Below are certain definitions of key terms that may be in use in this Form 10-Q
report.

M       Thousand                              Bbl    Barrels
MM      Million                               Cf/d   Cubic feet per day

CF      Cubic feet                            Btu    British thermal units
BOE     Barrels of oil equivalent             DD&A   Depreciation, depletion
                                                     and amortization
Liquids Crude oil, condensate and NGLs        NGLs   Natural gas liquids
Bbl/d   Barrels per day


o    API Gravity is a measurement of the gravity (density) of crude oil and
     other liquid hydrocarbons by a system recommended by the American Petroleum
     Institute ("API"). The measuring scale is calibrated in terms of "API
     degrees." The higher the API gravity, the lighter the oil.
o    Bilateral institution refers to a country specific institution, which lends
     funds primarily to promote the export of goods from that country. Examples
     of bilateral institutions are Ex-Im (U.S.), Hermes (Germany), SACE (Italy),
     COFACE (France), and JBIC (Japan).
o    BOE A term used to quantify oil and natural gas amounts using the same
     measurement. Gas volumes are converted to barrels of oil on the basis of
     energy content, where the volume of natural gas that when burned produces
     the same amount of heat as a barrel of oil (6,000 cubic feet of gas equals
     one barrel of oil).
o    British Thermal Units ("Btu") is a measure of the amount of heat required
     to raise the temperature of one pound of water one degree Fahrenheit.
o    Delineation  or appraisal  well is a well drilled in an unproven area
     adjacent to a discovery well to define the boundaries of the reservoir.
o    Development well is a well drilled within the proved area of an oil or
     natural gas reservoir to a depth of a stratigraphic horizon known to be
     productive.
o    Dry hole is a well believed to be incapable of producing hydrocarbons in
     sufficient commercial quantities to justify future capital expenditures for
     completion and additional infrastructure.
o    Economic interest method pursuant to production sharing contracts is a
     method by which the Company's share of the cost recovery revenue and the
     profit revenue is divided by year-end oil and gas prices and represents the
     volume that the Company is entitled to. The lower the commodity price, the
     higher the volume entitlement, and vice versa.
o    Exploratory well is a well drilled to find and produce oil or natural gas
     reserves that is not a development well.
o    Farm-in or farm-out is an agreement whereby the owner of a working interest
     in an oil and gas lease assigns the working interest or a portion thereof
     to another party who desires to drill on the leased acreage. The assignor
     usually retains a royalty or reversionary interest in the lease. The
     interest received by an assignee is a "farm-in," while the interest
     transferred by the assignor is a "farm-out."
o    Field is an area consisting of a single reservoir or multiple reservoirs
     all grouped on or related to the same individual geological structural
     feature or stratigraphic condition.
o    Floating Production Storage and Offloading ("FPSO") technology refers to
     the use of a vessel that is stationed above or near an offshore oil field.
     Produced fluids from subsea completion wells are brought by flowlines to
     the vessel where they are separated, treated, stored and then offloaded to
     another vessel for transportation.
o    Gross acres or gross wells are the total acres or wells in which a working
     interest is owned.
o    Hydrocarbons are organic compounds of hydrogen and carbon atoms that form
     the basis of all petroleum products.

                                       i


o    Lifting is the amount of liquids each working-interest partner takes
     physically. The liftings may actually be more or less than actual
     entitlements that are based on royalties, working interest percentages, and
     a number of other factors.
o    Liquefied Natural Gas ("LNG") is a gas, mainly methane, which has been
     liquefied in a refrigeration and pressure process to facilitate storage and
     transportation.
o    Liquefied Petroleum Gas ("LPG") is a mixture of butane, propane and other
     light hydrocarbons. At normal temperature it is a gas, but it can be cooled
     or subjected to pressure to facilitate storage and transportation.
o    Multilateral institution refers to an institution with shareholders from
     multiple countries that lends money for specific development reasons.
     Examples of multilateral institutions are International Finance Corporation
     ("IFC"), European Bank for Reconstruction and Development ("EBRD"), and
     Asian Development Bank ("ADB").
o    Natural Gas Liquids ("NGLs") are primarily ethane, propane, butane and
     natural gasolines which can be extracted from wet natural gas and become
     liquid under various combinations of increasing pressure and lower
     temperature.
o    Net acreage and net oil and gas wells are obtained by multiplying gross
     acreage and gross oil and gas wells by the Company's working interest
     percentage in the properties.
o    Net pay is the amount of oil or gas saturated rock capable of producing oil
     or gas.
o    Production Sharing Contract ("PSC") is a contractual agreement between the
     Company and a host government whereby the Company, acting as contractor,
     bears all exploration costs, development and production costs in return for
     an agreed upon share of production.
o    Producible well is a well that is found to be capable of producing
     hydrocarbons in sufficient quantities such that proceeds from the sale of
     such production exceed production expenses and taxes.
o    Prospective acreage is lease acreage on which wells have not been drilled
     or completed to a point that would permit the production of commercial
     quantities of oil and natural gas.
o    Proved acreage is acreage that is allocated to producing wells or wells
     capable of production or to acreage that is being developed.
o    Reservoir is a porous and permeable underground formation containing oil
     and/or natural gas enclosed or surrounded by layers of less permeable rock
     and is individual and separate from other reservoirs.
o    Subsea tieback is a well with the wellhead equipment located on the bottom
     of the ocean.
o    Take-or-Pay is a type of contract clause where specific quantities of a
     product must be paid for, even if delivery is not taken. Normally, the
     purchaser has the right in following years to take product that had been
     paid for but not taken.
o    Trend or Play is an area or region of concentrated activity with a group of
     related fields and prospects.
o    Working interest is the percentage of ownership that the Company has in a
     joint venture, partnership or consortium.

