THE COMBINATION OF BP AMOCO AND ARCO

Introduction

  On April 1, 1999 the Board of BP Amoco announced that it had reached agreement
on a proposed  combination (the  combination)  with Atlantic  Richfield  Company
(ARCO) of Los Angeles.

  The  agreement   relating  to  the  proposed   combination   (the  Combination
Agreement),  approved by the boards of both BP Amoco and ARCO,  provided for all
common  shareholders  of ARCO,  with the  exception of BP Amoco,  ARCO or any of
their subsidiaries, to receive 9.84 BP Amoco ordinary shares of US$ 0.25 each in
the form of BP Amoco  American  Depositary  Shares (ADSs) or, at the election of
the  shareholder,  BP Amoco 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 Amoco of new common shares equal in number to the Cancelled ARCO Shares by
a newly enlarged ARCO formed by a statutory merger of Prairie Holdings,  Inc. (a
direct wholly owned  subsidiary of BP Amoco) into and with ARCO.  Any right to a
fraction  of a BP Amoco  ADS or an odd lot of less  than  six BP Amoco  ordinary
shares would be satisfied by a cash payment. Both ARCO and BP Amoco shareholders
voted  overwhelmingly in favour of the combination at shareholders'  meetings on
August 30, 1999 and September 1, 1999, respectively.

  BP Amoco and ARCO  announced  in early  November  1999  that they had  reached
provisional  agreement  with the  Alaskan  State  Governor on a package of asset
disposals and other measures  designed to secure Alaskan  government  acceptance
for the proposed combination of the two companies. The provisional agreement was
finalized  into an  agreement  with the State of  Alaska  (the  Alaskan  Charter
Agreement) made in early December 1999.

  On February 4, 2000 the US Federal Trade Commission (FTC) filed a complaint in
the US District  Court (the Court)  seeking a preliminary  injunction to prevent
closing of the combination.  The Attorney Generals for the States of California,
Oregon and Washington (the Western  States) also filed  complaints with the same
Court.  The  Attorney  General  for the  State of  Alaska  joined  in the  Court
proceedings  in support of the  combination.  On March 15, 2000 it was announced
that the FTC,  the Western  States,  the State of Alaska,  ARCO and BP Amoco had
agreed to  suspend  the Court  proceedings,  pending  discussions  for a consent
order.

  On March 15, 2000 ARCO  entered  into an  agreement  with  Phillips  Petroleum
Company  (Phillips) for the sale of its Alaskan  businesses (see Sale of Alaskan
Businesses below).

  On March  15,  2000 BP Amoco  announced  that it was at an  advanced  stage in
discussions  with the FTC on the  combination  and was  hopeful of  obtaining  a
consent order within a few weeks allowing the Company to close the combination.

  On March 23, 2000 BP Amoco and ARCO jointly  agreed to extend the  termination
date of the Combination Agreement from March 31, 2000 to June 30, 2000.

  On March 24, 2000  ExxonMobil  Corporation  (ExxonMobil)  filed a Complaint in
State Court,  Los Angeles,  seeking a  preliminary  injunction  and other relief
against  BP Amoco,  ARCO and  Phillips  to  prevent  the sale of ARCO's  Alaskan
businesses to Phillips referred to below.

  On April 13, 2000 BP Amoco, ExxonMobil,  ARCO and Phillips announced that they
had reached an agreement (the agreement) to resolve  outstanding issues relating
to the  ownership  and  operation  of the  Prudhoe  Bay Unit (PBU) and the Point
Thompson  Unit in  Alaska.  The  agreement  will  align  the  respective  equity
interests  of BP  Exploration  (Alaska)  Inc.,  ExxonMobil  and Phillips (as the
purchaser of ARCO's  Alaskan  businesses)  in the Prudhoe Bay Unit, and provides
for a single operator at the PBU.

  The aligned oil and gas interests among the major owners will be 26.7 per cent
for BP Exploration (Alaska),  36.8 per cent for ExxonMobil and 36.5 per cent for
Phillips.  BP Exploration  (Alaska),  current operator of the Western  Operating
Area in the Prudhoe Bay Unit, will become the single operator. ExxonMobil and BP
Exploration  (Alaska)  Inc.  have also agreed to work  towards  alignment in the
Point  Thomson  field  area  with  respective  interests  of 45 per  cent for BP
Exploration and 55 per cent for Exxon Mobil.

<PAGE>
  In  addition,  the  agreement  resolved  the issues  that had  resulted in the
Complaint filed by ExxonMobil in State Court, Los Angeles seeking to prevent the
sale of ARCO's Alaskan businesses to Phillips discussed below.

  On April 16, 2000 BP Amoco and ARCO announced that they had received clearance
from the FTC for the  combination of the two companies and the  combination  was
completed on April 18, 2000.

Sale of Alaskan Businesses

  On  March  15,  2000  ARCO  entered  into an  agreement  to sell  its  Alaskan
businesses to Phillips for  approximately  $6.5 billion cash subject to purchase
price  adjustments  (and up to an  additional  $500 million  based on the prices
realized on production  subsequent to December 31, 1999). 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.  The major  portion of the sale closed on April
26,  2000.  The  remainder  of the assets are  expected to be  transferred  upon
receipt of government approvals.

Merger agreement with Vastar Resources, Inc.

  On May 24, 2000 BP Amoco announced that it had entered into a merger agreement
with Vastar  Resources,  Inc.  (Vastar) which provides for the acquisition by BP
Amoco of  Vastar's  publicly-held  minority  stockholding  at a price of $83 per
share.  The  agreement  is the  outcome  of  negotiations  between  BP Amoco and
Vastar's special  committee which followed BP Amoco's  announcement on March 16,
2000 of its intention to make an offer of $71 per share for the Vastar minority.
The merger has been approved by the Vastar  board,  including all the members of
the special committee.  Through its combination with ARCO, BP Amoco already owns
approximately  81.9 per  cent of  Vastar.  The  acquisition  of the  outstanding
minority  stockholders  under the terms of the merger  agreement would allow the
integration of Vastar with BP Amoco's own operations.

  The  acquisition  is  structured  as  a  merger  of  a  wholly-owned  indirect
subsidiary  of BP Amoco into  Vastar and will not  involve a tender  offer.  The
merger is  contingent  on the approval by the holders of at least  two-thirds of
the Vastar shares not held by BP Amoco at a meeting  scheduled for the summer of
2000.

Unaudited Pro Forma Condensed Consolidated Financial Information

  The following Unaudited Pro Forma Condensed Consolidated Financial Information
gives  pro forma  effect to the  merger,  after  giving  effect to the pro forma
adjustments  described  in the  accompanying  notes.  The  Unaudited  Pro  Forma
Condensed  Consolidated Financial Information has been prepared from, and should
be read in conjunction with, the historical  consolidated  financial  statements
and notes thereto of BP Amoco, which are included in BP Amoco's Annual Report on
Form 20-F for the year  ended  December  31,  1999 (the 1999 Form  20-F) and the
historical  Financial  Statements  of ARCO which are included  elsewhere in this
report on Form 6-K.

  The  Unaudited  Pro Forma  Condensed  Consolidated  Financial  Information  is
provided for  illustrative  purposes only and does not purport to represent what
the actual  results of operations  or the  financial  position of BP Amoco would
have been had the merger of ARCO with a subsidiary  of BP Amoco  occurred on the
respective dates assumed, nor is it necessarily  indicative of BP Amoco's future
operating results or consolidated financial position.

  The Unaudited Pro Forma Condensed  Consolidated Financial Information has been
prepared in accordance with UK generally accepted accounting practice (UK GAAP),
which  differs in certain  respects  from US GAAP.  Note 44 to the  consolidated
financial statements of BP Amoco included in the 1999 Form 20-F, which presented
financial  information  for the years ended  December 31,  1999,  1998 and 1997,
provides a description of the principal  differences between UK GAAP and US GAAP
as they relate to BP Amoco. A reconciliation of the pro forma profit and the pro
forma ordinary shareholders' interest to US GAAP is included in Note 9 of Notes
to the Unaudited Pro Forma Condensed Consolidated Financial Information.

  BP Amoco's  use of the  replacement  cost basis for  inventory  accounting  is
explained in Note 1 of Notes to the Unaudited Pro Forma  Condensed  Consolidated
Financial  Information.  The replacement cost basis is generally  similar to the
LIFO basis.

  BP Amoco will account for the merger as an acquisition  under UK GAAP and as a
purchase under US GAAP. Under UK GAAP acquisition  accounting,  the identifiable
assets and  liabilities  of ARCO are recorded at their fair value on the date of
acquisition.  The date of acquisition for determining the cost of acquisition is
the date on which  control of ARCO passed to BP Amoco,  that is April 13,  2000,
the  date on  which  the FTC  cleared  the  transaction  and  the  offer  became
unconditional.  The cost of  acquisition  comprises  the fair  value of BP Amoco
shares issued together with the expenses of acquisition. The cost of acquisition
and the fair  values  used in the  Unaudited  Pro Forma  Condensed  Consolidated
Financial Information are provisional and may differ from the finally determined
amounts.  UK GAAP  requires  the  identification  and  valuation  of assets  and
liabilities   acquired  to  be   completed  by  the  date  on  which  the  first
post-acquisition financial statements of BP Amoco are approved by the directors.
The relevant financial  statements will be those for the year ended December 31,
2000  approved  by the  directors  in  February  2001.  These fair values may be
amended if  necessary  in the next  financial  statements  with a  corresponding
adjustment  to  goodwill.  BP  Amoco  has  estimated  the  fair  values  of  all
significant  assets and liabilities of ARCO, apart from the restructuring  costs
of approximately  $650 million to be incurred  following the combination as such
costs may not be  recognized  as at the date of  acquisition  under UK GAAP.  BP
Amoco has averaged the closing share price and the  (pound)/$  exchange rate for
the two working  days  between  the offer  becoming  unconditional  and the ARCO
shares being exchanged for BP Amoco shares on April 18, 2000. This average price
of (pound)5.2925, has been translated into US dollars at $1.5857 to (pound)1.00,
the average of the closing rates on those two days.

  Under US GAAP purchase accounting,  the cost of acquisition is based on the BP
Amoco  share  price for a  reasonable  period  before and after the terms of the
acquisition were agreed. BP Amoco has averaged the share price and the (pound)/$
exchange rate for three working days  straddling  the date of the  announcement,
that is,  March 31,  April 1 and April 6, 1999.  The London  Stock  Exchange was
closed  for  the  Easter  holiday  on  April 2 and 5.  This  average  price  was
(pound)5.115,   which  has  been  translated  into  US  dollars  at  $1.6049  to
(pound)1.00, the average closing rate on those three days.

  The historical  financial  statements of ARCO have been prepared in accordance
with US GAAP.  For purposes of  presenting  the  Unaudited  Pro Forma  Condensed
Consolidated Financial  Information,  financial information relating to ARCO has
been adjusted to conform materially with BP Amoco's accounting policies under UK
GAAP as  described  in Note 3 of  Notes to the  Unaudited  Pro  Forma  Condensed
Consolidated Financial  Information.  In the historical financial statements for
ARCO the net  income and net assets of those  operations  and assets  which were
required to be sold as a condition of the agreement of the FTC to the merger are
shown as one amount.

<PAGE>
  The pro forma acquisition  adjustments reflected in the accompanying Unaudited
Pro  Forma  Condensed  Consolidated  Income  Statements  and  Balance  Sheet and
described in Notes 5 and 7,  respectively,  reflect  estimates  made by BP Amoco
management and assumptions  that it believes to be reasonable.  There are no pro
forma adjustments in the accompanying Unaudited Pro Forma Condensed Consolidated
Income  Statements to eliminate  transactions  between ARCO and BP Amoco because
such amounts are considered to be immaterial.  No account has been taken, within
the Unaudited Pro Forma Condensed  Consolidated  Financial  Information,  of any
cost savings or any severance and restructuring  costs which may or are expected
to occur as a result of the combination.

