                                 PROPOSAL NO. 1
 
                             ELECTION OF DIRECTORS
 
     As of January 18, 1996, the Board of Directors will consist of 14 members.
The Board is divided into three Classes (A, B, and C) consisting of 5, 4, and 5
members respectively. Each Class is elected for a term of three years, with the
term of one class expiring at each annual meeting of shareholders.
 
     The By-laws of the Corporation provide that a person shall not be elected
or reelected to the Board of Directors after the person's 70th birthday. At the
request of the Board, the Nominating Committee reviewed the present structure
and composition of the Board; and as a result of the review, the Board was
advised that there is an uneven distribution of age groups among the Board
Classes and, as currently structured, one-half of the members of the Board would
retire during the next seven-year period, assuming future reelections by the
shareholders of the current directors in their present Classes.
 
     The Committee, therefore, recommended and the Board of Directors approved a
voluntary plan to move certain of the Directors from one class to another, with
the concurrence of the affected Directors. The purpose of the plan is to secure
for the Corporation the maximum benefits from the knowledge, experience, and
expertise of the current members of the Board and to facilitate an orderly
transition of membership on the Board. If the changes are made, the affected
Directors would each be eligible to serve approximately two
 
                                        4
<PAGE>   7
 
additional years on the Board. However, in order to carry out this plan it would
be necessary for four members of the Board to resign from their present Classes
so they could be elected to other Classes.
 
     Although under the By-laws the Board could have filled the positions
created by voluntary Director resignations in the two Classes (A and B) whose
terms expire after 1996, the Board has instead decided to submit to the

                 BOARD EXECUTIVE COMPENSATION COMMITTEE REPORT
                           ON EXECUTIVE COMPENSATION
 
     The Executive Compensation Committee (the Committee) is responsible for
overseeing and approving the Corporation's executive compensation policies and
practices and approves all elements of compensation for corporate officers. In
carrying out its duties, the Committee has direct access to independent
compensation consultants and outside survey data. The Committee, which consists
of five outside directors, reports regularly to the Board of Directors on its
activities and obtains ratification by the members of the Board of all items of
compensation for the officers of the Corporation, its divisions, and its
subsidiary corporations.
 
COMPENSATION PHILOSOPHY AND PRACTICES
 
     The Corporation's executive compensation program is based on the belief
that the interests of executives should be closely aligned with those of ONEOK
shareholders. To support this philosophy, the following principles provide a
framework for the compensation program:
 
- -- offer compensation opportunities that attract the best talent to ONEOK;
   motivate individuals to perform at their highest levels; reward outstanding
   achievement; and retain the leadership and skills necessary for building
   long-term shareholder value;
 
- -- maintain a significant portion of executives' total compensation at risk,
   tied to both the annual and long-term financial performance of the
   Corporation, as well as to the creation of shareholder value;
 
- -- encourage executives to manage from the perspective of owners with an equity
   stake in the Corporation.
 
     ONEOK established base salary ranges for its key executive officers that
were approximately equal to the average salary levels paid for similar positions
in its peer group of companies as obtained through published surveys and company
documents. Diversity of executive assignments requires that individual salaries
be based on periodic comparison of actual pay for comparable positions in the
utility and oil and gas segments of the energy industry.
 
     The executive compensation practices are recommended by independent
consultants using industry salary surveys that include the American Gas
Association Executive Compensation Survey, the KPMG Oil and Gas Industry
Compensation Survey, the Mercer Oil and Gas Industry Compensation Survey, the
Towers & Perrin Natural Gas Pipeline Survey, and the Watson Wyatt Worldwide
Compensation Survey. These surveys include corporations that are representative
of the firms with which ONEOK competes for executive talent and have jobs
similar to those at ONEOK in magnitude, complexity, and scope of responsibility.
Consequently, this is a broader and more diverse set of companies than those
included in the Standard & Poor's Natural Gas Distribution Index, which is used
in the Performance Graph on page 13.
 
COMPONENTS OF EXECUTIVE COMPENSATION
 
     The compensation for executive officers consists of the following
components. An executive's annual compensation includes the core package
component of base salary and benefits and the variable component, which is
entirely at risk. The variable component is tied to specific earnings-per-share
performance measures relating to the continued financial success of the
Corporation. Salaries are established by the Committee based on the executive's
job responsibilities, level of experience, individual performance and
contribution to the business, and information obtained from compensation
surveys. Criteria on which individual performance was evaluated in 1995 were:
problem analysis; planning; organizational ability; directing; decision making;
human, capital, and material resource utilization; time management; initiation
of and response to change; communications and team relations; and personal
actions.
 
     The Stock Performance Plan (the Plan), a five-year plan, approved by the
shareholders, that became effective September 1, 1991, and which will remain in
effect until August 31, 1996, or its earlier termination, followed a similar
plan, also approved by the shareholders, that was in effect from September 1986
through August 1991. The Committee provides oversight of the Plan and is
authorized to make all judgments and interpretations required to execute the
Plan in accordance with its stated purposes subject to ratification by the
 
                                       11
<PAGE>   14
 
Board of Directors. Participation in the Plan is restricted to officers of ONEOK
Inc. and its divisions and wholly owned subsidiaries who are recommended for
Target Grants by the Executive Compensation Committee at the beginning of each
fiscal year.
 
     A Target Grant is a tentative dollar amount of additional compensation
which could be paid in ONEOK Inc. Common Stock to an eligible officer who has
been selected for participation during the fiscal year. Based on the percentage
of increase in ONEOK Inc.'s after-tax earnings per share, Target Grants are
multiplied by specified factors to determine the amounts of the actual Grants.
Target Grants become actual Grants of additional compensation only if two tests
are met: (1) there must be an increase of at least four percent (4%) in ONEOK
Inc.'s after-tax earnings per share over the preceding fiscal year's earnings
per share; and (2) the current year's earnings per share must equal or exceed
earnings per share of $1.33 as provided in the current Plan. For increases in
earnings per share between four percent (4%) and twelve percent (12%), the
individual Grants range proportionately from fifty percent (50%) to a maximum of
125 percent (125%) of the individual Target Grant. The payments of individual
Grants are normally made in a combination of full shares of common stock and
cash to satisfy taxes incurred.
 
     Stock distribution and cash payments are made on a date set in accordance
with the terms of the Plan. The Committee has the discretion to decline
recommendations of awards under the Plan whether or not the earnings-per-share
criteria are met. In 1995 the Corporation's financial performance resulted in
above-target grants to the executive officers as shown in the Summary
Compensation Table on page 10. The Stock Performance Plan will expire August 31,
1996, as provided in the Plan, or upon shareholder approval of the Key Employee
Stock Plan at the January 18, 1996, Annual Meeting of Shareholders. The Key
Employee Stock Plan is printed as Exhibit B to this proxy statement.
 
COMPENSATION FOR THE CHIEF EXECUTIVE OFFICER
 
     In considering the annual compensation for Mr. Brummett, who, in addition
to his duties as Chief Executive Officer, is Chairman of the Board and
President, the Committee relied on the aforementioned surveys to provide basic
information regarding peer positions. The C. A. Turner Utility Report on
financial and stock performance and comparisons of American Gas Association
member companies' operating statistics are also utilized. The industry
statistics have large comparative universes of natural gas distribution and
integrated natural gas companies. The companies in the Standard & Poor's Natural
Gas Distributors' Index, which is part of the Performance Graph on page 13, are
included in the C. A. Turner Utility Report. The Committee also considered the
results of a formal Board of Directors' Evaluation of Mr. Brummett's performance
during the 1995 Fiscal Year, his first full year as Chairman of the Board,
President, and Chief Executive Officer of the Corporation. The categories in
which his performance was evaluated include: leadership, strategic planning,
human resources, and communication. Each of the categories evaluated contains as
many as five areas of specific performance evaluation. The Committee recommended
and the Board of Directors approved a base compensation amount of $350,000 and a
Target Grant under the Stock Performance Plan (the at-risk portion of his
compensation) of $286,370, which was forty-five percent (45%) of the recommended
total compensation. Because Mr. Brummett was paid at his previously approved
salary four months in the 1995 Fiscal Year, the actual salary he received in
fiscal 1995 was $335,000. Mr. Brummett's actual Grant under the Stock
Performance Plan was $357,963; thus fifty-two percent (52%) of his compensation
related to the Corporation's performance during the year. Mr. Brummett's base
salary was in the lower range of the surveys utilized in the studies.
 
FEDERAL INCOME TAX LIABILITY
 
     ONEOK Inc. has not yet adopted a policy regarding the recently enacted
Internal Revenue Code Section 162(m) regarding a $1 million annual limitation of
a Federal income tax deduction by the Corporation for compensation paid to any
executive officer. This limitation did not apply to ONEOK Inc. during fiscal
year 1995; however, the new Internal Revenue Code requirement is being evaluated
and the proposed tax regulations are being closely monitored.

CONCLUSION
 
     The Board believes that the caliber and motivation of ONEOK's leadership
are fundamentally important to achieving the Corporation's objectives
established by the strategic plan and providing a sound investment for the
shareholders. The Committee is responsible to the Board, and by extension to the
shareholders, for ensuring that executives are compensated in a way that is
compatible with ONEOK's business strategies, thereby aligning their interests
with those of long-term investors. We believe the current methodology governing
executive compensation standards will prove beneficial to the Corporation, its
shareholders, its customers, and the communities served.

                           THE STOCK PERFORMANCE PLAN
 
     The Executive Compensation Committee implemented, and the Board of
Directors approved, a five-year Stock Performance Plan (Plan) effective
September 1, 1991, that will terminate August 31, 1996, or upon shareholder
approval of the Key Employee Stock Plan (see page 20), which is being submitted
to the shareholders at the January 18, 1996, Annual Meeting of Shareholders. The
current Plan followed a similar Plan that had been in effect from September 1,
1986, through August 31, 1991. The Stock Performance Plan is administered by the
Executive Compensation Committee of the ONEOK Inc. Board of Directors. This
committee is authorized to make all judgments and interpretations required to
execute the Plan in accordance with its stated purpose, subject to ratification
by the Board of Directors. Participation in the Plan is restricted to officers
of ONEOK Inc. and its divisions and wholly owned subsidiaries who are
recommended for Target Grants by the Executive Compensation Committee at the
beginning of each fiscal year. The Plan is designed to encourage increased
shareholder value while strengthening corporate objectives through increased
stock ownership by all officers. A Target Grant is a tentative dollar amount of
additional compensation which could be paid to an eligible officer who has been
selected for participation during the fiscal year. Based on the percentage of
increase in ONEOK Inc.'s after-tax earnings per share during each current fiscal
year, the Target Grants are multiplied by applicable factors to determine the
amounts of the actual Grants. Target Grants become actual Grants of additional
compensation only if two tests are met: (1) there must be an increase of at
least four percent (4%) in ONEOK Inc.'s after-tax earnings per share over the
preceding fiscal year's earnings per share and (2) the current year's earnings
per share must equal or exceed $1.33, as provided in the current Plan. For
increases in earnings per share between four percent (4%) and twelve percent
(12%), the individual Grants range proportionately from fifty percent (50%) to
one hundred twenty-five percent (125%) of the individual Target Grant. The
Grants are not increased for earnings increases over twelve percent (12%). The
payments of individual Grants are normally made in a combination of full shares
of stock and cash. Stock distribution and cash payments are made on a date set
in accordance with the terms of the Plan.
 
