Item 1.  Business

                                     GENERAL

         Raytheon Company ("Raytheon" or the "Company") is a global technology
leader, with worldwide 1998 sales of more than $19.5 billion. The Company
provides products and services in the areas of defense and commercial
electronics, engineering and construction, and business and special mission
aircraft. Raytheon has operations throughout the United States and serves
customers in more than 80 countries around the world.

         The Company, formerly known as HE Holdings, Inc. ("HE Holdings"), is
the surviving company of the December 17, 1997 merger (the "Hughes Merger") of
HE Holdings, Inc. and Raytheon Company, a Delaware corporation ("Former
Raytheon"). At the effective time of the Hughes Merger, the separate legal
existence of Former Raytheon ceased and HE Holdings was renamed "Raytheon
Company." Although, from a legal point of view, HE Holdings, Inc. is the
surviving company of the Hughes Merger, the Company's business is largely
conducted in the same manner as and under the senior management of Former
Raytheon. Accordingly, the historical disclosures in this Form 10-K for years
prior to 1998 and any year-to-year comparisons contained herein for years prior
to 1998, unless otherwise specifically noted, relate to the operations of Former
Raytheon, as a predecessor to the Company by merger, and not to HE Holdings,
Inc. as it existed prior to the Hughes Merger.

                                BUSINESS SEGMENTS

Electronics

        Defense Electronics. Simultaneously with the consummation of the Hughes
Merger on December 17, 1997, Raytheon announced the creation of Raytheon Systems
Company ("RSC") to integrate Raytheon's defense electronics businesses. RSC
represents the combination and consolidation of the legacy defense
organizations--the former defense operations of Hughes Electronics Corporation
("Hughes Defense") and the defense assets of Texas Instruments, Inc. ("TI
Defense"), Raytheon E-Systems and Raytheon Electronics Systems. Raytheon's
defense electronics businesses are engaged in the design, manufacture and
service of advanced electronic devices, equipment and systems for both
government and commercial customers. In addition to defense electronics systems,
Raytheon has been successful in the conversion of certain defense electronics
technologies to commercial and non-defense applications such as air traffic
control, environmental monitoring and communications.

         For public reporting purposes, certain operating segments within
Electronics have been aggregated as they exhibit similar long-term financial
performance characteristics and do not meet the quantitative threshold. All
material intercompany transactions have been eliminated. During 1998 the
reportable segments within Electronics included the following: Defense Systems;
Sensors and Electronics Systems; Intelligence, Information, and Aircraft
Integration Systems; and a combined group made up of Command, Control, and
Communications Systems, Training and Services, and Commercial Electronics and
Other.


                                       4

         During the first quarter of 1999, the Company completed a
reorganization of certain business segments to better align the operations with
customer needs and to eliminate management redundancy. The Intelligence,
Information, and Aircraft Integration Systems segment, with the exception of its
Aircraft Integration Systems division was merged with Command, Control, and
Communications Systems to create Command, Control, Communication, and
Information Systems. The Aircraft systems division was established as a separate
segment called Aircraft Integration Systems. The impact of this organizational
change is reflected in the descriptions below, and will be incorporated into the
Company's 1999 financial statements.

         Defense Systems. The Defense Systems segment ("DSS") focuses on
anti-ballistic missile systems; air defense; air-to-air, surface-to-air, and
air-to-surface missiles; naval and maritime systems; ship self-defense systems;
torpedoes; strike, interdiction and cruise missiles; and advanced munitions.

         DSS produces the Patriot ground-based air defense missile system, which
is capable of tracking and intercepting enemy aircraft, cruise missiles, and
tactical ballistic missiles. In addition to the U.S., eight nations have
selected Patriot as an integral part of their air defense systems. Since the end
of the Gulf War in 1991, Raytheon has received over $3 billion in international
orders for Patriot equipment and services. In addition, DSS leads Raytheon's
efforts as the prime contractor for the Hawk ground-launched missile, which is
in service with 18 allied nations in addition to the U.S.

         DSS develops ground-based phased-array radars, including the X-Band
Radar (XBR) and Upgrade Early Warning Radar (UEWR) for National Missile Defense,
as well as the Ground-Based Radar (GBR) for the Theater High Altitude Area
Defense (THAAD) system, part of the U.S. Army's Theater Missile Defense Program.
It also is developing next generation theater missile interceptors for the Navy
Area Defense (NAD) and Navy Theater Wide (NTW) systems and the Exoatmospheric
Kill Vehicle (EKV) for National Missile Defense.

