6.1      GENERAL INDEMNITY

         Purchaser shall:

         (a)      be liable to Vendor for all Losses, (including legal costs on
                  a solicitor/client basis) whatsoever which Vendor may suffer,
                  sustain, pay or incur; and, in addition

         (b)      indemnify and save Vendor and its directors, officers,
                  servants, agents and employees harmless from and against all
                  Losses (including legal costs on a solicitor/client basis)
                  whatsoever which may be brought against or suffered by Vendor
                  or its directors, officers, servants, agents or employees or
                  which it may suffer, sustain, pay or incur;

         by reason of any matter or thing arising out of, resulting from,
         attributable to or connected with the Assets and occurring or accruing
         on or after the Effective Date, except any Losses to the extent that

         misconduct of Vendor or are caused by a breech of the Vendor's
         representations and warranties contained in Section 4.1. The
         responsibility prescribed by this clause, however, does not provide an
         extension of any representation or warranty under Section 4.1 or any
         additional remedy for the Purchaser's breech thereof..

6.2      ABANDONMENT AND RECLAMATION

         clause 4.1 hereof, Purchaser shall see to the timely performance of all

         in the absence of this Agreement would be the responsibility of Vendor.
         Purchaser shall be liable to Vendor and shall, in addition, indemnify
         Vendor from and against all Losses suffered, sustained, paid or
         incurred by Vendor should Purchaser fail to timely perform such
         obligations, subject to Vendor's representations and warranties in

         Notwithstanding the foregoing provisions of this clause, but subject to
         the representations and warranties of Vendor contained in clause 4.1
         (q), it is understood and agreed that Purchaser is acquiring the Assets
         on an "as is, where is" basis as of the Effective Date. Purchaser
         agrees that it is familiar with the condition and use of the Assets and
         the wells located on the Lands (or lands with which the Lands have been

<PAGE>   22

         Vendor has provided Purchaser with a reasonable opportunity to inspect
         the Assets and the Lands (or lands with which the Lands have been
         pooled or unitized) at the sole cost, risk and expense of Purchaser
         (insofar as Vendor could reasonably provide such access) and that it is
         not relying upon any representation or warranty from Vendor as to the
         condition, environmental or otherwise, of the Assets except as is
         specifically made pursuant to clause 4.1 (q). Purchaser further agrees
         that on and after the Effective Date it shall:

         (i)      be solely liable and responsible for any and all Losses
                  (including legal costs on a solicitor/client basis) whatsoever
                  which Vendor may suffer, sustain, pay or incur; and, in
                  addition

         (ii)     indemnify and save Vendor and its directors, officers,
                  servants, agents and employees harmless from and against any
                  and all Losses (including legal costs on a solicitor/client
                  basis) whatsoever which may be brought against or suffered by
                  Vendor or its directors, officers, servants, agents or
                  employees or which it may suffer, sustain, pay or incur;

         by reason of any matter or thing arising out of, resulting from,
         attributable to or connected with any environmental damage or
         contamination or other environmental problems pertaining to the Assets
         or to any well located on the Lands, or any of them, whether occurring
         or accruing before, on or after the Effective Date including, without
         limitation, surface, underground, air, ground water or surface water
         contamination, damage from or removal of hazardous or toxic substances,
         spills of any nature whatsoever, clean-up, plugging, well abandonment
         and reclamation or failure to perform any or all of the foregoing and
         the breach of applicable Regulations in effect at any time. Purchaser
         hereby releases Vendor from any claims Purchaser may have against
         Vendor and, in addition, Purchaser hereby waives any rights it may have
         to name Vendor as a third party to any action commenced against
         Purchaser with respect to all such liabilities and responsibilities,
         except for any claims which Purchaser may have for the breach of a
         representation or warranty made by Vendor pursuant to clause 4.1.

6.4      APPLICATION TO OTHER DOCUMENTATION

         The liabilities and indemnities contained in Article 6 shall be deemed
         to apply to, and shall not merge in, any conveyances, transfers,
         assignments, novation agreements and other documents or instruments
         conveying the Assets to Purchaser or otherwise provided with respect to
         the transactions herein, despite the actual terms of such agreements,
         notwithstanding any rule of law, equity or statute to the contrary, and
         all such rules are hereby waived. Any claim by a Party must be made by
         notice to the other Party and include particulars of the claim and of
         the facts giving rise to it.