     The Executive Compensation Committee has the discretion to decline or
reduce recommendations of awards under the Plan whether or not the
earnings-per-share criteria are met.
 
     The Plan will be terminated effective January 18, 1996, assuming
shareholder approval of the Key Employee Stock Plan, and no further awards will
be made under this Plan.
 
     The following Target Grants for the indicated officers were established by
the Board of Directors August 18, 1994, for the 1995 Fiscal Year.

(1) For purposes of the above table, the annual Social Security Covered
    Compensation benefit ($25,920) was used in the excess benefit calculation.
 
(2) For persons who retired through 1995, the Internal Revenue Code limits
    annual payments from the Retirement Plan to $120,000, with lesser amounts
    under certain circumstances. Such limits are now adjusted for changes in the
    cost of living. For employees eligible under the Supplemental Executive
    Retirement Plan, the remaining amounts of annual benefit payments will be
    paid pursuant to that Plan.
 
(3) For plan years beginning after December 31, 1993, as a result of the Omnibus
    Budget Reconciliation Act of 1993, the annual compensation of each employee
    which is to be taken into account under the Retirement Plan cannot exceed
    $150,000 (adjusted for increases in the cost of living).
 
(4) These amounts are estimates only and would be subject to adjustment based on
    rules and regulations applicable to the method of distribution and survivor
    benefit options selected by the retiree. Retirement benefits would be
    actuarially reduced for retirement prior to age 65.
 
(5) The compensation covered by the Retirement Plan benefit formula is the basic
    salary paid to an employee within the employee's final average earnings. The
    final average earnings means the employee's highest earnings during any
    sixty consecutive months during the entire period of employment. For any
    employee named or shown in the Summary Compensation Table who retires with
    vested benefits under the Plan, the compensation shown as "salary" in the
    Summary Compensation Table could be considered covered compensation in
    determining benefits, except that the Plan benefit formula takes into
    account only a fixed percentage of final average earnings which is uniformly
    applied to all employees. The amount of covered compensation that may be
    considered in calculating retirement benefits is also subject to limitations
    in the Internal Revenue Code applicable to the Plan.
 
     The RETIREMENT PLAN FOR EMPLOYEES OF ONEOK INC. AND SUBSIDIARIES (PLAN) is
a tax-qualified, defined-benefit pension plan under the Internal Revenue Code
and the Employee Retirement Income Security Act of 1974. In Plan years prior to
1989, benefits became vested and nonforfeitable after completion of ten years of
continuous employment; and in Plan years after 1988, benefits become vested and
nonforfeitable after completion of five years of continuous employment. A vested
participant receives the retirement benefit upon attaining retirement age under
the Retirement Plan notwithstanding an earlier separation from service. Benefits
(joint and survivor for married participants unless they otherwise elect) are
calculated at retirement date based on credited service, limited to a maximum of
35 years, and final average earnings; and monthly benefits are distributed by an
insurance company. At August 31, 1995, the executive officers named in the
Summary Compensation Table had the following credited service under the Plan,
respectively: Larry W. Brummett, 20 years and 2 months; David L. Kyle, 20 years
and 2 months; Bill M. Van Meter, 9 years and 7 months; Jerry D. Neal, 32 years
and 9 months; and Frank W. Schemm, 34 years and 2 months.

<PAGE>   19
 
     The maximum annual benefits for employees in higher salary classifications
retiring at age 65 with the specified years of service are as shown in the table
on page 16. There are a number of options available to a retiring employee such
as the method of distribution and survivor benefit options, which, when selected
by the retiree, could result in reduced monthly pension payments. Retirement
benefits also would be actuarially reduced for retirement prior to age 65.
 
     The SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN (SERP) covers elected officers
of the Corporation, appointed officers of the Corporation, and certain other
highly compensated employees in the management of the Corporation who are
selected for participation by the Executive Compensation Committee and approved
by the Board of Directors and who are also eligible to receive limited benefits
from the Retirement Plan for employees of ONEOK Inc. and Subsidiaries. An
administrative committee interprets and administers the SERP. The benefit
payable to an employee under the SERP is equal to the benefit which would be
payable to the employee under the Retirement Plan for Employees of ONEOK Inc.
and Subsidiaries if the limitations prescribed by Sections 401(a)(17) and 415 of
the Internal Revenue Code of 1986, as amended, were not applicable, less the
benefit payable under the Retirement Plan with such limitations. Benefits under
the SERP are paid coincidentally with the payment of benefits under the
Retirement Plan or as the administrative committee may determine. These benefits
are unfunded and are payable from the general assets of the Corporation. The
Board of Directors may amend or terminate the SERP at any time; however,
benefits accrued prior to termination of the SERP will not be affected.
 
                         TERMINATION OF EMPLOYMENT AND
                         CHANGE OF CONTROL ARRANGEMENTS
 
     On January 19, 1984, the Board of Directors adopted a Severance Pay Policy
(Policy) for all employees including officers of the Corporation, its divisions,
and its subsidiaries; and authorized Termination Agreements to be entered into
with officers of the Corporation, its divisions, and its subsidiaries.
 
     If within two years of any change of control, employment is terminated
either involuntarily or voluntarily following a material adverse change in
compensation, responsibility, and/or working conditions, under the Policy the
affected employee will receive severance pay equal to eight weeks' pay for each
full year of service. Change of control occurs when a person or group acquires
beneficial ownership of twenty percent (20%) or more of the voting power of the
Corporation; or if after a transaction--including a cash tender or exchange
offer, merger or other business combination, sale of assets, contested election,
or any combination thereof--the directors, prior to such transaction, cease to
constitute a majority of the Board of Directors of the Corporation or its
successor. The Policy applies to a change in control that might have occurred
within three years of its adoption January 20, 1984, and automatically extends
from year to year or until terminated by the Board at the end of any annual
period thereafter (Covered Period).
 
     Termination Agreements have been entered into with the officers of the
Corporation, its divisions, and subsidiaries. Upon change of control during the
Covered Period and termination of employment of an officer within three years
after such change of control, but prior to the officer's 65th birthday, the
officer would receive a lump-sum termination payment. The payment would equal
three times the respective officer's annual salary and bonus, if any, plus the
retirement and other employee benefits to which the officer would have been
entitled during the next three years had the officer's employment not been
terminated. No termination payment is required if the termination is due to the
officer's death, total or permanent disability, resignation without consent of
the Board of Directors, or other than for good reasons as defined in the
Termination Agreement.
 
     Assuming a change of control and termination of their employment on August
31, 1995, the Executive Officers named in the Summary Compensation Table, All
Current Executive Officers as a Group, and All Other Current Officers as a Group
would have been entitled to receive the following payments under the Policy and
their Termination Agreements, respectively: Larry W. Brummett, $1,082,335 and
$1,102,566; David L. Kyle, $775,404 and $817,566; Bill M. Van Meter, $402,164
and $877,291; Jerry D. Neal, $818,080 and $576,437; and Frank W. Schemm,
$673,632 and $456,965. All Current Executive Officers as a Group, $4,434,463 and
$4,250,625; and All Other Current Officers as a Group, $9,217,135 and
$7,681,515.

                                 PROPOSAL NO. 2
 
              PROPOSAL TO APPROVE THE EMPLOYEE STOCK PURCHASE PLAN
 
GENERAL INFORMATION
 
     The Board of Directors has adopted, subject to shareholder approval, the
ONEOK Inc. Employee Stock Purchase Plan ("Purchase Plan") pursuant to which a
total of 350,000 shares of ONEOK Inc. Common Stock, without par value ("Common
Stock") may be sold to eligible employees of the Corporation and its
subsidiaries at a discount from the market value of the shares. The Board of
Directors adopted the Purchase Plan because the Directors believe that it is
desirable to offer employees an inducement to acquire an ownership interest in
the Corporation on a tax-favored basis. The summary of the material features of
the Purchase Plan that follows is in all respects subject to and qualified by
reference to the actual text of the Purchase Plan, which appears in its entirety
as Exhibit A to this Proxy Statement.
 
THE PURCHASE PLAN
 
     The persons who are eligible to participate in the Purchase Plan are
employees of the Corporation and such of its subsidiaries as are designated by
the Compensation Committee as participating employers, including members of the
Board of Directors who are employees, whose customary employment is more than 20
hours per week and 5 months in a calendar year and who have at least one year of
service, or who meet such lesser customary employment and service requirements
as the Committee may specify on a uniform and non-discriminatory basis.
Employees who own five percent (5%) or more of the Corporation's stock or a
subsidiary's stock may not purchase stock under the Employee Stock Purchase
Plan.
 
     Under the Purchase Plan, the Committee may permit eligible employees to
purchase, through regular payroll deductions, shares of Common Stock at a
purchase price equal to the lesser of (a) eighty-five percent (85%) of the fair
market value of a share of Common Stock at the beginning of an offering period,
or (b) eighty-five percent (85%) of the fair market value of a share of Common
Stock at the end of such offering period. In its discretion, the Compensation
Committee, which will administer the Purchase Plan, may set a higher (but not a
lower) purchase price in advance of any offering period and may permit employee
contributions to be made by means in addition to payroll deductions (such as
lump sum payments). Under the Purchase Plan, the fair market value of a share of
Common Stock is generally equal to the average of the high and low sale prices
of a share of Common Stock in consolidated trading on the date in question as
reported by The Wall Street Journal or another reputable source designated by
the Committee.
 
     The duration of offering periods will be determined by the Compensation
Committee in its discretion and may not exceed twenty-seven (27) months. The
Compensation Committee will also determine the date on which each offering
period will begin. For example the Committee may, but need not, provide that two
or more offering periods of different durations will begin on the same date, or
that offering periods of uniform duration will commence at uniform (e.g.,
annual) intervals. However, the Purchase Plan provides that unless the
Compensation Committee determines otherwise, a new offering period will commence
in the first payroll period coinciding with or next following January 1 of each
year and will extend until the next offering commences. The Compensation
Committee may at any time suspend or accelerate the completion of an offering
period, including upon or in contemplation of a Change in Control. For a
description of the events that constitute a Change in Control, see "Proposal to
Approve The Key Employee Stock Plan" elsewhere in this Proxy Statement.
 
