March 31, 1998
                          NEWS FOR IMMEDIATE RELEASE

  Gothic Energy Corporation Announces Recapitalization Plan and Hiring of New
                                Senior Officers

Tulsa, Oklahoma - Gothic Energy Corporation announced today a plan of
recapitalization for its existing debt and preferred securities.  The plan
includes (i) the reorganization of Gothic through the creation of a wholly-owned
subsidiary, Gothic Production Company ("Gothic Production"), to hold Gothic's
oil and gas assets, (ii) a series of transactions with Chesapeake Energy
Corporation ("Chesapeake") which include the sale of certain of the Company's
Arkoma assets for $20 million, the formation of a five year participation
agreement involving the development of all of the Company's existing acreage in
the Mid-Continent, and the issuance by Gothic of $50 million of Series B
Preferred Stock to Chesapeake (together, the "Chesapeake Transactions"), (iii)
the issuance by Gothic and Gothic Production of approximately $295 million of
new senior notes, and (iv) the repayment and/or refinancing of substantially all
of Gothic's currently existing debt and preferred securities (together, the
"Recapitalization").  The Recapitalization is expected to be completed by late
April.

In addition, Gothic announced that it had successfully completed a consent
solicitation with holders of its 12 1/4% Senior Notes due 2004 and its Series A
Preferred Stock whereby those holders agreed to certain amendments that will
facilitate the Recapitalization.

The Company also announced that it had hired Steven P. Ensz as Vice President -
Finance and Chief Financial Officer and John P. Coughlon as Senior Geologist.
Mr. Ensz, who was most recently with Anglo-Suisse, Inc. ("Anglo-Suisse"), has
extensive experience in the oil and gas business and is a certified public
accountant.  Mr. Coughlon, most recently with Amoco Production Company
("Amoco"), was actively involved in the exploitation of the assets recently
acquired by Gothic from Amoco and has extensive knowledge of the Company's Mid-
Continent area oil and gas producing properties.

The Recapitalization
- --------------------

In connection with the Recapitalization, Gothic and Gothic Production currently
intend to issue approximately $295 million of new senior notes in private
placement transactions subject to rule 144A.  Such securities will not be
registered under the Securities Act of 1933, as amended, and will not be able to
be resold in the United States by the purchasers absent such registration or an
applicable exemption.  The proceeds from this intended issuance, when combined
with the $70 million of proceeds from the Chesapeake Transactions, is expected
to allow Gothic to repay and/or refinance all of its currently outstanding bank
and other debt and preferred securities.

Chesapeake Transactions
- -----------------------

The Chesapeake Transactions, which are contingent upon the completion of the
Recapitalization, provide for the following:

 .  the formation of a participation agreement which provides Chesapeake the
   right, for a five year period, to participate in up to 50% of the Company's
   development and exploration projects on all of its existing acreage and to
   act as operator during the drilling and completion in any well which Gothic
   operates and in which Chesapeake chooses to participate;

 .  the sale of 50% of Gothic's oil and gas assets in the Arkoma Basin for $20
   million;

 .  the purchase by Chesapeake of $50 million of Gothic's newly-issued Series B
   Preferred Stock due 2008, with related warrants to purchase 2,439,246 shares
   of Gothic's common stock with an exercise price of $0.01 per share; and

 .  the right for Chesapeake to designate for election one member to Gothic's
   Board of Directors.

3/31/98 News Release

Chesapeake is an independent oil and natural gas producer headquartered in
Oklahoma City, Oklahoma.  Chesapeake's operations are focused on exploratory and
development drilling and producing property and corporate acquisitions in major
onshore producing areas of the United States and Canada.

New Senior Officers
- -------------------

Steven P. Ensz joined the Company in March from a position as Vice President -
Finance at Anglo-Suisse, a Houston-based developer of international oil and
natural gas projects.  Prior to joining Anglo-Suisse in 1991, Mr. Ensz acted as
an independent financial consultant to the oil and gas industry and was
President of Waterford Energy, a privately-held oil and natural gas company with
operations in the Mid-Continent, from 1983 to 1990.  Prior to joining Waterford,
Mr. Ensz was a partner at Oak, Simon & Ott, a public accounting firm.  Mr. Ensz
received a Bachelor of Business Adminstration degree in accounting from Wichita
State University and is a certified public accountant.

John P. Coughlon also joined the Company in March.  Previously, Mr. Coughlon was
a senior staff geologist at Amoco and was actively involved in the development
of the assets purchased by Gothic in January.  Prior to joining Amoco in 1994,
Mr. Coughlon worked as a geologist with Tower Energy, NICOR Oil and Gas and
Mobil Oil Corporation.  Mr. Coughlon has over 14 years of experience in the Mid-
Continent region and extensive knowledge of many of the areas in which the
Company is actively involved.  He received a Bachelor of Science in Geology from
the University of Iowa and a Master of Science in Geology from the University of
Texas at El Paso.

Management Comments
- -------------------

Mike Paulk, President and founder of Gothic, stated, "We believe the
Recapitalization will provide Gothic with the long-term capital it needs to
provide a foundation for its continued growth.  We believe that the
Recapitalization will allow the Company to direct its resources fully to our two
main objectives - developing our existing asset base and maintaining our low
production cost. The Chesapeake Transactions create for Gothic a partnership
with an active and knowledgeable drilling partner that should provide support
for the successful implementation of the Company's Mid-Continent drilling
program. Further, the Chesapeake Transactions provide the base investment for
the Recapitalization, which should provide the Company with the financial
flexibility to pursue its objectives."

"The addition of two new members to the management team of the quality of Steve
Ensz and John Coughlon will provide the Company with the additional skills
needed to appropriately exploit an asset base that has grown by over 300% since
mid-1997.  Gothic now has the necessary group of employees, all with significant
experience in the areas in which the Company's assets are concentrated, to fully
exploit the opportunities before it."

                        REPRESENTATIONS AND WARRANTIES
                        ------------------------------

     Section 3.1.  Representations and Warranties of the Company.  The Company
represents and warrants to the Purchaser and Purchaser's Parent as of the date
hereof and as of the Time of Purchase as follows:

            (a) The Information provided to the Purchaser will not, at the 
Time of Purchase, contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

            (b) The audited consolidated financial statements of the Company and
its Subsidiaries, together with related notes and schedules thereto, included in
the Exchange Act Filings fairly represent in all material respects the financial
condition of the Company and its Subsidiaries as of the dates indicated and the
results of operations and cash flows for the periods therein specified in
conformity with generally accepted accounting principles consistently applied
throughout the periods involved (except as otherwise stated therein).  Coopers &
Lybrand, which reported upon the audited financial statements and schedules
included in the Exchange Act Filings, is an independent public accounting firm
as required by the Act and the rules and regulations thereunder.

            (c) The Company is a corporation duly organized, validly existing 
and in good standing under the laws of the State of Oklahoma. Each of the
Company's Subsidiaries, including Gothic Production Corporation, a wholly-owned
Subsidiary of the Company formed for the purpose of becoming the primary
operating Subsidiary of the Company and owning substantially all of the
Company's assets, is a corporation duly incorporated or organized, validly
existing and in good standing under the laws of their respective jurisdictions
of incorporation. Each of the Company and its Subsidiaries is duly qualified and
in good standing as a foreign corporation, and is authorized to do business, in
each jurisdiction in which the ownership or leasing of any property or the
nature of its business makes such qualification necessary and in which the
failure so to qualify would have a Material Adverse Effect.

            (d) The authorized capital stock of the Company consists of
100,500,000 shares, of which 100,000,000 shares, par value $.01 per share, are
designated "Common Stock" and 500,000 shares, par value $.05 per share, are
designated "Preferred Stock."  The Company has 16,261,640 shares of Common Stock
issued and outstanding and 37,000 shares of Senior Redeemable Preferred Stock,
Series A, issued and outstanding.  All of the issued and outstanding shares of
capital stock of the Company and its Subsidiaries are validly issued, fully paid
and non-

                                      -6-
<PAGE>
 
assessable and were not issued in violation of any preemptive or similar rights.
The Company has no Subsidiaries other than those listed on Schedule 3.1(d)(A)
attached hereto.  All of the capital stock of the Company's subsidiaries is
owned by the Company, free and clear of any Liens.  Except as described on
Schedule 3.1(d)(B) attached hereto, there are no outstanding securities,
subscriptions, options, warrants, rights, convertible securities or other
binding agreements or commitments of any character obligating the Company or its
Subsidiaries to issue any securities other than the Common Stock Warrant.
Except as described in the Information, no Person other than the Purchaser has
any rights to the registration of capital stock or other securities of the
Company, under the Act or otherwise.  Except as disclosed in the Information,
there is no agreement, understanding or arrangement among the Company or its
Subsidiaries and its respective stockholders or any other person relating to (i)
the ownership or disposition of any capital stock of the Company or any of its
Subsidiaries, (ii) the election of directors of the Company or any of its
Subsidiaries or (iii) the governance of the Company's or any such Subsidiary's
affairs; and no such agreements, arrangements or understandings will be breached
or violated as a result of the execution and delivery of, or the consummation of
the transactions contemplated by, this Agreement or the other Basic Documents.
The Company has reserved for issuance upon exercise of the Common Stock Warrant
shares of Common Stock sufficient in number for the full exercise thereof at the
initial exercise price, and the Warrant Shares will, upon issuance, be fully
paid, non-assessable and free of preemptive rights and will not be subject to
any restrictions on the transfer thereof, except for such restrictions set forth
herein and in the Warrant Agreement and under the Act.  Except as set forth on
Schedule 3.1(d)(C) attached hereto, there are no outstanding registration rights
with respect to any shares of capital stock of the Company.

            (e) The Certificate of Designation has been duly authorized by the
Company, its board of directors and all required stockholder action and when
executed and delivered by the Company and filed with the Secretary of State of
the State of Oklahoma will constitute a valid and legally binding agreement of
the Company, enforceable against it in accordance with its terms, except that
the enforcement thereof may be subject to bankruptcy, insolvency,
reorganization, fraudulent conveyance, moratorium or similar laws now or
hereafter in effect relating to creditors' rights and remedies generally and
general principles of equity and the discretion of the court before which any
proceeding therefor may be brought.  The Certificate of Incorporation of the
Company, by virtue of the filing of the Certificate of Designation, sets forth
the rights, preferences and priorities of the Preferred Stock.

            (f) This Agreement has been duly authorized by the Company and, when
executed and delivered by the Company (assuming the due authorization, execution
and delivery by the Purchaser), will constitute a valid and legally binding
agreement of the Company, enforceable against it in accordance with its terms,
except as such enforceability may be limited by (i) bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium or similar laws

                                      -7-

now or hereafter in effect relating to creditors' rights and remedies generally
and (ii) general equitable principles whether asserted in an action at law or in
equity, and that such enforceability may be subject to the discretion of the
court before which any proceedings therefor may be brought.

            (g) The Common Stock Warrant and the Warrant Shares have been duly
authorized by the Company and, when the Common Stock Warrant is executed by the
Company and issued by the Company to the Purchaser in accordance with the terms
of this Agreement, the Common Stock Warrant will constitute the valid and
legally binding obligation of the Company enforceable in accordance with its
terms, except as such enforceability may be limited by (i) bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium or similar laws
now or hereafter in effect relating to creditors' rights and remedies generally
and (ii) general equitable principles, whether asserted in an action at law or
in equity, and that such enforceability may be subject to the discretion of the
court before which any proceedings therefor may be brought.

            (h) The Company has all requisite corporate power and authority to 
(i) execute, deliver and perform its obligations under this Agreement and each
of the other Basic Documents, (ii) execute, deliver and perform its obligations
under all other agreements and instruments executed and delivered by the Company
pursuant to or in connection with this Agreement and each of the other Basic
Documents and (iii) issue the Securities pursuant hereto in the manner and for
the purpose contemplated by this Agreement. The execution and delivery by the
Company of this Agreement and each of the other Basic Documents, and the
consummation of the transactions contemplated hereby and thereby, have been duly
and validly authorized by the Company.

            (i) Except as set forth in the Memorandum and the Exchange Act
Filings, subsequent to the date as of which information is given in the Exchange
Act Filings and immediately prior to the Time of Purchase, there has not been
(i) any event or condition that has had or that would reasonably be expected to
have a Material Adverse Effect on the Company and its Subsidiaries, taken as a
whole, (ii) any transaction entered into by the Company or any Subsidiary, other
than in the ordinary course of business, that is material to the Company and its
Subsidiaries, taken as a whole, or (iii) any dividend or distribution of any
kind declared, paid or made by the Company on its Common Stock that has not been
approved by the Purchaser in writing.

            (j) There is no action, suit, investigation or proceeding,
governmental or otherwise, pending or, to the best knowledge of the Company,
threatened to which the Company or any of its Subsidiaries is or would be a
party or of which the properties of the Company or its Subsidiaries are or may
be subject, that (i) seeks to restrain, enjoin, prevent the consummation of or
otherwise challenge the issuance and sale of the Securities by the Company or
any of the other

                                      -8-
<PAGE>
 
transactions contemplated by this Agreement, (ii) questions the legality or
validity of any such transactions or seeks to recover damages or obtain other
relief in connection with any such transactions or (iii) would have a Material
Adverse Effect on the Company and its Subsidiaries, taken as a whole.

            (k) The execution, delivery and performance by the Company of this
Agreement and the other Basic Documents, and the issuance and sale by the
Company of the Securities and the execution, delivery and performance by the
Company of all other agreements and instruments to be executed and delivered by
the Company pursuant hereto or thereto or in connection herewith or therewith,
and compliance by the Company with the terms and provisions hereof and thereof,
do not and will not (i) violate any provision of any law, rule or regulation
(including, without limitation, Regulation G, T, U or X of the Board of
Governors of the Federal Reserve System), order, writ, judgment, decree,
determination or award presently in effect or in effect at the Time of Purchase
having applicability to the Company or any of its Subsidiaries, (ii) conflict
with, result in a breach of or constitute a default under the certificate of
incorporation or by-laws of the Company or any of its Subsidiaries, or, as of
the Time of Purchase, any indenture or loan or credit agreement, or any other
agreement or instrument to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries or any of their
respective properties may be bound or affected, or (iii) except as contemplated
by this Agreement and the other Basic Documents, result in, or require the
creation or imposition of, any Lien upon or with respect to any of the
properties now owned or hereafter acquired by the Company or any of its
Subsidiaries, except, in the case of clause (i), (ii) or (iii) of this Section
3.1(k), where such violation, conflict, default or creation or imposition of any
Lien would not (individually or in the aggregate) have a Material Adverse Effect
on the Company and its Subsidiaries, taken as a whole.

            (l) Each agreement or instrument executed and delivered by the 
Company in connection with this Agreement has been duly and validly authorized,
executed and delivered by the Company and constitutes or will constitute a
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms, except as such enforceability may be
limited by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or similar laws now or hereafter in effect relating to creditors'
rights and remedies generally and (ii) general equitable principles, whether
asserted in an action at law or in equity, and that such enforceability may be
subject to the discretion of the court before which any proceedings therefor may
be brought.

            (m) Immediately after giving effect to the consummation of the
transactions contemplated by this Agreement, neither the Company nor any of its
Subsidiaries (i) will be in violation of its respective certificate of
incorporation or by-laws, (ii) will be in default (nor will an event occur which
with notice or passage of time or both would constitute such a default)

                                      -9-
<PAGE>
 
under or in violation of any indenture or loan or credit agreement or any other
material agreement or instrument to which it is a party or by which it or any of
its properties may be bound or affected, (iii) will be in violation of any order
of any court, arbitrator or governmental body or subject to or party to any
order of any court or governmental authority arising out of any action, suit or
proceeding under any statute or other law respecting antitrust, monopoly,
restraint of trade, unfair competition or similar matters or (iv) will have
violated or be in violation of any such statute, rule or regulation of any
governmental authority, which default or violation (individually or in the
aggregate) would (x) affect the legality, validity or enforceability of this
Agreement or any of the other Basic Documents or (y) have a Material Adverse
Effect on the Company and its Subsidiaries, taken as a whole.

