ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS:

     On February 18, 1997, the Company acquired from Norse Exploration, Inc.,
and Norse Pipeline, Inc. (collectively, "Norse"), various working interests in
11 oil and gas producing properties and, through the acquisition of the
outstanding capital stock of Norse Pipeline, Inc., its 40.09% general
partnership interest in the Sycamore Gas System (the "Sycamore System"), an
Oklahoma gathering system, processing plant and storage facility. The oil and
gas wells and the gathering system are located in the Springer Field in Carter
County, Oklahoma. The total purchase price was $10,750,000, plus two-year
warrants to purchase 200,000 shares of the Company's Common Stock at a per share
exercise price of $2.50. The estimated fair value of such warrants at the date
of acquisition was approximately $254,000. The Company paid a deposit of
$1,075,000 toward the purchase price in December 1996.

     The Company also on February 18, 1997, acquired from H. Huffman & Company
("Huffman"), an Oklahoma limited partnership, various working interests in 13
oil and gas producing properties and an additional 10.97% interest in the
Sycamore System.  The oil and gas wells are located in the same producing area
as the properties acquired from Norse.  The total purchase price for the assets
acquired was $3,950,000, of which the Company paid a deposit of $287,500
toward the purchase price in December 1996.

     The Company also acquired, on February 18, 1997, from Horizon Gas Partners,
L.P. and HSRTW, Inc. (collectively, "Horizon"), various working and royalty
interests in approximately 100 oil and gas producing properties.  The producing
properties are located in Major and Blaine counties of Oklahoma.  The purchase
price was $10,000,000.

     The effective date of all three acquisitions was January 1, 1997.

     Financing for the acquisition was provided primarily by bank borrowing.  On
February 17, 1997, the Company and Bank One, Texas, N.A., entered into a
Restated Loan Agreement (the "Credit Facility") which currently enables the
Company to borrow, from time to time and, subject to meeting certain borrowing
base requirements and other conditions, a maximum aggregate of $75,000,000 as of
February 17, 1997.  The current maximum aggregate available to be borrowed under
the Credit Facility is $44,000,000 and is comprised of a $32,000,000 borrowing
availability (the "borrowing base") based on the Company's oil and gas reserve
reports, a $10,000,000 special advance facility (the "Special Advance Facility")
and a $2,000,000 special drilling facility.  On February 18, 1997, the Company
drew down both the borrowing base and the Special Advance Facility for a total
of $41,668,000. These funds were used to repay all existing indebtedness then
outstanding owing to the bank in the amount of $21,264,000, to finance the cash
consideration paid for the three February 18, 1997 acquisitions discussed above
which aggregated $19,404,000, and to pay a $1,000,000 loan fee to Bank One.  An
aggregate of $1,291,295 of the previously paid deposits against the purchase
price for the Norse and
                                       2
<PAGE>
 
Huffman acquisitions had been borrowed from the bank in December 1996 against
the Company's borrowing availability at the time.

     The remaining funds necessary to complete the acquisitions were provided by
loans to the Company from two investors.  On February 18, 1997, such persons
loaned to the Company the aggregate sum of $4,500,000 represented by the
Company's promissory notes.  Of the aggregate amount, $2,500,000 bears interest
at 5% per annum and matures on April 18, 1997, with the remaining $2,000,000
bearing interest at 12% per annum and maturing on October 31, 1997.  In the
event the principal and accrued interest is not paid when due, such amount is
automatically converted into a number of shares of the  Company's Common Stock
determined by dividing such amount by a sum equal to 75% of the closing bid
price for the Company's Common Stock on the five (5) days prior to the maturity
date, with respect to the $2,500,000 obligation, and on the maturity date with
respect to the $2,000,000 obligation.  As additional consideration for making
the loan, the investors also purchased at a price of $.01 per share a total of
250,000 shares of the Company's common stock. The fair value of the Company's 
common stock was $2.63 per share on the date such shares were issued.

     3.2  TITLE DEFECTS; DEFENSIBLE TITLE.
          ------------------------------- 

          (a)  Adjustments to the Base Price for failure of title may be made
     with respect to the Properties and the Sycamore System (insofar as any
     title failure affects the value of Seller's interest in Sycamore).  The
     Properties and the Sycamore System are hereinafter referred to collectively
     as the "Examined Interests".  As used herein, the term "Title Defect" shall
     mean any lien, claim, defect, encumbrance, security interest, burden of
     deficiency such that (i) Seller does not have Defensible Title (hereinafter
     defined), as distinguished from technically marketable title, to any of the
     Properties, or (ii) to the extent of Seller's interest in Sycamore,
     Sycamore does not have Defensible Title to the assets and properties
     comprising the Sycamore System; provided, no Permitted Encumbrances
     (hereinafter defined) shall constitute a Title Defect.

          (b)  As used herein, the term "Defensible Title" (i) with respect to
     the Sycamore System means clear, unencumbered and uncontested title in
     Sycamore to the real and personal property comprising the Sycamore System,
     and (ii) with respect to the 

                                       3
<PAGE>
 
     Properties means clear, unencumbered and uncontested title in Seller to the
     Properties such that (A) after giving effect to existing spacing orders,
     operating agreements, unit agreements, unitization orders and pooling
     designations, and subject to the limitations, if any, described in Exhibit
     A, and after taking into account all royalty interests, overriding royalty
     interests, net profit interests, production payments and other burdens on
     production, Seller is entitled to a share (expressed as a decimal) of all
     oil, gas and other minerals produced from each well described in Exhibit A
     which is not less than the Net Revenue Interest set out in Exhibit A in
     connection with the description of such well, (B) Seller owns an undivided
     interest (expressed as a decimal) equal to the Working Interest set out in
     Exhibit A in connection with the description of each such well in and to
     all property and rights incident thereto, including all rights in, to and
     under all agreements, leases, permits, easements, licenses and orders in
     any way relating thereto, and in and to all wells, personal property,
     fixtures and improvements thereon, appurtenant thereto or used or obtained
     in connection therewith or with the production or treatment or sale or
     disposal of hydrocarbons or water produced therefrom or attributable
     thereto, (C) Seller is obligated for a fraction of the costs relating to
     the exploration, development and operation of such well no greater than the
     Working Interest set out in Exhibit A in connection with the description of
     such well, and (D) except as shown in Exhibit A, Seller's interests in such
     wells and the production therefrom are not subject to being reduced by
     virtue or reversionary interests owned by third parties.

          (c)  As used herein, the term "Permitted Encumbrances" means (i)
     matters described without material omission in any of the Exhibits or
     Schedules attached hereto, (ii) royalties, overriding royalties, net
     profits interests, production payments and other burdens on production
     which do not reduce Seller's Net Revenue Interest in any of the Properties
     to less than that described in Exhibit A, (iii) mortgage liens to be
     discharged at Closing, liens for taxes, assessments, labor and materials
     where payment is not due, (iv) operating agreements, unit agreements,
     farmout agreements, letter agreements, easements, rights-of-way,
     unitization and pooling designations and declarations, gathering and
     transportation agreements, processing agreements, gas, similar agreements
     which are not required by the terms of this Agreement to be disclosed on
     any Schedule hereto, provided (A) all amounts due and payable by Seller
     thereunder have been paid, and (B) Seller is not in default thereunder, (v)
     regulatory authority of governmental agencies not presently or previously
     violated, easements, surface leases and rights, plat restrictions and
     similar encumbrances, provided that they do not detract from the value, and
     can increase the cost of operation of any of the Properties or the Sycamore
     System or otherwise adversely affect the operation thereof, and (vi) liens,
     charges, encumbrances and irregularities in the chain of title which,
     because of statutory cure periods or marketable title acts have and cannot
     affect adversely or interrupt, the claimed ownership of Seller or its
     predecessors in or the receipt of production revenues from the Properties
     affected thereby.

     3.3  TITLE EXAMINATION; NOTICE OF DEFECTS.
          -------------------------------------

          (a)  Promptly after execution of this Agreement, Buyer shall, at
     Buyer's sole cost and expense, commence and pursue such examination of
     title to the Examined Interests as Buyer deems necessary or proper.  Buyer
     will conclude its title review and give notice to Sellers of any asserted
     Title Defects affecting the Examined Interests not later than fifteen (15)
     days prior to the date scheduled for the Closing in Section 12.1 hereof
     (the "Title Notice Date").  Each such notice shall include a brief
     description of each Title Defect of which notice is being given, the action
     required to cure such Title Defect and the proposed adjustment to the Base
     Price by reason of the existence of such Title Defect.  Buyer shall be
     deemed to have waived any Title Defects existing with respect to the
     Examined Interests except to the extent such Title Defects are set out in a
     notice given on or prior to the Title Notice Date.

          (b)  Seller shall have a period of twelve (12) days after the Title
     Notice Date to cure all or any portion of the Title Defects described in
     any notice(s) of Title Defects affecting Examined Interests properly given
     by Buyer prior to such date.  In the event Seller is unable or unwilling to
     cure any of the asserted Title Defects prior to the expiration of each cure
     period, and exceed ten percent (10%) of the interests set out in Exhibit A,
     Seller shall have the right to terminate this Agreement, or if Seller
     elects not to terminate, the parties shall proceed in accordance with
     Section 3.4.

     3.4  ADJUSTMENTS.
          ----------- 

          (a)  If any uncured Title Defect is based on Buyer's substantiated
     notice in reasonable detail that Seller owns a Net Revenue Interest less
     than that shown on Exhibit A with respect to a particular Property, then
     the Agreed Value of such Property shall be reduced in the same proportion
     that the actual Net Revenue Interest bears to the Net Revenue Interest
     shown therefor on Exhibit A and the amount of such reduction shall
     constitute the approved adjustment amount with respect to such Title
     Defect, and as a result of such reduction, Seller shall only be obligated
     to convey the exact amount of the interest computed based on the actual Net
     Revenue Interest and Seller shall retain all amounts in excess thereof.