     An eligible employee may contribute up to a maximum of ten percent (10%) of
his/her base compensation (or such lesser amount as the Compensation Committee
may prescribe) for purchase of shares pursuant to the Purchase Plan. Payroll
deductions will be accumulated and, along with any other employee contributions
(e.g., lump sum contributions), will be used to purchase shares of Common Stock
at the end of the offering period. A participant may generally increase,
decrease, or suspend payroll deductions during an offering period or withdraw
from participation in the Purchase Plan at any time. If a participant's
employment terminates for any reason before the end of an offering period, his
or her participation in the Purchase Plan ceases immediately, and any
accumulated employee contributions are paid to such participant. No participant
 
                                       18
<PAGE>   21
 
may purchase more than $25,000 of Common Stock in any calendar year, measured by
its undiscounted value at the beginning of each offering or such lesser amount
as the Compensation Committee may fix under the Purchase Plan from time to time.
 
     The 350,000 shares of Common Stock that are authorized for sale under the
Purchase Plan may be authorized and unissued shares, treasury shares, or any
combination thereof. The Purchase Plan authorizes the Corporation to issue or
transfer sufficient shares of Common Stock to a trust (including a grantor
trust) at any time (including upon or in contemplation of a Change in Control)
to satisfy its obligations under any offerings then in progress, in which case
the shares may be treated as authorized and issued shares while held in the
trust with full dividend and voting rights.
 
     The Board of Directors may amend the Purchase Plan at any time and in any
respect without shareholder approval unless shareholder approval of the
amendment in question is required under Delaware law, the Internal Revenue Code
of 1986, as amended (Code), any applicable exemption from Section 16 of the
Securities Exchange Act of 1934, as amended, for which the Corporation intends
transactions by executive officers or directors of the Corporation to qualify,
any national securities exchange or system on which the Common Stock is then
listed or reported, or under any other applicable laws, rules, or regulations.
The provisions of the Purchase Plan that determine the amount, price, and time
of stock purchases by executive officers and directors may not be amended more
than once every six months other than to comply with changes in the Code, the
Employee Retirement Income Security Act of 1974, as amended (ERISA), or the
rules thereunder unless the Corporation's General Counsel determines that such
restriction on amendments is not necessary to secure or maintain any exemption
from Section 16 of the Securities Exchange Act of 1934, as amended, for which
the Corporation intends executive officers and directors to qualify. The
Purchase Plan will continue in effect until all shares authorized to be sold
thereunder have been sold, subject to the right of the Board of Directors to
terminate the Plan at any earlier time.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The Purchase Plan is intended to qualify as an "employee stock purchase
plan" within the meaning of Section 423 of the Code and, as a result,
participants will be afforded favorable tax treatment under Sections 421 and 423
of the Code. A participant in an offering under the Purchase Plan will not
recognize income subject to Federal income tax at the commencement of an
offering period or at the time shares are purchased. However, any discount from
the market price on the purchase date may be subject to employment taxes (FICA
and FUTA). No Federal income tax consequences result to the Corporation at the
commencement of an offering period under the Purchase Plan, upon the subsequent
purchases of Common Stock by participants, or upon the disposition of shares
acquired under the Purchase Plan other than with respect to a disqualifying
disposition. If no disposition of the shares purchased in an offering period is
made within two years from the commencement of such offering period nor within
one year from the date the shares are transferred to the employee, then upon
subsequent disposition of the shares, ordinary income may be recognized by the
participant, depending upon the purchase price formula applicable to that
offering, on up to fifteen percent (15%) of the market price of the shares on
such commencement date; any additional gain realized will be capital gain. Any
loss realized by an employee upon disposition of the shares will constitute a
capital loss.
 
     If the shares are disposed of within either the two-year or one-year
periods mentioned above (a so-called disqualifying disposition), the participant
will recognize ordinary income at the time of such disposition in an amount
equal to the difference between the fair market value of the shares at the time
such shares were purchased and the purchase price of the shares, and the
Corporation will generally be entitled to a corresponding deduction from its
income. Any difference between such fair market value and the disposition price
will be treated as capital gain or loss to the participant and will not be
deductible by the Corporation.
 
     As of November 23, 1995, a total of approximately 2,000 employees of the
Corporation and its subsidiaries, including all officers, are eligible to
participate in the Purchase Plan. However, it is not possible to determine how
many employees will elect to participate, the amount that participating
employees will elect to contribute, or the number of shares which may be
purchased and price thereof under the Plan. Because
 
                                       19
<PAGE>   22
 
purchases by all eligible employees is elective, the benefits that would have
been received by employees, or by any particular class of employees, for the
last fiscal year of the Corporation may not be determined. If the Purchase Plan
is not approved by shareholders, it will be null, void, and of no force or
effect.
 
     THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" APPROVAL OF THE
EMPLOYEE STOCK PURCHASE PLAN.
 
                                 PROPOSAL NO. 3
 
                PROPOSAL TO APPROVE THE KEY EMPLOYEE STOCK PLAN
 
GENERAL INFORMATION
 
     The Board of Directors has adopted, subject to shareholder approval, the
ONEOK Inc. Key Employee Stock Plan (Plan). The purposes of the Plan are to
provide competitive incentives that will enable the Corporation to attract,
retain, motivate and reward key employees, and to give key employees an interest
parallel to the interests of the Corporation's shareholders. The following
summary of the material features of the Plan is in all respects subject to and
qualified by reference to the actual text of the Plan, which appears in its
entirety in Exhibit B to this Proxy Statement.
 
     The Plan authorizes the Compensation Committee of the Board of Directors
(the Committee) to grant eligible employees options to purchase shares of ONEOK
Inc. Common Stock, without par value (Common Stock), which qualify for the
special tax treatment according to incentive stock options (Incentive Stock
Options) under Section 422 of the Internal Revenue Code of 1986, as amended (the
Code), as well as options to purchase shares of Common Stock which do not so
qualify (Nonqualified Stock Options). The Plan also authorizes the Committee to
grant eligible employees stock bonus awards, restricted stock awards, and
performance unit awards. The variety of stock incentive awards authorized to be
granted under the Plan, as well as the wide discretion which the Plan confers
upon the Committee to determine the terms and conditions of the awards, are
intended to give the Committee flexibility to adapt the Corporation's
equity-based compensation practices to the changing business and regulatory
environment in which it operates.
 
     If approved by shareholders, the Plan will remain in effect until stock
incentives have been granted with respect to all shares of Common Stock
authorized to be issued or transferred under the Plan or until the Plan is
sooner terminated by the Board of Directors. In accordance with applicable
provisions of the Code, no Incentive Stock Options may be granted under the plan
after August 17, 2005. If the Plan is not approved by shareholders, it will be
null, void, and of no force or effect.
 
     A total of 1,000,000 shares of Common Stock may be issued or transferred
pursuant to stock incentives granted under the Plan. Such shares may be
authorized and unissued shares or treasury shares or any combination thereof.
The Plan authorizes the Corporation to issue or transfer sufficient shares of
Common Stock to a trust (including a grantor trust) at any time, including upon
or in contemplation of a Change in Control, as defined below, to satisfy its
obligations under any then-outstanding awards previously granted under the Plan
(including stock options), in which case the shares may be treated as authorized
and issued shares while held in the trust with full dividend and voting rights,
whether or not the related awards are then vested or exercisable. The maximum
number of shares of Common Stock with respect to which stock options or other
stock incentives may be granted to any employee during the period in which stock
incentives may be granted under the Plan is 250,000 shares. Shares that cease to
be issuable under an award because of the termination, expiration, cancellation,
or forfeiture of the award, or because of the employee's failure to satisfy the
terms and conditions of the award will not count against the foregoing
limitations and may again be made subject to awards under the Plan. The Plan
provides for the number and class of shares authorized to be issued or
transferred under the Plan, the maximum number and class of shares with respect
to which stock options or other stock incentives may be granted to any employee,
the number and class of shares subject to outstanding grants, and the exercise
price of outstanding stock options to be adjusted equitably to prevent dilution
or enlargement of rights in the event of recapitalizations, stock splits, stock
dividends, mergers, and similar transactions.

     The class of persons who are eligible to be selected to participate in the
Plan consists of any employee of the Corporation or its subsidiaries, including
an officer or member of the Board of Directors who is an employee, who the
Committee determines is in a position to contribute significantly to the growth
and profitability of, or to perform services of major importance to, the
Corporation and its subsidiaries. The approximate number of persons who are
eligible to be selected to participate in the Plan at the present time is 50 and
is subject to change.
 
     The Plan is administered by the Committee, which, within the parameters set
forth in the Plan, determines the type of awards to grant, selects participants
from the class of employees eligible to participate, determines the number of
shares of Common Stock to be subject to each award, and determines the terms and
conditions of the awards (including the exercise price of options). The
Committee interprets the Plan and is authorized to make all determinations and
decisions thereunder. Under the Plan, the Committee must consist of two or more
members of the Board of Directors, each of whom qualifies as a "disinterested
person" under Securities and Exchange Commission (SEC) Rule 16b-3 and as an
"outside director" within the meaning of Section 162(m) of the Code, unless the
Corporation's Board of Directors determines otherwise. (SEC Rule 16b-3 exempts
certain transactions by executive officers and directors under employee benefit
plans such as the Plan from the short-swing trading rules of the Federal
securities law. As described in more detail under the section entitled "Certain
Federal Income Tax Consequences" on page 19 of this Proxy Statement, Section
162[m] of the Code limits the amount of executive compensation that publicly
traded corporations may deduct for Federal income tax purposes, subject to
certain exceptions.)
 
     Unless the Committee determines otherwise, transactions by executive
officers and directors under the Plan are intended to qualify for the exemptions
available under SEC Rule 16b-3, and awards granted to executive officers are
intended to qualify as "performance-based compensation" if such qualification is
necessary to preserve the Corporation's deduction for such awards under Code
Section 162(m). The Plan is specifically intended to give the Committee
authority to grant awards that will qualify as "performance-based compensation"
as well as awards that will not so qualify.
 
     The Plan also authorizes the Committee, after a stock incentive has been
granted and without consideration, to waive any term or condition that could
have been omitted from the award when it was granted and to amend the award to
include or exclude any term or condition that could have been included or
excluded from the award when it was granted.
 
     Except for the nonqualified stock options noted above, no options or other
stock incentive awards have been granted to date under the Plan. The amount of
options and benefits to be received by any individual under the Plan or that
would have been received by any individual under the Plan, if the Plan had been
in effect during the last fiscal year, are not determinable at the present time,
as all such determinations under the Plan are to be made by the Committee in its
sole discretion. The market value of a share of Common Stock on November 27,
1995, the latest practicable date before publication of this proxy statement,
was $23.75.
 
OPTIONS
 
     The price at which a share of Common Stock may be purchased under each
Incentive Stock Option will be at least one hundred percent (100%) of the fair
market value of a share of Common Stock on the date the Incentive Stock Option
is granted. The price at which a share of Common Stock may be purchased under
each Nonqualified Stock Option will be at least the par value (if any) of a
share of Common Stock. At the present time, a share of Common Stock has no par
value, therefore, the Committee has discretion to establish any purchase price
for shares with respect to which Nonqualified Stock Options are granted.
 
