Item 2. Acquisition of Assets

     On March  31,  1998,  The  Home-Stake  Oil & Gas  Company  (the  "Company")
consummated   the  purchase  of  certain   natural  gas  properties  (the  "Bass
Properties")  from Sid R. Bass, Inc. et al for a purchase price of approximately
$6.6  million,  subject to certain  adjustments  for  operations  subsequent  to
January 1, 1998.  The purchase  price for such  properties  was determined in an
open sale in which competitive bids were submitted.  The Bass Properties contain
estimated  proved reserves of  approximately  6.4 Bcf of natural gas at December
31, 1997. In addition, management of the Company believes the properties contain
other  future  development  opportunities.  This  purchase  was  effective as of
January 1, 1998.

     The Bass  Properties  consist of 18  non-operated  producing gas properties
located  in three  producing  fields in  Oklahoma.  The  largest of these is the
Wilburton  Field located in Latimer County.  This interest  includes 9 producing
wells comprising 99.6% of the total value of the Bass Properties.  The remaining
9 properties are located in Beckham, Garvin, Lincoln and Washita Counties.

     On March 31, 1998,  the Company  entered into a new  financing  arrangement
with  NationsBank,  N.A. to finance the acquisition of the Bass Properties.  The
new  bank  note is due May 1,  2000  and  provides  for  monthly  maturities  of
$110,000, plus interest. Interest will be at bank prime less 1/2% and certain of
the Company's  producing  properties were pledged to collateralize  the loan. In
addition,  the Company has a new revolving  bank line of credit in the amount of
$5,000,000  available  until May 1, 1999 which provides for monthly  payments of
interest on the outstanding borrowings at bank prime less 1%. In connection with
this line of credit,  the Company will pay a  commitment  fee of one-half of one
percent (1/2%) per annum on the unused portion of the line.

     In connection with the Company's bank loans and credit facility,  there are
certain covenants which require,  among other things,  that the Company maintain
(i) a ratio of cash flow  (defined  in the loan  agreement  to be income  before
income taxes plus depreciation,  depletion and amortization  expense) to current
maturities  of  long-term  debt of more than 1.75 to 1.0,  (ii) a ratio of total
liabilities  to  stockholders'  equity of not more than 1.0 to 1.0,  and (iii) a
minimum  net worth of not less than  $20,000,000.  In  addition,  the  Company's
annual cash dividends are limited to the lesser of $550,000 or net income.

Item 7.    Financial Statements and Exhibits

     (a)   Financial statements of businesses acquired.

           It is  impractical to provide any of the financial  information  with

                           PURCHASE AND SALE AGREEMENT

     This  Agreement,  dated March 5, 1998 is made by and between the  signatory

                              W I T N E S S E T H:

terms and conditions of this Agreement.

     NOW, THEREFORE, In consideration of the mutual promises made herein and the
benefits to be derived hereunder, and other good and valuable consideration, the
sufficiency of which is hereby acknowledged, Seller and Buyer agree as follows:

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

     (a) All rights, titles, and interests of Seller in and to: 1) the oil, gas,
     and mineral  leases and  mineral  interests  described  in Exhibit A hereto
     (including landowner's royalty and any ratifications and amendments to such
     leases,  whether or not such  ratifications and amendments are described in
     Exhibit A); and 2) the wells described in Exhibit B hereto;

     (b) All rights,  titles,  and  interests  of Seller in and to, or otherwise

     rules, regulations,  or other official acts of any federal, state, or other
     authority  having  jurisdiction,   and  voluntary  unitization  agreements,
     designations,  and  declarations)  relating to the properties  described in
     subsection  1.(a) to the extent such  rights,  titles,  and  interests  are
     attributable to the properties described in subsection 1.(a);

     (c) All rights,  titles,  and  interests of Seller in and to all  presently
     existing  and  valid  production  sales  contracts,  operating  agreements,
     farmout agreements,  farmin agreements,  and other agreements and contracts
     that relate to any of the  properties  described  in  subsections  l.a. and
     l.b., to the extent such rights,  titles,  and interests are assignable and
     attributable to the properties described in subsections 1.(a) and 1.(b);

     (d)  All  rights,   titles,   and   interests  of  Seller  in  and  to  all
     rights-of-way, easements, surface leases, permits, and licenses appurtenant

     operation, or maintenance thereof.

Seller has in its files, excluding any data which Seller cannot provide to Buyer
without  breaching,  or risking a breach of, a confidentiality  agreement with a
third party; provided,  however, Seller agrees to use its best efforts to obtain
the consent of any such third party to the furnishing of such data to Buyer.

     2. Purchase Price.  The unadjusted  purchase price for the Properties shall
be Six Million Six Hundred Eighty Five Thousand dollars  ($6,685,000.00) payable
in United States dollars  (herein called the "Base  Purchase  Price").  The Base
Purchase  Price may be adjusted,  as provided in Sections  7.(c) and 11. hereof.
The Base  Purchase  Price,  as so adjusted and as  otherwise  adjusted by mutual
agreement of the parties herein, shall be called the "Purchase Price."

     3. Deposit.  Upon entering into this Agreement,  as evidence of good faith,
Buyer shall pay to Seller Six Hundred Sixty Eight Thousand Five Hundred  dollars
($668,500.00)  hereinafter called the "Deposit".  If Buyer and Seller consummate
the transaction  contemplated  hereby in accordance  with the terms hereof,  the
Deposit  shall be  applied  to the  Purchase  Price.  If Buyer and Seller do not
consummate the transaction  contemplated hereby because of a material default by
Seller, Seller shall return the Deposit to Buyer. Except as provided in Sections
12.  and  13.,  if  Buyer  fails  or  refuses  to  consummate  the   transaction
contemplated  hereby,  in violation of the provisions of this Agreement,  Seller
may retain the Deposit.  The Deposit is neither an earnest  money deposit nor an
amount  pre-determined  for purposes of  liquidated  damages.  Forfeiture of the
Deposit as  provided  herein  shall be in  addition  to, and not in lieu of, the
rights and remedies  Seller may have at law or in equity for Buyer's  failure to
perform as provided  in this  Agreement.  In no event  shall the Deposit  accrue
interest.

     4. Allocation of Base Purchase Price. Buyer has allocated the Base Purchase
Price  to the  Properties  including  equipment  and  personal  property.  These

          THAT MAY BE PROVIDED BY OTHERS.

          (ii) Seller shall make a good faith  effort to give Buyer,  or Buyer's
          authorized  representatives,  who have a legitimate  need to know,  at
          reasonable  times and upon adequate notice to Seller,  physical access
          to the Properties for the purpose of inspecting same. Buyer recognizes
          that some of the  Properties  are  operated by third  parties and that
          Seller's ability to obtain access to such  properties,  and the manner
          and extent of such  access,  is  subject to the  consent of such third
          parties. Buyer agrees to comply fully with the rules, regulations, and
          any instructions  issued by Seller or third party (where a Property is
          operated  by such third  party)  regarding  the actions of Buyer while
          upon, entering, or leaving the Properties.

          (iii) If Buyer  exercises  rights  of access  under  this  Section  or
          otherwise,  or conducts examinations or inspections under this Section
          or  otherwise,   then  (a)  Buyer  will  be  accompanied  by  Seller's
          representative  at  all  times;  (b)  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

                                        4

<PAGE>



          directors, officers, employees, attorneys,  contractors, and agents in
          connection therewith; and (c) BUYER SHALL RELEASE, INDEMNIFY,  DEFEND,
          AND HOLD HARMLESS SELLER (AND ITS PARENT,  SUBSIDIARY  COMPANIES,  AND
          OTHER AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS,  EMPLOYEES,
          ATTORNEYS, CONTRACTORS, AND AGENTS) (HEREINAFTER COLLECTIVELY REFERRED
          TO AS "SELLER  GROUP")  FROM ANY AND ALL  CLAIMS,  ACTIONS,  CAUSES OF
          ACTION,  LIABILITIES,  DAMAGES, LOSSES, COSTS, OR EXPENSES (INCLUDING,
          WITHOUT  LIMITATION,  COURT  COSTS AND  ATTORNEYS'  FEES),OR  LIENS OR
          ENCUMBRANCES  FOR  LABOR OR  MATERIALS,  ARISING  OUT OF OR IN ANY WAY
          CONNECTED WITH SUCH ACCESS, EXAMINATION, AND INSPECTION. 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,
          SIMPLE   NEGLIGENCE,   CONCURRENT   NEGLIGENCE,   ACTIVE  OR   PASSIVE
          NEGLIGENCE, OR OTHERWISE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE
          OR WILLFUL  MISCONDUCT) OF SELLER OR ANY OTHER  INDEMNIFIED  PARTY, OR
          (ii) STRICT LIABILITY.