Results for the six months ended June 30, 2002, are not necessarily indicative
of future financial results.

Certain items in the prior year financial statements have been reclassified to
conform to the 2002 presentation.

2.       Accounting Changes

Effective January 1, 2002, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 142, "Goodwill and Other Intangible Assets". SFAS No. 142
addresses accounting for goodwill and identifiable intangible assets subsequent
to their initial recognition, eliminates the amortization of goodwill and
provides specific steps for testing the impairment of goodwill. Separable
intangible assets that are not deemed to have an indefinite life will continue
to be amortized over their useful lives. SFAS No. 142 also eliminates
amortization of the excess of cost over the underlying equity in the net assets
of an equity method investee that is recognized as goodwill. The adoption of the
statement did not have a material effect on the Company's financial position and
results of operations.

Effective January 1, 2002, the Company also adopted SFAS No. 144, "Accounting
for the Impairment or Disposal of Long-Lived Assets", which addresses financial
accounting and reporting for the impairment or disposal of long-lived assets.
SFAS No. 144 supersedes SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of", and the
accounting and reporting provisions of Accounting Principles Board Opinion No.
30, "Reporting the Results of Operations--Reporting the Effects of Disposal of a
Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring
Events and Transactions". The adoption of SFAS No. 144 did not have a material
effect on the Company's financial position and results of operations.

The Company has adopted SFAS No. 145,  "Rescission  of SFAS No. 4, 44, and 64,
Amendment of SFAS No. 13, and  Technical  Corrections."  This Statement rescinds
SFAS No. 4,  "Reporting  Gains and Losses from  Extinguishment  of Debt",  and
an amendment of that Statement, SFAS No. 64,  "Extinguishments  of Debt Made to
Satisfy  Sinking-Fund  Requirements".  This  Statement  also  rescinds or amends
other existing authoritative  pronouncements to make various technical
corrections,  clarify meanings, or describe their applicability under changed
conditions.  The adoption of SFAS No. 145 did not have a material effect on the
Company's  financial  position and results of operations.

                                      -4-



In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs Associated
with Exit or Disposal Activities". This statement provides guidance on the
recognition and measurement of liabilities associated with disposal activities
and is effective for the Company on January 1, 2003.

3.       Other Financial Information

During the second quarters of 2002 and 2001, approximately 23 percent and 25
percent, respectively, of total sales and operating revenues were attributable
to the resale of liquids and natural gas purchased from others in connection
with marketing activities. For the six months ended June 30, 2002 and 2001,
these percentages were approximately 22 percent and 32 percent, respectively.
Related purchase costs are classified as expense in the crude oil, natural gas
and product purchase category on the consolidated earnings statement. The
current year percentage decreases were principally due to lower purchases of
domestic crude oil from third parties for resale. During 2001, management
decided to decrease its outside crude oil purchases for resale due to increased
volatility in the oil markets.

Capitalized interest totaled $10 million and $6 million for the second quarters
of 2002 and 2001, respectively, and $19 million and $11 million for the six
months ended 2002 and 2001, respectively. The increase was primarily due to the
capitalized interest related to the Mad Dog development project in the Gulf of
Mexico and the West Seno oil and gas development project in the deepwater Kutei
Basin, offshore East Kalimantan, Indonesia.

Exploration expense on the consolidated earnings statement consisted of the
following:


                                                                   For the Three Months         For the Six Months

4.       Restructuring

In June 2002, the Company adopted a restructuring plan that resulted in the
accrual of a $19 million pre-tax restructuring charge. The charge included the
estimated costs of terminating approximately 200 employees in the Company's
Sugar Land, Texas, office and field locations. The restructuring plan involves
organizational changes to eliminate unnecessary work processes in the Company's
Gulf Region business unit, which is part of the U.S. Lower 48 operations in the
Exploration and Production segment.

The restructuring charge was reflected in the operating expense line on the
consolidated earnings statement and included approximately $14 million for
termination costs to be paid to the employees over time, about $3 million for
outplacement and other costs and about $2 million for benefit plan curtailment
costs. All of the affected employees had been terminated or had received
termination notices as of June 30, 2002.

5.       Impairments

The Company, as part of its regular assessment, reviewed its developed and
undeveloped oil and gas properties and other long-lived assets for possible
impairment. In the second quarter of 2002, the Company recorded a pre-tax charge
of $21 million, or $13 million after-tax, for the impairment of oil and gas
fields in Alaska and the Gulf of Mexico region. The impairment in Alaska, which
made up the majority of the amount recorded, was $18 million pre-tax, or $12
million after-tax.

                                      -5-


6.       Income Taxes

Income taxes on earnings from continuing operations for the second quarter and
six months periods of 2002 were $95 million and $135 million, respectively,
compared with $180 million and $370 million for the comparable periods of 2001.
The effective income tax rates for the second quarter and six months periods of
2002 were 46 percent and 50 percent, respectively, compared with 43 percent and
41 percent for the comparable periods of 2001.

