forth in Schedule  2.3, and (ii)  obligated to bear the  percentage of the costs
and expenses relating to the maintenance, development and operation of the Lease

Buyer in accordance  with the terms of this Agreement,  and including  copies of
relevant  portions of any title opinions or other title information on which the

alleged  Title  Defect is  discovered,  but in no event later than 12:00 noon on
April 12, 1996 ; provided  that Buyer shall  notify BSHP on or before 12:00 noon
on March 1, 1996 of any alleged  Title Defect  directly  related to the Escobeda
Title Matter.  Any matters that may otherwise  constitute Title Defects but that
are not  specifically  raised in a Title Defect Notice  delivered prior to 12:00
noon on April 12, 1996 shall be deemed to have been  waived by Buyer,  except to
the extent that any Title Defect constitutes a breach of the special warranty of
title contained



                                      -12-








in the  Assignment  delivered  by Working  Interest  Owners at  Closing  and the
warranty   of  title  made  by  Operator   pursuant   to  Section   5.3(e)(vii).
Notwithstanding the foregoing, any title defect or irregularity directly related
to the Escobeda Title Matter that is not  specifically  raised in a Title Defect
Notice delivered by Buyer to BSHP on or before 12:00 noon on March 1, 1996 shall
be deemed waived by Buyer. Operator or any Working Interest Owner shall have the
option, but not the obligation, to attempt to cure any Title Defect.

         Section 4.4         Determination of and Remedies for Title Defects.

         (a)  Determination  of Title Defects and Defect Values.  Not later than
12:00 noon on April 26, 1996,  BSHP shall  notify  Buyer  whether it agrees with
Buyer's  claimed  Title  Defects  and/or the  proposed  defect  values  therefor
("Seller's  Response").  If BSHP does not agree with any  claimed  Title  Defect
and/or proposed  defect value  therefor,  then the parties shall enter into good
faith  negotiations  and shall  attempt to agree on such  matters.  The  parties
hereby  agree that there is no defect  value  with  respect to Title  Defects on
Subject Assets other than the Producing Properties.  If the parties cannot reach
agreement  concerning  either the  existence of a Title Defect or a defect value
within ten (10) days after  Buyer's  receipt of Seller's  Response,  upon either
party's  request,  the parties  shall  mutually  agree on and employ an attorney
experienced in title examination  ("Title  Consultant") to resolve all points of
disagreement  relating to Title Defects and defect  values;  provided,  however,
that if at any time any Title  Consultant  so chosen fails or refuses to perform
hereunder,  a new Title Consultant  shall be chosen by the parties.  The cost of
any such Title Consultant  shall be borne 50% by Sellers and 50% by Buyer.  Each
party shall  present a written  statement  of its  position on the Title  Defect
and/or  defect  value in question to the Title  Consultant  within five (5) days
after the Title  Consultant is selected,  and the Title  Consultant shall make a
determination  of all points of  disagreement  in accordance  with the terms and
conditions  of this  Agreement  within ten (10) business days of receipt of such
position  statements.  The  determination  by  the  Title  Consultant  shall  be
conclusive  and binding on the  parties,  and shall be  enforceable  against any
party in any court of competent  jurisdiction.  If  necessary,  the Closing Date
shall be deferred  until the Title  Consultant has made a  determination  of the
disputed  issues,  and all  subsequent  dates  and  required  activities  having
reference  to the  Closing  Date shall be  correspondingly  deferred;  provided,
however,  that, unless each Seller and Buyer mutually agree to the contrary, the
Closing  Date shall not be  deferred in any event for more than thirty (30) days
beyond the original Closing Date.

         (b) Remedies for Title Defect.  With respect to any Title Defect that a
Seller  elects  not to cure or that a  Seller  fails  to cure at or prior to the
Closing,  such Seller and Buyer shall  reduce the  Purchase  Price by the agreed
upon defect value of such Title Defect,  taking into consideration the Allocated
Value of the Producing  Property  subject to such Title  Defect,  the portion of
such  Producing  Property  subject to such Title  Defect and the legal effect of
such Title Defect on the Producing Property affected thereby; provided, however,
that if such Title  Defect is the result of a  discovery  by Buyer that  Working
Interest Owner



                                      -13-








or  Operator  owned,  as of the  Effective  Time,  a Net  Revenue  Interest in a
Producing  Property  that is less  than the Net  Revenue  Interest  set forth on
Schedule  2.3,  then Buyer and Seller agree that the  proportion of reduction to
the Purchase Price shall be equal to the product of the Allocated  Value of such
Producing Property and the percentage  reduction in such Net Revenue Interest as
a result of such Title Defect, and provided,  further,  that if the defect value
has been determined in accordance with Section  4.4(a),  the Title  Consultant's
determination will control.  Notwithstanding  anything to the contrary contained
herein, there shall be no reduction to the Purchase Price for Title Defects with
respect to any well on a Lease  Unit  pursuant  to the terms of  Section  4.4(b)
unless and until,  and then only to the extent that, the aggregate  value of all
adjustments  for Title  Defects  with  respect to such well on a Lease Unit,  on
well-by-well  basis,  exceeds  one-half of one percent  (1/2%) of the  Allocated
Value of such well on such Lease Unit.

         Section 4.5 Special Warranty of Title. The documents to be executed and
delivered by each Working  Interest  Owner to Buyer,  transferring  title to the
Purchased  Subject Assets as required hereby,  including the Assignment and Bill
of Sale attached hereto as Exhibit "E" (the  "Assignment"),  shall be subject to

approved  by BSHP  (which  approval  shall not be  unreasonably  withheld)  (the
"Environmental  Consultant") to have access to the Producing Properties for this
purpose at any reasonable time or times prior to April 12, 1996 (the "Assessment
Period").

         (b)  The  scope  of work  for the  Environmental  Assessment  shall  be
mutually  agreed  upon by Buyer and BSHP and the  agreement  of BSHP will not be
unreasonably withheld.


                                      -16-





         (c)  Buyer  shall  bear all  costs  associated  with the  Environmental
Assessment.  Working Interest Owner and Operator understand and acknowledge that
the   Environmental   Assessment  may  involve   subsurface   testing  of  soil,
groundwater,  and any surface water at the Producing  Properties and may involve
soil borings and the collection of groundwater samples by hydropunch,  geoprobe,
or similar  means,  but Buyer shall not  install  groundwater  monitoring  wells
without  the prior  consent of BSHP,  which  consent  shall not be  unreasonably
withheld. Buyer shall be responsible for disposing of any soil cuttings or other
waste  generated by this testing and shall restore the  Producing  Properties at
the end of the Assessment  Period to its condition  prior to the  performance of
the  Environmental  Assessment.  Buyer agrees to indemnify and hold each Working
Interest Owner and Operator harmless from any liability arising from the acts or
omissions of Buyer, its  representatives or the Environmental  Consultant during
the  performance  of the  Environmental  Assessment  WITHOUT REGARD TO THE SOLE,
PARTIAL  OR  CONCURRENT  NEGLIGENCE,  STRICT  LIABILITY,  OR OTHER  FAULT OF ANY
WORKING  INTEREST  OWNER  INDEMNITEE OR OPERATOR,  but in no event for the gross
negligence or willful  misconduct of any Working  Interest  Owner  Indemnitee or
Operator.  No  invasive  testing  or  excavation  other than soil  borings,  the
installation  of groundwater  wells,  and grab samples of surface soil,  surface
water,  or  sediment  approved  by BSHP  pursuant  to  Section  4.7(b)  shall be
undertaken without the prior consent of BSHP.

         (d)  Unless   otherwise   required  by  law,   Buyer  agrees  to  treat
confidentially all reports prepared for Buyer by its Environmental Consultant in
connection  with  the  performance  of the  Environmental  Assessment,  and  the
information contained in such reports  (collectively,  referred to herein as the
"Information").  The  Information  may  only be  used by  Buyer  or  Sellers  in
connection with the  transactions  contemplated by this Agreement.  In the event
that Buyer or its  representatives  become legally  compelled to disclose any of
the  Information,  Buyer shall provide Working  Interest Owner and Operator with
prompt  notice prior to any such  disclosure so that Working  Interest  Owner or
Operator,  if it  disagrees  with  this  obligation  to  disclose,  may  seek  a
protective  order or other  appropriate  remedy and/or waive compliance with any
applicable provisions of this Section 4.7(d).

