ITEMS 1. AND 2. BUSINESS AND PROPERTIES
 
                      CORPORATE HISTORY AND ORGANIZATION
 
  Atlantic Richfield Company ("ARCO" or the "Company") 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" or the
"Company" as used herein refer to Atlantic Richfield Company or Atlantic
Richfield Company and one or more of its consolidated subsidiaries.
 
  ARCO, including its subsidiaries, constitutes one of the largest integrated
enterprises in the petroleum industry. ARCO conducts operations in two
business segments: resources and products.
 
  ARCO's resources segment, known as its "upstream" operations, 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. ARCO's products segment, or its "downstream"
operations, includes the refining and transportation of petroleum and
petroleum products, the marketing of petroleum products on the U.S. West Coast
and the worldwide manufacture and sale of chemical products.
 
  ARCO's corporate structure is a complex of wholly-owned and majority-owned
subsidiaries and various divisions or units of the parent company, ARCO, that
have been delineated or defined for various operational reasons. Many of the
wholly-owned subsidiaries are formed to conduct ARCO's numerous international
operations. The principal majority-owned subsidiaries are ARCO Chemical
Company ("ARCO Chemical") and Vastar Resources, Inc. ("Vastar"). ARCO Chemical
was formed in July 1987, and it sold just under 20% of its common stock to the
public in October 1987; ARCO currently owns 82.7% of ARCO Chemical. Vastar was
formed in September 1993, and in July 1994 sold under 20% of its common stock
to the public; ARCO currently owns 82.3% of Vastar. Vastar is the primary
vehicle through which ARCO conducts natural gas and, to a lesser extent oil,
exploration, production and marketing in the Lower 48 States (the "Lower 48").
ARCO's principal subsidiaries are ARCO Chemical, Vastar, ARCO Alaska, Inc. (a
wholly-owned subsidiary through which ARCO conducts its Alaska operations) and
ARCO Transportation Alaska, Inc. (a wholly-owned subsidiary through which ARCO
holds its interest in the Trans Alaska Pipeline System ("TAPS")).
 
  ARCO also owns a 49.9% equity interest in Lyondell Petrochemical Company
("Lyondell"), which operates petrochemical processing and petroleum refining
businesses. ARCO originally sold just over 50% of Lyondell's common stock
("Lyondell Common Stock") to the public in January 1989; in August 1994, ARCO
received net proceeds of approximately $958 million from the sale of its 9%
Exchangeable Notes due September 1997 (the "Exchangeable Notes"). The
Exchangeable Notes are exchangeable at maturity, at ARCO's option, into shares
of Lyondell Common Stock, of which ARCO currently holds 39,921,400 shares, or
cash with an equal value. The number of shares or amount of such cash will be
determined based on a formula that takes into account the market price of
Lyondell Common Stock at maturity of the Exchangeable Notes. If ARCO elects to
deliver shares of Lyondell Common Stock upon maturity of the Exchangeable
Notes, ARCO's equity interest in Lyondell will be substantially reduced or
eliminated, depending on the market price of Lyondell Common Stock at such
time. See Notes 10 and 20 of Notes to Consolidated Financial Statements on
pages 47 and 55.

 Delivery Commitments
 
  ARCO has various long-term natural gas sales contracts covering the majority
of its production in Indonesia, the United Kingdom North Sea, and China,
substantially all of which are reservoir specific. While annual delivery
requirements may vary under these contracts, delivery obligations under the
agreements are essentially limited to producible reserves from specific
fields.
 
  In the Lower 48, Vastar has various long-term natural gas sales contracts
under which Vastar has contracted to deliver approximately 460 MMCFD in 1997.
Such obligation is presently the maximum requirement and declines to less than
103 MMCFD by 2003. The majority of these contracts are either index-based and
present little or no price risk, or are reservoir-dedicated, and present no
obligation to deliver if production from these reservoirs ceases. Vastar can
satisfy its existing natural gas delivery commitments from the gross natural
gas production controlled by Vastar, including proprietary production, royalty
gas, call rights on third party gas and gas obtained through joint operating
agreements. Vastar's total proprietary natural gas production was 872 MMCFD in
1996. There have been no instances in the last three years in which Vastar was
unable to meet its natural gas delivery commitments. Vastar also has
additional long-term contracts with certain cogeneration facilities pursuant
to which it delivered an average of 80 MMCFD in 1996. These contracts have an
average contract term of approximately 19 years, for which an average 13 years
remain. In 1996, the average price of gas sold under these contracts was
approximately $2.49 per MCF.

 Alaska
 
  Approximately 62% of ARCO's worldwide petroleum liquids production came from
ARCO's interests in Alaska, primarily in the Prudhoe Bay, Kuparuk River and
the Greater Point McIntyre Area fields on the North Slope of Alaska. ARCO's
net liquids production from Alaska in 1996 decreased 6% to 387,500 barrels per
day. ARCO's interests in Alaska included net proved reserves of 1,847 million
barrels of oil equivalent at December 31, 1996.
 
  ARCO operates the eastern half of the Prudhoe Bay field and has a 21.87%
working interest in the oil rim production from the field and a 42.56% working
interest in the gas cap production. ARCO's net petroleum liquids production
from the Prudhoe Bay field averaged 210,900 barrels per day in 1996, compared
to 226,600 barrels per day in 1995.
 
  ARCO is the sole operator of the Kuparuk River field and holds a 55.2%
working interest in the field. Its share of production from the field was
130,500 net barrels per day of petroleum liquids during 1996, compared to
140,700 net barrels per day during 1995. The Kuparuk Large Scale Enhanced Oil
Recovery project started full operations in September 1996 and is expected to
add 35,000 to 40,000 barrels of oil to daily gross production by 1999. NGLs,
obtained from the Prudhoe Bay field, are injected into existing wells in the
Kuparuk River field in order to recover additional barrels of oil and offset
natural field decline. ARCO estimates that this project will result in an
additional 200 million gross barrels (97 million net barrels to ARCO) of
incremental oil from the Kuparuk River field.
 
  In 1996, ARCO announced that the Alpine field, west of the Kuparuk River
field, is commercial. ARCO added 65 million barrels of net reserves for
primary recovery from its 56% working interest in the Alpine field.
 
  ARCO has established working interests in four of five Greater Point
McIntyre Area fields as follows: 30.1% in Point McIntyre, 40.0% in Lisburne,
and 50.0% in both West Beach and North Prudhoe Bay State. Additionally, ARCO
 
                                       4
<PAGE>
 
has a working interest in the Niakuk field, which is currently being
negotiated among the owners of that field. All five of the fields are
processed through the Lisburne Production Facility, which ARCO operates.
During 1996, liquids processed through the Lisburne Production Facility
averaged 207,000 gross barrels per day, or 51,000 net barrels per day.
 
  All of ARCO's petroleum liquids shipped from the North Slope fields are
transported to market through TAPS to terminal facilities at Valdez, and from
there to west coast locations by ARCO's ocean-going tankers.
 
 Lower 48
 
  During 1996, ARCO's consolidated Lower 48 operations had net production of
380 BCF of natural gas (including consumption) and 63 MMB of petroleum liquids
as compared to 359 BCF and 62 MMB in 1995, respectively. Exploration,
development and purchases (net of sales) replaced 124% of 1996 production on a
barrel-of-oil-equivalent ("BOE") basis.
 
  The primary vehicle for ARCO's Lower 48 exploration and production
operations is Vastar, of which ARCO owns 82.3%. Vastar, headquartered in
Houston, Texas, is engaged in the exploration for and the development,
production and marketing of natural gas and crude oil in selected major
producing basins in the Gulf of Mexico, the Gulf Coast, the San Juan
Basin/Rockies and the Midcontinent areas. For additional information about
Vastar, a copy of Vastar's 1996 Annual Report to Stockholders and 1996 Annual
Report on Form 10-K can be obtained by writing to Manager, Investor Relations,
Vastar Resources, Inc., 15375 Memorial Drive, Houston, Texas 77079. Vastar's
telephone number is (713) 584-6000.
 
  ARCO's other Lower 48 operations accounted for reserves at December 31, 1996
of 575 MMBOE, of which 85% were petroleum liquids. In 1996 net production from
ARCO's other Lower 48 interests was 54 MMB of oil equivalent, down slightly
from 55 MMB in 1995.
 
 International
 
  ARCO's international operations include both exploration and production.
ARCO's 1996 international production of petroleum liquids averaged 66,100
barrels per day, and came primarily from Indonesia and the North Sea. Natural
gas production averaged 730 MMCFD. Natural gas production from the United
Kingdom sector of the North Sea accounted for 45% and the Pagerungan and the
Offshore Northwest Java natural gas fields in Indonesia accounted for 43% of
ARCO's 1996 international natural gas production.
 
  ARCO's net proved reserves from international interests at December 31, 1996
were 967 MMBOE.
 
  Natural gas production from ARCO's Yacheng-13 field, situated in the South
China Sea, began on January 1, 1996. This gross $1.1 billion project,
developed with two partners, consists of two offshore production platforms,
onshore receiving facilities, the world's second longest subsea pipeline, the
480-mile pipeline to Black Point, near Hong Kong, and a 60-mile pipeline to
Sanya on Hainan Island. Ultimate production is expected to be more than 300
gross MMCFD. ARCO is the operator of, and has a 34.3% working interest in, the
Yacheng-13 field. During 1996, ARCO's net production was 69.3 MMCFD.
 
  In 1996, ARCO signed an agreement with Sonatrach, the Algerian state oil
company, to undertake a major enhanced oil recovery ("EOR") project in the
Rhourde El Baguel oil field. ARCO made a one-time $225 million acquisition
payment to Sonatrach. In addition, the agreement provides for ARCO to make an
investment of over $1.3 billion in the project. Under the production sharing
contract, ARCO will receive up to 49% of the project's annual production. ARCO
believes its EOR efforts should yield over 500 million incremental barrels of
crude oil equivalent over the 25-year life of the project and increase
production rates from the current 25,000 barrels per day to a peak of 125,000
barrels per day within the next five years. ARCO began receiving production on
July 1, 1996.

 Recent Developments
 
  Exploration activities by an ARCO operated consortium in which ARCO holds a
27.5% interest led to the discovery of an oil field called Al-Rayyan, in the
Persian Gulf offshore Qatar, from which production commenced in late 1996.
Delineation and appraisal of the discovery continues. ARCO, along with its co-
venturers, is currently negotiating with the governments of Qatar and Dubai a
contractual framework for the supply of natural gas to Dubai from the huge
Qatar North field, which is located in close proximity to the Al-Rayyan field.
 
  In early 1997, ARCO finalized a joint venture with LUKOIL, Russia's largest
oil company, to pursue exploration and production projects in the Commonwealth
of Independent States ("CIS"). The joint venture entity, LUKARCO, is owned 54%
by LUKOIL and 46% by ARCO. LUKARCO may invest up to $5 billion in various
projects over the next 18 years; ARCO has agreed to provide most of the
financing to LUKARCO. The first investment will be in the Caspian Pipeline
Consortium, a multi-party $2 billion project to construct a 900-mile pipeline
from the Tengiz oil field in Kazakstan to the Black Sea via Russia. LUKARCO
will hold a 12.5% interest, which will obligate LUKARCO to fund 25% of the
construction costs. In addition to the joint venture participation, ARCO owns
approximately 8% of LUKOIL's total equity as a result of ARCO's purchase of
convertible bonds in public offerings in 1995 and 1996.
 
