3.1       Preferential Rights of Purchase and Consents

     (a)  If any of the Assets are subject to a preferential right of purchase

          where, in the Seller's opinion, acting reasonably, the value is
          unreasonable.

     (c)  If the holder of any preferential right to purchase any of the Assets
          exercises such right, or a third party required to give a necessary
          consent refuses to give such consent, such right or refusal, as the
          case may be, shall be considered a Title Defect for the purposes of
          Subclause 4.2(b)

3.2       Operatorship and Third Parties

     (a)  at the offices of the Seller, in Calgary, Alberta during normal
          business hours, provide the Purchaser and its nominees reasonable
          access to the Seller's records, files and documents directly relating
          to the Assets, for the purpose of the Purchaser's review of the Assets
          and the Seller's title thereto, including, without limitation, the
          Leases and applicable operating agreements, unit agreements,
          overriding royalty agreements and production sale contracts; and

     (b)  provide the Purchaser and its nominees with a reasonable opportunity
          to inspect the Assets at the Purchaser's sole cost, risk and expense,
          insofar as the Seller can reasonably provide access to the Assets.

4.2       Title Defects

     (a)  Any review of the Seller's title to the Assets shall be undertaken by
          the Purchaser with reasonable diligence.  Not later than five (5) days
          prior to the Closing Date, the Purchaser shall give the Seller written
          notice of the Title Defects which the Purchaser does not waive.  Such
          notice shall specify such Title Defects in reasonable detail, the
          Assets directly affected thereby (the "Affected Assets") and the
          Purchaser's requirements for the rectification or curing thereof.  The
          Seller shall thereupon diligently make reasonable efforts to cure such
          Title Defects not later than two (2) days prior to the Closing Date.

     (b)  Insofar as the Title Defects described in the Purchaser's notice have
          not been cured to the Purchaser's reasonable satisfaction, but subject
          to Clause 9.5 with respect to preferential purchase rights and
          required consents, the Purchaser may elect, on or before the Closing
          Date by written notice to the Seller, to do one of the following:

          (i)   delay the Closing Date to such later date as is agreed by the
                Parties, so as to provide the Seller with additional time to
                cure the remaining Title Defects;

          (ii)  waive such uncured Title Defects and proceed with Closing;

                                     - 10 -

 
          (iii) proceed only with the purchase of only those Assets not directly
                affected by the Title Defects which have not been waived by the
                Purchaser (the "Unaffected Assets"), in which case the Purchase
                Price shall be reduced by the portion of the Purchase Price
                applicable (as of the Effective Date) to the Affected Assets, by
                agreement of the Parties, or by Article 12; or

          (iv)  terminate this Agreement, if the portion of the Purchase Price
                applicable to the Affected Assets is ten percent (10%) or more
                of the Purchase Price, by agreement of the Parties, or by
                Article 12, as the case may be.

          However, failure of the Purchaser to make such election at or before
          the Closing Date shall be deemed to be an election pursuant to
          Paragraph (ii) of this Subclause 4.2(b).

     (c)  In the event that the portion of the Purchase Price applicable to the
          Affected Assets for the reduction provided for in Paragraph
          4.2(b)(iii) is to be determined pursuant to Article 12:

          (i)   then prior to proceeding with the purchase of the Unaffected
                Assets, the Purchaser shall deduct from the Purchase Price an
                amount equal to the Purchaser's good faith estimate of the
                portion of the Purchase Price applicable to the Affected Assets
                and deposit such amount in trust with a Canadian chartered bank
                in an interest bearing account; and

          (ii)  the funds retained in trust pursuant to Paragraph (a) of this

                the extent that the amount held in trust varies from such
                determination, any excess or deficiency and the interest which
                accrued thereon shall either be paid by the Purchaser to the
                Vendor within fifteen (15) days of such determination or be
                retained by the Purchaser, as applicable.