The higher effective income tax rates for the second quarter and the first six
months of 2002, as compared with the same periods a year ago, reflect currency
effects primarily in Thailand along with the effect of changes in the mix of
domestic earnings in the prior year periods and losses in the current year
periods coupled with foreign earnings for all periods reported, which are
generally taxed at higher rates.

7.       Earnings Per Share

The following are reconciliations of the numerators and denominators of the
basic and diluted earnings per share ("EPS") computations for earnings from
continuing operations for the second quarters and six months ended June 30, 2002
and 2001:

Not included in the computation of diluted EPS for the three months ended June
30, 2002 and 2001, were options outstanding to purchase approximately 1.9
million and 3.4 million shares, respectively, of common stock. These options
were not included in the computation as the exercise prices were greater than
average market prices of the common shares during the respective quarters.

10.      Long Term Debt and Credit Agreements

During the first six months of 2002, the Company's consolidated debt, including
the current portion, increased by $213 million. This net increase included $440
million in new commercial paper borrowings, the proceeds of which were used to
refinance maturing debt and for general corporate purposes. The commercial paper
had a weighted average interest rate of 2.23 percent at June 30, 2002. The
Company retired $132 million of maturing medium-term notes during the first six
months of 2002. In February 2002, the Company's Northrock Resources Ltd.
subsidiary redeemed its $35 million "Series A" and $40 million "Series B" senior
U.S. dollar-denominated notes, which bore interest of 6.54 percent and 6.74
percent, respectively. The Company's Pure Resources, Inc. ("Pure") subsidiary
reduced its long-term debt, included in the Company's consolidated debt, by $16
million principally due to a decrease in borrowing under its revolving credit
facilities. Pure's debt was $571 million at June 30, 2002. Neither Unocal nor
Union Oil guarantees any of Pure's debt.

11.      Accrued Abandonment, Restoration and Environmental Liabilities

At June 30, 2002, the Company had accrued $472 million for the estimated future
costs to abandon and remove wells and production facilities. The total costs for
these abandonments are predominantly accrued on a unit-of-production basis and
are estimated to be approximately $700 million. This estimate was derived in
large part from abandonment cost studies performed by independent third party
firms and is used to calculate the amount to be amortized. The Company's reserve
for environmental remediation obligations at June 30, 2002 totaled $231 million,
of which $116 million was included in current liabilities.

                                      -8-


12.      Commitments and Contingencies

The Company has 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, local
and foreign 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, even
if liability is determined to be probable, to quantify the liability or estimate
a range of possible exposure. In such cases, the amounts of the Company's
liabilities are indeterminate due to the potentially large number of claimants
for any given site or exposure, the unknown magnitude of possible contamination,
the imprecise and conflicting engineering evaluations and estimates of proper
clean-up methods and costs, the unknown timing and extent of the corrective
actions that may be required, the uncertainty attendant to the possible award of
punitive damages, the recent judicial recognition of new causes of action, the
present state of the law, which often imposes joint and several and retroactive
liabilities on PRPs, the fact that the Company is usually just one of a number
of companies identified as a PRP, or other reasons.

As disclosed in note 11, at June 30, 2002, the Company had accrued $231 million
for estimated future environmental assessment and remediation costs at various
sites where liabilities for such costs are probable and reasonably estimable.
The Company may also incur additional liabilities in the future at sites where
remediation liabilities are probable but future environmental costs are not
presently reasonably estimable because the sites have not been assessed or the
assessments have not advanced to the stage where costs are reasonably estimable.
At those sites where investigations or feasibility studies have advanced to the
stage of analyzing feasible alternative remedies and/or ranges of costs, the
Company estimates that it could incur possible additional remediation costs
aggregating approximately $255 million. The amount of such possible additional
costs reflects the aggregate of the high ends of the ranges of costs of feasible
alternatives identified by the Company for those sites with respect to which
investigation or feasibility studies have advanced to the stage of analyzing
such alternatives. However, such estimated possible additional costs are not an
estimate of the total remediation costs beyond the amounts reserved, because
there are sites where the Company is not yet in a position to estimate all, or
in some cases any, possible additional costs. Both the amounts reserved and
estimates of possible additional costs may change in the near term, and in some
cases could change substantially, as additional information becomes available
regarding the nature and extent of site contamination, required or agreed-upon
remediation methods and other actions by government agencies and private
parties.

                                      -9-



The accrued costs and the possible additional costs are shown below in four
categories of sites:


                                                                          At June 30, 2002

      Total reserves                                                        $ 231          $ 255
=================================================================================================

The time frame over which the amounts included in the reserve may be paid extend
from the near term to several years into the future. The sites included in the
above categories are in various stages of investigation and remediation;
therefore, the related payments against the existing reserve will be made in
different future periods. Also, some of the work is dependent upon reaching
agreements with regulatory agencies and/or other third parties on the scope of
remediation work to be performed, who will perform the work, the timing of the
work, who will pay for the work and other factors that may have an impact on the
timing of the payments for amounts included in the reserve. For some sites, the
remediation work will be performed by other parties, such as the current owners
of the sites, and the Company has a contractual agreement to pay a share of the
remediation costs. For these sites, the Company generally has less control over
the timing of the work and consequently the timing of the associated payments.
Based on available information, the Company estimates that the majority of the
amounts included in the reserve will be paid within the next three to five
years.

