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  1997  Annual
     Report on Form 10-K.

     Results for the nine months ended  September 30, 1998, are not  necessarily
     indicative of future financial results.

     Certain items in the prior year financial statements have been reclassified
     to conform to the 1998 presentation.

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

(3)  Other Financial Information

     Sales and operating revenues are derived principally from the sale of crude
     oil, natural gas, natural gas liquids, geothermal steam, specialty minerals
     and nitrogen-based  agricultural  products produced by the company.  During
     the  third  quarters  of 1998 and 1997,  approximately  40  percent  and 29
     percent,   respectively,   of  total  sales  and  operating  revenues  were
     attributed  to the resale of purchased  crude oil,  natural gas and natural
     gas liquids  produced by others,  that the company  purchased in connection
     with its  trading  and  marketing  activities.  For the nine  months  ended
     September  30, 1998 and 1997,  the  percentage of total sales and operating
     revenues  attributed to the resale of purchased crude oil,  natural gas and
     natural gas liquids produced by others was  approximately 34 percent and 28
     percent, respectively.  Related purchase costs are classified as expense in
     the crude oil and product purchases  category of the consolidated  earnings
     statement.

     Capitalized  interest  totaled $5  million  and $10  million  for the third
     quarters  of 1998 and  1997,  respectively.  Capitalized  interest  was $22
     million  and $26  million  for the  first  nine  months  of 1998 and  1997,
     respectively.

 (4) Income Taxes

     Taxes on earnings from  continuing  operations  totaled $39 million for the
     third  quarter of 1998  versus a net tax  benefit of $174  million  for the
     comparable  period in 1997.  For the first  nine  months of 1998,  taxes on
     earnings  from  continuing  operations  were $177  million  compared to $68
     million for the same period in 1997.

     The  effective  income  tax rate for the first  nine  months of 1998 was 53
     percent  versus  12  percent  for the  same  period  in  1997.  The  higher
     year-to-date  effective  tax rate  for 1998  reflects  an  increase  in the
     foreign-versus-domestic  earnings  mix and tax  adjustments  related to the
     appreciation  of the Thai baht.  The first nine months and third quarter of
     1997  reflect $182 million in deferred  income tax  benefits:  $114 million
     related to a reassessment  of Unocal's  exposure for pending federal income
     tax  appeals  and  $68  million  related  to the  currency  devaluation  in
     Thailand.

(5)  Comprehensive Income

     Effective  for the  first  quarter  1998,  the  company  adopted  Financial
     Accounting  Standard  No.  130,  "Reporting  Comprehensive  Income",  which
     establishes standards for reporting and displaying comprehensive income and
     its  components  in a  full  set of  financial  statements.  The  company's
     comprehensive earnings were as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(Unaudited)

     Not included in the computation of diluted EPS were options  outstanding at
     September 30, 1998 to purchase  approximately  5.4 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 the
     common  shares.  The exercise  prices of these options range from $36.88 to
     $51.01 per share and they expire in 2007 and 2008.

(7)  Long Term Debt and Credit Agreements

     Financing  activities  during  the  third  quarter  of  1998  included  the
     retirement of $65 million in medium-term  notes.  In addition,  the company
     increased  outstanding  commercial  paper  borrowings  by $12  million to a
     balance of $468 million at September 30, 1998.

 (8)  Financial Instruments

     The fair values of the  company's  financial  instruments  at September 30,
     1998 are described below:

     In August,  the  company's  Canadian  subsidiary  repaid $250 million in US
     dollar denominated loans and terminated related currency swap agreements of
     $162 million.  Unocal also terminated $162  million of offsetting  currency
     swap agreements in August.  At September 30, 1998, an $88 million  currency
     swap agreement  remained  outstanding on the Canadian  subsidiary's  books.
     This  currency swap  agreement  was offset by an $88 million  currency swap
     agreement  on  Unocal's  books.  The net fair  value of the  currency  swap
     agreements outstanding at September 30 was approximately zero.

     On October 1, Unocal and the company's Canadian  subsidiary  terminated the
     remaining  $88 million  outstanding  currency  swap  agreements.  All costs
     associated  with termination of the aggregate $250 million of currency swap
     agreements were recorded in the third quarter and were immaterial.