         (e) Buyer  shall make the  Information  available  to Working  Interest
Owner and Operator and provide Working Interest Owner and Operator copies of the
Information without charge.

         (f) Working  Interest Owner and Operator shall have the right to have a
representative or representatives  accompany the Environmental Consultant at all
times  during the  Environmental  Assessment  and Buyer  agrees to give  Working
Interest  Owner and Operator  verbal  notice not more than 72 hours and not less
than 48 hours before any visits by the Environmental Consultant to the Producing
Properties. Buyer agrees to take and provide to Operator identical split samples
of all sampling done on the Producing Properties.

                                      -17-







          Section 4.8 Determination of Disqualifying Environmental Condition.

          (a) Notice of Environmental  Defects.  To establish the existence of a
Disqualifying Environmental Condition on a Subject Asset, Buyer shall deliver to
BSHP a notice (an  "Environmental  Defect Notice") as soon as practicable  after
discovery of such Disqualifying  Environmental  Condition and in any event prior
to 12:00 noon on April 12,  1996  asserting  the  existence  of a  Disqualifying
Environmental  Condition and including (i) the  Environmental  Assessment  which
must contain a conclusion that a Disqualifying  Environmental  Condition exists,
and which  conclusion  must be  reasonably  substantiated  by the results of the
investigation conducted by the Environmental  Consultant and (ii) a bid from the
Environmental Consultant and another qualified environmental consulting firm for
the  correction of the  Disqualifying  Environmental  Condition in the most cost
effective manner reasonably  available.  As a minimum standard for acceptance by
Working Interest Owner and Operator, such Environmental  Assessment must reflect
that the  Environmental  Consultant  performed  sufficient  invasive testing and
analytical   work  to  delineate   reasonably  the  nature  and  extent  of  the
Disqualifying  Environmental Condition and is further required to contain a site
plan showing the location of all  sampling  events,  boring logs and other field
notes  describing  the  sampling  methods  utilized  and  the  field  conditions
observed, chain-of- custody documentation, laboratory reports, and copies of two
bids for corrective work.

         (b) Seller's Reply to Defect  Notice.  On or before 12:00 noon on April
26, 1996,  the affected  Working  Interest  Owner and/or  Operator shall provide
Buyer with written  notice as to whether it  acknowledges  the existence of each
Disqualifying  Environmental  Condition  asserted  by Buyer in an  Environmental
Defect Notice delivered  pursuant to the terms hereof.  If such Working Interest
Owner or Operator  does not provide  Buyer on or before said time with a written
notice that Working  Interest  Owner or Operator  rejects the  conclusion in the
Environmental  Assessment as to the existence of a  Disqualifying  Environmental
Condition,  such  Working  Interest  Owner or  Operator  shall be deemed to have
acknowledged the existence of a Disqualifying Environmental Condition.

         (c) Buyer's Rights of Acceptance or Appeal. If a Working Interest Owner
or Operator timely rejects the conclusions in the Environmental Assessment, then
Buyer shall have five (5) days after the receipt of this rejection to appeal the
rejection by providing such Working  Interest Owner or Operator within this five
day period  with a written  notice of its  appeal.  If Buyer does not timely and
properly  appeal  within  this  time  period,  Buyer  shall  be  deemed  to have
acknowledged  that no Disqualifying  Environmental  Condition  exists.  If Buyer
accepts or is deemed to accept  that no  Disqualifying  Environmental  Condition
exists, then the parties will proceed to Closing. If Buyer timely appeals, then,
at the sole cost of the unsuccessful party in the appeal process, Buyer and such
Working  Interest Owner or Operator shall each select a consulting firm and then
the two consulting  firms shall mutually agree upon a third firm. The third firm
shall  make  a  determination   whether  the  conclusion  in  the  Environmental
Assessment that a Disqualifying Environmental Condition exists is



                                      -18-








correct and is  supported  by an  investigation  conducted  in  accordance  with
industry-accepted  standards.  The  determination  of the third  consulting firm
shall be final and binding upon Buyer and a Working  Interest  Owner or Operator
as to the  existence  of a  Disqualifying  Environmental  Condition.  The  third
consulting  firm shall also  estimate the cost of correcting  the  Disqualifying
Environmental  Condition in the most cost effective manner reasonably available.
Buyer and the applicable  Working  Interest  Owner or Operator shall  reasonably
cooperate in the appeal process which shall be completed within thirty (30) days
after Buyer gives  Working  Interest  Owner or  Operator  written  notice of its
appeal.  If any  party  fails to  cooperate  in the  appeal  process  or the two
appointed  consultants  cannot agree upon a third consultant,  then either party
may petition the United States District Judge for the Southern District of Texas
then senior in service to designate a qualified and experienced consulting firm.

          Section 4.9 Remedies for a Disqualifying Environmental Condition.

          (a)  With  respect  to  all  Disqualifying   Environmental  Conditions
established pursuant to Section 4.8, the following provisions shall apply.

                  (i) If the  Environmental  Defect  Value of all  Disqualifying
Environmental  Conditions  associated  with a  Producing  Property  exceeds  the
Allocated  Value of such  Producing  Property,  Buyer may elect to exclude  such
Producing Property from this transaction and treat such Producing Property as an
Excluded Asset in which event the Purchase  Price shall be adjusted  downward by
the Allocated Value of such Producing Property.

                  (ii) If the  Environmental  Defect Value of all  Disqualifying
Environmental Conditions associated with a Producing Property exceeds 30% of the
Allocated Value of such Producing  Property,  Working Interest Owner or Operator
may elect to exclude such  Producing  Property from this  transaction  and treat
such  Producing  Property as an Excluded Asset in which event the Purchase Price
shall be adjusted downward by the Allocated Value of such Producing Property.

                  (iii)  If the  Aggregate  Environmental  Defect  Value  of all
Disqualifying  Environmental  Conditions on Producing  Properties not treated as
Excluded Assets pursuant to Section 4.9(a)(i) and (ii) does not exceed $250,000,
Buyer  alone  shall  pay and be  responsible  for the costs of  correcting  such
Disqualifying Environmental Conditions.

                  (iv)  If  the  Aggregate  Environmental  Defect  Value  of all
Disqualifying  Environmental  Conditions on Producing  Properties not treated as
Excluded Assets pursuant to Section 4.9(a)(i) and (ii) exceeds  $250,000,  Buyer
shall  pay  and  be  responsible   for  the  first  $250,000  of  the  Aggregate
Environmental Defect Value and Working Interest Owner and



                                      -19-








Operator shall pay and be  responsible  for the balance of such amount (but such
payments shall not be included as a part of the Closing Working Capital).

          (b) Operator shall have the right,  but not the obligation,  on behalf
of itself and any  affected  Working  Interest  Owner to cure any  Disqualifying
Environmental  Condition prior to Closing. The Environmental Defect Value of any
Disqualifying  Environmental  Condition  cured by  Operator in  accordance  with
Section  4.10 prior to Closing  shall be  applied  against  the amount for which
Working Interest Owner and Operator are responsible under Section 4.9(a)(iv).

         (c) If the Operator  does not correct any  Disqualifying  Environmental
Defect prior to the  Closing,  then Buyer shall  proceed  with due  diligence in
accordance  with industry  accepted  practices  after the Closing to correct any
Disqualifying Environmental Conditions in accordance with Section 4.10 for which
it is  responsible  under  Sections  4.9(a)(iii)  and (iv). At the Closing,  the
Purchase  Price  shall be adjusted  downward by the amount of the  Environmental
Defect Value for which Working Interest Owner and Operator are responsible under
Section 4.9(a)(iii), less any credit to which they are entitled under 4.9(b).

