ITEMS 1. AND 2. BUSINESS AND PROPERTIES

                                  The Company

  The company began operations in 1866 as the Atlantic Petroleum Storage
Company. The company's present name, Atlantic Richfield Company (ARCO), was
adopted in 1966 after Richfield Oil Corporation was merged into the company.
Sinclair Oil Corporation was merged into ARCO in 1969. ARCO acquired The
Anaconda Company in 1977. ARCO became a Delaware corporation in 1985. ARCO
acquired Union Texas Petroleum Holdings, Inc. (UTP) in 1998. On April 18,
2000, ARCO merged with a subsidiary of BP Amoco p.l.c. (BP), which indirectly
holds all of the outstanding common stock of ARCO. In September 2000,
following ARCO's purchase of the publicly held shares of Vastar Resources,
Inc. (Vastar), Vastar merged with a subsidiary of ARCO, bringing ARCO's
ownership in Vastar to 100%.
  ARCO's principal executive offices are currently at the ARCO Center, 333
South Hope Street, Los Angeles, California 90071 (Telephone 213-486-3511).
  ARCO is a global oil and gas enterprise operating in two segments,
exploration and production and refining and marketing. Its upstream
exploration and production operations are focused primarily in the Gulf of
Mexico and the Midcontinent in the United States, the United Kingdom North
Sea, Indonesia, China and Algeria. ARCO's downstream refining and marketing
operations are located primarily in the western United States. These include
two refineries, branded consumer marketing outlets in six western states and
British Columbia, Canada, and supporting pipelines and terminals.

               ARCO's New Structure following Acquisition by BP

  As discussed in the following section, as of April 18, 2000, ARCO became
part of the BP Group, a worldwide integrated oil and gas and chemical
business. As part of the BP Group, the ARCO businesses have been structured
into business units, some of which were combined with other businesses from
the BP Group. The operations within the BP Group are managed through four main
businesses, Exploration and Production, Gas and Power, Refining and Marketing
and Chemicals. Gas and Power and Chemical operations are not material for
ARCO.
  The financial position and results of operations of ARCO should be
understood in the context of this relationship.
  The financial statements of ARCO reflect the historical costs to the
previous shareholder group and accordingly, do not reflect any purchase
accounting adjustments related to the acquisition of ARCO by BP.

                   BP Combination; Change of Control of ARCO

  On April 18, 2000, the combination of BP and ARCO was completed by the
merger of Prairie Holdings, Inc (a subsidiary of BP) with and into ARCO,
pursuant to the terms of the merger agreement dated March 31, 1999, as amended
through March 27, 2000 (Merger Agreement). Pursuant to the Merger Agreement,
each share of outstanding common stock of ARCO (except for any such shares
owned by BP, ARCO or any subsidiary of BP or ARCO) was converted into the
right to receive 1.64 BP American Depositary Shares (ADSs) or, subject to the
timely receipt of elections therefor, 9.84 BP Ordinary Shares. In addition,
the outstanding ARCO common stock was delisted from the New York Stock
Exchange and other exchanges on which it had been listed. In connection with
the merger, on April 18, 2000, ARCO issued 324,711,290 new shares of common
stock to BP. Later on April 18, 2000, BP transferred all such shares to
BP America Inc., a wholly owned subsidiary of BP, so that BP owns indirectly
all of the currently outstanding common stock of ARCO. As the holder of all
the outstanding common stock of ARCO, none of which is publicly traded, BP is
the controlling shareholder of ARCO.

                                       1


  On April 18, 2000, in connection with the combination of ARCO and BP,
PricewaterhouseCoopers LLP (PwC) resigned as ARCO's independent accountants.
Ernst & Young, L.L.P., who also act as independent auditors for BP, were
appointed as ARCO's independent auditors on April 27, 2000.
  ARCO's outstanding shares of $2.80 and $3.00 Preference Stock remained
listed on the New York Stock Exchange. Pursuant to the Merger Agreement, each
share of $2.80 Preference Stock became convertible into 7.872 ADSs and each
share of $3.00 Preference Stock became convertible into 22.304 ADSs. BP has
fully and unconditionally guaranteed the payment of dividends on, the
redemption price and the liquidation preference that may become payable in
respect of shares of both classes of Preference Stock.
  Following the merger, as a result of the number of holders of the Preference
Stocks, ARCO remained a reporting company within the meaning of the Securities
and Exchange Act of 1934 (1934 Act). As disclosed below, on March 28, 2001
ARCO issued a notice of redemption for all of the outstanding shares of these
two classes of Preference Stock. Following the redemption date, ARCO will
cease to be a reporting company under the 1934 Act.
  Holders of the Preference Stocks and others may obtain copies of the BP
Report on Form 20-F for the year ended December 31, 2000 by telephone from BP
Group Shareholder Services, toll free at 1-800-638-5672.
  Included in the merger agreement was a provision requiring BP to keep in
place for two years following the merger ARCO's change of control severance
programs. The benefits associated with those programs resulted in ARCO
recording a charge of $560 million for the year ended December 31, 2000 for
ARCO executives and employees who have been or will be terminated prior to
April 18, 2002 as a result of the merger and related asset sales.
  Other merger costs related to facilities closures with no future economic
benefit, payments to legal and investment consultants in connection with
negotiation and consummations of merger, and shutdown costs related to UK and
certain other overseas locations.

               Sale of ARCO's Businesses Pursuant to FTC Mandate

  On March 15, 2000, pursuant to an understanding with the Federal Trade
Commission (FTC) in conjunction with its review of the acquisition of ARCO by
BP, ARCO entered into an agreement to sell its Alaskan businesses to Phillips
Petroleum Company (Phillips) for approximately $6.5 billion cash, subject to
purchase price adjustments (plus up to an additional $500 million based on the
price realized on post-closing production). Under the purchase and sale
agreement, which was amended on April 6, 2000, ARCO agreed to sell all of the
outstanding shares of ARCO Alaska, Inc., together with certain other
subsidiaries of ARCO engaged principally in the operation of ARCO's Alaskan
businesses, along with certain pipeline and marine assets associated with the
transport of Alaskan crude oil.
  In the second quarter of 2000 ARCO completed the sale of its Alaskan
operations, comprising oil and gas production, crude oil marine transportation
and related crude oil inventory, for proceeds totaling approximately
$6.2 billion and realized an after-tax gain of approximately $1.8 billion. The
net book value of those assets at the time of the sale was approximately $3.2
billion.
  In the third quarter of 2000 ARCO completed the sale of its Alaskan pipeline
operations, thereby completing the sale of all Alaskan operations mandated by
the FTC in obtaining approval for the combination of ARCO and BP. ARCO
received proceeds of $308 million and recorded an after-tax loss of
$34 million. See Note 4 of Notes to Consolidated Financial Statements.
  In the third quarter of 2000 ARCO also completed the sale of the remaining
pipeline assets mandated by the FTC. On July 20, 2000, ARCO sold certain
Midcontinent pipeline assets for $314 million. See Note 5 of Notes to
Consolidated Financial Statements.

                                       2


               Delisting and Retirement of ARCO Debt Securities

  On August 13, 2000, ARCO terminated the registration under the Securities
Act of 1933 of all of its outstanding publicly traded debt securities. In
connection with the deregistration, the three classes of debt securities that
had been listed on the New York Stock Exchange were delisted.
  On November 29, 2000, ARCO made a cash tender offer for up to $1,045,790,000
of its outstanding noncallable debt securities having interest rates ranging
from 8 1/4% to 9 7/8% and maturity dates ranging from March 1, 2016 to March
1, 2032. Through the expiration date of December 8, 2000, ARCO purchased a
total of $1,045,790,000 of debt securities pursuant to the cash tender offer.
Subsequent to the closing of the tender offer, ARCO repurchased an additional
$14 million of outstanding debt securities on the open market.

                   Merger Agreement between ARCO and Vastar

  ARCO and Vastar (a subsidiary of which ARCO owned 81.9%) entered into a
merger agreement, dated May 24, 2000. The agreement provided for the
acquisition by ARCO of Vastar's publicly held minority stockholding at a price
of $83 per share. On September 15, 2000, Vastar's common stock minority
shareholders approved the merger agreement between ARCO and Vastar. Following
the approval, 18,252,609 shares were purchased by ARCO at a price of $83 per
share for a total purchase price of $1,618 million, including costs related to
the transaction. Vastar became a 100% owned subsidiary of ARCO.

                     Redemption of ARCO Preference Stocks

  On March 28, 2001, ARCO called for the redemption of all of the outstanding
shares of its $3.00 Preference Stock and its $2.80 Preference Stock on April
27, 2001 (Redemption Date). As of December 31, 2000, there were 35,437 shares
of $3.00 Preference Stock and 402,665 shares of $2.80 Preference Stock
outstanding.
  Upon redemption, for each share of $2.80 Preference Stock redeemed, the
Company will pay to the holder, as required by the Company's Certificate of
Incorporation, the stated redemption price of $70.00 per share, together with
the amount of accrued and unpaid dividends on each such share (whether or not
earned or declared) to the Redemption Date, plus a voluntary supplemental cash
payment in the amount, if any, required to cause the total per share cash
payment to be received by such holder ($2.80 Redemption Payment), to equal the
market value of 7.872 BP ADSs. On or prior to April 20, 2001 (Conversion
Deadline), each share of $2.80 Preference Stock is convertible into 7.872 BP
ADSs.
  Upon redemption, for each share of $3.00 Preference Stock redeemed, the
Company will pay to the holder, as required by the Company's Certificate of
Incorporation, the stated redemption price of $82.00 per share, together with
the amount of accrued and unpaid dividends on each such share (whether or not
earned or declared) to the Redemption Date, plus a voluntary supplemental cash
payment in the amount, if any, required to cause the total per share cash
payment to be received by such holder ($3.00 Redemption Payment), to equal the
market value of 22.304 BP ADSs. On or prior to the Conversion Deadline, each
share of $3.00 Preference Stock will be convertible into 22.304 BP ADSs.
  The market value of the BP ADSs will be determined by the average of the
last sale prices for a BP ADS on the New York Stock Exchange over the four
trading days ending on the last trading day prior to the Redemption Date.
  In accordance with the Company's Certificate of Incorporation, upon
redemption of both classes of Preference Stocks, the holders thereof will have
no interest in or claim against the Company or its agents other than the right
to receive the $2.80 or $3.00 Redemption Payment, as applicable, upon the
proper surrender of the shares of Preference Stock, subject to the conversion
right described above.
  No commission or other remuneration will be paid or given, directly or
indirectly, in connection with the conversion of Preference Stock into BP
ADSs.

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.
ARCO's various annual delivery obligations under these contracts are
substantially limited to producible reserves from specific fields.
  In the Lower 48, Vastar has various long-term natural gas sales commitments
under certain long-term gas marketing contracts with cogeneration facilities
pursuant to which Vastar delivered an average of 79 MMCFD in 2000. These long-
term contracts have an average remaining contract term of approximately
10 years. In 2000, the average price of

                                       5


gas sold under these contracts was approximately $2.74 per MCF. There have
been no instances in the last three years in which Vastar was unable to meet
any significant natural gas delivery commitment.

                       Refining and Marketing Operations

  ARCO's downstream operations primarily include its two refineries on the
West Coast and branded retail gasoline outlets in six western states and
British Columbia, Canada.
  ARCO's two U.S. petroleum refineries are the Los Angeles Refinery in Carson,
California and the Cherry Point Refinery near Ferndale, Washington. Both of
these refineries have easy access to major supply sources and major markets
through ocean-going tankers, pipelines and other transportation facilities.
  ARCO currently markets its gasoline under the ARCO(R) trademark. ARCO sells
its gasoline at ARCO branded retail outlets located in Arizona, California,
Nevada, Oregon, Utah and Washington, and in British Columbia, Canada. The
company currently has more than 1,700 branded retail outlets, which include
franchisee and company-operated am/pm(R) convenience stores and SmogPros(R)
Service Centers, along with traditional service stations. ARCO's am/pm
franchises, full scale convenience stores that also sell gasoline, make up
about 60% of the retail outlets. ARCO also sells gasoline to dealers and
resellers who do not use the ARCO brand in connection with retail sales.

     and the purchase and sale of petroleum products not manufactured by
     ARCO.


                             All Other Operations

  ARCO's other operations during 2000 comprised its pipeline operations in the
Lower 48 and its aluminum operations.

                                Capital Program

  ARCO's capital program includes spending for additions to fixed assets and
other capital expenditures. During 2000, the company spent approximately
$2.1 billion for additions to fixed assets.
  Future capital expenditures remain subject to business conditions affecting
the industry, as well as changes in environmental rules and regulations and
the tax laws.

                                    Patents

  ARCO owns numerous patents, many of which it makes generally available for
license to others in the petroleum industry. ARCO itself is a licensee under
certain patents that are available generally to the industry. ARCO's opera-
tions are not dependent upon any particular patent or patents or upon any ex-
clusive patent rights.

                                  Competition

  ARCO faces intense competition from a number of companies in all of its op-
erations. Many of its competitors are large and have substantial resources. No
single competitor dominates either of ARCO's operating segments.

                                Human Resources

  As of December 31, 2000, ARCO had approximately 11,200 full-time-equivalent
employees, of whom approximately 10% were represented by collective bargaining
agents.

                             Environmental Matters

Site Remediation

ARCO 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). These regulations require ARCO to do some or all
of the following:
  . Remove or mitigate the effects on the environment at various sites from
    the disposal or release of certain substances;
  . Perform restoration work at such sites; and
  . Pay damages for loss of use and non-use values.
Environmental liabilities include personal injury claims allegedly caused by
exposure to toxic materials manufactured or used by ARCO.
  ARCO is currently involved in environmental assessments and cleanups under
these laws at federal- and state- managed sites, as well as other clean-up
sites, including service stations, refineries, terminals, third party
landfills, former nuclear processing facilities, sites associated with
discontinued operations and sites that were formerly owned by ARCO or its
predecessors. This comprises 148 sites for which ARCO has been named a
potentially responsible party (PRP), along with other sites for which no
claims have been asserted. 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 responsibility varies from sole
responsibility to very little responsibility. Future costs depend on numerous
unknown factors such as:
  . Nature and extent of contamination;
  . Timing, extent and method of remedial action;
  . ARCO's proportional share of costs; and
  . Financial condition of other responsible parties.
The environmental remediation accrual is updated at least annually, and at
December 31, 2000, was $1,098 million.
  The amount accrued represents the estimated undiscounted costs that ARCO
will incur to complete the remediation of sites with known contamination. In
view of the uncertainties associated with estimating these costs (such as
differences of opinion between ARCO and various regulatory agencies with
respect to the appropriate method for remediating contaminated sites,
uncertainty as to the extent of contamination at various sites, and
uncertainty regarding ARCO's ultimate share of costs at various sites), it is
possible that actual costs could be significant. Although these costs might be
material to the results of operations in the period in which they are
recognized, ARCO does not expect that such costs will have a material effect
on ARCO's financial position or equity. See Note 19 of Notes to Consolidated
Financial Statements regarding environmental matters.
  Approximately 85% of the reserve relates to sites associated with ARCO's
discontinued operations. Another significant component relates to currently
and formerly owned or operated nuclear processing, and refining and marketing
facilities, and other sites that received wastes from these facilities. One
site represented 13% of the total accrual. No other site represented more than
8% of the total accrual. Substantially all amounts reserved are expected

                                       8


to be paid out over the next 10 years. ARCO is also the subject of certain
material legal proceedings described below under the caption
"Material Environmental Litigation."