         DSS manufactures the primary air-to-air missile for the U.S. Air Force
and Navy fighter aircraft - the Advanced Medium Range Air-to-Air Missile
(AMRAAM), and is developing the AIM-9X (short-range missile). Other missiles
produced by DSS include Tomahawk, TOW, Stinger, Maverick, and Standard.

         DSS also leads Raytheon's efforts as the prime contractor for the NATO
Sea-Sparrow Surface to Air Missile System (NSSMS), DSS also produces the air-
and surface-launched versions of the Sparrow missile for both the U.S. and
foreign Navies. DSS also produces Phalanx and the Rolling Airframe Missile
(RAM), which the U.S. and foreign Navies use as part of the ship self-defense
system. DSS also develops sonars, combat control systems, minehunting equipment
and torpedoes for submarines and ships in U.S. and allied fleets, in addition to
designing unmanned underwater vehicles and laser sensors. DSS produces a variety
of shipboard radar systems. DSS also leads Raytheon's development efforts on the
U.S. Navy's next generation of surface combatant ships, the DD-21.


                                       5

         DSS strike weapons programs include the High Speed Anti-Radiation
Missile (HARM), Paveway laser-guided bombs, Extended Range Guided Munitions
(ERGM), XM-982, Joint Stand Off Weapon (JSOW), and Javelin. Also, Raytheon
through DSS is the prime contractor for the U.S. Army's Enhanced Fiber Optic
Guided Missile (EFOGM) demonstration program, which is intended to provide
rapidly deployable, lethal and highly survivable technologies to the U.S. early
entry forces.

         Sensors and Electronic Systems. The Sensors and Electronic Systems
segment ("SES") specializes in radar, electronic warfare, infrared, laser, and
GPS technologies. Its programs focus on land, naval, airborne and spaceborne
systems used for surveillance, reconaissance, targeting, navigation, commercial
and scientific applications.

         SES airborne radars are deployed on four operational tactical fighter
aircraft operated by U.S. forces (the F-14, F-15, F/A-18, and the AV-8B) and
international customers, as well as radars for the AC-130U gunship and the B-2
stealth bomber. SES is also part of a joint venture with Northrop Grumman
Corporation providing the next generation airborne radar for the F-22 aircraft.
The segment provides the Forward Looking Infrared (FLIR) and designation system
for the F-117 Stealth Fighter, the infrared subsystem for the F/A-18 targeting
pod, and is developing the Advanced Targeting FLIR for the F/A-18.

         SES supplies integrated sensor suites for applications such as the U.S.
Department of Defense's ("DoD") Global Hawk Unmanned Aerial Vehicle
Reconnaissance System, which includes a synthetic aperture radar and
electro-optical/infrared sensors. SES surveillance and reconnaissance systems
are used on a variety of aircraft, such as the British Tornado, the U.S. Air
Force U-2 and the U.S. Navy P-3 Orion. SES also provides space sensors for
defense and scientific applications.

         SES night vision and fire control systems equip combat vehicles like
the M1 Abrams tank, Bradley Fighting Vehicle and a host of light armored
vehicles, ships and submarines, and aircraft. The segment also puts state of the
art technology in the hands of the infantry. Its sensor and electronic systems
are used for law enforcement, security, oil spill response, search and rescue
and many other commercial and industrial applications. One anticipated
commercial night vision application is a night driving safety option on the
model year 2000 Cadillac(R) DeVille(R)(1).

(1)  Cadillac & DeVille are registered trademarks of General Motors Corporation.

         The segment's surface radar products include radars for
intelligence/data collection, spacetrack, deep space surveillance, missile
warning and imaging and command and control radars. Tactical radars include
battlefield radars for Forward Area Air Defense Systems and hostile weapons
locating radars.

         Command, Control, Communications and Information Systems. The Command,
Control, Communications and Information Systems segment ("C3I") is involved in
command, control and communication systems; air traffic control systems;
tactical radios; satellite communication ground control terminals; wide area
surveillance systems; advanced transportation systems; simulators and simulation
systems; ground-based information processing systems; large scale information
retrieval, processing and distribution systems; and global broadcast systems.