  ARCO is conducting delineation drilling to appraise a discovery it made in
eastern Indonesia. Appraisal efforts are being conducted to determine whether
the discovery, called Wiriagar, holds the necessary 6 to 7 trillion cubic feet
of gas to support a two-train liquefied natural gas facility.
 
WORLDWIDE COAL OPERATIONS
 
  ARCO has interests in nine surface and underground coal mines in the western
United States and in northeastern Australia.
 
  In the United States, during 1996, ARCO owned and operated two surface mines
in Wyoming's Powder River Basin, Black Thunder and Coal Creek, and an
underground mine, West Elk, in western Colorado. Total U.S. coal shipments for
1996 were 52 million tons of coal.
 
  In December 1996, a subsidiary of ARCO acquired a 65% interest in Canyon
Fuel Company, a limited liability company that owns three mines--SUFCO,
Skyline and Soldier Creek--located in Utah's Uinta Basin. At December 31,
1996, ARCO's net investment at cost was $411 million. The three mines are
estimated to contain approximately 270 million tons of economically
recoverable coal reserves.
 
  In Queensland, Australia, ARCO has interests in three mines in the Bowen
Basin: Curragh, Gordonstone and Blair Athol. ARCO operates and holds an
effective 87% interest in Curragh, an 80% interest in Gordonstone and a non-
operating 31.4% interest in Blair Athol. As a result of the unanticipated
geological complexity of the Curragh mine, ARCO is studying several options,
which may include scaling back the level of operations at the mine. ARCO's net
share of total shipments in 1996 from Australian operations was 11 million
tons, of which 4.4 million tons was from Curragh.
 
  As of December 31, 1996, ARCO had long-term contracts to supply U.S. utility
companies with steam coal from its Black Thunder, Coal Creek and West Elk
mines and from its interest in Canyon Fuel Company. These contracts have
various termination dates with the longest contract extending to December 31,
2017. It is anticipated that these contracts will require approximately 70% of
planned production from these six U.S. coal mines in 1997. Approximately 80%
of planned 1997 production in Australia is committed under long-term
arrangements. Future revenues from these contracts in the U.S. and Australia
can be affected by periodic reopeners that adjust sales prices based on
prevailing market conditions.
 
  In total, ARCO shipped 63 million tons of coal during 1996 and had 1,669
million tons of recoverable coal reserves as of December 31, 1996. Reference
is made to Supplemental Information, Coal Operations on page 59 for further
information concerning reserves and shipments of coal.

REFINING AND MARKETING
 
  ARCO operates two U.S. 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.
 
  The combined annual average operable crude distillation capacities of these
two refineries, as measured pursuant to the standards of the American
Petroleum Institute, are shown in the following table:

  In 1996, the long-term crude oil supply agreement with Tosco Corporation
expired. ARCO received an average of 20,000 barrels per day of refined product
under this agreement in 1996.
 
  In connection with its refining operations, ARCO produces calcined coke and
operates electric cogeneration facilities.
 
  ARCO markets gasoline and other refined petroleum products to both consumers
and resellers. Gasoline is marketed under the ARCO(R) trademark through
independent dealers and distributors and directly to motorists at branded
retail outlets located in Arizona, California, Nevada, Oregon and Washington.
ARCO also sells gasoline to unbranded resellers. NGLs are sold directly to
end-use customers and the Watson Cogeneration Facility, which is 51% owned by
ARCO, and are also marketed through distributors. Jet fuels are sold directly
to airlines and the United States Department of Defense. Calcined coke is sold
to U.S. 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, 1996, there were 1,514 branded retail outlets, which
included franchisee and Company-operated am/pm(R) convenience stores and
SMOGPROS(R) Service Centers, and traditional service stations.

  In June 1996, ARCO and the other California gasoline marketers were required
to meet California Air Resources Board ("CARB") specifications standards for
automobile gasolines available for retail sale in California. In order to meet
the more stringent CARB standards with 100% of the gasoline produced at the
Los Angeles Refinery, ARCO completed in 1995 the necessary modifications and
upgrades at the refinery. The cost to meet both Environmental Protection
Agency ("EPA") and CARB standards was approximately $500 million.
 
  Total refined petroleum product sales, which include insignificant sales to
ARCO Chemical and Lyondell, for the periods indicated, were as follows:

  Total petroleum product sales differ from total petroleum products
manufactured due to the consumption of some products as refinery fuel, the
exchange of products with other companies, change in inventory levels, and the
purchase and resale of products not manufactured by ARCO.
 
 Recent Developments
 
  In 1994, ARCO acquired a 9.9% interest in China's third largest refiner,
Zhenhai Refining and Chemical Company ("ZRCC"). In late 1996, ARCO purchased
an additional interest in ZRCC. The newly issued convertible bonds, when
converted, will give ARCO a 20% interest in ZRCC, which has a modern refinery
complex.
 
  In addition, in 1996, ARCO entered into a joint venture project to produce
and upgrade heavy oil from the Orinoco region of Venezuela. Subject to certain
governmental approvals, the initial $2 billion phase of the project is
expected to be operational by 2001. ARCO will be a 30% owner.
 
  In early 1997, ARCO announced plans to build a 400 million pound-per-year
polypropylene manufacturing facility to be constructed adjacent to the Los
Angeles Refinery. ARCO estimates the $300 million plant will be operational in
1999.
 
TRANSPORTATION
 
  ARCO's transportation business includes ownership interests in pipelines in
Alaska, ownership interests in and operations of pipelines and terminalling
facilities in the Lower 48, and the operation of 10 ocean-going U.S. flag
tankers.
 
  In Alaska, ARCO has a 22.3% weighted average undivided ownership interest in
TAPS. TAPS consists of an 800-mile pipeline system used to transport petroleum
liquids from the North Slope of Alaska to the port of Valdez in south-central
Alaska. In addition, ARCO owns approximately 22% of the stock of Alyeska
Pipeline Service Company ("Alyeska"), which was established to design,
construct, operate and maintain TAPS for the owners. ARCO's undivided interest
in TAPS is proportionately consolidated for financial reporting purposes. TAPS
1996 total throughput averaged approximately 1,436,000 barrels per day.
 
  In the Lower 48, ARCO manages facilities for transportation and terminalling
of petroleum liquids, refined petroleum products, petrochemicals and natural
gas. In 1995, ARCO and Phillips Petroleum Company formed the
 
                                       8
<PAGE>
 
Seaway Pipeline Company ("Seaway"), a joint venture. ARCO has ownership
interests in petroleum liquids pipeline systems that include gathering lines
serving producing fields in California, New Mexico, Oklahoma, Texas and Utah,
and common carrier trunk lines extending from dock facilities and producing
areas to refineries and terminals. These pipelines moved petrochemicals and
refined petroleum products for all shippers (including ARCO) that properly
tendered these materials for transportation. In addition, ARCO owns or leases
and operates terminals that provide a variety of terminalling and
transportation services both to third-party customers and ARCO.
 
  ARCO has reorganized management responsibility for its transportation
business, which will result in a change in segment reporting of those
operations in 1997. ARCO Alaska Transportation, Inc. will be included with
exploration and production. ARCO Marine, Inc. will be included in refining and
marketing.
 
CHEMICALS
 
  The Company's chemicals operation consists of the businesses owned by ARCO
Chemical. ARCO currently owns 80,000,001 shares of common stock of ARCO
Chemical, which represent 82.7% of the outstanding shares.
 
  ARCO Chemical is an international manufacturer and marketer of chemicals
used in a broad range of consumer products. ARCO Chemical's core product is
propylene oxide ("PO"), which it produces through two distinct process
technologies based on indirect oxidation (peroxidation) processes that yield
co-products. One process yields tertiary butyl alcohol ("TBA") as the co-
product; the other process yields styrene monomer ("SM") as the co-product.
The two technologies are mutually exclusive such that either a dedicated
PO/TBA plant or a dedicated PO/SM plant must be built. ARCO Chemical's other
major products include PO derivatives, which include polyols and propylene
glycols ("PG"), TBA derivatives, which include methyl tertiary butyl ether
("MTBE") and ethyl tertiary butyl ether ("ETBE"). In September 1996, ARCO
Chemical sold its plastics business and, as a result, no longer manufactures
SM derivatives, but will continue to produce SM.
 
  In 1995, ARCO Chemical began marketing toluene di-isocyanate ("TDI"),
obtained under long-term supply agreements with Rhone-Poulenc. TDI and polyols
are combined to manufacture polyurethanes. In 1996, ARCO purchased Olin
Corporation's TDI and aliphatic di-isocyanate ("ADI") businesses, including
TDI and ADI production facilities located in Lake Charles, Louisiana and
related assets and technology.
 
  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); Rotterdam, the Netherlands
(PO, TBA and various derivatives including PG, propylene glycol ethers and
MTBE); Fos-sur-Mer, France (PO, TBA and various derivatives including PG,
polyols and MTBE); Lake Charles, Louisiana (TDI and ADI); and a joint venture
in Chiba, Japan (PO and SM). Other production facilities include polyols at
South Charleston and Institute, West Virginia, Rieme, Belgium, Kaohsiung,
Taiwan, and Anyer, West Java, Indonesia. ARCO Chemical owns a majority equity
interest in a second PO/SM plant at Channelview, Texas. The two equity
investors in the plant, which are limited partners, each take a substantial
portion of the SM output of the plant through long-term processing agreements.
In 1996, ARCO Chemical's Board of Directors gave final approval for the
construction of a new PO/SM plant at Rotterdam, scheduled for completion in
fourth quarter 1999, and for expansion of the Channelview, Texas PO/SM
capacity by early 1998.
 
  The following table shows ARCO Chemical's worldwide production capacity (in
millions of pounds per year, except where otherwise noted) for PO, SM and
certain key derivatives:

  Capacities shown are the production capacities that, as of December 31,
1996, ARCO Chemical believes it can obtain based upon plant design and subject
to certain onstream factors, product mix and other variable factors.
Capacities shown include the full capacity of joint-venture facilities. Plants
can and have exceeded these capacities for extended periods of time. In
addition, ARCO Chemical currently has processing arrangements at a third party
facility pursuant to which it has the capacity to produce an additional 12,000
barrels per day of MTBE or ETBE.
 
  In addition to raw material purchase agreements and product sales or
processing agreements with unrelated third parties, ARCO Chemical has
agreements with ARCO 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 for use in the production of
the Company's reformulated gasolines. ARCO and ARCO Chemical have entered into
long-term sales agreements providing for delivery of fixed quantities of MTBE.
Lyondell provides ARCO Chemical with a portion of the feedstocks purchased for
use at ARCO Chemical's manufacturing facilities in Texas. Lyondell also
provides certain plant services at these facilities. ARCO Chemical in turn
provides certain supplies and services 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
1996 Annual Report to Stockholders and 1996 Annual Report on Form 10-K can be
obtained by writing to Manager, Investor Relations, ARCO Chemical Company,
3801 West Chester Pike, Newtown Square, Pennsylvania 19073-2387. ARCO
Chemical's telephone number is (610) 359-2000.
 