     (b) Seller shall  continue to conduct its business in its ordinary  course,
     and in accordance  with all applicable  ordinances,  statutes,  rules,  and
     regulations of all local, state, and federal governments.  Seller shall not
     enter  into or  assume  any  contract  or  commitment  which  is not in the
     ordinary course of business as heretofore conducted in association with the
     Properties  and shall carry on its business and operate the Properties as a
     reasonably prudent operator.  Subject to existing contractual  obligations,
     Seller shall not conduct,  or commit to participate in, on behalf of Buyer,
     any  operation  affecting  the  Properties  in which  Seller's net share of
     expense is greater than $50,000.00 for such operation without Buyer's prior
     written  consent.  However,  Seller  may take such  steps  and  incur  such
     expenses  as it  deems  necessary  in its  sole  opinion  to  deal  with an
     emergency to safeguard any part of the Property  without  first  consulting
     with Buyer.  As soon as possible after the  emergency,  Seller shall advise
     Buyer of such  emergency  action.  Except as set  forth in this  Agreement,
     Seller shall not sell, assign,  transfer,  mortgage,  farmout, or otherwise
     dispose of, abandon, or encumber any material portion of the Properties.

     (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,  (i) all  preferential  rights to purchase that
     would  apply to the  transaction  contemplated  hereby and (ii) 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.  Seller shall have
     no obligation hereunder other than to attempt to identify such preferential
     rights and to request such waivers. Seller shall not be obligated to assure
     that such waivers 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 value allocated to such interest according to Exhibit E.
     To the extent that such an interest is actually sold to a party  exercising
     such a  preferential  right,  it shall  be  excluded  from the  transaction
     contemplated  hereby,  and the Base Purchase  Price shall be 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  necessary  filings in  connection  with the
     transaction  contemplated  by this Agreement under the HSR Act. 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


                                        5

<PAGE>



     promptly  make any  appropriate  or necessary  subsequent  or  supplemental
     filings,  and shall  furnish to Seller copies of all filings made under the
     HSR Act at the  same  time  they are  filed  with  the  FTC.  Seller  shall
     cooperate with Buyer as to all filings required by the HSR Act.

     (e) After both parties have executed this  Agreement,  Seller shall deliver
     to Buyer a copy of its "pay list" for each well  listed on Exhibit B (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  property);  and, a
     list of all  parties  for  whom  it is  holding  in  suspense  proceeds  of
     production.  Seller does not  represent or warrant to Buyer the accuracy of
     the "pay lists" so delivered.

     8. Due Diligence Reviews.

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

          (i) As of the Effective Date,  Seller's  ownership of a well listed on
          Exhibit B hereto either, (A) entitles Seller to receive a share of the
          oil, gas, and other hydrocarbons  produced from, or allocated to, such
          well that is less than the share set forth on  Exhibit B for such well
          in the columns  headed "Net Revenue  Interest  (NRI)" and  "Overriding
          Royalty Interest (ORI)", excepting any decreases caused by an increase
          in  the   landowner's   royalty  payable  to  the  Federal  and  State
          Governments or pursuant to contractual obligations, including, without
          limitation,  sliding  scale  overriding  royalties,  which are tied to
          amount of production,  or as mandated by Federal and State statutes as
          promulgated in the respective Federal and State Rules and Regulations;
          or, (B) causes  Seller to bear a share of the cost of  operating  such
          well  greater  than the share set forth on  Exhibit B for such well in
          the column headed  "Working  Interest (WI)"  (without a  proportionate
          increase in the share of  production  to which Seller is entitled from
          such well);

          (ii) Seller's  ownership of a Property 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,  or (C) a lien under an operating  agreement
          or  similar  agreement,  to the extent  the same  relates to  expenses
          incurred that are not yet due;

          (iii)Seller's  ownership  of a Property  is subject to a  preferential
          right to  purchase,  unless a waiver of such  right has been  obtained
          with respect to the transaction  contemplated hereby or an appropriate
          tender of the  applicable  interest has been made to the party holding
          such right and the period of time  required for such party to exercise
          such right has expired without such party exercising such right;

          (iv) Seller's ownership of a Property is subject to an imperfection in
          title that,  if asserted,  would cause a Defect,  as defined in clause
          (i) above, to exist, and such imperfection in title normally would not
          be waived by reasonable and prudent persons engaged in the oil and gas
          business with knowledge of all the facts and their legal  implications
          and would  materially  impair or prevent Buyer from receiving  payment
          from the  purchasers  of  production,  and would  prevent the economic
          benefit Buyer could reasonably expect by acquiring the Properties;

                                        6

<PAGE>



          (v) Seller's  ownership of a  non-producing  Property is subject to an
          imperfection  in  title  that,  if  asserted,   would  cause  Seller's
          ownership as shown on Exhibit A to be less; and such  imperfection  in
          title normally  would not be waived by reasonable and prudent  persons
          engaged in the oil and gas  business  with  knowledge of all the facts
          and their legal implications and would materially prevent the economic
          benefit Buyer could reasonably expect by acquiring such Property.

     (b) Buyer may conduct,  to the extent it deems  appropriate and at its sole
     risk and cost, such  examinations and  investigations as it may choose with
     respect to the Properties in order to determine  whether  "Defects"  exist.
     Unless waived, Buyer shall notify Seller in writing of such Defects as soon
     as they are identified,  but no later than March 27, 1998, [unless extended
     pursuant to 14.(i) or 14.(ii)]  (hereinafter  "Defect Notice Date").  Those
     Defects  identified  in such notice to Seller are herein  called  "Asserted
     Defects".  Such  notification  shall include a description  of the Asserted
     Defect,  the  lease(s)  described  on Exhibit A affected  by such  Asserted
     Defect,  the  well(s)  listed on  Exhibit B to which  the  Asserted  Defect
     relates,  and all supporting  documentation  reasonably  necessary fully to
     describe  in detail  the  basis  for the  Asserted  Defect;  and,  for each
     property,  lease and  applicable  well,  the size of any variance from "Net
     Revenue Interest (NRI)",  "Overriding  Royalty Interest (ORI)", or "Working
     Interest  (WI)" set forth in Exhibit B that does or could  result from 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
     timely 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 also 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,  if Seller desires  additional time to attempt to cure (including
     determining  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  with  respect to any  Asserted  Defect,  to
     indemnify  and hold Buyer  harmless  from and  against  any damages or loss
     (including  consequential  damages,  special  damages,  or similar damages)
     Buyer may suffer as a result of a third party claim based on such  Asserted
     Defect. If Seller elects to indemnify Buyer as to an Asserted Defect,  such
     Asserted Defect will be treated under this Agreement as cured.

     (c) Buyer shall have the right to make an  environmental  assessment of the
     Properties  during the period  beginning  on the date of  execution of this
     Agreement and ending on the Defect Notice Date.  Subject to Buyer's  rights
     to access  under  Section 7.  hereof,  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
     Buyer may deem necessary or appropriate  for the preparation of appropriate
     engineering  and other  reports in  relation  to the  Properties  and their
     physical and  environmental  condition.  If Buyer  proposes to undertake an
     environmental  assessment,  Buyer's  proposed plan,  the  consultants to be
     used,  and testing  protocol must be approved by Seller before the work may
     begin,  which  approval  will not be  unreasonably  withheld.  Buyer agrees
     promptly  to  provide  to  Seller a copy of the  environmental  assessment,
     including any reports, data, and conclusions. Buyer shall keep all data and
     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.