            (n) No authorization, consent, approval, license, qualification or
formal exemption from, nor any filing, declaration or registration with, any
court, governmental agency or regulatory authority or any securities exchange is
required in connection with the execution, delivery or performance by the
Company or any of its Subsidiaries (to the extent they are a party thereto) of
this Agreement or any of the other Basic Documents, except (i) as may be
required under state securities or "blue sky" laws or the laws of any foreign
jurisdiction in connection with the offer and sale of the Securities or (ii) as
would not (individually or in the aggregate) have a Material Adverse Effect on
the Company and its Subsidiaries, taken as a whole or (iii) as would not have a
material adverse effect on the value of the Purchaser's rights under the Basic
Documents.  All such authorizations, consents, approvals, licenses,
qualifications, exemptions, filings, declarations and registrations which are
required to have been obtained or made as of the Time of Purchase have been
obtained or made, as the case may be, and are in full force and effect and not
the subject of any pending or, to the knowledge of the Company, threatened
attack by appeal, direct proceeding or otherwise.

            (o) The Company and each of its Subsidiaries has good and valid 
title to, or valid and enforceable leasehold interests in, all properties and
assets identified in the Memorandum or the Exchange Act Filings as owned by each
of them which are material to the business of the Company and its Subsidiaries,
taken as a whole, free and clear of all Liens, except such Liens as are
described in the Memorandum or the Exchange Act Filings or on Schedule 3.1(o)
hereto. All of the leases material to the business of the Company and the
Subsidiaries, taken as a whole, and under which the Company or any Subsidiary
holds properties described in the Memorandum or the Exchange Act Filings, are
valid and binding as leased by them, with such exceptions as are not material
and do not materially interfere with the use made and proposed to be made of
such properties by the Company and its Subsidiaries.

            (p) All tax returns required to be filed by the Company or any of 
its Subsidiaries in any jurisdiction (including foreign jurisdictions) have been
so filed and all taxes, assessments, fees and other charges including, without
limitation, withholding taxes, penalties,

                                      -10-
<PAGE>
 
and interest ("Taxes") due or claimed to be due have been paid, other than those
Taxes being contested in good faith and those Taxes for which adequate reserves
or accruals have been established in accordance with generally accepted
accounting principles, except where the failure to file such returns or to pay
such Taxes is not reasonably likely to have, singly or in the aggregate, a
Material Adverse Effect on the Company and its Subsidiaries, taken as a whole.
The Company knows of no actual or proposed additional tax assessments for any
fiscal period against the Company or any of its Subsidiaries that, individually
or in the aggregate, would have a Material Adverse Effect on the Company and its
Subsidiaries, taken as a whole.

            (q) Each of the Company and its Subsidiaries is in substantial
compliance with all laws, rules and regulations applicable to the Company, and
each such Subsidiary, and the Company and its Subsidiaries own or possess and
are operating in compliance in all material respects with the terms, provisions,
conditions, restrictions and limitations contained in all licenses, franchises,
approvals, certificates and permits from all Federal, State, territorial,
foreign and local governmental and regulatory authorities which are necessary to
own or lease and operate their respective properties and assets and to conduct
their respective businesses, except where the failure to comply with any of the
foregoing would not have a Material Adverse Effect on the Company and its
Subsidiaries, taken as a whole.

            (r) Assuming the accuracy of the Purchaser's representations and
warranties set forth in Section 3.2 hereof and the due performance by the
Purchaser of the covenants and agreements set forth in Section 3.2 hereof, the
sale of the Securities to the Purchaser in the manner contemplated by this
Agreement does not require registration of the Securities under the Act.

     Section 3.2.  Representations and Warranties of the Purchaser and
Purchaser's Parent.

            (a) Each of the Purchaser and Purchaser's Parent represents and
warrants to, and covenants and agrees with, the Company that: (1) the Securities
to be acquired by the Purchaser hereunder are being acquired for its own account
or an account with respect to which it exercises sole investment discretion and
it or any such account is a "qualified institutional buyer" as defined in Rule
144A promulgated under the Act ("QIB") or an "Accredited Investor" as defined
under Regulation D promulgated under the Act and has no intention of
distributing or reselling such Securities or any part thereof in any transaction
which would be in violation of the securities laws of the United States of
America or any state; (2) each of the Purchaser and Purchaser's Parent
acknowledges that the Securities have not been or will not be registered under
the Act and that the Securities may not be offered or sold within the United
States or to, or for the account or benefit of, United States persons, except as
set forth below; (3) Purchaser shall not resell or otherwise transfer any of
such Securities within two (2) years after the original issuance of the
Securities, except (A) to the Company or any of its Subsidiaries, (B) inside the
United

                                      -11-
<PAGE>
 
States to a QIB in compliance with Rule 144A promulgated under the Act, (C)
inside the United States to an "Accredited Investor" that, prior to such
transfer, furnishes (or has furnished on its behalf by a United States broker-
dealer) to the Company a signed letter containing certain representations and
agreements relating to the restrictions on transfer of the Securities, (D)
outside the United States in compliance with Rule 904 promulgated under the Act,
(E) pursuant to any other exemption from registration provided under the Act (if
available) including Rule 144 promulgated thereunder or (F) pursuant to an
effective registration statement under the Act, and (4) Purchaser will give to
each person to whom it transfers the Securities notice of any restrictions on
transfer of such Securities; and subject, nevertheless, to the disposition of
the Purchaser's property being at all times within its control.  If the
Purchaser should in the future decide to dispose of any of the Securities, the
Purchaser understands and agrees that it may do so only in compliance with the
Act, as then in effect, and that stop-transfer instructions to that effect will
be in effect with respect to the Securities.  If the Purchaser should decide to
transfer or otherwise dispose of the Securities, the Purchaser shall comply with
the requirements set forth in the relevant Basic Documents.  The Purchaser
agrees to the imprinting, so long as required by the terms of the relevant Basic
Document, of the applicable legends contained in the Common Stock Warrant on
each certificate representing the Common Stock Warrant or Warrant Shares.

            (b) Each of the Purchaser and Purchaser's Parent also represents 
that no part of the funds to be used to purchase the Securities to be purchased
by the Purchaser constitutes assets of any employee benefit plan, except as
otherwise disclosed in writing to the Company on or prior to the Closing Date.
As used in this Section 3.2(b), the term "employee benefit plan" shall have the
meaning assigned to such term in Section 3 of ERISA.

            (c) Each of the Purchaser and Purchaser's Parent also represents and
warrants to the Company that (i) the Purchaser is a wholly-owned subsidiary of
Purchaser's Parent, (ii) each of the Purchaser and Purchaser's Parent has
received and reviewed the Information; (iii) each of Purchaser and Purchaser's
Parent has authorized the purchase of the Securities; and (iv) the purchase of
Securities does not violate the Purchaser's charter, by-laws, or other
organizational documents or any law or regulation to which it is subject.

counsel may rely upon the opinion of counsel (reasonably satisfactory to the
Purchaser) admitted to practice in such jurisdiction.  Any opinion relied upon

only in the ordinary course.

            (e) At the Time of Purchase and after giving effect to the
consummation of the transactions contemplated by this Agreement and the other
Basic Documents, there shall exist no Default or Event of Default.

            (f) As to the Purchaser, the purchase of and payment for the

limitation, Regulation G, T, U or X of the Board of Governors of such Federal

than debt securities with no equity feature), the Purchaser shall have the
preferential right to subscribe for and purchase such securities in a proportion
equal to the greater of (i) the number of shares of Common Stock, together with
the Warrant Shares issuable upon exercise of the Warrant, owned by Purchaser to
the total number of outstanding shares of Common Stock and (ii) 20% of the

Company's offer as to the full number of securities offered to it or any lesser
number, by written notice thereof given by it to the Company prior to the
expiration of 15 days, in which event the Company shall promptly sell and the
Purchaser shall buy, upon the terms specified, the number of securities agreed
to be purchased by the Purchaser; provided, notwithstanding the other provisions
of this Section, in connection with a Rule 144A offering, the Company may sell
the entire amount offered to one or more initial purchasers (the "Initial
Purchaser") so long as the company causes the Initial Purchaser to offer the
same number of securities to the Purchaser that the Company would otherwise be
required to offer the Purchaser and on the same terms and in the same manner as
the Initial Purchaser offers such securities to other investors.  The Company
shall be free at any time prior to 90 days after the date of its notice of offer
to the Purchaser, to offer and sell to any third party or parties the number of
such securities not agreed by the Purchaser to be purchased by the Purchaser, at
a price and on payment terms no less favorable to the Company than those
specified in such notice of offer to the Purchaser.  However, if such third
party sale or sales are not consummated within such 90-day period, the Company
shall not sell such securities as shall not have been purchased within such
period without again complying with this Section 5.7.

     Section 5.8.  Execution of Basic Documents.  At the Closing, the parties
shall execute and deliver to one another the Basic Documents.

period unless (the "Junior Distribution Condition") the Corporation has declared
and paid in cash dividends on the Series B Preferred Stock for eight (8)
consecutive quarters.  When dividends are not paid in full upon the Preferred
Stock, all dividends declared upon shares of the Preferred Stock shall be
declared pro rata.  Unless the Junior Distribution Conditions have been
satisfied, no dividends (other than dividends payable in Common Stock) shall be
declared or paid or set apart for payment or other distribution upon any Junior
Stock, nor shall any Junior Stock be redeemed, purchased or otherwise acquired
by the Corporation for any consideration (or any payment made to or available
for a sinking fund for the redemption of any shares of such stock) by the
Corporation.

     4.   Ranking.  The Series B Preferred Stock shall, with respect to dividend
rights and rights on liquidation, winding-up and dissolution, rank senior to all
classes of Common Stock of the Corporation and senior to all other classes or
series of any class of Preferred Stock of the Corporation, whether currently
outstanding or issued hereafter (collectively, the "Junior Stock").

     5.   Conversion.  The Preferred Stock shall be convertible as follows:

          (A) Optional Conversion.  The Series B Preferred Stock shall be
convertible, without the payment of any additional consideration by the Holders,
at the option of the Holders upon 90 days' prior written notice to the
Corporation, on or after April 30, 2000 at the office of the Corporation or any
transfer agent for the Series B Preferred Stock, into the number of fully paid
and non-assessable shares of Common Stock determined by dividing the Liquidation
Preference by the greater of [the lesser of (i) the average closing price for
the Common Stock on the three trading days up to and including the date of
signing and (ii) the average closing price for the Common Stock on the three
trading days prior to the Closing Date] and the Fair Market Value of the
Corporation's Common Stock in effect at the time of conversion.

              Notwithstanding the foregoing, no Holder or "group" (as defined 
under the Exchange Act) of Holders shall be able to convert any shares of Series
B Preferred Stock pursuant to this Section 5(A) to the extent that the
conversion of such shares would cause such Holder or "group" of Holders to own
or be deemed to own by The Nasdaq Stock Market more than 19.9% of the
outstanding Common Stock of the Corporation prior to such conversion.

          (B) Merger, Consolidation or Disposition of Assets.  Notwithstanding
anything to the contrary contained in Section 5(A) in case a third party makes a
tender offer for in excess of 50% of the outstanding Common Stock, or the
Corporation shall merge or 


                                     - 4 -
<PAGE>
 
consolidate into another corporation, or shall sell, transfer or otherwise
dispose of all or substantially all of its property, assets or business to
another corporation and pursuant to the terms of such tender merger,
consolidation or disposition, cash or shares of common stock of the successor or
acquiring corporation are to be received by or distributed to the holders of all
or part of the Common Stock of the Corporation, then each Holder of a share of
the Series B Preferred Stock shall have the right thereafter to receive, upon
conversion of such share of Series B Preferred Stock at Fair Market Value
conditional upon the consummation of such transaction, such cash or shares of
Common Stock constituting the cash or number of shares of common stock of the
successor or acquiring corporation, as the case may be, receivable upon or as a
result of such merger, consolidation or disposition of assets by a holder of the
number shares of Common Stock into which one (1) share of the Series B Preferred
Stock could be converted immediately prior to such event.

          (C) Mechanisms of Conversion.  Before any Holder of the Series B
Preferred Stock shall be entitled to convert the same into Common Stock, the
Holder shall give 90 days' prior written notice to the Corporation and shall
surrender to the Corporation at the office of the Corporation or of any transfer
agent for the Series B Preferred Stock, the certificate or certificates
representing such Series B Preferred Stock, accompanied by written notice to the
Corporation that the Holder elects to convert all or a specified number of such
shares and stating therein his name or the name or names of his nominees in
which he wishes the certificate or certificates for Common Stock to be issued.
The Corporation shall, as soon as practicable thereafter, issue and deliver at
such office to such Holder of the Series B Preferred Stock or to his nominee or
nominees a certificate representing the number of shares of Common Stock to
which such Holder shall be entitled as aforesaid and, if less than the full
number of shares of the Series B Preferred Stock evidenced by such surrendered
certificate or certificates are being converted, a new certificate or
certificates, of like tenor, for the number of shares of the Series B Preferred
Stock evidenced by such surrendered certificates less the number of such shares
being converted.  Dividends shall continue to accrue on shares of Series B
Preferred Stock from the date of the notice of conversion through the date of
conversion.

          (D) Fractional Shares.  No fractional shares or scrip representing
fractional shares shall be issued upon conversion of any Series B Preferred
Stock.  If the conversion of any shares of Series B Preferred Stock results in a
fraction of a share of Common Stock, an amount equal to such fraction multiplied
by the Fair Market Value per share of Common Stock on the day of delivery to the
Corporation of notice of conversion of such shares or dividends, as applicable,
shall be promptly paid by the Corporation to the Holder of such shares in
immediately available funds.

     6.   Voting Rights.  Except as required by the Oklahoma General Corporation
Act, or as set forth herein, the Holders shall not be entitled to vote on any
matter submitted to a vote of stockholders of the Corporation.  On any matters
on which the Holders shall be so entitled to vote, they shall be entitled to one
vote for each share held.  Except for the issuance of 50,000 


                                     - 5 -
<PAGE>
 
shares of the Series B Preferred Stock to Chesapeake Gothic Corp., an Oklahoma
corporation, pursuant to that certain Securities Purchase Agreement dated March
31, 1998, any remaining shares of Series B Preferred Stock can only be issued as
PIK Stock and may not be issued for any other purpose or in any other manner
without the prior approval of Holders of 75% of the Series B Preferred Stock.

     7.   Redemption.

          (A) Optional Redemption.  (i)  At any time prior to April 30, 2000,
the Series B Preferred Stock may be redeemed (subject to contractual and other
restrictions with respect thereto and the legal availability of funds therefor)
at the option of the Corporation in whole or, from time to time, in part, in the
manner provided in Section 7(C) hereof at 105% of the Liquidation Preference of
the Series B Preferred Stock so redeemed, payable in cash out of the net
proceeds from a public or private offering of any equity security (as defined in
the Exchange Act), plus accrued and unpaid dividends (whether or not declared),
which shall also be paid in cash (whether or not otherwise payable in cash) to
the Redemption Date.

              (ii) At any time on or after April 30, 2000, the Series B 
Preferred Stock may be redeemed (subject to contractual and other restrictions
with respect thereto and the legal availability of funds therefor) at the option
of the Corporation in whole or, from time to time, in part, in the manner
provided in Section 7(C) hereof at any time at a redemption price equal to the
Liquidation Preference of the Series B Preferred Stock so redeemed, payable in
cash, plus accrued and unpaid dividends (whether or not declared), which shall
also be paid in cash (whether or not otherwise payable in cash) to the
Redemption Date.

          (B) Mandatory Redemption.  The Corporation shall redeem all
outstanding shares of Series B Preferred Stock on June 30, 2008 at a redemption
price equal to the Liquidation Preference thereof, payable in cash or, at the
option of the Corporation, in shares of Common Stock of the Corporation at Fair
Market Value, plus accrued and unpaid dividends (whether or not declared).

          (C) Procedure for Redemption.

              (i)  In the event of a redemption of less than all of the Series B
Preferred Stock, the shares so redeemed will be determined by the Corporation
pro rata according to the number of shares held by each Holder.