                          EQUITY INTEREST IN LYONDELL
 
  ARCO owns a 49.9% equity interest in Lyondell, which is accounted for on the
equity method. Lyondell is a manufacturer and marketer of petrochemicals and,
through its participation interest in LYONDELL-CITGO Refining Company Ltd.
("LCR"), of refined petroleum products. Prior to 1989, Lyondell was a wholly-
owned subsidiary of ARCO. In August 1994, ARCO completed an offering of
Exchangeable Notes due 1997 which can be exchanged at maturity into Lyondell
Common Stock or, at ARCO's option, cash of an equal value. If ARCO elects to
deliver shares of Lyondell Common Stock at maturity, ARCO's equity interest in
Lyondell will be substantially reduced or eliminated. ARCO currently owns 39.9
million shares of Lyondell Common Stock. See Notes 10 and 20 of Notes to
Consolidated Financial Statements on pages 47 and 55.
 
  For the year ended December 31, 1996, Lyondell recorded total revenues of
approximately $248 million from sales to ARCO Chemical. Lyondell also provides
certain plant services at ARCO Chemical's Texas facilities. ARCO Chemical in
turn provides certain supplies and services to Lyondell. See "Downstream--
Chemicals." In addition, Lyondell currently purchases certain of its crude
oil, natural gas and NGLs requirements from ARCO and Vastar at prices based on
prevailing market prices. During 1996, Lyondell paid ARCO and its consolidated
subsidiaries an aggregate of $17 million under these agreements, arrangements
and transactions and received an aggregate of $318 million, principally from
sales of product to ARCO Chemical.
 
  For additional information about Lyondell, a copy of Lyondell's 1996 Annual
Report to Stockholders and 1996 Annual Report on Form 10-K can be obtained by

                                CAPITAL PROGRAM
 
  The Company's capital expenditures for additions to fixed assets (including
dry hole costs) totaled approximately $2.1 billion in 1996. In addition, 1996
capital expenditures included $1.2 billion for various investments including
ARCO Chemical's investments in a TDI manufacturing facility, ARCO's investment
in Canyon Fuel Company and investments in convertible bonds issued by ZRCC and
LUKOIL. The capital program for additions to fixed assets is budgeted at
$3.4 billion for 1997. 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 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 U.S. coal mines primarily serve competitive U.S. markets, where the
availability of specific transportation arrangements, primarily rail
transportation, 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 U.S. coal customers are electric utilities. The Company's
Australian mines are export-oriented, largely to Japan, and face worldwide
competition from Canadian, Indonesian, South African, U.S. and other
Australian producers.
 
  Key competitive factors in the chemicals markets include research and
development, product price, quality, reliability of supply, technical support,
customer service and potential substitute materials.
 
  The Company ranked as the sixth largest U.S. based oil company on the basis
of revenues in the most recent Fortune 500 list of U.S. industrial companies.
 
                                HUMAN RESOURCES
 
  As of December 31, 1996, ARCO had approximately 22,800 full-time equivalent
employees, of whom approximately 15% were represented by collective bargaining
agents.
 
                           RESEARCH AND DEVELOPMENT
 
  ARCO engages in research for new and improved products and methods for
operating its businesses principally at two facilities located at Newtown
Square, Pennsylvania and Plano, Texas. Total research and development expenses
were $106 million, $104 million and $109 million in 1996, 1995 and 1994,
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 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, sites associated with
discontinued operations and sites that were formerly owned by ARCO. 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. In addition, environmental loss
contingencies include claims for personal injuries allegedly caused by
exposure to toxic materials manufactured or used by ARCO. 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 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 Company's earnings.
 
  The Company's environmental remediation reserve of $577 million at December
31, 1996 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, sites
associated with discontinued operations and sites formerly owned by ARCO. The
Company has been named a potentially responsible party ("PRP") for 117 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 reserved by as much as $600 million.
 
  Approximately 45% of the reserve relates to sites associated with the
Company's discontinued operations, primarily mining activities in the states
of Montana, Utah and New Mexico. Another significant component relates to
currently and formerly owned chemical, nuclear processing, and refining and
marketing facilities, and other sites that 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 10% of
the total reserve. Substantially all amounts reserved 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. 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. The
EPA wintertime oxygenate gasoline program became effective in the fall of
1993. The EPA reformulated gasoline requirements became effective January 1,
1995 for the nine U.S. cities, including Los Angeles and San Diego, and other
areas with the worst ozone pollution. The CARB's specifications for
reformulated
 
                                      12
<PAGE>
 
gasoline, which are stricter than the EPA requirements, became effective for
retail sales on and after June 1, 1996. To comply with the EPA air quality
requirements and CARB standards, in 1995 ARCO completed 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 1993 the South Coast Air Quality Management District ("AQMD"), which sets
air quality standards for a five county area of southern California, including
Los Angeles County, adopted regulations requiring phased reductions of certain
pollutants. By 2003 the Los Angeles Refinery and the Wilmington calciner will
be required to achieve cumulative reductions from 1992 levels of oxides of
nitrogen (NOx) of 63% and oxides of sulfur (SOx) of 83%. As part of the
regulations, AQMD created a Regional Clean Air Incentives Market ("RECLAIM")
program under which regulated firms can earn credits for achieving emission
reductions below targeted levels. Those credits may then be bought and sold.
The Los Angeles Refinery plans to achieve the requisite levels of emission
reductions by a combination of reductions and acquisitions of credits,
substantial amounts of which have already been purchased. The AQMD is
currently considering modifications to the RECLAIM program, but nothing has
yet been finalized.
 
 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 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 $225 million per year. The Company
anticipates environment-related capital expenditures of approximately
$170 million and $175 million for 1997 and 1998, 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 $110 million per year. Cash payments for site remediation have
averaged $120 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 $230 million per
year.
 
  In addition to the reserve for environmental remediation costs, the Company
has also accrued, as of December 31, 1996, $950 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 (S)9607. These
alleged damages, arising out of ARCO's or its predecessors' alleged
activities, include restoration and compensable damages, assessment costs, and
prejudgment interest. On December 12, 1983, a lawsuit, styled Montana v. ARCO,
ex rel., (Case No. CV-83-317-HLN-PGH) was filed in the United States District
Court for the District of Montana. The claim, as of January 1, 1997, was for
damages of $764 million for alleged injuries to natural resources resulting
from mining and mineral processing operations. ARCO is contesting this demand.
In addition, on January 21, 1997, the court granted the Confederated Salish
and Kootenai Tribes of the Flathead Reservation ("Tribes"), a limited form of
intervention in Montana v. ARCO. The Tribes, as alleged trustees, have
asserted claims against ARCO for alleged injury to and loss of natural
resources located in the Clark Fork River Basin in southwest Montana. The
United States Department of Interior also stated an intention to make a claim
for natural resource damages in the Clark Fork River Basin.
 
                                      13
<PAGE>
 
  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. 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.)
 
  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 are named as
defendants in a consolidated complaint in the United States District Court for
the Eastern District of Washington, titled In re Hanford Nuclear Reservation
Litigation (CY-91-3015-AAM). In October 1994, the Department of Energy
determined that the government will indemnify ARCO and ARHCO for any judgment
or settlement in the action pursuant to the contract between ARHCO and the
Atomic Energy Commission and the provisions of the Price-Anderson Act.
 
  Following the March 1989 EXXON VALDEZ oil spill, numerous lawsuits seeking
compensatory and punitive damages and injunctions were filed by the State of
Alaska, the United States, and private plaintiffs against Exxon, Alyeska, and
Alyeska's owner companies (including ARCO Transportation Alaska, Inc.).
Alyeska and its owner companies have settled the civil damage claims by
federal and state governments and the lawsuits by private plaintiffs. Certain
issues relating to liability for the spill remain unresolved between the Exxon
companies, on the one hand, and Alyeska and its owner companies, on the other
hand.
 
  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), 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 The Anaconda Company, at
sites and locations throughout the United States. ARCO has settled with most
of the insurance company defendants. ARCO expects that a trial against the
remaining defendants will begin in 1997.
 
 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 13 of Notes to Consolidated Financial
Statements on page 49, and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
ITEM 3. LEGAL PROCEEDINGS
 
THE COMPANY
 
  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. The trial court dismissed all of
plaintiffs' claims other than their fraud claim. Plaintiffs appealed the
dismissal of their claims for restitution and indemnification and on June 27,
1996, the appellate court unanimously reversed the trial court's order.

  On January 24, 1996, ARCO (as successor to IS&R) was added as a defendant to
a class action suit pending in the United States District Court for the
Southern District of New York, German, et al. v. Federal Home Loan Mortgage
Corp., et al. (Case No. 93 Civ 6941), by plaintiff intervenors Naquan and
Naiya Thomas, minors, and their mother and guardian Kaii Henry. The complaint
in intervention names as defendants, in addition to ARCO, eight alleged former
processors of lead pigment and lead paint, the LIA, the City of New York and
its Housing Authority, and the owner of the building where plaintiffs reside.
Plaintiffs seek on behalf of themselves, and a purported class of children
under seven and pregnant women residing in dwellings in the City of New York
containing or presumed to contain lead paint, injunctive relief from all
defendants including orders to abate lead paint and to contribute to court-
administered funds to pay for abatement and medical monitoring and treatment.
The complaint alleges causes of action against the lead pigment defendants and
the LIA for negligence, strict products liability, fraud and
misrepresentation, breach of express and implied warranty, nuisance,
conspiracy, concert of action, and enterprise and market share liability. The
City of New York, its Housing Authority, and the owner of the building where
plaintiffs reside have filed cross-claims against ARCO, the other alleged
former processors of lead pigment and paint, and the LIA seeking
indemnification against or contribution toward any liability they (cross-
claimants) may have to plaintiffs.
 
  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), which 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. The trial court dismissed the complaint. The court of
appeals reversed and remanded the case to the Court of Common Pleas.
 
  On August 29, 1995, a purported class action was filed in the United States
District Court for the Eastern District of Louisiana, Jefferson v. Lead
Industries Association, Inc. (Case No. 95-2885), which seeks compensatory and
punitive damages on behalf of the named plaintiff and all Louisiana parents of
children who attained a blood lead level equal to or greater than 25
micrograms per deciliter before the age of six. The named defendants are ARCO
(as successor to IS&R), the LIA, NL Industries, Inc., Sherwin-Williams Co.,
SCM Corporation, Glidden Co., and Fuller-O'Brien Corporation. The complaint
states as theories of recovery strict liability, negligence, failure to warn,
fraud, and breach of express and implied warranty. The complaint also asserts
that the manufacturer of the lead pigment in any particular paint cannot be
determined by chemical analysis or any other means, and that plaintiff,
therefore, may rely upon market share and civil conspiracy to establish
defendants' liability. On June 3, 1996, the trial court dismissed the case.
The plaintiff has appealed the decision.
 
  In addition, the Company is a defendant in several lawsuits brought by
individuals that allege injury from exposure to lead paint. Such cases, in the
aggregate, are not material to the financial condition of the Company.
 
  On June 27, 1995, three former ARCO Alaska, Inc. employees filed an action
in the Alaska Superior Court in Anchorage, titled Tesch, et al. v. ARCO
Alaska, Inc. (Case No. 3AN-95-3320-CI), purporting to represent a class of all
ARCO Alaska, Inc. employees classified as exempt from overtime pay
requirements within the preceding three years. The plaintiffs claim that they
and other exempt employees were not actually exempt under Alaska law from
overtime pay and are entitled to pay for unpaid overtime and penalties in an
unstated amount. On May 7, 1996, the court denied plaintiffs' motion for class
certification and allowed further discovery. The plaintiffs recently filed a
motion for reconsideration of the May 7, 1996 ruling denying certification.
Employees of Alyeska in which ARCO Transportation Alaska, Inc. owns
approximately 22%, have filed two other purported class actions making similar
claims against Alyeska.
 
