                  Closing,  (ii) incurred and paid by Seller,  including without

                                       2


                           (3) taxes  paid by Seller  for  assessments  based on
                  ownership  of the  Interests  after the  Effective  Time,  the
                  production  of  hydrocarbons  therefrom,  or  the  receipt  of
                  proceeds  attributable  thereto (excluding income taxes) after
                  the Effective Time.

                           (4)  an  amount   equal  to  all   prepaid   expenses
                  attributable to the Interests paid by Seller and  attributable
                  to the period  from and after the  Effective  Time,  including
                  without  limitation  prepaid insurance and prepaid ad valorem,
                  property,  production  and other taxes accruing to the benefit
                  of Buyer subsequent to the Effective Time.

                  (b) The Purchase Price shall be decreased by the following:

                           (1) the Deposit;

                           (2)  the  amount  of  net  proceeds  or  other  value
                  received by Seller for the sale or  disposition of Substances,
                  as defined  herein,  including  net proceeds  from the sale of
                  liquids and other constituents  removed in gas plants or other
                  processing  facilities  for  production  occurring  after  the
                  Effective Time;

                           (3) the amount of proceeds or other value received by
                  Seller for the sale or disposition after the Effective Time of
                  any portion of the Interests;

                           (4) an amount equal to the value of all uncured Title
                  Defects as determined under Section 5.08; and

                           (5) the  amount of all unpaid  taxes and  assessments
                  based  on  the  ownership  of  property,   the  production  of
                  hydrocarbons  or the  receipt of  proceeds,  excluding  income
                  taxes,  accruing to the Interests  prior to the Effective Time
                  and  for  the  payment  of  which  Buyer   assumes   liability
                  subsequent to Closing.  If possible,  this adjustment shall be
                  computed  using the tax rate and  values for the tax period in
                  question.  If this is not possible,  the  adjustment  shall be
                  based on the taxes assessed for the immediately  preceding tax
                  period.  If taxes  assessed for the  preceding  tax period are
                  determined  to be more or less  than  the  actual  taxes,  the
                  difference  shall be a  Post-Closing  Adjustment or Subsequent
                  Adjustment under Sections 9.01 and 9.02.

         2.04 Payment of Adjusted  Purchase Price.  At Closing,  Buyer shall pay
Seller an amount equal to the Adjusted  Purchase Price in immediately  available
funds.

         2.05 Allocation of Purchase  Price/Tangibles-Intangibles.  The Purchase
Price  shall  be  allocated  among  tangibles  and  intangibles  comprising  the
Interests as follows:  Ninety (90%) of the Purchase Price shall be attributed to
the Leases and associated  Contracts and Ten Percent (10%) of the Purchase Price
shall be attributed to Equipment and other personal  property.  Buyer and Seller
agree to be bound by the  allocation of the Purchase  Price among  tangibles and
intangibles  set forth  herein for all  purposes;  to  consistently  report such
allocations for all federal,  state and local income tax purposes; and to timely
file all reports  required by the  Internal  Revenue  Code of 1986,  as amended,
concerning the Purchase Price allocation.

                         REPRESENTATIONS AND DISCLAIMERS

         3.01 Seller's Representations. Seller represents to Buyer that:

                  (a) Seller is a  corporation  organized,  existing and in good
         standing under the laws of the State of Delaware and is qualified to do
         business  in, and is in good  standing  under the laws of the States of
         Louisiana  and Texas.  Seller is  qualified  under  applicable  law and
         regulation to own the Interests.  With respect to all persons  claiming
         by through or under  Seller but not  otherwise,  Seller  has,  and will
         convey to Buyer, Defensible Title (as defined in Section 5.06 below) to
         the  Interests.  Seller  warrants  and  agrees to  defend  title to the
         Interests against the lawful claims of all persons claiming by, through
         or under Seller, but not otherwise.

                  (b)  Seller  has the  authority  to carry on its  business  as
         presently  conducted,  to enter into this  Agreement and to perform its
         obligations under this Agreement.

