                   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  1996  Annual
     Report on Form 10-K (as amended).

     Results  for the six  months  ended  June  30,  1997,  are not  necessarily
     indicative of future financial results.

     Certain items in the prior year financial statements have been reclassified
     to conform to the 1997 presentation.

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

(3)  Discontinued Operations

     On March 31, 1997, the company sold its West Coast refining,  marketing and
     transportation  assets to Tosco  Corporation  (Tosco).  In addition to cash
     proceeds of $1.4 billion,  the company received  14,092,482 shares of Tosco
     common  stock valued at $397  million.  The value of the stock was based on
     the  average of the high and low market  prices of the Tosco  stock for the
     last 10 trading  days prior to the sale.  On May 8, 1997,  the company sold
     the stock back to Tosco for $394 million (net of expenses).

     During the first six months of 1997,  the company  recorded  an  additional
     loss on  disposal of $44 million  (net of a $27 million tax  benefit).  The
     additional  provision was required  primarily due to adjustments in closing
     inventory amounts and higher than anticipated  termination costs.  Included
     in the $44 million  amount is a favorable  adjustment of $6 million (net of
     $4 million tax) related to a lower than expected  first  quarter  operating
     loss.

     The consolidated  earnings statement reflects the results for the refining,
     marketing and transportation  operations as discontinued operations for the
     quarters and first six months ended June 30, 1997 and 1996. At December 31,
     1996, the assets have been  reclassified in the consolidated  balance sheet
     from their  historical  classifications  to separately  reflect them as net
     assets of  discontinued  operations.  Cash flows  related  to  discontinued
     operations have not been segregated in the  consolidated  statement of cash
     flows  for  1996.  Consequently,   amounts  on  the  consolidated  earnings
     statement may not agree with certain captions on the consolidated statement
     of cash flows for 1996.

(4)  Other Financial Information

     Sales and operating revenues are principally derived from the sale of crude
     oil, natural gas, natural gas liquids, geothermal steam, specialty minerals
     and nitrogen-based agricultural products produced by the company. Sales and
     operating revenues also include amounts received from the sale of purchased
     crude oil, natural gas and products.  Related purchase costs are classified
     as  expense  in  the  crude  oil  and  product  purchases  category  of the
     consolidated earnings statement.

     Capitalized  interest  totaled  $11  million  and $3 million for the second
     quarters of 1997 and 1996,  respectively.  For the first six months of 1997
     and  1996,   capitalized   interest   was  $16   million  and  $6  million,
     respectively.

(7)  Long Term Debt and Credit Agreements:

     Second quarter 1997 financing  activities primarily consisted of: increased
     borrowings  of $20 million on the $250 million  Thailand  revolving  credit
     facility,  bringing the balance to $150 million,  and debt  retirements  of
     $911 million in aggregate principal amount. The debt retirements  consisted
     of   approximately   $404  million  in  commercial   paper  repayments  and
     approximately  $507 million in debt securities  purchased in a tender offer
     on May  15,  1997.  The  debt  securities  consisted  of  $161  million  in
     debentures with an interest rate of 9-1/4 percent and $346 million in notes
     with interest rates of 8-3/4 percent and 9-3/4 percent. The debt securities
     were  purchased  for an  aggregate  price of  approximately  $555  million,
     including  a pre-tax  premium  of  approximately  $48  million  over  their
     aggregate  carrying value.  The premium,  together with related costs,  was
     recorded as an extraordinary item in the company's  consolidated  statement
     of earnings.  The company  anticipates  annual interest  expense savings of
     approximately  $34 million  (after-tax)  due to the debt buyback.  The debt
     repayments  and  debt  securities  purchases  substantially  completed  the
     company's program to reduce  outstanding debt by $800 million and were made
     with the  proceeds  from the sale of the  company's  West  Coast  refining,
     marketing and transportation assets.

(8)  Financial Instruments

     Risk Management and Derivative Instruments

     The primary  objectives of the company's  risk  management  policies are to
     reduce the overall  volatility of the company's  cash flows and to preserve
     revenues.  As part of its overall risk  strategy,  the company  enters into
     various derivative instrument contracts to hedge its exposure to changes in
     interest  rates,   changes  in  foreign   currency   exchange  rates,   and
     fluctuations in crude oil and natural gas prices.