          (b)  If any uncured Title Defect involves a substantiated claim
     against or uncertainty with respect to Seller's title to a particular
     Property or Sycamore's title to the Sycamore System, the parties shall
     attempt to negotiate a mutually acceptable reduction in the Agreed Value of
     the affected item of the Interests by reason of such defect. In the event
     the parties agree on an appropriate reduction in the Agreed Value, such
     amount shall constitute the principal amount of Buyer's approved claim with
     respect to such Title Defect. If the parties are unable to agree on an
     appropriate reduction and Buyer elects not to waive the Title Defect, then
     Seller shall have the option of (i) proceeding to Closing but reducing the
     Base Price by the Agreed Value of such item, or (ii) excluding the

                                       5

default under, any contract or agreement affecting the Interests or constitute
the happening of a condition upon which any other party to such a contract may
exercise any right or option which will adversely affect any of the Interests.

          --------------------                                               
otherwise, for brokers' or finders' fees in respect of this transaction for

                      COVENANTS OF SELLER PENDING CLOSING
                      -----------------------------------

     Seller covenants and agrees with Buyer that from and after the date of this
Agreement and until the Closing, Seller will conduct its business, and will use
its best efforts to cause Sycamore to conduct its business, subject to the
following provisions and limitations:

     6.1  ORDINARY COURSE.  To the extent the Seller has the right, the
          ---------------                                              
Properties and the Sycamore System will be maintained and operated in a good and
workmanlike manner consistent with historical practices, and Seller will timely
pay or cause to be paid all costs and expenses incurred in connection therewith.

     6.2  RESTRICTIONS ON OPERATIONS. Subject to the provisions of Section 7.5
          ---------------------------                                         
hereof, except with Buyer's prior written consent no operations will be
conducted for the drilling of any new well, the reworking or redrilling of any
existing well or the making of any other capital expenditure on the Properties
or the Sycamore System requiring an expenditure by Seller.  Insofar as any of
the following described actions would affect the Interests, neither Seller nor
Sycamore will waive any rights or enter into any new agreements or commitments
other than in the ordinary course of business, abandon any well capable of
commercial production (based upon prevailing economic conditions), release or
abandon any Properties, or encumber, sell or otherwise dispose of any of the
Properties other than personal property thereon which is replaced by equivalent
property or consumed in the operation of such Properties in the ordinary course
of business.

     6.3  MAINTENANCE OF FILES.  Seller will exercise reasonable diligence in
          ---------------------                                              
safeguarding and maintaining secure all files, books and records currently
maintained.

     6.4  ACCESS OF BUYER.  Buyer shall have access to the employees, offices,
          ---------------                                                     
properties, records, files, geological and geophysical data, engineering reports
and evaluations, books of account, and all other information of the Seller
pertaining to the Interests; provided, however, that such investigation shall be
conducted during normal business hours and in a manner that does not
unreasonably interfere with Seller's normal operations.  During such
investigation, Buyer shall have the right, at Buyer's sole cost and expense, to
make copies of such records, files and other materials as Buyer may deem
advisable.

                                   ARTICLE 7

                     ADDITIONAL AGREEMENTS OF THE PARTIES
                     ------------------------------------

     7.1  RETURN OF INFORMATIONAL MATERIAL.  If this Agreement is not
          --------------------------------                           
consummated, Buyer shall return to Seller all of the items of information which
Seller has delivered to Buyer hereunder, including all copies of same made by
Buyer.

     7.2  CONFIDENTIALITY OF INFORMATION. If the purchase and sale of the
          -------------------------------                                
Interests as contemplated by this Agreement is not completed, Buyer (i) will
keep the information furnished to Buyer hereunder or in contemplation hereof
strictly confidential, except to the extent such information (a) becomes public
other than as a result of dissemination by Buyer, (b) was already known to Buyer
other than as a result of a breach of a confidentiality restriction, or (c) is
furnished to Buyer by a third party independently of Buyer's investigation
pursuant to this Agreement, and (ii) will not use any of such information to
Buyer's fumcial advantage or in competition with Seller or Sycamore.
Notwithstanding the provisions of Section 14.6 hereof, this provision shall not
be construed as superseding or limiting the provisions of any confidentiality
agreement heretofore executed by and between Buyer and Seller.

     7.3  COMPLIANCE WITH CONDITIONS. Buyer and Seller, respectively, will
          ---------------------------                                     
proceed diligently using all reasonable efforts to cause all of the conditions
to the obligations of Seller and Buyer, respectively, to be timely satisfied.

     7.4  GAS IMBALANCES.  Seller and Buyer acknowledge, but Seller does not
          ---------------                                                   
represent or warrant, that certain gas imbalances existed at the Effective Time
with respect to production from or attributable to certain of the Properties.
The best information concerning such imbalances available to Seller as of the
date of this Agreement is set forth on Schedule 7.4 and such imbalances have
been taken into account by Buyer in determining the Purchase Price.  If, prior
to the Title Notice Date, Buyer determines that the net gas imbalance (that is,
the difference between aggregate overproduction attributable to Seller's
interest in the Properties and the aggregate underproduction attributable to
such interest) at the Effective Time was different than that set forth on
Schedule 7.4, Buyer shall so notify Seller.  If such difference is confirmed,
the Base Price shall be adjusted at the Closing by an amount equal to $1.00 per
Mcf for the difference from that shown in Schedule 7.4; provided, however, that
no adjustment shall be made unless the difference exceeds 20,000 Mcf.

     7.5  CAPITAL EXPENDITURES. During the period from the execution of this
          ---------------------                                             
Agreement to the Closing Date, Seller will consult with Buyer from time to time
with respect to any operation proposed to be conducted on the Properties or the
Sycamore System and reasonably expected to require an expenditure by Seller for
any single project, and will provide Buyer with all information reasonably
available to Seller with respect thereto.  Buyer shall, within ten (10) days
after receipt of Seller's recommendation for conducting or participating in any
such project, or within such lesser period as may be required by the terms of
any applicable agreement, 

                                       11
<PAGE>
 
approve or disapprove such project. Failure of Buyer to respond within the time
required will be deemed to constitute disapproval by Buyer of the project. In
the event Buyer approves such project, Seller shall conduct, propose or elect to
participate in such project and shall incur and pay as they become due the
expenditures associated therewith. In the event the project or operation is a
well proposed by an unrelated third party and Seller must, by operation of an
applicable agreement or order of a regulatory agency, elect either to
participate in such well or lose the right to participate in such well and/or
other rights in the unit in which such well is proposed (for example, but not by
way of limitation, a non-consent penalty under a joint operating agreement,
requirement to accept consideration in lieu of participation under a pooling or
forfeiture of the right to participate in future development under an area of
mutual interest agreement), and Buyer disapproves or is deemed to have
disapproved participation by Seller in such well, then, five (5) days written
notice to Buyer (during which time Buyer may reverse its decision and approve
participation by Seller), Seller, at its sole option, may elect to exclude from
the Interests and the sale hereunder the Property on which such operation is to
be conducted and reduce the Base Price by the Agreed Value of such Property, or
terminate this Agreement without further obligation to Buyer.

     7.6  CONSENTS; PREFERENTIAL RIGHTS TO PURCHASE. Promptly after execution
          ------------------------------------------                         
hereof, Seller will proceed diligently to solicit any consents to the transfers
contemplated hereby which are required to be obtained from third parties and
will give all notices required by existing contracts with respect to
preferential rights to purchase on the part of third parties and to obtain
waivers of such preferential rights.  Any item of the Interests which requires
the consent of a third party for transfer where such consent cannot be obtained
prior to the Closing Date (other than routine consents required in connection
with federal, state and Indian leases), or which is subject to a preferential
right to purchase which has not expired and has been waived prior to the Closing
Date, may, at Buyer's option, be excluded from the Interests and the sale
hereunder and the Base Price reduced by the Agreed Value of such Property.

     7.7  ADJUSTMENTS FOR OPERATIONS SUBSEQUENT TO THE EFFECTIVE TIME.  The
          ------------------------------------------------------------     
following adjustments shall be made to the Base Price for operations conducted
subsequent to the Effective Time to the extent the following described items of
revenue and expense relate to the Interests:

          (a)  The Base Price shall be adjusted upward by all amounts actually
     paid by Seller in respect of (i) actual direct operating expenses and
     capital expenditures (other than those prohibited by the terms hereof),
     (ii) overhead or indirect expenses required to be paid by the terms of
     existing operating agreements, and (iii) ad valorem, property, production,
     severance and similar taxes and assessments based upon or measured by the
     ownership of property, the production of removal of hydrocarbons or the
     receipt of proceeds therefrom; to the extent such expenditures relate to
     the period between the Effective Time and the Closing Date on the accrual
     method of accounting.  Ad valorem taxes shall be prorated on the basis of
     time, and if the taxes cannot be determined for the current taxable year,
     then the amount thereof for the taxable year most recently ended shall be
     used in determining ad valorem taxes attributable to a particular period of
     time.

                                       12
<PAGE>
 
          (b)  The Base Price shall be adjusted downward by all proceeds
     actually received by Seller (including proceeds from sale or salvage of any
     personal property forming a part of the Interests as well as the
     hydrocarbons produced therefrom and attributable thereto) to the extent
     such proceeds relate to the period from the Effective Time to the Closing
     Date on the accrual method of accounting. Proceeds received by Seller after
     the Effective Time for the sale of production in storage at the Effective
     Time shall remain the property of Seller and shall not give rise to an
     adjustment.

                             ENVIRONMENTAL MATTERS
                             ---------------------

     8.1  PHYSICAL CONDITION OF THE PROPERTIES.  The Properties (solely for
          ------------------------------------                             
purposes of this Article, the term "Properties" shall include the Sycamore
System) have been used for oil and gas drilling, production, gathering and
processing operations, and related oil field operations.  Physical changes in or
under the Properties or adjacent lands may have occurred as a result of such
uses.  The Properties also may contain buried pipelines and other equipment,
whether or not of a similar nature, the locations of which may not be known to
Seller or be readily apparent by a physical inspection of the Properties.  Third
parties may have used the Properties or the surface rights thereon for other
purposes as well.  Buyer understands that Seller does not have the requisite
information with which to determine the exact nature or condition of the
Properties nor the effect any such use has had on the physical condition of the
Properties.  Buyer is hereby notified that detectable amounts of regulated and
unregulated chemicals and other substances which may pose a threat to health or
to plants or wildlife, or which are known to cause illnesses, diseases, cancer,
birth defects and other reproductive harm, may be found in, on or around the
Properties.  Adverse physical conditions, including the presence of such
chemicals and other substances, may not be revealed by Buyer's investigation.
In addition, Buyer acknowledges that some oil field production equipment may
contain various contaminants or hazardous substances, including without
limitation, asbestos and/or naturally-occurring radioactive material ("NORM").
In this regard, Buyer expressly understands that NORM may affix or attach itself
to the inside of wells, materials, pipes and equipment as scale or in other
forms, and that wells, materials, pipes and equipment located on the Properties
may contain NORM and that NORM-containing materials may be buried or have been
otherwise disposed of on the Properties.  Buyer also expressly understands that
special procedures may be required for the removal and disposal of various
contaminants or hazardous substances, including without limitation, asbestos and
NORM, from the Properties where it may be found.  The statements in this Section
8.1 are intended as disclosures and acknowledgments of possible conditions
existing on the Properties.  Seller hereby advises that it has not been notified
of any noncompliance up to the date of closing.

