Irrespective of the face amount of the Revolving Note or Notes, the Lenders shall never have the obligation to Advance any amount or amounts in excess of the Revolving Commitment or to increase the Revolving Commitment.

(b) Procedure for Borrowing. Whenever the Borrower desires an Advance under the Revolving Commitment, it shall give Agent telegraphic, telex, facsimile or telephonic notice ("Notice of Borrowing") of such requested Advance, which in the case of telephonic notice, shall be promptly

Upon receipt of such Notice of Borrowing, Agent shall advise each Lender thereof; provided, that if the Lenders have received at least one (1) day's notice of such Advance prior to funding of a Prime Rate Loan, or at least three (3) days' notice of each Advance prior to funding in the case of a BA Rate Loan, each Lender shall provide Agent at its office at BCE Place, ▇▇▇ ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇ M5J 2SI, not later than 1:00 p.m., Toronto, Canada time, on the Borrowing Date, in immediately available funds, its Pro Rata Part of the requested Advance, but the aggregate of all such fundings by each Lender shall never exceed such Lender's Commitment.

Upon funding of Advances by Lenders and such funds being made available to Borrower in accordance with this Agreement, pursuant to any such Notice of Borrowing, the Borrower shall have effected Advances hereunder.

(c) Voluntary Reduction of Revolving Commitment. Subject to the provisions of Section 5(e) hereof, the Borrower may at any time, or from time to time, upon not less than three (3) Business Days' prior written notice to Agent, reduce or terminate the Revolving Commitment; provided, however, that (i) each reduction in the Revolving Commitment must be in the amount of C$1,000,000 or more, in increments of C$1,000,000 and (ii) each reduction must be accompanied by a prepayment of the Notes in the amount by which the outstanding principal balance of the Notes exceeds the Revolving Commitment as reduced pursuant to this Section 2.

No Lender shall be required to lend hereunder any amount in excess of its legal lending limit.

(f) Type and Number of Advances. Any Advance on the Commitment may be a Prime Rate Loan or a BA Rate Loan, or a combination thereof, as selected by the Borrower pursuant to Section 4 hereof. The total number of Tranches which may be outstanding at any time shall never exceed four (4).

Although the Revolving Notes may be dated as of the Effective Date, interest in respect thereof shall be payable only for the period during which the Loans evidenced thereby are outstanding and, although the stated amount of the Revolving Notes may be higher, the Revolving Notes shall be enforceable, with respect to Borrower's obligation to pay the principal amount thereof, only to the extent of the unpaid principal amount of the Revolving Loans. Irrespective of the face amount of the Revolving Notes, no Lender shall ever be obligated to advance on the Revolving Commitment any amount in excess of its Revolving Commitment Percentage then in effect.

(b) Issuance of Additional Notes. At the Effective Date there shall be outstanding Revolving Notes in the aggregate face amount of C$250,000,000 payable to the order of Lenders. From time to time, new Notes may be issued to other Lenders as such Lenders become parties to this Agreement. Upon request from Agent, the Borrower shall execute and deliver to Agent any such new or additional Notes. From time to time, as new Notes are issued, the Agent shall require that each Lender exchange its Note(s) for newly issued Note(s) to accurately reflect the extent of each Lender's Commitment hereunder.

Any payment or prepayment received by Agent at any time after 12:00 noon, Toronto, Canada time on a Business Day shall be deemed to have been received on the next Business Day. Interest shall cease to accrue on any principal as of the end of the day preceding the Business Day on which any such payment or prepayment is deemed hereunder to have been received by Agent. If Agent fails to transfer any principal amount to any Lender as provided above, then Agent shall promptly direct such principal amount by wire transfer to such Lender.

(g) Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, or otherwise) on account of the Loans, (including, without limitation, any set-off) which is in excess of its Pro Rata Part of payments on either of the Loans, as the case may be, obtained by all Lenders, such Lender shall purchase from the other Lenders such participation as shall be necessary to cause such purchasing Lender to share the excess payment pro rata with each of them; provided that, if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, the purchase shall be rescinded and the purchase price restored to the extent of the recovery. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 3(g) may, to the fullest extent permitted by law, exercise all of its rights of payment (including the right of offset) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

(h) Non-Receipt of Funds by the Agent. Unless the Agent shall have been notified by a Lender or the Borrower (the "Payor") prior to the date on which such Lender is to make payment to the Agent of the proceeds of a Loan to be made by it hereunder or the Borrower is to make a payment to the Agent for the account of one or more of the Lenders, as the case may be (such payment being herein called the "Required Payment"), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, pay to the Agent the amount made available to it together with interest thereon in respect of the period commencing on the date such amount was made available by the Agent until the date the Agent recovers such amount at the rate applicable to such portion of the applicable Loan.

Past due principal and, to the extent permitted by law, past due interest shall bear interest, payable on demand, at a rate per annum equal to the Default Rate. Upon three (3) Business Days' written notice prior to the making by the Lenders of any BA Rate Loan (in the case of the initial Interest

Period therefor) or the expiration date of each succeeding Interest Period (in the case of subsequent Interest Periods therefor), Borrower shall have the option, subject to compliance by Borrower with all of the provisions of this Agreement, as long as no Event of Default exists, to specify whether the Interest Period commencing on any such date shall be a 30, 60 or 90 day period. If Agent shall not have received timely notice of a designation of such Interest Period as herein provided, Borrower shall be deemed to have elected to convert all maturing BA Rate Loans to Prime Rate Loans.

(b) Interest Rate Determination; Interest Act (Canada). The Agent shall determine each interest rate applicable to the Loans hereunder. The Agent shall give prompt notice to the Borrower and the Lenders of each rate of interest so determined and its determination thereof shall be conclusive absent error. For the purposes of the Interest Act (Canada) and disclosure thereunder, whenever any interest or any fee to be paid hereunder or in connection herewith is to be calculated on the basis of a year that is less than the actual number of days in the calendar year of calculation, the yearly rate of interest to which the rate used in such calculation is equivalent is the rate so used multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by 365, or if appropriate, 366. The rates of interest under this Agreement are nominal rates, and not effective rates or yields. The principle of deemed reinvestment of interest does not apply to any interest calculation under this Agreement.

(c) Conversion Option. Borrower may elect from time to time (i) to convert all or any part of its BA Rate Loans to Prime Rate Loans by giving Agent irrevocable notice of such election in writing prior to 10:00 a.m. (Toronto, Canada time) on the conversion date and such conversion shall be made on the requested conversion date, provided that any such conversion of BA Rate Loan shall only be made on the last day of the Interest Period with respect thereof, or (ii) to convert all or any part of its Prime Rate Loans to BA Rate Loans by giving the Agent irrevocable written notice of such election three (3) Business Days prior to the proposed conversion date and such conversion shall be made on the requested conversion date or, if such requested conversion date is not a Business Day, on the next succeeding Business Day. Any such conversion shall not be deemed to be a prepayment of any of the Loans for purposes of this Agreement or the Notes.

(d) Recoupment. If at any time the applicable rate of interest selected pursuant to Subsection 4(a)(i) or 4(a)(ii) above shall exceed the Maximum Rate, thereby causing the interest on the Notes to be limited to the Maximum Rate, then any subsequent reduction in the interest rate so selected or subsequently selected shall not reduce the rate of interest on the Notes below the Maximum Rate until the total amount of interest accrued on the Notes equals the amount of interest which would have accrued on the Notes if the rate or rates selected pursuant to Subsection 4(a)(i) or 4(a)(ii), as the case may be, had at all times been in effect.

