If the gas offered for delivery hereunder by Seller shall fail at any time to conform to any of the specifications identified in Section 9.1, then Buyer shall notify Seller of such deficiency and thereupon may, at Buyer's option, refuse to purchase such gas pending correction by Seller. Upon Seller's failure promptly to remedy any such deficiency in quality, Buyer may purchase such gas and may make changes necessary to bring such gas into conformity with such specifications, and Seller shall reimburse Buyer for any reasonable expense incurred by Buyer in effecting such changes. 22 Execution Copy ARTICLE 10. MEASUREMENT OF GAS 10.1 Seller and Buyer agree that the measurement of the gas to be delivered by Seller and received by Buyer at the Delivery Point shall be determined by the measurement provisions set forth in the TCPL Tariff governing the transportation of the gas sold hereunder. ARTICLE 11. POSSESSION AND TITLE 11.1 Possession of and title to gas sold by Seller to Buyer hereunder shall pass from Seller to Buyer at the Delivery Point. Until the gas reaches the Delivery Point, Seller shall be deemed to be in control of and have title to and possession of and be responsible for such gas, after which Buyer shall be deemed to be in control of and possession of and have title to and be responsible for such gas. ARTICLE 12. SELLER'S REPRESENTATIONS AND WARRANTIES 12.1 Seller represents and warrants that: (i) it has full right and authority to enter into this Contract; (ii) subject to the applicable laws, rules and regulations, the Leases are in full force and effect and are capable of being maintained and will be maintained by Seller in full force and effect for as long as gas can be produced in paying quantities; and (iii) Seller has good title to and the right to sell the gas to be sold and delivered hereunder and all such gas is owned or authorized to be sold by Seller and will be delivered by Seller free from all Alberta taxes, liens, charges and adverse claims whatsoever, including liens to secure payment of any taxes. Seller shall at all times have the obligation to make settlements for all royalties and overriding royalties due and payments to the mineral and royalty owners under the Leases and 23 Execution Copy other documents, as may appear of record or otherwise be binding upon Seller and in accordance with the terms of the respective Leases and other documents, and to make settlements with all other persons having any interest in the gas sold hereunder. Seller agrees to indemnify Buyer and save it harmless from all suits, actions, debts, accounts, damages, costs, losses, liabilities and expenses arising from or out of claims of any other charges thereon, which attach before the title passes to Buyer or which may be levied and assessed upon the sale thereof to Buyer and are the responsibilities of Seller hereunder. 12.2. Seller represents that it is entitled to drill for, produce, and sell gas from Seller's Lands. Seller warrants and represents that Seller will, subject to and in accordance with the provisions of this Contract, equip and tie-in its wells and construct or install its facilities so as to be able to commence and continue delivery of gas to Buyer in accordance with the provision of this Contract. Subject to Article 13, Seller covenants to diligently drill, develop and produce Seller's Reserves to the extent required by Section 14.4 such that Deliverable Gas at the time of each Determination referred to in Article 14 will be sufficient for Seller to supply the Maximum Daily Quantity to Buyer from Seller's Reserves for at least four (4) contract years following each such Determination. Upon Commencement of Firm Deliveries, Seller shall deliver to Buyer sufficient gas to meet Seller's obligations under this Contract from Seller's Lands or from such other sources available from time to time to Seller provided that Seller has the right and necessary regulatory approvals to deliver to Buyer from such other sources. 12.3. 12.3.a. Seller dedicates and commits exclusively to the performance of this Contract all of Seller's Reserves and represents to Buyer that such Seller's Reserves will at all times (i) be sufficient in quantity and quality to satisfy provincial and federal regulatory authorities in respect of maintaining a provincial removal permit which satisfies the requirements of Section 6.3.a and a 24 Execution Copy federal export license for the full term and volumes contemplated in this Contract; (ii) contain Initial Recoverable Reserves in an amount not less than 2,747.9 106m3 (97.01 Bcf) in accordance with Section 14.3; and (iii) contain Deliverable Gas in an amount not less than the Minimum Deliverable Gas Amount in accordance with Section 14.4. Seller's Reserves shall not be named or used by Seller or any third party to support any removal permit or export license other than the joint removal permit and the export license to be obtained by Buyer based on Seller's Reserves to permit gas purchased hereunder to be removed from the Province of Alberta and delivered to Buyer. 