                  legal files, computer programs, general tax records, samples,
                  test data or any other data, information or documents
                  unrelated to the Leasehold Property. This Agreement by Seller
                  to convey the aforementioned records is granted by Seller to
                  the extent that Seller has authority to do so without
                  violating any confidentiality or license obligations to a
                  third party, all of which are disclosed on SCHEDULE 1.3, and

                  this Agreement to the contrary, Seller shall not provide
                  Purchaser with any records or data which Seller considers to
                  be interpretive, proprietary or confidential to it or which
                  Seller cannot legally provide to Purchaser because of third
                  party restrictions on Seller.

                  All of the foregoing rights, interests and properties are
                  hereinafter collectively referred to as the "Assets."

10:00 a.m. on March 14, 1996 (the "Closing Date"), at Seller's office or at such
other place, date and time as may be mutually agreed upon by Seller and
Purchaser.

         1.3      ASSUMPTION OF OBLIGATIONS: From and after the Closing Date,
Purchaser shall assume, pay for, discharge, be responsible for, perform and

of any permit, statute, rule, regulation or order of any governmental authority.

ownership of all the Assets and production produced from and after the Effective
Date attributable to the Leasehold Property conveyed to Purchaser shall pass to
Purchaser as of the Effective Date.

                                       II.

                  taxes) in each case;

         (e)      Less the amount of the proceeds received by Seller that are
                  attributable to the Assets after the Effective Date, net of
                  any royalties, other lease burdens and any production,
                  severance or sales taxes not reimbursed to Seller by the
                  purchaser of such production;

         (f)      Less the amount equal to all unpaid ad valorem, property,

                  proceeds therefrom accruing to the Leasehold Property that are

                  Effective Date;

         (g)      Less any amounts received by Seller (whether prior to or
                  subsequent to the Effective Date) with respect to the Assets
                  conveyed to Purchaser at Closing pursuant to take-or-pay,

                  its preferential purchase right with respect to High Island
                  Block 45 and (z) the date that the Title Defects, if any, with
                  respect to High Island Block 45 and South Marsh Island Block
                  133 have been resolved in accordance with Section 3.5 hereof,

                                      -6-

         2.5      PAYMENT OF ADJUSTED PURCHASE PRICE: Seller shall prepare and
                  furnish to Purchaser at least three (3) business days prior to
                  Closing a preliminary closing statement setting forth the
                  adjustments to the Purchase Price and the Adjusted Purchase
                  Price to be paid by Purchaser at Closing. Such closing
                  statement shall reflect each adjustment and the calculation
                  used to determine such amount. At Closing, Purchaser shall pay
                  to Seller the Adjusted Purchase Price by wire transfer of cash
                  in United States currency in a manner specified by Seller to
                  Purchaser at least two (2) business days prior to Closing.

                                TITLE EXAMINATION

         3.1      ACCESS TO TITLE INFORMATION: After the date of this Agreement 
     and until Closing, at Purchaser's request, Seller shall make the records
     described in Section 1.1(f) available to Purchaser at Seller's offices,
     during normal business hours for examination by Purchaser. Seller shall
     provide Purchaser's authorized representatives with office space as
     reasonably necessary for due diligence purposes. Subject to the consent and
     cooperation of operators and other third parties, Seller will cooperate
     with Purchaser in Purchaser's efforts to obtain, at Purchaser's sole
     expense, such additional information relating to the Assets as Purchaser
     may reasonably desire, to the extent in each case that Seller may do so
     without violating any confidentiality or license obligations or other
     contractual commitments to a third party. Seller shall cause its personnel
     to assist Purchaser in obtaining such additional information (other than
     interpretative information) and shall use reasonable commercial efforts to
     cause the counsel, accountants, independent petroleum consultants and
     engineers, employees and other representatives of Seller to be available to
     Purchaser for such purposes. During such investigation, except as
     prohibited by confidentiality or license obligations or other contractual
     commitments to a third party (with respect to which Seller shall use
     reasonable commercial efforts to obtain a waiver thereof for the benefit of
     Purchaser), Purchaser shall have the right to make copies of such records,
     files and other materials as Purchaser may reasonably deem advisable.
     Seller shall not be obligated to perform any additional title work, and any
     additional abstracts and title opinions will not be made current by Seller.
     EXCEPT AS SPECIFICALLY PROVIDED IN THIS AGREEMENT, NO WARRANTY OF ANY KIND
     IS MADE BY SELLER AS TO THE INFORMATION SO SUPPLIED, AND PURCHASER AGREES
     THAT ANY CONCLUSIONS DRAWN THEREFROM SHALL BE THE RESULT OF ITS OWN
     INDEPENDENT REVIEW AND JUDGMENT.

