                              BOARD REPRESENTATION

         3.1. Board Representation Based on Stock Ownership. ONEOK will have the
right to nominate (i) two members to MHR's Board of Directors (or at least 20%
of the total number of members of the Board) so long as the ONEOK Group owns
Common Stock and Preferred Stock that together aggregate at least 20% of the
outstanding Common Stock of MHR on a Fully Diluted Basis or (ii) one member to
MHR's Board of Directors (or at least 10% of the total number of members of the
Board) so long as the ONEOK Group owns Common Stock and Preferred Stock that
together aggregate at least

Magnum
                                       5
<PAGE>

10% (but less than 20%) of the outstanding Common Stock of MHR on a Fully
Diluted Basis. To exercise its right to nominate a member or members to MHR's
Board of Directors, ONEOK will provide written notice to MHR of its nominee or
nominees not less than 90 days prior to the date of MHR's annual meeting of
shareholders (or, if directors are to be elected at a special meeting of
shareholders, not later than ten days after ONEOK has been notified by MHR that
a special meeting will be conducted for such purpose). MHR will use its
reasonable best efforts to facilitate the election of ONEOK's nominees to MHR's
Board of Directors (including without limitation the solicitation of proxies for
their election).

         3.2. Board Representation Following Certain Events. Notwithstanding
Section 3.1 hereof, upon and after the occurrence of any MHR Termination
Default, ONEOK will have the right to nominate, subject to the rights of the TCW
Holders under the 1996 Certificate of Designations (as such terms are defined in
Section 5.12 hereof), that total number of members of the Board of Directors of
MHR (rounded down to the nearest whole director) equal to (i) the then
applicable ONEOK Ownership Percentage multiplied by (ii) the then applicable
number of directors constituting the entire Board (after taking all of ONEOK's
nominees to such Board into account). If following an MHR Termination Default
described in any of clauses (i), (ii) or (iii) of the definition thereof, such
MHR Termination Default is cured (which, in the case of accelerated indebtedness
under clauses (ii) and (iii), shall mean the repayment in full of such
indebtedness) within 180 days after the occurrence of such MHR Termination
Default, the number of ONEOK representatives on MHR's Board of Directors shall
thereafter be determined in accordance with Section 3.1 hereof effective as of
MHR's next annual meeting of shareholders.

         3.3. Board Representation if Board Size Increased. In the event the
size of MHR's Board of Directors is increased above eight members, ONEOK shall
have the right to nominate such number of directors as shall cause its
percentage of directors on the Board immediately after the increase in Board
size to at least equal the percentage of directors to which ONEOK would be
entitled (rounded down to the nearest whole director) based upon the ONEOK
Ownership Percentage. In such event MHR will (i) cause its Board of Directors to
fill the additional directorship or directorships to which ONEOK is entitled,
until the next annual meeting of shareholders of MHR, with a director or
directors designated by ONEOK and (ii) nominate ONEOK's designee or designees to
such additional directorship or directorships at the next annual meeting of
shareholders of MHR.

         3.4. Vacancies. In the event of the death, resignation or removal of a
director of MHR nominated by ONEOK, MHR will (i) cause its Board of Directors to
fill the vacant directorship until the next annual meeting of shareholders of
MHR with a director designated by ONEOK and (ii) nominate ONEOK's designee to
fill such directorship at the next annual meeting of shareholders of MHR;
provided, however, if the vacant directorship results from the removal without
cause of a ONEOK designee on MHR's Board, MHR will nominate another ONEOK
designee to fill such directorship at the next annual meeting of shareholders of
MHR.

         3.5. Approval of ONEOK Representatives. Any nominee of ONEOK to MHR's
Board of Directors (other than executive officers of Parent on the date hereof)
shall be subject to the approval of MHR, which may only withhold such approval
for reasonable business reasons proffered in good faith.

