  respective counsel and accountants, all information and documents
  reasonably available to them which relate to any action, suit or
  proceeding, and the Parties agree to render to each other such assistance

     7.4Good and Marketable Title. As used herein the term "good and
  marketable title" shall mean:

          (A) As to each of the Wells, that record title of Seller which:

              (i) entitles Seller to receive from each Well not less than the
                  interests shown in Exhibit A as the "Net Revenue Interest"
                  of all Oil and Gas produced, saved and marketed from each
                  Well and of all Oil and Gas produced, saved and marketed
                  from any unit of which each Well is a part and allocated to
                  such Well, all without reduction, suspension or termination
                  of the interests in each Well throughout the duration of the
                  Lease upon which such Well is located, except as stated in
                  such Exhibit; and

              (ii) obligates Seller to bear a percentage of the costs and
                   expenses relating to the maintenance and development of,
                   and operations relating to, the Wells not greater than the
                   "Working Interest" shown in Exhibit A, all without increase
                   of the interests in each Well throughout the duration of
                   such Well, except as stated in such Exhibit.

          (B) That title of Seller to the Assets which:

              (i) at or prior to Closing, is free and clear (except for
                  Permitted Encumbrances as defined in subsection (ii) below)
                  of liens and encumbrances and (a) with respect to real
                  property interests to be transferred to Buyer, real property
                  interests are of record in the relevant counties and
                  governmental offices; and (b) with respect to any Asset
                  subject to preferential rights, such rights have been waived
                  and consents obtained from all third parties, and

              (ii) "Permitted Encumbrances" shall mean (i) lessor's royalties,
                   overriding royalties, reversionary interests and other
                   burdens on production that, in the aggregate, do not
                   operate to reduce the Net Revenue Interest of Seller in
                   each of the Wells to an amount less than that shown on
                   Exhibit A; (ii) division orders, and sales contracts
                   covering hydrocarbons and associated products that are
                   terminable upon no more than thirty (30) days notice; (iii)
                   preferential purchase rights and required third party
                   consents to assignments and similar rights with respect to
                   which waivers or consents are obtained from the appropriate
                   parties or the appropriate time period for asserting such
                   rights has expired without an exercise thereof; (iv)

                   pipelines, grazing, logging, canals, ditches, reservoirs,
                   or the like; use conditions, covenants or other
                   restrictions in the chain of title; (v) minor
                   irregularities in title which do not (a) materially
                   interfere with the occupation, use and enjoyment by Seller
                   of any of the Assets in the normal course of business as
                   presently conducted; or (b) materially impair the value
                   thereof for such Assets; (vi) all interests in the Assets
                   securing obligations owed to, or claimed by, any person
                   whether such interest is based on the common law, statute
                   or contract, and whether such interest includes liens or
                   security interests arising by virtue of mortgage,
                   encumbrance, pledge, security agreement, conditional sale
                   or trust receipt or lease, consignment or bailment for

                                       7


                 security purposes, so long as each said interest has been
                 expressly consented to by Buyer in writing or will be
                 released in full at or prior to the Closing; and (vii)
                 specific exceptions and encumbrances affecting each of the
                 Assets as described in Exhibit A INSOFAR ONLY as said
                 exceptions and encumbrances are valid and subsisting and are
                 enforceable against the particular Asset which is made
                 subject to said exceptions and encumbrances.

     7.5Defect Letters.

           (A) Buyer may from time to time prior to the date which is five (5)
               days prior to the Closing Date notify Seller in writing (a

               obligations, encumbrances, defects and irregularities of title
               which would cause title to all or part of the Assets not to be
               good and marketable as defined in Section 7.4 hereof, or which
               would cause a breach of a representation or warranty of Seller
               ("Title Defect").

           (B) A Title Defect as set forth in a Notice, which is given to
               Seller on or before the date which is five (5) days prior to
               the Closing Date and is not cured on or before the Closing,
               unless the time for cure is extended in writing by Buyer, shall
               be a "Title Failure," unless waived by Buyer. Any Title Defect
               waived by Buyer under this Section or any Title Defect for
               which timely notice shall not have been given in accordance
               with Section 7.5 (A) shall become a Permitted Encumbrance as
               defined in Section 7.4(B)(ii) and Buyer shall have no claim or
               other right against Seller with respect thereto.

     7.6Effect of Title Failure. In the event of a Title Failure pursuant to
  Section 7.5, the Buyer shall have the right not to accept the Asset(s) or
  portion thereof to which such Title Failure relates and to an adjustment of
  the Purchase Price in the amount of the Allocated Value(s) or portion
  thereof attributable to such Title Failure. Buyer shall not be liable for
  any portion of the cost of any title curative performed by Seller.

               challenging, or seeking revocation or limitation of any such
               permits, licenses, approvals and consents. All plans,
               applications, reports, certificates and other instruments filed

14.TERMINATION.