                                        7

     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 THE MAKING OF THE
     ENVIRONMENTAL  ASSESSMENT INCLUDING, BUT NOT LIMITED TO, INJURY TO OR DEATH
     OF PERSONS OR DAMAGE TO PROPERTY  OCCURRING IN, ON, OR ABOUT THE PROPERTIES
     AS A RESULT OF SUCH ACTIVITIES  (EXCEPT ANY SUCH INJURIES OR DAMAGES CAUSED
     SOLELY BY THE GROSS  NEGLIGENCE OR WILLFUL  MISCONDUCT OF ANY MEMBER OF THE
     SELLER GROUP).

     (d) 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.

     9. Adverse Environmental Conditions.

     (a) Buyer shall have until the Defect  Notice Date to notify  Seller of any
     material  adverse  environmental  condition of the  Properties  which Buyer
     deems  unacceptable  and provide  evidence of the  condition to Seller.  An
     environmental  condition  is a  material  adverse  environmental  condition
     ("Condition") only if the following criteria are met:

          (i)  The  environmental  condition  would  have  been  required  to be
          remediated on the Effective Date under the Environmental Laws; and,

          (ii)  The  total  cost  to  remediate  all  environmental   conditions
          identified by Buyer  affecting the Properties to the state required by
          the  Environmental  Laws  is  reasonably  estimated  to  be  at  least
          $100,000.00.

     (b) "Environmental Law" shall mean any federal,  state, or local law, rule,
     regulation,  order, or ordinance in effect as of the Effective Date of this
     Agreement  pertaining to protecting  the public  health,  welfare,  and the
     environment.

     (c) At Closing,  Seller may elect any of the following provided a Condition
     exists:

          (i) Decrease the Base Purchase Price by a mutually  acceptable  amount
          reflecting  Seller's   proportionate   share,  based  on  its  working
          interest,  of the cost  reasonably  estimated to remediate a Condition
          affecting  the   Properties  to  such  a  state  as  required  by  the
          Environmental Laws;

          (ii) Remove the affected Properties from this Agreement and adjust the
          Base Purchase Price by the amount allocated to the affected Properties
          according to Exhibit E.

          (iii) Remedy,  or agree to remedy,  the Condition,  as provided below;
          or,

          (iv) Terminate this Agreement.

     (d) If option (c)i.  above is chosen,  Buyer shall be  responsible  for any
     remediation. If the actual cost to remediate a Condition exceeds the amount
     of the  estimate,  Buyer shall pay the  additional  costs to remediate  the
     Condition as required by applicable  law. If the actual cost to remediate a
     Condition is less than the amount of the estimate,  Buyer shall be entitled
     to retain the amount by which the estimate exceeds the actual cost.

     (e) If option  (c)iii.  above is chosen,  the  following  shall  govern the
     remediation:


                                        8

<PAGE>



          (i) Seller shall be responsible for all negotiations and contacts with
          federal,  state, and local agencies and authorities with regard to the
          Condition or remediation.  Buyer may not make any independent contacts
          with any agency,  authority,  or other third party with respect to the
          Condition or remediation and will keep all  information  regarding the
          Condition and remediation confidential, except in each instance to the
          extent required by applicable law.

          (ii) Seller shall  remediate the Condition to the state agreed upon by
          Seller and Buyer, but in no event will Seller be required to remediate
          the Condition beyond the state required by the Environmental Laws.

          (iii) Buyer will use its best efforts to obtain access to the affected
          Properties  after  Closing  to  Seller  and third  parties  conducting
          assessments or remediation,  to the extent and as long as necessary to
          conduct and complete the  assessment  or  remediation  work, to remove
          equipment  and  facilities,   and  to  perform  any  other  activities
          reasonably necessary in connection with assessment or remediation.

          (iv) Buyer will use its best  efforts not to interfere  with  Seller's
          ingress and egress or assessment  or  remediation  activities.  Seller
          shall make  reasonable  efforts to perform  the work so as to minimize
          disruption to Buyer's business activities and to the Properties.

          (v) Seller shall continue remediation of the Condition until the first
          of the following occurs:

               (1) The  appropriate  governmental  authorities  provide  written
               notice to  Seller or Buyer  that no  further  remediation  of the
               Condition is required; or

               (2) Seller and Buyer  jointly  agree that the  Condition has been
               remediated to the state required by the Environmental  Laws or as
               agreed by the parties.

               Upon the occurrence of (1) above,  Seller shall notify Buyer that
               remediation  of the  Condition  is complete and provide a copy of
               the  notification  described  in  (1)  above.  Upon  delivery  of
               Seller's notice,  Seller shall be released from all liability and
               have  no  further   obligations  under  any  provisions  of  this
               Agreement in connection with a Condition.

          (vi) Until Seller  completes  remediation  of a Condition,  Seller and
          Buyer will each notify the other of any pending or  threatened  claim,
          action,  or  proceeding by any authority or private party that relates
          to or would affect the Condition,  the assessment,  or the remediation
          of the affected Properties.

          (vii) If Seller will assess or remediate the affected Properties after
          Closing,   the  Assignment  and  Bill  of  Sale  or  other  recordable
          instrument will restate the rights and obligations of this section.

     10. Remedial  Action;  Compliance with Law. When any lease  terminates,  an
interest in which has been assigned under this  Agreement,  Buyer, to the extent
it  can do so as  non-operator  will  undertake  testing,  assessment,  closure,
reporting,  or remedial  action with respect to the  Properties  affected by the
termination as is necessary to satisfy all local, state, or federal requirements
in effect at that time and necessary to restore the Properties.  Buyer agrees to
release,  indemnify,  hold  harmless,  and  defend  Seller as to all  claims and


                                        9

<PAGE>



liabilities  arising  therefrom  to the same extent as described in Sections 17.
and 18.

     11. Certain Price Adjustments to the Base Purchase Price.

     (a) If Buyer  presents  Asserted  Defects  to  Seller  as a part of the due
     diligence reviews provided for in Section 8. above, and if Seller is unable
     or unwilling to cure such Asserted  Defects  prior to Closing,  or if Buyer
     has  elected to treat a Property  affected by a casualty  loss  pursuant to
     Section 22. as if it were a Property  affected by an Asserted Defect,  then
     an  appropriate  adjustment to the Base Purchase  Price to account for such
     Asserted Defects shall be made by using those values set forth in Exhibit E
     hereto and those  Properties,  or any part  thereof,  associated  with such
     Asserted  Defects  shall be deleted from this  Agreement  and any rights of
     Buyer thereto shall terminate.

     (b) If it is determined that Seller's  interest in a well listed on Exhibit
     B is  greater  or lesser  than the  interest  shown for such well under the
     columns  headed  "Net  Revenue  Interest  (NRI)"  and  "Overriding  Royalty
     Interest  (ORI)" on Exhibit B, then Seller or Buyer may propose an increase
     or decrease, as applicable,  in the Base Purchase Price, in which case such
     increase or decrease  shall be handled in the same manner as provided above
     with respect to adjustments for Asserted  Defects;  provided that the party
     making such  determination  shall notify the other party of such adjustment
     on or before the  Defect  Notice  Date.  Buyer  shall  have an  affirmative
     obligation to disclose to Seller  circumstances  discovered by Buyer in its
     due diligence  review that could result in an increase in the Base Purchase
     Price hereunder.

     (c)  Notwithstanding  the  adjustments  to be made pursuant to  subsections
     11.(a)and 11.(b) above, if such adjustments do not exceed  $100,000.00,  no
     such  adjustments  shall  be made  and none of the  Properties  that  would
     otherwise have been excluded  pursuant to subsection  11.(a) above shall be
     excluded.  If the adjustments to be made pursuant to subsections 11.(a) and
     11.(b)  above,  do exceed  $100,000.00,  the Base  Purchase  Price shall be
     adjusted by the amount of such adjustments.

