ITEMS 1. AND 2. BUSINESS AND PROPERTIES
 
                        GENERAL DEVELOPMENT OF BUSINESS
 
  Atlantic Richfield Company ("ARCO," the "Company" or the "Corporation") was
incorporated in 1870 under the laws of Pennsylvania as The Atlantic Refining
Company. Atlantic Petroleum Storage Company, a predecessor to The Atlantic
Refining Company, began operations in 1866. The Company's principal executive
offices are at 515 South Flower Street, Los Angeles, California 90071
(Telephone (213) 486-3511). ARCO's present name was adopted subsequent to the
merger of Richfield Oil Corporation into The Atlantic Refining Company in
1966. In 1969, Sinclair Oil Corporation was merged into ARCO. In 1977, The
Anaconda Company was merged into a wholly owned subsidiary of ARCO and, on
December 31, 1981, that subsidiary was merged into ARCO. On May 7, 1985, ARCO
was reincorporated in the State of Delaware. Unless indicated otherwise, the
terms "ARCO," the "Company" or the "Corporation" as used herein refer to
Atlantic Richfield Company or Atlantic Richfield Company and one or more of
its consolidated subsidiaries.
 
                 FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS
 
  Reference is made to Note 4 of Notes to Consolidated Financial Statements on
page 43 for segment information concerning sales and other operating revenues,
earnings, total assets and additional information for certain operations of
the Company.
 
                        SUMMARY DESCRIPTION OF BUSINESS
 
  ARCO, including its subsidiaries, constitutes one of the largest integrated
enterprises in the petroleum industry, with its principal operations conducted
in the United States. ARCO conducts operations in two business segments:
resources and products. ARCO also owns a 49.9 percent equity interest in
Lyondell Petrochemical Company ("Lyondell"), which operates petrochemical and
petroleum processing businesses.
 
  ARCO's resources segment includes the exploration, development and
production of petroleum, which includes petroleum liquids (crude oil,
condensate and natural gas liquids ("NGLs")) and natural gas, the purchase and
sale of petroleum liquids and natural gas, and the mining and sale of coal.
The exploration, development and production of all of ARCO's oil and gas
interests in the State of Alaska and surrounding offshore waters are conducted
through a wholly owned subsidiary, ARCO Alaska, Inc. ("ARCO Alaska"). The
exploration, development and production of ARCO's oil and gas interests in
foreign countries are conducted through the ARCO International Oil and Gas
division ("ARCO International"). The mining and marketing of coal from surface
and underground mines located in the western United States and in Australia
are conducted through the ARCO Coal division ("ARCO Coal").
 
  In October 1993, ARCO reorganized the ARCO Oil and Gas division, which
operated ARCO's Lower 48 exploration, development, production and marketing
activities. The cornerstone of ARCO's program to reorganize its Lower 48
operations is Vastar Resources, Inc. ("Vastar"), which on a stand alone basis
is one of the largest independent (non-integrated) oil and gas companies in
the United States. Vastar is engaged in the exploration for and the
development and production of natural gas and, to a lesser extent, crude oil
in selected major producing basins in the Gulf of Mexico, the Gulf Coast, the
San Juan Basin and the Mid-Continent areas. ARCO conducts its other operations
in the Lower 48 through its ARCO Permian business unit ("ARCO Permian"), which
exploits long-lived producing fields in the Permian and East Texas basins; its
ARCO Western Energy business unit
 
                                       1
<PAGE>
 
("ARCO Western Energy"), which focuses on oil production primarily from five
producing oil fields in California and related cogeneration operations; and
ARCO Long Beach Inc., a wholly-owned subsidiary ("ALBI"), which manages the
optimized waterflood program for the Long Beach unit of the Wilmington Field
pursuant to a contractual arrangement with the State of California and the
City of Long Beach.
 
  ARCO's products segment includes the refining and transportation of
petroleum and petroleum products, the marketing of petroleum products on the
West Coast and the manufacture and sale of intermediate chemicals and
specialty products. The ARCO Products division ("ARCO Products") is a refiner
and marketer of refined petroleum products on the West Coast. ARCO Chemical
Company, a subsidiary of which ARCO owns 83.3 percent ("ARCO Chemical"),
produces and markets on a worldwide basis certain intermediate chemicals and
specialty products, including propylene oxide and its derivatives, tertiary
butyl alcohol and its derivatives, and styrene monomer and its derivatives.
The ARCO Transportation division ("ARCO Transportation") operates domestic
facilities for the transportation and storage of petroleum liquids, refined
petroleum products, petrochemicals and natural gas.
 
                              RECENT DEVELOPMENTS
 
  On January 17, 1994, at about 4:30 a.m., Southern California experienced a
major earthquake that caused widespread property damage and major disruptions
to utilities and highways. While ARCO's Los Angeles and Long Beach
headquarters buildings and Los Angeles Refinery did not suffer any discernible
damage, certain of ARCO's other assets located in the region experienced
varying degrees of damage. One of ARCO's common carrier crude oil pipelines
suffered ruptures; ARCO temporarily closed all of its pipelines in Southern
California to assess damage. Nearly 70 ARCO-branded service stations
throughout the region experienced damage; all but one are now back in
operation. ARCO does not believe that the aggregate damage it suffered will
have a material adverse effect on its financial position or operations.
 
  On January 28, 1994, Vastar, ARCO's wholly-owned subsidiary, filed a
registration statement on Form S-1 with the Securities and Exchange Commission
for the proposed sale of up to 17,250,000 shares of common stock to the
public. ARCO intends to retain 80,000,001 shares, or 82.3 percent of Vastar's
common stock. ARCO has a continuous, cumulative option to purchase from
Vastar, at then current market prices, such number of shares of stock as will
permit ARCO to continue to include Vastar in its consolidated federal income
tax return. ARCO will be in a position to continue to elect Vastar's board of
directors and to control the affairs of the company.
 
                                   RESOURCES
 
OIL AND GAS
 
  Following the 1993 reorganization of its Lower 48 operations, ARCO conducts
oil and gas exploration and production primarily through a number of business
units, which are either wholly-owned subsidiaries or divisions of ARCO. ARCO
Alaska is responsible for exploration, development and production of all of
ARCO's oil and gas interests in the State of Alaska and surrounding offshore
waters, of which the principal producing properties are interests in the
Prudhoe Bay field, the Kuparuk River field and the Greater Point McIntyre
area. As previously described, ARCO's principal Lower 48 operations are
conducted by Vastar; the remainder of its Lower 48 operations are conducted
through ARCO Permian, ARCO Western Energy and ALBI. ARCO International is
responsible for exploration, development and production of ARCO's oil and gas
interests overseas. In addition, Vastar, ARCO Permian, and ARCO International
are responsible for marketing oil and gas production, and for crude oil,
natural gas and NGLs purchases, resales and locational exchanges to reduce
transportation costs.

  Reference is made to Supplemental Information, Oil and Gas Producing
Activities, beginning on page 54, for additional information concerning oil
and gas producing activities and estimates of proved oil and gas reserves.
 
  In 1993 and 1992, ARCO produced approximately 147 percent and 158 percent,
respectively, of the crude oil requirements for its two West Coast refineries.
Of the excess production, a portion was delivered to a refinery owned by Tosco
Corporation ("Tosco") under a long-term supply agreement, some was sold to
Lyondell and the significant remainder was sold on the open market. See
"Products--Refining and Marketing."
 
  Net quantities of petroleum liquids and natural gas produced by ARCO were as

  Delivery commitments covering natural gas production are as follows:
 
  In the United States, the Company has various long-term natural gas sales
contracts. Certain contracts are reservoir dedicated, and present no
obligation to deliver if production from these reservoirs ceases. Deliveries
under such contracts comprised approximately 70 billion cubic feet in 1993 and
will decline to approximately 18 billion cubic feet by 1995.
 
  Additional long-term domestic contracts, with terms varying from 1 to 20
years, had delivery commitments of approximately 174 billion cubic feet in
1993. The majority of these contracts are index based and present little or no
price risk. Deliveries under these existing long-term contracts will increase
to approximately 285 billion cubic feet annually in 1995. The Company can
satisfy its existing natural gas delivery commitments from proprietary
domestic production in the Lower 48. Total proprietary domestic production,
which includes associated royalty volumes, was 367 billion cubic feet in 1993.
The
 
                                       3
<PAGE>
 
Company reported 4,725 billion cubic feet of domestic proved natural gas
reserves at December 31, 1993. There have been no instances in the last three
years in which the Company was unable to meet its natural gas delivery
commitments.
 
  Overseas, the Company has various long-term natural gas sales contracts. The
majority of ARCO's natural gas production from the North Sea and its
Indonesian operations is committed under long-term sales agreements. While
annual delivery requirements may vary under these contracts, delivery
obligations under the agreements are essentially limited to producible
reserves from specific fields.
 
 ARCO Alaska, Inc.
 
  During 1993, approximately 69 percent of ARCO's domestic petroleum liquids
production came from the Prudhoe Bay, Kuparuk River and the Greater Point
McIntyre area fields on the North Slope of Alaska. While ARCO Alaska's net
liquids production was down 20,200 barrels per day from 1992 to 418,700
barrels per day in 1993 as a result of natural field decline, production is
expected to increase in 1994 as a full year's benefit from the new Point
McIntyre field and the first phase of Prudhoe Bay's second major gas handling
expansion facility ("GHX-2") is recognized.
 
  ARCO Alaska operates the eastern half of the Prudhoe Bay field and has a
21.78 percent working interest in the oil produced from the field, a 42.56
percent working interest in the condensate produced and, in 1993, a 37.7
percent working interest in the NGLs produced. ARCO's net petroleum liquids
production from the Prudhoe Bay field averaged 250,800 barrels per day in
1993, compared to 270,500 barrels per day in 1992, the result of natural field
decline. The first phase of GHX-2, which started up in September 1993,
increased gas handling capacity to an average 6.7 billion cubic feet per day
in the fourth quarter. The GHX-2 project, a joint undertaking among the
working interest owners, is designed to increase the field's average gas
handling capacity, and thereby mitigate declining oil production. Pursuant to
an agreement reached among ARCO Alaska and the working interest owners of the
Prudhoe Bay field in 1990, the owners committed to invest approximately $1.3
billion in additional gas handling facilities. Upon full implementation,
expected in late 1994, the GHX-2 project is expected to increase gas handling
capacity to 7.5 billion cubic feet per day and provide gross liquids
production benefits of approximately 100,000 barrels per day.
 
  ARCO Alaska is the sole operator of the Kuparuk River field and holds a
55.17 percent working interest in the field. Its share of production from the
field was 151,500 net barrels per day of petroleum liquids during 1993,
compared to 150,800 net barrels per day during 1992 when ARCO was in an equity
payback position for the first part of the year. Natural field decline has
been offset at Kuparuk through continued peripheral development and infill
drilling, as well as downhole fracturing and refracturing programs and
expansion of enhanced oil recovery processes.
 
  The Greater Point McIntyre area encompasses the Point McIntyre, Lisburne,
and the smaller West Beach and North Prudhoe Bay State fields. ARCO operates
the Lisburne field, which has been producing since 1986, with production
averaging 9,300 net barrels of liquids per day in 1993. The three other
fields, which recently began production, are all produced through the Lisburne
field facilities. Point McIntyre, the largest of the four fields in the area,
with approximately 94 million net barrels of proved reserves, started up in
October 1993 and averaged 25,400 net barrels per day for the remainder of the
year. One well at the West Beach field was brought on line in April 1993 and
one well from the North Prudhoe Bay State reservoir began production in
October 1993. By December 1993, liquids produced through the Lisburne
Production Facility averaged 135,200 gross barrels per day, and 42,700 net
barrels per day. ARCO Alaska holds a 30.1 percent working interest in Point
McIntyre, a 40 percent interest in Lisburne, a 50 percent interest in West
Beach and a 50 percent interest in North Prudhoe Bay State.
 
  ARCO Alaska maintained an active exploration and delineation program in
1993, participating in 13 wells. One well was announced as a discovery, the
North Prudhoe Bay State #3. Following further
 
                                       4
<PAGE>
 
delineation work on the 1991 Sunfish discovery, ARCO and its partner reported
at least one more season of drilling will be required to determine the amount
of reserves in the field. Delineation drilling in the northern part of the
Sunfish structure is continuing following the completion of one well in 1993.
In the southern part of the prospect, no further drilling is planned following
the completion of two unsuccessful wells in 1993. ARCO Alaska holds a 60
percent working interest in the Sunfish prospect. In the Beaufort Sea, east of
Prudhoe Bay, ARCO and its partners drilled two delineation wells on the Kuvlum
prospect, where a discovery was made in 1992. While a substantial accumulation
of hydrocarbons was confirmed, the discovery is not commercial as a stand-
alone development. A well drilled in the adjacent Wild Weasel prospect did not
encounter commercial hydrocarbons.
 
  All petroleum liquids shipped from the North Slope fields are transported to
market through the Trans Alaska Pipeline System ("TAPS") to terminal
facilities at Valdez, and from there to West Coast locations by ocean-going
tankers.
 
 Lower 48
 
  During 1993, ARCO's Lower 48 operations had net production of 321 billion
cubic feet of natural gas and 68 million barrels of petroleum liquids as
compared to 425 and 81 in 1992, respectively. Reserves were reduced by 173
million barrels of oil equivalent, primarily due to production and property
divestitures. Development and exploration activities replaced 41 percent of
1993 net production.
 
  ARCO began in late 1991 to re-evaluate its Lower 48 operations in order to
reduce overhead and lease operating costs, to upgrade its property portfolio
and to achieve a better economic return on its exploration and development
spending. During the period 1991-1993, ARCO took various steps to achieve
these goals, culminating in its October 1993 reorganization of its Lower 48
operations. This reorganization resulted in the creation of four discrete
business units to operate ARCO's Lower 48 properties. Each of these four
business units has its own assets, operations and business strategies. ARCO
believes that this reorganization will enable these units to operate with a
lower overhead cost profile, a flatter organizational structure and a more
focused resource exploitation.
 
  Vastar, headquartered in Houston, Texas, is engaged in the exploration for
and the development, production and marketing of natural gas and, to a lesser
extent, crude oil in selected major producing basins in the Gulf of Mexico,
the Gulf Coast, the San Juan Basin and the Mid-Continent areas. At December
31, 1993, Vastar had net proved reserves of 423 million barrels of oil
equivalent, of which 78 percent were natural gas. 1993 net production averaged
161,000 barrels of oil equivalent per day.
 
  Vastar has entered into fixed for floating swap agreements under which 350
million cubic feet per day of natural gas production from various Vastar
properties is hedged at an average fixed price of $2.25 per thousand cubic
feet. These hedges cover approximately 50 percent of Vastar's production for
the period from March through December 1994.
 
  ARCO Permian, headquartered in Midland, Texas, owns producing fields in the
Permian and East Texas oil fields. Its proved reserves as of December 31, 1993
were 336 million barrels of oil equivalent, of which 75 percent were petroleum
liquids. 1993 net production averaged 81,000 barrels of oil equivalent per
day.
 
  ARCO Western Energy, headquartered in Bakersfield, California, operates five
producing oil fields in California, the largest being the Midway-Sunset field.
Its assets also include cogeneration operations in three of the fields, as
well as conventional steam-generating facilities. ARCO Western Energy had
proved reserves as of December 31, 1993, of 173 million barrels of oil
equivalent, of which 96 percent was petroleum liquids. 1993 net production
averaged 44,000 barrels of oil equivalent per day.
 
  ALBI, headquartered in Long Beach, California, manages the development of
the optimized waterflood program, begun in 1992, for the Long Beach Unit
portion of the Wilmington Field. Under ALBI's contractual arrangement with the
State of California and the City of Long Beach, ALBI receives
 
                                       5
<PAGE>
 
half of any profits above an agreed base profit level. In addition, THUMS Long
Beach Company, the operating company responsible for the day to day operations
of the unit under the direction and control of the City of Long Beach, is a
wholly owned subsidiary of ALBI. ALBI had proved reserves as of December 31,
1993 of 122 million barrels of oil equivalent. 1993 net production averaged
23,000 barrels of oil equivalent per day.
 
  As a part of the reorganization of its Lower 48 operations, ARCO decided to
close its Dallas headquarters; however, a transition team will remain in place
in the Dallas area for an extended period. This team will provide certain
transition services to, and will manage the disposition of assets not
allocated to, these four units. Such assets include certain improved real
estate, undeveloped leasehold property, and fee lands which do not conform to
the reorganized operations.
 
  In connection with the reorganization of its Lower 48 oil and gas
exploration and production operations, ARCO recorded a charge against fourth
quarter 1993 earnings of $450 million after tax. Included in the charge are
costs related to write-downs for sale or other disposition of certain oil and
gas properties and excess office space and the severance of approximately
1,300 employees.
 
 ARCO International Oil and Gas Company
 
  ARCO International's principal operations are in the North Sea, Indonesia
and Dubai. Foreign petroleum liquids production comes from Indonesia, the
United Kingdom, Dubai and Turkey. Foreign natural gas production comes from
the United Kingdom, Indonesia and the Netherlands. In 1993, principal foreign
exploration activities were conducted in Indonesia, the United Kingdom, China
and Algeria.
 
  In August 1993, the Orwell gas field in the U. K. sector of the North Sea
began production; for the fourth quarter of 1993 it averaged 49 million net
cubic feet of gas per day. ARCO British Limited operates and holds a 50
percent working interest in the field. In addition, the Murdoch gas field in
the U. K. sector of the North Sea began production in October 1993. Initial
production averaged 45 million net cubic feet of gas per day during the fourth
quarter. The Murdoch Field is partner-operated, with ARCO holding a 34 percent
working interest.
 
  ARCO International became a significant offshore gas producer in Indonesia
in 1993, following completion of two developments. In September 1993,
production and sale of natural gas began from a new gas development in the
Offshore Northwest Java contract area in Indonesia. ARCO has a 46 percent
interest in the contract area, where production is expected to average 260
million gross cubic feet per day in 1994. In January 1994, a second major gas
project in Indonesia, the Pagerungan gas project north of Bali, began initial
production. During 1994, the Pagerungan gas field is expected to produce 300
million gross cubic feet of gas per day. This gas is transported via a third
party pipeline to a local power generation plant and local users. ARCO is
operator and currently holds a 54 percent working interest.
 
  Development of the Yacheng 13-1 natural gas field in China continued on
schedule in 1993. The fabrication of the process and wellhead platforms is
underway and the installation of the undersea gas pipeline began in December
1993. The installation of the wellhead platform is scheduled for March 1994
and developmental drilling activities are expected to begin in May 1994. ARCO
will be the operator and will hold a 34.3 percent working interest in the
project. Gross production at the rate of 330 million cubic feet per day is
expected to start up in early 1996, and is to be sold to customers in Hong
Kong and on Hainan Island for power generation and other uses.
 
  In early 1992, ARCO International and its partner Agip announced an oil
discovery in Ecuador. During 1993, an extension of the exploration license for
this block was granted by the Ecuadorian government. Efforts are currently
underway on commercialization and development plans and at year-end a third
well was in progress.
 
 
                                       6

  ARCO International entered into several new exploration arrangements during
1993 in the United Kingdom, Indonesia, China, and Tunisia. ARCO British
Limited was awarded six North Sea licenses in the 14th Licensing Round in June
of 1993. Seismic options were acquired in eleven blocks in the Celtic Sea off
the coast of Ireland and two offshore blocks in the Philippines. In China,
drilling has begun on one of the two newly acquired blocks adjacent to the
Yacheng gas field and pipeline route in the South China Sea.
 
  ARCO International's net proved reserves increased 22 million barrels of oil
equivalent in 1993, primarily as a result of the Sirasun gas discovery in
Indonesia.

COAL
 
  ARCO Coal, headquartered in Denver, Colorado, operates mines in the western
United States and in northeastern Australia. ARCO Coal is owner and operator
of two surface mines in Wyoming's Powder River Basin, Black Thunder and Coal
Creek, that produce low sulfur steam coal. During 1993, the start-up of a
third dragline at Black Thunder completed the mine's transition from a truck-
and-shovel operation to a dragline operation. This start-up enabled Black
Thunder to achieve record shipments of 34.3 million tons in 1993. ARCO Coal
also owns and operates West Elk, an underground longwall mine in the Uinta
Basin in western Colorado that produces low sulfur, high BTU steam coal. West
Elk achieved record shipments of 3.0 million tons in 1993. In early 1994, ARCO
Coal acquired the Jumbo Mountain lease adjacent to the West Elk mine. The new
lease holds an estimated 10 million tons of recoverable reserves. Total U.S.
coal shipments for 1993 were 37.5 million tons of coal.
 
  ARCO Coal has interests in three mines in the Bowen Basin of Queensland,
Australia. ARCO Coal has an effective 87 percent interest in Curragh and a
31.4 percent interest in Blair Athol, both surface mines. Curragh produces
high-grade coking and steam coal, while Blair Athol produces only steam coal.
Curragh and Blair Athol had record shipments of 5.5 million net tons and 3.4
million net tons, respectively, in 1993. In December 1993, ARCO and the
operator of Blair Athol signed an agreement to acquire 55 percent of the
nearby undeveloped Clermont Project, which includes estimated gross reserves
of approximately 200 million tons of steam coal. ARCO Coal also operates and
has an 80 percent interest in Gordonstone, a state-of-the-art underground
longwall mine that began production of high-grade coking and steam coal in the
first half of 1993. ARCO Coal's net share of total shipments in 1993 from
Australian operations was 10.2 million tons.
 
  As of December 31, 1993, ARCO Coal had long-term domestic contracts to
supply U.S. utility companies with steam coal from its Black Thunder and Coal
Creek mines. These contracts have various termination dates with the longest
being December 31, 2017 and the earliest being April 30, 1994. Several of
these include options for extensions for additional periods. Future revenues
from these contracts can be affected by periodic reopeners that adjust sales
prices based on prevailing market conditions. It is anticipated that these
contracts will require approximately 85 percent of planned production from
Black Thunder and Coal Creek in 1994. Approximately 80 percent of planned 1994
production in Australia is committed under both long and short-term contract
arrangements.
 
  In total, ARCO Coal shipped 47.7 million tons of coal during 1993 and had
1,510 million tons of recoverable coal reserves as of December 31, 1993.
Reference is made to Supplemental Information, Coal Operations on page 57 for
further information concerning reserves and shipments of coal.

REFINING AND MARKETING
 
  ARCO Products operates two domestic petroleum refineries on the West Coast,
the Los Angeles Refinery in Carson, California and the Cherry Point Refinery
near Ferndale, Washington. Both of these refineries are accessible to major
supply sources and major markets through ocean-going tankers, pipelines and
other transportation facilities. Both currently utilize Alaskan North Slope
crude oil exclusively.

  ARCO Products obtains additional gasoline supplies from the Avon, California
refinery of Tosco under a 1986 supply agreement. Pursuant to the agreement,
which has an initial term of 10 years, ARCO Products delivers approximately
50,000 barrels per day of Alaskan North Slope crude oil to Tosco's refinery in
exchange for a quantity of gasoline that is a variable percentage of the
amount of crude oil delivered, based on the price of certain crude oils.
 
  In connection with its refining operations, ARCO Products also produces
petroleum coke and operates electric cogeneration facilities. Petroleum coke,
a refinery by-product, is processed at the company's calciner operations into
calcined coke. ARCO Products operates the Watson Cogeneration Facility at its
Los Angeles Refinery under a joint venture agreement with a subsidiary of
SCEcorp. A second cogeneration facility is located at the calciner operation
in Wilmington, California, near the Los Angeles Refinery.
 
  ARCO Products markets gasoline and other refined petroleum products to both
consumers and resellers. Gasoline is marketed under the ARCO(Registered) 
trademark through independent dealers and distributors and directly to motorists
at branded retail outlets located in Arizona, California, Nevada, Oregon and
Washington. ARCO Products also sells gasoline to unbranded resellers. NGLs are
sold directly to end-use customers and the Watson Cogeneration Facility, and are
also marketed through
 
                                       9
<PAGE>
 
distributors. Jet fuels are sold directly to airlines and the United States
Department of Defense. Calcined coke is sold to domestic and international
industrial consumers. Cargo and bulk sales of petroleum products are also made
to commercial and industrial consumers, and certain products are marketed
through other channels.
 
  As of December 31, 1993, there were 1,611 branded retail outlets, which
included franchisee and Company-operated am/pm(Registered) convenience stores 
and SMOGPROS(Registered) Service Centers, and traditional service stations.
 
  In response to anticipated federal, state and local air quality
requirements, ARCO Products began development of reformulated gasolines in the
late 1980s. In September 1989, ARCO Products introduced its first
reformulated, emission control gasoline, EC-1(Registered) Regular, in Southern
California to replace its regular leaded gasoline. In September 1990, ARCO
Products introduced a second reformulated gasoline, EC-Premium(Registered), 
to replace its super unleaded gasoline in Southern California markets. As of
January 1, 1992, the sale of leaded gasoline was banned in California. ARCO
Products now markets only unleaded and reformulated unleaded gasolines in
California.
 
  EC-1(Registered) Regular, EC-Premium(Registered) and other reformulated 
gasolines being developed by the Company use oxygenates, such as methyl tertiary
butyl ether ("MTBE"), to produce a cleaner burning fuel. ARCO Products has a
small MTBE production unit at the Los Angeles Refinery. In addition, during
1991, ARCO Products and ARCO Chemical entered into long-term sales agreements
providing for delivery of fixed quantities of MTBE to ARCO Products at contract
prices. Also in response to federal and state air quality requirements, ARCO
Products introduced California Air Resources Board ("CARB") specification diesel
into the California market and Environmental Protection Agency ("EPA")
specification diesel into the balance of its U.S. markets in September 1993.
 
  In order to remain in compliance with federal, state and local air quality
requirements that are being phased in over the next several years, ARCO
Products is making major modifications at its Los Angeles Refinery.
 
  Total domestic and foreign refined petroleum product sales, which include
insignificant sales to ARCO Chemical and Lyondell, for the periods indicated,

TRANSPORTATION
 
  ARCO Transportation, through various wholly owned subsidiaries of ARCO,
manages facilities that transport and store petroleum liquids, refined
petroleum products, petrochemicals and natural gas. Ownership interests in
petroleum liquids pipeline systems in the United States include approximately
1,200 miles of gathering lines serving producing fields in California,
Colorado, New Mexico, Oklahoma, Texas and Utah, and approximately 5,300 miles
of common carrier trunk lines extending from producing areas, including
Alaska, to refineries and terminals. Ownership interests in refined petroleum
product and petrochemical pipeline systems in the United States include
approximately 1,900 miles of trunk lines originating at refineries in Texas,
California and Oklahoma; these pipelines move petroleum liquids and refined
petroleum products for all shippers (including ARCO) that properly tender
these materials for transportation. In addition, the Company has interests in
several other petroleum liquids and refined petroleum product pipelines and
several small natural gas pipeline systems in the western United States.
 
  ARCO Transportation Alaska, Inc. ("ATA"), a wholly owned subsidiary of ARCO,
owns an undivided interest in TAPS. TAPS consists of an 800-mile, 48-inch
diameter pipeline system used to transport petroleum liquids from the North
Slope of Alaska to the ice-free port of Valdez in southern Alaska. The
percentage of ownership varies by facility, with ATA's weighted average TAPS
ownership being approximately 21.3 percent. In addition, ATA owns
approximately 21.3 percent of the stock of Alyeska Pipeline Service Company,
which was established to design, construct, operate and maintain TAPS for the
owners. See page 17 of "Environmental Matters--Material Environmental
Litigation." ATA's undivided interest in TAPS is proportionally consolidated
for financial reporting purposes. TAPS 1993 throughput averaged approximately
1,620,000 barrels per day. During 1993, a federal audit team completed a study
that pointed to deficiencies in TAPS operations and maintenance, inspection
procedures, and management. During Congressional hearings following this
audit, the Company reiterated its overriding commitment to safety and high
environmental standards for TAPS.
 
  Kuparuk Pipeline Company, a wholly owned subsidiary of ARCO, owns a 57
percent partnership interest in a pipeline system that links the Kuparuk River
field to TAPS Pump Station No. 1. An average of 333,000 barrels of petroleum
liquids per day was transported through this pipeline system in 1993.
 
  In the Lower 48, ARCO Pipe Line Company, Four Corners Pipe Line Company, and
ARCO Terminal Services Corporation, wholly owned subsidiaries of ARCO, provide
transportation and storage facilities for various types of crude oil, finished
products and petrochemicals. ARCO Pipe Line Company owns and operates
petroleum liquids, product and petrochemical pipelines located east of the
Rocky Mountains; gross throughput of these pipelines averaged 1,117,000
barrels per day in 1993. Four Corners Pipe Line Company owns and operates
common carrier pipelines in the western United States that transported
approximately 279,000 barrels per day of crude oil in 1993. ARCO Terminal
Services Corporation owns and operates pipelines and owns or leases and
operates terminals that provide a variety of storage and transportation
services both to ARCO and third-party customers. In February 1994, in an
effort to strengthen the competitive position and improve efficiencies, the
management of ARCO Pipe Line and Four Corners Pipe Line companies have been
combined.
 
  During 1993, ARCO Transportation completed two significant pipeline
expansions. Line 90, a major west-to-east crude oil pipeline, was expanded to
accommodate 12,000 additional barrels of crude oil per day for a total of up
to 84,000 barrels per day. Additionally, a new long-term agreement for the
shipping of Alaska North Slope crude oil from Long Beach eastward on this
pipeline was signed. Also expanded was the Gulf Coast to Cushing crude oil
pipeline system, that links the Gulf of Mexico port at Texas City with
Midcontinent and Midwest refineries through Cushing, Oklahoma. This project
raised system capacity by up to 40,000 barrels per day, depending on the
viscosity of the crude oil being carried, and is intended to capitalize on
growing demand from domestic refiners for imported crude oil.
 
  ARCO Marine, Inc., a wholly owned subsidiary of ARCO, owns or operates under
long-term lease 10 ocean-going, United States flag tankers with an aggregate
tonnage of approximately 1.5 million tons.

INTERMEDIATE CHEMICALS AND SPECIALTY PRODUCTS
 
  The Company's Intermediate Chemicals and Specialty Products operation
consists of the businesses owned by ARCO Chemical. ARCO currently owns
80,000,001 shares of common stock of ARCO Chemical, which represent 83.3
percent of the outstanding shares.
 