     14.1Causes of Termination. This Agreement and the transactions
  contemplated herein shall be completely terminated:

           (A) At any time by mutual consent of the Parties;

           (B) By either Party if the Closing shall not have occurred by
               September 1, 1999, despite the good faith reasonable efforts of
               the Parties, and if the Party desiring to terminate is not in
               breach of this Agreement;

           (C) By either Party at its election in the event of a Casualty Loss
               pursuant to Section 15.1(B);

           (D) By either Party if more than ten percent (10%) of the Allocated
               Value of the Assets is subject to a Title Failure;

     14.2Effect of Termination. In the event of the termination of this
  Agreement pursuant to the provisions of this Article 14 or elsewhere in
  this Agreement, this Agreement shall become void and have no further force
  and effect and neither Party shall have any further right, duty or
  liability to the other hereunder. Upon termination as provided in this
  section, each Party agrees, upon request, to use its best efforts to return
  to the other or destroy, all materials, documents and copies thereof
  provided, obtained or discovered in the course of any due diligence
  investigations.

15.MISCELLANEOUS.

     15.1Casualty Loss.

           (A) As used herein the term "Casualty" means an adverse change in
               the Assets taken as a whole caused by an event of casualty,
               including but not limited to, volcanic eruptions, acts of God,
               fire, explosion, earthquake, wind storm, strike, lockout, labor
               dispute, flood, drought, war, embargo, riot, condemnation, the
               exercise of any right of eminent domain, confiscation, seizure,
               activities of armed forces, blowout, casing collapse or other
               event causing a Well failure, operation of laws, rules or
               regulations (regardless of whether covered by insurance), but
               excepting depletion due to normal production, depreciation of
               equipment through ordinary wear and tear and transactions
               permitted under this Agreement).

           (B) If, prior to the Closing, a Casualty occurs (or Casualties
               occur) which results in a reduction in the value of the Assets
               ("Casualty Loss") in excess of ten percent (10%) of the
               Purchase Price, either Party may elect to terminate this
               Agreement. If this Agreement is not so terminated, then this
               Agreement shall remain in full force and effect notwithstanding
               any such Casualty Loss, and, at the sole option of the Buyer,
               (i) Seller may retain such Asset and such Asset shall be
               subject to the adjustment of Purchase Price in the same manner
               set forth in Section 7.6 hereof, or (ii) at the Closing Seller
               shall pay to Buyer all sums paid to Seller by reason of such
               Casualty Loss, provided however, that the Purchase Price shall
               not be adjusted by reason of such payment, and Seller shall
               assign, transfer and set over unto Buyer all of the right,
               title and interest of Seller in and to such Asset and any
               unpaid awards or other payments arising out of such Casualty
               Loss. Seller shall not voluntarily compromise, settle or adjust
               any amounts payable by reason of such Casualty Loss without
               first obtaining the written consent of Buyer.

           (C) For purposes of determining the value of a Casualty Loss, the
               Parties shall use the same methodology as applied in
               determining the value of a Title Failure as set forth in
               Section 7.6.

                                       13


     15.2Non-Compete.

           (A) The Parties agree that the area outlined on Exhibit F is
               designated as a Non-Compete Area. For a period terminating on
               the earlier of (i) two (2) years after Closing or (ii) the date
               on which Buyer shall have conveyed to non-affiliated third
               parties a substantial portion of the Assets, Seller agrees that
               it will, either directly or indirectly, acquire any oil and gas
               leases or oil and gas rights covering lands within the Non-
               Compete Area;

           (B) If Seller should acquire, either directly or indirectly, any
               interest in any property or lease rights, either wholly or
               partially within the Non-Compete Area, within the time period
               referenced in Section 13.2 (A) Buyer shall have the right, but
               not the obligation, to acquire from Seller, all of the interest
               acquired by Seller. After receipt of written notice from Seller
               of its acquisition, Buyer shall have thirty (30) days after
               receipt of such notice to exercise its right to acquire such
               interest from Seller by paying to Seller Seller's cost of such
               acquisition; and

           (C) This Non-Compete provision shall terminate and have no further
               force or effect if Seller is merged or enters into a corporate
               reorganization with an unrelated company or entity that already
               owns oil and gas leases within the Non-Compete Area, or if
               Seller makes an acquisition of oil and gas assets that
               includes, in part, oil and gas leases within the Non-Compete
               Area; provided that, in either case, the oil and gas leases
               within the Non-Compete Area shall comprise no more than 25% of
               the assets of the unrelated company or the oil and gas asset
               acquisition, as applicable.

     15.3Notice. Any notice, request, demand, or consent required or
  permitted to be given hereunder shall be in writing and delivered in person