                                       6

         C3I is part of a team under contract to design, develop, integrate and
test the command, control, communications and intelligence sonar, combat control
and architecture subsystems for the U.S. Navy's next generation attack submarine
- - the New Attack Submarine or NSSN. The segment builds military communications
systems and also a family of Extended Environment (E(2)) COTS computers and
workstations.

         An example of C3I's capabilities in the area of advanced information
integration is the U.S. Navy's Cooperative Engagement Capability (CEC) program.
CEC provides the capability to integrate theater sensors and weapon systems
ships, aircraft and land-based installations into an integrated air picture. The
system has now successfully completed more than seven years of comprehensive
at-sea testing, including several live fire tests, and is now facing the
challenges of integration into the fleet. C3I also has capabilities in
large-scale image processing and advanced signal processing.

         C3I lead Raytheon's role as the prime contractor for the Brazilian
System for the Vigilance of the Amazon (SIVAM) program, which calls for the
delivery of an integrated information network linking numerous sensors to
regional and national coordination centers. Information will be used to protect
the environment, improve air safety and weather forecasts, help control
epidemics, manage land occupation and usage and ensure effective law enforcement
and border control.

         C3I also designs and installs air traffic control (ATC) and weather
systems at airports worldwide. One example is the FAA/DoD's Standard Terminal
Automation Replacement System (STARS) program, which will modernize and upgrade
approximately 370 air traffic control sites across the United States. Some of
the countries Raytheon is providing ATC systems and radars for include:
Australia, Canada, China, Cyprus, Germany, Hong Kong, India, Jamaica, The
Netherlands, Norway, Oman, Switzerland and Taiwan. Raytheon's Terminal Doppler
Weather Radar (TDWR) system is being installed at 42 sites across the United
States and Puerto Rico. The new Hong Kong airport is the first international
installation of Raytheon's TDWR system. TDWR uses Doppler radar technology to
warn air traffic controllers of sudden wind shifts, such as microbursts, which
have been blamed for numerous aircraft accidents, particularly during takeoff
and landing.

         Aircraft Integration Systems. The Aircraft Integration Systems segment
("AIS") focuses on integration of airborne surveillance and intelligence
systems; aircraft modifications; and head-of-state aircraft systems.

         AIS specializes in the design and installation of interiors for
executive and VIP/head-of-state aircraft. The segment also performs Special
Operations Forces Support Activity (SOFSA) and is working on the Airborne Early
Warning and Control (AEW&C) program. During 1998, Raytheon (through AIS)
continued the U.S. Air Force's C-141 avionics modernization program which
includes a "glass cockpit," a digital autopilot, an improved, integrated GPS
navigation system, and enhanced situational awareness systems.

Consolidations

         In January 1998, Raytheon announced plans to reduce the RSC workforce
by 8,700 employees and reduce facility space by approximately 8 million square
feet. In October 1998, the Company announced previously planned actions to
accelerate and expand these initiatives, thereby reducing employment by a total
of 12 percent by the end of 1998 and another 4 percent in 1999, for a total
reduction of 16 percent, or approximately 14,000 positions by the end of 1999.
RSC will also vacate an additional 2 million square feet at 8 facilities and
complete all facility related actions by the end of 1999 through sales,
subleases and lease termination. The principal actions involve the consolidation
of missile and other electronic systems manufacturing and engineering, as well
as the consolidation of certain component manufacturing, into Centers of
Excellence.

         In January 1998, Raytheon also announced plans to reduce the RE&C
workforce by 1,000 employees and close or partially close 16 offices, or
approximately 1.1 million square feet. Raytheon is reassessing the structure and
operations of this business, while implementing the previously announced cost
reduction initiatives. In the fourth quarter of 1998, the Company (i) modified
the plan announced in January 1998 to close fewer facilities and (ii) announced
plans for an additional 260 person reduction in the RE&C workforce.

                      SALES TO THE UNITED STATES GOVERNMENT

         Sales to the United States Government (the "Government"), principally
to the Department of Defense ("DoD"), were $12.827 billion in 1998 and $6.270
billion in 1997 representing 66.1% of total sales in 1998 and 46.1% in 1997.
Approximately $6.799 billion of the increase is due to the acquisition of
TI Defense and the merger with Hughes Defense. Of these sales, $1.660 billion in
1998 and $483 million in 1997 represented purchases made by the Government on
behalf of foreign governments.

of electronics systems or major components of such systems. Over its lifetime, a
program may be implemented by the award of many different individual contracts
and subcontracts. The funding of Government programs is subject to congressional
appropriations. Although multi-year contracts may be authorized in connection
with major procurements, Congress generally appropriates funds on a fiscal year
basis even though a program may continue for many years. Consequently, programs
are often only partially funded initially and additional funds are committed
only as Congress makes further appropriations. The Government is required to
adjust equitably a contract price for additions or reductions in scope or other
changes ordered by it.