         4.1. Requirement to Vote Stock. Subject to the other provisions of
Article IV of this Agreement, ONEOK will, and will cause each member of the
ONEOK Group to, vote all of its Common Stock and Preferred Stock at every annual
and special meeting of shareholders of MHR and with respect to each matter
submitted to shareholders for approval.

         4.2. Partial Proportionate Voting. Except as otherwise expressly
provided in Section 4.3 hereof, at each annual and special meeting of
shareholders of MHR, ONEOK will, and will cause each member of the ONEOK Group
to, (i) vote up to one-third of the aggregate voting power of its Common Stock
and Preferred Stock of MHR in its sole discretion and (ii) vote the remainder of
its Common Stock and Preferred Stock of MHR in the same proportions as all
shares of voting stock of MHR other than the Common Stock and Preferred Stock
owned by the ONEOK Group are voted. ONEOK will execute such proxy or proxies as
MHR may from time to time reasonably request to effect the proportionate voting
of ONEOK's Common Stock and Preferred Stock in the manner contemplated by this
Section 4.2.

         4.3. Discretionary Voting on Certain Matters. Any member of the ONEOK
Group may vote all of its Common Stock and Preferred Stock in such member's
discretion with respect to (i) a proposed Third Party Change of Control with
respect to MHR (other than a proposed change of control initiated by one or more
members of the ONEOK Group or in which any member of the ONEOK Group is
participating as an acquiring party), (ii) any amendment to MHR's articles of
incorporation and/or (iii) any vote required by the American Stock Exchange
and/or such other national stock exchange upon which any class of MHR's equity
securities are then listed.

         4.4. Relationship to Certificate of Designations. The provisions of
this Article IV shall not diminish the voting rights of the Preferred Stock set
forth in Section 8(b) of the Certificate of Designations relating to the
Preferred Stock.

                                       V.

          OWNERSHIP, PURCHASE AND SALE OF MHR'S STOCK AND SENIOR NOTES

         5.1. Limitation on Purchases of Common Stock. Except as otherwise
expressly provided in Sections 5.2 and 5.3 hereof, ONEOK will not, nor will
ONEOK permit any member of the ONEOK Group to, purchase any shares of Common
Stock of MHR or any securities other than the $50 million in Preferred Stock
purchased on the date hereof that are convertible into, or exercisable or
exchangeable for, Common Stock of MHR.

         5.2. Preemptive Right in Public Offerings. In the event MHR proposes to
issue any equity securities in a registered underwritten public offering
(excluding securities issuable (i) pursuant to MHR's present or future option
plans or other employee benefit plans of any nature whatsoever for MHR's
directors, employees and consultants, (ii) in a business combination on a
registration statement on Form 4 (or any successor form) under the Securities
Act, (iii) pursuant to a transaction governed by Rule 145 under the Securities
Act and/or (iv) as dividends or upon the conversion, exercise or exchange of
other securities), then the ONEOK Group will have the preemptive right to
acquire up to that number of equity securities in the public offering as would
cause the ONEOK Ownership Percentage on a Fully Diluted Basis to be the same
immediately following consummation of such public offering as the ONEOK
Ownership Percentage on a Fully Diluted Basis immediately prior thereto (the
"Preemptive Right Securities"). In the event MHR proposes to issue any equity
securities in a public offering to which the ONEOK Group has the preemptive
right set forth in this Section 5.2, (i) MHR will provide ONEOK with written
notice at least 15 days prior to filing the applicable registration statement
with the Securities and Exchange Commission and (ii) the ONEOK Group may elect
to exercise its preemptive right with respect to such equity offering by
providing written notice of such election to MHR within such 15-day period. If
the ONEOK Group timely elects to exercise its preemptive right by providing such
notice to MHR, the ONEOK Group shall have the right and obligation to purchase
the Preemptive Right Securities at the public offering price at the time of, and
subject to, consummation of the public equity offering.

