NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

(1)  The consolidated financial statements included herein are unaudited and, in
     the opinion of  management,  include all  adjustments  necessary for a fair
     presentation  of  financial   position  and  results  of  operations.   All
     adjustments are of a normal recurring nature. Such financial statements are
     presented in  accordance  with the  Securities  and  Exchange  Commission's
     (Commission) disclosure requirements for Form 10-Q.

     These  interim   consolidated   financial  statements  should  be  read  in
     conjunction  with  the  consolidated  financial  statements  and the  Notes
     thereto  filed with the  Commission  in Unocal  Corporation's  1998  Annual
     Report on Form 10-K.

     Results for the nine months ended  September 30, 1999, are not  necessarily
     indicative of future financial results.

     Certain items in the prior year financial statements have been reclassified
     to conform to the 1999 presentation.

(2)  For the  purpose  of  this  report,  Unocal  Corporation  (Unocal)  and its
     consolidated subsidiaries, including Union Oil Company of California (Union
     Oil), are referred to as the company.

     The consolidated  financial  statements of the company include the accounts
     of  subsidiaries  in which a controlling  interest is held.  Investments in
     affiliates  without a controlling  interest are accounted for by the equity
     method.  Under the equity method,  the  investments are stated at cost plus
     the   company's   equity  in   undistributed   earnings  and  losses  after
     acquisition.  Income  taxes  estimated  to be  payable  when  earnings  are
     distributed are included in deferred taxes.

(3)  Other Financial Information

     During the third quarters of 1999 and 1998, approximately 51 percent and 40
     percent,   respectively,   of  total  sales  and  operating  revenues  were
     attributed to the resale of crude oil,  natural gas and natural gas liquids
     purchased  from  others  in  connection  with  the  company's  trading  and
     marketing  activities.  For the nine months  ended  September  30, 1999 and
     1998, approximately 48 percent and 34 percent, respectively, of total sales
     and operating  revenues were attributed to the resale of crude oil, natural
     gas and natural gas liquids  purchased from others.  Related purchase costs
     are  classified  as  expense  in the crude  oil,  natural  gas and  product
     purchases category on the consolidated earnings statement.

     Capitalized  interest  totaled  $4  million  and $5  million  for the third
     quarters of 1999 and 1998,  respectively.  Capitalized interest totaled $13
     million  and $22  million  for the  first  nine  months  of 1999 and  1998,
     respectively.

 (4) Income Taxes

     Income taxes on earnings  from  operations  for the third quarter and first
     nine  months  of 1999  were  $10  million  and $51  million,  respectively,
     compared  with $39 million and $177 million for the  comparable  periods of
     1998.  The  effective  income tax rate for the third quarter of 1999 was 29
     percent  compared with 52 percent for the third quarter of 1998.  The lower
     tax  rate  for  the   third   quarter   of  1999  was   primarily   due  to
     currency-related  tax adjustments in Thailand  partially  offset by the mix
     effect of domestic losses versus foreign earnings.

     The  effective  income  tax rate for the first  nine  months of 1999 was 56
     percent compared with 53 percent for the first nine months of 1998.

(UNAUDITED)

     Not included in the computation of diluted EPS were options  outstanding at
     September 30, 1999 to purchase  approximately  2.2 million shares of common
     stock.  These options were not included in the  computation as the exercise
     prices were greater than the  year-to-date  average  market price of $37.51
     for the common  shares.  The exercise  prices of these  options  range from
     $37.69 to $51.01 per share and they expire in 2007 through 2009.

(7)  Sale of Accounts Receivable

     In the second  quarter of 1999,  the  company,  through a  non-consolidated
     subsidiary Unocal Receivables Corp. ("URC"), entered into a sales agreement
     with  an  outside  party  under  which  it will  sell up to a $204  million
     undivided interest in domestic crude oil and natural gas trade receivables.
     The  company   continues  to  manage  the  collection  and   administrative
     responsibilities for accounts receivable  including the sold interest.  The
     effect  to the  company  of  the  interests  sold  in  its  domestic  trade
     receivables  under this  agreement is $95 million as of September 30, 1999.
     The amount sold is reflected as a reduction of accounts  receivable  in the
     consolidated balance sheet and in net cash provided by operating activities
     in the consolidated statement of cash flows.

(8)  Long Term Debt and Credit Agreements

     During the third  quarter,  the  company  increased  its  commercial  paper
     borrowings by $85 million to a total outstanding balance of $125 million at
     September 30, 1999. In addition,  the company also increased its borrowings
     under its limited recourse project financing for its Azerbaijan  activities
     by $11 million to an  outstanding  balance of $55 million at September  30,
     1999.

     Proceeds  from the  issuance  of  commercial  paper  were used for  general
     corporate  purposes including the refinancing of existing debt. The company
     retired  $22  million  in  maturing   medium-term  notes  and  reduced  its
     borrowings  under its $1 billion bank credit agreement by $40 million to an
     outstanding balance of $60 million at September 30, 1999.

(9)  Financial Instruments

     The estimated fair value of the company's long-term debt was $2,869 million
     on September 30, 1999. The fair values of the debt  instruments  were based
     on the  discounted  amounts of future cash outflows  using rates offered to
     the company for debt with similar  maturities.  The estimated fair value of
     the  mandatorily   redeemable   convertible  preferred  securities  of  the
     company's  subsidiary  trust  was  $566  million.  The  fair  value  of the
     preferred  securities  was based on the  trading  prices  of the  preferred
     securities on September 30, 1999.

     The  company's  financial  instruments  at September 30, 1999 are described
     below:

     Foreign exchange contracts - The company and its subsidiaries have assorted
     currency swap agreements outstanding that are designed to hedge the impacts
     of  foreign-currency  exchange-rate  fluctuations on US dollar- denominated
     debt. In the third quarter of 1999, the company received income tax refunds
     in Canada  equivalent  to  approximately  US$49  million as a result of the
     company's reinvestment of the proceeds from the 1998 sale of its investment
     in the stock of Tarragon  Oil and Gas Limited  into the stock of  Northrock
     Resources Ltd. The refund was used to retire approximately US$40 million of
     the  US$100  million  debt  outstanding  of one of the  company's  Canadian
     subsidiaries.  As a result of the debt retirement,  the subsidiary  reduced
     its related  currency swap  agreement from US$100 million to US$60 million.
     The agreement now requires the subsidiary to pay approximately C$88 million
     at maturity in exchange for US$60 million.  The parent company also reduced
     its  corresponding  currency swap  agreement  from US$100 million to US$ 60
     million.  This  agreement,   which  effectively  offsets  the  subsidiary's
     agreement, now requires the parent company to pay US$60 million in exchange
     for  C$88  million  at  maturity.  The  combined  fair  values  of the swap
     agreements outstanding at the end of the period were approximately zero.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(UNAUDITED)

     Other outstanding  currency swap agreements require the company's Northrock
     subsidiary to pay  approximately  C$115 million at maturity in exchange for
     US$75 million.  The fair values of these  agreements were US$72 million and
     were  determined by comparing the swap rates to the forward rates in effect
     at  September  30,  1999.  The  company's  share of the  estimated  pre-tax
     deferred  losses related to the US$75 million  currency swap agreements was
     US$1 million at September 30, 1999 (net of minority  interests).  The US$75
     million  to  be   received  by   Northrock   will  be  used  to  retire  US
     dollar-denominated debt at maturity.

     Northrock  also  has US  dollar  forward  contracts  outstanding  that  are
     designed  to  mitigate  its  exposure  to the US  dollar-indexed  prices it
     receives for the sale of its crude oil.  These  contracts  are subject,  in
     some  cases,  to  extensions  at  the  counterparty's  option  and  require
     Northrock   to  sell   approximately   US$200   million  in  exchange   for
     approximately C$285 million at maturity.  At September 30, 1999,  contracts
     of US$8  million  were  scheduled  to  mature  in 1999  with the  remaining
     contracts scheduled to mature periodically  through the year 2005. The fair
     values of the contracts were approximately  US$194 million. The fair values
     were  determined  by comparing  the contract  rates to the forward rates in
     effect at September  30, 1999.  The  company's  share of estimated  pre-tax
     unrealized  losses  relating  to  these US  dollar  forward  contracts  was
     approximately   US$3  million  at  September  30,  1999  (net  of  minority
     interests).

     During the  quarter,  the company  entered  into two forward  contracts  to
     purchase  Thai baht.  The  contracts  are  designed to hedge the  company's
     foreign-currency  exchange-rate  exposure  related to  expected  income tax
     payments to be paid to Thailand in 2000. The contracts  require the company
     to purchase 802 million baht at maturity in exchange for US$20 million. The
     fair value of the contracts at September 30, 1999 approximated the notional
     amounts.

     Other  commodity-based  contracts - Northrock had various  fixed-price  and
     fixed-price differential sales contracts outstanding at September 30, 1999,
     related to the future  sale of its natural gas  production.  The  contracts
     cover production, which averages 40 million cubic feet per day (mmcfpd) for
     the  remainder of 1999,  54 mmcfpd in 2000, 52 mmcfpd in 2001 and 52 mmcfpd
     in  2002.   Northrock  also  has  various   fixed-price   and   fixed-price
     differential  natural gas purchase  contracts  outstanding at September 30,
     1999, which require the purchase of 63 mmcfpd for the remainder of 1999 and
     23 mmcfpd in 2000.  The  company's  pre-tax  share of estimated  unrealized
     losses for these contracts was  approximately  $13 million at September 30,
     1999,  (net of minority  interests) and primarily  relate to contracts with
     delivery dates scheduled for the years 2001 through 2002.

     At September 30, 1999, the company had futures  contracts  outstanding with
     several  couterparties to purchase and sell approximately 19 million and 15
     million  barrels  of crude  oil,  respectively.  The fair  values  of these
     contracts,  based on quoted market prices, were approximately $104 million.
     The company also had futures contracts outstanding at September 30, 1999 to
     purchase and sell  approximately  19 million and 18 million  thousand cubic
     feet  (mcf)  of  natural  gas,  respectively.  The  fair  values  of  these
     contracts,  based on quoted market prices,  were  approximately $3 million.
     These contracts which were purchased as part of the company's  overall risk
     management  strategy were marked to market.  Approximately 2 percent of the
     company's  outstanding  crude oil and natural gas  futures  contracts  were
     related to the company's non-trading activities. At September 30, 1999, the
     company's  share of pre-tax  unrealized  gains  related to its  non-trading
     futures contract activity was approximately $2 million.

     The company had various hydrocarbon option contracts (options)  outstanding
     with several counterparties at September 30, 1999. Generally,  options have
     been  used to limit the  company's  exposure  to  adverse  commodity  price
     fluctuations.  In some cases,  the instruments may also limit the company's
     ability  to  participate   fully  in  future  gains  from  favorable  price
     movements.  These options are generally accounted for as hedges, with gains
     and losses  deferred and recognized as a component of crude oil and natural
     gas revenues upon the sale of the underlying production.

     At September 30, 1999, the company had  outstanding  purchased  natural gas
     options covering  approximately 31 million mcf and sold natural gas options
     covering  approximately  73 million mcf.  The options  consisted of put and
     call  contracts  that related to the company's  remaining  1999 US lower 48
     production,  to the future production of the company's Northrock subsidiary
     for the  remainder  of 1999  through  the year 2004,  and to the  company's
     overall risk management  activities.  At September 30, 1999, the fair value
     of these options were  approximately  $(6) million.  The fair values of the
     options were determined by dealer quotes, where available,  or by financial
     modeling  using  underlying  commodity  prices.  Net premiums  paid for the
     options  totaled $1 million.  Approximately  90 percent of the options were
     related to the company's non-trading activities. At September 30, 1999, the
     company's share (net of minority  interests) of pre-tax  unrealized  losses
     related to its non-trading  natural gas option  activity was  approximately
     $14  million.  Approximately  $6 million of the $14 million  relates to the
     company's interest in Northrock.

     The  company had  purchased  crude oil options  covering  approximately  43
     million  barrels  and sold  crude oil  options  covering  approximately  73
     million barrels outstanding at September 30, 1999. The options consisted of
     put and call  contracts  that related to the company's  remaining  1999 and
     early  2000  production,  to  the  production  of the  company's  Northrock
     subsidiary  for the  remainder  of 1999  through  the year  2002 and to the
     company's overall risk management activities.  At September 30, 1999, these
     options had fair values of approximately $(18) million.  The fair values of
     the  options  were  determined  by dealer  quotes  where  available,  or by
     financial modeling using underlying commodity prices. Net premiums paid for
     the  options  totaled $2 million.  Approximately  70 percent of the options
     were related to the  company's  non-trading  activities.  At September  30,
     1999, the company's share (net of minority interests) of pre-tax unrealized
     losses  related  to  its   non-trading   crude  oil  option   activity  was
     approximately  $21  million.  Approximately  $3 million of the $21  million
     relates to the company's interest in Northrock.

     At September  30, 1999,  the company had a ten-year  natural gas price swap
     agreement  outstanding.  The agreement effectively refloats the fixed price
     the company  received in January  1999 for a ten-year  natural gas pre-paid
     forward  sale.  As  the   counterparty  to  the  swap  agreement  remits  a
     current-index-price payment amount to the company based upon volumes in the
     swap  agreement,  the company  remits a fixed-price  payment  amount to the
     counterparty.  The pre-tax  deferred gain related to the swap  agreement at
     September 30, 1999, was approximately $16 million. This gain is offset by a
     corresponding loss on the fixed price physical sales contract.

     The company's Global Trade segment recorded pre-tax losses of approximately
     $10 million and $5 million on its trading  activities for the third quarter
     and first nine months of 1999, respectively.

(10) Accrued Abandonment, Restoration and Environmental Liabilities

     At  September  30,  1999,  the  company had  accrued  $464  million for the
     estimated   future  costs  to  abandon  and  remove  wells  and  production
     facilities.  The total costs for abandonments are predominantly accrued for
     on a  unit-of-production  basis and are estimated to be approximately  $655
     million.  This  estimate  was derived in large part from  abandonment  cost
     studies  performed by outside  firms and is used to calculate the amount to
     be  amortized.   The  company's  reserve  for   environmental   remediation
     obligations  at  September  30, 1999 totaled  $247  million,  of which $145
     million was included in current liabilities.

(11) Contingent Liabilities

          The  company  has  certain  contingent  liabilities  with  respect  to
          material existing or potential claims, lawsuits and other proceedings,
          including  those  involving  environmental,  tax  and  other  matters,
          certain of which are discussed more  specifically  below.  The company
          accrues  liabilities  when it is probable  that  future  costs will be
          incurred and such costs can be reasonably estimated. Such accruals are
          based on developments to date, the company's estimates of the outcomes
          of these matters and its  experience  in  contesting,  litigating  and
          settling other matters. As the scope of the liabilities becomes better
          defined, there will be changes in the estimates of

                                       8

(UNAUDITED)

     future costs, which could have a material effect on the company's future
     results of operations and financial condition or liquidity.