     12. 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,
     except  as to  changes  specifically  contemplated  by  this  Agreement  or
     consented to by Buyer in writing.

     (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 in writing.

     (c) If applicable,  Buyer and Seller shall have received  approval from the
     FTC under the HSR Act of the transaction contemplated by this Agreement, or
     shall have received notification that the waiting period under such act has
     been terminated, or the waiting period under such act shall have expired.

     (d) The  Base  Purchase  Price  increase  or  decrease  resulting  from the
     adjustments to be made pursuant to  subsections  11.(a) and 11.(b) does not
     exceed Seven Hundred Fifty Thousand dollars ($750,000.00).

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

If any such condition precedent to the obligations of Buyer under this Agreement
is not met as of the Closing  Date,  this  Agreement  may be  terminated  at the
option of Buyer. If Buyer thus  terminates this Agreement,  the Deposit shall be
returned  to Buyer and the  parties  shall  have no further  obligations  to one
another  hereunder  (other  than  the  indemnifications  contained  in  Sections
7.(a)(iii),  8.(c),  and 21.  hereof,  which shall  survive  such  termination).
Notwithstanding  the  foregoing,  if a  condition  set forth  above,  other than
condition  12. (c) or 12.(d),  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  some,  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 process set forth
in Section 11. above.

     13. Conditions Precedent to Seller's Obligations. Seller's
obligations under this Agreement are subject to 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, 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 from the
     FTC under the HSR Act of the transaction contemplated by this Agreement, or
     shall have received notification that the waiting period under such act has
     been terminated, or the waiting period under such act shall have expired.

     (d) The Base Purchase Price reduction  resulting from the adjustments to be
     made  pursuant  to  subsections  11.(a)  and 11.(b)  does not exceed  Seven
     Hundred Fifty Thousand dollars $(750,000.00).

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

If any  such  condition  precedent  to the  obligations  of  Seller  under  this
Agreement is not met as of the Closing Date, this agreement may be terminated at
the option of Seller.  If Seller  terminates  this agreement  because of Buyer's
failure to fulfill condition 13.(a) or 13.(b), the Deposit shall not be returned
to Buyer.  If Seller  terminates  this Agreement  because of conditions  13.(c),
13.(d), or 13.(e),  the Deposit shall be returned to Buyer.  Thereafter,  Seller
and Buyer shall have no further obligations to one another hereunder (other than
the  indemnifications  contained in Section  7.(a)(iii),  8.(c), and 21. hereof,
which shall survive such termination).

     14. The  Closing.  If the  conditions  referred  to in Section  12. of this
Agreement (the "Conditions Precedent to Buyer's Obligations") and Section 13. of
this Agreement (the  "Conditions  Precedent to Sellers  Obligations")  have been
satisfied or waived,  the  consummation of the transaction  contemplated  hereby
("Closing") shall take place in the offices of Seller, at 201 Main Street,  Fort
Worth, Texas 76102, on March 31, 1998, at 1:00 p.m. Central Standard Time, or at


                                       11

<PAGE>



such other date and time (i) as the Buyer and Seller may agree or, (ii) to which
Seller may postpone the Closing  pursuant to Section 8.(b) hereof (such date and
time herein called the "Closing Date"). At the Closing:

     (a) Seller shall:

          (i) Execute,  acknowledge,  and deliver to Buyer a  conveyance  of the
          Properties containing a special warranty of title (the "Assignment and
          Bill of  Sale"),  in the  form  attached  hereto  as  Exhibit  C (with
          Exhibits  A and B attached  thereto),  effective  as of seven  o'clock
          a.m.,  (7:00 a.m.) Central  Standard Time on January 1, 1998,  (herein
          called the "Effective Date");

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

          (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);

          (v) Deliver to Buyer  certificates in form and substance  satisfactory
          to Buyer,  effective  as of the Closing  Date and executed by Seller's
          duly authorized  officer,  partner,  or owner, as appropriate,  to the
          effect that (1) Seller has all requisite  corporate,  partnership,  or
          other power and authority to sell the  Properties on the terms of this
          Agreement and to perform its other  obligations  under this  Agreement
          and has fulfilled all corporate,  partnership,  or other prerequisites
          to closing this  transaction,  and (2) each  individual  executing the
          closing documents has the authority to act on behalf of Seller.

          (vi) Deliver possession of the Properties to Buyer.

     (b) 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  payable in
          United States  dollars equal to the amount as set forth on the Closing
          Settlement Statement as provided for in Section 16.(c) below;

          (ii)  Deliver to  Seller,  except to the  extent  waived by  Seller's,
          certificates in form and substance  satisfactory to Seller,  effective
          as of the  Closing  Date  and  executed  by  Buyer's  duly  authorized
          officer,  partner,  or owner, as  appropriate,  to the effect that (1)
          Buyer has all  requisite  corporate,  partnership,  or other power and
          authority to purchase the  Properties  on the terms of this  Agreement
          and to perform  its other  obligations  under this  Agreement  and has
          fulfilled  all  corporate,  partnership,  or  other  prerequisites  to
          closing  this  transaction,  and (2)  each  individual  executing  the
          closing documents has the authority to act on behalf of Buyer.

                                       12

<PAGE>




          (iii)  Execute  such  forms and take such  other  steps as Seller  may
          reasonably   require  to  (A)  succeed  Seller  with  respect  to  the
          Properties  under the rules and regulations of applicable  authorities
          and (B) assume any and all  liabilities  of Seller with respect to the
          wells described on Exhibit B; and,

          (iv) Take possession of the Properties.

     15. After  Closing.  Within  thirty (30) days after  Closing,  Seller shall
deliver to Buyer all of Seller's files related to the Properties,  including but
not limited to 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.  In addition,  Seller shall
deliver to Buyer any seismic data,  geological and  geophysical  data, and other
similar data, and any  interpretations  thereof or other data or records related
thereto except as expressly  provided in Section 1. hereof.  Seller shall retain
such files,  or copies  thereof,  or such  information as it deems necessary for
preparing  a Final  Settlement  Statement  as  provided  in Section  16., or for
purposes of filing tax returns  covering the Properties.  Any files or materials
retained by Seller after Closing pursuant hereto, shall be sent to Buyer as soon
as reasonably  practicable  after final  payment is made in accordance  with the
Final Settlement  Statement.  Seller may, at its own expense, have access to and
make copies of all, or any part thereof, of the files and records provided Buyer
hereunder at reasonable times and upon reasonable notice during regular business
hours for as long as the Properties remain in effect.

As to those wells which  Seller is  disbursing  proceeds of  production,  Seller
shall continue to collect  proceeds of production as long as it remains operator
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 its successor as operator.


     16. Certain Accounting Adjustments to the Purchase Price.

     (a)  Appropriate  adjustments  to the Purchase  Price shall be made between
     Buyer and Seller to reflect the following:

          (i) All rights to proceeds,  receipts,  reimbursements,  credits,  and
          income   attributable  to  the  Properties  and  accruing  before  the
          Effective Time, as defined below, shall be the property of Seller. All
          proceeds,  receipts,  credits, income, and charges attributable to the
          Properties  acquired by Buyer  hereunder and accruing on and after the
          Effective  Time  shall be the  property  of  Buyer.  As to  Properties
          operated by Seller and  purchased by Buyer  hereunder  and  concerning
          accounts  held  in  suspense,  Seller  will  pay in full  the  royalty
          accounts that were  suspended  because the amount due is less than the
          statutory  or  contractual  minimum  for  payment.  As  to  all  other
          suspended accounts,  if any, Seller shall transfer to its successor as
          operator all monies held in a suspended  account  which were  received
          for  production  produced  from or allocated to the  Properties on and
          after the  Effective  Time.  As to proceeds  received  for  production
          produced from or allocated to the Properties before the Effective Time
          and held in a  suspensed  account,  Seller may  either:  1) Retain the
          suspended  amounts  after  Closing  and,  upon proof  satisfactory  to
          Seller,  release the money to the proper  party;  or, 2) Transfer  the
          suspended  amounts to Buyer for future  disbursement.  Once  suspended
          amounts have been transferred to Buyer for future disbursement,  Buyer
          agrees to be responsible  for  disbursing the suspended  monies to the
          proper parties and shall release, indemnify, defend, and hold harmless


                                       13

<PAGE>



          the Seller Group from any and all claims,  actions,  causes of action,
          liabilities,  damages, losses, costs, or expenses (including,  without
          limitation, court costs and attorneys' fees), arising out of or in any
          way  connected  with making such  disbursements,  or failure to make a
          disbursement.