     (d)  If a portion of the Assets is excluded from the Closing pursuant to
          this Clause:

          (i)   the terms "Assets", "Lands", "Leases", "Miscellaneous
                Interests", "Petroleum and Natural Gas Rights" and "Tangibles"

                matter of those terms with respect to which Closing occurs; and

          (ii)  the term "Purchase Price" shall be construed to be the amount of

                                  -----------

5.1       Benefits and Obligations to be Apportioned

     (a)  All benefits and obligations of any kind and nature accruing, payable,
          paid, received or receivable with respect to the Assets (including,
          without limitation, maintenance, development, capital and operating
          costs, ARTC credits or any other tax or royalty credits, advances,
          payments with respect to the Permitted Encumbrances, proceeds from the
          sale of production, expenses, and fees for processing, treating,
          transportation and compression, accounts receivable and incentives
          accruing pursuant to the Regulations) shall be apportioned, as of the
          Effective Date, between the Seller and the Purchaser, on an accrual
          basis, in accordance with generally accepted accounting principles,
          subject to the provisions of this Agreement.  All such benefits and
          obligations accruing up to the Effective Date shall be for the
          Seller's account and all those accruing after the Effective Date shall
          be for the Purchaser's account.  All costs of whatever nature
          pertaining to work performed or goods or services provided with
          respect to the Assets prior to the Effective Date shall be borne by
          the Seller, notwithstanding that such costs may be payable in whole or
          in part after the Effective Date.

     (b)  Notwithstanding adjustments that may be made pursuant to Subclause
          5.1(a) relating to proceeds from the sale of production, there will be
          a price adjustment for natural gas sold by the Seller with respect to
          the Assets between the Effective Date and the Closing Date.  The
          Seller will pay to the Purchaser $0.3675/GigaJoule based on the sales
          volume of natural gas between the Effective Date and the Closing Date.
          Pursuant to Subclause 5.2(a) below, the amount of this adjustment will
          be estimated by Seller and included on the interim statement of
          adjustments presented at Closing.

     (c)  All rentals and all similar payments required to preserve any of the
          Leases and all taxes (other than income taxes and taxes based on the
          volume of the production of Petroleum Substances) levied with respect
          to the Assets shall be apportioned between the Seller and the
          Purchaser on a per diem basis as of the Effective Date, unless and to
          the extent that such apportionment is waived by the Seller.

                                     - 12 -

 
     (d)  All Petroleum Substances including natural gas, oil and liquified
          petroleum products, which were produced, but not sold, as of the
          Effective Date shall be credited to the Seller.

5.2       Adjustments to Accounts

     (a)  An interim accounting and adjustment may, upon the request of either
          Party, be conducted for Closing, based on the Seller's and the
          Purchaser's good faith estimate of all adjustments to be made for the
          transactions herein pursuant to this Article, and a final accounting
          and adjustment shall be conducted within twelve (12) months of the
          Closing Date.  Subject to Subclauses (b) and (c) of this Clause, the
          Parties shall not be obligated to make any adjustments after such
          twelve (12) month period unless such adjustment has been specifically
          requested, by notice, within such period.  All adjustments shall be
          settled by payment by the Party required to make payment hereunder
          within thirty (30) days of being notified of the determination of the
          amount owing.

     (b)  During the twelve (12) month period following the Closing Date, the
          Purchaser may audit the books, records and accounts of the Seller
          respecting the Assets, for the purpose of effecting adjustments
          pursuant to this Article.  Such audit shall be conducted upon
          reasonable notice to the Seller at the Seller's or Seller's attorney's
          offices during the Seller's normal business hours, and shall be
          conducted at the sole expense of the Purchaser.  Any claims or
          discrepancies disclosed by such audit shall be made in writing to the
          Seller within one (1) month following the completion of such audit,
          and the Seller shall respond in writing to any claims or discrepancies
          within one (1) month of the receipt of such claims.  To the extent
          that the Parties are unable to resolve any outstanding claims or
          discrepancies disclosed by such audit within one (1) month of the
          Seller's response thereto, such audit exceptions shall be resolved
          pursuant to Article 12.

