ITEM 5.   OTHER EVENTS
- ------    ------------

     On August 15, 1997, Inland Resources Inc. (the "Company") acquired the
"Enserch Properties" from Enserch Exploration, Inc. ("Enserch") for $10.1
million in cash.  The Enserch Properties consist of 153 gross (46.9 net) oil and
gas wells, 9,600 net undeveloped acres, water rights and a water transportation
and distribution system.  The undeveloped acreage provides the Company with
approximately 240 additional drillsites in the Monument Butte Field.  The
acquisition of the Enserch Properties also included operating rights to two
approved water flood units (encompassing 42 of the wells acquired).

     Management believes that the Enserch Properties have significant
development potential which will enable the Company to increase its cash flow
from operations and reserve base at a cost efficient rate due to the proximity
of the Enserch Properties to the Company's existing properties. The Enserch
Properties are geographically concentrated in proximity to the Company's
properties in the Monument Butte Field, thereby enabling the Company to operate
the properties without incurring significant incremental general and
administrative expenses.  Of the 153 gross wells acquired, the Company already
operated 43 of the wells and Enserch operated 52 of the wells so that the
Company now operates 95 of the wells.

     The Company financed the acquisition of the Enserch Properties with a
portion of the proceeds of its existing credit facility with Canadian Imperial
Bank of Commerce.

                          PURCHASE AND SALE AGREEMENT
                          ---------------------------


          This Agreement, dated July 10, 1997, is made by and between ENSERCH
EXPLORATION, INC. ("Seller") and INLAND PRODUCTION COMPANY ("Buyer").

          1.  Property to be Sold and Purchased.  Seller agrees to sell, and
              ---------------------------------                             
Buyer agrees to purchase, for the consideration hereinafter set forth, and
subject to the terms and conditions contained herein, the following described
properties, rights, and interests:

          (a) All of Seller's right, title, and interest in and to the oil, gas,
     and mineral leases described in Exhibit "A," which is attached hereto and
     made a part hereof (and any ratifications and amendments to such leases,
     whether or not such ratifications and amendments are described in Exhibit
     "A"), and all of Seller's right, title, and interest in and to the fee
     mineral interests described in Exhibit "A," if any; and

          (b) All of Seller's right, title, and interest in and to, or otherwise
     derived from, all presently existing and valid oil, gas, and mineral
     unitization, pooling, and communitization agreements, declarations, and
     orders (including, without limitation, all units formed under orders,
     rules, regulations, or other official acts of any federal, state, or other
     governmental authority having jurisdiction, and voluntary unitization
     agreements, designations, and declarations) relating to the properties,
     rights, and interests described in Section 1.(a), to the extent such right,
     title, and interest are attributable to the properties, rights, and
     interests described in Section 1.(a); and

          (c) All of Seller's right, title, and interest in and to all presently
     existing and valid production sales contracts, operating agreements, and
     other agreements and contracts that relate to any of the properties,
     rights, and interests described in Sections 1.(a) and 1.(b), to the extent
     such right, title, and interest are attributable to the properties, rights,
     and interests described in Sections 1.(a) and 1.(b); and

          (d) All of Seller's right, title, and interest in and to all
     materials, supplies, machinery, equipment, improvements, and other personal
     property and fixtures located on the properties described in Sections 1.(a)
     and 1.(b) and used in connection with the exploration, development,
     operation, or maintenance thereof (including, but not limited to, all
     wells, wellhead equipment, pumping units, flowlines, tanks, buildings,
     injection facilities, saltwater disposal facilities, compression
     facilities, gathering systems, and other equipment).

The properties, rights, and interests described in Sections 1.(a), 1.(b), 1.(c),
and 1.(d) shall hereinafter sometimes collectively be referred to as the
"Properties."  The term "Properties" shall 

                                       1
<PAGE>
 
not include seismic data, geological or geophysical data, any interpretations
thereof, or other similar data.

     2.  Purchase Price.  The unadjusted purchase price for the Properties shall
         --------------                                                         
be Ten Million One Hundred Thousand and No/100 Dollars ($10,100,000.00), which
shall hereinafter be referred to as the "Base Purchase Price."  The Base
Purchase Price may be adjusted, as provided for hereinafter in this Section and
in Sections 6.(c) and 8. hereof.  The Base Purchase Price, as so adjusted and as
otherwise adjusted by agreement of the parties herein, shall hereinafter be
referred to as the "Purchase Price."  Buyer shall pay the Purchase Price to
Seller at Closing, as provided in Section 11. hereof.

     3.   Deposit.  Contemporaneous with its execution of this Agreement, Buyer
          -------                                                              
shall pay to Seller One Million Ten Thousand and No/100 Dollars ($1,010,000.00),
which shall hereinafter be referred to as the "Deposit."  If Buyer and Seller
consummate the transaction contemplated by this Agreement, the Deposit shall be
applied to the Purchase Price.  If Buyer and Seller do not consummate the
transaction contemplated by this Agreement because of a material default by
Seller in the absence of a default by Buyer, Seller shall return the Deposit to
Buyer.  If Buyer and Seller terminate this Agreement pursuant to Section 9. or
Section 10. hereof under circumstances where such Section requires the return of
the Deposit, then Seller shall return the Deposit to Buyer.  Except as provided
in the preceding sentence, if Buyer fails or refuses to consummate the
transaction contemplated by this Agreement, or if the transaction contemplated
by this Agreement otherwise fails to close on the Closing Date, Seller shall
retain the Deposit as liquidated damages.  The parties agree that damages in
such an event would be extremely difficult to determine, that the Deposit
represents a fair and reasonable estimate of such damages under the
circumstances, and that such a retention of the Deposit does not constitute a
penalty.

     4.   Seller's Representations.  Seller represents to Buyer that:
          ------------------------                                   

          (a) Seller is a corporation duly organized and legally existing under
     the laws of its state of incorporation. Seller is qualified to do business
     and is in good standing, or will be at Closing, in each state in which
     Properties are located where the laws of such state require a corporation
     owning the Properties located in such state to qualify to do business.

          (b) Seller has full power to enter this Agreement and perform its
     obligations hereunder and has taken all proper action to enter this
     Agreement and perform its obligations hereunder.

          (c) Seller's execution and delivery of this Agreement, the
     consummation of the transaction contemplated hereby, and Seller's
     compliance with the terms hereof, will not result in a default under any
     agreement or instrument to which Seller is a party or by which the
     Properties are bound that would be material to the transaction contemplated
     hereby.  Seller's execution and delivery of this Agreement will not violate
     any order, writ, 

                                       2

     injunction, decree, statute, rule, or regulation applicable to Seller or to
     the Properties that would be material to the transaction contemplated
     hereby, except the following:

               (i) Any consents to transfer or waivers of preferential rights to
          purchase that must be obtained from third parties;

               (ii) Compliance with the Hart-Scott-Rodino Antitrust Improvements
          Act of 1976 (the "Hart-Scott-Rodino Act");

          the lessor under a lease included in the Properties (or that
          administers such lease for such lessor) and that is customarily
          obtained post-closing; and

               (iv) Any maintenance of uniform interest provision contained in
          any operating agreement or other agreement.

