter.
 
     The MGCL also provides that stockholders entitled to cast at least 25% of
all the votes entitled to be cast in the election of directors may petition a
court of equity for an involuntary dissolution of the corporation on the ground
that (a) the directors are so divided respecting the management of the
corporation's affairs that the votes required for action by the board cannot be
obtained, or (b) the stockholders are so divided that directors cannot be
elected. Any stockholder entitled to vote in the election of directors of a
Maryland corporation, however, may petition a court of equity to dissolve the
corporation on the ground that (a) the stockholders are so divided that they
have failed, for a period which includes at least two consecutive annual meeting
dates, to elect successors to directors whose terms would have expired on the
election and qualification of their successors, or (b) the acts of the directors
or those in control of the corporation are illegal, oppressive or fraudulent.
 
                                       71
<PAGE>   77
 
     Dividends. The DGCL permits a corporation to declare and pay dividends out
of surplus or, if there is no surplus, out of net profits for the fiscal year in
which the dividend is declared and/or for the preceding fiscal year as long as
the amount of capital of the corporation following the declaration and payment
of the dividend is not less than the aggregate amount of the capital represented
by the issued and outstanding stock of all classes having a preference upon the
distribution of assets. In addition, the DGCL generally provides that a
corporation may redeem or repurchase its shares only if such redemption or
repurchase would not impair the capital of the corporation or if it repurchases
shares having a preference upon the distribution of any of its assets that it
retires such shares upon acquisition (and provided, that after any reduction in
capital made in connection with such retirement of shares, the corporation's
remaining assets are sufficient to pay any debts not otherwise provided for).
 
     The MGCL permits a corporation to make a distribution, including dividends,
redemptions or stock repurchases, unless prohibited by its charter or if
following such distribution, the corporation would not be able to pay its debts
in the ordinary course as they become due or the corporation's total assets
would be less than the sum of its liabilities and, unless the charter provides
otherwise, senior liquidation preferences. For purposes of determining whether a
distribution is lawful, the corporation's assets may be based upon fair value or
any other method of valuation that is reasonable under the circumstances.
 
     Right to Examine Stockholder List. In compliance with the requirements of
the DGCL, the Lockheed Bylaws provide that stockholders have a right for a
period of ten days prior to any stockholder meeting and during such meeting, to
examine a list of stockholders of Lockheed, arranged in alphabetical order and
showing the address and the number of shares held by such stockholder, for any
purpose germane to such meeting. Further, under the DGCL, any stockholder,
following a written request, has the right to inspect the corporation's books
and records, including the stockholder list, during usual business hours for a
proper purpose.
 
     Under the MGCL, any one or more persons who for at least six months have
been the record holders of at least 5% of any class of stock are entitled to
inspect and copy (among other things) the corporation's stock ledger and if the
corporation does not maintain its stock ledger at its principal place of
business, to request in writing a stockholder list. Following such request, the
corporation has 20 days to produce a stockholder list with names, addresses and
number of shares owned. In addition, under the Lockheed Martin Bylaws, the
Secretary of the corporation must furnish a stockholder list at each meeting.
 
     Interested Director Transactions. Under both the DGCL and the MGCL, certain
contracts or transactions in which one or more of a corporation's directors has
an interest are not void or voidable because of such interest provided that
certain conditions are met. Under the DGCL and the MGCL, any such contract or
transaction may be ratified by the stockholders (as set forth below) or a
majority of disinterested members of the board of directors or a committee
thereof if (a) the material facts are disclosed or known thereto, or (b) the
contract or transaction was fair (and under the MGCL, reasonable) to the
corporation at the time it was approved. Under the DGCL, any ratification of
such a contract or transaction by the stockholders must be made by a majority of
all stockholders in good faith. Under the MGCL, such ratification must be made
by a majority of the disinterested stockholders.
 
     Preemptive Rights. Under the DGCL, stockholders have no preemptive rights
unless such rights are provided for in the certificate of incorporation. Under
the MGCL, subject to several statutory exceptions and the power of the
corporation to deny preemptive rights in its charter, stockholders have
preemptive rights. The Lockheed Martin Charter denies preemptive rights to
holders of any class of stock.
 
                  DESCRIPTION OF LOCKHEED MARTIN CAPITAL STOCK
 
     The summary of the terms of the stock of Lockheed Martin set forth below
does not purport to be complete and is subject to and qualified in its entirety
by reference to the Lockheed Martin Charter and the Lockheed Martin Bylaws.
Copies of the Lockheed Martin Charter and the Lockheed Martin Bylaws, in
substantially the forms to be adopted prior to the consummation of the
Combination, are attached as
 
                                       72
<PAGE>   78
 
Exhibits A and B, respectively, to the Reorganization Agreement which is
attached to this Joint Proxy Statement/Prospectus as Appendix I.
 
AUTHORIZED CAPITAL STOCK
 
     Under the Lockheed Martin Charter, the total number of shares of all
classes of stock that Lockheed Martin has authority to issue is 820,000,000
shares, of which 750,000,000 are shares of Lockheed Martin Common Stock,
20,000,000 are shares of Lockheed Martin Series A Preferred Stock, and
50,000,000 are shares of Lockheed Martin Series Preferred Stock.
 
     The additional shares of authorized stock available for issuance by
Lockheed Martin might be issued at such times and under such circumstances as to
have a dilutive effect on earnings per share and on the equity ownership of the
holders of Lockheed Martin Common Stock. The ability of the Lockheed Martin
Board to issue additional shares of stock could enhance the Lockheed Martin
Board's ability to negotiate on behalf of the stockholders in a takeover
situation and also could be used by the Lockheed Martin Board to make a change
in control more difficult, thereby denying stockholders the potential to sell
their shares at a premium and entrenching current management.
 
COMMON STOCK
 
     Subject to any preferential rights of the Lockheed Martin Series A
Preferred Stock or any series of Lockheed Martin Series Preferred Stock, holders
of shares of Lockheed Martin Common Stock will be entitled to receive dividends
on such stock out of assets legally available for distribution when, as and if
authorized and declared by the Lockheed Martin Board and to share ratably in the
assets of Lockheed Martin legally available for distribution to its stockholders
in the event of its liquidation, dissolution or winding-up. Lockheed Martin will
not be able to pay any dividend or make any distribution of assets on shares of
Lockheed Martin Common Stock until cumulative dividends on shares of the
Lockheed Martin Series A Preferred Stock and on any other shares of Lockheed
Martin Series Preferred Stock then outstanding with dividend or distribution
rights senior to the Lockheed Martin Common Stock have been paid. See "THE
REORGANIZATION AGREEMENT -- Lockheed Martin Following Combination" with respect
to the anticipated initial quarterly dividend on the Lockheed Martin Common
Stock.
 
     Holders of Lockheed Martin Common Stock will be entitled to one vote per
share on all matters voted on generally by the stockholders, including the
election of directors, and, except as otherwise required by law or except as
provided with respect to the Lockheed Martin Series A Preferred Stock or any
series of Lockheed Martin Series Preferred Stock, the holders of such shares
will possess all voting power. See "-- Series A Preferred Stock -- Voting
Rights." The Lockheed Martin Charter does not provide for cumulative voting for
the election of directors except as described under "-- Certain Antitakeover
Effects of Lockheed Martin Charter and Bylaws and Maryland Law -- Prohibition on
Payment of Greenmail; Cumulative Voting for Directors." Thus, the holders of
more than one-half of the outstanding shares of Lockheed Martin Common Stock
generally will be able to elect all the directors of Lockheed Martin then
standing for election and holders of the remaining shares will not be able to
elect any director.
 
     The shares of Lockheed Martin Common Stock, when issued to holders of
outstanding shares of Lockheed Common Stock or Martin Marietta Common Stock in
connection with the Combination, or when issued upon conversion of shares of the
Lockheed Martin Series A Preferred Stock, will be validly issued, fully paid and
non-assessable.
 
     Holders of Lockheed Martin Common Stock will have no preferences,
preemptive, conversion, or exchange rights.
 
SERIES A PREFERRED STOCK
 
     The shares of Lockheed Martin Series A Preferred Stock, when issued to the
holder of the outstanding shares of Martin Marietta Series A Preferred Stock in
connection with the Combination, will be validly issued, fully paid and
non-assessable.
 
                                       73
<PAGE>   79
 
  Designation and Amount
 
     The Lockheed Martin Series A Preferred Stock will have a par value of $1.00
per share and a liquidation preference of $50 per share, plus accrued and unpaid
dividends. The authorized number of shares of Lockheed Martin Series A Preferred
Stock is 20,000,000. The terms of the Lockheed Martin Marietta Series A
Preferred Stock are essentially the same as those of the Martin Marietta Series
A Preferred Stock issued to GE on April 2, 1993.
 
  Rank
 
     With respect to dividend rights and rights on liquidation, dissolution and
winding up, the Lockheed Martin Series A Preferred Stock will rank senior to all
other classes of stock of Lockheed Martin except those classes of preferred
stock expressly designated as ranking on a parity with the Lockheed Martin
Series A Preferred Stock.
 
  Dividends
 
     Preferential cash dividends at the per share rate of $.75 per quarter will
accrue (whether or not declared and whether or not funds are legally available
for payment) from the last quarterly dividend payment date on which dividends
have been paid with respect to the Martin Marietta Series A Preferred Stock,
will be cumulative and will compound quarterly, to the extent they are unpaid,
at the rate of 6% per annum computed on the basis of a 360-day year of twelve
30-day months. Holders of shares of Lockheed Martin Series A Preferred Stock are
not entitled to any other dividends.
 
  Redemption
 
     Upon the giving of specified notice, on or after April 2, 1998, Lockheed
Martin, at its option, will be entitled to redeem any or all shares of Lockheed
Martin Series A Preferred Stock, at a redemption price of $50 per share, plus an
amount equal to accrued and unpaid dividends thereon to and including the date
of redemption (the "Redemption Price"), but only if the Average Closing Price
(as described below) of Lockheed Martin Common Stock (calculated as of the
record date fixed for notifying holders of such redemption) equals or exceeds
the applicable percentage of the Conversion Price (as described below) set forth
opposite the date that occurs on or that immediately preceded such record date:

</TABLE>
 
     The "Average Closing Price" per share of Lockheed Martin Common Stock on
any day shall be deemed to be the average of the closing prices for Lockheed
Martin Common Stock for the 20 consecutive trading days commencing 30 trading
days before the day in question, with each day's closing sale price being the
reported last sale price regular way or, in case no such reported sale takes
place on such day, the average of the reported closing bid and asking prices, in
either case on the NYSE.
 
     In lieu of paying the Redemption Price in cash, Lockheed Martin may, at its
sole option, pay such Redemption Price in shares of Lockheed Martin Common
Stock. The number of shares of Lockheed Martin Common Stock issuable in lieu of
a cash payment of the Redemption Price will be the number of fully paid and
nonassessable shares of Lockheed Martin Common Stock as will have an aggregate
Average Closing Price as of the redemption date equal to the aggregate
liquidation preference of the shares of Lockheed Martin Series A Preferred Stock
being redeemed.

<PAGE>   80
 
     Within 15 days of its receipt of notice of a redemption payable in shares
of Lockheed Martin Common Stock, each holder of Lockheed Martin Series A
Preferred Stock will have the right to elect not to retain such Lockheed Martin
Common Stock and to request a Backstop Registration (as described below) of some
or all of the shares of Lockheed Martin Common Stock to be received in the
redemption (the "Redemption Common Stock"). A holder's failure to timely so
request Backstop Registration will be deemed to be an election by the holder to
retain such Lockheed Martin Common Stock.
 
     A Backstop Registration for shares of Lockheed Martin Common Stock issued
in lieu of a redemption in cash will be conducted substantially in the manner
described under "STANDSTILL AGREEMENT -- Special Liquidity
Provisions -- Backstop Registration."
 
     When the Backstop Registration has been completed, the net proceeds thereof
will be distributed to the holders who requested the Backstop Registration pro
rata in respect of their interests in the Lockheed Martin Common Stock subject
to the Backstop Registration. Any such Backstop Registration not consummated
within six months will be deemed to have been abandoned. To the extent the net
proceeds per share from such Backstop Registration are less than the sum of the
Redemption Price and the interest on such Redemption Price (at an annual rate
published by the Board of Governors of the Federal Reserve System for U.S.
Treasury Bonds maturing 10 years from the applicable redemption date) from the
applicable redemption date to and including the date of payment in respect of a
requesting holder's redeemed shares of Lockheed Martin Series A Preferred Stock,
Lockheed Martin will pay to the requesting holder an amount in cash equal to the
applicable difference.
 
  Conversion Rights
 
     The holders of shares of Lockheed Martin Series A Preferred Stock will have
the right, at their option, to convert each share into such number of fully paid
and nonassessable shares of Lockheed Martin Common Stock as is determined by
dividing $50 by the Conversion Price (as defined below) in effect at the time of
conversion. As of the Merger Date, the "Conversion Price" for the Lockheed
Martin Series A Preferred Stock will be $34.5525. The Conversion Price will be
subject to anti-dilution adjustments as described below under "Anti-Dilution
Provisions."
 
  Anti-Dilution Provisions
 
     The number of shares of stock into which each share of Lockheed Martin
Series A Preferred Stock is convertible will be subject to certain anti-dilution
adjustments upon the occurrence of certain events such as (i) stock dividends or
other distributions on the Lockheed Martin Common Stock or other stock of
Lockheed Martin payable in Lockheed Martin Common Stock, (ii) stock splits,
reverse stock splits, share exchanges or reclassifications affecting the
Lockheed Martin Common Stock, (iii) certain issuances of Lockheed Martin Common
Stock (or rights, warrants or securities convertible or exchangeable into
Lockheed Martin Common Stock) at a price per share (or having a conversion or
exercise price per share) less than the Average Closing Price of Lockheed Martin
Common Stock on the date of issuance, (iv) distributions to holders of Lockheed
Martin Common Stock or any other class of stock of Lockheed Martin of evidences
of indebtedness or assets of Lockheed Martin (excluding any regular quarterly
dividend of Lockheed Martin paid in cash out of the consolidated earnings or
consolidated retained earnings of Lockheed Martin in an amount not exceeding
125% of the average of the four regular quarterly dividends paid by Lockheed
Martin for the immediately preceding four quarters (including for this purpose
dividends paid by Martin Marietta prior to the Merger Date)), and (v)
repurchases, by Lockheed Martin or any of its subsidiaries, by self tender offer
or otherwise, of any shares of Lockheed Martin Common Stock at a weighted
average purchase price in excess of the Average Closing Price immediately prior
to such repurchase.
 
  Voting Rights
 
     Except as otherwise provided below or as required by law, the holders of
shares of Lockheed Martin Series A Preferred Stock will not be entitled to vote
on any matter on which the holders of any voting securities of Lockheed Martin
will be entitled to vote.
 
                                       75
<PAGE>   81
 
     Upon a default with respect to Lockheed Martin's senior bank facility (if
any) or any successor thereto or replacement thereof (as amended from time to
time, the "Senior Bank Facility") that is not substantially cured within six
months from the declaration thereof pursuant to the Senior Bank Facility (but
without regard to any waivers granted by the lenders under such Senior Bank
Facility) (a "Bank Debt Default"), the holders of the Lockheed Martin Series A
Preferred Stock, voting as a separate class, will be entitled to elect the
smallest number of directors of the Lockheed Martin Board that shall constitute
no less than 25% of the authorized number of directors of the Lockheed Martin
Board until the Bank Debt Default is cured, or until GE is no longer entitled to
designate any directors of Lockheed Martin pursuant to the Standstill Agreement,
whichever first occurs. Following expiration of such rights of GE under the
Standstill Agreement, the holders of the Lockheed Martin Series A Preferred
Stock will have only the voting rights described below and as otherwise required
by law. See "THE STANDSTILL AGREEMENT -- Voting."
 
     In the event that dividends payable on the Lockheed Martin Series A
Preferred Stock are in arrears for six quarters (whether or not consecutive)(a
"Preferred Dividend Default") and if the holders of the Lockheed Martin Series A
Preferred Stock are not then represented on the Lockheed Martin Board by
directors elected as a result of a Bank Debt Default, until the Preferred
Dividend Default is cured, a majority in interest of the holders of Lockheed
Martin Series A Preferred Stock, voting separately as a class with holders of
shares of any other class of preferred stock upon which like voting rights have
been conferred, will be entitled to elect two additional directors of Lockheed
Martin.
 
     In the event of any merger, consolidation, business combination or share
exchange involving Lockheed Martin or any sale, lease or conveyance of all or
substantially all of the assets of Lockheed Martin upon which the holders of
Lockheed Martin Common Stock are entitled to vote, the holder of each share of
Lockheed Martin Series A Preferred Stock will be entitled to vote together with
the holders of shares of Lockheed Martin Common Stock and to cast the number of
votes equal to the number of shares of Lockheed Martin Common Stock into which
such shares of Lockheed Martin Series A Preferred Stock are then convertible;
provided, however, that the holders of the Lockheed Martin Series A Preferred
Stock will not be entitled to vote upon acquisitions which, within any 12-month
period, do not (i) involve greater than an aggregate of $25 million of
transaction value (including assumed liabilities, whether contingent or not) or
(ii) adversely affect the economic or legal position of the holders of Lockheed
Martin Series A Preferred Stock or their rights, preferences, privileges or
voting powers.
 
     So long as any shares of the Lockheed Martin Series A Preferred Stock
remain outstanding, the consent of the holders of at least 66 2/3% of the shares
of Lockheed Martin Series A Preferred Stock then outstanding (voting separately
as a class) given in person or by proxy, at any special or annual meeting called
for such purpose, or by written consent as permitted by law and the Lockheed
Martin Charter and Lockheed Martin Bylaws, will be necessary to amend, alter or
repeal any of the provisions of the Lockheed Martin Charter which would
adversely affect any right, preference, privilege, or voting power of Lockheed
Martin Series A Preferred Stock or of the holders thereof; provided, however,
that any such amendment, alteration or repeal that would authorize, create or
issue any additional shares of preferred stock or any other shares of stock
(whether or not already authorized) ranking on a parity with or junior to the
Lockheed Martin Series A Preferred Stock as to dividends and on the distribution
of assets upon liquidation, dissolution or winding up, will be deemed not to
materially and adversely affect such rights, preferences, privileges or voting
powers.
 
  Liquidation Rights
 
     Subject to the rights of holders of Lockheed Martin Series Preferred Stock
ranking on a parity with the Lockheed Martin Series A Preferred Stock, upon any
dissolution, liquidation or winding up of the affairs of Lockheed Martin,
whether voluntary or involuntary (collectively, a "Liquidation"), the holders of
shares of Lockheed Martin Series A Preferred Stock will be entitled to receive
liquidating distributions in the amount of $50 per share, plus an amount equal
to all dividends accrued and unpaid thereon to the date of Liquidation, before
any distribution or payment is made to holders of Lockheed Martin Common Stock
or on any other class of stock of Lockheed Martin ranking junior as to dividends
or assets distributable upon Liquidation to the holders of shares of Lockheed
Martin Series A Preferred Stock. After the payment to the holders of the
Lockheed Martin Series A Preferred Stock of the full preferential amounts
described above, the holders of the
 
                                       76
<PAGE>   82
 
Lockheed Martin Series A Preferred Stock will not be entitled to any further
participation in any distribution or payment by Lockheed Martin.
 
     Neither the merger or consolidation of Lockheed Martin into or with any
other corporation, nor the merger or consolidation of any other corporation into
or with Lockheed Martin, nor a sale, transfer or lease of all or any part of the
assets of Lockheed Martin, will, without further corporate action, be deemed to
be a Liquidation.
 
  Tax Provisions
 
     Lockheed Martin will treat the Lockheed Martin Series A Preferred Stock as
equity (not debt) for all federal, state, local and other tax purposes. Lockheed
Martin will use its reasonable best efforts to ensure that it has adequate
earnings and profits, within the meaning of Section 312 of the Code, or any
successor provision, to ensure that all dividend distributions on the Lockheed
Martin Series A Preferred Stock and all distributions in redemption of the
Lockheed Martin Series A Preferred Stock that are treated as distributions with
respect to stock under Section 302(d) of the Code (or any successor provisions)
will be treated as dividends within the meaning of Section 316 of the Code (or
any successor provision); provided that such reasonable best efforts do not
require Lockheed Martin to incur any material out-of-pocket costs unless such
costs are reimbursed by GE.
 
  Certain Potential Antitakeover Effects of the Lockheed Martin Series A
Preferred Stock
 
     Although the issuance of shares of Lockheed Martin Series A Preferred Stock
to GE in connection with the Combination is not intended as an antitakeover
device, it should be noted that such issuance, and the issuance of Lockheed
Martin Common Stock or other securities into which the Lockheed Martin Series A
Preferred Stock is convertible or exchangeable and the provisions of the
Standstill Agreement, may have certain antitakeover effects. It may discourage
or render more difficult a merger, tender offer or proxy contest involving
Lockheed Martin or deter a third party from seeking to acquire control of
Lockheed Martin. See "THE STANDSTILL AGREEMENT -- Voting" and "-- Certain
Antitakeover Effects of Lockheed Martin Charter and Bylaws and Maryland Law."
 
SERIES PREFERRED STOCK
 
     The Lockheed Martin Board is authorized to issue shares of Lockheed Martin
Series Preferred Stock, in one or more series or classes, and to fix for each
such series or class the preferences, conversion or other rights, voting powers,
restrictions, limitations as to dividends, qualifications, or terms or
conditions of redemption, as are permitted by Maryland law. The Lockheed Martin
Board could authorize the issuance of shares of Lockheed Martin Series Preferred
Stock with terms and conditions which could discourage a takeover or other
transaction that holders of some or a majority of shares of Lockheed Martin
Common Stock might believe to be in their best interests or in which such
holders might receive a premium for their shares of stock over the then market
price of such shares. As of the date hereof, no shares of Lockheed Martin Series
Preferred Stock are outstanding and the Lockheed Martin Board has no present
intent to issue any shares of Lockheed Martin Series Preferred Stock after the
Merger Date.
 
PREEMPTIVE RIGHTS
 
     No holder of any shares of any class of stock of Lockheed Martin will have
any preemptive or preferential right to acquire or subscribe for any unissued
shares of any class of stock or any authorized securities convertible into or
carrying any right, option or warrant to subscribe for or acquire shares of any
class of stock.
 
TRANSFER AGENT AND REGISTRAR
 
     The principal transfer agent and registrar for Lockheed Martin Common Stock
will be First Chicago Trust Company of New York.

CERTAIN ANTITAKEOVER EFFECTS OF LOCKHEED MARTIN CHARTER AND BYLAWS AND MARYLAND
LAW
 
  General
 
     Certain provisions of the Lockheed Martin Charter and Bylaws may have the
effect of impeding the acquisition of control of Lockheed Martin by means of a
tender offer, a proxy fight, open market purchases or otherwise in a transaction
not approved by the Lockheed Martin Board.
 
     The provisions of the Lockheed Martin Charter and Bylaws described below
are designed to reduce the vulnerability of Lockheed Martin to an unsolicited
proposal for the restructuring or sale of all or substantially all of the assets
of Lockheed Martin or an unsolicited takeover attempt which does not provide
that all of Lockheed Martin's outstanding shares will be acquired or which is
otherwise unfair to Lockheed Martin stockholders. The summary of such provisions
set forth below does not purport to be complete and is subject to and qualified
in its entirety by reference to the Lockheed Martin Charter and Bylaws.
 
     The Lockheed Martin Board is not presently aware of any attempt to bring
about a change in control of Lockheed Martin and has no present intention to
introduce additional measures which might have an anti-takeover effect. The
Lockheed Martin Board, however, expressly reserves the right to introduce such
measures in the future.
 
  Removal of Directors
 
     The Lockheed Martin Charter provides that a director may be removed by the
stockholders only for cause and only by the affirmative vote of at least 80% of
the votes entitled to be cast in the election of directors. This provision
precludes stockholders from removing incumbent directors and filling the
vacancies created by such removal with their own nominees except upon a
substantial affirmative vote. This provision may be amended or repealed only by
the affirmative vote of at least 80% of the votes entitled to be cast in the
election of directors.
 
  Business Combinations
 
     Under the MGCL, certain "business combinations" (including a merger,
consolidation, share exchange, or, in certain circumstances, an asset transfer
or issuance or reclassification of equity securities) between a Maryland
corporation and (i) any person who beneficially owns 10% or more of the voting
power of the corporation's shares, (ii) an affiliate of such corporation who, at
any time within the two-year period prior to the date in question, was the
beneficial owner of 10% or more of the voting power of the then-outstanding
voting stock of the corporation (in either case, an "interested stockholder"),
or (iii) any affiliate of an interested stockholder, are prohibited for five
years after the most recent date on which the interested stockholder became an
interested stockholder, and thereafter must be recommended by the board of
directors of the Maryland corporation and approved by the affirmative vote of at
least (a) 80% of the votes entitled to be cast by holders of its outstanding
voting shares, and (b) two-thirds of the votes entitled to be cast by holders of
such outstanding voting shares, other than shares held by the interested
stockholder with whom the business combination is to be effected; unless, among
other things, the corporation's stockholders receive a minimum price (as defined
in the MGCL) for their shares and the consideration is received in cash or in
the same form as previously paid by the interested stockholder for its shares.
These provisions of the MGCL do not apply to business combinations that are
approved or exempted by the board of directors of the corporation prior to the
time that the interested stockholder becomes an interested stockholder.
 
     Lockheed Martin will generally be governed by the MGCL's business
combinations statute. However, the Lockheed Martin Board has exempted any
business combination with GE from its application.
 
     In addition to the MGCL requirements, the Lockheed Martin Charter also
contains a provision requiring that any business combination between Lockheed
Martin and a Related Person must be approved by 80% of the outstanding shares of
Voting Stock and by two-thirds of the outstanding shares of Voting Stock not
owned by the Related Person. This provision does not apply to a business
combination approved by a two-thirds vote of the directors in office prior to
the time a Related Person becomes a Related Person (and certain other directors
designated from time to time as "Continuing Directors") or if the consideration
received by the
 
                                       78
<PAGE>   84
 
stockholders other than the Related Person is not less than the highest price
per share paid by the Related Person prior to the business combination and a
proxy statement complying with the regulations of the Exchange Act shall have
been sent to all stockholders. Under the Lockheed Martin Charter, this provision
may be amended only by the same two supermajority votes required for approval of
a business combination. The Lockheed Martin Charter provides that Lockheed and
Martin Marietta and certain of their subsidiaries are not Related Persons for
purposes of this provision.
 
  Control Share Acquisitions
 
     The MGCL provides that "control shares" of a Maryland corporation acquired
in a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast by
stockholders in the election of directors, excluding shares of stock as to which
the acquiring person, officers of the corporation and directors of the
corporation who are employees of the corporation are entitled to exercise or
direct the exercise of the voting power of the shares in the election of
directors. "Control shares" are voting shares of stock which, if aggregated with
all other shares of stock previously acquired by such person, would entitle the
acquiror to exercise voting power in electing directors within one of the
following ranges of voting power: (i) one-fifth or more but less than one-third,
(ii) one-third or more but less than a majority or (iii) a majority of all
voting power. Control shares do not include shares which the acquiring person is
entitled to vote as a result of having previously obtained stockholder approval.
A "control share acquisition" means the acquisition, directly or indirectly, of
control shares, subject to certain exceptions.
 
     A person who has made or proposes to make a control share acquisition, upon
satisfaction of certain conditions (including an undertaking to pay expenses),
may compel the board of directors to call a special meeting of stockholders to
be held within 50 days of demand to consider the voting rights of the shares.
 
     If voting rights are not approved at the meeting or if the acquiror does
not deliver an acquiring person statement as required by the statute, then
subject to certain conditions and limitations, the corporation may redeem any or
all of the control shares, except those for which voting rights have previously
been approved, for fair value determined, without regard to voting rights, as of
the date of the last control share acquisition or of any meeting of stockholders
at which the voting rights of such shares are considered and not approved. If
voting rights for control shares are approved at a stockholders' meeting and the
acquiror becomes entitled to vote a majority of the shares entitled to vote, all
other stockholders may exercise appraisal rights. The fair value of the shares
as determined for purposes of such appraisal rights may not be less than the
highest price per share paid in the control share acquisition, and certain
limitations and restrictions generally applicable to the exercise of appraisal
rights do not apply in the context of a control share acquisition.
 
     The control share acquisition statute does not apply to shares acquired in
a merger, consolidation or share exchange if the corporation is a party to the
transaction or to acquisitions approved or excepted by the charter or the bylaws
of the corporation.
 
     The business combination statute and the control share acquisition statute
could have the effect of discouraging unsolicited offers to acquire Lockheed
Martin and of increasing the difficulty of consummating any such offer.
 
  Prohibition on Payment of Greenmail; Cumulative Voting for Directors
 
     The Lockheed Martin Charter contains a provision requiring that any
purchase by Lockheed Martin of shares of Voting Stock from an Interested
Stockholder (as defined in such provision, any person who has been a beneficial
owner for less than two years of 5% or more of outstanding shares of Voting
Stock) other than pursuant to an offer to holders of all the outstanding shares
of the same class at a price in excess of the market price of the stock on the
day immediately preceding the purchase, must first be approved by the
affirmative vote of holders of a majority of outstanding shares of Voting Stock
not owned by such Interested Stockholder. Under the Lockheed Martin Charter,
this provision may be amended or repealed only by the affirmative vote of
holders of at least 80% of the outstanding shares of Voting Stock.
 
                                       79
<PAGE>   85
 
     The Lockheed Martin Charter further provides that if any person (other than
Lockheed Martin or certain of its affiliates) beneficially owns Voting Stock
representing 40% or more of the votes entitled to be cast by all the holders of
outstanding shares of Voting Stock, (i) the directors of Lockheed Martin will be
elected by cumulative voting, and (ii) one or more candidates may be nominated
by certain disinterested directors, or by any beneficial owner of Voting Stock
having an aggregate market price of $250,000 or more.
 
  Advance Notice of Director Nominations and New Business
 
     The Lockheed Martin Bylaws provide that (i) with respect to annual meetings
of stockholders, nominations of persons for election to the Lockheed Martin
Board and the proposal of business to be considered by stockholders may be made
only (a) pursuant to Lockheed Martin's notice of the meeting, (b) by or at the
direction of the Lockheed Martin Board or (c) by a stockholder who has complied
with the advance notice procedures set forth in the Lockheed Martin Bylaws and
is entitled to vote at the meeting; and (ii) with respect to special meetings of
stockholders, only the business specified in Lockheed Martin's notice of meeting
may be brought before the meeting. Nominations of persons for election to the
Lockheed Martin Board may be made at a special meeting of stockholders at which
directors are to be elected pursuant to Lockheed Martin's notice of meeting only
(i) by or at the direction of the Lockheed Martin Board, or (ii) by a
stockholder who has complied with the advance notice provisions set forth in the
Lockheed Martin Bylaws and is entitled to vote at the meeting.
 
  Right to Examine Stockholder List
 
     Under the MGCL, any one or more persons who for at least six months have
been the record holders of at least 5% of any class of stock are entitled to
inspect and copy the corporation's stock ledger and if the corporation does not
maintain its stock ledger at its principal place of business, to request in
writing a stockholder list. See "COMPARISON OF STOCKHOLDERS'
RIGHTS -- Comparison of Stockholder Rights with Respect to Lockheed Martin and
Lockheed -- Right to Examine Stockholder List."
 
  Effect of Certain Provisions
 
     The provisions in the Lockheed Martin Charter on removal of directors,
payment of greenmail, cumulative voting for directors in the event that a
stockholder owns 40% or more of the Voting Stock, and the business combinations,
control share acquisition and right to examine stockholder list provisions of
MGCL, and the advance notice provisions of the Lockheed Martin Bylaws, could
have the effect of delaying, deterring or preventing a change in control of
Lockheed Martin. In addition, the Lockheed Martin Omnibus Plan contains
provisions applicable to a change of control situation. See "LOCKHEED MARTIN
1995 OMNIBUS PERFORMANCE AWARD PLAN."

* GE designees to the Lockheed Martin Board. See "THE STANDSTILL
  AGREEMENT -- Board Representation."
 
     For information concerning the interests of the directors of Lockheed
Martin in the Combination, see "THE COMBINATION -- Interests of Certain Persons
in the Combination."
 
COMPENSATION OF DIRECTORS
 
     Directors, other than employees of Lockheed Martin, will initially receive
$35,000 annually for service on the Lockheed Martin Board and $1,000 per meeting
attended, including the annual meeting of stockholders of Lockheed Martin. A
total of $10,000 of the $35,000 will be paid annually in the form of share
credits based on the value of Lockheed Martin Common Stock, subject to approval
of the Directors Plan Proposal. Directors will also be reimbursed for expenses
incurred in connection with attendance at Lockheed Martin Board and committee
meetings.
 
     The Lockheed Martin Board will have five standing committees: Audit and
Ethics, Compensation, Executive, Finance and Nominating. Non-employee directors
of Lockheed Martin will initially receive $5,000 annually for each committee on
which they serve and $1,000 per committee meeting attended. Additionally,
committee chairs, if held by non-employee directors, will receive the following
compensation: initially, Chairmen of the Audit and Ethics, Compensation,
Executive, and Finance Committees will receive $4,000 additional compensation
per year, and the Chairman of the Nominating Committee will receive $2,000
additional compensation per year. See "-- Committees of the Board of Directors."
 
     It is anticipated that a deferred compensation plan will be implemented for
non-employee directors, pursuant to which they will be entitled to defer all or
a portion of their cash compensation for service as a director and committee
member.
 
                                       86
<PAGE>   92
 
     The mandatory retirement age for directors is 70. However, in order to
assist Lockheed Martin in the transition period following the Combination, Mr.
Kitchen and Mr. Potter will be eligible to serve on the Lockheed Martin Board
until the annual meetings of stockholders in 1996 and 1997, respectively, at
which time each will be 72 years of age. It is expected that following
retirement from the Lockheed Martin Board non-employee directors will be paid an
annual retirement benefit equal to the amount of the annual fee (including both
the cash and stock portions thereof) in effect on the date the director leaves
the Lockheed Martin Board. These amounts will be paid in cash in regular
installments for a period equal to the number of years that the director serves
on the Lockheed Martin Board as a non-employee director. If the director retires
at the mandatory retirement age after satisfying a vesting period to be
determined, the benefit will be paid annually for life.
 
     Lockheed Martin also intends to implement a financial counseling program
which will provide reimbursement to directors for tax and financial planning and
tax preparation services and for which Lockheed Martin will pay a maximum of
$6,000 annually per participant. In addition, for each non-employee director
Lockheed Martin intends to provide a $100,000 death benefit and provide $500,000
coverage for death or dismemberment resulting from an accident while traveling
on company business.
 