At the sites where the Company has a contractual agreement to share remediation
costs with third parties, the reserve reflects the Company's estimated share of
those costs. In many of the oil and gas sites, remediation cost sharing is
included in joint venture agreements that were made with third parties during
the original operation of the site. In many cases where the Company sold
facilities or a business to a third party, sharing of remediation costs for
those sites may be included in the sales agreement.

Contamination in the sites of the "Superfund and Similar Sites" category was the
result of the disposal of substances at these sites by one or more PRPs.
Contamination of these sites could be from many sources, of which the Company
may be one. The Company has been notified that it is a PRP at the sites included
in this category. At the sites where the Company has not denied liability, the
Company's contribution to the contamination at these sites was primarily from
waste from the current and former operations identified above.

The "Active Company Facilities" category includes oil and gas fields and mining
operations. The sites are primarily contaminated with crude oil, oil field waste
and other petroleum hydrocarbons. Contamination at the active mining sites was
principally the result of the impact of mined material on the groundwater and/or
surface water at these sites.

The "Company Facilities Sold and Former Company-Operated Sites" and "Inactive or
Closed Company Facilities" categories include former Company refineries,
transportation and distribution facilities and service stations. The required
remediation of these sites is mainly for petroleum hydrocarbon contamination as
the result of leaking tanks or impoundments that were used in these operations.
Also, included in these categories are former oil and gas fields that the
company no longer operates. In most cases, these sites are contaminated with
crude oil, oil field waste and other petroleum hydrocarbons. Contamination at
other sites in this category was the result of former industrial chemical and
polymers manufacturing and distribution facilities, agricultural chemical retail
businesses and ferromolybdenum production operations.

                                      -10-



Superfund and similar sites - At June 30, 2002, Unocal had received notification
from the U.S. Environmental Protection Agency ("EPA") that the Company may be a
PRP at 30 sites and may share certain liabilities at these sites. Of the total,
five sites are under investigation and/or litigation and the Company's potential
liability is not presently determinable and for two sites the Company has denied
responsibility. At one site, the Company's potential liability appears to be de
minimis. Of the remaining 22 sites, where probable and to the extent costs can
be reasonably estimated, reserves of $12 million have been established for
future remediation and settlement costs.

Various state agencies and private parties had identified 23 other similar PRP
sites. Two sites are under investigation and/or litigation and the Company's
potential liability is not presently determinable. At three sites the Company's
potential liability appears to be de minimis. At another site, the Company has
made final settlement payments and is in the process of completing its
involvement in the site. The Company has denied responsibility at two sites.
Where probable and to the extent costs can be reasonably estimated at the
remaining 15 sites, reserves of $6 million have been established for future
remediation and settlement costs.

In addition to the total of $18 million in reserves mentioned above, the Company
has also estimated that additional costs of $11 million are possible for the
"Superfund and Similar Sites" category.

Included in this category of sites are:

o        The McColl site in Fullerton, California
o        The Operating Industries site in Monterey Park, California
o        The Casmalia Waste site in Casmalia, California

These 53 sites exclude 108 sites where the Company's liability has been settled,
or where the Company has 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.

The Company 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 numerous
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. The
solvency of other responsible parties and disputes regarding responsibilities
may also impact the Company's ultimate costs.

Active Company facilities - The Company has a reserve of $37 million for
estimated future costs of remedial orders, corrective actions and other
investigation, remediation and monitoring obligations at certain operating
facilities and producing oil and gas fields. Included in this category are:

o        The Molycorp molybdenum mine in Questa, New Mexico
o        The Molycorp lanthanide facility in Mountain Pass, California
o        Alaska oil and gas properties

The company estimates that it may incur possible additional costs of $67 million
for this group of sites.

Company facilities sold with retained liabilities and former Company-operated
sites - Company facilities sold with retained liabilities include:

o West Coast refining, marketing and transportation sites
o Auto/truckstop facilities throughout the U.S.
o Industrial chemical and polymer sites in the South, Midwest and California
o Agricultural chemical sites in the West and Midwest

In each sale, the Company retained a contractual remediation or indemnification
obligation and is responsible only for certain environmental problems associated
with its past operations. The reserves represent estimated future costs for
remediation work: identified prior to the sale of these sites; included in
negotiated agreements with the buyers of these sites where the Company retained
certain levels of remediation liabilities; and/or identified in subsequent
claims made by buyers of the properties. Former Company-

                                     -11-


operated sites include service stations, distribution facilities and oil and gas
fields that were previously operated but not owned by the Company. The Company
has an aggregate reserve of $97 million and additional costs of $72 million are
possible for this category. The possible additional costs are primarily related
to service station and distribution facilities and oil and gas properties.

Inactive or closed Company facilities - Reserves of $79 million have been
established for these types of facilities. The major sites in this category are:
o The Guadalupe oil field on the central California coast
o The Molycorp Washington and York facilities in Pennsylvania
o The Beaumont Refinery in Texas

These sites also have possible additional costs of $95 million associated with
them.