              (ii) The Corporation shall send a written notice of redemption 
(the "Redemption Notice") by first-class mail, postage prepaid, not fewer than 3
days nor more than 30 days prior to the applicable Redemption Date to each
Holder as of the record date fixed for such redemption of Series B Preferred
Stock at such Holder's address as the same appears on the stock books of the
Corporation; provided, however, that no failure to give such notice to any


                                     - 6 -
<PAGE>
 
Holder or Holders nor any deficiency therein shall affect the validity of the
procedure for the redemption of any shares of Series B Preferred Stock to be
redeemed except as to the Holder or Holders to whom the Corporation has failed
to give said notice or except as to the Holder or Holders whose notice was
defective. The Redemption Notice shall state:

                   (A) whether all or less than all the outstanding shares of
Series B Preferred Stock are to be redeemed and the total number of shares of
Series B Preferred Stock being redeemed;

                   (B) the number of shares of Series B Preferred Stock held of
record by that specific Holder that the Corporation intends to redeem;

                   (C) the applicable Redemption Date;

                   (D) the manner and place or places at which payment for the
shares called for redemption will, upon presentation and surrender to the
Corporation of the Series B Preferred Stock Certificates evidencing the shares
being redeemed, be made; and

                   (E) that dividends on the shares of Series B Preferred Stock
being redeemed shall cease to accrue on the applicable Redemption Date.

             (iii) On the applicable Redemption Date, the full applicable
redemption price shall become payable for the shares of Series B Preferred Stock
being redeemed on the applicable Redemption Date.  As a condition of payment of
the applicable redemption price, each Holder of Series B Preferred Stock must
surrender a Series B Preferred Stock Certificate or Certificates representing
the shares of Series B Preferred Stock being redeemed by the Corporation in the
manner and at the place designated in the applicable Redemption Notice.  The
full applicable redemption price for such shares properly tendered for payment
shall be paid to the person whose name appears on such certificate or
certificates as the owner thereof, on and after the applicable Redemption Date
when and as certificates for the shares being redeemed are properly tendered for
payment.  Each surrendered Series B Preferred Stock Certificate shall be
canceled and retired.  In the event that less than all of the shares represented
by any such certificate are redeemed, a new certificate shall be issued
representing the unredeemed shares.

             (iv)  On the applicable Redemption Date, unless the Corporation
defaults in the payment of the applicable redemption price, dividends will cease
to accrue with respect to the shares of Series B Preferred Stock called for
redemption, regardless of whether the Holder has surrendered the Series B
Preferred Stock certificate representing same.  All rights of Holders of such
redeemed shares will terminate except for the right to receive the applicable
redemption price.

     8.   Information.

          So long as any of the Series B Preferred Stock remains outstanding,
the Corporation shall provide to each Holder, within ten (10) days of filing,
such periodic and other reports as the Corporation is required to file under the
Exchange Act.  Such reports shall be mailed to the Holder at its address as it
appears on the stock records of the Corporation or such other address as the
Holder may have provided.

     9.   Payment on Liquidation.

          (A) Upon any voluntary or involuntary liquidation, dissolution or
winding-up of the Corporation, Holders of Series B Preferred Stock will be
entitled to receive an amount in cash equal to the Liquidation Preference,
before any distribution is made on any Common Stock or other Preferred Stock of
the Corporation.  After payment of the full amount of the Liquidation Preference
to which they are entitled, Holders of Series B Preferred Stock will not be
entitled to any further participation in any distribution of assets of the
Corporation.

          (B) For the purposes of this Section 9, neither the voluntary sale,
conveyance, exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all the property or assets of the
Corporation nor the consolidation or merger of the Corporation with one or more
corporations shall be deemed a voluntary or involuntary liquidation, dissolution
or winding-up of the Corporation, unless such sale, conveyance, exchange or
transfer shall be in connection with a dissolution or winding-up of the business
of the Corporation.

     10.  Exclusion of Other Rights.  Except as may otherwise be required by the
Oklahoma General Corporation Act, shares of the Series B Preferred Stock shall
not have any preferences or relative, participating, optional or other special
rights, other than those specifically set forth in this Certificate of
Designation (as such Certificate may be amended from time to time) and in the
Corporation's Certificate of Incorporation, as amended.  Except as otherwise
provided in writing, no shares of Series B Preferred Stock shall have any
preemptive or subscription rights whatsoever as to any securities of the
Corporation.

     11.  Reissuance of Preferred Stock.  Shares of Series B Preferred Stock
that have been issued and reacquired by the Corporation in any manner, including
shares purchased or redeemed, shall (upon compliance with any applicable
provisions of the Oklahoma General Corporation Act) have the status of
authorized and unissued shares of Preferred Stock undesignated as to series and
may be redesignated and reissued as part of any series of Preferred Stock,
except the Series B Preferred Stock.

     12.  Business Day.  If any payment or redemption shall be required by the
terms hereof to be made on a day that is not a Business Day, such payment,
redemption or exchange shall be made on the immediately succeeding Business Day.

     13.  Headings of Subdivisions.  The headings of the various subdivisions
hereof are for convenience of reference only and shall not affect the
interpretation of any of the provisions hereof.

     14.  Severability of Provisions.  If any right, preference or limitation of
the Series B Preferred Stock set forth in this Certificate of Designation (as
such Certificate may be amended from time to time) is invalid, unlawful or
incapable of being enforced by reason of any rule or law or public policy, all
other rights, preferences and limitations set forth in this Certificate of
Designation (as so amended) which can be given effect without the invalid,
unlawful or unenforceable right, preference or limitation shall, nevertheless,
remain in full force and effect, and no right, preference or limitation herein
set forth shall be deemed dependent upon any other such right, preference or
limitation unless so expressed herein.

     15.  Notice.  All notices and other communications provided for or
permitted to be given to the Corporation hereunder shall be made by hand
delivery, next-day air courier or certified, first-class mail to the Corporation
at its principal executive offices (currently located at 5727 South Lewis
Avenue, Suite 700, Tulsa Oklahoma 74105).

     16.  Amendments.  Any provisions of this Certificate of Designation may be
amended by the Corporation, or waived by the Holders, in each case with the
written consent of Holders representing a majority of the outstanding shares of
Series B Preferred Stock.

     1.1  Exercise Period.

          The Warrant represented hereby may be exercised by the Holder hereof,

     1.2  Method of Exercise.

          To exercise the Warrants, the Holder hereof shall deliver to the
Company, at the Warrant Office designated in Section 2.1 hereof, (i) a written
notice in the form of the Subscription Notice attached as Exhibit I hereto,
stating therein the election of such holder to exercise the Warrant in the
manner provided in the Subscription Notice; (ii) payment in full of the Exercise
Price in cash or by bank check or wire transfer for all Warrant Shares purchased
hereunder, or a written notice (a "Cashless Exercise" notice) to the Company
that such Holder is exercising the Warrant (or a portion thereof) by authorizing
the Company to withhold from issuance a number of Warrant Shares issuable upon
such exercise of the Warrant which, when multiplied by the Exercise Price, is
equal to the Exercise Price for the total number of Warrant Shares to which such
exercise relates (and such withheld shares shall no longer be issuable under
this Warrant); (iii) if this Warrant is not registered in the name of the
Holder, an Assignment or Assignments in the form set forth in Exhibit II hereto
evidencing the assignment of this Warrant to the current Holder; and (iv) this
Warrant. The Warrants shall be deemed to be exercised on the date of receipt by
the Company of the Subscription Notice, accompanied by payment for the Warrant
Shares and surrender of this Warrant, as aforesaid, and such date is referred to
herein as the "Exercise Date".  Upon such exercise, the Company shall, as
promptly as practicable and in any event within five (5) business days, issue
and deliver to such holder a certificate or certificates for the full number of
the Warrant Shares purchased by such holder hereunder, and shall, unless the
Warrant has expired, deliver to the holder hereof (within such five (5) day
period) a new Warrant representing the right to purchase the number of Warrant
Shares, if any, with respect to which the Warrant shall not have been previously
exercised, but in all other respects identical to this Warrant. As permitted by
applicable law, the Person in whose name the certificates for Common Stock are
to be issued shall be deemed to have become a holder of record of such Common
Stock on the Exercise Date and shall be entitled to all of the benefits of such
holder on the Exercise Date, including without limitation, the right to receive
dividends and other distributions for which the record date falls on or after
the Exercise Date and the right to exercise voting rights.

     1.3  Expenses and Taxes.  The Company shall pay all expenses and taxes
(including, without limitation, all documentary, stamp, transfer or other
transactional taxes), other than income taxes payable by the Holder,
attributable to the preparation, issuance or delivery of the Warrant and of the
issuance of the Warrant Shares.

     1.4  Reservation of Shares.  The Company shall reserve at all times so long
as the Warrant remains outstanding, free from preemptive rights, out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the exercise of the Warrant, a sufficient number of shares of Common
Stock to provide for the exercise of the Warrant. The Company shall take all
such actions as may be necessary to assure that all such Warrant Shares

                                      -3-
<PAGE>
 
may be so issued without violation of any applicable law or governmental
regulation or any requirements of any domestic securities exchange or automated
quotation system upon which shares of Common Stock may be listed or quoted
(except for official notice of issuance, which shall be immediately delivered by
the Company upon each such issuance). The Company shall take all such actions as
may be necessary to assure that all such Warrant Shares shall be authorized,
approved for and listed on any national securities exchange or quotation system
on which the Company's Common Stock is listed or quoted. The Company shall not
take any action which would cause the number of authorized but unissued shares
of Common Stock to be less than the number of such shares required to be
reserved hereunder for issuance upon exercise of the Warrant.  The Company will
from time to time take all action as may be necessary to assure that the par
value of the Common Stock is at all times equal to or less than the Exercise
Price.

     1.5  Valid Issuance.  All Warrant Shares that may be issued upon any
exercise of the Warrant will, upon issuance by the Company, be duly and validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
with respect to the issuance thereof and, without limiting the generality of the
foregoing, the Company shall take no action or fail to take any action which
will cause a contrary result (including, without limitation, any action that
would cause the Exercise Price then in effect to be less than the par value, if
any, of the Common Stock).

     1.6  Purchase Agreement.  The Warrant represented hereby is part of a duly
authorized issuance and sale of warrants to purchase Common Stock pursuant to
that certain Securities Purchase Agreement dated March 31, 1998 (the
"Agreement"), between the Company and the Holder.

     1.7  Acknowledgment of Rights.  At the time of the exercise of the Warrants
in accordance with the terms hereof and upon the written request of the Holder
hereof, the Company will acknowledge in writing its continuing obligation to
afford to such Holder any rights (including, without limitation, any right to
registration of the Warrant Shares) to which such Holder shall continue to be
entitled after such exercise in accordance with the provisions of this Warrant;
provided, however, that if the holder hereof shall fail to make any such
request, such failure shall not affect the continuing obligation of the Company
to afford to such Holder any such rights.

     1.8  No Fractional Shares.  The Company shall not be required to issue
fractional shares of Common Stock (or other securities) on the exercise of this
Warrant. If more than one Warrant shall be presented for exercise at the same
time by the same Holder, the number of full Warrant Shares which shall be
issuable upon such exercise shall be computed on the basis of the aggregate
number of whole Warrant Shares purchasable on exercise of the Warrants so
presented.

                                      -4-
<PAGE>
 
     1.9  Assistance and Cooperation.  The Company shall not close its books
against the transfer of this Warrant or of any Warrant Share in any manner which
interferes with the timely exercise of this Warrant.  The Company shall assist
and cooperate with any Holder required to make any governmental filings or
obtain any governmental approvals prior to or in connection with any exercise of
this Warrant (including, without limitation, making any filings required to be
made by the Company).

     1.10 Delayed Exercise.  Notwithstanding any other provision hereof, if an
exercise of any portion of this Warrant is to be made in connection with a
registered public offering or the sale of the Company, the exercise of any
portion of this Warrant may, at the election of the Holder hereof, be
conditioned upon the consummation of the public offering or sale of the Company
in which case such exercise shall not be deemed to be effective until the
consummation of such transaction.

                                  ARTICLE II

                                   TRANSFER

     2.1  Warrant Office.  The Company shall maintain an office for certain
purposes specified herein (the "Warrant Office"), which office shall initially
be the Company's offices at 5727 South Lewis Avenue, Suite 8700, Tulsa, Oklahoma
74105, and may subsequently be such other office of the Company or of any
transfer agent of the Common Stock in the continental United States as to which
written notice has previously been given to the holder hereof. The Company shall
maintain, at the Warrant Office, a register for the Warrants in which the
Company shall record the name and address of the Person in whose name this
Warrant has been issued, as well as the name and address of each permitted
assignee of the rights of the registered owner hereof.

     2.2  Ownership of Warrants.  The Company may deem and treat the Person in
whose name the Warrant is registered as the Holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Article II. Notwithstanding the foregoing, the Warrants
represented hereby, if otherwise properly assigned in compliance with this
Article II (i.e., but for registration of the transfer at the Warrant Office),
may be exercised by an assignee for the purchase of Warrant Shares without
having a new Warrant issued.

     2.3  Restrictions on Transferability of Warrant.  Subject to the transfer
conditions referred to herein, this Warrant and all rights hereunder (including,
but not limited to, Registration Rights under Article VI) are transferable, in
whole or in part, without charge to the Holder, upon surrender of this Warrant
with a properly executed Assignment (in the form of Exhibit II hereto) at the
Warrant Office of the Company. The Company agrees to maintain at the Warrant
Office books for the registration and transfer of the Warrants. The Company
shall, from time to time, register the transfer of the Warrants in such books
upon surrender of any such Warrant at the Warrant Office accompanied by a
properly executed Assignment and written instructions for transfer satisfactory
to the Company. Upon any such transfer and upon payment by the holder or its
transferee of any applicable transfer taxes, a new Warrant shall be issued to
the transferee and the surrendered Warrant shall be canceled by the Company. The
Company shall pay all taxes (other than securities transfer taxes or income
taxes) and all other expenses and charges payable in connection with the
transfer of the Warrants pursuant to this Section 2.3. Prior to any transfer as
provided herein, the transferor shall provide written notice to the Company.

     2.4  Warrant Exchangeable for Different Denominations.  This Warrant is
exchangeable, upon the surrender hereof, by the Holder at the Warrant Office of
the Company, for new Warrants of like tenor representing in the aggregate the
purchase rights hereunder, and each of such new Warrants shall represent such
portion of such rights as is designated by the Holder at the time of such
surrender. The date the Company initially issues this Warrant shall be deemed to
be the "Date of Issuance" hereof regardless of the number of times new
certificates representing the unexpired and unexercised rights formerly
represented by this Warrant shall be issued. All Warrants representing portions
of the rights hereunder are referred to herein as the "Warrants."

     2.5  Compliance with Securities Laws.  Notwithstanding any other provisions
contained in this Warrant, the Holder hereof understands and agrees that the
following restrictions and limitations shall be applicable to all Warrant Shares
and to all resales or other transfers thereof pursuant to the Securities Act:

          2.5.1  The holder hereof agrees that the Warrant and Warrant Shares
shall not be sold or otherwise transferred unless the Warrant or Warrant Shares
are registered under the Securities Act and applicable state securities or blue
sky laws or are sold in a transaction that is exempt therefrom.

          2.5.2  A legend in substantially the following form will be placed on
the certificate(s) evidencing the Warrant Shares:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE 
          HAVE NOT BEEN REGISTERED UNDER THE SECURITIES 
          ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR 
          ANY STATE OR OTHER APPLICABLE SECURITIES LAWS
          AND, ACCORDINGLY, THE SECURITIES REPRESENTED 
          BY THIS CERTIFICATE MAY NOT BE RESOLD, PLEDGED, 
          OR OTHERWISE TRANSFERRED, EXCEPT PURSUANT TO
          AN EFFECTIVE REGISTRATION STATEMENT UNDER, OR 
          IN A TRANSACTION EXEMPT FROM REGISTRATION 
          UNDER, THE SECURITIES ACT AND IN ACCORDANCE 
          WITH ANY STATE OR OTHER APPLICABLE SECURITIES 
          LAWS."

          2.5.3  Stop transfer instructions will be imposed with respect to the
Warrant Shares so as to restrict resale or other transfer thereof not in
accordance with this Section 2.5.


                                  ARTICLE III

                                 ANTI-DILUTION

     3.   Adjustment Effectuating Anti-Dilution.  The number of shares of Common
Stock (i.e., Warrant Shares) obtainable upon exercise of this Warrant shall be
subject to adjustment from time to time as provided in this Article III.