     In the interests of promoting giving to charitable institutions and
tax-exempt educational institutions, Lockheed Martin will maintain a plan which
will allow each director (except continuing directors from Martin Marietta who
have a comparable benefit through a substantially similar plan) to recommend one
or more charitable organizations that would receive, in the aggregate, up to $1
million, such contribution to be payable to the designated institution(s) upon a
director's death. Lockheed Martin expects to fund the program through the
purchase of insurance on the directors' lives. Directors will not receive any
economic benefit from the program because the insurance proceeds and charitable
deductions will accrue solely to Lockheed Martin.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
     Pursuant to the Reorganization Agreement, Martin Marietta and Lockheed have
agreed that membership on the major committees of the Lockheed Martin Board will
initially consist of an equal number of designees of Martin Marietta and
Lockheed. The members of such committees will be determined by the Lockheed
Martin Board prior to the Combination.

     It is expected that Mr. Tellep will be Chief Executive Officer of Lockheed
Martin through 1995 and Chairman of the Lockheed Martin Board through 1996. It
is also expected that Mr. Augustine will be President of Lockheed Martin through
1995, become President and Chief Executive Officer at the end of 1995 and
Chairman of the Board and Chief Executive Officer at the end of 1996.
 
     For information concerning the interests of certain of the above-named
individuals in the Combination, see "THE COMBINATION -- Interests of Certain
Persons in the Combination."
 
COMPENSATION OF EXECUTIVE OFFICERS
 
     Lockheed Martin has not yet paid any compensation to its Chief Executive
Officer or any of its other executive officers and the form and amount of such
compensation has not yet been determined. The Lockheed Martin Board will rely on
its Compensation Committee composed of non-employee Board members to recommend
the form and amount of compensation to be paid to Lockheed Martin's executive
officers.
 
     It is anticipated that, when the Compensation Committee meets to determine
such compensation, which meeting is not expected to occur until after the Merger
Date, the Committee will generally adhere to compensation policies which reflect
the belief that (i) Lockheed Martin must attract and retain individuals of
outstanding ability and motivate and reward such individuals for sustained
performance, (ii) a substantial portion of an executive's compensation should be
at risk based upon that executive's performance and that of the corporation, and
(iii) within these parameters, levels of compensation should generally be in
line with that offered by comparable corporations. Hewitt Associates has been
engaged to advise the Compensation Committee as to the compensation paid by
companies of a size and complexity generally comparable to Lockheed Martin. In
addition, each of Lockheed and Martin Marietta has asked three of its current
directors to work with Hewitt Associates so as to be prepared to offer advice to
the Compensation Committee shortly following the Merger Date. On an ongoing
basis the type and amount of compensation to be paid by Lockheed
 
                                       88
<PAGE>   94
 
Martin to its officers will be entirely discretionary and within the subjective
judgment of the Compensation Committee.
 
     For information concerning the compensation paid to the Chief Executive
Officers and the other four most highly compensated executive officers of each
of Lockheed and Martin Marietta for the 1993 fiscal year, see the 1994 Proxy
Statements for Lockheed and Martin Marietta, the relevant portions of which are
incorporated by reference into the Lockheed Form 10-K and the Martin Marietta
Form 10-K, respectively. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."

     Directors and Executive Officers. The following table sets forth the number
of shares of Lockheed Common Stock beneficially owned, as of December 31, 1994
unless otherwise indicated, and the equivalent number of shares of Lockheed
Martin Common Stock assuming consummation of the Combination, by each current
director, the Chief Executive Officer and the four other most highly compensated
executive officers of Lockheed and for all current directors and executive
officers of Lockheed as a group. The number of shares shown for each director
and each of the named executive officers represent less than 1 percent of the
shares of Lockheed Common Stock outstanding and Lockheed Martin Common Stock
expected to be outstanding upon consummation of the Combination. The number of
shares shown for all directors and executive officers as a group represented
approximately 2.7 percent of the Lockheed Common Stock outstanding. Unless
otherwise indicated, and except as such powers may be shared with their spouses,
the individuals named below have sole voting and investment power with respect
to the shares indicated below.

     consummation of the Combination).
 
                            THE STANDSTILL AGREEMENT
 
     In connection with the combination of the aerospace business of GE and
certain other businesses of GE with the businesses of Martin Marietta
Technologies, Inc., on April 2, 1993, Martin Marietta issued to GE 20,000,000
shares of Martin Marietta Series A Preferred Stock and entered into a standstill
agreement with GE. On the Merger Date, as a result of the Atlantic Sub Merger,
GE's shares of Martin Marietta Series A Preferred Stock will be converted into
Lockheed Martin Series A Preferred Stock. In anticipation of that event, Martin
Marietta, Lockheed Martin and GE entered into an agreement dated August 29, 1994
as amended as of November 30, 1994 (the "Reconfiguration Agreement") that, among
other things, modified the standstill agreement with GE to anticipate the
conversion of shares from Martin Marietta Series A Preferred Stock to Lockheed
Martin Series A Preferred Stock.
 
     The following description is a summary of the standstill agreement, as
modified by the Reconfiguration Agreement (as such agreement would be in effect
on the Merger Date, the "Standstill Agreement"), and is qualified in its
entirety by reference to the provisions of the Standstill Agreement and
Reconfiguration Agreement, which are incorporated by reference herein and
included as exhibits to the Registration Statement of which this Joint Proxy
Statement/Prospectus is a part.
 
TERM
 
     The Standstill Agreement will continue in effect until the date on which GE
beneficially owns voting securities of Lockheed Martin, the voting power of
which in the general election of directors of Lockheed Martin represents less
than two and one-half percent of the total combined voting power in the general
election of directors of Lockheed Martin of all the voting securities of
Lockheed Martin then outstanding; provided, however, that the special liquidity
provisions described below will survive such termination. See "-- Special
Liquidity Provisions." For purposes of the Standstill Agreement, the term
"voting securities" includes the Lockheed Martin Series A Preferred Stock.
 
STANDSTILL PROVISIONS
 
     During the term of the Standstill Agreement, except as otherwise expressly
provided therein, GE will not, and will cause each of its affiliates and
associates not to, singly or as part of a group (as defined in Section 13(d)(3)
of the Exchange Act), directly or indirectly (i) acquire, offer to acquire, or
agree to acquire, by purchase, gift or otherwise, any of Lockheed Martin's
voting securities, (ii) make, or in any way participate in any "solicitation" of
"proxies" to vote (as such terms are defined in Rule 14a-1 under the Exchange
Act), solicit any consent or communicate with or seek to advise or influence any
person or entity with respect to the voting of, any of Lockheed Martin's voting
securities or become a "participant" in any "election contest" (as such terms
are defined or used in Rule 14a-11 under the Exchange Act) with respect to
Lockheed Martin, (iii) form, join or encourage the formation of, any "person"
within the meaning of Section 13(d)(3) of the Exchange Act with respect to any
of Lockheed Martin's voting securities (except an arrangement solely among GE
and any of its wholly owned subsidiaries), (iv) deposit any Lockheed Martin
voting securities into a voting trust or subject any such voting securities to
any arrangement or agreement with respect to the voting thereof (except for such
an arrangement solely among GE and any of its wholly owned subsidiaries), (v)
initiate, propose or otherwise solicit stockholders for the approval of one or
more stockholder proposals with respect to Lockheed Martin as described in Rule
14a-8 under the Exchange Act, or induce or attempt to induce any other person to
initiate any stockholder proposal, (vi) seek election to or seek to place a
representative on the Lockheed Martin Board or, except with the approval of
management of Lockheed Martin, seek the removal of any member of the Lockheed
Martin Board, (vii) except with the approval of management of Lockheed Martin,
call or seek to have called any meeting of the stockholders of Lockheed Martin,
(viii) except through its representatives on the Lockheed Martin Board (or any
committee thereof), otherwise act to seek to control, disrupt or influence the
management, policies or affairs, of Lockheed Martin,
 
                                       95
<PAGE>   101
 
except with the approval of management of Lockheed Martin; (ix) sell or
otherwise transfer in any manner any of Lockheed Martin's voting securities to
any "person" (within the meaning of Section 13(d)(3) of the Exchange Act) who
owns or who as a result of such sale or transfer will own more than 3% of any
class of Lockheed Martin's voting securities or who, without the approval of the
Lockheed Martin Board, has proposed a business combination or similar
transaction with, or a change of control of, Lockheed Martin or who has proposed
a tender offer for Lockheed Martin's voting securities or who has discussed the
possibility of proposing a business combination, tender offer or similar
transaction with, or a change in control of, Lockheed Martin with GE or any of
its respective affiliates or associates, (x) solicit, seek to effect, negotiate
with or provide any information to any other party with respect to, or make any
statement or proposal, whether written or oral, to the Lockheed Martin Board or
any director or officer of Lockheed Martin or otherwise make any public
announcement or proposal whatsoever with respect to, any form of business
combination transaction involving Lockheed Martin, or (xi) instigate or
encourage any third party to do any of the foregoing.
 
BOARD REPRESENTATION
 
     Pursuant to the Standstill Agreement, two members of the Lockheed Martin
Board have been designated by GE. During the term of the Standstill Agreement,
Lockheed Martin's nominating committee will recommend to the Lockheed Martin
Board that such persons or any two other persons designated by GE after
consultation with Lockheed Martin be included in the slate of nominees
recommended to stockholders for election as directors at each annual meeting of
stockholders of Lockheed Martin. Notwithstanding the foregoing, Lockheed
Martin's directors will be elected by its stockholders (subject to the power of
the Lockheed Martin Board to fill vacancies). There is, therefore, no way to
assure that GE's designees will ultimately be elected as directors. If GE
designees are not elected, assuming that Lockheed Martin has satisfied its
obligations under the Standstill Agreement, GE will have no recourse against
Lockheed Martin or any other person or entity.
 
     Notwithstanding the foregoing, GE will not be entitled to designate any
person to the Lockheed Martin Board if such designation would result in any
violation of applicable law, and Lockheed Martin will not be obligated to elect
to the Lockheed Martin Board any person who would cause or be reasonably likely
to cause Lockheed Martin to be unable in any material respect to conduct its
business. However, GE is entitled, in such event, to select alternate designees,
if necessary.
 
     The initial designees of GE to serve on the Lockheed Martin Board are
Messrs. Hood and Murphy. See "MANAGEMENT OF LOCKHEED MARTIN -- Directors."
 
VOTING
 
     During the term of the Standstill Agreement, whenever GE or any of its
affiliates or associates have the right to vote, GE will vote or cause to be
voted, or consent with respect to, all Lockheed Martin voting securities
beneficially owned by it and its affiliates and associates in the manner
recommended by the Lockheed Martin Board, except that at any time when there is
a valid order or judgment of a court of competent jurisdiction or a ruling,
pronouncement or requirement of the NYSE to the contrary, then GE will, if so
requested by the Lockheed Martin Board, vote or cause to be voted all such
voting securities in the same proportion as the votes cast by or on behalf of
the other holders of Lockheed Martin's voting securities. Notwithstanding the
foregoing, GE will be entitled to vote freely, without regard to any request or
recommendation of the Lockheed Martin Board, with respect to certain mergers,
acquisitions and other matters specified in the Lockheed Martin Charter, as to
which the Lockheed Martin Series A Preferred Stock is entitled to vote. See
"DESCRIPTION OF LOCKHEED MARTIN CAPITAL STOCK -- Series A Preferred
Stock -- Voting Rights."
 
     Because GE will be required (with certain exceptions) to vote its shares of
voting stock of Lockheed Martin in accordance with the recommendations of the
Lockheed Martin Board, if GE converts its Lockheed Martin Series A Preferred
Stock and retains the Lockheed Martin Common Stock into which it is converted,
the ability of the Lockheed Martin Board to influence the outcome of any
transaction or other proposal submitted to stockholders will be significantly
enhanced.

<PAGE>   102
 
TRANSFER RESTRICTIONS AND RIGHT OF FIRST OFFER
 
     Subject to the limitation on sales to persons who will own more than 3% of
any class of Lockheed Martin voting securities described in the standstill
provisions above, if GE desires to transfer any Lockheed Martin voting
securities it must give written notice ("GE's Notice") to Lockheed Martin (i)
stating that it desires to make such transfer, and (ii) setting forth the number
of shares of Lockheed Martin voting securities proposed to be transferred (the
"Offered Shares"), the cash price per share that GE proposes to be paid for such
Offered Shares (the "Offer Price"), and the other material terms and conditions
of such transfer. GE's Notice will constitute an irrevocable offer by GE to sell
to Lockheed Martin the Offered Shares at the Offer Price in cash and Lockheed
Martin may elect to purchase all (but not less than all) of the Offered Shares
at the Offer Price in cash. If Lockheed Martin fails to elect to purchase all of
the Offered Shares within 10 business days after receipt of GE's Notice, then GE
may, within a period of 120 days, transfer (or enter into an agreement to
transfer) all or any Offered Shares; provided, that if the purchase price per
share to be paid by any purchaser of the Offered Shares is less than 90% of the
Offer Price (the "Reduced Transfer Price"), GE will promptly provide written
notice to Lockheed Martin of such intended transfer (including the material
terms and conditions thereof) and Lockheed Martin will have the right,
exercisable by delivery of a written election notice to GE within five business
days, to purchase such Offered Shares at the Reduced Transfer Price.
 
RIGHT OF FIRST REFUSAL WITH RESPECT TO RESTRICTED PERSONS
 
     Not less than 30 business days prior to any proposed sale by GE of Lockheed
Martin voting securities to any person who is a significant competitor of
Lockheed Martin or whose ownership of Lockheed Martin voting securities would
cause Lockheed Martin to be materially adversely affected in bidding for or
obtaining contracts with federal, state or local governmental entities (a
"Restricted Person"), GE will give Lockheed Martin notice of the identity of
such Restricted Person and Lockheed Martin will have the right to purchase the
Offered Shares at the Offer Price (or Reduced Transfer Price, as the case may
be) at which the Restricted Person agreed to purchase the Offered Shares. If
Lockheed Martin fails to purchase the Offered Shares within 20 business days, GE
will be permitted to proceed with its sale to such Restricted Person at the
Offer Price or Reduced Transfer Price, as the case may be.
 
RIGHTS PURSUANT TO A TENDER OFFER
 
     GE will have the right to sell or exchange all of its Lockheed Martin
voting securities pursuant to a tender or exchange offer for at least a majority
of Lockheed Martin voting securities (a "Tender Offer"). However, prior to such
sale or exchange, GE will give Lockheed Martin the opportunity to purchase such
voting securities in the manner described below.
 
     GE will give notice (the "Tender Notice") to Lockheed Martin in writing of
its intention to sell or exchange Lockheed Martin voting securities in response
to a Tender Offer no later than three calendar days prior to the latest time
(including any extensions) by which voting securities must be tendered in order
to be accepted pursuant to such Tender Offer, specifying the amount of voting
securities proposed to be tendered by GE (the "Tendered Shares") and the
purchase price per share, specified in the Tender Offer at the time of the
Tender Notice.
 
     Lockheed Martin will have the right to purchase all, but not part, of the
Tendered Shares exercisable by giving written notice (an "Exercise Notice") to
GE at least two calendar days prior to the latest time after delivery of the
Tender Notice by which voting securities must be tendered in order to be
accepted pursuant to the Tender Offer (including any extensions thereof) and
depositing in escrow (or similar arrangement) a sum in cash sufficient to
purchase all Tendered Shares at the price then being offered in the Tender
Offer, without regard to any provision thereof with respect to proration or
conditions to the offerer's obligation to purchase. The purchase price to be
paid by Lockheed Martin for any voting securities so purchased by it will be the
highest price offered or paid in the Tender Offer or in any competing tender
offer, without regard to any provisions thereof with respect to proration or
conditions to the offeror's obligation to purchase.
 
                                       97
<PAGE>   103
 
REGISTRATION RIGHTS
 
     GE will have the right to require Lockheed Martin to register under the Act
all or any portion of the Lockheed Martin Series A Preferred Stock then owned by
GE or any Lockheed Martin Common Stock issued or issuable directly or indirectly
upon conversion of the Lockheed Martin Series A Preferred Stock then owned by GE
(collectively, the "Registrable Securities"), pursuant to not more than five
"demand" registrations, provided that any such registration must include
Lockheed Martin Series A Preferred Stock with an aggregate liquidation
preference of at least $100 million or at least one million shares of Lockheed
Martin Common Stock, subject to adjustment in certain circumstances. In
addition, if Lockheed Martin seeks to register under the Act for sale to the
public any Lockheed Martin voting securities, then Lockheed Martin will, subject
to certain exceptions, include Registrable Securities therein at GE's request (a
"piggyback registration").
 
     GE will pay all agent fees and commissions and underwriting discounts and
commissions related to Registrable Securities being sold by GE and the fees and
disbursements of its counsel and accountants and Lockheed Martin will pay all
fees and disbursements of its counsel and accountants. All other fees and
expenses in connection with any registration statement will (i) in the case of a
demand registration, be borne equally by GE and Lockheed Martin and (ii) in the
case of a piggyback registration, be shared pro rata based upon the respective
market values of the securities to be sold by Lockheed Martin, GE and any other
holders participating in such offering, provided that GE will not pay any
expenses that would otherwise be incurred by Lockheed Martin including, but not
limited to, the preparation and filing of periodic reports with the Commission.
In addition, Lockheed Martin has agreed to enter into customary indemnification
provisions with respect to such registered public offerings.
 
     Any underwriters participating in a distribution of GE's voting securities
of Lockheed Martin pursuant to GE's registration rights will be required to use
all reasonable efforts to effect as wide a distribution as is reasonably
practicable, and in no event will any sale (other than a sale to underwriters
making such a distribution) of shares of voting securities be made knowingly to
any person (including its affiliates or associates and any group in which that
person or its affiliates or associates shall be a member if GE or underwriters
know of the existence of such a group or affiliate or associate) that, after
giving effect to such sale, would beneficially own voting securities
representing 3% or more of the total outstanding securities of Lockheed Martin
entitled to participate in the election of directors. GE must use all reasonable
efforts to secure the agreement of the underwriters, in connection with any such
underwritten offering of Lockheed Martin voting securities, to comply with the
foregoing.
 
     It is possible that GE's registration rights may reduce Lockheed Martin's
flexibility in selecting its ongoing financing alternatives, and in particular
its ability to issue equity securities in the capital markets. However, the
impact of GE's registration rights on Lockheed Martin's overall financial
flexibility and its access to the public capital markets is likely to be
mitigated by several factors. The circumstances surrounding GE's ownership of
Lockheed Martin shares will be publicly disclosed and the market will have had
an opportunity to take account of the potential impact of this ownership.
Lockheed Martin is also entitled to postpone for a reasonable period of time
certain registrations requested by GE if they would interfere with any public
offering of securities, material financings, acquisitions, dispositions,
corporate reorganizations or other material transactions Lockheed Martin is
about to conduct. In addition, Lockheed Martin believes a future market
disruption to be unlikely because Lockheed Martin and GE should have a mutuality
of interest in maximizing stockholder value.
 
SPECIAL LIQUIDITY PROVISIONS
 
     Required GE Offering. No later than 90 days prior to April 2, 2003, GE will
engage a nationally recognized investment banking firm reasonably acceptable to
Lockheed Martin to make an underwritten public offering of all the Lockheed
Martin Series A Preferred Stock then held by GE at a per share price no less
than the liquidation preference per share of the Lockheed Martin Series A
Preferred Stock. Such offering will be conducted so as to satisfy the
requirements for distribution set forth in the next to last paragraph above
under "-- Registration Rights." Lockheed Martin will promptly file a
registration statement registering the
 
                                       98
<PAGE>   104
 
shares of Lockheed Martin Series A Preferred Stock to be sold and GE, Lockheed
Martin and the applicable underwriters will use their best efforts to consummate
such offering, unless the underwriter managing the offering advises Lockheed
Martin in writing that, in such underwriter's good faith opinion, given then-
applicable market conditions, the offering cannot be consummated at the price
and on the terms specified above or that the inclusion of all (or a specified
number) of the shares of Lockheed Martin Series A Preferred Stock in an offering
at the price and on the terms specified above would materially adversely affect
such offering (in which event, GE and Lockheed Martin will proceed with the
unaffected portion of such offering).
 
     Mandatory Conversions; Equity Conversion Securities. If GE continues to own
Lockheed Martin Series A Preferred Stock after the offering contemplated above,
or such offering is not consummated, Lockheed Martin must convert for Equity
Conversion Securities (as described below) on April 2 of each year commencing
April 2, 2003 (a "Mandatory Conversion Date"), $200 million aggregate
liquidation preference of Lockheed Martin Series A Preferred Stock; provided,
however, that to the extent GE has sold, converted or otherwise disposed of any
Lockheed Martin Series A Preferred Stock (including any Lockheed Martin Series A
Preferred Stock redeemed in accordance with its terms) prior to the first
Mandatory Conversion Date, the amount of Lockheed Martin Series A Preferred
Stock to be converted will be reduced by the amount so sold or disposed of in
reverse chronological order (i.e., with the aggregate liquidation preference to
be converted on April 2, 2007 being the first amount so reduced and the
aggregate liquidation preference to be converted on the April 2, 2003 being the
last amount so reduced). Accrued and unpaid dividends to and including the
Mandatory Conversion Date with respect to Lockheed Martin Series A Preferred
Stock subject to mandatory conversion will be paid in cash on the Mandatory
Conversion Date.
 
     "Equity Conversion Securities" means any combination of (i) Lockheed Martin
Common Stock, (ii) a perpetual convertible or non-convertible preferred stock of
Lockheed Martin where the dividend rate is intended to be the rate necessary to
value such preferred stock at its stated liquidation preference (and in any
event no more than 11%) and with such other terms as are customary for issuers
of similar credit posture to Lockheed Martin at the time of issuance (a "Market
Preferred") and (iii) a perpetual 11% non-convertible preferred stock of
Lockheed Martin which is not callable by Lockheed Martin until the fifth
anniversary of the date of issuance and otherwise with terms customary for
issuers of similar credit posture to Lockheed Martin at the time of issuance
("11% Preferred"). GE will have the right to request Backstop Registration (as
described below) for Market Preferred and Lockheed Martin Common Stock issued as
Equity Conversion Securities, but not for 11% Preferred.
 
     No fewer than 30 days prior to a Mandatory Conversion Date, Lockheed Martin
must give written notice to GE of the type or combination of types of Equity
Conversion Securities it intends to issue on such Mandatory Conversion Date, the
number of shares of each such type, the value per share it assigns to each such
type, the aggregate liquidation preference of Lockheed Martin Series A Preferred
Stock it intends to mandatorily convert into each such type and other material
terms of the mandatory conversion.
 
     Backstop Registration. Within 10 days of Lockheed Martin's notice regarding
Equity Conversion Securities, GE may notify Lockheed Martin that, with respect
to all or any part of the Lockheed Martin Series A Preferred Stock being
mandatorily converted and specified in such notice, GE does not wish to retain
the Equity Conversion Securities to be issued in exchange therefor and that it
requests Backstop Registration in respect thereof. GE's notice to Lockheed
Martin will specify those Equity Conversion Securities (if more than one type is
proposed to be issued) as to which it requests Backstop Registration. If GE
fails to elect Backstop Registration within the specified 10-day period, it will
be deemed to have elected to retain all of the Equity Conversion Securities as
proposed in Lockheed Martin's notice.
 
     "Backstop Registration" means an underwritten public offering of the Equity
Conversion Securities relating to those shares of the Lockheed Martin Series A
Preferred Stock held by GE and specified by GE as those which it does not wish
to retain. A Backstop Registration entails the registration for a public
offering of that amount of Equity Conversion Securities, the sale of which in a
public offering must result in proceeds, net of underwriting commissions and
discounts and other offering expenses, not less than the aggregate liquidation
preference of the Lockheed Martin Series A Preferred Stock for which such Equity
Conversion Securities have been mandatorily converted. The managing underwriter
for a Backstop Registration will be selected by
 
                                       99
<PAGE>   105
 
Lockheed Martin and must be reasonably satisfactory to GE. Lockheed Martin will
not be permitted to postpone or decline making the Backstop Registration, in
whole or in part, and GE will bear no expenses with respect thereto. Backstop
Registrations will not be counted toward the five demand registrations of GE for
purposes of GE's registration rights under the Standstill Agreement described
above.
 
     In connection with the pricing of any Backstop Registration, the terms of
the Market Preferred, including its dividend rate, may be changed, in the sole
discretion of Lockheed Martin, from the terms thereof as of the Mandatory
Conversion Date, and will be so changed if required by the managing underwriter
so that the net proceeds of the offering after such change will be sufficient,
in the opinion of such underwriter, to equal or exceed the aggregate liquidation
preference of the Lockheed Martin Series A Preferred Stock mandatorily
converted; provided, however, that no such change may be made if it would have
an adverse effect on GE.
 
     When the Backstop Registration contemplated above has been completed, the
net proceeds thereof will be distributed to GE. Any such offering not
consummated within six months of GE's request therefor will be deemed to have
been abandoned. To the extent the net proceeds of the Backstop Registration are
less than the sum of the aggregate liquidation preference of the Lockheed Martin
Series A Preferred Stock mandatorily converted and the Interest Amount (as
defined below), Lockheed Martin will be obligated to pay to GE an amount in cash
equal to the difference. "Interest Amount" means, with respect to the aggregate
liquidation preference of the Lockheed Martin Series A Preferred Stock
mandatorily converted, interest on such aggregate liquidation preference for
each day, from the applicable Mandatory Conversion Date to and including the
date of payment, at a rate per annum equal to the rate per annum, as published
by the Board of Governors of the Federal Reserve System as reported by the U.S.
Department of Treasury, for such day on U.S. Treasury Bonds maturing on the date
that is the tenth anniversary of such Mandatory Conversion Date (or if no U.S.
Treasury Bonds mature on such date, then on the date nearest to such date for
which such a maturity exists).
 
                              CERTAIN TRANSACTIONS
 
     There are existing business relationships between Lockheed and Martin
Marietta. These relationships are the product of arms-length negotiations
between the corporations. In connection with the preparation of the unaudited
pro forma combined condensed financial statements, adjustments were made to
eliminate intercompany sales and cost of sales between the corporations for the
periods presented. No adjustments were made to eliminate the related
intercompany profit in ending inventories and the net intercompany receivables
and payables as of and for the periods presented as such amounts are not
material. See Note 4(a) under "NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED
FINANCIAL STATEMENTS."
 
              LOCKHEED MARTIN 1995 OMNIBUS PERFORMANCE AWARD PLAN
 
     For a number of years, Lockheed and Martin Marietta have utilized
share-based and cash-based plans designed to assist each corporation in
attracting, motivating, retaining and rewarding talented and experienced
individuals. The Lockheed Board and the Martin Marietta Board each believe that
these plans have encouraged and rewarded participating officers and employees
who have contributed to the success of each corporation. The stockholders of
Lockheed and Martin Marietta are being asked at their respective special
meetings to consider and approve the adoption of a new plan for Lockheed Martin
which provides for certain share-based and cash-based awards to employees of
Lockheed Martin and its subsidiaries.
 
GENERAL
 
     The Lockheed Martin Board has adopted and the Lockheed Board and the Martin
Marietta Board have approved the Lockheed Martin Omnibus Plan, subject to the
approval by the respective stockholders of Lockheed and Martin Marietta. If so
approved, the Lockheed Martin Omnibus Plan will then become effective, and no
further awards will be granted under the current stock incentive plans of
Lockheed or Martin Marietta. All outstanding grants and awards under those
plans, however, will remain in effect and be converted into grants or awards in
or based on Lockheed Martin Common Stock. See "THE REORGANIZATION
 
                                       100
<PAGE>   106
 
AGREEMENT -- Certain Benefits Matters." A copy of the full text of the Lockheed
Martin Omnibus Plan is set forth in Appendix IV to this Joint Proxy
Statement/Prospectus and the following description is qualified in its entirety
by reference to Appendix IV.
 
     Awards under the Lockheed Martin Omnibus Plan may be granted to officers
and other key salaried employees of Lockheed Martin and its subsidiaries. No
individual, however, who beneficially owns stock possessing 5% or more of the
combined voting power of all classes of stock of Lockheed Martin will be
eligible to participate. Lockheed and Martin Marietta estimate that all officers
of Lockheed Martin, including all officers listed under "MANAGEMENT OF LOCKHEED
MARTIN -- Officers" (four of whom are also directors of Lockheed Martin), will
be among those eligible to receive awards, subject to the discretion of the
Committee (as defined below) to determine the particular individuals who, from
time to time, will be selected to receive awards. The number of key salaried
employees of Lockheed Martin and its subsidiaries eligible to receive awards has
not been determined at this time. In addition, neither the individuals who are
to receive awards, the number of awards that will be granted to any individual
or group of individuals, nor the amounts to be payable with respect to awards,
have been determined at this time. The Lockheed Martin Omnibus Plan will remain
in existence as to all outstanding awards until all such awards are either
exercised or terminated; however, no award can be made after September 21, 2004.
 
TYPES OF AWARDS
 
     Awards under the Lockheed Martin Omnibus Plan may be in the form of
nonqualified stock options, incentive stock options, stock appreciation rights
(SARs), restricted stock and other share-based incentive awards, or cash-based
incentive awards, such as performance units. Awards may be granted singly or in
combination with other awards, consistent with the terms of the Lockheed Martin
Omnibus Plan. Each award will be evidenced by an award agreement entered into
between Lockheed Martin and the recipient setting forth the specific terms and
conditions applicable to that award. Awards under the Lockheed Martin Omnibus
Plan that are not vested or exercised generally will be nontransferable by a
holder (other than by will or the laws of descent and distribution) and rights
thereunder generally will be exercisable, during the holder's lifetime, only by
the holder, subject to such exceptions as (consistent with applicable legal
considerations) may be authorized from time to time by the Committee. The
maximum term of unvested or unexercised awards under the Lockheed Martin Omnibus
Plan is ten years after the initial date of grant.
 
     Stock options authorized under the Lockheed Martin Omnibus Plan are rights
to purchase a specified number of shares of Lockheed Martin Common Stock at an
exercise price of not less than 100% of the fair market value of the stock on
the date of grant (or date of amendment of the exercise price, if any) during
the period set forth in the award agreement. Stock options that are granted as
incentive stock options will be granted with such additional terms as are
necessary to satisfy the applicable requirements of Section 422 of the Code. The
fair market value of the Lockheed Martin Common Stock for which incentive stock
options are exercisable for the first time by an optionee during any calendar
year can not exceed $100,000 (measured as of the date of grant) under current
tax law. Other awards are not limited in this manner.
 
     SARs entitle the recipient to receive, upon exercise of the SAR, an amount
(payable in cash and/or stock or other property) equal to the amount of the
excess, if any, of the fair market value of a share of Lockheed Martin Common
Stock on the date the SAR is exercised (or some lesser ceiling amount) over the
base price of the SAR, which cannot be less than the fair market value of a
share of the Lockheed Martin Common Stock on the date the SAR was awarded or the
exercise price of a related stock option. SARs may be granted on a free-standing
basis, in relation to a stock option or in "tandem" with a stock option, such
that the exercise of either the option or the SAR cancels the recipient's rights
under the tandem award with respect to the number of shares so exercised.
 
     Restricted stock is Lockheed Martin Common Stock issued to the recipient,
typically for minimal lawful consideration and subject to certain risks of
forfeiture and restrictions and limitations on transfer, the vesting of which
may depend on individual or corporate performance, continued service or other
criteria.
 
     Other share-based incentive awards might include phantom stock or units,
performance stock or units, bonus stock or units, dividend equivalent units,
similar securities or rights and other awards payable in or with
 
                                       101
<PAGE>   107
 
a value derived from or a price related to the fair market value of the Lockheed
Martin Common Stock, payable in Lockheed Martin Common Stock and/or cash, all on
such terms as the Committee may approve. Such awards may be granted, become
vested or be payable based upon the continued employment of a participant, or
upon the attainment of specified corporate or individual performance goals (as
in the case of performance stock or units).
 
     The Lockheed Martin Omnibus Plan also provides for the grant of long-term
incentive awards that are not denominated nor payable in and do not have a value
derived from the value of or a price related to shares of Lockheed Martin Common
Stock and are payable only in cash ("Cash-Based Awards"). Under recent changes
in the federal tax laws ("Section 162(m)"), Lockheed Martin may not deduct
certain compensation of over $1,000,000 in any year to the Chief Executive
Officer or one of the four other most highly compensated executive officers of
Lockheed Martin ("Executive Officers") unless, among other things, this
compensation qualifies as "performance-based compensation" under Section 162(m),
and the material terms of the plan for such compensation are stockholder
approved. Cash-Based Awards to Executive Officers are intended to satisfy the
requirements for performance-based compensation under Section 162(m). With
reference to the Cash-Based Awards, the material terms of the Lockheed Martin
Omnibus Plan include the eligible class of participants, the performance goal or
goals and the maximum annual amount payable thereunder to any individual
participant.
 
     The eligible class of persons for Cash-Based Awards under the Lockheed
Martin Omnibus Plan is all key salaried employees of Lockheed Martin and its
subsidiaries. Cash-Based Awards granted to Executive Officers thereunder may be
granted only in accordance with the requirements of Section 162(m), as set forth
below. Cash-Based Awards to other key salaried employees may or may not be
limited by the requirements of Section 162(m), but will in any event be based on
the performance goals described below.
 
     The performance goals for Cash-Based Awards under the Lockheed Martin
Omnibus Plan are any one or a combination of Earnings Per Share, Return on
Equity, Total Stockholder Return and Cash Flow (each as defined in the Lockheed
Martin Omnibus Plan). These goals will be applied over either consecutive or
rolling cycles of more than one but not more than five fiscal years. Specific
cycles, weightings of more than one performance goal and target levels of
performance upon which actual payments will be based, as well as the award
levels payable upon achievement of specified levels of performance, will be
determined by the Committee (as defined below) not later than the applicable
deadline under Section 162(m) and in any event at a time when achievement of
such targets is substantially uncertain. These variables may change from cycle
to cycle. Appropriate adjustments to the performance goals and targets in
respect of Cash-Based Awards may be made by the Committee based upon objective
criteria in the case of significant acquisitions or dispositions by Lockheed
Martin, extraordinary gains or losses, material changes in accounting principles
or practices, or certain other events that in any case were not anticipated (or
the effects of which were not anticipated) at the time goals were established,
in order to neutralize the effect of such events on the Cash-Based Awards.
Lockheed and Martin Marietta believe that specific performance targets (when
established) are likely to constitute confidential business information, the
disclosure of which may adversely affect Lockheed Martin or mislead the public.
 