     The  company  enters  into  interest  rate swap  agreements  to manage  the
     interest cost of its debt with the objective of minimizing  the  volatility
     and  magnitude of the  company's  borrowing  costs.  Net amounts  under the
     agreements  are  recorded  on a current  basis as  interest  expense in the
     consolidated earnings statement.  Related counterparty amounts are included
     in interest  payable in the consolidated  balance sheet.  Cash flow effects
     are  presented  in the "other"  category  under  working  capital and other
     changes in the operating  activities section of the consolidated cash flows
     statement.

     Various foreign currency forward and swap contracts are entered into by the
     company to manage its  exposures  to  adverse  impacts of foreign  currency
     fluctuations under debt and other  obligations.  Foreign currency gains and
     losses on the outstanding contracts are recognized in income and offset the
     foreign  currency  gains or losses of the underlying  obligations.  Related
     counterparty   amounts  are   included  in  accounts   receivable   in  the
     consolidated  balance sheet.  Changes in foreign  currency forward and swap
     contracts  are  included  with  associated   changes  in  foreign  currency
     obligations and offset in the statement of cash flows.

     Generally, commodity futures contracts with maturities of 18 months or less
     are entered into to hedge the company's  exposure to  fluctuations in crude
     oil and natural gas prices. While the intent of the company is to initially
     establish  hedged  positions for its forecasted  oil and gas  transactions,
     market  conditions may arise causing certain hedged  positions to be closed
     prior to their scheduled maturity dates. Accordingly,  all of the company's
     crude oil and natural gas risk management  derivative instrument activities
     are marked to market and gains and losses are recognized on a current basis
     in the underlying  commodity  revenues.  Related  counterparty  amounts are
     included in accounts  receivable in the  consolidated  balance sheet.  Cash
     flow effects for changes in the value of open  contracts  are  presented in
     accounts

                                   (Unaudited)

     receivable  under  working  capital  and  other  changes  in the  operating
     activities  section of the consolidated cash flows statement and offset the
     associated gains and losses reported in net earnings. Cash flows related to
     derivative  contracts  settled  during  the  period  are  reported  in  net
     earnings.

     The fair values of the company's financial instruments at June 30, 1997 are
     described below:

     The Deutsche  Mark currency  swap  agreement  had a notional  value of $110
     million  and a fair  value of  approximately  $33  million  based on dealer
     quotes.

     The company had outstanding  commodity futures contracts  covering the sale
     of 800 thousand  barrels of crude oil with a notional amount of $16 million
     and 32  billion  cubic feet of  natural  gas with a notional  amount of $71
     million.  The fair values of the contracts,  based on quoted market prices,
     were insignificant.

     The estimated fair value of the company's  long-term debt and capital lease
     obligations was $2,383 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  maturities.  The
     estimated fair value of the mandatorily  redeemable  convertible  preferred
     securities of the  company's  subsidiary  trust was $591 million,  based on
     dealer quotes.

(9)  Accrued Abandonment, Restoration And Environmental Liabilities:

     At June 30, 1997,  the company had accrued  $489 million for the  estimated
     future costs to abandon and remove  wells and  production  facilities.  The
     total   costs   for   abandonments   are   accrued   predominately   on   a
     units-of-production  basis  and  are  estimated  to be  approximately  $675
     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.

     At June 30,  1997,  the  company's  reserve for  environmental  remediation
     obligations  totaled  $234  million,  of which $73 million was  included in
     current  liabilities.  The reserve included estimated probable future costs
     of  $27  million  for  federal   Superfund  and  comparable   state-managed
     multiparty  disposal  sites;  $27 million for  formerly-operated  sites for
     which the  company  has  remediation  obligations;  $83  million  for sites
     related to businesses or  operations  that have been sold with  contractual
     remediation or indemnification  obligations;  $69 million for company-owned
     or controlled  sites where  facilities  have been closed or operations shut
     down; and $28 million for sites owned and/or  controlled by the company and
     utilized in its ongoing operations.