  On June 7, 1996, the case of Aguilar, et al. v. Atlantic Richfield, et al.
(Case No. 700810) was brought in the Superior Court of California for the
County of San Diego against ARCO and eight other refiner-marketers of CARB
reformulated gasoline. The plaintiffs allege that the defendants conspired to
restrict the supply, and thereby to raise
 
                                      15
<PAGE>
 
the price of CARB gasoline in violation of California state antitrust and
unfair competition law. The plaintiffs seek to recover treble damages,
restitution, attorneys fees, and injunctive relief on behalf of themselves and
a purported class of California residents who bought CARB gasoline after March
1, 1996 other than for resale.
 
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.
 
  Certain organic waste material is contained in the soil and ground water at
the site of the company's Monaca, Pennsylvania ("Beaver Valley") plant. In
1994, ARCO Chemical entered into a Consent Order and Agreement (the "Consent
Agreement") with the Pennsylvania Department of Environmental Protection
("PADEP") pursuant to which ARCO Chemical and PADEP agreed upon a work plan
for testing and remedial process design with regard to the conditions at the
Beaver Valley site. Under the terms of the Consent Agreement, ARCO Chemical
paid civil penalties totaling $363,000 in 1994. In addition, ARCO Chemical is
paying a penalty of $63,000 each year until the commencement of active
remediation at the Beaver Valley site, after which the amount of such annual
penalty shall be reduced based on the extent of remediation commenced at the
site. ARCO Chemical has an agreement with Beazer East, Inc., the successor to
Koppers Inc. (the previous owner of the Beaver Valley plant), whereby Beazer
East, Inc. agreed to pay for approximately 50% of the cost of the remediation.
ARCO Chemical sold the Beaver Valley plant assets to NOVA Chemicals Inc.
("NOVA") as of September 30, 1996, but currently retains ownership of the
Beaver Valley land, substantial portions of which are being leased to NOVA.
NOVA will assume ownership of such portions of the Beaver Valley land after
the occurrence of certain defined events. ARCO Chemical has retained
responsibility for the work plan and for certain additional remediation of the
Beaver Valley land that may be required by PADEP pursuant to the Pennsylvania
Land Recycling and Environmental Remediation Standards Act.
 
  On January 17, 1994, southern California experienced a major earthquake that
caused widespread property damage and major disruptions to utilities and
highways. Certain of ARCO's assets located in the region experienced varying
degrees of damage. A common carrier crude oil pipeline suffered ruptures, one
of which was involved in a fire of unknown origin. In addition, there was one
person injured, property damage, and oil spills into the Santa Clara and Los
Angeles Rivers. Each of the Los Angeles District Attorney and the State of
California Attorney General have notified the Company that pursuant to various
state statutes, some of which impose liability without fault, penalties and
damages in excess of $100,000 may be imposed on the Company. A settlement has
tentatively been reached. A class action lawsuit has been filed seeking
damages in excess of $10 million plus punitive damages on behalf of
individuals alleged to have been injured in the pipeline ruptures.
 
  On October 11, 1995, Vastar, on behalf of, and with ARCO's knowledge and
full cooperation, met with the United States EPA to apprise the EPA of certain
results obtained from Vastar's internal self-evaluation and audit program. The
results conveyed to EPA concern the Prevention of Significant Deterioration
("PSD") permit program under the federal Clean Air Act at Vastar's Ignacio
Blanco Fruitland ("IBF") coal degasification facilities. Through its self-
evaluation and audit program, Vastar previously determined that a PSD permit
may have been required for construction and operation of certain equipment at
the IBF operations due to unanticipated levels of carbon monoxide emissions.
Under federal law, EPA has the power to seek injunctive relief and civil
penalties for violations of the federal Clean Air Act. Liability for failure
to obtain a PSD permit under the Clean Air Act can be imposed without regard
to willfulness or negligence. Vastar has sought the benefits of EPA's
"Voluntary Environmental Self-Policing and Self-Disclosure Interim Policy
Statement," which may allow Vastar to avoid any punitive penalties, although
EPA may seek to recover what it considers to be the economic benefit of
noncompliance. Vastar has advised ARCO that on October 27, 1995, the company
made a written submittal to the EPA pursuant to the Interim Policy Statement.
In January 1997, the U.S. Department of Justice, acting on behalf of the EPA,
and the company agreed to settle the matter. Under the terms of the
settlement, Vastar agreed to pay a $137,949 civil penalty. In addition, ARCO,
the previous owner of the natural
 
                                      16
<PAGE>
 
gas compression facilities, agreed to pay a $519,463 civil penalty. Under the
terms of the settlement, the finalization of which is subject to certain minor
conditions precedent, neither Vastar nor ARCO admitted liability with respect
to the matter. The stipulation of settlement between the United States and
ARCO has been entered in the U.S. District Court for the District of Colorado
and the $519,463 ARCO civil penalty has been paid. In connection with the
conveyance of the IBF facilities from ARCO to Vastar, Vastar agreed to
indemnify ARCO against certain claims or liabilities to which ARCO could be
subject relating to ARCO's historical ownership and operation of the
facilities. Pursuant to such agreement, Vastar has reimbursed ARCO for the
amount of the ARCO civil penalty.
 
  In addition to the matters reported herein, from time to time, certain of
the ARCO'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).
 
TAX MATTERS
 
  In 1994, the Internal Revenue Service issued a Notice of Deficiency for
income tax relating to tax years 1983 through 1988. During 1996, the Company
has made significant progress in substantiating its position to refute the
claims originally asserted on the face of the Notice. ARCO has paid to the
Internal Revenue Service the amount of tax (and interest) that it believes is
due under the Notice and timely filed a petition in the U.S. Tax Court
challenging the balance.
 
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 1996.

  Certain Open Market Stock Purchases. Pursuant to the 1985 Executive Long-
Term Incentive Plan, as amended on February 24, 1997 (the "Amended LTIP"),
officers and key employees are eligible to receive shares of Common Stock upon
exercises of stock options, surrender of dividend share credits, and upon
grants of Restricted Stock. Pursuant to the compensation program for outside
directors, as amended in November 1996, outside directors are eligible to
receive shares of Common Stock upon grants of Restricted Stock, including
Restricted Stock granted in lieu of some or all of their cash compensation for
serving as directors and in connection with the termination of the Outside
Directors Retirement Plan. Pursuant to the Company's Capital Accumulation
Plans, employees are eligible to receive Common Stock in satisfaction of
employer and employee contributions thereunder. ARCO may satisfy these
obligations by issuing new shares of Common Stock. From time to time ARCO may
also purchase Common Stock on the open market and contribute it to treasury to
provide for current and future obligations to deliver Common Stock under each
of these plans; in addition, ARCO may purchase Common Stock on the open market
and contribute it to treasury in satisfaction of its obligations upon
conversion of the $3.00 Preference Stock and the $2.80 Preference Stock.
 
  Power of Board to Determine Terms 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. No shares of Preferred Stock have been issued.
 
  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
 
                                      21
<PAGE>
 
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.
 
  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.
 
  Redemption Provisions. The $3.00 Preference Stock is redeemable at the
option of the Company as a whole or in part at any time on at least thirty
days' notice at $82 per share plus accrued dividends to the redemption date.
The $2.80 Preference Stock is redeemable at the option of the Company as a
whole or in part at any time on at least thirty days' notice at $70 per share
plus accrued dividends to the redemption date. The holders of Preferred Stock,
if any, would have such redemption provisions, if any, as were designated by
the Board.
 
  Liquidation Rights. In the event of liquidation of the Company, the holders
of $3.00 Preference Stock and holders of $2.80 Preference Stock will be
entitled to receive, before any payment to holders of Common Stock, $80 per
share and $70 per share, respectively, together in each case with accrued and
unpaid dividends. Shares of $3.00 Preference Stock and shares of $2.80
Preference Stock will rank on a parity as to assets of the Company upon its
liquidation. Subject to the rights of creditors and the holders of $3.00
Preference Stock and $2.80 Preference Stock, the holders of Common Stock are
entitled pro rata to the assets of the Company upon its liquidation. The
holders of Preferred Stock, if any, would have such liquidation rights, if
any, as were designated by the Board.
 
  Preemptive Rights. No holders of shares of capital stock of the Company have
or will have any preemptive rights to acquire any securities of the Company.
 
                                      22
<PAGE>
 
  Liability to Assessment. The shares of Common Stock are fully paid and non-
assessable.
 
  Prohibition of Greenmail. Article VII of the Certificate of Incorporation
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% 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% 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 July 24, 1995, the Board of Directors of
the Company declared a dividend of one common share purchase right (a "Right")
for each outstanding share of Common Stock, par value $2.50 per share (the
"Common Shares"), of the Company. The dividend was paid on August 18, 1995 to
the stockholders of record on that date. Each Right entitled the registered
holder to purchase from the Company one Common Share at a price of $400.00 per
share (the "Purchase Price"), subject to adjustment. The description and terms
of the Rights are set forth in a Rights Agreement between the Company and
First Chicago Trust Company of New York, as Rights Agent.
 
  The Rights will be evidenced by and will be transferred with the Common
Share certificates until the Distribution Date. The Distribution Date is
defined as the earlier to occur of (i) 10 days following a public announcement
that a person or group of affiliated or associated persons has acquired
beneficial ownership of 15% or more of the outstanding Common Shares (an
"Acquiring Person") or (ii) 10 business days following the commencement of, or
announcement of an intention to make, a tender or exchange offer, the
consummation of which would result in a person or group becoming an Acquiring
Person. As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights will be issued.
 
  The Rights are not exercisable until the Distribution Date. The Rights will
expire on August 18, 2005 unless redeemed prior to that date by the Company.
The Purchase Price payable, and the number of Common Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution.
 
  In the event that any person becomes an Acquiring Person, each holder of a
Right, other than Rights beneficially owned by the Acquiring Person and its
affiliates and associates (which will thereafter be void), will have the right
to receive, upon exercise of each Right, that number of Common Shares having a
market value of two times the Purchase Price. If, after the Distribution Date,
the Company is acquired in a merger or other business combination with, or 50%
or more of its consolidated assets or earning power are sold to, the Acquiring
Person, each holder of a Right will have the right to receive, upon exercise
of each Right, that number of shares of common stock of the acquiring company
with a market value of two times the Purchase Price.
 
  At any time after an Acquiring Person crosses the 15% threshold and prior to
the acquisition by such person of 50% or more of the outstanding Common
Shares, the Board of Directors of the Company may exchange the Rights (other
than Rights owned by the Acquiring Person), in whole or in part, at an
exchange ratio of one Common Share per Right.
 
  The Board of Directors of the Company may redeem the Rights in whole, but
not in part, at a price of $.01 per Right prior to the acquisition by an
Acquiring Person of 15% or more of the outstanding Common Shares. The terms of
the Rights may be amended by the Board of Directors of the Company without the
consent of the holders of the Rights, except that after any person becomes an
Acquiring Person no such amendment may adversely affect the interests of the
other holders of the Rights.
 
  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.