                                      -7-

         3.2      TITLE DEFECTS:   For the purpose of this  Agreement,  a 
     "Title Defect" shall mean one or more of the following:

         (a)      Seller's title at the Effective Date, as to one or more of the
                  Assets, is not of record, or is subject to an outstanding
                  mortgage, deed of trust, lien or encumbrance that is neither
                  specifically listed or referenced in this Agreement or on an
                  exhibit attached hereto, nor considered a Permitted
                  Encumbrance (as hereinafter defined);

         (b)      Seller's  interest  in any of the  Assets  is  more  or  less 
                  (but not by way of any Permitted Encumbrances) than
                  represented on EXHIBIT A hereto;

         (c)      Seller's rights and interests in any of the Assets are subject
                  to (i) any contract or agreement not listed on SCHEDULE 1.3 or
                  (ii) being reduced by virtue of the exercise by a third party
                  of a reversionary, back-in or similar right not specifically
                  listed or referenced in this Agreement or on an exhibit
                  attached hereto, nor considered a Permitted Encumbrance;

         (d)      Seller is in default under some material provision of a lease,
                  farmout agreement, joint operating agreement, gas balancing
                  agreement, gas sales contract or other material contract or
                  agreement affecting the Assets; or

         (e)      Any of Seller's representations set forth in Sections 6.9
                  through 6.21, insofar as it relates to any particular Asset,
                  is untrue in any material respect.

         3.3      PERMITTED ENCUMBRANCES:   "Permitted  Encumbrances,"  as that 
     term  is  used in this  Agreement, means:

         (a)      Liens for taxes not yet delinquent;

         (b)      Lessors' royalties, overriding royalties, reversionary
                  interests and other lease burdens that do not operate to
                  reduce the net revenue interest of Seller in any of the Assets
                  to less than the amount set forth therefor on EXHIBIT A;

         (c)      Contracts and agreements that (i) are disclosed on SCHEDULE
                  1.3 and (ii) do not operate to increase the working interest
                  or decrease the net revenue interest of Seller in any of the
                  Assets from that set forth on EXHIBIT A;

         (d)      Rights of way, surface leases and other agreements of a
                  similar nature relating to or restricting surface use on, over
                  or in respect of the Assets that 

                                      -8-

                  do not have a material adverse effect on the ownership, use,
                  operation or value of such Assets;

         (e)      Preferential rights to purchase which, prior to Closing, have
                  either expired or have been waived by the holders thereof to
                  the extent such rights affect the Assets;

         (f)      All necessary consents, permissions and approvals by third
                  parties in connection with the sales and transfer of the
                  Assets which have been obtained unconditionally prior to
                  Closing and those governmental consents customarily generated
                  and received in the ordinary course of business at a
                  post-Closing date;

         (g)      Such Title Defects or other deficiencies or irregularities 
                  waived by Purchaser in writing;

         (h)      Liens or encumbrances released at or prior to Closing as
                  disclosed on SCHEDULE 3.3(H) attached hereto, provided that
                  valid releases are obtained and presented to Purchaser at
                  Closing pursuant to clause (f) of Article VIII herein; and

         (i)      Rights reserved to or vested in any governmental subdivision,
                  political entity or public authority to control or regulate
                  the Assets in any manner, and all applicable laws, rules and
                  orders of such subdivisions, entities and authorities,
                  provided that such governmental rights, laws, rules and orders
                  do not have a material adverse effect on the ownership, use,
                  operation or value of such Assets.

         3.4      NOTICE OF TITLE DEFECT: Upon discovery of a Title Defect, the
     discovering party shall immediately notify the other party in writing of
     the nature of the Title Defect and the proposed adjustment in the Purchase
     Price attributable to such Title Defect. Any Title Defect which might serve
     as the basis of a reduction in the Purchase Price that is not disclosed to
     Seller at least five (5) business days prior to Closing shall conclusively
     be deemed waived by Purchaser, but only for purposes of Section 3.5 below.
     Purchaser's failure to give notice of Title Defects pursuant to this
     Section 3.4 shall not prejudice or diminish in any respect Purchaser's
     rights under Section 9.2(b) herein and the Assignments to be delivered by
     Seller on the Closing Date.

                                      -9-

     3.5          REMEDIES FOR TITLE DEFECT:

         (a)      Upon timely delivery of notice of a Title Defect either by
                  Purchaser or by Seller, Purchaser and Seller shall meet and
                  use their best efforts to agree on the validity of the claim
                  and the amount of any required Purchase Price adjustment.
                  Purchase Price adjustments, shall be determined in accordance
                  with the following guidelines:

                  (i)      If it is determined that Seller owns a different
                           interest than that shown on EXHIBIT A, then the
                           Purchase Price shall be reduced or increased, as
                           appropriate.

                  (ii)     In the event a third party or parties elect to
                           exercise an applicable preferential right of
                           purchase, the Purchase Price shall be reduced by the
                           amount allocated to the affected property as
                           indicated on the Allocation of Value (EXHIBIT B
                           hereto), and Closing shall occur as to the remainder
                           of the properties, if any.

                  (iii)    If a Title  Defect  is a lien,  encumbrance  or  
                           other charge which is liquidated in amount, then the
                           adjustment shall be the sum necessary to be paid to
                           the obligee to remove the Title Defect from the
                           affected property and Seller shall pay such sum to
                           obligee at or before Closing. Purchaser agrees to
                           cooperate with Seller in such efforts at no risk or
                           expense to Purchaser. If a Title Defect represents an
                           obligation or burden upon the affected property for
                           which the economic detriment to Purchaser can be
                           estimated with reasonable certainty, the adjustment
                           shall be the sum necessary to compensate Purchaser at
                           Closing for the adverse economic effect which such
                           Title Defect will have on the affected property.