     The Committee must certify the achievement of the applicable performance
goals and the actual amount payable to each participant under the Cash-Based
Awards prior to payment. Cash-Based Awards generally will be paid following the
completion of each cycle. The Committee may retain discretion to reduce, but not
increase, the amount payable under a Cash-Based Award to any participant,
notwithstanding the achievement of targeted performance goals. Cash-Based Awards
may be accelerated in the event of a Change in Control of Lockheed Martin, as
described below. The maximum amount payable to any participant under all
Cash-Based Awards during any calendar year will be $3,000,000. There is no
maximum aggregate dollar amount of Cash-Based Awards under the Lockheed Martin
Omnibus Plan.
 
     In addition to Cash-Based Awards, other types of awards under the Lockheed
Martin Omnibus Plan may be granted to qualify as performance-based compensation
under Section 162(m). Stock options and SARs that are granted under the Lockheed
Martin Omnibus Plan at a fair market value exercise price are intended to
qualify as performance-based compensation. In addition, other share-based awards
(such as restricted stock
 
                                       102
<PAGE>   108
 
or performance units) may be granted under the plan to qualify as
performance-based compensation under Section 162(m). With reference to such
other share-based awards intended to so qualify, the material terms of the
Lockheed Martin Omnibus Plan are similar to those described above for Cash-Based
Awards: the eligible class of persons is all key salaried employees of Lockheed
Martin and its subsidiaries, and the performance goals are any one or a
combination of Earnings Per Share, Return on Equity, Total Stockholder Return
and Cash Flow. The certification and payout procedures and nature of Committee
discretion with respect to the other share-based awards are substantially the
same as for the Section 162(m) Cash-Based Awards. The maximum number of shares
(or share units) of Lockheed Martin Common Stock that may be subject to all
qualifying share-based awards, including stock options and SARs, that are
granted to any participant during any calendar year will not exceed 500,000
shares (or share units), either individually or in the aggregate.
 
     The Committee also has the authority to grant awards under the Lockheed
Martin Omnibus Plan in substitution for or assumption of stock incentive awards
held by employees of other entities who become employees of Lockheed Martin or a
subsidiary as a result of a merger or acquisition of the entity.
 
     Awards may be granted in connection with the surrender or cancellation of
previously granted awards, or may be amended, under such terms and conditions,
including numbers of shares and exercise price, exercisability or termination,
that are the same as or different from the existing awards, all as the Committee
may approve. Any amendment of an award to reduce its exercise or purchase price
will be subject to stockholder approval, except in the event of a change in
control or upon certain reorganization or recapitalization events or certain
anti-dilutive adjustments, as described below under "Authorized Shares; Other
Provisions; Non-Exclusivity".
 
ADMINISTRATION; CHANGE IN CONTROL
 
     The Lockheed Martin Omnibus Plan provides that it will be administered by a
committee of the Lockheed Martin Board ("Committee"), constituted so as to
permit the plan to comply with the "disinterested administration" requirements
of Rule 16b-3 under the Exchange Act and the "outside director" requirements of
Section 162(m). The Committee will have the authority within the terms and
limitations of the Lockheed Martin Omnibus Plan to designate recipients of
awards, determine or modify the form, amount, terms, conditions, restrictions,
and limitations of awards, including vesting provisions, terms of exercise of an
award, expiration dates and the treatment of an award in the event of the
retirement, disability, death or other termination of a participant's employment
with Lockheed Martin, and to construe and interpret the Lockheed Martin Omnibus
Plan. Such authority includes the discretion to accelerate, extend and reduce
(subject to the limitations noted above) the exercise price of outstanding
awards.
 
     The Committee is authorized to include specific provisions in award
agreements relating to the treatment of awards in the event of a "Change in
Control" of Lockheed Martin (as defined in the Lockheed Martin Omnibus Plan) and
is authorized to take certain other actions in such an event. Change in Control
under the Lockheed Martin Omnibus Plan is defined generally to include a change
in ownership involving 25% or more of the outstanding voting securities of
Lockheed Martin (or a combined entity), a transfer of substantially all of its
assets, or a change in a majority of the members of its Board of Directors as a
result of any such change or reorganization or a contested election.
 
     The Committee may delegate to the officers or employees of Lockheed Martin
or its subsidiaries the authority to execute and deliver such instruments and
documents and to take actions necessary, advisable or convenient for the
effective administration of the Lockheed Martin Omnibus Plan. It is intended
generally that the share-based awards under the Lockheed Martin Omnibus Plan and
the Lockheed Martin Omnibus Plan itself comply with and (as to share-based
awards) be interpreted in a manner that, in the case of participants who are
subject to Section 16 of the Exchange Act and for whom (or whose awards) the
benefits of Rule 16b-3 are intended, satisfy the applicable requirements of Rule
16b-3, so that such persons will be entitled to the benefits of Rule 16b-3 or
other exemptive rules under that Section. In general, the Cash-Based Awards will
not be subject to Section 16. The Lockheed Martin Omnibus Plan provides that
neither Lockheed
 
                                       103
<PAGE>   109
 
Martin nor any member of the Lockheed Martin Board or of the Committee shall
have any liability to any person for any action taken or not taken in good faith
under the Lockheed Martin Omnibus Plan.
 
AMENDMENT AND TERMINATION
 
     The Lockheed Martin Board will have the authority to amend, suspend or
discontinue the Lockheed Martin Omnibus Plan at any time, provided that no such
action will affect any outstanding award in any manner adverse to the
participant without the consent of the participant. The Lockheed Martin Omnibus
Plan may be amended by the Lockheed Martin Board without further stockholder
approval, and no guidelines have been established relating to the nature of the
amendments that may be made to the Plan without stockholder approval. Such
approval, however, may be required (e.g., in the case of amendments that
materially increase the available number of shares under the Lockheed Martin
Omnibus Plan) to preserve the qualifying status of the Lockheed Martin Omnibus
Plan under Rule 16b-3, to satisfy tax rules applicable to performance-based
compensation under Section 162(m) or to subsequent grants of incentive stock
options, or to satisfy other applicable legal requirements. Amendments made
without stockholder approval could increase the costs to Lockheed Martin under
the Lockheed Martin Omnibus Plan, although the amount thereof is not
determinable. Because the Committee will retain the discretion to set and change
the specific targets for each performance period under a performance-based award
intended to be exempt from Section 162(m), stockholder ratification of the
performance goals will be required, in any event at five-year intervals in the
future to exempt awards granted under the Lockheed Martin Omnibus Plan from the
limitations on deductibility.
 
AUTHORIZED SHARES; OTHER PROVISIONS; NON-EXCLUSIVITY
 
     The number of shares of Lockheed Martin Common Stock that may be issued in
respect of awards under the Lockheed Martin Omnibus Plan will not exceed
12,000,000 shares. An equal number of share units representing share-based
awards exercisable for or payable in cash will also be available. Shares of
Lockheed Martin Common Stock subject to share-based awards payable in cash or
stock (whether at the discretion of Lockheed Martin or the participant) will
initially be counted against each of the share limit and the share unit limit.
When payment is ultimately made in respect to the award in either shares or
cash, a number of shares or share units relating to the alternative form of
consideration not so paid will be recredited to the applicable limit. The
12,000,000 figure for each of the number of shares and the number of units to be
available under the Plan is based on an estimate of the number of shares and
units that will be subject to awards granted during the first five years of the
term of the Plan.
 
     The number and kind of shares available for grant and the shares subject to
outstanding awards (as well as individual share and share unit limits on awards,
performance targets and exercise prices of awards) may be adjusted to reflect
the effect of a stock dividend, split, recapitalization, merger, consolidation,
reorganization, combination or exchange of shares, extraordinary dividend or
other distribution or other similar transaction. Any unexercised or
undistributed portion of any expired, cancelled, terminated or forfeited award,
or any alternative form of consideration under an award that is not paid in
connection with the settlement of any portion of an award, will again be
available for award under the Lockheed Martin Omnibus Plan, whether or not the
participant has received benefits of ownership (such as dividends or dividend
equivalents or voting rights) during the period in which the participant's
ownership was restricted or otherwise not vested. Although shares subject to
repriced or cancelled options or SARs will be counted against the individual
share-based award limits to the extent required by Section 162(m), only shares
actually issued or share units actually paid will be charged against the
aggregate share or share unit limits, respectively, under the Lockheed Martin
Omnibus Plan. Upon approval of the Lockheed Martin Omnibus Plan by the
stockholders and consummation of the Combination, Lockheed Martin intends to
register under the Act the number of shares of Lockheed Martin Common Stock
reserved for issuance under the Lockheed Martin Omnibus Plan.
 
     Full payment for shares purchased on exercise of any option, along with
payment of any required tax withholding, must be made at the time of such
exercise in cash or, if permitted by the Committee, in exchange for a promissory
note in favor of Lockheed Martin, in shares of stock having a fair market value
equivalent to the exercise price and withholding obligation, or any combination
thereof, or pursuant to such "cashless
 
                                       104
<PAGE>   110
 
exercise" procedures as may be permitted by the Committee. Any payment required
in respect of other awards may be in such amount and in any lawful form of
consideration as may be authorized by the Committee.
 
     The Lockheed Martin Omnibus Plan does not impose any minimum vesting
periods on options or other awards. However, shares of stock acquired after
exercise of an option may not, in the ordinary course, be sold before the
expiration of six months from the date of grant. The maximum term of an option
or any other award is ten years.
 
     The Lockheed Martin Omnibus Plan is not exclusive and does not limit the
authority of the Lockheed Martin Board or its committees to grant awards or
authorize any other compensation, with or without reference to the Lockheed
Martin Common Stock, under any other plan or authority. The Lockheed Martin
Omnibus Plan is not expected to be the exclusive cash incentive plan for
eligible persons (including Executive Officers) of Lockheed Martin and its
subsidiaries; other cash incentive plans (such as short-term or operating entity
specific plans) may be retained and/or developed to implement Lockheed Martin's
broader-based compensation objectives and policies. Approval of the adoption of
the Lockheed Martin Omnibus Plan by the stockholders of Lockheed and Martin
Marietta will not be deemed to constitute an approval of any such other
compensation, plan or authority.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a general description of Federal income tax consequences
to participants and Lockheed Martin relating to nonqualified and incentive stock
options and certain other awards that may be granted under the Lockheed Martin
Omnibus Plan. This discussion does not purport to cover all tax consequences
relating to stock options and other awards.
 
     An optionee will not recognize income upon the grant of a nonqualified
stock option to purchase shares of Lockheed Martin Common Stock. Upon exercise
of the option, the optionee will recognize ordinary compensation income equal to
the excess of the fair market value of the Lockheed Martin Common Stock on the
date the option is exercised over the option price for such stock. The tax basis
of the option stock in the hands of the optionee will equal the option price for
the stock plus the amount of ordinary compensation income the optionee
recognizes upon exercise of the option, and the holding period for the stock
will commence on the day the option is exercised. An optionee who sells option
stock will recognize capital gain or loss measured by the difference between the
tax basis of the stock and the amount realized on the sale. Such gain or loss
will be long-term if the stock is held for more than one year after exercise.
Lockheed Martin or a subsidiary will be entitled to a deduction equal to the
amount of ordinary compensation income recognized by the optionee. The deduction
will be allowed at the same time the optionee recognizes the income.
 
     An optionee will not recognize income upon the grant of an incentive stock
option to purchase shares of Lockheed Martin Common Stock, and will not
recognize income upon exercise of the option, provided such optionee was an
employee of Lockheed Martin or a subsidiary at all times from the date of grant
until three months prior to exercise (or one year prior to exercise in the event
of death or disability). Generally, the amount by which the fair market value of
the Lockheed Martin Common Stock on the date of exercise exceeds the option
price will be includable in alternative minimum taxable income for purposes of
determining alternative minimum tax and such amount will be added to the tax
basis of such stock for purposes of determining alternative minimum taxable
income in the year the stock is sold. Where an optionee who has exercised an
incentive stock option sells the shares acquired upon exercise more than two
years after the grant date and more than one year after exercise, long-term
capital gain or loss will be recognized equal to the difference between the
sales price and the option price. An optionee who sells such shares within two
years after the grant date or within one year after exercise will recognize
ordinary compensation income in an amount equal to the lesser of the difference
between (a) the option price and the fair market value of such shares on the
date of exercise or (b) the option price and the sales proceeds. Any remaining
gain or loss will be treated as a capital gain or loss. Lockheed Martin or a
subsidiary will be entitled to a deduction equal to the amount of ordinary
compensation income recognized by the optionee in this case. The deduction will
be allowable at the same time the optionee recognizes the income.
 
                                       105
<PAGE>   111
 
     The current federal income tax consequences of other awards authorized
under the plan generally follow certain basic patterns: SARs are taxed and
deductible in substantially the same manner as nonqualified stock options;
nontransferable restricted stock subject to a substantial risk of forfeiture
results in income recognition equal to the excess of the fair market value of
the stock over the purchase price (if any) only at the time the restrictions
lapse (unless the recipient elects to accelerate recognition as of the date of
grant); performance awards and dividend equivalents generally are subject to tax
at the time of payment; unconditional stock bonuses are generally subject to tax
measured by the value of the payment received; and Cash-Based Awards generally
are subject to tax at the time of payment; in each of the foregoing cases,
Lockheed Martin will generally have (at the time the participant recognizes
income) a corresponding deduction.
 
     If, as a result of a change in control event, a participant's options or
SARs or other rights become immediately exercisable, or restrictions immediately
lapse on an award, or cash, shares or other benefits covered by another type of
award are immediately vested or issued, the additional economic value, if any,
attributable to the acceleration or issuance may be deemed a "parachute payment"
under Section 280G of the Code. In such case, the participant may be subject to
a 20% non-deductible excise tax as to all or a portion of such economic value,
in addition to any income tax payable. Lockheed Martin will not be entitled to a
deduction for that portion of any parachute payment that is subject to the
excise tax.
 
     Notwithstanding any of the foregoing discussion with respect to the
deductibility of compensation under the Lockheed Martin Omnibus Plan, Section
162(m) would render non-deductible to Lockheed Martin certain compensation in
excess of $1,000,000 in any year to certain executive officers of Lockheed
Martin, unless such excess compensation is "performance-based" (as defined) or
is otherwise exempt from Section 162(m). The applicable conditions of an
exemption for a performance-based compensation plan include, among others, a
requirement that the stockholders approve the material terms of the plan. Stock
options, SARs and certain (but not all) other types of awards that may be
granted to Executive Officers as contemplated by the Lockheed Martin Omnibus
Plan are intended to qualify for the exemption for performance-based
compensation under Section 162(m). However, in light of the ambiguities in
Section 162(m) and uncertainties regarding its ultimate interpretation and
application in these circumstances, no assurances can be given that compensation
paid under the Lockheed Martin Omnibus Plan to any Executive Officer will in
fact be deductible if it should, together with other non-exempt compensation
paid to such Executive Officer, exceed $1,000,000.
 
THE RESPECTIVE BOARDS OF DIRECTORS OF LOCKHEED AND MARTIN MARIETTA EACH
RECOMMEND A VOTE FOR ADOPTION OF THE LOCKHEED MARTIN 1995 OMNIBUS PERFORMANCE
AWARD PLAN.
 
                 LOCKHEED MARTIN DIRECTORS DEFERRED STOCK PLAN
 
     Lockheed and Martin Marietta expect that Lockheed Martin's initial
arrangement with respect to remuneration of non-employee Directors will include
an annual retainer of $35,000, in addition to other compensation described
herein. See "MANAGEMENT OF LOCKHEED MARTIN -- Compensation of Directors." The
stockholders of Lockheed Martin are being asked at their respective meetings to
consider and approve the annual accrual of $10,000 of this amount in the form of
share credits payable solely in Lockheed Martin Common Stock by the adoption of
the new Lockheed Martin Directors Plan.
 
     The Lockheed Martin Board has adopted and the Lockheed Board and the Martin
Marietta Board have approved the Lockheed Martin Directors Plan, subject to the
approval by the respective stockholders of Lockheed and Martin Marietta. The
purpose of the Lockheed Martin Directors Plan is to attract and retain persons
of exceptional ability to serve as directors and further align the common
interests of directors and stockholders in enhancing the value of Lockheed
Martin Common Stock. No additional dollars will be paid to directors through
this Plan. Participation is not voluntary. Shares of Lockheed Martin Common
Stock credited under the Lockheed Martin Directors Plan will be in lieu of an
equivalent cash portion of the retainer otherwise payable to directors.
 
                                       106
<PAGE>   112
 
     The following description of the principal features of the Lockheed Martin
Directors Plan is qualified in its entirety by reference to the complete text of
the Lockheed Martin Directors Plan, a copy of which is set forth in Appendix V
to this Joint Proxy Statement/Prospectus.
 
     Under the Lockheed Martin Directors Plan, each eligible director will
receive, on June 1 of each year, share credits equal to the number of shares of
Lockheed Martin Common Stock that $10,000 would then buy. All share credits will
be fully vested as accrued. Eligible directors include all directors who are
compensated in such capacity through retainers and who are not officers or
employees of Lockheed Martin or a subsidiary. Twenty of the proposed directors
of Lockheed Martin will be eligible to participate in this Plan. The value of
the Lockheed Martin Common Stock for purpose of establishing the number of share
credits will be its fair market value at the time of crediting, based on the
average reported price over the preceding ten trading days. Over the 10-year
term of the Lockheed Martin Directors Plan, an aggregate of 50,000 shares of
Lockheed Martin Common Stock may be issued to all eligible directors in the
aggregate, in lieu of a portion of their cash retainers. Upon approval of the
Lockheed Martin Directors Plan by the stockholders and consummation of the
Combination, Lockheed Martin intends to register under the Act the number of
shares of Lockheed Martin Common Stock reserved for issuance under the Lockheed
Martin Directors Plan.
 
     Share credits accrued will constitute bookkeeping entries that will be
settled and paid in an equivalent number of shares of Lockheed Martin Common
Stock upon the director's termination of service on the Lockheed Martin Board. A
director may irrevocably elect to receive his or her accrued share credits in a
lump-sum or in equal annual installments over a period of up to five years after
termination of service. However, in the case of a director's termination of
service as a result of death or disability, the share credits will be paid in a
lump-sum after a director's service as a director ends. During the period the
director's interest is represented by share credits, a director will have no
voting, dividend or other rights of a stockholder with respect to the shares to
be issued in his or her name, but will be entitled to additional share credits
representing dividend equivalents based on cash distributions on the underlying
shares (converted to share credits based on the market value of shares on the
applicable dividend payment dates). The number of share credits and shares
subject to the Lockheed Martin Directors Plan are subject to appropriate
adjustment in event of stock split, recapitalization or other reorganization.
 
     If the Lockheed Martin Directors Plan had been in effect in 1994 and the
Combination had occurred as currently contemplated but as of January 1, 1994,
the annual benefit to each eligible director and to all 20 eligible directors as
a group, based on the average closing prices of Lockheed and Martin Marietta
Common Stock (converted on a pro forma basis based on shares then outstanding)
as of June 1, 1994, would have been 243 share credits (calculated based on the
$10,000 annual share credit divided by a pro forma share price of $41.15 per
share) and 4,860 share credits in the aggregate, respectively, prior to
crediting for any dividend equivalents thereon from June 1 to December 31, 1994.
 
     The compensation of directors, including the Lockheed Martin Directors
Plan, may be amended from time to time by the Lockheed Martin Board in its sole
discretion, without stockholder approval, but subject to applicable legal
requirements. No guidelines have been established relating to the nature of the
amendments that may be made to the Lockheed Martin Directors Plan without
stockholder approval, but such approval may be required to preserve the
qualifying status of the Plan under Rule 16b-3 under the Exchange Act.
Amendments made without stockholder approval could increase the costs of the
Lockheed Martin Directors Plan, although the amount thereof is not determinable.
Consent of the director will be required to revoke or alter an outstanding award
in a manner unfavorable to such director. The term of the Lockheed Martin
Directors Plan is 10 years, subject to earlier termination by the Lockheed
Martin Board.
 
     In general, under current federal income tax laws, share credits under the
Lockheed Martin Directors Plan will be includible in taxable income of an
eligible director and deductible to Lockheed Martin based on the fair market
value of the Lockheed Martin Common Stock at the time or times the share credits
are paid in shares to a director following termination of service.

     If the Combination is consummated, the first annual meeting of the public
stockholders of Lockheed Martin after such consummation is expected to be held

of stockholders of Lockheed is expected to be held on or about May 9, 1995 and
the 1995 annual meeting of stockholders of Martin Marietta is expected to be
held on or about June 23, 1995.
 
     Subject to the foregoing, if any Lockheed Martin stockholder intends to
present a proposal at the 1996 Lockheed Martin annual meeting and wishes to have
such proposal considered for inclusion in the proxy materials for such meeting,
such holder must submit the proposal to the Secretary of Lockheed Martin in
writing so as to be received at the executive offices of Lockheed Martin by

proposals. In the event the Combination is not consummated, the only stockholder
proposals eligible to be considered for inclusion in the proxy materials for the
1995 annual meetings of Lockheed and Martin Marietta will be those which were
duly submitted to the Secretary of Lockheed by December 8, 1994 or the Corporate
Secretary of Martin Marietta by November 18, 1994, as the case may be, as
provided in the respective 1994 Annual Meeting Proxy Statements of Lockheed and

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Stockholders of
Lockheed Martin Corporation:
 
     We have audited the accompanying consolidated balance sheet of Lockheed
Martin Corporation as of October 31, 1994. This consolidated balance sheet is
the responsibility of Lockheed Martin Corporation's management. Our
responsibility is to express an opinion on this consolidated balance sheet based
on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated balance sheet is free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the consolidated balance sheet. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall consolidated
balance sheet presentation. We believe that our audit provides a reasonable
basis for our opinion.
 
     In our opinion, the consolidated balance sheet referred to above presents
fairly, in all material respects, the financial position of Lockheed Martin
Corporation at October 31, 1994 in conformity with generally accepted accounting
principles.

the laws of the State of Maryland and Lockheed is a corporation duly organized
and existing under the laws of the State of Delaware; and
 
     WHEREAS, Parent is a corporation duly organized under the laws of the State
of Maryland, with Martin Marietta and Lockheed each owning one-half of the

     NOW, THEREFORE, in consideration of the mutual agreements, provisions and
covenants contained in this Agreement, the parties hereby agree as follows:
 
                                   ARTICLE I
                                  THE MERGERS
 
     SECTION 1.1  Charter and Bylaws of Parent.  The Charter and Bylaws of
Parent shall be amended prior to the Merger Date (as hereinafter defined) to be
in substantially the form of Exhibits A and B hereto, respectively, and the name
of Parent shall be changed to Lockheed Martin Corporation. From the date hereof
until the Merger Date, Martin Marietta and Lockheed shall consult with each
other prior to causing or permitting Parent to take any action and neither shall
cause or permit Parent to take any action inconsistent with the provisions of
this Agreement without the written consent of the other.
 
     SECTION 1.2  Atlantic Sub Merger.  (a) Martin Marietta and Lockheed will
cause Parent to form a wholly owned subsidiary named Atlantic Sub, Inc.
("Atlantic Sub") under the laws of the State of Maryland. Atlantic Sub will be
formed solely to facilitate the Atlantic Sub Merger referred to below and will
conduct no business or activity other than in connection with the Atlantic Sub
Merger. Martin Marietta and Lockheed will cause Parent to cause Atlantic Sub to
execute and deliver, and Martin Marietta agrees to execute and deliver and to
submit to its stockholders for approval, together with this Agreement in
accordance with Article II, an Agreement and Plan of Merger (the "Atlantic Sub
Merger Agreement") in substantially the form attached hereto as Exhibit C,
providing for the merger of Atlantic Sub with and into Martin Marietta (the

the Atlantic Sub Merger and as a result thereof shall become a wholly owned
subsidiary of Parent.

          (i) each share of Martin Marietta Common Stock (as hereinafter
     defined) outstanding immediately prior to the effective time of the
     Atlantic Sub Merger, other than any shares of Martin Marietta Common Stock
     owned by Lockheed or any Subsidiary (as hereinafter defined) of Lockheed,
     shall be converted into and become one share of common stock, par value
     $1.00 per share, of Parent ("Parent Common Stock");
 
          (ii) each share of Martin Marietta Preferred Stock (as hereinafter
     defined) outstanding immediately prior to the effective time of the
     Atlantic Sub Merger, other than any shares of Martin Marietta Preferred
     Stock owned by Lockheed or any Subsidiary of Lockheed, shall be converted

                                       I-1
<PAGE>   124
 
     one share of Series A Preferred Stock, par value $1.00 per share, of Parent
     ("Parent Preferred Stock"); and
 
          (iii) each share of Martin Marietta Common Stock and Martin Marietta
     Preferred Stock owned by Lockheed or any Subsidiary of Lockheed shall be
     cancelled and cease to exist immediately upon the effective time of the
     Atlantic Sub Merger without any payment being made in respect thereof.
 
     (c) The parties will take such action as may be necessary to cause Parent
to reserve sufficient shares of Parent Common Stock following the Mergers (as
hereinafter defined) to permit conversion of the Parent Preferred Stock and
delivery of shares of Parent Common Stock upon conversion thereof following the
Atlantic Sub Merger. Subject to the terms and conditions of this Agreement,
Martin Marietta shall use its reasonable efforts to cause the Atlantic Sub
Merger to be consummated in accordance with the terms of the Atlantic Sub Merger
Agreement. Martin Marietta and Lockheed will cause Parent to execute a formal
written consent under Section 2-505 of the Maryland General Corporation Law (the
"Maryland Statute"), as the sole stockholder of Atlantic Sub, to the execution,
delivery and performance of the Atlantic Sub Merger Agreement by Atlantic Sub.
 
     SECTION 1.3  Pacific Sub Merger.  (a) Lockheed and Martin Marietta will
cause Parent to form a wholly owned subsidiary named Pacific Sub, Inc. ("Pacific
Sub") under the laws of the State of Delaware. Pacific Sub will be formed solely
to facilitate the Pacific Sub Merger referred to below and will conduct no
business or activity other than in connection with the Pacific Sub Merger.
Lockheed and Martin Marietta will cause Parent to cause Pacific Sub to execute
and deliver, and, subject to the terms and conditions of this Agreement,
Lockheed agrees to execute and deliver and to submit to its stockholders for
adoption and approval, together with this Agreement in accordance with Article
II, an Agreement and Plan of Merger (the "Pacific Sub Merger Agreement") in
substantially the form attached hereto as Exhibit D, providing for the merger of
Pacific Sub with and into Lockheed (the "Pacific Sub Merger"). Lockheed shall be
the surviving corporation in the Pacific Sub Merger and as a result thereof
shall become a wholly owned subsidiary of Parent.
 
     (b) Pursuant to the Pacific Sub Merger:
 
          (i) each share of Lockheed Common Stock (as hereinafter defined)
     outstanding immediately prior to the effective time of the Pacific Sub
     Merger, other than any shares of Lockheed Common Stock owned by Martin
     Marietta or any Subsidiary of Martin Marietta or held in the treasury of
     Lockheed, shall be converted into and become the right to receive 1.63
     shares of Parent Common Stock; and
 
          (ii) each share of Lockheed Common Stock owned by Martin Marietta or
     any Subsidiary of Martin Marietta or held in the treasury of Lockheed shall
     be cancelled and cease to exist immediately upon the effective time of the
     Pacific Sub Merger without any payment being made in respect thereof.
 
Notwithstanding the foregoing, no fractional shares of Parent Common Stock will
be issued as a result of the Pacific Sub Merger. In lieu of the issuance of
fractional shares, cash payments will be made to holders of Lockheed Common
Stock in respect of any fractional share that would otherwise be issuable in an
amount equal to such fractional part of a share of Parent Common Stock
multiplied by the closing price of a share of Parent Common Stock on the New
York Stock Exchange (the "NYSE") on the last business day preceding the Merger
Date if such stock is then being traded, including without limitation trading on
a "when issued" basis, and otherwise shall be the closing price on the first
business day that such stock is traded. No such holder shall be entitled to
dividends, voting rights, or any other stockholder right in respect of any
fractional share. For this purpose, shares held of record by any particular
stockholder of Lockheed and represented by two or more certificates may be
aggregated.
 
     (c) Subject to the terms and conditions of this Agreement, Lockheed shall
use its reasonable efforts to cause the Pacific Sub Merger to be consummated in
accordance with the terms of the Pacific Sub Merger Agreement. Lockheed and
Martin Marietta will cause Parent to execute a formal written consent under
Section 228 of the Delaware General Corporation Law (the "Delaware Statute"), as
the sole stockholder of Pacific Sub, to the execution, delivery and performance
of the Pacific Sub Merger Agreement by Pacific Sub.

     SECTION 1.4  Exchange of Certificates.  Except as set forth above, from and
after the Merger Date, each holder of a certificate which immediately prior to
the Merger Date represented outstanding shares of Martin Marietta Common Stock,
Lockheed Common Stock or Martin Marietta Preferred Stock shall be entitled to
receive in exchange therefor, upon surrender thereof to an exchange agent to be
selected by the parties, a certificate or certificates representing the number
of shares of Parent Common Stock or Parent Preferred Stock into which such
holder's shares of Martin Marietta Common Stock, Lockheed Common Stock or Martin
Marietta Preferred Stock were converted. No holder of a certificate or
certificates which immediately prior to the Merger Date represented shares of
Martin Marietta Common Stock, Lockheed Common Stock or Martin Marietta Preferred
Stock shall be entitled to receive any dividend or other distribution from
Parent until surrender of such holder's certificate or certificates for a
certificate or certificates representing shares of Parent Common Stock (in the
case of holders of Lockheed Common Stock or Martin Marietta Common Stock) or
Parent Preferred Stock (in the case of holders of Martin Marietta Preferred
Stock). Upon such surrender, there shall be paid to the holder the amount of any
dividends or other distributions (without interest) which theretofore became
payable, but which were not paid by reason of the foregoing, with respect to the
number of whole shares of Parent Common Stock or Parent Preferred Stock, as the
case may be, represented by the certificates issued upon such surrender. From
and after the Merger Date, Parent shall, however, be entitled to treat such
certificates for shares of Martin Marietta Common Stock, Lockheed Common Stock
or Martin Marietta Preferred Stock which have not yet been surrendered for
exchange as evidencing the ownership of the number of shares of Parent Common
Stock or Parent Preferred Stock, as the case may be, into which the shares of
Martin Marietta Common Stock, Lockheed Common Stock or Martin Marietta Preferred
Stock represented by such certificates shall have been converted,
notwithstanding any failure to surrender such certificates. If any certificate
for shares of Parent Common Stock or Parent Preferred Stock, as the case may be,
is to be issued in a name other than that in which the certificate for shares of
Martin Marietta Common Stock, Lockheed Common Stock or Martin Marietta Preferred
Stock surrendered in exchange therefor is registered, it shall be a condition of
such issuance that the person requesting such issuance shall pay any transfer or
other tax required by reason of the issuance of certificates for such shares of
Parent Common Stock or Parent Preferred Stock, as the case may be, in a name
other than that of the registered holder of the certificate surrendered, or
shall establish to the satisfaction of Parent or its agent that such tax has
been paid or is not applicable. Notwithstanding the foregoing, none of Martin
Marietta, Lockheed or Parent shall be liable to any holder of shares of Martin
Marietta Common Stock, Lockheed Common Stock or Martin Marietta Preferred Stock
for any shares of Parent Common Stock or Parent Preferred Stock, as the case may
be (or dividends or distributions with respect thereto), delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
 
     SECTION 1.5  Cancellation of Parent Stock.  The shares of the capital stock
of Parent owned by Martin Marietta and Lockheed immediately prior to the Merger
Date will be cancelled immediately upon consummation of the Atlantic Sub Merger
and the Pacific Sub Merger, respectively. The Atlantic Sub Merger and the
Pacific Sub Merger are sometimes together referred to as the "Mergers" and the
Atlantic Sub Merger Agreement and the Pacific Sub Merger Agreement are sometimes
together referred to as the "Merger Agreements."

                              STOCKHOLDER APPROVAL
 
     Subject to the terms and conditions contained herein, this Agreement,
together with the Atlantic Sub Merger Agreement and the transactions
contemplated thereby, shall be submitted for approval to the holders of shares
of Martin Marietta Common Stock and Martin Marietta Preferred Stock, all of whom
shall vote together as a single class at a meeting to be duly held for this
purpose by Martin Marietta (the "Martin Marietta Meeting"), and this Agreement,
together with the Pacific Sub Merger Agreement, shall be submitted for adoption
and approval to the holders of shares of Lockheed Common Stock at a meeting to
be duly held for this purpose by Lockheed (the "Lockheed Meeting"). Martin
Marietta and Lockheed shall coordinate and cooperate with respect to the timing
of such meetings and shall endeavor to hold such meetings on the same day and as
soon as practicable after the date hereof. Subject to the applicable fiduciary
duties of
 
                                       I-3
<PAGE>   126
 
their respective directors, Martin Marietta and Lockheed shall recommend that
their respective stockholders approve this Agreement and the transactions
contemplated hereby and such recommendation shall be contained in the Joint
Proxy Statement referred to in Sections 4.11 and 5.11. On the first business day
on or by which (a) this Agreement and the Atlantic Sub Merger Agreement have
been duly approved by the requisite vote of the holders of shares of Martin
Marietta Common Stock and Martin Marietta Preferred Stock, (b) this Agreement
and the Pacific Sub Merger Agreement have been duly adopted and approved by the
requisite vote of the holders of shares of Lockheed Common Stock and (c) the
closing of the transactions contemplated by this Agreement and the Merger
Agreements shall have occurred, or such later date as shall be agreed upon by
Martin Marietta and Lockheed, Articles of Merger (in the case of the Atlantic
Sub Merger) and a Certificate of Merger (in the case of the Pacific Sub Merger)
relating to the Mergers shall be filed in accordance with the Maryland Statute
and the Delaware Statute, respectively, and the Mergers shall become effective
simultaneously in accordance with the terms of the Merger Agreements (such time
and date are referred to as the "Merger Date").
 
                                  ARTICLE III
 
                         BOARDS OF DIRECTORS OF PARENT,
                         MARTIN MARIETTA AND LOCKHEED;
                    OFFICERS OF MARTIN MARIETTA AND LOCKHEED
 
     It is the intent of the parties to this Agreement that Martin Marietta and
Lockheed, as subsidiaries of Parent, will each continue (so far as practicable
and consistent with the basic purposes of this Agreement) the separate
operations of their respective business enterprises, subject to the combining of
such operations and to such other organizational and structural changes as
management may from time to time deem appropriate. With that objective in mind,
Martin Marietta, Lockheed and Parent agree as follows:
 
     SECTION 3.1  Parent Board of Directors.  On the Merger Date, the number of
directors comprising the full Board of Directors of Parent shall be 24 (as
provided in Parent's Bylaws), composed as follows:
 
          (a) twelve directors shall be designated by Martin Marietta by its
     Board Nominating Committee; and
 
          (b) twelve directors shall be designated by Lockheed by its Board
     Nominating Committee.
 