     8.2  ENVIRONMENTAL ASSESSMENT. Buyer shall have the right, at Buyer's sole
          -------------------------                                            
cost, risk, and expense, to undertake an environmental assessment of the
Properties during the period ending on the Title Notice Date (the "Inspection
Period").  Buyer and its agents shall have the 

                                       13
<PAGE>
 
same right as Seller to enter upon the Properties, inspect the same, conduct
soil and water sampling, analysis and monitoring, including soil borings (and,
after notice and consultation with Seller, drilling groundwater monitoring
wells), and generally conduct such tests, examinations, investigations and
studies as Buyer deems necessary or appropriate for preparing appropriate
engineering and other reports and making judgments relating to the Properties,
their condition, and the presence of chemicals and other substances. Seller
shall cooperate with any efforts of Buyer and its agents to obtain third party
consents for access to those parcels of land within the Properties to which
Seller may not presently have access. Buyer and its agents shall have reasonable
access to Seller's agents and employees in the course of conducting Buyer's
environmental assessment. Buyer agrees to provide to Seller a copy of all facts
discovered in the course of conducting Buyer's environmental assessment,
including all direct observations (if in writing or other tangible or
transferable medium), data and summaries thereof. Buyer shall keep any data or
information acquired in the course of such examinations and the results of all
analyses of such data and information strictly confidential and not disclose
same to any person or agency without the prior written approval of Seller,
except that Buyer may disclose to authorities having jurisdiction such
information as is required by law or by court order at the same time that Buyer
provides such information to Seller. If Buyer determines that conditions on a
Property do not satisfy the environmental standards set forth in Section 8.4
below in a material respect, then Buyer may notify Seller of such condition by
providing Seller, on or prior to the Title Notice Date, a written "Notice of
Environmental Defect" setting forth in detail the facts giving rise to the
claimed defect, the environmental standard which Buyer claims is not satisfied,
any Applicable Environmental Law (hereinafter defined) which Buyer contends has
been breached or violated and, if the claimed defect arises from information
contained in a document, a copy of such document or the relevant parts thereof.
Buyer shall be deemed to have accepted without objection (i) the environmental
conditions described in Schedule 8.4, and (ii) any Property which does not meet
the environmental standards or which is subject to an environmental defect
unless a Notice of Environmental Defect is given with respect to such Property
on or prior to the First Title Notice Date.

     8.3  ACCESS; INDEMNIFICATION.  Access to the Properties to conduct Buyer's
          ------------------------                                             
environmental assessment shall be subject to the following conditions: Buyer
waives and releases all claims against Seller and its successors, assigns,
directors, officers, contractors, affiliates, partners, employees and agents,
for injury to or death of persons or damage to property arising in any way from
the exercise of rights granted to Buyer hereby or the activities of Buyer or its
employees, agents or contractors on the Properties, provided that Buyer does not
hereby assume the risk of damage, injury or death attributable to the willful
misconduct or gross negligence of Seller.  Buyer shall indemnify Seller, its
partners, employees, and agents, and shall hold each and all of said indemnities
harmless from and against any and all loss whatsoever arising out of (i) any and
all statutory or common-law liens or other encumbrances for labor or materials
furnished in connection with such tests, samplings, studies or surveys as Buyer
may conduct with respect to the Properties, and (ii) any injury to or death of
persons or damage to property occurring in, on or about the Properties as a
result of such exercise or activities (except for any such injuries or damages
caused by the gross negligence or willful misconduct of any 

                                       14

said indemnities). Notwithstanding any provision of this Agreement to the
contrary, the foregoing obligation of indemnity shall survive the Closing or the
termination of this Agreement without Closing.

     8.4  ENVIRONMENTAL STANDARDS.  This section sets out the environmental
          ------------------------                                         
standards applicable to the Properties for purposes of this Agreement and do not
constitute covenants, representations or warranties of Seller.  Seller disclaims
all warranties and representations regarding and makes no covenants with respect
to environmental conditions on the Properties.

          (a)  The Properties shall not have been used for the generation,
     treatment, storage or disposal of a Hazardous Substance (as defined below)
     in a manner or to an extent that would subject Seller to a material
     liability for violation of any Applicable Environmental Laws (as defined
     below).  Except as disclosed in Schedule 8.4, there shall not have been any
     release or discharge of a Hazardous Substance from the Properties in a
     manner or to an extent that would subject Seller to a material liability
     for violation of any Applicable Environmental Laws.  "Hazardous Substance"
     shall mean any hazardous substance, pollutant, contaminant, solid or
     hazardous waste, hazardous waste constituents, hazardous material or toxic
     substance subject to regulation or liability under Applicable Environmental
     Laws in force as of the date hereof, including asbestos, radioactive
     substances, and any other substance or material that would constitute or
     cause a health, safety or environmental hazard on or at the Properties
     under Applicable Environmental Laws.  "Applicable Environmental Laws" shall
     mean (i) all federal statutes regulating or prescribing restrictions
     regarding the use of the Properties or other activities affecting the
     environmental (air, water, land, animal and plant life), including but not
     limited to the following: the Clean Air Act, Clean Water Act, Comprehensive
     Environmental Response, Compensation and Liability Act, Emergency Planning
     and Community Right-to-Know Act, Endangered Species Act, Hazardous
     Materials Transportation Act, Migratory Bird Treaty Act, National
     Environmental Policy Act, Occupational Safety and Health Act, Oil Pollution
     Act of 1990, Resource Conservation and Recovery Act, Safe Drinking Water
     Act, and Toxic Substances Control Act; (ii) any regulations promulgated
     under such federal statutes; (iii) any state law counterparts of such
     federal statutes and the regulations promulgated thereunder; (iv) any other
     state or local statutes, rules regulations or ordinances regulating the use
     of or affecting the environmental; and (v) all common law rights, duties
     and obligations regarding the use of or matters affecting the environment.

          (b)  Except as disclosed in Schedule 8.4, there are no agreements,
     consent or administrative orders, injunctions, decrees, judgments, license
     or permit conditions, or other directives of governmental authorities based
     on any Applicable Environmental Laws that require any material change in
     the present condition of the Properties, and Seller has not received any
     notice from any government authority or private or public entity advising
     Seller that it is or is potentially responsible for response costs under an

                                       15
<PAGE>
 
     Applicable Environmental Law as a result of Seller's ownership or
     activities in connection with the Properties.

          (c)  Except as disclosed in Schedule 8.4, no conditions or
     circumstances exist on the Properties that would subject Seller to any
     material damages, penalties, injunctive relief or clean-up or closure costs
     under any Applicable Environmental Laws or that would require clean-up,
     removal, remedial or corrective action or other response involving a
     material expenditure by Seller pursuant to Applicable Environmental Laws.

     8.5  PROPERTIES SUBJECT TO ENVIRONMENTAL DEFECT.  Seller shall have a
          -------------------------------------------                     
period of twelve (12) days after the title Notice Date to cure or remediate the
environmental defect(s) set out in any Notice of Environmental Defect timely and
properly given by Buyer. In the event Seller is unable or unwilling to cure or
remediate any such defect prior to Closing, one of the following shall occur:

          (a)  The parties shall agree upon an adjustment to the Purchase Price
     to compensate Buyer (i) for the defect and all future liability associated
     therewith or resulting therefrom, and (ii) for agreeing to indemnify,
     defend and hold harmless Seller from and against any and all loss, cost,
     liability or expense associated therewith or resulting therefrom.

          (b)  Deleted.

          (c)  Notwithstanding the provisions of (a) above, Purchaser shall not
     be entitled to an adjustment of the Base Price pursuant to the provisions
     of this Section 8.5 unless the amount of the adjustment for each occurrence
     exceeds $25,000 to the interest of Seller.  Buyer shall be responsible for
     all adjustments up to $25,000, and Seller shall be responsible for amounts
     in excess of $25,000.  In the event there is an adjustment in excess of
     $50,000 to the interest of Seller for each occurrence, then in such event,
     Seller at its sole election can remove such property from the transaction,
     close and agree to adjust the purchase price.

     8.6  INDEMNIFICATION OF SELLER.  All liabilities attributable to conditions
          --------------------------                                            
existing and operations conducted on the Properties assigned to Buyer, under
Applicable Environmental Laws and under all future environmental laws, shall be
liabilities of Buyer, and Buyer shall indemnify, defend, and hold harmless
Sellers from and against all loss, cost, liability or expense attributable
thereto or resulting therefrom.

     8.7  MATERIALITY DEFINED. For purposes of this Article VIII, material and
          --------------------

to the interests of Seller per occurrence.

in the absence of satisfaction or affirmative waiver of any of the foregoing
conditions, Buyer shall be deemed to have waived its right not to close by
reason thereof.


                                  ARTICLE 10

                      CONDITIONS TO OBLIGATIONS OF SELLER
                      -----------------------------------

     The obligations of Seller to consummate the transactions provided for in
this Agreement shall be subject to the satisfaction of each of the following
conditions on or before the Closing Date, subject to the right of Seller to
waive any one or more of such conditions:

     10.1 REPRESENTATIONS AND WARRANTIES OF BUYER. The representations and
          ---------------------------------------                        
warranties of Buyer contained in Article 5 hereof shall be true and correct in

conditions, Seller shall be deemed to have waived its right not to close by

                                  TERMINATION
                                  -----------

     11.1 NONCOMPLIANCE BY SELLER.  Buyer may terminate this Agreement by
          -----------------------                                        
written notice to Seller if the conditions to Buyer's obligations under this
Agreement, as set forth in Article 9 hereof, shall not have been complied with
or performed in all material respects (and Seller shall not be prepared to
comply with or perform the same) by the date on which the Closing is to occur
(as set forth in Section 12. 1), and such non-compliance or non-performance
shall not have been waived in writing by Buyer.  Under such circumstances, Buyer
shall be entitled to a return of the Deposit, which shall be Buyer's sole remedy
hereunder unless such termination is a result or Seller's failure or refusal to
close the transaction contemplated hereby under circumstances in which all
conditions precedent to Seller's obligations as set forth in Article 10 have
been performed or satisfied in all respects, in which event Buyer shall be
entitled to pursue any remedies existing at law or in equity.