          (d) This Agreement constitutes the legal, valid, and binding
     obligation of Seller, enforceable according to its terms, except as limited
     by bankruptcy or other laws applicable generally to creditor's rights and
     as limited by general equitable principles.  The Assignment and Bill of
     Sale provided for in Section 11.(a)(i) hereof, and any other documentation
     provided for herein to be executed by Seller, will, when executed and
     delivered, constitute the legal, valid, and binding obligations of Seller,
     enforceable according to their terms, except as limited by bankruptcy or
     other laws applicable generally to creditor's rights and as limited by
     general equitable principles.

          (e) Except as disclosed on Exhibit "D," there are no pending suits,
     actions, or other proceedings filed by parties other than Seller, and to
     which Seller is a party, that materially affect the Properties (including,
     without limitation, any actions challenging or pertaining to Seller's title
     to any of the Properties) or that affect the execution and delivery of this
     Agreement or the consummation of the transaction contemplated hereby.

     5.   Buyer's Representations.  Buyer represents to Seller that:
          -----------------------                                   

          (a) Buyer is a corporation duly organized and legally existing under
     the laws of its state of organization.  Buyer is qualified to do business

     Properties are located where the laws of such state require a corporation
     owning the Properties located in such state to qualify to do business.

          (b) Buyer has full power to enter this Agreement and perform its
     obligations hereunder and has taken all proper action to enter this
     Agreement and perform its obligations hereunder.

<PAGE>
 
          (c) Buyer's execution and delivery of this Agreement, the consummation
     of the transaction contemplated hereby, and Buyer's compliance with the
     terms hereof, will not result in a default under any agreement or
     instrument to which Buyer is a party or by which the Properties are bound
     that would be material to the transaction contemplated hereby.  Buyer's
     execution and delivery of this Agreement will not violate any order, writ,
     injunction, decree, statute, rule, or regulation applicable to Buyer or to
     the Properties that would be material to the transaction contemplated
     hereby, except the following:

               (i) Any consents to transfer or waivers of preferential rights to
          purchase that must be obtained from third parties;

               (ii) Compliance with the Hart-Scott-Rodino Act;

               (iii)  Any approval required from a governmental entity that is

          administers such lease for such lessor) and that is customarily
          obtained post-closing; and

               (iv) Any maintenance of uniform interest provision contained in
          any operating agreement or other agreement.

          (d) This Agreement constitutes the legal, valid, and binding
     obligation of Buyer, enforceable according to its terms, except as limited
     by bankruptcy or other laws applicable generally to creditor's rights and
     as limited by general equitable principles.  The Assignment and Bill of
     Sale provided for in Section 11.(a)(i) hereof and any other documentation
     provided for herein to be executed by Buyer, will, when executed and
     delivered, constitute the legal, valid, and binding obligations of Buyer,
     enforceable according to their terms, except as limited by bankruptcy or
     other laws applicable generally to creditor's rights and as limited by
     general equitable principles.
          (e) There are no pending suits, actions, or other proceedings filed by
     parties other than Buyer, and to which Buyer is a party, that materially
     affect the execution and delivery of this Agreement or the consummation of
     the transaction contemplated hereby.

          (f) Buyer is a knowledgeable purchaser, owner, and operator of oil and
     gas properties, has the ability to evaluate, and has evaluated, the
     Properties for purchase, and is acquiring the Properties for its own
     account and not with the intent to make a distribution within the meaning
     of the Securities Act of 1933, as amended (and the rules and regulations
     pertaining thereto), or a distribution thereof in violation of any other
     applicable securities laws, rules, or regulations.

          (g) With regard to those Properties that Buyer seeks to operate, Buyer
     is qualified to operate such Properties under the applicable laws, rules,
     and regulations of the jurisdiction in which such Properties are located,
     or will become so qualified before operating such Properties.

     6.   Covenants of Seller and Buyer Pending Closing.  Between the date of
          ---------------------------------------------                      
this Agreement and the Closing Date:

          (a) Seller shall permit Buyer access to the Properties as follows:

               (i) Seller shall give Buyer access at all reasonable times during
          normal business hours to the Properties and, at Seller's office, to
          Seller's records pertaining to the ownership and operation of the
          Properties (including, without limitation, title files; division order
          files; well files; production records; equipment inventories; and
          production, severance, and ad valorem tax records).  Buyer may make
          copies of such records at its expense.  If the Closing does not occur,
          Buyer shall return all such copies to Seller.  Seller shall not be
          obligated to provide Buyer with access to any records or data that
          Seller considers to be proprietary or confidential or that Seller
          cannot provide to Buyer without, in Seller's opinion, breaching, or
          risking a breach of, confidentiality agreements with other parties.
          Any records or data provided hereunder shall be subject to any
          confidentiality agreement entered between Buyer and Seller in
          contemplation of this Agreement.  Seller makes no representation or
          warranty of any kind as to the accuracy or completeness of any
          materials made available to Buyer in connection with the transaction
          contemplated hereby.

               (ii) Seller shall make a good faith effort to give Buyer, at
          reasonable times, and upon adequate notice to Seller, physical access
          to inspect the Properties.  Buyer recognizes that some or all of the
          Properties may be operated by parties other than Seller and that
          Seller's ability to obtain access to such Properties, and the manner
          and extent of such access, may be subject to the consent of such third
          parties.  While Buyer is upon, entering, or leaving the Properties, it
          agrees to comply fully with the rules, regulations, and instructions
          issued by Seller and, where any portion of the Properties are operated
          by other parties, such third parties.

               (iii)  Exculpation and Indemnification.  If Buyer exercises
                      -------------------------------                     
          rights of access under this Section, or otherwise, or conducts
          examinations or inspections under this Section, or otherwise, then (a)
          such access, examination, and inspection shall be at Buyer's sole
          risk, cost, and expense, and Buyer waives and releases all claims
          against Seller (its affiliates and their respective directors,
          officers, employees, attorneys, contractors, and agents) arising in
          any way therefrom or in any way connected therewith or arising in
          connection with the conduct of its directors, officers, employees,
          attorneys, contractors, and agents in connection therewith; and (b)
          BUYER SHALL RELEASE, INDEMNIFY, DEFEND, AND HOLD HARMLESS SELLER, AND
          ITS PARENT OR SUBSIDIARY COMPANIES AND OTHER AFFILIATES, AND THEIR
          RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS, CONTRACTORS, 

                                       5

          GROUP"), FROM ANY AND ALL CLAIMS, ACTIONS, CAUSES OF ACTION,
          LIABILITIES, DAMAGES, LOSSES, COSTS, OR EXPENSES (INCLUDING, WITHOUT

          FOR LABOR OR MATERIALS ARISING OUT OF OR IN ANY WAY CONNECTED WITH
          SUCH ACCESS, EXAMINATIONS, OR INSPECTIONS. THE FOREGOING RELEASE AND
          INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH CLAIMS, ACTIONS,
          CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS, OR EXPENSES
          ARISE OUT OF (I) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE
          NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE NEGLIGENCE, OR PASSIVE
          NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE OR WILLFUL
          MISCONDUCT) OF SELLER OR ANY OTHER INDEMNIFIED PARTY, OR (II) STRICT
          LIABILITY.

