                                    SECTION 1

establishes the Apache Corporation 1990 Stock Incentive Plan (the "Plan") for
certain key employees of the Company. The Plan permits the grant of stock
options to certain key employees of the Company.

1.2 Purposes. The purposes of the Plan are to provide the key management
employees selected for participation in the Plan with added incentives to
continue in the long-term service of the Company and to create in such employees
a more direct interest in the future success of the operations of the Company by
relating incentive compensation to increases in shareholder value, so that the
income of the key management employees is more closely aligned with the income
of the Company's shareholders. The Plan is also designed to attract key
employees and to retain and motivate participating employees by providing an
opportunity for investment in the Company.

1.3 Effective Date. The Effective Date of the Plan (the "Effective Date") shall
be September 19, 1990. This Plan and each option granted hereunder is
conditioned on and shall be of no force or effect until approval of the Plan by
the holders of the shares of voting stock of the Company unless the Company, on
the advice of counsel, determines that shareholder approval is not necessary.

                                    SECTION 2

                               PLAN ADMINISTRATION

The Plan shall also be administered by the Committee. In accordance with the
provisions of the Plan, the Committee shall, in its sole discretion, select the
Participants from among the Eligible Employees, determine the Options to be
granted pursuant to the Plan, the number of shares of Stock to be issued
thereunder and the time at which such Options are to be granted, fix the Option
Price, and establish such other terms and requirements as the Committee may deem
necessary or desirable and consistent with the terms of the Plan. The Committee
shall determine the form or forms of the agreements with Participants which
shall evidence the particular provisions, terms, conditions, rights and duties
of the Company and the Participants with respect to Options granted pursuant to
the Plan, which provisions need not be identical except as may be provided
herein. The Committee may from time to time adopt such rules and regulations for
carrying out the purposes of the Plan as it may deem proper and in the best
interests of the Company. The Committee may correct any defect, supply any
omission or reconcile any inconsistency in the Plan or in any agreement entered
into hereunder in the manner and to the extent it shall deem expedient and it
shall be the sole and final judge of such expediency. No member of the Committee
shall be liable for any action or determination made in good faith. The
determination, interpretations and other actions of the committee pursuant to
the provisions of the Plan shall be binding and conclusive for all purposes and
on all persons.

                                    SECTION 4

                            STOCK SUBJECT TO THE PLAN

4.1 Number of Shares. Two Million Fifty Thousand (2,050,000) shares of Stock are
authorized for issuance under the Plan in accordance with the provisions of the
Plan and subject to such restrictions or other provisions as the Committee may
from time to time deem necessary. This authorization may be increased from time
to time by approval of the Board and by the shareholders of the Company if, in
the opinion of counsel for the Company, such shareholder approval is required.
Shares of Stock which may be issued upon exercise of Options shall be applied to
reduce the maximum number of shares of Stock remaining available for use under
the Plan. The Company shall at all times during

                                      -3-
<PAGE>   7

the term of the Plan and while any Options are outstanding retain as authorized
and unissued Stock, or as treasury Stock, at least the number of shares from
time to time required under the provisions of the Plan, or otherwise assure
itself of its ability to perform its obligations hereunder.

4.2 Other Shares of Stock. Any shares of Stock that are subject to an Option
which expires or for any reason is terminated unexercised, and any shares of
Stock that for any other reason are not issued to an Eligible Employee or are
forfeited shall automatically become available for use under the Plan.

4.3 Adjustments for Stock Split, Stock Dividend, Etc. If the Company shall at
any time increase or decrease the number of its outstanding shares of Stock or
change in any way the rights and privileges of such shares by means of the
payment of a stock dividend or any other distribution upon such shares payable
in Stock, or through a stock split, subdivision, consolidation, combination,
reclassification or recapitalization involving the Stock, then in relation to
the Stock that is affected by one or more of the above events, the numbers,
rights and privileges of the following shall be increased, decreased or changed
in like manner as if they had been issued and outstanding, fully paid in
nonassessable at the time of such occurrence: (i) the shares of Stock as to
which Options may be granted under the Plan; and (ii) the shares of the Stock
then included in each outstanding Option granted hereunder.