12.3.b. Buyer is hereby authorized by Seller to identify and commit Seller's Reserves in order to jointly obtain with Seller or extend a provincial removal permit and to obtain on its own behalf or extend a NEB export license in respect of the Maximum Daily Quantity for the term of this Contract. Seller agrees to cooperate with Buyer and provide Buyer with such further information concerning Seller's Reserves as may be required for such purposes. 12.3.c. During the term of this Contract, Seller shall not sell, assign, transfer or otherwise dispose of any interest in Seller's Reserves without obtaining Buyer's prior written consent, such consent not be unreasonably withheld. Seller acknowledges that a reasonable condition to Buyer providing any such consent would be the assumption (by novation or other means acceptable to Buyer) by such third party of that portion acquired by such third party of Seller's obligations to Buyer under this Contract. 25 Execution Copy 12.3.d. Seller represents that no finding of producer support under the Alberta Natural Gas Marketing Act nor any joint working interest owner approval is or will be necessary for Seller to fulfill its obligations under the terms and conditions of this Contract. ARTICLE 13. SELLER'S RESERVATIONS 13.1 Seller hereby expressly reserves unto itself the following rights: 13.1.a. to operate Seller's Lands and Seller's Reserves free from any controls by Buyer and in such manner as Seller in its sole discretion may deem advisable consistent with good oilfield practice, including but not restricted to, the right to determine when and whether any additional well will be drilled, when and whether any well will be reworked or recompleted, when and whether any lease or well cannot or has ceased to produce gas in paying quantities having regard to Seller's cost of producing, processing and delivering such gas and when and whether any lease or well is to be released or abandoned or surrendered; 13.1.b. to determine the manner in which the quantities of gas to be delivered hereunder shall be produced by Seller from the various wells on Seller's Lands; and 13.1.c. to deliver to any lessors of the Leases the quantities of gas which Seller is obligated to deliver in kind to such lessors. 13.2 Seller reserves unto itself the following quantities of gas from Seller's Lands: 13.2.a. such gas (other than gas used as fuel in thermal recovery operations) as may be required for the development and operation of Seller's Lands, including but not limited to gas 26 Execution Copy for gas lifting operations and return to reservoir, so long as such gas lifting operations and return to reservoir do not interfere with Seller's ability to deliver gas under this Contract; and 13.2.b. such gas as may be required for the operation of separator equipment, compressor stations and other facilities through which the gas to be delivered hereunder may be processed or handled; provided, however, that if other gas or gas constituents are processed through any of the foregoing facilities, an equitable amount of such other gas or gas constituents shall be used in such facilities. 13.3 For the purpose of causing the gas to be delivered to meet the quality specifications set forth in Article 9 hereof, Seller may extract or permit the extraction of non-hydrocarbon and hydrocarbon constituents as are required to be extracted in order for the gas to meet such specifications. 13.4. Seller shall not be required to produce wells in excess of the lesser of: (a) their respective allowable rates of flow as fixed by law or regulatory bodies; (b) their maximum efficient rates of flow as determined by Seller; or (c) in instances of wells jointly operated with other parties, the current rate of production permitted Seller under the terms of applicable operating agreements. 13.5 13.5.a. Seller shall have the right on any day to make Third Party Sales in an amount up to the Maximum Daily Quantity provided (i) Seller shall have met Buyer's Daily Nomination on such day and (ii) neither a Reserve Deficiency nor a Deliverability Deficiency that must be cured pursuant to Section 14.4 then exists. Seller may accumulate its daily right to make Third Party Sales during each calendar month, and amounts so accumulated may be sold on any 27 Execution Copy day during such calendar month and the following calendar month in addition to the daily limit for such day. With respect to any amount for which Seller has accumulated its daily right to make Third Party Sales, Seller shall have no further right to make Third Party Sales of such amount after the two month period applicable to such amount has elapsed. Notwithstanding the foregoing, Seller shall in no event make Third Party Sales before meeting Buyer's Daily Nominations on any day, and in no event shall Seller make Third Party Sales in an amount exceeding a quantity equal to (a) the product of (i) the number of days in the relevant two-month period and (ii) the Maximum Daily Quantity, less (b) the sum of any Daily Nominations made by Buyer in such months. 