5. Special Provisions Relating to Loans.

(a) Unavailability of Funds or Inadequacy of Pricing. In the event that, in connection with any proposed BA Rate Loan, the Agent reasonably determines, which determination shall, absent manifest error, be final, conclusive and binding upon all parties, due to changes in circumstances since the date hereof, adequate and fair means do not exist for determining the BA Rate or such rate will not accurately reflect the costs to the Lenders of funding BA Rate Loans for such Interest Period, the Agent shall give notice of such determination to the Borrower and the Lenders, whereupon, until the Agent notifies the Borrower and the Lenders that the circumstances giving rise to such suspension no longer exist, the obligations of the Lenders to make, continue or convert Loans into BA Rate Loans shall be suspended, and all loans to Borrower shall be Prime Rate Loans during the period of suspension.

(b) Change in Laws. If at any time any new law or any change in existing laws or in the interpretation of any new or existing laws shall make it unlawful for any Lender to make or

continue to maintain or fund Loans hereunder, then such Lender shall promptly notify Borrower in writing and such Lender's obligation to make, continue or convert Loans into BA Rate Loans under this Agreement shall be suspended until it is no longer unlawful for such Lender to make or maintain BA Rate Loans. Upon receipt of such notice, Borrower shall either repay the outstanding BA Rate Loans owed to such Lender, without penalty, on the last day of the current Interest Periods (or, if any Lender may not lawfully continue to maintain and fund such BA Rate Loans, immediately), or Borrower may convert such BA Rate Loans at such appropriate time to Prime Rate Loans.

(i) If, after the Effective Date, the adoption of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender with any request or directive (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency:

(A) shall subject such Lender to any Tax, duty, or other charge with respect to any BA Rate Loan, its Notes, or its obligation to make BA Rate Loans, or change the basis of taxation of any amounts payable to such Lender under this Agreement or its Notes in respect of any BA Rate Loan (other than franchise taxes and Taxes imposed on or measured by the overall net income of such Lender);

(B) shall impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Lender, including the Commitment of such Lender hereunder; or

(C) shall impose on such Lender any other condition affecting this Agreement or its Notes or any of such extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender of making, converting into, continuing, or maintaining any BA Rate Loan or to reduce any sum received or receivable by such Lender under this Agreement or its Notes with respect to any BA Rate Loan, then Borrower shall pay to such Lender on demand such amount or amounts as will reasonably compensate such Lender for such increased cost or reduction. If any Lender requests compensation by Borrower under this Section 5(c), Borrower may, by notice to such Lender (with a copy to Agent), suspend the obligation of such Lender to make or continue BA Rate Loans, or to convert all or part of the Prime Rate Loans owing to such Lender to BA Rate Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 5(c) shall be applicable); provided that such suspension shall not affect the right of such Lender to receive the compensation so requested.

(ii) If, after the Effective Date, any Lender shall have determined that the adoption of any applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender's obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then from

time to time upon demand Borrower shall pay to such Lender such additional amount or amounts as will reasonably compensate such Lender for such reduction.

(iii) Each Lender shall promptly notify Borrower and Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section 5(c) and will designate an alternative Lending Installation, if applicable, if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to it. Any Lender claiming compensation under this Section 5(c) shall furnish to Borrower and Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

(iv) Any Lender giving notice to the Borrower through the Agent pursuant to this Section 5(c) shall give to the Borrower a statement signed by an officer of such Lender setting forth in reasonable detail the basis for, and the calculation of such additional cost, reduced payments or capital requirements, as the case may be, and the additional amounts required to compensate such Lender therefor.

(v) Within five (5) Business Days after receipt by the Borrower of any notice referred to in this Section 5(c), the Borrower shall pay to the Agent for the account of the Lender issuing such notice such additional amounts as are required to compensate such Lender for the increased cost, reduced payments or increased capital requirements identified therein, as the case may be.

(d) Discretion of Lender as to Manner of Funding. Notwithstanding any provisions of this Agreement to the contrary, each Lender shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Lender had actually funded and maintained each BA Rate Loan through the purchase of deposits having a maturity corresponding to the last day of the Interest Period applicable to such BA Rate Loan and bearing an interest rate to the applicable interest rate for such Interest Period.

(e) Breakage Fees. Without duplication under any other provision hereof, if any Lender incurs any loss, cost or expense including, without limitation, any loss of profit and loss, cost, expense or premium reasonably incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Lender to fund or maintain any BA Rate Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to the Lenders as a result of any of the following events other than any such occurrence as a result in the change of circumstances described in Sections 5(a) and (b):

(i) any payment, prepayment or conversion of a BA Rate Loan on a date other than the last day of its Interest Period (whether by acceleration, prepayment or otherwise);

(ii) any failure to make a principal payment of a BA Rate Loan on the due date thereof; or

(iii) any failure by the Borrower to borrow, continue, prepay or convert to a BA Rate Loan on the dates specified in a notice given pursuant to Section 2(b) or 4(c) hereof;

then the Borrower shall pay to such Lender such amount as will reimburse such Lender for such loss, cost or expense. If any Lender makes such a claim for compensation, it shall furnish to Borrower and Agent a statement setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss,

cost or expense) and the amounts shown on such statement shall be conclusive and binding absent manifest error.

(f) Indemnified Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes from such payments, then (i) the sum payable shall be increased as necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 5(f)), the Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deduction been made, (ii) the Borrower shall make such deduction, and (iii) the Borrower shall pay the full amount deducted to the relevant governmental authority in accordance with applicable law, and (iv) the Borrower shall provide original evidence of any such payment of Indemnified Taxes to the Agent. In addition to the payments by the Borrower required by the previous sentence, the Borrower shall pay any and all present or future stamp or documentary Taxes or any other excise or property Taxes, charges or similar levies arising from any payment made hereunder or from the execution, delivery or enforcement of, or otherwise with respect to, this Agreement to the relevant governmental authority in accordance with applicable law. "Indemnified Taxes" means all Taxes other than Excluded Taxes. "Taxes" means all taxes, charges, fees, levies, imposts and other assessments, including all income, sales, use, goods and services, value added, capital, capital gains, alternative, net worth, transfer, profits, withholding, payroll, employer health, excise, real property and personal property taxes, and any other taxes, customs duties, fees, assessments or similar charges in the nature of a tax, together with any installments with respect thereto, and any interest, fines and penalties with respect thereto, imposed by any governmental authority, and whether disputed or not. "Excluded Taxes" means, with respect to the Agent, any Lender or any other recipient of any payment to be made by or on account of any obligation of the Borrower hereunder, any Taxes imposed pursuant to Part XIII of the Income Tax Act (Canada) (the "ITA") as a result of any Lender not being a resident of Canada for the purposes of the ITA, income Taxes imposed on (or measured by) its taxable income or capital Taxes imposed on (or measured by) its taxable capital, in each case by Canada, or by the jurisdiction under the laws of which such recipient is organized or in which its principal office is located.

