          3.1.1 If, as of the Exchange Closing Date, a holder of a PPR has notified Seller that it elects to exercise its PPR with respect to the Properties to which its PPR applies (determined by and in accordance with the agreement in which the PPR arises), then Seller shall cause the Properties covered by that PPR to be transferred and conveyed from New GP back to Seller prior to the Exchange Closing Date, but effective as of the Effective Time (subject to the remaining provisions in this Article), such Properties shall be deemed for all purposes to constitute “Excluded Properties” and the Purchase Price shall be decreased by mutually agreed or arbitrated allocation of the Purchase Price attributable to such affected Property(ies). The remainder of the Properties not affected by an exercised PPR, a PPR for which the time to exercise has not expired, or a PPR for which Buyer did not request that a PPR notice be sent shall remain in New GP and subject to the consummation of the transactions contemplated by this Agreement. Upon the consummation of the sale of any Properties to the holder of such PPR any such Properties shall be deemed for all purposes to constitute “Excluded Properties.”

          3.1.2 After the Exchange Closing, if for any reason, the purchase and sale of the Properties covered by a PPR for which Buyer has requested preferential right to purchase notices be sent is not or cannot be consummated with the holder of the PPR that exercised its PPR as to such Properties within ninety (90) Days after such holder’s receipt of such notice, and such Properties were reconveyed to Seller by New GP, Seller may so notify Buyer and within ten (10) Business Days after Buyer’s receipt of such notice, Seller shall sell and convey to New GP and Buyer shall cause New GP to purchase and accept from Seller such Properties pursuant to the terms of this Agreement and for the mutually agreed or arbitrated allocation of the Purchase Price to such Properties adjusted pursuant to Section 2.2 (except adjustments pursuant to Section 2.2 with respect to any such Properties shall be made through the date of the re-conveyance of such Properties from Seller to Buyer).

If on the Exchange Closing Date any PPR for which Buyer has requested preferential right to purchase notices be sent has not been waived and the time to elect has not elapsed, the Exchange Closing shall proceed with the affected Properties included in New GP. If (i) the holder of a PPR validly exercises its PPR after the Exchange Closing (whether or not in response to a preferential right to

purchase notice), or (ii) the Exchange Closing occurs without such holder having waived such PPR or the time for such holder to exercise such PPR having not expired, and after the Exchange Closing, the holder of such PPR elects to exercise such PPR, then within ten (10) Business Days of (i) or (ii) above (x) Buyer shall cause New GP to, and Seller shall, execute such instruments as reasonably necessary to revoke, extinguish and/or rescind the original Contribution of such affected Property(ies) to New GP by Seller and/or reconvey such affected Properties to Seller, as appropriate (each hereinafter a “Rescission”), effective as of the Effective Time, (y) Seller shall cause an amount to be paid to Buyer equal to the mutually agreed allocation of the Purchase Price attributable to such affected Property(ies) adjusted as follows: (1) decreased by the amount of Operating Revenues attributable to such Properties after the Effective Time that are actually accounted for, collected or retained by New GP; (2) increased by the Charges attributable to such Properties after the Effective Time that are paid or accounted for by New GP; and (3) increased by the amount of taxes and assessments attributable to such Properties paid by New GP, Buyer and Buyer’s Affiliates in accordance with wire instructions to be provided by Buyer at least two (2) Business Days prior to the end of such ten (10) Business Day period and (z) any such Properties shall automatically, and without need to amend this Agreement, be deemed to constitute Excluded Properties for all purposes of this Agreement, and neither Buyer nor New GP shall have any further obligations with respect to such Excluded Properties.

          3.2 Consents to Assign.

          3.2.1 With respect to contracts, agreements, licenses and permits incident to ownership of or reasonably necessary for the operation of the Properties that require a novation or consent to assignment that has not been obtained prior to the Exchange Closing, Seller shall (i) continue, on an on-going basis to take all commercially reasonable steps and actions to obtain such consent or novation from the applicable Person(s) and (ii) hold such contracts, agreements, licenses and permits as bare trustee and receive and hold all proceeds, benefits and advantages accruing in respect of the contracts, agreements, licenses and permits fully for the benefit, use and ownership of the New GP and the Buyer and represent the New GP and the Buyer in matters under any agreement pertaining to such Properties as directed by Buyer until New GP is substituted and recognized as a party thereto in place of Seller, whether by novation, notice of assignment or otherwise. Seller shall forthwith deliver such proceeds to the New GP provided that Seller shall not be permitted to deduct from such proceeds any costs and expenses it incurs as a result of such delivery to Buyer, except to the extent that Buyer is in breach of its obligations under 3.2.3.

          3.2.2 In connection with its role as bare trustee described in Article 3.2.1, Seller shall deliver all Third Party notices to Buyer and New GP received by it in respect of such contracts, agreements, licenses and permits and, as agent of the New GP and Buyer, do and perform all such acts and things and execute and deliver all such agreements, notices and instruments as Buyer may reasonably request in writing for purposes of facilitating the exercise of rights incidental to the ownership

of such contracts, agreements, licenses and permits or required by any Governmental Authority.

          3.2.3 Buyer shall (i) reimburse Seller for all invoices, cash calls and bills paid by Seller on behalf of the New GP or Buyer which pertain to such contracts, agreements, licenses and permits and (ii) indemnify and hold harmless Seller to the extent that Seller suffers any actual Losses in its capacity as bare trustee under this Article 3.2, except to the extent that such losses are caused by the gross negligence or willful misconduct of any member of the Seller Group.

