                                    SECTION 1

                                  INTRODUCTION

1.1      Establishment. Apache Corporation, a Delaware corporation (hereinafter
referred to, together with its Affiliated Corporations (as defined in subsection
2.1(a)) as the "Company" except where the context otherwise requires), hereby
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.

Plan. The Committee shall be constituted at all times as to permit the Plan to
comply with Rule 16b-3 or any successor rule promulgated under the Securities
Exchange Act of 1934 (the "1934 Act"). Members of the Committee shall be

                                    SECTION 3

                               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 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

                                      -3-

   7


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 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

                                      -4-

   8


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
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

                                      -5-

   9


specified number of days of the date of such notice or they will be terminated.
In the latter event, the Committee shall accelerate the exercise dates of
outstanding Options so that all Options become fully vested 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 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.

                                      -6-

   10


         (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.

                  (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.

                                      -7-

   11


                  (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.

                  (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.

                                      -8-

   12


         (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 (ii) below. A properly executed
certificate or certificates representing the Stock shall be issued by the
Company and delivered to the Option Holder. If certificates representing Stock
are used to pay all or part of the exercise price, separate certificates for the
same number of shares of Stock shall be issued by the Company and delivered to
the Option Holder representing each certificate used to pay the Option Price,
and an additional certificate shall be issued by the Company and delivered to
the Option Holder representing the additional shares, in excess of the Option
Price, to which the Option Holder is entitled as a result of the exercise of the
Option.

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

                           (A)  in cash;

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

                           (C) by delivery to the Company of certificates
representing the number of shares then owned by the Option Holder, the Fair
Market Value of which equals the purchase price of the Stock purchased pursuant
to the Option, properly endorsed for transfer to the Company; provided however,
that shares of Stock used for this purpose must have been held by the Option
Holder for such minimum period of time as may be established from time to time
by the Committee; for purposes of this Plan, the Fair Market Value of any shares
of Stock delivered in payment of the purchase price upon exercise of the Option
shall be the Fair Market Value as of the exercise date; the exercise date shall
be the day of delivery of the certificates for the Stock used as payment of the
Option Price; or

                           (D) by delivery to the Company of a properly executed
notice of exercise together with irrevocable instructions to a broker to deliver
to the Company promptly 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)      Withholding. Each stock option agreement shall provide that,
upon exercise of the Option, the Option Holder shall make appropriate
arrangements with the Company to provide for the Amount of additional
withholding required by Sections 3102 and 3402 of the Internal Revenue Code and
applicable state income tax laws, including payment of such taxes through
delivery of shares of Stock or by withholding Stock to be issued under the
Option, as provided in Section 13.

         (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

                                      -10-

   14


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
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.

                                      -12-

   16


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 compensation deemed to be received by a Participant as a
result of the exercise of an Option shall not constitute "earnings" 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 shall be subject to the Participant's
satisfaction of all applicable federal, state and local income and other tax
withholding requirements.

                                      -13-

13.2     Withholding With Stock. 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 tax withholding, or any part thereof, by electing to transfer to the
Company, or to have the Company withhold from shares otherwise issuable to the
Participant, shares of Stock having a value equal to the amount required to be
withheld or such lesser amount as may be elected by the Participant. All
elections shall be subject to the approval or disapproval of the Committee. The
value of shares of Stock to be withheld shall be based on the Fair Market Value
of the Stock on the date that the amount of tax to be withheld is to be
determined (the "Tax Date"). Any such elections by Participants to have shares
of Stock withheld for this purpose will be subject to the following
restrictions:

         (a)      All elections must be made prior to the Tax Date.

         (b)      All elections shall be irrevocable.

         (c)      If the Participant is an officer or director of the Company
within the meaning of Section 16 of the 1934 Act ("Section 16"), the Participant
must satisfy the requirements of such Section 16 and any applicable Rules
thereunder with respect to the use of Stock to satisfy such tax withholding
obligation.

                                   SECTION 14

                               REQUIREMENTS OF LAW

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.

14.2     Federal Securities Law Requirements. If a Participant is an officer or
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
successor rule promulgated under the 1934 Act, to qualify the Option for 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.

14.3     Governing Law. The Plan and all agreements hereunder shall be construed
in accordance with and governed by the laws of the State of Colorado.

                                   SECTION 15

                              DURATION OF THE PLAN

The Plan shall terminate at such time as may be determined by the Board of
Directors, and no Option shall be granted after such termination. If not sooner
terminated under the preceding sentence, the Plan shall fully cease and expire
at midnight on September 18, 1995. Options outstanding at the time of the Plan
termination may continue to be exercised in accordance with their terms.
