Dear Stockholder:

     Please accept my personal invitation to attend our Annual Meeting of
Stockholders on Monday, May 19, 2003. It will be held in the auditorium at the
Company's Hartley Center, 376 South Valencia Avenue in Brea, California, at
10:00 A.M. to elect four directors, ratify the appointment of independent
accountants, and vote on two stockholder proposals. Before the conclusion of the
Meeting, there will be a period for questions and comments.

     If you are a registered stockholder and plan to attend the Stockholders'
Meeting, please mark the attendance box on your proxy card and bring the
tear-off admission ticket with you to the Meeting. If you are a beneficial owner
of Unocal stock held by a bank, broker or other nominee (with your stock held in
"street name"), you will need proof of ownership to be admitted to the Meeting.
A recent brokerage statement or a letter from the bank or broker are examples of
proof of ownership. Stockholders will be asked for identification for admission
to the Meeting.

     Your vote is important. I urge you to submit your proxy as soon as possible
so that your shares will be represented. Again this year, most stockholders have
their choice of three methods to vote by proxy:

        o        Mail, using the enclosed proxy card and return envelope
                 ----
        o        Phone, using the 800 number provided on the proxy card
                 -----
                 (U.S. and Canada only), or
        o        Internet, using the website provided on the proxy card.
                 --------

     Thank you very much for your continued interest and support.

                                         Sincerely,


                                         /s/ Charles R. Williamson

                                             By Order of the Board of Directors

                                             Proxy Statement


                          UNOCAL [LOGO APPEARS HERE]



                                             Unocal Corporation
                                             2141 Rosecrans Avenue, Suite 4000
                                             El Segundo, California 90245

     This proxy statement is furnished in connection with the solicitation of
proxies by the Board of Directors of Unocal Corporation (the "Company" or
"Unocal"), a Delaware corporation, for use at the 2003 Annual Meeting of
Stockholders of the Company to be held on May 19, 2003, and any adjournment
thereof, pursuant to the notice of the Meeting.

     The notice of the Annual Meeting and this proxy statement, together with a
proxy card and the Company's 2002 Annual Report, are being sent to stockholders
on or about April 7, 2003.

     Only common stockholders of record on the books of the Company at the close
of business on March 20, 2003, are entitled to vote at the Meeting. A
stockholder of record is entitled to one vote for each share of common stock
owned. As of February 28, 2003, the Company had 258,013,728 shares of common
stock outstanding. Under Delaware law, shares voted by brokers as to
discretionary matters only and shares abstaining will be counted as present for
the purpose of determining whether there is a quorum. With regard to the
election of directors, votes that are withheld will be excluded entirely from
the vote and will have no effect. Abstentions on Item 2 (ratification of the
appointment of independent accountants), and Items 3 and 4 (stockholder
proposals) will have the effect of negative votes. Pursuant to the rules of the
New York Stock Exchange, only Items 3 and 4 (stockholder proposals) are
"non-discretionary." Brokers who do not receive instructions from their clients
will not have discretion to vote on Items 3 and 4, and these broker "non votes"
will not be counted as votes cast for determining their outcome.


                               GENERAL INFORMATION

     The Unocal Board of Directors is soliciting this proxy. The Company will
pay the cost of soliciting proxies. In addition to solicitation by mail, certain
directors, officers and employees of the Company and its subsidiaries may
solicit proxies by telephone, personal interview, electronic mail, facsimile and
other written communication. The Company also has retained D. F. King & Co.,
Inc., New York, New York, to assist in the solicitation of proxies for a fee
estimated to be $16,500, plus reimbursement of out-of-pocket expenses. The Board
of Directors has appointed Messrs. Timothy H. Ling and Charles O. Strathman as
the proxy holders for the Annual Meeting.

     All stockholders may vote by signing, dating and returning their proxy
cards in the enclosed pre-addressed envelopes. Registered stockholders may
instead choose to vote by telephone (from U.S. and Canada locations), using the
toll-free number listed on the proxy card, or electronically on the Internet,
using the web site listed on the proxy card, or in person at the Meeting. If you
are a beneficial owner of Unocal stock held by a bank, broker or other nominee
(with your stock held in "street name"), please read your voting card to
determine whether you may vote by telephone or electronically on the Internet,
following the instructions on the card. A street-name stockholder who wishes to
vote at the Meeting will need to obtain a proxy from the record holder.

                                       1



     A registered stockholder who has provided a proxy may revoke it at any time
before the shares are voted at the Meeting by executing a later-dated proxy, by
providing new instructions using the proxy telephone or Internet system, by
voting by ballot at the Meeting, or by filing an instrument of revocation with
the Inspector of Elections. The proxy tallying agent will record your vote
according to the instructions which it receives last, regardless of when you
transmitted the instructions.

     The Board of Directors wishes to encourage stockholder participation in
corporate governance by its policy of ensuring the confidentiality of
stockholder votes. The Company retains independent third parties to receive and
tabulate stockholder votes. The manner in which any stockholder votes on any
particular issue shall, subject to federal or state law requirements, be
strictly confidential.

     The Board of Directors considers that some registered stockholders may want
the Company to know how they have voted and the Company, where possible, may
wish to inquire as to how stockholders have voted. If you want the Company to
have access to your proxy card, you may check the box marked "OPEN BALLOT" on
the proxy card and your proxy will be made available to the Company. Your vote
will remain confidential if you do not check the "OPEN BALLOT" box.

     Registered stockholders who have computer access to the World Wide Web on
the Internet and agree to receive future annual reports and proxy statements by
accessing the Company's web site should check the "Electronic Delivery" box on
the proxy card. If you check this box, we will inform you of the web address to
access these documents electronically, and we will not mail paper copies of
future annual reports and proxy statements to you unless you request paper
copies.

     Most banks and brokers are delivering only one copy of the annual report
and proxy statement to consenting street-name stockholders who share the same
address. This saves the Company money in printing and distribution costs. Those
banks and brokers will continue this practice unless they receive contrary
instructions from one or more of the stockholders within the household.

     Street name stockholders in a single household who received only one copy
of their annual meeting materials can request to receive separate copies in the
future by contacting their bank or broker. In most cases, they may also do so by
checking the appropriate box on the voting instruction card sent to them.
Similarly, most street-name stockholders who are receiving multiple copies of
the annual report and proxy statement at a single address may request that only
a single set of materials be sent to them by checking the appropriate box on the
voting instruction card sent to them, or by contacting their bank or broker.

     Rather than contacting their bank or stockbroker directly, most street-name
stockholders may give instructions to receive separate copies or discontinue
multiple mailings of materials by contacting the third party that mails annual
meeting materials for most banks and brokers by writing to Householding
Department, ADP, 51 Mercedes Way, Edgewood, NY 11717, or telephoning (800)
542-1061. Alternatively, stockholders may send written instructions to Unocal
Stockholder Services, 2141 Rosecrans Avenue, Suite 4000, El Segundo, CA 90245,
and the Company will forward your instructions. In both cases, your instructions
must include the name of your stockbrokerage firm and your account number.
Please note that some banks and stockbrokers do not follow the practice of
sending only one copy of the annual meeting materials to consenting stockholders
sharing the same address.

     Copies of the current annual report and proxy statement are available by
contacting Unocal Stockholder Services at (310) 726-7681, 2141 Rosecrans Avenue,
Suite 4000, El Segundo, CA 90245, fax (714) 985-6363, e-mail:
stockholder_services@unocal.com.

     Registered stockholders will receive one proxy statement and annual report
for each account. Registered stockholders who would prefer to view annual
reports and proxy statements on the internet may request electronic delivery as
explained above.