(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 may 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.

     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 cleanup 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 June 30,  1997,  the company had accrued  $234
     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  additional  remediation  costs
     aggregating approximately $200 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. 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 ongoing,  but it is possible that the most  substantial
     issues  raised in the Notice will  proceed to  litigation.  In an effort to
     resolve these issues without  litigation,  in October 1996, the company and
     the IRS  entered  into an  Agreement  to Mediate.  While the  parties  have
     selected a mediator, no date for the mediation has been set.

     The most significant issue raised in the Notice relates to an IRS challenge
     of a $341 million deduction taken by the company in its 1985 tax return for
     amounts paid under a settlement  agreement  with Mesa  Petroleum,  T. Boone
     Pickens and Drexel Burnham Lambert,  Incorporated, and certain others which
     ended a hostile  takeover  attempt by that group. The IRS contends that the
     deduction is not  allowable  because the payment was related  solely to the
     purchase of the  company's  common  stock.  Although the company  purchased
     shares under the settlement  agreement,  it properly reflected the purchase
     in its  records  at the fair  market  value of the  shares  purchased.  The
     deduction  at issue  relates to that  portion of the payment made under the
     settlement agreement that exceeded the value of the shares purchased.

     The second  largest issue raised in the Notice  relates to an IRS challenge
     of a  continued  deferral of  intercompany  gains which arose from sales of
     property  between  subsidiaries in 1982 and 1983. The IRS contends that the
     $201 million  balance of deferred  gain must be recognized in the company's
     taxable income for 1985 when the subsidiaries contributed the property to a
     wholly-owned master limited partnership.

     The total amount of tax and interest  that the company would be required to
     pay if the IRS were  ultimately to prevail on both of the issues  described
     in the two preceding  paragraphs,  after application of foreign tax credits
     and overpayments  related to other issues, and assuming a full disallowance
     of the claim for refund discussed below, is estimated at $414 million as of
     June 30, 1997.

     During the first quarter of 1997,  the IRS  examination  team completed its
     review of a claim for refund recently filed by the company  relating to its
     1985 tax  liability.  If the company  ultimately  prevails in its claim for
     refund,  the liability for the issues  described  above would be eliminated
     and the  company  would be  entitled  to a refund for  overpayment  of tax.
     Although the IRS has not  formally  disallowed  the claim,  the company has
     been  informed that the IRS  examination  team believes the claim should be
     disallowed.  In April 1997, the IRS examination  team sent the issue raised
     by the claim to the IRS National Office for technical  advice.  The company
     intends to vigorously defend the claim and dispute the proposed  deficiency
     and hopes to resolve  these matters  during 1997.  Should that effort fail,
     final  resolution  of these  matters is likely to be several  years away as
     they are not yet before a court.

     The company  believes it has adequately  provided in its accounts for items
     and issues not yet  resolved.  In the opinion of  management,  a successful
     outcome of these matters is reasonably likely. However, substantial adverse
     decisions  could  have  a  material  effect  on  the  company's   financial
     condition, operating results and liquidity in a given quarter and year

                                       8

     when such matters are resolved.

     Other Matters

     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.

(11) Sale of Accounts Receivable

     In  December  1995,  the  company  entered  into  an  agreement  to sell an
     undivided  interest  in a pool of its  trade  receivables.  As  collections
     reduced the amount of  receivables  included in the pool,  the company sold
     new  receivables  bringing the amounts sold up to the $200 million  maximum
     permitted by the agreement. This amount of sold receivables had remained at
     the $200  million  maximum  level.  Effective  January 1,  1997,  Financial
     Accounting   Standards  Board  (FASB)  Statement  of  Financial  Accounting
     Standards  (SFAS) No. 125,  "Accounting  for  Transfers  and  Servicing  of
     Financial  Assets and  Extinguishments  of  Liabilities",  disqualified the
     continued treatment of this transaction as a sale. Thus, at March 31, 1997,
     $200  million  was  reflected  in  the  financial  statements  as  accounts
     receivable with an offsetting  credit to accounts  payable.  In April 1997,
     the company repurchased this interest in the receivables.

