PART I

ITEM 1.       BUSINESS

General

  Lockheed Martin Corporation (the "Corporation," which also may be referred to
as "we," "us," or "our") is a highly diversified global enterprise that
principally researches, designs, develops, manufactures and integrates advanced
technology products and services.  In March 1995, we were formed by combining
the businesses of Martin Marietta Corporation ("Martin Marietta") and Lockheed
Corporation ("Lockheed").  We are a Maryland corporation.

  Throughout this Form 10-K, we "incorporate by reference" information from
parts of other documents filed with the Securities and Exchange Commission
("SEC"). The SEC allows us to disclose important information by referring to it
in this manner and you should review such information.

  Our principal executive offices are located at 6801 Rockledge Drive, Bethesda,
Maryland 20817.  Our telephone number is (301) 897-6000.  Our home page on the
Internet is www.lockheedmartin.com.  You can learn more about us by reviewing
our SEC filings on that web site.  We are making our web site content available
for your information only.  It should not be relied upon for investment
purposes, nor is it incorporated by reference into this Form 10-K.


Transaction Agreement with COMSAT Corporation

     In September 1998, we entered into an agreement with COMSAT Corporation
("COMSAT") to combine COMSAT with one of our subsidiaries in a two-phase
transaction with 

                                       2
<PAGE>
 
an estimated value for COMSAT of approximately $2.7 billion as of that date. In
the first phase of this transaction, acting through a subsidiary, we commenced a
cash tender offer to purchase up to 49% of the outstanding shares of COMSAT
common stock at $45.50 per share, subject to certain adjustments.

     Subject to the terms of the agreement, the tender offer will be extended
for periods of up to 60 days until at least the earlier of (i) September 18,
1999 or (ii) satisfaction of certain conditions to closing, including (1) the
condition that at least one-third of the outstanding shares of COMSAT common
stock be validly tendered (and not withdrawn), (2) the approval of the merger by
the COMSAT stockholders and (3) receipt of certain regulatory approvals,
including Federal Communications Commission ("FCC") approval for us to purchase
more than 10% of COMSAT's outstanding shares, and antitrust clearance by the
Department of Justice. Currently, the tender offer expires on May 3, 1999. Until
we complete the merger, we will account for the COMSAT investment resulting from
the tender offer under the equity method of accounting.

     The second phase of the transaction is the completion of the merger through
the exchange of one share of our common stock for each share of COMSAT common
stock not purchased in the tender offer. COMSAT shareholders are voting on the
proposed merger at COMSAT's annual meeting of stockholders scheduled for June
18, 1999. We will account for our merger with COMSAT under the purchase method
of accounting. Consummation of the merger is subject to, among other things, the
closing of the tender offer, the enactment of federal legislation necessary to
allow us to acquire the remaining COMSAT shares and certain additional
regulatory approvals. The speed at which the legislative process progresses will
affect the timing of the second phase of the transaction. If the first phase
tender offer is consummated and if the necessary legislation is not enacted or
the additional
                                       3
<PAGE>
 
regulatory approvals are not obtained, we will not be able to consummate the
merger nor will we be able to control COMSAT.

     Current FCC regulations do not allow a company that is not an "FCC
authorized common carrier" to purchase more than 10% of COMSAT. We have filed an
application with the FCC for our acquisition subsidiary to acquire a COMSAT
common carrier subsidiary through a merger and for FCC designation of that
subsidiary as an FCC authorized common carrier allowed to purchase up to 49% of
COMSAT. On January 21, 1999, the Chairman of the House Committee on Commerce and
the Chairman of the Senate Subcommittee on Communications sent a letter to the
FCC urging it not to take any action to permit any company to purchase more than
10% of COMSAT prior to Congress amending the Communications Satellite Act of
1962 that would involve privatization of Intelstat and lifting ownership limits
on COMSAT.

     If the FCC does not proceed with its review of our filings related to the
tender offer or does not otherwise proceed on the schedule that we anticipate,
we may not be able to complete the tender offer by September 18, 1999. If the
tender offer is not completed by this date, under the terms of the merger
agreement, any of the parties may terminate the merger agreement. The parties
may elect not to do this or elect to amend the merger agreement so that the
merger can be completed at a date later than September 18, 1999. In addition, if
Congress does not make progress on satellite reform legislation, even if the
tender offer is completed, the merger may not occur in 1999. On the other hand,
if Congress timely acts on the legislation, the merger may occur in 1999.
 
  In August 1998, we formed Lockheed Martin Global Telecommunications, Inc., a 
wholly-owned subsidiary ("LMGT"), to focus on expanding our presence in the
global telecommunications services market. Subsequently, we transferred certain
investments in
                                       4
<PAGE>
 
joint ventures and business units from some of our sectors to LMGT. The transfer
was effective in January 1999. If the COMSAT transaction is consummated, we
intend to combine COMSAT's operations with LMGT's operations.

  For business segment reporting in our consolidated financial statements, the
Space & Strategic Missiles, Electronics, Aeronautics and Information & Services
sectors each comprise reportable business segments.  The Energy & Environment
sector and our other activities are reported as Energy and Other.

  Comparative segment revenues, profits and related financial information for
1998, 1997 and 1996 are provided in the table entitled "Selected Financial Data
by Business Segment" in "Note 17 - Information on Industry Segments and Major
Customers" on page 44 of our 1998 Annual Report to Shareholders.


Space & Strategic Missiles Sector
- ---------------------------------

  Our Space & Strategic Missiles sector conducts most of its business through
its Astronautics, Missiles & Space and Michoud Space Systems companies.  A
substantial portion of the sector's activities involves classified programs for
the U.S. Government.  In 1998, the sector's net sales represented 28.4% of our
total net sales.

     The sector's Astronautics company designs, develops, manufactures and
integrates advanced technology systems for space and defense. Principal products
include the Titan and Atlas family of launch vehicles. Through our joint venture
with two Russian aerospace companies, (which joint venture is consolidated in
our financial statements), we also provide Proton rocket launch vehicle
services. In 1998, we experienced postponements of some Proton launches of
commercial satellites due to delays in payload deliveries. In 1998, the U.S. Air
Force awarded us a contract modification to complete the production of Titan IV
space launch vehicles and provide launch services through 2002. In August 1998,
Titan II and IV booster launches were delayed 

                                       6
<PAGE>
 
following the failure of a mission. In early 1999, the U.S. Air Force, after
extensive analysis, announced that the Titan launch vehicles may return to
operational status. In addition, in 1998, we received separate agreements from
the U.S Air Force to develop the Evolved Expendable Launch Vehicle ("EELV") and
to provide launch services for nine U.S. Government missions using an EELV to be
named "Atlas V."

  The sector's Missiles & Space company designs, develops, manufactures and
integrates strategic missiles and spacecraft for communications, Earth
observation, scientific and navigation missions for military and civilian
government agencies and commercial customers.  Principal products include the
Trident II submarine-launched fleet ballistic missile and MILSTAR defense
communications satellites.  The company also plays a role in the National
Aeronautics & Space Administration's ("NASA") international Space Station
program.  Through its Commercial Space Systems unit, the company markets and
sells communications spacecraft to commercial telecommunications customers,
including some customers in which we have an ownership interest.

  During 1998, the Missiles & Space company's Theater High Altitude Area Defense
("THAAD") system failed to achieve an intercept of a ballistic target during
testing.  In response to this flight failure, we agreed with the U.S. Army to a
contract modification providing for cost sharing in the event a pre-determined
number of direct hits is not achieved during 1999.

  In 1998, the Missiles & Space company discovered a manufacturing defect in
traveling wave tube amplifiers (TWTAs), which are satellite components made by
another company, following observed failures of TWTAs in some of its orbiting
satellites.  The investigation and resolution of the defect led to a decision to
ground and repair five satellites, including one 

                                       7
<PAGE>
 
already shipped and awaiting launch. The delay moved the expected launch dates
of some of these satellites from 1998 to 1999.

  The sector's Michoud Space Systems company manufactures the Super Lightweight
Tank, the latest iteration of the Space Shuttle External Tank for NASA.  This
company also designs, develops and manufactures, for us and commercial
customers, large aluminum and composite structures (including fuel tanks for
space vehicles), cryogenic propellant feed systems and thermal protection
systems for cryogenic structures.  Currently, Michoud is developing the X-33
liquid oxygen tanks and main propellant feed system.

     Space Imaging, LP, which we principally own with Raytheon Company, collects
and distributes a wide variety of satellite- and aerially-derived digital Earth
information products. In 1999, we expect Space Imaging to launch an advanced
commercial imaging satellite built by the sector's Missiles & Space company.  In
1998, during testing, this satellite's gyroscopic components showed an
unacceptably short on-orbit lifetime prediction.  To undertake the steps
necessary to restore the expected life of the satellite, the first satellite
launch was delayed from late 1998 into 1999.

     During 1998, we reassigned management responsibility for the United Space
Alliance, LLC, which we jointly own with The Boeing Company, from the
Information & Services sector to this sector.  United Space Alliance is
responsible for the day-to-day operation and management of the Space Shuttle
fleet for NASA.  It also performs the modification, testing and checkout
operations required to prepare space shuttles for launch.

                                       8
<PAGE>
 
  The sector is heavily dependent on both military and civilian agencies of the
U.S. Government as customers.  In 1998, U.S. Government customers accounted for
over three-quarters of the sector's net sales.


Electronics Sector
- ------------------

  Our Electronics sector is comprised of numerous business units, engaged mainly
in U.S. defense work.  Major product lines include surface ship and submarine
combat systems; anti-submarine warfare systems; air defense systems; tactical
battlefield missiles; engine controls; radar and fire control systems;
electronic warfare systems; electro-optic and night vision systems; displays;
systems integration of mission specific combat suites; and postal automation
systems. The sector's major lines of business include:  Naval Electronics and
Surveillance Systems; Missiles and Fire Control; Aerospace Electronics; and
Platform Integration.  The sector also has a Control Systems business.  A
portion of the sector's activities involve classified programs for the U.S.
Government.  In 1998, the sector's net sales represented 28.0% of our total net
sales.

  Naval Electronics and Surveillance Systems provides products and services,
including shipboard electronics integration, surface ship and submarine combat
systems, sensors and missile launching systems.  Missiles and Fire Control
produces air defense systems, tactical battlefield missiles and precision guided
weapons and munitions.  Aerospace Electronics manufactures major electronics
subsystems such as:  information warfare and countermeasures systems,
surveillance and reconnaissance systems and space electronics products.
Platform Integration performs systems integration of mission specific combat
suites in areas including anti-submarine warfare, electronic warfare,
surveillance and reconnaissance, and postal automation. Control Systems produces
flight and engine controls, space vehicle power and control systems, hybrid
diesel electronic propulsion 

                                       9
<PAGE>
 
systems and electronics for the rail transportation industry.

     In 1998, we continued our role as a major supplier of shipboard combat
systems for surface combatants for the U.S. Navy.  We are the prime contractor
for the U.S. Navy's AEGIS fleet air defense system and, in 1998, the U.S. Navy
awarded us two new AEGIS contracts: one for future AEGIS program computer
development and one to produce multiple AEGIS weapon systems.

  In 1998, we enhanced our stature as an international business partner through
leadership or membership on teams selected to execute defense programs for
countries in Europe and Asia, and Australia.  These programs involve the
development and deployment of advanced electronic systems on airborne-, naval-
and land-based platforms.  In 1998, several international joint development
groups selected us to participate in their programs.

     In 1998, the Electronics and Aeronautics sectors worked together to enter
the air-launched cruise missile market with a contract to develop and build the
Joint Air-to-Surface Standoff Missile ("JASSM") system for the U.S. Air Force
and Navy.  In April 1998, our wholly-owned subsidiary, Lockheed Martin
Integrated Systems, Inc. ("LMIS"),  was awarded a contract to complete JASSM's
Program Definition and Risk Reduction phase. In November 1998, LMIS executed the
contract for engineering and manufacturing development in a 40-month program.
Production on the missile is expected to begin in early 2001.

     The sector continues to selectively pursue non-defense business
opportunities where it can utilize its technical and large-scale integration
capabilities. Our postal business --  under which we provide material handling
systems and equipment to sort mail, technology for bar code 

                                      10
<PAGE>
 
reading, and address and handwriting recognition systems to the U.S. Postal
Service and international customers -- continues to grow. In 1998, our postal
business obtained contracts from postal agencies in the U.S. and Australia, and
we acquired three companies that manufacture and market high-speed processing
systems, bar code readers and sorters.

     The sector is heavily dependent on the U.S. military as a customer.  In
1998, U.S. Government customers accounted for over two-thirds of the sector's
net sales.


Aeronautics Sector
- ------------------

  Our Aeronautics sector conducts its business through four operating companies:
Aeronautical Systems, Aircraft & Logistics Centers, Skunk Works and Tactical
Aircraft Systems.  A portion of the sector's activities involve classified
programs for the U.S. Government, particularly at Skunk Works.  In 1998, the
sector's net sales represented 22.8% of our total net sales.

  The sector is involved in large defense programs including:

 . F-22 air-superiority fighter -- that has significantly improved capabilities
  over current U.S. Air Force aircraft;

 . F-16 multi-role fighter -- presently the world's premier, low-cost multi-role
  fighter;

 . Joint Strike Fighter -- currently in the concept demonstration phase
  potentially leading to the next generation, multi-role fighter and has the
  potential to be the largest tactical aircraft program in the U.S., and perhaps
  the world;

 . C-130J transport -- latest generation of C-130 Hercules tactical transport
  aircraft; and

 . X-33 reusable launch vehicle -- a subscale demonstrator flight vehicle which
  eventually may 

                                      11
<PAGE>
 
  lead to development of a commercial reusable launch vehicle
  program.

     We are the team leader for the F-22 air superiority fighter aircraft
program.  The F-22 is the latest generation of fighter aircraft and continues to
proceed through its engineering and manufacturing development phase, meeting or
exceeding all key performance parameters.  In 1998, the  F-22 met the flight
test criteria set by the Department of Defense, allowing them to award us an
initial contract for the first two production aircraft -- termed Production
Representative Test Vehicles -- and for long lead procurement for Production Lot
1 (consisting of six aircraft).  The Lot 1 production contract award is
anticipated to occur in late 1999.

  We are the prime contractor on the F-16 "Fighting Falcon" tactical fighter
aircraft and continue to provide upgrades for the U.S Air Force and our
international customers.  To date, we have sold over four thousand of these
aircraft.  In 1998, the United Arab Emirates selected our new "Block 60" F-16 as
its advanced fighter aircraft, and we are working to sign a multi-billion dollar
contract during 1999.

  For the next generation Joint Strike Fighter, various branches of the U.S.
military and other countries' militaries are working together on a set of
requirements that should allow a near-common design.  In 1998,  we completed the
basic aerodynamic design of our Joint Strike Fighter concept and completed
various design reviews.  We also continued to fabricate two concept
demonstration aircraft.  In 2000, we anticipate that flight tests of the concept
demonstration aircraft will be made.   We are one of the two remaining
competitors for the program down-select award, which currently is planned to be
made in 2001.
                                      12
<PAGE>
 
  The C-130J is an advanced technology tactical transport aircraft offering
improved performance and reliability and reduced operating and support cost over
prior C-130 models. The "J" model incorporates state-of-the-art cockpits and
avionics, a more powerful and efficient propulsion system and numerous
manufacturing innovations into a proven, mission-tested airframe. In 1998, we
received Federal Aviation Administration ("FAA") certification for the C-130J
and made nineteen deliveries. As a result of the later than expected FAA
certification due to ice removal and final acceptance issues, we were unable to
complete all of the deliveries planned for 1998. We intend to resolve the 1998
delivery issues and expect to meet our customers' current schedules in 1999.

  Since 1996, we have been working with NASA to develop the X-33, a subscale
technology demonstrator of a reusable launch vehicle. In 1998, we completed the
final design review of the X-33. In 1999, we expect to complete major milestones
pertaining to vehicle assembly and integration leading to the anticipated roll-
out and first flight of a subscale prototype in 2000. We will then decide
whether to proceed with the development of a full-scale, commercial reusable
launch vehicle program.

  We also provide sustaining engineering, modifications and upgrades for
existing aircraft, including the F-117 fighter, the U-2 reconnaissance aircraft,
and earlier model C130s and  are involved in other programs such as the joint
Japan/U.S. production of the F-2 aircraft.

  The sector is dependent on the U.S. military, NASA and international
governments as customers.  In 1998, U.S. Government customers accounted for
approximately one-half of the sector's net sales.

                                      13

Information & Services Sector
- -----------------------------

  Our Information & Services sector provides government and commercial customers
with engineering, scientific, management, technical and information technology
systems and services through numerous business units.  The sector's four primary
lines of business are:  (i) systems integration and command, control,
communications, computer and intelligence ("C4I") systems; (ii) federal
technology services; (iii) state and municipal systems support services; and
(iv) commercial information technology services.  A portion of the sector's
activities involves classified programs for the U.S. Government.  The sector
also provides internal information system support to the Corporation and its
affiliates.  In 1998, the sector's net sales represented approximately 19.8% of
our total net sales.

     Through the sector's systems integration and C4I line of business, in 1998,
we continued to upgrade the U.S. National Air Traffic Control System through a
contract to replace  display systems at 20 FAA Air Route Traffic Control
Centers.  In December 1998, Seattle became the first center to begin operations
with the new system.  In 1998, we expanded our international business.  For
example, we obtained contracts to provide air traffic control for two airports
in China and to design and implement an automated system for the United Kingdom
census.  In addition, we entered into a joint venture in Poland to provide
information technology services in Poland and Eastern Europe.

  Through the sectors' federal technology services line of business, we provide
a wide array of scientific and engineering, information management, operation
and maintenance, logistics, assembly and test and installation services to
governmental agencies and prime contractors.  In 1998, NASA awarded us the
Consolidated Space Operations Contract to consolidate mission and 

                                      14
<PAGE>
 
data services operations at five of NASA's major centers. This is a multi-
billion dollar, five-year contract, with an option for five more years. In
addition, the U.S. Army awarded us, along with two other contractors, a contract
with the potential for revenue of $1.5 billion for the Rapid Response to
Critical System Requirement program to ensure that critical systems maintain
full functionality and operability.

  Services to state and local government customers include systems development,
integration and operational support in the areas of welfare reform, municipal
services, children and family services, transportation, information resource
management and integrated technology solutions.  In late 1998, we enhanced our
stop light and radar photo enforcement business through an acquisition.  In
December 1998, we agreed, subject to regulatory processes, to divest our
communications industry services business, which serves as the North American
Numbering Plan administrator and as the local number portability administrator
for the U.S. and Canada.

     We continue to focus on our commercial information technology services.  In
1998, we won an information technology services contract from Policy Management
Systems Corporation for support related to insurance industry software systems
and automation, administration and information services.  In the fourth quarter
of 1998,  we notified CalComp Technology, Inc. ("CalComp"), our majority-owned
public subsidiary, that we would not increase existing credit to support
CalComp's ongoing operations.  Subsequently, we agreed to provide financing,
subject to certain conditions, for a plan providing for the timely non-

other non-core commercial product operations.

     The sector is dependent on the military and civilian agencies of the U.S.
Government as customers.  In 1998, U.S. Government customers accounted for
nearly three-quarters of the sector's net sales.


Energy & Environment Sector
- ---------------------------

  Our Energy & Environment sector, consisting of nine principal operating
companies,  is in three lines of business:  nuclear operations management for
the DOE, nuclear materials management for the Department of Energy ("DOE") and
technology-driven remediation programs. Under most of the sector's contracts, we
receive a fee for performing management services and are reimbursed for the cost
of operations.  Only the fee we receive is recorded in our net sales and
earnings.  In 1998, the sector's net sales represented less than 1% of our total
net sales.

  As one of the largest management and operations contractors for the DOE, we
manage defense, energy research and environmental programs.  We manage the DOE's
Y-12 facility in Oak Ridge, Tennessee and part of DOE's Nevada Test Site as part
of its defense program area.  In 1998, we received notification of DOE's
intention to extend the Y-12 contract to mid-2001 and, in 1999, we received a
three-year extension for a nuclear waste management subcontract at DOE's
Hanford, Washington site.  In May 1999, our management contract for uranium
enrichment at a former DOE site (now privatized under the United States
Enrichment Corporation) will expire.  In addition, we manage the  laboratories
at Sandia National Laboratories, Oak Ridge National Laboratory and Idaho
National Engineering and Environmental Laboratory.  In 1998, the DOE extended
our Sandia contract for another five  years.  In 1999, the Oak Ridge and Idaho
National Engineering management contracts will undergo competition for a new
contract.  We have decided not to bid on the Idaho National Engineering contract
and have decided to not independently bid on 

                                      16
<PAGE>
 
the Oak Ridge contract, but we may consider other options. For a discussion
relating to pending litigation involving Pit 9 located on the Idaho National
Engineering and Environmental Laboratory reservation, see "Item 3. Legal
Proceedings."

  The sector is heavily dependent on the DOE, and to a much lesser extent, the
Department of Defense  ("DOD"), as customers.  In 1998, U.S. Government
customers accounted for approximately three-quarters of the sector's net sales.

 
Additional Activities
- ----------------------

  In August 1998, we formed LMGT to expand our presence in the global
telecommunications services market. Effective in January 1999, we transferred
the following operations from other sectors to LMGT:

 . our assets and liabilities relating to telecommunication activities of the
  Missiles & Space company, Lockheed Martin Management & Data Systems and
  Lockheed Martin Western Development Laboratories that are engaged in programs
  such as ASIA Cellular Satellite ("ACeS"), Ellipso, and Astrolink /TM/;

 . our investment in Lockheed Martin Intersputnik, Ltd., a strategic venture
  principally owned by us and, and to a lesser extent, owned by Moscow-based
  Intersputnik International Organization of Space Communications, that is
  scheduled to deploy its first satellite in 1999;

 . our 50% investment in Americom Asia-Pacific, LLC, a joint venture with GE
  American Communications, Inc. that is scheduled to launch a satellite in 1999
  that will serve broadcasters in the Asia-Pacific region; and

 . our 30% equity investment in ACeS, recently reincorporated as ACeS
  International Limited, which is to deliver mobile voice and data
  communications
                                      17
<PAGE>
 
  services beginning in late 1999 in the Asia-Pacific region.

  If the COMSAT tender offer and the merger are consummated, we intend to
combine COMSAT's operations with LMGT's operations.

  We also run research laboratories, own real estate and conduct other
miscellaneous activities.  We have approximately a diluted 14% interest (in the
form of convertible preferred stock) in Loral Space & Communications, Ltd. We
are considering monetizing or divesting this interest in 1999, if market
conditions permit and we obtain any necessary Loral agreement. In February 1999,
we reduced our ownership interest in L-3 Communications Corporation from
approximately 25% to 7%.

Patents

  We own numerous patents and patent applications, some of which, together with
licenses under patents owned by others, are utilized in our operations.
Although these patents and licenses are, in the aggregate, important to the
operation of our business, no existing patent, license or other similar
intellectual property right is of such importance that its loss or termination
would, in the opinion of management, materially affect our business.

Raw Materials and Seasonality

  Although certain aspects of our business require relatively scarce raw
materials, we have not experienced difficulty in our ability to obtain raw
materials and other supplies needed in our manufacturing processes, nor do we 
expect this to be an issue in the future. No material portion of our business is
considered to be seasonal.




                                      18

Competition and Risk

  We compete with numerous other contractors on the basis of price, as well as
technical and managerial capability.  Our ability to successfully compete for
and retain such business is highly dependent on technical excellence, management
proficiency, strategic alliances, cost-effective performance and the ability to
recruit and retain key personnel.

     On-going consolidation of the U.S. and global defense and space industries
continues to intensify competition.  Consolidation among U.S. defense, space and
aerospace companies has resulted in a reduction of the number of principal prime
contractors for the DOD and NASA.  As a result of this consolidation, we
frequently partner on various programs with our major suppliers, some of whom
are, from time to time, our competitors on other programs.  We are required to
generate working capital and invest in fixed assets to maintain and expand our 
government business.  Winning the competition for a contract is often the
determinant of whether a competitor is able to remain in that line of business.

                                      19
<PAGE>


     U.S. Government programs are also subject to uncertain future funding
levels, which can result in the extension or termination of programs.  Our
business is also highly sensitive to changes in national and international
priorities and U.S. Government budgets.  For most of this decade, we have been
adversely impacted by U.S. Government budgetary and policy constraints which led
to fewer available contracts.  Recently, the Clinton administration announced
plans to obtain increased budgets for the U.S. military.  There can be no
assurance, however, that these announced plans will result in increased hardware
or services procurements; increased research and development spending; or that
we would win any contracts funded by any budgetary increases.

  In 1998, 70% of our net sales were made to the U.S. Government, either as a
prime contractor or as a subcontractor.  Accordingly, a substantial portion of
our sales are subject to inherent risks, including uncertainty of economic
conditions, changes in government policies and requirements that may reflect
rapidly changing military and political developments and the availability of
funds.  Other characteristics of the industry are complexity of designs, the
difficulty of forecasting costs and schedules when bidding on developmental and
highly sophisticated technical work, and the rapidity with which product lines
become obsolete due to technological advances and other factors characteristic
of the industry.  Certain risks inherent in the current aerospace and defense
business environment are discussed in "Management's Discussion and Analysis of
Financial Condition and Results of Operations" on page 15 through page 25 of our
1998 Annual Report to Shareholders.



                                      20

     During the past few years, a growing percentage of our business has been in
developmental programs under cost-reimbursement-type contracts, which generally
have lower profit margins than fixed-price-type contracts.  Earnings may vary
materially depending on the types of long-term government contracts undertaken,
the costs incurred in their performance, the achievement of other performance
objectives and the stage of performance at which the right to receive fees,
particularly under incentive and award fee contracts, is finally determined.

  Our international business, which has been growing, tends to have more risk
than our domestic business due to the greater potential for changes in foreign
economic and political environments.  Our business is also highly sensitive to
changes in foreign national priorities and government budgets.  International
transactions frequently involve increased financial and legal risks arising from
stringent contractual terms and conditions and the widely differing legal
systems and customs in foreign countries.

Government Contracts and Regulations

     Our businesses are heavily regulated in most of our markets.  We deal with
numerous U.S. Government agencies and entities, including all of the branches of
the U.S. military and NASA.  Similar government authorities exist in our
international markets.

                                      21
<PAGE>


  The U.S. Government, and other governments, may terminate any of our
government contracts and, in general, subcontracts at their convenience as well
as for default on performance.  If any of our government contracts were to be
terminated for convenience, we generally would be entitled to receive payment
for work completed and allowable termination or cancellation costs.

  Upon termination for convenience of a fixed-price type contract, we normally
are entitled, to the extent of available funding, to receive the purchase price
for delivered items, reimbursement for allowable costs for work-in-process and
an allowance for profit on the contract or adjustment for loss if completion of
performance would have resulted in a loss.  Upon termination for convenience of
a cost-reimbursement type contract, we normally are entitled, to the extent of
available funding, to reimbursement of allowable costs plus a portion of the
fee.  The amount of the fee recovered, if any, is related to the portion of the
work accomplished prior to termination and is determined by negotiation.

  U.S. Government contracts also are conditioned upon the continuing
availability of Congressional appropriations. Long-term government contracts and
related orders are subject to cancellation if appropriations for subsequent
performance periods become unavailable. Congress usually appropriates funds on a
fiscal-year basis even though contract performance may extend over many years.
Consequently, at the outset of a program, the contract is usually partially
funded and Congress annually determines if additional funds are appropriated to
the contract.

