Dear Stockholder:

  Please accept my invitation to attend our Annual Meeting of Stockholders on
Monday, May 22, 2000. 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.
The meeting agenda is to elect four directors, ratify the appointment of
independent accountants, approve the 2000 Executive Stock Purchase Program,
approve amendments to the 1998 Management Incentive Program, and vote on one
stockholder proposal. There will be a period for questions at the end.

  If you are a registered stockholder and plan to attend the Stockholders
Meeting, please mark the attendance box on your proxy card. 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. Please submit your proxy as soon as possible so that
your shares will be represented. This year, registered stockholders in the
U.S. and Canada and most "street name" holders may vote by proxy either by
mail, using the enclosed proxy card and return envelope, or by phone, using
the 800 number provided on the proxy card. Thank you very much for your
continued interest and support.

                                          Sincerely,

                                         Proxy Statement

[LOGO OF UNOCAL]

                                         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 Annual Meeting of
Stockholders of the Company to be held on May 22, 2000, and any adjournment
thereof, pursuant to the notice of the meeting.

  The notice of annual meeting and this proxy statement, proxy card and the
Company's 1999 Annual Report are being sent to stockholders on or about April
12, 2000.

  As of February 29, 2000, the Company had 242,616,186 shares of common stock
outstanding. Only common stockholders of record on the books of the Company at
the close of business on March 28, 2000 are entitled to vote at the meeting. A
stockholder of record is entitled to one vote for each share of common stock
owned. 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 appointment of
independent accountants), Item 3 (approval of the 2000 Executive Stock
Purchase Program), Item 4 (approval of amendments to the 1998 Management
Incentive Program) and Item 5 (stockholder proposal) will have the effect of
negative votes. The New York Stock Exchange has informed the Company that only
Item 3 (approval of the 2000 Executive Stock Purchase Program) and Item 5
(stockholder proposal) are "non-discretionary." Brokers who do not receive
instructions from their clients will not have discretion to vote on Item 3 or
Item 5, and these broker "non votes" will not be counted as votes cast for
determining their outcome.

                              GENERAL INFORMATION

  The 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 $16,000 plus reimbursement of out-of-pocket expenses. The
Board of Directors has appointed Messrs. Timothy H. Ling and Dennis P.R. Codon
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 envelope. Registered stockholders may instead
choose to vote at the meeting, or to vote by telephone, using the toll-free
number listed on the proxy card. 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 proxy card to determine whether you may vote by
telephone or electronically through the Internet, following the instructions
on the proxy card. "Street name" stockholders who wish to vote at the meeting
will need to obtain a proxy card from the institution that holds their shares.

                                       1
<PAGE>

  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 phone 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 Company's general voting policy is:

  Unocal's Board of Directors wishes to encourage stockholder participation
  in corporate governance by ensuring the confidentiality of stockholder
  votes. Therefore, the Company shall retain independent third parties to
  receive and tabulate stockholder votes. The manner in which any stockholder
  votes on any particular issue shall, subject to any 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
it.

                                    ITEM 1.
                             ELECTION OF DIRECTORS

  The Board of Directors consists of 10 directors divided into three classes.
Directors in each class are normally elected for three-year terms or until
their successors are duly elected and qualified. Four Directors have been
nominated for three-year terms expiring at the annual meeting in 2003. The
terms of the other six Directors will continue as indicated below.

  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.

  Information about the persons nominated for election as Directors, as well
as those Directors continuing in office, is set forth on the following pages.

  Directors are elected by a plurality of the votes of the shares entitled to
vote on the election and present, in person or by proxy, at the Annual
Meeting.

  The proxy holders will vote the proxies received by them FOR the four
nominees, unless authorization to vote for the election of any nominee has
been withheld.

DIRECTORS' COMPENSATION

Cash Compensation and Expenses

  The annual retainer for each non-employee Director is $25,000. Non-employee
Directors receive $3,000 for each one-day Board meeting attended, $1,000 for
each Board committee meeting attended, and an annual retainer fee of $6,000
for chairing a committee. All directors are reimbursed for actual out-of-
pocket expenses incurred in attending meetings and Company business. Directors
who are also employees of the Company receive no additional compensation for
services as Directors.

Stock Compensation

  The Directors' Restricted Stock Units Plan (the "Directors' Plan") for non-
employee Directors was approved by the Company's stockholders in 1991 for a
term of 10 years and authorizes the issuance of up to an aggregate of 300,000
shares of common stock. The Directors' Plan is administered by the Management
Committee. The Directors' Plan was amended such that, beginning with the
annual grant for 1996 and for elective deferred compensation after August 31,
1996, restricted stock units replaced restricted shares.

                                       7
<PAGE>

  Under the Directors' Plan each non-employee Director receives an annual
grant of restricted stock units equal in value to 20 percent of the Directors'
fees earned during the prior year.

  The Directors' Plan also allows each non-employee Director to make an annual
election to defer all or a portion of cash fees for the following year into
restricted stock units which may ultimately be paid out in shares of common
stock. This gives non-employee Directors an opportunity to increase their
stockholdings, which further aligns the interests of the non-employee
Directors with those of other stockholders. In consideration for forgoing the
current cash compensation, the value of the restricted stock units is equal to
120 percent of the fees deferred. Six of the seven outside directors elected
to defer some or all of their 1999 cash fees into restricted stock units.

  The restriction period for the restricted stock and restricted stock units
is generally five years, subject to the provisions of the Directors' Plan.
Each Director may elect to defer the receipt of his or her compensation for a
longer period of time. The restricted stock units accumulate in each
Director's account, and dividends are credited as additional restricted stock
units. At the end of the later of the restriction or deferral period for each
annual grant or annual elective deferral, shares of common stock are issued
equal to the number of accumulated restricted stock units.

  Restricted stock and restricted stock units cannot be sold, transferred, or
pledged, and are subject to forfeiture during the restricted period if the
Director is dismissed for cause, refuses to stand for reelection or resigns
for a reason other than Good Cause as defined in the Plan.

stock, and that any late filings be disclosed. The Company previously filed on
behalf of Directors separate reports of their acquisition of restricted stock
units under the Directors' Restricted Stock Units Plan and of their subsequent
acquisition of shares of common stock upon vesting of the units. Although
reports were timely filed of the acquisition of units by Charles R. Weaver,
who retired from the Board in May 1999, and by Dr. Whitman, one report for
each of them showing the acquisition of shares of common stock upon vesting of
the units was filed one month late in 1999.

                            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:

  .  Compensation Committee members are non-employees

  .  Salaries are based on comparisons with petroleum and energy industry
     averages

  .  Short-term and long-term incentives are linked to stock performance

  .  The peer group of companies was changed for 2000 to reflect the current
     business mix of the Company and changes in the petroleum industry

  .  Committee retains and is assisted by an outside consultant

  The Committee, composed entirely of 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 Management Incentive Program approved by the stockholders in
1998. 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 Chief Executive Officer ("CEO"). The
consultant and the CEO are present at Committee meetings but cannot vote. The
Committee meets outside the presence of the CEO on certain matters, including
CEO compensation and certain succession issues. The Committee met six times in
1999.

  The 1998 Management Incentive Program, consisting of the Revised Incentive
Compensation Plan, the Performance Stock Option Plan and the Long-Term
Incentive Plan of 1998, was developed to reinforce the goal of creating value
for the stockholders. The Program explicitly links short-term and long-term
incentive compensation to the Company's share price and its return to
stockholders (share price appreciation plus dividends) compared to that of a
group of companies in energy and 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. The companies comprising the Peer Group are
reviewed periodically and changed as the lines of business of these companies,
and of Unocal, change. Once the Peer Group is established for a particular
award, it is not altered. The Peer Group for 1999 Awards under the Management
Incentive Program consisted of 16 companies that as a group reflected Unocal's
lines of business following its exit from refining and marketing operations.
For 2000 Awards, three companies were added and four companies were deleted,
resulting in a Peer Group of 15 companies. These changes, in part, reflected
continuing restructuring in the petroleum industry.

  It is the Committee's belief and intention that applicable executive
compensation paid or accrued in 1999 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 the executive's
responsibilities. The Committee considers the responsibilities, experience and
performance of the executive officers and the survey data on the

                                      10
<PAGE>

compensation paid by energy and petroleum-related companies for similar
positions. In 1999, the Committee selected a group of 12 companies to use to
compare salary and other compensation ("Compensation Peer Group"). Eleven of
these companies are also part of the Peer Group used for comparative
stockholder returns. Following such a review in 1999, the salary of the CEO
was increased to $900,000. For 2000, the Compensation Peer Group was changed
to 11 companies, as a result of acquisitions in the industry and the changing
characteristics of the Company.

  The objective of the Committee is to establish base salaries that are near
the median paid by these surveyed companies in the Compensation Peer Group,
with adjustments for reporting relationships, responsibilities and job scope.
After increases to the base salary of the executive officers for 1999, 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.

Revised Incentive Compensation Plan

  The Revised Incentive Compensation Plan is the Company's annual bonus plan
for senior and middle management. Each award period under the Plan is one
year. Total cash awards under the Plan are determined in part by comparing the
Company's return to stockholders with the average return to stockholders
achieved by the Peer Group.

  The Committee establishes individual target awards for the CEO, the other
executive officers, and the other participants. The sum of these awards is the
target fund for the annual award period. Each target award is based on the
executive's position, responsibilities and the annual bonuses awarded by the
companies in the Compensation Peer Group.

  The actual fund available for awards is established by how the Company's
return to stockholders compares to that of the Peer Group. For 1999, the
Company's return to stockholders was at the 34.2% percentile of the composite
average of the Peer Group. Based on this return, the fund available for awards
was 42% of the target fund. In order to more closely align senior management
with the stockholders, the Committee decided to grant six of the Company's
nine executive officers, including Mr. Beach, restricted stock under the Long-
Term Incentive Plan in lieu of an annual bonus. Mr. Beach received 13,950
shares.

  A recipient could elect to receive up to 100 percent of the award in the
form of restricted stock. The restriction period varies between four and five
years, depending on the percentage of the award deferred. The award is
forfeited if the recipient resigns or is terminated for cause prior to the end
of the restriction period. The forfeiture provision does not apply to
participants retiring at or after age 65. Amounts deferred into restricted
stock for 1999 were augmented by up to 25 percent to compensate for the risk
of forgoing cash compensation. The Company's two executive officers receiving
an award elected to receive 100 percent of their 1999 awards as restricted
stock.

  The Committee has determined that to better align senior management with
stockholders, a minimum of 50% of any awards for calendar year 2000
performance will be paid in the form of restricted stock. This portion of the
awards will be increased by 50% to compensate for forgoing cash compensation.
Any additional amounts deterred into restricted stock will be increased by
25%. Other participants will continue to be able to defer awards on an
elective basis.

  The Committee reviewed the funding criteria for the Plan in 1999 and is
recommending changes that allow more flexibility in determining performance
measurements utilized for the year 2000. As noted in Item 4 beginning on page
25, the Company is recommending that the funding be based on "Net Cash
Provided by Operating Activities."

                                      11

Performance Stock Option Plan

  The Performance Stock Option Plan ("PSOP") was approved by the stockholders
in 1998 as part of the 1998 Management Incentive Program. The options under
the PSOP must have an exercise price at least 25% above the fair market price
at the date of grant. No person may acquire more than 750,000 shares of common
stock out of the total of 3,500,000 shares available under the PSOP.

  Initial awards of 3,000,000 shares under the PSOP were made in 1998,
including 750,000 to Mr. Beach, with an exercise price of $51.012 per share.
In order for the options to become exercisable after the three year
performance period ending March 30, 2001 either (i) the fair market value of
the shares must be greater than $51.012 for 10 consecutive trading days
(during a 20 consecutive trading day period) or (ii) the Company's Comparative
Return to Stockholders must be in the top quartile of the Peer Group for the
performance period. The term of the options is ten years. If neither condition
is met during the three-year performance period, the options are forfeited. As
of March 16, 2000 the performance conditions had not been satisfied and the
Company was near the mean of the Peer Group.

Long-Term Incentive Plan

  The Long-Term Incentive Plan of 1998 (the "1998 Plan") is administered by
the Committee. Awards may be in the form of non-qualified stock options,
performance shares and restricted stock. For each type of award, compensation
is linked to the performance of the Company's common stock and increases in
stockholder value. 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 1996, the Committee awarded a target number of performance share units to
the CEO and certain other of the executive officers for the 1996 through 1999
performance period under the 1991 Plan. Each unit is the equivalent of one
share of the Company's common stock. The target awards are dependent on the
executive's level of responsibility and base compensation. Mr. Beach's target
was 20,000 units.

  The actual payout of awards at the end of the four-year performance period
is determined by how the Company's return to stockholders for the period
compares to that of the Peer Group. The maximum percentage of the award that
can be paid out is 200 percent. During the 1996 to 1999 performance period,
the Company's average annual return to stockholders was slightly below that of
the Peer Group. Therefore, for that performance period, 91 percent of the
target number of performance shares was paid out to the participants,
including the CEO. These payouts were made one-half in cash and one-half in
shares of Company stock.

  Grants of non-qualified stock options were made to certain executive
officers. Under the terms of the PSOP, executives receiving performance stock
options are not eligible for other stock option grants in the years 1998, 1999
and 2000. Option grants are normally made in March. Prior option grants are
not considered in making these awards. 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 100,000 shares. The option exercise price
under the 1998 Plan is the fair market value on the date of grant. Exercise of
the 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.

  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. Since the total number of
shares available under the 1998 Plan and the PSOP is less than five percent of
the outstanding shares, individual grants

                                      12
<PAGE>

during the term of the 1998 Plan were not of such magnitude as to warrant
review of possible dilutive effects on the Company's stock.

  As described above, Unocal aligns management and stockholder interests by
linking executive incentive compensation programs directly to share price and
the creation of stockholder value. The Long-Term Incentive Plan of 1998 also
provides for grants of restricted stock to executives, managers and technical
employees whose performance and potential is exceptional. During the
restriction period, 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 real
contributions to the success of the Company and its stockholders, including an
Annual Incentive Plan, Chairman's Awards and Special Recognition Awards.

(A) Except for compensation reported for Mr. Beach for 1999, this column
    excludes perquisites because their value did not meet the reporting
    threshold of the lesser of $50,000 or 10 percent of salary plus bonus.

(B) Aggregate restricted stockholdings at year-end 1999 and value (based on
    closing market price on December 31, 1999): Mr. Beach 41,711 shares,
    $1,399,925; Mr. Imle 14,932 shares, $501,155; Mr. Ling 22,026 shares,
    $739,248; Mr. Williamson 6,381 shares, $214,162 and Mr. Scott 6,706
    shares, $225,070. Restricted stock granted on January 24, 2000: Mr. Beach
    13,950 shares; Mr. Ling 5,580 shares; Mr. Williamson 4,650 shares; and Mr.
    Scott 2,232 shares. The value of the restricted stock granted on January
    24, 2000 is shown in the "Bonus" column of this table. See footnote D.
    Dividends are paid on restricted stock.

(C) Represents payout of performance share units under the Long-Term Incentive
    Plan of 1991. The dollar values listed were paid one-half in cash and one-
    half in shares of Unocal common stock.

