     SECTION 3. PLAN ADMINISTRATION. The Plan shall be administered by the
Committee. The Committee shall have discretionary and final authority to

majority of its members at the time in office and such action may be taken
either by a vote at a meeting or in writing without a meeting. The Committee may
adopt such rules and procedures for the administration of the Plan as are
consistent with the terms hereof and shall keep adequate records of its

Non-Employee Director may elect to have all or any portion of the Director Fees
otherwise payable to him or her for such year deferred for future payment by the
Company in accordance with the provisions of the Plan. The deferral election
made by a Non-Employee Director for a Plan Year under this Plan Section 4(a)
shall specify (i) the portion of the Directors Fees otherwise payable to him or
her for such year that shall be deferred in the form of a dollar amount, (ii)
the portion of the Directors Fees otherwise payable to him or her for such year
that shall be deferred in the form of Units, (iii) the date that the amount
credited to his or her Deferral Account for such year shall be distributed or
commence being distributed (which date shall be at least twelve months after the
end of the Election Period for such year), and (iv) the form of distribution
that shall apply to the amount credited to his or her Deferral Account for such
year. All elections made pursuant to this Plan

                                       -2-
<Page>

Section 4(a) shall be made in writing on a form prescribed by and filed with the
Committee and shall be irrevocable. If a Non-Employee Director fails to make a
deferral election during the Election Period for a Plan Year, his or her
Director Fees for such year shall be paid by the Company to him or her in cash
on the dates such Directors Fees are normally due to be paid under the policies
and practices of the Company with respect thereto.

     (b)  PARTICIPANT ACCOUNTS. For each Plan Year the Company shall establish
and maintain on its books a Deferral Account for each Non-Employee Director who
elects to defer a Director Fees amount for such year pursuant to Plan Section
4(a). Each such Account shall be designated by the name of the Participant for
whom established and the Plan Year to which it relates, and shall be credited in
accordance with the following provisions:

          (1)  The amount of any Director Fees otherwise payable by the Company
     to a Participant during a Plan Year that such Participant has elected to
     defer pursuant to Plan Section 4(a) in the form of a dollar amount shall be
     credited by the Company as a dollar amount to such Participant's Deferral
     Account for that year on the date such amount would otherwise have been
     paid by the Company to such Participant.

          (2)  The amount of any Director Fees otherwise payable by the Company
     to a Participant during a Plan Year that such Participant has elected to
     defer pursuant to Plan Section 4(a) in the form of Units shall be converted
     into Units by dividing such amount by the Fair Market Value per share of
     Common Stock on the date such amount would otherwise have been paid by the
     Company to such Participant, and the number of Units resulting from such
     conversion shall be credited by the Company to such Participant's Deferral
     Account for that year on the date such amount would otherwise have been
     paid by the Company to such Participant.

     (c)  DEFERRAL ACCOUNT ADJUSTMENTS. On the last day of each month, the
amount credited as a dollar amount to each Deferral Account maintained for a
Participant shall be credited with an amount equal to the product obtained by
multiplying one-twelfth (1/12) of the Applicable Percentage by the amount that
has been credited to such Account for the entire period of such month. If a cash
dividend is paid on Common Stock, each Deferral Account then credited with a
Unit shall be credited on the date said dividend is paid with the number of
Units equal to the amount of said dividend per share of Common Stock multiplied
by the number of Units then credited to such Deferral Account, with the product
thereof divided by the Fair Market Value per share of Common Stock on the date
such dividend is paid. If the Company effects a split of its shares of Common
Stock or pays a dividend in the form of shares of Common Stock, or if the
outstanding shares of Common Stock are combined into a smaller number of shares,
the Units credited to a Deferral Account shall be increased or decreased to
reflect proportionately the increase or decrease in the number of outstanding
shares of Common Stock resulting from such split, dividend or combination. In
the event of a reclassification of shares of Common Stock not covered by the
foregoing, or in the event of a liquidation, separation or reorganization
(including, without limitation, a merger, consolidation or sale of assets)
involving the Company, the Board of Directors shall make such adjustments, if
any, to a Deferral Account as the Board of Directors may deem appropriate.