  ARCO  shareholders  were  entitled to  receive,  for each share of ARCO common
stock  held as of the  effective  time of the  merger,  9.84 BP  Amoco  ordinary
shares.  Such BP Amoco  ordinary  shares were  delivered in the form of BP Amoco
ADSs, each of which represents six BP Amoco ordinary shares, or, at the election
of ARCO  shareholders,  BP Amoco ordinary shares.  For purposes of the pro forma
adjustments  within the Unaudited  Pro Forma  Condensed  Consolidated  Financial
Information at March 31, 2000, the number of ARCO shares issued and  outstanding
on April 17, 2000 (324 million  shares)  together with the  estimated  number of
additional  shares  which may be issued in respect of  outstanding  options  and
contingent  stock and on conversion of ARCO preference stock (15 million shares)
have been used, which would result in the issue of  approximately  3,335 million
BP Amoco ordinary shares.

                UNAUDITED PRO FORMA CONDENSED CONSOLIDATED INCOME STATEMENT
                     For the Three Months Ended March 31, 2000

  The following unaudited pro forma condensed  consolidated income statement for
the three months ended March 31, 2000 is derived from the  unaudited  historical
condensed  consolidated  income  statements  of BP Amoco  and ARCO for the three
months then ended, after giving effect to the pro forma adjustments described in
the  Notes  to  the  Unaudited  Pro  Forma  Condensed   Consolidated   Financial
Information.  These  adjustments  have been  determined as if the combination of
ARCO and BP Amoco took place on January 1, 1999,  the first day of the  earliest
financial  period  presented in the Unaudited Pro Forma  Condensed  Consolidated
Financial Information.  The Unaudited Pro Forma Condensed Consolidated Financial
Information has been prepared from, and should be read in conjunction  with, the
historical  consolidated  financial  statements  and notes  thereto of BP Amoco,
which are included in the 1999 Form 20-F and the historical financial statements
of ARCO which are included elsewhere in this report on Form 6-K.

                      For the Year Ended December 31, 1999

  The following unaudited pro forma condensed  consolidated income statement for
the year ended  December  31,  1999 is  derived  from the  historical  condensed
consolidated  income  statements  of BP Amoco and ARCO for the year then  ended,
after giving effect to the pro forma  adjustments  described in the Notes to the
Unaudited  Pro  Forma  Condensed  Consolidated   Financial  Information.   These
adjustments have been determined as if the combination of ARCO and BP Amoco took
place on  January  1,  1999,  the first  day of the  earliest  financial  period
presented in the Pro Forma Condensed  Consolidated  Financial  Information.  The
Unaudited  Pro  Forma  Condensed  Consolidated  Financial  Information  has been
prepared  from,  and  should  be  read  in  conjunction   with,  the  historical
consolidated  financial  statements  and notes  thereto  of BP Amoco,  which are
included in the 1999 Form 20-F and the historical  financial  statements of ARCO
which are included elsewhere in this report on Form 6-K.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                      CONSOLIDATED FINANCIAL INFORMATION

Note 1--Replacement cost profit

  Operating  profit is a UK GAAP  measure of trading  performance.  It  excludes
profits and losses on the sale or  termination  of  operations  and  fundamental
restructuring costs, interest expense and taxation.

  BP Amoco  determines  operating  profit on a  replacement  cost  basis,  which
eliminates the effect of inventory holding gains and losses. For the oil and gas
industry,  the price of crude oil can vary  significantly from period to period,
hence the value of crude oil (and products) also varies.  As a consequence,  the
amount  that  would be  charged  to cost of sales on a FIFO  basis of  inventory
valuation would include the effect of oil price fluctuations on oil and products
inventories.  BP Amoco therefore  charges cost of sales with the average cost of
supplies  incurred during the period rather than the historical cost of supplies
on a FIFO basis.  For this purpose,  inventories at the beginning and end of the
period are valued at the  average  cost of supplies  incurred  during the period
rather than at their  historical  cost.  These  valuations are made quarterly by
each business unit,  based on local oil and product price indices  applicable to
their  specific  inventory  holdings,  following  a  methodology  that  has been
consistently  applied  by BP  Amoco  for many  years.  Operating  profit  on the
replacement  cost basis is used by BP Amoco management as the primary measure of
business unit trading  performance,  and BP Amoco management  believes that this
measure assists investors to assess the group's underlying  trading  performance
from period to period.

  Replacement  cost is not a US GAAP measure.  The major US oil companies  apply
the LIFO basis of inventory valuation.  The LIFO basis is not permitted under UK
GAAP. The LIFO basis  eliminates the effect of price  fluctuations  on crude oil
and product inventory except where an inventory  drawdown occurs in a period. BP
Amoco  management  believes that,  where  inventory  volumes remain  constant or
increase  in a  period,  operating  profit  on the LIFO  basis  will not  differ
materially from operating profit on BP Amoco's replacement cost basis.

  Where an inventory drawdown occurs in a period,  cost of sales on a LIFO basis
will be charged with the historical cost of the inventory drawn down, whereas BP
Amoco's  replacement  cost basis  charges  cost of sales at the average  cost of
supplies  for the  period.  To the extent that the  historical  cost on the LIFO
basis of the inventory  drawn down is lower than the current cost of supplies in
the period,  operating  profit on the LIFO basis will be greater than  operating
profit on BP Amoco's  replacement  cost basis. To the extent that the historical
cost on the LIFO basis of the  inventory  drawn down is greater than the current
cost of supplies in the period, operating profit on the LIFO basis will be lower
than operating profit on BP Amoco's replacement cost basis.

  Replacement cost profit before  exceptional  items excludes profits and losses
on the sale or termination of operations and  fundamental  restructuring  costs,
which are defined by UK GAAP. This is the measure of profit used by the BP Amoco
board of directors in setting targets for and monitoring  performance  within BP
Amoco. BP Amoco's management  believes this indicator provides the most relevant
and useful measure for investors because it most accurately  reflects underlying
trading performance.

Note 2--Reclassification

  Reclassifications  have been made to the ARCO historical financial information
presented under US GAAP to conform to BP Amoco's presentation under UK GAAP.

Note 3--Significant differences between ARCO's accounting policies under US GAAP
and BP Amoco's accounting policies under UK GAAP

  ARCO  prepares  its  financial  statements  in  accordance  with US GAAP.  For
purposes of preparing  the  Unaudited Pro Forma  Condensed  Consolidated  Income
Statements  and  Balance  Sheet,  the  financial  statements  of ARCO  have been
restated to conform with BP Amoco  accounting  policies  under UK GAAP by giving
effect to the adjustments described below.

                 CONSOLIDATED FINANCIAL INFORMATION (Continued)

Note 3--Significant differences between ARCO's accounting policies under US GAAP
and BP Amoco's accounting policies under UK GAAP (continued)

Consolidation basis

  Under US GAAP, ARCO's interest in a cogeneration  facility is  proportionately
consolidated, whereas under UK GAAP the joint venture would be equity accounted.

Inventory accounting

  ARCO carries inventories at the lower of current market value or cost. Cost is
determined  under the LIFO method for the majority of  inventories  of crude oil
and  petroleum  products.  The costs of  remaining  inventories  are  determined
predominantly on an average cost basis.

  BP Amoco carries  inventories  at the lower of cost or net  realizable  value.
Cost to BP Amoco is determined  using the FIFO method.  Cost of sales determined
on a FIFO basis is adjusted to a  replacement  cost basis,  i.e., to reflect the
average cost of supplies  incurred  during the period,  by  excluding  inventory
holding gains and losses.

Deferred taxation

  Under the UK GAAP  restricted  liability  method,  deferred  taxation  is only
provided for where timing differences are expected to reverse in the foreseeable
future.  For US GAAP under the liability  method,  deferred taxation is provided
for  temporary  differences  between the financial  reporting  basis and the tax
basis of assets and liabilities at enacted tax rates.

Exceptional items

  Under UK GAAP,  certain  exceptional items are shown separately on the face of
the income statement after operating  profit.  These items are profits or losses
on  the  sale  or  closure  of  businesses  and  fixed  assets  and  fundamental
restructuring  charges.  Under US GAAP,  these items other than for discontinued
operations are classified as operating income or expenses.

Equity accounting

  UK GAAP requires the investor's share of operating profit or loss, exceptional
items,  interest  expense and  taxation  of  associated  undertakings  and joint
ventures  to be shown  separately  from  those of the  group.  For US GAAP,  the
after-tax profits or losses (i.e.  operating  results after  exceptional  items,
interest  expense and taxation) are included in the income statement as a single
line item.

  UK  GAAP  requires  the  investor's  share  of  the  gross  assets  and  gross
liabilities  of joint  ventures  to be shown on the face of the  balance  sheet,
whereas under US GAAP the net investment is included as a single line item.

Provisions

  UK GAAP requires provisions for decommissioning and environmental  liabilities
to be determined on a discounted  basis if the effect of the time value of money
is material.

  Provisions for  decommissioning are recognized in full, on a discounted basis,
at the commencement of oil and natural gas production. UK GAAP also requires the
capitalization  as a tangible  fixed  asset and  subsequent  depreciation  of an
amount equivalent to the provision.

  The unwinding of the discount,  which represents a  period-by-period  cost, is
included within interest expense.  Under US GAAP (i)  environmental  liabilities
are  discounted  only  where the timing and  amounts of  payments  are fixed and
reliably  determinable and (ii) provisions for  decommissioning are provided for
on a unit-of-production basis over field lives.

Note 3--Significant differences between ARCO's accounting policies under US GAAP
and BP Amoco's accounting policies under UK GAAP (continued)

Impairment

  Both UK and US GAAP require that  long-lived  assets and certain  identifiable
intangibles to be held and used by an entity be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable.

  US GAAP requires,  in performing the review for recoverability,  the entity to
estimate the future cash flows  expected to result from the use of the asset and
its  eventual  disposition.  If the  sum  of  the  expected  future  cash  flows
(undiscounted  and without interest charges) is less than the carrying amount of
the asset,  an impairment  loss is recognized,  otherwise no impairment  loss is
recognized.  Measurement  of  an  impairment  loss  for  long-lived  assets  and
identifiable  intangibles that an entity expects to hold and use is based on the
fair value of the assets.

  For UK GAAP, to the extent that the carrying  amount  exceeds the  recoverable
amount, that is the higher of net realizable value and value in use (fair value)
the fixed asset is written down to its recoverable amount.

  The loss on sale of  businesses  recognised  for US GAAP in ARCO's  historical
financial  statements  in 1999 has been  treated as a fair value  adjustment  at
January 1, 1999 for UK GAAP.

Business combinations

  US GAAP requires the  recognition of a deferred tax asset or liability for the
tax  effects of  differences  between the  assigned  values and the tax bases of
assets  acquired and  liabilities  assumed in a purchase  business  combination,
whereas  under UK GAAP no such  deferred tax asset or  liability is  recognized.
Under US GAAP the deferred  tax asset or  liability  is amortized  over the same
period as the assets and liabilities to which it relates.

  US GAAP requires certain  reorganization  and integration costs to be incurred
as part of a purchase  business  combination  to be  recognized  as  liabilities
assumed and included in the allocation of the acquisition cost. UK GAAP does not
generally  permit  recognition  of these costs as part of the accounting for the
business combination.

Investments

  Under US GAAP ARCO has  classified  its  investments  in  LUKOIL  ADRs and the
Zhenhai Refining and Chemical Company  convertible  bonds as available for sale.
Consequently they are reported at fair value, with unrealized  holding gains and
losses,  net of tax,  reported in accumulated other  comprehensive  income. If a
decline in fair value below cost is "other than  temporary" the unrealized  loss
should be accounted for as a realized loss and charged against income.  Under UK
GAAP these  investments  are deemed to be long term and  carried in the  balance
sheet at cost, subject to review for impairment.