(D) Amount shown is the value of restricted stock awarded under the Long-Term
    Incentive Plan of 1998 in lieu of an annual bonus. The shares were valued
    for this disclosure using the closing price of Unocal common stock as
    reported on the New York Stock Exchange Composite Transactions Quotations
    on January 24, 2000, the date of grant.

(E) Includes $150,837 for relocation assistance and payment of taxes on the
    assistance.

(F) Amount consists of Company contributions of $9,600 allocated to the Unocal
    Savings Plan and $49,798 allocated to the Unocal Supplemental Savings
    Plan; and $1,890 reportable accumulated interest on deferred cash bonuses.

(G) Amounts consist of cash payments and deferred cash payments made under the
    Revised Incentive Compensation Plan. Amounts deferred into restricted
    stock under the Revised Incentive Compensation Plan appear in the
    "Restricted Stock Awards" column. See also Footnote H.

(H) Represents the value of a restricted stock award elected in lieu of all or
    a portion of a cash bonus payment under the Revised Incentive Compensation
    Plan. Amounts deferred into restricted stock for 1997 and 1998 were
    augmented by 20%, and the amount deferred into restricted stock for 1999
    was augmented by 25%, to compensate for the risk of forfeiture and to
    promote management stock ownership. The number of

                                        (Footnotes continued on following page)

    restricted shares was determined by using the average closing price of
    Unocal common stock during the last 30 trading days of the year. Valuation
    for purposes of this disclosure is based on the closing market price on
    the date of the award.

(I) Performance stock options granted at the option price of $51.012 in tandem
    with limited stock appreciation rights ("TLSARs"). Employees who received
    performance stock options did not receive grants of stock options in 1999
    and will not receive grants of stock options in 2000. The $51.012 exercise
    price of the options is a price 33 1/3% above the average fair market
    value of Unocal's common stock during the period from January 26, 1998 to
    May 29, 1998. The options become exercisable on March 30, 2001 only if
    either of the following vesting conditions is met: (a) the fair market
    value of the Company's common stock is equal to or greater than the option
    exercise price for ten trading days (occurring within any period of 20
    consecutive trading days) during the period March 30, 1998 through March
    30, 2001, or (b) the Comparative Return to Stockholders (as defined in the
    Performance Stock Option Plan) places the Company in the top quartile
    (75th percentile or above) of the peer group companies during the period
    March 30, 1998 through March 30, 2001, as determined by the Management
    Development and Compensation Committee. If neither of the vesting
    conditions is met, the options will not become exercisable. TLSARs were
    granted for a number of shares of common stock equal to .53 times the
    number of shares of common stock granted under the related performance
    stock option. The grant price for the TLSARs was $38.6875 (the fair market
    value of the common stock on the date of grant). The TLSARs become fully
    vested and payable only upon a "Conversion Date" following certain "Change
    in Control Events," as defined in the Performance Stock Option Plan. Each
    TLSAR will terminate on a ratable basis when the related performance stock
    option is exercised, terminated or forfeited.

(J) Amount consists of Company contributions of $9,600 allocated to the Unocal
    Savings Plan and $45,788 allocated to the Unocal Supplemental Savings
    Plan; and $2,586 reportable accumulated interest on deferred cash bonuses.

(K) Amount consists of Company contributions of $9,500 allocated to the Unocal
    Savings Plan and $38,300 allocated to the Unocal Supplemental Savings
    Plan; and $1,336 reportable accumulated interest on a deferred cash bonus.

    31, 1999. He will serve as a consulting employee of the Company through
    March 31, 2001.

    contributions of $9,600 allocated to the Unocal Savings Plan and $23,604
    allocated to the Unocal Supplemental Savings Plan; and $1,316 reportable
    accumulated interest on deferred cash bonuses.

(O) Amount consists of a disruption allowance of $85,000; Company
    contributions of $9,500 allocated to the Unocal Savings Plan and $19,656
    allocated to the Unocal Supplemental Savings Plan; and $523 reportable
    accumulated interest on a deferred cash bonus.

   by the Management Development and Compensation Committee as described in its
   Report beginning on page 10. The payout percentage will be determined by
   Unocal's relative ranking among the Peer Group and will range from 0% to a
   maximum of 200%. Under the formula, if the Company's percentage ranking is
   30% or less, the payout percentage will be 0%; if the Company's ranking is
   60%, the payout percentage will be 100%; and if the Company's ranking is
   100%, the payout percentage will be 200%. In the case of percentile rankings
   falling between more than 30% and less than 100%, payouts will be determined
   using straight-line interpolation. Awards are subject to downward adjustment
   by the Management Development and Compensation Committee. Return to
   stockholders is calculating using share price appreciation plus reinvested
   dividends. Awards paid out through 1999 have been paid out one-half in cash
   and one-half in shares of common stock.

(B) Mr. Imle's performance shares have been prorated for expected length of
    employment during the four-year performance period. His employment will
    terminate on March 31, 2001 pursuant to a Termination and Employment
    Agreement and Release, described further under the caption "Employment
    Contracts, Termination of Employment and Change of Control Arrangements" on
    page 19.

(A) Covered compensation is the annual average compensation in the three
    highest-paid years out of the last ten years preceding retirement. For the
    named executive officers in the Summary Compensation Table on page 15,
    covered compensation equals the amounts in the Salary and Bonus columns
    (except amounts shown as bonus for 1999) of the Summary Compensation Table
    and the amount of bonus that the participant elected to defer in restricted
    stock.

  The Company has a noncontributory defined benefit retirement plan covering
substantially all U.S. 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 a retirement supplement designed to maintain total
retirement benefits at the retirement plan formula level. This Pension Plan
Table, which covers all persons named in the Summary Compensation Table, shows
the estimated annual benefits from the these plans, before the deduction for a
portion of the estimated old age Social Security benefit, as described above.
The benefits shown are payable in the form of a straight life annuity.

  Covered compensation and credited full years of service under the retirement
plan as of year-end 1999 for the executive officers named in the Summary
Compensation Table are as follows: $1,422,377 and 38 years for Mr. Beach;
$761,368 and 33 years for Mr. Imle; $393,258 and 2 years for Mr. Ling; $416,780
and 22 years for Mr. Williamson; and $421,071 and 35 years for Mr. Scott.

EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND CHANGE OF CONTROL
ARRANGEMENTS

  The Company has employment agreements with Messrs. Beach, Williamson and
Scott. For Mr. Beach and Mr. Williamson, the agreements are effective for
three years from the later of July 28, 1998 and March 27, 2000, respectively,
or the date that 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. For Mr. Scott, the agreement
is effective for two years from the later of July 28, 1998, or the date that
the Company notifies him 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 his
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 (together, a
"Termination Without Cause"). For each of Messrs. Beach and Williamson, these
benefits include payments of 3.18 times his annual salary plus three times his
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 three years following the
Termination Without Cause. For Mr. Scott, these benefits include payments of
2.12 times his annual salary plus two times his 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. The
employment agreements with Mssrs. Beach and Williamson provide that if the
Terminaion Without Cause occurs within 36 months after a change of control,
the amounts payable under the agreements will be subject to a present value
reduction and a reduction to offset any compensation earned by them during the
three years immediately following the Termination Without Cause. Mr. Scott's
employment agreement provides that if the Termination Without Cause occurs
within 24 months after a change of control, the amounts payable under the
agreement will be subject to a present value reduction and a reduction to
offset any compensation earned by him during the two years immediately
following the Termination Without Cause. In each case, the employee is
entitled to an additional payment (a "Gross-Up Payment") if any payment under
the agreement would be subject to the excise tax imposed by Section 4999 of
the Internal Revenue Code (the "Excise Tax") such that the employee retains an
amount of the Gross-Up Payment equal to the Excise Tax imposed. 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 the employee,
such that the receipt of payments would not give rise to any Excise tax, then
no Gross-Up Payment will be made to the employee and the payments will be
reduced to the Reduced Amount. The agreements, together with the February 28,
2000 amendments thereto, for Messrs. Beach and Scott were filed with the
Securities and Exchange Commission as exhibits to the Company's Annual Report
on Form 10-K for the year ended December 31, 1999 (the "1999 Form 10-K"). The
agreement for Mr. Williamson was filed as an exhibit to the the Company's
Current Report on Form 8-K dated March 16, 2000.

  The Company had an employment agreement with Mr. Imle, who served as Vice
Chairman until December 31, 1999. The employment agreement was effective
starting July 28, 1998 with the same provisions as the agreement with Mr.
Beach described above prior to its amendment. The employment agreement with
Mr. Imle was filed as an exhibit to the Company's Quarterly Report on Form 10-
Q for the quarter ended June 30, 1998. Pursuant to a Termination and
Employment Agreement and Release, effective September 11, 1999, Mr. Imle
received a severance payment in the amount of $2,215,575 in full satisfaction
of all rights, benefits and payments under his employment agreement. The
Termination and Employment Agreement and Release was filed as an exhibit to
the Company's Quarterly Report on Form 10-Q for the quarter ended September
30, 1999. Mr. Imle will continue as a consulting employee through March 31,
2001 at a salary of $525,000 for 2000, and $65,625 for the three months in
2001.

                                      19

  The Company has a change in control agreement with Mr. Ling that is
effective for three years from the later of July 28, 1998 or for three years
following the day the Company gives notice that it does not wish to further
extend the term. The agreement was amended on February 28, 2000, to provide
that in the event of a Termination Without Cause within 36 months following a
Change of Control (as defined in the agreement) 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. Beach described above, except that
payments under Mr. Ling's agreement are not subject to reduction for
compensation earned by him during the three years immediately following his
Termination Without Cause. The agreement, together with the February 28, 2000
amendment thereto, was filed as an exhibit to the 1999 Form 10-K.

  The Management Development and Compensation Committee has authorized the
automatic accelerated vesting of restricted stock, the vesting of unvested
options, and the payment of performance shares to the named executive officers
in the Summary Compensation Table in the event of a change in control. Tandem
Limited Stock Appreciation Rights awarded to those executive officers in
combination with performance stock options become fully vested and payable on
a "Conversion Date" following certain "Change in Control Events" as defined in
the Performance Stock Option Plan. See footnote I to the "Summary Compensation
Table" on page 16 for more information regarding the stock appreciation
rights.

                          INDEBTEDNESS OF MANAGEMENT

  Pursuant to agreements dated March 16, 2000, the Company has made loans to
ten officers, including four executive officers, totaling $32 million for the
purchase of Unocal common stock under the 2000 Executive Stock Purchase
Program. Item 3 of this Proxy Statement, beginning on page 21, provides
details regarding the loans.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.

                        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 2000. This
appointment was made by the Board of Directors on the recommendation of its
Accounting and Auditing Committee.

  PricewaterhouseCoopers LLP, one of the nation's largest public accounting

accountants for the past 55 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.

  The affirmative vote 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.

  The Board of Directors unanimously recommends a vote FOR ratification of the
appointment of PricewaterhouseCoopers LLP as independent accountants for 2000.
The proxy holders will vote all proxies received FOR ratification unless
instructed otherwise.

                                    ITEM 3.
               APPROVAL OF 2000 EXECUTIVE STOCK PURCHASE PROGRAM

  The Board of Directors, with Messrs. Beach, Ling and Williamson abstaining,
upon the recommendation of the Management Development and Compensation
Committee (the "Committee"), has adopted a new 2000 Executive Stock Purchase
Program (the "Stock Purchase Program") in order to attract and retain senior
executives and other key employees of the Company and its subsidiaries, and is
submitting the Stock Purchase Program for stockholder approval. The Stock
Purchase Program is administered by the Committee, which is comprised entirely
of non-employee directors.

  This proposal requests, and the Board of Directors recommends, stockholder
approval of the Stock Purchase Program. If this proposal is not approved by
the stockholders, the Company will discontinue the Stock Purchase Program (see
page 23) and will continue to make other awards under the Management Incentive
Program, and consider other compensation arrangements in order to retain its
senior executives and other key employees.

                                      21
<PAGE>

  The following summary of the material terms of the Stock Purchase Program is
qualified in its entirety by reference to the full text of the Stock Purchase
Program, which is attached to this proxy statement as Exhibit A.

Background

  The Stock Purchase Program provides that the Company may loan to senior
management selected by the Committee funds to purchase shares of the Company's
common stock. In the discretion of the Committee, such purchases may be either
open market purchases or purchases directly from the Company. Each loan (a
"Loan" or "Loans") will be for 100% of the purchase price, including
commissions, if any, will be full-recourse and will be interest-bearing.
Participants who purchase common stock also will be eligible to receive
Performance Bonus Awards under the Long-Term Incentive Plan of 1998 (which is
part of the Management Incentive Program, as amended) which will be paid out
in cash upon satisfaction of certain performance and other criteria. Details
of Performance Bonus Awards are explained in Item 4 (page 28) and in Exhibit B
of this proxy statement.

Purpose of the Stock Purchase Program

  The Stock Purchase Program incorporates an important element of investment
risk that generally is not found in other executive incentive plans because
participants in the Stock Purchase Program share in both the upside and
downside potential inherent in stock ownership by purchasing a substantial
amount of common stock of the Company using full-recourse loans. The Program
is thus designed to promote the long-term growth and financial success of the
Company by strengthening the financial links between the Company's senior
management and stockholders.

Awards

  Participants selected by the Committee are afforded the opportunity to have
the Company loan them amounts which are to be utilized to purchase shares of
common stock of the Company ("Awards") on a specified date or dates (the
"Purchase Date") either, in the discretion of the Committee, in the open
market or directly from the Company. The purchase price of shares acquired
from the Company will be the average of the high and low sales prices for the
common stock as reported on the New York Stock Exchange Composite Transactions
on the Purchase Date if from the Company, or the actual purchase price if on
the open market. The maximum number of shares which may be purchased under the
Stock Purchase Program is 1,750,000 and the maximum number of shares which may
be purchased by any participant is 200,000, subject to proportionate
adjustment in the event of a stock split, stock dividend, or other change in
capitalization.

Company Loans

  Each Loan that is part of an Award is for the entire purchase price of the
common stock, including commissions, if any, is full recourse and is interest-
bearing. A full-recourse loan requires the borrower to be personally liable
for the full amount of the loan, regardless of the ultimate value of the
shares purchased with the proceeds of the loan. Principal on the Loans is not
payable until the fifth anniversary of the Purchase Date. After five years,
there will be three equal annual payments of principal plus accrued and unpaid
interest. The Loans will accrue interest at the "applicable federal rate" (as
determined by Section 1274(d) of the Internal Revenue Code) on the Purchase
Date for loans of such maturity, compounded quarterly. Until the fifth
anniversary of the Purchase Date, interest on the Loans is payable only in an
amount equal to any cash dividends paid on the shares of common stock
purchased pursuant to an Award. Any interest unpaid is added to the principal
and becomes payable commencing on the sixth anniversary of the Purchase Date.
The Loans will not be secured by the shares of common stock purchased or any
other collateral.