          (b) Until the Closing Date, Seller shall continue to operate in the
     ordinary course of its business any portion of the Properties over which it
     serves as operator and to manage in the ordinary course of its business any
     portion of the Properties over which it does not serve as operator.  Except
     as set forth in this Agreement, Seller shall not sell or otherwise dispose
     of any material portion of the Properties.  If Seller receives or desires
     to make a proposal to drill a well on the Properties or to conduct other
     operations on the Properties that require the consent of non-operators
     under any applicable operating agreement, it shall notify Buyer thereof and
     shall consult with Buyer concerning such proposal.  However, Seller shall
     make its decision regarding such proposal in its own discretion and in the
     ordinary course of its business.

          (c) Seller shall use reasonable efforts, consistent with industry
     practices in transactions of this type, to identify, with respect to each
     material portion of the Properties, all preferential rights to purchase and
     all rights of third parties to withhold consent to a transfer that would
     apply to the transaction contemplated hereby and the parties holding such
     rights.  In attempting to identify the same, Seller shall not be obligated
     to go beyond its own records.  Seller shall request from the parties so
     identified (and in accordance with the documents creating such rights)
     waivers of the preferential rights to purchase and consents to transfer so
     identified.  Seller shall have no obligation hereunder other than to
     attempt to identify such preferential rights and rights to withhold consent
     to transfer and to request such waivers and consents.  Seller shall not be
     obligated to assure that such waivers and consents are obtained. Seller may
     tender to any party refusing to waive such a preferential right the
     interest covered by such right at a price equal to the amount specified in
     Exhibit "B" for such interest. To the extent that such an interest actually
     is transferred to a party exercising such a preferential right, it shall be
     excluded from the transaction contemplated hereby, and the Base Purchase
     Price shall be

                                       6
<PAGE>
 
     reduced by the amount such party paid to Seller for such interest, unless
     the parties hereto agree otherwise.

          (d) If applicable, as soon as practicable after the execution hereof,
     Buyer shall prepare and submit any filing required under the Hart-Scott-
     Rodino Act in connection with the transaction contemplated by this
     Agreement.  Buyer shall pay all filing fees in connection with such filing,
     shall request expedited treatment of such filing by the Federal Trade
     Commission ("FTC"), shall make any appropriate or necessary subsequent or
     supplemental filings, and shall furnish to Seller copies of all filings
     made under the Hart-Scott-Rodino Act at the same time they are filed with
     the FTC.  Seller shall cooperate with Buyer as to all filings required by
     the Hart-Scott-Rodino Act.

     7.   Due Diligence Reviews.
          --------------------- 

          (a) The term "Defect," as used in this Section, shall mean the
     following:

               (i) Seller's ownership of a well, unit, or undeveloped tract
          listed on Exhibit "B" (A) entitles Seller to receive a share of the
          oil, gas, and other hydrocarbons produced from, or allocated to, such
          well, unit, or undeveloped tract that is less than the share set forth
          on Exhibit "B" for such well, unit, or undeveloped tract in the column
          headed "Net Revenue Interest," or (B) causes Seller to bear a share of
          the cost of operating such well, unit, or undeveloped tract greater
          than the share set forth on Exhibit "B" for such well, unit, or
          undeveloped tract in the column headed "Operating Interest" (without a
          proportionate increase in the share of production to which Seller is
          entitled from such well, unit, or undeveloped tract); or

               (ii) Seller's ownership of the Properties is subject to a lien
          other than (A) a lien that will be released at or before Closing, (B)
          a lien for taxes not yet delinquent, (C) a mechanic's or materialmen's
          lien (or other similar lien), or (D) a lien under an operating
          agreement or similar agreement, to the extent the same relates to
          expenses incurred that are not yet due; or

               (iii)  Seller's ownership of the Properties is subject to a
          preferential right to purchase, unless the party holding such right
          has waived it for the transaction contemplated hereby or has not
          exercised it within the required period of time; or

               (iv) Seller's ownership of the Properties is subject to an
          imperfection in title that, if asserted, would cause a Defect, as
          defined in Section 7.(a)(i) hereof, to exist and such imperfection in
          title normally would not be waived by persons engaged in the oil and
          gas business purchasing producing property; or

                                       7
<PAGE>
 
               (v) The Properties are in violation of Applicable Environmental
          Laws (as hereinafter defined) in any material respect, unless such
          violation is disclosed on Exhibit "D."  "Applicable Environmental
          Laws" shall mean all federal, state, or local laws, rules, orders, or
          regulations in effect on the Effective Date of this Agreement
          pertaining to health or the environment, including those relating to
          waste materials and hazardous substances.

          (b) A gas imbalance does not constitute a Defect and shall be subject
     to the provisions of Section 12. hereof.

          (c) Buyer may conduct such examinations and investigations, at its
     sole cost, that it deems are appropriate to determine whether Defects
     exist.  Buyer shall notify Seller, in writing, of each Defect that Buyer is
     unwilling to waive hereunder (an "Asserted Defect") as soon as Buyer
     identifies such Defect, but no later than ten (10) days prior to the date
     upon which Closing is scheduled to occur pursuant to Section 11., but not
     as extended pursuant to 11.(i) or 11.(ii) (hereinafter the "Defect Notice
     Date").  Such notification shall include:  (i) a description of the
     Asserted Defect, the lease or mineral interest described in Exhibit "A"
     that such Asserted Defect affects, the wells, units, and undeveloped tracts
     listed on Exhibit "B" to which the Asserted Defect relates, and all
     supporting documentation reasonably necessary fully to describe the basis
     for the Asserted Defect; (ii) for each applicable well, unit, or
     undeveloped tract, the size of any variance from the "Net Revenue Interest"
     or "Operating Interest" set forth in Exhibit "B" that does or could result
     from such Asserted Defect; and (iii) the amount by which Buyer proposes to
     adjust the Purchase Price because of such Asserted Defect.  Buyer hereby
     waives all Defects that it fails to identify to Seller as Asserted Defects
     on or before the Defect Notice Date.  If Buyer notifies Seller of Asserted
     Defects, Seller (i) shall have the right (but not the obligation) to
     attempt to cure such Asserted Defects prior to Closing, and (ii) shall have
     the right (which may be exercised at any time before the Closing Date) to
     postpone the Closing by designating a new Closing Date not later than
     thirty (30) days after the Closing Date then existing in order to attempt
     to cure, or to determine if it will attempt to cure, one or more Asserted
     Defects.  In lieu of curing or attempting to cure an Asserted Defect,
     Seller may elect, at any time prior to Closing, to indemnify and hold Buyer
     harmless from and against any actual damages or loss (but specifically
     excluding consequential, special, or similar damages) Buyer may suffer as a
     result of a third-party claim based on such Asserted Defect.  Each such
     Asserted Defect shall be treated under this Agreement as cured.