                                     ITEM 1.
                              ELECTION OF DIRECTORS

     The Board of Directors is divided into three classes. Directors in each
class are normally elected for three-year terms or until their successors are
duly elected and qualified. This year, there are four director nominees for
three-year terms expiring at the annual meeting in 2006. Information about the
four director nominees and the six continuing directors, whose terms expire in
2004 and 2005, is provided in the table below.

     The Company's director retirement policy requires that a director retire on
the day of the annual meeting of stockholders following the director's 72nd
birthday; thus, John W. Amerman would retire in 2004 and John W. Creighton, Jr.
would retire in 2005, even though they are in the class of directors whose terms
expire in 2006.

     If any nominee becomes unavailable or disqualified to serve as a director,
and if the Board designates a substitute nominee, the proxy holders will vote
for the substitute nominee designated by the Board.

DIRECTORS' COMPENSATION

CASH COMPENSATION AND EXPENSES

     Non-employee directors receive the following fees and reimbursement of
expenses:

     o $25,000 annual retainer for serving as a director
     o $25,000 annual retainer for serving as Vice-Chairman of the Board
     o $6,000 annual  retainer for chairing a committee  other than the Audit
       Committee
     o $15,000 annual retainer for chairing the Audit Committee
     o $3,000 per day for each Board meeting attended
     o $1,000 for each committee meeting attended
     o Reimbursement of reasonable out-of-pocket expenses related to meetings
       and other Company business

     From January through November, 2002, there was no Vice-Chairman position,
 and the annual retainer for chairing the Audit Committee was $6,000. The
 retainers are paid in monthly installments.

STOCK COMPENSATION

     The 2001 Directors' Deferred Compensation and Stock Award Plan (the "Plan")
was approved by the stockholders at the 2001 annual meeting. A total of 500,000
shares are authorized for issuance for awards made under the Plan through July
1, 2006. Under the Plan, each non-employee director receives:

     o An annual  grant of stock units  equal in value to 20 percent of the
       Director's  fees  earned  during the prior year
     o An initial stock option award with a value of $82,500 upon first being
       elected to the Board
     o An annual stock option award with a value of $27,500
     o For any cash fees voluntarily deferred, stock units equal to 120% of the
       cash deferred

     The Board Governance Committee (the "Governance Committee") administers the
Plan. The Governance Committee has broad authority under the Plan, including the
authority to establish the valuation methodology that determines the number of
shares underlying option grants, within plan limits. The Governance Committee
may also determine adjustments to plan terms responsive to extraordinary
transactions, and establish, adopt and revise rules and regulations relating to
the plan. For the 2002 annual stock option awards, and for Ferrell P. McClean's
initial stock option award, the numbers of shares underlying the stock option
grants were determined using a Black Scholes model that resulted in a formula
that multiplied the fair market value of a share of common stock on the grant
date by .3877 and then divided the award value by the result.


                                       8



     The following annual stock option awards and initial stock option award
were granted to non-employee directors in 2002 under the Plan:

     Stock options granted under the Plan are 10-year nonqualified stock
options. The exercise price of the options is the fair market value of the
shares on the date of grant. Initial option grants vest 33 1/3% each year over
three years, and annual option grants vest 50% each year over two years. Options
become immediately vested upon: (1) death or disability; (2) a Change in
Control; or (3) with respect to options that have been outstanding for at least
nine months, retirement from service either (A) at the end of the director's
then current term and after completing five full years of service, if a director
is ineligible to stand for reelection under the Company's director retirement
policy, or (B) on the date of the Annual Meeting of Stockholders immediately
following the director's 72nd birthday under the Company's director retirement
policy and after completing five full years of service. A director who
terminates service for any reason other than for cause will have three years to
exercise vested options if the director served on the Board for at least three
years, and two years to exercise vested options if the director served on the
Board less than three years.

     Stock units represent unfunded bookkeeping entries, which are paid out in
an equal number of shares of common stock at the end of the deferral period
chosen by each Director for each annual grant or voluntarily deferred annual
compensation. The units are fully vested and non-forfeitable at all times.
Dividend equivalents are credited as additional stock units, subject to the same
deferral elections.

     The minimum deferral period that may be elected for stock units is three
years or following a termination of services, whichever is earlier or later. In
addition, participants may elect to accelerate the payout of their units upon a
Change in Control, upon certain hardships, or by requesting an early
distribution, subject to a withdrawal penalty. Payout of units occurs if a unit
holder would otherwise forfeit the units as a result of acceptance of government
or community service.

     Subject to customary exceptions, stock options and stock units are
generally non-transferable, except by will or the laws of descent and
distribution or beneficiary designation. The Governance Committee, however, may
permit certain transfers of stock options for estate and/or tax planning
purposes to certain related persons or entities.

                             EXECUTIVE COMPENSATION

        REPORT OF THE MANAGEMENT DEVELOPMENT AND COMPENSATION COMMITTEE

This report of the Management Development and Compensation Committee of the
Board of Directors (the "Committee") describes the executive compensation
programs and policies of the Company, including its short-term and long-term
incentive compensation plans. Key elements of the compensation program are:

o    Compensation Committee members are independent, non-employee directors

o    Salaries  are based on  comparisons  with  petroleum  and  energy  industry
     medians

o    Long-term incentives use absolute and/or relative stock performance

o    Short-term  incentives  use a combination of stock  performance,  financial
     performance, individual performance and operational results

o    The peer group of companies was changed for 2003 to reflect  changes in the
     petroleum industry

o    Committee retains and is assisted by an outside consultant.

         The Committee, composed entirely of independent, non-employee
directors, is responsible for setting and administering the annual and long-term
compensation programs. The Committee reviews and determines executive officer
salaries and incentive awards under the 1998 Management Incentive Program. The
Committee also administers the 2000 Executive Stock Purchase Program. The
Committee is assisted by an outside consultant, and has delegated certain
administrative responsibilities with respect to salaries and incentive awards
for non-executive officers to the Chairman and Chief Executive Officer (the
"CEO"). The outside consultant and the CEO are present at Committee meetings but
cannot vote. The Committee considers competitive compensation data, Company
performance and individual performance, including adherence to the Company's
Code of Conduct, in establishing executive compensation. The Committee meets
outside the presence of the CEO on certain matters, including CEO compensation
and certain succession issues. The Committee met five times in 2002.

         The compensation program for the CEO and other executives consists of
four elements: salary, annual cash bonus, performance share awards and stock
options. All of these elements, other than salary, are part of the Management
Incentive Program. Each element of executive compensation is discussed below.

         The Management Incentive Program, consisting of the Revised Incentive
Compensation Plan and the Long-Term Incentive Plan of 1998, was developed to
reinforce the goal of creating value for the stockholders. The Program, approved
by the stockholders in 1998 and subsequently amended with stockholder approval
in 2000 and 2002, explicitly links short-term and long-term incentive
compensation to the Company's common share price performance.

         In addition to absolute share price appreciation, some of the
components of the Company's executive compensation program use relative share
price performance. The "Comparative Return to Shareholders" compares the
Company's share price, plus dividends (Total Shareholder Return or "TSR") to
that of a group of companies in energy-related businesses (the "Peer Group").

         The Peer Group is designed to have a composite business mix that is
similar to that of the Company as of the beginning of an award period.
Therefore, the effects of commodity prices and other external events should be
similar for the Company and the Peer Group, taken as a whole. The companies
comprising the Peer Group are reviewed periodically and changed as business
characteristics of these



                                       12


companies, and of Unocal, change. Once the Peer Group
is established for a particular award, it is not altered for the award period.
If a company in the Peer Group does not continue as a public company to the end
of an award period, the calculation uses the average share price 60 days prior
to the merger or other corporate transaction which resulted in such company no
longer being listed on a stock exchange. The Peer Group for 2002 awards under
the Management Incentive Program consisted of 15 companies that, as a group,
reflected Unocal's current lines of business. For 2003 Awards, two companies
were added and six companies were deleted, resulting in a Peer Group of 11
companies. These changes reflected continuing restructuring in the petroleum
industry and the growing importance of Unocal's international operations.