Adjusted net earnings for the second  quarter of 1997  reflected  lower  average
sales prices for worldwide crude oil and domestic  natural gas compared with the
second quarter of 1996. In addition,  the second quarter and first six months of
1997 adjusted net earnings were impacted by lower domestic crude oil and natural
gas  production  and increased  international  exploration  expenses.  Partially
offsetting  these  negative  factors  were  increased  crude oil and natural gas
production in the Far East.

The Exploration and Production business segment was impacted primarily by price,
expense and production factors during the second quarter and first six months of
1997.

Second  quarter  1997  adjusted net earnings  were  adversely  impacted by lower
average sales prices for worldwide crude oil and domestic natural gas.  Compared
with the second  quarter of 1996,  average sales prices for worldwide  crude oil
decreased  by eight  percent to $17.28 per barrel and average  sales  prices for
worldwide natural gas decreased by four percent to $2.06 per thousand cubic feet
(mcf).  Although  average sales prices for  worldwide  crude oil and natural gas
were lower during the second quarter of 1997, they were higher for the first six
months of 1997 due to strong first quarter  prices.  During the first six months
of 1997, average sales prices for worldwide crude oil increased by seven percent
to $19.02  per  barrel and  average  sales  prices  for  worldwide  natural  gas
increased by four percent to $2.29 per mcf.

Second  quarter and first six months of 1997  adjusted  net  earnings  were also
affected by increased exploration  expenses,  primarily related to activities in
Thailand and Indonesia. Further reducing net earnings for the second quarter and
first six months of 1997 was an $11 million  dry hole charge for an  exploratory
well located offshore Brunei.

Increased Far East crude oil and natural gas production  partially  offset these
negative  factors  during the second  quarter and first six months of 1997.  Far
East  crude oil and  natural  gas  production  increased  by 13  percent  and 26
percent,  respectively,  compared with the second quarter of 1996. For the first
six months of 1997, Far East crude oil and natural gas  production  increased by
14 percent and 30 percent,  respectively,  compared  with the same period a year
ago.  Increased  natural  gas  production  for the second  quarter and first six
months of 1997 was  primarily  due to the start-up of a new  pipeline  system in
Thailand.  Although Far East crude oil and natural gas  production  were higher,
domestic and other foreign crude oil and natural gas production were down due to
natural  declines  and  maintenance  related  platform  shut-ins  in the Gulf of
Mexico.

During the second quarter and first six months of 1997,  special items consisted
of a $7 million  charge  related to a  gas-ignited  exploration  well blowout in
northeast  Bangladesh and a $17 million loss on the sale of the company's United
Kingdom operations.

Increased second quarter and first six months of 1997 adjusted net earnings were
the result of higher steam  generation at The Geysers and in the Philippines and
lower  depreciation  expense  due to the sale of domestic  geothermal  assets in
1996. Partially offsetting these positive factors were decreased revenues in the
Philippines  due to the  deferral  of 60 percent  of the  revenues  and  related
earnings  pending  the  settlement  of a  dispute  regarding  extension  of  the
company's service contract.

During the second quarter and first six months of 1997, the company recognized a
$7 million deferred tax benefit on exploration  expense incurred for the Sarulla
project.

</TABLE>

Compared  with the second  quarter  and first six months of 1996,  net  interest
expense  decreased  by 52 percent and 34 percent,  respectively,  as a result of
increased  capitalized  interest and paying down debt. Asset sales for the first
six months of 1997 primarily consisted of the sale of a company airplane. During
the  second  quarter  and  first  six  months of 1996,  assets  sales  primarily
consisted of miscellaneous real estate properties.

DISCONTINUED OPERATIONS

During the first six months of 1997, the company  recorded an additional loss on
disposal of its West Coast refining,  marketing and transportation operations of
$44 million (net of a $27 million tax benefit).  See note 3 to the  consolidated
financial statements for additional information.