                                       -3-

     (d)  DEFERRAL ACCOUNT PAYMENTS. The dollar amount or Units credited to a
Deferral Account maintained for a Participant (i) shall become distributable to
such Participant pursuant to this Plan Section 4(d) on the first to occur of (1)
the date specified by such Participant in his or her election filed with the
Committee for such Deferral Account during the Election Period for the Plan Year
to which such Deferral Account relates (which date must be at least twelve
months after the end of the Election Period for such year), or (2) the date such
Participant ceases to be a Non-Employee Director, and (ii) shall be distributed
to such Participant either in a single distribution or in approximately equal
annual installments over a period of up to five (5) years, such form of
distribution to be made in accordance with such Participant's election filed
with the Committee for such Deferral Account during the Election Period for the
Plan Year to which such Deferral Account relates. When an amount credited as a
dollar amount to a Participant's Deferral Account becomes distributable, such
amount shall be paid by the Company to such Participant in cash and charged
against such Deferral Account. When Units credited to a Participant's Deferral
Account become distributable, such Units shall be converted into a dollar amount
by multiplying the number of such Units by the Fair Market Value per share of
Common Stock on such date, and the resulting dollar amount shall be paid by the
Company to such Participant in cash and charged against such Deferral Account.
If the amount credited to a Deferral Account is paid in installments over a
period of years, the provisions of Plan Section 4(c) shall continue to apply to
the amount credited to such Deferral Account from time to time.

     (e)  DEATH OF PARTICIPANT. Upon the death of a Participant, the dollar
amount and Units credited to each Deferral Account maintained for such
Participant shall be converted by the Company into cash as provided in Plan
Section 4(d), and shall be distributed by the Company in a single distribution
to the beneficiary or beneficiaries designated by such Participant. Such
designation of beneficiary or beneficiaries shall be made in writing on a form
prescribed by and filed with the Committee, and shall remain in effect until
changed by such Participant by the filing of a new beneficiary designation form
with the Committee. If a Participant fails to so designate a beneficiary, or in
the event all of the designated beneficiaries are individuals who predecease the
Participant, any remaining amount payable under the Plan shall be paid to such
Participant's estate. All distributions under this Plan Section 4(e) shall be
made as soon as practicable following a Participant's death.

     SECTION 5. PLAN AMENDMENT AND TERMINATION. The Board of Directors shall
have the right and power at any time and from time to time to amend the Plan, in
whole or in part, and at any time to terminate the Plan; provided, however, that
no such amendment or termination shall adversely affect the Plan rights or
benefits of a Participant as of the date of such amendment or termination
without his or her consent.

     SECTION 6. GENERAL PROVISIONS.

     (a)  NATURE OF PLAN AND RIGHTS. The Plan is unfunded and maintained by the
Company primarily for the purpose of providing deferred compensation for
Non-Employee Directors. The Units credited and Deferral Accounts maintained
under this Plan are fictional devices used solely for the accounting purposes of
the Plan to determine an amount of money to be paid by the Company to a
Participant pursuant to the Plan, and shall not be deemed or construed to create
a trust fund or security interest of any kind or to grant a property interest of
any kind to any

                                       -4-
<Page>

Participant, designated beneficiary or estate. The amounts credited by the
Company to Deferral Accounts maintained under the Plan are and for all purposes
shall continue to be a part of the general liabilities of the Company, and to
the extent that a Participant, designated beneficiary or estate acquires a right
to receive a cash payment from the Company pursuant to the Plan, such right
shall be no greater than the right of any unsecured general creditor of the
Company.

     (b)  NO CONTINUING RIGHT AS DIRECTOR. Neither the adoption or operation of
the Plan, nor the Plan itself or any document describing or relating to the
Plan, shall confer upon any Participant any right to continue as a director of
the Company or interfere in any way with the rights of the shareholders of the
Company or the Board of Directors to elect and remove directors.

     (c)  SPENDTHRIFT PROVISION. No Account balance or other right or interest
under the Plan of a Participant, designated beneficiary or estate may be
assigned, transferred or alienated, in whole or in part, either directly or by
operation of law, and no such balance, right or interest shall be liable for or
subject to any debt, obligation or liability of such Participant, designated
beneficiary or estate.

     (d)  SEVERABILITY. If any provision of the Plan is held to be illegal or
invalid for any reason, such illegal or invalid provision shall not affect the
remaining provisions of the Plan, and the Plan shall be construed and enforced
as if the illegal or invalid provision had not been included herein.