(g) Replacement of Lenders. If any Lender suspends its obligations to make BA Loans pursuant to Section 5(b) or requests compensation under Section 5(c), then Borrower, with the consent of the Agent, shall have the right to remove or replace such Lender as a party to this Agreement, Borrower may, upon notice to such Lender and Agent and with the consent of the Agent, (i) remove such Lender by terminating such Lender's Revolving Commitment, or (ii) replace such Lender by causing such Lender to assign its Revolving Commitment (without payment of any assignment fee) pursuant to Section 28 to one or more other Lenders or Approved Funds procured by Borrower and approved by Agent. Borrower shall pay in full all principal, interest, fees, and other amounts owing to such Lender through the date of termination or assignment. Any Lender being replaced shall execute and deliver an Assignment and Acceptance with respect to such Lender's Revolving Commitment and outstanding Loans.

6. Collateral Security. To secure the payment and performance by Borrower of its indebtedness, liabilities, and obligations hereunder, and under the Notes and Security Instruments, whether now or hereafter incurred, matured or unmatured, direct or contingent, joint or several, or joint and several, including extensions, modifications, renewals and increases thereof, and substitutions therefor, Borrower has heretofore granted and assigned, and shall hereafter grant and assign, to Agent, for the ratable benefit of the Lenders, a Lien on certain of its Oil and Gas Properties, certain related equipment, oil and gas inventory and proceeds of the foregoing. To secure the performance of the Subsidiary Guarantors under the Subsidiary Guaranties, whether now or hereafter incurred, matured or

unmatured, direct or contingent, joint or several, or joint and several, including, extensions, modifications, renewals and increases thereof, and substitutions therefor, the Subsidiary Guarantors shall hereafter grant and assign to Agent, for the ratable benefit of the Lenders, a Lien on certain of their Oil and Gas Properties, certain related equipment, oil and gas inventory and the proceeds of the foregoing and a first and prior Lien on all of the issued and outstanding Capital Stock of their respective Subsidiaries that are Subsidiary Guarantors. To further secure the performance by the Borrower hereunder, the Borrower has heretofore granted, and shall hereafter grant, to the Agent, for the ratable benefit of the Lenders, a first and prior Lien on all of the issued and outstanding Capital Stock of each of its Material Subsidiaries. The Oil and Gas Properties heretofore and hereafter mortgaged to the Agent by the Borrower and the Subsidiary Guarantors shall represent not less than 90% of the Engineered Value (as hereinafter defined) of Borrower's and the Subsidiary Guarantors' Oil and Gas Properties, taken as a whole. In addition to the mortgaging of the Oil and Gas Properties, Borrower shall hereafter provide the Lenders with a Subsidiary Guaranty from each of its Material Subsidiaries. Obligations arising from agreements arising from Rate Management Transactions between Borrower or any Subsidiary Guarantor and one or more of the Lenders or an Affiliate of any of the Lenders shall be secured by the Collateral (as hereinafter defined) on a pari passu basis with the indebtedness and obligations of the Borrower under the Loan Documents. All Oil and Gas Properties and other assets, properties or interests in which Borrower or any Subsidiary Guarantor has or may hereafter grant to Agent, for the ratable benefit of the Lenders, a first and prior Lien (to the satisfaction of the Agent) in accordance with this Section 6, including the Oil and Gas Properties, as such assets, properties and interests are from time to time constituted, are hereinafter collectively called the "Collateral".

The granting and assigning of such security interests and Liens by Borrower and one or more of the Subsidiary Guarantors shall be pursuant to Security Instruments in form and substance reasonably satisfactory to the Agent. Concurrently with the delivery of each of the Security Instruments or within a reasonable time thereafter, Borrower and the Subsidiary Guarantors shall have furnished to the Agent mortgage and title opinions and other title information reasonably satisfactory to Agent with respect to the title and Lien status of Borrower's and Subsidiary Guarantors' interests in not less than 80% of the Engineered Value of the Oil and Gas Properties. "Engineered Value" for this purpose shall mean future net revenues discounted at the discount rate being used by the Agent as of the date of any such determination utilizing the pricing parameters used in the engineering report furnished to the Agent, pursuant to Sections 7 and 12 hereof. Borrower will, and will cause the Subsidiary Guarantors to, execute and deliver to the Agent, in the future, additional Security Instruments if the Agent reasonably deems such are necessary to insure perfection or maintenance of Lenders' security interests and Liens in the Oil and Gas Properties or any part thereof.

7. Borrowing Base.

(a) Borrowing Base. At the Effective Date, the Borrowing Base shall be C$138,022,500.00.

(b) Subsequent Determinations of the Borrowing Base. Subsequent determinations of the Borrowing Base shall be made by the Lenders semi-annually on May 1 and November 1 of each year beginning May 1, 2004 or as Unscheduled Redeterminations. By March 1 each year, beginning March 1, 2004, Borrower shall furnish to the Lenders an engineering report in form and substance reasonably satisfactory to Agent prepared by an independent petroleum engineering firm acceptable to Agent, said engineering report to utilize economic and pricing parameters used by the Agent as established from time to time, together with such other information, reports and data concerning the value, in Canadian Dollars, of the Oil and Gas Properties as Agent shall deem reasonably necessary to determine the value, in Canadian Dollars, of such Oil and Gas Properties. By September 1 of each year beginning September 1, 2004, or within thirty (30) days after either (i) receipt of notice from Agent that the Lenders require an Unscheduled Redetermination, or (ii) the Borrower gives notice to Agent of its desire to have an Unscheduled Redetermination

performed, the Borrower shall furnish to the Lenders an engineering report in form and substance reasonably satisfactory to Agent, said engineering report to utilize economic and pricing parameters used by the Agent as established from to time, together with such other information, reports and data concerning the value of such Oil and Gas Properties. Agent shall by written notice to the Borrower no later than May 1 and November 1 of each year, or within a reasonable time thereafter (herein called the "Determination Date"), notify the Borrower of the designation by the Lenders of the new Borrowing Base and for the period beginning on such Determination Date and continuing until, but not including, the next Determination Date. If an Unscheduled Redetermination is to be made by the Lenders, the Agent shall notify the Borrower within a reasonable time after receipt of all requested information of the new Borrowing Base, and such new Borrowing Base shall continue until the next Determination Date. If the Borrower does not furnish all such information, reports and data by any date specified in this Section 7(b), unless such failure is not the fault of the Borrower, the Lenders may nonetheless designate the Borrowing Base at any amounts, in Canadian Dollars, which the Lenders in their reasonable discretion determine and may redesignate the Borrowing Base from time to time thereafter until the Lenders receive all such information, reports and data, whereupon the Lenders shall designate a new Borrowing Base, as described above. The procedure for determining the Borrowing Base at each redetermination shall be that the Borrower shall submit to the Agent and Lenders, in writing, a proposed amount as the Borrowing Base as of the next redetermination date. Increases in the Borrowing Base will require approval of all Lenders, but other changes in the Borrowing Base will be subject to the approval of Majority Lenders. If any redetermined Borrowing Base is not approved by Majority Lenders within twenty (20) days after the submission to the Agent and the Lenders by the Borrower of the proposed amount, the Agent shall notify each of the Lenders that the proposed Borrowing Base has not been approved and each Lender will submit within ten (10) days thereafter its proposed Borrowing Base. The redetermined Borrowing Base shall be then determined based upon the weighted arithmetic average of the proposed amounts, in Canadian Dollars, submitted by each Lender, said proposals to be weighted according to each Lender's Commitment. Each Lender shall determine the amount, in Canadian Dollars, of the Borrowing Base based upon the loan collateral value which such Lender in its sole discretion (using such methodology, assumptions and discount rates as such Lender customarily uses in assigning collateral value to oil and gas properties, oil and gas gathering systems, gas processing and plant operations) assigns to such Oil and Gas Properties of the Borrower and the Subsidiary Guarantors at the time in question and based upon such other credit factors consistently applied (including, without limitation, the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Borrower and its Subsidiaries) as such Lender customarily considers in evaluating similar oil and gas credits. The Borrowing Base shall be reduced from time to time pursuant to the provisions of Section 2(d) hereof. It is expressly understood that the Lenders have no obligation to designate the Borrowing Base at any particular amounts, except in the exercise of their discretion, whether in relation to the Commitment or otherwise; provided, however, that the Lenders shall not have the obligation to designate a Borrowing Base in an amount in excess of the Revolving Commitment.