13.5.b. In addition to Third Party Sales as provided in Section 13.5.a., Seller shall have the right to make Excess Third Party Sales on any day provided (i) Seller shall have met Buyer's Daily Nomination on such day and (ii) neither a Reserve Deficiency nor a Deliverability Deficiency that must be cured pursuant to Section 14.4 then exists. 13.6 Seller may pool or unitize any of Seller's Lands with other properties and, if any of Seller's Lands are so pooled or unitized, this Contract will cover Seller's interest in the unit derived therefrom and the gas attributable thereto; provided, however, that in the event that such pooling or unitization is entered into voluntarily by Seller, it shall protect Buyer's rights hereunder and prevent an appreciable reduction or postponement in the Article 2 quantities of gas to be sold by Seller to Buyer. Buyer and Seller agree that, from time to time as appropriate, they shall negotiate in good faith to agree upon appropriate action under or with respect to this Contract to maintain or improve 28 Execution Copy alignment of deliverability of Seller's Reserves, consistent with the efficient administration of Seller's lands and reserves and the full performance of this Contract, and subject to the receipt of all necessary regulatory approvals, which necessary regulatory approvals shall not adversely affect any existing approval required under this Contract. ARTICLE 14. ASSURANCES OF GAS SUPPLY; SUBSTITUTE GAS SUPPLY 14.1 On or before the date upon which Seller proposes to make a reduction pursuant to Section 14.9 and on or before each September 1 during the term of the Contract, Seller shall provide to Buyer, at Seller's expense, a written reserves and deliverability report ("Report"). Each Report shall be prepared by McDaniels Associates ("McDaniels") or another independent reserve engineer reasonably acceptable to Buyer. Seller shall notify Buyer in writing not less than three (3) months prior to the delivery of a Report if Seller intends to employ an independent reserve engineer other than McDaniels and Buyer shall have thirty (30) days to accept or reject said independent reserve engineer. In addition, Buyer may inform Seller that McDaniels, or an independent reserve engineer subsequently selected, as the case may be, is no longer an acceptable independent reserve engineer with respect to the next due Report upon written notice given not later than the February 1 of the year in which such Report is to be delivered. If Seller and Buyer are unable to agree upon a substitute independent reserve engineer, the selection of an independent reserve engineer shall be submitted to arbitration pursuant to Article 20. If Buyer and Seller are unable to agree upon a substitute independent reserve engineer, or if arbitration has not determined a substitute independent reserve engineer, in either case, by September 1 of any year, Seller shall nevertheless provide the Report due on such September 1, which Report shall have been prepared by the independent reserve engineer which prepared the prior year's Report. Failure to agree on an 29 Execution Copy independent reserve engineer, by negotiation or arbitration, shall not excuse Seller's failure to provide a Report on or before September 1 of each year. Each Report shall redetermine and set forth the Initial Recoverable Reserves as of the first day of the contract year immediately following the Report. Each Report shall also determine and set forth the Deliverable Gas as at the date of such Report under this Contract for each contract year for the remainder of the Contract term. Each Report shall also set forth Seller's best estimate of the cost to drill and develop additional lands and reserves necessary to cure a Deliverability Deficiency (as defined in Section 14.4) (the "Tie-in Cost") together with, when applicable, the information required under Section 14.4 and Section 14.9. 14.2 Buyer shall, within 45 days of receipt of a Report, advise Seller whether such Report is acceptable to Buyer and if it is acceptable to Buyer, such Report shall become the "Determination" for purposes of this Article 14. In the event that Buyer advises Seller that such Report is not acceptable, Seller and Buyer shall endeavor to agree upon a mutually acceptable Initial Recoverable Reserves, Deliverable Gas, estimate of the Tie-in Cost, and land removal determination. In the event that Seller and Buyer do so agree, their determination shall be in writing, shall set forth the Initial Recoverable Reserves, Deliverable Gas, estimate of 30 Execution Copy the Tie-in Cost, and land removal determination, and shall be the "Determination" for purposes of this Article 14. In the event that Seller and Buyer are unable to agree upon a mutually acceptable Initial Recoverable Reserves, Deliverable Gas, estimate of the Tie-in Cost, and land removal determination, either party may, within 90 days of delivery of Report, refer the matter to arbitration pursuant to Article 20 hereof. An Initial Recoverable Reserves, Deliverable Gas, estimate of the Tie-in Cost, and land removal determination by arbitration shall be in writing, shall set forth the Initial Recoverable Reserves, Deliverable Gas, estimate of the Tie-in Cost, and land removal determination and shall be the "Determination" for purposes of this Article 14. 