                                                                              21

         Vendor's gross negligence or its wilful misconduct.

                                                                              25

         consent of Purchaser, which consent shall not be unreasonably withheld
         by Purchaser and which, if provided, shall be provided in a timely
         manner:

         (a)      make any commitment or propose, initiate or authorize any
                  capital expenditure with respect to the Assets of which
                  Vendor's share is in excess of $10,000.00, except in case of
                  an emergency or in respect of amounts which Vendor may be

                  without its consent;

         (b)      surrender or abandon any of the Assets;

         Notwithstanding the foregoing, Vendor may assume such obligations or
         commitments and propose or initiate such operations or the exercise of
         any such right or option without the prior consent of Purchaser, if
         Vendor reasonably determines that such expenditures or actions are
         necessary for the protection of life, property, or income, in which
         case Vendor shall promptly notify Purchaser of such intentions or
         actions and Vendor's estimate of the costs and expenses associated
         therewith.

                                                                              26

                    TITLE DEFECTS AND RIGHTS OF FIRST REFUSAL

10.1     NOTICE OF MATERIAL TITLE DEFECTS

         From time to time, as soon as reasonably practicable after
         determination, and in any event no later than 7 Business Days before

         Title Defects. Such notice shall include a description of each Material
         Title Defect and the interests affected thereby, the value allocated by

         affected interest has been reduced by the Material Title Defect.
         Failure to include a Material Title Defect in a written notice shall be
         deemed to be a waiver of such Material Title Defect for the purposes of
         this section.

10.2     RECTIFICATION BY VENDOR

         Prior to the Closing Date, Vendor shall use all reasonable efforts to
         cure or rectify the Material Title Defects which Purchaser gives notice

         cured or removed at or prior to the Closing Date:

         (a)      where the cumulative amount by which the value of the affected
                  interests has been reduced is, less than 5% of the Purchase
                  Price (as set out in clause 2.2), Purchaser

                                                                              27

                  Assets without adjustment of the Purchase Price on account of
                  such Material Title Defects;

         (b)      where the cumulative amount by which the value of the affected
                  interests has been reduced is, in Purchaser's opinion acting
                  reasonably, 5% or more of the Purchase Price (as set out in
                  clause 2.2):

                  (i)      the Parties may delay Closing to a mutually agreeable
                           time and date which in no event shall be later than
                           30 days after the Closing Date, in which case:

                           (A)      Vendor shall make further attempts to cure
                                    or remove the uncured Material Title
                                    Defects; and

                           (B)      when such mutually agreeable time and date
                                    arrives, the elections pursuant to this
                                    subsection 10.2(b) shall once again be made;
                                    or

                  (ii)     Purchaser may waive the uncured Material Title
                           Defects, in which case all of Vendor's interest in
                           and to the Assets shall be purchased by Purchaser
                           without an adjustment to the Purchase Price; or

                  (iii)    Purchaser may purchase Vendor's interest in and to
                           the Assets including Vendor's interest in and to the
                           Assets that are affected by the uncured Material
                           Title Defects, in which case the Purchase Price shall
                           be adjusted by the value mutually agreed upon by the
                           Vendor and the Purchaser for each affected interest,
                           acting reasonably, provided that in reaching this
                           decision, the Parties shall take into account the
                           probability of the Material Title Defect actually
                           materializing having regard to the particular
                           circumstances;

         (c)      where the cumulative amount by which the value of the
                  interests affected by the Material Title Defects has been
                  reduced is, in Purchaser's opinion acting reasonably, 20% or
                  more of the Purchase Price (as set out in clause 2.2), in
                  addition to the elections set out in subsection 10.2(b),
                  either Vendor or Purchaser may terminate this Agreement upon
                  written notice to the other Party, in which case the Parties
                  shall have no further obligation to each other hereunder,
                  except for obligations arising pursuant to clause 10.2.

10.3  RIGHTS OF FIRST REFUSAL

         (a)      If all or any portion of the Assets is subject to Rights of
                  First Refusal, then Vendor shall, upon receipt of Purchaser's
                  bona fide allocations of value, promptly serve all notices as
                  are required under the applicable Rights of First Refusal
                  provisions.

