                              PARENT CORPORATION,
 
                          MARTIN MARIETTA CORPORATION
 
                                      AND
 
                              LOCKHEED CORPORATION
 
     THIS AGREEMENT AND PLAN OF REORGANIZATION, dated as of August 29, 1994
(this "Agreement"), is among Parent Corporation ("Parent"), Martin Marietta
Corporation ("Martin Marietta") and Lockheed Corporation ("Lockheed").
 
     WHEREAS, Martin Marietta is a corporation duly organized and existing under
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
outstanding capital stock of Parent; and
 
     WHEREAS, the Boards of Directors of Martin Marietta and Lockheed deem it
advisable and in the best interest of their respective stockholders that each
corporation become a subsidiary of Parent pursuant to the mergers hereafter
provided for, and desire to make certain representations, warranties and
agreements in connection with such mergers;
 
     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
"Atlantic Sub Merger"). Martin Marietta shall be the surviving corporation in
the Atlantic Sub Merger and as a result thereof shall become a wholly owned
subsidiary of Parent.
 
     (b) Pursuant to the Atlantic Sub Merger:
 
          (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
 
                                       I-1
<PAGE>   6
 
     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
     into and become 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

contemplated thereby, shall be submitted for approval to the holders of shares

                                       I-3
<PAGE>   8
 
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
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

     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>   11
 
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>   12
 
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
been no material adverse change in the business, prospects, results of
operations or financial condition of Martin Marietta and its Subsidiaries taken
as a whole.
 
     SECTION 4.10 Investigations; Litigation.  Except as described in any of the
documents referred to in Section 4.4:
 
          (a) no material investigation or review by any governmental entity
     with respect to Martin Marietta or any of its Subsidiaries is pending (or,
     to Martin Marietta's knowledge, threatened) nor has 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
Information.  None of the information with respect to Martin Marietta or its
Subsidiaries or the Atlantic Sub Merger to be included in the Joint Proxy
Statement (as defined herein) or the Registration Statement (referred to in
Section 6.3) 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
Martin Marietta 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
Martin Marietta with respect to information supplied in writing by Lockheed or
any affiliate of Lockheed specifically for inclusion in the Joint Proxy
Statement. The letters to stockholders, notices of meeting, joint proxy
statement and forms of proxies to be distributed to stockholders in connection
with the Mergers, and any schedules required to be filed with the SEC in
connection therewith are collectively referred to herein as the "Joint Proxy
Statement".
 
     SECTION 4.12 Accounting Matters.  Neither Martin Marietta nor, to its
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 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"). As
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
person. As used in this definition, "control" (including, with its correlative
meanings, "controlled by" and "under common control with") shall mean
possession, directly or indirectly, of power to direct or cause the direction of
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.

Martin Marietta's employee benefit plans) and is not an "interested stockholder"
of Lockheed within the meaning of Section 203 of the Delaware Statute.
 
     SECTION 4.15 Tax Matters.  (a) All federal, state, local, and foreign tax
returns required to be filed by or on behalf of Martin Marietta and each of its
Subsidiaries have been timely filed, and all returns filed are complete and
accurate to the knowledge of Martin Marietta. 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 Martin Marietta or any of its Subsidiaries,
except as adequately reserved against in the most recent financial statements
contained in the documents referred to in Section 4.4. All assessments for
taxes, interest, additions, and penalties due with respect to completed and
settled examinations or concluded litigation have been paid.
 
     (b) No stock or securities will be issued to any person other than the
securityholders of Martin Marietta, Lockheed or Parent in connection with the
transactions contemplated by this Agreement; except in connection with employee
benefit programs or Martin Marietta's dividend reinvestment plan, the management
of Martin Marietta has no plan or intention for Parent to issue any stock other
than Parent Common Stock and Parent Preferred Stock in connection with the
transactions contemplated by this Agreement; except in connection with employee
benefit programs, Martin Marietta's dividend reinvestment plan or otherwise in
the ordinary course of business, the management of Martin Marietta has no plan
or intention for Parent to redeem or otherwise reacquire any Parent Preferred
Stock or Parent Common Stock to be issued in connection with the transactions
contemplated by this Agreement; and the management of Martin Marietta has no
plan or intention to terminate the existence of Parent or to merge Parent with
any other corporation.
 
     (c) Martin Marietta is not aware of any plan or intention of Parent to
liquidate Martin Marietta, to merge Martin Marietta with or into another
corporation or to sell or otherwise dispose of the stock of Martin Marietta
except for transfers of stock to corporations controlled by Parent. For purposes
of this representation, "control" is defined in Section 368(c) of the Code.

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

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>   14
 
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>   15
 
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;
 
          (c) each definitive proxy statement filed by Lockheed with the SEC

     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>   16
 
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. 1 6.
 
     SECTION 5.13  Lockheed Rights Plan.  Under the terms of the Lockheed Rights
Plan, the transactions contemplated by this Agreement will not cause a
Distribution Date to occur or cause the rights issued pursuant to the Lockheed
Rights Plan to become exercisable, and, by action taken prior to the Merger
Date,
 
                                      I-12
<PAGE>   17
 
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.
 