The Company is subject to federal, state and local environmental laws and
regulations, including the Comprehensive Environmental Response, Compensation
and Liability Act of 1980 ("CERCLA"), as amended, the Resource Conservation and
Recovery Act ("RCRA") and laws governing low level radioactive materials. 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,
petroleum and radioactive substances at various sites. Corrective investigations
and actions pursuant to RCRA and other federal, state and local environmental
laws are being performed at the Company's Beaumont, Texas, facility, a former
agricultural chemical facility in Corcoran, California, and Molycorp's
Washington, Pennsylvania, facility. In addition, Molycorp is required to
decommission its Washington and York facilities in Pennsylvania pursuant to the
terms of their respective radioactive source materials licenses and
decommissioning plans.

The Company also must provide financial assurance for future closure and
post-closure costs of its RCRA-permitted facilities and for decommissioning
costs at facilities that are under radioactive source materials licenses.
Pursuant to a 1998 settlement agreement between the Company and the State of
California and the subsequent stipulated judgment entered by the Superior Court,
the Company must provide financial assurance for anticipated costs of
remediation activities at its inactive Guadalupe oil field. Also, pursuant to a
1995 settlement agreement between Molycorp and the California Department of
Toxic Substances Control (and subsequent final judgment entered by the Superior
Court), the Company must provide financial assurance for anticipated costs of
disposing of certain wastes, as well as closing facilities associated with the
handling of those wastes, at Molycorp's Mountain Pass, California, facility.
Although these costs are likely to be incurred at different times and over a
period of many years, the Company believes that these obligations could have a
material adverse effect on the Company's results of operations but are not
expected to be material to the Company's consolidated financial condition or
liquidity.

The total environmental remediation reserves recorded on the consolidated
balance sheet represent the Company's estimates of assessment and remediation
costs based on currently available facts, existing technology and presently
enacted laws and regulations. The remediation cost estimates, in many cases, are
based on plans recommended to the regulatory agencies for approval and are
subject to future revisions. The ultimate costs to be incurred could exceed the
total amounts reserved. The reserve will be adjusted as additional information
becomes available regarding the nature and extent of site contamination,
required or agreed-upon remediation methods and other actions by government
agencies and private parties. Therefore, amounts reserved may change
substantially in the near term.

The Company maintains insurance coverage intended to reimburse the cost of
damages and remediation related to environmental contamination resulting from
sudden and accidental incidents under current operations. The purchased
coverages contain specified and varying levels of deductibles and payment
limits. Although certain of the Company's contingent legal exposures enumerated
above are uninsurable due either to insurance policy limitations, public policy
or market conditions, management believes that its current insurance program
significantly reduces the possibility of an incident causing a material adverse
financial impact to the Company.

Certain Litigation and Claims

City of Santa Monica MTBE Lawsuit: In June 2000, the City of Santa Monica (the
"City") sued Shell Oil Company and other oil companies, including the Company,
for contamination with methyl tertiary butyl ether ("MTBE") and a related
chemical of water pumped from its Charnock wellfield (City of Santa Monica v
Shell Oil Company et al, California Superior Court, Orange County, Case No.
01CC04331). In August 2001, Shell filed a cross-complaint against the Company
and other oil companies, seeking the recovery of the funds it has expended to
respond to the contamination. Further proceedings on this cross-complaint remain
stayed.

The City's first amended complaint, filed in May 2002, alleges causes of action
for strict liability (gasoline containing MTBE as a defective product designed,
manufactured and sold without adequate warnings), negligence, trespass, public
and private nuisance, declaratory relief and unfair competition. The City seeks
damages, a declaration that the defendants are liable for all remedial actions,
abatement of nuisance and injunctive relief. The City alleges that releases from
sites of units of Shell, ChevronTexaco Corporation and ExxonMobil Corporation
were the releases which caused the wellfield to be shut down. Releases from
Company sites allegedly impacted the wellfield subsequently.

In July 2002, the City, ChevronTexaco and ExxonMobil announced a proposed
settlement, under which the two companies would pay the City $30 million and
construct and operate a water treatment plant. Future settlement and/or judgment
amounts paid to the City from other defendants would go in part into an
operating account, from which the two companies could be reimbursed for part or
all of their treatment plant costs, as well as certain other costs. The Company,
Tosco Corporation (now a unit of Phillips Petroleum Company) and other
defendants, but not the Shell defendants, have been invited to participate in
this settlement. The Company is evaluating its position with regard to
participation, which would involve its paying the City $7.5 million and
contributing to the costs of the treatment plant. However, based on a rigorous
technical analysis of the data, the Company believes it has strong defenses to
the allegations in the complaint, including the lack of evidence that its former
service stations or activities are responsible for any contamination that has
reached or threatens the wellfield. The Company also believes it has certain
available defenses that the settling defendants and others may not have due to
tolling agreements they entered into with the City; and, unlike the Shell
defendants and the settling defendants, the Company is neither the object of
punitive damages claims nor a cause of the wellfield's being originally shut
down. The Company is also subject to potential partial responsibility for
liabilities arising from its former gasoline marketing business that was sold to
Tosco in 1997. The Company's current analysis does not indicate any such
liabilities are likely to be significant.