                  (c) The  execution  and delivery of this  Agreement  have been
         authorized by all necessary  action,  corporate and  otherwise,  on the
         part of Seller.  Execution and delivery of this Agreement does not, and
         the  consummation  of the  transactions  contemplated by this Agreement
         will not,  violate or be in conflict  with any  agreement,  instrument,
         judgment, order, decree, law or regulation by which Seller is bound.

                  (d) Subject to laws and  equitable  principles  affecting  the
         rights of creditors,  this Agreement is a binding  obligation of Seller
         enforceable according to its terms.

                  (e) Except as set forth on Schedule  3.01(e),  no suit, claim,
         demand or  investigation,  of which  Seller  has  received  notice,  is
         pending or, to the best of Seller's  knowledge,  threatened  that might
         result in impairment  or loss or  diminution  of Seller's  title to the
         Interests or otherwise  adversely  affect the Interests in any material
         respect. There are no bankruptcy or reorganization  proceedings pending
         or  threatened  against  Seller.  As  used in this  Section  3.01,  the
         expression "best of Seller's knowledge" means actual knowledge acquired
         by the  management  of Seller in the ordinary  course and  operation of
         Seller's business without special or particular investigation or review
         of  Seller's  business  affairs  in  connection  with  the  transaction
         contemplated herein or otherwise.

                  (f)  Contracts  which burden or will burden or encumber or are
         otherwise material to the ownership,  use or operation of the Interests
         are  described  on Exhibit A hereof,  were entered into in the ordinary
         course of business  and, if executed by Seller,  were duly executed and
         delivered by Seller and are in force according to their terms.  Neither
         Seller, nor any other party to Seller's knowledge,  is in breach of any
         obligation  which might adversely  affect the Interests in any material
         respect.

                  (i) This section is intentionally omitted.

                  (j) To the  best  of  Seller's  knowledge  taxes  based  on or
         measured by the  ownership of property,  the  production  or removal of
         hydrocarbons  and the receipt of proceeds which are due and relating to
         the Interests have been properly paid,  subject to possible  adjustment
         for volume or price corrections.

                  (k) Seller is timely  receiving its share of proceeds from the
         sale  of  hydrocarbons  produced  from  the  Leases  without  suspense,
         counterclaim or set-off. To the best of Seller's  knowledge,  there has
         been no  production  of  hydrocarbons  from the Leases in excess of the
         allowable  production  established  pursuant  to  applicable  state  or
         federal  law or  regulation  that  would  result  in a  restriction  on
         production from the Leases subsequent to the Effective Time.

                  (l) This section is intentionally omitted.

                  (m) Seller has incurred no liability  for brokers' or finders'
         fees related to the  transactions  contemplated  by this  Agreement for
         which Buyer shall be liable.

                  (n)  To  the  best  of  Seller's   knowledge,   there  are  no
         outstanding  authorities  for  expenditures  or  any  oral  or  written
         commitments or proposals to conduct  operations on the Leases which are
         required  to be  approved  by  non-operators  under  the  terms  of the
         applicable joint operating agreement.

                  (o)  Except  as  set  forth  on  Schedule  3.01(o),  as of the
         Effective  Time,  no portion of the Interests is over  produced,  under
         produced or otherwise  subject to an imbalance in respect of substances
         produced from the Leases.

         3.02 Buyer's Representations. Buyer represents to Seller as follows:

                  (a) Buyer is a  corporation  organized,  existing  and in good
         standing under the laws of the State of Delaware and is qualified to do
         business and is in good standing  under the laws of the States of Texas
         and Louisiana.  Buyer is qualified under  applicable law and regulation
         to own the  Interests  and, in  particular,  Buyer is  qualified  to do
         business in each of the States and on the  Continental  Shelf,  Gulf of
         Mexico,  in which the  Interests  are located to the extent the laws of
         such place require Buyer to so qualify.

                  (b)  Buyer  has the  authority  to  carry on its  business  as
         presently  conducted,  to enter into this  Agreement and to perform its
         obligations under this Agreement.


                                       5


                  (c) The  execution  and  delivery of this  Agreement  has been
         authorized by all necessary  action,  corporate and  otherwise,  on the
         part of Buyer.  Execution and delivery of this  Agreement does not, and
         the  consummation  of the  transactions  contemplated by this Agreement
         will not,  violate or be in conflict  with any  agreement,  instrument,
         judgment, order, decree, law or regulation by which Buyer is bound.