  ARCO Chemical is a leading international manufacturer and marketer of
intermediate chemicals and specialty products used in a broad range of
consumer goods. Major products include propylene oxide ("PO") and its
derivatives (which include polyols and propylene glycols ("PG")), tertiary
butyl alcohol ("TBA") and its derivatives (which include MTBE and ethyl
tertiary butyl ether ("ETBE")), and styrene monomer ("SM") and its derivatives
(including polystyrenics).
 
  ARCO Chemical's principal chemical facilities are located in: Bayport, Texas
(PO, TBA and various derivatives including PG); Channelview, Texas (PO, SM and
various derivatives including polyols and MTBE); Monaca (Beaver Valley),
Pennsylvania (SM derivatives); Rotterdam, the Netherlands (PO, TBA and various
derivatives including PG and MTBE); Fos-sur-Mer, France (PO, TBA and various
derivatives including PG, polyols and MTBE); and a joint venture in Chiba,
Japan (PO and SM). Other production facilities include facilities for the
production of polystyrenics at Painesville, Ohio and polyols at: Institute and
South Charleston, West Virginia; Rieme, Belgium; Kaohsiung, Taiwan; and Anyer,
West Java, Indonesia. ARCO Chemical owns a majority equity interest in the
second PO/SM plant at Channelview, Texas, completed in 1992. The two equity
investors in the plant, which are limited partners, each will take a
substantial portion of the SM output of the plant through long-term processing
agreements.
 
  The following table shows ARCO Chemical's worldwide production capacity (in
millions of pounds per year, except where otherwise noted) for PO, TBA, SM and

  In addition to sales to, or processing agreements with, unrelated third
parties, ARCO Chemical has agreements with the Company and Lyondell which
provide for, among other things, the purchase, sale and processing of various
products and feedstocks. ARCO Chemical sells MTBE at contract prices to ARCO
Products for use in the production of the Company's reformulated gasolines.
During 1991, ARCO Products and ARCO Chemical entered into long-term sales
agreements providing for delivery of fixed quantities of MTBE. Lyondell
provides to ARCO Chemical a portion of the feedstocks purchased by ARCO
Chemical for use at its chemical manufacturing facilities in Texas. Lyondell
also provides certain plant services at these facilities. ARCO Chemical in
turn provides certain feedstocks and supplies to Lyondell. ARCO Chemical is
also a party to certain service agreements and other arrangements with the
Company and Lyondell.
 
  For additional information about ARCO Chemical, a copy of ARCO Chemical's
1993 Annual Report to Stockholders and 1993 Annual Report on Form 10-K can be
obtained by writing to Manager, Investor Relations, ARCO Chemical Company,

Chemical's telephone number is (610) 359-2000.
 
                          EQUITY INTEREST IN LYONDELL
 
  ARCO owns a 49.9 percent equity interest in Lyondell, which is accounted for
on the equity method. Prior to 1989, Lyondell was a wholly owned subsidiary of
ARCO. See Note 20 of Notes to Consolidated Financial Statements on page 52,
and "Management's Discussion and Analysis of Financial Condition and Results
of Operations."
 
  Lyondell is a petrochemical and petroleum processor and marketer. Lyondell
manufactures a wide variety of petrochemicals, including olefins (ethylene,
propylene, butadiene, butylenes and specialty products), polyolefins
(polyethylene and polypropylene), methanol and MTBE, and refined petroleum
products, including gasoline, heating oil, jet fuel, aromatics and lubricants.
 
  For the year ended December 31, 1993, Lyondell recorded total revenues of
approximately $263 million from sales to ARCO Chemical. Lyondell also provides
certain plant services at these facilities. ARCO Chemical in turn provides
certain feedstocks and supplies to Lyondell. See "Products--Intermediate
Chemicals and Specialty Products."
 
  Lyondell historically purchased a portion of its crude oil, natural gas and
NGLs requirements from ARCO. Lyondell currently purchases certain of these
requirements from ARCO's Lower 48 business units under short-term contracts
and/or on the spot market at prices based on prevailing market prices. In
addition, Lyondell and ARCO have entered into a services agreement and various
leases, technology transfers and licenses and other arrangements. During 1993,
Lyondell paid ARCO and its consolidated subsidiaries an aggregate of $73
million under these agreements, arrangements and transactions and received an
aggregate of $278 million.
 
  In July 1993, Lyondell and CITGO Petroleum Corporation ("CITGO"), a
subsidiary of Petroleos de Venezuela, S.A. ("PDVSA"), the Venezuelan national
oil company, created a jointly owned Texas limited liability company,
LYONDELL-CITGO Refining Company Ltd. ("LCR"), that owns and operates
Lyondell's refining business. Lyondell contributed its refinery assets
(including the lube oil blending and packaging plant in Birmingport, Alabama)
and refinery working capital to LCR and retained an approximate 95 percent
participation interest in LCR. CITGO initially contributed $50 million to the
operations of LCR and in exchange received an approximate five percent
participation interest in the ongoing operations of LCR. At the end of 1993,
CITGO made an additional $50 million contribution to the ongoing operations of
LCR, and increased its participation interest to approximately ten percent.
LCR is undertaking a major upgrading project at the refinery to enable the
facility to process substantial additional volumes of very heavy crude oil.
Project engineering for the upgrade is currently underway;
 
                                      13
<PAGE>
 
LCR management anticipates the cost over the next four years to be
approximately $800 million. CITGO will contribute a significant portion of the
funding required to complete this upgrade. Upon completion of the upgrade,
CITGO will own a significant minority interest in LCR and CITGO will have an
option to increase its interest to 50 percent that can be exercised under
certain conditions. In addition, in 1993 PDVSA entered into a long-term
contract to supply heavy crude oil to LCR, and CITGO has a long-term
obligation to purchase a substantial portion of the refined products produced
at the refinery.
 
  For additional information about Lyondell, a copy of Lyondell's 1993 Annual
Report to Stockholders and 1993 Annual Report on Form 10-K can be obtained by
writing to Investor Relations, Lyondell Petrochemical Company, One Houston
Center, 1221 McKinney Street, Houston, Texas 77010. Lyondell's telephone
number is (713) 652-7200.
 
                                CAPITAL PROGRAM
 
  The Company's capital expenditures for additions to fixed assets (including
dry hole costs) totaled approximately $2.1 billion in 1993 and are budgeted at
$1.9 billion for 1994. The levels of future capital expenditures may be
affected by business conditions in the industry, particularly possible changes
in prices of and demand for crude oil, natural gas and petroleum products.
Changes in the tax laws, the imposition of and changes in federal and state
clean air and clean fuel requirements, and other changes in environmental
rules and regulations may also affect future capital expenditures.
 
                                    PATENTS
 
  ARCO owns numerous patents, many of which are available for license to the
petroleum industry, and is itself a licensee under certain patents which are
available generally to the industry. The Company's operations are not
dependent upon any particular patent or patents or upon any exclusive patent
rights.
 
                                  COMPETITION
 
  The petroleum industry is competitive in all its phases, including
manufacturing, distribution and marketing of petroleum products and
petrochemicals. Methods of competition for new sources of supply include
finding and developing such sources and competition in bidding for leases
which may contain such sources and the acquisition of producing properties.
Competitive factors in manufacturing, distribution and marketing include
price, methods and reliability of delivery, product quality, new product
development and, with respect to consumer products, advertising and sales
promotion.
 
  Crude oil and natural gas supplies are currently abundant relative to demand
in the worldwide markets for those commodities. Market prices are typically
volatile as a result of uncertainties caused by world events. ARCO's leasehold
position on the North Slope of Alaska and its emphasis on the cost-efficient
exploration and development of petroleum resources and on innovative marketing
strategies make the Company well situated to compete in this environment.
 
  In the refining, marketing and manufacturing segment of the industry,
refining operations that yield a higher proportion of high-margin products and
marketing operations that put a premium on high volume and innovation are of
primary importance. The Company's historic emphasis on efficient refinery
operations and innovative retail marketing makes ARCO a strong competitor in
its wholesale markets and in its West Coast retail market.
 
  The domestic coal industry serves competitive U.S. markets, where specific
transportation arrangements are often a key element in competition because
transportation costs are a significant component of the delivered price of
coal. Almost all of the Company's domestic coal customers are
 
                                      14
<PAGE>
 
electric utilities. The Company's Australian mines are export-oriented,
largely to Japan, and face worldwide competition, primarily from Canadian,
Indonesian, South African, U.S. and other Australian producers.
 
  Key competitive factors in the intermediate chemicals and specialty products
markets include product price, quality, reliability of supply, technical
support, customer service and potential substitute materials. Commodity
chemicals and polymers compete mainly on the basis of price, while specialty
products compete mainly on the basis of product performance.
 
  The Company ranked twenty-second in sales in the most recent Fortune 500
list of industrial companies.
 
                                HUMAN RESOURCES
 
  As of December 31, 1993, ARCO had approximately 25,100 full-time equivalent
employees, of whom approximately 12 percent were represented by collective
bargaining agents.
 
                           RESEARCH AND DEVELOPMENT
 
  ARCO engages in research for new and improved methods, equipment and
products principally at three facilities located at Plano, Texas, Newtown
Square, Pennsylvania and Anaheim, California. Total research and development
expenses were $109 million, $89 million and $119 million in 1993, 1992 and
1991, respectively.
 
                             ENVIRONMENTAL MATTERS
 
 Site Remediation
 
  The Company is subject to federal, state and local environmental laws and
regulations, including the Comprehensive Environmental Response, Compensation
and Liability Act of 1980, as amended ("CERCLA" or "Superfund"), and the
Superfund Amendments and Reauthorization Act of 1986 and the Resource
Conservation Recovery Act of 1976 ("RCRA"), which may require the Company to
remove or mitigate the effects on the environment of the disposal or release
of certain chemical, mineral and petroleum substances at various sites,
including the restoration of natural resources located at these sites and
damages for loss of use and non-use values. The Company is currently
participating in environmental remediation activities at numerous sites under
Superfund and comparable state statutes at sites associated with discontinued
operations, under RCRA and other state and local statutes at certain operating
sites, and pursuant to indemnification agreements at certain former Company
facilities. The Company is currently participating in environmental
assessments and cleanups under these laws at federal Superfund and state-
managed sites, as well as other clean-up sites, including service stations,
refineries, terminals, chemical facilities, third party landfills, former
nuclear processing facilities, and sites associated with discontinued
operations. The Company may in the future be involved in additional
environmental assessments and cleanups, including the restoration of natural
resources and damages for loss of use and non-use values. The ultimate amount
of the future costs associated with such environmental assessments and
cleanups is indeterminable due to such factors as the unknown nature and/or
extent of contaminants at many sites, the unknown timing, extent and method of
the remedial actions which may be required and the determination of the
Company's liability in proportion to other responsible parties. The Company
continues to estimate the amount of these costs in periodically establishing
reserves based on progress made in determining the magnitude of remediation
costs, experience gained from sites on which remediation has been completed,
the timing, extent and method of remedial actions required by the applicable
governmental authorities and an evaluation of the amount of the Company's
liability considered in light of the liability and financial wherewithal of
the
 
                                      15
<PAGE>
 
other responsible parties. As the scope of the Company's obligation becomes
more clearly defined, there may be changes in these estimated costs, which
might result in future charges against the Corporation's earnings.
 
  The Company's environmental remediation accrual of $648 million at December
31, 1993 covers federal Superfund and state-managed sites as well as other
clean-up sites, including service stations, refineries, terminals, chemical
facilities, third-party landfills, former nuclear processing facilities and
sites associated with discontinued operations. The Company has been named a
potentially responsible party ("PRP") for 123 sites. The number of PRP sites
in and of itself does not represent a relevant measure of liability, because
the nature and extent of environmental concerns vary from site to site and the
Company's share of responsibility varies from sole responsibility to very
little responsibility. The Company reviews all of the PRP sites along with
other sites as to which no claims have been asserted, in estimating the amount
of accrual. The Company's future costs for these sites could exceed the amount
accrued by as much as $1 billion.
 
  Approximately half of the reserve relates to sites associated with the
Company's discontinued operations, primarily mining activities in the states
of Montana and Colorado. Another significant component relates to currently
and formerly owned chemical, nuclear processing, and refining and marketing
facilities, and other sites which received wastes from these facilities. The
Company is also the subject of certain material legal proceedings described
below under the caption "Material Environmental Litigation." The remainder
relates to sites with reserves ranging from $1 million to $10 million per
site. No one site represents more than 15 percent of the total reserve.
Substantially all amounts accrued in the reserve are expected to be paid out
over the next five to six years.
 
 Clean Air
 
  The Federal Clean Air Act Amendments of 1990 (the "1990 Clean Air Act
Amendments") and various state and local laws and regulations impose certain
air quality requirements that may have a significant economic impact on ARCO
during the next decade. Among other things, the 1990 Clean Air Act Amendments
effectively require the manufacture and sale of reformulated and oxygenated
gasolines in areas not meeting specified air quality standards. These
requirements are to be effective by January 1, 1995 for the nine U.S. cities,
including Los Angeles and San Diego, with the worst ozone pollution. In
November 1991, the CARB announced its specifications for reformulated gasoline
effective March 1, 1996, which are stricter than those to be applied under the
federal rules. To comply with these air quality requirements, ARCO expects to
make major modifications at its Los Angeles Refinery. The Company does not
anticipate any material adverse effect upon its consolidated financial
position as a result of compliance with such environmental laws and
regulations.
 
  In 1992 the South Coast Air Quality Management District, or AQMD, which sets
environmental standards for a five county area of Southern California,
proposed a Regional Clean Air Incentives Market ("RECLAIM") program for the
buying and selling of emission credits. On October 15, 1993, after several
modifications, AQMD adopted the program, which includes the innovative credits
trading feature, and emission reductions, pursuant to which the Los Angeles
Refinery must, by 2003, achieve overall reductions from 1992 levels of oxides
of nitrogen (NOx) by 63 percent and oxides of sulfur (SOx) by 83 percent.
 
 Environment-Related Expenditures
 
  For the past three years, the Company's environment-related expenditures
have been comprised of both capital expenditures and operating expenses.
Environment-related capital expenditures include the cost of projects to
reduce and/or eliminate pollution and contamination in the future and the cost
of modifications to the Company's manufacturing facilities necessary to comply
with the aforementioned federal, state and local air quality laws and
regulations. Environment-related operating costs include
 
                                      16
<PAGE>
 
both costs to eliminate, control or dispose of, pollutants, as well as costs
to remediate previously contaminated sites. Sites are remediated using a
variety of techniques, including on site stabilization, bioremediation, soil
removal, pump and treat and other methods as deemed appropriate for each
specific site.
 
  For the past three years, the Company's environment-related capital
expenditures have averaged approximately $280 million per year. The Company
anticipates environment-related capital programs of approximately $440 million
and $360 million for 1994 and 1995, respectively. For the past three years,
the Company's operating expenses for the remediation of previously
contaminated properties either compelled or likely to be compelled in the
foreseeable future by government or third parties have averaged approximately
$160 million per year. Cash payments for site remediation have averaged $191
million per year over the same period. The Company's operating expenses also
include ongoing costs of controlling or disposing of pollutants. For the past
three years, the Company estimates that its operating expenses related to
these ongoing costs have averaged approximately $270 million per year.
 
  In addition to the reserve accrual for environmental remediation costs, the
Company has also accrued, as of December 31, 1993, $788 million for the
estimated cost, net of salvage value, of dismantling facilities as required by
contract, regulation or law, and the estimated costs of restoration and
reclamation of land associated with such facilities.
 
 Material Environmental Litigation
 
  Pursuant to the authority provided under Superfund, the State of Montana has
asserted claims against ARCO for compensation for damage to natural resources up
to the maximum amount allowed by 42 United States Code Section 9607. These
alleged damages, arising out of ARCO's or its predecessors' alleged activities,
include restoration and compensable damages, assessment costs, and prejudgment
interest. These claims, which relate to the four Upper Clark Fork River Basin
Superfund sites in Montana, have been filed both as a lawsuit and an informal
letter claim against the Company. The lawsuit, styled Montana v. ARCO, ex rel.,
was filed on December 12, 1983, in the United States District Court for the
District of Montana (Case No. CV-83-317-HLN-PGH). On August 24, 1984, by
agreement of the parties, the Court temporarily stayed all further proceedings
pending completion of a natural resources damage assessment by the State of
Montana. On August 17, 1990, the Court issued a Case Management Order and lifted
the stay; the litigation proceeded under the order until December 1992, when the
Court issued another temporary stay in an attempt to facilitate settlement
negotiations between the parties. On March 17, 1993, the parties filed a joint
petition seeking an extension of the stay until September 15, 1994 to allow the
parties to engage in settlement negotiations pursuant to a memorandum of
understanding signed by the parties on March 16, 1993. On March 22, 1993, the
Court granted the parties' joint petition.
 
  In addition, on June 23, 1989, the EPA filed a CERCLA cost-recovery action
against ARCO (amended October 15, 1992), styled U.S. v. ARCO, et al. (Case No.
CV-89-039-BU-PGH), in the United States District Court for the District of
Montana, for oversight costs at several of the Upper Clark Fork River Basin
Superfund sites. A stay previously entered in U.S. v. ARCO has been lifted as
of February 15, 1993, and litigation is proceeding on both the EPA's claims
(in the approximate amount of $80 million) and ARCO's counterclaims against
various federal agencies. (In the counterclaims, ARCO seeks contributions from
the federal agencies for remediation costs and for any natural resource damage
liability ARCO might incur in Montana v. ARCO.)
 
  In addition, the State of Colorado has filed a natural resource damage claim
which relates to the Rico-Argentine Mine Site. This claim was originally filed
against the Superfund itself as an administrative claim with the EPA; it has
been denied by the EPA. An additional informal letter claim was filed against
the Company; this claim remains unresolved.

  ARCO and its subsidiary, Atlantic Richfield Hanford Company ("ARHCO"), and
several other companies who have served as government contractors at the
Hanford Nuclear Reservation in south central Washington State (the
"Reservation") are named as defendants in a consolidated complaint in the
United States District Court for the Eastern District of Washington.
Presently, this action is proceeding on the basis of a consolidated complaint
filed on April 19, 1991 (the "Consolidated Complaint") which is titled In re
Hanford Nuclear Reservation Litigation (CY-91-3015-AAM). The Consolidated
Complaint is brought on behalf of over 2,500 individuals and five purported
classes of persons. The Consolidated Complaint alleges that the defendant
government contractors accidentally or deliberately released radioactive and
non-radioactive toxic and hazardous substances generated at the Reservation
into the surrounding air, water and ground. The Consolidated Complaint
contains claims for relief based upon state tort and real estate law and
purportedly arising under the Price-Anderson Act. The Consolidated Complaint
also contains claims for relief purportedly arising under CERCLA. The
Consolidated Complaint seeks extensive relief on behalf of the individual and
class plaintiffs, including compensatory and punitive damages for personal
injury, wrongful death and economic loss, and as well as broad injunctive and
declaratory relief pursuant to CERCLA. The Consolidated Complaint also seeks
attorneys' fees and costs. On October 18, 1991, the District Court dismissed
plaintiffs' claims for abatement, medical monitoring, response costs, and
disclosure of information pursuant to CERCLA. The Court also dismissed
plaintiffs' claims for punitive damages and dismissed one of the purported
classes, the Hanford Downwinders Coalition, from the litigation. The Court
denied defendants' motions for a more definite statement and for dismissal of
certain of plaintiffs' state law claims. On approximately January 6, 1992,
ARCO and ARHCO filed an answer denying the remaining claims of the
Consolidated Complaint. Discovery is proceeding, and no trial date has been
set. On July 9, 1993, a new action, entitled Pamela Durfey, et al. v. E. I. Du
Pont De Nemours and Company, et al. (93-2-01325-5), was filed in the Superior
Court of the State of Washington for the County of Yakima. The complaint,
which names ARCO and ARHCO as defendants, was filed on behalf of a purported
class that includes all people who have lived from 1942 to the present in the
Washington and Oregon counties surrounding the Reservation. This action seeks
"a comprehensive medical monitoring program to permit the early
identification, detection and diagnosis" of diseases caused by the released
radioactive and non-radioactive waste from the Reservation. This complaint has
been removed to the United States District Court for the Eastern District of
Washington. Plaintiffs have filed a motion for remand which is presently
before the Court. With respect to all of these actions, the Company and ARHCO
believe that, should either or both ultimately be held liable, they will be
entitled to indemnification by the federal government as provided under the
Price-Anderson Act, and pursuant to the terms of the contract between ARHCO
and the Atomic Energy Commission. Without confirming or denying the
government's indemnity obligations, the DOE has instructed the defendants to
proceed with the good faith defense of the lawsuits.
 
  ARCO is one of the named defendants in several lawsuits filed in federal
court in Texas brought by approximately 2,500 plaintiffs relating to the
French Ltd. and Sikes (Texas) Superfund sites and several lawsuits filed in
state court in Texas brought by several hundred plaintiffs relating to the
Brio (Texas) Superfund site. These suits generally allege personal injury
and/or property damage caused by chemical substances allegedly sent to the
sites by the Company and other defendants. Most of the claims of the
plaintiffs in the French Ltd. lawsuits have been resolved either by dismissal
or by settlement with plaintiffs. In June 1992, ARCO agreed to settle the
claims of approximately 1,500 plaintiffs relating to the Brio site. Since that
date, new claims have been filed by approximately 1,200 plaintiffs. Neither
the French Ltd. settlements nor the Brio settlement involved amounts which are
material to the Company.
 
  On March 24, 1989, an oil tanker, the EXXON VALDEZ, ran aground near Bligh
Island, Alaska, after taking on crude oil from the Valdez Marine Terminal
operated by Alyeska, of which ATA owns approximately 21 percent. Roughly
240,000 barrels of crude oil were discharged into the waters of Prince William
Sound. As a result, numerous lawsuits seeking compensatory and punitive
damages and injunctions were filed in state and federal courts in Alaska
against Exxon, Alyeska, and Alyeska's
 
                                      18
<PAGE>
 
owner companies (including ATA) alleging, among other things, that Alyeska
responded inadequately to the oil spill. The State of Alaska filed an action
that sought, among other things, the imposition of civil penalties and the
recovery of environmental, economic and punitive damages suffered by the
State. The United States filed an action that sought, among other things, the
recovery of cleanup response costs and environmental damages resulting from
the oil spill. Private plaintiffs filed other actions, many seeking
certification as class actions. On October 8, 1991, the United States District
Court in Alaska approved an Agreement and Consent Decree by which Exxon will
pay $900 million over the next 10 years (with a possible additional $100
million to be paid under a re-opener provision) in settlement of all federal
and state civil damage claims. In further consideration of the Exxon payments
under the Agreement and Consent Decree, Alyeska and its owner companies are
released from federal and state natural resource civil damage claims. On
November 25, 1992, the United States District Court in Alaska approved an
Agreement and Consent Decree by which Alyeska and its owner companies will pay
$2 million to the United States and a total of $29.7 million by February 4,
1995 to the State of Alaska, of which $9.9 million was ATA's share, in
settlement of remaining civil damage claims by federal and state governments.
On July 13, 1993, it was announced that Alyeska and its owner companies had
agreed to pay $98 million in settlement of the lawsuits by all but a handful
of private plaintiffs, of which $20.9 million was ATA's share. This settlement
was made contingent on, among other things, approval by the federal and state
courts. In response to this announced settlement, Exxon Shipping Company filed
a lawsuit against Alyeska and its non-Exxon owner companies in the United
States District Court in Alaska seeking an injunction and stay of certain
aspects of the settlement pending arbitration. Exxon Shipping's principal
contention was that those aspects of the proposed settlement that affect the
claims that Exxon Shipping may have against Alyeska and its owner companies as
a result of the spill must be arbitrated because such claims fall under the
arbitration provisions of the agreement that governed the calling of vessels
at the Valdez Marine Terminal at the time of the spill. At the October 28,
1993 approval hearing on the settlement, the settlement was tentatively
approved as fair, reasonable and adequate. On December 8, 1993, the United
States District Court in Alaska issued various orders generally resolving the
issues raised by Exxon Shipping concerning the settlement in favor of Alyeska
and its owner companies. Exxon Shipping has sought reconsideration of one of
those judicial orders, appealed two others and may appeal the rest of the
orders.
 
  On November 21, 1990, ARCO filed a complaint in Los Angeles County Superior
Court, Atlantic Richfield Company v. AETNA Casualty and Surety Company of
America, et al. (Case No. BC 015575), naming more than 70 insurance companies
as defendants and seeking recovery under numerous insurance policies in effect
at times during past years for certain environmental expenses incurred by
ARCO. The claims arise from the activities of ARCO and its predecessor
companies, including Anaconda, at sites and locations throughout the United
States. The Company cannot predict the outcome of this litigation, which may
be protracted.
 
 Conclusion
 
  Environmental concerns, including the minimization and prevention of
environmental contamination from ongoing operations, and the cost-effective
remediations of existing contaminated sites, continue to be vital factors in
the Company's future planning. See Note 12 of Notes to Consolidated Financial
Statements on page 47, and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

ITEM 3. LEGAL PROCEEDINGS
 
THE COMPANY
 
  On March 23, 1979, in the case of Van Vranken, et al. v. Atlantic Richfield,
two California service station dealers purporting to represent a class of all
resellers of gasoline, aviation fuels, butane and propane sued the Company in
the United States District Court for the Northern District of California (Case
No. C-79-0627-SW) for allegedly willfully violating the Department of Energy's
("DOE") 1973-1981 price regulations by unlawfully inflating its costs of crude
oil eligible for recovery. On March 25, 1986, the District Court certified the
plaintiffs as representatives of the class for purchases made between May 1,
1976 and January 28, 1981. On July 23, 1992, a jury found for the Company on
the class' original claim, and for the class on three subsequent claims in the
amount of $22.8 million, plus prejudgment interest. On October 22, 1992, the
trial court ordered a formula for interest resulting in a total judgment of
approximately $63 million. On September 30, 1993, the United States Court of
Appeals for the Federal Circuit affirmed, without opinion, the trial court's
judgment. The Company has sought reconsideration.
 
  On June 7, 1989, the City of New York, the New York City Housing Authority
and the New York City Health and Hospitals Corporation brought suit in the
Supreme Court of the State of New York for the County of New York (Case No.
14365/89) against six alleged former lead pigment manufacturers or their
successors (including ARCO as successor to International Smelting and Refining
Company ("IS&R"), a former subsidiary of The Anaconda Company), and the Lead
Industries Association ("LIA"), a trade association. Plaintiffs seek to
recover damages in excess of $50 million including (i) past and future costs
of abating lead-based paint from housing owned by New York City and the New
York City Housing Authority; (ii) other costs associated with dealing with the
presence of lead-based paint in that housing and privately owned housing; and
(iii) any amounts paid by the City or the Housing Authority to tenants because
of injuries caused by the ingestion of lead-based paint. Plaintiffs also seek
punitive damages and attorney fees. On January 7, 1991, defendant Eagle-
Picher, one of the lead pigment manufacturers, filed for Chapter 11 bankruptcy
protection in the Southern District of Ohio, for reasons unrelated to this
litigation. As a result of the filing, all proceedings against Eagle-Picher
have been stayed in this litigation. On December 23, 1991, the Court dismissed
plaintiffs' claims of negligent product design, negligent failure to warn, and
strict liability as time-barred under the applicable statute of limitation.
The Court also ruled, however, that the plaintiffs' fraud and restitution
claims were adequately pled and that more facts were needed to determine if
the fraud claim was also time-barred. Interlocutory appeals were taken, and
this decision was affirmed. On March 12, 1992, ARCO filed its answer to the
complaint and its counterclaims against the City of New York and the New York
City Housing Authority. On April 8, 1993, pursuant to stipulation by the
parties, the trial court entered an order dismissing with prejudice
plaintiffs' claims for indemnification arising from third-party personal
injury claims resolved before March 15, 1993, and dismissing without prejudice
claims for indemnification brought after that date. On September 3, 1993,
plaintiffs filed an amended complaint adding American Cyanamid Company and
Fuller-O'Brien Corporation as defendants.
 
  On August 25, 1992, ARCO (as successor to IS&R) was added as a defendant to
a purported class action suit pending in the Court of Common Pleas in Cuyahoga
County (Cleveland), Ohio, Jackson, et al. v. The Glidden Company, et al. (Case
No. 236835), that seeks on behalf of the three named plaintiffs, and all other
persons similarly situated in the state of Ohio, money damages for injuries
allegedly suffered from exposure to lead paint, punitive damages, and an order
requiring defendants to remove and abate all lead paint applied to any
building in Ohio. The suit names as defendants, in addition to ARCO, the LIA
and 16 companies alleged to have participated in the manufacture and sale of
lead pigments and paints and includes causes of action for strict product
liability, negligence, breach of warranty, fraud, nuisance, restitution,
negligent infliction of emotional distress, and enterprise, market share and
alternative liability. On July 29, 1993, the Court entered an order granting
defendants' motion to dismiss the complaint on the grounds that Ohio law does
not recognize market share,
 
                                      20
<PAGE>
 
enterprise or alternative liability causes of action in this case. On August
27, 1993, plaintiffs filed their notice of appeal.
 
  In addition, the Company is a defendant in several lawsuits, brought by
individuals that allege injury from exposure to lead paint. These cases, in
the aggregate, are not material to the financial condition of the Company.
 
  On July 5, 1990, an explosion and fire occurred at ARCO Chemical's
Channelview, Texas plant. The incident resulted in the death of 17 people and
in significant damage to the waste water treatment section of the plant, with
some damage to the adjacent area providing utilities to the plant. Various
lawsuits have been filed and claims made against ARCO Chemical for wrongful
death, personal injury and property damage in connection with this incident,
most of which have been resolved.
 
ENVIRONMENTAL PROCEEDINGS
 
  As discussed under the caption "Environmental Matters," ARCO is currently
participating in environmental assessments and cleanups at numerous operating
and non-operating sites under Superfund and comparable state laws, RCRA and
other state and local laws and regulations, and pursuant to third party
indemnification requests, and is the subject of material legal proceedings
relating to certain of these sites. See "Environmental Matters--Material
Environmental Litigation." Set forth below is a description, in accordance
with SEC rules, of certain fines and penalties imposed by governmental
agencies in respect of environmental rules and regulations.
 