Pensions

  US GAAP  requires an additional  minimum  liability to be shown in the balance
sheet if the accumulated  benefit  obligation  exceeds the fair value of pension
plan  assets.  UK GAAP does not  require  recognition  of a  liability  in these
circumstances.

Debt

  For US  GAAP  borrowings  under  US  Industrial  Revenue/Municipal  Bonds  are
classified as non-current liabilities.

  For UK GAAP such  borrowings are classed as current  liabilities - falling due
within one year.

Note 5--Pro Forma adjustments to the consolidated income statements

  The Unaudited Pro Forma Condensed  Consolidated  Income Statements give effect
to the pro forma adjustments set out below.

(a)   The depreciation and amortization  rates for the fair value adjustments to
      tangible fixed assets and goodwill are set out below.

      Depreciation: Exploration and Production assets have been depreciated on a
      unit-of-production   basis.   Refining  and  Marketing  assets  have  been
      depreciated over 15 years (refineries) and 10 years (marketing assets).

      Goodwill: Amortized over a period of 10 years.

(b)   The  difference  between  the fair  value and the  carrying  value of ARCO
      long-term  debt,  including  current  maturities,  ($229 million) has been
      amortized on a constant  yield basis over the  remaining  term of the debt
      and is shown as an adjustment to interest expense.

(c)   Minority shareholders' interest

      This represents the share of the other pro forma adjustments  attributable
      to minority shareholders.

(d)   Dividend requirements on preference shares

      It has been  assumed that ARCO  preference  shares were  exchanged  for BP
      Amoco ordinary shares on completion of the merger.

  All the adjustments  apart from (d) above will have a continuing  effect.  The
estimated charge for additional depreciation and amortization of goodwill in the
first full year following the combination is $2.0 billion.

Note 7--Pro Forma adjustments to the consolidated balance sheet

  The Unaudited Pro Forma Condensed  Consolidated  Balance Sheet gives effect to
the pro forma adjustments set forth below, which include  adjustments to reflect
the fair  values of the assets  and  liabilities  of ARCO under the  acquisition
method of accounting.

  BP Amoco expects to incur severance and other  restructuring costs as a result
of the  combination.  Preliminary  estimates  indicate  that these costs will be
approximately  $700 million;  $50 million have been  reflected in the fair value
adjustment  and the remaining $650 million will be charged to income as and when
the  criteria  for  recognition  of  such  costs  under  UK GAAP  are  met  and,
accordingly,  no amount for these costs has been  included in the  Unaudited Pro
Forma Condensed Consolidated Financial Information.  For US GAAP $450 million of
these  costs have been  included as part of the fair value  adjustments  and the
remaining  $250  million  will be  charged  to  income  when  the  criteria  for
recognition under US GAAP have been met.

  The Unaudited Pro Forma Condensed  Consolidated Balance Sheet does not include
adjustments to eliminate  amounts  payable and  receivable  between BP Amoco and
ARCO, because such amounts are not considered material.

Fair value adjustments

  The methods and assumptions  set out in the following  paragraphs were used in
estimating the preliminary fair value of the assets and liabilities acquired.

  Tangible and intangible fixed assets

  The fair value of the tangible and  intangible  assets have been  estimated by
determining  the net  present  value of future  cash flows.  The  increase  over
carrying  value for tangible  fixed assets was $7,490 million and for intangible
fixed  assets was $3,788  million.  The fair  value of fixed  asset  investments
exceeds their carrying value by $773 million.

  Goodwill  represents the difference  between the value of the business and the
value of the assets acquired. The goodwill created was $6,808 million.

  Net assets of operations sold as required by the FTC

  The fair value of the net assets of these  operations  reflects the  estimated
sales proceeds, net of attributable taxation.

  Inventories

  Inventories has been revalued on a replacement cost basis.

  Finance debt

  The fair value of ARCO long-term debt, including current maturities,  has been
estimated based on the quoted market prices for the same or similar issues.  The
adjustment  increases the book value of finance debt by $229 million. As part of
the fair  value  exercise  finance  lease  obligations  were  increased  by $136
million.

  Other provisions

  Liabilities  for  pensions  and  other  post  retirement  benefits  have  been
estimated by independent  actuaries.  Provisions for other liabilities have been
reassessed in line with BP Amoco practice.

  Other assets and liabilities

  The carrying amounts for most other assets and liabilities  approximate  their
fair value.

  Minority shareholders' interest

  A part of the fair value  adjustment  relating  to Vastar  Resources,  Inc. is
ascribed to the minority shareholders' interest.

Consideration

  ARCO  shareholders  received  for each share of ARCO  common  stock held as of
April 17, 2000,  9.84 BP Amoco ordinary  shares.  Such BP Amoco ordinary  shares
were  delivered  in the form of BP Amoco ADSs or, at the election of a holder of
ARCO common  stock,  BP Amoco  ordinary  shares.  For  purposes of the pro forma
adjustments  within the Unaudited  Pro Forma  Condensed  Consolidated  Financial
Information at March 31, 2000, the number of ARCO shares issued and  outstanding
on April 17, 2000 (324 million  shares)  together with the  estimated  number of
additional  shares  which may be issued in respect of  outstanding  options  and
contingent  stock and on conversion of ARCO preference stock (15 million shares)
have been used, which would result in the issue of  approximately  3,335 million
BP Amoco ordinary shares or 556 million BP Amoco ADSs.

  For the purposes of the Unaudited Pro Forma Condensed  Consolidated  Financial
Information, the cost of acquisition has been determined as follows:

Accruals for amounts and payable on the combination

  Stamp Duty  Reserve  Tax (SDRT) of 1.5% of the value of the BP Amoco  ordinary
shares  underlying the BP Amoco ADSs, at the time the BP Amoco  ordinary  shares
are  transferred to the  depositary (or its nominee),  is payable by BP Amoco on
the issue of BP Amoco ADSs. To the extent that ARCO shareholders elected to take
BP Amoco  ordinary  shares  (which  underlie BP Amoco ADSs) rather than ADSs, BP
Amoco had no SDRT liability for the ordinary  shares issued.  The amount of SDRT
payable has been estimated at $315 million.

  The  estimated  amounts of SDRT ($315  million) and BP Amoco and ARCO fees and
expenses ($140 million and $68 million  respectively)  payable have been accrued
for the  purposes of these  adjustments.  SDRT is a share issue  expense and has
been charged against the paid-in surplus.

Combination adjustments

  The combination  adjustments  eliminate the ARCO common stock, ARCO preference
shares, paid-in surplus and retained earnings and recognize the goodwill arising
on acquisition.

Change in basis of accounting

  Both BP Amoco and ARCO held  interests in Great  Yarmouth  Power Limited which
were  equity  accounted  prior to the  acquisition.  Following  the  merger  the
combined interests have been consolidated.

Note 8--Operating cost savings

  BP Amoco  expects  to  achieve  an annual  rate of  pre-tax  cost  savings  of
approximately  $1  billion  during  the second  full year of  operations  of the
combined  enterprise,   through   organizational   efficiencies,   more  focused
exploration  efforts,  standardization  and simplification of business processes
and  rationalization  of  operations.  No  adjustment  has been  included in the
Unaudited  Pro  Forma  Condensed  Consolidated  Financial  Information  for  the
anticipated benefits of these operating cost savings.  There can be no assurance
that anticipated cost savings will be achieved in the expected amounts or at the
times anticipated.

Note 9--Significant differences between UK GAAP and US GAAP

  The Unaudited Pro Forma Condensed  Consolidated Financial Information has been
prepared in accordance with UK GAAP,  which differs in certain  respects from US
GAAP.

  The main  differences  between  UK GAAP and US GAAP  that are  relevant  to BP
Amoco's Unaudited Pro Forma Condensed Consolidated Financial Information are set
out below.

  For US GAAP the cost of acquisition has been determined as follows:

Group consolidation

  Investments  in  entities  over  which the  Group  does not  exercise  control
(associates and joint ventures) are accounted for by the equity method.

  UK GAAP requires the consolidated  financial statements to show separately the
Group  proportion  of operating  profit or loss,  exceptional  items,  inventory
holding   gains  or  losses,   interest   expense  and  taxation  of  associated
undertakings  and joint  ventures.  In addition the  turnover of joint  ventures
should be disclosed. For US GAAP the after tax profits or losses (i.e. operating
results after exceptional  items,  inventory  holding gains or losses,  interest
expense and  taxation)  are  included in the income  statement  as a single line
item.

  UK GAAP requires the Group's  share of the gross assets and gross  liabilities
of joint  ventures to be shown on the face of the balance sheet whereas under US
GAAP the net investment is included as a single line item.

  Where the Group conducts  activities  through a joint  arrangement that is not
carrying on a trade or business in its own right the Group  accounts for its own
assets,  liabilities  and cash flows of the activity  measured  according to the
terms of the  arrangement.  For the Group this method of  accounting  applies to
certain oil and natural gas activities and undivided interests in pipelines.  US
GAAP allows these activities to be accounted for by proportional  consolidation,
which is equivalent to UK GAAP.

Note 9--Significant differences between UK GAAP and US GAAP (Continued)

Income statement

  The income  statement  prepared under UK GAAP shows sub-totals for replacement
cost profit before interest and tax,  historical cost profit before interest and
tax and profit  after  taxation.  These line items are not  recognized  under US
GAAP.

Exceptional items

  Under UK GAAP certain  exceptional  items are shown  separately on the face of
the income statement after operating  profit.  These items are profits or losses
on the  sale of  businesses  and  fixed  assets  and  fundamental  restructuring
charges.  Under US GAAP  these  items  are  classified  as  operating  income or
expenses.

Impairment

  Both UK and US GAAP require that  long-lived  assets and certain  identifiable
intangibles to be held and used by an entity be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may  not be  recoverable.  US  GAAP  requires,  in  performing  the  review  for
recoverability,  the entity to estimate the future cash flows expected to result
from  the use of the  asset  and  its  eventual  disposition.  If the sum of the
expected future cash flows  (undiscounted  and without interest charges) is less
than the  carrying  amount  of the  asset,  an  impairment  loss is  recognized.
Otherwise,  no impairment loss is recognized.  Measurement of an impairment loss
for long-lived  assets and  identifiable  intangibles  that an entity expects to
hold and use is based on the fair value of the assets.

  For UK GAAP to the extent that the  carrying  amount  exceeds the  recoverable
amount, that is the higher of net realizable value and value in use (fair value)
the fixed asset is written down to its recoverable amount.

Provisions

  UK GAAP  requires  that the  amount  recognised  as a  provision  should be an
estimate of the  expenditure  required to settle the  obligation  at the balance
sheet  date.  Provisions  for  decommissioning,  environmental  liabilities  and
onerous  contracts  should be determined on a discounted  basis if the effect of
the time value of money is material.

  Under US GAAP if the  probable  cost of settling  the  obligation  is within a
range of estimated  amounts and no amount  within the range appears to be a more
likely  outcome  than any other amount in the range,  the minimum  amount in the
range should be accrued.  Also under US GAAP (i)  environmental  liabilities are
discounted  only where the timing and amounts of payments are fixed and reliably
determinable  and  (ii)  provisions  for   decommissioning  are  provided  on  a
unit-of-production basis over field lives.

Deferred taxation

  Under the UK GAAP  restricted  liability  method,  deferred  taxation  is only
provided  where timing  differences  are expected to reverse in the  foreseeable
future.  Under US GAAP deferred  taxation is provided for temporary  differences
between the financial  reporting  basis and the tax basis of the Group's  assets
and liabilities at enacted tax rates.

  US GAAP requires the  recognition of a deferred tax asset or liability for the
tax  effects of  differences  between the  assigned  values and the tax bases of
assets  acquired and  liabilities  assumed in a purchase  business  combination,
whereas  under US GAAP no such  deferred tax asset or  liability is  recognized.
Under US GAAP the deferred  tax asset or  liability  is amortized  over the same
period as the assets and liabilities to which it relates.