         Section 4.10 Correction of a Disqualifying  Environmental Condition. To
correct  a  Disqualifying  Environmental  Condition  involving  a  violation  of
Environmental  Laws, the party  responsible  for  correcting  the  Disqualifying
Environmental  Condition  under the provisions of Sections  4.9(b) and (c) shall
cure  the  violation  and  provide  reasonable   evidence  to  the  other  party
substantiating  that the  violation has been cured.  To correct a  Disqualifying
Environmental  Condition involving Regulated  Substances,  the responsible party
shall perform the type of remediation  that a prudent operator would perform and
shall  provide  the other  party with  written  assurance  from the  appropriate
Governmental Authority that no further action is required in connection with the
Regulated  Substances,  or if no such written assurance is customarily  obtained
under normal procedures  observed by prudent  operators,  a certification from a
qualified  consultant  that the  appropriate  remediation has been performed and
that no further response is required under applicable Environmental Laws.

         (d) Brokers.  No broker or finder has acted for or on behalf of Working
Interest  Owner  in  connection   with  this   Agreement  or  the   transactions
contemplated by this Agreement. No broker or finder is entitled to any brokerage
or  finder's  fee,  or to  any  commission,  based  in any  way  on  agreements,
arrangements or  understandings  made by or on behalf of Working  Interest Owner
for which Buyer has or will have any  liabilities or obligations  (contingent or
otherwise).




                                      -21-








          (e) Bankruptcy. There are no bankruptcy,  reorganization,  arrangement
or similar proceedings  pending, or, to the knowledge of Working Interest Owner,
threatened against Working Interest Owner.

          (f) Suits.  Except for Black Stone Oil Company v. C.C.  Lilley,  Inc.,
there is no suit,  action,  claim,  investigation  or  inquiry  by any person or
entity  or by any  administrative  agency  or  governmental  body and no  legal,
administrative or arbitration proceeding pending or, to the knowledge of Working
Interest  Owner,  threatened  against  Working  Interest  Owner or the Purchased
Subject Assets which, if decided  adversely to the interest of Working  Interest
Owner, would reasonably be expected to have a material adverse affect on the use
or value of the Purchased Subject Assets.

          (g) No  Defaults.  Working  Interest  Owner  has no  knowledge  of any
default with respect to the Producing  Properties  that has not been remedied or
waived and that would have a material adverse effect,  and to the best of BSHP's
knowledge,  the Producing  Properties  are being held,  developed,  operated and
produced  substantially  in  compliance  with the  terms and  conditions  of the
Contracts and all other applicable agreements.

          (h)  Royalties.  All rentals,  royalties  and other  payments due with
respect to the Producing  Properties have been properly and timely paid,  except
those  amounts  in  suspense,  and,  to the  best of  Working  Interest  Owner's
knowledge,  all conditions  necessary to keep the Producing Properties in effect
have been duly performed.

          (i) Taxes. All ad valorem, property, production, severance, excise and
similar  taxes and  assessments  based on or  measured by the  ownership  of the
Purchased  Subject  Assets or the production of  Hydrocarbons  or the receipt of
proceeds  therefrom  on the  Purchased  Subject  Assets that have become due and
payable have been properly and timely paid.

          (j) Non-Resident  Status.  Working Interest Owner is not a nonresident
alien of the United States.

          (k)  Investment.  Prior  to  entering  into  this  Agreement,  Working
Interest  Owner  was  advised  by and  relied  on its own  legal,  tax and other
professional counsel concerning this Agreement, the Purchased Subject Assets and
the value thereof.  Working Interest Owner  acknowledges  that Buyer is entering
into other purchase  agreements with other owners of interests in certain of the
properties  which  are  covered  by this  Agreement,  and  that  the  terms  and
conditions of such  agreements may differ from those  contained  herein and from
those contained among the various other agreements.

          (l) Laws and Regulations.  Except as set forth on Schedule 5.1(l),  to
the best of Working Interest Owner's  knowledge,  the Producing  Properties have
been and currently are



                                      -22-








being  operated  in  compliance,  with all laws,  regulations  and orders of all
Governmental Authorities, except where the failure to so comply would not have a
material  adverse affect on the business  operations,  financial  condition,  or
results of operations of Working Interest Owner or of the Producing Properties.

          (m)  Prepayments  and Gas Balancing.  To the best of Working  Interest
Owner's  knowledge,  it is  receiving on a current  basis the payments  required
under  gas  contracts  or  other  contractual  arrangements  for  the  delivery,
transportation  or sale of natural gas from the  Producing  Properties.  Working
Interest Owner is not obligated under any prepayment arrangement,  "take-or-pay"
contract,  production payment agreement,  well head or plant balancing agreement
or other arrangement to deliver Hydrocarbons at some future time without then or
thereafter  receiving full payment therefor,  and as of the Effective Time there
are no material  "pipeline" or other  imbalances with respect to any contract or
agreement  which would require  settlement by cash from Working  Interest  Owner
sometime in the future.

          (n) Calls on Production. Except as provided in the Contracts listed in
Exhibit A and lessors' rights to take production in kind, no person has any call
upon,  option to  purchase,  right of refusal or similar  unexecuted  right with
respect to the  purchase  of Working  Interest  Owner's  portion of  Hydrocarbon
production from the Producing Properties.

          (o)  Wells  and  Units.  To  the  best  of  Working  Interest  Owner's
knowledge,  every well  comprising a part of the Producing  Properties  has been
drilled and completed within the applicable lease or within the limits otherwise
permitted  by  contract,  pooling or unit  agreement  and by law. To the best of
Working Interest Owner's  knowledge,  no well comprising a part of the Producing
Properties is subject to penalties on allowables  because of any  overproduction
permitted by applicable laws, rules,  regulations or permits,  orders or decrees
of any Governmental Authority, which would prevent such well from being entitled
to its full, legal and regular allowable, from and after the Effective Time.

          (p)  Consents.  Except as provided  in the  instruments  described  on
Schedule  5.1(p),  no consent,  authorization  or approval of any third party is
required under any material agreement to which Working Interest Owner is a party
or to which its interest in the Subject  Assets is bound for the  execution  and
delivery of this Agreement by Working  Interest Owner or the  performance of its
obligations hereunder.

          (q) Governmental Approvals. Neither the execution and delivery of this
Agreement by Working  Interest  Owner nor the  performance  by Working  Interest
Owner of its obligations  hereunder will require any consent,  authorization  or
approval  of, or waiver or  exemption  by,  or  filing  with or notice  to,  any
governmental  agency,  instrumentality  or authority  under any provision of law
applicable to Working Interest Owner, except for (i)



                                      -23-








applicable  filings under the HSR Act, (ii) those required under the instruments
described in Schedule 5.1(p) and (iii) those that are customarily obtained after
the Closing.

         (r) Accuracy of Information Furnished.  To the best of Working Interest
Owner's knowledge, all Contracts with respect to the Producing Properties can be
found either of record in Polk County, Texas or in, or referenced in, Operator's
or  BSHP's  files.  To the  best of  Working  Interest  Owner's  knowledge,  all
Contracts located in Operator's or BSHP's files are true,  accurate and complete
copies.

laws.

Shares set forth opposite his name on Schedule II, free and clear of any and all
liens,  security  interests,  encumbrances,  charges,  adverse claims,  options,

has the  right to vote  such  shares on any  matters  as to which any  shares of
common  stock of  Operator  are  entitled to vote under the laws of the State of
Texas and Operator's  articles of incorporation and bylaws, free of any right in
any other person.

         (d) No Conflicts. To the best of Selling Stockholder's  knowledge,  the
execution and delivery of this  Agreement by Selling  Stockholder  does not, and
the  performance of its obligations  hereunder will not,  constitute a violation
of, conflict with, or result in a default under,  any agreement or instrument to
which Selling  Stockholder is a party or by which Selling  Stockholder is bound,
or any judgment,  decree or order applicable to Selling  Stockholder which would
have a material adverse effect on Selling Stockholder or its Purchased Shares.