     The aggregate fair market value of the shares for which Incentive Stock
Options granted to any employee may be exercisable for the first time by such
employee during any calendar year (under all stock option plans of the
Corporation and its subsidiaries) may not exceed $100,000.
 
     An option granted under the Plan is exercisable during the optionee's
lifetime only by the optionee and is not transferable by the optionee except by
will, the laws of descent and distribution, or to a designated beneficiary.
However, the Committee may in its discretion authorize an employee who is
granted any stock
 
                                       21
<PAGE>   24
 
incentive other than Incentive Stock Option (including a Nonqualified Stock
Option) to transfer the stock incentive award during his or her lifetime to
members of his or her immediate family or to family trusts or partnerships
without consideration for estate planning purposes. In the event of such a
transfer, the stock incentive award would continue to be subject to
substantially the same terms and conditions as applied before the transfer
occurred.
 
     Options may be granted for such lawful consideration as the Committee may
determine when the options are granted. Such consideration may consist of money
or other property, tangible or intangible, or labor or services received or to
be received by the Corporation. For example, in the discretion of the Committee,
options may be granted in lieu of compensation that would otherwise be paid in
cash or in consideration of the employee's continuing in the Corporation's
employ for a period of time after the date the option is granted. Options may
become exercisable in full at the time of grant or at such other time or times
and in such installments as the Committee may determine. Options may be
exercised during such periods before and after the date on which the optionee
ceases to be an employee of the Corporation and its subsidiaries as the
Committee may determine. However, no option may be exercised after the tenth
anniversary of the date on which the option was granted.
 
     The purchase price of the shares subject to an option may be paid in cash,
in shares of Common Stock or other property already owned by the optionee, or by
the immediate sale through a stockbroker of that number of shares being acquired
sufficient to pay the purchase price. If an optionee pays the purchase price by
surrendering shares of Common Stock he or she already owns, such shares will be
valued at their fair market value on the date of such surrender and will be
added back to the number of shares available for issuance under the Plan. The
Committee is also authorized to permit the purchase price to be paid by means of
a promissory note executed by the optionee in favor of the Corporation and
secured by a pledge of the shares being acquired. Any such note would contain
terms approved by the Committee, may, but need not, bear interest (except in the
case of Incentive Stock Option, in which case the note must bear interest), and
would mature in ten years or less.
 
     The Committee may provide at the time of grant of an option (the Original
Option) that the employee shall be granted an additional option (a Restored
Option) in the event such employee pays the purchase price of the shares subject
to the Original Option or satisfies tax withholding liabilities arising from
exercise of the Original Option by surrendering shares of Common Stock the
employee already owns. Each Restored Option may cover the number of shares of
Common Stock equal to the number of shares of Common Stock surrendered by the
employee in payment of the purchase price or tax withholding liabilities, shall
have a purchase price per share of Common Stock subject to the Restored Option
equal to the fair market value of the Common Stock on the date of grant of such
Restored Option, and shall expire not later than on the stated expiration date
of the Original Option.
 
     Under the Plan, the fair market value of a share of Common Stock is
generally equal to the average of the high and low sale prices of a share of
Common Stock in consolidated trading on the date in question as reported by The
Wall Street Journal or another reputable source designated by the Committee.
 
     The Plan provides for all options to become exercisable in full after a
change in a majority of the Board of Directors as a result of a merger, tender
offer, exchange offer, or contested election; after any person becomes the
beneficial owner of more than twenty percent (20%) of the Common Stock of the
Corporation; and after shareholders approve a merger, sale of assets, or plan of
complete liquidation (Change in Control).
 
     The Plan provides that after an option has been granted, the Committee may,
without consideration, accelerate the date on which the option becomes
exercisable or, if granted for a term of less than ten years, extend the term to
up to ten years after the date the option was granted.
 
STOCK BONUS, RESTRICTED STOCK, AND PERFORMANCE UNIT AWARDS
 
     The Committee may provide for the Corporation to distribute cash or shares
of Common Stock to eligible employees or to agree to distribute cash or shares
of Common Stock at a future time or times, subject to such terms and conditions
(including forfeiture restrictions) as the Committee may impose, in lieu of
compensation
 
                                       22
<PAGE>   25
 
that may have been earned by past services, or as a supplement to compensation
earned by past services (in either event, Stock Bonus Awards). The amount of any
Stock Bonus Award may be, but need not be, determined by reference to the market
value of Common Stock. If shares are to be issued at a future time or times, the
Committee may provide, but need not provide, for payment to the participant of
amounts equal to the dividends that would have been paid to the participant if
issuance of the shares had not been deferred until such future time or times, or
for such amounts to be credited to the participant in the form of additional
deferred stock units.
 
     The Committee may also provide for shares of Common Stock to be issued to
an eligible employee prior to the employee's satisfying continued employment
and/or other performance objectives or contingencies specified by the Committee
at the time of grant (Restricted Stock) or may provide for shares to be issued
after the employee satisfies such objectives or contingencies (Performance Unit
Awards). Any Restricted Shares will be forfeitable to the Corporation until such
objectives or contingencies are satisfied unless the Committee provides
otherwise; but upon issuance of Restricted Stock, the recipient will become a
shareholder of the Corporation with full dividend and voting rights, except to
the extent that the Committee provides otherwise. Performance objectives may
include, but need not include, corporate, divisional, business unit, or
individual financial or operating performance measures. Upon satisfaction of any
objectives or contingencies specified by the Committee, stock certificates
evidencing the Restricted Shares will be delivered to the participant free and
clear of any restrictions without the payment of any cash consideration by the
participant.
 
     Stock Bonus Awards, Restricted Stock Awards, and Performance Unit Awards
may, in the discretion of the Committee, be settled in cash in lieu of shares of
Common Stock, in which case the number of shares for which cash is paid will
generally be added back to the number of shares authorized to be issued under
the Plan.
 
CERTAIN CHANGE IN CONTROL PROVISIONS
 
     The Plan provides that all awards that are outstanding under the Plan at
the time of a Change in Control, whether they be Incentive Stock Options,
Nonqualified Stock Options, Restricted Stock Awards, Performance Unit Awards, or
Stock Bonus Awards, will become fully exercisable, nonforfeitable, and payable
when any Change in Control occurs. In the event of a Change in Control less than
six months after the date on which an award was granted in consideration of the
employee's future services, the participant agrees in writing (if requested by
the Committee to do so) to remain in the Corporation's employ at least through
the end of such six-month period on the same terms and conditions (including
compensation) as before any Change in Control. In addition, the Plan authorizes
the Committee to grant options that become exercisable and Restricted Shares,
Performance Units, and Stock Bonus Awards that become nonforfeitable and payable
only in the event of a Change in Control, and to provide for cash to be paid in
settlement of any award under the Plan in such event.
 
AMENDMENT OF THE PLAN
 
     The Board of Directors may amend the Plan at any time and in any respect
without shareholder approval unless shareholder approval of the amendment in
question is required under Delaware law; the Code; any applicable exemption from
Section 16 of the Securities Exchange Act of 1934, as amended, for which the
Corporation intends transactions by executive officers or directors to qualify;
any national securities exchange or system on which the Common Stock is then
listed or reported; or under any other applicable laws, rules, or regulations.
The Board of Directors may also terminate the Plan at any time. However, no
amendment or termination of the Plan may adversely affect any awards that were
granted before the date of such amendment or termination without the consent of
the participant.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     THE FOLLOWING BRIEF DESCRIPTION OF THE TAX CONSEQUENCES OF AWARDS UNDER THE
PLAN IS BASED ON FEDERAL INCOME TAX LAWS CURRENTLY IN EFFECT AND DOES NOT
PURPORT TO BE A COMPLETE DESCRIPTION OF SUCH FEDERAL INCOME TAX CONSEQUENCES.
 
                                       23
<PAGE>   26
 
     LIMITATION ON CORPORATE DEDUCTIONS FOR CERTAIN EXECUTIVES' COMPENSATION.
Under Section 162(m) of the Code, the amount which the Corporation may deduct on
its Federal income tax return for compensation paid to certain "covered
employees" (generally the chief executive officer and the four highest-paid
officers other than the chief executive officer) in any taxable year is
generally limited to $1 million per individual. However, compensation that
qualifies as "performance-based compensation" is not subject to the $1 million
deduction limit. As mentioned under "General Information" above, the Plan
authorizes the Committee to grant awards under the Plan that qualify as
"performance-based compensation" as well as awards that do not. As a result, the
Corporation may not be entitled to any tax deduction for the awards mentioned
below if the individual in question is a "covered employee"; the amount in
question does not qualify as "performance-based compensation"; and the amount in
question, when added to the covered employee's other taxable compensation that
is not "performance-based" in the same taxable year, exceeds $1 million. At the
present time, the Corporation expects any options granted under the Plan to
qualify as "performance based" and does not anticipate that deductions for
awards under the Plan will be limited by the provisions of Section 162(m) of the
Code.
 
     OPTIONS. There are no Federal income tax consequences either to the
optionee or the Corporation upon the grant of an Incentive Stock Option or a
Nonqualified Stock Option. If shares are purchased under an Incentive Stock
Option (i.e., an Incentive Stock Option is exercised) during employment or
within three months thereafter, the optionee will not recognize any income and
the Corporation will not be entitled to a deduction in respect of the option
exercise. However, the excess of the fair market value of the shares on the date
of such exercise over the purchase price of the shares under the option will be
includible in the optionee's alternative minimum taxable income if the optionee
does not dispose of the shares in the same calendar year in which the optionee
acquired the shares under the Incentive Stock Option, which may give rise to
alternative minimum tax liability for the optionee. Generally, if the optionee
disposes of shares purchased under an Incentive Stock Option within two years of
the date of grant or one year of the date of exercise of the Incentive Stock
Option, the optionee will recognize ordinary income, and the Corporation will be
entitled to a deduction equal to the excess of the fair market value of the
shares on the date of exercise over the purchase price of such shares (but not
more than the actual gain realized by the optionee on the disposition of the
shares). Any gain after the date on which the optionee purchased the shares will
be treated as capital gain to the optionee and will not be deductible by the
Corporation. If the shares are disposed of after the two-year and one-year
periods mentioned above, the Corporation will not be entitled to any deduction,
and the entire gain or loss realized by the optionee will be treated as capital
gain or loss.
 
     When shares are purchased under a Nonqualified Stock Option, the excess of
the fair market value of the shares on the date of purchase over the purchase
price of such shares under the option will generally be taxable to the optionee
as ordinary income and deductible by the Corporation. The disposition of shares
purchased under a Nonqualified Stock Option will generally result in a capital
gain or loss for the optionee but will have no tax consequences for the
Corporation.
 
     STOCK BONUS AWARDS. If shares of Common Stock are issued pursuant to a
Stock Bonus Award, the recipient will generally recognize ordinary income, and
the Corporation will generally be entitled to a tax deduction equal to the fair
market value of the shares on the date the shares are issued less any amount
paid for them by the recipient.
 