     11.2 NONCOMPLIANCE BY BUYER.  Seller may terminate this Agreement by
          -----------------------                                        
written notice to Buyer if the conditions to Seller's obligations under this
Agreement, as set forth in Article 10 hereof, shall not have been complied with
or performed in all material respects (and Buyer shall not be prepared to comply
with or perform the same) by the date on which the Closing is to occur (as set
forth in Section 12. 1), and such non-compliance or non-performance shall not
have been waived in writing by Seller.  In such event, Seller shall retain the
Deposit as liquidated damages for Buyer's failure to purchase the Interests at
the time specified herein.  The parties hereto agree that time is of the essence
for the consummation of the transactions contemplated hereby, that the amount of
damages caused by Buyer's breach would be very difficult to calculate exactly,
and that the provision for liquidated damages contained in this Section 11.2
shall not be construed as a penalty provision.  Such right to liquidated damages
shall be Seller's sole remedy hereunder.

     11.3 COOPERATION BY BUYER. In the event of termination of this Agreement,
          ---------------------                                               
Seller shall be free to sell the Interests to any third party without any
limitation under or by reason of this Agreement.  Buyer shall cooperate with
Seller in effectuating any such sale by promptly executing any instrument
reasonable requested by Seller evidencing the termination of this Agreement or
Buyer's right to acquire the Interests.

     11.4 ARBITRATION.  Unless otherwise specified in this Agreement, any
          ------------                                                   
controversy arising under this Agreement which the parties are unable to resolve
by mutual agreement, shall be submitted to binding arbitration in Dallas, Texas
in accordance with the then current rules of The Judicial Arbitration &
Mediation Services, Inc. (hereinafter referred to as the "JAMS").  Either party
may give to the other written notice of its desire to have a matter arbitrated,
in which event a hearing thereon shall commence within a reasonable time (not to
exceed fifteen (15) days thereafter.  Any decision of the arbitrators shall be
conclusive as to the matters submitted to them, shall be final and binding upon
the parties hereto, and may be enforced in any court of 

                                       18
<PAGE>
 
competent jurisdiction. Notwithstanding anything herein to the contrary, the
parties agree that any decision or award resulting from arbitration which
exceeds the sum of $ 1,000,000 shall be subject to appeal and judicial review
upon petition of either party.

February 15, 1997 (the date on which the Closing actually occurs is referred to
herein as the "Closing Date").  The Closing shall take place in the offices of
the Seller, 2500 Tanglewilde, Suite 250, Houston, Texas 77063, or such other

fully executed and acknowledged Assignment, Conveyance and Bill of Sale, in the
form attached hereto as Exhibit F, assigning to Buyer Seller's interest in the
Properties, and (ii) a fully executed and acknowledged Assignment of General
Partnership Interest, in the form attached hereto as Exhibit G, assigning to
Buyer Seller's general partnership interest in Sycamore.

     12.4 DETERMINATION AND PAYMENT OF PURCHASE PRICE.  On the day that is two
          -------------------------------------------

summary of the Base Price adjustments to be effected at the Closing pursuant to
Section 3.4, 7.4, 7.5, 7.6, 7.7 and 8.5 hereof, and subject to the provisions of
Section 3.7, and (ii) based upon the information at (i), a calculation of the
Purchase Price.  Buyer and Seller shall work together diligently and in good
faith prior to the Closing in an effort to agree upon the amount of the
adjustments necessary to determine the Purchase Price, and if they do so agree,
the agreed amount shall be paid by Buyer to Seller by wire transfer of
immediately available funds at the Closing (less any amount deposited in escrow
by Buyer pursuant to Section 3.5) If the parties cannot agree on the adjustment
amounts necessary to determine the Purchase Price, the Closing shall occur as
scheduled based on Seller's reasonable, good faith estimate of the Purchase
Price ("Seller's Estimate") and the difference between Seller's Estimate and
Buyer's calculation of the Purchase Price (less any amount deposited in escrow
by Buyer pursuant to Section 3.5) shall be deposited in escrow with the Escrow
Agent pending a determination of the final Purchase Price.  In such event the
final Purchase Price shall be determined either (i) by subsequent agreement of
the parties, or (ii) by binding arbitration pursuant to an arbitration
proceeding initiated and conducted substantially in accordance with the
procedures set out in Section 11.4 hereof.  In the event arbitration is
necessary to determine the Purchase Price, prior to initiating the arbitration,
each party shall furnish to the other a statement of such party's calculation of
the Purchase Price.  All 

                                       19
<PAGE>
 
fees and expenses of the arbitration, including attorneys' fees, expert witness
fees and all other out-of-pocket expenses of both parties, shall be paid by the
party whose calculation of the Purchase Price bears the greatest difference from
the Purchase Price determined by the arbitrator. The award of the arbitrator
shall not be subject to appeal or judicial review of any nature and shall be
promptly furnished to the Escrow Agent who shall make distribution of the
escrowed funds in a manner consistent with such award.

     12.5 LETTERS IN LIEU. Seller shall execute and deliver to Buyer at the

orders or letter in lieu thereof directing all purchasers of production to make

funds relating to operations on or production from the Interests prior to the
Effective Time, or Seller receives any funds relating to operations on or
production from the Interests after the Effective Time, then the party receiving
such funds shall account therefor and pay the same to the other party promptly
after receipt thereof.  Likewise, if Buyer shall be required to pay any amount
relating to items of the Interests which accrued to the owner of the Interests
before the Effective Time, or if Seller shall be required to pay any amount (not
otherwise prohibited by the ten-ns of this Agreement) relating to items of the
Interests which accrued to the owner of the Interests after the Effective Time,
then the party making such payment shall invoice the other party for the amount
of such payment and the party receiving such invoice promptly shall pay the
same.  Notwithstanding the foregoing, there shall be no accounting for amounts
received or paid which have already been taken into account in calculating the
Purchase Price.  In determining the amount paid by a party accruing during a
period of time in respect of ad valorem taxes, the taxes shall be prorated as
provided in Section 7.7.

                           GOTHIC ENERGY CORPORATION
                           -------------------------

Void after February 18, 1999                    Right to Purchase 200,000 Shares
Warrant No. 97-1                                of Common Stock


          Gothic Energy Corporation, an Oklahoma corporation (the "Company"),
hereby certifies that, for value received, Norse Exploration, Inc. and Norse
Pipeline, Inc., or registered assigns, is entitled, subject to the terms set
forth below, to purchase from the Company at any time or from time to time
before 5 P.M., New York City time, on or before February 18, 1999, 200,000 fully
paid and non-assessable shares of the Common Stock, par value $.01 per share, of
the Company, at a price (the "Purchase Price") of $2.50 per share,  which amount
is equal to the closing sale price of the Company's Common Stock on the Nasdaq
SmallCap Market on December 10, 1996.  The term "Common Stock" shall mean,
unless the context otherwise requires, the stock and, under certain
circumstances, other securities and property at the time receivable upon the
exercise of this Warrant.

     1.   The Warrants. As used herein, the term "Issue Date" shall mean
          ------------                                                  
December 11, 1996 and the term "Warrant" refers to this Warrant and "Warrants"
refers to all of the substantially identical warrants issued concurrently
herewith unless the 
<PAGE>
 
context should otherwise require. This Warrant has been issued as partial
consideration for the assets purchased by the Company pursuant to the Sale and
Purchase Agreement dated December 11, 1996 between the Company and Norse
Exploration, Inc. and Norse Pipeline, Inc.

     2.   Exercise of Warrant; Partial Exercise. This Warrant may be exercised
          -------------------------------------
for the full number of shares of Common Stock (herein referred to as "Warrant
Stock") at the time called for hereby and exercisable as herein provided by the
holder surrendering this Warrant, properly endorsed, to the Company at its
principal office in Tulsa, Oklahoma, or to the Company's transfer agent,
American Stock Transfer & Trust Company, 40 Wall Street, New York, New York
10005, or successor transfer agent, accompanied by payment, in cash or by
certified or official check, payable to the order of the Company, of the sum
(the "Sum") obtained by multiplying (a) the number of shares of Common Stock
called for on the face of this Warrant or with respect to which this Warrant is
exercisable by (b) the Purchase Price.

          This Warrant may be exercised for less than the full number of shares
of Common Stock at the time called for hereby and exercisable hereunder by such
a surrender except that the number of shares receivable upon the exercise of
this Warrant as a whole, and the amount payable upon the exercise of this
Warrant as a whole, shall be proportionately reduced. Upon any such partial
exercise, the Company, at its expense, will forthwith issue to the holder hereof
a new Warrant or Warrants of like tenor calling in the aggregate on their face
for the number of shares of Common Stock issuable upon exercise of this Warrant
less the number of shares purchased on such exercise, issued in the name of the
holder hereof or as such holder (upon payment by such holder of any applicable
transfer taxes) may direct; provided that, in case this Warrant shall not have
been registered under the Securities Act of 1933, as amended (the "Act"), the
Company shall not be obligated to issue and deliver any Warrant or Warrants to
or in the name of any person other than the holder of this Warrant unless, in
the opinion of counsel to the Company, such Warrant or Warrants may be so issued
and delivered without registration under the Act.
 
