|(c) | The failure of a Party to take any steps in exercising any right in respect of the breach or nonfulfillment of any provision of any of the Loan Documents will not operate as a waiver of that right, breach or provision, nor will any single or partial exercise of any right preclude any other or future exercise of that right or the exercise of any other right, whether in Law or otherwise.

|    |                                                                                                                                                                                                                                                                                                                     
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(d) | Acceptance of payment by a Party after a breach or nonfulfillment of any provision of any of the Loan Documents requiring a payment to such Party will constitute a waiver of such provision if cured by such payment, but will not constitute a waiver or cure of any other provision of any of the Loan Documents.

|(a) | Except as otherwise expressly provided, all accounting terms, principles and calculations applicable to the Credit Facility will be interpreted, applied and calculated, as the case may be, in accordance with GAAP.

|    |    
|--- | ---
|(b) | If:

|    |                                                                               
|--- | ------------------------------------------------------------------------------
|(i) | there occurs a material change in generally accepted accounting principles; or

|---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(ii) | the Borrower or any of the Restricted Subsidiaries adopts a material change in an accounting policy in order to more appropriately present events or transactions in its financial statements;

and the above change would require disclosure under GAAP in the consolidated financial statements of the Borrower and would cause an amount required to be determined for the purposes of a financial covenant under Section 8.3 (a " Financial Covenant ") to be materially different than the amount that would be determined without giving effect to such change, the Borrower shall notify the Agent of such change (an " Accounting Change ").  Such notice (an " Accounting Change Notice ") shall describe the nature of the Accounting Change, its effect on the current and immediately prior year's financial statements in accordance with GAAP and state whether the Borrower desires to revise the method of calculating one or more of the Financial Covenants (including the revision of any of the defined terms used in the determination of such Financial Covenant) in order that amounts determined after giving effect to such Accounting Change and the revised method of calculating such Financial Covenant will approximate the amount that would be determined without giving effect to such Accounting Change and without giving effect to the revised method of calculating such Financial Covenant.  The Accounting Change Notice shall be delivered to the Agent  within 60 days of the end of the Fiscal Quarter in which the Accounting Change is implemented or, if such Accounting Change is implemented in the fourth Fiscal Quarter or in respect of an entire Fiscal Year, within 120 days of the end of such period.


|    |                                                                                                                                                                                                                                                                                                                                                                                                          
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(c) | If, pursuant to the Accounting Change Notice, the Borrower does not indicate that it desires to revise the method of calculating one or more of the Financial Covenants, the Majority Lenders may within 30 days of receipt of the Accounting Change Notice, notify the Borrower that they wish to revise the method of calculating one or more of the Financial Covenants in the manner described above.

|    |

|(d) | If either the Borrower or the Majority Lenders so indicate that they wish to revise the method of calculating one or more of the Financial Covenants, the Borrower and the Majority Lenders shall in good faith attempt to agree on a revised method of calculating the Financial Covenants.  If, however, within 30 days of the foregoing notice by the Borrower or the Majority Lenders of their desire to revise the method of calculating one or more of the Financial Covenants, the Borrower and the Majority Lenders have not reached agreement in writing on such revised method of calculation, such method of calculation shall not be revised and all amounts to be determined thereunder shall be determined without giving effect to the Accounting Change.  For greater certainty, if no notice of a desire to revise the method of calculating the Financial Covenants in respect of an Accounting Change is given by either the Borrower or the Majority Lenders within the applicable time period described above, the method of calculating the Financial Covenants shall not be revised in response to such Accounting Change and all amounts to be determined pursuant to the Financial Covenants shall be determined after giving effect to such Accounting Change.

|(e) | If a Compliance Certificate is delivered in respect of a Fiscal Quarter or Fiscal Year in which an Accounting Change is implemented without giving effect to any revised method of calculating any of the Financial Covenants, and subsequently, as provided above, the method of calculating one or more of the Financial Covenants is revised in response to such Accounting Change, or the amounts to be determined pursuant to any of the Financial Covenants are to be determined without giving effect to such Accounting Change, the Borrower shall deliver a revised Compliance Certificate.  Any Default or Event of Default which arises as a result of the Accounting Change and which is cured by this Section 1.9 shall be deemed to have never occurred.

|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(a) | Credit Facility.  Subject to the terms and conditions of this Agreement, each Lender hereby severally agrees to make available, until the  Maturity Date,  Advances in an aggregate amount up to its  Commitment (the "Credit Facility") and, as part of its  Commitment, the

Swing Line Lender hereby severally agrees to make available Swing Line Advances up to its Swing Line Commitment.


The Credit Facility is a revolving credit facility and, prior to the Maturity Date, the Borrower may (i) borrow, repay and re-borrow Prime Loans, USBR Loans, Overdrafts and LIBOR Loans, (ii) issue, repay and re-issue Bankers' Acceptances and (iii) issue, cancel and re-issue Letters of Credit.


|    |                                                                                           
|--- | ------------------------------------------------------------------------------------------
|(b) | Types of Advances.  The Borrower may obtain Advances under each Credit Facility by way of:

|    |

|(i) | Prime Loans;

|     |

|(ii) | USBR Loans;

|      |             
|----- | ------------
|(iii) | LIBOR Loans;

|     |                      
|---- | ---------------------
|(iv) | Bankers' Acceptances;

|    |                       
|--- | ----------------------
|(v) | Letters of Credit; and

|     |                                                   
|---- | --------------------------------------------------
|(vi) | Overdrafts (under the Swing Line Commitment only).

|    |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(c) | Several Obligations.  No Lender shall be responsible for the Commitments of any other Lender.  The failure of a Lender to make available its Pro Rata Share of any Advance in accordance with its obligations under this Agreement shall not release any other Lender from its obligations hereunder.  Notwithstanding anything to the contrary in this Agreement, no Lender shall be obligated to make Advances available to the Borrower in excess of its Commitments.  The obligation of each Lender to make its Commitments available to the Borrower is a separate obligation between that Lender and the Borrower and such obligation is not the joint or joint and several obligation of any other Lender.

2.2  Purpose of Credit Facility


All Drawdowns shall be used for lawful general corporate purposes of the Borrower.


2.3  Extension of Credit Facility

|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(a) | The Borrower may, at its option, by delivering to the Agent an Extension Request, request the Lenders to extend the Maturity Date for an additional period of one, two, three or four years;providedthat (i) this request cannot be made more than 90 days or less than 60 days before each Renewal Date and (ii) the new Maturity Date cannot extend for more than four years from the applicable Renewal Date.

|    |

|(b) | Promptly after receipt from the Borrower of an executed Extension Request, the Agent shall deliver to each Lender a copy of such request, and each Lender shall, within 30 days after receipt of such request, advise the Agent in writing (i) whether such Lender will agree to extend the Maturity Date, and (ii) if such Lender will agree to extend the Maturity Date, the amount, if any, by which such  Lender is prepared to increase its Commitments in the event the Borrower proposes to assign some or all of the Commitments of a Non-Extending Lender (as defined below);providedthat if any Lender fails to so advise the Agent within such 30 day period, then such  Lender shall be deemed to have advised the Agent that it will not agree to extend the Maturity Date.  The Agent shall promptly notify the Borrower if any Lender advises or is deemed to advise that it will not agree to extend the Maturity Date.  The Agent

30


---




shall only extend the Maturity Date upon the agreement of the Majority Lenders and such extension shall apply only to those Lenders which provided their consent to such extension (the " Extending Lenders ").  The determination of each Lender whether or not to extend the Maturity Date shall be made by each individual Lender in its sole discretion.


|    |                                                                                                                                                                          
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(c) | Promptly after all of the Lenders have advised, or are deemed to have advised, the Agent whether or not they will be extending the Maturity Date, the Agent shall either:

|    |                                                                                                 
|--- | ------------------------------------------------------------------------------------------------
|(i) | deliver to the Borrower (with a copy to each Lender) a written extension signed by the Agent; or

|     |                                                                    
|---- | -------------------------------------------------------------------
|(ii) | notify the Borrower that the request for extension has been denied.