                                      22
<PAGE>

  In the event a participant terminates his or her employment with the Company
voluntarily (including through early retirement) or is terminated by the
Company for cause, the Loan must be repaid within 60 days of the termination.
In the event a participant dies or is disabled, the Loan will continue to
maturity and if the outstanding balance on the Loan, increased by the amount
of any prior payments of principal on the Loan, is greater than the sum of (1)
the then fair market value of the shares of common stock purchased plus (2)
the amount of the Performance Bonus Award payout (see page 28) for the
performance period ending on December 31, 2003, plus (3) an amount equal to
the amount of interest that would have accrued on such payout had it been
invested and earned the same rate of interest as that accrued on the Loan from
December 31, 2003 until the applicable date of repayment, then the Company
will forgive the Loan to the extent of such excess.

                2000 EXECUTIVE STOCK PURCHASE PROGRAM BENEFITS

   As set forth in the following table, ten participants, including the Chief
Executive Officer and three other executive officers, received Loans on March
16, 2000, which were utilized to purchase 1,150,310 shares of common stock in
the open market during the period March 16 to 23, 2000, at an average cost,
including commissions, of $27.82. This leaves 599,690 shares of common stock
available for future Awards.

</TABLE>

  All Loans bear interest at the rate of 6.8 % per annum (the "applicable
federal rate" for March 16, 2000), mature on March 16, 2008, and have the
other terms described under "Company Loans" above.

  The Company and the participants have agreed that, if the Stock Purchase
Program is not approved by the stockholders, the shares listed above will be
sold to the Company for the lesser of the purchase price or their fair market
value at the time of the resale, and the Loans will become immediately due and
payable.

Accounting Aspects

  For financial accounting purposes, a charge to earnings will be made for any
excess of the market price on May 22, 2000 (assuming the Stock Purchase
Program is approved by the stockholders on that date) over the purchase price
of the shares. In addition, the accrued interest on the Loans (whether or not
payable at such time) will be credited to the Company's earnings each quarter.

General Provisions

  The Stock Purchase Program will terminate on December 31, 2003, provided
that Loans outstanding on that date will not be affected or impaired by such
termination.

                                      23
<PAGE>

  The Board of Directors may at any time amend, suspend or terminate the Stock
Purchase Program prior to December 31, 2003; provided that no amendment,
suspension or termination may, without the consent of the participant,
adversely affect a participant's rights in any material respect; and provided
further that, without stockholder approval, no amendment may (1) increase the
maximum number of shares of common stock which may be purchased, (2) permit a
purchase of shares for less than fair market value, or (3) extend the
termination date of the Stock Purchase Program.

Certain Federal Income Tax Consequences

  The following is a summary of the material tax consequences of the Stock
Purchase Program to the Company and to the participants, based upon the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations
thereunder, administrative rulings and court decisions as of the date of this
proxy statement.

 . Tax Consequences to Participants

  Participants who are subject to Section 16(b) of the Securities Exchange Act
of 1934 could be taxed at ordinary income rates on the excess of the fair
market value of the shares of common stock they purchase (the "Program
Shares") six months after the purchase date (when the Section 16(b)
restrictions lapse) over the amount paid for such Program Shares. However,
within 30 days after purchasing Program Shares, participants may make an
election under Section 83(b) of the Code to be taxed on the difference between
the fair market value of the Program Shares and the purchase price on the date
of purchase. If a participant makes such an election, no tax should be due on
the purchase because the purchase price is designed to equal the fair market
value of the Program Shares on the date of purchase. The following discussion
assumes that the affected participants will each make the election under
Section 83(b) of the Code.

  Any dividends or distributions on the Program Shares will be includable in
the participants' income to the extent made out of the Company's earnings and
profits, but such income will be offset by a corresponding payment on the Loan
to the extent of accrued interest. When the Program Shares are sold, the sale
will result in capital gain or loss measured by the difference between the
amount paid for the Program Shares when purchased by the participant and the
amount realized upon sale. Such capital gain or loss will be long-term if the
participant held the Program Shares for over a year. The participants will
generally be able to deduct the interest that accrues on the Loans subject to
the limitations described below.

  The interest on the Loans will be "investment interest" and therefore may be
deducted only to the extent of each participant's net investment income,
including investment income relating to other investments (i.e., the excess of
investment income, including dividends and income from the disposition of
property held for investment, over expenses directly connected with the
production of such income). Investment interest that is not deducted can be
carried forward indefinitely. When the Program Shares are sold, investment
interest that has been carried forward may be used to offset any gain realized
on such sale.

 . Tax Consequences to the Company

  Assuming that the participants make a timely election under Section 83(b) of
the Code, no deduction will be available to the Company upon the purchase of
Program Shares by participants. The Company will include in its gross income
the interest on the Loans.

  The Board of Directors unanimously recommends a vote FOR approval of the
2000 Executive Stock Purchase Program. The proxy holders will vote all proxies
received FOR approval unless instructed otherwise.

                                      24
<PAGE>

  The affirmative vote 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
approval of the Stock Purchase Program. In the event the stockholders do not
approve the Stock Purchase Program, all shares of common stock purchased
pursuant to the Stock Purchase Program will be sold to the Company for the
lesser of the original purchase price or the fair market price of the common
stock on the date of resale, and each Loan will become immediately due and
payable.

                                    ITEM 4.
                           APPROVAL OF AMENDMENTS TO
                       1998 MANAGEMENT INCENTIVE PROGRAM

  In 1998 the Board of Directors adopted and the stockholders approved the
Company's 1998 Management Incentive Program (the "Management Incentive
Program") in order to attract and retain individuals of the highest caliber as
employees of the Company and its subsidiaries. The Management Incentive
Program consists of the Revised Incentive Compensation Plan (the "RICP"),
which provides for annual cash bonus awards, a portion of which may be
deferred or paid as restricted stock; the Long-Term Incentive Plan of 1998
(the "LTIP"), which provides for grants of non-qualified stock options,
performance shares and restricted stock; and the 1998 Performance Stock Option
Plan (the "PSOP"), which provides for grants of non-qualified performance
stock options, which have an exercise price at a premium over the fair market
value of the shares of the Company's common stock on the date of grant, and
tandem limited stock appreciation rights. The Management Incentive Program is
administered by the Management Development and Compensation Committee (the
"Committee"), which is comprised entirely of non-employee directors.

  The Board of Directors, with Messrs. Beach, Ling and Williamson abstaining,
upon the recommendation of the Committee, has amended the Management Incentive
Program, subject to stockholder approval, (1) to change the funding method
used and add three additional performance criteria that may be used in
determining the amount of the incentive compensation paid under the RICP and
(2) to provide for Performance Bonus Awards under the LTIP.

  This proposal requests, and the Board of Directors recommends, stockholder
approval of the amendments to the Management Incentive Program. If the
amendments are not approved by the stockholders, the Company will continue to
make awards under the Management Incentive Program as presently constituted
and consider other compensation arrangements in order to retain its senior
executives and other key employees.

  The following summary of the material terms of the Management Incentive
Program and of the amendments to the Management Incentive Program is qualified
in its entirety by reference to the full text of the Management Incentive
Program, as amended, which is attached to this proxy statement as Exhibit B.

Eligibility

  The Committee, in its discretion, may select as Management Incentive Program
participants any employees of the Company and its subsidiaries, except that
only senior management and other key employees may be selected to participate
in the PSOP.

  While the LTIP does not limit the employees of the Company who may be
granted the Performance Bonus Awards which are provided for in the amendments,
it is currently the intention of the Committee to grant such awards only to
senior executives of the Company who are participating in the Stock Purchase
Program, with the maximum amount of the awards shown on the table on page 29.

                                      25

Awards Under the Revised Incentive Compensation Plan

  The RICP provides for awards and payments to be determined on a yearly basis
(the "RICP Award Period"). The Committee establishes individual target awards
for each participant. The sum of these awards is the target fund for the
annual RICP Award Period. Under the existing RICP, this fund is adjusted based
on the Company's "Comparative Return to Stockholders" over the RICP Award
Period, which means the Company's return to stockholders compared to the
return to stockholders of a group of comparable companies selected by the
Committee in its sole discretion. The fund is subject to further adjustment
for minimum Company performance requirements as determined by the Committee.
The adjusted fund is allocated in whole or in part to participants on the
basis of: (i) comparison of actual operational results to plans or goals,
adjusted for external factors such as changes in market prices; (ii)
individual performance of employees selected to participate in the Plan; and
(iii) reasonableness of total cash compensation. The maximum cash award to a
participant for an Award Period will be $2,000,000.

  Unless otherwise provided, payment of awards are made in cash from the
general funds of the Company in a manner (which may include deferral of cash
awards) prescribed by the Committee. Payment of an award may be made all or in
part as restricted stock as determined by the Committee or pursuant to an
election by the recipient under such terms as the Committee may establish. In
consideration for forgoing cash compensation, the Committee may grant
restricted stock with a total dollar value greater than the cash amount
deferred, provided that any such increase does not exceed 100% of the dollar
value of the cash amount deferred. The number of shares of restricted stock so
issued is based on the fair market value of the Company's common stock, after
any such increase described above.

  If an employee elects to defer a cash payment into restricted stock, such
restricted stock must have a restriction period of not less than four years.
Employees are entitled to vote the restricted stock and receive dividends
during the restriction period. If the employee has satisfied all of the
conditions on the restricted stock established by the Committee by the end of
the restriction period, the Company will remove any restrictions on the shares
and deliver any accumulated unpaid dividends, less any amounts withheld for
taxes.

 Delegation of Authority

  The Committee may, in its discretion, delegate the authority to grant awards
under the RICP for employees other than executive officers to a committee of
the Board of Directors of the Company.

Amendment to Change Method of Determining Bonus Pool and Performance Criteria
under the Revised Incentive Compensation Plan

  Under the existing RICP, the Committee establishes an individual target
award for each participant ("Award"). The sum of these individual target
awards is the target fund for the year. This target fund is then adjusted
based on the Company's Comparative Return to Stockholders for the year, as
described above. The amendment to the RICP provides, subject to stockholder
approval, that the bonus pool for a year will be equal to 2% of the Company's
"Net Cash Provided by Operating Activities" (as defined in the RICP) during
that year. The aggregate amount of Awards, without giving effect to any
augmentation upon deferral into restricted stock, under the RICP for a year
may not exceed this bonus pool.

  The amendment also provides that, for the Chief Executive Officer and
certain other executive officers, the Committee will establish Awards, each of
which will be for a percentage of this bonus pool. The Committee will have the
sole discretion to determine whether the full amount of such an Award will be
paid and may reduce, but may not increase, the amount of the Award payable
based on any criteria that the Committee determines. The criteria may include,
but are not limited to, one or more of the following: (i) individual
performance, (ii) the Company's "Comparative Return to Stockholders," (iii)
the Company's "Return on Capital Employed" and (iv) the Company's "Future Year
Value Creation" (all as defined in the RICP).

                                      26
<PAGE>

  The amendment further provides that the Committee will establish individual
target Awards for the remaining participants based on such criteria as the
Committee shall determine, which criteria may include, but are not limited to,
one or more of the following: (i) salary grade, (ii) the Company's
"Comparative Return to Stockholders," (iii) the Company's "Return on Capital
Employed" and (iv) the Company's "Future Year Value Creation" (all as defined
in the RICP). Subject to the amount of the bonus pool available after payment
of the Awards described in the immediately preceding paragraph, the Committee
may increase or decrease the amounts payable to participants under the Awards
described in this paragraph on the basis of factors such as, but not limited
to, the following: (i) comparison of actual operational or financial results
to plans or goals, adjusted for external factors such as changes in market
prices, (ii) individual performance of employees selected to participate in
the RICP and (iii) reasonableness of total cash compensation.

  Finally, the amendment provides that the maximum cash Award to a participant
for a year will be 0.25% of the Company's Net Cash Provided by Operating
Activities or, if less, $2,000,000. The portion of an Award deferred in the
form of restricted stock may still be increased up to 100%.

Awards under the Long-Term Incentive Plan

 Stock Options

  Non-qualified stock options may be granted by the Committee, which
determines the number of shares subject to each stock option and the manner,
conditions and time of exercise. The Committee may impose restrictions on
shares acquired through exercise. No options are exercisable more than 10
years after the date of grant. The option price per share may not be less than
the fair market value of a share of common stock on the date of grant, and is
payable in cash and/or shares of common stock as determined by the Committee.
Options are evidenced by stock option agreements in a form approved by the
Committee.

  Stock options are nontransferable except in the event of the employee's
death, unless the Committee, in its sole discretion, permits transfers to the
employee's family members and entities established for or owned by family
members. The granting of an option does not entitle the employee to the rights
of a stockholder; such rights accrue only after exercise and registration of
shares. No person may be granted during any 12-month period options to acquire
more than 100,000 shares of common stock under the LTIP.

 Performance Shares

  Performance shares may be granted by the Committee with respect to a period
of time of not less than four years (an "LTIP Award Period"). Each performance
share shall have a value equivalent to one share of common stock of the
Company. No participant may receive more than 30% of the aggregate number of
performance shares granted or more than 25,000 performance shares in a 12-
month period.

  At the end of an LTIP Award Period, the Committee establishes a percentage
by which the performance shares awarded shall be multiplied, based on the
Company's Comparative Return to Stockholders, and each holder's performance
shares shall be multiplied by that percentage. In no event shall such
percentage exceed 200%. Additionally, the value of the awards paid shall in no
event exceed more than 400% of the value of the award at the time of grant.
The payments are normally made in a combination of shares of the Company's
common stock and cash.

 Restricted Stock

  The Committee may grant shares of common stock which are subject to certain
restrictions. The restriction period shall be at least four years. The
employee is entitled to vote the restricted stock and receive dividends during
the restriction period. If the employee has satisfied all of the conditions of
the

                                      27
<PAGE>

restricted stock award established by the Committee by the end of the
restriction period, the Company will remove any restrictions on the shares and
deliver any accumulated unpaid dividends, less any shares withheld for taxes.

 Delegation of Authority

  The Committee may, in its discretion, delegate the authority to grant awards
under the LTIP for employees other than executive officers to a committee of
the Board of Directors of the Company.

Amendment to Provide Performance Bonus Awards under the Long-Term Incentive
Plan

  A new Section 10 has been added to the LTIP, subject to stockholder
approval, providing for grants of Performance Bonus Awards ("Bonus Awards")
payable in cash if and to the extent the goal or goals established by the
Committee are satisfied. At the time of granting a Bonus Award, the Committee
establishes (i) the goal or goals, based in part on the Company's "Comparative
Return to Stockholders" and changes to the price of the Company's common stock
and (ii) a matrix to be used to determine the cash amount, if any, that will
be paid based on the extent to which the goal or goals are achieved. In
determining the range of possible Bonus Award payments, the Committee may take
into account the amount of any Loan made in connection with the 2000 Executive
Stock Purchase Program, a participant's responsibility level, cash
compensation level, and the fair market value of the Company's common stock at
the time of the Bonus Award, as well as such other considerations as it deems
appropriate. Performance against established goals will be measured over an
LTIP Award Period of four years, subject to early termination as described
below. The maximum performance bonus that may be paid to any person for any
four-year LTIP Award Period is $6,500,000. The maximum performance bonus that
may be paid to any person for any LTIP Award Period that is longer than four
years is $1.625 million times the number of years in the LTIP Award Period.