         Generally, Government contracts are subject to oversight audits by
Government representatives and provisions permitting termination, in whole or in
part, without prior notice at the Government's convenience upon the payment of
compensation only for work done and commitments made at the time of termination.
In the event of termination, the contractor will receive some allowance for
profit on the work performed. The right to terminate for convenience has not had
any significant effect upon Raytheon's business in light of its total Government
business.

         The Company's Government business is performed under both cost
reimbursement and fixed price prime contracts and subcontracts. Cost
reimbursement contracts provide for the reimbursement of allowable costs plus
the payment of a fee. These contracts fall into three basic types: (i) cost plus
fixed fee contracts which provide for the payment of a fixed fee irrespective of
the final cost of performance; (ii) cost plus incentive fee contracts which
provide for increases or decreases in the fee, within specified limits, based
upon actual results as compared to contractual targets relating to such factors
as cost, performance and delivery schedule; and (iii) cost plus award fee
contracts which provide for the payment of an award fee determined in the
discretion of the customer based upon the performance of the contractor against
pre-established criteria. Under cost reimbursement type contracts, Raytheon is
reimbursed periodically for allowable costs and is paid a portion of the fee
based on contract progress. Some costs incident to performing contracts have
been made partially or wholly unallowable by statute or regulation. Examples are
charitable contributions, travel costs in excess of government rates and certain
litigation defense costs.

         The Company's fixed price contracts are either firm fixed price
contracts or fixed price incentive contracts. Under firm fixed price contracts,
Raytheon agrees to perform the contract for a fixed price and as a result
benefits from cost savings and carries the burden of cost overruns. Under fixed
price incentive contracts, Raytheon shares with the Government savings accrued
from contracts performed for less than target costs and costs incurred in excess
of targets up to a negotiated ceiling price (which is higher than the target
cost) and carries the entire burden of costs exceeding the negotiated ceiling
price. Under such incentive contracts, the Company's profit may also be adjusted
up or down depending upon whether specified performance objectives are met.
Under firm fixed price and fixed price incentive type contracts, the Company
usually receives progress payments monthly from the Government generally in
amounts equaling 75% and 80% of costs incurred under (i) DoD contracts and (ii)
all other Government contracts, respectively. The remaining amount, including
profits or incentive fees, is billed upon delivery and final acceptance of end
items under the contract.


                                       12

         The Company's Government business is subject to specific procurement
regulations and a variety of socio-economic and other requirements. Failure to
comply with such regulations and requirements could lead to suspension or
debarment, for cause, from Government contracting or subcontracting for a period
of time. Among the causes for debarment are violations of various statutes,
including those related to procurement integrity, export control, government
security regulations, employment practices, the protection of the environment,
the accuracy of records and the recording of costs.

         Under many Government contracts, the Company is required to maintain
facility and personnel security clearances complying with DoD requirements.

         Companies which are engaged in supplying defense-related equipment to
the Government are subject to certain business risks some of which are peculiar
to that industry. Among these are: the cost of obtaining trained and skilled
employees; the uncertainty and instability of prices for raw materials and
supplies; the problems associated with advanced designs, which may result in
unforeseen technological difficulties and cost overruns; and the intense
competition and the constant necessity for improvement in facilities and
personnel training. Sales to the Government may be affected by changes in
procurement policies, budget considerations, changing concepts of national
defense, political developments abroad and other factors.

         As a result of the 1985 Balanced Budget and Emergency Deficit Reduction
Control Act, the federal deficit and changing world order conditions, DoD
budgets have been subject to increasing pressure resulting in an uncertainty as
to the future effects of DoD budget cuts. Raytheon has, nonetheless, maintained
a solid foundation of tactical defense systems which meets the needs of the
United States and its allies, while serving a broad government program base and
wide range of commercial electronics businesses. These factors lead management
to believe that there is high probability of continuation of Raytheon's current
major tactical defense programs.