     At  September  30,  1998,  the  company had two  foreign  currency  forward
     exchange  contracts  outstanding  to purchase Thai baht.  The contracts are
     designed to hedge the  company's  foreign  currency  exposure for estimated
     baht income tax payments scheduled to be paid to the government of Thailand
     in May 1999. The first contract calls for the company to pay  approximately
     $19 million in exchange  for 800 million  baht at maturity on May 25, 1999.
     The second contract calls for the company to pay  approximately $12 million
     in exchange  for 500 million  baht at  maturity on May 25,  1999.  The fair
     values  of  the contracts  at September 30, 1998 were immaterial.  The fair
     values  approximated  the net  gains that  would have been  realized if the
     contracts  had  been  closed out at  September 30  and  were  estimated  by
     comparing  the contract rates to the forward rates in effect at the balance
     sheet date.

     The  estimated  fair  value of the  company's  long-term  debt  was  $2,607
     million.  The fair values of  debt instruments were based on the discounted
     amount of future cash outflows  using the rates offered  to the company for
     debt with similar remaining maturuties. 

     The  estimated  fair  value  of  the  mandatorily  redeemable   convertible
     preferred  securities of  the company's subsidiary  trust was $546 million.
     The fair value of the preferred securities was based on the trading  prices
     of the preferred securities on September 30, 1998.

(9)  Accrued Abandonment, Restoration and Environmental Liabilities

     At  September  30,  1998,  the  company  had $452  million  accrued for the
     estimated   future  costs  to  abandon  and  remove  wells  and  production
     facilities.  The total costs for abandonments are predominately accrued for
     on a  units-of-production  basis and are estimated to be approximately $629
     million.  This  estimate  was derived in large part from  abandonment  cost
     studies  performed  by an  independent  firm and is used to  calculate  the
     amount to be amortized. The company's reserve for environmental remediation
     obligations  at  September  30, 1998 totaled  $292  million,  of which $132
     million was included in current liabilities.

(10) 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 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
     and are 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, if liability  is 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, and the fact that the company is usually
     just one of a number of companies identified as a PRP.

     As disclosed in note 9, at September 30, 1998, the company had accrued $292
     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 possibly could incur additional  remediation
     costs aggregating approximately $220 million.

     Tax matters - In December 1994,  the company  received a Notice of Proposed
     Deficiency  (Notice) from the Internal Revenue Service (IRS) related to the
     years 1985  through  1987. A material  amount of tax and interest  would be
     payable  if the IRS were  ultimately  able to  prevail  on the  significant
     issues  described  in the Notice.  In February  1995,  the company  filed a
     protest of the proposed tax deficiency with the Appeals section of the IRS.
     Discussions  with the  Appeals  Officer  are  complete,  and it now appears
     unlikely  that any  issues  raised in the  Notice  will  proceed  to either
     litigation  or  mediation as a settlement  has been  reached.  The proposed
     settlement  for all open taxable years  preceding  1988 was received by the
     Joint Committee on Taxation of the U.S. Congress in June 1998, and requires
     its approval.  The company  expects this matter to be concluded in 1998 and
     believes it is ultimately  entitled to a refund for  overpayment  of tax or
     interest.

     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  interfered  with Bridas' rights under
     agreements  with the government of  Turkmenistan to develop a gas field and
     transport the gas to Pakistan as well as 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 judgment and dismissed the action. It is not
     known  whether  Bridas  will  move for a new trial or file an appeal of the
     court's ruling.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
(Unaudited)

     The company also has certain other  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.

(12)  Other Matters

      In August 1998, Unocal entered into a settlement agreement with certain of
      its insurers for the  recovery of certain past  environmental  remediation
      claims.  Under the terms of the  agreement,  each liable  insurer who is a
      party to the agreement must place its share of the  negotiated  settlement
      amount of approximately $71 million into an escrow account by November 16,
      1998. The final settlement  amount will not be known until that date as it
      is contingent upon certain conditions, including each of the participating
      insurers'  ability and intent to abide by the  agreement's  terms.  Unocal
      expects to collect  substantially all of the negotiated settlement amount,
      none of which had been recorded at September 30, 1998.