  In September 1991, the California Department of Toxic Substances Control
filed an administrative complaint against ARCO Products Company seeking a
civil penalty of $137,500 for failure to comply with certain hazardous waste
regulations. The alleged violations stem from sandblasting and related actions
by subcontractors while performing work at the Los Angeles Refinery. In
December 1991, an administrative law hearing was held on these alleged
violations. The Administrative Law Judge proposed a reduced penalty of
$62,000, and the matter has been settled on that basis.
 
  ARCO Chemical has discovered that certain organic waste material is situated
in the soil and ground water at portions of its Monaca, Pennsylvania (Beaver
Valley) plant. ARCO Chemical has commenced a feasibility study to determine
the technology required to remedy the conditions at the plant. Concurrently,
ARCO Chemical is working with the Pennsylvania Department of Environmental
Resources ("DER") to design a plan to remedy the conditions at the plant. ARCO
Chemical has signed an agreement with Beazer East, Inc., the successor to
Koppers Inc. (the previous owner of the Beaver Valley plant), whereby Beazer
East, Inc. has agreed to pay for approximately 50 percent of the cost of the
remediation. ARCO Chemical has agreed to pay to the Pennsylvania DER a fine in
the amount of $300,000 in settlement for contamination of the ground water at
the plant.
 
  In August 1993, the City Prosecuting Attorney of Long Beach, California,
filed a complaint against ARCO Terminal Services Corporation ("ATSC"), an ARCO
subsidiary, alleging that ATSC illegally disposed of hazardous waste. A second
complaint was filed against ATSC and Four Corners Pipe Line Company ("FCPL"),
another ARCO subsidiary, alleging that ATSC and FCPL illegally disposed of
hazardous waste. The allegations made in each complaint are not related. In
December 1993, pursuant to the provisions of judicially approved Orders for
Civil Compromise, the complaints were dismissed. Liability was not admitted
with regard to any of the allegations raised in the complaints, but payments
in the amount of $150,000 and $100,000 have been placed into escrow accounts
to fund environmental training and the acquisition of various materials and
equipment to be used for environmental purposes.
 
  In addition to the matters reported herein, from time to time, certain of
the Company's operating divisions and subsidiaries receive notices from
federal, state or local governmental entities of alleged violations of
environmental laws and regulations pertaining to, among other things, the
disposal, emission and storage of chemical and petroleum substances, including
hazardous wastes. Such alleged violations may become the subject of
enforcement actions or other legal proceedings and may involve monetary
sanctions of $100,000 or more (exclusive of interest and costs).
 
                                      21
<PAGE>
 
OTHER LITIGATION
 
  The Company and its subsidiaries are defendants in numerous suits in which
they are not covered by insurance which involve smaller amounts than the
matters described above. Although the legal responsibility and financial
impact in respect to such litigation cannot be ascertained, it is not
anticipated that these suits will result in the payment by the Company or its
subsidiaries of monetary damages which in the aggregate would be material in
relation to the net assets of the Company and its subsidiaries.
 
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 1993.

  New Class of Preferred Stock. Under the Certificate of Incorporation, as
amended following approval by stockholders on May 3, 1993, the Board is
authorized to issue, at any time or from time to time, one or more series of
Preferred Stock at its discretion. In addition, the Board has the power to
determine all designations, powers, preferences and the rights of such stock
and any qualifications, limitations and restrictions, including but not
limited to: (i) the designation of series and numbers of shares; (ii) the
dividend rights, if any; (iii) the rights upon liquidation or distribution of
the assets of the Company, if any; (iv) the conversion or exchange rights, if
any; (v) the redemption provisions, if any; and (vi) the voting rights, if
any.
 
  So long as the Preference Stocks are outstanding, and only for that period
of time, the rights of the Preferred Stock are subordinate to the rights of
the holders of Preference Stocks.
 
  Dividend Rights. Holders of $3.00 Preference Stock and holders of $2.80
Preference Stock are entitled to receive cumulative dividends at the annual
rate of $3.00 per share and $2.80 per share, respectively, payable quarterly,
before cash dividends are paid on the Preferred Stock, if any, and the Common
Stock. Shares of $3.00 Preference Stock and shares of $2.80 Preference Stock
rank on a parity as to dividends. After provision for payment in full of
cumulative dividends on the outstanding $3.00 Preference and $2.80 Preference
Stocks, and the payment in full of cumulative dividends on the outstanding
Preferred Stock, if any, dividends may be paid on the Common Stock as the
Board of Directors may deem advisable, within the limits and from the sources
permitted by law.
 
 
                                      26

  Conversion Rights. Each share of $3.00 Preference Stock is convertible, at
the option of the holder, into six and eight-tenths (6.8) shares of Common
Stock of the Company at any time, and each share of $2.80 Preference Stock is
convertible, at the option of the holder, into two and four-tenths (2.4)
shares of Common Stock of the Company at any time. These conversion rates are
subject to adjustment as set forth in the Certificate of Incorporation. Shares
of Preferred Stock would be convertible, if at all, on such terms as were
designated by the Board of Directors.
 
  Voting Rights. The holders of $3.00 Preference Stock are entitled to eight
votes per share; holders of $2.80 Preference Stock are entitled to two votes
per share; and holders of Common Stock are entitled to one vote per share.
Holders of $3.00 Preference and $2.80 Preference Stocks are entitled to vote
cumulatively for directors; holders of Common Stock have no cumulative voting
rights. The $3.00 Preference, $2.80 Preference and Common Stocks vote together
as one class, except as provided by law and except as to certain matters which
require a vote by the holders of $3.00 Preference Stock or by the holders of
$2.80 Preference Stock as a separate class as set forth below.
 
  The Certificate of Incorporation provides that if the Company shall be in
default with respect to dividends on the $3.00 Preference Stock in an amount
equal to six quarterly dividends, the number of directors of the Company shall
be increased by two at the first annual meeting thereafter, and at such
meeting and at each subsequent annual meeting until all dividends on the $3.00
Preference Stock shall have been paid in full, the holders of the $3.00
Preference Stock shall have the right, voting as a class, to elect such two
additional directors. The Certificate of Incorporation contains identical
provisions with respect to the $2.80 Preference Stock.
 
  The Certificate of Incorporation provides that the Company shall not,
without the assent of the holders of two-thirds of the then outstanding shares
of $3.00 Preference Stock, (a) change any of the terms of the $3.00 Preference
Stock in any material respect adverse to the holders, or (b) authorize any
prior ranking stock; and that the Company shall not, without the assent of the
holders of a majority of the then outstanding shares of $3.00 Preference
Stock, (1) authorize any additional $3.00 Preference Stock or stock on a
parity with it; (2) sell, lease or convey all or substantially all of the
property or business of the Company; or (3) become a party to a merger or
consolidation unless the surviving or resulting corporation will have
immediately after such merger or consolidation no stock either authorized or
outstanding (except such stock of the Company as may have been authorized or
outstanding immediately before such merger or consolidation of such stock of
the surviving or resulting corporation as may be issued upon conversion
thereof or in exchange therefor) ranking as to dividends or assets prior to or
on a parity with the $3.00 Preference Stock or the stock of the surviving or
resulting corporation issued upon conversion thereof or in exchange therefor.
The Certificate of Incorporation contains identical provisions with respect to
the $2.80 Preference Stock.
 
  The holders of Preferred Stock, if any, would have such voting rights, if
any, as were designated by the Board.

provides in general that any direct or indirect purchase by the Company of any
of its voting stock (or rights to acquire voting stock) known to be
beneficially owned by any person or group which holds more than 3 percent of a
class of its voting stock and which has owned the securities being purchased
for less than two years must be approved by the affirmative vote of at least
66 2/3 percent of the votes entitled to be cast by the holders of the voting
stock. Such approval shall not be required with respect to any purchase by the
Company of such securities made (i) at or below fair market value (based on
average New York Stock Exchange closing prices over the preceding 90 days) or
(ii) as part of a Company tender offer or exchange offer made on the same
terms to all holders of such securities and complying with the Securities
Exchange Act of 1934 or (iii) in a Public Transaction (as defined).
 
  Rights to Purchase Common Stock. On May 27, 1986, the Board of Directors of
the Company declared a dividend distribution of one Right for each outstanding
share of Common Stock to the stockholders of record on June 9, 1986 (the
"Record Date"). Each Right entitles the registered holder to purchase from the
Company one share of Common Stock at a price of $200 per share (the "Purchase
Price"), subject to adjustment. The description and terms of the Rights are
set forth in a Rights Agreement (the "Rights Agreement") between the Company
and Morgan Guaranty Trust Company of New York, as Rights Agent (the "Rights
Agent").
 
  The Rights were issued on the Record Date. Thereafter, as long as the Rights
are attached to the Common Stock, the Company will issue one Right with each
share of Common Stock that shall become outstanding so that all such shares
will have attached Rights.
 
  The Rights are attached to all Common Stock certificates representing
outstanding Common Stock, and no separate certificates evidencing Rights
("Right Certificates") have been distributed. Until the earlier to occur of
(i) 10 days following a public announcement that a person or group of
affiliated or associated persons acquired, or obtained the right to acquire,
beneficial ownership of 20 percent or more of the outstanding shares of Common
Stock (an "Acquiring Person") or (ii) 10 days following the earlier of the
commencement of, or the announcement of an intention to make, a tender offer
or exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 30 percent or more of the outstanding shares
of Common Stock (the earlier of such dates described in (i) and (ii) above
being called the "Distribution Date"), the Rights are evidenced by such Common
Stock certificate with a copy of the Summary of Rights attached thereto. The
date of announcement of the existence of an Acquiring Person referred to in
clause (i) above is hereinafter referred to as the "Shares Acquisition Date."
The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with the Common Stock. Until the
Distribution Date (or earlier redemption or expiration of the Rights), Common
Stock certificates issued after the Record Date upon transfer or issuance of
Common Stock contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates evidencing Common
Stock outstanding as of the Record Date, even without a copy of the Summary of
Rights attached thereto, will also constitute the transfer of the Rights
associated with the Common Stock represented by such certificate. As soon as
practicable following the Distribution Date, Right Certificates will be mailed
to holders of record of the Common Stock as of the close of business on the
Distribution Date and such separate Right Certificates alone will evidence the
Rights.
 
  The Rights are not exercisable until the Distribution Date. The Rights will
expire on June 9,1996, unless earlier redeemed by the Company as described
below.
 
                                      28
<PAGE>
 
  The Purchase Price payable, and the number of shares of Common Stock or
other securities or property issuable, upon exercise of the Rights are subject
to adjustment from time to time to prevent dilution (i) in the event of a
stock dividend on, or a subdivision, combination or reclassification of the
Common Stock, (ii) upon the grant to holders of the Common Stock of certain
rights or warrants to subscribe for Common Stock or convertible securities at
less than the current market price of the Common Stock or (iii) upon the
distribution to holders of the Common Stock of evidences of indebtedness or
assets (excluding regular periodic cash dividends out of earnings or retained
earnings at a rate not in excess of 125 percent of the rate of the last cash
dividend theretofore paid or dividends payable in Common Stock) or of
subscription rights or warrants (other than those referred to above).
 
  In the event that the Company were to be acquired in a merger or other
business combination transaction, or more than 50 percent of its assets or
earning power were sold, proper provision would be made so that each holder of
a Right would thereafter have the right to receive, upon the exercise thereof
at the then current exercise price of the Right, that number of shares of
common stock of the acquiring company which at the time of such transaction
would have a market value of two times the exercise price of the Right. In the
event that the Company were to be the surviving corporation in a merger with
an Acquiring Person and its Common Stock were not changed or exchanged, or in
the event that an Acquiring Person were to engage in one of a number of self-
dealing transactions or certain other events occur while there is an Acquiring
Person (e.g., a reverse stock split), as specified in the Rights Agreement,
proper provision would be made so that each holder of a Right (except as
provided below) would thereafter have the right to receive upon exercise that
number of shares of Common Stock of the Company having a market value of two
times the exercise price of the Right. Upon the occurrence of any of the
events described in the preceding sentence, any Rights that are or were at any
time on or after the earlier of (a) the Shares Acquisition Date and (b) the
Distribution Date beneficially owned by an Acquiring Person will immediately
become null and void, and no holder of such Rights will have any right with
regard to such Rights from and after such occurrence.
 
  With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1
percent in such Purchase Price. No fractional shares will be issued and in
lieu thereof, an adjustment in cash will be made based on the market price of
the Common Stock on the last trading date prior to the date of exercise.
 
  At any time prior to the time that a person or group of affiliated or
associated persons has acquired beneficial ownership of 20 percent or more of
the outstanding Common Stock, the Company may redeem the Rights in whole, but
not in part, at a price of $0.10 per Right (the "Redemption Price").
Immediately upon the action of the Board of Directors of the Company electing
to redeem the Rights, the Company will make announcement thereof, and upon
such election, the right to exercise the Rights will terminate and the only
right of the holders of Rights will be to receive the Redemption Price.
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of the Company, including, without limitation, the right to
vote or to receive dividends.
 
  While the distribution of the Rights was not, and the issuance of Rights
thereafter is not, taxable to plan participants or the Company, stockholders
may recognize taxable income if the Rights become exercisable.
 
  The terms of the Rights may be amended by the Board of Directors of the
Company and the Rights Agent, provided that the amendment does not adversely
affect the interests of the holders of Rights.
 
  The Rights have certain antitakeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by its Board of Directors, except pursuant to an offer
conditioned on a substantial number of Rights being acquired. The Rights
should not interfere with any merger or other business combination approved by
the Board of Directors at a time when the Rights are redeemable.
 
  A copy of the Rights Agreement is filed as an exhibit hereto. This summary
description of the Rights is qualified in its entirety by reference thereto.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
OVERVIEW OF 1993 RESULTS

In 1993, ARCO's net income was $269 million, or $1.66 per share. Operating
results were lower compared to 1992. Operations in 1993 benefited from improved
margins and higher gasoline sales volumes in ARCO's West Coast refining and
marketing operations, higher coal sales volumes and higher natural gas prices.
These benefits were more than offset by lower crude oil prices and volumes,
lower natural gas volumes, higher exploration and selling, general and
administrative expenses and lower after-tax earnings from transportation
operations.

The 1993 results included net charges of $545 million after tax related to
reorganization of ARCO's Lower 48 oil and gas operations, the impact of the
federal corporate tax rate increase on deferred taxes, litigation issues,
reserves for future environmental remediation and a loss on the sale of
Brazilian marketing subsidiaries partially offset by gains from Lower 48
property sales.

The charges associated with the fourth quarter reorganization of ARCO's Lower 48
oil and gas operations were $450 million after tax. Included in those charges
were unusual items of $659 million before tax, $404 million after tax, primarily
related to writedowns for sale or other disposition of oil and gas properties
and excess office space, in addition to workforce reductions. The incremental
cash cost associated with these charges is approximately $60 million after tax.

OVERVIEW OF 1992 RESULTS

In 1992, ARCO's net income was $801 million, or $4.96 per share. The improvement
in operating results compared to 1991 reflected improved margins and higher
sales volumes in refining and marketing operations, lower lease operating costs,
higher sales volumes and margins in chemical operations and higher natural gas
prices, partially offset by lower natural gas sales volumes. In addition, income
from equity earnings, interest income and interest expense were lower in 1992.

The 1992 results included approximately $140 million after tax in net benefits
primarily related to unusual items, partially offset by provisions for future
environmental costs. Unusual items were $271 million before tax, $211 million
after tax, and were comprised of a settlement on assets nationalized by Iran and
recognition of a previously deferred portion of the gain from the 1989 sale of a
majority interest in Lyondell Petrochemical Company (Lyondell), partially
offset by a charge related to the withdrawal by ARCO Chemical Company (ARCO
Chemical) from a South Korean joint venture.

The 1992 results also included a net after-tax charge of 

                                      31
<PAGE>
 
$392 million, or $2.43 per share, for the cumulative effect of adopting two new
accounting standards related to non-pension postretirement benefits and income
taxes.

OVERVIEW OF 1991 RESULTS

In 1991, ARCO's net income was $709 million, or $4.39 per share. Results
included net charges for unusual items of $503 million before tax, $312 million
after tax, primarily related to personnel reductions, anticipated loss on
property sales and property writedowns.

RESULTS OF CONSOLIDATED OPERATIONS

REVENUES

Sales and other operating revenues were $18.5 billion in 1993, $18.7 billion in
1992 and $18.2 billion in 1991. The decrease in revenues in 1993, compared to
1992, resulted from lower crude oil prices and volumes, lower natural gas
volumes, decreased crude oil trading volumes and lower refined and chemical
products prices, partially offset by increased natural gas marketing volumes and
higher refined and chemical products sales volumes and natural gas prices.

The increase in revenues in 1992, compared to 1991, resulted from higher crude
oil trading volumes, refined product prices and sales volumes, chemical product
sales volumes and natural gas prices, partially offset by lower crude oil prices
and natural gas volumes.

Income from equity investments was $40 million in 1993, $22 million in 1992 and
$119 million in 1991. The increase in income from equity investments in 1993,
compared to 1992, primarily reflected reduced losses from ARCO Chemical's equity
affiliates. The lower income in 1992, compared to 1991, primarily resulted from
a decline in earnings from Lyondell.

Other revenues were $492 million in 1993, compared to $376 million in 1992 and
$385 million in 1991. The increase in 1993 reflected higher gains on asset
sales.

EXPENSES

Trade purchases were $7.2 billion in 1993, $7.3 billion in 1992 and $7.0 billion
in 1991. The 1993 trade purchases decrease compared to 1992 reflected lower
crude oil trading prices and volumes and lower purchased volumes of finished
refined products and chemical feedstocks, partially offset by higher natural gas
marketing volumes and prices. The trade purchases increase in 1992, compared to
1991, related primarily to higher crude oil trading volumes, partially offset by
lower crude oil prices.

Operating expenses were $3.3 billion in 1993, $3.2 billion in 1992 and $3.1
billion in 1991. In 1993, operating expenses were higher than in 1992 as a
result of litigation-related accruals, higher compensation and contract
personnel costs associated with downstream and coal operations and higher
maintenance costs, including turnarounds at three chemical plants, partially
offset by lower operating costs in oil and gas operations. In 1992, lower
operating costs in oil and gas were offset by higher operating costs in chemical
operations.

Exploration expenses were $667 million in 1993, $567 million in 1992 and $593
million in 1991. The increase in 1993, compared to 1992, reflected higher dry
hole costs in Alaska and increased activity overseas, partially offset by
decreased activity in the Lower 48.

Selling, general and administrative expenses were $1.8 billion in 1993, $1.7
billion in 1992, and $1.8 billion in 1991. Increased expenses in 1993, compared
to 1992, primarily resulted from higher compensation expense and higher delivery
and advertising costs. The decrease in expenses in 1992, compared to 1991,
primarily reflected lower insurance and pension costs.

Taxes other than excise and income taxes were $1.1 billion in 1993, $1.2 billion
in 1992, and $1.1 billion in 1991. The decrease in 1993 primarily resulted from
lower production taxes related to lower crude oil prices and volumes. The
increase in 1992 primarily resulted from an increase in the Brazilian value-
added tax rate.

Excise taxes were $1.3 billion in 1993, $1.2 billion in 1992 and $1.1 billion in
1991. The increase in 1993, compared to 1992, primarily resulted from the fourth
quarter 1993 federal excise tax rate increase, the full-year effect in 1993 of
increased state excise tax rates in 1992 and higher refined products sales
volumes. The increase in 1992, compared to 1991, resulted from higher refined
product sales volumes and increases in state excise tax rates in certain states
in the fourth quarter of 1992.

Depreciation, depletion and amortization was $1.7 billion in 1993, $1.8 billion
in 1992 and $1.7 billion in 1991. The decrease in 1993, compared to 1992,
resulted from

                                     32
<PAGE>

the sale of Lower 48 oil and gas properties, partially offset by a
$73 million accrual for the plugging and abandonment of onshore wells. The
increase in 1992, compared to 1991, included the startup of the new ARCO
Chemical propylene oxide/styrene monomer plant in Channelview, Texas and assets
placed in service at the Corporation's two West Coast refineries.

Interest expense was $715 million in 1993, $762 million in 1992 and $892 million
in 1991. A decline in the weighted average interest rate on outstanding long-
term debt in 1993 and 1992 is the primary cause of the lower interest expense
compared to 1991.

The Corporation's effective tax rate was 51.6% in 1993, compared to 35.6% in
1992 and 36.2% in 1991. The higher effective tax rate in 1993 reflected
increased taxes on foreign income and the effect of the 1993 federal tax rate
increase on deferred taxes.

RESULTS OF SEGMENT OPERATIONS

OIL AND GAS

ARCO's worldwide oil and gas exploration and production operations earned $45
million after tax in 1993, versus $816 million after tax in 1992. The effect of
lower crude oil prices and volumes and natural gas volumes and higher dry hole
expense, partially offset by higher natural gas prices and lower depletion and
lease operating costs, resulted in the lower earnings for 1993. The 1993 results
included net charges of approximately $390 million after tax comprised of the
previously discussed charges associated with the Lower 48 reorganization, the
federal tax rate increase and other charges, partially offset by gains on
property sales. Annual future cost savings associated with the Lower 48
reorganization are estimated to be approximately $100 million after tax. The
1992 results included a net benefit of $138 million after tax consisting of
gains from the Iranian settlement, and gains from Lower 48 property sales,
partially offset by charges associated with the downsizing of Lower 48
operations.

ARCO's oil and gas exploration and production operations earned $816 million
after tax in 1992, up from $549 million after tax in 1991. The 1992 results
reflected the effect of lower operating and exploration costs and higher natural
gas prices, offset by lower natural gas sales volumes, compared to 1991. The
1991 results included approximately $170 million after tax in net charges
related to personnel reductions and the anticipated loss on divestiture of
properties in the Lower 48, partially offset by a benefit from the reduction in
U.K. corporation tax rates.

The Corporation's domestic composite average price for crude oil was $11.67 per
barrel in 1993, $12.92 per barrel in 1992 and $12.93 per barrel in 1991. Average
domestic natural gas prices were $1.93 per thousand cubic feet in 1993, $1.65
per thousand cubic feet in 1992 and $1.54 per thousand cubic feet in 1991.

Worldwide petroleum liquids production averaged 684,400 barrels per day in 1993,
738,200 barrels per day in 1992 and 744,200 barrels per day in 1991. Volumes
decreased in 1993 as a result of Lower 48 property divestitures and natural
field declines, partially offset by increased overseas production. Natural field
decline in Alaska was partially offset by the September 1993 startup of the
first phase of the second gas handling expansion facility (GHX-2) at Prudhoe Bay
and new volumes which came on-stream from the Greater Point McIntyre area in
October 1993. Worldwide production in 1992, compared to 1991, benefited from
increased international volumes, although this was offset by natural field
declines and Lower 48 property divestitures.

ARCO's share of production from its largest Alaskan field, Prudhoe Bay, was
250,800 barrels of petroleum liquids per day in 1993, compared to 270,500
barrels per day in 1992 and 281,700 barrels per day in 1991. The decline in 1993
and 1992, compared to 1991, primarily reflected natural field decline.

ARCO's share of petroleum liquids production from the Kuparuk River field was
151,500 barrels per day in 1993 compared to 150,800 barrels per day in 1992 and
140,300 barrels per day in 1991. The increase in 1992, compared to 1991,
reflected the completion as of July 1, 1992 of a 24-month production payback of
9,000 barrels per day and improved field operations.

Lower 48 petroleum liquids production was 186,000 barrels per day in 1993,
221,600 barrels per day in 1992 and 227,900 barrels per day in 1991. Domestic
natural gas production totaled 911 million cubic feet per day in

                                     33
<PAGE>
 
1993, 1.2 billion cubic feet per day in 1992 and 1.4 billion cubic feet per day
in 1991. The decreases in 1993 and 1992 production were primarily associated
with the sale of Lower 48 properties and natural field declines.

Foreign petroleum liquids production averaged 79,700 barrels per day in 1993,
77,700 barrels per day in 1992 and 75,700 barrels per day in 1991. Foreign
natural gas production increased to 321 million cubic feet per day in 1993 as a
result of the first full year of production from the Pickerill field in the
United Kingdom North Sea and new production from the Orwell and Murdoch fields
in the U.K. North Sea and from the offshore Northwest Java Sea field in
Indonesia, all of which began production in late 1993. The decrease in 1992
natural gas production to 240 million cubic feet per day from 261 million cubic
feet per day in 1991, reflected primarily natural field decline in the United
Kingdom.

COAL

After-tax earnings from coal operations were $107 million in 1993, $83 million
in 1992 and $33 million in 1991. The improvement in 1993 earnings reflected
record sales volumes as a result of strong electric utility demand and reduced
East Coast supply as a result of a mine workers strike. Australian mines also
set production volumes and sales records for 1993. 1993 results included a
benefit of approximately $10 million after tax associated with a change in the
accrued estimated loss on the sale of the Coal Resources of Queensland (CRQ)
mine, which was completed in January 1993. Included in the 1991 earnings were
approximately $50 million in net after-tax charges primarily associated with a
writedown of the CRQ mine, partially offset by gains from the sale of Venezuelan
and other assets. Total worldwide coal shipments in 1993 were 47.7 million tons
compared to 39.8 million tons in 1992 and 41.6 million tons in 1991.

REFINING AND MARKETING

After-tax earnings for refining and marketing operations were $307 million in
1993, $346 million in 1992 and $266 million in 1991. Earnings were lower in
1993, compared to 1992, because operating results were offset by a net charge of
approximately $80 million after tax, comprised primarily of litigation-related
accruals, the loss associated with the sale of the Brazilian marketing
subsidiaries and the effect of the federal tax rate increase on deferred taxes.
The improved earnings in 1992, compared to 1991, were the result of higher
margins and sales volumes in the West Coast marketing area. The 1992 results
included a charge of approximately $40 million after tax primarily for
environmental costs related to previously divested operations. The 1991 earnings
included approximately $10 million of net after-tax charges for personnel
reductions, future environmental remediation primarily associated with
previously divested properties and certain legal exposures, partially offset by
benefits associated with accounting and tax adjustments related to Brazilian
operations.

West Coast petroleum products sales totaled 481,500 barrels per day in 1993,
479,500 barrels per day in 1992 and 466,400 barrels per day in 1991. The higher
level of sales in 1993, compared to 1992, resulted from increased demand. The
higher level of sales in 1992, compared to 1991, resulted from increased market
share. The marketing operations supplemented ARCO's production with third-party
purchases in order to meet increased sales.

TRANSPORTATION

After-tax earnings for the transportation operations were $189 million in 1993,
$239 million in 1992 and $212 million in 1991. The 1993 earnings were lower,
compared to 1992, as a result of a lower Trans Alaska Pipeline System (TAPS)
tariff, lower volumes and the effect of the federal tax rate increase on
deferred taxes. In 1992, improved results from Lower 48 terminal and pipeline
operations offset a decline in earnings from TAPS. The 1991 earnings included
after-tax charges of approximately $30 million for personnel reduction costs and
for settlement of the Kuparuk Pipeline tariff rate litigation.

INTERMEDIATE CHEMICALS AND SPECIALTY PRODUCTS

After-tax earnings for the intermediate chemicals and specialty products segment
were $239 million in 1993, $210 million in 1992 and $192 million in 1991. The
segment consists of ARCO Chemical, an 83.3 percent owned subsidiary of the
Corporation. ARCO Chemical's reported net income in 1993 included a $10 million
after-tax loss on early debt extinguishment and benefited from a lower effective
income tax rate. The 1992
                                     34
<PAGE>

results included $56 million before tax for a charge resulting from ARCO
Chemical's withdrawal from the YUKONG ARCO Chemical Ltd., joint venture in South
Korea.

In 1993, increased sales volumes in ARCO Chemical's core products worldwide were
offset by higher fixed costs associated with a new plant and maintenance expense
resulting from turnarounds at three plants. Additional offsets included lower
methyl tertiary butyl ether (MTBE) margins, primarily in Europe and lower
overall propylene oxide (PO) and derivative margins as a result of lower margins
for new products and continued weakness in the European economy.

The 1992 earnings improved, compared to 1991, as a result of higher sales
volumes and margins. Sales volumes for all major product groups, including PO
derivatives and MTBE, were higher in 1992 than 1991. PO margins were higher in
1992, primarily in Europe, reflecting a weaker dollar. MTBE sales volumes were
higher in 1992, primarily in the U.S., as a result of higher demand from
domestic gasoline refiners. MTBE margins were higher on average in 1992 in both
the U.S. and Europe as a result of lower raw material costs.

ARCO Chemical's reported 1991 results included a $153 million before tax benefit
from business interruption insurance related to a plant accident and to
feedstock contamination at another plant in 1990. Also included in 1991 results
were net pretax charges totaling $20 million reflecting personnel reductions and
future environmental remediation costs, partially offset by a benefit related to
a change in estimated accident charges.

LYONDELL PETROCHEMICAL COMPANY

ARCO's 49.9 percent equity share of Lyondell's net income was $13 million for
1993, $8 million for 1992 and $111 million for 1991. Lyondell's results in 1993
improved as a result of higher margins attained through the processing of
greater volumes of Venezuelan crude oil. Lyondell's 1992 earnings, compared to
1991, were lower as a result of lower olefins margins and volumes and reduced
refining margins in the Gulf Coast.

UNALLOCATED EXPENSES AND OTHER

Unallocated expenses and other was a net after-tax expense of $140 million in
1993 and $60 million in 1991 compared to a net after-tax benefit of $25 million
in 1992. The increase in unallocated expenses in 1993, compared to 1992,
reflected the absence of a $111 million after-tax gain recognized in 1992,
increased employee-related expenses, higher charges for future environmental
remediation, and lower net investment income. In 1992, unallocated expenses and
other included the recognition of a $111 million after-tax gain representing a
previously deferred portion of the gain from the 1989 sale of a majority
interest in Lyondell, partially offset by corporate staff expense and charges
for future environmental remediation. The 1991 unallocated expenses and other
included after-tax charges of $34 million for future environmental remediation
and higher insurance costs.

RECENT DEVELOPMENTS

On January 28, 1994, Vastar Resources, Inc. (Vastar), a wholly owned subsidiary
of ARCO, filed a registration statement on Form S-1 with the Securities and
Exchange Commission for the proposed sale of up to 17,250,000 shares of common
stock to the public. ARCO intends to retain 80,000,001 shares, or 82.3 percent
of Vastar's common stock. On December 7, 1993, Vastar borrowed $1.25 billion
under a revolving credit agreement with a group of banks at an initial interest
rate of 3.9 percent. The revolving line of credit is available until November
30, 1996.