  In the event of a "Change in Control" (as defined in the LTIP) of the
Company, the Committee will declare any Award Period ended as of the date of
the Change in Control and accelerate the payment of the Bonus Award; provided,
that in no event will the participant's Bonus Award payout be less than 50% of
the target amount under such circumstances. If a participant terminates
employment during an Award Period for any reason other than voluntary
termination or termination for cause, the Bonus Award will remain outstanding
and the participant will receive the same Bonus Award payout at the end of the
LTIP Award Period, based on the Company's Comparative Return to Stockholders,
as if the participant had remained employed during the full LTIP Award Period.
If a participant terminates employment during an Award Period voluntarily or
is terminated for cause, then the Bonus Award will be forfeited and no payout
will be made.

Awards under the Performance Stock Option Plan

 Performance Stock Options

  Non-qualified performance stock options may be granted by the Committee,
which determines the number of shares subject to each performance stock option
and the manner, conditions and time of exercise. No performance stock options
are exercisable more than 10 years after the date of grant. The option price
per share must be at a premium of at least 25% over the fair market value of a
share of common stock on the date of grant, as determined by the Committee,
and is payable in cash and/or shares of common stock acceptable to the
Committee. Performance stock options must satisfy performance and vesting
conditions established by the Committee in order to become subject to
exercise. If the performance and vesting conditions are satisfied, performance
stock options will normally remain outstanding following an employee's
termination of employment for the remaining term of the option. Performance
stock options are evidenced by grant agreements in a form approved by the
Committee.

                                      28
<PAGE>

  Performance stock options are nontransferable except in the event of the
employee's death, unless the Committee, in its sole discretion, permits
transfers to the employee's family members and entities established for or
owned by family members. The granting of an option does not entitle the
employee to the rights of a stockholder; such rights accrue only after
exercise and registration of shares. No person may be granted during any 36-
month period performance stock options to acquire more than 750,000 shares of
Common Stock under the PSOP.

 Tandem Limited Stock Appreciation Rights

  The Committee may grant tandem limited stock appreciation rights (TLSARs) in
combination with an underlying performance stock option. A TLSAR is a right to
receive a payment in cash, or in shares of common stock in certain events,
with respect to a specified number of shares of common stock, equal to the
excess of the fair market value of the common stock on the date the TLSAR
becomes payable over the grant price for the TLSAR established by the
Committee, which may not be less than the fair market value of the common
stock on the date the TLSAR was granted. A TLSAR will become payable only on a
Conversion Date after the occurrence of a Change in Control Event (as defined
in the PSOP) and generally expires upon expiration or exercise of the
underlying performance stock option. The performance and vesting conditions
for a performance stock option do not have to be satisfied in order for the
related TLSAR to become payable on a Conversion Date.

Awards Under the Management Incentive Program for 2000

  The table below summarizes the awards for 2000 made through March 28 under
the existing Management Incentive Program and, subject to stockholder
approval, the maximum Bonus Awards and the maximum cash awards that would be
awarded under the Management Incentive Program as amended. Non-routine awards
and awards to future employees may be made after March 28, but are not
presently determinable.

(A) The amounts shown are the maximum amounts payable based on projected "Net
    Cash Provided by Operating Activities" for the year 2000. One half of the
    payment to executive officers will be made in shares of restricted stock,
    increased by 50% of the dollar amount of the cash award deferred into
    stock; these shares will have a five-year restriction period. Executive
    officers may also elect to defer all or part of the remaining 50% of their
    cash payment into shares of restricted stock; if they so elect, the amount
    deferred into stock will be increased by 25% and the shares will have a
    four-year restriction period. Other recipients may elect to have all or
    part of their cash awards paid out in shares of restricted stock on the
    same basis. Restricted shares receive dividends during the restricted
    period.

(B) Represents the options granted on February 24, 2000 at an exercise price
    of $28.3438 under the LTIP. The options become exercisable in four equal
    installments on six months, twelve months, 24 months and 36 months from
    the date of grant.

(C) The closing market price as reported in the New York Stock Exchange
    Composite Transactions quotations on January 3, 2000, which was the
    commencement of the award period, was $33.00. The provisions governing
    these performance shares are the same as described in footnote (A) to the
    "Long-Term Incentive Plan Awards in 1999" table on page 17.

(D) Represents the maximum cash Performance Bonus Awards payable under the
    LTIP if the performance goals are fully satisfied. These Awards are
    subject to stockholder approval of the amendments to the Management
    Incentive Program.

(E) The shares have a minimum four-year restriction period. Recipients are
    entitled to vote the shares and receive dividends during the restriction
    period. The value shown is based on the closing market price as reported
    in the New York Stock Exchange Composite Transactions quotations on the
    dates of the grants.

(F) Mr. Imle served as Vice Chairman until his resignation, effective December
    31, 1999. He will serve as a consulting employee through March 31, 2001.

Federal Income Tax Consequences

  Under current law, cash awards will be taxed as ordinary income to the
employee in the year in which they are received. When the employee is taxed,
the Company receives a tax deduction at the same time and for the same amount.

  Upon exercise of a non-qualified stock option (including performance stock
options), the employee will realize ordinary income in an amount measured by
the excess, if any, of the fair market value of unrestricted shares on the
date of exercise over the option price, and the Company will be entitled to a
corresponding deduction. Restricted stock, if any, acquired through the
exercise of stock options will be subject to the tax treatment described below
for restricted stock.

  An employee who has been granted a performance share award will not realize
taxable income at the time of grant, and the Company will not be entitled to a
deduction at such time. Whether a performance share award is paid in cash or
shares of common stock, the employee will have ordinary income and the Company
will have a corresponding deduction when payout is made. The measure of such
income and deduction for any shares of Common Stock will be their fair market
value at the time the performance share award is paid out. There will be a
charge against corporate earnings each year for a portion of the payment
expected to be made.

  An employee receiving restricted stock may be taxed in one of two ways: (i)
the employee pays tax when the restrictions lapse, or (ii) the employee makes
a special election to pay tax in the year the grant is made. The value of the
award for tax purposes is the fair market value of the shares of Common Stock
at the applicable time. This value is taxed as ordinary income and is subject
to income tax withholding. When the employee is taxed, the Company receives a
tax deduction at the same time and for the same amount. If an employee elects
to be taxed at grant, when the restrictions lapse there

                                      30
<PAGE>

will be no further tax consequences attributable to the awarded stock until
sale or other disposition of the stock. However, dividends in cash and stock
will be treated as follows: (i) if the above special tax election has been
made, cash dividends paid to the employee will be taxable dividend income to
the employee when paid, but the Company will not be entitled to any
corresponding deduction; and (ii) if such election has not been made, the
employee will have taxable compensation income and the Company a corresponding
deduction when the dividends are paid.

  When a restricted stock award is made, the value of the stock at the date of
grant will be charged against corporate earnings pro-rata over the restriction
period. If the employee does not elect to be taxed on the grant of his
restricted stock award, a tax deduction by the Company at the expiration of
the restriction period would be greater than the amount charged to earnings if
the price of common stock has increased or less if the price of common stock
has declined.

  Section 162(m) of the Internal Revenue Code of 1986, as amended, may impose
limitations on the ability of the Company to obtain tax deductions for
compensation of more than $1 million per year to its chief executive officer
or any of its other four most highly-compensated officers. The Company
believes that the Management Incentive Program meets all of the requirements
of Section 162(m), except for restricted stock awards under the LTIP and cash
dividends.

Amendment and Termination

  The Board (without participation by any employee directors) may terminate
the Management Incentive Program at any time and, with the consent of an
individual participant, the Board or Committee may cancel, reduce, or alter
the number of outstanding awards thereunder. The Board (without participation
by any employee directors) may amend or suspend or, if suspended, reinstate,
the Management Incentive Program in whole or in part, provided, however, that
without stockholder approval, the Board may not (i) increase the maximum
number of shares authorized for awards or as restricted stock or performance
shares under the Incentive Program, (ii) change the minimum exercise price for
stock options or minimum grant price for TLSARs, or (iii) extend the
termination dates of the LTIP or PSOP.

  Under the amendments, Section 13 of the LTIP is amended to provide that the
Board of Directors may not, without stockholder approval, increase the maximum
cash bonus payable to any person under a Bonus Award.

  The Board of Directors unanimously recommends a vote FOR approval of the
amendments to the 1998 Management Incentive Program. The proxy holders will
vote all proxies received FOR approval unless instructed otherwise.

  The affirmative vote 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
approval of the amendments to the 1998 Management Incentive Program.

                                    ITEM 5.
                             STOCKHOLDER PROPOSAL

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

  "WHEREAS: Unocal has had historic and on-going environmental violations,
especially at a number of California's pristine locations (e.g. Guadalupe
spill, the largest in California, costing $43.8M), Avila Beach spill (killing
a town economically--costing up to $200 million), San Francisco Bay spill
(costing $83 million with a possible $50 million more), and Molycorp Mountain
Pass Mine (failed to report toxic discharges). We believe this indicates a
lack of concern for the environment, has damaged Unocal's image and caused
financial loss;

  WHEREAS: We believe that Unocal has further damaged its image by its
association with the repressive government of Burma [Myanmar] and the
consequent litigation brought against it by citizens of Burma alleging our
company's involvement in the egregious human rights violations committed there
as reported by the United Nations, The U.S. State Department, Amnesty
International, Human Rights Watch Asia and other human rights organizations;

  WHEREAS: We believe that Unocal has failed to observe its own Statement of
Principles (recently revised under the title of Guiding Principles) which
requires the Company to: "Conduct business in a way that engenders pride in
our employees and respect from the world community. . .communicate openly and
honestly.............improve the quality of life in the communities where we do
business.....protect the environment. . .be a good corporate citizen and a good
friend of the people of our host country." Also, such conduct undercuts the
Global Sullivan Principles which Unocal recently endorsed.

  These Global Sullivan Principles explicitly commit endorsing companies to
eight basic principles including the following: "We will express our support
for universal human rights and particularly those of our employees, the
communities within which we operate, and parties with whom we do business."

  One important way to insure that any company is serious about its own Code,
or pursuing Principles like the Global Sullivan Principles, is to provide
incentives to executives through their compensation formula to meet those
goals.

  BE IT RESOLVED: That the Board of Directors appoint a special committee of
the Board consisting solely of independent Board Members to review ways to
link executive compensation with the Company's ethical and social performance,
and in particular with Unocal's Guiding Principles and to report to the
shareholders the results of this review. This report may omit confidential
information and be prepared at a reasonable cost.

                             Supporting Statement

  We believe linking the compensation and bonus packages of Unocal's
executives to our Company's ethical and social performance is timely and
necessary. It sends a message that Unocal is serious about excellence in these
areas just as meeting financial and business goals are rewarded.

  Many other companies, including Kodak, Bristol Myers Squibb, IBM and Proctor
& Gamble, have social responsibility goals and performance reflected in their
compensation formula.

<PAGE>

                           DIRECTORS' RECOMMENDATION

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

  Unocal already provides a report to stockholders by the Management
Development and Compensation Committee, comprised entirely of independent
directors. The report, beginning on page 10 of this proxy statement, explains
the criteria for CEO and executive officer compensation. Many aspect of an
executive's performance, including ethical behavior and social responsibility,
are utilized in determining compensation.

  Unocal also has a Corporate Responsibility Committee comprised entirely of
outside directors that reviews health and environmental issues, as well as
ethical conduct. The Corporate Responsibility Committee of the Board of
Directors plays a key oversight role in ensuring that Unocal and its
executives live up to the Company's commitment to being a good global citizen.
This committee of outside Directors regularly shares information about the
Company's corporate responsibility efforts with the full Board. A report on
corporate responsibility was mailed to all stockholders in 1999.

  Contrary to the implications in the stockholder's proposal, the Company has
not been involved in "egregious human rights violations" in Myanmar or
anywhere else. Unocal is proud of its human rights record. We are working to
help advance and promote respect for human rights through action, education,
assistance and economic engagement wherever we work. In Myanmar, where Unocal
is an investor in the Yadana natural gas pipeline project, the Company is
helping fund an extensive socio-economic program that has brought doctors,
schools, roads, water and sanitation systems, as well as a host of sustainable
economic opportunities to the 40,000 villagers in the pipeline vicinity. Two
internationally respected human rights experts, Reverend Richard W. Timm, CSF
and Justice K. M. Subhan inspected conditions along the pipeline route in
January 1998. They concluded that the lives of people in each village they
visited are better because of the Yadana Project, and that the project should
be a model for other international companies.

  Unocal is committed to being a good corporate citizen by operating in a way
that is socially responsible, and that contributes to economic prosperity.
Environmental performance is also a key aspect of our Operations Management
System. Our efforts focus on operating efficiently and effectively, preventing
pollution and producing clean energy. This is true in Southeast Asia, the
United States, and anywhere else where Unocal has business interests.

Our Position

  We believe that this proposal is unnecessary. The Board's Management
Development and Compensation Committee, consisting of non-employee directors,
regularly evaluates executive performance and provides a report in the proxy
statement to all stockholders each year. Unocal's Corporate Responsibility
Program supports a broad range of humanitarian and community programs,
including programs in Southeast Asia. The Board's Corporate Responsibility
Committee regularly reviews the company's policies, practices and programs
related to health, environment, safety, human resources, community affairs and
development, and ethical conduct.

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

  The affirmative vote 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 name and address of the
proponents of the proposal and information about their ownership of Unocal
common stock promptly upon receipt of an oral or written request to the
Secretary of the Company.

stockholders as shall have been properly brought before the meeting pursuant

Directors, or by a stockholder or a beneficial owner of the 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.

purchase in the open market or from a third party, the amount of the Purchase
Loan. The Committee shall give each Participant written notice prior to the

Program. Any Participant who does not elect to purchase at least the minimum

forfeit any rights under the Program with respect to such Award, including,
without limitation, any right to receive a Purchase Loan.

                                      A-3
<PAGE>

8. Purchase Loans

  a. General. The Company shall extend a Purchase Loan to a Participant upon
exercise of an Award subject to the terms and conditions set forth in this
Section 8. The original principal amount of the Purchase Loan shall be equal
to the total purchase price of the Stock. Such Purchase Loan shall be
evidenced by a Purchase Note with full recourse against the maker. The
obligations of each Participant under the Purchase Loan shall be unconditional
and absolute and, without limiting the generality of the foregoing, shall not
be released, discharged or otherwise affected by any change in the existence,
structure or ownership of the Company, or any insolvency, bankruptcy,
reorganization or other similar proceeding affecting the Company or its assets
or the market value of the Stock or any resulting release or discharge of any
obligation of the Company or the existence of any claim, set-off or other
rights which any Participant may have at any time against the Company or any
other person, whether in connection with the Program or with any unrelated
transactions, provided that nothing herein shall prevent the assertion of any
such claim by separate suit or counterclaim.