14.3 If a Determination states that the Initial Recoverable Reserves are less than 2,747.9 106m3 (97.01 Bcf), as adjusted to reflect on a proportionate basis, any decrease in the Maximum Daily Quantity under the Contract (a "Reserves Deficiency"), then, within twelve (12) months of the first day of the contract year immediately following the Report upon which the Determination is based, Seller shall dedicate additional lands and reserves to this Contract as needed to cure the Reserves Deficiency. 14.4. 14.4.a. If any Determination indicates that Deliverable Gas during the first full five (5) contract years of 12 months each detailed in the Report upon which the Determination is based is less than the Minimum Deliverable Gas Amount (a "Deliverability Deficiency"), then, within twelve (12) months of the first day of the contract year immediately following such Report, Seller shall either (i) increase the deliverability from Seller's Reserves and, if necessary, dedicate additional lands and reserves to this Contract, as needed to cure the Deliverability Deficiency or (ii) provide a binding written certification that it reasonably believes that it can obtain gas from other sources ("Alternate Sources") to meet its obligations under this Contract and that it has the right and necessary regulatory approvals to deliver such gas to Buyer (an "Alternate Source Notice"). 14.4.b. The Alternate Source Notice shall provide in reasonable detail the facts underlying such Notice and shall identify the extent to which Seller intends to rely on Alternate 31 Execution Copy Sources. Seller shall not be entitled to seek excuse from its obligation to cure a Deliverability Deficiency as otherwise permitted pursuant to Section 14.4.c. for any period for which an Alternate Source Notice is given. All of the terms and conditions of this Contract (including, without limitation, Seller's duty to supply the Maximum Daily Quantity and the pricing terms with respect thereto) shall continue unaffected by the Alternate Source Notice. Seller shall not be entitled to deliver an Alternate Source Notice for any Deliverability Deficiency relating to volumes attributable to Excess Third Party Sales. If for any reason, Seller is unable to meet at any time Buyer's nomination for gas up to the Maximum Daily Quantity and Seller has provided an Alternate Source Notice for such period and Buyer is unable to use NOVA transportation otherwise available to it under Section15.3 through no fault of its own, thenSeller shall thereafter not be entitled to rely on the Alternate Source Notice in lieu of increasing the deliverability from Seller's Reserves, but shall thereupon immediately be obligated to cure the Deliverability Deficiency in accordance with Section 14.4.a.(i) and Section 14.11. 14.4.c. Seller shall be excused from its obligation to cure a Deliverability Deficiency pursuant to this Section 14.4, but only to the extent that the Deliverability Deficiency is not the result of Excess Third Party Sales, if: (a) The Determination provides Buyer with at least four (4) years advance notice that beginning with the fifth (5th) contract year following such current Determination, that deliverability from Seller's Reserves will be insufficient for Seller to meet its Maximum Daily Quantity delivery obligations to Buyer hereunder; and 32 Execution Copy (b) The Determination demonstrates that for a period of at least twelve (12) consecutive months the weighted average price of gas under this Contract is not greater than or equal to the price (the "Sufficient Acquisition Price") which would be necessary in order that additional gas supplies can be acquired and produced to cure the Deliverability Deficiency; and (c) Buyer does not agree within six (6) months of the Determination referred to in subsection (b) to increase the Price under the Contract for the Deliverability Deficiency to the Sufficient Acquisition Price effective from and after the first month of the Deliverability Deficiency. The Sufficient Acquisition Price shall, until a contrary Determination pursuant to Section 14.4.b, be deemed to be equal to the Price under this Contract. In the event that Seller intends to claim that the weighted average price of gas under this Contract is not greater than or equal to the Sufficient Acquisition Price, Seller shall instruct its independent reserve engineer to include as part of the Report which Seller proposes to be