          3.3 Affiliate Consents and Waivers. Each Party shall cause its Affiliates to give any required consents and waive any PPR held by such Affiliates

ARTICLE IV
TITLE REVIEW

          4.1 Review of Title Records. After execution and delivery of this Agreement, Seller shall make available (during Seller’s regular business hours and at their current location) for Buyer’s review, Records in Seller’s or its Affiliates’ possession or under Seller’s or its Affiliates’ control relating to the Record Owner’s title to the Properties. If Buyer requests copies of title Records, Seller shall use its commercially reasonable efforts to provide the requested copies to Buyer at Buyer’s expense. Buyer shall conduct its review of Records in accordance with the terms of the Confidentiality Agreement.

CONDITION OF THE PROPERTIES

          5.1 Review of Environmental Materials, Inspection of Premises. After execution and delivery of this Agreement, Seller shall provide Buyer access (during Seller’s regular business hours) to Seller-operated (or New GP-operated, as applicable) Properties, and Seller and New GP will use its commercially reasonable efforts to obtain permission for Buyer to gain access to Third Party-operated Properties, to conduct a visual inspection of the same.

     (a) Any such inspection, including through the performance of Phase I Environmental Site Assessments, shall be conducted in accordance with the terms of the Confidentiality Agreement and subject to any releases or other agreements required by the operator of the Properties. Prior to the Exchange Closing, Buyer may not operate equipment, conduct testing, sample materials, perform Phase II environmental audits, or conduct invasive activities during such inspection

without Seller’s prior written consent, which consent shall not be unreasonably withheld. Buyer shall be responsible for arranging, at its own cost, transportation to and from the Properties. During the time period between the Exchange Closing and the Adverse Condition Diligence Review Deadline, Buyer may not conduct testing, sample materials, conduct invasive activities related to environmental conditions or perform Phase II environmental audits without in any case obtaining any applicable Third Party operator’s prior written consent, and without obtaining Seller’s prior written consent, which consent shall not be unreasonably withheld, unless recommended in a Phase I environmental audit or required by applicable Law in which case Seller’s prior written consent will not be required.

     (b) Buyer’s access to the Properties shall be at Buyer’s sole risk and expense; and Buyer hereby releases Seller Group from and shall (i) be liable to; and (ii) fully indemnify, defend, protect and hold Seller Group harmless from and against any and all Losses and Third Party Claims to the extent arising out of or connected with Buyer’s inspection of the Properties or travel to or from or presence on the Properties in connection with the transactions contemplated by this Agreement.

          5.2 Alleged Adverse Conditions.

     (a) As soon as reasonably practicable (and on an ongoing basis), but no later than one hundred twenty (120) Days after the Advance Closing Date (the “Adverse Conditions Diligence Review Deadline”), Buyer shall notify Seller of any conditions that might constitute Alleged Adverse Conditions. Buyer’s notice of such conditions must include (i) a description of each individual condition to which Buyer takes exception (including any and all supporting documentation) and (ii) an estimate of the costs Buyer in good faith attributes to bring such condition into compliance with applicable Environmental Laws. Seller and Buyer shall meet from time-to-time to attempt to agree on a resolution of Alleged Adverse Conditions.

     (b) If the Parties are unable to agree on resolution of any Alleged Adverse Conditions on or before sixty (60) Days after the Adverse Condition Diligence Review Deadline, Seller has the option, in its sole discretion, to either (i) bring the Alleged Adverse Condition into compliance with Environmental Laws (as in effect as of the Exchange Closing Date); or (ii) deliver to Buyer an indemnity agreement in favor of Buyer Group, upon terms reasonably acceptable to Buyer, fully releasing Buyer Group from and protecting, defending, indemnifying and holding Buyer Group harmless from and against all Environmental Claims arising from or relating to such Alleged Adverse Condition.

     (c) If Seller elects, at its sole cost, to bring any Alleged Adverse Condition into compliance with Environmental Laws (as in effect as of the Exchange Closing Date), Seller may, by notice to Buyer, elect to continue attempting to remediate such condition to completion for up to one hundred

eighty (180) Days after the Adverse Condition Diligence Review Deadline. Seller’s remediation of any Alleged Adverse Condition may not materially interfere with the use of operation of the affected Property. If Seller does not remediate an Alleged Adverse Condition within such period, Buyer shall give Seller written notice of such failure or non-completion and within five (5) Business Days following the earlier to occur of the date that (i) Seller and Buyer agree in writing on the existence and value of the Alleged Adverse Condition or (ii) resolution of any dispute regarding the existence or value of the Alleged Adverse Condition in accordance with the provisions of Article 5.4, Seller shall pay to Buyer an amount equal to the value of such Alleged Adverse Condition, if any, as so agreed or determined.

     (d) If an Alleged Adverse Condition can be remediated, the adjustments or payments with respect to that Alleged Adverse Condition shall not exceed the Prudent Cost Response.

     (e) Notwithstanding anything contained in this Agreement to the contrary, Buyer shall not be entitled to an adjustment or other remedy relating to any Alleged Adverse Condition unless and until the aggregate value of all Aggregate Transaction Claims exceeds the Deductible, and then only to the extent such Aggregate Transaction Claims exceeds the Deductible; and Buyer shall be solely responsible for and bear all costs and expenses associated with any and all Aggregate Transaction Claims up to the Deductible. No payment shall be due with respect to any Alleged Adverse Condition for which Seller, at its option, delivers to Buyer an indemnity agreement in favor of Buyer in accordance with Article 5.2(b) nor shall any Alleged Adverse Condition for which Seller has indemnified Buyer be included as an Aggregate Transaction Claim.