Financial Condition and Capital Expenditures

For the first six months of 1997, cash flow from operating activities, including
working capital changes,  was $437 million,  compared with $693 million in 1996.
During the first six months of 1997, the  discontinued  refining,  marketing and
transportation operations had a negative cash flow of $20 million, compared with
a positive cash flow of $159 million for the same period in 1996.  The 1997 cash
flow from operations also reflected an $81 million escrow payment related to the
settlement  of the  "Catacarb"  litigation  and $27  million  for the  company's
buy-out  of  environmental   liabilities  related  to  the  UNO-VEN  partnership
restructuring.  Lower commodity prices,  higher  exploration  expense and higher
non-exploration and production international project expense also contributed to
reduced  operating cash flow.  Partially  offsetting these negative factors were
higher  production  and product  prices in Thailand and  Indonesia and lower net
interest expense.

Proceeds from asset sales were $1,834  million for the first six months of 1997.
The  amount  consisted  of:  $1,786  million  from the  sale of the  West  Coast
refining,   marketing  and   transportation   assets;  $25  million  for  Unocal
Hydrocarbon  Sales, $6 million from the sale of one of the company's  airplanes,
$8 million for miscellaneous real estate properties and $9 million from the sale
of miscellaneous assets including various oil and gas properties.

Capital  expenditures for the first six months of 1997 totaled $645 million,  an
increase of $23 million from the 1996 level of $622  million,  primarily  due to
increased  international  oil and gas activity.  Estimated  expenditures for the
full year 1997 are expected to reach $1.5 billion.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
 of Operations (continued)

Consolidated  working  capital at June 30, 1997 was $958 million,  a decrease of
$648  million from the year-end  1996 level of $1,606  million.  Included in the
1996 amount was $1,774 million in net assets of discontinued operations.

The company's total debt was $2,321 million at June 30, 1997, a decrease of $737
million  from the  year-end  1996  level of $3,058  million.  The  debt-to-total
capitalization  ratio  decreased to 45 percent from 52 percent at year-end 1996.
The  company  used a portion  of the  proceeds  from the sale of its West  Coast
refining,  marketing  and  transportation  assets to reduce long term debt.  See
notes 7 and 8 to the consolidated financial statements for related information.

Through June 30, 1997,  the company had  repurchased  approximately  2.4 million
shares of common stock for a total cost of  approximately  $92  million.  During
July 1997, the company  repurchased  approximately 2.1 million additional shares
of common stock for a cost of approximately $80 million.

ENVIRONMENTAL MATTERS

At  June  30,  1997,  the  company's  reserves  for  environmental   remediation
obligations  totaled $234 million,  of which $73 million was included in current
liabilities.  During the second  quarter,  cash  payments  of $13  million  were
applied  against the  reserve.  The company also  estimates  that it could incur
additional   remediation  costs  aggregating   approximately  $200  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:

RESERVE SUMMARY

      Total reserves ...........................................            $234
- --------------------------------------------------------------------------------

At year-end 1996, Unocal had received  notification from the U.S.  Environmental
Protection Agency that the company may be a potentially  responsible party (PRP)
at 39 sites and may share  certain  liabilities  at these  sites.  In  addition,
various state  agencies and private  parties had identified 37 other similar PRP
sites  that may  require  investigation  and  remediation.  During the first six
months of 1997, seven sites were added and four sites were resolved resulting in
a total of 79 sites. Of the total,  the company has denied  responsibility  at 6
sites and at another 8 sites the  company's  liability,  although  unquantified,
appears to be de  minimis.  The total  also  includes  24 sites  which are under
investigation or in litigation,  for which the company's  potential liability is
not  presently  determinable.  At  another  two  sites,  the  company  has  made
settlement payments and is in the final process of resolving its liabilities. Of
the remaining 39 sites,  where probable costs can be estimated,  reserves of $27
million have been established for future remediation and settlement costs. These
79 sites  exclude 61 sites where the company's  liability  has been settled,  or
where  the  company  has both no  evidence  of  liability  and there has been no
further  indication of liability by government  agencies or third parties for at
least a 12-month period.