FINANCIAL POSITION AND LIQUIDITY

Cash flows from operating activities were $2.8 billion in 1993, $3.1 billion in
1992 and $3.0 billion in 1991. The net cash used in investing activities was
$2.2 billion in 1993 and primarily included expenditures for additions to fixed
assets (including dry hole costs) of $2.1 billion, proceeds from asset sales of
$582 million and a net increase in short-term investments of $789 million. The
net cash used in financing activities was $431 million in 1993 and primarily
included repayments of long-term debt of $886 million, proceeds of $1.3 billion
from the issuance of long-term debt and dividend payments of $879 million.

Cash and cash equivalents and short-term investments totaled $3.7 billion at
year-end 1993 and short-term borrowings were $1.5 billion. Working capital was
$1.1 billion higher at the end of 1993, reflecting an increase in

                                     35
<PAGE>
 
short-term investments and a decrease in long-term debt due within one year. At
December 31, 1993, the Corporation had unused committed bank credit facilities
totaling $3.2 billion. In addition, ARCO Chemical had unused bank credit
facilities totaling $300 million.

The Corporation's 1994 capital spending program includes $1.9 billion for
additions to fixed assets. Future capital expenditures remain subject to
business conditions affecting the industry, particularly changes in price and
demand for crude oil, natural gas and petroleum products. Changes in the tax
laws, the imposition of and changes in federal and state clean air and clean
fuel requirements, and other changes in environmental rules and regulations may
also affect future capital expenditures.

It is expected that future cash requirements for capital expenditures, dividends
and debt repayments will come from cash generated from operating activities,
existing cash balances, and any asset sales and future financings.

ENVIRONMENTAL MATTERS

During 1993, the Corporation charged to income $172 million before tax for 
environmental remediation costs and made related payments of $206 million. At 
December 31, 1993, the environmental remediation reserve totaled $648 million. 
The amount reserved represents an estimate of the undiscounted costs which the 
Corporation will incur to remediate sites with known contamination. In view of 
the uncertainties associated with estimating these costs, such as uncertainties 
with respect to the appropriate method for remediating contaminated sites, the 
extent of contamination at various sites, and the Corporation's ultimate share 
of costs at various sites, actual future costs could exceed the amount accrued 
by as much as $1 billion.

Although the contingencies associated with environmental matters could result in
significant expenses or judgments that, if aggregated and assumed to occur
within a single fiscal year, would be material to the Corporation's results of
operations, the likelihood of such occurrence is considered remote. On the basis
of management's best assessment of the ultimate amount and timing of these
events, such expenses or judgments are not expected to have a material adverse
effect on the Corporation's consolidated financial position, stockholders'
equity, liquidity or capital resources.

In addition to the provision for environmental remediation costs, $788 million 
has been accrued for the estimated cost, net of salvage value, of dismantling 
facilities as required by contract, regulation or law, and the estimated costs 
of restoration and reclamation of land associated with such facilities.

For further discussion of environmental matters see Note 12 of Notes to 
Consolidated Financial Statements.

EFFECTS OF INFLATION

While the annual rate of inflation remained moderate during the three-year 
period ended December 31, 1993, the Corporation continued to experience certain 
inflationary effects. The Corporation will achieve some benefits by using 
current, inflated dollars to satisfy its debt obligations and other monetary 
liabilities, because the Corporation's monetary assets are less than its 
monetary liabilities at December 31, 1993.

Based on the age of the Corporation's property, plant and equipment, it is 
estimated that the replacement cost of those assets is greater than the 
historical cost reflected in the Corporation's financial statements. 
Accordingly, the Corporation's depreciation, depletion and amortization expense 
for the three years ended December 31, 1993, would be greater if the expense 
were stated on a current-cost basis.

To the extent that the Corporation uses the last-in, first-out (LIFO) inventory
accounting method, the replacement cost of inventory is greater than the
historical cost reflected on the Corporation's balance sheet, while the costs of
products sold reflected in the Corporation's income statement approximate
current cost.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Stockholders and Board of Directors of Atlantic Richfield Company
 
  We have audited the accompanying consolidated balance sheets of Atlantic
Richfield Company as of December 31, 1993 and 1992, and the related
consolidated statements of income and retained earnings and cash flows for
each of the three years in the period ended December 31, 1993 and the related
financial statement schedules listed in the index on page 37 of this Form 10-
K. These financial statements and financial statement schedules are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements and financial statement schedules
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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Atlantic
Richfield Company as of December 31, 1993 and 1992, and the consolidated
results of its operations and its cash flows for each of the three years in
the period ended December 31, 1993, in conformity with generally accepted
accounting principles. In addition, in our opinion, the financial statement
schedules referred to above, when considered in relation to the basic
financial statements taken as a whole, present fairly, in all material
respects, the information required to be included therein.
 
  As discussed in Note 3 to the consolidated financial statements, the Company
changed its method of accounting for income taxes, postretirement benefits
other than pensions and postemployment benefits in 1992.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 Accounting Policies

ARCO's accounting policies conform to generally accepted accounting principles,
including the "successful efforts" method of accounting for oil and gas
producing activities.

Principles of Consolidation

The consolidated financial statements include the accounts of all subsidiaries,
ventures and partnerships in which a controlling interest is held, including
ARCO Chemical Company (ACC), of which ARCO owned 83.3 percent of the outstanding
shares at December 31, 1993. ARCO also consolidates its interests in undivided
interest pipeline companies and in oil and gas and coal mining joint ventures.
ARCO uses the equity method of accounting for companies where its ownership is
between 20 and 50 percent and for other ventures and partnerships in which less
than a controlling interest is held.

Cash Equivalents; Short-Term Investments

Cash equivalents consist of highly liquid investments, such as time deposits,
certificates of deposit and marketable securities other than equity securities,
maturing within three months of purchase. Short-term investments consist of
similar investments maturing in more than three months of purchase. Cash
equivalents and short-term investments are stated at cost, which approximates
market value.

Oil and Gas Unproved Property Costs

Unproved property costs are capitalized and amortized on a composite basis,
considering past success experience and average property life. In general, costs
of properties surrendered or otherwise disposed of are charged to accumulated
amortization. Costs of successful properties are transferred to developed
properties.

Fixed Assets

Fixed assets are recorded at cost and are written off on either a unit-of-
production method or a straight-line method based on the expected lives of
individual assets or groups of assets.

Upon disposal of assets depreciated on an individual basis, residual cost less
salvage is included in current income. Upon disposal of assets depreciated on a
group basis, unless unusual in nature or amount, residual cost less salvage is
charged against accumulated depreciation.

Dismantlement, Restoration and Reclamation Costs

The estimated costs, net of salvage value, of dismantling facilities or projects
with limited lives or facilities that are required to be dismantled by contract,
regulation or law, and the estimated costs of restoration and reclamation
associated with oil and gas and mining operations are accrued during production
and classified as a long-term liability. Such costs are taken into account in
determining the cost of production in all operations, except oil and gas
production, in which case such costs are considered in determining depreciation,
depletion and amortization.

Environmental Remediation

Environmental remediation costs are accrued as operating expenses based on the
estimated timing and extent of remedial actions required by applicable
governmental authorities, experience gained from similar sites on which
remediation has been completed, and the amount of ARCO's liability in
consideration of the proportional liability and financial wherewithal of other
responsible parties. Estimated liabilities are not discounted to present value.

Reclassifications

Certain previously reported amounts have been restated to conform to
classifications adopted in 1993.

NOTE 2 Unusual Items

In the fourth quarter of 1993, ARCO announced a reorganization of its Lower 48
oil and gas operations. ARCO provided as unusual items a pretax charge of $659
million, $404 million after tax, primarily related to the writedown for sale or
other disposition of oil and gas properties and excess office space, in addition
to workforce reductions.

In the fourth quarter of 1992, ARCO recognized a pretax benefit of $149 million
from the settlement with Iran related to Corporation assets that had been
nationalized in the late 1970s. In the second quarter of 1992, ARCO recognized a
pretax benefit of $178 million related to a portion of the gain from the 1989
sale of a majority interest in Lyondell Petrochemical Company (Lyondell) which
was previously deferred as the amount equal to ARCO's guarantee of notes
associated with certain of Lyondell's manufacturing facilities. When Lyondell
repaid the notes in 1992, ARCO was released from its guarantee and accordingly
recognized the gain. In the second quarter of 1992, ARCO also recognized a
pretax charge of $56 million resulting from ACC's withdrawal from the YUKONG
ARCO Chemical Ltd. joint venture in Korea. The net benefit related to 1992
unusual items was $211 million after tax.

In 1991, ARCO announced a reorganization of its oil and gas operations in the
Lower 48 states and a companywide workforce reduction. An estimated pretax
charge of $281 million was provided as unusual items for the

                                      42
<PAGE>

cost of these programs. ARCO also provided as unusual items a pretax charge of
approximately $222 million for the anticipated loss on the sale of certain Lower
48 oil and gas properties and the writedown of certain coal assets. The net
provision related to the above items was $312 million after tax.

NOTE 3 Accounting Changes

Effective January 1, 1992, ARCO implemented on the immediate recognition basis
Statement of Financial Accounting Standards (SFAS) No. 106, "Employers'
Accounting for Postretirement Benefits Other Than Pensions," which requires
accrual of the actuarially determined costs of postretirement benefits during
the years that the employee renders the necessary service. ARCO's previous
policy was to expense these costs when incurred.

The cumulative effect of adopting SFAS No. 106 as of January 1, 1992, resulted
in a charge of $435 million, or $2.70 per share, to 1992 earnings, net of income
tax effects of approximately $262 million.

Effective January 1, 1992, ARCO adopted SFAS No. 109, "Accounting for Income
Taxes." The cumulative effect of the change on 1992 net income was a benefit of
$43 million, or $0.27 per share. The effect of adopting SFAS Nos. 106 and 109 on
1992 net income, excluding the cumulative effect, was not material.

Effective January 1, 1992, ARCO also adopted SFAS No. 112, "Employers'
Accounting for Postemployment Benefits." The standard requires companies to
accrue the cost of postemployment benefits either during the years that the
employee renders the necessary service or at the date of the event giving rise
to the benefit, depending upon whether certain conditions are met. The effect of
adoption did not have a material impact on 1992 net income.

NOTE 4 Segment Information

ARCO operates primarily in the Resources and Products segments. The Resources
segment includes oil and gas operations, which comprise the exploration,
development and production of petroleum, including petroleum liquids (crude oil,
condensate and natural gas liquids) and natural gas; the purchase and sale of
petroleum liquids and natural gas; and the mining and sale of coal. The Products
segment includes the refining and transportation of petroleum and petroleum
products; the marketing of petroleum products; and the manufacture and sale of
intermediate chemicals and specialty products, including propylene oxide and
derivatives, tertiary butyl alcohol, methyl tertiary butyl ether and styrene
monomer.

Segment information for the years ended December 31, 1993, 1992 and 1991 was as
follows:

NOTE 5 Inventories

Inventories are recorded when purchased, produced or manufactured and are stated
at the lower of cost or market. In 1993, approximately 88 percent of inventories
excluding materials and supplies were determined by the last-in, first-out
(LIFO) method. Materials and supplies and other non-LIFO inventories are
determined predominantly on an average cost basis.

Total inventories at December 31, 1993 and 1992 comprised the following

</TABLE>

Maturities and sinking fund obligations for the five years subsequent to
December 31, 1993 are as follows (millions of dollars): 1994--$165; 1995--$632;
1996--$1,434; 1997--$269; 1998--$182. No material amounts of long-term debt are
collateralized by Corporation assets.

Vastar Resources, Inc. (Vastar), a wholly owned subsidiary of ARCO, entered into
a $1.25 billion unsecured, variable rate, revolving-term credit agreement. In
December 1993, Vastar borrowed $1.25 billion principal amount at an initial
interest rate of 3.9 percent. The agreement contains restrictions 

which, among other things, require Vastar to maintain certain financial ratios
and restrict encumbrance of assets.


NOTE 8 Bank Credit Facilities and Compensating Balances

In 1993, ARCO and certain wholly owned subsidiaries had committed bank credit
facilities of approximately $3.2 billion, including a credit facility negotiated
on behalf of a subsidiary that is denominated in pounds sterling. At December
31, 1993, there were no borrowings under these committed facilities.

ACC maintains two credit facilities under which it may borrow up to $300 million
which are not guaranteed by ARCO. At December 31, 1993, there were no borrowings
against the ACC credit facilities. The facilities replace a previous facility
that effectively expired in December 1993.

Notes payable on the balance sheet consist primarily of commercial paper issued
to a variety of financial investors and institutions and any amounts outstanding
under ARCO or ACC credit facilities.

ARCO has no requirements for compensating balances. ARCO does maintain balances
for some of its banking services and products. Such balances are solely at
ARCO's discretion, so that on any given date, none of ARCO's cash is restricted.

At December 31, 1993, ARCO had letters of credit outstanding totalling $305
million.

NOTE 9 Interest Expense

Interest expense for the years ended December 31, 1993, 1992 and 1991 was
comprised of the following:

Expenses for maintenance and repairs for 1993, 1992 and 1991 were $509 million,

NOTE 12 Other Commitments and Contingencies

ARCO has commitments, including those related to the acquisition, construction
and development of facilities, all made in the normal course of business.

At December 31, 1993 and 1992, there were contingent liabilities primarily with
respect to guarantees of securities of other issuers of approximately $111
million and $100 million, respectively, of which approximately $41 million and
$45 million, respectively, were indemnified.

Following the March 1989 EXXON VALDEZ oil spill, Alyeska Pipeline Service
Company (Alyeska) and Alyeska's owner companies were the subject of numerous
lawsuits by the State of Alaska, the United States and private plaintiffs. ARCO
Transportation Alaska, Inc. (ATA) owns approximately 21 percent of Alyeska. In
July 1993, it was announced that Alyeska and its owner companies had agreed to
pay $98 million in settlement of all but a handful of the lawsuits by private
plaintiffs of which $20.9 million was ATA's share. At the October 1993 approval
hearing on the settlement, the settlement was tentatively approved; however,
there remain certain issues concerning claims that Exxon might assert against
Alyeska and its owner companies that must be resolved before the settlement
becomes final.

ARCO and former producers of lead pigments have been named as defendants in
cases filed by a municipal housing authority, a purported class and several
individuals seeking damages and injunctive relief as a consequence of the
presence of lead-based paint in certain housing units.

ARCO and its subsidiary, Atlantic Richfield Hanford Company (ARHCO), and several
other companies have been named as defendants in lawsuits filed on behalf of
individual persons and a number of purported classes. These lawsuits arise out
of radioactive and non-radioactive toxic and hazardous substances allegedly
generated at the Hanford Nuclear Reservation in Richland, Washington (HNR). The
claims against ARCO and ARHCO arise out of the performance by ARHCO of a
contract with the Atomic Energy Commission to provide chemical processing, waste
management and support services at HNR from 1967 to 1977. ARCO and ARHCO believe
that, should either or both ultimately be held liable, they will be entitled to
indemnification by the federal government as provided under the Price-Anderson
Act, and pursuant to the terms of the contract between ARHCO and the Atomic
Energy Commission.

ARCO is also the subject of or party to a number of pending or threatened legal
actions for which the legal responsibility and financial impact cannot presently
be ascertained. Although any ultimate liability arising from any of these suits,
or from any of the proceedings described above, if aggregated and assumed to
occur in a single fiscal year, would be material to ARCO's results of
operations, the likelihood of such occurrence is considered remote. On the basis
of management's best assessment of the ultimate amount and timing of these
events, such expenses or judgments are not expected to have a material adverse
effect on ARCO's consolidated financial position, stockholders' equity,
liquidity or capital resources.

ARCO is subject to other loss contingencies pursuant to federal, state and local
environmental laws and regulations. These include possible obligations to remove
or mitigate the effects on the environment of the disposal or release of certain
chemical, mineral and petroleum substances at various sites, including the
restoration of natural resources located at these sites and damages for loss of
use and non-use values. ARCO is currently participating in environmental
assessments and cleanups under these laws at federal Superfund and state-managed
sites, as well as other clean-up sites, including service stations, refineries,
terminals, chemical facilities, third-party landfills, former nuclear processing
facilities, and sites

                                      47
<PAGE>
 
associated with discontinued operations. ARCO may in the future be involved in
additional environmental assessments and cleanups, including the restoration of
natural resources and damages for loss of use and non-use values. The amount of
such future costs is indeterminable due to such factors as the unknown nature
and extent of contamination at many sites, the unknown timing, extent and method
of the remedial actions which may be required and the determination of ARCO's
liability in proportion to other responsible parties.

ARCO continues to estimate the amount of these costs in periodically
establishing reserves based on progress made in determining the magnitude of
remediation costs, experience gained from sites on which remediation has been
completed, the timing and extent of remedial actions required by the applicable
governmental authorities and an evaluation of the amount of ARCO's liability
considered in light of the liability and financial wherewithal of the other
responsible parties. At December 31, 1993, the reserve balance is $648 million.
As the scope of ARCO's obligations becomes more clearly defined, there may be
changes in these estimated costs, which might result in future charges against
ARCO's earnings.

ARCO's reserve covers federal Superfund and state-managed sites as well as other
clean-up sites, including service stations, refineries, terminals, chemical
facilities, third-party landfills, former nuclear processing facilities and
sites associated with discontinued operations. ARCO has been named a potentially
responsible party (PRP) for 123 sites. The number of PRP sites in and of itself
does not represent a relevant measure of liability, because the nature and
extent of environmental concerns varies from site to site and ARCO's share of
responsibility varies from sole responsibility to very little responsibility.
ARCO reviews all of the PRP sites, along with other sites as to which no claims
have been asserted, in estimating the amount of the reserve. ARCO's future costs
at these sites could exceed the reserve by as much as $1 billion.

Approximately half of the reserve related to sites associated with ARCO's
discontinued operations, primarily mining activities in the states of Montana
and Colorado. Another significant component related to currently and formerly
owned chemical, nuclear processing, and refining and marketing facilities, and
other sites which received wastes from these facilities. The remainder related
to other sites with reserves ranging from $1 million to $10 million per site. No
one site represents more than 15 percent of the total reserve. Substantially all
amounts accrued in the reserve are expected to be paid out over the next five to
six years.

Claims for recovery of remediation costs already incurred and to be incurred in
the future have been filed against various insurance companies and other third
parties. None of these claims has been resolved. Due to the uncertainty as to
ultimate recovery from these parties, ARCO has neither recorded any asset nor
reduced any liability in anticipation of such recovery.

Environmental loss contingencies also include claims for personal injuries
allegedly caused by exposure to toxic materials manufactured or used by ARCO.
Although these contingencies could result in significant expenses or judgments
that, if aggregated and assumed to occur within a single fiscal year, would be
material to ARCO's results of operations, the likelihood of such occurrence is
considered remote. On the basis of management's best assessment of the ultimate
amount and timing of these events, such expenses or judgments are not expected
to have a material adverse effect on ARCO's consolidated financial position,
stockholders' equity, liquidity or capital resources.

The operations and consolidated financial position of ARCO continue to be
affected from time to time in varying degrees by domestic and foreign political
developments as well as legislation, regulations and litigation pertaining to
restrictions on production, imports and exports, tax increases, environmental
regulations, cancellation of contract rights and expropriation of property. Both
the likelihood of such occurrences and their overall effect on ARCO vary greatly
and are not predictable.

These uncertainties are part of a number of items that ARCO has taken and will
continue to take into account in periodically establishing reserves.

NOTE 13 Retirement Plans

ARCO and its subsidiaries have defined benefit pension plans to provide pension
benefits to substantially all employees. The benefits are based on years of
service and the employee's compensation, primarily during the last three years
of service. ARCO's funding policy is to make annual contributions as required by
applicable regulations. ARCO charges pension costs as accrued, based on an
actuarial valuation for each plan, and funds the plans through contributions to
trust funds that are kept apart from Corporation funds.

NOTE 14 Other Postretirement Benefits

ARCO and its subsidiaries sponsor defined postretirement benefit plans to
provide other postretirement benefits to substantially all employees who retire
with ARCO having rendered the required years of service, along with their
spouses and eligible dependents. Health care benefits are provided primarily
through comprehensive indemnity plans. Currently, ARCO pays approximately 80
percent of the cost of such plans, but has the right to modify the cost-sharing
provisions at any time. Life insurance benefits are based primarily on the
employee's final compensation and are also partially paid for by retiree
contributions, which vary based upon coverage chosen by the retiree.

ARCO's current policy is to fund the cost of postretirement health care and life
insurance plans on a pay-as-you-go basis. Pursuant to Section 401(h) of the
Internal Revenue Code of 1986, excess pension assets totalling $21 million were
transferred from the pension plans to health care benefit accounts within the
pension plans for reimbursement of 1992 retiree health care benefits.

The following table sets forth the plans' combined postretirement benefit
liability as of December 31, 1993 and 1992:

In addition to the cost above, ARCO recorded $9 million as additional
postretirement benefit expense in connection with the workforce reduction in
1993.

For the year ended December 31, 1991, ARCO recognized postretirement costs as
incurred. Accordingly, the amount recognized as expense in prior years is not
comparable.

The significant assumptions used in determining postretirement benefit cost and
the accumulated postretirement benefit obligation were as follows:

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

The weighted average annual assumed rate of increase in the per capita cost of
covered benefits (i.e., health care trend rate) for the health plans is 10
percent for 1993 to 1996, 8 percent for 1997 to 2001, and 6 percent thereafter.
The effect of a one-percentage-point increase in the assumed health care cost
trend rate would increase the accumulated postretirement benefit obligation as
of December 31, 1993, by approximately 10.5 percent, and the aggregate of the
service and interest cost components of net annual postretirement benefit cost
by approximately 11 percent.

The changes in preference stocks outstanding were due solely to conversions. The
$3.00 cumulative convertible preference stock is convertible into 6.8 shares of
common stock. The $2.80 cumulative convertible preference stock is convertible
into 2.4 shares of common stock. The common stock is subordinate to the
preference stocks for dividends and assets. The $3.00 and $2.80 preference
stocks may be redeemed at the option of ARCO for $82 and $70 per share,
respectively.

ARCO has authorized 75,000,000 shares of preferred stock, $.01 par, of which
none were issued or outstanding at December 31, 1993.

By stockholder approval, all of the Series B, 3.75 percent cumulative preferred
stock, $100 par, of which none were issued and outstanding, was cancelled
effective May 3, 1993.

By Board authorization, effective December 31, 1991, ARCO canceled 7 million
shares of common stock held in treasury. As a result of this cancellation,
common stock decreased by $17 million, capital in excess of par value of stock
decreased by $30 million, and retained earnings decreased by $684 million in
1991.

The balance in ARCO's common stock at December 31, 1993, 1992 and 1991 was $402
million.

The net decrease in capital in excess of par value of stock in 1993, 1992 and
1991 of $15 million, $12 million and $52 million, respectively, was due
primarily to the conversion of preference stock to common stock and the
cancellation of treasury stock in 1991.

ARCO's Certificate of Incorporation contains a provision restricting dividend
payments; however, at December 31, 1993, retained earnings were free from such
restriction. At December 31, 1993, shares of ARCO's authorized and unissued
common stock were reserved as follows:

NOTE 21 Financial Instruments; Fair Value and Off-Balance-Sheet Risk

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments:

The carrying amount of cash equivalents, short-term investments and notes
payable approximates fair value because of the short maturity of those
instruments.

The fair value of other investments and long-term receivables was estimated
primarily based on quoted market prices for those or similar investments. At
December 31, 1993 and 1992, the fair value of other investments and long-term
receivables approximated carrying value.

The fair value of ARCO's long-term debt was estimated based on the quoted market
prices for the same or similar issues or on the current rates offered to ARCO
for debt of the same remaining maturities. At December 31, 1993 and 1992, the
fair value of long-term debt, including long-term debt due within one year, was
$8,307 million and $7,570 million, respectively.

The fair value of foreign currency forward contracts and derivatives was
estimated by obtaining quotes from brokers. Fair value of these instruments at
December 31, 1993 and 1992, approximated carrying value.

At December 31, 1993 and 1992, ARCO had foreign currency forward contracts and
foreign cross-currency contracts outstanding, which mature at various dates, to
reduce exposure to foreign currency exchange risk. The aggregate contract value
of instruments used to buy U.S. dollars in exchange for Australian dollars was
approximately $483 million and $367 million at December 31, 1993 and 1992,
respectively. The aggregate contract value of instruments used to sell European
currencies and Japanese yen in exchange for Deutsche marks, U.S. dollars and
functional currencies of ARCO's European operations was approximately $24
million and $65 million at December 31, 1993 and 1992, respectively.
Additionally, ARCO had outstanding foreign currency swaps which mature at
various dates through 1994, to sell approximately 187 million French francs for
$35 million at both December 31, 1993 and 1992.

                                      52
<PAGE>

At December 31, 1993 and 1992, approximately $355 million and $405 million,
respectively, of the long-term debt was denominated in foreign currencies. To
reduce the exposure to foreign currency fluctuations, ARCO entered into a swap
agreement on an 18 billion yen debt issue due in 1996 which fixes the principal
balance at $102 million with an effective rate of 8.14 percent. At December 31,
1993, ARCO had outstanding interest rate swaps on two loans totalling 300
million Dutch guilders due in 1997 (one loan for 150 million Dutch guilders in
1992). This effectively changed both loans' floating interest rates to fixed
rates of 5.70 percent and 6.71 percent (9.69 percent in 1992).

The counterparties to these transactions are major international financial
institutions; ARCO does not anticipate nonperformance by the counterparties.

SUPPLEMENTAL INFORMATION (UNAUDITED)

Oil and Gas Producing Activities

The Securities and Exchange Commission (SEC) defines proved oil and gas reserves
as those estimated quantities of crude oil, natural gas, and natural gas liquids
that geological and engineering data demonstrate with reasonable certainty to be
recoverable in future years from known reservoirs under existing economic and
operating conditions. Proved developed oil and gas reserves are reserves that
can be expected to be recovered through existing wells with existing equipment
and operating methods.

ARCO reports reserve estimates to various federal government agencies and
commissions. These estimates may cover various regions of crude oil and natural
gas classifications within the United States and may be subject to mandated
definitions. There have been no reports of total ARCO reserve estimates
furnished to federal government agencies or commissions which vary from those
reported to the SEC since the beginning of the last fiscal year.

Estimated quantities of ARCO's proved oil and gas reserves were as follows:

</TABLE>

Significant changes to proved oil and gas reserves during 1993 were due to the
addition of reserves from the Sirasun gas discovery in Indonesia, the Mustang
Island gas discovery offshore Gulf of Mexico and the sale of Lower 48 oil and
gas properties.

Estimates of petroleum reserves have been made by ARCO engineers. These
estimates include reserves in which ARCO holds an economic interest under
production-sharing and other types of operating agreements with foreign
governments. These estimates do not include probable or possible reserves.
Natural gas liquids comprise 12 percent of petroleum liquid proved reserves.

The sale of natural gas from the North Slope of Alaska, which is not used in
providing fuel in North Slope operations or sold to others on the North Slope,
is dependent upon construction of a natural gas transportation system or another
marketing alternative. Such gas is not

                                      54

included in ARCO's reserves. There are currently several projects under
consideration, including the Alaska Natural Gas Transportation System and the
Trans Alaska Gas System. However, there are a number of regulatory, financial,
legal and marketing questions regarding the projects that remain unresolved.

ARCO has studied various options for marketing North Slope gas over the past few
years. However, ARCO Alaska believes that market conditions are not likely to
permit implementation of any large gas sales project within the foreseeable
future.

The aggregate amounts of capitalized costs relating to oil and gas producing
activities and the related accumulated depreciation, depletion and amortization
as of December 31, 1993, 1992 and 1991 were as follows:

Notes to Consolidated Financial Statements is primarily marketing-related 
activities and the exclusion of gains

on property sales and unusual items related to the Lower 48 reorganization.

Information for 1992 and 1991 has been restated to conform to 1993 formats,
primarily the reclassification of allocated overhead from production and
exploration costs to other operating expenses and the removal of certain unusual
items previously included.

</TABLE>

Estimated future cash inflows are computed by applying year-end prices of oil
and gas to year-end quantities of proved reserves. Future price changes are
considered only to the extent provided by contractual arrangements. Estimated
future development and production costs are determined by estimating the
expenditures to be incurred in developing and producing the proved oil and gas
reserves at the end of the year, based on year-end costs and assuming
continuation of existing economic conditions. Estimated future income tax
expense is calculated by applying year-end statutory tax rates (adjusted for
permanent differences and tax credits) to estimated future pretax net cash flows
related to proved oil and gas reserves, less the tax basis of the properties
involved.

These estimates are furnished and calculated in accordance with requirements of
the Financial Accounting Standards Board and the SEC. Because of unpredictable
variances in expenses and capital forecasts, crude oil and natural gas price
changes, largely influenced and controlled by U.S. and foreign governmental
actions, and the fact that the bases for such estimates vary significantly,
management believes the usefulness of these projections is limited. Estimates of
future net cash flows presented do not represent management's assessment of
future profitability or future cash flow to ARCO. Management's investment and
operating decisions are based on reserve estimates that include proved reserves
prescribed by the SEC as well as probable reserves, and on different price and
cost assumptions from those used here.

                                      56
<PAGE>

It should be recognized that applying current costs and prices and a 10 percent
standard discount rate does not convey absolute value. The discounted amounts
arrived at are only one measure of the value of proved reserves.

Regarding the information on estimated reserve quantities and discounted future
net cash flows, ARCO has no long-term supply contracts to purchase from foreign
governments or any interest in equity affiliates involved in oil and gas
producing activities.