         5.3. Right to Maintain Proportionate Ownership. In the event MHR issues
any voting Common Stock or preferred stock convertible into voting Common Stock,
and except in those situations expressly covered by Section 5.2 hereof, (i) MHR
will give written notice to ONEOK of each such stock issuance within 45 days
after the end of the calendar quarter during which such issuance occurred and
(ii) the ONEOK Group may, at any time during the 180-day period immediately
following its receipt of such notice, purchase, at MHR's option, in the open
market or from MHR such additional number of shares of its capital stock (which,
if the purchase is from MHR, may at MHR's option be Preferred Stock or voting
Common Stock and shall be sold at such price and terms as are mutually agreed by
MHR and the ONEOK Group) as is necessary to cause the ONEOK Ownership Percentage
immediately following such purchase to equal the ONEOK Ownership Percentage
immediately prior to MHR's issuance of the voting Common Stock or convertible
preferred stock.

         5.4. Effect of Stock Ownership Exceeding 40%. If at any time the ONEOK
Group's ownership of Common Stock of MHR (including Common Stock of MHR issuable
upon conversion of the Preferred Stock) increases or appears to increase above
40% resulting in the ONEOK Group causing or appearing to cause a "Change of
Control" under the Indenture, (i) the applicable putative stock acquisition or
other transaction will for all purposes be void ab initio and of no force or
effect, and MHR will instruct its stock transfer agent not to honor such
putative transaction; (ii) the ONEOK Group will, within five days after the
putative transaction, take all actions necessary to reduce its ownership of
Common Stock of MHR (including Common Stock of MHR issuable upon conversion of
the Preferred Stock) to not more than 40%; and (iii) if notwithstanding MHR's
and the ONEOK Group's compliance with clauses (i) and (ii) of this sentence MHR
is required to make a "Change of Control Offer" under the Indenture, ONEOK will,
or will cause the ONEOK Group to, make available to MHR sufficient financing
upon

Magnum
                                       8
<PAGE>

mutually agreed terms (which terms will be no less favorable to MHR than, at
MHR's option, those terms set forth in the Indenture or such terms as are
commercially available) to repurchase any of the Senior Notes that are then
outstanding and tendered to MHR pursuant to its "Change of Control Offer."
Notwithstanding the immediately preceding sentence, if the ONEOK Group's
ownership interest in MHR increases above 40% as a direct result of a repurchase
of Common Stock by MHR and/or one of its Affiliates, the ONEOK Group will not be
obligated to provide financing to MHR to repurchase the Senior Notes tendered to
MHR.

         5.5. Limitation on Purchases of Senior Notes. ONEOK will not, nor will
it permit any member of the ONEOK Group to, purchase in the aggregate a
principal amount of the Senior Notes that causes the ONEOK Group to own a higher
percentage of the $140 million of Senior Notes originally issued than the ONEOK
Ownership Percentage at the time such purchase of Senior Notes is made.

         5.6. One-Year Prohibition on MHR's Stock Sales. During the one-year
period commencing on the date hereof, and except as otherwise expressly provided
in Section 5.4 hereof, the ONEOK Group will not directly or indirectly sell
(whether directly or indirectly through any derivative or equity-linked
security), pledge, hypothecate, convey or otherwise transfer any shares of the
Preferred Stock.

         5.7. Right of First Purchase on Subsequent Stock Sales. If at any time
after the one-year period commencing on the date hereof, the ONEOK Group
proposes directly or indirectly to sell (whether directly or indirectly through
any derivative or equity-linked security), pledge, hypothecate, convey or
otherwise transfer any shares of the Preferred Stock (or, in the event of a
private placement, Common Stock issuable upon conversion of the Preferred
Stock), to the extent such amount of shares exceeds 10% of the then outstanding
Common Stock of MHR on a Fully Diluted Basis (the "Excess Sale Amount") during
any period of 12 consecutive calendar months, MHR shall have a right of first
purchase to acquire the Excess Sale Amount to be exercised by notice to ONEOK
within ten days after its receipt of written notice of, and upon substantially
the same terms and conditions as, the bona fide third party transaction. If MHR
declines to exercise its right of first purchase and the terms of the proposed
third party transaction are thereafter changed, ONEOK must again provide MHR
with written notice of the proposed transaction and MHR will thereafter again
have a right of first purchase to acquire the Excess Sale Amount to be exercised
by notice to ONEOK within ten days after its receipt of such notice and upon
substantially the same terms and conditions as the revised bona fide third party
transaction.