     RESTRICTED STOCK AWARDS. An employee who has been awarded Restricted Stock
will not recognize taxable income at the time the Restricted Stock is issued
unless the employee makes a special election in accordance with applicable
Treasury regulations to be taxed at ordinary income rates on the fair market
value of the shares at the time (with fair market value determined for this
purpose without regard to any restrictions other than restrictions, if any,
which by their terms will never lapse), in which case the Corporation would, at
the same time, be entitled to a deduction equal to the amount of income realized
by the employee but would not be entitled to deduct any dividends paid on the
shares. Absent such an election, an employee who has been awarded Restricted
Stock will not recognize taxable income until the shares become transferable or
cease to be subject to a substantial risk of forfeiture, at which time the
recipient will recognize ordinary income and the Corporation will be entitled to
a corresponding deduction equal to the excess of the fair market value of the
shares at the time over the amount (if any) paid by the recipient for the
shares. Dividends paid to the recipient
 
                                       24
<PAGE>   27
 
on the Restricted Stock prior to that time will be ordinary compensation income
to the recipient and deductible by the Corporation.
 
     PERFORMANCE UNIT AWARDS. An employee who has been granted Performance Units
will not recognize taxable income, and the Corporation will not be entitled to a
deduction at the time Performance Units are granted. At the time the employee
receives cash or shares of Common Stock in payment of Performance Units, the
employee will recognize ordinary income equal to the sum of the cash and the
fair market value of any shares of Common Stock at such time, and the
Corporation will be entitled to a corresponding deduction. To the extent
Performance Units are paid in shares of Restricted Stock, the Federal income tax
consequences above applicable to Restricted Stock Awards will apply.
 
     THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" APPROVAL OF THE KEY
EMPLOYEE STOCK PLAN.
 
                                 PROPOSAL NO. 4
 
              RATIFICATION AND APPROVAL OF APPOINTMENT OF AUDITOR
 
     The Board of Directors, based on the recommendation of the Audit Committee,
appointed the firm of KPMG Peat Marwick LLP independent auditor to examine the
books of account and other records of the Corporation and its consolidated
subsidiaries for the 1996 Fiscal Year. The Board of Directors is asking the
shareholders to ratify and approve this action. KPMG Peat Marwick LLP has been
the Corporation's independent auditor since 1951, and the audit engagement
partner is normally rotated every five years. Representatives of the auditing
firm will be present at the meeting and will be afforded the opportunity, if
they so desire, to make a statement or respond to appropriate questions that may
come before the meeting.
 
     Although such ratification is not required by law, the Board of Directors
believes that shareholders should be given the opportunity to express their
views on the subject. The Board has asked for such ratification since 1983.
While not binding on the Board of Directors, the failure of the shareholders to
ratify the appointment of KPMG Peat Marwick LLP as the Corporation's independent
auditor would be considered by the Board in determining whether or not to
continue with the services of KPMG Peat Marwick LLP.
 
                             SHAREHOLDER PROPOSALS
 
     Any shareholder proposal to be presented at the Annual Meeting to be held
January 16, 1997, must be received by the Corporation on or before August 12,
1996, for inclusion in the Corporation's Proxy Statement and form of proxy
relating to that meeting.
 
                                 OTHER MATTERS
 
     The management of the Corporation knows of no other matters that are likely
to be brought before the meeting.

meanings:
 
          (a) "Base Compensation" means, with respect to any offering period:

3. ADMINISTRATION.
 
     (a) The Plan shall be administered by a committee of the Board consisting

4. STOCK SUBJECT TO THE PLAN.
 
     (a) Subject to paragraph (c) below, the aggregate number of shares of
Common Stock which may be sold under the Plan is 350,000.
 
     (b) If the number of shares of Common Stock that participating employees
become entitled to purchase is greater than the number of shares of Common Stock
that are offered in a particular offering or that remain available under the
Plan, the available shares of Common Stock shall be allocated by the Committee
among such participating employees in such manner as it deems fair and
equitable.
 
     (c) In the event of any change in the Common Stock, through
recapitalization, merger, consolidation, stock dividend or split, combination or
exchange of shares, spinoff or otherwise, the Committee may make such equitable
adjustments in the Plan and the then outstanding offerings as it deems necessary
and appropriate including, but not limited to, changing the number of shares of
Common Stock reserved under the Plan, and the price of the current offering;
provided that any such adjustments shall be consistent with Sections 423 and 424
of the Code.
 
     (d) Shares of Common Stock which are to be delivered under the Plan may be
obtained by the Company from its treasury, by purchases on the open market or
from private sources, or by issuing authorized but unissued shares of its Common
Stock. Shares of authorized but unissued Common Stock may not be delivered under
the Plan if the purchase price thereof is less than the par value (if any) of
the Common Stock at the time. The Committee may (but need not) provide at any
time or from time to time (including without limitation upon or in contemplation
of a change in control) for a number of shares of Common Stock equal in number
to the number of shares then subject to options under this Plan, or expected to
be subject to options under this Plan in the then pending offering(s), to be

such options, and, unless prohibited by applicable law, such shares held in
trust shall be considered authorized and issued shares with full dividend and
voting rights, notwithstanding that the options to which such shares relate
might not be exercisable at the time. No fractional shares of Common Stock shall
be issued or sold under the Plan.
 
5. ELIGIBILITY.
 
     All employees of the Company and any Subsidiaries designated by the
Committee from time to time will be eligible to participate in the Plan, in
accordance with and subject to such rules and regulations as the Committee may
prescribe; provided, however, that (a) such rules shall neither permit nor deny
participation in the Plan contrary to the requirements of the Code (including
but not limited to Section 423(b)(3), (4) and (8) thereof), (b) no employee
shall be eligible to participate in the Plan if his or her customary employment
is 20 hours or less per week or for not more than 5 months in any calendar year
or if he or she has been employed by the Company or a participating Subsidiary
for less than one year, unless the Committee determines otherwise on a uniform
and non-discriminatory basis, (c) no employee may be granted an option under the
Plan if such employee, immediately after the option is granted, owns stock
possessing 5% or more of the total combined voting power or value of all classes
of stock of his or her employer corporation or any parent or Subsidiary
corporation (within the meaning of Section 423(b)(3) of the Code). For purposes
of the preceding sentence, the rules of Section 424(d) of the Code shall apply
in determining the stock ownership of an employee, and stock which the employee
may purchase under outstanding options (whether or not such options qualify for
the special tax treatment afforded by Code Section 421(a)) shall be treated as
stock owned by the employee; and (d) all participating employees shall have the
same rights and privileges except as otherwise permitted by Section 423(b)(5) of
the Code.
 
6. OFFERINGS; PARTICIPATION.
 
     The Company may make offerings of up to 27 months' duration each, to
eligible employees to purchase Common Stock under the Plan, until all shares
authorized to be delivered under the Plan have been exhausted or until the Plan
is sooner terminated by the Board. Subject to the preceding sentence, the
duration and commencement date of any offerings shall be determined by the
Committee in its sole discretion; provided that, unless the Committee determines
otherwise, a new offering shall commence on the first day of the Company's first
payroll period coinciding with or next following each January 1 after the
effective date of this Plan and shall extend through and include the payroll
period immediately preceding the payroll period in which the next offering
commences. Subject to such rules, procedures and forms as the Committee may
prescribe, an eligible employee may participate in an offering at such time(s)
as the Committee may permit by authorizing a payroll deduction for such purpose
of up to a maximum of ten percent of his or her Base Compensation or such lesser
amount as the Committee may prescribe. The Committee may (but need not) permit
employee contributions to be made by means other than payroll deductions,
provided that in no event shall an employee's contributions from all sources in
any offering exceed ten percent of his or her Base Compensation or such lesser
amount as the Committee may prescribe. The Committee may at any time suspend or
accelerate the completion of an offering if required by law or deemed by the
Committee to be in the best interests of the Company, including in the event of
a change in ownership or control of the Company or any Subsidiary. The Company's
obligation to sell and deliver Common Stock under this Plan shall be subject to
the approval of any governmental authority whose approval the General Counsel
determines is necessary or advisable to obtain in connection with the
authorization, issuance or sale of such Common Stock.
 
7. PAYROLL DEDUCTIONS.
 
     (a) The Company will maintain payroll deduction accounts on its books for
all participating employees. All employee contributions shall be credited to
such accounts. Employee contributions credited to the payroll deduction accounts
of participating employees need not be segregated from other corporate funds and
may be used for any corporate purpose.
 
                                       A-3
<PAGE>   31
 
     (b) At such times as the Committee may permit and subject to such rules,
procedures and forms as the Committee may prescribe, an employee may increase,
decrease or suspend his or her payroll deduction during an offering, or may
withdraw the balance of his or her payroll deduction account and thereby
withdraw from participation in an offering. However, an employee may at any time
waive in writing the right or privilege to decrease or suspend his or her
payroll deductions or withdraw from participation in a particular offering for a
period of at least six months. Any such waiver shall be irrevocable with respect
to the period ending six months after the employee files a superseding written
revocation of such waiver with the
 
     (c) No employee shall make any elective contribution or employee
contribution to the Plan (within the meaning of Treasury Regulation Section
1.401(k)-1(d)(2)(iv)(B)(4)) during the balance of the calendar year after the
employee's receipt of a hardship distribution from a plan of the Company or a
related party within the provisions of Code Section 414(b), (c), (m) or (o)
containing a cash or deferred arrangement under Section 401(k) of the Code, or
during the following calendar year. The foregoing sentence shall not apply if
and to the extent the General Counsel determines it is not necessary to qualify
any such plan as a cash or deferred arrangement under Section 401(k) of the
Code.
 
     (d) Any balance remaining in any employee's payroll deduction account at
the end of an offering period will be carried forward into the employee's
payroll deduction account for the following offering period. In no event will
the balance carried forward be equal to or greater than the purchase price of
one share of Common Stock as determined under Section 8(c) below. Any excess
shall be refunded to the participant. Upon termination of the Plan, all amounts
in the accounts of participating employees shall be carried forward into their
payroll deduction accounts under a successor plan, if any, or refunded to them,
as the Committee may decide.
 
     (e) In the event of the termination of a participating employee's
employment for any reason, his or her participation in any offering under the
Plan shall cease, no further amounts shall be deducted pursuant to the Plan and
the balance in the employee's account shall be paid to the employee, or, in the
event of the employee's death, to the employee's beneficiary under the Company's
basic group life insurance program.
 
8. PURCHASE; LIMITATIONS.
 
     (a) Within the limitations of Section 8(d) below, each employee
participating in any offering under the Plan will be granted an option, upon the
effective date of such offering, for as many full shares of Common Stock as the
amount of his or her payroll deduction account (including any contributions made
by means other than payroll deductions) at the end of the offering can purchase.
 