                                      -24-









         (e) Approvals. To the best of Selling Stockholder's  knowledge,  except

Agreement by Selling  Stockholder nor the performance by Selling  Stockholder of
its obligations  hereunder will require any consent,  authorization  or approval
of, or waiver or  exemption  by, or filing  with or notice to, any  governmental
agency,  instrumentality  or authority  under any provision of law applicable to
Selling Stockholder or other third party.

         (f) S  Corporation  Status.  Selling  Stockholder  is not a nonresident
alien of the United States and Selling  Stockholder is either an individual or a
"qualified  subchapter S trust"  within the meaning of sections  1361(c)(2)  and
1361(d) of the Code.

         (g) Brokers.  No broker or finder has acted for or on behalf of Selling
Stockholder in connection with this Agreement or the  transactions  contemplated
by this Agreement.  No broker or finder is entitled to any brokerage or finder's
fee,  or to any  commission,  based in any way on  agreements,  arrangements  or
understandings  made by or on behalf of Selling  Stockholder for which Buyer has
or will have any liabilities or obligations (contingent or otherwise).

         (h)  Investment.   Prior  to  entering  into  this  Agreement,  Selling
Stockholder  was  advised  by and  relied  on  its  own  legal,  tax  and  other
professional counsel concerning this Agreement, the Subject Assets and the value
thereof.  Selling  Stockholder  acknowledges  that Buyer is entering  into other
purchase  agreements with other owners of interests in certain of the properties
which are covered by this  Agreement,  and that the terms and conditions of such
agreements may differ from those contained herein and from those contained among
the various other agreements.

         Section  5.3  Representations  and  Warranties  of  Operator.  Operator

material  adverse  effect on its  business,  prospects,  financial  condition or
results of operations. Operator is qualified or licensed to transact business as
a foreign corporation in Texas and Louisiana.

obligating  Operator  to  issue  any  shares  of  capital  stock  or  any  other
securities.  Other than the articles of incorporation  and bylaws,  there are no
agreements or instruments  among,  or otherwise  governing the relations of, the
shareholders of Operator.

complete copy of the compiled balance sheet of Operator at December 31, 1994 and
the related income  statement and statement of retained  earnings for the period
then ended and the  unaudited  balance sheet at October 31, 1995 and the related
income  statement and  statement of retained  earnings for the period then ended
(collectively,  the "Financial Statements").  The Financial Statements have been
prepared in accordance with GAAP, and present fairly the financial  condition of
Operator at and as of such dates.

         (e)      Operator Subject Assets.

                  (i) No Defaults. Operator has no knowledge of any default with
respect  to any  Producing  Properties,  the  Contracts  or any  other  material
agreement, which has not been remedied or waived and which would have a material
adverse  effect  on such  Producing  Properties,  and to the best of  Operator's
knowledge,  the Producing  Properties  are being held,  developed,  operated and
produced  substantially  in  compliance  with the  terms and  conditions  of the
Contracts and all other applicable agreements.

                  (ii)  Royalties.  To the  best of  Operator's  knowledge,  all
rentals,  royalties  and  other  payments  due  with  respect  to the  Producing
Properties have been properly and timely paid, except those amounts in suspense,
and, all  conditions  necessary to keep the Producing  Properties in effect have
been duly performed.

                  (iii) Prepayments and Gas Balancing.  Operator is receiving on
a current basis the payments  required under gas contracts or other  contractual
arrangements  for the delivery,  transportation  or sale of natural gas from its
interest in the Producing Properties. There are no "take-or-pay" prepayments for
which an obligation exists to deliver gas after the Effective Time.  Operator is
not obligated under any material prepayment arrangement, "take-or-pay" contract,
production  payment agreement,  well head or plant balancing  agreement or other
arrangement  to  deliver  Hydrocarbons  at  some  future  time  without  then or
thereafter  receiving full payment therefor,  and as of the Effective Time there
are no material  "pipeline" or other  imbalances with respect to any contract or
agreement  which would  require  settlement by cash from Operator at sometime in
the future.

                  (iv) Calls on Production.  Except as provided in the Contracts
listed in Exhibit A and lessors'  rights to take  production  in kind, no person
has any call upon,  option to purchase,  right of refusal or similar  unexecuted
right with respect to the purchase of Hydrocarbon  production from the Producing
Properties.

                  (v)  Wells and  Units.  To the best of  Operator's  knowledge,
every well  comprising a part of the Producing  Properties  has been drilled and
completed within the applicable  lease or within the limits otherwise  permitted
by contract,  pooling or unit  agreement  and by law. To the best of  Operator's
knowledge,  no well comprising a part of the Producing  Properties is subject to
penalties  on  allowables  after the date hereof  because of any  overproduction
permitted by applicable laws, rules,  regulations or permits,  orders or decrees
of any  governmental  body or agency,  which would  prevent such well from being
entitled  to its full,  legal  and  regular  allowable,  from and after the date
hereof, as prescribed by any court or governmental body or agency.

                  (vi) Taxes. All ad valorem, property,  production,  severance,
excise and similar taxes and  assessments  based on or measured by the ownership
of the Operator  Subject Assets or the production of Hydrocarbons or the receipt
of proceeds  therefrom on the Operator  Subject  Assets that have become due and
payable have been properly and timely paid.

                  (vii)  Title.  At  the  Closing,  Operator's  interest  in the
Operator Subject Assets is free and clear of all claims,  liens and encumbrances
created by, through or under Operator, except for the Existing Encumbrances.




                                      -27-








          (f) Non-Resident  Status.  Operator is not a nonresident  alien of the
United States.


          (g) Additional Contracts.  Except with respect to the Excluded Assets,
the Contracts listed on Exhibit A and those having a term of 90 days or less (or
terminable  on  notice of 90 days or less),  there  are no  material  contracts,
arrangements  and  commitments  (whether oral or written) to which Operator is a
party or by which any of  Operator's  assets or  business  are bound  including,
without limitation,  contracts,  arrangements or commitments which relate to (1)
the sale, lease or other  disposition by Operator of all or any substantial part
of the business or assets of Operator  (otherwise than in the ordinary course of
business),  (2) the  purchase or lease by Operator  of a  substantial  amount of
assets  (otherwise than in the ordinary  course of business),  (3) the supply by
Operator  of any  customer's  requirements  for any oil,  gas or other  goods or
services or the  purchase by Operator of its  requirements  for any item or of a
vendor's output of any item, in each case in which the aggregate annual payments
to Operator by such customers or by Operator to such vendor exceed $25,000,  (4)
lending or advancing  funds by Operator,  (5) borrowing of funds or  guarantying
the  borrowing of funds by any other person,  whether under an indenture,  note,
loan agreement or otherwise, (6) any transaction or matter with any affiliate of
Operator,  (7)  noncompetition  or employment,  or (8) any other matter which is
material to the  business,  assets or  operations  of  Operator  (other than any
Contracts) ("Additional Contracts").

          (h) No  Violations.  The execution  and delivery of this  Agreement by
Operator and the consummation of the transactions  contemplated  hereby will not
(a) violate any  provision  of its  articles of  incorporation  or bylaws or (b)
violate any statute, rule, regulation,  judgment,  order or decree of any public
body or authority by which Operator or its properties or assets are bound.

          (i) Litigation and Related Matters. Except for Black Stone Oil Company
v. C.C. Lilley, Inc., there are no actions, suits, proceedings or investigations
pending against  Operator or, to the knowledge of Operator,  threatened  against
Operator,  Operator's business or any property or rights of Operator,  at law or
in  equity,  before  or by any  court  or  federal,  state,  municipal  or other
governmental department,  commission,  board, bureau, agency or instrumentality,
domestic or foreign  ("Agencies").  Operator  is not  subject to any  continuing
court or Agency order, writ, injunction or decree applicable specifically to the
business,  operations  or assets of Operator or employees  of  Operator,  nor in
default with respect to any order,  writ,  injunction  or decree of any court or
Agency with respect to its assets, business,  operations or employees. There are
no worker's  compensation  claims  outstanding  against  Operator as of the date
hereof.