                       CAUTIONARY STATEMENT FOR PURPOSES
                    OF THE "SAFE HARBOR" PROVISIONS OF THE
               PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
 
  The Company desires to take advantage of the "safe harbor" provisions
contained in Section 27A of the Private Securities Litigation Reform Act and
is including this statement in its 1996 Form 10-K in order to do so.
 
  From time to time ARCO's management may wish to make forward-looking
statements to inform more fully existing and potential security holders
regarding various matters, including without limitation, projections regarding
future income, oil and gas production, production and sales volumes of refined
petroleum products and petrochemicals, replacement of oil and gas reserves,
capital spending, as well as predictions as to the timing and success of
specific projects. Such forward-looking statements are generally accompanied
by words such as estimate, project, predict, or expect, that convey the
uncertainty of future events or outcomes.
 
  The factors identified in this statement are believed to be important
factors (but not necessarily all of the important factors) that could cause
actual results to differ materially from those expressed in any forward
looking statement made by or on behalf of the Company. Unpredictable or
unknown factors not discussed herein could also have material adverse effects
on forward looking projections. The Company does not intend to update these
cautionary statements.
 
UPSTREAM FACTORS AFFECTING PERFORMANCE
 
 Volatility and Level of Crude Oil and Gas Prices
 
  The Company's projections as to the level of future earnings are based on
certain assumptions as to the future prices of crude oil and natural gas.
These price assumptions are used for planning purposes and the Company expects
they will change over time. Any substantial or extended decline in the actual
prices of crude oil and natural gas could have a material adverse effect on
the Company's financial position, results of operations and on quantities of
crude oil and natural gas reserves that may be economically produced. These
prices historically have been volatile and may vary based on factors affecting
commodities markets generally, such as political instability in producing
regions, changes in market demand, and fluctuations in political, regulatory
and economic climates throughout the world.
 
 Ability to Maintain Production Rates and Replace Reserves
 
  Projecting future rates of oil and gas production is inherently imprecise.
Producing oil and gas reservoirs generally have declining production rates.
Production rates depend on a number of factors, including crude oil prices,
market demand, and the political, economic and regulatory climate.
 
  The other major factor affecting production rates is the Company's ability
to replace depleting reservoirs with new reserves through enhanced recovery,
acquisition or exploration success. Exploration success is impossible to
predict particularly over the short term, where results vary widely year to
year; moreover, the ability to replace reserves over an extended period
depends not only on the total volumes found, but on the cost of finding and
developing such reserves. Depending on the general crude oil price
environment, the Company's finding and development costs may not justify the
use of resources to produce such reserves. There can be no assurances as to
the level or timing of success, if any, that the Company will be able to
achieve in acquiring or finding and developing additional reserves.
 
DOWNSTREAM FACTORS AFFECTING PERFORMANCE
 
  A substantial proportion of the Company's total income for the foreseeable
future is expected to come from operations downstream of oil and gas
production and sale, chiefly refining and marketing of gasoline and other
products and chemical operations. It is possible that the Company could meet
its projections for upstream operations and still fail to meet overall
projections made in various forward looking statements.
 
 
                                      24
<PAGE>
 
 Products
 
  The Company conducts significant refining and marketing operations in the
five western states of the U.S. Results of these operations will be
significantly affected by changes in the volumes sold and the prices received
on those volumes. These, in turn, are influenced by such factors as the
general economic condition of the western states, which affects the overall
demand for gasoline and other refined products, the actions taken by
competitors, including both pricing and the expansion and retirement of
refining capacity in response to market conditions, environmental regulations
issued by the state and federal government, including particularly regulations
dealing with gasoline composition and characteristics. Overall profitability
of the Company's refining and marketing operations depends heavily on the
margin between the price of crude oil and/or purchased products and the sales
price of products produced and/or purchased. These margins may fluctuate
depending upon changes in the price of crude oil and the relative
supply/demand balance for products. Political constraints either in the form
of express legal requirements or general political pressure may also limit the
margins otherwise available to the Company. Projections as to the level of
future earnings are dependent on the Company's ability to produce and sell the
volumes of refined products and to achieve the margins on which those
projections are based. Products volumes and margins historically have been
volatile and may vary with factors such as the national and regional economy,
market demand, regulatory changes, the price of crude oil, and the ability of
regional refiners and the Company to provide a sufficient supply of refined
products.
 
 Chemical Operations
 
  ARCO derives a material portion of its net income from the chemical
operations of its affiliates. Results of its chemical operations are
influenced by changes in the cost of raw materials, the availability of
substitutes, changes in the supply/demand balance, and actions taken by
competitors to increase or decrease their production volumes. Earnings with
respect to chemical operations typically are cyclical and show marked
responses to changes in the overall economic climate. Projections as to the
level of future earnings are dependent on achieving the volumes and margins
for chemicals on which those projections are based. Volumes and margins for
these petrochemical products are strongly influenced by national and world
economic growth, market demand, the availability of substitutes, regulatory
changes, the cost of raw materials, and the worldwide capacity to produce
these petrochemical products.
 
EFFECT OF POLITICAL AND REGULATORY INSTABILITY ON COMPANY'S OPERATIONS
 
  The Company's ability to conduct acquisition, exploration, development and
production of oil and gas interests is dependent on the political and
regulatory climate in the particular geographic regions where the properties
are located. The Company's ability to negotiate and implement specific
projects in a timely and favorable manner may be impacted by political
considerations unrelated to or beyond the control of the Company. Political
instability may result in insurgencies and military operations that could
interfere with the Company's operating facilities located throughout the
world. Possible political and regulatory actions by governments may affect
future results in unpredictable ways.
 
OPERATING HAZARDS
 
  The Company's drilling operations are subject to various hazards common to
the industry, including explosions, fires, and uncontrollable flows of oil and
gas. They are also subject to the additional hazards of marine operations,
such as capsizing, collision and damage or loss from severe weather
conditions. Similarly, the Company's refining and petrochemical operations are
subject to explosions, fires, and damage from severe weather conditions.

conditions and other factors; however, the Company presently expects that
dividends will continue to be paid.

     ARCO's 1996 earnings were 21% higher than 1995 earnings which, in turn,
were 50% higher than 1994 earnings. The 1996 operating results benefited from
higher crude oil and natural gas prices, increased natural gas volumes, higher
refining and marketing volumes, and lower exploration and interest expense.

These combined benefits were partially offset by lower earnings from ARCO's
chemical interests.  1996 cost savings from ARCO's efforts to achieve a low-cost
operating structure exceeded $450 million after tax, compared to the benchmark
year of 1993.

     In 1995, operating results benefited from higher ARCO Chemical Company
earnings, higher crude oil prices, cost savings resulting from ARCO's 1993 and
1994 restructurings, and higher earnings from ARCO's equity interest in Lyondell
Petrochemical Company.  These benefits were partially offset by lower refining
and marketing margins and lower domestic natural gas prices.  1995 cost savings
totaled $330 million after tax, compared to the benchmark year of 1993.

     Higher crude oil and natural gas prices, growth in natural gas volumes and
lower exploration expenses combined to benefit earnings in 1996.

     In 1995, earnings reflected the effect of higher crude oil prices, higher
natural gas volumes and reduced operating expenses, partially offset by lower
domestic natural gas prices and higher exploration expenses.

     Worldwide petroleum liquids production decreased in both 1996 and 1995 as a
result of natural field declines. In Alaska, increased production from the
Greater Point McIntyre fields was more than offset by production declines in the
Prudhoe Bay and Kuparuk River fields. Internationally, new production volumes
from the Rhourde El Baguel field in Algeria in the latter half of 1996 and the
Blenheim field in the United Kingdom in 1995 were more than offset by decreases
in volumes received from Indonesian production sharing contracts in both years.

     U.S. natural gas production growth in 1996 and 1995 came primarily from
Vastar Resources, Inc.'s fields in the San Juan Basin and the Gulf of Mexico.

     In 1996, international natural gas production was higher as a result of the
startup of the Yacheng-13 field in the South China Sea and higher production in
the United Kingdom and Indonesia. A full year of production from the Gawain
field contributed to the increase in United Kingdom natural gas sales.

  Production from Indonesian natural gas fields in 1996 and 1995 grew as a
result of greater contract takes by purchasers. Unseasonably warm weather in
late 1995 contributed to the decline in United Kingdom natural gas sales.

  In 1996, a number of projects were started that will contribute growth to
ARCO's exploration and production operations. ARCO became a partner with
Sonatrach in Rhourde El Baguel, Algeria's second largest oil field. This added
218 million barrels of oil to ARCO's reserves. In Alaska, the Alpine field west
of the Kuparuk River field on the North Slope should start production in 2000.
ARCO added 65 million barrels of proved reserves for primary recovery from
Alpine. In eastern Indonesia, ARCO is drilling the sixth delineation well to
appraise the Wiriagar gas discovery's potential for a large liquefied natural
gas project.

</TABLE>

     Record production in the U.S. in 1996 was more than offset by lower average
U.S. coal prices, higher worldwide operating and maintenance costs, and the
exchange rate effect of a stronger Australian currency.  U.S. volumes were up
13% in 1996 as production increased at all U.S. mines.  Australian volumes were
8% lower because of equipment down time and labor-related interruptions.

     Due to the unanticipated geological complexity of ARCO's Curragh mine in
Australia, the current cost of recovering coal is significantly more than
originally estimated.  Therefore, the Company is studying several options to
improve profitability and efficiency which may include scaling back the level of
operations at the mine.  Total shipments from the mine were 5 million tons in
1996.

     In December 1996, a subsidiary of ARCO acquired a 65% interest in Canyon
Fuel Company, a limited liability company which owns three mines in Utah.  The
mines produced 9.4 million tons in 1996 and have estimated recoverable reserves
of 270 million tons.  At December 31, 1996, ARCO's net investment at cost was
$411 million. The results of the acquired mines were not included in
ARCO's 1996 consolidated net income.  The pro forma effect of including the
earnings from the acquired mines was immaterial to ARCO's consolidated net
income in 1996.

     In 1995, worldwide production increases and higher coking and export steam
coal prices for Australian production were partially offset by lower average
U.S. prices. Earnings included a net charge of $10 million, primarily related to
the impact on deferred taxes of an Australian tax rate increase.

     Operating results in 1996 reflected higher refined product prices and sales
volumes, partially offset by the impact of higher crude oil prices, higher
prices and volumes of purchased refined products and increased operating costs.
The increased operating costs were associated with maintenance turnarounds and
charges for environmental and other remediation. Refined products were purchased
from third parties to supplement ARCO's refinery production.

MANAGEMENT'S DISCUSSION 
 
     The Company's margins in 1996 were highest in the second and third quarters
and declined in the fourth quarter, reflecting rising oil prices and declining
products prices. The declining product prices resulted primarily from extremely
competitive conditions in the Los Angeles area in the 1996 fourth quarter. As a
result, the Company had an after-tax loss of $8 million for the quarter,
compared to after-tax earnings of $53 million for the 1995 fourth quarter.
Margins remained weak in January 1997.

  In 1995, the impact of higher crude oil costs more than offset increased sales
prices and volumes and lower operating expenses.

     ARCO was able to achieve higher sales in 1996 and 1995 by a combination of
increased refining capacity resulting from modifications and debottlenecking
projects necessary to make reformulated gasolines and increased refined products
purchases. The increase in other sales in 1996 reflected the sale of
intermediate products as a result of turnarounds.