Unocal does not  consider  the number of sites for which it has been named a PRP
as a relevant measure of liability. Although the liability of a PRP is generally
joint  and  several,  the  company  is  usually  just one of  several  companies
designated as a PRP. The company's  ultimate share of the  remediation  costs at
those sites often is not  determinable  due to many unknown factors as discussed
in Note 10. The solvency of other  responsible  parties and  disputes  regarding
responsibilities may also impact the company's ultimate costs.

The  company is subject to a number of  federal,  state and local  environmental
laws  and  regulations,  including  the  Comprehensive  Environmental  Response,
Compensation   and  Liability  Act  of  1980,  as  amended,   and  the  Resource
Conservation  and Recovery Act (RCRA).  Under these laws, the company is subject
to possible  obligations to remove or mitigate the environmental  effects of the
disposal or release of certain  chemical  and  petroleum  substances  at various
sites.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
of Operations (continued)

Corrective  investigations  and actions  pursuant to RCRA are being performed at
the company's Beaumont,  Texas, facility, its closed Colorado shale oil project,
and its  Washington,  Pennsylvania,  facility.  The  company  also must  provide
financial   assurance  for  future  closure  and   post-closure   costs  of  its
RCRA-permitted  facilities.  Because  these costs will be incurred at  different
times  and  over a  period  of many  years,  the  company  believes  that  these
obligations  are not likely to have a material  adverse  effect on the company's
results of operations or financial condition.

On May 14,  1997,  a draft  environmental  impact  report  (EIR)  prepared  by a
consultant to the County of San Luis Obispo,  California,  was issued for use by
the County, the Regional Water Quality Control Board -- Central Coast Region and
others in evaluating the company's  previously proposed remedial action plan, as
well as  alternative  courses  of action,  for  remediation  of the  underground
petroleum hydrocarbon  contamination at Avila Beach, California,  resulting from
former company  operations.  Certain of the alternatives  addressed in the draft
EIR would, if implemented,  entail remediation costs  significantly  higher than
the costs for the company's  plan. The company is currently  reviewing the draft
EIR and the  potential  financial  implications  to the  company of the  various
alternatives  addressed therein.  The county accepted public comments on the EIR
for a 60-day  period  through  July 14,  1997.  These  comments  will be used to
determine the final EIR which is not expected to be issued until late 1997.

See notes 9 and 10 for related information.

OTHER MATTERS

In the Philippines,  National Power  Corporation  (Napocor) agreed to extend the
period of negotiations  related to the service agreement dispute between Napocor
and the company's subsidiary,  Philippine Geothermal Inc., another six months to
year-end 1997.

FUTURE ACCOUNTING CHANGES

The Financial  Accounting Standards Board recently issued Statement of Financial
Accounting Standards (SFAS) No. 130, "Reporting  Comprehensive  Income" and SFAS
No. 131,  "Disclosures about Segments of an Enterprise and Related Information."
Both  statements  are effective for fiscal years  beginning  after  December 15,
1997.  The company is reviewing the  potential  financial  statement  impacts of
adopting these new accounting standards.

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
forward-looking statements.

In an effort to stabilize its economy,  Thailand implemented a new managed-float
currency  regime  allowing  its  currency  to  depreciate  in line  with  market
conditions.  The economic impact from allowing Thailand's currency to depreciate
is not expected to be material to the company due to price  control  adjustments
for  exchange  rate  differentials  provided in existing  sales  agreements.  In
addition,  the decrease in the exchange  rates  lowers the  company's  operating
costs that are denominated in Thailand's currency.

In June 1997, a gas exploration well in northern  Bangladesh blewout and ignited
resulting in a shut-down of operations at the site. A relief well is expected to
be drilled by mid August to seal off the gas.  The  company's  interest  in this
project is substantially  insured,  subject to deductibles for which the company
provided in its second quarter 1997  provision.  Additional  charges  related to
earnings are not expected to be material. The company holds a 50 percent working
interest in this well.

In Thailand,  the company  expects average gross natural gas production from the
nine fields it  operates  to be at or above one billion  cubic feet per day (650
million cubic feet net) for the remainder of the year. The expected  increase in
production  is due to  Petroleum  Authority of  Thailand's  pipeline and related
onshore pipelines and processing facilities becoming fully

operational.  Unocal has a 65 percent average net interest in the nine fields it
operates in the Gulf of Thailand.