  The adjustments  for fixed assets,  depreciation  and deferred  taxation arise
from the difference between the UK GAAP and US GAAP bases for deferred taxation.

Note 9--Significant differences between UK GAAP and US GAAP (Continued)

Ordinary shares held for future awards to employees

  Under UK GAAP, Company shares held by an Employee Share Ownership Plan to meet
future  requirements of employee share schemes are recorded in the balance sheet
as Fixed assets --  investments.  Under US GAAP, such shares are recorded in the
balance sheet as a reduction of shareholders' interest.

Sale and leaseback

  The sale and leaseback of the Amoco  building in Chicago,  Illinois in 1998 is
treated as a sale for UK GAAP  whereas  for US GAAP it is treated as a financing
transaction.

  A provision was recognized under UK GAAP in 1999 to cover the likely shortfall
on rental income from  subletting the Chicago office  building.  As the original
sale and  leaseback was not treated as a sale for US GAAP the provision has been
reversed for US GAAP.

  Under UK GAAP the  profit  arising  on the sale  and  operating  leaseback  of
certain  railcars  in 1999 is  taken  to  income  in the  period  in  which  the
transaction occurs. Under US GAAP this profit is not recognized  immediately but
amortized over the term of the operating lease.

Dividends

  Under UK GAAP, dividends are recorded in the year in respect of which they are
announced or declared by the board of directors  to the  shareholders.  Under US
GAAP, dividends are recorded in the period in which dividends are declared.

            2(a) FINANCIAL INFORMATION OF ATLANTIC RICHFIELD COMPANY

                        INDEPENDENT ACCOUNTANTS' REPORT

To the Board of Directors and Shareholders
of Atlantic Richfield Company

  In  our  opinion,   the  consolidated   financial  statements  listed  in  the
accompanying  index appearing on pages 30, 34, 35 and 40 present fairly,  in all
material respects,  the financial position of Atlantic Richfield Company and its
subsidiaries at December 31, 1999 and 1998, and the results of their  operations
and their cash flows for each of the three  years in the period  ended  December
31, 1999, in conformity with  accounting  principles  generally  accepted in the
United States. In addition,  in our opinion,  the financial  statement  schedule
listed in the accompanying  index appearing on page 98 presents  fairly,  in all
material  respects,  the  information set forth therein when read in conjunction
with the related consolidated  financial statements.  These financial statements
and  financial  statement  schedule  are  the  responsibility  of the  Company's
management;  our  responsibility  is to express  an  opinion on these  financial
statements and financial  statement  schedule based on our audits.  We conducted
our audits of these statements in accordance with auditing  standards  generally
accepted in the United  States which  require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and  disclosures in the financial  statements,  assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion expressed above.

Operating Review

                                 Introduction

  In 1999, ARCO took a number of actions,  primarily divestitures,  to implement
its  strategy  of  focusing  on key  oil and gas  businesses.  The  divestitures
included both non-oil and gas businesses and non-core oil and gas properties. In
addition,   ARCO  achieved  total   before-tax  cost  reductions  in  operating,
exploration,  and selling,  general, and administrative  (SG&A) expenses of over
$740 million,  compared to baseline 1998 expenses.  This achievement in one year
exceeded the two-year goal of $500 million  announced in October 1998. All areas
of ARCO's business  contributed to the cost reductions,  which were increased by
expense  timing  factors.  Adjusted  for these  items,  ARCO  believes  that the
sustainable annual savings are on the order of $650 million.  However, the event
which could have the greatest  potential  impact on the company in the future is
the proposed combination of BP Amoco and ARCO. The combination has been approved
by the shareholders of both ARCO and BP Amoco. The European  Commission approved
the  transaction  with some  stipulations  on September 29, 1999. On February 4,
2000, the Federal Trade  Commission (FTC) filed a complaint in the United States
District Court in San Francisco alleging that the combination violated section 7
of the Clayton Act and filed a motion for  preliminary  injunction  to enjoin BP
Amoco  from  completing  the  combination.  The  status  of the  combination  is
discussed in detail on page 1.

  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 1999 and 1998.  Discontinued  operations,  unallocated expenses, and other
operations,  which include Lower 48 pipelines and aluminum,  are also  examined.
The  consolidated  results of these  operations  are examined in relation to the
Consolidated Statement of Income on page 30.

  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.  In  addition,  as a result of the  company's  cost  reduction  program,
combined  operating,  exploration,  and 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.

  During  1999,  ARCO's  total  production  grew  to  1,019,600  barrels  of oil
equivalent per day (BOEPD), primarily due to increased international production,
which grew to 345,500 BOEPD.

  ARCO's 1998 exploration and production  operating  results were  significantly
impacted by lower crude oil prices and, to a lesser extent,  higher  exploration
expenses.  The impact of lower  natural  gas prices  was  essentially  offset by
increased  natural gas production.  The former Union Texas  Petroleum  Holdings,
Inc. (UTP)

                         Results of Segment Operations

  Properties  obtained  through  the  purchase  of UTP at the end of the  second
quarter of 1998 contributed to a 4% increase in production volumes for the year.
The  added  revenues  from  that   production  were  more  than  offset  by  the
depreciation,  depletion,  and amortization (DD&A), which included the allocated
purchase price, and the operating costs associated with those properties.

  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.  See page 32 of the "Results of  Consolidated  Operations" for a
further discussion of the 1998 impairment.  Special items also included aftertax
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.

</TABLE>
  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
barrels per day (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  sold 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 increased  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.

  In 1998, increased petroleum liquids production primarily reflected 36,700 BPD
contributed  by the former UTP  properties,  partially  offset by natural  field
decline in Alaskan fields.

  ARCO has begun development of the Alpine field and other satellite discoveries
which will help stabilize production in Alaska after 1999.

  In 1999,  the growth in  international  natural gas  production  reflected the
impact of a full year of production contributed by former UTP properties in 1999
versus only six months of production in 1998,  along with  increased  production
from the United Kingdom North Sea. 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.

  The 1998 growth in international  natural gas production  primarily  reflected
167 million cubic feet per day (MMCFD)  contributed  from former UTP properties,
partially  offset by declines of  approximately  80 MMCFD associated with ARCO's
other  properties,  including  a 53  MMCFD  decline  from  Indonesia.  In  1998,
Indonesian  volumes fell due to the severe effect of the Asian financial  crisis
on Indonesia's economy.

</TABLE>
  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.  Gasoline sales volumes increased 2%
at existing ARCO retail outlets.

  In 1998,  light  product  margins were lower  resulting  in reduced  operating
results.  Jet fuel imports from Asia into the West Coast  marketing  area led to
changes in product mix for refineries on the West Coast.  This change  increased
the supply of gasoline  and diesel,  causing  margins to decline as gasoline and
diesel prices fell more than crude oil prices during the year.

  The 1999 and 1998 net income included a benefit of  approximately  $44 million
and $17 million after tax, respectively, associated with the amortization of the
deferred  pre-tax  gain on the sale of ARCO's  chemical  interest.  See "Gain on
Disposition of Discontinued Operations" on page 28.

  In 1998,  a special  items  charge of $13  million  for  personnel  reductions
associated  with ARCO's cost  reduction  programs was offset by favorable  legal
settlements.  The 1997  special  items  charge  primarily  related to  personnel
reductions associated with cost reduction programs.

Margins on the sale of purchased  products are lower than on products  produced.
The  decreased  jet fuel sales in 1999 and 1998,  compared to 1997,  reflected a
change in the production mix and  turnarounds at ARCO's Cherry Point Refinery in
both 1999 and 1998.

  Results from ARCO's other operations  comprise earnings from Lower 48 pipeline
operations and an aluminum  rolling  facility.  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.  The  increase in 1998  earnings,
compared to 1997, primarily reflected improved operating results from the Seaway
pipeline joint venture.

  Operating  results from the aluminum  operations  were relatively flat for the
three years ended December 31, 1999.

  After-tax  charges for environmental  remediation and  restructuring  were $24
million  and $8 million  in 1999,  compared  to $143  million  and $48  million,
respectively,  in 1998. This decrease, 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  shortterm
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.

  In 1997,  unallocated net expense  primarily  included charges of $179 million
after tax for future environmental  remediation and reclamation,  charges of $11
million after tax for  restructurings,  tax benefits  related to affiliate stock
transactions, corporate staff and general expenses and interest revenue.

  The environmental  charges in 1998 and 1997 related both to current operations
and natural resource damage  liabilities in the state of Montana associated with
previously  discontinued  mining  operations.   In  1997,  ARCO  adopted  a  new
environmental   accounting  standard  and  accrued  the  company's  estimate  of
post-remediation monitoring costs.

  After-tax  interest  expense has declined over the last two years after taking
into account the effect of certain  interest  credits in 1998 and 1997. In 1998,
interest  expense  included  interest on a tax refund of $94 million  after tax,
whereas  1997  included  reversal of reserves  for  tax-related  interest of $89
million after tax. The decrease is due primarily to higher capitalized  interest
in 1999 and 1998.  The impact of  increased  interest  capitalization  more than
offset the increase in combined  short and  long-term  debt  outstanding  during
1999.

Extraordinary Loss on Extinguishment of Debt

  The company  incurred a loss of $192 million before tax, or $118 million after
tax, on early  retirement of long-term debt during 1997.  The early  retirements
resulted  in a pre-tax  reduction  in  interest  expense  on  long-term  debt of
approximately $100 million in 1998.

Gain on Disposition of Discontinued Operations

ARCO Chemical

  In July 1998,  ARCO sold its entire  interest  in ARCO  Chemical  to  Lyondell
Chemical  Company  (Lyondell),  an unrelated third party  following  ARCO's 1997
disposition of Lyondell stock, 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 $1.1 billion.

  In  1999,  adjustments  for  tax  benefits  resulted  in the  recording  of an
additional after-tax gain on disposition of $59 million.

  Previously,  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  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.

                         Results of Segment Operations

  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  $44
million and $17 million  after tax on earnings  of the  refining  and  marketing
segment in 1999 and 1998, respectively.

Coal

  In the first quarter of 1999,  ARCO sold its interests in two Australian  coal
mines.  ARCO sold its 80%  interest in the  Gordonstone  coal mine and its 31.4%
interest in the Blair Athol Joint Venture.  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 the  interests in the  Australian  mines 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.

UTP Petrochemical

  At the time of the UTP  acquisition,  ARCO  determined  the UTP  petrochemical
operations  would be divested as soon as  possible.  Accordingly,  in 1998,  $33
million  after  tax  was  accrued  as the  estimated  loss  on  disposal  of the
petrochemical  assets. In March 1999, ARCO sold the UTP  petrochemical  business
and recorded an additional loss of $4 million.

Lyondell

  In September 1997, all of ARCO's 9% Exchangeable Notes due September 15, 1997,
with an  outstanding  principal  amount  of $988  million,  were  redeemed  with
Lyondell  common  stock  owned by ARCO.  ARCO then sold its  remaining  Lyondell
shares in a privately negotiated transaction.  ARCO realized an aggregate pretax
gain of $633 million, or $291 million after tax, on the two transactions.

                      Results of Consolidated Operations

Income from Continuing Operations

  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.

  ARCO's 1998 operating  results were down primarily  because of lower crude oil
prices  along  with  higher  exploration  expenses.  The lower  crude oil prices
reduced operating income by nearly $800 million.

Revenues

  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.

  The decline in exploration and production  revenues in 1998 resulted primarily
from  lower  petroleum  liquids  prices  and  natural  gas  marketing  activity.
Effective  September  1997,  Vastar  contributed  certain  of  its  natural  gas
marketing  operations to a joint venture with  Southern  Energy,  Inc. The joint
venture is accounted  for on the equity  method.  As a result of the transfer of
those operations, the natural gas marketing sales and purchases volumes for 1999
and 1998 were significantly lower compared to 1997.