For several years prior to the City's suit, the EPA and the California Regional
Water Quality Control Board have asserted jurisdiction over contamination of
groundwater potentially affecting the wellfield, and these agencies have issued
a number of orders under RCRA and state law to the Shell defendants and the
other defendant oil companies, including the Company, with respect to both
investigation of individual facilities and regional contamination, and requiring
replacement of water lost to the City, which Shell is currently providing. The
impact of the proposed settlement in the City's lawsuit on future government
agency actions is uncertain. The Company has submitted to these agencies several
technical analyses, which it believes demonstrate that its sites are not a part
of any regional contamination problem, but, rather, present, at the most,
localized issues which the Company, under agency oversight, has been
successfully resolving.

Agrium  Litigation:  In June 2002,  a lawsuit  was filed  against the Company by
Agrium Inc., a Canadian  corporation,  and a U. S.  subsidiary in the California
Superior  Court,  Los Angeles  County (Agrium U.S. Inc. and Agrium Inc. v. Union
Oil Company of California,  Case No. BC275407). The Company subsequently removed
the case to the U.S. District Court for the Central District of California (Case
No. 02-04769 Nm).

The Agrium entities ("Agrium") allege numerous causes of action relating to
their purchase from the Company of a nitrogen-based fertilizer plant on the
Kenai Peninsula, Alaska, in September 2000. The primary allegations involve the
Company's obligation to supply natural gas to the plant pursuant to a Gas
Purchase and Sale Agreement (the "GPSA") between the parties. Agrium alleges
that the Company misrepresented the amount of gas reserves available for sale to
the plant as of the closing of the transaction and that the Company has failed
to develop additional reserves for sale to the plant. Agrium also alleges that

                                      -13-



the Company misrepresented the condition of the general effluent sewer at the
plant and made misrepresentations regarding other environmental matters.

Agrium seeks damages in an unspecified amount for breach of such representations
and warranties, as well as for alleged misconduct by the Company in operating
and managing certain oil and gas leases and other facilities. Agrium also seeks
declaratory relief concerning the base price of gas under the GPSA, as well as
for the calculation of payments under a "Retained Earnout" covenant that
entitles the Company to certain contingent payments based on the price of
ammonia subsequent to the September 2000 closing. The complaint includes demands
for punitive damages and attorneys' fees.

Also in June  2002,  the  Company  filed a  lawsuit  against  Agrium in the U.S.
District  Court for the  Central  District of  California  (Union Oil Company of
California v. Agrium Inc. and Agrium U.S. Inc., Case No. 02-04518 Nm(Ctx)).  The
Company seeks declaratory  relief in its favor against the allegations of Agrium
set forth above and for judgment on the Retained  Earnout in the amount of $16.6
million, together with interest accrued subsequent to May 31, 2002.

The Company believes that certain portions of its disputes with Agrium are
subject to binding arbitration under the terms of the GPSA, and has initiated
arbitration respecting the gas supply available under that agreement. Agrium
claims the dispute resolution provisions of the agreement for the sale of the
plant (the "PSA") supersede the arbitration provisions of the GPSA. Agrium has
filed motions to stay the Company's lawsuit, to enjoin implementation of the
arbitration and for Agrium's lawsuit to be remanded to the state court. A
hearing on these motions is set for September 2002. The federal court recently
denied a motion by Agrium to temporarily restrain implementation of the
arbitration.

The GPSA contains a contractual limit on liquidated damages of $25 million per
year, not to exceed a total of $50 million over the life of the agreement. In
addition, the PSA contains a limit on damages of $50 million. The Company
believes it has a meritorious defense to each of the Agrium claims, but that in
any event its exposure to damages for all disputes is limited by the agreements.
Agrium alleges that it is entitled to recover damages in excess of those
amounts.

Petrobangla Claim: In July 2002, the Company's subsidiary Unocal Bangladesh
Blocks Thirteen and Fourteen, Ltd. (which was acquired in 1999 from Occidental
Petroleum Corporation and, prior to the recent completion of Bangladesh
name-change formalities, was still known in Bangladesh as Occidental of
Bangladesh Ltd.) ("OBL"), received from the Bangladesh Oil, Gas & Mineral
Corporation ("Petrobangla") a letter claiming, on behalf of the Bangladesh
government and Petrobangla, compensation allegedly due in the amount of $685
million for 246 BCF of recoverable natural gas allegedly "lost and damaged" in a
1997 blowout and ensuing fire during the drilling by OBL, as operator, of the
Moulavi Bazar #1 ("MB #1") exploration well on the Blocks 13 and 14 PSC area in
Northeast Bangladesh. The Company and OBL believe that the claim vastly
overstates the amount of recoverable gas involved in the blowout.

Consistent with worldwide industry contracting practice, there was no provision
in the PSC for compensating the Bangladesh government or Petrobangla for
resources lost during the contractors' operations. Even if some form of
compensation were due, the Company and OBL believe that settlement compensation
for the blowout was fully addressed in a 1998 Supplemental Agreement to the PSC,
which, among other matters, waived OBL's then 50-percent contractor's share (as
well as the then 50-percent contractor's share held by the Company's Unocal
Bangladesh, Ltd., subsidiary) of entitlement to the recovery of costs incurred
in the blowout, waived their right to invoke force majeure in connection with
the blowout, and reduced by five percentage points their contractors' profit
share (with a concomitant increase in Petrobangla's profit share) of future
production from the sands encountered by the MB #1 well to a drill depth of 840
meters or, if the blowout sand reservoir were not deemed commercial, from other
commercial fields in the Moulavi Bazar "ring-fenced" area of Block 14.
Consequently, the Company and OBL consider the matter closed and OBL has advised
Petrobangla that no additional compensation is warranted.