         See "Item 1. Business -- Sales to the United States Government" for
information regarding the percentage of the Company's revenues generated from
sales to the Government.

                                     BACKLOG

         The Company's backlog of orders at December 31, 1998 was $24.045
billion compared with $21.515 billion at the end of 1997. The 1998 amount
includes funded backlog of $14.622 billion from the Government compared with
$12.547 billion at the end of 1997. During the third quarter of 1998, Raytheon
changed its method of reporting backlog at certain locations in order to provide
a consistent method of reporting across and within Raytheon businesses. The
company includes the full value of contract awards when received, excluding
awards and options expected in future periods. Prior to the change, contract
values, which were awarded, but incrementally funded, were excluded from
reported backlog for some parts of the business. The one-time impact of this
change was a $1.1 billion increase to Electronics backlog and a $0.9 billion
increase to Engineering and Construction backlog, related principally to U.S.
government contracts. Prior periods have not been restated for this change.


                                       13

         Approximately $3.817 billion of the overall backlog figure represents
the unperformed portion of direct orders from foreign governments. Approximately
$2.556 billion of the overall backlog represents non-government foreign backlog.

         Backlog in the Engineering and Construction segment was $3.888 billion
at the end of 1998 compared with $2.900 billion at the end of 1997. Design and
construction contracts in this segment typically take from eighteen months to
several years to perform.

         Aircraft segment backlog was $2.509 billion at the end of 1998 versus
$1.974 billion at the end of 1997. The increase was primarily due to the receipt
of orders for general aviation aircraft including Horizon, Premier I and Hawker
800XP.

         Approximately $9.569 billion of the $24.045 billion 1998 year-end
backlog is not expected to be filled during the following twelve months.

                            RESEARCH AND DEVELOPMENT

         During 1998, Raytheon derived net sales of $4.372 billion ($2.115
billion in 1997 and $1.496 billion in 1996) pursuant to Government contracts for
research and development. In addition, during 1998 Raytheon expended $582.1
million on research and development efforts compared with $415.1 million in 1997
and $323.3 million in 1996. These expenditures principally have been for product
development for the Government and for aircraft products.

                                   SUPPLIERS

         Delivery of raw materials and supplies to Raytheon is generally
satisfactory. Raytheon is sometimes dependent, for a variety of reasons, upon
sole-source suppliers for procurement requirements. However, Raytheon has
experienced no significant difficulties in meeting production and delivery
obligations because of delays in delivery or reliance on such suppliers. See
Management's Discussion and Analysis of Financial Condition and Results of
Operations on pages 28 through 32 of the Company's Annual Report to Stockholders
for the year ended December 31, 1998 for information regarding the "Year 2000"
issue as it relates to the Company and the Company's suppliers.

                                   COMPETITION

         The military and commercial industries in which Raytheon operates are
highly competitive. Raytheon's competitors range from highly resourceful small
concerns, which engineer and produce specialized items, to large, diversified
firms.

         The Electronics businesses are a direct participant in most major areas
of development in the defense, space, information gathering, data reduction and
automation fields. Technical superiority and reputation, price, delivery
schedules, financing and reliability are among the principal competitive factors
considered by electronics customers. The ongoing consolidation of the U.S. and
global defense, space and aerospace industries continues to intensify
competition. Consolidation among U.S. defense, space and aerospace companies has
resulted in three principal prime contractors for the DoD, including the
Company. As a result of this consolidation, the Company frequently partners on
various programs with its major suppliers, some of whom are, from time to time,
competitors on other programs.


                                      14

         Competition in the Engineering and Construction segment comes from a
number of domestic and foreign firms, competing for major business opportunities
worldwide. In addition to numerous small and specialty firms, there are nine
large competitors to the Company in this industry. Competition is based
primarily upon performance, technical skills, experience, reliability,
financing, and price. The ability to recruit and maintain highly skilled and
experienced professionals has a critical impact on the Company's competitiveness
in this industry. The industry's intense competition, particularly on contracts
that are competitively bid, can negatively impact price and margins. The Company
believes that the diversity of our customer base is a competitive strength.

         The Aircraft segment competes primarily with four other companies in
the business aviation industry. The principal factors for competition in the
industry are price, financing, operating costs, product liability, cabin size
and comfort, product quality, travel range and speed, and product support.
The Company believes we possess competitive advantages in the breadth of our
product line, the performance of our product line, and the strength of our
product support.