  A portion of our business is classified by the government and cannot be
specifically described.  The operating results of these classified programs are
included in our consolidated financial statements.  The business risks

                                      22
<PAGE>

associated with classified programs do not differ materially from those of our
other government programs and products.

Backlog

  At December 31, 1998,  our total negotiated backlog  was $45.3 billion
compared with $47.1 billion at the end of 1997.  The total negotiated backlog of
the sectors at December 31, 1998, was as follows: Space & Strategic Missiles --
$16.1 billion, Electronics -- $10.6 billion, Aeronautics -- $10.6 billion and
Information & Services -- $7.8 billion.  At December 31, 1998, the Energy &
Environment sector contributed almost all of the total negotiated backlog of
$226 million for the reportable business segment of which it is a part, Energy
and Other.  Of our total 1998 year-end backlog, approximately $26.8 billion, or
59.2%, is not expected to be filled within one year.

  These amounts are all approximate and include both unfilled firm orders for
our products for which funding has been both authorized and appropriated by the
customer (Congress in the case of U.S. Government agencies) and firm orders for
which funding has not been appropriated.

Environmental Regulation

  Our operations are subject to and affected by a variety of federal, state and
local environmental protection laws and regulations.  We are involved in
environmental responses at our facilities, former facilities and at third-party
sites not owned by us where we have been designated a "Potentially Responsible
Party" ("PRP") by the U.S. Environmental Protection Agency ("EPA") or by a state
agency.

  At these third-party sites, the EPA or a state agency has identified the site
as requiring remedial action under the federal "Superfund" and other related
federal or state laws governing the remediation of hazardous materials.
Generally, PRPs that are ultimately determined to be "responsible parties" are
strictly liable for site clean-ups and usually agree among themselves to share,
on an allocated basis, in the costs and expenses for investigation and
remediation of the hazardous materials.  Under existing environmental laws,
however, responsible parties are jointly and severally liable and, therefore, we
are potentially liable to government environmental agencies for the full cost of
funding such remediation.  In the unlikely event that we were required to fund
the entire cost of such remediation, the statutory framework provides that we
may pursue rights of contribution from the other PRPs.
 
  At third-party sites, we continue to pursue a course of action designed to
minimize and mitigate our potential liability through assessing the legal basis
for our involvement, including an analysis of such factors as (i) the amount and
nature of materials disposed of by us, (ii) the allocation process, if any, used
to assign costs to all involved parties, and (iii) the scope of the response
action that is or may reasonably be required.  We also continue to pursue active
participation in steering committees, consent orders and other appropriate and
available avenues.  

                                      23
<PAGE>
 
Management believes that this approach should minimize our proportionate share
of liability at third-party sites where other PRPs share liability.
 
  In addition, we manage various government-owned facilities on behalf of the
government. At such facilities, environmental compliance and remediation costs
have historically been the responsibility of the government and we relied (and
continue to rely with respect to past practices) upon government funding to pay
such costs. While the government remains responsible for capital and operating
costs associated with environmental compliance, responsibility for fines and
penalties associated with environmental noncompliance, in certain instances, is
being shifted from the government to the contractor with fines and penalties no
longer constituting allowable costs under the contracts pursuant to which such
facilities are managed.


     Description of Certain Environmental Matters
     --------------------------------------------

     In 1991, we entered into a consent decree with the EPA relating to our
former Lockheed Aeronautical Systems Company facilities in Burbank, California,
which obligated us to design and construct facilities to monitor, extract and
treat groundwater contaminated with chlorinated solvents released from regional
industry, and to operate and maintain such facilities for approximately eight
years.  In 1998, we entered into a follow-on consent decree which obligates us
to fund the continued operation and maintenance of these facilities through the
year 2018. We have also been operating under a cleanup and abatement order from
the California Regional Water Quality Control Board ("Regional Board") relating
to our former Burbank facilities. This order requires site assessment and action
to abate groundwater contamination by a combination of groundwater and soil
cleanup and treatment.  We estimate that total expenditures required over 

                                      24
<PAGE>
 
the remaining terms of the consent decrees and the Regional Board order will be
approximately $110 million.

     We are responding to various administrative orders issued by the Regional
Board in connection with our former Lockheed Propulsion Company facilities in
Redlands, California. Under the orders, we are investigating the impact and
potential remediation of regional groundwater contamination by perchlorates and
chlorinated solvents.  The Regional Board has approved our plan to maintain
public water supplies with respect to chlorinated solvents during this work, and
we are negotiating with local water purveyors to implement this plan, as well as
to address water supply concerns relative to perchlorate contamination. We
estimate that expenditures required to implement work currently approved will be
approximately $110 million. We also are coordinating with the U.S. Air Force,
which is conducting preliminary studies of the potential health effects of
exposure to perchlorates in connection with several sites across the country,
including the Redlands site.  The results of these preliminary studies indicate
that our current efforts with water purveyors regarding perchlorate issues are
appropriate, but it is not yet possible to project the extent of our ultimate
perchlorates clean-up obligation, if any.

          Under an agreement with the U.S. Government, the Burbank groundwater
treatment and soil remediation expenditures referenced above are being allocated
to our operations as general and administrative costs and, under existing
government regulations, these and other environmental expenditures related to
U.S. Government business, after deducting any recoveries from insurance or other
PRPs, are allowable in establishing the prices of our products and services.  As
a result, a substantial portion of the expenditures are being reflected in our
sales and cost of sales pursuant to U.S. Government agreement or regulation.
Although the Defense 

                                      25
<PAGE>
 
Contract Audit Agency has questioned certain elements of our practices with
respect to the agreement with the U.S. Government, no formal action has been
initiated, and it is management's opinion that the treatment of these
environmental costs is appropriate and consistent with the terms of such
agreement. We have recorded an asset for the portion of environmental costs that
are probable of future recovery in the pricing of our products and services for
U.S. Government business. The portion that is expected to be allocated to
commercial business has been reflected in the cost of sales. The recorded
amounts do not reflect the possible future recovery of portions of the
environmental costs through insurance policy coverage or from other PRPs, which
we are pursuing as required by agreement and U.S. Government regulation. Any
such recoveries, when received, would reduce our liability as well as the
allocated amounts to be included in our U.S. Government sales and cost of sales.

     The extent of the our financial exposure relating to environmental matters
cannot in all cases be reasonably estimated at this time.  A liability of
approximately $460 million, including the aggregate $220 million estimate for
matters related to our former Redlands and Burbank facilities noted above, for
those cases in which an estimate of financial exposure can be determined has
been recorded.  Because of the regulatory complexities and risk of unidentified
contaminated sites and circumstances, the potential exists for environmental
remediation costs to be materially different from the estimated costs accrued
for identified contaminated sites.  In addition, our involvement and extent of
responsibility varies at each site.  After an assessment of each site and
consultation with environmental experts and counsel, management has concluded
that the probability is remote that our actual or potential liability as a PRP
in each or all of these sites, in combination with our actual or potential
liability for environmental responses at our own facilities or in our contract
management capacity at government-owned facilities, will have a material 


                                      26
<PAGE>
 
adverse effect on our consolidated results of operations or financial position.

"Notes to Consolidated Financial Statements" on page 42 through page 43 and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations, Environmental Matters" on page 24 through page 25 of the 1998 Annual
Report to Shareholders.
 
Research and Development

  We conduct research and development activities under customer contract funding
and with Independent Research and Development ("IR&D") funds.  IR&D efforts
consist of projects involving basic research, applied research, development, and
systems and other concept formulation studies.  In 1998, we spent approximately
$1.1 billion of IR&D and bid and proposal funds, a substantial portion of which
was included in general and administrative costs allocable to U.S. Government
contracts.

  During 1998,  we did not undertake the development of a new product or line of
business requiring the investment of a material amount of our total assets.
Effective January 1999, we transferred certain businesses to LMGT.  Our launch
services business, however, is requiring increasing investments in the
development or improvement of launch vehicles.

  See "Research and development and similar costs" in "Note 1-- Summary of
Significant Accounting Policies" of the "Notes to Consolidated Financial
Statements" on page 33 of the 1998 Annual Report to Shareholders.


Employees

  At December 31, 1998, we had approximately 165,000 employees, the majority of
whom 

                                      27
<PAGE>
 
were located in the United States. We have a continuing need for numerous
skilled and professional personnel to meet contract schedules and obtain new and
ongoing orders for our products. Approximately one-fifth of our employees are
covered by over a hundred separate collective bargaining agreements with various
international and local unions. Management considers employee relations
generally to be good.

ITEM 2. PROPERTIES

  At December 31, 1998, we operated in 445 offices, facilities, manufacturing
plants, 

                                      29
<PAGE>
 
warehouses, service centers and laboratories throughout the United States and
internationally. Of these, we owned floor space at 64 locations aggregating
approximately 41.4 million square feet and we leased space at 381 locations
aggregating approximately 24.9 million square feet. At December 31, 1998, we
managed and/or occupied various major government-owned facilities The U.S.
Government also furnishes certain equipment used by us.

large tracts include:

  A portion of our activity is related to engineering and research and
development, which is not susceptible to productive capacity analysis.  In the
area of manufacturing, most of the operations are of a job-order nature, rather
than an assembly line process, and productive equipment has multiple uses for
multiple products.  Management believes that all of our major physical
facilities are in good condition and are adequate for their intended use.

ITEM 3.  LEGAL PROCEEDINGS

  We are parties or have property subject to litigation and other proceedings,
including matters arising under provisions relating to the protection of the
environment, both as specifically

described below or arising in the ordinary course of our business. In the
opinion of management, the probability is remote that the outcome of any such
litigation or other proceedings, will have a material adverse effect on our
results of operations or financial position.

  We are primarily engaged in providing products and services under contracts
with the U.S. Government and, to a lesser degree, under direct foreign sales
contracts, some of which are funded by the U.S. Government.  These contracts are
subject to extensive legal and regulatory requirements and, from time to time,
agencies of the U.S. Government investigate whether our operations are being
conducted in accordance with these requirements.  U.S. Government investigations
of us, whether relating to these contracts or conducted for other reasons, could
result in administrative, civil or criminal liabilities, including repayments,
fines or penalties being imposed upon us, or could lead to suspension or
debarment from future U.S. Government contracting.  U.S. Government
investigations often take years to complete and many result in no adverse action
against us.  For the U.S. government investigations noted below, it is too early
for us to determine whether adverse decisions relating to these investigations
could ultimately have a material adverse effect on our results of operations or
financial condition.


  New Matters
  -----------

  On January 14, 1999, Mohammad Yousefi and David Kane filed a lawsuit against
us and six of our officers and directors (Vance D. Coffman, Marcus C. Bennett,
James A. Blackwell, Jr., Thomas A. Corcoran, Vincent N. Marafino and Norman R.
Augustine)("Yousefi complaint").  The complaint contains class action
allegations and states that it is filed on behalf of the named plaintiffs as
well as on behalf of purchasers of  our common stock  between August 13, 1998
and December 23, 1998.  The complaint alleges that the defendants violated
Sections 10(b) and 20(a) 

                                      32
<PAGE>
 
of the Securities Exchange Act of 1934 in that they or persons they controlled
allegedly (a) employed devices, schemes and artifices to defraud; (b) made
untrue statements of material facts or omitted to state material facts necessary
in order to make statements made, in light of the circumstances under which they
were made, not misleading; or (c) engaged in acts, practices and a course of
business that operated as a fraud or deceit upon class members in connection
with their purchases of our common stock. The complaint further alleges that the
statutory safe harbor provided for forward-looking statements does not apply to
any of the allegedly false forward-looking statements. According to the
complaint, class members were damaged as, in reliance on the integrity of the
market, they paid artificially inflated prices for our stock. Plaintiffs seek a
judgment awarding (a) damages and costs; (b) equitable or injunctive relief,
including the imposition of a constructive trust upon defendants' alleged
insider-trading proceeds; and (c) other just and proper relief. We believe that
the allegations are without merit and will defend this and any related actions.

  As is common with private securities class action litigation, we and the same
persons in the Yousefi complaint, have been named as defendants in additional,
multiple actions purportedly brought on behalf of our shareholders, which were
filed subsequent to the Yousefi complaint.  These additional actions assert
substantially the same claims made in the Yousefi complaint.  We anticipate that
additional related actions could be filed.  We also expect that the multiple
actions will be consolidated and that the court will appoint as lead plaintiff
the member or members of the purported plaintiff class that the court determines
to be most capable of adequately representing the interests of class members.

     Previously Reported Matters
     ----------------------------

  In 1994, the DOE awarded our subsidiary, Lockheed Martin Advanced
Environmental Systems, Inc. ("LMAES"), a $180 million fixed price contract at
the Idaho National Engineering and Environmental Laboratory ("INEEL") for the
Phase II design, construction and limited test of remediation facilities and the
Phase III full remediation of waste found in Pit 9, located on the INEEL
reservation.  At the time the contract was definitized, Lockheed Martin Idaho
Technologies Company ("LMITCO"), another of our subsidiaries, was the INEEL
management contractor.

  As we performed under the contract, we incurred unanticipated costs and
scheduling issues due to complex technical and contractual matters which
threatened the viability of the overall Pit 9 program.  On March 31, 1997, based
on an investigation by management to identify and quantify the overall effect of
these matters, we submitted a request for equitable adjustment ("REA") to the
DOE that sought, among other things, the recovery of a portion of unanticipated
costs incurred by us.  We also sought to restructure the contract to provide for
a more equitable sharing of the risks associated with the Pit 9 project. We were
unsuccessful in reaching any agreements with the DOE on cost recovery or other
contract restructuring matters. Starting in May 1997, we reduced work activities
at the Pit 9 site while awaiting technical direction from the DOE.

  On June 1, 1998, the DOE directed LMITCO to terminate the Pit 9 contract for
default. On that same date, we filed a lawsuit against the DOE in the U.S. Court
of Federal Claims in Washington, D.C., challenging and seeking to overturn the
default termination. In addition, on July 21, 1998, we withdrew the REA
previously submitted to the DOE in March 1997 and
                                      34
<PAGE>
 
replaced it with a certified REA. The certified REA is similar in substance to
the REA previously submitted, but its certification, based upon more detailed
factual and contractual analysis, raises its status to that of a formal claim.
On August 11, 1998, LMITCO, at the DOE's direction, filed suit against us in
U.S. District Court in Idaho, seeking recovery of approximately $54 million
previously paid by LMITCO to us under the Pit 9 contract. We intend to defend
this action while continuing to pursue our certified REA. On January 26, 1999,
the U.S. District Court in Idaho granted our motion and stayed the Idaho
proceeding until resolution of the motion to dismiss our lawsuit in the Court of
Federal Claims, or until August 2, 1999. We continue to assert our position in
the litigation while continuing our efforts to resolve the dispute through non-
litigation means.

  Since July 1995, we have been served with grand jury subpoenas issued by the
U.S. District Court for the Eastern District of New York seeking documents
related to the performance of various government contracts by the former Unisys
Corporation Defense Systems facility at Great Neck, New York.  We acquired the
facility when we acquired Loral Corporation in April 1996.  Loral Corporation
acquired the facility from Unisys Corporation.  We are cooperating with the U.S.
Government's continuing investigation of this matter.

  We have been served, along with various of our current and former employees,
with grand jury subpoenas issued by the U.S. District Court for the Middle
District of Florida and subpoenas issued by the Department of Defense Inspector
General relating to the LANTIRN program.  The U.S. Attorney's Office for the
Middle District of Florida has advised us that the grand jury is investigating
allegations of fraud in connection with certain LANTIRN program contracts.
These allegations, in part, were first made in qui tam complaints filed against
us and 

                                      35
<PAGE>
 
unsealed on July 16, 1996. We are cooperating with the U.S. Government's
continuing investigation of this matter.
 
  Lockheed Martin Technical Operations Company, our wholly-owned subsidiary, and
certain of its current and former employees were served with grand jury
subpoenas issued by the United States District Court for the District of
Colorado seeking documents relating to efforts to obtain and to perform a
contract with the U.S. Air Force for space operations, maintenance and support
services.  We are cooperating with the U.S. Government's continuing
investigation of this matter.

  We understand that the U.S. Government's investigations have been closed
relating to (i) former employees of our Armament Systems business in Milan,
Tennessee and (ii) procurement of parking meter and other services by the
District of Columbia from Lockheed Martin IMS Corporation.

  We are a party to or have our property subject to various other litigation and
proceedings involving matters arising under provisions relating to the
protection of the environment. We are subject to federal and state requirements
for protection of the environment, including those for discharge of hazardous
materials and remediation of contaminated sites.  Due in part to their
complexity and pervasiveness, such requirements have resulted in us being
involved with related legal proceedings, claims and remediation obligations.
For a discussion of these matters, see "Item 1. Business  Environmental
Regulation."


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

  No matters were submitted to a vote of security holders during the fourth
quarter of 1998.

                               DEFERRAL ACCOUNTS

     4.1. Stock Unit Account.

     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, provided that the Board of
Directors previously approved the Award. A Director who is not serving as a
director on an Award Date is not eligible for any portion of the 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.

     The rights of each Director in respect of his or her Stock Unit Account and
related Dividend Equivalent Stock Account shall vest immediately on crediting.

     4.4. Distribution of Benefits.

     (a)  Commencement of Benefits Distribution.  Subject to the terms of this
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.  Benefits shall be
distributed at the time or times set forth in Section 4.4.

     (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 
<PAGE>
 
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. Subject to
Section 4.4(f), 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.  In the event of
a termination of service or retirement, a Director may elect, in accordance with
the provisions of Section 4.4(f), to have Stock Units credited to the Director's
Stock Unit Account and Dividend Share Equivalent Account paid and distributed in
the form of cash or a combination of whole shares of Common Stock and cash.  Any
such election shall be made at times and in the manner specified in Section
4.4(f).

     (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 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).
In addition, in the event of a termination of service or retirement, at least
six months prior to receipt by a Director of any distribution of benefits under
the Plan, the Director shall make a written election (on forms to be provided by
the Corporation) as to the percentage the Director elects to receive in the form
of cash and the percentage the Director elects to receive in the form of whole
shares of Common Stock.

     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 
<PAGE>
 
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, although the Corporation shall reserve
shares of Common Stock 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.

Exchange Act. Notwithstanding the foregoing, but subject to Section 6.1 hereof,

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.

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.

Effective Date, but continuance of this Plan is not assumed as a contractual
obligation of the Corporation.  Effective May 1, 1999, the Plan is frozen.
Other than Dividend Equivalents relating to Units credited to Directors' Stock
Unit Accounts prior to May 1, 1999, no further Awards shall be made under this
Plan on or after May 1, 1999.  Benefits under the Plan shall continue to be paid

                                 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.

of general unsecured creditors of the Corporation with respect to amounts
credited or vested and benefits payable, if any, on their Accounts.

     7.2. Beneficiaries.

     (a)  Beneficiary Designation.  Upon forms provided and in accordance with

payable under this Plan after his or her death, subject to applicable laws
(including any applicable community property and probate laws).

     (b)  Definition of Beneficiary.  A Director's "Beneficiary" or
"Beneficiaries" shall be the person or persons, including a trust or trusts,

Director's benefits under this Plan in the event of the Director's death.

unenforceable, the remaining provisions hereof shall continue to be fully
effective.

                                 PARTICIPATION

     3.1  Timing of Deferral Elections.  In order to defer Director's fees
earned in any calendar year, a Director must make a deferral election by
executing and filing an Election Form before the commencement of that calendar
year or, in the case of a new Director, before the commencement of the
Director's term of office in that calendar year.  The deferral election shall
specify the manner in which earnings (or losses) on the deferred amount shall
accrue in accordance with Section 4.2 below.  To the extent that a Director
elects that any portion of a deferred amount shall accrue earnings based on the
Lockheed Martin Common Stock Investment Option, such an election shall be given
effect only if (i) the election is irrevocably made at least six (6) months
prior to the effective date of the allocation or (ii) the crediting of the
deferred amount to the Lockheed Martin Common Stock Investment Option has been
approved by the Board of Directors (or a committee thereof that is comprised of
persons specified in Section 6.1).  To the extent that a Director makes an
election to have Deferred Compensation credited to the Lockheed Martin Common
Stock Investment Option which is not in compliance with (i) or (ii) above, the
amount elected to be deferred into the Lockheed Martin Common Stock Investment
Option shall initially be allocated to the Interest Option until such time as
the allocation to the 
<PAGE>
 
Lockheed Martin Common Stock Investment Option would be in compliance with (i)
or (ii) above, at which time the deferred amount shall automatically be
reallocated.

     3.2  Terms of Deferral Elections.  A Director's deferral election for a
calendar year shall specify the percentage (which may equal 100%) of the
Director's Fees to be earned by the Director for that year which are to be
deferred under this Plan.  A Director's deferral election shall remain in effect
for each subsequent calendar year, unless the Director duly files a revised
Election Form or written revocation of the election before the beginning of the
subsequent calendar year.  A Director's deferral election shall be irrevocable
during any calendar year in which it is in effect.

                                  ARTICLE IV

                             CREDITING OF ACCOUNTS

     4.1  Crediting of Director's Fees.  Director's Fees that a Director has
elected to defer shall be credited to the Director's Account as of the first day
of the month in which the Director's Fees would have been payable to the
Director if no deferral election had been made under this Plan.  The elected
deferral percentage shall apply to all Director's Fees earned by the Director
during a calendar year.

     4.2  Crediting of Investment Earnings.  Subject to the provisions of
Section 3.1 above, as of the last day of each month, a Director's Account shall
be credited to reflect investment earnings (or loss) for the month, based on the
Director's investment selections under this Section 4.2.  A Director may elect
to have his or her Account credited with investment earnings (or losses) for
each month as if the Director's Account balance had been invested in the
following:

     (a)  Interest Option. Interest at a rate equal to one twelfth (1/12) of the
annual prime rate as set by Citibank, N.A., New York, New York, on the last day
of the preceding month.,

     (b)  S&P 500 Option.  A return (or loss) equal to that of the published
index for the Standard & Poors 500 (with dividends) for the month will accrue.

     (c)  Lockheed Martin Common Stock Investment Option.  Earnings (or losses)
shall be credited as if such amount had been invested in Lockheed Martin Common
Stock at the published closing price of the Corporation's Common Stock on the
New York Stock Exchange on the last trading day preceding the day as to which
such amount is deferred (or reallocated) into the Lockheed Martin Common Stock
Investment Option; this portion of a Director's Account shall reflect any
subsequent appreciation or depreciation in the market value of Lockheed Martin
Common Stock based on the published closing price of the stock on the New York
Stock Exchange on the last trading day of each month and shall reflect dividends
on the stock as if such dividends were reinvested in shares of Lockheed Martin
Common Stock.

     (d)  A combination of (a), (b) and (c).
<PAGE>
 
A Director's initial investment selections must be made by the date that the
Director's initial deferral election takes effect.  A Director may change his or
her investment selections with respect to all amounts credited to the Director's
Account, including amounts deferred in prior periods, provided that any such
change that would result in an increase or decrease in the portion of the
Director's Account allocated to the Lockheed Martin Common Stock Investment
Option shall only be effective if it is made pursuant to an irrevocable written
election made at least six months following the date of the Director's most
recent "opposite way" election with respect to either the Plan or any other plan
maintained by Lockheed Martin that provides for Discretionary Transactions (as
defined in Rule 16b-3).  Subject to the foregoing, a change of investment
selections must be made by filing a revised Election Form in advance of the
month in which the change is to take effect.

     4.3  Account Balance as Measure of Deferred Compensation.  The Deferred
Compensation payable to a Director (or the Director's Beneficiary) shall be
measured by, and shall in no event exceed, the sum of the amounts credited to
the Director's Account.

                                   ARTICLE V

                       PAYMENT OF DEFERRED COMPENSATION

     5.1  Manner of Distribution.

     (a)  Lump sum payments.  Subject to the provisions of Section 5.6, a
Director's Deferred Compensation shall be paid as a lump sum cash payment equal
to the balance credited to the Director's Account on the December 31 that is
coincident with or next follows the date of the termination of the Director's
status as a Director, unless the Director has elected to receive installment
payments in accordance with Section 5.1(b).

     (b)  Installment payments.  A Director may elect to have the Director's
Deferred Compensation distributed in annual installments over a maximum period
of ten (10) years.  The amount of each annual installment shall be determined by
dividing the Director's Account balance (or the portion of the Account balance
to which the installment election applies) on the December 31 preceding the
payment date by the number of years remaining in the elected installment period.
A Director's election to receive installment payments with respect to Director's
fees deferred in any calendar year must be made on an Election Form duly filed
no later than the latest date on which a deferral election may be made for that
calendar year under Section 4.1.  A Director's installment election shall remain
in effect with respect to Director's fees deferred in each subsequent calendar
year, unless the Director duly files a revised Election Form before the
beginning of the subsequent calendar year.  An installment election shall be
irrevocable with respect to Director's fees deferred (and allocable investment
earnings) in any calendar year for which the installment election is in effect.

     (c)  Deferral For Directors Fees Earned in 1996.  A Director may elect to
have the Director's Deferred Compensation earned during the 1996 calendar year
credited and paid as a lump sum under (a) or annual installments under (b)
except that payment (or installments, as the 
<PAGE>
 
case may be) will be made (or commence) on January 1, 1998, or as soon as
practicable thereafter regardless of whether the Director has terminated service
as a Director.

     5.2  Commencement of Payments.  Subject to the provisions of Section 5.6
and except as provided in Sections 5.1(c) and 5.4, the payment of Deferred
Compensation to a Director shall be made or commence in January of the first
calendar year following the year in which the Director ceases to be a Director,
whether due to resignation, retirement, disability, death, or otherwise.
Installment payments shall continue to be made in January of each succeeding
year until all installments have been paid.

     5.3  Death Benefits.  Subject to the provisions of Section 5.6, in the
event that a Director dies before payment of the Director's Deferred
Compensation has commenced or been completed, the balance of the Director's
Account shall be distributed to the Director's Beneficiary commencing in the
January following the date of the Director's death in accordance with the manner
of distribution (lump sum or annual installments) elected by the Director for
payments during the Director's lifetime.  However, upon good cause shown by a
Beneficiary or personal representative of the Director, the Committee, in its
sole discretion, may reject a Director's installment election and instead cause
the Director's death benefits to be paid in a lump sum.

     5.4  Emergency Withdrawals.  In the event of an unforeseeable emergency
prior to the commencement of distributions or after the commencement of
installment payments, the Committee may approve a distribution to a Director (or
Beneficiary after the death of a Director) of the part of the Director's Account
balance that is reasonably needed to satisfy the emergency need.  An Emergency
withdrawal will be approved only in a circumstance of severe financial hardship
to the Director (or Beneficiary after the death of the Director) resulting from
a sudden and unexpected illness or accident of the Director (or Beneficiary, as
applicable) or of a dependent of the Director (or Beneficiary, as applicable),
loss of property due to casualty, or other similar extraordinary or
unforeseeable circumstance arising from events beyond the control of the

withdrawal occurs.

     Status of Certain Directors.

     (a)  For purposes of Section 5.2, a retired Director who continues to
advise the Board of Directors under an Advisory Services Agreement shall be
treated as an active Director for the period that he or she continues to serve
under such agreement, if the Director so elects on or before April 25, 1996. An
election under this Section 5.5 shall not otherwise alter the Director's rights
under this plan. Once made, an election under this Section 5.5 shall be
irrevocable.

     (b)  For the purposes of Article VI, a member of the Board of Directors who

Retirement Benefit shall be eligible to defer such compensation pursuant to this
Plan.