         5.8. Prohibition on Sales to Significant Shareholders. ONEOK will not,
nor will it permit any member of the ONEOK Group to, directly or indirectly
knowingly sell (whether directly or indirectly through any derivative or
equity-linked security), pledge, hypothecate, convey or otherwise transfer any
shares of the Preferred Stock (or Common Stock issuable upon conversion of the
Preferred Stock) to any prospective transferee or transferees which, together
with any Affiliates or persons acting as a Group therewith, would become the
record or beneficial owner or owners of an amount of capital stock that exceeds
10% of the outstanding Common Stock of MHR on a Fully Diluted Basis after taking
such sale, pledge, hypothecation, conveyance or other transfer into account;
provided, however, this Section 5.8 shall not operate so as to prohibit any
transfers to members of the ONEOK Group. In fulfilling its obligations

Magnum
                                       9
<PAGE>

pursuant to the immediately preceding sentence, ONEOK, in connection with any
transaction not constituting a public offering, shall make reasonable inquiry
of, and obtain appropriate written representations from, the prospective
purchaser or purchasers to determine its then-existing ownership of Common Stock
of MHR (including Preferred Stock and other securities convertible into, or
exercisable or exchangeable for, such Common Stock).

         5.9. Standstill. ONEOK will not, nor will it permit any member of the
ONEOK Group to, at any time effect an MHR Change of Control with respect to MHR
unless such MHR Change of Control is approved by the holders of at least
two-thirds of the outstanding voting securities of MHR other than the ONEOK
Group.

         5.10. Required Repurchase Upon MHR Takeover Event. At any time within
180 days after the occurrence of any MHR Takeover Event with respect to which
the ONEOK Group voted all of its Common Stock and Preferred Stock against such
MHR Takeover Event, ONEOK shall have the right to require MHR to purchase, upon
45 days prior written notice to MHR, any or all Preferred Stock then owned by
the ONEOK Group at a purchase price equal to 108% of the Liquidation Value.

         5.11. Certain Redemption Requirements. Notwithstanding anything to the
contrary in the Certificate of Designations relating to the Preferred Stock, MHR
agrees that, unless MHR redeems all of the Preferred Stock then held by the
ONEOK Group, it shall not redeem shares of the Preferred Stock from the ONEOK
Group if immediately after such redemption ONEOK would not be entitled to
nominate at least one member of MHR's Board of Directors pursuant to its rights
hereunder.

         5.12. TCW Preferred Stock. MHR has previously issued shares of MHR's
1996 Series A Preferred Stock to certain holders (the "TCW Holders") pursuant to
that certain Stock Purchase Agreement dated as of December 6, 1996 (the "TCW
Stock Purchase Agreement") and the Certificate of Voting Powers, Designations,
Preferences, and Relative, Participating, Optional or Other Special Rights of
1996 Series A Convertible Preferred Stock (the "1996 Certificate of
Designations") relating thereto. Upon the occurrence of, or as MHR has notice of
the possibility of the occurrence of, any Voting Event, or any other event which
would constitute a breach of or default under the TCW Stock Purchase Agreement
or the 1996 Certificate of Designations (each, a "TCW Default Event"), MHR shall
immediately (i) provide written notice thereof to ONEOK and (ii) use its
reasonable best efforts to take all such action as is necessary to cure or
obtain from the TCW Holders the appropriate waivers of such TCW Default Event.
MHR shall keep ONEOK informed as to the status and resolution of each TCW
Default Event and shall use its reasonable best efforts to take all such action
toward resolution of each TCW Default Event as ONEOK shall reasonably request.