It is the intent of the parties that membership on the major committees of
Parent's Board of Directors shall initially consist of an equal number of
designees of Martin Marietta and Lockheed.
 
     SECTION 3.2  Martin Marietta Board of Directors; Officers.  On the Merger
Date, the Board of Directors of Martin Marietta shall include those current
directors of Martin Marietta who are designated as such by the Chief Executive
Officer of Martin Marietta. The officers of Martin Marietta immediately prior to
the Merger Date will continue in such capacities immediately following the
Merger Date.
 
     SECTION 3.3  Lockheed Board of Directors; Officers.  On the Merger Date,
the Board of Directors of Lockheed shall include those current directors of
Lockheed who are designated as such by the Chief Executive Officer of Lockheed.

such capacities immediately following the Merger Date.
 
     SECTION 3.4  Parent Dividend.  It is the intention of the parties that the
initial quarterly dividend with respect to Parent stock shall be at the annual
rate of $1.40 per share, subject to approval and declaration by the Board of
Directors of Parent.

                                   ARTICLE IV
 
               REPRESENTATIONS AND WARRANTIES OF MARTIN MARIETTA
 
     Martin Marietta represents and warrants to, and agrees with, Lockheed as
follows (except as disclosed in a schedule dated the date hereof and furnished
to Lockheed, hereafter referred to as the "Martin Marietta Schedule"):
 
     SECTION 4.1  Organization, Qualification, Etc.  Martin Marietta is a
corporation duly organized, validly existing and in good standing under the laws
of its state of incorporation and has the corporate power and authority to own
its properties and assets and to carry on its business as it is now being
conducted and is duly qualified to do business and is in good standing in each
jurisdiction in which the ownership of its properties or the conduct of its
business requires such qualification, except for jurisdictions in which such
failure to be so qualified or to be in good standing would not, individually or
in the aggregate, have a material adverse effect on the business, results of
operations or financial condition of Martin Marietta and its Subsidiaries taken
as a whole. The copies of Martin Marietta's charter and bylaws which have been
delivered to Lockheed are complete and correct and in full force and effect on
the date hereof. Each of Martin Marietta's Significant Subsidiaries (as
hereinafter defined) is a corporation duly organized, validly existing and in
good standing under the laws of its jurisdiction of incorporation, has the
corporate power and authority to own its properties and to carry on its business
as it is now being conducted, and is duly qualified to do business and is in
good standing in each jurisdiction in which the ownership of its property or the
conduct of its business requires such qualification, except for jurisdictions in
which such failure to be so qualified or to be in good standing would not,
individually or in the aggregate, have a material adverse effect on the
business, results of operations or financial condition of Martin Marietta and
its Subsidiaries taken as a whole. All the outstanding shares of capital stock
of Martin Marietta's Significant Subsidiaries are validly issued, fully paid and
non-assessable and (except as set forth in the next sentence) are owned by
Martin Marietta, directly or indirectly, free and clear of all liens, claims,
charges or encumbrances, except for restrictions contained in credit agreements
and similar instruments to which Martin Marietta is a party under which no event
of default has occurred or arisen. Martin Marietta owns approximately 81% of the
outstanding shares of common stock of Martin Marietta Materials, Inc. There are
no existing options, rights of first refusal, preemptive rights, calls or
commitments of any character relating to the issued or unissued capital stock or
other securities of any Subsidiary of Martin Marietta other than rights of
refusal and preemptive rights held by Martin Marietta with respect to certain
Subsidiaries.
 
     SECTION 4.2  Capital Stock.  The authorized capital stock of Martin
Marietta consists of 550,000,000 shares, divided into 20,000,000 shares of
Series A Preferred Stock, par value $1.00 per share ("Martin Marietta Preferred
Stock"), 30,000,000 shares of Series Preferred Stock, par value $1.00 per share
("Martin Marietta Series Preferred Stock"), and 500,000,000 shares of common
stock, par value $1.00 per share ("Martin Marietta Common Stock"). As of July
31, 1994, 20,000,000 shares of Martin Marietta Preferred Stock, no shares of
Martin Marietta Series Preferred Stock and 95,948,640 shares of Martin Marietta
Common Stock were outstanding. All the outstanding shares of capital stock of
Martin Marietta have been validly issued and are fully paid and nonassessable.
As of July 31, 1994, there were no outstanding subscriptions, options, warrants,
rights or other arrangements or commitments obligating Martin Marietta to issue
any shares of its capital stock ("Martin Marietta Options") other than:
 
          (a) upon conversion of the Martin Marietta Preferred Stock;
 
          (b) options to acquire 4,706,450 shares of Martin Marietta Common
     Stock granted on or prior to July 31, 1994 pursuant to employee incentive
     and benefit plans; and
 
          (c) Martin Marietta's dividend reinvestment plan.
 
Since July 31, 1994 (A) no shares of Martin Marietta Common Stock or Martin
Marietta Preferred Stock have been issued except issuances of Martin Marietta
Common Stock upon the exercise of Martin Marietta Options referred to in clause
(b) above, and (B) no Martin Marietta Options have been authorized, issued or
granted, except pursuant to Martin Marietta's Shareholder Rights Agreement,
dated as of August 29, 1994, with First Chicago Trust Company of New York (the
"Martin Marietta Rights Plan").

     SECTION 4.3  Corporate Authority Relative to this Agreement; No
Violation.  Martin Marietta has the corporate power to enter into this Agreement
and the Atlantic Sub Merger Agreement, and to carry out its obligations
hereunder and thereunder. The execution and delivery of this Agreement and the
Atlantic Sub Merger Agreement and the consummation of the transactions
contemplated hereby and thereby have been duly and validly authorized by the
Board of Directors of Martin Marietta and, except for the approval of its
stockholders, no other corporate proceedings on the part of Martin Marietta are
necessary to authorize this Agreement, the Atlantic Sub Merger Agreement and the
transactions contemplated hereby and thereby. The Board of Directors of Martin
Marietta has determined that the transactions contemplated by this Agreement and
the Atlantic Sub Merger Agreement are in the best interests of Martin Marietta
and its stockholders and to recommend to such stockholders that they vote in
favor thereof. This Agreement and the Atlantic Sub Merger Agreement have been
duly and validly executed and delivered by Martin Marietta and, assuming this
Agreement and the Atlantic Sub Merger Agreement constitute valid and binding
Agreements of the other parties hereto and thereto, this Agreement and the
Atlantic Sub Merger Agreement constitute valid and binding agreements of Martin
Marietta, enforceable against Martin Marietta in accordance with their
respective terms (except insofar as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
creditors' rights generally, or by principles governing the availability of
equitable remedies). Martin Marietta is not subject to or obligated under any
charter, bylaw or contract provision or any license, franchise or permit, or
subject to any order or decree, which would be breached or violated by its
executing or, subject to the approval of its stockholders, carrying out this
Agreement or the Atlantic Sub Merger Agreement, except for any breaches or
violations which individually or in the aggregate would not have a material
adverse effect on the business, results of operations or financial condition of
Martin Marietta and its Subsidiaries taken as a whole. Other than in connection
with or in compliance with the provisions of the Maryland Statute, the
Securities Act of 1933, as amended (the "Securities Act"), the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 (the "HSR Act"), Section 4043 of ERISA (as
hereinafter defined), any non-United States competition, antitrust and
investment laws, and the securities or blue sky laws of the various states
(collectively, the "Martin Marietta Required Statutory Approvals"), no
authorization, consent or approval of, or filing with, any governmental body or
authority is necessary for the consummation by Martin Marietta of the
transactions contemplated by this Agreement and the Atlantic Sub Merger
Agreement, except for such authorizations, consents, approvals or filings, the
failure to obtain or make which would not have a material adverse effect on the
business, results of operations or financial condition of Martin Marietta and
its Subsidiaries taken as a whole or on the consummation of the transactions
contemplated hereby.
 
     SECTION 4.4  Reports and Financial Statements.  Martin Marietta has
previously furnished to Lockheed true and complete copies of:
 
          (a) Martin Marietta's Annual Reports on Form 10-K filed with the
     Securities and Exchange Commission (the "SEC") for each of the years ended
     December 31, 1991 through 1993;
 
          (b) Martin Marietta's Quarterly Reports on Form 10-Q filed with the
     SEC for the quarters ended March 31 and June 30, 1994;
 
          (c) each definitive proxy statement filed by Martin Marietta with the
     SEC since December 31, 1991;
 
          (d) each final prospectus filed by Martin Marietta with the SEC since
     December 31, 1991, other than prospectuses contained in filings on Form S-8
     and filings with respect to Martin Marietta's dividend reinvestment plan on
     Form S-3;
 
          (e) all Current Reports on Form 8-K filed by Martin Marietta with the
     SEC since December 31, 1993; and
 
          (f) Reports on Form 11-K filed with the SEC with respect to employee
     benefit plans of Martin Marietta or any of its Subsidiaries since December
     31, 1993.
 
                                       I-6
<PAGE>   129
 
As of their respective dates, such reports, proxy statements and prospectuses
did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The audited consolidated financial statements and unaudited
consolidated interim financial statements included in such reports, proxy
statements and prospectuses (including any related notes and schedules) fairly
present the financial position of Martin Marietta and its consolidated
Subsidiaries as of the dates thereof and the results of operations and changes
in financial position or other information included therein for the periods or
as of the dates then ended (subject, where appropriate, to normal year-end
accrual adjustments), in each case in accordance with past practice and
generally accepted accounting principles in the United States ("GAAP")
consistently applied during the periods involved (except as otherwise disclosed
in the notes thereto). Since December 31, 1991, Martin Marietta has timely filed
all reports, registration statements and other filings required to be filed with
the SEC under the rules and regulations of the SEC. For purposes of this Section
4.4, the term "Martin Marietta" shall include "Martin Marietta Technologies,
Inc." and "Martin Marietta Materials, Inc.".
 
     SECTION 4.5 No Undisclosed Liabilities.  As of June 30, 1994, neither
Martin Marietta nor any of its Subsidiaries had any liabilities or obligations
of any nature, whether or not accrued, contingent or otherwise, that would be
required by GAAP to be reflected on a consolidated balance sheet of Martin
Marietta and its Subsidiaries (including the notes thereto), except (a)
liabilities or obligations reflected in any of the documents referred to in
Section 4.4 and (b) liabilities or obligations which would not have,
individually or in the aggregate, a material adverse effect on the business,
results of operations or financial condition of Martin Marietta and its
Subsidiaries taken as a whole.
 
     SECTION 4.6 No Violation of Law.  The businesses of Martin Marietta and its
Subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any governmental entity (provided that no representation or
warranty is made in this Section 4.6 with respect to Environmental Laws (as
defined in Section 4.7)) except (a) as described in any of the documents
referred to in Section 4.4 and (b) for violations or possible violations which
individually or in the aggregate do not, and, insofar as reasonably can be
foreseen, in the future would not, have a material adverse effect on the
business, results of operations or financial condition of Martin Marietta and
its Subsidiaries taken as a whole.
 
     SECTION 4.7 Environmental Laws and Regulations.  Except as described in any
of the documents referred to in Section 4.4, (i) Martin Marietta and each of its
Subsidiaries is in material compliance with all applicable federal, state and
local laws and regulations relating to pollution or protection of human health
or the environment (including, without limitation, ambient air, surface water,
ground water, land surface or subsurface strata) (collectively, "Environmental
Laws"), except for non-compliance that individually or in the aggregate do not,
and, insofar as reasonably can be foreseen, in the future would not, have a
material adverse effect on the business, results of operations or financial
condition of Martin Marietta and its Subsidiaries taken as a whole, which
compliance includes, but is not limited to, the possession by Martin Marietta
and its Subsidiaries of all material permits and other governmental
authorizations required under applicable Environmental Laws, and compliance with
the terms and conditions thereof; (ii) neither Martin Marietta nor any of its
Subsidiaries has received written notice of, or, to the knowledge of Martin
Marietta, is the subject of, any actions, causes of action, claims,
investigations, demands or notices by any person or entity alleging liability
under or non-compliance with any Environmental Law ("Environmental Claims") that
individually or in the aggregate would have a material adverse effect on the
business, results of operations or financial condition of Martin Marietta and
its Subsidiaries taken as a whole; and (iii) to the knowledge of Martin
Marietta, there are no circumstances that are reasonably likely to prevent or
interfere with such material compliance in the future.
 
     SECTION 4.8 No Undisclosed Employee Benefit Plan Liabilities.  All
"employee benefit plans," as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), maintained or contributed to
by Martin Marietta or its Subsidiaries are in compliance with all applicable
provisions of ERISA and the Internal Revenue Code of 1986, as amended (the
"Code"), and Martin Marietta and its Subsidiaries do not have any liabilities or
obligations with respect to any such employee benefit plans, whether or not
accrued, contingent or otherwise, except (a) as described in any of the
 
                                       I-7
<PAGE>   130
 
documents referred to in Section 4.4 and (b) for instances of non-compliance or
liabilities or obligations that would not have, individually or in the
aggregate, a material adverse effect on the business, results of operations or
financial condition of Martin Marietta and its Subsidiaries taken as a whole.
 
     SECTION 4.9 Absence of Certain Changes or Events.  Other than as disclosed
in the documents referred to in Section 4.4, since December 31, 1993 there has

          (a) no material investigation or review by any governmental entity

     indicated to Martin Marietta an intention to conduct the same; and
 
          (b) there are no actions, suits or proceedings pending (or, to Martin
     Marietta's knowledge, threatened) against or affecting Martin Marietta or
     its Subsidiaries at law or in equity, or before any federal, state,
     municipal or other governmental department, commission, board, bureau,
     agency or instrumentality which, either individually or in the aggregate,
     are reasonably likely to result in any material adverse change in the
     business, prospects, results of operations or financial condition of Martin
     Marietta and its Subsidiaries taken as a whole.
 
     SECTION 4.11 Joint Proxy Statement; Registration Statement; Other

"Business Combinations" of the Accounting Principles Board of the American
Institute of Certified Public Accountants, as amended by applicable

used in this Agreement (except as specifically otherwise defined), the term
"affiliate" shall mean, as to any person, any other person which directly or
indirectly controls, or is under common control with, or is controlled by, such

management or policies (whether through ownership of securities or partnership
or other ownership interests, by contract or otherwise).
 
     SECTION 4.13 Martin Marietta Rights Plan.  Under the terms of the Martin
Marietta Rights Plan, the transactions contemplated by this Agreement will not
cause a Distribution Date to occur or cause the rights issued pursuant to the
Martin Marietta Rights Plan to become exercisable, and as a result of the terms
of the Martin Marietta Rights Plan such rights will be cancelled and cease to
exist upon consummation of the transactions contemplated hereby.

taxes, interest, additions, and penalties due with respect to completed and

benefit programs, Martin Marietta's dividend reinvestment plan or otherwise in

                   REPRESENTATIONS AND WARRANTIES OF LOCKHEED
 
     Lockheed represents and warrants to, and agrees with, Martin Marietta as
follows (except as disclosed in a schedule dated the date hereof and furnished
to Martin Marietta, hereafter referred to as the "Lockheed Schedule"):
 
     SECTION 5.1 Organization, Qualification, Etc.  Lockheed is a corporation
duly organized, validly existing and in good standing under the laws of the
state of its incorporation and has the corporate power and authority to own its
properties and assets and to carry on its business as it is now being conducted
and is duly qualified to do business and is in good standing in each
jurisdiction in which the ownership of its properties or the conduct of its
business requires such qualification, except for jurisdictions in which such
failure to be so qualified or to be in good standing would not, individually or
in the aggregate, have a material adverse effect on the business, results of
operations or financial condition of Lockheed and its Subsidiaries taken as a
whole. The copies of Lockheed's certificate of incorporation and bylaws which
have been delivered to Martin Marietta are complete and correct and in full
force and effect on the date hereof. Each of Lockheed's Significant Subsidiaries
is a corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of incorporation, has the corporate power and authority
to own its properties and to carry on its business as it is now being conducted,
and is duly qualified to do business and is in good standing in each
jurisdiction in which the ownership of its property or the conduct of its
business requires such qualification, except for jurisdictions in which such
failure to be so qualified or to be in good standing would not, individually or
in the aggregate, have a material adverse effect on the business, results of
operations or financial condition of Lockheed and its Subsidiaries taken as a
whole. All the outstanding shares of capital stock of Lockheed's
 
                                       I-9
<PAGE>   132
 
Significant Subsidiaries are validly issued, fully paid and non-assessable and
are owned by Lockheed, directly or indirectly, free and clear of all liens,
claims charges or encumbrances, except for restrictions contained in credit
agreements and similar instruments to which Lockheed is a party under which no
event of default has occurred or arisen. There are no existing options, rights
of first refusal, preemptive rights, calls or commitments of any character
relating to the issued or unissued capital stock or other securities of any
Subsidiary of Lockheed.
 
     SECTION 5.2  Capital Stock.  The authorized capital stock of Lockheed
consists of 100,000,000 shares of common stock, par value $1.00 per share
("Lockheed Common Stock"), and 2,500,000 shares of Preferred Stock, par value
$1.00 per share ("Lockheed Preferred Stock"), of which 1,000,000 shares were
designated as Series A Junior Participating Preferred Stock ("Lockheed Series A
Preferred"). As of July 31, 1994, 62,867,345 shares of Lockheed Common Stock
(excluding 9,775,996 shares held in Lockheed's treasury) and no shares of
Lockheed Preferred Stock were issued and outstanding. All the outstanding shares
of Lockheed Common Stock have been validly issued and are fully paid and
nonassessable. As of July 31, 1994, there were no outstanding subscriptions,
options, warrants, rights or other arrangements or commitments obligating
Lockheed to issue any shares of its capital stock ("Lockheed Options") other
than:
 
          (a) rights to acquire shares of Lockheed Series A Preferred pursuant
     to Lockheed's Shareholder Rights Agreement, dated as of December 8, 1986,
     with First Interstate Bank, Ltd., as amended (the "Lockheed Rights Plan");
     and
 
          (b) options to acquire 3,287,077 shares of Lockheed Common Stock
     granted on or prior to July 31, 1994 pursuant to employee incentive and
     benefit plans.
 
Since July 31, 1994 (A) no shares of Lockheed Common Stock have been issued
except issuances of Lockheed Common Stock upon the exercise of Lockheed Options
referred to in clause (b) above, and (B) except for an option grant relating to
1,500 shares, no Lockheed Options have been authorized, issued or granted.
 
     SECTION 5.3  Corporate Authority Relative to this Agreement; No
Violation.  Lockheed has the corporate power to enter into this Agreement and
the Pacific Sub Merger Agreement, and to carry out its obligations hereunder and
thereunder. The execution and delivery of this Agreement and the Pacific Sub
Merger Agreement, and the consummation of the transactions contemplated hereby
and thereby have been duly and validly authorized by the Board of Directors of
Lockheed and, except for the approval of its stockholders, no other corporate
proceedings on the part of Lockheed are necessary to authorize this Agreement,
the Pacific Sub Merger Agreement and the transactions contemplated hereby and
thereby. The Board of Directors of Lockheed has determined that the transactions
contemplated by this Agreement and the Pacific Sub Merger Agreement are in the
best interests of Lockheed and its stockholders and to recommend to such
stockholders that they vote in favor thereof. This Agreement and the Pacific Sub
Merger Agreement have been duly and validly executed and delivered by Lockheed
and, assuming this Agreement and the Pacific Sub Merger Agreement constitute
valid and binding agreements of the other parties hereto and thereto, this
Agreement and the Pacific Sub Merger constitute valid and binding agreements of
Lockheed, enforceable against Lockheed in accordance with their respective terms
(except insofar as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally, or by principles governing the availability of equitable
remedies). Lockheed is not subject to or obligated under any charter, by-law or
contract provision or any license, franchise or permit, or subject to any order
or decree, which would be breached or violated by its executing or, subject to
the approval of its stockholders, carrying out this Agreement or the Pacific Sub
Merger Agreement, except for any breaches or violations which individually or in
the aggregate would not have a material adverse effect on the business, results
of operations or financial condition of Lockheed and its Subsidiaries taken as a
whole. Other than in connection with or in compliance with the provisions of the
Delaware Statute, the Securities Act, the Exchange Act, the HSR Act, Section
4043 of ERISA, any non-United States competition, antitrust and investment laws,
and the securities or blue sky laws of the various states (collectively, the
"Lockheed Required Statutory Approvals"), no authorization, consent or approval
of, or filing with, any governmental body or authority is necessary for the
consummation by Lockheed of the transactions contemplated by this
 
                                      I-10
<PAGE>   133
 
Agreement and the Pacific Sub Merger Agreement, except for such authorizations,
consents, approvals or filings, the failure to obtain or make which would not
have a material adverse effect on the business, results of operations or
financial condition of Lockheed and its Subsidiaries taken as a whole or on the
consummation of the transaction contemplated hereby.
 
     SECTION 5.4  Reports and Financial Statements.  Lockheed has previously
furnished to Martin Marietta true and complete copies of:
 
          (a) Lockheed's Annual Reports on Form 10-K filed with the SEC for each
     of the years ended December 31, 1991 through 1993;
 
          (b) Lockheed's Quarterly Reports on Form 10-Q filed with the SEC for
     the quarters ended March 31 and June 30, 1994;

     benefit plans of Lockheed or any of its Subsidiaries since December 31,
     1993.
 
As of their respective dates, such reports, proxy statements and prospectuses
did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The audited consolidated financial statements and unaudited
consolidated interim financial statements included in such reports, proxy
statements and prospectuses (including any related notes and schedules) fairly
present the financial position of Lockheed and its consolidated Subsidiaries as
of the dates thereof and the results of operations and changes in financial
position or other information included therein for the periods or as of the
dates then ended (subject, where appropriate, to normal year-end accrual
adjustments), in each case in accordance with past practice and GAAP
consistently applied during the periods involved (except as otherwise disclosed
in the notes thereto). Since December 31, 1991, Lockheed has timely filed all
reports, registration statements and other filings required to be filed with the
SEC under the rules and regulations of the SEC.
 
     SECTION 5.5  No Undisclosed Liabilities.  As of June 30, 1994, neither
Lockheed nor any of its Subsidiaries had any liabilities or obligations of any
nature, whether or not accrued, contingent or otherwise, that would be required
by GAAP to be reflected on a consolidated balance sheet of Lockheed and its
Subsidiaries (including the notes thereto), except (a) liabilities or
obligations reflected in any of the documents referred to in Section 5.4 and (b)
liabilities or obligations, which would not have, individually or in the
aggregate, a material adverse effect on the business, results of operations or
financial condition of Lockheed and its Subsidiaries taken as a whole.
 
     SECTION 5.6  No Violation of Law.  The businesses of Lockheed and its
Subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any governmental entity (provided that no representation or
warranty is made in this Section 5.6 with respect to Environmental Laws) except
(a) as described in any of the documents referred to in Section 5.4, and (b) for
violations or possible violations which individually or in the aggregate do not,
and, insofar as reasonably can be foreseen, in the future would not, have a
material adverse effect on the business, results of operations or financial
condition of Lockheed and its Subsidiaries taken as a whole.
 
     SECTION 5.7  Environmental Laws and Regulations.  Except as described in
any of the documents referred to in Section 5.4, (i) Lockheed and each of its
Subsidiaries is in material compliance with all applicable Environmental Laws,
except for non-compliance that individually or in the aggregate do not, and,
insofar as reasonably can be foreseen, in the future would not, have a material
adverse effect on the business, results of operations or financial condition of
Lockheed and its Subsidiaries taken as a whole, which
 
                                      I-11
<PAGE>   134
 
compliance includes, but is not limited to, the possession by Lockheed and its
Subsidiaries of all material permits and other governmental authorizations
required under applicable Environmental Laws, and compliance with the terms and
conditions thereof; (ii) neither Lockheed nor any of its Subsidiaries has
received written notice of, or, to the knowledge of Lockheed, is the subject of,
any Environmental Claims that individually or in the aggregate would have a
material adverse effect on the business, results of operations or financial
condition of Lockheed and its Subsidiaries taken as a whole; and (iii) to the
knowledge of Lockheed, there are no circumstances that are reasonably likely to
prevent or interfere with such material compliance in the future.
 
     SECTION 5.8  No Undisclosed Employee Benefit Plan Liabilities.  All
"employee benefit plans," as defined in Section 3(3) of ERISA, maintained or
contributed to by Lockheed or its Subsidiaries are in compliance with all
applicable provisions of ERISA and the Code, and Lockheed and its Subsidiaries
do not have any liabilities or obligations with respect to any such employee
benefit plans, whether or not accrued, contingent or otherwise, except (a) as
described in any of the documents referred to in Section 5.4 and (b) for
instances of non-compliance or liabilities or obligations that would not have,
individually or in the aggregate, a material adverse effect on the business,
results of operations or financial condition of Lockheed and its Subsidiaries
taken as a whole.
 
     SECTION 5.9  Absence of Certain Changes or Events.  Other than as disclosed
in the documents referred to in Section 5.4, since December 31, 1993 there has
been no material adverse change in the business, prospects, results of
operations or financial condition of Lockheed and its Subsidiaries taken as a
whole.
 
     SECTION 5.10  Investigations; Litigation.  Except as described in any of
the documents referred to in Section 5.4:
 
          (a) no material investigation or review by any governmental entity
     with respect to Lockheed or any of its Subsidiaries is pending (or, to
     Lockheed's knowledge, threatened), nor has any governmental entity
     indicated to Lockheed an intention to conduct the same; and
 
          (b) there are no actions, suits or proceedings pending (or, to
     Lockheed's knowledge, threatened) against or affecting Lockheed or its
     Subsidiaries at law or in equity, or before any federal, state, municipal
     or other governmental department, commission, board, bureau, agency or
     instrumentality which, either individually or in the aggregate, are
     reasonably likely to result in any material adverse change in the business,
     prospects, results of operations or financial condition of Lockheed and its
     Subsidiaries taken as a whole.
 
     SECTION 5.11  Joint Proxy Statement; Registration Statement; Other
Information.  None of the information with respect to Lockheed or its
Subsidiaries or the Pacific Sub Merger to be included in the Joint Proxy
Statement or the Registration Statement will, in the case of the Joint Proxy
Statement or any amendments thereof or supplements thereto, at the time of the
mailing of the Joint Proxy Statement or any amendments or supplements thereto,
and at the time of the Lockheed Meeting or, in the case of the Registration
Statement, at the time it becomes effective, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading. The Joint Proxy
Statement will comply as to form in all material respects with the provisions of
the Exchange Act and the rules and regulations promulgated thereunder, except
that no representation is made by Lockheed with respect to information supplied
in writing by Martin Marietta or any affiliate of Martin Marietta specifically
for inclusion in the Joint Proxy Statement.
 
     SECTION 5.12  Accounting Matters.  Neither Lockheed nor, to its best
knowledge, any of its affiliates has taken or agreed to take any action that
would prevent Parent from accounting for the transactions to be effected
pursuant to Article I of this Agreement in accordance with the pooling of
interests method of accounting under the requirements of APB No. 16.
 
     SECTION 5.13  Lockheed Rights Plan.  Under the terms of the Lockheed Rights

                                      I-12
<PAGE>   135
 
as a result of the terms of the Lockheed Rights Plan and the Pacific Sub Merger
such rights will be cancelled and cease to exist.
 
     SECTION 5.14  Ownership of Martin Marietta Stock.  On the date hereof
Lockheed and its Subsidiaries do not beneficially own in excess of 1,000 shares
of Martin Marietta Common Stock in the aggregate (exclusive of any shares owned
by Lockheed's employee benefit plans) and is not an "interested stockholder" or
an affiliate of an "interested stockholder" of Martin Marietta within the
meaning of Section 3-601(j) of the Maryland Statute.
 
     SECTION 5.15  Tax Matters.  (a) All federal, state, local, and foreign tax
returns required to be filed by or on behalf of Lockheed and each of its
Subsidiaries have been timely filed, and all returns filed are complete and
accurate to the knowledge of Lockheed. All taxes shown on filed returns have
been paid or adequate provision for the payment of all such taxes has been made.
As of the date of this Agreement, there is no audit examination, deficiency,
refund litigation, proposed adjustment or matter in controversy with respect to
any taxes that may reasonably be expected to result in a determination
materially adverse to Lockheed or any of its Subsidiaries, except as adequately
reserved against in the most recent financial statements contained in the
documents referred to in Section 5.4. All assessments for taxes, interest,
additions, and penalties due with respect to completed and settled examinations
or concluded litigation have been paid.

securityholders of Lockheed, Martin Marietta or Parent in connection with the

business, the management of Lockheed has no plan or intention for Parent to
redeem or otherwise reacquire any Parent Preferred Stock or Parent Common Stock

and the management of Lockheed has no plan or intention to terminate the
existence of Parent or to merge Parent with any other corporation.

percent of the fair market value of its net assets and at least 70 percent of
the fair market value of its gross assets and at least 90 percent of the fair
market value of Pacific Sub's net assets and at least 70 percent of the fair
market value of Pacific Sub's gross assets held immediately prior to such
Merger. For purposes of this representation, amounts used by Lockheed or Pacific
Sub to pay reorganization expenses, and all redemptions and distributions
(except for regular, normal dividends) made by Lockheed will be included as
assets held by Lockheed or Pacific Sub, respectively, immediately prior to the
Pacific Sub Merger.
 
     (d) Lockheed has no plan or intention to issue additional shares of its
stock following the Pacific Sub Merger that would result in Parent's ceasing to
own all the outstanding shares of stock of Lockheed.
 
     (e) Lockheed is not aware of any plan or intention of Parent: to liquidate
Lockheed; to merge Lockheed with or into another corporation; to sell or
otherwise dispose of the stock of Lockheed except for transfers of stock to
corporations controlled by Parent; to cause Lockheed to sell or otherwise
dispose of any of its assets or of any of the assets acquired from Pacific Sub,
except for dispositions made in the ordinary course of business or transfers of

     the ordinary course of business and consistent with past practice covering
     not in excess of 25,000 shares of Martin Marietta Common Stock or 25,000
     shares of Lockheed Common Stock;
 
          (k) shall not, and shall not permit any of their respective

     ordinary course of business or Martin Marietta's dividend reinvestment
     plan, purchase or redeem any shares of its capital stock;

<PAGE>   137
 
          (l) shall not, and shall not permit any of their respective
     Subsidiaries to, take any actions which would, or would be reasonably
     likely to, prevent Parent from accounting for the transactions to be
     effected pursuant to Article I of this Agreement in accordance with the
     pooling of interests method of accounting under the requirements of APB No.
     16;
 
          (m) shall not, and shall not permit any of their respective
     Subsidiaries to, except as contemplated by Section 6.5, amend in any
     significant respect the terms of their respective employee benefit plans,

     arrangements in existence on the date hereof, or adopt any new employee
     benefit plans, programs or arrangements or any severance or similar
     agreements or arrangements;
 
          (n) shall not, and shall not permit any of their respective
     Subsidiaries to, (i) enter into any material loan agreement or (ii) enter
     into or bid with respect to any contract that is expected to result in a
     material loss; and
 
          (o) shall not, and shall not permit any of their respective
     Subsidiaries to, agree in writing or otherwise, to take any of the
     foregoing actions or any action which would make any representation or
     warranty in Articles IV and V hereof untrue or incorrect.
 
For purposes of this Section 6.1, Martin Marietta Materials, Inc. or any of its
Subsidiaries shall not be considered to be a Subsidiary of Martin Marietta.
 
     SECTION 6.2 Investigation.  Each of Martin Marietta and Lockheed shall
afford to one another and to one another's officers, employees, accountants,
counsel and other authorized representatives full and complete access during
normal business hours, throughout the period prior to the earlier of the Merger
Date or the Termination Date, to its and its Subsidiaries' plants, properties,
contracts, commitments, books, and records (including but not limited to tax
returns) and any report, schedule or other document filed or received by it
pursuant to the requirements of federal or state securities laws, and shall use
their reasonable efforts to cause their respective representatives to furnish
promptly to one another such additional financial and operating data and other
information as to its and its Subsidiaries' respective businesses and properties
as the other or its duly authorized representatives may from time to time
reasonably request. The parties hereby agree that each of them will treat any
such information in accordance with the Confidentiality Agreement, dated March
29, 1994, between Martin Marietta and Lockheed (the "Confidentiality
Agreement"), and, subject to applicable law, will not disclose any such
information to any other party. Notwithstanding any provision of this Agreement
to the contrary, no party shall be obligated to make any disclosure in violation
of applicable laws or regulations, including any such laws or regulations
pertaining to the treatment of classified information. If for any reason the
Mergers are not consummated, each of Martin Marietta and Lockheed shall return
or shall cause to be returned all information (and any copies thereof or
extracts therefrom) obtained by it or its representatives pursuant to this
Agreement or in connection with the negotiations hereof to the other party and
will thereafter continue to treat as confidential all such information and shall
not use, or knowingly permit any other party to use, any such information.
 
     SECTION 6.3  Cooperation.  Martin Marietta and Lockheed shall together, or
pursuant to an allocation of responsibility to be agreed upon between them:
 
          (a) prepare and file with the SEC as soon as is reasonably practicable
     the Joint Proxy Statement and a registration statement of Parent (the
     "Registration Statement") with respect to the transactions contemplated by
     this Agreement, and use their reasonable efforts to have the Joint Proxy
     Statement cleared by the SEC under the Exchange Act and the Registration
     Statement declared effective by the SEC under the Securities Act;
 
          (b) as soon as is reasonably practicable take all such action as may
     be required under state blue sky or securities laws in connection with the
     transactions contemplated by this Agreement;
 
          (c) cooperate with one another in determining whether any filings are
     required to be made with or consents required to be obtained from, any
     third party or governmental authority in any jurisdiction prior to the
     Merger Date in connection with the consummation of the transactions
     contemplated in this
 
                                      I-15
<PAGE>   138
 
     Agreement and cooperate in making any such filings promptly and in seeking
     to obtain timely any such consents;
 
          (d) promptly make application to the NYSE and such other stock
     exchanges as shall be agreed upon for the listing of the Parent Common
     Stock and use its reasonable efforts to list such stock on the NYSE or such
     other exchanges;
 
          (e) promptly make their respective filings and any other required or
     requested submissions under the HSR Act; and
 
          (f) cooperate with one another in order to lift any injunctions or
     remove any other impediment to the consummation of the transactions
     contemplated herein, except that no party shall be required to agree to the
     divestiture of any of its or the other party's material assets or to other
     materially onerous conditions in order to obtain any governmental approval.
 