     5.6  Corporation's Right to Withhold.  There shall be deducted from all

under applicable federal or state tax laws.  The Directors and their
Beneficiaries will be liable for payment of any and all income or other taxes
imposed on Deferred Compensation payable under this Plan.

contained herein to the contrary, no distribution of any portion of a Director's
Account credited to the Lockheed Martin Common Stock Investment Option shall be

distribution or (ii) at least six months have passed from the date the
Director's service on the Board has terminated.

Retirement Benefit in a single lump sum payable on or about May 1, 2000 so long
as prior to May 1, 1999, the Director makes an irrevocable written  election to
receive the lump sum payment.  Any lump sum payment made pursuant to this
Section 6.2 shall include amounts credited as investment earnings with respect
to the Lump Sum Retirement Benefit for the period from May 1, 1999 until April
30, 2000.  Notwithstanding anything herein to the contrary, no portion of a

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

of general unsecured creditors of the Corporation with respect to amounts
credited to or payable from their Accounts.

become payable after the Director's death, as provided in Section 5.3.  A
Director's Beneficiary designation shall be made on forms provided and in
accordance with procedures established by the Corporation and may be changed by
the Director at any time before the Director's death.

     (b)  Definition of Beneficiary.  A Director's "Beneficiary" or
"Beneficiaries" shall be the person or persons, including a trust or trusts,
validly designated by the Director or, in the absence of a valid designation,
entitled by will or the laws of descent and distribution to receive the amounts
otherwise payable to the Director under this Plan in the event of the Director's
death.

     8.3  Rights Not Assignable; Obligations Binding Upon Successors.  A
Director's rights under this Plan shall not be assignable or transferable and
any purported transfer, assignment, pledge or other encumbrance or attachment of
any payments or benefits under this Plan, or any interest thereon, other than
pursuant to Section 7.2, shall not be permitted or recognized.  Obligations of
the Corporation under this Plan shall be binding upon successors of the
Corporation.

     8.4  Governing Law; Severability.  The validity of this Plan or any of its
provisions shall be construed, administered, and governed in all respects under

effective.

Director shall be deemed conclusively to have accepted and consented to all of
the terms of this Plan and to all actions and decisions of the Corporation,

          The purpose of this Plan is to provide retirement income to persons

judgment can contribute to the success of the Corporation.

                                  ARTICLE II

                                  DEFINITIONS

contrary:

          BENEFICIARY shall have the meaning specified in Section 6.2(b).

          BOARD OF DIRECTORS or BOARD means the Board of Directors of the
Corporation.

          COMMITTEE means the Committee appointed to administer this Plan, as
provided in Section 5.1 hereof.

          CORPORATION means Lockheed Martin Corporation, a Maryland corporation
and its successors.

          DIRECTOR means a member of the Board of Directors of the Corporation
who is eligible to receive compensation in the form of Retainer Fees and who is
not an officer or employee of the Corporation or any of its subsidiaries; where
indicated by the context, the term Director shall include a retired or former
Director.

          PLAN means the Lockheed Martin Corporation Directors Retirement Plan.

          RETAINER FEE means the annual fee payable to a Director for service as
a Board member, including the value of the amount annually credited to each
Director under the Lockheed Martin Corporation Directors Deferred Stock Plan,
but not including any fees for services as a member of a committee of the Board.
<PAGE>
 
          RETIREMENT AGE means the age for mandatory retirement of Directors
from Board membership, as specified in the Corporation's by-laws on the date a
Director retires, resigns, or otherwise ceases to be a member of the Board.


                                  ARTICLE III

                           ELIGIBILITY FOR BENEFITS

          3.1  FIVE-YEAR SERVICE REQUIREMENT.  Except as provided in Sections
4.1 and 4.6, a Director shall be eligible to receive benefits under this Plan
only if the Director has served as a member of the Board for five (5) or more
years, and the Director retires, resigns, or otherwise ceases to be a member of
the Board after the Effective Date.

          3.2  CREDITED SERVICE.  For purposes of Section 3.1 and Article IV, a
Director's years of service as a Board member shall be deemed to include all
periods in which he or she served as a director of the Corporation, Lockheed
Corporation, or Martin Marietta Corporation, including all periods in which he
or she served as a director while an employee of one or more of those
corporations.  A Director shall be credited with a year of service for each
twelve (12) month period of Board service; fractional years of service shall not
be taken into account under this Plan.


                                  ARTICLE IV

                                   BENEFITS

          4.1  RETIREMENT AT RETIREMENT AGE.  If a Director retires from the
Board on or after attainment of Retirement Age, the Corporation shall make
annual payments to the Director in the amount of the Retainer Fee for life.
Such payments shall commence in the January following the year in which the
Director retires and shall be made in each successive January ending with the
January payment for the calendar year of the Director's death.  Upon the
approval of the Nominating Committee of the Board, a Director who retires from
the Board on or after attainment of Retirement Age, but with less than five (5)
years of service on the Board, may be treated as having satisfied the
eligibility requirement of Section 3.1.  Notwithstanding the foregoing, an
initial payment prorated to reflect the number of months remaining in the year
shall be made to the Director as soon as practicable following his retirement.

          4.2  RESIGNATION BEFORE RETIREMENT AGE.  If a Director retires,
resigns, or otherwise ceases to be a member of the Board before attaining
Retirement Age, the Corporation shall make annual payments to the Director in
the amount of the Retainer Fee for a number of years equal to the number of full
years the Director had served on the Board.  Such payments shall commence in the
January following the year in which the Director ceases to be a member of the
Board and shall be made in each successive January until the payments have been
completed.

          4.3  DEATH BENEFITS.  Upon the death of an active Director, whether or
not such Director has served as a Director for five (5) years, or a retired or
former Director entitled to benefits under Section 4.1 or 4.2, the Corporation
shall make annual payments to the Director's Beneficiary in the amount of the
Retainer Fee for a number of years equal to (i) the number of full years the
Director had served on the Board, less (ii) the number of years, if any, for
which payments were made to the Director under Section 4.1 or 4.2, provided that
the number of annual payments to a Director's Beneficiary shall in no event
exceed twenty (20).  Such payments shall commence in the January following the
year of the Director's death and shall be made in each successive January until
the payments have been completed.

          4.4  RETAINER FEE USED TO DETERMINE BENEFITS.  All benefits payable to
or with respect to a Director shall be based upon the amount of the Retainer Fee
in effect on the Date the Director retires, resigns, or otherwise ceases to be a
member of the Board.
<PAGE>
 
          4.5  COORDINATION WITH PREDECESSOR PLANS.  The payments to a Director
or Beneficiary under Section 4.1, 4.2, or 4.3 shall be adjusted to reflect
payments made or to be made under the Post-Retirement Income Maintenance Plan
for Directors of Martin Marietta Corporation (the "Martin Marietta Plan") and
the Lockheed Corporation Retirement Plan for Directors (the "Lockheed Plan") in
the following manner:

          (a)  With respect to any Director who received a lump sum payment
under the Martin Marietta Plan, each annual benefit payment under this Plan
(commencing with the earliest year in which a benefit is otherwise payable)
shall be reduced by an amount equal to the annual retainer fee that was taken
into account in determining the amount of the lump sum payment to the Director
under the Martin Plan; that reduction shall be made for a number of years equal
to the number of years of accrued benefits for which the Director received the
lump sum payment under the Martin Plan; thereafter, any benefits payable to the
Director or the Director's Beneficiary under this Plan shall be unaffected by
this Section 4.5.

          (b)  With respect to any Director who has accrued the right to receive
benefits under the Lockheed Plan and who has not waived that right in favor of
the benefits payable under this Plan:

               (i)    the amount of any annual benefit payment that would be
          made to the Director or the Director's Beneficiary under this Plan in
          January of a year shall be reduced by the sum of the monthly benefit
          payments, if any, made to the Director or the Director's surviving
          spouse under the Lockheed Plan in the preceding calendar year;

               (ii)   if a lump sum payment has been made to the Director or the
          Director's surviving spouse under the Lockheed Plan, each annual
          benefit payment under this Plan (commencing with the earliest year in
          which a benefit is otherwise payable) shall be reduced by an amount
          equal to the annual retainer fee that was taken into account in
          determining the amount of the lump sum payment under the Lockheed
          Plan; that reduction shall be made for the number of years equal to
          the number of years of accrued benefits for which the lump sum payment
          was made under the Lockheed Plan; thereafter, any benefits payable to
          the Director or the Director's Beneficiary under this Plan shall be
          unaffected by this Section 4.5; and

               (iii)  if the benefit payments to the Director or the Director's
          surviving spouse under the Lockheed Plan will commence later than the
          date on which benefit payments would otherwise commence to be made to
          the Director or the Director's Beneficiary under this Plan, payments
          under this Plan shall commence no earlier than January of the calendar
          year following the year in which benefit payments will commence under
          the Lockheed Plan, advanced by one year for each full year that the
          Director has served on the Board of the Corporation (excluding years
          of service as a director of Lockheed Corporation).

          4.6  PROVISIONS FOR DIRECTORS RETIRING DURING APRIL, 1996.
Notwithstanding any other provision of the Plan to the contrary, a Director who
retires from the Board during April, 1996 shall receive annual payments for life
in accordance with Section 4.1, regardless of whether the Director has served
five years on the Board and regardless of whether the Director has attained age
70 at the time of retirement.  The amount of the annual payment shall equal the
amount of the Annual Retainer in effect at the time of the Director's retirement
as set forth in Section 4.4, except that the annual amount shall be increased
from time to time to reflect any increases made in the Annual Retainer payable
with respect to Directors on or before the end of the year in which the retired
Director attains age 70.

                                   ARTICLE V

                   ADMINISTRATION, AMENDMENT AND TERMINATION

          5.1  ADMINISTRATION BY COMMITTEE.  This Plan shall be administered by
a Committee of three consisting of the (i) Chief Financial Officer of the
Corporation, (ii) Secretary of the Corporation, and (iii) Treasurer of the
Corporation.  The Committee shall act by vote or by written consent of a
majority of its members.  The Committee's resolution of any question regarding
the interpretation of this Plan shall be subject to review by the Board, and the
Board's determination shall be final and binding on all parties.

          5.2  AMENDMENT AND TERMINATION.  This Plan may be amended, modified,
or terminated by the Board at any time, except that no such action shall
(without the consent of affected Directors or, if appropriate, their
Beneficiaries or personal representatives) adversely affect the rights of
Directors or Beneficiaries with respect to benefit rights accrued under this
Plan prior to the date of such amendment, modification, or termination.

     (a)  Effective May 1, 1999, the Plan is terminated with respect to any
Director who is not receiving benefits under the Plan at that time and no
further benefits will be paid under the Plan for such Directors (or their
Beneficiaries).  Benefits shall continue to be payable in accordance with the
terms of the Plan as in effect prior to May 1, 1999 for any Director or
Beneficiary who is receiving benefits under the Plan on that date.

(b) The Committee shall determine the present value of the benefit rights
accrued under the Plan by each Active Director as of May 1, 1999 and the amount
determined by the Committee for each Active Director shall be credited to that
Active Director's Account in the Lockheed Martin Corporation Deferred
Compensation Plan for Directors as of that date.   For the purposes of this
Section 5.2, an Active Director is any Director who has not retired prior to
April 1, 1999 including any Director who is an officer or employee of the
Corporation at that time.

     (c)  The Committee shall determine the benefit rights accrued by each
Active Director based on the payments the Active Director would have received
following the Active Director's retirement under Section 4.1 of the Plan, had
the Plan not been terminated; provided however that the Committee shall provide
each such Director with an opportunity to elect whether the benefit rights
accrued by the Active Director under the Plan shall be calculated by using the
anticipated payments that would be made to the Director based (i) solely on the
Director's whole years of service under the Plan, assuming the Director
continued as a Director until retirement age; or (ii) solely on his or her life
expectancy at retirement age. In either case, the determination shall be subject
to the reduction required by Section 4.5(a) of the Plan and a reduction of
$13,000 (determined on a present value basis) for each projected year of service
after 1998.  In addition, for the purposes of determining the Director's benefit
rights, the Retainer Fee will be assumed to increase at a rate of 3% per year.

     (d)  In determining the present value of the benefit rights accrued under
the Plan as determined under paragraph (c), a discount rate of 8.5% will be used
for the period prior to the date on which the Active Director would otherwise be
eligible to retire under the Plan and a discount rate of 5.1% shall be used for
periods after the date on which the Active Director would otherwise be eligible
to retire.

          6.1  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

any applicable community property and probate laws), each Director may designate
in writing the Beneficiary that the Director chooses to receive any payments
that become payable after the Director's death, as provided in Section 4.3.  A
Director's Beneficiary designation shall be made on forms provided and in
accordance with procedures established by the Corporation and may be changed by
the Director at any time before the Director's death.

          (b)  DEFINITION OF BENEFICIARY.  A Director's "Beneficiary" or
"Beneficiaries" shall be the person or persons, including a trust or trusts,
validly designated by the Director or, in the absence of a valid designation,
entitled by will or the laws of descent and distribution to receive the amounts
otherwise payable to the Director under this Plan in the event of the Director's
death.

          6.3  RIGHTS NOT ASSIGNABLE; OBLIGATIONS BINDING UPON SUCCESSORS.  A
Director's rights under this Plan shall not be assignable or transferable and
any purported transfer, assignment, pledge or other encumbrance or attachment of
any payments or benefits under this Plan, or any interest thereon, other than
pursuant to Section 6.2, shall not be permitted or recognized.  Obligations of
the Corporation under this Plan shall be binding upon successors of the
Corporation.

          6.4  GOVERNING LAW; SEVERABILITY.  The validity of this Plan or any of
its provisions shall be construed, administered, and governed in all respects

instrument shall be held by a court of competent jurisdiction to be invalid or
unenforceable, the remaining provisions hereof shall continue to be fully
effective.

          6.5  CORPORATION'S RIGHT TO WITHHOLD.  There shall be deducted from
all payments under this Plan the amount of taxes, if any, required to be
withheld under applicable federal or state tax laws.  The Directors and their

a termination of service.  The Dividend Equivalents shall be credited to the

below.

          (b)  Dividend Equivalent Stock Account.  The Director's Dividend

forfeited.  Notwithstanding the provisions of this Section 4.3, all nonvested
Units and related Dividend Equivalents granted to a Director shall vest upon a
Change in Control or in the event of such Director's Retirement, death or
Disability.

     4.4. Distribution of Benefits.

          (a)  Commencement of Benefits Distribution.  Subject to the terms of
Section 4.3 and this 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.
Benefits shall be distributed at the time or times set forth in this Section
4.4.

          (b)  Manner of Distribution.  The benefits payable under this Section
shall be distributed to the Director in a lump sum, unless the Director elects
in writing (on forms provided by the Corporation) on or before the Award Date on
which the Units are granted to receive a distribution of benefits in
approximately equal annual installments for  up to ten years.  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.  Installment payments shall commence as of the date the
Accounts become distributable under Section 4.4(a).  The amount of each
installment shall be equal to (i) the Fair Market Value of the Units allocated
to Director's Stock Unit Account and Dividend Equivalent Account, on the day
immediately preceding the date of payment, divided by (ii) the number of
installments yet to be paid.  Notwithstanding the foregoing, if the vested
balance remaining in a Director's Stock Unit Account and Dividend Equivalent
Stock Account is less than 50 Units, then the remaining balance shall be
distributed in a lump sum in the form of cash or Stock, as previously elected by
the Director.  In the event of a Change in Control or a Director's termination
of services as a result of death or Disability, either prior to or after the
Director has terminated service, the benefits payable under this Section shall
be distributed in a lump sum in cash.

          (c)  Form of Distribution.  Stock Units shall be paid and distributed
by means of a distribution of (i) an equivalent whole number of shares of Common
Stock or (ii) cash in an amount equal to the Fair Market Value of an equivalent
number of shares of Common Stock as of the business day immediately preceding
the distribution.  Any fractional interest in a Unit shall be paid in cash on
final distribution.  In the event of a termination of service, a Director may
elect to have Stock Units credited to the Director's Stock Unit Account and
Dividend Equivalent Stock Account paid and distributed in the form of cash or a
combination of whole shares of Common Stock and cash by making a written
election (on forms provided by the Corporation) at least six months prior to
receipt by a Director of any distribution as to the percentage the Director
elects to receive in the form of cash and the percentage the Director elects to
receive in whole shares of Common Stock.

          (d)  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).
<PAGE>
 
          (e)  Limitations of Distributions.  Notwithstanding anything herein to
the contrary, no Units may be distributed prior to the six month anniversary of
the crediting of such Units to the Director's Stock Unit Account.


     4.5. 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 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,
          and shall not create a security interest in any property although the
          Corporation shall reserve shares of Common Stock 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 or cash in the future,
          in accordance with the Plan. 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 Article shall be
          subject to adjustment in accordance with Section 7.1.

     5.2. Non-transferability of Options.  Options shall not be assignable nor
transferable by the Director otherwise than by bequest or by the laws of
descent.  Options shall be exercisable during the Director's lifetime only by

of a Beneficiary is not a prohibited transfer.

     5.3. Vesting; Term of Options.  Options shall become exercisable on the day
following the first anniversary of the date the Options are granted and, subject
to Section 5.3, shall expire on the tenth anniversary of the date the Options

in Control or in the event a Director's service as director terminates by reason
of such Director's Retirement, death or Disability, all options shall become
exercisable.

     5.4. Payment of Exercise Price.  The Option's exercise price shall be paid
in cash at the time of exercise, except that in lieu of all or part of the cash,
the Director may tender Stock to the Corporation having a Fair Market Value

tendered Stock shall be determined as of the close of the business day
immediately preceding the day on which the Options are exercised.

     5.5  Rights as Stockholder.  A Director shall have no rights as a Common
Stockholder with respect to any unissued shares of Common Stock covered by an
Option until the date the Director exercises the Options and becomes the holder
of record of those shares of Common Stock.  Except as provided in Section 7.1,
no adjustment or other provision shall be made for dividends or other
stockholder rights.


                                  ARTICLE VI
                                ADMINISTRATION


     6.1. Administration.  This Plan shall be self-executing and operated as a
formula plan.  To the extent necessary for the operation of the Plan, it shall
be construed, interpreted and 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 7.2 hereof, the Board shall have no
discretionary authority with respect to the amount or price of any Award granted
under this Plan and no Director shall participate in any decision relating
solely to his or her benefits (other than approval of the Award).

     6.2. 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

other experts believed to be reliable and competent.  The Board or the committee
may delegate 
<PAGE>
 
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 by the Corporation.


                                  ARTICLE VII
                         PLAN CHANGES AND TERMINATION

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, the Committee shall make a proportionate and
equitable adjustment consistent with the effect of any such event on
stockholders generally (but without duplication if Dividend Equivalents are
credited) in the maximum number of shares of Common Stock reserved under the
Plan, in the number of Units granted under the Plan, and in the number, kind and
exercise price of Options granted under the Plan to prevent dilution or
enlargement of the rights of Directors under the Plan and outstanding Options.

     7.2. Amendments.  The Board of Directors shall have the right to amend this
Plan in whole or in part or to suspend or terminate this Plan.  No amendment,
suspension, or termination, however, may cancel or otherwise adversely affect in

or Dividend Equivalent Stock Account or (ii) Options awarded prior to the

rights or interests other than as provided in this Plan.  No Director shall have

payable under this Plan after his or her death, subject to applicable laws
(including any applicable community property and probate laws).

          (b)  Definition of Beneficiary.  A Director's "Beneficiary" or

under this Plan in the event of the Director's death.

     8.3. 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 Account or of shares of Stock upon the exercise of Options by
reducing the number of shares of Common Stock otherwise deliverable to the
Director by the appropriate number of shares (based on the Fair Market Value on
the day immediately preceding the payment) 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.

     8.4. Benefits Not Assignable; Obligations Binding Upon Successors.
Benefits of a Director under this Plan shall not be assignable or transferable
and any purported transfer, assignment, pledge or other encumbrance or
attachment of any payments or benefits under this Plan, or any interest therein,
other than pursuant to Section 8.2, shall not be permitted or recognized.
Obligations of the Corporation under this Plan shall be binding upon successors
of the Corporation.

     8.5. Governing Law; Severability.  The validity of this Plan or any of its
provisions shall be construed, administered and governed in all respects under
and by the laws of the State of Maryland.  If any provisions of this instrument
shall be held by a court of competent jurisdiction to be invalid or
unenforceable, the remaining provisions hereof shall continue to be fully
effective.

     8.6. Compliance With Laws.  This Plan and the offer, issuance and delivery
of shares of Common Stock and/or the payment and deferral of compensation under
this Plan are subject to compliance with all applicable federal and state laws,
rules and regulations (including but not limited to state and federal reporting,
registration, insider trading and other securities laws) and to such approvals
by any listing agency or any 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 the securities shall, if requested by the
Corporation, provide such assurances and representations to the Corporation as
the Corporation may deem necessary or desirable to assure compliance with all
applicable legal requirements.

     8.7. Plan Construction.  It is the intent of the Corporation that this Plan
satisfy and be interpreted in a manner that satisfies the applicable
requirements of Rule 16b-3 so that Directors will be entitled to the benefits of
Rule 16b-3 or other exemptive rules under Section 16 of the Exchange Act and
will not be subjected to liability thereunder.  Any contrary interpretation
shall be avoided.

     8.8. Headings Not Part of Plan.  Headings and subheadings in this Plan are

                              PURPOSE OF THE PLAN
                              -------------------


This plan is established to provide a further incentive to selected employees to
promote the success of Lockheed Martin Corporation by providing an opportunity
to receive additional compensation for above average performance measured
against individual and business unit goals.  The Plan is intended to achieve the
following:


     1.   Improved cost effectiveness.


     2.   Stimulate employees to work individually and as teams to meet
          objectives and goals consistent with enhancing shareholder values.


     3.   Facilitate the Company's ability to retain qualified employees and to
          attract top executive talent.

        STANDARD OF CONDUCT AND PERFORMANCE EXPECTATION
        -----------------------------------------------


     1.   It is expected that the business and individual goals and objectives
          established for this Plan will be accomplished in accordance with the
          Corporation's policy on ethical conduct in business with the
          Government and all other customers.  It is a prerequisite before any
          award can be considered that a participant will have acted in
          accordance with the Lockheed Martin Corporation Code of Ethics and
          Business Conduct and fostered an atmosphere to encourage all employees
          acting under the participants' supervision to perform their duties in
          accordance with the highest ethical standards.  Ethical behavior is
          imperative.  Thus, in achieving one's goals, their individual
          commitment and adherence to the Corporation's ethical standards will
          be considered paramount in determining awards under this Plan.


     2.   Plan participants whose individual performance is determined to be
          less than acceptable are not eligible to receive incentive awards.

     1.   CALCULATION OF PAYMENTS -- Incentive compensation payments to
          Participants shall be calculated in accordance with the formula and
          procedures set forth in Exhibit A hereto.  All such payments shall be

     2.   INDIVIDUAL PERFORMANCE FACTORS - The Individual Performance Factors of
          Participants, as provided in Exhibit A shall be determined by the
          sector president or corporate function head and approved by the

          determined by the Committee and the Committee shall review the
          Individual Performance Ratings of other Participants who are elected
          officers of the Company.  The Committee may at the request of any
          member of the Committee review the performance ratings of any other
          Participant or groups of Participants.  The Committee may make
          adjustments in any such performance factors as it considers
          appropriate.

     3.   COMPANY AND CORPORATE FACTORS - The company factors and corporate
          factors, as provided for in Exhibit A, shall be determined by the
          executive office and shall thereafter be reviewed with and be subject
          to the approval of the Committee. The Committee may make adjustments
          in any such factor as it considers appropriate. The executive office
          shall, as soon as feasible in each year, review with the Committee the
          company and corporate objectives which may relate to the determination
          of such company and corporate factors.

     4.   RECOMMENDATION BY THE COMMITTEE.


          A.   As early as feasible after the end of each year in respect of
               which incentive compensation payments are to be made, the
               Committee shall establish an incentive fund which shall be equal
               to a percentage, to be determined by the Committee at that time,
               to the Company's pretax earnings for the year in which incentive
               compensation payments are to be made. For purposes of the Plan,
               pretax earnings shall (i) consist of pretax earnings from
               operations; (ii) shall not include any earnings attributable to
               extraordinary items as determined by generally accepted
               accounting principles; and (iii) shall be computed prior to the
               deduction of incentive compensation payments to be paid under the
               Plan.

          B.   To the extent that the aggregate of all proposed payments of
               incentive compensation to all Participants as determined by the
               application of the formula set forth in Exhibit A (subject to any
               adjustments made by the Committee under Paragraph 2 or 3 above)
               exceeds the amount of the incentive fund as determined under
               Paragraph 4.A. above, all proposed payments of incentive
               compensation to Participants shall be reduced on a prorata basis.

          C.   If the Company's pretax earnings, as defined in Paragraph 4A, are
               less than the aggregate of all proposed payments of incentive
               compensation (as determined by the application of the formula set
               forth in Exhibit A subject to 2 or 3 above), the Committee may,
               in its discretion, establish an incentive fund without regard to
               the pretax earnings guideline of Paragraph 4A.  If the Committee
               does so, 
<PAGE>
 
               Paragraph 4B shall not apply and the Committee's recommendation
               to the Board of Directors shall both state that the pretax
               earnings guideline would be exceeded and set forth the reasons
               the Committee believes that the proposed incentive compensation
               payments should nevertheless be made.

          D.   The Committee will recommend to the Board of Directors the
               authorization of an appropriation to the Plan by the Company for
               distribution to Participants in an amount equal to the incentive
               fund as computed pursuant to the provisions of this Paragraph 4.

     5.   APPROPRIATIONS TO THE PLAN - The Board of Directors may,
          notwithstanding any provision of the Plan, make adjustments in any
          proposed incentive compensation payment under the Plan, and subject to
          any such adjustments, the Board of Directors will appropriate to the
          Plan the amount as recommended by the Committee for distribution to
          the Participants; provided that, the Board of Directors may
          appropriate an amount which is less than the amount recommended by the
          Committee in which event all proposed payments of incentive
          compensation to Participants shall be reduced on a prorata basis.

     6.   METHOD OF PAYMENT - The amount so determined for each Participant
          with respect to each calendar year shall be paid to such Participant
          in full or on a deferred basis as determined by the Committee.  Such
          determination as to deferred payments shall be governed by the
          Committee's judgement as to the time of payment best serving the
          interests of the Company.  Deferred payments shall be made pursuant to
          such terms and conditions, as may be determined or provided for the by
          the Committee, only to Participants who continue in the employ of the
          Company or are retired under a retirement plan approved by the Board
          of Directors, or to the estates of, or beneficiaries designated by,
          Participants who shall have died while in such employ or after such
          retirement.  In the event of termination of employment by a
          Participant for any reason other than such retirement or death, then
          such participant or his estate or his beneficiary or beneficiaries,
          shall after such termination receive a distribution  or distributions
          of any amounts deferred by the Committee, if any, the amount (not in
          excess of the unpaid deferred payments) and time of which shall be
          determined or provided for by the Committee. Participants may also
          elect to defer payments to the extend provided in the Lockheed Martin
          Corporation Deferred Management Incentive Plan.

     7.   RIGHTS OF PARTICIPANTS - All payments are subject to the discretion of
          the Board of Directors. No Participant shall have any right to require
          the Board of Directors to make any appropriation to the Plan for any
          calendar year, nor shall any Participant have any vested interest or
          property right in any share in   any amounts which may be appropriated
          to the Plan.  Payments made under the Plan and distributed to
          Participants shall not be recoverable from the Participant by the
          Company.