     Environmental  matters  - The  company  is  subject  to loss  contingencies
     pursuant to federal,  state and local  environmental  laws and regulations.
     These include  existing and possible future  obligations to investigate the
     effects of the  release or  disposal  of certain  petroleum,  chemical  and
     mineral  substances at various sites;  to remediate or restore these sites;
     to  compensate  others for damage to property  and natural  resources,  for
     remediation and  restoration  costs and for personal  injuries;  and to pay
     civil  penalties  and,  in some  cases,  criminal  penalties  and  punitive
     damages.  These obligations  relate to sites owned by the company or others
     andare  associated  with past and present  operations,  including  sites at
     which the company has been  identified as a potentially  responsible  party
     (PRP)  under  the  federal   Superfund  laws  and  comparable  state  laws.
     Liabilities  are  accrued  when it is probable  that  future  costs will be
     incurred and such costs can be reasonably estimated.

     However,  in many  cases,  investigations  are not yet at a stage where the
     company is able to determine  whether it is liable or, even if liability is
     determined to be probable, to quantify the liability or estimate a range of
     possible exposure.  In such cases, the amounts of the company's liabilities
     are  indeterminate due to the potentially large number of claimants for any
     given site or exposure,  the unknown  magnitude of possible  contamination,
     the  imprecise and  conflicting  engineering  evaluations  and estimates of
     proper  clean-up  methods and costs,  the unknown  timing and extent of the
     corrective actions that may be required,  the uncertainty  attendant to the
     possible award of punitive damages,  the recent judicial recognition of new
     causes of action,  the present state of the law,  which often imposes joint
     and several and retroactive  liabilities on PRPs, the fact that the company
     is usually just one of a number of companies  identified as a PRP, or other
     reasons.

     As  disclosed in note 10, at  September  30, 1999,  the company had accrued
     $247 million for estimated future environmental  assessment and remediation
     costs at various sites where  liabilities  for such costs are probable.  At
     those sites where  investigations  or feasibility  studies have advanced to
     the stage of  analyzing  feasible  alternative  remedies  and/or  ranges of
     costs,  the  company  estimates  that it could  incur  possible  additional
     remediation costs aggregating approximately $195 million.

     Tax  matters - The  company  believes  it has  adequately  provided  in its
     accounts for tax items and issues not yet resolved.

     Other  matters - In  February  1996,  Bridas  Corporation  filed a petition
     against the company and others in the  District  Court of Fort Bend County,
     Texas,  alleging  that  the  defendants  conspired  to and  did  tortiously
     interfere  with Bridas'  rights under  agreements  with the  government  of
     Turkmenistan  to develop the Yashlar  Field and to transport  gas from that
     field to Pakistan. The petition also alleged that the defendants interfered
     with Bridas'  exclusive right to lay a gas pipeline in Afghanistan.  Bridas
     sought actual damages, as well as punitive damages, plus interest.  Bridas'
     expert  witnesses  stated in pre-trial  discovery that Bridas' total actual
     damages for loss of future profits were approximately $1.7 billion.  In the
     alternative,  Bridas was  expected to seek an award of  approximately  $430
     million with respect to its total expenditures in Turkmenistan.  In October
     1998, the court granted the  defendants'  motion for summary  judgement and
     dismissed the action. In March 1999, Bridas filed a notice of appeal of the
     dismissal.

     In May 1999, a Canadian subsidiary of the company acquired an approximately
     46 percent  controlling  interest in Northrock  Resources Ltd.  (Northrock)
     (see note 13). Northrock has the right, until December 31, 1999, to require
     that the company purchase additional  Northrock common shares from treasury
     shares at a price of C$15 per  share,  up to a maximum  ownership  level of
     49.9 percent.

     In 1998,  the company  signed a letter  agreement  regarding the Transocean
     Discoverer  Spirit  deepwater  drill ship with a minimum daily rate of $210
     thousand for five years.  The drill ship is  scheduled  for delivery in the
     Gulf of Mexico in 2000.

     The company also has certain other  contingent  liabilities with respect to
     litigation,  claims,  and  contractual  agreements  arising in the ordinary
     course of business.  Although these  contingencies could result in expenses
     or judgments that could be material to the company's  results of operations
     for a given reporting  period, on the basis of management's best assessment
     of the  ultimate  amount  and  timing of these  events,  such  expenses  or
     judgments  are  not  expected  to have a  material  adverse  effect  on the
     company's consolidated financial condition or liquidity.

(13) Acquisition of Assets

     In May 1999, a Canadian  subsidiary of the company  acquired an approximate
     46-percent controlling interest in Northrock Resources Ltd. (Northrock),  a
     Canadian oil and gas exploration and production company,  for approximately
     $184  million.  The  acquisition  was  accounted  for  as a  purchase.  The
     investment  was  effected  by  the  acquisition  of 10  million  shares  of
     Northrock common stock at C$14 per share pursuant to a partial tender offer
     to Northrock's  shareholders  and 7.64 million  shares of Northrock  common
     stock at C$16 per share pursuant to a private placement. The acquisition is
     part  of  the  company's  overall  North  American  natural  gas  strategy.
     Northrock is fully  consolidated in the company's  financial  results as of
     the acquisition date.

(14) Minority Interests

     In April  1999,  the company  contributed  fixed-price  overriding  royalty
     interests from its working interest shares in certain oil and gas producing
     properties  in the Gulf of  Mexico to Spirit  Energy 76  Development,  L.P.
     (Spirit LP), a limited partnership.  In exchange for its overriding royalty
     contributions,  valued at $304  million,  the  company  received an initial
     general  partnership  interest of approximately 55 percent in Spirit LP. An
     unaffiliated  investor  contributed $250 million in cash to the partnership
     in exchange for an initial limited partnership interest of approximately 45
     percent.  Minority interests increased by approximately $244 million at the
     close  of this  transaction.  The  fixed-price  overrides  are  subject  to
     economic  limitations of production from the affected  fields.  The limited
     partner is  entitled to receive a priority  allocation  of profits and cash
     distributions.  The  partnership  has a maximum  term of 20 years,  but may
     terminate after six years, subject to certain conditions.

(UNAUDITED)

     As discussed in note 13, in May 1999, a Canadian  subsidiary of the company
     acquired an  approximate  46-percent of  Northrock.  The net result of this
     transaction  was to  increase  minority  interests  by  approximately  $145
     million as of the acquisition date.

(15) Restructuring Costs

     The company adopted a restructuring  plan during the second quarter of 1999
     that resulted in the accrual of a $18 million pre-tax restructuring charge.
     This amount included the costs of terminating  approximately 250 employees.
     The charge was included in selling,  administrative  and general expense on
     the  consolidated  earnings  statement.  The plan  involves the blending of
     several International and Geothermal organizations, a manpower optimization
     program  in  Thailand,  cost  cutting  and  efficiency  initiatives  in the
     company's  Diversified  Business and Exploration and Production  Technology
     groups and a company-wide shared resources initiative.

     Approximately  100  of the  affected  employees  were  from  the  company's
     International  operations,  95 were from the Diversified Business group and
     55  were  from  other   organizations,   including   corporate  staff.  The
     restructuring  charge  included  approximately  $16 million for termination
     costs to be paid to the employees over time and about $2 million related to
     outplacement and other costs.

     At October 26, 1999,  207  employees  had been  terminated  or had received
     termination notices as the result of the plan with additional  terminations
     scheduled during the remainder of 1999 and early 2000.

     In the fourth quarter of 1998,  the company  adopted a  restructuring  plan
     that resulted in the accrual of a $27 million pre-tax restructuring charge.
     This amount included the costs of terminating  approximately 475 employees.
     The charge was included in selling,  administrative  and general expense on
     the consolidated  earnings  statement.  The plan involves the suspension of
     mining  and  manufacturing  operations  at the  Mountain  Pass,  California
     lanthanide  facility,  a change in mining  operations  at the  Questa,  New
     Mexico molybdenum facility, the withdrawal from non-strategic activities in
     Central Asia and a reduction in activities of various business units.

     Approximately 240 of the affected  employees were from the company's mining
     operations,  95 were from various exploration and production business units
     and 140 were support  personnel  at various  locations.  The  restructuring
     charge included  approximately $23 million for termination costs to be paid
     to the employees  over time,  about $2 million in benefit plan  curtailment
     costs and about $2 million related to outplacement and other costs.

     At October 26, 1999,  414  employees  had been  terminated  or had received
     termination  notices as a result of the plan, with additional  terminations
     scheduled during the remainder of 1999 and early 2000.

     The amount of unpaid benefits  remaining on the consolidated  balance sheet
     at September 30, 1999 was $20 million for the two plans combined.

</TABLE>
Adjusted  after-tax  earnings increased $38 million in the third quarter of 1999
compared  with the same  period  last  year.  The  third  quarter  1999  results
benefited from higher worldwide average crude oil prices,  which increased by 44
percent from the third quarter of 1998.  In addition,  the third quarter of 1999
benefited from lower dry hole costs and a lower effective tax rate primarily due
to a change in the Thailand  foreign exchange rate. These factors were partially
offset by lower  crude oil and natural  gas sales  volumes and reduced  earnings
from  non-exploration and production  businesses.  In the third quarter of 1999,
the hedge program lowered sale realizations for crude oil and natural gas by $23
million after-tax.

Adjusted  after-tax  earnings  decreased $57 million in the first nine months of
1999 compared with the first nine months of 1998. The major factors contributing
to the decrease were lower  worldwide  crude oil and natural gas sales  volumes,
lower natural gas prices, lower agricultural  products prices,  reduced earnings
from other  non-exploration  and production  businesses and higher corporate net
interest expense.  These factors were partially offset by higher worldwide crude
oil prices, a lower effective tax rate primarily due to a change in the Thailand
foreign  exchange  rate and lower dry hole  costs.  For the first nine months of
1999, the hedge program lowered sale  realizations for crude oil and natural gas
by $16 million after-tax.

EXPLORATION AND PRODUCTION

The company  engages in oil and gas  exploration,  development,  and  production
worldwide.

United States - Included in the United States  category are Spirit Energy 76 and
Alaska oil and gas operations. The Spirit Energy 76 business unit is responsible
for oil and gas  operations  in the Lower 48 United  States with emphasis on the
shelf and  deepwater  areas in the Gulf of Mexico and the Permian  Basin in West
Texas.  A  substantial  portion of the crude oil and natural gas produced in the
United States is sold to the company's  Global Trade  segment.  The remainder is
sold to third parties or, in the case of Alaska natural gas production,  used in
the company's agricultural products operations.

</TABLE>
Adjusted  after-tax  earnings increased $32 million in the third quarter of 1999
compared  with the same period last year.  The  increase  was  primarily  due to
higher United States average crude oil and natural gas prices,  which  increased
by $5.66 per barrel and $0.25 per MCF,  respectively.  In addition to the higher
prices,  dry hole costs were lower than the same period last year. These factors
were partially offset by lower United States natural gas sales volumes and lower
Spirit  Energy 76 crude oil sales  volumes.  In the third  quarter of 1999,  the
hedge  program  lowered sale  realizations  for crude oil and natural gas by $17
million after-tax.

Adjusted  after-tax  earnings  increased $10 million in the first nine months of
1999 compared with the first nine months of 1998. The increase was primarily due
to higher  United  States  crude  oil  prices,  lower  dry hole  costs and lower
operating  expenses.  These factors were partially offset by lower United States
crude oil and natural gas sales volumes, increased exploratory land amortization
and lower  Alaska  natural  gas prices.  For the first nine months of 1999,  the
hedge  program  lowered sale  realizations  for crude oil and natural gas by $10
million after-tax.

International - Includes the company's international  exploration and production
activities and related business development  activities.  The company is engaged
in oil and gas  production  activities  in eight  foreign  countries:  Thailand,
Indonesia, Canada, The Netherlands, Azerbaijan, Myanmar, the Democratic Republic
of Congo and Bangladesh.

</TABLE>
Adjusted  after-tax  earnings increased $46 million in the third quarter of 1999
compared  with the same period last year.  The  increase  was  primarily  due to
higher average crude oil prices,  lower dry hole costs,  lower  exploration  and
operating expenses,  and a lower effective tax rate primarily due to a change in
the Thailand  foreign  exchange rate.  Partially  offsetting  these factors were
lower Far East  crude oil  sales  volumes,  primarily  in  Indonesia,  and lower
International natural gas prices.

Adjusted  after-tax  earnings  increased $42 million in the first nine months of
1999 compared with the first nine months of 1998. The major factors contributing
to the increase were higher  average  crude oil prices,  lower  exploration  and
operating  expenses,  lower dry hole costs,  lower  depreciation,  depletion and
amortization  expense,  and a lower effective tax rate primarily due to a change
in the Thailand  foreign  exchange rate.  These factors were partially offset by
lower crude oil sales volumes,  primarily in Indonesia,  and lower international
natural gas prices.

Adjusted  after-tax  earnings  decreased $9 million in the third quarter of 1999
compared with the same period last year. The decrease was primarily due to lower
margins on domestic natural gas trading.

Adjusted  after-tax  earnings decreased $14 million for the first nine months of
1999 compared with the same period last year.  The decrease was primarily due to
lower margins on domestic natural gas and crude oil trading.

</TABLE>
Adjusted  after-tax  earnings decreased $10 million in the third quarter of 1999
compared  with the same  period  last year.  Lower  affiliate  earnings,  higher
foreign  exchange  losses in Indonesia and the loss of earnings from The Geysers
assets in Northern  California  contributed to the lower results.  These factors
were partially offset by lower Indonesia receivable provisions.

Adjusted  after-tax  earnings  decreased $13 million in the first nine months of
1999  compared  with the first nine months of 1998.  This decrease was primarily
due to the  difference  in the  recognition  of  cash  received  related  to the
construction  of the Salak  power  plant  units 4  through  6,  lower  affiliate
earnings  and  the  loss  of  earnings  from  The  Geysers  assets  in  Northern
California.  These factors were partially  offset by lower Indonesia  receivable
provisions.

</TABLE>
Adjusted  after-tax  earnings  decreased $9 million in the third quarter of 1999
compared with the same period last year. The decrease was primarily due to lower
agricultural  products  prices and lower tax  benefits,  the effect of which was
partially offset by decreased mining costs and increased affiliate earnings.

Adjusted  after-tax  earnings  decreased $30 million in the first nine months of
1999  compared  with the first nine months of 1998.  This decrease was primarily
due to lower agricultural products prices.

addition,  the third  quarter of 1999 had higher  interest  expense due to lower
capitalized interest and increased debt levels.

The adjusted after-tax loss increased by $52 million in the first nine months of
1999  compared  with the same period last year.  The negative  factors  included
higher interest expense due to lower capitalized interest and increased

debt levels, lower pension income and higher employee benefit-related  expenses,
both in the Other category. The first nine months of 1998 included a net benefit
related to certain tax  adjustments  and higher  earnings and  dividends  from a
petroleum industry mutual insurance company,  both in the Other category.  Those
factors  were  partially  offset by lower new  ventures  expenditures  and gains
related to miscellaneous asset sales, in the Other category.