                  (d) Subject to laws and  equitable  principles  affecting  the
         rights of creditors,  this  Agreement is a binding  obligation of Buyer
         enforceable  according  to  its  terms.  There  are no  bankruptcy  nor
         reorganization proceedings pending or, to Buyer's knowledge, threatened
         against Buyer.

                  (e) Buyer has incurred no  liability  for brokers' or finders'
         fees related to the  transactions  contemplated  by this  Agreement for
         which Seller shall be liable.

                  (f) There are no pending suits,  actions or other  proceedings
         in which  Buyer is a party (or, to Buyer's  knowledge,  which have been
         threatened to be instituted  against  Buyer) which affect the execution
         and delivery of this Agreement or the  consummation of the transactions
         contemplated hereby.

                  (g) Buyer is a knowledgeable purchaser,  owner and operator of
         oil and gas  properties,  has the ability to evaluate the Interests for
         purchase,  and is acquiring  the  Interests for its own account and not
         with the intent to make a  distribution  in violation of the Securities
         Act of 1933 as amended.

                                    COVENANTS

         4.01  Seller's  Covenants.  Seller  covenants  and agrees with Buyer as
follows:


                  (a) Following  execution of this  Agreement and until Closing,

         be paid all rentals and other payments necessary to maintain the Leases
         in force  according  to their  terms and comply  with all  express  and
         implied covenants  contained in the Leases or Contracts;  (vi) exercise
         due  diligence  in  safeguarding  the  Interests  and  maintaining  the
         confidentiality  of all  data and  other  confidential  or  proprietary
         materials relating to the Interests; (vii) promptly notify Buyer of all
         significant   operations   which  are  proposed  with  respect  to  the
         Interests;  and  (viii)  use  efforts,  consistent  with the  standards
         expected of a reasonably prudent operator but without any obligation to


                                       6


         pay  money  to  obtain  any  consents,  waivers  (including  waiver  of
         preferential  purchase rights) and approvals  required of third parties
         or  governmental  authorities in connection  with  consummation  of the
         transactions  contemplated by this Agreement.  Buyer  acknowledges that
         Seller  owns  undivided  interests  in the  Leases  and  that  acts  or
         omissions of other  owners of  undivided  interests in the Leases shall
         not be a breach of any covenant in this Agreement.  Seller shall not be
         obligated  to perform  any act which  would be in breach of a provision
         in, or its duties under, a Lease,  Contract or applicable  law, rule or
         regulation.

                  (b) Following  execution of this Agreement,  Seller shall not,
         without  Buyer's  consent;  (i) abandon any well capable of  commercial
         production; (ii) release all or a portion of a Lease; (iii) commence or
         consent to an  operation  estimated  to cost an amount in excess of the
         amount an operator is entitled to expend without non-operator  approval
         under  the  applicable  operating  agreement(s)   (excluding  emergency
         operations and  operations  undertaken to avoid a penalty or forfeiture
         provision of any  applicable  agreement or order);  (iv) create a lien,
         security  Interest or other  encumbrance on the Interests;  (v) sell or
         dispose of the Interests (except in connection with preferential rights
         to purchase)  other than  Interests  sold,  consumed or produced in the
         ordinary course of business;  (vi) amend a Lease or amend a Contract or
         Account or enter into new contracts  affecting the Interests other than
         in the ordinary course of business;  (vii) waive,  compromise or settle
         any claim that diminishes or adversely burdens an Interests.