Subject to the limitations contained in Section 6.2, Martin Marietta and
Lockheed shall each furnish to one another and to one another's counsel all such
information as may be required in order to effect the foregoing actions and each
represents and warrants to the other that no information furnished by it in
connection with such actions or otherwise in connection with the consummation of
the transactions contemplated by this Agreement will contain any untrue
statement of a material fact or omit to state a material fact required to be
stated in order to make any information so furnished, in light of the
circumstances under which it is so furnished, not misleading.
 
     SECTION 6.4  Affiliate Agreements.  Each of Martin Marietta and Lockheed
(each of which is referred to in this Section 6.4 as a "Subject Company") shall,
prior to the Merger Date, cause to be delivered to the other a list, reviewed by
its counsel, identifying all persons who are, in its opinion, at the time of the
meeting of the Subject Company's stockholders to be held in accordance with
Article II, "affiliates" of the Subject Company for purposes of Rule 145
promulgated by the SEC under the Securities Act. Each Subject Company shall
furnish such information and documents as the other may reasonably request for
the purpose of reviewing such list. Each Subject Company shall use its
reasonable efforts to cause each person who is identified as an "affiliate" in
the list furnished pursuant to this Section 6.4 to execute a written agreement
on or prior to the Merger Date, in a form satisfactory to the other (an
"Affiliate Agreement"), that such person (a) will not offer or sell or otherwise
dispose of any of the shares of Parent Common Stock issued to such person
pursuant to the Mergers in violation of the Securities Act or the rules or
regulations promulgated by the SEC thereunder, and (b) will not offer or sell or
otherwise dispose of any of the shares of Martin Marietta Common Stock, Martin
Marietta Preferred Stock, Lockheed Common Stock, Parent Common Stock or Parent
Preferred Stock in a manner or at a time that will disqualify Parent from
accounting for the transactions contemplated by this Agreement in accordance
with the pooling of interests method of accounting.
 
     SECTION 6.5  Employee Stock Options, Incentive and Benefit Plans.  (a)
Simultaneously with the Atlantic Sub Merger, (i) each outstanding option to
purchase or acquire a share of Martin Marietta Common Stock under option plans
presently maintained by Martin Marietta ("Martin Marietta Option Plans") shall
be converted into an option to purchase that number of shares of Parent Common
Stock which could have been obtained upon the exercise of each such option at
the same exercise price, and all references in each such option to Martin
Marietta shall be deemed to refer to Parent, where appropriate, (ii) each
outstanding stock appreciation right under the Martin Marietta Option Plans
("Martin Marietta SAR") to receive a cash payment based on the Martin Marietta
Common Stock shall be converted into a stock appreciation right to receive a
cash payment based on the Parent Common Stock, for the same number of shares and
at the same base price as applied to the Martin Marietta SAR, and all references
in each Martin Marietta SAR to Martin Marietta shall be deemed to refer to
Parent, where appropriate, (iii) Parent shall assume the obligations of Martin
Marietta under the Martin Marietta Option Plans and (iv) each outstanding award
made pursuant to Martin Marietta's Amended and Restated Long Term Performance
Incentive Compensation Plan and its predecessor plans shall be amended or
converted into a similar instrument of Parent, in either case with such
adjustments to the terms of such awards, including but not limited to, the
formula setting forth the redemption value of such awards as are appropriate to
preserve the value inherent in such awards with no detrimental
 
                                      I-16
<PAGE>   139
 
effects on the holders thereof without their consent. Subject to stockholder
approval of the 1994 Parent Stock Plan (as hereinafter defined), no additional
options or awards shall be granted pursuant to the Martin Marietta Option Plans
after the Atlantic Sub Merger.
 
     (b) Simultaneously with the Pacific Sub Merger, (i) each outstanding option
(and related stock appreciation right ("Lockheed SAR"), if any) to purchase or
acquire a share of Lockheed Common Stock under option plans presently maintained
by Lockheed ("Lockheed Option Plans") shall be converted into an option
(together with a related stock appreciation right of Parent, if applicable), to
purchase 1.63 times the number of shares of Parent Common Stock which could have
been obtained upon the exercise of each such option, at an exercise price per
share equal to the exercise price for each such share of Lockheed Common Stock
subject to an option (and related Lockheed SAR, if any) under the Lockheed
Option Plans divided by 1.63, and all references in each such option (and
related Lockheed SAR, if any) to Lockheed shall be deemed to refer to Parent,
where appropriate, and (ii) Parent shall assume the obligations of Lockheed
under the Lockheed Option Plans. Subject to stockholder approval of the 1994
Parent Stock Plan, no additional options or awards shall be granted pursuant to
the Lockheed Option Plans after the Pacific Sub Merger.
 
     (c) Martin Marietta and Lockheed agree that effective as of the Merger
Date, and subject to approval by the stockholders of Martin Marietta and
Lockheed, Parent shall adopt an omnibus securities award plan (the "1994 Parent
Stock Plan") for the purpose of granting stock options, restricted stock, stock
appreciation rights or other stock-based incentive awards to such employees of
Parent, Martin Marietta and Lockheed, and their respective Subsidiaries, in such
amounts and upon such terms and conditions as the Compensation Committee of the
Board of Directors of Parent shall, in its sole discretion, determine (subject
to the provisions of the 1994 Parent Stock Plan).
 
     (d) Martin Marietta and Lockheed agree that each of their respective stock
option, employee incentive and benefit plans, programs and arrangements (in
addition to those for non-employee directors) and in the case of Martin
Marietta, its dividend reinvestment plan, shall be amended, to the extent
necessary or appropriate, to reflect the transactions contemplated by this
Agreement, including, but not limited to, (i) the conversion of shares of Martin
Marietta Common Stock or Lockheed Common Stock held pursuant to such benefit
plans, programs or arrangements into shares of Parent Common Stock on a basis
consistent with the transactions contemplated by this Agreement, and (ii) the
appointment of appropriate committees consisting of directors of Martin Marietta
or Lockheed, as the case may be, or Parent, if appropriate, who are not
participants in such plans, programs or arrangements. The actions to be taken by
Martin Marietta and Lockheed pursuant to this section 6.5(d) shall include the
submission of the amendments to the plans, programs or arrangements referred to
herein to their respective stockholders at the special meetings to consider this
Agreement and the Merger Agreements, if such submission is determined to be
necessary or advisable by counsel to Martin Marietta or Lockheed after
consultation with one another; provided, however, that such approval shall not
be a condition to the consummation of the Mergers.
 
     (e) Parent shall (i) reserve for issuance the number of shares of Parent
Common Stock that will become subject to the benefit plans, programs and
agreements referred to in this Section 6.5, and (ii) issue or cause to be issued
the appropriate number of shares of Parent Common Stock pursuant to such
agreements, plans and programs, upon the exercise or maturation of rights
existing thereunder on the Merger Date or thereafter granted or awarded.
 
     SECTION 6.6  Further Assurances.  Subject to the terms and conditions
provided herein, each of the parties agrees to use its reasonable efforts to
take, or cause to be taken, all action and to do, or cause to be done, all
things necessary, proper or advisable under applicable law and regulation to
consummate and make effective the Mergers in accordance with the terms of this
Agreement and the Merger Agreements, subject, however, to the vote of
stockholders of Martin Marietta and Lockheed in accordance with Article II. In
case at any time after the Merger Date any further action is necessary or
desirable to carry out the purposes of this Agreement or the Merger Agreements,
the proper officers or directors of Martin Marietta and Lockheed shall take all
such necessary action.
 
     SECTION 6.7  No Solicitation.  Unless and until this Agreement shall have
been terminated by either party pursuant to Section 8.1, neither Martin Marietta
nor Lockheed nor any of their respective officers,
 
                                      I-17
<PAGE>   140
 
directors or agents shall directly or indirectly, encourage, solicit or initiate
discussions or negotiations with, or engage in negotiations or discussions with,
or provide any nonpublic information to, any corporation, partnership, person or
other entity or group (other than to Martin Marietta or Lockheed or an affiliate
or an associate of either Martin Marietta or Lockheed) concerning any merger,
sale of substantial assets, sale of shares of capital stock or similar
transactions involving Martin Marietta or Lockheed or any of their respective
Subsidiaries or divisions, unless its Board of Directors, upon written advice of
counsel, has determined that it is in the best interests of such Company's
stockholders to do so. In the event Martin Marietta or Lockheed shall receive
any proposal concerning any such transaction, such party shall promptly advise
the other as to such proposal and as to any discussions conducted in connection
therewith.
 
     SECTION 6.8  Public Announcements.  Martin Marietta and Lockheed will
consult with each other before issuing any press release relating to this
Agreement or the transactions contemplated herein and shall not issue any such
press release prior to such consultation, except as may be required by law or by
obligations pursuant to any listing agreement with any national securities
exchange.
 
     SECTION 6.9  Agreements with Respect to Martin Marietta Common Stock and
Lockheed Common Stock.  (a) Martin Marietta agrees that it will, and will use
its reasonable efforts to the end that its Subsidiaries will, (i) not tender
into any tender or exchange offer or sell, transfer or otherwise dispose of any
shares of the voting capital stock of Lockheed ("Lockheed Voting Stock") which
they own, (ii) vote all shares of Lockheed Voting Stock owned by them in favor
of the transactions contemplated by this Agreement and (iii) vote all shares of

assets, issuance of securities in exchange for cash or securities or other
property, liquidation or dissolution) involving Lockheed other than the
transactions contemplated by this Agreement.
 
     (b) Lockheed agrees that it will, and will use its reasonable efforts to

offer or sell, transfer or otherwise dispose of any shares of the voting capital
stock of Martin Marietta ("Martin Marietta Voting Stock") which they own, (ii)
vote all shares of Martin Marietta Voting Stock owned by them in favor of the
transactions contemplated by this Agreement and (iii) vote all shares of Martin
Marietta Voting Stock owned by them against any merger, consolidation, business
combination or other extraordinary corporate transaction (including without
limitation any reclassification of securities, recapitalization, sale, lease,
exchange or other disposition of all or substantially all of its respective
assets, issuance of securities in exchange for cash or securities or other
property, liquidation or dissolution) involving Martin Marietta other than the
transactions contemplated by this Agreement.
 
     SECTION 6.10  Indemnification and Insurance.  For a period of six years
after the Merger Date, Parent shall cause to be maintained in effect (a) the
current provisions regarding indemnification of officers and directors contained
in the charter and bylaws of Martin Marietta and the certificate of
incorporation and bylaws and officers and directors indemnification agreements
of Lockheed, and (b) the current policies of directors' and officers' liability
insurance and fiduciary liability insurance maintained by Martin Marietta and
Lockheed (provided that Parent may substitute therefor policies of at least the
same coverage and amounts containing terms and conditions which are, in the
aggregate, no less advantageous to the insured) with respect to claims arising
from facts or events which occurred on or before the Merger Date.
 
     SECTION 6.11  Accountants' "Comfort" Letters.  Martin Marietta and Lockheed
will each use reasonable efforts to cause to be delivered to each other letters
from their respective independent accountants, dated a date within two business
days before the date of the Registration Statement, in form and substance
reasonably satisfactory to the recipient and customary in scope and substance
for comfort letters delivered by independent accountants in connection with
registration statements on Form S-4.
 
     SECTION 6.12  Additional Reports.  Martin Marietta and Lockheed shall each
furnish to the other copies of any reports of the type referred to in Sections
4.4 and 5.4 which it files with the SEC on or after the date hereof, and Martin
Marietta or Lockheed, as the case may be, represents and warrants that as of the
respective dates thereof, such reports will not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statement therein, in light of the
 
                                      I-18
<PAGE>   141
 
circumstances under which they were made, not misleading. Any unaudited
consolidated interim financial statements included in such reports (including
any related notes and schedules) will fairly present the financial position of
Martin Marietta and its consolidated Subsidiaries or Lockheed and its
consolidated Subsidiaries, as the case may be, as of the dates thereof and the
results of operations and changes in financial position or other information
included therein for the periods or as of the date then ended (subject, where
appropriate, to normal year-end accrual adjustments), in each case in accordance
with past practice and GAAP consistently applied during the periods involved
(except as otherwise disclosed in the notes thereto).

termination of this Agreement pay to the other party an amount equal to such
other party's actual costs and expenses incurred in connection herewith,
provided that such reimbursement shall not exceed $15 million.
 
     SECTION 8.4 Amendment or Supplement.  At any time before or after approval

                           AUTHORIZED SHARES OF STOCK
 
     The total number of shares of stock of all classes which the Corporation
has authority to issue is 820,000,000 shares, divided into 20,000,000 shares of
Series A Preferred Stock, $1.00 par value per share, 50,000,000 shares of Series
Preferred Stock, $1.00 par value per share, and 750,000,000 shares of Common
Stock, $1.00 par value per share. The aggregate par value of all sharers of all
classes is $820,000,000.00.
 
     A description of each class with the preferences, conversion and other
rights, voting powers, restrictions, limitations as to dividends, qualifications
and terms and conditions of redemption of each class, is as follows:
 
A.  Series A Preferred Stock
 
     SECTION 1.  Designation, Amount and Rank.  The class of Preferred Stock
shall be designated "Series A Preferred Stock" and the authorized number of
shares constituting such class shall be 20,000,000. The Series A Preferred Stock
shall rank on a parity as to dividends and as to distribution of assets upon
liquidation, dissolution or winding up with any other class of Preferred Stock
which the Corporation may in the future issue and which by its terms is not
stated to rank junior to the Series A Preferred Stock and the Series A Preferred
Stock shall rank senior, as to dividends and to distribution of assets upon
liquidation, dissolution or winding up to all other classes or series of stock
of the Corporation which are currently outstanding or which the Corporation may
in the future issue.
 
     SECTION 2.  Dividends.  (a) The holders of outstanding shares of Series A
Preferred Stock will be entitled to receive, subject to the rights of holders of
any class of Preferred Stock which the Corporation may in the future issue which
ranks on a parity with the Series A Preferred Stock in respect of dividends, and
when, as and if declared by the Board of Directors out of funds legally
available therefor, cumulative preferential cash dividends at the per share rate
of $.75 for each of the quarters ending on the last day of March, June,
September and December of each year and no more, payable in arrears on each
succeeding April 1, July 1, October 1 and January 1, respectively (each such
date being hereinafter referred to as a "Preferred Dividend Payment Date")
commencing on that Preferred Dividend Payment Date which next follows the
issuance of such shares. Dividends shall (i) commence to accrue (whether or not
declared and whether or not funds are
 
                                      I-A-2
<PAGE>   148
 
legally available for payment) and shall be cumulative on the Series A Preferred
Stock from and after the last dividend payment date with respect to the Series A
Preferred Stock of Martin Marietta Corporation provided that all dividends have
been paid through such last dividend payment date and (ii) shall compound
quarterly, to the extent they are unpaid, at the rate of 6% per annum computed
on the basis of a 360-day year of twelve 30-day months. If any Preferred
Dividend Payment Date shall not be a Business Day, then the Preferred Dividend
Payment Date shall be on the next succeeding Business Day. Each such dividend
will be payable to holders of record as they appear on the stock books of the
Corporation on the record dates, not less than 10 nor more than 50 days
preceding the payment dates thereof, as shall be fixed by the Board of
Directors. As used herein, the term "Business Day" shall mean any day other than
a Saturday, Sunday, or a day on which banking institutions in the State of New
York are authorized or obligated by law or executive order to close or a day
which is or is declared a national or New York State holiday.
 
     (b) Holders of the shares of Series A Preferred Stock shall not be entitled
to any dividends on such shares, whether payable in cash, property or stock, in
excess of full cumulative dividends, as herein provided.
 
     (c) (i) So long as any share of Series A Preferred Stock shall remain
outstanding, no dividend or distribution whatsoever shall be declared or paid
upon or set apart for any class of stock or series thereof ranking junior to the
Series A Preferred Stock in payment of dividends nor shall any shares of any
class of stock or series thereof ranking junior to or on a parity with the
Series A Preferred Stock in payment of dividends be redeemed or purchased by the
Corporation or any subsidiary thereof nor shall any moneys be paid to or made
available for a sinking fund for redemption or purchase of any shares of any
class of stock or series thereof ranking junior to or on a parity with the
Series A Preferred Stock in payment of dividends, unless, in each such instance,
full dividends on all outstanding shares of Series A Preferred Stock for all
past dividend periods shall have been paid at the rate fixed therefor, the
dividends on all outstanding shares of Series A Preferred Stock for the then
current quarterly dividend period shall have been paid or declared and
sufficient funds set aside for payment thereof and all redemption payments with
respect to the Series A Preferred Stock which the Corporation shall have become
obligated to make shall have been made. Notwithstanding the immediately
preceding sentence, the Corporation shall be permitted to purchase or acquire
any preferred or common stock purchase rights of the Corporation ("Rights")
distributed pursuant to any rights agreements to which it may be a party (the
"Rights Agreement").
 
     (ii) No dividend shall be paid upon or declared or set apart for any share
of Series A Preferred Stock for any dividend period unless at the same time (a)
a like proportionate dividend for the same dividend period shall be paid upon or
declared or set apart for all shares of Series A Preferred Stock then
outstanding and entitled to receive such dividend and (b) there shall have been
paid upon or declared or set aside for all shares of any other class of stock or
series thereof, if any, then outstanding and ranking on a parity with the Series
A Preferred Stock in payment of dividends, for the same dividend period of the
Series A Preferred Stock, dividends ratably in proportion to the respective
dividend rates fixed for the Series A Preferred Stock and said parity stock. No
dividend shall be paid upon or declared or set apart for any shares of any other
class of stock or series thereof, if any, then outstanding and ranking on a
parity with Series A Preferred Stock in payment of dividends for any dividend
period, unless there shall have been paid upon or declared or set apart for all
shares then outstanding of Series A Preferred Stock, for the same dividend
period, dividends ratably in proportion to the respective dividend rates fixed
for the Series A Preferred Stock and said parity stock.
 
     SECTION 3.  Redemption.  (a) On or after the fifth anniversary of April 2,
1993 (the "Initial Issuance Date"), the Corporation, at its option, may redeem
any or all shares of Series A Preferred Stock, at a redemption price of $50 per
share, plus an amount equal to accrued and unpaid dividends thereon (whether or
not declared and whether or not funds are legally available for payment) to and
including the date of redemption (the "Redemption Price"), but only if the
Average Closing Price (as defined in Section 4(e)(vii) below) of the Common
Stock (calculated as of the record date fixed in accordance with Section 3(c)
for notifying holders of such redemption) equals or exceeds the applicable
percentage of the

preceded such record date:

</TABLE>
 
     Immediately prior to authorizing or making any such redemption with respect
to the Series A Preferred Stock, the Corporation, by resolution of its Board of
Directors, shall, to the extent of any funds legally available therefor, declare
a dividend on the Series A Preferred Stock payable on the redemption date in an
amount equal to any accrued and unpaid dividends on the Series A Preferred Stock
as of such date and, if the Corporation does not have sufficient funds legally
available therefor to declare and pay all dividends accrued at the time of such
redemption, then (i) the dividend shall be paid pro rata as among the Series A
Preferred Stock and any other Preferred Stock ranking on a parity as to
dividends with the Series A Preferred Stock in accordance with Section 2(c)(ii),
and (ii) an amount equal to any remaining accrued and unpaid dividends shall be
added to the redemption price of the Series A Preferred Stock.
 
     (b) If less than all the outstanding shares of Series A Preferred Stock are
to be redeemed, the shares to be redeemed shall be selected pro rata (subject to
rounding to avoid fractional shares) as nearly as practicable or by lot, or by
such other method as the Board of Directors may determine to be equitable.
 
     (c) Notice of any redemption shall be given by first class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the date fixed
for redemption to the holders of record of the shares of Series A Preferred
Stock to be redeemed at their respective addresses appearing on the stock books
of the Corporation. The Board of Directors of the Corporation shall fix a record
date for determining holders of record who are entitled to receive notice of any
redemption, not more than 10 days prior to the mailing of such notice. Notice so
mailed shall be conclusively presumed to have been duly given whether or not
actually received. Such notice shall state: (i) the date fixed for redemption;
(ii) the Redemption Price; (iii) whether the Redemption Price will be paid in
cash or, pursuant to Section 3(d) below, in Common Stock; (iv) that the holder
has the right to convert such shares into Common Stock until the close of
business on the second Business Day immediately preceding the related redemption
date, together with a statement of the then effective Conversion Price and the
place where certificates for such shares may be surrendered for conversion; (v)
the number of shares of Series A Preferred Stock to be redeemed and if less than
all the shares held by such holder are to be redeemed, the number of such shares
to be so redeemed from such holder; (vi) the place where certificates for such
shares are to be surrendered for payment of the Redemption Price; (vii) that
after the close of business on such date fixed for redemption the shares to be
redeemed shall not accrue dividends; and (viii) if the Redemption Price will be
paid in Common Stock, that the holder has the right to cause a Backstop
Registration of such Common Stock as described below. Upon surrender in
accordance with the aforesaid notice of the certificate for any shares of Series
A Preferred Stock so redeemed (duly endorsed or accompanied by appropriate
instruments of transfer, if so required by the Corporation in such notice), the
holders of record of such shares shall be entitled to receive the Redemption
Price, without interest. In case fewer than all the shares represented by any
such certificate are redeemed, a new certificate shall be issued representing
the unredeemed shares without cost to the holder thereof.
 
     (d) At the option of the Corporation, if notice of redemption is mailed as
aforesaid, and if prior to the date fixed for redemption funds or shares of
Common Stock sufficient to pay in full the Redemption Price are deposited in
trust, for the account of the holders of the shares to be redeemed, with a bank
or trust company named in such notice doing business in the Borough of
Manhattan, The City of New York, State of New York and having capital surplus
and undivided profits of at least $500 million (which bank or trust company also
may be the transfer agent and/or paying agent for the Series A Preferred Stock),
notwithstanding the fact that
 
                                      I-A-4
<PAGE>   150
 
any certificate(s) for shares called for redemption shall not have been
surrendered for cancellation, on and after such date of deposit the shares
represented thereby so called for redemption shall be deemed to be no longer
outstanding, and all rights of the holders of such shares as stockholders of the
Corporation shall cease, except the right of the holders thereof to convert such
shares in accordance with the provisions of Section 4 at any time prior to the
close of business on the second Business Day immediately preceding the related
redemption date and the right of the holders thereof to receive out of the funds
or shares of Common Stock so deposited in trust the Redemption Price, without
interest, upon surrender of the certificate(s) representing such shares. Any
funds or shares of Common Stock so deposited with such bank or trust company in
respect of shares of Series A Preferred Stock converted before the close of
business on the second Business Day immediately preceding the related redemption
date shall be returned to the Corporation upon such conversion. Any funds or
shares of Common Stock so deposited with such bank or trust company which shall
remain unclaimed by the holders of shares called for redemption at the end of
two years after the related redemption date shall be repaid to the Corporation,
on demand, and thereafter the holder of any such shares shall look only to the
Corporation for the payment, without interest thereon, of the Redemption Price.
 
     (e) (i) In lieu of paying the Redemption Price in cash, the Corporation
may, at its sole option, pay such Redemption Price in shares of Common Stock.
 
     (ii) The number of shares of Common Stock issuable in lieu of a cash
payment of the Redemption Price shall be the number of fully paid and
nonassessable shares (calculated to the nearest 1/100th of a share) of Common
Stock (which shares of Common Stock shall consist of authorized but unissued
shares) as shall have an aggregate Specified Value (as defined below) as of the
redemption date equal to the aggregate liquidation preference of the shares of
Series A Preferred Stock being redeemed. The shares to be redeemed shall be
selected pro rata from each holder; provided that, if the number of shares of
Series A Preferred Stock held by a holder which are subject to redemption as
aforesaid is not a whole number, the number of shares of Series A Preferred
Stock held by such holder to be redeemed as aforesaid shall be rounded upward to
the nearest whole number. The shares of Common Stock issuable on any redemption
to be paid in Common Stock will be delivered to the Corporation for the account
of such holders. By their acceptance of shares of Series A Preferred Stock, each
holder thereof shall be deemed (i) to have accepted the appointment of the
Corporation to act as such referred to below and (ii) to have appointed the
Corporation as its attorney-in-fact for purposes of making any endorsements on
certificates for shares of Common Stock received by such holder upon redemption
of shares of Series A Preferred Stock to the extent any such endorsement is
necessary or appropriate for purposes of effecting the sale of such shares of
Common Stock in a Backstop Registration, as described below. No fractional
shares of Common Stock will be issued upon redemption. A holder of shares of
Series A Preferred Stock who would otherwise be entitled to receive such a
fractional share shall, in lieu thereof, receive cash in an amount equal to the
same fraction of the Specified Value.
 
     (iii) For purposes hereof, "Specified Value" means the Average Closing
Price (as defined in Section 4(e)(vii)) per share of Common Stock as of the
applicable redemption date.
 
     (iv) Before any holder of shares of Series A Preferred Stock shall receive
certificates for shares of Common Stock in respect of the redemption of shares
of Series A Preferred Stock (or cash representing fractional share settlements
in respect thereof) such holder shall surrender the certificate or certificates
of shares of Series A Preferred Stock duly endorsed if required by the
Corporation, at the office of the Corporation and, if certificates for shares of
Common Stock are to be received by such holder, shall state in writing the name
or names and the denominations in which such holder wishes the certificate or
certificates for the Common Stock to be issued. The Corporation will, as soon as
practicable after receipt thereof, issue and deliver to such holder, or such
holder's designee or designees, a certificate or certificates for the number of
shares of Common Stock to which such holder shall be entitled as aforesaid,
together with a certificate or certificates representing any shares of Series A
Preferred Stock which are not to be redeemed, but which shall have constituted
part of the shares of Series A Preferred Stock represented by the certificate or
certificates so surrendered.
 
     (v) Each redemption of shares of Series A Preferred Stock paid in Common
Stock shall be deemed to have been made as of the close of business on the
applicable redemption date, so that the rights of the holder
 
                                      I-A-5
<PAGE>   151
 
of such shares of Series A Preferred Stock shall, to the extent of such
redemption, cease at such time and the person or persons entitled to receive
shares of the Common Stock upon redemption of such shares (including the person
or persons to whom any shares of Common Stock shall have been sold pursuant to a
Backstop Registration (as defined in Section 3(f)) shall be treated for all
purposes as having become the record holder or holders of the Common Stock at
such time, provided, however, that in the event a dividend, distribution,
subdivision, combination, reclassification, merger or similar event is declared
or occurs with respect to the shares of Common Stock, and the record date for
any such action is on or after the close of business on the record date for such
redemption, but prior to the close of business on the date of such redemption,
then the person or persons entitled to receive shares of the Common Stock upon
redemption of shares of Series A Preferred Stock (including the person or
persons to whom any shares of Common Stock shall have been sold pursuant to a
Backstop Registration) shall be treated for purposes of such action as having
become the record holder or holders of the Common Stock at the close of business
on the Trading Day (as defined in Section 4(e)(vii)) next preceding the record
date of such redemption. From and after the redemption, dividends on the shares
of Series A Preferred Stock redeemed with shares of Common Stock as a result of
such redemption shall cease to accrue, and said shares of Series A Preferred
Stock shall no longer be deemed to be outstanding.
 
     (vi) The Corporation will pay any and all taxes that may be payable in
respect of the issuance or delivery of shares of Common Stock upon redemption of
shares of Series A Preferred Stock pursuant hereto. The Corporation shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the delivery of shares of Common Stock pursuant to a
Backstop Registration registered in a name other than the name (x) in which such
shares of Series A Preferred Stock were formerly registered or (y) of any
underwriter participating in such Backstop Registration, and no such issue or
delivery shall be made unless and until the person requesting such issue or
delivery has paid to the Corporation the amount of any such tax, or has
established, to the satisfaction of the Corporation, that such tax has been
paid.
 
     (f) (i) Within 15 days of its receipt of notice pursuant to Section 3(c)
above of a redemption payable in shares of Common Stock, each holder of Series A
Preferred Stock shall have the right to elect not to retain such Common Stock
and to request a backstop registration (a "Backstop Registration") of the shares
of Common Stock received in the redemption by delivering to the Corporation a
written request specifying the amount of Common Stock that the holder proposes
not to retain and to sell pursuant to the Backstop Registration. A holder's
failure to timely deliver such notice shall be deemed to be an election by the
holder thereof to retain such Common Stock.
 
     (ii) The Corporation shall use its best efforts to cause such shares to be
registered under the Securities Act of 1933, as amended (the "Securities Act")
as soon as reasonably practicable so as to permit the sale thereof promptly. In
connection therewith, the Corporation shall prepare, and within 120 days of the
receipt of the request file, on Form S-3 if permitted or otherwise on the
appropriate form, a registration statement under the Securities Act to effect
such registration. Each holder requesting a Backstop Registration shall thereby
be deemed to agree to provide all such information and materials and to take all
such action as may be reasonably required in order to permit the Corporation to
comply with all applicable requirements of the Securities Act and the Securities
and Exchange Commission (the "Commission") and to obtain any desired
acceleration of the effective date of such registration statement. If the
offering to be registered is to be underwritten, the managing underwriter shall
be selected by the Corporation, and the Corporation and each requesting holder
shall enter into an underwriting agreement containing customary terms and
conditions. For purposes hereof the Common Stock required to be registered is
referred to herein as the "Subject Stock." The Corporation shall not be required
to include Subject Stock of any requesting holder therein if the requesting
holder does not agree to offer its stock by or through the underwriters selected
by the Corporation for the registration of the shares of Subject Stock and
execute an underwriting agreement in customary form. If a requesting holder has
been permitted to participate in a proposed offering pursuant to this Section
3(f), the Corporation thereafter may determine in its sole discretion either not
to file a registration statement, or otherwise not to consummate such offering,
in whole or in part, without any liability hereunder, except as provided herein.
 
     (iii) In connection with any Backstop Registration of shares of Subject
Stock registered pursuant hereto, the Corporation shall (A) furnish to the
requesting holders such number of copies of any prospectus
 
                                      I-A-6
<PAGE>   152
 
(including preliminary and summary prospectuses) and conformed copies of the
registration statement (including amendments or supplements thereto and, in each
case, all exhibits) and such other documents as they may reasonably request, but
only while the Corporation shall cause the registration statement to remain
current; (B)(1) use its best efforts to register or qualify the Subject Stock
covered by such registration statement under such blue sky or other state
securities laws for offer and sale and (2) keep such registration or
qualification in effect for so long as the registration statement remains in
effect; (C) use its best efforts to cause all shares of Subject Stock covered by
such registration statement to be registered with or approved by such other
federal or state government agencies or authorities as may be necessary in the
opinion of counsel to the Corporation to enable the requesting holders to
consummate the disposition of such shares of Subject Stock; (D) notify the
requesting holders any time when a prospectus relating thereto is required to be
delivered under the Securities Act upon discovery that, or upon the happening of
any event as a result of which, the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, in the light of the circumstances
under which they were made, and at the request of the requesting holders
promptly prepare and furnish to them a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that, as
thereafter delivered to the purchasers of such securities, such prospectus shall
not include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statement therein
not misleading, in the light of the circumstances under which they were made;
(E) otherwise use its best efforts to comply with all applicable rules and
regulations of the Commission; (F) use its best efforts to list the Subject
Stock covered by such registration statement on the New York Stock Exchange or
on any other securities exchange on which Subject Stock is then listed; and (G)
before filing any registration statement or any amendment or supplement thereto,
and as far in advance as is reasonably practicable, furnish to the requesting
holders copies of such documents. In connection with any offering of Subject
Stock registered pursuant to this Section 3(f), the Corporation shall (x)
furnish to the underwriter unlegended certificates representing ownership of the
Common Stock being sold in such denominations as requested and (y) instruct any
transfer agent and registrar of the Subject Stock to release any stop transfer
orders with respect to such Subject Stock. Upon any registration becoming
effective pursuant to this Section 3(f), the Corporation shall use its best
efforts to keep such registration statement current for a period of 60 days (or
90 days, if the Corporation is eligible to use a Form S3, or successor form) or
such shorter period as shall be necessary to effect the distribution of the
Subject Stock.
 
     (iv) By requesting Backstop Registration, each requesting holder shall be
deemed to agree that upon receipt of any notice from the Corporation of the
happening of any event of the kind described in subdivision (iii)(D) of this
Section 3(f), it will forthwith discontinue its disposition of Subject Stock
pursuant to the registration statement relating to such Subject Stock until its
receipt of the copies of the supplemented or amended prospectus contemplated by
subdivision (iii)(D) of this Section 3(f) and, if so directed by the
Corporation, will deliver to the Corporation all copies then in its possession
of the prospectus relating to such Subject Stock current at the time of receipt
of such notice.
 
     (v) The Corporation shall pay all agent fees and commissions and
underwriting discounts and commissions related to shares of Subject Stock being
sold by the requesting holders, the fees and disbursements of one counsel for
the requesting holders which shall be selected by a majority in interest of the
requesting holders and all other fees and expenses in connection with any
registration statement hereunder, including, without limitation, all
registration and filing fees, all printing costs, all fees and expenses of
complying with securities or blue sky laws and fees and disbursements of the
Corporation's counsel and accountants.
 
     (vi) In the case of any offering registered pursuant hereto, the
Corporation agrees to indemnify and hold the requesting holders, each
underwriter of the Subject Stock under such registration and each person who
controls any of the foregoing within the meaning of Section 15 of the Securities
Act, and any officer, employee or partner of the foregoing, harmless against any
and all losses, claims, damages, or liabilities (including reasonable legal fees
and other reasonable expenses incurred in the investigation and defense thereof)
to which they or any of them may become subject under the Securities Act or
otherwise (collectively "Losses"), insofar
 
                                      I-A-7
<PAGE>   153
 
as any such Losses shall arise out of or shall be based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
registration statement relating to the sale of such Subject Stock (as amended if
the Corporation shall have filed with the Commission any amendment thereof), or
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading or
(ii) any untrue statement or alleged untrue statement of a material fact
contained in the prospectus relating to the sale of such Subject Stock (as
amended or supplemented if the Corporation shall have filed with the Commission
any amendment thereof or supplement thereto), or the omission or alleged
omission to state therein a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading; provided, however, that the indemnification contained in this
Section 3(f)(vi) shall not apply to such Losses which shall arise out of or
shall be based upon any such untrue statement or alleged untrue statement, or
any such omission or alleged omission, which shall have been made in reliance
upon and in conformity with information furnished in writing to the Corporation
by a requesting holder or any such underwriter, as the case may be, specifically
for use in connection with the preparation of the registration statement or
prospectus contained in the registration statement or any such amendment thereof
or supplement thereto.
 