     3.1. Adjustment of Warrant Number of Shares.  The number of Warrant
Shares purchasable upon the exercise of the Warrant shall be subject to
adjustment as follows:

          (a) In the case the Company shall issue rights, options or warrants
entitling recipients thereof to subscribe for or purchase shares of Common Stock
at a price per share which is lower than the Fair Market Value per share of
Common Stock (as defined in paragraph (c) of this Section 3.1) as of the date of
issuance, the number of Warrant Shares thereafter purchasable upon the exercise
of each Warrant shall be determined by multiplying the number of Warrant Shares
theretofore purchasable upon exercise of each Warrant by a fraction, of which
the numerator shall be the number of shares of Common Stock outstanding on the
date of issuance of such rights, options or warrants plus the number of
additional shares of Common Stock offered for subscription or purchase or
pursuant to such rights, options or warrants, and of which the

                                      -7-
<PAGE>
 
denominator shall be the number of shares of Common Stock outstanding on the
date of issuance of such rights, options or warrants plus the number of shares
which the aggregate offering price of the total number of shares of Common Stock
so offered would purchase at such Fair Market Value.  Such adjustment shall be
made whenever such rights, options or warrants are issued, and shall become
effective retroactively immediately after the date of such issuance.

          (b) In the case the Company shall issue evidences of its indebtedness
or assets (excluding cash dividends or distributions out of earnings) or rights,
options or warrants or convertible securities containing the right to subscribe
for or purchase shares of Common Stock (excluding those referred to in paragraph
(a) of this Section 3.1) then in each case the number of Warrant Shares
thereafter purchasable upon the exercise of each Warrant shall be determined by
multiplying the number of Warrant Shares theretofore purchasable upon exercise
of the Warrant, by a fraction, of which the numerator shall be the then Fair
Market Value per share of Common Stock (as defined in paragraph (c) of this
Section 3.1) on the date of such distribution, and of which the denominator
shall be such Fair Market Value per share of Common Stock, less the then fair
value (as determined by the Board of Directors of the Company, whose
determination shall be conclusive) of the portion of the assets or evidences of
indebtedness so distributed or of such subscription rights, options or warrants,
or of such convertible securities applicable to one share of Common Stock.  Such
adjustment shall be made whenever any such distribution is made, and shall
become effective on the date of distribution retroactive to the date of the
distribution.

          (c) For the purposes of this Section 3.1, "Fair Market Value" shall
mean with respect to the Company's Common Stock the average of the closing
prices of such security's sales on all domestic securities exchanges on which
such security may at the time be listed, or, if there have been no sales on any
such exchange on any day, the average of the highest bid and lowest asked prices
on all such exchanges at the end of such day, or, if on any day such security is
not so listed, the average of the representative bid and asked prices quoted in
the NASDAQ System as of 4:00 P.M., New York time, on such day, or, if on any day
such security is not quoted in the NASDAQ System, the average of the highest bid
and lowest asked prices on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of ten days
consisting of the day as of which "Fair Market Value" is being determined and
the nine consecutive business days prior to such day; provided, that if such
security is listed on any domestic securities exchange, the term "business days"
as used in this sentence means business days on which such exchange is open for
trading.  If at any time such security is not listed on any domestic securities
exchange or quoted in the NASDAQ System or the domestic over-the-counter market,
the "Fair Market Value" shall be the fair value thereof determined jointly by
the Company and the Holder; provided, that if such parties are unable to reach
agreement within a reasonable period of time, such fair value shall be
determined by an appraiser jointly selected by

                                      -8-
<PAGE>
 
the Company and the Holder.  The determination of such appraiser shall be final
and binding on the Company and the Holder, and the fees and expenses of such
appraiser shall be paid jointly by the Company and the Holder.

          (d) No adjustment in the number of Warrant Shares purchasable
hereunder shall be required unless such adjustment would require an increase or
decrease of at least 1% in the number of Warrant Shares purchasable upon the
exercise of each Warrant; provided, however, that any adjustments which by
reason of this paragraph (d) are not required to be made shall be carried
forward and taken into account in any subsequent adjustment.

     3.2  Stock Splits and Reverse Splits.  In the event that the Company shall
at any time subdivide its outstanding shares of Common Stock into a greater
number of shares (by stock split, stock dividend, recapitalization or
otherwise), the number of Warrant Shares purchasable pursuant to this Warrant
immediately prior to such subdivision shall be proportionately increased.
Conversely, in the event that the outstanding shares of Common Stock shall at
any time be combined into a smaller number of shares (by reverse stock split or
otherwise), the number of Warrant Shares purchasable upon the exercise of this
Warrant immediately prior to such combination shall be proportionately reduced.

     3.3  Reorganizations and Asset Sales.  If any capital recapitalization,
reorganization or reclassification of the capital stock of the Company, or any
consolidation, merger or share exchange of the Company with another Person, or
the sale, transfer or other disposition of all or substantially all of its
assets to another Person shall be effected in such a way that a holder of Common
Stock of the Company shall be entitled to receive capital stock, securities or
assets with respect to or in exchange for their shares, then the following
provisions shall apply:

          3.3.1  As a condition of such recapitalization, reorganization,
reclassification, consolidation, merger, share exchange, sale, transfer or other
disposition (except as otherwise provided below in this Section 3.3), lawful and
adequate provisions (in form and substance satisfactory to the Holders of
Warrants representing a majority of the Warrant Shares obtainable upon exercise
of all of the Warrants then outstanding) shall be made whereby the holder of
Warrants shall thereafter have the right to purchase and receive upon the terms
and conditions specified in this Warrant and in lieu of or addition to (as the
case may be) the Warrant Shares immediately theretofore receivable upon the
exercise of the rights represented hereby, such shares of capital stock,
securities or assets as may be issued or payable with respect to or in exchange
for a number of outstanding shares of such Common Stock equal to the number of
Warrant Shares immediately theretofore so receivable had such recapitalization,
reorganization, reclassification, consolidation, merger, share exchange or sale
not taken place, and in any such case appropriate provision (in form and
substance satisfactory to the Holders of Warrants representing a majority of the
Warrant Shares obtainable upon exercise of all of the Warrants

                                      -9-
<PAGE>
 
then outstanding) shall be made with respect to the rights and interests of such
Holder(s) to the end that the provisions hereof shall thereafter be applicable,
as nearly as possible, in relation to any shares of capital stock, securities or
assets thereafter deliverable upon the exercise of Warrants.

          3.3.2  The Company shall not effect any such consolidation, merger,
share exchange, sale, transfer or other disposition unless prior to or
simultaneously with the consummation thereof the successor Person (if other than
the Company) resulting from such consolidation, share exchange or merger or the
Person purchasing or otherwise acquiring such assets shall have assumed by
written instrument executed and mailed or delivered to each of the Holders
hereof at the last address of such holder appearing on the books of the Company,
(i) the obligation to deliver to such holder such shares of capital stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to receive, and (ii) all other liabilities and
obligations of the Company hereunder. As a condition to any consolidation, share
exchange or merger, such successor Person must assume the Company's obligations
hereunder by written instrument and issue a new warrant revised to reflect the
modifications in this Warrant effected pursuant to this Section 3.3.

     3.4  Notice of Adjustment.  Whenever the number of Warrant Shares issuable
upon the exercise of the Warrants shall be adjusted as herein provided, or the
rights of the Holder hereof shall change by reason of other events specified
herein, the Company shall compute the adjusted number of Warrant Shares in
accordance with the provisions hereof and shall prepare an Officer's Certificate
setting forth the adjusted number of Warrant Shares issuable upon the exercise
of the Warrants or specifying the other shares of stock, securities or assets
receivable as a result of such change in rights, and showing in reasonable
detail the facts and calculations upon which such adjustments or other changes
are based. The Company shall promptly cause to be mailed to the holder hereof
copies of such Officer's Certificate together with a notice stating that the
number of Warrant Shares purchasable upon exercise of the Warrants have been
adjusted and setting forth the adjusted number of Warrant Shares purchasable
upon the exercise of the Warrants.

     3.5  Notices to Holders.  In case at any time the Company proposes:

          (i)  to declare any dividend upon its Common Stock payable in capital
stock or make any dividend or other distribution to the holders of its Common
Stock;

          (ii) to offer for subscription pro rata to all of the holders of its
Common Stock any additional shares of capital stock of any class or other
rights;

                                     -10-
<PAGE>
 
          (iii) to effect any capital reorganization, or reclassification of
the capital stock of the Company, or consolidation, merger or share exchange of
the Company with another Person, or sale, transfer or other disposition of all
or substantially all of its assets; or

          (iv)  to effect a voluntary or involuntary dissolution, liquidation or
winding up of the Company,

then, in any one or more of such cases, the Company shall give the Holder hereof
(a) at least 20 days' (but not more than 90 days') prior written notice of the
date on which the books of the Company shall close or a record shall be taken
for such dividend, distribution or subscription rights or for determining rights
to vote in respect of such issuance, recapitalization, reorganization,
reclassification, consolidation, merger, share exchange, sale, transfer,
disposition, dissolution, liquidation or winding up, and (b) in the case of any
such issuance, recapitalization, reorganization, reclassification,
consolidation, merger, share exchange, sale, transfer, disposition, dissolution,
liquidation or winding up, at least 20 days' (but not more than 90 days') prior
written notice of the date when the same shall take place. Such notice in
accordance with the foregoing clause (a) shall also specify, in the case of any
such dividend, distribution or subscription rights, the date on which the
holders of Common Stock shall be entitled thereto, and such notice in accordance
with the foregoing clause (b) shall also specify the date on which the holders
of Common Stock shall be entitled to exchange their Common Stock, as the case
may be, for securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, share exchange, sale, transfer,
disposition, dissolution, liquidation or winding up, as the case may be.


                                  ARTICLE IV

                             Liquidating Dividends

     If the Company declares or pays a dividend upon the Common Stock payable
otherwise than in cash out of earnings or earned surplus (determined in
accordance with generally accepted accounting principles, consistently applied)
except for a stock dividend payable in shares of Common Stock (a "Liquidating
Dividend"), then the Company shall pay to the Holder of this Warrant at the time
of payment thereof the Liquidating Dividend which would have been paid to such
Holder on the Common Stock had this Warrant been fully exercised immediately
prior to the date on which a record is taken for such Liquidating Dividend, or,
if no record is taken, the date as of which the record holders of Common Stock
entitled to such dividends are to be determined.

                                   ARTICLE V

                            Reporting Requirements

     5.1  Rule 144 and 144A Reporting Information.  With a view to making
available the benefits of certain rules and regulations of the SEC which may at
times permit the sale of the Warrant or Warrant Shares to the public or other

(A) a written statement by the Company as to its compliance with the reporting
requirements of such Rule 144 of the Securities Act and the Exchange Act, (B)
copies of all SEC filings made by the Company within the previous one (1) year
period and any press releases issued by the Company since the date of the last

Company.


                                  ARTICLE VI

                                 MISCELLANEOUS

     6.1  Entire Agreement.  This Warrant and the Purchase Agreement contains
the entire agreement between the Holder hereof and the Company with respect to
the Warrant Shares purchasable upon exercise hereof and supersedes all prior
arrangements or understandings with respect thereto.

     6.2  Governing Law.  This Warrant shall be governed by and construed in
accordance with the laws (other than the laws of conflicts) of the State of
Oklahoma.

     6.3  Amendment and Waiver.  Except as otherwise provided herein, the
provisions of the Warrants may be amended and the Company may take any action
herein prohibited, or omit to perform any act herein required to be performed by
it, only if the Company has obtained the written consent of the Holders of
Warrants representing a majority of the Warrant Shares obtainable upon exercise
of the Warrants; provided that no such action may change the Exercise

                                     -12-
<PAGE>
 
Price of the Warrants or the number of shares or class of stock obtainable upon
exercise of each Warrant.  Notwithstanding the foregoing, the Company may, at
its option, reduce the Exercise Price of the Warrants, increase the number of
shares of stock obtainable upon exercise of each Warrant, or extend the Term of
the Warrant for such period as it may determine.

     6.4  Illegality.  In the event that any one or more of the provisions
contained in this Warrant shall be determined to be invalid, illegal or
unenforceable in any respect for any reason, the validity, legality and
enforceability of any such provision in any other respect and the remaining
provisions of this Warrant shall not, at the election of the party for whom the
benefit of the provision exists, be in any way impaired.

     6.5  Copy of Warrant.  A copy of this Warrant shall be filed among the

delivered at, or sent by certified or registered mail to, the offices of the
Company at 5727 South Lewis Avenue, Suite 700, Tulsa, Oklahoma 74105, or such
other address within the continental United States of America as shall have been
furnished by the Company to the Holder of this Warrant.

     6.7  Limitation of Liability; Not Stockholders.  No provision of this
Warrant shall be construed as conferring upon the Holder hereof the right to
vote, consent, receive dividends or receive notices (other than as herein
expressly provided) in respect of meetings of stockholders for the election of
directors of the Company or any other matter whatsoever as a stockholder of the
Company. No provision hereof, in the absence of affirmative action by the holder
hereof to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the holder hereof, shall give rise to any liability of
such Holder for the purchase price of any shares of Common Stock or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

     6.8  Exchange, Loss, Destruction, etc. of Warrant.  Upon receipt of
evidence satisfactory to the Company of the loss, theft, mutilation or

destroyed or mutilated Warrant. Any warrant issued under the provisions of this
Section 7.8 in lieu of any Warrant alleged to be lost, destroyed or stolen, or
in lieu of any mutilated Warrant, shall constitute an original contractual
obligation on the part of the Company. This Warrant shall be promptly canceled
by the Company upon the surrender hereof in connection with any exchange or
replacement. The Company shall pay all taxes (other than securities transfer
taxes or income taxes) and all other expenses and charges payable in connection
with the preparation, execution and delivery of warrants pursuant to this
Section 7.8.

     6.9  Headings.  The Article and Section and other headings herein are for

Exhibit A
<PAGE>
 
     This Registration Rights Agreement (this "Agreement") is made and entered
into as of April ___, 1998, by and between Gothic Energy Corporation, an
Oklahoma corporation (the "Company"), and Chesapeake Gothic Corp., an Oklahoma
corporation (the "Purchaser").

     This Agreement is made pursuant to the Securities Purchase Agreement, dated
as of March 31, 1998, by and among the Company, the Purchaser and Chesapeake
Acquisition Corporation (the "Purchase Agreement"), relating to the sale by the
Company to the Purchaser of $50,000,000 in aggregate liquidation value of its
Senior Redeemable Preferred Stock, Series B, par value $.05 per share (the
"Preferred Stock"), along with warrants (the "Warrants") for the purchase of
2,439,246 shares (the "Warrant Shares") of its Common Stock, par value $.01 per
share ("Common Stock").  In order to induce the Purchaser to enter into the
Purchase Agreement, the Company has agreed to provide to the Purchaser and its
Affiliates (the "Holders") the registration rights set forth in this Agreement.
The execution of this Agreement is a condition to the obligations of the
Purchaser to purchase the Preferred Stock and Warrants under the Purchase
Agreement.

     In consideration of the foregoing, the parties hereto agree as follows:

     1.   Definitions. As used in this Agreement, the following capitalized
defined terms shall have the following meanings:

          "Affiliate" of any specified Person means any other Person which
directly or indirectly through one or more intermediaries controls, or is
controlled by, or is under common control with, such specified Person. For

used with respect to any Person, means the possession, directly or indirectly,
of the power to direct or cause the direction of the management or policies of
such Person, whether through the ownership of voting securities, by agreement or
otherwise; provided, however, that, beneficial ownership of at least 10% of the
voting securities of a Person shall be deemed to be control.

other federal agency at the time administering the Securities Act.

          "Preferred Stock" shall mean the Senior Redeemable Preferred Stock,

Preferred Stock; (iii) Preferred Stock which has been converted to Common Stock;
and (iv) any Common Stock issued or issuable at any time or from time to time in
respect of any of the interests specified in (i) through (iii) hereof upon a
stock split, stock dividend, recapitalization or other similar event involving
the Company, of any Holder, until such Registrable Securities are registered
pursuant to a Registration Statement or until such securities are able to be
sold under Rule 144(k) (or successor Rule) under the Securities Act without
restriction.