</TABLE>
  In 1999,  refining and marketing  revenue  primarily  increased as a result of
higher refined products prices.

  The decline in refining and  marketing  sales  revenues in 1998  resulted from
lower refined products prices, only partially offset by increased gasoline sales
volumes.

Other Revenues

  In 1999,  higher other revenues,  compared to 1998,  reflected  one-time legal
settlements and increased interest and rental income.

  In 1998,  other revenues  increased  primarily as a result of improved  equity
earnings from ARCO's pipeline operations and gains from pipeline asset sales.

Expenses

  Trade  purchases  for 1999 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.

  In 1998, trade  purchases,  compared to 1997, were lower primarily as a result
of lower crude oil prices and the  transfer of  Vastar's  natural gas  marketing
operations to the Vastar-Southern Energy, Inc. joint venture.

  Operating  expenses  declined in 1999 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.
<PAGE>

                      Results of Consolidated Operations

  In 1998, operating expenses increased because of added expenses from UTP and a
$91 million provision associated with the exchange of California heavy crude oil
properties.   Charges  for  future  environmental  remediation  and  reclamation
declined to $234 million  before tax. In 1998,  natural gas  marketing  delivery
charges  declined  following the transfer of  operations to the  Vastar-Southern
Energy, Inc. joint venture.

  In 1997,  operating  expenses  included charges of $300 million before tax for
future  environmental  remediation and  reclamation as well as costs  associated
with increased  production from Rhourde El Baguel in Algeria and other new field
production.

  The environmental  charges in 1998 and 1997 related both to current operations
and to natural  resource damage  liabilities in the state of Montana  associated
with previously  discontinued  mining  operations.  In 1997,  these charges also
related to the adoption of a new environmental accounting standard.

  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 1999,  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.

  The higher DD&A expense in 1998  reflected the inclusion of the DD&A of former
UTP operations in the third and fourth quarters of 1998.

  Each year ARCO  performs an impairment  review of its oil and gas  properties.
The 1999 impairment  review resulted in  insignificant  charges related to a few
isolated properties.  ARCO used a benchmark price of $25.60/bbl in preparing its
December 31, 1999 Supplemental Oil and Gas Information.

  In the fourth quarter of 1998, after a year-long  decline in crude oil prices,
ARCO  determined  that part of the oil price  decline  that had taken  place was
permanent.  Accordingly, ARCO revised its official crude oil price forecast used
for economic  decision  making during the fourth quarter of 1998.  This forecast
was based on a West Texas  Intermediate  (WTI) benchmark price of $15 per barrel
(bbl) in 1999,  $16/bbl  in  2000,  and  $17/bbl  in  2001,  with 2%  escalation
thereafter.  While crude oil prices  reached as low as $12/bbl in December 1998,
many oil industry expert forecasts  considered crude oil prices in that range to
be unusually low and  inappropriate  for economic  decision making.  ARCO used a
benchmark  price of $12.05/bbl  in preparing its December 31, 1998  Supplemental
Oil and

Gas Information.

  In accordance with Statement of Financial Accounting Standards (SFAS) No. 121,
in 1998 ARCO performed an impairment  review to determine  whether any of ARCO's
oil and gas properties  were impaired based on the new crude oil price forecast.
Net  undiscounted  cash flows before tax were calculated and compared to the net
book value on a  field-by-field  basis.  This  included  cash flows from  proved
developed, proved undeveloped and potential oil and gas reserves, which included
both  producing  and  non-producing   reserves.   The  potential  reserves  were
calculated on a risk-weighted basis to include the uncertainties associated with
field size,  reservoir  performance,  technological  development  and commercial
risk.  Where  appropriate,  contracted  prices were used but did not  materially
impact the result.  For those fields  where the net book value  exceeded the net
undiscounted  cash flows before tax, the discounted future cash flows before tax
were  calculated  using a 10% discount  rate factor.  This resulted in a pre-tax
impairment  charge of $1.4  billion in 1998.  ARCO also  tested a downside  case
using WTI  benchmark  crude oil  prices  of $1/bbl  lower  than each year of its
official  forecast.  ARCO believes that prices below $14/bbl are not sustainable
and like most  commodities  will cycle around their  historical  midpoints.  The
impaired  properties  included former UTP properties in Pakistan,  Venezuela 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

  Significant  downward  revisions of these oil and gas reserves could result in
material  impairment  provisions in future years if crude oil prices permanently
decline  below the  price  forecast  used in  determining  the 1998  impairment.
Accounting  rules do not permit the reversal of prior  impairments if oil prices
rise.

  The lower  exploration  expense in 1999  reflected a decline in geological and
geophysical and dry-hole expense in ARCO's international  exploration operations
and a decline in Vastar's dry-hole expense.

  In  1998,  ARCO's  international  exploration  operations  incurred  increased
geological  and  geophysical  expense  and  dry-hole  costs.  Vastar  had higher
exploration  expenses of $35 million in 1998 primarily  resulting from increased
dryhole expense associated with deepwater drilling activity.

  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.

  Taxes other than income taxes decreased in 1998 primarily as the result of the
impact of lower crude oil prices and, to a lesser extent,  lower volumes on U.S.
production taxes.

  The 1999  interest  expense  was  slightly  lower,  compared  to  1998,  after
adjusting  the 1998 interest  expense for interest on a tax refund.  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  decrease  in  interest  expense  in 1998  primarily  reflected  increased
capitalized interest compared to 1997.

  In  1998,  $229  million  of the  restructuring  charges  related  to costs of
eliminating approximately 1,200 positions specifically identified as of December
31,  1998.  The $20  million  of  restructuring  charges  in 1999  relates to an
adjustment of the 1998 accrual,  primarily due to the  elimination of additional
positions. The entire 1997 charge was for personnel-related costs. See Note 7 of
Notes to Consolidated  Financial  Statements on page 49 regarding  restructuring
costs.

Income Taxes

  The company had an effective  tax rate of 27.8% in 1999. An effective tax rate
lower than the statutory rate primarily  reflected various tax credits and other
benefits,  partially  offset by taxes on foreign  income in excess of  statutory
rate.  The company had a tax benefit in 1998  reflecting the company's loss from
continuing operations in that year.

  ARCO's 2000 capital  spending  program  includes $2.6 billion for additions to
fixed  assets,  compared to $2.7 billion in 1999.  Future  capital  expenditures
remain subject to business conditions affecting the industry, as well as changes
in  environmental  rules and regulations and the tax laws. They are also subject
to change based on the timing and the status of the combination with BP Amoco.

  Cash and cash equivalents and short-term  investments  totaled $1.1 billion at
year-end 1999,  short-term  borrowings  were $1.7 billion and long-term debt due
within one year was $11 million.

  Beginning  in 1997 and  continuing  through  the first  quarter  of 1999,  the
company utilized increased  short-term  borrowing in lieu of increased long-term
borrowing  (other  than  long-term  debt  assumed  in  connection  with  the UTP
acquisition in 1998). While overall short-term borrowings were lower at December
31,  1999,  compared to December  31,  1998,  the company  remained in a working
capital  deficit  position  (currently  $1.0  billion  at  December  31,  1999).
Depending  upon the revenues  earned and cash  received  from the sale of assets
during 2000,  the company may increase total  indebtedness  during the course of
the year.

  On January 27, 1999,  ARCO filed a Form S-3  Registration  Statement (S-3) for
the issuance of up to $1.5 billion of debt  securities  as  determined by market
conditions.  At  December  31,  1999,  ARCO had  issued a total of $1 billion of
long-term debt securities  under the S-3. As of February 28, 2000, the remaining
$500 million of debt securities that could be issued under the S-3 have not been
issued by the company.

  At  December  31,  1999,  ARCO had unused  committed  bank  credit  facilities
totaling $3.0 billion.

  The company  believes it has adequate  resources  and liquidity to fund future
cash requirements for working capital, capital expenditures,  dividends and debt
repayments  with  cash  generated  from  operations,   existing  cash  balances,
additional short-and long-term borrowing, and the sale of assets.

  Effective June 13, 1997,  ARCO had a 2-for-1 stock split in the form of a 100%
stock dividend and a 4% increase in the quarterly dividend.

  In March 1999,  Vastar  issued $300 million of debt  securities.  During 1999,
Vastar had a revolving credit facility of $1.1 billion.  The effective  interest
rate for the debt outstanding under this facility averaged 5.9% for the year. As
of December 31, 1999, no debt was outstanding under the facility.

               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.

  At  December  31, 1999 the company  held a variety of  financial  instruments,
derivative instruments, and derivative-commodity  instruments that are sensitive
to changes in interest rates, foreign exchange rates and commodity prices.

  To minimize the effects of interest  rate and foreign  currency  fluctuations,
ARCO  enters  into the  following  transactions  using  derivatives:  1) foreign
currency  forward,  option and swap  contracts;  2) interest rate swaps;  and 3)
financial  futures  contracts and  over-the-counter  Treasury  options which are
limited to investment  portfolio  hedging,  alteration of portfolio duration and
changing asset mix. ARCO and its subsidiaries also engage in hedging  strategies
involving forward and futures contracts,  swaps and options covering part of its
natural gas and crude oil production to minimize the effects of commodity  price
fluctuations.

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

  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 and
the fair value of notes  payable at December  31,  1999,  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 10% change in
interest rates, is not material.

  The fair value of the company's long-term debt,  including current maturities,
was estimated to be $5.9 billion at December 31, 1999, and exceeded the carrying
value by $211 million.  Market risk was estimated at $227 million,  representing
potential  increase in fair value resulting from a hypothetical  10% decrease in
the company's  weighted average  long-term  borrowing rate at December 31, 1999.
Interest rate risk is mitigated by the use of floating rate  instruments,  which
comprise  approximately  $435  million of the  company's  longterm  debt,  and a
LIBOR-based fixed-to-floating rate swap on $100 million of long-term debt.

Foreign Exchange Rate Risk

  The company  has bought  foreign  currency  contracts  (principally  involving
European  currencies) to hedge  anticipated  foreign  currency  commitments  and
future cash flows from overseas  operations with varying maturities ranging from
January 2000 to March 2000.

  The hypothetical loss in cash flows of the combined  foreign-exchange contract
positions is estimated to be $61 million.  A hypothetical  adverse change of 10%
in year-end exchange rates (a strengthening of the U.S. dollar), is assumed. For
purposes of the estimation, it was also assumed that the exercise of the foreign
currency  contracts and the  anticipated  commitments  or future cash flows took
place at the same  time  and at the  hypothetical  exchange  rate.  The  foreign
currency  amounts for the future cash flows were  translated to U.S.  dollars by
using  the  hypothetical  exchange  rate  and  the  cash  value  of the  option,
multiplied by the difference  between the hypothetical and strike exchange rates
to the option-contract amount.

  At December 31, 1999, approximately $580 million of short-term investments and
$845 million of short-term debt were denominated in foreign currencies. Assuming
a hypothetical adverse change of 10% in year-end exchange rates (a strengthening
of the U.S.  dollar),  the company would experience a net increase in cash flows
from the short-term investments and debt of approximately $57 million.

Commodity Price Risk

  From  time  to  time,   the  company   uses  various   hedging   arrangements,
predominantly natural gas swaps and crude oil futures and options, to manage the
company's  exposure  to price risk from its natural  gas and  petroleum  liquids
production.  These  hedging  arrangements  have 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 commodity, they also limit the
benefit the company  might  otherwise  have  received  from any price  increases
associated with the hedged commodity.

  At December 31, 1999,  ARCO had entered into a series of crude oil futures and
options contracts and a series of forward natural gas contracts.