                  (ii)  Operator  has  filed  all  income  tax  returns  or  tax
information  returns  required  to be filed by it and all returns of other Taxes
required  to be filed by it and has paid or  provided  for all Taxes shown to be

outstanding  agreements or waivers extending the applicable statutory periods of
limitation  for such Taxes for any  period.  All Taxes which  Operator  has been
required to collect or withhold have been duly withheld or collected and, to the
extent required,  have been paid to the proper taxing authority except where the
failure to file such returns or pay such Taxes would not have a material adverse
effect on the Operator or its business. No federal income Taxes will be assessed
on or after the Closing  Date against  Operator for any tax period  ending on or

         (k) Patents, Trademarks.  Except for geophysical and software licences,

thereby will (i) entitle any current or former employee of Operator to severance
pay, unemployment  compensation or any similar payment, (ii) accelerate the time
of payment or vesting,  or increase the amount of, any  compensation  due to any
such employee or former employee,  or (iii) directly or indirectly result in any

contracts  for fire,  casualty,  liability,  well  control  and  other  forms of

          Section 7.1 Operation of the Subject Assets Prior to Closing.

         (a) From and after the date of execution of this Agreement, and subject
to the provisions of applicable  operating and other agreements,  Operator shall
operate and  administer  the  Subject  Assets in a good and  workmanlike  manner
consistent with its past



                                      -34-








practices,  and  Operator  and  Working  Interest  Owners  shall  carry on their
businesses with respect to the Producing  Properties in  substantially  the same
manner as before  execution of this  Agreement.  Operator  and Working  Interest
Owners shall use their  reasonable  efforts to preserve in full force and effect
all oil and gas leases, operating agreements, easements, rights-of-way, permits,
licenses and  agreements  that relate to the Producing  Properties.  Without the
prior  written  consent of Buyer  (which  shall not be  unreasonably  withheld),
Operator and Working  Interest  Owner shall not modify,  terminate or settle any
dispute  arising  out  of  any  of the  agreements  relating  to  the  Producing
Properties and will not encumber,  sell, transfer,  assign,  convey,  farmout or
otherwise  dispose  of any of  the  Producing  Properties  other  than  personal
property  which is replaced by equivalent  property or consumed in the operation
of the Producing Properties.

         (b) Except for (i) emergency  action taken in the face of risk to life,
property or the  environment,  (ii) capital costs in connection  with  drilling,

Interest  Owner shall submit to Buyer for prior written  approval,  all requests

relating to the Producing Properties that involve individual commitments of more
than  $50,000.  If Buyer does not respond to any such request in writing  within
forty-eight (48) hours of the time the request is submitted, such matter will be
deemed approved.  Buyer  acknowledges  that Operator and Working Interest Owners
own undivided interests in the Subject Assets, and Buyer agrees that the acts or
omissions of the other working interests owners shall not constitute a violation
of the  provisions of this Article VII, nor shall any action  required by a vote
of working  interest owners  constitute such a violation so long as Operator and
Working  Interest  Owners have voted their  interests in a manner that  complies
with the  provisions of this Article VII. The  obligations  of Working  Interest
Owners and  Operator  under this  Article VII with respect to any portion of the
Subject  Assets not operated by either the Working  Interest  Owners or Operator
shall be  construed to require  that  Working  Interest  Owners and Operator use
reasonable  efforts  (without being  obligated to incur any expense or institute
any cause of action) to cause the  operator of the  Subject  Assets to take such
actions or render such  performance  within the  constraints  of the  applicable
operating agreements and other applicable agreements.

revised  Statement  setting forth the actual  Purchase  Price  Adjustments.  The
parties  shall  provide  each other such data and  information  as any party may

order to permit  such party to perform or cause to be  performed  an audit.  The
revised  Statement  shall  become final and binding upon the parties on the 60th
day  following  receipt  thereof by Buyer (the "Final  Settlement  Date") unless
Buyer gives written notice of its disagreement (a "Notice of  Disagreement")  to
Seller prior to such date.  Any Notice of  Disagreement  shall specify in detail

have not reached  agreement on such matters,  the matters that remain in dispute
shall  be  submitted  to  an  arbitrator  (the   "Arbitrator")  for  review  and
resolution.  The Arbitrator  shall be Arthur  Andersen & Co., or if such firm is
unable or unwilling to act, such other nationally recognized  independent public
accounting  firm as shall be agreed  upon by Buyer and  Seller in  writing.  The
Arbitrator  shall render a decision  resolving the matters in dispute  within 60
days following their submission to the



                                      -43-








Arbitrator.  The cost of any arbitration (including the fees and expenses of the
Arbitrator)  pursuant to this Section  10.6 shall be borne  equally by Buyer and

requested by Seller shall be borne by Seller,  and the fees and disbursements of

the Notice of  Disagreement  shall be borne by Buyer.  As used in this Agreement
the term "Final Statement" shall mean the revised Statement described in Section
10.6(a),  as prepared by Seller and as may be  subsequently  adjusted to reflect
any subsequent written agreement between the parties with respect thereto, or if
submitted to the Arbitrator, the revised Statement issued by the Arbitrator.

         (c) If the amount of the  Adjusted  Purchase  Price as set forth on the
Final Statement exceeds the amount of the estimated Adjusted Purchase Price paid
at  Closing,  then Buyer  shall pay to Seller  the amount by which the  Adjusted
Purchase  Price as set forth on the Final  Statement  exceeds  the amount of the
estimated  Adjusted  Purchase  Price paid at Closing  within five  business days
after the Final Settlement Date. If the amount of the Adjusted Purchase Price as
set  forth on the Final  Statement  is less  than the  amount  of the  estimated
Adjusted  Purchase  Price paid at Closing,  then  Seller  shall pay to Buyer the
amount by which the Adjusted  Purchase Price as set forth on the Final Statement
is less than the amount of the estimated Adjusted Purchase Price paid at Closing
within five business days after the Final Settlement Date.

         Section 10.7 Transfer Taxes.  All sales, use or other taxes (other than
taxes on gross income, net income or gross receipts) and duties, levies or other

transfers  undertaken pursuant to this Agreement shall be the responsibility of,
and shall be paid by, Buyer.

Interest and (ii) Seller  shall  retain all Records of Operator  that pertain to
the Excluded  Assets for a period of 6 years after  Closing and Buyer shall have
access thereto and the right to make copies thereof.

          (b) After the Closing Date, each party at the request of the other and
without additional  consideration,  shall execute and deliver, or shall cause to
be  executed  and  delivered  from  time to time  such  further  instruments  of
conveyance  and transfer and shall take such other action as the other party may

                             Purchased Shares of such Stockholder Indemnitor.

               (iii) In no event shall any amounts be  recovered  from a Selling
Stockholder (other than pursuant to Section 12.2(f)(ii))

                             (A) under this Agreement for any matter for which a
                             Claim Notice is not  delivered to the  indemnifying
                             party  prior to the close of  business  on the date
                             three years  following  the Closing  Date,  and the
                             indemnities granted by the Selling  Stockholders in
                             this Agreement shall terminate on such date;

                             (B) for any Losses until the Buyer Indemnitees have
                             suffered Losses resulting from matters described in
                             Section 12.2(d) for any Selling  Stockholder in the
                             aggregate  amount in excess of a deductible  of .6%
                             of the Adjusted Purchase Price  attributable to the
                             Purchased Shares of such Selling Stockholder, after
                             which  point  such  Selling   Stockholder  will  be
                             obligated  only to indemnify the Buyer  Indemnitees
                             from and against  further  Losses in excess of such
                             deductible; or

                             (C) for any Losses  after  Buyer  Indemnitees  have
                             suffered Losses resulting from matters described in
                             Section  12.2(d) in the aggregate  amount in excess
                             of 50% of the Adjusted Purchase Price  attributable
                             to   the   Purchased   Shares   of   such   Selling
                             Shareholder.