Expenses (as defined below), incurred by the Company in complying with this

filing fees, exchange listing fees, printing expenses, escrow fees, fees and

     2.   Demand Registrations.

          (a)  Registration of Immediate Offering.  At any time after September
30, 1998, the Holders of at least 50% of the Registrable Securities (hereinafter
the "Majority Holders") may request registration by the Company under the
Securities Act of the resale by such Holders of all or any portion of their
Registrable Securities (an "Immediate Offering Registration"); provided,
however, that, with respect to Common Stock, such request for registration
includes such number of shares equal to or greater than 5% of the issued and
outstanding shares of Common Stock on the date of request; and provided further,
that, with respect to Preferred Stock, such request for registration includes
such number of shares equal to or greater than 50% of the issued and outstanding
shares of Preferred Stock on the date of request. A request for an Immediate
Offering Registration shall specify the approximate number of Registrable
Securities requested to be registered by the requesting Holders. Within 10 days
after receipt of such request, the Company shall give written notice of such
requested registration to all other Holders of Registrable Securities and shall
include in such registration all Registrable Securities with respect to which
the Company has received written requests for inclusion therein within 30 days
after delivery of the Company's notice.

          (b)  Registration of Delayed or Continuous Offering.  At any time
after September 30, 1998, the Majority Holders may request registration by the
Company under the Securities Act of all or any portion of their Registrable
Securities for resale in a delayed or continuous offering to the extent
permitted by Rule 415 (or any successor rule thereto) under the Securities Act
(a "Shelf Registration"). A registration statement for a Shelf Registration
shall


                                      -2-
<PAGE>
 
provide for resale by the Holders in the manner or manners designated in writing
to the Company by them (including, without limitation, one or more underwritten
offerings). Within 10 days after the receipt of such request, the Company shall
give similar written notice of such requested registration to all other Holders
of Registrable Securities and shall include in such registration all Registrable
Securities with respect to which the Company has received written requests for
inclusion therein within 30 days after delivery of the Company's notice.

          (c)  Number of Demand Registrations.  The Majority Holders shall be
entitled to request two (2) Immediate Offering Registrations; provided, a
registration shall not count as one of the permitted Immediate Offering
Registrations until it has become and remained effective for the prescribed time
period.  In addition, the Majority Holders shall be entitled to one (1) Shelf
Registration; provided, a registration shall not count as the permitted Shelf
Registration until it has become and remained effective for the prescribed time
period.  For purposes of this Agreement, an Immediate Offering Registration and
a Shelf Registration shall each constitute and be referred to as "Demand
Registration."

          (d)  Priority on Demand Registrations.  The Company shall not include
in any Demand Registration any securities which are not Registrable Securities
without the prior written consent of the Holders of at least 75% of the
Registrable Securities initially requesting such registration. If a Demand
Registration is an underwritten offering and the managing underwriters advise
the Company in writing that in their opinion the number of Registrable
Securities and, if permitted hereunder, other securities requested to be
included in such offering exceeds the number of shares, if any, which can be
sold in an orderly manner in such offering within a price range acceptable to
the Majority Holders initially requesting registration, subject, however, to the
terms of any other agreement entered into prior to the date hereof to which the
Company shall be a party, the Company shall include in such registration prior
to the inclusion of any securities which are not Registrable Securities the
number of Registrable Securities requested to be included which in the opinion
of such underwriters can be sold in an orderly manner within the price range of
such offering, pro rata among the respective Holders of Registrable Securities,
on the basis of the amount of shares requested for inclusion by each such
Holder, then, after the inclusion of all such Registrable Securities, the
Company shall include any other securities requested for inclusion.

          (e)  Selection of Underwriters.  The Majority Holders initially
requesting registration in any Demand Registration hereunder shall have the
right to select the investment banker(s) and manager(s) to administer the
offering, subject to the Company's approval which shall not be unreasonably
withheld.

     3.  Piggyback Registrations.

          (a)  Right to Piggyback.  At any time after September 30, 1998,
whenever the Company proposes to register any of its securities under the
Securities Act (other than pursuant


                                      -3-
<PAGE>
 
to a registration on Form S-4 or Form S-8) and the registration form to be used
may be used for the registration of Registrable Securities (a "Piggyback
Registration"), the Company shall give prompt written notice (in any event
within five (5) business days after its receipt of notice of any exercise of
demand registration rights other than under this Agreement) to all Holders of
Warrants or Registrable Securities of its intention to effect such a
registration and shall include in such registration all Registrable Securities
with respect to which the Company has received written requests for inclusion
therein within 30 days after the receipt of the Company's notice.

          (b)  Priority on Primary Registrations.  If a Piggyback Registration
is an underwritten primary registration on behalf of the Company, and the
managing underwriters advise the Company in writing that in their opinion the
number of securities requested to be included in such registration exceeds the
number which can be sold in an orderly manner in such offering within a price
range acceptable to the Company, the Company shall include in such registration,
subject, however, to the terms of any other agreement entered into prior to the
date hereof to which the Company shall be a party, (i) first, the securities the
Company proposes to sell, (ii) second, the Registrable Securities requested to
be included in such registration, subject to pro rata cut back among the Holders
thereof, and (iii) third, other securities requested to be included in such
registration.

          (c)  Priority on Secondary Registrations.  If a Piggyback Registration
is an underwritten secondary registration on behalf of holders of the Company's
securities, and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the holders initially requesting
such registration, the Company shall include in such registration, subject,
however, to the terms of any other agreement entered into prior to the date
hereof to which the Company shall be a party, (i) first, the securities
requested to be included therein by the holders requesting such registration,
(ii) second, the Registrable Securities requested to be included in such
registration, pro rata among the Holders of such securities on the basis of the
number of securities so requested to be included therein, and (iii), third,
other securities requested to be included in such registration.

          (d)  Right of Holder to Withdraw.  A Holder who has given notice to
the Company under Section 3(a) requesting inclusion of any Registrable
Securities in a Piggyback Registration shall, on five (5) business days notice
to the Company, have the right to withdraw its Registrable Securities from the
Piggyback Registration.

          (e)  Right of Company to Withdraw.  The Company shall, on five
business days notice to all holders who have given notice to the Company under
Section 3(a) requesting inclusion of their Registrable Securities in a Piggyback
Registration have the right to withdraw any registration statement filed
pursuant to this Section 3 for a Piggyback Registration at any time prior to the
effective date thereof.

     4.   Maintaining Effectiveness of Registration Statement.

          (a)  The Company shall use its reasonable best efforts to keep any
registration statement prepared and filed pursuant to this Agreement
continuously effective under the Securities Act from the initial effectiveness
thereof until the earliest to occur of (i) the date when all Registrable
Securities registered thereunder have been sold in the manner set forth and as
contemplated in the registration statement, or (ii) the date when counsel to the
Company or other counsel of such Holders' choosing shall render an opinion
addressed to the Holders whose Registrable Securities are registered thereunder,
to the effect that all remaining Registrable Securities are freely transferable
in the open market without limitations as to volume and manner of sale, and
without being required to file any forms or reports with the Commission under
the Securities Act or the rules and regulations thereunder of the Company (such
period being referred to as the "Effectiveness Period").

          (b)  If the registration statement filed pursuant to this Agreement
ceases to be effective for any reason at any time during the Effectiveness
Period, the Company shall use its reasonable best efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof, and in any event
shall within 45 days of such cessation of effectiveness amend such registration
statement in a manner reasonable expected to obtain the withdrawal of the order
suspending the effectiveness thereof, or file an additional registration
statement covering all of the Registrable Securities originally registered.  If
an additional registration statement is filed, the Company shall use its
reasonable best efforts to cause such registration statement to be declared
effective as soon as practicable after such filing and to keep such registration
statement continuously effective for the remainder of the Effectiveness Period.

     5.   Expenses of Registration. All Registration Expenses shall be borne by
the Company. Unless otherwise stated herein, all Selling Expenses relating to
securities registered on behalf of the Holders shall be borne by the Holders.
The Company shall pay all Registration Expenses in connection with any
registration initiated under this Article whether or not it has become effective
and whether or not such registration has counted as one of the permitted
registrations.

     6.   Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant hereto, the Company
will keep the Holders advised in writing as to the initiation of each
registration, qualification and compliance and as to the completion thereof. At
its expense, the Company will:

          (a)  Prepare and file with the Commission a registration statement
with respect to such securities and use its commercially reasonable efforts to
cause such registration statement to become and remain effective until the
distribution described in such registration statement has been completed;


                                      -5-
<PAGE>
 
          (b)  Notify each Holder of Registrable Securities of the effectiveness
of each registration statement filed hereunder and prepare and file with the
Commission such amendments and supplements to such registration statement and
the prospectus used in connection therewith as may be necessary to keep such
registration statement effective for the period of time set forth in Section 4,
as applicable, and to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended methods of
disposition by the sellers thereof set forth in such registration statement.

          (c)  Furnish to each Holder such number of copies of the registration
statement, each supplement and amendment thereto, and the prospectus included
therein, including a preliminary prospectus, in conformity with the requirements
of the Securities Act, and such other documents as such Holder may reasonably
request in order to facilitate the public sale of the shares by such Holder, and
promptly furnish to each Holder notice of any stop-order or similar notice
issued by the Commission or any state agency charged with the regulation of
securities, and notice of any Nasdaq or securities exchange listing.

          (d)  Use its reasonable best efforts to register or qualify such
Registrable Securities under the securities or blue sky laws of such
jurisdictions as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller.

          (e)  Use its best efforts to cause the Warrant Shares, together with
any shares of Common Stock issuable upon such conversion of Preferred Stock, to
be listed on the Nasdaq SmallCap Market or such other Securities Exchange on
which the Common Stock is approved for listing.

          (f)  Notify each seller of such Registrable Securities, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the existence of facts or the happening of any event (without
necessarily identifying such facts or event to such sellers) as a result of
which the prospectus included in such registration statement contains an untrue
statement of a material fact or omits any fact necessary to make the statements
therein not misleading, and, at the request of any such seller, the Company
shall prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such
prospectus shall not contain an untrue statement of a material fact or omit to
state any fact necessary to make the statements therein not misleading.

          (g)  Enter into such customary agreements (including underwriting
agreements in customary form) and take all such other actions as the Majority
Holders of the Registrable Securities being sold or the underwriters, if any,
reasonably request in order to expedite or 


                                      -6-
<PAGE>
 
facilitate the disposition of such Registrable Securities in any underwritten
offering of Registrable Securities.

          (h)  Make available for reasonable inspection by any seller of
Registrable Securities, any underwriter participating in any disposition
pursuant to such registration statement and any attorney, accountant or other
agent retained by any such seller or underwriter, such financial and other
records, corporate documents and properties of the Company as are customarily
made available to such persons on a confidential basis by the issuer in
connection with a registered public offering of securities similar to the
Registrable Securities, and cause the Company's officers, directors, employees
and independent accountants to supply all information reasonably requested by
any such seller, underwriter, attorney, accountant or agent in connection with
such registration statement.

          (i)  Otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering the
period of at least twelve months beginning with the first day of the Company's
first full calendar quarter after the effective date of the registration
statement, which earnings statement shall satisfy the provisions of Section
11(a) of the Securities Act and Rule 158 thereunder.

     7.   Indemnification.

          (a)  To the extent permitted by law, the Company will indemnify each
Holder, each of their respective officers and directors and partners, and each
person controlling a Holder within the meaning of the Securities Act, with
respect to which registration, qualification or compliance has been effected
pursuant to this Agreement, and each underwriter, if any, and each person who
controls any underwriter within the meaning of the Securities Act, against all
expenses, claims, losses, damages or liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, to the extent such expenses, claims,
losses, damages or liabilities arise out of or are based on any untrue statement
(or alleged untrue statement) of a material fact contained in any registration
statement, prospectus, offering circular or other similar document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, or any violation by the Company of the Securities Act or any
rule or regulation promulgated under the Securities Act applicable to the
Company in connection with any such registration, qualification or compliance,
and the Company will reimburse each Holder, each of their respective officers
and directors and partners, and each person controlling a Holder, each such
underwriter and each person who controls any such underwriter, for any legal and
any other expenses reasonably incurred in connection with investigating,
preparing or defending any such claim, loss, damage, liability or action;
provided, however, that the indemnity contained herein 


                                      -7-
<PAGE>
 
shall not apply to amounts paid in settlement of any claim, loss, damage,
liability or expense if settlement is effected without the consent of the
Company (which consent shall not unreasonably be withheld); provided, further,
that the Company will not be liable in any such case to the extent that any such
claim, loss, damage, liability or expense arises out of or is based on any
untrue statement or omission or alleged untrue statement or omission, made in
reliance upon and in conformity with written information furnished to the
Company by the Holders or such controlling person specifically for use therein.
Notwithstanding the foregoing, insofar as the foregoing indemnity relates to any
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) made in the preliminary prospectus but eliminated or remedied in the
amended prospectus on file with the Commission at the time the registration
statement becomes effective or in the final prospectus filed with the Commission
pursuant to the applicable rules of the Commission or in any supplement or
addendum thereto, the indemnity agreement herein shall not inure to the benefit
of any underwriter if a copy of the final prospectus filed pursuant to such
rules, together with all supplements and addenda thereto, was not furnished to
the person or entity asserting the loss, liability, claim or damage at or prior
to the time such furnishing is required by the Securities Act.

          (b)  To the extent permitted by law, each Holder will, if securities
held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected pursuant to terms
hereof, severally but not jointly, indemnify the Company, each of its directors
and officers, each person who controls the Company or such underwriter within
the meaning of the Securities Act, and each other person selling the Company's
securities covered by such registration statement, each of such person's
officers and directors and each person controlling such persons within the
meaning of the Securities Act, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by such Holder of any rule or regulation
promulgated under the Securities Act applicable to such Holder and relating to
action or inaction required of such Holder in connection with any such
registration, qualification or compliance, and will reimburse the Company, such
other persons, such directors, officers, persons, or control persons for any
legal or other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action, in each case to the
extent, but only to the extent, that such untrue statement (or alleged untrue
statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished to the Company by such Holder
specifically for use therein; provided, however, that the indemnity contained
herein shall not apply to amounts paid in settlement of any claim, loss, damage,
liability or expense if settlement is effected without the consent of such
Holder (which consent shall not be unreasonably withheld). Notwithstanding the
foregoing, the liability of such Holder under this subsection (b) shall be
limited in an amount equal to the net proceeds from the sale of Registrable
Securities 


                                      -8-
<PAGE>
 
sold by such Holder, unless such liability arises out of or is based on willful
conduct by such Holder. In addition, insofar as the foregoing indemnity relates
to any such untrue statement (or alleged untrue statement) or omission (or
alleged omission) made in the preliminary prospectus but eliminated or remedied
in the amended prospectus on file with the Commission at the time the
registration statement becomes effective or in the final prospectus filed
pursuant to applicable rules of the Commission or in any supplement or addendum
thereto, the indemnity agreement herein shall not inure to the benefit of the
Company if a copy of the final prospectus filed pursuant to such rules, together
with all supplements and addenda thereto, was not furnished to the person or
entity asserting the loss, liability, claim or damage at or prior to the time
such furnishing is required by the Securities Act.

          (c)  Notwithstanding the foregoing subsections (a) and (b), each party
entitled to indemnification under this Section 7 (the "Indemnified Party") shall
give notice to the party required to provide indemnification (the "Indemnifying
Party") promptly after such Indemnified Party has actual knowledge of any claim
as to which indemnity may be sought, and shall permit the Indemnifying Party to
assume the defense of any such claim or any litigation resulting therefrom,
provided that counsel for the Indemnifying Party, who shall conduct the defense
of such claim or litigation, shall be approved by the Indemnified Party (whose
approval shall not unreasonably be withheld), and the Indemnified Party may
participate in such defense at such party's expense, and provided further that
the failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Agreement unless
the failure to give such notice is materially prejudicial to an Indemnifying
Party's ability to defend such action and provided further, that the
Indemnifying Party shall not assume the defense for matters as to which there is
a conflict of interest or as to which the Indemnifying Party is asserting
separate or different defenses, which defenses are inconsistent with the
defenses of the Indemnified Party (in which case the Indemnifying Party shall
pay for one separate counsel for those Indemnified Parties with whom such
conflict exists). No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation. No Indemnified Party shall consent to entry of any judgment or enter
into any settlement without the consent of each Indemnifying Party. The failure
of an Indemnifying Party to give notice to the Indemnified Party of its election
to assume and control the defense of any action for which notice has been given
to the Indemnifying Party in accordance with this paragraph within 30 days after
receipt of such notice shall constitute an election by the Indemnifying Party
not to assume and control the defense of such action. An Indemnifying Party who
is not entitled to, or elects not to, assume the defense of a claim shall not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such Indemnifying Party with respect to such claim, unless in the
reasonable judgment of any Indemnified Party a conflict of interest may exist
between such Indemnified Party and any other of such Indemnified Parties or the
Indemnifying 


                                      -9-
<PAGE>
 
Party with respect to such claim, in which event the Indemnifying Party shall be
obligated to pay the fees and expenses of one separate counsel for such
Indemnified Parties.