                             PATENTS AND LICENSES

         Raytheon has long been an innovative leader in the development of new
products and manufacturing technologies. Raytheon and its subsidiaries own a
large number of United States and foreign patents and patent applications as
well as trademark, copyright and semiconductor chip mask work registrations
which are necessary and contribute significantly to the preservation of the
Company's strong competitive position in the market. In certain instances,
Raytheon has augmented its technology base by licensing the proprietary
intellectual property of others.

         Raytheon's patent position and intellectual property portfolio is
deemed adequate for the conduct of its businesses. It is Raytheon's policy to
enforce its own intellectual property rights and to respect the rights of
others. Incidental to the normal course of business, infringement claims may
arise or may be threatened both by and against Raytheon. In the opinion of
management, these claims will not have a material adverse affect on the
Company's operations.

         Although these patents and licenses are, in the aggregate, important to
the operation of the Company's business, no existing patent, license or similar
intellectual property right is of such importance that its loss or termination
would, in the opinion of management, have a material effect on the Company's
business.

                                  EMPLOYMENT

         As of December 31, 1998, Raytheon had approximately 108,200 employees
compared with approximately 119,200 employees at the end of 1997. The decrease
is mainly due to layoffs within Raytheon Systems Company and RE&C, divestitures
of Seiscor, BSG/Remco, Commercial Laundry and Raytheon Aircraft Company Montek,
offset by the acquisition of the Communications Division of Allied Signal, Inc.
See "Part I, Divestitures and Acquisitions." Subsidiaries of Raytheon Engineers
& Constructors International, Inc. and certain other subsidiaries have craft
employees engaged for individual projects not included in Raytheon's employee
count.

         Raytheon considers its union-management relationships to be
satisfactory. Raytheon has, for the most part, successfully negotiated labor
agreements without significant work stoppages, with the exception of a nine week
strike that occurred during the summer of 1996 at the Cedar Rapids, Inc.
facility located in Cedar Rapids, Iowa. Raytheon currently has collective
bargaining relationships with 13 different labor organizations involving
39 separate labor agreements.


                                       15

                              INTERNATIONAL SALES

         Of total sales, Raytheon's sales to customers outside the United States
(including foreign military sales) were 26%, 29% and 28% in 1998, 1997 and 1996,
respectively. These sales were principally in the fields of air defense systems,
air traffic control systems, sonar systems, aircraft products, petrochemical,
power and industrial plant design and construction, electronic equipment,
computer software and systems, personnel training, equipment maintenance and
microwave communication. Although international sales as a percentage of
Raytheon's total sales decreased slightly from 1997 to 1998 (primarily due to
the merger of Hughes Defense and acquisition of TI Defense), it is anticipated
that, consistent with the Company's goals, such percentage of international
sales will increase. Foreign subsidiary working capital requirements generally
are financed in the countries concerned. Sales and income from international
operations are subject to changes in currency values, domestic and foreign
government policies (including requirements to expend a portion of program funds
in-country) and regulations, embargoes and international hostilities. Exchange
restrictions imposed by various countries could restrict the transfer of funds
between countries and between Raytheon and its subsidiaries. Raytheon generally
has been able to protect itself against most undue risks through insurance,
foreign exchange contracts, contract provisions, government guarantees or
progress payments.

         Raytheon utilizes the services of sales representatives and
distributors in connection with foreign sales. Normally representatives are paid
commissions and distributors are granted resale discounts in return for services
rendered.

         Licenses are required from Government agencies under the Export
Administration Act, the Trading with the Enemy Act of 1917 and the Arms Export
Control Act of 1976 (formerly the Foreign Military Sales Act) for export from
the United States of many of Raytheon's products. In the case of certain sales
of defense equipment and services to foreign governments, the Government's
Executive Branch must notify Congress at least 15 to 30 days (depending on the
location of the sale) prior to authorizing such sales. During that time,
Congress may take action to block the proposed sale.

foreign customers to finance purchases, (iii) uncertainties and restrictions
concerning the availability of funding credit or guarantees, (iv) changing
military and political alliances, (v) U.S. or foreign export controls and trade
restrictions, (vi) government policies with respect to restrictions on doing
business with certain countries, (vii) governmental industrial cooperation
requirements, (viii) foreign exchange risks, (ix) increased international
competition and cross-border consolidation of competition, (x) the adequacy and
availability of transportation, (xi) the complexity and necessity of using
foreign representatives and consultants and (xii) the uncertainty of complying
with the laws of specific countries and of U.S. laws affecting the activities of
U.S. companies abroad.