         It is the Committee's belief and intention that applicable executive
incentive compensation paid or accrued in 2002 under the Management Incentive
Program will be fully deductible as performance-based compensation under the
requirements of Section 162(m) of the Internal Revenue Code.

SALARY

         The base salaries of the CEO and the other executive officers are
reviewed annually and when there is a significant change in an executive's
responsibilities. The Committee considers the responsibilities, experience and
performance of the executive officers and survey data on the compensation paid
by energy and petroleum-related companies for similar positions. For 2002, the
Committee selected a group of 11 companies to use to compare salary and other
compensation (the "Compensation Group"). All of these companies were also part
of the Peer Group used for calculating Comparative Return to Shareholders in
2002, but four companies in the Peer Group were not included either because of
their size or because they were non-U.S. companies. Following a review of
compensation data in 2002, the salary of the CEO, Mr. Williamson, was increased
to $836,000 in July, 2002.

         The objective of the Committee is to establish base salaries that are
near the median paid by the companies in the Compensation Group, with
adjustments for reporting relationships, responsibilities and job scope. After
increases to the base salary of the executive officers for 2002, the salaries of
those officers as a group and that of the CEO were at approximately the
estimated median of comparative salaries of the surveyed companies.

UNOCAL DEFERRED COMPENSATION PLAN

         The Unocal Deferred Compensation Plan (the "DCP"), adopted in 2001,
allows participants to defer up to 90% of annual bonuses and up to 50% of
salary. The participant may elect various investment options, which determine
the ultimate payment due at the end of the elected deferral period. The DCP is
largely unfunded and the participants are unsecured creditors of the Company.

REVISED INCENTIVE COMPENSATION PLAN

         The Revised Incentive Compensation Plan (the "RICP") is the Company's
annual bonus plan for senior and middle management. Each award period under the
Plan is one year. The annual bonus pool for a calendar year equals 2% of the
Company's "Net Cash Provided by Operating Activities," which is the maximum
amount of annual cash bonuses that may be awarded in a calendar year.

         Prior to March of each year, the Committee establishes a percentage of
this bonus pool as the maximum target award for the CEO and certain other
executive officers. The Committee also establishes individual target awards for
the remaining participants based on salary grade.

         For 2002, the Committee approved a bonus award payout based 25% on
Comparative Return to Shareholders, 37.5% on financial performance ("Return on
Capital Employed" and "Free Cash Flow") and 37.5% on an evaluation of the
calendar year activities that will affect future performance. The Committee

                                       13



determined that the Company performed below the established goals with respect
to the financial and future performance measures, while the Company's TSR was at
the 15th percentile of the Peer Group, resulting in no payout with respect to
this factor. Consequently, for 2002 the bonus award pool for the entire eligible
group was set at 52% of the target amount. Awards were subject to further
adjustment to reflect business unit and individual performance.

         The RICP provides for deferral of awards into restricted stock and
awards can also be deferred under the DCP as described above. The portion of the
award deferred into restricted stock is increased by 20% to compensate for the
executive foregoing immediate cash compensation and for the risk of forfeiture.
The restriction period is five years. The award is forfeited if the recipient
resigns or is terminated for cause prior to the end of the restriction period,
unless the recipient retires at or after age 65. Mr. Williamson deferred 90% of
his award into the DCP. The Company's other five named executive officers
deferred an average of 10% of their awards into restricted stock and 38% into
the DCP.

EXECUTIVE STOCK PURCHASE PROGRAM

         The Executive Stock Purchase Program was approved by stockholders at
the 2000 Annual Meeting. Mr. Williamson and nine other participants (including
three named executive officers) received interest-bearing, full recourse loans
to purchase shares of Unocal common stock. Since the executives invest in shares
of the Company, the Program links their interests with other stockholders by
having the executive's assets subject to the risks and rewards of Unocal stock
ownership. Interest on the executive loans accrues at an annual rate of 6.8%.
Dividends on shares held by the participant must be used to repay loan balances.
While participants can elect to repay the loan and accrued interest at any time,
full repayment of principal and accrued interest is not due until March, 2008.

         The program resulted in the participants acquiring 1,150,310 shares of
stock, thus aligning their interests with those of other stockholders. Mr.
Williamson acquired 179,737 shares of Unocal stock and had an outstanding loan
balance of $5.6 million on December 31, 2002. Each of the participants was also
granted a Performance Bonus Award, as described below. In February 2002, the
Committee decided that no additional loans would be made and cancelled the
authorization for the remaining 599,690 shares reserved under the Program for
future issuance.

LONG-TERM INCENTIVE PLAN

         The Long-Term Incentive Plan of 1998, as amended (the "1998 Plan"), is
administered by the Committee and provides for awards in the form of
non-qualified stock options, performance shares, performance bonus awards and
restricted stock. The previous plan, The Long-Term Incentive Plan of 1991 (the
"1991 Plan"), also provided for grants of non-qualified stock options,
performance shares and restricted stock.

         In 2000, the stockholders approved Performance Bonus Awards under the
1998 Plan. Performance Bonus Awards were made only to participants in the
Executive Stock Purchase Program. Performance Bonuses are payable based on the
Company's comparative TSR and absolute share price. Determination of whether
these factors will result in any payment will be made as of December 31, 2003.
Based on the Company's TSR and absolute share price as of December 31, 2002, if
the award period had ended on such date, no performance bonuses would have been
payable.

         The Committee awarded a "target" number of performance share units in
1999 to the CEO and other executive officers for the 1999 - 2002 performance
period under the 1998 Plan. Each unit is the equivalent of one share of the
Company's common stock. The awards are dependent on the executive's level of
responsibility and base compensation. Mr. Williamson's award for this
performance period was 5,000 units.

                                       14


         The actual payout of awards at the end of the four-year performance
period is determined by how the Company's TSR for the period compares to that of
the Peer Group. The maximum number of shares that can be paid out is 200% of the
performance share units granted, and the maximum value of the payout cannot
exceed 400% of the Fair Market Value of the initial award. During the 1999 -
2002 performance period, the Company's TSR was significantly below the average
of the Peer Group. Therefore, none of the performance share units awarded were
paid out to the participants, including Mr. Williamson.

         Option grants are normally made in February or March of each calendar
year. Prior option grants are not considered in making these awards except when
a grant is in lieu of future grants. The number of options granted to the
executive officers is determined by reviewing option grants for similar
positions by the surveyed companies. The compensation value of the option grants
to the executive officers as a group is also compared to option grants and
compensation data available from the proxy statements of other large public
companies. The option exercise price under the 1998 Plan is the fair market
value on the date of grant. Exercise of an option results in compensation to the
employee only if the fair market value on the date of exercise exceeds the price
on the date granted.

         Currently, the only numerical restrictions on grants are the total
number of shares available under the 1998 Plan and the limitation that no person
may be granted during any 12-month period options to acquire more then 600,000
shares. In 2001 the Company made four grants, including an option for 450,000
shares to Mr. Williamson and options to purchase 630,000 shares to three other
named executive officers. These grants were made after reviewing competitive
data and were intended to provide an immediate incentive to the executive to
maximize share price performance by granting three years of options at one time.
Since these grants were for a three-year period, these individuals did not
receive option grants in 2002, and they are ineligible for option grants in 2003
and 2004.

         Since the total number of shares available under the 1998 Plan is less
than five percent of the outstanding shares, individual grants during the term
of the 1998 Plan have not been of such magnitude as to have any significant
dilutive effects on the Company's stock.