          5.3 Waiver. Buyer (on behalf of Buyer Group and their successors and assigns) waives for all purposes all objections and claims (whether known or unknown) associated with environmental conditions (including Alleged Adverse Conditions) except for (a) Buyer’s rights with respect to Seller’s indemnity under Article 8, (b) Alleged Adverse Conditions Buyer raised to Seller by proper notice within the applicable time period specified in, and as otherwise required by, Article 5.2, and (c) such Alleged Adverse Conditions as are settled by written agreement of the Parties or determined in accordance with Article 5.4.

          5.4 Dispute Resolution. If the Parties are unable to agree upon the existence, validity or value or cure of any Alleged Adverse Condition (“Adverse Condition Dispute”), then, within two hundred ten (210) Days after the Adverse Condition Diligence Review Deadline, such dispute shall be exclusively and finally resolved pursuant to this Article 5.4 by a single arbitrator, who shall be an environmental attorney with at least ten (10) years experience in oil and gas environmental matters, has not at any point in the past ten (10) years represented or been adverse to any Party and is selected by mutual agreement of Buyer and Seller within fifteen (15) Days after the delivery and receipt by either Party of a notice of an Adverse Condition Dispute, and absent such agreement, by the Calgary, Alberta office of the ADRI (the “Environmental Referee”). Except as otherwise provided in the preceding sentence, any Adverse Condition Dispute arbitration proceeding shall be conducted in accordance with Article

19. To the extent that the award of the Environmental Referee with respect to any Alleged Adverse Condition value is not taken into account as an adjustment to the Purchase Price pursuant to Article 6, then within ten (10) Days after the Environmental Referee delivers written notice to Buyer and Seller of the award with respect to an Alleged Adverse Condition value, and subject to the other terms hereof and after taking into account all previous adjustments to the Purchase Price in accordance with Article 6, (i) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Referee to Seller and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Environmental Referee to Buyer.

ARTICLE VI

          6.5.2 As soon as reasonably practicable, but no later than forty-five (45) Days after Seller receives Buyer’s written report, the Parties shall meet to attempt to agree on any adjustments to the Final Accounting Statement. If the Parties fail to agree on final adjustments within that forty-five (45) Day period, either Party may submit the disputed items to the Accounting Referee. The Parties shall direct the Accounting Referee to resolve the disputes within thirty (30) Days after its receipt of relevant materials pertaining to the dispute (and the Parties agree to use their respective reasonable efforts to deliver such materials promptly to the Accounting Referee).

          6.5.3 The Final Accounting Statement, whether as agreed between the Parties or as determined by a decision of the Accounting Referee, shall be binding on and non-appealable by the Parties. The Accounting Referee shall act as an expert for the limited purpose of determining the specific disputed matters submitted by either Party and may not award damages or penalties to either Party

with respect to any matter. Seller and Buyer shall share equally the Accounting Referee’s fees and expenses.

          6.5.4 Any amounts owed by one Party to the other under the Final Accounting Settlement shall be paid within thirty (30) Days after the earlier of (i) the date that the amounts are agreed by the Parties, and (ii) the date the Parties receive the Accounting Referee’s decision; and the revenues and expenses included in the Final Accounting Settlement (including any and all Operating Revenues and Charges received and booked by Seller prior to Seller’s delivery of the Final Accounting Statement to Buyer) shall be final and binding on the Parties and not subject to further review, audit or arbitration.

ARTICLE VII
LOSS, CASUALTY AND EXPROPRIATION

          7.1 Notice of Loss. Seller shall promptly notify Buyer of all instances of Casualty Loss that occur and become known to Seller between the date of this Agreement and the Exchange Closing.

          7.2 Casualty Loss. If, prior to the Exchange Closing, any Properties are impacted by a Casualty Loss, Seller and Buyer shall meet to attempt to agree on an adjustment to the Purchase Price reflecting the reduction in value of the Properties because of such Casualty Loss. For this purpose, “reduction in value” is based on the principle that Seller should generally bear the costs of repairing the Properties to the state existing immediately prior to the Casualty Loss, but if such repair results in equipment or facilities that are newer than or upgraded from that which existed immediately prior to the Casualty Loss, Buyer should bear a portion of such costs as is equitable given the benefit to Buyer of such newer or upgraded equipment, Business Assets or Facilities. No adjustment associated with a Casualty Loss will exceed the value claimed by Buyer in the applicable claim to Seller of such Casualty Loss.

          7.2.1 If the Parties are unable to agree on resolution of a Casualty Loss, the Parties shall consummate the Exchange in accordance with the terms hereof with the Purchase Price being decreased by the arithmetic average of the good faith estimates of the reduction in value associated with such Casualty Loss by both Buyer and Seller; provided, however, that within thirty (30) Days after the Exchange Closing Date, either Party may initiate binding arbitration in accordance with Article 19 to resolve the dispute. Any claim with respect to a Casualty Loss not referred to arbitration within thirty (30) Days following the Exchange Closing (or, with respect to any Casualty Loss for which Seller provides notice that it will continue attempting to cure after the Exchange Closing, within thirty (30) Days after the one hundred eighty (180) Day cure period following the Exchange Closing has expired) shall be deemed waived by Buyer for all purposes.

          7.2.2 Seller shall retain any and all insurance proceeds and other payments associated with or attributable to any Casualty Loss.