     (b) As of the last day of the offering period, the payroll deduction
account of each participating employee shall be totalled. Subject to the
provisions of Section 7(b) above and 8(d) below, if such account contains
sufficient funds as of that date to purchase one or more full shares of Common
Stock at the price determined under Section 8(c) below, the employee shall be
deemed to have exercised an option to purchase the largest number of full shares
of Common Stock at the price determined under Section 8(c) below that his or her
payroll deduction account will permit; such employee's account will be charged
for the amount of the purchase and for all purposes under the Plan the employee
will be deemed to have acquired the shares on that date; and either a stock
certificate representing such shares will be issued to him or her, or the
Company's registrar will make an entry on its books and records evidencing that
such shares have been duly issued or transferred as of that date, as the
Committee may direct. Notwithstanding any provision of the Plan to the contrary,
the Committee may but need not permit fractional shares to be purchased under
the Plan.
 
     (c) Unless the Committee determines before the effective date of an
offering that a higher price that complies with Section 423 of the Code shall
apply, the purchase price of the shares of Common Stock which are to be sold
under the offering shall be the lesser of (i) an amount equal to 85 percent of
the Fair Market Value of the Common Stock at the time such option is granted, or
(ii) an amount equal to 85 percent of the Fair Market Value of the Common Stock
at the time such option is exercised.
 
     (d) In addition to any other limitations set forth in the Plan, (i) no
employee may purchase in any offering period more than the number of shares of
Common Stock determined by dividing the employee's
 
                                       A-4
<PAGE>   32
 
annual Base Compensation as of the first day of the offering period, or $25,000,
whichever is less, by the Fair Market Value of a share of Common Stock at such
day, and (ii) no employee may be granted an option under the Plan which permits
his or her rights to purchase stock under the Plan, and any other stock purchase
plan of his or her employer corporation and its parent and subsidiary
corporations that is qualified under Section 423 of the Code, to accrue at a
rate which exceeds $25,000 of the Fair Market Value of such stock (determined at
the time such option is granted) for each calendar year in which the option is
outstanding at any time. The Committee may further limit the amount of Common
Stock which may be purchased by any employee during an offering period in
accordance with Section 423(b)(5) of the Code.
 
9. NO TRANSFER.
 
     (a) No option, right or benefit under the Plan (including any derivative
security within the meaning of paragraph (a)(2) of SEC Rule 16b-3) may be
transferred by a participating employee, whether by will, the laws of descent
and distribution, or otherwise, and all options, rights and benefits under the
Plan may be exercised during the participating employee's lifetime only by such
employee.
 
     (b) Book entry accounts and certificates for shares of Common Stock
purchased under the Plan may be maintained or registered, as the case may be,
only in the name of the participating employee or, if such employee so indicates
on his or her payroll deduction authorization form, in his or her name jointly
with a member of his or her family, with right of survivorship. An employee who
is a resident of a jurisdiction which does not recognize such a joint tenancy
may have book entry accounts maintained and certificates registered in the
employee's name as tenant in common with a member of the employee's family,
without right of survivorship.
 
10. EFFECTIVE DATE AND DURATION OF PLAN.
 
     The Plan shall become effective when adopted by the Board, provided that
the stockholders of the Company approve it within 12 months thereafter at a duly
held stockholders' meeting. If not so approved by shareholders, the Plan shall
be null, void and of no force or effect. If so approved, the Plan shall remain
in effect until all shares authorized to be issued or transferred hereunder have
been exhausted or until the Plan is sooner terminated by the Board of Directors,
and may continue in effect thereafter with respect to any options outstanding at
the time of such termination if the Board of Directors so provides.
 
11. AMENDMENT AND TERMINATION OF THE PLAN.
 
     The Plan may be amended by the Board of Directors, without shareholder
approval, at any time and in any respect, unless shareholder approval of the
amendment in question is required under Delaware law, the Code (including
without limitation Code Section 423 and Treasury Regulation Section
1.423-2(c)(4) thereunder), any exemption from Section 16 of the Exchange Act
(including without limitation SEC Rule 16b-3) for which the Company intends
Section 16 Persons to qualify, any national securities exchange or system on
which the Stock is then listed or reported, by any regulatory body having
jurisdiction with respect to the Plan, or under any other applicable laws, rules
or regulations. The Plan provisions that determine the amount, price and timing
of option grants to Section 16 Persons may not be amended more than once every
six months, other than to comport with changes in the Internal Revenue Code, the
Employee Retirement Income Security Act of 1974, or the rules thereunder, unless
the General Counsel determines that such restriction on amendments is not
necessary to secure or maintain any exemption from Section 16 of the Exchange
Act for which the Company intends Section 16 Persons to qualify. The Plan may
also be terminated at any time by the Board of Directors.
 
12. GENERAL PROVISIONS.
 
     (a) Nothing contained in this Plan shall be deemed to confer upon any
person any right to continue as an employee of or to be associated in any other
way with the Company for any period of time or at any particular rate of
compensation.
 
                                       A-5

     (b) No person shall have any rights as a stockholder of the Company with
respect to any shares optioned under the Plan until such shares are issued or
transferred to him or her.
 
     (c) All expenses of adopting and administering the Plan shall be borne by
the Company, and none of such expenses shall be charged to any participant.
 
     (d) The Plan shall be governed by and construed under the laws of the State
of Delaware, without giving effect to the principles of conflicts of laws of
that State.
 
     (e) The Plan and each offering under the Plan is intended to qualify as an
"employee stock purchase plan" within the meaning of Section 423 of the Code.
Transactions under the Plan by or with respect to Section 16 Persons are also
intended to qualify for exemption under SEC Rule 16b-3, unless the Committee
specifically determines otherwise. Every provision of the Plan shall be
administered, interpreted and construed to carry out those intentions, and any
provision that cannot be so administered, interpreted and construed shall to
that extent be disregarded.

and no additional consideration need be received by the Company in exchange for
such waiver or amendment.
 
4. STOCK SUBJECT TO THE PLAN
 
     (a) Subject to the provisions below of paragraph 4(c) and of Section 8, the
maximum number of shares of Common Stock which may be issued or transferred
pursuant to Stock Incentives is 1,000,000 shares of Common Stock and the maximum
number of shares of Common Stock with respect to which Options or other Stock
Incentives may be granted to any employee during the period (specified in

250,000 shares of Common Stock.
 
     (b) Such shares may be authorized but unissued shares of Common Stock,
shares of Common Stock held in treasury, whether acquired by the Company
specifically for use under this Plan or otherwise, or shares issued or
transferred to, or otherwise acquired by, a trust pursuant to paragraph 11(d)
below, as the Committee may from time to time determine, provided, however, that
any shares acquired or held by the Company for the purposes of this Plan shall,
unless and until issued or transferred to a trust pursuant to paragraph 11(d)
below or to a Participant in accordance with the terms and conditions of a Stock
Incentive, be and at all times remain authorized but unissued shares or treasury
shares (as the case may be), irrespective of whether such shares are entered in
a special account for purposes of this Plan, and shall be available for any
corporate purpose.
 
     (c) If any shares of Common Stock subject to a Stock Incentive shall not be
issued or transferred to a Participant and shall cease to be issuable or
transferable to a Participant because of the termination, expiration or
cancellation, in whole or in part, of such Stock Incentive or for any other
reason, or if any such shares shall, after issuance or transfer, be reacquired
by the Company because of the Participant's failure to comply with the terms and
conditions of a Stock Incentive or for any other reason, the shares not so
issued or transferred, or the shares so reacquired by the Company, as the case
may be, shall no longer be charged against the limitations provided for in
paragraph (a) above of this Section 4 and may again be made subject to Stock
Incentives; provided that the number of shares not so issued or transferred and
any such reacquired shares may again be made subject to Stock Incentives for
Section 16 Persons only if the General Counsel determines that doing so would
not jeopardize any exemption from Section 16 of the Exchange Act (including
without limitation SEC Rule 16b-3) for which the Company intends Section 16
Persons to qualify. If a Participant pays the purchase price of shares subject
to an Option by surrendering shares of Common Stock in accordance with the
provisions of paragraph 6(b)(iv) below, the number of shares surrendered shall
be added back to the number of shares available for issuance or transfer under
the Plan so that the maximum number of shares that may be issued or transferred
under the Plan pursuant to paragraph 4(a) above shall have been charged only for
the net number of shares issued or transferred pursuant to the Option exercise.

transferred to a Participant at the time such Award is granted, or at any time
subsequent thereto, or in installments from time to time, and subject to such
terms and conditions, as the Committee shall determine. In the event that any
such issuance or transfer shall not be made to the Participant at the time such
Award is granted, the Committee may but need not provide for payment to such
Participant, either in cash or shares of Common Stock, from time to time or at
the time or times such shares shall be issued or transferred to such
Participant, of amounts not exceeding the dividends which would have been
payable to such Participant in respect of such shares (as adjusted under Section
8) if such shares had been issued or transferred to such Participant at the time
such Award was granted.
 
     (c) Any Stock Bonus Award, Performance Unit Award or Restricted Stock Award
may, in the discretion of the Committee, be settled in cash, on each date on
which shares would otherwise have been delivered or become unrestricted, in an
amount equal to the Fair Market Value on such date of the shares which would
otherwise have been delivered or become unrestricted; and the number of shares
for which such cash payment is made shall be added back to the maximum number of
shares available for use under the Plan, provided that the number of shares for
which such cash payment is made may be made subject to Stock Incentives for
Section 16 Persons only if the General Counsel determines that doing so would
not jeopardize any exemption from Section 16 of the Exchange Act (including
without limitation SEC Rule 16b-3) for which the Company intends Section 16
Persons to qualify.
 
     (d) Stock Bonus Awards, Performance Unit Awards and Restricted Stock Awards
shall be subject to such terms and conditions, including, without limitation,
restrictions on the sale or other disposition of the shares issued or
transferred pursuant to such Award, and conditions calling for forfeiture of the
Award or the shares issued or transferred pursuant thereto in designated
circumstances, as the Committee shall determine; provided however, that upon the
issuance or transfer of shares to a Participant pursuant to any such Award, the
recipient shall, with respect to such shares, be and become a shareholder of the
Company fully entitled to receive dividends, to vote and to exercise all other
rights of a shareholder except to the extent otherwise provided in the Award.
All or any portion of a Stock Bonus Award may but need not be made in the form
of a Performance Unit Award or a Restricted Stock Award.
 
     (e) Each Stock Bonus Award, Performance unit Award and Restricted Stock
Award shall be evidenced by a written instrument in such form as the Committee
shall determine, signed by an officer of the Company duly authorized to do so,
provided that such instrument is consistent with this Plan and incorporates it
by reference.