          (d) Buyer shall have the right to make an environmental assessment of
     the Properties during the period beginning on the date this Agreement is
     fully executed and ending on the Defect Notice Date.  Buyer and its agents
     shall have the right to enter upon the Properties and all buildings and
     improvements thereon, inspect the same, conduct soil and water tests and
     borings, and generally conduct such tests, examinations, investigations,
     and studies as may be necessary or appropriate for the preparation of

                                       8
<PAGE>
 
     appropriate engineering and other reports in relation to the Properties,
     their condition, and the presence of Hazardous Substances (as the term
     "Hazardous Substance" is defined in the Comprehensive Environmental
     Response, Compensation and Liability Act, 42 U.S.C. Sec. 9601, et seq).
     Buyer agrees to provide Seller with a copy of the environmental assessment
     promptly upon Buyer's completion thereof, including any reports, data, and
     conclusions.  Buyer shall keep any data or information acquired by such
     examinations and the results of all analyses of such data and information
     strictly confidential and shall not disclose same to any person or agency
     without the prior written approval of Seller.  BUYER SHALL RELEASE,
     INDEMNIFY, DEFEND, AND HOLD HARMLESS THE SELLER GROUP FROM AND AGAINST ANY
     AND ALL LOSS, COST, DAMAGE, EXPENSE, OR LIABILITY WHATSOEVER, INCLUDING
     ATTORNEYS' FEES, ARISING OUT OF ANY INJURY TO OR DEATH OF PERSONS OR DAMAGE
     TO PROPERTY OCCURRING IN, ON, OR ABOUT THE PROPERTIES AS A RESULT OF SUCH
     ENVIRONMENTAL ASSESSMENT (EXCEPT ANY SUCH INJURIES OR DAMAGES CAUSED SOLELY
     BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY MEMBER OF THE SELLER
     GROUP).  After the Defect Notice Date, Buyer shall be deemed to have
     inspected the Properties or waived its right to inspect the Properties for
     all purposes and satisfied itself as to their physical and environmental
     condition, both surface and subsurface, including, but not limited to,
     conditions specifically related to the presence, release, or disposal of
     Hazardous Substances.

     8.   Price Adjustments.
          ----------------- 

          (a) If Buyer presents Asserted Defects to Seller as part of the due
     diligence reviews provided for in Section 7., and if Seller is unable or
     unwilling to cure all such Asserted Defects prior to Closing, or if Buyer
     has elected to treat a portion of the Properties affected by a casualty
     loss pursuant to Section 16. as if it were affected by an Asserted Defect,
     then:

               (i) Buyer and Seller shall, with respect to each portion of the
          Properties affected by such matters, attempt to agree upon an
          appropriate amount by which the Base Purchase Price should be
          decreased; and

               (ii) For each such portion of the Properties on which Buyer and
          Seller are unable to agree upon an amount by which the Base Purchase
          Price should be decreased, the amount of such decrease shall be the
          amount attributed on Exhibit "B" to such portion of the Properties.

          (b) Buyer shall disclose to Seller circumstances discovered by Buyer
     in the due diligence review provided for in Section 7. hereof that could
     result in an increase in the Purchase Price hereunder.  If Seller is shown
     to be entitled to a share of production from 

                                       9
<PAGE>
 
     a well or unit listed on Exhibit "B" greater than the share shown for such
     well or unit under the column headed "Net Revenue Interest" on Exhibit "B,"
     then:

               (i) Buyer and Seller shall, with respect to each portion of the
          Properties affected thereby, attempt to agree upon an appropriate
          amount by which the Base Purchase Price should be increased; and

               (ii) For each such portion of the Properties on which Buyer and
          Seller are unable to agree upon an amount by which the Base Purchase
          Price should be increased, the amount of such increase shall be the
          difference between the amount attributed on Exhibit "B" to the wells
          located on such portion of the Properties and the units in which such
          portion of the Properties participates (or, as applicable, the
          undeveloped tract located on such portion of the Properties) and a
          fraction times the amount attributed on Exhibit "B" to the wells
          located on such portion of the Properties and the units in which such
          portion of the Properties participates (or, as applicable, the
          undeveloped tract located on such portion of the Properties), the
          numerator of which fraction shall be the net revenue interest for such
          well or unit (or, as applicable, the undeveloped tract located on such
          portion of the Properties) to which Seller actually is shown to be
          entitled and the denominator of which fraction shall be the share
          shown for such well or unit (or, as applicable, the undeveloped tract
          located on such portion of the Properties) under the column headed
          "Net Revenue Interest" on Exhibit "B."

          (c) If the total amount by which the Base Purchase Price is to be
     decreased under Section 8.(a) for all Properties, when subtracted from the
     total amount by which the Base Purchase Price is to be increased under
     Section 8.(b) for all Properties, equals more than four percent (4%) of the
     Base Purchase Price, the portion of the Properties affected by a decrease
     under Section 8.(a) shall be excluded from the transaction contemplated
     hereby, and the Purchase Price hereunder shall equal the Base Purchase
     Price minus the amount by which such decrease exceeds four percent (4%) of
     the Base Purchase Price.  If the total amount by which the Base Purchase
     Price should be decreased under Section 8.(a) for all Properties, when
     subtracted from the total amount by which the Base Purchase Price should be
     increased under Section 8.(b) for all Properties, equals four percent (4%)
     or less of the Base Purchase Price, the portion of the Properties affected
     by a decrease under Section 8.(a) shall not be excluded from the
     transaction contemplated hereby, and the Base Purchase Price shall not be
     adjusted hereunder. If the total amount by which the Base Purchase Price
     should be increased under Section 8.(b) for all Properties, after
     subtracting the total amount by which the Base Purchase Price should be
     decreased under Section 8.(a) for all Properties, equals more than four
     percent (4%) of the Base Purchase Price, the Purchase Price hereunder shall
     equal the Base Purchase Price plus the amount by which such increase
     exceeds four percent (4%) of the Base Purchase Price. If the total amount
     by which the Base Purchase Price should be increased under Section 8.(b)
     for all Properties, after subtracting the total amount by which the Base
     Purchase Price should be 

                                      10
<PAGE>
 
     decreased under Section 8.(a) for all Properties, equals four percent (4%)
     or less of the Base Purchase Price, the Base Purchase Price shall not be
     adjusted hereunder.