                                      -52-








provided,   however,  that  such  indemnities  shall  survive  (subject  to  any
applicable  deductible or cap) with respect only to the specific  matter that is
the subject of any Claim Notice  delivered in good faith in compliance  with the
requirements  of this Section 12.2(f) until the earlier to occur of (x) the date
on which a final nonappealable  resolution of the matter described in such Claim
Notice has been  reached or (y) the date on which the matter  described  in such
Claim  Notice  has  otherwise  reached  final  resolution.  Notwithstanding  the
foregoing, the Stockholder Indemnitors shall be jointly and severally liable for
the  indemnity  granted in Section  12.2(c)(vii)  with respect to Tax Losses and
Section 12.2(c)(vi) with regard to Black Stone Oil Company v. C.C. Lilley, Inc.

         (g) All claims for  indemnification  under this  Section  12.2 shall be
asserted and  resolved  pursuant to this Section  12.2(g).  Any person  claiming
indemnification  hereunder is hereinafter referred to as the "Indemnified Party"
and any person  against whom such claims are asserted  hereunder is  hereinafter
referred  to as the  "Indemnifying  Party."  In the event  that any  Losses  are
asserted against or sought to be collected from an Indemnified  Party by a third
party,  said Indemnified Party shall with reasonable  promptness  provide to the
Indemnifying  Party a Claim  Notice.  Notwithstanding  the  preceding  sentence,
failure of the Indemnified  Party to give notice hereunder shall not release the
Indemnifying  Party from its  obligations  under this Article XII, except to the
extent the  Indemnifying  Party is actually  prejudiced  by such failure to give
notice.  The Indemnifying Party shall have 30 days from the personal delivery or
receipt of the Claim  Notice (the  "Notice  Period")  to notify the  Indemnified
Party (i) whether or not it disputes the liability of the Indemnifying  Party to
the Indemnified  Party hereunder with respect to such Losses and/or (ii) whether
or not it desires,  at the sole cost and expense of the  Indemnifying  Party, to
defend the Indemnified Party against such Losses;  provided,  however,  that any
Indemnified  Party is hereby authorized prior to and during the Notice Period to
file any  motion,  answer or other  pleading  that it shall  deem  necessary  or
appropriate to protect its interests or those of the Indemnifying  Party (and of
which it shall have given notice and opportunity to comment to the  Indemnifying
Party) and not  prejudicial  to the  Indemnifying  Party.  In the event that the
Indemnifying  Party notifies the Indemnified Party within the Notice Period that
it desires to defend the Indemnified Party against such Losses, the Indemnifying
Party  shall  have the right to defend  all  appropriate  proceedings,  and with
counsel of its own  choosing,  which  proceedings  shall be promptly  settled or
prosecuted by them to a final  conclusion.  If the Indemnified  Party desires to
participate in, but not control,  any such defense or settlement it may do so at
its  sole  cost  and  expense.  If  requested  by the  Indemnifying  Party,  the
Indemnified  Party  agrees  to  cooperate  with the  Indemnifying  Party and its
counsel in contesting any Losses that the  Indemnifying  Party elects to contest
or,  if  appropriate  and  related  to the  claim in  question,  in  making  any
counterclaim  against  the  person  asserting  the third  party  Losses,  or any
cross-complaint  against  any  person.  No claim  may be  settled  or  otherwise
compromised without the prior written consent of the Indemnifying Party.




                                      -53-








         (h)  Notwithstanding  anything to the contrary  contained  herein,  the
amount of any Losses for which  indemnification  is provided  under this Section
12.2 shall be net of any amounts  actually  recovered by the  Indemnified  Party
under  insurance  policies  in  effect  at or prior  to the  Closing  Date.  The
Indemnified Party shall use its reasonable efforts to enforce any such insurance
policies and shall give such  notices  under such  policies as the  Indemnifying
Party reasonably may request by notice in writing. The Indemnified Party and the
Indemnifying  Party shall  cooperate in connection with any claim under any such
insurance policies covered by this Section 12.2(h).

         (i) THE TERM  "LOSSES"  SHALL  SPECIFICALLY  INCLUDE  STRICT  LIABILITY
IMPOSED ON AN INDEMNIFIED  PARTY WHETHER UNDER  ENVIRONMENTAL  LAWS OR OTHERWISE
AND IT IS THE INTENT OF THE PARTIES  THAT THE  INDEMNIFICATION  OBLIGATIONS  SET
FORTH  IN THIS  ARTICLE  XII  SHALL  INCLUDE  AN  OBLIGATION  ON THE PART OF THE
INDEMNIFYING  PARTY TO INDEMNIFY THE INDEMNIFIED  PARTY AGAINST STRICT LIABILITY
ARISING  IN  CONNECTION  WITH A MATTER  FOR  WHICH  SUCH  PARTY IS  ENTITLED  TO
INDEMNIFICATION UNDER THIS ARTICLE.

          Section 13.1 Disclaimers of Representations and Warranties.

         The express  representations and warranties of Seller contained in this
Agreement  are  exclusive  and  are in  lieu of all  other  representations  and
warranties,  express,  implied or statutory.  BUYER ACKNOWLEDGES THAT SELLER HAS
NOT MADE, AND SELLER HEREBY  EXPRESSLY  DISCLAIMS AND NEGATES,  AND BUYER HEREBY

OTHERWISE  PROVIDED  HEREIN,  THE ACCURACY,  COMPLETENESS  OR MATERIALITY OF ANY
INFORMATION,  DATA OR OTHER  MATERIALS  (WRITTEN  OR ORAL)  NOW,  HERETOFORE  OR
HEREAFTER   FURNISHED  TO  BUYER  BY  OR  ON  BEHALF  OF  SELLER,  AND  (c)  THE
ENVIRONMENTAL CONDITION OF THE SUBJECT ASSETS.  NOTWITHSTANDING  ANYTHING TO THE
CONTRARY IN THIS AGREEMENT,  SELLER EXPRESSLY  DISCLAIMS AND NEGATES,  AND BUYER
HEREBY WAIVES,  AS TO PERSONAL  PROPERTY,  EQUIPMENT,  INVENTORY,  MACHINERY AND
FIXTURES CONSTI-



                                      -54-








TUTING A PART OF THE  SUBJECT  ASSETS (i) ANY  IMPLIED OR  EXPRESS  WARRANTY  OF
MERCHANTABILITY,  (ii)  ANY  IMPLIED  OR  EXPRESS  WARRANTY  OF  FITNESS  FOR  A
PARTICULAR  PURPOSE,  (iii) ANY  IMPLIED OR EXPRESS  WARRANTY OF  CONFORMITY  TO
MODELS OR SAMPLES OF MATERIALS,  (iv) ANY RIGHTS OF PURCHASERS UNDER APPROPRIATE
STATUTES TO CLAIM  DIMINUTION OF  CONSIDERATION OR RETURN OF THE PURCHASE PRICE,
(v) ANY IMPLIED OR EXPRESS  WARRANTY OF FREEDOM  FROM VICES OR DEFECTS,  WHETHER
KNOWN OR UNKNOWN,  (vi) ANY AND ALL IMPLIED WARRANTIES EXISTING UNDER APPLICABLE
LAW, AND (vii) ANY IMPLIED OR EXPRESS WARRANTY REGARDING ENVIRONMENTAL LAWS, THE
RELEASE OF MATERIALS INTO THE  ENVIRONMENT  OR PROTECTION OF THE  ENVIRONMENT OR
HEALTH,  IT BEING THE EXPRESS  INTENTION OF BUYER AND SELLER THAT (EXCEPT TO THE
EXTENT EXPRESSLY PROVIDED IN HEREIN) THE REAL AND PERSONAL PROPERTY,  EQUIPMENT,
INVENTORY,  MACHINERY,  AND  FIXTURES  CONSTITUTING  PART OF THE ASSETS SHALL BE
CONVEYED TO BUYER AS IS AND IN THEIR  PRESENT  CONDITION AND STATE OF REPAIR AND
BUYER  REPRESENTS  TO  SELLER  THAT  BUYER  HAS MADE OR  CAUSED  TO BE MADE SUCH
INSPECTIONS  WITH  RESPECT  TO  THE  REAL  AND  PERSONAL  PROPERTY,   EQUIPMENT,
MACHINERY,  INVENTORY  AND  FIXTURES AS BUYER DEEMS  APPROPRIATE  AND BUYER WILL
ACCEPT SAME AS IS, WHERE IS, WITH ALL FAULTS,  IN THEIR  PRESENT  CONDITION  AND
STATE OF  REPAIR.  Seller  and Buyer  agree  that,  to the  extent  required  by
applicable law to be effective,  the disclaimers of certain warranties contained
in this section are "conspicuous" disclaimers for the purposes of any applicable
law, rule or order.

