7.       APPOINTMENT OF OPERATOR

         Unigeo, subject to clause 16, is hereby appointed the initial Operator
         to conduct operations on the Rostin Block. GEOCAN, however, will be
         responsible for the supervision of all drilling, completion, equipping,
         and abandonment operations conducted on the Rostin Block.

8.       APPLICATION OF OPERATING PROCEDURE

         The Operating Procedure will apply to all operations conducted in
         respect of the maintenance, exploration and development of the Rostin
         Block for the production of petroleum substances pursuant to the Title
         Documents and the applicable regulations.

9.       STUDY PHASE

         Subject to clause 16, on or before October 31, 2000, GEOCAN will review
         and finalize with the Parties a detailed budget that outlines the work
         program and associated costs for the Study Phase on the Rostin Block.
         During the Study Phase Unigeo and GEOCAN will review all of the
         geological and geophysical data that is available including geological
         and geophysical information held by COC, over the Rostin Block, in
         order to assess the potential for drilling a Test Well, as described in
         clause 11. The costs incurred during the Study Phase will be shared in
         the participating interests described in clause 5.

         At the end of the Study Phase Unigeo and GEOCAN will elect to proceed
         to the Seismic Phase, as described in clause 10, elect to drill a Test
         Well or discontinue to do any further work on the Rostin Block.

10.      SEISMIC PHASE

         If during the Study Phase Unigeo and GEOCAN are not able to determine
         that a Test Well should be drilled and Unigeo and GEOCAN elect to
         proceed to the Seismic Phase, GEOCAN subject to clause 16, will prepare
         for approval by the Parties hereto a budget for the shooting of a
         seismic program on the Rostin Block, that will include the timing for
         shooting seismic, the size of the seismic program and the costs
         associated to shooting, processing, and interpreting the data. The
         costs incurred during the Seismic Phase will be shared in the
         participating interests described in clause 5. If only one Party elects
         to shoot the seismic program it will do so at its sole cost risk,
         expense and own the seismic data and trading rights 100%. The Party
         that elects not to participate will not receive a copy of the data or
         share in the interpretation of said data.

         At the end of the Seismic Phase Unigeo and GEOCAN will elect to drill a
         Test Well or discontinue to do any further work on the Rostin Block.

11.      TEST WELL

         a)   If Unigeo and GEOCAN elect to drill a Test Well they will spud the
              Test Well at a location of their choice on the Rostin Block and
              will then diligently and

              continuously, at their sole cost, risk and expense drill a well,
              log, test, and Complete or Abandon the same in accordance with the
              terms and conditions of this Agreement and the Czech Republic
              regulations.

         b)   If the Test Well is found to be capable of production in Paying
              Quantities, Unigeo and GEOCAN will Equip such well for production
              by paying all Completion costs and Equipping costs. If, however,
              the Test Well is capable of production, which is primarily natural
              gas, and there is not an adequate market immediately available
              therefor, Unigeo and GEOCAN may Cap such well until an economic
              market for the gas becomes available, at which time Unigeo and
              GEOCAN will Complete and Equip the Test Well at its sole cost,
              risk and expense.

         c)   If the Test Well is not capable of production in Paying
              Quantities, Unigeo and GEOCAN will, subject to the Abandonment
              Clause, Abandon the Test Well at is sole cost, risk and expense,
              in a manner satisfactory to the Minister of Environment, and will
              clean up the wellsite and access road.

         d)   Unigeo and GEOCAN will share the costs of the Test Well as to
              their participating interests described in clause 5.