4.4 Dividend Payable in Stock of Another Corporation, Etc. If the Company shall
at any time pay or make any dividend or other distribution upon the Stock
payable in securities or other property (except money or Stock), a proportionate
part of such securities or other property shall be set aside and delivered to
any Participant then holding an Option for the particular type of Stock for
which the dividend or other distribution was made, upon exercise thereof. Prior
to the time that any such securities or other property are delivered to a
Participant in accordance with the foregoing, the Company shall be the owner of
such securities or other property and shall have the right to vote the
securities, receive any dividends payable on such securities, and in all other
respects shall be treated as the owner. If securities or other property which
have been set aside by the Company in accordance with this Section are not
delivered to a Participant because an Option is not exercised, then such
securities or other property shall remain the property of the Company and shall
be dealt with by the Company as it shall determine in its sole discretion.

4.5 Other Changes in Stock. In the event there shall be any change, other than
as specified in Sections 4.3 and 4.4, in the number or kind of outstanding
shares of Stock or of any stock or other securities into which the Stock shall
be changed or for which it shall have been exchanged, and if the Committee shall
in its discretion determine that such change equitably requires an adjustment in
the number or kind of shares subject to outstanding Options or which have been
reserved for issuance pursuant to the Plan but are

                                      -4-
<PAGE>   8

not then subject to an Option, then such adjustments shall be made by the
Committee and shall be effective for all purposes of the Plan and on each
outstanding Option that involves the particular type of stock for which a change
was effected.

4.6 Rights to Subscribe. If the Company shall at any time grant to the holders
of its Stock rights to subscribe pro rata for additional shares thereof or for
any other securities of the Company or of any other corporation, there shall be
reserved with respect to the shares then under Option to any Participant of the
particular class of Stock involved the Stock or other securities which the
Participant would have been entitled to subscribe for if immediately prior to
such grant the Participant had exercised his entire Option. If, upon exercise of
any such Option, the Participant subscribes for the additional shares of other
securities, the Option Price shall be increased by the amount of the price that
is payable by the Participant for such Stock or other securities.

4.7 General Adjustment Rules. No adjustment or substitution provided for in this
Section 4 shall require the Company to sell a fractional share of Stock under
any Option, or otherwise issue a fractional share of Stock, and the total
substitution or adjustment with respect to each Option shall be limited by
deleting any fractional share. In the case of any such substitution or
adjustment, the total Option Price for the shares of Stock then subject to the
Option shall remain unchanged but the Option Price per share under each such
Option shall be equitably adjusted by the Committee to reflect the greater or
lesser number of shares of Stock or other securities into which the Stock
subject to the Option may have been changed.

4.8 Determination by the Committee, Etc. Adjustments under this Section 4 shall
be made by the Committee, whose determinations with regard thereto shall be
final and binding upon all parties thereto.

                                    SECTION 5

                          REORGANIZATION OR LIQUIDATION

In the event that the Company is merged or consolidated with another corporation
and the Company is not the surviving corporation, or if all or substantially all
of the assets or more than 20% of the outstanding voting stock of the Company is
acquired by any other corporation, business entity or person, or in case of a
reorganization (other than a reorganization under the United States Bankruptcy
Code) or liquidation of the Company, and if the provisions of Section 9 do not
apply, the Committee, or the board of directors of any corporation assuming the
obligations of the Company, shall, as to the Plan and outstanding Options either
(i) make appropriate provision for the adoption and continuation of the Plan by
the acquiring or successor corporation and for the protection of any such
outstanding Options by the substitution on an equitable basis of appropriate

                                      -5-
<PAGE>   9

stock of the Company or of the merged, consolidated or otherwise reorganized
corporation which will be issuable with respect to the Stock, provided that no
additional benefits shall be conferred upon the Participants holding such
Options as a result of such substitution, and the excess of the aggregate Fair
Market Value of the shares subject to the Options immediately after such
substitution over the Option Price thereof is not more than the excess of the
aggregate Fair Market Value of the shares subject to such Options immediately
before such substitution over the Option Price thereof, or (ii) upon written
notice to the Participants, provide that all unexercised Options must be
exercised within a specified number of days of the date of such notice or they
will be terminated. In the latter event, the Committee shall accelerate the
vesting dates of outstanding Options so that all Options become fully vested and
exercisable prior to any such event.