         As described above, Unocal aligns management and stockholder interests
by linking executive incentive compensation programs to share price performance
and the creation of stockholder value. The 1998 Long-Term Incentive Plan also
provides for grants of restricted stock to executives, managers and technical
employees whose performance and potential is exceptional. The award is forfeited
if the recipient resigns or is removed for cause prior to the end of the
restriction period. In addition, the Company has incentive programs for other
employees that focus on contributions to the success of the Company and its
stockholders, including an Annual Incentive Plan, Chairman's Awards and Special
Recognition Awards.

(A)  The options were granted pursuant to the Long-Term Incentive Plan of 1998.
     The options become exercisable in four equal installments 6 months, 1 year,
     2 years and 3 years from the date of grant. The exercise price of the
     options is the average of the highest and lowest trading prices of
     transactions in Unocal common stock as reported in the New York Stock
     Exchange Composite Transactions for the date of grant. The maximum option
     exercise period is ten years from the date of grant. The optionees may pay
     for option stock with cash, Unocal common stock they already own, or with
     proceeds from the sale of common stock acquired by exercise of the option
     through authorized cashless exercise procedures with stock brokers. Vesting
     of options ceases upon termination of employment. Upon a change of control
     (as defined in the option agreements), any unvested options would vest. The
     options cease to be exercisable upon termination of employment, with the
     following exceptions: a participant who retires at or after age 65, upon
     permanent and total disability, or under conditions determined by the
     Management Development and Compensation Committee to be for the convenience
     of the Company, is granted three years in which to exercise vested options.
     Beneficiaries have 15 months to exercise vested options upon death of the
     option holder. Options are nontransferable except in the event of the
     employee's death or pursuant to a court order, unless the Committee, in its
     sole discretion, permits transfers to the employee's family members and
     entities established for or owned by family members.

(B)  The number of securities  underlying all options  granted to employees
     in 2002: 1,782,442.

(C)  Use of the assumed stock price appreciation of 5% and 10% each year for the
     option period is specified in Securities and Exchange Commission Regulation
     S-K. No valuation method can accurately predict future stock price or
     option values because there are too many unknown factors. If the stock
     price does not increase above the exercise price, the options will have no
     value.

(A)  Pursuant  to the  performance  shares  agreements,  the  actual  number  of
     performance   shares  paid  out  is  based  on  the  Company's   return  to
     stockholders for the four-year  performance period (January 1, 2002 through
     December 31, 2005) compared to that of a group of peer  companies  selected
     by  the  Management  Development  and  Compensation  Committee.  Return  to
     stockholders  is  defined  as  share  price   appreciation  plus  dividends
     expressed as a percentage of the beginning share price.  The maximum number
     of shares that can be paid out is 200% of the  performance  shares granted,
     and the maximum  value of the payout  cannot exceed 400% of the Fair Market
     Value  of  the  initial  award  of  performance   shares.   The  Management
     Development  and  Compensation  Committee  may reduce the payment  based on
     other factors at the  discretion of the  Committee.  If Unocal's  return to
     stockholders  is at or under the 30th percentile of the peer group's return
     to stockholders,  there is no payout.  The payout percentage may not exceed
     50% if  Unocal's  return  is at the 35th  percentile  of the  peer  group's
     return,  the payout may not exceed 100% if  Unocal's  return is at the 60th
     percentile of the peer group's  return,  and the payout  percentage may not
     exceed  200% if  Unocal's  return  is at the 100th  percentile  of the peer
     group's  return.  A matrix  is used for  determining  the  specific  payout
     percentages  that may not be exceeded for specific  return to  stockholders
     levels between the 30th and 100th percentile. Awards can be paid out partly
     in cash and partly in shares,  as determined by the Management  Development
     and Compensation Committee.

(B)  Mr. Codon ceased being an executive officer on December 3, 2002. Any payout
     will be  prorated  for the  length  of his  service  during  the  four-year
     performance period.

(A)  Covered compensation is the average monthly compensation in the 36
     highest-paid months out of the last 120 months immediately preceding
     retirement. For the named executive officers in the Summary Compensation
     Table on page 17, covered compensation equals the amounts in the Salary and
     Bonus columns of the Summary Compensation Table and the amount of bonus
     that the participant elected to defer into restricted stock (other than
     augmentations for deferring into restricted stock).



     The Company has a noncontributory qualified defined benefit retirement plan
covering substantially all U.S. payroll employees. The plan provides
participants with retirement benefits based on a formula relating such benefits
to compensation and years of service, less up to half of the estimated old age
Social Security benefit payable. The amount of these benefits is limited by the
Employee Retirement Income Security Act of 1974 and the Internal Revenue Code.
Where that occurs, the Company has nonqualified retirement plans designed to
maintain total retirement benefits at the qualified plan formula level. The
plans exclude augmentations to bonuses deferred into restricted stock, and
interest and appreciation in the value of bonuses and/or salary deferred into
the Unocal Deferred Compensation Plan. This Pension Plan Table, which covers all
persons named in the Summary Compensation Table, shows the estimated annual
benefits from the plans, before the deduction for a portion of the estimated old
age Social Security benefit, as described above. The benefits shown are computed
based on a single life annuity payable at normal retirement age.

     Covered compensation and credited full years of service under the
retirement plan as of year-end 2002 for the executive officers named in the
Summary Compensation Table are as follows: $1,167,480 and 25 years for Mr.
Williamson; $974,776 and 5 years for Mr. Ling; $364,236 and 1 year for Mr.
Dallas; $525,393 and 28 years for Mr. Codon; $364,766 and 22 years for Mr.
Strathman; and $333,957 and 31 years for Mr. Cecil.

               EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND
                         CHANGE OF CONTROL ARRANGEMENTS

     The Company has employment  agreements  with Messrs.  Williamson and Dallas
that are effective for three years. These agreements  automatically  renew daily
until the Company gives notice that it does not wish to further extend the term,
but in no event later than the date of the Company's  annual  meeting  following
the  employee's  65th  birthday.  The  agreements  provide for certain  benefits
following an employment  termination without cause or following an alteration of
the employee's employment situation, as defined in the agreements (collectively,
a "Termination Without Cause"),  including a payment of 3.18 times annual salary
plus three times target  bonus  applicable  as of the  beginning of the calendar
year in which such Termination  Without Cause occurs, as well as continuation of
medical,  dental, life and disability insurance coverage for two years following
the Termination Without Cause. In lieu of the

                                       22


foregoing continued medical,  dental, life and disability benefits,  the Company
may elect to pay the sum of $25,000. In the event of a Termination Without Cause
within 24 months of a Change of Control (as defined in the  agreement),  Messrs.
Williamson  and Dallas  would also be entitled  to the  increase in the lump sum
value  of  their  benefits  under  the  Company's  qualified  and  non-qualified
retirement plans, as if three years were added to their benefit service and ages
thereunder.  If any payment or distribution by the Company  ("Payment") would be
subject to the excise tax imposed by Section 4999 of the Internal  Revenue Code,
or any interest or penalties  are incurred with respect to such excise tax (such
excise tax and any such interest and penalties, collectively, the "Excise Tax"),
then the employee is entitled to an additional payment (a "Gross-Up Payment") in
an amount such that after  payment by the employee of all taxes  (including  any
interest or penalties imposed) and Excise Tax imposed upon the Gross-Up Payment,
the employee  retains an amount of the Gross-Up  Payment equal to the Excise Tax
imposed  upon the  Payments.  If  distributions  and  payments to be made by the
Company do not exceed 110% of the greatest  amount (the  "Reduced  Amount") that
could be paid to Messrs. Williamson or Dallas, such that the receipt of payments
would not give rise to any Excise tax, then no Gross-Up Payment will be made and
the payments will be reduced to the Reduced  Amount.  Messrs.  Williamson's  and
Dallas's  agreements  were filed as exhibits to the  Company's  Annual Report on
Form 10-K for the year ended December 31, 2002.