12.      ABANDONMENT

         If, at anytime after drilling the Test Well, but prior to completing
         the Test Well, Unigeo and GEOCAN wish to Abandon the Test Well, the
         Parties will comply with the following provisions:

         a)   Unigeo and GEOCAN will give COC written notice that it wishes to
              Abandon the Test Well. Provided COC is in receipt of all related
              log, and test data, COC must respond to Unigeo and GEOCAN
              abandonment notice within forty-eight (48) hours of receipt of the
              notice in the case where there is a drilling rig on location, or
              in all other cases, within thirty (30) days.

         b)   If COC fails to respond or COC advises Unigeo and GEOCAN by
              written notice that COC consents to the Abandonment of the Test
              Well, Unigeo and GEOCAN will, at their sole cost, risk and
              expense, Abandon the Test Well in accordance with good oilfield
              practice and the Czech Republic regulations.

         c)   If COC advises Unigeo and GEOCAN that it does not consent to the
              Abandonment of the Test Well, Unigeo and GEOCAN will, for the
              purposes of this Agreement, be deemed to have Completed or
              Abandoned the Test Well. COC will take over the Test Well and
              conduct all further operations relating thereto at its sole cost,
              risk and expense. The estimated costs of Abandonment and the
              estimated net salvageable value of material and equipment will be
              calculated. In the event the estimated Abandonment costs exceed
              the estimated net salvageable value, the difference will be paid
              by Unigeo and GEOCAN to COC. In the event the estimated net
              salvageable value exceeds the estimated Abandonment costs, the
              difference will be paid by COC to Unigeo and

              GEOCAN. COC will then receive from Unigeo and GEOCAN a surrender
              in a form satisfactory to COC of all Unigeo and GEOCAN'S interest
              in and to the Test Well, and all material and equipment in and on
              the surface rights, and all other contracts relating to the Test
              Well and necessary for COC'S further operations. If COC Completes
              the Test Well, Unigeo and GEOCAN will also surrender to COC their
              interest in the Test Well spacing unit insofar as it relates to
              the Completed formation(s). Unigeo and GEOCAN will save COC
              harmless from all costs, debts, claims, charges and damages
              relating to the documents so assigned up to the time of take over
              of the Test Well.

         d)   COC will be liable to Unigeo and GEOCAN for all loss, costs,
              damages and expenses whatsoever which it may suffer, sustain, pay
              or incur and in addition will indemnify and save harmless Unigeo
              and GEOCAN against all actions, suits, costs, and demands which
              may be brought against or suffered by Unigeo and GEOCAN arising
              out or in any way attributable to the operations carried on by COC
              on the Test Well and the Test Well Spacing Unit after take over
              pursuant to this Clause.

13.      GROSS OVERRIDING ROYALTY

         Upon Unigeo and GEOCAN drilling the Test Well pursuant to this
         Agreement, the Royalty Agreement will be deemed to have been executed
         and delivered with respect to the Test Well spacing unit. COC will
         receive a gross overriding royalty, as described in the Royalty
         Agreement, subject to the right of conversion of the gross overriding
         royalty described in clause 14.

14.      CONVERSION OF GROSS OVERRIDING ROYALTY

         a)   Unigeo and GEOCAN will, in addition to the other required Test
              Well information, furnish to COC every three (3) months following
              Completion of the Test Well an accurate and itemized record of all
              production secured from the Test Well and any other information
              with respect to the operation of and production from the Test Well
              as may be requested by COC.

         b)   Upon Payout, Unigeo and GEOCAN will send written notice of Payout
              to COC. COC will have a period of thirty (30) days from receipt of
              such notice to elect to convert its gross overriding royalty
              interest to a 15% working interest in the Test Well spacing unit.
              Failure to make an election will be deemed an election not to
              convert. If COC elects to convert its gross overriding royalty
              interest to a working interest, then after the effective date of
              election as provided in sub clause (c) COC will own said working
              interest in the Test Well spacing unit, the Test Well, all
              equipment therein and thereon and all production therefrom. The
              provisions of Schedule "B" will then apply to govern the
              relationship of Unigeo and GEOCAN and COC with respect to all
              operations on the Test Well spacing unit.