         In the commercial electronics segment, important factors that may cause
actual results to differ materially include, in addition to those noted above,
(i) product demand, including continued expansion of the satellite
telecommunications and telecommunications systems markets and (ii) consumer
spending patterns affecting recreational boat sales and favorable economic
conditions for commercial marine products and sales.

         Engineering and Construction Segment. In the engineering and
construction segment, important factors that could cause actual results to
differ materially include, in addition to those noted above, (i) the effects of
global, regional and country-specific economic conditions in light of our
business and international backlog, (ii) performance risks for existing and
future contracts, (iii) conditions in the capital markets and the availability
of project financing, (iv) international political and labor conditions, (v) the
timing of contract receipt and funding, (vi) the availability of infrastructure
funding for improvements to U.S. highways and (vii) the ability of the Company
to successfully implement its consolidation and cost reduction plans for RE&C.


                                      17

         Aircraft Segment. In the aircraft segment, important factors that could
cause actual results to differ materially include, in addition to those noted
above, (i) market perceptions of and government regulations affecting regional
aircraft, (ii) government legislation affecting aviation, such as user fees,
(iii) price pressures within the market, (iv) the ability to meet scheduled
timetables for the introduction of new products, (v) delays in U.S. Government
export approvals and (v) third party financing availability.

         Consolidation and Reorganization of Raytheon Systems Company. The
Company continues its consolidation and reorganization of Raytheon Systems
Company. However, the Company may encounter difficulties or may not realize the
full benefits expected from such integration. The success of Raytheon Systems
Company will require, among other things, the continued execution of the
consolidation and reorganization planned. The challenges include the integration
of numerous geographically separated manufacturing facilities and research and
development centers. The success of this plan will be significantly influenced
by the Company's ability to retain key employees, to integrate differing
management structures and to realize anticipated cost synergies, all of which
will require significant management time and resources. Any material delays or
unexpected costs incurred in connection with such integration could have a
material adverse effect on the Company's business, operating results or
financial condition and there can be no assurance that additional restructuring
actions will not be required.

         Contract Accounting. Contract accounting requires the use of estimates
in determining progress toward completion in order to record revenue and profit
in the current period. This process includes the ongoing evaluation of risks and
uncertainties inherent in the performance of contracts. Since many contracts
extend over a long period of time, revisions in estimates may have the effect of
adjusting earnings in the current period that are applicable to performance in
prior periods.

         Year 2000 Data Conversion. While the Company expects to resolve all
Year 2000 risks without material adverse impact on results of operations,
liquidity, or financial condition, important factors that could cause actual
results to differ materially include (i) the Company's ability to detect all
Year 2000 problems, (ii) the Company's ability to achieve successful and timely
resolution of all Year 2000 issues, and (iii) the preparedness of the Company's
critical suppliers to avoid Year 2000 related service and delivery
interruptions.

         See Management's Discussion and Analysis of Financial Condition and
Results of Operations on pages 28 through 32 of the Company's Annual Report to
Stockholders for the year ended December 31, 1998 for information regarding the
Company's efforts with respect to Year 2000 issues and status thereof.

Item 2.  Properties

         The Company and its subsidiaries operate in a number of plants,
laboratories, warehouses and office facilities in the United States and abroad.

         At December 31, 1998, the Company utilized approximately 53 million
square feet of floor space for manufacturing, engineering, research,
administration, sales and warehousing, approximately 95% of which was located in
the United States. Of such total, approximately 40% was owned, approximately 55%
was leased, and approximately 5% was made available under facilities contracts
for use in the performance of United States Government contracts. At December
31, 1998 the Company had approximately 3.3 million square feet of additional
floor space that was not in use, including approximately 2 million square feet
in Company-owned facilities.


                                      18

         There are no major encumbrances on any of the Company's plants or
equipment other than financing arrangements which in the aggregate are not
material. In the opinion of management, the Company's properties have been well
maintained, are in sound operating condition and contain all equipment and
facilities necessary to operate at present levels.

         A summary of the utilized floor space at December 31, 1998, by
business segment, follows:

environmental protection requirements and the resolution of environmental claims
against the Company and its operations.