     In the case of each Backstop Registration pursuant to this Section 3(f),
each requesting holder and each underwriter participating therein shall agree,
substantially in the same manner and to the same extent as set forth in the
preceding paragraph, severally to indemnify and hold harmless the Corporation
and each person, if any, who controls the Corporation within the meaning of
Section 15 of the Securities Act, and the directors and officers of the
Corporation, with respect to any statement in or omission from such registration
statement or prospectus contained in such registration statement (as amended or
as supplemented, if amended or supplemented as aforesaid) if such statement or
omission shall have been made in reliance upon and in conformity with
information furnished in writing to the Corporation by a requesting holder or
such underwriter, as the case may be, specifically for use in connection with
the preparation of such registration statement or prospectus contained in such
registration statement or any such amendment thereof or supplement thereto.
 
     If the indemnification provided for in this Section 3(f) is unavailable to
an indemnified party or is insufficient to hold such indemnified party harmless
from any Losses in respect of which this Section 3(f) would otherwise apply by
its terms (other than by reason of exceptions provided herein), then each
applicable indemnifying party, in lieu of indemnifying such indemnified party,
shall have a joint and several obligation to contribute to the amount paid or
payable by such indemnified party as a result of such Losses, in such proportion
as is appropriate to reflect the relative benefits received by and fault of the
indemnifying party, on the one hand, and such indemnified party, on the other
hand, in connection with the offering to which such contribution relates as well
as any other relevant equitable considerations. The relative benefit shall be
determined by reference to, among other things, the amount of proceeds received
by each party from the offering to which such contribution relates. The relative
fault shall be determined by reference to, among other things, each party's
relative knowledge and access to information concerning the matter with respect
to which the claim was asserted, and the opportunity to correct and prevent any
statement or omission. The amount paid or payable by a party as a result of any
Losses shall be deemed to include any legal or other fees or expenses incurred
by such party in connection with any investigation or proceeding, to the extent
such party would have been indemnified for such expenses if the indemnification
provided for in this Section 3(f) was available to such party.
 
     (g) When the offering contemplated by Section 3(f) above has been
completed, the net proceeds thereof shall be distributed to the requesting
holders pro rata in respect of their interests in the Subject Stock. Any such
offering not consummated within six months of delivery of the notice to the
Corporation pursuant to Section 3(f)(i) shall be deemed to have been abandoned.
To the extent the net proceeds per share to each requesting holder from such
offering (treating the net proceeds as zero if such offering has been abandoned)
are less than the sum of the Redemption Price and the Interest Amount (as
defined below) in respect of such requesting holder's shares of Series A
Preferred Stock redeemed pursuant to this Section, the Corporation shall pay to
each requesting holder an amount in cash equal to the applicable difference.
"Interest Amount" means, with respect to the Redemption Price payable to any
holder for such holder's shares of Series A
 
                                      I-A-8
<PAGE>   154
 
Preferred Stock redeemed pursuant to this Section, interest on such Redemption
Price for each day, from the applicable redemption date to and including the
date of payment pursuant to this Section 3(g) at a rate per annum equal to the
rate per annum, as published by the Board of Governors of the Federal Reserve
System as reported by the U.S. Department of Treasury, for such day on U.S.
Treasury Bonds maturing on the date that is the tenth anniversary of such
redemption date (or if no U.S. Treasury Bonds mature on such date, then on the
date nearest to such date for which such a maturity exists).
 
     SECTION 4.  Conversion Rights.  The holders of shares of Series A Preferred
Stock shall have the right, at their option, to convert such shares into shares
of Common Stock on the following terms and conditions:
 
          (a) Each share of Series A Preferred Stock shall be convertible, at
     the option of the holder thereof, at any time after the date of issuance of
     such share and prior to the close of business of the Corporation on the
     second Business Day immediately preceding any date set for the redemption
     thereof (provided that consideration sufficient to redeem all shares to be
     redeemed on such date has been paid or made available for payment on or
     prior to such date), at the office of the Corporation or any transfer agent
     for the Series A Preferred Stock, into such number of fully paid and
     nonassessable shares of Common Stock as is determined by dividing $50 by
     the Conversion Price, determined as hereinafter provided, in effect at the
     time of conversion. The price at which shares of Common Stock shall be
     deliverable upon conversion (the "Conversion Price") shall initially be
     $34.5525 per share of Common Stock. The Conversion Price shall be subject
     to adjustment from time to time as hereinafter provided. No payment or
     adjustment shall be made on account of any dividend on the shares of Common
     Stock issued upon conversion of shares of Series A Preferred Stock if the
     record date for such dividend occurs prior to the date of such conversion.
     If any shares of Series A Preferred Stock shall be called for redemption,
     the right to convert the shares designated for redemption shall terminate
     after the close of business on the second Business Day immediately
     preceding the date fixed for redemption unless default is made in the
     payment of the Redemption Price. In the event of default in the payment of
     the Redemption Price, the right to convert the shares designated for
     redemption shall terminate at the close of business on the Business Day
     immediately preceding the date that such default is cured.
 
          (b) In order to convert shares of Series A Preferred Stock into Common
     Stock, the holder thereof shall surrender the certificates therefor, duly
     endorsed if the Corporation shall so require, or accompanied by appropriate
     instruments of transfer satisfactory to the Corporation, at the office of
     the transfer agent for the Series A Preferred Stock, or at such other
     office as may be designated by the Corporation, together with written
     notice that such holder irrevocably elects to convert such shares of Series
     A Preferred Stock. Such notice shall also state the name and address in
     which such holder wishes the certificate for the shares of Common Stock
     issuable upon conversion to be issued. As soon as practicable after receipt
     of the certificates representing the shares of Series A Preferred Stock to
     be converted and the notice of election to convert the same, the
     Corporation shall issue and deliver at said office a certificate for the
     number of whole shares of Common Stock issuable upon conversion of the
     shares of Series A Preferred Stock surrendered for conversion, together
     with a cash payment in lieu of any fraction of a share, as hereinafter
     provided, to the person entitled to receive the same. If more than one
     stock certificate for Series A Preferred Stock shall be surrendered for
     conversion at one time by the same holder, the number of full shares of
     Common Stock issuable upon conversion thereof shall be computed on the
     basis of the aggregate number of shares represented by all the certificates
     so surrendered. Shares of Series A Preferred Stock shall be deemed to have
     been converted immediately prior to the close of business on the date such
     shares are surrendered for conversion and notice of election to convert the
     same is received by the Corporation in accordance with the foregoing
     provision, and the person entitled to receive the Common Stock issuable
     upon such conversion shall be deemed for all purposes as the record holder
     of such Common Stock as of such date.
 
          (c) Dividends shall cease to accrue on shares of Series A Preferred
     Stock surrendered for conversion into Common Stock from and after the date
     of conversion; provided, however, that any accrued but unpaid dividends
     (whether or not declared and whether or not funds are legally available for
     payment) upon such shares to and including the conversion date shall be
     paid in cash upon such conversion or as soon thereafter as permitted by
     law.
 
                                      I-A-9
<PAGE>   155
 
          (d) No fractional shares of Common Stock shall be issued upon
     conversion of any shares of Series A Preferred Stock. If more than one
     share of Series A Preferred Stock is surrendered at one time by the same
     holder, the number of full shares issuable upon conversion thereof shall be
     computed on the basis of the aggregate number of shares so surrendered. If
     the conversion of any shares of Series A Preferred Stock results in a
     fractional share of Common Stock, the Corporation shall pay cash in lieu
     thereof in an amount equal to such fraction multiplied by the Average
     Closing Price, determined as provided in subsection (vii) of Section 4(e)
     below, on the date on which the shares of Series A Preferred Stock were
     duly surrendered for conversion, or if such date is not a Trading Date, on
     the next succeeding Trading Date.
 
          (e) The Conversion Price shall be adjusted from time to time as
     follows:
 
             (i) In case the Corporation shall pay or make a dividend or other
        distribution on shares of Common Stock or any other class of capital
        stock of the Corporation in Common Stock, the Conversion Price in effect
        at the opening of business on the date following the date fixed for the
        determination of stockholders entitled to receive such dividend or other
        distribution shall be reduced by multiplying such Conversion Price by a
        fraction of which the numerator shall be the number of shares of Common
        Stock outstanding at the close of business on the date fixed for such
        determination and the denominator shall be the sum of such number of
        shares and the total number of shares constituting such dividend or
        other distribution, such reduction to become effective immediately after
        the opening of business on the date following the date fixed for such
        determination. For purposes of this subsection, the number of shares of
        Common Stock at any time outstanding shall not include shares held in
        the treasury of the Corporation. The Corporation will not pay any
        dividend or make any distribution on shares of Common Stock held in the
        treasury of the Corporation.
 
             (ii) In case the Corporation shall issue shares of Common Stock or
        rights or warrants or other securities convertible into or exchangeable
        or exercisable for shares of Common Stock to any person (other than
        pursuant to (A) a dividend reinvestment plan, (B) the exercise of stock
        options granted with the approval of the Corporation's Board of
        Directors where the exercise price is not less than the Average Closing
        Price on the date the option was granted, (C) a restricted stock plan
        where the issuance is consistent with the past practices of Martin
        Marietta Corporation, Martin Marietta Technologies, Inc. or Lockheed
        Corporation, as determined by the Board of Directors, (D) a stock option
        or other stock incentive plan where the issuance is required in
        accordance with any obligation of Martin Marietta Corporation to provide
        benefits similar to those provided under certain plans of General
        Electric Company in effect prior to April 2, 1993 as determined by the
        Board of Directors, or (E) any option or other security of the
        Corporation issued in exchange for, or upon exercise or conversion of,
        any option or other security outstanding as of the Merger Date (as
        defined in the Agreement and Plan of Reorganization dated August 29,
        1994 among the Corporation, Martin Marietta Corporation and Lockheed
        Corporation) and theretofore issued by (X) Martin Marietta Corporation
        (provided that the exercise of any option or other security issued by
        Martin Marietta Corporation after April 2, 1993 with an exercise price
        less than the "Average Closing Price" (as defined in Section 4 of
        Article V of Martin Marietta Corporation's Charter) on the date of grant
        shall result in an adjustment under this clause (ii) to the same extent
        it would have resulted in an adjustment under Section 4 of Martin
        Marietta Corporation's Charter) or (Y) Lockheed Corporation), entitling
        such person to subscribe for or purchase shares of Common Stock at a
        price per share (or having a conversion, exercise or exchange price per
        share) in any case, less than the Average Closing Price per share
        (determined as provided in subsection (vii) below) of the Common Stock
        on the date of issuance (or in the case of any issuance of Common Stock,
        rights, warrants or such other securities to all holders of Common
        Stock, on the date fixed for the determination of the holders entitled
        to receive such Common Stock, rights, warrants or other securities), the
        Conversion Price in effect at the opening of business on the day
        following the date of such issuance or the date fixed for such
        determination, as the case may be, shall be reduced by multiplying such
        Conversion Price by a fraction of which the numerator shall be the
        number of shares of Common Stock
 
                                     I-A-10
<PAGE>   156
 
        outstanding at the close of business on the date of such issuance or the
        date fixed for such determination, as the case may be, plus the number
        of shares of Common Stock which the aggregate consideration receivable
        by the Corporation for the total number of shares of Common Stock so
        offered for subscription or purchase (or into or for which such rights,
        warrants or other securities are convertible, exchangeable or
        exercisable) would purchase at such Average Closing Price and the
        denominator shall be the number of shares of Common Stock outstanding at
        the close of business on the date of such issuance or the date fixed for
        such determination, as the case may be, plus the number of shares of
        Common Stock so offered for subscription or purchase (or into or for
        which such rights, warrants or other securities are convertible,
        exchangeable or exercisable), such reduction to become effective
        immediately after the opening of business on the date following the date
        of such issuance or the date fixed for such determination, as the case
        may be. For the purposes of this subsection (ii), the number of shares
        of Common Stock at any time outstanding shall not include shares held in
        the treasury of the Corporation. The Corporation will not issue any
        rights, warrants or other securities convertible into or exchangeable or
        exercisable for shares of Common Stock held in the treasury of the
        Corporation. If the Corporation adopts a shareholder rights plan (a
        "Rights Plan"), and after any Distribution Date (as defined in such
        Rights Plan) thereunder, holders converting shares of Series A Preferred
        Stock are not entitled to receive the Rights (as defined in such Rights
        Plan) which would otherwise be attributable (but for the date of
        conversion) to the shares of Common Stock received upon such conversion,
        then adjustment of the Conversion Price shall be made under this
        subsection (ii) as if the Rights were then being issued to holders of
        the Common Stock. If such an adjustment is made and the Rights are later
        redeemed, invalidated or terminated, then a corresponding reversing
        adjustment shall be made to the Conversion Price, on an equitable basis,
        to take account of such event. However, the Corporation may elect to
        provide that each share of Common Stock issuable upon conversion of the
        Series A Preferred Stock, whether or not issued after the Distribution
        Date for such Rights, will be accompanied by the Rights which would
        otherwise be attributable (but for the date of conversion) to such
        shares of Common Stock, in which event the preceding two sentences will
        not apply.
 
             (iii) In case outstanding shares of Common Stock shall be
        subdivided into a greater number of shares of Common Stock, the
        Conversion Price in effect at the opening of business on the day
        following the day upon which such subdivision becomes effective shall be
        proportionately reduced, and, conversely, in case outstanding shares of
        Common Stock shall be combined into a smaller number of shares of Common
        Stock, the Conversion Price in effect at the opening of business on the
        day following the day upon which such combination becomes effective
        shall be proportionately increased, such reduction or increase, as the
        case may be, to become effective immediately after the opening of
        business on the day following the day upon which such subdivision or
        combination becomes effective.
 
             (iv) In case the Corporation shall, by dividend or otherwise,
        distribute to all holders of its Common Stock or any other class of
        capital stock of the Corporation evidences of its indebtedness or assets
        (including securities, but excluding (x) any rights, warrants or other
        securities referred to in subsection (ii) above, (y) any regular
        quarterly dividend of the Corporation paid in cash out of the
        consolidated earnings or consolidated retained earnings of the
        Corporation in an amount not exceeding 125% of the average of the four
        regular quarterly dividends paid by the Corporation for the immediately
        preceding four quarters (including for this purpose dividends paid by
        Martin Marietta Corporation prior to the Merger Date), and (z) any
        dividend or distribution referred to in subsection (i) above), the
        Conversion Price shall be reduced so that the same shall equal the price
        determined by multiplying the Conversion Price in effect immediately
        prior to the close of business on the date fixed for the determination
        of stockholders entitled to receive such distribution by a fraction of
        which the numerator shall be the Average Closing Price (determined as
        provided in subsection (vii) below) of the Common Stock on the date
        fixed for such determination less the then fair market value (as
        reasonably determined by the Board of Directors, whose determination
        shall be conclusive and shall be described in a statement filed with the
        transfer agent for the Series A Preferred Stock) of the portion of the
        evidences of indebtedness or assets so distributed applicable to one
        share of
 
                                     I-A-11
<PAGE>   157
 
        Common Stock and the denominator shall be such Average Closing Price per
        share of the Common Stock, such adjustment to become effective
        immediately prior to the opening of business on the day following the
        date fixed for the determination of stockholders entitled to receive
        such distribution.
 
             (v) The reclassification of Common Stock into securities including
        securities other than Common Stock (other than any reclassification upon
        a consolidation or merger to which Section 4(g) below applies) shall be
        deemed to involve (A) a distribution of such securities other than
        Common Stock to all holders of Common Stock (and the effective date of
        such reclassification shall be deemed to be "the date fixed for the
        determination of stockholders entitled to receive such distribution" and
        the "date fixed for such determination" within the meaning of subsection
        (iv) above), and (B) a subdivision or combination, as the case may be,
        of the number of shares of Common Stock outstanding immediately prior to
        such reclassification into the number of shares of Common Stock
        outstanding immediately thereafter (and the effective date of such
        reclassification shall be deemed to be "the day upon which such
        subdivision becomes effective" or "the day upon which such combination
        becomes effective" as the case may be, and "the day upon which such
        subdivision or combination becomes effective" within the meaning of
        subsection (iii) above).
 
             (vi) In case at any time the Corporation or any subsidiary thereof
        shall repurchase, by self tender offer or otherwise, any shares of
        Common Stock of the Corporation at a weighted average purchase price in
        excess of the Average Closing Price (as defined in subsection (vii)
        below) on the Business Day immediately prior to the earliest of the date
        of such repurchase, the commencement of an offer to repurchase or the
        public announcement of either (such date being referred to as the
        "Determination Date"), the Conversion Price in effect as of such
        Determination Date shall be reduced by multiplying such Conversion Price
        by a fraction, the numerator of which shall be (I) the product of (x)
        the number of shares of Common Stock outstanding on such Determination
        Date and (y) the Average Closing Price of the Common Stock on such
        Determination Date minus (II) the aggregate purchase price of such
        repurchase and the denominator of which shall be the product of (x) the
        number of shares of Common Stock outstanding on such Determination Date
        minus the number of shares of Common Stock repurchased by the Company or
        any subsidiary thereof in such repurchase and (y) the Average Closing
        Price of the Common Stock on such Determination Date. An adjustment made
        pursuant to this subsection (vi) shall become effective immediately
        after the effective date of such repurchase.
 
             (vii) For the purposes of any computation under these provisions of
        the Corporation's Charter, the Average Closing Price per share of Common
        Stock on any day shall be deemed to be the average of the closing prices
        for the Common Stock for the 20 consecutive Trading Days commencing 30
        Trading Days before the day in question, with each day's closing sale
        price being the reported last sale price regular way or, in case no such
        reported sale takes place on such day, the average of the reported
        closing bid and asked prices, in either case on the New York Stock
        Exchange or, if the Common Stock is no longer listed or admitted to
        trading on such Exchange, on the principal national securities exchange
        on which the Common Stock is listed or admitted to trading or, if not
        listed or admitted to trading on any national securities exchange, on
        the National Association of Securities Dealers Automated Quotations
        National Market System or, if the Common Stock is not listed or admitted
        to trading on any national securities exchange or quoted on such
        National Market System, the average of the closing bid and asked prices
        in the over-the-counter market as furnished by any New York Stock
        Exchange member firm selected from time to time by the Board of
        Directors for that purpose. As used herein, the term "Trading Day" shall
        mean a date on which the New York Stock Exchange (or any successor to
        such Exchange) is open for the transaction of business.
 
             (viii) No adjustment in the Conversion Price for the Series A
        Preferred Stock shall be required unless such adjustment would require
        an increase or decrease of at least 1% in such price; provided, however,
        that any adjustments which by reason of this subsection (viii) are not
        required to be made shall be carried forward and taken into account in
        any subsequent adjustment. All calculations under this Section shall be
        made to the nearest cent or to the nearest one-hundredth of a share, as
        the case may be.
 
                                     I-A-12
<PAGE>   158
 
          (f) Whenever the Conversion Price shall be adjusted as herein provided
     (i) the Corporation shall forthwith make available at the office of the
     transfer agent for the Series A Preferred Stock a statement describing in
     reasonable detail the adjustment, the facts requiring such adjustment and
     the method of calculation used; and (ii) the Corporation shall cause to be
     mailed by first class mail, postage prepaid, as soon as practicable to each
     holder of record of shares of Series A Preferred Stock a notice stating
     that the Conversion Price has been adjusted and setting forth the adjusted
     Conversion Price.
 
          (g) In the event that the Corporation shall be a party to any
     transaction constituting a recapitalization, reclassification,
     consolidation, merger, share exchange, or a sale, lease or conveyance of
     all or substantially all of its assets, the holder of each share of Series
     A Preferred Stock shall have the right, after such consolidation, merger,
     sale or exchange to convert such share into the number and kind of shares
     of stock or other securities, and the amount of cash or other property
     receivable upon such consolidation, merger, sale or exchange by a holder of
     the number of shares of Common Stock issuable upon conversion of such share
     of Series A Preferred Stock immediately prior to such consolidation,
     merger, sale or exchange. No provision shall be made for adjustments in the
     Conversion Price. The provisions of this Section 4(g) shall similarly apply
     to any such successive event.
 
          (h) The Corporation shall not be required to pay any taxes which may
     be payable in respect of any transfer involved in the issuance of shares of
     Common Stock in the name other than that in which the shares of Series A
     Preferred Stock so converted are registered, and the Corporation shall not
     be required to issue or deliver any such shares unless and until the person
     requesting such issuance in another name shall have paid to the Corporation
     the amount of any such taxes, or shall have established to the satisfaction
     of the Corporation that such taxes have been paid.
 
          (i) The Corporation may make such reductions in the Conversion Price,
     in addition to those required by subsections (i) through (vi) of Section
     4(e) above, as it considers to be advisable in order that any event treated
     for federal income tax purposes as a dividend of stock or stock rights
     shall not be taxable to the recipients.
 
          (j) Except as provided in this Section 4, the Corporation will not, by
     amendment of its Charter or through any reorganization, transfer of assets,
     consolidation, merger, dissolution, issue or sale of securities or any
     other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms to be observed or performed hereunder by
     the Corporation, but will at all times in good faith assist in the carrying
     out of all the provisions of this Section 4 and in the taking of all such
     action as may be necessary or appropriate in order to protect the
     conversion rights of the holders of the Series A Preferred Stock against
     impairment.
 
          (k) The Corporation shall at all times reserve and keep available out
     of its authorized but unissued Common Stock the full number of shares of
     Common Stock issuable upon the conversion of all shares of Series A
     Preferred Stock then outstanding.
 
          (l) In the event that:
 
             (i) the Corporation shall declare a dividend or any other
        distribution on its Common Stock (other than any regular quarterly
        dividend described in Section 4(e)(iv) above) payable otherwise than in
        cash out of consolidated earnings or consolidated retained earnings;
 
             (ii) the Corporation shall authorize the granting to the holders of
        its Common Stock of rights to subscribe for or purchase any shares of
        capital stock of any class or of any other rights;
 
             (iii) any capital reorganization of the Corporation,
        reclassification of the capital stock of the Corporation, consolidation
        or merger of the Corporation with or into another corporation, or sale,
        lease or conveyance of all or substantially all of the assets of the
        Corporation occurs;
 
             (iv) the voluntary or involuntary dissolution, liquidation or
        winding up of the Corporation occurs; or
 
                                     I-A-13
<PAGE>   159
 
             (v) any other event for which an adjustment would be required
        pursuant to subsections (i) through (vi) of Section 4(e) or pursuant to
        Section 4(g) occurs;
 
the Corporation shall cause to be mailed to the holders of record of Series A
Preferred Stock at least 20 days prior to the applicable date hereinafter
specified a notice stating (x) the date on which a record is to be taken for the
purpose of such dividend, distribution or rights or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such dividend, distribution or rights are to be determined or (y) the date on
which such reorganization, reclassification, consolidation, merger, sale, lease,
conveyance, dissolution, liquidation or winding up or other event specified in
subsections (i) through (v) of this Section 4(l) is expected to take place, and
the date, if any is to be fixed, as of which holders of Common Stock of record
shall be entitled to exchange their shares of Common Stock for securities or
other property deliverable upon such reorganization, reclassification,
consolidation, merger, sale, lease, conveyance, dissolution, liquidation or
winding up or other such event. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of such dividend,
distribution, reorganization, reclassification, consolidation, merger, sale,
lease, conveyance, dissolution, liquidation or winding up or other such event.
 
     SECTION 5.  Voting Rights.  (a) Except as otherwise provided by paragraphs
(b), (c), (d) and (e) of this Section 5 or as required by law, the holders of
shares of Series A Preferred Stock shall not be entitled to vote on any matter
on which the holders of any voting securities of the Corporation shall be
entitled to vote.
 
     (b) Upon a default with respect to the Corporation's senior bank facility
or any successor thereto or replacement thereof (as amended from time to time,
the "Senior Bank Facility") that is not substantially cured within six months
from the declaration thereof pursuant to the Senior Bank Facility (but without
regard to any waivers granted by the lenders under such Senior Bank Facility) (a
"Bank Debt Default"), the holders of the Series A Preferred Stock, voting as a
separate class, shall be entitled to elect the smallest number of directors of
the Corporation's Board of Directors that shall constitute no less than 25% of
the authorized number of directors of the Corporation's Board of Directors until
such right is terminated as provided herein. The voting rights provided by this
Section 5(b) shall terminate immediately upon the initial holder of all
outstanding shares of Series A Preferred Stock being no longer entitled to
designate any director pursuant to Section 3.02 of the Standstill Agreement
dated April 2, 1993 between the Corporation (as successor to Martin Marietta
Corporation pursuant to, and as such Standstill Agreement is modified by, the
Reconfiguration Agreement dated August , 1993 among the Corporation, Martin
Marietta Corporation and General Electric Company), as so amended, and the
holders of the Series A Preferred Stock, following such termination, shall have
only the voting rights provided by Sections 5(c), (d) and (e) below or as
otherwise required by law.
 
     (c) In the event that dividends payable on the Series A Preferred Stock
shall be in arrears for six quarters (whether or not consecutive) (a "Preferred
Dividend Default") and the holders of the Series A Preferred Stock are not then
represented on the Corporation's Board of Directors by directors elected as a
result of a Bank Debt Default, a majority in interest of the holders of Series A
Preferred Stock, voting separately as a class with holders of shares of any
other class of Preferred Stock upon which like voting rights have been conferred
and are exercisable, shall be entitled to elect two directors of the Corporation
until such right is terminated as provided herein.
 
     (d) (i) Upon the occurrence of a Bank Debt Default or a Preferred Dividend
Default, the Board of Directors of the Company shall promptly call a special
meeting of the holders of shares of Series A Preferred Stock (and, in the case
of a Preferred Dividend Default, any holders of shares of any other class of
Preferred Stock who are then entitled to participate in the election of such
directors) for the purpose of electing the directors provided by the foregoing
provisions; provided that, in lieu of holding such meeting, the holders of
record of Series A Preferred Stock (and, in the case of a Preferred Dividend
Default, the holders of any such other Preferred Stock) may, by action taken by
written consent as permitted by law and the Charter and Bylaws of the
Corporation, elect such directors. At elections for such directors, each holder
of Series A Preferred Stock shall be entitled to one vote for each share held.
Upon the vesting of voting rights in the holders of Series A Preferred Stock as
a result of a Preferred Dividend Default or a Bank Debt Default, the maximum
authorized number of members of the Board of Directors shall automatically be
increased by two (or such greater number as may be required in respect of a Bank
Debt Default). The two vacancies (or greater
 
                                     I-A-14
<PAGE>   160
 
number) so created shall be filled by vote of the holders of Series A Preferred
Stock (and, in the case of a Preferred Dividend Default, the holders of any such
other Preferred Stock). The right of the holders of Series A Preferred Stock,
voting separately as a class (except as aforesaid), to elect members of the
Board of Directors of the Corporation in the manner described above shall
continue until such time as any Bank Debt Default shall have ceased (other than
as a result of any waiver, amendment or accommodation granted by the lenders
under such Senior Bank Facility), or all dividends accumulated on Series A
Preferred Stock shall have been paid in full, as the case may be, at which time
such right shall terminate, except as required by law, subject to vesting in the
event of each and every subsequent Bank Debt Default and Preferred Dividend
Default.
 
     (ii) Upon any termination of the right of the holders of Series A Preferred
Stock (and, in the case of a Preferred Dividend Default, the holders of shares
of any other class of Preferred Stock who are then entitled to vote on the
election of directors) to vote as a class for directors as herein provided, the
term of office of all directors then in office elected by holders of Series A
Preferred Stock (or such other holders, as the case may be) voting as a class
(hereunder referred to as a "Preferred Stock Director") shall terminate
immediately. Any Preferred Stock Director may be removed by, and shall not be
removed otherwise than by, the vote of the holders of record of Series A
Preferred Stock (or, in the case of any Preferred Stock Director elected as a
result of a Preferred Dividend Default, the holders of Series A Preferred Stock
together with holders of any other Preferred Stock that participated in the
election of such Preferred Stock Director) voting as a separate class, at a
meeting called for such purpose or by written consent as permitted by law and
the Charter and Bylaws of the Corporation. If the office of any Preferred Stock
Director becomes vacant by reason of death, resignation, retirement,
disqualification, removal from office, or otherwise, the remaining Preferred
Stock Director or Directors may choose a successor who shall hold office for the
unexpired term in respect of which such vacancy occurred or, if none remains in
office, by vote of the holders of record of Series A Preferred Stock (or, in the
case of any Preferred Stock Director elected as a result of a Preferred Dividend
Default, the holders of Series A Preferred Stock together with holders of any
other Preferred Stock that participated in the election of such Preferred Stock
Director). Holders of Series A Preferred Stock shall not, as such stockholders,
be entitled to vote on the election or removal of directors other than Preferred
Stock Directors. Whenever the special voting powers vested in the holders of
Series A Preferred Stock as provided herein shall have expired, the number of
directors shall become such number as may be provided for in the Bylaws,
irrespective of any increase made pursuant to the provisions hereof.
 
     (iii) So long as any shares of the Series A Preferred Stock remain
outstanding, the consent of the holders of at least 66 2/3% of the shares of
Series A Preferred Stock then outstanding (voting separately as a class) given
in person or by proxy, at any special or annual meeting called for such purpose,
or by written consent as permitted by law and the Charter and Bylaws of the
Corporation, shall be necessary to amend, alter or repeal any of the provisions
of the Charter of the Corporation which would adversely affect any right,
preference, privilege or voting power of Series A Preferred Stock or of the
holders thereof; provided, however, that any such amendment, alteration or
repeal, that would authorize, create or issue any additional shares of Preferred
Stock or any other shares of stock (whether or not already authorized) ranking
on a parity with or junior to the Series A Preferred Stock as to dividends and
on the distribution of assets upon liquidation, dissolution or winding up, shall
be deemed not to materially and adversely affect such rights, preferences,
privileges or voting powers.
 
     (e) The holder of each share of Series A Preferred Stock shall be entitled
to vote together with the holders of shares of Common Stock and to cast the
number of votes equal to the number of shares of Common Stock into which such
shares of Series A Preferred Stock are then convertible in the event of any
merger, consolidation or business combination or share exchange involving the
Corporation or any sale, lease or conveyance of all or substantially all of the
assets of the Corporation upon which the holders of Common Stock shall be
entitled to vote, provided, however, that the holders of the Series A Preferred
Stock shall not be entitled to vote upon acquisitions which, within any 12-month
period, do not (i) involve greater than an aggregate of Twenty-Five Million
Dollars ($25,000,000) of transaction value (including assumed liabilities,
whether contingent or not) or (ii) adversely affect the economic or legal
position of the Series A Preferred Stock or its rights, preferences, privileges
or voting powers.
 
                                     I-A-15
<PAGE>   161
 
     (f) The foregoing voting provisions shall not apply if, at or prior to the
time when the act with respect to which such vote would otherwise be required
shall be effected, all outstanding shares of the Series A Preferred Stock shall
have been redeemed for cash or converted for Common Stock and funds, if any,
necessary for such redemption or conversion shall have been deposited in trust
to effect such redemption.
 
     SECTION 6.  Liquidation Rights.  (a) Subject to the rights of holders of
any class of Preferred Stock which the Corporation may in the future issue which
ranks on a parity with the Series A Preferred Stock upon any dissolution,
liquidation or winding up of the affairs of the Corporation, whether voluntary
or involuntary (collectively, a "Liquidation"), the holders of shares of Series
A Preferred Stock shall be entitled to receive out of the assets of the
Corporation available for distribution to stockholders, whether from capital,
surplus or earnings, before any distribution or payment is made to holders of
Common Stock of the Corporation or on any other class of stock of the
Corporation ranking junior as to assets distributable upon Liquidation to the
shares of Series A Preferred Stock upon a Liquidation, liquidating distributions
in the amount of $50 per share, plus the amount equal to all dividends accrued
and unpaid thereon (including dividends accumulated and unpaid) to the date of
Liquidation, and no more.
 
     (b) Written notice of any Liquidation, stating the payment date or dates
when and the place or places where the amounts distributable in such
circumstances shall be payable, shall be given by first class mail, postage
prepaid, not less than 30 days prior to any payment date stated therein, to the
holders of record of the Series A Preferred Stock at their respective addresses
as the same shall appear on the books of the Corporation or any transfer agent
for the Series A Preferred Stock.
 
     (c) Neither the merger or consolidation of the Corporation into or with any
other corporation, nor the merger or consolidation of any other corporation into
or with the Corporation, nor a sale, transfer or lease of all or any part of the
assets of the Corporation, shall, without further corporate action, be deemed to
be a liquidation, dissolution or winding up of the affairs of the Corporation
within the meaning of this Section 6.
 
     SECTION 7.  Tax Provisions.  (a) The Corporation will treat the Series A
Preferred Stock as equity (not debt) for all federal, state, local and other tax
purposes.
 
     (b) The Corporation will use its reasonable best efforts to ensure that it
has adequate earnings and profits, within the meaning of Section 312 of the
Internal Revenue Code of 1986, as amended (the "Code"), or any successor
provision, to ensure that all dividend distributions on the Series A Preferred
Stock and all distributions in redemption of the Series A Preferred Stock that
are treated as distributions with respect to stock under Section 302(d) of the
Code (or any successor provision) will be treated as dividends within the
meaning of Section 316 of the Code (or any successor provision); provided that
such reasonable best efforts shall not require the Corporation to incur any
material out-of-pocket costs unless such costs are reimbursed by the initial
holder of the Series A Preferred Stock.
 
B. Series Preferred Stock
 
     The Board of Directors of the Corporation shall have the power from time to
time (a) to classify or reclassify, in one or more series, any unissued shares
of Series Preferred Stock and (b) to reclassify any unissued shares of any
series of Series Preferred Stock, in the case of either (a) or (b) by setting or
changing the number of shares constituting such series and the designation,
preference, conversion or other rights, voting powers, restrictions, limitations
as to dividends, qualifications and terms and conditions of redemption of such
shares, and, in such event, the Corporation shall file for record with the State
Department of Assessments and Taxation of Maryland articles supplementary in
substance and form as prescribed by the GCL.
 
     Without limiting any of the foregoing, the Board of Directors shall be
entitled to increase or decrease (but not below the number of shares of such
series then outstanding) the number of shares of any series of Series Preferred
Stock subsequent to the issuance of shares of that series.
 