                  (c)  Following  the  execution  of this  Agreement  and  until
         Closing,  Seller  will  provide  Buyer  and its  attorneys,  employees,
         accountants,    engineers,   consultants   and   agents   (collectively
         "representatives"),  at Buyer's sole expense, risk and cost, reasonable
         access,  during  business  hours, to the Contracts and other records of
         Seller  pertaining  to the ownership  and/or  operation of the Interest
         (including,  without limitation, title files, division order files, and
         production,  severance  and ad valorem tax  records) for the purpose of
         Buyer's  conducting a due diligence review of the Interests  insofar as
         the same are in Seller's  possession  or control,  or insofar as Seller
         has access to the same,  and to the extent,  in each case,  that Seller
         may do so without  violating legal constraints or any legal obligation.
         Seller shall not be obligated to furnish any updated  abstracts,  title
         opinions or additional title  information  which are not in Seller's or
         its attorney's  possession,  but shall  cooperate with Buyer in Buyer's
         efforts  to  obtain  (at  Buyer's   expense)  such   additional   title
         information as Buyer may reasonably require.

         BUYER  RECOGNIZES AND AGREES THAT ALL MATERIALS MADE AVAILABLE TO BUYER
         AND ITS REPRESENTATIVES IN CONNECTION WITH THE TRANSACTION CONTEMPLATED
         HEREBY,  WHETHER MADE AVAILABLE  PURSUANT TO THIS SECTION OR OTHERWISE,
         ARE  MADE  AVAILABLE  TO  BUYER  AS  AN   ACCOMMODATION,   AND  WITHOUT
         REPRESENTATION  OR  WARRANTY  OF  ANY  KIND  AS  TO  THE  ACCURACY  AND
         COMPLETENESS  OF SUCH  MATERIALS.  NO  WARRANTY  OF ANY KIND IS MADE BY
         SELLER AS TO THE  INFORMATION  SUPPLIED TO BUYER OR WITH RESPECT TO THE
         INTERESTS TO WHICH THE INFORMATION  RELATES, AND BUYER EXPRESSLY AGREES
         THAT ANY  CONCLUSIONS  DRAWN  THEREFROM  SHALL BE THE RESULT OF ITS OWN
         INDEPENDENT REVIEW AND JUDGMENT.


                                       7



                  (d) Seller will identify,  with respect to all Interests,  (A)
         all preferential rights to purchase ("Preferential Rights") which would
         be applicable to the transaction  contemplated hereby and (B) the names
         and addresses of parties  holding such rights (it being agreed that, in
         attempting  to identify  such  Preferential  Rights,  and the names and
         addresses  of such  parties  holding  the  same,  Seller  shall  not be
         obligated to go beyond its own  records),  and (ii)  request,  from the
         parties so identified  (and in accordance  with the documents  creating
         such  rights),   execution  of  waivers  of   Preferential   Rights  so
         identified.  Seller shall have no  obligation  other than to attempt to
         identify  such  Preferential  Rights and to so request  such waivers of
         Preferential Rights (including,  without limitation,  Seller shall have
         no  obligation to assure that such waivers of  Preferential  Rights are
         obtained).  Except to the extent that Buyer can  establish  that Seller
         failed to fulfill  the  obligations  set forth  above in this  Section,
         Buyer shall  indemnify  and hold Seller (and its  officers,  directors,
         employees, attorneys, contractors and agents) harmless from and against
         all claims, actions, causes of action,  liabilities,  damages,  losses,
         costs or  expenses  (including,  without  limitation,  court  costs and
         attorney's  fees)  whatsoever  that arise out of the  failure to obtain
         consent or waivers of  Preferential  Rights with  respect to any of the
         Interests.  If a party  from whom a waiver of a  Preferential  Right is
         requested refuses to give such waiver, Seller will tender to such party
         the  required  Interest  (at a price equal to the amount  specified  in
         Exhibit  A  hereto  for  such  Interest,   reduced  appropriately,   as
         determined  by mutual  agreement of Buyer and the Seller,  if less than
         the entire  Interest  must be  tendered),  and to the extent  that such
         Preferential  Right is  exercised by such party,  and such  Interest is
         actually  sold to such party so  exercising  such right,  such Interest
         will be  excluded  from the  transaction  contemplated  hereby  and the
         Purchase Price will be adjusted downward by the amount actually paid to
         Seller by the party exercising such right.

         If the  holder of  Preferential  Rights  fails to fully  exercise  such
         rights and purchase the  Interests,  or part  thereof,  pursuant to the
         terms of this Agreement within 30 days of the Closing Date provided for
         herein  then  Buyer  will   purchase   such   Interests  as  originally
         contemplated  herein  before  the  holder of such  Preferential  Rights
         failed to consummate the purchase transaction.