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
Environmental Protection Agency (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 specifications for reformulated gasoline of the California Air
Resources Board (CARB), 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. To comply with federal EPA
standards for gasoline, the company has used the oxygenate methyl tertiary
butyl ether (MTBE) in making its reformulated gasoline. However, effective
January 1, 2003, the State of California has mandated that gasoline in
California may no longer include MTBE as the oxygenate component.
  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 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 $191 million per year. The company anticipates
environment-related capital expenditures of approximately $100 million and
$30 million for 2001 and 2002, 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 $150 million
per year. Cash payments for site remediation have averaged $145 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 $170 million per year.

                                       9


  In addition to the reserve for environmental remediation costs, the company
has also accrued, as of December 31, 2000, $312 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
asserted claims against ARCO for compensation for damage to natural
resources allegedly arising out of ARCO's or its predecessors' mining and
mineral processing activities. In addition, two tribes (Tribes) were granted a
limited form of intervention in Montana v. ARCO. The Tribes, as alleged
trustees, 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. These
matters were settled in part in 1999. Remaining for disposition are the
State's claims for $206 million of restoration damages at three sites.
  On June 23, 1989, the EPA filed a CERCLA cost-recovery action against ARCO,
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 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. The settlements in Montana v. ARCO,
described above, resolved the claims and counterclaims in U.S. v. ARCO
pertaining to one significant site and may provide a framework for possible
future settlement of the remaining claims. As part of U.S. v. ARCO, settlement
has been negotiated for claims and counterclaims concerning past and future
costs associated with the Rocker site, by which ARCO is to pay $3.4 million.
This is in settlement of federal government claims of $3.9 million for past
remediation and oversight costs, and an additional $0.9 million for future
costs. The settlement was filed with the court during August 2000.
  On April 26, 2000 the United States District Court for the Central District
of California issued a subpoena for production of records to the grand jury
regarding the Company's compliance with underground storage tank regulations
at retail gasoline facilities. On May 8, 2000, the United States District
Court for the Eastern District of California issued a similar subpoena. On May
8, 2000 the District Attorney of Stanislaus County, California informed the
Company that the California Regional Water Quality Control Board, Central
Valley Region and the Stanislaus County Department of Environmental Resources
had alleged that the Company had violated California statutes regarding
underground storage tanks, hazardous materials and unlawful business
practices. The Stanislaus District Attorney further advised, however, that no
decision had been made as to the filing of charges, pending discussions with
the Company. On May 17, 2000, the Los Angeles County Department of Public
Works informed the Company that it was investigating the Company's compliance
with underground storage tank regulations at certain of the Company's retail
gasoline facilities in Los Angeles County. On June 6, 2000, the California
Attorney General, pursuant to his statutory investigative powers, issued a
subpoena for the Company's records regarding underground storage tanks.
Moreover, the Company is in the process of conducting a comprehensive audit of
all of its underground storage tank facilities in California, Arizona, Nevada,
Oregon, Utah and Washington.
  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 (DOE)
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. On
April 4, 1997, ARCO was served with a new complaint making allegations

                                      10


similar to those already pending in the litigation, filed by six individual
Native Americans in the United States District Court for the Western District
of Washington, purportedly on behalf of classes of Native Americans living
near the Hanford Nuclear Reservation. The DOE has indicated that it will
indemnify ARCO and ARHCO with respect to this new action as well. This action
has been transferred to the United States District Court for the Eastern
District of Washington. On August 21, 1998, the court issued a ruling that, if
upheld on appeal, should result in the dismissal of ARHCO and ARCO from the
case.
  Approximately 200 lawsuits were filed in state and federal courts in Alaska
seeking compensatory and punitive damages arising out of the Exxon Valdez oil
spill in Prince William Sound in March 1989. Most of those suits named Exxon
(now ExxonMobil), Alyeska Pipeline Service Company (Alyeska), which operates
the oil terminal at Valdez, and the other oil companies which own Alyeska
(including ARCO Transportation Alaska, Inc., owned by ARCO until the FTC-
mandated sale to Phillips Petroleum in April 2000). Alyeska initially
responded to the spill until the response was taken over by Exxon. Alyeska and
its owners have settled all of the claims against them under these lawsuits.
Exxon has indicated that it may file a claim for contribution against Alyeska
(and its owner companies) for a portion of the costs and damages which it has
incurred.
  ARCO has been named as a defendant in a number of lawsuits involving the
manufacture and use of MTBE as a fuel additive and oxygenate. Several other
refiners of gasoline in the United States are defendants in some or all of
these cases. Lyondell Chemical Company, f/k/a ARCO Chemical Company, is a
defendant in many of these matters. There are potential issues regarding
indemnification between ARCO and Lyondell, which are unresolved. Generally,
these cases allege product liability, negligence and fraud. Plaintiffs allege
that MTBE is unreasonably dangerous and has contaminated groundwater,
potentially leading to contamination of private and public drinking water
supplies. They further allege that ARCO knew, or should have known, that MTBE
made gasoline more dangerous, fraudulently concealed this hazard, and promoted
the use of MTBE in spite of this risk. The cases are:
  South Lake Tahoe Public Utility District (STPUD) vs. ARCO, et al. (Superior
Court of the State of California In and For the County of San Francisco, Case
No. 999128, filed April 16, 1999) STPUD alleges that MTBE contamination in its
drinking water wells was caused by leakage from underground MTBE storage tanks
belonging to ARCO and the other defendants.
  Communities for a Better Environment (CBE) vs. ARCO, et al. (Superior Court
of the State of California In and For the County of San Francisco, Case No.
997103, Second Amended Complaint, filed June 29, 2000) CBE alleges that the
environment in California has been damaged by the introduction of MTBE into
gasoline. In addition to the legal theories outlined above, CBE includes an
action for violation of California's Unfair Business and Professional Code,
Section 17-200.
  City of Santa Monica vs. ARCO, et. al. (Superior Court of the State of
California In and For the County of San Francisco, Case No. 313004, filed June
19, 2000) Santa Monica alleges contamination of its water supply by a number
of leaking underground storage tanks, including one owned by ARCO.
  Millet vs. ARCO, et. al. (Superior Court of Cumberland County, Maine, Case
No. CV-98-367-P-H, filed October 7, 1998) A class action lawsuit brought by a
purported class of private well owners in the State of Maine alleging
potential or actual damage to their wells. Class certification was denied by
the trial court and that denial has been affirmed on appeal. The remaining
claims have been resolved for a nominal payment.
  Berisha vs. ARCO, et al. (United States District Court for the Southern
District of New York, Case No. 00 CIV 1898 [SAS], filed January 14, 2000) A
class action lawsuit brought by a purported class of private well owners in
the State of New York alleging potential or actual damage to their wells.
Multidistrict litigation (MDL) has been established in this court.
  Sutton Farms vs. ARCO, et. al. (United States District Court for the
Southern District of Florida, Case No. 00-3544, filed September 21, 2000) A
class action lawsuit brought in Miami, Florida by a purported class of

                                      11


private and commercial well owners in 34 states alleging potential or actual
damage to their wells. This matter has been transferred to the Berisha court
in New York for consolidated handling as part of the MDL.
  England v. ARCO, et al. (In the Circuit of the Third Judicial Circuit,
Madison County, Illinois, Case No. 00 L 000331, filed April 11, 2000) A class
action lawsuit brought in Madison County, Illinois by a purported class of
private well owners in 16 states alleging potential or actual damage to their
wells. This matter has been transferred to the Berisha court in New York for
consolidated handling as part of the MDL.
  No class has been certified in any of these cases.
  In January 1998, The Pinal Creek Group, consisting of Cyprus Miami Mining
Corporation, Inspiration Consolidated Copper Company ("Inspiration") and BHP
Copper Inc., f/k/a Magna Copper Company, filed an action for declaratory
relief, breach of contract and breach of the covenant of good faith and fair
dealing against their insurers for failure to provide defense and indemnity
coverage for environmental liabilities arising out of the Pinal Creek Site in
Arizona. The complaint estimates the cost to remediate the Pinal Creek site to
exceed $100 million. The action, CV-98-00530, is pending in the Superior Court
for the State of Arizona in and for the County of Maricopa. In February 1998,
that action was tendered to Atlantic Richfield Company ("ARCO") on behalf of
several insurers whom ARCO had agreed to defend, indemnify and hold harmless
in connection with such environmental liabilities as part of its settlements
with those insurers in the ARCO v. Aetna, et al., omnibus environmental
coverage action. The insurers with whom ARCO made such an agreement are
Travelers, Century Indemnity Company, successor to CCI Insurance Company,
successor to Insurance Company of North America, successor to Indemnity
Insurance Company of North America, and Continental Casualty Company. These
policies were issued to Anaconda, which merged with ARCO, and included
Inspiration as a named insured.

Environmental Matters Relating to International Operations

ARCO's international operations, which are primarily located in the
United Kingdom North Sea, Indonesia, China, and Algeria, are conducted in
accordance with internationally acceptable environmental standards and are
also subject to foreign laws covering environmental matters, as well as to
contractual obligations relating to dismantlement and abandonment. To date,
ARCO has not incurred any significant expenditures for environmental
remediation, is not involved in any environmental cleanup, and has not
reserved any amount for environmental remediation, relating to its operations
in the United Kingdom North Sea, Indonesia, China, and Algeria. The foreign
environmental laws and regulations have not had, and are not presently
expected to have, a material adverse effect on ARCO's financial results or
position.

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 19 of Notes to Consolidated Financial
Statements and "Environmental Matters."

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, City of New
York, et al. v. Lead Industries Association, et al. (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 sought 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 (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 sought punitive damages and attorney's fees. As a result of various court
rulings, the plaintiffs' only remaining claims are for fraud and restitution
and indemnity. Two stipulated dismissals have further narrowed the case. The
City of New York and the New York City Health and Hospitals Corporation
entered into a stipulated order dismissing with prejudice all of their pending
claims against ARCO and the other defendants. The remaining plaintiff, the
Housing Authority, then entered into another stipulated order dismissing its
claims as to all the Housing Authority properties except for two housing
projects.
  On November 25, 1998, ARCO (as successor to IS&R) was named as a defendant
in a purported class action suit, Sabater, et al. v. Lead Industries
Association, et al. (Case No. 25533/98), filed in the Supreme Court of the
State of New York for the County of Bronx by the mothers of four minor
plaintiffs. The complaint also names the LIA and eight former lead
pigment/paint manufacturers. The plaintiffs seek, on behalf of themselves and
a purported class of children age six and under residing in dwellings in the
City of New York containing or presumed to contain lead paint, unspecified
compensatory damages and injunctive relief from all defendants, including
orders requiring defendants to contribute to a court-administered fund to pay
for (i) notification to class members of the dangers of lead-based paint, (ii)
abatement of properties where class members reside and to pay for temporary
relocation during abatement, (iii) medical monitoring, including screening,
testing, diagnosing, and treating of class members, and (iv) attorney's fees.
The complaint alleges causes of action against the defendants for strict
product liability, conspiracy, concert of action, and enterprise and market
share liability.
  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, unspecified money
damages for injuries allegedly suffered from exposure to lead paint, punitive
damages, and an order requiring defendants to remove and abate all lead paint
applied to any building in Ohio. The suit names as defendants, in addition to
ARCO, the LIA and 16 companies alleged to have participated in the manufacture
and sale of lead pigments and paints and includes causes of action for strict
product liability, negligence, breach of warranty, fraud, nuisance,
restitution, negligent infliction of emotional distress, and enterprise,
market share and alternative liability.
  On September 20, 1999, ARCO (as successor to IS&R) was named by 11
homeowners as defendants in a purported class action suit filed in the Circuit
Court for Baltimore City, Maryland, Earl Cofield, et al. v. Lead Industries
Association, et al. (Case No. 24-C-99-004491). The amended complaint, which
also names 13 alleged former manufacturers of lead products, the LIA, and the
National Paint and Coatings Association, alleges causes of action for
negligent product design and failure to warn, supplier negligence, fraud and
deceit, conspiracy, concert of action, aiding and abetting, and strict product
liability. The plaintiffs seek, on behalf of themselves and a purported class
of