FINANCIAL CONDITION AND CAPITAL EXPENDITURES

For the  first  nine  months  of  1999,  net cash  flow  provided  by  operating
activities was $517 million compared with $711 million in the same period a year
ago. This decrease reflects the effects of lower worldwide crude oil and natural
gas sales volumes,  lower natural gas prices, lower agricultural products prices
and reduced earnings from other non-exploration and production businesses. These
factors were  partially  offset by higher  worldwide  crude oil prices.  Working
capital and other changes  included the effects of increased net foreign  income
tax  payments  over  refunds,  the  delivery of crude oil under a 1998  pre-paid
forward sale and increased  inventories.  Working capital changes benefited from
the receipt of $120 million in the first quarter of 1999 for a ten-year  natural
gas  pre-paid  forward  sale and the  advance  sale of  certain  domestic  trade
receivables in the third quarter of 1999.

Proceeds  from asset sales for the first nine months of 1999 were $163  million,
consisting  primarily of $101 million from the sale of the company's interest in
a geothermal operation at The Geysers in Northern  California,  completed in the
first quarter,  $27 million from the sale of Michigan oil and gas assets and $35
million  from  the  sale of other  miscellaneous  domestic  oil and gas and real
estate properties.

Capital  expenditures  for the first nine months of 1999  totaled  $761  million
compared  with $1,248  million in the same period a year ago.  The  decrease was
primarily  due  to  lower   worldwide   drilling   activities  and  lower  lease
acquisitions  in the Gulf of Mexico.  The company also spent $184 million in the
second quarter of 1999 to acquire an approximate  46-percent  ownership interest
in Northrock Resources Ltd. (Northrock). Total capital expenditures are expected
to be approximately $1.17 billion for 1999, excluding the Northrock acquisition.
The  company  will  continue  to  focus on  deepwater  exploration  programs  in
Indonesia and the Gulf of Mexico.

In the second quarter of 1999, the company  contributed  fixed-price  overriding
royalty  interests  from its  working  interest  shares in  certain  oil and gas
producing properties in the Gulf of Mexico to Spirit Energy 76 Development, L.P.
(Spirit LP), a limited  partnership.  The  fixed-price  overrides are subject to
economic limitations of production from the affected fields. In exchange for its
overriding royalty  contributions,  valued at $304 million, the company received
an initial general  partnership  interest of  approximately 55 percent in Spirit
LP. An unaffiliated investor contributed $250 million in cash to the partnership
in exchange for an initial  limited  partnership  interest of  approximately  45
percent.  The limited  partner is entitled to receive a priority  allocation  of
profits and cash distributions.

The company's  long-term debt was $2.83 billion at September 30, 1999,  compared
with  $2.56  billion  at  year-end  1998.  Most of this  increase  reflects  the
consolidation   of  the  company's   investment  in  Northrock,   including  its
outstanding  debt.  The  company's  debt-to-total  capitalization  ratio  was 52
percent at September 30, 1999, compared with 48 percent at year-end 1998.

ENVIRONMENTAL MATTERS

At September 30, 1999,  the  company's  reserves for  environmental  remediation
obligations  totaled $247 million, of which $145 million was included in current
liabilities. During the third quarter of 1999, cash payments of $30 million were
applied  against the reserve.  The company also estimates that it possibly could
incur additional  remediation costs aggregating  approximately $195 million,  as
discussed in note 11 to the  consolidated  financial  statements.  The company's
total   environmental   reserve  amount  is  grouped  into  the  following  five

OUTLOOK

Certain of the statements in this discussion,  as well as other  forward-looking
statements within this document, contain estimates and projections of amounts of
or  increases / decreases  in future  revenues,  earnings,  cash flows,  capital
expenditures, assets, liabilities and other financial items and of future levels
of or increases / decreases in reserves,  production,  sales  including  related
costs  and  prices,  and  other  statistical  items;  plans  and  objectives  of
management regarding the company's future operations, products and services; and
certain assumptions underlying such estimates,  projection plans and objectives.
While these forward-looking statements are made in good faith, future operating,
market,  competitive,  legal,  economic,  political,  environmental,  and  other
conditions and events could cause actual results to differ materially from those
in the foward-looking statements. See pages 40 and 41 of Management's Discussion
and Analysis in Item 7 of the  company's  1998 Annual  Report on Form 10-K for a
discussion of certain of such conditions and events, as well as pages 24 through
26 of this report.

The company's Spirit Energy 76 (Spirit)  business unit averaged 729 MMCF per day
of net  natural  gas  production  in the  third  quarter  of 1999.  The  company
estimates  that,  because of the  current  drilling  activity  and the return to
production of key wells after repairs,  Spirit's net natural gas production will
average approximately 750 MMCF per day in the fourth quarter of 1999.

The company drilled a deepwater well in the Sumatra sub-salt  prospect in Garden
Banks block 941 in the Gulf of Mexico during the third quarter of 1999. The well
encountered  mechanical  difficulties  before reaching its primary objective and
has been suspended until next year, when the larger  Discoverer Spirit drillship
will be delivered and drilling will be resumed.  During the third  quarter,  oil
was discovered on the K-2 deepwater  well, on Green Canyon block 562 in the Gulf
of  Mexico,  in  which  the  company  was  participating.   The  joint  interest
participants  decided to  temporarily  suspend  the well and  develop  plans for
appraisal of the hydrocarbon zone. The company was drilling an appraisal well of
the  McKinley  discovery  on  Garden  Banks  block  416 at the end of the  third
quarter.  The company is  participating  in the drilling of an appraisal well on
the Mad Dog discovery  which began at the end of the third quarter.  The company
is currently  evaluating  the Mirage  discovery  and no  additional  drilling is
expected this year.

During the third quarter of 1999, the company was the apparent  successful  high
bidder for interests in 15 lease blocks in the western Gulf of Mexico, including
seven deepwater blocks and eight shelf blocks. The company has been awarded nine
out of the fifteen blocks with the remaining blocks yet to be awarded.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

The  economic  situation  in Asia,  where  much of the  company's  international
activity is centered, remained largely unchanged from year-end 1998. The company
believes that the  governments  in the region are committed to  undertaking  the
reforms and restructuring  necessary to enable their nations to recover from the
downturn.

In  Thailand,  net natural gas sales are expected to average  approximately  600
MMCF per day in the fourth  quarter of 1999,  as compared with an average of 643
MMCF per day for the third quarter of 1999.  Production from the Pailin field in
the Gulf of  Thailand  started  in  August  of 1999 and is  currently  producing
approximately  185 MMCF (gross) per day in the fourth quarter.  Unocal Thailand,
Ltd., is operator of the Pailin field and holds a 35 percent working interest.

In Myanmar, commercial production from the Yadana field is now expected to begin
very late in 1999 or in early 2000.

The company received  approvals from  Indonesia's  national oil company to begin
initial  development  activities  on the West Seno and  Merah  Besar oil and gas
fields in the deepwater Kutei Basin, offshore East Kalimantan.  Unocal Makassar,
Ltd., a wholly owned  subsidiary,  is operator of the West Seno discovery in the
Makassar  Strait  production-sharing  contract  (PSC) area and has a  50-percent
working  interest.  The Merah Besar field is located on the Makassar  Strait PSC
and the East Kalimantan PSC areas. Unocal Indonesia Company, also a wholly owned
subsidiary,  holds a 100-percent  working  interest in the East  Kalimantan PSC.
Development  activity is planned in two phases,  with phase one production  from
the West Seno field  expected in 2002.  With this  approval,  the two fields now
qualify  to supply gas for the latest  package of LNG sales and  natural  gas is
also  available  for  LPG  extraction.   In  November,   the  company  announced
discoveries  of oil and gas in the  Bangka and Aton  prospects  in the Rapak PSC
area which further confirm the hydrocarbon resource potential of the Kutei Basin
deepwater properties. The company has a 60-percent working interest in the Rapak
PSC.

The company completed,  in October,  an exchange of its interest in a subsidiary
holding a 28.57 percent stake in three  producing  fields in Yemen for the stock
of two Occidental Petroleum Corporation  subsidiaries holding 50-percent working
interests in three  blocks in northeast  Bangladesh.  These  Bangladesh  assets,
received by the company in July 1999,  include two production  sharing contracts
in which the company already held 50-percent working interests. In addition, the
assets  include  the  Bibiyana  gas  field,  discovered  in  1998.  The  company
transferred  to Occidental  Petroleum  Corporation  its working  interest in the
production-sharing  contract  of the East Shabwa  contract  area in Yemen in the
fourth quarter of 1999.

As of  September  30,  1999,  the  company  had a gross  receivable  balance  of
approximately  $158 million  related to its geothermal  operations in Indonesia.
Approximately $61 million related to Salak electric generating Units 1, 2, and 3
and is due by  November  27,  1999,  of which $53  million  represents  past due
amounts and accrued  interest  resulting  from  partial  payments for March 1998
through  July 1999.  Although  invoices  have  generally  not been paid in full,
amounts that have been paid have been  received in a timely manner per the steam
sales contract.  The remaining $97 million relates to Salak electric  generating
Units 4, 5 and 6 which the company has received  partial payments for the period
of March  1998  through  July  1999.  Provisions  covering  a  portion  of these
receivables  were recorded in 1998 and 1999. The company is vigorously  pursuing
collection of the outstanding receivables.

The company, at times, employs a commodity price option program that establishes
a price floor,  while retaining most of the benefits of higher price  movements.
This program is designed to protect cash flow and the capital  spending  program
against the effects of severe commodity price deterioration.  For the first nine
months of 1999,  the program  resulted in lower  realizations  for crude oil and
natural gas totaling about $16 million after-tax.  For the full-year 1999, based
on recent NYMEX oil and gas futures prices, the company anticipates this program
will lower  earnings by  approximately  $29 million  after-tax.  This  program's
results exclude hedging activities by Northrock.  In 1999,  Northrock's  hedging
activities are expected to lower the company's share of Northrock's  earnings by
approximately $3 million after-tax.  Most of the company's existing  non-trading
positions close out in the fourth quarter, with the exception of certain options
and fixed-price  contracts for Northrock which extend to the year 2004. For more
information, refer to note 9 to the consolidated financial statements.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

The company  adopted two separate  restructuring  plans in the second quarter of
1999 and the fourth  quarter  of  1998that  will  result in the  termination  of
approximately 250 and 475 employees,  respectively.  For more information, refer
to  note  15 to the  consolidated  financial  statements.  The  company  expects
implementation of the plans to reduce future annualized salaries and benefits by
an estimated $32 million after-tax.  Cash expenditures  related to the plans are
estimated  to be $19  million  and $8  million  for the  years  1999  and  2000,
respectively.

YEAR 2000

The company is essentially  complete in addressing the Year 2000 (Y2K) issue for
critical systems and applications.

Many  existing  computer  programs  were  designed and developed to use only two
digits to identify a year in the date field.  If not  addressed,  these programs
could result in system  failures with possible  material  adverse effects on the
company's operations at the beginning of the year 2000.

The company's Y2K efforts are divided into three general categories: information
technology (IT) systems and  applications,  non-IT  embedded  systems in process
controls,  and its relationships  with critical business  partners.  The company
appointed  a program  manager  and  assembled  various  teams of  professionals,
principally at the business unit level, which developed plans to implement these
efforts.  The plans established a methodology and schedule to identify,  assess,
correct and test the company's IT systems, applications, non-IT embedded systems
(such as  microcontrollers  and other devices used for process control),  system
interfaces with vendors, suppliers, customers and other outside parties, as well
as to assess the Y2K  readiness of such third  parties.  The company  contracted
with systems  consulting  firms to assist with the  assessment,  correction  and
testing  of the  company's  internal  systems  and their  interfaces  with third
parties.  To ensure  independent  review and validation of the implementation of
the company's Y2K plans, internal auditors,  assisted by contract auditors,  are
auditing the Y2K projects of key business units within the company and reporting
their findings to senior management.

A  company-wide  initial  awareness  campaign was  completed  in June 1998.  The
identification,  assessment, and planning phases of the internal systems portion
of the project have been completed.  The company has written and tested business
contingency and recovery plans for 99 percent of its "mission critical" systems,
applications and processes.  These systems,  applications and processes,  if not
operable, could materially adversely impact cash flow, operations, safety or the
environment.

The  company's  Y2K project  work  includes the writing and updating of existing
contingency  plans to address  material  Y2K issues.  The  company has  existing
processes  for  managing  emergency  situations  and  intends to have its Crisis
Management  Center  operating at the time of the century rollover to assist with
implementing any contingency plans if required.

The company has  completed  the  inventory  and  assessment of its IT and non-IT
embedded systems and detailed planning to correct or work around the anticipated
problems in these systems. The  remediation/renovation and validation/testing of
its IT and non-IT embedded systems were  approximately 98 percent complete as of
September 30, 1999.

<PAGE>
ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

The  following  schedule  sets  forth  the  company's  estimated  timetable  for
achieving Y2K readiness of its IT and embedded systems:
<TABLE>
<CAPTION>
Project Phases                                      Target Completion Dates

Worldwide assessment                                Completed
Initial plan for corrections/work arounds           Completed
Remediation/renovation                              98% Completed; Finish fourth quarter 1999
Contingency planning                                99% Completed; Finish fourth quarter 1999
Validation/testing                                  98% Completed; Finish fourth quarter 1999
Implementation                                      98% Completed; Finish fourth quarter 1999
Continuous system review                            Ongoing-through first quarter 2000
</TABLE>
The company has identified  approximately 400 "critical business partners".  The
overall  assessment  of the  Year  2000  readiness  of these  partners  has been
positive. Work in this area will continue and contingency plans will incorporate
the possibility of performance failures by multiple critical business partners.

The  company  estimates  the  total  expenditures  on its  Y2K  project  will be
approximately $25 million.  These expenditures are recorded at the business unit
and corporate levels and are funded from cash provided by operating  activities.
Expenditures as of September 30, 1999, were  approximately $21 million.  Most of
the remaining expenditures are expected to be incurred in the remainder of 1999.

The  company is not aware of any IT projects  that have been  delayed due to the
Y2K project.

The Y2K  problem  is real and  there is a risk of Y2K  related  failures.  These
failures could result in an interruption  in, or a failure of, certain  business
activities or functions. Such failures could materially and adversely affect the
company's results of operations,  liquidity or financial  condition.  Due to the
uncertainty  surrounding  the Y2K problem,  including the uncertainty of the Y2K
readiness of the company's customers,  suppliers,  and partners,  the company is
unable at this time to  determine  the true impact of the Y2K problem to Unocal.
The  principal  areas of risk are thought to be oil and gas  production  control
systems,   other  embedded  operations  control  systems  and  third  party  Y2K
readiness. The company's Y2K project is expected to reduce this uncertainty. The
company  believes  that with the  completion  of the  project  as  planned,  the
possibility of significant interruptions of normal operations should be reduced.
There can be no  assurance,  however,  that such  changes will prove 100 percent
effective  in resolving  all Y2K related  issues.  Furthermore,  there can be no
assurance  that  critical  business  partners  will  not  experience   failures,
irrespective of the Y2K readiness  representations  they may have made. A likely
worst case  scenario  is that  despite  the  company's  efforts,  there could be
failures of control  systems,  which might cause some processes to be shut down.
Such failures could have a material adverse impact on the company's  operations.
The company is particularly  concerned about the status of key critical business
partners' Y2K readiness in Indonesia,  Bangladesh, Thailand and The Philippines.
Their failure due to a Year 2000 problem could  prevent  Unocal from  delivering
product and cause a material adverse impact to the company's cash flows.