     (b) No stock or securities will be issued to any person other than the
securityholders of Lockheed, Martin Marietta or Parent in connection with the
transactions contemplated by this Agreement; except in connection with employee
benefit programs, the management of Lockheed has no plan or intention for Parent
to issue any stock other than Parent Common Stock and Parent Preferred Stock in
connection with the transactions contemplated by this Agreement; except in
connection with employee benefit programs or otherwise in the ordinary course of
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
to be issued in connection with the transactions contemplated by this Agreement;
and the management of Lockheed has no plan or intention to terminate the
existence of Parent or to merge Parent with any other corporation.
 
     (c) Following the Pacific Sub Merger, Lockheed will hold at least 90
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
assets to a corporation controlled by Lockheed; or to cause Lockheed to issue
any shares of capital stock to any person other than Parent. For purposes of
this representation, "control" is defined by Section 368(c) of the Code.

information to any other party. Notwithstanding any provision of this Agreement

     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

     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

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

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

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

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.

assets, issuance of securities in exchange for cash or securities or other
property, liquidation or dissolution) involving Martin Marietta other than the

     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

of Lockheed, and (b) the current policies of directors' and officers' liability
insurance and fiduciary liability insurance maintained by Martin Marietta and

from facts or events which occurred on or before the Merger Date.

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

for comfort letters delivered by independent accountants in connection with

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

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).

     any such extension or waiver shall be valid only if set forth in an
     instrument in writing signed on behalf of such party.

                          PLAN AND AGREEMENT OF MERGER
 
     THIS PLAN AND AGREEMENT OF MERGER dated as of August 29, 1994 is among
Lockheed Corporation, a Delaware corporation ("Lockheed"), Pacific Sub, Inc., a
Delaware corporation ("Pacific Sub"), and Parent Corporation, a Maryland
corporation ("Parent"). Lockheed and Pacific Sub are hereinafter sometimes
collectively referred to as the Constituent Corporations.
 
     All of the outstanding stock of Pacific Sub is owned by Parent and all of
the outstanding stock of Parent is owned, in equal amounts, by Lockheed and by
Martin Marietta Corporation, a Maryland corporation ("Martin Marietta"). Parent
will be authorized, at the time of the merger provided for herein, to issue
820,000,000 shares of capital stock of which 50,000,000 shares will be series
preferred stock, $1.00 par value, 20,000,000 shares will be Series A Preferred
Stock $1.00 par value, and 750,000,000 shares will be Common Stock, $1.00 par
value ("Parent Common Stock").
 
     This Plan and Agreement of Merger is being entered into pursuant to a Plan
and Agreement of Reorganization dated as of August 29, 1994 among Martin
Marietta, Lockheed and Parent (the "Reorganization Agreement"). Capitalized
terms used but not defined herein have the meanings given to them in the
Reorganization Agreement.
 
                                   ARTICLE I
 
     1.1  On the Merger Date (as defined in paragraph 1.6) Pacific Sub shall
merge into Lockheed (the "Pacific Sub Merger") and the separate existence of
Pacific Sub shall cease. Lockheed shall be the surviving corporation in the
Pacific Sub Merger (hereinafter sometimes referred to as the "Surviving
Corporation") and its separate corporate existence, with all its purposes,
objects, rights, privileges, powers and franchises, shall continue unaffected
and unimpaired by the Pacific Sub Merger.
 
     1.2  The Surviving Corporation shall succeed to all of the rights,
privileges, powers and franchises, as well of a public as of a private nature,
of the Constituent Corporations, all of the properties and assets of the
Constituent Corporations and all of the debts, choses in action and other
interests due or belonging to the Constituent Corporations and shall be subject
to, and responsible for, all of the debts, liabilities and duties of the
Constituent Corporations with the effect set forth in the General Corporation
Law of Delaware.
 
     1.3  If, at any time after the Merger Date, the Surviving Corporation shall
consider or be advised that any deeds, bills of sale, assignments, assurances or
any other actions or things are necessary or desirable to vest, perfect or
confirm of record or otherwise in the Surviving Corporation its right, title or
interest in, to or under any of the rights, properties or assets of Pacific Sub
acquired or to be acquired by the Surviving Corporation as a result of, or in
connection with, the Pacific Sub Merger or to otherwise carry out this Plan and
Agreement of Merger, the officers and directors of the Surviving Corporation
shall and will be authorized to execute and deliver, in the name and on behalf
of the Constituent Corporations or otherwise, all such deeds, bills of sale,
assignments and assurances and to take and do, in the name and on behalf of the
Constituent Corporations or otherwise, all such other actions and things as may
be necessary or desirable to vest, perfect or confirm any and all right, title
and interest in, to and under such rights, properties or assets in the Surviving
Corporation or to otherwise carry out this Plan and Agreement of Merger.
 