     3.   Delivery of Stock Certificates on Exercise. As soon as practicable
          ------------------------------------------                        
after the exercise of this Warrant and payment of the Purchase Price, the
Company, at its expense (including the payment by it of any applicable issue
tax) will cause to be issued in the name of and delivered to the holder hereof,
or as such holder (upon payment by such holder of any applicable transfer taxes)
may direct, a certificate or certificates for the number of full shares of
Common Stock to which such holder would be entitled upon such exercise, plus, in
lieu of any fractional shares to which such holder would otherwise be entitled,
cash equal to such fraction multiplied by the greater of (i) the then current
market value of one full share, or (ii) the book value per share as of the close
of the Company's most recent fiscal quarter, provided that, in case such 


                                      -2-
<PAGE>
 
shares or other securities shall not have been registered under the Act, (i) the
Company may require that such holder furnish to the Company a written statement
that such holder is purchasing such shares or other securities for such holder's
own account for investment and not with a view to the distribution thereof
(other than sales permitted by the Act or the rules and regulations thereunder
to be made without registration), subject, nevertheless, to any requirement of
law that the disposition of the property of such holder shall at all times be
within its own control, and further agreeing that the legend hereinafter
provided shall appear on the certificates for the shares of Common Stock and be
applicable to a transfer thereof, (ii) the Company shall not be obligated to
issue and deliver any certificate for Common Stock to or in the name of any
person other than the holder of this Warrant unless, in the opinion of counsel
to the Company, such certificate may be so issued and delivered without
registration under the Act, and (iii) the Company may place on each certificate
delivered to any such person a legend substantially identical to the legend
appearing at the beginning of this Warrant, applicable however to the Common
Stock, evidencing that the shares represented thereby have not been registered
under the Act.

     4.   Adjustment for Dividends in Other Stock, Property; Reclassifications.
          -------------------------------------------------  -----------------
In case at any time or from time to time after the Issue Date, the holders of
the Common Stock of the Company (or any shares of stock or other securities at
the time receivable upon the exercise of this Warrant) shall have received, or,
on or after the record date fixed for the determination of eligible
stockholders, shall have become entitled to receive, without payment therefor,

          (i)   other or additional stock or other securities or property (other
than cash) by way of dividend or spin-off,

          (ii)  any cash paid or payable out of capital or paid-in surplus or
surplus created as a result of a revaluation, or

          (iii) other or additional stock or other securities or property
(including cash) by way of stock-split,  split-up, reclassification, combination
of shares or similar corporate rearrangement,

(other than additional shares of Common Stock of the Company, or any other stock
or securities into which such Common Stock shall have been changed, or any other
stock or securities convertible into or exchangeable for such Common Stock or
such other stock or securities, adjustments in respect of which shall be covered
by the terms of Paragraph 5), then and in each such case, the holder of this
Warrant, upon the exercise hereof as provided in Paragraph 2, shall be entitled
to receive the amount of stock and other securities and property (including cash
in the cases referred to in clauses (ii) and (iii) above) which such holder
would hold on the date of such exercise if on the Issue 

                                      -3-
<PAGE>
 
Date he had been the holder of record of the number of shares of Common Stock of
the Company called for on the face of this Warrant and had thereafter, during
the period from the Issue Date to and including the date of such exercise,
retained such shares and/or all other or additional stock and other securities
and property (including cash in the cases referred to in clauses (ii) and (iii)
above) receivable by him as aforesaid during such period, giving effect to all
adjustments called for during such period by Paragraph 5.

     5.   Adjustment for Reorganization, Consolidation, Merger.   In case of any
          ----------------------------------------------------                 
reorganization of the Company (or any other corporation, the stock or other
securities of which are at the time receivable on the exercise of this Warrant)
after the Issue Date or in case, after the Issue Date, the Company (or any other
corporation) shall consolidate with or merge with or into  another corporation,
whether or not the Company shall be the surviving corporation, or convey all or
substantially all its assets to another corporation, then and in each such case
the holder of this Warrant, upon the exercise hereof as provided in Paragraph 2
at any time after the consummation of such reorganization, consolidation, merger
or conveyance, shall be  entitled to receive, in lieu of the stock or other
securities and property receivable upon the exercise of this Warrant prior to
such consummation, the stock or other securities or property (including cash) to
which such holder would have been entitled upon such consummation if such holder
had exercised this Warrant immediately prior thereto, all subject to further
adjustment as provided in Paragraph 4; in each such case, the terms of this
Warrant shall be applicable to the shares of stock or other securities or
property receivable upon the exercise of this Warrant after such consummation.

     6.   No Dilution or Impairment.  The Company will not, by amendment of its
          -------------------------                                           
certificate of incorporation or through reorganization, consolidation, merger,
dissolution, issue or sale of securities, sale of assets or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms
of the Warrants, but will at all times in good faith assist in the carrying out
of all such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holders of the Warrants
against dilution or other impairment.  Without limiting the generality of the
foregoing, the Company (a) will not increase the par value of any shares of
stock receivable upon the exercise of the Warrants above the amount payable
therefor upon such exercise, (b) will take all such action as may be necessary
or appropriate in order that the Company may validly and legally issue fully
paid and non-assessable shares upon the exercise of all Warrants at the time
outstanding, and (c) will take no action to amend its certificate of
incorporation which would change to the detriment of the holders of Common Stock
(whether or not any Common Stock be at the time outstanding) the dividend or
voting rights of the Company's Common Stock as constituted on the Issue Date.

     7.   Officer's Certificate as to Adjustments.  In each case of an
          ---------------------------------------                    
adjustment in the Purchase Price (including the adjustment referred to in the
first paragraph of this Warrant) or in the shares of Common Stock or other
stock, securities or property receivable on the exercise of the Warrants, the
Company, at its expense, shall cause its principal financial officer to compute
such adjustment in accordance with the terms of the Warrants and prepare a
certificate setting forth such adjustment and showing in detail the facts upon
which such adjustment is based, including, without limitation, a statement of
the Adjusted Purchase Price.  The Company will forthwith mail a copy of each
such certificate to each holder of a Warrant at the time outstanding.

     8.   Notices of Record Date.  In case
          ----------------------         

          (i)   the Company shall take a record of the holders of its Common
Stock (or other stock or securities at the time receivable upon the exercise of
the Warrants) for the purpose of entitling them to receive any dividend (other
than a cash dividend), or other distribution, or any right to subscribe for or
purchase any shares of stock of any class or any other securities, or to receive
any other right; or

          (ii)  of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or
merger of the Company with or into another corporation, or any conveyance of all
or substantially all of the assets of the Company to another corporation; or

          (iii) of any voluntary dissolution, liquidation or winding-up of the
Company;

then, and in each such case, the Company will mail or cause to be mailed to each
holder of a Warrant at the time outstanding a notice specifying, as the case may
be, (a) the date on which a record is to be taken for the purpose of such
dividend, distribution or right, and stating the amount and character of such
dividend, distribution or right, or (b) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up is to take place, and the time, if any is to be fixed, as of which
the holders of record of Common Stock (or such other stock or securities at the
time receivable upon the exercise of the Warrants) shall be entitled to exchange
their shares of Common Stock (or such other stock or securities) for securities
or other property deliverable upon such reorganization, reclassification,

     9.   Registration of Common Stock
          ----------------------------

          9.1  Incidental Registrations.
               ------------------------ 


          (a)  In the event the Company hereafter shall take action to register
any of its equity securities under the Act for the purpose of registering under
the Act securities of the Company to be sold by security-holders of the Company,
the Company agrees that it will give to the holder or holders of the Warrants
and any shares previously issued on exercise thereof notice that such
registration of securities is to be effected and that registration of the shares
of Common Stock of the Company issuable on exercise of the Warrants will then be
effected by the Company under the then applicable law and regulations and
practices of the Securities and Exchange Commission or other governmental agency
substituted therefor.  All of the shares of Common Stock issuable on exercise of
such Warrants and all shares of Common Stock previously issued to such Holder on
exercise of a Warrant held by such holder will be included in such registration
unless, within 15 days of the receipt of such notice, such holder notifies the
Company in writing that such holder desires none or only a portion (specifying
the number) of the shares to be included in such registration whereupon the
Company shall include in such registration only the number of shares specified
in such notice from the holder. The Company will, at its own expense, take
action to register thereunder the shares of Common Stock to be registered and
such other action as may be requested by such holder to effect qualification
under and compliance with any state laws or other governmental requirements, as
above provided.

          (b)  Any holder whose securities shall be included in the Company's
registration under the Act pursuant to subsection (a) of this Paragraph 9.1
shall furnish to the Company such information regarding his holdings of shares
of Common Stock to be registered and the proposed manner of distribution thereof
as the Company may request in writing and as shall be required in connection
with any registration, qualification or compliance referred to in subsection (a)
of this Paragraph 9.1 and shall otherwise cooperate with the Company in
connection with such registration, qualification or compliance.  The Company, at
its expense, will furnish to holders of shares of Common Stock included in such
registration such number of prospectuses, offering circulars or other documents
incident to any registration, qualification or compliance referred to in this
Paragraph 9.1 as such holders from time to time reasonably may request, and will
indemnify and defend each such holder of shares of Common Stock being sold by
any such holder (and any person who controls such holder within the meaning of
Section 15 of the Act) against all claims, losses, damages, liabilities and
expenses resulting from any untrue statement or alleged untrue statement of a
material fact contained therein (or in any related registration statement,
notification or the like) or from any omission or alleged omission to state
therein a material fact 

                                      -6-
<PAGE>
 
required to be stated therein or necessary to make the statements therein not
misleading, except insofar as the same may have been based upon information
furnished in writing to the Company by such holder expressly for use therein,
and with respect to such information furnished to the Company, such holder will
indemnify and defend the Company against all claims, losses, damages,
liabilities and expenses resulting from any untrue statement or alleged untrue
statement of a material fact contained therein or any omission or alleged
omission to state a material fact required to be stated or necessary to make the
information not misleading. Notwithstanding anything herein contained, the
Company shall not be obligated to pay any underwriting or brokers' discounts or
commissions applicable to the holder's shares of Common Stock or fees or
disbursements of counsel to the selling stockholders.

          (c)  Notwithstanding anything herein to the contrary, the Company
shall not be obligated to offer to include the shares of Common Stock issuable
or previously issued on exercise of such warrants on any occasion other than the
first occasion after the date hereof that the Company files a registration
statement under the Act relating to securities of the Company to be sold by
security-holders of the Company. In addition, the Company's obligations under
this Section 9 shall terminate on the date when all of the shares issuable and
issued on exercise of this Warrant are permitted to be sold without registration
pursuant to Rule 144(k) under the Act or any similar successor rule.