If the extension is approved by less than all of the Lenders, then the Agent shall also advise the Borrower of which Lender(s) did not agree to the requested extension (each being a " Non-Extending Lender "), each Non-Extending Lender's Pro Rata Share of the Loan Indebtedness then outstanding and the amount, if any, by which each Extending Lender is prepared to increase its Commitments in the event the Borrower proposes to assign some or all of the Commitments of a Non-Extending Lender.


|    |                                                                                                                                                                                                                                            
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(d) | The failure of the Agent to deliver a written extension or to notify the Borrower of the denial of the request for extension by the Maturity Date, shall be deemed to be notification by the Agent of the denial of the Borrower's request.

|    |                                                                                                                                                                  
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------
|(e) | Upon the delivery to the Borrower of a written extension, the Maturity Date shall be extended for one, two or three years as specified in such written extension.

|    |

|(f) | If an Extension Request is approved but there are Non-Extending Lenders, then:

|(i) | the Borrower may at any time (subject to Sections 13.2(d), 13.2(e) and 15.1(e)) require any Non-Extending Lender to assign all or any part of its rights, benefits and interests under its Commitments and its Pro Rata Shares of all Loan Indebtedness then outstanding under the Credit Facility (collectively, the "Assigned Interests") to (A) any Extending Lenders which have agreed to increase their Commitments and purchase Assigned Interests, and (B) to the extent the Assigned Interests are not transferred to Extending Lenders, assignees selected by the Borrower and acceptable to the Agent and the LC Issuer, each acting reasonably;providedthat any partial assignment may only occur if the remaining Commitments of such Non-Extending Lender are cancelled in accordance with paragraph (ii) below.  Such assignments shall be effective upon execution of Lender Assignment Agreements, upon payment to the relevant Non-Extending Lender (in immediately available funds) by the relevant assignee of an amount equal to its Pro Rata Shares of all Loan Indebtedness being assigned, upon execution of an intercreditor agreement if requested by such Non-Extending Lender pursuant to Section 10.3 (but only if such Non-Extending Lender or its Affiliate is a Swap Lender) and upon payment by the relevant assignee to the Agent (for the Agent's own account) of the transfer fee contemplated in Section 15.1(b).  Upon such assignment and transfer, the Non-Extending Lender shall have no further right, interest or obligation in respect of the Assigned Interests and the assignee thereof shall succeed to the position of such Lender as if the same was an original party hereto in the place and stead of such Non-Extending Lender; and

The Borrower shall repay in full all Outstandings and all other Loan Indebtedness owed to Non-Extending Lenders on the Maturity Date determined without regard to the extension agreed to by the Extending Lenders.

|(a) | Availability.  Notwithstanding Sections 2.4, 2.7(c) and 2.8 but otherwise subject to the limits and conditions referred to in this Section 2.11 and the conditions precedent in Article 9, the Borrower may obtain Swing Line Advances from the Swing Line Lender by delivering a Notice of Drawdown to the Swing Line Lender (with a copy to the Agent) not later than 9:00 a.m. (Calgary, Alberta local time) on the proposed Drawdown Date.  The making of each Swing Line Advance shall constitute a Drawdown hereunder and shall reduce the availability of the Credit Facility by the U.S. Equivalent of such Swing Line Advances.  All interest payments and principal payments made by the Borrower in respect of Swing Line Advances shall be made directly to the Swing Line Lender at the account designated to the Borrower for such purpose and shall be for the sole account of the Swing Line Lender (except as provided otherwise in Section 2.11(f)).

The Borrower may repay Swing Line Advances at any time;providedthat it shall deliver a Notice of Rollover/ Conversion/Repayment to the Swing Line Lender (with a copy to the Agent) not later than 11:00 a.m. (Calgary, Alberta local time) on the proposed repayment date.  In addition, if the Borrower requests a Syndicated Advance and the Swing Line Lender's Pro Rata Share of such Syndicated Advance would cause its Pro Rata Share of all Syndicated Advances then outstanding together with all Swing Line Advances then outstanding to exceed its Commitment, then the Borrower shall be required to repay such Swing Line Advances to the extent of such excess on or before the requested date of such requested Syndicated Advance.  Swing Line Advances cannot be converted except for Conversions into Syndicated Advances.

|(d) | Mandatory Conversion of Swing Line Advances.  The Swing Line Lender may at any time in its sole and absolute discretion, on behalf of the Borrower (which hereby irrevocably directs and authorizes the Swing Line Lender to make such request on its behalf ), request a Conversion of any Swing Line Advance into a Syndicated Advance (which shall be a Prime Loan or a USBR Loan) in an amount equal to the principal amount of such Swing Line Advance and accrued interest thereon;providedthatthe provisions of this Section 2.11(d) shall not affect the Borrower's obligation to repay the Swing Line Advances.  Unless the Commitments of the Lenders shall have expired or terminated (in which event the procedures of Section 2.11(e) shall apply), each Lender shall remit its Pro Rata Share of any such Syndicated Advance to the Agent's Account, and the Agent shall make such funds available to the Swing Line Lender at the Designated Lending Branch of the Swing Line Lender, in each case for same day value on the Banking Day next following the date such notice is

|(e) | Purchase of Participations.  If the Commitments of all of the Lenders expire or terminate at any time while Swing Line Advances are outstanding, each Lender (other than the Swing Line Lender) shall immediately purchase an undivided participating interest in the outstanding Swing Line Advances in an amount equal to its Pro Rata Share (determined on the date of, and immediately prior to, expiration or termination of the Commitments of the Lenders) of the aggregate principal amount of the outstanding Swing Line Advances by immediately paying to the Swing Line Lender, for same day value, the amount of its participation.

|(g) | Each Lender may at any time and from time to time hold, sell, rediscount or otherwise dispose of any or all Bankers' Acceptances accepted and purchased by it for its own account.

4.6  Escrow Funds


Upon the occurrence of an Event of Default or as otherwise provided herein, the Borrower will forthwith pay to the Agent for deposit into an escrow account maintained by and in the name of the Agent for the benefit of the Lenders, an amount equal to the aggregate face amount of the then outstanding Bankers' Acceptances (the " Escrow Funds ").  The Escrow Funds will be held by the Agent for set‐off against future indebtedness owing by the Borrower to the applicable Lenders in respect of such Bankers' Acceptances and prior thereto will bear interest at the rate declared by the Agent from time to time as that payable by it in respect of deposits for such amount and for the period from the date of deposit to the maturity date of the applicable Bankers' Acceptances.  If such Event of Default is either waived or cured in compliance with the terms of this Agreement, then the remaining Escrow Funds, if any, together with any accrued interest to the date of release, will be released to the Borrower.


4.7  BA Equivalent Loans


Notwithstanding the other provisions of this Article 4, a Non-BA Lender shall, in lieu of accepting and purchasing Bankers' Acceptances, make a BA Equivalent Loan.  The amount of each BA Equivalent Loan shall be equal to the BA Discount Proceeds which would be realized from a hypothetical sale of those Bankers' Acceptances to such Non-BA Lender which such Lender would otherwise be required to accept and purchase as part of such a BA Issue.  To determine the amount of such BA Discount Proceeds, the hypothetical sale shall be deemed to take place at the BA Discount Rate and using the BA Period for such BA Issue.  Any BA Equivalent Loan shall be made on the relevant Drawdown Date, Rollover Date or Conversion Date, as the case may be, and shall remain outstanding for the term of the relevant Drawdown or Rollover of, or Conversion into, Bankers' Acceptances issued concurrently therewith.  Concurrently with the making of a BA Equivalent Loan, a Non-BA Lender shall be entitled to deduct therefrom an amount equal to the BA Stamping Fee which such Lender would otherwise be entitled to receive pursuant to Section 3.4 as part of such BA Issue if such Lender was accepting Bankers' Acceptances, based on the amount payable on the maturity date of such BA Equivalent Loan.  The BA Equivalent Loan shall accrue interest at a rate per annum equal to the BA Discount Rate for the term of such BA Equivalent Loan.  Upon the maturity date for such Bankers' Acceptances, the Borrower shall pay to each Non-BA Lender, in satisfaction of the face amount of its BA Equivalent Loan plus interest accrued thereon, an amount equal to the face amount of the Discount Notes issued by the Borrower in respect of its BA Equivalent Loans, failing which such amount shall be converted to a Prime Loan (if denominated in Cdn. Dollars) or a USBR Loan (if denominated in U.S. Dollars).  As set out in the definition of "Bankers Acceptances", that term includes Discount Notes and all provisions of this Agreement applicable to Bankers' Acceptances shall apply equally to Discount Notes evidencing BA Equivalent Loans with such changes as may in the context be necessary.  All references in this Agreement to "Advances" and "BA Issue" shall, unless otherwise expressly provided herein or unless the context otherwise requires, be deemed to include BA Equivalent Loans made by a Non-BA Lender as part of a Drawdown or Rollover of, or Conversion into, Bankers' Acceptances.

|(a) | The Borrower shall pay to the LC Issuer sufficient funds in the currency of the relevant Letter of Credit, either immediately on demand by the LC Issuer, to reimburse the LC Issuer for any payment made by it pursuant to such Letter of Credit, or at the option of the LC Issuer by prior written notice to the Borrower, on or prior to the date on which any payment is to be made by the LC Issuer pursuant to such Letter of Credit, to fund such payment by the LC Issuer.  If the Borrower does not make any payment required by the preceding sentence, the LC Issuer may (but shall not be obliged to), without receipt of a Notice of Drawdown and irrespective of whether any other applicable conditions precedent specified herein have been satisfied, and without waiver of the Default constituted by the Borrower's failure to make such required payment, make a Prime Loan where the currency of such required payment is Cdn. Dollars or a USBR Loan where the currency of such required payment is in any currency other than Cdn. Dollars, to the Borrower in the aggregate amount of such required payment, and shall forthwith give notice thereof to the Borrower and the Agent.  For the purposes of determining the principal amount of such USBR Loan where the currency of the required payment is not U.S. Dollars, the required payment shall be converted into U.S. Dollars on the basis of the actual exchange rate obtained by the LC Issuer to purchase the required amount of such other currency on the date of the required payment.  The Borrower agrees to accept each such Advance and hereby irrevocably authorizes and directs the LC Issuer to apply the proceeds thereof in payment of the liability of the Borrower with respect to such required payment.

|(b) | Each of the Lenders, other than the LC Issuer, agrees that it shall purchase from the LC Issuer, and the LC Issuer shall sell to such Lenders, for cash, at par, without representation or warranty from or recourse to the LC Issuer, (and irrespective of whether any condition precedent to an Advance has been met, whether any Default or Event of Default has occurred or is continuing or whether any acceleration or any enforcement action (including any termination of the Commitments) has occurred or commenced under the Loan Documents or otherwise or whether the Maturity Date has lapsed) on a Pro Rata Basis, an undivided interest in any Advance made by the LC Issuer pursuant to Section 5.2(a), immediately upon such Advance being made.  The LC Issuer, upon consultation with the purchasing Lenders, shall have the power to settle any documentation required to evidence any such purchase and, if deemed advisable by the LC Issuer, to execute any document as attorney for any Lender in order to complete any such purchase.  The Borrower and the Lenders acknowledge that the foregoing arrangements are to be settled by the Lenders among themselves, and the Borrower expressly consents to the foregoing arrangements among such Lenders.  Notwithstanding that any Lender may assign its rights and obligations hereunder, the obligations in this Section 5.2(b) shall continue as obligations of the Persons who were Lenders at the time each such Letter of Credit was issued, unless the LC Issuer

|(c) | If a domestic or foreign court issues any judgment or order extending the liability of the LC Issuer to make payment under such Letter of Credit beyond the expiry date specified therein, the Borrower shall forthwith upon demand by the LC Issuer pay to the LC Issuer, funds in the currency of such Letter of Credit and in the amount of the Advance constituted by such Letter of Credit.  Such funds (together with interest thereon) shall be held by the LC Issuer for payment of the liability of the Borrower pursuant to Section 5.2(a) or otherwise in respect of such Letter of Credit so long as the aforementioned judgment or order remains in force and the LC Issuer has or may in any circumstance have any liability under such Letter of Credit, and shall bear interest for such terms as are selected from time to time by the LC Issuer at the wholesale money market rate of the LC Issuer for deposits of similar currency, amounts and maturities.  Any balance of such funds and interest remaining at such time as the LC Issuer does not have and may never have any liability under such Letter of Credit shall nevertheless continue to be held by the LC Issuer, if and so long as any Default or Event of Default is continuing, as security for the remaining liabilities of the Borrower under the Loan Documents.

|(a) | Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable Laws.  If any applicable Laws (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Taxes from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable Laws and, if such Taxes are Indemnified Taxes, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.  The Loan Parties shall jointly and severally indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.  As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section 6.3, such Loan Party shall deliver to the Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent.

|(b) | Each Lender shall severally indemnify the Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that any Loan Party has not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 15.1 relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.  A certificate as to the amount of such payment or liability delivered to any Lender by the Agent shall be conclusive absent manifest error.  Each Lender hereby authorizes the Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender from any other source against any amount due to the Agent under this paragraph (b).

|(c) | Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably requested by the Borrower or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will permit such payments to be made without withholding or at a reduced rate of withholding.

|(d) | If a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA, such Lender shall deliver to the Borrower and the Agent at the time or times prescribed by Law and at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by applicable Law and such additional documentation reasonably requested by the Borrower or the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment.  Solely for purposes of this clause (d), “FATCA” shall include any amendments made to FATCA after the Effective Date.

10.3  Sharing Security


The Borrower and the Lenders agree and acknowledge that the Security is being held by the Agent to secure firstly the Loan Indebtedness and the Senior Secured Swap Obligations on a senior basis (and on a pari passu basis within these senior obligations) and secondly any Subordinate Secured Swap Obligations on a subordinate basis (and on a pari passu basis within these subordinate obligations), as more particularly contemplated below.  For purposes of the above sentence, pari passu basis means:


|    |                                                                                                                                                                          
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(a) | with respect to the Lenders, proportional between (i) the Loan Indebtedness and (ii) the aggregate of the Loan Indebtedness plus the Senior Secured Swap Obligations; and

|    |                                                                                                                                                                                         
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(b) | with respect to the Swap Lenders, proportional between (i) the Senior Secured Swap Obligations and (ii) the aggregate of the Loan Indebtedness plus the Senior Secured Swap Obligations.

The Swap Lenders, as among themselves, will share their pro rata allocation of the Security, as determined in paragraph (c) above in the case of Senior Secured Swap Obligations, based on a pro rata allocation of the aggregate outstanding Senior Secured Swap Obligations owing to each Swap Lender.


The Swap Lenders, as among themselves, will share their subordinate allocation of the Security, as determined in paragraph (c) above in the case of Subordinate Secured Swap Obligations, on a pari passu basis based upon a pro rata allocation of the outstanding Secured Swap Obligations owing to each Swap Lender.


Although Excluded Swap Obligations with respect to any Loan Party shall not be paid with amounts received from such Loan Party or its assets, at the discretion of the Agent and to the extent not prohibited by Law, appropriate adjustments shall be made with respect to payments from other Loan Parties to preserve


62


---




the allocation to Loan Indebtedness and Secured Swap Obligations that would have resulted in accordance with this Section 10.3 assuming that, solely for purposes of such adjustments, Secured Swap Obligations included Excluded Swap Obligations.


If requested by any of the Agent, the Majority Lenders or any Swap Lender, then each of the Agent and the Swap Lenders will enter into such further intercreditor agreements and assurances as may be reasonably requested to further evidence the sharing provisions of this Section 10.3.  In addition to the pari passu sharing provisions referred to above, such further agreements shall incorporate the following principles:


|    |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(a) | no Swap Lender may enforce the Security (without the Lenders) unless the Borrower defaults in paying any Secured Swap Obligations then due and owing to such Swap Lender in excess of the U.S. Equivalent of U.S. $25,000,000 and such default continues for at least 30 days;providedthat any such Secured Swap Obligations not paid by the Borrower by the end of such 30 day period may, at the option of the Lenders and to the extent of any undrawn availability under the Total Commitment, be paid by the Lenders and shall be deemed to constitute a Prime Loan (if denominated in Cdn.

|(b) | after the Lenders or any Swap Lender(s) elect to enforce the Security, any decision or determination which is required to be made by the enforcing secured parties regarding the conduct of such enforcement shall be determined by the enforcing Lenders (if the Loan Indebtedness exceeds the Senior Secured Swap Obligations of the enforcing Swap Lenders) or by the enforcing Swap Lender(s) (if the Senior Secured Swap Obligations of the enforcing Swap Lender(s) exceeds the Loan Indebtedness or if and for so long as the Lenders have not elected to enforce the Security); and

|    |

|(c) | no Swap Lender may receive any proceeds of realization from the Security in respect of the Subordinate Secured Swap Obligations until after the Loan Indebtedness and the Senior Secured Swap Obligations have been repaid in full.

As among the Lenders and the Swap Lenders, the above principles are intended to apply at all times (whether before or after the execution of any intercreditor agreement entered into to further evidence the sharing provisions in this Section 10.3) but are not intended to apply to any enforcement of the Swap Guarantee on an unsecured basis.


For clarity, any intercreditor agreement that may be entered into with the holders of Pari Passu Debt will govern as between the Lenders and the Swap Lenders on the one hand and the holders of the Pari Passu Debt on the other hand.


10.4  Form and Amount of Security


If the Agent, acting reasonably, determines at any time and from time to time that the form and nature of the then existing Security is deficient in any way or does not fully provide the Agent and the Lenders and the Swap Lenders with the Security and priority to which each is entitled hereunder, the Borrower will forthwith execute and deliver or cause to be executed and delivered to the Agent, at the Borrower's expense, such amendments to the Security or provide such new security as the Agent may reasonably request.


The forms of Security shall have been or be prepared based upon the Laws of Canada and Alberta applicable thereto in effect at the date hereof.  The Agent shall have the right to require that:


|    |

|(b) | the Borrower execute and deliver to the Agent such other and further debentures, mortgages, trust deeds, assignments and security agreements as may be reasonably required to ensure the Agent, the Lenders and the Swap Lenders have and hold, subject to Permitted Liens, an effective floating charge or security interest over all of the property and assets of the Borrower (other than the Fixed Charge Assets) and a first priority fixed charge over all of the Fixed Charge Assets.

10.5  After-Acquired Property


All property acquired by or on behalf of the Borrower after the date of execution of the Security (hereinafter collectively referred to as " After-Acquired Property "), will be subject to the charges and security interests of the Debenture , without any further conveyance, mortgage, pledge, charge, assignment or other act on the part of the Borrower .  Without limiting the effect of the preceding sentence, but subject to Section 10.2 , the Borrower will from time to time execute and deliver, or cause to be executed and delivered, and the Agent will register, all at the Borrower 's expense, such instruments supplemental to the Security , in form and substance satisfactory to the Agent , acting reasonably, as may be necessary or desirable to ensure that the Security as amended and supplemented constitutes in favour of the Agent , the Lenders and the Swap Lenders an effective floating charge or security interest over such After-Acquired Property as required hereunder .


10.6  Continuing Security


Each item or part of the Security shall for all purposes be treated as a separate and continuing collateral security and shall be deemed to have been given in addition to and not in place of any other item or part of the Security or any other security now held or hereafter acquired by the Agent or the Lenders. No item or part of the Security shall be merged or be deemed to have been merged in or by this Agreement or any documents, instruments or acknowledgements delivered hereunder, or any simple contract debt or any judgment, and any realization of or steps taken under or pursuant to any security, instrument or agreement shall be independent of and not create a merger with any other right available to the Lenders or the Agent under any security, instruments or agreements held by it or at Law or in equity.


10.7  Dealing with Security


The Agent, with the consent of all of the Lenders, may grant extensions of time or other indulgences, take and give up securities (including, without limitation, the Security or any part or parts thereof), accept compositions, grant releases and discharges and otherwise deal with the Borrower and other Parties and with security (including without limitation, the Security and each part thereof) as the Agent may see fit, and may, subject to Section 10.3, apply all amounts received from the Borrower or others or from securities (including without limitation, the Security or any part thereof) upon such part of the liabilities of the Borrower hereunder or under any of the Security as the Agent may think best, without prejudice to or in any way limiting the liability of the Borrower under this Agreement or under any of the Security or any other collateral security.


10.8  Effectiveness


The Security shall be effective, and the undertakings as to the Security herein or in any other Loan Document shall be continuing, whether any Loan Indebtedness is then outstanding or any amounts thereby secured or any part thereof shall be owing before or after, or at the same time as, the creation of such Security or before or after or upon the date of execution of any amendments to this Agreement.


10.9  Permitted Liens


The Agent will, at the sole expense of the Borrower, forthwith upon request by the Borrower, execute and deliver to the Borrower, any other Loan Party and any third party as requested by the Borrower, such discharges or postponements of the Security Documents and the Liens constituted thereby as the Borrower


64


---




may reasonably request in order to permit such Loan Party to create, incur, allow to be created or permit to exist any Lien which, in the opinion of the Agent (acting reasonably), is intended to rank in priority to the Security.


10.10  Permitted Dispositions


The Agent will, at the sole expense of the Borrower, forthwith upon request by the Borrower, execute and deliver to the Borrower, any other Loan Party and any third party as requested by the Borrower, such releases, discharges or letters of no interest in respect of the Security Documents as the Borrower may reasonably request in order to permit such Loan Party to effect dispositions that are permitted by Section 8.2(c) or that are not otherwise restricted by this Agreement.


10.11  Release and Discharge of Security


The Borrower shall not be discharged from the Security or any part thereof except by a written release and discharge signed by the Agent with the prior written consent of all Lenders and all of the Swap Lenders.  If all of the Loan Indebtedness and the Secured Swap Obligations have been repaid, paid, satisfied and discharged, as the case may be, in full and the Credit Facility has been fully cancelled, then the Security shall be released and discharged by the Agent and the Lenders. The Agent, at the cost and expense of the Borrower, shall from time to time do, execute and deliver, or cause to be done, executed and delivered, all such agreements, instruments, certificates, financing statements, notices and other documents and all acts, matters and things as may be reasonably requested by the Borrower to give effect to, establish, evidence or record the foregoing release and discharge.


10.12  Transfer of Security


If TD, in its capacity as Agent, or any successor thereto, in its capacity as Agent (the " Departing Agent ") ceases to be the Agent, the Departing Agent shall transfer and assign all of the Security to the replacement agent or, if the Credit Facility has been repaid and cancelled, to the Swap Lenders.


10.13  Keepwell


Without derogation from any Swap Guarantee, the Borrower hereby absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honour all of its obligations under its Restricted Subsidiary Guarantee in respect of Swap Obligations.  The Borrower intends that this Section 10.13 constitute, and this Section 10.13 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

|(b) | the imposition of any condition, restriction or limitation upon such Lender which is outside of its control,

then such Lender may, by written notice thereof to the Borrower and the Agent, declare its obligations under this Agreement in respect of such Advance to be terminated, and the Borrower shall forthwith (or at the end of such period as is permitted under the applicable Law) either effect a Conversion of such Advance in accordance with the provisions hereof (if such Conversion would resolve the unlawfulness or impossibility) or prepay to such Lender all principal amounts affected thereby, together with all unpaid interest accrued, such Additional Compensation as may be applicable with respect to such Advance to the date of such repayment and all other expenses incurred in connection with the termination of any such Advance, including any expenses resulting from the termination of any LIBOR Period relating thereto in accordance with Section 13.2 and all costs, losses and expenses incurred by the Lenders by reason of the liquidation or redeployment of deposits or other funds or for any other reason whatsoever resulting from the repayment of such Advance or any part thereof on other than the last day of the applicable interest period.  If the principal amount affected thereby relates to outstanding Bankers' Acceptances, such Lender may require the Borrower to deposit in an interest bearing account with such Lender (with interest to accrue for the benefit of the Borrower) such amount as may be necessary to fully satisfy the contingent obligations of such Lender for all outstanding Bankers' Acceptances and Letters of Credit in accordance with the arrangements set out in Section 4.6 (excepting out all references to an Event of Default).  The Borrower may utilize other forms of Advances not so affected in order to make any required repayment and, after any such repayment, the Borrower may elect to re-borrow the amount repaid by way of some other type of Advance upon complying with any other applicable requirements in this Agreement.

then the Agent shall give notice thereof to the Lenders and the Borrower as soon as possible after such determination or receipt of such LIBOR Suspension Notice, as the case may be, and the Borrower shall, within one Banking Day after receipt of such notice and in replacement of the Notice of Borrowing previously given by the Borrower, give the Agent a new Notice of Borrowing which specifies any other Drawdown or the Conversion of the relevant LIBOR Loan on the last day of the applicable LIBOR Period into any other Advance which would not be affected by the notice from the Agent pursuant to this Section 12.3.


In the event the Borrower fails to give, if applicable, a valid replacement Notice of Borrowing with respect to the maturing LIBOR Loans which were the subject of a Notice of Borrowing, such maturing LIBOR Loans shall be converted on the last day of the applicable LIBOR Period into USBR Loans as if a valid replacement Notice of Borrowing had been given to the Agent by the Borrower pursuant to the provisions hereof.  In the event the Borrower fails to give, if applicable, a valid replacement Notice of Drawdown with respect to a Drawdown originally requested by way of a LIBOR Loan, then the Borrower shall be deemed to have requested a Drawdown by way of a USBR Loan in the amount specified in the original Notice of Borrowing and, on the originally requested Drawdown Date, the Lenders (subject to the other provisions hereof) shall make available the requested amount by way of a USBR Loan.

A BA Suspension Notice shall be effective upon receipt of the same by the Agent if received prior to 12:00 noon (Calgary, Alberta local time) on a Banking Day and if not, then on the next following Banking Day, except in connection with a Notice of Borrowing previously received by the Agent, in which case the applicable BA Suspension Notice shall only be effective with respect to such previously received Notice of Borrowing if received by the Agent prior to 12:00 noon (Calgary, Alberta local time) two Banking Days prior to the proposed Drawdown Date, Conversion Date or Rollover Date (as applicable) applicable to such previously received Notice of Borrowing.


12.5  Application of Sections 12.1, 12.2, 12.3 and 12.4


If a Lender exercises its rights under this Article 12, then concurrently with a written notice from such Lender to the Borrower requiring compliance with the applicable provision, such Lender shall provide the Borrower with a certificate in reasonable detail outlining the particulars giving rise to such notice, confirming that its actions are consistent with actions concurrently taken by such Lender with respect to similar type provisions affecting other borrowers of such Lender in comparable circumstances and, in the case of Section 12.1, certifying (with reasonable supporting detail) the increased costs, if any, payable by the Borrower hereunder, which shall be prima facie proof thereof and binding on the Parties.


12.6  Designation of a Different Lending Office


If any Lender requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 6.3 or requests compensation under Section 12.1, or, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 6.3 or 12.1, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender.  The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

ARTICLE 13  COSTS, EXPENSES AND INDEMNIFICATION

The Agent or the Lenders, as the case may be, shall within a reasonable time give notice to the Borrower of any amounts payable by the Borrower under this Section 13.1 and such amounts shall be paid within 30 days thereafter.  Any amounts not so paid will bear interest at the rate set out in Section 3.8 from the date such cost or expense should have been paid until the Agent or the Lenders have been paid in full.

|    |

13.3  Currency Indemnity


Any payment made to or for the account of a Lender in respect of any amount payable by the Borrower in a currency (the " Tendered Currency ") other than the currency in which such payment is due (the " Required Currency "), whether pursuant to any judgment or order of a court or tribunal or otherwise, shall constitute a discharge of the Borrower only to the extent of the amount of the Required Currency which may be purchased with such Tendered Currency at the time of payment at the Noon Rate at such time.  The Borrower covenants and agrees to and in favour of each Lender that it shall, as a separate and independent obligation which shall not be merged in any such judgment or order, pay or cause to be paid the amount not so discharged in accordance with the foregoing and indemnify and hold harmless each Lender against any loss or damage arising as a result of any such amount being paid in such Tendered Currency.  A certificate of the Agent as to any such loss or damage shall be prima facie evidence of the amount thereof in the absence of manifest error.


13.4  LC Issuer Indemnity


The Borrower shall indemnify and save harmless the LC Issuer from all claims, demands, liabilities, damages, losses, costs, charges and expenses which may be asserted against or incurred by the LC Issuer, otherwise than as are determined by a court of competent jurisdiction to be attributable to the gross negligence or wilful misconduct of the LC Issuer, as a direct or indirect consequence of the issuance of any Letter of Credit at the request of the Borrower or of any failure by the LC Issuer to make any payment under any Letter of Credit issued at the request of the Borrower as a result of any law, control or restriction rightfully or wrongfully exercised or imposed by a domestic or foreign Governmental Authority.


13.5  Waiver of Consequential Damages, Etc.


To the fullest extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any loan or Letter of Credit, or the use of the proceeds thereof.  No indemnitee referred to in Sections 13.2 or 13.4 shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

|(a) | Unless the Agent has been notified by a Lender at least one Banking Day prior to the Drawdown Date requested by the Borrower that such Lender will not make available to the Agent its Pro Rata Share of the relevant Advance, the Agent may assume that such Lender has made or will make such portion of such Advance available to the Agent on the Drawdown Date in accordance with the provisions hereof and the Agent may, but shall be in no way obligated to, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount.  If and to the extent such Lender shall not have so made its Pro Rata Share of an Advance available to the Agent, such Lender agrees to pay to the Agent forthwith on demand such Lender's Pro Rata Share of the Advance and all reasonable costs and expenses incurred by the Agent in connection therewith together with interest thereon (at the usual inter-bank offered rate for the sale of deposits in the applicable currency or, if such Lender becomes a Defaulting Lender, the rate payable hereunder by the Borrower for the Advance in each case for each day from the date such amount is made available to the Borrower until the date such amount is paid to the Agent);provided,however, that notwithstanding such obligation if such Lender fails to so pay, the Borrower covenants and agrees that, without prejudice to any rights the Borrower may have against such Lender, it shall repay such amount to the Agent forthwith after demand therefor by the Agent.  The amount payable to the Agent pursuant hereto shall be set forth in a certificate delivered by the Agent to such Lender and the Borrower (which certificate shall contain reasonable details of how the amount payable is calculated) and shall beprima facieevidence thereof, in the absence of manifest error.  If such Lender makes the payment to the Agent required herein,

|(b) | After the Agent is notified by the Borrower of a pending sale of Bankers' Acceptances to third party purchaser(s) in accordance with Section 4.5(b), each Lender may, in its discretion, assume that the applicable purchaser will be remitting the applicable BA Discount Proceeds to such Lender on the applicable issue date in accordance with the Borrower's settlement instructions and such Lender may, in its discretion and in reliance upon such assumption, remit to the Agent on such issue date an amount equal to such BA Discount Proceeds (net of the BA Stamping Fee payable to such Lender) in accordance with Section 4.5(d).  If the applicable purchaser does not in fact remit such funds to such Lender on such issue date, such Lender shall promptly notify the Agent who shall promptly notify the Borrower and the Borrower shall forthwith, on demand by the Agent, pay to the Agent for the account of such Lender such amount together with such interest thereon as may be reasonably required to compensate such Lender for such purchaser's non-payment if such payment is not made on such issue date, as determined by such Lender in accordance with its usual banking practices.

14.3  Remittance of Payments


Except for amounts payable to the Agent for its own account, forthwith after receipt of any repayment of principal, interest or fees pursuant hereto, the Agent shall remit to the Designated Lending Branch of each Lender its Pro Rata Share of such payment; provided that, if the Agent, on the assumption that it will receive on any particular date a payment of principal, interest or fees hereunder, remits to a Lender its Pro Rata Share of such payment and the Borrower fails to make such payment, each of the Lenders on receipt of such remittance from the Agent agrees to repay to the Agent forthwith on demand an amount equal to the remittance together with all reasonable costs and expenses incurred by the Agent in connection therewith and interest thereon at the rate and calculated in the manner customarily applicable to interbank payments for each day from the date such amount is remitted to the Lenders without prejudice to any right such Lender may have against the Borrower.  The exact amount of the repayment required to be made by the Lenders pursuant hereto shall be as set forth in a certificate delivered by the Agent to each Lender, which certificate shall be conclusive and binding for all purposes in the absence of manifest error.


14.4  Redistribution of Payment


Each Lender agrees that:

|(i) | such Overpaid Lender shall purchase, on a non-recourse basis and at par, portions of the Outstandings owed to the other Lenders in an amount equal to the Excess Payment and in such proportions that after such purchase each Lender will be owed its Pro Rata Share of the Loan Indebtedness, whereupon the Agent shall notify the Borrower of such amount and of its receipt by the Agent;

|     |

|(g) | may refrain from exercising any right, power or discretion vested in it which would or might in its reasonable opinion be contrary to any Laws or any directive or otherwise render it liable to any Person, and may do anything which is in its reasonable opinion necessary to comply with such Laws.

Further, the Agent (i) does not make any warranty or representation to any Lender nor shall it be responsible to any Lender for the accuracy or completeness of the representations and warranties of the Borrower herein or the data made available to any of the Lenders in connection with the negotiation of this Agreement, or for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (ii) shall not have any duty to ascertain or to enquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of the Borrower or to inspect the property (including  the books and records) of the Borrower or any of its Subsidiaries; and (iii) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any instrument or document furnished pursuant hereto.


14.6  Prompt Notice to Lenders


Notwithstanding any other provision herein, the Agent agrees to provide to the Lenders, with copies where appropriate, all information, notices and reports required to be given to the Agent by the Borrower,

promptly upon receipt of same, excepting therefrom information and notices relating solely to the role of Agent hereunder.


14.7  Agent's and Lenders' Authorities


With respect to its Commitments and its Pro Rata Shares of the Drawdowns, Rollovers and Conversions made by it as a Lender, the Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Agent.  Subject to the express provisions hereof relating to the rights and obligations of the Agent and the Lenders in such capacities, the Agent and each Lender may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower and its Subsidiaries or any corporation or other entity owned or controlled by any of them and any Person which may do business with any of them without any duties to account therefor to the Agent or the other Lenders and, in the case of the Agent, all as if it was not the Agent hereunder.


14.8  Lender Credit Decision


It is understood and agreed by each Lender that it has itself been, and will continue to be, solely responsible for making its own independent appraisal of and investigations into the financial condition, creditworthiness, condition, affairs, status and nature of the Borrower and the Subsidiaries. Each Lender confirms to the Agent that it is engaged in the business of making and evaluating the risks associated with commercial revolving or term loans, or both, to corporations similar to the Borrower and the Subsidiaries, that it can bear the economic risks related to the transaction contemplated hereby, that it has had access to all information deemed necessary by it in making such decision (provided that this representation shall not impair its rights against the Borrower) and that it is entering into this Agreement in the ordinary course of its commercial lending business.  Accordingly, each Lender confirms with the Agent that it has not relied, and will not hereafter rely, on the Agent (i) to check or enquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Borrower or any other Person under or in connection with this Agreement or the transactions herein contemplated (whether or not such information has been or is hereafter distributed to such Lender by the Agent), or (ii) to assess or keep under review on its behalf the financial condition, creditworthiness, condition, affairs, status or nature of the Borrower and the Subsidiaries.  Each Lender acknowledges that a copy of this Agreement has been made available to it for review and each Lender acknowledges that it is satisfied with the form and substance of this Agreement.  Each Lender hereby covenants and agrees that it will not make any arrangements with the Borrower for the satisfaction of any Advances or other Loan Indebtedness without the consent of all other Lenders.


14.9  Indemnification of Agent


The Lenders hereby agree to indemnify the Agent (to the extent not reimbursed by the Borrower), 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 kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Agent under or in respect of this Agreement in its capacity as Agent; 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 the Agent's gross negligence or wilful misconduct.  If the Borrower subsequently repays all or a portion of such amounts to the Agent, the Agent shall reimburse the Lenders their Pro Rata Shares (adjusted according to the amounts paid by them in respect thereof) of the amounts received from the Borrower.  Without limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its portion (determined as above) of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preservation of any rights of the Agent or the Lenders under, or the enforcement of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower.

14.10  Successor Agent


The Agent may, as hereinafter provided, resign at any time by giving 45 days' prior written notice thereof to the Lenders and the Borrower.  Upon any such resignation, the Lenders shall, after soliciting the views of the Borrower, have the right to appoint another Lender as a successor agent (the " Successor Agent ") who shall be acceptable to the Borrower, acting reasonably.  If no Successor Agent shall have been so appointed by the Lenders and shall have accepted such appointment within 30 days after the retiring Agent's giving of notice of resignation, then the retiring Agent shall, on behalf of the Lenders, appoint a Successor Agent who shall be a Lender acceptable to the Borrower, acting reasonably.  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, powers, privileges and duties of the retiring Agent, and the retiring Agent shall thereupon be discharged from its further duties and obligations as Agent under this Agreement.  After any retiring Agent's resignation hereunder as Agent, the provisions of this Article shall continue to enure to its benefit as to any actions taken or omitted to be taken by it as Agent or in its capacity as Agent while it was Agent hereunder.

Notwithstanding any of the provisions contained herein, each of the Lenders hereby covenants and agrees that it shall not be entitled to individually take any action with respect to the Credit Facility, including, without limitation, any exercise of any remedies under Section 11.2, but that any such action shall be taken only by the Agent with the prior written agreement or instructions of the Majority Lenders;providedthat, notwithstanding the foregoing, if (i) the Agent, having been adequately indemnified against costs and expenses of so doing by the Lenders, shall fail to carry out any such instructions of the Majority Lenders, any Lender may do so on behalf of all Lenders and shall, in so doing, be entitled to the benefit of all protections given the Agent hereunder or elsewhere, and (ii) in the absence of instructions from the Majority Lenders and where in the sole opinion of the Agent the exigencies of the situation warrant such action, the Agent may without notice to or consent of the Lenders or any of them take such action on behalf of the Lenders as it deems appropriate or desirable in the interests of the Lenders.  Each of the Lenders hereby further covenants and agrees that upon any such written consent being given by the Majority Lenders, or upon a Lender or the Agent taking action as aforesaid, it shall cooperate fully with the Lender or the Agent to the extent requested by the Lender or the Agent in the collective realization including, without limitation, and, if applicable, the appointment of a receiver, or receiver and manager to act for their collective benefit.  Each Lender covenants and agrees to do all acts and things and to make, execute and deliver all agreements and other instruments, including, without limitation, any instruments necessary to effect any registrations, so as to fully carry out the intent and purpose of this Section; and each of the Lenders hereby covenants and agrees that it has not heretofore and shall not seek, take, accept or receive any security for any of the Loan Indebtedness of the Borrower hereunder or under any other document, instrument, writing or agreement ancillary hereto and shall not enter into any agreement with any of the Parties relating in any manner whatsoever to the Credit Facility (except as expressly contemplated under this Agreement), unless all of the Lenders shall at the same time obtain the benefit of any such security or agreement.

|(b) | If the Agent has actual knowledge that a Lender is a Defaulting Lender at the time that the Agent receives a Notice of Borrowing that relates to a Letter of Credit or that either relates to a Swing Line Advance or will result in a currency conversion, then each Non-Defaulting Lender shall fund its Lender's proportion of such affected Loan Indebtedness (and, in calculating such Lender's proportion, the applicable Commitment of each such Defaulting Lender shall be ignored);providedthat such re-allocation may only be effected if and to the extent that (i) such re-allocation would not cause any Non-Defaulting Lender's proportion of all Outstandings to exceed its Commitment and (ii) the conditions precedent in Section 9.2 are satisfied at such time.  Each Defaulting Lender agrees to indemnify each Non-Defaulting Lender for any amounts paid by such Non-Defaulting Lender under this Section 14.17 and which would otherwise have been paid by the Defaulting Lender if its Commitment had been included in determining the Lender's Pro Rata Share of such affected Advances.

Confirmation of Guarantees


Dated:     December 13, 2013


For good and valuable consideration (the receipt and sufficiency of which is hereby conclusively acknowledged) each of the undersigned in its capacity as a "Guarantor" pursuant to and as defined in its respective Restricted Subsidiary Guarantee hereby: (a) consents and agrees to the terms of this Restated Credit Agreement; (b) acknowledges and confirms the representations and warranties applicable to it in this Restated Credit Agreement; (c) agrees to and undertakes the covenants expressed to be applicable to it in the Restated Credit Agreement; and (d) acknowledges that its Restricted Subsidiary Guarantee remains in full force and effect in all respects notwithstanding the amendments contained in this Restated Credit Agreement and shall continue to exist and shall apply to all Loan Indebtedness and (subject to the next paragraph) Secured Swap Obligations, including without limitation the Loan Indebtedness of the Borrower under this Restated Credit Agreement.


Without derogation from the foregoing or any Restricted Subsidiary Guarantee, each of the undersigned that is a Qualified ECP Guarantor (each an " Applicable Guarantor ") hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Restricted Subsidiary to honour all of its obligations under its respective Restricted Subsidiary Guarantee in respect of Swap Obligations (provided, however, that each Applicable Guarantor shall only be liable hereunder for the maximum amount of such liability that can be hereby incurred without rendering its obligations hereunder, or otherwise under its own Restricted Subsidiary Guarantee, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Applicable Guarantor under this paragraph shall remain in full force and effect until its Restricted Subsidiary Guarantee is discharged in accordance with the Restated Credit Agreement or otherwise in accordance with its terms. Each Applicable Guarantor intends that this paragraph constitute, and this paragraph shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Restricted Subsidiary for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.


For the purposes of the foregoing paragraph, " Qualified ECP Guarantor " means, in respect of any Swap Obligation, each Restricted Subsidiary that has total assets exceeding $10,000,000 at the time the relevant Guarantee or grant of the relevant security interest becomes effective with respect to such Swap Obligation or such other person as constitutes an “eligible contract participant” under the Commodity Exchange Act or any regulations promulgated thereunder and can cause another person to qualify as an “eligible contract participant” at such time by entering into a keepwell under Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.


Notwithstanding the foregoing or any provision of any Restricted Subsidiary Guarantee, the Restricted Subsidiary Guarantee of each of the undersigned shall not guarantee or apply in respect of any Excluded Swap Obligations, and for this purpose the definition of "Obligations" in each such Restricted Subsidiary Guarantee shall be deemed to exclude Excluded Swap Obligations.


Except to the extent expressly set out herein, this Confirmation is in addition to and shall not limit, derogate from or otherwise affect the provisions of the Security, as amended to the date hereof.


Capitalized terms used herein shall have the same meanings herein as are ascribed thereto in the Restated Credit Agreement.

|8. | Foreign Currency Obligations.  The Guarantor will make payment of each Obligation in the currency (the "Original Currency") in which the Borrower is required to pay such Obligation.  If the Guarantor makes payments relative to any Obligation to the Agent or any Lender in a currency other than the Original Currency (whether voluntarily or pursuant to an order or judgment of a court or tribunal of any jurisdiction), such payment will constitute a discharge of the liability of the Guarantor hereunder in respect of such Obligation only to the extent of the amount of the Original Currency which the Agent is able to purchase at Toronto, Ontario with the amount it received on the date of receipt.  If the amount of the Original Currency which such Agent is able to purchase is less than the amount of such currency originally due to it in respect to the relevant Obligation, the Guarantor will indemnify and save the Agent and each Lender harmless from and against any loss or damage arising as a result of such deficiency.  This indemnity will constitute an obligation separate and independent from the other obligations contained in this Guarantee, will give rise to a separate and independent cause of action, will apply irrespective of any indulgence granted by the Agent, for and on behalf of the Lenders it represents, and will continue in full force and effect not withstanding any judgment or order in respect of any amount due hereunder or under any judgment or order.

|9. | Taxes and Set-off by Guarantor.  All payments to be made by the Guarantor hereunder will be made without set-off or counterclaim and without deduction for any taxes, levies, duties, fees, deductions, withholdings, restrictions or conditions of any nature whatsoever.  If at any time any Law, regulation or international agreement requires the Guarantor to make any such deduction or withholding form any such payment, the sum due from the Guarantor with respect to such payment will be increased to the extent necessary to ensure that, after the making of such deduction or withholding (including any deduction or withholding on additional amounts paid pursuant to this

C-4

Section 9), the Agent, for its own benefit and on behalf of the Lenders, receives a net sum equal to the sum which it would have received had no deduction or withholding been required.

2.4  Additional Collateral


Each of the Secured Parties agrees that it (a) will not take, assume or hold any Security Interest in or upon or assignment of any assets which in any manner secures or would secure any of the Secured Obligations unless such Security Interest or assignment is granted to or assigned to the Collateral Agent to secure the payment of all of the Secured Obligations on a pari passu basis pursuant to an Additional Security Document, and (b) will not require that any party hereto other than the Collateral Agent be named as an additional loss payee under any insurance policy obtained by a NOVA Party in respect of the risk of loss or destruction of or damage to any of the Collateral.

If, notwithstanding the request of the Collateral Agent, any applicable Secured Party shall fail or refuse promptly to certify as to the existence or amount of any Secured Obligations, Principal Obligations, any Commitments or any portion thereof, the Collateral Agent shall be entitled to determine such existence or amount by such method as the Collateral Agent may, in its reasonable discretion, determine, including by reliance

|(b) | From time to time upon the request of the Collateral Agent (which request shall be made by the Collateral Agent, without limitation, at the reasonable direction of any Secured Party), the Borrower shall promptly deliver to the Collateral Agent a list setting forth, as of a specified date not more than 10 days prior to the date of delivery, the aggregate Secured Obligations then outstanding and Commitments and the name and address of each Secured Party and the respective amounts of Secured Obligations then outstanding and Commitments attributable to each.  The Collateral Agent shall provide a copy of the most recent list delivered to it under this Section 3.2 to any Secured Party upon request.

3.3  Restrictions on Actions


Each Secured Party agrees that, unless and until this Agreement is terminated as provided herein, or unless the Collateral Agent fails to exercise its obligations hereunder, including to enforce the Security Documents in the case of delivery of a Notice of Enforcement if and when required to do so in accordance with Section 4.2 (in which case the Majority Enforcing Secured Parties shall be entitled to exercise the rights and remedies under the Security Documents for and on behalf of, and in the name of, the Collateral Agent five (5) Business Days after having given notice to the Collateral Agent and the other Secured Parties of such failure and of their intention so to do), the provisions of this Agreement shall provide the exclusive method by which any Secured Party may exercise, or direct the exercise of, rights and remedies under the Security Documents.  Therefore, each Secured Party shall, for the mutual benefit of all Secured Parties refrain from taking or filing any action, judicial or otherwise, to enforce any rights or pursue any remedies under the Security Documents, except for delivering notices hereunder and as provided for above; provided that the foregoing shall not prevent (a) any Secured Party from imposing a default rate of interest in accordance with the applicable Credit Documents, or (b) a Secured Party from exercising its rights and remedies as an unsecured creditor in accordance with the applicable Credit Documents and applicable law, including the right to commence legal proceedings as an unsecured creditor to collect any Secured Obligations due and payable to such Secured Party and remaining unpaid, to demand payment of, or accelerate the maturity of, any Secured Obligations or to terminate any Commitment in accordance with the applicable Credit Documents, to commence legal proceedings to enforce any Credit Documents and obtain a judgment and to enforce such judgment, in each case to the same extent as if such Secured Party were an unsecured creditor.  If the Majority Enforcing Secured Parties exercise or purport to exercise the rights and remedies under the Security Documents as contemplated by the first sentence of this Section 3.3, any Proceeds of Realization thereby realized shall be deposited in the Enforcement Collateral Account and the provisions of Article 4 applicable to the Collateral Agent shall apply, mutatis mutandis, to such Enforcing Secured Parties.


3.4  Sharing of Information


If a Notice of Default or Notice of Event of Default has been given under Section 4.1(a) and remains outstanding, each of the Secured Parties may, but shall not be obligated to (except as required by Section 3.2), provide each other with such information as to the status of the Secured Obligations, and the Commitments and information concerning the Security Documents, the Collateral, and the financial position, property, assets and undertaking of the NOVA Parties, as such other may from

time to time reasonably request, and each NOVA Party consents to such disclosure and sharing of information, subject to the recipient of such information agreeing to be bound by all confidentiality restrictions applicable to the disclosing Secured Party.  Notwithstanding the foregoing, no Secured Party will be deemed to have represented the accuracy of such information absent an express written warranty to that effect, and no party hereto shall have any liability to any other party for any inaccuracy therein or reliance thereon by the recipient.

|(a) | Each Secured Party agrees that, except as provided below and under Section 3.3, any enforcement of the Security Documents cannot occur unless a Notice of Enforcement is given to the Collateral Agent by or on behalf of one or more Secured Parties meeting the conditions set forth in Section 4.1(c); provided, however, that forthwith upon receipt of a notice given in accordance with Section 4.1(c)(iii) the Collateral Agent shall give the NOVA Parties a notice of its intention to enforce the Security Documents pursuant to the provisions of theBankruptcy and Insolvency Act(Canada), or any successor legislation thereto, and to enforce the Security Documents as set out in this paragraph.  Whenever a Notice of Enforcement has been given, the Collateral Agent shall enforce the Security Documents and realize upon the Collateral in accordance with this Section 4.2.  Unless otherwise directed in writing by all of the Enforcing Secured Parties, the Collateral Agent shall enforce the Security Documents by way of seeking the appointment of a court-appointed Receiver in respect of the applicable NOVA Parties.  The Collateral Agent shall otherwise enforce the Security Documents and realize upon the Collateral in a commercially reasonable manner and in accordance with any directions given by the Majority Enforcing Secured Parties (including any directions requested in accordance with Section 4.2(b)); provided such directions are not inconsistent with or contrary to the provisions of this Agreement, any other Security Document or any applicable law and subject to the right of the applicable Enforcing Secured Parties to deliver a Notice of Cancellation of Enforcement in accordance with Section 4.1(e).  Each Enforcing Secured Party agrees that it will cooperate with the Collateral Agent, any Receiver and the other Enforcing Secured Parties and provide the Collateral Agent and any Receiver with reasonable enforcement directions, all with a view to maximizing the Proceeds of Realization.

|(c) | To the extent that the Borrower fails to pay any amount required to be paid by it to the Collateral Agent or any other Indemnitee under subsection (a) or (b) of this Section 5.2, each Secured Party (in respect of an amount payable by the Borrower prior to a Notice of Enforcement having been given) or each Enforcing Secured Party (in respect of an amount payable by the Borrower after a Notice of Enforcement has been given), as the case may be, severally agrees to pay to the Collateral Agent or such Indemnitee such Secured Party's or Enforcing Secured Party's (as applicable) pro rata share of such unpaid amount as determined as of the time that the applicable unreimbursed expense or indemnity payment became payable by the Borrower and based on the ratio that the Secured Obligations outstanding to such Secured Party or Enforcing Secured Party bear to the Secured Obligations then outstanding to all Secured Parties or all Enforcing Secured Parties, respectively; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Collateral Agent or such other Indemnitee in its capacity as such.  Each Secured Party and Enforcing Secured Party agrees to execute, deliver and perform such further assurances with respect to its obligations under this Section 5.2(c) as the Collateral Agent may from time to time request pursuant to this Section 5.2(c), and each shall contribute its pro rata share (determined on the same basis) of the excess of any payment made by any other Secured Party to the Collateral Agent or any other Indemnitee under Section 5.1 over such other Secured Party's several pro rata share of the required indemnification payment.  The Borrower shall indemnify each Secured Party against any payments by such Secured Party under Section 5.1.

|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(d) | To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby.

|    |

|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|(f) | Notwithstanding the foregoing, if and for so long as the Collateral Agent is either the Existing Facility Agent or the New Facility Agent, then Sections 5.2(a), 5.2(b) and 5.2(d) and the last sentence of Section 5.2(c) shall be deemed to not apply and the applicable fee and indemnity provisions in the Existing Facility Documents or the New Facility Documents, as applicable, shall govern in the place of these provisions.

|(a) | No failure or delay by the Collateral Agent in exercising any right or power hereunder or under any other Security Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.  The rights and remedies of the Collateral Agent hereunder and under the other Security Documents are cumulative and are not exclusive of any rights or remedies that it would otherwise have.  No waiver of any provision of any Security Document or consent to any departure by any NOVA Party therefrom shall in any