B. PREFERRED STOCK

          The Board of Directors is authorized, subject to any limitations
prescribed by law, to provide for the issuance of the shares of Preferred Stock
in series, and by filing a certificate pursuant to the applicable law of the
State of Delaware, to establish from time to time the number of shares to be
included in each such series, and to fix a designation, powers, preferences, and
rights of the shares of each such series and any qualifications, limitations or
restrictions thereof; provided, however, that the Preferred Stock shall be
subordinate as to dividends and rights upon liquidation, dissolution and winding
up to the $3.00 Preference Stock and the $2.80 Preference Stock. The number of
authorized shares of Preferred Stock may be increased or decreased (but not
below the number of shares thereof than outstanding) by the affirmative vote of
the holders of stock of the Company entitled to vote thereon having a majority
of the votes entitled to be cast, without a vote of the holders of the Preferred
Stock, or of any series thereof, unless a vote of any such holders is required

C. PREFERENCE STOCK

1. ISSUANCE OF PREFERENCE STOCK.

          The Company is authorized to issue the following two classes of
 Preference Stock:

          $3.00 Preference Stock

          $2.80 Preference Stock

          A. The shares of $3.00 Preference Stock may be divided into and issued
in series. Each series shall be so designated as to distinguish the shares
thereof from the shares of all other series. All shares of $3.00 Preference
Stock shall be identical except as to the relative rights and preferences, set
forth in this Certificate. There may be variations between different series,
namely, the amount payable upon shares in the event of liquidation of the
Company and the price or prices at which shares may be redeemed.

          The Board of Directors is hereby expressly vested with authority, by
resolution, to divide the $3.00 Preference Stock into series and, within the
limitations prescribed by law and by this Certificate, to fix and determine at
the time of the establishment of any series the relative rights and preferences
of any series so established.

          The series of the authorized shares of $3.00 Preference Stock of the
Company designated $3.00 Cumulative Convertible Preference Stock shall consist
of ninety-four thousand, three hundred sixteen (94,316) shares; and the shares
of said series shall have, in addition to the rights and preferences granted by
law and by the other provisions of this Certificate, the following relative
rights and preferences:

          (i) The amount which, in the event of voluntary or involuntary
     liquidation of the Company, shall be payable for shares of said series
     prior to any payment to the holders of Common Stock or of any other class
     of stock of the Company ranking as to assets subordinate to the $3.00 
     Preference Stock shall be Eighty Dollars ($80.00) for each share of said 
     series (in addition to accrued and unpaid dividends).

          (ii) The price for each share at which shares may be redeemed at the
     option of the Company is Eighty-Two Dollars ($82.00).

          B. The authorized shares of $2.80 Preference Stock shall have, in
addition to the rights and preferences granted by law and by the other
provisions of this Certificate, the following rights and preferences:

          (i) The amount which, in the event of voluntary or involuntary
     liquidation of the Company, shall be payable for said shares prior to any
     payment to the holders of Common Stock or any other class of stock of the
     Company ranking as to assets subordinate to the $2.80 Preference Stock 
     shall be Seventy Dollars ($70.00) for each share (in addition to accrued
     and unpaid dividends).

          (ii) The price for each share at which shares may be redeemed at 
     the option of the Company is Seventy Dollars ($70.00).

                                       2

2. DIVIDENDS.

          The holders of shares of Preference Stock shall be entitled to
receive, when and as declared by the Board of Directors, dividends at the rate
of Three Dollars ($3.00) per share per year for $3.00 Preference Stock and at
the rate of Two Dollars and Eighty Cents ($2.80) per share per year for $2.80
Preference Stock, and no more, payable quarterly on the twentieth day of each
March, June, September and December. Such dividends shall be cumulative from the
quarterly dividend payment date next preceding the date of issue of each share,
unless the date of issue is a quarterly dividend payment date or a date between
the record date for the determination of holders of Preference Stock entitled to
receive a quarterly dividend and the date of payment of such quarterly dividend,
in either of which events such dividends shall be cumulative from such quarterly
dividend payment date. In case dividends for any quarterly dividend period are
not paid in full, all shares of Preference Stock and all shares of any class or
classes of stock of the Company ranking as to dividends on a parity with the
Preference Stock shall participate ratably in the payment of dividends for such
period in proportion to the full amounts of dividends for such period to which
they are respectively entitled. No dividends shall be paid or set apart for
payment or declared on the Common Stock or on any other class of stock of the
Company ranking as to dividends subordinate to the Preference Stock (other than
dividends payable in Common Stock or in any other class of stock of the Company
ranking as to dividends and assets subordinate to the Preference Stock or
dividends paid or set apart for payment or declared in order to comply with law
or with a governmental or court order or decree), and no payment shall be made
to any sinking fund for any class of stock of the Company ranking as to
dividends or assets on a parity with or subordinate to the Preference Stock,
until dividends payable for all past quarterly dividend periods on all
outstanding shares of Preference Stock have been paid, or declared and set apart
for payment, in full.

3. LIQUIDATION OF THE COMPANY.

          In the event of voluntary or involuntary liquidation of the Company,
the holders of shares of Preference Stock shall be entitled to receive from the
assets of the Company (whether capital or surplus), prior to any payment to the
holders of Common Stock or of any other class of stock of the Company ranking as
to assets subordinate to the Preference Stock, the amount per share which shall
have been fixed and determined with respect to such Preference Stock plus an
amount equal to the accrued and unpaid dividends thereon computed to the date on
which payment thereof is made available, whether or not earned or declared.
After such payments to the holders of shares of Preference Stock, any balance
then remaining shall be paid to the holders of the Common Stock or of any other
class of stock of the Company ranking as to assets subordinate to the Preference
Stock, as they may be entitled. If, upon liquidation of the Company, its assets
are not sufficient to pay in full the amounts so payable to the holders of
shares of Preference Stock, all shares of Preference Stock shall participate
ratably in the distribution of assets in proportion to the full amounts to which
they are respectively entitled.

4. RANK.

          The Preferred Stock shall be subordinate with respect to dividends and
rights upon liquidation, dissolution or winding up to the Preference Stock.

5. CONVERSION PROVISIONS.

          (a) Shares of Preference Stock, may, at the option of the holder, be
converted into Common Stock of the Company (as such shares may be constituted on
the conversion date) at the rate of six and eight-tenths (6.8) shares of Common
Stock for each share of $3.00 Preference Stock, and at the rate of two and four-
tenths (2.4) shares of Common Stock for each share of $2.80 Preference Stock,
subject to adjustment as provided herein, provided that, as to any shares of
Preference Stock which shall have been called for redemption, the conversion
right shall terminate at the close of business on the fifth full business day
prior to the date fixed for redemption or at such later time as may be fixed by
the Board of Directors of the Company.

                                       3
<PAGE>
 
          (b) The holder of a share or shares of Preference Stock may exercise
the conversion right as  to any share or shares thereof by delivering to the
Company during regular business hours, at the office of any transfer agent of
the Company for the Preference Stock or at such other place as may be designated
by the Company, the certificate or certificates for the shares to be converted,
duly endorsed or assigned in blank or to the Company (if required by it),
accompanied by written notice stating that the holder elects to convert such
shares and stating the name or names (with address or addresses) in which the
certificate or certificates for Common Stock are to be issued. Conversion shall
be deemed to have been effected on the date when such delivery is made and such
date is referred to herein as the "conversion date." As promptly as practicable
thereafter the Company shall issue and deliver to or upon the written order of
such holder, at such office or other place designated by the Company, a
certificate or certificates for the number of full shares of Common Stock to
which the stockholder is entitled and a check, cash, scrip certificate or other
adjustment in respect of any fraction of a share as provided in subparagraph
5(d) below. The person in whose name the certificate or certificates for Common
Stock are to be issued shall be deemed to have become a stockholder of record on
the conversion date unless the transfer books of the Company are closed on that
date, in which event the stockholder shall be deemed to have become a
stockholder of record on the next succeeding date on which the transfer books
are open, but the conversion rate shall be that in effect on the conversion
date.

          (c) No payment or adjustment shall be made for dividends accrued on
any shares of Preference Stock converted or for dividends on any shares of
Common Stock issuable on conversion, but until all dividends accrued and unpaid
on such Preference Stock up to the quarterly dividend payment date next
preceding the conversion date shall have been paid to the holder of the shares
of Preference Stock converted or to his assigns, or declared and set apart for
such payment, in full, no dividends shall be paid or set apart for payment or
declared on the Common Stock or on any other class of stock of the Company
ranking as to dividends subordinate to the Preference Stock (other than
dividends payable in Common Stock or in any other class of stock of the Company
ranking as to dividends and assets subordinate to the Preference Stock or
dividends paid or set apart for payment or declared in order to comply with law
or with a governmental or court order or decree) and no payment shall be made to
any sinking fund for any class of stock of the Company ranking as to dividends
or assets on a parity with or subordinate to the Preference Stock.

          (d) The Company shall not be required to issue any fraction of a share
upon conversion of any share or shares of Preference Stock. If more than one
share of Preference Stock shall be surrendered for conversion at one time by the
same holder, the number of full shares of Common Stock issuable upon conversion
thereof shall be computed on the basis of the total number of shares of
Preference Stock so surrendered. If any fractional interest in a share of Common
Stock would be deliverable upon conversion, the Company shall make an adjustment
therefor in cash unless its Board of Directors shall have determined to adjust
fractional interests by issuance of scrip certificates or in some other manner.
Adjustment in cash shall be made on the basis of the current market value of one
share of Common Stock, which shall be taken to be the last reported sale price
of the Company's Common Stock on the New York Stock Exchange on the last
business day before the conversion date or, if there was no reported sale on
that day, the average of the closing bid and asked quotations on that Exchange
on that day or, if the Common Stock was not then listed on that Exchange, the
average of the lowest bid and the highest asked quotations in the over-the-
counter market on that day.

          (e) The issuance of Common Stock on conversion of Preference Stock
shall be without charge to the converting holder of Preference Stock for any tax
in respect of the issuance thereof, but the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of shares in any name other than that of the holder of record on
the books of the Company of the shares of Preference Stock converted, and the
Company shall not be required to issue or deliver any certificate for shares of
Common Stock unless and until the person requesting the issuance thereof shall
have paid to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid.

          (f) The conversion rates provided in subparagraph 5(a) shall be
subject to the following adjustments, which shall be made to the nearest one-
hundredth of a share of Common Stock or, if none to the next lower one-
hundredth:

                                       4
<PAGE>
 
          (i) If the Company shall pay to the holders of its Common Stock a
dividend in shares of Common Stock or in securities convertible into Common
Stock, the conversion rate in effect immediately prior to the record date fixed
for the determination of the holders of Common Stock entitled to such dividend
shall be proportionately increased, effective at the opening of business on the
next following full business day.

          (ii) If the Company shall split the outstanding shares of its Common
Stock into a greater number of shares or combine the outstanding shares into a
smaller number, the conversion rate in effect immediately prior to such action
shall be proportionately increased in the case of a split or decreased in the
case of a combination, effective at the opening of business on the full business
day next following the day such action becomes effective.

          (iii) If the Company shall issue to the holders of its Common Stock
rights or warrants to subscribe for or purchase shares of its Common Stock at a
price less than the Current Market Price (as defined below in this subparagraph)
of the Company's Common Stock at the record date fixed for the determination of
the holders of Common Stock entitled to such rights or warrants, the conversion
rate in effect immediately prior to said record date shall be increased,
effective at the opening of business on the next following full business day, to
an amount determined by multiplying such conversion rate by a fraction the
numerator of which is the number of shares of Common Stock of the Company
outstanding immediately prior to said record date plus the number of additional
shares of its Common Stock offered for subscription or purchase and the
denominator of which is said number of shares outstanding immediately prior to
said record date plus the number of shares of Common Stock of the Company which
the aggregate subscription or purchase price of the total number of shares so
offered would purchase at the Current Market Price of the Company's Common Stock
at said record date. Notwithstanding the preceding sentence, if the Established
Market Price (as defined below in this subparagraph) of the rights or warrants
in the case of a particular issue thereof is less than Thirty-seven and One-half
Cents ($0.375) per right or warrant in the case of $3.00 Preference Stock or is
less than One Dollar ($1.00) per right or warrant in the case of $2.80
Preference Stock, the increase in the conversion rate shall be postponed and the
amount of such Established Market Price shall be carried forward and applied as
provided in subparagraph 5(f)(v). As used in this subparagraph 5(f)(iii) the
term "Current Market Price" at said record date shall mean the average of the
daily last reported sale prices per share of the Company's Common Stock on the
New York Stock Exchange during the twenty (20) consecutive full business days
commencing with the thirtieth (30th) full business day before said record date,
provided that if there was no reported sale on any such day or days there shall
be substituted the average of the closing bid and asked quotations on that
Exchange on that day, and provided further that if the Common Stock was not
listed on that Exchange on any such day or days there shall be substituted the
average of the lowest bid and the highest asked quotations in the over-the-
counter market on that day. As used in this subparagraph 5(f)(iii) the term
"Established Market Price" of the rights or warrants shall mean the average of
the means between the reported high and low sale prices per right or warrant on
the New York Stock Exchange during the first three business days on which the
rights or warrants are traded on that Exchange, provided that if an over-the-
counter market for the rights or warrants is established on any day before they
are traded on that Exchange there shall be substituted the mean between the
lowest bid and the highest asked quotations in the over-the-counter market on
that day.

          (iv) If the Company shall distribute to the holders of its Common
Stock any evidences of its indebtedness, or any rights or warrants to subscribe
for any security other than its Common Stock, or any other assets (excluding
dividends and distributions in cash to the extent permitted by law), the
conversion rate in effect immediately prior to the record date fixed for the
determination of the holders of Common Stock entitled to such distribution
shall be increased, effective at the opening of business on the next following
full business day, to an amount determined by multiplying such conversion rate
by a fraction the numerator of which is the Current Market Price (as defined in
subparagraph 5(f)(iii), of the Company's Common Stock at said record date and
the denominator of which is such Current Market Price less the fair market value
(as determined by the Board of Directors, whose determination, in the absence of
fraud, shall be conclusive) of the amount of evidences of indebtedness, rights,
warrants or other assets (excluding cash dividends and

                                       5
<PAGE>
 
          distributions as aforesaid) so distributed which is applicable to one
          share of Common Stock. Notwithstanding the preceding sentence, if 
          such fair market value in the case of a particular distribution is
          less than Thirty-seven and One-half Cents ($0.375) in the case of
          $3.00 Preference Stock or One Dollar ($1.00) in the case of $2.80 
          Preference Stock, the increase in the conversion rate shall be 
          postponed and the amount of such fair market value shall be carried 
          forward and applied as provided in subparagraph 5(f)(v).

               (v) Whenever the amounts of Established Market Price and the
          amounts of fair market value being carried forward as provided in
          subparagraphs 5(f)(iii) and (iv) plus any similar amount determined in
          connection with a particular issue of rights or warrants or a
          particular distribution aggregate Thirty-seven and One-half Cents
          ($0.375) or more in the case of $3.00 Preference Stock or One Dollar
          ($1.00) in the case of $2.80 Preference Stock, the conversion rate in
          effect immediately prior to the record date fixed for the
          determination of the holders of Common Stock entitled to such
          particular issue or distribution shall be increased, effective at the
          opening of business on the next following full business day, by the
          aggregate of the increases in the conversion rate which were postponed
          as provided in subparagraphs 5(f)(iii) and (iv) plus the increase
          resulting from such particular issue or distribution.

               (vi) If the Company shall pay to the holders of its Common Stock
          a dividend in shares of Common Stock or if it shall split or combine
          the outstanding shares of its Common Stock, the amount of Thirty-seven
          and One-half Cents ($0.375) in the case of $3.00 Preference Stock and
          One Dollar ($1.00) in the case of $2.80 Preference Stock referred to
          in subparagraphs 5(f)(iii), (iv) and (v) (as theretofore decreased or
          increased) and also all amounts of Established Market Price and all
          amounts of fair market value then being carried forward as provided in
          subparagraphs 5(f)(iii) and (iv) (as theretofore decreased or
          increased) shall forthwith be proportionately decreased in the case of
          a stock dividend or split or increased in the case of a combination,
          so as to appropriately reflect the same, and all increases in the
          conversion rate then being postponed as provided in subparagraphs
          5(f)(iii) and (iv) (as theretofore increased or decreased) shall
          forthwith be proportionately increased in the case of a stock dividend
          or split or decreased in the case of a combination, so as to
          appropriately reflect the same.

          No adjustment of the conversion rate provided in subparagraph 5(a)
shall be made by reason of the issuance of Common Stock for cash except as
provided in subparagraph 5(f)(iii), or by reason of the issuance of Common Stock
for property or services. Whenever the conversion rate is adjusted pursuant to
this subparagraph 5(f) the Company shall (i) promptly place on file at the
office of each of its transfer agents for Preference Stock a statement signed by
the Chairman of the Board, the President or a Vice President of the Company and
by its Treasurer or an Assistant Treasurer or Secretary showing in detail the
facts requiring such adjustment and the conversion rate after such adjustment,
and shall make such statement available for inspection by shareholders of the
Company and (ii) cause a notice to be published at least once in a newspaper
printed in the English language and of general circulation in the Borough of
Manhattan, the City of New York, New York, stating that such adjustment has been
made and the adjusted conversion rate.

          (g) In case of any reclassification or change of the outstanding
shares of Common Stock of the Company (except a split or combination of shares)
or in case of any consolidation or merger to which the Company is a party
(except a merger in which the Company is the surviving corporation and which
does not result in any reclassification of or change in the outstanding Common
Stock of the Company except a split or combination of shares) or in case of any
sale or conveyance to another corporation of all or substantially all of the
property of the Company, effective provision shall be made by the Company or by
the successor or purchasing corporation

               (i) that the holder of each share of Preference Stock then
          outstanding shall thereafter have the right to convert such share into
          the kind and amount of stock and other securities and property
          receivable upon such reclassification, change, consolidation, merger,
          sale or conveyance by a holder of the number of shares of Common Stock
          of the Company into which such share of Preference Stock might have
          been converted immediately prior thereto, and

                                       6
<PAGE>
 
          (ii) that there shall be subsequent adjustments of the conversion rate
which shall be equivalent, as nearly as practicable, to the adjustments provided
for in subparagraph 5(f) above.

          The provisions of this subparagraph 5(g) shall similarly apply to
successive reclassifications, changes, consolidations, mergers, sales or
conveyances.

          (h) Shares of Common Stock issued on conversion of shares of
Preference Stock shall be issued as fully paid shares and shall be non-
assessable by the Company. The Company shall at all times reserve and keep
available, free from preemptive rights, for the purpose of effecting the
conversion of Preference Stock, such number of its duly authorized shares of
Common Stock as shall be sufficient to effect the conversion of all outstanding
shares of Preference Stock.

          (i) Shares of Preference Stock converted as provided herein shall
 not be reissued.

6. REDEMPTION AND ACQUISITION.

          The Company, at its option to be exercised by its Board of Directors,
may redeem the whole or any part of the Preference Stock or of any class thereof
or of any series thereof at any time at the applicable price for each share
which shall have been fixed and determined with respect thereto, plus an amount
equal to the accrued and unpaid dividends thereon computed to the date fixed for
redemption, whether or not earned or declared (hereinafter collectively called
the "redemption price"). If at any time less than all of the $3.00 Preference
Stock then outstanding is to be called for redemption, the Board may select one
or more series of $3.00 Preference Stock to be redeemed and if less than all of
the outstanding $3.00 Preference Stock of any series is to be called for
redemption, the shares to be redeemed may be selected by lot or by such other
equitable method as the Board in its discretion may determine. If at any time
less than all of the $2.80 Preference Stock then outstanding is to be called for
redemption, the shares to be redeemed may be selected by lot or by such other
equitable method as the Board in its discretion may determine. The Board may
determine that all shares of Preference Stock or all shares of either class of
Preference Stock or all shares of any series of $3.00 Preference Stock shall be
redeemed pro rata. Notice of every redemption, stating the redemption date, the
redemption price, and the place of payment thereof, and, if less than all of
either class of the Preference Stock then outstanding is called for redemption,
identifying the shares of such class of Preference Stock to be redeemed, shall
be published at least twice in a newspaper printed in the English language and
of general circulation in the Borough of Manhattan, the City of New York, New
York, the first publication to be not less than thirty (30) nor more than sixty
(60) days prior to the date fixed for redemption. Successive publications may be
made in the same or in a different newspaper or newspapers meeting the foregoing
requirements. Copies of such notice shall be mailed at least thirty (30) days
and not more than sixty (60) days prior to the date fixed for redemption to the
holders of record of the shares of Preference Stock to be redeemed at their
addresses as the same shall appear on the books of the Company, but failure to
give such additional notice by mail or any defect therein or failure of any
addressee to receive it shall not affect the validity of the proceedings for
redemption. The Company, upon publication of the first notice of redemption as
aforesaid or upon irrevocably authorizing the bank or trust company hereinafter
mentioned to publish or to complete publication of such notice as aforesaid, may
deposit or cause to be deposited in trust with a bank or trust company in the
City of New York, New York, an amount equal to the redemption price of the
shares to be redeemed, which amount shall be payable to the holders of the
shares to be redeemed upon surrender of certificates therefor on or after the
date fixed for redemption or prior thereto if so directed by the Board of
Directors of the Company. Upon such deposit, or if no such deposit is made then
from and after the date fixed for redemption unless the Company shall default in
making payment of the redemption price upon surrender of certificates as
aforesaid, the shares called for redemption or a pro rata part of each share in
cases of redemption pro rata shall cease to be outstanding and the holders
thereof shall cease to be stockholders with respect to such shares or pro rata
parts and shall have no interest in or claim against the Company with respect to
such shares or pro rata parts other than the right to receive the redemption
price from such bank or trust company or from the Company, as the case may be,
without interest thereon, upon surrender of certificates as aforesaid; provided
that conversion rights of shares called for redemption shall terminate at the
close of business on the fifth full business day prior to the date fixed for
redemption or at such later time as may be fixed by the Board of Directors of
the Company. Any funds so deposited which shall not be required for such
redemption because of the exercise of conversion rights

                                       7
<PAGE>
 
subsequent to the date of such deposit shall be returned to the Company. In case
any holder of shares of Preference Stock which have been called for redemption
shall not, within six (6) years after the date of such deposit, have claimed the
amount deposited with respect to the redemption thereof, such bank or trust
company, upon demand, shall pay over to the Company such unclaimed amount and
shall thereupon be relieved of all responsibility in respect thereof to such
holder, and thereafter such holder shall look only to the Company for payment
thereof. Any interest which may accrue on funds so deposited shall be paid to
the Company from time to time.

          The Company shall, subject to applicable law, have the right to
acquire Preference Stock from time to time at such price or prices as the
Company may determine, provided that unless dividends payable for all past
quarterly dividend periods on all outstanding shares of Preference Stock have
been paid, or declared and set apart for payment, in full, the Company shall not
acquire for value any shares of Preference Stock except in accordance with an
offer (which may vary as to terms offered with respect to shares of different
series but not with respect to shares of the same series) made in writing or by
publication (as determined by the Board of Directors) to all holders of record
of shares of Preference Stock.

          Preference Stock redeemed by the Company shall not be reissued and the
appropriate officers of the Company shall take appropriate action from time to
time to certify reductions in the number of shares of Preference Stock which the
Company is authorized to issue. Preference Stock acquired otherwise than upon
redemption or conversion shall not be cancelled or retired except by action of
the Board of Directors and shall have the status of treasury stock which may be
reissued by the Board until cancelled and retired by action of the Board.

7. ACTION BY COMPANY REQUIRING APPROVAL OF PREFERENCE STOCK.

          The Company shall not, without the affirmative vote at a meeting of
the holders of at least two-thirds of the then outstanding $3.00 Preference
Stock or of at least two-thirds of the then outstanding $2.80 Preference Stock:

          (a) change the preferences, qualifications, privileges, limitations,
     restrictions, or other special or relative rights granted to or imposed
     upon the shares of such class of Preference Stock in any material respect
     adverse to the holders thereof, provided that if any such change will
     affect any particular class or series of a class materially and adversely
     as contrasted with the effect thereof upon any other class or series of a
     class, no such change may be made without, in addition, such vote of the
     holders of at least two-thirds of the then outstanding shares of the
     particular class or series of a class which would be so affected; or

          (b) create or increase the authorized number of shares of any class of
     stock ranking as to dividends or assets prior to the class of Preference
     Stock;

and the Company shall not, without the affirmative vote at a meeting of the
holders of at least a majority of the then outstanding $3.00 Preference Stock of
all series and of at least a majority of the then outstanding $2.80 Preference
Stock;

          (c) create any class of stock ranking as to dividends or assets on a
     parity with the Preference Stock or increase the authorized number of
     shares of the Preference Stock or of any class of stock ranking as to
     dividends or assets on a parity with it; or

          (d) sell, lease or convey (which terms shall not include a mortgage)
     all or substantially all of the property or business of the Company; or

          (e) become a party to a merger or consolidation unless the surviving
     or resulting corporation will have immediately after such merger or
     consolidation no stock either authorized or outstanding (except such stock
     of the Company as may have been authorized or outstanding immediately
     before such merger or consolidation or such stock of the surviving or
     resulting corporation as may be issued upon conversion thereof or in
     exchange therefor) ranking as to dividends or assets prior to or on a
     parity with the Preference Stock or the stock of the surviving or resulting
     corporation issued upon conversion thereof or in exchange therefor.

8. VOTING RIGHTS.

     (a) Each holder of record of $3.00 Preference Stock shall have the right to

books of the Company. Each holder of record of $2.80 Preference Stock shall have
the right to two votes for each share of $2.80 Preference Stock standing in his
name on the books of the Company. In each election of directors in which holders
of Preference Stock are entitled to vote, every holder of Preference Stock
entitled to vote shall have the right to multiply the number of votes to which
he may be entitled by the total number of directors to be elected in the same
election by the holders of the class or classes or series of Preference Stock of
which his shares are a part, and he may cast the whole number of such votes for
one candidate or he may distribute them among any two or more candidates. If the
Company shall make a distribution to the holders of its Common Stock in the form
of a dividend in shares of Common Stock, or split the Common Stock, the vote to
which each holder of record of Preference Stock shall be entitled immediately
prior to the record date fixed for the determination of the holders of Common
Stock entitled to additional shares resulting from such dividend or split shall
be proportionately increased effective at the opening of business on the next
following full business day. Except as required by law or as otherwise
specifically provided in this Article IV of this Certificate the holders of
$3.00 Preference Stock, the holders of $2.80 Preference Stock and the holders of
Common Stock shall vote together as one class.

     (b) If the Company shall have failed to pay, or declare and set apart for
payment, dividends on all outstanding shares of $3.00 Preference Stock in an
amount equal to six quarterly dividends at the rates payable upon such shares,
the number of directors of the Company shall be increased by two at the first
annual meeting of the stockholders of the Company held thereafter, and at such
meeting and at each subsequent annual meeting until dividends payable for all
past quarterly dividend periods on all outstanding shares of each series of
$3.00 Preference Stock shall have been paid, or declared and set apart for
payment, in full, the holders of shares of $3.00 Preference Stock shall have the
right, voting as a class, to elect such two additional members of the Board of
Directors to hold office for a term of one year. Upon such payment, or such
declaration and setting apart for payment, in full, the terms of the two
additional directors so elected shall forthwith terminate, and the number of
directors of the Company shall be reduced by two, and such voting right of the
holders of shares of $3.00 Preference Stock shall cease, subject to increase in
the number of directors as aforesaid and to revesting of such voting right in
the event of each and every additional failure in the payment of dividends in an
amount equal to six quarterly dividends as aforesaid.

     (c) If the Company shall have failed to pay, or declare and set apart for
payment, dividends on all outstanding shares of $2.80 Preference Stock in an
amount equal to six quarterly dividends at the rate payable upon such shares,
the number of directors of the Company shall be increased by two at the first
annual meeting of the stockholders of the Company held thereafter, and at such
meeting and at each subsequent annual meeting until dividends payable for all
past quarterly dividend periods on all outstanding shares of $2.80 Preference
Stock shall have been paid, or declared and set apart for payment, in full, the
holders of shares of $2.80 Preference Stock shall have the right, voting as a
class, to elect such two additional members of the Board of Directors to hold
office for a term of one year. Upon such payment, or such declaration and
setting apart for payment, in full, the terms of the two additional directors so
elected shall forthwith terminate, and the number of directors of the Company
shall be reduced by two, and such voting right of the holders of shares of $2.80
Preference Stock shall cease, subject to increase in the number of directors as
aforesaid and to revesting of such voting right in the event of each and every
additional failure in the payment of dividends in an amount equal to six
quarterly dividends as aforesaid.

E. PREEMPTIVE RIGHTS

     1. Neither the holders of Preferred Stock, nor the holders of $3.00
Preference Stock, nor the holders of $2.80 Preference Stock, nor the holders of
Common Stock shall have preemptive rights, and the Company shall have the right
to issue and to sell to any person or persons any shares of its capital stock or

first offering such shares, rights or securities to any holders of the Preferred
Stock, the $3.00 Preference Stock, the $2.80 Preference Stock or the Common
Stock.


                                   ARTICLE V

                  ANNUAL AND SPECIAL MEETINGS OF STOCKHOLDERS

     A. Any action required or permitted to be taken by the holders of the
Capital Stock of the Company must be effected at a duly called annual or special
meeting of such holders and may not be effected by any consent in writing by
such holders. Except as otherwise required by law and subject to the rights of
the holders of any class or series of stock having a preference over the Common
Stock, special meetings of stockholders of the Company may be called only by the
Board of Directors pursuant to a resolution approved by a majority of the entire
Board of Directors or by the Chairman of the Board or by the President.

     B. Notwithstanding anything contained in this Certificate to the contrary,
the affirmative vote of at least 66 2/3% of all votes entitled to be cast by the
holders of Capital Stock entitled to vote generally in the election of directors
voting together as a single class shall be required to amend or repeal this
Article V or to adopt any provision inconsistent herewith.

                                   ARTICLE VI

                                   DIRECTORS

     A. Except as otherwise fixed by or pursuant to the provisions of Article IV
relating to the rights of the holders of any class or series of stock having a
preference over the Common Stock, the number of the directors of the Company
shall be fixed from time to time by or pursuant to the By-Laws of the Company.
The directors, other than those who may be elected by the holders of any class
or series of stock having a preference over the Common Stock, shall be
classified, with respect to the time for which they severally hold office, into
three classes, as nearly equal in number as reasonably possible, with the
directors in each class to hold office until their successors are elected and
qualified. Each member of the Board of Directors in the first class of
directors shall hold office until the Annual Meeting of Stockholders in 1986,
each member of the Board of Directors in the second class of directors shall
hold office until the Annual Meeting of Stockholders in 1987 and each member of
the Board of Directors in the third class of directors shall hold office until
the Annual Meeting of Stockholders in 1988. At each annual meeting of the
stockholders of the Company, the successors to the class of directors whose
terms expire at that meeting shall be elected to hold office for terms expiring
at the later of the annual meeting of stockholders held in the third year
following the year of their election or the election and qualification of the
successors to such class of directors.