In view of the inherent  difficulty of predicting  the outcome of legal matters,
the Company cannot state with confidence what the eventual  outcome of the three
preceding  matters will be.  However,  based on current  knowledge,  none of the
preceding matters is presently expected to have a material adverse effect on the
Company's consolidated financial condition or liquidity,  but each of them could
have a material  adverse  effect

                                      -14-



on the Company's  results of operations for the accounting  period or  periods
in which one or more of them  might be  resolved adversely.


Tax matters

The company believes it has adequately provided in its accounts for tax items
and issues not yet resolved. Several prior material tax issues are unresolved.
Resolution of these tax issues impact not only the year in which the items
arose, but also the company's tax situation in other tax years. With respect to
1979-1984 taxable years, all issues raised for these years have now been
settled, with the exception of the effect of the carryback of a 1993 net
operating loss ("NOL") to tax year 1984 and resultant credit adjustments. The
1985-1990 taxable years are before the Appeals division of the Internal Revenue
Service. All issues raised with respect to those years have now been settled,
with the exception of the effect of the 1993 NOL carryback and resultant
adjustments. The Joint Committee on Taxation of the U.S. Congress has reviewed
the settled issues with respect to 1979-1990 taxable years and no additional
issues have been raised. While all tax issues for the 1979-1990 taxable years
have been agreed and reviewed by the Joint Committee, these taxable years will
remain open due to the 1993 NOL carryback. The 1993 NOL results from certain
specified liability losses, which occurred during 1993, and which resulted in a
tax refund of $73 million. Consequently, these tax years will remain open until
the specified liability loss, which gave rise to the 1993 NOL, is finally
determined by the Internal Revenue Service and is either agreed to with the IRS
or otherwise concluded in the Tax Court proceeding. In 1999, the United States
Tax Court granted Unocal's motion to amend the pleadings in its Tax Court cases
to place the 1993 NOL carryback in issue. The 1991-1994 taxable years are now
before the Appeals division of the Internal Revenue Service. The 1995-1997
taxable years are under examination by the Internal Revenue Service.

Pure Resources, Inc. Employment and Severance Agreements

Under circumstances specified in the employment and/or severance agreements
entered into between the Company's Pure subsidiary and its officers, each
covered officer will have the right to require Pure to purchase its common
shares currently held or subsequently obtained by the exercise of any option
held by the officer at a calculated "net asset value" per share. The
circumstances under which certain officers may exercise this right include the
termination of the officer without cause prior to May 25, 2003, termination for
any reason after May 24, 2003, a change in control of either Pure or Unocal and
other events specified in the agreements. The net asset value per share is
calculated by reference to each common share's pro rata amount of the present
value of Pure's proved reserves discounted at 10 percent, as defined, times 110
percent, less funded debt, as defined. At June 30, 2002, Pure estimated that the
amount it may have to repurchase under these agreements was approximately $92
million, which is reflected as subsidiary stock subject to repurchase on the
consolidated balance sheet. The repurchase amount will fluctuate with changes in
the net asset value per share. At December 31, 2001, the repurchase amount under
these agreements was approximately $70 million.

                                      -15-



Other matters

The Company has a lease agreement relating to its Discoverer Spirit deepwater
drillship, with a remaining term of approximately three years and three months
at June 30, 2002. In 2001, the Company signed a sublease agreement with a third
party for a minimum period of 200 days. The completion of the sublease period is
currently estimated to be in September 2002. Under the provisions of the
agreement, the third party assumed all of the lease payments to the lessor
during the sublease period, which began in December 2001. The drillship has a
minimum daily rate of approximately $219,000. The future remaining minimum lease
payment obligation, excluding the remaining sublease period, was approximately
$240 million at June 30, 2002.

In the normal course of business, the Company has performance obligations which
are secured by surety bonds or letters of credit. These obligations primarily
cover self-insurance, site restoration, dismantlement and other programs where
governmental organizations require such support. These surety bonds and letters
of credit are issued by financial institutions but are funded by the Company if
exercised. At June 30, 2002, the Company, including its Pure subsidiary, had
obtained various surety bonds for approximately $350 million. These surety bonds
primarily consisted of bonds for the Company's mining operation discussed in the
following paragraph and a bond for $99 million securing the Company's
performance under a fixed price natural gas sales contract for the delivery of
72 billion cubic feet of gas over a ten year period that began in January of
1999 and will end in December of 2008. The Company also had obtained
approximately $64 million in standby letters of credit at June 30, 2002. The
Company has entered into indemnification obligations in favor of the providers
of these surety bonds and letters of credit. In addition, the Company has
various other guarantees for approximately $410 million. Approximately $200
million of the $410 million in guarantees would require the Company to obtain a
surety bond or a letter of credit, or establish a trust fund if its credit
rating drops below investment grade, that is BBB- or Baa3 from Standard & Poor's
Ratings Services and Moody's Investors Service, Inc., respectively.
Approximately $180 million of the surety bonds, letters of credit and other
guarantees that the Company is required to obtain or issue reflect obligations
that are already included on the consolidated balance sheet in other current
liabilities and other deferred credits. The surety bonds, letters of credit and
other guarantees may also reflect some of the possible additional remediation
liabilities discussed earlier in this note.