                                    SECTION 6

                                  PARTICIPATION

Participants in the Plan shall be those Eligible Employees who, in the judgment
of the Committee, are performing, or during the term of their incentive
arrangement will perform, vital services in the management, operation and
development of the Company or an Affiliated Corporation, and significantly
contribute, or are expected to significantly contribute, to the achievement of
long-term corporate economic objectives. Participants may be granted from time
to time one or more Options; provided, however, that the grant of each such
Option shall be separately approved by the Committee, and receipt of one such
Option shall not result in automatic receipt of any other Option. Upon
determination by the Committee that an Option is to be granted to a Participant,
written notice shall be given to such person, specifying the terms, conditions,
rights and duties related thereto. Each Participant shall, if required by the
Committee, enter into an agreement with the Company, in such form as the
Committee shall determine and which is consistent with the provisions of the
Plan, specifying such terms, conditions, rights and duties. Options shall be
deemed to be granted as of the date specified in the grant resolution of the
Committee, which date shall be the date of any related agreement with the
Participant. In the event of any inconsistency between the provisions of the
Plan and any such agreement entered into hereunder, the provisions of the Plan
shall govern.

                                    SECTION 7

                                  STOCK OPTIONS

7.1 Grant of Stock Options. Coincident with or following designation for
participation in the Plan, a Participant may be granted one or more Options. In
no event shall the exercise of one Option affect the right to exercise any other
Option or affect the number

                                      -6-
<PAGE>   10

of shares of Stock for which any other Option may be exercised, except as
provided in subsection 7.2(j).

7.2 Stock Option Agreements. Each Option granted under the Plan shall be
evidenced by a written stock option agreement which shall be entered into by the
Company and the Participant to whom the Option is granted (the "Option Holder"),
and which shall contain the following terms and conditions, as well as such
other terms and conditions, not inconsistent therewith, as the Committee may
consider appropriate in each case.

    (a) Number of Shares. Each stock option agreement shall state that it covers
a specified number of shares of the Stock, as determined by the Committee.

    (b) Price. The price at which each share of Stock covered by an Option may
be purchased shall be determined in each case by the Committee and set forth in
the stock option agreement, but in no event shall the price be less than the
Fair Market Value of the Stock on the date the Option is granted.

    (c) Duration of Options; Employment Required For Exercise. Each stock option
agreement shall state the period of time, determined by the Committee, within
which the Option may be exercised by the Option Holder (the "Option Period").
The Option Period must end, in all cases, not more than ten years from the date
an Option is granted. Except as otherwise provided in Sections 5 and 8 and
subsection 7.2(d)(iv) hereof, each Option granted under the Plan shall become
exercisable in increments such that 25% of the Option will become exercisable on
each of the four subsequent one-year anniversaries of the date the Option is
granted, but each such additional 25% increment shall become exercisable only if
the Option Holder has been continuously employed by the Company from the date
the Option is granted through the date on which each such additional 25%
increment becomes exercisable.

    (d) Termination of Employment, Death, Disability, Etc. Each stock option
agreement shall provide as follows with respect to the exercise of the Option
upon termination of the employment or the death of the Option Holder:

         (i) If the employment of the Option Holder is terminated within the
Option Period for cause, as determined by the Company, the Option shall
thereafter be void for all purposes. As used in this subsection 7.2(d), "cause"
shall mean a gross violation, as determined by the Company, of the Company's
established policies and procedures, provided that the effect of this subsection
7.2(d) (i) shall be limited to determining the consequences of a termination and
that nothing in this subsection 7.2(d) (i) shall restrict or otherwise interfere
with the Company's discretion with respect to the termination of any employee.

                                      -7-
<PAGE>   11

         (ii) If the Option Holder retires from employment by the Company or its
affiliates on or after attaining age 65, the Option may be exercised by the
Option Holder within 36 months following his or her retirement (provided that
such exercise must occur within the Option Period), but not thereafter. In the
event of the Option Holder's death during such 36-month period, each Option may
be exercised by those entitled to do so in the manner referred to in (iv) below.
In any such case, the Option may be exercised only as to the shares as to which
the Option had become exercisable on or before the date of the Option Holder's
retirement.