          Section 13.2 Waiver of Texas DTPA.

         (a) It is the intent of the Parties  that  Buyer's  rights and remedies
with respect to this Agreement and the transactions contemplated hereby and with
respect  to all acts or  practices  of  Seller,  past,  present  or  future,  in
connection with this Agreement and the transactions contemplated hereby shall be
governed by legal  principles  other than the Texas  Deceptive  Trade  Practices
Consumer  Protection  Act, Tex. Bus. & Com. Code Ann. ss. 17.41 et seq.  (Vernon
1987  and  Supp.   1994)  (the  "DTPA").   As  such,  Buyer  hereby  waives  the
applicability  of the DTPA to this Agreement and the  transactions  contemplated
hereby and any and all duties,  rights or remedies  that might be imposed by the
DTPA,  whether such duties,  rights or remedies are applied directly by the DTPA
itself or indirectly in connection with other statutes; provided, however, Buyer
does not waive Section 17.555 of the DTPA.  Buyer  acknowledges,  represents and
warrants that it is purchasing the Purchased Subject Assets and Purchased Shares
for  commercial or business  use; that Buyer has assets of Five Million  Dollars
($5,000,000) or more according to its most recent financial  statement  prepared
in accordance  with generally  accepted  accounting  principles;  that Buyer has
knowledge and  experience  in financial  and business  matters that enable it to
evaluate the



                                      -55-








merits  and  risks  of a  transaction  such  as  this;  and  that it is not in a
significantly disparate bargaining position with Seller.

         (b) Buyer  expressly  recognizes  that the price for which  Seller  has
agreed to perform its obligations  under this Agreement has been predicated upon
the  inapplicability  of the DTPA and this  waiver  of the DTPA.  Buyer  further
recognizes that Seller, in determining to proceed with the entering into of this
Agreement,  has expressly relied on this waiver and the  inapplicability  of the
DTPA.

          Section 13.3 Casualty Loss.

          (a) Buyer  shall  assume  all risk of loss with  respect  to,  and any
change in the  condition of, the Subject  Assets from the  Effective  Time until
Closing for production of oil, gas and/or other  hydrocarbons  through depletion
(including the watering-out of any well,  collapsed casing or sand  infiltration
of any well) or otherwise.

          (b) If after the  Effective  Time and prior to the Closing any part of
the Subject Assets shall be damaged or destroyed by fire or other casualty or if
any part of the Subject Assets shall be taken in condemnation or under the right
of  eminent  domain or if  proceedings  for such  purposes  shall be  pending or
threatened  ("Casualty  Loss"),  Buyer may elect to (i) cause the Subject Assets
affected by the  Casualty  Loss to be treated as Excluded  Assets and reduce the
Purchase Price by the Allocated  Value of the Subject Asset  affected,  in which
case Seller shall retain all insurance proceeds,  condemnation proceeds, claims,
awards and other  payments  arising out of such  Casualty  Loss, or (ii) require
Working  Interest  Owner to (y) transfer to Buyer the  Purchased  Subject  Asset
affected  notwithstanding  such  Casualty Loss and (z) transfer to Buyer Working
Interest  Owner's share of any  insurance  proceeds and  condemnation  proceeds,
claims,  awards and other payments arising out of such Casualty Loss and require
Operator to retain and not  distribute  to the Selling  Stockholders  Operator's
share of any such insurance proceeds,  condemnation proceeds,  claims, awards or
payments.  Working Interest Owner and Operator shall not voluntarily compromise,
settle or adjust any amounts  payable by reason of a Casualty Loss without first
obtaining the consent of Buyer.  Notwithstanding the foregoing, if following any
Casualty  Loss,  Working  Interest  Owner or Operator  repairs or  replaces  the
damaged or destroyed  property to substantially  its original  condition,  Buyer
shall be required to purchase the Subject Assets affected  without any reduction
in the Purchase  Price and Seller shall retain all insurance  proceeds and other
amounts arising out of such Casualty Loss.

          Section 13.4 Exclusive  Remedies.  THE PARTIES  ACKNOWLEDGE  AND AGREE
THAT THE  REMEDIES  SET  FORTH IN THIS  AGREEMENT,  INCLUDING  THE  DEDUCTIBLES,
LIABILITY LIMITS, SURVIVAL PERIODS, DISCLAIMERS AND LIMITATIONS ON REMEDIES, ARE
INTENDED TO BE, AND SHALL BE, THE EXCLUSIVE  REMEDIES WITH RESPECT TO ANY ASPECT
OF THE TRANSACTIONS



                                      -56-








CONTEMPLATED  BY  THIS  AGREEMENT.   EACH  PARTY  HEREBY  RELEASES,  WAIVES  AND
DISCHARGES,  AND  COVENANTS  NOT TO SUE WITH  RESPECT TO, ANY CAUSE OF ACTION OR
CLAIM  NOT  EXPRESSLY  PROVIDED  FOR  IN  THIS  AGREEMENT   INCLUDING,   WITHOUT
LIMITATION,  CLAIMS UNDER STATE OR FEDERAL SECURITIES LAWS,  AVAILABLE AT COMMON
LAW OR BY STATUTE (INCLUDING FRAUD CLAIMS UNDER CHAPTER 27 OF THE TEXAS BUSINESS
AND COMMERCE CODE).

          Section 13.5 Texas Revised  Partnership  Act. Buyer agrees that if any
Seller which is a Texas general partnership adopts the Texas Revised Partnership
Act ("TRPA")  prior to the Closing Date,  TRPA shall have the same effect on any
claim of Buyer arising under this  Agreement  against such  partnership  and the
partners  thereof as if TRPA had been adopted by such  partnership  prior to the
date of execution of this Agreement.

                                   ARTICLE XIV

                                  Miscellaneous

         Section 14.1 HSR Act. Within 10 days after the execution  hereof,  each
party will file or cause its ultimate  parent entity  (within the meaning of the
HSR Act) to file all materials  required to be filed by it under the HSR Act and
will promptly file any  supplemental  materials  required and will comply in all
material  respects  with the  requirements  of the HSR Act.  Each of the parties
shall request early termination of the HSR Act waiting period and any filings to
be made. None of the parties shall take any action that is reasonably  likely to
have the effect of  delaying,  impairing or impeding the receipt of any required
approvals  and will use their  commercially  reasonable  efforts to secure  such
approvals as promptly as possible.

         Section 14.2 Expenses.  Each party shall be solely  responsible for all
expenses,  including due diligence  expenses,  incurred by it in connection with
this  transaction,  and no party shall be entitled to any reimbursement for such
expenses from the other party hereto.



                                      -57-









         Section  14.3   Independent   Investigation.   Buyer   represents   and
acknowledges that (i) it is knowledgeable of the oil and gas business and of the
usual and  customary  practices  of  producers  such as Seller,  (ii) it has had
access to the Subject Assets, the officers and employees of Seller and Operator,
and the  books,  records  and  files of  Seller  and  Operator  relating  to the
Purchased Subject Assets and Operator, and (iii) in making the decision to enter
into this Agreement, Buyer has relied solely on the basis of its own independent
due diligence  investigation  and upon the  representations  and warranties made
herein. Accordingly,  Buyer acknowledges that Sellers have not made, and Sellers
hereby expressly disclaim and negate, any representation or warranty (other than
those  express  representations  and  warranties  contained  herein),   express,
implied,  at common law,  by statute or  otherwise,  relating  to the  Purchased
Subject Assets or the Purchased Shares.