                  (iv)     If the parties cannot agree on the amount of a
                           Purchase Price adjustment attributable to a Title
                           Defect asserted by Purchaser, notwithstanding the
                           foregoing guidelines, or as to the existence of a
                           Title Defect asserted by Purchaser, the affected
                           property will be eliminated from the purchase and
                           sale transaction contemplated by this Agreement and
                           the Adjusted Purchase Price shall reflect a reduction
                           by the amount allocated to the affected property as
                           indicated on the Allocation of Value (EXHIBIT B
                           hereto), and Closing shall occur as to the remainder
                           of the properties, subject to Section 3.5(b).

                                      -10-

         (b)      In the event the net amount of all adjustments to the Purchase
                  Price pursuant to Section 3.5(a) (other than an adjustment
                  under Section 3.5(a)(ii) necessitated by the exercise by Santa
                  Fe Energy Resources, Inc. or Hardy Oil & Gas USA Inc., as the
                  case may be, of a preferential purchase right with respect to
                  High Island Block 45) exceeds twenty percent (20%) of the
                  total Purchase Price, then Seller or Purchaser may, upon
                  written notice to the other party, terminate this Agreement,
                  and the same shall be of no further force and effect.

         (c)      If  Purchaser  is  entitled  to receive an  adjustment  for a 
                  Title Defect, as provided in this Agreement, Seller shall have
                  the right, but not the obligation, to attempt to cure the
                  Title Defect and cancel the reduction in the Purchase Price.
                  If Seller chooses to cure the Title Defect, but has not done
                  so by Closing, Seller shall have the right to postpone Closing
                  with respect to the affected property for a period not to
                  exceed twenty (20) business days from the original Closing
                  Date (the "Cure Period"). During the Cure Period, Seller shall
                  remain the record and beneficial owner thereof and shall
                  continue to conduct operations of the affected property in a
                  good and workmanlike manner, subject to the provisions of
                  Article V hereof. On or before the last day of the Cure
                  Period, Seller may submit to Purchaser such curative materials
                  as Seller has obtained with respect to any uncured and
                  unwaived Title Defect existing as of the Closing Date, and
                  Purchaser will have twenty (20) business days to review and
                  approve or reject the same. If Purchaser approves, Purchaser
                  will accept, pay for in accordance with the Allocation of
                  Value (EXHIBIT B hereto), as adjusted if necessary under the
                  guidelines stated in Section 3.5(a) hereof, and receive an
                  assignment of the property as to which Seller has cured a
                  Title Defect. If at the end of the Cure Period, Seller shall
                  not have removed any applicable Title Defect, Purchaser shall
                  have the right to elect (i) to waive such Title Defect and
                  accept, pay for and receive an assignment of the affected
                  property or (ii) to eliminate the affected property from the
                  purchase and sale transaction contemplated by this Agreement,
                  in which case the Adjusted Purchase Price shall reflect a
                  reduction by the amount allocated to the affected property as
                  indicated on the Allocation of Value (EXHIBIT B hereto).
                  

         3.6      PREFERENTIAL PURCHASE RIGHTS: Except as disclosed on SCHEDULE 
     3.6 attached hereto, none of the Leasehold Property is subject to
     preferential purchase rights or consents to assignment in favor of third
     parties. With respect to each preferential purchase right covering the
     Leasehold Property, Seller shall send to the holder of such right a notice
     offering to sell to such holder, in accordance with the contractual
     provisions applicable to such right, those Assets covered by such right on

                                      -11-

     substantially the same terms hereof and for the portion of the Purchase
     Price attributable to such Leasehold Property on the Allocation of the
     Value (EXHIBIT B attached hereto), subject to adjustments in the same
     manner as the Purchase Price may be adjusted pursuant to Section 3.5 of
     this Agreement.

         If, prior to Closing, any holder of a preferential purchase right
     notifies Seller that it intends to consummate the purchase of the Assets to
     which its preferential purchase right applies, then those Assets shall be
     excluded from the Assets to be conveyed to Purchaser, and the Purchase
     Price shall be reduced as set forth in Section 3.5(a)(ii); provided,
     however, that if the holder of such preferential purchase right fails to
     consummate the purchase of the Assets covered by such right in accordance
     with and within the time provided in the applicable agreement, then Seller
     shall so notify Purchaser, and at Closing, Seller shall sell to Purchaser,
     and Purchaser shall purchase from Seller, the Assets to which the
     preferential purchase right is applicable for a price equal to that portion
     on the Allocation of Value and upon the other terms of this Agreement.

         3.7      CONSENTS TO ASSIGNMENT: Seller shall use reasonable commercial
     efforts to obtain all consents to assignment of the Assets prior to
     Closing. If a lessor or other third party who has the right to consent to
     assignment of an Asset or part thereof refuses such consent or refuses to
     grant a consent on an unconditional basis, or if such party fails to
     respond to Seller's efforts to obtain consent to assignment, Seller will
     promptly notify Purchaser, such notice to be provided at least five (5)
     business days prior to Closing. Any Asset or part thereof so affected on
     the Closing Date will be deemed to be subject to an uncured Title Defect.


                                       IV.