     9.   Conditions Precedent to Buyer's Obligations.  Buyer's obligations
          -------------------------------------------                      
under this Agreement are subject to each of the following conditions:

          (a) Seller's representations under this Agreement shall be true and
     accurate in all material respects as of the date when made and at Closing.
     At Closing, Seller's representations under this Agreement shall be true and
     accurate in all material respects except as to changes specifically
     contemplated by this Agreement or consented to by Buyer.

          (b) Seller shall have performed and complied in all material respects
     with every covenant, agreement, and condition required by it under this
     Agreement prior to or at the Closing unless performance or compliance
     therewith shall have been waived by Buyer.

          (c) If applicable, Buyer and Seller shall have received approval of
     the transaction contemplated by this Agreement from the FTC under the Hart-
     Scott-Rodino Act, or shall have received notification that the waiting
     period under the Hart-Scott-Rodino Act has terminated, or the waiting
     period under the Hart-Scott-Rodino Act shall have expired.
 
          (d) The Purchase Price increase resulting from the procedure set forth
     in Section 8. does not exceed five percent (5%) of the Base Purchase Price.

          (e) On the Closing Date, no material suit, action, or other proceeding
     seeking to restrain or prohibit the consummation of the transaction
     contemplated by this Agreement or to obtain damages or other relief in
     connection therewith shall be pending against Buyer before any court or
     governmental agency.

If any such condition precedent to the obligations of Buyer under this Agreement
is not met as of the Closing Date, and if Buyer is not in material breach of its
obligations hereunder, Buyer may terminate this Agreement by giving written
notice thereof to Seller.  If Buyer thus terminates this Agreement, Seller shall
return the Deposit to Buyer, and the parties shall have no further obligations
to one another hereunder, other than the obligations under Sections 6.(a)(iii)
and 15. hereof and the confidentiality obligations under Section 7.(d) hereof,
which shall survive such termination. Notwithstanding the foregoing, if a
condition in Section 9.(a), 9.(b), or 9.(e) is not met and is asserted by Buyer
as a failure of one of its conditions of Closing, and if the reasons such
condition is not met relate only to a portion, but not all, of the Properties,
failure of such condition to be met may, at the option of either Buyer or
Seller, be treated as an uncured Asserted Defect and handled in accordance with
the procedure set forth in Section 8. hereof.

                                      11
<PAGE>
 
     10.  Conditions Precedent to Seller's Obligations.  Seller's obligations
          --------------------------------------------                       
under this Agreement are subject to the each of the following conditions:

          (a) Buyer's representations under this Agreement shall be true and
     accurate in all material respects as of the date when made and at Closing.
     At Closing, Buyer's representations under this Agreement shall be true and
     accurate in all material respects except as to changes specifically
     contemplated by this Agreement or consented to by Seller.

          (b) Buyer shall have performed and complied in all material respects
     with every covenant, agreement, and condition required by it under this
     Agreement prior to or at the Closing unless compliance therewith shall have
     been waived by Seller.

          (c) If applicable, Buyer and Seller shall have received approval of
     the transaction contemplated by this Agreement from the FTC under the Hart-

     period under the Hart-Scott-Rodino Act shall have expired.

          (d) The Purchase Price reduction resulting from the procedure set
     forth in Section 8. hereof does not exceed five percent (5%) of the Base
     Purchase Price.

          (e) On the Closing Date, no material suit, action, or other proceeding
     seeking to restrain or prohibit the consummation of the transaction
     contemplated by this Agreement or to obtain damages or other relief in
     connection therewith shall be pending against Seller before any court or
     governmental agency.

If any such condition precedent to the obligations of Seller under this
Agreement is not met as of the Closing Date, Seller may terminate this Agreement
by giving written notice thereof to Buyer.  If Seller terminates this Agreement
because of Buyer's failure to fulfill a condition in Section 10.(a) or 10.(b),
Seller shall not return the Deposit to Buyer.  If Seller terminates this
Agreement because a condition in Section 10.(c), 10.(d), or 10.(e) is not met,
and if Buyer is not in material default under this Agreement, Seller shall
return the deposit to Buyer. Thereafter, Seller and Buyer shall have no further
obligations to one another hereunder, other than the obligations under Sections
6.(a)(iii) and 15. hereof and the confidentiality obligations under Section
7.(d) hereof, which shall survive such termination.

     11.  The Closing.  The consummation of the transaction contemplated hereby
          -----------                                                          
(the "Closing") shall take place in the offices of Seller, at 6688 North Central
Expressway, Dallas, Texas 75206, on August 15, 1997, at 10:00 a.m. Central Time,
or at such other date and time (i) as Buyer and Seller may agree or (ii) to
which Seller may postpone the Closing pursuant to Section 7. hereof (such date
and time, as changed pursuant to clauses (i) and (ii) being herein called the
"Closing Date").

                                      12
<PAGE>
 
          (a)  At the Closing, Seller shall:

               (i) execute, acknowledge, and deliver to Buyer a conveyance of
          the Properties (the "Assignment and Bill of Sale"), in the form
          attached hereto as Exhibit "C" (with Exhibit "A" hereto being attached
          thereto, subject to any changes made hereunder), effective as to runs
          of oil and deliveries of gas as of 7:00 a.m., local time at the
          locations of the Properties, respectively, on March 31, 1997 (herein
          called the "Effective Date"); and

               (ii) execute (and, where required, acknowledge) and deliver to
          Buyer forms of conveyance or assignment as required by the applicable
          authorities for transfers of interests in state or federal leases
          included in the Properties;

               (iii)  if Buyer requests, execute and deliver to Buyer letters in
          lieu of transfer orders (or similar documentation), in form acceptable
          to both parties; and

               (iv) if Buyer requests, deliver to Buyer an affidavit or other
          certification (as permitted by the Internal Revenue Code of 1986, as
          amended) that Seller is not a "foreign person" within the meaning of
          Section 1445 (or similar provisions) of such code (i.e., Seller is not
          a non-resident alien, foreign corporation, foreign partnership,
          foreign trust, or foreign estate, as those terms are defined in such
          code and regulations promulgated thereunder); and

               (v) to the extent Seller is able to do so, turn over possession
          of the Properties to Buyer.

          (b)  At the Closing, Buyer shall:

               (i) deliver to Seller, by wire transfer to an account designated
          by Seller in a bank located in the United States, an amount equal to
          (A) the Purchase Price, less (B) the Deposit, less (or plus, as the
          case may be) (C) any adjustments made at Closing under Section 12.
          hereof; and

               (ii) with respect to Properties operated by Seller, and subject
          to applicable operating agreement requirements, execute and deliver to
          Seller appropriate evidence reflecting change of operator as required
          by applicable authorities, and such evidence as Seller may require
          that Buyer is qualified with such authorities to succeed Seller as
          operator; and

               (iii)  execute such forms and take such other steps as Seller
          reasonably may require to (i) succeed Seller with respect to the
          Properties under the rules and regulations of applicable authorities
          and (ii) assume any plugging liabilities of Seller with respect to the
          wells located on the Properties or on units in which the 

                                      13
<PAGE>
 
          Properties participate (including, without limitation, compliance with
          state statutes).