                                      13


over 10,000 people living in the State of Maryland whose pre-1978 residences
allegedly were contaminated with lead-based paint, unspecified compensatory and
punitive damages and injunctive relief, including orders requiring defendants
to pay for (i) notification to class members about the hazards of lead
pigments, (ii) abatement of residences where class members reside, (iii) a
public education campaign concerning the hazards of lead pigments, lead paint,
and lead poisoning, and (iv) attorney's fees.
  On October 12, 1999, ARCO (as successor to IS&R) was named as a defendant in
a lawsuit filed in Rhode Island Superior Court, Providence County by Rhode
Island Attorney General Sheldon Whitehouse, State of Rhode Island v. Lead
Industries Association, et al. (Case No. 99-5226). The complaint, which also
names seven former lead pigment manufacturers and the LIA, alleges causes of
action for public nuisance, violation of Rhode Island's Unfair Trade Practice
and Consumer Protection Act, strict liability, negligence, negligent and
fraudulent misrepresentations, civil conspiracy, unjust enrichment, indemnity
and equitable relief to protect children. The State of Rhode Island seeks
unspecified compensatory and punitive damages, funding for a public education
campaign concerning the dangers of lead poisoning and injunctive relief that
includes an order requiring defendants to pay for the detection and abatement
of lead paint in all public and private buildings within the State that are
accessible to children.
  On January 26, 2000, ARCO (as successor to IS&R) was named as a defendant in
a lawsuit, City of St. Louis v. Lead Industries Association, et al. (Cause No.
002-245), filed in the Circuit Court for the City of St. Louis, Missouri by the
City of St. Louis. The complaint, which also names the LIA and seven former
lead pigment/paint manufacturers, alleges causes of action for public nuisance,
product liability, negligence, negligent and fraudulent misrepresentations,
civil conspiracy, unjust enrichment, and indemnity. The City of St. Louis
alleges that it was obligated to pay, has paid, and in the future will have to
pay for the care of lead poisoned children and adults in the form of medical
care, education programs, abatement, and other costs associated with the
hazards created by the defendants, and is seeking unspecified compensatory and
punitive damages.
  On March 23, 2000, ARCO (as successor to IS&R) was named as a defendant in a
purported class action suit filed in California Superior Court by the County of
Santa Clara, County of Santa Clara v. ARCO, et al. (Case No. CV788657). Amended
complaints added the Counties of Alameda, Solano, Santa Cruz, Kern, the City
and County of San Francisco, the City of Oakland, the San Francisco Housing
Authority, the San Francisco Unified School District, the Oakland Housing
Authority, the Oakland Redevelopment Agency and the Oakland Unified School
District as plaintiffs and seek certification of a class of all public entities
in California who expend or have expended any funds for medical treatment,
educational expenses, abatement, property damage or other costs and expenses
due to exposure to or potential exposure to lead, with the exception of the
State of California and its agencies, offices, commissions, programs, bureaus,
authorities, departments, committees and boards. The second amended complaint,
which also names seven former lead pigment manufacturers or their alleged
successors and the LIA, alleges causes of action for fraud and concealment,
strict product liability, negligence, negligent breach of special duty,
nuisance, and violation of the California Business and Professions Code and
asserts a market share theory of liability and conspiracy allegations.
Plaintiffs seek unspecified compensatory, general, special, incidental and
punitive damages, disgorgement of profits from defendants' wrongful conduct,
abatement, civil penalties, an order enjoining defendants' wrongful conduct,
interest, costs and attorney's fees.
  On June 20 and 30, 2000, ARCO (as successor to IS&R) was named as a defendant
in lawsuits filed in the District Court of Harris County, Texas by the Spring
Branch Independent School District, Spring Branch ISD v. Lead Industries
Association, et al. (Case No. 2000-31175), and by the Houston Independent
School District, Houston ISD v. Lead Industries Association, et al. (Case No.
2000-33725). The petitions, which also name seven former lead pigment or lead
paint manufacturers or their alleged successors and the LIA, allege causes of
action for strict liability, negligence, fraud and negligent misrepresentation,
concert of action, conspiracy and indemnity. The petitions assert that
defendants are liable for costs that have been incurred and will be incurred as
lead paint is abated or remedied

                                       14


from the school districts' buildings and facilities. The petitions seek
unspecified compensatory and punitive damages, costs, interest and attorney's
fees.
  On July 1, 2000, ARCO (as successor to IS&R) was named as a defendant in a
purported class action suit filed in the Circuit Court of Cook County,
Illinois by Mary Lewis and Tashswan Banks, Lewis v. Lead Industries
Association, et al. (Case No. 00CH09800). The amended complaint, which also
names five former lead pigment/lead paint manufacturers and the LIA, alleges
causes of action for intentional failure to warn, supplier liability, fraud on
the public and civil conspiracy. Plaintiffs seek certification of a class of
parents or legal guardians of all minors residing in Illinois who have
undergone since January 1, 1992, or will undergo in the future, medical
screening or assessment for lead poisoning, and who have undergone, or will
undergo, continued medical monitoring to detect the onset of latent disease
associated with lead poisoning. The amended complaint seeks an order requiring
defendants to reimburse plaintiffs and class members for unspecified costs of
medical screenings, assessments and monitoring, a court-supervised medical
evaluation and monitoring program funded by defendants, costs and attorney's
fees.
  In addition, ARCO (as successor to IS&R) is a defendant in several lawsuits
brought on behalf of individual children allegedly injured from exposure to
lead paint, Brenner v. American Cyanamid Co., et al. (Supreme Court, Erie
County, New York), Thomas v. Lead Industries Association, et al. (Superior
Court, Milwaukee County, Wisconsin) and Smith, et al. v. Lead Industries
Association, et al. (Circuit Court of Baltimore City, Maryland). Summary
judgment was entered for defendants in Brenner, and the case now is on appeal.
Such cases, in the aggregate, are not material to the financial condition of
the company.
  On June 7, 1994, a purported class action was filed by several individuals
in United States District Court in Pittsburgh, Pennsylvania against ARCO and
Babcock & Wilcox Company (B & W) on behalf of persons "estimated to be in the
thousands" who lived or worked in Apollo and Parks Township, Pennsylvania, and
areas downwind of those places, from 1957 to the present. The suit, Hall, et
al. v. Babcock & Wilcox Company, et al. (Case No. 94-0951), claims that the
plaintiffs and alleged class members were exposed to releases of radioactive
and other toxic substances from two nuclear materials processing facilities
that have contaminated the air, soil, and surface and ground water in those
communities. The suit seeks damages for death and personal injury, diminution
in property values, costs of decontamination of property, injunctive relief
requiring defendants to establish a fund for medical monitoring, and punitive
damages. ARCO has been sued as the former owner of Nuclear Materials and
Equipment Corporation (NUMEC), the original owner and operator of the Apollo
and Parks Township facilities from March 1967 to November 1971. On
September 17, 1998, the jury in a trial of eight "test-case" plaintiffs'
claims returned a verdict of $33.7 million jointly and severally against ARCO
and B & W and another $2.8 million just against B & W. On September 24, 1998,
these eight test-case plaintiffs withdrew their claim for punitive damages
against ARCO. On June 29, 1999, the court granted ARCO's and B & W's motions
for a new trial. On November 15, 1999, as part of amending its responsive
pleading in the Hall action, B & W filed a crossclaim against ARCO for
contractual indemnity, common law indemnity, and contribution, seeking to be
indemnified by ARCO for any liability arising out of the Hall action. ARCO has
moved to strike the crossclaim, but the court has not yet ruled on ARCO's
motion. The claims of the eight test-case plaintiffs and of other plaintiffs
remain for trial or other disposition.
  On February 22, 2000, B & W filed a voluntary petition for relief under
Chapter 11 of the Bankruptcy Code in the United States Bankruptcy Court for
the Eastern District of Louisiana. On April 4, 2000, B & W filed an adversary
complaint in the Bankruptcy Court against the plaintiffs in the Hall v. B & W
action, seeing to confirm that the automatic stay applicable to actions
against the debtor operates to stay the Hall case in its entirety, including
any claims against ARCO. On October 6, 2000, the Bankruptcy Court denied to
confirm that the automatic stay applicable to stay the claims against ARCO in
the Hall case. B & W and ARCO are appealing this ruling to the District Court.
"On February 22, 2001, B&W filed a plan of reorganization that provides for
treatment of the Hall plaintiffs' claims against all defendants, including
ARCO, by means of a channeling trust. That plan has not been approved by the
bankruptcy court."

                                      15


  On April 13, 1995, a lawsuit was filed in United States District Court for
the Central District of California titled ARCO, et al. v. UNOCAL (Case No. 95-
2379-KMW-JRx). ARCO and five other refiners sought a declaration that UNOCAL's
U.S. Patent No. 5,288,393 (the '393 patent) is invalid and unenforceable. The
'393 patent purports to cover a substantial portion of the reformulated
gasoline compositions that were required by the State of California when the
Phase II regulations of the California Air Resources Board (CARB) went into
effect in March 1996. In the same lawsuit, UNOCAL filed a claim for
infringement of the '393 patent against ARCO and the five other refiners. On
July 15, 1997, the first phase of trial commenced and on October 14, 1997, the
jury found in UNOCAL's favor on the issues of whether ARCO and the other
refiners had infringed the '393 patent and whether that patent is valid. The
jury also found that ARCO had produced approximately 149 million gallons of
infringing gasoline during the first five months of production. On November 3,
1997, the jury found that each refiner owed UNOCAL $.0575 for each gallon of
gasoline that infringed on UNOCAL's patent. On September 29, 1998, the court
issued a judgment in favor of UNOCAL for $10.3 million (including prejudgment
interest) against ARCO for infringing gallons during the first five months of
production and for $1.5 million joint and several against ARCO and the other
five refiners for UNOCAL's attorneys fees. On March 29, 2000, the Court of
Appeals for the Federal Circuit affirmed the judgment. A petition for
certiorari to the United States Supreme Court was denied on February 20, 2001.
The case has been returned to the District Court for an accounting of the
amount of infringement which has occurred since the 5 month period for which
evidence was heard in the trial. Additionally, the defendants have advised the
court (and the plaintiff as required by local rule) that they intend to
request a new trial on the damage royalty rate subsequent to the 5 month
period.
  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 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. The court has certified a class of California residents who
bought CARB gasoline after March 1, 1996 other than for resale. On October 17,
1997, the court granted the defendants' motion for summary judgment. On
January 23, 1998, the court granted the plaintiffs' motion for a new trial. On
January 31, 2000, the Court of Appeal for the Fourth Appellate District
reversed the order granting a new trial and ordered the Superior Court to
grant summary judgment in favor of each defendant. On May 17, 2000, the
California Supreme Court granted a petition for review of this decision. On
January 23, 1998, the case of Gilley v. Atlantic Richfield, et al., [Case No.
CV UU132BTM (RBB)] was filed in the United States District Court for the
Southern District of California. The case, which is brought on behalf of a
purported class of wholesale purchasers of CARB gasoline including lessee and
contract gasoline dealers, claims violations of federal antitrust laws based
upon factual allegations that are essentially the same as those contained in
the Aguilar complaint. On October 22, 1998, ARCO was served with a complaint
filed in the Superior Court of California for the County of Sacramento
entitled Cal-Tex Citrus Juice, et al. v. Atlantic Richfield Company, et al.
(Case No. 98AS05227). The complaint is purportedly on behalf of a class of all
direct or indirect purchasers of California diesel fuel between March 19, 1996
and December 31, 1997 against all California refiners of California diesel
fuel. The complaint alleges violations of various state statutes by the
defendants' alleged conspiracy to fix prices of California diesel fuel and
seeks treble damages and restitution. The Gilley and Cal-Tex matters have been
stayed by their respective courts pending the outcome of the Supreme Court's
review of Aguilar.
  On June 26, 1998, a purported class action was filed in the Court of
Chancery of the State of Delaware in New Castle County, McMullin v. Beran, et
al. (Case No. 16493NC) against ARCO, Lyondell Petrochemical Company, ARCO
Chemical Company, and the individual directors of ARCO Chemical relating to
the acquisition of ARCO Chemical by Lyondell. The suit is brought by an
individual shareholder of ARCO Chemical on behalf of all common stockholders,
other than defendants, and seeks rescission of the transaction, damages for
the allegedly inadequate

                                      16


consideration being paid by Lyondell for the shares, and attorneys' fees and
costs. The plaintiff alleges that ARCO and the individual directors of ARCO
Chemical, who are alleged to be dominated and controlled by ARCO, breached
fiduciary duties to the minority shareholders. On December 1, 1999, the Court
of Chancery issued an order dismissing the action on the grounds that the
complaint did not state a valid claim under Delaware law. The plaintiff has
appealed the order of dismissal and that court heard arguments on the appeal
on July 25, 2000. On November 20, 2000, the Delaware Supreme Court reversed
and remanded to the Chancery Court for further proceedings.
  ARCO is defendant in an action pending in District Court in and for Potter
County, Texas styled TUCO, Inc. v. Thunder Basin Coal Company and Atlantic
Richfield Company (Case No. 79,483-C). Plaintiff, the corporate purchasing
agent for a public utility, alleges that defendants consistently charged in
excess of the proper contract price for coal used in the utility's power
plants, and fraudulently induced plaintiff to enter into the contract to
purchase the coal.

                           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."
  In addition to the matters reported herein, from time to time, certain of
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 release,
discharge, disposal, emission, storage and handling 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).
  In February 2001 ARCO entered into a consent decree in the lawsuit U.S. v.
ARCO Pipeline Company (Case No. 99-2161-GTV), filed in the U.S. District
Court, District of Kansas. Pursuant to the consent decree, settling a
petroleum products spill from a pipeline in Oswatomie, Kansas that impacted a
drinking water source, ARCO agreed to pay a civil penalty of $804,700.
  In response to a U.S. EPA program to enforce against alleged widespread air
pollution violations at petroleum refineries, BP negotiated with the U.S. EPA
and with several states a consent decree in respect of potential violations at
all of the eight U.S. refineries operated by BP subsidiaries, including those
operated by ARCO. ARCO and other BP subsidiaries entered into a consent decree
resolving the matter, which was lodged January 18, 2001 with the federal
district court for the Northern District of Indiana, Hammond Division, in the
case of United States, et al v. BP Exploration & Oil, Inc., et al (Civil
Action No. 2:96 CV 095 RL). That decree, if entered by the court, would
require payment of penalties totalling $10 million, and installation of
controls and procedural improvements in all of the refineries, including those
operated by ARCO.

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

                                 Introduction

  On April 18, 2000 ARCO was acquired by BP and became a part of the BP Group,
a worldwide integrated oil and gas and chemical business. BP, indirectly, now
owns all the common stock of ARCO. As part of the BP Group, the ARCO
businesses have been structured into business units, some of which were
combined with other businesses from the BP Group. The operations within the BP
Group are managed through four main businesses, Exploration and Production,
Gas and Power, Refining and Marketing and Chemicals. Gas and Power and
Chemicals businesses are not material to ARCO. The financial position and
results of operations of heritage ARCO entities should be understood in the
context of this relationship. See Note 1 of Notes to Consolidated Financial
Statements for a further discussion of the acquisition. The financial
statements of ARCO reflect the historical costs to the previous shareholder
group and, accordingly, do not reflect any purchase accounting adjustments
related to the acquisition of ARCO by BP.
  The Operating Review that follows explains the major changes in ARCO's key
businesses as related to prices, production volumes, sales, and expenses for
the years 2000 and 1999. The consolidated results of these operations are
examined in relation to the Consolidated Statement of Income on page 38.

Operating results     $ 1,831 $ 1,128 $    386
                      =========================



The increase in ARCO's 2000 operating results from worldwide oil and gas
exploration and production operations primarily resulted from higher crude oil
and natural gas prices and lower exploration expenses, partially offset by the
absence of income from Alaskan oil producing properties following their sale
in the second quarter of 2000. Exploration expense associated with
international operations declined $97 million before tax primarily as a result
of lower writeoffs for dry holes.
  The 2000 special items included charges of $512 million after tax primarily
for the impairment of oil and gas properties in Latin America and additional
severance and vacant space reserves, partially offset by a gain of
$131 million after tax on the sale of Vastar's interest in a joint venture and
a net gain on other asset sales.