     B. Subject to the rights of holders of any class or series of stock having
a preference over the Common Stock, nominations for the election of directors
may be made by the Board of Directors or by any record owner of Capital Stock of
the Company entitled to vote in the election of directors generally. However,
any such stockholder may nominate one or more persons for election as director
at a meeting only if written notice of such stockholder's intent to make such
nomination or nominations has been given, either by personal delivery or by
United States mail, postage prepaid, to the Secretary of the

                                       10
<PAGE>
 
Company not later than (i) with respect to an election to be held at an annual
meeting of stockholders, one hundred twenty (120) days in advance of such
meeting, and (ii) with respect to an election to be held at a special meeting of
stockholders for the election of directors, the close of business on the seventh
day following the earlier of (x) the date on which notice of such meeting is
first given to stockholders and (y) the date on which a public announcement of
such meeting is first made. Each such notice shall include: (a) the name and
address of each stockholder of record who intends to appear in person or by
proxy  to make the nomination and of the person or persons to be nominated; (b)
a description of all arrangements or understandings between the stockholder and
each nominee and any other person or persons (naming such person or persons)
pursuant to which the nomination or nominations are to be made by the
stockholder; (c) such other information regarding each nominee proposed by such
stockholder as would have been required to be included in a proxy statement
filed pursuant to the proxy rules of the Securities and Exchange Commission had
the nominee been nominated, or intended to be nominated, by the Board of
Directors; and (d) the consent of each nominee to serve as a director of the
Company if so elected. The chairman of the meeting may refuse to acknowledge the
nomination of any person not made in compliance with the foregoing procedure.

          C. Except as otherwise provided for, or fixed by, or pursuant to the
provisions of Article IV relating to the rights of the holders of any class or
series of stock having a preference over the Common Stock, newly created
directorships resulting from any increase in the number of directors or any
vacancy on the Board of Directors resulting from death, resignation,
disqualification, removal or other cause shall be filled solely by the
affirmative vote of a majority of the remaining directors then in office, even
though less than a quorum of the Board of Directors, or by a sole remaining
director. Any director elected in accordance with the preceding sentence shall
hold office for the remainder of the full term of the class of directors in
which the new directorship was created or the vacancy occurred and until such
director's successor shall have been elected and qualified. No decrease in the
number of directors constituting the Board of Directors shall shorten the term
of any incumbent director.

          D. Subject to the rights of holders of any class or series of stock
having a preference over the Common Stock, any one or more directors may be
removed only for cause by the stockholders as provided herein. At any annual
meeting of stockholders of the Company or at any special meeting of stockholders
of the Company, the notice of which shall state that the removal of a director
or directors is among the purposes of the meeting, the holders of Capital Stock
entitled to vote thereon, present in person or by proxy, by the affirmative vote
of at least 66 2/3% of all votes entitled to be cast by the holders of Capital
Stock of the Company entitled to vote generally in an election of directors
voting together as a single class, may remove such director or directors for
cause.

          E. The Board of Directors shall have the power to adopt, amend and
repeal By-Laws of the Company. Notwithstanding anything in this Certificate or
the By-Laws of the Company to the contrary (and notwithstanding that a lesser
percentage may be specified by law or in the By-Laws), the By-Laws shall not be
amended or repealed by vote of the stockholders of the Company and no provision
inconsistent therewith shall be adopted by vote of the stockholders of the
Company without the affirmative vote of at least 66 2/3% of all votes entitled
to be cast by the holders of Capital Stock of the Company entitled to vote
generally in the election of directors voting together as a single class.

          F. Notwithstanding anything contained in this Certificate to the
contrary, the affirmative vote of at least 66 2/3% of all votes entitled to be
cast by the holders of Capital Stock entitled to vote generally in the election
of directors, voting together as a single class, shall be required to amend or
repeal this Article VI or to adopt any provision inconsistent herewith.

                                  ARTICLE VII

                           PROHIBITION OF "GREENMAIL"

          A. Any purchase or other acquisition, directly or indirectly, in one
or more transactions, by the Company or any Subsidiary (as hereinafter defined)
of the Company of any share of Voting Stock (as hereinafter defined) or any
Voting Stock Right (as hereinafter defined) known by the Company to be
beneficially owned by any Interested Stockholder (as hereinafter defined) who
has beneficially owned such security or right for less than two years prior to
the date of such purchase shall, except as hereinafter expressly provided,

Delaware as the same exists or may hereafter be amended, a director of the

Law of Delaware, as so amended. Any repeal or modification of this Article IX by
the Stockholders of the Company shall not adversely affect any right or
protection of a director of the Company existing at the time of such repeal or
modification or with respect to events occurring prior to such time.

INDEMNIFICATION

     25.      (a) Right to Indemnification.  Each person who was or is a party
or is threatened to be made a party to or is involved or is threatened to be
involved (as a witness or otherwise) in or otherwise requires representation by
counsel in connection with any threatened, pending or completed action, suit or
proceeding, or any inquiry that such person in good faith believes might lead to
the institution of any such action, suit or proceeding, whether civil, criminal,
administrative or investigative (hereinafter a "proceeding"), by reason of the
fact that he or she is or was a director or officer of the Company or is or was
serving at the request of the Company as a director, officer, employee or agent
of another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to employee benefit plans, and the
basis of such proceeding is alleged action or inaction in an official capacity
or in any other capacity while serving as such a director, officer, employee or
agent, shall be indemnified and held harmless by the Company to the fullest
extent authorized by the General Corporation Law of Delaware, as the same exists
or may hereafter be amended (but, in the case of any such amendment with
reference to events occurring prior to the effective date thereof, only to the
extent that such amendment permits the Company to provide broader
indemnification rights than such law permitted the Company to provide prior to
such amendment), against all costs, charges, expenses, liabilities and losses
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and amounts paid in settlement) reasonably incurred or suffered by such person
in connection therewith and such indemnification shall continue as to a person
who has ceased to be a director or officer (or to serve another entity at the
request of the Company) and shall inure to the benefit of such person's heirs,
personal representatives and estate: provided, however, that, except as provided
in paragraph (b) hereof, the Company shall indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person against the Company only if such proceeding (or part thereof) was
authorized prior to its initiation by a majority of the disinterested members of
the Board of Directors of the Company. The rights to indemnification conferred
in this Section shall include the right to be paid by the Company any expenses
incurred in defending any such proceeding in advance of its final disposition;
provided, however, that, if the General Corporation Law of Delaware requires,
payment shall be made to or on behalf of such person only upon delivery to the
Company of an undertaking, by or on behalf of such person, to repay all amounts
so advanced if it shall ultimately be determined that such person is not
entitled to be indemnified under this Section or otherwise. The rights to
indemnification conferred in this Section shall be deemed to be a contract
between the Company and each person who serves in the capacities described above
at any time while this Section is in effect. Any repeal or modification of this
Section shall not in any way diminish any rights to indemnification of such
person or the obligations of the Company arising hereunder.

              (b) Right of claimant to bring suit. If a claim under paragraph
(a) of this Section is not paid in full by the Company within sixty days after a
written claim has been received by the Company, the claimant may at any time
thereafter bring suit against the Company to recover the unpaid amount of the
claim. If successful in whole or in part, the claimant shall be entitled to be
paid also the expense of prosecuting or defending such claim. In any action
brought by the claimant to enforce a right to indemnification hereunder or by
the Company to recover payments by the Company of expenses incurred by a
claimant in a proceeding in advance of its final disposition, the burden of
proving that the claimant is not entitled to be indemnified under this Section
or otherwise shall be on the Company. Neither the failure of the Company
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because the claimant has met the applicable standard of conduct set forth in the
General Corporation Law of Delaware, nor an actual determination by the Company
(including its Board of Directors, independent legal counsel, or its
stockholders) that the claimant has not met such applicable standard of conduct,

                                       4
<PAGE>
 
shall create a presumption that the claimant has not met the applicable standard
of conduct or, in the case of such an action brought by the claimant, be a
defense to the action.

     (c) Non-exclusivity of rights.  The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Section shall not be exclusive of any other right
which any person may have or hereafter acquire under any statute, the Company's
Certificate of Incorporation, any By-Law, any agreement, a vote of Company
stockholders or of disinterested Company directors, or otherwise, both as to
action in that person's official capacity and as to action in any other capacity
by holding such office, and shall continue after the person ceases to serve the
Company as a director or officer or to serve another entity at the request of
the Company.

     (d) Insurance.  The Company may maintain insurance, at its expense, to
protect itself and any director or officer of the Company or another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the Company would have the power to
indemnify such person against such expense, liability or loss under the General
Corporation Law of Delaware.

     (e) Indemnity agreements.  The Company may from time to time enter into
indemnity agreements with the persons who are members of its Board of Directors
and with such officers or other persons as the Board may designate, such
indemnity agreements to provide in substance that the Company will indemnify
such persons to the fullest extent of the provisions of this Section 25.

     (f) Indemnification of employees and agents of the Company.  The Company
may, under procedures authorized from time to time by the Board of Directors,
grant rights to indemnification, and to be paid by the Company the expenses
incurred in defending any proceeding in advance of its final disposition, to any
employee or agent of the Company to the fullest extent of the provisions of this
Section 25.

FISCAL YEAR AND ANNUAL REPORT

     26.      Fiscal year.  The fiscal year of the Company shall be the calendar
year.

     27.      Annual report.  The Board of Directors shall cause an annual
report to be prepared and mailed to the stockholders in accordance with the
rules and regulations of the Securities and Exchange Commission and the New York
Stock Exchange.

SHARE TRANSFERS AND RECORDS

     28.      Share transfers and records. The Board of Directors may appoint a
transfer agent or transfer agents and a registrar or registrars to make and
record all transfers of shares of stock of the Company or any class.

EMERGENCY BY-LAWS

     29.      When operative.  The emergency By-Laws provided by the following
sections shall be operative during any emergency resulting from an attack on the
United States, any nuclear disaster, earthquake or during the existence of any
catastrophe, as a result of which a quorum of the Board of Directors or the
Executive Committee thereof cannot be readily convened for action
notwithstanding any different provision in the preceding sections of the By-Laws
or in the Certificate of Incorporation of the Company or in the General
Corporation Law of the State of Delaware. To the extent not inconsistent with
the emergency By-Laws, the By-Laws provided in the preceding sections shall
remain in effect during such emergency and upon the termination of such
emergency, the emergency

By-Laws shall cease to be operative unless and until another such emergency
shall occur.

     30.      Meetings.  During any such emergency:

       (a) Any meeting of the Board of Directors may be called by any director.
     Whenever any officer of the Company who is not a director has reason to
     believe that no director is available to participate in a meeting, such
     officer may call a meeting to be held under the provisions of this section.

       (b) Notice of each meeting called under the provisions of this section
     shall be given by the person calling the meeting or at his request by any
     officer of the Company. The notice shall specify the time and the place of
     the meeting, which shall be the head office of the Company at the time if
     feasible and otherwise any other place specified in the notice. Notice need
     be given only to such of the directors as it may be feasible to reach at
     the time and may be given by such means as may be feasible at the time,
     including publication or radio.

     If given by mail, messenger, telephone or telegram, the notice shall be
     addressed to the director at his residence or business address or such
     other place as the person giving the notice shall deem suitable. In the
     case of meetings called by an officer who is not a director, notice shall
     also be given similarly, to the extent feasible, to the persons named on
     the list referred to in part (c) of this section. Notice shall be given at
     least two days before the meeting if feasible in the judgment of the person
     giving the notice and otherwise the meeting may be held on any shorter
     notice that he shall deem to be suitable.

       (c) At any meeting called under the provisions of this section, the
     director or directors present shall constitute a quorum for the transaction
     of business. If no director attends a meeting called by an officer who is
     not a director and if there are present at least three of the persons named
     on a numbered list of personnel approved by the Board of Directors before
     the emergency, those present (but not more than nine appearing highest in
     priority on such list) shall be deemed directors for such meeting and shall
     constitute a quorum for the transaction of business.

     31.      Lines of succession.  The Board of Directors, during as well as
before any such emergency, may provide, and from time to time modify, lines of
succession in the event that during such an emergency any or all officers or
agents of the Company shall for any reason be rendered incapable of discharging
their duties.

     32.      Offices.  The Board of Directors, during as well as before any
such emergency, may, effective during the emergency, change the head office or
designate several alternative head offices or regional offices, or authorize the
officers so to do.

     33.      Liability.  No officer, director or employee acting in accordance
with these emergency By-Laws shall be liable except for willful misconduct.

     34.      Repeal or change.  The emergency By-Laws shall be subject to
repeal or change by action of the Board of Directors or by the affirmative vote
of at least 66 2/3% of all votes entitled to be cast by the holders of Capital
Stock of the Company entitled to vote generally in the election of directors
voting together as a single class, except that no such repeal or change shall
modify the provisions of the next preceding section with regard to action or
inaction prior to the time of such repeal or change.

</TABLE> 

Divorced children are considered to be unmarried.

A child is considered to be living with you if the child lives in the same 
residence with you on a day-to-day basis unless away at school and not living 
with another parent.

Children ages 19 through 22 may work full or part-time, as long as the child 
is attending school on a regular basis and is dependent upon you for at least 
50% of support.  Eligible students through age 22 will be covered for up to 
six months after graduation while waiting to begin post-graduate studies.  
Also, if a medical condition prevents the child from attending school, the 
child is still eligible as long as the intention is to return to school.

The plan will cover your children to the extent required by a state Qualified 
Medical Child Support Order (QMCSO).  The plan secretary will notify you if 
the plan receives a QMCSO.  The plan secretary's office has prepared 
guidelines which are available through Executive Relations or the plan 
secretary's office.  It is recommended that proposed QMCSOs be reviewed by the
plan secretary's office for compliance with plan provisions and federal law.

  How to Enroll

You

To join the plan, you must return a completed enrollment form to Executive 
Relations within 31 days after your first day of work.  If you submit the 
enrollment form within 31 days of becoming eligible, coverage is effective the
later of:

  .the date Executive Relations receives the form;

  .your date of hire; or

  .the first day you're actively at work following your date of hire.

If you apply after the initial 31-day deadline, or if you withdraw from the 
plan and later reapply during open enrollment, coverage begins on the date 
Executive Relations receives the enrollment form.

If you're disabled and away from work when coverage would otherwise begin, 
your coverage begins as soon as you return to work.

If you transfer to an executive position from an employee group that isn't 
eligible for coverage under this plan, your Executive plan coverage 
automatically begins on the date of your transfer, and any coverage you had 
under any other Company-provided medical plan ends on that same date.

Once you're enrolled in the plan, Executive Relations will issue you an ID 
card.  Listed on the card are important telephone numbers you may need to 
call.

Your Dependents

You may obtain coverage for your dependents by electing family coverage when 
you join the plan.  You may be required to provide proof of dependent status.

If you apply for family coverage more than 31 days after your first day of 
work, coverage begins on the date Executive Relations receives the enrollment 
form.

If you're disabled and away from work when coverage would otherwise begin, 
your dependents' coverage begins as soon as you return to work.

If your dependent (other than a newborn) is confined to a hospital, medical 
facility or the home due to illness or injury when coverage would otherwise 
begin, coverage begins 31 days after the confinement ends.

  How to Change Coverage

When you start work at the Company, you choose the type of coverage -- single 
or family -- you wish to have.

Once your coverage begins, you need to inform Executive Relations if you wish 
to change from single to family coverage.  Information about changes in 
coverage is necessary so that we can adjust your coverage level and ensure 
prompt coverage when you add dependents.

When you report a change in coverage, your coverage will be adjusted as of the
date of the change or the date Executive Relations receives written notice of 
the change, whichever happens later.

You may discontinue your own or your dependents' coverage at any time.

  What Coverage Costs

The Company pays the full cost of the medical premiums for you and your 
eligible dependents.

  HOW THE PLAN WORKS

There are a number of terms you need to know in order to understand how the 
plan works.  The first time each of these terms is used, it will appear in 
boldface type and will be followed by its definition or a page reference 
indicating where that definition is located.  We've also included a glossary 
at the end of this SPD, which lists each term and shows you on which page its 
definition appears.

Medically Necessary/Reasonable and Customary

The plan pays 100% of covered expenses once Aetna Health Plans, the claims 
administrator, determines that the medical service or supply is medically 
necessary and the fees are reasonable and customary for benefit purposes.

Aetna considers charges for a treatment or service medically necessary if the 
treatment or service is required for the diagnosis and care of the medical 
problem, and commonly and customarily recognized as appropriate throughout the
medical profession.  The only exceptions are wellness services (see page 5), 
which may be covered whether or not they're associated with an illness or 
injury.

If you have any questions regarding Aetna's definition of "medically 
necessary", you should call the Customer Service number on your ID card before
obtaining the service or supply.

Fees that are reasonable and customary are within the range of fees usually 
charged by most doctors in their area for similar treatments or services.

Not only does the plan pay 100% for covered expenses, but you have no 
deductible to meet.  In other words, the plan pays all of your medical care...
provided the care is medically necessary and reasonable and customary.

Plan Maximums

There's no lifetime maximum benefit for most covered expenses.  However, for 
those medical services and supplies listed in the chart below, there's a 
maximum lifetime benefit of $2,000,000 for each covered person.

Covered Expenses

The plan covers most hospital and convalescent facility expenses, doctors' 
fees, and charges for other medical services and supplies, as follows.

"Wellness" services -- Performed by a doctor even though the service isn't 
related to a particular injury or illness, or considered medically necessary. 
The plan covers up to $250 of wellness expenses each year for each covered 
person and up to $750 for a family of three or more.  A partial list of covered
wellness services includes:

  .routine physical exams;

  .eye exams;

  .hearing exams;

  .well baby care;

  .immunizations;

  .cholesterol screenings;

  .routine mammograms;

  .routine pap smears (including the office visit); and

  .routine prostate exams.

Some services and supplies, such as chiropractic care, hearing aids, 
eyeglasses and prescription drugs, aren't covered under the wellness benefit.

To find out if a particular service or supply is covered under the wellness 
benefit, call the Customer Service number that appears on your ID card.

The following expenses are covered at 100% if they're medically necessary and 
reasonable and customary:

Inpatient hospital expenses -- Including:

  .room and board at a private room rate;

  .general nursing services provided by the staff;

       and the intensive care unit;
     - drugs and dressings provided by the hospital;
     - diagnostic X-ray and laboratory services;
     - radiation, radium and radioactive isotope therapy;
     - administration of anesthesia by an anesthesiologist;
     - administration of blood and blood plasma by a member of the hospital 
       staff;
     - physiotherapy and hydrotherapy; and


                                      5

      - professional ambulance service, when medically necessary, whether 
        charged by the hospital or an outside ambulance service, from the place
        of the illness/site of the accident to the nearest hospital;

   .consultation fees for services provided by a legally qualified doctor called
    in by the attending doctor while the patient is in the hospital.  This 
    coverage doesn't include: 
      - consultations involving hospital staff members; or
      - consultations that result in surgery performed by the consulting 
        doctor.  In this case, such fees are included in the charge for the 
        operation.

All hospital stays will be considered as having occurred during a single 
period of continuous disability unless you can provide acceptable evidence 
that:

  .you returned to active work for at least one full day between periods of 
   disability;

  .you or your dependent hasn't been hospitalized for at least 90 days;

  .the latest hospital stay isn't related to earlier hospital stays; or

  .although there were earlier hospital stays, you or your dependent has 
   completely recovered from the illness or injury which caused the earlier 
   hospital stay.

Outpatient hospital expenses -- Including:

  .treatment of illness or injury sustained in an accident or resulting from a
   medical emergency -- that is, a sudden and unexpected change in a person's
   physical condition requiring immediate care or treatment.  Without this 
   medical attention, the person's life could be in jeopardy or his/her 
   ability to function could be significantly impaired;

  .treatment of any non-surgical illness that isn't related to an accident or 
   a medical emergency;

  .hospital or freestanding ambulatory surgical facility charges in connection
   with a surgical procedure which are incurred on the same day the procedure 
   is performed;

  .freestanding birthing center services in connection with normal vaginal 
   deliveries only;

  .home intravenous therapy that follows a hospital stay.  The therapy must be
   recommended by a hospital, pharmacist or attending doctor to be considered a 
   covered expense.  Hospital charges for the necessary training of the 
   patient, family members or other persons responsible for administering the 
   intravenous medication are covered, but nutritional supplements aren't; and

  .diagnostic X-rays and laboratory services performed on an outpatient basis 
   within 14 days before or after admission to the hospital for the condition 
   that caused the hospitalization.

Surgery -- Services of qualified surgeons and assistant surgeons for procedures
performed in a hospital, a doctor's office or at your home.  A legally 
qualified dentist will be considered a "surgeon" when performing some of the 
oral surgery procedures listed below.  Also covered are charges for the 
related pre-operative and post-operative care given during the period of 
confinement in which the surgery is performed.  If more than one surgical 
procedure is being performed at one time, call Aetna in advance of the surgery
to determine how the reimbursement may be affected by these multiple 
procedures.

                                      6
<PAGE>
 
If you or a covered dependent requires non-emergency surgery, you may request 
that your doctor provide Aetna with an estimate of surgical expenses.  This 
estimate allows Aetna to determine in advance whether or not the proposed 
charges meet the reasonable and customary guidelines.

For details, call the Customer Service number that appears on your ID card.

The plan covers most surgical procedures.  Listed below are some procedures 
about which questions are most frequently asked:

  .circumcision;

  .cosmetic surgery necessary for the prompt repair of an injury resulting 
   from an accident;

  .obstetrical care.  You should file a claim for prenatal care, delivery and 
   post-natal care at the time of delivery.  If this isn't possible, you need 
   to call the Customer Service number that appears on your ID card;

  .oral surgery for the following procedures only:
      - the excision of partially or completely unerupted, impacted teeth;
      - apicoectomy, which is the excision of a tooth root without the 
        extraction of the entire tooth.  However, root canal therapy isn't 
        covered.
      - the closed or open reduction of fractures or dislocations of the jaw;
      - the prompt repair of natural teeth or dental tissue damaged in an 
        accident;
      - other incision or excision procedures on the gums and tissues of the 
        mouth when not performed in connection with tooth repair or 
        extraction.  Keep in mind that dental cleaning, root scaling, planing 
        or other scraping procedures aren't covered; and
      - alteration of the jaw, jaw joints or bite relationships by a cutting 
        procedure when appliance therapy alone cannot result in functional 
        improvement;
  
  .vasectomies and tubal ligations (lawfully performed voluntary sterilization
   operations).  Hospital expenses won't be covered for routine vasectomies, 
   since these usually can be performed in the doctor's office. 

Voluntary secondary opinions -- A voluntary second opinion is a voluntary 
consultation with a physician other than the first physician who recommended
and proposed to perform a surgery.

Emergency care and treatment -- Provided by a doctor in the doctor's office, a
hospital outpatient department or emergency room, or at home following an 
accident or a medical emergency. 

Inpatient doctor's care and treatment -- Provided by a doctor or psychiatrist 
in a hospital or convalescent facility if the patient is ill or injured and 
confined as a bed patient.

Outpatient doctor's care and treatment -- Provided in the doctor's office or 
at home for any illness.

Prescription drugs -- Drugs and medications which can be obtained only with a 
doctor's prescription.  Certain other drugs and medications which normally 
don't require a prescription may be covered if ordered by your doctor on 
his/her prescription forms.

The plan offers you three alternatives for paying for prescription drugs.

Standard Drug Coverage

You may have your prescriptions filled at any pharmacy you choose.  Simply pay 
the full cost of the prescription and then file a claim with Aetna for reim-
bursement.  Your covered prescriptions will be reimbursed at 100%.

Aetna Pharmacy Management

The Aetna Pharmacy Management (APM) program involves a network of pharmacies 
that have agreed to provide discounted prices to plan members for short-term
prescription drug supplies (30 days or less).  Major pharmacy chains, as well as
numerous independents, participate in the APM program nationwide.  Your Aetna
claim office can provide you with a list.

APM is also a partnership -- one from which plan members, ARCO and participating
pharmacies can all benefit.  By offering discount rates, network pharmacies 
attract more customers and increase their business volume.  ARCO saves money by 
taking advantage of the participating pharmacies' lower, preferred rates, which
in turn controls the Company's overall expenditure for medical insurance.

APM network pharmacies automatically fill your prescriptions with approved 
generic drugs, unless you or your doctor specifies otherwise on your 
prescription.  Generic drugs have the same ingredients as brand-name drugs but 
are less expensive.

The APM program is easy to use.  Take your prescription to a participating 
pharmacy and present your Aetna ID card.  The full discounted cost of the 
prescription will be reimbursed directly to the pharmacy by the plan.  You pay 
nothing and there are no claims to file.

If you're interested in finding out more about the APM program, contact 
Executive Relations or your claim office.

Express Pharmacy Services

If you or one of your covered dependents relies on prescription drugs for the 
treatment of long-term or chronic conditions, such as diabetes, arthritis or 
heart disease, ARCO can offer you another alternative:  the mail order 
prescription drug program, which is administered by Express Pharmacy Services of
the Thrift Drug Company (a division of J.C. Penney).  As under the APM program, 
your prescriptions will automatically be filled with approved generic drugs, 
unless you or your doctor specifies otherwise on your prescription.

                                       8
<PAGE>
 
When you order prescription drugs through Express Pharmacy Services, the plan
pays 100% of the cost of each prescription. The program saves you the time of
waiting at a drug store, since prescriptions are delivered to your home within
14 days of your order. In addition, you pay nothing and there are no claim forms
to file.

Prescription drugs not covered by the plan, such as oral contraceptives and
minoxidil, may be ordered through the mail order program. Though you will pay
the entire cost of the prescription, you will be able to take advantage of the
mail order discounted prices. Selected non-prescription vitamins are also
available.

If you're interested in finding out more about Express Pharmacy Services,
contact Executive Relations.

The chart on page 8 shows you how your prescription drug services work together.
With a little thought and planning, you can use these programs to your
advantage.

Diagnostic X-ray and laboratory services -- Relating to an illness or injury and
performed while the patient isn't confined in a hospital. If these tests are
performed while the patient is hospitalized, the charges are considered
miscellaneous hospital expenses. Fees for the doctor interpreting the findings
are also covered.

Radiation, radium and radioactive isotope therapy -- Relating to an illness or
injury and performed while the patient isn't confined in a hospital.

Non-surgical cosmetic expenses -- Incurred in connection with cosmetic surgery
required for the prompt repair of an injury resulting from an accident.

Spinal manipulation and modalities -- And other related services, including
cervical manipulation and modalities. The services include office visits, 
X-rays, examinations, consultations, and spinal and cervical manipulations
directly related to the treatment of an injury. Services may be performed by
doctors, chiropractors, osteopaths and other providers, but doesn't apply to
services provided if you're hospitalized. Maintenance therapy isn't covered
under the plan.

Physical, occupational and speech therapy prescribed by a doctor -- For
treatment of an illness or injury while not confined in a hospital, if
determined to be medically necessary by Aetna.

Prosthetic devices -- Including:

  .artificial limbs;
   
  .the first external breast prosthesis, the first brassiere designed
   exclusively for use with the prosthesis or the cost of an internal breast
   prosthesis made necessary by a mastectomy;
   
  .the first set of contact lenses and/or eyeglasses made necessary by cataract
   surgery, if purchased within one year after the surgery; and
   
  .the first hearing aid purchased after inner-ear surgery or to correct an
   impairment directly caused by an accident. To be a covered expense, the
   device must be purchased within one year after the accident or surgery.
   Because eyeglass-type hearing aids are elective, covered expenses for such
   items are limited to the cost of hearing aids that have a standard design.

The plan covers the repair of prosthetic devices when it's less expensive than
the cost of replacement. However, the plan will cover the replacement of
prosthetic devices when:

  .the existing device cannot be repaired; or 

  .the replacement is recommended by your doctor because of a change in your
   physical condition.

                                      9
<PAGE>
 
Rental or purchase of special durable medical supplies and equipment -- Such as
hospital beds, wheelchairs and crutches.

To find out if a particular supply or piece of equipment is covered under the
plan, you should request prior authorization from Aetna.

Private duty nursing -- If medically necessary and ordered by your doctor and
performed by a registered nurse who isn't a member of your family or your
spouse's family.

To find out if a benefit will be paid, you should request prior authorization
from Aetna before engaging a private duty nurse.

Convalescent Care -- At a facility that provides skilled nursing care. Coverage
includes room and board at a private room rate and miscellaneous charges for
medical supplies and services, such as medication, dressings and physiotherapy
provided by the facility. The patient must be under the continuous care of a
doctor.

To be covered, the confinement:

  .must be medically necessary as determined by Aetna;
   
  .must begin within 14 days of a hospital stay that lasts at least three
   consecutive days; and
   
  .must be for care in connection with the same illness or injury which caused
   the hospital stay.

The plan does not cover:

  .custodial care;
   
  .convalescent care for chronic psychiatric conditions or drug addiction; or
   
  .care that can't reasonably be expected to lessen the degree of the patient's
   disability and enable the patient to live outside an institution.

Home health care -- Skilled nursing services determined by Aetna to be medically
necessary and provided at home.  The plan covers:

  .part-time or intermittent nursing care by a registered nurse or licensed
   practical nurse. A care provider cannot be a member of your family or your
   spouse's family;
   
  .part-time or intermittent home health aide services supervised by a
   registered nurse, consisting primarily of caring for the patient;
   
  .medical supplies and laboratory services, but only if they would have been 
   covered had the patient remained in a hospital or an extended care facility;
   
  .medicines and drugs prescribed by a doctor; and 
   
  .physical, occupational and speech therapy.

Your doctor must submit a written home health care plan to Aetna certifying that
without home health care, the patient would have to be hospitalized or confined
in a convalescent facility.  Benefits are payable only if Aetna pre-approves the
home health care plan.

Coverage is limited to 120 home health care visits, up to four hours for each 
visit, per covered person per year.

The plan does not cover:

  .the services of a member of the patient's family or a person who normally 
   lives with the patient;
   
  .any period when the patient isn't under the continuing care of a doctor;

                                      10
<PAGE>
 
  .care or treatment not specified in the home health care plan submitted by 
   your doctor and approved by Aetna;

  .transportation services; or

  .custodial care.