  Based on year-end  forward  prices ARCO had a net  liability  of $1 million on
those contracts.  The hypothetical incremental loss in earnings for the combined
commodity  positions at year end is  estimated  to be $12  million,  assuming an
increase in crude oil and natural gas year-end forward prices of 10%.

  In order to calculate the  hypothetical  loss, the relevant  parameters of the
commodity  contracts  are the type of  commodity  and the  delivery  price.  The
hypothetical  loss on the commodity  contracts was estimated by calculating  the
cash value of the  contracts  as the  difference  between the  hypothetical  and
contract delivery prices, then multiplying it by the contract amount.

Equity Price Risk

  Other investments at December 31, 1999,  included marketable equity securities
which are recorded at fair value of $846 million, including net unrealized gains
of $376 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 $85 million.

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.

* 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 exceed
the amount  accrued by as much as $550 million.  This estimate was determined by
applying Monte Carlo  analysis to estimated site maximums on a portfolio  basis.
See Note 15 of Notes to Consolidated  Financial  Statements beginning on page 53
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, $1.2 billion
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. The company has
not yet completed evaluating the impact of the provisions of SFAS No. 133.

                  Safe Harbor for Forward-Looking Statements*

  ARCO's  management  from time to time may make  forward-looking  statements to
inform existing and potential  security holders regarding various matters.  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.

Likelihood of BP Amoco Combination

  The closing of the combination  with BP Amoco is subject to the outcome of the
pending litigation  brought by the FTC. See page 1 for a detailed  discussion of
the legal proceedings.

  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.

Level of Oil and Gas Prices

  ARCO's management makes assumptions about the future prices of oil and gas for
various  planning,  budgetary and  accounting  disclosure  purposes.  Management
expects that these  assumptions  will change over time and actual  prices in the
future may differ from these  estimates.  Any substantial or extended decline in
actual 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.

* The  company  desires  to  take  advantage  of the  "safe  harbor"  provisions
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.

                         Impact of the Year 2000 Issue

  The Year 2000 issue (Y2K) arose from computer  programs and embedded  computer
chips  being  unable to  distinguish  between  the year 1900 and the year  2000,
resulting in system  failures or  miscalculations  that could cause  operational
disruptions. The company's planning for possible Y2K disruptions was successful,
as no major  problems  occurred.  The few  incidents  that did occur  during the
actual  transition  from 1999 to 2000 were quickly  analyzed,  resolved,  and/or
contingency plans implemented and had only minimal business impacts.

  ARCO addressed its Y2K efforts in four phases: (1) inventory of Y2K items; (2)
assessment  of  criticality  of these items and  prioritization  of  remediation
efforts;  (3)  evaluation  of  various  remediation  strategies;   and  (4)  the
remediation and testing of modifications or new software.

                  Notes to Consolidated Financial Statements

Note 1 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
subsidiaries, ventures and partnerships in which a controlling interest is held,
including Vastar  Resources,  Inc., of which ARCO owned 81.9% of the outstanding
shares at December 31, 1999. 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 securities,
maturing within three months of purchase.  Cash  equivalents are stated at cost,
which approximates fair value.

Oil and Gas Unproved Property Costs

  Unproved  property  costs  are  initially  capitalized.  Significant  unproved
properties are not amortized but are periodically assessed for impairment. Other
unproved properties are amortized on a composite basis, considering past success
experience  and  average   property  life.  In  general,   costs  of  properties
surrendered or otherwise  disposed of are charged to  accumulated  amortization.
Costs  of  successful   properties  are  transferred  to  developed  properties.
Exploratory  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
capitalized 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.

                  Notes to Consolidated Financial Statements

Stock-based Compensation

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

Earnings per Share

  Basic  earnings  per share is based on the  average  number  of common  shares
outstanding  during  each  period.   Diluted  earnings  per  share  includes  as
outstanding certain  contingently  issuable shares,  primarily stock options and
convertible  preference stock. All earnings per share have been restated to give
effect to the 100% stock dividend effective June 13, 1997.

Use of Estimates

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

Derivative Instruments

  The company  uses 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 does not hold or issue derivative
instruments  for trading  purposes and is not a party to leveraged  instruments.
All derivative  instruments  are off-balance  sheet  instruments;  however,  net
receivable or payable positions related to derivative instruments are carried on
the balance sheet.  The nature of the  transaction  underlying a risk management
strategy,  primarily  whether  or  not  the  instrument  qualifies  as a  hedge,
determines which accounting method is used.

  In order to qualify for hedge  accounting,  the derivative  instrument must be
designated and effective as a hedge.

  Deferral  accounting is used for the following types of  transactions  (if the
instrument  qualifies as a hedge):  future crude oil and natural gas production;
fixed-price  crude oil and  natural  gas  purchase  and sale  commitments;  U.S.
dollar-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  are  included  in other  assets or accrued
liabilities  until the  designated  underlying  item is  recognized  in  income.
Recognized gains and losses are 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 are crude
oil and natural gas swap and price collar  contracts  and some foreign  currency
swap, forward and option contracts.

  The accrual  method of accounting  is 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  is  recognized  in income in the period to which the
payment or receipt relates.  Amounts to be paid/received  under these agreements
are recognized as an adjustment to interest expense. The related amounts payable
to/receivable from the counterparties are included in other accrued liabilities.

  The fair value method of accounting is used for any derivative instrument that
does not qualify as a hedge.  The fair value  method,  whereby  gains and losses
associated with changes in fair value of a derivative  instrument are recognized
currently in income or in accumulated  other  comprehensive  income, is 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.
Presently,  changes in fair value of all  transactions  accounted for under this
method are 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  are reported as cash
flows from operations.

<PAGE>

                  Notes to Consolidated Financial Statements

  If a  derivative  instrument  designated  as a hedge  is  terminated  prior to
expected maturity,  gains or losses are deferred and included in income when the
underlying hedged item is recognized in income.

  When the designated item associated with a derivative  instrument  matures, is
sold, extinguished or terminated,  gains or losses are recognized as part of the
gain or loss on sale or settlement  of the  underlying  item.  When a derivative
instrument  is  associated  with an  anticipated  transaction  that is no longer
expected to occur, the gain or loss on the derivative is recognized  immediately
in income.

Reclassifications

  Certain  previously   reported  amounts  have  been  restated  to  conform  to
classifications adopted in 1999.

Note 2 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 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 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.

  Intersegment sales were made at prices approximating current market value.

Note 3 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.

  The liabilities  assumed included  employee  termination costs of $78 million.
The group of employees terminated included U.S. citizens employed in exploration
and production  operations and corporate  headquarters  personnel.  In the third
quarter of 1999 ARCO recorded an additional $8 million provision for termination
of UTP employees to reflect an increase in the estimated  costs. At December 31,
1999, ARCO had terminated 353 of the 357 employees to be terminated and had paid
out $82 million of the $86 million provided for severance payments.

  Liabilities  assumed also included 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.  Approximately  half of the cash costs were paid in 1999. All remaining
cash costs for severance, office lease and software maintenance contract buyouts
are expected to be paid out by the end of 2000.

  The following  unaudited pro forma summary presents  information as if UTP had
been acquired as of the beginning of ARCO's fiscal years 1998 and 1997.  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 4 Discontinued Operations

Coal

  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

<PAGE>

                  Notes to Consolidated Financial Statements

  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
additional 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
after-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.

  In September  1997,  ARCO  disposed of its 49.9% equity  interest in Lyondell.
ARCO recorded an after-tax gain of $291 million on the disposition.

  Revenues and net income from discontinued operations were as follows:

Note 5 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.

  Effective January 1, 1997, ARCO adopted SOP 96-1,  "Environmental  Remediation
Liabilities."  The  provisions  include  standards  affecting  the  measurement,
recognition and disclosure of environmental remediation liabilities.  The effect
of initially  applying the  provisions of SOP 96-1 in 1997 was a decrease in net
income of $30 million ($0.09 per share).

Note 6 Extraordinary Item

  During 1997,  ARCO  retired  debt with a face value of $756  million  prior to
maturity.  The debt  repurchases  resulted  in an  extraordinary  charge of $118
million against net income, after tax of $74 million.

<PAGE>
                  Notes to Consolidated Financial Statements

Note 7 Restructuring Costs

  During 1998,  ARCO recorded  pre-tax  charges of $229 million for the costs of
eliminating  over  1,200  positions  related  to the  downsizing  of  continuing
operations,   primarily  E&P  technical   support,   international  E&P  support
operations and the corporate headquarters. These 1,200 positions eliminated were
specifically identified prior to December 31, 1998. During 1999, the reserve was
increased by $12 million, primarily to reflect additional terminations.

  The  following  table   summarizes  the   liabilities   related  to  the  1998
restructuring  program,  including $11 million transferred from the 1997 program
discussed below:

</TABLE>

(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.

  Long-term  benefits will be paid after  retirement over the remaining lives of
the recipients or, for pension benefits, in a lump sum upon election.  Long-term
benefits  have been accrued in  accordance  with SFAS No. 88. As of December 31,
1999,  approximately  1,160 employees have been terminated and approximately $73
million  of the  short-term  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 first quarter 2001.

  In  addition,  in 1998 the  company  recorded a pre-tax  charge of $20 million
related  to office  space and  facilities  that will be  vacated  with no future
economic benefit. Cash payments will be made through 2005, the remaining term of
the lease.

  During  1997,  ARCO  recorded  pre-tax  charges of $67 million  for  personnel
reductions in refining and marketing operations and corporate  headquarters.  As
of December 31, 1999,  $53 million was paid and $11 million was  transferred  to
reserves  for the 1998  program,  with a balance of $3 million  remaining  to be
paid.  The transfer was necessary  because when the 1998 program was  announced,
certain  employees  who had not yet  terminated  under the 1997  program  became
eligible for 1998 program benefits.  Approximately 480 employees were originally
planned to terminate under the 1997 program.  About 400 people  terminated under
the 1997 program, with the remainder transferred to the 1998 program.

Note 8 Inventories

  Inventories  are recorded when  purchased,  produced or  manufactured  and are
stated  at  the  lower  of  cost  or  market.  In  1999,  approximately  76%  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:

</TABLE>
  The  excess  of  the  current  cost  of   inventories   over  book  value  was
approximately  $246  million  and $193  million at  December  31, 1999 and 1998,
respectively.

Note 9 Investments

  At December 31, 1999 and 1998,  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, 1999 and 1998,
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.

</TABLE>

  Expenses  for  maintenance  and  repairs  for  1999,  1998 and 1997  were $292
million, $387 million and $334 million, respectively.

  In the fourth quarter of 1998, after a year-long  decline in crude oil prices,
ARCO  determined  that part of the oil price  decline  that had taken  place was
permanent.  Accordingly, ARCO revised its official crude oil price forecast used
for  economic  decision  making.  This  forecast  was  based  on  a  West  Texas
Intermediate  (WTI)  benchmark  price of $15/bbl in 1999,  $16/bbl in 2000,  and
$17/bbl in 2001, with 2% escalation  thereafter.  While crude oil prices reached
as low as $12/bbl in December 1998, many oil industry expert forecasts  consider
crude  oil  prices  in that  range to be  unusually  low and  inappropriate  for
economic decision making.

  In accordance  with SFAS No. 121, in 1998 ARCO performed an impairment  review
to determine whether any of ARCO's oil and gas properties were impaired based on
the new crude oil price forecast.  Net  undiscounted  cash flows before tax were
calculated and compared to the net book value on a  field-by-field  basis.  This
included cash flows from proved developed,  proved undeveloped and potential oil
and gas reserves,  which included both producing and non-producing reserves. The
potential  reserves  were  calculated  on a  risk-weighted  basis to include the
uncertainties  associated with field size, reservoir performance,  technological
development and commercial risk. Where appropriate,  contracted prices were used
but did not  materially  impact the result.  For those fields where the net book
value exceeded the net undiscounted cash flows before tax, the discounted future
cash flows before tax were  calculated  using a 10% discount  rate factor.  This
resulted in a pre-tax  impairment  charge of $1.4 billion in 1998. ARCO tested a
downside  case using WTI  benchmark  crude oil prices of $1/bbl  lower than each
year of its official  forecast.  ARCO believes that prices below $14/bbl are not
sustainable  and like  most  commodities  will  cycle  around  their  historical
midpoints.  The impaired  properties included former UTP properties in Pakistan,
Venezuela  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.