Future Accounting Changes

In June 1999,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards  ("SFAS") No. 137,  which delayed the effective
date  of SFAS  No.  133  "Accounting  for  Derivative  Instruments  and  Hedging
Activities".  SFAS No. 133 required that companies  recognize all derivatives as
either assets or liabilities in the statement of financial  position and measure
those instruments at fair value. The accounting for changes in the fair value of
a derivative  instrument depends upon the intended use of the instrument and its
resulting  designation.  Unless designated as a hedge, changes in the fair value
of a derivative  instrument  are to be  accounted  for as gains or losses in the
period of change. In the case of certain hedging activities, changes in the fair
values of derivative  instruments that are effective as hedges, are deferred and
reported  as part of other  comprehensive  income.

<PAGE>
ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

Changes in the fair value of  derivative  instruments  that are not effective as
hedges are reported in earnings in the period of the change.

SFAS No.  133 had  required  companies  to adopt its  provisions  for all fiscal
quarters of fiscal  years  beginning  after June 15,  2000.  SFAS 137 delays the
effective date to all fiscal  quarters of fiscal years  beginning after June 15,
2001. The company is planning to adopt SFAS 133 in the first quarter of the year
2001 and is  currently  evaluating  the  impact the  statement  will have on its
reporting for derivative instruments and hedging activities.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk generally represents the risk that losses may occur in the values of
financial  instruments  as a result of  movements  in  interest  rates,  foreign
currency  exchange  rates and  commodity  prices.  As part of its overall  risk-
management  strategies,  the company uses  derivative  financial  instruments to
manage and reduce risks associated with these factors.  The company also pursues
outright  pricing  positions  in  certain   hydrocarbon   derivative   financial
instruments, such as futures and options contracts.

Interest  Rate  Risk - From time to time the  company  temporarily  invests  its
excess  cash in  interest-bearing  securities  issued by  high-quality  issuers.
Company  policies  limit  the  amount of  investment  in  securities  of any one
financial institution. Due to the short time the investments are outstanding and
their general liquidity, these instruments are classified as cash equivalents in
the  consolidated  balance sheet and do not  represent a material  interest rate
risk to the company.  The company's primary market-risk  exposure for changes in
interest rates relates to the company's long-term debt obligations.  The company
manages its exposure to changing interest rates principally through the use of a
combination  of  fixed  and  floating-rate  debt.  Interest-rate  risk-sensitive
derivative  financial  instruments,  such as swaps,  options,  floors, caps, and
collars may also be used depending upon market conditions.

The company  evaluated the potential  effect that near-term  changes in interest
rates  would  have had on the fair  value  of its  interest-rate  risk-sensitive
financial  instruments at September 30, 1999. Assuming a ten-percent decrease in
the  company's  weighted  average  borrowing  costs at September  30, 1999,  the
potential  increase  in the fair value of the  company's  debt  obligations  and
associated derivative instruments,  including the company's net interests in the
debt  obligations  and associated  derivative  instruments of its  subsidiaries,
would have been approximately $118 million.

Foreign Exchange Rate Risk - The company  conducts  business in various parts of
the world and in various  foreign  currencies.  To limit the  company's  foreign
currency   exchange-rate  risk  related  to  operating  income,   foreign  sales
agreements generally contain price provisions designed to insulate the company's
sales  revenues  against  adverse  foreign-currency   exchange  rates.  In  most
countries,  energy  products  are valued and sold in U.S.  dollars  and  foreign
currency operating cost exposures have not been significant. In other countries,
the company is paid for product  deliveries  in local  currencies  but at prices
indexed to the U.S.  dollar.  These funds,  less amounts  retained for operating
costs,  are  converted to U.S.  dollars as soon as  practicable.  The  company's
Canadian subsidiaries are paid in Canadian dollars for crude oil and natural gas
sales.  Excess  Canadian  funds  generally  have been  invested in other  Unocal
foreign operations.

From time to time the company  may  purchase  foreign-currency  options or enter
into  foreign-currency  forward  contracts to limit the exposure  related to its
foreign-currency  obligations.  At September 30, 1999, the company evaluated the
effect that near term  changes in  foreign-exchange  rates would have had on the
fair value of the company's foreign-currency position related to its outstanding
foreign-currency forward contracts. Assuming an adverse change of ten percent in
foreign-currency exchange rates at September 30, 1999, the potential decrease in
fair value of the company's  foreign-currency  forward contracts,  including the
company's  net  interests  in  the  foreign-currency  forward  contracts  of its
subsidiaries, would have been approximately $13 million.

                                       26
<PAGE>
ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK (CONTINUED)

Commodity Price Risk - The company is a producer, purchaser, marketer and trader
of certain hydrocarbon commodities such as crude oil and condensate, natural gas
and  petroleum-based  products and is subject to the associated price risks. The
company  uses  hydrocarbon  derivative  financial  instruments,  such as futures
contracts,  swaps and options generally with maturities of 24 months or less, to
mitigate  its  exposure  to  commodity  price   fluctuations.   However,   these
instruments  may also limit some of the future gains  otherwise  available  from
favorable commodity price movements.

When these  instruments are used to hedge the company's future  production,  the
impacts are reflected in the average sales prices of the associated  commodities
at the time of sale. As a result,  the company's  reported crude oil and natural
gas  revenues  may be higher or lower than what would have been  reported if the
company had not employed the use of these  instruments.  From time to time,  the
company  also  enters  into  longer-term  derivative  instruments,  such as swap
contracts,  to refloat its long term fixed-price  commitments.  The company also
takes  pricing  positions  in  hydrocarbon   derivative  financial   instruments
(primarily futures and options contracts).

The company uses a variance-covariance  value-at-risk model to assess the market
risk of its  hydrocarbon-price-sensitive  derivative instruments.  Value-at-risk
represents the potential loss in fair value the company would  experience on its
hydrocarbon-price-sensitive    derivative    instruments,    using    calculated
volatilities  and  correlations  over a  specified  time  period  with  a  given
confidence  level.  The company's model is based upon historical data and uses a
three-day time interval with a 95-percent  confidence  level. The model includes
offsetting   physical  positions  for   hydrocarbon-price-sensitive   derivative
instruments  related to the company's pre-paid crude oil and natural gas forward
sales,  as well the company's net interests in its  subsidiaries'  crude oil and
natural gas derivative  instruments  including  offsetting physical positions of
forward  sales  contracts  to  which  those  contracts  relate.  Based  upon the
company's  model,  the  value  at risk  related  to  hydrocarbon-price-sensitive
derivative  financial  instruments  held for  purposes  other than  trading  was
approximately  $7 million at September  30 (refer to note 9 to the  consolidated
financial  statements  for  information  on  pre-tax  unrealized  losses  as  of
September 30, 1999 relating to hydrocarbon  price-sensitive derivative financial
instruments held for purposes other than trading).  The value at risk related to
hydrocarbon-price-sensitive  derivative  financial  instruments held for trading
purposes was approximately $1 million at September 30, 1999.

                      RESTATED CERTIFICATE OF INCORPORATION
                                       OF
                               UNOCAL CORPORATION
                   (Originally incorporated on March 18, 1983)


     FIRST: The name of this corporation is:

                               UNOCAL CORPORATION

     SECOND: The name and address of the registered agent of the corporation in
the State of Delaware is:

                          The Corporation Trust Company
                            Corporation Trust Center
                               1209 Orange Street
                  Wilmington, New Castle County, Delaware 19801

     THIRD:  The  purpose of the  corporation  is to engage in any lawful act or
activity for which  corporations may be organized under the General  Corporation
Law of Delaware.

     FOURTH:  The total  number of shares of stock which the  corporation  shall
have  authority to issue is eight hundred fifty  million  (850,000,000)  shares,
consisting of seven hundred fifty million  (750,000,000) shares of Common Stock,
having a par value of $1.00 per share,  and one  hundred  million  (100,000,000)
shares of Preferred  Stock,  having a par value of $0.10 per share. The board of
directors  is  authorized,  subject to any  limitations  prescribed  by law,  to
provide for the issuance of the shares of Preferred Stock in one of more series,
and by  filing a  certificate  pursuant  to the  applicable  law of the State of
Delaware,  to establish from time to time the number of shares to be included in
each such series, and to fix the designation, powers, preferences, and rights of
the  shares  of  each  such  series  and  any  qualifications,   limitations  or
restrictions  thereof. The number of authorized shares of Preferred Stock may be
increased  or  decreased  (but not below  the  number  of  shares  thereof  then
outstanding) by the affirmative  vote of the holders of a majority of the Common
Stock,  without a vote of the holders of the Preferred  Stock,  or of any series
thereof,  unless  a  vote  of any  such  holders  is  required  pursuant  to the
certificate or certificates establishing the series of Preferred Stock.

Pursuant to the  authority  vested in the board of  directors  by the  preceding
paragraph of this Article  FOURTH,  the following  series of Preferred Stock has
been created,  and the  designation  and amount  thereof and the voting  powers,
preferences  and relative,  participating,  optional and other special rights of
the shares of such series, and the  qualifications,  limitations or restrictions
thereof are as set forth in the exhibit  attached  hereto as specified below and
incorporated herein by reference:

     Exhibit I Series A Junior Participating Cumulative Preferred Stock

     FIFTH:  New bylaws may be adopted or the bylaws may be amended or  repealed
by a vote of seventy-five  percent of the  outstanding  stock of the corporation
entitled to vote thereon. Bylaws may also be adopted, amended or repealed by the
Board of Directors as provided or permitted by law; however, any bylaw amendment
adopted by the Board of Directors  increasing or reducing the authorized  number
of directors shall require a resolution  adopted by the affirmative  vote of not
less than seventy-five percent of the directors.

     SIXTH:  The number of directors  which shall  constitute the whole Board of
Directors  of  the  corporation  shall  be as  specified  in the  bylaws  of the
corporation,  subject to the provisions of Article FIFTH hereof and this Article
SIXTH. The board is divided into three classes, Class I, Class II and Class III.
Such classes  shall be as nearly equal in number of directors as possible.  Each
director shall serve for a term ending on the third annual meeting following the
annual meeting at which such director was elected;  provided,  however, that the
directors  first  elected to Class I shall serve for a term ending on the annual
meeting next  following the end of the calendar year 1983,  the directors  first
elected to Class II shall serve for a term ending on the second  annual  meeting
next  following  the end of the  calendar  year 1983,  and the  directors  first
elected to Class III shall serve for a term ending on the third  annual  meeting
next following the

<PAGE>
end of the calendar  year 1983.  The  foregoing  notwithstanding,  each director
shall  serve until his  successor  shall have been duly  elected and  qualified,
unless he shall  resign,  become  disqualified,  disabled or shall  otherwise be
removed.

     At each annual election,  the directors chosen to succeed those whose terms
then expire shall be of the same class as the directors they succeed, unless, by
reason of any  intervening  changes in the authorized  number of directors,  the
Board  shall  designate  one or more  directorships  whose term then  expires as
directorships  of another  class in order more  nearly to  achieve  equality  of
number of directors among the classes.

     Notwithstanding the rule that the three classes shall be as nearly equal in
number of directors as  possible,  in the event of any change in the  authorized
number  of  directors  each  director  then  continuing  to serve as such  shall
nevertheless  continue as a director of the class of which he is a member  until
the expiration of his current term, or his prior death,  resignation or removal.
If any newly created  directorship may,  consistent with the rule that the three
classes  shall be as  nearly  equal in  number  or  directors  as  possible,  be
allocated to one or two or more classes,  the Board shall allocate it to that of
the available classes whose term of office is due to expire at the earliest date
following such allocation.

     SEVENTH:  The affirmative vote of the holders of not less than seventy-five
percent of the outstanding  stock of the  corporation  entitled to vote shall be
required for approval if (1) this  corporation  merges or consolidates  with any
other  corporation if such other corporation and its affiliates singly or in the
aggregate  are directly or  indirectly  the  beneficial  owners of more than ten
percent (10%) of the total voting power of all outstanding  shares of the voting
stock of this corporation  (such other corporation being herein referred to as a
"Related  Corporation"),  or if (2) this corporation sells or exchanges all or a
substantial  part of its assets to or with such Related  Corporation,  or if (3)
this  corporation  issues or delivers any stock or other securities of its issue
in exchange or payment for any properties or assets of such Related  Corporation
or  securities  issued  by  such  Related  Corporation,  or in a  merger  of any
affiliate of this  corporation  with or into such Related  Corporation or any of
its  affiliates;  provided,  however,  that the foregoing shall not apply to any
such merger,  consolidation,  sale or exchange, or issuance or delivery of stock
or other  securities  which  was (i)  approved  by  resolution  of the  Board of
Directors adopted by the affirmative vote of not less than seventy-five  percent
of the directors  prior to the  acquisition of the beneficial  ownership of more
than ten percent  (10%) of the total voting power of all  outstanding  shares of
the  voting  stock  of the  corporation  by  such  Related  Corporation  and its
affiliates,  nor  shall it apply to any such  transaction  solely  between  this
corporation  and another  corporation  fifty percent (50%) or more of the voting
stock  of  which  is owned by this  corporation.  For the  purposes  hereof,  an
"affiliate" is any person (including a corporation,  partnership,  trust, estate
or individual) who directly,  or indirectly through one or more  intermediaries,
controls,  or is  controlled  by, or is under common  control  with,  the person
specified. "Control" means the possession,  directly or indirectly, of the power
to direct or cause the  direction  of the  management  and policies of a person,
whether through the ownership of voting securities,  by contract,  or otherwise;
and in computing the percentage of outstanding  voting stock  beneficially owned
by any person the shares outstanding and the shares owned shall be determined as
of the record  date fixed to  determine  the  stockholders  entitled  to vote or
express  consent with respect to such proposal.  The  stockholder  vote, if any,
required for mergers, consolidations,  sales or exchanges of assets or issuances
of stock or other securities not expressly  provided for in this Article,  shall
be such as may be  required  by  applicable  law.  A  "substantial  part" of the
corporation's  assets shall mean assets  comprising more than ten percent of the
book value of fair market value of the total assets of the  corporation  and its
subsidiaries taken as a whole.

     EIGHTH: No action shall be taken by the stockholders except at an annual or
special  meeting of  stockholders.  No action shall be taken by  stockholders by
written consent.