     (e)  EXPENSES. All expenses associated with the administration of the Plan,
including but not limited to legal and accounting fees, shall be paid by the
Company.

     (f)  BINDING EFFECT. The obligations of the Company under the Plan shall be
binding upon any successor corporation or organization resulting from the
merger, consolidation or other reorganization of the Company, or upon any
successor corporation or organization succeeding to all or substantially all of
the assets and business of the Company. The terms and conditions of the Plan
shall be binding upon each Participant and his or her heirs, legatees,
distributee and legal representatives.

     (g)  GOVERNING LAW. The provisions of the Plan shall be governed by and
construed in accordance with the laws of the State of Texas.

     (h)  CONSTRUCTION. The headings of the Sections and subsections in the Plan
are placed herein for convenience of reference only, and in case of any
conflict, the text of this instrument, rather than such titles or headings,
shall control. When a noun or pronoun is used in the Plan in plural form and
there is only one person or entity within the scope of the word so used, or in
singular form and there is more than one person or entity within the scope of
the word so used, such noun or pronoun shall have a plural or singular meaning
as appropriate under the circumstance.

                       1988 NONQUALIFIED STOCK OPTION PLAN
                           FOR NON-EMPLOYEE DIRECTORS
                                       OF
                             NOBLE AFFILIATES, INC.

              (AS AMENDED AND RESTATED EFFECTIVE JANUARY 29, 2002)

                                    RECITALS

     A.   Effective as of July 26, 1988 (the "Effective Date"), the board of
directors (the "Board of Directors") of Noble Affiliates, Inc., a Delaware
corporation (the "Company"), hereby adopts this 1988 Nonqualified Stock Option
Plan for Non-Employee Directors (the "Plan").

     B.   The purposes of the Plan are to provide to each of the directors of
the Company who is not also either an employee or an officer of the Company
added incentive to continue in the service of the Company and a more direct
interest in the future success of the operations of the Company by granting to
such directors options (the "Options", or individually, the "Option") to
purchase shares of the Company's common stock, $3.33-1/3 par value (the "Common
Stock"), subject to the terms and conditions described below.

                                    ARTICLE I

                                     GENERAL

     1.01 DEFINITIONS. For purposes of this Plan and as used herein,
"non-employee director" shall mean an individual who (a) is now, or hereafter
becomes, a member of the Board of Directors by virtue of an election by the
shareholders of the Company, (b) is neither an employee nor an officer of the
Company and (c) has not elected to decline to participate in the Plan pursuant
to the next succeeding sentence. A director otherwise eligible to participate in
the Plan may make an irrevocable, one-time election, by written notice to the
Company within 30 days after his initial election to the Board of Directors or,
in the case of the directors in office on the Effective Date, prior to
shareholder approval of the Plan, to decline to participate in the Plan. For
purposes of this Plan, "employee" shall mean an individual whose wages are
subject to the withholding of federal income tax under Section 3401 of the
Internal Revenue Code of 1986, as amended from time to time (the "Code"), and
"officer" shall mean an individual elected or appointed by the Board of
Directors or chosen in such other manner as may be prescribed in the By-laws of
the Company to serve as such, except that for the purposes of this Plan, the
Chairman of the Board will not be deemed to be an officer of the Company.

     For purposes of this Plan, and as used herein, the "fair market value" of a
share of Common Stock is the closing sales price on the date in question (or, if
there was no reported sale on such date, on the last preceding day on which any
reported sale occurred) of the Common Stock on the New York Stock Exchange.

<Page>

     1.02 OPTIONS. The Options granted hereunder shall be options that are not
qualified under Section 422A of the Code.

                                   ARTICLE II

                                 ADMINISTRATION

     The Plan shall be administered by the Board of Directors. The Board of
Directors shall have no authority, discretion or power to select the
participants who will receive Options, to set the number of shares to be covered
by each Option, or to set the exercise price or the period within which the
Options may be exercised, or to alter any other terms or conditions specified
herein, except in the sense of administering the Plan subject to the express
provisions of the Plan and except in accordance with Sections 3.02(a) and 6.02
hereof. Subject to the foregoing limitations, the Board of Directors shall have
authority and power to adopt such rules and regulations and to take such action
as it shall consider necessary or advisable for the administration of the Plan,
and to construe, interpret and administer the Plan. The decisions of the Board
of Directors relating to the Plan shall be final and binding upon the Company,
the Holders, as defined hereinafter, and all other persons. No member of the
Board of Directors shall incur any liability by reason of any action or
determination made in good faith with respect to the Plan or any stock option
agreement entered into pursuant to the Plan.