Hospice care -- Through an accredited facility or agency offering care 
designed to meet the physical, psychological and social needs of terminally 
ill patients and their families.

Covered expenses for inpatient hospice care include room and board at a 
private room rate, fees for hospice care and doctors' services, and 
miscellaneous charges for services and supplies provided by the hospice.

Outpatient hospice care must be provided by an accredited hospice care agency 
that offers around-the-clock skilled nursing services, medical social services
and psychological counseling.

Your doctor and the appropriate hospice personnel must provide Aetna with a 
written care plan that assesses the patient's medical and social needs and 
describes the care required to meet those needs. The plan must be reviewed 
periodically by your doctor and the appropriate hospice personnel for plan 
coverage to continue. 

The plan does not cover:

  .charges for services provided by a homemaker or caretaker;

  .bereavement, pastoral, financial or legal counseling; or

  .funeral arrangements.

Treatment of psychiatric conditions

  .Inpatient hospital The plan covers:
   ------------------
      - hospital services and supplies (see page 5);
      - doctors' charges for as long as medically necessary, but only if a
        comprehensive treatment program, including after-care, is prescribed and
        supervised by a legally qualified doctor; and
      - charges for family consultations (that is, conjoint therapy) when 
        necessary while the person requiring treatment is hospitalized.
      
  .Outpatient care (non-hospital) If treatment is received on an outpatient
   ----------------------------
    basis, the plan covers charges for care provided by a legally qualified
    doctor plus drugs prescribed for the treatment of the condition. Care
    provided for non-medical conditions, such as marriage counseling, isn't
    covered.

Treatment by a licensed psychologist or licensed clinical social worker (LCSW)
is covered on the same basis as psychiatric care by a doctor if it's required 
for the diagnosis or treatment of a psychiatric condition under the plan. If a
licensed marriage, family and child counselor (MFCC) provides the necessary 
care, those charges will be considered if the counselor has been referred by a
psychiatrist, licensed psychologist or medical doctor.

In states where an LCSW or MFCC license isn't available, Aetna will consider 
charges from a therapist holding an equivalent license on the same basis as 
described above if the therapist has an accredited master's degree or higher, 
is in clinical practice, has had at least two years of supervised experience, 
and is under the direct supervision of a psychiatrist, licensed psychologist 
or physician.

                                     11

Treatment of alcoholism and drug addiction

  . Inpatient hospital The plan covers:
    ------------------
      - hospital services and supplies (see page 5);
      - doctors' charges for as long as medically necessary, but only if a 
        comprehensive treatment program, including after-care, is prescribed
        and supervised by a legally qualified doctor; and
      - charges for family consultations (that is, conjoint therapy) when 
        necessary while the person requiring treatment is hospitalized.

  .Non-Hospital Treatment Center The plan pays a benefit only if treatment is
   -----------------------------

   Center or Hazelden. To find out if a facility is Aetna-approved, call the
   Customer Service number that appears on your ID card.
   
      Once the facility and plan of treatment are approved, the plan covers:
      - facility services and supplies for 30 days;
      - doctors' charges directly related to the treatment program; and
      - charges for conjoint therapy during the confinement.

      90 days.
   
  .Outpatient care (non-hospital) If treatment is received on an outpatient 
   ------------------------------
   basis, the plan covers charges for care provided by a legally qualified
   doctor or licensed psychologist, plus drugs prescribed for the treatment
   of the condition.

Expenses Not Covered

The plan won't pay for medical services and supplies which:

  .are not considered medically necessary (see page 4). This applies even if 
   the diagnosis, care or treatment is prescribed, recommended or approved by 
   your doctor or dentist;
   
  .exceed reasonable and customary charges (see page 4);
   
  .exceed the plan's maximum benefits (see page 4);
   
  .exceed the wellness benefit of $250 per person and $750 per family;

   terms of generally accepted medical standards or still under clinical
   investigation by medical professionals. This exclusion does not apply to
   care, treatment, services or supplies (other than drugs) received in
   connection with a disease if Aetna determines that:
      - in the absence of effective treatment, the disease can be expected to 
        cause death within one year; and
      - scientific data indicate that the care or treatment is effective for
        that disease or shows promise of being effective for that disease. In
        making this determination, Aetna will take into account the results of
        a review by a panel of independent medical professionals, selected by
        Aetna, including professionals who treat the type of disease involved;

  .the following types of treatment for psychiatric conditions:
      - primal therapy
      - rolfing

   impaction or surgery not connected with the extraction or repair of teeth;

  .the purchase and fitting of hearing aids, except to correct an impairment 
   directly caused by an accident or if needed after inner-ear surgery and 
   purchased within one year after the surgery;

  .cosmetic surgery, unless prompt repair is needed to correct damage caused 
   by an accident;

  .treatment of obesity or for diet or weight control, unless approved by 
   Aetna;

  .acupuncture therapy. This exclusion does not apply to acupuncture 
   performed by a covered health care provider as a form of anesthesia in 
   connection with surgery that's covered under the plan;

  .services or supplies related to organ or tissue transplants. This 
   exclusion does not apply to charges made to a covered person who either

      - kidney
      - cornea
      - bone marrow*

  .services of a doctor, physical therapist, occupational therapist, speech
   therapist or audiologist provided to covered children who are physically or
   mentally impaired or learning disabled.

The preceding list of the plan's exclusions and limitations may not be complete.
If you have questions about coverage for a specific medical expense, call the
Customer Service number that appears on your ID card.

Coordination of Benefits

Coordinating with Other Plans

The plan has been designed to help you meet the cost of illness or injury. It's
not intended that your reimbursement ever exceed your actual medical expenses.
As a result, the plan coordinates the benefits it pays by taking into account
any coverage you or your covered dependents may have under any other group plans
or government programs or coverage provided by law. (A group plan provides
benefits or services for medical or dental care or treatment.)

Here's how coordination of benefits works. When you receive medical care that's
also covered under another plan, one of the plans is the primary plan, and the
other plan is the secondary plan. If the Executive plan is primary, it pays its
benefits first. If the Executive plan is secondary, it adjusts its benefits so
that the total amount of benefits you receive isn't more than 100% of your
allowable expenses. These expenses are defined as reasonable and customary
charges payable under the plan.

A plan with no provision for coordination with other benefit plans becomes the 
primary plan and pays its benefits first.

See page 15 for a look at how a benefit is paid if all plans coordinate
payments.

In addition, if you're covered as an active employee under one plan and as a
retiree under another plan, the plan covering you as an active employee pays
first, and the plan covering you as a retiree (or as an inactive employee) pays
second. If none of the rules above apply, the plan under which you've been
covered for the longest period of time pays first.

Coordinating with Medicare

You should contact your local Social Security office for details about Medicare 
enrollment as soon as you or your dependent begins to receive Social Security 
disability payments or at least three months before you or your spouse reaches 
age 65.

Totally Disabled and Not Retired

If you're totally disabled, you may be eligible for Medicare. If you choose to
be covered under both the Executive plan and Medicare, the Executive plan is the
primary plan, and Medicare is the secondary plan.

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

From the time you become eligible for Medicare, you
may choose to have your medical coverage provided
through:

  .the Executive plan only;
   
  .the Executive plan supplemented by Medicare; or
   
  .Medicare only.

If you choose primary coverage under Medicare,
Medicare pays its usual benefit, the Executive plan
doesn't pay benefits -- and you're responsible for any
additional costs. You'll need to contact Executive
Relations if you choose to be covered under Medicare.

Age 65 and Still Working

Government regulations require that ARCO offer you a
choice of medical plans if you continue working past
age 65.

From age 65 on, you may choose to have your medical 
coverage provided through:

  .the Executive plan only;
   
  .the Executive plan supplemented by Medicare; or
   
  .Medicare only.

                                      15
<PAGE>
 
If you chose to be covered under both the Executive plan and Medicare, the
Executive plan is the primary plan -- since you're an active employee -- and
Medicare is the secondary plan.

If you chose coverage under Medicare only, Medicare pays its usual benefit, the
Executive plan doesn't pay benefits -- and you're responsible for any additional
costs. You'll need to contact Executive Relations if you choose to be covered
under Medicare.

At Age 65 (or Totally Disabled) and Retired

Once you or your covered dependent is eligible for Medicare, you need to notify
ARCO's Benefit Plans Administration-Insurance Unit at 74 N. Pasadena Avenue,
Pasadena, California 91103, so that your medical coverage election can be
adjusted.  You'll need to provide proof of Medicare eligibility.

After you become Medicare-eligible, Medicare becomes the primary plan and the 
Executive plan becomes the secondary plan for purposes of coordinating benefits.

If you're covered under the Executive plan and don't apply for Medicare even 
though you're eligible to do so, the Executive plan coordinates benefits as if 
you were covered under Medicare.


How To File a Claim

The plan is designed to help process your claim as quickly as possible.  You or 
the provider of services should send claims directly to the Aetna claim office 
indicated on your ID card.  Claim forms and instructions for their completion 
are available from your Aetna claim office or Executive Relations.

A fully completed claim form must be returned to Aetna for each covered family 
that incurs medical expenses.

All family members may be listed on the same claim form.  This form should be 
sent:

  .once every 12 months; or

  .when a family member experiences one of the changes listed on the bottom 
   portion of the claim form which requires claim office notification.

For prompt payment of your claim, you must include the following information 
with your claim form:

  .the provider's name;

  .the date of treatment; and 

  .itemized bills for services performed by the provider. If you have standard
   drug coverage, a bill from the pharmacist must always identify the
   prescription dispense diagnosis, the purchase date, the person to whom the
   prescription is issued and the doctor who issued it.

You don't need to attach a claim form with each additional claim you file.  Just
be sure that the patient's name and your Social Security Number appear on the 
bill.

Additional claims may be filed as expenses are incurred, and claims for more 
than one covered person may be sent at the same time.

You must file your claim within two years after the expense was incurred.
Otherwise, covered expenses won't be paid. If you participate in the Health Care
Account and wish to file claim for eligible medical expense, you must do so by
March 31 of the year following the year that the expenses was incurred, subject
to the Health Care Account claim filing instructions included in your Health
Care Account summary plan description.

                                      16
<PAGE>
 
Doctor's Services

After receiving the claim, Aetna will screen it for completeness, verify 
eligibility and determine if the expense is covered under the plan. If Aetna 
needs more information to make a benefit determination, you or your doctor 
will be asked to provide Aetna with that information.

Payments will be made directly to you unless you've:

  .signed the section of the claim form authorizing Aetna to pay the doctor 
   directly; or

  .executed an assignment of benefits to the provider, which is kept on file 
   in the doctor's office.

Hospitalization

Generally, to receive benefits under the plan, you need only present your ID 
card to the provider, who in turn will submit all necessary claim information 
to Aetna. Providers include hospitals, convalescent facilities or other health
care institutions that have been recognized and approved by Aetna. When 
services are provided in hospitals in foreign countries, you may be required 
to send benefit claims directly to Aetna.

After receiving the claim, Aetna will screen it for completeness, verify 
eligibility and determine if the expense is covered under the plan. If Aetna 
needs more information to make a benefit determination, you or the hospital 
will be asked to provide Aetna with that information.

Aetna will pay the provider directly. However, if you've paid the hospital and
the hospital has marked the bill "paid in full," payment will be made to you.

How to File an Appeal

Claim Denial

If you file a benefit claim that is partially or wholly denied, you'll receive
written notice of the denial within 90 days after Aetna receives the claim. 
This time limit may be extended for an additional 90 days in special cases, 
but you'll be notified of the reasons for the delay. In no event will this 
extension exceed 90 days.

The denial notice will explain the reasons for the denial, state the plan 
provisions on which the denial is based, describe any additional information 
or material required and discuss the procedures you must follow if you want a 
further review of your claim.

Claim Review

If your benefit claim is partially or wholly denied, you may contact your 
Aetna claim office within 60 days after receiving the denial notice and 
request a claim review. When you do, you need to provide:

  .the name(s) and address(es) of both patient and employee;

  .the employee's Social Security Number;

  .the date service or treatment was received;

  .the provider's name (doctor, hospital, etc.); and

  .the reason you think the claim should be reviewed.

In addition, you or a designated authorized representative may review 
pertinent documents and submit additional issues in writing.

                                     17
<PAGE>
 
Within 60 days (or 120 days in some cases) after you file your request, Aetna 
will notify you in writing of its final decision, including the specific 
reasons for its determination.

If Aetna finally denies the claim because of the patient's ineligibility to
participate in the plan or other issues unrelated to the payment of claims, you
may request that ARCO's Welfare Plans Administrative Committee review the claim.
Contact Executive Relations for information on how to file this type of appeal.

  When Coverage Ends

You

Except as discussed under COBRA (see page 19), your coverage under the plan 
ends on whichever of the following happens first:

  .the last day of the month in which you're no longer an active executive;

  .the last day of the month in which you're granted a formal unpaid leave of
   absence which doesn't allow for continuation of medical coverage; or

  .the date the plan is terminated.

Your Dependents

Coverage for your eligible dependents terminates the last day of the month in 
whichever of the following happens first:

  .your coverage ends for any reason (including your death); or

  .your dependents become ineligible.

If you die while covered under the plan, coverage for your eligible dependents
will continue until the end of the month in which you die. Their coverage will
then be transferred to the Atlantic Richfield Comprehensive Medical Plan, and 
the Company will continue to pay the full premiums.

This option is available only if your spouse or dependents waive COBRA 
continuation coverage (see page 19). For more information, contact Executive 
Relations.

  How To Continue Coverage

On a Leave of Absence 

If you're granted a leave of absence, your right to continue medical coverage 
during the leave depends on the provisions of the leave you've taken.

For more details on medical coverage during leaves of absence, contact 
Executive Relations.

For Disabling Conditions Only

If you or one of your covered dependents is totally disabled, as determined by
Aetna, when your medical coverage ends, any medical expenses related to the 
illness or injury that caused the disability are covered until whichever of 
the following happens first:

  .one year after coverage for you or your dependent would otherwise end;

  .the person with the disability is covered by another group plan that offers
   similar benefits; or

  .the person is no longer totally disabled.

                                     18
<PAGE>
 
You're considered totally disabled under this plan if, as the result of 
illness or injury:

  .you can't perform the regular duties of a job for which you're reasonably 
   qualified because of your education, training or experience; and

  .you're not performing any work of any kind for pay or profit.

Your dependents are considered totally disabled if illness or injury prevents
them from engaging in the normal activities of a healthy person of similar 
age.

All extended benefits are subject to this plan's provisions and are limited 
to the treatment of the disabling condition only.

At Retirement

As a retiree, you may be able to continue your medical coverage if, at the 
time of your retirement, the Company offers retiree coverage and you don't 
elect COBRA continuation coverage.

To be eligible for retiree coverage, you must be enrolled in this plan when 
you retire and, while you're a plan member, you:

  .leave the Company once you reach age 62;

  .leave the Company at any time that you're eligible for an immediate 
   retirement allowance from a qualified retirement plan; or

  .leave the Company and are eligible for retiree coverage under the Company's
   special termination policy

Understanding COBRA Coverage

As required by the Consolidated Omnibus Budget Reconciliation Act of 1985 
(COBRA), you and your covered dependents have the option to continue your 
medical coverage for a specified time when such coverage would otherwise end.

To continue coverage due to divorce or loss of dependent status, you or a 
family member must inform Executive Relations within 60 days of the  
occurrence of either of these events.

Who Qualifies

You

You may continue your coverage in this plan or the Atlantic Richfield 
Comprehensive Medical Plan for up to 18 months if you would otherwise lose 
coverage because:

  .your hours of work are reduced;

  .you're laid off; or

  .you leave the Company for reasons other than gross misconduct.

If you elect COBRA coverage under the Atlantic Richfield Comprehensive Medical
Plan, you cannot change your coverage to the Atlantic Richfield Executive 
Medical Plan during a subsequent open enrollment.

If you leave the Company under a special termination policy that offers 
Company-provided medical coverage under the Executive plan, you may choose to be
covered under either the terms of the special termination policy or COBRA
coverage as described here.

                                     19 






<PAGE>
 
The cost of COBRA coverage equals 102% of the plan's premiums. You'll be 
informed of the cost of COBRA coverage when you apply.

Your Spouse

If your spouse is covered under the plan, he/she may continue coverage for 
himself/herself for up to 18 months under the circumstances described under 
"Who Qualifies -- You" (see page 19).

Your spouse may continue coverage for up to 36 months if coverage would 
otherwise end because:

  .you die; or

  .you and your spouse divorce.

If your spouse elects COBRA coverage under the Atlantic Richfield 
Comprehensive Medical Plan, he/she cannot change coverage to the Executive 
Medical Plan during a subsequent open enrollment.

At your death, your spouse may choose either COBRA coverage or survivor 
coverage under the terms of the ARCO Comprehensive Medical Plan covering your 
spouse at that time.

The cost of spouse COBRA coverage equals 102% of the plan's premiums. Your 
spouse will be informed of the cost of COBRA coverage when he/she applies.

Your Dependent Children

If your dependent children are covered under the plan, they may continue 
coverage for up to 18 months under the circumstances described under "Who 
Qualifies -- You'' (see page 19).

Your covered children may continue coverage for up to 36 months if their 
coverage would otherwise end because:

  .you die;

  .you and your spouse divorce; or

  .your covered children lose their dependent status under the plan.

If your dependent children elect COBRA coverage under the Atlantic Richfield 
Comprehensive Medical Plan, they cannot change coverage to the Executive 
Medical Plan during a subsequent open enrollment.

The cost of COBRA coverage for dependent children equals 102% of the plan's 
premiums. Your covered children will be informed of the cost of COBRA coverage
when they apply.

When COBRA Coverage is Extended

Disability Continuation Coverage

An 18-month COBRA continuation period may be extended to a total of 29 months 
if:

  .you or your dependent is considered totally disabled under Social Security 
   rules when coverage first begins; and

  .the disability continues throughout the COBRA coverage period.

However, this coverage applies only to the person with the disability and not 
to any other dependents.

                                     20
<PAGE>
 
To qualify for the additional 11 months of COBRA coverage, you or your 
dependent must notify Executive Relations:

  .within 60 days of being classified as totally disabled under Social 
   Security; and

  .during the original 18-month COBRA continuation period.

You may be asked to provide proof of the disabling condition.

Likewise, if Social Security determines that you or your dependent is no 
longer totally disabled, you must notify Executive Relations within 31 days.

The cost for the additional 11 months of disability continuation coverage 
equals 150% of the cost of the plan's premiums. You or your dependent will be 
notified of the exact cost when you or your dependent applies.

Additional Events

If one of the events listed on pages 19 & 20 occurs while you, your spouse or 
your dependents are covered during the 18-month COBRA continuation period, 
coverage will be considered to have begun on the date of the first event and 
may be extended for up to 36 months after that date.

When COBRA Coverage Ends

COBRA coverage ends if:

  .you or your covered dependent fails to pay the required premiums;

  .you or your covered dependent becomes covered under another group plan that
   includes coverage for preexisting conditions for which coverage is provided 
   under the Executive plan;

  .you or your covered dependent becomes eligible for Medicare; or

  .all ARCO medical plans are terminated.

New laws and regulations may change any of the COBRA information presented 
above. Also, you and your dependents may have to satisfy certain notice
requirements in order to receive COBRA coverage. For more details on how you 
can obtain COBRA coverage under the plan, contact Executive Relations.

When the Plan Ends

The Company expects and intends to continue the plan indefinitely, but 
reserves the right to amend or terminate it at any time.

If the plan is terminated, your coverage will end on the plan's termination 
date. However, if you or one of your dependents is totally disabled at the 
time, benefits will continue to be available as described on page 18. All 
extended benefits are subject to the plan's provisions and limitations.

How To Convert Your Coverage

You or your covered dependents may apply for an individual insurance policy 
from Aetna if coverage ends. If you're interested in this coverage, contact 
Executive Relations.

Since an individual policy isn't a continuation of coverage under the plan, 
the benefits that will be provided and the cost of the policy won't be the 
same as provided under this plan, but will be determined by Aetna.

                   YOUR LIFE INSURANCE BENEFITS--AN OVERVIEW

ARCO's life insurance plan and accidental death and dismemberment (AD&D)
coverage offer important financial security for you and your family in the event
of injury or death.

The Executive Life Insurance Plan includes three components:

      . basic life coverage, which pays the first $50,000 of your life insurance
        benefit, as well as an additional benefit if your death or dismemberment
        is caused by an accident. This coverage also provides some insurance on
        the lives of your spouse and each of your children;

      . executive life coverage, which provides insurance on your life only and
        pays a benefit equal to three times your annual base pay, less the
        $50,000 benefit provided by basic life coverage. Executive life coverage
        also lets you choose the form of survivor payments which best meet your
        beneficiaries' needs; and

      . optional life coverage, which gives you the opportunity to purchase
        additional life insurance for yourself of up to twice your annual base
        pay. You and the Company share the cost of this coverage.

The Executive Life Insurance Plan is just part of ARCO's "Business of Benefits"
effort to address your benefit needs with the same care with which we build our
business relationships.

This booklet gives you an overview of the Atlantic Richfield Company Executive
Life Insurance Plan, including a summary plan description (SPD) of ARCO's Basic
Life Plan. The full terms of the Executive Life Insurance Plan are contained in
the plan document on file with the Company.

The information presented in this booklet doesn't replace the official documents
that legally govern the plan's operation. In the event of any conflict between
this booklet and the official documents, the official documents will govern.

ARCO reserves the right to change or terminate this plan at any time.

There are a number of terms you need to know in order to understand how the plan
works. The first time each of these terms is used, it will appear in BOLDFACE
TYPE and will be followed by its definition or a page reference indicating where
that definition is located. We've also included a glossary at the end of this
booklet, which lists each term and shows you on which page its definition
appears.

Relations.

                                 WHO'S ELIGIBLE

YOU

As an executive, you're eligible for basic life coverage, executive life
coverage and optional life coverage.

YOUR DEPENDENTS

Basic life coverage is provided for your eligible dependents as explained on
page 4.

Eligible dependents include:

       . your legal spouse; and

       . your unmarried children:
         -to the end of the month in which their l9th birthday occurs;

                                       1
<PAGE>
 
         -from their l9th birthday to the end of the month in which their 25th
          birthday occurs, if they're full-time students at an accredited high
          school or college and are PRIMARILY DEPENDENT on you for support;

         -from their l9th birthday to the end of the month in which their 25th
          birthday occurs, if they're primarily dependent on you for support;
          and

         -age 19 or over for whom you can provide proof acceptable to Aetna Life
          Insurance Company, the insurance carrier, of your child's physical or
          mental incapacity for self-support.

"Primarily dependent" means that your child depends on you for more than half of
his/her financial support and qualifies for dependency tax status, as defined by
the Internal Revenue Code, on the date the claim was incurred.

If your child can't be declared as a dependent for federal income tax purposes,
he/she no longer qualifies as a covered dependent for that year. If he/she
qualifies for dependency tax status in any subsequent year and meets all other
eligibility requirements, he/she may again be covered as a dependent under this
plan.

Children include your:

       . natural children;

       . adopted children; and

       . any other children who:
         -live with you in a parent-child relationship; or
         -can be claimed as dependents for income tax purposes.

                              WHEN COVERAGE BEGINS

BASIC LIFE COVERAGE

YOU

You automatically receive basic life coverage on:

       . your hire date; or

       . the date you're first eligible for coverage;

whichever occurs first.

If you're disabled and away from work when coverage would otherwise begin,
you're covered once you return to work.

YOUR DEPENDENTS

Your eligible dependents are automatically covered on the date your coverage
begins.

EXECUTIVE LIFE COVERAGE

You must enroll for executive life coverage within 30 days of the later of:

       . the date of your eligibility for executive life coverage; or
       . the date you're notified of your eligibility.

If you enroll within the 30-day deadline and the insurance carrier denies you
coverage, the Company will self-insure you, as long as you've complied with the
insurance carrier's underwriting requirements. This includes completion of a
confidential health questionnaire, on which you're required to disclose all
known health problems and pre-existing conditions to the insurance carrier. You
may also be required to provide evidence of your good health.

                                       2
<PAGE>
 
If you want to enroll after the 30-day deadline, you must wait until the next
open enrollment period.

OPTIONAL LIFE COVERAGE

You may enroll for optional life coverage when you enroll for executive life
coverage. If you want to enroll after the 30-day enrollment deadline or make a
change to your optional life coverage, you must wait until the next open
enrollment period to do so.

Coverage begins when the insurance carrier approves your application. There's no
Company self-insurance for this coverage.

                               HOW THE PLAN WORKS

Basic life coverage is provided through group term life insurance. Executive
life coverage is funded by Corporate Owned Life Insurance (COLI) under a split-
dollar agreement. This means that the Company owns the life insurance policy and
guarantees you a share in its value through endorsement. That way, both you and
the Company receive part of the dollar value of the policy if you die.

Under certain circumstances--for example, if the insurance carrier denies you
executive life coverage--the Company may self-insure you.

Optional life coverage is provided by employee-owned insurance policies in which
the Company is assigned a collateral interest in the policies equal to its
CUMULATIVE PREMIUM OUTLAY--that is, its contributions. You and the Company share
the cost of this coverage--and both of you receive part of the dollar value of
the policies if you die.

                              WHAT COVERAGE COSTS

BASIC LIFE COVERAGE

ARCO pays the full cost of this coverage for both you and your dependents.

EXECUTIVE LIFE COVERAGE

ARCO pays the full cost of your executive life coverage.

As an active employee, if you elect the LUMP-SUM OPTION form of payment (see
page 7), once each year you pay a contribution equal to the amount of your
imputed income on the premiums the Company has paid. See the following table for
details. The Company then pays you a bonus equal to your contribution on a
before-tax basis. The net cost to you is any incremental income tax you may have
to pay on the bonus.

</TABLE>

If you're an inactive employee--that is, retired, on an approved leave of
absence or terminated--and you elect the lump-sum option, you're taxed on the
value of your executive life coverage.

There's no net cost to you if you elect the SURVIVOR INCOME OPTION (see page 7)
form of payment, to be paid to your BENEFICIARIES (see page 6).

OPTIONAL LIFE COVERAGE

You and ARCO share the cost of this employee-owned life insurance policy. Your
monthly contribution is determined by your age and coverage amount, as follows:

</TABLE>

                         HOW TO CALCULATE PLAN BENEFITS

BASIC LIFE COVERAGE

Basic life coverage consists of both life insurance and AD&D coverage.

LIFE INSURANCE

The plan pays the following life insurance benefit if you, your spouse or one of
your children dies:

<TABLE>
<CAPTION>
IF LIFE INSURANCE IS FOR...        THE BENEFIT PAID IS...
<S>                                <C>
       You                         $50,000
       Your spouse                 $ 2,000
       Each child                  $ 1,000
</TABLE> 

AD&D COVERAGE

The plan pays additional benefits according to the schedule below if you 
experience the loss:

    . as the result of an accident that occurs while you're insured; and

    . within one year after the accident.

The maximum AD&D benefit that will be paid for all losses resulting from one
accident equals I x ANNUAL BASE PAY (see this page).

<TABLE>
<CAPTION>
      FOR LOSS OF...             THE BENEFIT PAID IS...
      <S>                        <C>    
         Life                    1 x annual base pay
         Both hands
         Both feet               1 x annual base pay
         Sight in both eyes
         One hand and one foot
         One hand and one eye
         One foot and one eye
         One hand                50% x annual base pay
         One foot
         Sight in one eye
</TABLE>

"Loss of hand or foot" means that those limbs are completely severed at or above
 the wrist or ankle.
"Loss of sight" means the entire and irrecoverable loss of sight.

If the accident results in death, an AD&D benefit is paid in addition to the
plan's life insurance benefit.

The AD&D benefit is calculated using your annual base pay--that is, the regular
wages you were paid by the Company during the year, including all your pre-tax
contributions or deferrals of income to plans such as the

                                       4
<PAGE>
 
Atlantic Richfield Executive Deferral Plan.  It also includes benefit-bearing
cost-of-living allowances, such as:

       . Foreign Service Premium for expatriates; and

       . Alaska Benefits Base for Alaska-based employees

If your AD&D benefit isn't an even multiple of $1,000, it will be rounded to the
next higher multiple of $ 1,000. For example: $166,191.12 is rounded up to
$167,000.

An AD&D benefit won't be paid for any loss caused by:

       . suicide or attempted suicide; or

       . sickness or infection, unless the infection results from an accident
         covered by the plan.

EXECUTIVE LIFE COVERAGE

The plan pays an executive life benefit equal to:

                              3 X ANNUAL BASE PAY
                                     MINUS
                       THE BASIC LIFE BENEFIT OF $50,000.

The plan automatically adjusts your executive life coverage if you receive an
increase in your base pay. However, if your base pay increase causes your
executive life coverage to increase at least 10%, you may have to comply with
any insurance carrier underwriting requirements. Coverage increases take effect
as of the date your base pay increases. The Company will self-insure you if
coverage is pending with the insurance carrier.

If you relocate to the lower 48 states from Alaska or overseas, your executive
life benefit will be:

       . maintained at the level of coverage in effect before your transfer; or

       . based on your current base pay;

whichever is greater.

OPTIONAL LIFE COVERAGE

Optional life coverage for yourself pays a benefit equal to:

                              1 X ANNUAL BASE PAY
                                       OR
                              2 X ANNUAL BASE PAY.

The actual amount of your coverage is subject to the insurance carrier's
approval, and you may be required to comply with additional underwriting
requirements.

If you receive an increase in your base pay, additional optional life coverage
is subject to the insurance carrier's underwriting requirements.

                             WHO RECEIVES A BENEFIT

BASIC LIFE COVERAGE

YOU

The plan pays a benefit to you if:

       . you're dismembered;

       . your spouse dies; or

       . an eligible child dies.

                                       5
<PAGE>
 
YOUR BENEFICIARY

When you die, the plan pays a benefit to your beneficiary--that is, the
person(s) you designate to receive a benefit in the event of your death. To name
a beneficiary, you need to obtain a beneficiary designation form from Executive
Relations and return the completed form as soon as possible. You may designate
anyone you wish as your beneficiary, and you may change this designation at any
time. If you die and you've named more than one beneficiary, each receives the
same benefit amount, unless you've left written instructions otherwise with the
plan.