                                     I-A-16
<PAGE>   162
 
C. Common Stock
 
     Subject to the rights of holders of shares of Series A Preferred Stock and
any series of Series Preferred Stock established pursuant to Section B of this
Article VI, each share of Common Stock shall entitle the holder to one vote per
share on all matters upon which stockholders are entitled to vote, to receive
dividends and other distributions authorized by Board of Directors in accordance
with the GCL and to all rights of a stockholder pursuant thereto. The Common
Stock shall have no preferences or preemptive, conversion or exchange rights.
 
D. General
 
     In determining whether a distribution (other than upon voluntary or
involuntary liquidation), by dividend, redemption or other acquisition of shares
or otherwise, is permitted under the GCL, no effect shall be given to amounts
that would be needed, if the Corporation were to be dissolved at the time of the
distribution, to satisfy the preferential rights upon dissolution of
stockholders whose preferential rights upon dissolution are superior to those
receiving the distribution.
 
                                  ARTICLE VII
 
                         PROVISIONS DEFINING, LIMITING
                             AND REGULATING POWERS
 
     The following provisions are hereby adopted for the purposes of defining,
limiting and regulating the powers of the Corporation and the directors and
stockholders, subject, however, to any provisions, conditions and restrictions
hereafter authorized pursuant to Article VI hereof:
 
          SECTION 1.  The Board of Directors of the Corporation is empowered to
     authorize the issuance from time to time of shares of its stock of any
     class, whether now or hereafter authorized, and securities convertible into
     shares of its stock of any class, whether now or hereafter authorized, for
     such consideration as the Board of Directors may deem advisable, subject to
     such limitations and restrictions, if any, as may be set forth in the
     Bylaws of the Corporation.
 
          SECTION 2.  No holders of shares of stock of the Corporation of any
     class shall have any preemptive or other right to subscribe for or purchase
     any part of any new or additional issue of stock of any class or of
     securities convertible into stock of any class, whether now or hereafter
     authorized, and whether issued for money, for a consideration other than
     money or by way of dividend.
 
          SECTION 3.  The Board of Directors shall have the power, from time to
     time, to determine whether any, and if any, what part, of the surplus of
     the Corporation shall be declared in dividends and paid to the
     stockholders, and to direct and determine the use and disposition of any
     such surplus. The Board of Directors may in its discretion use and apply
     any of such surplus in purchasing or acquiring any of the shares of the
     stock of the Corporation, or any of its bonds or other evidences of
     indebtedness, to such extent and in such manner and upon such lawful terms
     as the Board of Directors shall deem expedient.
 
          SECTION 4.  The Corporation reserves the right to adopt, repeal,
     rescind, alter or amend in any respect any provision contained in this
     Charter, including but not restricted to, any amendments changing the terms
     of any class of its stock by classification, reclassification or otherwise,
     and all rights conferred on stockholders herein are granted subject to this
     reservation.
 
          SECTION 5.  Notwithstanding any provision of law requiring any action
     to be taken or authorized by the affirmative vote of the holders of a
     designated proportion of the shares of stock of the Corporation, or to be
     otherwise taken or authorized by vote of the stockholders, such action
     shall be effective and valid, except as otherwise required by provisions of
     the Charter, if taken or authorized by the affirmative vote, at a meeting,
     of a majority of all votes entitled to be cast on the matter.

applicable and the other applicable provisions of the Charter related to the

     of outstanding shares of Voting Stock of the Corporation that caused the

          Clause 2.  The following conditions are satisfied:
 
             (a) The aggregate amount of the cash and fair market value of the

        acquiring any of its holdings of the Corporation's Voting Stock; and
 
             (b) A proxy statement complying with the requirements of the
        Securities Exchange Act of 1934, as amended, shall have been mailed to
        all stockholders of the Corporation for the purpose of soliciting
        stockholder approval of the Business Combination. The proxy statement
        shall contain at the front thereof, in a prominent place, the position
        of the Continuing Directors as to the advisability (or inadvisability)
        of the Business Combination and, if deemed advisable by a majority of
        the Continuing Directors, the opinion of an investment banking firm
        selected by the Continuing Directors as to the fairness of the terms of

        subsidiaries (in a single transaction or series of related transactions)
        of all or a Substantial Part of the assets of a Related Person;
 
             (d) the issuance or transfer of any equity securities of the
        Corporation or any of its subsidiaries by the Corporation or such
        subsidiary (in a single transaction or a series of related transactions)

     defined in Rule 12b-2 of the General Rules and Regulations under the
     Securities Exchange Act of 1934 as in effect at the Merger Date
     (collectively and as so in effect, the "Exchange Act")), which on or after
     the Merger Date became and then are "Beneficial Owners" (as defined in Rule
     13d-3 of the Exchange Act) in the aggregate of 10% or more of the
     outstanding shares of any class or series of Voting Stock of the
     Corporation, and any Affiliate or Associate of any such individual,

     to year end.
 
          Clause 4.  For the purposes of Clause 2(a) of Section 1 of this

          Clause 5.  The term "Subsidiary" shall mean any corporation of which a
     majority of the Voting Stock thereof entitled to vote generally in the
     election of directors is owned, directly or indirectly, by the Corporation
     (or another corporation, if so indicated).
 
          Clause 6.  The term "Voting Stock" shall mean all outstanding shares
     of capital stock of the Corporation or another corporation entitled to vote
     generally in the election of directors, and each reference to a proportion
     of shares of Voting Stock shall refer to such proportion of the votes
     entitled to be cast by such shares.
 
          Clause 7.  The term "Continuing Director" shall mean a director who
     either:
 
             (a) was a member of the Board of Directors of the Corporation
        immediately prior to the time that the Related Person involved in a

     Related Person under the foregoing definition of Related Person, if the
     price paid by such Related Person for such shares is not determinable by
     the Continuing Directors, the price so paid shall be deemed to be the
     higher of:
 
             (a) the price paid upon the acquisition thereof by the Affiliate,
        Associate, or other person; or
 
             (b) the market price of the shares in question at the time when the

          Clause 9.  The terms "Highest Per Share Price" and "Highest Equivalent
     Price" as used in this Article XIII shall mean the following. If there is
     only one class of Voting Stock of the Corporation issued and outstanding,
     the Highest Per Share Price shall mean the highest price that can be
     determined to have been paid at any time on or after the Merger Date by the
     Related Person for any share or shares of that class of Voting Stock. If
     there is more than one class of Voting Stock of the Corporation issued and
     outstanding, the Highest Equivalent Price shall mean, with respect to each
     class and series of Voting Stock of the Corporation, the amount determined
     by two-thirds of the Continuing Directors, on whatever basis they believe
     is appropriate, to be the highest per share price equivalent to the highest
     price that can be determined to have been paid at any time by the Related
     Person for any share or shares of any class or series of Voting Stock of
     the Corporation. In determining the Highest Per Share Price and Highest
     Equivalent Price, all purchases after the Merger Date by the Related Person
     shall be taken into account regardless of whether the shares were purchased
     before or after the Related Person became a Related Person. Also, the
     Highest Per Share Price and the Highest Equivalent Price shall include any
     brokerage commissions, transfer taxes, and soliciting dealers' fees paid by
     the Related Person with respect to the shares of Voting Stock of the
     Corporation acquired by the Related Person. In the case of any Business
     Combination with a Related Person, the Highest Equivalent Price for each
     class and series of the Voting Stock of the Corporation shall be determined
     by the Continuing Directors.
 
     SECTION 3.  Any amendment, change, or repeal of this Article XIII, or any
other amendment of this Charter which will have the effect of modifying or
permitting circumvention of this Article XIII, shall require the favorable vote,
at a meeting of the stockholders of the Corporation, of the holders of at least
(i) 80% of the then outstanding shares of the Voting Stock of the Corporation
and (ii) 67% of the outstanding shares of Voting Stock of the Corporation held
by stockholders other than a Related Person; provided, however, that this
Section 3 shall not apply to and such vote shall not be required for any such
amendment, change, or repeal recommended to stockholders by the affirmative vote
of not less than two-thirds of the Continuing Directors and such amendment,
change, or repeal so recommended shall require only the vote, if any, required
under the applicable provision of the Charter. For the purposes of this Section
3 only, if at the time when any such amendment, change, or repeal is under
consideration there is no proposed Business Combination (in which event, the
definition of Continuing Director in Clause 7 of Section 2 of this Article XIII
would be inapplicable), the "Continuing Directors" shall be deemed to be those
persons who are members of the Board of Directors of the Corporation at the
Merger Date, plus those persons who are Continuing Directors under Clause 7(b)
of Section 2 of this Article XIII.

                                       OF
 
                          LOCKHEED MARTIN CORPORATION
 
                                   ARTICLE I
 
                                  STOCKHOLDERS
 
     SECTION 1.01.  Annual Meetings.  The Corporation shall hold an annual
meeting of stockholders for the election of directors and the transaction of any
business within the powers of the Corporation on such date during the month of
April in each year as shall be determined by the Board of Directors, except that
the 1995 annual meeting of stockholders shall be held on February 6, 1995.
Subject to Article I, Section 1.11 of these Bylaws, any business of the
Corporation may be transacted at such annual meeting. Failure to hold an annual
meeting at the designated time shall not, however, invalidate the corporate
existence or affect otherwise valid corporate acts.
 
     SECTION 1.02.  Special Meetings.  At any time in the interval between
annual meetings, special meetings of the stockholders may be called by the
Chairman of the Board, President, or by the Board of Directors or by the
Executive Committee by vote at a meeting or in writing with or without a
meeting. Special meetings of stockholders shall also be called by the Secretary
of the Corporation on the written request of stockholders entitled to cast at
least 25% of all the votes entitled to be cast at the meeting.
 
     SECTION 1.03.  Place of Meetings.  All meetings of stockholders shall be
held at such place within the United States as may be designated in the notice
of meeting.
 
     SECTION 1.04.  Notice of Meetings.  Not less than thirty (30) days nor more
than ninety (90) days before the date of every stockholders' meeting, the
Secretary shall give to each stockholder entitled to vote at such meeting and
each other stockholder entitled to notice of the meeting, written or printed
notice stating the time and place of the meeting and, in the case of a special
meeting, the purpose or purposes for which the meeting is called, either by mail
or by presenting it to him or her personally or by leaving it at his or her
residence or usual place of business. If mailed, such notice shall be deemed to
be given when deposited in the United States mail addressed to the stockholder
at his or her post office address as it appears on the records of the
Corporation, with postage thereon prepaid. Notwithstanding the foregoing
provision for notice, a waiver of notice in writing, signed by the person or
persons entitled to such notice and filed with the records of the meeting,
whether before or after the holding thereof, or actual attendance at the meeting
in person or by proxy, shall be deemed equivalent to the giving of such notice
to such persons. Any meeting of stockholders, annual or special, may adjourn
from time to time without further notice to a date not more than one hundred
twenty (120) days after the original record date at the same or some other
place.
 
     SECTION 1.05.  Conduct of Meetings.  Each meeting of stockholders shall be
conducted in accordance with such rules and procedures as the Board of Directors
may determine subject to the requirements of applicable law and the Charter. The
Chairman of the Board, or in his or her absence the President, or in their
absence the person designated in writing by the Chairman of the Board, or if no
person is so designated, then a person designated by the Board of Directors,
shall preside as chairman of the meeting; if no person is so designated, then
the meeting shall choose a chairman by a majority of all votes cast at a meeting
at which a quorum is present. The Secretary or in the absence of the Secretary a
person designated by the chairman of the meeting shall act as secretary of the
meeting.
 
     SECTION 1.06.  Quorum.  At any meeting of stockholders, the presence in
person or by proxy of stockholders entitled to cast a majority of the votes
thereat shall constitute a quorum; but this section shall not affect any
requirement under statute or under the Charter of the Corporation for the vote
necessary for the adoption of any measure. In the absence of a quorum, the
stockholders present in person or by proxy, by majority vote and without further
notice, may adjourn the meeting from time to time to a date not more than 120
days after the original record date until a quorum shall attend. At any such
adjourned meeting at which a quorum shall be present, any business may be
transacted which might have been transacted at the meeting as originally
notified.

<PAGE>   174
 
     SECTION 1.07.  Votes Required.  Unless applicable law or the Charter of the
Corporation provides otherwise, at a meeting of stockholders, the vote of a
majority of the votes entitled to be cast at a meeting, duly called and at which
a quorum is present, shall be required to take or authorize action upon any
matter which may properly come before the meeting. Unless the Charter provides
for a greater or lesser number of votes per share or limits or denies voting
rights, each outstanding share of stock, regardless of class, shall be entitled
to one vote on each matter submitted to a vote at a meeting of stockholders; but
no share shall be entitled to any vote if any installment payable thereon is
overdue and unpaid.
 
     SECTION 1.08.  Proxies.  A stockholder may vote the shares owned of record
by him or her either in person or by proxy executed in writing by the
stockholder or by his or her duly authorized attorney-in-fact. No proxy shall be
valid after eleven (11) months from its date, unless otherwise provided in the
proxy. Every proxy shall be in writing, subscribed by the stockholder or his or
her duly authorized attorney, and dated, but need not be sealed, witnessed or
acknowledged.
 
     SECTION 1.09.  List of Stockholders.  At each meeting of stockholders, a
true and complete list of all stockholders entitled to vote at such meeting,
stating the number and class of shares held by each, shall be furnished by the
Secretary.
 
     SECTION 1.10.  Inspectors of Election.  In advance of any meeting of
stockholders, the Board of Directors may appoint Inspectors of Election to act
at such meeting or at any adjournment or adjournments thereof. If such
Inspectors are not so appointed or fail or refuse to act, the chairman of any
such meeting, upon the demand of stockholders present in person or by proxy
entitled to cast 25% of all the votes entitled to be cast at the meeting, shall
make such appointments.
 
     If there are three (3) or more Inspectors of Election, the decision, act or
certificate of a majority shall be effective in all respects as the decision,
act or certificate of all. The Inspectors of Election shall determine the number
of shares outstanding, the voting power of each, the shares represented at the
meeting, the existence of a quorum, the authenticity, validity and effect of
proxies; shall receive votes, ballots, assents or consents, hear and determine
all challenges and questions in any way arising in connection with the vote,
count and tabulate all votes, assents and consents, and determine the result;
and do such acts as may be proper to conduct the election and the vote with
fairness to all stockholders. On request, the Inspectors shall make a report in
writing of any challenge, question or matter determined by them, and shall make
and execute a certificate of any fact found by them.
 
     No such Inspector need be a stockholder of the Corporation.
 
     SECTION 1.11.  Director Nominations and Stockholder Business.
 
     (a) Nominations and Stockholder Business at Annual Meetings of
Stockholders.  Nominations of persons for election to the Board of Directors of
the Corporation and the proposal of business to be considered by the
stockholders may be made at an annual meeting of stockholders (i) pursuant to
the Corporation's notice of meeting, (ii) by or at the direction of the Board of
Directors or (iii) by any stockholder of the Corporation who was a stockholder
of record at the time of giving of notice provided for in this Section 1.11(a),
who is entitled to vote at the meeting and who complied with the notice
procedures set forth in this Section 1.11(a).
 
     For nominations or other business to be properly brought before an annual
meeting by a stockholder pursuant to clause (iii) of paragraph (a) of this
Section 1.11, the stockholder must have given timely notice thereof in writing
to the Secretary of the Corporation. To be timely, a stockholder's notice shall
be delivered to the Secretary at the principal executive offices of the
Corporation not less than sixty (60) days nor more than ninety (90) days prior
to the first anniversary of the preceding year's annual meeting; provided,
however, that in the event that the date of the annual meeting is advanced by
more than thirty (30) days or delayed by more than sixty (60) days from such
anniversary date, notice by the stockholder to be timely must be so delivered
not earlier than the 90th day prior to such annual meeting and not later than
the close of business on the later of the 60th day prior to such annual meeting
or the 10th day following the day on which public announcement of the date of
such meeting is first made. Such stockholder's notice shall set forth (i) as to
each person whom the stockholder proposes to nominate for election or reelection
as a director, (A) the name, age, business
 
                                      I-B-5
<PAGE>   175
 
address and residence address of such person, (B) the class and number of shares
of capital stock of the Corporation that are beneficially owned by such person,
and (C) all other information relating to such person that is required to be
disclosed in solicitations of proxies for election of directors, or is otherwise
required, in each case pursuant to Regulation 14A (or any successor provision)
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")
(including such person's written consent to being named in the proxy statement
as a nominee and to serving as a director if elected); (ii) as to any other
business that the stockholder proposes to bring before the meeting, a brief
description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting and any material interest in
such business of such stockholder and the beneficial owner, if any, on whose
behalf the proposal is made; and (iii) as to the stockholder giving the notice
and the beneficial owner, if any, on whose behalf the nomination or proposal is
made, the name and address of such stockholder, as they appear on the
Corporation's books, and of such beneficial owner and the class and number of
shares of stock of the Corporation which are owned beneficially and of record by
such stockholder and such beneficial owner.
 
     Notwithstanding anything in this paragraph (a) of this Section 1.11 to the
contrary, in the event that Section 2.02 of these Bylaws is amended, altered or
repealed so as to increase or decrease the maximum or minimum number of
directors and there is no public announcement of such action at least seventy
(70) days prior to the first anniversary of the preceding year's annual meeting,
a stockholder's notice required by this Section 1.11(a) shall also be considered
timely, but only with respect to nominees for director, if it shall be delivered
to the Secretary at the principal executive offices of the Corporation not later
than the close of business on the 10th day following the day on which such
public announcement is first made by the Corporation.
 
     (b) Director Nominations and Stockholder Business at Special Meetings of
Stockholders.  Only such business shall be conducted at a special meeting of
stockholders as shall have been brought before the meeting pursuant to the
Corporation's notice of meeting. Nominations of persons for election to the
Board of Directors may be made at a special meeting of stockholders at which
directors are to be elected pursuant to the Corporation's notice of meeting (i)
by or at the direction of the Board of Directors or (ii) provided that the Board
of Directors has determined that directors shall be elected at such special
meeting, by any stockholder of the Corporation who is a stockholder of record at
the time of giving of notice provided for in this Section 1.11, who is entitled
to vote at the meeting and who complied with the notice procedures set forth in
this Section 1.11. In the event the Corporation calls a special meeting of
stockholders for the purpose of electing one or more directors to the Board, any
such stockholder may nominate a person or persons (as the case may be) for
election to such position(s) as specified in the Corporation's notice of
meeting, if the stockholder's notice required by paragraph (a) of this Section
1.11 shall be delivered to the Secretary at the principal executive offices of
the Corporation not earlier than the 90th day prior to such special meeting and
not later than the close of business on the later of the 60th day prior to such
special meeting or the 10th day following the day on which public announcement
is first made of the date of the special meeting and of the nominees proposed by
the Board of Directors to be elected at such meeting.
 
     (c) General.  Only such persons who are nominated in accordance with the
procedures set forth in this Section 1.11 shall be eligible to serve as
directors and only such business shall be conducted at a meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 1.11. The presiding officer of the meeting shall have
the power and duty to determine whether a nomination or any business proposed to
be brought before the meeting was made in accordance with the procedures set
forth in this Section 1.11 and, if any proposed nomination or business is not in
compliance with this Section 1.11, to declare that such defective nomination or
proposal be disregarded.
 
     For purposes of this Section 1.11, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or comparable news service or in a document publicly filed by the
Corporation with the Securities and Exchange Commission pursuant to Sections 13,
14 or 15(d) of the Exchange Act.
 
     Notwithstanding the foregoing provisions of this Section 1.11, a
stockholder shall also comply with all applicable requirements of state law and
of the Exchange Act and the rules and regulations thereunder with
 
                                      I-B-6
<PAGE>   176
 
respect to the matters set forth in this Section 1.11. Nothing in this Section
1.11 shall be deemed to affect any rights of stockholders to request inclusion
of proposals in the Corporation's proxy statement pursuant to Rule 14a-8 (or any
successor provision) under the Exchange Act.
 
                                   ARTICLE II
 
                               BOARD OF DIRECTORS
 
     SECTION 2.01.  Powers.  The business and affairs of the Corporation shall
be managed under the direction of its Board of Directors. The Board of Directors

     giving rise to the proceeding; and
 
             (1) Was committed in bad faith; or

Members of the Board:
 
     We understand that Lockheed Martin Corporation ("Parent"), Lockheed
Corporation ("Lockheed") and Martin Marietta Corporation ("Martin Marietta")
have entered into an Agreement and Plan of Reorganization, dated as of August
29, 1994, as amended as of February 7, 1995, and the related Plan and Agreement
of Merger (collectively, the "Reorganization Agreement"), which provide, among
other things, for Lockheed and Martin Marietta to cause Parent to form two
wholly owned subsidiaries named Pacific Sub, Inc. ("Pacific Sub") and Atlantic
Sub, Inc. ("Atlantic Sub") and for the merger of Pacific Sub into Lockheed and
the merger of Atlantic Sub into Martin Marietta (the "Combination"). Pursuant to
the Combination, (i) Lockheed will become a wholly owned subsidiary of Parent
and each issued and outstanding share of common stock, par value $1.00 per share
(the "Lockheed Common Stock") of Lockheed, other than shares of Lockheed Common
Stock held in treasury or owned by Martin Marietta or any subsidiary of Martin
Marietta, will be converted into the right to receive 1.630 (the "Lockheed
Exchange Ratio") shares of common stock, par value $1.00 per share (the "Parent
Common Stock") of Parent, and (ii) Martin Marietta will become a wholly owned
subsidiary of Parent and each issued and outstanding share of common stock, par
value $1.00 per share (the "Martin Marietta Common Stock") of Martin Marietta,
other than shares of Martin Marietta Common Stock owned by Lockheed or any
subsidiary of Lockheed, will be converted into the right to receive 1.000 share
of Parent Common Stock and each issued and outstanding share of Series A
Preferred Stock, par value $1.00 per share (the "Martin Marietta Preferred
Stock") of Martin Marietta other than shares of Martin Marietta Preferred Stock
owned by Lockheed or any affiliate of Lockheed, will be converted into and
become one share of Series A Preferred Stock, par value $1.00 per share, of
Parent. The terms and conditions of the Combination are more fully set forth in
the Reorganization Agreement.
 
     You have asked for our opinion as to whether the Lockheed Exchange Ratio
pursuant to the Reorganization Agreement is fair from a financial point of view
to the holders of shares of Lockheed Common Stock.
 
     For purposes of the opinion set forth herein, we have:
 
          (i) analyzed certain publicly available financial statements and other
     information of Lockheed and Martin Marietta, respectively;
 
          (ii) analyzed certain internal financial statements and other
     financial and operating data concerning Martin Marietta prepared by the
     management of Martin Marietta;
 
          (iii) analyzed certain financial projections prepared by the
     management of Martin Marietta;
 
          (iv) discussed the past and current operations and financial condition
     and the prospects of Martin Marietta with senior executives of Martin
     Marietta;

available estimates and judgments of the future financial performance of
Lockheed and Martin Marietta. We have not made any independent valuation or
appraisal of the assets or liabilities of Lockheed or Martin Marietta nor have
we been furnished with any such appraisals. We have assumed that the Combination
will be accounted for as a "pooling-of-interests" business combination in
accordance with U.S. Generally Accepted Accounting Principles and will be

Agreement. Our opinion is necessarily based on economic, market and other
conditions as in effect on, and the information made available to us as of, the
date hereof.
 
     We have acted as financial advisor to the Board of Directors of Lockheed in
connection with this transaction and will receive a fee for our services,
including a payment which is contingent upon consummation of the Combination. In
the past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financial advisory and financing services for Lockheed and Martin Marietta and
have received fees for the rendering of these services.
 
     It is understood that this letter is for the information of the Board of
Directors of Lockheed only and may not be used for any other purpose without our
prior written consent. We hereby consent, however, to the inclusion of this
opinion as an exhibit to any proxy or registration statement distributed in
connection with the Combination.

     Based on and subject to the foregoing, we are of the opinion on the date
hereof that the Lockheed Exchange Ratio pursuant to the Reorganization Agreement
is fair from a financial point of view to the holders of shares of Lockheed
Common Stock.

                                                                February 9, 1995
 
Board of Directors
Martin Marietta Corporation
6801 Rockledge Drive
Bethesda, MD 20817
 
Dear Sirs and Madam:
 
     We understand that Martin Marietta Corporation ("Martin Marietta") and
Lockheed Corporation ("Lockheed") are considering merging into subsidiaries of a
new corporation ("Lockheed Martin") in a transaction pursuant to which each
share of common stock of Martin Marietta would be converted into one common
share of Lockheed Martin, each share of Series A Preferred Stock of Martin
Marietta would be converted into one share of Lockheed Martin Series A Preferred
Stock with substantially similar terms, and each share of common stock of
Lockheed would be converted into 1.63 common shares of Lockheed Martin (the
"Transaction"). You have provided us with a copy of the proxy statement in
substantially the final form to be sent to the stockholders of Martin Marietta
(the "Joint Proxy Statement/Prospectus"), which includes the Reorganization
Agreement and the Merger Agreements with respect to the Transaction. We further
understand that the Transaction will be accounted for as a pooling of interests
as contemplated by the Joint Proxy Statement/Prospectus.
 
     You have asked us to render our opinion as to whether the Transaction is
fair, from a financial point of view, to the stockholders of Martin Marietta.
 
     In the course of our analyses for rendering this opinion, we have:
 
          1. reviewed the Joint Proxy Statement/Prospectus;
 
          2. reviewed Martin Marietta's and Lockheed's respective Annual Reports
     to Shareholders and Annual Reports on Form 10-K for the fiscal years ended
     December 1990 through 1993, and their respective Quarterly Reports on Form
     10-Q for the fiscal periods ended March, June and September 1994;
 
          3. reviewed certain operating and financial information, including
     projections, provided to us by Martin Marietta's and Lockheed's managements
     relating to their respective business prospects;
 
          4. met with certain members of Martin Marietta's and Lockheed's senior
     managements to discuss their operations, historical financial statements
     and future prospects and their views of the business, operational and
     strategic benefits, potential synergies and other implications of the
     Transaction;
 
          5. reviewed the pro forma financial impact of the Transaction on
     Martin Marietta;
 
          6. reviewed the historical stock prices and trading volumes of the
     common stock of Martin Marietta and of Lockheed;
 
          7. reviewed publicly available financial information and stock market
     performance data of other publicly-held companies which we deemed generally
     comparable to Martin Marietta and to Lockheed;
 
                                      III-1
<PAGE>   194
 
          8. reviewed the financial terms of certain other recent acquisitions
     of companies which we deemed generally comparable to Martin Marietta and to
     Lockheed; and
 
          9. conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In the course of our review, we have relied upon and assumed, without
independent verification, the accuracy and completeness of the financial and
other information provided to us by Martin Marietta and Lockheed, and we have
further relied upon the assurances of management of Martin Marietta and Lockheed
that they are unaware of any facts that would make the information provided to
us incomplete or misleading. In arriving at our opinion, we have not performed
or obtained any independent appraisal of the assets of Martin Marietta or
Lockheed nor have we been furnished with any such appraisals. Our opinion is
necessarily based on the economic, market, and other conditions as in effect on,
and the information made available to us as of the date hereof.
 
     We have acted as financial advisor to Martin Marietta in connection with
the Transaction and will receive a fee for such advisory services, including the
rendering of this opinion, payment of a significant portion of which is
contingent upon the consummation of the Transaction.
 
     In the ordinary course of our business, we may actively trade the equity
securities of Martin Marietta and Lockheed for our own account and for the
accounts of customers and accordingly, may, at any time, hold a long or short
position in such securities.
 
     It is understood that this letter is intended solely for the benefit and
use of the Board of Directors of Martin Marietta and is not to be used for any
other purpose without our prior written consent, which shall not be unreasonably
withheld.
 
     Based on and subject to the foregoing, it is our opinion that, as of the
date hereof, the Transaction is fair, from a financial point of view, to the
stockholders of Martin Marietta.
 
                                        Very truly yours,
 
                                        BEAR, STEARNS & CO. INC.

SECTION 3.  Eligibility.
 
     Any one or more Awards may be granted to any Employee who is designated by
the Committee to receive an Award, provided that no individual who beneficially
owns Stock possessing five percent (5%) or more of the combined voting power of
all classes of stock of the Corporation shall be eligible to participate in this
Plan.
 
SECTION 4.  Awards.
 
     (a) Type of Awards.  The Committee may grant any of the following types of
Awards, either singly, in tandem or in combination with other Awards:
 
          (1) Nonqualified Stock Options.  A Nonqualified Stock Option is an
     Award in the form of an option to purchase Stock that is not intended to
     comply with the requirements of Code Section 422. The exercise price of
     each Nonqualified Stock Option granted under this Plan shall be not less
     than the Fair Market Value of the Stock on the date that the Option is
     granted or, if the exercise price of an Option is reduced by amendment, the
     Fair Market Value of the Stock on the date of the amendment. All
     Nonqualified Stock Options granted at an exercise price not less than Fair
     Market Value on the date of grant shall be treated as Performance-Based
     Awards subject to the applicable restrictions of Section 4(b).
 
          (2) Incentive Stock Options.  An Incentive Stock Option is an Award in
     the form of an option to purchase Stock that is intended to comply with the
     requirements of Code Section 422 or any successor section of the Code. The
     exercise price of each Incentive Stock Option granted under this Plan shall
     be not less than the Fair Market Value of the Stock on the date the Option
     is granted or, if the exercise price of an Option is reduced by amendment,
     the Fair Market Value of the Stock on the date of the amendment. To the
     extent that the aggregate "fair market value" of Stock with respect to
     which one or more incentive stock options first become exercisable by a
     Participant in any calendar year exceeds $100,000, taking into account both
     Stock subject to Incentive Stock Options under this Plan and stock subject
     to incentive stock options under all other plans of the Corporation or of
     other entities referenced in Code Section 422(d)(1), the options shall be
     treated as Nonqualified Stock Options. For this purpose, the "fair market
     value" of the Stock subject to options shall be determined as of the date
     the Options were awarded. All Incentive Stock Options granted at an
     exercise price not less than Fair Market Value on the date of grant shall
     be treated as Performance-Based Awards subject to the applicable
     restrictions of Section 4(b).
 
          (3) Stock Appreciation Rights.  A Stock Appreciation Right is an Award
     in the form of a right to receive, upon surrender of the right, but without
     other payment, an amount based on appreciation in the value of Stock over a
     base price established in the Award, payable in cash, Stock or such other
     form or combination of forms of payout, at times and upon conditions (which
     may include a Change in Control), as may be approved by the Committee. The
     minimum base price of a Stock Appreciation Right granted under this Plan
     shall be not less than the lowest of the Fair Market Value of the
     underlying Stock on the date the Stock Appreciation Right is granted or, if
     the base price of a Stock Appreciation Right is reduced by amendment, the
     Fair Market Value of the Stock on the date of the amendment, or, in the
     case of a Stock Appreciation Right related to an Option (whether already
     outstanding or concurrently granted), the exercise price of the related
     Option. All Stock Appreciation Rights granted at a base price not less than
     Fair Market Value on the date of grant shall be treated as
     Performance-Based Awards subject to the applicable restrictions under
     Section 4(b).
 
          (4) Restricted Stock.  Restricted Stock is an Award of shares of Stock
     of the Corporation that are issued, but subject to restrictions on transfer
     and/or such other restrictions on incidents of ownership as the Committee
     may determine. Restricted Stock Awards to Executive Officers that are
     either granted or vest upon attainment of one or more of the Performance
     Goals shall only be granted as Performance-Based Awards under Section 4(b).

          (5) Other Share-Based Awards.  The Committee may from time to time
     grant Awards under this Plan that provide the Participants with Stock or
     the right to purchase Stock, or provide other incentive Awards (including,
     but not limited to phantom stock or units, performance stock or units,
     bonus stock, dividend equivalent units, or similar securities or rights)
     that have a value derived from the value of, or an exercise or conversion
     privilege at a price related to, or that are otherwise payable in shares of
     Stock. The Awards shall be in a form determined by the Committee, provided
     that the Awards shall not be inconsistent with the other express terms of
     this Plan. Awards under this Section 4(a)(5) to Executive Officers that are
     either granted or become vested, exercisable or payable based on attainment
     of one or more of the Performance Goals shall only be granted as
     Performance-Based Awards under Section 4(b).
 
          (6) Cash-Based Awards.  Cash-Based Awards are Awards that provide
     Participants with the opportunity to earn a cash payment based upon the
     level of performance of the Corporation relative to one or more Performance
     Goals established by the Committee for an award cycle of more than one but
     not more than five years. For each award cycle, the Committee shall
     determine the size of the Awards, the Performance Goals, the performance
     targets as to each of the Performance Goals, the level or levels of
     achievement necessary for award payments and the weighting of the
     Performance Goals, if more than one Performance Goal is applicable.
     Cash-Based Awards to Executive Officers that are either granted or become
     vested, exercisable or payable based on attainment of one or more
     Performance Goals shall only be granted as Performance-Based Awards under
     Section 4(b).
 
     (b) Special Performance-Based Awards.  Without limiting the generality of
the foregoing, any of the type of Awards listed in Section 4(a) may be granted
as awards that satisfy the requirements for "performance-based compensation"
within the meaning of Code Section 162(m) ("Performance-Based Awards"), the
grant, vesting, exercisability or payment of which depends on the degree of
achievement of the Performance Goals relative to preestablished targeted levels
for the Corporation on a consolidated basis. Notwithstanding anything contained
in this Section 4(b) to the contrary, any Option or Stock Appreciation Right
with an exercise price or a base price not less than Fair Market Value on the
date of grant shall be subject only to the requirements of clauses (1) and
(3)(A) below in order for such Awards to satisfy the requirements for
Performance-Based Awards under this Section 4(b) (with such Awards hereinafter
referred to as a "Qualifying Option" or a "Qualifying Stock Appreciation Right",
respectively). With the exception of any Qualifying Option or Qualifying Stock
Appreciation Right, an Award that is intended to satisfy the requirements of
this Section 4(b) shall be designated as a Performance-Based Award at the time
of grant.
 
          (1) Eligible Class.  The eligible class of persons for Awards under
     this Section 4(b) shall be all Employees.
 
          (2) Performance Goals.  The performance goals for any Awards under
     this Section 4(b) (other than Qualifying Options and Qualifying Stock
     Appreciation Rights) shall be, on an absolute or relative basis, one or
     more of the Performance Goals. The specific performance target(s) with
     respect to Performance Goal(s) must be established by the Committee in
     advance of the deadlines applicable under Code Section 162(m) and while the
     performance relating to the Performance Goal(s) remains substantially
     uncertain.
 
          (3) Individual Limits.
 