Note 11 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.   The  weighted  average  interest  rate  on  notes  payable
outstanding at December 31, 1999 and 1998, was 6.0% and 5.6%, respectively.

  At December 31, 1999, ARCO had unused letters of credit totaling approximately
$398 million.

<PAGE>

                  Notes to Consolidated Financial Statements

  In 1999, ARCO and certain wholly owned  subsidiaries had committed bank credit
facilities of approximately  $3.1 billion.  At December 31, 1999, there were $57
million of borrowings under these committed facilities.

Note 12 Long-term Debt

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

  In 1996, Vastar  consolidated  existing unsecured  revolving credit agreements
into a  single  facility.  As of  December  31,  1999,  commitments  under  this
facility, as amended to date, totaled $1.1 billion. The commitment expires March
31, 2002. As of December 31, 1999, no debt was outstanding  under this facility.
The effective rate of borrowings  under this facility during 1999 averaged 5.9%.
The credit facility is not guaranteed by ARCO. The agreement contains covenants,
the most  restrictive  of which  require  Vastar to maintain  certain  financial
ratios  and  minimum  levels  of  tangible  stockholders'  equity  and  restrict
encumbrance of assets.

  In April 1998,  Vastar  issued $100 million of 6%  Putable/Callable  Notes due
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 in 1999 was 5.3%. The financial impact of swaps in 1999
and 1998 was immaterial.

  Approximately $3 million and $247 million of long-term debt was denominated in
foreign currencies at December 31, 1999 and 1998, respectively.

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

Note 14 Financial Instruments and Fair Value

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

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

  At December  31,  1999,  the notional  amounts of foreign  currency  contracts
outstanding  (principally involving European currencies) were $633 million, with
various  maturities  in 2000.  At December  31, 1998,  the  notional  amounts of
foreign currency contracts outstanding were $528 million.

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

  ARCO also uses various  hedging  arrangements  to manage the exposure to price
risk for  future  natural  gas and crude  oil  transactions.  Gains  and  losses
resulting from these  transactions  are deferred and included in other assets or
accrued  liabilities until realized in sales and other operating revenues as the
physical production required by the contracts is delivered.

  During 1999,  Vastar  entered into a series of natural gas and crude oil price
collar and put  agreements.  At December 31, 1999,  natural gas collars and puts
sold covering an average of 400 million cubic feet per day of production were in
place for the period  January 2000 through  March 2000.  These  agreements  will
serve as hedges which secure  weighted  average prices on these volumes  between
$2.54 and $3.27 per thousand cubic feet (on a Henry Hub basis) for market prices
in excess of  $2.12/mcf.  Crude oil collars and puts sold  covered an average of
23,000  barrels  per day of  production  for the  period  January  2000  through
December  2000.  These  agreements  will serve as hedges which  secure  weighted
average prices on these volumes  between $18.80 and $23.31 per barrel for market
prices in excess of $15.80 per barrel.

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

                  Notes to Consolidated Financial Statements

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

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

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

Note 15 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 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
$2.2 to $2.4 billion.

  Following the March 1989 EXXON VALDEZ oil spill,  numerous federal,  state and
private plaintiff lawsuits were brought against Exxon,  Alyeska Pipeline Service
Company  (Alyeska) and Alyeska's owner  companies,  including  ARCO,  which owns
approximately  22%.  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,  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  liability  pursuant  to various  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
federaland 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 130 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.

<PAGE>
                  Notes to Consolidated Financial Statements

  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, 1999 was $686  million.  As these  costs  become more  clearly
defined, they may require future charges against earnings.  Applying Monte Carlo
analysis to estimated  site maximums on a portfolio  basis,  ARCO estimates that
future costs could exceed the amount accrued by as much as $550 million.

  Approximately  60% 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 11% of the total accrual.  No other site represented more than
7% of the total  accrual.  The  remainder  related to other sites with  reserves
ranging  from $1 million to $10  million  per site.  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.

  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 17 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 has the right to  terminate or modify the plans at
any time.

of health care  benefits was assumed for 1997 to 2001,  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
pension  plans that provide  retirement  benefits in excess of current  Internal
Revenue 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 $343 million and $299 million at
December  31, 1999 and 1998,  respectively,  and is included in "other  deferred
liabilities and credits" on the balance sheet. The liabilities for non-qualified
pension plans and deferred  compensation  are unfunded  based on  definitions 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 $572 million and $541  million at December 31, 1999 and 1998,  respectively,
and is included in "deferred charges and other assets" on the balance sheet.

Note 18 Lease Commitments

  Capital lease  obligations  are recorded at the present value of future rental
payments. The related assets are amortized on a straight-line basis.

  At December 31, 1999,  future minimum rental payments due under leases were as

Note 19 Stock Options

  Options  to  purchase  shares of ARCO's  common  stock  have been  granted  to
executives,  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  prior to 1997 vest over two years in
equal installments.  Options granted subsequently vest equally over three years.
Transactions during 1999, 1998 and 1997 were as follows (restated to give effect
to June 13, 1997 100% stock dividend):

  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.

  During 1999 and 1998,  respectively,  236,412 and 184,488 shares of contingent
restricted  stock were awarded at weighted  average prices of $56.81 and $74.00,
net of forfeitures and retirements, with varying evaluation periods. During 1999
and 1998,  28,696 and 135,180 shares of restricted stock were issued at weighted
average prices of $56.81 and $73.93, respectively.

  During  1999,  1998 and 1997,  $21 million,  $10 million,  and $23 million was
recognized as expense for performance-based restricted stock, respectively.

  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. In connection with the disposition, ARCO recorded
an impairment  writedown of $147 million  before tax, or $114 million after tax,
that was included in the impairment  discussed in Note 10. 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.

  Excluded  from the  Consolidated  Statement  of Cash  Flows for the year ended
December  31,  1997 was ARCO's  use of  Lyondell  common  stock to redeem its 9%
Exchangeable Notes with an outstanding principal amount of $988 million.

Note 22 Foreign Currency Transactions

  Foreign currency transactions resulted in net losses of $1 million, $2 million
and $12 million in 1999, 1998 and 1997, respectively.

Note 24 Comprehensive Income

  Effective  January 1, 1998,  the  company  adopted  SFAS No.  130,  "Reporting
Comprehensive  Income,"  which  established  new  rules  for  the  reporting  of
comprehensive  income and its  components.  Comprehensive  income  comprises net
income  plus  all  other  changes  in  equity  from  nonowner  sources.  The new
disclosures   had  no  impact  on  ARCO's  net   income,   financial   position,
stockholders' equity or cash flows.

  The related tax effects  allocated to each  component  of other  comprehensive
income at December 31 were as follows:

                     Supplemental Information (Unaudited)

Oil and Gas Producing Activities

  The  Securities  and  Exchange  Commission  (SEC)  defines  proved oil and gas
reserves as those  estimated  quantities of crude oil,  natural gas, and natural
gas liquids 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 ARCO  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,  1999  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 11% of petroleum
liquid proved reserves.

  ARCO has no  long-term  supply  contracts  to  purchase  petroleum  liquids or
natural gas from foreign governments.

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

  /1/Comprises  reserves  attributable  to ARCO's  ownership  interest in equity
affiliates.

<PAGE>

                     Supplemental Information (Unaudited)

  Included in ARCO's  reserves  are 100% of the  reserves of Vastar,  a consoli-
dated  subsidiary  of which ARCO owned 81.9% at December 31, 1999.  Vastar's re-
serves  comprised  11% and 51% of U.S.  petroleum  liquids  and  natural gas re-
serves, respectively, at December 31, 1999.

  During 1999, net reserve additions  replaced 129% of worldwide  oil-equivalent
production. During the three-year period 1997-1999, ARCO's net reserve additions
replaced 163% of worldwide oil-equivalent production.

  Reserve  additions in 1999 were spread  fairly evenly  among:  extensions  and
discoveries (primarily exploration successes in the Gulf of Mexico deepwater and
Alaska);  purchases (primarily in the  Malaysia-Thailand  Joint Development Area
and a field under a risked service contract in Venezuela); and revisions.

  Including contracts acquired with UTP, 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.

  Natural gas from the North Slope of Alaska,  other than that used in providing
fuel in North  Slope  operations  or sold to others on the North  Slope,  is not
presently economically marketable.

  ARCO is actively  evaluating  various  technical  options for  commercializing
North Slope gas.  Among the options  being studied are the  construction  of gas
transportation and liquefied natural gas (LNG) manufacturing  facilities and the
development of a gas-to-liquids  conversion  process.  ARCO is also working with
the State of  Alaska to  enhance  the  fiscal  and  regulatory  climate  for the
ultimate  commercialization of North Slope gas resources.  Significant technical
uncertainties  and  existing  market  conditions  still  preclude  gas from such
potential projects being included in ARCO's reserves.

  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  difference  between  the above  results  of  operations  and the  amounts
reported for exploration and production segment net income in Note 2 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, in 1998,
restructuring costs related to oil and gas operations.

  The standardized measure of discounted estimated future net cash flows related
to proved oil and gas reserves at December 31 was as follows:

  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.  Benchmark prices used in preparing the
Supplemental  Oil and Gas Information  were $25.60,  $12.05,  and $17.64 for the
years ended December 31, 1999, 1998 and 1997, respectively.

  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.

and $10  million  after tax on  Refining  and  Marketing  earnings  in the first
quarter 2000 and 1999, respectively.

NOTE G.  CAPITALIZATION OF INTEREST.

  Interest expense excludes  capitalized interest of $36 million and $39 million
for the three-month periods ended March 31, 2000 and 1999, respectively.

NOTE H.  RESTRUCTURING PROGRAMS.

  Through December 31, 1999, the company had established reserves totalling $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 March 31, 2000, approximately 1,200 employees have been terminated and
approximately $88 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.

UNION TEXAS PETROLEUM HOLDINGS, INC. (UTP) RESTRUCTURE.

  Through December 31, 1999, the company established a $90 million provision for

NOTE N.       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 $2.2 to $2.4 billion.

  Following the March 1989 EXXON VALDEZ oil spill,  numerous federal,  state and
private plaintiff lawsuits were brought against Exxon,  Alyeska Pipeline Service
Company  (Alyeska),  and Alyeska's  owner companies  including ARCO,  which owns
approximately  22%.  While  all of the  federal,  state  and  private  plaintiff
lawsuits have been  settled,  certain  issues  relating to the 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 the 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 of alleged  injuries to natural
resources  resulting  from mining and  mineral  processing  businesses  formerly
operated by Anaconda. In April 1998, ARCO entered two consent decrees,  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  liability  pursuant  to various  federal,  state and local
environmental  laws and  regulations  that require ARCO to do some or all of the
following:

o    Remove or mitigate the effects on the environment at various sites from the
     disposal or release of certain substances;

o    Perform restoration work at such sites; and

o    Pay damages for loss of use and non-use values.

  The federal  agencies  involved with the sites  included 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 130 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 share of 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:

o    Nature and extent of contamination;

o    Timing, extent and method of remedial action;

o    ARCO's proportional share of costs; and

o    Financial condition of other responsible parties.

  The environmental  remediation accrual is updated annually,  at a minimum, and
at March 31, 2000, was $686 million. As these costs become more clearly defined,
they may require future charges against earnings.  Applying Monte Carlo analysis
to estimated  site maximums on a portfolio  basis,  ARCO  estimates  that future
costs could exceed the amount accrued by as much as $550 million.