         (iii) If the Option Holder becomes disabled (as determined pursuant to
the Company's Long-Term Disability Plan), during the Option Period while still
employed, or within the three-month period referred to in (v) below, or within
the 36-month period referred to in (ii) above, the Option may be exercised by
the Option Holder or by his or her guardian or legal representative, within
twelve months following the Option Holder's disability, or within the 36-month
period referred to in (ii) if applicable and if longer (provided that such
exercise must occur within the Option Period), but not thereafter. In the event
of the Option Holder's death during such twelve-month period, each Option may be
exercised by those entitled to do so in the manner referred to in (iv) below. In
any such case, the Option may be exercised only as to the shares as to which the
Option had become exercisable on or before the date of the Option Holder's
disability.

         (iv) In the event of the Option Holder's death while still employed by
the Company, each Option of the deceased Option Holder may be exercised by those
entitled to do so under the Option Holder's will or under the laws of descent
and distribution within twelve months following the Option Holder's death
(provided that in any event such exercise must occur within the Option Period),
but not thereafter, as to all shares of Stock which are subject to such Option,
including each 25% increment of the Option, if any, which has not yet become
exercisable at the time of the Option Holder's death. In the event of the Option
Holder's death within the 36-month period referred to in (ii) above or within
the twelve-month period referred to in (iii) above, each Option of the deceased
Option Holder that is exercisable at the time of death may be exercised by those
entitled to do so under the Option Holder's will or under the laws of descent
and distribution within twelve months following the Option Holder's death or
within the 36-month period referred to in (ii), if applicable and if longer
(provided that in any event such exercise must occur within the Option Period).
The provisions of this paragraph (iv) of subsection 7.2(d) shall be applicable
to each Stock Option Agreement as if set forth therein word for word. Each Stock
Option Agreement executed by the Company prior to the adoption of this provision
shall be deemed amended to include the provisions of this paragraph and all
Options granted pursuant to such Stock Option Agreements shall be exercisable as
provided herein.

                                      -8-
<PAGE>   12

         (v) If the employment of the Option Holder by the Company is terminated
(which for this purpose means that the Option Holder is no longer employed by
the Company or by an Affiliated Corporation) within the Option Period for any
reason other than cause, retirement on or after attaining age 65, disability or
the Option Holder's death, the Option may be exercised by the Option Holder
within three months following the date of such termination (provided that such
exercise must occur within the Option Period), but not thereafter. In any such
case, the Option may be exercised only as to the shares as to which the Option
had become exercisable on or before the date of termination of employment.

         (e) Transferability. Each stock option agreement shall provide that the
Option granted therein is not transferable by the Option Holder except by will
or pursuant to the laws of descent and distribution, and that such Option is
exercisable during the Option Holder's lifetime only by him or her, or in the
event of disability or incapacity, by his or her guardian or legal
representative.

         (f) Agreement to Continue in Employment. Each stock option agreement
shall contain the Option Holder's agreement to remain in the employment of the
Company, at the pleasure of the Company, for a continuous period of at least one
year after the date of such stock option agreement, at the salary rate in effect
on the date of such agreement or at such changed rate as may be fixed, from time
to time, by the Company.

   (g) Exercise, Payments, Etc.

         (i) Each stock option agreement shall provide that the method for
exercising the Option granted therein shall be by delivery to the Corporate
Secretary of the Company of written notice specifying the number of shares with
respect to which such Option is exercised and payment of the Option Price. Such
notice shall be in a form satisfactory to the Committee and shall specify the
particular Option (or portion thereof) which is being exercised and the number
of shares with respect to which the Option is being exercised. The exercise of
the Stock Option shall be deemed effective upon receipt of such notice by the
Corporate Secretary and payment to the Company. If requested by the Company,
such notice shall contain the Option Holder's representation that he or she is
purchasing the Stock for investment purposes only and his or her agreement not
to sell any stock so purchased in any manner that is in violation of the
Securities Act of 1933, as amended, or any applicable state law. Such
restriction, or notice thereof, shall be placed on the certificates representing
the Stock so purchased. The purchase of such Stock shall take place at the
principal offices of the Company upon delivery of such notice, at which time the
purchase price of the Stock shall be paid in full by any of the methods or any
combination of the methods set forth in (iii) below.