In 1999, ARCO's operating results from worldwide oil and gas exploration and
production operations were significantly impacted by higher crude oil prices
and, to a lesser extent, higher natural gas volumes and domestic natural gas
prices.

                         Results of Segment Operations

In addition, as a result of the company's cost reduction program, combined
operating, exploration, and selling, general and administrative (SG&A)
expenses before tax were more than $500 million lower, compared to 1998.
  In 1999, special items included a net charge of $190 million after tax,
primarily for the loss on the disposition of a portion of ARCO's interest in
the Rhourde El Baguel field in Algeria and for the anticipated loss on the
sale of office space in Plano, Texas. Charges for impairment in 1999 were
insignificant.
  In 1998, special items included after-tax charges of $925 million for the
impairment of oil and gas properties, including $507 million related to former
UTP properties. Special items also included after-tax charges of $107 million
primarily for employee termination costs associated with restructuring. These
charges were partially offset by tax-related benefits of approximately
$30 million.

                  =============================



The significant decline in 2000 U.S. petroleum liquids production resulted
from the sale of Alaskan producing properties in the second quarter of 2000.
The increase in Vastar's petroleum liquids production in 2000 resulted from
the startup of production from the Mississippi Canyon 764 block in the Gulf of
Mexico deepwater in the second quarter of 2000. The decline in other Lower 48
petroleum liquids production primarily reflected the sale of ARCO Long Beach,
Inc. in the second quarter of 2000. ARCO Long Beach, Inc. produced
approximately 30,200 barrels per day (BPD) in 1999.
  The decline in international petroleum liquids production primarily
reflected lower United Kingdom and Indonesian volumes. The decrease in United
Kingdom volumes of nearly 20,000 BPD primarily resulted from the sale of oil
fields in the second quarter of 2000. The decrease in Indonesian volumes of
approximately 9,000 BPD resulted from the impact of higher crude oil prices on
production sharing contracts.
  The 1999 decrease in U.S. petroleum liquids production primarily resulted
from natural field declines in Alaska and the absence of production from
California heavy crude oil properties (other Lower 48) that produced
approximately 32,000 BPD in 1998. The California properties were exchanged in
October 1998 for Gulf of Mexico exploration acreage and properties producing
both crude oil and natural gas that were ultimately transferred to Vastar. The
lower Alaska petroleum liquids production primarily reflected natural field
decline at the Prudhoe Bay, Kuparuk River and Greater Point McIntyre fields
partially offset by increases in satellite field production.
  The 1999 increase in international petroleum liquids production primarily
reflected the impact of a full year of production contributed by former UTP
properties in 1999 versus only six months of production in 1998.

                         Results of Segment Operations

  All geographic areas experienced lower natural gas production in 2000,
primarily due to property sales and natural field declines.
  In 1999, the growth in international natural gas production reflected
increased production from the United Kingdom North Sea, primarily a full year
of production from UTP properties acquired in June 1998. The growth was
partially offset by a decrease in Indonesian natural gas production as a
result of the impact of higher natural gas prices on production sharing
contracts. The increase in U.S. natural gas production primarily resulted from
Vastar's 9% growth in production. Vastar's increased production reflected the
production from the Gulf of Mexico properties transferred to Vastar late in
1998, and production increases achieved from new field startups and
operational improvements at West Cameron 645, Mississippi Canyon 148, the San
Juan Basin and other fields.

Operating results     $   428 $   596 $   281
                      =======================


The decline in 2000 earnings primarily resulted from lower margins. Higher
product prices were more than offset by higher crude oil costs, higher
purchased finished product prices and volumes, and higher utility and fuel
costs. Margins on the sale of purchased products are lower than on products
produced. As in prior years, an increase in gasoline sales volume in 2000
required the company to buy refined product on the spot market, as the
company's two refineries were operating near capacity during the year.
  Improved operating results in 1999, compared to 1998, primarily resulted
from higher light product margins. The effect of West Coast refinery outages
in the second quarter of 1999 impacted supply in the second and third quarters
resulting in higher product realizations. The higher product sales prices were
partially offset by higher crude oil costs.
  The amortization and recognition of imputed interest associated with the
deferral of part of the pretax gain on the sale of the ARCO Chemical interest
in 1998 had a net favorable impact of approximately $42 million, $44 million
and $17 million after tax on refining and marketing earnings in 2000, 1999 and
1998, respectively. See "Gain on Disposition of Discontinued Operations" on
page 26.
  Special items in 2000 primarily included charges for future environmental
remediation, additional severance and legal reserves.
  In 1998, a special items charge of $13 million for personnel reductions as-
sociated with ARCO's cost reduction programs was offset by favorable legal
settlements.

Results from ARCO's other operations comprise earnings from Lower 48 pipeline
operations and an aluminum rolling facility. The decline in operating results
in 2000 primarily resulted from the absence of income from certain pipeline
assets sold to comply with the FTC-mandated sale of assets required for
approval of the acquisition of ARCO by BP, as well as lower margins for
aluminum operations.
  Excluding the special items, the decline in operating results in 1999
reflected decreased earnings from the pipeline operations, primarily as a
result of the transfer of certain pipeline operations to the refining and
marketing segment. This decline was partially offset by a $3 million increase
in equity earnings from the 50% owned Seaway pipeline joint venture in the
Midcontinent.
  Operating results from the aluminum operations were relatively flat for the
two years ended December 31, 1999.
  The 2000 and 1999 special items primarily consisted of charges for severance
reserves in 2000 and gains from asset sales in 1999. The 1998 special items
included gains from pipeline asset sales, partially offset by pipeline
restructuring charges.

Unallocated expenses in 2000 included after-tax charges incurred in connection
with the BP acquisition of ARCO, future environmental remediation and
restructuring costs of $97 million, $237 million and $134 million,
respectively. The increase in these amounts, compared to 1999, was partially
offset by interest earned on the receivable from BP and further reductions in
corporate staff and general expenses.
  After-tax charges for future environmental remediation and restructuring
costs were $24 million and $8 million in 1999, compared to $143 million and
$48 million, respectively, in 1998. These decreases, along with a reduction in
corporate staff and general expenses of approximately $90 million after tax,
was only partially offset by lower tax benefits and decreased interest income
on short-term investments, resulting in unallocated net income in 1999.
  In 1998, unallocated net expense primarily included charges of $143 million
after tax for future environmental remediation, charges of $48 million after
tax for restructurings, corporate staff and general expenses, and interest
revenue.
  The environmental charges in 1998 related both to current operations and
natural resource damage liabilities in the state of Montana associated with
previously discontinued mining operations.
  The increase in interest expense in 2000 primarily reflected lower
capitalized interest and interest paid to BP for funds advanced to certain
subsidiaries of ARCO following the acquisition of ARCO by BP. Gross after-tax
interest expense declined in 1999 after taking into account the effect on 1998
interest expense of a $94 million after-tax interest credit associated with a
tax refund received in 1998. The decrease in 1999 was due primarily to higher
capitalized interest. The impact of increased interest capitalization more
than offset the increase in combined short- and long-term debt outstanding
during 1999.

                         Results of Segment Operations


Extraordinary Loss on Extinguishment of Debt
The company incurred a loss of $243 million before tax, or $152 million after
tax, on early retirement of long-term debt during 2000. The early retirements
will result in a pre-tax reduction in interest expense on long-term debt of
approximately $75 million in 2001.

Gain on Disposition of Discontinued Operations

ARCO Chemical
In July 1998, ARCO sold its entire interest in ARCO Chemical to Lyondell
Chemical Company (Lyondell) for cash proceeds of $4.6 billion. After deferral
of $313 million of the pre-tax gain as discussed below, ARCO recorded a net
after-tax gain of $1.053 billion. In 1999, adjustments for tax benefits
resulted in the recording of an additional after-tax gain on disposition of
$59 million.
  In 1992 the company entered into a 10-year purchase agreement with ARCO
Chemical providing for the delivery of fixed quantities of methyl tertiary
butyl ether (MTBE) at a formula-based price. At the inception of the contract,
a liquid spot market for MTBE did not exist. As the spot market has developed,
the formula-based prices have historically been above spot market prices.
Provision for loss on the contract was not necessary prior to the sale to
Lyondell because ARCO Chemical was a consolidated, majority-owned subsidiary
of the company. ARCO believes that, at the date of sale of ARCO Chemical to
Lyondell, the pricing terms were above-market as compared to similar toll-
based contracts.
  The above-market MTBE contract value was reflected in the sale price of the
company's interest in ARCO Chemical. As a result, ARCO deferred $313 million
of the pre-tax gain on sale of the ARCO Chemical interest. This deferral
represents the estimated discounted present value of the difference over the
remaining term of the contract (which terminates in 2002) between the contract
price and the spot market price for MTBE. ARCO does not expect that the above-
market differential will decrease over the remaining term.
  The deferral is being amortized over the remaining term of the contract on
the basis of annual volume over total contracted volume. The amortization and
recognition of imputed interest had a net favorable impact of approximately
$42 million, $44 million and $17 million after tax on earnings of the refining
and marketing segment in 2000, 1999 and 1998, respectively.

Coal
In the second quarter of 2000, ARCO disposed of its remaining coal assets in
Australia. Upon the sale of those assets, a provision originally established
in 1998 for the estimated loss on sale of U.S. and Australian coal assets was
reduced, resulting in an after-tax gain of $89 million.
  In 1998, ARCO recorded a $92 million provision for the estimated loss on the
disposal of the U.S. and Australian coal assets. In 1999, upon the sale of
ARCO's 80% interest in the Gordonstone coal mine and its 31.4% interest in the
Blair Athol Joint Venture the provision was reduced resulting in an after-tax
gain of $22 million.
  In June 1998, for cash consideration of approximately $1.1 billion, ARCO
disposed of its U.S. coal operations in a transaction with Arch Coal (Arch).
Operations disposed of included the Black Thunder and Coal Creek mines in
Wyoming, the West Elk mine in Colorado, and ARCO's 65% interest in three mines
in Utah. The Colorado and Utah mines were sold outright. ARCO contributed its
Wyoming coal operations and Arch transferred various of its coal operations
into a new joint venture that is 99% owned by Arch and 1% owned by ARCO.

                         Results of Segment Operations


UTP Petrochemical
At the time of the UTP acquisition, ARCO determined the UTP petrochemical
operations would be divested. In March 1999, ARCO sold the UTP petrochemical
business and recorded a small loss.

                      Results of Consolidated Operations

Income from Continuing Operations

In 2000, the increased operating results were the result of higher crude oil
and natural gas prices and lower exploration expenses, partially offset by
lower refined products margins.
  The improvement in ARCO's income from continuing operations in 1999
primarily reflected higher crude oil prices, increased refined products
margins, lower operating, exploration and SG&A expenses and higher natural gas
volumes.

Revenues

The increase in exploration and production sales revenues resulted primarily
from higher crude oil and natural gas prices being offset to a large extent by
significantly lower petroleum liquids production, which resulted from the sale
of the company's Alaskan oil and gas operations, and the cessation of the
domestic crude oil marketing activity following ARCO's acquisition by BP.
Refining and marketing sales revenues increased primarily because of higher
light product prices, which reflected the increased crude oil prices and, to a
lesser extent, higher gasoline sales volumes compared to the prior year.
  In 1999, the increase in exploration and production sales revenues resulted
from higher petroleum liquids prices and natural gas production volumes,
partially offset by lower petroleum liquids volumes.

                      Results of Consolidated Operations


Other Revenues

Other revenues increased in 2000 reflecting a $202 million pre-tax gain from
sale of Vastar's interest in SCEM and a $77 million pre-tax gain from the sale
of stock to the public by an insurance company in which ARCO was a mutual
participant.
  In 1999, higher other revenues, compared to 1998, reflected one-time legal
settlements and increased interest and rental income.
  Related party interest in 2000 relates to an intercompany receivable from BP
that has been outstanding since the sale of Alaskan operations in the second
quarter 2000.

Expenses

The increased trade purchases and trade purchases from related parties in 2000
reflected the purchases of Alaskan crude oil by the refining and marketing
operations following the sale of ARCO's Alaskan oil and gas operations to
Phillips Petroleum. Prior to the sale of the Alaskan operations those
purchases were eliminated as intercompany transactions in the consolidated
financial statements. In addition, trade purchases reflected the effect of
increased crude oil prices and higher gasoline purchases by the company's
refining and marketing operations.
  In 1999 trade purchases were higher primarily as a result of increased
purchases of finished and unfinished refined product from third parties and
higher crude oil prices associated with crude oil marketing activity.
  Operating expenses were higher in 2000 primarily as a result of $521 million
in before-tax charges for future environmental remediation, compared to $57
million in 1999.
  In 1999 operating expenses declined as a result of a decrease in exploration
and production operating costs of approximately $190 million before tax,
compared to 1998. This decline was due to the 1998 exchange of higher cost
California heavy crude oil properties for Gulf of Mexico crude oil and natural
gas properties, as well as the impact of the company's cost reduction program.
In addition, charges for future remediation and reclamation were $57 million
in 1999, compared to $234 million in 1998. The 1998 charges related to both
current operations and to natural resource damage liabilities in the state of
Montana associated with previously discontinued mining operations.
  SG&A expenses in 2000 primarily reflected lower expenses associated with
international exploration and production operations and lower corporate
administrative expenses.
  In 1999, SG&A expense declined primarily as a result of lower personnel
costs and a favorable adjustment to self-insurance reserves for estimated
claims incurred but not yet reported.
  DD&A expense in 2000 declined primarily as a result of the sale of the
Alaskan oil and gas producing operations in April 2000 and also the sale of
oil and gas properties associated with the Company's international exploration
and production operations.
  In 1999 DD&A expense, compared to 1998, was higher as a result of a full
year of DD&A associated with the former UTP operations, which became a part of
ARCO's operations in the third quarter of 1998. In addition, DD&A expense also
increased as a result of increased natural gas production and higher average
depletive writeoff rates associated with Vastar's operations.
  In each of the last 3 years ARCO has performed an impairment review of
certain oil and gas properties. The review in 2000 resulted in an impairment
charge of $286 million before tax primarily related to several Latin American
oil fields along with smaller impairments of properties in the United States
and Europe. The 1999 impairment review resulted in insignificant charges
related to a few isolated properties.
  The review in 1998 resulted in an impairment charge of $1,447 million. The
impaired properties included former UTP properties in Pakistan, Latin America
and the U.K. North Sea, as well as other ARCO properties in California, the
U.K. North Sea, North Africa and the Middle East.