</TABLE>

Third Quarter 1998 vs. Third Quarter 1997

Adjusted after-tax earnings from continuing operations decreased $90 million for
the period.  Lower  worldwide  commodity  prices for crude oil,  natural gas and
fertilizer  products and increased dry hole costs were the primary  contributors
to the depressed earnings.  Compared to 1997, average worldwide sales prices for
crude oil and natural gas declined 30 percent and 12 percent,  respectively. The
increase in dry hole costs reflected the company's expanded exploration program.
These negative  factors were partially offset by increased crude oil liftings in
Indonesia, new crude oil production in Yemen and Azerbaijan,  higher natural gas
production in Indonesia,  lower depreciation and depletion expense and increased
geothermal power generation and related sales volumes in Indonesia.

Year-to-date 1998 vs. Year-to-date 1997

Depressed  worldwide crude oil, natural gas and fertilizer product sales prices,
lower  domestic  natural  gas  production  volumes and higher dry hole costs and
exploration  expenses as a result of the company's expanded  exploration program
were the  primary  causes  of the 64  percent  decrease  in  adjusted  after-tax
earnings for the period.  Compared to 1997,  average  worldwide sales prices for
crude oil and  natural gas  declined  32 percent  and 11 percent,  respectively.
Positive  factors  mitigating the lower earnings  included  increased  crude oil
liftings  in  Indonesia,  increased  natural  gas  production  in  Thailand  and
Indonesia,   lower  domestic  depreciation  and  depletion  expense,   increased
geothermal  power  generation  and related  sales  volumes in  Indonesia,  lower
maintenance  related costs at the Kenai,  Alaska fertilizer plant due to a plant
turn-around  in 1997,  higher export sales  volumes of  fertilizer  products and
higher  earnings  and  dividends  from a  petroleum  industry  mutual  insurance
company.

EXPLORATION AND PRODUCTION

Exploration and Production  involves the exploration for and production of crude
oil and natural gas.

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

</TABLE>

Third Quarter 1998 vs. Third Quarter 1997

Adjusted after-tax earnings decreased $59 million primarily due to lower average
United States crude oil and natural gas sales  prices.  Crude oil prices fell 28
percent, or $4.39 per barrel,  while natural gas prices fell 18 percent, or $.41
per thousand cubic feet.  Increased dry hole costs and exploration  expense as a
result of increased exploration activity in the Gulf of Mexico and lower natural
gas production volumes for Spirit Energy 76 as a result of storms in the Gulf of
Mexico also negatively affected earnings for the period. However, these negative
factors were  partially  offset by a 7 percent  increase in crude oil production
and lower depreciation and depletion expense for Spirit Energy 76.

Year-to-date 1998 vs. Year-to-date 1997

Adjusted  after-tax  earnings  decreased  85  percent  principally  due to lower
average  United  States crude oil and natural gas prices,  higher dry hole costs
and  exploration  expense as a result of  increased  Gulf of Mexico  exploration
activity and lower natural gas production  volumes.  The average sales price for
crude oil  decreased 33 percent,  or $5.72 per barrel,  while the average  sales
price for natural gas  decreased 12 percent,  or $.28 per  thousand  cubic feet.
Natural gas production declined by 9 percent, or 86 million cubic feet daily. In
general, the production decrease is attributable to natural production declines.
These negative  factors were partially  offset by a decrease in depreciation and
depletion expense.

International  - The company's  international  operations  include the company's
foreign  exploration  and  production  activities  and  exploration   activities
performed by the company's New Ventures group.

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

In April 1998, the company  received shares of common stock and debt of Tarragon
Oil and Gas Limited  (Tarragon)  valued at  approximately  $212  million for the
exchange of its Alberta,  Canada exploration and production assets. In the third
quarter  1998,  the company  converted  this debt and common  stock to cash as a
result of a tender  offer  from  USX-Marathon  for the  purchase  of  Tarragon's
outstanding   common  stock.   The  total  after-tax  gain  recorded  for  these
transactions was $102 million (included in special items).