                                      -9-
<PAGE>   13

         (ii) Except as referenced below in connection with the Deferred
Delivery Plan, the shares of Stock to which the Participant is entitled as a
result of the exercise of the Option shall be issued by the Company and (A)
delivered by electronic means to an account designated by the Participant, or
(B) delivered to the Participant in the form of a properly executed certificate
or certificates representing such shares of Stock. If Shares of Stock and/or
Depositary Shares are used to pay all or part of the Option Price, the Company
shall issue and deliver to the Participant the additional shares of Stock, in
excess of the Option Price or portion thereof paid using shares of Stock or
Depositary Shares, to which the Participant is entitled as a result of the
Option exercise. If the Participant exercising an Option (x) is eligible for
participation in the Deferred Delivery Plan, (y) pays the Option Price pursuant
to (iii)(C) or (D) below, and (z) has made an irrevocable election at least six
months prior to the Exercise Date as required under the Deferred Delivery Plan,
the income resulting from the Option exercise shall be deferred into the
Participant's Deferred Delivery Plan account and no additional shares of Stock
shall be delivered to the Participant

         (iii) the exercise price shall be paid by any of the following methods
or any combination of the following methods:

              (A) in cash, including the wire transfer of funds to one of the
Company's bank accounts located in the United States, with such bank account to
be designated from time to time by the Company;

              (B) by certified or cashier's check payable to the order of the
Company;

              (C) by delivery to the Company of certificates representing a
number of shares of Stock then owned by the Participant, the Fair Market Value
(as of the Exercise Date) of which is not greater than the Option Price of the
Option being exercised, properly endorsed for transfer to the Company; provided
however, that the shares of Stock used for this purpose must have been owned by
the Participant for a period of at least six months;

              (D) by certification or attestation to the Company of the
Participant's ownership as of the Exercise Date of the number of (1) shares of
Stock and/or (2) Depositary Shares, the Fair Market Value (as of the Exercise
Date) of which is not greater than the Option Price of the Option being
exercised; provided however, that the shares of Stock and/or Depositary Shares
used for this purpose must have been owned by the Participant for a period of at
least six months.

              (E) by delivery to the Company of a properly executed notice of
exercise together with irrevocable instructions to a broker to promptly deliver
to the

                                      -10-
<PAGE>   14

Company, by wire transfer or check as noted in (A) and (B) above, the amount of
the proceeds of the sale of all or a portion of the Stock or of a loan from the
broker to the Option Holder necessary to pay the exercise price.

    (h) Date of Grant. An option shall be considered as having been granted on
the date specified in the grant resolution of the Committee.

    (i)Tax Withholding. Each Stock Option Agreement shall provide that, upon
exercise of the Option, the Participant shall make appropriate arrangements with
the Company to provide for the amount of tax withholding required by Sections
3102 and 3402 or any successor section(s) of the Internal Revenue Code and
applicable state and local income tax laws including, as provided in Section 13
hereof, payment of such taxes (A) through delivery of shares of Stock, (B) by
certification or attestation of shares of Stock or Depositary Shares, or (C) by
withholding shares of Stock otherwise issuable upon exercise of the Option.

    (j) Adjustment of Options. Subject to the provisions of Sections 4, 5, 7, 8
and 12, the Committee may make any adjustment in the number of shares covered
by, or the terms of an outstanding Option and a subsequent granting of an
Option, by amendment or by substitution of an outstanding Option; however,
except as provided in Sections 4, 5, 8 and 12 hereof, the Committee may not
adjust the exercise price of any outstanding Option. Such amendment or
substitution may result in terms and conditions (including the number of shares
covered, vesting schedule or exercise period) that differ from the terms and
conditions of the original Option. The Committee may not, however, adversely
affect the rights of any Participant to previously granted Options without the
consent of such Participant. If such action is effected by amendment, the
effective date of such amendment will be the date of the original grant.

7.3 Shareholder Privileges. No Option Holder shall have any rights as a
shareholder with respect to any shares of Stock covered by an Option until the
Option Holder becomes the holder of record of such Stock, and no adjustments
shall be made for dividends or other distributions or other rights as to which
there is a record date preceding the date such Option Holder becomes the holder
of record of such Stock, except as provided in Section 4.