the basis of the Determination referred to in Section 14.4.b a full and true accounting which: (i) identifies the lands and reserves which are controlled by or could with reasonable diligence become controlled by Seller and used to supply the Contract (the "Available Lands"); and (ii) and provides Seller's least cost estimate (exclusive of any return on monies invested) to drill, develop, process and produce from each of the Available Lands in a manner which would cure a projected Deliverability Deficiency in whole or in part ("Net Development Costs"). For the purposes of estimating Net Development Costs, Seller's estimate of the cost to drill and develop the Available Lands included in such Net Development Costs for each of the Available Lands shall be reduced by 25%. Upon receipt of this 33 Execution Copy accounting and as part of such Report, Buyer and its agents shall be entitled to attend at the offices of Seller and examine all title documents relating to the Available Lands, historical information and any other data used by Seller to establish its Net Development Costs including the audited and unaudited accounting and record books of Seller, it being understood that Buyer shall keep such information as is requested by Seller confidential except as required for the purposes of this Contract. Following Buyer's audit, Buyer and Seller shall use reasonable efforts to agree to a Sufficient Acquisition Price failing which the matter shall be determined pursuant to arbitration invoked with respect to the Report in accordance with Section 14.2. The Arbitrator shall consider and determine the Sufficient Acquisition Price based on the costs, exclusive of any return on monies invested, of Seller developing the Available Lands to satisfy a Deliverability Deficiency, together with any evidence adduced by the parties and relevant to the determination. 14.5 In the event that Seller cures a Reserve Deficiency or a Deliverability Deficiency (each a "Deficiency") for any given year prior to the expiration of the respective cure periods provided in Sections 14.3 and 14.4 (each, a "Cure Period"), Seller shall provide Buyer immediate written notice thereof, to be confirmed within 60 days by an additional Determination. Once the Cure Period for any contract year for which the Determination projects a Deficiency begins to run, the length of such Cure Period shall not be altered by any subsequent Determination. 14.6 In each contract year that Seller issues a Report, Buyer shall be entitled to elect by written notice to Seller, to be made within forty-five (45) days of the receipt by Buyer of a Report in such contract year, to review the contracts and other documents and technical information that are relevant to such Report. Upon receiving such notice, and subject to Seller's reasonable needs to 34 Execution Copy maintain the confidentiality of any information, Seller shall permit Buyer, its agents and advisors to conduct such review, provided that such review shall be completed within forty-five (45) days of the date on which Seller has made available such relevant contracts and documents. 14.7 14.7.a In the event that the Maximum Daily Quantity is reduced under this Contract, Buyer may arrange a substitute supply of gas or other fuel supplies equal to all or part of the portion of the Maximum Daily Quantity which is reduced. 14.7.b. Buyer and Seller shall use their best efforts to secure all necessary regulatory approvals to implement delivery of any substitute gas supply by any third-party supplier or suppliers in the event the Maximum Daily Quantity is reduced for whatever reason pursuant to this Contract with the understanding that any provincial removal permit held by Seller and/or Buyer shall be sought to be utilized (by transfer, assignment or otherwise) as authorization of the removal and export by any third party supplier or suppliers of any substitute gas supplies. Buyer and Seller agree to use their best efforts to assist in accomplishing such transfer or assignment. 14.7.c. Upon notice by Buyer to Seller that Buyer has arranged for a substitute gas supply, Seller shall assign or otherwise-make available to each third party supplier a corresponding quantity of firm capacity on the facilities of NOVA or other intraprovincial pipeline and, to the extent permitted by NOVA or such other intraprovincial pipeline, Seller's rights under its contract with NOVA or such other intraprovincial pipeline to the extent of the substitute gas supplies to be supplied by each third-party supplier. 