                               PHYSICAL CONDITION

         4.1 PHYSICAL CONDITION OF THE ASSETS: Purchaser acknowledges that some
     oil field production equipment may contain asbestos and/or
     naturally-occurring radioactive material ("NORM"). In this regard,
     Purchaser expressly understands that NORM may affix or attach itself to the
     inside of wells, materials and equipment as scale or in other forms, and
     that wells, materials and equipment located on the Assets described herein
     may contain NORM and that NORM-containing materials may be buried or have
     been otherwise disposed of on or under the Assets. Purchaser also expressly
     understands that special procedures may be required for the removal and
     disposal of asbestos and NORM from the Assets where it may be found, and
     that

                                      -12-

     Purchaser assumes all liability and responsibility for such activities when
     and if performed but without prejudice to Purchaser's rights under Sections
     4.6, 9.2 and 12.18 hereof.

         4.2      ENVIRONMENTAL ASSESSMENT DURING EXAMINATION PERIOD:

         (a)      Upon  Purchaser's  execution  of  this  Agreement,   Seller  
                  will make available to Purchaser environmental reports or
                  surveys, if any, in Seller's possession pertaining to any of
                  the Assets, and Purchaser shall have the right to make any
                  environmental assessment of the Assets during the period (the
                  "Examination Period") beginning on the date of this Agreement
                  and ending five (5) days prior to Closing. Purchaser and its
                  Agents (as such term is defined in Section 4.6) shall have the
                  right to enter upon the Assets and all buildings and
                  improvements thereon, inspect the same, conduct soil and water
                  tests and borings, and generally conduct such tests,
                  examinations, investigations and studies as may be necessary
                  or appropriate for the preparation of appropriate engineering
                  and other reports, and evaluations relating to the Assets,
                  their condition, and the presence of waste or contaminants.
                  Purchaser agrees to immediately provide to Seller a copy of
                  the environmental assessment, including any reports, data and
                  conclusions upon which it is based. Except as may be required
                  by law, subpoena or other legal process, Purchaser agrees to
                  keep all data and information acquired by virtue of such
                  examinations, and the results of all testing and analyses
                  thereof, strictly confidential and not to disclose same to any
                  person or agency, without the prior written approval of
                  Seller, other than (i) Purchaser's Agents and (ii) firms or
                  entities proposing to provide financial accommodations to
                  Purchaser.

         (b)      ON-SITE TESTS AND INSPECTIONS: Seller shall permit, or in case
                  of any third-party operated wells, use reasonable commercial
                  efforts to cause the operator thereof to permit, Purchaser's
                  authorized representatives to consult with Seller's and/or
                  such third-party operator's agents and employees during
                  reasonable business hours and to conduct on-site inspections
                  and inventories of the Leasehold Property and inspect and
                  examine all well logs and geological and geophysical data
                  (other than interpretive information) directly relating to
                  such Leasehold Property.

                                      -13-

     4.3 WITHDRAWAL BY PURCHASER:

         (a)      If, during the  Examination  Period,  Purchaser,  in its sole
                  discretion determines that (i) an Environmental Defect or
                  Defects exists, or (ii) that the physical inspections
                  contemplated by Section 4.2(b) indicate (x) that any Asset may
                  not be in compliance in any material respect with any
                  applicable laws, rules or regulations or (y) that any well
                  included in the Assets has suffered a material adverse change
                  since November 30, 1995 in its ability to produce hydrocarbons
                  then, by so notifying Seller within the Examination Period,
                  Purchaser may eliminate any Asset affected by an Environmental
                  Defect, material non-compliance or material adverse change
                  from the purchase and sale transaction and the Purchase Price
                  shall be reduced by the amount allocated to the affected
                  property as indicated on the Allocation of Value (EXHIBIT B
                  hereto), and Closing shall occur as to the remainder of the
                  properties, subject to Section 3.5(b).

         (b)       An "Environmental Defect" shall mean, with respect to any
                   Asset:

                   (i)     Any matter that causes a breach of Seller's
                           representation  set forth in Section 6.19; or

                   (ii)    With respect to an environmental assessment conducted
                           pursuant to Section 4.2(a) hereof, the presence or
                           evidence of the past presence of any Hazardous
                           Substance on the Leasehold Property. A "Hazardous
                           Substance" is any substance, chemical or waste that
                           is listed or included as hazardous, toxic or
                           dangerous under any applicable Environmental Laws (as
                           such term is defined in Section 6.19 hereof).

         4.4      CONDITIONAL ACCESS TO ASSETS:  Purchaser  is hereby  granted
access to the Assets to conduct its environmental assessment and physical
inspections and tests upon the following conditions:

         (a)      The environmental assessment and physical inspections and
                  tests shall be conducted at Purchaser's sole risk and expense,
                  and Purchaser waives and releases all claims against Seller
                  and its Agents for injury to, or death of, persons or damage
                  to property arising in any way from the exercise of rights
                  granted to Purchaser hereby or the activities of Purchaser or
                  its employees, Agents or contractors on the Assets.