                                    SECTION 8

                                CHANGE IN CONTROL

8.1 In General. In the event of a change in control of the Company as defined in
Section 8.3, then the Committee may, in its sole discretion, without obtaining
shareholder approval, to the extent permitted in Section 12, take any or all of
the following actions: (a) accelerate the exercise dates of any outstanding
Options or make all such Options fully vested and exercisable; (b) grant a cash
bonus award to any Option Holder in an amount necessary to pay the exercise
price of all or any portion of the Options then held by such Option Holder; (c)
pay cash to any or all Option Holders in exchange for the cancellation of their
outstanding Options in an amount equal to the difference between the exercise
price of such Options and the greater of the tender offer price for the
underlying Stock or the Fair Market Value of the Stock on the date of the
cancellation of the Options; and (d) make any other adjustments or amendments to
the outstanding Options.

8.2 Limitation on Payments. If the provisions of this Section 8 would result in
the receipt by any Participant of a payment within the meaning of Section 280G
of the Internal Revenue Code and the regulations promulgated thereunder and if
the receipt of such payment by any Participant would, in the opinion of
independent tax counsel of recognized standing selected by the Company, result
in the payment by such Participant of any excise tax provided for in Sections
280G and 4999 of the Internal Revenue Code, then the amount of such payment
shall be reduced to the extent required, in the opinion of independent tax
counsel, to prevent the imposition of such excise tax; provided, however, that
the Committee, in its sole discretion, may authorize the payment of all or any
portion of the amount of such reduction to the Participant.

8.3 Definition. For purposes of the Plan, a "change in control" shall mean any
of the events specified in the Company's Income Continuance Plan which
constitute a change in control within the meaning of that Plan.

                                    SECTION 9

                        RIGHTS OF EMPLOYEES, PARTICIPANTS

9.1 Employment. Nothing contained in the Plan or in any Option granted under the
Plan shall confer upon any Participant any right with respect to the
continuation of his or her employment by the Company or any Affiliated
Corporation, or interfere in any way with the right of the Company or any
Affiliated Corporation, subject to the terms of any separate employment
agreement to the contrary, at any time to terminate such employment or to
increase or decrease the compensation of the Participant from the rate in
existence at the time of the grant of an Option. Whether an authorized leave of

                                      -12-
<PAGE>   16

absence, or absence in military or government service, shall constitute a
termination of employment shall be determined by the Committee at the time.

9.2 Nontransferability. No right or interest of any Participant in an Option
granted pursuant to the Plan shall be assignable or transferable during the
lifetime of the Participant, either voluntarily or involuntarily, or subjected
to any lien, directly or indirectly, by operation of law, or otherwise,
including execution, levy, garnishment, attachment, pledge or bankruptcy. In the
event of a Participant's death, a Participant's rights and interests in Options
shall, to the extent provided in Section 7, be transferable by testamentary will
or the laws of descent and distribution, and payment of any amounts due under
the Plan shall be made to, and exercise of any Options may be made by, the
Participant's legal representatives, heirs or legatees. If, in the opinion of
the Committee, a person entitled to payments or to exercise rights with respect
to the Plan is disabled from caring for his affairs because of mental condition,
physical condition or age, payment due such person may be made to, and such
rights shall be exercised by, such person's guardian, conservator or other legal
personal representative upon furnishing the Committee with evidence satisfactory
to the Committee of such status.

                                   SECTION 10

                              GENERAL RESTRICTIONS

10.1 Investment Representations. The Company may require any person to whom an
Option is granted, as a condition of exercising such Option, to give written
assurances in substance and form satisfactory to the Company and its counsel to
the effect that such person is acquiring the Stock subject to the Option for his
own account for investment and not with any present intention of selling or
otherwise distributing the same, and to such other effects as the Company deems
necessary or appropriate in order to comply with Federal and applicable state
securities laws.

10.2 Compliance with Securities Laws. Each Option shall be subject to the
requirement that, if at any time counsel to the Company shall determine that the
listing, registration or qualification of the shares subject to such Option upon
any securities exchange or under any state or federal law, or the consent or
approval of any governmental or regulatory body, is necessary as a condition of,
or in connection with, the issuance or purchase of shares thereunder, such
Option may not be accepted or exercised in whole or in part unless such listing,
registration, qualification, consent or approval shall have been effected or
obtained on conditions acceptable to the Committee. Nothing herein shall be
deemed to require the Company to apply for or to obtain such listing,
registration or qualification.