Third Quarter 1998 vs. Third Quarter 1997

During the third quarter of 1998, earnings decreased 59 percent, or $36 million.
The primary factors affecting  earnings were lower average  international  crude
oil and natural gas prices,  lower Thailand and Canada crude oil and natural gas
production,  an increase in dry hole costs and higher  current taxes in Thailand
related  to  foreign  currency  fluctuations.  International  crude  oil  prices
declined  31  percent,  or $5.41 per barrel,  for the period  while  natural gas
prices  declined  to $2.23 from $2.39 per  thousand  cubic  feet,  or 7 percent.
However,  these negative  factors were partially  offset by increased  crude oil
liftings and natural gas production in Indonesia and new crude oil production in
Yemen and Azerbaijan in 1998.

Year-to-date 1998 vs. Year-to-date 1997

Lower  average   international  crude  oil  and  natural  gas  prices  primarily
contributed  to the 52  percent  drop in  adjusted  after-tax  earnings  for the
period.  In 1998,  average  international  crude oil prices  declined  $5.93 per
barrel,  or 32 percent,  and average  international  natural gas prices declined
$.24 per thousand cubic feet, or 10 percent. Also contributing to the decline in
adjusted  after-tax  earnings were higher  current taxes in Thailand  related to
foreign currency fluctuations, increased dry hole costs and exploration expenses
and foreign  exchange losses in Thailand and Indonesia.  These negative  factors
were offset by higher crude oil liftings in Indonesia and increased  natural gas
production volumes in Indonesia and Thailand.

GLOBAL TRADE

The Global Trade group  handles  substantially  all of the  company's  worldwide
crude oil, condensate, natural gas and natural gas liquids marketing and trading
activities.  Global Trade also purchases  crude oil,  condensate and natural gas
from the company's joint venture partners, royalty owners and other unaffiliated
oil and gas producers for resale.

Global  Trade's  after-tax  earnings  during the third quarters of 1998 and 1997
were $3 million and $2 million,  respectively.  After-tax earnings for the first
nine months of 1998 and 1997 were $13 million in each period.

GEOTHERMAL AND POWER OPERATIONS

</TABLE>

In 1997,  after-tax earnings reflected the sale of the company's  Illinois-based
Unocal  Hydrocarbon  Sales  business unit and the  restructuring  of the UNO-VEN
partnership.  These transactions  generated gains (included in special items) of
$41 million and $39 million, respectively.


Third Quarter 1998 vs. Third Quarter 1997

Adjusted  after-tax  earnings  declined due  primarily to lower  realized  sales
prices for export  fertilizer  products,  lower  margins on  specialty  graphite
products  sales,  and lower  realized  sales  prices  for both  lanthanides  and
molybdenum  products.  These negative factors were partially offset by increased
worldwide fertilizer products sales volumes,  lower maintenance related expenses
at the company's  Kenai,  Alaska  fertilizer  plant due to a plant turnaround in
1997 and tax related adjustments in 1998.

Year-to-date 1998 vs. Year-to-date 1997

Adjusted  after-tax earnings fell 19 percent primarily due to lower sales prices
for export  and  domestic  fertilizer  products,  decreased  sales  volumes  for
domestic fertilizer  products,  lower molybdenum  production and losses from the
company's lanthanides operation due to the temporary shutdown of the separations
plant and wastewater pipeline at its Mountain Pass, California, mining facility.
The negative impact of these factors was partially  offset by higher  fertilizer
product  export  sales  volumes,  lower  maintenance  related  expenses  at  the
company's Kenai,  Alaska  fertilizer plant due to a plant turnaround in 1997 and
higher earnings from the company's Brazilian affiliate.


CORPORATE AND UNALLOCATED

Corporate and Unallocated  expense  includes  general  corporate  overhead,  the
non-exploration  and production related activities of the New Ventures group and
other unallocated costs. Net interest expense represents  interest expense,  net
of interest income and capitalized interest.

</TABLE>
For the nine months ended  September 30, 1998, the Other  category  included the
benefit of an $11 million  insurance  settlement,  which was included in special
items.  In the third  quarter of 1997,  a $114  million tax benefit was recorded
related to a reassessment  of the company's  exposure for pending federal income
tax appeals, which was also included in special items.

Third Quarter 1998 vs. Third Quarter 1997

Higher  administrative and general and net interest expense due to a higher debt
level  primarily  contributed  to the  13  percent  increase  in  Corporate  and
Unallocated  expense for the period.  These  increased  expenses were  partially
offset by increased earnings from an insurance company subsidiary.