     The Company has a change in control agreement with Mr. Ling that is
effective for three years, renewing daily until the date that the Company gives
notice that it does not wish to further extend the term. The agreement provides
that in the event of a Termination Without Cause within 36 months following a
Change of Control that occurred during the term of the agreement, Mr. Ling will
be entitled to the same benefits as provided in the employment agreement for Mr.
Williamson described above. The agreement was filed as an exhibit to the
Company's Annual Report on Form 10-K for the year ended December 31, 2002.

     The Company also has an employment agreement with Mr. Strathman which
provides that if his employment is terminated (a) by the Company, at any time
for reasons other than misconduct, or (b) by the Company or as a result of Mr.
Strathman's resignation, (i) after May 31, 2004 for any reason, (ii) any time
after six months following the appointment of a new Chief Legal Officer/General
Counsel, or (iii) following a reduction of his salary or incentive targets, then
his termination shall be treated as "at the convenience of the Company" under
the Company's long-term incentive plans, thus entitling him to the extended
period provided therein to exercise vested stock options, the vesting of
restricted stock, the pro-rata payment of performance shares and a Revised
Incentive Compensation ("ICP") award for calendar years 2003 and 2004, prorated
for his actual period of employment. Under such a termination he will also be
entitled to such severance and termination-type benefits applicable to his
position, including, at a minimum, Unocal Employee Redeployment Program and
Unocal Termination Allowance Plan benefits. The agreement was filed as an
exhibit to the Company's Current Report on Form 8-K dated February 4, 2003.

     The Company has an agreement with Mr. Codon relating to his resignation as
an officer and to his retention as a consulting employee through September 30,
2003 (or earlier if he accepts conflicting employment). During such period, Mr.
Codon will continue to be paid his current salary, accrue retirement benefits
and continue to be eligible for all of the Company's benefit plans generally
applicable to a full-time employee at his salary grade, provided that he will
not receive any severance-type benefits or benefits under his prior employment
agreement. Thereafter he will be eligible for all retiree health and welfare
benefits generally applicable to an employee in his employment category. Under
the agreement, Mr. Codon was paid the sum of $1,415,522, the value of his
accrued vacation, his account balances under the Supplemental Savings Plan, the
deferred cash portion of his ICP awards, and will be eligible to receive
financial counseling services at Company expense through December 31, 2003. For
calendar year 2002 he will be eligible to receive an ICP Award based on the
percentage of target awards payable to corporate department employees of the
Company in his salary grade based on Company performance without any adjustment
for individual performance. For calendar year 2003 he will be entitled to the
greater of (a) 75% of the ICP Award that would be payable to a corporate
department employee in his salary grade, based on Company performance but
without any adjustment for individual performance, or (b) 75% of the target ICP
Award for an employee in his salary grade, without adjustment for Company or


                                       23



individual performance. In the event of the announcement of a "Change of
Control" (as defined in the Long-Term Incentive Plan of 1998) prior to October
1, 2003, which is consummated prior to October 1, 2005, Mr. Codon shall receive
the sum of $911,970 within 60 days of said Change of Control. The agreement
provides that Mr. Codon will be entitled to an extended period to exercise
vested stock options, the vesting of restricted stock and the pro-rata payment
of performance shares, under the Company's long-term incentive plans, and
retains the original payment schedule for amounts due under his March 16, 2000
loan to purchase shares of common stock of the Company under the 2000 Executive
Stock Purchase Program. The agreement was filed as an exhibit to the Company's
Current Report on Form 8-K dated December 3, 2002.

     In the event of a "change in control," as defined in the Company's
incentive plans and agreements issued thereunder, annual cash bonuses will be
paid, restricted stock will become vested, unvested options will become vested,
and payout will be accelerated for performance shares and Performance Bonus
Awards under the Long-Term Incentive Plan of 1998. Performance shares will be
paid out at not less than the target number of shares, subject to the limitation
that the fair market value of the shares paid out may not exceed 400% of the
fair market value of the initial award of performance shares. The payout for
Performance Bonus Awards will in no event be less than 50% of the maximum amount
awardable thereunder. Annual cash bonuses under the Revised Incentive
Compensation Plan will pay out at not less than the target amount, prorated by
the ratio that the shortened award period bears to the calendar year. At
February 28, 2003, 1,197,031 shares of restricted stock were outstanding,
unvested options to purchase 4,540,640 shares of common stock were outstanding
at a weighted average exercise price of $30.66, and 836,645 performance shares
were outstanding. At February 28, 2003, the number of shares of restricted stock
outstanding for the named executive officers were: Mr. Williamson, 17,371
shares; Mr. Ling, 38,132 shares; Mr. Dallas, 2,062 shares; Mr. Codon, 10,272
shares; Mr. Strathman, 2,253 shares; and Mr. Cecil, 4,786 shares. Unvested
options outstanding at December 31, 2002 for the named executive officers are
provided in the second table on page 20 of this proxy statement. Additional
grants were made on February 11, 2003 to Mr. Cecil to purchase 12,745 shares,
and to Mr. Strathman to purchase 14,518 shares, each at the price of $27.07. The
number of performance shares outstanding at February 28, 2003 for the named
executive officers were: Mr. Williamson, 61,212; Mr. Ling, 43,224; Mr. Dallas,
34,500; Mr. Codon, 14,800; Mr. Strathman, 14,263; and Mr. Cecil, 13,370. The
maximum amounts payable to the named executive officers for outstanding
Performance Bonus Awards at February 28, 2003 were: $6.1 million for Mr.
Williamson, $6.1 million for Mr. Ling, and $3.05 million for Mr. Codon. No
Performance Bonus Awards were made to Messrs. Dallas, Strathman and Cecil.

     In 2000, the Boards of Directors of the Company and its Union Oil Company
of California subsidiary approved an enhanced severance program for U.S. payroll
employees not represented by collective bargaining agents in the event they lose
their jobs through a change of control of the Company occurring before 2005. In
the event of such a "change of control", as defined in the Company's Long-term
Incentive Plan of 1998, the program provides for the immediate vesting of
accrued benefits and/or accounts of all covered employees under the Company's
retirement and savings plans and the immediate payment to such employees in cash
of bonuses under its annual incentive compensation plans.

     The program also provides the following in the event of an eligible
employee's involuntary termination (other than for death, disability or
misconduct) or "constructive discharge" within two years following a change of
control:

     Employees with less than five years of service would receive four months of
base pay plus three-fourths of a month of base pay for every year of service.

     Employees with five or more years of service would receive four months of
base pay plus an enhanced retirement benefit. The enhanced benefit would add
three years to the employee's service and age, plus the benefit would utilize
the highest consecutive 12 months of pensionable pay in the most

                                       24



recent 120 months of service. The employee would also receive the incremental
difference in value, if any, of three-fourths of a month of base pay for each
completed year of actual service, to a maximum of 20 months, above the
discounted present value of the enhancement to the retirement benefit.

     Although all current executive officers are entitled to the benefits
described in the two preceding paragraphs, payment of such benefits would reduce
the amounts payable to Messrs. Williamson and Dallas under their employment
agreements and to Mr. Ling under his change in control agreement.

         The program permits an eligible employee to elect an immediate
distribution or rollover of his or her total retirement plan benefits. The
program also provides for subsidized "COBRA" medical and dental coverage for 18
months, a "three plus three" enhancement to criteria for determining eligibility
and contributions under the Company's retiree and special continuation medical
coverages and eligibility under its retiree life and AD&D insurance plans, as
well as certain other benefits.