35 Execution Copy 14.8 In the event that the Maximum Daily Quantity is reduced pursuant to any provision of this Contract and Buyer obtains a substitute gas supply pursuant to Section 14.7 or other fuel supplies to operate Buyer's Plant, and provided that Seller's failure to cure the Deficiency is not excused pursuant to the provisions of Section 14.4, Seller shall indemnify Buyer for: (i) any and all costs and expenses reasonably incurred by Buyer in arranging, obtaining and using the substitute supply of gas or other fuel to the extent that such costs-and expenses exceed those which would have been incurred by Buyer had Seller delivered a quantity of gas equivalent to the substitute gas supply; and (ii) any demand charges incurred by Buyer pursuant to its transportation contracts with TCPL and United States Transporter(s) to the extent that transportation under such contracts is not utilized by Buyer; provided, however, that Seller's liability pursuant to this Section 14.8 shall not exceed an amount equal to the product of the amount of the reduction in the Maximum Daily Quantity and the sum of the demand charges per 103m3 or other applicable units of measurement incurred by Buyer pursuant to its transportation contracts with TCPL and United States Transporter(s). 14.9 14.9.a. Seller and Buyer agree that not more frequently than once every contract year, at such time as (i) Seller has a Minimum Removal Permit and (ii) Buyer has an NEB export license for the sum of 3,681 106m3 (130 Bcf) as at November 1, 1992, less the amount of gas which Seller is permitted to have produced from Seller's Lands as of the date of such removal pursuant to this Contract (i.e., Buyer's Daily Nomination plus Third Party Sales permitted pursuant to Section 13.5), and such NEB export license authorizes the sale and export from Canada of 424.9 103m3 (15,000 Mcf) per day for the unexpired term of this Contract, then Seller may remove from Seller's Lands as described in Exhibit A any lands not required to support any Canadian 36 Execution Copy regulatory authorizations or approvals required for the performance of this Contract, including, but not limited to, the NEB export license and the AEUB removal permit; provided, however, that there shall have been a Determination pursuant to Section 14.2 setting forth the information required pursuant to Section 14.9.b (in addition to any other information required to be included in a Determination); and provided, further, that the conditions of Sections 14.9.c and 14.9.d have been satisfied. 14.9.b. If Seller proposes to remove from Seller's Lands any lands as described in Section 14.9.a, there must first have been a Determination which, in addition to any other information required to be included in a Determination, (i) identifies the lands and reserves proposed to be removed pursuant to Section 14.9.a and the lands and reserves to remain dedicated to this Contract, (ii) establishes that deliverability from the remaining Seller's Reserves, tied-in and producing or in respect of which a letter of credit or letters of credit have been posted for the Tie-in Cost are sufficient for Seller to meet its Maximum Daily Quantity delivery obligations to Buyer hereunder for the then next five (5) full contract years of at least twelve (12) months; (iii) establishes that not less than 67% of the Seller's Reserves after the proposed removal are proven reserves and the remainder are probable reserves using NEB/AEUB standards; and (iv) demonstrates that Seller's Tie-in Cost for the remaining Seller's Reserves is not increased by the proposed removal. 14.9.c. No removal of lands pursuant to this Section 14.9 shall be permitted until (i) any letter(s) of credit required in connection with the applicable Determination shall have been posted, (ii) all regulatory approvals necessary for the removal of the proposed lands from this 37 Execution Copy Contract and from any existing permit required for the performance of this Contract, including, but not limited to, the NEB export license and the AEUB removal permit, shall have been received, and such necessary regulatory approvals shall not adversely affect any existing permit required for the performance of this Contract, including, but not limited to, the NEB export license and the AEUB removal permit and (iii) the Cure Gas Amount, if any, has been satisfied in accordance with Section 22.3. 14.9.d. Seller may not remove tied-in and producing Seller's Reserves pursuant to this Section 14.9 unless the remaining Seller's Reserves, tied-in and producing, are sufficient for Seller to maintain the Minimum Removal Permit. Buyer agrees to do such acts as are necessary to evidence Seller's removal of Lands completed in accordance with this Section 14.9. 14.10. In the event that, at any time, Buyer and Seller agree to remove lands from Seller's Lands and substitute additional different lands ("Reserve Substitution"), the parties shall use reasonable efforts to effect Reserve Substitution in a manner which provides Buyer with sufficient security that the Maximum Daily Quantity will be met for the remaining term of the Contract. In order to allow Buyer to assess a proposed substitution of reserves Seller shall provide Buyer with full information as may be requested by Buyer on the reserves to be added as a result of the Reserve Substitution. Buyer shall evaluate and determine whether the Reserve Substitution provides it with sufficient security of supply. In the event that Buyer and Seller cannot agree as to the Reserve Substitution the matter shall be determined by arbitration on the basis of providing Seller with the ability to produce up to the Maximum Daily Quantity from the Seller's Lands and 38 Execution Copy provide Buyer with assurance that the Maximum Daily Quantity shall be available for the remaining term of the Contract and on the basis that only lands of equivalent value will be substituted and, further, that seller's Reserves following any such Reserve substitution will meet the conditions of Sections 14.9.b.