16.      OPERATING COMMITTEE

         a)   To provide for the orderly supervision and direction of all
              operations under this Agreement, there shall be an Operating
              Committee set up which is comprised of representatives of each
              Party to this Agreement; each Party is to appoint one
              representative and one alternate to serve thereon. Operator's
              representative shall be chairman of the Operating Committee. The
              alternate appointed by a Party shall only act in the event the
              representative appointed by such Party is not available. Each
              Party shall have the right to change its representative and
              alternate at any time by notifying the other Parties to that
              effect. Each Party shall be entitled to vote through its
              representative or alternate in proportion to its participating
              interest from time to time. Other personnel including consultants
              (to a maximum of two) of a Party may attend Operating Committee
              meetings as observers. Except as otherwise provided elsewhere in
              this Agreement and subject to Article X of the Operating
              Procedure, the decisions of the Operating Committee on all matters
              coming before it shall be made by a vote of a total participating
              interest, as provided for in Clauses 5 and 15, of at least eighty
              - five percent (85.0%).

         b)   In matters relating to operations pursuant to Article X of the
              Operating Procedure only participating Parties shall be entitled
              to vote.

         c)   The Operating Committee shall meet whenever requested by the
              giving of at least thirty (30) days prior written notice by
              Operator (who shall give such notice when requested by any Party)
              and shall meet at least once in each six months commencing with
              January 1, or July 1, of each calendar year (calendar semester),
              to consider a work program and budget. At the time of providing
              notice, Operator

              shall also supply a reasonably detailed agenda for the meeting and
              a matter not appearing on said agenda may not be proposed for a
              vote at the meeting unless all the Parties otherwise agree or
              unless any Party wishing to propose a matter for a vote notifies
              all other Parties in writing at least five (5) days prior to the
              date of such meeting of a matter or matters it intends to propose
              for a vote at the meeting. However, by the unanimous agreement of
              all Parties any such calendar semester meeting may be cancelled in
              the event it is unnecessary. Except as herein otherwise provided,
              the decisions of the Operating Committee shall be binding on all
              Parties. Meetings of the Operating Committee shall be held in
              Ostrava-Hrabova, Czech Republic at the offices of Operator or at
              such place as the Parties may unanimously agree. Parties not in
              attendance at a meeting of the Operating Committee may, if
              entitled to vote at that meeting, nonetheless cast a written vote
              or vote by proxy concerning any matter referred for such meeting,
              provided that written notice of such vote or proxy is received by
              the Operator prior to the vote taken by the Operating Committee on
              such matter at the meeting. At the commencement of the meeting,
              Operator shall supply to all the Parties present, for their
              approval, a written summary record of all proposals formally
              tabled for vote. This record shall include the identity of the
              proposing Party or Parties. Minutes of each meeting shall be
              prepared by Operator and copies thereof shall be provided promptly
              to the Parties. Such minutes shall be deemed approved thirty (30)
              days after receipt by all Parties unless prior thereto a Party has
              given notice of objection.

         d)   Subject to the terms of this Agreement the Operating Committee
              shall have the sole and exclusive right to exercise overall
              supervision of and to determine, and control the maintenance,
              exploration operations and development of the Rostin Block and the
              production, storage and transport of Petroleum Substances produced
              and saved therefrom.

         e)   Not withstanding anything to the contrary in this clause, each of
              the Parties shall be entitled to have direct representation on the
              Operating Committee and be entitled to vote in proportion to its
              participating interest, as provided for in clauses 5 and 15, at
              the time of voting on any proposal or matters which may be
              submitted to the Operating Committee in accordance with this
              Agreement if and for so long as such Party holds a participating
              interest of not less than ten percent (10%). Any Party whose
              participating interest is less than ten percent (10%) shall not be
              entitled to direct representation on the Operating Committee,
              provided, however, any two or more Parties holding a participating
              interest of ten (10%) or more in the aggregate may designate a
              representative to serve on the Operating Committee and represent
              them jointly and vote uniformly in respect of their combined
              participating interests. No Party holding a participating interest
              of less than ten percent (10%) shall contact the Operator or the
              Operating Committee except through its designated representative.