          (d)  If the indemnification provided for in this Section 7 is
unavailable to an Indemnified Party in respect of any losses, claims, damages or
liabilities referred to therein, then each Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company, on the one hand, and each respective
shareholder offering securities in the offering (the "Selling Security Holder"),
on the other, from the offering of the Company's securities, or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company, on
the one hand, and each Selling Security Holder, on the other, in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative benefits received by the Company, on the one hand, and each Selling
Security Holder, on the other, shall be the net proceeds from the offering
(before deducting expenses) received by the Company, on the one hand, and each
Selling Security Holder, on the other. The relative fault of the Company, on the
one hand, and each Selling Security Holder, on the other, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by such Selling Security
Holder and the parties' relevant intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
each Selling Security Holder agree that it would not be just and equitable if
contribution pursuant to this Section were based solely upon the number of
entities from whom contribution was requested or by any other method of
allocation which does not take account of the equitable considerations referred
to above in this Section. Notwithstanding the provisions of this Section, no
Selling Security Holder shall be required to contribute any amount or make any
other payments under this Agreement which in the aggregate exceed the proceeds
received by such Selling Security Holder. No person guilty of fraudulent
misrepresentation (within the meaning of the Securities Act) shall be entitled
to contribution from any person who was not guilty of such fraudulent
misrepresentation.

          (e)  The indemnification provided for under this Agreement shall
remain in full force and effect regardless of any investigation made by or on
behalf of the Indemnified Party or any officer, director or controlling person
of such Indemnified Party and shall survive the transfer of securities.

     8.   Certain Information.

          (a)  Each Holder agrees, with respect to any Registrable Securities
included in any registration, to furnish to the Company such information
regarding such Holder, the 


                                     -10-
<PAGE>
 
Registrable Securities and the distribution proposed by such Holder as the
Company may reasonably request in writing and as shall be required in connection
with any registration, qualification or compliance referred to herein.

          (b)  The failure of a Holder to furnish the information requested
pursuant to this Section shall not affect the obligation of the Company to any
other selling security holders who furnish such information unless, in the
reasonable opinion of counsel to the Company, such failure impairs or may impair
the legality of the Registration Statement or the underlying offering.

     9.   Miscellaneous.

          (a)  No Inconsistent Agreements. The Company has not entered into nor
will the Company on or after the date of this Agreement enter into any agreement
which is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder do not in any way conflict with and
are not inconsistent with the rights granted to the holders of the Company's
other issued and outstanding securities, if any, under any such agreements.

          (b)  Amendments and Waivers. The provisions of this Agreement,
including the provisions of this paragraph, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate number of the outstanding Registrable
Securities affected by such amendment, modification, supplement, waiver or
consent; provided, however, a waiver or consent to departure from the provisions
hereof that relates exclusively to the rights of Holders of Registrable
Securities whose securities are being sold pursuant to a Registration Statement
and that does not directly or indirectly affect the rights of other Holders of
Registrable Securities may be given by the Holders of a majority of the
Registrable Securities proposed to be sold.

          (c)  Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, registered first-
class mail, telex, telecopier, or any courier guaranteeing overnight delivery
(i) if to a Holder, at the most current address given by such Holder to the
Company by means of a notice given in accordance with the provisions of this
Section 9(c), which address initially is, with respect to each Purchaser, the
address set forth in the Purchase Agreement; and (ii) if to the Company,
initially at the Company's address set forth in the Purchase Agreement and
thereafter at such other address, notice of which is given in accordance with
the provisions of this Section 9(c).

an Oklahoma corporation ("Gothic Production").


                             W I T N E S S E T H :


  WHEREAS, Gothic and Chesapeake Energy Corporation, an Oklahoma corporation,
entered into that certain letter of intent dated March 18, 1998 (the "Letter of
Intent"), in order to provide funding to allow the Gothic Parties to fund the
development of the Gothic Parties' oil and gas interests (the "Financing

"Preferred Stock"), (ii) issuing warrants for Gothic common stock to Chesapeake,
(iii) conveying to Chesapeake fifty percent (50%) of the Gothic Parties' oil and
gas assets in the Arkoma Basin and (iv) conveying to Chesapeake fifty percent
(50%) of the Gothic Parties' undeveloped oil and gas assets in the Participation
Area;

  WHEREAS, Gothic, Gothic Texas and Gothic Production together with various
affiliate corporations, partnerships, limited liability companies and other
entities (jointly and severally the "Gothic Parties") own as of the date of this
Agreement interests in oil, gas and mineral leases (the "Existing Acreage")
covering lands located in whole or in part in Oklahoma, Texas, New Mexico,
Arkansas and Kansas including, without implied limitation, the oil, gas and
mineral leases described at Schedule "A" attached as a part hereof;

  WHEREAS, as part of the Financing Transaction and subject to the terms and
conditions of this Agreement, Chesapeake has agreed to acquire and Gothic has
agreed to convey to Chesapeake on the terms set forth in this Agreement an
undivided fifty percent (50%) interest in the Existing Acreage, the Related
Interests (as hereinafter defined) and the Acquisition Acreage (as hereinafter
defined); and

  WHEREAS, Gothic and Chesapeake also desire to provide for the development of
all of the Existing Acreage, the Related Interests and the Acquisition Acreage
(collectively, the "Gothic Interests") covering lands (the "Participation Area")
located in whole or in part in Oklahoma, Texas, New Mexico, Arkansas and Kansas,
but excluding lands described as the Pecos Slope Acreage as outlined in the plat

  NOW, THEREFORE, in consideration of the mutual covenants and promises
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:
<PAGE>
 
1.   Sale. The purchase and sale of the Existing Acreage and the Related
Interests will be consummated on the following terms:

     1.1  Existing Acreage. The Gothic Parties agree to sell and Chesapeake
          agrees to purchase an undivided fifty percent (50%) interest of the
          Gothic Parties' right, title and interest in and to the Existing
          Acreage as of the date of this Agreement less and except: (a) the
          interest of the Gothic Parties in any existing wellbore which on the
          date of the Letter of Intent was producing oil and gas in commercial
          quantities which interest includes oil, gas and other hydrocarbons
          produced from such well bore and any revenue related thereto; (b) the
          interest of the Gothic Parties in the wellbore of wells drilling and
          or completed as of the date of this Agreement which are listed at
          Schedule 1.1 attached as a part hereof which interest includes oil,
          gas and other hydrocarbons produced from such wellbore and any revenue
          related thereto; and (c) any Gothic Interest that is covered by that
          certain Oil and Gas Asset Purchase Agreement of even date herewith
          between Chesapeake and Gothic covering oil and gas interests in the
          Arkoma Basin (the "Arkoma Purchase Agreement"). Notwithstanding the
          foregoing, the Gothic Parties agree to convey to Chesapeake a non-
          exclusive easement to utilize for the further development of the
          Gothic Interests any such producing wellbore that the Gothic Parties
          intend to plug or abandon. For purposes of this Agreement a well will
          be deemed to be "producing oil and gas in commercial quantities" if
          such well has produced or is capable of producing oil and gas in
          sufficient quantities to yield a return in excess of lifting expenses
          for the ninety (90) days prior to the determination date.

     1.2  Related Interests. The Gothic Parties agree to sell and Chesapeake
          agrees to purchase an undivided fifty percent (50%) interest of the

          Interests as of the date of this Agreement less and except: (a) any
          interest of the Gothic Parties in any wellbore which on the date of
          the Letter of Intent was producing oil and gas in commercial
          quantities which interest includes oil, gas and other hydrocarbons
          produced from such well bore and any revenue related thereto; (b) the
          interest of the Gothic Parties in the wellbore of wells drilling and
          or completed as of the date of this Agreement which are listed at
          Schedule 1.1 attached as a part hereof which interest includes oil,
          gas and other hydrocarbons produced from such wellbore and any revenue
          related thereto; and (c) any Gothic Interest that is covered by the
          Arkoma Purchase Agreement. For purposes of this Agreement "Related
          Interests" means a non-cost bearing interest in oil, gas and other
          hydrocarbons owned by the Gothic Parties on the date of this Agreement
          which covers lands located in whole or in part in: (a) a governmental
          production unit containing Existing Acreage; and (b) lands covered by
          the Existing Acreage. The term Related Interests also includes,
          without implied limitation, mineral interests, royalty interests,
          overriding royalty interests, net profits interests, production
          payments, any such interests acquired from Amoco Production Company
          under that certain Purchase and Sale Agreement with Gothic dated

          at Schedule "1.2" attached as a part hereof.

     1.3  Reconveyance Obligation. Effective on April 30, 2003, (the
          "Reconveyance Date"), Chesapeake hereby agrees to reconvey to the
          Gothic Parties any Gothic Interests conveyed to Chesapeake under
          paragraphs 1.1 or 1.2 of this Agreement other than the Gothic
          Interests that: (a) cover any lands included in a governmental
          production unit for a Proposed Well (as hereinafter defined) proposed
          prior to the Reconveyance Date and spudded prior to December 31, 2003;
          (b) cover any lands included in a governmental production unit for any

          right to conduct drilling or mining operations therein are bound to
          share investment and operating costs on a specified basis. A
          governmental production unit may be formed by agreement or by order of
          an agency of the state or federal government empowered to do so and
          includes drilling units, spacing units, pooled units and proration
          units.

2.   Additional Purchase Price. In addition to the Financing Transaction and any

          reasonably requested by Chesapeake. The foregoing information will be
          made available to Chesapeake for review and photocopying. At
          Chesapeake's option, to be exercised within fifteen (15) days after
          receipt of a complete Acquisition Notice, Chesapeake will have the
          right to acquire up to an undivided fifty percent (50%) interest in
          the Acquisition Acreage acquired or to be acquired by the Gothic
          Parties. The purchase price (the "Acquisition Price") for the
          Acquisition Acreage to be acquired by Chesapeake will be the amount
          equal to the portion of the Acquisition Costs equal to the percentage
          of the Acquisition Acreage which Chesapeake elects to acquire under
          this paragraph 7.2.

     7.3  Acquisition Acreage. As used in this Agreement "Acquisition Acreage"
          will mean and include any and all right, title or interest acquired by
          the Gothic Parties in any manner (whether owned directly, indirectly,
          beneficially or otherwise) in and to the following property,
          contractual or other interests located in whole or in part within the
          Participation Area: (i) any right of, contract for or lease for the
          development and/or production of oil, gas and other hydrocarbons
          including, without limitation, leasehold interests, working interests,
          net revenue interests, overriding royalty interests, net profits
          interests and production payments; (ii) any mineral, royalty or non-
          participating royalty interests; (iii) any interests of the type
          described in (i) or (ii) which may be earned or acquired by conducting
          drilling, seismic or other operations or activities; and (iv) any
          ownership interest in, indebtedness of and any option or other right
          to acquire any of the foregoing in any person which owns any of the
          foregoing interests in oil, gas and other hydrocarbons which are
          located in whole or in part in the Participation Area including,
          without implied limitation, any stock in any person, any membership
          interests in partnerships or limited liability companies or interests
          in business trusts.

                                      -11-

     7.4  Acquisition Costs. As used in this Agreement "Acquisition Costs" means
          the sum of the amounts paid to unaffiliated third parties for: (a)
          leases or interests in oil and gas, including, but not limited to
          bonuses, brokers' commissions, geological consulting fees, engineering
          fees and the costs of any equipment or other assets purchased in
          conjunction with the acquisition of such leases; (b) title insurance
          or title examination costs, filing fees, recording costs, transfer
          taxes, if any, and like charges in connection with the acquisition of
          such leases; and (c) geological, geophysical, seismic, land,
          engineering, drafting, accounting, legal and other like costs and
          expenses incurred in connection with the acquisition of such leases.
          As soon as practical after delivery of an Acquisition Notice, but in
          any event not later than five (5) business days prior to the payment
          of the Acquisition Price by Chesapeake, the Gothic Parties will
          deliver to Chesapeake documentation supporting the calculation of the
          Acquisition Costs for verification by Chesapeake.

     7.5  Acquisition Closings. In the event Chesapeake elects to acquire all or
          part of the Acquisition Acreage covered by an Acquisition Notice,
          within fifteen (15) days after Chesapeake provides the notice of its
          election to participate (or the next business day, if such day does
          not fall on a business day) the acquisition will be closed by
          Chesapeake paying the Acquisition Price for such Acquisition Acreage
          and the Gothic Parties assigning to Chesapeake the Acquisition Acreage
          to be acquired by Chesapeake by delivering an assignment in
          substantially the form attached at Schedule "7.5" attached as a part
          hereof. Chesapeake will record such assignment with appropriate
          governmental authorities at Chesapeake's expense. If the Gothic
          Parties are waiting on a farmout or third party assignment, the Gothic
          Parties will make the assignment to Chesapeake within twenty (20) days
          after the Gothic Parties receive such farmout or assignment or at
          Chesapeake's request direct such assignment to be made by the seller
          of the Acquisition Acreage directly to Chesapeake.

8.   Chesapeake AMI Acquisitions. Chesapeake and the Gothic Parties agree to the
creation of the area of mutual interest (the "Chesapeake AMI") covering the
Gothic Parties' current 3D seismic projects in Oklahoma in the East Cement
Field, the West Cement Field, the Coyote Hill Prospect, the Northern Canadian
Prospect and the Calumet Prospects as outlined at Schedule "8" attached as a
part hereof and the right of the Gothic Parties to participate in future
acquisitions on the following terms:

     8.1  Gothic Parties' Option. Chesapeake hereby grants to the Gothic Parties
          as a group the option to purchase up to an undivided fifty percent
          (50%) interest in Chesapeake Acreage (as hereinafter defined) to be
          acquired by Chesapeake pursuant to an agreement entered into with an
          unaffiliated third party after the Closing Date reduced by any
          existing or future area of mutual interest agreement which Chesapeake
          enters into with an unaffiliated third party covering all or part of
          the Chesapeake Acreage. If Chesapeake or any affiliate of Chesapeake
          enters into a definitive agreement or contract during the term of this
          Agreement providing for the acquisition of any Chesapeake Acreage in
          the Chesapeake AMI, Chesapeake will give written notice to the Gothic
          Parties of the acquisition within ten (10) days after such agreement
          is executed and the earnest money deposit, if 

                                      -12-
<PAGE>
 
          any, is paid by Chesapeake (a "CGC Acquisition Notice"). The CGC
          Acquisition Notice will set forth and include: (a) the location of all
          of the Chesapeake Acreage as reflected on an accompanying plat; (b) an
          itemized statement of CGC Acquisition Costs (as hereinafter defined)
          and amount of acreage covered by the CGC Acquisition Notice; (c) the
          date of the acquisition and a copy of any letters of intent, purchase
          contracts, agreements, mineral leases and assignments; (d) all of the
          terms of such acquisition (including leasehold burdens and drilling
          commitments); (e) all title information in the possession of or
          available to Chesapeake; and (f) and any other information reasonably
          requested by the Gothic Parties. The foregoing information will be
          made available to the Gothic Parties for review and photocopying. At
          the Gothic Parties' option, to be exercised within fifteen (15) days
          after receipt of each CGC Acquisition Notice, the Gothic Parties will
          have the right to acquire up to an undivided fifty percent (50%)
          interest in the Chesapeake Acreage acquired by Chesapeake as reduced
          by any existing or future area of mutual interest agreement which
          Chesapeake enters into with an unaffiliated third party covering all
          or part of the Chesapeake Acreage. The purchase price (the "Gothic
          Price") for the Chesapeake Acreage to be acquired by the Gothic
          Parties will be the amount equal to the portion of the CGC Acquisition
          Costs equal to the percentage of the Chesapeake Acreage which the
          Gothic Parties elect to acquire under this paragraph 8.1.