Incentive Stock Option is granted, owns stock possessing more than 10 percent of
the total combined voting power of all classes of stock of his or her employer
corporation or of its parent or subsidiary corporation, not less than 110
percent of the Fair Market Value of a share of Common Stock on the date the
Incentive Stock Option is granted) and, in the case of a Non-Statutory Stock
Option, not less than the par value (if any) of a share of Common Stock on the
date the Non-Statutory Stock Option is granted. A Non-Statutory Stock Option may
(but need not) entitle the Participant to purchase shares of Common Stock at any
fixed discount specified by
 
                                       B-4
<PAGE>   38
 
the Committee from Fair Market Value on the date of purchase. Subject to the
foregoing limitations, the purchase price per share may, if the Committee so
provides at the time of grant of an Option, be indexed to the increase or
decrease in an index specified by the Committee.
 
     (b) The purchase price of shares subject to an Option may be paid in whole
or in part (i) in cash, (ii) by bank-certified, cashier's or personal check
subject to collection, (iii) if so provided in the Option and subject to such
terms and conditions as the Committee may impose, by delivering to the Company a
properly executed exercise notice together with a copy of irrevocable
instructions to a stockbroker to sell immediately some or all of the shares
acquired by exercise of the Option and to deliver promptly to the Company an
amount of sale proceeds (or, in lieu of or pending a sale, loan proceeds)
sufficient to pay the purchase price, or (iv) if so provided in the Option and
subject to such terms and conditions as are specified in the Option, in shares
of Common Stock or other property surrendered to the Company. Property for
purposes of this paragraph shall include an obligation of the Company unless
prohibited by applicable law. Shares of Common Stock thus surrendered shall be
valued at their Fair Market Value on the date of exercise. Any such other
property thus surrendered shall be valued at its fair market value on any
reasonable basis established or approved by the Committee. If so provided in the
Option and subject to such terms and conditions as are specified in the Option,
in lieu of the foregoing methods of payment, any portion of the purchase price
of the shares to be issued or transferred may be paid by a promissory note
secured by pledge of the purchased shares in such form and containing such
provisions (which may but need not provide for interest and for payment of the
note at the election of the Participant in cash or in shares of Common Stock or
other property surrendered to the Company) as the Committee may approve;
provided that (A) if the Committee permits any such note to be paid by surrender
of shares of Common Stock, such shares shall be valued at their Fair Market
Value on the date of such surrender, and (B) if the Committee permits any such
note to be paid by surrender of other property, such other property shall be
valued at its fair market value on any reasonable basis established or approved
by the Committee, and (C) in the case of an Incentive Stock Option, any such
note shall bear interest at the minimum rate required to avoid imputation of
interest under federal income tax laws applicable at the time of exercise and
(D) any such note shall mature in ten years or such lesser period as may be
specified by the Committee.
 
     (c) Options may be granted for such lawful consideration, including money
or other property, tangible or intangible, or labor or services received or to
be received by the Company, as the Committee may determine when the Option is
granted. Property for purposes of the preceding sentence shall include an
obligation of the Company unless prohibited by applicable law. Subject to the
foregoing and the other provisions of this Section 6, each Option may be
exercisable in full at the time of grant or may become exercisable in one or
more installments, at such time or times and subject to satisfaction of such
terms and conditions as the Committee may determine. The Committee may at any
time accelerate the date on which an Option becomes exercisable, and no
additional consideration need be received by the Company in exchange for such
acceleration. Unless otherwise provided in the Option, an Option, to the extent
it becomes exercisable, may be exercised at any time in whole or in part until
the expiration or termination of the Option.
 
     (d) Each Option shall be exercisable during the life of the optionee only
by him or her or his or her guardian or legal representative, and after the
death only by his or her Beneficiary or, absent a Beneficiary, by his or her
estate or by a person who acquired the right to exercise the Option by will or
the laws of decent and distribution; provided that an Option of a Section 16
Person and any Incentive Stock Option may be exercisable after death by a
Beneficiary only if such exercise would be, in the opinion of the General
Counsel, permissible under and consistent with SEC Rule 16b-3 or Section 422 of
the Code, as the case may be. Each Option shall expire at such time or times as
the Committee may determine, provided that notwithstanding any other provision
of this Plan, (i) no Option shall be exercisable after the tenth anniversary of
the date the Option was granted, and (ii) no Incentive Stock Option which is
granted to any optionee who, at the time such Option is granted, owns stock
possessing more than 10 percent of the total combined voting power of all
classes of stock of his or her employer corporation or of its parent or
subsidiary corporation, shall be exercisable after the expiration of five (5)
years from the date such Option is granted. If an Option is granted for a term
of less than ten years, the Committee may, at any time prior to the expiration
of the Option, extend its term for a period ending not later than on the tenth
anniversary of the date the Option was granted, and no
 
                                       B-5
<PAGE>   39
 
additional consideration need be received by the Company in exchange for such
extension. The Committee may but need not provide for an Option to be
exercisable after termination of employment until its fixed expiration date (or
until an earlier date or specified event occurs).
 
     (e) An Option may, but need not, be an Incentive Stock Option. All shares
of Common Stock which may be made subject to Stock Incentives under this Plan
may be made subject to Incentive Stock Options; provided that the aggregate Fair
Market Value (determined as of the time the Option is granted) of the stock with
respect to which Incentive Stock Options may be exercisable for the first time
by any Key Employee during any calendar year (under all plans, including this
Plan, of his or her employer corporation and its parent and subsidiary
corporations) shall not exceed $100,000 or such other amount as may apply under
the Code.
 
     (f) Each Option shall be evidenced by a written instrument, signed by an
officer of the Company duly authorized to do so, which shall contain such terms
and conditions, and shall be in such form, as the Committee shall determine,
provided the instrument is consistent with this Plan and incorporates it by
reference. An Option, if so approved by the Committee, may include terms,
conditions, restrictions and limitations in addition to those provided for in
this Plan including, without limitation, terms and conditions providing for the
transfer or issuance of shares, on exercise of an Option, which may be
non-transferable and forfeitable to the Company in designated circumstances.
 
     (g) The Committee may specify, at the time of grant of an Incentive Stock
Option or, with respect to a No-Statutory Stock Option, at or after the time of
grant, that a Participant shall be granted a Non-Statutory Stock Option (a
"Restored Option") if and when (i) such Participant exercise all or part of an
Option, including a previously granted Restored Option, (an "Original Option")
by surrendering shares of Common Stock already owned by him or her in full or
partial payment of the Option price under such Original Option and/or (ii)
shares of Common Stock are surrendered or withheld to satisfy tax obligations
incident to the exercise of such Original Option. All Restored Options shall be
subject to the availability of shares of Common Stock under the Plan at the time
of such exercise. A Restored Option shall cover a number of shares of Common
Stock not greater than the number of shares of Common Stock surrendered in
payment of the option price under such Original Option and/or used to satisfy
any tax obligation incident to the exercise of such Original Option. Each
Restored Option shall have an option price equal to the Fair Market Value of the
Common Stock on the date of grant of the Restored Option and shall expire on the
stated expiration date of the Original Option. The date of grant of a Restored
Option shall be the date on which the exercise of the Original Option or a
previously granted Restored Option resulted in the grant of such Restored
Option. A Restored Option shall be exercisable at any time and from time to time
from or after the date of grant of the Restored Option (or as the Committee in
its sole discretion shall otherwise specify in the written instrument evidencing
the Restored Option). The written instrument evidencing a Restored Option shall
contain such other terms and conditions, which may include a restriction on the
transferability of the Common Stock received upon the exercise of the Original
Option or Restored Option, as the Committee in its sole discretion may deem
desirable.
 
     (h) No Participant shall make any elective contribution or employee
contribution to the Plan (within the meaning of Treasury Regulation Section
1.401(k)-1(d)(2)(iv)(B)(4) during the balance of the calendar year after the
Participant's receipt of a hardship distribution from a plan of the Company or a
related party within the provisions of Code Sections 414(b), (c), (m) or (o)
containing a cash or deferred arrangement under Section 401(k) of the Code, or
during the following calendar year. The preceding sentence shall not apply if
and to the extent that the General Counsel determines it is not necessary to
qualify any such plan as a cash or deferred arrangement under Section 401(k) of
the Code.
 
     (i) No Option shall be exercisable unless and until the Company (i) obtains
the approval of all regulatory bodies whose approval the General Counsel may
deem necessary or desirable, and (ii) complies with all legal requirements
deemed applicable by the General Counsel.
 
     (j) An Option shall be considered exercised if and when written notice,
signed by the person exercising the Option and stating the number of shares with
respect to which the Option is being exercised, is received by the Secretary on
a properly completed form approved for this purpose by the Committee,
accompanied by full payment of the Option exercise price in one or more of the
forms authorized by the Committee and described
 
                                       B-6
<PAGE>   40
 
in Section 6(b) above for the number of shares to be purchased. No Option may at
any time be exercised with respect to a fractional share.
 
7. CERTAIN CHANGE IN CONTROL, TERMINATION OF EMPLOYMENT AND DISABILITY
PROVISIONS.
 
     Notwithstanding any provision of the Plan to the contrary, any Stock
Incentive which is outstanding but not yet exercisable, vested or payable at the
time of a Change in Control shall become exercisable, vested and payable at that
time; provided that if such Change in Control occurs less than six months after
the date on which such Stock Incentive was granted and if the consideration for
which such Stock Incentive was granted consisted in whole or in part of future
services, then such Stock Incentive shall become exercisable, vested and payable
at the time of such Change in Control only if the Participant agrees in writing
(if requested to do so by the Committee in writing) to remain in the employe of
the Company or a Subsidiary at least through the date which is six months after
the date such Stock Incentive was granted with substantially the same title,
duties, authority, reporting relationships and compensation as on the day
immediately preceding the Change in Control. Any Option affected by the
preceding sentence shall remain exercisable until it expires or terminates
pursuant to its terms and conditions. Subject to the foregoing provisions of
this Section 7, the Committee may at any time, and subject to such terms and
conditions as it may impose:
 
     (a) authorize the holder of an Option to exercise the Option following the
termination of the Participant's employment with the Company and its
Subsidiaries, or following the Participant disability, whether or not the Option
would otherwise be exercisable following such event, provided that in no event
may an Option be exercised after the expiration of its term;
 
     (b) grant Options which become exercisable only in the event of a Change in
Control;
 
     (c) authorize a Stock Bonus Award, Performance Unit Award or Restricted
Stock Award to become non-forfeitable, fully earned and payable upon or
following (i) the termination of the Participant's employment with the Company
and its Subsidiaries, or (ii) the Participant's disability, whether or not the
Award would otherwise become non-forfeitable, fully earned and payable upon or
following such event;
 
     (d) grant Stock Bonus Awards, Performance Unit Awards and Restricted Stock
Awards which become non-forfeitable, fully earned and payable only in the event
of a Change in Control; and
 
     (e) provide in advance or at the time of Change in Control for cash to be
paid in settlement of any Option, Stock Bonus Award, Performance Unit Award or
Restricted Stock Award in the event of a Change in Control, either at the
election of the Participant or at the election of the Committee.
 