8. Fees.

(a) Unused Commitment Fee. The Borrower shall pay to Agent, for the ratable benefit of the Lenders, an unused commitment fee (the "Unused Commitment Fee") equivalent to the Applicable Margin times the daily average of the amount by which (i) the Revolving Commitment exceeds (ii) the Total Outstandings. Such Unused Commitment Fee shall be calculated on the basis of a year consisting of 360 days. The Unused Commitment Fee shall be payable in arrears on the last Business Day of each calendar quarter beginning March 31, 2004 with the final fee payment due on the Revolving Maturity Date for any period then ending for which the Unused Commitment Fee shall not have been theretofore paid. In the event the Revolving Commitment

terminates on any date prior to the end of any such quarterly period, the Borrower shall pay to the Agent, for the ratable benefit of the Lenders, on the date of such termination, the total Unused Commitment Fee due for the period in which such termination occurs.

(b) Borrowing Base Increase Fee. The Borrower shall pay to the Agent, for the ratable benefit of the Lenders, a Borrowing Base increase fee in an amount to be agreed upon by the Borrower, the Agent and the Majority Lenders as a condition to any increase in the Borrowing Base.

(c) Agency Fee. The Borrower shall pay to the Agent an annual agency fee for acting as administrative agent hereunder in an amount agreed upon between Agent and Borrower.

9. Prepayments.

(a) Voluntary Prepayments. Subject to the provisions of Section 5(e) hereof, the Borrower may at any time and from time to time, without penalty or premium, prepay the Notes, in whole or in part. Each such prepayment (i) on BA Rate Loans shall be made on at least three (3) Business Days' prior written notice to Agent, in a minimum amount of C$1,000,000 or any integral multiple of C$1,000,000 in excess thereof (or the unpaid balance of the Notes, whichever is less), plus accrued interest thereon to the date of prepayment and (ii) on Prime Rate Loans shall be made on written notice to Agent in a minimum amount of C$1,000,000 or any integral multiple of C$1,000,000 in excess thereof (or the unpaid balance on the Notes, whichever is less), plus accrued interest thereon to the date of prepayment.

(b) Mandatory Prepayment For Borrowing Base Deficiency. In the event the Total Outstandings ever exceed the Borrowing Base as determined by Lenders pursuant to Section 7(b) hereof (a "Borrowing Base Deficiency"), the Borrower shall, within ten (10) days after written notification from the Agent, either (A) by instruments reasonably satisfactory in form and substance to the Agent, provide the Agent with Collateral with value and quality in amounts satisfactory to all of the Lenders in their discretion in order to increase the Borrowing Base by an amount at least equal to such excess, or (B) prepay, without premium or penalty, the principal amount of the Notes in an amount at least equal to such excess plus accrued interest thereon to the date of prepayment, or (C) prepay, without premium or penalty, the principal amount of such excess in not more than six (6) equal monthly installments to be applied to principal plus accrued interest thereon with the first such monthly payment being due upon the 30th day after receipt of notice of such deficiency; provided that, the entire principal amount of such excess must be repaid before the next Determination Date. If the Total Outstandings ever exceed the Revolving Commitment or the Borrowing Base as a result of a required reduction in the Revolving Commitment or the Borrowing Base pursuant to Section 2(d) hereof, then in such event, Borrower shall, upon written notice, immediately prepay the principal amount of the Notes in an amount at least equal to such excess plus accrued interest to the date of prepayment.

10. Representations and Warranties. In order to induce the Lenders to enter into this Agreement, the Borrower represents and warrants to the Lenders (which representations and warranties will survive the delivery of the Notes) that:

(a) Creation and Existence. Borrower is a corporation duly amalgamated and validly existing under the laws of Alberta and is duly qualified in all jurisdictions wherein failure to qualify may result in a Material Adverse Effect. Each Guarantor is a corporation, partnership or limited liability company duly and properly incorporated or organized, and validly existing and in good standing under the laws of its jurisdiction of incorporation or organization and is duly qualified in all jurisdictions wherein failure to qualify may result in a Material Adverse Effect.

(k) Defaults. Neither Borrower nor any Guarantor is in default and no event or circumstance has occurred which, but for the passage of time or the giving of notice, or both, would constitute a default under any loan or credit agreement, indenture, mortgage, deed of trust, security agreement or other agreement or instrument to which Borrower or any Guarantor is a party in any respect that would be reasonably expected to have a Material Adverse Effect. No Event of Default hereunder has occurred and is continuing.

Such accounts shall be maintained with the Agent until all amounts due hereunder and under the Notes have been paid in full. To the extent not already so instructed, Borrower, and each Subsidiary Guarantor shall, within sixty (60) days of the Effective Date instruct and cause all monetary proceeds of production from the Oil and Gas Properties to be remitted to its Operating Accounts.

(d) Default shall be made in the due observance or performance of any of the covenants or agreements of the Borrower or any Guarantor contained in any Loan Document, including this Agreement (excluding covenants contained in Section 13 of the Agreement for which there is no cure period), and such default shall continue for more than thirty (30) days after written notice from Agent is received by Borrower (which notice may be given by Agent and shall be given by Agent upon request of Majority Lender); or

(e) Default shall be made in the due observance or performance of the covenants of Borrower or any Guarantor contained in Section 13 of this Agreement; or

(f) Default shall be made in respect of any obligation for borrowed money in excess of C$6,500,000, other than the Notes, for which Borrower or any Guarantor is liable (directly, by assumption, as guarantor or otherwise), or any obligations secured by any mortgage, pledge or other consensual security interest with respect thereto, on any asset or property of Borrower or

any Guarantor or in respect of any agreement relating to any such obligations unless Borrower or such Guarantor is not liable for same (i.e., unless remedies or recourse for failure to pay such obligations is limited to foreclosure of the collateral security therefor), and if such default shall continue beyond the applicable grace period, if any; or

(g) Borrower or any Guarantor shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking an appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due, or shall take any corporate action authorizing the foregoing; or

(h) An involuntary case or other proceeding, shall be commenced against Borrower or any Guarantor seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of sixty (60) days; or an order for relief shall be entered against Borrower or any Guarantor under the federal bankruptcy laws as now or hereinafter in effect; or

(i) Any receiver, receiver manager or similar officer is appointed over the Borrower or a Guarantor or over all of substantially all of the property and assets of the Borrower or a Guarantor and such receiver, receiver manager or similar official is not removed or discharged within twenty (20) days of such appointment; provided however, such grace period shall cease to apply if the Borrower or such Guarantor consents to such appointment, fails to diligently object and contest the appointment with appropriate proceedings, or if such receiver, receiver manager or similar official is not effectively stayed from realizing on the property and assets of the Borrower or such Guarantor; or

(j) A final judgment or order for the payment of money in excess of C$3,250,000 (or judgments or orders aggregating in excess of C$3,250,000) shall be rendered against Borrower or any Guarantor and such judgments or orders shall continue unsatisfied and unstayed for a period of thirty (30) days; or

(k) In the event the Total Outstandings shall at any time exceed the Borrowing Base established for the Notes, and the Borrower shall fail to comply with the provisions of Section 9(b) hereof; or

(l) A Change of Control shall occur; or

(m) A "Change of Control" under and as defined in the Indenture shall occur; or

(n) An Event of Default (under and as defined in the U.S. Credit Agreement) shall occur.