          (ii)  Seller  shall be  responsible  for and pay (A) all  charges  and
          invoices for costs and expenses (including,  without limitation, lease
          maintenance  payments,   drilling  and  operating  expenses,   capital
          expenditures, and overhead charges) accruing before the Effective Time
          and   attributable  to  the  Properties  and  (B)  necessary   royalty
          disbursements  of  proceeds  realized  from  the  sale  of  production
          produced  from and  allocated to the  Properties  before the Effective
          Time.  Buyer shall be  responsible  for payment of (C) all charges and
          invoices for costs and expenses (including,  without limitation, lease
          maintenance  payments,   drilling  and  operating  expenses,   capital
          expenditures, and operator overhead charges) accruing on and after the
          Effective Time and attributable to the Properties  acquired  hereunder
          and (D) necessary royalty  disbursements of proceeds realized from the
          sale of  production  produced  from and  allocated  to the  Properties
          acquired  hereunder on and after the Effective Time. All payments made
          by Seller  for items  under (C) above for which  Buyer is  responsible
          shall be reimbursed  by Buyer.  Seller shall  reimburse  Buyer for all
          monies  received by Seller from  non-operators  as payment of Seller's
          invoices for the  operations  of the wells  described on Exhibit B for
          periods on and after the Effective Time.

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

          (i) Seller has caused  such oil  storage  facilities  which  store oil
          produced from the  Properties to be gauged or strapped as of 7:00 a.m.
          Central Standard Time on the Effective Date,  hereinafter  referred to
          as the Effective Time. Seller also has caused the gas production meter
          charts  (or if such do not  exist,  the  sales  meter  charts)  or gas
          production  statements on the pipelines  transporting  gas  production
          from the  Properties to be read as of the Effective  Time. The results
          of such gauging,  strapping, or chart reading are conclusive and shall
          be made available to Buyer. The production in such storage  facilities
          or through such meters on the gas pipelines as of the  Effective  Time
          shall be owned by Seller; and,  thereafter,  production placed in such
          storage  facilities and gas production  passing  through the aforesaid
          meters on the  pipelines  shall be owned by Buyer,  insofar  as to the
          interests subject hereto as of Closing.

          (ii) All ad valorem,  production  and similar taxes  applicable to the
          Properties  shall  be  prorated  between  Seller  and  Buyer as of the
          Effective  Date.  Therefore,  all ad valorem,  production  and similar
          taxes for 1997 and prior years levied against the Properties  shall be
          borne and paid by Seller; and, all ad valorem,  production and similar
          taxes for 1998 and thereafter  levied against the Properties  shall be
          borne and paid by Buyer, irrespective if the amount levied is based on
          the previous year's production or any other basis.

          (iii) Each party shall be responsible for its own income taxes.

     (c) With respect to matters that can be  determined  as of Closing,  Seller
     shall prepare, in accordance with the provisions of this Agreement and with
     generally  accepted  accounting  principles,   a  statement  (the  "Closing
     Settlement  Statement")  setting forth each adjustment to the Base Purchase
     Price and to the Purchase Price to the best of Seller's knowledge,  whether

                                       14

<PAGE>



     upward or downward, as may be required in accordance herewith. Seller shall
     submit to Buyer the  Closing  Settlement  Statement  no later than five (5)
     days prior to the Closing  Date and shall  afford  Buyer access to Seller's
     records pertaining to the computation of the Closing Settlement  Statement.
     Prior to the  Closing,  Buyer and Seller  will  agree upon the  adjustments
     stated  therein  to be made to the  Purchase  Price,  or will  specify  the
     adjustments  to which  there  are  differences  and the  adjustments  to be
     omitted  therefrom.  Only the agreed upon  adjustments  shall be taken into
     account in computing the  adjustments  to be made to the Purchase  Price at
     Closing. Final adjustments to the Purchase Price to be made hereunder shall
     be made within one hundred-twenty (120) days after the Closing Date for all
     matters  other  than  Asserted  Defects  according  to (c)  hereinbelow  as
     follows:

     (d) As soon as  practicable  after the Closing,  and in no event later than
     sixty (60) days following the Closing Date,  Seller shall deliver to Buyer,
     in  accordance  with the  provisions of this  Agreement and with  generally
     accepted accounting principles,  a statement ("Final Settlement Statement")
     setting forth each adjustment under this Agreement which was not determined
     as of the Closing. Within sixty (60) days after Buyer's receiving the Final
     Settlement  Statement,  the Parties  shall agree upon the  adjustments  and
     payments  stated in such Final  Settlement  Statement,  and the net of such
     adjustments and payments shall be paid in cash to the appropriate  Party by
     the other Party  within five (5) days  following  agreement as to the Final
     Settlement Statement.

     17.  Assumption and  Indemnification.  SUBJECT TO THE PROVISIONS OF SECTION
20. BELOW,  UPON DELIVERY TO AND  ACCEPTANCE BY BUYER OF THE ASSIGNMENT AND BILL

indemnifications  made herein, shall survive the Closing and the delivery of the

extent the Parties intend for such  obligations  to be satisfied  after Closing.
Buyer shall have until the Defect  Notice Date in which to satisfy  itself as to
the quantity and quality of Seller's title to the Properties.

     26. Miscellaneous Matters.

     (a) Further Assurances.  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 further acts and things
     as may be reasonably necessary more fully and effectively to grant, convey,
     and assign the  Property to Buyer and to  effectuate  the  purposes of this
     agreement.

     (b) Assignability.  Except as provided below,  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.

     (c) Gas  Balances.  On the Closing  Date (and upon the delivery to Buyer of
     the Assignment and Bill of Sale), Buyer shall assume the position of Seller
     with  respect  to all gas  imbalances  affecting  the  Properties  acquired
     (whether  wellhead  imbalances or pipeline or gathering  imbalances) and to
     the position of Seller with respect to all make-up  obligations  unless the
     applicable  gas  balancing  agreement  requires a cash  settlement  when an
     interest is assigned,  in which event,  Seller  reserves the gas  imbalance

                                                             18

<PAGE>



     account  and  the  right  to the  cash  settlement.  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 be 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  be in  the  form  of  the
     obligation  to make payment in cash) that Seller would have been  obligated
     to suffer by virtue of such position.

     (d) Confidentiality  Agreement.  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.

     (e) Prior Entire Understanding/Headings/Gender. 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   above   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.

     (f)  Amendments.  This  Agreement may be amended,  modified,  supplemented,
     restated,  or discharged (and  provisions  hereof may be waived) only by an
     instrument executed by both parties.

     (g)  Associated  Expenses.  Each party  shall bear and pay all  expenses it
     incurred and that are associated with the transaction  contemplated by this
     Agreement.  Payment of  recording  fees,  filing  fees,  and any other fees
     imposed  on the  Properties  on and after  the  Effective  Date,  excluding
     Seller's income taxes, shall be paid by Buyer. Seller shall remit on behalf
     of Buyer all city,  county and state sales taxes due on the  equipment  and
     personal property  included in the Properties.  Buyer will reimburse Seller
     at the Closing for all such sales taxes paid on behalf of Buyer.