                                   ARTICLE III

                                     OPTIONS

     3.01 PARTICIPATION. Each non-employee director shall be granted Options to
purchase Common Stock under the Plan on the terms and conditions herein
described.

     3.02 STOCK OPTION AGREEMENTS. Each Option granted under the Plan shall be
evidenced by a written stock option agreement, which agreement shall be entered
into by the Company and the non-employee director to whom the Option is granted
(the "Holder"), and which agreement shall include, incorporate or conform to the
following terms and conditions, and such other terms and conditions not
inconsistent therewith or with the terms and conditions of this Plan as the
Board of Directors considers appropriate in each case:

          (a)  OPTION GRANT DATE. Options shall be granted initially as of the
     Effective Date to each non-employee director serving the Company as a
     director on such date. Thereafter, on each July 1 during the term of the
     Plan until and including July 1, 2001, Options shall be granted
     automatically to the incumbent non-employee directors serving the Company
     as directors on such date. Beginning on February 1, 2002, Options shall be
     granted to incumbent non-employee directors each year on February 1 during
     the term of the Plan. Options shall be granted to new non-employee
     directors at the time of their election or appointment. The date of grant
     of an Option pursuant to the Plan shall be referred to hereinafter as the
     "Grant Date" of such Option. Notwithstanding anything herein to the
     contrary, the Board of Directors may revoke, on or prior to July 1, 2001 or
     on or prior to each

                                        2
<Page>

     subsequent February 1, the next automatic grant of Options otherwise
     provided for by the Plan if no options have been granted to employees since
     the preceding Grant Date under the Company's 1982 Stock Option Plan or any
     other employee stock option plan that the Company might adopt hereafter.

          (b)  NUMBER. Each non-employee director serving the Company as a
     director on the Effective Date shall be granted, as of such date, an Option
     to purchase a number of shares of Common Stock equal to the product
     obtained by multiplying (i) the number of completed years such director has
     served the Company as a director by (ii) 500. Thereafter, as of each
     subsequent Grant Date prior to July 1, 2001, each then current non-employee
     director shall be granted an Option to purchase the number of shares of
     Common Stock equal to the nearest number of whole shares determined in
     accordance with the following formula, subject to adjustment in accordance
     with Section 5.02 hereof:

              30,000                        =        Number of Shares of
          --------------                             Common Stock
     Number of Non-Employee Directors

     "Number of Non-Employee Directors" shall mean the number of non-employee
     directors serving the Company as a director on such Grant Date. The formula
     set forth above will not be affected by any decision of the Board of
     Directors to revoke an automatic grant.

          If, on any July 1 during the term of the Plan prior to July 1, 2001,
     fewer than 30,000 shares of Common Stock (subject to adjustment in
     accordance with Section 5.02 hereof) remain available for grant on such
     date, such smaller number will be substituted for 30,000 as the numerator
     in the formula described above to determine the number of shares of Common
     Stock to be subject to each Option to be granted to each non-employee
     director on such date.

          Beginning on July 1, 2001 and on each Grant Date thereafter, each new
     non-employee director shall be granted an Option to purchase 10,000 shares
     of Common Stock, upon election to the Board of Directors as a director, for
     his or her first year of service as a director. On each subsequent Grant
     Date, each then current incumbent non-employee director who has completed
     his or her first year of service as a director shall be granted an Option
     to purchase 5,000 shares of Common Stock.

          (c)  PRICE. The price at which each share of Common Stock covered by
     an Option may be purchased pursuant to this Plan shall be the fair market
     value of the shares on the Grant Date of such Option.