                      Results of Consolidated Operations

  The decline in 2000 exploration expense reflected lower writeoffs for dry
holes and lower other exploration expenses associated with ARCO's
international oil and gas operations, partially offset by the writeoff of two
domestic deepwater offshore wells in the first quarter of 2000.
  In 1999 lower exploration expense reflected a decline in geological and
geophysical and dry-hole expense in ARCO's international oil and gas
operations and a decline in Vastar's dry-hole expense.
  Taxes other than income taxes in 2000 did not reflect the increase in crude
oil prices, as the crude oil price increase was offset by lower production
volumes resulting primarily from the sale of the company's Alaskan oil and gas
producing operations.
  In 1999, taxes other than income taxes declined as lower production volumes
on which certain production taxes are based more than offset the increase in
crude oil prices.
  The higher interest expense (other than that paid to related parties) in
2000 primarily resulted from lower capitalized interest as a result of the
sale of ARCO's interest in an oil field in Algeria in the second quarter of
2000 and the completion of projects in the U.K. and Latin America that were
ongoing in 1999.
  Related party interest expense is associated with the net amount of funds
advanced by BP primarily for ARCO's United Kingdom oil and gas producing
operations.
  In 1999 interest expense was slightly lower, compared to 1998, after taking
into account the effect on 1998 interest expense of an interest credit
associated with a tax refund received in 1998. The decline resulted from the
impact of increased interest capitalization more than offsetting the increase
in combined short and long-term debt outstanding during 1999.
  The restructuring costs in 2000 represented charges for the costs associated
with the acquisition of ARCO by BP, primarily employee terminations. The $20
million of restructuring charges in 1999 relates to an adjustment of a 1998
accrual for employee terminations, primarily due to the elimination of
additional positions. In 1998, $229 million of the restructuring charges
related to costs of eliminating approximately 1,200 positions specifically
identified as of December 31, 1998. See Note 11 of Notes to Consolidated
Financial Statements on page 51 regarding restructuring costs.

Income Taxes

The company had an effective tax rate of 34.0% and 27.8% in 2000 and 1999,
respectively. An effective tax rate lower than the statutory rate in both 2000
and 1999 primarily reflected various tax credits and other benefits, partially
offset by taxes on foreign income in excess of statutory rate.

affecting the industry, as well as changes in environmental rules and
regulations and the tax laws.
  Following the acquisition of ARCO by BP on April 18, 2000, ARCO became part
of the BP Group, a worldwide integrated oil and gas and chemical business. As
part of the BP Group, ARCO participates in BP's cash management system, where
the bank sends daily notification of checks presented for payment. BP
transfers funds from other sources to cover the checks presented for payment.
This program generally results in book overdrafts as a result of checks
outstanding. At December 31, 2000, these book overdrafts have been
reclassified to accounts payable.
  As a participant in BP's cash management system, ARCO must look to BP for
the funding of its future cash requirements for working capital, capital
expenditures and debt repayments.
  Cash and cash equivalents and short-term investments totaled $294 million at
year-end 2000. ARCO had no short-term borrowings at December 31, 2000 and
long-term debt due within one year was $304 million.
  The company was in a working capital deficit position of $893 million at
December 31, 2000.

               Market-Sensitive Instruments and Risk Management


  The following discussion of the company's risk-management activities
includes "forward-looking statements" that involve risk and uncertainties.
Actual results could differ materially from those projected in the forward-
looking statements.
  Prior to its acquisition by BP, ARCO managed the effects of foreign currency
and interest rate fluctuations through the use of foreign currency forward,
option and swap contracts, interest rate swaps and financial futures
contracts.
  Following the acquisition, ARCO stopped engaging in hedging activity and by
December 31, 2000, all hedging contracts in place prior to the acquisition had
expired, except for some immaterial commodity hedging principally associated
with the aluminum operations.
  At December 31, 2000, the company held a variety of financial instruments
and a small number of derivative instruments that are sensitive to changes in
interest rates and commodity prices.
  In the normal course of business, the company also faces risks that are
either nonfinancial or nonquantifiable. Such risks principally include country
risk, credit risk and legal risk and are not discussed or quantified in the
following analyses.

Interest Rate Risk

The fair value of the company's cash and short-term investment portfolio
December 31, 2000, approximated carrying value. Given the short-term nature of
these instruments, market risk, as measured by the change in fair value
resulting from a hypothetical 1% change in interest rates, is not material.
  The fair value of the company's long-term debt, including current maturi-
ties, was estimated to be $4.7 billion at December 31, 2000, and exceeded the
carrying value by $260 million. Market risk was estimated at $260 million,
representing potential increase in fair value resulting from a hypothetical 1%
decrease in the company's weighted average long-term borrowing rate at Decem-
ber 31, 2000. Interest rate risk is mitigated by the use of floating rate in-
struments, which comprise approximately $200 million of the company's long-
term debt.

Foreign Exchange Rate Risk

At December 31, 2000, ARCO had no significant financial instruments
denominated in a foreign currency or foreign currency derivatives outstanding.

Commodity Price Risk

Prior to the acquisition of ARCO by BP, the company used various hedging ar-
rangements, predominantly natural gas swaps and crude oil futures and options,
to manage the company's exposure to price risk from its natural gas and petro-
leum liquids production. These hedging arrangements had the effect of locking
in for specified periods (at predetermined prices or ranges of prices) the
prices the company will receive for the volumes to which the hedge relates. As
a result, while these hedging arrangements are structured to reduce the
company's exposure to decreases in price associated with the hedging commodi-
ty, they also limit the benefit the company might otherwise have received from
any price increases associated with the hedged commodity.
  Following the acquisition, ARCO stopped engaging in the hedging of its
natural gas and petroleum liquids production.

Equity Price Risk

Other investments at December 31, 2000, included marketable equity securities
which are recorded at fair value of $712 million, including net unrealized
gains of $219 million. Those securities have exposure to price risk. The
estimated potential loss in fair value resulting from a hypothetical 10%
decrease in prices quoted by stock exchanges is $71 million.

               Market-Sensitive Instruments and Risk Management


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.

During 2000, management of the Company assessed the estimated future costs to
remediate all of the Company's environmental sites and concluded that its best
estimate of the cost to remediate such sites was greater than previously
recorded. As a result the environmental reserve was increased by $521 million
during 2000, of which $274 million was recognized during the fourth quarter.

* Total long-term and short-term liabilities

  The amount accrued represents the estimated undiscounted costs that ARCO
will incur to complete the remediation of sites with known contamination. In
view of the uncertainties associated with estimating these costs, such as
uncertainty regarding the appropriate method for remediation of various sites
and regarding ARCO's ultimate share of costs, it is possible that actual costs
could be significant. Although these costs might be material to the results of
operations in the period in which they are recognized, ARCO does not expect
that such costs will have a material effect on ARCO's financial position or
equity. See Note 19 of Notes to Consolidated Financial Statements regarding
environmental matters.
  The increased payments against the environmental reserves in 1999 reflected
a payment of $160 million in settlement of a majority of the State of
Montana's claims in a lawsuit resulting from mining and mineral processing
businesses formerly operated by Anaconda.
  In addition to the provision for environmental remediation costs, $312
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.

                 Statements of Financial Accounting Standards
                                Not Yet Adopted

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133
requires companies to adopt its provisions for all fiscal quarters of all
fiscal years beginning after June 15, 2000 (as deferred by SFAS No. 137).
Earlier application of all of the provisions of SFAS No. 133 is permitted, but
the provisions cannot be applied retroactively to financial statements of
prior periods. SFAS No. 133 standardizes the accounting for derivative
instruments by requiring that an entity recognize those items as assets or
liabilities in the statement of financial position and measure them at fair
value.

  Following the acquisition of ARCO by BP, ARCO no longer engages in
significant hedging activity using derivative instruments. Accordingly, the
impact of SFAS No. 133 will not be material to stand-alone ARCO financial
statements.

                                      33


                  Safe Harbor for Forward-Looking Statements

  ARCO desires to take advantage of the "safe harbor" provisions for forward-
looking statements contained in Section 27A of the Securities Act and Section
21B of the Exchange Act and is including this statement in order to do so.
Such statements are generally accompanied by words such as estimate, project,
predict or expect, that convey the uncertainty of future events or outcomes.
These statements may include projections and estimates concerning the timing
and success of specific projects, the size and timing of cost reductions, the
level of future income, production volumes, size of hydrocarbon resources,
ability to replace reserves and levels of capital spending. Actual results
could differ materially based on numerous factors, including those described
below. Unless otherwise noted in the statements, ARCO does not intend to
update any forward-looking statements.

Price Volatility, Political, Economic and Regulatory Instability

Volatility in prices and margins affects all of the company's businesses.
Volatility is caused by a number of factors, including changes in market
supply and demand balances and fluctuations in political, regulatory and
economic climates throughout the world.
  The ability to operate ARCO's businesses is dependent on the politics and
regulations in the U.S. and in the particular geographic regions where the
company operates. The 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.

Decline in Oil and Gas Prices

Any substantial or extended decline in oil and gas prices could have a
material adverse effect on ARCO's financial position and results of
operations, on the quantities of crude oil and natural gas reserves that
economically may be produced and on the quantity of proved reserves that may
be attributed to our properties.

Production Rates and Reserve Replacement

Projecting future rates of oil and gas production is inherently imprecise.
Production rates of oil and gas reservoirs generally decline. Future
production rates can be affected by price volatility and the company's ability
to replace depleting reserves. There can be no assurances: (a) as to the level
or timing of success, if any that the company will have in acquiring or
finding and developing economically recoverable reserves; (b) that estimates
of proved reserves will not be revised in the future; or (c) that the actual
quantities of oil and gas ultimately recovered will not differ from the
reserve estimates.

Refining & Marketing

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. Volumes
produced and margins historically have been volatile and are impacted by
market demand, regulatory changes (particularly environmental regulations
regarding gasoline), the price of crude oil, and the ability of regional
refiners and the company to provide a sufficient supply of refined products.

Operating Hazards

Operations are subject to various hazards common to the industry, including
explosions, fires, uncontrollable spills, and damage from severe weather
conditions.

                  Notes to Consolidated Financial Statements

Note 1 Acquisition of ARCO by BP

  On April 18, 2000, BP completed the acquisition of ARCO pursuant to the
terms of the merger agreement dated March 31, 1999, as amended through March
27, 2000 (Merger Agreement). The Merger Agreement, approved by the boards of
both BP and ARCO, provided for all common shareholders of ARCO, with the
exception of BP, ARCO or any of their subsidiaries, to receive 9.84 BP
ordinary shares, each in the form of BP American Depositary Shares (ADSs) or,
at the election of the shareholder, BP ordinary shares, in return for the
cancellation of each of their shares (other than the shares held by CH-Twenty
Holdings, LLC, a subsidiary of ARCO) (the Cancelled ARCO Shares). It also
provided for the issue to BP of new common shares equal in number to the
Cancelled ARCO Shares. Any right to a fraction of a BP ADS or an odd lot of
less than six BP ordinary shares was satisfied by a cash payment. In addition,
the outstanding ARCO common stock was delisted from the New York Stock
Exchange (NYSE) and other exchanges on which it had been listed.
  Following the acquisition, ARCO's outstanding shares of $2.80 and $3.00
Preference Stock remained listed on the NYSE. Pursuant to the Merger
Agreement, each share of $2.80 Preference Stock was converted into the right
to receive 7.872 ADSs and each share of $3.00 Preference Stock was converted
into the right to receive 22.304 ADSs.
  Following the acquisition of ARCO by BP, ARCO became part of the BP Group,
and the ARCO businesses have been structured into business units, some of
which were combined with other businesses of the BP Group. The operations
within the BP Group are managed through four main businesses, Exploration and
Production, Gas and Power, Refining and Marketing and Chemicals. Gas and Power
and Chemical operations are not material for ARCO.
  The financial position and results of operations of ARCO should be
understood in the context of this relationship. The financial statements of
ARCO reflect the historical costs to the previous shareholder group and,
accordingly, do not reflect any purchase accounting adjustments related to the
acquisition of ARCO by BP. Significant intercompany accounts and transactions
between BP and its affiliates and ARCO are disclosed as related party
transactions in Note 3.

Note 2 Accounting Policies

ARCO's accounting policies conform to accounting principles generally accepted
in the United States, including the "successful efforts" method of accounting
for oil and gas producing activities. Unless otherwise stated, the Notes to
Consolidated Financial Statements exclude discontinued operations.

Principles of Consolidation
The consolidated financial statements include the accounts of all subsidiar-
ies, ventures and partnerships in which a controlling interest is held. ARCO
also consolidates its interests in undivided interest pipeline companies and
in oil and gas joint ventures. ARCO uses the equity method of accounting for
companies where its effective ownership is between 20% and 50% and for other
ventures and partnerships in which a controlling interest is not held.

Revenue Recognition
Revenues are generally recognized upon the passage of title, net of royalties,
if applicable.

Cash Equivalents
Cash equivalents consist of highly liquid investments, such as time deposits,
certificates of deposit and marketable securities other than equity securi-
ties, maturing within three months of purchase. Cash equivalents are stated at
cost, which approximates fair value.

                                      42


                  Notes to Consolidated Financial Statements


Oil and Gas Unproved Property Costs
Unproved property costs are initially capitalized. Significant unproved prop-
erties are not amortized but are periodically assessed for impairment. Other
unproved properties are amortized on a composite basis, considering past suc-
cess 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. Ex-
ploratory wells that find oil and gas reserves which cannot be classified as
proved within one year of discovery and do not continue to qualify as capital-
ized costs are charged to expense as dry-hole costs.

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.

Impairment of Long-lived Assets
Long-lived assets are assessed for possible impairment in accordance with
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," whenever changes in economic or operating conditions indicate the
carrying amount may not be recoverable. If undiscounted future cash flows are
less than the carrying amount, an impairment loss is recognized to the extent
the carrying amount exceeds future discounted cash flows. For proved oil and
gas properties, the assessment is performed on an individual field basis and
is based on the company's price forecast used for economic decision making.

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 operations are accrued during production and
classified as a long-term liability. Such costs are taken into account 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 method pre-
scribed by Accounting Principles Board Opinion (APB) No. 25.

Earnings per Share
Earnings per share for 2000 has been omitted from ARCO's financial statements
because ARCO had no publicly held common stock after ARCO's acquisition by BP
on April 18, 2000.