CALCULATION OF MANAGEMENT INCENTIVE COMPENSATION PAYMENTS


A. AWARD FORMULA
   -------------


1.    Incentive compensation payments will be calculated by multiplying the
      Participant's Annual Salary by the applicable "target" of the
      Participant's position (as defined in B), and that result will then be
      multiplied by the Individual Performance Factor (as defined in C). The
      resulting award will be increased or decreased proportionately based on
      the appropriate Organizational Factor (as defined in D).

  2.  Partial awards for Participants who terminate employment during a Plan
      Year may be recommended for consideration based on the following:
<PAGE>
 
   Termination Method         MICP Award
   ------------------         ----------

   Voluntary                  May be considered for a pro-rated award if on
                              active status December 1 of the Plan Year with a
                              minimum of six (6) full months as an active Plan
                              Participant during the Plan Year.

                              case at the discretion of the Sector President (or
                              Major Corporate Function Head) with a minimum of
                              (6) full months as an active Plan Participant
                              during the Plan Year.


   Retirement                 May be considered for a pro-rated award with a
                              minimum of (6) full months as an active
                              Participant during the Plan Year if Participant
                              goes directly into retirement status upon
                              termination.

3.    Pro-rated awards may be recommended for individuals who become
      Participants subsequent to the beginning of a Plan Year, and have a
      minimum of (6) full months as active Participants during the Plan Year.

      Any deviation requires Corporate Salary Board approval.

4.    Recommended awards for Participants whose MICP target levels change during
      the Plan Year will be pro-rated (based on old versus new target level), if
      the new target level is in effect for less than (9) months during the Plan
      Year.

      Any deviation requires Sector President or Corporate Executive Office
      review and approval as appropriate.

5.    The aggregate of all Participant's Incentive Awards determined under items
      C and D below will be recommended to the Committee for its consideration.

6.    Any calculation of incentive awards under this exhibit shall be subject to
      the provisions of the Plan and in the event of any conflict between the
      terms or application of this Exhibit A and the Plan, the Plan shall
      prevail.

               below expected levels.

0.00           Performance fails to meet job requirements.


D. ORGANIZATIONAL PERFORMANCE FACTORS
   ----------------------------------

  rating will depend on the assessment of the quality of performance by each
  operating unit, or the corporate staff in accomplishing the objectives based
  on the following schedule:

                 performance expectations.

          0.75   Met most objectives. Overall performance was good, but
                 not as high as possible or expected.

          0.50   Met few objectives, but overall performance not as good as
                 possible or expected.

          0.0    Did not achieve sufficient overall performance level.


2.   Intermediate organizational ratings, as deemed appropriate by the executive

                             --------------------

          The purposes of the Lockheed Martin Corporation Deferred Management
Incentive Compensation Plan (the "Deferral Plan") are to provide certain key
management employees of Lockheed Martin Corporation and its subsidiaries (the
"Company") the opportunity to defer receipt of Incentive Compensation awards
under the Lockheed Martin Corporation Management Incentive Compensation Plan
(the "MICP") and to encourage key employees to maintain a financial interest in
the Company's performance.  Except as expressly provided hereinafter, the
provisions of this Deferral Plan and the MICP shall be construed and applied
independently of each other.

          The Deferral Plan applies solely to MICP awards and expressly does not
apply to any special awards which may be made under any of the Company's other
incentive plans, except and to the extent specifically provided under the terms
of such other incentive plans and the relevant awards.

                                  -----------

                          ELECTION OF DEFERRED AMOUNT
                          ---------------------------

          1.  Timing of Deferral Elections.  An Eligible Employee may elect to
              ----------------------------                                    
defer Incentive Compensation for an Award Year by executing and delivering to
the Company a Deferral Agreement no later than October 15 of the Award Year or
such other date established by the Committee for an Award Year that is not later
than October 31 of that Award Year, provided that any election by a Section 16
Person shall be subject to the provisions of Section 4 of Article IV.  An
employee who first qualifies as an Eligible Employee after September 15 of an
Award Year may elect to defer Incentive Compensation for that Award Year by
entering into a Deferral Agreement up to thirty (30) days after the date on
which such employee first becomes a participant in the MICP.  An Eligible
Employee's Deferral Agreement shall be irrevocable when delivered to the
Company.  Each Deferral Agreement shall apply only to amounts deferred in that
Award Year and a separate Deferral Agreement must be completed for each Award
Year for which an Eligible Employee defers Incentive Compensation.

          2.  Amount of Deferral Elections.  An Eligible Employee's deferral
              ----------------------------                                  
election may be stated as:

                  (a) a dollar amount which is at least $5,000 and is an even
          multiple of $1,000,

                  (b) the greater of $5,000 or a designated percentage of the
          Eligible Employee's Incentive Compensation (adjusted to the next
          highest multiple of $1,000),

                  (c) the excess of the Eligible Employee's Incentive
          Compensation over a dollar amount specified by the Eligible Employee
          (which must be an even multiple of $1,000), or
<PAGE>
 
                                      -4-

                  (d) all of the Eligible Employee's Incentive Compensation.

An Eligible Employee's deferral election shall be effective only if the
Participant is awarded at least $10,000 of Incentive Compensation for that Award
Year, and, in the case of a deferral election under paragraph (c) of this
Section 2, only if the resulting excess amount is at least $5,000.

          3.  Effect of Taxes on Deferred Compensation.  The amount that would
              ----------------------------------------                  
otherwise be deferred and credited to an Eligible Employee's Account will be
reduced by the amount of any tax that the Company is required to withhold with
respect to the Deferred Compensation. The reduction for taxes shall be made
proportionately out of amounts otherwise allocable to the Interest Option and
the Company Stock Investment Option.


                                  ARTICLE IV
                                  ----------

                             CREDITING OF ACCOUNTS
                             ---------------------

          1.  Crediting of Deferred Compensation.  Incentive Compensation that
              ----------------------------------                              
has been deferred hereunder shall be credited to a Participant's Account as of
the day on which the Incentive Compensation would have been paid to the
Participant if no Deferral Agreement had been made.

          2.  Crediting of Earnings.  Earnings shall be credited to a
              ---------------------                                  
Participant's Account based on the investment option or options to which the
Account has been allocated, beginning with the day as of which Deferred
Compensation (or any reallocation under Section 4, 5, or 6 of Article IV) is
credited to the Participant's Account.  Any amount distributed from a
Participant's Account shall be credited with earnings through the last day of
the month preceding the month in which a distribution is to be made pursuant to
the Participant's election as set forth in Article V.  The earnings credited
under each of the investment options shall be determined as follows:

               (a) Interest Option:  The portion of a Participant's Account
                   ---------------                                         
          allocated to the Interest Option shall be credited with interest,
          compounded monthly, at a rate equivalent to the then published rate
          for computing the present value of future benefits at the time cost is
          assignable under Cost Accounting Standard 415, Deferred Compensation,
          as determined by the Secretary of the Treasury on a semi-annual basis
          pursuant to Pub. L. 92-41, 85 Stat. 97.
<PAGE>
 
                                      -5-

               (b) Company Stock Investment Option:  The portion of a
                   -------------------------------                   
          Participant's Account allocated to the Company Stock Investment Option
          shall be credited as if such amount had been invested in the Company's
          Common Stock at the published closing price of the Company's Common
          Stock on the last Trading Day preceding the day as of which Deferred
          Compensation (or any reallocation under Section 4, 5, or 6 of Article
          IV) is credited to the Participant's Account; this portion of the
          Participant's Account Balance shall reflect any subsequent
          appreciation or depreciation in the market value of the Company's
          Common Stock based on the closing price of the stock on the New York
          Stock Exchange on the last Trading Day of each month and shall reflect
          dividends on the Company's Common Stock as if such dividends had been
          reinvested in the Company's Common Stock.

               (c) Interest Crediting For Late Payments:  Notwithstanding the
                   ------------------------------------                      
          investment option to which a Participant's Account has been allocated,
          in the event payment does not commence by the last day of the month in
          which the Payment Date occurs, earnings shall be credited on the
          Participant's entire Account from the last day of the month preceding
          the Payment Date to the last day of the month preceding the actual
          commencement of payment at the rate set forth under Section 2(a) of
          this Article IV.  Interest credited under this Section 2(c) of this
          Article IV shall be paid on the date payment under the Plan first
          commences.

          3.  Selection of Investment Options.  Except as otherwise provided in
              -------------------------------                                  
this Deferral Plan, a Participant's investment selections shall be made as part
of his or her Deferral Agreement for an Award Year and shall be irrevocable with
respect to amounts deferred for that Award Year, and no subsequent reallocations
shall be made.  At the time of entering into a Deferral Agreement for any
subsequent Award Year, a Participant shall select the investment options for the
Deferred Compensation to be credited to the Participant's Account for that Award
Year.  A Participant's allocations between investment options shall be subject
to such minimum allocations as the Committee may establish.

          4.  Special Rules for Section 16 Persons.  Notwithstanding the
              ------------------------------------                      
foregoing, an election by a Section 16 Person to have Deferred Compensation
allocated to the Company Stock Investment Option shall be given effect only if
irrevocably made at least six months prior to the effective date of the
allocation.  If a Section 16 Person's Deferral Agreement for an Award Year is
entered into less than six months prior to the date that Deferred Compensation
is credited for that Award Year, and if he or she has elected to have any
portion of the Deferred Compensation for that Award Year allocated to the
Company Stock Investment Option, that portion shall initially be allocated to
the Interest Option and shall be reallocated and credited to the Company Stock
Investment Option as of the first day of the seventh month following the month
in which the Deferral Agreement was made.  An Eligible Employee who first
becomes a Section 16 Person after his or her Deferral Agreement has been entered
into for an Award Year shall be subject to the requirements of this Section 4,
except that such an Eligible Employee shall be permitted, within ten business
days after becoming a Section 16 Person, to make irrevocable modified investment
elections for that Award Year; any allocations to the 
<PAGE>
 
                                      -6-

Company Stock Investment Option on behalf of such a Section 16 Person shall be
deferred until the first day of the seventh month following the month in which
the Eligible Employee's modified election is made (or, if later, the first day
of the seventh month following the month in which the election period expires
without a modified election having been made).

          5.  Reallocations to Company Stock Investment Option.  Each Eligible
              ------------------------------------------------       
Employee for whom an account is maintained under the Deferred Management
Incentive Compensation Plan of Lockheed Corporation and its Subsidiaries (the
"Lockheed Plan") will be given a one-time opportunity during calendar year 1996
to make an irrevocable election to have all or a portion of that account balance
credited to the Eligible Employee's Account under this Deferral Plan and
reallocated to the Company Stock Investment Option. That reallocation shall be
credited to the Participant's Account under this Deferral Plan as of the first
day of the month following the last month in which such elections are permitted,
but in the case of a Section 16 Person not earlier than the first day of the
seventh month after the month in which the election is delivered to the Company.
If such a reallocation is made, the Eligible Employee's right to receive
benefits under the Lockheed Plan will be reduced accordingly, and the Company
will be released from liability under the Lockheed Plan for the amount
reallocated. Although the terms of this Deferral Plan shall generally apply to
any amount so reallocated, the Eligible Employee's irrevocable payment elections
under the Lockheed Plan will continue to apply to the reallocated amount.

          6.  Reallocations to Interest Option.  If benefit payments to a
              --------------------------------                           
Participant or Beneficiary are to be paid or commenced to be paid over a period
that extends more than six months after the date of the Participant's
termination of employment with the Company or death, the Participant or
Beneficiary, as applicable, may elect irrevocably at any time after the
Participant's termination of employment or death and before the commencement of
benefit payments to have the portion of the Participant's Account that is
allocated to the Company Stock Investment Option reallocated to the Interest
Option.  A reallocation under this Section 5 shall take effect as of the first
day of the month following the month in which an executed reallocation election
is delivered to the Company, but in the case of a Section 16 Person not earlier
than the first day of the seventh month following the month in which the
reallocation election is delivered to the Company.

                              PAYMENT OF BENEFITS
                              -------------------

          1.  General.  The Company's liability to pay benefits to a Participant
              -------                                                           
or Beneficiary under this Deferral Plan shall be measured by and shall in no
event exceed the Participant's Account Balance.  Except as otherwise provided in
this Deferral Plan, a Participant's Account Balance shall be paid to him in
accordance with the Participant's elections under Sections 2 and 3 of this
Article, and such elections shall be continuing and irrevocable.  All benefit
payments shall be made in cash and, except as otherwise provided, shall reduce
allocations to the Interest Option and the Company Stock Investment Option in
the same proportions that the Participant's Account Balance is allocated between
those investment options at the end of the month preceding the date of
distribution.  Notwithstanding the foregoing, no amount shall be distributed to
a Section 16 Person under this Deferral Plan unless the amount was allocated to
the Participant's Account at least six months prior to the date of distribution
or no portion of the amount was allocated to the Company Stock Investment
Option.

          2.  Election for Commencement of Payment.  At the time a Participant
              ------------------------------------                            
first completes a Deferral Agreement, he or she shall elect from among the
following options governing the date on which the payment of benefits shall
commence:

               (A)  Payment to begin on or about the January 15th or July 15th
                    next following the date of the Participant's termination of
                    employment with the Company for any reason.

               (B)  Payment to begin on or about January 15th of the year next
                    following the year in which the Participant terminates
                    employment with the Company for any reason.

               (C)  Payment to begin on or about the January 15th or July 15th
                    next following the date on which the Participant has both
                    terminated employment with the Company for any reason and
                    attained the age designated by the Participant in the
                    Deferral Agreement.
<PAGE>
 
                                      -8-


          3.  Election for Form of Payment.  At the time a Participant first
              ----------------------------                                  
completes a Deferral Agreement, he or she shall elect the form of payment of his
or her Account Balance from among the following options:

               (A)  A lump sum.

               (B)  Annual payments for a period of years designated by the
                    Participant which shall not exceed fifteen (15).  The amount
                    of each annual payment shall be determined by dividing the
                    Participant's Account Balance at the end of the month prior
                    to such payment by the number of years remaining in the
                    designated installment period.  The installment period may
                    be shortened, in the sole discretion of the Committee, if
                    the Committee at any time determines that the amount of the
                    annual payments that would be made to the Participant during
                    the designated installment period would be too small to
                    justify the maintenance of the Participant's Account and the
                    processing of payments.

          4.  Prospective Change of Payment Elections.  At the time of entering
              ---------------------------------------                          
into a Deferral Agreement for an Award Year, a Participant may modify his
payment elections under Sections 2 and 3 with respect to the portion of his or
her Account allocable to the amounts to be deferred for that Award Year and
subsequent Award Years.  If a Participant has different payment elections in
effect, the Company shall maintain sub-accounts for the Participant to determine
the amounts subject to each payment election; no modification of payment
elections will be accepted if it would require the Company to maintain more than
five (5) sub-accounts within the Participant's Account in order to make payments
in accordance with the Participant's elections.

          5.  Acceleration upon Early Termination.  Notwithstanding a
              -----------------------------------                    
Participant's payment elections under Sections 2 and 3, if the Participant
terminates employment with the Company other than by reason of layoff, death or
disability and before the Participant is eligible to commence receiving
retirement benefits under a pension plan maintained by the Company (or before
the Participant has attained age 55 if the Participant does not participate in
such a pension plan), the Participant's Account Balance shall be distributed to
him or her in a lump sum on or about the January 15th or July 15th next
following the date of the Participant's termination of employment with the
Company.

          6.  Death Benefits.  Upon the death of a Participant before a complete
              --------------                                                    
distribution of his or her Account Balance, the Account Balance will be paid to
the Participant's Beneficiary in accordance with the payment elections
applicable to the Participant.  If a Participant dies while actively employed or
otherwise before the payment of benefits has commenced, payments to the
Beneficiary shall commence on the date payments to the Participant would have
commenced, taking account of the Participant's termination of employment (by
death or before) and, if applicable, by postponing commencement until after the
date the Participant would have attained the commencement age specified by the
Participant.  Whether the Participant dies before or after the commencement of
distributions, payments to the Beneficiary shall be made for the period or
remaining period elected by the Participant.

          7.  Early Distributions in Special Circumstances.  Notwithstanding a
              --------------------------------------------                    
Participant's payment elections under Sections 2 and 3 of this Article V, a
Participant or Beneficiary may request an earlier distribution in the following
limited circumstances:

                  (a) Hardship Distributions. Subject to the last sentence of
                      ----------------------     
          this Section 7(a) with respect to Section 16 Persons, the Committee
          shall have the power and discretion at any time to approve a payment
          to a Participant if the Committee determines that the Participant is
          suffering from a serious financial emergency caused by circumstances
          beyond the Participant's control which would cause a hardship to the
          Participant unless such payment were made. Any such hardship payment
          will be in a lump sum and will not exceed the lesser of (i) the amount
          necessary to satisfy the financial emergency (taking account of the
          income tax liability associated with the distribution), or (ii) the
          Participant's Account Balance. In the event that a Section 16 Person
          seeks a hardship withdrawal under this Section 7(a), the distribution
          will be made first out of the portion of the Participant's Account, if
          any, allocated to the Interest Option; if the hardship distribution
          cannot be satisfied in full out of amounts allocated to the Interest
          Option, no distribution will be made from the portion of the
          Participant's Account allocated to the Company Stock Investment Option
          until the seventh month following the month in which the Participant's
          application under this Section 7(a) was made, which application shall
          be irrevocable when made.

             (b) Withdrawal with Forfeiture. A Participant may elect at any time
                 --------------------------                    
          to withdraw ninety percent (90%) of the amount credited to the
          Participant's Account. If such a withdrawal is made, the remaining ten
          percent (10%) of the Participant's Account shall be permanently
          forfeited, and the Participant will be prohibited from deferring any
          amount under the Deferral Plan for the Award Year in which the
          withdrawal is received (or the first Award Year in which any portion
          of the withdrawal is received). In the event that a Section 16 Person
          seeks a withdrawal under this Section 7(b), any portion of the Section
          16 Person's Account allocated to the Company Stock Investment Option
          will not be subject to distribution or forfeiture until the seventh
          month following the month in which the Participant's election under
          this Section 7(b) was made, which election shall be irrevocable when
          made; any portion of the Section 16 Person's Account allocated to the
          Interest Option will be subject to immediate distribution and
          forfeiture; the ten percent forfeiture shall be separately applied to
          each such portion of the Section 16 Person's Account at the time of
          distribution.

               (c) Death or Disability.  In the event that a Participant dies or
                   -------------------                             
          becomes permanently disabled before the Participant's entire Account
          Balance has been distributed, the Committee, in its sole discretion,
          may modify the timing of distributions from the Participant's Account,
          including the commencement date and number 
<PAGE>
 
                                      -10-

          of distributions, if it concludes that such modification is necessary
          to relieve the financial burdens of the Participant or Beneficiary.

          8.  Acceleration upon Change in Control.
              ----------------------------------- 

               (a) Notwithstanding any other provision of the Deferral Plan, the
          Account Balance of each Participant shall be distributed in a single
          lump sum within fifteen (15) calendar days following a "Change in
          Control."

               (b) For purposes of this Deferral Plan, a Change in 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 Company representing 25% or
               more of the combined voting power of the Company's then
               outstanding voting securities entitled to vote in the election of
               directors of the Company.

                        (2) The Company 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 Company (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 Company representing 25% or more of the
               combined voting power of the Company's then outstanding
               securities entitled to vote in the election of directors of the
               Company.

                        (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 

                
<PAGE>
 
                                      -11-

               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 Company approve a plan of
               liquidation and dissolution or the sale or transfer of
               substantially all of the Company's business and/or assets as an
               entirety to an entity that is not a Subsidiary.

               (c) Notwithstanding the provisions of Section 8(a), if a
          distribution in accordance with the provisions of Section 8(a) would
          result in a nonexempt short-swing transaction under Section 16(b) of
          the Exchange Act with respect to any Section 16 Person, then the date
          of distribution to such Section 16 Person shall be delayed until the
          earliest date upon which the distribution either would not result in a
          nonexempt short-swing transaction or would otherwise not result in
          liability under Section 16(b) of the Exchange Act.

                (d) This Section 8 shall apply only to a Change in Control of
          Lockheed Martin Corporation and shall not cause immediate payout of
          Deferred Compensation in any transaction involving the Company's sale,
          liquidation, merger, or other disposition of any subsidiary.

                (e) The Committee may cancel or modify this Section 8 at any
          time prior to a Change in Control. In the event of a Change in
          Control, this Section 8 shall remain in force and effect, and shall
          not be subject to cancellation or modification for a period of five
          years, and any defined term used in Section 8 shall not, for purposes
          of Section 8, be subject to cancellation or modification during the
          five year period.

          9.  Deductibility of Payments.  In the event that the payment of
              -------------------------                                   
benefits in accordance with the Participant's elections under Sections 2 and 3
would prevent the Company from claiming an income tax deduction with respect to
any portion of the benefits paid, the Committee shall have the right to modify
the timing of distributions from the Participant's Account as necessary to
maximize the Company's tax deductions.  In the exercise of its discretion to
adopt a modified distribution schedule, the Committee shall undertake to have
distributions made at such times and in such amounts as most closely approximate
the Participant's elections, consistent with the objective of maximum
deductibility for the Company.  The Committee shall have no authority to reduce
a Participant's Account Balance or to pay aggregate benefits less than the
Participant's Account Balance in the event that all or a portion thereof would
not be deductible by the Company.

                                      -12-

          10.  Change of Law.  Notwithstanding anything to the contrary herein,
               -------------                                                   
if the Committee determines in good faith, based on consultation with counsel,
that the federal income tax treatment or legal status of the Plan has or may be
adversely affected by a change in the Internal Revenue Code, Title I of the
Employee Retirement Income Security Act of 1974, or other applicable law or by
an administrative or judicial construction thereof, the Committee may direct
that the Accounts of affected Participants or of all Participants be distributed
as soon as practicable after such determination is made, to the extent deemed
necessary or advisable by the Committee to cure or mitigate the consequences, or
possible consequences of, such change in law or interpretation thereof.

          11.  Tax Withholding.  To the extent required by law, the Company
               ---------------                                             
shall withhold from benefit payments hereunder, or with respect to any Incentive
Compensation deferred hereunder, any Federal, state, or local income or payroll
taxes required to be withheld and shall furnish the recipient and the applicable
government agency or agencies with such reports, statements, or information as
may be legally required.


                                  ARTICLE VI
                                  ----------

                        EXTENT OF PARTICIPANTS' RIGHTS
                        ------------------------------

          1.  Unfunded Status of Plan.  This Deferral Plan constitutes a mere
              -----------------------                                        
contractual promise by the Company to make payments in the future, and each
Participant's rights shall be those of a general, unsecured creditor of the
Company.  No Participant shall have any beneficial interest in any specific
assets that the Company may hold or set aside in connection with this Deferral
Plan.  Notwithstanding the foregoing, to assist the Company in meeting its
obligations under this Deferral Plan, the Company may set aside assets in a
trust described in Revenue Procedure 92-64, 1964-2 C.B. 44, and the Company may
direct that its obligations under this Deferral Plan be satisfied by payments
out of such trust.  The assets of any such trust will remain subject to the
claims of the general creditors of the Company.  It is the Company's intention
that the Plan be unfunded for Federal income tax purposes and for purposes of
Title I of the Employee Retirement Income Security Act of 1974.

          2.  Nonalienability of Benefits.  A Participant's rights under this
              ---------------------------                                    
Deferral Plan shall not be assignable or transferable and any purported
transfer, assignment, pledge or other encumbrance or attachment of any payments
or benefits under this Deferral Plan, or any interest therein shall not be
permitted or recognized, other than the designation of, or passage of payment
rights to, a Beneficiary.

                                  -----------

                           AMENDMENT OR TERMINATION
                           ------------------------

          1.  Amendment.  The Board may amend, modify, suspend or discontinue
              ---------                                                      
this Deferral Plan at any time subject to any shareholder approval that may be
required under applicable law, provided, however, that no such amendment shall
have the effect of reducing a Participant's Account Balance or postponing the
time when a Participant is entitled to receive a distribution of his Account
Balance.  Further, no amendment may alter the formula for crediting interest to
Participants' Accounts with respect to amounts for which deferral elections have
previously been made, unless the amended formula is not less favorable to
Participants than that previously in effect, or unless each affected Participant
consents to such change.

          2.  Termination.  The Board reserves the right to terminate this Plan
              -----------                                                      
at any time and to pay all Participants their Account Balances in a lump sum
immediately following such termination or at such time thereafter as the Board
may determine; provided, however, that if a distribution in accordance with the
provisions of this Section 2 would otherwise result in a nonexempt short-swing
transaction under Section 16(b) of the Exchange Act, the date of distribution
with respect to any Section 16 Person shall be delayed until the earliest date
upon which the distribution either would not result in a nonexempt short-swing
transaction or would otherwise not result in liability under Section 16(b) of
the Exchange Act.

          3.  Transfer of Liability.  The Board reserves the right to transfer
              ---------------------                                  
to another entity all of the obligations of Company with respect to a
Participant under this Plan if such entity agrees pursuant to a binding written
agreement to assume all of the obligations of the Company under this Plan with
respect to such Participant.


                                 ARTICLE VIII
                                 ------------

                                ADMINISTRATION
                                --------------

          1.  The Committee.  This Deferral 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 Deferral Plan to
comply with the disinterested administration requirements of Rule 16b-3 of the
Exchange Act.  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.  The
Committee shall have full authority to interpret the Plan, and interpretations
of the Plan by the Committee shall be final and binding on all parties.

          2.  Delegation and Reliance.  The Committee may delegate to the
              -----------------------                                    
officers or employees of the Company 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 Deferral Plan in accordance with its terms and purpose, 
<PAGE>
 
                                      -14-

except that the Committee may not delegate any authority the delegation of which
would cause this Deferral Plan to fail to satisfy the applicable requirements of
Rule 16b-3. In making any determination or in taking or not taking any action
under this Deferral Plan, the Committee may obtain and rely upon the advice of
experts, including professional advisors to the Company. No member of the
Committee or officer of the Company who is a Participant hereunder may
participate in any decision specifically relating to his or her individual
rights or benefits under the Deferral Plan.

          3.  Exculpation and Indemnity.  Neither the Company nor any member of
              -------------------------                                        
the Board or of the Committee, nor any other person participating in any
determination of any question under this Deferral Plan, or in the
interpretation, administration or application thereof, shall have any liability
to any party for any action taken or not taken in good faith under this Deferral
Plan or for the failure of the Deferral Plan or any Participant's rights under
the Deferral Plan to achieve intended tax consequences, to qualify for exemption
or relief under Section 16 of the Exchange Act and the rules thereunder, or to
comply with any other law, compliance with which is not required on the part of
the Company.

          4.  Facility of Payment.  If a minor, person declared incompetent, or
              -------------------                                              
person incapable of handling the disposition of his or her property is entitled
to receive a benefit, make an application, or make an election hereunder, the
Committee may direct that such benefits be paid to, or such application or
election be made by, the guardian, legal representative, or person having the
care and custody of such minor, incompetent, or incapable person.  Any payment
made, application allowed, or election implemented in accordance with this
Section shall completely discharge the Company and the Committee from all
liability with respect thereto.

          5.  Proof of Claims.  The Committee may require proof of the death,
              ---------------                                                
disability, incompetency, minority, or incapacity of any Participant or
Beneficiary and of the right of a person to receive any benefit or make any
application or election.