         Section 14.4 Document Retention. As used in this Section 14.4, the term
"Documents" shall mean all files,  documents,  books,  records and other data of
Operator (other than those that Seller has retained a copy of),  including,  but
not limited to: financial and tax accounting  records;  land, title and division
of interest files; contracts;  engineering and well files; and books and records
related to the business of Operator or the operation of the Subject Assets prior
to the Closing  Date.  Buyer agrees  that,  to the extent the  Documents  are in
Buyer's or Operator's possession,  the Documents shall be open for inspection by
representatives  of Seller at reasonable times and upon reasonable notice during
regular  business  hours for a period of 6 years  following the Closing Date (or
for such longer  period as may be required by law or  governmental  regulation),
and that Seller may during such period at its expense  make such copies  thereof
as it may reasonably request.

         Section 14.5 Entire  Agreement.  This  Agreement,  the  documents to be
executed  hereunder,  and the exhibits  attached  hereto  constitute  the entire
agreement between the Parties hereto pertaining to the subject matter hereof and
supersede all prior  agreements,  understandings,  negotiations and discussions,
whether oral or written, of the Parties pertaining to the subject matter hereof.
No supplement,  amendment, alteration,  modification or waiver of this Agreement
shall be binding unless  executed in writing by the Parties hereto and expressly
referencing this Agreement.

         Section  14.6  Waiver.  No  waiver  of any of the  provisions  of  this
Agreement shall be deemed or shall  constitute a waiver of any other  provisions
hereof (whether or not similar),  nor shall such waiver  constitute a continuing
waiver unless otherwise expressly provided.

         Section 14.7 No Solicitation. Sellers shall, prior to the Closing Date,
neither  solicit bids for the Subject  Assets or Purchased  Shares nor negotiate
the sale of the  Subject  Assets or  Purchased  Shares with any party other than
Buyer or Guarantor.




                                      -58-








          Section  14.8  Publicity.  Sellers and Buyer shall  consult  with each
other with regard to all publicity and other releases  concerning this Agreement
and the transactions  contemplated  hereby and, except as required by applicable
law or the applicable  rules or regulations  of any  governmental  body or stock
exchange,  no party shall issue any such publicity or other release  without the
prior written consent of the other party hereto.

          Section  14.9  Captions.  The  captions  in  this  Agreement  are  for
convenience  only  and  shall  not  be  considered  a  part  of  or  affect  the
construction or interpretation of any provision of this Agreement.

          Section 14.10 No Third Party Beneficiaries.  Nothing in this Agreement
shall  provide  any benefit to any third party or entitle any third party to any
claim, cause of action,  remedy or right of any kind, it being the intent of the
Parties that this Agreement shall not be construed as a third party  beneficiary
contract.

         Section 14.11 Assignment. Except as provided in the following sentence,
no party may assign or delegate any of its rights or duties  hereunder,  without
the prior written consent of the other parties, and any assignment or delegation
made without such  consent  shall be void.  Buyer shall have the right to assign
its rights  hereunder  to an  affiliate  and may effect the  acquisition  of the
Purchased  Shares pursuant to a merger of Operator with and into an affiliate of
Buyer,  provided  in  each  instance  that  Guarantor  guarantees  all  of  such
assignee's  obligations  hereunder  pursuant  to a form  of  guaranty  agreement
substantially  the  same  as that  attached  as  Exhibit  G to be  executed  and
delivered by Guarantor to Seller prior to such  assignment or merger.  Except as
otherwise provided herein, this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective permitted successors, assigns
and legal representatives.

          Section 14.12 Governing Law. This Agreement, other documents delivered
pursuant  hereto and the legal  relations  between the Parties shall be governed
and construed in accordance with the laws of the State of Texas,  without giving
effect to  principles of conflicts of laws that would result in the selection of
an alternate jurisdiction.

          Section 14.13 Notices. Any notice, communication, request, instruction
or other document required or permitted  hereunder shall be given in writing and

         Section  14.14  Severability.  If any term or other  provision  of this
Agreement is invalid,  illegal or incapable of being enforced by any rule of law
or public policy,  all other  conditions and provisions of this Agreement  shall

negotiate  in good faith to modify this  Agreement  so as to effect the original

same counterpart.  If counterparts of this Agreement are executed, the signature
pages from various  counterparts  may be combined into one composite  instrument
for all purposes. All counterparts together shall constitute only one Agreement,
but each counterpart shall be considered an original.

make and  receive  payments  hereunder  on  behalf of such  Seller,  to give and
receive notices on behalf of such Seller  hereunder (and promptly send copies of
any notices to each affected

on any  extensions  to the  Closing  Date on behalf of such Seller and to select
title and environmental  consultants on behalf of such Seller.  BSHP's authority
does not  include the  ability to modify or amend this  Agreement  in any manner
without each Seller's  consent.  Buyer may rely upon any instrument  executed or
other action taken by BSHP on behalf of Seller pursuant to this Section 14.16 to
the same extent as if such instrument had been executed or action had been taken
by each Seller.

          Section 14.17 W.T. Carter & Bro. Buyer acknowledges that W.T. Carter &
Bro.  is the lessor  with  respect to certain of the  Properties.  Buyer  hereby
acknowledges and agrees that the terms of the relevant leases permit W.T. Carter
& Bro.  to take in kind  and  separately  dispose  of its  royalty  share of the
production  therefrom  or  attributable  thereto free and clear of any costs and
expenses of gathering, handling, treating or transporting such production to the
final point of sale by lessee and/or  lessee's  assigns,  and that W.T. Carter &
Bro. will have the right, but not the obligation, to market its royalty share of
production on the same terms as Buyer's  production from such leases is marketed
free and clear of said costs and expenses of gathering,  handling,  treating and
transportation.

          Section 14.18 Champion C-2.

          (a) Operator has commenced the drilling of the Champion  International
C No. 2 well.  Promptly  after such well  reaches its total depth (as defined in
the existing drilling contract for such well), the current operator of such well
(Operator,  BSHP or its designee, as applicable) shall run or cause to be run in
such well an induction  log and porosity  log as a reasonably  prudent  operator
(provided  that  conditions  permit  such logs to be run) and  promptly  deliver
copies of such logs to Buyer.  Buyer shall have forty-eight  hours after receipt
of such logs (the "C-2 Notice  Period") to notify  Sellers  whether it elects to
reject the Champion C-2 Assets.

          (b) If Buyer elects to reject the Champion C-2 Assets, and such notice
of rejection is received by Sellers prior to Closing,  the Purchase  Price shall
not be adjusted  upward by the costs and  expenses  thereof.  If Buyer elects to
reject the  Champion  C-2 Assets,  and such notice of  rejection  is received by
Sellers  after  Closing,  Sellers  shall pay Buyer an amount equal to the actual
costs and expenses  incurred by Sellers after the  Effective  Time to drill such
well to total depth.

          (c) BSHP or its designee shall have the sole right to operate the well
after Closing until the end of the C-2 Notice Period.  If Buyer elects to reject
the  Champion  C-2  Assets,  BSHP or its  designee  shall have the sole right to
continue to operate said well.




                                      -61-








         (d) In the event that  Sellers  receive  notice,  within the C-2 Notice
Period,  of Buyer's  election to reject the  Champion  C-2  Assets,  and Sellers
complete the Champion International C No. 2 well as a producer, then (i) if such
completion occurs prior to Closing,  the Champion C-2 Assets shall be treated as
Excluded Assets,  and (ii) if such completion occurs after Closing,  Buyer shall
convey to Sellers, the Champion C-2 Assets promptly after such completion.

          Section  14.19  Guaranty  Agreement.  Pursuant  to  the  terms  of the