Year-to-date 1998 vs. Year-to-date 1997

Adjusted after-tax  expenses  decreased 21 percent  principally due to lower New
Ventures -  non-exploration  and  production  expenses  and higher  earnings and
dividends from a petroleum  industry  mutual  insurance  company in 1998.  These
positive   factors  were   slightly   offset  by  an  increase  in  general  and
administrative expense.

FINANCIAL CONDITION AND CAPITAL EXPENDITURES

For the  first  nine  months  of 1998,  cash  flow  from  operating  activities,
including working capital changes, was $711 million,  compared with $736 million
in 1997.  The decrease was primarily  attributable  to the effect of lower crude
oil, natural gas and fertilizer  product prices and increased  receivable levels
in Indonesia. Those negative factors were partially offset by an increase in the
accrual of current taxes and capital  accruals  related to the August lease sale
conducted by the U.S. Minerals Management Service.

Proceeds  from asset sales for the first nine  months of 1998 were $299  million
and  consisted  of  $262  million  from  the  sale  of  the  company's  Tarragon
investment, $28 million from the sale of miscellaneous  international,  domestic
and real estate properties and $9 million related to the partial collection of a
note received on the sale of Unocal Hydrocarbon Sales in 1997.

Capital  expenditures  for the first nine months of 1998 totaled  $1,248 million
compared to $953  million in the first nine  months of 1997.  The  increase  was
primarily due to increased  drilling  activities and lease  acquisitions  in the
Gulf of Mexico partially offset by lower geothermal expenditures. The first nine
months of 1997  included $49 million of capital  expenditures  for  discontinued
operations.

The company expects its 1998 capital  spending to total about $1.65 billion,  up
from an earlier  forecast of $1.5 billion.  The increase in capital  spending is
expected to be funded from a combination  of asset sales  proceeds and increased
debt.

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

The  company's  long-term  debt was $2,423  million at September  30,  1998,  an
increase of $254  million from the year-end  1997 level of $2,169  million.  The
debt-to-total  capitalization  ratio  increased to 46 percent from 42 percent at
year-end 1997. 

ENVIRONMENTAL MATTERS

At September 30, 1998,  the  company's  reserves for  environmental  remediation
obligations  totaled $292 million, of which $132 million was included in current
liabilities (see note 9 to the consolidated  financial  statements).  During the
third quarter, cash payments of $19 million were applied against the reserve and
an additional  $18 million in  liabilities  were  recorded.  The  additional $18
million in reserves  were  primarily  for  estimated  cleanup  costs for various
company facilities where the company's operations have been closed or shut down.
The company also estimates that it possibly could incur  additional  remediation
costs  aggregating  approximately  $220  million as  discussed in note 10 to the
consolidated  financial  statements.  The company's total environmental  reserve
amount is grouped into the following five categories:

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 in future revenues,  earnings,  cash flows,  capital  expenditures,
assets,  liabilities  and  other  financial  items  and of  future  levels of or
increases 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.

Although  Asia  continues  to struggle  with the  economic  crisis  gripping the
region,  the company still  remains  optimistic  about its  excellent  long-term
growth opportunities in Asia. In Thailand and Indonesia,  the company is working
closely with host governments and business associates to help them through these
difficult  economic  times.  As of September 30, 1998, the company's  geothermal
operations  in Indonesia had a gross  receivable  balance of  approximately  $79
million,  most of which was for steam sales from the Salak field.  Approximately
$26 million is due by the end of November 1998, of which $17 million  represents
a shortfall in payments for March  through July 1998 steam  deliveries to Gunung
Salak electric  generating Units 1, 2 and 3. Partial payments have been received
on a timely basis. The remaining balance is payable over the next several years.
The  company  continues  to engage in  discussions  with  Indonesian  government
entities to explore potential ways to resolve the shortfall issue.

Worldwide  energy prices remain  depressed and the company expects this trend to
continue to  negatively  impact 1998  financial  results.  However,  the company
remains confident that it is well positioned to weather this low commodity price
environment.