(ii)-(iv) (in each case, applying such conditions to the substitution rather than the removal of lands). Seller may not replace tied-in and producing Seller's Reserves pursuant to this Section 14.10 unless Seller's Reserves, tied-in and producing, following such Reserve Substitution, are sufficient to maintain the Minimum Removal Permit. Whether by agreement or by arbitration, the Reserve Substitution shall not take effect until both the AEUB and NEB have demonstrated to the satisfaction of Buyer that a removal permit and export license as required under this Contract shall remain in full force and effect notwithstanding the Reserve Substitution. Buyer agrees to do such acts as are necessary to evidence a Reserve Substitution completed in accordance with this Section 14.10. 14.11. 14.11.a. If a Report indicates a Deliverability Deficiency and Seller has not provided an Alternate Source Notice continuing in effect for the period covered by the Report or is not excused from its obligation to cure the Deliverability Deficiency pursuant to Section 14.4, Seller shall supply to Buyer an irrevocable letter of credit, with a term of not less than one calendar year, substantially in the form attached hereto as Exhibit D or otherwise satisfactory to Buyer. The letter of credit shall be transferable to the Collateral Agent or other agent of the bondholders under Buyer's Trust Indenture dated as of May 1, 1994, as amended from time to time. Buyer and Seller shall promptly take the necessary and appropriate actions to transfer to such agent any letter of 39 Execution Copy credit outstanding on the Effective Date which does not on its face provide for transfer to such agent. The letter of credit shall be issued by a financial institution whose long-term unsecured debt securities are rated A or better by Standard and Poor's Corporation or A or better by Dominion Bond Rating Service. Each letter of credit shall be in the amount of the Tie-in Cost (as set forth in the applicable Report) estimated by the independent reserve engineer for the additional lands and reserves necessary to cure the applicable Deliverability Deficiency; provided, however, that if Buyer does not accept such Report, the amount of the letter of credit shall be adjusted to equal the amount of the Tie-in Costs for the additional lands and reserves necessary to cure the Deliverability Deficiency as set forth in the Determination, which increase or decrease in the amount of the letter of credit shall be effected within ten business days of such Determination, unless Seller is not obligated to cure the Deliverability Deficiency pursuant to Section 14.4 with respect to the adjusted Tie-in Cost. Seller shall supply any required letter of credit within the later of (i) forty-five (45) days of delivery to Buyer of a Report and (ii) five (5) days of delivery to Seller of Buyer's response to such Report, unless Seller shall have sooner cured the applicable Deliverability Deficiency as evidenced by a Determination in accordance with Section 14.5. Seller agrees that (i) the posting of a letter of credit by the Seller in respect of a Deliverability Deficiency identified in a Report which is accepted by Buyer, and (ii) the adjustment by Seller of the amount of a posted letter of credit following a Determination in respect of the Tie-in Cost estimated by Seller in a Report which was not so accepted by Buyer shall in each case, but not otherwise, constitute Seller's conclusive acknowledgment that, with respect to the Deliverability Deficiency to which 40 Execution Copy the letter of credit relates, the Sufficient Acquisition Price for gas supplies and reserves required to cure such Deliverability Deficiency does not exceed the Price under this Contract. 14.1l.b. Buyer shall have the right to draw upon the letter of credit to indemnify itself to the extent of the costs, expenses and charges recoverable by Buyer pursuant to Section 14.8 ("Costs of Cover") if Seller has not cured the Deliverability Deficiency, as evidenced by a Determination in accordance with Section 14.5, required to be cured by the expiration of the Cure Period for such Deliverability Deficiency. Buyer shall promptly return to Seller any amounts drawn on said letter of credit in excess of the Costs of Cover. 