                                   SECTION 11

                             OTHER EMPLOYEE BENEFITS

The amount of any income deemed to be received by a Participant as a result of
the exercise of an Option shall not constitute "earnings" or "compensation" with
respect to which any other employee benefits of such employee are determined,
including without limitation benefits under any pension, profit sharing, life
insurance or salary continuation plan.

                                   SECTION 12

                  PLAN AMENDMENT, MODIFICATION AND TERMINATION

The Board may at any time terminate, and from time to time may amend or modify
the Plan provided, however, that no amendment or modification may become
effective without approval of the amendment or modification by the shareholders
if shareholder approval is required to enable the Plan to satisfy any applicable
statutory or regulatory requirements, or if the Company, on the advice of
counsel, determines that shareholder approval is otherwise necessary or
desirable.

No amendment, modification or termination of the Plan shall in any manner
adversely affect any Options theretofore granted under the Plan, without the
consent of the Participant holding such Options.

                                   SECTION 13

                                   WITHHOLDING

13.1 Withholding Requirement. The Company's obligations to deliver shares of
Stock upon the exercise of an Option, or to defer income resulting from an
Option exercise into the Deferred Delivery Plan, shall be subject to the
Participant's satisfaction of all applicable federal, state and local income and
other tax withholding requirements.

13.2 Satisfaction of Required Withholding. At the time the Committee grants an
Option, it may, in its sole discretion, grant the Participant an election to pay
all such amounts of required tax withholding, or any part thereof:

    (a) by the delivery to the Company of a number of shares of Stock then owned
by the Participant, the Fair Market Value (as of the Exercise Date) of which is
not greater than the amount required to be withheld, provided that such shares
have been held by the Participant for a period of at least six months;

                                      -14-
<PAGE>   18
    (b) by certification or attestation to the Company of the Participant's
ownership as of the Exercise Date of a number of shares of Stock and/or
Depositary Shares, the Fair Market Value (as of the Exercise Date) of which is
not greater than the amount required to be withheld, provided that such shares
of Stock and/or Depositary Shares have been owned by the Participant for a
period of at least six months; or

    (c) by the Company withholding from the shares of Stock otherwise issuable
to the Participant upon exercise of the Option, a number of shares of Stock, the
Fair Market Value (as of the Exercise Date) of which is not greater than the
amount required to be withheld. Any such elections by Participants to have
shares of Stock withheld for this purpose will be subject to the following
restrictions:

    (i) all elections shall be made on or prior to the Exercise Date; and

   (ii) all elections shall be irrevocable.

13.3 Excess Withholding. At the time the Committee grants an Option, it may, in
its sole discretion, grant the Participant an election to pay additional or
excess amounts of tax withholding, beyond the required amounts and up to the
Participant's marginal tax rate:

    (a) by delivery to the Company of a number of Shares of Stock then owned by
the Participant, the Fair Market Value (as of the Exercise Date) of which is not
greater than such excess withholding amount, provided that such shares of Stock
have been owned by the Participant for a period of at least six month; or

    (b) by certification or attestation to the Company of the Participant's
ownership as of the Exercise Date of a number of shares of Stock and/or
Depositary Shares, the Fair Market Value (as of the Exercise Date) of which is
not greater than such excess withholding amount, provided that such shares of
Stock and/or Depositary Shares have been owned by the Participant for a period
of at least six months.

13.4 Section 16 Requirements. If the Participant is an officer or director of
the Company within the meaning of Section 16 or any successor section(s) of the
1934 Act ("Section 16"), the Participant must satisfy the requirements of such
Section 16 and any applicable rules and regulations thereunder with respect to
the use of shares of Stock and/or Depositary Shares to satisfy such tax
withholding obligation.

14.1 Requirements of Law. The issuance of stock and the payment of cash pursuant
to the Plan shall be subject to all applicable laws, rules and regulations.

director of the Company within the meaning of Section 16, Options granted
hereunder shall be subject to all conditions required under Rule 16b-3, or any

exception from the provisions of Section 16(b) of the 1934 Act available under
that Rule. Such conditions are hereby incorporated herein by reference and shall
be set forth in the agreement with the Participant which describes the Option.

                              DURATION OF THE PLAN
