NOBLE AFFILIATES RESTORATION TRUST

      THIS TRUST AGREEMENT, made and executed at Ardmore, Oklahoma, by and
between NOBLE AFFILIATES, INC., a Delaware corporation (the "Company") and
EXCHANGE NATIONAL BANK AND TRUST COMPANY OF ARDMORE, OKLAHOMA (the "Trustee");

                               WITNESSETH THAT:

      WHEREAS, Company has established the nonqualified deferred compensation
plans listed on the attached Appendix A (each a "Plan" and together the "Plans")
for the purpose of providing deferred compensation for a select group of
management or highly compensated employees of Company; and

      WHEREAS, Company has incurred and expects to incur additional liabilities
under the terms of the Plans for the payment of benefits to or with respect to
the employees and former employees of Company who become entitled to benefit
payments from Company pursuant to the provisions of one or more of the Plans
(each a "Plan Participant" and together the "Plan Participants"); and

      WHEREAS, Company desires to establish a trust to be known as the Noble
Affiliates Restoration Trust (the "Trust") and to contribute to the Trust assets
that shall be held therein, subject to the claims of Company's creditors in the
event of Company's insolvency, until paid to Plan Participants or their
beneficiaries who are entitled to Plan benefit payments from Company; and

      WHEREAS, it is the intention of the parties that this Trust shall
constitute an unfunded arrangement and shall not affect the status of the Plans
as unfunded plans maintained for the purpose of providing deferred compensation
for a select group of management or highly compensated employees for purposes of
Title I of the Employee Retirement Income Security Act of 1974, as amended; and

      WHEREAS, it is the intention of Company to make contributions to the Trust
to provide itself with a source of funds to assist it in the meeting of its
liabilities under the Plans;

      NOW, THEREFORE, the parties do hereby establish the Trust and agree that
the Trust shall be comprised, held and disposed of as follows:

      Section 1.  ESTABLISHMENT OF TRUST.

      (a)   Company hereby deposits with Trustee in trust            , which
shall become the principal of the Trust to be held, administered and disposed of
by Trustee as provided in this Trust Agreement.






      (b)   The Trust hereby established shall be irrevocable.

      (c)   The Trust is intended to be a grantor trust, of which Company is the
grantor, within the meaning of subpart E, part I, subchapter J, chapter 1,
subtitle A of the Internal Revenue Code of 1986, as amended, and shall be
construed accordingly.

      (d)   The principal of the Trust, and any earnings thereon shall be held
separate and apart from other funds of Company and shall be used exclusively for
the uses and purposes of Plan Participants, their beneficiaries and Company's
general creditors as herein set forth.  Plan Participants and their
beneficiaries shall have no preferred claim on, or any beneficial ownership
interest in, any assets of the Trust.  Any rights created under the Plans and
this Trust Agreement shall be mere unsecured contractual rights of Plan
Participants and their beneficiaries against Company.  Any assets held by the
Trust will be subject to the claims of Company's general creditors under federal
and state law in the event Company becomes Insolvent as defined in Section 3(a)
herein.

      (e)   Company, in its sole discretion, may at any time, or from time to
time, make additional deposits of cash or other property acceptable to the
Trustee in trust with Trustee to augment the principal to be held, administered
and disposed of by Trustee as provided in this Trust Agreement.  Neither Trustee
nor any Plan Participant or beneficiary shall have any right to compel such
additional deposits.

      (f)   Upon a Change of Control, Company shall, as soon as possible, but in
no event longer than twenty (20) days following the Change of Control, as
defined herein, make an irrevocable contribution to the Trust in an amount that
is sufficient to pay each Plan Participant or beneficiary the benefits to which
Plan Participants or their beneficiaries would be entitled pursuant to the terms
of the Plans as of the date on which the Change of Control occurred.

      Section 2.  PAYMENTS TO PLAN PARTICIPANTS AND THEIR BENEFICIARIES.

      (a)   Company shall deliver to Trustee a schedule (the "Payment Schedule")
that indicates the amounts payable in respect of each Plan Participant (and his
or her beneficiaries), that provides a formula or other instructions acceptable
to Trustee for determining the amounts so payable, the form in which such amount
is to be paid (as provided for or available under the Plans), and the time of
commencement for payment of such amounts.  Except as otherwise provided herein,
Trustee shall make payments to the Plan Participants and their beneficiaries in
accordance with such Payment Schedule.  The Trustee shall make provision for


                                     -2-




the reporting and withholding of any federal, state or local taxes that may be
required to be withheld with respect to the payment of benefits pursuant to the
terms of the Plans and shall pay amounts withheld to the appropriate taxing
authorities or determine that such amounts have been reported, withheld and paid
by Company.

      (b)   The entitlement of a Plan Participant or his or her beneficiaries to
benefits under the Plans shall be determined by Company or such party as it
shall designate under the Plans, and any claim for such benefits shall be
considered and reviewed under the procedures set out in the Plans.

      (c)   Company may make payment of benefits directly to Plan Participants
or their beneficiaries as they become due under the terms of the Plans.  Company
shall notify Trustee of its decision to make payment of benefits directly prior
to the time amounts are payable to a Plan Participant or his or her
beneficiaries.  In addition, if the principal of the Trust, and any earnings
thereon, are not sufficient to make payments of benefits to a Plan Participant
or his or her beneficiaries in accordance with the terms of the Plans, Company
shall make the balance of each such payment as it falls due.  Trustee shall
notify Company where principal and earnings are not sufficient.

      Section 3.  TRUSTEE RESPONSIBILITY REGARDING PAYMENTS TO TRUST
BENEFICIARY WHEN COMPANY IS INSOLVENT.

      (a)   Trustee shall cease payment of benefits to Plan Participants and
their beneficiaries if Company is Insolvent.  Company shall be considered
"Insolvent" for purposes of this Trust Agreement if (i) Company is unable to pay
its debts as they become due, or (ii) Company is subject to a pending proceeding
as a debtor under the United States Bankruptcy Code.

      (b)   At all times during the continuance of this Trust, as provided in
Section 1(d) hereof, the principal and income of the Trust shall be subject to
claims of general creditors of Company under federal and state law as set forth
below.

            (1)   If Company becomes Insolvent, the Board of Directors and the
      Chief Executive Officer of Company shall have the duty to inform Trustee
      in writing of Company's insolvency.  If a person claiming to be a creditor
      of Company alleges in writing to Trustee that Company has become
      Insolvent, Trustee shall determine whether Company is Insolvent and,
      pending such determination, Trustee shall discontinue payment of benefits
      to Plan Participants or their beneficiaries.



                                     -3-




            (2)   Unless Trustee has actual knowledge that Company is Insolvent,
      or has received notice from Company or a person claiming to be a creditor
      alleging that Company is Insolvent, Trustee shall have no duty to inquire
      whether Company is Insolvent.  Trustee may in all events rely on such
      evidence concerning Company's solvency as may be furnished to Trustee and
      that provides Trustee with a reasonable basis for making a determination
      concerning Company's solvency.

            (3)   If at any time Trustee has determined that Company is
      Insolvent, Trustee shall discontinue payments to Plan Participants or
      their beneficiaries and shall hold the assets of the Trust for the benefit
      of Company's general creditors.  Nothing in this Trust Agreement shall in
      any way diminish any rights of Plan Participants or their beneficiaries to
      pursue their rights as general creditors of Company with respect to
      benefits due under the Plans or otherwise.

            (4)   Trustee shall resume the payment of benefits to Plan
      Participants or their beneficiaries in accordance with Section 2 of this
      Trust Agreement only after Trustee has determined that Company is not
      Insolvent (or is no longer Insolvent).

      (c)   Provided that there are sufficient assets, if Trustee discontinues
the payment of benefits from the Trust pursuant to Section 3(b) hereof and
subsequently resumes such payments, the first payment following such
discontinuance shall include the aggregate amount of all payments due to Plan
Participants or their beneficiaries under the terms of the Plans for the period
of such discontinuance, less the aggregate amount of any payments made to Plan
Participants or their beneficiaries by Company in lieu of the payments provided
for hereunder during any such period of discontinuance.

      Section 4.  PAYMENTS TO COMPANY.

      Except as provided in Section 3 hereof, Company shall have no right or
power to direct Trustee to return to Company or to divert to others any of the
Trust assets before all payment of benefits have been made to Plan Participants
and their beneficiaries pursuant to the terms of the Plans.

      Section 5.  INVESTMENT AUTHORITY.

      (a)   Except as otherwise provided in this Trust Agreement, Trustee shall
have all of the rights, powers, duties and obligations with respect to the
investment of the assets of the Trust granted to a trustee under the laws of the
State of


                                     -4-




Oklahoma.  In no event may Trustee invest in securities (including stock or
rights to acquire stock) or obligations issued by Company, other than a de
minimis amount held in common investment vehicles in which Trustee invests.  All
rights associated with assets of the Trust shall be exercised by Trustee or the
person designated by Trustee, and shall in no event be exercisable by or rest
with Plan Participants.

      Section 6.  DISPOSITION OF INCOME.

      During the term of this Trust, all income received by the Trust, net of
expenses and taxes, shall be accumulated and reinvested.

      Section 7.  ACCOUNTING BY TRUSTEE.

      Trustee shall keep accurate and detailed records of all investments,
receipts, disbursements, and all other transactions required to be made,
including such specific records as shall be agreed upon in writing between
Company and Trustee.  Within sixty (60) days following the close of each
calendar year and within sixty (60) days after the removal or resignation of
Trustee, Trustee shall deliver to Company a written account of its
administration of the Trust during such year or during the period from the close
of the last preceding year to the date of such removal or resignation, setting
forth all investments, receipts, disbursements and other transactions effected
by it, including a description of all securities and investments purchased and
sold with the cost or net proceeds of such purchases or sales (accrued interest
paid or receivable being shown separately), and showing all cash, securities and
other property held in the Trust at the end of such year or as of the date of
such removal or resignation, as the case may be.

      Section 8.  RESPONSIBILITY OF TRUSTEE.

      (a)   Trustee shall act with the care, skill, prudence and diligence under
the circumstances then prevailing that a prudent person acting in like capacity
and familiar with such matters would use in the conduct of an enterprise of a
like character and with like aims, provided, however, that Trustee shall incur
no liability to any person for any action taken pursuant to a direction, request
or approval given by Company which is contemplated by, and in conformity with,
the terms of this Trust and is given in writing by Company.  In the event of a
dispute between Company and a party, Trustee may apply to a court of competent
jurisdiction to resolve the dispute.

      (b)   If Trustee undertakes or defends any litigation arising in
connection with this Trust, Company agrees to indemnify Trustee against
Trustee's costs, expenses and liabilities


                                     -5-




(including, without limitation, attorneys' fees and expenses) relating thereto
and to be primarily liable for such payments.  If Company does not pay such
costs, expenses and liabilities in a reasonably timely manner, Trustee may
obtain payment from the Trust.

      (c)   Trustee may consult with legal counsel (who may also be counsel for
Company generally) with respect to any of its duties or obligations hereunder.

      (d)   Trustee may hire agents, accountants, actuaries, investment
advisors, financial consultants or other professionals to assist it in
performing any of its duties or obligations hereunder.

      (e)   Trustee shall have, without exclusion, all powers conferred on
Trustees by applicable law, unless expressly provided otherwise herein,
provided, however, that if an insurance policy is held as an asset of the Trust,
Trustee shall have no power to name a beneficiary of the policy other than the
Trust, to assign the policy (as distinct from conversion of the policy to a
different form) other than to a successor Trustee, or to loan to any person the
proceeds of any borrowing against such policy.

      (f)   Notwithstanding any powers granted to Trustee pursuant to this Trust
Agreement or to applicable law, Trustee shall not have any power that could give
this Trust the objective of carrying on a business and dividing the gains
therefrom, within the meaning of section 301.7701-2 of the Procedure and
Administrative Regulations promulgated pursuant to the Internal Revenue Code.

      Section 9.  COMPENSATION AND EXPENSES OF TRUSTEE.

      For its services as trustee hereunder, Trustee shall be entitled to
reasonable fees commensurate with its duties and responsibilities, taking into
account the value and nature of the Trust and the time and work involved.
Trustee shall be entitled to reimbursement for all reasonable expenses incurred
by Trustee in connection with the administration of the Trust.  Company may pay
such fees and expenses, but if not so paid, such fees and expenses shall be paid
from the assets of the Trust.

      Section 10.  RESIGNATION AND REMOVAL OF TRUSTEE.

      (a)   Trustee may resign at any time by written notice to Company, which
shall be effective sixty (60) days after receipt of such notice unless Company
and Trustee agree otherwise.



                                     -6-




      (b)   Trustee may be removed by Company on sixty (60) days notice or upon
shorter notice accepted by Trustee.

      (c)   Notwithstanding any other provision of this Trust Agreement, Trustee
may not be removed by Company during the two (2) year period immediately
following a Change of Control, as defined herein.

      (d)   If Trustee resigns within two (2) years after a Change of Control,
as defined herein, Company shall apply to a court of competent jurisdiction for
the appointment of a successor Trustee or for instructions.

      (e)   Upon resignation or removal of Trustee and appointment of a
successor Trustee, all assets shall subsequently be transferred to the successor
Trustee.  The transfer shall be completed within seventy-five (75) days after
receipt of notice of resignation, removal or transfer, unless Company extends
the time limit.

      (f)   If Trustee resigns or is removed, a successor shall be appointed, in
accordance with Section 11 hereof, by the effective date of resignation or
removal under paragraph (a) or (b) of this section.  If no such appointment has
been made, Trustee may apply to a court of competent jurisdiction for
appointment of a successor or for instructions.  All expenses of Trustee in
connection with the proceeding shall be allowed as administrative expenses of
the Trust.

      Section 11.  APPOINTMENT OF SUCCESSOR.

      If Trustee resigns or is removed in accordance with Section 10(a) or (b)
hereof, Company may appoint any third party, such as a bank trust department or
other party that may be granted corporate trustee powers under state law, as a
successor to replace Trustee upon resignation or removal.  The appointment shall
be effective when accepted in writing by the new Trustee, who shall have all of
the rights and powers of the former Trustee, including ownership rights in the
Trust assets.  The former Trustee shall execute any instrument necessary or
reasonably requested by Company or the successor Trustee to evidence the
transfer.

      Section 12.  AMENDMENT OR TERMINATION.

      (a)   This Trust Agreement may be amended by a written instrument executed
by Trustee and Company.  Notwithstanding the foregoing, no such amendment shall
conflict with the terms of the Plans or shall make the Trust revocable.



                                     -7-




      (b)   The Trust shall not terminate until the date on which Plan
Participants and their beneficiaries are no longer entitled to benefits pursuant
to the terms of the Plans.  Upon termination of the Trust any assets remaining
in the Trust shall be returned to Company.

      (c)   Upon written approval of all Plan Participants and beneficiaries of
deceased Plan Participants, Company may terminate this Trust prior to the time
all benefit payments under the Plans have been made to Plan Participants and
their beneficiaries.  All assets in the Trust at termination shall be returned
to Company.

      (d)   Sections 1(f), 10(c), 10(d) and 12(a) through (d) of this Trust
Agreement may not be amended by Company for two (2) years following a Change of
Control, as defined herein.

      Section 13.  MISCELLANEOUS.

ineffective to the extent of any such prohibition, without invalidating the
remaining provisions hereof.