     (c)  Purchaser is a publicly traded entity and as such is obligated to
          abide by certain rules and regulations promulgated by the SEC.  In the
          event that SEC regulations require an independent audit of Seller's
          books, records, assets, and accounts, relating to the required Assets,
          Seller agrees to cooperate fully with Purchaser to complete such
          audit.  Seller's cooperation shall include making available on a
          timely basis all of the Seller's original accounting records with
          respect to the Assets and related information, and Seller's personnel
          needed to answer direct inquiries.  Seller further agrees to provide
          such reasonable further written representation as Purchaser may
          require regarding any future audit with respect to the Assets.

     (d)  Notwithstanding the preceding subclauses of this Clause and Clause
          7.3, any adjustments resulting from joint venture audits, royalty
          audits or Crown royalty invoices relating to the Assets:

                                     - 13 -

 
          (i)    relating to the period prior to the Effective Date and for
                 which audit queries are outstanding at the Closing date;

          (ii)   that occur after the Closing Date but not later than two years
                 after the Closing Date or within the applicable period in the
                 governing operating agreements included in Miscellaneous
                 Interests, whichever is later, in the case of joint venture
                 audits;

          (iii)  that occur after the Closing Date but not later than four years
                 after the Closing Date in the case of the Crown royalty
                 invoices; or

          (iv)   that occur after the Closing Date but not later than four years
                 after the Closing Date in the case of royalty audits

          shall be made as they are established and payment for them shall be
          made by the Party required to make payment hereunder within 30 days of
          being notified in writing of the determination of the amount owing.

     (e)  Subject to Subclause 4.2(c), any amount owing to a Party by the other
          Party pursuant to any provision of this Agreement after Closing and
          remaining unpaid after thirty (30) days prior written request from one
          party to the other, shall bear compound interest, as computed monthly,
          from the day such amount was due to be paid until the day such amount
          was paid, at the rate of two (2%) percent per annum above the rate
          designated as the prime rate for Canadian dollar commercial loans by
          the main branch of the Canadian Imperial Bank of Canada in Calgary,
          regardless of whether such Party has given the other Party prior
          notice of the accrual of interest hereunder.

     (f)  All adjustments provided for in this Article shall be adjustments to
          the Purchase Price.

6.1       Assets to be Maintained in Proper Manner

     Possession of the Assets shall not pass to the Purchaser until after
     Closing on the Closing Date.  The Seller shall maintain the Assets on

     shall maintain insurance respecting the Assets until the Closing Date.

6.2       Seller as Agent

     (a)  Insofar as the Seller maintains the Assets and takes actions with
          respect thereto on behalf of the Purchaser pursuant to this Article,
          the Seller shall be deemed to have been the agent of the Purchaser
          hereunder.  The Purchaser ratifies all actions which the Seller takes
          or refrains from taking pursuant to the terms of this Article, with
          the intention that all such actions shall be deemed to be those of the
          Purchaser;

     (b)  The Purchaser shall indemnify the Seller and its directors, officers,
          servants, agents, consultants or employees against all liabilities,
          losses, costs (including legal costs on a solicitor-client basis),
          claims or damages which the Seller or its directors, officers,
          servants, agents, consultants or employees may suffer or incur as a
          result of maintaining the Assets as the agent of the Purchaser
          pursuant to this Article, insofar as such liabilities, losses, costs,
          claims or damages are not a direct result of the gross negligence or
          willful misconduct of the Seller or its directors, officers, servants,
          agents, consultants or employees.  An action or omission of the Seller
          or its directors, officers, servants, agents, consultants or employees
          shall not be regarded as gross negligence or willful misconduct,
          however, to the extent it was done or omitted to be done in accordance
          with the instructions of or with the concurrence of the Purchaser.