     NINTH:  Special  meetings of the  stockholders  of the  corporation for any
purpose or purposes may be called at any time by the Board of Directors, or by a
majority of the  members of the Board of  Directors,  or by a  committee  of the
Board of Directors  which has been duly designated by the Board of Directors and
whose  powers  and  authority,  as  provided  in a  resolution  of the  Board of
Directors or in the by-laws of the  corporation,  include the power to call such
meetings,  but such  special  meetings  may not be called by any other person or
persons; provided,  however, that, if and to the extent that any special meeting
of  stockholders  may be called by any other person or persons  specified in any
provisions of this Certificate of Incorporation or any amendment  thereto,  then
such special meeting may also be called by the person or persons, in the manner,
at the times and for the purposes so specified.

                                     2
<PAGE>
     TENTH: The corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation,  in the manner now
or hereafter  prescribed by statute,  and all rights  conferred on  stockholders
herein are granted subject to this reservation.  Notwithstanding  the foregoing,
the provisions set forth in Articles FIFTH, SIXTH,  SEVENTH,  EIGHTH,  NINTH and
this  Article  TENTH may not be  repealed or amended in  anyrespect  unless such
repeal or  amendment is approved by the  affirmative  vote of the holders of not
less than  seventy-five  percent of the total  voting  power of all  outstanding
shares of voting stock of this corporation.

     ELEVENTH:  A director of the corporation  shall not be personally liable to
the corporation or its shareholders for monetary damages for breach of fiduciary
duty as a director,  except for liability  (i) for any breach of the  director's
duty of  loyalty  to the  corporation  or its  shareholders,  (ii)  for  acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law,  (iii) under Section 174 of the Delaware  General  Corporation
Law, or (iv) for any  transaction  from which the  director  derived an improper
personal  benefit.  If the Delaware  General  Corporation  Law is amended  after
approval by the  shareholders  of this  article to  authorize  corporate  action
further  eliminating or limiting the personal  liability of directors,  then the
liability of a director of the corporation shall be eliminated or limited to the
fullest extent permitted by the Delaware General Corporation Law, as so amended.

     Any repeal or modification of the foregoing  paragraph by the  shareholders
of the  corporation  shall not  adversely  affect any right or  protection  of a
director of the corporation existing at the time of such repeal or modification.

     IN WITNESS WHEREOF, this Restated Certificate of Incorporation,  which only
restates  and  integrates  and does not  further  amend  the  provisions  of the
corporation's   Certificate   of   Incorporation   as   heretofore   amended  or
supplemented,  there  being no  discrepancy  between  those  provisions  and the
provisions of this Restated  Certificate of Incorporation except as permitted by
Section 245 of the General Corporation Law of Delaware, having been duly adopted
by the  corporation's  Board of Directors in accordance  with Section 245 of the
General  Corporation Law, has been executed by its duly authorized  officer this
1st day of October, 1999.

                                    EXHIBIT I


            SERIES A JUNIOR PARTICIPATING CUMULATIVE PREFERRED STOCK

     Section 1.  Designation  and  Amount.  The shares of such  series  shall be
designated as Series A Junior  Participating  Cumulative  Preferred  Stock,  par
value $.10 per share (the "Series A Preferred Stock"),  and the number of shares
constituting such series shall be 3,000,000.

     Section 2.  Dividends and Distributions.

     (a) The holders of shares of Series A Preferred Stock, in preference to the
holders of shares of Common  Stock,  $1.00 per share,  of the  Corporation  (the
"Common  Stock") and of any other  junior stock of the  Corporation  that may be
outstanding, shall be entitled to receive, when, as and if declared by the Board
of Directors out of funds legally available for the purpose, quarterly dividends
payable in cash on the tenth day of  January,  April,  July and  October in each
year (each such date being referred to herein as a "Quarterly  Dividend  Payment
Date"),  commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction  of a share of Series A Preferred  Stock,  in an
amount per share (rounded to the nearest cent) equal to the greater of (i) $0.25
per share ($1.00 per annum),  or (ii) subject to the  provision  for  adjustment
hereinafter  set forth,  100 times the  aggregate  per share  amount of all cash
dividends, and 100 times the aggregate per share amount (payable in kind) of all
non-cash  dividends  or other  distributions,  other than a dividend  payable in
shares of Common Stock,  or a subdivision  of the  outstanding  shares of Common
Stock (by reclassification or otherwise), declared on the Common Stock since the
immediately  preceding  Quarterly  Dividend Payment Date or, with respect to the
first Quarterly  Dividend Payment Date, since the first issuance of any share or
fraction  of a share  of  Series  A  Preferred  Stock.  In the  event  that  the
Corporation  shall at any time  declare  or pay any  dividend  on  Common  Stock
payable in shares of Common Stock,  or effect a subdivision  or  combination  or
consolidation of the outstanding shares of Common Stock (by  reclassification or
otherwise)  into a greater or lesser number of shares of Common Stock,  then and
in each such event,  the amount to which holders of shares of Series A Preferred
Stock were  entitled  immediately  prior to such event under  clause (ii) of the
preceding  sentence shall be adjusted by multiplying  such amount by a fraction,
the  numerator  of which is the  number of shares  of Common  Stock  outstanding
immediately  after such  event,  and the  denominator  of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

     (b) The Corporation  shall declare a dividend or distribution on the Series
A Preferred  Stock as provided in paragraph  (a) of this  Section 2  immediately
after it declares a dividend or  distribution  on the Common Stock (other than a
dividend  payable in shares of Common  Stock);  provided,  however,  that in the
event no dividend or  distribution  shall have been declared on the Common Stock
during the period  between  any  Quarterly  Dividend  Payment  Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $0.25 per share ($1.00
per annum) on the Series A Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

     (c) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A  Preferred  Stock  from the  Quarterly  Dividend  Payment  Date next
preceding the date of issue of such shares of Series A Preferred  Stock,  unless
the date of issue of such  shares  is  prior to the  record  date for the  first
Quarterly  Dividend  Payment Date, in which case  dividends on such shares shall
begin to accrue  from the date of issue of such  shares,  or unless  the date of
issue is a Quarterly  Dividend  Payment  Date or is a date after the record date
for the  determination of holders of shares of Series A Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment Date,
in either of which cases such dividends  shall begin to accrue and be cumulative
from such Quarterly  Dividend  Payment Date.  Accrued but unpaid dividends shall
cumulate but shall not bear  interest.  Dividends paid on the shares of Series A
Preferred Stock in an amount less than the total amount of such dividends at the
time  accrued  and  payable  on such  shares  shall be  allocated  pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Directors  may fix a record date for the  determination  of holders of shares of
Series  A  Preferred  Stock  entitled  to  receive  payment  of  a  dividend  or
distribution declared thereon,  which record date shall be not more than 60 days
prior to the date fixed for the payment thereof.

     Section 3. Voting Rights. The holders of shares of Series A Preferred Stock
shall have the following voting rights:

     (a) Each share of Series A Preferred Stock shall entitle the holder thereof
to 100 votes (and each one  one-hundredth of a share of Series A Preferred Stock
shall entitle the holder thereof to one vote) on all matters  submitted toa vote
of the stockholders of the Corporation.  In the event that the Corporation shall
at any time  declare or pay any  dividend on Common  Stock  payable in shares of
Common Stock or effect a subdivision  or  combination  or  consolidation  of the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock,  then and in each such event, the number of votes per
share to which  holders  of shares of Series A  Preferred  Stock  were  entitled
immediately  prior to such event shall be adjusted by multiplying such number by
a  fraction,  the  numerator  of which is the  number of shares of Common  Stock
outstanding  immediately  after such event,  and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     (b) Except as otherwise provided in the Certificate of Incorporation of the
Corporation  or herein or by law,  the  holders of shares of Series A  Preferred
Stock and the holders of shares of Common Stock shall vote together as one class
on all matters submitted to a vote of stockholders of the Corporation.

     (c) In  addition,  the holders of shares of Series A Preferred  Stock shall
have the following special voting rights:

     In the  event  that at any time  dividends  on  Series A  Preferred  Stock,
     whenever accrued and whether or not  consecutive,  shall not have been paid
     or declared and a sum sufficient for the payment  thereof set aside,  in an
     amount  equivalent  to six  quarterly  dividends  on all shares of Series A
     Preferred Stock at the time  outstanding,  then and in each such event, the
     holders  of shares of Series A  Preferred  Stock and each  other  series of
     preferred  stock now or hereafter  issued that shall be accorded such class
     voting  right by the Board of  Directors  and that  shall have the right to
     elect three  directors  as the result of a prior or  subsequent  default in
     payment  of  dividends  on  such  series  (each  such  other  series  being
     hereinafter called "Other Series of Preferred Stock"), voting separately as
     a class  without  regard  to  series,  shall be  entitled  to  elect  three
     directors at the next annual meeting of stockholders of the Corporation, in
     addition to the directors to be elected by the holders of all shares of the
     Corporation entitled to vote for the election of directors, and the holders
     of all shares  (including the Series A Preferred Stock) otherwise  entitled
     to vote for directors,  voting separately as a class,  shall be entitled to
     elect the remaining  members of the Board of  Directors,  provided that the
     Series A Preferred Stock and each Other Series of Preferred  Stock,  voting
     as a class,  shall not have the right to elect more than  three  directors.
     Such  special  voting  right of the holders of shares of Series A Preferred
     Stock may be  exercised  until all  dividends  in  default  on the Series A
     Preferred  Stock  shall  have  been  paid  in full or  declared  and  funds
     sufficient  therefor  set aside,  and when so paid or  provided  for,  such
     special  voting right of the holders of shares of Series A Preferred  Stock
     shall cease,  but subject always to the same  provisions for the vesting of
     such special voting rights in the event of any such future dividend default
     or  defaults.  At any time after such special  voting  rights shall have so
     vested in the holders of shares of Series A Preferred  Stock, the Secretary
     of the  Corporation  may,  and upon the  written  request of the holders of
     record of 10% or more in number of the shares of Series A  Preferred  Stock
     and each Other Series of Preferred Stock then outstanding  addressed to the
     Secretary at the principal  executive office of the Corporation shall, call
     a special  meeting of the holders of shares of Preferred  Stock so entitled
     to vote,  for the election of the directors to be elected by them as herein
     provided,  to be held  within 60 days  after such call and at the place and
     upon the  notice  provided  by law and in the  Bylaws  for the  holding  of
     meetings of stockholders;  provided,  however, that the Secretary shall not
     be required to call such  special  meeting in the case of any such  request
     received less than 90 days before the date fixed for any annual  meeting of
     stockholders,  and if in such case such  special  meeting  is not called or
     held, the holders of shares of Preferred Stock so entitled to vote shall be
     entitled to exercise the special  voting rights  provided in this paragraph
     at such annual meeting.  If any such special meeting  required to be called
     as above provided shall not be called by the Secretary within 30 days after
     receipt of any such  request,  then the holders of record of 10% or more in
     number of the shares of Series A Preferred  Stock and each Other  Series of
     Preferred  Stock then  outstanding  may  designate  in writing one of their
     number to call such  meeting,  and the  person so  designated  may,  at the
     expense of the  Corporation,  call such meeting to be held at the place and
     upon the  notice  given by such  person,  and for that  purpose  shall have
     access to the

                                        5
<PAGE>
     stock books of the Corporation.  No such special meeting and no adjournment
     thereof  shall  be held on a date  later  than 60 days  before  the  annual
     meeting  of  stockholders.  If, at any  meeting  so called or at any annual
     meeting  held while the holders of shares of Series A Preferred  Stock have
     the special voting rights  provided for in this  paragraph,  the holders of
     not less than 40% of the shares of Series A Preferred  Stock and each Other
     Series of  Preferred  Stock then  outstanding  are  present in person or by
     proxy,  which percentage shall be sufficient to constitute a quorum for the
     election of additional  directors as herein  provided,  the then authorized
     number of directors of the  Corporation  shall be increased by three, as of
     thetime  of such  special  meeting  or the time of the  first  such  annual
     meeting held while such holders have special  voting rights and such quorum
     is present,  and the holders of shares of Series A Preferred Stock and each
     Other Series of Preferred  Stock,  voting as a class,  shall be entitled to
     elect the  additional  directors so provided  for. If the  directors of the
     Corporation  are  then  divided  into  classes  under   provisions  of  the
     Certificate of  Incorporation  of the Corporation or the Bylaws,  the three
     additional  directors  shall be  members  of those  respective  classes  of
     directors in which a vacancy is created as a result of such increase in the
     authorized number of directors.  If the foregoing  expansion of the size of
     the Board of Directors  shall not be valid under  applicable  law, then the
     holders of shares of Series A Preferred  Stock and of each Other  Series of
     Preferred Stock,  voting as a class,  shall be entitled,  at the meeting of
     stockholders  at which they would  otherwise have voted, to elect directors
     to fill any then existing  vacancies on the Board of  Directors,  and shall
     additionally be entitled,  at such meeting and each  subsequent  meeting of
     stockholders at which directors are elected,  to elect all of the directors
     then being  elected  until by such class vote three members of the Board of
     Directors  have been so elected.  Upon the  election at such meeting by the
     holders  of shares of Series A  Preferred  Stock and each  Other  Series of
     Preferred  Stock,  voting as a class, of the directors they are entitled so
     to elect,  the persons so  elected,  together  with such  persons as may be
     directors  or as may have been  elected as  directors by the holders of all
     shares (including Series A Preferred Stock) otherwise  entitled to vote for
     directors,  shall constitute the duly elected directors of the Corporation.
     The  additional  directors  so  elected  by  holders  of shares of Series A
     Preferred  Stock and each  Other  Series of  Preferred  Stock,  voting as a
     class,  shall serve until the next annual meeting or until their respective
     successors  shall be elected and  qualified,  or if any such  director is a
     member of a class of directors under provisions dividing the directors into
     classes,  each such director  shall serve until the annual meeting at which
     the term of office of such  director's  class  shall  expire or until  such
     director's  successor  shall be  elected  and  shall  qualify,  and at each
     subsequent  meeting  of  stockholders  at  which  the  directorship  of any
     director  elected by the vote of  holders  of shares of Series A  Preferred
     Stock and each Other  Series of  Preferred  Stock under the special  voting
     rights set forth in this  paragraph is up for election,  said special class
     voting  rights  shall apply in the  reelection  of such  director or in the
     election of such director's successor; provided, however, that whenever the
     holders  of shares of Series A  Preferred  Stock and each  Other  Series of
     Preferred  Stock shall be  divested  of the  special  rights to elect three
     directors as above provided,  the terms of office of all persons elected as
     directors  by the  holders of shares of Series A  Preferred  Stock and each
     Other Series of Preferred Stock,  voting as a class, or elected to fill any
     vacancies resulting from the death, resignation, or removal of directors so
     elected by the holders of shares of Series A Preferred Stock and each Other
     Series of Preferred  Stock,  shall forthwith  terminate and, if applicable,
     the number of directors shall be reduced accordingly. If, at any time after
     a special  meeting of  stockholders or an annual meeting of stockholders at
     which the  holders  of shares of Series A  Preferred  Stock and each  Other
     Series of Preferred  Stock,  voting as a class,  have elected  directors as
     provided above, and while the holders of shares of Series A Preferred Stock
     and each Other  Series of  Preferred  Stock  shall be  entitled so to elect
     three  directors,  the  number of  directors  who have been  elected by the
     holders  of shares of Series A  Preferred  Stock and each  Other  Series of
     Preferred  Stock (or who by reason of one or more  resignations,  deaths or
     removals  have  succeeded  any  directors  so  elected)  shall by reason of
     resignation,  death or removal  be less than  three but at least  one,  the
     vacancy in the  directors so elected by the holders of shares of the Series
     A Preferred Stock and each Other Series of Preferred Stock may be filled by
     the remaining director elected by such holders,  and in the event that such
     election  shall not occur within 30 days after such vacancy  arises,  or in
     the event  that  there  shall not be  incumbent  at least one  director  so
     elected by such holders, the Secretary of the Corporation may, and upon the
     written  request  of the  holders of record of 10% or more in number of the
     shares of Series A Preferred Stock and each Other Series of Preferred Stock
     then outstanding  addressed to the Secretary at the principal office of the
     Corporation  shall,  call a special  meeting  of the  holders  of shares of
     Series A  Preferred  Stock  and each  Other  Series of  Preferred  Stock so

     stockholders;  provided,  however, that the Secretary shall not be required
     to call such special meeting in the case of any such request  received less
     than 90 days before the date fixed for any annual meeting of  stockholders,
     and if in such case such  special  meeting is not  called,  the  holders of
     shares of  Preferred  Stock so  entitled  to vote shall be entitled to fill
     such  vacancy or  vacancies  at such annual  meeting.  If any such  special
     meeting  required to be called as above provided shall not be called by the
     Secretary  within  30 days  after  receipt  of any such  request,  then the
     holders  of  record  of 10% or more in  number  of the  shares  of Series A
     Preferred Stock and each Other Series of Preferred  Stock then  outstanding
     may designate in writing one of their number to call such meeting,  and the
     person so  designated  may,  at the expense of the  Corporation,  call such
     meeting to be held at the place and upon the notice above provided, and for
     that purpose  shall have access to the stock books of the  Corporation;  no
     such special  meeting and no  adjournment  thereof  shall be held on a date
     later than 60 days before the annual meeting of stockholders.