     8.2  Definitions. As used in this Agreement "Chesapeake Acreage" will mean
          and include any and all right, title or interest acquired by
          Chesapeake or Chesapeake's affiliates in and to the following
          undeveloped interests in oil and gas located within the Chesapeake
          AMI: (a) any contract or lease for the development and/or production
          of oil, gas and other hydrocarbons including, without limitation,
          leasehold interests, working interests, net revenue interests,
          overriding royalty interests, net profits interests and production
          payments; (b) any mineral, royalty or non-participating royalty
          interests; and (c) any interests of the type described in (a) or (b)
          which may be earned or acquired by conducting drilling, seismic or
          other operations or activities. To qualify as Chesapeake Acreage the
          oil and gas interest (x) must be a direct undeveloped interest in oil
          and gas rather than an interest in a person, (y) cannot lie within the
          governmental production unit for a well producing oil and gas in
          commercial quantities in which Chesapeake is acquiring an interest in
          the same transaction and (z) must be acquired by Chesapeake directly
          from the landowner or from a person or company selling the oil and gas
          interest in the ordinary course of business pursuant to a farmout
          arrangement or pursuant to a pooling order entered by the appropriate
          governmental authority. As used in this Agreement "CGC Acquisition
          Costs" means any Acquisition Costs incurred by Chesapeake in the
          acquisition of Chesapeake Acreage.

     8.3  Acquisition Closings. In the event the Gothic Parties elect to acquire
          all or part of the Chesapeake Acreage covered by a CGC Acquisition
          Notice, within fifteen (15) days after the Gothic Parties provide
          their election to participate (or the next business day, if such day
          does not fall on a business day) the acquisition will be closed by the
          Gothic Parties paying the Gothic Price for such Chesapeake Acreage and
          Chesapeake assigning to the Gothic Parties the Chesapeake Acreage to
          be

                                      -13-
<PAGE>
 
          acquired by the Gothic Parties by delivering an assignment in
          substantially the form attached at Schedule "8.3" attached as a part
          hereof. The Gothic Parties will record such assignment with the
          appropriate governmental authorities at the Gothic Parties' expense.
          If Chesapeake is waiting on a farmout or third party assignment,
          Chesapeake will make the assignment to the Gothic Parties within
          twenty (20) days after Chesapeake receives such farmout or assignment
          or at the Gothic Parties' request direct such assignment to be made by
          the seller of the Chesapeake Acreage directly to the Gothic Parties.

9.   Lease Maintenance. During the term of this Agreement, except as otherwise
     provided herein, the Gothic Parties agree to maintain the Existing Acreage,
     the Related Interests and the Acquisition Acreage as follows:

     9.1  Maintenance. The Gothic Parties agree to take the actions necessary to
          maintain the oil and gas leases covering the Existing Acreage, the
          Related Interests and the Acquisition Acreage in which Chesapeake and
          the Gothic Parties own an interest in full force and effect for the
          respective terms thereof, including, without implied limitation,
          payment of delay rentals, taxes and other reasonable expenses
          (collectively, the "Maintenance Expenses") necessary to maintain the
          rights of Chesapeake and the Gothic Parties under the Existing
          Acreage, the Related Interests and the Acquisition Acreage. Not less
          than sixty (60) days prior to the date the Maintenance Expenses are
          due, the Gothic Parties will inform Chesapeake whether the Gothic
          Parties are going to take the actions necessary to maintain such
          Existing Acreage, Related Interests or Acquisition Acreage. In the
          event the Gothic Parties notify Chesapeake of the Gothic Parties'
          intent to take the actions necessary to maintain the Existing Acreage,
          the Related Interests or the Acquisition Acreage, within twenty (20)
          days after receipt of an invoice therefor, Chesapeake will: (a) pay to
          the Gothic Parties an amount equal to Chesapeake's proportionate share
          of such Maintenance Expenses based on Chesapeake's percentage
          ownership of the affected Existing Acreage, Related Interests and
          Acquisition Acreage; or (b) assign all of Chesapeake's interest in
          such Existing Acreage, Related Interests and Acquisition Acreage to
          the Gothic Parties pursuant to the form of assignment at Schedule
          "9.1A" attached as a part hereof. In the event the Gothic Parties
          decide not to maintain any Existing Acreage, Related Interests or
          Acquisition Acreage, within twenty (20) days after written request by
          Chesapeake, the Gothic Parties will assign all of the Gothic Parties'
          interest in such Existing Acreage, Related Interests or Acquisition
          Acreage to Chesapeake pursuant to the form of assignment at Schedule
          "9.1B" attached as a part hereof.

     9.2  Renewals; Re-leasing. If prior to the reconveyance by Chesapeake under
          paragraph 1.3 of this Agreement any of the Existing Acreage, the
          Related Interests or Acquisition Acreage is renewed or any of the
          acreage covered thereby is re-leased by the Gothic Parties, the Gothic
          Parties will offer Chesapeake its pro rata share thereof at a price
          equal to the Acquisition Costs for such renewal or re-leasing.

10.  Development. The Gothic Parties and Chesapeake agree to jointly develop and
     operate 

                                      -14-
<PAGE>
 
     the Existing Acreage, the Related Interests and the Acquisition Acreage on
     the terms and conditions set forth in this paragraph 10. From time to time
     during the term of this Agreement, either Chesapeake or the Gothic Parties
     (the "Proposing Party") may by written notice to the other party: (a)
     designate a governmental production unit from the Existing Acreage and/or
     the Acquisition Acreage (a "Prospect"); and (b) subject to the limitations
     in paragraph 10.6 propose the drilling and completion of one (1) or more
     wells on such Prospect (a "Proposed Well").

     10.1 Proposed Well Information. With respect to each Proposed Well, the
          Proposing Party will deliver to the other party to this Agreement (the
          "Receiving Party") a Proposed Well information package with the notice
          which will include the following: a brief geological presentation, a
          map designating the Prospect, an AFE for the Proposed Well, signature
          pages for the joint operating agreement (the "Joint Operating
          Agreement") for the Proposed Well and signature pages for the
          Memorandum of Joint Operating Agreement. The Joint Operating Agreement
          will be in the form at Schedule "10.1" attached as a part hereof.

     10.2 Participation Election. The Receiving Party will notify the Proposing
          Party in writing whether the Receiving Party elects to participate in
          the Proposed Well with all or part of the Receiving Party's interest
          in any Existing Acreage, Related Interests and Acquisition Acreage
          within fifteen (15) days after receipt of the Proposed Well
          information package, unless otherwise extended in writing by the
          Proposing Party. If the Receiving Party elects to participate in the
          Proposed Well, the Receiving Party will deliver to the Proposing
          Party: (a) an executed Joint Operating Agreement signature page for
          such Proposed Well; (b) an executed AFE for such Proposed Well; and
          (c) an executed Memorandum of Joint Operating Agreement for such well
          which will be promptly filed by the Proposing Party in the appropriate
          governmental office. In the event the Receiving Party is a Gothic
          Party and the Gothic Party elects not to participate with all or part
          of the Existing Acreage, Related Interests or Acquisition Acreage
          retained by the Gothic Parties (the "Retained Interest") in any
          Proposed Well or fails to elect to participate within the required
          time period, the Gothic Parties will be deemed to have: (i) elected
          not to participate in the Proposed Well; and (ii) agreed to farmout
          all of the Retained Interest included in the Prospect for such
          Proposed Well to Chesapeake at a net revenue interest equal to the
          existing net revenue interest of such Gothic Party with no overriding
          royalty interest being retained by the Gothic Party. The acreage
          earned pursuant to any such farmout will be limited to the Retained
          Interest included in the governmental production unit for the Proposed
          Well as finally approved by the appropriate governmental authority and
          will be deemed earned on the earlier of the completion of such well as
          a producing well or the drilling of such well to the total proposed
          depth. The Gothic Parties agree to assign to Chesapeake the interest
          earned under the foregoing farmout within thirty (30) days after such
          interest is earned and to execute such additional documents as
          Chesapeake, as the Proposing Party, reasonable requests to evidence
          and convey any farmouts earned pursuant to this Agreement including an
          outright assignment to Chesapeake of such interest coupled with an
          obligation to reconvey such interest if such interest is not earned in
          accordance with this paragraph 10.2.

                                      -15-
<PAGE>
 
     10.3  Resubmissions. In the event the Proposed Well is not spudded within
           one hundred eighty (180) days following the Receiving Party's
           election, or deemed election, to participate or not participate
           therein, the Receiving Party's election under paragraph 10.2 will be
           voided and the Proposing Party will be required to repropose such
           Proposed Well in accordance with this paragraph 10.3. On such
           reproposal the Receiving Party will be entitled to make a new
           election under paragraph 10.2 of this Agreement.

     10.4  Operations. Except for the Proposed Wells in which Chesapeake elects
           not to participate or a well containing Gothic Interests for which a
           third party not affiliated with the Gothic Parties was previously
           appointed and is continuing to act as the operator, Chesapeake will
           be appointed the operator on all Proposed Wells pursuant to the Joint
           Operating Agreement and the parties agree to vote all of their
           interests in such Proposed Well for Chesapeake as operator. With
           respect to each Proposed Well in which the Gothic Parties have
           elected to participate with at least twenty-five percent (25%) of the
           Existing Acreage and Acquisition Acreage in the Retained Interest for
           such well, the Gothic Parties will have the right to provide a
           request for a resignation to Chesapeake within five (5) days after
           the later of the following to occur: (a) first sale of production
           from such Proposed Well; or (b) the completion of all proposed
           drilling and completion of the Proposed Well as a producing oil or
           gas well. If the Gothic Parties and Chesapeake have sufficient votes
           together to ensure that a Gothic Party will be appointed as the
           operator of such Proposed Well, Chesapeake agrees to resign as the
           operator of such Proposed Well on the appointment of such Gothic
           Party as the operator of the Proposed Well which resignation and
           appointment will be effective on the first day of the month following
           the satisfaction of all the foregoing conditions. The right of the
           Gothic Parties to require Chesapeake to resign as operator will in no
           event apply to any wells now or hereafter drilled or operated in the
           Townships 4N-19E, 4N-20E, 5N-19E and 5N-20E except for Sections 1-7
           in Township 5N-19E in the Arkoma Basin. If the Gothic Party appointed
           as operator of a Proposed Well subsequently proposes to resign as the
           operator of such Proposed Well, the Gothic Parties agree to use the
           Gothic Parties' best efforts to cause Chesapeake or Chesapeake's
           designee to be appointed as successor operator including, without
           implied limitation, voting all of the Gothic Parties' interests in
           such Proposed Well for Chesapeake as successor operator.

     10.5  Third Party Wells. In the event an independent third party proposes a
           well in a governmental production unit that includes Retained
           Interests the Gothic Parties will within five (5) days after the
           Gothic Parties receive notice of the proposal provide written notice
           of the well proposal to Chesapeake and will, thereafter, notify
           Chesapeake in writing in not less than ten (10) days after the Gothic
           Parties receive the proposal if the Gothic Parties elect to
           participate in such third party well or elect not to participate in
           such third party well. For purposes of this Agreement the term
           Proposal includes any forced pooling action or other unitization by
           order of any governmental agency. In the event the Gothic Parties do
           not elect to participate with all or part of the Retained Interest in
           such well or fail to notify Chesapeake of the Gothic Parties'
           decision to participate within the 

                                      -16-
<PAGE>
 
           required time period, the Gothic Parties will at Chesapeake's
           election be deemed to have agreed to farmout the Retained Interest
           included in the Prospect for such third party well to Chesapeake on
           terms no less favorable to Chesapeake than the terms the third party
           proposing the well offered to the Gothic Parties in the initial
           written well proposal. Notwithstanding the foregoing, a well will not
           be a third party proposed well and will be deemed a Proposed Well and
           subsequent to the farmout provisions at paragraph 10.2 of this
           Agreement if: (a) Chesapeake or the Gothic Parties propose the well
           in accordance with this Agreement prior to receipt of the written
           well proposal from a third party; (b) after the well is proposed by
           the third party Chesapeake or the Gothic Parties are or have the
           right to become the operator of the well; or (c) the well is proposed
           by the third party at the instigation of the Gothic Parties or
           Chesapeake. The acreage earned pursuant to any such farmout will be
           limited to the Retained Interest included in the governmental
           production unit for the third party well as finally approved by the
           appropriate governmental authority and will be deemed earned on the
           earlier of the completion of such Proposed Well as a producing well
           or the drilling of such Proposed Well to the total proposed depth.
           The Gothic Parties agree to execute such additional documents as
           Chesapeake reasonably requests, to assign to Chesapeake the interest
           earned under the foregoing farmout within thirty (30) days after such
           interest is earned and to execute such additional documents as
           Chesapeake, reasonably requests to evidence and convey any farmouts
           earned pursuant to this Agreement including an outright assignment to
           Chesapeake of such interest coupled with an obligation to reconvey
           such interest if such interest is not earned in accordance with this
           paragraph. The Gothic Parties agree to cooperate with Chesapeake in
           order to permit Chesapeake to exercise the rights under this
           paragraph 10.5 including providing notice to Chesapeake of the Gothic
           Parties' election not to participate in such well in sufficient time
           for Chesapeake to elect to acquire such interest under this paragraph
           10.5.

     10.6  Limitations. The parties agree that the number of Proposed Wells to
           be proposed by Chesapeake under this paragraph 10 will be limited to

with respect thereto pursuant to this Agreement. Notwithstanding the foregoing,
any lease, contract or letter of intent entered into by the Gothic Parties prior
to the Termination Date, will be offered to Chesapeake in accordance with the

not an interest owner, any geological, geophysical, reservoir, engineering,

if any, done for each Proposed Well. With respect to any Proposed Well, if any
party makes or causes to be made logs, cores, formation tests, drill stem tests
or production or other tests, each will promptly furnish the results thereof to
the other party hereto. The Gothic Parties and Chesapeake will have access to
any Proposed Well, including the derrick floor, at all reasonable times, but at
the Gothic Parties' or Chesapeake's sole risk and expense, to witness all
activities conducted by the operator of such well. Unless otherwise mutually
agreed, the Gothic Parties and Chesapeake will have no less than twelve (12)
operations meetings per calendar year. In addition, Chesapeake will have access

employees (the "CGC Indemnified Parties") for, from and against all losses,
diminution in value, damages, claims, liabilities, debts, obligations and
expenses (including interest, reasonable legal fees, and expenses of litigation)

ownership thereof; (c) any of the wellbores or other interests and rights which

Parties prior to the date of this Agreement; and (e) any breach or default in
performance by the Gothic Parties of any covenant or obligation set forth in
this Agreement or any related document.  In addition to the foregoing, the
Gothic Parties will pay to the CGC Indemnified Parties interest on the amount of
any loss, damage, claim, liability, debt, obligation or expense the payment of
which is or becomes due to the CGC Indemnified Parties by the Gothic Parties,
such interest to be at a floating rate of interest equal to the prime rate
published from time to time in The Wall Street Journal.  The remedies provided
by this paragraph 18 are in addition to, and not in lieu of, such other remedies
as may be available under applicable laws.  Claims for indemnification will be
paid by the Gothic Parties within ten 

                                      -20-
<PAGE>

Parties.

Gothic Interests conveyed to Chesapeake under this Agreement or the operation
thereof and arising after such Gothic Interest is assigned or conveyed to
Chesapeake of record; and (b) any breach of default in performance by Chesapeake
of any covenant or obligation set forth in this Agreement or any related
document. In addition to the foregoing, Chesapeake will pay to the Gothic
Indemnified Parties interest on the amount of any loss, damage, claim,
liability, debt, obligation or expense the payment of which is or becomes due to
the Gothic Indemnified Parties by Chesapeake, such interest to be at a floating
rate of interest equal to the prime rate published from time to time in The Wall
Street Journal. The remedies provided by this paragraph 18 are in addition to,
and not in lieu of, such other remedies as may be available under applicable
laws. Claims for indemnification will be paid by Chesapeake within ten (10) days
after notification thereof.

19.  No Partnership. Neither this Agreement nor any other agreement between the
Gothic Parties and Chesapeake creates, nor will it be construed as creating, a
mining partnership, commercial partnership, partnership relationship or joint
venture. The liability of the parties hereto will be several and not joint or
collective. Each of the parties hereto elects under the Internal Revenue Code of
1986, as amended (the "Code"), to be excluded from the application of all of the
provisions of Subchapter K of Chapter 1 of Subtitle A of the Code. Subject to
the Gothic Parties' obligations under this Agreement to assign the Gothic
Interests to Chesapeake, the parties may engage in or possess any interest in
any other business venture of any nature or description, independently or with
others, including, but not limited to, the acquisition ownership, financing,
leasing, operation, or development of oil and gas interests. The Gothic Parties

           instruments to be delivered pursuant to the foregoing constitute the
           entire agreement between Chesapeake and the Gothic Parties relating
           to the sale and development of the Gothic Interests and there are no
           agreements, understandings, warranties or representations between the
           Gothic Parties and Chesapeake except as set forth therein. Neither
           this Agreement nor any of the provisions hereof can be changed,

           signed by the party against whom enforcement of the change, waiver,
           discharge or termination is sought. The failure by any party to
           insist on strict performance of the obligations created by this
           Agreement will not be a waiver of any right to demand strict
           compliance with this Agreement at any later time.