     (h) Successors and Assigns.  This Agreement shall be binding on the parties
     hereto  and  their  respective  heirs,  successors,   representatives,  and
     assigns.

     (i)  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
     counterparts,  each of which shall be deemed an original,  but all of which
     shall constitute one (1) and the same instrument. It shall not be necessary
     for both parties to sign the same counterpart.

     (j) Enforceability.  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 OKLAHOMA.

     (k)  Publicity.  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


                                       19

<PAGE>



     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.

     (l) Use of Seller's Name.  Buyer agrees that, as soon as practicable  after
     the  Closing,  it shall  remove or cause to be removed  the names and signs
     used by  Seller,  and all  variations  and  derivatives  thereof  and logos
     relating  thereto from the Properties and shall not thereafter make any use
     whatsoever of such names,  signs, and logos.  After Closing and as to those
     Properties  Buyer has taken over as operator,  Seller reserves the right of
     access to confirm that Buyer has removed  Seller's name,  signs, and logos.
     If Seller is forced to remove its name,  signs, and logos because Buyer has
     failed to do so, Seller shall charge its costs to Buyer and Buyer shall pay
     Seller's invoice within fifteen (15) days of receipt.

     (m) Severability.  If any term or provision of this Agreement is determined
     to be invalid,  illegal,  or incapable of being enforced by any rule of law
     or public  policy,  all other  conditions  and provisions of this Agreement
     shall nevertheless  remain in full force and effect so long as the economic
     or legal substance of the transactions  contemplated hereby is not affected
     in any material fashion to either Buyer or Seller.  Upon such determination
     that any term or other provision is invalid, illegal, or incapable of being
     enforced,  Buyer and Seller  shall  negotiate  in good faith to modify this
     Agreement so as to effect the original  intent of the Parties as closely as
     possible  in  an  acceptable  manner  to  the  end  that  the  transactions
     contemplated hereby are fulfilled to the extent possible.

     (n) Reservation of Claims.  Seller reserves all rights to claims,  demands,
     cause of action,  and lawsuits  concerning  the  Properties  against  third
     parties that accrued before the Effective Date,  whether  discovered before
     or after the Effective Date, excluding any rights or claims associated with
     gas imbalances.

     (o) Buyer's Duty to Defend.  Where Buyer has agreed to  indemnify,  defend,
     and hold Seller harmless under this Agreement,  Seller, at its sole option,
     may  elect to (a)  manage  its own  defense,  in  which  event  Buyer  will
     reimburse Seller for all attorney's fees, court, and other costs reasonably
     incurred in defending a claim,  upon delivery to Buyer of invoices for such
     expenses; or (b) allow Buyer to be responsible for all aspects of defense.

     (p) Exhibits.  All exhibits  referenced  herein and attached  hereto are by
     reference incorporated into this Agreement.

     3. Revolving Loan Commitment.  Subject to the other terms and conditions of
this Agreement,  the Lender agrees to make advances to Borrower in the form of a
revolving  line of credit,  in an amount not to exceed the  principal  amount of
Five Million and No/100 Dollars  ($5,000,000.00)  (the "Revolving Loan") for the

behalf of Borrower  upon  request by Borrower as provided  herein,  (ii) funding
acquisitions of properties,  (iii) funding Borrower's  operations,  and (iv) for
such other purposes and in such amounts as may from time to time be requested by

Credit  (excluding  the  Aetna  LC and the TRC  LC)  and  the  principal  amount

nothing herein shall  constitute an agreement on the part of the Lender to grant
an extension hereof.

     4.  Revolving  Note.  Concurrently  with the  execution of this  Agreement,
Borrower shall execute and deliver to the Lender a certain  Promissory Note (the
"Revolving  Note") in the face  amount  of  $5,000,000.00  in the form  shown as
Exhibit "C" attached hereto and  incorporated  herein by reference,  which shall

to the Lender  pursuant to the  Revolving  Loan shall not exceed at any one time
the aggregate principal amount of $5,000,000.00. Nothing in this paragraph shall

     6. Loan Requests.  Each request of Borrower under this commitment  shall be
made in writing, by a person who is designated by Borrower in advance in writing
by appropriate action or resolution of Borrower, by Borrower's submission to the
Lender of a Loan Request ("Loan Request") in the form attached hereto as Exhibit

draw pursuant to the Revolving Note.

Credit  application  on a form provided by the Lender;  (ii) the fee  associated
therewith as provided in Section 2.10 hereof;  (iii) a written  specification of
any certifications required of the beneficiary to present any site draft; (iv) a

a written  specification  of any special  instructions;  and (vi) such other and
further information as the Lender may reasonably request.

     9.  Payment  of  Letter  of  Credit.  At the time any site  draft is timely
received by the Lender on a respective Letter of Credit issued hereunder, except
the Aetna LC and the TRC LC, the Lender shall  advance such funds on  Borrower's
behalf under the Revolving Note, provided however that the sum of (i) all issued
and  unexpired  Letters of Credit  (excluding  the Aetna LC and the TRC LC); and
(ii) the outstanding  principal amount due under the Revolving Note shall not at
any one time exceed the  principal  sum of  $5,000,000.00.  At the time any site
draft is timely received by the Lender on the Aetna LC or the TRC LC, the Lender

payable in lawful money of the United States of America at the principle  office
of the  Lender.  All such  payments  shall be made to Lender not later than 2:00
p.m.  Tulsa time on the date due and funds  received  after such hour on any day
shall be treated for all purposes of this  Agreement as having been  received on
the next succeeding full business day in Tulsa, Oklahoma.  Interest on the Notes
shall  be  calculated  for  the  actual  days  elapsed  on the  basis  of a year
containing 360 days. In any case where a payment of principal and/or interest on
the Notes or any part  thereof  is due on a day on which the  Lender is not open
for normal  banking  business,  the  Borrower  shall be  entitled  to delay such
payment until the next  succeeding  business day, but interest shall continue to
accrue until the payment is in fact made.

     12. Prepayment.  The Borrower may from time to time prepay the indebtedness
evidenced by the Term Note and/or the Revolving Note in whole or in part without
premium or penalty.  Any and all prepayments shall be applied and credited first
against  interest  then due and then to payment on the  principal  due under the
Term Note or Revolving Note, as the case may be.

     13.  Application  of Payments.  All payments of principal or interest under
the Term Note and the  Revolving  Note shall be  applied by the Lender  first to
accrued and unpaid interest, and second, to the outstanding principal balance of
the Term Note and Revolving Note, respectively.  Upon the occurrence of an Event
of Default  hereunder,  all  payments  thereafter  received by the Lender may be
applied by the Lender to the payment of principal  or interest  under either the
Term Note or the  Revolving  Note,  in the order or  manner  as the  Lender  may
determine in its sole discretion.

     14.  Offset.  In addition to and not in  limitation of all rights of offset
that the Lender may have under  applicable  law,  the Lender  after the maturity
date  under the Term Note or the  Revolving  Note,  whether by  acceleration  or
otherwise,  shall have the right to appropriate  and apply to the payment of the
Term  Note  and/or  the  Revolving  Note,  in the  manner  and  order  as may be
determined by the Lender in its sole discretion, any and all balances,  credits,
deposits,  accounts or monies of the  Borrower  then or  thereafter  held by the
Lender, which by reference herein are given to secure repayment of the Revolving
Note and the Term Note.

renewals  thereof,  including but not limited to the Term Note and the Revolving
Note.  Further,  as a condition precedent to the execution hereof by the Lender,
Borrower  shall  make,  execute and  deliver to the Lender  such  Amendments  to

funded  at any one time or in the  event  the  discounted  present  worth of the
Mortgaged Property,  as determined by the Lender, shall at any time be less than
$12,000,000.00,  Borrower  shall  make,  execute  and deliver to the Lender such
mortgages,  deeds of trust,  security agreements and such other documents as may
be  reasonably  requested by the Lender to grant to the Lender a first  priority

UCC financing and continuation  statements in such offices of public record,  or
shall cause to be promptly delivered to the Lender such statements, instruments,

interest granted therein  continuously  perfected in such Collateral,  and shall
execute and acknowledge and deliver or cause to be done, executed,  acknowledged
and  delivered,  all and every such further  act,  deed,  conveyance,  financing
statement, continuation statement, transfer and assurance as the Lender may from
time to time  request  for the  better  assuring,  conveying,  transferring  and
confirming   unto  the  Lender  such   collateral  that  is  now  and  hereafter
constituted.   Notwithstanding   the  above,  the  Lender  is  hereby  appointed
Borrower's  attorney-in-fact,  coupled with an interest,  to do, at the Lender's
option and at Borrower's expense,  all acts and things which the Lender may deem
necessary to perfect and continue  perfecting the security  interest referred to
or created by this  Agreement  and to protect  the  Lender's  lien and  security
interest in such Collateral.