6.3       Restrictions on Conduct of Business

     While acting as agent for the Purchaser pursuant to this Article, the
     Seller shall not, without the prior written consent of the Purchaser:

          (a) voluntarily assume any obligation or commitment with respect to
              the Assets, where the Seller's share of the expenditure associated
              with such obligation or commitment is estimated to exceed
              $5,000.00;

          (b) surrender or abandon any of the Assets;

          (c) resign, or agree to resign as Operator of Assets;

          (d) amend any agreement or enter into any new agreement respecting the

              exercise of any right arising as a result of the ownership of the
              Assets;

          (f) sell, transfer or otherwise dispose of the Assets, or any of them,
              except as may be required by the Seller to comply with its
              obligations respecting any preferential rights, as provided in
              Article 3; or

                                     - 15 -

 
          (g) grant a security interest or any encumbrance with respect to any
              of the Assets.

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

                         LIABILITY AND INDEMNIFICATION
                         -----------------------------

8.1       Responsibility of Seller

     Subject to Clauses 8.3 and 8.4 and provided that Closing has occurred, the
     Seller shall:

     (a)  be liable to the Purchaser for all losses, costs, damages and expenses
          whatsoever which the Purchaser may suffer, sustain, pay or incur; and

     (b)  indemnify and save the Purchaser and its directors, officers,
          servants, agents, consultants and employees harmless from and against
          all claims, liabilities, actions, proceedings, demands, losses, costs,
          damages and expenses whatsoever which may be brought against or
          suffered by the Purchaser, its directors, officers, servants, agents,
          consultants or employees or which they may sustain, pay or incur

     as a direct result of any matter or thing arising out of, resulting from,
     attributable to or connected with the Assets and occurring prior to the
     Effective Date, except any losses, costs, damages, expenses, claims,
     liabilities, actions, proceedings and demands to the extent that the same
     either are reimbursed (or reimbursable) by insurance maintained by the
     Purchaser or are caused by the gross negligence or willful misconduct of
     the Purchaser, its directors, officers, servants, agents, consultants,
     employees or assigns.  The indemnity granted by the Seller herein, however,
     is not a title warranty and does not provide an extension of any
     representation or warranty contained in Clause 7.1.  Notwithstanding any
     provision herein, the liability of the Seller and the indemnity hereby
     granted by the Seller to the Purchaser shall only apply with respect to
     claims made within one (1) year following the Closing Date.

8.2       Responsibility of Purchaser

     Subject to Paragraph 8.4 and provided that Closing has occurred the
     Purchaser shall:

     (a)  be liable to the Seller for all losses, costs, damages and expenses
          whatsoever which the Seller may suffer, sustain, pay or incur; and

     (b)  indemnify and save the Seller and its directors, officers, servants,
          agents, consultants and employees harmless from and against all
          claims, liabilities, actions, proceedings, demands, losses, costs,
          damages and expenses whatsoever which may be brought against or
          suffered by the Seller, its directors, officers, servants, agents,
          consultants or employees or which they may sustain, pay or incur;

     as a direct result of any matter or thing arising out of, resulting from,
     attributable to or connected with the Assets and occurring subsequent to
     the Effective Date, except any losses, costs, damages, expenses, claims,
     liabilities, actions, proceedings and demands to 