     20.3  Binding Effect. This Agreement will inure to the benefit of and bind
           the respective successors and permitted assigns of the parties

           the intention of the parties that if any such provision is held to be
           illegal, invalid or unenforceable, there will be added in lieu
           thereof a provision as similar in terms to such provision as is
           possible to make such provision legal, valid and enforceable.

     20.5  Counterpart Execution. This Agreement may be executed in
           counterparts, each of which will be deemed an original document but
           all of which will constitute a single document. This Agreement will
           not be binding on or constitute evidence of a contract between the
           parties until such time as a counterpart of this Agreement has been
           executed by each party and a copy thereof delivered to the other
           parties to this Agreement.

     20.6  Survival. The covenants, representations and warranties of the

           partnership. The descriptive headings of the paragraphs of this

           construction of the content of this Agreement. In the event of a

            the Purchaser will not obligate the Purchaser with respect to (or
            result in the assumption by the Purchaser of) any obligation of the

            any liability, agreement or commitment relating to the Properties
            including, without implied limitation, to pay to or share with any

            commitment, absolute or contingent, known or unknown, relating to or
            connected with the Properties; (b) neither the Purchaser nor the
            Properties will be subject to or liable for any claim, debt,

            the Purchaser from all such matters. The Seller has complied and
            will continue to comply with all applicable federal, state or local
            statutes, laws and regulations.

     3.5    Contracts. The Seller has delivered to the Purchaser true copies (or
            descriptions, in the case of oral agreements) of all of the
            contracts and agreements relating to the Properties, including,
            without limitation, all marketing and production sales contracts.
            Except as provided in Schedule 3.5 attached hereto as a part hereof
            no such marketing or production sales contracts will in any way
            prevent or hinder the Purchaser in taking in kind the Purchaser's
            share of production from the Properties. There are no other material
            contracts, commitments or agreements in effect related to the
            Properties that have not been disclosed to the Purchaser in writing.
            Except as set forth in Schedule "3.5," to the best of the Seller's
            knowledge: (a) such contracts and agreements are in full force and
            effect; (b) no event of default or event which would become an event
            of default with the giving of notice or passage of time has
            occurred; and (c) no condition presently exists which would give any
            party to any such contract the right to terminate such contract.
            There are no other material contracts, commitments or agreements in
            effect related to the Properties that have not been disclosed to the
            Purchaser in writing.

     3.6    Consents and Approvals. No notice to, filing with, or authorization,
            consent or approval of any governmental entity, person or other
            entity is necessary for the consummation of the transactions
            contemplated by this Agreement. The execution, delivery, performance
            and consummation of this Agreement does not and will not: (a)
            violate, conflict with or constitute a default or an event that,
            with notice or lapse of time or both, would be a default, breach or
            violation under any term or provision of any instrument, agreement,
            contract,

                                      -4-
<PAGE>
 
            commitment, license, promissory note, conditional sales contract,
            indenture, mortgage, deed of trust, lease or other agreement,
            instrument or arrangement to which the Seller is a party or by which
            the Seller or, to the best of the Seller's knowledge the Properties
            are bound; (b) violate, conflict or constitute a breach of any
            statute, regulation or judicial or administrative order, award,
            judgment or decree to which the Seller is a party or to which the
            Seller or, to the best of the Seller's knowledge the Properties are
            bound; or (c) result in the creation or imposition of any adverse
            claim or interest, lien, encumbrance, charge, equity or restriction
            of any nature whatever, upon or affecting the Seller, or to the best
            of the Seller's knowledge, the Properties or the Purchaser.

     3.7    Litigation. Except as disclosed in Schedule "3.7" attached hereto as
            a part hereof, there is to the best of the Seller's knowledge and
            subject to the Seller's rights under the Amoco Agreement: (a) no
            action, suit or proceeding pending, threatened or contemplated
            against the Seller or the Properties; and (b) no proceeding,
            investigation, charges, audit or inquiry threatened or pending
            before or by any federal, state, municipal or other governmental
            court, department, commission, board, bureau, agency or
            instrumentality which might result in an adverse effect on the
            Seller or the Properties. The Seller hereby agrees to indemnify and
            hold harmless the Purchaser with respect to any and all litigation
            and proceedings including, without limitation, the matters described
            in Schedule "3.7."

     3.8    Title. Except as set forth in Schedule "3.8" attached hereto as a
            part hereof, the Seller owns, possesses and holds good and
            defensible title beneficially and of record in and to the respective
            Properties free and clear of all claims, liens, encumbrances,
            conditions, restrictions, calls on production, obligations to pay to
            or share with third parties any revenue or other matter adversely
            affecting the value or ownership of the Properties. All of the oil,
            gas and related interests of every kind and character owned by the
            Seller or any of the Seller's direct or indirect subsidiaries which
            are located in the Arkoma Basin are described in Schedule "1.1"
            hereto. The Seller is entitled to receive not less than the "Net
            Revenue Interest" set forth on Schedule "1.1" of all Hydrocarbons
            produced, saved and marketed from the Properties without reduction,
            suspension or termination of such interest throughout the duration
            of the productive life of such Properties and is in no event
            obligated to bear any of the costs and expenses related to the
            maintenance, development or operation (including, without
            limitation, the costs and expenses of plugging and abandoning any
            wells and removal and salvage of any equipment and facilities) of
            the Properties throughout the productive life of the Properties in
            excess of the "Working Interest" set forth in Schedule "1.1." To the
            best of the Seller's knowledge, Amoco has been receiving the
            percentage of the fair market value of all Hydrocarbons produced,
            saved or used from each of the Properties equal to the Net Revenue
            Interest designated on Schedule "1.1" for such Property.

                                      -5-
<PAGE>
 
            To the best of the Seller's knowledge, there are no suspended
            revenues or any basis to suspend revenues from the Properties. To
            the best of the Seller's knowledge, there does not exist any lien,
            claim, encumbrance, restriction or other matter which might cause
            the Purchaser to not receive for its own account free and clear of
            all liens, claims and encumbrances the percentage of the fair market
            value of all Hydrocarbons produced, saved or used from each of the
            Properties after the Effective Date equal to the Net Revenue

            of a material fact and does not omit to state a material fact
            necessary to make the statements made, in the circumstances under
            which they were made, not misleading. All of the representations,
            warranties and covenants in this Agreement: (a) are true and correct
            as of the date made; (b) will be true and correct as of the Closing
            Date; and (c) will survive and not be waived, discharged, released,
            modified, terminated or affected by any due diligence by the
            Purchaser.

4.   Purchaser's Representations and Warranties. The Purchaser is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Oklahoma and has all requisite corporate power and authority to own,
lease, and operate its properties and to conduct its business as now being
conducted. The Purchaser has full corporate power and authority to execute,
deliver and perform this Agreement.

5.   Covenants. The parties agree to perform the following prior to the Closing
Date:

     5.1    Access to Information. During the period commencing on the date of
            this Agreement and ending on the Closing Date, the Seller will
            afford the Purchaser and the Purchaser's authorized representatives
            full access during normal business hours to the properties, books,
            records, employees, accountants and lawyers of the Seller to make
            such investigation as the Purchaser desires regarding the Properties
            and furnish such financial, operating data, information and
            responses as the Purchaser might reasonably request with respect to
            the

                                      -9-
<PAGE>
 
            Properties.

     5.2    Inspection. Prior to the Closing Date the Purchaser will conduct
            such investigation and inspection with respect to the Properties as
            the Purchaser deems appropriate. If the Purchaser determines that by
            comparing the Reserve Report to more accurate title, net revenue and
            net working interests information, the amount of reserves
            attributable to the Properties is less than ninety-five percent
            (95%) of the amount set forth in the Reserve Report, the Purchase
            Price will be adjusted by an amount equal to the amount by which
            such discrepancies exceed five percent (5%) of the Purchase Price.

     5.3    Title Adjustments. In addition to any other remedies available to
            the Purchaser, if a casualty or title defect exists with respect to
            one (1) or more of the Properties which the Seller refuses to or
            cannot cure on or before August 1, 1998, then the Purchase Price
            will be adjusted downward as provided herein with such adjustment
            being accounted for in the post closing allocations under paragraph
            9 of this Agreement. If the casualty or title defect is an
            encumbrance or charge which is undisputed and liquidated the
            decrease in the Purchase Price will be the amount necessary to
            satisfy such charge and remove the title defect. In all other cases,
            the amount of the decrease in the Purchase Price will be the amount
            determined by multiplying (a) the percentage of the specific
            Property affected by the casualty or title defect by (b) the
            allocation of the Purchase Price to that specific Property. As used
            in this Agreement, "title defect" means: (a) the Seller's title at
            the Effective Date or at the Closing Date is subject to a mortgage,
            deed of trust, lien or security interest; (b) any of the interests
            in the Properties are subject to being reduced by virtue of the
            exercise by a third party of any preferential purchase rights,
            reversionary or back-in interest, farmout of other than wellbore
            rights or other similar rights; or (c) any claim, encumbrance,
            defect or other matter which: (i) would cause the Purchaser to
            receive (free and clear of all royalties, overriding royalties, net
            profits interests or other burdens on or measured by production of
            hydrocarbons and associated gases) less than one hundred percent
            (100%) of the "Net Revenue Interests" set forth in Schedule "1.1" of
            all oil, gas, sulfur and associated liquid and gaseous hydrocarbons
            and other associated gases produced, saved and marketed from the
            Properties for the productive life of such Properties; or (ii) would
            obligate the Purchaser to bear costs and expenses relating to the
            maintenance, development or operation of any of the Properties in an
            amount greater than the "Working Interests" set forth in Schedule
            "1.1" during the productive life of such Property.

     5.4    Conduct of Businesses. Prior to the Closing Date, the Seller will
            operate the Properties in a businesslike manner in accordance with
            the Seller's prior practices and will use the Seller's best efforts
            to maintain and preserve the Properties. In addition, unless the
            Purchaser otherwise consents in writing (a)

                                      -10-
<PAGE>
 
            the Seller has not and will not transfer, sell, mortgage, pledge,
            encumber or dispose of any of the Properties; or (b) make, permit
            any amendment or permit the termination of any material contract,
            agreement or commitment relating to the Properties. The Seller and
            the Seller's affiliates, advisors or representatives will not,
            directly or indirectly, encourage, initiate, engage in discussions
            or negotiations with, or provide any information to, any
            corporation, partnership, person or other entity or group concerning
            the sale of the Properties.

     5.5    Consents. The parties will use their best efforts to obtain all
            licenses, permits, consents, approvals, authorizations,
            qualifications and orders of governmental authorities and parties to
            contracts with the Seller as are necessary for the consummation of
            the transactions contemplated by this Agreement. However, no
            contract will be amended to increase the amount payable thereunder
            and no burden to the Seller or the Purchaser will be increased to
            obtain any consent, approval or authorization.

     5.6    Conditions. The Seller and the Purchaser will use their respective
            best efforts to cause the conditions in paragraphs 6 and 7 to be
            satisfied.

     5.7    Capital Expenditures. The Seller will not incur or make any
            commitment to incur any costs or expenses relating to the Properties
            in excess of Twenty-Five Thousand Dollars ($25,000.00) unless the
            Purchaser otherwise consents thereto in writing, which consent will
            not be unreasonably withheld.

            and operation of the Properties shall have been disclosed to the
            Purchaser and subject to adjustment under paragraph 5.3 of this

     11.3   Indemnification Procedure. If any party hereto discovers or
            otherwise becomes aware of an indemnification claim arising under
            this Agreement, such indemnified party will give written notice to
            the indemnifying party, specifying such claim, and may thereafter
            exercise any remedies available to such party under this Agreement;
            provided, however, that the failure of any indemnified party to give
            notice as provided herein will not relieve the indemnifying party of
            any obligations hereunder, to the extent the indemnifying party is
            not materially prejudiced thereby. Further, promptly after receipt
            by an indemnified party hereunder of written notice of the
            commencement of any action or proceeding with respect to which a
            claim for indemnification may be

                                      -16-
<PAGE>
 
            made against any indemnifying party, the indemnified party will give
            written notice to the latter of the commencement of such action;
            provided, however, that the failure of any indemnified party to give
            notice as provided herein will not relieve the indemnifying party of
            any obligations hereunder, to the extent the indemnifying party is
            not materially prejudiced thereby.

     11.4   Defense. If any such action is brought against an indemnified party,
            the indemnifying party will be entitled to participate in and to
            assume the defense thereof to the extent that it may wish, with
            counsel reasonably satisfactory to such indemnified party, and after
            such notice from the indemnifying party to such indemnified party of
            its election so to assume the defense thereof, the indemnifying
            party shall not be liable to such indemnified party for any legal or
            other expenses subsequently incurred by the latter in connection
            with the defense thereof unless the indemnifying party has failed to
            assume the defense of such claim and to employ counsel reasonably
            satisfactory to such indemnified person. Notwithstanding any of the
            foregoing to the contrary, the indemnified party will be entitled to
            select its own counsel and assume the defense of any action brought
            against it if the indemnifying party fails to select counsel
            reasonably satisfactory to the indemnified party, the expenses of
            such defense is to be paid by the indemnifying party. No
            indemnifying party shall consent to entry of any judgment or enter
            into any settlement with respect to a claim without the consent of
            the indemnified party, which consent shall not be unreasonably
            withheld, or unless such judgment or settlement includes as an
            unconditional term thereof the giving by the claimant or plaintiff
            to such indemnified party of a release from all liability with
            respect to such claim. No indemnified party shall consent to entry
            of any judgment or enter into any settlement of any such action, the
            defense of which has been assumed by an indemnifying party, without
            the consent of such indemnifying party, which consent shall not be
            unreasonably withheld.

     11.5   Interest. In addition to the foregoing, the indemnifying party will
            pay to the indemnified party interest on the amount of any loss,
            damage, claim, liability, debt, obligation or expense the payment of
            which is not paid within ten (10) days after notification by the
            indemnified party by the indemnifying party, such interest to be at
            a floating rate of interest equal to the prime rate published from
            time to time in The Wall Street Journal. The remedies provided by
            this paragraph 11 are in addition to, and not in lieu of, such other
            remedies as may be available under applicable laws. Claims for
            indemnification will be paid by the indemnifying party within ten
            (10) days after notification thereof.

12.  Termination. This Agreement may be terminated and the transactions
contemplated hereby may be abandoned by: (a) mutual consent of the Seller and
the Purchaser; (b) the Purchaser, if the Purchaser is not in default and the
conditions set forth in paragraph 6 of this Agreement have not been satisfied by
the Seller or waived by the Purchaser; or (c) the Seller, if

                                      -17-
<PAGE>
 
the Seller is not in default, and the conditions precedent set forth in
paragraph 7 of this Agreement have not been satisfied or waived by the Seller.
In the event of termination, written notice thereof will be given to the other
party or parties specifying the provision pursuant to which such termination is
made. On termination pursuant to this paragraph 12, this Agreement will become
void and have no effect, and there will be no liability hereunder on the part of
the Purchaser or the Seller or any of their respective officers, directors,
employees, agents, stockholders or principals.

13.  Default. If a party fails to perform any obligation contained in this
Agreement, the party claiming default will serve written notice to the other
party specifying the nature of such default and demanding performance. If the
Seller fails to cure such default within ten (10) days after receipt thereof,
the Purchaser will have the option to waive such default, to demand specific
performance, to exercise any other remedy available at law or in equity or to
terminate this Agreement. If the Purchaser fails to cure such default within ten
(10) days after receipt thereof, the Seller will have the option to waive such
default, terminate this Agreement or exercise any other remedy available at law
or in equity. The Purchaser is entitled to enforce this Agreement by specific
performance without the necessity of demonstrating inadequacy of damages or
irreparable harm.

14.  Miscellaneous.  It is further agreed as follows:

     14.1   Time.  Time is of the essence of this Agreement.

            to be given by any provision of this Agreement will be in writing

            personally or by telefacsimile to the party designated to receive