     The program includes a "tax gross-up" arrangement for employees subject to
the excise tax provided for by Section 280G of the Internal Revenue Code,
including the named executive officers. Under this section, excise taxes are
imposed on employees receiving change-of-control payments (as defined) that
exceed 2.99 times the employee's average annual compensation (as defined). Under
the arrangement, an employee who is subject to the excise tax would receive a
gross-up payment, in addition to the amounts deemed change-of-control payments,
to eliminate the effect of the excise tax. This gross-up arrangement would apply
only if the employee's change-of-control payments exceed the excise tax
threshold amount of Section 280G by more than 10 percent. Otherwise, such
payments would be reduced below the threshold.


                           INDEBTEDNESS OF MANAGEMENT

         The Company made loans in 2000 to ten employees, three of which were
executive officers during 2002, for the purchase of Unocal common stock under
the 2000 Executive Stock Purchase Program, approved by stockholders at the 2000
Annual Meeting. The loans were made on March 16, 2000, and they mature on March
16, 2008. The loans accrue interest at 6.8%, compounded annually. The minimum
interest payable each March 16 during the years 2001 through 2005 is limited to
the amount of dividends paid during the prior 12 month period on the number of
shares purchased with the loan. Any remaining unpaid accrued interest is added
to the principal and accrues interest thereafter. Starting March 16, 2006,
principal is payable in three equal annual payments along with the full amount
of interest accrued over the past 12 months. The loans are full-recourse, with
exceptions for death or disability, and are not secured by the shares of common
stock purchased or by any other collateral.

         The loan agreements and related promissory notes were filed as exhibits
to the Company's Current Report on Form 8-K dated March 16, 2000.

                                     ITEM 2.
                         RATIFICATION OF APPOINTMENT OF
              PRICEWATERHOUSECOOPERS LLP AS INDEPENDENT ACCOUNTANTS

     The stockholders will be asked to ratify the appointment of the firm of
PricewaterhouseCoopers LLP as independent accountants for 2003. This appointment
was made by the Audit Committee of the Board of Directors.

     PricewaterhouseCoopers LLP, one of the nation's largest public accounting
firms, or one of its predecessors has served as the Company's independent
accountants for the past 58 years. Representatives of the firm are expected to
be present at the Annual Meeting and will have the opportunity to make a
statement if so desired and will be available to respond to questions.

                          REPORT OF THE AUDIT COMMITTEE

         The Audit Committee reviews the Company's financial reporting process
on behalf of the Board of Directors. The Committee is composed of four
independent directors, each of whom meets the independence standard of the New
York Stock Exchange. The Committee operates under a written charter recommended
by the Committee and adopted by the Board of Directors. The Charter is attached
to this proxy statement as Exhibit C. Management has the primary responsibility
for the financial statements and the reporting process. The Company's
independent accountants, PricewaterhouseCoopers LLP (PwC), are responsible for
expressing an opinion on the conformity of the Company's audited financial
statements to accounting principles generally accepted in the United States of
America.

     In this context, the Committee reviewed and discussed with management and
the independent accountants the audited financial statements to be included in
the Company's Annual Report on Form 10-K for the year ended December 31, 2002.
The Committee discussed with the independent accountants the matters required to
be discussed by Statement on Auditing Standards No. 61, "Communication with
Audit Committees," as amended. In addition, the Committee received from the
independent accountants the written disclosures required by Independence
Standards Board Standard No. 1, "Independence Discussions with Audit
Committees," and discussed with them their independence from the Company and its
management.

     In reliance on the reviews and discussions referred to above, the Committee
recommended to the Board of Directors that the audited financial statements be
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2002, for filing with the Securities and Exchange Commission.

                                             Audit Committee
                                             of the Board of Directors

                                             James W. Crownover, Chair
                                             John W. Amerman
                                             John W. Creighton, Jr.
                                             Ferrell P. McClean

     The preceding Report of the Audit Committee shall not be deemed
incorporated by reference into any filing under the Securities Act of 1933 or
the Securities Exchange Act of 1934, notwithstanding any general incorporation
by reference of this proxy statement into any other document or its inclusion as
an exhibit thereto.

                                       27





AUDIT FEES

     The aggregate fees for professional services rendered by PwC for the audit
of the Company's consolidated financial statements included in its Annual Report
on Form 10-K for the year ended December 31, 2002, and reviews of the Company's
financial statements included in its Quarterly Reports on Form 10-Q during 2002
were $3.6 million.

ALL OTHER FEES

     The aggregate fees for services rendered by PwC during 2002, other than
those set forth above, were $3.6 million. These services included:

     o    Compliance audits                     $0.4 million
     o    Benefit plan audits                   $0.1 million
     o    Tax services                          $2.7 million
     o    Information technology consulting     $0.3 million
     o    Internal control consulting           $0.1 million

     The Audit Committee has considered whether the rendering of non-audit
services to the Company by the independent accountants is compatible with the
accountants' independence. For the year 2002, PwC non-audit projects that
involved fees of $100,000 or more were reviewed by the Audit Committee. PwC
non-audit projects are defined as any work performed by PwC that is not required
for it to render its audit opinion on the Company's annual consolidated
financial statements. Effective May 2003, in accordance with rules of the
Securities and Exchange Commission implementing the Sarbanes-Oxley Act of 2002,
the Audit Committee will pre-approve all audit and allowable non-audit services
performed by PwC.

     The Board of Directors unanimously recommends a vote FOR ratification of
the appointment of PricewaterhouseCoopers LLP as independent accountants for
2003. The proxy holders will vote all proxies received FOR ratification unless
instructed otherwise.

     The affirmative vote of the holders of a majority of the shares present in
person or by proxy at the Meeting, and entitled to vote on this item, is
required for ratification of the appointment.


                                     ITEM 3
                              STOCKHOLDER PROPOSAL

     A stockholder has given notice that the following proposal will be
presented at the Meeting:

         "RESOLVED: The shareholders of Unocal Corporation (the "Company") urge
the Board of Directors to take the necessary steps to amend the bylaws to
require that an independent director who has not served as chief executive
officer ("CEO") of the Company shall serve as chairman of the Board of
Directors.

"Supporting Statement
---------------------

         "The primary purpose of the Board of Directors is to protect
shareholders' interests by providing independent oversight of management,
including the CEO. We believe that separating the roles of chairman and CEO will
promote greater management accountability to shareholders and lead to a more
objective evaluation of the CEO. In our opinion, an independent chairman will
enhance investor confidence in our Company and strengthen the integrity of the
Board of Directors.

                                       28



         "Recent corporate scandals have focused attention on the issue of board
independence and the need for an independent board chairman. According to the
Wall Street Journal, "in a post-Enron world of tougher corporate-governance
standards, the notion of a separate outside chairman is gaining boardroom
support as a way to improve monitoring of management and relieve overworked
CEOs" (Splitting Posts of Chairman, CEO Catches on With Boards, November 11,
2002).

         "Corporate governance experts have questioned how one person serving as
both chairman and CEO can effectively monitor and evaluate his or her own
performance. A blue-ribbon commission of the National Association of Corporate
Directors recently observed "it is difficult for us to see how an active CEO,
already responsible for the operations of the corporation, can give the time
necessary to accept primary responsibility for the operations of the board."

         "New listing standards proposed by the New York Stock Exchange also
stress the importance of independent boards. The proposed rules require that
non-management directors must regularly meet without management. An independent
chairman would provide strong leadership at these meetings.

         "Many institutional investors have found that a strong, objective board
leader can best provide the necessary oversight of management. For example, the
California Public Employees' Retirement System's (CalPERS) Corporate Governance
Core Principles and Guidelines advocate that a lead independent director be
appointed to coordinate the activities of the independent directors when the
offices of chairman and CEO are held by the same person. CalPERS also asserts
"true board independence may ultimately--within the next decade--require a
serious re-examination of this historic combination of [the chairman and CEO]
powers." (emphasis in original)

         "By setting agendas, priorities and procedures, the position of
chairman is critical in shaping the work of the Board of Directors. Accordingly,
we believe that having an independent director serve as chairman can help ensure
the objective functioning of an effective board. Conversely, we fear that
combining the positions of chairman and CEO may result in a passive and
uninvolved board that rubber-stamps the CEO's own decisions.