The company strives to create value for stockholders. To achieve this objective,
the  company is  focused on finding  and  developing  new  high-return  business
opportunities in a low-cost manner.  In 1998,  Spirit Energy 76 achieved a total
of 29 new  commercial  successes  in the onshore  Louisiana,  the Gulf of Mexico
shelf and deepwater,  the Permian Basin and East Texas areas.  Deepwater Gulf of
Mexico  exploration  drilling is  currently  under way on the Mad Dog and Mirage
prospects.  In August,  Spirit Energy was the apparent high bidder for interests
in 62 additional blocks in the deepwater Gulf of Mexico lease sale.

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

In  Indonesia,  positive  results from the first four wells in the Seno prospect
will allow the company to complete a  development  plan which  should  result in
first production during 2001. Current plans also call for drilling on the nearby
Janaka prospect.

YEAR 2000

The company is actively  addressing  the Year 2000 (Y2K) issue   throughout  its
operating and office environments. 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 computer applications could result in system failures with
possible material adverse effects on the company's  operations at the year 2000.
The company has appointed a program  manager and has assembled  various teams of
professionals to identify,  assess, correct and test these software applications
as well as its embedded systems. In addition,  the company has contracted with a
systems consulting firm to assist with the assessment, correction and testing of
the  company's  internal  systems as well as to assess its system  relationships
with vendors, suppliers, customers and other outside parties.

Initiation of the company's Y2K project work began in July 1996. A  company-wide
initial  awareness  campaign  was  completed  in June 1998.  Identification  and
assessment  phases of the  project  are well  underway.  The  company  is in the
process of preparing  business  contingency  and recovery plans for its "mission
critical" systems,  applications and processes. These systems,  applications and
processes,  if  not  operable,   could  materially  adversely  impact  revenues,
operations,  safety or the environment.  The company's Y2K project work includes
the updating of these plans to address material Y2K issues.

The  company's  Y2K  efforts  can be  divided  into  three  general  categories:
Information  Technology  (IT)  systems  and  applications,  embedded  systems in
process controls,  and critical business partners. As of September 30, 1998, the
company  had  completed  95  percent  of the  inventory  and 85  percent  of the
assessment  of Y2K  problems  in the  "IT  systems  and  applications"  and  the
"embedded  systems in  process  controls"  categories.  In the "IT  systems  and
applications"  category,  detailed  planning  to  correct  or  work  around  the
anticipated problems is 80 percent complete and corrective action and testing is
20 percent complete.  In the "embedded  systems in process  controls"  category,
detailed  planning  to  correct  or work  around  the  anticipated  problems  is
approximately 50 percent complete and the repair and testing of these systems is
20 percent complete.  In the "critical business partners" category,  the company
is  currently  assessing  its  exposure to problems  with  business  partner Y2K
readiness.  Although some critical  business  partners have been  identified and
contacted, comprehensive effort in this area will begin in the fourth quarter of
1998.

The following schedule sets forth  the company's overall estimated timetable for
achieving Year 2000 readiness:

Project Phases                                      Expected Completion Dates
- --------------                                      -------------------------

Continuous System Review                             Ongoing - through fourth 
                                                       quarter 1999

The company  currently  estimates the  expenditures on the preceding Y2K project
phases  to  approximate  $30 to  $35  million.  These  expenditures  will  occur
throughout   1998  and  1999.   Expenditures  as  of  September  30,  1998  were
approximately $5 million.  

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  principle  areas of risk are thought to be oil and gas  production  control
systems,  other  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 there will not be a delay in, or increased  costs
associated  with the  implementation  of such  changes or that such changes will
prove 100 percent effective in resolving all Y2K related issues.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Market risk generally  represents the risk that losses may occur in the value 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  contracts,  subject  to  company  controls  and
monitoring  requirements.  The  following  discussion  and  analysis  focuses on
significant changes in the company's position regarding these risk factors since
year end 1997.