     (a) any Claim under Article 8.2 or 8.3, if Buyer has not provided Seller with a Claim Notice within twenty-four (24) months from and after the Exchange Closing with respect to such Claim (other than (i) Claims under Article 8.2(b) with respect to a breach of Article 10.1.23 for which a Claim Notice must be given within seventy-two (72) months from and after the Exchange Closing, (ii) any Claim under (A) Article 8.2(b) with respect to the breach of any of the Seller’s covenants in Articles 3, 6, 12.15.6, 12.19, 17, 20 or Exhibit “H” or relating to a breach of Articles 10.1.8 or 10.1.9 and (B) Article 8.3(b), each of which shall survive indefinitely, and (iii) Claims under Article 8.2(b) with respect to a breach of Articles 10.1.2 or 10.1.19, which shall survive the Exchange Closing for the applicable Tax limitation period; and

The Indemnifying Party’s failure to respond in writing to a Claim Notice within the thirty (30) Day period shall be deemed an election by the Indemnifying Party not to assume responsibility for defense and payment of the Claim.

In all instances the Indemnified Party may employ separate counsel and participate in defense of a Claim, but the Indemnified Party shall bear all fees and expenses of counsel employed by the Indemnified Party.

          12.1 Subsequent Operations. Seller makes no representations or warranties to Buyer as to transferability or assignability of operatorship of any Properties that Seller currently operates. Rights and obligations associated with operatorship of the Properties are governed by operating and similar agreements covering the Properties and will be decided in accordance with the terms of such agreements.

          12.2 Buyer’s Assumption of Obligations. If the Exchange Closing occurs, and subject only to Seller’s indemnities in Article 5.1 and 5.2, 8.2, 8.3, 8.6, 12.15.4 and 20.3, and except for other matters that are Seller’s or its Affiliates’ express obligations under this Agreement, Buyer agrees that upon the Contribution of the Properties to the New GP, the New GP shall assume, shall pay and shall timely perform and discharge all of Seller’s or the New GP’s duties and obligations associated with the Properties arising prior to, on or after the Exchange Closing (including any and all contractual duties and obligations arising therefrom) (collectively, the "Assumed Obligations”), and in fulfilling these obligations, New GP shall comply with all Laws.

          12.3 Asbestos and NORM. The Properties may currently or have in the past contained asbestos and NORM, and special procedures associated with assessment, remediation, removal, transportation or disposal of asbestos and NORM may be necessary, and Buyer acknowledges and agrees as follows from and after the Exchange Closing:

          12.3.1 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer accepts sole responsibility for and agrees to pay any and all costs and expenses associated with assessment, remediation, removal, transportation and disposal of asbestos and NORM associated with the Properties, and may not claim the fact that assessment, remediation, removal, transportation or disposal of asbestos and NORM are not complete or that additional costs and expenses are required in connection with assessment, remediation, removal, transportation or disposal of asbestos and NORM as an Alleged Adverse Condition or the basis for any other redress against Seller or its Affiliates, and Buyer (on behalf of Buyer Group and their successors and assigns and the New GP) irrevocably waives any and all Losses and Third Party Claims they may have against Seller Group associated with the same; and

          12.3.2 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer releases Seller Group from and shall: (i) be liable to; and (ii) fully protect, defend, indemnify, and hold Seller Group harmless from and against any and all Losses and Third Party Claims relating to, arising out of, or connected with, directly or indirectly, the assessment, remediation, removal, transportation and disposal of asbestos and NORM associated with the Properties, no matter whether arising before, on or after the Effective Time. This indemnity and defense obligation will apply regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law or other fault of Seller Group, or any pre-existing defect. For the removal of doubt, Buyer’s release under this Article 12.3.2 does not prevent Buyer from asserting the existence of an Alleged Adverse Condition under Article 5.2. for asbestos or NORM that is, as of a date prior to the Exchange Closing, in a condition that violates existing Laws. The preceding sentence shall in no way expand Buyer’s rights under Article 5.2 or diminish Buyer’s waiver contained in Article 5.3.

          12.4 Plugging and Abandonment. The Properties may contain ▇▇▇▇▇ and facilities that have been shut in or temporarily or permanently abandoned including such ▇▇▇▇▇ as are listed on Schedule 12.4, and Buyer acknowledges and agrees as follows from and after the Exchange Closing:

          12.4.1 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer hereby expressly assumes and accepts sole and exclusive responsibility for and agrees to pay or cause the New GP to pay all costs and expenses associated with Plugging and Abandonment of all ▇▇▇▇▇ and facilities associated with the Properties (whether or not listed on Schedule 12.4), and may not claim the fact that Plugging and Abandonment operations are not complete or that additional costs and expenses are required to complete Plugging and Abandonment operations as an Alleged Adverse Condition or the basis for any other redress against Seller or its Affiliates, and Buyer (on behalf of Buyer Group and their successors and assigns and the New

GP) irrevocably waives any and all Losses and Third Party Claims it may have against Seller Group associated with the same; and.

          12.4.2 Except with respect to a breach by Seller of any of its representations or warranties contained in Article 10, as limited by Article 8, Buyer releases and shall cause the New GP to release Seller Group from and shall: (i) be liable to; and (ii) fully protect, defend, indemnify, and hold Seller Group harmless from and against any and all Losses and Third Party Claims relating to, arising out of, or connected with, directly or indirectly, Plugging and Abandonment operations, no matter whether arising before on or after the Effective Time. This indemnity and defense obligation will apply regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect. For the removal of doubt, Buyer’s release under this Article 12.4 does not prevent Buyer from asserting the existence of an Alleged Adverse Condition under Article 5.2 for any condition that, as of a date prior to Closing, violates existing Laws with respect to Plugging and Abandonment operations. The preceding sentence shall in no way expand Buyer’s rights under Article 5.2 or diminish Buyer’s waiver contained in Article 5.3.