         4.02  Buyer's  Covenants.  Buyer  covenants  and agrees  with Seller as
follows:


                  (a) Buyer and  Seller,  and their  respective  representatives
         shall keep confidential all terms and provisions of this Agreement, the
         transaction  contemplated  by this  Agreement,  and all information and
         data concerning the Interests, Seller's and Buyer's business, financial
         condition, operations, strategies and prospects.

                  (b) Buyer shall take or cause to be taken all such  actions as
         may be  necessary or advisable to  consummate  and make  effective  the
         purchase of the Interests  and the  transactions  contemplated  by this
         Agreement  and to  assure  that as of the  Closing  Date it will not be
         under any material  corporate,  legal or contractual  restriction  that
         would prohibit or delay the timely consummation of such transactions.


                                       8


                  (c) Buyer shall cause all the  representations  and warranties
         of Buyer  contained in this  Agreement to be true and correct on and as
         of the Closing  Date.  To the extent the  conditions  precedent  to the
         obligations  of Seller  are within the  control of Buyer,  Buyer  shall
         cause such  conditions  to be satisfied on or prior to the Closing Date
         and,  to the extent the  conditions  precedent  to the  obligations  of
         Seller are not within the  control of Buyer,  Buyer shall take or cause
         to be  taken  all  such  commercially  reasonable  actions  as  may  be
         necessary to cause such  conditions  to be satisfied on or prior to the
         Closing Date.

                  (d)  Buyer   shall   promptly   notify   Seller   (i)  if  any
         representation  or warranty of Buyer  contained  in this  Agreement  is
         discovered to be or becomes  untrue,  or (ii) if Buyer fails to perform
         or comply with any covenant or agreement contained in this Agreement or
         it is  reasonably  anticipated  that Buyer will be unable to perform or
         comply with any covenant or agreement contained in this Agreement.

                                    ARTICLE 5
                                    ---------

                            Buyer's REVIEW AND TITLE

         5.01 Due Diligence. Buyer may, prior to Closing and at its cost, review
data  and   information,   title   examination   and  other   examinations   and
investigations in respect of the Interests.  Should, as a result of examinations
and investigations,  or otherwise, one or more matters come to Buyer's attention
which would  constitute a Title Defect,  as described below, and should there be
one or more of such Title  Defects  which Buyer is  unwilling to waive and close
the transaction  contemplated  herein  notwithstanding  the fact that such Title
Defects  exist,  Buyer shall notify  Seller in writing of such Title  Defects as
soon as the same are  identified  by Buyer,  but in no event  later than 10 days
prior to the Closing  Date.  Such  notification  shall include for each asserted
Title Defect (i) a description  of the Title Defect and the Interest to which it
applies;  (ii) an  explanation  of the basis for the claim of a Title Defect and
(iii) the amount by which Buyer would  propose to adjust the  Purchase  Price in
view of such Title  Defect.  Buyer's  failure to give  notice of a Title  Defect
within the time and in the manner required by this Section 5.01 shall constitute
a waiver by Buyer of the Title  Defect and the Title Defect will be treated as a
Permitted Encumbrance as set forth below.

         5.02 Access to Interests. Following the execution of this Agreement and
until  Closing,  subject to the consent and  cooperation  of operators and other
third parties,  Seller shall provide Buyer and its representatives access to the
Interests  and the right to observe  operations  and  inspect any and all of the
Interests,  Equipment,  improvements and fixtures included in the Interests,  to
the extent that  Seller has the legal right to grant such access and right.  All
visits to Seller's facilities by Buyer, and on Buyer's behalf, will be scheduled
by mutual consent of the Parties,  subject to Buyer's  providing Seller at least
five days  written  notice of the  locations  that Buyer wishes to visit and the
proposed times. Seller may accompany Buyer and its representatives  during their
site  visits.  Entry onto the  Interests  will (i) subject  Buyer to third party
restrictions,  if any, and to Seller's industrial safety,  hygiene, and drug and
alcohol requirements and (ii) be at Buyer's sole risk and expense.