If you're married at the time of your death, your surviving spouse may be
entitled under applicable state law (e.g., community property laws) to a portion
of the benefit, whether or not your spouse is your designated beneficiary. In
that event, the benefits payable to any of your other designated beneficiaries
may be reduced.

If your beneficiary doesn't survive you and you haven't named any contingent
beneficiaries, a benefit is paid to the following survivors in the order listed:

       . your spouse;

       . your child(ren);

       . your parent(s);

       . your brothers(s) and sisters(s).

If you're survived by two or more persons in the applicable group of
beneficiaries to whom a benefit is to be paid, the payment will be divided
equally among them. If there are no survivors in any of the groups listed above,
payment will be made to your estate.

EXECUTIVE LIFE COVERAGE

Your beneficiary will receive a benefit from this plan if you die. If your
beneficiary doesn't survive you and you haven't named any contingent
beneficiaries, an executive life benefit will be paid to your estate.

To name a beneficiary, you'll need to complete a beneficiary designation form
and return it to Executive Relations. You may change this designation at any
time. See "Basic Life Coverage" on this page for additional information on
beneficiary designations.

OPTIONAL LIFE COVERAGE

Optional life coverage operates just like executive life coverage in how it
handles beneficiaries. See "Executive Life Coverage" above for details.

                             HOW BENEFITS ARE PAID

BASIC LIFE COVERAGE

The $50,000 basic life benefit and the AD&D benefit are tax-free. A benefit of
$10,000 or more will be automatically deposited by Aetna into an interest-
bearing checking account in your beneficiary's name. The beneficiary may
withdraw the account balance at any time. There are no fees or charges for this
service other than those usually charged for stop payments, check copies and
returned checks. However, the account is not insured by the Federal Deposit
Insurance Corporation (FDIC).

EXECUTIVE LIFE COVERAGE

You may choose either the lump-sum option or the survivor income option as the
form of payment to your beneficiary. This election may be changed once each year
during open enrollment. Your new election will take effect the following 
January 1.

                                       6
<PAGE>
 
LUMP-SUM OPTION

If you've chosen the lump-sum option, upon your death the insurance carrier will
pay your beneficiary a tax-free lump-sum benefit equal to your full coverage
amount.

SURVIVOR INCOME OPTION

If you've chosen the survivor income option, upon your death the insurance
carrier will pay the Company a tax-free lump-sum payment. In turn, ARCO will
make monthly survivor income payments to your beneficiary for 10 years. These
payments are taxable as ordinary income. Since the Company receives a tax-free
payment from the insurance carrier, the Company will increase the monthly
survivor payments by its corporate tax rate to offset some or all of the tax on
the benefits paid to your survivor.

OPTIONAL LIFE COVERAGE

After you die, the insurance carrier will pay your beneficiary a tax-free lump-
sum benefit.

                              HOW TO FILE A CLAIM

To file a claim for AD&D benefits, you or your beneficiary needs to obtain a
claim form from Executive Relations. After the form is completed, it should be
returned to Executive Relations. In the event of death, a copy of proof of the
accident that caused the death must accompany the claim form. A decision on the
claim will be made within 90 days after it was filed, and you or your
beneficiary will receive written notice of that decision.

To file a basic life, executive life or optional life claim for death benefits,
your beneficiary should obtain a claim form from Executive Relations and return
the completed form, together with a certified copy of the death certificate, to
Executive Relations. The claim will be processed as soon as administratively
possible.

                             HOW TO FILE AN APPEAL

CLAIM DENIAL

If the claim is partially or wholly denied, you or your beneficiary will receive
written notice of the denial within 90 days after the Company receives the
claim. This time limit may be extended for an additional 90 days in special
cases, but you or your beneficiary will be notified of the reasons for the
delay. In no event will this extension exceed 90 days.

The denial notice will explain the reasons for the denial, state the plan
provisions on which the denial is based, describe any additional information or
material required and discuss the procedures that must be followed if you or
your beneficiary wants a further review of the claim.

CLAIM REVIEW

If you or your beneficiary receives a claim denial notice, you or your
beneficiary may wish to file a formal request for a claim review with the
insurance carrier. This must be done in writing within 60 days of receiving the
claim denial notice, and a copy of the claim review request must be forwarded to
Executive Relations. In addition, you, your beneficiary or an authorized
representative may review pertinent documents and submit additional issues in
writing. If a claim review request isn't filed within this 60-day period, the
right to do so is waived.

Within 60 days (or 120 days in some cases) after the request is filed, the
insurance carrier will notify you or your beneficiary in writing of its final
decision, including the specific reasons for its determination.

If the insurance carrier finally denies the claim because of ineligibility to
participate in the plan or other issues unrelated to the payment of claims, you
or your beneficiary may request that ARCO's Welfare Plans Administrative
Committee review the claim.

                                       7

Executive Relations should be contacted for information on how to file this type
of appeal.

                               WHEN COVERAGE ENDS


BASIC LIFE COVERAGE

Your life insurance coverage terminates if your employment ends before you reach
age 62. However, if you:

       . retire with an immediate retirement allowance before age 62; or

       . leave the Company after age 62, with or without an immediate retirement
         allowance and are eligible for a deferred retirement allowance;

coverage terminates at the end of the month in which you turn 65.

You may be able to convert your terminated life insurance coverage to an
individual policy.  See page 12 for details.

Your AD&D coverage ends at the end of the month in which you:

       . retire or otherwise terminate employment;

       . are granted a leave of absence; or

       . are determined by the Company to be TOTALLY DISABLED (see page 9).

Your dependents' life insurance coverage terminates at the end of the month in
which:

       . you're no longer eligible for life insurance coverage under this plan;

       . your dependents are no longer eligible for coverage;

       . you're determined by the Company to be totally disabled (see page 9);

       . as an active employee age 65 or older, you retire;

       . as a retiree, you reach age 65;

       . you die; or

       . the plan no longer offers this coverage.

However, if your child:

       . is incapable of earning his/her living because of a mental or physical
         disability;

       . is primarily dependent on you for support; and

       . is covered under the plan when coverage would otherwise end because
         he/she has reached age 19, or age 25 if he/she is a full-time student
         or primarily dependent on you for support;

coverage may be continued throughout the child's incapacity as long as you're
covered under the plan. To qualify your child, you're required to provide proof
of your child's condition to the claims administrator within 31 days after the
end of the month in which he/she would no longer be eligible.

This provision doesn't apply to any child who has been issued an individual
policy under the conversion privilege (see page 12).

                                       8
<PAGE>
 
EXECUTIVE LIFE COVERAGE

Your executive life coverage ends if you leave the Company and aren't eligible
for an immediate retirement allowance.  However, you may be able to convert your
coverage to an individual policy.  See page 12 for details.

If you move to a grade position that isn't eligible for your current level of
executive life coverage, your executive life benefit will be:

       . maintained at the level of coverage in effect before your grade 
         change; or

       . based on your current base pay;

whichever is greater.

OPTIONAL LIFE COVERAGE

Your optional life coverage ends if you leave the Company. However, you may be
able to convert your coverage to an individual policy.  See page 12 for details.

If you move to a grade position that isn't eligible for optional life coverage,
the same provisions apply as under executive life coverage (see above).

                            HOW TO CONTINUE COVERAGE

BASIC LIFE COVERAGE

In general, basic life coverage may be continued as described below. However,
unless you're an active employee and not totally disabled, your AD&D coverage
and dependent coverage:

       . will be discontinued during a disability; or

       . will end on the last day of the calendar month in which you take a
         leave of absence or terminate employment.

ON A LEAVE OF ABSENCE

If you're granted a leave of absence, your right to continue coverage during the
leave depends on the provisions of the leave of absence you've taken.

For more details on basic life coverage during leaves of absence, contact
Executive Relations.

IF YOU'RE TOTALLY DISABLED

If you're totally disabled, as defined by ARCO's Executive Long-Term Disability
Plan, your basic life coverage will continue until you reach age 65.

If you remain totally disabled after your 65th birthday, or if you continue to
be an active employee after age 65 and then become totally disabled, your basic
life insurance will end.

BEFORE RETIREMENT BUT AFTER AGE 65

You may continue your basic life coverage under the plan on the same terms as
before age 65 if you remain an active employee and you're not totally disabled.

AT RETIREMENT

At Age 65 or Earlier. You may continue your current level of life insurance and
- ---------------------                                                          
that of your dependents until the end of the month in which you become age 65
if:

       . you retire with an immediate retirement allowance before age 62; or

       . after reaching age 62, you leave the Company with or without an
         immediate retirement allowance and you're eligible for a deferred
         retirement allowance.

The Company continues to pay the full cost of your basic life coverage after
your retirement.

After Age 65. If you retire after age 65, your basic life coverage ends at the

end of the month in which you retire.

EXECUTIVE LIFE COVERAGE

ON A LEAVE OF ABSENCE

Your executive life coverage continues if you're on an approved paid or unpaid
leave of absence.

IF YOU'RE TOTALLY DISABLED

If you become totally disabled--as defined by ARCO's Executive Long-Term
Disability Plan--while you're an active Company employee, your coverage will be
the same as if you retired with an immediate retirement allowance at the age you
became disabled (see this page).

BEFORE RETIREMENT BUT AFTER AGE 65

You may continue your executive life coverage on the same terms as before age 65
if you remain an active employee.

AT RETIREMENT

You may continue your current level of executive life coverage until the end of
the month in which you become age 65 if you leave the Company and are eligible
for an immediate retirement allowance. At the end of the month in which you
reach age 65, your executive life coverage will be reduced to:

                           1 X FINAL ANNUAL BASE PAY.

Unreduced Benefit.  Before your coverage is reduced, you'll be offered the
- ------------------                                                        
opportunity to keep your pre-age 65 executive life coverage.  If you do, you'll
be required to make contributions toward its cost.

Retirement Income Offer (RIO). Before you retire, the Company, at its sole
- ------------------------------                                            
discretion and subject to the terms and conditions it believes are appropriate,
may offer you the opportunity to irrevocably convert your post-age 65 executive
life coverage--I x final annual base pay--to additional retirement income.

This income is paid monthly for 15 years beginning one month after your
retirement date. Payments are taxable as ordinary income, but the Company will
increase the amount of these payments by its corporate tax rate to offset some
or all of the tax on the benefits you receive.

If you die after retirement and before age 65, your survivor will receive any
unpaid RIO payments plus a RIO-adjusted executive life benefit equal to:

                         2 X YOUR FINAL ANNUAL BASE PAY
                                     MINUS
                       THE BASIC LIFE BENEFIT OF $50,000.

This total benefit is paid in equal monthly installments over ten years.
Payments are taxable as ordinary income, but the Company will increase the
amount of these payments by its corporate tax rate to offset some or all of the
tax on the benefits your survivor receives.

If you die after retirement and at age 65 or later, your survivor receives only
your remaining RIO payments.

Policy Roll-Out. At its discretion, the Company may decide to roll-out the
- ----------------                                                          
insurance policy that's funding your final post-retirement benefit. At the time
of the roll-out, the policy's death benefit will be 100% of your final base pay.

                                      10
<PAGE>
 
The Company will withdraw the cash value that's equal to all premiums paid by
the Company during the policy's premium period. The remaining cash value will be
transferred to you when ownership of the policy is changed from the Company to
you. Any portion of the policy's transferred equity which exceeds your cost
while you're an  active employee may be taxed.

Once the policy has been rolled-out to you, the Company will have no other
obligation to provide you with a post-retirement death benefit under this plan.
You'll have full ownership rights to the policy. This means you can withdraw or
borrow against the policy's cash value to maintain the same or reduced level of
coverage.

In general, roll-out will occur once:

       . the policy's premium period has ended (currently, 10 years); and

       . you've reached age 65 or you've retired, whichever is later.

The policy won't be rolled-out if:

       . you've accepted the RIO; or

       . the Company has elected to pay your premiums on a pay-for-life basis.

OPTIONAL LIFE COVERAGE

ON A LEAVE OF ABSENCE

Your optional life coverage continues if you're on an approved paid leave of
absence. If you're on an approved unpaid leave, your optional life coverage
continues if you continue to make your contributions.

IF YOU'RE TOTALLY DISABLED

If you become disabled while you're actively employed by the Company, your
optional life coverage continues as long as you continue to make your
contributions.

BEFORE RETIREMENT BUT AFTER AGE 65

You may continue your optional life coverage on the same terms as before age 65
if you remain an active employee.

AT RETIREMENT

At your retirement, the Company will withdraw its cumulative premium outlay for
the policy. If your policy is paid up when you retire, your optional life
coverage will remain at its pre-retirement coverage level throughout your
retirement. If your policy isn't paid up when you retire and the Company's
outlay can't be covered by the cash value, you'll be required to pay the Company
the difference to keep your coverage. You may then:

       . continue making contributions to maintain your pre-retirement coverage
         level; or

       . discontinue making contributions and accept any residual coverage based
         on actual policy cash values, if any.

                                      11
<PAGE>
 
                               WHEN THE PLAN ENDS

The Company expects and intends to continue the plan indefinitely, but reserves
the right to amend or terminate it at any time.

If the plan is terminated, your coverage will end on the plan's termination
date. However, if you're totally disabled at that time, benefits will continue
to be available as described on pages 9, 10 and 11. All extended benefits are
subject to the plan's provisions and limitations.

At its discretion, the Company may offer you the opportunity to purchase the
life insurance policy according to the conversion procedures described below.

                           HOW TO CONVERT YOUR POLICY

BASIC LIFE COVERAGE

You may convert basic life coverage to an individual insurance policy. You may
convert your dependents' coverage to an individual policy only if your coverage
under this plan ends. If you're interested in converting to an individual
policy, contact Executive Relations.

Since an individual policy isn't a continuation of coverage under this plan, the
benefits that will be provided and the cost of the policy won't be the same as
provided under this plan.

EXECUTIVE LIFE COVERAGE

If you're not eligible for an immediate retirement allowance when you leave the
Company and you have at least five years of service with the Company, you may
purchase the Company's interest in the life insurance policy and convert your
executive life coverage to an individual insurance policy provided by the
insurance carrier without having to meet additional insurance carrier
underwriting requirements.

The policy's purchase price will equal the Company's total cumulative cost for
the policy or the cash value, whichever is greater. Payment must be made in a
single lump sum. You may withdraw or borrow from the policy to help pay its
purchase price. In addition, any portion of the insurance policy's equity which
exceeds your cost may be taxed.

OPTIONAL LIFE COVERAGE

When you leave the Company, you may convert your optional life coverage to an
individual insurance policy at your own expense. But first, the Company will
withdraw its cumulative premium outlay or the cash value, whichever is greater.
If the Company's cumulative premium outlay can't be covered by the cash value,
you'll be required to pay the Company the difference.

If the policy isn't fully paid up when you leave the Company and you wish to
convert your optional life coverage to an individual insurance policy, you may:

       . continue making contributions to maintain your coverage level; or
       . discontinue making contributions and accept any residual coverage based
         on actual policy cash values, if any.

           YOUR EXECUTIVE LONG-TERM DISABILITY BENEFITS--AN OVERVIEW

There may come a time when you're ill or injured and unable to work for an
extended period.  Executive Long Term Disability (ELTD) benefits from ARCO
provide you and your family with a financial safety net during this time.  The
monthly ELTD benefit is 60% of your pre-disability earnings, which include your
average Annual Incentive Plan (AIP) awards.  The maximum monthly benefit is
$25,000 and is paid through:

     . two individual policies, which together provide up to $12,000 of monthly
       coverage;

     . a group insurance policy, which provides up to $13,000 of monthly
       coverage; and

     . Company self-insurance, as needed.

In addition, the Cost-of-Living Allowance (COLA) adjustment feature provides you
with protection against inflation while you're disabled, subject to benefit
limits.

The Executive Long-Term Disability Plan is just part of ARCO's "Business of
Benefits" effort to address your benefit needs with the same care with which we
build our business relationships.

This booklet gives you an overview of the Atlantic Richfield Company Executive
Long-Term Disability Plan.  It's called a summary plan description (SPD).  The
full terms of the plan are contained in the plan document on file with the
Company.

The information presented in this booklet doesn't replace the official documents
that legally govern the plan's operation.  In the event of any conflict between
this booklet and the official documents, the official documents will govern.

ARCO reserves the right to change or terminate this plan at any time.

There are a number of terms you need to know in order to understand how the plan
works.  The first time each of these terms is used, it will appear in BOLDFACE
TYPE and will be followed by its definition or a page reference indicating where
that definition is located.  We've also included a glossary at the end of this
SPD, which lists each term and shows you on which page its definition appears.

If you have any questions about your ELTD benefits, contact Executive Relations.

                                 WHO'S ELIGIBLE

As an executive, senior manager (that is, grade 9, 10 or the equivalent), or an
employee with an ANNUAL BASE PAY (see page 2) of at least $175,000, you're
eligible for coverage under this plan.  Your plan participation is in lieu of
coverage under the Long-Term Disability Plan of Atlantic Richfield Company and
Its Participating Subsidiaries, which covers other Company employees.

                                 HOW TO ENROLL

You're temporarily covered under the plan on:

     . your hire date; or

     . the date you're first eligible for coverage.

                                       1
<PAGE>
 
To continue coverage, you must enroll within 31 days of the date:

     . you're first eligible for coverage; or

     . you receive notice of your eligibility;

whichever is later.

In addition, you must complete a confidential health questionnaire, on which
you're required to disclose all known health problems and pre-existing
conditions to the insurance carrier.  You also may be required to provide
evidence of your good health.

                              WHAT COVERAGE COSTS

The Company pays the full cost of your ELTD coverage.  However, all or a portion
of the insurance premiums paid by the Company will be reported as imputed
(taxable) income to you (see page 5).

                        WHEN ELTD BENEFIT PAYMENTS BEGIN

Your ELTD benefit payments begin after you've been disabled for 180 days.  These
180 days make up the ELIMINATION PERIOD.  No ELTD benefits are payable during
this time.

Disabilities lasting less than 180 days are considered short-term disabilities.
During the elimination period, you may receive regular pay, any sick pay you've
accrued, any federal and state disability benefits for which you may be
eligible, and/or retirement benefits from a Company retirement plan if you
choose to retire.

Any disability that recurs within 12 months will be considered the same
disability, and you won't be subject to an additional elimination period.
Instead, the time you're disabled will be combined and treated as one period of
total disability.

                         HOW TO CALCULATE PLAN BENEFITS

DEFINING "EARNINGS"

The ELTD benefit you receive depends on your predisability EARNINGS.

This first component of your earnings is calculated using your annual base pay
on the date you first became disabled.  Annual base pay is the regular wages you
were paid by the Company during the year, including all your pre-tax
contributions or deferrals of income to plans such as the Atlantic Richfield
Executive Deferral Plan (EDP).  It also includes benefit-bearing cost-of-living
allowances.  such as:

     . Foreign Service Premium for expatriates; and

     . Alaska Benefits Base for Alaska-based employees.

Another component of your earnings is the average of the AIP awards you received
for the three years before your disability began.  However:

     . if you were recently promoted and haven't yet received an AIP award, a
       percentage of your annual base pay, based on a guideline for your grade,
       is used to estimate your AIP average;

     . if you were eligible for fewer than three AIP awards, the average of the
       awards you did receive is used to determine your earnings; or

     . if you were eligible for an AIP award but didn't receive one, "0" will be
       used for that year to calculate the average of your awards.

                                       2
<PAGE>
 
The sum of these two components equals your earnings for purposes of calculating
your ELTD benefit.

The plan provides for automatic coverage increases resulting from increases in
your earnings, effective immediately on the date of your increase.

DEFINING "DISABILITY"

After the elimination period, the following three categories of disabilities
qualify for ELTD benefits:

     . You're considered to have a TOTAL DISABILITY if:
          - as the result of illness or injury, you can't perform the
            substantial and material duties of your occupation; and
          - you're receiving medical care that's appropriate for the condition
            causing the disability.

     . Although your disability may not fit the definition of "total
       disability," you'll qualify for ELTD benefits if you're considered to
       have a PRESUMPTIVE DISABILITY--that is, if illness or injury causes the
       entire and permanent loss of:

          - speech;
          - hearing in both ears;
          - sight in both eyes; or
          - the use of both hands, both feet, or of one hand and one foot.

     . You're considered to have a RESIDUAL DISABILITY--that is, partial
       disability--if:
          - during the elimination period and as the result of illness or
            injury, you:
            -- can't perform one or more of the substantial and material daily
               business duties of your occupation;
            -- lost at least 20% of your pre-disability earnings; and
            -- are receiving the medical care that's appropriate for the
               condition causing the disability; and
          - after the elimination period and whether or not you can perform some
            or all of your occupation duties, you continue to:
            -- lose at least 20% of your pre-disability earnings; and
            -- receive appropriate medical care.

AMOUNT OF MONTHLY BENEFIT

TOTAL DISABILITY/PRESUMPTIVE DISABILITY

After the elimination period, the plan pays an ELTD benefit if you have a total
disability or a presumptive disability.  This amount is equal to:

                      60% OF YOUR PRE-DISABILITY EARNINGS,
                             UP TO $25,000 A MONTH

RESIDUAL DISABILITY

A partial benefit is paid if you have a residual disability once the elimination
period is over.  This amount is equal to:

                          60% OF YOUR LOST EARNINGS 

For example: Let's assume that you have a residual disability. Your pre-
disability monthly earnings were $10,000, and you're now earning $8,000 a
month. Your monthly ELTD benefit is calculated this way:

                        [$10,000--$8,000] X 60%=$1,200.

COST-OF-LIVING ADJUSTMENT

After you've been disabled for 12 months--including the elimination period--your
benefits will be adjusted once each year, up to age 65, according to the All
Urban Consumer Price Index.  COLA adjustments are subject to maximum ELTD
benefit limits.

                                       3
<PAGE>
 
PAYMENTS FROM OTHER SOURCES

Your ELTD benefit won't be reduced if you receive payments from any other
sources such as:

     . Social Security disability and retirement benefits;

     . any benefits available under federal, state or local disability laws,
       workers' compensation and occupational disease laws, or similar
       legislation;

     . any occupational or non-occupational disability payments you receive from
       a Company-provided sick pay plan;

     . any retirement allowance you receive from the Atlantic Richfield
       Retirement Plan II or any other basic or supplemental retirement plan
       sponsored by the Company or any subsidiary; or

     . any work-related earnings, including income from self-employment, except
       if you're participating in a rehabilitation program as described below.

REHABILITATION BENEFITS

Under certain circumstances, if you're totally or presumptively disabled and
wish to participate in a rehabilitation program, you may continue to receive an
ELTD benefit if you:

     . actively participate in the rehabilitation program; and

     . are unable to perform the substantial and material duties of your
       occupation.

A rehabilitation program may include training and part-time work in your old
job.

Before you enroll in a rehabilitation program, you must obtain the approval of
the Company and the insurance companies.  Then, if your attending physician
and/or independent medical examiner certifies that you can participate and if
you're offered a suitable position, you must accept the position before ELTD
payments can begin.

If you participate in a rehabilitation program, you'll continue to receive
monthly ELTD payments.  However, they may be reduced by your earnings from the
rehabilitation program so that when they're added to the sum of these earnings,
they don't exceed your pre-disability earnings.

                                WHAT IS EXCLUDED

The plan won't pay an ELTD benefit for any illness or injury which:

     . is intentionally self-inflicted;

     . results when you commit or attempt to commit a felony; or

     . results from war or any act of war.

ELTD group policy and Company self-insured benefits may be limited if your
disability results from psychiatric conditions, alcoholism or drug addiction.
In these cases, an ELTD benefit will be paid during the first two years you're
totally disabled.  After that two-year period, benefit payments will be made
only if you're confined in a hospital and for the three-month period immediately
after your discharge.

                                       4
<PAGE>
 
                         WHEN ELTD BENEFIT PAYMENTS END

The maximum benefit period varies among the individual, group and Company self-
insured policies.  In general, an ELTD benefit is paid as indicated in the table
below.

     IF A CONTINUING COVERED 
        DISABILITY BEGINS...             AN ELTD BENEFIT IS PAYABLE...

     On or before age 60                 Up to age 65
     After age 60 and up to age 68       Up to age 70 or for up to 60 months,
                                         whichever happens first
     After age 68 but before age 75      For 24 months
     On or after age 75                  For 12 months

                      WHAT TAX ISSUES YOU SHOULD CONSIDER

The tax status of ELTD benefits varies among the individual, group and Company
self-insured policies, and for the individual policies, depends on the imputed
income option you've elected.  The amount of imputed income depends on such
factors as your age, the amount of your coverage and your effective rate of
income tax.

INDIVIDUAL POLICIES

Under the individual policies and while you're a Company employee, you may
choose:

     . to report any imputed income for the Company's premium costs.  In that
       case, any ELTD benefits you receive from the individual policies are tax-
       free; or

     . not to report any imputed income for the Company's premium costs that are
       in excess of the COLA premiums.  However, any ELTD benefits you receive
       from the individual policies will be taxed as ordinary income when paid.

You may change your imputed income option once each year during the annual open
enrollment period.  Your change will become effective on the following January
1.

Keep in mind that the Company's premium costs attributable to COLA adjustments
are reported as imputed income, but benefits derived from COLA are tax-free when
paid.

The following table outlines the additional reportable income to you, depending
on the imputed income option you elect and the benefit amount you receive.

GROUP POLICY

You must report the Company's premium costs for the group policy as imputed
income.  However, any ELTD benefits you receive from the group policy are tax-
free.

COMPANY SELF-INSURED COVERAGE

Premiums for the Company's self-insured coverage can't be reported as imputed
income, since no reportable income is associated with these benefits.  As a
result, you must pay tax on any self-insured benefits you receive.

                          HOW DEATH BENEFITS ARE PAID

SURVIVOR BENEFITS

If you die while receiving ELTD benefit payments, a benefit may be paid to your
BENEFICIARY (see this page).

Payment is made if you die before age 65.  In this case, one of the two
individual policies pays a lump-sum benefit to your beneficiary equal to three
times the monthly ELTD benefit you were receiving at the time of your death, as
long as you'd been disabled for at least six months.

The group policy also pays your beneficiary a lump-sum benefit equal to three
times the monthly ELTD benefit you were receiving at the time of your death.
However, this benefit is paid only if your death occurs after you'd been
receiving ELTD benefit payments for at least six months.

Neither the other individual policy nor Company self-insurance coverage pays a
survivor benefit.

BENEFICIARY DESIGNATION

Your beneficiary is the person(s) you designate to receive a benefit under the
plan in the event of your death.  If you die and you've named more than one
beneficiary, each receives the same benefit amount, unless you've left written
instructions otherwise with the plan.

To name a beneficiary, you'll need to complete a beneficiary designation form
and return it to Executive Relations.  You may change this designation at any
time.

If you're married at the time of your death, your surviving spouse may be
entitled under applicable state law (e.g., community property laws) to a portion
of the benefit, whether or not your spouse is your designated beneficiary.  In
that event, the benefits payable to any other of your designated beneficiaries
may be reduced.

For survivor benefits associated with the individual policy, payment will be
made to your estate if your beneficiary doesn't survive you and you haven't
named any contingent beneficiaries.  For the group policy survivor benefit, if
your beneficiary doesn't survive you and you haven't named any contingent
beneficiaries, benefits will be paid in equal amounts to your children under age
25.  If there are no eligible survivors in this case, payment will be made to
your estate.

                              HOW TO FILE A CLAIM

To file a claim for ELTD benefits, you should contact Executive Relations once
you become disabled to obtain claim forms.  After you and your doctor have
filled out the claim forms, you or, if you lack the legal or mental capacity,
your spouse or legal representative must sign the forms.

                                       6
<PAGE>
 
      YOU SHOULD FILE YOUR CLAIMS WITH EXECUTIVE RELATIONS WITHIN 60 DAYS
                 BEFORE THE SIX-MONTH ELIMINATION PERIOD ENDS.

                             HOW TO FILE AN APPEAL

CLAIM DENIAL

If your claim is partially or wholly denied, you'11 receive written notice of
the denial within 90 days after the claims administrator receives the claim, as
long as you've fulfilled the insurance carrier's requirements.  This time limit
may be extended for an additional 90 days in special cases.

The denial notice will explain the reasons for the denial, state the plan
provisions on which the denial is based, describe any additional information or
material required and discuss the procedures you must follow if you want a
further review of your claim.

CLAIM REVIEW

If you receive a claim denial notice, you may wish to file a formal request for
a review of your claim with the claims administrator.  You must do so in writing
within 90 days of receiving the claim denial notice and forward a copy of your
request to Executive Relations.  If you fail to file a request within this 90-
day period, you waive your right to do so.

Within 60 days (or 120 days in some cases) after you file your request, the
claims administrator will notify you in writing of its final decision, including
the specific reasons for its determination.

                               WHEN COVERAGE ENDS

Your coverage under the plan ends on whichever of the following happens first:

     . the day you begin a formal, approved unpaid leave of absence;

     . the day in which you leave the Company, including retirement;

     . the last day of the month in which you transfer to a position with the
       Company which isn't eligible for plan benefits;

     . the date you die; or

     . the date the plan is terminated.

If you're disabled and receiving an ELTD benefit at the time one of these events
occurs, benefit payments will continue to be paid according to the benefit
schedule on page 5.

                            HOW TO CONTINUE COVERAGE

Whether you:

     . take an unpaid leave of absence;

     . leave the Company before age 65; or

     . become ineligible for ELTD benefits because of a change in your position;

you may continue coverage under the individual policies only by paying the
required premiums.  You must also pay the required premiums to continue your
coverage if you've been disabled for less than 180 days.

                                       7
<PAGE>
 
However, group insurance and Company self-insured coverage may not be continued.

Should you continue coverage under the individual policies and receive any ELTD
benefits, those benefits are non-taxable when paid.

In addition, if you become ineligible for an ELTD benefit because of a change in
your position, you may participate in the long-term disability plan offered to
members of your new classification.

                               WHEN THE PLAN ENDS

The Company expects and intends to continue the plan indefinitely, but reserves
the right to amend or terminate it at any time.

If you're under age 65, or over age 65 and actively at work, the Company may
offer you, at its discretion, the opportunity to convert your policy.

                           HOW TO CONVERT YOUR POLICY

You may convert your ELTD coverage under the individual policies to an
individual insurance policy only by paying the required premiums.  However,
neither the group insurance policy nor Company self-insured coverage may be
converted.