          12.5 [Reserved]

          12.6 [Reserved]

          12.7 Suspense Funds. Buyer acknowledges that Suspense Funds may exist as of the Effective Time. Seller shall transfer to New GP all Suspense Funds held by Seller as operator of any of the Properties and the obligations with respect thereto. This transfer shall be accounted for in the Final Accounting Statement.

          12.7.1 Buyer (on behalf of Buyer Group and their successors and assigns) shall cause the New GP to accept sole responsibility for and agrees to pay all costs and expenses associated with Suspense Funds, and Buyer (on behalf of Buyer Group and their successors and assigns) irrevocably waives any and all claims it may have against Seller Group associated with the same; and

          12.7.2 Buyer releases Seller Group from and shall: (i) be liable to; and (ii) fully protect, defend, indemnify and hold Seller Group harmless from and against any and all Losses and Third Party Claims relating to, arising out of, or connected with, directly or indirectly, the Suspense Funds, no matter whether arising before, on or after the Effective Time when asserted. This indemnity and defense obligation applies regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect.

          12.8 Schedules and Post-Signing Cooperation.

          12.8.1 Seller shall prepare, supplement or amend the following of Seller’s Schedules (collectively, the “Pending Schedules”) within the following time periods (each such period, a “Schedule Cure Period”) with respect to any matter hereafter arising or discovered which, if existing or known on the date hereof, would have been required to be set forth or described in Seller’s Schedules: (i) in the case of all Material Contracts described in Article 10.1.11 other than those described in subparagraph (g) thereof, five (5) Business Days after the date hereof, (ii) in the case of all Material Contracts described in subparagraph (g) of Article 10.1.11, ten (10) Days after the date hereof, (iii) in the case of all items required to be identified by Seller on Schedule 10.1.26, thirty (30) Days after the date hereof, (iv) in the case of all items required to be identified by Seller on Schedule 10.1.15, ten (10) Days after the date hereof, and (v) in the case of all items required to be identified by Seller on Schedule 10.1.14, ten (10) Business Days..

          12.8.3 Upon the expiration of each of the Pending Schedule’s respective Schedule Cure Periods, such Pending Schedules shall be deemed completed for all purposes under this Agreement.

          12.8.4 During any Schedule Cure Period, the Parties agree that Buyer Group shall assist Seller in compiling the Pending Schedules and in connection therewith, Seller shall provide Buyer with all necessary access to provide such assistance; provided, however, that in no event shall Buyer’s provision of assistance in any way affect Buyer’s rights to indemnification under Article 8.

          12.9 Transition Agreement. Buyer and Seller shall execute and deliver the Transition Agreement at the Exchange Closing Date. On the Exchange Closing Date, Buyer, the New GP and Seller shall further execute notice letters customarily given under the Contracts in connection with a transfer of ownership of the Properties.

Seller shall reasonably assist Buyer in contacting the relevant Third Parties, but Buyer shall be solely responsible for and shall bear all costs and transfer and other fees required to obtain assignments or new licenses or other agreements in connection with Third Party Seismic Data. With respect to any of Seller’s wholly owned seismic data pertaining to the Properties, New GP and Seller shall execute and deliver the Seismic License at the Exchange Closing.

          12.11 Interim Period.

     (c) encumber, sell, lease or otherwise dispose of any of the Properties having a value in excess of Five Hundred Thousand U.S. Dollars ($500,000) (excluding sales of hydrocarbons therefrom), except to the extent replaced by equivalent property or to the extent used, consumed or abandoned in the normal operations of Seller’s business; or

               12.11.3 Buyer acknowledges Seller owns undivided interests in certain of the Properties and that Seller does not operate all of the Properties, and

Buyer agrees that the acts or omissions of Third Party working interests owners (including Third Party operators) shall not constitute a breach of the provisions of this Article 12.11, nor shall any action required by a vote of working interest owners constitute such a breach so long as Seller or New GP has voted its interest in a manner that complies with the provisions of this Article 12.11. Furthermore, Seller shall not be deemed or held to be in breach of any of Seller’s representations, warranties, covenants or other agreements contained in this Agreement to the extent that any such breach arises out of or in connection with the actions of Buyer or Buyer’s Affiliates as operators or co-owners of any of the Properties prior to the Exchange Closing.

               12.11.4 During the Interim Period, (a) Seller shall cause Newco and the New GP not to take and (b) subject to the last sentence of this Article 12.11.4, Seller shall not take, any of the following actions without obtaining the prior written consent of Buyer, not to be unreasonably withheld, or as expressly permitted pursuant to the Debenture:

Provided the Exchange Closing occurs, Buyer shall be responsible for the purchase of all Third Party-Owned Software that is needed or is appropriate for Buyer’s or the New GP’s operation of the Properties following the Exchange Closing, as currently operated by Seller. Seller will use reasonable efforts to procure for Buyer or the New GP the rights (including seeking and obtaining relevant vendor consents) to access and use (or permit Seller to access and use on Buyer’s behalf) all Third Party-Owned Software during the Transition Period only, and Buyer, provided the Exchange Closing occurs, shall bear all costs and fees, if any, to procure such consents and shall reimburse Seller in the Final Accounting Settlement for any such costs or fees incurred by Seller in connection therewith.