     4. Release.  Borrower  acknowledges and agrees that the Lender may, without
the consent of Borrower and without  impairing or releasing the  obligations  of
Borrower under this Agreement,  the Notes or other Loan  Documents,  release any
Collateral  at any time  pledged  to  secure or  securing  the  Indebtedness  of
Borrower to the Lender.

     5. Indebtedness.  For purposes hereof,  Indebtedness shall mean and include
any and all: (i)  indebtedness,  obligations  and liabilities of the Borrower to

advances  and loans  made by the  Lender  to the  Borrower  and any  extensions,
renewals,  substitutions,  amendments and increases in amount thereof; (iii) all
reasonable  costs  and  expenses  paid  or  incurred  by the  Lender,  including
attorneys'  fees,  in  enforcing  or  attempting  to enforce  collection  of any
Indebtedness  and in  enforcing or realizing  upon or  attempting  to enforce or

                                       -9-

realize upon any collateral or security for any Indebtedness, including interest
on all sums so  expended  by the Lender  accruing  from the date upon which such
expenditures  are made until paid,  at an annual rate equal to the Default Rate;
(iv) all sums  expended  by the  Lender in curing  any Event of  Default  of the
Borrower  under the terms of this  Agreement,  the other Loan  Documents  or any
other  writing  evidencing  or securing the payment of the Notes  together  with
interest on all sums so expended by the Lender accruing from the date upon which
such  expenditures  are made until paid,  at an annual rate equal to the Default
Rate; and (v) all  "Indebtedness"  or "Secured  Indebtedness"  as said terms are
defined in each of the Loan Documents.

     6. Lien Survives Until Full  Repayment.  The Borrower  hereby  acknowledges
that  all of the  Collateral  is  granted  to the  Lender  as  security  for the
repayment of all of the Indebtedness.  Except as specifically limited herein, if
one or  more  Notes  is  paid in full  or  satisfied,  but  any  portion  of the
Indebtedness remains unsatisfied, the Lender may retain its security interest in
all of the Collateral until the remaining  Indebtedness is paid in full, even if
the value of the Collateral far exceeds the amount of Indebtedness outstanding.

     The Borrower covenants and agrees with the Lender that from the date hereof
and so  long  as  this  Agreement  is in  effect  (by  extension,  amendment  or
otherwise) and until payment in full of all  Indebtedness and the performance of
all other  obligations of the Borrower under this  Agreement,  unless the Lender
shall otherwise consent in writing:

     1.  Payment of Taxes and Claims.  The  Borrower  will pay and  discharge or
cause to be paid and  discharged all Taxes imposed upon the income or profits of
the Borrower or upon the  property,  real,  personal or mixed,  or upon any part
thereof,  belonging to the Borrower before the same shall be in default, and all
lawful claims for labor, rentals, materials and supplies which, if unpaid, might
become a Lien upon its property or any part thereof;  provided however, that the
Borrower  shall  not be  required  to pay and  discharge  or cause to be paid or
discharged  any such Tax,  assessment  or claim so long as the validity  thereof
shall be contested in good faith by appropriate  proceedings,  and adequate book

subject to execution.

franchises  and will continue to conduct and operate its business  substantially
as being conducted and operated  presently.  The Borrower will become and remain
qualified  to  conduct  business  in each  jurisdiction  where the nature of the
business  or   ownership   of  property  by  the   Borrower   may  require  such
qualification.

     3.  Preservation  of  Property.  The Borrower  will at all times  maintain,
preserve and protect all  franchises  and trade names and keep all the remainder
of its  properties  which  are used or  useful in the  conduct  of its  business
whether  owned in fee or  otherwise,  or leased,  in good  repair and  operating
condition;  from time to time make, or cause to be made,  all needful and proper
repairs,  renewals,  replacements,  betterments and improvements thereto so that
the  business   carried  on  in   connection   therewith  may  be  properly  and
advantageously  conducted at all times;  and comply with all material  leases to
which it is a party or under  which it  occupies  property  so as to prevent any
material loss or forfeiture thereunder.

     4. Insurance. The Borrower will keep or cause to be kept adequately insured
by financially sound and reputable insurers its equipment,  motor vehicles,  and
all other property of a character  usually insured by businesses  engaged in the
same or similar businesses,  including the Collateral. Upon demand by the Lender
any insurance  policies covering the Collateral shall be endorsed to provide for
payment of losses to the Lender as its interest may appear, to provide that such
policies may not be  canceled,  reduced or affected in any manner for any reason
without  thirty days prior  notice to the  Lender,  and to provide for any other
matters which the Lender may reasonably  require;  and such  insurance  shall be
against fire,  casualty and any other hazards normally insured against and shall
be in the amount of the full value (less a reasonable  deductible  not to exceed
amounts  customary  in  the  industry  for  similarly  situated  businesses  and
properties)  of the property  insured.  The Borrower shall at all times maintain
adequate insurance against damage to persons or property,  which insurance shall
be by  financially  sound and reputable  insurers and shall  without  limitation
provide the following  coverages:  comprehensive  general  liability  (including

substances  and  pollutants,  damage caused by explosion,  damage to underground
minerals or resources,  broad form property damage coverage, broad form coverage

requirements  of all  applicable  Laws and orders of any Tribunal and obtain any
licenses,  permits, franchises or other governmental authorizations necessary to
the ownership of its properties or to the conduct of its business,  except where
failure to comply would not  materially  impair the ability of Borrower to carry
on its business substantially as now conducted.

     6. Financial Statements and Reports.

          (a) Quarterly  Financial  Statements.  The Borrower  shall  maintain a
     standard  system of  accounting  and shall furnish to the Lender as soon as

     behalf,  by the President or the chief financial officer of the Borrower to
     have been  prepared in  accordance  with GAAP  consistently  applied and to
     fairly present the financial condition of the Borrower for such period, and
     shall include at least a balance sheet as at the end of such period,  and a

          accountants that in the course of the audit necessary for their report
          on the  financial  statements,  they have obtained no knowledge of any
          Event of Default or  Default  as defined  herein,  or, if any Event of
          Default or Default existed or exists, specifying the nature and period
          of existence thereof;  provided,  however, that such accountants shall
          not be liable to the  Lender  by  reason  of their  failure  to obtain
          knowledge  of any such Event of Default or Default  which would not be
          disclosed  in the  course of an audit  conducted  in  accordance  with
          generally accepted auditing standards.

     Such annual  financial  statement shall also be accompanied by a no-default
     certificate signed by Borrower's chief executive officer or chief financial
     officer.  The  "no-default"  certificate  required  in this  paragraph  and
     paragraph 5.6(a) above,  shall in each instance certify that to the best of
     the chief executive officer or chief financial officer's knowledge (i) that
     the  information  shown or reflected on the  financial  statements  for the
     Borrower is true and correct as of the date of such  statements;  (ii) that
     there has been no change  in the  financial  condition  of  Borrower  which
     significantly impairs the security of the Lender or significantly increases
     the Lender's  risk or affects the  Borrower's  ability to satisfy its debts
     and  obligations  in a timely  manner;  (iii) that no default has  occurred
     under this Agreement or any of the other Loan Documents;  and (iv) that all
     conditions, covenants, representations and warranties, as set forth in this
     Agreement and the other Loan  Documents are true and correct as of the date
     of such no-default certificate.