In Indonesia,  at the Salak  geothermal field on the island of Java, the company
began supplying steam at one of four 55-megawatt  power plants,  Unit 3, in July
1997.  The  company  expects to begin  supplying  steam to the  remaining  three
55-megawatt power plants,  Units 4, 5 and 6, in September,  October and November
of 1997, respectively.

In Bangladesh,  the company is negotiating  for the  development of a gas field,
pipeline and power plants in the western region.

Although much of the  company's  investment  focus is targeted at  higher-return
growth opportunities in Asia, domestic exploration and production spending could
average $500 million annually if investment  opportunities become available. The
company is moving  aggressively  into  deepwater  exploration  and expanding its
onshore  and  outer  continental  shelf  activities  in the Gulf of  Mexico.  By
year-end 1997, the company plans to advance five to seven deepwater prospects to
drillable status and drill four to six wells by the end of 1998.

The company  anticipates  that urea and ammonia  sales  prices in  international
markets will remain below 1996 levels.  Consequently,  the Agricultural Products
group's  1997  earnings  are  expected to be  significantly  lower than the 1996
results.

                           PART II - OTHER INFORMATION

Item 1.   Legal Proceedings

There is incorporated by reference the information previously reported in Item 3
of Unocal's  Annual Report on Form 10-K (as amended) for the year ended December
31,  1996 (1996  Form 10-K (as  amended))  and in Item 1 of Part II of  Unocal's
Quarterly  Report on Form 10-Q for the  quarter  ended  March  31,  1997  (First
Quarter 1997 Form 10-Q),  the information  regarding  environmental  remediation
reserves in Note 9 to the consolidated financial statements in Item 1 of Part I,
the discussion  thereof in the  Environmental  Matters  section of  Management's
Discussion  and  Analysis  in Item 2 of Part I,  and the  information  regarding
contingent  liabilities in Note 10 to the consolidated  financial  statements in
Item 1 of Part I.

(1)  With reference to the "Catacarb" civil lawsuits, described in Paragraph (7)
     of Item 3 of the 1996 Form 10-K (as amended) and in Paragraph (1) of Item 1
     of Part II of the  First  Quarter  1997 Form  10-Q,  the  company  paid $81
     million into a settlement  escrow fund in May 1997, and the court certified
     the settlement in June 1997.

(2)  With  reference  to the  litigation  involving  the Yadana  gas  project in
     Myanmar,  described in  Paragraph  (13) of Item 3 of the 1996 Form 10-K (as
     amended)  and in  Paragraph  (5) of Item 1 of Part II of the First  Quarter
     1997 Form 10-Q,  several  developments  have  occurred  that may affect the
     course of the litigation:

     In John Doe I, et al. v. Unocal Corp., et al., U.S.  District Court for the
     --------------------------------------------
     Central District of California,  Civil No. 96-6959-RAP, the company filed a
     motion on June 2,  1997,  asking the Court to strike  from the  plaintiffs'
     complaint all allegations concerning claims of wrongful taking of property.
     This motion is scheduled to be heard on August 25, 1997.

     The  hearing  on  the  plaintiffs'  motion  for a  preliminary  injunction,
     previously  scheduled for June 9, 1997, has been continued.  The hearing on
     the  plaintiffs'  motion for class  certification  is set for September 22,
     1997.

     On June 3,  1997,  the  plaintiffs'  original  complaint  was  served  upon
     defendant Total in Paris, France. On July 23, 1997, Total filed a motion to
     dismiss for lack of personal  jurisdiction and  insufficiency of service of
     process.  Total's  motion to dismiss is  scheduled to be heard on September
     22, 1997.

     In National  Coalition  Government of the Union of Burma, et al. v. Unocal,
     --------------------------------------------------------------------------
     Inc., et al., U.S.  District Court for the Central  District of California,
     ------------
     Civil No.  96-6112-RAP,  the company's  motion to dismiss  remains  pending
     before the Court.