  Approximately  60% 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 11% of the total accrual.  No other site represented more than
7% of the total  accrual.  The  remainder  related to other sites with  reserves
ranging  from $1 million to $10  million  per site.  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.

                       STATEMENTS - UNAUDITED--(CONTINUED)

NOTE N.       OTHER COMMITMENTS AND CONTINGENCIES (CONTINUED)

  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.

  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 O.       SUBSEQUENT EVENTS

MERGER OF ARCO INTO BP AMOCO P.L.C.  AND CHANGE OF CONTROL OF ARCO

  On April 18, 2000, the combination of BP Amoco p.l.c.  (BP Amoco) and ARCO was
completed by the merger of Prairie  Holdings,  Inc. (a  subsidiary  of BP Amoco)
with and into ARCO,  pursuant to the terms of the merger  agreement  dated March
31, 1999, as amended through March 8, 2000 (Merger  Agreement).  Pursuant to the
Merger Agreement,  each share of outstanding  common stock of ARCO (save for any
such shares owned by BP Amoco,  ARCO or any  subsidiary of BP Amoco or ARCO) was
converted into the right to receive 1.64 BP Amoco American  Depositary  Receipts
(ADRs) or,  subject to the timely receipt of elections  therefor,  9.84 BP Amoco
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.

  ARCO's outstanding shares of $2.80 and $3.00 Preference Stock remain listed on
the New York Stock  Exchange.  Pursuant to the Merger  Agreement,  each share of
$2.80  Preference  Stock was converted  into the right to receive 7.872 ADRs and
each share of $3.00  Preference  Stock was  converted  into the right to receive
22.304  ADRs.  ARCO  remains a  reporting  company  within  the  meaning  of the
Securities and Exchange Act of 1934.

  In  connection  with the merger,  on April 18, 2000,  ARCO issued  324,711,290
shares  of  common  stock  to BP  Amoco.  Later  on  April  18,  2000,  BP Amoco
transferred all such shares to BP America, Inc., a wholly owned subsidiary of BP
Amoco, so that BP Amoco 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 Amoco is the controlling shareholder of ARCO.

  Included in the merger agreement was a provision requiring BP Amoco to keep in
place for two years  following  the merger  ARCO's  change of control  severance
programs.  The  benefits  associated  with those  programs  will  result in ARCO
recording later in the year a potentially  significant charge for ARCO employees
who are terminated in the next two years as a result of the merger. In addition,
there will be charges for other merger related costs.

SALE OF ALASKAN BUSINESSES

  On  March  15,  2000  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 prices  realized on production  subsequent to December
31, 1999). 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. The major portion of
the sale closed on April 26, 2000.  The  remainder of the assets are expected to
be transferred upon receipt of governmental approvals.

became a wholly owned  subsidiary of BP Amoco.  As indirect  owner of all of the
outstanding  shares  of  common  stock  of ARCO,  BP  Amoco  is the  controlling
shareholder  of  ARCO.  (See  Note O. to the  financial  statements  and  Item 5
beginning on page 18 of this Report on Form 10-Q).

FIRST QUARTER 2000 VS. FIRST QUARTER 1999

CONSOLIDATED EARNINGS

  The $452 million increase in net income in the first quarter of 2000 reflected
higher crude oil prices, and to a lesser extent, higher U.S. natural gas prices.
These  factors  were  partially  offset  by  lower  crude  oil and  natural  gas
production  volumes,  as well as higher  operating and  exploration  expense and
lower earnings from the refinery and marketing segment.

  A net special items benefit in the first quarter 2000 totalled $34 million and
consisted  of  net  gains  on  asset  sales,  partially  offset  by a  provision
associated with a patent  lawsuit,  BP Amoco merger costs and charges for future
environmental remediation.

  For the first quarter of 1999,  net special  items charges  totaled $7 million
and consisted primarily of charges for future environmental remediation.

EXPLORATION AND PRODUCTION

  ARCO's  earnings  from  worldwide  oil  and  gas  exploration  and  production
operations in the first quarter 2000 were significantly impacted by higher crude
oil prices and,  to a lesser  extent,  higher U.S.  natural gas prices and lower
operating  expenses.  These factors were partially offset by lower crude oil and
natural gas  production  volumes and increased  exploration  expense.  Operating
expenses were $17 million  lower in the first  quarter of 2000,  compared to the
same  period in 1999.  The  earnings  in the first  quarter  of 2000  included a
special item benefit of $58 million after tax from assets  sales.  There were no
special items in the first quarter of 1999.

  In 2000, the reduction in U.S. petroleum liquids production primarily resulted
from natural field  declines in Alaska and the effect of higher crude oil prices
on the ARCO Long Beach , Inc. production contract.  The decreased  international
petroleum  liquids volumes primarily  reflected lower  Indonesian,  Tunisian and
United Kingdom North Sea production  volumes.  The Indonesian  decrease resulted
from the impact of higher crude oil prices on production sharing contracts.  The
decreased Tunisian production reflected the sale of the Ashtart field, which was
effective  January 1, 2000.  The decrease in United Kingdom North Sea production
resulted from natural field decline.

  The increase in international  natural gas volumes in 2000 primarily reflected
higher production in Indonesia and the Yacheng 13 field in China offset by a net
decrease in United  Kingdom  North Sea  production of  approximately  30 million
cubic feet per day due to natural field decline. The first quarter 2000 decrease
in U.S. natural gas volumes  reflected lower  production from Vastar  Resources,
Inc.  (Vastar),  which is 81.9 % owned  by ARCO.  The  lower  Vastar  production
resulted from natural field declines and asset sales during the last nine months
of 1999.

  ARCO's  exploration and production  earnings and petroleum liquids  production
will decline  significantly with the sale of Alaskan businesses to Phillips (see
Sale of Alaskan businesses).

REFINING AND MARKETING

  In the first  quarter  of 2000,  refining  and  marketing  earnings  decreased
primarily as a result of the establishment of a reserve for a patent lawsuit and
higher  refinery  turnaround  costs.  In  addition,  higher crude oil costs were
mostly,  but not completely,  offset by increased  retail  marketing  prices and
volumes.

  The  amortization  associated with the deferral of part of the pre-tax gain on
the sale of the ARCO  Chemical  interest in 1998 had a net  favorable  impact of
approximately  $12 million and $10 million  after tax on refining and  marketing
earnings in the first quarter of 2000 and 1999, respectively.  See the Company's
Annual  Report on Form 10-K for the year ended  December  31, 1999 for a further
discussion of the deferred gain.

OTHER OPERATIONS

  The 2000 and 1999 results from ARCO's other  operations  included the earnings
from Lower 48 pipeline  operations and an aluminum rolling  facility.  The lower
pipeline  earnings  reflected a decrease in volumes for the Seaway  pipeline and
losses incurred on the Olympic Pipeline.

DISCONTINUED OPERATIONS

  In June of 1998, ARCO disposed of its U.S. coal operations.  As of March 1999,
ARCO  sold its  interests  in three  Australian  coal  mines.  ARCO sold its 80%
interest in the  Gordonstone  coal mine,  its 31.4%  interest in the Blair Athol
Joint Venture and its stake in the Clermont coal deposit. At March 31, 2000, the
Company's  discontinued  operations  consisted  of one  remaining  coal  mine in
Australia.

  In  March  1999,   ARCO  sold  its  wholly  owned   subsidiary,   Union  Texas
Petrochemicals  obtained  during the 1998  acquisition of Union Texas  Petroleum
Holdings, Inc.

  ARCO had no earnings  from  discontinued  operations  in the first  quarter of
2000,  because  income or loss from the remaining  Australian  coal operation is
being deferred as part of net assets from discontinued operations on the balance
sheet at March 31, 2000.

</TABLE>

  The increase in exploration and production sales and other operating  revenues
resulted  primarily  from higher crude oil prices and, to a much lesser  extent,
higher  domestic  natural gas prices.  Refining  and  marketing  sales and other
operating  revenues  increased  primarily  because  of higher  refined  products
prices, and to a lesser extent, higher gasoline volumes.

CONSOLIDATED EXPENSES

  Trade purchases were higher in the first quarter of 2000 primarily as a result
of higher crude oil prices and, to a lesser extent,  higher purchased volumes of
finished refined products.

  The  increase in  operating  expenses in the first  quarter of 2000  reflected
refining and marketing  expenses  associated with the establishment of a reserve
for a patent lawsuit and higher refinery  turnaround  costs.  These factors were
partially  offset  by a  decline  in  exploration  and  production  and Lower 48
pipeline operating expenses related to the Company's cost reduction programs.

  The lower selling,  general and administrative expenses in 2000 were primarily
in the corporate  (unallocated) and refining and marketing segments and resulted
from the Company's cost reduction programs.

  The increase in  exploration  expense in the first  quarter 2000 resulted from
higher  dry  hole  expense  due to the  write-off  of two  offshore  wells  (one
deepwater well and one shelf well).

  The increase in taxes other than income taxes in 2000 primarily  resulted from
the impact of higher crude oil prices on U.S. production taxes, partially offset
by lower production volumes.

INCOME TAXES

  The Company's effective tax rate was 30.0% in the first quarter 2000, compared
to 35.6% in the 1999 first quarter.  The effective tax rate in the first quarter
of 2000 was lower than the federal  statutory  rate,  primarily as a result of a
lower effective tax rate associated with the sale of certain foreign properties.

</TABLE>

  The net cash used by investing  activities  in the first quarter 2000 included
expenditures  for  additions to fixed  assets of $619 million and proceeds  from
asset sales of $446 million  (approximately  $360 million  associated with asset
sales of foreign properties). The Company expects total capital expenditures for
additions  to fixed assets to  approximate  $2.1 billion for the full year 2000.
The budget was revised downward to give effect to the sale of the Alaskan assets
in April 2000.

  The net  cash  used by  financing  activities  in the  first  quarter  of 2000
included  repayments of short-term debt of $186 million and dividend payments of
$232 million.

  Cash and cash equivalents and short-term investments totaled $1.3 billion, and
short-term borrowings were $1.5 billion at the end of the first quarter of 2000.

  Beginning  in 1997 and  continuing  through  the first  quarter  of 1999,  the
Company utilized increased  short-term  borrowing in lieu of increased long-term
borrowing  (other  than  long-term  debt  assumed  in  connection  with  the UTP
acquisition in 1998).  As a result the Company is in a working  capital  deficit
position of $613 million at March 31, 2000.

  The Company  believes it has adequate  resources  and liquidity to fund future
cash requirements for working capital, capital expenditures,  dividends and debt
repayments with cash from operations,  existing cash balances, additional short-
and long-term borrowing,  cash infusions from ARCO's parent company BP Amoco and
the sale of assets.

SALE OF ALASKAN BUSINESSES

  On  March  15,  2000  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 realized  prices of production  subsequent to December
31, 1999).  Proceeds from the sale were advanced to BP Amoco. Under the purchase
and sale agreement,  which was amended on April 6, 2000, ARCO agreed to sell all
of the  outstanding  share 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.  The major  portion of the sale closed on April
26,  2000.  The  remainder  of the assets are  expected to be  transferred  upon
receipt of governmental approvals.

  Included in the merger agreement was a provision requiring BP Amoco to keep in
place for two years  following  the merger  ARCO's  change of control  severance
programs.  The  benefits  associated  with those  programs  will  result in ARCO
recording later in the year a potentially  significant charge for ARCO employees
who are terminated in the next two years as a result of the merger. In addition,
there will be charges for other merger related costs.

STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED

  In June 1998, the Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards  (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.  The Company has not yet
completed evaluating the impact of the provisions of SFAS No. 133.

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

  Management  cautions  against  projecting  any future results based on present
earnings  levels  because  of  economic  uncertainties,  the  extent and form of
existing  or future  governmental  regulations  and other  possible  actions  by
governments.