             (A) Share-Based Awards.  The maximum number of shares of Stock or
        Share Units that are issuable under Options, Stock Appreciation Rights,
        Restricted Stock or other Share-Based Awards (described under Section
        4(a)(5)) that are granted as Performance-Based Awards during any
        calendar year to any Participant shall not exceed 500,000, either
        individually or in the aggregate, subject to adjustment as provided in
        Section 7. Awards that are cancelled or repriced during the year shall
        be counted against this limit to the extent required by Code Section
        162(m).
 
             (B) Cash-Based Awards.  The aggregate amount of compensation to be
        paid to any Participant in respect of those Cash-Based Awards that are
        granted during any calendar year as Performance-Based Awards shall not
        exceed $3,000,000.
 
                                      IV-4
<PAGE>   201
 
          (4) Committee Certification.  Before any Performance-Based Award under
     this Section 4(b) (other than Qualifying Options and Qualifying Stock
     Appreciation Rights) is paid, the Committee must certify in writing (by
     resolution or otherwise) that the applicable Performance Goal(s) and any
     other material terms of the Performance-Based Award were satisfied;
     provided, however, that a Performance-Based Award may be paid without
     regard to the satisfaction of the applicable Performance Goal in the event
     of a Change in Control as provided in Section 7(b).
 
          (5) Terms and Conditions of Awards; Committee Discretion to Reduce
     Performance Awards.  The Committee shall have discretion to determine the
     conditions, restrictions or other limitations, in accordance with the terms
     of this Plan and Code Section 162(m), on the payment of individual
     Performance-Based Awards under this Section 4(b). To the extent set forth
     in an Award Agreement, the Committee may reserve the right to reduce the
     amount payable in accordance with any standards or on any other basis
     (including the Committee's discretion), as the Committee may impose.
 
          (6) Adjustments for Material Changes.  In the event of (i) a change in
     corporate capitalization, a corporate transaction or a complete or partial
     corporate liquidation, or (ii) any extraordinary gain or loss or other
     event that is treated for accounting purposes as an extraordinary item
     under generally accepted accounting principles, or (iii) any material
     change in accounting policies or practices affecting the Corporation and/or
     the Performance Goals or targets, then, to the extent any of the foregoing
     events (or a material effect thereof) was not anticipated at the time the
     targets were set, the Committee may make adjustments to the Performance
     Goals and/or targets, applied as of the date of the event, and based solely
     on objective criteria, so as to neutralize, in the Committee's judgment,
     the effect of the event on the applicable Performance-Based Award.
 
          (7) Interpretation.  Except as specifically provided in this Section
     4(b), the provisions of this Section 4(b) shall be interpreted and
     administered by the Committee in a manner consistent with the requirements
     for exemption of Performance-Based Awards granted to Executive Officers as
     "performance-based compensation" under Code Section 162(m) and regulations
     and other interpretations issued by the Internal Revenue Service
     thereunder.
 
     (c) Maximum Term of Awards.  No Award that contemplates exercise or
conversion may be exercised or converted to any extent, and no other Award that
defers vesting, shall remain outstanding and unexercised, unconverted or
unvested more than ten years after the date the Award was initially granted.
 
SECTION 5.  Shares of Stock and Share Units Available Under Plan.
 
     (a) Aggregate Share Limit.  The maximum number of shares of Stock that may
be issued pursuant to all Share-Based Awards (including Incentive Stock Options)
is 12,000,000, subject to adjustment as provided in this Section 5 or Section 7.
 
     (b) Aggregate Share Unit Limit.  The maximum number of Share Units that may
be paid pursuant to all Share-Based Awards is 12,000,000, subject to adjustment
as provided in this Section 5 or Section 7. Notwithstanding the foregoing, if a
Share-Based Award paid or payable in Units satisfies the requirements for an
exclusion from the definition of a derivative security under Rule 16a-1(c) that
does not require that the Award be made under a Rule 16b-3 plan, the Share Units
that may be paid under the Award shall not be counted against the Share Unit
limit of this Section 5(b).
 
     (c) Reissue of Shares and Share Units.  Any unexercised, unconverted or
undistributed portion of any expired, cancelled, terminated or forfeited Award,
or any alternative form of consideration under an Award that is not paid in
connection with the settlement of an Award or any portion of an Award, shall
again be available for Award under Section 5(a) or 5(b), as applicable, whether
or not the Participant has received benefits of ownership (such as dividends or
dividend equivalents or voting rights) during the period in which the
Participant's ownership was restricted or otherwise not vested. Shares of Stock
that are issued pursuant to Awards and subsequently reacquired by the
Corporation pursuant to the terms and conditions of the Awards shall be
available for reissuance under the Plan.
 
                                      IV-5
<PAGE>   202
 
     (d) Interpretive Issues.  Additional rules for determining the number of
shares of Stock or Share Units authorized under this Plan may be adopted by the
Committee, as it deems necessary or appropriate.
 
     (e) Treasury Shares; No Fractional Shares.  The Stock which may be issued
(which term includes Stock reissued or otherwise delivered) pursuant to an Award
under this Plan may be treasury or authorized but unissued Stock or Stock
acquired, subsequently or in anticipation of a transaction under this Plan, in
the open market or in privately negotiated transactions to satisfy the
requirements of this Plan. No fractional shares shall be issued but fractional
interests may be accumulated.
 
     (f) Consideration.  The Stock issued under this Plan may be issued (subject
to Section 10(d)) for any lawful form of consideration, the value of which
equals the par value of the Stock or such greater or lesser value as the
Committee, consistent with Sections 10(d) and 4(a)(1), (2) and (3), may require.
 
     (g) Purchase or Exercise Price; Withholding.  The exercise or purchase
price (if any) of the Stock issuable pursuant to any Award and any withholding
obligation under applicable tax laws shall be paid in cash or, subject to the
Committee's express authorization and the restrictions, conditions and
procedures as the Committee may impose, any one or combination of (i) cash, (ii)
the delivery of shares of Stock, (iii) a reduction in the amount of Stock or
other amounts otherwise issuable or payable pursuant to such Award, or (iv) the
delivery of a promissory note, or other obligation for the future payment in
money, the terms and conditions of which shall be determined (subject to Section
10(d)) by the Committee. In the case of a payment by the means described in
clause (ii) or (iii) above, the Stock to be so delivered or offset shall be
determined by reference to the Fair Market Value of the Stock on the date as of
which the payment or offset is made.
 
     (h) Cashless Exercise.  The Committee may permit the exercise of the Award
and payment of any applicable withholding tax in respect of an Award by delivery
of written notice, subject to the Corporation's receipt of a third party payment
in full in cash for the exercise price and the applicable withholding prior to
issuance of Stock, in the manner and subject to the procedures as may be
established by the Committee.
 
SECTION 6.  Award Agreements.
 
     Each Award under this Plan shall be evidenced by an Award Agreement in a
form approved by the Committee setting forth, in the case of Share-Based Awards,
the number of shares of Stock or Share Units, as applicable, subject to the
Award, and the price (if any) and term of the Award and, in the case of
Performance-Based Awards, the applicable Performance Goals. The Award Agreement
shall also set forth (or incorporate by reference) other material terms and
conditions applicable to the Award as determined by the Committee consistent
with the limitations of this Plan.
 
     (a) Incorporated Provisions.  Award Agreements shall be subject to the
terms of this Plan and shall be deemed to include the following terms, unless
the Committee in the Award Agreement otherwise (consistent with applicable legal
considerations) provides:
 
          (1) Non-assignability:  The Award shall not be assignable nor
     transferable, except by will or by the laws of descent and distribution,
     and during the lifetime of a Participant the Award shall be exercised only
     by such Participant or by his or her guardian or legal representative. The
     designation of a Beneficiary hereunder shall not constitute a transfer
     prohibited by the foregoing provisions.
 
          (2) Rights as Stockholder:  A Participant shall have no rights as a
     holder of Stock with respect to any unissued securities covered by an Award
     until the date the Participant becomes the holder of record of these
     securities. Except as provided in Section 7, no adjustment or other
     provision shall be made for dividends or other stockholder rights, except
     to the extent that the Award Agreement provides for dividend equivalents or
     similar economic benefits.
 
          (3) Withholding:  The Participant shall be responsible for payment of
     any taxes or similar charges required by law to be withheld from an Award
     or an amount paid in satisfaction of an Award and these obligations shall
     be paid by the Participant on or prior to the payment of the Award. In the
     case of an Award payable in cash, the withholding obligation shall be
     satisfied by withholding the applicable amount
 
                                      IV-6
<PAGE>   203
 
     and paying the net amount in cash to the Participant. In the case of an
     Award paid in shares of Stock, a Participant shall satisfy the withholding
     obligation as provided in Section 5(g).
 
          (4) Option Holding Period:  Subject to the authority of the Committee
     under Section 7, a minimum six-month period shall elapse between the date
     of initial grant of any Option and the sale of the underlying shares of
     Stock, and the Corporation may impose legend and other restrictions on the
     Stock issued on exercise of the Options to enforce this requirement.
 
     (b) Other Provisions.  Award Agreements may include other terms and
conditions as the Committee shall approve, including but not limited to the
following:
 
          (1) Termination of Employment:  A provision describing the treatment
     of an Award in the event of the retirement, disability, death or other
     termination of a Participant's employment with or services to the Company,
     including any provisions relating to the vesting, exercisability,
     forfeiture or cancellation of the Award in these circumstances, subject, in
     the case of Performance-Based Awards, to the requirements for
     "performance-based compensation" under Code Section 162(m).
 
          (2) Vesting; Effect of Termination; Change in Control:  Any other
     terms consistent with the terms of this Plan as are necessary and
     appropriate to effect the Award to the Participant, including but not
     limited to the vesting provisions, any requirements for continued
     employment, any other restrictions or conditions (including performance
     requirements) of the Award, and the method by which (consistent with
     Section 7) the restrictions or conditions lapse, and the effect on the
     Award of a Change in Control.
 
          (3) Replacement and Substitution:  Any provisions permitting or
     requiring the surrender of outstanding Awards or securities held by the
     Participant in whole or in part in order to exercise or realize rights
     under or as a condition precedent to other Awards, or in exchange for the
     grant of new or amended Awards under similar or different terms.
 
          (4) Reloading.  Any provisions for successive or replenished Awards,
     including but not limited to reload Options.
 
     (c) Contract Rights, Forms and Signatures.  Any obligation of the
Corporation to any Participant with respect to an Award shall be based solely
upon contractual obligations created by this Plan and an Award Agreement. No
Award shall be enforceable until the Award Agreement or a receipt has been
signed by the Participant and on behalf of the Corporation by an Executive
Officer (other than the recipient) or his or her delegate or, in the case of an
Award to an Insider, by the Participant and the Corporation, whose signature
shall be acknowledged by a member of the Committee. By executing the Award
Agreement or receipt, a Participant shall be deemed to have accepted and
consented to the terms of this Plan and any action taken in good faith under
this Plan by and within the discretion of the Committee, the Board of Directors
or their delegates. Unless the Award Agreement otherwise expressly provides,
there shall be no third party beneficiaries of the obligations of the
Corporation to the Participant under the Award Agreement.
 
SECTION 7.  Adjustments; Change in Control; Acquisitions.
 
     (a) Adjustments.  If there shall occur any recapitalization, stock split
(including a stock split in the form of a stock dividend), reverse stock split,
merger, combination, consolidation, or other reorganization or any extraordinary
dividend or other extraordinary distribution in respect of the Stock (whether in
the form of cash, Stock or other property), or any split-up, spin-off,
extraordinary redemption, or exchange of outstanding Stock, or there shall occur
any other similar corporate transaction or event in respect of the Stock, or a
sale of substantially all the assets of the Corporation as an entirety, then the
Committee shall, in the manner and to the extent, if any, as it deems
appropriate and equitable to the Participants and consistent with the terms of
this Plan, and taking into consideration the effect of the event on the holders
of the Stock:
 
          (1) proportionately adjust any or all of
 
             (A) the number and type of shares of Stock and Share Units which
        thereafter may be made the subject of Awards (including the specific
        maxima and numbers of shares of Stock or Share Units set forth elsewhere
        in this Plan),
 
                                      IV-7
<PAGE>   204
 
             (B) the number and type of shares of Stock, other property, Share
        Units or cash subject to any or all outstanding Awards,
 
             (C) the grant, purchase or exercise price, or conversion ratio of
        any or all outstanding Awards, or of the Stock, other property or Share
        Units underlying the Awards,
 
             (D) the securities, cash or other property deliverable upon
        exercise or conversion of any or all outstanding Awards,
 
             (E) subject to Section 4(b), the performance targets or standards
        appropriate to any outstanding Performance-Based Awards, or
 
             (F) any other terms as are affected by the event; or
 
          (2) subject to any applicable limitations in the case of a transaction
     to be accounted for as a pooling of interests under generally accepted
     accounting principles, provide for
 
             (A) an appropriate and proportionate cash settlement or
        distribution, or
 
             (B) the substitution or exchange of any or all outstanding Awards,
        or the cash, securities or property deliverable on exercise, conversion
        or vesting of the Awards;
 
Notwithstanding the foregoing, in the case of an Incentive Stock Option, no
adjustment shall be made which would cause this Plan to violate Section 424(a)
of the Code or any successor provisions thereto, without the written consent of
the Participant adversely affected thereby. The Committee may act prior to an
event described in this paragraph (a) (including at the time of an Award by
means of more specific provisions in the Award Agreement) if deemed necessary or
appropriate to permit the Participant to realize the benefits intended to be
conveyed by an Award in respect of the Stock in the case of an event described
in paragraph (a).
 
     (b) Change in Control.  The Committee may, in the Award Agreement, provide
for the effect of a Change in Control on an Award. Such provisions may include,
but are not limited to any one or more of the following with respect to any or
all Awards: (i) the specific consequences of a Change in Control on the Awards;
(ii) a reservation of the Committee's right to determine in its discretion at
any time that there shall be full acceleration or no acceleration of benefits
under the Awards; (iii) that only certain or limited benefits under the Awards
shall be accelerated; (iv) that the Awards shall be accelerated for a limited
time only; or (v) that acceleration of the Awards shall be subject to additional
conditions precedent (such as a termination of employment following a Change in
Control).
 
     In addition to any action required or authorized by the terms of an Award,
the Committee may take any other action it deems appropriate to ensure the
equitable treatment of Participants in the event of or in anticipation of a
Change in Control, including but not limited to any one or more of the following
with respect to any or all Awards: (i) the acceleration or extension of time
periods for purposes of exercising, vesting in, or realizing gain from, the
Awards; (ii) the waiver of conditions on the Awards that were imposed for the
benefit of the Corporation, (iii) provision for the cash settlement of the
Awards for their equivalent cash value, as determined by the Committee, as of
the date of the Change in Control; or (iv) such other modification or adjustment
to the Awards as the Committee deems appropriate to maintain and protect the
rights and interests of Participants upon or following the Change in Control.
The Committee also may accord any Participant a right to refuse any acceleration
of exercisability, vesting or benefits, whether pursuant to the Award Agreement
or otherwise, in such circumstances as the Committee may approve.
 
     Notwithstanding the foregoing provisions of this Section 7(b) or any
provision in an Award Agreement to the contrary, (i) in no event shall the
Committee be deemed to have discretion to accelerate or not accelerate or make
other changes in or to any or all Awards, in respect of a transaction, if such
action or inaction would be inconsistent with or would otherwise frustrate the
intended accounting for a proposed transaction as a pooling of interests under
generally accepted accounting principles; and (ii) if any Award to any Insider
is accelerated to a date that is less than six months after the date of the
Award, the Committee may prohibit a sale of the underlying Stock (other than a
sale by operation or law in exchange for or through conversion into
 
                                      IV-8
<PAGE>   205
 
other securities), and the Corporation may impose legend and other restrictions
on the Stock to enforce this prohibition.
 
     (c) Change in Control Definition.  For purposes of this Plan, a change of
control shall include and be deemed to occur upon the following events:
 
          (1) A tender offer or exchange offer is consummated for the ownership
     of securities of the Corporation representing 25% or more of the combined
     voting power of the Corporation's then outstanding voting securities
     entitled to vote in the election of directors of the Corporation.
 
          (2) The Corporation is merged, combined, consolidated, recapitalized
     or otherwise reorganized with one or more other entities that are not
     Subsidiaries and, as a result of the merger, combination, consolidation,
     recapitalization or other reorganization, less than 75% of the outstanding
     voting securities of the surviving or resulting corporation shall
     immediately after the event be owned in the aggregate by the stockholders
     of the Corporation (directly or indirectly), determined on the basis of
     record ownership as of the date of determination of holders entitled to
     vote on the action (or in the absence of a vote, the day immediately prior
     to the event).
 
          (3) Any person (as this term is used in Sections 3(a)(9) and 13(d)(3)
     of the Exchange Act, but excluding any person described in and satisfying
     the conditions of Rule 13d-1(b)(1) thereunder), becomes the beneficial
     owner (as defined in Rule 13d-3 under the Exchange Act), directly or
     indirectly, of securities of the Corporation representing 25% or more of
     the combined voting power of the Corporation's then outstanding securities
     entitled to vote in the election of directors of the Corporation.
 
          (4) At any time within any period of two years after a tender offer,
     merger, combination, consolidation, recapitalization, or other
     reorganization or a contested election, or any combination of these events,
     the "Incumbent Directors" shall cease to constitute at least a majority of
     the authorized number of members of the Board. For purposes hereof,
     "Incumbent Directors" shall mean the persons who were members of the Board
     immediately before the first of these events and the persons who were
     elected or nominated as their successors or pursuant to increases in the
     size of the Board by a vote of at least three-fourths of the Board members
     who were then Board members (or successors or additional members so elected
     or nominated).
 
          (5) The stockholders of the Corporation approve a plan of liquidation
     and dissolution or the sale or transfer of substantially all of the
     Corporation's business and/or assets as an entirety to an entity that is
     not a Subsidiary.
 
     (d) Business Acquisitions.  Awards may be granted under this Plan on the
terms and conditions as the Committee considers appropriate, which may differ
from those otherwise required by this Plan to the extent necessary to reflect a
substitution for or assumption of stock incentive awards held by employees of
other entities who become employees of the Corporation or a Subsidiary as the
result of a merger of the employing entity with, or the acquisition of the
property or stock of the employing entity by, the Corporation or a Subsidiary,
directly or indirectly.
 
SECTION 8.  Administration.
 
     (a) Committee Authority and Structure.  This Plan and all Awards granted
under this Plan shall be administered by the Compensation Committee of the Board
or such other committee of the Board as may be designated by the Board and
constituted so as to permit this Plan to comply with the disinterested
administration requirements of Rule 16b-3 under the Exchange Act and the
"outside director" requirement of Code Section 162(m). The members of the
Committee shall be designated by the Board. A majority of the members of the
Committee (but not fewer than two) shall constitute a quorum. The vote of a
majority of a quorum or the unanimous written consent of the Committee shall
constitute action by the Committee.
 
     (b) Selection and Grant.  The Committee shall have the authority to
determine the Employees (if any) to whom Awards will be granted under this Plan,
the type of Award or Awards to be made, and the nature,
 
                                      IV-9
<PAGE>   206
 
amount, pricing, timing, and other terms of Awards to be made to any one or more
of these individuals, subject to the terms of this Plan.
 
     (c) Construction and Interpretation.  The Committee shall have the power to
interpret and administer this Plan and Award Agreements, and to adopt, amend and
rescind related rules and procedures. All questions of interpretation and
determinations with respect to this Plan, the number of shares of Stock, Stock
Appreciation Rights, or units or other Awards granted, and the terms of any
Award Agreements, the adjustments required or permitted by Section 7, and other
determinations hereunder shall be made by the Committee and its determination
shall be final and conclusive upon all parties in interest. In the event of any
conflict between an Award Agreement and any non-discretionary provisions of this
Plan, the terms of this Plan shall govern.
 
     (d) Express Authority (and Limitations on Authority) to Change Terms of
Awards.  Without limiting the Committee's authority under other provisions of
this Plan (including Sections 7 and 9), but subject to any express limitations
of this Plan (including under Sections 7 and 9), the Committee shall have the
authority to accelerate the exercisability or vesting of an Award, to extend the
term or waive early termination provisions of an Award (subject to the maximum
ten-year term under Section 4(b)), to waive the Corporation's rights with
respect to an Award or restrictive conditions of an Award (including forfeiture
conditions), and (subject to stockholder approval) to reduce by amendment the
exercise or purchase price of an outstanding Award, with or without adjusting
any holding period or other terms of the Award, in any case in such
circumstances as the Committee deems appropriate.
 
     (e) Rule 16b-3 Conditions; Bifurcation of Plan.  It is the intent of the
Corporation that this Plan and Share-Based Awards hereunder satisfy and be
interpreted in a manner, that, in the case of Participants who are or may be
Insiders, satisfies any applicable requirements of Rule 16b-3, so that these
persons will be entitled to the benefits of Rule 16b-3 or other exemptive rules
under Section 16 under the Exchange Act and will not be subjected to avoidable
liability thereunder as to Awards intended to be entitled to the benefits of
Rule 16b-3. If any provision of this Plan or of any Award would otherwise
frustrate or conflict with the intent expressed in this Section 8(e), that
provision to the extent possible shall be interpreted and deemed amended so as
to avoid such conflict. To the extent of any remaining irreconcilable conflict
with this intent, the provision shall be deemed disregarded as to Awards
intended as Rule 16b-3 exempt Awards. Notwithstanding anything to the contrary
in this Plan, the provisions of this Plan may at any time be bifurcated by the
Board or the Committee in any manner so that certain provisions of this Plan or
any Award Agreement intended (or required in order) to satisfy the applicable
requirements of Rule 16b-3 are only applicable to Insiders and to those Awards
to Insiders intended to satisfy the requirements of Rule 16b-3.
 
     (f) Limitations Prior to Expiration of Rule 16b-3 Transition
Period.  Notwithstanding any other provision of this Plan, any Award granted to
an Insider prior to September 1, 1995 (or any other date at which the transition
period for purposes of new Rule 16b-3, as to this Plan, expires) is subject to
the following additional limitations:
 
          (1) the Award may provide for the issuance of shares of Stock as a
     stock bonus for no consideration other than services rendered; and
 
          (2) in the event of an Award under which shares of Stock are or in the
     future may be issued for any other type of consideration, the amount of the
     consideration either (A) shall be equal to the minimum amount (such as the
     par value of the shares) required to be received by the Corporation to
     comply with applicable state law, or (B) shall be equal to or greater than
     50% of the Fair Market Value of the shares of Stock on the date of the
     Award; provided that in the case of Restricted Stock Awards, the amount
     shall equal the minimum lawful amount (but not more than 10% of the market
     value of the Stock subject to the Award on the Award Date) and any right to
     purchase the Restricted Stock must be exercised within 60 days of the Award
     Date.
 
     (g) Delegation and Reliance.  The Committee may delegate to the officers or
employees of the Corporation the authority to execute and deliver those
instruments and documents, to do all acts and things, and to take all other
steps deemed necessary, advisable or convenient for the effective administration
of this
 
                                      IV-10
<PAGE>   207
 
Plan in accordance with its terms and purpose, except that the Committee may not
delegate any discretionary authority to grant or amend an award or with respect
to substantive decisions or functions regarding this Plan or Awards as these

under this Plan, the Board and the Committee may obtain and may rely upon the

          (2) No Assurance of Employment.  Nothing contained in this Plan (or in
     any other documents related to this Plan or to any Award) shall confer upon
     any Employee or Participant any right to continue in the employ or other
     service of the Corporation or any Subsidiary or constitute any contract (of
     employment or otherwise) or limit in any way the right of the Corporation
     or any Subsidiary to change a person's compensation or other benefits or to
     terminate the employment of a person with or without cause.
 
     (c) Effective Date; Duration.  This Plan has been adopted by the Board of
Directors of the Corporation and approved by Lockheed Corporation and Martin

after such date in any manner that would have been permitted prior to such date,
except that no such amendment shall increase the number of shares subject to,
comprising or referenced in such Award.

exercise, conversion, operation and vesting of Awards, and the issuance and
delivery of shares of Stock and/or other securities or property or the payment
of cash under this Plan, Awards or Award Agreements, are subject to compliance
with all applicable federal and state laws, rules and regulations (including but
not limited to state and federal insider trading, registration, reporting and
other securities laws and federal margin requirements) and to such approvals by
any listing, regulatory or governmental authority as may, in the opinion of
counsel for the Corporation, be necessary or advisable in connection therewith.
Any securities delivered under this Plan shall be subject to such restrictions
(and the person acquiring such securities shall, if requested by the
Corporation, provide such evidence, assurance and representations to the
Corporation as to compliance with any thereof) as the Corporation may deem
necessary or desirable to assure compliance with all applicable legal
requirements.
 
     (f) Applicable Law.  This Plan, Award Agreements and any related documents
and matters shall be governed in accordance with the laws of the State of
Maryland, except as to matters of Federal law.

to limit the authority of the Corporation, the Board or the Committee to grant
awards or authorize any other compensation, with or without reference to the
Stock, under any other plan or authority.

     The Stock Unit Account of each Director shall be credited on each Award
Date with a number of Units determined by dividing $10,000 by the Average Fair
Market Value of the Common Stock on the Award Date. A Director who is not

Award for the applicable year.
 
     4.2.  Dividend Equivalents; Dividend Equivalent Stock Account.
 
     (a) Allocation of Dividend Equivalents.  Each Director shall be entitled to
receive Dividend Equivalents on the Units credited to his or her Stock Unit
Account and Dividend Equivalent Account, whether before or after a termination
of service, which Dividend Equivalents shall be credited to the Director's
Dividend Equivalent Stock Account in accordance with Section 4.2(b) below.
 
     (b) Dividend Equivalent Stock Account.  The Director's Dividend Equivalent
Stock Account shall be credited with an additional number of Units determined by
dividing the amount of Dividend Equivalents by the Fair Market Value of a share
of Common Stock as of each dividend payment date. The Units credited to a
Director's Dividend Equivalent Stock Account shall be allocated (for purposes of
distribution) in accordance with Section 4.4(b) and shall be subject to
adjustment in accordance with Section 4.5.
 
     4.3.  Vesting of Stock Unit Account and Dividend Equivalent Stock Account.

Section 4.4, each Director shall be entitled to receive a distribution of his or
her Accounts upon a termination of service (including but not limited to a
retirement or resignation) as a Director of the Corporation.
 
                                       V-2
<PAGE>   213
 
     (b) Manner of Distribution.  The benefits payable under this Plan shall be
distributed to the Director (or, in the event of his or her death, the
Director's Beneficiary) in a lump sum, unless the Director elects in writing (on
forms provided by the Corporation) by the time specified in Section 4.4(f), to
receive a distribution of his or her benefits in respect of such Units in
approximately equal annual installments (before giving effect to
post-termination crediting of additional Dividend Equivalents before the
applicable payment date) for up to five years thereafter. Elections with respect
to any Units in the Stock Unit Account shall apply to all Dividend Equivalent
Units attributable to those Stock Units, and to all Dividend Equivalent Units
attributable to those Dividend Equivalent Units. Installment payments shall
commence as of the date benefits become distributable under Section 4.4(a).
Notwithstanding the foregoing, if the vested balance remaining in a Director's
Stock Unit Account and Dividend Equivalent Stock Account is less than 50 shares,
then the remaining balance shall be distributed in shares in a lump sum.
 
     (c) Effect of Death or Disability.  Notwithstanding Sections 4.4(a) and
(b), if a Director's service as a director terminates by reason of Disability,
or a Director or former Director dies, the distribution of a Director's Accounts
(including remaining Account balances of a former Director) shall be made
immediately in a lump sum.
 
     (d) Form of Distribution.  Stock Units credited to a Director's Stock Unit
Account and Dividend Equivalent Stock Account shall be paid and distributed by
means of a distribution of an equivalent whole number of shares of the Common
Stock. Fractions shall be accumulated and converted to Units, but any fractional
interest in a Unit shall be paid in cash on final distribution.
 
     (e) Sub-Accounts.  The Administrator shall retain sub-accounts of a
Director's Accounts as may be necessary to determine which Units are subject to
any distribution elections under Section 4.4(b).
 
     (f) Timing of Elections.  A Director may elect an installment distribution
as provided in Section 4.4(b) only with respect to Units credited on a June 1
which is at least 12 months following his or her election. Notwithstanding the
preceding sentence, a Director's election to receive an installment distribution
may be made (i) with respect to Units to be credited on June 1, 1995, within 30
days after the Merger (or, if later, at the time described in clause (ii)), and
(ii) with respect to Units credited during the Director's first year of service
on the Board, within 30 days after the Director commenced service as a Director
(but in any event prior to the date on which the Units are credited).
 
     4.5.  Adjustments in Case of Changes in Common Stock.  If there shall occur
any recapitalization, stock split (including a stock split in the form of a
stock dividend), reverse stock split, merger, combination, consolidation, or
other reorganization or any extraordinary non-cash dividend or other
extraordinary distribution in respect of the Stock (whether in the form of
Stock, other securities, or other property), or any split-up, spin-off,
extraordinary redemption, or exchange of outstanding Stock, or there shall occur
any other similar corporate transaction or event in respect of the Stock, or a
sale of substantially all the assets of the Corporation as an entirety,
proportionate and equitable adjustments consistent with the effect of such event
on stockholders generally (but without duplication of benefits if Dividend
Equivalents are credited) shall be made in the number and type of shares of
Common Stock (or other cash, property or securities in respect thereof)
reserved, and of Units, under this Plan.
 
     4.6.  Corporation's Right to Withhold.  The Corporation shall satisfy state
or federal income tax withholding obligations, if any, arising upon distribution
of a Director's accounts by reducing the number of shares of Common Stock
otherwise deliverable to the Director by the appropriate number of shares (based
on the Average Fair Market Value) required to satisfy such tax withholding
obligation. If the Corporation, for any reason, cannot satisfy the withholding
obligation in accordance with the preceding sentence, the Director shall pay or
provide for payment in cash of the amount of any taxes which the Corporation may
be required to withhold with respect to the benefits hereunder.
 
     4.7.  Limitations on Rights Associated with Units.  A Director's Accounts
shall be memorandum accounts on the books of the Corporation. The Units credited
to a Director's Accounts shall be used solely as a device for the determination
of the number of shares of Common Stock to be eventually distributed to such
Director in accordance with this Plan. The Units shall not be treated as
property or as a trust fund of any kind,
 
                                       V-3
<PAGE>   214
 
although the Corporation shall reserve shares to satisfy its obligations under
this Plan. All shares of Common Stock or other amounts attributed to the Units
shall be and remain the sole property of the Corporation, and each Director's
rights in the Units is limited to the right to receive shares of Common Stock in
the future as herein provided. No Director shall be entitled to any voting or
other stockholder rights with respect to Units granted under this Plan. The
number of Units credited under this Section shall be subject to adjustment in
accordance with Section 4.5.
 
     4.8.  Restrictions on Resale.  Stock distributed in respect of those Stock
Units that were first credited under Section 4.1 within six months of the
distribution (and Dividend Equivalent Account Units credited under Section 4.2
solely in respect thereof) may be legended or otherwise restricted so as to
prevent a sale of the Stock within six months of the initial crediting of those
Stock Units. Installments shall be deemed payable and paid in the order (i.e.,
last-in, last-out) of the accrual of the underlying Units.
 
                                   ARTICLE V

                                 ADMINISTRATION

self-effectuating. This Plan shall be construed, interpreted and, to the extent
required, administered by the Board or a committee appointed by the Board to act
on its behalf under this Plan. Notwithstanding the foregoing, but subject to
Section 6.1 hereof, the Board shall have no discretionary authority with respect
to the amount, price or timing (as these terms are used under Rule 16b-3(c) of
Rule 16b-3, as promulgated under the Exchange Act ("Rule 16b-3")) of any Award
granted under this Plan and no director shall participate in any decision
relating solely to his or her benefits. Subject to the foregoing, the Board may
resolve any questions and make all other determinations and adjustments required
by this Plan, maintain all the necessary records for the administration of this
Plan, and provide forms and procedures to facilitate the implementation of this
Plan.
 
     5.2.  Decisions Final; Delegation; Reliance; and Limitation on
Liability.  Any determination of the Board or committee made in good faith shall
be conclusive. In performing its duties, the Board or the committee shall be
entitled to rely on public records and on information, opinions, reports or
statements prepared or presented by officers or employees of the Corporation or
other experts believed to be reliable and competent. The Board or the committee
may delegate ministerial, bookkeeping and other non-discretionary functions to
individuals who are officers or employees of the Corporation.
 
     Neither the Corporation nor any member of the Board, nor any other person
participating in any determination of any question under this Plan, or in the
interpretation, administration or application of this Plan, shall have any
liability to any party for any action taken or not taken in good faith under
this Plan or for the failure of an Award (or action or payment in respect of an
Award) to satisfy Code requirements for realization of intended tax
consequences, to qualify for exemption or relief under Rule 16b-3, or to comply
with any other law, compliance with which is not required on the part of the
Corporation.
 
                                   ARTICLE VI

                          PLAN CHANGES AND TERMINATION
 
     6.1.  Amendments.  The Board of Directors shall have the right to amend
this Plan in whole or in part from time to time or may at any time suspend or
terminate this Plan; provided, however, that no amendment or termination shall
cancel or otherwise adversely affect in any way, without his or her written
consent, any Director's rights with respect to Stock Units and Dividend
Equivalents credited to his or her Stock Unit Account or Dividend Equivalent
Stock Account. Notwithstanding the preceding, the provisions of this Plan that
determine the amount, price or timing of benefits related to Stock Units or
Dividend Equivalents shall not be amended more than once every six months (other
than as may be necessary to conform to any applicable changes in the Code or the
rules thereunder), unless such amendment would be consistent with the provisions
of Rule 16b-3(c)(2)(ii) (or any successor provision).

     6.2.  Term.  This Plan shall continue for a period of 10 years following

instrument in writing, and this Plan shall be terminated at the time therein set
forth, and all Directors shall be bound thereby.
 
     6.3.  Distribution of Shares.  If this Plan terminates pursuant to Section
6.2, the distribution of the Accounts of a Director shall be made at the time
provided in Section 4.4(a) and in a manner consistent with the elections made
pursuant to Section 4.4(b).
 
                                  ARTICLE VII

                                 MISCELLANEOUS
 
     7.1.  Limitation on Directors' Rights.  Participation in this Plan shall
not give any Director the right to continue to serve as a member of the Board or
any rights or interests other than as herein provided. No Director shall have
any right to any payment or benefit hereunder except to the extent provided in
this Plan. This Plan shall create only a contractual obligation on the part of
the Corporation as to such amounts and shall not be construed as creating a
trust. This Plan, in and of itself, has no assets. Directors shall have only the
rights of general unsecured creditors of the Corporation with respect to amounts
credited or vested and benefits payable, if any, on their Accounts.