                                     - 22 -

 
     the extent that the same either are reimbursed (or reimbursable) by
     insurance maintained by the Seller or are caused by the gross negligence or
     willful misconduct of the Seller, its directors, officers, servants,
     agents, consultants, employees or assigns. Notwithstanding the foregoing,
     however, the assumption of liability, indemnification and release provided
     for in this Clause shall not apply to any losses, costs, claims, damages,
     expenses and liabilities suffered, sustained, paid or incurred by the
     Seller that would have been disclosed to the Purchaser prior to Closing but
     for a breach of any of the Seller's representations and warranties in
     Clause 7.1 or that result from the Seller's breach of any covenants or
     other obligations hereunder, and nothing in this Clause shall operate
     either to limit any representation or warranty made by the Seller pursuant
     to Clause 7.1 or to affect the Purchaser's right to make a claim against
     the Seller for the breach of such a representation or warranty. Further,
     the responsibility of the Purchaser prescribed by this Clause does not
     provide an extension of any representation or warranty contained in Clause
     7.2. Notwithstanding any provision herein, the liability of the Purchaser
     and the indemnity hereby granted by the Purchaser to the Seller shall only
     apply with respect to claims made within one (1) year following the Closing
     Date.



8.3       Limit on Seller's Responsibility

     In no event shall the total of the liabilities and indemnities of the
     Seller under this Agreement exceed the Purchase Price, except in the event
     of fraud.

8.4       Environmental Indemnity

     Notwithstanding the foregoing provisions of this Article but subject to the
     Seller's representations and warranties in Clause 7.1, and pursuant to
     Paragraph 7.3, the Purchaser acknowledges that with respect to the
     environmental condition of the Assets, it is acquiring the Assets on an "as
     is" basis.  The Purchaser acknowledges that it is familiar with the
     condition of the Assets, including the past and present use of the Lands
     and the Tangibles, that the Seller has provided the Purchaser with a
     reasonable opportunity to inspect the Assets at the sole cost, risk and
     expense of the Purchaser (insofar as the Seller could reasonably provide
     access) and that the Purchaser is not relying upon any representation or
     warranty of the Seller as to the condition, environmental or otherwise, of
     the Assets.  Provided that Closing has occurred, the Purchaser further
     agrees that it shall:

     (a)  be solely liable and responsible for any and all losses, costs,
          damages and expenses which the Seller may suffer, sustain, pay or
          incur; and

     (b)  indemnify and save the Seller and its directors, officers, servants,
          agents, consultants and employees harmless from any and all claims,
          liabilities, actions, proceedings, demands, losses, costs, damages and
          expenses whatsoever which may be brought against or suffered by the
          Seller, its directors, officers, servants, agents, consultants or
          employees or which they may sustain, pay or incur;

                                     - 23 -

 
     as a direct result of any matter of thing arising out of, resulting from,
     attributable to or connected with any Environmental Liabilities pertaining
     to the Assets, regardless of the date from which they may have accrued.
     Once Closing has occurred, the Purchaser shall be solely responsible for
     all Environmental Liabilities respecting the Lands, including, without
     limitation, the abandonment of all Wells and the reclamation of the surface
     lands pertaining to the Lands, and the Purchaser hereby releases the Seller
     from any claims the Purchaser may have against the Seller with respect to
     all such liabilities and responsibilities.  Notwithstanding the foregoing,
     however, the assumption of liability, indemnification and release provided
     for in this Clause shall not apply to any Environmental Liabilities that
     would have been disclosed to the Purchaser prior to Closing but for a
     breach of any of the Seller's representations and warranties in Clause 7.1
     and nothing in this Clause shall operate either to limit any representation
     or warranty made by the Seller pursuant to Clause 7.1 or to affect the
     Purchaser's right to make a claim against the Seller for the breach of such
     a representation or warranty.

8.5       No Merger of Legal Responsibilities

     The liabilities and indemnities created in this Article shall be deemed to
     apply to, and shall not merge in, all assignments, transfers, conveyances,
     novations, trust agreements and other documents conveying any of the Assets
     from the Seller to the Purchaser, notwithstanding the terms of such
     assignments, transfers, conveyances, novations and other documents, the
     Regulations or any rule of law or equity to the contrary, and all such
     rules are hereby waived.

8.6       Substitution and Subrogation

     Insofar as is possible, each Party shall have full rights of substitution
     and subrogation in and to all covenants, representations and warranties by
     others previously given or made in respect of the Assets or any of them.