  Notwithstanding anything to the contrary in this Section 8, the Company
shall not be required to make any Purchase Loan to a Participant if the making
of such Purchase Loan will (i) cause the Company to violate any covenant or
similar provision in any indenture, loan agreement or other agreement, or (ii)
violate any applicable federal, state or local law, provided, that the failure
to make such Purchase Loan shall be deemed to revoke the acceptance and
exercise of a related Award unless otherwise specified by the Participant.
Notwithstanding anything to the contrary in this Section 8, the terms and
repayment provisions of the Purchase Note shall conform with the applicable
rules and regulations of the Federal Reserve Board then in effect.

  b. Unsecured Loan. Payment of the Purchase Loan shall not be secured,
directly or indirectly, by a pledge of the shares of Stock acquired by the
Participant upon the exercise of the Award to which the Purchase Loan relates.

  c. Interest. Interest on the principal balance of the Purchase Loan will
accrue annually, in arrears, at the Interest Rate. Except as provided in the
Purchase Loan and related Purchase Note, interest shall be added to the
balance of the Purchase Loan. To the extent that a Participant receives cash
dividends or other distributions paid in cash on Stock purchased under this
Program, the Participant shall prepay the related Purchase Loan with the full
pre-tax amount of such dividend or distribution received within ten (10) days
of receipt. Such prepayments shall first be applied to pay accrued interest on
the Purchase Loan and then to reduce the principal balance due on the Purchase
Loan.

  d. Term. The term of the Purchase Loan for any Participant shall begin on
such Participant's Purchase Date and, subject to prepayment as provided in
this Section 8, shall have a final maturity date on the eighth (8th)
anniversary of the Purchase Date.

  e. Payment Schedule. Except as provided in Section 3, and subject to
prepayment as provided in this Section 8, no payments of either principal or
interest shall be due under the Purchase Loan during the first five (5) years
following the Purchase Date. The principal balance of the Purchase Loan
(including accrued but unpaid interest) outstanding after any prepayments
following the end of such five-year period, if any (the "Remaining Balance"),
shall be payable in three (3) equal annual installments on the sixth (6th),
seventh (7th) and eighth (8th) anniversaries of the Purchase Date, with
interest on the unpaid Remaining Balance payable annually in arrears, on each
such anniversary.

  f. Optional Prepayments. A Participant may prepay all or any portion of the
Purchase Loan at any time. Any prepayments made to the Company pursuant to
this Section 8(f) shall first be applied to pay accrued interest on the
Purchase Loan and then to reduce the principal balance due on the Purchase
Loan. Any prepayment of the balance of the Purchase Loan shall be applied to
the principal payments due thereon in chronological order of maturity.

                                      A-4
<PAGE>

  g. Prepayment Obligations Upon Voluntary Termination or Termination for
Cause. Upon a termination of employment that is determined by the Committee to
be a termination for Cause or a Voluntary Termination, any outstanding balance
on the Purchase Loan (including any accrued and unpaid interest) shall become
due and payable on the 60th day following such termination of employment.
Prepayment of a Purchase Loan shall not be required in the event of any other
termination of employment (including termination due to death, Disability,
Retirement, and termination without Cause).

  h. Purchase Loan Forgiveness. For Awards granted during the year 2000, the
Committee shall provide for the partial forgiveness of the Purchase Loan in
the case of a Participant who has died or becomes Disabled to the extent that,
at the maturity date of the Purchase Loan, the outstanding balance of the
Purchase Loan (including any accrued and unpaid interest), increased by the
amount of any repayments of principal previously made by the Participant, is
greater than the sum of (i) the Fair Market Value of the number of shares of
Stock purchased by the Participant pursuant to the exercise of the Award plus
(ii) the amount of the Performance Bonus paid to the Participant under the
Long-Term Incentive Plan of 1998 for the four-year award period ending on
December 31, 2003 plus (iii) interest on such Performance Bonus at the
Interest Rate from December 31, 2003 to the repayment date.

9. General

  a. Government and Other Regulations. The obligation of the Company with
respect to the grant and exercise of Awards shall be subject to all applicable
laws, rules, and regulations, and to such approvals by governmental agencies
as may be required. The Company shall be under no obligation to register under
the Securities Act of 1933, as amended ("Act") any of the shares of Stock
issued under the Program. If the Stock issued under the Program may in certain
circumstances be exempt from registration under the Act, the Company may
restrict the transfer of such shares in such manner as it deems advisable to
ensure the availability of any such exemption.

  b. Tax Withholding. The Company or a Subsidiary, as appropriate, shall have
the right to deduct from any benefits due under the Program or other amounts
payable to a Participant an amount sufficient to satisfy any federal, state or
local withholding requirements applicable to such benefits. In addition, as a
condition to payment or delivery of any benefit hereunder, including without
limitation, any forgiveness of any portion of a Purchase Loan pursuant to
Section 3 or Section 8(h), the Company or a Subsidiary, as appropriate, may
require a Participant to pay to the Company or Subsidiary the amount of any
applicable federal, state or local withholding taxes.

  c. Claim to Awards and Employment Rights. No Employee or other person shall
have any claim or right to be granted an Award under the Program. Neither this
Program nor any action taken hereunder shall be construed as giving any
Employee any right to be retained in the employ of the Company or a
Subsidiary.

  d. Applicable Law. This Program, any Award Agreements and all other related
documents shall be governed by and construed in accordance with the laws of
the State of California without regard to the application of the conflicts of
laws provisions thereof except for such matters as are subject to the General
Corporation Law of Delaware.

  e. Inurement of Rights and Obligations. The rights and obligations under the
Program and any related Award Agreements shall inure to the benefit of, and

and their beneficiaries.

  f. Non-exclusivity of Program. Nothing in this Program shall limit or be
deemed to limit the authority of the Board or the Committee to grant awards or
authorize any other compensation, with or without reference to Stock, under
any other plan or authority.

  g. Severability; Validity. This Program is intended to qualify under Rule
16b-3. If any of the terms or provisions of this Program conflict with the
requirements of Rule 16b-3, then such terms and provisions shall be deemed
inoperative to the extent they so conflict with such requirements. In the
event that any provision of the Program or any related Award Agreement or
other related document is held to be invalid, void or unenforceable, the same
shall not affect, in any respect whatsoever, the validity of any other
provision of the Program or any related Award Agreement or other document.

  h. Indemnification. Each person who is or shall have been a member of the
Committee or the Board, including the Employee directors, shall be indemnified
and held harmless by the Company against and from any loss, cost, liability,
or expense that may be imposed upon or reasonably incurred by him in
connection with or resulting from any claim, action, suit, or proceeding to
which he may be a party or in which he may be involved by reason of any action
or failure to act under the Program and against and from any and all amounts
paid by him in satisfaction of judgment in any such action, suit or proceeding
against him. He shall give the Company an opportunity, at its own expense, to
handle and defend the same before he undertakes to handle and defend it on his
own behalf. The foregoing right of indemnification shall not be exclusive of
any other rights of indemnification to which such persons may be entitled
under the Company's Certificate of Incorporation or Bylaws, as a matter of
law, or otherwise, or any power that the Company may have to indemnify them or
hold them harmless.

  i. Reliance on Reports. Each member of the Committee and the Board,
including the Employee directors, shall be fully justified in relying or
acting in good faith upon any report made by the independent public
accountants of the Company and its Subsidiaries and upon any other information
furnished in connection with the Program by any person or persons other than
himself. In no event shall any person who is or shall have been a member of
the Committee or of the Board be liable for any determination made or other
action taken or any omission to act in reliance upon any such report or
information or for any action taken, including the furnishing of information,
or failure to act, if in good faith.

  j. Relationship to Other Benefits. No payment under the Program shall be
taken into account in determining any benefits under a pension, retirement,
profit sharing, group insurance or other benefit plan of the Company or any
Subsidiary.

  k. Expenses. The expenses of administering the Program shall be borne by the
Company and its Subsidiaries.

  l. Pronouns. Masculine pronouns and other words of masculine gender shall
refer to both men and women.

  m. Titles and Headings. The titles and headings of the sections in the

control.

10. Changes in Capital Structure

  Any agreements evidencing Awards shall be subject to adjustment by the
Committee as to the number and price of shares of Stock or other
considerations subject to such Awards in the event of changes in the
outstanding Stock by reason of stock dividends, stock splits,
recapitalizations, reorganizations, mergers, consolidations, combinations,
exchanges, or other relevant changes in capitalization occurring after the
Date of Purchase of any such Awards. In the event of any such

                                      A-6
<PAGE>

change in the outstanding Stock, the aggregate number of shares available
under the Program and the number of shares issued under any Award shall be
appropriately adjusted by the Committee, whose determination shall be
conclusive.

11. Amendments and Termination

  The Board may at any time amend, suspend or terminate the Program subject to
the provisions of this Section 11. No amendment, suspension or termination of
the Program shall, without the consent of the Participant, adversely affect
such Participant's rights under the Program in any material respect. In
addition, without further stockholder approval, the Board shall not:

  a. Increase the maximum number of shares which may be issued under the
Program, except as provided in Section 10;

  b. Change the Program to permit a purchase of Stock at a price less than

under the Plan for Employees other than executive officers to a committee of
the Board of Directors of the Company.

  No member of the Committee, while serving as such, shall be eligible to
receive an Award under the Plan. The Committee shall have the authority,
subject to the provisions of the Plan, to establish, adopt, or revise such
rules and regulations and to make all such determinations relating to the Plan
as it may deem necessary or advisable in the administration of the Plan. The
Committee's interpretation of the Plan or any Awards granted pursuant thereto
and all decisions and determinations by the Committee with respect to the Plan
shall be final, binding, and conclusive on all parties.

                                      B-2

5. Determination of Bonus Pool and Awards

  The committee shall elect Employees to participate in the Plan. The bonus
pool for each Award period shall be an amount equal to two percent (2%) of the
Company's Net Cash Provided By Operating Activities during the Award Period.
The aggregate amount of Awards paid, without giving effect to any augmentation
upon deferral into restricted stock, under the Plan may not exceed this bonus
pool.

  No later than 90 days following the beginning of each Award Period, the
Committee shall establish the level of Awards for those executive officers
whose compensation may be subject to the limitation on deductibility under
Section 162(m) of the Code, as determined by the Committee in its sole
discretion. The amount of each such Award shall be expressed as a percentage
of the bonus pool. The committee shall have the sole discretion to determine
whether the full amount of such Awards will be paid to such participants and
may reduce, but may not increase, the amount payable under an Award based on
such criteria as the Committee, in its sole discretion may determine, which
criteria may include, but shall not be limited to, one or more of the
following: Comparative Return to Stockholders, ROCE, Future Year Value
Creation and individual performance.

  The Committee shall also establish individual target Awards for the
remaining participants based such criteria as the Committee, in its sole
discretion may determine, which criteria may include, but shall not be limited
to, one or more of the following: Comparative Return to Stockholders, ROCE,
Future Year Value Creation and salary grade. Subject to the amount of the
bonus pool available after payment of the Awards described in the preceding
paragraph, the Committee shall have the sole discretion to determine the
actual amounts paid out under these Awards, which amounts may be greater than
or less than the target amounts, on the basis of factors such as, but not
limited to, the following:

  a. Comparison of actual operational or financial results to plans or goals,
adjusted for external factors such as changes in market prices,

  b. Individual performance of Employees selected to participate in the Plan,
and

  c. Reasonableness of total cash compensation.

  Notwithstanding any other provision of the Plan, the maximum cash Award
payable to a participant in the Plan in any calendar year shall be 0.25% of
the Company's Net Cash Provided By Operating Activities for the calendar year
or, if less, $2,000,000; provided, however, that any portion of an Award
deferred in the form of Restricted Stock may be adjusted pursuant to Section
6.

6. Payment and Deferral of Awards

  Awards under the Plan shall be paid in cash from general funds of the
Company in a manner to be prescribed by the Committee. An Award may be paid
all or in part as Restricted Stock (a "Restricted Stock Award") as determined
by the Committee or pursuant to an annual election of the recipient under such
terms as the Committee may establish. In consideration for forgoing cash
compensation, the Committee may, in its discretion, make a Restricted Stock
Award with a total dollar value greater than the Award deferred, provided that
any such increase shall not exceed 100% of the dollar value of the Award
deferred. The number of shares of Restricted Stock issued in consideration of
Awards deferred shall be based on Fair Market Value, after any such increase
described above. The Committee may also permit participants in the Plan to
defer payment of cash Awards pursuant to a cash deferral program on such
terms, including interest which may be credited thereon, as the Committee may
approve in its sole discretion.

  a. Restriction Period. At the time a Restricted Stock Award is made, the
Committee shall establish a period of time (the "Restriction Period")
applicable to such Restricted Stock Award, which

                                      B-3
<PAGE>

shall be not less than four years. Each Restricted Stock Award may have a
different Restriction Period, at the discretion of the Committee. In the event
of a public tender for all or any portion of the Stock of the Company; in the
event that any proposal to merge, consolidate or otherwise combine the Company
with another company is submitted for stockholder approval; or if another
situation exists that the Committee determines is similar thereto, the
Committee may in its sole discretion change or eliminate the Restriction
Period, and it may also include provisions for such events in the Restricted
Stock Award.

  b. Other Terms and Conditions. Subject to the terms of the Plan, the
Committee shall determine and may amend the terms and conditions applicable to
any particular Restricted Stock Award. The Holder shall have the right to
enjoy all stockholder rights during the Restriction Period with the exception
that:

    (i) The Holder may not sell, transfer, pledge, exchange, hypothecate, or
  otherwise dispose of the Stock during the Restriction Period, except as
  permitted pursuant to Section 7(e).

    (ii) Any breach of the terms and conditions established by the Committee
  pursuant to the Restricted Stock Award shall cause a forfeiture of the
  Restricted Stock Award, and any dividends withheld thereon.

    (iii) Cash and stock dividends may either be currently paid or withheld
  by the Company for the Holder's account. At the discretion of the
  Committee, interest may be paid on the amount of cash dividends withheld,
  including cash dividends on stock dividends, at a rate and subject to such
  terms as determined by the Committee.

  c. Termination of Employment. Unless the Committee determines otherwise, in
the event a Holder terminates employment during a Restriction Period, a
Restricted Stock Award will be subject to the following:

    (i) Termination determined by the Committee to be at the convenience of
  the Company and not for "cause" or for performance inadequacy:

    --The Restricted Stock Award would be payable in full and distributed
      as soon as practicable after termination.

    (ii) Resignation or discharge other than pursuant to Section 6(c)(i):

    --The Restricted Stock Award would be completely forfeited.

    (iii) Retirement, other than early retirement, pursuant to the Company
  retirement plan then in effect:

    --The Restricted Stock Award would be payable in full and distributed
      as soon as practicable after retirement.

    (iv) Early Retirement:

    --If at the Holder's request, the Restricted Stock Award would be
      completely forfeited.

    --If at the Company's request, the Restricted Stock Award would be
      payable in full and distributed as soon as practicable after
      retirement.

    (v) Death or Total and Permanent Disability:

    --The Restricted Stock Award would be payable in full and distributed
      as soon as practicable after death or disability.

  d. Distribution. Except as provided in Section 6 (a), in no event shall
Stock be delivered prior to six months from the date of grant.