In such case, on the Exchange Date, Buyer shall or shall cause the New GP to satisfy the deposit requirements of the ERCB in order to approve any of those licence transfers to the New GP. Buyer further covenants to comply with all conditions imposed by the ERCB in respect of such transfers.

     (b) Subject to the approval of Seller’s working interest partners in the particular Property (to the extent such working interest partners have the contractual right to grant or deny consent) Seller, as soon as reasonably practicable following the Exchange Closing Date, shall prepare and electronically submit an application to the ERCB for the transfer of the ▇▇▇▇▇, and the Pipelines and Facilities, if any, held in the name of the Seller on behalf of the New GP and Buyer shall electronically ratify and sign such application.

approve the licence transfer, Buyer shall or shall cause the New GP to covenant to immediately make such deposit.

     (e) If the New GP fails to make a deposit it is required to make under Article 12.16(d) within ten (10) days of Buyer’s receipt of notification from ERCB that such deposit is required, Seller shall have the right, but not the obligation, to make such deposit.

The cost incurred by Seller and their Affiliates in providing the financial Records (including fees of accountants, consultants and outside counsel) to Buyer and assisting Buyer as provided in this Article shall be borne by Buyer. Buyer releases Seller Group from and shall: (i) be liable to; and (ii) fully protect, defend, indemnify and hold Seller Group harmless from and against any and all claims, liabilities, losses or damages (including costs of investigation and attorneys’ and experts’ fees and expenses) relating to, arising out of, or connected with, directly or indirectly, the preparation or furnishing of any such records to Buyer, any actions, representations or certifications of Seller’s and its Affiliates’ personnel or auditors with respect to the information contained in such Records, or Buyer’s use of the information contained in such Records, the inclusion of such financial Records in any debt or equity offering documents or related materials, regardless of cause or of any negligent acts or omissions (including sole negligence, concurrent negligence or strict liability), breach of duty (statutory or otherwise), violation of Law, or other fault of Seller Group, or any pre-existing defect.

Adjusted Purchase Price and (ii) such fair market value will be allocated eighty percent (80%)% to Canadian resource property and twenty percent (20%) to depreciable property (with substantially all of such allocation to Class 41 property), each within the meaning of the Canadian Income Tax Act.

ARTICLE XVII
TERMINATION

          17.1 Grounds for Termination. This Agreement may be terminated (except for the individual provisions specifically referenced in Article 17.2 below) at any time prior to the Exchange Closing (unless another date is stated below):

          17.1.1 by the Parties’ mutual written agreement;

          17.1.2 by any Party, if consummation of the transactions contemplated by this Agreement would violate any non-appealable final order, decree or judgment of any Governmental Authority of competent jurisdiction enjoining, restraining, prohibiting or awarding substantial damages in connection with the (a) contemplated transfer of the Target Interests to Buyer in accordance with the terms hereof, (b) the Contribution of the Properties by Seller to the New GP in accordance with the terms hereof, or (c) consummation of the transactions contemplated by this Agreement and the Debenture;

          17.1.3 by Seller, if Buyer refuses or fails to fulfill its obligations under Article 2.4;

          17.1.4 by either Party, if at any time prior to the applicable Closing Date, such Party becomes aware that any condition precedent to such Party’s obligation to consummate either of the Closings cannot be satisfied prior to the applicable Closing Date, provided, however, that the terminating Party shall have given the other Party at least five (5) Business Days in which to attempt to cure the situation and at the end of such cure period, the relevant condition precedent remains unable to be satisfied prior to the applicable Closing Date;

          17.1.5 notwithstanding anything contained in this Agreement to the contrary, by either Seller or Buyer, if the Exchange has not occurred on or before the Maturity Date (unless such date is extended by mutual agreement of the Parties); provided, however, that no Party shall have the right to terminate this Agreement pursuant to this Article 17.1.5 if such Party or its Affiliates are at such time in material breach of any provision of this Agreement; or

          17.1.6 by either Party, if the Termination Defect Amount meets or exceeds the requisite amount set forth in the definition of such term.

          17.2 Effect of Termination; Failure to Close. Except as otherwise provided in this Article 17.2 if this Agreement is terminated in accordance with Article 17.1, such termination is without liability to either Party, except performance of obligations in this Article 17.2, and Articles 5.1(b), 17.3, 17.4, 19.1, 19.2, 20.1, 20.3, 20.7, 20.8, 20.10, 20.12, 20.13, 20.14, 20.15, and 20.18 all of which provisions survive termination of this Agreement. If, upon the Maturity Date, the Exchange has not occurred, Seller shall pay the amount due under the Debenture in accordance with its terms. If, upon the Maturity Date, the Exchange has not occurred because of Buyer’s material breach of this Agreement, or Buyer’s failure or refusal to consummate the Exchange Closing that is not permitted by the terms of this Agreement, Buyer shall pay to Seller as Seller’s exclusive remedy an amount equal to five percent (5%) of the Purchase Price together with Computed Interest thereon from July 30, 2010 to and including the Day immediately preceding such Maturity Date (the “Reverse Breakup Fee”). In such event, in satisfaction of its obligations under the Debenture, Seller shall pay to Buyer in immediately available funds an amount equal to (i) the aggregate Principal Amount together with all accrued interest thereon owed by Seller to Buyer under the Debenture minus (ii) the Reverse Breakup Fee, in which case, the Reverse Breakup Fee shall be set off against the payments owed to Buyer by Seller under this Agreement. The Reverse Breakup Fee, paid in accordance with the terms of this Article 17.2, shall constitute the Parties’ genuine pre-estimate of liquidated damages suffered by Seller in such event and shall not be a penalty. No default or failure by Buyer to perform any of its obligations hereunder shall relieve or release Seller of or from any of its obligations under the Debenture including the obligation to pay Buyer the Principal Amount together with all interest accrued thereon up to and including the Maturity Date; provided that, Seller may retain and set off the Reverse Breakup Fee from the payments due as aforesaid. Each Party agrees that notwithstanding anything in this Agreement to the contrary, in the event that the Reverse Breakup Fee is paid to Seller in accordance with this Article 17.2, the payment of such Reverse Breakup Fee shall be the sole and exclusive remedy of any member of the Seller Group