Interest  Rate Risk - The  company's  primary  market  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. Other instruments, such as interest
rate swaps,  options,  floors,  caps or collars may also be used  depending upon
market  conditions.  During the first nine months of 1998, the company increased
its outstanding  debt level  (excluding  capital leases) by  approximately  $255
million  to $2,423  million  from its  year-end  1997  level of $2,168  million,
primarily  through the sale of two new debt  issues.  On May 6, 1998,  Union Oil
issued  $100  million  of 6 1/2 % notes due May 1, 2008 and $200  million of 7 %
debentures due May 1, 2028, in each case guaranteed by Unocal. Proceeds from the
sale  were  used to  retire  $110  million  Deutsche  Mark  bonds  and to reduce
outstanding   commercial  paper   borrowings.   The  company  also  reduced  its
outstanding medium term notes in the third quarter of 1998. The increase in debt
is  principally  due to increased  cash  requirements  resulting from lower than
anticipated  commodity  prices in 1998. The following  table provides  principal
amounts,  related  weighted  average  interest  rates,  and fair  values for the
company's  outstanding debt obligations by expected  maturity dates at September
30, 1998 and  constitutes a forward  looking  statement.  The company expects to
refinance  its debt  obligations  that are  scheduled to mature during the years
1998 to 2002.  Circumstances  could arise which may cause interest rates and the
timing  and  amounts  of  actual  cash  flows  to  differ  materially  from  the
projections.

- ------------------------------------------------------------------------------------------------------------------------------------
</TABLE>
Foreign  exchange rate risk - Where  warranted,  the company enters into various
foreign  currency  contracts,  such as forward exchange  contracts,  options and
currency  swaps, to manage its exposure to foreign  currency  exchange rates. At
September  30,  1998,  the  company had two foreign  currency  forward  exchange
contracts outstanding to purchase Thai baht. The contracts are designed to hedge
the company's  foreign currency  exposure for estimated baht income tax payments
scheduled  to be paid to the  government  of  Thailand  in May  1999.  The first
contract calls for the company to pay  approximately $19 million in exchange for
800 million baht at maturity on May 25, 1999. The second  contract calls for the
company to pay  approximately  $12 million in exchange  for 500 million  baht at
maturity on May 25, 1999.  The fair value of the contracts at September 30, 1998
was  approximately  $609  thousand and $172 thousand  respectively.  Fair values
approximate  the net gains that would have been  realized if the  contracts  had
been closed out at  September 30 and are  estimated  by  comparing  the contract
rates to the forward rates in effect at the balance sheet date.

As a result of the sale of the company's  holdings in Tarragon  common stock and
debentures, the company's Canadian subsidiary repaid $250 million in outstanding
loans  (denominated in US dollars) and terminated its corresponding $250 million
currency swap agreements in August and October 1998.  Unocal also terminated its
$250 million  off-setting  currency swap  agreements in August and October 1998.
The  Canadian  subsidiary's  swap  agreements  had the  effect of  changing  the
subsidiary's  US dollar  denominated  borrowings  into its  functional  Canadian
currency.  The  purpose  of the swap  agreements  was to limit the  subsidiary's
exposure to currency  exchange  gains and losses and to allow Unocal to maintain
the underlying debt in US dollars for consolidated financial reporting purposes.
Amounts  related to the swap  agreements  terminated  in October were accrued in
September accounts.

Commodity  price  risk  - The  company  uses  hydrocarbon  derivative  financial
instruments,  such as futures  contracts or options with maturities of 18 months
or less,  to mitigate  its exposure to  fluctuations  in  hydrocarbon  commodity
prices. On occasion,  the company may enter into forward sales. The company also
takes  pricing  positions  in  hydrocarbon   derivative  financial   instruments
(primarily  exchange regulated futures and option contracts) subject to internal
policy  limitations.  The  company  monitors  its trading  activities  to ensure
compliance with its policies.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. (CONTINUED)

The  company  uses a value at risk model to assess the market  risk of its price
sensitive hydrocarbon derivative financial instruments. Value at risk represents
the potential loss in fair value the company would experience on its hydrocarbon
derivative financial instruments, using calculated volatilities and correlations
over a specified  time  period  with a given  confidence  level.  The  company's
calculation  model is based on historical data and uses a one-week time interval
and a 95 percent  confidence level. Based upon the company's model, the value at
risk associated  with  hydrocarbon  derivative  financial  instruments  held for
trading  purposes was  approximately $7 million at September 30, 1998. The value
at risk associated with hydrocarbon  derivative  financial  instruments held for
purposes other than trading was approximately $8 million at September 30, 1998.