     (d) Nothing herein shall prevent the directors or stockholders  from taking
any action to  increase  the number of  authorized  shares of Series A Preferred
Stock,  or increasing the number of authorized  shares of Preferred Stock of the
same class as the Series A Preferred Stock or the number of authorized shares of
Common Stock, or changing the par value of the Common Stock or Preferred  Stock,
or issuing options,  warrants or rights to any class of stock of the Corporation
as authorized by the Certificate of Incorporation of the Corporation,  as it may
hereafter be amended.

     (e) Except as set forth  herein,  holders  of shares of Series A  Preferred
Stock  shall  have no  special  voting  rights  and their  consent  shall not be
required  (except to the extent  they are  entitled  to vote as set forth in the
Certificate of  Incorporation of the Corporation or herein or by law) for taking
any corporate action.

     Section 4.  Certain Restrictions.

     (a) Whenever any dividends or other  distributions  payable on the Series A
Preferred  Stock as provided in Section 2 hereof are in arrears,  thereafter and
until all  accrued  and  unpaid  dividends  and  distributions,  whether  or not
declared, on shares of Series A Preferred Stock outstanding shall have been paid
in full,  the  Corporation  shall not and shall cause its  subsidiaries  not to,
directly or indirectly:

          (i) declare or pay dividends on, or make any other  distributions with
     respect to, any shares of stock ranking  junior  (either as to dividends or
     upon  liquidation,  dissolution  or winding  up) to the Series A  Preferred
     Stock;

          (ii) declare or pay dividends on, or make any other distributions with
     respect to, any shares of stock ranking on a parity (either as to dividends
     or upon liquidation, dissolution or winding up) with the Series A Preferred
     Stock,  except  dividends  paid ratably on shares of the Series A Preferred
     Stock  and all such  parity  stock on which  dividends  are  payable  or in
     arrears in proportion to the total amounts to which the holders of all such
     shares are then entitled;

          (iii) redeem or purchase or otherwise acquire for consideration shares
     of any stock ranking  junior  (either as to dividends or upon  liquidation,
     dissolution or winding up) with the Series A Preferred Stock, provided that
     the  Corporation  may at any time  redeem,  purchase or  otherwise  acquire
     shares of any such junior  stock in exchange for shares of any stock of the
     Corporation  ranking  junior  (either as to dividends or upon  dissolution,
     liquidation or winding up) to the Series A Preferred Stock; or

          (iv)  purchase or otherwise  acquire for  consideration  any shares of
     Series A Preferred  Stock,  or any shares of stock ranking on a parity with
     the Series A Preferred  Stock,  except in accordance  with a Purchase offer
     made in writing or by publication (as determined by the Board of Directors)
     to all holders of such  shares  upon such terms as the Board of  Directors,
     after  consideration  of the  respective  annual  dividend  rates and other
     relative rights and preferences of the respective series and classes, shall
     determine in good faith will result in fair and equitable  treatment  among
     the respective series or classes.

                                       7
<PAGE>
    (b) The  Corporation  shall not permit any subsidiary of the Corporation to
purchase  or  otherwise  acquire  for  consideration  any shares of stock of the
Corporation unless the Corporation could, under paragraph (a) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

     Section  5.  Reacquired  Shares.  Any  shares of Series A  Preferred  Stock
purchased  or otherwise  acquired by the  Corporation  in any manner  whatsoever
shall be retired and cancelled promptly after the acquisition  thereof. All such
shares shall upon their  cancellation  become  authorized but unissued shares of
preferred stock,  without  designation as to series, and may be reissued as part
of any series of preferred  stock created by resolution  or  resolutions  of the
Board  of  Directors  (including  Series  A  Preferred  Stock),  subject  to the
conditions and restrictions on issuance set forth herein.

     Section 6.  Liquidation,  Dissolution or Winding Up. Upon any  liquidation,
dissolution or winding up of the Corporation, no distribution shall be made to:

     (a) the holders of shares of stock ranking  junior  (either as to dividends
or upon liquidation,  dissolution or winding up) to the Series A Preferred Stock
unless,  prior thereto,  the holders of shares of Series A Preferred Stock shall
have received the greater of (i) $100.00 per share ($1.00 per one  one-hundredth
of a  share),  plus  an  amount  equal  to  accrued  and  unpaid  dividends  and
distributions thereon,  whether or not declared, to the date of such payment, or
(ii) an aggregate  amount per share,  subject to the  provision  for  adjustment
hereinafter set forth, equal to 100 times the aggregate amount to be distributed
per share to holders of shares of Common Stock; or

     (b) the  holders  of  shares of stock  ranking  on a parity  (either  as to
dividends  or upon  liquidation,  dissolution  or winding  up) with the Series A
Preferred  Stock,  except  distributions  made ratably on the Series A Preferred
Stock and all other such  parity  stock in  proportion  to the total  amounts to
which the  holders  of all such  shares  are  entitled  upon  such  liquidation,
dissolution or winding up. In the event that the  Corporation  shall at any time
declare or pay any dividend on Common Stock  payable in shares of Common  Stock,
or effect a subdivision  or  combination  or  consolidation  of the  outstanding
shares of Common  Stock (by  reclassification  or  otherwise)  into a greater or
lesser  number  of  shares of Common  Stock,  then and in each such  event,  the
aggregate  amount to which  holders of shares of Series A  Preferred  Stock were
entitled  immediately prior to such event under the proviso in clause (a) of the
preceding  sentence shall be adjusted by multiplying  such amount by a fraction,
the  numerator  of which is the  number of shares  of Common  Stock  outstanding
immediately  after such  event,  and the  denominator  of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

     Section 7.  Consolidation,  Merger,  etc. In the event that the Corporation
shall enter into any consolidation,  merger, combination or other transaction in
which the shares of Common Stock are  exchanged  for or changed into other stock
or securities, cash and/or any other property, or otherwise changed, then and in
each such event,  the shares of Series A Preferred  Stock shall at the same time
be  similarly  exchanged  or  changed  in an amount  per share  (subject  to the
provision for adjustment hereinafter set forth) equal to 100 times the aggregate
amount of stock,  securities,  cash and/or any other property (payable in kind),
as the case may be,  into  which or for  which  each  share of  Common  Stock is
changed  or  exchanged.  In the  event  that the  Corporation  shall at any time
declare or pay any dividend on Common Stock  payable in shares of Common  Stock,
or effect a subdivision  or  combination  or  consolidation  of the  outstanding
shares of Common  Stock (by  reclassification  or  otherwise)  into a greater or
lesser number of shares of Common Stock, then and in each such event, the amount
set forth in the  preceding  sentence  with respect to the exchange or change of
shares of Series A Preferred Stock shall be adjusted by multiplying  such amount
by a fraction,  the  numerator  of which is the number of shares of Common Stock
outstanding  immediately  after such event,  and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     Section 8. No Redemption.  The shares of Series A Preferred Stock shall not
be redeemable. Notwithstanding the foregoing, the Corporation may acquire shares
of  Series  A  Preferred  Stock  in any  other  manner  permitted  by  law,  the
Certificate of Incorporation of the Corporation or herein.

     Section  9.  Rank.   Unless  otherwise   provided  in  the  Certificate  of
Incorporation of the Corporation or a Certificate of Designations  relating to a
subsequent series of preferred stock of the Corporation,  the Series A Preferred
Stock shall rank junior to all other series of the Corporation's preferred stock
as to the payment of dividends and the  distribution  of assets on  liquidation,
dissolution or winding up, and senior to the Common Stock of the Corporation.

                                       8
<PAGE>
     Section 10. Amendment.  The Certificate of Incorporation of the Corporation
shall not be amended in any manner that would  materially and adversely alter or
change the powers, preferences or special rights of the Series A Preferred Stock
without  the  affirmative  vote of the  holders  of at least  two-thirds  of the
outstanding  shares of Series A  Preferred  Stock,  voting  together as a single
series.

     Section 11.  Fractional  Shares.  Series A Preferred  Stock maybe issued in
fractions  of a share (in one  one-hundredths  (1/100)  of a share and  integral
multiples thereof) that shall entitle the holder thereof,  in proportion to such
holder's  fractional  shares,  to exercise  voting  rights,  receive  dividends,
participate in distributions and have the benefit of all other rights of holders
of shares of Series A Preferred Stock.

               employment  described in Section 2(a) as long as such services do
               not compromise  Employee's  obligations  under Sections 6 or 7 of
               this  Agreement  or are  not  with  respect  to the  oil  and gas
               exploration  and  production  business  in a country in which the

          3. Compensation.

               (a) Salary.

               During the period January 1, 2000 through  December 31, 2000 term
               of employment  described in Section 2(a), and in consideration of
               Employee  services as a Consulting  Employee and his agreement to

               Employee  shall  receive  a  salary,   payable  in   semi-monthly
               installments,  of $525,000 less Applicable Withholding.  Employee

               accrue  any  vacation  pay  for the  period  of his  status  as a
               Consulting Employee.

               (b) Revised Incentive Compensation Plan.

               Employee  shall  receive  distribution  of the  cash  portion  of
               deferred  RICP awards made with respect to years prior to 1999 in

               and non-forfeitable  basis.  Employee shall receive an RICP award
               for calendar year 1999 equal to that which he would have received
               had the Companies not terminated his employment  under Section 1.

               respect to such  adjustments,  Employee shall be treated at least
               as well as employees  at or above his salary  grade level.  There

               Employee's  individual  performance.  If the RICP is interpreted,
               modified,  amended or terminated,  or the Management  Development
               and Compensation  Committee  ("Committee")  thereunder acts, in a
               manner which would result in the  foregoing  award (after  having
               been rendered in a manner that is non-discriminatory  relative to
               Employee)  being reduced,  Employee  shall receive a bonus,  less
               Applicable Withholding, in the amount of such reduction,  payable
               at the time  the  RICP  award is  payable,  or  would  have  been
               payable.

               (1) Performance Shares.

               awards are generally  paid)  subject only to the  following  LTIP
               variables:

                    (a)  Pro-ration  for service  under  Section  8(d)(I) of the
                         LTIP  shall  be as  described  in  Column  C above  for
                         termination  of  employment  on March 31, 2001;  in the
                         event  of  an  earlier   termination  of  the  term  of
                         employment  described in Section 2(a), the date of such
                         termination  shall not be  earlier  than the  Effective
                         Date  and  the   pro-ration   shall  be  based  on  the
                         principles used to derive Column C above.

                    (b)  The original  Performance  Share award shall be subject
                         to  variation  in  accordance  with Section 8(b) of the
                         LTIP   and  the   "Peer   Group   Companies"   relative
                         performance   fraction   contemplated   by   the   LTIP
                         agreement.

                         Performance Cycle.

                    (d)  LTIP Rights Vested; No Further Awards.  The termination
                         of the term of Employee's employment under Section 2 by
                         reason of  Section  8(b)  shall not  modify  Employee's
                         rights under this Section 3(c).  Employee  shall not be
                         eligible for any additional  grants under the Long Term
                         Incentive Plan of 1998 after the Effective Date.

               (2)  Stock Options.

               The parties acknowledge and agree that Employee has been awarded,
               under  the  LTIP,  Option  Grants  dated as set forth in Column A
               below, the number of non-qualified stock options appearing to the
               right of each Option grant in Column B below,  exercisable at the
               applicable  strike  price  set  forth in  Column C below and that
               under the terms of the Option  Grants,  such Option Grants become
               exercisable in accordance  with the terms  increments  over the 3
               years  following  the  Option  Grant date and will  therefore  be
               exercisable in the numbers set forth in Column D below,  assuming
               Employee's employment continues through March 31, 2001:

               Companies agree that the exercisable  options described in Column
               D are  vested and  non-forfeitable  and shall be  exercisable  by
               Employee without  restriction  until the earlier of (I) the tenth
               anniversary  of the  grant or (ii) the third  anniversary  of the
               termination  of the term of Employee's  employment  under Section
               2(a).

               (3) Restricted Shares.

               The parties acknowledge and agree that Employee has 14,932 shares
               of Restricted  Stock  resulting from his deferral of a portion of
               RICP awards, as of the effective date.  Notwithstanding any other
               provisions of this Agreement, such Restricted Stock shall be 100%
               vested and  non-forfeitable,  and distributed to Employee without
               restriction,  on the  earlier of the  termination  of the term of
               employment   described   in  Section  2(a)  or  March  31,  2001.
               Notwithstanding  any other  provisions  of this  Agreement,  such
               Restricted  Stock shall be 100% vested and  non-forfeitable,  and
               distributed to Employee  without  restriction,  on the earlier of
               the termination of the restrictions thereunder or April 6, 2001.

               (4) Performance Stock Options.