                                      B-4
<PAGE>

7. General

  a. Government and Other Regulations. The obligation of the Company to make
payment of distributions under the Plan shall be subject to all applicable
laws, rules, and regulations, and to such approvals by governmental agencies
as may be required. The Company shall be under no obligation to register under
the Securities Act of 1933, as amended ("Act") any of the shares of Stock paid
under the Plan. If the shares paid under the Plan may in certain circumstances
be exempt from registration under the Act, the Company may restrict the
transfer of such shares in such manner as it deems advisable to ensure the
availability of any such exemption.

  b. Tax Withholding. The Company or a Subsidiary, as appropriate, shall have
the right to deduct from all Awards paid in cash any federal, state or local
taxes as required by law to be withheld with respect to such cash payments,
and, in the case of Awards paid in Stock, the Employee or other person
receiving such Stock may be required to pay to the Company or a Subsidiary, as
appropriate, the amount of any such taxes which the Company or Subsidiary is
required to withhold with respect to such Stock. The Company may, in lieu of
requiring cash payment of any such taxes, elect to withhold from Stock
payments a number of whole shares of Stock whose value is at least equal to
the amount of such taxes. Valuation for this purpose shall be the average of
the reported high and low prices of the Stock as reported in the New York
Stock Exchange Composite Transactions quotations for the first trading date
following the Award or Restriction Period, unless the Committee determines
that it is appropriate to value the Stock on some other date for this purpose.

  c. Claim to Awards and Employment Rights.  No Employee or other person shall
have any claim or right to be granted an Award under the Plan. Neither this
Plan nor any action taken hereunder shall be construed as giving any Employee
any right to be retained in the employ of the Company or a Subsidiary.

  d. Beneficiaries. Any payment due under the Plan to a deceased participant
shall be paid to the beneficiary designated by the participant and filed with
the Committee. If no such beneficiary has been designated, payment shall be
made to the participant's surviving spouse. If a participant does not
designate a beneficiary or have a surviving spouse, payment shall be made to
the participant's legal representative. A beneficiary designation may be
changed or revoked by a participant at any time, provided the change or
revocation is filed with the Committee.

  e. Nontransferability. A person's rights and interests under the Plan,
including amounts payable, may not be assigned, pledged, or transferred
except, in the event of an Employee's death, to a designated beneficiary as
provided in the Plan, or in the absence of such designation, by will or the
laws of descent and distribution, except as may be permitted by the Committee
in its sole discretion. The Committee, in its sole discretion, may permit
transfers of Restricted Stock to an Employee's family members and entities
(including trusts, corporations, partnerships, and limited liability
companies) which are established for the exclusive benefit of or are owned
solely by family members and may prescribe such rules and limitations as it
deems appropriate regarding such transfers, taking into account tax
considerations, the impact of Section 16 of the Securities Exchange Act of
1934, the need to register shares under the Securities Act of 1933 and any
applicable State Blue Sky Laws, and any other relevant considerations.

  f. Indemnification. Each person who is or shall have been a member of the
Committee or the Board, including the Employee directors, shall be indemnified
and held harmless by the Company against and from any loss, cost, liability,
or expense that may be imposed upon or reasonably incurred by him in
connection with or resulting from any claim, action, suit, or proceeding to
which he may be a party or in which he may be involved by reason of any action
or failure to act under the Plan and against and from any and all amounts paid
by him in satisfaction of judgment in any such action, suit or proceeding
against him. He shall give the Company an opportunity, at its own expense, to
handle

                                      B-5
<PAGE>

and defend the same before he undertakes to handle and defend it on his own
behalf. The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under
the Company's Certificate of Incorporation or Bylaws, as a matter of law, or
otherwise, or any power that the Company may have to indemnify them or hold
them harmless.

  g. Reliance on Reports. Each member of the Committee and the Board,
including the Employee directors, shall be fully justified in relying or
acting in good faith upon any report made by the independent public
accountants of the Company and its Subsidiaries and upon any other information
furnished in connection with the Plan by any person or persons other than
himself. In no event shall any person who is or shall have been a member of
the Committee or of the Board be liable for any determination made or other
action taken or any omission to act in reliance upon any such report or
information or for any action taken, including the furnishing of information,
or failure to act, if in good faith.

  h. Relationship to Other Benefits. No payment under the Plan shall be taken
into account in determining any benefits under any pension, retirement, profit
sharing, group insurance or other benefit plan of the Company or any
Subsidiary, unless specifically so provided under such plan.

  i. Lapse of Awards. To the extent a Restricted Stock Award lapses or the
rights of its Holder terminate or are forfeited, any shares of Stock subject
to such Award which are forfeited shall again be available to be granted as an
Award. Upon satisfaction of tax withholding obligations in connection with any
payment made or benefit realized under this Plan by the transfer or
relinquishment of Stock, there shall be deemed to have been issued or
transferred under this Plan only the number of shares of Stock actually issued
or transferred by the Company less the number of shares of Stock so transferred
or relinquished.

  j. Expenses. The expenses of administering the Plan shall be borne by the
Company and its Subsidiaries.

  k. Pronouns. Masculine pronouns and other words of masculine gender shall
refer to both men and women.

  l. Titles and Headings. The titles and headings of the sections in the Plan
are for convenience of reference only and in the event of any conflict, the
text of the Plan, rather than such titles or headings, shall control.

8. Changes in Capital Structure

  Restricted Stock Awards and any agreements evidencing such Awards shall be
subject to adjustment by the Committee as to the number and price of shares of
Stock or other considerations subject to such Awards in the event of changes
in the outstanding Stock by reason of stock dividends, stock splits,
recapitalizations, reorganizations, mergers, consolidations, combinations,
exchanges, or other relevant changes in capitalization occurring after the
date of grant of any such Award. In the event of any such change in the
outstanding Stock, the aggregate number of shares available under the Plan may
be appropriately adjusted by the Committee, whose determination shall be
conclusive.

9. Amendments and Termination

  The Board may at any time terminate the Plan, and with the express written
consent of a Holder, the Board or Committee may cancel, reduce or otherwise
alter his outstanding Awards thereunder if, in its judgment, the tax,
accounting, or other effects of the Plan or potential payouts thereunder would
not be in the best interest of the Company. The Board may, at any time, or
from time to time, amend or suspend and, if suspended, reinstate, the Plan in
whole or in part, provided, however, that without

                                      B-6
<PAGE>

further stockholder approval the Board shall not permit the granting of an
Award to a person who is not an Employee or increase the maximum number of
shares which may be issued pursuant to Restricted Stock Awards under the Plan
or Program, except as provided in Section 8.

Upon the full or partial payment of any option price by the transfer to the
Company of Stock or upon satisfaction of tax withholding obligations in

  One or more Options may be granted to any Employee. No person may be granted
during any 12-month period Options to acquire more than 100,000 shares of
Stock under this Plan. Each Option so granted shall be subject to the
following conditions:

price shall be payable in a combination of cash and/or shares of Stock
acceptable to the Committee valued at the Fair Market Value as of the date the
Option is exercised, including (if permitted by the Company) proceeds from the
sale of Stock acquired by exercise of the Option (a cashless exercise).

  c. Restrictions on Shares Acquired. The Committee may impose restrictions
for a specified period (the "Restriction Period") on a portion or all of the
shares acquired through exercise of Options in order to promote the share
ownership objectives of the Plan.

  d. Stock Option Agreement. Each Option granted under the Plan shall be
evidenced by a "Stock Option Agreement" between the Company and the Holder of
the Option containing provisions determined by the Committee, which shall
include the following terms and conditions:

    (i) Any Option or portion thereof that is exercisable shall be
  exercisable for the full amount or for any part thereof, except as
  otherwise determined by the grant.

    (ii) Every share purchased through the exercise of an Option shall be
  paid for in full prior to delivery of stock or, if permitted by the
  Company, through a cashless exercise. Each Option shall cease to be
  exercisable, as to any share, when the Holder purchases the share or when
  the Option lapses.

    (iii) Options shall not be transferable by the Holder except by will or
  the laws of descent and distribution and shall be exercisable during the
  Holder's lifetime only by the Holder, his guardian or legal representative,
  except as permitted pursuant to Section 11(e).

    (iv) In consideration for the granting of each Option, the Holder shall
  agree to remain in the employment of the Company or one or more of its
  Subsidiaries at the pleasure of the Company or such Subsidiary for a
  continuous period of at least one year after the Date of Grant. At the
  discretion of the Committee, this requirement may be waived if the Holder
  during said one-year period becomes incapacitated or enters the active
  service of the military forces of the United States or other United States
  service connected with national defense activities. The Holder agrees that
  during such employment, he will devote his entire time, energy and skills
  to the service and interest of the Company or such Subsidiary subject to
  vacations, sick leave, and other absences in accordance with the regular
  policies of the Company and its Subsidiaries.

    (v) Notwithstanding any other provision of the Plan, in the event of a
  public tender for all or any portion of the Stock of the Company; in the
  event that a proposal to merge, consolidate, or otherwise combine with
  another company is submitted for stockholder approval; or another situation
  exists which the Committee determines is similar thereto, the Committee may
  in its sole discretion declare outstanding Options to be immediately
  exercisable, and it may also include provisions for such events in the
  Stock Option Agreement.

    (vi) The Committee may in its sole discretion declare that outstanding
  Options which are immediately exercisable, but have not been exercised,
  will terminate upon (i) a dissolution of the Company, (ii) a merger,
  reorganization, consolidation or similar event that the Company does not
  survive, or (iii) the consummation of a merger, reorganization,
  consolidation or similar event approved by the Board of Directors, and it
  may also include provisions for such events in the Stock Option Agreement.

  e. Other Terms and Conditions. Each Option shall become exercisable in such
manner (which may include cumulative annual or other installments) on or after
such date or dates and within such period or periods, not to exceed ten years
from its Date of Grant, as set forth in the Stock Option Agreement.

8. Performance Shares

  All outstanding grants of Performance Share Awards under the Long-Term
Incentive Plans of 1985 and 1991 shall be subject to the terms of this Plan,
subject to any required consent of the Holder.

  a. Awards. Grants of Performance Shares may be made by the Committee during
the term of the Plan, which shall be credited to a Performance Share account
to be maintained for each such

                                     B-11
<PAGE>

Holder. Each Performance Share shall have a value equivalent to one share of
Stock of the Company. Grants of Performance Shares shall be deemed to have
been made on January 1 of the calendar year in which grants are made. In
determining the size of Awards, the Committee may take into account a Holder's
responsibility level, performance, potential, cash compensation level, and the
Fair Market Value of the Company's Stock at the time of Awards, as well as
such other considerations as it deems appropriate. No person may receive more
than 30% of the aggregate number of Performance Shares granted or more than
25,000 Performance Shares in any 12-month period.

  b. Right to Payment of Performance Shares. Following the end of the Award
Period, the Committee shall establish and determine a percentage by which the
Performance Shares awarded shall be multiplied, based on the Company's
Comparative Return to Stockholders, and each Holder's Performance Shares shall
be multiplied by that percentage ("Payout Shares"). In no event shall such
percentage exceed 200%.

  Each Holder of Performance Shares shall be entitled at the end of an Award
Period to a dollar amount equal to the Fair Market Value of his Payout Shares
as of the Valuation Date. In no event shall the Fair Market Value of the
Payout Shares exceed 400% of the Fair Market Value of the initial Award of
Performance Shares.

  c. Timing and Form of Payment. No payment of Performance Shares shall be
made prior to the end of an Award Period, but shall be made as soon as
practicable thereafter. The Committee may authorize payment in a combination
of cash and/or Stock, as it deems appropriate. Stock may be withheld to
satisfy the tax obligations resulting from the Award. Stock delivered in
payment of Performance Shares may be shares purchased for the account of the
Holder or authorized and unissued shares, or any combination thereof. The
number of shares of Stock to be paid in lieu of cash will be determined by
dividing the portion of the payment not paid in cash by:

    (i) The average of the reported high and low prices of the Stock as
  reported in the New York Stock Exchange Composite Transactions quotations
  on the date on which the shares are issued, or

    (ii) The price per share paid for shares purchased for a Holder's account
  should the Company purchase shares on behalf of a Holder.

  Notwithstanding any other provision of the Plan, in the event of any public
tender for all or any part of the Stock of the Company; in the event that any
proposal to merge, consolidate or otherwise combine the Company with another
company is submitted for stockholder approval; or another situation exists
which the Committee determines is similar thereto, the Committee may in its
sole discretion declare any Award Period ended as of a specific date and
accelerate full payments of such Awards accordingly, and it may also include
provisions for such events in the Performance Share Award. The Committee shall
determine a Comparative Return to Stockholders for the reduced Award Period.

  d. Termination of Employment. In the event a Holder terminates employment
during an Award Period, payout would be as follows:

    (i) Termination determined by the Committee to be at the convenience of
  the Company and not for Cause or for performance inadequacy:

    --Payout would be at the end of the Award Period and prorated for
      service during the period.

    (ii) Resignation or discharge other than pursuant to Section 8(d)(i):

    --The Award would be completely forfeited.

    (iii) Retirement:

    --Payout would be at the end of the Award Period and prorated for
      service during the period.

                                     B-12
<PAGE>

    (iv) Early retirement:

    --If at the Holder's request, the Award would be completely forfeited.

    --If at the Company's request, payout would be at the end of the Award
      Period and prorated for service during the period.

    (v) Death or Total and Permanent Disability:

    --Payout would be at the end of the Award Period and prorated for
      service during the period.

9. Restricted Stock Awards

  a. Restriction Period. A Restricted Stock Award may be granted by the
Committee to any Employee. At the time a Restricted Stock Award is made, the
Committee shall establish a period of time (the "Restriction Period")
applicable to such Award which shall be not less than four years. Each
Restricted Stock Award may have a different Restriction Period, at the
discretion of the Committee. In the event of a public tender for all or any
portion of the Stock of the Company; or in the event that any proposal to
merge, consolidate, or otherwise combine the Company with another company is
submitted for stockholder approval; or another situation exists which the
Committee determines is similar thereto, the Committee may in its sole
discretion change or eliminate the Restriction Period, and it may also include
provisions for such events in the Restricted Stock Award.

  b. Other Terms and Conditions. Subject to the terms of the Plan, the
Committee shall determine the terms and conditions applicable to any
particular grant of a Restricted Stock Award. The Holder shall have the right
to enjoy all stockholder rights during the Restriction Period with the
exception that:

    (i) The Holder may not sell, transfer, pledge, exchange, hypothecate, or
  otherwise dispose of the Stock during the Restriction Period, except as
  permitted pursuant to Section 11(e).

    (ii) Any breach of the terms and conditions established by the Committee
  pursuant to the Restricted Stock Award shall cause a forfeiture of the
  Restricted Stock Award, and any dividends withheld thereon.

    (iii) Cash and stock dividends may either be currently paid or withheld
  by the Company for the Holder's account. At the discretion of the
  Committee, interest may be paid on the amount of cash dividends withheld,
  including cash dividends on stock dividends, at a rate and subject to such
  terms as determined by the Committee.

  c. Termination of Employment. Unless the Committee determines otherwise, in
the event a Holder terminates employment during a Restriction Period, a
Restricted Stock Award will be subject to the following:

    (i) Termination determined by the Committee to be at the convenience of
  the Company and not for Cause or for performance inadequacy:

    --The Restricted Stock Award would be prorated for service during the
      Restriction Period and would be distributed as soon as practicable
      following termination.

    (ii) Resignation or discharge other than pursuant to Section 9(c)(i):

    --The Restricted Stock Award would be completely forfeited.

    (iii) Retirement:

    --The Restricted Stock Award would be prorated for service during the
      Restriction Period and would be distributed as soon as practicable
      following retirement.