         5,288,393 for claims for the  composition  of  reformulated  gasolines,
         with the result that the patent is valid and enforceable.  On September

ITEM 1.   LEGAL PROCEEDINGS (CONTINUED)

(6)      With reference to the  investigation by the U.S.  Department of Justice
         and the related private lawsuit under the federal False Claims Act with
         respect to the alleged  underpayment of royalties on crude oil produced
         from federal and Indian land leases, the company has recently been made
         aware that it has been named as a defendant in two separate proceedings
         brought under the False Claims Act, alleging  underpayment of royalties
         since the mid-1980's on natural gas production  from federal and Indian
         land leases. The first action, United States, ex rel. Harrold E. (Gene)
                                        ----------------------------------------
         Wright v. Amerada  Hess,  et al. (U.S.  District  Court for the Eastern
         --------------------------------
         District of Texas),  was filed in August  1996  against the company and
         130 other energy  industry  companies  and seeks  damages of $3 billion
         from all defendants.  The second action, United States, ex rel. Jack J.
                                                  ------------------------------
         Grynberg v. Unocal (U.S.  District  Court for the District of Wyoming),
         ------------------  
         was filed in  September  1997 as one of 77 separate  cases filed by Mr.
         Grynberg  and seeks  damages of  approximately  $200  million  from the
         company.  To date,  the U.S.  Department  of Justice has not elected to
         intervene in either  proceeding.  The company  believes the allegations
         are without merit and intends to vigorously defend both cases.

(7)      With  reference  to  the   preliminary   determinations   of  underpaid
         royalties,  described in Paragraph (10) of Item 3 of the 1997 Form 10-K
         and in  Paragraph  (4) of Item 1 of Part II of the First  Quarter  1998
         Form 10-Q, the total amount,  including  interest,  claimed by the U.S.
         Department of Interior,  Minerals Management Service,  has been reduced
         to approximately $35 million.

(8)      With reference to the matters involving the Mountain Pass,  California,
         lanthanide  facility  of  the  company's  Molycorp,   Inc.  (Molycorp),
         subsidiary,  described  in  Paragraph  (14) of Item 3 of the 1997  Form
         10-K,  in Paragraph  (5) of Item 1 of Part II of the First Quarter 1998
         Form  10-Q  and in  Paragraph  (4) of Item 1 of  Part II of the  Second
         Quarter  1998 Form  10-Q,  in August  1998 the  Office of the  District
         Attorney of San Bernardino  County,  California,  advised Molycorp that
         settlement  discussions  were  suspended,  that a grand  jury  would be
         convened  to inquire  into the matter and that two  Molycorp  employees
         also have been named as targets.  To  Molycorp's  knowledge,  the grand
         jury has not yet been convened. Settlement discussions were reopened in
         October 1998.

         In the District  Attorney's  civil action captioned People of the State
                                                             -------------------
         of California v. Molycorp,  Inc.,  alleging  violations of California's
         --------------------------------
         Proposition 65 law, on September 10, 1998, Molycorp filed its answer to
         the complaint.

(9)      In the  lawsuit  captioned  State of Arizona  v.  Union Oil  Company of
                                     -------------------------------------------
         California,  described  in  Paragraph  (16) of Item 3 of the 1997  Form
         ----------
         10-K,  the state has  informed  the  company  that it is seeking  civil
         penalties in excess of $1.5  million,  as well as other  payments.  The
         company intends to vigorously contest the state's allegations.

ITEM 2.   CHANGES IN SECURITIES

During the third quarter of 1998, Unocal awarded 4,213 restricted stock units to
nonemployee  directors  pursuant  to  the  terms  of  the  company's  Directors'
Restricted  Stock Units Plan. The 4,213 units were awarded (1) in  consideration
of the prior  election by each of the  nonemployee  directors  to defer all or a
portion of his or her cash fees and (2) upon the credit of dividend  equivalents
upon  units  previously  awarded.  The  units  were  not  registered  under  the
Securities  Act of 1933 (the Act) in reliance  upon the  exemption  contained in
Section 4(2) of the Act for  transactions  by an issuer not involving any public
offering.  The units are paid out in an equal number of shares of Unocal  common
stock at the end of a deferral period.