         (b)      If any of such Rights of First Refusal is exercised, Purchaser
                  shall purchase that portion of the Assets which are not
                  subject to such Rights of First Refusal that have been
                  exercised. In such event, the Purchase Price shall be adjusted
                  downward according to the amounts allocated to such of the
                  Assets which are subject to Rights of First Refusal which have
                  been exercised as determined pursuant to clause 3.3 (a) and
                  the sale of the balance of the Assets to Purchaser
                  contemplated hereby shall be completed on the Closing Date and
                  all reference herein to Assets shall be deemed to refer only
                  to the balance of the Assets. Provided if a Right of First
                  Refusal is considered a Material Title Defect in accordance
                  with subclause 1.1 and if such Right of First Refusal is
                  exercised then the value of such Right of first Refusal shall
                  be included in the calculation of the thresholds described in
                  Clause 10.2 hereto.

                               DISPUTE RESOLUTION

11.1     DISPUTES INITIALLY REFERRED TO MEDIATION

         The Parties will attempt to resolve any dispute arising hereunder
         through consultation and negotiation in good faith. If those attempts
         fail, a Party may, by notice to the other Party at any time during
         those negotiations, request the other Party to attempt to resolve that
         dispute through mediation, including with that notice sufficient detail
         to enable the other Party to understand the issues that remain in
         dispute. The Parties will attempt to agree on the selection of the
         mediator within 5 Business Days of receipt of that notice, unless a
         Party give notice to the other Party within that period that it is not
         prepared to proceed with mediation respecting that dispute. If the
         Parties are proceeding with a mediation and are unable to select a
         mediator within that period, either Party may thereafter deliver a
         written request to The Canadian Foundation for Dispute Resolution to
         attempt to select, within 2 Business Days of the receipt of that
         request, a mediator, qualified by education and experience to resolve
         that dispute, and the parties agree that the person so selected will be
         the mediator for the dispute. Unless otherwise agreed, the Parties will
         commence a mediation within 15 Business Days of the selection of the
         mediator, and the mediation process will continue until the dispute is
         resolved, a Party serves notice to the other Party that it wishes to
         terminate the mediation or the mediator makes a written determination
         that the dispute cannot be resolved through mediation, whichever first
         occurs. The Parties will each bear their own costs associated with a

                                                                              29

         mediation, but will share the common costs of a mediation equally,
         including, without limitation, the cost of the mediator.

11.2     ARBITRATION PROCEEDINGS

         A Party that wishes to pursue further proceedings after a failed or
         terminated mediation under Clause 11.1 must refer the dispute to
         binding arbitration for final resolution if the dispute pertains to (i)
         adjustments under Article 7; ii) the value or allocation to be use in a
         Right of First Refusal notice or iii) the value of Assets for which
         Title Defects remain uncured under Clause 10.2. Any such arbitration,
         and any other arbitration the Parties may agree to conduct hereunder,
         will be conducted under the Commercial Arbitration Rules of the
         Canadian Foundation for Dispute Resolution. Except as otherwise
         provided in this Clause, a Party may commence a court action with
         respect to any other dispute after a failed or terminated mediation.

11.3     LIMITATION PERIODS AND INTERIM RELIEF

         All limitation periods respecting the commencement of an action will be
         stayed during the period that the Parties are attempting to resolve a
         dispute under Clause 11.1 or 11.2. A Party may, at any time it believes
         it necessary to prtect its interest during that period, seek interim or
         provisional relief, in the form of a temporary restraining order,
         preliminary injunction or other interim equitable relief concerning a
         dispute under this Agreement, notwithstanding anything to the contrary
         in this Article.

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

              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

              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.

         c)   The effective date of an election to convert under sub clause (b)
              by the COC will be the first day of the calendar month following
              the calendar month in which Payout occurs.

         d)   In the event the Test Well is Abandoned prior to Payout, COC'S
              gross overriding royalty interest as set out in the Royalty
              Agreement will automatically convert to a 15% working interest in
              the Test Well spacing unit. The effective date of such conversion
              will be the date of Abandonment of the Test Well.

              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

              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

              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.