     The operating results reflected lower Trans Alaska Pipeline System (TAPS)
tariff revenues and a 6% decrease in TAPS volumes compared to 1995.  In 1995,
increased volumes and earnings from the commercial pipeline and terminal
businesses in the Lower 48 nearly offset declines in earnings from TAPS.

     The 1996 transportation results included a net after-tax charge of
approximately $20 million for the writedown of ARCO's interest in the Point
Arguello Pipeline and a TAPS tariff refund of $14 million (reflected as a
benefit in ARCO's exploration and production special items), partially offset by
a gain on a pipeline interest sale.

     The 1994 results included net charges of approximately $20 million after
tax related to personnel reductions, a loss on the sale of Midcontinent product
pipelines, and costs associated with the Southern California earthquake,
partially offset by a tax credit.

*Reflects ARCO's share of ARCO Chemical net income after segment adjustments,
primarily for interest expense and minority interest.

     ARCO Chemical's earnings declined in 1996 primarily as a result of
significantly lower styrene monomer (SM) margins.  The SM margins were lower as
sale prices decreased more than raw material costs.  SM sale prices declined
significantly versus the 1995 period as production from increased industry
capacity depressed SM market prices.

     In 1995, ARCO Chemical's earnings reflected higher margins for propylene
oxide (PO) and its derivatives and SM.  The margin improvements were primarily
attributable to higher prices, which more than offset increased costs of raw
materials. Both prices and margins for SM decreased in the second half of 1995
as worldwide demand declined, reversing the trend during the early part of 1995.

     ARCO Chemical reported that its 1994 results included an after-tax charge
of $19 million for corporate restructuring and a $12 million benefit from
insurance proceeds.

     In 1996, ARCO Chemical undertook actions to focus on its core PO and
derivatives businesses.  ARCO Chemical sold its plastics business in September
1996, and purchased an isocyanates business in December 1996. ARCO Chemical
announced plans to build a PO/SM plant in Rotterdam, Netherlands, and expand its
existing PO/SM capacity in Channelview, Texas.

     ARCO has a 49.9% interest in Lyondell. Lyondell's net income declined in
1996 primarily because of lower olefins margins resulting from higher feedstock
costs.  Lyondell's results in 1995 benefited from higher olefins margins and
increases in its polymers business following the acquisition of additional
capacity in 1995 and strong aromatics performance at LYONDELL-CITGO refinery.
The strong performance in the olefins and polymers markets in the first nine
months of 1995 was followed by a sharp market decline in the latter part of the
year.

     The net benefits in 1996, and to a greater extent in 1995, were from
insurance settlements related to certain past environmental expenses.  In 1996,
the net benefit was also lower due to final charges for previously reported
personnel reductions, and less interest income from short-term investments.  The
insurance settlements, the absence of charges for personnel reductions and other
items, and lower insurance and corporate staff expense resulted in a net after-
tax benefit in 1995, compared to a net after-tax expense in 1994.

     In 1996, higher crude oil and natural gas prices, increased natural gas
marketing activity and higher natural gas production volumes were partially
offset by decreased crude oil trading activity.

     Sales to third parties of natural gas (produced and purchased volumes)
increased to 3.8 billion cubic feet per day in 1996, up from 2.8 billion cubic
feet per day in 1995. The majority of the increase was generated by Vastar,
where natural gas revenues increased from $1.3 billion in 1995 to $2.5 billion
in 1996. The remainder of the increase came from international production in the
South China Sea, North Sea and offshore Indonesia. Sales to third parties of
petroleum liquids (both produced and purchased volumes) were down 42,200 barrels
per day, compared to 1995.

     In downstream businesses, higher refined products prices and volumes were
partially offset by a decline in chemical products prices and volumes. ARCO
Chemical sales and other operating revenues declined $327 million in 1996.

     In 1996, trade purchases were higher as a result of increased natural gas
marketing activity and higher third-party purchases of refined products. Natural
gas marketing purchases increased to 2.1 billion cubic feet per day in 1996, up
from 1.3 billion cubic feet per day in 1995. Prices for purchased volumes of
natural gas, crude oil and refined products were also higher in 1996.

     In 1995, trade purchases increased as a result of higher chemical feedstock
costs and crude oil prices, partially offset by decreased crude oil trading
activity. Crude oil trading purchases decreased 73,300 barrels per day in 1995,
compared to 1994.

     ARCO's 1996 operating expenses reflected higher oil and gas lease operating
and other support costs for new international operations, partially offset by
lower operating costs in Alaska. In addition, refining and marketing and coal
operating expenses were higher in 1996. The higher refining and marketing
expenses were associated with maintenance turnarounds, marketing improvements
and charges for environmental and other remediation. The higher coal expenses
were associated with increased production volumes and maintenance.

     The 1995 operating expenses were lower in the following areas: domestic
exploration and production - lease operating and other support; refining and
marketing - maintenance, outside services and personnel; transportation -
maintenance; and insurance costs. The lower maintenance expense was related to
the level of scheduled refinery turnarounds and less required work on the Trans
Alaska Pipeline in 1995. ARCO Chemical tolling costs associated with toluene di-
isocyanate sales, which began in 1995, partially offset the reductions.

     The decline in 1996 exploration expense primarily reflected lower dry hole
costs in ARCO's international exploration and production operations. Higher
exploration expenses in 1995 primarily reflected dry hole costs associated with
South China Sea exploration, partially offset by lower exploration costs in
Alaska.

     The higher taxes other than income taxes in 1996 primarily reflected the
impact of higher crude oil prices on U.S. production taxes and the impact of
higher crude oil prices and production volumes in the United Kingdom. The
reduction in 1995 primarily reflected the absence of an accrual for certain tax
issues recorded in 1994.

     The decline in interest expense in 1996 reflected lower average long-term
debt balances outstanding during the year, compared to prior years.

     Unusual items in 1996 were final charges for personnel reductions, the
majority of which were reported as unusual items in 1994.

Gain on Issuance of Stock by Vastar Resources, Inc.

     In July 1994, Vastar consummated the sale of 17,250,000 shares of its
common stock to the public at an initial offering price of $28 per share. Vastar
was a wholly owned subsidiary of ARCO prior to the offering. ARCO realized an
after-tax gain of $273 million as a result of the initial public offering by
Vastar. At December 31, 1996, ARCO owned 80,000,001 shares of Vastar's common
stock, which represented 82.3% of Vastar's outstanding common stock.  Vastar's
results of operations are included in ARCO's Lower 48 results in the exploration
and production segment.

     The Company's effective tax rate was 34.7% in 1996, compared to 31.6% in
1995 and 28.3% in 1994.  The higher effective tax rate in 1996 primarily
reflected a decrease in the benefit from the dividends received tax deduction
and the absence of the 1995 foreign deferred tax asset valuation allowance
benefit.

     The higher effective tax rate in 1995 primarily reflected the effect of
higher pretax income, without an increase in tax credits compared to 1994.

Financial Condition and Liquidity

     Cash and cash equivalents and short-term investments totaled $2.2 billion
at year-end 1996 and short-term borrowings were $1.2 billion.  Working capital
was $1.8 billion lower at the end of 1996, primarily reflecting the addition to
current liabilities of the $988 million principal amount of ARCO's 9%
Exchangeable Notes due September 15, 1997, and a decrease in short-term
investments. At maturity, holders of the 9% Exchangeable Notes will receive
shares of Lyondell common

principal amount of the Notes.

     At December 31, 1996, ARCO had unused committed bank credit facilities
totaling $3.1 billion and ARCO Chemical had an unused bank credit facility
totaling $300 million. Vastar had an unused revolving credit facility totaling
$1.1 billion.

     During 1996, two projects were begun that could lead to growth in ARCO's
exploration and production operations.  ARCO entered into a joint venture with
Russia's largest oil company, LUKOIL, to pursue projects in the Commonwealth of
Independent States.  The joint venture entity, LUKARCO, of which ARCO owns 46%
and LUKOIL owns 54%, may invest up to $5 billion in various projects over the
next 18 years; ARCO has agreed to provide most of the financing to LUKARCO.  The
first investment will be in the Caspian Pipeline Consortium, a $2 billion 900-
mile pipeline project, of which LUKARCO will hold a 12.5% interest.

     ARCO also entered into a joint venture to produce and upgrade heavy oil
from the Orinoco region of Venezuela. The initial $2 billion phase of the
project, of which ARCO will hold a 30% interest, is expected to be operational
by 2001.

Capital Expenditures

     ARCO's 1997 capital spending program includes $3.4 billion for additions to
fixed assets, which includes spending for the Rhourde El Baguel, Wiriagar and
Alpine projects and a polypropylene project at the Los Angeles refinery.

     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. In addition, the status of negotiations with foreign sovereign
governments and third parties and approvals by foreign governments may also
affect the timing of 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 future financings.

Environmental Matters

     ARCO is subject to federal, state and local environmental laws and
regulations that require the Company to remove or mitigate the effect on the
environment of the disposal or release of certain chemical, mineral and
petroleum substances at various sites.  ARCO is currently participating in
environmental assessments and cleanups at numerous sites under these laws and
may in the future be involved in additional environmental assessments and
cleanups.

     The amount accrued represents the estimated undiscounted costs that ARCO
will incur to complete the remediation of sites with known contamination. In

uncertainty regarding ARCO's ultimate share of costs at various sites), it is
possible that actual costs could exceed the amount accrued by as much as $600
million.

ARCO's operating expenses 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 $230 million per year.  See Notes 3 and 13 to Consolidated
Financial Statements regarding environmental matters.

     In addition to the provision for environmental remediation costs, $950
million has been accrued for the estimated cost, net of salvage value, of
dismantling facilities as required by contract, regulation or law, and for the
estimated costs of restoration and reclamation of land associated with such
facilities.

Risk Management

     To minimize the effects of interest rate and foreign currency fluctuations,
ARCO enters into the following transactions using derivatives: 1) foreign
currency forward, option and swap contracts; 2) interest rate swaps; and 3)
financial futures contracts and over-the-counter Treasury options which are
limited to investment portfolio hedging, alteration of portfolio duration and
changing asset mix.

     ARCO and its subsidiaries also engage in hedging strategies involving
forward and futures contracts, swaps and options covering part of its natural
gas and crude oil production to minimize the effects of commodity price
fluctuations.  As of December 31, 1996, Vastar had entered into a series of
commodity swaps and natural gas price collar agreements covering approximately
373 million cubic feet per day (mmcfd) of its natural gas production in the
first quarter 1997 and 260 mmcfd in the second through fourth quarters 1997.

     Commodity swaps covering approximately 125 mmcfd and 150 mmcfd of Vastar's
natural gas production for 1997 and 1998, respectively, were at an average price
of $1.92 per thousand cubic feet (Mcf) and $2.07 per Mcf, respectively (on a
Henry Hub basis).  Another series of commodity swaps, covering approximately 115
mmcfd of its natural gas production in the first quarter 1997 and 85 mmcfd in
the second through fourth quarters 1997, were at an average price of $2.15 per
Mcf during the first quarter 1997 and $1.82 per Mcf (on a Henry Hub basis)
during the period April 1, 1997 through December 31, 1997.  The natural gas
price collar agreements, covering an additional 133 mmcfd of its natural gas
production in the first quarter 1997 and 50 mmcfd in the second through fourth
quarters 1997, were at prices between $2.37 and $2.75 per Mcf during the first
quarter 1997 and $2.07 and $2.33 per Mcf, (on a Henry Hub basis) during the
period April 1, 1997 through December 31, 1997.  Vastar's 1996 natural gas
production was 871.6 mmcfd.