                                      -14-

         (b)      Purchaser  shall  indemnify  Seller,  and  its  Agents
                  against and hold each and all of said indemnitees harmless
                  from any and all loss, cost, damage, expense or liability,
                  including attorneys' fees, whatsoever arising out of (i) any
                  and all liens or other encumbrances for labor or materials
                  furnished in connection with such tests, samplings, studies or
                  surveys as Purchaser may conduct with respect to the Assets
                  and (ii) any injury to or death of persons or damage to
                  property occurring in, on or about the Assets as a result of
                  such exercise or activities whether or not Seller or its
                  Agents were negligent or otherwise at fault (except for any
                  such injuries or damages caused solely by the gross negligence
                  or willful misconduct of said indemnitees).

         4.5      [Intentionally omitted.]

         4.6      ASSUMPTION AND INDEMNIFICATION OF ENVIRONMENTAL RISK:

         (a)      On and after the Closing  Date,  Purchaser  shall assume full
                  responsibility for, and agrees to comply with and perform all
                  environmentally related duties and obligations of the owner of
                  the Assets arising from the ownership or operation thereof
                  after the Closing Date, and to indemnify, defend and hold
                  harmless Seller, its directors, officers, employees, agents,
                  representatives and affiliated companies (which additional
                  parties are hereinafter collectively referred to as "Agents"),
                  from and against all losses, liabilities, causes of action,
                  damages, liens, penalties, fines, settlement, judgments,
                  expenses, attorneys' fees, court costs and claims (hereinafter
                  referred to collectively as "Claims") caused by or arising out
                  of Purchaser's (or Purchaser's successors or assigns) failure
                  to observe or comply with any rule, order, permit, statute or
                  regulation of a governmental authority applicable to any waste
                  material, contaminant or Hazardous Substance on or included
                  with the Assets as a result of operations on or after the
                  Closing Date or the disposal, release or threatened release on
                  or after the Closing Date of any waste material, contaminant
                  or Hazardous Substance from the Assets into the atmosphere or
                  into or upon land or any water course or body of water,
                  including ground water.

         (b)      Seller shall indemnify, defend and hold harmless Purchaser and
                  its Agents from and against Claims made within two (2) years
                  of the Closing Date caused by or arising out of (i) the
                  performance prior to the Closing Date of environmentally
                  related duties and obligations of the owner of the Assets,
                  (ii) Seller's failure to have observed or complied with any
                  rule, order,

                                      -15-

                  permit, statute, or regulation of a governmental authority
                  applicable to any waste material, contaminant or Hazardous
                  Substance on or included with the Assets as a result of
                  operations prior to the Closing Date or (iii) the disposal,
                  release or threatened release prior to the Closing Date of any
                  waste material, contaminant or Hazardous Substance from the
                  Assets into the atmosphere or into or upon land or any water
                  course or body of water, including ground water; provided,
                  however, in no event shall Seller have any obligation to
                  indemnify, defend or hold harmless Purchaser against such
                  Claims attributable to Purchaser's negligence in remediating
                  any environmental condition existing prior to the Closing
                  Date.

         (c)      Purchaser  shall  indemnify,  defend and hold harmless Seller 
                  and its Agents from and against all Claims made after two (2)
                  years from the Closing Date caused by or arising out of (i)
                  the performance prior to the Closing Date of environmentally
                  related duties and obligations of the owner of the Assets,
                  (ii) the failure, prior to the Closing Date, of the owner or
                  operator of the Assets to have observed or complied with any
                  rule, order, permit, statute or regulation of a governmental
                  authority applicable to any waste material, contaminant or
                  Hazardous Substance on or included with the Assets or (iii)
                  the disposal, release or threatened release prior to the
                  Closing Date of any waste material, contaminant or Hazardous
                  Substance from the Assets into the atmosphere or into or upon
                  land or any water course or body of water, including ground
                  water; provided, however, in no event shall Purchaser have any
                  obligation to indemnify, defend or hold harmless Seller
                  against (i) such Claims attributable to matters of which
                  Seller had actual knowledge at the Closing Date and failed to
                  disclose to Purchaser, including without limitation such
                  matters as would cause a breach of Seller's representations
                  set forth in Section 6.19, or (ii) such Claims attributable to
                  or caused by Seller's own actions or omissions whenever they
                  occurred.

         (d)      Notwithstanding  Section 4.6(c),  Seller shall indemnify,  
                  defend and hold harmless Purchaser and its Agents from and
                  against all Claims made after two (2) years from the Closing
                  Date caused by or arising out of (i) the performance prior to
                  the Closing Date of environmentally related duties and
                  obligations of the owner of the Assets, (ii) the failure,
                  prior to the Closing Date, of the owner or the operator of the
                  Assets to have observed or complied with any rule, order,
                  permit, statute, or regulation of a governmental authority
                  applicable to any waste material, contaminant or Hazardous
                  Substance on or included with the Assets, or (iii) the
                  disposal, release, or threatened release prior to the Closing
                  Date of any waste material, contaminant, or Hazardous
                  Substance from the Assets into the 

                                      -16-

                  atmosphere or into or upon any land or water course or body of
                  water, including ground water, to the extent but only to the
                  extent that such Claims are attributable to matters of which
                  Seller had actual knowledge at the Closing Date and failed to
                  disclose to Purchaser.