                                     B-13
<PAGE>

    (iv) Early retirement:

    --If at the Holder's request, the Restricted Stock Award would be
      completely forfeited.

    --If at the Company's request, the Restricted Stock Award would be
      prorated for service during the Restriction Period and would be
      distributed as soon as practicable following early retirement.

    (v) Death or Total and Permanent Disability:

    --The Restricted Stock Award would be prorated for service during the
      Restriction Period and distributed as soon as practicable following
      death or disability.

10. Performance Bonuses

  a. Awards. Grants of Performance Bonus Awards may be made by the Committee
during the term of the Plan. Each Performance Bonus Award shall represent the
right to be paid a cash bonus if the goal or goals based on the Company's
Comparative Return to Stockholders for the Award Period are satisfied. Grants
of Performance Bonus Awards shall be deemed to have been made on January 1 of
the calendar year in which grants are made. At the time of granting a
Performance Bonus Award, the Committee shall establish (i) the goal or goals
based in part on the Company's Comparative Return to Stockholders and changes
to the price of the Company's common stock, (ii) a matrix to be used to
determine the cash amount, if any, that will be paid based on the extent that
such goal or goals are not achieved. In determining the range of possible
Performance Bonuses, the Committee may take into account a Holder's
responsibility level, cash compensation level, and the Fair Market Value of
the Company's Stock at the time of granting the Performance Bonus Awards, as
well as such other considerations as it deems appropriate. The maximum
Performance Bonus that may be paid to any person for any four-year Award
Period shall be $6.5 million. The maximum Performance Bonus that may be paid
to any person for any Award Period that is longer than four years shall be
$1.625 million multiplied by the number of years in such Award Period.

  b. Right to Payment of Performance Bonus. Following the end of the Award
Period, the Committee shall determine the amount of each Holder's Performance
Bonus in accordance with the performance matrix. In no event shall such
percentage exceed 100%.

  c. Timing and Form of Payment. No payment of Performance Bonuses shall be
made prior to the end of an Award Period, but shall be made as soon as
practicable thereafter.

  Notwithstanding any other provision of the Plan, in the event of a Change in
Control of the Company, the Committee shall declare any Award Period ended as
of the date of the Change in Control and accelerate payments of such
Performance Bonus Awards. The Committee shall determine the Comparative Return
to Stockholders and other factors in the matrix for the reduced Award Period
and the amount of Performance Bonuses payable based on such Comparative Return
to Stockholders, the change to the price of the Company's common stock, and
other performance criteria as if the full Award Period had been completed;
provided, however, that in no event shall a Holder's Performance Bonus be less
than 50% of the maximum amount under the Performance Bonus Award.

  d. Termination of Employment. In the event a Holder terminates employment
during an Award Period for a reason other than a Voluntary Termination or is
terminated without Cause, in either case as determined by the Committee, the
Performance Bonus Award shall remain outstanding and the Holder shall receive
the same Performance Bonus at the end of the Award Period based on the
Company's Comparative Return to Stockholders as if the Holder had remained
employed during the full Award Period.

  If a Holder terminates employment during an Award Period in a Voluntary
Termination or is terminated for Cause, in either case as determined by the
Committee, such Holder's Performance Bonus Award shall be forfeited.

                                     B-14
<PAGE>

11. General

  a. Government and Other Regulations. The obligation of the Company to make
payment of Awards in Stock or otherwise shall be subject to all applicable
laws, rules, and regulations, and to such approvals by governmental agencies
as may be required. The Company shall be under no obligation to register under
the Securities Act of 1933, as amended ("Act") any of the shares of Stock paid
under the Plan. If the Stock issued under the Plan may in certain
circumstances be exempt from registration under the Act, the Company may
restrict the transfer of such shares in such manner as it deems advisable to
ensure the availability of any such exemption.

  b. Tax Withholding. The Company or a Subsidiary, as appropriate, shall have
the right to deduct from all Awards paid in cash any federal, state or local
taxes as required by law to be withheld with respect to such cash payments,
and, in the case of Awards paid in Stock, the Employee or other person
receiving such Stock may be required to pay to the Company or a Subsidiary, as
appropriate, the amount of any such taxes which the Company or Subsidiary is
required to withhold with respect to such Stock. The Company may, in lieu of
requiring cash payment of any such taxes, elect to withhold from Stock
payments a number of whole shares of Stock whose value is at least equal to
the amount of such taxes. Valuation for this purpose shall be the average of
the reported high and low prices of the Stock as reported in the New York
Stock Exchange Composite Transactions quotations for the first trading date
following the Restriction Period, unless the Committee determines that it is
appropriate to value the Stock on some other date for this purpose.

  c. Claim to Awards and Employment Rights. No Employee or other person shall
have any claim or right to be granted an Award under the Plan. Neither this
Plan nor any action taken hereunder shall be construed as giving any Employee
any right to be retained in the employ of the Company or a Subsidiary.

  d. Beneficiaries. Any payment of Awards due under this Plan to a deceased
Holder shall be paid to the beneficiary designated by the Holder and filed
with the Company. If no such beneficiary has been designated, payment shall be
made to the Holder's surviving spouse. If the Holder has not designated a
beneficiary and has no surviving spouse, payment shall be made to the Holder's
legal representative. A beneficiary designation may be changed or revoked by a
Holder at any time, provided the change or revocation is filed with the
Committee.

  e. Nontransferability. A Holder's rights and interests under the Plan,
including amounts payable, may not be assigned, pledged, or transferred
except, in the event of an Employee's death, to a designated beneficiary as
provided in the Plan, or in the absence of such designation, by will or the
laws of descent and distribution, except as may be permitted by the Committee
in its sole discretion. The Committee, in its sole discretion, may permit
transfers of Options, Performance Shares and/or Restricted Stock Awards to an
Employee's family members and entities (including trusts, corporations,
partnerships, and limited liability companies) which are established for the
exclusive benefit of or are owned solely by family members and may prescribe
such rules and limitations as it deems appropriate regarding such transfers,
taking into account tax considerations, the impact of Section 16 of the
Securities Exchange Act of 1934, the need to register shares under the
Securities Act of 1933 and any applicable State Blue Sky Laws, and any other
relevant considerations.

  f. Indemnification. Each person who is or shall have been a member of the
Committee or the Board, including the Employee directors, shall be indemnified
and held harmless by the Company against and from any loss, cost, liability,
or expense that may be imposed upon or reasonably incurred by him in
connection with or resulting from any claim, action, suit, or proceeding to
which he may be a party or in which he may be involved by reason of any action
or failure to act under the Plan and against and from any and all amounts paid
by him in satisfaction of judgment in any such action, suit or proceeding
against him. He shall give the Company an opportunity, at its own expense, to
handle

                                     B-15
<PAGE>

and defend the same before he undertakes to handle and defend it on his own
behalf. The foregoing right of indemnification shall not be exclusive of any
other rights of indemnification to which such persons may be entitled under
the Company's Certificate of Incorporation or Bylaws, as a matter of law, or
otherwise, or any power that the Company may have to indemnify them or hold
them harmless.

  g. Reliance on Reports. Each member of the Committee and the Board,
including the Employee directors, shall be fully justified in relying or
acting in good faith upon any report made by the independent public
accountants of the Company and its Subsidiaries and upon any other information
furnished in connection with the Plan by any person or persons other than
himself. In no event shall any person who is or shall have been a member of
the Committee or of the Board be liable for any determination made or other
action taken or any omission to act in reliance upon any such report or
information or for any action taken, including the furnishing of information,
or failure to act, if in good faith.

  h. Relationship to Other Benefits. No payment under the Plan shall be taken
into account in determining any benefits under a pension, retirement, profit
sharing, group insurance or other benefit plan of the Company or any
Subsidiary.

  i. Expenses. The expenses of administering the Plan shall be borne by the
Company and its Subsidiaries.

  j. Pronouns. Masculine pronouns and other words of masculine gender shall
refer to both men and women.

  k. Titles and Headings. The titles and headings of the sections in the Plan
are for convenience of reference only, and in the event of any conflict, the
text of the Plan, rather than such titles or headings, shall control.

12. Changes in Capital Structure

  Options, Restricted Stock Awards, Performance Share Awards, Performance
Bonus Awards and any agreements evidencing such Awards shall be subject to
adjustment by the Committee as to the number and price of shares of Stock or
other considerations subject to such Awards in the event of changes in the
outstanding Stock by reason of stock dividends, stock splits,
recapitalizations, reorganizations, mergers, consolidations, combinations,
exchanges, or other relevant changes in capitalization occurring after the
Date of Grant of any such Options or Awards. In the event of any such change
in the outstanding Stock, the aggregate number of shares available under the
Plan and Program may be appropriately adjusted by the Committee, whose
determination shall be conclusive.

13. Amendments and Termination

  The Board may at any time terminate the Plan and, with the express written
consent of a Holder, the Board or Committee may cancel, reduce or otherwise
alter his outstanding Awards thereunder if, in its judgment, the tax,
accounting, or other effects of the Plan or potential payouts thereunder would
not be in the best interest of the Company. The Board may, at any time, or
from time to time, amend or suspend and, if suspended, reinstate, the Plan in
whole or in part, provided, however, that without further stockholder approval
the Board shall not:

  a. Increase the maximum number of shares which may be issued under the Plan
or Program, or the maximum number of shares which may be granted as Restricted
Stock Awards under the Plan or Program, except as provided in Section 12 or
increase the maximum cash bonus payable under a Performance Bonus Award under
the Plan;

  b. Change the minimum option price for Options; or

  c. Extend the termination date of the Plan.

   Rights: Shares Subject to the Plan

  The Committee may, from time to time, grant and amend Awards to eligible
Employees in accordance with the provisions of the Plan; provided, however,
that:

  a. Subject to Section 11, the aggregate number of shares of Stock made
subject to Awards under this Plan may not exceed 3,500,000 shares.

  b. To the extent an Award lapses or the rights of its Holder terminate or
are forfeited, any shares of Stock subject to such Award which are not
exercised or are forfeited shall again be available to be granted as an Award;
provided, however, that any shares of Stock which are subject to Options which
terminate due to failure to satisfy the Performance Conditions established for
exercise of the Options shall not be available to be the subject of another
Award. Upon the full or partial payment of any option price by the transfer to
the Company of Stock or upon satisfaction of tax withholding obligations in
connection with any such exercise or any other payment made or benefit

6. Eligibility

  Senior management and other key Employees of the Company and its
Subsidiaries (including officers or Employees who are members of the Board)

7. Performance Stock Options

  One or more Performance Stock Options may be granted to any eligible
Employee. No person may be granted during any 36-month period Performance
Stock Options to acquire more than 750,000 shares of Stock under this Plan.
Each Performance Stock Option so granted shall be subject to the following
conditions:

  a. Option Price. The option price per share of Stock for a Performance Stock
Option shall be set by the grant, but shall represent a premium of at least
25% over the Fair Market Value on the Date of Grant, as determined by the
Committee in its sole discretion.

  b. Form of Payment. At the time of the exercise of the Option, the option
price shall be payable in a combination of cash and/or shares of Stock
acceptable to the Committee valued at the Fair Market Value as of the date the
Option is exercised, including (if permitted by the Company) proceeds from the
sale of Stock acquired by exercise of the Option (a cashless exercise).

  c. Performance Conditions and Performance Period. The Committee shall
establish the Performance Conditions and Performance Period for each Option
granted under this Plan. The Performance Conditions may be based on increases
in the Fair Market Value of the Company's Stock and/or Comparative Return to
Stockholders during the Performance Period. A Performance Condition
established for the Option must be satisfied during the Performance Period in
order for the Holder to become entitled to exercise all or any portion of the
Option. Otherwise, the Option shall terminate and be forfeited at the end of

<PAGE>

  d. Vesting Conditions. The Committee shall impose Vesting Conditions for
each Option which must be satisfied in order for the Holder to become entitled
to exercise all or any portion of the Option. Unless the Committee provides
otherwise, the Vesting Condition for an Option will be satisfied if the Holder
remains in employment with the Company or a Subsidiary from the Date of Grant
until the end of the Performance Period for the Option, and in the event the
Holder terminates employment during the Performance Period, the Option will be
subject to the following:

    (i) Termination determined by the Committee to be at the convenience of
  the Company and not for "cause" or for performance inadequacy:

    --The Vesting Condition would be satisfied for a portion of the shares
      subject to the Option prorated for service during the Performance
      Period, and the balance of the shares subject to the Option would be
      forfeited.

    (ii) Resignation or discharge other than pursuant to Section 7(d)(i):

    --The Option would be completely forfeited.

    (iii) Retirement, other than early retirement, pursuant to the Company
  retirement plan then in effect:

    --The Vesting Condition would be satisfied for a portion of the shares
      subject to the Option prorated for service during the Performance
      Period, and the balance of the shares subject to the Option would be
      forfeited.

    (iv) Early Retirement:

    --If at the Holder's request, the Option would be completely forfeited.

    --If at the Company's request, the Vesting Condition would be satisfied
      for a portion of the shares subject to the Option prorated for
      service during the Performance Period, and the balance of the shares
      subject to the Option would be forfeited.

    (v) Death or Total and Permanent Disability:

    --The Vesting Condition would be satisfied for a portion of the shares
      subject to the Option prorated for service during the Performance
      Period, and the balance of the shares subject to the Option would be
      forfeited.

  e. Grant Agreement. Each Performance Stock Option granted under the Plan
shall be evidenced by a Grant Agreement between the Company and the Holder of
the Option containing provisions determined by the Committee, which shall
include the following terms and conditions:

    (i) Any Option or portion thereof that is exercisable shall be
  exercisable for the full amount or for any part thereof, except as
  otherwise determined by the grant.

    (ii) Every share purchased through the exercise of an Option shall be
  paid for in full prior to delivery of stock or, if permitted by the
  Company, through a cashless exercise. Each Option shall cease to be
  exercisable, as to any share, when the Holder purchases the share or when
  the Option lapses.

    (iii) Options shall not be transferable by the Holder except by will or
  the laws of descent and distribution and shall be exercisable during the
  Holder's lifetime only by the Holder, his guardian or legal representative,
  except as permitted pursuant to Section 10(e).

    (iv) In consideration for the granting of each Option, the Holder shall
  agree to remain in the employment of the Company or one or more of its
  Subsidiaries at the pleasure of the Company or such Subsidiary for a
  continuous period of at least one year after the Date of Grant. At the
  discretion of the Committee, this requirement may be waived if the Holder
  during said one-year period becomes incapacitated or enters the active
  service of the military forces of the United

                                     B-20
<PAGE>

  States or other United States service connected with national defense
  activities. The Holder agrees that during such employment, he will devote
  his entire time, energy and skills to the service and interest of the
  Company or such Subsidiary subject to vacations, sick leave, and other
  absences in accordance with the regular policies of the Company and its
  Subsidiaries.

    (v) Notwithstanding any other provision of the Plan, in the event of a
  public tender for all or any portion of the Stock of the Company; in the
  event that a proposal to merge, consolidate, or otherwise combine with
  another company is submitted for stockholder approval; or another situation
  exists which the Committee determines is similar thereto, the Committee may
  in its sole discretion declare outstanding Options for which the
  Performance Conditions have been or are thereafter satisfied to be
  immediately exercisable, and it may also include provisions for such events
  in the Grant Agreement. Any such event which causes an outstanding Option
  to be immediately exercisable shall be referred to in the Plan as a "Change
  in Control Event" and shall be deemed to satisfy the Vesting Conditions for
  the Option (except for any portion of the shares originally subject to the
  Option which have previously been forfeited).