         "For these reasons, we urge a vote FOR this resolution."

                            DIRECTORS' RECOMMENDATION

     The Board of Directors unanimously recommends a vote AGAINST the adoption
of this proposal for the following reasons:

         The Board's current structure already provides for strong and
independent oversight of the Company's affairs and its management. An absolute
requirement to separate the positions of Chairman and CEO is not in the best
interest of the Company or its stockholders. Such a requirement would restrict
the flexibility the Board now has to provide the Company with the most effective
leadership at any given time. While in 2001 the Board separated the roles of the
Chairman and CEO, the Board believes that under current circumstances a
structure that includes a Chairman also serving as CEO and an independent Vice
Chairman is in the best interest of the Company and its stockholders.

     The Company has a strong system of governance that already provides for the
advantages sought by the proponent. The Company's corporate governance
principles (see Exhibit A, attached to this proxy statement ) include the
following:

     o    Evaluation of the CEO's performance:  a committee composed entirely of
          independent  directors,  the Management  Development and  Compensation
          Committee,  annually  evaluates the  performance of the CEO and senior
          management.

                                       29



     o    Board independence: eight of ten directors are independent.

     o    Board committee  independence:  the Board  Governance  Committee,  the
          Audit Committee, the Management Development and Compensation Committee
          and  the   Corporate   Responsibility   Committee   are  all  composed
          exclusively of independent  directors.  The Management Development and
          Compensation   Committee  has  sole  authority  to  hire  compensation
          advisors to advise on senior management compensation review. The Audit
          Committee  has the sole  authority to hire the outside  auditors.  The
          Board Governance Committee has the sole authority to hire search firms
          to identify director candidates and compensation advisors to advise on
          directors' compensation.

     o    Private meetings of independent directors:  Independent directors meet
          privately,  outside the  presence of the CEO, on a regular  basis;  in
          fact, a private session for independent directors is scheduled at each
          regular meeting of the Board.

     o    Independent directors' leadership: the Vice Chairman of the Board, who
          is an independent director, chairs the private meetings of independent
          directors. The Vice Chairman also sets the Board agenda in conjunction
          with the CEO.

     Unocal Directors' Code of Conduct (see Exhibit B, attached to this proxy
statement) strengthens the Board's independence by requiring that directors
inform the Chairmen of the Board and the Board Governance Committee of events,
circumstances or conditions that may impact the Board's assessment of whether
they meet the independence requirements of the New York Stock Exchange and the
Securities and Exchange Commission. This includes notification of any changes in
a director's employment, other board positions, and relationships with other
business, charitable and governmental entities.

Our Position:

         The Board believes that Unocal's corporate governance structure, with
its emphasis on independence and accountability, makes this stockholder proposal
unnecessary. Moreover, an absolute requirement that the Chairman be a
non-executive of the Company would unduly limit governance options now available
to the Board.

         The Board of Directors unanimously recommends voting AGAINST the
adoption of this proposal. The proxy holders will vote all proxies received
AGAINST this proposal unless instructed otherwise.

     The affirmative vote of the holders of a majority of the shares present in
person or by proxy at the Annual Meeting, and entitled to vote on this Item, is
required for approval of this proposal.

                                     ITEM 4
                              STOCKHOLDER PROPOSAL

A stockholder has given notice that the following proposal will be presented at
the Meeting:

         "RESOLVED: That the shareholders of Unocal Corporation, assembled at
the annual meeting in person and by proxy, hereby request the Board of Directors
to take the needed steps to hire an investment banking firm to sell the
Corporation.

"Supporting Statement
---------------------

         "This proposal is necessary due to the Company's chronic inability to
increase the value of the common stock. Taking into account the common stock's
miserable long term past performance, I believe it is in the best interest of
the Corporation and its stockholders that the Corporation be promptly sold with
the objective of realizing a premium over the current market price of its common
stock."

                            DIRECTORS' RECOMMENDATION

     The Board of Directors unanimously recommends a vote AGAINST the adoption
of this proposal for the following reasons:

     The Board unanimously believes that implementation of this proposal would
not be in the best interest of the stockholders or Unocal. The proponent, a
former employee, wrongly assumes that hiring an investment banker to sell Unocal
would increase stockholder value. The Board believes that carrying out this
proposal would not only fail to maximize stockholder value but would also harm
Unocal and its stockholders.

     Although approval of this proposal would not be binding, the Board believes
that its approval would erode stockholder value. Speculation that Unocal was
"for sale" would harm relationships with employees, business partners, foreign
governments and national oil and gas companies, thereby negatively impacting
Unocal's existing operations and its ability to obtain rights to new oil and gas
interests. This adverse impact could significantly compromise our future
opportunities and profits. The result: a decline in stockholder value.

         The Board is committed to increase the value of Unocal for all
stockholders, and will continue to pursue the strategies that it believes will
best achieve that objective. Unocal has assembled a very attractive portfolio of
properties and interests in some of the most desirable oil and gas basins
throughout the world. We expect to realize the significant value of this
portfolio over the next several years.

         The Board also has a fiduciary duty to make decisions in a manner that
it believes in good faith, after proper investigation, to be in the best
interest of Unocal and its stockholders, including any sale or other strategic
transaction involving Unocal. In this regard, the Board does not believe that a
forced sale of the Company, as is advocated by the proposal, is the way to
achieve maximum value for the stockholders.

         The Board has never foreclosed the possibility of any strategic
transaction that is in the best interest of Unocal and its stockholders. It
regularly reviews its strategic focus and alternatives, and considers
initiatives that may be implemented to maximize value for its stockholders. In
addition, Unocal has relationships with nationally recognized investment banking
firms and receives their advice on financial and strategic matters from time to
time.

Our Position

         Unocal is fully committed to enhancing stockholder value and continuing
to undertake initiatives to achieve that objective. The hiring of an investment
banker to engage in a forced sale of the company is counterproductive.

                                       31


         The Board of Directors unanimously recommends voting AGAINST the
adoption of this proposal. The proxy holders will vote all proxies received
AGAINST this proposal unless instructed otherwise.

     The affirmative vote of the holders of a majority of the shares present in
person or by proxy at the Annual Meeting, and entitled to vote on this Item, is
required for approval of this proposal.

     The Company will provide stockholders with the names and addresses of the
proponents of the stockholder proposals and information about their ownership of
Unocal common stock promptly upon receipt of an oral or written request to the
Secretary of the Company.


                                     ITEM 5.
                                 OTHER BUSINESS

Company's stock in compliance with the provisions of Section 7 of Article III of
the Company's Bylaws.

     The Board of Directors has no knowledge at the time of the printing of this
proxy statement of other business to be presented for action at the Annual
Meeting of Stockholders or any adjournment thereof. If other business properly
comes up for action at the Meeting, the proxy holders will vote the proxies in
their discretion.