          9.2. Registration Procedures.  If and whenever the Company is
               -----------------------                                 
required to use reasonable efforts to effect or cause the registration of any
Common Stock under the  Act as provided in this Section 9, the Company will, as
expeditiously as possible:

          (a)  prepare and file with the Securities and Exchange Commission a
registration statement with respect to such Common Stock and use reasonable
efforts to cause such registration statement to become effective;

          (b)  prepare and file with the Securities and Exchange 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 a period of not less than nine months or such shorter
period in which the disposition of all securities in accordance with the
intended methods of disposition by the seller or sellers thereof set forth in
such registration statement shall be completed, and to comply with the
provisions of the Act (to the extent applicable to the Company) with respect to
such dispositions;

          (c)  furnish to each seller of such Common Stock such number of copies
of such registration statement and of each such amendment and supplement thereto
(in each case including all exhibits), such number of copies of the prospectus
included in such registration statement (including each preliminary prospectus),
in conformity with 

                                      -7-
<PAGE>
 
the requirements of the Act, and such other documents, as such seller may
reasonably request, in order to facilitate the disposition of the Common Stock
owned by such seller;

          (d)  use of its reasonable efforts to register or qualify such Common
Stock covered by such registration statement under such other 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
Common Stock owned by such seller, except that the Company will not for any such
purpose be required to qualify generally to do business as a foreign corporation
in any jurisdiction wherein it would not, but for the requirements of this
Paragraph 9.2(d) be obligated to be qualified, to subject itself to taxation in
any such jurisdiction, or to consent to general service of process in any such
jurisdiction; and

          (e)  notify each seller of such Common Stock at any time when a
prospectus relating thereto is required to be delivered under the  Act, of the
happening of any event 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 will prepare a supplement or amendment
to such prospectus so that, as thereafter delivered to the purchasers of such
Common Stock, such prospectus will not contain an untrue statement of a material
fact or omit to state any fact necessary to make the statements therein not
misleading.

          9.3  Registration and Selling Expenses.
               ---------------------------------

H. Huffman & Co.

Oklahoma City, Oklahoma 73116

ATTN: Huston Huffman, Jr.

     RE:  Offer to Purchase Certain Oil and Gas Properties and Partnership
          ----------------------------------------------------------------
          Interest
          --------
Gentlemen:

     This letter when accepted shall confirm the agreement between H. Huffman &
Co., an Oklahoma limited partnership ("Seller"), and Gothic Energy Corporation,
an Oklahoma corporation ("Buyer"), with respect to Seller's sale to Buyer of
those oil and gas properties described below, including all undeveloped oil and
gas leasehold acreage corresponding to all such wells, together with all of
Seller's 10.97% general partnership interest in Sycamore Gas System, an Oklahoma
general partnership ("Sycamore").

     1.  Sale and Purchase.  For good and valuable consideration and subject to
         -----------------                                                     
and in accordance with the terms and conditions of this Agreement, Seller hereby
agrees to sell and convey to Buyer and Buyer agrees to purchase and acquire from
Seller all of Seller's right, title and interest in and to the wells, lands and
leasehold interests described in Exhibit "A" hereto, including, without
limitation, all undeveloped oil and gas leasehold acreage, acreage comprising
the spacing unit for such wells, and well facilities and equipment used in
conjunction with such wells to the extent such interests are  owned by or
allocable to Seller, specifically including all operating and other contract
rights associated with such wells (collectively the "Properties").  The
Properties do not include, and there is expressly reserved unto Seller, all
mineral interests, royalties, overriding royalties and similar interests owned
in lands and leases included in the Properties.  The net revenue interests
attributable to such excluded interests are not included in the net revenue
interests shown in Exhibit A.  In addition, Seller hereby agrees to sell to
Buyer Seller's 10.97% general partnership interest in Sycamore (the "Sycamore
Interest").

     2.  Effective Time.  The effective time of the sale and purchase
         --------------                                              
contemplated by this Agreement shall be January 1, 1997, at 7:00 a.m. Central
Standard Time (the "Effective Time"). Unless otherwise provided in this
Agreement, Buyer shall be entitled to any amounts realized from and accruing to
the Properties which are attributable to periods of production on and after the
Effective Time and shall be responsible for all expenses for the development and
operation of the Properties attributable to periods on and after the Effective
Time. Seller shall be entitled to all amounts realized from and accruing to the
Properties which are attributable to periods of production prior to the
Effective Time and shall be responsible for all expenses for the development and
operation of the Properties attributable to periods prior to the Effective Time.

     3.  Closing.  Unless extended by mutual written agreement of the parties,
         -------                                                              
the closing of the sale and purchase contemplated by this agreement shall occur
on or before February 14, 1997 (the "Closing"), in the offices of Seller,
located at 301 N.W. 63rd Street, Suite 510, Oklahoma City, Oklahoma, or at such
other place as may be agreed on by the parties.

     4.  Purchase Price.  Subject to adjustments as provided in this Agreement,
         --------------                                                        
the purchase price payable by Buyer for the Properties and the Sycamore Interest
shall be $5,750,000 (the "Purchase Price"), which sum shall be

H.Huffman & Co.

allocated among the Properties and the well equipment and other personalty,
including the Sycamore Interest (the "Personalty") as set forth in Exhibit "A"
(the "Allocated Values") and shall be fully payable by Buyer at Closing.
Immediately upon the execution of this letter agreement by Seller, Buyer shall
deliver to Seller in immediately available funds a deposit in the sum of
$287,500.00 (5% of the Purchase Price) as a deposit toward the Purchase Price
(the "Deposit").  In the event that Buyer shall fail to close the transaction
contemplated hereby in accordance with the terms of this agreement, and provided
that the conditions precedent to the obligations of Buyer set forth herein, have
been fulfilled or Seller is ready, willing and able to comply with all such
conditions precedent, Seller shall be entitled to retain this Deposit as
liquidated damages.  The parties hereto agree that the amount of damages caused
by Buyer's breach or failure to close would be very difficult to calculate
exactly and that the provision for liquidated damages herein is not a penalty
provision.  Such right to liquidated damages shall be Seller's sole remedy
hereunder.

     5.  Access to Information.  From and after the date of Seller's acceptance
         ---------------------                                                 
of this Agreement, Buyer shall be allowed, at its expense, to examine in
Seller's offices or such other place where pertinent records are maintained, all
land, tax, legal, contract, production, engineering, geological, geophysical,
accounting and revenue, and any other files or data, including computer retained
data, relating to the Properties, to verify title and economics. Buyer shall be
entitled to all original files relating to the Properties at Closing.

     6.  Title Review.  Buyer shall have until February 1, 1997, or fifteen (15)
         ------------                                                           
days prior to closing (the "Title Review Period") within which to conduct title
due diligence with respect to the Properties (whether through the examination of
lease files, abstracts, landman's ownership reports or physical inspection of
the documents indexed against the Properties. If the records or materials
furnished to or examined by Buyer reflect the existence of any discrepancy in
working or net revenue interests or any material encumbrance, encroachment or
defect in title that renders title to all or any portion of the Properties, in
the opinion of Buyer or its attorneys, less than defensible, and which Buyer
does not waive (the "Title Defects"), written notice of such specific Title
Defects shall be given by Buyer to Seller on or before expiration of the Title
Review Period. No matter shall be construed as a Title Defect unless so
construed under generally accepted oil and gas industry title examination
standards for the State of Oklahoma, but Title Defects shall specifically
include any preferential right to purchase which is exercised or outstanding. If
Title Defects shall be timely asserted by Buyer, Seller may, but shall not be
obligated to, attempt to cure or remove all such Title Defects, at Seller's sole
expense, prior to Closing. With respect to any Title Defect which remains
uncured forty-eight (48) hours prior to Closing, then (i) Buyer shall propose an
adjustment to the Purchase Price (which shall not exceed the Allocated Value of
the affected Property) which Buyer believes represents the difference between
the Allocated Value and the true value given the existence of the unresolved
Title Defect, (ii) Seller may accept Buyer's proposed adjustment to the Purchase
Price or may negotiate with Buyer a lesser adjustment to the Purchase Price, and
(iii) if Seller and Buyer cannot agree upon a reduced Purchase Price, the
Property affected by the Title Defect shall not be sold to Buyer, but shall be
retained by Seller and the Purchase Price shall be reduced by the Allocated
Value assigned to such Property in Exhibit "A" hereto.

     7.  Environmental.  Buyer shall have until February 1, 1997, or fifteen
         -------------                                                      
(15) days prior to closing (the "Environmental Review Period"), within which to
conduct environmental due diligence with respect to the Properties.  If
environmental defects shall be timely asserted by Buyer, Seller may, but shall
not be obligated to, attempt to cure or remedy such defects at Seller's sole
expense prior to Closing.  With respect to any environmental defect which
remains uncured forty-eight (48) hours prior to Closing, then (i) Buyer shall
propose an adjustment to the Purchase Price (which shall not exceed the
allocated value of the affected property) which Buyer believes represents the
difference between the allocated value and the true value given the existence of
the unresolved environmental defect; (ii) Seller may accept Buyer's proposed
adjustment to the Purchase Price or may negotiate with Buyer at a lesser
adjustment to the Purchase Price; and (iii) if Seller and Buyer cannot agree
upon a reduced Purchase Price, the

     8.  Representations of Seller.  Seller represents and warrants as follows:
         -------------------------                                             

           (a) Legal Power and Ownership. Seller has the full power and right to
               -------------------------                                        
     sell and convey the Properties pursuant to the terms of this Agreement and
     to perform Seller's other obligations under this Agreement.

           (b) Compliance with Laws.  To Seller's knowledge, the Properties have
               --------------------                                             
     been operated in compliance, in all material respects, with all laws,
     rules, regulations, ordinances, orders and permits relating to the
     Properties, including all state and federal regulations, ordinances, orders
     and permits relating to the Properties, including all state and federal
     regulations for the protection of the environment and the protection of the
     safety and health of persons and property pertaining to the Properties.
     Seller is aware of no administrative order or investigative action of the
     Environmental Protection Agency, the Oklahoma Corporation Commission or
     other state agency relative to the Properties which would require that
     remedial measures be taken for the clean-up, containment of hazardous
     waste, or the curtailment of production.