14.1l.c. Not less than thirty (30) days prior to the expiration of such letter of credit, Seller shall provide Buyer with written evidence of the renewal of such letter of credit. If Seller does not renew such letter of credit, or if Seller fails to provide evidence of the renewal of such letter of credit by the time required pursuant to the preceding sentence, and Seller has not previously cured the relevant Deliverability Deficiency as evidenced by a Determination in accordance with Section 14.5, Buyer shall be entitled to draw the full amount of such letter of credit prior to its expiration and to apply the proceeds of such a drawing to its Costs of Cover. Buyer shall promptly return to Seller any amounts drawn under a letter of credit in excess of the Costs of Cover. 14.1l.d. Upon curing, in whole or in part, a Deliverability Deficiency, as evidenced by a Determination in accordance with Section 14.5, in respect of which a letter of credit has been posted, Seller shall be entitled, upon not less than ten business days' notice in writing to Buyer, to have the amount of the letter of credit reduced to the extent of the value of the cure so effected (if 41 Execution Copy such cure is partial only) and to withdraw the letter of credit, if the relevant Deliverability Deficiency has been completely cured. 14.12. Seller shall provide to Buyer monthly the information required by AEUB Form S-1, or any successor form, for the preceding month (the "Form S-1 Information") at the same time as Seller is required to provide such AEUB Form S-1 to the AEUB. If for any reason the AEUB ceases to require Seller to submit to the AEUB Form S-1 or any successor form, Seller shall nevertheless continue to provide to Buyer the Form S-1 Information by the fifteenth day of each month for the preceding month. If Seller does not provide Buyer with the Form S-1 Information when required, Buyer shall be entitled to take whatever actions are necessary to obtain such Form S-1 Information, including examining seller's original records upon which such Form S-1 Information is based if such Form S-1 Information is not publicly available from the AEUB in a timely fashion, and Seller shall reimburse Buyer for Buyer's costs and expenses in obtaining such Form S-1 Information. 14.13 Buyer shall provide to Seller, within thirty (30) days of Seller's written request, a written estimate of the number of hours which Buyer anticipates that the Plant will be dispatched on-line for the next following contract year.

If Seller fails to deliver the Daily Nomination pursuant to Article 5 hereof and is not otherwise excused from the obligation to deliver thereunder or under any other term of this Contract, including force majeure, Seller agrees, insofar as may be permitted under Seller's firm transportation service contract with NOVA (the "NOVA Contract") and subject to the terms and conditions thereof and the receipt of all necessary approvals from Canadian Regulatory Authorities, to make available at Seller's cost, Seller's transportation rights under the NOVA Contract only for that portion of such transportation service from the Alberta Energy Company 43 Execution Copy Station "C" ("AECO-C") to Empress Stn.

Seller shall take such actions as Buyer may reasonably require to take service under the NOVA Contract as contemplated hereunder (including, e.g., nominating service thereunder as requested by Buyer). Seller covenants and agrees to maintain in effect a firm transportation service contract with NOVA for delivery of the Maximum Daily Quantity to the Delivery Point for the primary term of this Contract. ARTICLE 16. FORCE MAJEURE 16.1 Neither Buyer nor Seller shall be liable in damages to the other for any act, omission or circumstances occasioned by or in consequence of any event constituting force majeure and the obligations of Seller and Buyer then existing hereunder shall be excused during the period thereof to the extent affected by such event of force majeure.

A failure to settle or prevent any strike or other controversy with employees or with anyone purporting or seeking to represent employees shall not be considered to be a matter within the control of the party claiming excuse. Under no circumstances will lack of finances be construed to constitute force majeure. 16.2. Such causes or contingencies affecting the performance of this contract by either party, however, shall not relieve it of liability in the event of its concurring negligence or in the event of its failure to use due diligence to remedy the situation and remove the cause in an adequate manner and with all reasonable dispatch, nor shall causes or contingencies affecting the performance of this Contract relieve either party from its obligations to make payments of amounts then due hereunder nor shall such causes or contingencies relieve either party of liability unless such party shall give notice and full particulars of the same in writing or by telex to the other party as soon as possible after the occurrence relied on. 16.3.