     The Company uses simple, non-leveraged derivative instruments that are
placed with major institutions whose creditworthiness is continually monitored.
Risk management strategies are reviewed and approved by senior management before
being implemented. Policies limit the maximum amount of positions that can be
taken in any given instrument.

                        INDEPENDENT ACCOUNTANTS' REPORT
 
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, 1996 and 1995, and the related
consolidated statements of income, changes in stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1996 and
the related financial statement schedule listed in the index on page 37 of
this Form 10-K. These financial statements and financial statement schedule
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements and financial statement
schedule 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, 1996 and 1995, and the consolidated
results of its operations and its cash flows for each of the three years in
the period ended December 31, 1996, in conformity with generally accepted
accounting principles. In addition, in our opinion, the financial statement
schedule referred to above, when considered in relation to the basic financial
statements taken as a whole, presents fairly, in all material respects, the
information required to be included therein.

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 and Vastar Resources, Inc., of which ARCO owned
82.7% and 82.3% of the outstanding shares, respectively, at December 31, 1996.
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% and for
other ventures and partnerships in which less than a controlling interest is
held.

Cash Equivalents

  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.  Cash equivalents are stated at cost,
which approximates fair 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 the unit-of-
production or 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 value is included in current income. Upon disposal of assets depreciated
on a group basis, unless unusual in nature or amount, residual cost less salvage
value 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 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 and the amount of ARCO's liability in consideration of
the liability and financial wherewithal of other responsible parties.  Estimated
liabilities are not discounted to present value.

Stock-based Compensation

  Employee stock options are accounted for under the intrinsic-value-based
method prescribed by Accounting Principles Board Opinion (APB) No. 25.

Earned per Share

  Earned per share is based on the average number of common shares
outstanding during each period including common stock equivalents that consist
of certain outstanding options and all outstanding convertible securities.

Use of Estimates

  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Research and Development

  Expenditures for research and development totaled $106 million, $104 million
and $109 million for the years ended December 31, 1996, 1995 and 1994,
respectively.

Reclassifications

  The amounts for 1995 and 1994 reflect the exclusion from revenue and expenses
of excise taxes collected on behalf of the U.S. and various states and
reclassifications of delivery and other expenses from selling, general and
administrative expenses to operating expenses to conform with current
classifications. Certain other previously reported amounts have been restated to
conform to classifications adopted in 1996.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 2  Unusual Items

  During 1994, ARCO announced a restructuring program under which approximately
2,400 positions were to be eliminated.  The program covered all operating units,
excluding Lower 48 oil and gas operations, along with the corporate
headquarters.  In 1994, ARCO provided as unusual items $347 million before tax,
consisting primarily of personnel costs (pension enhancements, severance and
other ancillary costs) associated with the terminations.  In 1996, $26 million
was recorded as an unusual item to adjust reserves from the previously estimated
amounts.

  The following summarizes the final costs related to the program:

(a)  Enhanced pension benefits to be paid from assets of qualified pension plans
     after retirement of recipient.

(b)  Enhanced non-qualified pension benefits and postretirement medical and life
     insurance benefits. Benefits will be paid after retirement over the life of
     the recipient.

(c)  Severance and other ancillary benefits paid from Company funds.

  As of December 31, 1996, all of the accrued short-term benefits have been
paid.

Note 3  Accounting Changes

  In October 1996, the Accounting Standards Executive Committee issued Statement
of Position (SOP) 96-1, "Environmental Remediation Liabilities." SOP 96-1
requires adoption of its provisions for fiscal years beginning after December
15, 1996.  The provisions include standards affecting the measurement,
recognition and disclosure of environmental remediation liabilities.  The effect
of initially applying the provisions of SOP 96-1 will be reported as a change in
accounting estimate in the period adopted.  ARCO has not yet had sufficient time
to evaluate the impact of the provisions of SOP 96-1.

  In the fourth quarter of 1995, ARCO adopted Statement of Financial Accounting
Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of."  The effect of adopting SFAS No.
121 resulted in a charge of $12 million after tax to 1995 net income.

  Effective January 1, 1994, ARCO adopted SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities," which requires investments to be
carried at fair value, unless they are considered held-to-maturity securities.
The effect of adopting SFAS No. 115 had no impact on 1994 net income.

Note 4  Public Offering of Vastar Common Stock

  In September 1993, ARCO established Vastar Resources, Inc., a wholly owned
subsidiary of ARCO.  Effective October 1, 1993, ARCO conveyed to Vastar
beneficial title to certain producing properties together with certain developed
and undeveloped acreage.  Vastar is primarily engaged in the exploration for and
the development, production and marketing of natural gas.

  In July 1994, Vastar completed an initial public offering of 17,250,000 shares
of its common stock at $28 per share.  ARCO recognized an after-tax gain of $273
million from this transaction.

Note 5  Segment Information

  ARCO operates primarily in the Resources (upstream) and Products (downstream)
segments.  The Resources segment includes worldwide exploration and production
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, primarily from the North Slope of
Alaska; the marketing and transportation of petroleum products in the West Coast
region of the United States; and the worldwide manufacture and sale of chemical
products, including propylene oxide and derivatives, styrene monomer, and methyl
tertiary butyl ether.

  Segment information for the years ended December 31 was as follows:

Note 6  Inventories

  Inventories are recorded when purchased, produced or manufactured and are
stated at the lower of cost or market.  In 1996, approximately 86% 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 comprised the following categories:

Note 7  Investments

  At December 31, 1996 and 1995, investments in debt securities were primarily
composed of U.S. Treasury securities and corporate debt instruments. Maturities
generally ranged from two days to 22 months. These investments were principally
included in short-term investments. ARCO's investments in LUKOIL common stock
and Zhenhai Refining and Chemical Company common stock and convertible bonds
were included in other investments and long-term receivables. At December 31,
1996, all investments were classified as available-for-sale (AFS); there were no
investments considered held-to-maturity (HTM). AFS investments were reported at
fair value, with unrealized holding gains and losses, net of tax, reported in a
separate component of stockholders' equity.

 The following summarizes investments at December 31:

Note 9  Short-term Borrowings and Bank Credit Facilities

  Notes payable consist primarily of commercial paper issued to a variety of
financial investors and institutions and any amounts outstanding under ARCO or
ARCO Chemical credit facilities.  The weighted average interest rate on notes
payable outstanding at December 31, 1996 and 1995, was 5.7% and 6.3%,
respectively.

  In 1996, ARCO and certain wholly owned subsidiaries had committed bank credit
facilities of approximately $3.1 billion.  At December 31, 1996, there were no
borrowings under these committed facilities.

  ARCO Chemical maintains its own credit facility, not guaranteed by ARCO, under
which it may borrow up to $300 million.  At December 31, 1996, there were no
borrowings against this credit facility.

  At December 31, 1996, ARCO had unused letters of credit totaling approximately
$275 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

  In the fourth quarter of 1996, Vastar established a $1.1 billion Commercial
Paper Program for issuance of unsecured notes with maturities of up to 270 days
from the date of issue.  Vastar has agreed to maintain credit lines sufficient
to support payment on the notes.

  In 1996, Vastar consolidated existing unsecured revolving credit agreements
into a single facility.  The commitment under this facility totaled $1.1 billion
and expires March 29, 2001.  At December 31, 1996, the facility was unused.  The
credit facility is not guaranteed by ARCO.  The agreement contains covenants,
the most restrictive of which require Vastar to maintain minimum levels of
tangible stockholders' equity and certain financial ratios and restrict
encumbrance of assets.

  In August 1994, ARCO sold 39.9 million 9% Exchangeable Notes (Notes), due
September 15, 1997, at an issue price of $24.75 per note.  At maturity of the
Notes, holders will receive, in exchange for the principal amount, shares of
Lyondell stock, or at ARCO's option, cash with an equal value.  The number of
shares or the amount of such cash will be determined using a formula based on
the price of Lyondell common stock at the maturity of the Notes.

  ARCO periodically enters into interest rate swap agreements with the objective
of managing interest rate risk by converting the interest rate on variable rate
debt to a fixed rate.  The fixed rate is accrued and charged to interest expense
through the term of the interest rate swap agreement.  All interest rate swaps
are intended to be held until maturity.  At December 31, 1996, ARCO Chemical had
outstanding interest rate swaps on two loans of 150 million Dutch guilders each
(approximately $173 million in total) due in 1997.  Both swaps mature when the
related debt becomes due. The swaps effectively changed the loans' floating
interest rates to fixed rates of 5.7% and 6.7%, respectively.

  At December 31, 1996 and 1995, approximately $230 million and $365 million,
respectively, of long-term debt was denominated in foreign currencies. 

  No material amounts of long-term debt are collateralized by ARCO assets.

Note 12  Financial Instruments and Fair Value

  ARCO does not hold or issue financial instruments for trading purposes.

  ARCO enters into various types of foreign currency forward, option and swap
contracts.  Foreign currency forward and option contracts are used to minimize
foreign exchange exposures associated with U.S. dollar-denominated debt issued
by a foreign subsidiary, anticipated foreign currency commitments and
anticipated future cash flows from overseas operations.  Foreign currency swap
contracts are used to minimize foreign exchange exposures related to foreign-
denominated intercompany debt with maturities exceeding one year.

  At December 31, 1996, the notional amounts of foreign currency contracts
outstanding (principally involving European currencies and Australian dollars)
were approximately $804 million, with various maturities ranging from 1997 to
2000.  At December 31, 1995, the notional amounts of foreign currency contracts
outstanding were approximately $960 million.

  Gains and losses on foreign currency forward contracts covering anticipatory
cash flows are recognized currently as other income or expense.  Gains and
losses on foreign currency swaps associated with intercompany debt are
recognized currently in income and offset foreign exchange gains and losses on
the underlying intercompany loans.  Gains and losses on other foreign currency
contracts are generally deferred and offset the transactions being hedged.

                                      48

                                                                            ARCO

  ARCO periodically enters into interest rate swaps to manage interest rate
risk. Interest rate swaps are used in conjunction with debt (see Note 10).

  ARCO also uses various hedging arrangements to manage the exposure to price
risk for future natural gas and crude oil transactions.  Gains and losses
resulting from these transactions are deferred and included in other assets or
accrued liabilities until realized in sales and other operating revenues as the
physical production required by the contracts is delivered.  During 1996, Vastar
entered into a series of natural gas swap and price collar agreements which at
December 31, 1996, covered 288 million cubic feet per day of its 1997 natural
gas production and 150 million cubic feet per day of its 1998 natural gas
production.  These swap agreements will serve as hedges which secure prices on
these volumes at an average price of $1.99 per thousand cubic feet for 1997 and
$2.07 for 1998 (on a Henry Hub basis).

  At December 31, the carrying value and estimated fair value of ARCO's
financial instruments are shown as assets (liabilities) in the table below:

</TABLE>

  All derivative instruments are off-balance-sheet instruments; however, net
receivable or payable positions related to derivative instruments are carried on
the balance sheet.

  Short-term investments are carried at fair value.  The fair value of notes
payable approximates carrying value due to its short-term maturities.  Equity
method investments and other investments and long-term receivables were valued
at quoted market prices if available.  For unquoted investment securities, the
reported fair value was estimated on the basis of financial and other
information.  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.  The fair value of
foreign currency contracts and interest rate swaps represented the amount to be
exchanged if the existing contracts had been settled at year end and was
estimated based on market quotes.