                                      43


                  Notes to Consolidated Financial Statements

  Basic earnings per share was based on the average number of common shares
outstanding during each period. Diluted earnings per share included as out-
standing certain contingently issuable shares, primarily stock options and
convertible preference stock.

Use of Estimates
The preparation of financial statements in conformity with accounting princi-
ples generally accepted in the United States requires management to make esti-
mates and assumptions that affect the reported amounts of assets and liabili-
ties 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.

Derivative Instruments
Prior to the acquisition of ARCO by BP, the company used a variety of
derivative instruments, both financial and commodity based, to minimize the
market risks of commodity price, interest rate and foreign currency
fluctuations. The company did not hold or issue derivative instruments for
trading purposes and was not a party to leveraged instruments. All derivative
instruments were off-balance sheet instruments; however, net receivable or
payable positions related to derivative instruments were carried on the
balance sheet. The nature of the transaction underlying a risk management
strategy, primarily whether or not the instrument qualified as a hedge,
determined which accounting method was used.
  In order to qualify for hedge accounting, the derivative instrument must be
effective as a hedge and designated as such.
  Deferral accounting was used for the following types of transactions (if the
instrument qualified as a hedge): future crude oil and natural gas production;
fixed-price crude oil and natural gas purchase and sale commitments; U.S. dol-
lar-denominated debt issued by a foreign subsidiary; debt denominated in a
foreign currency; and anticipated foreign currency commitments. Under this
method, deferred gains and losses were included in other assets or accrued li-
abilities until the designated underlying item was recognized in income. Rec-
ognized gains and losses were recorded in sales and other operating revenues,
other revenues or trade purchases depending on the underlying item associated
with the derivative. Instruments typically used in these transactions were
crude oil and natural gas swap and price collar contracts and some foreign
currency swap, forward and option contracts.
  The accrual method of accounting was used for interest rate swap agreements
entered into by the company which convert the interest rate on fixed-rate debt
to a variable rate. Under the accrual method, each net payment or receipt due
or owed under the derivative was recognized in income in the period to which
the payment or receipt relates. Amounts to be paid/received under these
agreements were recognized as an adjustment to interest expense. The related
amounts payable to/receivable from the counterparties were included in other
accrued liabilities.
  The fair value method of accounting was used for any derivative instrument
that did not qualify as a hedge. The fair value method, whereby gains and
losses associated with changes in fair value of a derivative instrument were
recognized currently in income or in accumulated other comprehensive income,
was used for the following derivative instruments: foreign currency forward
and option contracts associated with anticipated future cash flows related to
overseas operations, and foreign currency swap contracts associated with
foreign-denominated intercompany debt with maturities exceeding one year.
Changes in fair value of all transactions accounted for under this method were
recognized currently in income and reported as other revenues.
  Under all methods of accounting, the cash flows related to any recognized
gains or losses associated with derivative instruments were reported as cash
flows from operations.

                                      44


                  Notes to Consolidated Financial Statements

  If a derivative instrument designated as a hedge was terminated prior to
expected maturity, gains or losses were deferred and included in income when
the underlying hedged item was recognized in income.
  When the designated item associated with a derivative instrument matured,
was sold, extinguished or terminated, gains or losses were recognized as part
of the gain or loss on sale or settlement of the underlying item. When a
derivative instrument was associated with an anticipated transaction that was
no longer expected to occur, the gain or loss on the derivative was recognized
immediately in income.

Reclassifications
Certain previously reported amounts have been restated to conform to
classifications adopted in 2000.

Note 3 Relationship with BP and Other Related Party Transactions

Following the acquisition of ARCO by BP on April 18, 2000, BP and certain of
its affiliates began providing certain senior management services, legal
services, tax services, risk management and various other corporate services
to ARCO. The incremental cost of these services is not material and is not
included in the financial statements of ARCO.
  ARCO participates in BP's cash management system, where the bank sends daily
notification of checks presented for payment. BP transfers funds from other
sources to cover the checks presented for payment. This program generally
results in book overdrafts as a result of checks outstanding. At December 31,
2000, these book overdrafts have been reclassified to accounts payable.
  Sales to and purchases from BP or its subsidiaries consisted primarily of
the sale or purchase of petroleum liquids and natural gas. The sales to other
related parties primarily included sales to Southern Company Energy Marketing
(SCEM), an equity affiliate of Vastar Resources, Inc. (Vastar) and consisted
of sales of natural gas produced by Vastar. Vastar sold its interest in SCEM
in September, 2000.
  Sales to related parties were as follows:

ARCO and its subsidiaries will join with BP America Inc. (BP America), a
subsidiary of BP, in filing a consolidated federal income tax return for
periods subsequent to the acquisition of ARCO by BP. ARCO and BP America are
parties to a tax sharing agreement which requires ARCO as a member of BP
America's consolidated tax group to pay its share of the group's federal
income taxes and certain state and local taxes to BP America. ARCO's share of
these taxes is generally the amount of federal income tax it would have to pay
if ARCO and its subsidiaries filed tax returns as a separate tax group.

                                      45


                  Notes to Consolidated Financial Statements

  ARCO entered into a long-term deposit agreement with BP America in which the
initial deposit consisted of the proceeds from the sale of the Alaskan oil and
gas businesses. Subject to the provisions of early termination the funds will
continue to be on deposit until January 1, 2002. In September 2000, ARCO
withdrew $1.5 billion to purchase Vastar's publicly held minority
stockholding. The interest rate is tied to the LIBOR rate or such other rate
as may be agreed between the parties.

Note 4 Sale of Alaskan Operations

In the second quarter of 2000 ARCO completed the sale of its Alaskan
operations, comprising oil and gas production, crude oil marine transportation
and related crude oil inventory, for proceeds totaling approximately
$6.2 billion and realized an after-tax gain of approximately $1.8 billion. The
net book value of those assets at the time of the sale was approximately $3.2
billion. The gain on the inventory portion of the sale included a $69 million
after-tax gain from LIFO inventory liquidation. The results of the Alaskan oil
and gas producing and marine transportation operations through the dates of
sale are included in ARCO's twelve-month results ended December 31, 2000.
  In the third quarter of 2000 ARCO sold its Alaskan pipeline operations,
thereby completing the sale of all Alaskan operations mandated by the Federal
Trade Commission in obtaining approval for the acquisition of ARCO by BP. ARCO
received proceeds of $308 million and recorded an after-tax loss of $34
million. The results of the Alaskan pipeline operations through the date of
sale are included in ARCO's twelve-month results ended December 31, 2000.
  The following table sets forth the operating results for the Alaskan oil and
gas producing, pipeline and marine transportation businesses included in
ARCO's financial statements for the periods indicated.

Note 5 Sale of Certain Lower 48 Pipeline Assets

In order to obtain approval for the acquisition of ARCO by BP, the Federal
Trade Commission also required that ARCO sell certain Lower 48 pipeline
assets. The sale of those assets was completed in August 2000 for net proceeds
totaling approximately $314 million and ARCO recorded an after-tax gain on the
sale of approximately $8 million in the third quarter of 2000. The net book
value of the Lower 48 pipeline assets sold was approximately $304 million.

Note 7 Segment Information

Segment information has been prepared in accordance with SFAS No. 131,
"Disclosure about Segments of an Enterprise and Related Information." ARCO has
two reportable segments: exploration and production (E&P) and refining and
marketing (R&M). The segments were determined based upon types of products
produced/sold by each segment. Segment performance is evaluated based upon net
income, excluding interest expense.
  The E&P segment is an aggregation of several business units engaged in one
or more of the following: the worldwide exploration, development and
production of petroleum liquids (crude oil, condensate and natural gas
liquids) and natural gas; the purchase and sale of petroleum liquids and
natural gas, and prior to the sale discussed in Note 4, the transportation via
pipeline of petroleum liquids within the State of Alaska. The company's
investments in the LUKARCO joint venture and LUKOIL common stock are included
in the E&P segment as well.
  The R&M segment comprises the refining of crude oil, primarily from the
North Slope of Alaska; the marketing of petroleum products, primarily in the
West Coast region of the U.S.; and, prior to the sale discussed in Note 4, the
transportation of petroleum liquids and petroleum products via ocean-going
tankers, primarily between Alaska and the West Coast. The company's equity
investment in Zhenhai Refining and Chemical Company is included in the R&M
segment as well.
  Revenue from other operating segments is attributable to the pipeline
transportation and storage of petroleum liquids and petroleum products in the
48 contiguous United States and operations of an aluminum business.

Note 8 Acquisition of Union Texas Petroleum Holdings, Inc.

In June 1998, ARCO completed its tender offer for all outstanding common
shares of Union Texas Petroleum Holdings, Inc. (UTP) for approximately $2.5
billion, or $29 per share in cash. ARCO also purchased in a tender offer
1,649,500 shares of UTP's 7.14% Series A Cumulative Preferred Stock for
approximately $200 million, or $122 per share in cash. UTP was a U.S.-based,
non-integrated oil and gas company with substantially all of its oil and gas
producing operations conducted outside of the U.S. in the United Kingdom
sector of the North Sea, Indonesia, Venezuela and Pakistan.
  The acquisition was accounted for as a purchase. The results of operations
of UTP are included in the consolidated financial statements of ARCO as of
July 1, 1998. The cost of the acquisition was allocated on the basis of the
estimated fair value of the assets acquired and liabilities assumed and there
are no contingencies or other matters that could affect the allocation of the
purchase cost.
  Liabilities assumed included employee termination costs of $90 million and
other costs associated with the merging of UTP's businesses into ARCO's
operations, such as lease and other contract cancellation costs, totalling
$18 million, of which $7 million were non-cash charges. All cash costs were
paid by December 31, 2000.
  The following unaudited pro forma summary presents information as if UTP had
been acquired as of the beginning of ARCO's fiscal year 1998. The pro forma
amounts include certain adjustments, primarily to recognize depreciation,
depletion and amortization based on the allocated purchase price of UTP
assets, and do not reflect any benefits from economies which might be achieved
from combining operations. The pro forma information does not necessarily
reflect the actual results that would have occurred nor is it necessarily
indicative of future results of operations of the combined companies:

Note 9 Discontinued Operations

Coal
In the second quarter of 2000, ARCO disposed of its remaining coal assets in
Australia. Upon the sale of those assets, a provision originally established
in 1998 for the estimated loss on sale of U.S. and Australian coal assets was
reduced resulting in an after-tax gain of $89 million.

                                      49


                  Notes to Consolidated Financial Statements

  In the first quarter of 1999, ARCO disposed of its interests in two
Australian coal mines. ARCO disposed of its 80% interest in the Gordonstone
coal mine and its 31.4% interest in the Blair Athol Joint Venture. At
December 31, 1999, the carrying value of the remaining Australian coal assets
was $67 million and was included as net assets of discontinued operations on
the balance sheet.
  In June 1998, ARCO disposed of its U.S. coal operations in a transaction
with Arch Coal. Operations disposed of included the Black Thunder and Coal
Creek mines in Wyoming, the West Elk mine in Colorado, and ARCO's 65% interest
in three mines in Utah. The Colorado and Utah mines were sold outright. ARCO
contributed its Wyoming coal operations and Arch Coal transferred various of
its coal operations into a new joint venture that is 99% owned by Arch Coal
and 1% owned by ARCO.
  In 1998, ARCO recorded a $92 million provision for the estimated loss on the
disposal of the U.S. and Australian coal assets. In 1999, upon completion of
the Australian sales noted above, the provision was reduced, resulting in an
after-tax gain of $22 million.

Chemicals
In July 1998, ARCO tendered its entire interest of 80 million shares of ARCO
Chemical Company common stock to Lyondell Chemical Company (Lyondell) for
$57.75 per share, or total cash proceeds of approximately $4.6 billion. After
deferral of $313 million of the pre-tax gain, ARCO recorded an after-tax gain
of approximately $1.1 billion in 1998 from the sale of the shares.
  The $313 million deferral represents the estimated discounted present value
of the difference, over the remaining term of an above-market MTBE contract
between ARCO and ARCO Chemical, between the contract price and the spot market
price for MTBE. The deferral is being amortized over the remaining term of the
contract, ending in 2002, on the basis of annual volume over total contracted
volume.
  In 1999, adjustments for tax benefits resulted in the recording of an addi-
tional after-tax gain of $59 million on the disposition of ARCO Chemical.
  At the time of the acquisition of UTP, ARCO determined it would sell UTP's
petrochemical business. Accordingly, in 1998, ARCO recorded a $33 million af-
ter-tax provision for loss on the sale of the assets. If depreciation had not
been suspended for the last six months of 1998, the petrochemical business
would have had a loss of $5 million for 1998. In March 1999, ARCO sold the UTP
petrochemical business and recorded an additional loss of $4 million.
  Revenues and net income from discontinued operations were as follows:

                  Notes to Consolidated Financial Statements

Note 10 Accounting Changes

Effective January 1, 1999, ARCO adopted Statement of Position (SOP) 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use," and SOP 98-5, "Reporting on the Costs of Start-up Activities."
SOP 98-5 states that costs of start-up activities should be expensed as
incurred. The implementation of SOP 98-5 did not have a material cumulative
effect on ARCO's results of operations (less than $0.01 per share). SOP 98-1
establishes criteria for determining how the costs of developing or obtaining
internal-use computer software should be accounted for. SOP 98-1 was adopted
prospectively and therefore there was no cumulative effect of adoption.

Note 11 Restructuring Costs

During 2000 the company recorded restructuring costs of $742 million before
tax in conjunction with the merger into BP (See Note 1), comprised of the
following:

Personnel termination costs relate to the severance of approximately 2,050
employees, primarily at the corporate headquarters and Vastar, a technical
support center in Texas, and various operating units worldwide. This did not
include costs related to the termination of foreign national employees. This
represents specific employee terminations identified as of December 2000;
further charges may be necessary in future periods if additional terminations
become known.
  Additionally, approximately 700 terminations were identified related to
Alaskan oil and gas and lower 48 pipeline operations sold during 2000. These
costs were included as part of the net gain on sale of those operations.
  The following table summarizes the charges related to the terminations that
resulted from ARCO's merger into BP:

(a) Severance payments and ancillary benefits such as relocation and
    outplacement.
(b) Net increase in pension benefits to be paid from assets of qualified
    plans.
(c) Net increase in non-qualified pension benefits and other postretirement
    benefits to be paid from Company funds.