Upon occurrence of any Event of Default specified in Sections 14(g), (h) or (i) hereof, the entire principal amount due under the Notes and all interest then accrued thereon, and any other liabilities of the Borrower hereunder, shall become automatically and immediately due and payable all without notice and without presentment, demand, protest, notice of protest or dishonor or any other notice of default of any kind, all of which are hereby expressly waived by the Borrower. Upon the occurrence of any other Event of Default, the Agent, upon request of Required Lenders, shall by written notice to the Borrower declare the principal of, and all interest then accrued on, the Notes and any other liabilities hereunder to be forthwith due and payable, whereupon the same shall forthwith become due and payable without presentment, demand, protest, notice of intent to accelerate, notice of acceleration

or other notice of any kind, all of which the Borrower hereby expressly waives, anything contained herein or in the Note to the contrary notwithstanding.

Upon the occurrence and during the continuance of any Event of Default, the Lenders are hereby authorized at any time and from time to time, without notice to the Borrower or any Guarantor (any such notice being expressly waived by the Borrower and the Guarantors), to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by any of the Lenders to or for the credit or the account of the Borrower or any Guarantor against any and all of the indebtedness of the Borrower under the Notes and the Loan Documents, including this Agreement, irrespective of whether or not the Lenders shall have made any demand under the Loan Documents, including this Agreement or the Notes and although such indebtedness may be unmatured. Any amount set-off by any of the Lenders shall be applied against the indebtedness owed the Lenders by the Borrower pursuant to this Agreement and the Notes. The Lenders agree promptly to notify the Borrower and the affected Guarantor after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Lender under this Section 14 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Lenders may have.

Notwithstanding the foregoing, after the occurrence of an Event of Default, the provisions of the Intercreditor Agreement shall apply with respect to the rights of the Agent and all Lenders under both this Agreement and the U.S. Credit Agreement.

15. The Agent and the Lenders.

(a) Appointment and Authorization. Each Lender hereby appoints Agent as its nominee and agent, in its name and on its behalf: (i) to act as nominee for and on behalf of such Lender in and under all Loan Documents; (ii) to arrange the means whereby the funds of Lenders are to be made available to the Borrower under the Loan Documents; (iii) to take such action as may be requested by any Lender under the Loan Documents (when such Lender is entitled to make such request under the Loan Documents); (iv) to receive all documents and items to be furnished to Lenders under the Loan Documents; (v) to be the secured party, mortgagee, beneficiary, and similar party in respect of, and to receive, as the case may be, any collateral for the benefit of Lenders; (vi) to execute, as agent, the Subordination Agreement and by such execution to bind each Lender to such Agreement; (vii) to promptly distribute to each Lender all material information, requests, documents and items received from the Borrower under the Loan Documents; (viii) to promptly distribute to each Lender such Lender's Pro Rata Part of each payment or prepayment (whether voluntary, as proceeds of insurance thereon, or otherwise) in accordance with the terms of the Loan Documents and (ix) to deliver to the appropriate Persons requests, demands, approvals and consents received from Lenders. Each Lender hereby authorizes Agent to take all actions and to exercise such powers under the Loan Documents as are specifically delegated to Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. With respect to its Commitment hereunder and the Notes issued to it, Agent and any successor Agent shall have the same rights under the Loan Documents as any other Lender and may exercise the same as though it were not the Agent; and the term "Lender" or "Lenders" shall, unless otherwise expressly indicated, include Agent and any successor Agent in its capacity as a Lender. Agent and any successor Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of and generally engage in any kind of business with the Borrower, and any Person which may do business with the Borrower, all as if Agent and any successor Agent was not Agent hereunder and without any duty to account therefor to the Lenders; provided that, if any payments in respect of any property (or the proceeds thereof) now or hereafter in the possession or control of Agent which may be or become security for the obligations of the Borrower arising under the Loan Documents by reason of the general description of indebtedness secured or of property contained in any other agreements, documents

or instruments related to any such other business shall be applied to reduction of the obligations of the Borrower arising under the Loan Documents, then each Lender shall be entitled to share in such application according to its Pro Rata Part thereof. Each Lender, upon request of any other Lender, shall disclose to all other Lenders all indebtedness and liabilities, direct and contingent, of the Borrower to such Lender as of the time of such request.

(b) Note Holders. From time to time as other Lenders become a party to this Agreement, Agent shall obtain execution by the Borrower of additional Notes in amounts representing the Commitment of each such new Lender, up to an aggregate face amount of all Notes not exceeding C$250,000,000 for the Revolving Commitment. The obligation of such Lender shall be governed by the provisions of this Agreement, including but not limited to, the obligations specified in Section 2 hereof. From time to time, Agent may require that the Lenders exchange their Notes for newly issued Notes to more accurately reflect the Commitment of the Lenders. Agent may treat the payee of any Note as the holder thereof until written notice of transfer has been filed with it, signed by such payee and in form satisfactory to Agent.

(c) Consultation with Counsel. Lenders agree that Agent may consult with legal counsel selected by Agent and shall not be liable for any action taken or suffered in good faith by it in accordance with the advice of such counsel. LENDERS ACKNOWLEDGE THAT GARDERE ▇▇▇▇▇ ▇▇▇▇▇▇ LLP AND FRASER ▇▇▇▇▇▇ CASGRAIN LLP ARE COUNSEL FOR BANK ONE, BOTH AS AGENT AND AS A LENDER, AND THAT SUCH FIRMS DO NOT REPRESENT ANY OF THE OTHER LENDERS IN CONNECTION WITH THIS TRANSACTION.

(d) Documents. Agent shall not be under a duty to examine or pass upon the validity, effectiveness, enforceability, genuineness or value of any of the Loan Documents or any other instrument or document furnished pursuant thereto or in connection therewith, and Agent shall be entitled to assume that the same are valid, effective, enforceable and genuine and what they purport to be.

(e) Resignation or Removal of Agent. Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by giving written notice thereof to Lenders and the Borrowers, and Agent may be removed at any time with or without cause by Majority Lenders. If no successor Agent has been so appointed by Majority Lenders (and approved by the Borrower) and has accepted such appointment within thirty (30) days after the retiring Agent's giving of notice of resignation or removal of the retiring Agent, then the retiring Agent may, on behalf of Lenders, appoint a successor Agent. Any successor Agent must be approved by Borrower, which approval will not be unreasonably withheld. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Agent, and the retiring Agent, as the case may be, shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation or removal hereunder as Agent, the provisions of this Section 15 shall continue in effect for its benefit in respect to any actions taken or omitted to be taken by it while it was acting as Agent. To be eligible to be an Agent hereunder the party serving, or to serve, in such capacity must own a Pro Rata Part of the Commitment equal to the level of Commitment required to be held by any Lender pursuant to Section 28 hereof. If at any time that an Event of Default is continuing for a period of 30 days and it is ascertained by the Agent, in its sole discretion, that the Agent (either directly or through one or more Affiliates) has a conflict of interest in acting as Agent under this Agreement, then the Agent shall promptly take appropriate steps, as determined by the Agent, to eliminate such conflict of interest.

