         negligence or wilful misconduct of the Vendor, or any of its directors,
         officers, agents or employees.

8.2      ENVIRONMENTAL MATTERS AND ABANDONMENT AND RECLAMATION OBLIGATIONS

         Provided that Closing has occurred, Purchaser shall:

         (a)      be liable to the Vendor for all of its Losses; and, in
                  addition

         (b)      indemnify and hold harmless Vendor and each of its directors,
                  officers, agents and employees from and against all Losses

         in respect of all Environmental Liabilities and all Abandonment and
         Reclamation Obligations howsoever and by whomsoever caused and whether
         they occur or arise in whole or in part prior to, on or subsequent to
         the Effective Time. Purchaser shall not be entitled to exercise and
         hereby waives any rights or remedies Purchaser may now or in the future
         have against Vendor in respect of such Environmental Liabilities or the
         Abandonment and Reclamation Obligations, whether such rights and
         remedies are pursuant to the common law or statute or otherwise,
         including without limitation, the right to name Vendor as a third party
         to any action commenced by any Third Party against Purchaser. Nothing
         in this section, however, will operate to limit any representation or
         warranty made by the Vendor under subsection 6.1(w) with respect to the
         environmental condition of the Assets or to affect the Purchaser's
         right to make a claim against the Vendor for breach thereof, pursuant
         to section 7.1, subject to section 6.4 and sections 7.3.

8.3      VENDOR'S GENERAL INDEMNITY

         Provided Closing has occurred, Vendor shall:

         (a)      be liable to the Purchaser for all of Purchaser's Losses; and
                  shall, in addition,

         (b)      indemnify and hold harmless Purchaser and each of its
                  directors, officers, agents and employees from and against all
                  Losses

         as a direct result of any matter attributable to the Assets and
         occurring or accruing prior to the Effective Time, except any Losses of
         Purchaser insofar as they are caused by the gross negligence or wilful
         misconduct of the Purchaser, or any of their respective directors,
         officers, agents or employees.

                             RIGHTS OF FIRST REFUSAL

9.1      RIGHT OF FIRST REFUSALS

         It is the Parties' belief that there are no ROFRs that are applicable
         to the transactions contemplated by this Agreement. Notwithstanding
         this, the Parties agree that if contrary to their common understanding
         and belief with respect to this issue, if any Third Party is able to
         establish its entitlement to a ROFR with respect to any of the Assets,
         or any interest therein, as a result of the completion of the
         transactions provided for in this Agreement, and is able to enforce the
         same, Purchaser shall comply with such ROFR.

         which the Assets are subject:

         (a)      operate and maintain the Assets in a proper and prudent manner
                  in accordance with good oil and gas industry practices and in
                  material compliance with all Applicable Law;

                  in the Title and Operating Documents and any other agreements
                  and documents to which the Assets are subject,

         provided that where Vendor is not the operator, Vendor shall be
         obligated to do only that which a prudent non-operator would be
         expected to do in similar circumstances in accordance with accepted
         industry practices.

10.2     CONSENT OF PURCHASER

         Notwithstanding section 10.1, from the date hereof until the Closing

         provided, will be provided in a timely manner:

                  emergency or in respect of amounts which Vendor is committed

         (a)      Following Closing, Vendor shall hold its title to the Assets

                  necessary Specific Conveyances including notifications,
                  registrations and other steps required to transfer such title
                  to Purchaser have been completed;

         (b)      From the date hereof, Vendor shall represent Purchaser in all
                  matters arising under a Title and Operating Document until
                  Purchaser is substituted as a party thereto in the place of
                  Vendor, whether by novation, notice of assignment or otherwise
                  and, in furtherance thereof:

                  (i)      all payments relating to the Assets received by
                           Vendor following Closing pursuant to the Title and
                           Operating Document, other than those to which Vendor

                  (ii)     Vendor shall forward all statements, notices and

                           Assets to Purchaser (including, without limitation,


                                     - 27 -

                           any independent operation notices and any potential
                           acquisitions pursuant to any active areas of mutual
                           interest in respect of the Assets) promptly following

                  (iii)    Vendor shall forward to other parties to the Title
                           and Operating Document such notices and elections
                           pursuant to such Title and Operating Document
                           pertaining to the Assets as Purchaser may reasonably
                           request (including, without limitation, any elections
                           made by Purchaser in respect of any independent

                  extent caused by the gross negligence or wilful misconduct of
                  Vendor or its servants, agents or employees and except for
                  Vendor's overhead and general administrative costs. Acts or
                  omissions taken by Vendor or its servants or agents with the
                  approval of Purchaser shall not constitute gross negligence or
                  wilful misconduct for purposes of this subsection.

10.4     TRANSFER OF OPERATORSHIP

         Purchaser acknowledges that Vendor may not be able to transfer

         reasonable things as Purchaser may request in order to obtain the
         appropriate consents and approvals for the assignment and transfer to
         Purchaser of operatorship of those of the Assets which Vendor currently
         operates.