Through December 31, 2000, approximately 1,530 employees have been terminated
and approximately $84 million of severance and ancillary benefits have been
paid and charged against the accrual. Payments made do not necessarily
correlate to the number of terminations due to the ability of terminees to
defer receipt of certain payments. The remaining severance and ancillary
benefits are expected to be paid by the second quarter 2002.
  A reserve of $88 million was established for office space and facilities,
primarily in Los Angeles and Houston, that will be vacated with no future
economic benefit. Cash payments will be made through the remaining terms of
the leases, the longest (and largest) of which extends to 2012.

                  Notes to Consolidated Financial Statements

  The charge of $98 million for stock-related compensation related to
compensation benefits from contingent restricted stock and dividend share
credits on stock options granted to executives and key employees. The
benefits, which ordinarily would have been reported as compensation expense in
future periods, were accelerated upon the change of control of the company.
  Merger costs represent costs directly related to the consummation of the
merger, primarily for investment and legal consultants, which have been paid.
  The remainder of the unusual items charge is comprised of shutdown costs
(such as foreign national terminations and other location-specific costs) for
offices in the United Kingdom and other worldwide locations.
  Through December 31, 1999, the company had previously established reserves
totaling $251 million for the costs of terminating 1,250 employees. $103
million related to short-term benefits such as severance payments and
ancillary benefits such as relocation and outplacement; $148 million related
to pension and other postretirement benefits. Through December 31, 2000,
approximately 1,200 employees have been terminated and approximately $97
million of severance and ancillary benefits have been paid and charged against
the short-term benefit accrual. The remaining employees will terminate under
the 2000 merger change of control severance program with the previously
established reserves deemed adequate.

Union Texas Petroleum Holdings, Inc. (UTP) Restructure.
Through December 31, 2000, the company established a $90 million provision for
the termination of 357 employees from the integration of UTP into ARCO's
operations. As of December 31, 2000, ARCO had terminated 355 of the employees
and had paid out a total of $85 million in severance benefits.

Note 12 Inventories

Inventories are recorded when purchased, produced or manufactured and are
stated at the lower of cost or market. In 2000, approximately 75% 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:



Millions                              2000     1999

                                  =================


The excess of the current cost of inventories over book value was
approximately $236 million and $246 million at December 31, 2000 and 1999,
respectively.

Note 13 Investments

At December 31, 2000 and 1999, investments in debt securities were primarily
composed of U.S. Treasury securities and corporate debt instruments.
Maturities generally ranged from one month to ten years. These investments are
classified as short or long term depending on maturity. ARCO's investments in
LUKOIL common stock and Zhenhai Refining and Chemical Company convertible
bonds were included in other investments and long-term receivables. At
December 31, 2000 and 1999, all investments were classified as available-for-
sale and were reported at fair value, with unrealized holding gains and
losses, net of tax, reported in accumulated other comprehensive income.

Expenses for maintenance and repairs for 2000, 1999 and 1998 were $244
million, $292 million and $387 million, respectively.
  In 2000, ARCO recorded an impairment charge of $286 million before tax
primarily related to several Latin American oil fields along with smaller
impairments of properties in the United States and Europe.

Note 15 Short-term Borrowings and Bank Credit Facilities

Notes payable consist primarily of ARCO's commercial paper issued to a variety
of financial investors and institutions and any amounts outstanding under ARCO
credit facilities. There were no short-term notes payable outstanding at
December 31, 2000. The weighted average interest rate on notes payable
outstanding at December 31, 1999 was 6.0%. In April 2000, following the
acquisition of ARCO by BP, ARCO's $3.0 billion unused committed bank credit
facility was terminated.

April 20, 2010 Putable/Callable April 20, 2000. In 1998, Vastar also entered
into an interest rate swap covering the Putable/Callable Notes, which
effectively changed the 6% fixed rate to a floating rate. The effective
interest rate paid on these notes, which were redeemed in 2000, was 6.17%. The
financial impact of swaps in 1999 and 1998 was immaterial.

Note 18 Financial Instruments and Fair Value

ARCO does not hold or issue financial instruments for trading purposes.
  Prior to the acquisition of ARCO by BP, ARCO entered into various types of
foreign currency forward, option and swap contracts. Foreign currency forward
contracts were 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 related to
overseas operations.
  Gains and losses on foreign currency forward contracts covering anticipatory
cash flows were recognized currently as other income or expense. Gains and
losses on foreign currency swaps associated with intercompany debt were
recognized currently in income and offset foreign exchange gains and losses on
the underlying intercompany loans. Gains and losses on other foreign currency
contracts were generally deferred and offset the transactions being hedged.
  Prior to the acquisition of ARCO by BP, ARCO also used various hedging
arrangements to manage the exposure to price risk for future natural gas and
crude oil transactions. Gains and losses resulting from those transactions
were 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 was delivered.

  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; ARCO does not
anticipate nonperformance by the counterparties.

Note 19 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.
  ARCO has also guaranteed all of LUKARCO's obligations associated with the
Caspian Pipeline project, which amount to 25% of all funding requirements for
this project. The current estimates of total project funding requirements are
between $2.4 to $2.6 billion.
  Following the March 1989 Exxon Valdez oil spill, numerous federal, state and
private plaintiff lawsuits were brought against Exxon (now ExxonMobil),
Alyeska Pipeline Service Company (Alyeska) and Alyeska's owner companies,
including ARCO Transportation Alaska, Inc., owned by ARCO until the FTC-
mandated sale to Phillips Petroleum in April 2000. While all of the federal,
state and private plaintiff lawsuits have been settled, certain issues
relating to liability for the spill remain unresolved between Exxon and
Alyeska (including its owner companies).
  Lawsuits, including purported class actions and actions by governmental
entities, are pending or threatened against ARCO and others seeking damages,
abatement of housing units, and compensation for medical problems arising out
of the presence of lead-based paint in certain housing units. ARCO is unable
to predict the scope or amount of any such liability.
  The State of Montana, along with the United States and the Salish and
Kootenai Tribes, have been seeking recovery from ARCO for alleged injuries to
natural resources resulting from mining and mineral processing businesses
formerly operated by Anaconda. In 1998, ARCO entered into two consent decrees,
which were approved by the court in 1999,

                  Notes to Consolidated Financial Statements

settling all of the natural resources damage claims of the United States and
the tribes and the bulk of such claims of the State of Montana. Remaining for
disposition are the State's claims for $206 million of restoration damages at
three sites.
  ARCO is subject to other loss contingencies pursuant to federal, state and
local environmental laws and regulations that require ARCO to do some or all
of the following:
  . Remove or mitigate the effects on the environment at various sites from
    the disposal or release of certain substances;
  .Perform restoration work at such sites; and
  .Pay damages for loss of use and non-use values.
The federal agencies involved with the sites include the Department of the
Interior, Department of Justice and Environmental Protection Agency.
Environmental liabilities include personal injury claims allegedly caused by
exposure to toxic materials manufactured or used by ARCO.
  ARCO is currently involved in assessments and cleanups under these laws at
federal- and state-managed sites as well as other clean-up sites including
service stations, refineries, terminals, third-party landfills, former nuclear
processing facilities, sites associated with discontinued operations and sites
previously owned by ARCO or predecessors. This comprises 148 sites for which
ARCO has been named a potentially responsible party (PRP), along with other
sites for which no claims have been asserted. 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 responsibility varies from
sole responsibility to very little responsibility.
  ARCO may in the future be involved in additional assessments and cleanups.
Future costs depend on unknown factors such as:
  .Nature and extent of contamination;
  .Timing, extent and method of remedial action;
  .ARCO's proportional share of costs; and
  .Financial condition of other responsible parties.
  The environmental remediation accrual is updated annually, at a minimum, and
at December 31, 2000 was $1,098 million (total of short and long-term compo-
nents). During 2000, management of the Company assessed the estimated future
costs to remediate all of the Company's environmental sites and concluded that
its best estimate of the cost to remediate such sites was greater than previ-
ously recorded. As a result the environmental reserve was increased by $521
million during 2000, of which $274 million was recognized during the fourth
quarter. As these costs become more clearly defined, they may require future
charges against earnings.
  Approximately 85% 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. One
site represented 13% of the total accrual. No other site represented more than
8% of the total accrual. Substantially all amounts accrued are expected to be
paid out over the next 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 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.

                                      57


                  Notes to Consolidated Financial Statements

  The operations and consolidated financial position of ARCO continue to be
affected by domestic and foreign political developments as well as
legislation, regulations and litigation pertaining to restrictions on
production, imports and exports, tax increases, environmental regulations,
cancellation of contract rights and expropriation of property. Both the
likelihood of such occurrences and their overall effect on ARCO vary greatly
and are not predictable.
  These uncertainties are part of a number of items that ARCO has taken and
will continue to take into account in periodically establishing reserves.

Note 21 Employee Benefit Plans

ARCO and its subsidiaries sponsor numerous postretirement benefit plans.
Defined benefit pension plans (Pension) provide to substantially all employees
pension benefits based on years of service and the employee's compensation,
primarily during the last three years of service. Defined postretirement
benefit plans (Other) provide health care and life insurance benefits to
substantially all employees who retire with ARCO having rendered the required
years of service, and to their spouses and eligible dependents. ARCO pays for
the cost of a benchmark health maintenance organization with employees
responsible for the differential cost, if any, of their selected option. Life
insurance benefits are partially paid for by retiree contributions, which vary
based upon coverage chosen by the retiree. ARCO and BP have the right to
terminate or modify the plans at any time.

  For measurement purposes, a 7% annual rate of increase in the per capita
cost of health care benefits was assumed for 1997 to 2000, 15% for 2001, and
10% for 2002, after which the rate was assumed to decrease to 5% and remain at
that level thereafter.
  A one-percentage-point change in assumed health care cost trend rates would
have the following effects:

Included in pension obligations are liabilities related to non-qualified pen-
sion plans that provide retirement benefits in excess of current Internal Rev-
enue Service maximums. The company also has deferred compensation plans that
permit executives, outside directors and key employees to defer a portion of
their compensation (including bonuses). Amounts deferred accrue interest at a
defined rate and are not included as pension obligations. The liability for
deferred compensation and interest thereon was $638 million and $343 million
at December 31, 2000 and 1999, respectively, and is included in "other de-
ferred liabilities and credits" on the balance sheet. The liabilities for non-
qualified pension plans and deferred compensation are unfunded based on defi-
nitions of generally accepted accounting standards. However, to assist in
funding these liabilities, the company has invested in corporate-owned life
insurance policies. The cash surrender value of the policies supporting these
liabilities was $630 million and $572 million at December 31, 2000 and 1999,
respectively, and is included in "deferred charges and other assets" on the
balance sheet.

purchase certain leased properties.

Note 23 Stock Options

  Options to purchase shares of ARCO's common stock have been granted to exec-
utives, outside directors and key employees. The exercise price of each option
is equal to the fair market value of common stock at the date of grant. These
options become exercisable in varying installments and expire 10 years after
the date of grant. Options granted vest equally over three years. Effective
upon consummation of the merger, all options to purchase ARCO common stock
were converted into options to purchase BP ADSs, pursuant to the merger agree-
ment. Transactions during 2000, 1999 and 1998 were as follows:

At December 31, 2000, there were no outstanding options to purchase ARCO com-
mon stock.
  ARCO applies APB No. 25 in accounting for its fixed stock options. Accord-
ingly, no compensation cost has been recognized for options granted. The fol-
lowing table reflects pro forma net income and earnings per share had the com-
pany elected to adopt the fair value method under SFAS No. 123:


                                                  2000       1999       1998
- ------------------------------------------------------------------------------
                                                          
Net income:
As reported                                     $3,026  $   1,422  $     452
Pro forma                                       $2,989  $   1,407  $     440
Earnings per share (diluted):
As reported                                          -  $    4.33  $    1.40
Pro forma                                            -  $    4.29  $    1.36


These pro forma amounts may not be representative of future disclosures since
the estimated fair value of stock options would be amortized to expense over
the vesting period, and additional options may be granted in future years.
  ARCO awards contingent restricted stock to executives and key employees.
Contingent restricted stock may be converted to performance-based restricted
stock in various multiples depending on attainment of certain performance
criteria over a specified evaluation period. Restricted stock ultimately
issued is subject to a two-year restriction on transfer.
  There were no new grants of contingent restricted stock in 2000. During
1999, 236,412 shares of contingent restricted stock were awarded at a weighted
average price of $56.81, net of forfeitures and retirements, and with varying
evaluation periods. During 2000, 1999 and 1998, 107,718 shares, 28,696 shares
and 135,180 shares of performance-based restricted stock were issued at
weighted average prices of $68.81, $56.81 and $73.93, respectively.   As of
the date of the merger with BP, restrictions on all outstanding contingent and
performance-based restricted shares were removed. The removal of these
restrictions resulted in restricted stock expense of $18 million in 2000. In
1999 and 1998, $21 million and $10 million was recognized as expense for
performance-based restricted stock, respectively.

                  Notes to Consolidated Financial Statements
  Holders of options granted prior to 1997 accrue dividend share credits
(DSCs) on all shares under option. The amount of DSCs accrued is determined
based upon the quarterly dividend rate and fair market value of ARCO common
stock as of each quarterly record date. Upon exercise of options, holders
receive additional shares of common stock equal to DSCs accumulated. A summary
of ARCO's DSC activity was as follows:

Excluded from the Consolidated Statement of Cash Flows for the year ended
December 31, 1998 was the issuance of 2,725,030 shares of ARCO common stock to
a consolidated subsidiary in exchange for certain property, plant and
equipment owned by the subsidiary. The transaction was recorded at fair market
value.
  In October 1998, through a three-way exchange involving ARCO, Vastar and
Mobil, ARCO disposed of its California heavy crude properties. In the
transaction, an ARCO subsidiary holding the California properties traded the
California properties for Mobil's interests in producing fields and
exploration acreage in the Gulf of Mexico. Vastar then purchased the ARCO
subsidiary holding the Gulf of Mexico properties for $437 million, including
the assumption of $300 million of debt which was repaid in first quarter 1999.

Note 26 Foreign Currency Transactions

Note 31 Unaudited Subsequent Event

On March 28, 2001, ARCO's Board of Directors announced that it had elected to
redeem all of the outstanding $3.00 and $2.80 Preference Shares on April 27,
2001.
  Shareholders of the $3.00 Cumulative Convertible Preference Stock will
receive a total cash payment equal to the market value of 22.304 ADSs, as
determined by the average NYSE closing prices for the BP ADSs on the last four
business days before the April 27th redemption date. The number 22.304
represents the number of BP ADSs into which each share of the $3.00 Preference
Stock is convertible through April 20, 2001.
  Shareholders of the $2.80 Cumulative Convertible Preference Stock will
receive a total cash payment equal to the market value of 7.872 BP ADSs, as
determined by the average NYSE closing prices for the BP ADSs on the last four
business days before the April 27th redemption date. The number 7.872
represents the number of BP ADSs into which each share of the $2.80 Preference
Stock is convertible through April 20, 2001.