(f) Responsibility of Agent. It is expressly understood and agreed that the obligations of Agent under the Loan Documents are only those expressly set forth in the Loan Documents as to each

and that Agent, shall be entitled to assume that no Default or Event of Default has occurred and is continuing, unless Agent has actual knowledge of such fact or has received notice from a Lender or the Borrower that such Lender or the Borrower considers that a Default or an Event of Default has occurred and is continuing and specifying the nature thereof. Neither Agent nor any of its directors, officers, attorneys or employees shall be liable for any action taken or omitted to be taken by them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Agent shall not incur liability under or in respect of any of the Loan Documents by acting upon any notice, consent, certificate, warranty or other paper or instrument believed by it to be genuine or authentic or to be signed by the proper party or parties, or with respect to anything which it may do or refrain from doing in the reasonable exercise of its judgment, or which may seem to it to be necessary or desirable. None of the Co-Documentation Agents, the Syndication Agent, the Arrangers nor the Sole Bookrunner shall have any responsibilities as an agent hereunder.

Agent shall not be responsible to Lenders for any of the Borrower's recitals, statements, representations or warranties contained in any of the Loan Documents, or in any certificate or other document referred to or provided for in, or received by any Lender under, the Loan Documents, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of or any of the Loan Documents or for any failure by the Borrower to perform any of its obligations hereunder or thereunder. Agent may employ agents and attorneys-in-fact and shall not be answerable, except as to money or securities received by it or its authorized agents, for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care.

The relationship between Agent and each Lender is only that of agent and principal and has no fiduciary aspects. Nothing in the Loan Documents or elsewhere shall be construed to impose on Agent any duties or responsibilities other than those for which express provision is therein made. In performing its duties and functions hereunder, Agent does not assume and shall not be deemed to have assumed, and hereby expressly disclaims, any obligation or responsibility toward or any relationship of agency or trust with or for the Borrower or any of its beneficiaries or other creditors. As to any matters not expressly provided for by the Loan Documents, Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of all Lenders and such instructions shall be binding upon all Lenders and all holders of the Notes; provided, however, that Agent shall not be required to take any action which is contrary to the Loan Documents or applicable law.

Agent shall have the right to exercise or refrain from exercising, without notice or liability to the Lenders, any and all rights afforded to Agent by the Loan Documents or which Agent may have as a matter of law; provided, however, Agent shall not (i) without the consent of Majority Lenders, take any other action with regard to amending the Loan Documents, waiving any default under the Loan Documents or taking any other action with respect to the Loan Documents. Provided further, however, that no amendment, waiver, or other action shall be effected pursuant to the preceding sentence without the consent of all Lenders which: (a) would increase the Borrowing Base, (b) would reduce any fees hereunder, or the principal of, or the interest on, any Lender's Note or Notes, (c) would postpone any date fixed for any payment of any fees hereunder, or any principal or interest of any Lender's Note or Notes, (d) would increase the aggregate Commitment or any Lender's individual Commitment hereunder or would materially alter Agent's obligations to any Lender hereunder, (e) would release Borrower from its obligation to pay any Lender's Note or Notes, (f) would change the definition of Majority Lenders or Required Lenders, (g) would waive any of the conditions precedent to the Effective Date, (h) would extend the Revolving Maturity Date, (i) would release and substitute any Collateral except for releases or substitutions of Collateral sold in compliance with the provisions of Subsection 13(a)(ii) hereof or (j) would amend this sentence or the previous sentence. Agent shall not

have liability to Lenders for failure or delay in exercising any right or power possessed by Agent pursuant to the Loan Documents or otherwise unless such failure or delay is caused by the gross negligence of the Agent, in which case only the Agent responsible for such gross negligence shall have liability therefor to the Lenders.

(g) Independent Investigation. Each Lender severally represents and warrants to Agent that it has made its own independent investigation and assessment of the financial condition and affairs of the Borrower in connection with the making and continuation of its participation hereunder and has not relied exclusively on any information provided to such Lender by Agent in connection herewith, and each Lender represents, warrants and undertakes to Agent that it shall continue to make its own independent appraisal of the credit worthiness of the Borrower while the Notes are outstanding or its Commitment hereunder are in force. Agent shall not be required to keep itself informed as to the performance or observance by the Borrower of this Agreement or any other document referred to or provided for herein or to inspect the properties or books of the Borrower. Other than as provided in this Agreement, Agent shall not have any duty, responsibility or liability to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower which may come into the possession of Agent.

(h) Indemnification. Lenders agree to indemnify Agent, ratably according to their respective Commitment on a Pro Rata basis, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any proper and reasonable kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by Agent under the Loan Documents, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent's gross negligence or willful misconduct. Each Lender shall be entitled to be reimbursed by the Agent for any amount such Lender paid to Agent under this Section 15(h) to the extent the Agent has been reimbursed for such payments by the Borrower or any other Person. THE PARTIES INTEND FOR THE PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT THE AGENT FROM THE CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF ITS OWN NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING OR CONCURRING CAUSE OF ANY SUCH LIABILITY.

(i) Benefit of Section 15. The agreements contained in this Section 15 are solely for the benefit of Agent and the Lenders and are not for the benefit of, or to be relied upon by, the Borrower, any affiliate of the Borrower or any other Person.

(j) Pro Rata Treatment. Subject to the provisions of this Agreement, each payment (including each prepayment) by the Borrower and each collection by Lenders (including offsets) on account of the principal of and interest on the Notes and fees provided for in this Agreement, that are payable by the Borrower, shall be made Pro Rata; provided, however, in the event that any Defaulting Lender shall have failed to make an Advance as contemplated under Section 3 hereof and Agent or another Lender or Lenders shall have made such Advance, payment received by Agent for the account of such Defaulting Lender or Lenders shall not be distributed to such Defaulting Lender or Lenders until such Advance or Advances shall have been repaid in full to the Lender or Lenders who funded such Advance or Advances.

(k) Assumption as to Payments. Except as specifically provided herein, unless Agent shall have received notice from the Borrower prior to the date on which any payment is due to Lenders hereunder that the Borrower will not make such payment in full, Agent may, but shall not be required to, assume that the Borrower has made such payment in full to Agent on such date and

Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to Agent, each Lender shall repay to Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to Agent, at the interest rate applicable to such portion of the Loan.

(l) Other Financings. Without limiting the rights to which any Lender otherwise is or may become entitled, such Lender shall have no interest, by virtue of this Agreement or the Loan Documents, in (a) any present or future loans from, letters of credit issued by, or leasing or other financial transactions by, any other Lender to, on behalf of, or with the Borrower (collectively referred to herein as "Other Financings") other than the obligations hereunder; (b) any present or future guarantees by or for the account of the Borrower which are not contemplated by the Loan Documents; (c) any present or future property taken as security for any such Other Financings; or (d) any property now or hereafter in the possession or control of any other Lender which may be or become security for the obligations of the Borrower arising under any loan document by reason of the general description of indebtedness secured or property contained in any other agreements, documents or instruments relating to any such Other Financings.

(m) Interests of Lenders. Nothing in this Agreement shall be construed to create a partnership or joint venture between Lenders for any purpose. Agent, Lenders and the Borrower recognize that the respective obligations of Lenders under the Commitment shall be several and not joint and that neither Agent nor any of Lenders shall be responsible or liable to perform any of the obligations of the other under this Agreement. Each Lender is deemed to be the owner of an undivided interest in and to all rights, titles, benefits and interests belonging and accruing to Agent under the Security Instruments, including, without limitation, liens and security interests in any collateral, fees and payments of principal and interest by the Borrower under the Commitment on a Pro Rata basis. Each Lender shall perform all duties and obligations of Lenders under this Agreement in the same proportion as its ownership interest in the Loans outstanding at the date of determination thereof.

(n) Investments. Whenever Agent in good faith determines that it is uncertain about how to distribute to Lenders any funds which it has received, or whenever Agent in good faith determines that there is any dispute among the Lenders about how such funds should be distributed, Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Agent is otherwise required to invest funds pending distribution to the Lenders, Agent may invest such funds pending distribution (at the risk of the Borrower). All interest on any such investment shall be distributed upon the distribution of such investment and in the same proportions and to the same Persons as such investment. All monies received by Agent for distribution to the Lenders (other than to the Person who is Agent in its separate capacity as a Lender) shall be held by the Agent pending such distribution solely as Agent for such Lenders, and Agent shall have no equitable title to any portion thereof.

16. Exercise of Rights. No failure to exercise, and no delay in exercising, on the part of the Agent or the Lenders, any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right. The rights of the Agent and the Lenders hereunder shall be in addition to all other rights provided by law.

17. Notices. Any notices or other communications required or permitted to be given by this Agreement or any other documents or instruments referred to herein must be given in writing (which may be by bank wire, telecopy or similar writing) and shall be given to the party to whom such notice or communication is directed at the address or telecopy number of such party as follows:

18. Expenses.

THE BORROWER HEREBY ACKNOWLEDGES THAT GARDERE ▇▇▇▇▇ ▇▇▇▇▇▇ LLP AND FRASER ▇▇▇▇▇▇ CASGRAIN LLP ARE SPECIAL COUNSEL TO BANK ONE, AS AGENT AND AS A LENDER, UNDER THIS AGREEMENT AND SUCH FIRMS ARE NOT COUNSEL TO, NOR DO SUCH FIRMS REPRESENT THE BORROWER IN CONNECTION WITH THE TRANSACTIONS DESCRIBED IN THIS AGREEMENT. The Borrower is relying on separate counsel in the transaction described herein. The Borrower shall indemnify the Lenders against any transfer Taxes, document Taxes, assessments or charges made by any governmental authority by reason of the execution, delivery and filing of the Loan Documents. The obligations of this Section 18 shall survive any termination of this Agreement, the expiration of the Loans and the payment of all indebtedness of the Borrower to the Lenders hereunder and under the Notes.

19. Indemnity. The Borrower agrees to indemnify and hold harmless Agent, the Lenders, the Arrangers, the Sole Bookrunner and their respective officers, employees, agents, attorneys and representatives (singularly, an "Indemnified Party", and collectively, the "Indemnified Parties") from and against any loss, cost, liability, damage or expense (including the reasonable fees and out-of-pocket expenses of counsel to the Indemnified Parties, including all local counsel hired by such counsel) ("Claim") incurred by the Indemnified Parties in investigating or preparing for, defending against, or providing evidence, producing documents or taking any other action in respect of any commenced or

threatened litigation, administrative proceeding or investigation under any federal or provincial securities law, federal, provincial or state environmental law, or any other statute of any jurisdiction, or any regulation, or at common law or otherwise, which is alleged to arise out of or is based upon any acts, practices or omissions or alleged acts, practices or omissions of the Borrower or its agents or arises in connection with the duties, obligations or performance of the Indemnified Parties in negotiating, preparing, executing, accepting, keeping, completing, countersigning, issuing, selling, delivering, releasing, assigning, handling, certifying, processing or receiving or taking any other action with respect to the Loan Documents and all documents, items and materials contemplated thereby even if any of the foregoing arises out of an Indemnified Party's ordinary negligence. The indemnity set forth herein shall be in addition to any other obligations or liabilities of the Borrower to the Lenders hereunder or at common law or otherwise, and shall survive any termination of this Agreement, the expiration of the Loans and the payment of all indebtedness of the Borrower to the Lenders hereunder and under the Notes, provided that the Borrower shall have no obligation under this Section to a Lender with respect to any of the foregoing arising out of the gross negligence or willful misconduct of any Lender. If any Claim is asserted against any Indemnified Party, the Indemnified Party shall endeavor to notify the Borrower of such Claim (but failure to do so shall not affect the indemnification herein made except to the extent of the actual harm caused by such failure). The Indemnified Party shall have the right to employ, at the Borrower's expense, counsel of the Indemnified Parties' choosing and to control the defense of the Claim. The Borrower may at its own expense also participate in the defense of any Claim. Each Indemnified Party may employ separate counsel in connection with any Claim to the extent such Indemnified Party believes it reasonably prudent to protect such Indemnified Party. THE PARTIES INTEND FOR THE PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT EACH INDEMNIFIED PARTY FROM THE CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF ITS OWN NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING, OR CONCURRING CAUSE OF ANY CLAIM.

20. Governing Law. THIS AGREEMENT IS BEING EXECUTED AND DELIVERED, AND IS INTENDED TO BE PERFORMED, IN THE PROVINCE OF ALBERTA, CANADA AND THE SUBSTANTIVE LAWS OF THE PROVINCE OF ALBERTA, CANADA SHALL GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT AND ALL OTHER DOCUMENTS AND INSTRUMENTS REFERRED TO HEREIN, UNLESS OTHERWISE SPECIFIED THEREIN.

21. Invalid Provisions. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future laws effective during the term of this Agreement, such provisions shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions of the Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement.

22. Maximum Interest Rate. If any provision of this Agreement would oblige the Borrower to make any payment of interest or other amount payable to any Lender in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by that Lender of "interest" at a "criminal rate" (as such terms are construed under the Criminal Code (Canada)), then, notwithstanding such provision, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by applicable law or so result in a receipt by that Lender of "interest" at a "criminal rate" ("Maximum Rate").

23. Amendments. This Agreement may be amended only by an instrument in writing executed by an authorized officer of the party against whom such amendment is sought to be enforced. No modification or waiver of any provision of the Loan Documents, including this Agreement, or the

Notes nor consent to departure therefrom, shall be effective unless in writing signed by Borrower and Majority Lenders (or by Agent on behalf of Majority Lenders) subject to the additional requirements of Section 15(f) hereof, to the extent applicable. No such consent or waiver shall extend beyond the particular case and purpose involved. No notice or demand given in any case shall constitute a waiver of the right to take other action in the same, similar or other circumstances without such notice or demand.

24. Multiple Counterparts. This Agreement may be executed in one or more counterparts and by different parties hereto in separate counterparts each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document. However, this Agreement shall bind no party until the Borrowers, Agent and Lenders have executed a counterpart. Facsimiles shall be effective as originals.