               Employee  will continue to "time vest" in his  Performance  Stock
               Options.  Employee was granted 400,000  Performance Stock Options
               in 1998 and such options will be 100% vested and  non-forfeitable
               if he  remains  an  employee  until  March  31,  2001 and will be
               subject to pro rata  vesting in the event of earlier  termination
               of  employment.  The options  remain  subject to the terms of the
               plan,  including  satisfaction  of the  performance  requirements
               necessary for them to become exercisable.

               In the event that  Employee's  Performance  Stock Options fail to
               become  exercisable  solely because the performance  requirements
               necessary for them to become  exercisable  have not been met, the
               Companies  shall pay to  Employee  not later than April 6, 2001 a
               lump sum cash settlement amount determined in accordance with the
               terms of the Unocal Retirement Plan equal to the benefit accruals
               that  would  have  occurred  in the  aggregate  under the  Unocal
               Retirement  Plan  and  the  Non-Qualified  Retirement  Plans  had
               Employee  continued  employment  for three (3)  additional  years
               beyond the date of his  termination.  Said three (3) year  period
               shall be reduced by the amount of any service  recognized by said
               plans for the period of January 1, 2001  through  March 31,  2001
               and  using  "includable  compensation"  currently  as used in the
               Unocal  Retirement  Plan with respect to Employee as of March 31,
               2001. "Includable Compensation" for purposes of the Non-Qualified
               Retirement Plan shall not be subject to any Internal Revenue Code
               limitations.


               (d) Benefits.

               (1) Participation After Effective Date.

               On  and  after  the  Effective  Date,  and  during  the  term  of
               Employee's employment under Section 2(a) above, Employee shall be
               entitled to  participate  in all Benefit Plans and fringe benefit
               and payroll  practices of Unocal on the same terms and conditions
               as would be applicable were Employee serving,  during the term of
               employment  described  in  Section  2(a),  in good  standing  and
               receiving as compensation the amounts described in Sections 3(a),
               3(b),  3(c)  and  3(d) of this  Agreement.  For  purposes  of the
               preceding  sentence,  "terms and  conditions"  includes  Employee
               making  required  elections,   and  Employee's  paying  generally
               applicable employee  contributions  required by a Benefit Plan to
               obtain one or more benefits  under the Benefit Plan.  If, for any
               reason, Employee does not receive, pursuant to a Benefit Plan, at
               the time required by such Benefit Plan, all or any portion of the
               benefit under such Benefit Plan as  contemplated  by this Section
               3(d), the Companies  shall be jointly and severally  obligated to
               provide the Employee the After Tax  Equivalent of the benefit not
               then received by the Employee  pursuant to the Benefit Plan.  The
               parties agree that the rights and  obligations  created under the
               preceding sentence are contractual rights and obligations between
               Employee and the Companies  under the law of California,  and not
               rights and obligations under a Benefit Plan.

               (a) Without  limiting the  foregoing  Section  3(a)(1),  Employee
               shall continue to accrue Benefit  Service under Unocal's  defined
               benefit  and  defined   contribution  plans  under  which  he  is
               currently covered. Any amendment to the Unocal Retirement Plan or
               any of the  Non-Qualified  Retirement Plans which would adversely
               affect the Employee's benefit thereunder shall be of no force and
               effect with respect to the Employee  except where such  amendment
               also adversely  affects the benefit with respect to the Company's
               most senior executives in a substantially identical manner.


               (b) Retiree Health Benefits.

               Companies  hereby  acknowledge  and  agree  that  Employee  shall
               continue  to  be  eligible,  during  all  periods  following  the
               termination of his employment  under Section 2(a), to participate
               in those Benefit Plans providing  post-retirement health benefits
               in  accordance  with the terms thereof as applicable to similarly
               situated former employees.

               (c) Financial Counseling.

               Employee shall remain eligible for financial  counseling services
               through December 31, 2001.

          4. Severance Payment

               Employee shall receive  payments in accordance with the terms set
               forth in Appendix A hereto. The Company's  obligations under this
               Section 4, as set forth in  Appendix A hereto  shall  survive the
               termination  of this  Agreement,  whether  pursuant  to Section 9
               hereof  or  otherwise.  This  payment  shall  be made as early as
               practical in the calendar year 2000  following the  completion of
               the RICP calculation in respect of the 1999 calendar year.


          5. Retirement Plans

               (a) Qualified  Plan. Not later than 30 days  following  Company's
               receipt  of  all  required  and  properly  completed  forms,  the
               Companies  shall pay (or cause to be paid) to Employee a lump sum
               amount in cash equal to the present value of  Employee's  accrued
               benefit under the Unocal  Retirement  Plan accrued  through March
               31, 2001 (assuming Employee's employment through March 31, 2001.)

               (b)  Non-Qualified  Plans.  Not  later  than  30  days  following
               Company's  receipt of all required and properly  completed forms,
               the  Companies  shall pay to  Employee  a lump sum amount in cash
               equal to the present  value of Employee's  accrued  benefit under
               the Non-Qualified Retirement Plans accrued through March 31, 2001
               (assuming Employee's employment through March 31, 2001).

               (c) Certain Assumptions. For purposes of calculating the benefits
               payable under  Sections  5(a) and (b) above,  [in addition to the
               assumptions  set forth on Exhibit A hereto,] the Companies  shall
               (1) credit  Employee with 60 years, 4 months of age and 37 years,
               10  months  service  (provided  that  if  Employee's   employment
               terminates  prior  to  March  31,  2001  the  Companies  shall be
               entitled to a reduction in such age and service  assumptions on a
               month-for-month   basis),   (ii)   use   Employee's   "includible
               compensation"  in effect as of March 31,  2001,  (iii)  take into
               account any  increases in IRC section 415 limits taking effect as
               of or prior to March 31,  2001,  and (iv) take into  account  any
               changes in the terms of the Unocal  Retirement Plan taking effect
               as of or prior to March 31,  2001 that would  result in a greater
               benefit becoming payable to employee,  to the extent allowable by
               law and applicable regulations.

          6. Confidential Information.

               Employee  acknowledges  that in the  course of  carrying  out his
               responsibilities    to   Companies,    he   has   had   fiduciary
               responsibilities  to Companies and has had access to and has been
               entrusted with the confidential  and proprietary  information and
               trade  secrets  of  Companies   including,   without  limitation,
               information  not  previously  disclosed  to the public  regarding
               current and projected revenues,  expenses,  costs, profit margins
               and any other financial and budgeting information;  marketing and
               distribution  plans  and  practices;   manufacturing   processes,
               formulae,  methods  and  facilities;  research  and  development;
               business  plans,  opportunities,  projects and any other business
               and corporate strategies; product information including reserves,
               exploration   and   research;   terms  of  contracts   and  other
               arrangements  with customers  suppliers,  agents and employees of
               Companies;  confidential  and  sensitive  information  of  record
               regarding  other  employees   (other  than  Employee's   personal
               opinions),  including  information  with  respect  to  their  job
               descriptions,  documented  performance  strengths and weaknesses,
               and  compensation;  and other  information  not  generally  known
               regarding   the   business,   affairs  and  plans  of   Companies
               (collectively,   the   "Confidential   Information").    Employee
               acknowledges   that  the   unauthorized   use  or  disclosure  of
               Confidential  Information  would be  detrimental to Companies and
               would reasonably be anticipated to materially  impair  Companies'
               value.  Employee  acknowledges and agrees that such  Confidential
               Information  is the  exclusive  property of Companies and that he
               shall not at any time,  without the prior  written  consent of an
               authorized  officer of Unocal  either  during his  employment  by
               Companies or after the termination of that  employment,  directly
               or indirectly  use for himself or others,  or disclose to others,
               any  Confidential  Information.  The foregoing shall not apply to
               information which either (I) is known to Employee other than as a
               result of work  performed for Companies and from some  authorized
               source  other  than  Companies,  (ii) is or  becomes  part of the
               public  domain,  other  than by  Employee's  direct  or  indirect
               disclosure,  or  (iii)  consists  of  explanations  of  his  work
               experience  that  are  reasonably   necessary  to  interview  for
               employment.  Employee's  obligations  under this paragraph  shall
               survive  termination  of his  employment  as described in Section
               2(a) for a period of two years  from such  termination.  Employee
               represents  he has made  available to Companies  all of his files
               and materials  taken from his Unocal  office,  and Companies have
               had an  opportunity  to inspect same,  and Companies  acknowledge
               that  such   files  and   materials   contain   no   Confidential
               Information.

          7. Change of Control.

               Employee  agrees  that  during  the  period   commencing  on  the
               Effective  Date and  ended two years  after  the  termination  of
               Employee's employment as described in Section 2(a). Employee will
               not directly or indirectly participate in or assist any person or
               entity in activities designed to effectuate, or reasonably likely
               to  result   in,  a  change  in   control   of  Unocal  or  other
               extraordinary   transaction   involving  Unocal.   The  foregoing
               sentence  shall not be  interpreted  as preventing  Employee from
               holding a position  with an  employer  where  Employee is "walled
               off" from any activity prohibited to Employee under this Section.
               Without  limiting  the  generality  of  the  preceding  sentence,
               activities  prohibited  by this  paragraph  7 include  activities
               designed to effectuate,  or reasonably  likely to result in (I) a
               merger or consolidation  involving  Unocal,  (ii) a sale or other
               disposition of all, or a substantial portion of, Unocal's assets,
               (iii) any  transaction  that  would  require  a vote of  Unocal's
               stockholders  under  Unocal's  Certificate  of  Incorporation  or
               bylaws  or under  applicable  law,  (iv)  any  person  or  entity
               (individually  or as a group  within  the  meaning  of Rule 13d-3
               promulgated  under  the  Securities  Exchange  Act  of  1934,  as
               amended)  becoming  the  beneficial  owner  of 15% or more of the
               combined  voting  owner  of  Unocal's   then-outstanding   equity
               securities or (v) a change in the  composition  of Unocal's Board
               of  Directors  such than,  during  any period of two  consecutive
               calendar  years,  Continuing  Directors (as defined below) cease,
               for any reason, to constitute at least a majority of the Board of
               Directors  at the  beginning  of the  applicable  two year period
               together with new directors  whose  election by the  stockholders
               was approved by a vote of at least  two-thirds

               of the directors  than in office who either were directors at the
               beginning of the applicable two-year period or whose election was
               previously  approved.  Employee  acknowledges  and agrees that in
               light of Employee's position and history with Companies and their
               affiliates  and  the  circumstances  as  they  exist  as  of  the
               Effective  Date of this  Agreement,  it would be  impossible  for
               Employee to engage in any of the  activities  prohibited  by this
               paragraph 7 without making use of Confidential  Information,  and
               the prohibitions contained in this paragraph 7 are reasonable.

          8. Remedies:

               (1) Damages.

               The parties  agree that the damages  according  to proof shall be
               the remedy at law for breaches hereunder.  However, the Companies
               shall not be entitled to withhold any payment or portion  thereof
               provided  under Section 3 as an alleged  offset  against any such
               claim of  damages by the  Companies  unless  (i)  Companies  have
               submitted  the issue to  arbitration  under  Section 8 by written
               notice given in accordance  with the procedures  thereunder on or
               before  September  14,  1998  and (ii)  after a full  evidentiary
               hearing, the arbitrator determines that the Companies have such a
               right of  offset  as a matter  of law and that  there  has been a
               material breach by Employee of Section 7 hereof.

               (2) Companies' Equitable Remedies.

               Employee  acknowledges  and agrees that full  compliance with his
               obligations  under  Sections 6 or are essential to the Companies,
               and in the event of any breach or  threatened  breach by Employee
               of  Sections  5 or 6  Companies  will  sustain  losses  which are
               impossible  to determine  and not fully  compensable  by monetary
               damages.  Therefore,  Company  and/or Unocal shall be entitled to
               institute  and  prosecute  proceedings  in any court of competent
               jurisdiction  to enjoin any such breach or threatened  breach and
               to enforce the specific performance of such provisions.

               (3) Employee's Equitable Remedies.

               Companies  acknowledge  and agree that full compliance with their
               obligations  under this  Agreement are essential to the Employee,
               and in the event of any breach or threatened  breach by Companies
               of  this  Agreement,  Employee  will  sustain  losses  which  are
               impossible  to determine  and not fully  compensable  by monetary
               damages.  Therefore,  Employee shall be entitled to institute and
               prosecute  proceedings in any court of competent  jurisdiction to
               enjoin any such  breach or  threatened  breach and to enforce the
               specific performance of such provisions.

               (4) Defense of Validity.

               The Companies  agree to defend the validity of this  Agreement in
               any   proceeding,   which   threatens  to  make  this   Agreement
               unenforceable in any material respect.

          9. Termination of Employee.

               Employee's  employment  with the  Companies  described in Section
               2(a)  shall  terminate  only as a result of one of the  following
               conditions:

               (1) The termination of such employment  effective March 31, 2001,
               pursuant to the first sentence of Section 2(a).

               (2) The  Employee's  material  breach of  Employee's  obligations
               under Section 6 or 7 providing services to others contrary to the
               requirements of Section 2 (c).

               Parties")  from any and all  claims,  demands,  causes of action,
               obligations,  damages,  attorneys' fees, costs and liabilities of

               employment,   other  than  those  claims  arising  by  reason  of
               Employee's  rights under this  Agreement and Benefit Plans of the
               Companies  under  this  Agreement,  and hereby  covenants  not to
               assert  any  such   released   Claims   through  a  lawsuit,   an
               administrative  proceeding  or  otherwise.  This General  Release
               includes,  but is not limited to, claims  arising under  federal,
               state or local  laws  prohibiting  employment  discrimination  or

               to terminate its employees,  including without limitation the Age
               Discrimination  in Employment Act of 1967, Title VII of the Civil
               Rights Act of 1964,  and the Civil Rights Act of 1991.  Except as
               specifically  provided  herein,  nothing in this Agreement  shall
               affect in any way, apply to,  increase,  or diminish,  any rights
               which  Employee has with respect to benefits  under Benefit Plans
               that have accrued and vested as of the Effective Date. Nothing in
               this  Agreement  shall affect in any way,  apply to,  increase or
               diminish,  any  rights  which  Employee  ma have with  respect to

               from any and all claims, demands, causes of action,  obligations,
               damages,  attorneys'  fees,  costs and  liabilities of any nature
               whatsoever   ("Company  Claims"),   whether  or  not  now  known,
               suspected or asserted,  which Companies may have or claim to have
               against the Companies' Released Parties relating in any manner to
               Employee's  employment  with Companies  and/or the termination of
               such  employment  (other than Company  Claims  arising under this
               Agreement),  and hereby covenants not to assert any such released
               Company Claims through a lawsuit, an administrative proceeding or
               otherwise.

          12. Section 1542 Waiver.

               Companies and Employee waive all rights under Section 1542 of the
               Civil Code of California. That section reads as follows:

                           "A GENERAL  RELEASE  DOES NOT EXTEND TO CLAIMS  WHICH
                           THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS
                           FAVOR AT THE TIME OF EXECUTING THE RELEASE,  WHICH IF
                           KNOWN  BY  HIM  MUST  HAVE  MATERIALLY  AFFECTED  HIS
                           SETTLEMENT WITH THE DEBTOR."