          6.  Claim Procedures.  The procedures when a claim under this Plan is
              ----------------                                                 
denied by the Committee are as follows:

               (A)  The Committee shall:

                    (i)   notify the claimant within a reasonable time of such
                          denial, setting forth the specific reasons therefor;
                          and
 
                    (ii)  afford the claimant a reasonable opportunity for a
                          review of the decision.

               (B)  The notice of such denial shall set forth, in addition to
                    the specific reasons for the denial, the following:
 
                    (i)   identification of pertinent provisions of this Plan;
<PAGE>
 
                                      -15-


                    (ii)  such additional information as may be relevant to the
                          denial of the claim; and

                    (iii) an explanation of the claims review procedure and
                          advice that the claimant may request an opportunity to
                          submit a statement of issues and comments.

               (C)  Within sixty days following advice of denial of a claim,
                    upon request made by the claimant, the Committee shall take
                    appropriate steps to review its decision in light of any
                    further information or comments submitted by the claimant.
                    The Committee may hold a hearing at which the claimant may
                    present the basis of any claim for review.
 
               (D)  The Committee shall render a decision within a reasonable
                    time (not to exceed 120 days) after the claimant's request
                    for review and shall advise the claimant in writing of its
                    decision, specifying the reasons and identifying the
                    appropriate provisions of the Plan.


                                  ARTICLE IX
                                  ----------

                     GENERAL AND MISCELLANEOUS PROVISIONS
                     ------------------------------------

          1.  Neither this Deferral Plan nor a Participant's Deferral Agreement,
either singly or collectively, shall in any way obligate the Company to continue
the employment of a Participant with the Company, nor does either this Deferral
Plan or a Deferral Agreement limit the right of the Company at any time and for
any reason to terminate the Participant's employment.  In no event shall this
Plan or a Deferral Agreement, either singly or collectively, by their terms or
implications constitute an employment contract of any nature whatsoever between
the Company and a Participant.  In no event shall this Plan or a Plan Agreement,
either singly or collectively, by their terms or implications in any way
obligate the Company to award Incentive Compensation to any Eligible Employee
for any Award Year, whether or not the Eligible Employee is a Participant in the
Deferral Plan for that Award Year, nor in any other way limit the right of the
Company to change an Eligible Employee's compensation or other benefits.

          2.  Incentive Compensation deferred under this Deferral Plan shall not
be treated as compensation for purposes of calculating the amount of a
Participant's benefits or contributions under any pension, retirement, or other
plan maintained by the Company, except as provided in such other plan.

          3.  Any written notice to the Company referred to herein shall be made
by mailing or delivering such notice to the Company at 6801 Rockledge Drive,
Bethesda, Maryland 20817, to the attention of the Vice President, Human
Resources.  Any written notice to a Participant shall be made by delivery to the
Participant in person, through electronic transmission, or by mailing such
<PAGE>
 
                                      -16-

notice to the Participant at his or her place of residence or business address.

          4.  In the event it should become impossible for the Company or the
Committee to perform any act required by this Plan, the Company or the Committee
may perform such other act as it in good faith determines will most nearly carry
out the intent and the purpose of this Deferral Plan.

          5.  By electing to become a Participant hereunder, each Eligible
Employee shall be deemed conclusively to have accepted and consented to all of
the terms of this Deferral Plan and all actions or decisions made by the
Company, the Board, or Committee with regard to the Deferral Plan.

          6.  The provisions of this Deferral Plan and the Deferral Agreements
hereunder shall be binding upon and inure to the benefit of the Company, its
successors, and its assigns, and to the Participants and their heirs, executors,
administrators, and legal representatives.

          7.  A copy of this Deferral Plan shall be available for inspection by
Participants or other persons entitled to benefits under the Plan at reasonable
times at the offices of the Company.

          8.  The validity of this Deferral Plan or any of its provisions shall
be construed, administered, and governed in all respects under and by the laws
of the State of Maryland, except as to matters of Federal law.  If any
provisions of this instrument shall be held by a court of competent jurisdiction
to be invalid or unenforceable, the remaining provisions hereof shall continue
to be fully effective.

          9.  This Deferral Plan and its operation, including but not limited
to, the mechanics of deferral elections, the issuance of securities, if any, or
the payment of cash hereunder is 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 such other approvals by any listing, regulatory or governmental
authority as may, in the opinion of counsel for the Company, be necessary or
advisable in connection therewith.

          10.  It is the intent of the Company that this Deferral Plan satisfy
and be interpreted in a manner, that, in the case of Participants who are or may
be Section 16 Persons, satisfies any applicable requirements of Rule 16b-3 of
the Exchange Act or other exemptive rules under Section 16 of the Exchange Act
and will not subject Section 16 Persons to short-swing profit liability
thereunder.  If any provision of this Deferral Plan would otherwise frustrate or
conflict with the intent expressed in this Section 10, 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.  Similarly, any action or
election by a Section 16 Person with respect to the Deferral Plan to the extent
possible shall be interpreted and deemed amended so as to avoid liability under
Section 16 or, if this is not possible, to the extent necessary to avoid
liability under Section 16, shall be deemed ineffective.  Notwithstanding
anything to the contrary in this Deferral Plan, the provisions of this Deferral
Plan may at any time be bifurcated by the

Board or the Committee in any manner so that certain provisions of this Deferral
Plan are applicable solely to Section 16 Persons. Notwithstanding any other
provision of this Deferral Plan to the contrary, if a distribution which would
otherwise occur is prohibited or proposed to be delayed because of the
provisions of Section 16 of the Exchange Act or the provisions of the Deferral
Plan designed to ensure compliance with Section 16, the Section 16 Person
involved may affirmatively elect in writing to have the distribution occur in
any event; provided that the Section 16 Person shall concurrently enter into
arrangements satisfactory to the Committee in its sole discretion for the
satisfaction of any and all liabilities, costs and expenses arising from this
election.

          11.  Notwithstanding any other provision of this Deferral Plan, each
Eligible Employee who is a Section 16 Person and has entered into a Deferral
Agreement prior to the initial distribution of a prospectus relating to this
Deferral Plan shall be entitled, during a ten-business-day period following the
initial distribution of that prospectus, to make an irrevocable election to (i)
receive a distribution of all or any portion of his or her Account Balance
attributable to Deferred Compensation for the 1995 Award Year during the seventh
month following the month of the election, or (ii) reallocate all or any part of
his or her Account Balance attributable to Deferred Compensation for the 1995
Award Year to a different investment option as of the end of the sixth month
following the month of the election.

          12.  At no time shall the aggregate Account Balances of all
Participants to the extent allocated to the Company Stock Investment Option
exceed an amount equal to the then fair market value of 5,000,000 shares of the
Company's Common Stock, nor shall the cumulative amount of Incentive
Compensation deferred under this Deferral Plan by all Eligible Employees for all
Award Years exceed $250,000,000.

                    ---------------------------------------

          This Deferral Plan was adopted by the Board on July 27, 1995 and
became effective upon adoption to awards of Incentive Compensation for the
Company's fiscal year ending December 31, 1995 and subsequent fiscal years;
provided, however, that with respect to Section 16 Persons, the availability of
the Company Stock Investment Option is conditioned upon the approval of this
Deferral Plan by the stockholders of Lockheed Martin Corporation.  In the event
that this Deferral Plan is not approved by the stockholders, then Section 16
Persons shall not be entitled to have Deferred Compensation allocated to the
Company Stock Investment Option; any prior elections by Section 16 Persons to
have allocations made to the Company Stock Investment Option shall retroactively
be deemed ineffective, and the Account Balances of those Section 16 Persons
shall be restated as if all of their Deferred Compensation had been allocated to
the Interest Option at all times.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF              Lockheed Martin Corporation
FINANCIAL CONDITION AND RESULTS OF OPERATIONS                  
December 31, 1998


- --------------------------------------------------------------------------------
Lockheed Martin Corporation (Lockheed Martin or the Corporation) is engaged in
the conception, research, design, development, manufacture, integration and
operation of advanced technology systems, products and services. The Corporation
serves customers in both domestic and international defense and commercial
markets, with its principal customers being agencies of the U.S. Government. The
following discussion should be read in conjunction with the audited consolidated
financial statements included herein. 

Common Stock Split 

In October 1998, the Board of Directors of the Corporation authorized a
two-for-one split of the Corporation's common stock in the form of a stock
dividend which was effected on December 31, 1998. In the following discussion,
all references to shares of common stock and per share amounts have been
restated to reflect the stock split. 

Transaction Agreement with COMSAT Corporation 

In September 1998, the Corporation and COMSAT Corporation (COMSAT) announced
that they had entered into an agreement to combine the companies in a two-phase
transaction with a total estimated value of approximately $2.7 billion at the
date of the announcement (the Merger). In connection with the first phase of
this transaction, the Corporation commenced a cash tender offer (the Tender
Offer) to purchase up to 49 percent, subject to certain adjustments, of the
outstanding shares of common stock of COMSAT on the date of purchase at a price
of $45.50 per share, with an estimated value of $1.2 billion. Under the Merger
agreement, the Tender Offer will be extended for periods of up to 60 days until
the earlier of (i) September 18, 1999, or (ii) satisfaction of certain
conditions to closing. The consummation of the Tender Offer is subject to, among
other things, the approval of the Merger by the stockholders of COMSAT and
certain regulatory approvals, including approval by the Federal Communications
Commission (FCC). The stockholders of COMSAT are expected to vote on the
proposed Merger at COMSAT's annual meeting of stockholders on June 18, 1999.
Upon completion of this phase of the transaction, the Corporation will account
for its investment in COMSAT under the equity method of accounting. The second
phase of the transaction, which will result in consummation of the Merger, will
be accomplished by an exchange of one share of Lockheed Martin common stock for
each share of COMSAT common stock. Consummation of the Merger is subject to,
among other things, the enactment of legislation necessary to allow Lockheed
Martin to acquire the remaining shares of COMSAT common stock and certain
additional regulatory approvals, including anti-trust clearance by the
Department of Justice. The Merger will be accounted for under the purchase
method of accounting. 

     The Corporation is not currently designated by the FCC as an "authorized
common carrier," and as such is prohibited from owning more than 10 percent of
COMSAT. The Corporation has filed an application with the FCC to be designated
an "authorized common carrier" and to purchase up to 49 percent of COMSAT. On
January 21, 1999, the Chairman of the House Committee on Commerce and the
Chairman of the Senate Subcommittee on Communications sent a letter to the FCC
urging the FCC not to take any action to permit any company to purchase more
than 10 percent of COMSAT prior to Congress adopting satellite industry reform
legislation. If the FCC were to delay or slow its review of the Corporation's
filings with respect to the Tender Offer, and if Congress does not make rapid
progress on satellite industry reform legislation, the Tender Offer may not be
consummated by September 18, 1999. If this occurs, either party may terminate
the Merger Agreement or both parties may elect to amend the Merger Agreement to
extend this date. If the FCC's review is not delayed or slowed and the Tender
Offer is consummated, but the legislative process relative to satellite industry
reform legislation moves slowly, the Merger is unlikely to occur in 1999.

Acquisitions and Divestitures 

In November 1997, Lockheed Martin exchanged all of the outstanding capital stock
of a wholly-owned subsidiary for all of the outstanding Series A preferred stock
held by General Electric Company (GE) and certain subsidiaries of GE (the GE
Transaction). The Series A preferred stock was convertible into approximately 58
million shares of Lockheed Martin common stock. The Lockheed Martin subsidiary
was composed of two non-core commercial business units which contributed
approximately five percent of the Corporation's 1997 net sales, Lockheed
Martin's investment in a telecommunications partnership and approximately $1.6
billion in cash. The GE Transaction was accounted for at fair value, and
resulted in the reduction of the Corporation's stockholders' equity by $2.8
billion and the recognition of a tax-free gain of approximately $311 million in
other income and expenses. Also see the discussion under the caption "Results of
Operations" regarding the impact of the GE Transaction on the computation of
1997 earnings per share. In 1998 and 1997, in connection with the GE
Transaction, the Corporation issued notes to a wholly-owned subsidiary of GE for
$210 million, bearing interest at 5.73%, and $1.4 billion, bearing interest at
6.04%, respectively. The notes are due November 17, 2002.

     In July 1997, the Corporation and Northrop Grumman Corporation (Northrop
Grumman) announced that they had entered into an agreement to combine the
companies whereby Northrop Grumman would become a wholly-owned subsidiary of
Lockheed Martin. The proposed merger with Northrop Grumman was terminated by the
Board of Directors of Lockheed Martin in July 1998.

     In March 1997, the Corporation executed a definitive agreement valued at
approximately $525 million to reposition ten non-core business units as a new
independent company, L-3 Communications Corporation (L-3), in which the
Corporation retained an approximate 35 percent ownership interest at closing.
These business units contributed approximately two percent of the Corporation's
net sales during the three month period ended March 31, 1997. The transaction,
which closed in April 1997 with an effective date of March 30, 1997, did not
have a material impact on the Corporation's earnings. The Corporation's
ownership percentage was reduced to approximately 25 percent in the second
quarter of 1998 as a result of an initial public offering of L-3's common stock.
In the first quarter of 1999, the Corporation's ownership percentage was further
reduced to approximately 7 percent as a result of a secondary offering of L-3's
common stock which included 4.5 million shares previously owned by the
Corporation. The 1998 transaction increased net earnings by $12 million, and the
1999 transaction is estimated to increase first quarter 1999 net earnings by an
amount between $75 million and $85 million.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
AND RESULTS OF OPERATIONS (Continued)
December 31, 1998


- --------------------------------------------------------------------------------
     During the third quarter of 1996, the Corporation announced its intention
to distribute via an exchange offer its interest in Martin Marietta Materials,
Inc. (Materials) to its stockholders. In October 1996, the exchange was
consummated, subsequent to which the Corporation had no remaining ownership
interest in Materials. The transaction was accounted for at fair value,
resulting in a reduction in the Corporation's stockholders' equity of $750
million and the recognition of a pretax gain of $365 million in other income and
expenses.

     In November 1996, the Corporation announced the proposed divestiture of two
of its business units, Armament Systems and Defense Systems. This transaction,
which concluded with the Corporation's receipt of $450 million in cash in
January 1997, had no pretax effect on the results of operations for 1997 or
1996. 

     On a combined basis, the Materials exchange and the Armament Systems and
Defense Systems divestiture noted above increased 1996 net earnings by $351
million.

  In April 1996, the Corporation consummated its business combination with Loral
Corporation (Loral) for a total purchase price, including acquisition costs, of
approximately $7.6 billion (the Loral Transaction). In addition to the
acquisition of Loral's defense electronics and systems integration businesses,
the Loral Transaction resulted in the Corporation acquiring shares of preferred
stock of Loral Space & Communications, Ltd. (Loral SpaceCom), a newly-formed
company, which were convertible into 20 percent of Loral SpaceCom's common stock
on a diluted basis at the date of acquisition. The operations of the businesses
acquired in connection with the Loral Transaction have been included in the
results of operations of the Corporation since April 1996. 

Formation of Lockheed Martin Global Telecommunications 

In August 1998, the Corporation announced the formation of Lockheed Martin
Global Telecommunications, Inc. (Global Telecommunications), a wholly-owned
subsidiary of the Corporation. Global Telecommunications will combine
investments in several existing joint ventures and certain elements of the
Corporation under a dedicated management team focused on capturing a greater
portion of the worldwide telecommunications services market. Effective January
1, 1999, the following operations and investments became a part of Global
Telecommunications: Lockheed Martin Intersputnik, Ltd., a strategic venture with
Moscow-based Intersputnik that is scheduled to deploy its first satellite in
1999; Astrolink/TM/ International Ltd., a strategic venture that will provide
global interactive multimedia services using next-generation broadband satellite
technology; the elements of Lockheed Martin Missiles & Space, Lockheed Martin
Management & Data Systems and Lockheed Martin Western Development Laboratories
that provide commercial communications capabilities; the Corporation's
investment in Americom Asia Pacific, LLC, a joint venture with GE Americom that
is scheduled to launch a satellite in 1999 that will serve broadcasters in the
Asia-Pacific region; and the Corporation's investment in ACeS International
Limited, a joint venture that will provide cellular telephone communications in
regions of Asia. Additionally, the Corporation intends to combine the operations
of Global Telecommunications and COMSAT upon consummation of the Tender Offer
and the Merger.

Results of Operations

The Corporation's operating cycle is long-term and involves many types of
production contracts with varying production delivery schedules. Accordingly,
the results of a particular year, or year-to-year comparisons of recorded sales
and profits, may not be indicative of future operating results. The following
comparative analysis should be viewed in this context.


                           [BAR CHART APPEARS HERE]

Net Sales
(In millions)

'96/(a)/       $26,875
'97            $28,069
'98            $26,266

(a) Reflects the business combination with Loral Corporation since April 1996.


     The Corporation's consolidated net sales for 1998 were $26.3 billion, a
decrease of six percent compared to 1997. Net sales during 1997 were $28.1
billion, an increase of four percent compared to 1996. Excluding the impact of
the operations of divested entities, which are discussed below, net sales for
1998 would have remained relatively consistent with 1997, and would have
increased by five percent for 1997 compared to 1996. The sales decrease in the
Space & Strategic Missiles segment in 1998 would have been offset by sales
increases for the other business segments, after adjusting for divestiture
activities. Sales increases in 1997 in the Space & Strategic Missiles,
Aeronautics and Information & Services segments, as well as the inclusion of the
operations of the businesses acquired in connection with the Loral Transaction
for a full year in 1997 versus nine months in 1996, more than offset the
reduction in sales due to divested operations. The U.S. Government remained the
Corporation's largest customer, comprising approximately 70 percent of the
Corporation's net sales for 1998 compared to 66 percent in 1997 and 70 percent
in 1996.

     The Corporation's operating profit (earnings before interest and taxes) for
1998 was approximately $2.5 billion, a decrease of nine percent compared to
1997. Operating profit for 1997 was $2.8 billion, a two percent increase
compared to 1996. The reported amounts for the three years presented include the
financial impacts of various nonrecurring and unusual items, the details of
which are

- --------------------------------------------------------------------------------
described below. Excluding the effects of these nonrecurring and unusual items
for each year, operating profit for 1998 would have decreased by six percent
compared to 1997, and would have increased by nine percent in 1997 compared to
1996. For 1998 compared to 1997, decreases in operating profit at the Space &
Strategic Missiles and Information & Services segments more than offset the
increase in operating profit at the Electronics segment. For 1997 compared to
1996, increases in operating profits at the Space & Strategic Missiles and
Aeronautics segments more than offset a reduction in operating profit at the
Information & Services segment. For a more detailed discussion of the operating
results of the business segments, see "Discussion of Business Segments" below.

     Operating profit in 1998 included the effects of a nonrecurring and unusual
pretax charge, net of state income tax benefits, totaling $233 million related
to CalComp Technology, Inc. (CalComp), a majority-owned subsidiary of the
Corporation. In the fourth quarter of 1998, the Corporation decided that it
would not increase existing credit for CalComp to support ongoing operations,
and agreed to provide financing, subject to certain conditions, for a plan
providing for the timely non-bankruptcy shutdown of CalComp's business. The
above actions resulted in a charge related to the impairment of assets and
estimated costs required to accomplish the shutdown of CalComp's operations.

(a)  Excluding the effects of the Materials exchange, the divestiture of two
     business units, and the charges associated with the environmental
     remediation business, impairment in values for certain assets, and other
     costs, 1996 net earnings would have been $1,205 million.

(b)  Reflects the business combination with Loral Corporation since April 1996.

(c)  Excluding the effects of the gain on the transaction with GE, and the
     charges related to the Corporation's decision to exit certain lines of
     business and impairment in values for certain assets, 1997 net earnings
     would have been $1,292 million.

(d)  Excluding the effects of a nonrecurring and unusual charge related to
     CalComp, 1998 net earnings would have been $1,184 million.

'98                 $ 2.63
'98/(e)/            $ 3.11

(a)  Excluding the effects of the Materials exchange, the divestiture of two
     business units, and the charges associated with the environmental
     remediation business, impairment in values for certain assets, and other
     costs, 1996 diluted earnings per share would have been $2.72.

(b)  Reflects the business combination with Loral Corporation since April 1996.

(c)  Includes the effects of a deemed preferred stock dividend in determining
     net loss applicable to common stock in the computation of loss per share
     which resulted from the GE Transaction. The effect of this deemed dividend
     was to reduce the diluted per share amount by $4.93.

(d)  Excluding the effects of the deemed preferred stock dividend, the gain on
     the transaction with GE, and the charges related to the Corporation's
     decision to exit certain lines of business and impairment in values for
     certain assets, and including the dilutive effects of preferred stock
     conversion and stock options, 1997 diluted earnings per share would have
     been $3.02.

(e)  Excluding the effects of a nonrecurring and unusual charge related to
     CalComp, 1998 diluted earnings per share would have been $3.11.


     During the fourth quarter of 1997, in addition to recording the tax-free
gain resulting from the GE Transaction, the Corporation recorded nonrecurring
and unusual pretax charges, net of state income tax benefits, totaling $457
million. These charges related to the Corporation's decision to exit certain
lines of business and related to impairment in the values of various non-core
investments and certain other assets.

     Operating profit in 1996 included the gain on the Materials exchange. In
addition, during the fourth quarter of 1996, the Corporation recorded
nonrecurring pretax charges, net of state income tax benefits, of $307 million.
These charges related to the Corporation's environmental remediation business,
and related to impairment in the values of non-core investments and certain
other assets, and costs for facility closings and transfers of programs.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
AND RESULTS OF OPERATIONS (Continued)
December 31, 1998

     The Corporation's reported net earnings for 1998 were $1.0 billion, a
decrease of 23 percent compared to 1997. Reported net earnings for 1997 were
$1.30 billion, a decrease of three percent compared to the reported 1996 net
earnings of $1.35 billion. The 1998 reported amount includes the after-tax
effect of the CalComp nonrecurring and unusual charge, which decreased net
earnings by $183 million, or $.48 per diluted share. The 1997 reported amount
includes the tax-free gain resulting from the GE Transaction of $311 million,
and the after-tax effects of the nonrecurring and unusual charges described
above of $303 million which, on a combined basis, decreased the 1997 diluted
loss per share by $.02. The 1996 reported amounts include the after-tax effects
of the Materials exchange and the provision for the after-tax effect of the
Corporation's divestiture of its Armament Systems and Defense Systems business
units. On a combined basis, these transactions increased 1996 net earnings by
$351 million. The 1996 reported amounts also include the after-tax impact of the
nonrecurring charges described above, which decreased net earnings by $209
million. These nonrecurring and unusual items increased 1996 diluted earnings
per share by $.32 on a combined basis. Excluding the effects of these
nonrecurring and unusual items, net earnings for 1998, 1997 and 1996 would have
been approximately $1.18 billion, $1.29 billion and $1.20 billion, respectively.

     The Corporation reported diluted earnings (loss) per share of $2.63,
$(1.56) and $3.04 for 1998, 1997 and 1996, respectively. For purposes of
determining 1997 net loss applicable to common stock used in the computation of
loss per share, the excess fair value of assets transferred to GE over the
carrying value of the preferred stock (approximately $1.8 billion) was treated
as a deemed preferred stock dividend and deducted from 1997 net earnings. This
deemed dividend had a significant impact on the 1997 loss per share
calculations, but did not impact reported 1997 net earnings. The effect of this
deemed dividend was to reduce the basic and diluted per share amounts by $4.93.
If the nonrecurring and unusual items described above were excluded from the
calculation of earnings per share and, for 1997, if the dilutive effects of
preferred stock conversion and stock options were factored into the diluted
earnings per share calculation, diluted earnings per share for 1998, 1997 and
1996 would have been $3.11, $3.02 and $2.72, respectively.

     The Corporation's debt to capitalization ratio improved from 70 percent at
year-end 1997 to 64 percent at December 31, 1998. Total debt (including
short-term borrowings) at December 31, 1998 decreased to $10.9 billion from
$11.9 billion at year-end 1997. Total stockholders' equity increased to $6.1
billion at December 31, 1998 from $5.2 billion at year-end 1997. The Corporation
paid dividends of $310 million in 1998, or $.82 per common share. 

Industry Considerations 

The Corporation's primary lines of business are in advanced
technology systems for aerospace and defense, serving both government and
commercial customers. In recent years, domestic and worldwide political and
economic developments have strongly affected these markets, requiring
significant adaptation by market participants.
 
     The U.S. aerospace and defense industry has experienced years of declining
budgets for research, development, test and evaluation, and procurement.
Currently, after 14 years of continuous declines in the U.S. defense budget,
expenditures (after adjusting for inflation) are at their lowest point since
before World War II. The portion of the Federal budget devoted to defense is at
its lowest percentage in modern history. The industry participants' reaction to
the shrinking budgets has been to combine to maintain critical mass and achieve
significant cost savings.

     The U.S. Government had been supportive of industry consolidation
activities through 1997, and the Corporation had been at the forefront of these
activities. Through its own consolidation activities, the Corporation has been
able to pass along savings to its customers, principally the U.S. Department of
Defense. Though new consolidation activities among the large U.S. aerospace and
defense companies have declined recently, the much anticipated consolidation of
the European defense industry may be starting. In January 1999, British
Aerospace P.L.C. announced that it intends to purchase the Marconi Electronics
unit of General Electric Company P.L.C. of Great Britain.

     With the decline of significant domestic industry consolidation, major
aerospace companies will need to focus on cost savings and efficiency
improvements. The Corporation has already focused on cutting costs, raising
productivity, and capitalizing on synergies and best practices which should
improve its competitiveness in the future.
 
     There are now signs that the continuing declines in the defense budget may
have ended, with proposals being made for modest increases in the next several
years. The Corporation's broad mix of programs and capabilities makes it a
likely beneficiary of increased defense spending.
 
     As a government contractor, the Corporation is subject to U.S. Government
oversight. The government may investigate and make inquiries of the
Corporation's business practices and conduct audits of contract performance and
cost accounting. These investigations may lead to claims against the
Corporation. Under U.S. Government procurement regulations and practices, an
indictment of a government contractor could result in that contractor being
fined and/or

suspended for a period of time from eligibility for bidding on, or for award of,
new government contracts. A conviction could result in debarment for a specified
period of time. Similar government oversight exists in most other countries
where the Corporation conducts business. Although the outcome of such
investigations and inquiries cannot be predicted, in the opinion of management,
there are no claims, audits or investigations pending against the Corporation
that are likely to have a material adverse effect on the Corporation's business
or its consolidated results of operations, cash flows or financial position.

     The Corporation remains exposed to other inherent risks associated with
U.S. Government contracting, including technological uncertainties and
obsolescence, changes in government policies and dependence on annual
Congressional appropriation and allotment of funds. Many of the Corporation's
programs involve development and application of state-of-the-art technology
aimed at achieving challenging goals. As a result, setbacks and failures can
occur. In 1998, for example, the Corporation experienced difficulties related to
its Theater High Altitude Area Defense (THAAD) system and commercial space
programs. It is important for the Corporation to resolve the related performance
issues to achieve success on these programs.

     The Corporation continues to focus on expanding its presence in related
commercial and non-defense markets, most notably in space and telecommunications
activities, information management and systems integration. Although these lines
of business are not dependent on defense budgets, they share many of the risks
associated with the Corporation's primary businesses, as well as others unique
to the commercial marketplace. Such risks include development of competing
products, technological feasibility and product obsolescence. The
telecommunications market is expected to double over the next five years.
Although the Corporation has limited experience and sales in this market as of
the end of 1998, the Corporation hopes to apply its technological capabilities
and the benefits of the merger with COMSAT, if consummated, to meet the
increasing demand for broadband, Internet and virtual network services.