25. Conflict. In the event any term or provision hereof is inconsistent with or conflicts with any provision of the Loan Documents, the terms or provisions contained in this Agreement shall be controlling.

26. Survival. All covenants, agreements, undertakings, representations and warranties made in the Loan Documents, including this Agreement, the Notes or other documents and instruments referred to herein shall survive all closings hereunder and shall not be affected by any investigation made by any party.

27. Parties Bound. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors, assigns, heirs, legal representatives and estates, provided, however, that the Borrower may not, without the prior written consent of all of the Lenders, assign any rights, powers, duties or obligations hereunder.

28. Assignments and Participations.

(a) Permitted Purchasers and Minimum Amount. Any Lender may at any time assign to one or more banks or other entities ("Purchasers") all or any part of its rights and obligations under the Loan Documents. Such assignment shall be substantially in the form of Exhibit "F" or in such other form as may be agreed to by the parties thereto. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Loans of the assigning Lender or (unless the Borrower and the Agent otherwise consents) be in an aggregate amount not less than C$7,000,000. The amount of the assignment shall be based on the Commitment or outstanding Loans (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the "Trade Date," if the "Trade Date" is specified in the assignment.

(b) Consents. The consent of the Borrower shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund, provided that the consent of the Borrower shall not be required if a Default or Event of Default has occurred and is continuing. The consent of the Agent shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund. Any consent required under this Section 28(b) shall not be unreasonably withheld or delayed.

(c) Assignment. Upon (i) delivery to the Agent of an assignment, together with any consents required by Sections 28(a) and 28(b), and (ii) payment of a C$3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent or CSFB Toronto Branch is the assignor with respect to such assignment in which event such fee is deemed waived), such

assignment shall become effective on the effective date specified in such assignment. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to the Intercreditor Agreement, this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Loans assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an assignment covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the obligations and termination of the applicable agreement. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with Section 28(a), 28(b), 28(c) and 28(d) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 28(e). Upon the consummation of any assignment to a Purchaser pursuant to this Section 28(c), the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

(d) Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Toronto, Canada a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(e) Participations. Any Lender may at any time sell to one or more banks or other entities ("Participants") participating interests in any Loan owing such Lender, any Note held by such Lender, any Commitment of such Lender or any interest of such Lender under the Loan Documents hereunder to one or more pension plans, investment funds, insurance companies, financial institutions or other Persons, provided, that:

(i) each Lender shall retain the sole right to vote hereunder, and no Participant shall be entitled to vote hereunder on decisions requiring consent or approval of Lender, Majority Lenders or Required Lenders;

(ii) in the event of any such sale by a Lender of a participating interest to a Participant, such Lender's obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Loans and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interest and Agent and Borrower shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under the Loan Documents.

(iii) The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 14 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 14 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 14, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 14 as if each Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to the benefits of Section 5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 28(a), provided that a Participant shall not be entitled to receive any greater payment under Section 5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower.

(f) Information. The Borrower authorizes each Lender to disclose to any Participant or any other Person acquiring an interest in the Loan Documents by operation of law (each a "Transferee") and any prospective Transferee any and all information in such Lender's possession concerning the creditworthiness of the Borrower and its Subsidiaries, including without limitation any information contained in any reports; provided that each Transferee and prospective Transferee agrees to be bound by Section 29 of this Agreement.

29. Confidentiality. Agent and each Lender agrees to hold any confidential information which it may receive from the Borrower pursuant to this Agreement in confidence, except for disclosure (i) to its Affiliates and to other Lenders and their respective Affiliates, (ii) to legal counsel, accountants, and other professional advisors to Agent, such Lender or to an assignee, participant, or prospective assignee or participant, (iii) to regulatory officials, (iv) to any Person as requested pursuant to or as required by law, regulation, or legal process, (v) to any Person in connection with any legal proceeding to which Agent or such Lender is a party, (vi) to Agent's or such Lender's direct or indirect contractual counterparties in swap agreements or to legal counsel, accountants and other professional advisors to such counterparties, (vii) permitted by Section 28, and (viii) to rating agencies if requested or required by such agencies in connection with a rating relating to the Advances hereunder. Notwithstanding anything herein to the contrary, confidential information shall not include, and Agent and each Lender (and each employee, representative or other agent of Agent or any Lender) may disclose to any and all Persons, without limitation of any kind, the "tax treatment" and "tax structure" (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are or have been provided to Agent or such Lender relating to such tax treatment or tax structure; provided that with respect to any document or similar item that in either case contains information concerning such tax treatment or tax structure of the transactions contemplated hereby as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to such tax treatment or tax structure.

30. Choice of Forum: Consent to Service of Process and Jurisdiction. THE OBLIGATIONS OF BORROWER UNDER THE LOAN DOCUMENTS ARE PERFORMABLE IN THE PROVINCE OF ALBERTA, CANADA. ANY SUIT, ACTION OR PROCEEDING AGAINST THE BORROWER WITH RESPECT TO THE LOAN DOCUMENTS OR ANY JUDGMENT ENTERED BY ANY COURT IN RESPECT THEREOF, MAY BE BROUGHT IN ▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇, AND THE BORROWER HEREBY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS FOR THE PURPOSE OF ANY SUCH SUIT, ACTION OR PROCEEDING. THE BORROWER HEREBY IRREVOCABLY CONSENTS

TO SERVICE OF PROCESS IN ANY SUIT, ACTION OR PROCEEDING IN SAID COURT BY THE MAILING THEREOF BY LENDER BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE BORROWER, AT THE ADDRESS FOR NOTICES AS PROVIDED IN SECTION 17. THE BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT BROUGHT IN THE COURTS LOCATED IN THE PROVINCE OF ALBERTA, CANADA AND HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

31. Waiver of Jury Trial. THE BORROWER HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

32. Other Agreements. THIS WRITTEN CREDIT AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

33. Financial Terms. All accounting terms used in this Agreement which are not specifically defined herein shall be construed in accordance with GAAP.

34. Interpretation, etc. Any of the terms defined herein may, unless the context otherwise requires, be used in the singular or the plural, depending on the reference. References herein to any Section, Annex, Exhibit or Schedule shall be to a Section, Annex, Exhibit or Schedule, as the case may be, hereof unless otherwise specifically provided. The use herein of the word "include" or "including", when following any general statement, term or matter, shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to similar items or matters, whether or not nonlimiting language (such as "without limitation" or "but not limited to" or words of similar import) is used with reference thereto, but rather shall be deemed to refer to all other items or matters that fall within the broadest possible scope of such general statement, term or matter.

35. Original Credit Agreement. Effective upon the Effective Date, this Agreement shall supersede in its entirety the Original Credit Agreement; provided, however, that all loans, and other indebtedness, obligations and liabilities outstanding under the Original Credit Agreement on such date shall continue to constitute Loans, and other indebtedness, obligations and liabilities under this Agreement and the execution and delivery of this Agreement or any of the Loan Documents hereunder shall not constitute a novation, refinancing or any other fundamental change in the relationship among the parties and the Loans, and other indebtedness, obligations and liabilities outstanding hereunder, to the extent outstanding under the Original Credit Agreement immediately prior to the date hereof, shall constitute the same loans, and other indebtedness, obligations and liabilities as outstanding under the Original Credit Agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the day and year first above written.