          (d)  OPTION PERIOD. Each Option shall be exercisable from time to time
     over a period (the "Option Period") commencing one year from the Grant Date
     of such Option and ending upon the expiration of ten years from the Grant
     Date, unless terminated sooner pursuant to the provisions described in
     Section 3.02(e) below; provided, however, that any Option granted pursuant
     to the Plan shall become exercisable in full upon the mandatory retirement
     of the Holder as a regular director because of age in accordance with
     Article III of the By-laws of the Company.

                                        3
<Page>

          (e)  TERMINATION OF SERVICE, DEATH, ETC. Each stock option agreement
     shall provide as follows with respect to the exercise of the Option granted
     thereby in the event that the Holder ceases to be a non-employee director
     for the reasons described in this Section 3.02(e):

               (i)   If the Holder ceases to be a director of the Company on
          account of such Holder's (A) fraud or intentional misrepresentation,
          or (B) embezzlement, misappropriation or conversion of assets or
          opportunities of the Company or any direct or indirect majority-owned
          subsidiary of the Company, then the Option shall automatically
          terminate and be of no further force or effect as of the date the
          Holder's directorship terminated;

               (ii)  If the Holder shall die during the Option Period while a
          director of the Company (or during the additional five-year period
          provided by paragraph (iii) of this Section 3.02(e)), the Option may
          be exercised, to the extent that the Holder was entitled to exercise
          it at the date of Holder's death, within five years after such death
          (if otherwise within the Option Period), but not thereafter, by the
          executor or administrator of the estate of the Holder, or by the
          person or persons who shall have acquired the Option directly from the
          Holder by bequest or inheritance or permitted transfer; or

               (iii) If the directorship of a Holder is terminated for any
          reason (other than the circumstances specified in paragraphs (i) and
          (ii) of this Section 3.02(e)) within the Option Period, the Option may
          be exercised, to the extent the Holder was able to do so at the date
          of termination of the directorship, within five years after such
          termination (if otherwise within the Option Period), but not
          thereafter.

          (f)  TRANSFERABILITY. Except as provided in this subsection (f), no
     Option granted under the Plan shall be (i) transferable otherwise than by
     will or the laws of descent and distribution, or (ii) exercisable during
     the lifetime of the Holder by anyone other than the Holder. An Option
     granted under the Plan to a Holder may be transferred by such Holder to a
     permitted transferee (as defined below), provided that (i) there is no
     consideration for such transfer (other than receipt by the Holder of
     interests in an entity that is a permitted transferee); (ii) the Holder (or
     such Holder's estate or representative) shall remain obligated to satisfy
     all income or other tax withholding obligations associated with the
     exercise of such Option; (iii) the Holder shall notify the Company in
     writing that such transfer has occurred and disclose to the Company the
     name and address of the permitted transferee and the relationship of the
     permitted transferee to the Holder; and (iv) such transfer shall be
     effected pursuant to transfer documents in a form approved by the Board of
     Directors. A permitted transferee may not further assign or transfer any
     such transferred Option otherwise than by will or the laws of descent and
     distribution. Following the transfer of an Option to a permitted
     transferee, such Option shall continue to be subject to the same terms and
     conditions that applied to it prior to its transfer by the Holder, except
     that it shall be exercisable by the permitted transferee to whom such
     transfer was made rather than by the transferring Holder. For the purposes
     of the Plan, the term "permitted transferee" means,

                                        4

     with respect to a Holder, (i) any child, stepchild, grandchild, parent,
     stepparent, grandparent, spouse, former spouse, sibling, niece, nephew,
     mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law
     or sister-in-law of the Holder, including adoptive relationships, (ii) any
     person sharing the Holder's household (other than a tenant or an employee),
     (iii) a trust in which the persons described in clauses (i) and (ii) above
     have more than fifty percent of the beneficial interest, (iv) a foundation
     in which the Holder and/or persons described in clauses (i) and (ii) above
     control the management of assets, and (v) any other entity in which the
     Holder and/or persons described in clauses (i) and (ii) above own more than
     fifty percent of the voting interests.

          (g)  AGREEMENT TO CONTINUE IN SERVICE. Each Holder shall agree to
     remain in the continuous service of the Company, at the pleasure of the
     Company's shareholders, at least until the earlier of one year after the
     date of the grant of any Option or the mandatory retirement of the Holder
     as a regular director because of age in accordance with Article III of the
     By-laws of the Company, at the retainer rate and fee schedule then in
     effect or at such changed rate or schedule as the Company from time to time
     may establish.