     In connection with expanding its portfolio of offered products and services
in commercial space and telecommunications activities, the Corporation has
entered into various joint venture, teaming and other business arrangements,
including some with foreign partners. The conduct of international business
introduces other risks into the Corporation's operations, including fluctuating
economic conditions, fluctuations in relative currency values and the potential
for unanticipated cost increases and timing issues resulting from the
deterioration of political relations.

     In 1992, the Corporation entered into a joint venture with two Russian
government-owned space firms to form Lockheed-Khrunichev-Energia International,
Inc. (LKEI). Lockheed Martin owns 51% of LKEI and consolidates the operations of
LKEI into its financial statements. LKEI has exclusive rights to market launches
of commercial, non-Russian-origin payloads to space on the Proton rocket from a
launch site in Kazakhstan. In 1995, another joint venture was formed,
International Launch Services (ILS), with the Corporation and LKEI each holding
50 percent ownership. ILS was formed to market commercial Atlas and Proton
launch services worldwide. Contracts for Proton launch services typically
require substantial advances from the customer in advance of launch, and a
sizable percentage of these advances are forwarded to Khrunichev State Research
and Production Space Center (Khrunichev), the manufacturer in Russia, to provide
for the manufacture of the related launch vehicle. Significant portions of such
advances would be required to be refunded to each customer if launch services
were not successfully provided within the contracted time frame. At December 31,
1998, approximately $990 million related to launches not yet provided was
included in customer advances and amounts in excess of costs incurred, and
approximately $740 million of payments to Khrunichev for launches not yet
provided was included in inventories. Through year end 1998, launch services
provided through LKEI and ILS have been in accordance with contract terms.

     An additional risk exists related to launch vehicle services in Russia.
Under a trade agreement in effect since September 1993 between the United States
and Russia, the number of Russian launches of U.S. built satellites into
geosynchronous and geosynchronous transfer orbit is limited to fifteen from
trade agreement inception through the year 2000. Officials of the U.S.
Government have stated that this limit will not be raised until Russia takes
satisfactory action to resolve missile technology proliferation concerns. This
limit, if not raised or eliminated, could impair the Corporation's ability to
achieve certain of its business objectives related to launch services, satellite
manufacture and telecommunications market penetration. At December 31, 1998,
approximately $375 million of the $990 million of customer advances and
approximately $280 million of the $740 million of payments to Khrunichev
disclosed in the prior paragraph are associated with launches in excess of the
number currently allowed under the quota. Management is working to achieve a
favorable resolution to raise or eliminate the limitation on the number of
Russian launches.

     The Corporation has entered into agreements with RD AMROSS, a joint venture
of the Pratt & Whitney division of United Technologies Corporation and the
Russian firm NPO Energomash, for the development and purchase, subject to
certain conditions, of up to 101 RD-180 booster engines for use in two models of
the Corporation's launch vehicles. Terms of the agreements call for payments to
be made to RD AMROSS upon the achievement of certain milestones in the
development and manufacturing processes. Approximately $100 million of payments
made under these agreements were included in the Corporation's inventories at
December 31, 1998.

Discussion of Business Segments 

The Corporation's operations are divided into five business segments: Space &
Strategic Missiles; Electronics; Aeronautics; Information & Services; and Energy
and Other. Effective January 1, 1998, management responsibility for United Space
Alliance, a limited liability company owned by the Corporation and The Boeing
Company, was reassigned from the Information & Services segment to the Space &
Strategic Missiles segment. Management reporting of certain other activities was
also reassigned among the Space & Strategic Missiles, Electronics, and Energy
and Other segments. Consequently, 1997 and 1996 operating profit amounts for
these segments have been restated to conform with the 1998 presentation.

</TABLE> 

     In an effort to make the following discussion of significant operating
results of each business segment more understandable, the effects of these
nonrecurring and unusual items discussed earlier have been excluded. The Space &
Strategic Missiles and Aeronautics segments generally include programs that are
substantially larger in terms of sales and operating profits than those included
in the other segments. Accordingly, due to the significant number of smaller
programs in the Electronics and Information & Services segments, the impacts of
performance on individual programs typically are not as material to these
segments' results of operations.

Space & Strategic Missiles

Net sales of the Space & Strategic Missiles segment decreased by 10 percent in
1998 compared to 1997 and increased by five percent in 1997 compared to 1996.
The segment's 1998 net sales activity was adversely impacted by reductions in
Atlas and Proton commercial launch vehicle activities, primarily as a result of
delays in availability of commercial satellites due to supplier issues, a
reduction in volume on the Trident fleet ballistic missile program, and a
decrease in volume in classified program activities. During 1997, increases in
Proton launch services volume and additional revenues from commercial satellite
programs contributed roughly equally to the segment's growth as compared to
1996.

     Operating profit for the segment decreased by 17 percent in 1998 compared
to 1997 after having increased by 19 percent for 1997 compared to 1996. The 1998
decrease resulted from the same issues that impacted net sales, as discussed
above, as well as from losses and performance related charges totaling
approximately $100 million in the commercial space product areas. This decrease
was partially offset by a third quarter favorable adjustment of approximately
$128 million, which resulted from a significant improvement in the Atlas launch
vehicle program related to the retirement of program and technical risk based
upon a current evaluation of the program's historical performance, and
approximately $50 million related to the favorable impact of the restructure of
a commercial satellite program which occurred in the fourth quarter. The 1997
increase resulted equally from improved margins on Atlas launches and the
increase in Proton launch activity mentioned previously. 

Electronics 

The Electronics segment's net sales increased by four percent in 1998 compared
to 1997, and by six percent in 1997 compared to 1996. Excluding the operations
of the segment's Commercial Electronics unit, which was divested during the
first quarter of 1998, net sales in 1998 would have increased by eight percent
from 1997. Nearly $200 million of the increase in 1998 resulted from greater
production deliveries of postal systems equipment and, to a lesser extent, net
sales were favorably impacted by increases in surface ship systems and control
systems activities in 1998. Net sales for 1997 included a full year of the
operations of certain businesses acquired in connection with the Loral
Transaction versus nine months in 1996, offset by the absence of sales in 1997
resulting from the divestiture of the Corporation's Armament Systems and Defense
Systems businesses. Adjusting the results of operations to reflect these
companies on a comparable basis, 1997 net sales would have decreased by two
percent compared to 1996.

     Operating profit for the segment increased by 14 percent in 1998 compared
to 1997, following a four percent decrease in 1997 compared to 1996. Adjusting
the results of operations to reflect the items previously mentioned on a
comparable basis, operating profit would have increased by 14 percent in 1998
compared to 1997, and decreased by 10 percent in 1997 compared to 1996. During
1998, operating profit increased primarily due to improved margins on electronic
defense systems and, to a lesser extent, the volume increases that impacted net
sales as discussed above. During 1997, operating profit decreased as a result of
investments in new programs as well as reduced margins for the Commercial
Electronics unit.

- --------------------------------------------------------------------------------
Aeronautics

Net sales of the Aeronautics segment decreased by one percent in 1998 compared
to 1997, after having increased by eight percent in 1997 compared to 1996.
Excluding the operations of the segment's Aerostructures business unit divested
to GE during the fourth quarter of 1997, net sales would have increased by three
percent during 1998 primarily due to increased volume related to F-16 fighter
aircraft and other modification, maintenance and logistic programs. The 1997
increase principally resulted from increased deliveries of F-16 fighter aircraft
from the prior year. 

     Operating profit for the segment remained relatively stable during 1998
compared to 1997, and increased by 35 percent in 1997 compared to 1996.
Excluding the operations of the Aerostructures business unit, operating profit
would have increased by 10 percent in 1998 compared to 1997, and by 33 percent
in 1997 compared to 1996. Operating profit increased during 1998 primarily as a
result of increased F-16 aircraft deliveries and improved performance on
tactical aircraft programs. During 1997, operating profit increased due to the
greater number of F-16 deliveries, and the completion of significant flight
performance milestone events and margin improvements on the C-130 program.

Information & Services

Net sales of the Information & Services segment decreased by 19 percent in 1998
compared to 1997, and increased by 10 percent in 1997 compared to 1996. The
decrease in 1998 reflects the absence of the results of operations of the
segment's Access Graphics business unit, divested to GE in the fourth quarter of
1997, and the operations of L-3, which were divested effective March 30, 1997.
Excluding the impact of these divestitures, the segment's net sales for 1998
would have increased by three percent compared to 1997. Approximately $200
million of this increase resulted from higher sales volume in certain technology
services programs and welfare and family services programs, partially offset by
a reduction in sales due to performance issues in the commercial products
businesses. The 1997 net sales increase reflected a $300 million increase in
sales volume related to commercial products, system integration programs and
information systems programs. The inclusion of a full year of the operations of
certain businesses acquired in connection with the Loral Transaction in 1997
versus nine months in 1996 was largely offset by the effect of the absence of
L-3 operations and the Corporation's transfer of its Space Shuttle processing
operations to United Space Alliance.

  Operating profit for the segment decreased by 24 percent in 1998 compared to
1997, and by 27 percent in 1997 compared to 1996. Adjusting the 1997 and 1996
results of operations for the items discussed in the preceding paragraph on a
comparable basis, operating profit for 1998 would have decreased by 22 percent
compared to 1997, and by 23 percent in 1997 compared to 1996. The operating
profit decrease for 1998 resulted from the impact of the performance issues in
the commercial products businesses and the timing of recognition of performance
improvements in certain systems integration programs in 1997. The 1997 decrease
resulted from unfavorable performance in the segment's commercial product
businesses, primarily CalComp. As disclosed previously, CalComp is conducting a
timely non-bankruptcy shutdown of its operations. 

Energy and Other 

Net sales of the Energy and Other segment increased by 39 percent in 1998
compared to 1997 after having decreased significantly in 1997 compared to 1996.
The 1998 increase primarily reflects additional sales volume in environmental
activities. The net sales decrease in 1997 principally resulted from the
divestiture of Materials during the fourth quarter of 1996.

     Operating profit for this segment increased by 10 percent in 1998 compared
to 1997, and by 18 percent in 1997 compared to 1996. In both years, improvements
in the Corporation's performance on certain environmental programs were
realized, and additional gains were recognized on land sales of $16 million in
1998 compared to 1997 and $20 million in 1997 compared to 1996. Operating profit
in 1997 was also negatively impacted by the absence of the results of operations
of Materials.

principally from contract modifications to the Titan IV program. During 1998,
the Corporation entered into an agreement with the U.S. Government that provides
$500 million of funding to develop the Evolved Expendable Launch Vehicle. The
Corporation will use its best efforts to design a prototype to comply with the
launch capability requirements included in the agreement. Since this agreement
does not constitute a procurement contract, funding has been excluded from
backlog. The decrease in 1997 resulted principally from a reduction in
classified backlog and a finalization of the Corporation's backlog recognition
policy for the SBIRS program.

     Total Electronics segment backlog increased by eight percent in 1998
compared to 1997, after having decreased by eight percent in 1997 compared to
1996. During 1998, backlog increased primarily as a result of new orders
received for various surface ship systems and missile systems activities. The
1997 decrease was caused by absence of backlog related to the Armament Systems
and Defense Systems businesses divested during 1997.

     Total Aeronautics segment backlog decreased by 21 percent in 1998 compared
to 1997 after having increased slightly in 1997 compared to 1996. The segment's
1998 backlog was impacted by a significant decrease in new order activity from
the prior year, principally related to the timing of new orders. Specifically,
during 1998, the government of the United Arab Emirates selected the
Corporation's F-16 as its advanced fighter aircraft. The Corporation is working
to secure a definitive contract, estimated to be worth over $5 billion, during
1999. In 1997, new orders for C-130 airlift aircraft were offset by the
reduction in F-16 fighter aircraft backlog and the divestiture of the segment's
Aerostructures business backlog to GE.

     Total Information & Services backlog increased by 16 percent in 1998
compared to 1997, after having decreased slightly in 1997 compared to 1996. The
increase from 1997 to 1998 related to the 1998 award to the Corporation of the
Consolidated Space Operations Contract by the National Aeronautics and Space
Administration, and increases related to the receipt of new information
management services contract awards. The decrease in 1997 resulted from the
absence of backlog related to the companies that were divested to L-3 during
1997.

Liquidity and Cash Flows

Operating Activities

Operating activities provided $2.0 billion in cash during 1998, compared to $1.2
billion and $1.6 billion provided in 1997 and 1996, respectively. The
significant increase in cash provided by operations during 1998 was a result of
improved operating cash flow and reduced net Federal income tax payments.

Investing Activities

The Corporation used $455 million in cash for investing activities during 1998,
compared to $185 million provided during 1997 and $8.0 billion used during 1996.
For the three years presented, the major investments of cash were related to
property, plant and equipment additions, which declined 7 percent in 1998 after
a 2 percent increase in 1997. During 1998, $134 million of net cash was provided
by divestiture and acquisition activities. During 1997, cash was principally
provided by the disposition of the Armament Systems and Defense Systems
businesses and the divestiture of L-3. During 1996, the Corporation used $7.3
billion of cash to finance the Loral Transaction. 

Financing Activities 

The Corporation used $1.3 billion in cash for financing activities during 1998,
compared to $1.4 billion used during 1997 and $5.7 billion provided during 1996.
Because operating activities generated significantly more cash during 1998, the
Corporation was able to reduce its total debt by more than $1.0 billion. During
1997, the Corporation also was able to decrease its short-term borrowings
significantly, while long-term debt borrowings were increased to finance the GE
Transaction. During 1996, $7.6 billion in cash was provided through an increase
in indebtedness to finance the Loral Transaction. Approximately $886 million of
long-term debt will mature in 1999.

     During 1998, the Corporation paid $310 million in common stock dividends,
compared to $299 million and $302 million during 1997 and 1996, respectively.
During the third quarter of 1998, the Corporation's Board of Directors approved
an increase to the cash dividend per share of common stock to $.22 per share, or
$.88 annually, on a post stock split basis. The increased dividend was effective
for dividends declared in the fourth quarter of 1998.

Other 

The Corporation receives advances on certain contracts to finance inventories.
At December 31, 1998, approximately $2.5 billion in advances related to work in
process were received from customers and recorded as a reduction to inventories
in the Corporation's consolidated balance sheet. In addition, customer advances
(typically from foreign governments and commercial customers) were approximately
$4.0 billion at the end of 1998. The Corporation maintains these amounts as
current liabilities.

- --------------------------------------------------------------------------------
Capital Structure and Resources

Total debt, including short-term borrowings, decreased by more than $1.0 billion
during 1998 from approximately $11.9 billion at December 31, 1997. This decrease
was comprised of net short-term debt repayments of $151 million and the net
repayment of long-term debt of $870 million. The Corporation's long-term debt is
primarily in the form of publicly issued, fixed-rate Notes and Debentures. At
year end 1998, the Corporation held cash and cash equivalents of $285 million,
which were used to pay down its commercial paper borrowings in January 1999.
Total stockholders' equity was $6.1 billion at December 31, 1998, an increase of
nearly $1 billion from the December 31, 1997 balance. This increase principally
resulted from 1998 net earnings. Consequently, the Corporation's total debt to
capitalization ratio improved from 70 percent at December 31, 1997 to 64 percent
at December 31, 1998.

     At the end of 1998, the Corporation had in place a short-term revolving
credit facility in the amount of $2.5 billion which matures on May 28, 1999, and
a long-term revolving credit facility in the amount of $3.5 billion, which
matures on December 20, 2001 (collectively, the Credit Facilities). No
borrowings were outstanding under the Credit Facilities at December 31, 1998.
However, the Credit Facilities support commercial paper borrowings of
approximately $1.3 billion outstanding at December 31, 1998. Based on
management's ability and intention to maintain this amount of debt outstanding
for at least one year, $300 million of this amount has been classified as
long-term debt.

     The Corporation has entered into standby letter of credit agreements and
other arrangements with financial institutions primarily relating to the
guarantee of future performance on certain contracts. At December 31, 1998, the
Corporation had contingent liabilities on outstanding letters of credit,
guarantees and other arrangements aggregating approximately $1.3 billion. 

     In January 1999, the Corporation filed a shelf registration with the
Securities and Exchange Commission to provide for the issuance of up to $2.5
billion in debt securities. The registration statement is expected to be
declared effective in the first quarter of 1999. 

     The Corporation actively seeks to finance its business in a manner that
preserves financial flexibility while minimizing borrowing costs to the extent
practicable. The Corporation's management continually reviews the changing
financial, market and economic conditions to manage the types, amounts and
maturities of the Corporation's indebtedness. Periodically, the Corporation may
refinance existing indebtedness, vary its mix of variable rate and fixed rate
debt and the maturities of that debt, or seek alternative financing sources for
its cash and operational needs. As a result of the proposed COMSAT transaction,
the Corporation's senior long-term debt rating is currently under review by one
rating agency.

     Cash and cash equivalents including temporary investments, internally
generated cash flow from operations and other available financing resources are
expected to be sufficient to meet anticipated operating, capital expenditure and
debt service requirements and discretionary investment needs during the next
twelve months. Consistent with the Corporation's desire to generate cash to
invest in its core businesses and reduce debt, management anticipates that,
subject to prevailing financial, market and economic conditions, the Corporation
may continue to divest certain non-core businesses, passive equity investments
and surplus properties.

Year 2000 Issues

Like most companies, Lockheed Martin is affected by Year 2000 issues.
Accordingly, all of the Corporation's business units are actively involved in
its Year 2000 Compliance Program (the Program). The Program has been designed to
minimize risk to the Corporation's business units and its customers using a
standard six-phase industry approach. The six phases include: Awareness,
Assessment, Renovation, Validation, Implementation and Post-Implementation. In
the Awareness phase, the problem is defined, risks and magnitude of repairs are
communicated, and executive level support and sponsorship is obtained. During
the Assessment phase, an inventory of assets that could be impacted by Year 2000
compliance issues is prepared which includes internal information technology
(IT) systems (e.g. hardware, program applications, data centers), external IT
systems (e.g. customer products and deliverables, interfaces with third parties)
and non-IT systems (e.g. facilities, non-IT equipment).

     In the Renovation phase, a plan for remediation is developed for each
system or product based on its critical nature and risk. Renovation is
considered complete when these plans have been implemented and the actual
conversion of the hardware, firmware or software has occurred. Renovation of
customer products and deliverables, where requested and funded by the customer,
is also a part of this phase. The Validation phase involves testing of all
renovated systems to ensure that they will operate correctly across and during
the new millennium. During the Implementation phase, renovated and validated
systems are placed into live production environments. The Post-Implementation
phase occurs in the Year 2000. This phase will entail monitoring of systems to
ensure Year 2000 compliance and implementing business continuity and contingency
plans as considered necessary.

     Lockheed Martin's Program was designed to achieve the Corporation's overall
goal of Year 2000 readiness in advance of the century change. The Corporation
views Year 2000 awareness as a continuous phase of the Program that has resulted
in distribution of news letters, development of internal and external web sites
and an internal Year 2000 Awareness Week. During 1998, the Assessment phase was
completed. As of December 31, 1998, the Renovation phase was approximately 95
percent complete, and the Validation and Implementation phases were both
approximately 80 percent complete. The year 1999 will be used to complete the
remaining phases of the Program, as appropriate, which will include addressing
late availability of vendor or government furnished equipment, monitoring the
status of Year 2000 compliance of vendors and customers (related to both
products and readiness), completing planned replacement of systems, and
developing contingency and crisis management plans as deemed necessary.
Management estimates that the Renovation phase will be completed in the first
quarter of 1999, and that both the Validation and Implementation phases will be
completed in the second quarter of 1999, with few exceptions that include
planned new and contingency implementations.

     Management currently estimates that total costs of the Program will be
approximately $85 million, 60 percent of which had been expended through
December 31, 1998. These costs have not been material to the Corporation's
consolidated results of operations, cash flows or financial position for any
prior period and, based on information available at this time, are not expected
to be material in

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
AND RESULTS OF OPERATIONS (Continued)

- --------------------------------------------------------------------------------
any future period. The remaining costs are expected to be directed primarily
toward validation testing and implementation activities. These estimates include
internal costs as well as costs for outside consulting services, but do not
include estimated costs for system replacements which were not accelerated due
to Year 2000 issues. No significant IT projects have been deferred due to Year
2000 efforts. The costs incurred for the Program are allowable in establishing
prices for the Corporation's products and services under contracts with the U.S.
Government. Therefore, a substantial portion of these costs are being reflected
in the Corporation's sales and cost of sales.

     The costs to implement and the time frame contemplated by the Program are
based on management's estimates, which were derived utilizing numerous
assumptions related to future events, including each vendor's ability to modify
proprietary software, the ability of other third parties (including domestic and
foreign customers and suppliers) to successfully address their Year 2000 issues,
unanticipated issues identified in executing the Program and other similar
uncertainties. While the Corporation expects to resolve all Year 2000 risks
without a material adverse impact to its consolidated results of operations,
cash flows or financial position, there can be no guarantee that these estimates
of costs or timing, or that the objectives of the Program, will be achieved. To
mitigate these risks, the Corporation has formal measurement and reporting
processes in place. For example, internal auditors meet weekly with Program
personnel to review the current status of the Program and related issues, and
Program reviews are conducted monthly with each of the Corporation's segments
and quarterly at the business unit level. In addition, updates are presented
periodically to executive management, the Board of Directors and the Audit and
Ethics Committee. The Corporation has obtained additional assurance through the
use of internal independent test environments, third party verification of
randomly selected renovated and validated applications, and internal audits
designed to ensure Year 2000 readiness. Program assessments have been conducted
by customers and the Defense Contract Audit Agency throughout the Program. With
respect to third parties, the Corporation is aware that a number of its domestic
and foreign key suppliers and customers have just recently begun to aggressively
address their Year 2000 issues and, therefore, believes there is risk associated
with their achieving timely Year 2000 compliance. To mitigate this risk, formal
communication with all of our key suppliers and customers (including banks and
U.S. Government customers) has been initiated as part of the Program. In
response to this communication, the Corporation has received differing levels of
information from these third parties to assist in the assessment of their Year
2000 readiness; however, in most cases, the Corporation is unable to verify the
accuracy of their responses. Based on information available at this time,
management believes that Program activities to date are consistent with the
Program's design.

     The Corporation is aware that a "reasonably likely worst case" scenario of
Year 2000 risks could include isolated interruption of deliveries from critical
domestic and foreign suppliers, the inability of critical domestic and foreign
customers to conduct business due to disruption of their operations, product
liability issues, isolated performance problems with manufacturing or
administrative systems, and late availability of embedded vendor products for
which responsibility for Year 2000 compliance rests with the respective vendor.
The consequences of these issues may include increases in manufacturing and
general and administrative expenses until the issues are resolved, lost
revenues, lower or delayed cash receipts, and product liability. The Corporation
cannot currently quantify the potential effect of these issues on its
consolidated results of operations, cash flows or financial position, should
some or a combination of these events come to pass. However, based on
information available at this time, management believes that activities of the
Program designed to mitigate these types of issues are consistent with the
Program's design.

     The Corporation requires assessments of risk throughout Program execution.
Business continuity planning is underway and will continue through 1999 to
address risk associated with interruption to key business areas. In connection
with these assessments, Lockheed Martin has developed guidelines for when
contingency plans are required and a standard template for use in documenting
such plans. For example, contingency plans are required for any work that is
scheduled to be completed after mid-1999, where there is significant risk of
domestic or foreign supplier chain disruption, or for a new system
implementation where schedule or technical issues are assessed to be
significantly at risk, in which case renovation of legacy systems has been or
will be performed. Additionally, while management believes that most of the
Corporation's non-IT systems will function without substantial compliance
problems, preparation for events that are generally outside the direct control
of the Corporation (e.g. loss of power or telecommunication capabilities) have
been included as part of crisis management planning. The Corporation's plans
include coordination with existing emergency or crisis management teams within
our facilities to ensure that scenarios are utilized in training and drills
during 1999.

Environmental Matters 

As more fully described in Note 16 to the consolidated financial statements, the
Corporation has entered into two consent decrees with the U.S. Environmental
Protection Agency (EPA) relating to certain property in Burbank, California, and
is operating under a cleanup and abatement order from the California Regional
Water Quality Control Board (the Regional Board) regarding its Burbank
facilities. The Corporation estimates that total expenditures required over the
remaining terms of the consent decrees and the Regional Board order related to
the Burbank property will be approximately $110 million. In addition, the
Corporation is responding to three administrative orders issued by the Regional
Board in connection with its facilities in Redlands, California. The Corporation
estimates that expenditures required to implement work currently approved by the
Regional Board related to the Redlands facilities will be approximately $110
million. Also in connection with its Redlands facilities, the Corporation is
coordinating with the U.S. Air Force, which is conducting studies of the
potential health effects of exposure to perchlorates, a regional groundwater
contaminant. The results of these studies indicate that the Corporation's
current efforts with water purveyors regarding perchlorate issues are
appropriate; however, the Corporation currently cannot project the extent of its
ultimate clean-up obligation with respect to perchlorates, if any.

                                                     Lockheed Martin Corporation



- --------------------------------------------------------------------------------
     The Corporation is a party to various other proceedings and potential
proceedings related to environmental clean-up issues, including matters at
various sites where it has been designated a Potentially Responsible Party (PRP)
by the EPA or by a state agency. In the event the Corporation is ultimately
found to have liability at those sites where it has been designated a PRP, the
Corporation anticipates that the actual burden for the costs of remediation will
be shared with other liable PRPs. Generally, PRPs that are ultimately determined
to be responsible parties are strictly liable for site clean-ups and usually
agree among themselves to share, on an allocated basis, the costs and expenses
for investigation and remediation of hazardous materials. Under existing
environmental laws, however, responsible parties are jointly and severally
liable and, therefore, the Corporation is potentially liable for the full cost
of funding such remediation. In the unlikely event that the Corporation were
required to fund the entire cost of such remediation, the statutory framework
provides that the Corporation may pursue rights of contribution from the other
PRPs. Among the variables management must assess in evaluating costs associated
with these sites are changing cost estimates, continually evolving governmental
environmental standards and cost allowability issues. Therefore, the nature of
these environmental matters makes it extremely difficult to estimate the timing
and amount of any future costs that may be necessary for remedial actions.

     The Corporation records appropriate financial statement accruals for
environmental issues in the period in which it is probable that a liability has
been incurred and the amounts can be reasonably estimated. In addition to the
matters with respect to the Burbank and Redlands properties described above, the
Corporation has accrued approximately $240 million at December 31, 1998 for
other matters in which an estimate of financial exposure could be determined.
Management believes, however, that it is unlikely that any additional liability
the Corporation may incur for known environmental issues would have a material
adverse effect on its consolidated results of operations or financial position.