                                       9


         5.03  Environmental  Assessment.  Buyer may  conduct  an  environmental
assessment of the Interests,  including  investigations to identify wetlands and
sensitive  and  protected   habitats.   If  Buyer  undertakes  an  environmental
assessment,  both the consultant (if  consultants are employed) and the scope of
the proposed  assessment,  including  testing  protocols,  must be acceptable to
Seller  before the work may begin.  If Buyer and Seller  cannot agree on Buyer's
proposed  environmental  assessment  plan,  then Seller may at its sole  option,
withdraw from this Agreement any of the Interests that Buyer proposes to assess,
or all of the  Interests,  and the  Purchase  Price  will be  adjusted  for each
withdrawn  Interest.  If Seller  withdraws  all the  Interests  pursuant to this
Section,  this Agreement will  terminate,  and Seller will refund the Deposit to
Buyer.

If Buyer takes samples from the Interests,  Seller may require splitting of each
sample. Buyer will deliver copies of all draft and final reports, results, data,
and analyses of site visits, inspections,  and assessments to Seller within five
days  of  Buyer's  receipt  of  them,  at  Buyer's  cost.  Seller  will  have no
confidentiality  obligation with regard to this  information and may disclose it
to third parties or use it for any purpose.

Notwithstanding  anything in the foregoing that may appear to the contrary,  the
presence  of  naturally  occurring   radioactive  materials  ("NORM")  will  not
constitute a Title Defect (hereinafter defined). IT IS EXPRESSLY RECOGNIZED THAT
THE LANDS AND/OR WATER  BOTTOMS  ALONG WITH SURFACE  FACILITIES  AND  PRODUCTION
EQUIPMENT  LOCATED  THEREON,  HAVING  BEEN USED IN  CONNECTION  WITH OIL AND GAS
PRODUCTION  ACTIVITIES,  MAY  CONTAIN  NORM AS A  RESULT  OF  THESE  OPERATIONS.
ACCORDINGLY,   LANDS  AND/OR  WATER  BOTTOMS,   THE  WELLS,  AND  THE  EQUIPMENT
TRANSFERRED  HEREIN ARE TRANSFERRED  WITH THE RESTRICTION THAT THEY WILL BE USED
ONLY IN CONNECTION  WITH OIL AND GAS PRODUCING  ACTIVITIES  ASSOCIATED  WITH THE
LEASES, AND WILL NOT BE SUBSEQUENTLY TRANSFERRED FOR UNRESTRICTED USE UNLESS THE
CONCENTRATIONS  OF NORM ASSOCIATED  THEREWITH ARE BELOW THE LEVELS  SPECIFIED AS
ALLOWABLE FOR UNRESTRICTED TRANSFER AS SET FORTH IN ANY AND ALL APPLICABLE LAWS,
ORDERS,  RULES  OR  REGULATIONS  OF ANY  GOVERNMENTAL  AGENCY  OR  COURT  HAVING
JURISDICTION.  ADDITIONALLY,  BUYER AGREES TO COMPLY WITH ALL PROVISIONS OF SUCH
LAWS, ORDERS RULES OR REGULATIONS APPLICABLE TO SAID LANDS AND/OR WATER BOTTOMS,
THE WELLS,  AND THE  PERSONAL  PROPERTY.  BUYER  FURTHER  AGREES TO INCLUDE  THE
PROVISIONS OF THIS CLAUSE IN ANY  SUBSEQUENT  SALE OR ASSIGNMENT OF ANY INTEREST
THEREIN TRANSFERRED.