         (e)      This  indemnification  and  assumption of  responsibility  
                  shall apply to liability for voluntary environmental response
                  actions undertaken pursuant to the Comprehensive Environmental
                  Response Compensation and Liability Act ("CERCLA") or any
                  other federal, state or local law, regulation or order. A
                  Claim shall be deemed asserted against Seller at the time an
                  inquiry or investigation of which Seller has actual knowledge
                  is initiated by any regulatory agency or judicial body having
                  jurisdiction thereover relating to environmental cleanup or
                  remediation activities or upon Seller's receipt of written
                  demand for environmental cleanup or remediation activities
                  from an affected lessor.

                          OPERATIONS AND CASUALTY LOSS

         5.1      OPERATIONS:

         (a)      Seller, as to the portion of the Assets to be conveyed
                  which it now operates, agrees to continue to operate the same
                  in a good and workmanlike manner until Closing, when such
                  operations shall be turned over to Purchaser unless contrary
                  to applicable unit, pooling, communitization or operating
                  agreements or applicable laws and/or regulations or unless
                  Seller and Purchaser otherwise agree. Subject to the
                  provisions of Section 5.2(b), Seller shall pay or cause to be
                  paid all costs and expenses incurred in connection therewith
                  until the Closing Date. Except as provided for elsewhere in
                  this Agreement, Seller shall not directly or indirectly convey
                  to a third party, or reserve or retain, any recorded or
                  unrecorded interest in any of the Leases, and Seller shall not
                  convey to a third party, or reserve or retain, any recorded or
                  unrecorded executory rights. During the period, if any, from
                  and after the Closing Date until Seller is replaced as
                  operator, Seller as operator of the Assets shall have no
                  liability to Purchaser for losses or damages sustained or
                  liabilities incurred, except as may result directly from
                  Seller's gross negligence or willful misconduct. In no event
                  shall Seller be replaced as operator of the Assets at any time
                  prior to 

                                      -17-

                  Closing. In the absence of any applicable operating agreement
                  for any such services, if any, as operator of the Assets (or
                  portions thereof) performed by Seller from and after the
                  Closing Date, Purchaser shall pay to Seller all reasonable and
                  customary expenses incurred by Seller in such operation,
                  protection or maintenance of the Assets and, in addition, for
                  active wells located on the applicable portion of the Assets
                  operated by Seller after the Closing Date, Purchaser shall pay
                  Seller the Council of Petroleum Accountants Society overhead
                  charge for each active well per month. Any such charges and
                  expenses shall be recovered by Seller as part of the Final
                  Settlement Statement .

         (b)      From the date hereof  until the Closing  Date,  Seller shall 
                  (or, with respect to non-operated wells, shall use reasonable
                  commercial efforts to cause the operator of such wells to):
                  (i) not abandon any well on any lease listed on EXHIBIT A
                  hereto (the "Leases") capable of commercial production, or
                  release any such Lease; (ii) not develop, maintain or operate
                  the Assets in a manner materially inconsistent with prior
                  operations; (iii) not commence any operation on any Leasehold
                  Property anticipated to cost in excess of $25,000 per
                  operation net to Seller's interest (except emergency
                  operations and operations required under presently existing
                  contractual obligations and the on-going commitments under the
                  authorization for expenditures ("AFEs") described on SCHEDULE
                  6.17 attached hereto); (iv) not create or suffer to exist any
                  lien, security interest or other encumbrance with respect to
                  any Asset (except for Permitted Encumbrances); (v) not enter
                  into any agreement for the sale, disposition or encumbrance of
                  any Asset; (vi) not dedicate, sell, encumber or dispose of any
                  oil and gas production attributable to the Assets except in
                  the ordinary course of business; (vii) not agree to any
                  material alterations in the Leases or other contractual
                  agreements governing any Leasehold Property and not enter into
                  any new contracts relating to the Assets (except for contracts
                  terminable without penalty by Seller on not more than 30 days
                  notice); (viii) maintain in force all insurance policies
                  covering the Assets that are presently in force; (ix) maintain
                  the Leases in full force and effect and comply with all
                  express covenants contained therein; (x) pay or cause to be
                  paid all costs and expenses incurred in connection with the
                  Assets before they become delinquent (unless same is not
                  material in amount and is being contested in good faith); (xi)
                  maintain in all material respects the Assets in a manner
                  consistent with prior operations; (xii) exercise due diligence
                  in safeguarding and maintaining secure and confidential all
                  geological and geophysical maps, confidential reports and data
                  and all other confidential data included

                                      -18-

                  in the Assets or relating in any way to the Leasehold
                  Property, provided, however, Purchaser is aware that Seller
                  has provided prospective purchasers of the Assets with
                  confidential data and Purchaser agrees that the retention of
                  such data by the recipients thereof shall not cause Seller to
                  be in breach of this covenant; (xiii) furnish Purchaser with
                  copies of all AFEs on material operations commenced, but not
                  completed, prior to the Effective Date; (xiv) not voluntarily
                  relinquish its position as operator with respect to any of the
                  Leasehold Properties; and (xv) not allow any emission,
                  discharge, or release into the environment of any pollutant,
                  contaminant or Hazardous Substance from or attributable to any
                  Asset.