          (c) Within fifteen (15) days after Closing, Seller shall deliver to
     Buyer all of Seller's lease files, abstracts and title opinions, division
     order files, production records, well files, copies of accounting records
     (but not including general financial accounting or tax accounting records),
     and other similar files and records that directly relate to the Properties.
     Notwithstanding the foregoing, Seller shall not be required to deliver to
     Buyer materials that Seller considers  proprietary or confidential or that
     Seller legally cannot provide to Buyer without, in its opinion, breaching,
     or risking a breach of, confidentiality agreements with other parties.  It
     is expressly understood that Buyer is not acquiring, and Seller is not
     obligated to transfer to Buyer, any seismic data, geological or geophysical
     data, or other similar data, or any interpretations thereof or other data
     or records related thereto.  With respect to each portion of the Properties
     from which Seller is disbursing proceeds of production attributable to
     other parties:

               (i) Seller shall continue to collect proceeds of production
          through the production month that includes the Closing Date and shall
          be responsible for making disbursements, in accordance with its normal
          procedures (and at normal times), of such proceeds of production so
          collected to the parties entitled to same, with any proceeds of
          production thereafter collected by Seller to be forwarded promptly to
          Buyer (who shall thereafter account for same to the parties entitled
          thereto), and

               (ii) After execution of this Agreement, Seller shall deliver to
          Buyer (A) a copy of its "pay list" for each such portion of the
          Properties (which pay list shall include the name, address, social
          security number, and applicable share of proceeds of production, to
          the extent such information is contained in Seller's records, for each
          party to whom Seller is disbursing proceeds of production with respect
          to such portion of the Properties), and (B) a list of all parties for
          whom it is holding in suspense proceeds of production.

          (d) Following delivery of the materials referred to in Section
     11.(c)(ii) hereof, Buyer shall become responsible for all disbursements of
     proceeds of production commencing with the production month after the month
     that includes the Closing Date, and such disbursement activities shall be
     included in the matters that Buyer assumes and with respect to which Buyer
     indemnifies Seller under Section 13. hereof.  It is understood and agreed
     that Seller does not represent or warrant to Buyer the accuracy of the "pay
     lists" so delivered.

          (e) SELLER GIVES NO ASSURANCE THAT BUYER SHALL SUCCEED SELLER AS
     OPERATOR OF ANY PORTION OF THE PROPERTIES IN WHICH A PARTY OTHER THAN
     SELLER OWNS AN INTEREST.  On any portion of the 

                                      14
<PAGE>
 
     Properties where Buyer shall succeed Seller as operator, Buyer and Seller
     shall cooperate during the transitional period between Seller's
     relinquishment of such operations and Buyer's assumption of such
     operations. To the extent Seller remains an operator after Closing (which
     it shall have no obligation to do), it shall serve as operator under the
     applicable operating agreement in the manner provided by such agreement
     and, to the extent Seller so operates any portion of the Properties after
     Closing, its obligations to Buyer with respect to such operations shall be
     no greater than those it would have to a non-operator under the applicable
     operating agreement (and, in the absence of an operating agreement, under
     the AAPL 610 (1989 Revision) form operating agreement). THE PARTIES
     RECOGNIZE THAT UNDER SUCH AGREEMENTS AND SUCH FORM OF AGREEMENT THE
     OPERATOR IS NOT RESPONSIBLE TO THE OTHER PARTIES THERETO FOR ITS OWN
     NEGLIGENCE AND HAS NO RESPONSIBILITY TO SUCH OTHER PARTIES OTHER THAN FOR
     GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

     12.  Accounting Adjustments.
          ---------------------- 

          (a) Appropriate adjustments shall be made between Buyer and Seller so
     that:

               (i) all expenses (including, without limitation, all drilling
          costs, all capital expenditures, and all overhead charges under
          applicable operating agreements, regardless of whether such operating
          agreements are with third parties or related entities, and regardless
          of whether Seller is the operator or a non-operator) and all other
          overhead charges actually charged by third parties and incurred in the
          operation of the Properties after the Effective Date shall be
          allocated to Buyer, and all proceeds (net of applicable production,
          severance, and similar taxes) from the sale of oil, gas, and other
          minerals produced from the Properties after the Effective Date shall
          be allocated to Buyer; and

               (ii) all expenses (including, without limitation, drilling costs,
          capital expenditures, overhead charges under applicable operating
          agreements, regardless of whether such operating agreements are with
          third parties or related entities, and regardless of whether Seller is
          the operator or a non-operator) and all other overhead charges
          actually charged by third parties and incurred in the operation of the
          Properties before the Effective Date shall be allocated to Seller, and
          all proceeds (net of applicable production, severance, and similar
          taxes) from the sale of oil, gas, and other minerals produced from the
          Properties before the Effective Date shall be allocated to Seller.

     (b) In making such adjustments, the parties agree that:

               (i) oil above pipeline connections that was produced from the
          Properties and that was stored in tanks located on the Properties on
          the Effective Date (or 

                                      15
<PAGE>
 
          located elsewhere but used by Seller to store oil produced from the
          Properties prior to delivery to oil purchasers) shall be deemed to
          have been produced before the Effective Date; and

               (ii) ad valorem and similar taxes assessed for periods prior to
          the Effective Date shall be borne by Seller, and ad valorem taxes
          assessed for periods on or after the Effective Date shall be borne by
          Buyer (ad valorem and similar taxes shall be considered assessed for
          the period for which they are stated to be assessed, even if the same
          are based on production or other activities occurring in prior
          periods); and

               (iii) ad valorem taxes with respect to the period containing
          the Effective Date shall be prorated between Buyer and Seller based on
          the number of days in such period that fall before and after the
          Effective Date (with the Effective Date being counted in the period
          after the Effective Date); and

               (iv) no consideration shall be given to the local, state, or
          federal income tax liabilities of any party.

          (c) In addition, Buyer and Seller shall determine (i) the total amount
     of overproduction of gas (measured in Mcf) with respect to the Properties
     as of the Effective Date (e.g. volumes of gas taken from wells on the
     Properties, or on lands unitized therewith, by the owners of the Properties
     in excess of those volumes that the ownership of the Properties would
     entitle such owners to receive) and (ii) total amount of underproduction of
     gas (measured in Mcf) with respect to the Properties as of the Effective
     Date (e.g. the amount by which the volume of gas from wells on the
     Properties, or on lands unitized therewith, that the ownership of the
     Properties would entitle the owners thereof to take exceeds the volumes
     taken from such wells by owners). If the total amount of overproduction
     exceeds the total amount of underproduction, Buyer shall be credited with
     an amount equal to $1.00 times such excess. If the total amount of
     underproduction exceeds the total amount of overproduction, Seller shall be
     credited with an amount equal to $1.00 times such excess. Buyer and Seller
     also shall determine the amount of all pipeline and gathering system
     imbalances that existed as of the Effective Date with respect to deliveries
     from the Properties. Seller shall receive credit for all benefits arising
     out of such imbalances, and Buyer shall receive credit for all obligations
     arising out of such imbalances.