         5.04 Gas Imbalance. Upon the occurrence of Closing, but effective as of
the  Effective  Time,  Buyer shall  succeed to and assume the position of Seller
with  respect  to all gas  imbalances  and  make-up  obligations  related to the
Interests (regardless of whether such imbalances or make-up obligations arise at
the  wellhead,  pipeline,  gathering  system or other level,  and  regardless of
whether  the same  arise  under  contract  or  otherwise).  As a result  of such
succession,  Buyer shall (i) be entitled to receive any and all  benefits  which
Seller  would  have  been  entitled  to  receive  by  virtue  of  such  position


                                       10


(including,  without  limitation,  rights to  produce  and  receive  volumes  of
production in excess of volumes which it would  otherwise be entitled to produce
and  receive by virtue of  ownership  of the  Interest  rights to  receive  cash
balancing payments), and (ii) be obligated to suffer any detriments which Seller
would  have been  obligated  to suffer  by virtue of such  position  (including,
without limitation, the obligation to deliver to others production volumes which
would have otherwise  been  attributable  to its ownership of the Interests,  to
deliver production to purchasers hereof without receiving full payment therefor,
or to make cash  balancing  payments or to repay take or pay payments) and (iii)
shall be responsible  for any and all royalty  obligations  with respect to such
imbalances  (including,  without  limitation,  any of the  same  arising  out of
royalties having been paid on an  "entitlements"  basis rather than a "receipts"
basis).

         5.05 Title Defects. "Title Defect" means any encumbrance,  irregularity
or defect in Seller's title to an Interest which , alone or in combination  with
other defects,  causes  Seller's title to be less than Defensible  Title.  Title
Defects  shall  include a Casualty  Loss treated as a Title Defect under Section
5.07.

         5.06 Defensible Title.

                  (a)  "Defensible  Title"  means such right,  title or interest
         held by Seller that (i) will entitle Buyer, as Seller's  successor,  to
         receive not less than the Net Revenue Interests  described in Exhibit A
         of all oil, gas,  condensate,  related  hydrocarbons and other minerals
         produced under the terms of the Leases (or other  property  denominated
         in Exhibit A); (ii) will obligate Buyer, as Seller's  successor to bear
         a  percentage  of  costs  and  expenses  related  to  the  maintenance,
         operation and development of the Leases (or other property  denominated
         in Exhibit A) not  greater  than the  Working  Interest  (or  Operating
         Rights  interest,  as the case may be) shown in Exhibit  A,  unless the
         circumstances causing the Working Interest to be greater will cause the
         corresponding  Net Revenue interest to increase in the same proportion;
         and (iii) is free of all liens,  security  interests,  encumbrances and
         defects, except for Permitted Encumbrances.

                  (b) "Permitted Encumbrances" are:

                           (1)   lessor's   royalties,   overriding   royalties,
                  production  payments,  net  profits,  interests,  reversionary
                  interests and similar  burdens on production  that do not, and
                  will not, reduce the Interests more particularly  described in
                  the  Assignments  of Record  Title,  Assignments  of Operating
                  Rights  and  Assignments  of  Overriding   Royalty   Interests
                  attached hereto as Exhibits B-1 through B-12;

                           (2)  preferential  rights to purchase and third party
                  consents with respect to which, prior to Closing,  (i) waivers
                  or consents are obtained from the appropriate  parties or (ii)
                  the  time  for  asserting  such  rights  has  expired  without
                  exercise;

                           (3) mechanics',  materialmen's,  operators',  tax and
                  similar  liens or charges  arising in the  ordinary  course of
                  business related to an Interest, if such liens secure payments
                  not yet due;


                                       11


                           (4) all consents  from,  notices to,  approvals by or
                  other actions by  governmental  authority in  connection  with
                  sale or transfer of  properties  such as the Interests if such
                  matters are customarily and  appropriately  obtained after the
                  sale or transfer;

                           (5) liens,  security  interests or other encumbrances
                  to be released at or prior to Closing;

                           (6)  rights of a  governmental  entity to  control or
                  regulate the  Interests,  together with all  applicable  laws,
                  rules and regulations;

                           (7)  easements,  rights-of-way,  surface  leases  and
                  other surface use restrictions if such  restrictions  will not
                  materially adversely affect the use, value or operation of the
                  Interests;

                           (8)  title  matters  waived or deemed to be waived by
                  Buyer and described on Schedule 5.06(b)(8);

                           (9) the presence of NORM; and

                           (10) the Contracts

         5.07  Casualty  Loss.  If,  prior to Closing,  all or any portion of an
Interest  is  destroyed  or taken under the right of eminent  domain  ("Casualty
Loss"), Buyer may elect (i) to treat the Casualty Loss as a Title Defect or (ii)
purchase the affected  Interest  notwithstanding  the Casualty Loss. If Buyer so
purchases  the  affected  Interest,  there shall be no reduction of the Purchase
Price and Seller shall,  at Closing,  pay to Buyer all sums paid to Seller which
are associated  with the Casualty Loss and shall assign to Buyer all of Seller's
interest in any unpaid payments or causes of action associated with the Casualty
Loss.  Prior to Closing,  Seller shall not  compromise or settle a Casualty Loss
without Buyer's consent.