against any member of the Buyer Group, and in no event will any member of the Seller Group seek to recover any other money damages or seek any other remedy based on a claim at law or in equity with respect to (1) any loss suffered, directly or indirectly, as a result of the failure of the transactions contemplated hereby to be consummated, (2) the termination of this Agreement, (3) any liabilities or obligations arising under this Agreement, or (4) any claims or actions arising out of or relating to any breach, termination or failure of or under this Agreement, and no member of the Buyer Group shall have any further liability or obligation to any member of the Seller Group relating to or arising out of this Agreement or the transactions contemplated hereby. The provisions for payment of the Reverse Breakup Fee as liquidated damages in this Article 17.2 have been included because, in the event of termination of this Agreement as described in Article 17.2, both Buyer and Seller agree that the actual damages that would be incurred by Seller are reasonably expected to approximate the amount of the Reverse Breakup Fee and because the actual amount of such damages would be difficult, if not impossible, to measure precisely and Buyer waives any and all rights to claim otherwise, and Seller shall have no liability or obligation to any member of the Buyer Group relating to or arising out of the Reverse Breakup Fee.

          17.3 Dispute over Right to Terminate. If there is a dispute between the Parties over the termination of or over the right of a Party to terminate this Agreement, (i) the Advance Closing shall not occur on the Advance Closing Date or (ii) the Exchange Closing shall not occur on the Exchange Closing Date, as applicable, and the Party that disputes the right of the other Party to terminate is entitled, within thirty (30) Days after the applicable Closing Date, to initiate litigation to resolve the dispute, unless the Parties mutually agree in writing to extend such time. If the Party that disputes the other Party’s right to terminate this Agreement does not initiate litigation within the thirty (30) Day period, this Agreement shall be deemed properly terminated as of the original date of termination, and the Party that disputes or has a right to dispute termination of this Agreement, on behalf of itself, its Affiliates, and the officers, directors, agents, employees, successors and assigns of itself and its Affiliates, irrevocably waives any and all claims it and they may have against the terminating Party for termination of this Agreement.

          17.4 Confidentiality. Notwithstanding the termination of this Agreement or any other provision of this Agreement to the contrary, the terms of the Confidentiality Agreement remain in full force and effect, provided that upon the earlier to occur of the Exchange or the payment by Seller to Buyer of all amounts owing under the Debenture in accordance with the terms thereof, the Confidentiality Agreement shall terminate to the extent (and only to the extent) it applies to the Target Interests conveyed at the Exchange Closing and the Properties intended to be Contributed to the New GP in accordance with the terms hereof.

ARTICLE XVIII
TAXES

          18.1 Access to Tax Records. Buyer and Seller shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding (each a “Tax Proceeding”) with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such Tax Proceeding and making

employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Buyer and Seller agree (i) to retain all books and records with respect to Tax matters pertinent to the Properties relating to any taxable period beginning before the Exchange Closing Date until the expiration of the statute of limitations (and, to the extent notified by Buyer or Seller, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Taxing Authority, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Buyer or Seller, as the case may be, shall allow the other party to take possession of such books and records. Buyer and Seller further agree, upon request, to use their best efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

ARTICLE XIX
ARBITRATION

          19.1 Friendly Consultation. In the event of any Arbitrable Dispute, the Parties shall attempt in the first instance to resolve such dispute through friendly consultations between the Parties. The Parties agree to attempt to resolve all Arbitrable Disputes arising hereunder promptly, equitably and in a good faith manner.

          19.2 Arbitration.

     (a) The Parties shall attempt to resolve any Arbitrable Dispute promptly by negotiation between representatives who have authority to settle the controversy. Either Party may give the other Party written notice of any Arbitrable Dispute not resolved in the normal course of business.

The notice and response shall include (a) a statement of that Party’s position and a summary of arguments supporting that position, and (b) the name and title of that Party’s representative and of any other Person who will accompany the representative. Within thirty (30) Days after delivery of the initial notice, the representatives of both Parties shall meet at a mutually acceptable time and place, and thereafter continue to meet as often as they reasonably deem necessary, to use their good faith and reasonable efforts to attempt to resolve the dispute. All negotiations pursuant to this clause shall be confidential and shall be treated as without prejudice compromise and settlement negotiations for purposes of applicable rules of evidence.

     (b) If an Arbitrable Dispute has not been resolved within sixty (60) Days after delivery of the initial notice set forth in Article 19.2.1, or if the Parties failed to meet within thirty (30) Days after delivery of such notice, then, at the request of either Party, such Arbitrable Dispute shall be submitted to binding arbitration to be conducted under the ADRI Rules, except as modified herein or in a subsequent written agreement between the Parties. In the event of any conflict between the provisions of the procedure set forth in this Article 19 (the

“Arbitration Procedure”) and the ADRI Rules, the provisions of this Article 19 shall prevail.