                               UNOCAL CORPORATION
                         CORPORATE GOVERNANCE PRINCIPLES

Unocal's system of corporate governance emphasizes the Board of Directors'
independence and strengthens its ability to evaluate corporate and management
performance. It includes the following key principles:

     o    Eight of ten directors are non-management. All eight are independent.

     o    The Board  Governance  Committee,  composed of  independent  directors
          only, is charged with the  responsibility of advising the Board on all
          board  governance  matters,  including  recommending  the composition,
          role,  structure  and  procedures  of  the  board;   recommending  the
          appointment, composition and responsibilities of the committees of the
          board;  and  identifying  and  presenting   qualified  candidates  for
          election and re-election as directors.

     o    The Audit Committee, the Corporate  Responsibility  Committee, and the
          Management   Development  and  Compensation   Committee  also  consist
          entirely of independent directors.

     o    The  Management   Development  and  Compensation   Committee  annually
          evaluates the performance of the CEO and senior management.

     o    The board reviews  succession  planning and management  development at
          least annually.

     o    Compensation   for  executive   officers  is  linked  to  share  price
          performance,   operating  objectives  and  other  factors,   including
          adherence to the company's code of conduct.

     o    The board, as a matter of policy, does not authorize the re-pricing of
          stock options.

     o    The schedule and length of board  meetings allow  sufficient  time for
          in-depth discussions, analysis and strategic planning.

     o    Independent  directors  meet  privately on a regular  basis.  The Vice
          Chairman of the Board presides at such meetings.

     o    The board meeting format is designed to encourage  interaction between
          directors and the company's management.

     o    The board and its  Committees  have ready access to management and the
          right  to  hire  their  own  legal  or  other  outside  advisors.  The
          Compensation  and  Management   Development  Committee  has  the  sole
          authority  to hire and  terminate  compensation  advisors  for  senior
          management  compensation  review.  The  Audit  Committee  has the sole
          authority  to hire and  terminate  the  outside  auditors.  The  Board
          Governance  Committee  has the sole  authority  to hire and  terminate
          search firms to identify director candidates and compensation advisors
          to advise on directors' compensation.

     o    An orientation program is provided to each new director.

     o    Directors'  compensation  is reviewed  annually and includes  cash and
          stock-based incentives.

     o    Directors  must retire from the board on the day of the Annual Meeting
          of Stockholders following their 72nd birthday.

     o    The company ensures the confidentiality of stockholder votes.

     o    The board reviews its performance periodically.

     o    The board sets the corporate governance principles and reviews them at
          least annually.

                           DIRECTORS' CODE OF CONDUCT



Purpose

Unocal Corporation's ("Unocal") commitment to ethical and lawful business
conduct is a fundamental shared value of our Board of Directors, management and
employees and critical to the company's success. Our standards for business
conduct provide that we will uphold ethical and legal standards vigorously as we

compromised by Unocal anywhere at any time. Consistent with these principles,
Unocal's Board has adopted this Code of Conduct as a guide to the high ethical
and legal standards expected of its members.

o    Provide leadership in advancing the company's Vision, Values and Guiding
     Principles.

     on which they serve, in accordance with their good faith business judgment
     and in the best interests of the company and its shareholders.

     Committee of changes in their employment, other board positions,
     relationships with other business, charitable and governmental entities,

     Board's assessment of whether they meet the independence requirements of
     the New York Stock Exchange and the Securities and Exchange Commission.

o    Not enter into, without the prior approval of the disinterested members of
     the Board, any transaction or relationship with Unocal in which they will
     have a financial or personal interest (either directly or indirectly, such
     as through a family member or other person or organization with which they
     are associated), or any transaction or situation which otherwise involves a
     conflict of interest.

o    Maintain the confidentiality of all material non-public information about
     Unocal, its business and affairs.

o    Abide by all applicable laws and regulations and Unocal's Insider Trading
     Compliance Program.

                               UNOCAL CORPORATION
                             AUDIT COMMITTEE CHARTER

This Audit Committee Charter describes the Committee's organization, role and
primary duties. The Charter will be maintained to be consistent with relevant
external rules and regulations and with the needs of the Board of Directors and
the Company. This document does not attempt to describe the practices to be used
in carrying out the charter since these will evolve over time.


ORGANIZATION

The Audit Committee (Committee) shall consist of at least three members who
shall be independent Directors. All members of the Committee shall have (or
obtain within a reasonable time frame) working familiarity with basic finance
and accounting practices and at least one member of the Committee shall be an
audit committee financial expert. The chairperson and members of the Committee
shall be appointed by the Board on the recommendation of the Governance
Committee and may be replaced by the Board.

The Committee shall meet as often as it deems necessary, but not less than once
per quarter. It will utilize executive sessions with the independent accountant,
the internal auditor, and management. The chairperson will set the agenda for
the Committee. The Committee shall have the authority to retain such outside
professional assistance as it deems appropriate and shall have unrestricted
access to all company personnel, facilities and records. The Company shall
provide the financial resources the Committee requires in fulfilling its
obligations. The Committee shall keep minutes of its meetings, report to the
Board periodically, and present to the Board an annual evaluation of the
Committee's performance. Two members shall constitute a quorum. The Committee
may delegate from time to time its duties to a subcommittee made up of one or
more Committee members. Actions and decisions of any subcommittee shall be
reported to the Committee.


ROLE

The independent accountant and General Auditor shall report directly to the
Committee. With assistance from management, the Committee shall be responsible
for the appointment, compensation, retention and oversight of the independent
accountant. It will ascertain the independent accountant's qualifications and
independence and monitor its performance.

The Committee shall provide assistance to the Board in monitoring: 1) the
integrity and reliability of the Company's financial reporting; 2) the Company's
compliance with legal and regulatory requirements; 3) the adequacy of the
Company's internal operating policies and controls; and 4) the quality and
performance of combined management, independent accountant, and the internal
audit function. It is the responsibility of the Committee to maintain free and
open means of communication between directors, independent accountant, internal
auditors, and management.

While the Committee will pursue the purposes set forth in this Charter, it is
not the duty of the Committee to plan or conduct audits or to determine that the
Company's financial statements and disclosures are complete and accurate and are
in accordance with generally accepted accounting principles and applicable rules
and regulations. These are the responsibilities of management and the
independent accountant.


DUTIES

The Committee shall have duties such as the following, in carrying out the role
described above. It will be at the discretion of the Committee to determine the
time dedicated to each duty as well as its focus and manner of approaching the
duty.

                    independence, and

               o    Asserting that, in their  judgment,  they are independent of
                    the Company.

     4.   Obtain and review  annually a report from the  independent  accountant
          with  respect  to  their  internal  quality  control  procedures,  any

          review or peer review of the firm or by any  inquiry or  investigation

          with any such issue.

     5.   Review with the independent  accountant any  disagreements it has with

          the Company and the independent  accountant (e.g.,  five-year rotation

          personnel who have had a past relationship with the Company).

          resources.

          quality of  accounting  principles  employed,  the  reasonableness  of
          significant

                                      C-2


          judgments  and the  clarity of the  financial  statement  disclosures.
          Recommend to the Board whether the audited financial statements should
          be included in the Company's SEC Form 10-K.

     3.   Discuss with  management and the  independent  accountant  significant
          financial  reporting issues, and judgments made in connection with the
          preparation  of the  Company's  financial  statements,  including  any
          significant  changes in the  Company's  selection  or  application  of
          accounting  principles,  any major  issues as to the  adequacy  of the
          Company's  internal controls and any special steps adopted in light of
          material control deficiencies.

     4.   Review and discuss timely reports from the independent accountant on:

               o    Critical  accounting  policies and  practices to be used and

                    Committee by the  independent  accountants  under  generally
                    accepted auditing standards and/or SEC or NYSE regulations.

     5.   Discuss earnings press releases.

     6.   Discuss with management and the  independent  accountant the effect of

          policies and practices.

     8.   Review  disclosures made to the Committee by the Company's CEO and CFO

In general, the Committee shall review and investigate any matters pertaining to
the integrity of management, including conflicts of interest, the adherence to
business conduct as required in the policies of the company, and the adherence
to other legal and regulatory requirements. This shall include:

     1.   Regular reviews of compliance processes including legal and regulatory
          requirements  such as the Foreign Corrupt Practices Act and compliance
          training efforts.

     2.   Review of Company  policies and  procedures  for  reviewing  officers'
          expenses, perquisites and use of Company assets.

     3.   Meet with the Chief Legal  Officer and the other  Company  officers as
          necessary  including  review of any legal  matters  that  could have a