         5.08 Disposition of Title Defects. In the event that Buyer gives Seller
notice of Title Defects:


                  (a) Seller may (but shall have no  obligation  to)  attempt to
         cure, prior to Closing, Title Defects.

                  (b)  Whether or not  Seller has then begun to, or ever  begins
         to, cure  asserted  Title  Defects,  Seller may postpone the Closing by
         designating  a new  Closing  Date to be a date not  later  than 30 days
         after  Seller's  receipt of a Defect notice.  Notwithstanding  any such
         election to postpone  Closing,  there shall still be no  obligation  to
         cure Title Defects.


                                       12


                  (c) Notwithstanding any other election made under this Section
         (without  limitation,  it being  expressly  recognized that attempts to
         cure asserted  Title Defects may continue  while the parties are acting
         under this  election),  Seller  may elect to have one or more  asserted
         Title Defects handled under the following Section.

         5.09 Purchase Price Adjustments.

                  (a) Except as provided in Section  5.09(b) below, in the event
         that,  as a part of Buyer's due  diligence  review,  Title  Defects are
         presented  to Seller and Seller is unable (or  unwilling)  to cure such
         Title Defects prior to Closing, then:

                           (i) Buyer and  Seller  shall,  with  respect  to each
                  Interests  affected by such matters,  attempt to agree upon an
                  appropriate  adjustment  of the Purchase  Price to account for
                  such matters; and

                           (ii) with  respect to Interests as to which Buyer and
                  Seller are unable to agree upon an adjustment  for an asserted
                  Title  Defect,  such  Interests  will  be  excluded  from  the
                  transaction contemplated hereby and the Purchase Price will be
                  reduced by the amount  attributed  to such Interest on Exhibit
                  A; provided,  however, in the event an adjustment is required,
                  pursuant  to  this  paragraph,  but  such  Interest  is  to be
                  excluded  as  provided   herein,   Seller  may,  at  its  sole
                  discretion,  elect to not  close  and such  election  shall be
                  considered  as a failure to close that is permitted in Section
                  6.01 hereof.

                  (b) If an asserted Title Defect reflects (or Seller  otherwise
         determines)  that Seller's share of Substances  produced and saved from
         the Leases  comprising an Interest is less than,  or greater than,  the
         decimal  share set forth as the Net  Revenue  Interest  in Exhibit A or
         causes  Seller to be  obligated  to pay a share of costs of  operations
         greater  than the  percentage  share of Working  Interest  set forth on
         Exhibit A hereof  (without  at least a  proportionate  increase  in the
         corresponding  Net Revenue  Interest)  then the Purchase  Price for the
         Interest  shall be  adjusted  downward,  or  upward as the case may be,
         proportionately,  by multiplying  such Purchase Price by a fraction (A)
         the numerator of which is the amount of the actual Net Revenue Interest
         and (B) the  denominator of which is the Net Revenue  Interest shown on
         Exhibit A.

                  (c) If the aggregate  Purchase  Price  reduction (or increase)
         with  respect to a Title  Defect,  which  would  result  from the above
         provided for procedure does not exceed $5,000,  no adjustment  shall me
         made for such Title Defects,  and the Interests  affected  thereby will
         not be excluded as a result of the existence of such Title  Defect.  If
         the Purchase Price  reduction (or increase) which would result from the
         above provided for procedure, as applied to all Title Defects for which
         an adjustment  is to be made,  does not exceed five percent (5%) of the
         Purchase  Price,  then no adjustment of the Purchase Price shall occur,
         and none of the  Interests  which would be  otherwise  excluded by such