               Employee's  and  Companies'   Released  Parties  as  provided  in
               Sections  9 and  10  hereof,  Companies  and  Employee  expressly
               acknowledge that Sections 9 and 10 of this Agreement are intended
               to release,  without limitation,  Claims and Company Claims which
               Companies or Employee do not know or suspect to exist in their or
               his favor at the time of execution of this document, and that the
               settlement  agreed upon completely  extinguishes  all such Claims
               and Company Claims.

               hereby  agree to submit any claim or dispute  arising  out of the
               terms of this  Agreement  (including  exhibits)  to  private  and
               confidential arbitration by a single neutral arbitrator.  Subject
               to the terms of this paragraph, the arbitration proceedings shall
               be governed by the Commercial  Arbitration  Rules of the American
               Arbitration  Association,  and shall  take  place in Los  Angeles
               County.  The  arbitrator  shall be  appointed by agreement of the
               parties  hereto  or,  if no  agreement  can  be  reached,  by the
               American  Arbitration  Association  pursuant  to its  Rules.  The
               decision  of the  arbitrator  shall be final and  binding  on all
               parties to this  Agreement , and judgment  thereon may be entered
               in any court having  jurisdiction.  All costs of the  arbitration
               proceeding  or litigation  to enforce this  Agreement,  including
               reasonable  attorneys' fees shall be paid to the prevailing party
               by the party  against whom the  arbitrator  or court  rules.  The
               parties shall  instruct the  arbitrator to specify which party is
               the  prevailing  party.   Except  for  claims  for  equitable  or
               injunctive relief,  this arbitration  procedure is intended to be
               the  exclusive  method of  resolving  any claim  relating  to the
               obligations set forth in this Agreement or otherwise  relating in
               any way to Employee's employment relationship with Companies.

          14.  Entire   Agreement.   This  Agreement  is  a  full  and  complete
               expression  of the  intent of the  parties  with  respect  to the
               subject  matter  of  this   Agreement.   No  other  agreement  or
               representation, express or implied, has been made by either party
               with respect to the subject matter of this Agreement.

          15.  Amendment. This Agreement may not be modified except by a written
               agreement  signed by both  Employee  and by a Vice  President  of

          16.  Governing Law. This Agreement shall be governed by, and construed
               in accordance  with, the laws of the State of California  without
               reference to the conflicts of law provisions thereof.

          17.  Severability.  In the event any provision of this Agreement shall
               finally be determined  to be unlawful,  such  provision  shall be
               deemed  to  be  severed  from  this  Agreement  and  every  other
               provision  of this  Agreement  shall  remain  in full  force  and
               effect.  If any one or more of the  provisions of this  Agreement
               shall for any reason be held to be excessively broad, it shall be
               construed,  by limiting and reducing it, so as to be  enforceable
               to the full extent possible under applicable law.

          18.  Assignment.  Employee  warrants  and  represents  that he has not
               assigned or in any way  transferred any right or claim related to
               the subject  matter of this  Agreement and that he will not allow
               or assist in such  transfer  or  assignment  in the  future.  Any
               purported assignment or transfer shall be deemed void ab initio.

          19.  No Admission. This Agreement shall not constitute an admission by
               any Released Party of any wrongful action or inaction whatsoever.

          20.  Voluntariness.  Employee agrees that this Agreement is understood
               by Employee and is voluntarily entered into by the Employee.

               receipt of the  amounts due under this  Agreement  in the form of
               Exhibit A. The last such designation received by Company prior to
               his death shall control any such payments.

          22.  Employee's  Right to Review  Agreement.  Employee has  twenty-two
               (22) days from the date of Employee's  receipt of this  Agreement
               to consider whether or not to sign this Agreement.

          23.  Effective Date. This Agreement shall not be effective until eight
               (8) days from the date of execution of this Agreement by Employee
               (the  "Effective  Date").  During  the seven days  following  his

          24.  Employee's  Right to  Consult  Counsel.  Employee  is  advised to

          25.  Parties in Interest. Except as expressly provided to the contrary
               herein,  this Agreement  shall be binding upon each successor to,
               and  assign  of, the  parties,  and inure to the  benefit of each
               permitted successor to, and assign of, the parties.

          26.  Waiver.  Employee  shall not be entitled to any other  separation

               forth below.

               (a)  "After Tax Equivalent" means, with respect to the value of a
                    benefit  under  a  Benefit  Plan  that  is  tax-free  or tax
                    deferred,  the amount necessary to replace the value of such
                    benefit  after the tax  effect on  Employee,  assuming a 50%
                    effective tax rate.  For example,  if Employee were not able
                    to receive a tax deferred  allocation of $1,000 in a Benefit
                    Plan that was a  defined  contribution  plan,  the After Tax
                    Equivalent  would  be  $2,000  payable  in  taxable  form to
                    Employee  (on the  assumption  that at least  $1,000  net of
                    taxes would be  generated  which  Employee  could  choose to
                    deposit in a  deferred  annuity).  Similarly,  the After Tax
                    Equivalent of a tax deferred  defined benefit future accrual
                    would be twice the lump sum present  value of the accrual at
                    the time the accrual would  otherwise  have  occurred  using
                    plan actuarial assumptions.

               (b)  "Applicable  Withholding"  means  the  sum of  (i)  required
                    Federal,  state and local payroll and income tax withholding
                    and  (ii)  withholdings  for   employee-side   contributions
                    pursuant to the terms of Benefit Plans.

               (c)  "Benefit  Plan"  means all of the  Unocal  employee  benefit
                    plans (as  defined in Section  3(3) of ERISA),  programs  or
                    fringe benefit  arrangements or payroll  practices in effect
                    at  the  Companies  on  October  14,  1999,  any  amendment,
                    modification,  restatement  or  successor  to same,  and any
                    other "employee benefit plans" as defined in Section 3(3) of
                    ERISA  or  fringe  benefit   programs   established  by  the
                    Companies during the term of Employee's employment described
                    in  Section  2(a) in which the Chief  Financial  Officer  of
                    Unocal is eligible to participate.

               (d)  "Confidential  Information"  has  the  meaning  assigned  by
                    Section 5.

               (e) "Effective Date" has the meaning assigned by Section 23.

               (f)  "LTIP"  means  the Long  Term  Incentive  Compensation  Plan
                    forming a part of the Unocal Management Incentive Program of
                    1998.

               (g)  "Non-Qualified Retirement Plans" means the Unocal Retirement
                    Supplementary  Compensation Plan and the Unocal Supplemental
                    Retirement Plan for Key Management Personnel.

               (h)  "RICP" means the Revised Incentive Compensation Plan forming
                    a  part  of  the  Unocal  Corporation  Management  Incentive
                    Program.

                                   APPENDIX A

A.   Employee's  benefits  under Section 4 of the Agreement  shall be a lump sum
     equal to the sum of the following:

     (1)  $1,575,000  (One  Million  Five  Hundred  and  Seventy-Five   Thousand
          Dollars), plus

     (2)  $75,000 (Seventy-Five Thousand Dollars), plus

     (3)  The sum of Employee's Revised Incentive Plan Awards for calendar years
          1998 and 1999 multiplied by 1.5 (one and one-half).plus

     (4)  An amount equal to $94,500

B.   The above  payment  shall be considered  full  satisfaction  of all rights,
     benefits and payments under Employee's  Unocal  Employment  Agreement dated
     July 28, 1998.

C.   Employee shall not be obligated to seek other  employment or take any other
     action by way of  mitigation of the amounts  payable to Employee  under any
     provisions of this Agreement.

D.   Certain Additional Payments by the Company may be due as follows:

     (1)  In the event it shall be determined  that any payment or  distribution
          by the  Company or its  affiliates  to or for the  benefit of Employee
          (whether paid or payable or distributed or  distributable  pursuant to
          the terms of this Agreement or otherwise but determined without regard
          to  any  additional  payments  required  under  this  Agreement),   (a
          "Payment")  would be subject to the excise tax imposed by Section 4999
          of the Internal  Revenue Code of 1986,  as amended (the "Code") or any
          interest or penalties  are  incurred by Employee  with respect to such
          excise tax (such  excise  tax,  together  with any such  interest  and
          penalties,  are  hereinafter  collectively  referred to as the "Excise
          Tax"),  then  Employee  shall be  entitled  to receive  an  additional
          payment (a "Gross-Up Payment") in an amount such that after payment by
          Employee of all taxes  (including  any interest or  penalties  imposed
          with respect such taxes),  including,  without limitation,  any income
          taxes (and any interest and  penalties  imposed with respect  thereto)
          and Excise Tax imposed upon the Gross-Up Payment,  Employee retains an
          amount of the  Gross-Up  Payment  equal to the Excise Tax imposed upon
          the  Payments.   Notwithstanding  the  foregoing  provisions  of  this
          Paragraph D(1), if it shall be determined that Employee is entitled to
          a Gross-Up  Payment,  but that the  Payments do not exceed 110% of the
          greatest amount (the "Reduced  Amount") that could be paid to Employee
          such that the  receipt of  payments  would not give rise to any Excise
          Tax,  then no  Gross-Up  Payment  shall  be made to  Employee  and the
          Payments, in the aggregate, shall be reduced to the Reduced Amount.

     (2)  Subject  to the  provisions  of  Paragraph  D(3),  all  determinations
          required to the made under this  Paragraph  D,  including  whether and
          when a Gross-Up  Payment is required  and the amount of such  Gross-Up
          Payment  and  the  assumptions  to be  utilized  in  arriving  at such
          determination,  shall  be made  by  Ernst  and  Young  or  such  other
          certified public accounting firm as may be designated by Employee (the
          "Accounting   Firm")   which   shall   provide   detailed   supporting
          calculations  both to the Company and Employee within 15 business days
          of the receipt of notice from  Employee that there has been a Payment,
          or such earlier time as is requested by the Company. In the event that
          the  Accounting  Firm is serving  as  accountant  or  auditor  for the
          individual,  entity or group effecting the Change of Control, Employee
          shall appoint another  nationally  recognized  accounting firm to make
          the  determinations  required  (which  accounting  firm  shall then be
          referred to as the Accounting Firm  hereunder).  All fees and expenses
          of the  Accounting  Firm  shall be borne  solely by the  Company.  Any
          Gross-Up Payment, as determined pursuant to this Paragraph D, shall be
          paid by the Company to Employee within five days of the receipt of the
          Accounting Firm's  determination.  Any determination by the Accounting
          firm shall be binding  upon the Company and  Employee.  As a result of
          the  uncertainty in the application of Section 4999 of the Code at the
          time of the initial determination by the Accounting Firm hereunder, it
          is possible  that Gross-Up  Payments  which will

                                       12
<PAGE>
          not  have   been   made  by  the   Company   should   have  been  made
          ("Underpayment"), consistent with the calculations required to be made
          hereunder. In the event that the Company exhausts itsremedies pursuant
          to  Paragraph  D(3) and  Employee  thereafter  is  required  to make a
          payment of any Excise Tax, the  Accounting  Firm shall  determine  the
          amount of the Underpayment that has occurred and any such Underpayment
          shall  be  promptly  paid  by the  Company  to or for the  benefit  of
          Employee.

     (3)  Employee  shall  notify  the  Company  in  writing of any claim by the
          Internal  Revenue  Service  that,  if  successful,  would  require the
          payment by the  Company of the  Gross-Up  Payment.  Such  notification
          shall be given as soon as  practicable  but no later than 10  business
          days after  Employee  is  informed  in writing of such claim and shall
          apprise  the Company of the nature of such claim and the date on which
          such claims is requested to be paid.  The Employee  shall not pay such
          claim prior to the expiration of the 30-day period  following the date
          on which it gives such notice to the Company (or such  shorter  period
          ending on the date that any  payment  of taxes  with  respect  to such
          claim is due).  If the Company  notifies  Employee in writing prior to
          the  expiration  of such period that it desires to contest such claim,
          Employee shall:

          (i)  give the  Company any  information  reasonably  requested  by the
               Company relating t such claim;

          (ii) take such action in connection  with contesting such claim as the
               Company  shall  reasonably  request in writing from time to time,
               including,  without  limitation,  accepting legal  representation
               with respect to such claim by an attorney  reasonably selected by
               the Company;

          (iii)cooperate with the Company in good faith in order  effectively to
               contest such claim; and

          (iv) permit the Company to participate in any proceedings  relating to
               such claim;

          provided,  however,  that the Company  shall bear and pay directly all
          costs and  expenses  (including  additional  interest  and  penalties)
          incurred in connection  with such contest and shall indemnify and hold
          Employee harmless, on an after-tax basis, for any Excise Tax or income
          tax (including interest and penalties with respect thereto) imposed as
          a result of such  representations  and payment of costs and  expenses.
          Without limitation on the foregoing provisions of this Paragraph D(3),
          the Company shall  control all  proceedings  taken in connection  with
          such contest and, at its sole option, may pursue or forego any and all
          administrative appeals, proceedings, hearings and conferences with the
          taxing authority in respect of such claim and may, at its sole option,
          either direct  Employee to pay the tax claimed and sue for a refund or
          contest the claim in any  permissible  manner,  and Employee agrees to
          prosecute such contest to a  determination  before any  administrative
          tribunal,  in a  court  of  initial  jurisdiction  and in one or  more
          appellate courts, as the Company shall determine;  provided,  however,
          that if the Company  directs  Employee to pay such claim and sue for a
          refund,  the  Company  shall  advance  the  amount of such  payment to
          Employee,  on an  interest-free  basis  and shall  indemnify  and hold
          Employee  harmless,  on an  after-tax  basis,  from any  Excise Tax or
          income tax  (including  interest or penalties  with  respect  thereto)
          imposed  with  respect  to the such  advance  or with  respect  to any
          imputed  income with respect to taxes for the taxable year of Employee
          with  respect to which such  contested  amount is claimed to be due is
          limited solely to such contested  amount.  Furthermore,  the Company's
          control of the  contest  shall be limited  to issues  with  respect to
          which a Gross-Up payment would be payable hereunder and Employee shall
          be entitled to settle or contest,  as the case may be, any other issue
          raised by the Internal Revenue Service or any other taxing authority.

     (4)  If, after the receipt by Employee of an amount advanced by the Company
          pursuant to Paragraph D(3),  Employee  becomes entitled to receive any
          refund with  respect to such  claim,  Employee  shall  (subject to the
          Company's employing with the requirements of Paragraph D) promptly pay
          to the Company the amount of such refund  (together  with any interest
          paid or credited  thereon after taxes applicable  thereto).  If, after
          the  receipt by Employee  of an amount  advanced  by the Company  with

                                       13
<PAGE>
          respect to such claim and the  Company  does not  notify  Employee  in
          writing of its intent to contest  such  denial of refund  prior to the
          expiration  of 30 days after  such  determination,  then such  advance
          shall be  forgiven  and shall  not be  required  to be repaid  and the
          amount of such advance shall offset, to the extent thereof, the amount
          of Gross-Up Payment required to be paid.