         (c)      From and after the date of this  Agreement  until  Closing,  
                  Seller shall: (i) identify and use reasonable commercial
                  efforts to obtain any and all necessary consents, waivers
                  (including waivers of preferential purchase rights),
                  permissions and approvals of third parties or governmental
                  authorities in connection with the sale and transfer of the
                  Assets to Purchaser; (ii) afford Purchaser the right to
                  approve in advance all letters and other documents sent to any
                  third party concerning consents and preferential rights of
                  such third party to purchase any portion of the Assets or
                  prohibit the sale thereof to Purchaser; (iii) file or cause to
                  be filed all reports required to be filed with governmental
                  authorities relating to the Assets; (iv) consult with
                  Purchaser from time to time, upon Purchaser's request,
                  concerning the operation and development of the Assets and
                  Seller's compliance with its covenants and agreements
                  hereunder; (v) maintain its organizational status as a
                  corporation and assure that as of the Closing Date it will not
                  be under any legal or contractual restriction that would
                  prohibit or delay the Closing; (vi) obtain or cause to be
                  obtained all permits, licenses and other authorizations
                  required under applicable federal, state and local laws,
                  including Environmental Laws; (vii) remain and cause the
                  Assets to remain in compliance in all material respects with
                  all Environmental Laws and all terms and conditions of such
                  permits, licenses and authorizations; and (viii) immediately
                  inform Purchaser upon receipt of notice, or otherwise upon
                  becoming aware, of any past, present or future events,
                  conditions, activities, incidents or plans that are reasonably
                  likely to interfere with continued compliance, or that are
                  reasonably likely to give rise to any liability, claim,
                  investigation or proceeding based on or related to the
                  processing, distribution, use, treatment, storage, disposal,
                  transport, or handling, or the emission, discharge, release or

                  contaminant, or Hazardous Substance from or attributable to
                  any of the Assets.

                                      -19-

         5.2      CASUALTY LOSS:

         (a)      The risk of casualty loss relating to the Assets shall pass
                  from Seller to Purchaser as of the Closing Date, and Purchaser
                  shall assume all risk of any change in condition of the Assets
                  from and after the Closing Date.

         (b)      If, prior to the Closing, any of the Leasehold Property is
                  destroyed by fire, casing collapse, blowout or other casualty,
                  Purchaser may elect to treat each Leasehold Property affected
                  by such casualty as if it suffered from a Title Defect.

         5.3      [Intentionally omitted.]

         5.4      SUCCESSOR OPERATOR: While Purchaser may represent that it 
     desires to succeed Seller as operator of the Assets or portions thereof
     which Seller may presently operate, Purchaser acknowledges and agrees that
     Seller cannot and does not covenant or warrant that Purchaser shall become
     successor operator of same since the Assets or portions thereof may be
     subject to unit, pooling, communitization or operating agreements or other
     agreements or applicable laws and/or regulations which control the
     appointment of a successor operator. Seller agrees, however, that as to the
     Assets it operates, where it can facilitate the appointment of a successor
     operator, Seller will, in a prudent manner at or immediately prior to
     Closing, resign as operator.

         5.5      NOTICE OF CERTAIN EVENTS: It being the intention of Seller and
     Purchaser that Seller shall engage in a continuous disclosure process from
     the date hereof through the Closing Date, Seller shall promptly notify
     Purchaser if Seller learns at any time on or before the Closing Date of the
     occurrence or non-occurrence, as applicable, of: (i) any dispute or
     proceeding between Seller, or any third party operator of any Leasehold
     Property, with a governmental agency or any other person or entity that, if
     adversely determined, could have a material adverse effect on the ownership
     or operation of the Assets; (ii) any material default or noncompliance of
     any party to any of the Leases or other agreements, orders and other
     instruments related to the Leasehold Property with any of the terms and
     conditions thereof, or any notice of termination or other material
     proceedings or actions that might reasonably be expected to materially and
     adversely affect any of the Leases or Leasehold Property, together with a
     detailed statement of the steps being taken to cure such default,
     noncompliance or termination; (iii) any amendment (unless such amendment is
     not material or is permitted by this Agreement or by any consent of
     Purchaser to a deviation from the terms of this Agreement) of any of the
     Leases or other agreements, orders and other instruments related to
     theLeasehold Property, together with a copy of such amendment; (iv) the
     intended sale, encumbrance or other disposition of any Asset; (v) the
     emission, discharge, 

                                      -20-

     release or threatened release into the environment of any pollutant,
     contaminant or Hazardous Substance from or attributable to any of the
     Assets; or (vi) any other event or condition that would make any
     representation or warranty (including the information set forth in the
     Schedules attached hereto) made by Seller to Purchaser not true and correct
     in all material respects, or any agreement or covenant required to be
     performed herein unable to be performed as provided herein.

         5.6      [Intentionally omitted.]

     general equitable principles. Each of Purchaser and Seller represents as to
     itself that all instruments required hereunder to be executed and delivered
     by each of Purchaser and Seller at the Closing will, when executed and

                  its certificate of incorporation or by-laws or, in any
                  material respect, any other agreements or instruments to which

                  effect on Purchaser or its ownership or operation of the
                  Assets on and after the Closing Date.

     agreement to which Purchaser or Seller is a party. Seller represents that
     neither the execution and delivery of this Agreement nor the consummation
     of the transactions contemplated hereby result or will result in any

                  Purchaser's rights under Sections 4.6, 9.2 and 12.18, be
                  solely liable and responsible for the proper plugging and

                  therewith, and shall indemnify, defend and hold harmless
                  Seller and its agents from and against all claims relating to
                  same.