As mentioned in the previous paragraph, the Company's Molycorp subsidiary has
permits covering discharges from its Questa, New Mexico, molybdenum mine.
Obtaining these permits involved the posting by Molycorp of two bonds totaling
$152 million that provide financial assurance of completion of temporary closure
plans (required only upon cessation of operations) and other obligations
required under the terms of the permits. These costs are based on estimations
provided by agencies of the state of New Mexico. Unocal has indemnified the
insurance company that issued the bonds with respect to all amounts that may be
drawn against them.

The Company has certain investments in entities that it accounts for under the
equity method, such as Colonial Pipeline Company. These entities have
approximately $1.8 billion of their own debt obligations that are either fully
non-recourse or of limited recourse to the Company. Of the total $1.8 billion in
equity investee debt, $1.1 billion belongs to the Colonial Pipeline Company, in
which the Company holds a 23.44 percent equity interest. The Company guarantees
only $27 million of the total $1.8 billion debt obligations.

The Company also has other contingent liabilities with respect to litigation,
claims and contractual agreements arising in the ordinary course of business. On
the basis of management's assessment of the ultimate amount and timing of
possible adverse outcomes and associated costs, none of such matters is
presently expected to have a material adverse effect on the Company's
consolidated financial condition, liquidity or results of operations.

13.      Financial Instruments and Commodity Hedging

Fair values of debt and other long-term instruments - The estimated fair value
of the Company's long-term debt at June 30, 2002, including the current portion,
was approximately $3.31 billion. The fair value was based on the discounted
amounts 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 approximately $527 million at
June 30, 2002. The fair value was based on the trading prices of the preferred
securities on June 28, 2002, as reported to the Company.

Commodity hedging activities - During the second quarter of 2002, the Company
recognized $1 million in after-tax losses for the ineffectiveness of both cash
flow and fair value hedges. For the six months ended June 30, 2002, the earnings
impact of ineffectiveness was immaterial. At June 30, 2002, the Company had
approximately $9 million of after-tax deferred losses in accumulated other
comprehensive income on the consolidated balance sheet related to cash flow
hedges for future commodity sales for the period beginning July 2002 through
October 2004. Of this amount, approximately $3 million in after-tax losses are
expected to be reclassified to the consolidated earnings statement during the
next twelve months.

Foreign currency contracts - At June 30, 2002, the Company had approximately $1
million of after-tax deferred gains in accumulated other comprehensive income on
the consolidated balance sheet related to cash flow hedges for future foreign
currency denominated payment obligations through December 2003. Of this amount,
the losses expected to be reclassified to the consolidated earnings statement
during the next twelve months are immaterial.

Interest rate contracts - At June 30, 2002, the Company had approximately $3
million of after-tax deferred losses in accumulated other comprehensive income
on the consolidated balance sheet related to cash flow hedges of interest rate
exposure through September 2012. Of this amount, the losses expected to be
reclassified to the consolidated earnings statement during the next twelve
months are immaterial.

14.      Supplemental Condensed Consolidating Financial Information

Unocal guarantees all the publicly held securities issued by its 100
percent-owned subsidiaries Unocal Capital Trust and Union Oil. Such guarantees
are full and unconditional and no subsidiaries of Unocal or Union Oil guarantee
these securities.

The following tables present condensed consolidating financial information for
(a) Unocal (Parent), (b) the Trust, (c) Union Oil (Parent) and (d) on a combined
basis, the subsidiaries of Union Oil (non-guarantor subsidiaries). Virtually all
of the Company's operations are conducted by Union Oil and its subsidiaries.

16.      Subsequent Event

In July 2002, the Company's Unocal Geothermal of Indonesia, Ltd. ("UGI")
subsidiary and Dayabumi Salak Pratama, Ltd. ("DSPL"), a 50-percent equity
investee of UGI, reached agreement over pricing and production issues at its
Gunung Salak geothermal project in Indonesia with PT. PLN (Persero) ("PLN"), the
Indonesian state-owned electricity company, and Pertamina, the Indonesian
state-owned oil and natural gas company. The new agreement extends the primary
terms of the Joint Operation Contract and Energy Sales Contract ("ESC") to 2040
and also contains provisions to extend the deadline for transferring to PLN
generating plants currently operated by DSPL plus any additional plants
subsequently developed and operated by DSPL or the Company to the expiration
date of the ESC. The new agreement lowers the selling price of electricity
delivered by DSPL from 8.49 cents per kilowatt-hour (kWh) to 4.45 cents per kWh
and steam supplied to PLN by UGI from 4.25 cents per kWh to 3.75 cents per kWh.
Under the terms of the amended ESC both the selling price for electricity and
the selling price for geothermal steam are indexed for changes in foreign
exchange rates and inflation. The new agreement also provides for payment by PLN
of a portion of the past due receivable balances to the Company while the
Company foregoes a portion of the receivables.