  ARCO is exposed to credit risk in the event of nonperformance by the
counterparties. ARCO does not generally require collateral or other security to
support these financial instruments.  The counterparties to these instruments
are major institutions deemed creditworthy by ARCO; ARCO does not anticipate
nonperformance by the counterparties.

Note 13  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.

  Following the March 1989 EXXON VALDEZ oil spill, numerous lawsuits seeking
compensatory and punitive damages and injunctions were filed by the State of
Alaska, the United States and private plaintiffs against Exxon, Alyeska Pipeline
Service Company (Alyeska) and Alyeska's owner companies (including ARCO, which
owns approximately 22%).  Alyeska and its owner companies have settled the civil
damage claims by federal and state governments and the lawsuits by private
plaintiffs.  Certain issues relating to the liability for the spill remain
unresolved between the Exxon companies, on the one hand, and Alyeska and its
owner companies.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

  ARCO and former producers of lead pigments have been named as defendants in
cases filed by a municipal housing authority, three purported classes and
several individuals seeking damages and injunctive relief as a consequence of
the presence of lead-based paint in certain housing units.  ARCO is also the
subject of or party to a number of other pending or threatened legal actions.

  The State of Montana is seeking recovery from ARCO of $764 million based on
alleged injuries to natural resources resulting from ARCO's mining and mineral
processing businesses formerly operated by Anaconda, ARCO's predecessor in
Montana.  ARCO is contesting this demand.

  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.  ARCO may in the future be involved in
additional environmental assessments and cleanups.  The amount of such future
costs will depend on such factors as the unknown nature and extent of
contamination, the unknown timing, extent and method of remedial actions which
may be required and the determination of ARCO's liability in proportion to other
responsible parties.  In addition, environmental loss contingencies include
claims for personal injuries allegedly caused by exposure to toxic materials
manufactured or used by ARCO.

  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, 1996, the environmental remediation
accrual was $577 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 environmental remediation accrual 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, sites associated with discontinued operations and
sites formerly owned by ARCO.  ARCO has been named a potentially responsible
party (PRP) for 117 sites.  The number of PRP sites in and of itself is not a
relevant measure of liability because the nature and extent of environmental
concerns varies by site and ARCO's share of responsibility varies from sole
responsibility to very little responsibility.  ARCO reviews all PRP sites, along
with other sites as to which no claims have been asserted, in estimating the
amount of the accrual.  ARCO's future costs at these sites could exceed the
amount accrued by as much as $600 million.

  Approximately 45% of the reserve related to sites associated with ARCO's
discontinued operations, primarily mining activities in the states of Montana,
Utah and New Mexico.  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 10% of the total accrual.
Substantially all amounts accrued 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 third parties.  Many of these
claims have been resolved.  ARCO has neither recorded any asset nor reduced any
liability in connection with unresolved claims.

  Although any ultimate liability arising from any of the matters described
herein 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

<PAGE>

                                                                            ARCO

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
statements.

  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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 15  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 accrues pension costs based on an
actuarial valuation for each plan and funds the plans through contributions to
trust funds that are kept apart from Company funds.

  ARCO's assumptions used as of December 31 in determining the pension cost and
pension liability were as follows:

Note 16  Other Postretirement Benefits

  ARCO and its subsidiaries sponsor defined postretirement benefit plans which
provide other postretirement benefits to substantially all employees who retire
with ARCO having rendered the required years of service, and to their spouses
and eligible dependents.  Health care benefits are provided primarily through
comprehensive indemnity plans or health maintenance organizations (HMO), as
chosen by the employee.  Beginning January 1, 1997, ARCO will pay for the cost
of the benchmark HMO with employees responsible for the differential cost, if
any, of their selected option.  Previously, ARCO paid approximately 80% of the
cost of a comprehensive indemnity plan.  This change resulted in the
unrecognized prior service benefit reflected below.  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 has the right to modify the plans at any time.

  ARCO's current policy is to fund the cost of postretirement health care and
life insurance plans on a pay-as-you-go basis.

  ARCO accrues postretirement benefit costs based on actuarial calculations for
each plan. Net postretirement benefit costs for the years ended December 31
included the following:

  In addition to the cost above, in 1994 ARCO recorded $24 million before tax as
additional postretirement benefit expense in connection with work force
reductions.

and the accumulated postretirement benefit obligation (APBO) 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 9% for
1995 and 1996, 7% for 1997 to 2001, and 5% thereafter.  The assumed trend rate
for 1994 was 10% to 1996; 8% for 1997 to 2001, and 6% thereafter.  The effect of
a one-percentage-point increase in the assumed trend rate would increase the
APBO as of December 31, 1996, by approximately $57 million, and the aggregate of
the service and interest cost components of net annual postretirement benefit
cost by approximately $5 million.

  The plans' combined postretirement benefit liability at December 31 was as

granted.  The pro forma impact to both net income and earnings per share from
calculating compensation expense consistent with the fair value method under
SFAS No. 123 was not material for the years ended December 31, 1996 and 1995.

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>

  Included in ARCO's reserves are 100% of the reserves of Vastar, a consolidated
subsidiary of which ARCO owned 82.3% at December 31, 1996. Vastar's reserves
comprised 5% and 47% of U.S. petroleum liquids and natural gas reserves,
respectively, at December 31, 1996.

  ARCO owns shares of common stock of LUKOIL, a Russian oil company,
representing approximately 8% of LUKOIL's total equity. As of January 1, 1996,
LUKOIL reported western Siberia reserves of approximately 7.9 billion barrels of
oil and 1.5 trillion cubic feet of natural gas. Reserve information subsequent
to that date is not presently available. Eight percent of those reserves would
be 634 million barrels and 122 billion cubic feet, respectively. LUKOIL reserves
are not included in ARCO's totals.

  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.

 The changes in proved reserves for the years ended December 31 were as follows:

</TABLE>

  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 14% of petroleum liquid proved reserves.

  Significant changes in 1996 related to a production-sharing agreement signed
with the Algerian national oil company and the discovery of the Alpine field in
Alaska.

  The sale of natural gas from the North Slope of Alaska, other than that 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 included in ARCO's reserves.

  ARCO continues to study various options for marketing North Slope gas.
However, ARCO believes that market conditions continue to make implementation of
any large gas sales projects unlikely in the near 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 were as follows:

</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. Estimates of future net
cash flows presented do not represent management's assessment of future
profitability or future cash flows 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.

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

         COMPANY POLICY ON FINANCIAL COUNSELING & INDIVIDUAL INCOME TAX
                  SERVICE FOR EXECUTIVES IN SALARY GRADE 64E4


     2.  The Company will reimburse eligible executives in accordance with the
         following provisions for the services of the organizations they select:
        
         a.   Reimbursement for all financial counseling and individual income
              tax service rendered during the initial calendar year of the
              executive's participation under this policy will generally not
              exceed $5,800.
 
         b.   Reimbursement for all financial counseling service and individual
              income tax service during the calendar year of a participating
              executive's termination will generally not exceed $5,800.

         c.   Reimbursement for follow-up financial counseling and individual

              preceding the executive's termination will generally not exceed
              $4,200.

         d.   Any allowance unused in a calendar year may be carried forward to
              the next calendar year for use during that period as necessary.
              However, no more than the maximum allowance for a given year is
              subject to carry forward, i.e., $5,800 for the initial year and
              $4,200 for succeeding years.

         e.   If necessary, the allowance for the year following the current
              year may be carried back to cover expenses in the current year
              assuming the executive's expected continued eligibility. No more
              than one year forward is available for carry back. If an executive
              has received reimbursement under the carry back provisions of the
              plan at the time of termination of employment, the Company may, at
              its discretion, request reimbursement from the executive for any
              such amount.

              services provided in preparation/updating of personal wills and

              individual income tax service for that year.

              policy, an allowance of $950 will apply with respect to

         payment of the service organization's invoices.

     5.  Reimbursements will be grossed up in consideration of federal and state
         income taxes.

     an eligible executive should use such services, and will not encourage or
     discourage use of any particular organization by an eligible executive.

     receipt thereof, any eligible executive shall release and discharge the
     Company and any employee or other person who furnishes such information

     said applying executive may suffer as a consequence of receipt or use of
     such information.

         i.   If an executive's employment with the Company ceases other than by
              retirement with an immediate retirement allowance, death, or by
              agreement with the Company, reimbursement will not be made for any

              executive after the date employment terminates.

     3.  Brokers' fees or promoters' fees are not reimbursable.

     4.  To obtain reimbursement under this policy, a participating executive
         will forward the service organization's invoices with covering
         memorandum to the Manager, Executive Relations. The Company's check
         will be payable to the executive. The executive is responsible for
         payment of the service organization's invoices.

         income taxes.

     6.  The total reimbursement made by the Company will be reported to the

         rates at the time payment is made.

     an eligible executive should use such services, and will not encourage or
     discourage use of any particular organization by an eligible executive.

     receipt thereof, any eligible executive shall release and discharge the
     Company and any employee or other person who furnishes such information
     from any and all liability and responsibility for loss or damage which
     said applying executive may suffer as a consequence of receipt or use of
     such information.

         COMPANY POLICY ON FINANCIAL COUNSELING & INDIVIDUAL INCOME TAX
             SERVICE FOR EXECUTIVES IN SALARY GRADES 64E0 AND 64E1


     2.  The Company will reimburse eligible executives in accordance with the
         following provisions for the services of the organizations they select:
        
         a.   Reimbursement for all financial counseling and individual income
              tax service rendered during the initial calendar year of the
              executive's participation under this policy will generally not
              exceed $12,000.
 
         b.   Reimbursement for all financial counseling service and individual
              income tax service during the calendar year of a participating
              executive's termination will generally not exceed $12,000.

         c.   Reimbursement for follow-up financial counseling and individual
              income tax services in any calendar year other than the initial
              calendar year of participation or the calendar year immediately
              preceding the executive's termination will generally not exceed
              $8,000.

         d.   Any allowance unused in a calendar year may be carried forward to
              the next calendar year for use during that period as necessary.
              However, no more than the maximum allowance for a given year is
              subject to carry forward, i.e., $12,000 for the initial year and
              $8,000 for succeeding years.

         e.   If necessary, the allowance for the year following the current
              year may be carried back to cover expenses in the current year
              assuming the executive's expected continued eligibility. No more
              than one year forward is available for carry back. If an executive
              has received reimbursement under the carry back provisions of the
              plan at the time of termination of employment, the Company may, at
              its discretion, request reimbursement from the executive for any
              such amount.

         f.   A one-time allowance of up to $3,000 for reimbursement of legal
              services provided in preparation/updating of personal wills and
              trusts is available. However, if an eligible executive relocates
              to a different state, an additional allowance of up to $1,500 for
              reimbursement of legal services provided in updating personal
              wills and trusts to reflect the laws of the new state is
              available.

         g.   The first year allowance of $12,000 will also be available to
              change counseling organizations one time during the entire
              eligibility period at the executive's discretion, not including
              the provisions of f. above.  This allowance would include
              individual income tax service for that year.

         h.   If an executive terminates or dies while a participant under this
              policy, an allowance of $1,550 will apply with respect to
              individual income tax returns for the last calendar year in which
              the executive was in the active service of the Company.