         (b)      Except with respect to Claims for which Purchaser has agreed
                  to indemnify and hold harmless Seller pursuant to Section

                  defend and hold harmless Purchaser and its Agents from and

                  obligations arising under or by virtue of any lease, contract,
                  agreement, permit, applicable statute.

         (c)      Any claim for indemnity  under any provision of this 
                  Agreement, including Sections 4.6 and 9.2, shall be made by
                  written notice from the party seeking indemnification (the
                  "Indemnified Party") to the party required to provide such
                  indemnification (the "Indemnified Party"), together with a
                  written description of any third party claim against the
                  Indemnified Party. The Indemnifying Party shall have a period
                  of thirty (30) days after receipt of such notice within which
                  to respond thereto or, in the case of a third party claim
                  which requires a shorter time for response, then within such
                  shorter period as specified by the Indemnified Party in such
                  notice (the "Notice Period"). If the Indemnifying Party denies
                  liability or fails to respond to the notice within the Notice
                  Period, the Indemnified Party may defend or compromise the
                  claim as it deems appropriate without prejudice to any of the
                  Indemnified Party's rights hereunder, with no further
                  obligation to inform the Indemnifying Party of the status of
                  the claim and no right of the Indemnifying Party to approve or
                  disapprove any action, taken in 

                                      -32-

                  connection therewith by the Indemnified Party. If the
                  Indemnifying Party accepts the obligation to respond, it shall
                  so notify the Indemnified Party within the Notice Period and
                  elect either: (i) to undertake the defense or compromise of
                  such third party claim with counsel selected by the
                  Indemnifying Party and reasonably approved by the Indemnified
                  Party or (ii) to instruct the Indemnified Party to defend or
                  compromise such claim. If the Indemnifying Party undertakes
                  the defense or compromise of such third party claim, the
                  Indemnified Party shall be entitled, at its own expense, to
                  participate in such defense. No compromise or settlement of
                  any third party claim shall be made without reasonable notice
                  to the Indemnified Party and, unless such compromise or
                  settlement includes a general release of the Indemnified Party
                  in respect of the matter with no admission of liability on the
                  part of the Indemnified Party and no constraints on the future
                  conduct of its business, without the prior written approval of
                  the Indemnified Party.

         9.3      FURTHER ASSURANCES: After Closing, Seller and Purchaser agree 
     to take such further actions and to execute, acknowledge and deliver all
     such further documents that are reasonably necessary to carry out the
     purposes of this Agreement or of any document delivered pursuant hereto.

         9.4      RECORDING: Purchaser shall, at its own cost, immediately 
     record the Assignments in the appropriate offices of the counties and
     parishes adjacent to that portion of the subsoil and seabed of the Outer
     Continental Shelf being the subject of the Assignments that would fall
     within such county's or parish's boundaries if extended seaward. Purchaser
     shall immediately file for all requisite approvals of any federal
     governmental agencies to the Assignments. The Assignments shall be filed in
     the appropriate governmental offices on a form required and in compliance
     with the applicable rules of such governmental agencies. Purchaser shall
     supply Seller with a true and accurate photocopy of the recorded and filed
     Assignments, together with evidence of approval of the Assignments by
     applicable governmental authorities, within a reasonable period of time
     after their recording and filing.

         9.5      FURTHER ASSURANCES REGARDING WEST CAMERON 254

          (a)     Seller shall use its reasonable commercial efforts to cause an
                  assignment from Vastar Resources Inc. in favor of Walter Oil &
                  Gas Corporation ("Walter") of 100% record title interest in
                  OCS-G 7608 to be properly executed and approved by the
                  Minerals Management Service (the "MMS").

                                      -33-

          (b)     Before Closing, Seller shall use its reasonable commercial
                  efforts to obtain and file for approval with the MMS a
                  properly executed assignment from Walter in favor of Seller of
                  22.75% record title interest in OCS-G 7608, and shall take all
                  action reasonably necessary to cause such assignment to be
                  approved by the MMS, including, without limitation, the
                  posting of any bonds or securities in such amount as may be
                  required by the MMS as a condition to the issuance of such
                  approval.

         9.6      ACCOUNTING FOR PROCEEDS FROM THE SALE OF PRODUCTION. If after 
     the Closing Seller receives any proceeds from the sale of production that
     are attributable to production from the Leasehold Property after the
     Effective Date, or attributable to the merchantable oil or condensate in
     the tanks on the Effective Date, Seller shall remit such proceeds to
     Purchaser within fifteen (15) days after receipt of such proceeds by
     Seller. In the event that after the Closing Purchaser receives any proceeds
     from the sale of production that are attributable to production from the
     Assets prior to the Effective Date, except for proceeds attributable to the
     merchantable oil or condensate in the tanks on the Effective Date,
     Purchaser shall remit such proceeds to Seller within fifteen (15) days
     after receipt of such proceeds by Purchaser.

     independent investigation of the Assets and upon the representations and
     covenants in this Agreement. EXCEPT AS SPECIFICALLY PROVIDED IN THIS