Item 3.  Legal Proceedings

         Prior to the Hughes Merger, the business of Hughes Defense was
conducted by Hughes Aircraft Company ("HAC"), an indirect subsidiary of Hughes
Electronics Corporation. Since 1985, several actions seeking compensatory and
punitive damages in unspecified amounts have been filed against HAC by
plaintiffs alleging that they suffered injuries as a result of the migration of
alleged toxic substances into the Tucson, Arizona, water supply. These
substances were disposed of at a facility owned by the United States Government
which HAC operated and Raytheon now leases under a contract with the U.S. Air
Force.

         In 1991, HAC settled with the approximately 2,000 plaintiffs in one of
these cases, Valenzuela v. Hughes Aircraft Company. HAC's primary and excess
insurance carriers made substantial contributions toward this settlement.
Several of these carriers are seeking reimbursement of the amounts they paid. If
the insurers prevail in the insurance coverage litigation, the Company may
ultimately bear responsibility for a portion of the Valenzuela settlement.

         Several other actions arising out of migration of alleged toxic
substances into the Tucson water supply are still pending, including:


                                      19

1.   Cordova v. Hughes Aircraft Company, et al., which was filed on January 13,
     1992, with the Arizona Superior Court, Pima County by an estimated 90,000
     member class against HAC, McDonnell Douglas Corporation, General Dynamics
     Corporation and the Tucson Airport Authority as co-defendants. The court
     denied class certification in 1996. Settlement was reached with all but 3
     claimants in 1998. Such remaining claims were dismissed, the dismissal of
     which are now on appeal.

2.   Yslava v. Hughes Aircraft Company, an action filed on August 7, 1992, in
     U.S. District Court for the District of Arizona by approximately 250
     individual plaintiffs, alleging injury claims (inclusive of loss of
     consortium claims). HAC filed third party claims against McDonnell Douglas
     Corporation, General Dynamics Corporation, the Tucson Airport Authority and
     the City of Tucson.

3.   Lanier v. Hughes Aircraft Company, et al., a class action filed on
     September 30, 1991, in U.S. District Court for the District of Arizona
     seeking medical monitoring for an estimated class of 50,000 residents from
     the south side of Tucson.

         The Company is vigorously defending these actions, and believes both
that it has strong defenses to the claims asserted against it and that it has
claims for contribution against other entities. In addition, the Company has
obtained state and federal court decisions requiring its insurers to pay defense
costs in these actions. Although the Company believes that it has good bases for
seeking indemnity coverage from its carriers, it cannot reasonably estimate
what, if any, coverage may, in fact, be available.

         The Company is also involved in various stages of investigation and
cleanup relative to remediation of various other sites. All appropriate costs
incurred in connection therewith have been accrued. Due to the complexity of
environmental laws and regulations, the varying costs and effectiveness of
alternative cleanup methods and technologies, the uncertainty of insurance
coverage and the unresolved extent of the Company's responsibility, it is
difficult to determine the ultimate outcome of these matters. However, in the
opinion of management, any liability will not have a material effect on the
Company's financial position, liquidity or results of operations after giving
effect to provisions already recorded.

         Accidents involving personal injuries and property damage occur in
general aviation travel. When permitted by appropriate government agencies,
Raytheon Aircraft investigates accidents related to its products involving
fatalities or serious injuries. Through a relationship with FlightSafety
International, Raytheon Aircraft provides initial and recurrent pilot and
maintenance training services to reduce the frequency of accidents involving its
products.

         Raytheon Aircraft is a defendant in a number of product liability
lawsuits which allege personal injury and property damage and seek substantial
recoveries including, in some cases, punitive and exemplary damages. Raytheon
Aircraft maintains partial insurance coverage against such claims and maintains
a level of uninsured risk determined by management to be prudent. (See Note L to
Raytheon's Financial Statements for the years ended December 31, 1998, 1997 and
1996.)


                                      20

         The insurance policies for product liability coverage held by Raytheon
Aircraft do not exclude punitive damages, and it is the position of Raytheon
Aircraft and its counsel that punitive damage claims are therefore covered.
Historically, the defense of punitive damage claims has been undertaken and paid
by insurance carriers. Under the law of some states, however, insurers are not
required to respond to judgments for punitive damages. Nevertheless, to date no
judgments for punitive damages have been sustained.

         Defense contractors are subject to many levels of audit and