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 which 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.
  Petroleum reserves are estimated by the Company's engineers. The estimates
include reserves in which ARCO holds an economic interest under production-
sharing and other types of operating agreements with foreign governments.
  Reserves attributable to certain oil and gas discoveries were not considered
proved as of December 31, 2000 due to geological, technical or economic
uncertainties. Proved reserves do not include amounts that may result from
extensions of currently proved areas or from application of enhanced recovery
processes not yet determined to be commercial in specific reservoirs. Proved
reserves also do not include any reserves attributable to ARCO's 8% interest
in LUKOIL, a Russian oil company. Natural gas liquids comprise 13% of
petroleum liquid proved reserves.
  ARCO has no long-term supply contracts to purchase petroleum liquids or
natural gas from foreign governments.
  The most significant activity during 2000 was the sale of all ARCO's Alaskan
oil and gas properties. Changes in proved reserves for the years ended Decem-
ber 31 were as follows:

                     Supplemental Information (Unaudited)


  ARCO is a contractor to an affiliate of the Venezuelan government under six
risked service contracts. ARCO, either solely or with partners, is responsible
for providing capital and technology for the redevelopment of the fields along
with operating existing production. In exchange for providing and funding
overall operation and field development, ARCO is paid a per-barrel service fee
to cover reimbursement of costs plus profit. There are two components to the
fees, which include (1) a set fee for contractual baseline production and (2)
a fee for incremental production. The fee for incremental production is based
on a sliding scale incentive mechanism, which is indexed to a basket of
international oil prices and overall field profitability.
  Proved reserves and production quantities for Venezuelan operations are
recorded based on ARCO's net working interest in each of the contract areas,
"net" meaning reserves excluding royalties and interests owned by others per
the contractual arrangements. The Venezuelan government maintains full
ownership of all hydrocarbons in the fields.
  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 since the beginning of the
last fiscal year of total ARCO reserve estimates furnished to federal
government agencies or commissions which vary from those reported to the SEC.
  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:

The difference between the above results of operations and the amounts
reported for exploration and production segment net income in Note 7 of Notes
to Consolidated Financial Statements is primarily gains or losses on asset
sales, the exclusion of non-producing exploration and production units
(Alaskan pipelines, technical support), minority interest adjustments and
restructuring costs related to oil and gas operations.

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 pre-tax 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.

     COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

  Executive officers and directors and "beneficial owners" of more than ten
percent of the common stock or either class of the Preference Stocks must file
initial reports of ownership and reports of changes in ownership with the
Securities and Exchange Commission (SEC) and the New York Stock Exchange
pursuant to Section 16(a).
  None of the executive officers or directors own any equity securities of
ARCO. We have reviewed the reports and written representations from the
executive officers and directors. Due to inadvertent oversights, certain
employees of BP who were elected as officers and Directors of ARCO following
the merger failed to file timely reports on Form 3. In all cases, the late
report on Form 3 showed that no equity securities of ARCO were owned by any of
these employees of BP. On July 18, 2000, Form 3s were filed by the following
persons elected to their positions on April 18, 2000: Robert D. Agdern,
director and President; John F. Campbell, director and Vice President; James
G. Nemeth, Director and Vice President; Eileen A. Kamerick, Chief Financial
Officer and Vice President; David H. Welch, Executive Vice President; and
Roger E. Williams, Executive Vice President. On January 4, 2001, Form 3s were
filed by the following persons elected to their positions on the date
indicated in parentheses following their names: Robert A. Malone, President
(November 13, 2000); Donald E. Packham, Director (September 18, 2000); and Ian
Springett, Chief Financial Officer and Vice President (October 2, 2000).

ITEM 11.  EXECUTIVE COMPENSATION

      PRE-MERGER AND CHANGE OF CONTROL COMPENSATION OF CERTAIN OF ARCO'S
                           FORMER EXECUTIVE OFFICERS

                Change of Control Benefits Received by Certain
                        Former ARCO Executive Officers

General

As a result of the merger of ARCO into BP, effective April 18, 2000, ARCO
employees terminated following the merger, including the former executive
officers became eligible for the benefits described herein. In accordance with
the proxy rules under the Securities & Exchange Act of 1934, described below
are the change of control benefits received by three former executive officers
of ARCO named below.

ARCO's Change of Control Arrangements Effective Upon Merger

Pursuant to the merger agreement between BP and ARCO, the consummation of the
merger was considered a change of control within the meaning of ARCO's various
change of control arrangements. BP and ARCO agreed that all of the change of
control provisions would become operative immediately following the
consummation of the merger. The merger agreement also specifically provided
that all ARCO stock-related benefits automatically would be converted into the
right to purchase or receive BP Amoco ordinary shares, which were issued in
the form of BP ADSs.

Severance Benefits
The employment of all executive officers was terminated following the change
of control. Severance benefits included:

  (1) an enhancement of the normal retirement benefit, known as the "5+5" be-
      cause the enhancement adds five years of age and five years of service
      to the normal retirement benefit, payable in the form of a lump sum or
      an annuity,
  (2) a severance benefit equal to the product of one and one-half weeks of
      pay for each year of continuous service, capped at 36 weeks of pay,
      payable in a lump sum,
  (3) payment of the executive's pro-rated target Annual Incentive Plan (AIP)
      award, and
  (4) the continuation of health, dental and life insurance coverage for 36
      months.


Other Change of Control Benefits
All executive officers, regardless of post-merger employment status, received
the following benefits upon the merger:

  (1) crediting of prospective dividend share credits (future undeclared and
      unpaid dividends),
  (2) vesting of a pro-rated number of shares in respect of contingent stock
      awards,
  (3) lifting of restrictions on restricted stock, and
  (4) vesting of previously unvested stock options, other than options issued
      after April 1, 1999.

  In addition to the change of control-related benefits, upon termination of
employment, each of the named executive officers received normal retirement
benefits, including payments under the retirement plan, the supplementary ex-
ecutive retirement plan and the executive deferral plan, and continued to hold
previously vested options and other stock rights. The date of actual receipt
of certain of the retirement benefits depended on an individual's age and
length of service at the time of termination and on individual payout elec-
tions.
  Prospective Dividend Share Credits (DSCs). Under ARCO's Executive Long-Term
Incentive Plan (LTIP), for all option grants made prior to 1997, DSCs are
credited to an optionee's account whenever dividends are declared on

                                      77


ARCO common stock. The number of credits is computed by multiplying the
dividend rate per share times the sum of (1) the number of eligible options
and (2) the number of DSCs then accrued and then dividing the resulting number
by the stock price on the dividend record date. Upon exercise of options
having the right to DSCs, the option holder is entitled to receive an
additional number of shares equal to the number of DSCs then accrued with
respect to the options being exercised. The number of prospective DSCs yet to
be accrued for the remaining term of a particular option grant were
accelerated and vested effective April 17, 2000.
  Conversion and Vesting of Contingent Restricted Stock. Under the LTIP, since
1997, grants of contingent restricted stock have been awarded having one- to
three-year performance periods. At the conclusion of the performance period,
grants of restricted stock are made in amounts ranging from zero to three
times the number of contingent shares awarded, depending on ARCO's performance
relative to a peer group of other oil and gas companies. Effective April 17,
2000 upon the change of control, a prorated number of shares of common stock
were granted based on the portion of the performance cycle completed for the
outstanding 1998 and 1999 grants of contingent restricted stock.
  Restricted Stock. Under the LTIP, performance based restricted stock was
granted in 1999 and 2000, with each grant having a two-year restricted period.
Prior to the merger, dividends paid after the grant date were reinvested in
additional restricted stock. The restricted stock vested immediately upon the
consummation of the merger.
  Unvested Options. All unvested options granted prior to April 1, 1999, none
of which had the right to DSCs, vested on the merger date. The unvested
options granted for 1999 in February 2000 did not vest on the merger, nor did
they have the right to DSCs. In addition, the net value of each executive's
vested options (and related DSCs) had accrued to his or her account regardless
of the change of control provisions.

Indemnification, Directors' and Officers' Insurance
BP has agreed to indemnify and provide directors' and officers' liability
insurance through April 18, 2006 for individuals who were directors or
officers of ARCO prior to April 18, 2000 for their acts or omissions in that
capacity.

Notes to Summary Compensation Table

(1) All information in this chart for the year 2000 covers the period January
    1-June 1, 2000. Messrs. Bowlin and Wiley and Mrs. Knowles resigned as
    officers and directors of ARCO on April 18, 2000 concurrently with the
    merger of ARCO with BP Amoco, and retired from employment with ARCO on June
    1, 2000.

(2) Other Annual Compensation. "Other Annual Compensation" includes amounts of
    tax gross-ups for financial counseling reimbursements and for certain other
    items reported under IRS rules as imputed income.

(3) Types of Option Grants. Prior to the merger of ARCO into BP Amoco, options
    exercisable for common stock of ARCO were issued under ARCO's Executive
    Long-Term Incentive Plan (LTIP). All information herein relates to the
    number of options for ARCO common stock. Pursuant to the merger agreement,
    all options for ARCO common stock became converted into rights to BP ADSs.
    Two types of option grants were made under the LTIP for the years 1998 and
    1999. No option grants were made for 2000 in 2001:

   . re.u.ar a..ua. optio. .ra.ts made i. Fe.ruary of each year for the

Notes to Pre-Merger and Change of Control Summary Compensation Table

Computation of Dividend Share Credits.  Prior to the merger, dividend share
   credits were allocated to an optionee's account whenever dividends were
   declared on common stock. The number of credits is computed by

   . multiplying the dividend rate per share times

    (1) the number of eligible options plus
    (2) the number of dividend share credits then accrued

   . and dividing the resulting number by the fair market value of the
     common stock on the dividend record date.

   Prior to the merger the value of the accrued dividend share credits was not
   fixed until the eligible options were exercised. The value, which was
   received in shares of stock or cash, was equal to the number of accrued
   credits allocated to the options being exercised multiplied by the fair
   market value of the common stock on the date of exercise. Until the option
   exercise date the optionee had no right to their value. Following the
   merger, all dividend share credits were vested and were converted into BP
   ADSs.

(4) Restricted Stock Awards. The Executive Long-Term Incentive Plan was
    amended in 1997 to provide for grants of restricted stock. Prior to the
    merger participants could earn restricted stock based on ARCO's total
    return to shareholders as measured against that of a peer group. The table
    shows the normal lifting of restrictions on the 1998 grant of restricted
    stock on February 23, 2000, before the re-investment of dividends.

  On the merger date, restrictions were also lifted on the 1999 and 2000
  grants of restricted stock. The fair market value of ARCO Common Stock
  converted to ADSs on April 18, 2000, was $47.75 per ADS. The values of the
  restricted shares to each of the named officers on this date were:


                          
     Mr. Bowlin   35,025 shares $  1,672,446
     Mr. Wiley    13,648 shares $    651,716
     Mrs. Knowles 13,648 shares $    651,716


  Values for 1998 and 1999 Grants. The value of the shares of restricted
  stock awarded for the years 1998 and 1999, based on the fair market value
  of $79.59 per share on April 17, 2000, for each named officer is shown
  below:


               
     Mr. Bowlin   $  7,698,732
     Mr. Wiley    $  3,178,082
     Mrs. Knowles $  2,891,208


  Acceleration and Vesting of Outstanding Contingent Restricted Stock
  Following Change of Control. Pursuant to the change of control provisions
  in the merger agreement, outstanding shares of contingent restricted ARCO
  stock were converted into ADSs of BP effective May 2, 2000. The value of
  the total ADSs granted, based on a fair market value of $51.4375 per ADS,
  to each of the named officers was as follows:


               
     Mr. Bowlin   $  5,175,258
     Mr. Wiley    $  2,194,757
     Mrs. Knowles $  1,887,883

Notes to Option Exercise Table

(1) Prior to the merger, options awarded prior to 1997 carried with them the
    right to a potential payment in respect of dividend share credits. See
    Note (3) of Notes to Pre-Merger Summary Compensation Table.

(2) Closing price of ARCO common stock on April 17, 2000 was $79.59.

(3) For illustrative purposes only, set forth below are the hypothetical
    aggregate values of both in-the-money exercisable options and
    unexercisable options, including the value of the dividend share credits
    accrued through April 17, 2000, in respect of options granted prior to
    1997. These calculations assume these options were exercised on April 17,
    2000, at the closing price of $79.59. All unexercisable in-the-money
    options were granted in 1997 or later and therefore do not carry with them
    the right to dividend share credits.

Notes to Post-Merger Summary Compensation Table

(1) Annual Compensation. None of the named executive officers received any
    compensation from ARCO for their services. All of the named executive
    officers are employees of BP or its wholly owned subsidiaries other than
    ARCO or Vastar. Any amounts shown for salary or bonus represent the pro
    rata portion of the amount paid to the officer in his capacity as a BP
    employee in respect of the portion of his time allocable to activities as
    an officer of ARCO. The pro rated amount for each of the named officers
    was less than $100,000 and not required to be disclosed pursuant to SEC
    rules. Since BP became the owner of all of the common stock of ARCO
    following the merger, BP determined that the organization of its business
    operations obviated the need for a chief executive officer of ARCO. BP
    organizes its businesses according to functional relationships and not
    according to corporate identity.

(2) Long-Term Compensation. No amounts are shown, because all equity-related
    long-term compensation was payable in BP equity securities and not in ARCO
    equity securities.

(3) All Other Compensation. Any amounts payable in respect of other employee
    benefits were paid pursuant to BP benefit plans, and hence are not shown
    in this chart.

Compensation of Directors

None of the members of the Board of Directors receives any compensation from
ARCO for their services. All of the members of the Board are employees of BP
or wholly owned subsidiaries other than ARCO or Vastar.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

                            Controlling Shareholder

  BP is the controlling shareholder of ARCO because it owns all of the
outstanding common stock of ARCO.

                          Related Party Transactions

  Sales to and purchases from BP or its subsidiaries consisted primarily of
the sale or purchase of petroleum liquids and natural gas. Related party
interest in 2000 relates to an intercompany receivable from BP that has been
outstanding since the sale of Alaskan operations in the second quarter 2000.
Pursuant to the terms of the Merger Agreement, BP has assumed certain
obligations of ARCO, all relating to compensation and other employee benefit
matters, following the merger. See Note 3 of Notes to Consolidated Financial
Statements.