    (vi) All Options granted under this Plan shall automatically terminate to
  the extent not previously exercised upon (i) a dissolution of the Company,
  (ii) a merger, reorganization, consolidation or similar event that the
  Company does not survive, or (iii) the consummation of a merger,
  reorganization, consolidation or similar event approved by the Board which
  the Board determines to be a Change in Control Event. The date upon which
  any such event occurs shall be referred to in the Plan as a "Conversion
  Date."

  f. Other Terms and Conditions. Each Option shall become exercisable in such
manner on or after such date or dates and within such period or periods, not
to exceed ten years from its Date of Grant, as set forth in the Grant
Agreement. An Option shall not become exercisable until the Performance
Conditions and Vesting Conditions for the Option have been satisfied, and,
unless the Grant Agreement provides otherwise, may not be exercised before the
end of the Performance Period for the Option. Unless the Grant Agreement
provides otherwise, an Option which is exercisable following termination of
employment shall remain exercisable until the end of the original term of the
Option.

8. Tandem Limited Stock Appreciation Rights

  The Committee has the power and sole discretion to grant Tandem Limited
Stock Appreciation Rights ("TLSARs") to eligible Employees in conjunction with
Options granted under the Plan. Each TLSAR so granted shall be subject to the
following conditions:

  a. Grant of TLSAR: Grant Price and Number of Shares. The grant price and
number of shares of Stock subject to a TLSAR granted in conjunction with an
Option shall be set forth in the Grant Agreement for the Award. The grant
price per share of Stock for a TLSAR shall not be less than the Fair Market
Value on the Date of Grant.

  b. Termination Date of TLSAR. A TLSAR shall terminate on the earlier of the
following dates:

    (i) The date on which the related Option is exercised, with respect to
  the same percent of shares of Stock subject to the TLSAR as the percent of
  shares of Stock subject to the related Option which were exercised.

    (ii) The date on which the related Option lapses or is terminated or
  forfeited, unless the TLSAR is payable on such date.

  In the event of the termination of employment of a Holder, a TLSAR shall be
forfeited with respect to the same percent of shares of Stock subject to the
TLSAR as the percent of shares of Stock subject to the related Option which
were forfeited on account of such termination of employment.

                                     B-21
<PAGE>

  c. Timing and Form of Payment for TLSAR. Each TLSAR which has not otherwise
terminated or been forfeited shall become immediately vested and payable upon
the occurrence of a Conversion Date. The Holder shall be entitled to receive
payment from the Company equal to the amount determined by multiplying (i)
times (ii):

    (i) The amount by which the Fair Market Value of a share of Stock on or
  immediately prior to the Conversion Date exceeds the grant price of the
  TLSAR.

    (ii) The number of shares of Stock with respect to which the TLSAR is
  payable.

  Each TLSAR shall be paid in cash, provided that if any such payment would
cause a Change in Control Event to be ineligible for pooling of interests
accounting under APB No. 16, which transaction but for such payment otherwise
would have been eligible to receive such accounting treatment, any TLSAR shall
be paid in shares of Stock having a Fair Market Value equal to the cash amount
foregone.

  d. Grant Agreement. Each Tandem Limited Stock Appreciation Right granted
under the Plan in conjunction with an Option shall be evidenced by the Grant
Agreement between the Company and the Holder of the Option and TLSAR
containing provisions determined by the Committee. The Grant Agreement shall
provide that TLSARs shall not be transferable by the Holder except by will or
the laws of descent and distribution and shall be payable during the Holder's
lifetime only to the Holder, his guardian or legal representative, except as
permitted pursuant to Section 10(e).

9. Initial Awards of Performance Stock Options and Tandem Limited Stock
   Appreciation Rights

  The Initial Awards under the Plan were granted by the Committee, subject to
approval of the Plan by the Company's stockholders in compliance with the
requirements of the New York Stock Exchange, on March 30, 1998, which shall be
the Date of Grant for the Initial Awards. The Initial Awards of Performance
Stock Options and Tandem Limited Stock Appreciation Rights shall be subject to
the following conditions:

  a. Option Price for Performance Stock Options. The option price per share of
Stock for Initial Awards of Options shall be the greater of:

    (i) $50.00, or

    (ii) a price 33 1/3% above the Average Fair Market Value of the Stock
  during the period from January 26, 1998 to May 29, 1998, including such
  beginning and ending dates.

  b. Performance Period. The Performance Period for Initial Awards of Options
shall be the period of time beginning on the Date of Grant and ending on the
third anniversary of the Date of Grant for such Options.

  c. Performance Conditions. The Performance Conditions for Initial Awards of
Options will be satisfied if the Company's Stock achieves either (i) a certain
Stock price or (ii) a certain Comparative Return to Stockholders, as each is
specified below, during the Performance Period:

    (i) Stock Price. The Fair Market Value of the Stock has been equal to or
  greater than the option price for ten trading days (occurring within any
  period of twenty consecutive trading days) during the Performance Period.

    (ii) Comparative Return to Stockholders. The Comparative Return to
  Stockholders places the Company in the top quartile (75th percentile or
  above) of the Peer Group Companies for the Performance Period, as
  determined by the Committee.

                                     B-22
<PAGE>

  d. Vesting Conditions. The Vesting Conditions for Options set forth in
Section 7(d) shall apply to Initial Awards of Options.

  e. Exercise Period. If the Performance Condition is satisfied, vested
Options under Initial Awards may be exercised from the first day after the end
of the Performance Period through the tenth anniversary of the Date of Grant
of such Initial Awards.

  f. Change in Control Event. Upon the occurrence of a Change in Control
Event, the Vesting Conditions of Options under Initial Awards shall be waived,
and, if the Performance Condition has been satisfied, such Options may be
immediately exercised. If the Performance Conditions have not yet been
satisfied, such Options may be exercised immediately upon satisfaction of the
Performance Conditions. For Initial Awards, a Change in Control Event shall
include the following:

    (i) Approval by the stockholders of the Company of the dissolution or
  liquidation of the Company;

    (ii) Approval by the stockholders of the Company of an agreement to merge
  or consolidate, or otherwise reorganize, with one or more entities that are
  not Subsidiaries or other controlled affiliates, as a result of which less
  than 50% of the outstanding voting securities of the surviving or resulting
  entity immediately after the reorganization are, or will be, owned,
  directly or indirectly, by stockholders of the Company immediately before
  such reorganization (assuming for purposes of such determination that there
  is no change in the record ownership of the Company's securities from the
  record date for such approval until such reorganization and that such
  record owners hold no securities of the other parties to such
  reorganization, but including in such determination any securities of the
  other parties to such reorganization held by Subsidiaries or other
  controlled affiliates of the Company);

    (iii) Approval by the stockholders of the Company of the sale of
  substantially all of the Company's business and/or assets to a person or
  entity that is not a Subsidiary or other controlled affiliate;

    (iv) Any "person" (as such term is used in Sections 13(d) and 14(d) of
  the Securities Exchange Act of 1934, as amended (the "Exchange Act"), but
  excluding any person described in and satisfying the conditions of Rule
  13d-1(b)(1) thereunder), other than a Subsidiary or other controlled
  affiliate and other than an employee benefit plan sponsored by the Company
  or any of its Subsidiaries or controlled affiliates, becomes the beneficial
  owner (as defined in Rule 13d-3 under the Exchange Act, and except pursuant
  to customary forms of revocable proxies used in connection with annual
  meetings of stockholders), directly or indirectly, of securities of the
  Company representing more than 50% of the combined voting power of the
  Company's then outstanding securities entitled to then vote generally in
  the election of directors of the Company; or

    (v) During any period not longer than two consecutive years, individuals
  who at the beginning of such period constituted the Board of Directors
  cease to constitute at least a majority thereof, unless the election, or
  the nomination for election by the Company's stockholders, of each new
  Board member was approved by a vote of at least three-fourths of the Board
  members then still in office who were Board members at the beginning of
  such period (including for these purposes, new members whose election or
  nomination was so approved).

For purposes of clause (iv) above, a person shall be deemed to have the right
to acquire outstanding securities immediately prior to the actual acquisition
of the securities if the securities are acquired pursuant to a tender or
exchange offer subject to Section 14(d) of the Exchange Act.

  g. TLSARs. TLSARs shall be granted in tandem with Options pursuant to
Initial Awards and shall be subject to the terms and conditions of Section 8
of the Plan. The grant price and number of

                                     B-23
<PAGE>

shares of Stock subject to TLSARs granted pursuant to Initial Awards shall be
set forth in the Grant Agreement. TLSARs will be granted for a number of
shares of Stock equal to (i) 0.53 times (ii) the number of shares of Stock
under the related Performance Stock Option. The grant price per share of Stock
for the TLSARs will be the greater of (i) $38.6875 or (ii) the Fair Market
Value on the Date of Grant.

  h. Grant Agreement. The Grant Agreements for Initial Awards shall contain
such provisions as the Committee may determine, which shall include the terms
and conditions set forth in Sections 7(e) and 8(d) of the Plan.

10. General

  a. Government and Other Regulations. The obligation of the Company to make
payment of Awards in Stock or otherwise shall be subject to all applicable
laws, rules, and regulations, and to such approvals by governmental agencies
as may be required. The Company shall be under no obligation to register under
the Securities Act of 1933, as amended ("Act") any of the shares of Stock paid
under the Plan. If the Stock issued under the Plan may in certain
circumstances be exempt from registration under the Act, the Company may
restrict the transfer of such shares in such manner as it deems advisable to
ensure the availability of any such exemption.

  b. Tax Withholding. The Company or a Subsidiary, as appropriate, shall have
the right to deduct from all Awards paid in cash any federal, state or local
taxes as required by law to be withheld with respect to such cash payments,
and, in the case of Awards paid in Stock, the Employee or other person
receiving such Stock may be required to pay to the Company or a Subsidiary, as
appropriate, the amount of any such taxes which the Company or Subsidiary is
required to withhold with respect to such Stock. The Company may, in lieu of
requiring cash payment of any such taxes, elect to withhold from Stock
payments a number of whole shares of Stock whose value is at least equal to
the amount of such taxes. Valuation for this purpose shall be the average of
the reported high and low prices of the Stock as reported in the New York
Stock Exchange Composite Transactions quotations for the applicable date as
determined by the Committee.

  c. Claim to Awards and Employment Rights. No Employee or other person shall
have any claim or right to be granted an Award under the Plan. Neither this
Plan nor any action taken hereunder shall be construed as giving any Employee
any right to be retained in the employ of the Company or a Subsidiary.

  d. Beneficiaries. Any payment of Awards due under this Plan to a deceased
Holder shall be paid to the beneficiary designated by the Holder and filed
with the Committee. If no such beneficiary has been designated, payment shall
be made to the Holder's surviving spouse. If the Holder has not designated a
beneficiary and has no surviving spouse, payment shall be made to the Holder's
legal representative. A beneficiary designation may be changed or revoked by a
Holder at any time, provided the change or revocation is filed with the
Committee.

  e. Nontransferability. A Holder's rights and interests under the Plan,
including amounts payable, may not be assigned, pledged, or transferred
except, in the event of an Employee's death, to a designated beneficiary as
provided in the Plan, or in the absence of such designation, by will or the
laws of descent and distribution, except as may be permitted by the Committee
in its sole discretion. The Committee, in its sole discretion, may permit
transfers of Options and/or TLSARs to an Employee's family members and
entities (including trusts, corporations, partnerships, and limited liability
companies) which are established for the exclusive benefit of or are owned
solely by family members and may prescribe such rules and limitations as it
deems appropriate regarding such transfers, taking into account tax
considerations, the impact of Section 16 of the Securities Exchange Act of
1934, the need to register shares under the Securities Act of 1933 and any
applicable State Blue Sky Laws, and any other relevant considerations.

                                     B-24
<PAGE>

  f. Indemnification. Each person who is or shall have been a member of the
Committee or the Board, including the Employee directors, shall be indemnified
and held harmless by the Company against and from any loss, cost, liability,
or expense that may be imposed upon or reasonably incurred by him in
connection with or resulting from any claim, action, suit, or proceeding to
which he may be a party or in which he may be involved by reason of any action
or failure to act under the Plan and against and from any and all amounts paid
by him in satisfaction of judgment in any such action, suit or proceeding
against him. He shall give the Company an opportunity, at its own expense, to
handle and defend the same before he undertakes to handle and defend it on his
own behalf. The foregoing right of indemnification shall not be exclusive of
any other rights of indemnification to which such persons may be entitled
under the Company's Certificate of Incorporation or Bylaws, as a matter of
law, or otherwise, or any power that the Company may have to indemnify them or
hold them harmless.

  g. Reliance on Reports. Each member of the Committee and the Board,
including the Employee directors, shall be fully justified in relying or
acting in good faith upon any report made by the independent public
accountants of the Company and its Subsidiaries and upon any other information
furnished in connection with the Plan by any person or persons other than
himself. In no event shall any person who is or shall have been a member of
the Committee or of the Board be liable for any determination made or other
action taken or any omission to act in reliance upon any such report or
information or for any action taken, including the furnishing of information,
or failure to act, if in good faith.

  h. Relationship to Other Benefits. No payment under the Plan shall be taken
into account in determining any benefits under a pension, retirement, profit
sharing, group insurance or other benefit plan of the Company or any
Subsidiary.

  i. Expenses. The expenses of administering the Plan shall be borne by the
Company and its Subsidiaries.

  j. Pronouns. Masculine pronouns and other words of masculine gender shall
refer to both men and women.

  k. Titles and Headings. The titles and headings of the sections in the Plan
are for convenience of reference only, and in the event of any conflict, the
text of the Plan, rather than such titles or headings, shall control.

11. Changes in Capital Structure

  Options, TLSARs and any agreements evidencing such Awards shall be subject
to adjustment by the Committee as to the number and price of shares of Stock
or other considerations subject to such Awards in the event of changes in the
outstanding Stock by reason of stock dividends, stock splits,
recapitalizations, reorganizations, mergers, consolidations, combinations,
exchanges, or other relevant changes in capitalization occurring after the
Date of Grant of any such Options or Awards. In the event of any such change
in the outstanding Stock, the aggregate number of shares available under the
Plan may be appropriately adjusted by the Committee, whose determination shall
be conclusive.

                                     B-25
<PAGE>

12. Amendments and Termination

  The Board may at any time terminate the Plan and, with the express written
consent of a Holder, the Board or Committee may cancel, reduce or otherwise
alter his outstanding Awards thereunder if, in its judgment, the tax,
accounting, or other effects of the Plan or potential payouts thereunder would
not be in the best interest of the Company. The Board may, at any time, or
from time to time, amend or suspend and, if suspended, reinstate, the Plan in
whole or in part, provided, however, that without further stockholder approval
the Board shall not:

  a. Increase the maximum number of shares which may be issued under the Plan,
except as provided in Section 11;

  b. Change the minimum option price for Options or minimum grant price for
TLSARs; or

  c. Extend the termination date of the Plan.