8. ADJUSTMENT PROVISIONS.
 
     In the event that any recapitalization, or reclassification, split-up or
consolidation of shares of Common Stock shall be effected, or the outstanding
shares of Common Stock shall be, in connection with a merger or consolidation of
the Company or a sale by the Company of all or a part of its assets, exchanged
for a different number or class of shares of stock or other securities or
property of the Company or any other entity or person, or a record date for
determination of holders of Common Stock entitled to receive a dividend or other
distribution payable in Common Stock or other property (other than normal cash
dividends) shall occur, (a) the number and class of shares or other securities
or property that may be issued or transferred pursuant to Stock Incentives
thereafter granted or that may be optioned or awarded under the Plan to any
Participant, (b) the number and class of shares or other securities or property
that may be issued or transferred under outstanding Stock Incentives, (c) the
purchase price to be paid per share under outstanding and future Stock
Incentives, and (d) the price to be paid per share by the Company or a
Subsidiary for shares or other securities or property issued or transferred
pursuant to Stock Incentives which are subject to a right of the Company or a
Subsidiary to reacquire such shares or other securities or property, shall in
each case be equitably adjusted; provided that with respect to Incentive Stock
Options any such adjustments shall comply with Sections 422 and 424 of the Code.
 
                                       B-7
<PAGE>   41
 
9. EFFECTIVE DATE AND DURATION OF PLAN.
 
     The Plan shall be effective when it is approved by the Board of Directors,
provided that the shareholders of the Company thereafter approve it within one
year of that date. If the Plan is not so approved by shareholders, the Plan (and
any Stock Incentive granted thereunder) shall be null, void and of no force or
effect. If so approved, the Plan shall remain in effect, and Stock Incentives
may be granted, until Stock Incentives have been granted with respect to all
shares authorized to be issued or transferred hereunder or until the Plan is
sooner terminated by the Board of Directors, and shall continue in effect
thereafter with respect to any Stock Incentives outstanding at that time. In no
event shall an Incentive Stock Option be granted under the Plan more than ten
(10) years from the date the Plan is adopted by the Board, or the date the Plan
is approved by the shareholders of the Company, whichever is earlier.
 
10. ADMINISTRATION.
 
     (a) The Plan shall be administered by a committee of the Board consisting
of two or more directors appointed from time to time by the Board. No person
shall be appointed to or shall serve as a member of such committee unless at the
time of such appointment and service he or she shall be a "disinterested
person," as defined in SEC Rule 16b-3. Unless the Board determines otherwise,
the Committee shall be comprised solely of "outside directors" within the
meaning of Section 162(m)(4)(C)(i) of the Code.
 
     (b) The Committee may establish such rules and regulations, not
inconsistent with the provisions of the Plan, as it may deem necessary for the
proper administration of the Plan, and may amend or revoke any rule or
regulation so established. The Committee shall, subject to the provisions of the
Plan, have full power to interpret, administer and construe the Plan and any
instruments issued under the Plan and full authority to make all determinations
and decisions thereunder including without limitation the authority to (i)
select the Participants in the Plan, (ii) determine when Stock Incentives shall
be granted, (iii) determine the number of shares to be made subject to each
Stock Incentive, (iv) determine the type of Stock Incentive to grant, and (v)
determine the terms and conditions of each Stock Incentive, including the
exercise price, in the case of an Option. The interpretation by the Committee of
the terms and provisions of the Plan and any instrument issued thereunder, and
its administration thereof, and all action taken by the Committee, shall be
final, binding, and conclusive on the Company, its stockholders, Subsidiaries,
all Participants and employees, and upon their respective Beneficiaries,
successors and assigns, and upon all other persons claiming under or through any
of them.
 
     (c) Members of the Board of Directors and members of the Committee acting
under this Plan shall be fully protected in relying in good faith upon the
advice of counsel and shall incur no liability except for gross or willful
misconduct in the performance of their duties.
 
11. GENERAL PROVISIONS.
 
     (a) Any provision of the Plan to the contrary notwithstanding, any
derivative security issued under the Plan (within the meaning of paragraph
(a)(2) of SEC Rule 16b-3 as amended in SEC Release No. 34-28869), including
without limitation any Option, shall not be transferable by the Participant
other than by will or the laws of descent and distribution or to a Beneficiary
designated by the Participant. Any purported transfer of a derivative security
to a Beneficiary by a Section 16 Person, and any purported transfer of an
Incentive Stock Option to a Beneficiary, shall be effective only if such
transfer is, in the opinion of the General Counsel, permissible under and
consistent with SEC Rule 16b-3 or Section 422 of the Code, as the case may be.
Notwithstanding the foregoing, a Participant may transfer any Stock Incentive
granted under this Plan, other than an Incentive Stock Option, to members of his
or her immediate family (defined as his or her children, grandchildren and
spouse) or to one or more trusts for the benefit of such family members or
partnerships in which such family members are the only partners if (and only if)
the instrument evidencing such Stock Incentive expressly so provides (or is
amended to so provide) and the Participant does not receive any consideration
for the transfer; provided that any such transferred Stock Incentive shall
continue to be subject to the same terms and conditions that were applicable to
such Stock Incentive immediately prior to its transfer (except that such
transferred Stock Incentive shall not be further transferable by the transferee
inter
 
                                       B-8
<PAGE>   42
 
vivos) and provided, further, that the foregoing provisions of this sentence
shall apply to Section 16 Persons only if the General Counsel determines that
doing so would not jeopardize any exemption from Section 16 of the Exchange Act
(including without limitation SEC Rule 16b-3) for which the Company intends
Section 16 Persons to qualify.
 
     (b) Nothing in this Plan or in any instrument executed pursuant hereto
shall confer upon any person any right to continue in the employment of the
Company or a Subsidiary, or shall affect the right of the Company or a
Subsidiary to terminate the employment of any person at any time with or without
cause.
 
     (c) No shares of Common Stock shall be issued or transferred pursuant to a
Stock Incentive unless and until all legal requirements applicable to the
issuance or transfer of such shares have, in the opinion of the General Counsel,
been satisfied. Any such issuance or transfer shall be contingent upon the
person acquiring the shares giving the Company any assurances the General
Counsel may deem necessary or desirable to assure compliance with all applicable
legal requirements.
 
     (d) No person (individually or as a member of a group) and no Beneficiary
or other person claiming under or through him, shall have any right, title or
interest in or to any shares of Common Stock (i) issued or transferred to, or
acquired by, a trust, (ii) allocated, or (iii) reserved for the purposes of this
Plan, or subject to any Stock Incentive except as to such shares of Common
Stock, if any, as shall have been issued or transferred to him. The Committee
may (but need not) provide at any time or from time to time (including without
limitation upon or in contemplation of a Change in Control) for a number of
shares of Common Stock, equal to the number of such shares subject to Stock
Incentives then outstanding, to be issued or transferred to, or acquired by, a
trust (including but not limited to a grantor trust) for the purpose of
satisfying the Company's obligations under such Stock Incentives, and, unless
prohibited by applicable law, such shares held in trust shall be considered
authorized and issued shares with full dividend and voting rights,
notwithstanding that the Stock Incentives to which such shares relate shall not
have been exercised or may not be exercisable or vested at that time.
 
     (e) The Company and its Subsidiaries may make such provisions as they may
deem appropriate for the withholding of any taxes which they determine they are
required to withhold in connection with any Stock Incentive. Without limiting
the foregoing, the Committee may, subject to such terms and conditions as it may
impose, permit or require any withholding tax obligation arising in connection
with the grant, exercise, vesting, distribution or payment of any Stock
Incentive to be satisfied in whole or in part, with or without the consent of
the Participant, by having the Company withhold all or any part of the shares of
Common Stock that vest or would otherwise be distributed at such time. Any
shares so withheld shall be valued at their Fair Market Value on the date of
such withholding.
 
     (f) Nothing in this Plan is intended to be a substitute for, or shall
preclude or limit the establishment or continuation of, any other plan, practice
or arrangement for the payment of compensation or fringe benefits to directors,
officers or employees generally, or to any class or group of such persons, which
the Company or any Subsidiary now has or may hereafter lawfully put into effect,
including, without limitation, any incentive compensation, retirement, pension,
group insurance, stock purchase, stock bonus or stock option plan.
 
     (g) Any provision of the Plan to the contrary notwithstanding, except to
the extent that the Committee determines otherwise, (i) transactions by and with
respect to Section 16 Persons under the Plan are intended to qualify for any
applicable exemptions provided by SEC Rule 16b-3, and (ii) transactions with
respect to persons whose remuneration would not be deductible by the Company but
for compliance with the provisions of Code Section 162(m)(4)(C) are intended to
comply with the provisions of Code Section 162(m)(4)(C). The Plan is also
intended to give the Committee the authority to award Stock Incentives that
qualify as performance-based compensation under Code Section 162(m)(4)(C) as
well as Stock Incentives that do not so qualify. Every provision of the Plan
shall be administered, interpreted and constructed to carry out the foregoing
intentions and any provision that cannot be so administered, interpreted and
construed shall to that extent be disregarded.
 
     (h) By accepting any benefits under the Plan, each Participant, and each
person claiming under or through him, shall be conclusively deemed to have
indicated his or her acceptance and ratification of, and
 
                                       B-9
<PAGE>   43
 
consent to, all provisions of the Plan and any action or decision under the Plan
by the Company, its agents and employees, and the Board of Directors and the
Committee.
 
     (i) The validity, construction, interpretation and administration of the
Plan and of any determinations or decisions made thereunder, and the rights of
all persons having or claiming to have any interest therein or thereunder, shall
be governed by, and determined exclusively in accordance with, the laws of the
State of Delaware, but without giving effect to the principles of conflicts of
laws thereof. Without limiting the generality of the foregoing, the period
within which any action arising under or in connection with the Plan must be
commenced, shall be governed by the laws of the State of Delaware, without
giving effect to the principles of conflicts of laws thereof, irrespective of
the place where the act or omission complained of took place and of the
residence of any party to such action and irrespective of the place where the
action may be brought.
 
     (j) The use of the masculine gender shall also include within its meaning
the feminine. The use of the singular shall include within its meaning the
plural and vice versa.
 
12. AMENDMENT AND TERMINATION.
 
     The Plan may be amended by the Board of Directors, without shareholder
approval, at any time and in any respect, unless shareholder approval of the
amendment in question is required under Delaware law, the Code (including
without limitation Code Section 422 and Proposed Treasury Regulation Section
1.422A9(b)(iv) thereunder), any applicable exemption from Section 16 of the
Exchange Act (including without limitation SEC Rule 16b-3) for which the Company
intends Section 16 Persons to qualify, any national securities exchange or
system on which the Stock is then listed or reported, by any regulatory body
having jurisdiction with respect to the Plan, or under any other applicable
laws, rules or regulations. The Plan may also be terminated at any time by the
Board of Directors. No amendment or termination of this Plan shall adversely
affect any Stock Incentive granted prior to the date of such amendment or
termination without written consent of the Participant.