          (d) At or before Closing, the parties shall determine, based upon the
     best information reasonably available to them (and as to adjustments under
     Section 12.(a), based on amounts actually received or paid by Seller prior
     to such time), the amount of the adjustments provided for in Sections
     12.(a) and 12.(b).  If the amount of such adjustments resulting in a credit
     to Buyer exceeds the amount of such adjustments resulting in a credit to
     Seller, Buyer shall receive a credit for the amount of such excess.  If the

                                      16
<PAGE>
 
     amount of such adjustments resulting in a credit to Seller exceeds the
     amount of such adjustments resulting in a credit to Buyer, Buyer shall pay
     to Seller the amount of such excess.  On or before one hundred twenty (120)
     days after Closing, Buyer and Seller shall review any additional
     information pertaining to the adjustments provided for in Sections 12.(a)
     and 12.(b), shall determine if any additional adjustments should be made
     beyond those made at Closing (whether the same be made to account for
     expenses or revenues, or overproduction or underproduction volumes, not
     considered in making the adjustments made at Closing, or to correct errors
     made in such adjustments), and shall make any such adjustments by
     appropriate payments from Seller to Buyer or from Buyer to Seller.
     Following such additional adjustments, no further adjustments shall be made
     under this Agreement.

     13.  Assumption and Indemnification.  On the date of Closing, Buyer shall
          ------------------------------                                      
agree (and, upon the delivery to Buyer of the Assignment and Bill of Sale shall
be deemed to have agreed):  (a) to assume, pay, and perform timely all duties,
obligations, and liabilities relating to the ownership or operation of the
Properties after the Effective Date (including, without limitation, those
arising under the contracts and agreements described in Section 1.(c) hereof),
and (b) to release, indemnify, defend, and hold harmless the Seller Group from
and against any and all claims, actions, liabilities, losses, damages, costs, or
expenses (including court costs and attorneys' fees) of any kind or character
arising out of or otherwise relating to the ownership or operation of the
Properties after the Effective Date.  In connection with (but not in limitation
of) the foregoing, it is specifically understood and agreed that matters arising
out of or otherwise relating to the ownership or operation of the Properties
after the Effective Date shall be deemed to include all matters arising out of
the condition of the Properties on the Effective Date including, without
limitation, all obligations properly to plug and abandon wells located on the
Properties, to restore the surface of the Properties, and to comply with, or to
bring the Properties into compliance with, applicable environmental laws,
including all liability and expense for any restoration, clean-up, disposal, or
removal that may be incurred as a result of the existence or discovery of
Hazardous Substances or other deleterious substances in, on, or under the
Properties, regardless of when the events occurred that give rise to such
condition, and the assumptions and indemnifications by Buyer set forth in this
Section shall expressly cover and include such matters. Except as otherwise
provided in this Section, Seller agrees to indemnify Buyer against any and all
claims, actions, liabilities, damages, costs or expenses (including court costs
and attorneys' fees) of any kind or character arising out of or otherwise
relating to its ownership or operation of the Properties prior to the Effective
Date. Any waste, contaminants, substances, or materials that were present or
stored on the Properties prior to Closing and that were shipped, transferred,
removed, or disposed of off the Properties prior to Closing are the sole
responsibility of Seller, and Seller agrees to indemnify and hold Buyer harmless
from and against any and all claims, actions, liabilities, damages, costs, or
expenses (including court costs and attorneys' fees) relating to such waste,
contaminants, substances, or materials. THE ASSUMPTIONS AND INDEMNIFICATIONS SET
FORTH IN THIS SECTION SHALL APPLY WHETHER OR NOT SUCH DUTIES, OBLIGATIONS, OR
LIABILITIES, OR SUCH CLAIMS, ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES,
LOSSES, COSTS, OR EXPENSES 

                                      17
<PAGE>
 
ARISE OUT OF (I) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE,
CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF SELLER OR ANY OTHER INDEMNIFIED
PARTY, OR (II) STRICT LIABILITY.

     14.  Disclaimer of Warranties.  THE EXPRESS REPRESENTATIONS AND WARRANTIES

CLOSING SHALL BE DEEMED TO HAVE WAIVED) ITS RIGHT TO INSPECT, THE PROPERTIES FOR
ALL PURPOSES AND SATISFIED ITSELF AS TO THEIR PHYSICAL AND ENVIRONMENTAL
CONDITION, BOTH SURFACE AND SUBSURFACE, INCLUDING, BUT NOT LIMITED TO,
CONDITIONS SPECIFICALLY RELATED TO THE PRESENCE, RELEASE, OR DISPOSAL OF
HAZARDOUS SUBSTANCES, SOLID WASTES, ASBESTOS OR OTHER MANMADE FIBERS OR
NATURALLY OCCURRING RADIOACTIVE MATERIALS ("NORM") IN, ON, OR UNDER THE
PROPERTIES. BUYER IS RELYING SOLELY UPON ITS OWN INSPECTION OF THE PROPERTIES,
AND BUYER SHALL, EXCEPT AS PROVIDED OTHERWISE HEREIN, ACCEPT ALL OF THE SAME "AS
IS, WHERE IS." WITHOUT LIMITATION OF THE FOREGOING, SELLER MAKES NO WARRANTY OR
REPRESENTATION, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, AS TO THE ACCURACY OR
COMPLETENESS OF ANY DATA, REPORTS, RECORDS, PROJECTIONS, INFORMATION, OR
MATERIALS NOW, HERETOFORE, OR HEREAFTER FURNISHED OR MADE AVAILABLE TO BUYER IN

          -----------                                                          
parent and subsidiary companies and other affiliates, and their directors,
officers, employees, and agents from and against any and all claims,
obligations, actions, liabilities, losses, damages, costs, or expenses
(including court costs and attorneys' fees) of any kind or character arising out
of or resulting from any agreement, arrangement, or understanding by, or on
behalf of, Seller with any broker or finder in connection with this Agreement or
the transaction contemplated hereby.  Buyer agrees to indemnify and hold
harmless Seller Group from and against any and all claims, obligations, actions,
liabilities, losses, damages, costs, or expenses (including court costs and
attorneys' fees) of any kind or character arising out of or resulting from any
agreement, arrangement, or understanding by, or on behalf of, Buyer with any
broker or finder in connection with this Agreement or the transaction