          (h)  EXERCISE, PAYMENTS, ETC. Each stock option agreement shall
     provide that the method for exercising the Option granted thereby shall be
     by delivery to the President of the Company of, or by sending by United
     States registered or certified mail, postage prepaid, addressed to the
     Company (for the attention of its President) of, written notice signed by
     Holder specifying the number of shares of Common Stock with respect to
     which such Option is being exercised. Such notice shall be accompanied by
     the full amount of the purchase price of such shares. Any such notice shall
     be deemed to be given on the date on which the same was deposited in a
     regularly maintained receptacle for the deposit of United States mail,
     addressed and sent as above-stated. In addition to the foregoing, promptly
     after demand by the Company, the exercising Holder shall pay to the Company
     an amount equal to applicable withholding taxes, if any, due in connection
     with such exercise.

                                   ARTICLE IV

                                    [Deleted]

                                    ARTICLE V

                             AUTHORIZED COMMON STOCK

     5.01 COMMON STOCK. The total number of shares of Common Stock as to which
Options may be granted pursuant to the Plan shall be 550,000, in the aggregate,
except as such number of shares shall be adjusted from and after the Effective
Date in accordance with the provisions of Section 5.02 hereof. If any
outstanding Option under the Plan shall expire or be terminated for any reason
before the end of the Option Period, the shares of Common Stock allocable to the
unexercised portion of such Option may again be subject to the Plan. The Company
shall, at all times during the life of any outstanding Options, retain as
authorized and unissued Common Stock at least the number of shares from time to
time included in the outstanding Options or otherwise assure itself of its
ability to perform its obligation under the Plan.

     5.02 ADJUSTMENTS UPON CHANGES IN COMMON STOCK. In the event the Company
shall effect a split of the Common Stock or dividend payable in Common Stock, or
in the event the outstanding Common Stock shall be combined into a smaller
number of shares, the maximum number of shares as to which Options may be
granted under the Plan shall be increased or decreased proportionately. In the
event that before delivery by the Company of all of the shares of Common Stock
in respect of which any Option has been granted under the Plan, the Company
shall have effected such a split, dividend or combination, the shares still
subject to the Option shall be increased or decreased proportionately and the
purchase price per share shall be increased or decreased proportionately so that
the aggregate purchase price for all the then optioned shares shall remain the
same as immediately prior to such split, dividend or combination.

     In the event of a reclassification of the Common Stock not covered by the
foregoing, or in the event of a liquidation or reorganization, including a
merger, consolidation or sale of assets, the Board of Directors of the Company
shall make such adjustments, if any, as it may deem appropriate in the number,
purchase price and kind of shares covered by the unexercised portions of Options
theretofore granted under the Plan. The provisions of this Section 5.02 shall
only be applicable if, and only to the extent that, the application thereof does
not conflict with any valid governmental statute, regulation or rule.

                                   ARTICLE VI

                               GENERAL PROVISIONS

     6.01 TERMINATION OF THE PLAN. The Plan shall terminate whenever the Board
of Directors adopts a resolution to that effect. If not sooner terminated under
the preceding sentence, the Plan shall wholly cease and expire at the close of
business on July 25, 2006. After termination of the Plan, no Options shall be
granted under this Plan, but the Company shall continue to recognize Options
previously granted.

     6.02 AMENDMENT OF THE PLAN. Subject to the limitations set forth in this
Section 6.02, the Board of Directors may from time to time amend, modify,
suspend or terminate the Plan. No such amendment, modification, suspension or
termination shall (a) impair any Options theretofore granted under the Plan or
deprive any Holder of any shares of Common Stock which he might have acquired
through or as a result of the Plan, or (b) be made without the approval of the
shareholders of the Company where such change would (i) increase the total
number of shares of Common Stock which may be granted under the Plan or decrease
the purchase price under the Plan (other than as provided in Section 5.02
hereof), (ii) materially alter the class of persons eligible to be granted
Options under the Plan, (iii) materially increase the benefits accruing to
Holders under the Plan or (iv) extend the term of the Plan or the Option Period.

     6.03 TREATMENT OF PROCEEDS. Proceeds from the sale of Common Stock pursuant
to Options granted under the Plan shall constitute general funds of the Company.