          (c) Special  Auditing  Reports.  Promptly  upon receipt  thereof,  the
     Borrower shall deliver to the Lender a copy of each report submitted to the
     Borrower by  Borrower's  independent  accountants  in  connection  with any
     annual,  interim or special  audit made by them of the books and records of
     the Borrower including, without limitation, any comment letter submitted by

Documents,  nor  fulfillment of nor compliance with their  respective  terms and
provisions  will conflict with, or result in a breach of, the terms,  conditions

any borrowing hereunder will be used to purchase or carry any margin stock or to
extend  credit to others for the purpose of  purchasing  or carrying  any margin
stock.  If  requested by the Lender,  the Borrower  will furnish to the Lender a
statement  in  conformity  with the  requirements  of Federal  Reserve  Form U-1
referred to in Regulation U, to the foregoing effect. The Borrower has not taken
nor will it take any action  which  might cause this  Agreement  or the Notes to
violate any  regulation of the Board of Governors of the Federal  Reserve System
(including  but not  limited to  Regulations  G, T, U and X) or to  violate  any
securities laws, state or federal,  in each case as in effect now or as the same
may hereafter be in effect.

results  or  could  result  in  the  Borrower's  noncompliance  with  any  Laws,
ordinances,  rules,  regulations and other legal requirements  applicable to the
Borrower,  or (ii) could or would have a material adverse effect on the business
or condition, financial or otherwise, of the Borrower.

     9.  Possession of  Franchises,  Licenses,  Etc. The Borrower  possesses all
material franchises,  certificates,  licenses,  permits and other authorizations
from governmental  political subdivisions or regulatory  authorities,  free from
burdensome  restrictions,  that are  necessary in any  material  respect for the
ownership,  maintenance  and  operation of its  properties  and assets,  and the
Borrower is not in violation of any thereof in any material respect.

     10. Leases. The Borrower enjoys peaceful and undisturbed  possession of all
leases necessary in any material respect for the operation of its properties and
assets, none of which contains any unusual or burdensome  provisions which might

books of the Borrower, including interest and penalties. No income tax liability

     13.  Disclosure.  Neither  this  Agreement  nor any other Loan  Document or
writing  furnished to the Lender by or on behalf of the  Borrower in  connection
herewith  contains  any untrue  statement  of a  material  fact nor do such Loan
Documents  and  writings,  taken  as a  whole,  omit to  state a  material  fact
necessary  in order to make the  statements  contained  herein and  therein  not
misleading.  There is no fact known to the  Borrower  and not  reflected  in the
financial  statements provided to the Lender which materially  adversely affects
or in the future may  materially  adversely  affect the business,  property,  or
assets,  or financial  condition of the Borrower which has not been set forth in
this  Agreement,  in the Loan Documents or in other  documents  furnished to the
Lender by or on behalf of the  Borrower  prior to the date hereof in  connection
with the transactions contemplated hereby.

     presence  or use of  which  on the  Mortgaged  Property  is  prohibited  or
     regulated by any Governmental  Requirements (as hereinafter  defined);  and
     (d) any other substance  which by any  Governmental  Requirements  requires
     special   handling  or  notification   of  any  federal,   state  or  local
     governmental entity in its collection, storage, treatment, or disposal. For
     purposes   herein   "Governmental   Requirements"   shall  mean  all  laws,
     ordinances,  statutes, codes, rules, regulations, orders and decrees of the
     United  States,  the state,  the county,  the city, or any other  political

     this Agreement) emanating from the Mortgaged Property.

     16.  Issuance of Capital  Stock.  All of the shares of the capital stock of
the Borrower have been duly issued and are fully paid and non-assessable. All of
the  outstanding  shares of capital  stock of the  Borrower  were issued under a

amended, and all applicable state securities Laws, and do not require compliance
with the Trust Indenture Act of 1939.

     18.  Investment  Company  Act  Representation.   The  Borrower  is  not  an

as amended (the "Code"),  of which the Borrower is a part. Each Plan established
or  maintained  by the Borrower is in material  compliance  with the  applicable
provisions  of ERISA,  and the Borrower has filed all reports  required by ERISA
and the Code to be filed with  respect to each Plan.  The  Borrower  has met all
requirements  with respect to funding Plans imposed by ERISA or the Code.  Since
the  effective  date of Title IV of ERISA  there have not been any nor are there
now  existing  any  events  or  conditions  that  would  permit  any  Plan to be
terminated under circumstances which would cause the lien provided under Section

                                      -20-

<PAGE>



4068 of ERISA to attach to the assets of the Borrower.  The value of each Plan's
benefits  guaranteed  under Title IV of ERISA on the date hereof does not exceed
the value of such Plan's assets allocable to such benefits on the date hereof.

marshalling  of assets or Collateral  for repayment of the  Indebtedness  in the
event of the  occurrence  of any Default or Event of Default  hereunder or under

realize or foreclose  upon any of the  Collateral  or any portion as part of the
Collateral in any order including but not limited to the property  encumbered by
the  Mortgage.  The terms of this  paragraph  shall  survive  any release of the
Mortgage and shall remain in effect  between  Lender and Borrower as long as any
Indebtedness exists in any form.

     3. Survival of Agreements. All covenants,  agreements,  representations and

shall  never be  entitled  to  receive,  collect or apply,  as  interest  on the
Indebtedness,  any amount in excess of the maximum rate of interest permitted to
be charged by the Lender by  applicable  Law, and, in the event the Lender shall
ever receive,  collect or apply, as interest, any such excess, such amount which
would be excessive  interest shall be applied to other  Indebtedness and then to
the reduction of  principal;  and, if all other  Indebtedness  and principal are
paid in full, then any remaining excess shall forthwith be paid to the Borrower.

     7. No Waiver;  Cumulative Remedies. No failure to exercise, and no delay in
exercising on the part of the Lender, any right, power or privilege hereunder or
under any other Loan  Document or  applicable  Law shall  preclude  any other or
further exercise thereof or the exercise of any other right,  power or privilege
of the Lender.  The rights and remedies  herein  provided are cumulative and not
exclusive of any other rights or remedies provided by any other instrument or by
law. No amendment,  modification or waiver of any provision of this Agreement or
any other Loan Document  shall be effective  unless the same shall be in writing
and signed by the  Lender.  No notice to or demand on the  Borrower  in any case
shall  entitle the Borrower to any other or further  notice or demand in similar
or other circumstances.

     8.  Costs.  The  Borrower  agrees to pay to the Lender on demand all costs,
fees and  expenses  (including  without  limitation  attorneys'  fees and  legal
expenses)  incurred or accrued by the Lender in connection with the preparation,
execution, delivery, filing, recording and administration of this Agreement, the
Security  Instruments  and the other Loan Documents,  or any amendment,  waiver,
consent  or  modification  thereto  or  thereof,  or  any  enforcement  thereof,

closed and regardless of whether or not any sums are advanced to the Borrower by
the Lender.

     9. Participation.  The Borrower recognizes and acknowledges that the Lender
may  sell  participating  interests  in one or more of the  Notes to one or more
financial  institutions  (the  "Participants").  Upon  receipt  of notice of the
identity and address of each  Participant,  the Borrower shall thereafter supply
each  Participant  with the same  information  and reports  communicated  to the
Lender,  whether  written  or oral.  Each  Participant  shall  own an  undivided
interest in the  applicable  Note and shall have the same rights and remedies as
granted to the Lender hereunder with respect to said Participant's participating
interest in said Note. The Borrower hereby  acknowledges  that each  Participant
shall  be  deemed  a  holder  of  the  applicable  Note  to  the  extent  of its
participation,  and the Borrower  hereby waives its right, if any, to offset any
amounts owing to the Borrower from the Lender against any Participant's  portion
of the applicable Note.