           (c) No Conflicts.  Seller's execution of this Agreement and
               ------------                                           
     consummation of the transactions contemplated herein will not violate nor
     be in conflict with any material provision of any agreement or instrument
     to which Seller is a party or is bound, or any judgment, decree, order,
     statute, rule or regulation applicable to Seller.

           (d) Production Sales Contracts.  Seller is not obligated by virtue
               --------------------------

     arrangement to deliver oil or gas produced from and after the Effective
     time with respect to any Property without receiving payment therefor in the
     ordinary course of business. No proceeds of production from any Property
     prior to the Effective Time are subject to any refund as a result of the
     price paid therefor exceeding the applicable maximum lawful prices. No
     purchaser of production from any Property has placed in suspense any funds
     owing to Seller which are attributable to any period of time subsequent to
     the Effective Time. Seller has not initiated, consummated or waived the
     "Good Faith Negotiation Procedure" under FERC Order 451 with respect to any
     Property and Seller is not obligated to make any refunds or other payments
     after the Effective Time with respect to any take-or-pay settlements
     affecting any Property.

           (e) Litigation.  There are no demands, claims, notices of violations,
               ----------                                                       
     filings, governmental investigations, administrative proceedings, actions,
     causes of action, suits or other legal proceedings pending or, to Seller's
     knowledge, threatened against Seller with respect to any of the Properties.

           (f) Leases.  To Seller's knowledge, all rentals, royalties,
               ------                                                 
     overriding royalty interests and other payments due under each oil and gas
     lease comprising the Properties have been promptly and fully paid.

     9.  Representations of Buyer.

           (d) Taxes.  Ad valorem, property, production, severance, and similar
               -----

     14. Indemnities.
         ----------- 

          (a) Indemnity by Seller.  Subject to the limitations contained herein
              -------------------                                              
     and as set forth in subparagraph (c) below, Seller shall indemnify and hold
     harmless Buyer, its affiliates, successors and assigns, from and against
     any damage, liability, loss, cost, expense, attorney's fees, judgment, or
     deficiency that Buyer shall pay or become obligated to pay arising out of
     or resulting from, (i) an inaccuracy in any representation of the breach of
     any warranty of Seller under this Agreement; or (ii) a failure of Seller to
     duly perform or observe any term, provision, covenant, or agreement to be
     performed or observed by Seller hereunder; however, in no event shall
     Seller's indemnification obligation cover or extend to any matter relating
     to title to or the environmental condition of the Properties.

          (b) Indemnity by Buyer.  Subject to the limitations contained herein
              ------------------                                              
     and as set forth in subparagraph (c) below, Buyer shall indemnify and hold
     harmless Seller, their representatives and assigns, from and against any
     damage, liability, loss, cost, expense, attorney's fees, judgment, or
     deficiency that Seller shall pay or become obligated to pay arising out of
     or resulting from (i) an inaccuracy in any representation or the breach of
     any warranty of Buyer under this Agreement; (ii) a failure of Buyer to duly
     perform or observe any term, provision, covenant, or agreement to be
     performed or observed by Buyer hereunder; (iii) Buyer's ownership,
     management or control of the Properties after Closing; or (iv) violations
     by Buyer of any state or federal environmental laws; provided, however,
     that in no event shall Buyer have any liability for any obligation with
     respect to any tortious actions, breaches of contract or other wrongful
     acts of Seller.

          (c) Limitations on Indemnities.  No claim or indemnity shall be made
              --------------------------                                      
     hereunder until the amounts involved, per Property and per occurrence,
     actual or alleged, exceed $20,000; and, any such claim for indemnity shall
     then be limited to the amount by which such claim exceeds $20,000.

          (d) Right to Contest and Defend.  The indemnitor hereunder shall be
              ---------------------------                                    
     entitled, at its cost and expense, to contest and defend by all appropriate
     legal proceedings, any claim with respect to which it is called upon to
     indemnify the other party hereunder; provided, that notice of the intention
     to so contest shall be delivered by the indemnitor to the indemnitee within
     15 calendar days from the date indemnitor received notice of the
     indemnitee's claim.  Any such contest may be conducted in the name and on
     behalf of the indemnitor or the indemnitee as may be appropriate.  Such
     contest shall be conducted by reputable counsel employed by the indemnitor,
     but the indemnitee shall have the right to participate in such proceedings
     and to be represented by counsel of its own choosing at its sole cost and
     expense.  If the indemnitee joins in any such contest, the
<PAGE>
 
H.Huffman & Co.
December 13, 1996
Page 7

     indemnitor shall have full authority to determine all action to be taken
     with respect thereto; provided, however, that the indemnitor shall not have
     the authority to subject the indemnitee to any obligation whatsoever, other
     than the performance of purely ministerial tasks (e.g., the execution of
     settlement agreements and other documentation) or obligations not involving
     significant expense.  If the indemnitor does not elect to contest any such
     claim, the indemnitor shall be bound by the result obtained with respect
     thereto by the indemnitee.

     15. Balancing.  The Purchase Price specified herein is based, in part, upon
         ---------                                                              
the assumption there will not exist, at the Effective Time, a material net gas
imbalance with respect to the Properties.  To the extent net gas overproduction
with respect to the Properties is discovered to be more or less than 1,000 Mcf,
the Purchase Price shall be adjusted at Closing downward by $1.50 (net of
royalties and taxes) for each Mcf by which Seller's interest in the Properties
is overproduced by more than 1,000 Mcf at the Effective Time.  Any adjustments
not made at Closing due to gas imbalances shall be made by the appropriate party
not later than the Final Settlement.

     16. Maintenance of Properties.  Seller will use its reasonable best efforts
         -------------------------                                              
as a non-operator to cause the Properties to be maintained and operated, from
and after the date of this Agreement through Closing, in a good and workmanlike
manner; will pay or cause to be paid all bills and invoices for all costs and
expenses incurred in connection with the development, operation and maintenance
of the Properties before bills or invoices become delinquent; provided, however,
that Seller shall not (i) enter into any new commitment with respect to any of
the Properties which shall require a gross expenditure of $10,000 for any single
operation without the consent of Buyer, which consent shall not be unreasonably
withheld, or (ii) waive, compromise or settle any right or claim that would
adversely affect the ownership, operation or value of any of the Properties.
Seller will use its reasonable best efforts as a non-operator to support the
election of Buyer (or its designee) as operator under applicable joint operating
agreements and regulatory orders of all wells included within the Properties.

     17. Transfer Orders.  At Closing, Seller agrees to execute such transfer
         ---------------                                                     
orders, letters in lieu of transfer orders, or other documents as may be
necessary to effect payment of revenues to Buyer.

     18. Miscellaneous.
         --------------

          (a) Seller and Buyer shall each pay their own expenses and costs
     (including, without limitation, any and all broker's or finder's fees and
     commissions and attorney's fees) in connection with this Agreement and the
     transactions contemplated hereby, except as otherwise provided herein.

          (b) This Agreement shall be construed in accordance with and shall be
     governed by the substantive laws of the State of Oklahoma.

          (c) Buyer, at its option, may assign all or any portion of its rights
     under this Agreement to any third party, but shall remain liable for
     Buyer's obligations hereunder unless specifically released by Seller. This
     Agreement shall be binding upon the undersigned and their respective
     successors and assigns.

          (d) All representatives, warranties and covenants contained in this
     Agreement shall be deemed to survive Closing.

     RE:  Offer to Purchase Certain Oil and Gas Properties
          ------------------------------------------------

Dear Mr. Rich:

     This letter when accepted shall confirm the agreement between Horizon Gas

Oklahoma corporation ("Buyer"), with respect to Seller's sale to Buyer of those
oil and gas properties described below, including all undeveloped oil and gas
leasehold acreage corresponding to all such wells.

     1.   Sale and Purchase.  For good and valuable consideration and subject to
          -----------------                                                     
and in accordance with the terms and conditions of this Agreement, Seller hereby
agrees to sell and convey to Buyer and Buyer agrees to purchase and acquire from
Seller all of Seller's right, title and interest in and to the wells, lands and
leasehold interests described in Exhibit "A" hereto, including, without
limitation, mineral interests, overriding royalty interests, all undeveloped oil
and gas leasehold acreage, acreage comprising the spacing unit for such wells,
and well facilities and equipment used in conjunction with such wells to the
extent such interests are  owned by or allocable to Seller, specifically
including all operating and other contract rights associated with such wells
(collectively the "Properties").

     2.   Effective Time.  The effective time of the sale and purchase
          --------------                                              
contemplated by this Agreement shall be January 1, 1997, at 7:00 a.m. Central
Standard Time (the "Effective Time"). Unless otherwise provided in this
Agreement, Buyer shall be entitled to any amounts realized from and accruing to
the Properties which are attributable to periods of production on and after the
Effective Time and shall be responsible for all expenses for the development and
operation of the Properties attributable to periods on and after the Effective
Time. Seller shall be entitled to all amounts realized from and accruing to the
Properties which are attributable to periods of production prior to the
Effective Time and shall be responsible for all expenses for the development and
operation of the Properties attributable to periods prior to the Effective Time.

     3.   Closing.  Unless extended by mutual written agreement of the parties,
          -------                                                              
the closing of the sale and purchase contemplated by this agreement shall occur
on or before February 14, 1997 (the "Closing"), in the offices of Buyer, located
at 5727 South Lewis Avenue, Suite 700, Tulsa, Oklahoma, or at such other place
as may be agreed on by the parties.

     4.   Purchase Price.  Subject to adjustments as provided in this Agreement,
          --------------                                                        
the purchase price payable by Buyer for the Properties shall be $10,000,000 (the
"Purchase Price"), which sum shall be allocated among the Properties and the
well equipment and other personalty (the "Personalty") as set forth in Exhibit
"A" (the "Allocated Values") and shall be fully payable by Buyer at Closing.

     5.   Access to Information.  From and after the date of Seller's acceptance
          ---------------------                                                 
of this Agreement, Buyer shall be allowed, at its expense, to examine in
Seller's offices or such other place where pertinent records are maintained, all
land, tax, legal, contract, production, engineering, geological, geophysical,
accounting and revenue, and any other files

or data, including computer retained data, relating to the Properties, to verify
title and economics. Buyer shall be entitled to all original files relating to
the Properties at Closing.