     1.4  The Certificate of Incorporation and the Bylaws of Lockheed, in each
case as amended to and including the Merger Date, shall be the Certificate of
Incorporation and Bylaws of the Surviving Corporation and shall thereafter
continue to be its Certificate of Incorporation and its Bylaws until changed as
provided therein and by law.
 
     1.5  The directors and officers of Lockheed immediately prior to the Merger
Date shall be the directors and officers of the Surviving Corporation and shall
thereafter continue in office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation.

     1.6  If this Plan and Agreement of Merger is duly adopted by the
stockholders of each of the Constituent Corporations in accordance with the
Delaware General Corporation Law and the respective Certificates of
Incorporation and Bylaws of the Constituent Corporations and is not terminated
under paragraph 3.1, a Certificate of Merger with respect to the Pacific Sub
Merger shall be promptly filed and recorded in accordance with the Delaware
General Corporation Law. The Pacific Sub Merger shall become effective at the
time and date of such filing or at such date and time otherwise specified in the
Certificate of Merger (such time and date are herein collectively referred to as
the "Merger Date").
 
                                   ARTICLE II
 
     2.1  On the Merger Date, by virtue of the Pacific Sub Merger and without
further action by the holder thereof, each share of the common stock, par value
$1.00 per share, of Pacific Sub outstanding immediately prior thereto shall be
converted into and become one share of the common stock, par value $1.00 per
share, of the Surviving Corporation ("Surviving Corporation Common Stock").
 
     2.2  On the Merger Date, by virtue of the Pacific Sub Merger and without
further action by the holder thereof, each share of common stock, par value
$1.00 per share, of Lockheed outstanding immediately prior thereto (other than
shares of Lockheed Common Stock held in the treasury of Lockheed or owned by
Martin Marietta or any Subsidiary of Martin Marietta, which shall be cancelled
and cease to exist immediately upon the Merger Date) shall be converted into and
become the right to receive 1.63 shares of Parent Common Stock, except that if
the application of such ratio would otherwise result in conversion into a
fractional number of shares of Parent Common Stock, cash payments will be made
to holders of Lockheed Common Stock in respect of such fractional share in an
amount equal to such fractional part of a share of Parent Common Stock
multiplied by the closing price of Parent Common Stock on the New York Stock
Exchange 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.
 
     2.3  On and after the Merger Date, the holders of certificates theretofore
representing shares of Lockheed Common Stock (other than shares held in the
treasury of Lockheed or owned by Martin Marietta or any Subsidiary of Martin
Marietta), on surrender of such certificates to an agent or agents designated
for that purpose by Parent, shall be entitled to receive in exchange therefor
certificates representing the number of shares of Parent Common Stock into which
the shares of Lockheed Common Stock theretofore represented by the surrendered
certificates shall have been converted in the Pacific Sub Merger; provided,
however, that if any such holder is not registered on the stock transfer records
of Lockheed as the holder of the shares of Lockheed Common Stock represented by
a certificate so surrendered, such certificate shall be accompanied by all
documents required to evidence such holder's rights to the shares represented
thereby and by payment for any applicable stock transfer or other taxes.
 
     2.4  All shares of Parent Common Stock into which shares of Lockheed Common
Stock are converted on the Merger Date pursuant to paragraph 2.2 shall be
deemed, for all corporate purposes, to have been issued by Parent on such Date.
On and after such Date and prior to the surrender, pursuant to paragraph 2.3, of
any certificate theretofore representing shares of Lockheed Common Stock, such
certificate shall, for all corporate purposes (including, without limitation,
entitlement to vote and to the receipt of dividends), be treated as representing
the number of shares of Parent Common Stock into which such shares of Lockheed
Common Stock, as the case may be, shall have been converted in the Pacific Sub
Merger. No holder of a certificate or certificates which immediately prior to
the Merger Date represented shares of Lockheed Common 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. 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
represented by the certificates issued upon such surrender.

                                  ARTICLE III
 
     3.1  Notwithstanding the approval and adoption of this Plan and Agreement
of Merger by the stockholders of Lockheed and Pacific Sub, this Plan and
Agreement of Merger shall terminate forthwith in the event that the
Reorganization Agreement shall be terminated as therein provided. In the event
of the termination of this Plan and Agreement of Merger as provided above, this
Plan and Agreement of Merger shall forthwith become void and there shall be no
liability on the part of any of the parties hereto.
 
     3.2  This Plan and Agreement of Merger may be amended to the extent
permitted by applicable law, but only pursuant to an amendment to the
Reorganization Agreement approved in the manner therein provided. If any such
amendment to the Reorganization Agreement is so approved, any amendment to this
Plan and Agreement of Merger required by such amendment to the Reorganization
Agreement shall be effected by the parties hereto by action taken by their
respective Boards of Directors.
 
     3.3  This Plan and Agreement of Merger may be executed in one or more
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to each of the other parties.
 
     3.4  This Plan and Agreement of Merger shall be governed by and construed
in accordance with the laws of the State of Delaware.
 
     IN WITNESS WHEREOF, this Plan and Agreement of Merger has been executed by
each of the parties hereto by their duly authorized officers, as of the date
first above written.