     Also as more fully described in Note 16, the Corporation is continuing to
pursue recovery of a significant portion of the unanticipated costs incurred in
connection with the $180 million fixed price contract with the U.S. Department
of Energy (DOE) for the remediation of waste found in Pit 9, located on the
Idaho National Engineering and Environmental Laboratory reservation. The
Corporation has been unsuccessful to date in reaching any agreements with the
DOE on cost recovery or other contract restructuring matters. In June 1998, the
DOE, through Lockheed Martin Idaho Technologies Company (LMITCO), the DOE's
management contractor on the Pit 9 project, terminated the Pit 9 contract for
default. On the same date, the Corporation filed a lawsuit against the DOE in
the U.S. Court of Federal Claims challenging and seeking to overturn the default
termination. In July 1998, the Corporation withdrew the request for equitable
adjustment (REA) it had submitted previously and replaced it with a certified
REA. This action raised the status of the REA to a formal claim. In August 1998,
LMITCO, at the DOE's direction, filed suit against the Corporation in U.S.
District Court in Idaho, seeking recovery of approximately $54 million
previously paid by LMITCO to the Corporation under the Pit 9 contract. In
January 1999, the U.S. District Court in Idaho granted the Corporation's motion
and stayed the Idaho proceeding until resolution of the motion to dismiss the
lawsuit in the U.S. Court of Federal Claims, or until August 2, 1999. The
Corporation continues to assert its position in the litigation while continuing
efforts to resolve the dispute through non-litigation means. 

Other Matters 

The Corporation uses forward exchange contracts to manage its exposure to
fluctuations in foreign exchange rates. These contracts are designated as
qualifying hedges of firm commitments or specific anticipated transactions, and
related gains and losses on the contracts are recognized in income when the
hedged transaction occurs. At December 31, 1998, the amounts of forward exchange
contracts outstanding, as well as the amounts of gains and losses recorded
during the year, were not material. The Corporation does not hold or issue
derivative financial instruments for trading purposes.

     The Corporation will adopt the American Institute of Certified Public
Accountants' Statement of Position (SOP) No. 98-5, "Reporting on the Costs of
Start-Up Activities" effective January 1, 1999. This SOP requires that, at the
effective date of adoption, costs of start-up activities previously capitalized,
primarily in inventories, be expensed and reported as a cumulative effect of a
change in accounting principle, and further requires that such costs subsequent
to adoption be expensed as incurred. Management estimates that the amount of the
cumulative effect adjustment to be recognized upon the adoption of SOP No. 98-5,
net of income tax benefits of approximately $230 million, will be approximately
$350 million.

THE CORPORATION'S RESPONSIBILITY FOR 
FINANCIAL REPORTING                                 Lockheed Martin Corporation


- --------------------------------------------------------------------------------
     The management of Lockheed Martin Corporation prepared and is responsible
for the consolidated financial statements and all related financial information
contained in this report. The consolidated financial statements, which include
amounts based on estimates and judgments, have been prepared in accordance with
generally accepted accounting principles applied on a consistent basis.

     The Corporation maintains a system of internal accounting controls designed
and intended to provide reasonable assurance that assets are safeguarded,
transactions are properly executed and recorded in accordance with management's
authorization, and accountability for assets is maintained. An environment that
establishes an appropriate level of control consciousness is maintained and
monitored and includes examinations by an internal audit staff and by the
independent auditors in connection with their annual audit.

     The Corporation's management recognizes its responsibility to foster a
strong ethical climate. Management has issued written policy statements which
document the Corporation's business code of ethics. The importance of ethical
behavior is regularly communicated to all employees through the distribution of
written codes of ethics and standards of business conduct, and through ongoing
education and review programs designed to create a strong compliance
environment.

     The Audit and Ethics Committee of the Board of Directors is composed of
eight outside directors. This Committee meets periodically with the independent
auditors, internal auditors and management to review their activities. Both the
independent auditors and the internal auditors have unrestricted access to meet
with members of the Audit and Ethics Committee, with or without management
representatives present.

     The consolidated financial statements have been audited by Ernst & Young
LLP, independent auditors, whose report follows.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS    Lockheed Martin Corporation



- --------------------------------------------------------------------------------
Board of Directors and Stockholders
Lockheed Martin Corporation


     We have audited the accompanying consolidated balance sheet of Lockheed
Martin Corporation as of December 31, 1998 and 1997, and the related
consolidated statements of earnings, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1998. These financial
statements are the responsibility of the Corporation's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Lockheed Martin Corporation at December 31, 1998 and 1997, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1998, in conformity with generally accepted accounting
principles.

     applicable to common stock for basic and diluted loss per share, the deemed
     preferred stock dividend was deducted from 1997 net earnings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 1998 


- --------------------------------------------------------------------------------
Note 1--Summary of Significant Accounting Policies

Organization--Lockheed Martin Corporation (Lockheed Martin 
or the Corporation) is engaged in the conception, research, design, development,
manufacture, integration and operation of advanced technology systems, products
and services. Its products and services range from aircraft, spacecraft and
launch vehicles to missiles, electronics, information systems,
telecommunications and energy management. The Corporation serves customers in
both domestic and international defense and commercial markets, with its
principal customers being agencies of the U.S. Government.

Basis of consolidation and use of estimates--The consolidated financial
statements include the accounts of wholly-owned and majority-owned subsidiaries.
Intercompany balances and transactions have been eliminated in consolidation.
The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions, including estimates of anticipated contract costs and revenues
utilized in the earnings recognition process, that affect the reported amounts
in the financial statements and accompanying notes. Actual results could differ
from those estimates. 

Common stock split--In October 1998, the Board of Directors of the Corporation
authorized a two-for-one split of the Corporation's common stock in the form of
a stock dividend. The stock split was effected on December 31, 1998 to
stockholders of record at the close of business on December 1, 1998. In the
accompanying Consolidated Statement of Earnings and Notes to Consolidated
Financial Statements, all references to shares of common stock and per share
amounts have been restated to reflect the stock split. In addition, an amount
equal to the par value of the shares distributed to effect the stock split has
been transferred from additional paid-in capital to common stock.

Classifications--Receivables and inventories are primarily attributable to
long-term contracts or programs in progress for which the related operating
cycles are longer than one year. In accordance with industry practice, these
items are included in current assets. Book overdrafts, which are immaterial, are
included in current liabilities. Certain amounts for prior years have been
reclassified to conform with the 1998 presentation. 

Cash and cash equivalents--Cash and cash equivalents are net of outstanding
checks that are funded daily as presented for payment. Cash equivalents are
generally comprised of highly liquid instruments with maturities of three months
or less when purchased. Due to the short maturity of these instruments, carrying
value on the Corporation's consolidated balance sheet approximates fair value.

Receivables--Receivables consist of amounts billed and currently due from
customers, and unbilled costs and accrued profits primarily related to revenues
on long-term contracts that have been recognized for accounting purposes but not
yet billed to customers. 

Inventories--Inventories are stated at the lower of cost or estimated net
realizable value. Costs on long-term contracts and programs in progress
represent recoverable costs incurred for production, allocable operating
overhead and, where appropriate, research and development and general and
administrative expenses. Pursuant to contract provisions, agencies of the U.S.
Government and certain other customers have title to, or a security interest in,
inventories related to such contracts as a result of progress payments and
advances. Such progress payments and advances are reflected as an offset against
the related inventory balances. Other customer advances are classified as
current liabilities. General and administrative expenses related to commercial
products and services provided essentially under commercial terms and conditions
are expensed as incurred. Costs of other product and supply inventories are
principally determined by the first-in, first-out or average cost methods.

Property, plant and equipment--Property, plant and equipment are carried
principally at cost. Depreciation is provided on plant and equipment generally
using accelerated methods during the first half of the estimated useful lives of
the assets; thereafter, straight-line depreciation generally is used. Estimated
useful lives generally range from 8 years to 40 years for buildings and 2 years
to 20 years for machinery and equipment. 

Intangible assets--Intangible assets related to contracts and programs acquired
are amortized over the estimated periods of benefit (15 years or less) and are
displayed on the consolidated balance sheet net of accumulated amortization of
$800 million and $651 million at December 31, 1998 and 1997, respectively. Cost
in excess of net assets acquired (goodwill) is amortized ratably over
appropriate periods, primarily 40 years, and is displayed on the consolidated
balance sheet net of accumulated amortization of $1,103 million and $881 million
at December 31, 1998 and 1997, respectively. The carrying values of intangible
assets, as well as other long-lived assets, are reviewed if, as described in
Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
changes in the facts and circumstances indicate potential impairment of their
carrying value, and any impairment determined is recorded in the current period.
Impairment is measured by comparing the discounted cash flows of the related
business operations to the appropriate carrying values. 

Investments--Other assets include investments in equity securities of affiliated
companies accounted for under the equity method of accounting. Under this method
of accounting, which generally applies to investments that represent a 20
percent to 50 percent ownership of the equity securities of the investees, the
Corporation's share of the earnings of the affiliated companies is included in
other income and expenses. The Corporation recognizes currently gains or losses
arising from issuances of stock by wholly-owned or majority-owned subsidiaries
or by equity method investees. These gains or losses are also included in other
income and expenses. Other assets also include investments in companies in which
the Corporation's ownership interest is less than 20 percent. These investments
are generally accounted for under the cost method of accounting. Total
investments included in other assets were $948 million and $645 million at
December 31, 1998 and 1997, respectively. 

Environmental matters--The Corporation records a liability for environmental
matters when it is probable that a liability has been incurred and the amount
can be reasonably estimated. A

                                                     Lockheed Martin Corporation



- --------------------------------------------------------------------------------
substantial portion of these costs are expected to be reflected in sales and
cost of sales pursuant to U.S. Government agreement or regulation. At the time a
liability is recorded for future environmental costs, an asset is recorded for
estimated future recovery considered probable through the pricing of products
and services to agencies of the U.S. Government. The portion of those costs
expected to be allocated to commercial business is reflected in cost of sales at
the time the liability is established.

Sales and earnings--Sales and anticipated profits under long-term fixed-price
production contracts are recorded on a percentage of completion basis, generally
using units of delivery as the measurement basis for effort accomplished.
Estimated contract profits are taken into earnings in proportion to recorded
sales. Sales under certain long-term fixed-price contracts which, among other
things, provide for the delivery of minimal quantities or require a significant
amount of development effort in relation to total contract value, are recorded
upon achievement of performance milestones or using the cost-to-cost method of
accounting where sales and profits are recorded based on the ratio of costs
incurred to estimated total costs at completion.

     Sales under cost-reimbursement-type contracts are recorded as costs are
incurred. Applicable estimated profits are included in earnings in the
proportion that incurred costs bear to total estimated costs. Sales of products
and services provided essentially under commercial terms and conditions are
recorded upon shipment or completion of specified tasks.

     Amounts representing contract change orders, claims or other items are
included in sales only when they can be reliably estimated and realization is
probable. Incentives or penalties and awards applicable to performance on
contracts are considered in estimating sales and profit rates, and are recorded
when there is sufficient information to assess anticipated contract performance.
Incentive provisions which increase or decrease earnings based solely on a
single significant event are generally not recognized until the event occurs.

     When adjustments in contract value or estimated costs are determined, any
changes from prior estimates are reflected in earnings in the current period.
Anticipated losses on contracts or programs in progress are charged to earnings
when identified.

Research and development and similar costs--Corporation-sponsored research and
development costs primarily include research and development and bid and
proposal efforts related to government products and services. Except for certain
arrangements described below, these costs are generally included as part of the
general and administrative costs that are allocated among all contracts and
programs in progress under U.S. Government contractual arrangements.
Corporation-sponsored product development costs not otherwise allocable are
charged to expense when incurred. Under certain arrangements in which a customer
shares in product development costs, the Corporation's portion of such
unreimbursed costs is expensed as incurred. Customer-sponsored research and
development costs incurred pursuant to contracts are accounted for as contract
costs.

Derivative financial instruments--The Corporation may use derivative financial
instruments to manage its exposure to fluctuations in interest rates and foreign
exchange rates. Forward exchange contracts are designated as qualifying hedges
of firm commitments or specific anticipated transactions. Gains and losses on
these contracts are recognized in income when the hedged transactions occur. At
December 31, 1998, the amounts of forward exchange contracts outstanding, as
well as the amounts of gains and losses recorded during the year, were not
material. The Corporation does not hold or issue derivative financial
instruments for trading purposes.

Stock-based compensation--The Corporation measures compensation cost for
stock-based compensation plans using the intrinsic value method of accounting as
prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees," and related interpretations. The Corporation has adopted
those provisions of SFAS No. 123, "Accounting for Stock-Based Compensation,"
which require disclosure of the pro forma effect on net earnings and earnings
per share as if compensation cost had been recognized based upon the estimated
fair value at the date of grant for options awarded.

New accounting pronouncements adopted--Effective January 1, 1998, the
Corporation adopted SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130
established new rules for reporting and disclosure of comprehensive income,
which is composed of net earnings and certain items of other comprehensive
income as defined in the Statement. The adoption of SFAS No. 130 had no impact
on the Corporation's net earnings. The Corporation's other comprehensive income
consists primarily of foreign currency translation adjustments. In prior years,
such adjustments were recorded in other liabilities; however, in 1998, the
accumulated balance related to foreign translation adjustments was reclassified
to stockholders' equity. The accumulated balance and activity for each year
presented were insignificant.
 
     Effective December 31, 1998, the Corporation adopted SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information." SFAS No.
131 established standards for the way in which publicly-held companies report
financial and descriptive information about their operating segments in
financial statements for both interim and annual periods, and requires
additional disclosures with respect to products and services, geographic areas
of operation and major customers. The adoption of SFAS No. 131 had no impact on
the number or composition of the Corporation's reported business segments, or on
its consolidated results of operations, cash flows or financial position, but
did increase the level of disclosure of segment information (see Note 17).

New accounting pronouncements to be adopted--In March 1998, the American
Institute of Certified Public Accountants (AICPA) issued Statement of Position
(SOP) No. 98-1, "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use." The SOP is effective for fiscal years beginning
after December 15, 1998, and will require the capitalization of certain costs
incurred in connection with developing or obtaining software for internal use
after the date of adoption. The Corporation will adopt this SOP effective
January 1, 1999. Although the adoption of this SOP is expected to affect the
timing of future cash flows under contracts with the U.S. Government, management
does not expect the adoption will have a material effect on the Corporation's
consolidated results of operations, cash flows or financial position.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
December 31, 1998


- --------------------------------------------------------------------------------
     In April 1998, the AICPA issued SOP No. 98-5, "Reporting on the Costs of
Start-Up Activities." SOP No. 98-5 provides authoritative guidance on accounting
and financial reporting related to costs of start-up activities. This SOP
requires that, at the effective date of adoption, costs of start-up activities
previously capitalized, primarily in inventories, be expensed and reported as a
cumulative effect of a change in accounting principle, and further requires that
such costs subsequent to adoption be expensed as incurred. SOP No. 98-5 is
effective for fiscal years beginning after December 15, 1998. The Corporation
will adopt this SOP effective January 1, 1999, and management estimates that the
amount of the cumulative effect adjustment to be recognized upon its adoption,
net of income tax benefits of approximately $230 million, will be approximately
$350 million.

     In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS
No. 133 provides authoritative guidance on accounting and financial reporting
for derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives), and for hedging
activities. The Statement requires the recognition of all derivatives as either
assets or liabilities in the consolidated balance sheet, and the periodic
measurement of those instruments at fair value. The classification of gains and
losses resulting from changes in the fair values of derivatives is dependent on
the intended use of the derivative and its resulting designation, as further
defined in the Statement. SFAS No. 133 requires adoption no later than January
1, 2000, but early adoption is allowed, and initial application must be as of
the beginning of a fiscal quarter. Additionally, the Statement cannot be applied
retroactively to prior periods. At adoption, existing hedging relationships must
be designated anew and documented pursuant to the provisions of the Statement.
The Corporation is currently analyzing and assessing the impact that the
adoption of SFAS No.133 is expected to have on its consolidated results of
operations, cash flows and financial position.

Note 2--Transaction Agreement with COMSAT Corporation

In September 1998, the Corporation and COMSAT Corporation (COMSAT) announced
that they had entered into an Agreement and Plan of Merger (the Merger
Agreement) to combine the companies in a two-phase transaction with a total
estimated value of approximately $2.7 billion at the date of the announcement
(the Merger). The Merger Agreement has been approved by the respective Boards of
Directors of the Corporation and COMSAT. In connection with the first phase of
this transaction, the Corporation commenced a cash tender offer (the Tender
Offer) on September 25, 1998, to purchase up to 49 percent, subject to certain
adjustments, of the outstanding shares of common stock of COMSAT on the date of
purchase at a price of $45.50 per share, with an estimated value of $1.2
billion. Under the Merger Agreement, the Tender Offer will be extended for
periods of up to 60 days until the earlier of (i) September 18, 1999, or (ii)
satisfaction of certain conditions to closing. The second phase of the
transaction, which will result in consummation of the Merger, will be
accomplished by an exchange of one share of Lockheed Martin common stock for
each share of COMSAT common stock.

     The consummation of the Tender Offer is subject to, among other things, the
approval of the Merger by the stockholders of COMSAT and certain regulatory
approvals, including approval by the Federal Communications Commission (FCC).
The stockholders of COMSAT are expected to vote on the proposed Merger at
COMSAT's annual meeting of stockholders on June 18, 1999. Upon closing, the
Corporation will account for its investment in COMSAT under the equity method of
accounting. Consummation of the Merger is subject to, among other things, the
enactment of legislation necessary to allow Lockheed Martin to acquire the
remaining shares of COMSAT common stock and certain additional regulatory
approvals including anti-trust clearance by the Department of Justice. The
Merger, upon consummation, will be accounted for under the purchase method of
accounting. If the Tender Offer is consummated but the necessary legislation is
not enacted and the additional regulatory approvals are not obtained, the
Corporation will not be able to achieve all of its objectives with respect to
the COMSAT transaction and will be unable to exercise control over COMSAT.

     The Corporation is not currently designated by the FCC as an "authorized
common carrier," and as such is prohibited from owning more than 10 percent of
COMSAT. The Corporation has filed an application with the FCC to be designated
an "authorized common carrier" and to purchase up to 49 percent of COMSAT. On
January 21, 1999, the Chairman of the House Committee on Commerce and the
Chairman of the Senate Subcommittee on Communications sent a letter to the FCC
urging the FCC not to take any action to permit any company to purchase more
than 10 percent of COMSAT prior to Congress adopting satellite industry reform
legislation. If the FCC were to delay or slow its review of the Corporation's
filings with respect to the Tender Offer, and if Congress does not make rapid
progress on satellite industry reform legislation, the Tender Offer may not be
consummated by September 18, 1999. If this occurs, either party may terminate
the Merger Agreement or both parties may elect to amend the Merger Agreement to
extend this date. If the FCC's review is not delayed or slowed and the Tender
Offer is consummated, but the legislative process relative to satellite industry
reform legislation moves slowly, the Merger is unlikely to occur in 1999.

     In August 1998, the Corporation announced the formation of Lockheed Martin
Global Telecommunications, Inc. (Global Telecommunications), a wholly-owned
subsidiary of the Corporation. Effective January 1, 1999, Global
Telecommunications combined investments in several existing joint ventures and
elements of the Corporation under a dedicated management team focused on
capturing a greater portion of the worldwide telecommunications services market.
The Corporation intends to combine the operations of Global Telecommunications
and COMSAT upon consummation of the Tender Offer and the Merger noted above.

Note 3--Transaction Agreement with General Electric Company

In November 1997, the Corporation exchanged all of the outstanding capital stock
of its wholly-owned subsidiary, LMT Sub, for all of the outstanding Series A
preferred stock held by General Electric Company (GE). The Series A preferred
stock was convertible into approximately 58 million shares of Lockheed Martin
common stock. LMT Sub was composed of two non-core commercial business units
which contributed approximately five percent of the

                                                     Lockheed Martin Corporation



- --------------------------------------------------------------------------------
Corporation's 1997 net sales, Lockheed Martin's investment in a
telecommunications partnership, and approximately $1.6 billion in cash, which
was initially financed through the issuance of commercial paper; however, $1.4
billion was subsequently refinanced with a note, due November 17, 2002 and
bearing interest at 6.04%, from Lockheed Martin to LMT Sub. The fair value of
the non-cash net assets exchanged was approximately $1.2 billion.

     The GE Transaction was accounted for at fair value, and resulted in the
reduction of the Corporation's stockholders' equity by $2.8 billion and the
recognition of a tax-free gain, in other income and expenses, of approximately
$311 million during the fourth quarter of 1997. For purposes of determining net
loss applicable to common stock used in the computation of loss per share, the
excess of the fair value of the consideration transferred to GE (approximately
$2.8 billion) over the carrying value of the Series A preferred stock ($1.0
billion) was treated as a deemed preferred stock dividend and deducted from 1997
net earnings in accordance with the requirements of the Emerging Issues Task
Force's Issue D-42. This deemed dividend had a significant impact on the loss
per share calculations, but did not impact reported 1997 net earnings. The
effect of this deemed dividend was to reduce the basic and diluted per share
amounts by $4.93.

     During the second quarter of 1998, the final determination of the closing
net worth of the businesses exchanged was completed, resulting in a payment of
$51 million from the Corporation to MRA Systems, Inc. (formerly LMT Sub). This
final settlement did not impact the gain previously recorded on the transaction.
Subsequently, the remainder of the cash included in the transaction was
refinanced with a note for $210 million, due November 17, 2002 and bearing
interest at 5.73%, from Lockheed Martin to MRA Systems, Inc.

Note 4--Other Acquisitions and Divestitures

In July 1997, the Corporation and Northrop Grumman Corporation (Northrop
Grumman) announced that they had entered into an agreement to combine the
companies whereby Northrop Grumman would become a wholly-owned subsidiary of
Lockheed Martin. The proposed merger with Northrop Grumman was terminated by the
Board of Directors of Lockheed Martin in July 1998.

     In March 1997, the Corporation executed a definitive agreement valued at
approximately $525 million to reposition 10 non-core business units as a new
independent company, L-3 Communications Corporation (L-3), in which the
Corporation retained an approximate 35 percent ownership interest at closing.
These business units contributed approximately two percent of the Corporation's
net sales during the three month period ended March 31, 1997. The transaction,
which closed on April 30, 1997 with an effective date of March 30, 1997, did not
have a material impact on the Corporation's earnings. During May 1998, L-3
completed an initial public offering resulting in the issuance of an additional
6.9 million shares of its common stock to the public. This transaction resulted
in a reduction in the Corporation's ownership to approximately 25 percent, and
the recognition of a pretax gain of $18 million in other income and expenses.
The gain increased net earnings by $12 million, or $.03 per diluted share. At
December 31, 1998 and 1997, the Corporation's investment in L-3 totaled $77
million and $49 million, respectively.

     In February 1999, 4.5 million shares previously owned by the Corporation
were sold as part of a secondary public offering by L-3. This transaction
resulted in a further reduction in the Corporation's ownership to approximately
7.1 percent. Management estimates that the gain recognized on this transaction
will increase net earnings for the first quarter of 1999 by an amount between
$75 million and $85 million. Subsequent to this transaction, the Corporation's
remaining investment in L-3 will be accounted for as an available-for-sale
investment, as defined in SFAS No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." Under SFAS No. 115, investments in
available-for-sale securities are adjusted to reflect current market values at
each reporting period, with resulting unrealized gains or losses, net of income
taxes, reported as a component of other comprehensive income. 

     During the third quarter of 1996, the Corporation announced its intention
to distribute via an exchange offer its 81 percent interest in Martin Marietta
Materials, Inc. (Materials) to its stockholders. In October 1996, approximately
15.8 million shares of the Corporation's common stock were exchanged for the
37.35 million shares of Materials common stock held by the Corporation. Upon the
closing of this transaction, the Corporation had no remaining ownership interest
in Materials and had reduced its common shares outstanding by approximately four
percent. This fourth quarter 1996 exchange was accounted for at fair value,
resulting in the reduction of the Corporation's stockholders' equity by $750
million and the recognition of a pretax gain of $365 million in other income and
expenses.

     In November 1996, the Corporation announced the proposed divestiture of two
of its business units, Armament Systems and Defense Systems. This transaction,
which concluded with the Corporation's receipt of $450 million in cash in
January 1997, had no pretax effect on the results of operations for 1997 or
1996.

     On a combined basis, the Materials exchange and the Armament Systems and
Defense Systems divestiture noted above increased 1996 net earnings by $351
million.

     In April 1996, the Corporation consummated its business combination with
Loral Corporation (Loral) for a total purchase price, including acquisition
costs, of approximately $7.6 billion (the Loral Transaction). In addition to the
acquisition of Loral's defense electronics and systems integration businesses,
the Loral Transaction resulted in the Corporation acquiring shares of preferred
stock of Loral Space & Communications, Ltd. (Loral SpaceCom), a newly-formed
company, which were convertible into 20 percent of Loral SpaceCom's common stock
on a diluted basis at the date of acquisition. The Corporation's investment in
Loral SpaceCom totaled $393 million at December 31, 1998 and 1997, and the fair
value at December 31, 1998 was estimated to be approximately $650 million. The
Loral Transaction was accounted for using the purchase method of accounting. The
businesses acquired in connection with the Loral Transaction have been included
in the results of operations of the Corporation since April 1996.

Note 5--Restructuring and Other Charges 

During the fourth quarter of 1998, CalComp Technology, Inc. (CalComp), a
majority-owned subsidiary of the Corporation, made a decision to divest certain
of its businesses and concluded

                                      36

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

- --------------------------------------------------------------------------------
an evaluation of its remaining operations. Later in the quarter, the Corporation
notified CalComp that it would not increase existing credit for CalComp to
support ongoing operations. Subsequently, the Corporation agreed to provide
financing, subject to certain conditions, for a plan providing for the timely
non-bankruptcy shutdown of CalComp's business. The above actions resulted in the
recording of a fourth quarter 1998 nonrecurring and unusual pretax charge, net
of state income tax benefits, of $233 million. This charge reduced net earnings
by $183 million, or $.48 per diluted share.

     The pretax charge reflected the effects of impairment related to goodwill
of approximately $75 million; writedowns of approximately $73 million to reflect
other assets at estimated recoverable values; estimated severance and other
costs related to employees of approximately $25 million; estimated costs related
to warranty obligations, and purchase and other commitments of approximately $37
million; and other estimated exit costs, primarily related to facilities, of
approximately $23 million.

     During the fourth quarter of 1997, the Corporation recorded nonrecurring
and unusual pretax charges, net of state income tax benefits, totaling $457
million, which reduced net earnings by $303 million. The charges were identified
in connection with the Corporation's review, which concluded in the fourth
quarter, of non-strategic lines of business, non-core investments and certain
other assets. Approximately $200 million of the pretax charges reflected the
estimated effects of exiting non-strategic lines of business, including amounts
related to the fixed price systems development line of business in the area of
children and family services, and related to increases in estimated exposures
relative to the environmental remediation lines of business initially identified
in 1996 and for which initial estimates of exposure were provided in the fourth
quarter of 1996. These increases in estimated exposures were based on more
current information, including deterioration in a partner's financial condition
as evidenced by the partner seeking protection under the bankruptcy laws. The
remaining charges reflected impairment in the values of various non-core
investments and certain other assets in keeping with the Corporation's continued
focus on core operations. These charges, in combination with the gain recognized
on the GE Transaction (see Note 3), decreased diluted loss per share for 1997 by
$.02.
  
     During the fourth quarter of 1996, the Corporation recorded nonrecurring
pretax charges, net of state income tax benefits, of $307 million, which
decreased net earnings by $209 million. Approximately one-half of the charges
reflected the estimated effects of terminating a business relationship formed to
provide environmental remediation services to government and commercial
customers worldwide, and the initial estimated effects related to management's
decision to exit a certain environmental remediation line of business. Charges
of approximately $85 million were identified in connection with an evaluation of
the Corporation's future strategic focus, and reflected impairment in the values
of non-core investments and certain other assets which were other than temporary
in nature. The remaining charges of approximately $75 million were related to
costs for facility closings and transfers of programs resulting from
management's decision to include the operations of the business units acquired
in the Loral Transaction in the Electronics, Information & Services, and Energy
and Other segments. These charges, combined with the effects of the Materials
exchange and the Armament Systems and Defense Systems divestiture (see Note 4),
increased diluted earnings per share by $.32.