     6.   Title Review.  Buyer shall have until February 1, 1997, or fifteen 
          ------------
(15) days prior to closing (the "Title Review Period") within which to conduct
title due diligence with respect to the Properties whether through the
examination of lease files, abstracts, landman's ownership reports or physical
inspection of the documents indexed against the Properties. If the records or
materials furnished to or examined by Buyer reflect the existence of any
discrepancy in working or net revenue interests or any material encumbrance,
encroachment or defect in title that renders title to all or any portion of the
Properties, less than defensible, and which Buyer does not waive (the "Title
Defects"), written notice of such specific Title Defects shall be given by Buyer
to Seller on or before expiration of the Title Review Period. No matter shall be
construed as a Title Defect unless so construed under generally accepted oil and
gas industry title examination standards for the State of Oklahoma, but Title
Defects shall specifically include any preferential right to purchase which is
exercised or outstanding. If Title Defects shall be timely asserted by Buyer,
Seller may but shall not be obligated to make reasonable efforts to cure all
such title defects at Seller's sole expense prior to closing. With respect to
any Title Defect which remains uncured forty-eight (48) hours prior to Closing,
then (i) Buyer shall propose an adjustment to the Purchase Price (which shall
not exceed the Allocated Value of the affected Property) which Buyer believes
represents the difference between the Allocated Value and the true value given
the existence of the unresolved Title Defect, (ii) Seller may accept Buyer's
proposed adjustment to the Purchase Price or may negotiate with Buyer a lesser
adjustment to the Purchase Price, and (iii) if Seller and Buyer cannot agree
upon a reduced Purchase Price, the Property affected by the Title Defect shall
not be sold to Buyer, but shall be retained by Seller and the Purchase Price
shall be reduced by the Allocated Value assigned to such Property in Exhibit "A"
hereto. In the event that the Purchase Price shall be reduced by ten percent
(10%) in the aggregate, Seller may at its option terminate this agreement, and
each party hereto shall bear its own costs connected therewith.

     7.   Environmental.  Buyer shall have until February 1, 1997, or fifteen
          -------------                                                      
(15) days prior to closing (the "Environmental Review Period"), within which to
conduct environmental due diligence with respect to the Properties.  If
environmental defects shall be timely asserted by Buyer, Seller may but shall
not be obligated to make reasonable efforts to cure all such environmental
defects at Seller's sole expense prior to closing.  With respect to any
environmental defect which remains uncured forty-eight (48) hours prior to
Closing, then (i) Buyer shall propose an adjustment to the Purchase Price (which
shall not exceed the allocated value of the affected property) which Buyer
believes represents the difference between the allocated value and the true
value given the existence of the unresolved environmental defect; (ii) Seller
may accept Buyer's proposed adjustment to the Purchase Price or may negotiate
with Buyer at a lesser adjustment to the Purchase Price; and (iii) if Seller and
Buyer cannot agree upon a reduced Purchase Price, the property affected by the
environmental defect shall not be sold to Buyer, but shall be retained by Seller
and the Purchase Price shall be reduced by the allocated value assigned to such
property in Exhibit "A" hereto.  In the event that the Purchase Price shall be
reduced by ten percent (10%) in the aggregate, Seller may at its option
terminate this agreement, and each party hereto shall bear its own costs
connected therewith.

     8.   Representations of Seller.  Seller represents and warrants as follows:
          -------------------------                                             

          (a)  Legal Power and Ownership. Seller has the full power and right to
              -------------------------                                        
     sell and convey the Properties pursuant to the terms of this Agreement and

          (b)  Compliance with Laws.  The Properties have been operated in

     protection of the environment and the protection of the safety and health
     of persons and property pertaining to the Properties. Seller is aware of no
     administrative order or investigative action of the Environmental
     Protection Agency, the Oklahoma Corporation Commission or other state
     agency relative to the Properties which would require that remedial
     measures be taken for the clean-up, containment of hazardous waste, or the
     curtailment of production.

     time with respect to any Property without receiving payment therefor in the
     ordinary course of business. No proceeds of production from any Property
     prior to the Effective Time are subject to any refund as a result of the
     price paid therefor exceeding the applicable maximum lawful prices. No
     purchaser of production from any Property has placed in suspense any funds
     owing to Seller which are attributable to any period of time subsequent to
     the Effective Time.

     proceedings, other than increased density actions, actions, causes of
     action, suits or other legal proceedings pending or, to Seller's knowledge,
     threatened against Seller with respect to any of the Properties.

          (f)  Leases.  All rentals, royalties, overriding royalty interests and
               ------

     damage, liability, loss, cost, expense, attorney's fees, judgment, or
     deficiency that Seller shall pay or become obligated to pay arising out of
     or resulting from (i) an inaccuracy in any representation or the breach of
     any warranty of Buyer under this Agreement; (ii) a failure of Buyer to duly
     perform or observe any term, provision, covenant, or agreement to be
     performed or observed by Buyer hereunder; (iii) Buyer's ownership,
     management or control of the Properties after Closing; or (iv) violations
     by Buyer of any state or federal environmental laws; provided, however,
     that in no event shall Buyer have any liability for any obligation with
     respect to any tortious actions, breaches of contract or other wrongful
     acts of Seller.

          (c)  Limitations on Indemnities.  No claim or indemnity (which shall
               --------------------------                                     
     not exceed the allocated value of the affected property) shall be made
     hereunder until the amounts involved, per Property per defect and per
     occurrence, actual or alleged, exceed $20,000; and, any such claim for
     indemnity shall then be limited to the amount by which such claim exceeds
     $20,000.

          (d)  Right to Contest and Defend.  The indemnitor hereunder shall be
               ---------------------------                                    
     entitled, at its cost and expense, to contest and defend by all appropriate
     legal proceedings, any claim with respect to which it is called upon to
     indemnify the other party hereunder; provided, that notice of the intention
     to so contest shall be delivered by the indemnitor to the indemnitee within
     15 calendar days from the date indemnitor received notice of the
     indemnitee's claim.  Any such contest may be conducted in the name and on
     behalf of the indemnitor or the indemnitee as may be appropriate.  Such
     contest shall be conducted by reputable counsel employed by the indemnitor,
     but the indemnitee shall have the right to participate in such proceedings
     and to be represented by counsel of its own choosing at its sole cost and
     expense.  If the indemnitee joins in any such contest, the indemnitor shall
     have full authority to determine all action to be taken with respect
     thereto; provided, however, that the indemnitor shall not have the
     authority to subject the indemnitee to any obligation whatsoever, other
     than the performance of purely ministerial tasks (e.g., the execution of
     settlement agreements and other documentation) or obligations not involving
     significant expense.  If the indemnitor does not elect to contest any such
     claim, the indemnitor shall be bound by any judicial result obtained with
     respect thereto by the indemnitee.  Indemnitor shall not be bound by any
     settlement that it does not expressly approve.

     15.  Tax Free Exchange.  Buyer and Seller hereby agree that Seller, in lieu
          -----------------                                                     
of the sale of the Properties to Buyer for the cash consideration provided
herein, shall have the right at any time prior to Closing to assign all or a
portion of its rights under this Agreement to a qualified intermediary, in order
to accomplish the transaction in a manner that will comply, either in whole or
in part, with the requirements of a like kind exchange pursuant to (S) 1031 of
the Internal Revenue Code of 1986, as amended.  In the event Seller does assign
its rights under this Agreement pursuant to this Section, Seller agrees to
notify Buyer in writing of such assignment not less than seven (7) days before
Closing.  If Seller assigns its rights under this Agreement, Buyer agrees to (i)
consent to Seller's assignment of its rights in this Agreement, and (ii) deposit
the Purchase Price with the qualified escrow or qualified trust account at
Closing.

     16.  Maintenance of Properties.  Seller will cause the Properties to be
          -------------------------                                         
maintained and operated, from and after the date of this Agreement through
Closing, in a good and workmanlike manner; will pay or cause to be paid all
bills and invoices for all costs and expenses incurred in connection with the
development, operation and maintenance of the Properties before bills or
invoices become delinquent; and will continue to operate the Properties in the
ordinary course of business; provided, however, that Seller shall not (i) enter
into any new commitment with respect to any of the Properties which shall
require a gross expenditure of $10,000 for any single operation without the
consent of Buyer, which consent shall not be unreasonably withheld, or (ii)
waive, compromise or settle any right or claim that would adversely affect the
ownership, operation or value of any of the Properties.  Seller will use all
reasonable efforts after Closing to assist Buyer (or its designee) in being
designated operator under applicable joint operating agreements and regulatory
orders of all wells included within the Properties and Seller will allow Buyer,
or its designee, to take over operations of such wells as of 7:00 a.m., local
time, on the first day of the month following Closing.  Promptly after Closing,
Seller will exercise reasonable efforts to assist Buyer in filing any necessary
forms or applications with the appropriate regulatory authority to amend any
records or orders under which Seller is acting as operator so as to substitute
Buyer, or its designee.

     17.  Transfer Orders.  At Closing, Seller agrees to execute such transfer
          ---------------                                                     
orders, letters in lieu of transfer orders, or other documents as may be
necessary to effect payment of revenues to Buyer.

     18.  Miscellaneous.
          --------------

          (a)  Seller and Buyer shall each pay their own expenses and costs
     (including, without limitation, any and all broker's or finder's fees and
     commissions and attorney's fees) in connection with this Agreement and the
     transactions contemplated hereby, except as otherwise provided herein.

          (b)  This Agreement shall be construed in accordance with and shall be
     governed by the substantive laws of the State of Oklahoma.

          (c)  Buyer, at its option after closing, may assign all or any portion
     of its rights under this Agreement to any third party, but shall remain
     liable for Buyer's obligations hereunder unless specifically released by
     Seller. This Agreement shall be binding upon the undersigned and their
     respective successors and assigns.

          (d)  All representatives, warranties and covenants contained in this
     Agreement shall be deemed to survive Closing.

          (e)  This Agreement may be executed in any number of counterparts and
     each such signed counterpart shall constitute an original of this
     Agreement.

          (f)  All notices under this Agreement shall be in writing and shall be
     deemed given (i) when received if delivered personally, (ii) when sent if
     by facsimile transmission and a confirmation is received, (iii) one
     business day after deposit with an express courier if carried on a
     nationally recognized express courier, or (iv) two business days after