     16.  Casualty Loss.  If the Properties are damaged by fire or other
          -------------                                                 
casualty prior to Closing, this Agreement shall remain in full force and effect.
Seller shall have no obligation to repair any portion of the Properties so
damaged.  If Seller elects not to repair such a damaged portion of the
Properties, Buyer either may treat such portion of the Properties as if it had
an Asserted Defect or may elect not to adjust the Purchase Price therefor. If
Buyer elects hereunder to treat the damaged portion of the Properties as if it
had an Asserted Defect, the procedure provided for in Section 8. shall apply to
such portion of the Properties, and all rights to insurance proceeds and claims
against third parties related thereto shall belong to Seller. If Buyer elects
hereunder not to adjust the Purchase Price for such damaged portion of the
Properties, and if Seller is entitled to any claims under an insurance policy
with respect to such damage, Seller either shall collect and pay over, or
assign, such insurance claims to Buyer. In addition, if Buyer elects hereunder
not to adjust the Purchase Price for such damaged portion of the Properties,
Seller shall assign unto Buyer all claims against third parties with respect to
such damage. Buyer shall then take title to such portion of the Properties
without reduction of the Purchase Price. If Seller elects to repair a damaged
portion of the Properties, all rights to insurance proceeds and claims against
third parties related thereto shall belong to Seller.

          ----------------------                                             
Seller in Section 4. and by Buyer in Section 5. shall be continuing and shall be
true and correct on the Closing Date with the same force and effect as if made
at that time (and shall inure to the benefit of the respective successors and
assigns of Buyer and Seller).  All such representations and warranties shall
survive the Closing and the delivery of the Assignment and Bill of Sale.  The
obligations of the parties under Section 11. (to the extent the same are, by
agreement, not performed at Closing), and Sections 12., 13., 14., 15., 17., 18.,
and 19. also shall survive the Closing (subject to any limitations set forth in
such Sections) and the delivery of the Assignment and Bill of Sale.

     19.  Miscellaneous Matters.
          --------------------- 

          (a) After the Closing, Seller and Buyer shall execute and deliver, and
     shall otherwise cause to be executed and delivered, from time to time, such
     further instruments, notices, division orders, transfer orders, and other
     documents, and do such other and 

                                      20
<PAGE>
 
     further acts as reasonably may be necessary more fully and effectively to
     grant, convey, and assign the Properties to Buyer.

          (b) Except as provided in the following sentence, neither party shall
     have the right to assign its rights under this Agreement without the prior
     written consent of the other party, and any such assignment in violation of
     this provision shall be void.  Without Buyer's consent, Seller may assign
     its rights under this Agreement to a direct or indirect parent of Seller,
     to a direct or indirect subsidiary of Seller, or to an entity that is a
     direct or indirect subsidiary of a direct or indirect parent of Seller.

          (c) On the Closing Date (and upon the delivery to Buyer of the
     Assignment and Bill of Sale), Buyer shall succeed to the position of Seller
     with respect to all gas imbalances (whether wellhead imbalances or pipeline
     or gathering imbalances) and to the position of Seller with respect to all
     make-up obligations.  As a result of such succession, Buyer (i) shall be
     entitled to receive any and all benefits, including payments of proceeds of
     production in excess of amounts that it would otherwise be entitled to
     produce and receive by virtue of ownership of the Properties, that Seller
     would have been entitled to receive by virtue of such position and (ii)
     shall be obligated to suffer any detriments (whether the same are in the
     form of obligations to deliver production that would have otherwise been
     attributable to its ownership of the Properties without receiving full
     payment therefor, or are in the form of the obligation to make payment in
     cash) that Seller would have been obligated to suffer by virtue of such
     positions.

          (d) To the extent applicable to the transaction contemplated hereby,
     or any portion thereof, Buyer waives the provisions of the Texas Deceptive
     Trade Practices Act, Chapter 17, Subchapter E, Sections 17.41 through
     17.63, inclusive (other than Section 17.555 which is not waived), Texas
     Business and Commerce Code.  In connection with such waiver, Buyer hereby
     represents and warrants to Seller that Buyer (a) is in the business of
     seeking or acquiring, by purchase or lease, goods or services for
     commercial or business use, (b) has assets of Five Million and No/100
     Dollars ($5,000,000.00) or more according to its most recent financial
     statement, (c) has knowledge and experience in financial and business
     matters that enable it to evaluate the merits and risks of the transaction
     contemplated hereby, and (d) is not in a significantly disparate bargaining
     position.

          (e) Any confidentiality agreement executed by Buyer and Seller in
     connection with the transaction contemplated hereby remains in full force
     and effect and is not superseded or modified by this Agreement.

          (f) This Agreement contains the entire understanding of the parties
     hereto with respect to the subject matter hereof and supersedes all prior
     agreements, understandings, negotiations, and discussions among the parties
     with respect to such subject matter, except as provided in Sections
     6.(a)(i) and 19.(e) with respect to any confidentiality agreement.

     The headings contained in this Agreement are for convenience only and shall
     not control or affect the meaning or construction of any provision of this
     Agreement. Within this Agreement, words of any gender shall be held and
     construed to cover any other gender, and words in the singular shall be
     held and construed to cover the plural, unless the context otherwise
     requires. Time is of the essence in this Agreement.

          (g) This Agreement may be amended, modified, supplemented, restated,
     or discharged (and provisions hereof may be waived) only by an instrument
     in writing signed by the party against whom enforcement of the amendment,
     modification, supplement, restatement, or discharge (or waiver) is sought.

          (h) Each party shall bear and pay all expenses it incurred in
     connection with the transaction contemplated by this Agreement.

          (i) This Agreement shall be binding on the parties hereto and their
     respective successors and assigns.

          (j) This Agreement may be executed in two or more counterparts, each
     of which shall be deemed an original, but all of which shall constitute one
     and the same instrument.  It shall not be necessary for both parties to
     sign the same counterpart.

          (k) WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW, THIS AGREEMENT
     SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS
     OF THE STATE OF TEXAS APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED
     ENTIRELY WITHIN SUCH STATE AND BY THE LAWS OF THE UNITED STATES OF AMERICA,
     EXCEPT THAT, TO THE EXTENT THE LAW OF A STATE IN WHICH THE PROPERTIES ARE
     LOCATED NECESSARILY GOVERNS, THE LAW OF SUCH STATE SHALL, TO SUCH EXTENT,
     APPLY TO THE PROPERTIES.

          (l) Prior to Closing, Buyer shall not issue any publicity or press
     release concerning this Agreement or the transaction contemplated hereby
     without the prior written consent of Seller, unless, in the written opinion
     of legal counsel acceptable to Seller, such disclosure is required by
     applicable law or other applicable rules or regulations of any governmental
     authority or stock exchange and such publicity or press release contains no
     more than the minimum information necessary to comply therewith.  This
     provision shall not replace or restrict any provision in any prior
     agreement between the parties affecting confidentiality or the disclosure
     of information about the Properties.


     IN WITNESS WHEREOF, this Agreement is executed by the parties hereto on the
date set forth above.