     As of December 31, 1998, initiatives undertaken as part of the 1997 and
1996 charges relating to the Corporation's reviews of non-core investments and
certain other assets which resulted in impairment in values of those assets,
facility closings and transfers of programs resulting from the consummation of
the Loral Transaction, and the termination of a business relationship formed to
provide environmental remediation services, which in total represented
approximately 75 percent of the amounts originally recorded, have been completed
consistent with the Corporation's original plans and estimates. Actions
contemplated as part of the Corporation's exit from a certain environmental
remediation line of business and a fixed price systems development line of
business in the area of children and family services have not been completed.
Accordingly, included in liabilities at December 31, 1998 are amounts related to
these actions which, in the opinion of management, are adequate to complete the
remaining initiatives originally contemplated in the 1997 and 1996 charges.
During 1998 and 1997, the effects on the Corporation's net earnings of
adjustments associated with these charges were not material.

     During 1995, the Corporation recorded pretax charges of $690 million from
merger related expenses in connection with the formation of Lockheed Martin and
the related corporate-wide consolidation plan. The charges represented the
portion of the accrued costs and net realizable value adjustments that were not
probable of recovery. In addition, the Corporation has incurred costs through
the end of 1998 which were anticipated in the 1995 consolidation plan but had
not met the requirements for accrual earlier. These costs include relocation of
personnel and programs, retraining, process re-engineering and certain capital
expenditures, among others. As of December 31, 1998, cumulative merger related
and consolidation payments were approximately $1.1 billion. Consistent with the
original 1995 consolidation plan, consolidation actions were substantially
completed by December 31, 1998, with only approximately $120 million of such
costs remaining to be incurred over the next two years.

     Under existing U.S. Government regulations, certain costs incurred for
consolidation actions that can be demonstrated to result in savings in excess of
the cost to implement can be deferred and amortized for government contracting
purposes and included as allowable costs in future pricing of the Corporation's
products and services. Included in other assets at December 31, 1998 is
approximately $450 million of deferred costs that will be recognized in future
sales and cost of sales.

Note 6--Earnings Per Share 

As previously disclosed, all share and per share amounts for prior years have
been restated to reflect the Corporation's December 1998 two-for-one stock split
in the form of a stock dividend. Basic earnings per share were computed based on
net earnings, less the dividend requirement for preferred stock to the date of
redemption, and less the deemed preferred stock dividend resulting from the
November 1997 GE Transaction representing the excess of the fair value of the
consideration transferred to GE (approximately $2.8 billion) over the carrying
value of the Lockheed Martin preferred

stock redeemed ($1.0 billion). The weighted average number of common shares
outstanding during the year was used in this calculation. Diluted earnings per
share for 1998 and 1996 were computed based on net earnings. For these
calculations, the weighted average number of common shares outstanding was
increased by the dilutive effect of stock options based on the treasury stock
method and, for 1996, by the assumed conversion of preferred stock. Diluted loss
per share for 1997 was computed in the same manner as basic loss per share, as
the adjustments related to the assumed conversion of the preferred stock (50.6
million common shares) and the related dividend requirement for the preferred
stock ($53 million) to the date of redemption, and the dilutive effect of stock
options (5.8 million common shares), were not made since they would have had
antidilutive effects.

     The following table sets forth the computations of basic and diluted
earnings per share:

</TABLE> 

     In the second quarter of 1998 and the fourth quarter of 1997, in connection
with the GE Transaction, the Corporation issued notes for $210 million, bearing
interest at 5.73%, and $1.4 billion, bearing interest at 6.04%, respectively, to
a wholly-owned subsidiary of GE. The notes are due November 17, 2002. In
December 1998, the Corporation repaid $200 million against the notes. The
agreements relating to these notes require that, so long as the aggregate
principal amount of the notes exceed $1 billion, the Corporation will recommend
to its stockholders the election of one person designated by GE to serve as a
director of the Corporation.

     The registered holders of $300 million of 40 year Debentures issued in 1996
may elect, between March 1 and April 1, 2008, to have each of their Debentures
repaid by the Corporation on May 1, 2008.

     Included in Debentures are $110 million of 7% obligations ($175 million at
face value) which were originally sold at approximately 54 percent of their
principal amount. These Debentures, which are redeemable in whole or in part at
the Corporation's option at 100 percent of their face value, have an effective
yield of 13.25%.

     A leveraged employee stock ownership plan (ESOP) incorporated into the
Corporation's salaried savings plan borrowed $500 million through a private
placement of notes in 1989. These notes are being repaid in quarterly
installments over terms ending in 2004. The ESOP note agreement stipulates that,
in the event that the ratings assigned to the Corporation's long-term senior
unsecured debt are below investment grade, holders of the notes may require the
Corporation to purchase the notes and pay accrued interest. These notes are
obligations of the ESOP but are guaranteed by the Corporation and included as
debt in the Corporation's consolidated balance sheet.

     At the end of 1998, the Corporation had a long-term revolving credit
facility, which matures on December 20, 2001, in the amount of $3.5 billion, and
a short-term revolving credit facility, which matures on May 28, 1999, in the
amount of $2.5 billion (collectively, the Credit Facilities). Borrowings under
the Credit Facilities would be unsecured and bear interest, at the Corporation's
option, at rates based on the Eurodollar rate or a bank Base Rate (as defined).
Each bank's obligation to make loans under the Credit Facilities is subject to,
among other things, compliance by the Corporation with various representations,
warranties, covenants and agreements, including, but not limited to, covenants
limiting the ability of the Corporation and certain of its subsidiaries to
encumber their assets and a covenant not to exceed a maximum leverage ratio.

     No borrowings were outstanding under the Credit Facilities at December 31,
1998. However, the Credit Facilities support commercial paper borrowings of
approximately $1.3 billion outstanding at December 31, 1998, of which $300
million has been classified as long-term debt in the Corporation's consolidated
balance sheet based on management's ability and intention to maintain this
amount of debt outstanding for at least one year.

     Excluding commercial paper classified as long-term, the Corporation's
long-term debt maturities for the five years following December 31, 1998 are:
$886 million in 1999; $64 million in 2000; $803 million in 2001; $1,506 million
in 2002; $858 million in 2003; and $5,426 million thereafter. 

     Certain of the Corporation's other financing agreements contain restrictive
covenants relating to debt, limitations on encumbrances and sale and lease-back
transactions, and provisions which relate to certain changes in control.

     SFAS No. 107, "Disclosures about Fair Value of Financial Instruments," and
SFAS No. 119, "Disclosure about Derivative Financial Instruments and Fair Value
of Financial Instruments," require the disclosure of the fair value of financial
instruments, including assets and liabilities recognized and not recognized in
the consolidated balance sheet, for which it is practicable to estimate fair
value. Unless otherwise indicated elsewhere in the notes to the consolidated
financial statements, the carrying value of the Corporation's financial
instruments approximates fair value. The estimated fair values of the
Corporation's long-term debt instruments at December 31, 1998, aggregated
approximately $10.5 billion, compared with a carrying amount of approximately
$9.8 billion. The fair values were estimated based on quoted market prices for
those instruments publicly traded. For privately placed debt, the fair values
were estimated based on the quoted market prices for similar issues, or on
current rates offered to the Corporation for debt with similar remaining
maturities.

     Interest payments were $856 million in 1998, $815 million in 1997 and $655
million in 1996.

Note 13--Stockholders' Equity and Related Items

Capital structure--At December 31, 1998, the authorized capital of the
Corporation was composed of 1.5 billion shares of common stock (approximately
393 million shares issued), 50 million shares of series preferred stock (no
shares issued), and 20 million shares of Series A preferred stock (no shares
outstanding).

     In 1995, the Corporation's Board of Directors authorized a common stock
repurchase plan for the repurchase of up to 18 million common shares to counter
the dilutive effect of common stock issued under certain of the Corporation's
benefit and compensation programs and for other purposes related to such plans.
No shares were repurchased in 1998, 1997 or 1996 under this plan.

Stock option and award plans--In March 1995, the stockholders approved the
Lockheed Martin 1995 Omnibus Performance Award Plan (the Omnibus Plan). Under
the Omnibus Plan, employees of the Corporation may be granted stock-based
incentive awards, including options to purchase common stock, stock appreciation
rights, restricted stock or other stock-based incentive awards. Employees may
also be granted cash-based incentive awards, such as performance units. These
awards may be granted either individually or in combination with other awards.
The Omnibus Plan requires that options to purchase common stock have an exercise
price of not less than 100 percent of the market value of the underlying stock
on the date of grant. The number of shares of Lockheed Martin common stock
reserved for issuance under the Omnibus Plan at December 31, 1998 was 39 million
shares. The Omnibus Plan does not impose any minimum vesting periods on options
or other awards. The maximum term of an option or any other award is 10 years.
The Omnibus Plan allows the Corporation to provide for financing of purchases of
its common stock, subject to certain conditions, by interest-bearing notes
payable to the Corporation.

     The following table summarizes the stock option activity of the
Corporation's plans during 1996, 1997 and 1998:

==================================================================================================================
</TABLE> 

     All stock-based incentive awards granted in 1998, 1997 and 1996 under the
Omnibus Plan were stock options which have 10 year terms, and virtually all of
which vest over a two year service period. Exercise prices of options awarded in
those years were equal to the market price of the stock on the date of grant.
Pro forma information regarding net earnings and earnings per share as required
by SFAS No. 123 has been prepared as if the Corporation had accounted for its
employee stock options under the fair value method. The fair value for these
options was estimated at the date of grant using the Black-Scholes option
pricing model with the following weighted-average assumptions for 1998, 1997 and
1996, respectively: risk-free interest rates of 5.39 percent, 6.36 percent and
5.58 percent; dividend yields of 1.9 percent, 1.5 percent and 1.7 percent;
volatility factors related to the expected market price of the Corporation's
common stock of .174, .163 and .186; and a weighted average expected option life
of five years. The weighted average fair values of options granted during 1998,
1997 and 1996 were $10.96, $10.94 and $8.62, respectively.

     For purposes of pro forma disclosures, the options' estimated fair values
are amortized to expense over the options' vesting periods.

Note 14--Post-Retirement Benefit Plans

Effective January 1, 1998, the Corporation adopted SFAS No. 132, "Employers'
Disclosures about Pension and Other Post-retirement Benefits." SFAS No. 132
revised disclosure requirements for pension and other post-retirement benefit
plans; however, it did not change the measurement or recognition provisions of
existing accounting literature. In accordance with SFAS No. 132, prior year
disclosures relating to pension and post-retirement benefit plans have been
restated for comparative purposes.

Defined Contribution Plans--The Corporation maintains a number of defined
contribution plans which cover substantially all employees, the most significant
of which are the 401(k) plans for salaried employees and hourly employees. Under
the provisions of these 401(k) plans, employees' eligible contributions are
matched by the Corporation at established rates. The Corporation's matching
obligations were $226 million in 1998, $212 million in 1997 and $202 million in
1996.

     The Lockheed Martin Corporation Salaried Savings Plan includes an ESOP
which purchased 34.8 million shares of the Corporation's common stock with the
proceeds from a $500 million note issue which is guaranteed by the Corporation.
The Corporation's match consisted of shares of its common stock, which was
partially fulfilled with stock released from the ESOP at approximately 2.4
million shares per year based upon the debt repayment schedule through the year
2004, with the remainder being fulfilled through purchases of common stock from
terminating participants or in the open market, or through newly issued shares
from the Corporation. Interest incurred on the ESOP debt totaled $23 million,
$26 million and $29 million in 1998, 1997 and 1996, respectively. Dividends
received by the ESOP with respect to unallocated shares held are used for debt
service. The ESOP held approximately 39.8 million issued shares of the
Corporation's common stock at December 31, 1998, of which approximately 27.1
million were allocated and 12.7 million were unallocated. Unallocated common
shares held by the ESOP are considered outstanding for voting and other
Corporate purposes, but excluded from weighted average outstanding shares in
calculating earnings per share. For 1998, 1997 and 1996, the weighted average
unallocated ESOP shares excluded in calculating earnings per share totaled
approximately 13.6 million, 15.8 million and 18.2 million common shares,
respectively. The fair value of the unallocated ESOP shares at December 31, 1998
was approximately $540 million.

     Certain plans for hourly employees include non-leveraged ESOPs. The
Corporation's match to these plans was made through cash contributions to the
ESOP trusts which were used, in part, to purchase common stock from terminating
participants and in the open market for allocation to participant accounts.
These ESOP trusts held approximately 3.6 million issued and outstanding shares
of common stock at December 31, 1998.

- --------------------------------------------------------------------------------
     Dividends paid to the salaried and hourly ESOP trusts on the allocated
shares are paid annually by the ESOP trusts to the participants based upon the
number of shares allocated to each participant.

Defined Benefit Pension Plans, and Retiree Medical and Life Insurance
Plans--Most employees are covered by defined benefit pension plans, and certain
health care and life insurance benefits are provided to eligible retirees by the
Corporation. The Corporation has made contributions to trusts (including
Voluntary Employees' Beneficiary Association trusts and 401(h) accounts, the
assets of which will be used to pay expenses of certain retiree medical plans)
established to pay future benefits to eligible retirees and dependents. Benefit
obligations as of the end of each year reflect assumptions in effect as of those
dates. Net pension and net retiree medical costs for 1998 and 1996 were based on
assumptions in effect at the end of the respective preceding years. Effective
October 1997, the Corporation changed its expected long-term rate of return on
assets related to its defined benefit pension and retiree medical plans.

     The following provides a reconciliation of benefit obligations, plan assets
and funded status of the plans:

</TABLE> 

     The following actuarial assumptions were used to determine the benefit
obligations and the net costs related to the Corporation's defined benefit
pension and post-retirement benefit plans, as appropriate:

<TABLE>

==============================================================================
</TABLE> 

     The medical trend rates used in measuring the post-retirement benefit
obligation were 6.7 percent in 1998 and 7.0 percent in 1997, and were assumed to
gradually decrease to 4.5 percent by the year 2004. An increase and decrease of
one percentage point in the assumed medical trend rates would result in a change
in the benefit obligation of approximately 5.9 percent and (5.2) percent,
respectively, at December 31, 1998, and a change in the 1998 post-retirement
benefit cost of approximately 8.9 percent and (7.8) percent, respectively. The
medical trend rate for 1999 is 6.0 percent.

     The change in the discount rate and in the rate of increase in future
compensation levels increased the benefit obligation for defined benefit pension
plans at December 31, 1998 by approximately $770 million. The change in discount
rate increased the benefit obligation for retiree medical plans at December 31,
1998 by approximately $110 million. 

Note 15--Leases 

Total rental expense under operating leases, net of immaterial amounts of
sublease rentals and contingent rentals, were $285 million, $295 million and
$320 million for 1998, 1997 and 1996, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
December 31, 1998


- --------------------------------------------------------------------------------
     Future minimum lease commitments at December 31, 1998 for all operating
leases that have a remaining term of more than one year were approximately
$1,148 million ($264 million in 1999, $203 million in 2000, $174 million in
2001, $142 million in 2002, $121 million in 2003, and $244 million in later
years). Certain major plant facilities and equipment are furnished by the U.S.
Government under short-term or cancelable arrangements.

Note 16--Commitments and Contingencies

The Corporation or its subsidiaries are parties to or have property subject to
litigation and other proceedings, including matters arising under provisions
relating to the protection of the environment. In the opinion of management and
in-house counsel, the probability is remote that the outcome of these matters
will have a material adverse effect on the Corporation's consolidated results of
operations or financial position. These matters include the following items:

Environmental matters--The Corporation entered into a consent decree with the
U.S. Environmental Protection Agency (EPA) in 1991 relating to certain property
in Burbank, California, which obligated the Corporation to design and construct
facilities to monitor, extract and treat groundwater, and to operate and
maintain such facilities for approximately eight years. The Corporation entered
into a follow-on consent decree in 1998 which obligates the Corporation to fund
the continued operation and maintenance of these facilities through the year
2018. The Corporation has also been operating under a cleanup and abatement
order from the California Regional Water Quality Control Board (the Regional
Board) affecting its facilities in Burbank, California. This order requires site
assessment and action to abate groundwater contamination by a combination of
groundwater and soil cleanup and treatment. The Corporation estimates that total
expenditures required over the remaining terms of the consent decrees and the
Regional Board order will be approximately $110 million.
 
     The Corporation is responding to three administrative orders issued by the
Regional Board in connection with the Corporation's former Lockheed Propulsion
Company facilities in Redlands, California. Under the orders, the Corporation is
investigating the impact and potential remediation of regional groundwater
contamination by perchlorates and chlorinated solvents. The Regional Board has
approved the Corporation's plan to maintain public water supplies with respect
to chlorinated solvents during this work, and the Corporation is negotiating
with local water purveyors to implement this plan, as well as to address water
supply concerns relative to perchlorate contamination. The Corporation estimates
that expenditures required to implement work currently approved will be
approximately $110 million. The Corporation is also coordinating with the U.S.
Air Force, which is conducting preliminary studies of the potential health
effects of exposure to perchlorates in connection with several sites across the
country, including the Redlands site. The results of these studies indicate that
current efforts with water purveyors regarding perchlorate issues are
appropriate; however, the Corporation currently cannot project the extent of its
ultimate clean-up obligation with respect to perchlorates, if any.

     The Corporation is involved in other proceedings and potential proceedings
relating to environmental matters, including disposal of hazardous wastes and
soil and water contamination. The extent of the Corporation's financial exposure
cannot in all cases be reasonably estimated at this time. In addition to the
amounts with respect to the Burbank and Redlands properties described above, a
liability of approximately $240 million for the other cases in which an estimate
of financial exposure can be determined has been recorded.

     Under an agreement with the U.S. Government, the Burbank groundwater
treatment and soil remediation expenditures referenced above are being allocated
to the Corporation's operations as general and administrative costs and, under
existing government regulations, these and other environmental expenditures
related to U.S. Government business, after deducting any recoveries from
insurance or other potentially responsible parties, are allowable in
establishing the prices of the Corporation's products and services. As a result,
a substantial portion of the expenditures are being reflected in the
Corporation's sales and cost of sales pursuant to U.S. Government agreement or
regulation. Although the Defense Contract Audit Agency has questioned certain
elements of the Corporation's practices with respect to the aforementioned
agreement, no formal action has been initiated, and it is management's opinion
that the treatment of these environmental costs is appropriate and consistent
with the terms of such agreement. The Corporation has recorded an asset for the
portion of environmental costs that are probable of future recovery in pricing
of the Corporation's products and services for U.S. Government business. The
portion that is expected to be allocated to commercial business has been
reflected in cost of sales. The recorded amounts do not reflect the possible
future recovery of portions of the environmental costs through insurance policy
coverage or from other potentially responsible parties, which the Corporation is
pursuing as required by agreement and U.S. Government regulation. Any such
recoveries, when received, would reduce the Corporation's liability as well as
the allocated amounts to be included in the Corporation's U.S. Government sales
and cost of sales.

Waste remediation contract--In 1994, the Corporation was awarded a $180 million
fixed price contract by the U.S. Department of Energy (DOE) for the Phase II
design, construction and limited test of remediation facilities, and the Phase
III full remediation of waste found in Pit 9, located on the Idaho National
Engineering and Environmental Laboratory reservation. The Corporation incurred
significant unanticipated costs and scheduling issues due to complex technical
and contractual matters which threatened the viability of the overall Pit 9
program. Based on an investigation by management to identify and quantify the
overall effect of these matters, the Corporation submitted a request for
equitable adjustment (REA) to the DOE on March 31, 1997 that sought, among other
things, the recovery of a portion of unanticipated costs incurred by the
Corporation and the restructuring of the contract to provide for a more
equitable sharing of the risks associated with the Pit 9 project. The
Corporation has been unsuccessful in reaching any agreements with the DOE on
cost recovery or other contract restructuring matters. Starting in May 1997, the
Corporation reduced work activities at the Pit 9 site while awaiting technical
direction from the DOE.

- --------------------------------------------------------------------------------
     On June 1, 1998, the DOE, through Lockheed Martin Idaho Technologies
Company (LMITCO), its management contractor, terminated the Pit 9 contract for
default. On that same date, the Corporation filed a lawsuit against the DOE in
the U.S. Court of Federal Claims in Washington, D.C., challenging and seeking to
overturn the default termination. In addition, on July 21, 1998, the Corporation
withdrew the REA previously submitted to the DOE and replaced it with a
certified REA. The certified REA is similar in substance to the REA previously
submitted, but its certification, based upon more detailed factual and
contractual analysis, raises its status to that of a formal claim. On August 11,
1998, LMITCO, at the DOE's direction, filed suit against the Corporation in U.S.
District Court in Boise, Idaho, seeking, among other things, recovery of
approximately $54 million previously paid by LMITCO to the Corporation under the
Pit 9 contract. The Corporation intends to resist this action while continuing
to pursue its certified REA. On January 26, 1999, the U.S. District Court in
Idaho granted the Corporation's motion and stayed the Idaho proceeding until
resolution of the motion to dismiss the lawsuit in the U.S. Court of Federal
Claims, or until August 2, 1999. The Corporation continues to assert its
position in the litigation while continuing its efforts to resolve the dispute
through non-litigation means.

Letters of credit and other matters--The Corporation has entered into standby
letter of credit agreements and other arrangements with financial institutions
primarily relating to the guarantee of future performance on certain contracts.
At December 31, 1998, the Corporation had contingent liabilities on outstanding
letters of credit, guarantees, and other arrangements aggregating approximately
$1.3 billion.

Note 17--Information on Industry Segments and Major Customers

The Corporation operates in four principal business segments: Space & Strategic
Missiles, Electronics, Aeronautics and Information & Services. All other
activities of the Corporation fall within the Energy and Other segment. These
segments, which constitute groupings of business units that offer different
products and services, are managed separately. Transactions between segments are
generally negotiated and accounted for under terms and conditions that are
similar to other government and commercial contracts; however, these
intercompany transactions are eliminated in consolidation. Other accounting
policies of the business segments are the same as those described in Note
1--Summary of Significant Accounting Policies.

Space & Strategic Missiles--Engaged in the design, development, engineering and
production of civil, commercial and military space systems, including
spacecraft, space launch vehicles, manned space systems and their supporting
ground systems and services; telecommunications systems and services; strategic
fleet ballistic missiles; and defensive missiles. In addition to its
consolidated business units, the segment has significant investments in joint
ventures and other unconsolidated companies. These companies are principally
engaged in businesses which complement and enhance other activities of the
segment.

Electronics--Engaged in the design, development, integration and production of
high performance electronic systems for undersea, shipboard, land, airborne and
space-based applications. Major defense product lines include surface ship and
submarine combat systems; anti-submarine warfare systems; air defense systems;
tactical battlefield missiles; aircraft controls; electronic-warfare systems;
electro-optic and night-vision systems; radar and fire control systems;
displays; and systems integration of mission specific combat suites. Major
commercial product lines include postal automation systems, aircraft engine
controls and satellite electronics.

Aeronautics--Engaged in the following primary lines of business: tactical
aircraft, air mobility, surveillance/command, maintenance/
modification/logistics, reconnaissance, platform systems integration and
advanced development programs. Major programs include the F-22 air-superiority
fighter, Joint Strike Fighter, F-16 multi-role fighter, C-130J tactical
transport, X-33 reusable launch vehicle technology demonstrator, Airborne Early
Warning & Control systems and various maintenance/modification/logistics
programs. 

Information & Services--Engaged in the development, integration and operation of
large, complex information systems; engineering, technical, and management
services for federal customers; transaction processing systems and services for
state and local government agencies; commercial information technology services;
real-time 3-D graphics technology and enterprise data management software; and
the provision of internal information technology support to the Corporation.

Energy and Other--The Corporation manages certain facilities for the DOE. The
contractual arrangements provide for the Corporation to be reimbursed for the
cost of operations and receive a fee for performing management services. The
Corporation reflects only the management fee in its sales and earnings for these
government-owned facilities. In addition, while the employees at such facilities
are employees of the Corporation, applicable employee benefit plans are separate
from the Corporation's plans. The Corporation also provides environmental
remediation services to commercial and U.S. Government customers. In addition,
this segment includes the Corporation's investments in joint ventures and
certain other businesses, including its investments in Loral SpaceCom and L-3
disclosed previously. Through October 1996, the Corporation provided
construction aggregates and specialty chemical products to commercial and civil
customers through its Materials subsidiary. 

Effective January 1, 1999, the Corporation combined its investments in several
existing joint ventures and certain elements of the Corporation to form Global
Telecommunications, which will be included in the Energy and Other segment. Such
investments were transferred from the Space & Strategic Missiles and Information
& Services segments. The formation of Global Telecommunications did not have a
material impact on the assets of these segments, nor is it expected to
materially impact their future results of operations.

===============================================================================
</TABLE> 

(a)  Earnings for the third quarter of 1998 include an adjustment resulting from
     significant improvement in the Atlas launch vehicle program based upon a
     current evaluation of the program's historical performance. This change in
     estimate increased pretax earnings by $120 million, net of state income
     taxes, and increased net earnings by $78 million, or $.21 per diluted
     share.

(b)  Earnings for the fourth quarter of 1998 include the effects of a
     nonrecurring and unusual after-tax charge of $183 million, or $.48 per
     diluted share, related to CalComp, a majority-owned subsidiary of the
     Corporation (see Note 5). In addition, fourth quarter results include the
     impact of the restructure of a commercial satellite program which increased
     net earnings by approximately $32 million, or $.08 per diluted share.

(c)  Earnings for the fourth quarter of 1997 include the effects of certain
     nonrecurring and unusual items, including a tax-free gain of $311 million
     and after-tax charges of $303 million, which resulted in a $.02 increase
     per diluted share (see Notes 3 and 5). The Corporation also changed its
     expected long-term rate of return on benefit pension plan assets effective
     October 1997, which decreased pension cost by approximately $70 million.

(d)  The diluted loss per share for the fourth quarter of 1997 includes the
     effects of a deemed preferred stock dividend resulting from the GE
     Transaction. The excess of the fair value of the consideration transferred
     to GE (approximately $2.8 billion) over the carrying value of the Series A
     preferred stock ($1.0 billion) was treated as a deemed preferred stock
     dividend and deducted from 1997 net earnings in determining net loss
     applicable to common stock used in the computation of loss per share. The
     effect of this deemed dividend was to reduce the diluted per share amount
     by $4.90.

Notes to Nine Year Summary

(a)  The Corporation was formed in 1995 from the combination of Lockheed
     Corporation and Martin Marietta Corporation. All financial information
     prior to 1995 was derived from the financial statements of those companies
     under the pooling of interests method of accounting.

(b)  All share and per share amounts have been restated to reflect the
     two-for-one stock split in the form of a stock dividend in December 1998.

(c)  Includes the effects of a nonrecurring and unusual pretax charge of $233
     million, $183 million after tax, or $.48 per diluted share.

(d)  Includes the effects of a tax-free gain of $311 million and the effects of
     nonrecurring and unusual pretax charges of $457 million, $303 million after
     tax which, on a combined basis, decreased diluted loss per share by $.02.
     Loss per share also includes the effects of the deemed preferred stock
     dividend resulting from the GE Transaction which reduced the basic and
     diluted per share amounts by $4.93.