     (c) The process to resolve an Arbitrable Dispute by arbitration in accordance with this Article 19 shall be commenced by the delivery of a Notice of Request to Arbitrate in accordance with the ADRI Rules.

     (d) The location of the arbitration and all hearings shall be Calgary, Alberta. The language of the arbitration shall be English.

     (e) The arbitration shall be determined by three arbitrators (the “Arbitration Tribunal” or each an “Arbitrator”). The Arbitration Tribunal shall consist of two (2) Party-appointed Abitrators, one (1) appointed by Sellers and one (1) appointed by Buyers and a third neutral Arbitrator. No arbitrator may be a current or former officer, director, employee or consultant of, or other person who has had business or personal relationship with, a Party or any of its Affiliates. Each Arbitrator must be an lawyer qualified to practice in Calgary, Alberta and must have not less than seven (7) years experience in the Canadian oil and gas industry. The Parties shall jointly select the neutral Arbitrator to act as Chair of the Tribunal within ten (10) Business Days of the submission to arbitration. In the absence of the Parties agreeing upon the Chair, the Chair shall be appointed by the ADRI upon either Party making such a request of ADRI.

     (f) Within ten (10) Business Days of the appointment of the Chair, each Party shall then be entitled to nominate one Arbitrator to serve on the Arbitration Tribunal. In the absence of a Party making its nomination within that period, the other Party that has made its nomination shall be entitled to request the ADRI to make the appointment of the third Arbitrator.

     (g) Where any appointment is to be made by the ADRI and the ADRI or any lawful successor organization ceases to exist or is unable or unwilling to act, then such appointment shall be made by a Justice of the Court of Queen’s Bench of the Province of Alberta sitting in Calgary, in accordance with the provisions of the Arbitration Act (Alberta).

     (h) Upon the appointment of the Arbitration Tribunal they shall proceed to determine the Arbitrable Dispute. However, questions of procedure or any interlocutory applications regarding procedural matters shall be heard and decided by the Chair or, if the Chair so directs, the Arbitration Tribunal.

     (i) The arbitration hearing shall be concluded as soon as possible but not later than ninety (90) Days after the appointment of the Arbitration Tribunal and the Arbitration Tribunal shall render its final award and provide reasons for that award within thirty (30) Days following the conclusion of the hearing.

     (j) The Arbitration Tribunal shall have the jurisdiction to award damages, declaratory judgments, specific performance and injunctive and other equitable relief, but the Arbitration Tribunal will not have the power to modify or

amend, in any respect, the provisions of this Agreement or, award punitive or exemplary damages, or to award consequential damages.

     (k) The Arbitration Tribunal shall be entitled to apportion the costs of arbitration in their award, or a subsequent award with respect to costs, in such manner as the Arbitration Tribunal deems just and reasonable taking into account the circumstances of the Arbitrable Dispute, the conduct of the parties during the arbitration proceeding, and the result of the arbitration.

     (l) An award of the Arbitration Tribunal will be final and binding upon the Parties, may be filed in any court of competent jurisdiction and may be enforced by any Party as a final judgment in such court.

     (m) In addition to the confidentiality provision set out in the ADRI Rules, the Parties (and any Affiliates who are parties to the arbitration), the witnesses and the Arbitrators shall agree not make use of the documents, materials or information disclosed by or on behalf of any other Party to the arbitration, the transcripts of the proceedings or any award of the Arbitrators for any purpose other than the arbitration of the Arbitrable Dispute. At the request of the Party that produced any documents or other materials in the arbitration, the other parties and the Arbitrators shall return all originals and any copies of such documents and materials, provided that each Party may retain one copy of all such documents and materials in the confidential files of its legal department only for the purpose of verification of its compliance with this clause. Each Party to the arbitration and each Arbitrator shall be responsible for compliance with this provision and the confidentiality provisions of the ADRI Rules by any person to whom disclosure is made by them.

     (n) In the event that the subject matter of the Arbitrable Dispute gives rise to the possible participation of one or more third parties (other than Affiliates) as plaintiffs or defendants who are not bound to and refuse to participate in an arbitration consistent with the terms of this Arbitration Procedure, then either by the written agreement of the Parties or upon the application of a Party to the Arbitration Tribunal where the Arbitration Tribunal concludes that:

     (i) one or more third parties would be proper parties as plaintiffs or defendants to the Arbitrable Dispute by virtue of there being common questions of fact or law in the Arbitrable Dispute and the matter involving the third party or parties,

     (ii) the absence of the third party or parties in the arbitration could reasonably result in either Party becoming subject to conflicting awards or judgments, and

     (iii) such an outcome could reasonably result in a Party suffering material prejudice, then the arbitration shall be terminated and the Parties shall resolve the Arbitrable Dispute by litigation.

          19.3 Interim Remedies. Before a notice to arbitrate is given or prior to the selection of the Arbitrators, nothing contained herein shall prevent a Party from applying to a court that would otherwise have jurisdiction for provisional or interim measures. After the Arbitrators have been selected, they shall have sole jurisdiction to hear such applications, except that any measures ordered by the Arbitrators may be immediately and specifically enforced by a court otherwise having jurisdiction over the Parties.

          20.5 Further Assurances. After the Exchange Closing and on an on-going basis: (a) Buyer shall and shall cause the New GP to execute and deliver or use reasonable