                     PART II - OTHER INFORMATION (continued)

     With  respect to both of the above  actions,  the Court had  solicited  the
     views of the United  States  Department  of State as to  whether  the Court
     should  continue to  entertain  the actions in light of the foreign  policy
     issues  involved.  On July 9, 1997,  the United States filed a Statement of
     Interest  with the Court,  together  with a letter  from the United  States
     Department of State setting forth the Department's  response to the Court's
     request.  In the letter,  the Department stated,  among other things,  that
     because  the  current  record  in  the  two  cases  "is  undeveloped,"  the
     Department  "is not in a  position  at this  time to  express  a view as to
     whether the act of state  doctrine is  necessarily  implicated in the cases
     before  the  Court,  nor  would we want this  letter to imply  that we have
     reviewed or taken a position on any other legal issues in the  litigation."
     The  Department  also  stated  that  "[n]evertheless,  in response to Judge
     Paez's request,  the Department can state that at this time adjudication of
     the claims based on  allegations of torture and slavery would not prejudice
     or impede the conduct of U.S. foreign relations with the current government
     of Burma."

(3)  On June 12, 1997, the State of Arizona filed a lawsuit  against the company
     (State of Arizona v. Union Oil  Company of  California,  Superior  Court of
     ------------------------------------------------------
     Maricopa  County,  No.  CV97-10829)  alleging  that it has  not  diligently
     pursued the  investigation of the extent of contamination  resulting from a
     release of petroleum from  underground  storage tanks at a service  station
     formerly operated by the company in Tempe,  Arizona.  The state seeks civil
     penalties  of up to  $10,000  per day.  The  company  is in the  process of
     investigating this matter, and it is possible that penalties aggregating in
     excess of $100,000 could be imposed.

(4)  On July 2, 1997,  the company  received a Notice of Violation from the U.S.
     Environmental   Protection  Agency,  Region  X  (EPA),   regarding  alleged
     violations of the Prevention of Significant Deterioration Standards and the
     New Source Performance  Standards of the Federal Clean Air Act, as amended,
     at the company's  Kenai,  Alaska,  fertilizer  plant.  The company has been
     engaged in negotiations with the EPA to settle these  allegations  pursuant
     to a consent  decree  which is  expected  to involve  the  payment of civil
     penalties in excess of $500,000.

Item 2.  Changes in Securities

During the second quarter of 1997, the company  awarded 5,377  restricted  stock
units to certain  nonemployee  directors  pursuant to the terms of the company's
Directors'  Restricted  Stock  Plan.  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 were  awarded (1) as annual  grants  equal to 20 percent of
each of the nonemployee  director's fees earned during the prior 12 months,  (2)
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 (3)  upon the  credit  of
dividend  equivalents upon units previously issued. The units are paid out in an
equal number of shares of Unocal common stock at the end of a restriction period
elected by each director, or upon his or her earlier termination of service as a
director.

During the second  quarter of 1997,  2,134  restricted  stock  units held by one
nonemployee director, Mr. MacDonald G. Becket, were paid out in shares of Unocal
common stock upon his retirement from the Board.  The shares were not registered
under the Act in reliance upon the exemption contained in Section 3(a)(9) of the
Act for  securities  exchanged by the issuer with its existing  security-holders
exclusively where no commission or other  remuneration is paid or given directly
or indirectly for soliciting such exchange.

During the second  quarter of 1997,  Unocal issued 47 shares of its common stock
upon the  conversion  of 41 of the 6-1/4  percent  trust  convertible  preferred
securities of Unocal Capital Trust.  The common shares were not registered under
the Act in reliance upon the exemption  contained in Section  3(a)(9) of the Act
for  securities  exchanged  by the  issuer  with its  existing  security-holders
exclusively where no commission or other  remuneration is paid or given directly
or indirectly for soliciting such exchange.

Item 4.   Submission of a Vote of Security Holders

The Annual Meeting of  Stockholders  of Unocal  Corporation  was held on June 2,
1997.  The  following  actions  were  taken by the  stockholders  at the  Annual
Meeting,  for which proxies were  solicited  pursuant to Regulation 14 under the
Securities Exchange Act of 1934, as amended:
