                                  ARTICLE VIII

                                  MISCELLANEOUS

     Section 8.1. Injunctive Relief. Each party hereto acknowledges that it
would be impossible to determine the amount of damages that would result from
any breach of any of the provisions of this Agreement and that the remedy at law
for any breach, or threatened breach, of any of such provisions would likely be
inadequate and, accordingly, agrees that each other party shall, in addition to
any other rights or remedies which it may have, be entitled to seek such
equitable and injunctive relief as may be available from any court of competent
jurisdiction to compel specific performance of, or restrain any party from
violating, any of such provisions. In connection with any action or proceeding
for injunctive relief, each party hereto hereby waives the claim or defense that
a remedy at law alone is adequate and agrees, to the maximum extent permitted by
law, to have each provision of this Agreement specifically enforced against him
or it, without the necessity of posting bond or other security against him or
it, and consents to the entry of injunctive relief against him or it enjoining
or restraining any breach or threatened breach of such provisions of this
Agreement.

     Section 8.2. Successors and Assigns. This Agreement shall be binding upon,
shall inure to the benefit of and shall be enforceable by the Company, on the
one hand, and by Parent and the Shareholder, on the other hand, and their
respective successors and

                                       11
<PAGE>

permitted assigns, and no such term or provision is for the benefit of, or
intended to create any obligations to, any other Person.

     Section 8.3. Amendments; Waiver. (a) This Agreement may be amended only by
an agreement in writing executed by the parties hereto.

     (b) Either party may waive in whole or in part any benefit or right
provided to it under this Agreement, such waiver being effective only if
contained in a writing executed by the waiving party. No failure by any party to
insist upon the strict performance of any covenant, duty, agreement or condition
of this Agreement or to exercise any right or remedy consequent upon breach
thereof shall constitute a waiver of any such breach or of any other covenant,
duty, agreement or condition, nor shall any delay or omission of either party to
exercise any right hereunder in any manner impair the exercise of any such right
accruing to it thereafter.

     Section 8.4. Notices. Except as otherwise provided in this Agreement, all
notices, requests, claims, demands, waivers and other communications hereunder
shall be in writing and shall be deemed to have been duly given when delivered
by hand, when delivered personally or by courier, three days after being

and the Board has determined or resolved to redeem or modify (to render

similar agreement) or the Rights or the Rights Agreement (or a substantially
similar agreement) does not, for any other reason, apply to such Clearly
Credible Tender Offer, at the Shareholder's option, Transfers of Subject

Series D Preferred Stock into shares of Common Stock) of the Subject Securities

immediately prior to such Conversion which would have been payable with respect
to all the shares of Common Stock issuable upon Conversion of one share of
Series D Preferred Stock is greater than $0.925 (the "Conversion Threshold") and
(y) such conversion would not have a material adverse effect on the exemptions
from the 1935 Act of the Company or any of its subsidiaries or of Parent, the

has been met. Notwithstanding anything contained in this Section 4.7 to the

authorized stock of the Company into (x) any class or series of the Company's
capital stock ranking equal or prior to the Series D Preferred Stock as to
dividends or as to distributions of assets upon liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, or (y) any class or
series of the Company's capital stock entitled to vote separately as a class on
any matter whatsoever, other than an amendment to the Charter which would have
the effect of modifying the voting powers, designations, preferences, rights and
qualifications, limitations or restrictions of such class or series so as to
affect the holders thereof adversely, or (z) any security convertible into
shares of any class or series described in (x) or (y) above.

                         BOARD REPRESENTATION AND VOTING

     Section 5.1. Directors Designated by the Shareholder. (a) Subsequent to the
Exchange, the Board shall, if requested by the Shareholder, appoint as a
Director the Initial Shareholder Nominee who has been designated by the
Shareholder in writing. The Initial Shareholder Nominee shall be placed in the
class of Directors next standing for election. In the event of a vacancy caused
by the disqualification, removal, resignation or other cessation of service of
the Initial Shareholder Nominee from the Board, the Board shall, if requested by
the Shareholder, elect as a Director (to serve until the Company's immediately
succeeding annual meeting of shareholders) a new Initial Shareholder Nominee who
has been designated by the Shareholder in an additional Initial Shareholder
Nominee Notice that has been provided to the Company at least seven (7) days
prior to the date of a regular meeting of the Board.

     (b) The Shareholder shall provide notice to the Company (the "Initial
Shareholder Nominee Notice") as required by Section 5.1(a) above, which notice
shall contain the following information: (i) the name of the person it has
designated to become a Director (the "Initial Shareholder Nominee"), and (ii)
all information required by Regulation 14A and Schedule 14A under the Exchange
Act with respect to such Initial Shareholder Nominee.

     (c) During the term of this Agreement, the Shareholder shall provide notice
to the Company in writing sixty (60) days prior to each meeting of the Company's
shareholders at which the class of Directors that includes the Initial
Shareholder Nominee is to stand for re-election indicating (i) the name of the
person it has designated to become Director (the "Successor Shareholder Nominee"
and together with Initial Shareholder Nominee, each a "Shareholder Nominee") and
(ii) all information required by Regulation 14A and Schedule 14A under the
Exchange Act with respect to such Successor Shareholder Nominee.

     (d) The Shareholder shall consult with the Company in connection with the
identity of any proposed Shareholder Nominee. In the event the Company is
advised in writ-

                                       12
<PAGE>

ing by its outside counsel that a proposed Shareholder Nominee would not be
qualified under the Company's Charter or By-laws or any applicable statutory or
regulatory standards to serve as a Director, or if the Company otherwise
reasonably objects to the proposed Shareholder Nominee, including without
limitation because such Shareholder Nominee either (i) is a director or officer
of a direct competitor of the Company or (ii) has engaged in any adverse conduct
that would require disclosure under Item 7 of Schedule 14A promulgated under the
Exchange Act, the Shareholder agrees to withdraw such proposed Shareholder
Nominee and nominate a replacement therefor (which replacement would be subject
to the requirements of this Section 5.1(d)). Any such objection by the Company
must be made no later than one (1) month after the Shareholder first informs the
Company of the identity of the proposed Initial Shareholder Nominee; provided,
however, that the Company shall in all cases notify the Shareholder of any such
objection sufficiently in advance of the date on which proxy materials are
mailed by the Company in connection with such election of directors to enable
the Shareholder to propose an alternate Shareholder Nominee pursuant to and in
accordance with the terms of this Agreement.

     (e) During the term of this Agreement the Company agrees to include each
Shareholder Nominee to be added to or retained on the Board pursuant to this
Agreement in the slate of nominees recommended by the Board to the Company's
shareholders for election as Directors and shall use its best efforts to cause
the election or reelection of each such Shareholder Nominee to the Board,
including soliciting proxies in favor of the election of such persons.

     Section 5.2. Resignation of Shareholder Nominee. Unless otherwise agreed by
the Company, the Shareholder shall cause the Shareholder Nominee then serving on
the Board to offer his resignation from the Board immediately upon the
termination of this Agreement pursuant to and in accordance with Section 6.1
hereof.

     Section 5.3. Voting. During the term of this Agreement, Parent and the
Shareholder agree that:

     (a) The Shareholder shall, and shall cause each Shareholder Affiliate to,
be present, in person or by proxy, at all meetings of shareholders of the
Company so that all Securities having voting rights which are Beneficially Owned

of determining the presence of a quorum at such meetings.

     (b) (i) With respect to the election of Directors, the Shareholder shall,
and shall cause each Shareholder Affiliate to, vote all Securities Beneficially
Owned by the Shareholder and any Shareholder Affiliate in favor of the election

Shareholder Nominee) and (ii) with respect to any proposal initiated by a
shareholder of the Company relating

                                       13
<PAGE>

to the redemption of the rights issued pursuant to the Rights Agreement or any
modification of the Rights Agreement (other than nonbinding precatory
resolutions with respect to which subsection (c) hereof shall apply), the
Shareholder shall, and shall cause each member of the Shareholder Group to, vote
all Securities Beneficially Owned by the Shareholder or any member of the
Shareholder Group in accordance with the recommendation of the Board.

     (c) With respect to any proposed amendment to the Charter or By-laws which
would reasonably have the effect of modifying in any way Section 1, Article
Twelfth of the Amended Certificate of Incorporation of the Company dated January
15, 1998, electing that Sections 1145 through 1155 of Title 18 of the Oklahoma
General Corporation Law (the "Control Share Acquisition Statute") shall not
apply to the Company, or would reasonably cause the Company to become subject to
(a) the Control Share Acquisition Statute or (b) any other provisions which are
substantially similar to the Control Share Acquisition Statute, the Shareholder
Group shall have the right to abstain or vote against such amendment.

     (d) During the term of this Agreement, (i) the Shareholder and each member
of the Shareholder Group may vote in their sole discretion those shares of
Common Stock held by them from time to time that were not acquired as a result
of the Conversion of shares of Series D Preferred Stock or otherwise in breach
of this Agreement, and (ii) the Shareholder shall, and shall cause each member
of the Shareholder Group to, vote all other Securities Beneficially Owned by
them that are entitled to vote on such matter in the same proportion (based on
total votes) as all Securities voted on any such other matter are voted by the
shareholders of the Company other than the Shareholder or any member of the
Shareholder Group; provided, however, that the Shareholder and any member of the
Shareholder Group may vote any or all of the Securities Beneficially Owned by
them in their sole discretion with respect to a vote of the Company's
shareholders on any transaction or series of transactions which would, if
consummated, constitute a Change in Control of the Company.

     (e) At all times the Shareholder Group may exercise in its sole discretion
such voting rights as the Series D Preferred Stock may have from time to time
pursuant to the Charter and with respect to an amendment to the Charter which
would have the effect of modifying the voting powers, designations, preferences,
rights and qualifications, limitations or restrictions of such class or series
so as to affect the holders thereof adversely.

                                   ARTICLE VII

                                  MISCELLANEOUS

     Section 7.1. Compliance With Law. Notwithstanding anything to the contrary
in this Agreement, no Transfer of Securities shall be deemed to be required or
permitted pursuant to this Agreement if such Transfer would (a) result in an
adverse effect on the exemptions from the Public Utility Holding Company Act of
1935, as amended, (the "1935 Act") of Parent, the Shareholder or any Shareholder
Affiliate or the Company or any subsidiary of the Company, or (b) require
regulatory approvals which, individually or in the aggregate with respect to
such Transfer, would have a material adverse impact on the Company or any of its
subsidiaries or Parent or the Shareholder or any Shareholder Affiliate.

     Section 7.2. Regulatory Matters. Following the occurrence of any change in
any law, rule, regulation or issuance of any order or interpretation by an
administrative, regulatory or judicial body, if the Company believes that the
Shareholder's regulatory status as modified by such change or issuance would (a)
result in an adverse impact on the exemptions from the 1935 Act of the Company
or any of its subsidiaries, or (b) require regulatory approvals which,
individually or in the aggregate, would have a material adverse impact on the
Company or any of its subsidiaries, then the Company shall have an immediate
right to purchase, upon thirty (30) days' written notice, all, or such lesser
portion as the Company may determine will nullify such unreasonable restriction,
of the Securities Beneficially Owned by the Shareholder Group at a price per
share (assuming conversion of all shares of Series D Preferred Stock into Common
Stock) equal to the Market Price for the Common Stock on the date that such
notice is delivered to the Shareholder; provided that the Shareholder may
Transfer all, or such lesser portion as the Company may determine will nullify
such unreasonable restriction, of the Securities Beneficially Owned by the
Shareholder Group as permitted by Section 4.3

                                       16

hereof and in compliance with Section 7.1 hereof prior to the expiration of such
30-day period.

     Section 7.3. Injunctive Relief. Each party hereto acknowledges that it
would be impossible to determine the amount of damages that would result from
any breach of any of the provisions of this Agreement and that the remedy at law
for any breach, or threatened breach, of any of such provisions would likely be
inadequate and, accordingly, agrees that each other party shall, in addition to
any other rights or remedies which it may have, be entitled to seek such
equitable and injunctive relief as may be available from any court of competent
jurisdiction to compel specific performance of, or restrain any party from
violating, any of such provisions. In connection with any action or proceeding
for injunctive relief, each party hereto hereby waives the claim or defense that
a remedy at law alone is adequate and agrees, to the maximum extent permitted by
law, to have each provision of this Agreement specifically enforced against him
or it, without the necessity of posting bond or other security against him or
it, and consents to the entry of injunctive relief against him or it enjoining
or restraining any breach or threatened breach of such provisions of this
Agreement.

     Section 7.4. Successors and Assigns. This Agreement shall be binding upon,
shall inure to the benefit of and shall be enforceable by the Company, on the
one hand, and by Parent and the Shareholder, on the other hand, and their
respective successors and permitted assigns, and no such term or provision is
for the benefit of, or intended to create any obligations to, any other Person.
Notwithstanding the foregoing, a purchaser of Subject Securities transferred as
permitted by subsections (a)-(c) and (e) of Section 4.3 of this Agreement shall
not be a successor or assign of Parent or Shareholder within the meaning of
Section 7.4.

     Section 7.5. Amendments; Waiver. (a) This Agreement may be amended only by
an agreement in writing executed by the parties hereto. Any approval of an
amendment of this Agreement upon the part of the Company shall require the
approval of a majority of the Independent Directors at a duly convened meeting
thereof or all of the Company's directors by written consent thereto.

     (b) Either party may waive in whole or in part any benefit or right
provided to it under this Agreement, such waiver being effective only if
contained in a writing executed by the waiving party. No failure by any party to
insist upon the strict performance of any covenant, duty, agreement or condition
of this Agreement or to exercise any right or remedy consequent upon breach
thereof shall constitute a waiver of any such breach or of any other covenant,
duty, agreement or condition, nor shall any delay or omission of either party to
exercise any right hereunder in any manner impair the exercise of any such right
accruing to it thereafter. Any waiver of any benefit or right provided to the
Company under this Agreement shall require the approval of a majority of the
Board and a majority of the Independent Directors at a duly convened meeting
thereof or all of the Company's directors by written consent thereto.
